The technical field to which the invention relates.

The present invention mainly relates to imaging and, in particular, various aspects of the present invention relate to devices and methods for supplying the developer in the device forming images.

The level of technology

Device imaging, such as a printer, Photocopying machine, facsimile machine, multi-function external device or the like, are designed to print images using a developer. After repeated printing operations, the developer is consumed and need to be replenished.

For the replenishment of the developer showing the cartridge, where the developer must be replaced. However, showing the cartridge may also have other elements, such as showing the platen and/or the feed roller, which can have a relatively long lifetime. Therefore, the replacement of the developing cartridge in order to replenish the developer may be uneconomical.

Therefore, the inventors applicants simultaneously with this proposed split showing the cartridge with a removable cartridge to the developer, which allows to compensate for the developer by replacing only the removable cartridge to the developer. However, although a removable cartridge for PR is the revealer can reduce the need for unnecessary replacement of all developing cartridge, it may be necessary control over the supply of the developer from the removable cartridge to the developer in showing the cartridge, so as not to overload the last.

So, in the case of excess supply of the developer in showing the cartridge, the developer can Wake up and/or to leak from the developing cartridge and contaminate the elements of the device imaging and/or cause unwanted marks on the images on the print media. It is also possible that the excessive supply of developer pressure in showing the cartridge may increase, resulting in increased driving load required to actuate the elements of the developing cartridge, and this can even lead to mechanical damage to the feed mechanism of the developer device imaging.

Detailed description of several embodiments of the invention

Below is a description of embodiments of the present invention, examples of which are illustrated by the drawings, to which reference position everywhere refer to similar elements. The issues reflected in the description, such as detailed description of the structures, configurations, layouts and/or components thereof, set forth solely to facilitate understanding of embodiments, in practice, may not need all of the various aspects of the present invention. Thus, it should be evident that the concept of the invention can be implemented without the specific details described below. For purposes of brevity and to avoid congestion of presenting excessive details, well-known features and design elements are not described in detail.

Figure 1 shows the perspective view of the developing device 1, which can be used with the device forming the image of the clusters in accordance with the embodiment of the present invention. Figure 2 - section processing device 1, shown in figure 1, along the line 2-2. Figure 3 - section processing device 1, shown in figure 2, without a cartridge for the developer.

Processing device 1 (Fig 1-3) in accordance with the embodiment of the invention may be showing the cartridge 10, which may be removable cartridge to the developer.

Showing the cartridge 10 may have a body 11, a carrier 12 images, showing the platen 13, the storage compartment 20 of the developer and the mounting socket 30.

The housing 11 forms an external view showing the cartridge 10 and may hold the carrier 12 images and/or showing the platen 13. Foldable handle 19 may be located on the side of the housing 11. The handle 19 may be used when installing the developing cartridge 19 and its separation from the device imaging 100 (Fig).

In accordance with the embodiment of the invention, the carrier 12 images can be rotated in the housing 11, and a portion of the carrier 12 images can extend out of the housing 11 through the hole made in the casing 11. Next to the carrier 12 images can also be used to host device 16 cleaning media image, designed to remove the developer remaining on the carrier 12 images, and the charging roller 17, which is designed for charging the surface of the carrier 12 images. In this innovation is the embodiment, the carrier 12 images is showing the cartridge 10. But alternative media 12 images can be separated from the developing cartridge 10.

Showing the roller 13 rotates in the housing 11 near the carrier 12 images to supply the latest developer from the storage compartment 20 of the developer. Can also be applied to the roller 14 of the supply of the developer to transport developer to manifesting roller 13 from the storage compartment 20 of the developer.

Compartment 20 storage developer made in the housing 11 and is designed for storing a quantity of developer. In the storage compartment 20 of the developer can also accommodate one or more conveying elements 21 and 22 supply of the developer supplying and/or circulation of the developer located in the storage compartment 20 of the developer. In presented at the figure 4 embodiment of the invention in the storage compartment 20 of the developer there are two conveyor element 21 and 22 supply of the developer. But an alternative other layouts can be used any number of conveyor elements for conveying the developer. 4 is a partial perspective view of the housing 11 of the developing cartridge 10, made in accordance with the embodiment of the invention with two conveying elements 21 and 22 supply of the developer.

In submissions to the nom figure 5 embodiment of the invention, the transporting elements 21 and 22 supply the developer may have essentially the form of the screw. The blades 23 and the width can be cut in the axial direction of the screw. Cut space 24 of the conveyor elements 21 and 22 supply of the developer remaining after the formation of the blades 23 may limit the increase in the pressure inside the developing cartridge 10. Thus, when the pressure inside the developing cartridge 10 is partially increased, for example, due to partial adhesion of the developer, carved seat 24 of the conveyor elements 21 and 22 supply the developer can provide a relatively low pressure, so that the developer in the area of high pressure will have the opportunity to move to cut the seats 24 of the conveyor elements 21 and 22 feed the developer, reducing the pressure inside the developing cartridge. When the transporting elements 21 and 22 supply of the developer used screws with a partially cut by the blades 23, the amount of the developer in the storage compartment 20 of the developer can mainly be distributed uniformly in the axial direction of the conveying elements 21 and 22 supply of the developer. As a result of this can be reduced by changes in image density caused by a change in the amount of the developer in the axial direction of the conveying elements 21 and 22 supply of the developer. In the alternative in which the version of the invention the transporting elements 21 and 22 supply of the developer can be hollow worm form, a similar distribution supply element of the developer 53, described below.

As shown in figure 2 and 3, the housing 11 above the storage compartment 20 of the developer executed the inlet 20a. The developer supplied from the outlet 50a of the developer cartridge 50, passes through the inlet 20a, which may have different shapes. In the embodiment of the invention, presented in Fig.6, the inlet 20a has a generally hexagonal shape.

Above the entrance hole 20a can accommodate the connecting element 40. When the cartridge of the developer 59 is installed in showing the cartridge 10, the connecting member 40 provides compatibility of the outlet 50a of the developer cartridge 50 with the inlet 20a developing cartridge 10, allowing the developer to move between the cartridge to the developer and the developing cartridge 10. The connecting element 40 can be formed separately and installed at the inlet 20a. In the embodiment of the invention shown in figure 2 and 3, the connecting member 40 is made so that it acts and outputted from the inlet 20a of the housing 11. The inner part of the coupling element 40 is made to fit the shape of any one of the output apertures 50a of the developer cartridge 50 or the inlet 20a building the CA 11 of the developing cartridge 10. So, when the form of the cross section of the inlet 20a is mostly hexagonal (6), the internal cross section of the connecting element 40 in the form may be hexagonal corresponding to the shape of the cross section of the inlet 20a.

The connecting element 40 can have a predefined height H (7), such that when the of the developer cartridge 50 is mounted on showing the cartridge 10, the developer may flow back through the connecting element 40 in accordance with the pressure discharge in the output hole 50a of the developer cartridge 50 and the supply pressure in the inlet port 20a developing cartridge. In accordance with one embodiments of the invention, the maximum width W of the inlet 20a developing cartridge 10 may be greater than the height H of the connecting element 40. In the embodiment of the invention, the outlet 50a of the developer cartridge 50 may have the same shape as the inlet 20a developing cartridge 10, so that the height H of the connecting element 40 can also be less than the maximum width W of the outlet 50a of the developer cartridge 50.

In addition, in accordance with the embodiment of the invention, allowing to implement the above action, the area of the inner section A (the shaded area figure 6) connect inogo element 40 may be performed at least ten times greater height H of the connecting element 40. That is, the connecting member 40 is formed in accordance with the inequality A≥10×H. Taking into account the condition of the above inequality, while the common base unit of measurement, such as mm for linear measurements (for example, height H) and square millimeter to square A and so on, the dimension can be ignored and to consider only numeric values.

Thus, the inlet 20a developing cartridge 10 in accordance with the embodiment of the invention has the shape of a hexagon with a maximum width W approximately equal to 12 mm, the minimum width of the V is approximately equal to 8 mm, the cross-sectional area A is approximately 90 mm2. The height H of the connecting element 40 can be about 2-5 mm, Therefore, the maximum width W of the inlet 20a developing cartridge 10 is greater than the height H of the connecting element 40. The cross-sectional area A of the inlet 20a developing cartridge 10 is 90, and ten times the height H of the connecting element 20 will be approximately 20-50, i.e. compliance with the above inequality is satisfied.

Mounting slot 30 (Fig) in the housing 10 can be made in the form corresponding to the of the developer cartridge 50 so that the latter is removable manner is installed in the mounting slot 30 which may be located in pairs is lelno showing the platen 13. In the mounting socket 30 is at least one guide groove 31a and 31b, which of the developer cartridge is mounted in the mounting socket 30.

A of the developer cartridge 50 may also have at least one rail 59a and 59b corresponding to the at least one guide groove 31a and 31b made in the mounting socket 30. In the embodiment of the present invention (figure 2) on opposite sides of the mounting slots 30 made two slots 31a and 31b, which includes two guides 59a and 59b.

Element energy transfer (not shown)that transmits energy to the conveyor element 21 (22) or 53 of the discharge of the developer (figure 4 and 9), in the of the developer cartridge 50 may be placed in the lower part of the mounting socket 30. The connecting element 40 can be located on the surface of the mounting slots 30 next to the storage compartment 20 of the developer. When a of the developer cartridge 50 is mounted in the mounting slot 30 exit hole 50a, the specified cartridge can be mounted coaxially with the inlet 20a developing cartridge 10, providing a moving fluid.

A of the developer cartridge 50 (figures 9 and 10) can essentially be in the form of a rectangular parallelepiped. In the cartridge of the developer 50 is made of a receiving compartment 51 of the developer, where you can store the specified number is the primary objective of the developer. The transport element 53 of the discharge of the developer rotatably mounted in the receiving compartment 51 of the developer. If desired, the side of him, parallel to the receiving compartment 51 of the developer, can be installed in the compartment 52 of the collection of spent developer, where the carrier 12 images enters the spent developer removed by the device 16 cleaning the carrier 12 of the image.

In the lower part of the developer cartridge 50 is made the hole 50a. The developer located in the receiving compartment 51 of the developer, the transport element 53 of the discharge of the developer is moved to the outlet 50a through which falls out of the developer cartridge 50. The bottom surface of the receiving compartment 51 of the developer can be stepped (figure 10), i.e. the lower surface of the first portion 51a of the receiving compartment 51 which is closer to the inlet 50a, may be higher than the bottom surface of the second part 51b of the receiving compartment 51 for developer located farther from the outlet 50a, where essentially stores the developer. If the bottom surface of the first part 51a which the outlet 50a, is located above the lower surface of the second portion 51b that stores the developer, the pressure exerted by the developer stored in the receiving compartment 51 of the developer, to the outlet 50a can have anisou value.

The transport element 53 of the discharge of the developer (11) has an inlet 56 that moves the developer outlet hole 50a, and a return portion 57 through which the developer can move in a direction opposite to the feed direction, i.e. the direction of movement of the feeding portion 56 when the pressure near the outlet 50a of the cartridge of the developer increases. In this embodiment, the transport element 53 of the discharge of the developer is formed mainly by the hollow shape of the screw. The spiral blade of the auger is feeding part 56 that moves the developer outlet hole 50a, and the hollow portion of the screw corresponds to the return portion 57 through which the developer is moved from the outlet 50a in the direction opposite to the direction of discharge of the developer.

When in the receiving compartment 51 of the developer cartridge to the developer 50 is an excessive amount of the developer, it is moved to the outlet 50a under the action of axial forces of supply created hollow screw 53 (11 and arrow F1, Fig.9). When this hollow portion 57 of the screw 53 can create a relatively lower pressure than the other part. Thus, when the pressure of the developer near the outlet 50a (i.e. pressure discharge) increases and exceeds a certain value, despite the rotation of the screw is 53, the developer may terminate the movement in the direction F1, and accumulate in the hollow portion 57 of the screw 53, which is characterized by a relatively low pressure. If the pressure near the outlet 50a will continue to increase, the developer gathered in the hollow portion 57 of the screw 53 will be able to navigate through the hollow portion 57 in the direction opposite to the axial force of the feed screw 53 (arrow F3, Fig.9). The developer may continue to move in the opposite direction until such time as the pressure near the outlet 50a will not be basically the same as that existing in the hollow portion 57 of the screw 53. This process allows to reduce the high pressure near the outlet 50a of the developer cartridge 50. As a result, when the pressure of the developer near the outlet 50a exceeds a certain pressure level during movement of the developer to the outlet 50a, made of the developer cartridge 50, the transport element 53 of the discharge of the developer in accordance with this embodiment of the invention, can reduce the pressure of the developer.

The transport element 53 of the discharge of the developer (figure 10 and 12) may also be part 53a of small diameter corresponding to the bottom surface of the first portion 51a of the receiving compartment 51 for developer, part 53b large diameter corresponding to the bottom surface is the second part 51b of the receiving compartment 51 of the developer, and the drive shaft 53c. The difference between the diameter D2 of the portion 53b of large diameter and the diameter D1 of the portion 53a of the small diameter of the conveyor element 53 of the discharge of the developer can be the difference in height between the bottom surface of the first part 51a and the bottom surface of the second part 51b, that is, the height of the step S1 of the element 54 of the receiving compartment 51 of the developer. Drive shaft 53c can get energy from the transmitting energy element (not shown)located in the mounting socket 30 developing cartridge 10.

In addition, part 53b large diameter conveyor element 53 of the discharge of the developer can be made so that each blade 56 of the screw will have an increasing width toward the part 53A of small diameter. In this part 53b of the larger diameter of the conveyor element 53 of the discharge of the developer can be performed so that the width S2 of the blade 55 part 53b of the larger diameter part 53a of small diameter, namely the blade 55 part 53b of the large diameter of the stepped element 54 of the receiving compartment 51 for developer, has a size greater than the value of the height S1 of the stepped element 54 of the receiving compartment 51 of the developer. When the width of the blade 55 part 53b of larger diameter in a stepped element 54, more above, the transport element 53 of the discharge of the developer can be effective is actively convey the developer from the receiving compartment 51 of the developer, located at a lower altitude, to the outlet 50a located at a higher elevation.

As a variant part 53b of larger diameter can be made so that only one blade 55 in part 53A of smaller diameter, has a greater width than the blades 56 in other parts. The width S2 of the blade 55 part 53b of larger diameter, which is part 53a of smaller diameter may be greater than the value of the height S1 of the stepped element 54 of the receiving compartment 51 of the developer. In accordance with the embodiment, the portion 53b of the larger diameter of the conveyor element 53 of the discharge of the developer can be made so that the widest part of the blade 55 will be located approximately at the half.

In the above embodiment of the invention, the transport element discharging of the developer described using a hollow screw shape, but it should not be considered limiting. The transport element 53 of the discharge of the developer may have a different design, to the extent that allow the developer to flow in the reverse direction from the outlet 50a. Thus, the transport element 53 of the discharge of the developer may in shape to be similar to the conveyor element 21 or 22 of the supply of the developer described above.

The receiving compartment 51 for p is alawites, for example, shown in figure 10, can be performed so that the width W1 of the first portion 51a which the outlet 50a, may be less than the width W2 of the second portion 51b of the receiving compartment 51. Thus, the width W1 of the first portion 51a may have a size corresponding to the diameter portion 53a of the small diameter of the conveyor element 53 of the discharge of the developer.

Fig diagram of the method of supplying the developer in the developing device 1 suitable for use with the device forming images in accordance with the embodiment of the present invention. Further variants of modes of supply of the developer using the processing device 1 will be described with reference to Fig and 14.

When the pressure of the developer near the outlet 50a of the developer cartridge 50 reaches a pressure unloading P1 and the pressure of the developer near the front opening 20a developing cartridge 10 reaches the value of the supply pressure P2 inside the developing device 1 in accordance with the changes in the values of P1 and P2 can be feed modes, stop and reverse current developer. Mode of submission is when the representative from of the developer cartridge 50 moves in showing the cartridge 10 through the connecting element 40 (arrows F1 and F2). The reverse current is when the developer of the developing cartridge 10 moves in a of the developer cartridge 50 through the connecting element 40 (arrows F3 and F4). Stop mode is when the developer does not move through the connecting element 40.

The developer in the storage compartment 20 developer developing cartridge 10 moves in the direction of the arrow F5 and served on showing the roller 13, for example, two conveying elements 21 and 22 feed the developer, where it is spent. When the developer of the developing cartridge 10 is consumed, the supply pressure P2 can drop to values smaller pressure unloading P1. This ratio determines the feed mode in which the developer from the cartridge 50 moves to showing the cartridge in the direction of the arrow F2 (step S10).

When the developer out of the developer cartridge 50 is adjudged to be in showing the cartridge 10 through the connecting member 40, the pressure in showing the cartridge 10 may increase so that the supply pressure P2 is in General equal to the pressure unloading P1. When the supply pressure P2 becomes the same as the pressure unloading P1, occurs stop mode, that is, the developer from the cartridge to the developer 50 is not moved in showing the cartridge 10 through the connecting element 40 (step S20).

When the supply pressure P2 becomes higher than the pressure of the discharging P, occurs the reverse current, i.e., the developer of the developing cartridge can be moved in a of the developer cartridge 50 through the connecting element 40 in the direction of the arrow F4 (step S30). When the developer of the developing cartridge 10 is consumed, the supply pressure P2 is gradually reduced, resulting in it in General can be compared with pressure unloading P1 of the developer cartridge 50, there again occurs stop mode (step S40). The supply pressure P2 in the end becomes less pressure unloading P1. Therefore, the developer located in the connecting element 40 again moves in showing the cartridge 10. Thus, during the process of printing processing device 1 can operate recurring cycles: feed mode -> stop mode -> mode reverse current -> stop mode -> mode of delivery and so on, thereby constantly maintaining the required amount of the developer in the storage compartment 20 developer developing cartridge 10.

On the other hand, since the transport element 53 of the discharge of the developer cartridge to the developer 50 is a hollow screw form, in the reverse current when the developer of the developing cartridge 10 again flows into the of the developer cartridge 50 through the connecting member 40, the developer entering into of the developer cartridge 50 moves through the second portion 57 of the conveyor element 53 of the discharge of the developer in the direction from the outlet 50a. As a result, the pressure unloading P1 near the outlet 50a may be reduced.

Below the operation of the processing device 1 of the above construction is explained with reference to figure 2, 10 and 15.

When a of the developer cartridge 50 is mounted in the mounting slot 30 developing cartridge 10, the outlet 50a of the developer cartridge 50 may be placed over the connecting element 40. When showing the cartridge 10 of the developer cartridge 50 is installed in the device imaging 100, the developer from the cartridge to the developer is fed in showing the cartridge 10 through the outlet 50a. That is, when showing the cartridge 10, having a of the developer cartridge is installed in the mounting groove, made in the forming device of the image 100, the transport element 53 of the discharge of the developer cartridge to the developer 50 receives energy from the device imaging 100 and can rotate. When the transport element 53 of the discharge of the developer is rotated, the developer located in the receiving compartment 51 of the developer cartridge to the developer 50 is moved to the outlet 50a and is held in the connecting element 40.

The developer received in the connecting member 40, fills the storage compartment 20 of the developer cartridge to the developer tank 10 through the inlet resp is rtie 20a. The developer received in the storage compartment 20 of the developer is moved by, for example, two conveying elements 21 and 22 supply the developer is fed to the roller 14 of the supply of the developer, transferring the developer on showing the platen 13. Developer trapped on the surface showing the roller 13 moves toward the carrier 12 images and converts the electrostatic latent image formed on the media images 12 in the developed image.

When the developer moves toward the carrier 12 images and consumed them, the supply pressure P2 in the input hole 20a of the cartridge to the developer begins to decrease. When the supply pressure P2 developing cartridge is reduced, the developer from the cartridge to the developer 50 is served in manifesting the cartridge 10. After the developer is supplied from the cartridge to the developer 50, so that the supply pressure P2 of the developer cartridge 10 begins to increase, the developer from the cartridge to the developer 50 ceases to be filed, or the developer of the developing cartridge 10 flows back into the cartridge of the developer 50. Therefore, in the storage compartment 20 developer developing cartridge 10, the developer is constantly. The status of movement of the developer in accordance with changes in the feed pressure P2 and the pressure unloading P1 described above, so a detailed description here is not powerjets is.

Fig is a schematic cross-section of the device 100 of forming images using the processing device 1 according to the embodiment of the present invention.

The device 100 imaging (Fig) in accordance with the embodiment of the present invention may have a body 110, device 120 feed print media device 130 document processing device 1, the roller 140 of the image transfer, the recording device 150 and outlet roller 160.

The housing 110 creates the appearance of a device 100 imaging and may contain device 120 feed print media device 130 document processing device 1, the roller 140 of the image transfer, the recording device 150 and outlet roller 160.

The device 120 of the filing of the printing medium is a printing medium P, which has consistently served in the processing device 1. To this end, in the front of the device 12 feed the print media can be installed breathtaking roller 121.

The device 130, the scanner emits a laser beam corresponding to the print data and forms an electrostatic latent image on the carrier 12 of the image processing device 1.

Processing device 1 contains a certain amount of the developer, reveals hidden electrostatics the e image, formed on the carrier 12 images, in the developed image. In the housing 110 processing device 1 is mounted a removable manner. When the developing device 1 is installed in the housing 110, the energy transferred from the drive device (not shown), enters the housing 110, allowing the carrier 12 images, showing the platen 13, the conveying elements 21 and 22 supply of the developer and/or the transport element 53 of the discharge of the developer roll. The construction and operation of the processing device 1 described above, and therefore detailed description is not repeated here.

The roller 140 of the image transfer causes the transfer of the developed image formed on the media image 12 on the printing medium P.

The locking device 150 records on the print medium P developed image transferred on it. Pin cushion displays the print medium P with fixed displayed by the image output device 100 imaging.

Accordingly, when the device 100 imaging receives a signal for printing, it actuates the device 130 of the exposure, the latter emits a laser beam corresponding to the print data and forms a latent electrostatic image corresponding to the specified print data on a medium 12 images item is owocnego device 1. Showing the roller 13 of the developing device 1 supplies the developer to the carrier 12 images, thereby manifesting the latent electrostatic image in the manifest. In the developing device 1 according to the embodiment of the present invention in the storage compartment 20 of the developer showing the developer cartridge 10 is constant.

The device 100 imaging also manages the device 120 feed printed media, which moves the printing medium P between the roller 140 of the image transfer and the carrier 12 images, thanks to which the developed image is transferred from the carrier 12 images 12 on the printing medium P.

Print media P with manifest image passes through the fixing device 150 and outlet roller 160 and brought outside of the device 100 imaging.

In the above-described embodiment of the present invention, in the developing device 1, which can be used with the device imaging, in the case of consumption of developer requires replacement with a new one only of the developer cartridge 50.

In the developing device 1, which can be used with the device imaging, in the above-described embodiment of the present invention, when the supply of the developer from the cartridge to the developer 50 in PR is showing the cartridge 10, when the pressure in showing the cartridge 10 and the connecting element 40 increases compared to the set value, while the transport element 53 of the discharge of the developer continues to rotate for feeding the developer, the developer does not move in showing the cartridge 10 and/or it may flow back from the developing cartridge 10 a of the developer cartridge 50, therefore showing the cartridge 10 is always a certain amount of the developer.
