Description

Technical Field

[0001] This application relates to the field of image forming technology, and more specifically to a processing box. Background Technology

[0002] In existing technologies, electro-imaging devices typically include a drive unit for outputting rotational driving force. A processing cartridge is detachably mounted on the electro-imaging device and cooperates with the drive unit to receive the rotational driving force output by the drive unit. Generally, the processing cartridge includes a power receiving unit, a developing unit, a developer, a toner control unit, and a housing for accommodating these units. The power receiving unit is axially positioned at one end of the processing cartridge along the developing unit. Depending on the type of processing cartridge structure, some processing cartridges may also include a photosensitive unit, a charging unit, a cleaning unit, and a stirring unit. When the processing cartridge is installed in the electro-imaging device, the power receiving unit engages with the drive unit of the electro-imaging device, thereby transmitting the rotational driving force output by the drive unit to the processing cartridge to drive the rotating units (such as the developing unit, photosensitive unit, and stirring unit) inside the processing cartridge to rotate, thus participating in the developing process of the electro-imaging device.

[0003] However, in the existing technology, the initial state of the drive unit is tilted, that is, the drive unit and the power receiving unit are not coaxial. During the contact and engagement process of the power receiving unit and the drive unit, structural interference will occur between the two, making it difficult or impossible for the power receiving unit and the drive unit to accurately engage and transmit driving force. This causes the power receiving unit and the drive unit to take a certain amount of time to engage, affecting the working efficiency of the processing box. Summary of the Invention

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

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] This application provides a processing box, which includes:

[0007] Box body;

[0008] A photosensitive drum, which is rotatably disposed within the housing;

[0009] A developing roller, which is rotatably disposed on the cartridge body;

[0010] A hub is disposed at one end of the photosensitive drum, and a gear portion is provided on the outer circumference of the hub;

[0011] A power receiving unit is disposed at one end of the housing. The power receiving unit is used to receive the rotational driving force and transmit it to the hub to make it rotate.

[0012] A developing roller gear is disposed at one end of the developing roller and is used to mesh with the gear portion of the hub.

[0013] After receiving driving force, the hub can drive the photosensitive drum to rotate and transmit the driving force to the developing roller gear through the gear part of the hub, thereby driving the developing roller to rotate.

[0014] A pressing element is fixedly disposed on the housing and located at the same end of the housing as the power receiving unit. The distance between the pressing element and the axis of the photosensitive drum does not change.

[0015] Compared with the prior art, this application enables a smoother contact and engagement process between the photosensitive drum or developing roller of the processing cartridge and the drive unit of the electro-imaging device, greatly saving the contact and engagement time between the photosensitive drum or developing roller and the drive unit, and improving the working efficiency of the processing cartridge.

[0296] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0297] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0298] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0299] Figure 1 , Figure 2 This is a schematic diagram of the drive unit in the prior art where the processing box is not installed in the electronic imaging device. Figure 1 , Figure 2As shown, the electronic imaging device (not shown in the figure) includes a drive unit 1080, which has a power transmission component 1080e for transmitting rotational driving force to the processing box. Specifically, the drive unit 1080 is supported by the support portion 1085a of the support member 1085. Further, the first contact portion 1080h abuts against the first contact protrusion 1004 provided in the electronic imaging device. At the same time, the pressing member 1003 applies a pushing force FF2 to the pressed portion 1080i of the drive unit 1080 through the spring 1006, causing the second contact portion 1080j to contact the second contact protrusion 1005. At this time, the drive unit 1080 is in the initial position. When viewed along the direction parallel to the axis of the support member 1085, i.e., the direction of arrow HH, the axial direction EE of the drive unit 1080 is inclined relative to the center RR of the support portion 1085a.

[0300] 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 drive unit 1080, so that the drive unit 1080 changes from the tilted state in the initial position to be parallel to the axis of the support member 1085, so as to successfully match and engage with the power receiving unit and transmit driving force.

[0301] However, during the contact and engagement of the power receiving unit and the drive unit 1080, structural interference will occur between them, making it difficult or impossible for the power receiving unit and the drive unit 1080 to accurately engage and transmit power. As a result, it takes a certain amount of time for the power receiving unit and the drive unit 1080 to engage, which will also affect the working efficiency of the processing box.

[0302] Example 1

[0303] This 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 covers the driving unit 1080.

[0304] The electronic imaging device can be a printer, copier, or multifunction scanner / copier, etc., and is not limited here. The following explanation uses a printer as an example. The processing cartridge can be a toner cartridge, ink cartridge, etc.

[0305] A processing cartridge typically consists of a toner hopper unit and a waste toner hopper unit. The toner hopper unit includes a developing roller, a toner discharge blade, a toner delivery roller, and a stirring frame, while the waste toner hopper unit includes a photosensitive drum, a charging roller, and a cleaning blade. The processing cartridge usually also contains developer and a power receiving unit that receives external driving force. The power receiving unit includes a drive head and drive gear located at one end of the photosensitive drum. Furthermore, the processing cartridge also includes positioning components that cooperate with the machine.

[0306] The developing roller, driven by a motor, rotates to transfer developer onto the photosensitive drum. The toner ejector blade adjusts the uniformity of the developer on the developing roller. The agitator loosens the developer within the toner cartridge unit. The charging roller charges the photosensitive drum, and the cleaning blade removes excess developer from the drum after development.

[0307] Figure 3 This is a schematic diagram of the processing box in this application. Figure 3 As shown, the processing 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 developer, and the photosensitive drum 20 and the developing roller 30 are rotatably disposed 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, for engaging with the drive unit of the electronic imaging device to receive the driving force output by the drive unit of the electronic imaging device.

[0308] 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 exposed outside the through hole A112 to receive the driving force output by the drive unit 1080. The first fixing post A111 is positioned above and / or in front of the power receiving unit 21 relative to the axial direction of the photosensitive drum 20.

[0309] In order to change the drive unit 1080 from its initial tilted state to a horizontal state that can engage with the power receiving unit 21, the processing box 1 also includes a pressing member A40. The pressing member A40 is fixedly disposed on the box body A10 and 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 of the processing box 1 so that the drive unit 1080 is aligned.

[0310] Furthermore, the pressing member A40 is detachably mounted on the first fixing post A111, thereby fixing it to the bracket A11. Simultaneously, at least a portion of the pressing member A40 is located outside the power receiving unit 21 along the axial direction of the photosensitive drum 20. Optionally, the pressing member A40 is configured as a roller, with its outer surface serving as a guiding pressing surface. This guiding pressing surface guides and presses the drive unit, aligning it in the correct position. Further, the outer surface of the roller may be coated with a rubber coating. This rubber coating prevents structural interference that could cause wear to the drive unit when the pressing member A40 contacts the drive unit 1080.

[0311] Figures 4 to 6 This is a schematic diagram illustrating the contact and engagement process between the power receiving unit of the processing box and the drive unit of the electronic imaging device in this application. Figure 4As shown, when the processing box 1 is installed into the electronic imaging device along the Y1 direction, the pressing member A40 fixed on the bracket also gradually moves closer to the driving unit 1080 as the processing box moves. When the pressing member A40 contacts the driving unit 1080 and forms 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 closer 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 engagement of the power receiving unit 21 and the driving unit 1080, the pressing member A40 always remains parallel to the axis 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 its initial position to a position parallel to the axis of the support member A1085. At this time, the pressing member A40 is positioned above and / or in front of the power receiving unit 21 relative to the axis of the photosensitive drum 20. Finally, the drive unit 1080 and the power receiving unit 21 successfully engage, enabling the drive unit 1080 to transmit driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate.

[0312] In this embodiment, a pressing member is provided on the processing box, and the pressing member A40 forces the drive unit 1080 to move from the initial tilt position to a position that is 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 pressing member does not coincide with the projection of the photosensitive drum at all. This makes the contact and engagement process between the power receiving unit and the drive unit smoother, greatly saving the contact and engagement time between the power receiving unit and the drive unit, and improving the working efficiency of the processing box.

[0313] Example 2

[0314] This embodiment provides another processing box, and the parts not shown are the same as the processing box in Embodiment 1.

[0315] like Figure 7 and Figure 8 As shown, the processing box 1 also includes a movable positioning member B50, which is movably disposed on the bracket B11 and located at the same end as the power receiving unit 21. The positioning member B50 is capable of displacement relative to the bracket B11 in a first direction, wherein the first direction is the height extension direction of the processing box. Figure 8 (in the Z direction). Further, the bracket B11 is provided with a sliding groove B15, which can be a rectangular groove, a circular groove, or other regular or irregular structure, and is not limited here. The positioning member B50 is slidably disposed in the sliding groove B15, so that the positioning member B50 can move relative to the box body along the sliding groove B15.

[0316] When the processing box 1 is installed into the electronic imaging device along the forward direction (the installation direction of the processing box) via the mounting guide rail B900 on the inner side of the electronic imaging device, 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 component B50 can move relative to the housing, and during installation, the positioning component B50 is supported on the mounting rail B900, the housing of the processing housing 1 can undergo a certain displacement relative to the mounting rail B900 of the electronic imaging device during installation. The pressing component B40 located at the end of the housing also moves a certain amount relative to the drive unit 1080 inside the electronic imaging device or the mounting rail B900 of the electronic imaging device (at least vertically). Through this movement, the pressing component B40 can achieve a certain upward displacement relative to the drive unit 1080. After the processing housing is installed in place, it can move downwards to press down on the drive unit 1080, making the drive unit 1080 and the power receiving unit 900 essentially coaxially mesh to transmit driving force. Furthermore, the pressing component B40 forces the drive unit 1080 from its initial tilted position to a position approximately parallel to the axis of the photosensitive drum, and in a plane perpendicular to the axis of the photosensitive drum, the projection of the pressing component does not coincide with the projection of the photosensitive drum.

[0317] In this embodiment, due to the setting of the positioning member B50, the pressing member B40 is installed into the electronic imaging device in the processing box 1. The positioning member B50 can move relative to the box body along the slide groove B15, and drive the pressing member B40 set in 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 and avoid mutual interference.

[0318] In addition, the technical solutions of Embodiment 1 and Embodiment 2 described above can also be used in combination. For example, the movable positioning component of Embodiment 2 can be applied to the processing box of Embodiment 1 to increase functionality 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.

[0319] Example 3

[0320] This embodiment provides another pressing component, which is a further improvement based on Embodiment 2. The parts not described are the same as those in the foregoing embodiments, and will not be repeated for the sake of simplicity.

[0321] like Figure 9 and Figure 10As shown, the processing box 1 also includes a movable positioning member C50 and an elastic telescopic member C60. The positioning member C50 is disposed on the bracket C11 and located at the same end of the box body as the power receiving unit 21. The positioning member C50 is connected to the bracket C11 via the elastic telescopic member C60, thereby allowing the positioning member C50 to move relative to the processing box body. The processing box 1 also 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 is a guiding pressing surface.

[0322] When the processing box 1 is installed into the electronic imaging device along the forward direction (installation direction of the processing box) via the mounting guide C900 on the inner side of the electronic imaging device, the positioning member C50 is supported by the mounting guide C900 on the inner side of the electronic imaging device and moves forward along the mounting guide C900. Since the positioning member C50 can move relative to the processing box 1, and during the installation process, the positioning member C50 is supported on the mounting guide C900, therefore, the processing box 1 can move a certain amount relative to the mounting guide C900 of the electronic imaging device during the installation process.

[0323] Specifically, during the installation of the processing box 1 into the electronic imaging device, the pressing component C40 first touches the baffle 1081 located on the outer periphery of the drive unit 1080, thereby causing the entire processing box to move upward relative to the mounting guide rail C900 to avoid high points during the assembly process. After the processing box is completely installed in place, it also moves downward to the designated position. During the downward movement of the processing box, the pressing component C40 located in front of it also moves a certain amount relative to the drive unit 1080 or the mounting guide rail C900 inside the electronic imaging device (at least vertical movement is possible) as the processing box moves as a whole.

[0324] like Figure 11 and Figure 12As shown, when the pressing component C40 fixed on the bracket C11 gradually approaches and contacts the drive unit 1080 as the processing box moves, the gear portion C40a of the pressing component C40 and the gear portion C1081b of the drive unit 1080 form structural interference and mesh. Since the gear module of the pressing component C40 and the gear module of the drive unit 1080 are slightly different, after the two mesh for several tooth profiles, the pressing component C40 and the drive unit 1080 will experience tooth tipping. At the same time, since the pressing component C40 is fixed relative to the processing box, when tooth tipping occurs, the drive unit 1080 can move from the initial inclined position to a position that is approximately parallel or coaxial with the axis of the power receiving unit 21 by meshing with the pressing component C40. In the plane perpendicular to the axis of the photosensitive drum, the projection of the pressing component and the projection of the photosensitive drum do not coincide at all, and finally the drive unit 1080 and the power receiving unit 21 are successfully meshed. Throughout the process, the distance between the pressing component C40 and the axis of the photosensitive drum remains unchanged.

[0325] In some embodiments, after the drive unit 1080 rotates, the drive unit 1080 can be smoothly engaged with the power receiving unit 21.

[0326] Example 4

[0327] 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 (partial) and within the mounting space of the processing box 1 in the electronic imaging device (see reference). Figure 31 (The installation space of the processing box 1). Other parts not described herein can be referred to in the foregoing embodiments, and will not be repeated for the sake of simplicity.

[0328] like Figures 13 to 16b As shown, this embodiment provides another pressing component in the processing box. In this embodiment, the pressing component D40 is fixedly mounted on the processing box 1 or integrally formed with the processing box, and is located on the same side as the power receiving unit 21. In a plane perpendicular to the axis of the photosensitive drum, the projection of the pressing component D40 does not coincide with the projection of the photosensitive drum. Furthermore, the pressing component D40 includes a guiding pressing surface D40a1 (sloping or curved surface), which is located on the front end of the pressing component D40 (the mounting direction of the processing box 1) facing the power receiving unit 21. This guiding pressing surface D40a1 corresponds to the block protrusion D1010. The installation process of this embodiment is as follows:

[0329] 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. Under the action of the guiding pressing surface D40a1 and the block protrusion D1010, the pressing member D40 moves upward and forward. Since the pressing member D40 is fixedly set 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, so that the entire processing box 1 rotates in the counterclockwise direction (viewed from the axial direction of the power receiving unit 21).

[0330] like Figure 14b As shown, as the processing box 1 continues to be installed, the pressing member D40 moves upward past the block protrusion D1010 and then moves above the baffle 1081. At this time, the front end of the pressing member D40 is about to pass above the baffle 1081 and enter the opening position of the baffle 1081 to contact the drive unit 1080, as shown. Figure 15a As shown.

[0331] like Figure 15b As shown, after the processing box 1 is installed in the electronic imaging device, the pressing member D40 is located above the drive unit 1080. Viewed from the back of the processing box 1, one end 1A of the processing box 1, that is, the end where the power receiving unit 21 is located, is higher in the electronic imaging device than the other end 1B of the processing box 1 (the processing box 1 is partially upturned).

[0332] like Figure 16a , Figure 16b As shown, with the closing of the electronic imaging device door, the pressure rod D1020 on the inside of the door presses down on the upper surfaces 1C of the left and right sides of the back of the processing box 1, causing the processing box 1 to be subjected to force. The front end of the processing box 1 moves down and drives the pressing member D40 down. At this time, the front end of the pressing member D40 presses down on the driving unit 1080, causing it to move downwards to be basically coaxial with the power receiving unit 21 to receive the driving force. Since the power receiving unit 21 and the driving unit 1080 are coaxial, the lower rear part of the processing box 1 rotates clockwise. When the pressure rod D1020 applies pressure to the left and right sides of the processing box 1, the two ends (1A, 1B) of the processing box 1 remain basically horizontal.

[0333] In some embodiments, the processing box can also press down the front end of the pressing member D40 to drive unit 1080 under its own gravity, so that drive unit 1080 moves downward and is substantially coaxial with power receiving unit 21 to receive power.

[0334] Example 5

[0335] This embodiment is a further improvement on embodiment four. All parts not explicitly described are the same as those in embodiment four. Figures 17a-18 As shown, the processing box also includes a limiting guide E40b, an elastic element (not shown in the figure), and a guidance control component E40c. The limiting guide E40b is movably disposed on the end cover of the processing box 1 and is located at the same end of the box body as the power receiving unit 21, and the limiting guide E40b can be displaced axially on the photosensitive drum. Specifically, the limiting guide E40b can be a protrusion provided on the end cover of the processing box 1, for example, it can be a cylindrical structure. The elastic element is sleeved on the limiting guide E40b, and the two ends of the elastic element press against the limiting guide E40b and the inner wall of the end cover, respectively, and the elastic element applies a force pointing inward to the limiting guide E40b to the limiting guide E40b. When no other external force is applied, the limiting guide E40b is kept in a retracted state on the end cover, so that the end cover of the processing box 1 will not interfere with the inner wall of the electronic imaging device during the installation of the processing box.

[0336] The guidance control component E40c can be a rocker arm, which can be located inside the end cover of the processing box 1. The receiving part of the rocker arm is located at the rear of the processing box, and receives the signal from the pressure rod E1020 through the receiving part of the rocker arm. Figure 18 The force (described later) received by the external force is transmitted to the limiting guide E40b, for example, by means of inclined surface engagement, to push the limiting guide E40b out of the end cover and into an extended state. Similar to Embodiment 4, the pressing member E40 is fixedly mounted on the box body or integrally formed with the processing box, and when the processing box 1 is installed in the electronic imaging device, the pressing member E40 is located above the driving unit 1080.

[0337] Furthermore, as the cover of the electronic imaging device closes, the pressure bar E1020 inside the cover presses down on the upper surfaces 1C of the left and right sides of the back of the processing box 1, causing the processing box 1 to be subjected to force. The front end of the processing box 1 moves downward, causing the pressing member E40 to move downward as well. At this time, the front end of the pressing member E40 presses down on the drive unit 1080, causing the drive unit 1080 to move downward to a position substantially coaxial with the power receiving unit 21 to receive power. The pressing 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 pressing member E40 does not coincide with the projection of the photosensitive drum. Since the power receiving unit 21 and the drive unit 1080 are coaxial, the lower rear part of the processing box 1 rotates clockwise. With the pressure bar E1020 applying pressure to the left and right sides of the processing box 1, both ends (1A, 1B) of the processing box 1 remain substantially horizontal. Simultaneously, the pressure lever E1020 presses down on the guide control component E40c, causing it to move within the end cover along the direction of arrow R. This movement, through a beveled engagement, allows the limiting guide component E40b, which was originally retracted from the end cover, to extend from it (in the diagram, the limiting guide component E40b extends perpendicularly to the paper surface). At this point, since the processing cartridge is aligned, the extended limiting guide component E40b can engage with a limiting groove E1011 located in the electro-imaging device. This limits the installation of the processing cartridge, preventing it from wobbling and ensuring stable operation during printing.

[0338] When the processing box needs to be removed from the electro-imaging device, the door cover is opened, causing the pressure rod E1020 to rise. As the force applied to the guide control component E40c disappears, the elastic restoring force of the elastic element connected to the limiting guide component E40b causes the limiting guide component E40b to retract into the end cover. Simultaneously, the guide control component E40c returns to its pre-installation state. Preferably, the pressure rod E1020 first presses down on the upper surface 1C of the processing box 1 to align the processing box, and then the pressure rod E1020 applies force to the guide control component E40c, allowing the limiting guide component E40b to extend and engage with the limiting groove E1011. This process can be achieved by providing different stepped surfaces along the travel direction of the pressure rod E1020, for example, sequentially providing a first stepped surface E1021 and a second stepped surface E1022 along the travel direction (arrow M) of the pressure rod E1020. When the door cover is closed and the pressure rod E1020 is pressed into the device, the first stepped surface E1021 first presses against the upper surface 1C of the processing box, causing the processing box to align. Then, with further pressing of the pressure rod E1020, the second stepped surface E1022 begins to contact the force-bearing surface of the pressing guide control component E40c, thereby allowing the limiting guide component E40b to extend into the limiting groove E1011. Furthermore, the guide control component E40c is not limited to being located inside the end cover; it can also be located outside the processing box, without limitation.

[0339] Example 6

[0340] Based on Embodiment 2 or Embodiment 4, this embodiment provides another processing box structure. For example... Figure 19 and Figure 20 As shown, the processing box 1 includes a power receiving unit 21, a bracket F11, a pressing component F40, and a control mechanism F30. The power receiving unit 21 is movably disposed at one end of the box body and is used to receive the driving force of the electronic imaging device. The control mechanism F30 is used to control the displacement of the power receiving unit 21 along the axial direction of the photosensitive drum. The pressing component F40 is fixedly disposed on the box body or is integrally formed with the processing box and located at the same end as the power receiving unit 21. The pressing component F40 can press the drive unit 1080 (e.g., ...) Figure 15b As shown), the drive unit is positioned correctly. The pressing element F40 forces the drive unit 1080 from its initial tilted position to a position approximately parallel to the axis of the photosensitive drum. In a plane perpendicular to the axis of the photosensitive drum, the projection of the pressing element F40 does not coincide with the projection of the photosensitive drum. A bracket F11 is located at one end of the housing, and the bracket F11 has an elongated groove F110 and multiple mounting holes F113. The groove F110 has a first end F111 and a second end F112.

[0341] 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 multiple fixing holes F311 and ribs F312. One end of the pressing member F32 is provided with a connecting post F321, and the other end of the pressing member F32 is provided with a pressing part F323. The pressing part F323 has an inclined surface, and the middle part F322 of the pressing member F32 is a chamfered structure, so that there is a height displacement difference between the connecting post F321 and the pressing part F323 in the width direction of the pressing member F32.

[0342] 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 member F90. The power receiving unit 21 is provided with a meshing part F213 for engaging with the drive unit 1080 and a connecting hole F211. Between the meshing part F213 and the connecting hole F211, there is an abutment surface F212 extending outward along the axis of the power receiving unit 21. 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 disposed on the upper surface F53, and the protrusion F51 protrudes in a direction away from the upper surface F53 and has 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-apart support portions F61.

[0343] 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 disposed in the hub F60, so that the lower surface F54 of the movable part F50 abuts against the support part F61 of the hub F60; the power receiving unit 21 is installed into the movable part F50 through the through hole F52 of the movable part F50, at which time the abutment surface F212 of the power receiving unit 21 ( Figure 22 The power receiving unit 21 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 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 support part F61 built into the hub F60, so that the hub F60 can be rotated after the power receiving unit 21 receives the driving force from the drive unit 1080; the first elastic member F90 is disposed in the hub F60, and one end of the first elastic member F90 abuts against the bottom surface of the hub F60, and the other end of the first elastic member F90 abuts against the two ends of the connecting part F70.

[0344] The aforementioned components, when assembled together, can be uniformly mounted onto one end of the photosensitive drum 20. This allows the hub F60, upon receiving driving force, to rotate the photosensitive drum 20 and transmit the driving force through the gear section of the hub F60 to the developing roller gear 31, thereby rotating the developing roller 30. The bracket F11 covers the movable part F50, exposing the power receiving unit 21 and the protrusion F51 on the movable part F50 to the outside 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 installed in the 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 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 component F32 to the bracket F11, the fixing component F31 is installed into the groove F110 through the rib F312 and covers a part of the pressing component F32. Multiple screws (not shown in the figure) pass through multiple fixing holes F311 and multiple mounting holes F113 in sequence, thereby fixing the fixing component F31 and the bracket F11 to the box body to prevent the control mechanism F30 and the power receiving unit 21 from coming out of the processing box 1.

[0345] The following describes the process of contact engagement and disengagement between the power receiving unit of the processing box and the drive unit of the electronic imaging device (to facilitate understanding of the movement of the pressing component F32 in the bracket F11, the fixing component F31 in the control mechanism F30 is...). Figure 25 (Not shown in China).

[0346] 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 the extended state. The pressing part 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. This causes the movable member F50, together with the power receiving unit 21, to overcome the elastic force of the first elastic member F90 and be compressed in the bracket F11. The engaging part 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.

[0347] 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 baffle 1081. As the processing box 1 continues to be installed, the pressing member F40 is inserted into the opening of the baffle 1081 and contacts the drive unit 1080. As the front end of the processing box 1 moves down, it drives the pressing member F40 to move down. At this time, the front end of the pressing member F40 presses down on the drive unit 1080, causing the drive unit 1080 to move down to be basically coaxial with the power receiving unit 21 to receive power. Simultaneously, during the process of the pressing member F40 pressing down on the drive unit 1080, the pressing member F32, which abuts against the protrusion F51, moves to a position contacting the baffle 1081. As the processing box is installed, the pressing member F32, under the force of the baffle 1081, overcomes the elastic force of the second elastic member F80 and moves in the opposite direction to the installation direction X6. At this point, the pressing member F32 no longer abuts against the protrusion F51, and the movable member F50, having lost the force of the pressing member F32, drives the power receiving unit 21 to move along the Y6 direction (i.e., away from the inside of the photosensitive drum). At the same time, the lower surface F54 of the movable member F50 no longer contacts the support part F61 of the hub F60. At this time, the power receiving unit 21 is in the second position. After the processing box is 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 realizing the transmission of driving force.

[0348] like Figure 29 As shown, when the processing box is finished and needs to be removed from the electronic imaging device, the user can first pull out one end 1B of the processing box 1, so that one end 1B of the processing box is tilted relative to the other end 1A of the processing box 1 (i.e. 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 drive unit 1080. At this time, the pressing member F32 gradually moves along the X6 direction to the position where it abuts against the protrusion F51 again, so that the moving member F50 drives the power receiving unit 21 to move in the direction pointing towards the inside of the photosensitive drum 20. Finally, the power receiving unit 21 and the drive unit 1080 disengage, so that the processing box can be successfully removed from the electronic imaging device.

[0349] In some embodiments, the first end 1A of the processing box 1 is further provided with a guide surface F44, which is located behind the pressing member F40. The guide surface F44 can prevent interference with the block protrusion D1010 during the installation and removal of the processing box 1. Optionally, the guide surface F44 can be configured as an inclined surface or curved surface that slopes towards the rear of the processing box. During the installation and removal of the processing box, the block protrusion D1010 can slide against the surface of the guide surface F44, avoiding interference between the processing box and the block protrusion D1010, thereby preventing interference with the installation of the processing box.

[0350] In some embodiments, the first end 1A of the processing box 1 is further provided with a guided portion F41. Specifically, the guided portion F41 may protrude outward from the end face of the processing box so as to abut against the guide rail on the electronic imaging device during the installation of the processing box, thereby guiding the installation of the processing box. Optionally, the guided portion F41 may also be provided at other positions on the first end, as long as it can abut against the guide rail on the electronic imaging device and be guided. Of course, in some embodiments, the guided portion F41 may be omitted.

[0351] Example 7

[0352] Based on Embodiment Six, this embodiment provides another processing box.

[0353] like Figures 30 to 34 As shown, the processing box 1 includes a bracket G11, a photosensitive drum 20, a pressing component G40, a movable component G50, a support component G60, a power receiving unit G21, and an elastic component (not shown in the figure). It should be noted that the pressing component G40 in this embodiment has the same structure as the pressing component in embodiment six. The pressing component G40 is fixedly mounted on the box body and is located at the same end of the box body as the power receiving unit G21.

[0354] Specifically, the power receiving unit G21 includes a cylindrical body G212. One end of the body G212 is provided with a meshing part G211 that meshes with the drive unit 1080. A plurality of connecting posts G213 are evenly spaced on the circumferential surface of the body G212. The number of connecting posts G213 is not limited; in this embodiment, the number of connecting posts G213 is three. The outer circumference of the movable part G50 is provided with a gear portion. Specifically, the movable part G50 also has a limiting part G51, and one surface of the limiting part G51 has 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 that of the lower cylinder G64. The outer circumferential surface of the upper cylinder G63 is provided with a number of grooves G65 corresponding to the number of protrusions G52. The lower cylinder G64 is also provided with a support surface G61. The support surface G61 is provided with a number of outwardly protruding inclined surfaces G62 corresponding to the number of protrusions G52.

[0355] like Figure 36 and Figure 37As shown, the connection relationship of the above-mentioned parts is as follows: the movable part G50 is sleeved on the upper cylinder G63 of the support part G60 to be installed in the support part G60, the protrusion G52 is located on the support surface G61, and the movable part G50 can rotate and translate relative to the support part G60. The power receiving unit G21 passes through the movable part G50 and the support part G60, and the connecting post G213 passes through the groove G65. At the same time, the connecting post G213 is supported by the limiting part G51 of the movable part G50, thereby movably connecting the power receiving unit G21 to the support part G60, and the power receiving unit G21 can move together with the movable part G50. The elastic element (not shown in the figure) is disposed between the power receiving unit G21 and the support part G60, and one end of the elastic element abuts against the power receiving unit G21, and the other end abuts against the bottom surface inside the support part G60.

[0356] Furthermore, such as Figure 35 As shown, in order to enable the power receiving unit G21 to translate along the axial direction of the photosensitive drum 20, the processing box 1 also includes a control mechanism G30. The control mechanism G30 cooperates with the movable part G50 to control the rotation of the movable part G50, so that the power receiving unit G21 can generate displacement in the axial direction of the photosensitive drum 20. Specifically, the control mechanism G30 includes a connecting part G31, an intermediate gear G32, and a drive gear G80. The intermediate gear G32 is connected to the connecting part G31. In this embodiment, the intermediate gear G32 and the connecting part G31 are integrally formed. The drive gear G80 can be sleeved on the other end of the connecting part G31. Optionally, the drive gear G80 can also be a rubber wheel. When the control mechanism G30 is installed on the housing, the end of the connector G31 with the intermediate gear G32 is located close to the developing roller 30, and the intermediate gear G32 can mesh with the gear part of the movable part G50. By rotating the control mechanism G30, the movable part G50 and the power receiving unit G21 can be driven to move in a direction away from the inside of the photosensitive drum 20.

[0357] 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 inside the bracket G11, and the power receiving unit G21 and the movable part G50 are positioned close to the photosensitive drum 20. At this time, the power receiving unit G21 is in its initial position.

[0358] like Figures 38 to 39As shown, when the processing box 1 is installed into the electronic imaging device, the front end of the pressing member G40 abuts against the baffle 1081. As the processing box 1 continues to be installed, the pressing member G40 is inserted into the opening of the baffle 1081 and contacts the drive unit 1080. When the front end of the processing box 1 moves down and drives the pressing member G40, which is fixed relative to the processing box, to move down as well, the front end of the pressing member G40 presses down on the drive unit 1080, causing the drive unit 1080 to move downward to be substantially coaxial with the power receiving unit G21 to receive power. Furthermore, in a plane perpendicular to the axis of the photosensitive drum, the projection of the pressing member G40 does not coincide with the projection of the photosensitive drum at all. Simultaneously, during the process of the pressing member G40 pressing down on 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 section has a helical gear structure. The external gear section of the drive unit 1080 meshes with the drive gear G80, so that the drive gear G80 transmits the received driving force to the intermediate gear G32, and then the intermediate gear G32 transmits the driving force to the gear section of the movable member G50 that meshes with it, thereby driving the movable member G50 to rotate. As the movable member G50 rotates, the protrusion G52 moves to the position of abutting against the inclined surface G62, and moves from its lower position to its higher position along the inclined surface G62, so that the movable member G50 and the power receiving unit G21, which is fixedly connected to the movable member G50, 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, and finally the power receiving unit G21 successfully meshes with the drive unit 1080, realizing the transmission of driving force. Since 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 at the end of the photosensitive drum 20 away from the movable member G50, and a developing roller gear G26 is provided at the end of the developing roller 30 away from the movable member G50. The developing roller gear G26 meshes with the photosensitive drum gear G25, so that the movable member G50 can transmit the driving force received from the power receiving unit G21 to the photosensitive drum gear G25, and then to the developing roller gear G26 that meshes with the photosensitive drum gear G25, thereby driving the developing roller 30 to rotate.

[0359] In this embodiment, the method for removing the processing box from the electronic imaging device is similar to that in Embodiment Six. The relative tilting of the processing box during the removal process makes it easier for the user to remove the processing box from the electronic imaging device.

[0360] refer to Figure 37As shown, in some embodiments, an elastic reset member G27 is provided at the end of the power receiving unit G21 away from the engaging part G211. This elastic reset member G27 can be a compression spring. When the drive unit 1080 stops rotating, since the elastic force of the elastic reset member G27 is greater than the interaction force between the drive unit 1080 and the power receiving unit G21, the power receiving unit G21 can be pulled back to its initial position through the elastic reset member G27. With this structure, the processing box can be smoothly removed without tilting.

[0361] Example 8

[0362] The processing box 1 and the electronic imaging device in this embodiment are basically the same in shape and structure as the processing box and the electronic imaging device in embodiment four. The similarities will not be repeated here. Only the main differences will be introduced below.

[0363] like Figures 41a to 42 As shown, the electronic imaging device includes a main component H100, in which a processing box 1 is detachably housed. The main component H100 has a first sidewall H101 and a second sidewall H102 along the length Y direction of the processing box 1. Both the first sidewall H101 and the second sidewall H102 are provided with guide rails for guiding the installation of the processing box 1. Specifically, the second sidewall H102 has a first guide rail H103 and a second guide rail H104 for guiding the installation of the processing box 1. The first guide rail H103 includes a first guide segment H1031 and a second guide segment H1032, which are continuous. In the installation direction of the processing box 1 to the electronic imaging device, the second guide segment H1032 is located below the first guide segment H1031. In this embodiment, both the first guide segment H1031 and the second guide segment H1032 are inclined surfaces, and both are tilted rearwards in the direction of the processing box installation. In the normal operating state where the electronic imaging device is placed on a horizontal plane, the angle between the second guide segment H1032 and the horizontal plane is greater than the angle between the first guide segment H1031 and the horizontal plane. Optionally, the first guide segment H1031 and the second guide segment H1032 can also be constructed as curved surfaces, or one can be an inclined surface and the other a curved surface. Optionally, the first guide segment H1031 and the second guide segment H1032 can also be inclined guide grooves. In this embodiment, the rear half of the first guide rail H103 forms a recess, that is, the second guide segment H1032 is concave relative to the first guide segment H1031.

[0364] The second guide rail H104 is positioned close to the baffle 1081, and its downstream end extends to the upper side of the baffle 1081. In the installation direction of the processing box 1, the second guide rail H104 is located downstream of the first guide section H1031. Specifically, the second guide rail H104 includes a third guide section H1041, a fourth guide section H1042, and a fifth guide section H1043. Along the installation direction of the processing box 1, these three guide sections are arranged sequentially and are continuous. In this embodiment, the third guide segment H1041, the fourth guide segment H1042, and the fifth guide segment H1043 are constructed as inclined planes, 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 sequentially. The fourth guide segment H1042 and the fifth guide segment H1043 are set close to the baffle 1081.

[0365] A third guide rail H1012 for guiding the installation and positioning of the processing box 1 is provided on the first sidewall H101. In this embodiment, the third guide rail H1012 is composed of an inclined surface. Alternatively, the third guide rail H1012 may also be composed of a curved surface, or the third guide rail H1012 may also be a guide groove.

[0366] Furthermore, the electronic imaging device also includes a first identification mechanism and a second identification mechanism for preventing misinstallation of the processing cartridge 1. The first identification mechanism is disposed on the second sidewall H102 of the electronic imaging device and includes a first movable member H1033. The first movable member H1033 is movable between a first position that restricts the installation of the processing cartridge 1 and a second position that allows the installation of the processing cartridge 1. Specifically, the first movable member H1033 is supported on the second sidewall H102 of the main assembly. The first movable member H1033 is rotatable about an axis parallel to the installation direction X of the processing cartridge 1. In the first position, the first movable member H1033 protrudes from the second sidewall H102 to interfere with the processing cartridge 1 installed on the main assembly H100 and restrict the installation of the processing cartridge 1. In this position, the processing cartridge 1 is blocked by the first movable member H1033 and cannot be installed in place, thus preventing it from receiving driving force from the electronic imaging device. In the second position, the first movable component H1033 retracts relative to the first position, that is, it deflects closer to the second sidewall H102. In this position, the processing cartridge 1 can be installed in place so that it can receive driving force from the electro-imaging device and perform normal printing operations. "Installation in place" here means that the processing cartridge 1 can normally receive driving force and perform printing operations after installation. In this embodiment, the first movable component H1033 is a protrusion.

[0367] The second identification mechanism is located on the first sidewall H101 of the electronic imaging device. It is configured as a swing arm H1013 capable of swinging around a pivot parallel to the length direction Y of the processing box 1. A push-receiving part H1014 protruding along the length direction Y of the processing box is provided on the upper side of the swing arm H1013. In the installation direction of the processing box 1, the free end of the swing arm H1013 is located on the downstream side, and the end hinged to the pivot is located on the upstream side. That is, the swing arm is in an inclined state, and the swing arm H1013 can extend to the third guide rail H1012. During the installation of the processing box 1, the swing arm H1013 needs to be pushed to rotate in order to achieve the smooth installation of the processing box 1; otherwise, it will be impossible to install.

[0368] like Figures 43-45 As shown, the processing box 1 in this embodiment further includes a first guided portion H41 and a second guided portion H42. Both the first guided portion H41 and the second guided portion H42 are disposed at the first end 1A of the processing box 1 (the end where the power receiving unit is disposed). Specifically, the first guided portion H41 is disposed on the photosensitive drum frame and is located upstream of the photosensitive drum 20 in the installation direction of the processing box. In this embodiment, the first guided portion H41 is constructed as a protrusion that protrudes outward from one end of the processing box 1 along the length direction Y of the processing box 1, so as to abut against the first guide rail H103 in the early stage of the installation process to guide the installation of the processing box. Optionally, the first guided portion can also be the lower outer edge of the processing box housing. The second guided portion H42 can abut against the second guide rail H104 in the later stage of the installation process of the processing box 1. In this embodiment, the second guided portion H42 is located above the first guided portion H41 in the installed state of the processing box 1, and is located downstream of the first guided portion H41 in the installation direction of the processing box and is fixedly connected to the pressing member H40. Preferably, the second guided portion H42 is integrally formed with the pressing member H40, and in the installation direction of the processing box 1, the second guided portion H42 is located above the pressing member H40. Preferably, the second guided portion H42 is located on the upper outer periphery of the photosensitive drum 20. Preferably, the second guided portion H42 is constructed as a protrusion that protrudes outward from one end of the processing box 1 along the length direction of the processing box 1.

[0369] like Figure 44 As shown, the processing box 1 also includes a third guided portion H43, which is disposed at the second end 1B of the processing box 1 (the end opposite to the power receiving unit). The third guided portion H43 can abut against and cooperate with the third guide rail H1012 during the installation of the processing box 1. Preferably, in this embodiment, the third guided portion H43 is configured as a protrusion that protrudes outward from one end of the processing box 1 along the length direction of the processing box 1. More preferably, the third guided portion H43 is disposed at one end of the photosensitive drum 20 in the axial direction and is configured as a circular guide post. The third guided portion H43 may also be disposed on the end cover (not shown in the figure).

[0370] Furthermore, the processing box 1 also includes a first guide surface H44, which is disposed at the first end 1A of the processing box 1. The first guide surface H44 guides the first movable component H1033 to prevent interference between the processing box 1 and the first movable component H1033 during disassembly, ensuring that the first movable component H1033 can smoothly detach from the first guide surface H44. Overall, the first guide surface H44 is located on the upper side of the processing box 1. In the installation direction of the processing box 1, the first guide surface H44 is located upstream of the photosensitive drum 20 and upstream of the contact portion where the pressing member H40 and the drive unit 1080 abut against each other. In this embodiment, the first guide surface H44 is configured to face forward and upward, and can also be configured as a curved surface. When the processing box 1 is installed in the electronic imaging device, the first guide surface H44 can be pressed by the first movable component H1033 to restrict the rotation of the processing box 1 and to position it. In this case, the first guide surface H44 can also be configured as a non-inclined surface structure. Compared with a non-inclined surface structure, the inclined first guide surface H44 can avoid interference between the processing box 1 and the first movable component H1033 during installation and removal, thus avoiding affecting the installation and removal operations of the processing box 1.

[0371] To prevent interference between the pressing member H40 and the baffle 1081 during disassembly of the processing box 1, the pressing member H40 also includes a guiding pressing surface H45. The guiding pressing surface H45 is located on the lower side of the pressing member H40. By providing the guiding pressing surface H45, interference between the pressing member H40 and the baffle 1081 during disassembly of the processing box 1 can be avoided, thus preventing interference with the disassembly of the processing box 1. When the processing box 1 is installed in the electronic imaging device, the pressing member H40 extends into the baffle 1081 and presses against the drive unit 1080, causing the drive unit 1080 to move from its initial tilted position to a position where it intersects with the support member 1085 (e.g., ...). Figure 2 The positions where the axes of the pressure member coincide (as shown). Furthermore, on a plane perpendicular to the axis of the photosensitive drum, the projection of the pressure member is outside the projection range of the photosensitive drum. The guiding pressure surface H45 on the pressure member H40 abuts against the outer wall of the baffle 1081. Specifically, since the pressure member H40 extends into the opening 10813 located on the upper side of the baffle 1081, the guiding pressure surface H45 presses against the outer edge 10814 of the opening 10813.

[0372] 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 are higher than the upper surface of the processing box. The first pressing surface H46 is used to unlock the swing arm H1013 during the installation of the processing box, and the second pressing surface H47 is used to unlock the swing arm H1013 during the removal of the processing box 1 from the electronic imaging device. In the installation and removal direction of the processing box 1, the second pressing surface H47 and the first pressing surface H46 are stepped, i.e., they have a height difference, with the second pressing surface H47 located above the first pressing surface H46. In this embodiment, the first pressing surface H46 and the second pressing surface H47 are constructed as curved surfaces or inclined surfaces. Specifically, both the first pressing surface H46 and the second pressing surface H47 are inclined towards the rear in 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, where H1 is 3.37mm and H2 is 10.05mm; preferably, the height difference H3 between the first pressing surface H46 and the surface where the pendulum arm H1013 engages is preferably less than 2.72mm, and the height difference H4 between the second pressing surface H47 and the surface where the pendulum arm H1013 engages is preferably less than 4.06mm. Within these ranges, the coordination effect with the pendulum arm is better.

[0373] Next, combine Figures 42-49 This document details the specific operation process of installing the processing box 1 into the electronic imaging device, as well as the coordination process of each component.

[0374] During the installation of the processing box, the stage before the second guided part H42 is supported by the second guide rail H104 is called the early stage (or pre-installation stage) of the installation process of processing box 1, and the stage when the second guided part H42 is supported by the second guide rail H104 is called the late stage (or post-installation stage) of the installation process of processing box 1.

[0375] During the initial installation of the processing box, the user holds the handle of processing box 1 (not shown in the figure) and places it into the electronic imaging device, causing the first guided part H41 and the third guided part H43 to embed into the first guide rail H103 and the third guide rail H1012 respectively, and pushes the processing box 1 along the installation direction of processing box 1. At this time, the first guided part H41 of processing box 1 can abut against the first guide section H1031 of the first guide rail H103, and the third guided part H43 abuts against the third guide rail H1012, that is, the processing box is supported by the first guide section H1031 of the first guide rail H103 and the third guide rail H1012. As the processing box 1 moves along the guide rail towards the front edge of the processing box in the X direction (e.g., ... Figure 41bAs shown, the first guided part H41 moves forward. When the first guided part 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 part H42 abuts against the third guide segment H1041 of the second guide rail H104, and the first guided part H41 also disengages from the first guide rail H103, and the first end 1A of the processing box is lifted.

[0376] During the later stages of the processing box installation, the second guided part H42 abuts against the third guided section H1041, and the third guided part H43 abuts against the third guide rail H1012. The processing box 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 X direction (the installation direction of the processing box), the second guided part H42 abuts against the third guide section H1041 and enters the fourth guide section H1042. During the movement of the second guided part H42 abutting against the fourth guide section H1042, the processing box 1 rotates in the W direction with the abutment point between the second guided part H42 and the fourth guide section H1042 and the abutment point between the third guided part H43 and the third guide rail H1012 as fulcrums. That is, the processing box 1 moves forward while rotating along the guide rail, and the pressing member H40 is lifted in the W direction. This movement mode can avoid interference between the pressing member H40 and the baffle 1081. During this process, the processing box can move forward under the action of external force or under its own gravity.

[0377] As the processing box 1 continues to move forward along its installation direction (X direction), the second guided part H42 eventually disengages from the second guide rail H104 at the fifth guide section H1043. The pressing member H40 extends into the opening 10813 above the baffle 1081 to press the drive unit 1080, and the guiding pressing surface H45 presses against the outer edge 10814 of the opening 10813. At this point, the installation of the processing box 1 is complete. The first movable part H1033 presses against the first guide surface H44 to suppress the rotation of the processing box 1, making the state of the processing box 1 more stable. During this process, the processing box can move forward under the action of external force or under its own gravity.

[0378] Combine Figures 43-45 During the installation of the processing box 1, the first end 1A of the processing box 1 has a hollowed-out clearance part H48, which prevents interference with the first movable part H1033 during installation. During the installation of the processing box 1, the first pressing surface H46 of the second end 1B of the processing box 1 first contacts the pushed part H1014 on the upper side of the swing rod H1013, and pushes the swing rod H1013 to rotate, thereby preventing the third guided part H43 from being blocked by the free end of the swing rod H1013.

[0379] When disassembling the processing box 1, the user holds the handle of the processing box 1 and removes it from the electronic imaging device in the opposite direction to the X direction of the processing box installation. It should be noted that in the early stage of disassembling the processing box 1, the second guided part H42 abuts against the second guide rail H104 and moves along the second guide rail H104. In the later stage of disassembly, it is supported by the first guided part H41 of the processing box 1, that is, the second guided part H42 abuts against the first guide rail H103 and moves along the first guide rail H103, while the third guided part H43 is always supported by the third guide rail H1012.

[0380] Combine Figures 49-50 During the disassembly of the treatment box, especially when the user first pulls out the treatment box, the first guide surface H44 is pressed by the first movable part H1033, which suppresses the rotation of the treatment box 1 in the opposite direction of the W direction. This reduces the depth of the pressing part H40 embedded in the opening 10813, thereby reducing or avoiding interference between the pressing part H40 and the baffle 1081 when it is taken out. Furthermore, since the pressing part H40 is provided with a guiding pressing surface H45, the disassembly of the treatment box 1 is made smoother.

[0381] When the second guided part H42 abuts against the fourth guide section H1042, the pressing member H40 has retracted from the opening 10813. Under the action of external force, the processing box can rotate in the opposite direction of W to a preset angle. The second pressing surface H47 of the processing box 1 first touches the pushed part H1014 of the swing rod H1013 and pushes the swing rod H1013 to rotate, thereby avoiding the third guided part H43 being blocked by the free end of the swing rod H1013 during the disassembly of the processing box 1 from the electronic imaging device.

[0382] Example 9

[0383] The processing box and electronic imaging device in this embodiment are basically the same in shape and structure as those in embodiment eight. The parts already described in embodiment eight will not be repeated here. The following only describes the differences from embodiment eight.

[0384] like Figure 52a As shown in the example of the electronic imaging apparatus in this embodiment, a fourth guide rail I105 is provided on the second sidewall I102 of the main component I100 of the electronic imaging apparatus. Preferably, the fourth guide rail I105 is at least partially located below the second guide rail I104 and is closer to the first sidewall I101 of the main component I100 along the Y direction relative to the second guide rail I104. In the mounting direction of the processing box, the fourth guide rail I105 is at least partially located upstream of the second guide rail I104. In this embodiment, the fourth guide rail I105 is inclined towards the rear side of the main component I100, and the fourth guide rail I105 can be constructed as an inclined surface, a curved surface, or a guide groove.

[0385] like Figure 52b As shown, a third guide rail I1012 for guiding the installation and positioning of the processing box 1 is provided on the first sidewall I101. In this embodiment, the third guide rail I1012 is composed of an inclined surface; alternatively, the third guide rail I1012 may also be composed of a curved surface or a guide groove. Preferably, the third guide rail I1012 includes a sixth guide segment I1015 and a seventh guide segment I1016, which are positioned in the installation direction of the processing box 1 (X direction, e.g., ...). Figure 41b As shown, the seventh guide segment I1016 is located downstream of the sixth guide segment I1015. Preferably, the seventh guide segment I1016 is parallel to the bottom surface of the main component I100, and the sixth guide segment I1015 is connected to the seventh guide segment I1016 and inclined to the rear side of the main component I100.

[0386] like Figure 53 As shown, this embodiment, compared to Embodiment 8, does not include a first guided portion. The processing box in this embodiment further includes a fourth guided portion I41, which is located on the lower side of the processing box 1 (downstream of the processing box 1 when it is installed in the electro-imaging device) and at the first end 1A of the processing box. Preferably, the fourth guided portion I41 is located on the end cap 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 electro-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 located 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 installation.

[0387] Similar to Embodiment 8, the second end 1B of the processing box 1 in this embodiment is also provided with a first pressing surface 146 for unlocking the swing arm 11013 (second identification mechanism) during installation and a second pressing surface 147 for unlocking the swing arm 11013 during disassembly 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 disassembly of the processing box, the second pressing surface 147 and the first pressing surface 146 are stepped, that is, they have a height difference, with the second pressing surface 147 located above the first pressing surface 146. In this embodiment, the first pressing surface 146 and the second pressing surface 147 are constructed as curved surfaces or inclined surfaces. Specifically, the first pressing surface 146 and the second pressing surface 147 are inclined in the opposite direction to the installation direction (X direction) of the processing box.

[0388] In some possible embodiments, in this embodiment, the processing box 1 further includes a limiting part I471. The limiting part I471 can limit the position of the processing box 1 when disassembling the processing box, so as to avoid excessive rotation of the processing box 1 and thus make the disassembly of the processing box difficult. For example, in some embodiments, the processing box will rotate as a whole during the removal process, and if the rotation of the processing box 1 exceeds a certain range, it will affect the removal effect. Therefore, it is necessary to limit the movement of the processing box 1 during the removal process to prevent the processing box from rotating too much. Preferably, since the limiting part I471 is provided on the second pressing surface I47, the limiting part I471 is limited by the swing rod I1013 when the processing box rotates, thereby limiting the rotation of the processing box.

[0389] Next, combine Figures 52a to 59b This document details the specific procedures for removing or installing the processing box 1 from the electronic imaging device, as well as the coordination process between each component and the electronic imaging device.

[0390] During the installation of the processing box 1, the stage before the second guided part I42 is supported by the second guide rail I104 is called the early stage (or the pre-installation stage) of the installation process of the processing box 1, and the stage when the second guided part I42 is supported by the second guide rail I104 is called the late stage (or the post-installation stage) of the installation process of the processing box 1.

[0391] Before installing the processing box 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 embed into the positions of the fourth guide rail I105 and the third guide rail I1012 respectively, and pushes the processing box 1 along the installation direction (X direction). At this time, the fourth guided part I41 of the processing box 1 can abut against the surface of the fourth guide rail I105, the second guided part I42 does not abut against the second guide rail I104, and the third guided part I43 can abut against the surface of the sixth guide segment 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 by the second guide rail I104. During this period, in some possible embodiments, the swing arm I1013 is also unlocked so that the processing box can be installed accurately; that is, the first pressing surface I46 first contacts the swing arm I1013 and pushes the swing arm I1013 to swing from the locked position to the unlocked position, so as to avoid the third guided part I43 from contacting the swing arm I1013 and causing installation interference.

[0392] As processing box 1 continues to move forward along the guide rail in the X direction (processor box mounting direction), refer to Figure 56As shown, the second guided part I42 abuts against the second guide rail I104, and the fourth guided part I41 disengages from the fourth guide rail I105. During the later stages of installation, the second guided part I42 abuts against the third guide section I1041, and the third guided part I43 abuts against the surface of the third guide rail I1012 (specifically, it could abut against the surface of the sixth guide section I1015). The processing box 1 is supported by the second guide rail I104 and the third guide rail I1012. As the processing box 1 moves forward, the second guided part I42 can abut against the third guide section I1041 and enter the fourth guide section I1042. Preferably, during the movement of the second guided part I42 abutting against the fourth guided section I1042, the processing box 1 can rotate in the W direction with the contact point between the second guided part I42 and the fourth guided section I1042 and the contact point between the third guided part I43 and the third guide rail I1012 as fulcrums. That is, the processing box 1 moves forward while rotating along the guide rail, and the pressing member I40 is lifted in the W direction. This movement mode can avoid the pressing member I40 interfering with the baffle 1081 in the forward direction. During this process, the processing box 1 can move forward under the action of external force or under its own gravity and rotate.

[0393] refer to Figure 41b As shown, in some possible embodiments, as the processing box 1 continues to move forward in the processing box mounting direction X, the second guided part I42 eventually disengages from the second guide rail I104 at the fifth guide segment I1043, and the pressing member I40 extends into the opening 10813 above the baffle 1081 (e.g., Figure 41b In the pressure drive unit 1080 (as shown), the second guide surface I45 presses against the outer edge 10814 of the opening 10813 (as shown). Figure 41b At the point shown, the processing box 1 is now fully installed. The first movable part I1033 presses against the first guide surface I44 to suppress the rotation of the processing box 1, making the processing box 1 more stable. During this process, the processing box 1 can move forward under the action of an external force or under its own gravity.

[0394] In some possible embodiments, the second guided portion I42 of the processing box can rotate in the W direction when it abuts against the third guide segment I1041 or the fifth guide segment I1043, so as to avoid interference and ensure that the processing box is installed smoothly.

[0395] In some possible embodiments, the installation process of the processing box 1 further includes a final installation stage. In this embodiment, the installation process after the second guided part I42 of the processing box 1 is detached from the second guide rail I104 is referred to as the final installation stage (or the final installation section). During the final installation stage, refer to... Figure 57As shown, the second guided part I42 disengages from the second guide rail I104, the free end of the pressing member I40 presses against the upper side of the baffle 1081, and the first end 1A of the processing box 1 is raised by a preset distance (e.g., Figure 58 (As shown); as the processing box 1 moves forward, the pressing member I40 extends into the opening 10813 above the baffle 1081, pressing the drive unit 1080. The first end 1A of the processing box also sinks downward as a whole, and can force the drive unit 1080 to rotate to a position coinciding with the axis of the baffle 1081 when the door cover of the imaging device is closed. At this time, the power receiving unit provided on the processing box 1 engages with the drive unit 1080. Moreover, on the plane perpendicular to the axis of the photosensitive drum, the projection of the pressing member is located outside the projection range of the photosensitive drum.

[0396] The disassembly process of the processing box and the coordination process of each component are the same as the assembly process of the processing box. This structural design makes the disassembly and assembly of the processing box smoother.

[0397] Specifically, when disassembling the processing box 1, the user holds the handle of the processing box 1 and removes it from the electronic imaging device in the opposite direction to the X direction of the processing box installation. In the early stages of disassembling the processing box 1, the rear of the processing box can be raised during the initial pulling motion to rotate the processing box by a preset angle, thereby reducing interference. As the processing box moves, the second guided part I42 abuts against the second guide rail I104 and moves along the second guide rail I104. In some possible embodiments, the second pressing surface I47 first contacts the pushed part I1014 of the swing arm I1013 and pushes the swing arm I1013 from the locked position to the unlocked position, preventing the third guided part I43 from contacting the swing arm I1013 and thus avoiding interference during box removal.

[0398] During the later stages of disassembly, the fourth guided part I41 of the processing box 1 is supported, that is, the fourth guided part I41 abuts against the fourth guide rail I105 and moves along the fourth guide rail I105, while the third guided part I43 is always supported by the third guide rail I1012.

[0399] In some possible embodiments, the processing box may rotate during removal, caused by factors such as the direction of the user's pulling force or the special structural design of the processing box. Figure 59a and Figure 59b As shown, during the movement of the third guided part I43 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 swing rod I1013 and pushes the swing rod I1013 to swing upward to unlock the swing rod I1013.

[0400] As the processing box moves in the opposite direction to its mounting direction (X direction), it can rotate a preset angle along the W2 direction. The limiting part I471 abuts against the pushing part I1014 of the swing arm I1013, causing the swing arm I1013 to swing upwards to its upper limit position (for example, in some embodiments, the swing arm I1013 contacts the side wall of the electronic imaging device or other limiting components at the upper limit position, thus preventing it from continuing to swing). Because the limiting part I471 abuts against the pushing part I1014 of the swing arm I1013, the processing box cannot continue to rotate, making the disassembly of the processing box smoother. In some embodiments, the limiting part I471 prevents the processing box from rotating excessively at the preset position, thereby preventing interference between the pressing member I40 and the baffle or the side wall of the electronic imaging device.

[0401] In some possible embodiments, the limiting part I471 abuts against the pushed part I1014 of the swing arm I1013 and puts the swing arm I1013 in the upper limit position, that is, when the third guided part I43 is located in the sixth guide segment I1015, or when the third guided part I43 is located at the intersection of the sixth guide segment I1015 and the seventh guide segment I1016, or when the third guided part I43 is located in the seventh guide segment I1016.

[0402] In some possible embodiments, during the installation or removal of the processing box 1, the fourth guided part I41 may be supported by the fourth guide rail I105 and the second guided part I42 may be supported by the second guide rail I104 at the same time, for example, during the transition between the early and late stages of installation.

[0403] In some possible embodiments, during the installation or removal of the processing box 1, the second guided part I42 may be supported by the second guide rail I104 and the pressing member I40 may be supported by the baffle 1081 at the same time, for example, during the transition between the later stage and the end stage of installation.

[0404] In some possible embodiments, during the initial stage of processing box installation, 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 segment 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 installation, thereby avoiding interference with some structures in the electronic imaging device, making the installation of the processing box smoother.

[0405] Example 10

[0406] This embodiment is an improvement based on Embodiments 8 and 9. The similarities will not be repeated here. The main differences are introduced below.

[0407] 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 sidewall I101 and the second sidewall I102 of the main component I100 of the electronic imaging device and is constructed as an inclined surface. Alternatively, it can be a curved surface or a guide groove.

[0408] Based on the processing box provided in Embodiments 8 and 9, the processing box in this embodiment further includes a fifth guided part K41 that cooperates with the fifth guide rail K1017, while the first guided part is eliminated. Figure 60 As shown, the fifth guided part K41 is disposed 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 installation or removal of the processing box. Preferably, the fifth guided part K41 is disposed in the middle of the processing box, biased towards the second end 1B. Alternatively, the fifth guided part K41 can also be disposed in the middle or at the first end 1A, as long as it can cooperate with the fifth guide rail K1017. The installation or removal process of the processing box in this embodiment is basically the same as that in embodiments eight and nine. The main difference is that in the early stage of installation of the processing box 1 in this embodiment, the processing box is supported by the fifth guide rail K1017, that is, the fifth guided part K41 cooperates with the fifth guide rail K1017.

[0409] In some possible embodiments, reference Figure 60 As shown, the processing box can simultaneously retain the fourth guided part I41 and the fifth guided part K41. 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 part I41 can abut against the fourth guide rail I105, and the fifth guided part K41 can abut against the fifth guide rail K1017.

[0410] Example 11

[0411] This embodiment is an improvement based on the foregoing embodiment. The similarities will not be repeated here. The main differences are described below.

[0412] In this embodiment, the unlocking member L47 is configured to be movable relative to the housing, thereby increasing the flexibility of the processing housing during installation and / or removal from the electronic imaging device and reducing the possibility of interference during installation and removal of the processing housing.

[0413] Specifically, such as Figure 61As shown, in this embodiment, the processing box further includes an elastic member L47b, which is disposed between the photosensitive drum frame 12 and the unlocking member L47. The unlocking member L47 and the photosensitive drum frame 12 have a predetermined movable space, allowing the unlocking member L47 to move in the L direction and the opposite direction. Preferably, the elastic member L47b can 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 swing arm I1013 to unlock, the unlocking member L47 can move against the elastic force of the elastic member L47b.

[0414] In some possible implementations, during the installation of the processing cartridge to or removal from the electronic imaging device, the unlocking component L47 and the lever I1013 (e.g.) are engaged. Figure 59c As shown, after touching and unlocking the lever I1013, it can always remain in contact with the lever I1013, that is, even when the processing box is installed in place, the unlocking component L47 is still in contact with the lever I1013.

[0415] In some possible implementations, with the processing box installed in place, the unlocking component L47 remains in contact with the lever I1013, keeping the lever I1013 in the unlocked position.

[0416] Example 12

[0417] This embodiment is a further improvement based on the foregoing embodiment. The similarities will not be repeated. The following mainly introduces the improvements.

[0418] like Figure 62 As shown, the processing box includes a photosensitive drum 20 and a charging roller M20a, which are rotatably supported on the photosensitive drum frame. Figure 62 The projection of the processing box 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 is taken as Q1, the rotation center of the charging roller M20a is taken as Q2, the straight line passing through Q1 and Q2 is taken as a1, and the straight line passing through Q1 and perpendicular to the straight line a1 is taken as a2. The vertical distance from a point on the first pressing surface M46 to the straight line a1 is taken as S1, the vertical distance from a point on the second pressing surface M47 to the straight line a1 is taken as S2, the horizontal distance from a point on the first pressing surface M46 to the straight line a2 is taken as S3, and the horizontal distance from a point on the second pressing surface M47 to the straight line a2 is taken as S4. Generally, if S1, S2, S3, and S4 are too large or too small, it will affect the installation and disassembly of the processing box and its cooperation with the swing arm I1013.

[0419] To facilitate smoother installation of the processing box and to ensure better fit between the first pressing surface M46 and the second pressing surface M47 and the swing rod I1013, preferably, 20mm≤S1≤35mm, 20mm≤S2≤40mm, 5mm≤S3≤35mm, and 40mm≤S4≤80mm.

[0420] Furthermore, the above technical solution is further optimized. If the values ​​of S1 and S3 are 25mm≤S1≤27mm and 18mm≤S3≤32mm respectively, S1 and S3 that meet the above value requirements can ensure smoother installation of the processing box and better cooperation between the first pressing surface M46 and the swing rod I1013.

[0421] The following are examples. Figure 63 The combination of the minimum values ​​of S1 and S3 is shown. This structural design makes the installation of the processing box smoother, and the cooperation between the first pressing surface M46 and the swing rod I1013 is better.

[0422] When the minimum value of S2 is 29mm≤S2≤37.5mm and the minimum value of S4 is 52mm≤S4≤80mm, the processing box is removed from the electronic imaging device more smoothly, and the cooperation between the second pressing surface M47 and the swing rod I1013 is better.

[0423] The following are examples. Figure 64 The combination of the minimum values ​​of S2 and S4 is shown. This structural design makes the processing box easier to install, and the first pressing surface 47 and the swing rod I1013 cooperate better.

[0424] This embodiment is a further improvement based on the foregoing embodiment. The similarities will not be repeated. The following mainly introduces the improvements.

[0425] like Figure 65 As shown, the processing box includes a photosensitive drum 20 and a charging roller M20a. Figure 65 The projection of the processing box 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 taken as Q1, the rotation center of the charging roller M20a is taken as Q2, the straight line passing through Q1 and Q2 is taken as a1, and the straight line passing through Q1 and perpendicular to the straight line a1 is taken as a2. The vertical distance from the free end of the pressing member M40 to the straight line a1 is taken as S5, and the vertical distance from the free end of the pressing member M40 to the straight line a2 is taken as S6.

[0426] To ensure smoother cartridge loading and unloading and to prevent interference between the pressure component and the baffle 1081, an excessively small / large S5 and / or an excessively large / small S6 will both hinder cartridge loading / unloading and result in poor coordination with the drive unit 1080. For example, in some embodiments, an excessively large S5 and / or an excessively small S6 may prevent effective pressure on the drive unit 1080, i.e., it may not be able to properly align the drive unit 1080. In some embodiments, an excessively small S5 and / or an excessively large S6 may cause interference with the printer during cartridge loading or unloading.

[0427] After research and testing, it was found that when the thickness is 8mm≤S5≤15mm and 4mm≤S6≤12mm, the processing box is more smoothly installed into or removed from the electronic imaging device, and can effectively compress the drive unit 1080.

[0428] For example, such as Figure 66 When the selected values ​​of S5 and S6 are combined as shown, the processing box is installed more smoothly, and the cooperation between the pressing component M40 and the drive unit 1080 is better.

[0429] Example 13

[0430] This embodiment provides a method for installing the above-mentioned processing box to an electronic imaging device and removing the processing box from the electronic imaging device, based on the foregoing embodiments.

[0431] The following describes the method for installing the processing box onto and removing it from the electronic imaging device. The installation method for the processing box includes the following specific steps:

[0432] Step A1: Open the door of the electronic imaging device.

[0433] Step A2: Insert the processing box into the main component of the electronic imaging device along the installation direction.

[0434] Step A3: When the treatment box is moved to the later stage of installation, the treatment box rotates in the W direction under the action of external force.

[0435] The method for removing the processing cartridge from the electronic imaging device includes the following specific steps:

[0436] Step B1: Open the cover of the electronic imaging device.

[0437] Step B2: Pull the processing box in the opposite direction of installation. Under the action of external force, the processing box rotates by a preset angle in the opposite direction of W.

[0438] Step B3: Continue pulling the processing box until it is completely detached from the electronic imaging device.

[0439] The above steps make the installation and removal of the processing box smoother and avoid unnecessary interference.

[0440] Example 14

[0441] like Figures 67 to 69 As shown, there is an existing electronic imaging device 100, in which a processing box 1 can be detachably housed. The electronic imaging device 100 includes a main component N101 for housing the processing box 1, a drive unit 1080, an openable and closable door cover 102, a connecting rod 103 that is linked to the door cover 102, and a cylindrical cam N104 connected to the connecting rod 103.

[0442] The main component N101 is provided with a receiving portion N105 for accommodating the processing box 1. The receiving portion N105 is provided with a first sidewall N106 and a second sidewall N107 along the length direction of the processing box 1. The first sidewall N106 and the second sidewall N107 are respectively provided with guide rails N108 for guiding the installation or removal of the processing box 1. The drive unit 1080 is provided on the second sidewall N107 of the receiving portion N105 for transmitting driving force to the processing box 1.

[0443] In this embodiment, the drive unit 1080 is generally composed of three cylindrical bodies of different diameters and sizes. The drive transmission part N1082 of the drive unit 1080 is disposed on the smallest diameter cylindrical body N1083 closest to the receiving part N105, and the drive transmission part N1082 can extend outward from or retract from the second side wall N107 of the receiving part N105. The door cover 102 is rotatably disposed on the main assembly N101 so as to open or close the receiving part N105.

[0444] Linkage 103, cam N104, and drive unit 1080 are located on the same side of receiving portion N105, and linkage 103, cam N104, and door cover 102 are linked together to lock or unlock drive unit 1080 when door cover 102 performs a closing or opening action. When drive unit 1080 is locked, drive unit 1080 cannot move and is in an inclined state. Drive transmission portion N1082 is in a retracted position relative to the second side wall N107 of receiving portion N105. This position can prevent drive transmission portion N1082 from interfering with power receiving portion N211 of processing box 1. When drive unit 1080 is unlocked, drive unit 1080 can move under the action of external force. That is, drive unit 1080 can change from an inclined position to a straight position (i.e., a non-inclined state) under the action of external force and can extend from the second side wall N107 to stably transmit driving force to processing box 1.

[0445] like Figures 70 to 72As shown, the processing 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 rotatably connected 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 on the front side of the processing cartridge 1 along the installation direction, facing each other to perform developing and other operations. 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 disposed at the first end N50 of the housing N10, and the power receiving unit N21 includes a power receiving part N211. The power receiving part N211 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.

[0446] Furthermore, in order to change the drive unit 1080 from its initial tilted state (in which the rotation axis NL1 of the drive unit 1080 is tilted relative to the rotation axis NL2 of the photosensitive drum 20) to an aligned state capable of engaging with the power receiving unit N21 (in which the rotation axis of the drive unit 1080 coincides with the rotation axis of the photosensitive drum 20), as... Figures 70 to 73 As shown, the processing box 1 also includes a pressing member N40, which is disposed at the first end N50 and is used to apply force to the driving unit 1080 to keep the driving unit 1080 in an upright position. During the installation of the processing box 1 into the electronic imaging device, the distance between the pressing member N40 and the axis of the photosensitive drum does not change. Specifically, the pressing member N40 is fixedly mounted on the end cover N202, thereby forming a fixed connection with the drum frame 12.

[0447] 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, with one mounting protrusion N401 located above the other mounting protrusion N401. The end cap N202 is provided with a mounting hole, which corresponds to the mounting protrusion N401. During assembly, the mounting protrusion N401 engages with the mounting hole, thereby fixing the pressing member N40 to the end cap N202 or the drum frame 12, and thus allowing the pressing member N40 to move with the movement of the drum frame 12.

[0448] On the rotation axis direction NL2 of the photosensitive drum 20, the pressing member N40 is located outside the end of the power receiving part N211 so that it can cooperate with the drive unit 1080 during the installation of the processing box. Further, 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 coincides with the projection of the photosensitive drum 20. That is, at least a portion of the pressing member N40 is located within the projected cross-section of the photosensitive drum 20. Alternatively, in other embodiments, the end cap can be omitted, and the pressing member N40 can be directly mounted on the drum frame 12, as long as the distance between the pressing member N40 and the rotation axis of the photosensitive drum 20 remains unchanged in the radial direction. Alternatively, the position of the pressing member N40 in the radial direction of the photosensitive drum 20 can be set on the outer side of the outer circumference of the photosensitive drum 20 or on the inner side of the photosensitive drum 20, as long as it can cooperate with the drive unit 1080.

[0449] Furthermore, the processing box 1 also includes a guide protrusion N704 and a guided portion N70 movable relative to the drum frame 12. The guided portion N70 is disposed on the end cap N202 of the first end N50, and the guided portion N70 cooperates with the 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 face of the end cap N202. The first protrusion N701 can be inserted into the guide rail N108 on the second side wall N107 of the receiving portion N105 when the processing box 1 is installed to the receiving portion N105, so as to guide the installation of the processing box 1. The guide protrusion N704 is disposed at the end of the box body N10 away from the guided portion N70, and the guide protrusion N704 cooperates with the guide rail N108 of the first side wall N106, so as to guide the installation of the processing box 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.

[0450] like Figure 73As shown, a groove N80 is provided on the end face of the end cap N202. Guide grooves N801 are respectively provided on the front and rear sidewalls of the groove N80, which are positioned opposite each other along the mounting 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, allowing the guided portion N70 to move relative to the drum frame 12 in the first direction. That is, the drum frame 12 or the entire cartridge body N10 of the processing cartridge 1 can move relative to the guided portion N70 in the first direction. In other embodiments, the guide groove N801 may also be provided on the guided portion N70, and the second protrusion N702 that cooperates with the guide groove N801 may be provided on the drum frame 12. Optionally, the guided portion N70 may also be fixedly connected to the developing frame 11. The first direction is the direction that intersects the rotation axis NL2 of the photosensitive drum 20 and the mounting direction NY1 of the processing box 1.

[0451] To facilitate the interaction between the guided part N70 and the guide rail N108, or to facilitate the installation of the processing box 1, the guided part N70 also includes an elastic element. In this embodiment, the elastic element is a compression spring N90, and there are two compression springs N90. The first protrusion N701 has spring mounting portions N703 on both sides of its moving direction relative to the drum frame 12. 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 portion N703 of the guided portion 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 held 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 its moving direction relative to the drum frame 12 or the developing frame 11, so that when the processing cartridge 1 is installed into the receiving portion 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 element can be omitted or only one elastic element can be used, which also allows the first protrusion N701 to move relative to the drum frame 12 or the developing frame 11, or in other words, to move relative to the entire processing cartridge 1. Alternatively, multiple guided parts N70 can be provided, or the same guided part N70 can be provided at the other end of the processing cartridge 1, so that both ends of the processing cartridge can move relative to the guide rail N108.

[0452] The following combination Figures 67 to 69 , Figure 75 and Figure 76 The installation process of processing box 1 is described.

[0453] When the processing box 1 is installed into 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 receiving part 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 part N70 in a direction that intersects 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 outer circumferential surface of the small-diameter cylindrical body N1083 of the drive unit 1080, the drive unit 1080 is locked because the door cover 102 is not closed. The pressing member N40 presses against the outer circumferential surface of the small-diameter cylindrical body N1083, and the first end N50 of the developing cartridge 1 is raised by a preset distance. The cartridge body N10 (including the drum frame 12 and the developing frame 11) is displaced relative to the first protrusion N701, thereby allowing the processing cartridge to be installed smoothly and avoiding installation failure due to interference between the pressing member N40 and the drive unit 1080 or interference from other components. Figure 75 As shown, the pressing member N40 finally presses against the outer circumferential surface of the small-diameter cylindrical body N1083 of the drive unit 1080. At this time, the drive 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 receiving part N105, and the rotation axis NL1 of the drive unit 1080 and the rotation axis NL2 of the photosensitive drum 20 are in an intersecting state.

[0454] 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 mesh and stably receive the driving force to rotate.

[0455] In this embodiment, since the pressing member N40 is fixedly mounted 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 straighten the drive unit 1080 can be the weight of the processing box 1 itself, or the force applied to the processing box 1 through the door cover 102 when the door cover 102 is closed. Optionally, the pressing member N40 can also be other parts of the driving unit 1080, as long as it can force it to straighten. Optionally, the guided part N70 can also be located at other positions on the box body N10, as long as it can move relative to the box body N10 and prevent interference between the processing box 1 and the electronic imaging device during the installation of the processing box. Alternatively, for electronic imaging devices where the drive unit 1080 is not locked, since the processing box will not be lifted when the pressing member N40 contacts the drive unit 1080, the guided part N70 can be omitted in this case. Alternatively, the pressing member N40 can also press the drive unit 1080 at other positions, as long as it can be aligned.

[0456] This embodiment, by providing a pressing component on the processing box, enables a smoother contact and engagement process between the power receiving unit and the drive unit, greatly saving the contact and engagement time between the power receiving unit and the drive unit, and improving the working efficiency of the processing box.

[0457] In some embodiments, the electronic imaging apparatus further includes a biasing device disposed below the drive unit 1080 and pressing down on the drive unit 1080 to keep it tilted. Similarly, in this embodiment, after the cover 102 is closed, the pressing member N40 resists the biasing force of the biasing device, allowing the drive unit 1080 to be aligned. The electronic imaging apparatus is not limited to this; the biasing device can also be disposed above the drive unit 1080. Some electronic imaging apparatuses also eliminate the cam N104; in this type of structure, the drive unit 1080 can be aligned without closing the cover 102 when the processing cartridge 1 is installed.

[0458] Example 15

[0459] Figures 77-80 This is a partial structural schematic diagram of the electronic imaging device in this embodiment. Figure 77As shown, there is an electronic imaging device 100, in which a processing box 1 can be detachably mounted. The electronic imaging device 100 includes a main component O101 for accommodating the processing box 1, a drive unit 1080, an openable and closable door cover O102, a connecting rod O103 that is linked to the door cover O102, and a cylindrical cam O104 that is linked to the door cover O102 via the connecting rod O103.

[0460] For ease of description, along the installation direction OY1 of the processing box, the side where the drive unit is located is the front, and the opposite side 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 opposite side is the left.

[0461] The main component O101 is provided with a receiving portion O105 for accommodating the processing box 1. The receiving portion O105 is provided with a first sidewall O106 and a second sidewall O107 along the length direction of the processing box 1. The first sidewall O106 and the second sidewall O107 are respectively provided with guide rails O108 for guiding the installation or removal of the processing box 1. The drive unit 1080 is provided on the second sidewall O107 of the receiving portion O105 for transmitting driving force to the processing box 1.

[0462] Furthermore, the electronic imaging device 100 also includes a cover 1081, which is disposed on the second sidewall O107 and protrudes from the second sidewall O107 toward the first sidewall O106 along the length of the processing box. At least a portion of the cover 1081 covers the driving unit 1080. Specifically, the cover 1081 includes a front plate 109a, a first side plate 109b, and a second side plate 109c, which are respectively connected to the front plate 109a. The front plate 109a has a first hole 1090a for the driving unit 1080 to extend from. The first hole 1090a is circular, allowing one end of the driving unit 1080 to extend from it. The first side plate 109b is located above the front plate 109a, and the second side plate 109c is located behind the front plate 109a. A second hole 1090b is formed between the first side plate 109b and the second side plate 109c, so that a portion of the drive unit 1080 can be exposed to the rear side of the cover 1081 through the second hole 1090b.

[0463] A cover O102 is rotatably mounted on the main assembly O101 to open or close the receiving portion O105. The cover O102 is mounted on the main assembly O101 rotatably about a pivot axis, thus allowing the receiving portion O105 to be opened or closed rotatably. A box-pressing member O1020 is provided on each side of the cover O102 along the axial direction of the pivot axis. Each of the two box-pressing members O1020 can move relative to the cover O102 within a predetermined range. During the closing of the cover O102, the box-pressing member O1020 can push against the force receiving portion O10a (described in detail below) provided on the processing box 1, so that the processing box can be installed and positioned stably in the main assembly O101.

[0464] Furthermore, the connecting rod O103, the cam O104 and the drive unit 1080 are located on the same side of the receiving part O105, and the connecting rod O103, the cam O104 and the door cover O102 form a linkage relationship so that the drive unit 1080 can be locked or unlocked when the door cover O102 performs a closing or opening action.

[0465] Figure 80 It is an exploded perspective view of the support structure of the drive unit. Figure 81 This is a structural diagram of the drive unit. (Example) Figure 80 and Figure 81 As shown, the electronic imaging device also includes a support side plate O82, which is disposed on the main component 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 in the support side plate O82. Further, 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 the end of the small-diameter portion 1080f. The power output portion 1080e is disposed on the small-diameter portion 1080f and is used to engage with the power receiving unit 21 of the processing box 1 to transmit driving force.

[0466] During the opening of the door cover O102, the cylindrical cam O104 moves along with the door cover O102. As a result, the cylindrical cam O104 contacts the drive unit 1080, and the drive unit 1080 moves together 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 supporting side plate 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 plate 109a, that is, the power output part 1080e is retracted into the cover 1081.

[0467] When the door cover O102 is closed, the drive unit 1080 is in the unlocked state. The drive unit 1080 can move under the action of external force, that is, it can change from the tilted state to the upright state (that is, the non-tilted state) under the action of external force and can extend from the cover 1081 so as to stably transmit driving force to the processing box 1.

[0468] The structure of the electronic imaging device is not limited to this. Some electronic imaging devices are also equipped with a bias device located on the lower side of the drive unit 1080 and pressing on the upper side or lower side of the drive unit 1080 to keep the drive unit 1080 in an inclined state.

[0469] Figure 82 This is a schematic diagram of the processing box in 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 rotatably connected 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 on the front side of the processing cartridge 1 along the installation direction, facing each other to perform developing and other operations. 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 disposed at the first end 1A of the housing O10, and the power receiving unit 21 includes a power receiving part O211. The power receiving part O211 can engage with the power output part 1080e to receive driving force, thereby driving the developing roller 30 and the photosensitive drum 20 to rotate.

[0470] Furthermore, in order to change the drive unit 1080 from its initial tilted state (in which the rotation axis OL1 of the drive unit 1080 is tilted relative to the rotation axis OL2 of the photosensitive drum 20) to an aligned state that can engage with the power receiving unit 21 (in which the rotation axis of the drive unit 1080 coincides with the rotation axis of the photosensitive drum 20), as follows: Figure 82 As shown, the processing box 1 also includes a pressure member O40, which is disposed at the first end 1A and is used to apply pressure to the drive unit 1080 so that the drive unit 1080 is in an upright position. Specifically, the pressure member O40 is fixedly mounted on the end cover O202 to form a fixed connection with the drum frame 12.

[0471] Furthermore, in the rotational axis direction OL2 of the photosensitive drum 20, the pressing member O40 is located outside the end of the power receiving part O211 so that it can cooperate with the drive unit 1080 during installation. Figure 83 As shown, on a plane perpendicular to the rotation axis of the photosensitive drum 20, at least a portion of the projection of the pressing part 402 of the cantilever O42 of the pressing member O40 coincides with or falls within the area of ​​the photosensitive drum 20.

[0472] like Figure 83 As shown, the processing box 1 also includes a charging roller O60, which is disposed in the box body O10 and is rotatable while in contact with the photosensitive drum 20. In other embodiments, the charging component is not limited to such a rotatable contact roller structure; for example, a charging component fixed to the photosensitive drum with a certain gap can be used. Figure 82 As shown, the pressing element O40 is located within the outer peripheral surface of the photosensitive drum 20, and the pressing element O40 is located above the line connecting the rotation center of the charging roller O60 and the rotation center of the photosensitive drum 20.

[0473] like Figure 84As shown, the pressing component O40 includes a fixing part O41 and a cantilever O42. The fixing part O41 is connected to the housing O10, and the cantilever O42 is connected to the fixing part O41 and extends toward the photosensitive drum. The fixing part O41 includes a mounting protrusion O401. In this embodiment, two mounting protrusions O401 are provided, with one mounting protrusion O401 located above the other. The end cover O202 has mounting holes corresponding to the mounting protrusions O401. During assembly, the mounting protrusions O401 engage with the mounting holes, fixing the pressing component O40 to the end cover O202 or the drum frame 12, allowing the pressing component O40 to move with the movement of the drum frame 12. When the processing cartridge is installed in the receiving part O105 of the electronic imaging device, the cantilever O42 passes through the second hole 1090b on the cover 1081 to press the drive unit 1080 of the electronic imaging device. It should be noted that there are no strict restrictions on the shape and structure of the fixing part, as long as it can ensure that the pressing part O40 is immovable relative to the axis of the photosensitive drum 20.

[0474] In this embodiment, the cantilever O42 is generally cuboid in shape, and includes an upper end face O42a located on the upper side of the cantilever O42 in the installed state and a lower end face O42b located on the lower side of the cantilever O42. The upper end face O42a and the lower end face O42b are arranged as mutually parallel planes. The lower end face 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 aligned.

[0475] Furthermore, the end of the cantilever O42 furthest from the fixed part O41 is provided with an arc-shaped guide surface. This guide surface connects the upper end surface O42a and the lower end surface O42b. It can guide the cantilever O42 to move along the outer circumferential 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, so as to avoid interference between the cantilever O42 and the drive unit during the installation of the processing box 1. The two sides of the cantilever O42 that are arranged opposite each other along the axis OL2 of the photosensitive drum 20 are configured as planes, and the maximum distance between the two sides 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 processing box is installed in place), so as to prevent the cantilever O42 from being unable to pass through the second hole 1090b.

[0476] Continue to refer to Figure 84As shown, due to the limitation of the distance or space between the input gear section 1080d of the drive unit 1080 and the front plate 109a, the thickness B of the cantilever O42 of the pressing member O40 is preferably 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 processing box 1, the cantilever O42 is prone to breakage or fracture due to the action of 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 prone to being unable to achieve the aligning effect on the drive unit 1080 due to the limitation of the distance between the input gear section 1080d of the drive unit 1080 and the front plate 109a.

[0477] Reference Figure 83 A force receiving part O10a is also provided on the rear side of the first end 1A of the box body O10. The force receiving part O10a is used to receive the force of the box pressing part O1020 when the door cover O102 is closed, so that the processing box 1 is installed in place.

[0478] The following details the installation method of installing the processor box into the printer.

[0479] like Figure 85 As shown, first, the door cover O102 is opened. Since the door cover O102 is in the open state, the drive unit 1080 is in the locked state. The guide protrusions on both sides of the processing box 1 along the length direction are aligned with the guide rails O108 on the first and second side walls of the receiving part O105. Then, the processing box 1 is pushed in along the OY1 direction. The pressing member O40 fixed on the end cover O202 also gradually moves closer to the drive unit 1080 as the processing box 1 moves, until the pressing member O40 contacts the drive unit 1080.

[0480] like Figure 86 As shown, with the processing box 1 installed in the receiving part O105 of the electronic imaging device and the door cover O10 open, the cantilever O42 of the pressing member O40 abuts against the upper side of the small-diameter portion 1080f of the drive unit 1080. Viewed from the rear of the processing box 1, the first end 1A of the processing box 1, i.e., the end where the power receiving unit 21 is located, is positioned higher in the electronic imaging device relative to the other end 1B of the processing box 1 (the processing box 1 is partially tilted upwards). This installation position of the processing box is referred to as the first position. At this time, the other end 1B of the processing box can be in the installed position.

[0481] like Figure 87 , Figure 88As shown, the door cover O102 of the electronic imaging device is then closed. As the door cover O102 closes, the cam O104 releases the lock on the drive unit 1080. The pressing member O1020 on the inside of the door cover O102 pushes the force receiving part O10a on the rear side of the processing box 1, causing the first end 1A of the processing box 1 to be subjected to force, which moves downward and drives the pressing member O40 to move downward. At this time, the front end of the pressing member O40 presses the drive unit 1080, causing it to move downward, so that the rotation axis OL2 of the drive unit 1080 coincides with or is substantially parallel to the rotation axis OL1 of the power receiving unit 21, thereby allowing the power receiving unit 21 to engage with the drive unit. At this time, the processing box 1 is in the second position. That is, after receiving pressure, the drive unit 1080 moves in the direction close to the power receiving unit 21. Under the pressure applied by the pressing member O1020 to the left and right sides of the processing box 1, the two ends (1A, 1B) of the processing box 1 remain substantially horizontal.

[0482] With the processing box 1 installed, the drive unit 1080 moves from its initial position to a position where it can engage with the power receiving unit 21. This allows the drive unit 1080 to transmit driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate. The installation position of the processing box in this position is called the second position. It should be noted that the force applied by the pressing member O40 to the drive unit 1080 to orient the drive unit 1080 can be the force applied to the processing box 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 processing box 1 itself.

[0483] The following describes the specific cooperation between the pressing component O40 and the drive unit 1080 during the installation process.

[0484] like Figure 89 As shown, during the installation of the processing box 1 onto the main component O101, the pressing member O40 can align the drive unit 1080 through the second hole 1090b. Before the processing box is installed, the drive unit 1080 is in an inclined state, and the rotation axis OL1 of the drive unit 1080 forms 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 is substantially coincident with the central axis OL0 of the cover member 1081.

[0485] When the processing box 1 is installed into the electronic imaging device along the OY1 direction, the lower end face O42b of the cantilever O42 of the pressing member O40 presses against the small-diameter portion 1080f of the driving unit 1080. Since the abutting surface 1080c of the driving unit 1080 contacts at least one of the first protrusion O82b or the second protrusion O82c of the supporting side plate O82, the driving unit 1080 tilts in the direction of arrow N, meaning the driving unit 1080 remains locked. When the door cover O102 is closed, the cylindrical cam O104 releases the lock on the driving unit 1080, and the box pressing member O1020 inside the door cover O102 presses against the force receiving portion O10a of the processing box 1, causing the first end 1A of the processing box 1 to be subjected to force. Alternatively, both sides of the box body O10 may simultaneously be subjected to the force of the box pressing member O1020. The first end 1A of the processing box 1 moves down and drives the pressing member O40 to move down. At this time, the lower end face 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 acted upon by the first protrusion O82b or the second protrusion O82c of the supporting side plate O82. The driving unit 1080 moves in the opposite direction of arrow N to straighten.

[0486] like Figure 90 and 91 As shown, the line connecting the fulcrum of the first protrusion O82b and the second protrusion O82c supporting the drive unit 1080 is defined as OL3. The axis parallel to OL3 and passing through the center of the rotation axis of the drive unit 1080 is defined as axis OL4. The 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 processing box 1 is in the first position and the second position, and during the process of 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.

[0487] The configuration of the compression component O40 can be varied in many ways, such as Figure 92 As shown, when viewed along the left and right direction of the mounting part, in the first position, the angle between the lower end face 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, which enables the installation with the electronic imaging device. If the angle β is less than 78° or greater than 113°, interference will occur when the processing box 1 is installed into the electronic imaging device 100, making it impossible to install the processing box or to align the drive unit 1080.

[0488] The processing box with the above structure enables a smoother contact and engagement process between the power receiving unit and the drive unit, greatly saving the contact and engagement time between the power receiving unit and the drive unit, making the transmission of driving force more stable, and improving the working efficiency of the processing box.

[0489] The processing box of this embodiment can also be applied to the electronic imaging device of the foregoing embodiments.

[0490] In this embodiment, the projection of the cantilever O42 at least partially coincides with the projection of the photosensitive drum 20. When the processing cartridge is installed into the electro-imaging device, the cantilever O42 presses against the small-diameter portion 1080f of the drive unit 1080, 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. Simultaneously, because the force applied to the small-diameter portion of the drive unit by the cantilever portion of the pressing member is smaller and more precise, the drive unit is aligned from an inclined position to a position close to coaxial with the photosensitive drum. Therefore, the contact and engagement process between the photosensitive drum or developing roller of the processing cartridge and the drive unit of the electro-imaging device is smoother, greatly saving the contact and engagement time between the photosensitive drum or developing roller and the drive unit, and improving the working efficiency of the processing cartridge.

[0491] Example 16

[0492] Unless otherwise specified, the structure of the processing box in this embodiment is basically the same as that of the processing box in Embodiment 15 in terms of shape, structure, installation and disassembly methods, and the similarities will not be repeated.

[0493] Figure 93 This is a simplified structural diagram of the processing box in this embodiment. In this embodiment, the power receiving unit located at the first end 1A of the photosensitive drum 20 in the length direction (i.e., the end near the drive unit 1080 in the installed state) is eliminated. Instead, the developing roller gear P301 located at the first end of the developing roller 30 in the length direction (i.e., the end near the drive unit 1080 in the state of being installed in the electronic imaging device) serves as the power receiving unit. The developing roller gear P301 is engaged 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 be a single-tooth structure with bevel teeth or spiral arrangement. Optionally, its upper teeth can be designed as helical teeth to better mesh with the helical teeth portion of the drive unit 1080. Optionally, 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.

[0494] Furthermore, the processing 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 the opposite end of the developing roller 30 along its length, and the photosensitive drum gear P201 is disposed at a first end or the opposite end of the photosensitive drum 20. The photosensitive drum gear P201 can mesh 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 design, the processing 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 to rotate.

[0495] In other embodiments, the developing roller gear P301 may include a helical tooth portion and a spur tooth portion. The helical tooth portion is used to mesh with the gear portion 1080d of the drive unit 1080 to receive driving force, and the spur tooth portion is used to transmit driving force to the photosensitive drum gear P201. Correspondingly, a photosensitive drum gear for meshing with the spur tooth portion of the developing roller gear P201 can 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 can be omitted, while the power receiving unit provided at the first end of the photosensitive drum 20 can be retained. The power receiving unit can mesh with the drive unit 1080 to receive driving force. Similarly, a photosensitive drum gear can be provided at the first end or the end opposite to the first end of the photosensitive drum 20, and a developing roller gear can be provided at the first end or the other end opposite to the first end of the developing roller 30, and the developing roller gear meshes with the photosensitive drum gear so that the developing roller 30 can receive driving force. Alternatively, in addition to gear transmission, the transmission of driving force between the developing roller 30 and the photosensitive drum 20 can also employ a friction wheel, such as a rubber wheel. Alternatively, the gear that meshes with the drive unit 1080 and receives driving force can be located at the end of the developing roller, or it can be separate from the developing roller 30, for example, located on the end cap. It can mesh with the gear portion 1080d of the drive unit 1080 to receive driving force, and then transmit the driving force to rotating components such as the developing roller 30 and the photosensitive drum 20.

[0496] Example 17

[0497] Unless otherwise specified, the structure of the processing box in this embodiment is basically the same as that of the processing box in Embodiment 15 in terms of shape, structure, installation and disassembly methods, and the similarities will not be repeated.

[0498] Figure 94A modified structure of the pressing member Q40 in this embodiment is shown. In this embodiment, the upper end face Q42a and the lower end face Q42b of the cantilever Q42 of the pressing member Q40 are both curved surfaces. When the processing box is installed in the electronic imaging device, compared to the above embodiment, the lower end face Q42b of this embodiment is concave upwards, and the upper end face Q42a is convex upwards. This structural design allows the lower end face Q42b to better pass over the second side plate 109c of the electronic imaging device during the installation of the processing box, avoiding interference with the second side plate 109c.

[0499] Figure 95 In another variation of the pressing member Q40 in this embodiment, both the upper end face Q42a and the lower end face Q42b of the cantilever Q42 of the pressing member Q40 are curved surfaces. With the processing box installed in the receiving part Q105, compared to the above embodiment, the lower end face Q42b of this embodiment protrudes downwards, while the upper end face Q42a is recessed downwards. This structural design, with the lower end face Q42b of the cantilever Q42 having a curved surface, can provide a certain guiding effect.

[0500] It should be noted that the shape and structure of the cantilever are not limited to this. Other deformations are also possible, such as the upper end face being convex upward and the lower end face being convex downward; or the upper end face being concave downward and the lower end face being concave downward; or the cantilever being cylindrical, conical, or prismatic, etc., as long as it can compress the drive unit.

[0501] Example 18

[0502] Figure 96 This is a schematic diagram of the electronic imaging device in this application. Figure 96 As shown, an electronic imaging device 100 is provided, in which a processing box 1 is detachably housed. The electronic imaging device 100 includes an openable and closable door cover R101, a pushing part R102 that is linked to the door cover R101, and a drive unit 1080. Figure 102 The drive unit is the output component of the driving force.

[0503] Figure 97 This is a schematic diagram of the processing box in this application. Figure 98 This is an exploded view of the processing box structure in this application. Figure 97 , Figure 98As shown, the processing 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 developer, and the photosensitive drum 20 and the developing roller 30 are rotatably disposed 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 section R21a, which receives the driving force output by the driving unit 1080 in the electronic imaging device, thereby causing the photosensitive drum 20 to rotate.

[0504] Furthermore, the processing box 1 also includes a pressing member R40. During the engagement of 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 box body R10 includes a bracket R11, and the pressing member R40 is fixedly mounted on the bracket R11. At least a portion of the pressing member R40 is located inside the outer peripheral surface of the photosensitive drum 20. During the contact 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.

[0505] Specifically, such as Figure 98 , Figure 99 As shown, the bracket R11 includes a slide groove R111, a mounting part R112, a recess and a protrusion R11a. The protrusion R11a is disposed in the slide groove R111 and is used to fix one end of the elastic member R511. The recess R113 is used to install the pressing member R40.

[0506] like Figure 100 As shown, the processing box 1 also includes a control mechanism R50, which cooperates with the power receiving unit 21 to control the extension and retraction state of the power receiving unit 21, that is, to control the power receiving unit 21 to move axially along the photosensitive drum 20. Further, 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 component R52, and a limiting component R53. The push rod R51 is movably mounted in the slide groove R111. The linkage component R52 and the limiting component R53 cooperate with each other and are sleeved on the power receiving unit 21, and the linkage component R52 is movably connected to the push rod R51. The elastic component R511 is disposed on the push rod R51 and one end is connected to the protrusion R11a for resetting the push rod R51. In this embodiment, the elastic component R511 is a spring; in other embodiments, the elastic component R511 can also be other elastic materials, such as rubber, silicone, sponge, etc.

[0507] 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 member 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 surface R53b. As the processing box 1 is in different states, the linkage member R52 can move between the second protrusion R53a and the flat surface R53b of the limiting member R53. The specific operation will be described in detail later.

[0508] Figure 101a This is an exploded view showing the installation of the power receiving unit and the photosensitive drum. (See diagram below.) Figure 101a As shown, the power receiving unit 21 includes a power receiving part R21a, a power output part R21b, an intermediate part R23, and an elastic member R22. The intermediate part R23 is disposed at one end of the photosensitive drum 20. The power receiving part R21a is movably disposed on the intermediate part R23 and passes through the linkage member R52 and the limiting member R53, for contacting and engaging with the drive unit of the electronic imaging device to receive the driving force output from the electronic imaging device. The power output part R21b is connected to the power receiving part R21a and is used 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 part R23, with one end of the elastic member R22 connected to the intermediate part R23 and the other end 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 other elastic materials, such as rubber, silicone, sponge, etc.

[0509] Figure 101b This is a partial view of the photosensitive drum and 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 disposed at the end of the developing roller 30, and the photosensitive drum gear R201 is disposed at the end of the photosensitive drum 20. The photosensitive drum gear R201 meshes with the intermediate gear R301, so that the developing roller 30 can receive driving force through the intermediate gear R301 and the photosensitive drum gear R201, thereby causing the developing roller 30 to rotate.

[0510] Figure 102 This is a schematic diagram of the drive unit structure of the electronic imaging device in this application. The drive unit 1080 includes a gear portion 1080d, a small diameter portion 1080f, and a engagement portion 1080e. During the contact and engagement between the power receiving unit and the drive unit of the electronic imaging device, the pressing member R40 presses the small diameter portion 1080f of the drive unit 1080, thereby achieving the function of aligning the drive unit 1080. The detailed alignment process will be described in detail below.

[0511] Figure 103 This is a partial schematic diagram of the power receiving unit in its retracted state in this application. Figure 103 As shown, when the processing box 1 is installed into the electronic imaging device (not shown), and the door cover R101 of the electronic imaging device is not yet closed, the pressing member R40 presses the small-diameter portion 1080f of the driving unit 1080, but at this time the driving unit 1080 of the electronic imaging device 100 is still in an inclined state. The elastic member 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, so that the elastic member R22 provided between the power receiving unit 21 and the intermediate member R23 is compressed, and the amount of compression is called the first compression amount. At this time, the plane of the power receiving part R21a of the power receiving unit 21 is located inside the plane of the linkage member R52 or flush with the plane of the linkage member R52, or it can be in an extended state, as long as it does not cause interference during installation. In this state, the power receiving unit 21 is not combined with the driving unit 1080.

[0512] Figure 104 This is a partial schematic diagram of the power receiving unit in the extended state in this application. When the door cover R101 of the electronic imaging device is fully closed, the pressing member R40 has completed the alignment of the drive unit 1080, and the drive unit 1080 is in the aligned state. At this time, the door cover R101 is fully closed, and the push rod R51 of the control mechanism R50 is acted upon by the pushing part R102, compressing the elastic member R511, thereby driving the linkage member R52 to rotate. The first protrusion R52b of the linkage member R52 changes from contacting the second protrusion R53a of the limiting member R53 to contacting the flat part R53b. The elastic member R22 provided between the power receiving unit 21 and the intermediate member R23 is compressed. The amount of compression at this time is called the second compression amount. Since the linkage member R52 has the function of axial movement, the first compression amount is greater than the second compression amount. Therefore, in this state, the power receiving unit 21 is in the extended state, that is, the plane of the power receiving part R21a of the power receiving unit 21 protrudes out of the plane of the linkage member R52. Since the drive unit 1080 is now aligned, the power receiving part R21a of the power receiving unit 21 is connected to the engagement part 1080e of the drive unit 1080, thus completing the engagement.

[0513] Example 19

[0514] This embodiment discloses a processing cartridge, which includes a cartridge body, a photosensitive drum, a developing roller, a power receiving unit, and a pressing member. The photosensitive drum and the developing roller are rotatably disposed in the cartridge body, and the power receiving unit is connected to the photosensitive drum. The pressing member is disposed in the cartridge body and located at the same end of the cartridge body as the power receiving unit, and the pressing member is capable of displacement relative to the cartridge body to align the position of the drive unit of the electronic imaging device, enabling the drive unit to engage with the power receiving unit and transmit the output driving force of the drive unit to the photosensitive drum and the developing roller.

[0515] 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 may also be connected to the developing roller, or there may be two power receiving units, one of which is connected to the photosensitive drum and the other is connected to the developing roller.

[0516] 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 processing box 1. The processing box also includes an elastic member S60 (such as a spring, magnet, elastic sponge, etc.). The pressing member S40 is connected to the end of the box body via the elastic member S60, allowing the pressing member S40 to move relative to the box body in a direction parallel or approximately parallel to the axial direction of the photosensitive drum under the action of the elastic member S60, thereby pressing the drive unit 1080. The direction approximately 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 this angle can be within ±5°.

[0517] Furthermore, the pressing member S40 includes a rod coaxially arranged with the photosensitive drum 20 and a protrusion S41 formed by bending and extending from one end of the rod. The rod is connected to the housing through an elastic member S60. The protrusion S41 is arranged close to the power receiving unit 21 and is used to press down the drive unit of the electronic imaging device so that the drive unit and the power receiving unit 21 are basically coaxially engaged to transmit power.

[0518] When the elastic element S60 is in a compressed state, the pressing element S40 can move along the length of the processing box 1 or the axial direction of the photosensitive drum 20, causing the pressing element S40 to move away from the drive unit 1080. When the elastic element S60 is in a relaxed state, the pressing element S40 can move along the length of the processing box 1 or the axial direction of the photosensitive drum 20, causing the pressing element S40 to move closer to the drive unit 1080 and drive the drive unit 1080 to press down.

[0519] In this embodiment, during or after the installation of the electronic imaging device, the pressing component S40 can move along the length of the processing box 1 or the axial direction of the photosensitive drum 20 and press the driving unit, thereby aligning the position of the driving unit 1080 of the electronic imaging device, making the driving unit 1080 coaxial or substantially coaxial with the power receiving unit 21, and then making the driving unit 1080 mesh with the power receiving unit 21 to transmit power, and transmitting the driving force output by the driving unit 1080 to the photosensitive drum and the developing roller.

[0520] Example 20

[0521] This embodiment provides another processing box. The parts not described are the same as those in the previous embodiments, and will not be repeated for the sake of simplicity.

[0522] The difference between this embodiment and the above embodiments is that the pressing component in the processing box of this embodiment is sleeved on the outside of the power receiving unit and rotates coaxially with the photosensitive drum.

[0523] Specifically, such as Figure 107 and Figure 108 As shown, the processing box also 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 located inside the photosensitive drum 20, and the power receiving unit 21 is connected to the photosensitive drum 20 via the telescopic mechanism T70, allowing the power receiving unit 21 to move axially in the photosensitive drum 20. Optionally, the telescopic mechanism T70 is an elastic member, which can be a spring, magnet, elastic sponge, or other components with elastic force; no limitation is made here.

[0524] In this embodiment, the elastic element is a spring, and the end of the photosensitive drum 20 is provided with a groove 20a, in which the spring is received.

[0525] The pressing member T40 is sleeved on the outside of the power receiving unit 21 away from the telescopic mechanism T70, and the pressing member T40 can rotate coaxially with the photosensitive drum 20, so that the pressing member T40 can move along the axial direction of the photosensitive drum 20 with the power receiving unit 21. In this embodiment, the pressing member T40 is a rotatable sleeve, which can be a hollow cylinder. The power receiving unit 21 is housed in the sleeve and can move along the sleeve.

[0526] Specifically, one end of the telescopic mechanism T70 (elastic element) abuts against the inner wall of the groove 20a, and the other end of the telescopic mechanism T70 (elastic element) abuts against the power receiving unit 21.

[0527] When the processing box 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 retract into the pressing member T40. When the processing box is installed in the electronic imaging device, the drive unit 1080 is in an inclined 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 outside 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 starts to rotate and drives the pressing member T40 to rotate. During the rotation of the pressing component T40, the centrifugal force generated by the pressing component T40 causes the drive unit 1080 to gradually move from its original tilted state to a position where the axis of the drive unit 1080 coincides with the axis of the photosensitive drum 20. At this time, the drive unit 1080 and the photosensitive drum 20 are coaxial. After the pressing component T40 rotates centrifugally, the friction between the power receiving unit 21 and the pressing component T40 decreases. The elastic force of the telescopic mechanism T70 drives the power receiving unit 21 to move along the axis of the photosensitive drum 20 toward the direction closer to the drive unit 1080. Through this movement of the power receiving unit 21, the power receiving unit 21 extends out of the pressing component T40, thereby successfully engaging with the drive unit 1080 and realizing the power transmission between the drive unit 1080 and the photosensitive drum 20.

[0528] Example 21

[0529] 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 there may be three; the number is not limited. Both the power receiving unit U22 and the pressing member U23 can move relative to the housing in the axial direction of the photosensitive drum 20. The pressing member U23 can also move relative to the power receiving unit U22 in a first planar region in a direction perpendicular to the axial direction of the photosensitive drum 20. The pressing member U23 can be used to align the position of the driving unit 1080, and the power receiving unit U22 can engage with the driving unit of the electronic imaging device. In the plane perpendicular to the axial direction of the photosensitive drum, the projection of the first planar region at least partially coincides with the projection of the photosensitive drum.

[0530] Furthermore, the processing box also includes a first elastic element U211 and a second elastic element U231. The power receiving unit U22 and the pressing element U23 are connected to the photosensitive drum 20 via the first elastic element U211. The first elastic element U211 enables the power receiving unit U22 and the pressing element U23 to translate along the axial direction of the photosensitive drum 20. The pressing element U23 is connected to the power receiving unit U22 via the second elastic element U231. The second elastic element U231 enables the pressing element U23 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 element U211 is disposed on the inner wall U2100 of the drive gear, and the other end is directly or indirectly disposed on the inner side U210 of the power receiving unit U22 and the pressing element U23 facing the inner wall of the drive gear. When the first elastic element U211 deforms under force (e.g., compression), the power receiving unit U22 and the pressing element U23 can translate along the photosensitive drum axis toward the direction of insertion into the processing box. When the first elastic element U211 releases its elastic force (e.g., extension), the power receiving unit U22 and the pressing element U23 can translate along the photosensitive axis axis toward the direction of extension out of the processing box. Alternatively, conventional structures such as limiting structures can be provided to prevent the power receiving unit U22 and the pressing element U23 from detaching from the processing box, thereby enabling the power receiving unit U22 and the pressing element U23 to translate along the photosensitive drum axis. In this embodiment, the initial state of the first elastic element U211 is such that the power receiving unit U22 and the pressing element U23 are in a compressed state, extending into the processing box. The second elastic element U231 acts only on the pressing element U23. The second elastic element U231 gives the pressing element U23 the ability to stretch and contract in a direction perpendicular to the axial direction of the photosensitive drum, so that the pressing element U23 can generate displacement in a direction perpendicular to the axial direction of the photosensitive drum, and is not limited to moving only in the axial direction. The second elastic element U231 can be configured similarly to the first elastic element U211. One end of it can be disposed on the inner wall of the drive gear or on the power receiving unit U22. In this embodiment, it is disposed on a wall U220 inside the power receiving unit U22. The other end is disposed directly or indirectly on the pressing element U23. The initial state of the second elastic element U231 is such that the pressing element U23 is compressed in a direction perpendicular to the axial direction of the photosensitive drum. When the second elastic element U231 releases its elastic force (e.g., stretches), the pressing element U23 can be translated away from the power receiving unit U22 in a direction perpendicular to the axial direction of the photosensitive drum. When the second elastic element U231 is deformed by force (e.g., compressed), the pressing element U23 can be translated closer to the power receiving unit U22 in a direction perpendicular to the axial direction of the photosensitive drum. For setting and maintaining the initial state of the second elastic member U231, it is preferable to provide a limiting part U2311, which is a block or strip-shaped component fixedly provided in the box body to limit the position of the pressing member U23.In this embodiment, the limiting method is that the limiting part U2311 of the strip-shaped component "supports" the pressing member U23, that is, the second elastic member U231 compresses and causes the pressing member U23 to abut against the limiting part U2311, and the pressing member U23 and / or the second elastic member U231 can move relative to the limiting part U2311. The movement can be in the form of the pressing member U23 and / or the second elastic member U231 sliding on the limiting part U2311.

[0531] Furthermore, the processing box also includes a control lever U810 and a rotatable latch U820. The control lever U810 is used to receive an external force, such as when the door cover 13 of the electronic imaging device is closed, and then controls the aforementioned power receiving unit U21 to extend out of the processing box along the photosensitive drum axis. The latch U820 is disposed in the box body and can rotate about the rotation axis U821. The latch U820 can prevent the power receiving unit U21 from moving axially in the photosensitive drum. Figure 110 As shown, when the processing box is installed in the electronic imaging device, the drive unit 1080 is in an inclined 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, causing the control lever U810 to control the aforementioned power receiving unit 21 to extend out of the processing box along the photosensitive drum axis, as... Figures 110 to 111 The movement process involves several steps. First, the buckle U820 can prevent the power receiving unit U22 from extending, allowing the pressing member U23 to extend. This does not affect the extension of the first elastic member U211. Alternatively, the first elastic member U211 can be divided into two parts, controlling the power receiving unit U22 and the pressing member U23 respectively. Furthermore, as the pressing member U23 and / or the second elastic member U231 move away from the power receiving unit U22, they will also experience relative displacement with the fixed limiting part U2311. Figure 111 Move to Figure 112 When the state is reached, the restriction 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 slide 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 get rid of the restriction of the limiting part U2311. During this process, the pressing member U23 extends outward so as to abut against the driving unit 1080. The pressing member U23 forms a certain pressure on the driving unit 1080, guiding the driving unit 1080 to gradually rotate and align until it forms a certain position. Figure 112 In the state shown, the pressing member U23 extends fully outward and abuts against the drive unit 1080, causing the drive unit 1080 to move from an inclined 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 and the drive unit 1080 are not yet fully engaged. Further, as... Figure 113As shown, when the latch U820 of this embodiment is triggered or rotates automatically, its blocking effect on the power receiving unit U22 is released, thereby allowing the power receiving unit U22 to extend out of the processing box under the extension action of the first elastic member U211, thus smoothly contacting and engaging with the aligned drive unit 1080. This state completes the full engagement of the power receiving unit 21 and the drive unit 1080.

[0532] Furthermore, an inclined surface U2312 may be provided on the limiting part U2311 (such as a free end) to assist the pressing part U23 in returning to its original position in the direction of the photosensitive drum axis and in the direction perpendicular to the photosensitive drum axis.

[0533] Furthermore, in such Figures 110 to 111 In this embodiment, the movement of the power receiving unit U22 in the photosensitive drum axis can be blocked without relying on the buckle U820. Instead, the blocking effect is achieved by the drive unit 1080 or the drive unit protective cover 1081 located outside the drive unit 1080. 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. After being aligned, it extends further outward to complete the engagement, which can also achieve the purpose of this embodiment.

[0534] Example 22

[0535] like Figure 114 As shown, the processing box 1 also includes a control mechanism V30. The control mechanism V30 can be fixed to the processing box 1 by being mounted on a guide rail (not shown in the figure) on the end cover. The control mechanism V30 can move along the guide rail in a direction perpendicular to the length direction of the processing box. Specifically, the control mechanism V30 has a first end V31 and a second end V32, wherein the end of the second end V32 also has an inclined surface V322. Optionally, the control mechanism in this embodiment can be a push rod.

[0536] Figure 115 This is a schematic diagram of the force receiving section of the power receiving unit in Embodiment 22. Figure 116 This is a schematic diagram of the force transmission section of the power receiving unit in Embodiment 22. Figure 117 This is a schematic diagram of the flange structure of the power receiving unit in Embodiment 22. Figure 115 and Figure 116 As shown, the power receiving unit 21 includes a force receiving part V22, a force transmitting part V23, and a flange V24.

[0537] Specifically, the force receiving part V22 is provided with a protrusion V221 for receiving driving force from the electronic imaging device, a protrusion V222, and two first fixing posts V223 provided on both sides of the protrusion V222. The force transmitting part V23 includes a connecting part V232, a groove V231 provided at one end of the connecting part V232 for engaging with the force receiving part V22, a limiting surface V234 provided at the other end of the connecting part V232, and a slot V235, wherein the second fixing posts V233 are respectively provided on both sides of the groove V231. Furthermore, the flange V24 is a circular component. The flange V24 has a receiving portion V242, in which a positioning post V243 and an elastically deformable swing member V244 are provided. In addition, an abutting portion V241 is provided extending along the outer circumference of the flange V24. An abutting surface V2411 is provided at one end of the abutting portion V241. Specifically, the abutting surface V2411 is an inclined surface.

[0538] Figure 118 This is a structural schematic diagram of the load-bearing component in Embodiment 22. Figure 118 As shown, the support member V50 includes a support portion V51, a through hole V52, and a plurality of first protrusions V53 arranged circumferentially on the outer side of the support portion V51.

[0539] Specifically, such as Figure 119 As shown, the assembly relationship between the power receiving unit 21 and the carrier V50 is as follows: the force receiving part V22 is mounted on the groove V231 of the force transmitting part V23 via the protrusion V222, thereby fixing it to the force transmitting part V23 and allowing the force receiving part V22 to pass through the groove V231 along the LL direction ( Figure 119The force receiving part V22 slides in a direction parallel to the groove V231, and when it receives the driving force of the electronic imaging device, it can move the power transmission part V23 together. At the same time, the two first fixed posts V223 of the force receiving part V22 and the two second fixed posts V233 of the force transmission part V24 are connected by the first elastic member V61, so that the force receiving part V22 can be reset when it no longer receives the driving force. When the first elastic member V61 is in its natural state, the force receiving part V22 extends outward relative to the force transmission part V23. The force transmission part V23 is disposed in the receiving part V242 of the flange V24. At this time, the limiting surface V234 of the force transmission part V23 abuts against the receiving part V242. The positioning post V243 in the flange V24 is connected to the connecting part V232 of the force transmission part V23 through the second elastic member V63, so that the force receiving part V22, which is movably connected to the force transmission part V23, can be biased at a predetermined phase. The swing member V244 is used to contact the second elastic member V63 during the process of the force transmission part V23 rotating after receiving power from the force receiving part V22 to prevent it from failing to reset. After the components of the power receiving unit 21 are installed sequentially, they can be installed together into the carrier V50. The force transmission part V23 passes through the through hole V52 of the carrier V50, thereby fixing the power receiving unit 21 into the carrier V50. At the same time, the third elastic element V64 is sleeved on one end of the force transmission part V23 passing through the through hole V52. One end of the third elastic element V64 abuts against the carrier part V53 of the carrier V50, and the other end abuts against the clutch V80. The clutch V80 is connected to the force transmission part V23 through a pin (not shown in the figure) passing through the slot V235. Multiple second protrusions V81 are arranged in a circular pattern on the end of the clutch V80 facing the carrier V50. All the above-mentioned components can be assembled together in the photosensitive drum 20. (See Figure 20) Figure 119 .

[0540] In this embodiment, the pressing member is integrated into the power receiving unit, and the power receiving unit V22 is movable within a first planar region along a first direction for engaging with the drive unit 1080 and aligning the position of the drive unit. Specifically, on a plane perpendicular to the axial direction of the photosensitive drum, the projection of the first planar region at least partially coincides with the projection of the photosensitive drum, and the first direction intersects the axial direction of the photosensitive drum but is not perpendicular to it. Figure 119 The LL direction in the middle.

[0541] The following describes the process of contact engagement and disengagement between the power receiving unit of the processing box and the drive unit of the electronic imaging device.

[0542] like Figure 119 and Figure 120As shown, when the processing box 1 is not yet installed in the electronic imaging device or when it is installed in the electronic imaging device but does not receive external force, the power receiving unit 21 is in the 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.

[0543] like Figure 121 As shown, when the processing box 1 is installed in the electronic imaging device and the door is closed, the control mechanism V30 on the processing box 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 the position of contacting the abutment surface V2411 of the flange V24. As the control mechanism V30 continues to move, the inclined surface V322 successfully abuts against the abutment surface V2411 and applies a force to the flange V24 in the X direction. Due to the limiting surface V234 of the force transmission part V23 and the flange V24, the force transmission part V24 is subjected to a force in the X direction. The receiving portion V242 of the flange V24 abuts against the force, and the clutch V80 is movably connected to the force transmission portion V23. Therefore, after the flange V24 is subjected to a force, it moves along the Y4 direction (i.e., towards the drive unit 1080) together with the force transmission portion V23, the force receiving portion V22, and the clutch V80. At this time, the force receiving portion V22 moves along the Y4 direction and extends to the position abutting against the drive unit 1080 in the electronic imaging device, that is, the protrusion V221 of the force receiving portion V22 engages with the electronic imaging device. In the drive unit 1080 of the device, the drive unit 1080 in the electronic imaging device is still in an inclined state. 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, since it is already connected to the drive unit 1080, can no longer move along the force transmission part V23 in the Y4 direction. 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 translates in the drive unit 1080. This 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 concave part of the drive unit 1080, it drives the drive unit 1080 to move, thereby moving the drive unit 1080 from the initial inclined state to a position where its axis is basically parallel or coaxial with the axis of the photosensitive drum 20.

[0544] like Figure 122 and Figure 123As shown, after the control mechanism V30 moves into place, the flange V24 stops moving when it abuts against the drive unit protective cover 1081. At this time, the clutch V80 also overcomes the elastic force of the third elastic member V64 and moves to the position of contact with the carrier member V50. The second protrusion V81 of the clutch V80 successfully engages with the first protrusion V53 of the carrier member V50. At this time, the force receiving part V22 also drives the drive unit 1080 to move to the position coaxial with the photosensitive drum 20, thereby realizing the transmission of driving force between the drive unit 1080 and the photosensitive drum.

[0545] When the door cover of the electronic imaging device is opened, the external force on the control mechanism V30 disappears. At this time, the flange V24 retracts in the opposite direction to the Y4 direction and moves together with the power transmission part V23. At this time, the clutch V80 also moves in the opposite direction to the Y4 direction. The third elastic element V64 resets after losing the force of the clutch V80. 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.

[0546] Example 23

[0547] This embodiment provides another control mechanism, which is a further improvement on the basis of embodiment twenty-two. The parts not described are the same as those in the foregoing embodiments, and will not be repeated for the sake of simplicity.

[0548] like Figure 124 As shown, the control mechanism W30 is movably disposed on the end of the housing. Specifically, the control mechanism W30 includes a first end W31, a second end W32, and a shaft hole W33, wherein a bevel 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 in the figure) through the shaft hole W33 to be fixed to the housing, thereby allowing the control mechanism W30 to swing in a plane perpendicular to the axial direction of the photosensitive drum 20.

[0549] Furthermore, the control mechanism on the processing box can also be a power source. When the control mechanism is a power source, it can receive commands by closing the door of the electronic imaging device, thereby operating the flange, force receiving unit, and force transmitting unit to extend towards the drive unit, and can control the power receiving unit 21 to extend a certain distance before stopping. Optionally, the power source can be a motor, photoelectric power, etc.

[0550] The process of contact and engagement between the power receiving unit and the drive unit of the electronic imaging device: When the processing box has not yet been installed into the electronic imaging device or has been installed into the electronic imaging device but has not received external force, the power receiving unit 21 is in the 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.

[0551] When the processing box 1 is installed into the electronic imaging device and the door is closed, the control mechanism W30 on the processing box is subjected to an external force and swings in 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 where it contacts 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 abuts against the receiving portion V242 of the flange V24, and the clutch V80 is movably connected to the force transmission portion V23. Therefore, after the flange V24 is subjected to force, it moves along the Y4 direction (i.e., towards the drive unit 1080) together with the force transmission portion V23, the force receiving portion V22, and the clutch V80. At this time, the force receiving portion V22 moves along the Y4 direction and extends to the position abutting against the drive unit 1080 in the electronic imaging device, that is, the protrusion V22 of the force receiving portion V22. 1. The drive unit 1080 in the electronic imaging device is connected to the card. At this time, the drive unit 1080 in the electronic imaging device is still in an inclined state. At the same time, as the control mechanism W30 continues to move, the flange V24 drives the force transmission part V23 to move along the Y4 direction. However, the force receiving part V22, since it is already connected to the drive unit 1080, can no longer move along 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 translates in the drive unit 1080. This 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 concave part of the drive unit 1080, it drives the drive unit 1080 to move. This causes the drive unit 1080 to move from the initial inclined state to a position where its axis is basically parallel or coaxial with the axis of the photosensitive drum 20.

[0552] After the control mechanism W30 moves into place, the flange V24 stops moving when it abuts against the drive unit protective cover 1081. At this time, the clutch V80 also overcomes the elastic force of the third elastic member V64 and moves to the position of contact with the carrier member V50. The second protrusion V81 of the clutch V80 successfully engages with the first protrusion V53 of the carrier member V50. At this time, the force receiving part V22 also drives the drive unit 1080 to move to the position coaxial with the photosensitive drum 20, thereby realizing the transmission of driving force between the drive unit 1080 and the photosensitive drum.

[0553] When the door cover of the electronic imaging device is opened, the external force on the control mechanism W30 disappears. At this time, the flange V24 retracts in the opposite direction to the Y4 direction and moves together with the power transmission part V23. At this time, the clutch V80 also moves in the opposite direction to the Y4 direction. The third elastic element V64 resets after losing the force of the clutch V80. 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.

[0554] Example 24

[0555] Figure 125 This is a schematic diagram of the electronic imaging device in Embodiment 24. As shown in the figure, there is an existing electronic imaging device 100, in which a processing box 1 is detachably housed. The electronic imaging device 100 includes an openable and closable door cover 101, a pushing part 102 that is linked to the door cover 101, and a driving unit 1080. Figure 131 ), which is the output component of the driving force.

[0556] Figure 126 This is a schematic diagram of the processing box in Example 24. Figure 126 As shown, the processing cartridge 1 includes a cartridge body X50, a photosensitive drum 20, a developing roller 30, a support X51, a pressing element 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 support X51 is located at the end of the cartridge body X50. The pressing element X40 can align the drive unit 1080, and the power receiving unit is used to engage with the drive unit 1080 to receive the driving force output by the drive unit in the electronic imaging device. The cartridge body X50 contains developer.

[0557] Figure 127 This is a schematic diagram of the support for the processing box in Example 24. Figure 127 As shown, bracket X51 is disposed on one side of housing X50 for mounting pressing component X40, and bracket X51 includes sliding groove X51a, mounting part X51b and connecting hole X51c. Push rod X41 is installed in sliding groove X51a, and telescopic rod 43 is sleeved on mounting part X51b.

[0558] Figure 128 This is a schematic diagram of the pressing component in Example 24. Figure 128As shown, the pressing component 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 the bracket X51 and can move along the photosensitive drum axis. The push rod X41 is movably mounted on the bracket X51 and connected to the telescopic member X43 via the connecting member X42, allowing the push rod X41 to drive the telescopic member X43 to move along the photosensitive drum axis. The first elastic member X41a is fitted onto the push rod X41 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 is connected to the inner wall of the mounting portion X51b, also for resetting 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 component X43 includes a second connecting portion X43b, which is used to connect to the other end of the connecting component X42. It should be noted that in this application, the first elastic component X41a and the second elastic component X43a are springs, or other components with elastic deformation. The connecting component X42 can be made of a flexible and deformable material. In this embodiment, a double-spring structure is used, which makes the repositioning of the telescopic component X43 more effective and reduces the possibility of interference when removing the processing box.

[0559] Figure 129 This is a schematic diagram of the compression member installed on the bracket in Example 24. Figure 129 As shown, push rod X41 is installed in the slide groove X51a of bracket X51, telescopic member X43 is sleeved in the mounting part X51b of bracket, and one end of connector X42 is installed on the first connecting part X41b of push rod X41, and the other end is connected to the second connecting part X43b of telescopic member X43 through the connecting hole X51c of bracket X51. Furthermore, the mounting part X51b has a fixing part for mounting one end of second spring X43a and a slit for the second connecting part X43b to extend out. Simultaneously, during the alignment of the drive unit by telescopic member X43, the second connecting part X43b can slide within the slit.

[0560] Figure 130 This is a partial view of the pendulum rod in Example 24. Specifically, as shown... Figure 130 As shown, the power receiving unit 21 is disposed at the end of the developing roller 30 and meshes with the drive unit 1080 of the electro-imaging device to receive the driving force output by the drive unit, thereby causing the developing roller 30 to rotate. Further, an intermediate gear X32 is disposed on the developing roller 30, and a photosensitive drum gear X211 is disposed at the end of the photosensitive drum 20. The photosensitive drum gear X211 meshes with the intermediate gear X32 to receive the driving force, thereby enabling the photosensitive drum 20 to receive the driving force output by the drive unit through the developing roller 30, allowing the photosensitive drum and the developing roller to rotate. In this embodiment, the power receiving unit is a gear.

[0561] Figure 131 This is a schematic diagram of the drive unit structure of the electronic imaging device in Embodiment 24. The drive unit 1080 includes a gear portion 1080a, a small-diameter portion 1080b, and an inclined portion 1080c. During the 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. At the same time, the telescopic rod X43 of the pressing member X40 extends to press the inclined portion of the drive unit 1080, thereby achieving the function of aligning the drive unit 1080. The detailed alignment process will be described in detail below.

[0562] Figure 132a This is a schematic diagram showing the state of the pressing member and the drive unit of the electronic imaging device when the processing box 1 is in its initial position in Embodiment 24. When the processing box 1 is installed into the electronic imaging device (not shown), and the door cover 101 of the electronic imaging device is not yet closed, the pressing member X40 of the processing box 1 is in its initial state, and the drive unit 1080 of the electronic imaging device 100 is still in an inclined state, as shown in the figure. Figure 132a As shown, the telescopic rod X43 is also in the retracted state at this time. This structural diagram can also be used to describe the process changes when removing the processing box 1 from the electronic imaging device. When the door cover 101 is opened, the pushing part 102 no longer pushes the push rod X41. As the first elastic member X41a recovers its elastic deformation, the push rod X41 returns to its original position. At the same time, the connecting member X42 drives the telescopic rod X43 to return to its original position, and the elastic deformation of the second spring member X43a recovers, making the telescopic rod X43 more effectively return to its original position. Since the front end of the telescopic rod X43 no longer presses the inclined part 1080c of the drive unit 1080, the drive unit 1080 returns to its inclined state.

[0563] Figure 132b This is a schematic diagram showing the state of the pressing component and the drive unit of the electronic imaging device when the processing box is in the correct position in Embodiment 24. When the door cover 101 is closed, the pushing part 102 acts on the push rod X41 of the processing box 1, causing the push rod X41 to move forward, compressing the first spring X41a, and simultaneously driving the connecting part X42 to move. The telescopic rod X43 connected to the connecting part X42 is subjected to tension and begins to slide outward along the cut of the mounting part X51b, while simultaneously stretching and deforming the spring. When the front end of the telescopic rod X43 presses against the inclined part X1080c of the drive unit 1080, the drive unit 1080 is corrected by 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 a centered state. In this embodiment, when the drive unit 1080 is in the centered state, the gear portion 1080a of the drive unit 1080 meshes with the power receiving unit 21, and the power receiving unit 21 transmits the driving force to the photosensitive drum through 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 centered component does not undergo any displacement relative to the rotation center axis of the photosensitive drum.

[0564] Example 25

[0565] like Figures 133 to 137 As shown, this embodiment provides another pressing component Y40 in the processing box 1. The pressing component Y40 is connected to the box body via an elastic component Y60 and is located at the same end of the box body as the power receiving unit 21. The front end of the pressing component Y40 (in the installation direction of the processing box 1) also has a guide surface Y41 (sloping or curved surface) facing downwards. Specifically, one end of the elastic component Y60 is fixed to the bracket Y51, and the other end is fixed to the pressing component Y40, so that the pressing component Y40 can return to its initial state after the external force is removed. Optionally, the elastic component Y60 can be a torsion spring or a tension spring. Further, one end of the pressing component Y40 is sleeved on the photosensitive drum 20, so that the pressing component Y40 can rotate around the axis of the photosensitive drum 20. During the rotation of the pressing component Y40, at least a portion of the structure of the pressing component Y40 does not change distance from the axis of the photosensitive drum.

[0566] like Figure 133 and Figure 134 As shown, when the processing box 1 is installed into the electronic imaging device along the Y1 direction, the pressing member Y40 interferes with the driving unit protective cover 1081 located above the driving unit 1080 in the electronic imaging device. This causes the pressing member Y40 to move in the opposite direction to the Y1 direction under the force of the driving unit protective cover 1081, thereby squeezing the elastic member Y60. At the same time, the side end of the processing box moves upward at this location, causing the processing box to tilt. Figure 135 As shown, as the processing box 1 continues to be installed, the pressing component Y40 moves upward past 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 component Y40 abuts against the drive unit protective cover 1081. Under the guidance of the guide surface Y41, the pressing component Y40 is smoothly inserted into the opening of the drive unit protective cover 1081 and contacts the drive unit 1080. As the front end of the processing box 1 moves downward, it drives the pressing component Y40 to move downward. At this time, the front end of the pressing component Y40 presses down on the drive unit 1080, causing it to move downward and be 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.

[0567] When the processing cartridge is finished and needs to be removed from the electronic imaging device, the user may optionally first press down the handle Y70 of the processing cartridge (e.g., ...). Figure 136 (In the counter-clockwise direction indicated by the arrow in the image), the processing box rotates counter-clockwise around the photosensitive drum 20, and the pressing component Y40, which is fixed relative to the processing box, also moves accordingly. This allows the pressing component Y40 to successfully detach from the drive unit protective cover 1081, avoiding interference. Figure 137 As shown, continue pulling the processing box out in the opposite direction to the installation direction until the processing box is successfully removed from the electronic imaging device.

[0568] Example 26

[0569] Figure 138 This is a schematic diagram of the processing box in Example 26. Figure 138 As shown, the processing cartridge 1 includes a cartridge body Z50, a photosensitive drum 20, a developing roller 30, a pressing component Z40, and a support 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, which receives 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, which receives the output driving force from the driving unit to rotate the developing roller 30.

[0570] Specifically, the bracket Z51 includes a fixing post Z511, and the pressing member Z40 is mounted on the bracket Z51 via the fixing post Z511. Simultaneously, at least a portion of the pressing member Z40 is located inside the outer peripheral surface of the photosensitive drum 20 along its axial direction. During the contact 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 aligning 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, during the engagement between the power receiving unit and the drive unit, the pressing member is at least partially always located within the first planar region. It is not limited to the materials and structures of this application, wherein the projection of the first planar region at least partially coincides with the projection of the photosensitive drum.

[0571] Figure 139 This is a schematic diagram of the drive unit in an electronic imaging device. Figure 139 As shown, the drive unit 1080 includes a gear part 1080a and a drive output part 1080b. During the contact and engagement between the power receiving unit and the drive unit of the electronic imaging device, while the drive unit 1080 of the electronic imaging device engages with the power receiving unit 21, the gear part 1080a engages with the developing roller gear 31 of the processing box 1.

[0572] Figures 140-142 This is a schematic diagram of the processing box in Embodiment 26 where the power receiving unit and the drive unit of the electronic imaging device are not in contact or engaged. Figures 140-142 As shown, when the processing box 1 is installed into the electronic imaging device, the pressing member Z40 mounted on the bracket also gradually moves closer to the drive unit 1080 as the processing box moves. At this time, due to the constraint of the structure of the electronic imaging device (structure not shown), the pressing member Z40 has an upward lifting state, such as... Figure 140 As shown, the pressing component Z40 is currently positioned away from the axis of the power receiving unit 21. Figure 141 As shown, the pressing component Z40 is in a state of being far away from the driving unit 1080, and the driving unit 1080 is still in a tilted state, as... Figure 142 As shown, when the drive unit is not aligned, the axis L1 of the drive unit 1080 is not parallel to the axis 2 of the photosensitive drum 20. Specifically, the drive output part 1080b of the drive unit 1080 is not aligned with the power receiving unit, that is, the power receiving unit of the processing box and the drive unit of the electronic imaging device are not in contact or engaged.

[0573] Figures 143-145 This is a schematic diagram of the processing box in Embodiment 26, showing the contact engagement between the power receiving unit and the drive unit of the electronic imaging device. When the pressing member Z40 contacts the drive unit 1080 and forms structural interference, the pressing member Z40 applies a straightening force to the drive output section 1080b. After receiving the straightening force, the drive unit 1080 moves in a direction closer to the power receiving unit 21. The pressing member Z40 is in a downward state, pressing the drive unit 1080 to straighten it, as shown below. Figure 143 As shown, the pressing component Z40 is positioned close to the axis of the power receiving unit 21 at this time. Figure 144 As shown, the pressing component Z40 and the driving unit 1080 are in a close proximity state, and the driving unit 1080 is in a centered state, as... 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 coaxial. Specifically, the drive output portion 1080b of the drive unit 1080 is aligned with the power receiving unit 21, that is, the power receiving unit and the drive unit of the electronic imaging device are in contact and engaged, so that the drive unit 1080 transmits the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate. At the same time, the gear portion 1080a of the drive unit 1080 is aligned and engaged with the developing roller gear 31, thereby transmitting the driving force to the developing roller gear, so that the developing roller 30 rotates.

[0574] Figure 146This is a diagram showing the states of the pressing component in the contact and non-contact positions in Example 26. Figure 146 As shown, the dashed line of the pressing member Z40 indicates that when the processing box 1 is inserted into the electronic imaging device, the pressing member Z40 is in an upward-raised state due to the structural constraint of the electronic imaging device (structure not shown), meaning that the power receiving unit of the processing box and the drive unit of the electronic imaging device are not in contact or engaged. The solid line of the pressing member Z40 indicates that the pressing member Z40 is in contact with the drive unit 1080, forming structural interference, and the pressing member Z40 presses down on the drive unit 1080 to align it, meaning that the power receiving unit 21 and the drive unit 1080 of the electronic imaging device are in a contact and engaged 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 engaged state, part of the pressing member Z40 is located inside the projected cross-section of the outer peripheral surface of the photosensitive drum 20, that is, part of the pressing member Z40 is located closer to the axis of the photosensitive drum 20.

[0575] Example 27

[0576] Figure 147 This is a schematic diagram of the electronic imaging device in Example 27. Figure 147 As shown, there is an electronic imaging device 100, in which a processing box 1 is detachably housed. The electronic imaging device 100 includes an openable and closable door cover 101, a pusher 102 that is linked to the door cover 101, and a drive unit (not shown in the figure), which is a drive force output component.

[0577] Figure 148 This is a schematic diagram of the processing box in Example 27; Figure 149 This is another schematic diagram of the structure of the processing box in Example 27. (See attached diagram.) Figure 148 , Figure 149 As shown, the processing cartridge 1 includes a cartridge body AA50, a photosensitive drum 20, a developing roller 30, a support AA51, a power receiving unit 21, and a pressing member AA40. The photosensitive drum 20 and the developing roller 30 are rotatably mounted on the cartridge body AA50, and the support AA51 is located at the end of the cartridge body AA50. The pressing member AA40 is used to engage with the drive unit 1080 to align the drive unit. The power receiving unit 21 is used to receive the driving force output by the drive unit in the electronic imaging device. The cartridge body AA50 contains developer.

[0578] Figure 150 This is a partial view of the photosensitive drum and developing roller in Example 27. Specifically, as shown... Figure 150As shown, the power receiving unit 21 is disposed at the end of the developing roller and meshes with the drive unit of the electro-imaging device to receive the driving force output by it, thereby causing the developing roller 30 to rotate. Furthermore, an intermediate gear AA32 is disposed on the developing roller 30, and a photosensitive drum gear AA211 is disposed at the end of the photosensitive drum 20. The photosensitive drum gear AA211 meshes with the intermediate gear AA32 to receive the driving force, thereby enabling the photosensitive drum 20 to rotate. In this embodiment, the power receiving unit is a developing roller gear.

[0579] Figure 151 This is a partial view of the bracket in Example 27. Figure 151-Figure 1 As shown in Figure 53, the bracket AA51 is disposed at one end of the housing AA50 for mounting the pressing component AA40. Further, the bracket AA51 includes a slide groove AA51a and a mounting part AA51b. The pressing component AA40 includes a push rod AA41, a connector AA42, and a swing rod AA43. The push rod AA41 is movably mounted in the slide groove AA51a, and the swing rod AA43 is rotatably disposed in the mounting part AA51b. The push rod AA41 is connected to the swing rod AA43 via the connector AA42. The push rod AA41 can drive the swing rod AA43 to swing, so that the position of the driving unit can be aligned in the first planar area. On the plane perpendicular to the axis of the photosensitive drum, the projection of the first planar area at least partially coincides with the projection of the photosensitive drum.

[0580] Figure 152 This is a partial view of the pendulum rod in Example 27. Figure 152 As shown, the swing arm AA43 includes a first connecting part AA43a, a second connecting part AA43b, and an abutting part AA43c. The first connecting part AA43a is connected to the mounting part AA51b of the bracket AA51, the second connecting part AA43b is connected to one end of the connector AA42, and the abutting part AA43c can achieve the alignment of the drive unit 1080 during movement.

[0581] Figure 153a This is a schematic diagram of the pressing component of the processing box being mounted on the bracket in Example 27; Figure 153b This is another schematic diagram showing the pressing element of the processing box mounted on the bracket in Embodiment 27. (See diagram below.) Figure 153a As shown, the processing box also includes a first connecting part AA43a. The first connecting part AA43a of the swing arm AA43 is mounted on the bracket AA51. One of the second connecting parts AA43b is connected to the inner wall of the mounting part AA51b via a first elastic member AA51a. The first elastic member AA51a can reset the swing arm AA43, that is, allow the swing arm AA43 to return from the corrected position to the initial position. Figure 153bAs shown, the processing box also includes a second elastic element AA42, and another second connecting part AA43b is connected to one end of the connecting element AA42. The connecting element AA42 is connected to the push rod AA41 via the second elastic element AA42a. The second elastic element AA42a serves as a buffer to prevent the push rod AA41 from exerting excessive force and affecting the alignment. In the embodiment, the push rod AA41, the connecting element AA42, and the swing rod AA43 are connected to form a pressing element AA40. The movement and change process of the pressing element AA40 will be described in detail later.

[0582] Figure 154a This is a schematic diagram showing the state of the pressing member and the drive unit of the electronic imaging device when the processing box 1 is in its initial position in Embodiment 27. When the processing box 1 is installed into the electronic imaging device (not shown), the door cover 101 of the electronic imaging device is not yet closed. At this time, the pressing member AA40 of the processing box 1 is in its initial state, and the drive unit 1080 of the electronic imaging device 100 is still in an inclined state, as shown below. Figure 154a As shown, the lever AA43 is also tilted at this time.

[0583] Figure 154b This is a schematic diagram showing the state of the pressing component and the driving unit of the electronic imaging device when the processing box is in the correct position in Embodiment 27. When the door cover 101 is closed, the pushing part 102 acts on the push rod AA41 of the processing box 1, and the push rod AA41 moves forward, driving the connecting part AA42 to move. At this time, the swing rod AA43 connected to the connecting part AA42 is subjected to a pulling force and begins to extend outward. When the abutting part AA43c abuts against the recess 1080a of the driving unit 1080, the driving unit 1080 is corrected by the movement of the swing rod AA43. Figure 154b As shown, the drive unit 1080 is perpendicular to the bracket AA51, i.e., in a centered state. In this embodiment, when the drive unit 1080 is in the centered state, the gear portion 1080b of the drive unit meshes with the power receiving unit 21, and the power receiving unit 21 transmits the driving force to the photosensitive drum through the intermediate gear AA32 and the photosensitive drum gear AA211. It should be noted that during the meshing process between the power receiving unit 21 and the drive unit 1080, the pressing member AA40 is partially located inside the projected cross-section of the outer peripheral surface of the photosensitive drum 20.

[0584] Example 28

[0585] This embodiment provides a processing box structure. Compared to embodiments twenty-two and twenty-three, this embodiment does not include a control mechanism on the processing box. (Refer to...) Figure 154cAs shown, specifically, the processing 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 at one end of the developing roller 30 meshes with the gear at one end of the photosensitive drum 20. When the processing cartridge is installed in the electro-imaging device, the first gear CC32 abuts against the gear portion 1080a of the drive unit of the electro-imaging device, so that the developing roller 30 meshes with the gear portion 1080a of the drive unit via the first gear CC32. Thus, through the meshing of the two, the drive unit of the electro-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 having to move the drive unit of the electro-imaging device from the initial tilted state to a position where its axis is substantially parallel or coaxial with the axis of the photosensitive drum. In particular, 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 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 (e.g., Figure 154c Preferably, its upper teeth are designed as helical teeth to better adapt to meshing with the helical teeth of the drive unit of the electronic imaging device.

[0587] In this embodiment, the power receiving unit located at the end of the photosensitive drum does not need to mesh with the drive unit of the electro-imaging device, so the structure of this power receiving unit can also be eliminated. In this case, at either the drive end or the non-drive end, by setting mutually cooperating transmission gears at the ends of the photosensitive drum and the developing roller, the photosensitive drum can mesh with the developing roller, so that the photosensitive drum can receive the driving force output from the drive unit of the electro-imaging device received by the first gear via the developing roller. Further, the processing box also includes a second gear 31 and a third gear CC211. The second gear 31 is disposed at one end of the developing roller 30, and the third gear CC211 is disposed at one end of the photosensitive drum 20, and the third gear CC211 meshes 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.

[0588] In another embodiment, a first gear CC32 is disposed at one end of the photosensitive drum 20, enabling the photosensitive drum to receive the driving force output by 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 processing cartridge is installed in the electro-imaging device, the photosensitive drum engages with the drive unit in the electro-imaging device via the first gear, so that the photosensitive drum and the developing roller can receive the driving force output by the electro-imaging device.

[0589] Example 29

[0590] Figure 155 This is a schematic diagram of the processing box in Example 29. Figure 156 This is a partial schematic diagram of the first gear in Example 29. (As shown...) Figure 155 , Figure 156 As shown, the processing cartridge 1 includes a cartridge body CC50, a photosensitive drum 20, a developing roller 30, a pressing element CC40, a power receiving unit 21, a first gear CC32, and the cartridge body CC50. The cartridge body CC50 contains developer and includes a support CC51. The photosensitive drum 20 and the developing roller 30 are rotatably mounted on the cartridge body CC50. The power receiving unit 21 is located at one end of the photosensitive drum 20 and has a power receiving section CC21a for receiving the driving force output by the electronic imaging device drive unit 1080, thereby causing the photosensitive drum 20 to rotate. The first gear CC32 is disposed at the end of the developing roller 30 and is located at the same end of the housing CC50 as the power receiving unit 21. It is used to mesh with the gear part of the drive unit 1080 of the electronic imaging device, thereby driving the drive unit 1080 to move toward the power receiving unit 21 so that the drive unit 1080 can contact and mesh with the power receiving unit 21. 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.

[0591] Furthermore, the pressing component CC40 is fixedly mounted on the bracket CC51 and located at the same end of the housing CC50 as the power receiving unit 21. In the projection plane along the axial direction of the photosensitive drum, at least a portion of the pressing component CC40 is located inside the projection section along 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 component CC40 is located inside the photosensitive drum 20. The pressing component CC40 includes a pressing part, which refers to the part of the pressing component CC40 that contacts the drive unit. During the contact and engagement process between the power receiving unit 21 and the drive unit of the electronic imaging device, the pressing component CC40 can contact the drive unit 1080 to achieve the alignment of the drive unit. That is, the driving unit of the electronic imaging device can be aligned by the pressing component CC40. Aligning the position of the drive unit means making the axis of the drive unit substantially parallel or coaxial with the axis of the photosensitive drum.

[0592] In this embodiment, the pressing component CC40 and the bracket are integrally formed. It can be understood that in other embodiments, the pressing component may be fixed to the bracket via a movable connection. The pressing component CC40 allows the drive unit 1080 to move between an inclined position and a straightened position. Specifically, when the processing cartridge is initially installed into the electronic imaging device, the drive unit 1080 is inclined relative to the photosensitive drum axis, and the pressing part of the pressing component CC40 abuts against the drive unit 1080. As the processing cartridge continues to be installed, the pressing part of the pressing component CC40 applies a force to the drive unit 1080, causing the drive unit 1080 to reach the straightened position, and causing the pressing component CC40 to have a certain displacement relative to the photosensitive drum.

[0593] Continue to refer to Figure 156 As shown, the first gear CC32 has a protrusion CC32a, which is spirally distributed. When the drive unit 1080 of the electronic imaging device meshes with the first gear CC32, the first gear CC32 can drive the drive unit 1080 to move toward the power receiving unit 21, so that the drive unit 1080 of the electronic imaging device and the power receiving unit 21 come into contact and mesh.

[0594] Figure 157 This is a schematic diagram of the drive unit in an electronic imaging device. Figure 157 As shown, the drive unit 1080 of the electronic imaging device includes a gear section 1080a, a small diameter section 1080b, and a drive output section 1080c. During the process of the gear section 1080a meshing and rotating with the first gear CC32 of the processing box 1, the power receiving unit 21 contacts and meshes with the drive output section 1080c of the drive unit 1080.

[0595] Figure 158a This is a schematic diagram of the processing box in Example 29, where the photosensitive drum power receiving unit and the drive unit in the electronic imaging device are not in contact or engaged. Figure 158a As shown, the processing box 1 also 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 mesh, so that the driving force received by the power receiving unit 21 from the driving unit 1080 of the electronic imaging device can be transmitted to the third gear CC211, and then the third gear CC211 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.

[0596] During the installation of the processing box 1 into the electronic imaging device, initially, the pressing component CC40 mounted on the bracket gradually moves closer to the drive unit 1080 of the electronic imaging device as the processing box moves, but does not contact the small-diameter portion of the drive unit 1080. Figure 158a As shown, at this time, the pressing component CC40 is far from the drive unit 1080, the drive unit 1080 is still tilted, 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 is not 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 processing box and the drive unit 1080 of the electronic imaging device are not in contact or meshing.

[0597] During continued installation, when the pressing component CC40 contacts the drive unit 1080 of the electronic imaging device, forming structural interference, the pressing component CC40 applies a balancing force to the drive unit 1080. The pressing component CC40 is in a downward position, pressing the drive unit 1080 to align it. 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 upright state. In the upright state of the driving unit 1080, the axis L1 of the driving unit 1080 and the axis L2 of the photosensitive drum 20 are in a parallel state, or in other words, in a coaxial state. In this state, the gear part 1080a of the driving unit 1080 meshes with the first gear CC32. Since the gear part 1080a of the driving unit 1080 is helical, and the protrusion CC32a of the first gear CC32 is also spirally distributed, the driving unit 1080 moves in the direction close to the power receiving unit 21 when the driving unit 1080 and the first gear CC32 are meshing and rotating.

[0598] Specifically, the drive output portion 1080c of the drive unit 1080 of the electronic imaging device is aligned with the power receiving portion CC21a of the power receiving unit 21, that is, the power receiving unit and the drive unit are in contact and engaged, so that the drive 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, so as to realize the rotation of the developing roller 30.

[0599] Figure 159 This is a schematic diagram showing the force exerted on the drive unit in contact with the first gear in the electronic imaging device of Embodiment 29. Figure 159As shown, when the drive unit 1080 of the electronic imaging device and the first gear CC32 are in a meshing and rotating state, the meshing of the helical teeth of the gear portion 1080a of the drive unit 1080 and the protrusion CC32a of the first gear CC32 generates an axial force F1. Under the action of the axial force F1, the drive unit 1080 tends to move towards the side closer to the power receiving unit 21, that is, the drive 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 an axial force F2 due to meshing, causing the first gear CC32 to tend to move away from the power receiving unit 21. However, due to the constraint of the processing box 1 structure, the first gear CC32 will not move axially.

[0600] Example 30

[0601] This 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 disposed outside the driving unit.

[0602] The electronic imaging device can be a printer, copier, or multifunction scanner / copier, etc., and is not limited here. The following explanation uses a printer as an example. The processing cartridge can be a toner cartridge, ink cartridge, etc.

[0603] Figure 160 This is a schematic diagram of the electronic imaging device provided in the embodiments of this application before the installation of the pressing component. Figure 161a for Figure 160 A magnified view of a portion of region A shown.

[0604] like Figure 160 and Figure 161a As shown, the drive unit protective cover 1081 covers the drive unit 1080. Before the pressing component is installed, the drive unit 1080 is supported by the drive head pusher (not shown) in the electronic imaging device and is in an inclined state. The rotation axis L1 of the drive unit 1080 forms an angle α with the central axis L2 of the drive unit protective cover 1081.

[0605] Figure 161b This is a schematic diagram of the processing box provided in an embodiment of this application. Figure 3 As shown, the processing cartridge 1 includes a cartridge body A10, a photosensitive drum 20, a developing roller 30, a support A11, and a power receiving unit 21, wherein the cartridge body A10 contains developer. The power receiving unit 21 is disposed at one end of the photosensitive drum 20. The power receiving unit 21 is connected to the drive unit 1080 for transmission. In this embodiment, the power receiving unit 21 engages with the drive unit 1080 to receive the driving force of the drive unit.

[0606] In this application, the end of the processing box with the power receiving unit is defined as the driving end, and the end of the processing box 1 with the conductive unit (not shown) is defined as the power end.

[0607] Specifically, 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 exposed outside the through hole A112 to receive the driving force of the drive unit (i.e., drive unit) 1080 of the electronic imaging device (not shown in the figure). In addition, the first fixing post A111 is arranged above and / or in front of the power receiving unit 21 relative to the axial direction of the photosensitive drum 20.

[0608] In order to change the drive unit 1080 of the electronic imaging device from an initial tilted state to a horizontal state capable of engaging with the power receiving unit 21, this application embodiment provides a pressing member for the electronic imaging device, which is used in conjunction with the processing box. The pressing member is detachably installed in the electronic imaging device and can be used alone in the electronic imaging device, or it can work in the electronic imaging device in conjunction with processing boxes of different structures.

[0609] Figure 162 This is a schematic diagram of the structure of the pressing component provided in the embodiments of this application, as shown below. Figure 162 As shown, the pressure member DD40 is independently and detachably mounted on the drive unit protective cover 1081. The pressure member DD40 includes a first main body portion DD41, a deformable portion DD42 connected to the first main body portion DD41, and a pressure portion DD44.

[0610] In some embodiments, the overall shape of the pressing component DD40 may be a circular ring-shaped sheet. In other embodiments, the pressing component DD40 may also be of other shapes, as long as it does not hinder the installation and operation of the processing box. Furthermore, the various structures included in the pressing component DD40 may be integrally formed, or they may be connected into one piece by snap-fit ​​structures, welding, or other connection methods, which are not limited here.

[0611] The drive unit protective cover 1081 has an arc-shaped sidewall, and the first main body DD41 of the pressing member DD40 is in the shape of a circular ring, and the first main body DD41 can cooperate and abut against the sidewall of the drive unit protective cover 1081. The first main body DD41 can be made of thin sheet metal or plastic. This application does not limit its material, as long as it does not affect its installation and the deformation and recovery of the deformable part DD42.

[0612] The deformable part DD42 is connected to the first main body part DD41. When the pressing member DD40 abuts against the drive unit 1080, the deformable part DD42 can deform and drive the drive unit 1080 from an inclined state to a straight state. It should be noted that when the drive unit 1080 is in the straight state in this application, the rotation axis L1 of the drive unit 1080 and the central axis L2 of the drive unit protective cover 1081 are basically coincident, that is, the included angle α is zero or close to zero.

[0613] In this embodiment, the deformable portion DD42 is an arc-shaped elastic sheet. The deformation of the deformable portion DD42 can be achieved by utilizing its own flexible force, or by providing an elastic element on the pressing member DD40. The elastic element can be a component such as a spring or a magnet with a certain elastic force (capable of driving the drive unit 1080 to be upright). Exemplarily, the elastic element 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.

[0614] The deformable part DD42 is connected to the pressing part DD44, and the pressing member DD40 contacts the driving unit 1080 through the pressing part DD44. Specifically, the pressing part DD44 can be a surface structure or a line structure provided on the deformable part DD42. For example, the pressing part DD44 can be an arc-shaped surface protruding towards the driving unit 1080.

[0615] In practical applications, the pressing member DD40 abuts against the driving unit 1080 via the pressing part DD44, causing the driving unit 1080 to adjust from an inclined state to a straight state. When the pressing part DD44 of the pressing member DD40 abuts against the driving unit 1080, the deformable part DD42 deforms. Under the deformation force of the deformable part DD42, the pressing member DD40 drives the driving unit 1080 to adjust from an inclined state to a straight state, and the deformation of the deformable part DD42 recovers.

[0616] In some embodiments, the pressing member DD40 further includes an abutment portion DD43 located at the end of the deformable portion DD42 away from the first main body portion DD41. Specifically, the abutment portion DD43 can be formed by bending from one end of the deformable portion DD42. The abutment portion DD43 can abut against the drive unit protective cover 1081.

[0617] When the drive unit 1080 is in the upright position, the abutment part DD43 abuts against the drive unit protective cover 1081, thereby preventing the pressing part DD44 from contacting the drive unit 1080. This ensures that the drive unit 1080 does not rub against or interfere with the pressing part DD40 during rotation. Therefore, the pressing part DD40 provided in this application does not affect the rotation of the drive unit 1080 and avoids frictional damage between the pressing part DD40 and the drive unit 1080, thus improving the service life of the pressing part DD40.

[0618] To improve the installation stability of the pressure component DD40 and the drive unit protective cover 1081, such as Figure 162 As shown, the pressing component DD40 also includes a fixing part, and the pressing component DD40 is detachably mounted on the drive unit protective cover through the fixing part.

[0619] Specifically, the fixing part includes a first fixing end DD45 and a second fixing end DD46 formed by bending along both ends of the first main body part DD41. The pressing member DD40 is engaged with 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 a hook structure.

[0620] Figure 163 A schematic diagram of the structure of the electronic imaging device provided in this application after the pressure component has been installed. Figure 164 for Figure 163 A magnified view of a portion of region B shown. Figure 165 This is a schematic diagram of the assembly structure between the pressing component 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.

[0621] In this embodiment, both the first fixed end DD45 and the second fixed end DD46 are hook structures, which are detachably connected to the drive unit protective cover 1081 through the hook structure, making installation and replacement convenient.

[0622] To further improve the stability of the overall structure, the first end wall 10811 and the second end wall 10812 may be provided with retaining ribs. Correspondingly, the first fixed end DD45 and the second fixed end DD46 may be provided with protrusions or grooves to make the snap-fit ​​connection more stable.

[0623] In other embodiments, the first end wall 10811 and the second end wall 10812 may also be walls extending axially from the drive unit protective cover 1081, or other optional side walls, which are not limited here. The fixing of the pressing member DD40 on the drive unit protective cover 1081 along the axis L2 is not limited. For example, it can be achieved by adjusting the width of the first main body portion DD41 of the pressing member DD40 to fit tightly with the axial dimension of the drive unit protective cover 1081, thus preventing axial wobbling of the pressing member DD40 on the drive unit protective cover 1081.

[0624] like Figure 163 and Figure 164 As shown, before the pressure component DD40 is installed into the printer separately, the printer door is open and the drive unit 1080 is tilted and will not be straightened by external force. At this time, the pressure component DD40 can be manually installed onto the drive unit protective cover 1081.

[0625] like Figure 163 and Figure 165 As shown, the pressing component DD40 is moved along... Figure 163 The material is fed into the printer in the direction of the middle arrow M. When it contacts the top of the drive unit protective cover 1081, a certain pressing force is applied to the pressing member DD40 to engage the first fixed end DD45 with the first end wall 10811 of the drive unit protective cover 1081, and to engage the second fixed end DD46 with the second end wall 10812 of the drive unit protective cover 1081. Figure 164 As shown, the pressing member DD40 contacts the drive unit 1080 through the pressing part DD44. Since the door cover is not closed, the pressing member DD40 abuts against the drive unit 1080 in an inclined state. Since the part of the drive unit 1080 that is tilted and offset from the periphery of the drive unit protective cover 1081 abuts against the pressing part DD44, the deformable part DD42 adaptably deforms and maintains this deformed state. At this time, the deformation restoring force generated by the deformation of the deformable part DD42 is continuously 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 inclined state to the upright state.

[0626] Furthermore, to facilitate installation and assembly with the processing box, the processing box provided in this application also includes a box pressing member AB40, which is disposed at one end of the processing box.

[0627] Figure 166 This is a partial structural diagram of the printer provided in an embodiment of this application. Figure 167 for Figure 166 A magnified view of a portion of region C shown. Figure 168 This is a schematic diagram of the processing box provided in an embodiment of this application. Figures 166-168 As shown, the processing box provided in this application can be any processing box capable of cooperating with the pressing component, and this application does not limit the specific structure of the processing box. For example... 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. Therefore, the pressing member in this embodiment has universal applicability in its cooperation with the processing box.

[0628] Specifically, when Figure 168 The processing cartridge is installed into the printer, and its installation direction can be the same as that of the aforementioned pressing component DD40, that is, it is fed into the electro-imaging device in the direction of arrow M, as shown below. Figure 166 and Figure 167 As shown, after installation, the processing box is located at the position of the pressing member DD40. The box pressing member AB40 on it can be directly above the pressing member DD40, for example, overlapping the pressing member DD40. At this time, since the thickness of the pressing member DD40 in the direction of the vertical axis L2 in this embodiment is small enough, the pressing member DD40 will not affect the box pressing member AB40 and its function on the processing box, that is, it can be applied to processing boxes with various structures.

[0629] Furthermore, describe the state of the processing box during operation, such as... Figure 169 As shown, when the printer door is closed, the drive unit 1080 enters a state where it can be swung by external force. The deformation-restoring force of the deformable part DD42 applied to the drive unit 1080 then moves the drive unit 1080 from a tilted state to a straightened state. As the drive unit 1080 straightens, the photosensitive drum power receiver head (not shown) on the processing cartridge gradually engages well with the drive unit 1080. At this time, the restoration of the deformable part DD42 causes the abutment part DD43 to move to abut against the drive unit protective cover 1081, thereby preventing the pressing part DD44 from contacting the drive unit 1080. This prevents the drive unit 1080 from rubbing against or interfering with the pressing part DD40 during rotation. This is the second state of the pressing part DD40, and normal printing can then proceed.

[0630] Example 31

[0631] This embodiment also provides a compression component, which is a further improvement on the basis of embodiment 30. The parts not described are the same as those in the foregoing embodiments, and will not be repeated for the sake of simplicity.

[0632] Figure 170 This is a schematic diagram of the structure of the compression assembly provided in the embodiments of this application, as shown below. Figure 170 As shown, the compression assembly EE90 of this embodiment can be independently and detachably installed on the drive unit protective cover 1081. The compression assembly EE90 includes a frame EE91 and a compression member EE40 connected to the frame EE91.

[0633] In some embodiments, along the length 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 receiving cavity of the electronic imaging device.

[0634] To facilitate the installation of the compression assembly E90, the compression assembly EE90 is adapted to the width of the processing cartridge receiving cavity within the printer body. When the compression assembly EE90 is installed inside 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 processing cartridge receiving cavity of the electro-imaging device (e.g., the printer). In some embodiments, the frame can be mounted on the corresponding structures of the two end walls of the printer's processing cartridge receiving cavity.

[0635] Specifically, the structure of the pressure component EE40 is the same as that of the pressure component DD40 described in Embodiment 1, and it is installed on the drive unit protective cover 1081 located inside the printer body in the same way, which will not be described again here.

[0636] In this design, the first end EE92 of the frame EE91 is bent to form the first fixing part EE921, and the second end EE93 of the frame EE91 is bent to form the second fixing part EE931. The first fixing part EE921 (first end) and the second fixing part EE931 (second end) can be stepped. In some embodiments, the frame EE91 can be a plastic part, a sheet metal part, or a deformable component. Its thickness is preferably not conducive to the installation of the processing box and its coexistence with the processing box. When a deformable component is selected, it can avoid obstructing the installation of the processing box without affecting its operation.

[0637] The first end EE92 of the frame EE91 can be connected to the pressing member EE40 via the first fixing part EE921. The second end EE93 of the frame EE91 can be detachably connected to the connecting structure on the end wall of the electronic imaging device via the second fixing part EE931. The connecting structure can be a guide rail, a side wall step, or other similar structure. For example, the connection method between the second fixing part EE931 and the connecting structure can be snap-fit, abutment, or insertion, etc., and is not limited here.

[0638] Understandably, by setting the frame EE91, the installation of the pressure assembly EE90 can be quickly and accurately positioned, eliminating the need for careful pre-positioning to complete the installation of the pressure component EE40. This greatly increases the convenience of installing the pressure component EE40, especially for users. Furthermore, when it is necessary to replace the processing cartridge or remove and reinstall it, the pressure assembly EE90 occupies a certain length of space, making it easy to identify whether the pressure assembly EE90 / pressure component EE40 has been pre-installed in the printer, providing a clear prompt to the user.

[0639] According to the pressing assembly provided in this application, the pressing component can be detachably installed in the printer independently, or it can be detachably installed in the printer together with the frame. When the pressing component can be detachably installed in the printer independently, the pressing component can be installed into the printer first, followed by the processing box, and then the pressing component can be removed from the printer. This method is applicable, but not limited to, removing the pressing component during the door cover closing operation, and is not limited to simultaneously using other structures on the processing box to adjust the drive unit 1080 from a tilted state to a straightened state.

[0640] Example 32

[0641] This application also provides a pressing component that is detachably installed in a printer. It can be used alone in a printer or work in a printer in conjunction with processing cartridges of different structures.

[0642] As described in Embodiment Thirty, before the pressure component is installed, the drive unit 1080 is supported by the drive head push component in the printer and is in an inclined state, and the rotation axis L1 of the drive unit 1080 forms an angle α with the central axis L2 of the drive unit protective cover 1081.

[0643] Figure 171 Another structural schematic diagram of the compression assembly provided in the embodiments of this application is shown below. Figure 171As shown, the compression assembly FF90 is independently and detachably mounted on the drive unit protective cover 1081. The compression assembly FF90 includes: a second main body FF91, a compression member FF40 mounted on the second main body FF91, and a deformable member FF92. The compression member FF40 is connected to the second main body FF91 via the deformable member FF92, and the compression member FF40 reciprocates under the deformation of the deformable member FF92.

[0644] The second main body FF91 can be made of thinner plastic or sheet metal parts; this application does not restrict its material, as long as it does not affect its installation or the deformation and recovery of the pressing part FF40 and the deformable part FF92. Specifically, the second main body FF91 has positioning structures on both sides, which cooperate with the connecting structures on both sides of the printer. The connecting structures on both sides of the printer can be guide rails, side wall steps, or other structures. When the second main body FF91 is installed on the printer using the positioning structures, the positioning structures engage with the printer's connecting structures.

[0645] Figure 172 This is a schematic diagram of the structure of the compression assembly provided in the embodiments of this application, as shown below. Figure 172 As shown, the second main body FF91 may also be provided with a handle, which is used to facilitate the installation and holding of the compression component.

[0646] Furthermore, at least one end of the second main body FF91 is provided with a positioning structure, and the pressing assembly is detachably installed in the processing box mounting cavity of the electronic imaging device through the positioning structure. Specifically, the end of the second main body FF91 near the pressing component is provided with a first protrusion FF911 and a second protrusion FF912. The first protrusion FF911 and the second protrusion FF912 can serve as the aforementioned positioning structure and be connected with the printer. The connection method can be snap-fit, abutment, plug-in, etc., which are not limited here.

[0647] After the pressing assembly is installed along the guide rails on both sides of the printer, when the pressing component FF40 abuts against the drive unit 1080, the deformable component FF92 deforms, causing the drive unit 1080 to adjust from a tilted state to a straight state. Under the deformation force of the deformable component FF92, the pressing component FF40 causes the drive unit 1080 to adjust from a tilted state to a straight state, and the deformation of the deformable component FF92 recovers.

[0648] In some embodiments, the pressing member FF40 includes an abutting portion FF43 and a pressing portion FF44. The abutting portion FF43 abuts against the drive unit protective cover 1081, and the pressing portion FF44 drives the drive unit 1080 from an inclined 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 coincident, that is, the included angle α is zero or close to zero.

[0649] The deformable component FF92 can be a spring, torsion spring, sheet metal, etc., and is not limited here.

[0650] In this embodiment, the pressing member FF40 is provided with a connecting shaft FF431, and the pressing member FF40 is detachably connected to the second main body FF91 through the connecting shaft FF431. Correspondingly, the second main body FF91 is provided with a limiting hole FF915 that cooperates with the connecting shaft FF431. The deformable member FF92 is sleeved on the connecting shaft FF431. The deformable member FF92 is a torsion spring, which can improve the stability of the pressing member during movement. The pressing member FF40 is connected to the second main body FF91 through the torsion spring. In other embodiments, the deformation of the deformable member FF92 can be generated not only by its own elasticity, but also by providing an elastic member on the pressing member FF40. The elastic member can be a component such as a steel sheet with a certain elasticity or flexibility (which can drive the drive unit 1080 to be upright).

[0651] When the drive unit 1080 is in the upright position, the abutment part FF43 abuts against the drive unit protective cover 1081, thereby preventing the pressing part FF44 from contacting the drive unit 1080. This prevents the drive unit 1080 from rubbing against or interfering with the pressing part FF44 of the pressing part FF40 during rotation. The pressing part FF40 provided in this application does not affect the rotation of the drive unit 1080 and avoids frictional damage between the pressing part FF40 and the drive unit 1080, thus improving the service life of the pressing part FF40.

Figure 174 This is another assembly diagram of the compression assembly and processing box provided in an embodiment of this application. Figure 175 This is another assembly diagram of the compression assembly and processing box provided in the embodiments of this application, as shown below. Figures 173-175 As shown, the pressing assembly provided in this application works in conjunction with the processing cartridge in a printer. The processing cartridge 1 can be a processing cartridge having a structure matching the various embodiments of the pressing assembly FF90 described above. The overall shape of the pressing assembly FF90 is preferably such that it does not hinder the installation, removal, and operation of the processing cartridge.

[0653] like Figure 173 As shown, the driving end of the processing box 1 is provided with a first protrusion FF913 and a second protrusion FF914, and the end of the second main body FF91 near the pressing component FF40 is provided with a first protrusion FF911 and a second protrusion FF912. The protrusions and blocks are matched and connected to each other, so that the pressing component FF90 can be matched and connected to the processing box 1.

[0654] Specifically, if Figures 174-175 As shown, the first protrusion FF911 on the second main body FF91 matches and connects with the first protrusion FF913 on the processing box 1 to form a positioning structure; the second protrusion FF912 on the second main body FF91 matches and connects with the second protrusion FF914 on the processing box 1 to form a positioning structure. The processing box 1 matches and connects with the pressing assembly FF90.

[0655] like Figure 173 As shown, the processing box provided in this embodiment may not have any pressing structure such as a box pressing component, and the pressing component FF40 of the pressing assembly FF90 has universal applicability in its cooperation with the processing box 1. Specifically, when the box is... Figure 174 The processing box 1 is installed into the printer, and its installation direction can be the same as that of the aforementioned pressure assembly FF90, that is, along the direction of arrow M. Figure 69 (As shown) is fed into the printer.

[0656] In some embodiments, the various structures included in the above-mentioned pressing component are preferably integrally formed, which can improve the overall stability.

[0657] The following describes the installation procedure for the compression component FF40 and the processing box 1:

[0658] like Figure 176 As shown, the processing box 1 is first installed in the printer (not shown), and then the pressure member FF40 is installed separately in the printer. Before the pressure member is connected to the processing box, the drive unit 1080 is supported by the drive head pusher in the printer and is in an inclined state, that is, the drive unit 1080 will not be straightened by external force at this time.

[0659] Continue installing the FF90 pressure assembly along both sides of the printer's guide rails until it is fully installed. Figure 177 In the structure shown, the abutting part FF43 of the pressing member FF40 is placed on the drive unit protective cover 1081, and the pressing part FF44 adjusts the drive unit 1080 from an in...
