Description
Technical Field
The present invention relates to a process cartridge, and more particularly, to a force receiving assembly of a process cartridge detachably mounted in an image forming apparatus.
Background
An electronic imaging device is a device that forms an image on a recording medium. Some examples of the electrophotographic apparatus are electrophotographic copiers, electrophotographic printers (laser printers, LED printers, etc.), and the like. The recording medium is a medium on which an image is formed by using an electrophotographic image forming process. Some examples of the recording medium are recording paper, OHP sheet, label, and the like. The process cartridge is a cartridge in which an electrophotographic photosensitive member and a means for processing the electrophotographic photosensitive member are disposed together, and which is removably mountable in a main assembly of an electrophotographic image forming apparatus.
The process cartridge is a cartridge including a developing unit including a photosensitive drum and a photosensitive unit including a developing roller that can develop an electrostatic latent image formed on the photosensitive drum.
During the image forming operation, the developing roller remains pressed toward the photosensitive drum. In the case where the electrophotographic apparatus employs a developing method in which a developing roller is placed in contact with a photosensitive drum to develop a latent image on the photosensitive drum, the developing roller remains pressed against the outer peripheral surface of the photosensitive drum.
If the developing roller is kept in contact with the photosensitive drum when an image is not formed, the developer on the developing roller may adhere to the photosensitive drum to form unnecessary development. In addition, the contact of the photosensitive drum and the developing roller is maintained during both image formation and image non-formation of the electrophotographic apparatus, and the photosensitive drum, the developing roller, and the developer may be prematurely degraded due to friction between the photosensitive drum and the developing roller. In addition, in the case where the process cartridge is not mounted to the electronic image forming apparatus, it is also necessary to separate the developing roller from the photosensitive drum to prevent the developing roller and the photosensitive drum from being contaminated with each other by long-term contact.
In the prior art, in order to enable the process cartridge to be mounted in the electronic imaging device before the developing roller and the photosensitive drum are switched between the contact position and the separation position, a force application part for individually pushing the developing unit relative to the photosensitive unit is arranged in the electronic imaging device, a separation force receiving part matched with the force application part in the electronic imaging device is required to be arranged on the developing unit, which complicates the structures of the electronic imaging device and the process cartridge, and in the electronic imaging device with a plurality of process cartridges, the process cartridge provided with the separation force receiving part also causes the problem of inconvenient mounting when being mounted in the electronic imaging device, and an interference preventing structure between the separation force receiving part and the force application part is required to be additionally prevented in the process of mounting the process cartridge, so that the structure becomes more complicated.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the following description, the extending direction of the rotation axis of the photosensitive drum is referred to as the longitudinal direction of the process cartridge, and for the purpose of description, the longitudinal direction is also referred to as the first direction in the following description.
Examples
As shown in fig. 1 and 2, the process cartridge of the present invention includes a photosensitive unit 1 and a developing unit 2, the photosensitive unit 1 and the developing unit 2 being connected by a shaft so that the developing unit 2 can rotate relative to the photosensitive unit 1. The photosensitive unit 1 includes a photosensitive drum 6, a first power receiving member 4, and a handle 3; the developing unit 2 includes a developing roller 7 and a second power receiving member 5. The first power receiving part 4 is provided at one side of the longitudinal direction of the process cartridge, which receives the driving force of the first driving shaft in the electronic image forming apparatus to drive the photosensitive drum 6 to rotate, and the second power receiving part 5 is provided at the same side of the longitudinal direction of the process cartridge as the first power receiving part 4, which receives the driving force of the second driving shaft in the electronic image forming apparatus to rotate to drive the developing roller. The electronic imaging device is provided with a tray which can be pulled out and pushed in, and the processing box is arranged in the tray and then is arranged in the electronic imaging device along with the tray. An elastic coupling member (not shown) is provided between the developing unit 2 and the photosensitive unit 1, and the elastic coupling member can urge the developing roller 7 to contact the photosensitive drum 6.
As shown in fig. 3 to 5, the driving end of the process cartridge in this embodiment includes an axially movable member 8, an elastic member 9, a driving part 10, a gear cover 11, and a side cover 12. The elastic member 9 is installed between the axial moving element 8 and the driving part 10, and the driving part 10 and the second power receiving part 5 are the same part, but the driving part 10 can be provided separately from the second power receiving part 5 as a driving part for driving the axial moving element 8 to move. The driving part 10 is provided with a driving part 10a and a receiving part 10b, the axially movable member 8 is provided with a driven part 8a and a rotation limiting part 8b, the developing unit is provided with an abutting part 201, the driven part 8a can be matched with the driving part 10a, when the driving part 10 rotates, the driving part 10a is matched with the driven part 8a, the rotation limiting part 8b is limited to rotate by the abutting part 201, and the axially movable member 8 moves towards the driving part 10 against the elastic force of the elastic member 9. When the rotation restricting portion 8b moves closer to the driving member 10 by a certain stroke, the rotation restricting portion 8b is disengaged from the abutting portion and then rotates together with the driving member 10.
As shown in fig. 3 to 7, one end 13a of the flexible member 13 is fixed to the first fixed end 2a of the developing unit 2, passing through the intermediate turning portion 1a of the photosensitive unit in the middle, and the other end 13e is fixed to the second fixed end 2b of the developing unit of the photosensitive unit. In order to make the flexible member flexible and rigid, the flexible member is preferably an elastic steel wire, but is not limited thereto, and other flexible materials may be used. The portion of the flexible member 13 between the intermediate turns 1a of the first fixed end 2a is referred to as a first portion 13b, the portion between the intermediate turns 1a and the second fixed end 2b is referred to as a second portion 13d, and the portion contacting the intermediate turns 1a is referred to as a turning point 13c. The first portion 13b of the flexible member 13 is configured to cooperate with the outer flange 8c of the axially movable member 8, specifically, the flexible member 13 surrounds the inner side of the outer flange 8c, when the axially movable member 8 moves in the first direction close to the abutment 201, the outer flange 8c makes the flexible member deformable in the first direction by pushing the first portion 13b of the flexible member 13, and when the first portion 13b deforms in the first direction, the actual length between the one end 13a of the flexible member 13 and the intermediate turning point 1a will become longer, and the flexible member 13 will move by pulling the intermediate turning point 1a through the turning point 13c, so that the photosensitive unit 1 rotates against the above-mentioned elastic force pushing the developing roller 7 against the elastic connection of the photosensitive drum 5, eventually separating the photosensitive drum 6 from the developing roller 7. The flexible component 13 may also be directly fixed at one end 13a on the first fixing portion 2a of the developing unit 2, and the other end is fixed on the middle turning portion 1a of the photosensitive unit 1, and by using the deformation of the flexible component 13, the technical effect that the developing unit rotates relative to the photosensitive unit to separate the developing roller from the photosensitive drum can also be achieved.
When the process cartridge is not mounted to the electronic image forming apparatus, the elastic force of the elastic member 9 urges the axially movable member 8 to move away from the driving part 10 in the first direction with respect to the driving part 10. At this time, the axially movable member 8 is forced to push the first portion 13b of the flexible member 13 to deform, and the flexible member 13 moves by pulling the intermediate turning point 1a through the turning point 13c, so that the developing unit 2 rotates relative to the photosensitive unit 1 to separate the developing roller 7 from the photosensitive drum 6.
When the electronic image forming apparatus starts driving the process cartridge into the image forming operation, the driving member 10 starts rotating, the driving portion 10a of the driving member 10 has a tendency to drive the axially movable member 8 to rotate through the driven portion 8a, but since the rotation restricting portion 8b of the axially movable member 8 is restricted from rotating by abutting against the abutting portion 201 at this time, the driving portion 10a will pull the driven portion 8a to move in the first direction toward the driving member 10 against the elastic force of the elastic member 9, the driven portion 8a will enter into the accommodating portion 10b, and during the movement of the axially movable member 8 toward the driving member 10, the first portion 13b of the flexible member 13 will also resume deformation, causing the developing roller 7 to contact the photosensitive drum 6 through the elastic connection provided between the developing unit 2 and the photosensitive unit 1, thereby realizing the image forming operation. When the axially movable element 8 moves away from the abutment 201, the final rotation limiter 8b is out of contact with the abutment 201, and the axially movable element 8 rotates together with the driving member 10. When the axially movable member 8 rotates together with the driving member 10 (the second power receiving member 5), the deformation of the first portion 13b of the flexible member 13 is recovered, and the developing unit rotates relative to the photosensitive unit under the elastic force of the elastic coupling member provided between the developing unit and the photosensitive unit so that the developing roller contacts the photosensitive drum, and the process cartridge can normally perform an image forming operation.
After the image forming operation is completed, the elastic force of the elastic member 9 will force the axially movable member 8 to push and move toward the principle driving member 10 along with the stop rotation of the driving member 10, the axially movable member 8 forces the first portion 13b of the flexible member 13 to deform, and the flexible member 13 forces the photosensitive unit to rotate relative to the developing unit so that the photosensitive drum and the developing roller move from the contact position to the separation position.
Summarizing the above, it is only necessary to provide in the process cartridge a partitioning mechanism that is linked with the second power receiving member 5, such that when the second power receiving member 5 stops rotating, the partitioning mechanism can force the developing unit 2 to rotate relative to the photosensitive unit 1 so that the developing roller 7 is spaced from the photosensitive drum 6, and when the second power receiving member 5 does not rotate, the partitioning mechanism allows an elastic connector provided between the developing unit 2 and the photosensitive unit 1 to force the developing unit 2 to rotate relative to the photosensitive unit 1 so that the developing roller 7 is in contact with the photosensitive drum 6. Preferably, the partitioning mechanism in this embodiment includes an axially movable member 8, an elastic member 9, a driving part 10, and a flexible part 13, with which the developing roller and the photosensitive drum are moved before the partitioning position and the contact position, between a deformed state and a recovery deformed state. Alternatively, the partition mechanism may employ other mechanisms that are coupled to the second power receiving element.

When the space holding projection 15a is disengaged from the space holding hole 1201a, the developing unit rotates relative to the photosensitive unit by the elastic force of the elastic coupling provided between the developing unit and the photosensitive unit so that the developing roller 7 contacts the photosensitive drum 6.

The second elastic member 14 is provided between the housing 1 and the space holding part 15, with one end abutting the housing 1 and the other end abutting the space holding part 15.
