The cartridge for supplying toner

Next, with reference to Figure 2(a)-2(c) will be described cassette 1 for supplying toner as a cassette for feeding the developer with reference to its construction.

The body 1a of the cassette 1 for supplying toner, which is the actual part of the contents of the cassette 1 for supplying toner is in the form of an approximately hollow cylinder. The cylindrical part of the housing 1a of the cassette is made with a hole 1b as an outlet for toner, which approximately represents a long and narrow rectangle, the long edges of which are parallel to the longitudinal direction of the cassette 1.

If the cartridge 1 for supplying toner was never used, the hole 1b are sealed with the seal 9 is formed from a film (which will hereinafter be called the sealing film 9). The sealing film 9 is two times longer than the length of the hole 1b. The sealing film 9 is welded to the housing 1a of the cassette from one end of the hole to the other in the longitudinal direction of the cassette 1 for supplying toner to seal holes 1b, bent in the opposite direction to the initial end and is held at the initial end. The sealing film 9 must be removed by the user after installation of the cassette 1 for supplying toner in the device 7 for receiving toner, which will be described n the same when the user pulls the sealing film 9 by means of capturing part of the sealing film 9, which passes out for a specified initial end of the sealing film 9, and the hole 1b is opened.

In this regard, the sealing film 9 in this embodiment is designed so that it must be removed from the casing 1a of the cassette to open the hole 1b. However, the sealing film 9 may be performed as follows.

For example, the sealing film 9 can be performed with a pair of detachable guide (tear line) so that, when the sealing film 9 is pulled, it will easily come off along a pair of detachable guide. These tear-guides can be formed by thinning the sealing film 9 along pre-defined lines on the sealing film 9 by means of influence on the part of the sealing film 9, which correspond to pre-defined lines, with a laser beam. The method of refining the sealing film 9 along predefined lines may be a method other than the method based on the laser.

The sealing film 9 is provided to prevent leakage of toner from a cartridge for supplying the developer when a cassette for feeding the developer. More specifically, the sealing film 9 is provided to prevent leakage of the toner is from a cassette for feeding the developer, when there are some changes in the environment of the cassette for feeding the developer (changes in temperature, humidity and atmospheric pressure) during placement of the cassette for feeding the developer. In addition, the sealing film 9 prevents leakage of toner from a cartridge for feeding the developer by vibration of the cassette for feeding the developer, which occurs during placement of the cassette for feeding the developer, and/or impacts that may occur if the cassette for feeding the developer accidentally fall during installation.

However, even if the casing of the cartridge is sealed with the sealing film 9, can sometimes leak of toner, for example, if changes in the environment of the cassette for feeding the developer that occur during placement of the cassette for feeding the developer, rather large and/or shocks that occur as a result of the fall of the cassette for feeding the developer in the cartridge for supplying the developer, strong.

Thus, the purpose of the sealing film 9 in this embodiment is to prevent toner leakage reasonable changes in the environment of the cassette for feeding the developer, which may occur when placing the cassette for feeding the developer. In other words, in the following description of the preferred options implemented the program of the present invention to prevent leakage of toner means to prevent leakage of toner reasonable changes in the environment of the cassette for feeding the developer, which may occur during placement of the cassette for feeding the developer.

As the method of fixing the sealing film 9 on the housing 1a of the cassette can be used a method of welding that uses a hot plate, pulse, ultrasonic waves or high frequency waves, a method of bonding, which uses a conventional adhesive or a hot melt adhesive, the method that uses double-sided adhesive tape and the like. In this embodiment, the applied method, which uses a hot plate.

Cassette 1 for supplying toner is made with the sealing element 10, which is elastic element 10 (elastic seal)fixed on the housing 1a of the tape around the hole 1b. The sealing element 10 is provided to almost completely prevent the passage of toner in the gap between the cassette 1 for supplying toner and a device 7 for receiving the toner when the toner is supplied from the cassette 1 for supplying toner in the device 7 for receiving toner. More specifically, the sealing element 10 remains compressed to a preset value between the casing 1a of the cartridge and the shutter of the cartridge. Thus, it prevents the passage of the toner in this gap by closing the gap between the cassette 1 for supplying toner and a device 7 for the reception that the EPA. In this regard, preventing the passage of toner means not only complete prevention of the passage of the toner, and the passage of the toner in this gap in the number, which is almost too small to cause unwanted effects.

In addition, the sealing element 10 is an element that performs its function after removal of the sealing film 9. For optimal filling of the gap between the cartridge to supply toner, and a device 7 for receiving toner, it must be placed on the edge of the hole 1b, so that the sealing element 10 is fixed on the housing 1a of the cassette.

Therefore, it is necessary that before the fastening of the sealing film 9 on the housing 1a of the cassette sealing element 10 was fixed to the body 1a of the cassette, and then was assigned to the sealing film 9 on the housing 1a of the cassette to close the sealing element 10 and its border areas, as shown in figure 2(c).

Thus, in this embodiment, the portion 9a of the sealing film 9, with which the sealing film 9 is welded to the housing 1a of the cassette is designed so that when the sealing film 9 is welded to the housing 1a of the cassette, the part 9a of the sealing film 9 surrounds the sealing element 10. The use of the above structural scheme can prevent damaged the e of the sealing element 10 when removing the sealing film 9. That is, it can prevent the reduction of its sealing efficiency of the specified gap, when the toner is supplied from the cassette 1 for supplying toner in the device 7 for receiving toner. In addition, the sealing film 9 also performs the function of protecting the surface of the sealing element 10. That is, in the case of the above described structural diagrams in this embodiment, the sealing film 9 can prevent damage to the sealing element 10 before the first use of the cassette 1 for supplying toner to supply the toner in the device 7 for receiving toner.

Taking into account the presence of pressure in the friction between the sealing element 10 and the wall of the device 7 for receiving toner, it is necessary that the material for the sealing element 10 had a low density. More specifically, can be used foamed substance, such as polyurethane foam, high-density, woven or non-woven fabric on the basis of animal fibers such as wool or silk, vegetable fibers, such as cotton or flax, or synthetic fibers such as nylon, polyester, acrylic. As a material for the sealing element 10 from the viewpoint of the ability to choose compression foam substance. In this embodiment, as a material for the sealing element 10 is used polyurethane high density improvement is I.

As shown in figure 2(a), the cassette 1 for supplying toner is provided with the shutter 3 of the cassette, the curvature of which corresponds to the curvature of the peripheral surface of the housing 1a of the cassette 1 for supplying toner and which is attached to the cassette 1 for supplying toner so that it can close the opening 1b. Before removing the sealing film 9 sealing film 9 remains closed by the shutter 3 tapes. The shutter 3 of the cartridge engages with the pair of guide elements 1d, which are located on the longitudinal ends of the casing 1a of the cassette, one guide element 1d on one end. Cassette 1 for supplying toner is designed so that the shutter 3 cassettes can slide in the circumferential direction of the casing 1a of the cassette on the peripheral surface of the housing 1a of the cassette.

One of the end walls of the casing 1a of the cassette relative to the longitudinal direction of the housing 1a of the cassette is made with a hole 1c as the inlet for the toner, which is sealed with a cover not shown), or similar, after filling of the cassette 1 for supplying toner cartridge.

In addition, the cassette 1 for supplying toner is provided with a handle 2 as hand grip, which is designed to be gripped by the user when installing or removing a cassette 1 for supplying toner. The handle 2 is fixed on one of the longitudinal ends of the cartridge 1 for supplying toner. The stick form is 2 need not be limited to the form, presented in this embodiment. That is, Pets any form as long as she gives the possibility to use the handle for installation or removal of the cassette 1 for supplying toner, and also to rotate the cassette 1 for supplying toner.

The body 1a of the cassette is provided with a conveying element 4, which is located in the cavity of the housing 1a of the cassette. This transporting element 4 consists of a rotational shaft and stirring blades. The axial line of the rotational shaft coincides with the line connection, which will be described below. Mixing blades fixed on the rotational shaft. Mixing blades perform the function of transferring the toner from the housing 1a of the cassette to the hole 1b and the function of mixing the toner.

In addition, the cassette 1 for supplying toner is provided with a connecting flange 5, which is located on the longitudinal end of the housing 1a of the cassette opposite the end on which the handle 2. Flange 5 is connected to the conveying element 4 so that the rotation of the connecting flange 5, rotates the conveying element 4. In this embodiment, the rotational shaft of the conveying element 4 and flange 5 are molded from the polymer as a whole.

Flange 5 is arranged to mesh with unite is part of the mechanism of the primary node device 100. The main unit and cassette 1 for supplying toner is designed so that when the attachment to the flange 5 of the rotational force, the toner can be discharged from the cassette 1 for supplying toner installed in the main unit of the image formation.

When the rotational force is transferred to the conveying element 4 through a connecting flange 5, the transporting element 4 rotates relative to the cassette 1 for supplying toner, which is actually mounted stationary on the primary node device. As a result, the toner out of the cartridge 1 for supplying toner is transferred under stirring conveying element 4 to the hole 1b and then discharged through an opening 1b.

In this regard, the cassette 1 for supplying toner does not need to be mounted stationary on the primary node device. That is, it doesn't matter as long as the principal unit and cassette 1 for supplying toner is designed so that the main node devices, at least, prevents rotation of the cartridge 1 for supplying toner to the rotation of the conveying element 4 in the same direction in which the rotating conveying element 4.

A device for receiving toner

Then, with reference to Figure 3(a)-3(c) will be described device 7 for receiving toner as a device for receiving the developer n the side of the main unit of the image formation.

The device 7 for receiving the toner is provided with a compartment 7a (space for maintenance), in which the cassette 1 for supplying toner installed with the possibility of removal, and the hole 7b for receiving the cartridge, through which the toner discharged from the cassette 1 for supplying toner is supplied into the main unit of the image formation.

The device 7 for receiving toner is also provided with a shutter 8 devices, which can be re-sealed or open hole 7b for receiving toner. The curvature of the shutter 8 of the device corresponds to the curvature of the peripheral surface of the cassette 1 for supplying toner to the curvature of the wall of the compartment 7a of the cartridge to supply toner. It is connected with a guiding element (not shown)located on the bottom edge of the space 7a of the cartridge to supply toner. Using the above-described structural schema provides a sliding shutter 8 device in the direction along the circumference of the branch 7a of the cartridge for supplying toner to open or close the holes 7b for receiving toner (Figure 3(b) 3(c)).

As shown in Figure 3(b), when the cassette 1 for supplying toner is not in the branch 7a of the cartridge to supply toner, the edge area of the edge (the upper edge in figure 3(b)) of the shutter 8 of the device in contact with the stopper 7c, which is provided by the device 7 for receiving toner, thereby preventing the turn for the limiter 7c. That is, the hole 7b for receiving toner remains closed with the shutter 8 of the device, preventing the passage of toner back side of the main unit of the image formation in the side branch 7a of the cartridge to supply toner.

As shown in Figure 3(b) and 3(c), the shutter 8 of the device is also provided with a connecting part 8a, which is connected with the connecting part 6 of the cartridge 1 for supplying toner.

With regard to the connection parts 6 of the cartridge 1 for supplying toner from the connecting part 8a of the shutter 8 devices, the result of the rotation of the cassette 1 for supplying toner from the point of view of the direction along the circumference of the cassette 1 for supplying toner) from the position in the device 7 for receiving toner, which is installed in the cassette 1 for supplying toner, or from which the cassette 1 for supplying toner disconnected, respectively, in the feeding position of the toner, in which the cassette 1 for supplying toner is rotated by a predefined angle, the connecting part 6 of the cartridge 1 for supplying toner connected with the connecting part 8a of the shutter 8 of the device.

The operation for installing or removing a cartridge for supplying toner

Referring to Figure 4 and 5(a)-5(d), will be described the operation for installing the cassette 1 for supplying toner to the primary node device or removing it from the primary node device. Figure 5(b) and 5(a) depict views in enlarged scale of the edge sections of the holes 1b, shown in Figure 5(a) and Figure 5(c), respectively.

First of all, the user must hold the handle 2 and to insert the cartridge 1 for supplying toner in the device 7 for receiving toner. More specifically, the cassette 1 for supplying toner must be installed in the device 7 for receiving the toner in the direction indicated by the arrow A (Figure 4).

During installation of the cassette 1 for supplying toner in the device 7 for receiving toner hole 1b of the cassette 1 for supplying toner is facing up, remaining thickened sealing film 9, and the shutter 3 is in the closed position (Figure 5(b)).

That is, the hole 1b of the cassette 1 for supplying toner is in position, located at a distance from the hole 7b for receiving toner remaining thickened gate 8 devices, from the point of view of the direction of rotation of the cassette 1 for supplying toner. In addition, the connecting part 6 of the cartridge 1 for supplying toner is also in a position located at a distance from the connection part 8a of the shutter 8, from the point of view of the direction of rotation of the cassette 1 for supplying toner (Figure 5(a)).

Then, the user must pull out the protruding end portion of the sealing film 9 in the direction indicated by the arrow C (Figure 2(a)), for removal of the sealing film 9.

Then, the user must hold the handle 2 and to rotate the cassette 1 for supplying toner counterclockwise page is (X-direction figure 5(a)), as seen from the direction of the hole 1c as the inlet for toner.

In this regard, the cassette 1 for supplying toner to the primary node device is designed in such a way that, when the cassette 1 for supplying toner is rotated, the rotation of the shutter 3 cassettes in the circumferential direction of the cassette 1 for supplying toner is regulated by the stopper 7c.

That is, during the initial stage of rotation of the cassette 1 for supplying toner in the X-direction, the shutter 3, the cassette is moved from the cassette 1 for supplying toner. However, when the cassette 1 for supplying toner is additionally rotated in the X-direction, the shutter 3 of the cassette comes in contact with the specified stopper 7c, which prevents further rotation.

Then, when the cassette 1 for supplying toner is additionally rotated in the same direction, the connecting part 6 of the cartridge 1 for supplying toner engages with the connecting part 8a of the shutter 8 devices. Then, when the cassette 1 for supplying toner is rotated additionally, the shutter 8 of the device is shifted to the connecting part 6, thus, turning with a cassette 1 for supplying toner. As a result, the hole 7b for receiving toner offers. Hole 7b for receiving toner connects to the hole 1b (Figure 5(c) and 5(d)).

Cassette 1 for supplying toner to the primary node device is designed so that only when Artie 7b for receiving the toner is connected to the hole 1b, to the flange 5 applied force from the mechanism of connection on the side of the main unit of the image formation and the resulting force is transferred to the conveying element 4, thus providing a supply of toner in the device 7 for receiving toner from the cartridge 1 for supplying toner. In addition, when the hole 7b for receiving the toner is connected to the hole 1b, the gap between the cassette 1 for supplying toner and a wall of the device 7 for receiving the toner is filled in the sealing element 10, thus preventing the passage of toner from the hole 7b for receiving the toner and/or holes 1b in this gap.

After completing the application process for the toner, the user must hold the handle 2 and to rotate the cassette 1 for supplying toner in a clockwise direction (the Y direction in Figure 5(c)), as seen from the direction of the hole 1c as the inlet for the toner. During the initial stage of the rotation connecting part 8a of the shutter 8 of the device is still connected to the connecting part 6 of the cartridge 1 for supplying toner, thus moving upwards from the connecting part 6. Therefore, the connecting portion 8a is rotated with the cassette 1 for supplying toner.

When the cassette 1 for supplying toner is additionally rotated, the shutter 8 device comes into contact with the stopper 7c, thus, prevents the I further move with the cassette 1 for supplying toner. As a result, the connecting part 6 is detached from the connection part 8a of the shutter 8 of the device.

When the cassette 1 for supplying toner is additionally rotated, the hole 1b and the sealing element 10 is closed by the shutter 3 cassettes, which rotation is clockwise controlled by the unit 7 for receiving toner. Then, in the final stage of the clockwise rotation of the cassette 1 for supplying toner and mutual arrangement of these elements of the cassette 1 for supplying toner and a device 7 for receiving toner becomes as shown in Figure 5(a).

Finally, the user must remove the cassette 1 for supplying toner from the device 7 for receiving toner to complete the sequence of operations to re-seal the hole 7b for receiving the toner and hole 1b as an outlet for the toner and remove the cartridge 1 for supplying toner from the device 7 for receiving toner.

In this regard, in this embodiment, this is done from the front side of the main host device, when the cassette 1 for supplying toner is installed in the device 7 for receiving toner. However, the direction in which the cassette 1 for supplying toner is installed in the device 7 for receiving toner, need not necessarily be limited to the front side of the main unit. For example, the cassette 1 for supplying toner and core the main node device can be designed in such a way, the cassette 1 for supplying toner is installed in the device 7 for receiving toner or detached from it on the upper side of the main device node.

In addition, in this embodiment, the cassette 1 for supplying toner to the primary node device is designed in such a way that, when the hole 1b is turned in the horizontal direction, it connects with the hole 7b for receiving toner walls of the device 7 for receiving toner, the angular position of which relative to the vertical direction is approximately 90°. However, they do not necessarily need to be performed as in this embodiment.

In addition, the direction in which the cassette 1 for supplying toner turns when installing it in the device 7 for receiving toner, need not necessarily be limited to the specified direction. For example, the cassette 1 for supplying toner to the primary node device can be designed in such a way that the hole 1b is directed downwards, when the cassette 1 for supplying toner is installed in the device 7 for receiving the cartridge, and the cartridge 1 for supplying toner is rotated in the direction opposite to the direction in which the cassette 1 for supplying toner is rotated in this embodiment, with the purpose of opening, and is rotated in the opposite direction of this version of the OS is enforced, to re-seal.

In case of using this structural scheme of the toner is not out of the holes 1b during placement of the cassette 1 for supplying toner or in a similar situation. In addition, after a single sequence of installation of the cassette 1 for supplying toner in the device 7 for receiving toner and retrieve it from the device 7 for receiving toner, there was virtually no evidence for the contamination of the toner cartridge 1 for supplying toner and a device 7 for receiving toner. This situation persisted even after twenty-fold repetition of the same sequence.

As is clear from the description of this variant implementation, block diagram, this embodiment can prevent the contamination of the toner in the cartridge 1 for supplying toner, and when the supply of toner in the device 7 for receiving toner from the cartridge 1 for supplying toner. In other words, it can prevent contamination of the user's toner, which has stuck to the cassette 1 for supplying toner.

In this regard, in the above-described embodiment, the sealing element 10 fixed to the body 1a of the cassette 1 for supplying toner.

The second option exercise

With reference to 6 will be described cartridge for supplying toner of this variant implementation. The cartridge for supplying toner in this embodiment is of the same construction as the cartridge to supply toner in the above-described first embodiment, except for the parts of the cartridge to supply toner, which will be described below. In addition, elements, parts, etc. cartridge for supplying toner in this embodiment that performs the same function as in the first embodiment, are denoted by the same reference numbers used to describe the first version of the implementation, and will not be described in detail.

This preferred variant implementation differs from the first preferred variant of the implementation of that scheme for opening or closing the holes 1b differs from the scheme in the first embodiment. More specifically, as shown in Fig.6(a), the cartridge for supplying toner in this embodiment has a structure consisting of two cylinders: it contains the inner cylinder 300 as part of the content, which contains the toner, and the outer cylinder 400 (which hereinafter may be referred to as a gate), which is mounted for rotation around the DNAs is Rennie cylinder 300.

As shown in Fig.6(b), the inner cylinder 300 is made with a hole 1b, which is similar to the hole 1b in the first embodiment. The inner cylinder 300 is also provided with a sealing element 10, which is fixed on the inner cylinder 300 around the hole 1b as in the first embodiment. In addition, the inner cylinder 300 is provided with a sealing film 9, which is fixed on the inner cylinder 300 in such a way as to close the sealing element 10, as is done in the first embodiment.

In addition, the inner cylinder 300 is made with a connecting part 302, which engages with the connecting part of the device for receiving the toner to prevent additional rotation of the internal cylinder 300 after gearing connecting part 302 with the connection part of the device for receiving the toner. Peripheral surface of the inner cylinder 300 is made with guide 301.

As for the outer cylinder 400, it is provided with a connecting hole 401, which is performed with the opportunity to connect through hole 1b. In addition, the cylindrical wall of the outer cylinder 400 is provided with a guide slot 402 in which is inserted a guide 301 of the inner cylinder 300 in the direction of the guide slot 402, so about what atom, preventing displacement of the two cylinders 300 and 400 in a direction parallel to their axes of rotation when the outer cylinder 400 is rotated relative to the inner cylinder 300.

After installing the cartridge for supplying toner in the device for receiving toner hole 1b of the inner cylinder 300 is located at an angle of 90° relative to the connecting holes 401 of the outer cylinder 400 in the direction along the circumference of the cartridge to supply toner, and at this point, the operator must withdraw the sealing film 9.

After this, the operator must rotate the outer cylinder 400 by a predetermined angle (which in this embodiment is about 90°) in a preset direction indicated by the arrow, relative to the internal cylinder 300, which is still recorded by the device for receiving toner. Thus, during rotation of the outer cylinder 400, the hole 1b of the inner cylinder 300 is combined with the connecting hole 401 of the outer cylinder 400, i.e. the hole of the outer cylinder 400 and the bore of the inner cylinder 300 soy is yaytsa, providing a supply of toner from a cartridge to supply toner in the device for receiving toner.

As for sequence extraction cartridge for supplying toner from the device for receiving toner cartridge for supplying toner can be removed from the device for receiving the toner by performing in reverse order described above sequence of installation of the cassette for feeding the toner in the device for receiving toner. That is, the operator must rotate the outer cylinder 400 in the direction opposite the installation direction at a predetermined angle (which in this embodiment is about 90°) to close the hole 1b of the inner cylinder 300. When closing the holes for the operator, it becomes possible to eject cartridge for supplying toner from the device for receiving toner.

As described above, in this embodiment, the function performed by the shutter of the cartridge in the first embodiment, performs the outer cylinder 400. In addition, the shutter of the cartridge is opened in the rotation of the outer cylinder 400 instead of the rotation of the inner cylinder 300 as part of the content of toner.

The same effects as the effects obtained through structural diagram of the first preferred embodiment can also be obtained blah is odara the block diagram of this embodiment.

In this regard, in this embodiment, the sealing element 10 fixed to the inner cylinder. However, the sealing element 10 can be fixed on the inner surface of the outer cylinder. In this case, the sealing element 10 is fixed on the inner surface of the outer cylinder around the connecting holes. This structural scheme can also prevent the passage of toner in the space between the inner and outer cylinders similar to the block diagram of this embodiment. In addition, in this case, the sealing element 10 can be attached to the interior surface of the outer cylinder which surrounds the hole 1b of the inner cylinder when the hole 1b is closed outer cylinder, i.e. during the placement of a cartridge for supplying toner.

In addition, in the first and second preferred embodiments, the implementation described above, the housing of the cassette for feeding the developer was approximately cylindrical. It is understood that these embodiments of do not limit the scope of the present invention. That is, the form of a cassette for feeding the developer may be different in contrast to the form in the previous two variants of implementation up until this form provides the content of the developer in the cassette for feeding the developer. For example, the R, it may be polygonal in cross section.

In addition, in the first and second preferred embodiments, the implementation described above, the forming device of the image (the device for receiving the developer) in accordance with the present invention was a photocopier. However, the present invention is also applicable to the forming device of the image is different from the copy device.
