Description

Technical Field

[0001] The present application relates to the field of image forming technology, and in particular to a processing box. Background Art

[0002] In the prior art, an electronic imaging device generally includes a driving unit for outputting a rotational driving force, and a processing box can be detachably mounted on the electronic imaging device and cooperate with the driving unit to receive the rotational driving force output by the driving unit. Generally, the processing box includes a power receiving unit, a developing unit, a developer, a powder control unit, and a shell for accommodating the above-mentioned units. The power receiving unit is arranged at one end of the processing box along the axial direction of the developing unit, and according to different types of processing box structures, some processing boxes may also include a photosensitive unit, a charging unit, a cleaning unit, and a stirring unit, etc. When the processing box is installed on the electronic imaging device, the power receiving unit and the driving unit of the electronic imaging device are engaged with each other, thereby transmitting the rotational driving force output by the driving unit to the processing box to drive the rotating units (such as the developing unit, the photosensitive unit, the stirring unit, etc.) inside the processing box to rotate, thereby participating in the development work of the electronic imaging device.

[0003] However, in the prior art, the initial state of the driving unit is in an inclined state, that is, the driving unit and the power receiving unit are not coaxial. During the contact and engagement process between the power receiving unit and the driving unit, structural interference will occur between the two, making it difficult or impossible for the power receiving unit and the driving unit to accurately engage with each other and transmit the driving force, so that it takes a certain amount of time for the power receiving unit and the driving unit to engage, affecting the working efficiency of the processing box. Summary of the Invention

[0004] In order to overcome the problems existing in the above-mentioned prior art, the main purpose of this application is to provide a processing box that can improve work efficiency.

[0005] In order to achieve the above objectives, this application specifically adopts the following technical solutions:

[0006] The present application provides a process cartridge comprising:

[0007] Box body;

[0008] a developing roller rotatably disposed on the box body;

[0009] a photosensitive drum rotatably disposed on the box body;

[0010] When the processing box is installed on the electronic imaging device, the developing roller is engaged with the gear portion of the driving unit of the electronic imaging device via the first gear, wherein in the axial direction of the developing roller, at least a portion of the first gear protrudes from the end of the photosensitive drum.

[0011] Compared with the existing technology, the present application can make the contact and engagement process between the photosensitive drum or developing roller of the processing box and the driving unit of the electronic imaging device smoother, greatly saving the time for the contact and engagement between the photosensitive drum or developing roller and the driving unit, and improving the working efficiency of the processing box.

[0292] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0293] In the description of this application, unless otherwise specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0294] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described from the perspectives shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also indirectly connected to the other element "on" or "under" through an intermediate element.

[0295] Figure 1 、 Figure 2 FIG. 1 is a schematic diagram of the structure of a drive unit in the prior art where the process cartridge is not installed in an electronic imaging device. Figure 1 、 Figure 2 As shown, an electronic imaging device (not shown) is provided with a drive unit 1080, wherein the drive unit 1080 has a power transmission member 1080e for transmitting a rotational driving force to the process cartridge. Specifically, the drive unit 1080 is supported by a support portion 1085a of a support member 1085. Further, a first contacted portion 1080h abuts against a first contact protrusion 1004 provided in the electronic imaging device. Simultaneously, the pressing component 1003 applies a pushing force FF2 to the pressed portion 1080i of the drive unit 1080 via a spring 1006, causing a second contacted portion 1080j to contact the second contact protrusion 1005. At this time, the drive unit 1080 is in an initial position. When viewed along a direction parallel to the axis of the support member 1085, i.e., the direction of arrow HH, the axis direction EE of the drive unit 1080 is inclined relative to the center RR of the support portion 1085a.

[0296] When the processing box is installed in the electronic imaging device, the power receiving unit of the processing box will come into contact with the driving unit 1080, so that the driving unit 1080 is transformed from the inclined state in the initial position to be parallel to the axial direction of the support member 1085, so as to successfully match and engage with the power receiving unit and thus transmit the driving force.

[0297] However, structural interference will occur between the power receiving unit and the driving unit 1080 during their contact and engagement process, making it difficult or impossible for the power receiving unit and the driving unit 1080 to accurately engage with each other and transmit power. In this way, it takes a certain amount of time for the power receiving unit and the driving unit 1080 to engage, and the working efficiency of the processing box will also be affected.

[0298] Example 1

[0299] An embodiment of the present application provides an electronic imaging device, which includes a processing box 1, a driving unit 1080 and a driving unit protective cover 1081, wherein the driving unit protective cover 1081 is disposed outside the driving unit 1080.

[0300] The electronic imaging device may be a printer, a copier, a scanner-copier, etc., without limitation. The following description of the solution takes a printer as an example. The process cartridge may be a toner cartridge, an ink cartridge, etc.

[0301] The processing box generally consists of a powder hopper unit and a waste powder hopper unit. The powder hopper unit includes a developing roller, a powder knife, a powder feed roller and a stirring frame, while the waste powder hopper unit includes a photosensitive drum, a charging roller and a cleaning scraper. The processing box also usually contains a developer and a power receiving unit that receives an external driving force. The power receiving unit includes a drive head and a drive gear arranged at one end of the photosensitive drum. Furthermore, the processing box is also provided with a positioning component that cooperates with the machine. The developing roller rotates under the action of the drive to drive the developer to be transferred to the photosensitive drum. The powder knife can adjust the uniformity of the developer on the developing roller. The stirring frame can loosen the developer in the powder hopper unit. The charging roller charges the photosensitive drum, and the cleaning scraper cleans the excess developer on the photosensitive drum after development.

[0302] Figure 3 Schematic diagram of the structure of the processing box in this application. Figure 3 As shown, the process cartridge 1 includes a cartridge body A10, a photosensitive drum 20, a developing roller 30, and a power receiving unit 21. The cartridge body A10 contains a developer, and the photosensitive drum 20 and the developing roller 30 are rotatably mounted on the cartridge body A10. The power receiving unit 21 is disposed at one end of the cartridge body A10 and connected to the photosensitive drum 20. The power receiving unit 21 is configured to engage with a drive unit of an electronic imaging device to receive a driving force outputted by the drive unit of the electronic imaging device.

[0303] Specifically, the housing A10 includes a bracket A11, which may be a photosensitive drum frame. The bracket A11 includes a first fixing post A111 and a through hole A112. The power receiving unit 21 is fixed to the bracket A11 through the through hole A112 and is exposed outside the through hole A112 to receive the driving force output by the driving unit 1080. The first fixing post A111 is disposed above and / or in front of the power receiving unit 21 relative to the axial direction of the photosensitive drum 20.

[0304] In order to transform the drive unit 1080 from the inclined state of the initial position to a horizontal state capable of engaging with the power receiving unit 21, the processing box 1 also includes a pressing member A40, which is fixedly arranged on the box body A10 and is located at the same end of the box body as the power receiving unit 21. It is used to press the drive unit 1080 during the installation process of the processing box 1 so that the drive unit 1080 is adjusted to the correct position.

[0305] Furthermore, the pressing member A40 is removably mounted on the first fixing post A111, thereby securing it to the bracket A11. At least a portion of the pressing member A40 is positioned outside the power receiving unit 21 in the axial direction of the photosensitive drum 20. Optionally, the pressing member A40 is configured as a roller, the outer surface of which serves as a guiding pressing surface, capable of guiding and pressing the drive unit to position it correctly. Furthermore, the outer surface of the roller may be coated with a rubber coating to prevent structural interference between the pressing member A40 and the drive unit 1080, which could result in wear of the drive unit.

[0306] Figures 4 to 6 Schematic diagram of the process of contact and engagement between the power receiving unit of the processing box and the driving unit of the electronic imaging device in this application. Figure 4As shown, when the processing box 1 is installed in the electronic imaging device along the Y1 direction, the pressing member A40 fixed on the bracket also gradually approaches the driving unit 1080 as the processing box moves. When the pressing member A40 contacts the driving unit 1080 to form structural interference, the pressing member A40 applies a pressing force F to the driving unit 1080. After receiving the pressure, the driving unit 1080 moves in the direction close to the power receiving unit 21, so that the driving unit 1080 contacts the pressing member A40 and drives the pressing member A40 to rotate. At the same time, since the pressing member A40 is fixedly installed on the bracket, during the process of engagement between the power receiving unit 21 and the driving unit 1080, the pressing member A40 always remains parallel to the axial direction of the photosensitive drum 20, that is, the distance between the pressing member A40 and the axis of the photosensitive drum 20 does not change. As the processing box 1 is installed in place, the drive unit 1080 moves from the initial position to a position parallel to the axial direction of the support member A1085. At this time, the pressing member A40 is set above and / or in front of the power receiving unit 21 relative to the axial direction of the photosensitive drum 20. Finally, the drive unit 1080 is successfully engaged with the power receiving unit 21, so that the drive unit 1080 transmits the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate.

[0307] In this embodiment, a pressing member is provided on the processing box, and the pressing member A40 forces the driving unit 1080 to move from an initial inclined position to a position roughly parallel to the axial direction of the photosensitive drum, and in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member and the projection of the photosensitive drum do not overlap at all, thereby making the process of contact and engagement between the power receiving unit and the driving unit smoother, greatly saving the time for contact and engagement between the power receiving part and the driving unit, and improving the working efficiency of the processing box.

[0308] Example 2

[0309] In this embodiment, another processing box is provided, and the unspecified parts are the same as the processing box structure in the first embodiment.

[0310] like Figure 7 and Figure 8 As shown, the processing box 1 further includes a movable positioning member B50, which is movably arranged on the bracket B11 and is located at the same end as the power receiving unit 21, and the positioning member B50 can be displaced relative to the bracket B11 in a first direction, wherein the first direction is the height extension direction of the processing box ( Figure 8 Furthermore, bracket B11 defines a slide groove B15. Slide groove B15 may be rectangular, circular, or have other regular or irregular structures, without limitation. Positioning member B50 is slidably disposed within slide groove B15, allowing positioning member B50 to move relative to the box body along slide groove B15.

[0311] When the processing box 1 is installed into the interior of the electronic imaging device through the mounting guide rail B900 on the inner side of the electronic imaging device along the forward direction (installation direction of the processing box), the positioning member B50 is supported by the mounting guide rail B900 on the inner side of the electronic imaging device and moves forward along the mounting guide rail B900. Because the positioning member B50 is movable relative to the cartridge body and is supported on the mounting guide rail B900 during installation, the cartridge body of the process cartridge 1 can be displaced relative to the mounting guide rail B900 of the electronic imaging device during installation. The pressing member B40 located at the end of the cartridge body also moves a certain amount (at least vertically) relative to the drive unit 1080 within the electronic imaging device or the mounting guide rail B900 of the electronic imaging device as the process cartridge 1 moves as a whole. This movement allows the pressing member B40 to achieve a certain upward displacement relative to the drive unit 1080. Once the process cartridge is installed, the pressing member B40 can move downward, pressing the drive unit 1080, causing the drive unit 1080 to engage substantially coaxially with the power receiving unit 900 to transmit the driving force. Furthermore, the pressing member B40 forces the drive unit 1080 from its initial tilted position to a position substantially parallel to the axial direction of the photosensitive drum, and in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member and the projection of the photosensitive drum do not overlap at all.

[0312] In this embodiment, due to the setting of the positioning member B50, the pressing member B40 is installed in the electronic imaging device when the processing box 1 is installed. The positioning member B50 can move relative to the box body along the slide groove B15, and drive the pressing member B40 set on the box body to move relative to the box body, that is, the pressing member B40 can obtain a certain amount of movement, so that the pressing member B40 installed on the processing box 1 can more easily press down the driving unit 1080 to avoid mutual interference.

[0313] In addition, the technical solutions of the above-mentioned embodiment 1 and embodiment 2 can also be used in combination with each other, such as applying the movable positioning part of embodiment 2 to the processing box of embodiment 1 to increase the function and make it easier for the processing box of embodiment 1 to achieve engagement between the power receiving unit and the driving unit. The embodiments are not mutually exclusive.

[0314] Example 3

[0315] This embodiment provides another pressing member, which is a further improvement on the basis of the second embodiment. The unexplained parts are the same as those in the aforementioned embodiments and will not be described again for the sake of simplicity.

[0316] like Figure 9 and Figure 10As shown, the process cartridge 1 further includes a movable positioning member C50 and an elastically retractable member C60. The positioning member C50 is disposed on a bracket C11 and is located at the same end of the cartridge body as the power receiving unit 21. The positioning member C50 is connected to the bracket C11 via an elastically retractable member F60, thereby enabling the positioning member C50 to move relative to the process cartridge body. The process cartridge 1 further includes a pressing member C40, which is connected to the bracket C11 via a connecting rod C70. Specifically, the pressing member C40 is a gear, and the outer surface of the gear serves as a guide pressing surface.

[0317] When the process cartridge 1 is installed into the electronic imaging device along the mounting guide rails C900 on the inner side of the electronic imaging device in the forward direction (the direction in which the process cartridge is installed), the positioning member C50 is supported by the mounting guide rails C900 on the inner side of the electronic imaging device and moves forward along the mounting guide rails C900. Because the positioning member C50 is movable relative to the process cartridge 1 and is supported on the mounting guide rails C900 during the installation process, the process cartridge 1 can move a certain amount relative to the mounting guide rails C900 of the electronic imaging device during the installation process.

[0318] Specifically, in the process of installing the processing box 1 into the electronic imaging device, the pressing member C40 will first touch the retaining wall 1081 provided on the periphery of the driving unit 1080, thereby causing the entire processing box to move upward relative to the mounting guide rail C900 to avoid the high point in the assembly process. When the processing box is completely installed in place, the processing box also moves downward to the specified position. In the process of the processing box moving downward, the pressing member C40 provided in front of it also moves a certain amount of movement relative to the driving unit 1080 inside the electronic imaging device or the mounting guide rail C900 of the electronic imaging device as the processing box moves as a whole (at least it can move up and down).

[0319] like Figure 11 and Figure 12As shown, when the pressing member C40 fixed on the bracket C11 gradually approaches the driving unit 1080 and contacts the driving unit 1080 as the processing box moves, the gear portion C40a of the pressing member C40 forms structural interference and meshes with the gear portion C1081b of the driving unit 1080. Since the gear module of the pressing member C40 is slightly different from the gear module of the driving unit 1080, after the two are meshed for several tooth shapes, the pressing member C40 and the driving unit 1080 will have a top tooth. At the same time, because the pressing member C40 is fixed relative to the processing box, when top tooth occurs, the driving unit 1080 can move from the initial inclined position to a position approximately parallel or coaxial with the axial direction of the power receiving unit 21 through the engagement with the pressing member C40, and in the plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member and the projection of the photosensitive drum do not overlap at all, and finally the driving unit 1080 and the power receiving unit 21 are successfully meshed. During the entire process, the distance between the pressing member C40 and the axis of the photosensitive drum does not change.

[0320] In some embodiments, after the driving unit 1080 rotates, the driving unit 1080 can be smoothly engaged with the power receiving unit 21 .

[0321] Example 4

[0322] like Figure 13 As shown, a block-shaped protrusion D1010 is provided on the side wall of the electronic imaging device. The block-shaped protrusion D1010 is located above the drive unit 1080 or the mounting rail 900 (part) and is located in the installation space of the processing box 1 in the electronic imaging device (refer to Figure 31 For the remaining unexplained parts, reference may be made to the contents of the aforementioned embodiments, which will not be described again for simplicity.

[0323] like Figures 13 to 16b As shown, this embodiment provides another pressing member in the processing cartridge. In this embodiment, the pressing member D40 is fixedly mounted on the processing cartridge 1 or is integrally formed with the processing cartridge and is located on the same side as the power receiving unit 21. In a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member D40 and the projection of the photosensitive drum do not overlap at all. The pressing member D40 also includes a guiding pressing surface D40a1 (an inclined surface or an arc surface). The guiding pressing surface D40a1 is disposed on the side of the front end of the pressing member D40 (the installation direction of the processing cartridge 1) facing the power receiving unit 21. The guiding pressing surface D40a1 corresponds to the block-shaped protrusion D1010. The installation process of this embodiment is as follows:

[0324] like Figure 13 、 Figure 14aAs shown, when the processing box 1 is installed into the electronic imaging device along the Y1 direction, the front end of the pressing member D40 corresponds to the block protrusion D1010 on the side wall of the electronic imaging device. As the processing box 1 continues to be installed and moved, the guiding pressing surface D40a1 of the pressing member D40 abuts against the block protrusion D1010, and the pressing member D40 moves upward and forward under the action of the guiding pressing surface D40a1 and the block protrusion D1010. Since the pressing member D40 is fixedly provided on the processing box 1 or the pressing member D40 is integrally formed with the processing box, the upward movement of the pressing member D40 will also drive the front end of the processing box 1 to move upward, causing the processing box 1 to rotate counterclockwise as a whole (as viewed from the axial direction of the power receiving unit 21).

[0325] like Figure 14b As shown, as the process cartridge 1 continues to be installed, the pressing member D40 moves upward over the block-shaped protrusion D1010 and then moves to the top of the retaining wall 1081. At this time, the front end of the pressing member D40 is about to pass over the top of the retaining wall 1081 and enter the opening position of the retaining wall 1081 to contact the drive unit 1080, as shown in FIG. Figure 15a shown.

[0326] like Figure 15b As shown, after the process cartridge 1 is installed in place in the electronic imaging device, the pressing member D40 is located above the driving unit 1080. Observed from the back of the process cartridge 1, one end 1A of the process cartridge 1, i.e., the end where the power receiving unit 21 is located, is located higher in the electronic imaging device than the other end 1B of the process cartridge 1 (part of the process cartridge 1 is tilted upward).

[0327] like Figure 16a 、 Figure 16b As shown, as the door cover of the electronic imaging device closes, the pressure rod D1020 on the inside of the door cover presses down on the upper surfaces 1C on the left and right sides of the back of the processing cartridge 1, applying force to the entire processing cartridge 1. The front end of the processing cartridge 1 then moves downward, driving the pressing member D40 downward. At this time, the front end of the pressing member D40 presses down on the drive unit 1080, causing it to move downward until it is substantially coaxial with the power receiving unit 21, thereby receiving the driving force. Because the power receiving unit 21 is coaxial with the drive unit 1080, the lower rear end portion of the processing cartridge 1 rotates clockwise. When the pressure rod D1020 applies pressure to the left and right sides of the processing cartridge 1, the two ends (1A, 1B) of the processing cartridge 1 remain substantially horizontal.

[0328] In some embodiments, the processing box can also press the front end of the pressing member D40 downwardly on the driving unit 1080 under the action of its own gravity, so that the driving unit 1080 moves downwardly and is basically coaxial with the power receiving unit 21 to receive power.

[0329] Example 5

[0330] This embodiment is further improved on the basis of the fourth embodiment, and the unexplained parts are the same as those in the fourth embodiment. Figure 17a-Figure 18 As shown, the process cartridge further includes a position limiting guide E40b, an elastic member (not shown), and a guide control component E40c. The position limiting guide E40b is movably mounted on the end cap of the process cartridge 1 and is located at the same end of the cartridge body as the power receiving unit 21. The position limiting guide E40b is capable of displacement in the axial direction of the photosensitive drum. Specifically, the position limiting guide E40b can be a protrusion disposed on the end cap of the process cartridge 1, for example, a cylindrical structure. The elastic member is sleeved over the position limiting guide E40b, with the ends of the elastic member respectively pressing against the position limiting guide E40b and the inner wall of the end cap. The elastic member applies a force directed toward the interior of the end cap to the position limiting guide E40b. When not subjected to other external forces, the position limiting guide E40b remains retracted on the end cap, preventing interference between the end cap of the process cartridge 1 and the inner wall of the electronic imaging device during installation.

[0331] The guide control component E40c can be a swing rod, which can be set inside the end cover of the processing box 1. The receiving portion of the swing rod is located at the rear position of the processing box, and receives the pressure from the pressure rod E1020 ( Figure 18 The present embodiment is similar to the fourth embodiment in that the pressing member E40 is fixedly mounted on the cartridge body or integrally formed with the process cartridge. When the process cartridge 1 is properly installed in the electronic imaging device, the pressing member E40 is positioned above the drive unit 1080.

[0332] Furthermore, as the electronic imaging device door cover closes, the pressure rod E1020 on the inside of the door cover presses down on the upper surfaces 1C of the left and right sides of the rear back portion of the processing cartridge 1 housing, applying force to the entire processing cartridge 1. The front end of the processing cartridge 1 subsequently moves downward, driving the pressure member E40 downward. The front end of the pressure member E40 then presses down on the drive unit 1080, causing it to move downward until it is substantially coaxial with the power receiving unit 21, thereby receiving power. The pressure member E40 forces the drive unit 1080 from its initial tilted position to a position approximately parallel to the axis of the photosensitive drum. Furthermore, in a plane perpendicular to the axis of the photosensitive drum, the projection of the pressure member E40 and the projection of the photosensitive drum do not overlap at all. Because the power receiving unit 21 is coaxial with the drive unit 1080, the lower rear end portion of the processing cartridge 1 rotates clockwise. With the pressure rod E1020 applying pressure to the left and right sides of the processing cartridge 1, the two ends (1A, 1B) of the processing cartridge 1 remain substantially horizontal. At the same time, the pressure lever E1020 also presses the guide control component E40c, causing it to move in the direction of arrow R within the end cap. This, through the use of beveled surfaces and other means, causes the position-limiting guide E40b, which was originally retracted into the end cap, to extend from the end cap (in the figure, the position-limiting guide E40b extends perpendicular to the paper). At this point, since the process cartridge is in the correct position, the extended position-limiting guide E40b can snap into a position-limiting groove E1011 located in the electronic imaging device, thereby securing the installed process cartridge and preventing it from shaking, allowing for stable printing.

[0333] When the process cartridge needs to be removed from the electronic imaging device, the door cover is opened, and the pressure rod E1020 is lifted. Then, as the force applied to the guide control component E40c disappears, the elastic restoring force of the elastic member connected to the limit guide E40b causes the limit guide E40b to retract into the end cover, and also causes the guide control component E40c to return to its pre-installation state. Preferably, the pressure rod E1020 first presses the upper surface 1C of the process cartridge 1 to adjust the process cartridge to the correct position, and then the pressure rod E1020 applies force to the guide control component E40c, allowing the limit guide E40b to extend and snap into the limit groove E1011. This process can be achieved by providing different step surfaces on the pressure rod E1020 along its travel direction, for example, providing a first step surface E1021 and a second step surface E1022 in sequence along the travel direction (arrow M) of the pressure rod E1020. When the door cover is closed and the pressure rod E1020 is pressed toward the interior of the device, the first stepped surface E1021 first presses against the process cartridge upper surface 1C, causing the process cartridge to align. Then, as the pressure rod E1020 presses further, the second stepped surface E1022 begins to contact the force-bearing surface of the pressure guide control component E40c, thereby allowing the position-limiting guide E40b to extend into the position-limiting groove E1011. Furthermore, the guide control component E40c is not limited to being located within the end cover; it may also be located outside the process cartridge, and this is not a limitation here.

[0334] Example 6

[0335] Based on the second or fourth embodiment, this embodiment provides another processing box structure. Figure 19 and Figure 20 As shown, the processing box 1 includes a power receiving unit 21, a bracket F11, a pressing member F40 and a control mechanism F30. The power receiving unit 21 is movably arranged at one end of the box body for receiving the driving force of the electronic imaging device. The control mechanism F30 is used to control the power receiving unit 21 to produce displacement in the axial direction of the photosensitive drum. The pressing member F40 is fixedly arranged on the box body or the pressing member F40 is integrally formed with the processing box and is located at the same end as the power receiving unit 21. The pressing member F40 can press the driving unit 1080 (such as Figure 15b (as shown), aligning the drive unit. The pressing member F40 forces the drive unit 1080 from its initial tilted position to a position approximately parallel to the photosensitive drum axis. In a plane perpendicular to the photosensitive drum axis, the projection of the pressing member F40 and the projection of the photosensitive drum do not overlap at all. A bracket F11 is provided at one end of the housing and is provided with an elongated groove F110 and multiple mounting holes F113. The groove F110 has a first end F111 and a second end F112.

[0336] like Figure 21As shown, the control mechanism F30 includes a fixing member F31 and a pressing member F32. The fixing member F31 is provided with a plurality of fixing holes F311 and ribs F312. A connecting column F321 is provided at one end of the pressing member F32, and a pressing portion F323 is provided at the other end of the pressing member F32. The pressing portion F323 has an inclined surface, and the middle portion F322 of the pressing member F32 is a chamfered structure, so that there is a height displacement difference between the connecting column F321 and the pressing portion F323 in the width direction of the pressing member F32.

[0337] like Figures 22 to 24 As shown, the processing box 1 also includes a hub F60, a movable part F50, a connecting part F70 and a first elastic part F90. The power receiving unit 21 is provided with an engaging portion F213 and a connecting hole F211 for engaging with the drive unit 1080. An abutment surface F212 extending outward along the axis of the power receiving unit 21 is provided between the engaging portion F213 and the connecting hole F211. The movable part F50 is a cylindrical structure. Specifically, the movable part F50 includes an upper surface F53, a lower surface F54, a through hole F52 and a protrusion F51. The protrusion F51 is provided on the upper surface F53, protruding in a direction away from the upper surface F53 and having an inclined surface. The outer circumference of the hub F60 is provided with a gear portion, and the interior of the hub F60 is also provided with two spaced support portions F61.

[0338] like Figure 25 and Figure 26 As shown, the assembly relationship of the above-mentioned parts is as follows: the movable part F50 is movably arranged in the wheel hub F60, so that the lower surface F54 of the movable part F50 abuts against the support portion F61 of the wheel hub F60; the power receiving unit 21 is installed in the movable part F50 through the through hole F52 of the movable part F50. At this time, the abutting surface F212 ( Figure 22 ) abuts against the upper surface F53 of the movable part F50, so that the power receiving unit 21 is fixedly supported on the movable part F50 and can move relative to the wheel hub F60 together with the movable part F50; the connecting part F70 passes through the connecting hole F211 of the power receiving unit 21, and the two ends of the connecting part F70 are placed in the supporting part F61 built into the wheel hub F60 to drive the wheel hub F60 to rotate after the power receiving unit 21 receives the driving force from the driving unit 1080; the first elastic part F90 is arranged in the wheel hub F60, and one end of the first elastic part F90 abuts against the bottom surface of the wheel hub F60, and the other end of the first elastic part F90 abuts against the two ends of the connecting part F70.

[0339] The aforementioned components cooperate with each other and can be integrally assembled to one end of the photosensitive drum 20. Upon receiving a driving force, the hub F60 can drive the photosensitive drum 20 to rotate and transmit the driving force to the developing roller gear 31 via the gear portion of the hub F60, thereby driving the developing roller 30 to rotate. The bracket F11 covers the movable member F50, and the protrusions F51 on the power receiving unit 21 and the movable member F50 are exposed externally through the bracket F11. The pressing member F32 is movably connected to the bracket F11 via a second elastic member F80. Specifically, the pressing member F32 and the second elastic member F80 are respectively mounted in a groove F110 of the bracket F11, with one end of the second elastic member F80 connected to the first end F111 of the groove F110 and the other end of the second elastic member F80 connected to the connecting post F321 of the pressing member F32. Optionally, the second elastic member F80 can be a spring or a compression spring. In order to fix the pressing member F32 on the bracket F11, the fixing member F31 is installed in the groove F110 through the rib F312 and covers a part of the pressing member F32. A plurality of screws (not shown in the figure) pass through the plurality of fixing holes F311 and the plurality of mounting holes F113 in sequence, thereby fixing the fixing member F31 and the bracket F11 to the box body to prevent the control mechanism F30 and the power receiving unit 21 from falling off from the processing box 1.

[0340] The following describes the process of engagement and disengagement between the power receiving unit of the processing cartridge and the driving unit of the electronic imaging device (for the convenience of understanding the action of the pressing member F32 in the bracket F11, the fixing member F31 in the control mechanism F30 is in the Figure 25 not shown).

[0341] like Figure 25 and Figure 26 As shown, when the processing box 1 is not installed in the electronic imaging device, the elastic force of the second elastic member F80 causes the pressing member F32 to be in an extended state, and the pressing portion F323 of the pressing member F32 abuts against the protrusion F51 of the movable member F50, and applies a force toward the inside of the photosensitive drum 20 to the protrusion F51, so that the movable member F50 together with the power receiving unit 21 overcomes the elastic force of the first elastic member F90 and is compressed in the bracket F11, and the engaging portion F213 of the power receiving unit 21 does not extend from the bracket F11. At this time, the power receiving unit 21 is in the initial position.

[0342] like Figure 27 and Figure 28As shown, when the processing box 1 is installed into the electronic imaging device along the installation direction X6, the front end of the pressing member F40 abuts against the retaining wall 1081. As the processing box 1 continues to be installed, the pressing member F40 is inserted into the opening of the retaining wall 1081 and contacts the driving unit 1080. Since the front end of the processing box 1 moves downward and drives the pressing member F40 to move downward, the front end of the pressing member F40 presses down the driving unit 1080, causing the driving unit 1080 to move downward to be basically coaxial with the power receiving unit 21 to receive power. At the same time, as the pressing member F40 presses down the drive unit 1080, the pressing member F32, which abuts the protrusion F51, moves to a position where it contacts the retaining wall 1081. As the process cartridge is installed, the pressing member F32, acting upon the retaining wall 1081, overcomes the elastic force of the second elastic member F80 and moves in a direction opposite to the installation direction X6. At this point, the pressing member F32 no longer abuts the protrusion F51. The movable member F50, freed from the force of the pressing member F32, drives the power receiving unit 21 in the direction Y6 (i.e., away from the interior of the photosensitive drum). Simultaneously, the lower surface F54 of the movable member F50 no longer contacts the support portion F61 of the hub F60, and the power receiving unit 21 is now in the second position. Once the process cartridge is properly installed in the electronic imaging device, the pressing member F40 successfully aligns the drive unit 1080, and the power receiving unit 21 extends from the bracket F11 and engages with the drive unit 1080, thereby transmitting the driving force.

[0343] like Figure 29 As shown, when the processing box is used up and needs to be taken out from the electronic imaging device, the user can first pull out one end 1B of the processing box 1, so that the one end 1B of the processing box is tilted relative to the other end 1A of the processing box 1 (that is, the end where the power receiving unit 21 is located). When the processing box 1 is in a relatively tilted state, a certain gap space is generated between the power receiving unit 21 and the driving unit 1080. At this time, the pressing member F32 gradually moves along the X6 direction to a position where it re-engages with the protrusion F51, so that the movable member F50 drives the power receiving unit 21 to move in a direction pointing to the inside of the photosensitive drum 20. Finally, the power receiving unit 21 and the driving unit 1080 are disengaged, so that the processing box is successfully taken out of the electronic imaging device.

[0344] In some embodiments, the first end 1A of the process cartridge 1 is further provided with a guide surface F44, located to the rear side of the pressing member F40. The guide surface F44 prevents interference with the block-shaped protrusion D1010 during installation and removal of the process cartridge 1. Alternatively, the guide surface F44 can be configured as an inclined or curved surface that slopes toward the rear of the process cartridge. During installation and removal of the process cartridge, the block-shaped protrusion D1010 can slide against the surface of the guide surface F44, thereby preventing interference between the process cartridge and the block-shaped protrusion D1010, which could affect the installation of the process cartridge.

[0345] In some embodiments, the first end 1A of the process cartridge 1 is further provided with a guided portion F41. Specifically, the guided portion F41 may protrude outward from the end surface of the process cartridge so as to abut against a guide rail on the electronic imaging device during installation of the process cartridge, thereby guiding installation of the process cartridge. Alternatively, the guided portion F41 may be provided at other locations on the first end, as long as it can abut against and be guided by the guide rail on the electronic imaging device. Of course, in some embodiments, the guided portion F41 may be omitted.

[0346] Example 7

[0347] Based on the sixth embodiment, this embodiment provides another processing box.

[0348] like Figures 30 to 34 As shown, the process cartridge 1 includes a bracket G11, a photosensitive drum 20, a pressing member G40, a movable member G50, a supporting member G60, a power receiving unit G21, and an elastic member (not shown). It should be noted that the pressing member G40 in this embodiment has the same structure as the pressing member in the sixth embodiment. The pressing member G40 is fixed to the cartridge body and is located at the same end of the cartridge body as the power receiving unit G21.

[0349] Specifically, the power receiving unit G21 includes a cylindrical main body G212, one end of which is provided with an engagement portion G211 for engaging with the drive unit 1080. A plurality of connecting posts G213 are evenly spaced along the circumference of the main body G212. The number of connecting posts G213 is not limited; in this embodiment, there are three connecting posts G213. A gear portion is provided on the outer circumference of the movable member G50. Specifically, the movable member G50 also has a stopper G51, one surface of which is provided with a plurality of protrusions G52. The support member G60 is a cylindrical structure, and the support member G60 includes an upper cylinder G63 and a lower cylinder G64. The radius of the upper cylinder G63 is smaller than the radius of the lower cylinder G64, and the outer circumferential surface of the upper cylinder G63 is provided with a plurality of grooves G65 corresponding to the number of protrusions G52. The lower cylinder G64 is also provided with a support surface G61, and the support surface G61 is provided with a plurality of outward protruding inclined surfaces G62 corresponding to the number of protrusions G52.

[0350] like Figure 36 and Figure 37As shown, the connection relationship between the above-mentioned parts is as follows: the movable member G50 is mounted on the upper tube G63 of the support member G60 to be installed in the support member G60, the protrusion G52 is located on the support surface G61, and the movable member G50 can rotate and translate relative to the support member G60. The power receiving unit G21 is inserted into the movable member G50 and the support member G60, and the connecting column G213 is inserted into the groove G65. At the same time, the connecting column G213 is supported by the limit portion G51 of the movable member G50, thereby movably connecting the power receiving unit G21 and the support member G60, and the power receiving unit G21 can move together with the movable member G50. An elastic member (not shown) is arranged between the power receiving unit G21 and the support member G60, with one end of the elastic member abutting the power receiving unit G21 and the other end abutting the bottom surface inside the support member G60.

[0351] Furthermore, if Figure 35 As shown, to enable the power receiving unit G21 to translate along the axis of the photosensitive drum 20, the process cartridge 1 further includes a control mechanism G30. The control mechanism G30 cooperates with the movable member G50 to control the rotation of the movable member G50, thereby enabling the power receiving unit G21 to be displaced axially along the photosensitive drum 20. Specifically, the control mechanism G30 includes a connecting member G31, an intermediate gear G32, and a drive gear G80. The intermediate gear G32 is connected to the connecting member G31. In this embodiment, the intermediate gear G32 and the connecting member G31 are integrally formed. The drive gear G80 can be sleeved onto the other end of the connecting member G31. Optionally, the drive gear G80 can also be a rubber wheel. When the control mechanism G30 is installed on the box body, the connecting part G31 is provided with an intermediate gear G32 at one end thereof arranged close to the developing roller 30, and the intermediate gear G32 can engage with the gear portion of the movable part G50. Through the rotation of the control mechanism G30, the movable part G50 can be driven together with the power receiving unit G21 to move in a direction away from the inside of the photosensitive drum 20.

[0352] like Figure 36 and Figure 37 As shown, when the processing box is not installed in the electronic imaging device, the power receiving unit G21 is located in the bracket G11, and the power receiving unit G21 and the movable part G50 are arranged close to the photosensitive drum 20. At this time, the power receiving unit G21 is in the initial position.

[0353] like Figures 38 to 39As shown, when the processing box 1 is installed in the electronic imaging device, the front end of the pressing member G40 abuts against the retaining wall 1081. As the processing box 1 continues to be installed, the pressing member G40 is inserted into the opening of the retaining wall 1081 and contacts the drive unit 1080. When the front end of the processing box 1 moves downward and drives the pressing member G40 fixed relatively to the processing box to move downward, the front end of the pressing member G40 presses down the drive unit 1080, causing the drive unit 1080 to move downward to be basically coaxial with the power receiving unit G21 to receive power. And in the plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member G40 and the projection of the photosensitive drum do not overlap at all. At the same time, in the process of the pressing member G40 pressing down the drive unit 1080, as the drive unit 1080 moves downward, it contacts the drive gear G80. Since the outer circumference of the drive unit 1080 is provided with an external gear portion (see Figure 1 ), the external gear portion has a helical gear structure. The external gear portion of the drive unit 1080 meshes with the drive gear G80, allowing the drive gear G80 to transmit the received driving force to the intermediate gear G32. The intermediate gear G32 then transmits the driving force to the gear portion of the meshing movable member G50, thereby driving the movable member G50 to rotate. As the movable member G50 rotates, the protrusion G52 moves to a position abutting the inclined surface G62 and moves along the inclined surface G62 from its low position to its high position, causing the movable member G50 and the power receiving unit G21 fixedly connected to the movable member G50 to move in a direction away from the photosensitive drum 20, thereby causing the power receiving unit G21 to extend from the bracket G11. At this time, the power receiving unit G21 is in the second position, ultimately successfully meshing with the drive unit 1080 to achieve the transmission of driving force. Because the control mechanism G30 is not connected to the developing roller 30, the control mechanism G30 cannot transmit the driving force received from the drive unit 1080 to the developing roller 30. Therefore, a photosensitive drum gear G25 is provided on the end of the photosensitive drum 20 away from the movable part G50, and a developing roller gear G26 is provided on the end of the developing roller 30 away from the movable part G50. The developing roller gear G26 is engaged with the photosensitive drum gear G25, so that the movable part G50 can transmit the driving force received from the power receiving unit G21 to the photosensitive drum gear G25, and then transmit it to the developing roller gear G26 engaged with the photosensitive drum gear G25, thereby driving the developing roller 30 to rotate.

[0354] The method of removing the processing box from the electronic imaging device in this embodiment is similar to that in the sixth embodiment. The relative tilting of the processing box during the removal process makes it smoother for the user to remove the processing box from the electronic imaging device.

[0355] refer to Figure 37As shown, in some embodiments, an elastic return member G27 is provided at one end of the power receiving unit G21 away from the engagement portion G211. This elastic return member G27 may be a compression spring. When the drive unit 1080 stops rotating, the elastic force of the elastic return member G27 is greater than the force acting between the drive unit 1080 and the power receiving unit G21. Therefore, the elastic return member G27 can pull the power receiving unit G21 back to its initial position. This structural arrangement allows the process cartridge to be removed smoothly without tilting the cartridge.

[0356] Example 8

[0357] The shape and structure of the processing box 1 and the electronic imaging device of this embodiment are basically the same as those of the processing box and the electronic imaging device of the fourth embodiment. The similarities are not repeated here, and only the main differences are introduced below.

[0358] like Figures 41a to 42 As shown, the electronic imaging device includes a main assembly H100, in which a process cartridge 1 is removably accommodated. The main assembly H100 is provided with a first side wall H101 and a second side wall H102 in the longitudinal direction Y of the process cartridge 1. The first side wall H101 and the second side wall H102 are each provided with a guide rail for guiding the installation of the process cartridge 1. Specifically, the second side wall H102 is provided with a first guide rail H103 and a second guide rail H104 for guiding the installation of the process cartridge 1. The first guide rail H103 includes a first guide section H1031 and a second guide section H1032. The first guide section H1031 and the second guide section H1032 are continuous. In the installation direction of the process cartridge 1 in the electronic imaging device, the second guide section H1032 is located below the first guide section H1031. In this embodiment, both the first guide section H1031 and the second guide section H1032 are inclined surfaces, and both the first guide section H1031 and the second guide section H1032 are inclined toward the rear of the process cartridge installation direction. In the normal use state of the electronic imaging device placed on a horizontal surface, the angle between the second guide section H1032 and the horizontal surface is greater than the angle between the first guide section H1031 and the horizontal surface. Alternatively, the first guide section H1031 and the second guide section H1032 can also be configured as curved surfaces, or one can be an inclined surface and the other can be a curved surface. Alternatively, the first guide section H1031 and the second guide section H1032 can also be guide grooves arranged at an angle. In this embodiment, the rear half of the first guide rail H103 forms a recessed portion, that is, the second guide section H1032 is recessed relative to the first guide section H1031.

[0359] The second guide rail H104 is positioned adjacent to the retaining wall 1081, with its downstream end extending above the retaining wall 1081. In the installation direction of the process cartridge 1, the second guide rail H104 is positioned downstream of the first guide segment H1031. Specifically, the second guide rail H104 includes a third guide segment H1041, a fourth guide segment H1042, and a fifth guide segment H1043. These segments are arranged sequentially along the installation direction of the process cartridge 1, and are continuous with one another. In this embodiment, the third guide segment H1041, the fourth guide segment H1042 and the fifth guide segment H1043 are constructed as inclined surfaces, and the angles between the third guide segment H1041, the fourth guide segment H1042 and the fifth guide segment H1043 and the horizontal plane increase successively, and the fourth guide segment H1042 and the fifth guide segment H1043 are arranged close to the retaining wall 1081.

[0360] The first side wall H101 is provided with a third guide rail H1012 for guiding the installation and positioning of the process cartridge 1. In this embodiment, the third guide rail H1012 is composed of an inclined surface. Alternatively, the third guide rail H1012 can also be composed of a curved surface, or the third guide rail H1012 can also be a guide groove.

[0361] Furthermore, the electronic imaging device also includes a first identification mechanism and a second identification mechanism for preventing the process cartridge 1 from being incorrectly installed. The first identification mechanism is disposed on the second side wall H102 of the electronic imaging device, and the first identification mechanism includes a first movable component H1033. The first movable component H1033 is movable between a first position that restricts the installation of the process cartridge 1 and a second position that allows the installation of the process cartridge 1. Specifically, the first movable component H1033 is supported on the second side wall H102 of the main assembly. The first movable component H1033 is rotatable about a rotation axis parallel to the installation direction X of the process cartridge 1. When in the first position, the first movable component H1033 protrudes from the second side wall H102 to interfere with the process cartridge 1 installed in the main assembly H100 and restrict the installation of the process cartridge 1. In this position, the process cartridge 1 is blocked by the first movable component H1033 and cannot be installed in place, thereby being unable to receive driving force from the electronic imaging device. In the second position, the first movable component H1033 is retracted relative to the first position, that is, deflected closer to the second side wall H102. In this position, the process cartridge 1 can be installed in place, so that the process cartridge can receive driving force from the electronic imaging device and perform normal printing operations. "Installed in place" here means that the process cartridge 1 can normally receive driving force and perform printing operations after installation. In this embodiment, the first movable component H1033 is a bump.

[0362] The second identification mechanism is located on the first side wall H101 of the electronic imaging device. It is constructed as a swing arm H1013 that can swing about a rotation axis parallel to the length direction Y of the process cartridge 1. A push-receiving portion H1014 is located above the swing arm H1013, protruding along the length direction Y of the process cartridge. In the installation direction of the process cartridge 1, the free end of the swing arm H1013 is located downstream, while the end hinged to the rotation axis is located upstream. In other words, the swing arm is tilted as a whole, and the swing arm H1013 can extend to the third guide rail H1012. During the installation process of the process cartridge 1, the swing arm H1013 must be pushed to rotate in order to successfully install the process cartridge 1; otherwise, installation will fail.

[0363] like Figure 43-45 As shown, the processing box 1 of this embodiment also includes a first guided portion H41 and a second guided portion H42. The first guided portion H41 and the second guided portion H42 are both arranged at the first end 1A of the processing box 1 (the end where the power receiving unit is arranged). Specifically, the first guided portion H41 is arranged on the photosensitive drum frame and is located on the upstream side of the photosensitive drum 20 in the installation direction of the processing box. In this embodiment, the first guided portion H41 is configured as a protrusion, which protrudes outward from one end of the processing box 1 along the longitudinal direction Y of the processing box 1 so that it can abut against the first guide rail H103 in the early stage of the installation process to guide the installation of the processing box. Alternatively, the first guided portion can also be the lower outer edge of the processing box housing. The second guided portion H42 is capable of abutting and cooperating with the second guide rail H104 at a later stage during the installation of the process cartridge 1. In this embodiment, the second guided portion H42 is located above the first guided portion H41 when the process cartridge 1 is installed, and is located downstream of the first guided portion H41 in the installation direction of the process cartridge, and is fixedly connected to the pressing member H40. Preferably, the second guided portion H42 is integrally formed with the pressing member H40, and is located above the pressing member H40 in the installation direction of the process cartridge 1. Preferably, the second guided portion H42 is located above the outer periphery of the photosensitive drum 20. Preferably, the second guided portion H42 is configured as a protrusion that protrudes outward from one end of the process cartridge 1 along the length of the process cartridge 1.

[0364] like Figure 44 As shown, the process cartridge 1 further includes a third guided portion H43, which is disposed at the second end 1B of the process cartridge 1 (the end opposite the power receiving unit). The third guided portion H43 is capable of abutting and cooperating with the third guide rail H1012 during installation of the process cartridge 1. Preferably, in this embodiment, the third guided portion H43 is configured as a protrusion that protrudes outward from one end of the process cartridge 1 along the length direction of the process cartridge 1. More preferably, the third guided portion H43 is disposed at one end in the axial direction of the photosensitive drum 20 and is configured as a circular guide post. The third guided portion H43 may also be disposed on an end cover (not shown).

[0365] Furthermore, the process cartridge 1 includes a first guide surface H44, which is disposed at the first end 1A of the process cartridge 1. This first guide surface H44 is used to guide the first movable component H1033 to prevent interference with the first movable component H1033 during disassembly of the process cartridge 1. This ensures that the first movable component H1033 can be smoothly disengaged from the first guide surface H44. Overall, the first guide surface H44 is located above the process cartridge 1. In the installation direction of the process cartridge 1, the first guide surface H44 is located upstream of the photosensitive drum 20 and upstream of the abutment between the pressing member H40 and the drive unit 1080. In this embodiment, the first guide surface H44 is configured to face forward and upward, but it can also be configured as a curved surface. When the process cartridge 1 is installed in the electronic imaging device, the first guide surface H44 is pressed against the first movable component H1033 to restrict rotation of the process cartridge 1 and thereby position the process cartridge 1. In this case, the first guide surface H44 can also be configured as a non-inclined surface structure. Compared to a non-inclined surface structure, the inclined first guide surface H44 can prevent interference between the process cartridge 1 and the first movable component H1033 during installation and removal, thereby preventing any interference with the installation and removal operations of the process cartridge 1.

[0366] In order to prevent the pressing member H40 from interfering with the retaining wall 1081 when the processing cartridge 1 is disassembled, the pressing member H40 further includes a guiding pressing surface H45, which is provided on the lower side of the pressing member H40. By providing the guiding pressing surface H45, the pressing member H40 can be prevented from interfering with the retaining wall 1081 when the processing cartridge 1 is disassembled, thereby preventing the pressing member H40 from interfering with the retaining wall 1081, thereby affecting the disassembly of the processing cartridge 1. When the processing cartridge 1 is installed in the electronic imaging device, the pressing member H40 extends into the retaining wall 1081 and presses the driving unit 1080, so that the driving unit 1080 moves from the initial tilted position to the position aligned with the supporting member 1085 (such as Figure 2 The position coincides with the axial direction of the photosensitive drum (as shown). Furthermore, on a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member is located outside the projection range of the photosensitive drum. The guiding pressing surface H45 on the pressing member H40 abuts against the outer wall of the retaining wall 1081. Specifically, because the pressing member H40 extends into the opening 10813 provided on the upper side of the retaining wall 1081, the guiding pressing surface H45 abuts against the outer edge 10814 of the opening 10813.

[0367] Furthermore, the processing box 1 also includes a first pressing surface H46 and a second pressing surface H47. The first pressing surface H46 and the second pressing surface H47 are located at the second end 1B of the processing box 1, and the first pressing surface H46 and the second pressing surface H47 are higher than the upper surface of the processing box. The first pressing surface H46 is used to unlock the rocker arm H1013 during the installation of the processing box, and the second pressing surface H47 is used to unlock the rocker arm H1013 during the removal of the processing box 1 from the electronic imaging device. In the installation and disassembly direction of the processing box 1, in the installation and disassembly direction of the processing box 1, the second pressing surface H47 and the first pressing surface H46 are distributed in steps, that is, there is a height difference between the two, and the second pressing surface H47 is located on the upper side of the first pressing surface H46. In this embodiment, the first pressing surface H46 and the second pressing surface H47 are configured as curved surfaces or inclined surfaces. Specifically, the first pressing surface H46 and the second pressing surface H47 are both inclined toward the rear of the installation direction of the processing box 1. Reference Figure 51 As shown, preferably, the height difference between the first pressing surface H46 and the second pressing surface H47 is in the range of H1≤H≤H2, with H1 being 3.37 mm and H2 being 10.05 mm. Preferably, the height difference between the first pressing surface H46 and the surface of the rocker arm H1013 that cooperates is in the range of H3, preferably less than 2.72 mm, and the height difference between the second pressing surface H47 and the surface of the rocker arm H1013 that cooperates is in the range of H4, preferably less than 4.06 mm. Within the above range, the cooperation effect with the rocker arm is better.

[0368] Next, combine Figures 42-49 The specific operation process of installing the processing box 1 to the electronic imaging device and the matching process of various components are introduced in detail.

[0369] During the installation of the processing box, the stage before the second guided portion H42 is not supported by the second guide rail H104 is called the early stage (or front installation section) of the installation process of the processing box 1, and the stage when the second guided portion H42 is supported by the second guide rail H104 is called the late stage (or late installation section) of the installation process of the processing box 1.

[0370] In the early stage of installing the processing cartridge, the user holds the handle of the processing cartridge 1 (not shown in the figure) and places the processing cartridge into the electronic imaging device, and makes the first guided portion H41 and the third guided portion H43 respectively embed into the first guide rail H103 and the third guide rail H1012 and pushes the processing cartridge 1 along the installation direction of the processing cartridge 1. At this time, the first guided portion H41 of the processing cartridge 1 can abut against the first guide section H1031 of the first guide rail H103, and the third guided portion H43 abuts against the third guide rail H1012, that is, the processing cartridge is supported by the first guide section H1031 of the first guide rail H103 and the third guide rail H1012. As the processing cartridge 1 moves forward along the guide rails in the processing cartridge installation direction X direction (such as Figure 41bWhen the first guided portion H41 moves to the end of the first guide segment H1031 of the first guide rail H103 or moves to the second guide segment H1032 (that is, when it reaches the recessed position), the second guided portion H42 abuts against the third guide segment H1041 of the second guide rail H104, and the first guided portion H41 also disengages from the abutment with the first guide rail H103, and the first end 1A of the processing box is lifted.

[0371] In the later stage of installing the process cartridge, the second guided portion H42 abuts against the third guide section H1041, and the third guided portion H43 abuts against the third guide rail H1012, and the process cartridge is supported by the second guide rail H104 and the third guide rail H1012. As the processing box 1 continues to move forward in the installation direction X of the processing box, the second guided portion H42 abuts against the third guide section H1041 and enters the fourth guide section H1042; during the movement of the second guided portion H42 abutting against the fourth guide section H1042, the processing box 1 rotates along the W direction with the abutment point between the second guided portion H42 and the fourth guide section H1042 and the abutment point between the third guided portion H43 and the third guide rail H1012 as the fulcrum, that is, the processing box 1 moves forward while rotating and moving along the guide rail, and the pressing member H40 is lifted along the W direction. This movement method can avoid interference between the pressing member H40 and the retaining wall 1081; during this process, the processing box can move forward under the action of external force or under the action of its own gravity.

[0372] As the process cartridge 1 continues to move forward in the process cartridge installation direction (direction X), the second guided portion H42 eventually disengages from the second guide rail H104 at the fifth guide segment H1043. The pressing member H40 extends into the opening 10813 above the retaining wall 1081, pressing the drive unit 1080. The guiding pressing surface H45 presses against the outer edge 10814 of the opening 10813, thus completing the installation of the process cartridge 1. The first movable component H1033 presses against the first guide surface H44, inhibiting the rotation of the process cartridge 1 and ensuring a more stable state. During this process, the process cartridge can advance either under the influence of an external force or under the influence of its own gravity.

[0373] Combine Figure 43-45 During installation of the process cartridge 1, the hollowed-out relief portion H48 provided at the first end 1A of the process cartridge 1 prevents interference with the first movable component H1033. During installation, the first pressing surface H46 provided at the second end 1B of the process cartridge 1 first contacts the pushed portion H1014 on the upper side of the swing lever H1013, pushing the swing lever H1013 to rotate, thereby preventing the third guided portion H43 from being blocked by the free end of the swing lever H1013.

[0374] When removing the process cartridge 1, the user grasps the handle of the process cartridge 1 and removes the process cartridge 1 from the electronic imaging device in the direction opposite to the process cartridge installation direction X. It should be noted that, in the early stages of process cartridge 1 removal, the second guided portion H42 abuts against and moves along the second guide rail H104. In the later stages of removal, the second guided portion H42 is supported by the first guided portion H41 of the process cartridge 1, i.e., the second guided portion H42 abuts against and moves along the first guide rail H103, while the third guided portion H43 is always supported by the third guide rail H1012.

[0375] Combine Figures 49 and 50 During the removal of the processing cartridge, especially when the user just starts to pull out the processing cartridge, the first guide surface H44 is pressed by the first movable component H1033, and the rotation process of the processing cartridge 1 in the opposite direction along the W direction is suppressed, thereby reducing the depth of the pressing member H40 embedded in the opening 10813, thereby reducing or avoiding the interference of the pressing member H40 with the retaining wall 1081 when taking it out. In addition, since the pressing member H40 is provided with a guiding pressing surface H45, the disassembly of the processing cartridge 1 is smoother.

[0376] When the second guided portion H42 abuts against the fourth guiding section H1042, the pressing member H40 has retracted from the opening portion 10813, and the processing box can be rotated in the opposite direction of the W direction to a preset angle under the action of external force. The second pressing surface H47 of the processing box 1 first touches the pushed portion H1014 of the rocker arm H1013 and pushes the rocker arm H1013 to rotate, thereby avoiding the third guided portion H43 being blocked by the free end of the rocker arm H1013 during the process of disassembling the processing box 1 from the electronic imaging device.

[0377] Embodiment 9

[0378] The processing box and the electronic imaging device of this embodiment are basically the same in shape and structure as those of the processing box and the electronic imaging device of the eighth embodiment. Parts described in the eighth embodiment will not be repeated in this embodiment. Only the differences from the above-mentioned eighth embodiment will be explained below.

[0379] like Figure 52a As shown, in the example of the electronic imaging device of this embodiment, a fourth guide rail 1105 is provided on the second side wall 1102 of the main assembly 1100 of the electronic imaging device. Preferably, the fourth guide rail 1105 is at least partially located below the second guide rail 1104 and closer to the first side wall 1101 of the main assembly 1100 relative to the second guide rail 1104 along the Y direction. In the installation direction of the process cartridge, the fourth guide rail 1105 is at least partially located upstream of the second guide rail 1104. In this embodiment, the fourth guide rail 1105 is inclined toward the rear of the main assembly 1100. The fourth guide rail 1105 can be configured as an inclined surface, a curved surface, or a guide groove.

[0380] like Figure 52b As shown, the first side wall 1101 is provided with a third guide rail 11012 for guiding the installation and positioning of the processing cartridge 1. In this embodiment, the third guide rail 11012 is composed of an inclined surface; alternatively, the third guide rail 11012 can also be composed of a curved surface or a guide groove. Preferably, the third guide rail 11012 includes a sixth guide segment 11015 and a seventh guide segment 11016. In the installation direction of the processing cartridge 1 (X direction, as shown in FIG. 1 ), the third guide rail 11012 is provided with a sixth guide segment 11015 and a seventh guide segment 11016. Figure 41b ), the seventh guide segment 11016 is located downstream of the sixth guide segment 11015. Preferably, the seventh guide segment 11016 is parallel to the bottom surface of the main assembly 1100, and the sixth guide segment 11015 is connected to the seventh guide segment 11016 and tilted toward the rear side of the main assembly 1100.

[0381] like Figure 53 As shown, this embodiment is not provided with the first guided portion relative to the eighth embodiment. The processing box in this embodiment further includes a fourth guided portion I41, which is provided on the lower side of the processing box 1 (located downstream of the processing box 1 when the processing box 1 is installed in the electronic imaging device) and is located at the first end 1A of the processing box. Preferably, the fourth guided portion I41 is provided on the end cover I102b of the developing frame I101b. Preferably, the fourth guided portion I41 is configured as an arcuate surface, and when the processing box 1 is installed in the electronic imaging device, the fourth guided portion I41 is located below the second guided portion I42. In the installation direction of the processing box 1, the fourth guided portion I41 is located upstream of the second guided portion I42. Alternatively, the fourth guided portion I41 may also be provided at other positions at the end of the developing frame I101b or be configured as a component extending from other positions of the processing box, as long as it can cooperate with the fourth guide rail I105 during the installation process.

[0382] As in Example 8, the second end 1B of the processing box 1 of this embodiment is also provided with a first pressing surface 146 for unlocking the rocker arm 11013 (second identification mechanism) during the installation process, and a second pressing surface 147 for unlocking the rocker arm 11013 during the removal of the processing box 1 from the electronic imaging device. The first pressing surface 146 and the second pressing surface 147 are higher than the upper surface of the processing box. During the installation and removal of the processing box, the second pressing surface 147 and the first pressing surface H46 are distributed in steps, that is, there is a height difference between the two, and the second pressing surface H47 is located on the upper side of the first pressing surface H46. In this embodiment, the first pressing surface 146 and the second pressing surface 147 are configured as curved surfaces or inclined surfaces. Specifically, the first pressing surface 146 and the second pressing surface 147 are inclined in the opposite direction of the processing box installation direction (X direction).

[0383] In some possible embodiments, in this embodiment, the processing cartridge 1 further includes a limiting portion 1471. The limiting portion 1471 can limit the position of the processing cartridge 1 when the processing cartridge is removed to prevent the processing cartridge 1 from excessively rotating and causing an unsmooth removal of the processing cartridge. For example, in some embodiments, the processing cartridge may rotate as a whole during removal, and rotation of the processing cartridge 1 beyond a certain range will affect the removal process. Therefore, it is necessary to limit the movement of the processing cartridge 1 during removal to prevent the processing cartridge from rotating excessively. Preferably, because the limiting portion 1471 is provided on the second pressing surface 147, the limiting portion 1471 is restricted by the rocker arm 11013 when the processing cartridge rotates, thereby limiting the rotation of the processing cartridge.

[0384] Next, combine Figures 52a to 59b The specific operation process of removing or installing the processing box 1 from or to the electronic imaging device and the cooperation process of each component with the electronic imaging device are introduced in detail.

[0385] During the installation of the processing box 1, the stage before the second guided portion I42 is not supported by the second guide rail I104 is called the early stage (or front installation section) of the installation of the processing box 1, and the stage when the second guided portion I42 is supported by the second guide rail I104 is called the late stage (or late installation section) of the installation of the processing box 1.

[0386] Before installing the process cartridge 1, refer to Figure 55 As shown, the user holds the handle of the processing box 1 (not shown in the figure), places the processing box into the electronic imaging device, and makes the fourth guided part I41 and the third guided part I43 respectively embed into the positions of the fourth guide rail I105 and the third guide rail I1012, and pushes the processing box 1 along the installation direction (X direction) of the processing box 1. At this time, the fourth guided part I41 of the processing box 1 can abut on the surface of the fourth guide rail I105, the second guided part I42 does not abut on the second guide rail I104, and the third guided part I43 can abut on the surface of the sixth guide section I1015 of the third guide rail I1012, that is, the processing box 1 can be supported by the fourth guide rail I105 and the third guide rail I1012, but not supported by the second guide rail I104. During this period, in some possible embodiments, the rocker arm I1013 is also unlocked to enable the processing box to be accurately installed; that is, the first pressing surface I46 first touches the rocker arm I1013 and pushes the rocker arm I1013 to swing from the locked position to the unlocked position, avoiding the third guided part I43 touching the rocker arm I1013 and causing installation interference.

[0387] As the process cartridge 1 continues to move forward along the guide rail toward the process cartridge installation direction X, Figure 56As shown, the second guided portion 142 abuts against the second guide rail 1104, and the fourth guided portion 141 disengages from the fourth guide rail 1105. When the process cartridge 1 enters the later stage of installation, the second guided portion 142 abuts against the third guide segment 11041, and the third guided portion 143 abuts against the surface of the third guide rail 11012 (specifically, it may abut against the surface of the sixth guide segment 11015). The process cartridge 1 is supported by the second guide rail 1104 and the third guide rail 11012. As the process cartridge 1 moves forward, the second guided portion 142 abuts against the third guide segment 11041 and enters the fourth guide segment 11042. Preferably, during the movement of the second guided portion I42 against the fourth guide segment I1042, the processing box 1 can rotate along the W direction with the contact point between the second guided portion I42 and the fourth guide segment I1042 and the contact point between the third guided portion I43 and the third guide rail I1012 as the fulcrum, that is, the processing box 1 moves forward while rotating and moving along the guide rail, and the pressing member I40 is lifted along the W direction. This movement method can avoid the pressing member I40 from interfering with the retaining wall 1081 in the forward direction; during this process, the processing box 1 can move forward under the action of external force, or it can move forward and rotate under the action of its own gravity.

[0388] refer to Figure 41b As shown, in some possible embodiments, as the process cartridge 1 continues to move forward in the process cartridge installation direction X, the second guided portion 142 eventually separates from the second guide rail 1104 at the fifth guide segment 11043, and the pressing member 140 extends into the opening 10813 above the retaining wall 1081 (as shown in FIG. Figure 41b As shown in FIG. 1 ), the driving unit 1080 is pressed in the middle, and the second guide surface 145 is pressed against the outer edge 10814 of the opening 10813 (as shown in FIG. Figure 41b The process cartridge 1 is now installed. The first movable component 11033 presses against the first guide surface 144 to inhibit rotation of the process cartridge 1, making it more stable. During this process, the process cartridge 1 can advance under the influence of external force or its own gravity.

[0389] In some possible embodiments, the second guided portion 142 of the processing box can be rotated along the W direction when it abuts against the third guiding section 11041 or the fifth guiding section 11043, so as to avoid interference and ensure smooth installation of the processing box.

[0390] In some possible embodiments, the installation process of the processing cartridge 1 further includes an installation end stage. In this embodiment, the installation process after the second guided portion 142 of the processing cartridge 1 is separated from the second guide rail 1104 is referred to as the installation end stage (or the last installation section). At the installation end stage, Figure 57As shown, the second guided portion 142 is separated from the second guide rail 1104, the free end of the pressing member 140 is pressed against the upper side of the retaining wall 1081, and the first end 1A of the processing box 1 is lifted by a preset distance (such as Figure 58 As the process cartridge 1 moves forward, the pressing member 140 extends into the opening 10813 above the retaining wall 1081, pressing the drive unit 1080. The first end 1A of the process cartridge also sinks downward as a whole. When the door cover of the imaging device is closed, the pressing member 140 is forced to rotate to a position where the axis of the retaining wall 1081 coincides with the axis of the retaining wall 1081. At this point, the power receiving unit provided on the process cartridge 1 engages with the drive unit 1080. Furthermore, on a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member is outside the projection range of the photosensitive drum.

[0391] The coordination process of the various components during the disassembly of the processing cartridge refers to the coordination process of the various components during the installation of the processing cartridge. This structural design can make the disassembly and installation of the processing cartridge smoother.

[0392] Specifically, when removing the process cartridge 1, the user grasps the handle of the process cartridge 1 and removes the process cartridge 1 from the electronic imaging device in the direction opposite to the process cartridge installation direction (X). In the early stages of process cartridge 1 removal, the user can lift the rear portion of the process cartridge when initially pulling the process cartridge, causing the process cartridge to rotate by a predetermined angle to reduce interference. As the process cartridge moves, the second guided portion 142 abuts against the second guide rail 1104 and moves along the second guide rail 1104. In some possible embodiments, the second pressing surface 147 first contacts the pushed portion 11014 of the swing lever 11013, pushing the swing lever 11013 from a locked position to an unlocked position, thereby preventing the third guided portion 143 from contacting the swing lever 11013 and thereby preventing interference with cartridge removal.

[0393] In the later stage of disassembly, it is supported by the fourth guided portion 141 of the processing box 1, that is, the fourth guided portion 141 abuts on the fourth guide rail 1105 and moves along the fourth guide rail 1105, while the third guided portion 143 is always supported by the third guide rail 11012.

[0394] In some possible embodiments, during the process of removing the processing cartridge, the processing cartridge may rotate, and the reasons for the rotation of the processing cartridge may be the pulling direction of the user or the special structural design of the processing cartridge. Figure 59a and Figure 59b As shown, when the third guided portion I43 moves from the seventh guide segment I1016 of the third guide rail I1012 to the intersection with the sixth guide segment I1015, the second pressing surface I47 touches the rocker arm I1013 and pushes the rocker arm I1013 to swing upward to unlock the rocker arm I1013.

[0395] As the process cartridge moves in the direction opposite to the process cartridge installation direction (X direction), the process cartridge can rotate along the W2 direction by a preset angle, the limiting portion 1471 abuts against the pushed portion 11014 of the swing arm 11013, and the swing arm 11013 swings upward to the upper limit position (for example, in some embodiments, the swing arm 11013 contacts the side wall or other limiting component of the electronic imaging device when at the upper limit position, and thus cannot continue to swing). Since the limiting portion 1471 abuts against the pushed portion 11014 of the swing arm 11013, the process cartridge cannot continue to rotate, thereby making the removal of the process cartridge smoother. In some embodiments, the provision of the limiting portion 1471 prevents the process cartridge from rotating excessively at the preset position, thereby preventing the pressing member 140 from interfering with the retaining wall or the side wall of the electronic imaging device.

[0396] In some possible embodiments, the limiting portion I471 abuts against the pushed portion I1014 of the rocker arm I1013 and places the rocker arm I1013 in the upper limit position, that is, when the third guided portion I43 is located in the sixth guide segment I1015, or when the third guided portion I43 is located at the intersection of the sixth guide segment I1015 and the seventh guide segment I1016. Of course, it can also be when the third guided portion I43 is located in the seventh guide segment I1016.

[0397] In some possible embodiments, during the installation or disassembly of the processing box 1, the fourth guided portion I41 may be supported by the fourth guide rail I105 and the second guided portion I42 may be supported by the second guide rail I104 at the same time, for example, during the transition process between the early and late stages of installation.

[0398] In some possible embodiments, during the installation or disassembly of the processing box 1, the second guided portion 142 may be supported by the second guide rail 1104 and the pressing member 140 may be supported by the retaining wall 1081 at the same time, for example, during the transition process between the late installation stage and the final installation stage.

[0399] In some possible embodiments, in the early stage of the installation of the processing box, since the fourth guided portion I41 of the processing box abuts against the surface of the fourth guide rail I105, and the third guided portion I43 abuts against the surface of the sixth guide section I1015 of the third guide rail I1012, that is, the processing box is supported by two fulcrums, it can deflect around these two fulcrums during the installation process, thereby avoiding interference with some structures in the electronic imaging device, making the installation of the processing box smoother.

[0400] Example 10

[0401] This embodiment is an improvement made on the basis of the eighth and ninth embodiments, and the similarities therewith are not repeated here. The following mainly introduces the main differences therewith.

[0402] refer to Figure 52a and Figure 52b As shown, the main component of the electronic imaging device also includes a fifth guide rail K1017. In this embodiment, the fifth guide rail K1017 is located between the first side wall I101 and the second side wall I102 of the main component I100 of the electronic imaging device and is configured as an inclined surface, and optionally a curved surface or a guide groove.

[0403] On the basis of the process cartridges provided in the eighth and ninth embodiments, the process cartridge in this embodiment further includes a fifth guided portion K41 that cooperates with the fifth guide rail K1017, while eliminating the first guided portion. Figure 60 As shown, the fifth guided portion K41 is arranged on the lower side of the processing box, specifically on the lower side of the developing frame 101b, so that it can be supported by the fifth guide rail K1017 during the process of installing or removing the processing box. Preferably, the fifth guided portion K41 is arranged at a position in the middle of the processing box, which is biased towards the second end 1B. Alternatively, the fifth guided portion K41 can also be arranged in the middle or first end 1A, as long as it can cooperate with the fifth guide rail K1017. The processing box of this embodiment is basically the same as the process of the eighth and ninth embodiments in the installation or removal process. The main difference is that in the early stage of the installation of the processing box 1 of this embodiment, the processing box is supported by the fifth guide rail K1017, that is, the fifth guided portion K41 cooperates with the fifth guide rail K1017.

[0404] In some possible embodiments, reference Figure 60 As shown, the processing box can retain the fourth guided portion I41 and the fifth guided portion K41 at the same time. In the early stage of installation or the late / final stage of disassembly of the processing box, the processing box is supported by the fourth guide rail I105 and the fifth guide rail K1017 at the same time, that is, in the early stage of installation or the late stage of disassembly of the processing box, the fourth guided portion I41 can abut against the fourth guide rail I105, and the fifth guided portion K41 can abut against the fifth guide rail K1017.

[0405] Example 11

[0406] This embodiment is an improvement made on the basis of the above-mentioned embodiment. The similarities are not repeated here. The main differences are mainly introduced below.

[0407] In this embodiment, the unlocking member L47 is configured to be movable relative to the box body, thereby increasing the flexibility of the processing box when installing and / or removing it from the electronic imaging device and reducing the possibility of interference during the installation and removal of the processing box.

[0408] Specifically, such as Figure 61As shown, in this embodiment, the process cartridge further includes an elastic member L47b disposed between the photosensitive drum frame 12 and the unlocking member L47. A predetermined movable space is defined between the unlocking member L47 and the photosensitive drum frame 12, enabling the unlocking member L47 to move in both the L direction and the opposite L direction. Preferably, the elastic member L47b may be a compression spring, a tension spring, or an elastic arm integrally formed with the unlocking member. When the first pressing surface L46 or the second pressing surface L47a of the unlocking member L47 contacts the rocker arm 11013 to unlock the process, the unlocking member L47 is able to overcome the elastic force of the elastic member L47b and move.

[0409] In some possible implementations, during the process of installing or removing the process cartridge to or from the electronic imaging device, the unlocking member L47 and the rocker arm I1013 (eg, Figure 59c As shown in the figure, the unlocking member L47 can always keep in contact with the rocker arm I1013 after touching and unlocking the rocker arm I1013, that is, when the processing box is installed in place, the unlocking member L47 is still in contact with the rocker arm I1013.

[0410] In some possible implementations, when the processing cartridge is installed in place, the unlocking member L47 is still in contact with the rocker arm I1013, and places the rocker arm I1013 in the unlocked position.

[0411] Example 12

[0412] This embodiment is a further improvement made on the basis of the above-mentioned embodiment, and the similarities therein are not repeated here. The following mainly introduces the improvements.

[0413] like Figure 62 As shown, the process cartridge includes a photosensitive drum 20 and a charging roller M20a, which are rotatably supported on a photosensitive drum frame. Figure 62 The projection of the process cartridge on a plane perpendicular to the photosensitive drum's rotation axis is shown. On the projection plane, the photosensitive drum's rotation center is Q1, the charging roller M20a's rotation center is Q2, the line passing through Q1 and Q2 is a1, and the line passing through Q1 and perpendicular to a1 is a2. The vertical distance from a point on the first pressing surface M46 to a1 is S1, the vertical distance from a point on the second pressing surface M47 to a1 is S2, the horizontal distance from a point on the first pressing surface M46 to a2 is S3, and the horizontal distance from a point on the second pressing surface M47 to a2 is S4. Generally, if S1, S2, S3, and S4 are too large or too small, it will affect the installation and removal of the process cartridge and its coordination with the rocker arm I1013.

[0414] In order to make the installation of the processing box smoother and the first pressing surface M46 and the second pressing surface M47 better match with the rocker I1013, preferably, 20mm≤S1≤35mm, 20mm≤S2≤40mm, 5mm≤S3≤35mm, and 40mm≤S4≤80mm.

[0415] Furthermore, the above technical solution is further optimized. If the values ​​of S1 and S3 are respectively: 25mm≤S1≤27mm, 18mm≤S3≤32mm, S1 and S3 meeting the above value requirements can ensure smoother installation of the process cartridge and better cooperation between the first pressing surface M46 and the rocker arm I1013.

[0416] The following is an example: Figure 63 The combination of the minimum value of S1 and the minimum value of S3 is shown. This structural design makes the processing box smoother during installation, and the first pressing surface M46 and the rocker arm I1013 have a better matching effect.

[0417] When 29 mm ≤ S2 minimum value ≤ 37.5 mm and 52 mm ≤ S4 minimum value ≤ 80 mm, the processing box can be taken out from the electronic imaging device more smoothly, and the cooperation effect between the second pressing surface M47 and the rocker arm I1013 is better.

[0418] The following is an example: Figure 64 The combination of the minimum value of S2 and the minimum value of S4 is shown. This structural design makes the processing box smoother during installation, and the first pressing surface 47 and the rocker arm I1013 cooperate better.

[0419] This embodiment is a further improvement made on the basis of the above-mentioned embodiment, and the similarities therein are not repeated here. The following mainly introduces the improvements.

[0420] like Figure 65 As shown, the process cartridge includes a photosensitive drum 20 and a charging roller M20a, Figure 65 The projection of the process cartridge onto a plane perpendicular to the rotation axis of the photosensitive drum is shown. On the projection plane, the rotation center of the photosensitive drum 20 is Q1, the rotation center of the charging roller M20a is Q2, the straight line passing through Q1 and Q2 is a1, and the straight line passing through Q1 and perpendicular to a1 is a2. The perpendicular distance from the free end of the pressing member M40 to a1 is S5, and the perpendicular distance from the free end of the pressing member M40 to a2 is S6.

[0421] To ensure smoother loading and unloading of the printer and to prevent interference between the pressing member and the retaining wall 1081, S5 that is too small / too large and / or S6 that is too large / too small will result in unsmooth loading and unloading of the printer and poor coordination with the drive unit 1080. For example, in some embodiments, if S5 is too large and / or S6 is too small, the drive unit 1080 may not be effectively pressed, i.e., the drive unit 1080 may not be properly forced to align. In some embodiments, if S5 is too small and / or S6 is too large, it may cause interference with the printer during loading or unloading of the printer.

[0422] After research and installation tests, it is preferred that when 8mm≤S5≤15mm and 4mm≤S6≤12mm are taken, the processing box is smoother when installed to or removed from the electronic imaging device, and can effectively press the drive unit 1080.

[0423] For example, Figure 66 When the selected values ​​of S5 and S6 are combined as shown, the processing cartridge is installed more smoothly, and the cooperation effect between the pressing member M40 and the driving unit 1080 is better.

[0424] Example 13

[0425] This embodiment provides a method for installing and removing the processing cartridge to and from an electronic imaging device based on the above-mentioned embodiment.

[0426] The following describes how to install and remove a process cartridge from an electronic imaging device. The process cartridge installation method specifically includes the following steps:

[0427] Step A1: Open the electronic imaging device door.

[0428] Step A2: Insert the process cartridge into the main assembly of the electronic imaging device along the installation direction.

[0429] Step A3: When the processing box moves to the late installation stage, the processing box is rotated along the W direction under the action of external force.

[0430] The method for disassembling the process cartridge from the electronic imaging device specifically includes the following steps:

[0431] Step B1: Open the electronic imaging device door.

[0432] Step B2: Pull the processing box in the opposite direction of installation, and the processing box rotates in the opposite direction of W by a preset angle under the action of external force.

[0433] Step B3: Continue pulling the process cartridge until the process cartridge is completely removed from the electronic imaging device.

[0434] Through the above steps, the installation and removal of the processing box can be smoother and unnecessary interference can be avoided.

[0435] Example 14

[0436] like Figures 67 to 69 As shown, there is an electronic imaging device 100 in which a process cartridge 1 can be detachably accommodated. The electronic imaging device 100 includes a main assembly N101 that can accommodate the process cartridge 1, a drive unit 1080, an openable and closable door cover 102, a connecting rod 103 that cooperates with the door cover 102, and a cylindrical cam N104 connected to the connecting rod 103.

[0437] The main assembly N101 is provided with a housing portion N105 for accommodating the process cartridge 1. The housing portion N105 is provided with a first side wall N106 and a second side wall N107 along the length of the process cartridge 1. The first side wall N106 and the second side wall N107 are respectively provided with guide rails N108 for guiding the installation or removal of the process cartridge 1. A drive unit 1080 is provided on the second side wall N107 of the housing portion N105 for transmitting driving force to the process cartridge 1.

[0438] In this embodiment, the drive unit 1080 is generally composed of three cylindrical bodies of varying diameters and sizes. The drive transmission portion N1082 of the drive unit 1080 is located on the small-diameter cylindrical body N1083 closest to the accommodating portion N105. The drive transmission portion N1082 can extend outside or retract relative to the second side wall N107 of the accommodating portion N105. The door cover 102 is rotatably mounted on the main assembly N101 to open and close the accommodating portion N105.

[0439] The connecting rod 103, the cam N104, and the drive unit 1080 are located on the same side of the accommodating portion N105, and the connecting rod 103, the cam N104, and the door cover 102 form a linkage relationship so as to lock or unlock the drive unit 1080 when the door cover 102 is closed or opened. When the drive unit 1080 is in a locked state, the drive unit 1080 cannot move and is in a tilted state, and the drive transmission portion N1082 is in a retracted position relative to the second side wall N107 of the accommodating portion N105. This position can prevent the drive transmission portion N1082 from interfering with the power receiving portion N211 of the process cartridge 1. When the drive unit 1080 is in an unlocked state, the drive unit 1080 can move under the action of an external force, that is, the drive unit 1080 can be changed from the tilted position to the straightened position (i.e., the non-tilted state) under the action of an external force and can extend from the second side wall N107 to stably transmit the driving force to the process cartridge 1.

[0440] like Figures 70 to 72As shown, the process cartridge 1 includes a cartridge body N10, a photosensitive drum 20, a developing roller 30, and a power receiving unit N21. In this embodiment, the cartridge body N10 includes a drum frame 12 for supporting the photosensitive drum 20 and a developing frame 11 for supporting the developing roller 30. The drum frame 12 and the developing frame 11 are connected to each other for relative rotation during operation and can move synchronously during installation of the process cartridge 1. The photosensitive drum 20 is mounted on the drum frame 12, and the developing roller 30 is mounted on the developing frame 11. The photosensitive drum 20 and the developing roller 30 are located at the front side of the process cartridge 1 along the installation direction, facing each other to facilitate development and other actions. In this embodiment, the cartridge body N10 also includes an end cap N202, which is located at one end of the drum frame 12. The power receiving unit N21 is arranged at the first end N50 of the box body N10, and the power receiving unit N21 includes a power receiving part N211, which can engage with the drive transmission part N1082 of the drive unit 1080 to receive the driving force, thereby driving the developing roller 30 and the photosensitive drum 20 to rotate.

[0441] Furthermore, in order to transform the driving unit 1080 from the tilted state of the initial position (in this state, the rotation axis NL1 of the driving unit 1080 is tilted relative to the rotation axis NL2 of the photosensitive drum 20) to the aligned state capable of engaging with the power receiving unit N21 (in this state, the rotation axis of the driving unit 1080 coincides with the rotation axis of the photosensitive drum 20), as shown in FIG. Figures 70 to 73 As shown, the process cartridge 1 further includes a pressing member N40, disposed at the first end N50, for applying a force to the drive unit 1080 to maintain the drive unit 1080 in a correct position. During installation of the process cartridge 1 in the electronic imaging device, the distance between the pressing member N40 and the axis of the photosensitive drum remains unchanged. Specifically, the pressing member N40 is fixedly mounted on the end cap N202, thereby forming a fixed connection with the drum frame 12.

[0442] like Figures 70 to 74 As shown, the pressing member N40 includes a mounting protrusion N401. In this embodiment, two mounting protrusions N401 are provided, one of which is located above the other. The end cap N202 is provided with a mounting hole corresponding to the mounting protrusion N401. During assembly, the mounting protrusion N401 engages with the mounting hole, securing the pressing member N400 to the end cap N202 or the drum frame 12, thereby enabling the pressing member N400 to move with the movement of the drum frame 12.

[0443] In the direction NL2 of the rotation axis of the photosensitive drum 20, the pressing member N40 is located outside the end of the power receiving portion N211 so that it can cooperate with the drive unit 1080 when the processing cartridge is installed. Furthermore, the pressing member N40 includes a cantilever N402 for pressing the drive unit 1080. The cantilever N402 is located on the front side of the pressing member N40, and on a plane perpendicular to the rotation axis of the photosensitive drum 20, the projection of the cantilever N402 at least partially overlaps with the projection of the photosensitive drum 20. In other words, at least a portion of the pressing member N40 is located within the range of the projected cross-section of the photosensitive drum 20. Alternatively, in other embodiments, the end cap can be eliminated and the pressing member N40 can be directly set on the drum frame 12, as long as the distance between the pressing member N40 and the rotation axis of the photosensitive drum 20 in the radial direction of the photosensitive drum 20 remains unchanged. Optionally, in the radial direction of the photosensitive drum 20 , the pressing member N40 may be positioned outside the circumferential outer surface of the photosensitive drum 20 or inside the photosensitive drum 20 , as long as it can cooperate with the driving unit 1080 .

[0444] Furthermore, the process cartridge 1 includes a guide protrusion N704 and a guided portion N70 that is movable relative to the drum frame 12. The guided portion N70 is disposed on the end cap N202 of the first end N50 and cooperates with a guide rail N108 located on the second side wall N107. In this embodiment, the guided portion N70 includes a first protrusion N701 protruding from the end surface of the end cap N202. The first protrusion N701 is capable of being inserted into the guide rail N108 on the second side wall N107 of the accommodating portion N105 when the process cartridge 1 is installed in the accommodating portion N105, thereby guiding the installation of the process cartridge 1. The guide protrusion N704 is disposed on an end of the cartridge body N10 away from the guided portion N70 and cooperates with the guide rail N108 on the first side wall N106 to guide the installation of the process cartridge 1. In this embodiment, the guide protrusion N704 is fixedly connected to the drum frame 12 and can move synchronously with the drum frame 12.

[0445] like Figure 73As shown, a groove N80 is provided on the end surface of the end cover N202. The groove N80 is provided with guide grooves N801 on the front side wall and the rear side wall respectively arranged relative to each other along the installation direction NY1 of the processing cartridge 1. The guide grooves N801 extend along the first direction. Correspondingly, the guided portion N70 includes a second protrusion N702 that cooperates with the guide groove N801. The second protrusion N702 is embedded in the guide groove N801, so that the guided portion N70 can move in the first direction relative to the drum frame 12. That is, the drum frame 12 of the processing cartridge 1 or the entire cartridge body N10 can move in the first direction relative to the guided portion N70. In other embodiments, the guide groove N801 can also be provided on the guided portion N70, and the second protrusion N702 that cooperates with the guide groove N801 can be provided on the drum frame 12. Optionally, the guided portion N70 can also be configured to be fixedly connected to the developing frame 11. The first direction is a direction intersecting the rotation axis NL2 of the photosensitive drum 20 and the installation direction NY1 of the process cartridge 1 .

[0446] In order to facilitate the cooperation between the guided portion N70 and the guide rail N108 or to facilitate the installation of the process cartridge 1, the guided portion N70 further includes an elastic member. In this embodiment, the elastic member is a compression spring N90, and there are two compression springs N90. The first protrusion N701 is provided with spring mounting parts N703 on both sides of the direction in which it moves relative to the drum frame 12, and two compression springs N90 are respectively provided on the upper and lower sides of the first protrusion N701. One end of the compression spring N90 is installed on the spring mounting part N703 of the guided part N70, and the other end abuts against the upper and lower side walls of the groove N80, so that the first protrusion N701 is supported by the compression spring N90 and maintained in a preset position. In this state, the first protrusion N701 has a preset distance from the upper and lower side walls of the groove N80 in the direction in which it moves relative to the drum frame 12 or the developing frame 11, so that when the processing box 1 is installed in the accommodating part N105, the first protrusion N701 can be located on the guide rail N108 of the second side wall N107, and the drum frame 12 or the developing frame 11 has sufficient moving space relative to the first protrusion N701. Alternatively, the elastic member may be eliminated or only one elastic member may be used, and the first protrusion N701 can still be movable relative to the drum frame 12 or the developing frame 11, or in other words, relative to the entire process cartridge 1. Alternatively, a plurality of guided portions N70 may be provided, or a similar guided portion N70 may be provided at the other end of the process cartridge 1, so that both ends of the process cartridge can move relative to the guide rail N108.

[0447] The following combination Figures 67 to 69 、 Figure 75 and Figure 76 The installation procedure of the process cartridge 1 is described.

[0448] When the processing box 1 is installed in the electronic imaging device 100 along the NY1 direction, the first protrusion N701 is embedded in the guide rail N108 of the second side wall N107 of the accommodating portion N105, and the guide protrusion N704 on the other side of the processing box 1 is embedded in the guide rail N108 of the first side wall 106, so that the processing box 1 is guided and installed along the NY1 direction. In this state, the first end N50 of the processing box 1 can move relative to the guided portion N70 in a direction intersecting the installation direction NY1 and the photosensitive drum axis NL2. As the processing cartridge 1 moves, the pressing member N40 fixed on the drum frame 12 gradually approaches the drive unit 1080. When the pressing member N40 contacts the circumferential outer surface of the small-diameter columnar body N1083 of the drive unit 1080, since the door cover 102 is not closed, the drive unit 1080 is in a locked state, and the pressing member N40 presses on the circumferential outer surface of the small-diameter columnar body N1083. The first end N50 of the developing cartridge 1 is lifted by a preset distance, and the cartridge body N10 (including the drum frame 12 and the developing frame 11) is displaced relative to the first protrusion N701, so that the processing cartridge can be installed smoothly, avoiding the inability to install due to interference between the pressing member N40 and the drive unit 1080 or interference with other components. Figure 75 As shown, the pressing member N40 is finally pressed on the circumferential outer surface of the small-diameter columnar body N1083 of the driving unit 1080. At this time, the driving unit 1080 is in an inclined state, the drive transmission part N1082 is in a retracted state relative to the second side wall N107 of the accommodating part N105, and the rotation axis NL1 of the driving unit 1080 and the rotation axis NL2 of the photosensitive drum 20 are in a crossed state.

[0449] When the door cover 102 is closed, the cam N104 releases the lock on the drive unit 1080. Since the cantilever N402 of the pressing member N40 presses on the drive unit 1080, the pressing member N40 applies a pressing force to the drive unit 1080. The drive unit 1080 receives the pressure and moves in the direction close to the power receiving unit 21 until the rotation axis NL1 of the drive unit 1080 coincides with the rotation axis NL2 of the photosensitive drum 20. In this state, when the electronic imaging device 100 is started, the power receiving unit 21 of the processing box 1 and the drive unit 1080 can engage and stably receive the driving force for rotation.

[0450] In this embodiment, since the pressing member N40 is fixedly arranged on the drum frame 12, its position relative to the axis NL2 of the photosensitive drum 20 remains unchanged, that is, the distance between the pressing member N40 and the axis NL2 of the photosensitive drum 20 does not change. The force applied by the pressing member N40 to the drive unit 1080 to align the drive unit 1080 can be the gravity of the processing box 1 itself, or it can be the force applied to the processing box 1 through the door cover 102 when the door cover 102 is closed. Alternatively, the pressing member N40 can also be other parts of the pressing drive unit 1080, as long as it can force it to align. Alternatively, the guided portion N70 can also be set at other positions on the box body N10, as long as it can move relative to the box body N10 and can avoid interference between the processing box 1 and the electronic imaging device when the processing box is installed. Alternatively, for an electronic imaging device in which the drive unit 1080 is unlocked, the guided portion N70 may be omitted because the pressing member N40 does not cause the process cartridge to be lifted when in contact with the drive unit 1080. Alternatively, the pressing member N40 may be positioned elsewhere to press the drive unit 1080, as long as it can be aligned.

[0451] This embodiment provides a pressing member on the processing box, which can make the process of contact and engagement between the power receiving unit and the driving unit smoother, greatly saving the time of contact and engagement between the power receiving unit and the driving unit, and improving the working efficiency of the processing box.

[0452] In some embodiments, the electronic imaging device is further provided with a biasing device, which is provided on the lower side of the driving unit 1080 and presses the driving unit 1080 so that the driving unit 1080 remains in an inclined state. Similarly, after the door cover 102 is closed on the developing cartridge of this embodiment, the pressing member N40 can resist the biasing force of the biasing device to straighten the driving unit 1080. The deformation of the electronic imaging device is not limited to this, and the biasing device can also be provided on the upper side of the driving unit 1080. Some electronic imaging devices also eliminate the cam N104. In an electronic imaging device of this structure, the processing cartridge 1 can be installed to the electronic imaging device without closing the door cover 102 to straighten the driving unit 1080.

[0453] Example 15

[0454] Figures 77-80 FIG. 1 is a schematic diagram of a partial structure of the electronic imaging device of this embodiment. Figure 77As shown, there is an electronic imaging device 100 in which a process cartridge 1 can be detachably mounted. The electronic imaging device 100 includes a main assembly O101 that can accommodate the process cartridge 1, a drive unit 1080, an openable and closable door O102, a connecting rod O103 that cooperates with the door O102, and a cylindrical cam O104 that cooperates with the door O102 via the connecting rod O103.

[0455] For the sake of convenience of description, along the installation direction OY1 of the processing box, the side where the drive unit is located is the front, and the side opposite to it is the rear; along the length direction OY2 of the processing box, the side where the drive unit is located is the right, and the side opposite to the right is the left.

[0456] The main assembly O101 is provided with a housing O105 for accommodating the process cartridge 1. The housing O105 is provided with a first side wall O106 and a second side wall O107 along the length of the process cartridge 1. The first side wall O106 and the second side wall O107 are each provided with a guide rail O108 for guiding the installation or removal of the process cartridge 1. A drive unit 1080 is provided on the second side wall O107 of the housing O105 for transmitting driving force to the process cartridge 1.

[0457] Furthermore, the electronic imaging device 100 also includes a cover 1081. The cover 1081 is disposed on the second side wall O107 and protrudes from the second side wall O107 along the length of the process cartridge toward the first side wall O106. The cover 1081 at least partially covers the drive unit 1080. Specifically, the cover 1081 includes a front plate 109a, a first side plate 109b, and a second side plate 109c. The first side plate 109b and the second side plate 109c are respectively connected to the front plate 109a. The front plate 109a is provided with a first hole 1090a for the drive unit 1080 to extend. The first hole 1090a is a circular hole that allows one end of the drive unit 1080 to extend through the first hole 1090a. The first side plate 109b is located on the upper side of the front plate 109a, the second side plate 109c is located on the rear side of the front plate 109a, and a second hole 1090b is formed between the first side plate 109b and the second side plate 109c, so that a portion of the driving unit 1080 can be exposed to the rear side of the cover 1081 through the second hole 1090b.

[0458] The door cover O102 is rotatably provided on the main assembly O101 so as to be able to open or close the accommodating portion O105. The door cover O102 is mounted on the main assembly O101 in a manner that rotates around a rotation axis, and is thereby able to open or close the accommodating portion O105 in a rotational manner. A cartridge pressing component O1020 is provided on each side of the door cover O102 along the axial direction of the rotation axis. Each of the two cartridge pressing components O1020 can move relative to the door cover O102 within a predetermined range. During the closing process of the door cover O102, the cartridge pressing component O1020 can push the force receiving portion O10a (described in detail later) provided on the processing cartridge 1 so that the processing cartridge can be installed and positioned in the main assembly O101 in a stable posture.

[0459] Furthermore, the connecting rod O103, the cam O104 and the driving unit 1080 are located on the same side of the accommodating portion O105, and the connecting rod O103, the cam O104 and the door cover O102 form a linkage relationship so as to be able to lock or unlock the driving unit 1080 when the door cover O102 performs a closing or opening action.

[0460] Figure 80 It is an exploded perspective view of the support structure of the drive unit. Figure 81 This is the structural diagram of the drive unit. Figure 80 and Figure 81 As shown, the electronic imaging device further includes a supporting side plate O82, which is disposed on the main assembly O101 and includes a first protrusion O82b and a second protrusion O82c. The drive unit 1080 includes a sliding portion 1080a, which is rotatably supported by a support hole O82a of the supporting side plate O82. Furthermore, the drive unit 1080 includes a cylindrical portion 1080b, a small-diameter portion 1080f, and a power output portion 1080e. The small-diameter portion 1080f is connected to the end of the cylindrical portion 1080b, and the diameter of the small-diameter portion 1080f is smaller than the diameter of the photosensitive drum. An input gear portion 1080d is provided on the outer surface of the cylindrical portion 1080b near one end of the small-diameter portion 1080f. The power output portion 1080e is disposed on the small-diameter portion 1080f and is configured to engage with the power receiving unit 21 of the process cartridge 1 to transmit driving force.

[0461] During the opening process of the door cover O102, the cylindrical cam O104 moves along with the door cover O102, resulting in the cylindrical cam O104 contacting the drive unit 1080. The drive unit 1080 moves along with the cylindrical cam O104 in the direction of arrow H. Then, the abutment surface 1080c of the drive unit 1080 contacts at least one of the first protrusion O82b or the second protrusion O82c of the support side panel O82, causing the drive unit 1080 to tilt in the direction of arrow N. When the door cover O102 is in the open state, the drive unit 1080 is in a tilted and locked state. In this state, the drive unit 1080 is in a retracted position relative to the front panel 109a, that is, the power output portion 1080e is retracted into the cover 1081.

[0462] When the door cover O102 is closed, the drive unit 1080 is in an unlocked state, and the drive unit 1080 can move under the action of external force, that is, it can change from a tilted state to a straightened state (that is, a non-tilted state) under the action of external force and can extend from the cover 1081 so as to be able to stably transmit driving force to the processing box 1.

[0463] The structure of the electronic imaging device is not limited to this. Some electronic imaging devices are also provided with a biasing device, which is located on the lower side or bottom side of the driving unit 1080 and presses the upper side or bottom side of the driving unit 1080 to keep the driving unit 1080 in a tilted state.

[0464] Figure 82 FIG. 1 is a schematic diagram of the structure of the processing box of this embodiment. Figure 82 As shown, the processing cartridge 1 includes a cartridge body O10, a photosensitive drum 20, a developing roller 30, and a power receiving unit 21. In this embodiment, the cartridge body O10 includes a drum frame 12 for supporting the photosensitive drum 20 and a developing frame 11 for supporting the developing roller 30. The drum frame 12 and the developing frame 11 are connected so as to be rotatable relative to each other during operation and can move synchronously together during the installation of the processing cartridge 1. The photosensitive drum 20 is mounted on the drum frame 12, and the developing roller 30 is mounted on the developing frame 11. The photosensitive drum 20 and the developing roller 30 are located at the front side of the processing cartridge 1 along the installation direction, facing each other to perform development and other actions. In this embodiment, the cartridge body O10 also includes an end cap O202, which is mounted on one end of the drum frame 12. The power receiving unit 21 is provided at the first end 1A of the cartridge body O10 and includes a power receiving portion O211 that can engage with the power output portion 1080e to receive a driving force, thereby driving the developing roller 30 and the photosensitive drum 20 to rotate.

[0465] Furthermore, in order to transform the driving unit 1080 from the tilted state of the initial position (in this state, the rotation axis OL1 of the driving unit 1080 is tilted relative to the rotation axis OL2 of the photosensitive drum 20) to the aligned state capable of engaging with the power receiving unit 21 (in this state, the rotation axis of the driving unit 1080 coincides with the rotation axis of the photosensitive drum 20), as shown in FIG. Figure 82 As shown, the process cartridge 1 further includes a pressing member O40, which is disposed at the first end 1A and is used to apply pressure to the drive unit 1080 to align the drive unit 1080. Specifically, the pressing member O40 is fixedly mounted on the end cover O202 to form a fixed connection with the drum frame 12.

[0466] Furthermore, in the direction of the rotation axis OL2 of the photosensitive drum 20, the pressing member O40 is located outside the end of the power receiving portion O211 so as to cooperate with the driving unit 1080 during installation. Figure 83 As shown, on a plane perpendicular to the rotation axis of the photosensitive drum 20 , at least a partial projection of the pressing portion 402 of the cantilever O42 of the pressing member O40 coincides with the projection of the photosensitive drum 20 or falls within the area of ​​the photosensitive drum 20 .

[0467] like Figure 83 As shown, the process cartridge 1 further includes a charging roller O60, which is provided on the cartridge body O10 and is capable of rotating while in contact with the photosensitive drum 20. In other embodiments, the charging member is not limited to such a rotatable contact roller structure. For example, a charging member fixed to the photosensitive drum with a certain distance therebetween may be used. Figure 82 As shown, the pressing member O40 is partially located inside the outer peripheral surface of the photosensitive drum 20, and the pressing member O40 is located above the line connecting the rotation center of the charging roller O60 and the rotation center of the photosensitive drum 20.

[0468] like Figure 84As shown, the pressing member O40 includes a fixing portion O41 and a cantilever arm O42. The fixing portion O41 is connected to the cartridge body O10, and the cantilever arm O42 is connected to the fixing portion O41 and extends toward the photosensitive drum. The fixing portion O41 includes a mounting protrusion O401. In this embodiment, two mounting protrusions O401 are provided, one located above the other. The end cap O202 is provided with a mounting hole corresponding to the mounting protrusion O401. During assembly, the mounting protrusion O401 engages with the mounting hole, securing the pressing member O40 to the end cap O202 or the drum frame 12, thereby enabling the pressing member O40 to move with the movement of the drum frame 12. When the process cartridge is installed in the housing O105 of the electronic imaging device, the cantilever arm O42 passes through the second hole 1090b in the cover 1081 to press the drive unit 1080 of the electronic imaging device. It should be noted that there is no strict limitation on the shape and structure of the fixing portion, as long as the pressing member O40 can be immovable relative to the axis of the photosensitive drum 20 .

[0469] In this embodiment, the cantilever O42 is roughly in the shape of a rectangular parallelepiped, including an upper end surface O42a located on the upper side of the cantilever O42 in the installed state and a lower end surface O42b located on the lower side of the cantilever, and the upper end surface O42a and the lower end surface O42b are arranged to be planes parallel to each other, wherein the lower end surface O42b portion of the free end of the cantilever O42 is configured to press the drive unit 1080 so that the drive unit 1080 is straightened.

[0470] Furthermore, the end of the cantilever arm O42 away from the fixing portion O41 is provided with an arcuate guide surface connecting an upper end surface O42a and a lower end surface O42b. This guide surface is capable of guiding the cantilever arm O42 along the circumferential outer surface of the small-diameter portion 1080f of the drive unit 1080 during the closing of the door cover O102 of the electronic imaging device, thereby preventing interference between the cantilever arm O42 and the drive unit during installation of the process cartridge 1. The two side surfaces of the cantilever arm O42, which are arranged opposite each other along the axis OL2 of the photosensitive drum 20, are configured as flat surfaces, and the maximum distance between the two side surfaces is less than the width of the second hole 1090b (i.e., the width of the hole along the axis OL2 of the photosensitive drum when the process cartridge is in place), thereby preventing the cantilever arm O42 from being unable to pass through the second hole 1090b.

[0471] Continue to refer to Figure 84As shown, due to the distance or space between the input gear portion 1080d of the drive unit 1080 and the front plate 109a, preferably, the thickness B of the cantilever O42 of the pressing member O40 can be set between 0.6mm and 3.5mm. If the thickness of the cantilever O42 is less than 0.6mm, its structure is too thin, and during the installation of the process cartridge 1, the cantilever O42 is easily broken or fractured by the internal structure of the electronic imaging device. If the thickness of the cantilever O42 of the pressing member O40 is too large (greater than 3.5mm), it is also easily limited by the distance between the input gear portion 1080d of the drive unit 1080 and the front plate 109a, and the drive unit 1080 cannot be straightened.

[0472] Reference Figure 83 A force receiving portion O10a is further provided on the rear side of the first end 1A of the box body O10. The force receiving portion O10a is used to receive the force of the box pressing component O1020 when the door cover O102 is closed, so that the processing box 1 is installed in place.

[0473] The following describes in detail how to install the process cartridge into the printer.

[0474] like Figure 85 As shown, first, open the door cover O102. Since the door cover O102 is in the open state, the drive unit 1080 is in the locked state. Align the guide protrusions on both sides of the processing box 1 in the length direction with the guide rails O108 on the first side wall and the second side wall of the accommodating portion O105, and then push the processing box 1 in along the OY1 direction. The pressing piece O40 fixed on the end cover O202 also gradually approaches the drive unit 1080 as the processing box 1 moves until the pressing piece O40 contacts the drive unit 1080.

[0475] like Figure 86 As shown, when the process cartridge 1 is installed in the housing O105 of the electronic imaging device and the door cover O10 is not closed, the cantilever O42 of the pressing member O40 abuts against the upper side of the small-diameter portion 1080f of the drive unit 1080. When viewed from the back of the process cartridge 1, the first end 1A of the process cartridge 1, i.e., the end where the power receiving unit 21 is located, is located higher in the electronic imaging device than the other end 1B of the process cartridge 1 (partially tilted upward). The installation position of the process cartridge in this position is referred to as the first position. At this point, the other end 1B of the process cartridge may be in the installed position.

[0476] like Figure 87 、 Figure 88As shown, the door cover O102 of the electronic imaging device is then closed. As the door cover O102 is closed, the cam O104 releases the lock on the drive unit 1080. The pressing component O1020 inside the door cover O102 pushes the force receiving portion O10a on the rear side of the process cartridge 1, causing the first end 1A of the process cartridge 1 to be subjected to force, thereby moving downward and driving the pressing component O40 downward. At this time, the front end of the pressing component O40 presses the drive unit 1080 downward, causing the rotation axis OL2 of the drive unit 1080 to coincide with or be substantially parallel to the rotation axis OL1 of the power receiving unit 21, thereby allowing the power receiving unit 21 and the drive unit to engage. At this time, the process cartridge 1 is in the second position. That is, after receiving the pressure, the drive unit 1080 moves in a direction closer to the power receiving unit 21. Under the pressure applied by the pressing component O1020 to the left and right sides of the process cartridge 1, the two ends (1A, 1B) of the process cartridge 1 remain substantially horizontal.

[0477] When the process cartridge 1 is installed in place, the drive unit 1080 moves from its initial position to a position where it can engage with the power receiving unit 21, thereby transmitting the driving force from the drive unit 1080 to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate. The installation position of the process cartridge in this position is referred to as the second position. It should be noted that the force applied by the pressing member O40 to the drive unit 1080 to align the drive unit 1080 can be the force applied to the process cartridge 1 by the pressing member O1020 of the door cover O102 when the door cover O102 is closed, or it can be the weight of the process cartridge 1 itself.

[0478] The following describes the specific coordination between the pressing member O40 and the driving unit 1080 during the installation process.

[0479] like Figure 89 As shown, during installation of the process cartridge 1 into the main assembly O101, the pressing member O40 can align the drive unit 1080 through the second hole 1090b. Before the process cartridge is installed, the drive unit 1080 is tilted, with the rotation axis OL1 of the drive unit 1080 forming an angle α with the central axis OL2 of the first hole. When the drive unit 1080 is aligned, the rotation axis OL1 of the drive unit 1080 substantially coincides with the central axis OL0 of the cover member 1081.

[0480] When the process cartridge 1 is installed in the electronic imaging device along the OY1 direction, the lower end surface O42b of the cantilever O42 of the pressing member O40 presses against the small-diameter portion 1080f of the drive unit 1080. Because the abutting surface 1080c of the drive unit 1080 contacts at least one of the first protrusion O82b or the second protrusion O82c of the support side plate O82, the drive unit 1080 tilts in the direction of arrow N, meaning that the drive unit 1080 remains locked. When the door cover O102 is closed, the cylindrical cam O104 releases the lock on the drive unit 1080, and the cartridge pressing member O1020 on the inside of the door cover O102 presses against the force receiving portion O10a of the process cartridge 1, applying force to the first end 1A of the process cartridge 1. Alternatively, both sides of the cartridge body O10 may be simultaneously affected by the force of the cartridge pressing member O1020. The first end 1A of the processing box 1 moves downward and drives the pressing member O40 to move downward. At this time, the lower end surface O42b of the cantilever O42 of the pressing member O40 presses the small diameter portion 1080f of the driving unit 1080. Similarly, the driving unit 1080 is affected by the first protrusion O82b or the second protrusion O82c of the supporting side plate O82, and the driving unit 1080 moves in the opposite direction of the arrow N to be straightened.

[0481] like Figure 90 and 91 As shown, the line connecting the fulcrums at which the first and second protrusions O82b and O82c support the drive unit 1080 is defined as OL3. An axis parallel to OL3 and passing through the center of the rotation axis of the drive unit 1080 is defined as axis OL4. An axis perpendicular to axis OL4 and passing through the center of the rotation axis of the drive unit 1080 is defined as axis OL5. When the process cartridge 1 is in the first and second positions, and when moving from the first position to the second position, the contact point between the pressing member O40 and the drive unit 1080 when applying the pressing force F is always located in the upper half of axis OL4.

[0482] The configuration position of the pressing member O40 can be varied in many ways, such as Figure 92 As shown, when observed along the left and right directions of the mounting portion, in the first position, the angle between the lower end surface O42b of the cantilever O42 of the pressing member O40 and the axis OL5 is β, preferably, 78°≤β≤113°. The position of the pressing member O40 on the processing box meets this condition, and the installation with the electronic imaging device can be achieved. If the angle β is less than 78° or greater than 113°, when the processing box 1 is installed in the electronic imaging device 100, interference will be caused, making it impossible to install the processing box or to align the drive unit 1080.

[0483] The processing box with the above structure can make the contact and engagement process between the power receiving unit and the driving unit smoother, greatly saving the contact and engagement time between the power receiving unit and the driving unit, making the transmission of driving force more stable and improving the working efficiency of the processing box.

[0484] The processing box of this embodiment can also be applied to the electronic imaging device of the aforementioned embodiment.

[0485] In this embodiment, the projection of the cantilever O42 at least partially overlaps with the projection of the photosensitive drum 20. When the process cartridge is installed in the electronic imaging device, the cantilever O42 presses against the small-diameter portion 1080f of the drive unit 1080, thereby aligning the drive unit 1080. That is, the cantilever O42 is closer to the rotation axis of the photosensitive drum, allowing the drive unit 1080 to be better aligned with the power receiving unit. At the same time, because the cantilever portion of the pressing member applies force to the small-diameter portion of the drive unit, the applied force is smaller and more precise, thereby aligning the drive unit from an inclined position to a position nearly coaxial with the photosensitive drum. This allows the process of contacting and engaging the photosensitive drum or developing roller of the process cartridge with the drive unit of the electronic imaging device to be smoother, significantly reducing the time required for the photosensitive drum or developing roller to contact and engage with the drive unit, thereby improving the operating efficiency of the process cartridge.

[0486] Example 16

[0487] Unless otherwise specified, the structure of the processing box in this embodiment is basically the same as the shape, structure, installation and disassembly methods of the processing box in Example 15, and the similarities are not repeated here.

[0488] Figure 93 This is a simplified structural diagram of the process cartridge of this embodiment. In this embodiment, the process cartridge eliminates the power receiving unit located at the first longitudinal end 1A of the photosensitive drum 20 (i.e., the end closest to the drive unit 1080 when installed). Instead, a developing roller gear P301 located at the first longitudinal end of the developing roller 30 (i.e., the end closest to the drive unit 1080 when installed in the electronic imaging device) serves as the power receiving unit. This developing roller gear P301 engages with the gear portion 1080d of the drive unit 1080 to receive driving force. Specifically, the developing roller gear P301 is coaxially arranged with the developing roller 30 and rotates synchronously. The developing roller gear P301 can have a single tooth structure with bevel teeth or a spiral arrangement. Optionally, its upper teeth can be helical to better mesh with the helical teeth of the drive unit 1080. Alternatively, the power receiving unit described in the above embodiment and the developing roller gear P301 described in this embodiment can be used simultaneously to receive driving force from the drive unit 1080.

[0489] Furthermore, the process cartridge also includes a force transmission gear P302 and a photosensitive drum gear P201. The force transmission gear P302 is disposed at a first end or an end opposite the length of the developing roller 30, and the photosensitive drum gear P201 is disposed at a first end or an end opposite the first end of the photosensitive drum 20. The photosensitive drum gear P201 is capable of meshing with the force transmission gear P302, allowing the photosensitive drum 20 to receive driving force via the photosensitive drum gear P201 and the force transmission gear P302. Through this arrangement, the process cartridge can receive driving force from the electronic imaging device and drive rotating components such as the developing roller 30 and the photosensitive drum 20.

[0490] In other embodiments, the developing roller gear P301 may include a helical tooth portion and a spur tooth portion, wherein the helical tooth portion is configured to engage with the gear portion 1080d of the drive unit 1080 to receive driving force, and the spur tooth portion is configured to transmit driving force to the photosensitive drum gear P201. Accordingly, a photosensitive drum gear configured to engage with the spur tooth portion of the developing roller gear 301 may be provided at one end of the photosensitive drum 20, so that the photosensitive drum 20 can receive driving force. Alternatively, the developing roller gear P301 provided at one end of the developing roller 30 may be eliminated, while retaining the power receiving unit provided at the first end of the photosensitive drum 20. The power receiving unit is configured to engage with the drive unit 1080 to receive driving force. Similarly, a photosensitive drum gear may be provided at the first end of the photosensitive drum 20 or at an end opposite to the first end, and a corresponding developing roller gear may be provided at the first end of the developing roller 30 or at another end opposite to the first end, and the developing roller gear may be engaged with the photosensitive drum gear so that the developing roller 30 can receive driving force. Alternatively, in addition to using gears to transmit the driving force between the developing roller 30 and the photosensitive drum 20, a friction wheel, such as a rubber wheel, may also be used. Alternatively, the gear for engaging with the driving unit 1080 and receiving the driving force may be provided on the end of the developing roller, or may be provided separately from the developing roller 30, such as on the end cap, and can engage with the gear portion 1080d of the driving unit 1080 to receive the driving force, and then transmit the driving force to rotating components such as the developing roller 30 and the photosensitive drum 20.

[0491] Embodiment 17

[0492] Unless otherwise specified, the structure of the processing box in this embodiment is basically the same as the shape, structure, installation and disassembly methods of the processing box in Example 15, and the similarities are not repeated here.

[0493] Figure 94A modified version of the pressing member Q40 of this embodiment is shown. In this embodiment, both the upper end surface Q42a and the lower end surface Q42b of the cantilevered arm Q42 of the pressing member Q40 are curved. When the process cartridge is installed in the electronic imaging device, compared to the previous embodiment, the lower end surface Q42b of this embodiment is upwardly concave, while the upper end surface Q42a is upwardly convex. This structural design allows the lower end surface Q42b to better pass over the second side plate 109c of the electronic imaging device during installation, avoiding interference with the second side plate 109c.

[0494] Figure 95 This is another variation of the pressing member Q40 in this embodiment. Both the upper end surface Q42a and the lower end surface Q42b of the cantilever arm Q42 of the pressing member Q40 are curved. When the process cartridge is installed in the accommodating portion Q105, compared to the previous embodiment, the lower end surface Q42b of this embodiment is downwardly convex, while the upper end surface Q42a is downwardly concave. This design, with the curved lower end surface Q42b of the cantilever arm Q42, provides a certain degree of guidance.

[0495] It should be noted that the deformation of the shape structure of the cantilever is not limited to this, and it can also have other deformations, such as the upper end surface is set to convex upward, and the lower end surface is set to convex downward; or, the upper end surface is set to be concave downward, and the lower end surface is set to be concave upward; or the cantilever is set to be cylindrical, conical or prismatic, etc., as long as it can press the drive unit.

[0496] Example 18

[0497] Figure 96 Schematic diagram of the electronic imaging device in this application. Figure 96 As shown, there is an existing electronic imaging device 100, in which the processing box 1 is detachably accommodated. The electronic imaging device 100 includes a door cover R101 that can be opened and closed, a pushing portion R102 that cooperates with the door cover R101, and a driving unit 1080 ( Figure 102 ), the driving unit is the output component of the driving force.

[0498] Figure 97 Schematic diagram of the structure of the processing box in this application. Figure 98 This is a schematic diagram of the structure of the processing box in this application. Figure 97 、 Figure 98As shown, the process cartridge 1 includes a cartridge body R10, a photosensitive drum 20, a developing roller 30, and a power receiving unit 21. The cartridge body R10 contains a developer, and the photosensitive drum 20 and the developing roller 30 are rotatably mounted on the cartridge body R10. The power receiving unit 21 is disposed at one end of the cartridge body R10 and connected to the photosensitive drum 20. The power receiving unit 21 includes a power receiving portion R21a for receiving a driving force output by a driving unit 1080 in the electronic imaging device, thereby rotating the photosensitive drum 20.

[0499] Furthermore, the process cartridge 1 further includes a pressing member R40. During the engagement between the power receiving unit 21 and the drive unit 1080, the pressing member R40 can apply pressure to the drive unit to align the drive unit. Specifically, the cartridge body R10 includes a bracket R11. The pressing member R40 is fixedly mounted on the bracket R11, and at least a portion of the pressing member R40 is located within the outer peripheral surface of the photosensitive drum 20. During the engagement between the power receiving unit and the drive unit of the electronic imaging device, the pressing member R40 can contact the drive unit 1080 of the electronic imaging device to align the drive unit.

[0500] Specifically, such as Figure 98 、 Figure 99 As shown, the bracket R11 includes a slide groove R111, a mounting portion R112, a recess and a protrusion R11a. The protrusion R11a is arranged in the slide groove R111 for fixing one end of the elastic component R511, and the recess R113 is used to install the pressing member R40.

[0501] like Figure 100 As shown, the process cartridge 1 further includes a control mechanism R50, which cooperates with the power receiving unit 21 to control the extension and retraction of the power receiving unit 21, i.e., to control the axial movement of the power receiving unit 21 along the photosensitive drum 20. Furthermore, the power receiving unit 21 is located in the mounting portion R112. The control mechanism R50 includes a push rod R51, an elastic component R511, a linkage member R52, and a restriction member R53. The push rod R51 is movably mounted in the chute R111. The linkage member R52 and the restriction member R53 cooperate with each other and are sleeved on the power receiving unit 21. The linkage member R52 is movably connected to the push rod R51. The elastic component R511 is disposed on the push rod R51, with one end connected to the protrusion R11a, and is used to reset the push rod R51. In this embodiment, the elastic component R511 is a spring. In other embodiments, the elastic component R511 can also be made of other elastic materials, such as rubber, silicone, sponge, etc.

[0502] Specifically, the push rod R51 includes a first protrusion R51a and a second protrusion R51b, wherein the second protrusion R51b is used to connect to the other end of the elastic component R511. The linkage member R52 includes a connecting portion R52a and a first protrusion R52b, and the connecting portion R52a is movably connected to the first protrusion R51a of the push rod R51. The limiting member R53 includes a second protrusion R53a and a flat portion R53b. As the process cartridge 1 is in different states, the linkage member R52 can move between the second protrusion R53a and the flat portion R53b of the limiting member R53. The specific operation will be detailed later.

[0503] Figure 101a This is an exploded view of the installation of the power receiving unit and the photosensitive drum. Figure 101a As shown, the power receiving unit 21 includes a power receiving portion R21a, a power output portion R21b, an intermediate member R23, and an elastic member R22. The intermediate member R23 is disposed at one end of the photosensitive drum 20. The power receiving portion R21a is movably mounted on the intermediate member R23 and extends through the linkage member R52 and the limiting member R53. It is configured to engage with the drive unit of the electronic imaging device to receive the driving force outputted from the electronic imaging device. The power output portion R21b is connected to the power receiving portion R21a and is configured to input the driving force to the photosensitive drum 20, enabling the photosensitive drum 20 to rotate with the rotation of the power receiving unit 21. The elastic member R22 is disposed between the power receiving unit 21 and the intermediate member R23. One end of the elastic member R22 is connected to the intermediate member R23, and the other end is connected to the power receiving unit 21. In this embodiment, the elastic member R22 is a spring. In other embodiments, the elastic member R22 can also be made of other elastic materials, such as rubber, silicone, sponge, etc.

[0504] Figure 101b This is a partial view of the photosensitive drum and the developing roller in this application. Figure 101b As shown, the processing box also includes an intermediate gear R301 and a photosensitive drum gear R201. The intermediate gear R301 is arranged at the end of the developing roller 30, and the photosensitive drum gear R201 is arranged at the end of the photosensitive drum 20. The photosensitive drum gear R201 is engaged with the intermediate gear R301, so that the developing roller 30 can receive the driving force through the intermediate gear R301 and the photosensitive drum gear R201, thereby causing the developing roller 30 to rotate.

[0505] Figure 102 This is a schematic diagram of the drive unit structure of the electronic imaging device in this application. Drive unit 1080 includes a gear portion 1080d, a small-diameter portion 1080f, and a coupling portion 1080e. During engagement between the power receiving unit and the drive unit of the electronic imaging device, pressing member R40 presses against small-diameter portion 1080f of drive unit 1080, thereby aligning drive unit 1080. The detailed alignment process is described below.

[0506] Figure 103 FIG is a partial schematic diagram of the power receiving unit in the present application in a retracted state. Figure 103 As shown, when the processing box 1 is installed in the electronic imaging device (not shown), and the door cover R101 of the electronic imaging device has not yet been closed, the pressing member R40 presses the small diameter portion 1080f of the drive unit 1080, but at this time, the drive unit 1080 of the electronic imaging device 100 is still in a tilted state. The elastic component R511 in the push rod R51 of the control mechanism R50 is in the initial state (no deformation occurs), and the first protrusion R52b of the linkage member R52 contacts the second protrusion R53a of the limiting member R53, causing the elastic member R22 disposed between the power receiving unit 21 and the intermediate member R23 to be compressed, and the compression amount is referred to as the first compression amount. At this time, the plane of the power receiving portion R21a of the power receiving unit 21 is located inside the plane of the linkage member R52 or is flush with the plane of the linkage member R52, or it can be in an extended state, which does not cause interference during installation. In this state, the power receiving unit 21 is not combined with the drive unit 1080.

[0507] Figure 104 This is a partial schematic diagram of the power receiving unit in the present application in an extended state. When the door cover R101 of the electronic imaging device is fully closed, the pressing member R40 has completed its alignment of the drive unit 1080, and the drive unit 1080 is in an aligned state. At this point, the door cover R101 is fully closed, and the push rod R51 of the control mechanism R50, acting upon the pressing portion R102, compresses the elastic member R511, thereby driving the linkage member R52 to rotate. The first protrusion R52b of the linkage member R52 shifts from contacting the second protrusion R53a of the restricting member R53 to contacting the flat surface R53b. This compresses the elastic member R22 disposed between the power receiving unit 21 and the intermediate member R23. This compression is referred to as a second compression. Because the linkage member R52 has axial movement, the first compression is greater than the second compression. Therefore, in this state, the power receiving unit 21 is in an extended state, meaning that the plane of the power receiving portion R21a of the power receiving unit 21 protrudes beyond the plane of the linkage member R52. Since the driving unit 1080 has been straightened at this time, the power receiving portion R21a of the power receiving unit 21 is connected with the engaging portion 1080e of the driving unit 1080, completing the engagement.

[0508] Example 19

[0509] This embodiment discloses a process cartridge comprising a cartridge body, a photosensitive drum, a developing roller, a power receiving unit, and a pressing member. The photosensitive drum and developing roller are rotatably mounted on the cartridge body, and the power receiving unit is connected to the photosensitive drum. The pressing member is disposed within the cartridge body and is located at the same end of the cartridge body as the power receiving unit. The pressing member is capable of displacement relative to the cartridge body to align the position of a drive unit of an electronic imaging device, enabling engagement between the drive unit and the power receiving unit to transmit the output driving force of the drive unit to the photosensitive drum and developing roller.

[0510] In this embodiment, the power receiving unit is connected to the photosensitive drum. It can be understood that in other embodiments, the power receiving unit can also be connected to the developing roller, or two power receiving units can be provided, one of which is connected to the photosensitive drum and the other is connected to the developing roller.

[0511] like Figure 105 and Figure 106 As shown, the pressing member S40 is a retractable component. Specifically, the pressing member S40 is detachably connected to the process cartridge 1. The process cartridge further includes an elastic member S60 (such as a spring, a magnet, an elastic sponge, etc.). The pressing member S40 is connected to the end of the cartridge body via the elastic member S60. Under the action of the elastic member S60, the pressing member S40 can move relative to the cartridge body in a direction parallel or substantially parallel to the axial direction of the photosensitive drum to press the drive unit 1080. The direction substantially parallel to the axial direction of the photosensitive drum can be a direction forming a certain angle with the axial direction of the photosensitive drum, and the angle can be within ±5°.

[0512] Furthermore, the pressing member S40 includes a rod body coaxially arranged with the photosensitive drum 20 and a protrusion S41 formed by bending and extending from one end of the rod body. The rod body is connected to the box body through an elastic member S60. The protrusion S41 is arranged close to the power receiving unit 21 and is used to press down the driving unit of the electronic imaging device so that the driving unit and the power receiving unit 21 are basically coaxially engaged to transmit power.

[0513] When the elastic member S60 is in a compressed state, the pressing member S40 can move along the length direction of the process cartridge 1 or the axial direction of the photosensitive drum 20, so that the pressing member S40 is away from the driving unit 1080. When the elastic member S60 is in a relaxed state, the pressing member S40 can move along the length direction of the process cartridge 1 or the axial direction of the photosensitive drum 20, so that the pressing member S40 is close to the driving unit 1080, and drives the driving unit 1080 to press downward.

[0514] During the installation process of the electronic imaging device or after the processing box 1 of this embodiment is installed in place, the pressing member S40 can move along the length direction of the processing box 1 or the axial direction of the photosensitive drum 20 and press the driving unit, thereby adjusting the position of the driving unit 1080 of the electronic imaging device, making the driving unit 1080 coaxial or basically coaxial with the power receiving unit 21, and then making the driving unit 1080 engage with the power receiving unit 21 to transmit power, and transmit the driving force output by the driving unit 1080 to the photosensitive drum and the developing roller.

[0515] Example 20

[0516] This embodiment provides another processing box, and the unexplained parts are the same as those in the aforementioned embodiments and will not be described again for the sake of simplicity.

[0517] The difference between this embodiment and the above embodiments is that the pressing member in the processing box of this embodiment is sleeved on the outside of the power receiving unit and rotates coaxially with the photosensitive drum.

[0518] Specifically, such as Figure 107 and Figure 108 As shown, the process cartridge further includes a telescopic mechanism T70 and a pressing member T40, the power receiving unit 21 is connected to one end of the photosensitive drum 20, the telescopic mechanism T70 is disposed inside the photosensitive drum 20, and the power receiving unit 21 is connected to the photosensitive drum 20 via the telescopic mechanism T70, so that the power receiving unit 21 can move in the axial direction of the photosensitive drum 20. Optionally, the telescopic mechanism T70 is an elastic member, which can be a spring, a magnet, an elastic sponge, or other components with elastic force, which are not limited here.

[0519] In this embodiment, the elastic member is a spring. A groove 20 a is provided at the end of the photosensitive drum 20 , and the spring is received in the groove 20 a at the end of the photosensitive drum 20 .

[0520] The pressing member T40 is sleeved on the outer side of the power receiving unit 21 away from the retractable mechanism T70. The pressing member T40 is rotatable coaxially with the photosensitive drum 20, allowing the pressing member T40 to move axially with the power receiving unit 21. In this embodiment, the pressing member T40 is a rotatable sleeve, which may be hollow cylindrical. The power receiving unit 21 is accommodated within the sleeve and is movable along the sleeve.

[0521] Specifically, one end of the telescopic mechanism T70 (elastic member) abuts against the inner wall of the groove 20 a , and the other end of the telescopic mechanism T70 (elastic member) abuts against the power receiving unit 21 .

[0522] When the process cartridge is not installed in the electronic imaging device, the power receiving unit 21 can use the friction between the power receiving unit 21 and the pressing member T40 to resist the elastic force of the telescopic mechanism T70 and retreat to be accommodated in the pressing member T40. When the process cartridge is installed in the electronic imaging device, the drive unit 1080 is in a tilted state, that is, the axis of the drive unit 1080 is not parallel to the axis of the photosensitive drum 20. Since the pressing member T40 is sleeved on the outside of the power receiving unit 21, the pressing member T40 and the drive unit 1080 form a structural interference. At this time, the drive unit 1080 begins to rotate and drives the pressing member T40 to rotate. During the rotation of the pressing member T40, the centrifugal force generated by the pressing member T40 causes the driving unit 1080 to gradually move from its original tilted state to a position where the axis of the driving unit 1080 coincides with the axis of the photosensitive drum 20. At this time, the driving unit 1080 is coaxial with the photosensitive drum 20. After the pressing member T40 rotates centrifugally, the friction between the power receiving unit 21 and the pressing member T40 is reduced. The elastic force of the telescopic mechanism T70 is used to drive the power receiving unit 21 to move along the axial direction of the photosensitive drum 20 toward the direction close to the driving unit 1080. Through this movement of the power receiving unit 21, the power receiving unit 21 is extended from the pressing member T40, thereby successfully engaging with the driving unit 1080, thereby realizing power transmission between the driving unit 1080 and the photosensitive drum 20.

[0523] Example 21

[0524] like Figure 109 As shown, the power receiving unit U22 and the pressing member U23 are respectively disposed at one end of the photosensitive drum 20. In this embodiment, there are two power receiving units U22, or three, with no limitation on their number. Both the power receiving unit U22 and the pressing member U23 are capable of moving relative to the housing in the axial direction of the photosensitive drum 20. The pressing member U23 is also capable of moving relative to the power receiving unit U22 within a first planar region and in a direction perpendicular to the axial direction of the photosensitive drum 20. The pressing member U23 is used to adjust the position of the drive unit 1080, and the power receiving unit U22 is used to engage with the drive unit of the electronic imaging device. The projection of the first planar region on a plane perpendicular to the axial direction of the photosensitive drum at least partially overlaps with the projection of the photosensitive drum.

[0525] Furthermore, the processing cartridge also includes a first elastic member U211 and a second elastic member U231. The power receiving unit U22 and the pressing member U23 are connected to the photosensitive drum 20 via the first elastic member U211. The first elastic member U211 imparts to the power receiving unit U22 and the pressing member U23 the ability to translate along the axial direction of the photosensitive drum 20. The pressing member U23 is connected to the power receiving unit U22 via the second elastic member U231. The second elastic member U231 imparts to the pressing member U23 the ability to translate in a direction perpendicular to the axial direction of the photosensitive drum 20. Specifically, the drive gear is disposed on the photosensitive drum 20. One end of the first elastic member U211 is disposed on the inner wall U2100 of the drive gear, and the other end is directly or indirectly attached to an inner side surface U210 of the power receiving unit U22 and the pressing member U23 that faces the inner wall of the drive gear. When the first elastic member U211 is deformed by force (e.g., compressed), the power receiving unit U22 and the pressing member U23 can translate along the axial direction of the photosensitive drum toward the direction of extending into the processing cartridge. When the first elastic member U211 releases its elastic force (e.g., stretches), the power receiving unit U22 and the pressing member U23 can translate along the axial direction of the photosensitive axis toward the direction of extending out of the processing cartridge. Of course, conventional structures such as a restricting structure can also be provided to prevent the power receiving unit U22 and the pressing member U23 from slipping out of the processing cartridge, thereby enabling the power receiving unit U22 and the pressing member U23 to translate along the axial direction of the photosensitive drum. In this embodiment, the initial state of the first elastic member U211 is such that the power receiving unit U22 and the pressing member U23 are in a compressed state extending into the processing cartridge. The second elastic member U231 only acts on the pressing member U23. The second elastic member U231 gives the pressing member U23 the ability to expand and contract in a direction perpendicular to the axial direction of the photosensitive drum, so that the pressing member U23 can produce displacement in a direction perpendicular to the axial direction of the photosensitive drum, and is not limited to moving only perpendicular to the axial direction. The second elastic member U231 can be set in a manner similar to the first elastic member U211, one end of which can be set on the inner wall of the driving gear or on the power receiving unit U22. In this embodiment, it is set on a wall U220 inside the power receiving unit U22, and the other end is directly or indirectly set on the pressing member U23. The initial state of the second elastic member U231 is a state in which the pressing member U23 is compressed in a direction perpendicular to the axial direction of the photosensitive drum. When the second elastic member U231 releases the elastic force (such as stretching), the pressing member U23 can translate in a direction perpendicular to the axial direction of the photosensitive drum toward a direction away from the power receiving unit U22. When the second elastic member U231 is deformed by force (such as compression), the pressing member U23 can translate in a direction perpendicular to the axial direction of the photosensitive drum toward a direction close to the power receiving unit U22. For setting and maintaining the initial state of the second elastic member U231, a limiting portion U2311 is preferably provided. The limiting portion U2311 is a block-shaped or strip-shaped component fixedly provided on the box body and is used to limit the position of the pressing member U23.In this embodiment, the restriction method is that the limiting portion U2311 of the strip-shaped component "supports" the pressing member U23, that is, the second elastic member U231 compresses and makes the pressing member U23 abut against the limiting portion U2311, and the pressing member U23 and / or the second elastic member U231 can move relative to the limiting portion U2311, and the movement method can be that the pressing member U23 and / or the second elastic member U231 slides on the limiting portion U2311.

[0526] Furthermore, the processing box also includes a control lever U810 and a rotatable buckle U820. The control lever U810 is used to receive an external force such as that caused by the closing action of the door cover 13 of the electronic imaging device, and then control the above-mentioned power receiving unit U21 to extend the processing box along the axial direction of the photosensitive drum. The buckle U820 is set on the box body and can rotate around the rotation axis U821. The buckle U820 can prevent the power receiving unit U21 from moving in the axial direction of the photosensitive drum. Figure 110 As shown, when the process cartridge is installed in the electronic imaging device, the drive unit 1080 is in a tilted state, that is, the axis of the drive unit 1080 is not parallel to the axis of the photosensitive drum 20. When the door cover 13 is closed so that the control lever U810 controls the power receiving unit 21 to extend the process cartridge along the axial direction of the photosensitive drum, as shown in FIG. Figures 110 to 111 The action change process is as follows: first, the buckle U820 can block the power receiving unit U22 from extending, and the pressing member U23 can be extended, which does not affect the extension of the first elastic member U211. Alternatively, the first elastic member U211 can be set into two parts to control the power receiving unit U22 and the pressing member U23 respectively. Then, when the pressing member U23 and / or the second elastic member U231 are moving in the direction away from the power receiving unit U22, relative displacement will also occur with the fixed limiting portion U2311. Figure 111 Move to Figure 112 In the state of , it can be released by the limiting part U2311. In this embodiment, the release method is that the pressing member U23 and / or the second elastic member U231 slides out of the limiting part U2311 during the movement, for example, it can leave the limiting part U2311 and not contact it, so as to break away from the restriction of the limiting part U2311. During this process, the pressing member U23 extends outward to be able to abut on the driving unit 1080, and the pressing member U23 forms a certain pressure on the driving unit 1080, guiding the driving unit 1080 to gradually rotate and straighten until it forms a Figure 112 In the state shown, the pressing member U23 is fully extended outward and abuts against the driving unit 1080, so that the driving unit 1080 moves from the tilted state to a position where its axis is substantially parallel or coaxial with the axis of the photosensitive drum 20. At this time, the power receiving unit U21 is not fully engaged with the driving unit 1080. Figure 113As shown, when the buckle U820 of this embodiment is triggered or rotates automatically, its blocking effect on the power receiving unit U22 is released, so that the power receiving unit U22 extends out of the processing box under the stretching action of the first elastic member U211, thereby smoothly contacting and engaging with the aligned driving unit 1080. This state completes the complete engagement of the power receiving unit 21 and the driving unit 1080.

[0527] Furthermore, a slope U2312 may be provided on the limiting portion U2311 (such as a free end) to assist the pressing member U23 in returning in the axial direction of the photosensitive drum and in a direction perpendicular to the axial direction of the photosensitive drum.

[0528] Furthermore, in Figures 110 to 111 In the process of action changes, this embodiment may also not rely on the snap fastener U820 to block the movement of the power receiving unit U22 in the axial direction of the photosensitive drum, but instead uses the drive unit 1080 or the drive unit protective cover 1081 located outside the drive unit 1080 to play a blocking role, that is, the power receiving unit U22 is directly blocked by the end of the drive unit 1080 or the drive unit protective cover 1081, and after being straightened, it further extends outward to complete the engagement, which can also achieve the purpose of this embodiment.

[0529] Example 22

[0530] like Figure 114 As shown, the process cartridge 1 further includes a control mechanism V30. The control mechanism V30 can be fixed to the process cartridge 1 by being disposed on a guide rail (not shown) on the end cover. The control mechanism V30 can move along the guide rail in a direction perpendicular to the length of the process cartridge. Specifically, the control mechanism V30 has a first end V31 and a second end V32, wherein the end of the second end V32 is further provided with an inclined surface V322. Optionally, the control mechanism in this embodiment can be a push rod.

[0531] Figure 115 This is a schematic structural diagram of the force receiving part of the power receiving unit in Example 22. Figure 116 This is a schematic structural diagram of the force transmission part of the power receiving unit in Example 22. Figure 117 FIG2 is a schematic structural diagram of the flange of the power receiving unit in Example 22. Figure 115 and Figure 116 As shown, the power receiving unit 21 includes a force receiving portion V22 , a force transmitting portion V23 and a flange V24 .

[0532] Specifically, the force receiving portion V22 includes a convex portion V221 for receiving driving force from the electronic imaging device, a protrusion V222, and two first fixing posts V223 disposed on either side of the protrusion V222. The force transmitting portion V23 includes a connecting portion V232, a groove V231 disposed at one end of the connecting portion V232 for engaging with the force receiving portion V22, a limiting surface V234 disposed at the other end of the connecting portion V232, and a notch V235. Second fixing posts V233 are disposed on either side of the groove V231. Furthermore, the flange V24 is a circular component, and the flange V24 is provided with a receiving portion V242, wherein a positioning column V243 and an elastically deformable swinging member V244 are provided in the receiving portion V242. In addition, an abutting portion V241 is extended along the outer circumference of the flange V24, and an abutting surface V2411 is provided at one end of the abutting portion V241. Specifically, the abutting surface V2411 is a slope.

[0533] Figure 118 FIG2 is a schematic diagram of the structure of the support member in Example 22. Figure 118 As shown, the carrier V50 includes a carrier portion V51 , a through hole V52 , and a plurality of first protrusions V53 arranged circumferentially outside the carrier portion V51 .

[0534] Specifically, such as Figure 119 As shown, the assembly relationship between the power receiving unit 21 and the carrier V50 is: the force receiving portion V22 is installed on the groove V231 of the force transmitting portion V23 through the protrusion V222, thereby being fixed to the force transmitting portion V23 and allowing the force receiving portion V22 to move along the LL direction ( Figure 119The first elastic member V61 connects the two first fixing posts V223 of the force receiving portion V22 and the two second fixing posts V233 of the force transmitting portion V24, thereby enabling the force receiving portion V22 to return to its original position when no longer receiving driving force. When the first elastic member V61 is in its natural state, the force receiving portion V22 extends relative to the force transmitting portion V23 toward the exterior of the process cartridge 1. The force transmission part V23 is arranged in the accommodating part V242 of the flange V24. At this time, the limiting surface V234 of the force transmission part V23 abuts against the accommodating part V242, and the positioning column V243 in the flange V24 is connected to the connecting part V232 of the force transmission part V23 through the second elastic part V63, so that the force receiving part V22 movably connected to the force transmission part V23 can be biased at a predetermined phase, and the swinging part V244 is used to contact the second elastic part V63 during the process of driving the second elastic part V63 to move when the force transmission part V23 receives power from the force receiving part V22 and rotates to prevent it from being unable to reset. At this time, the various parts of the power receiving unit 21 can be installed in sequence and then installed together in the carrier V50. The force transmission part V23 passes through the through hole V52 of the carrier V50, so that the power receiving unit 21 is fixed to the carrier V50. At the same time, the third elastic part V64 is sleeved on one end of the force transmission part V23 passing through the through hole V52. One end of the third elastic part V64 abuts against the bearing part V53 of the carrier V50, and the other end abuts against the clutch part V80, wherein the clutch part V80 is connected to the force transmission part V23 through an axle pin (not shown in the figure) through the slot V235, and a plurality of second protrusions V81 arranged in a circumferential arrangement are provided on the end of the clutch part V80 facing the carrier V50. The above-mentioned various parts can be assembled as a whole in the photosensitive drum 20 after cooperating with each other, see Figure 119 .

[0535] In this embodiment, the pressing member is integrated into the power receiving portion, and the power receiving portion V22 is movable in a first plane region and along a first direction for engaging with the drive unit 1080 and adjusting the position of the drive unit. In this embodiment, the projection of the first plane region on a plane perpendicular to the axial direction of the photosensitive drum at least partially overlaps with the projection of the photosensitive drum, and the first direction intersects with the axial direction of the photosensitive drum and is not perpendicular to the axial direction of the photosensitive drum, i.e. Figure 119 LL direction in .

[0536] The following describes the process of engagement and disengagement between the power receiving unit of the process cartridge and the driving unit of the electronic imaging device.

[0537] like Figure 119 and Figure 120As shown, when the processing box 1 has not been installed in the electronic imaging device or has not received external force after being installed in the electronic imaging device, the power receiving unit 21 is in an initial state, that is, the force receiving part V22 extends relative to the flange V24 along the axial direction of the photosensitive drum 20 under the action of the first elastic member V61.

[0538] like Figure 121 As shown, when the process cartridge 1 is installed in the electronic imaging device and the door cover is closed, the control mechanism V30 on the process cartridge is subjected to an external force and moves along the X direction. At this time, the inclined surface V322 on the second end V32 of the control mechanism V30 moves to a position in contact with the abutting surface V2411 of the flange V24. As the control mechanism V30 continues to move, the inclined surface V322 successfully abuts against the abutting surface V2411 and applies a force in the X direction to the flange V24. As the limiting surface V234 of the force transmitting portion V23 and the flange V24 are The accommodating portion V242 of the flange V24 abuts against the accommodating portion V242 of the flange V24, and the clutch V80 is movably connected with the force transmitting portion V23. Therefore, after the flange V24 is subjected to the force, it moves along the Y4 direction (i.e., toward the direction of the driving unit 1080) with the force transmitting portion V23 together with the force receiving portion V22 and the clutch V80. At this time, the force receiving portion V22 moves along the Y4 direction to a position abutting against the driving unit 1080 in the electronic imaging device, that is, the protrusion V221 of the force receiving portion V22 is clamped to the electronic imaging device. In the driving unit 1080 in the device, the driving unit 1080 in the electronic imaging device is still in a tilted state at this time. At the same time, as the control mechanism V30 continues to move along the X direction, the flange V24 drives the force transmission part V23 to move along the Y4 direction. However, at this moment, the force receiving part V22 is already connected to the driving unit 1080 and can no longer continue to move in the Y4 direction with the force transmission part V23. Instead, it moves relative to the force transmission part V23 through the groove V231 of the force transmission part V23, that is, it moves relative to the flange V24. At the same time, the force receiving part V22 moves horizontally in the driving unit 1080, and the translation is a radial movement relative to the driving unit 1080. When the protrusion V221 of the force receiving part V22 abuts against the side of the inner recess of the driving unit 1080, it drives the driving unit 1080 to move, so that the driving unit 1080 moves from the initial tilted state to a position where its axis is basically parallel or coaxial with the axis of the photosensitive drum 20.

[0539] like Figure 122 and Figure 123As shown, after the control mechanism V30 moves into position, the flange V24 abuts against the drive unit protective cover 1081 and no longer moves. At this time, the clutch member V80 also overcomes the elastic force of the third elastic member V64 and moves to a position in contact with the carrier V50. The second protrusion V81 of the clutch member V80 successfully engages with the first protrusion V53 of the carrier V50. At this time, the force receiving part V22 also drives the drive unit 1080 to move to a position coaxial with the photosensitive drum 20, thereby realizing the transmission of driving force between the drive unit 1080 and the photosensitive drum.

[0540] When the door cover of the electronic imaging device is opened, the external force acting on the control mechanism V30 disappears, and the flange V24 retracts in the direction opposite to the Y4 direction and moves with the power transmission part V23. At this time, the clutch V80 also moves in the direction opposite to the Y4 direction. The third elastic part V64 resets after losing the force of the clutch V80, and the force receiving part V22 also disengages from the drive unit 1080. Finally, the power receiving unit 21 returns to its initial state, so that the processing box can be successfully removed from the electronic imaging device.

[0541] Example 23

[0542] This embodiment provides another control mechanism, which is a further improvement based on the embodiment 22. The unexplained parts are the same as those in the aforementioned embodiments and will not be described again for the sake of simplicity.

[0543] like Figure 124 As shown, the control mechanism W30 is movably disposed on the end of the cartridge body. Specifically, the control mechanism W30 includes a first end W31, a second end W32, and an axial hole W33, wherein a sloped surface W322 is provided at the end of the second end W32. Optionally, the control mechanism W30 can be movably connected to an end cover (not shown) via the axial hole W33 and thus fixed to the cartridge body, thereby allowing the control mechanism W30 to swing in a plane perpendicular to the axial direction of the photosensitive drum 20.

[0544] Furthermore, the control mechanism on the process cartridge can also be a power source. When the control mechanism is a power source, it can receive instructions by closing the door cover of the electronic imaging device, thereby operating the flange and the force receiving and force transmitting parts to extend toward the drive unit, and can control the power receiving unit 21 to stop after extending a certain distance. Alternatively, the power source can be a motor, light power, etc.

[0545] The process of the power receiving unit contacting and engaging with the driving unit of the electronic imaging device: when the processing box has not been installed in the electronic imaging device or has not received external force after being installed in the electronic imaging device, the power receiving unit 21 is in an initial state, that is, the force receiving part V22 extends relative to the flange V24 along the axial direction of the photosensitive drum 20 under the action of the first elastic member V61.

[0546] When the process cartridge 1 is installed in the electronic imaging device and the door cover is closed, the control mechanism W30 on the process cartridge is subjected to an external force and swings on a plane perpendicular to the axial direction of the photosensitive drum 20. At this time, the inclined surface W322 on the second end W32 of the control mechanism W30 moves to a position in contact with the abutment surface V2411 of the flange V24. As the control mechanism W30 continues to move, the inclined surface W322 successfully abuts against the abutment surface V2411 and applies a force in the X direction to the flange V24. Due to the force transmission part V23 The limiting surface V234 of the flange V24 abuts against the accommodating portion V242 of the flange V24, and the clutch V80 is movably connected to the force transmitting portion V23. Therefore, after the flange V24 is subjected to the force, it moves along the Y4 direction (i.e., toward the direction of the driving unit 1080) with the force transmitting portion V23 together with the force receiving portion V22 and the clutch V80. At this time, the force receiving portion V22 moves along the Y4 direction to a position abutting against the driving unit 1080 in the electronic imaging device, i.e., the convex block V22 of the force receiving portion V22 1 is clipped into the drive unit 1080 in the electronic imaging device. At this time, the drive unit 1080 in the electronic imaging device is still in a tilted state. At the same time, as the control mechanism W30 continues to move, the flange V24 drives the force transmitting part V23 to move along the Y4 direction. However, at this moment, the force receiving part V22 is already connected to the drive unit 1080 and can no longer continue to move in the Y4 direction with the force transmitting part V23. Instead, it moves relative to the force transmitting part V23 through the groove V231 of the force transmitting part V23, that is, it moves relative to the flange V24. At the same time, the force receiving part V22 moves horizontally in the drive unit 1080, and the translation is a radial movement relative to the drive unit 1080. When the protrusion V221 of the force receiving part V22 abuts against the side of the inner recess of the drive unit 1080, it drives the drive unit 1080 to move, so that the drive unit 1080 moves from the initial tilted state to a position where its axis is basically parallel or coaxial with the axis of the photosensitive drum 20.

[0547] As the control mechanism W30 moves into position, the flange V24 abuts the position of the drive unit protective cover 1081 and no longer moves. At this time, the clutch member V80 also overcomes the elastic force of the third elastic member V64 and moves to the position in contact with the carrier V50. The second protrusion V81 of the clutch member V80 successfully engages with the first protrusion V53 of the carrier V50. At this time, the force receiving part V22 also drives the drive unit 1080 to move to a position coaxial with the photosensitive drum 20, thereby realizing the transmission of driving force between the drive unit 1080 and the photosensitive drum.

[0548] When the door cover of the electronic imaging device is opened, the external force acting on the control mechanism W30 disappears. At this time, the flange V24 retracts in the direction opposite to the Y4 direction and moves with the power transmission part V23. At this time, the clutch V80 also moves in the direction opposite to the Y4 direction. The third elastic part V64 resets after losing the force of the clutch V80, and the force receiving part V22 also disengages from the drive unit 1080. Finally, the power receiving unit 21 returns to its initial state, so that the processing box can be successfully removed from the electronic imaging device.

[0549] Example 24

[0550] Figure 125 Schematic diagram of the electronic imaging device in Example 24. As shown in the figure, there is an electronic imaging device 100 in which the processing cartridge 1 is detachably accommodated. The electronic imaging device 100 includes a door cover 101 that can be opened and closed, a pushing portion 102 that cooperates with the door cover 101, and a driving unit 1080 ( Figure 131 ), which is the output component of the driving force.

[0551] Figure 126 FIG. 2 is a schematic diagram of the structure of the processing box in Example 24. Figure 126 As shown, the process cartridge 1 includes a cartridge body X50, a photosensitive drum 20, a developing roller 30, a bracket X51, a pressing member X40, and a power receiving unit. The photosensitive drum 20 and the developing roller 30 are rotatably mounted on the cartridge body X50, and the bracket X51 is disposed at the end of the cartridge body X50. The pressing member X40 is capable of aligning the driving unit 1080. The power receiving unit is configured to engage with the driving unit 1080 to receive the driving force output by the driving unit in the electronic imaging device. The cartridge body X50 contains developer.

[0552] Figure 127 Schematic diagram of the support of the processing box in Example 24. Figure 127 As shown, the bracket X51 is provided on one side of the box body X50 for mounting the pressing member X40, and the bracket X51 includes a slide groove X51a, a mounting portion X51b, and a connecting hole X51c. The push rod X41 is mounted in the slide groove X51a, and the telescopic rod 43 is sleeved on the mounting portion X51b.

[0553] Figure 128 FIG. 2 is a schematic diagram of the structure of the pressing member in Example 24. Figure 128As shown, the pressing member includes a push rod X41, a connecting member X42, a telescopic member X43, a first elastic member X41a, and a second elastic member X43a. The telescopic member X43 is movably mounted on a bracket X51 and is capable of axial movement along the photosensitive drum. The push rod X41 is movably mounted on the bracket X51 and connected to the telescopic member X43 via the connecting member X42. The push rod X41 can drive the telescopic member X43 to move axially along the photosensitive drum. The first elastic member X41a is sleeved over the push rod X41 and is used to reset the push rod X41. One end of the second elastic member X43a is connected to the telescopic member X43, and the other end of the second elastic member X43a is connected to the inner wall of the mounting portion X51b, which is used to reset the telescopic member X43. The push rod X41 includes a first connecting portion X41b, which is connected to one end of the connecting member X42. The telescopic member X43 includes a second connecting portion X43b, which is used to connect to the other end of the connecting member X42. It should be noted that in this application, the first elastic member X41a and the second elastic member X43a are springs, but may also be other elastically deformable components. The connecting member X42 may be made of a flexible and deformable material. In this embodiment, the use of a dual-spring structure can make the retractable member X43 more effective in resetting, reducing the possibility of interference when removing the process cartridge.

[0554] Figure 129 This is a schematic diagram of the structure in which the pressing member is installed on the bracket in Example 24. Figure 129 As shown, the push rod X41 is mounted in the slide slot X51a of the bracket X51, the telescopic member X43 is sleeved within the bracket's mounting portion X51b, and one end of the connecting member X42 is mounted on the first connecting portion X41b of the push rod X41. The other end is connected to the second connecting portion X43b of the telescopic member X43 through the connecting hole X51c of the bracket X51. Furthermore, the mounting portion X51b has a fixed portion for mounting one end of the second spring X43a and a notch for the second connecting portion X43b to extend. The second connecting portion X43b can slide in the notch while the telescopic member X43 is aligning the drive unit.

[0555] Figure 130 This is a partial view of the swing rod in Example 24. Specifically, Figure 130 As shown, the power receiving unit 21 is disposed at the end of the developing roller 30 and is used to engage with the drive unit 1080 of the electronic imaging device to receive the driving force output by the drive unit, thereby causing the developing roller 30 to rotate. Furthermore, an intermediate gear X32 is provided on the developing roller 30, and a photosensitive drum gear X211 is provided at the end of the photosensitive drum 20. The photosensitive drum gear X211 engages with the intermediate gear X32 to receive the driving force, thereby allowing the photosensitive drum 20 to receive the driving force output by the drive unit through the developing roller 30, causing the photosensitive drum and the developing roller to rotate. In this embodiment, the power receiving unit is a gear.

[0556] Figure 131 FIG2 is a schematic diagram of the structure of the drive unit of the electronic imaging device in Example 24. The drive unit 1080 includes a gear portion 1080a, a small-diameter portion 1080b, and an inclined portion 1080c. During the process of contact and engagement between the power receiving unit and the drive unit of the electronic imaging device, the gear portion 1080a engages with the power receiving unit 21, while the telescopic rod X43 of the pressing member X40 extends to press the inclined portion of the drive unit 1080, thereby aligning the drive unit 1080. The detailed alignment process is described below.

[0557] Figure 132a Schematic diagram of the pressing member and the driving unit of the electronic imaging device when the process cartridge is in the initial position in Example 24. When the process cartridge 1 is installed in the electronic imaging device (not shown), and the door cover 101 of the electronic imaging device is not closed, the pressing member X40 of the process cartridge 1 is in the initial position, and the driving unit 1080 of the electronic imaging device 100 is still in a tilted state, as shown in FIG. Figure 132a As shown, the telescopic rod X43 is also retracted at this point. This structural diagram can also be used to describe the process of removing the process cartridge 1 from the electronic imaging device. When the door cover 101 is opened, the pushing portion 102 no longer pushes the push rod X41. As the first elastic member X41a recovers its elastic deformation, the push rod X41 is reset, simultaneously driving the connecting member X42 to return the telescopic rod X43. The elastic deformation of the second spring member X43a is also restored, effectively resetting the telescopic rod X43. Since the front end of the telescopic rod X43 no longer presses the inclined portion 1080c of the drive unit 1080, the drive unit 1080 returns to its tilted state.

[0558] Figure 132b Schematic diagram of the state of the pressing member and the driving unit of the electronic imaging device when the processing box in Example 24 is in the correct position. When the door cover 101 is closed, the pushing portion 102 acts on the push rod X41 of the processing box 1, and the push rod X41 moves forward, compressing the first spring X41a, while driving the connecting member X42 to move. The telescopic rod X43 connected to the connecting member X42 is subjected to tension and begins to slide outward along the cutout of the mounting portion X51b, while stretching and deforming the spring. When the front end of the telescopic rod X43 presses the inclined portion X1080c of the driving unit 1080, the driving unit 1080 is corrected along with the movement of the swing rod X43. Figure 132bAs shown, the axis of the drive unit 1080 is perpendicular to the bracket X51, i.e., it is in an aligned state. In this embodiment, when the drive unit 1080 is in the aligned state, the gear portion 1080a of the drive unit 1080 meshes with the power receiving unit 21, which transmits the driving force to the photosensitive drum via the intermediate gear X32 and the photosensitive drum gear X211. It should be noted that during the meshing process between the power receiving unit 21 and the drive unit 1080, the alignment member does not shift relative to the rotational axis of the photosensitive drum.

[0559] Example 25

[0560] like Figures 133 to 137 As shown, this embodiment provides another pressing member Y40 in the processing box 1, the pressing member Y40 is connected to the box body through the elastic member Y60, and is located at the same end of the box body as the power receiving unit 21, and the front end of the pressing member Y40 (the installation direction of the processing box 1) is also provided with a guide surface Y41 (an inclined surface or an arc surface) facing downward. Specifically, one end of the elastic member Y60 is fixed to the bracket Y51, and the other end is fixed to the pressing member Y40, so that the pressing member Y40 can return to its initial state after the external force is lost. Optionally, the elastic member Y60 can adopt a torsion spring or a tension spring. Furthermore, one end of the pressing member Y40 is sleeved on the photosensitive drum 20 so that the pressing member Y40 can rotate around the axis of the photosensitive drum 20. During the rotation of the pressing member Y40, the distance between at least part of the structure of the pressing member Y40 and the axis of the photosensitive drum does not change.

[0561] like Figure 133 and Figure 134 As shown, when the processing cartridge 1 is installed into the electronic imaging device along the Y1 direction, the pressing member Y40 contacts and interferes with the driving unit protective cover 1081 located above the driving unit 1080 in the electronic imaging device, causing the pressing member Y40 to move in the direction opposite to the Y1 direction under the force of the driving unit protective cover 1081, thereby squeezing the elastic member Y60, and at the same time, the side end of the processing cartridge at this position moves upward, causing the processing cartridge to tilt, as shown in FIG. Figure 135 As shown, as the processing box 1 continues to be installed, the pressing member Y40 moves upward over the drive unit protective cover 1081 and then moves to the opening above the drive unit protective cover 1081. At this time, the guide surface Y41 of the pressing member Y40 abuts against the drive unit protective cover 1081. Under the guidance of the guide surface Y41, the pressing member Y40 is smoothly inserted into the opening of the drive unit protective cover 1081 and contacts the drive unit 1080. Since the front end of the processing box 1 moves downward and drives the pressing member Y40 to move downward, the front end of the pressing member Y40 presses down the drive unit 1080 to move it downward and become basically coaxial with the power receiving unit 21 to receive power. At this time, the processing box 1 is successfully installed in the electronic imaging device.

[0562] When the process cartridge is finished and needs to be taken out from the electronic imaging device, the user may first press down the handle Y70 (eg Figure 136 At this time, the process cartridge rotates counterclockwise around the photosensitive drum 20, and the pressing member Y40 fixed relatively to the process cartridge also moves accordingly, so that the pressing member Y40 can avoid the interference of the drive unit protective cover 1081 and successfully detach from the drive unit protective cover 1081, as shown in FIG. Figure 137 As shown, the processing box is pulled out in the direction opposite to the installation direction, and finally the processing box is smoothly removed from the electronic imaging device.

[0563] Example 26

[0564] Figure 138 FIG. 2 is a schematic diagram of the structure of the processing box in Example 26. Figure 138 As shown, the process cartridge 1 includes a cartridge body Z50, a photosensitive drum 20, a developing roller 30, a pressing member Z40, and a bracket Z51 disposed on one side of the cartridge body. The cartridge body Z50 contains developer. A power receiving unit 21 is disposed at one end of the photosensitive drum 20 and is configured to receive the driving force from the driving unit 1080 to rotate the photosensitive drum 20. A developing roller gear 31 is also disposed at one end of the developing roller 30 to receive the driving force output by the driving unit to rotate the developing roller 30.

[0565] Specifically, the bracket Z51 includes a fixed post Z511, and the pressing member Z40 is mounted on the bracket Z51 via the fixed post Z511. Simultaneously, in the axial direction of the photosensitive drum 20, at least a portion of the pressing member Z40 is located within the outer peripheral surface of the photosensitive drum 20. During the process of contact and engagement between the power receiving unit 21 and the drive unit 1080 of the electronic imaging device, the pressing member Z40 can contact the drive unit 1080 of the electronic imaging device within the first planar region, thereby correcting the position of the drive unit. In this embodiment, the pressing member is a torsion spring. Specifically, the pressing member can be made of other materials and structures, as long as it can be movably mounted on the bracket and at least a portion of the pressing member is always located within the first planar region during the engagement between the power receiving unit and the drive unit. The materials and structures are not limited to those of the present application. The projection of the first planar region at least partially overlaps with the projection of the photosensitive drum.

[0566] Figure 139 FIG. 1 is a schematic diagram of the structure of the driving unit in the electronic imaging device. Figure 139 As shown, the driving unit 1080 includes a gear portion 1080a and a driving output portion 1080b, wherein, during the process of contact and engagement between the power receiving unit and the driving unit of the electronic imaging device, the driving unit 1080 of the electronic imaging device engages with the power receiving unit 21 while the gear portion 1080a engages with the developing roller gear 31 of the processing box 1.

[0567] Figures 140-142 Schematic diagram of the processing box in which the power receiving unit and the driving unit of the electronic imaging device are not in contact and engaged in embodiment 26. Figures 140-142 As shown, when the process cartridge 1 is installed in the electronic imaging device, the pressing member Z40 installed on the bracket gradually approaches the driving unit 1080 as the process cartridge moves. At this time, the pressing member Z40 is restricted by the structure of the electronic imaging device (not shown), and the pressing member Z40 is in an upwardly lifted state, as shown in FIG. Figure 140 As shown, at this time, the pressing member Z40 is at a position away from the axis of the power receiving unit 21. Figure 141 As shown, the pressing member Z40 and the driving unit 1080 are in a distanced state, and the driving unit 1080 is still in a tilted state, as shown in FIG. Figure 142 As shown, when the driving unit has not been straightened, the axis L1 of the driving unit 1080 is not parallel to the axis 2 of the photosensitive drum 20. Specifically, the driving output part 1080b of the driving unit 1080 is not aligned with the power receiving unit, that is, the power receiving unit of the processing box is not in contact with the driving unit of the electronic imaging device.

[0568] Figures 143-145 Schematic diagram of a process cartridge in which a power receiving unit is in contact and engaged with a drive unit of an electronic imaging device in Example 26. When the pressing member Z40 contacts the drive unit 1080 to form structural interference, the pressing member Z40 applies a aligning force to the drive output portion 1080b. After receiving the aligning force, the drive unit 1080 moves in a direction closer to the power receiving unit 21. The pressing member Z40 is in a downward position, pressing the drive unit 1080 to align. Figure 143 As shown, at this time, the pressing member Z40 is located close to the axis of the power receiving unit 21. Figure 144 As shown, the pressing member Z40 and the driving unit 1080 are in a close state, and the driving unit 1080 is in a straightened state, as shown in FIG. Figure 145 As shown, when the drive unit is aligned, the axis L1 of the drive unit 1080 and the axis L2 of the photosensitive drum 20 are parallel, or in other words, coaxial. Specifically, the drive output portion 1080b of the drive unit 1080 is aligned with the power receiving unit 21, i.e., the power receiving unit is in contact and meshing engagement with the drive unit of the electronic imaging device, enabling the drive unit 1080 to transmit the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate. Simultaneously, the gear portion 1080a of the drive unit 1080 is aligned and meshing engagement with the developing roller gear 31, thereby transmitting the driving force to the developing roller gear, causing the developing roller 30 to rotate.

[0569] Figure 1462 is a diagram showing the state of the pressing member in the twenty-sixth embodiment being in the contact position and the non-contact position. Figure 146 As shown, the dotted line of the pressing member Z40 indicates that the processing box 1 is inserted into the electronic imaging device. Due to the structural limitations of the electronic imaging device (not shown), the pressing member Z40 is in an upwardly lifted state, that is, the power receiving unit of the processing box and the drive unit of the electronic imaging device are not in contact and engagement. The solid line of the pressing member Z40 indicates that the pressing member Z40 contacts the drive unit 1080 to form structural interference, and the pressing member Z40 presses the drive unit 1080 to align it, that is, the power receiving unit 21 and the drive unit 1080 of the electronic imaging device are in a contact and engagement state. When the power receiving unit 21 and the drive unit 1080 of the electronic imaging device move from a non-contact state to a contact and engagement state, the pressing member Z40 is partially located inside the projected cross-section of the outer peripheral surface of the photosensitive drum 20, that is, the pressing member Z40 is partially located closer to the axis of the photosensitive drum 20.

The electronic imaging device 100 includes a door cover 101 that can be opened and closed, a pushing portion 102 that cooperates with the door cover 101, and a driving unit (not shown in the figure), which is a component that outputs driving force.

[0572] Figure 148 2 is a schematic structural diagram of a process cartridge in Example 27; Figure 149 FIG. 2 is another schematic diagram of the structure of the processing box in Example 27.

The pressing member AA40 is configured to engage with the drive unit 1080 to align the drive unit. The power receiving unit 21 is configured to receive the driving force output by the drive unit in the electronic imaging device. The cartridge body AA50 contains developer.

[0573] Figure 150 FIG2 is a partial view of the photosensitive drum and the developing roller in Example 27. Specifically, Figure 150As shown, the power receiving unit 21 is provided at the end of the developing roller and is used to engage with the driving unit of the electronic imaging device to receive the driving force outputted therefrom, thereby causing the developing roller 30 to rotate. Furthermore, an intermediate gear AA32 is provided on the developing roller 30, and a photosensitive drum gear AA211 is provided on the end of the photosensitive drum 20. The photosensitive drum gear AA211 engages with the intermediate gear AA32 to receive the driving force, thereby causing the photosensitive drum 20 to rotate. In this embodiment, the power receiving unit is the developing roller gear.

[0574] Figure 151 FIG2 is a partial view of the bracket in Example 27. Figure 151-Figure 1 As shown in FIG53 , a bracket AA51 is disposed at one end of the housing AA50 and is used to mount the pressing member AA40. Furthermore, the bracket AA51 includes a slide groove AA51a and a mounting portion AA51b. The pressing member AA40 includes a push rod AA41, a connector AA42, and a rocker arm AA43. The push rod AA41 is movably mounted in the slide groove AA51a. The rocker arm AA43 is rotatably mounted in the mounting portion AA51b. The push rod AA41 is connected to the rocker arm AA43 via the connector AA42. The push rod AA41 can drive the rocker arm AA43 to swing, thereby enabling the rocker arm AA43 to adjust the position of the drive unit within a first planar region. On a plane perpendicular to the axial direction of the photosensitive drum, the projection of the first planar region at least partially overlaps with the projection of the photosensitive drum.

[0575] Figure 152 FIG2 is a partial view of the rocker in Example 27. Figure 152 As shown, the rocker arm AA43 includes a first connecting portion AA43a, a second connecting portion AA43b and an abutting portion AA43c, wherein the first connecting portion AA43a is connected to the mounting portion AA51b of the bracket AA51, the second connecting portion AA43b is connected to one end of the connecting member AA42, and the abutting portion AA43c can realize the alignment of the driving unit 1080 during the movement.

Figure 153a As shown, the processing box also includes a first connecting portion AA43a, the first connecting portion AA43a of the swing arm AA43 is installed on the bracket AA51, and one of the second connecting portions AA43b is connected to the inner wall of the mounting portion AA51b via a first elastic member AA51a. The first elastic member AA51a can reset the swing arm AA43, that is, the swing arm AA43 can return to the initial position from the centered position. Figure 153bAs shown, the process cartridge further includes a second elastic member AA42. A second connecting portion AA43b is connected to one end of the connecting member AA42. The connecting member AA42 is connected to the push rod AA41 via a second elastic member AA42a. The second elastic member AA42a acts as a buffer to prevent excessive force from affecting the correct position of the push rod AA41. In the embodiment, the push rod AA41, the connecting member AA42, and the rocker arm AA43 together form the pressing member AA40. The operation of the pressing member AA40 will be described in detail later.

[0577] Figure 154a Schematic diagram of the pressing member and the driving unit of the electronic imaging device when the process cartridge is in the initial position in Example 27. When the process cartridge 1 is installed in the electronic imaging device (not shown), the door cover 101 of the electronic imaging device has not been closed. At this time, the pressing member AA40 of the process cartridge 1 is in the initial position, and the driving unit 1080 of the electronic imaging device 100 is still in a tilted state. Figure 154a As shown, at this time, the rocker arm AA43 is also in a tilted state.

[0578] Figure 154b This is a schematic diagram of the pressing member and the drive unit of the electronic imaging device when the process cartridge is in the correct position in Example 27. When the door cover 101 is closed, the pressing portion 102 acts on the push rod AA41 of the process cartridge 1, causing the push rod AA41 to move forward, driving the connecting member AA42. At this time, the swing rod AA43 connected to the connecting member AA42 is subjected to a tensile force and begins to extend outward. When the abutment portion AA43c abuts the recess 1080a of the drive unit 1080, the drive unit 1080 is aligned with the movement of the swing rod AA43, as shown in FIG. Figure 154b As shown, the drive unit 1080 is perpendicular to the bracket AA51, i.e., in an aligned position. In this embodiment, when the drive unit 1080 is in the aligned position, the gear portion 1080b of the drive unit engages with the power receiving unit 21, which transmits the driving force to the photosensitive drum via the intermediate gear AA32 and the photosensitive drum gear AA211. It should be noted that during the engagement between the power receiving unit 21 and the drive unit 1080, the pressing member AA40 is partially located within the projected cross-section of the outer peripheral surface of the photosensitive drum 20.

[0579] Example 28

[0580] This embodiment provides a structure of a processing box. Compared with the twenty-second and twenty-third embodiments, this embodiment does not provide a control mechanism on the processing box. Figure 154cAs shown, specifically, the process cartridge of this embodiment includes a cartridge body, a developing roller 30, a photosensitive drum 20, and a first gear CC32. The developing roller 30 and the photosensitive drum 20 are rotatably disposed in the cartridge body. The first gear CC32 is disposed at one end of the developing roller 30, and the gear disposed at one end of the developing roller 30 meshes with the gear disposed at one end of the photosensitive drum 20. When the process cartridge is installed in an electronic imaging device, the first gear CC32 abuts against the gear portion 1080a of the drive unit of the electronic imaging device, causing the developing roller 30 to mesh with the gear portion 1080a of the drive unit via the first gear CC32. As a result, through the meshing of the two, the drive unit of the electronic imaging device can transmit driving force to the developing roller 30 at an angle, causing the developing roller 30 to rotate, and then the developing roller 30 drives the photosensitive drum 20 to rotate, without requiring the drive unit of the electronic imaging device to move from its initial tilted state to a position where its axis is substantially parallel to or coaxial with the axis of the photosensitive drum. In the axial direction of the developing roller 30 , at least a portion of the first gear CC32 protrudes from the end of the photosensitive drum 20 .

[0581] Furthermore, the first gear CC32 is disposed at the end of the developing roller 30 and rotates coaxially with the developing roller 30. The first gear CC32 may be a bevel gear structure (eg Figure 154c ) Preferably, the upper teeth are designed as helical teeth so as to be better adapted to meshing with the helical teeth of the driving unit of the electronic imaging device.

[0582] In this embodiment, the power receiving unit located at the end of the photosensitive drum does not need to be meshed with the drive unit of the electronic imaging device for transmission, so the structure of the power receiving unit can also be eliminated. In this case, the photosensitive drum can be meshed with the developing roller at the driving end or the non-driving end by providing mutually cooperating transmission gears at the end of the photosensitive drum and the developing roller, so that the photosensitive drum can receive the driving force output from the drive unit of the electronic imaging device received by the above-mentioned first gear through the developing roller. Furthermore, the processing box also includes a second gear 31 and a third gear CC211, the second gear 31 is provided at one end of the developing roller 30, and the third gear CC211 is provided at one end of the photosensitive drum 20, and the third gear CC211 is meshed with the second gear 31, so that the driving force received by the first gear CC32 can be transmitted to the photosensitive drum 20 via the second gear 31 and the third gear CC211.

[0583] In another embodiment, a first gear CC32 is disposed at one end of the photosensitive drum 20, enabling the photosensitive drum to receive driving force from the inclined drive unit via the first gear and further transmit the driving force to the developing roller via the aforementioned transmission gear. Specifically, when the process cartridge is installed in an electronic imaging device, the photosensitive drum engages with the drive unit in the electronic imaging device via the first gear, enabling the photosensitive drum and the developing roller to receive driving force from the electronic imaging device.

[0584] Example 29

[0585] Figure 155 Schematic diagram of the structure of the processing box in Example 29, Figure 156 FIG. 2 is a partial schematic diagram of the first gear in Example 29. Figure 155 、 Figure 156 As shown, the process cartridge 1 includes a cartridge body CC50, a photosensitive drum 20, a developing roller 30, a pressing member CC40, a power receiving unit 21, a first gear CC32, and the cartridge body CC50. The cartridge body CC50 contains developer and includes a bracket CC51. The photosensitive drum 20 and developing roller 30 are rotatably mounted on the cartridge body CC50. The power receiving unit 21 is mounted at one end of the photosensitive drum 20 and has a power receiving portion CC21a for receiving the driving force output by the electronic imaging device drive unit 1080, thereby rotating the photosensitive drum 20. The first gear CC32 is arranged at the end of the developing roller 30 and is located at the same end of the box body CC50 as the power receiving unit 21, and is used to engage with the gear part of the driving unit 1080 of the electronic imaging device, thereby driving the driving unit 1080 to move toward the power receiving unit 21, so that the driving unit 1080 and the power receiving unit 21 are in contact and engaged, wherein in the axial direction of the developing roller 30, at least a portion of the first gear CC32 protrudes from the end of the photosensitive drum 20.

[0586] Furthermore, the pressing member CC40 is fixedly mounted on the bracket CC51 and is located at the same end of the box body CC50 as the power receiving unit 21. In the projection plane in the axial direction of the photosensitive drum, at least a portion of the pressing member CC40 is located inside the projection cross-section in the axial direction of the photosensitive drum 20. Specifically, in the projection plane perpendicular to the axis of the photosensitive drum 20, at least a portion of the pressing member CC40 is located inside the photosensitive drum 20. The pressing member CC40 includes a pressing portion, which refers to the portion where the pressing member CC40 contacts the drive unit. During the process of contact and engagement between the power receiving unit 21 and the drive unit of the electronic imaging device, the pressing member CC40 can contact the drive unit 1080 to achieve alignment of the drive unit. That is, the drive unit of the electronic imaging device can be aligned through the pressing member CC40, wherein aligning the position of the drive unit means making the axis of the drive unit and the axis of the photosensitive drum substantially parallel or coaxial.

[0587] In this embodiment, the pressing member CC40 and the bracket are integrally formed. It is understood that in other embodiments, the pressing member can also be fixed to the bracket in a movably connected manner. The pressing member CC40 can be used to move the drive unit 1080 between the inclined position and the straightened position. That is, when the process cartridge is just beginning to be installed in the electronic imaging device, the drive unit 1080 is tilted relative to the axis of the photosensitive drum, and the pressing portion of the pressing member CC40 abuts against the drive unit 1080. When the process cartridge is continued to be installed, the pressing portion of the pressing member CC40 applies a force to the drive unit 1080, thereby causing the drive unit 1080 to reach the straightened position, causing the pressing member CC40 to have a certain displacement relative to the photosensitive drum.

[0588] Continue to refer to Figure 156 As shown, the first gear CC32 has a protrusion CC32a, which is distributed in a spiral pattern. When the driving unit 1080 of the electronic imaging device is engaged with the first gear CC32, the first gear CC32 can drive the driving unit 1080 toward the power receiving unit 21, so that the driving unit 1080 of the electronic imaging device is in contact and engaged with the power receiving unit 21.

[0589] Figure 157 FIG. 1 is a schematic diagram of the structure of the driving unit in the electronic imaging device. Figure 157 As shown, the driving unit 1080 of the electronic imaging device includes a gear portion 1080a, a small diameter portion 1080b and a driving output portion 1080c, wherein, during the process of the gear portion 1080a engaging and rotating with the first gear CC32 of the processing box 1, the power receiving unit 21 contacts and engages with the driving output portion 1080c of the driving unit 1080.

[0590] Figure 158a Schematic diagram of the process box in which the photosensitive drum power receiving unit is not in contact with the driving unit in the electronic imaging device in Example 29. Figure 158a As shown, the process cartridge 1 further includes a third gear CC211 and a second gear 31. The third gear CC211 is disposed at one end of the photosensitive drum 20, and the second gear 31 is disposed at one end of the developing roller 30. The second gear 31 and the third gear CC211 are meshed with each other, so that the power receiving unit 21 receives the driving force of the driving unit 1080 of the electronic imaging device and transmits it to the third gear CC211. The third gear CC211 then transmits the driving force to the second gear 31, thereby driving the developing roller 30 to rotate. In this embodiment, the third gear CC211 and the power receiving unit 21 are integrally formed.

[0591] When the process cartridge 1 is installed in the electronic imaging device, at the beginning, the pressing member CC40 installed on the bracket will gradually approach the driving unit 1080 of the electronic imaging device as the process cartridge moves, but will not contact the small diameter portion of the driving unit 1080. Figure 158a As shown, at this time, the pressing member CC40 and the drive unit 1080 are separated, the drive unit 1080 is still in an inclined state, and the gear portion 1080a of the drive unit 1080 is not in contact with the protrusion CC32a of the first gear CC32. Furthermore, when the drive unit of the electronic imaging device has not been aligned, the axis L1 of the drive unit 1080 and the axis L2 of the photosensitive drum 20 are not parallel. Specifically, the drive output portion 1080b of the drive unit 1080 of the electronic imaging device is not aligned with the power receiving unit, that is, the power receiving unit 21 of the process cartridge is not in contact with the drive unit 1080 of the electronic imaging device.

[0592] When the installation continues, when the pressing member CC40 contacts the driving unit 1080 of the electronic imaging device to form structural interference, the pressing member CC40 applies a straightening force to the driving unit 1080 of the electronic imaging device, and the pressing member CC40 has a downward state, pressing the driving unit 1080 to straighten it, such as Figure 158b As shown, at this time, the pressing member CC40 and the driving unit 1080 of the electronic imaging device are in a close state, and the driving unit 1080 of the electronic imaging device is in an aligned state. When the driving unit 1080 is in the aligned state, the axis L1 of the driving unit 1080 and the axis L2 of the photosensitive drum 20 are in a parallel state, or in a coaxial state. In this state, the gear portion 1080a of the driving unit 1080 is engaged with the first gear CC32. Since the gear portion 1080a of the driving unit 1080 is a helical tooth, and the protrusion CC32a of the first gear CC32 is also spirally distributed, when the driving unit 1080 and the first gear CC32 are engaged and rotated, the driving unit 1080 moves in a direction close to the power receiving unit 21.

[0593] Specifically, the driving output part 1080c of the driving unit 1080 of the electronic imaging device is aligned with the power receiving part CC21a of the power receiving unit 21, that is, the power receiving unit and the driving unit are in contact and engaged, so that the driving unit 1080 transmits the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate, and then transmits the driving force to the developing roller 30 through the third gear CC211 and the second gear 31, thereby realizing the rotation of the developing roller 30.

[0594] Figure 159 FIG2 is a schematic diagram showing the contact force between the driving unit and the first gear in the electronic imaging device in Example 29. Figure 159As shown, when the driving unit 1080 of the electronic imaging device and the first gear CC32 are in a meshing rotational state, the meshing of the helical teeth of the gear portion 1080a of the driving unit 1080 with the protrusion CC32a of the first gear CC32 generates an axial force F1. Under the action of the axial force F1, the driving unit 1080 tends to move toward the side close to the power receiving unit 21. In other words, the driving unit 1080 approaches and contacts the power receiving portion CC21a of the power receiving unit 21. At the same time, the first gear CC32 is subjected to the axial force F2 due to the meshing, causing the first gear CC32 to move toward the side away from the power receiving unit 21. Since the first gear CC32 is restricted by the structure of the processing cartridge 1, it will not undergo axial movement.

[0595] Example 30

[0596] An embodiment of the present application provides an electronic imaging device, which includes a processing box, a driving unit and a driving unit protective cover, wherein the driving unit protective cover is arranged outside the driving unit.

[0597] The electronic imaging device may be a printer, a copier, a scanner-copier, etc., without limitation. The following description of the solution takes a printer as an example. The process cartridge may be a toner cartridge, an ink cartridge, etc.

[0598] Figure 160 This is a structural diagram of the electronic imaging device provided in an embodiment of the present application before the pressing member is installed. Figure 161a for Figure 160 A partial enlarged view of area A is shown.

[0599] like Figure 160 and Figure 161a As shown, the drive unit protective cover 1081 is disposed outside the drive unit 1080. Before the pressing member is installed, the drive unit 1080 is supported by a drive head push member (not shown) in the electronic imaging device and is in an inclined state, with the rotation axis L1 of the drive unit 1080 and the central axis L2 of the drive unit protective cover 1081 forming an angle α.

[0600] Figure 161b This is a schematic diagram of the structure of the processing box provided in the embodiment of the present application. Figure 3 As shown, the process cartridge 1 includes a cartridge body A10, a photosensitive drum 20, a developing roller 30, a bracket A11, and a power receiving unit 21. The cartridge body A10 contains a developer. The power receiving unit 21 is disposed at one end of the photosensitive drum 20. The power receiving unit 21 is in transmission connection with the driving unit 1080. In this embodiment, the power receiving unit 21 engages with the driving unit 1080 to receive the driving force of the driving unit.

[0601] In the present application, the end of the process box having the power receiving unit is defined as the driving end, and the end of the process box 1 having the conductive unit (not shown) is defined as the power end.

[0602] Specifically, the bracket A11 includes a first fixed column A111 and a through hole A112. The power receiving unit 21 is fixed to the bracket A11 through the through hole A112 and exposed to the outside of the through hole A112 to receive the driving force of the driving unit (i.e., driving unit) 1080 of the electronic imaging device (not shown in the figure). In addition, the first fixed column A111 is arranged above and / or in front of the power receiving unit 21 relative to the axial direction of the photosensitive drum 20.

[0603] In order to transform the driving unit 1080 of the electronic imaging device from its tilted initial position to a horizontal position capable of engaging with the power receiving unit 21, an embodiment of the present application provides a pressing member for the electronic imaging device, which is used in conjunction with a process cartridge. The pressing member is detachably mounted in the electronic imaging device and can be used independently in the electronic imaging device or in conjunction with process cartridges of different structures.

[0604] Figure 162 A schematic diagram of the structure of the pressing member provided in the embodiment of the present application is shown in FIG. Figure 162 As shown, the pressing member DD40 is independently and detachably mounted on the driving unit protection cover 1081. The pressing member DD40 includes a first main body portion DD41, a deformable portion DD42 connected to the first main body portion DD41, and a pressing portion DD44.

[0605] In some embodiments, the pressing member DD40 may be shaped as a circular ring. In other embodiments, the pressing member DD40 may have other shapes as long as they do not interfere with the installation and operation of the process cartridge. Furthermore, the various structures included in the pressing member DD40 may be integrally formed or connected together via a snap-fit ​​structure, welding, or other connection methods, without limitation herein.

[0606] The drive unit protective cover 1081 has curved sidewalls, and the first main portion DD41 of the pressing member DD40 is annular and sheet-like, and can engage with the sidewalls of the drive unit protective cover 1081. The first main portion DD41 can be made of a thin sheet metal or plastic. This application does not impose any restrictions on its material, as long as it does not affect its installation and the deformation and recovery of the deformable portion DD42.

[0607] The deformable portion DD42 is connected to the first main portion DD41. When the pressing member DD40 abuts the drive unit 1080, the deformable portion DD42 can deform and drive the drive unit 1080 from a tilted state to a straightened state. It should be noted that when the drive unit 1080 is in the straightened state, the rotation axis L1 of the drive unit 1080 and the central axis L2 of the drive unit protective cover 1081 are substantially aligned, that is, the angle α is zero or close to zero.

[0608] In this embodiment, the deformable portion DD42 is an arc-shaped elastic sheet. The deformation of the deformable portion DD42 can be generated by utilizing its own flexible force, or it can be achieved by providing an elastic member on the pressing member DD40. The elastic member can be a component such as a spring or a magnet with a certain elastic force (which can drive the drive unit 1080 to align). Exemplarily, the elastic member is an elastic sheet, one end of which is connected to the main body DD42 and the other end is connected to the deformable portion DD42, thereby enabling the deformable portion DD42 to deform.

[0609] The deformable portion DD42 is connected to a pressing portion DD44, and the pressing member DD40 contacts the driving unit 1080 through the pressing portion DD44. Specifically, the pressing portion DD44 can be a surface structure or a linear structure provided on the deformable portion DD42. For example, the pressing portion DD44 can be an arc-shaped surface convex toward the driving unit 1080.

[0610] In actual use, the pressing member DD40 abuts the drive unit 1080 via the pressing portion DD44, causing the drive unit 1080 to adjust from a tilted state to a straightened state. When the pressing portion DD44 of the pressing member DD40 abuts the drive unit 1080, the deformable portion DD42 deforms. Under the deformation force of the deformable portion DD42, the pressing member DD40 drives the drive unit 1080 from a tilted state to a straightened state, and the deformation of the deformable portion DD42 is restored.

[0611] In some embodiments, the pressing member DD40 further includes an abutment portion DD43 located at an end of the deformable portion DD42 away from the first main portion DD41. Specifically, the abutment portion DD43 may be formed by bending from one end of the deformable portion DD42. The abutment portion DD43 may abut against the drive unit protective cover 1081.

[0612] When the drive unit 1080 is in the upright position, the contact portion DD43 contacts the drive unit protective cover 1081, so that the pressing portion DD44 no longer contacts the drive unit 1080. This prevents the drive unit 1080 from rubbing against or even interfering with the pressing member DD40 during rotation. Therefore, the pressing member DD40 provided in this application does not affect the rotation of the drive unit 1080, and can also avoid friction damage between the pressing member DD40 and the drive unit 1080, thereby increasing the service life of the pressing member DD40.

[0613] In order to improve the installation stability of the pressing piece DD40 and the drive unit protection cover 1081, as shown in FIG. Figure 162 As shown, the pressing member DD40 further includes a fixing portion, and the pressing member DD40 is detachably mounted on the driving unit protective cover through the fixing portion.

[0614] Specifically, the fixing portion includes a first fixing end DD45 and a second fixing end DD46 bent along the two ends of the first main body DD41. The pressing member DD40 is clamped on the side wall of the drive unit protective cover 1081 through the first fixing end DD45 and the second fixing end DD46. The first fixing end DD45 and the second fixing end DD46 can be hook structures.

[0615] Figure 163 This is a schematic diagram of the structure of the electronic imaging device provided in this application after the pressing member is installed. Figure 164 for Figure 163 A partial enlarged view of area B is shown. Figure 165 This is a schematic diagram of the assembly structure between the pressing member and the drive unit protective cover provided in this application. Figure 163 、 Figure 164 and Figure 165 As shown, the drive unit protective cover 1081 is recessed along the axial direction to form a groove. In this embodiment, the groove includes a first groove 1081a and a second groove 1081b that are spaced apart. The first groove 1081a includes a first end wall 10811, and the second groove 1081b includes a second end wall 10812. The first fixed end DD45 abuts against the first end wall 10811, and the second fixed end DD46 abuts against the first end wall 10812, so that the pressing member is installed on the drive unit protective cover 1081.

[0616] In this embodiment, the first fixing end DD45 and the second fixing end DD46 are both hook structures, which are detachably connected to the drive unit protection cover 1081 through the hook structure, so as to facilitate installation and replacement.

[0617] In order to further improve the stability of the overall structure, the first end wall 10811 and the second end wall 10812 may be provided with a clamping rib, and correspondingly, the first fixed end DD45 and the second fixed end DD46 may be provided with a protrusion or a groove to make the snap connection more stable.

[0618] In other embodiments, the first end wall 10811 and the second end wall 10812 may also be walls extending in the axial direction of the drive unit protective cover 1081, or other optional side walls, which are not limited here. The fixing of the pressing member DD40 to the drive unit protective cover 1081 along the axis L2 is not limited. For example, the width of the first main body DD41 of the pressing member DD40 may be adjusted to closely match the axial dimension of the drive unit protective cover 1081 to prevent axial shaking of the pressing member DD40 on the drive unit protective cover 1081.

[0619] like Figure 163 and Figure 164 As shown, before the pressing member DD40 is installed separately into the printer, the door cover of the printer is open, and the drive unit 1080 will not be straightened by external force but remains in a tilted state. At this time, the pressing member DD40 can be manually installed on the drive unit protective cover 1081.

[0620] like Figure 163 and Figure 165 As shown, the pressing member DD40 is pressed along Figure 163 The printer is fed into the direction of the middle arrow M. When it contacts the top of the drive unit protection cover 1081, a certain pressing force is applied to the pressing member DD40 so that the first fixed end DD45 is engaged with the first end wall 10811 of the drive unit protection cover 1081, and the second fixed end DD46 is engaged with the second end wall 10812 of the drive unit protection cover 1081. Figure 164 As shown, the pressing member DD40 contacts the drive unit 1080 through the pressing portion DD44. Since the door cover is not closed, the pressing member DD40 abuts against the drive unit 1080 in a tilted state. Since the portion of the drive unit 1080 that is tilted and offset from the periphery of the drive unit protective cover 1081 abuts against the pressing portion DD44, the deformable portion DD42 adaptively deforms and maintains the deformed state. At this time, the deformation restoring force generated by the deformation of the deformable portion DD42 is always applied to the drive unit 1080. The overall state of the pressing member DD40 is the first state, and the drive unit 1080 is adjusted from the tilted state to the straightened state.

[0621] Furthermore, in order to facilitate installation and cooperation with the processing box, the processing box provided in the present application also includes a box pressing member AB40, and the box pressing member AB40 is arranged at one end of the processing box.

[0622] Figure 166 A schematic diagram of a partial structure of a printer provided in an embodiment of the present application is shown. Figure 167 for Figure 166 A partial enlarged view of area C is shown. Figure 168 This is a schematic diagram of the structure of the processing box provided in the embodiment of the present application. Figures 166-168 As shown, the processing box provided by this application can be any processing box that can cooperate with the pressing member, and this application does not limit the specific structure of the processing box. Figure 168 As shown, in some embodiments, the processing box has a swingable box pressing member AB40. In addition, the processing box according to this embodiment may not have any pressing structure such as the box pressing member AB40, so the pressing member in this embodiment is universally applicable in cooperation with the processing box.

[0623] Specifically, when Figure 168 The process cartridge is installed into the printer in the same direction as the pressing member DD40, that is, it is fed into the electronic imaging device in the direction of arrow M. Figure 166 and Figure 167 As shown, after installation, the processing box is located at the position of the pressing member DD40, and the box pressing member AB40 thereon can be directly above the pressing member DD40, for example, overlapped on the pressing member DD40. At this time, since the thickness of the pressing member DD40 in the direction of the vertical axis L2 of this embodiment is small enough, the pressing member DD40 will not affect the box pressing member AB40 on the processing box and its function, that is, it can be applied to processing boxes of various structures.

[0624] Further, the state of the process cartridge when working is described, such as Figure 169 As shown, when the printer door cover is closed, the drive unit 1080 enters a state where it can be swung by an external force. Consequently, the deformation recovery force of the deformable portion DD42 applied to the drive unit 1080 drives the drive unit 1080 and adjusts it from a tilted state to a straightened state. As the drive unit 1080 straightens, the photosensitive drum power receiving head (not shown) on the process cartridge gradually engages well with the drive unit 1080. At this point, the recovery of the deformable portion DD42 causes the abutment portion DD43 to move into abutment with the drive unit protective cover 1081, thereby removing the pressing portion DD44 from contact with the drive unit 1080. This allows the drive unit 1080 to rotate without friction or even interference with the pressing member DD40. This is the second state of the pressing member DD40, and subsequent normal printing can proceed.

[0625] Example 31

[0626] This embodiment also provides a pressing component, which is a further improvement based on the embodiment 30. The unexplained parts are the same as those in the aforementioned embodiments and will not be repeated for the sake of simplicity.

[0627] Figure 170 A schematic diagram of the structure of the pressing assembly provided in the embodiment of the present application is shown in FIG. Figure 170 As shown, the pressing assembly EE90 of this embodiment can be independently and detachably installed on the driving unit protection cover 1081. The pressing assembly EE90 includes a frame EE91 and a pressing member EE40 connected to the frame EE91.

[0628] In some embodiments, along the length direction of the frame EE91, the frame EE91 includes a first end EE92 and a second end EE93, the first end EE92 of the frame EE91 is connected to the pressing member EE40, and the second end EE93 of the frame EE91 is detachably connected to the end wall (not shown) of the processing box accommodating chamber of the electronic imaging device.

[0629] To facilitate installation of the pressing assembly E90, the pressing assembly EE90 is adapted to the width of the process cartridge housing within the printer body. When the pressing assembly EE90 is installed within the printer body, the first end EE92 and the second end EE93 of the frame EE91 are respectively connected to the two end walls of the process cartridge housing of an electronic imaging device (e.g., a printer). In some embodiments, the frame can be mounted on corresponding structures on the two end walls of the printer's process cartridge housing.

[0630] Specifically, the structure of the pressing member EE40 is the same as that of the pressing member DD40 described in Example 1, and is installed on the driving unit protective cover 1081 located on one side of the interior of the printer body in the same installation manner, which will not be repeated here.

[0631] The first end EE92 of the frame EE91 is bent to form a first fixing portion EE921, and the second end EE93 of the frame EE91 is bent to form a second fixing portion EE931. The first fixing portion EE921 (first end) and the second fixing portion EE931 (second end) may be stepped. In some embodiments, the frame EE91 may be a plastic component, a sheet metal component, or an elastically deformable component. Preferably, its thickness does not affect the installation of the process cartridge and its coexistence with the process cartridge. If a deformable component is used, it can avoid the installation of the process cartridge while not affecting the operation of the process cartridge.

[0632] The first end EE92 of the frame EE91 can be connected to the pressing member EE40 via a first fixing portion EE921. The second end EE93 of the frame EE91 can be removably connected to a connecting structure on the end wall of the electronic imaging device via a second fixing portion EE931. The connecting structure can be a guide rail, a sidewall step, or other structure. For example, the connection between the second fixing portion EE931 and the connecting structure can be a snap-on connection, abutment, or plug-in connection, which is not limited herein.

[0633] It can be understood that by setting the frame EE91, the pressing component EE90 can be positioned quickly and accurately when installed, and the pressing part EE40 can be installed without carefully finding the position in advance. In particular, for user operation, the convenience of installing the pressing part EE40 is greatly increased. For example, when the processing box needs to be replaced or the processing box needs to be taken out and reinstalled, since the pressing component EE90 occupies a certain length of space, it can be clearly identified whether the pressing component EE90 / pressing part EE40 has been installed in the printer in advance, which serves as a clear reminder to the user.

[0634] According to the pressing assembly provided by the present application, the pressing member can be detachably installed in the printer independently or together with the frame. When the pressing member can be detachably installed in the printer independently, the pressing member can be first installed in the printer, the process cartridge can then be installed in the printer, and then the pressing member can be removed from the printer. This method is applicable to, but not limited to, removing the pressing member during the door cover closing operation, and is not limited to simultaneously utilizing other structures on the process cartridge to adjust the drive unit 1080 from a tilted state to a straightened state.

[0636] The embodiment of the present application also provides a pressing assembly that can be detachably installed in a printer. The pressing assembly can be used alone in the printer, or can work in the printer in conjunction with a processing cartridge of a different structure.

[0637] As described in Example 30, before the pressing member is installed, the driving unit 1080 is supported by the driving head pushing member in the printer and is in a tilted state, and the rotation axis L1 of the driving unit 1080 forms an angle α with the central axis L2 of the driving unit protective cover 1081.

[0638] Figure 171 Another structural diagram of the pressing component provided in the embodiment of the present application is as follows Figure 171As shown, the pressing assembly FF90 can be independently and detachably mounted on the drive unit protective cover 1081. The pressing assembly FF90 includes: a second main body FF91, a pressing member FF40 mounted on the second main body FF91, and a deformable member FF92. The pressing member FF40 is connected to the second main body FF91 via the deformable member FF92, and the pressing member FF40 reciprocates under the deformation of the deformable member FF92.

[0639] The second main body FF91 can be constructed from thin plastic or sheet metal. This application does not impose any material restrictions, as long as it does not affect its installation and the deformation and recovery of the pressing member FF40 and the deformable member FF92. Specifically, positioning structures are provided on both sides of the second main body FF91. These structures mate with connecting structures on either side of the printer's interior. These connecting structures can be, for example, guide rails, sidewall steps, or other structures. When the second main body FF91 is mounted on the printer using the positioning structures, the positioning structures engage with the printer's connecting structures.
