The technical field to which the invention relates.

The present invention relates to a processing cartridge, and electrophotographic device to create the image.

Here, under the electrophotographic device image creation means a device designed to produce an image on the recording medium using one of the electrophotographic ways of creating images. Examples of the electrophotographic device, images are electrophotographic copying machine, electrophotographic printer (for example, led printer (LED, Light-Emitting Diode light - emitting diode), laser printer etc), electrophotographic facsimile machine, an electrophotographic office system, word processing, etc.

Here, under the process cartridge means a cartridge in which, forming a single unit placed electrophotographic photosensitive member and at least one of the following: a charging element and a processing element, as processing tools, which can remove installed in the main unit electrophotographic device to create the image.

Under it also means a cartridge in which, forming a single whole, posted by means of charging, the medium is in processing or cleanup tool, and electrophotographic photosensitive member that can remove installed in the main unit electrophotographic device to generate an image; a cartridge in which, forming a single unit, placed at least one of the following: a means of charging, tool development and tool cleaning, as well as electrophotographic photosensitive member that can remove installed in the main unit electrophotographic device to create the image. In addition, under this cartridge means a cartridge in which, forming a single whole, posted, at least, the tool developer, and electrophotographic photosensitive member that can remove installed in the main unit electrophotographic device to create the image.

(1) Electrophotographic device to create an image that uses the processing cartridge allows the user to set the processing cartridge into the main unit of the device or remove it, without the need for a service technician, which drastically increases the convenience and ease of use of the electrophotographic device of the image.

To create the image using electrophotographic the first device, the image it is necessary to apply voltage to the element charging to charge the electrophotographic photosensitive member (hereinafter referred to as photosensitive drum) processing cartridge, item development for the manifestation of the latent electrostatic image created on the photosensitive drum, etc.

With the above purpose, namely, to establish electrical connection between the process cartridge and the main unit electrophotographic device, the image, the body of the cartridge and the casing of the main unit is equipped with electric contacts. As a result, when the cartridge is installed in the main unit, a connection is established between the electrical contacts of the cartridge and corresponding electrical contacts of the main unit, making it possible to supply the toner cartridge voltage from the main unit.

More specifically, it is known the following constructive solution.

Main unit electrophotographic device, image supplied with a movable protective plate, which covers the electrodes (electrical contacts of the main unit), preventing thereby the contact of the operator and/or tools with the electrodes during maintenance of the printer (device image). When inserting the cartridge in the main unit, the cover plate is moved to the designated position, thus allowing to establish electrical connection between electrodes placed on the side of the main unit, and electrodes (electrical contacts) of the cartridge (application for Japanese patent 7-77921: Figure 1 - Figure 3).

In addition, when a node is removed from the main unit of the device, the contact pins (electrical contacts of the main unit of the device) is disposed behind the partition, preventing, thus, the contact for a service technician or a user with these pins at the same time when the above-mentioned node is inserted into the main unit of the device, the contact pins are forcibly ejected into the compartment of the cartridge, in which the node is installed, thus making it possible to establish electrical connections between the contact pins and the counter-contact part (electrical contact side of the cartridge) of this node (application for Japanese patent 62-215278 (string 15 bottom left paragraph page 4 - line 15 to the upper-left paragraph of page 6)).

Electrodes (electrical contacts of the main unit) have the ability to move between the designated position and a normal position, which allows the electrical contacts of the cartridge and the electrodes of the main unit of the device to connect to each other properly. More specifically, -the s cartridge from the main unit of the device causes movement of the electrodes (electrical contacts of the main unit) to the appropriate designated position prior to insertion of the cartridge into the main unit device the electrodes are designated position), at the same time insert the cartridge into the main unit of the device causes movement of the electrodes back into normal position, allowing the electrical connection between the electrodes and electrical contacts (application for Japanese patent 9-68833).

(2) In recent years, we have developed various products that use a cartridge containing a memory (storage element), which stores various data maintenance and/or operation. Application data stored in the cartridge memory, led to a further improvement of the electrophotographic device, the image from the point of view of its maintenance. To use this data allows connection of the memory cartridge to the main unit electrophotographic device of the image, which becomes possible as a result of the establishment of electrical connections between the contacts of the cartridge and the main unit of the device.

Even in the electrophotographic device to create an image that uses the processing cartridge is installed in the main unit this unit is that you can remove, sometimes there is a problem of jamming of the recording media such as paper, into the main unit. If this problem is and occurs the user pulls the processing cartridge from the main unit and remove the jammed paper. Then he re-inserts the processing cartridge. If you shot the processing cartridge is charged by static electricity, it is likely that during his re-installed in the main unit will generate electric discharge between the cartridge and open the electrical contacts of the main unit of the device. So to correct the problem lies in the fact that this type of electric charge will create an electrostatic interference in the electric circuit device to generate the image, some devices create images supplied by element removal of static electricity (application for Japanese patent 10-63166).

Next will be described the contacting portion and the locking portion of the cartridge C. the Contacting and fixing of the cartridge To actuate respectively the locking element of the main unit And the device, and the movable element of the main unit And the device.

Figure 10 is a General view of the cartridge C. the Housing 118 of the drum includes a photosensitive drum 107, the roller 108 charging, Raquel 117a, etc. that are installed in this building, forming a single whole. One end of the photosensitive drum 107 rotatably installed in the Lu 139 drum. The shaft 139 drum rotatably fixed in the Central hole of the guide element 140L1 cartridge in which the cartridge rests on the return part of the main unit And the device when the cartridge is installed in this unit. The contact part 140L1a, serving as the first contact part and which is the portion of the guide element 140L1 cartridge performs the function of making contact with the movable element of the main unit And the devices. Guide 140L1 cartridge is equipped with a number of radial ribs 140L1b passing from the edge of the center hole of the guide element 140L1 cartridge to the periphery of this element. In addition, guide 140L1 cartridge provided with a projecting part 141, which extends from the periphery of this element in the direction of the end cap 121. The external main surface of the protruding part 141, serving as the contact area a, works as a first fixing part, designed to hold the locking element in the releasing position. In other words, the first fixing part, designed to hold the locking element, able to move between a releasing position in which the element does not fix the movable element, and a locking position in which this element captures the movable element is located n the one end of the processing cartridge. The upper surface of the protruding part 141 runs as part 141b, designed to adjust the position of the cartridge when it is installed in the main unit And the devices. In addition, the housing 118 of the drum is provided with a protrusion 142, going down. The protrusion 142 operates as the second contacting part of the processing cartridge, which comes in contact with the movable element of the main unit And devices (to be described later), and, in addition, acts as the second locking part, which is intended for fixing the rolling element in the opening position.

(4) the Mechanism of protection of the electrical contacts on the side of the main unit of the device

Next will be described the construction of the electrophotographic device, the image corresponding to the present invention.

11 - Pig represent the General views of the main unit electrophotographic devices create images that demonstrate its design. Figure 11(a) shows the main unit of the device in which the cartridge is not yet installed, while figure 11(b) shows the main unit of the device containing the cartridge, while the cartridge itself is not shown. If we refer to 11(a), the main unit And the device is equipped with guides 130L1 and 130L2 to facilitate installation of the cartridge In this unit. In addition, the main unit And the device is provided with: a fixing spring 143, intended for fixation of the cartridge after it is installed in the position of the image creation; contact 144 grounding which is in contact with the shaft 139 of the drum (Figure 10) for grounding the photosensitive drum 107; a movable element 162 protecting electrical contact capable of moving between a protecting position in which it closes an electrical contact 161 of the transfer bias voltage for development (11(b)), which is one of the electrical contacts on the side of the main unit, and an opening position in which it leaves the electrical contact 161 of the transfer bias voltage for developing open; and the locking element 163, which is designed for fixing rolling element 162.

On the electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit, the voltage for development is supplied from a power source (not shown) using a predetermined control scheme in time.

Further, the design of the rolling element 162 and the locking element 163 will be described in more detail. As shown in Fig, the movable element 162 can be rotated is mounted on a shaft a impact spring in the direction of rotation in protecting the position shown in 11(a). The axis of rotation of the rolling stock is of lament 162 parallel to the axial line of the photosensitive drum 107, located in the cartridge, and a movable element capable as a result of rotation to move relative to the main unit And the devices. With regard to the movement of the rolling element 162 in the opening position (11(b)), in which he maintains electrical contact 161 of the transfer bias voltage for developing open, the movable element 162 is moved to this position when you insert the cartridge into the main unit And the devices. If you describe in more detail what will be re-done later, during insertion of the cartridge into the main unit And the device, the protrusion 142 (Figure 10)that serves as a second contact part of the cartridge that comes in contact with the contacting part 162b, which is part of the rolling element 162 (Fig). When installing the cartridge In the position to create the image projection 142 that serves as the second contact part is pressed against the rolling element 162 on the surface s, locking the movable element 162 in the opening position (11(b)). In the electrical contact 161 of the transfer bias voltage for development is opened and remains open through the slot 162d of the rolling element 162. Inner plate 145 has a small hole a, through which lies partially locking element 163 intended for fixation of the rolling element 162 (11(a)). The protrusion 142 operates not only as the pout contact part, but also as the first fixing part.

Fig is an image of the same parts of the device, images that are shown figure 11, except that Pig they are shown from a direction opposite that shown figure 11. As shown in Fig(a), the locking element 163 is installed to rotate on an axis a. As shown in Fig, between the surface 163b locking element 163 not shown inner plate 145 is elastic element 164 that serves as a first elastic member, the elastic element 164 acts on the locking element 163 in the direction indicated by the arrow A. Therefore, as will be clear from Fig(b), the contacting part is locking element 163 moves smoothly under the lower side of the rolling element 162, preventing the rotation of this element in the opening position.

(5) a description of the operation of the mechanism of protection of electrical contacts

Next will be described the mechanism of protection of electrical contacts. Fig - Fig represent the image that is used to describe the operation of the mechanism of protection of electrical contacts during insertion (promotion) of the cartridge In the main unit And the device.

Fig(a), Fig(a) and Fig(a) are views of a mechanism for protecting the electrical contacts on the side of the cartridge compartment 130 is, if you look in the direction of the inner plate 145 (in the direction of the arrow Y shown in 11(a)), Fig(b), Fig(b) and Fig(b)are views of a mechanism for the protection of electrical contacts, when viewed in the direction indicated by the arrow Z on Fig(a), Fig(a) and Fig(a). On Fig(a), Fig(a) and Fig(a) the contour of the cartridge shown in broken lines to facilitate understanding. In addition, to show the electrical contact 161 of the transfer bias voltage for development, part of the rolling element 162 is not shown.

Electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit is mounted on a shaft 166, which allows him to turn. Namely, when the cartridge is installed in the main unit And the device, the axis of rotation electrical contact 161 of the transfer bias voltage for developing parallel to the axial line of the photosensitive drum 107 In the cartridge, and this contact can be rotated relative to the main unit And the device.

In addition, if we consider the direction parallel to the axial line of the photosensitive drum 107, the movable element 162 and the electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit can be overlaid with other the other.

On Fig(a) and Fig(b) shows the state of the protection mechanism of the electrical contacts during installation of the cartridge into the main unit And the devices. The movable element 162 is in the position in which it closes an electrical contact 161 of the transfer bias voltage for development, and the locking element 163 is in the position in which it holds the movable element 162. The movable element 162 effect of the elastic element 165, serving the second elastic element, in the direction of the arrow b (Fig(a)). As described above, the locking element 163 in the direction of the arrow a, the effect of the elastic element 164 (Fig(b)). Therefore, the contacting part is locking element 163 passes into the compartment 130A of the cartridge through the hole in the inner plate 145, as shown in Fig(b), resulting in smooth movement under the lower side of the rolling element 162, and prevents its rotation. In addition, the protrusion 163d locking element 163 passes into the compartment 130A of the cartridge. In other words, when the locking element 163 is in the locking position, it prevents the movement of the rolling element 162 of defending in the opening position.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge pushed into the main unit of the device deeper. is in a condition shown respectively Fig(a) and Fig(b). These drawings depicted the moment when the protrusion 142 that serves as a second contact part of the cartridge that came into contact with the contacting part 162b of the rolling element 162 of the main unit And devices (Fig(a)). In this state, the protrusion 163d locking element 163 has come in contact with the contacting part 140L1a (serving as the first contact part), that is, with the portion of the guide element 140L1 cartridge, which comes in contact with the contacting part of the locking element 163 and turns on his axis a in the direction indicated by the arrow C, and the locking element 163 is moved to the release position (Fig(b)). When the locking element 163 is in the releasing position, the contacting portion s locking element 163 is deduced from the position in which it prevents rotation of the rolling element 162. Thus, the movable element 162 receives the opportunity to turn around. In other words, when the locking element 163 is in the releasing position, it allows the rolling element 162 to rotate. The resilient member 164 is in a compressed state.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge pushed even further into the main unit And the device on which ogene, shown respectively Fig(a) and Fig(b). The locking element 163 is held in the same position, which is shown in Fig(a) and Fig(b), by means of a set of edges 140L1b passing in the radial direction from the Central circular region of the guide element 140L1 cartridge to the periphery of this element. As for rolling element 162, it affects the ledge 142, causing it to rotate on an axis a in the direction indicated by the arrow d, the opposite action of the elastic force of the elastic element 165.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge is set to create the image. In this state, the guide 140L1 cartridge is in contact with the positioning part 130L1a guide 130L1, positioned on the side of the main unit, while the mentioned guide element is accurately positioned relative to the main unit And the devices. As for the upper part of the guide element 140L1 cartridge, it is in contact with locking spring 143, and as a result he pressed this spring down. The locking element 163 is held by means of the contact part a, serving as the first fixing part protruding part 141 (Figure 10) of the cartridge C. in Addition, the movable element 162 is fixed by means of the protrusion 142, sluzhashih the second fixing part, in the opening position, in which it keeps open the electrical contact 161 of the transfer bias voltage for development. When the cartridge is installed in this position, the workspace a electrical contact 161 transfer bias voltage to the developer comes in contact with the working area 160A electrical contact 160 receiving the bias voltage for development, ensuring that the electrical connection between the power source located on the side of the main unit And the device, and the cartridge C. the Operation of creating an image is carried out when the cartridge is in this state.

In General, the use of this variant of implementation of the present invention can provide the following benefits :

1. Even if the operator reaches through into the main unit And the device image, to fix a paper jam or similar problem after removing a processing cartridge from the main unit And the device image, access to electrical contact 161 located on the side of the main unit, it will be difficult, because the electrical contact 161 is not inside the main unit And the devices. Therefore will not deteriorate the electrical connection between the process cartridge and the main unit And devices by plastering is of human sweat and/or grease, available in the main unit And devices on the electrical contact 161.

2. The movable element of protection electrical contact moves when you move the cartridge, eliminating the need for the operator to perform a special operation for establishing electrical connection between the cartridge and the main unit And the device.

3. The main unit And the device equipped with a fixing element 163, designed to prevent the movement of the rolling element 162 in the opening position, in which the movable element 162 maintains the electrical contact of the main unit And the device open when the cartridge is not in the main unit And the devices. In other words, the operator can touch the electrical contact 161 of the main unit And the device, the movable element 162 should be moved to a position opening the electrical contact, while fixing the locking element 163 in the releasing position. Therefore, even if the operator reaches through into the main unit And device to carry out a maintenance device of an image, for example, to clear a paper jam or similar problem, the hand of the operator with significantly less likely to accidentally touch the electrical contact 161 in comparison with the case where the operator pushes ru is in the main unit of the device image, corresponding to the existing level of technology.

4. Surface a, serving as the first fixing part, is an area protruding part 141 of the guiding element 140L1 cartridge, which, in turn, is the item designed for accurate positioning of the cartridge C. Therefore, the position of the surface a stable, and thus, this surface works reliably.

5. The movable element 162 is moved by means of the protrusion 142, coming down from the cartridge in a position in which the movable element 162 maintains electrical contact located on the side of the main unit open, while the locking element 163 is fixed with one end surface of the cartridge C. Therefore, during insertion of the cartridge Into the locking element 163 is held in the position in which it does not fix the movable element 162, until the end of insertion of the cartridge into the main unit And the devices. Thus, it is guaranteed that the movable element 162 is moved to the opening position in which it keeps open the electrical contact on the side of the main unit.

6. The main unit And the device and the cartridge are so designed that, when the cartridge is in the main unit And the device, the axis of rotation of the rolling element 162 is parallel to the axial line of the photosensitive bar the ban 107, and the movable element 162 can be rotated relative to the main unit And the device; and that, when the cartridge is in the main unit And the device, the axis of rotation electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit parallel to the axial line of the photosensitive drum 107, and the electrical contact 161 of the transfer bias voltage for development is rotated relative to the main unit And the device; and that, when the movable element 162 and the electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts of the main unit And overlap each other, when viewed in a direction parallel to the above-mentioned centerline, which contributes to space saving.

Option 2

Next will be described the second embodiment of the present invention. The device 100 to generate an image in this embodiment is similar to the design of the device, the image corresponding to the first implementation variant of the present invention described above. So here we will only describe the design features that differ from the design features of the device, the image corresponding to the first implementation variant of the present from which retene. In addition, parts of the device of creating images in this version, which is identical in design and functionality to its precise copies from the first embodiments of the present invention, will be denoted by the same reference numbers, and will therefore be possible to link to mentioned an exact copy of the first embodiments of the present invention.

(1) the design of the main unit and cartridge

On Fig - Fig shows the locking element and the movable element of the main unit And the devices that are appropriate for implementation variant of the present invention.

On Fig(a) shows the compartment of the cartridge in the main unit And the device, in which there is no cartridge In, and Fig(b) shows the compartment of the cartridge in the main unit And the device containing the cartridge, the cartridge itself is not shown. When the cartridge is not in the main unit And the device, as shown in Fig(a), the electrical contact 161 of the transfer bias voltage for development is closed movable element 162, at the same time, when the cartridge is in the main unit And the device, as shown in Fig(b), the electrical contact 161 of the transfer bias voltage for development is open: it is not closed movable element 162.

Like the main unit And the devices in the first variant real is ment of the present invention, described with reference figure 11(a) and 11(b), the main unit And the device in this embodiment is also provided with electrical contact 161 of the transfer bias voltage for development; a movable element 162, designed to close an electrical contact 161 transfer bias voltage to the developer; and a fixation element 163, intended for fixing the rolling element 162.

This option differs from the first variant implementation of the present invention that the main unit And the device according to this variant is also equipped with a releasing element 200, which moves together with the movable element 162 and the locking element 163. When the main unit While the device is in the state shown in Fig(a), the release element 200 remains allocated to the groove in the guide 130L1 of the main unit And the devices. In addition, this variant differs from the first variant implementation of the present invention in a constructive plan by way of fixing the rolling element 162 of the locking element 163. These differences will be described in detail.

Fig is a General view of the compartment of the cartridge in the main unit And the device, when viewed in the direction indicated by the arrow Y2 in Fig. The locking element 163, shown in Fig set can be rotated like fixed is the overarching element in the first embodiment implementing the present invention. The basis unit And the device in this embodiment, furthermore, provided with a connecting element 201 and the elastic element 202. Connecting element 201 connects the liberating element 200 shown in Fig(a) and Fig(b), and the movable element 162.

Fig is a General view of the spatial separation of the parts, showing the liberating element 200 and the movable element 162, and associated parts, and which shows the design of these elements. Guide 130L1 of the main unit is equipped with axis 130L1 intended for installation liberating element 200 can be rotated. The liberating element 200 is equipped axis 200A, which is a hole a connecting element 201, creating support for the connecting element 201, allowing him to turn around. In addition, one end of the elastic element 202 geared shaft 200A liberating element 200 and the other end of the elastic element 202 geared for axis a (Fig), coming from the interior of the plate 145. Further, the connecting element 201 has a hole 201b, which includes the axis of the 162d of the rolling element 162, creating, thus, a support for the connecting element 201, allowing him to turn around. The connection releasing element 200 and the rolling element 162 makes possible the implementation of the above-described constructive solutions.

Fig represents is the overall view of the cartridge, corresponding to this implementation variant of the present invention. Like the cartridge in the first embodiment implementing the present invention, the cartridge in this embodiment also contains a guide 140L1 cartridge and the first contact part 140L1, which is part of the mentioned guide element, and the protrusion 142, coming down from the housing 119 of the drum. However, the protruding portion 141 is the speed (it has two sections: section a level surface with the same level guide element 140L1 cartridge, and the section surface a located at a closer level to the base of the cartridge). Therefore, the surface a guide element 140L1 cartridge, that is, the surface section, moved closer to the body of the cartridge does not perform the function of fixing the locking element 163 in the releasing position. This is a difference compared with the first variant of realization of the present invention.

(2) a description of the operation of the mechanism of protection of electrical contacts

Next will be described the operation of the protection mechanism of electrical contacts in this embodiment implementing the present invention. Fig - Fig are schematic image showing the mechanism of protection of electrical contacts when inserting it (promotion) of the cartridge In the main unit And the device.

Fig(a) - Fig(a) are views of a mechanism for the protection of electrical contacts, when viewed in the direction indicated by the arrow Y on Fig(a). Fig(b) - Fig(b) are views of a mechanism for the protection of electrical contacts, when viewed in the direction indicated by the arrow Y2 in 18(a). Fig(s) - Fig(C) are views of a mechanism for the protection of electrical contacts, when viewed in the direction indicated by the arrow Z2 in Fig(b). These images are shown to facilitate understanding of how the locking element 163.

On Fig(a) - Fig(C) shows the state of the protection mechanism of electrical contacts at various stages of insertion of the cartridge into the main unit And the devices. On Fig(a) a movable element 162 is in the protective position in which it closes an electrical contact 161 of the transfer bias voltage for development, and the locking element 163 is in the locking position, in which it fixes the movable element 162. When the locking element 163 is in the locking position, it prevents the movement of the rolling element 162 of defending in the opening position. On the locking element 163 in the direction of the arrow a, the effect of the elastic element 164. The locking part is locking element 163 is not directly captures the movable element 162; fixing the hour is ü s fixes the connecting element 201, connected to rotate with the movable element 162. As for liberating element 200, as shown in Fig(b), he turned on the axis 130L1 in the clockwise direction (the direction indicated by the arrow e), and allotted to the groove in the guide 130L1 of the main unit And the devices. Elastic element 202 is in such condition that its elasticity it affects the liberating element 200, tending to rotate it in the direction indicated by the arrow E.

On Fig(a) - Fig(C) shows the state of the protection mechanism of electrical contacts when the cartridge pushed deeper into the main unit And the device compared to Fig. In this state, the contacting portion 140L1, serving as the first contact part of the cartridge that came into contact with the tab 163d locking element 163 and turned the locking element 163 on the axis a in the direction indicated by the arrow from moving, thus, the locking element 163 in the release position as shown in Fig(C). When the locking member is in the releasing position, the locking part C this element is derived from the position in which it prevents movement of the connecting element 201. Therefore, the movable element 162 has the ability to turn. At this stage, however, the movable element 162 has not come in contact with the protrusion 142 on the body bar the ban, as shown Fig(a). Therefore, the release element 200 and the connecting element 201 remain in the same position in which they are shown in Fig (Fig(b)).

On Fig(a) - Fig(C) shows the state of the protection mechanism of electrical contacts on the stage, when the cartridge pushed deeper into the main unit And the device, compared with Fig. At this stage, the protrusion 142 provided on the body of the drum, came into contact with the contacting part 162d of the rolling element 162, as shown in Fig(a), providing, thus, the impact on the movable element 162, which causes it to rotate in the direction indicated by the arrow d. When the movable element 162 is rotated, the connecting element 201 is moved, as shown in Fig(b). Moving the connecting element 201 causes the rotation of the releasing element 200 on the axis 130L1 in the direction of the arrow f. As a result, the releasing element 200 protrudes from the notch in the guide 130L1 of the main unit And the device, as shown in Fig(a). In addition, the movement of the connecting element 201 causes contact between the surface a this element and contacting the surface of the 163d locking element 163.

On Fig(a) - Fig(C) shows the state of the protection mechanism of electrical contacts on the stage, when the cartridge is in position with the building image. As shown in Fig(a), the movable element 162 is turned further in the direction of the arrow d from the position shown in Fig, thus opening the electrical contact 161 of the transfer bias voltage for development. When the cartridge is installed in this position, the workspace a electrical contact 161 of the transfer bias voltage for development and workspace 160A electrical contact 160 receiving the bias voltage for development has come in contact with each other, establishing electrical connection between the main unit And the device, and a cartridge Century, the Creation of images is carried out at this stage. As for liberating element 200, then he turned further in the direction of the arrow f, from the position depicted in Fig, in the position depicted in Fig. As shown in Fig(b), the rotation of the rolling element 162 causes further movement of the connecting element 201, causing displacement of the liberating element 200 in the position shown in the drawing. As a result, the axis 200A, which is geared elastic element 202, receives a position below the axis 130L1 turn liberating element 200, resulting in exposure to the elastic force from the elastic element 202 in such a direction that it causes the release element 200 to rotate in aims and, indicated by the arrow f. Therefore, in contrast to the behavior of the protrusion 142 provided on the body of the drum, corresponding to the first implementation variant of the present invention, in this embodiment implementation of the present invention, the protrusion 142 does not fix the movable element 162 through the contact part 162d, which is obvious from Fig(a). As shown in Fig(C), the surface of the 163d locking element 163 abuts against the surface a connecting element 201, which prevents rotation of the locking element 163 in the direction indicated by the arrow A. In other words, in this embodiment implementation of the present invention, the surface a (Fig), i.e. the region of the recess, the protruding portion 141 of the casing of the drum, is made in such a way that does not fix the locking element 163.

Fig(a) and Fig(b) are images illustrating the operation of the protection mechanism of electrical contacts when removing the cartridge from the main unit And the devices. As shown in Fig(a), when the cartridge is removed from the main unit And the device, guide 140L1 cartridge moves along the guide 130L1 of the main unit And the devices. As described above, the release element 200, which can be rotated installed on the guide 130L1 of the main unit And the device comes out of the notches in this guide. So when install the j In take out, guide 140L1 cartridge comes in contact with the liberating element 200, causing the rotation of this element in the direction of the arrow g. When the release element 200 is in the position shown in Fig(a), the movable element 162 is in the opening position, in which it keeps open the electrical contact 161 of the transfer bias voltage for development, and, in addition, the locking element 163 is held in the releasing position. At this stage, extract the relationship between the locking element 163 and a connecting element 201 is the same as shown Fig(b) and Fig(C). In other words, the surface of the 163d locking element 163 and the surface a connecting element 201 are in contact with each other, as shown in Fig(s).

On Fig(b) shows the state of the protection mechanism of electrical contacts when the release element 200 has come in contact with a guiding element 140L1 cartridge In and forcibly taken to the notch of the guide 130L1 of the main unit And the devices. The liberating element 200 turns (through connecting element 201, which was described earlier) movable element 162 in the direction indicated by the arrow b, causing the movable element 162 is moved in the protective position in which it closes an electrical contact 161 transfer voltage is of the offset for processing. When the release element 200 is moved to the position shown in Fig(b), the locking element 163 is moved to the locking position. At this stage the relationship between the locking element 163 and a connecting element 201 is the same as shown Fig(b) and Fig(C). In other words, the connecting element 201 is turned up, calling, thus, the output on its surface a from contact with the surface of the 163d locking element 163, as shown in Fig(C). In the fixing element 163 is rotated under the action of the elastic element 164 in the direction of the arrow a, causing the locking part C will prevent movement of the connecting element 201.

In General, the use of this variant of implementation of the present invention can provide the following benefits :

1. Even if the operator reaches through into the main unit And the device image, to fix a paper jam or similar problem after removing a processing cartridge from the main unit And the device image, access to electrical contact 161 located on the side of the main unit, it will be difficult, because the electrical contact 161 is not inside the main unit And the devices. Therefore will not deteriorate the electrical connection between the process cartridge and the main unit And the devices due to the buildup of human sweat and/or grease, available in the main unit And devices on the electrical contact 161.

2. The movable element of protection electrical contact moves when you move the cartridge, eliminating the need for the operator to perform a special operation for establishing electrical connection between the cartridge and the main unit And the device.

3. The main unit And the device equipped with a fixing element 163, designed to prevent the movement of the rolling element 162 in the opening position, in which the movable element 162 maintains the electrical contact of the main unit And the device open when the cartridge is not in the main unit And the devices. In other words, the operator can touch the electrical contact 161 of the main unit And the device, the movable element 162 should be moved to a position opening the electrical contact, while fixing the locking element 163 in the releasing position. Therefore, even if the operator reaches through into the main unit And device to carry out a maintenance device of an image, for example to fix a paper jam or similar problem, the hand of the operator with significantly less likely to accidentally touch the electrical contact 161 in comparison with the case where the operator pushes ru is in the main unit of the device image, corresponding to the existing level of technology.

4. The main unit And the device and the cartridge are so designed that, when the cartridge is in the main unit And the device, the axis of rotation of the rolling element 162 is parallel to the axial line of the photosensitive drum 107, and the movable element 162 can be rotated relative to the main unit And the device; and that when the cartridge is in the main unit And the device, the axis of rotation electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit parallel to the axial line of the photosensitive drum 107, and the electrical contact 161 of the transfer bias voltage for development is rotated relative to the main unit And devices; and that the movable element 162 and the electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts of the main unit And overlap each other when viewed in a direction parallel to the above-mentioned centerline, which contributes to space saving.

Option 3

Next will be described the third embodiment of the present invention. The device 100 to generate an image in this embodiment is similar to the design of the device, the image corresponding to the first and second implementation variant of the present invention, described above. So here we will only describe the design features that differ from the design features of the device, the image corresponding to the previous variants of implementation of the present invention. In addition, parts of the device of creating images in this version, which is identical in design and functionality to its exact copies of the preceding variants of realization of the present invention, will be denoted by the same reference numbers, and will therefore be possible to link to the description mentioned the exact copies from the first and second variants of realization of the present invention.

Fig is a schematic cross-section of the device 100 to generate an image corresponding to this implementation variant of the present invention. It shows the same view of the device 100 to generate an image, as for devices produce an image corresponding to the first and second variants of implementation of the present invention (as viewed in the direction indicated by the arrow Y on Fig(a)).

The cartridge is inserted into the main unit And the device, while its guide 140L1 installed on the guide 130L1 of this block. On Fig(a) shows the state of the protection mechanism of electrical contacts at an early stage of the process arose and cartridge on which the movable element 162 is in the protective position in which it closes an electrical contact 161 of the transfer bias voltage for development and fixed locking element 163; fixing part is locking element 163 prevents the rotation of the rolling element 162 in the direction indicated by the arrow d. On the locking element 163 effect of the elastic element 203, tending to rotate on an axis 204 in the direction indicated by the arrow h. In addition, the movable element 162 effect of the elastic element 165, tending to rotate it in the direction indicated by the arrow b.

On Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge is moved into position to create the image. When the cartridge has been moved into the position of creating images thereon, the protrusion 142 came into contact with the contacting part of the 163d locking element 163, which led to the rotation of the locking element 163 in the direction indicated by the arrow i. When the cartridge is in position to create the image (Fig(b)), the contacting part of the 163d and the protrusion 142 remain in contact with each other. In other words, in this embodiment implementation of the present invention, the protrusion 142 performs the functions of the first contacting portion and the first fixing part.

When the locking element 163 povorachivaetsa is in the direction indicated by the arrow i, it releases the movable element 162 and the locking portion 205 of the cartridge comes in contact with the surface s rolling element 162, locking, thus, the movable element 162. In other words, the contacting portion 205 performs the functions of the second contact part and the second fixing part, and the surface s rolling element 162 is the surface by which the movable element 162 is fixed to the second fixing part. Shortly before the cartridge was installed in this position, the workspace a electrical contact 161 transfer bias voltage to the developer came into contact with working part 160A electrical contact 160 receiving the bias voltage for development, and thereby, the electrical connection between the main unit And the device, and a cartridge Century creation of the image is performed in this state. When the cartridge is removed from the main unit And the device, the movable element 162 and the locking element 163 is returned to the position shown Fig(a); a movable element 162 and the locking element 163 return, respectively, in protecting and locking position.

Fig is part of a General view showing the state of rolling element 162 and the locking element 163, when the cartridge is put in and create the image. When the cartridge is in position to generate the image thereon, the protrusion 142 is in contact with the contacting part of the 163d locking element 163, locking, thus, the locking element 163 of using the aforementioned contact portion 163d. In addition, the contacting portion 205 of the cartridge is in contact with the surface s rolling element 162, locking, thus, the movable element 162 by using the surface s. In this state, the electrical contact 161 of the transfer bias voltage for development and the electrical contact 160 receiving the bias voltage for development are in contact with each other, supporting, thus, the electrical connection between the main unit And the device, and a cartridge Century

When using the above constructive solutions provide advantages similar to the second variant of realization of the present invention.

1. Even if the operator reaches through into the main unit And the device image, to fix a paper jam or similar problem after removing a processing cartridge from the main unit And the device image, access to electrical contact 161 located on the side of the main unit, it will be difficult, because the electrical contact 161 is not inside the main b the eye And the device. Therefore will not deteriorate the electrical connection between the process cartridge and the main unit And the devices due to the buildup of human sweat and/or grease is present in the main unit And devices on the electrical contact 161.

2. The movable element of protection electrical contact moves when you move the cartridge, eliminating the need for the operator to perform a special operation for establishing electrical connection between the cartridge and the main unit And the device.

3. The main unit And the device equipped with a fixing element 163, designed to prevent the movement of the rolling element 162 in the opening position, in which the movable element 162 maintains the electrical contact of the main unit And the device open when the cartridge is not in the main unit And the devices. In other words, the operator can touch the electrical contact 161 of the main unit And the device, the movable element 162 should be moved to a position opening the electrical contact, while fixing the locking element 163 in the releasing position. Therefore, even if the operator reaches through into the main unit And device to carry out a maintenance device of an image, for example to eliminate C is Matie paper or a similar problem, the hand of the operator with significantly less likely to accidentally touch the electrical contact 161 in comparison with the case where the operator reaches through into the main unit of the device, the image corresponding to the existing level of technology.

4. The main unit And the device and the cartridge are so designed that, when the cartridge is in the main unit And the device, the axis of rotation of the rolling element 162 is parallel to the axial line of the photosensitive drum 107, and the movable element 162 can be rotated relative to the main unit And the device; and that, when the cartridge is in the main unit And the device, the axis of rotation electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts on the side of the main unit parallel to the axial line of the photosensitive drum 107, and the electrical contact 161 of the transfer bias voltage for development is rotated relative to the main unit And the device; and that the movable element 162 and the electrical contact 161 of the transfer bias voltage for development, which is one of the electrical contacts of the main unit And overlap each other when viewed in a direction parallel to the above-mentioned centerline, which contributes to space saving.

Option 4

Next is written to the fourth embodiment of the present invention.

(Overall construction of the electrophotographic device, image creation and design of a processing cartridge)

First, with reference to Fig and Fig will be described the General design of the electrophotographic device to create an image that uses a processing cartridge, which is installed with the possibility of removal in the main unit of this device, as well as the design of the above-mentioned cartridge.

Fig is a schematic cross-section of the electrophotographic device of the image (which in this implementation of the present invention is a laser printer), demonstrating its General design, and Fig is a schematic cross section of a processing cartridge, which is installed with the possibility of removal in the main unit of the above mentioned device, the image showing the General construction of the cartridge and the electrical contacts.

First, with reference to Fig will be described the General design of the device image from the point of view of the movement in the main unit of the device of the sheet of recording media S. Laser printer E creates the image using one of the electrophotographic ways of creating images. The sheet of recording media S TransportRule means of pumping and transporting the recording media into a tool for creating images, and image consisting of toner transferred on said sheet of recording medium S. Then, the sheet of recording medium S is transported in a means of fastening in which the image of the toner is fixed. After that, the sheet of recording medium S is discharged into the receiving tray. More specifically, in the lower part of the main unit of the device, image cartridge is installed 111, which is stored in the stack of multiple sheets of the recording medium S. the Sheets of the recording media S stored in the cassette 111 zone 1 feed recording media sequentially pulled out from the cassette 111 in-feed roller 112, starting with the topmost sheet, and sent to the zone 2 create an image by using a pair of conveying rollers 113 and a pair of conveying rollers 114. In zone 2 the creation of the image side surface of the photosensitive drum 151, rotating in the clockwise direction, the laser scanner 121 is projected beam of laser radiation modulated data to generate the image. As a result, the side surface of the photosensitive drum 151 creates a latent electrostatic image. This latent electrostatic image is manifested by means of the toner in the area of processing available in the manufacturing cartridge P; it proablems is in the image, formed of toner (which below will be referred to simply as the image of the toner). This image of the toner is transferred, as a loose image, the roller 124 of the transfer sheet of the recording medium S. Then, the sheet of recording medium S is sent to the zone 3 fastening through which it moves. During the movement of the sheet of recording medium S through the zone 3 pinning an image from a toner is fixed on the sheet. After that, the sheet of recording medium S is transported on and unloaded from the main unit of the device image by using a pair of discharging rollers 133. Reference number 4 marked area of electrical equipment that contains a power source and a control circuit designed to control the operation of the device image.

As for the process of recording information on both sides of a sheet of recording media S, then, after the sheet of recording medium S, on the front side of which the image has passed through the zone 3 fixing, he goes back with a pair of transporting/discharging rollers 133, the direction of rotation is reversed, and the pair of conveying rollers 131, and then is transported via a pair of conveying rollers 141 and a pair of lines is chirouse rollers 142 re-zone image creation. Then the image is created on the reverse side of a sheet of the recording medium S. Then, the sheet of recording medium S is discharged from the device creating the image.

As for the manufacturing of the cartridge P, then, as shown in Fig, the photosensitive drum 151 is rotated, and as the rotation of its side surface is uniformly charged by a voltage applied to the roller 152 charging, which means charging. The voltage applied to the roller 152 charging, is fed to it from the zone 4 electrical equipment, available in the main unit of the device through the electrical contact 125, located on the side of the main unit, and the electrical contact 153, located on the side of the cartridge. Further, by projecting the laser scanner 121 beam of laser radiation L, modulated data to generate the image on the lateral surface of the photosensitive drum 151, on this surface creates a latent image. This latent image is developed in the tool developer that uses toner.

If we describe this in more detail, the roller 152 charging is in contact with the photosensitive drum 151 and charges the drum. The roller 152 charging is rotated by rotation of the photosensitive drum 151. Tool development manifests the latent image created attacullaculla drum 151 by feeding toner to the portion of the lateral surface of the photosensitive drum 151, in the zone boundary.

The processing means sends the toner contained in the container 154 of toner in the chamber 156 processing using a rotating mixing element 155. It also causes the rotation of the roller 157 processing, hosting the magnetic roller (permanent magnet), and creates a layer of a charged due to friction of the toner on the lateral surface of the roller 157 processing by using a metering blade 158. In the means of developing the latent image present on the photosensitive drum 157, when a voltage is applied to the roller 157 development is manifested in the transfer of the toner located on the lateral surface of the roller, on the side surface of the photosensitive drum 151 in accordance with the pattern of the latent image. In the means of developing the latent image becomes visible, namely, in the image consisting of toner. With regard to the supply voltage to the roller 157 processing, then this voltage is applied from the zone 4 electrical equipment, available in the main unit of the device on the roller 157 processing through the electrical contact 126 of the transfer bias voltage for development, located on the side of the main unit, and the electrical contact 158, located on the side of the processing cartridge. The metering blade 158 not only regulates the amount of toner on the lateral surface of the roller 157 processing, but that the same charges the toner, located on the lateral surface of the roller 157 processing, due to friction.

After the image transfer of the toner to the sheet of the recording material S by means of the roller 124 of the transfer of the photosensitive drum 151 is cleaned by means of cleaning the remaining toner on it. Then clean the part of the lateral surface of the photosensitive drum 151 is used to continue the process of creating images. The cleaning tool clears away the toner remaining on the side surface of the photosensitive drum 151 by using to the included elastic squeegee 159 in contact with a lateral surface of the photosensitive drum 151, and collects cleared the toner in the hopper 160 toner bottle.

The processing cartridge P is equipped with an electronic tag 6 (microchip with a receiver containing information about the device operation), which is the means of storing information, which is installed on the surface of the processing cartridge P. the Electronic tag 6 gets the opportunity to exchange information with the main unit as a result of establishing electrical connections with electrical contact 71, available in the connector 7, located in the main unit.

Reference number 161 marked the shutter drum. When handling the cartridge is outside of the main unit of the device, the shutter 161 Baraba is and is held in position, in which it closes the opening in the processing cartridge P, which is partially visible to the photosensitive drum 151 to protect the drum. When handling the cartridge in the main unit of the device, the shutter 161 drum is moved to the open position and locked into position, opening the photosensitive drum 151 in the lower pane, as shown in Fig and Fig.

Next will be described the case of the manufacturing of the cartridge P. As shown in Fig, the photosensitive drum 151, the roller 152 charging, the cleanup tool, for example an elastic squeegee 159 or the like, attached to the body 162 of the drum, i.e. to one of the housing parts of the manufacturing of the cartridge P, the components of the node of the photosensitive element. The node processing means consists of a container 154 toner roller 157 processing, metering blade 158 and the housing 164 to install the processor, is attached to these components. The site of the photosensitive element and node processing means are connected to each other by means of connecting rods, allowing them to rotate relative to each other. In other words, the processing cartridge consists of a node of the photosensitive element and node processing means.

(Constructive solution for the installation and removal of the processing cartridge compartment and clicks the processing cartridge)

Next, with reference to Fig - Fig will be described in the design guide elements intended for installation and removal of the processing cartridge P, and the processing compartment of the cartridge. Fig is a General view of the main unit of the device of the image (in which the access door print cartridge is opened for installation or removal of the processing cartridge), showing its General structure. Fig and Fig represent General types of processing compartment of the cartridge, available in the main unit of the device, showing the installation tool (removal) processing cartridge located in the main unit of the device. Fig and Fig represent General types of processing cartridge.

First will be described guiding elements, or similar means, which is provided with the cartridge. Machining ka is the drier cartridge P is provided with a pair of guide elements 190 and 191 (Fig and Fig), which have in particular its part of a cylindrical shape, protrude from the end surfaces of the processing cartridge and have the same location. In addition, the processing cartridge P is provided with protrusions 191 and 193 control of rotation, which is also located on the end surfaces of the cartridge P in the same way and have such an arrangement that, when handling the cartridge P is installed in the main unit of the device, they are on the upper edge of the end surface of the cartridge.

Next will be described guiding elements, which is provided with the main unit of the device. Main unit E devices are keyed 181-189 (Fig and Fig). Guiding elements 181 and 186 have a slope corresponding to an insertion direction of the processing cartridge P into the main unit of the device, and pass respectively into the guide portion 185 and 189. When handling the cartridge P is inserted into the main unit E device guide members 192 and 190 of the cartridge is in contact with the guide elements 181 and 186, respectively. Guide members 183, 182 and 187 also have a inclination in the direction of the installation processing of the cartridge P into the main unit of the device. When handling the cartridge P is inserted into the main unit of the device, the protrusions 191 and 193 control rotation includes the contact with the guide elements 183, 182 and 187, respectively. The shutter 161 drum opens or closes when the cylindrical element 197 (Fig) is moved along the guide elements 182 and 184 of the main unit of the device.

The contact portion 194 and a retaining portion 195 of the manufacturing of the cartridge P, which will be described later in more detail, perform the function of movement, respectively, the locking element and the moving element of the main unit of the device.

(The design of the protection mechanism of electrical contacts)

Next will be described the electrical contacts of the main unit electrophotographic device image creation and design of the mechanism of protection of electrical contacts. Fig - Fig represent the General views of different parts of the main unit electrophotographic devices create images that demonstrate its design. They depict what it looks like inside the compartment of the cartridge, available in the main unit of the device, if you look through the hole, through which handles the cartridge P is mounted or removed. Fig is a General view of the compartment of the cartridge when handling the cartridge is missing, and Fig is a General view of the cartridge compartment, which has a processing cartridge P, although the cartridge itself is not shown. As can be seen from f g, the main unit of the device is equipped with guide rails 186 and 187, serving to facilitate installation of the manufacturing of the cartridge P. the Main unit of the device is also equipped with a locking spring 188, which is designed for fixing and processing cartridge P in place after it is installed in the main unit of the device, and the contact 201 of the ground, which comes in contact with the shaft 196 of the drum (Fig) for grounding the photosensitive drum 151. In addition, the main unit of the device includes: a movable element 202, capable of moving between a protecting position in which it closes the electrical contact 126 of the transfer bias voltage for development (Fig shown by dashed line), which is one of the electrical contacts located on the side of the main unit, and an opening position (Fig), in which he reveals mentioned electrical contact 126; the locking element 203 (Fig)intended for fixing the rolling element 202; and a conductive element 204 attached to the rolling element 202 and able to move with him.

Conductive element 204 is in the vicinity of the electrical contact 126. It is located in the compartment of the cartridge, available in the main unit of the device.

In addition, the main unit of the device is provided with a bottom rail 205 tra is spartanovka and the upper rail 206 transportation (contour delineated by dashed lines on Fig and Fig), which are part of the path of feed of the recording media. These guides 205 and 206 are always in a grounded state, as well as inner plate 207, which is deeper relative to the electrical contact 126 when viewed in the compartment of the cartridge through the hole in the main unit of the device.

Next will be described the construction of the rolling element 202, conductive element 204 and the locking element 203. As shown in Fig, the movable element 202 mounted to rotate on an axis a, and it affects the spring tends to turn it into a protecting position shown in Fig. Conductive element 204 is attached to the rolling element 202. All that is needed to move the moving element 202 and conductive element 204 in the opening position (Fig), in which the movable element 202 opens the electrical contact 126 is setting a processing cartridge P into the main unit of the device. As for the installation process of the manufacturing of the cartridge P into the main unit of the device, which will be described later again, then, during the installation of the processing cartridge P into the main unit of the device, the contact portion 194 (Fig) cartridge P is in contact with the contacting part 202b, which is part of the rolling element 202 (Fig). When installing the cartridge P in the position of creating images of the contacting portion 194 (Fig) cartridge P is in contact with the surface zone s rolling element 202, locking, thus, the movable element 202 and the conductive element 204 in the opening position (Fig), in which the movable element 202 opens the electrical contact 126 through existing item slot 202d. Inner plate 207 has a hole 207a through which the contact portion 203b locking element 203, designed to secure the rolling element 202, has the ability to partially extend into the compartment of the cartridge (Fig). Fig is a General view of the mechanism of protection of electrical contacts, when viewed in the opposite direction, is shown in Fig. As shown in Fig(a), the locking element 203 can be rotated is mounted on a shaft a and in the direction indicated by the arrow a, the effect of the elastic element (not shown)located between the locking element 203 and the inner plate 207. Therefore, the contact portion 203b locking element 203 involuntarily moves smoothly under the lower side of the rolling element 202, preventing, thus, the rotation of this element in the opening position, which is clearly shown in Fig(b).

(the Scripture of the construction and operation of mechanism for protecting the electrical contacts)

Next will be described the mechanism of protection of electrical contacts. Fig - Fig are schematic image intended to describe the operation of the mechanism of protection of electrical contacts when inserting it (promotion) of the cartridge P into the main unit of the device.

Fig(a), Fig(a), Fig(a) and Fig(a) are views of a mechanism for the protection of electrical contacts and related parts, if viewed from the side guide elements 181 and 182 of the main unit of the device in the direction of the inner plate 207 (in the direction indicated by the arrow Y on Fig). Fig(b), Fig(b), Fig(b) and Fig(b) are views of the same areas, as shown on Fig(a), Fig(a), Fig(a) and Fig(a), when viewed in the direction indicated by the arrow Z. In Fig(a), Fig(a), Fig(a) and Fig(a) the contour of the cartridge P is shown in broken lines to facilitate understanding. In addition, to show the electrical contact 126 of the transfer bias voltage for development, part of the rolling element 202 and a portion of the conductive element 204 is not shown. Next, Fig(b) - Fig(b) electrically conductive element 204 hatched to facilitate understanding. The electrical contact 126 of the transfer bias voltage for development is mounted on a shaft 208, which allows him to turn.

On Fig(a) and Fig(b) shows the state of the mechanism is and protection of electrical contacts and the surrounding elements before or during installation of the cartridge P into the main unit of the device. The movable element 202 and the conductive element 204 are in the position in which they close the electrical contact 126 of the transfer bias voltage for development, and the locking element 203 is in the position in which it fixes the movable element 202. The elastic part a conductive element 204 is pressed to the boarding area 205A of this element, located on the bottom of the guide 205 transporting, providing, thus, the grounding conductive element 204. When the elastic bending of the elastic part a occurs a predetermined amount of pressure in the contact. The movable element 202 in the direction indicated by the arrow b, the effect of the elastic element 209. As described above, the locking element 203 in the direction indicated by the arrow a, the effect of the elastic element (not shown). In the contact part is locking element 203 is in the compartment of the cartridge through the hole 207a in the inner plate 207, as shown in Fig, smoothly moving under the bottom side of the rolling element 202, preventing, thus, the rotation of the rolling element 202 and conductive element 204.

When using the above design, if the hand of the user, the accumulated static electricity before inserting the cartridge P is close to electric is ntact 126, static electricity from your hands is discharged to the conductive element 204 and, therefore, will not discharge to the electrical contact 126.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge P is pushed deeper into the main unit of the device from the positions shown, respectively, on Fig(a) and Fig(b). These drawings depicted the moment when the contact portion 194 of the cartridge P just come into contact with the contacting part 202b of the rolling element 202, located in the main unit E unit (Fig(a)). In this state, representing the projection of the contacting part is locking element 203 has come in contact with the acting side surface of the guide element 190. In the fixing element 203 is turned on the axis a in the direction indicated by the arrow from moving, thus releasing position (Fig(b)). When the locking element 203 is in the releasing position, its contact portion 203b deduced from the position in which it prevents rotation of the rolling element 202. Therefore, the movable element 202 receives the opportunity to turn around. In other words, when the locking member is in the releasing position, it allows the rolling element 202 to rotate. The elastic element is, designed to exert pressure on the locking element 203 is in a compressed state.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts and the surrounding elements, when the cartridge P is pushed even further into the main unit of the device from the positions shown, respectively, on Fig(a) and Fig(b). The locking element 203 is held in the same position, which is shown in Fig(a) and Fig(b), by using the side surface of the guide element 190 of the cartridge P. as for the rolling element 202, then he pressed the contacting part 194, turning in the direction of the arrow d on the axis a against the elastic force acting from the side of the elastic element 209.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge P is set to create the image. In this state, the guide element 190 is in contact with the positioning part 189 of the guide region of the main unit of the device, with the guide element 190 accurately positioned relative to the main unit of the device. As for the upper area of the guide element 190, it is in contact with locking spring 188, which presses it down. The locking element 203 is kept locking part 195 (Fig) card is IgA R due to the contact with the contacting part s. In addition, the movable element 202 and the conductive element 204 fixed contact part 194 in the opening position, in which they retain the electrical contact 126 open. When the cartridge P is mounted in this position, the elastic part a conductive element 204 is separated from the landing area 205A of this element, located on the bottom of the guide 205 of transportation, which breaks the contact conductive element 204 to ground. In addition, the electrical contact 126 of the transfer bias voltage to the developer comes in contact with electrical contact 158 receiving the bias voltage for development, providing electrical connection between the main unit of the device and the cartridge P. the Operation of creating an image is performed when the cartridge P is in this state. When there is electrical connection between the electrical contact 126 of the transfer bias voltage for development and electrical contact 158 receiving the bias voltage for development, located on the side of the cartridge P from the power source located on the side of the main unit is supplied with a high voltage level which is several thousand volts. Although the electrical contact 126 of the transfer bias voltage for development and conductive element 204 is located near the Rog to each other, it is guaranteed that the conductive element 204 remains electrically isolated from the lower guide 205 transfer, which is grounded.

In General, the use of this variant of implementation of the present invention can provide the following benefits :

1. If the user looks into the cartridge compartment on the device image creation, standing in the position in which it establishes a processing cartridge into the main unit of the device when handling the cartridge is not in the main unit of the device image, the electrical contact 126 is directly behind the electrically conductive element 204. Thus, even if the hand of the user has static electricity, when he sticks his hand in the region of the main unit of the device, the image next to the electrical contact 126 to clear a paper jam or similar problem after removing a processing cartridge P from the main unit of the device, the image mentioned static electricity is discharged to the conductive element 204. Therefore, electrostatic interference does not fall on the electrical contact 126 of the main unit of the device image. Therefore, the elements of the electric circuit is not subjected to the Xia static electricity.

2. When handling the cartridge is in the main unit of the device image, the electrically conductive element 204 is not grounded, being completely electrically isolated from the grounded parts. Thus, the processing cartridge and the device generate an image corresponding to this implementation variant of the present invention, surpass handles the cartridge and the device generate an image corresponding to the existing level of technology, from the point of view of reliability of connection between the electrical contact of the main unit of the device and electrical contact processing cartridge, and reliability in the supply of electricity from the electrical contact of the main unit of the device to the electrical contact of the processing cartridge.

3. Conductive element moves when you move a processing cartridge, which occur when installing or removing. Therefore, the user does not need to perform a special operation to move the conductive element.

Fig and Fig are diagrams showing the operation of the protection mechanism of electrical contacts when inserting it (promotion) of the cartridge P into the main unit of the device.

Fig(a) and Fig(a) are views of a mechanism for the protection of electrical contacts and related parts, if viewed from the side guide elements 181 and 182 of the main unit of the device in the direction of the inner plate 207 (in the direction indicated by the arrow Y on Fig). Fig(b) and Fig(b) are views of the same areas, as shown on Fig(a) and Fig(a), when viewed in the direction indicated by the arrow Z. In Fig(a) and Fig(a) the contour of the cartridge P is shown in broken lines to facilitate understanding. In addition, to show the electrical contact 126 of the transfer bias voltage for development, part of the rolling e is ment 202 and part of the twisted region of the electrical contact 126 is not shown. The electrical contact 126 of the transfer bias voltage for development is mounted on a shaft 208, which allows him to turn. Connecting the contact spring 210 is connected to the 4-zone electric equipment (not shown).

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts and the space surrounding it before or during installation of the cartridge P into the main unit of the device. The movable element 202 is in the position corresponding to its position before inserting the cartridge and the locking element 203 is in the locking position, in which it fixes the movable element 202. The grounding part a and the connecting portion 126b of the electrical contact 126 are held hook part a rolling element 202. Elastic element 209 acts on the movable element 202 in the direction indicated by the arrow b. Therefore, the grounding part a electrical contact 126 is pressed to the region 205A bottom rail 205 transportation, providing grounding electrical contact 126. As described above, the locking element 203 in the direction indicated by the arrow a, the effect of the elastic element (not shown). Therefore, the contacting part is locking element 203 is in the compartment of the cartridge through the hole in the inner plate 207, as shown in Fig, moving smoothly under the lower is the thoron rolling element 202, preventing, thus, the rotation of the rolling element 202 and conductive element 204.

When using the above design, if the hand of the user, the accumulated static electricity before inserting the cartridge P is in the vicinity of the electrical contact 126, and static electricity from your hands is discharged, it is discharged to ground and, therefore, will not discharge in zone 4 electrical equipment.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge P is set to create the image. Movement of the rolling element 202 and the locking element 203 that happened up to this point during insertion of the cartridge P, is identical to the displacements that occurred during the insertion of the cartridge P in the fourth implementation of the present invention, and therefore will not be described. In this state, the guide element 190 is in contact with the positioning part 189 of the guiding element of the main unit of the device, with the guide element 190 accurately positioned relative to the main unit of the device. As for the upper area of the guide element 190, it is in contact with locking spring 188, which presses it down. The locking element 203 is kept locking part 195 (Fig) CT the ridge R due to the contact with the contacting part s. In addition, a grounding part a and the connecting portion 126b of the electrical contact 126 is separated (breaking electrical connections) from the hook part a rolling element 202. When the cartridge P is mounted in this position, the grounding part a electrical contact 126 away from the region 205A bottom rail 205 transportation, breaking the connection with the earth. In addition, the connecting portion 126b of the electrical contact 126 is in contact with the connecting part 210A connecting the contact spring 210. Also, when moving the cartridge P in this position the electrical contact 126 of the transfer bias voltage to the developer comes in contact with electrical contact 158 of the cartridge P, and the connecting portion 126b of the electrical contact 126 is in contact with the connecting part 210A connecting the contact spring 210, providing electrical connection between the main unit of the device and the cartridge P. the Operation of creating an image is performed when the cartridge P is in this state. When there is electrical connection between the electrical contact 126 of the transfer bias voltage for development and electrical contact 158 of the cartridge P, is supplied to the high voltage level which is several thousand volts. However, the grounding part a electric to the of ntact 126 guaranteed is not in contact with the region 205A (which is grounded) bottom rail 205 transportation. As a result, the use of this alternative implementation of the present invention provides the following advantages.

1. If the user sticks his hand in the area in the vicinity of the electrical contact 126 in the main unit of the device image, to fix a paper jam or a similar problem, and the hand has accumulated static electricity, the static noise fall on the electrical contact 126 of the main unit of the device. However, when the main unit of the device, the image does not appear machining cartridge electrical contact 126 is grounded. Therefore, static noise not included in an electric circuit. Therefore, static noise does not affect the electrical circuit.

2. When handling the cartridge in the main unit of the device, the electrical contact 126 is in contact with the connecting pin spring 210, resulting in the connection zone 4 electrical equipment, available in the main unit of the device. In addition, interrupts the connection of the electrical contact 126 to ground, providing electrical isolation from grounded parts. Thus, the processing cartridge and the device generate an image corresponding to this implementation variant of the present invention, exceed rabatyvaemy the cartridge and the device image creation relevant existing level of technology, from the point of view of reliability of connection between the electrical contact of the main unit of the device and electrical contact processing cartridge, and reliability in the supply of electricity from the electrical contact of the main unit of the device to the electrical contact of the processing cartridge.

Option 6

Next will be described a sixth embodiment of the present invention. Items used in this embodiment, which are similar in design and functionality of the parts used in the fourth embodiment of implementation of the present invention, will be denoted by reference numbers that are identical to those used in the description of the fourth embodiments of the present invention, and will not be described. In other words, this embodiment of the present invention will be described only from the point of view distinguish his features.

(Description of the construction and operation of mechanism for protecting the electrical contacts)

Next will be described the construction of the mechanism of protection of electrical contacts, corresponding to this implementation variant of the present invention. Fig and Fig are schematic image showing the mechanism of protection of electrical contacts when inserting it (promotion) of the cartridge P into the main unit of the device.

Fig(a) and Fig(a) are views of a mechanism for the protection of electrical contacts and related parts, if viewed from the side guide elements 181 and 182 of the main unit of the device in the direction of the inner plate 207 (in the direction indicated by the arrow Y on Fig). Fig(b) and Fig(b) are views of the same areas, as shown on Fig(a) and Fig(a), when viewed in the direction indicated by the arrow Z. In Fig(a) and Fig(a) the contour of the cartridge P is shown in broken lines to facilitate understanding. The electrical contact 126 of the transfer bias voltage for development is mounted on a shaft 208, which allows him to turn. Connecting the contact spring 210 is connected to the 4-zone electric equipment (not shown).

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts and the space surrounding it before or during installation of the cartridge P into the main unit of the device. The movable element 202 is in the position corresponding to its position before inserting the cartridge and the locking element 203 náchod is conducted in the locking position, in which he fixes the movable element 202. The connecting portion 210A connecting the contact spring 210 is held hook part a rolling element 202. Elastic element 209 acts on the movable element 202 in the direction indicated by the arrow b. Therefore, the connecting portion 210A connecting the contact spring 210 is held at a distance from the connecting part 126b of the electrical contact 126, while maintaining electrical contact 126 in a floating state from the point of view of establishing the electrical connection. As described above, the locking element 203 in the direction indicated by the arrow a, the effect of the elastic element (not shown). Therefore, the contacting part is locking element 203 is in the compartment of the cartridge through the hole in the inner plate 207, as shown in Fig, smoothly moving under the bottom side of the rolling element 202, preventing, thus, the rotation of the rolling element 202 and conductive element 204.

When using the above design, when the main unit of the device, the cartridge P is absent, the electrical contact 126 "floats" from the point of view of establishing the electrical connection. Therefore, even if the hand of the user, the accumulated static electricity before inserting the cartridge P is close to electrical con the act 126, static electricity from your hands will not discharge at the contact and, therefore, does not fall within zone 4 electrical equipment.

On Fig(a) and Fig(b) shows the state of the protection mechanism of electrical contacts when the cartridge P is set to create the image. Movement of the rolling element 202 and the locking element 203 that happened up to this point during insertion of the cartridge P, is identical to the displacements that occurred during the insertion of the cartridge P in the fourth implementation of the present invention, and therefore will not be described. In this state, the guide element 190 is in contact with the positioning part 189 of the guiding element of the main unit of the device, with the guide element 190 accurately positioned relative to the main unit of the device. As for the upper area of the guide element 190, it is in contact with locking spring 188, which presses it down. The locking element 203 is kept locking part 195 (Fig) cartridge P by contact with its contact part SS. In addition, the connecting portion 210A connecting the contact spring 210 is separated from the hook portion a rolling element 202. When the above-mentioned separation of the connecting portion 126b of the electrical contact 126 is in contact with the connecting part 210A connect the enforcement of the contact spring 210. When the cartridge P is mounted in this position, the connecting portion 126b of the electrical contact 126 is in contact with the connecting part 210A connecting the contact spring 210. In addition, when moving the cartridge P in this position the electrical contact 126 of the transfer bias voltage to the developer comes in contact with electrical contact 158 of the cartridge P, and the connecting portion 126b of the electrical contact 126 is in contact with the connecting part 210A connecting the contact spring 210, providing electrical connection between the main unit of the device and the cartridge P. the Operation of creating an image is performed when the cartridge P is in this state. When there is electrical connection between the electrical contact 126 of the transfer bias voltage for development and electrical contact 158 of the cartridge P, is supplied to the high voltage level which is several thousand volts. In the time of high voltage in the vicinity of the electrical contact 126 no grounded parts.

As a result, the use of this alternative implementation of the present invention provides the following advantages.

1. When in the main unit of the device, the image does not appear machining cartridge electrical contact 126 "floats" from the point of view created what I electrical connection. Therefore, even if the user sticks his hand in the area in the vicinity of the electrical contact 126 in the main unit of the device image, to fix a paper jam or a similar problem, and the hand has accumulated static electricity, the static noise does not fall on the electrical contact 126 of the main unit of the device. Therefore, static noise not included in an electric circuit. Therefore, static noise do not affect the elements of the electrical circuit.

2. When handling the cartridge in the main unit of the device, the electrical contact 126 is in contact with the connecting pin spring 210, resulting in the connection zone 4 electrical equipment, available in the main unit of the device. Thus, the processing cartridge and the device generate an image corresponding to this implementation variant of the present invention, surpass handles the cartridge and the device generate an image corresponding to the existing level of technology, from the point of view of reliability of connection between the electrical contact of the main unit of the device and electrical contact processing cartridge, and reliability when power is applied.

3. Electrical connection is switched when moving about rabatyvayuschego cartridge what is happening when installing or removing. Therefore, the user does not need to perform a special operation for switching the electrical connection.

Above first to sixth implementations of the present invention have been described with respect to electrical contacts serving to supply the bias voltage used during developing. However, it is obvious that the present invention is also applicable to electrical contacts in the processing cartridge and the main unit of the device image that is different from the contacts used when applying a bias voltage for development, such as electrical contacts for supplying the bias voltage for charging the electrical contacts of the memory (storage element), etc.

In addition, the above the embodiments of the present invention have been described with reference to a laser printer as an example of the electrophotographic device of the image. However, it is obvious that the above-described constructive solution corresponding to the present invention can also be applied to the device to create an image that is different from a laser printer that forms an image on a recording medium such as paper to write, OHP-film (OHP, OverHead Projector - slide projector, otherwise diaprojektor film), fabric, etc. using one of the electrophotographic ways of creating images, for example, in electrophotographic copying machine, electrophotographic printer (for example, led printer, a laser printer and so on), electrophotographic facsimile machine, an electrophotographic office system, word processing, etc.

According to the above invention, it is possible to improve the processing cartridge and electrophotographic device to generate the image from the point of view of reliability of electrical connections that occur between the electrical contacts of the manufacturing of the cartridge and the electrical contacts of the main unit electrophotographic device to generate the image when the processing cartridge in the main unit electrophotographic device to create the image.

Also, according to the present invention, even if the hand of the user has accumulated static electricity, when the user sticks his hand in the region close to the electrical contacts of the main unit electrophotographic device, the image is static electricity is discharged to the conductive element. Therefore, static electricity does not affect the electrical kontaktierung block. In addition, when the processing cartridge is in the main unit, electrically conductive element is not grounded. Therefore, the proposed processing cartridge and the main unit exceeds the processing cartridge and the base unit corresponding to the known prior art, from the point of view of reliability of electrical connection between the electrical contacts of the main unit and the electrical contacts of the processing cartridge designed for the supply of electricity in the manufacturing cartridge from the main unit of the device. Further, the conductive element moves when moving the processing cartridge that occur when installing or removing. Therefore, the user does not need to perform a special operation to move the conductive element.

Further, the possibility of establishing electrical connection with electrical contacts of the main unit of the device to power supply appears only when processing the print cartridge is installed in the main unit of the device, which improves the characteristics of the device image from the point of view of reliability of electrical connection between the process cartridge and the main unit. In addition, when moving a processing cartridge, which occur when installing or removing the going is it switching the electrical connection. Therefore, the user does not need to perform a special operation for switching the electrical connection.
