Description

Technical Field

[0001] The present invention relates to the field of electronic photographic imaging, and in particular to a process box that can be detachably mounted to an electronic photographic imaging device. Background Art

[0002] Existing, the processing box includes a powder bin and a waste powder bin which are combined with each other. The powder bin is used to accommodate the toner required for development. The developing member for carrying the toner is rotatably installed in the powder bin. The waste powder bin is used to accommodate the waste powder generated by development. The photosensitive member for forming an electrostatic latent image is rotatably installed in the waste powder bin. When the processing box is working, the developing member contacts the photosensitive member, and the toner carried by the developing member develops the electrostatic latent image formed on the surface of the photosensitive member.

[0003] When the processing box does not need to work, in order to prevent the developer from being in contact with the photosensitive member for a long time, which may cause the developer to deform or the photosensitive member to be contaminated, the processing box also includes a force-bearing part fixed in the powder bin. Accordingly, the electronic photographic imaging device, such as a printer, is provided with a force-applying part for applying a force to the force-bearing part. When the force-applying part contacts the force-bearing part and applies a force to the force-bearing part, the powder bin rotates relative to the waste powder bin, and the two move away from each other. At the same time, the developer and the photosensitive member are also separated. When the processing box needs to work, the force-applying part no longer applies a force to the force-bearing part, and the powder bin and the waste powder bin move closer to each other. At this time, the developer and the photosensitive member are in contact again.

[0004] The force-applying part applies force to the force-receiving part to force the powder bin and the waste powder bin to move away from each other, so as to prevent the photosensitive part from being contaminated. However, since the force-receiving part is fixedly installed in the powder bin, in order to ensure that the force-receiving part can be combined with the force-applying part, the force-receiving part is arranged to be relatively protruding. When the processing box falls or collides during transportation, the force-receiving part may be broken, thereby making it impossible to separate the developing part and the photosensitive part, resulting in contamination of the photosensitive part. Summary of the invention

[0005] The present invention provides a processing box, in which a movable part for combining with a force applying part is movably provided. The movable part is installed in a movable manner. Even if the processing box falls or collides, the movable part has a certain amount of movement, thereby greatly reducing the chance of the movable part being broken.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A processing box is detachably installed in an imaging device provided with a force-applying portion, and the processing box includes a first unit and a second unit that are combined with each other, and a movable part that can be combined with the force-applying portion and receive the force applied by the force-applying portion; when the processing box is installed to the imaging device, the first unit and the second unit can be switched between states of being close to each other and being separated from each other; the movable part is installed in the processing box in a movable manner; when the movable part is subjected to the force applied by the force-applying portion, the movable part rotates around the axis or at least the part of the movable part that receives the force moves in a straight line; during the movement of the movable part, the movable part forces the first unit and the second unit to separate from each other.

[0008] The first unit includes a developing member rotatably mounted therein, and the second unit includes a photosensitive member rotatably mounted therein. When the first unit and the second unit are close to each other, the developing member and the photosensitive member are in contact. When the first unit and the second unit are separated from each other, the developing member and the photosensitive member are not in contact. A movable member is mounted in the second unit.

[0009] Preferably, the movable member is movably mounted on the photosensitive member, and the movable member moves in a linear direction parallel to a center line connecting the photosensitive member and the developing member when the movable member contacts the developing member.

[0010] Preferably, the direction in which the movable member moves in a straight line is not parallel to the direction in which the force-applying portion moves.

[0011] Specifically, the movable part includes a mounting part and an acting part which are combined with each other, wherein the mounting part is used to mount the movable part in the processing box, and the acting part is used to be combined with the force applying part, and the acting part is movable relative to the mounting part.

[0012] As one of the embodiments, when the process cartridge is mounted to the image forming apparatus, the free end of the movable member is not opposed to the force applying portion.

[0013] Further, the movable member includes a force receiving surface combined with the force applying portion, and when the process box is installed to the image forming device, the force receiving surface does not face upward.

[0014] Preferably, the process cartridge further comprises a retaining member for retaining the movable member at a predetermined force receiving position.

[0015] The second unit contains developer, the first unit contains waste developer, and the movable member is mounted on a rotating member rotatably mounted in the first unit.

[0016] As another embodiment, the length of the action portion is variable. Specifically, the action portion includes a first portion connected to the mounting portion and a second portion connected to the first portion, and at least one of the first portion and the second portion is deformable.

[0017] The movable part is installed in a movable manner that allows rotation or linear motion. Even if the processing box falls or collides, the movable part has a certain amount of movement, thereby greatly reducing the chance of the movable part being broken. BRIEF DESCRIPTION OF THE DRAWINGS

First, the length direction of the processing box 1 is defined as the longitudinal direction X, the width direction is the transverse direction Y, and the installation direction is the vertical direction Z; Figure 1 and Figure 2 The overall structure of the process cartridge 1 will be described.

[0040] Figure 1 is a three-dimensional diagram of a process cartridge according to the present invention; Figure 2 It is a schematic diagram of the exploded view of the processing box involved in the present invention.

[0041] The processing box 1 can be detachably installed to the electronic photographic imaging device, including a first unit 2 and a second unit 3 that are combined with each other and can rotate relative to each other, and a first end cover 4 and a second end cover 5 respectively located at two longitudinal ends, and the first unit 2 and the second unit 3 are combined through the first end cover 4 and the second end cover 5; the first end cover 4 and the second end cover 5 can exist in the form of independent components respectively, or in the form of part of the powder bin 3 or the waste powder bin 2. Furthermore, the direction from the first end cover 4 to the second end cover 5 is the +X direction, and the direction from the powder bin 3 to the waste powder bin 2 is the +Y direction.

[0042] Combination Figure 1 and Figure 2The second unit 3 includes a second unit shell 30 for accommodating developer, a developing member 32 rotatably mounted in the second unit shell 30, a bracket 31 fixedly mounted on the second unit shell 30, and a first power receiving member 33 rotatably supported by the bracket 31; the first power receiving member 33 passes through the second end cover 5 for receiving driving force from the outside, the second unit shell 30 is used to accommodate toner, and thus, the second unit 3 can also be considered as a powder bin, and the second unit shell 30 can also be considered as a powder bin shell; the developing member 32 is rotatably supported by the bracket 31, and includes a rotating shaft 321, a covering layer 322 coated on the circumferential surface of the rotating shaft 321, and a power receiving portion 323 arranged at one longitudinal end of the rotating shaft 321, the power receiving portion 323 receives the driving force of the first power receiving member 33 to drive the developing member 32 to rotate, the covering layer 322 extends along the longitudinal direction of the rotating shaft 321, and in the longitudinal direction, the rotating shaft 321 is not completely covered by the covering layer 322.

[0043] The first unit 2 includes a first unit housing 20 for accommodating waste developer and a photosensitive member 21 rotatably mounted in the first unit housing 20. It is further defined that the end of the process cartridge 1 where the photosensitive member is not mounted points to the end where the photosensitive member is mounted as the +Z direction. The first unit housing 20 is used to accommodate waste powder generated during the development process, so the first unit 2 can also be called a waste powder bin, and the first unit housing 20 can also be called a waste powder bin housing; the photosensitive member 21 includes a photosensitive cylinder 211, a base 213 located at one longitudinal end of the photosensitive cylinder 211, and a second power receiving member 212 mounted on the base 213, the second power receiving member 212 also passes through the second end cover 5 for receiving a driving force from the outside, thereby driving the photosensitive cylinder 211 to rotate; the diameter of the photosensitive cylinder 211 is f1, and the diameter of the base 213 is f2, satisfying f1>f2.

[0044] At the same time, the processing box 1 also includes a compression spring 7 installed between the first unit 2 and the second unit 3. When the processing box 1 is working, the first power receiving member 33 and the second power receiving member 212 respectively receive driving force from the electronic photographic imaging device to drive the developing member 32 and the photosensitive member 21 to rotate. Under the urging force provided by the compression spring 7, the first unit 2 and the second unit 3 are close to each other, and the photosensitive member 21 and the developing member 32 are in contact; when the processing box 1 is not working, the force applying portion 9 (such as Fig. 6A As shown in the figure, the first unit 2 and the second unit 3 rotate relative to each other and separate, and the photosensitive member 21 and the developing member 32 lose contact; of course, the member for forcing the first unit 2 and the second unit 3 to approach each other is not limited to the compression spring 7, for example, it can also be a tension spring installed between the first unit 2 and the second unit 3, or an elastic rubber installed between the first unit 2 and the second unit 3.

[0045] The first power receiving member 33 and the second power receiving member 212 both pass through the second end cover 5. Here, one end of the processing box 1 on which the first power receiving member 33 and the second power receiving member 212 are arranged is called the driving end, and the other end opposite thereto in the longitudinal direction is the non-driving end. Therefore, the first end cover 4 can also be called the non-driving end cover, and the second end cover 5 can also be called the driving end cover; the direction from the non-driving end cover 4 to the driving end cover 5 is the +X direction, the direction from the second unit 3 to the first unit 2 is the +Y direction, and the installation direction of the processing box 1 is the +Z direction; the second unit 3 and the first unit 2 are both combined with the driving end cover 5 and the non-driving end cover 4, thereby realizing the assembly of the processing box 1, wherein the first unit 2, the non-driving end cover 4 and the driving end cover 5 are combined in a fixed installation manner, and the three cannot move relative to each other, and the second unit 3 is movable relative to the aforementioned three, and the specific movement method is that the second unit 3 rotates coaxially with the first power receiving member 33.

[0046] Furthermore, the processing box 1 also includes a movable part 6 arranged therein, and at least a part of the movable part 6 can move between an initial position and a terminal position. When the movable part 6 is in the initial position, the first unit 2 and the second unit 3 are close to each other, and the photosensitive part 21 is in contact with the developing part 32. At this time, the movable part 6 is not subjected to external force and is in a movable state; when the movable part 6 receives the force of the force-applying part 9, it can move from the initial position to the terminal position. When the movable part 6 is in the terminal position, the first unit 2 and the second unit 3 are separated from each other, and the photosensitive part 21 is out of contact with the developing part 32. At this time, the movable part 6 is in an immovable state due to the force of the force-applying part 9; when the force of the force-applying part 9 is withdrawn, as the second unit 3 returns to a position close to the first unit 2, the movable part 6 returns from the terminal position to the initial position, or in other words, the movable part 6 returns from an immovable state to an movable state; the movable part 6 is movable or immovable refers to the movable part 6 relative to its installation position.

[0047] Embodiment 1

[0048] [Active Parts]

[0049] Figure 3 It is a three-dimensional diagram of the movable part involved in the first embodiment of the present invention.

[0050] The movable part 6 includes a main body 61, a force-bearing part 62 connected to the main body 61, and a pushing part 63 connected to the force-bearing part 62. The movable part 6 is movably arranged in the processing box 1 through the main body 61. The force-bearing part 62 is used to receive the force of the force-applying part 9 and transmit the force to the pushing part 63. The pushing part 63 is used to force the first unit 2 and the second unit 3 to separate when the force-bearing part 62 is subjected to the force, and to force the movable part 6 to return from the terminal position to the initial position after the force acting on the force-bearing part 62 is cancelled, or in other words, to force the movable part 6 to return from the inactive state to the active state.

[0051] As shown in the figure, a coupling portion 611 for coupling with a component of the processing box 1 is formed in the main body 61. Preferably, the coupling portion 611 is an elliptical hole having a first long axis end 612 and a second long axis end 613 relative to each other, the length of its long axis is h2, and the length of its short axis is h1; the force-bearing portion 62 protrudes from the main body 61 and is formed with a force receiving surface 621 for receiving the force; the forced pushing portion 63 is a groove connected to the force-bearing portion 62 and recessed in the direction of the coupling hole 611. More preferably, the forced pushing portion 63, the coupling portion 62 and the main body 61 are formed integrally, so that when the movable part 6 is located in the initial position, the movable part 6 is movable as a whole, and when the movable part 6 is located in the terminal position, the movable part 6 is immovable as a whole.

[0052] Figure 4 It is a schematic diagram of the state in which the movable part and the developing part involved in the first embodiment of the present invention are combined.

[0053] As described above, when the force-bearing portion 62 is subjected to a force, the first unit 2 and the second unit 3 are forced to separate. The following description will be made by taking the combination of the movable member 6 and the developing member 32 as an example.

[0054] The processing box 1 also includes a developing gear 324 installed on the power receiving part 323, which is used to receive the driving force. When the movable part 6 is acted upon by the force, the movable part 6 is combined with the rotating shaft 321 located between the developing gear 324 and the covering layer 322, and the rotating shaft 321 is pushed, thereby driving the entire second unit 3 to rotate, and the first unit 2 and the second unit 3 are separated, thereby finally realizing the separation of the developing part 32 and the photosensitive part 21.

[0055] Of course, the movable member 6 can also be combined with other components in the second unit 3, such as a toner supply member 34 ( Figure 2 As shown), generally, the toner supply member has a structure similar to that of the developing member 32, and is also coated with a covering layer on the outer surface of a rotating shaft, and a toner supply member gear for receiving a driving force is installed at one longitudinal end of the toner supply member, the difference is that the material coated by the toner supply member 34 is different from the material coated by the developing member 32, but the materials coated by both are elastic, and the developing member 32 and the toner supply member 34 are collectively referred to as a rotating member, and the rotating member includes a rotating shaft and a covering layer coated on the circumferential outer surface of the rotating shaft, and the movable member 6 is combined with the rotating shaft, and the portion where the movable member 6 is combined with the rotating shaft is located between the driving gear (a collective term for the developing gear 324 and the toner supply member gear) and the covering layer.

[0056] Furthermore, in order to prevent the rotating shaft from slipping off the pushing portion 63 when the movable member 6 applies a pushing force to the rotating shaft, Figure 3As shown, the movable part 6 also includes an ear 64 arranged adjacent to the forced pushing portion 63. Specifically, the ear 64 can be considered as a protrusion extending from the main body 61 or the forced pushing portion 63. Preferably, along the short axis direction of the combining hole 61 or the installation direction of the processing box 1, the ear 64 and the force-bearing portion 62 are respectively located on both sides of the forced pushing portion 62. More preferably, the force-bearing portion 62 is located above the forced pushing portion 63, and the ear 64 is located below the forced pushing portion 63. When the forced pushing portion 63 is combined with the rotating shaft, the ear 64 can support the rotating shaft from the lower part of the rotating shaft.

[0057] [Movement process of moving parts]

[0058] Figure 5A and Figure 5B is a side view of the movable member according to the first embodiment of the present invention when it is not combined with the force applying portion and is viewed along the longitudinal direction of the process cartridge; Fig. 6A and Figure 6B is a side view of the movable member according to the first embodiment of the present invention when combined with the force applying portion and viewed along the longitudinal direction of the process cartridge; Figure 7 It is a simplified schematic diagram of the relative motion between the movable part, the photosensitive part, and the developing part involved in the first embodiment of the present invention.

[0059] like Figure 5A and Figure 5B As shown, the movable part 6 is located in the initial position, at which time the first unit 2 and the second unit 3 are close to each other, the developing part 32 is in contact with the photosensitive part 21, and the movable part 6 is not acted upon by any force, but remains in an active state in which it can be in contact or not in contact with the rotating shaft. Even if the movable part 6 is in contact with the rotating shaft, the movable part 6 will not apply a thrust force to the rotating shaft, and the force receiving surface 621 is opposite to the force applying part 9 located outside the processing box 1.

[0060] like Fig. 6A and Figure 6B As shown, when the force-applying portion 9 moves along the M direction toward the direction of the force-receiving portion 62 and begins to apply a force to the force receiving surface 621, the movable member 6 / forced pushing portion 63 moves toward the direction of the second unit 3. As the movable member 6 moves, the forced pushing portion 63 begins to apply a force to the rotating shaft, and the force is transmitted to the bracket 31 through the rotating shaft, and then transmitted to the second unit housing 30 by the bracket 31, forcing the second unit 3 to move relative to the first unit 2, the first end cover 4 and the second end cover 5 along Figure 5A The developing member 32 and the photosensitive member 21 are rotated in the direction shown by r, and the second unit 3 and the first unit 2 are separated from each other, and finally the developing member 32 and the photosensitive member 21 are separated, and a gap g is formed therebetween, and the movable member 6 reaches the terminal position; when the force-applying portion 9 continuously applies a force to the force-bearing portion 62, the developing member 32 and the photosensitive member 21 remain separated from each other, and the movable member 6 remains immobile under the action of the force, and at the same time, the compression spring 7 located between the first unit 2 and the second unit 3 is compressed.

[0061] When the force applied to the force-bearing portion 62 is removed, under the elastic restoring force of the compression spring 7, the second unit 3 rotates again relative to the first unit 2, the first end cover 4 and the second end cover 5 in the direction opposite to the direction indicated by r, and the second unit 3 returns to Figure 5A and Figure 5B As shown in the state where the developing member 32 is close to the first unit 2, at this time, the developing member 32 is in contact with the photosensitive member 21 again; as the second unit 3 rotates, the pushing portion 63 of the movable member 6 is pushed by the rotating shaft, and drives the movable member 6 to move from the terminal position to the initial position; when the developing member 32 returns to the position in contact with the photosensitive member 21, the movable member 6 returns from the terminal position to the initial position, and at this time, the movable member 6 is in an active state again.

[0062] The process box 1 is installed in an inverted manner to the electrophotographic imaging device. Figure 5A , Figure 5B , Fig. 6A and Figure 6B The state shown is a reference rotation of 180°. At this time, the +Z direction is called the bottom, the -Z direction is called the top, the rotation axis of the photosensitive member 21 is located below the rotation axis of the developing member 32, and the force receiving surface 621 does not face upward. Specifically, the force receiving surface 621 faces the +Y direction or the +Z direction.

[0063] like Figure 7 As shown, when the developing member 32 and the photosensitive member 21 are in contact with each other, the center line connecting the two is EF, and the movement direction of the movable member 6 after receiving the force applied by the force-applying portion 9 is parallel to the line EF, that is, under the action of the force applied by the force-applying portion 9, the movable member 6 moves along a straight line, and the force-applying portion 9 applies a force to the force-receiving portion 62 along the direction shown by M. The line EF is not parallel to the straight line where the movement direction of the force-applying portion 9 is located. In order to prevent the force-applying portion 9 from slipping when applying force to the force-receiving portion 62, the movable member 6 also includes an anti-slip surface 622 arranged adjacent to the force receiving surface 621, as shown in FIG. Figure 3 , Figure 5A and Fig. 6A As shown, along the +Z direction, the anti-slip surface 622 is located downstream of the force receiving surface 621, and the anti-slip surface 622 at least partially faces the main body 61 / -Z direction. Therefore, the anti-slip surface 622 forms a hook surface relative to the force receiving surface 621, and the force applying part 9 is restricted from falling off from the force receiving surface 621.

[0064] The above describes the movement process of the movable part 6 after being subjected to a force and after the force is removed. Compared with the method described in the background technology that the force-bearing part is fixedly installed in the powder bin, the movable part 6 involved in the present invention is installed in a movable manner. Therefore, even if the processing box 1 is hit or dropped, the movable part 6 will not be easily broken; the advantage of this installation method is that there is no need to change the structure of the processing box 1, and the structure of the existing photosensitive part 21 is directly used to directly install the movable part 6 on the base 213. For the manufacturer of the processing box 1, this method can greatly reduce the manufacturing cost, logistics warehousing cost and assembly cost, and ensure the good connection between the processing box 1 involved in the present invention and the conventional processing box during production.

[0065] Preferably, the movable part 6 can be movably mounted on the base 213 of the photosensitive part 21, and the movement direction of the movable part 6 is parallel to the center line EF of the developing part 32 and the photosensitive part 21 when the two are in contact. Therefore, it is not necessary to provide a larger space for the movement of the movable part 6 in the circumferential direction of the photosensitive part 21, the structure of the processing box 1 is simplified, and the force required to separate the developing part 32 and the photosensitive part 21 from each other is minimized, which is beneficial to reducing the load of the force applying part 9, thereby reducing the power consumption of the electronic photographic imaging device.

[0066] Further, combined with Figure 5A and Figure 7 In the process of the movable part 6 forcing the second unit 3 to rotate, the contact point between the movable part 6 and the rotating shaft moves from point P to point Q. When the moving direction of the movable part 6 is parallel to the connecting line EF, point P and point Q are respectively located on both sides of the connecting line EF. The movable part 6 will not apply a force in the +Z direction of the processing box 1 to the rotating shaft. Therefore, the sealing state between the developing part 32 and the second unit shell 30 is maintained. Similarly, since the movable part 6 will not rotate relative to the photosensitive part 21, the movable part 6 will not affect the sealing state of the first unit shell 20.

[0067] Continue as Figure 7 As shown, the movable member 6 is movably mounted on the base 213 of the photosensitive member 21, so the size of the elliptical coupling hole 611 of the movable member 6 and the size of the photosensitive member 21 satisfy the following relationship:

[0068] The length h2 of the major axis of the coupling hole 611 is greater than the diameter f1 of the photosensitive cylinder 211;

[0069] The length h1 of the minor axis of the coupling hole 611 is greater than the diameter f2 of the base 213 but less than the diameter f1 of the photosensitive cylinder 211;

[0070] By limiting the size of the coupling hole 611 within the above range, it can be effectively ensured that the movable member 6 is mounted on the base 213 in a movable manner without affecting the operation of the photosensitive cylinder 211.

[0071] Specifically in this embodiment, when the movable member 6 is located at the initial position, the developing member 32 is in contact with the photosensitive member 21, and the base 213 of the photosensitive member 21 is closer to the second long axis end 613 of the movable member coupling hole 611; Figure 7 As shown by the middle long dashed line, when the movable member 6 is located at the terminal position, the developing member 32 is separated from the photosensitive member 21, and the base 213 of the photosensitive member 21 is closer to the first long axis end 612 of the movable member coupling hole.

[0072] like Figure 7 As shown, when the movable member 6 is located at the initial position, the forced pushing portion 63 is combined with the rotating shaft 321 at point P, and when the movable member 6 is located at the terminal position, the forced pushing portion 63 is combined with the rotating shaft 321 at point Q. In particular, when the movable member 6 is located at the initial position, when the movable member 6 is forced by the force applying portion 9 to force the rotating shaft 321, the rotating shaft 321 may slip from the bottom of the forced pushing portion 63 (along the +Z direction, at a position upstream of the forced pushing portion 63), causing the first unit 2 (photosensitive member 21) and the second unit 3 (developing member 32) to fail to separate, and when the movable member 6 is provided with an ear portion 64, the ear portion 64 can support the rotating shaft 321 from the bottom of the rotating shaft 321, thereby effectively preventing the rotating shaft 321 from slipping from the forced pushing portion 63.

[0073] Further Figure 7 As shown, since the moving direction of the movable member 6 is parallel to the connecting line EF, when the movable member 6 reaches the terminal position, along the +Z direction, the connecting point Q between the movable member 6 and the rotating shaft 321 is farther away from the ear 64 than the above-mentioned point P.

[0074] Embodiment 2

[0075] Figure 8 : is a three-dimensional diagram of a movable part involved in the second embodiment of the present invention, and the same parts in this embodiment and the above embodiment are numbered the same. As shown in the figure, the movable part 6 in this embodiment is no longer provided with an anti-slip surface 622, and the force receiving surface 621 is set to be a smooth surface, and the movable part 6 also includes a friction member 623 combined with the force receiving surface 621. Preferably, the friction member 623 is a member that can generate a large friction force, such as sandpaper, sponge, etc., and the friction member 623 is combined with the force receiving surface 621 in a pasting manner.

[0076] When the force applying part 9 moves toward the force receiving surface 621 , the force applying part 9 will be combined with the friction member 623 , and the friction force generated between the force applying part 9 and the friction member 623 prevents the force applying part 9 from being out of contact with the movable member 6 .

[0077] Embodiment 3

[0078] Fig. 9: is a three-dimensional diagram of the movable part involved in the third embodiment of the present invention, and the same parts of this embodiment and the above embodiments are numbered the same. As shown in the figure, the difference between the movable part involved in this embodiment and the movable parts involved in the above embodiments one and two is that the joint part 611 of the movable part 6 is no longer elliptical, but circular with a diameter r1, and satisfies that the diameter r1 is between the diameter f1 of the photosensitive cylinder 211 and the diameter f2 of the base 213, specifically: f2<r1<f1. In this embodiment, the movable part 6 no longer moves in a straight line, but moves in a circle around the center of the joint part 611; along the installation direction of the processing box 1, the ear part 64 and the force-bearing part 62 are respectively located on both sides of the forced pushing part 63.

[0079] Similarly, the movable parts involved in this embodiment can still realize the functions of the movable parts in the above embodiments, that is, the movable part 6 is in an active state before being applied with the force by the force applying part 9, the first unit 2 and the second unit 3 are close to each other, and the photosensitive part 21 and the developing part 32 are in contact; the movable part is in an inactive state after being applied with the force by the force applying part 9, the first unit 2 and the second unit 3 are separated from each other, and the photosensitive part 21 and the developing part 32 are out of contact.

[0080] Embodiment 4

[0081] Fig.10 It is a stereoscopic diagram of the movable part involved in the fourth embodiment of the present invention.

[0082] As described above, the movable member 6 is formed in one piece. However, in practice, the main body 61 may also be formed separately from the force-bearing portion 62 and the forced-pushing portion 63. Figure 3 The movable part 6 can be considered to include a mounting portion 6a and an action portion 6b which are separately arranged, wherein the mounting portion 6a corresponds to the above-mentioned main body portion 61, and is used to combine the movable part 6 with other parts of the processing box, and the action portion 6b corresponds to at least one of the above-mentioned force-bearing portion 62 and the pushing portion 63. When the force-applying portion 9 applies a force, the action portion 6b acts on the corresponding part of the processing box, so that the first unit 2 and the second unit 3 are separated from each other, and at the same time, the photosensitive member 21 and the developing member 32 are out of contact.

[0083] Preferably, the acting portion 6b is movable relative to the mounting portion 6a. When the acting portion 6b is subjected to the force applied by the force-applying portion 9, the straight line in which the moving direction of the acting portion 6b lies is parallel to the above-mentioned connecting line EF. Therefore, the overall movement of the movable part 6 is greater, and when the processing box 1 falls or collides, it is more conducive to preventing the movable part 6 from being broken.

[0084] There are two installation methods for the movable member 6 whose action portion 6b is movable relative to the installation portion 6a:

[0085] 1. The mounting portion 6a itself is movably mounted. When the movable member 6 is located at the initial position, both the mounting portion 6a and the action portion 6b are movable. When the movable member 6 is located at the terminal position, the mounting portion 6a is movable and the action portion 6b is immovable; such as the case where the mounting portion 6a is elliptical in the above-mentioned embodiments 1 and 2, and the mounting portion 6a is circular in the embodiment 3, and satisfies the condition: f2<r1<f1.

[0086] 2. The mounting portion 6a itself is fixedly installed. When the movable part 6 is located at the initial position, the mounting portion 6a is immovable, and the action portion 6b is movable. When the movable part 6 is located at the terminal position, both the mounting portion 6a and the action portion 6b are immovable. At this time, no matter whether the mounting portion 6a is elliptical or circular, the component combined with the mounting portion 6a in the processing box is always matched with the mounting portion 6a, so that the mounting portion 6a can be fixedly installed.

[0087] For the second installation method mentioned above, when the acting portion 6b does not receive the force applied by the force-applying portion 9, the acting portion 6b is located in an movable initial position; when the acting portion 6b receives the force applied by the force-applying portion 9, the acting portion 6b moves relative to the mounting portion 6a, and under the further action of the force-applying portion 9, the acting portion 6b forces the first unit 2 and the second unit 3 to separate from each other, and at the same time, the photosensitive member 21 and the developing member 32 are out of contact, at which time the acting portion 6b is located in an immovable terminal position; when the force-applying portion 9 no longer applies a force to the acting portion 6b, the acting portion 6b returns from the immovable terminal position to the movable initial position.

[0088] In this way, the action portion 6b and the mounting portion 6a can be connected by at least one of elastic connection, rack connection, magnetic connection, rail connection, etc. Fig.10 As shown, the mounting portion 6a and the action portion 6b are connected by an elastic member 6c so that the two can move relative to each other. Furthermore, the mounting portion 6a is also provided with a guide groove 6e, and the action portion 6b is also provided with a protrusion 6d, and the protrusion 6d can slide in the guide groove 6e. Therefore, the relative movement trajectory of the mounting portion 6a and the action portion 6b can be precisely controlled.

[0089] Embodiment 5

[0090] According to the above embodiment, this embodiment further describes the installation position of the movable member 6. Based on the technical solution of the present invention, the installation position of the movable member 6 is not limited to the photosensitive member 21, as long as the movable member 6 can receive the force from the force-applying portion 9 and apply the received force to the second unit 3, forcing the second unit 3 to rotate relative to the first unit 2 and separate, and finally separating the developing member 32 from the photosensitive member 21, for example, the movable member 6 can be installed in a movable manner on at least any one of the housing 20 of the first unit 2, the photosensitive member 21, the first end cover 4, the second end cover 5, the housing 30 of the second unit, and the developing member 32.

[0091] For example, when the movable part 6 is movably installed on other components or shells in the processing box 1, specifically, a combined part for combining with the combining part 611 is set in the first unit shell 20, or the combined part is set in the first end cover 4 and the second end cover 5. If this method is adopted, it is necessary to modify the structure of the existing processing box 1. Although it is not conducive to the production connection of the processing box 1 and will increase the above-mentioned various costs, the technical solution involved in this embodiment is still effective for solving the technical problems faced in the background technology.

[0092] Embodiment 6

[0093] Fig.11 Schematic diagram of the inverted processing box involved in the sixth embodiment of the present invention.

[0094] In the above embodiment, if Figure 3 and Figure 8 As shown, the movable part 6 (acting part 6b) has an end surface 624. When the processing box 1 is installed in the imaging device, the end surface 624 is opposite to the force-applying part 9 and presses the force-applying part 9 to the retracted position. However, when the processing box 1 is not working, the force-applying part 9 also needs to apply a force to the force receiving surface 622 to force the developing part 32 to separate from the photosensitive part 21. Therefore, the force-applying part 9 needs to move a distance in the direction opposite to the M direction so as not to be pressed by the end surface 624. Obviously, when the developing part 32 and the photosensitive part 21 need to be separated, the force-applying part 9 first needs to move a long distance in the M direction before it can apply a force to the force receiving surface 622. Generally speaking, the movement process of the force-applying part 9 is relatively complicated, and the structure of the imaging device is not simplified enough.

[0095] To this end, the movable part 6 involved in this embodiment is still installed in an at least partially movable manner, and its structure is further optimized. While effectively preventing the movable part 6 from being broken due to collision or falling of the processing box 1, it can also simplify the movement process of the force-applying part 9, thereby simplifying the structure of the imaging device.

[0096] When the processing box 1 is installed to the imaging device, the rotation axis of the photosensitive member 21 is located below relative to the rotation axis of the developing member 32, and the force receiving surface 6b1 of the movable member 6 used to combine with the force applying portion 9 does not face upward. Preferably, the force receiving surface 6b1 faces the +Z and +Y directions, so that the force applying portion 9 can smoothly contact the force receiving surface 6b1.

[0097] Along the Z direction, the free end 6h of the movable member 6 is not opposite to the force-applying portion 9, but the force-receiving surface 6b1 is opposite to the force-applying portion 9. Therefore, during the installation and removal of the processing box 1 along the Z direction, the force-applying portion 9 does not need to be extended or retracted, nor does it need to be moved in the direction opposite to the direction indicated by M to avoid interference with the processing box 1. It only needs to be moved in the direction indicated by M to apply a force to the movable member 6 and move in the direction opposite to the direction indicated by M to break contact with the movable member 6, thereby simplifying the structure of the imaging device. More preferably, when the processing box 1 moves in the +Z direction, the free end 6h is located in the -Y direction of the force-applying portion 9, not only does the movable member 6 not interfere with the force-applying portion 9, but also when the processing box 1 is not working, the force-applying portion 9 can be combined with the movable member 6 by moving in the direction indicated by M, and when the processing box 1 is working, the force-applying portion 9 can be moved in the direction opposite to the direction indicated by M to the position before the processing box 1 moves in the +Z direction. It can be seen that the movement distance of the force-applying portion 9 in this embodiment is smaller than that of the existing force-applying portion 9.

[0098] Fig.12 is a schematic diagram of some exploded components of a powder bin in a process box according to a sixth embodiment of the present invention; Fig.13 It is a stereoscopic diagram of movable parts in the processing box involved in the sixth embodiment of the present invention.

[0099] The powder bin 3 also includes a bracket 31, a power receiving member 33, a developing member gear 324 and a supply member gear 341 installed on the same side as the second end cover 5, wherein the power receiving member 33 is meshed with the developing member gear 324 and the supply member gear 341 at the same time, and the power receiving member transmits the driving force received from the outside to the developing member 32 and the supply member 34 through the developing member gear 324 and the supply member gear 341 to drive the developing member 32 and the supply member 34 to rotate; the power receiving member 33, the developing member 32 and the supply member 34 are all supported by the bracket 31, and the developing member gear 324 and the supply member gear 341 are fixedly installed at the longitudinal ends of the developing member 32 and the supply member 34, respectively.

[0100] Correspondingly, a transmission part for combining with the movable part 6 is provided in the powder bin 3. When the movable part 6 receives the force applied by the force applying part 9, the movable part 6 transmits the force to the powder bin 3 through the transmission part, thereby forcing the powder bin 3 to separate from the waste powder bin 2. Specifically, the transmission part can be a transmission surface 311 provided on the bracket 31, or a transmission surface provided on the powder bin housing 30.

[0101] Optionally, the powder bin 3 further includes a protective cover 35 arranged in the +X direction of the bracket, and the protective cover 35 is used to prevent the power receiving member 33, the developing member gear 324 and the supply member gear 341 from falling off. The transmission part can also be a transmission surface 351 arranged on the protective cover 35. Preferably, the transmission surface 311 / 351 is set as an inclined surface, such as Fig.14A As shown, the transfer surface 311 / 351 is inclined toward the −Y and +Z directions, or in other words, along the −Y direction, the transfer surface 311 / 351 gradually moves away from the developing member 32 .

[0102] The setting of the transfer surface 311 / 351 can make the combination of the movable part 6 and the powder bin 3 smoother, and the wear of the movable part 6 can be reduced. Therefore, the setting of the transfer surface 311 / 351 is not necessary; when the transfer surface 311 / 351 is not set, the movable part 6 is directly combined with the corresponding position of the powder bin 3, and can also transmit the force to the powder bin 3, thereby achieving the purpose of forcing the developing part 32 and the photosensitive part 21 to separate from each other.

[0103] As described above, the movable part 6 includes a mounting portion 6a and an action portion 6b which are connected to each other, and the mounting portion 6a is used to install the movable part 6. For example, the movable part 6 is installed in the waste powder bin 2 through the mounting portion 6a, or is installed on the first end cover 4, or is installed on the second end cover 5. In the following, the movable part 6 is installed in the waste powder bin 2 through the mounting portion 6a as an example.

[0104] Further, the movable member 6 is mounted on the photosensitive member 21 through the mounting portion 6a, and the action portion 6b is formed by protruding from the mounting portion 6a. Preferably, the mounting portion 6a is formed with a circle 611 for combining with the photosensitive member 21, and the action portion 6b is a flat plate protruding from the mounting portion 6a. After the mounting portion 6a is installed, the action portion 6b can rotate with the mounting portion 6a. Fig.11 As shown, when the movable part 6 is installed to the photosensitive part 21, the two are arranged concentrically, and one surface of the action part 6b is formed as a force receiving surface 6b1 for combining with the force applying part 9. The force receiving surface 6b1 can be a smooth surface, or a friction part attached to the smooth surface to increase the friction force when combined with the force applying part 9. When the action part 6b receives the force applied by the force applying part 9, the mounting part 6a rotates around the rotation axis of the photosensitive part 21, and the action part 6b transmits the force to the transmission part.

[0105] Furthermore, the movable part 6 is also provided with a limiting part 6f for limiting the rotation of the movable part 6 to prevent the action part 6b (force receiving surface 6b1) from failing to reach the predetermined position under extreme circumstances; preferably, the limiting part 6f is a protrusion protruding radially outward from the mounting part 6a, and optionally, the limiting part 6f can also be a protrusion protruding outward from the mounting part 6f along its rotation axis.

[0106] Fig.14A and Fig. 14B It is a schematic diagram of the state before and after the processing box involved in the present invention is combined with the force applying part.

[0107] In order to make the state change of the processing box 1 more clearly displayed, Fig.14A and Fig. 14B The waste toner bin 2 in the processing box 1 only retains the photosensitive member 21 and the movable member 6. Fig.14A As shown, the surface of the developing member 32 is in contact with the surface of the photosensitive member 21. At this time, the force applying portion 9 is not in contact with the action portion 6b of the movable member 6, and the action portion 6b is in contact with or not in contact with the transmission portion.

[0108] When the processing box 1 is not working, Fig. 14B As shown, the force-applying portion 9 gradually approaches the force receiving surface 6b1 along the direction indicated by M. When the force-applying portion 9 begins to press the force receiving surface 6b1 and apply the force, the action portion 6b drives the mounting portion 6a to rotate around the rotation axis of the photosensitive member 21. A surface of the action portion 6b opposite to the force receiving surface 6b1 contacts the transmission surface 311 / 351, and the force is transmitted to the powder bin 3. Finally, the powder bin 3 rotates around the axis L along the direction indicated by r and separates from the waste powder bin 2. At the same time, the developing member 32 and the photosensitive member 21 are also separated from each other.

[0109] When the processing box 1 needs to start working again, the force-applying part 9 moves in the direction opposite to the direction indicated by M to release the pressure on the force receiving surface 6b1. Under the action of the elastic member 7 located between the powder bin 3 and the waste powder bin 2, the powder bin 3 rotates in the direction opposite to the direction indicated by r and returns to a position close to the waste powder bin 2. At this time, the developing member 32 also returns to a position in contact with the photosensitive member 21.

[0110] When the movable part 6 is installed on the second end cover 5, for example, a matching portion for matching with the mounting portion 6a is provided on the second end cover 5, and when the mounting portion 6a is provided with a circle 611, the matching portion is a cylinder protruding from the second end cover 5, and the mounting portion 6a is sleeved on the cylinder.

[0111] Embodiment 7

[0112] The same components as those in the sixth embodiment are numbered the same. The difference between the two is the structure of the movable member 6. Fig.11 As shown, the acting portion 6b includes a first protrusion 6g1 protruding from the mounting portion 6a and a second protrusion 6g2 protruding from the first protrusion, wherein the first protrusion 6g1 has a first force receiving surface 6b1, and the second protrusion 6g2 has a second force receiving surface 6b2.

[0113] When the process cartridge 1 is Fig.11When placed inverted as shown, neither the first force receiving surface 6b1 nor the second force receiving surface 6b2 faces upward. Specifically, the first force receiving surface 6b1 faces downward, and the second force receiving surface 6b2 faces in the +Y direction, that is, the second force receiving surface 6b2 is parallel to the up and down direction (vertical direction) of the processing box 1; similarly, along the Z direction, the free end 6h of the movable part 6 (the free end of the second protrusion 6g2) is opposite to the force applying part 9, and when the processing box 1 moves along the +Z direction, the free end 6h is located in the -Y direction of the force applying part 9. Therefore, the force applying part 9 does not need to be extended or retracted, nor does it need to move in the direction opposite to the direction indicated by M to avoid interfering with the processing box 1. It only needs to move in the direction indicated by M to apply a force to the movable part 6 and move in the direction opposite to the direction indicated by M to break contact with the movable part 6. The structure of the imaging device is simplified, and relative to the movement distance of the existing force applying part 9, the movement distance of the force applying part 9 in this embodiment is smaller.

[0114] Embodiment 8

[0115] The same components as those of the sixth and seventh embodiments are numbered the same. Since the movable member 6 can rotate around its rotation axis, when the force applying portion 9 moves toward the movable member 6 (acting portion 6b), the movable member 6 (acting portion 6b) is located at a predetermined force receiving position. Preferably, the movable member 6 is always combined with the powder bin 3. Fig.11 As shown, the process cartridge 1 further includes a retaining member 36 for retaining the action portion 6b (force receiving surface 6b1) at a predetermined force receiving position.

[0116] As shown in the figure, the retaining member 36 is located between the movable member 6 and the powder bin 3 (powder bin housing 30) or between the movable member 6 and the waste powder bin 2 (waste powder bin housing 20). Preferably, the retaining member 36 is an elastic member, such as a compression spring, a tension spring, an elastic rubber, etc. The predetermined force receiving position is the position where the action portion 6b contacts the transmission portion. Once the force applying portion 9 begins to contact the action portion 6b, the action force can be transmitted to the powder bin 3; at the same time, when the processing box 1 moves along the +Z direction, the action portion 6b is maintained at the predetermined force receiving position, which can also effectively prevent interference between the movable member 6 and the force applying portion 9.

[0117] Furthermore, the limiting member 6f is used to limit the rotation of the movable member 6, and thus, the limiting member 6f can also be considered as another embodiment of the retaining member 36, such as Fig.11 As shown, the restricting member 6f is arranged so that, when the process cartridge 1 is mounted, the movable member 6 is held with the acting portion 6b located at a predetermined force receiving position.

[0118] Embodiment 9

[0119] The same components as those in the above embodiments are numbered the same. The above describes an embodiment in which the first end cover 4 and the second end cover 5 are independent components, and the powder bin 3 and the waste powder bin 2 are combined together through the first end cover 4 and the second end cover 5.

[0120] This embodiment will describe the deformation mode of the first end cover 4 and the second end cover 5, that is, the first end cover 4 is decomposed into two sub-end covers respectively combined with the powder bin 3 and the waste powder bin 2, and the second end cover 5 is also divided into two sub-end covers respectively combined with the powder bin 3 and the waste powder bin 2. At this time, the sub-end covers of the first end cover 4 respectively combined with the powder bin 3 and the waste powder bin 2 will become a part of the powder bin 3 and a part of the waste powder bin 2, respectively, and correspondingly, the sub-end covers of the second end cover 5 respectively combined with the powder bin 3 and the waste powder bin 2 will become a part of the powder bin 3 and a part of the waste powder bin 2, respectively.

[0121] In this embodiment, the powder bin 3 and the waste powder bin 2 are still connected by the first end cover 4 and the second end cover 5. Specifically, the powder bin 3 and the waste powder bin 2 are connected by two sub-end covers of the first end cover 4 and two sub-end covers of the second end cover 5. The connection method is preferably pin connection, so that the powder bin 3 and the waste powder bin 2 can rotate relative to each other. Optionally, the sub-end cover of the second end cover 5 connected to the powder bin can be equivalent to the protective cover 35, and either one can be selected.

[0122] In this embodiment, the movable part 6 can be installed on one of the waste toner bin housing 20, the sub-end cover of the first end cover 4 combined with the waste toner bin, the sub-end cover of the second end cover 5 combined with the waste toner bin, and the photosensitive member.

[0123] like Fig.11 As shown, the processing box 1 also includes a charging member 22 rotatably mounted in the waste toner bin housing 20, the charging member 22 is in contact with the photosensitive member 21, and is used to charge the surface of the photosensitive member 21, and optionally, the mounting portion 6a of the movable member 6 can also be mounted on the charging member 22. Further, since the photosensitive member 21 and the charging member 22 are both rotatably mounted in the waste toner bin housing 20, the photosensitive member 21 and the charging member 22 can be collectively referred to as a rotating member, and the mounting portion 6a of the movable member 6 is mounted on the rotating member in the waste toner bin 2.

[0124] Embodiment 10

[0125] Fig.15 is a three-dimensional diagram of a movable part involved in Embodiment 10 of the present invention; Fig.16 is a schematic diagram of a state after the process cartridge involved in the tenth embodiment of the present invention is installed in an image forming device; Fig.17 It is a schematic diagram of the state of the movable part involved in the tenth embodiment of the present invention when it is combined with the force applying part.

[0126] This embodiment mainly describes the structural improvement of the movable member 6, and the same components as those in the above embodiment will be numbered the same.

[0127] For the processing box 1 equipped with the movable member 6 involved in the sixth embodiment, in practice, the inventors found that the force-applying portion 9 may pass over the free end 6h and cause the force-receiving surface 6b1 to be separated from the force-receiving surface 6b1 during the process of applying the force to the force-applying portion 9. Therefore, it is a common method to extend the action portion 6b longer. However, after the action portion 6b is extended, when the processing box 1 is installed in the imaging device, the free end 6b of the movable member may interfere with the guide rail 10 in the imaging device, such as Fig. 14B Shown by the dashed line.

[0128] In this embodiment, the acting portion 6 b of the movable member 6 is configured to be variable in length to overcome the defect that the extended acting portion 6 b interferes with the guide rail 10 .

[0129] like Fig.15 As shown, the movable part 6 in this embodiment includes a mounting portion 6a and an action portion 6b that are interconnected. The mounting portion 6a is used to mount the movable part 6 to a corresponding component, and the action portion 6b extends outward from the mounting portion 6a and is used to combine with a force-applying portion 9 in the imaging device and receive the force applied by the force-applying portion 9 to force the developing member 32 and the photosensitive member 21 to separate from each other, or to force the first unit 2 and the second unit 3 to separate from each other.

[0130] The acting portion 6b includes a first portion 6m connected to the mounting portion 6a and a second portion 6n connected to the first portion 6m, wherein at least one of the first portion 6m and the second portion 6n is deformable, thereby making the length s of the acting portion 6b variable; the length s of the acting portion 6b herein refers to the length measured along the extension direction of the acting portion 6b, starting from the connection between the acting portion 6b and the mounting portion 6a to the free end 6h of the movable part.

[0131] The first part 6m and the second part 6n are formed integrally, the first part 6m forms a force receiving surface 6b1, and the second part 6n is deformable. Specifically, the second part 6n includes a bending portion 6p, a blocking surface 6n1 and a pressing surface 6n2 arranged therein. Fig.16 As shown by the middle dotted line, when the processing box 1 is installed, the force receiving surface 6b1, the blocking surface 6n1 and the pressing surface 6n2 are not facing upward, the free end 6h of the movable part is in contact with the guide rail 10, and under the gravity squeezing of the processing box 1, the bending part 6p is elastically deformed, the interference between the movable part 6 and the guide rail 10 disappears, and the processing box 1 can be smoothly installed. At this time, the movable part 6 is located in the immovable initial position.

[0132] like Fig.17As shown in the figure, only the photosensitive member 21, the movable member 6 and the force-applying part 9 are shown. When the force-applying part 9 starts to combine with the action part 6b, once the force-applying part 9 passes over the force receiving surface 6b1, the force-applying part 9 will start to contact the second part 6n until the force-applying part 9 abuts against the blocking surface 6n1, that is, the movable member 6 starts to move from the initial position to the terminal position. Specifically, the movable member 6 rotates around the rotation axis. In this process, the force-applying part 9 squeezes the bent portion 6p. Since the first portion 6m has abutted against the transmission surface 351 / 311, the second portion 6n will move along the bent portion 6p. Fig.17 When the blocking surface 6n1 contacts the force-applying portion 9, the second portion 6n stops rotating and the force-applying portion 9 also stops moving. At this time, the movable member 6 reaches the terminal position, and the force applied by the force-applying portion 9 can also be transmitted to the second unit 3 through the pressing surface 6n2. Finally, the second unit 3 moves along Fig.14A The first unit 2 and the second unit 3 are rotated in the direction indicated by r, and the first unit 2 and the second unit 3 are separated from each other, and at the same time, the photosensitive member 21 and the developing member 32 are separated from each other. When the force applying part 9 moves in the direction opposite to the direction indicated by M, the force applied by the force applying part 9 disappears, and under the elastic restoring force of the elastic member 7, the second unit 3 forces the movable member 6 to reset through the transmission surface 351 / 311, that is, the movable member 6 returns from the terminal position to the initial position, and the first unit 2 and the second unit 3 return to the position close to each other again, and the photosensitive member 21 and the developing member 32 are also in contact again.

[0133] On the premise that the length s of the action portion 6b is variable and the action portion 6b is formed in one piece, this embodiment can also be implemented in a variety of ways. For example, the positions of the first part 6m and the second part 6n are interchanged. Furthermore, the bending portion 6p is connected to the mounting portion 6a, or the bending portion 6p is replaced by an elastic material, etc., all of which can achieve the purpose of the present invention. They are not listed one by one here.

[0134] Embodiment 11

[0135] Fig.18 It is a three-dimensional diagram of the movable part involved in the eleventh embodiment of the present invention.

[0136] This embodiment makes a change to the action portion 6b in the tenth embodiment, wherein the action portion 6b is formed in a split body and still includes a first portion 6m and a second portion 6n, but along the extension direction of the action portion 6b, the first portion 6m and the second portion 6n can be relatively retractable, such as Fig.18 As shown, the first portion 6m is fixedly connected to the mounting portion 6a, and the second portion 6n is retractable relative to the first portion 6m, so that its length s is variable along the extending direction of the action portion 6b.

[0137] Similarly, after the processing box 1 equipped with the movable part 6 involved in this embodiment is installed in the imaging device, the free end 6h of the movable part interferes with the guide rail 10. Under the action of the gravity of the processing box 1 itself, the second part 6n retracts into the first part 6m, so that the processing box 1 can be installed smoothly. At this time, the force receiving surface 6b1 formed on the first part 6m and the blocking surface 6n1 formed on the second part 6n are not facing upward.

[0138] When the force-applying portion 9 begins to contact the action portion 6b, the mounting portion 6a begins to rotate around the center of its coupling portion 611, and the surface of the first portion 6m opposite to the force receiving surface 6b1 begins to push the transmission surface 351 / 311, thereby causing the second unit 3 to rotate relative to the first unit 2 and separate from each other. At the same time, the photosensitive member 21 and the developing member 32 are also separated from each other.

[0139] When the force-applying portion 9 is no longer in contact with the action portion 6b, under the elastic restoring force of the elastic member 7, the second unit 3 forces the movable member 6 to rotate in the opposite direction and reset. At the same time, the first unit 2 and the second unit 3 approach each other again, and the photosensitive member 21 and the developing member 32 also contact again.

[0140] Embodiment 12

[0141] Fig.19 is a three-dimensional diagram of a movable member involved in Embodiment 12 of the present invention; Fig. 20 is a schematic diagram of the exploded view of the movable parts involved in the twelfth embodiment of the present invention; Fig.21 It is a schematic diagram of the state of the processing box involved in the twelfth embodiment of the present invention before being combined with the force applying portion.

[0142] According to actual test results, the movable parts involved in this embodiment are further improved, such as Fig.19 As shown, the movable part 6 includes a mounting portion 6a and an action portion 6b that are connected to each other, the mounting portion is installed through a coupling portion 611, and the action portion 6b is used to combine with the force-applying portion 9 and receive the force applied by the force-applying portion 9 to force the first unit 2 and the second unit 3 to separate from each other; the action portion 6b is movable relative to the mounting portion 6a, specifically, the action portion 6b is retractable relative to the mounting portion 6a, and thus, along the extension direction of the action portion 6b, its length is variable.

[0143] like Fig. 20 As shown, the mounting portion 6a is provided with a mounting hole 6a1, and the action portion 6b includes an action block 6b5 and a guide block 6b6 which are connected to each other, the guide block 6b6 is accommodated by the mounting hole 6a1 and can move in the mountable hole 6a1, and the action block 6b5 forms a force receiving surface 6b1 and a force output surface 6b3, wherein the force receiving surface 6b1 is used to receive the force applied by the force applying portion 9, and the force output surface 6b3 transmits the force to the transmission surface 351 / 311 on the powder bin.

[0144] In order to prevent the guide block 6b6 from sliding out of the mounting hole 6a1, the movable member 6 is connected by a pin to achieve this purpose. Fig. 20 The mounting portion 6a is provided with a pin hole 6a2, and the guide block 6b6 is provided with a long hole 6a7. A pin (not shown) passes through the pin hole 6a2 and the long hole 6a7 at the same time, thereby preventing the action portion 6b from being disengaged from the mounting portion 6a.

[0145] like Fig.21 As shown, in order to more clearly show the structure related to the present invention in the processing box 1, the first unit housing 20 and the second end cover 5 are hidden. After the processing box 1 is installed in the imaging device, the force receiving surface 6b1, the force output surface 6b3 and the transmission surface 311 do not face upward. Preferably, the force receiving surface 6b1 and the transmission surface 311 face the +Y direction, or the direction opposite to the movement direction M of the force applying part 9, and the force output surface 6b3 faces the -Y direction, or the direction in the same direction as the movement direction M of the force applying part 9. Therefore, when the force applying part 9 moves to the force receiving surface 6b1, the two can be combined more smoothly.

[0146] When the force-applying portion 9 applies a force to the force-receiving surface 6b1, the action portion 6b begins to move in the direction indicated by M. Since the action portion 6b can be variable in length under the action of the guide block 6b6 and the mounting hole 6a1, the action portion 6b can move along with the movement of the force-applying portion 9. During this process, the mounting portion 6a can remain stable without being affected by the movement of the action portion 6b. Furthermore, even if the stroke of the force-applying portion 9 is too long and the action portion 6b is restricted by the pin and cannot continue to move in the direction indicated by M, the action portion 6b can rotate around the axis along with the mounting portion 6a, and the adverse result of the action portion 6b being separated from the mounting portion 6a will not occur.

[0147] Furthermore, in the process that the movable member 6 is subjected to the force application part 9, in order to prevent the movable member 6 from swinging and causing unstable operation, as Fig.19 and Fig. 20 As shown, the movable part 6 also includes a limiting column 6i arranged on the mounting portion 6a, and the limiting column 6i is used to abut against components other than the movable part 6 in the processing box 1, for example, the limiting column 6i abuts against the second end cover 5; further, the force output surface 6b3 and the transmission surface 311 are arranged to be arc surfaces that cooperate with each other, so that even if the action portion 6b is deflected, the movable part 6 can eventually stably transmit the action force to the second unit 3.

[0148] As described above, at least a portion of the movable member 6 is installed in a movable manner. Even if the processing box 1 falls or collides, the movable member 6 has a certain amount of movement, so the chance of the movable member 6 being broken can be greatly reduced.
