[0050] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0051] [Overall structure of the process cartridge]

[0052] Figure 1 It is a schematic diagram of a state in which a developing box and a drum frame in a processing box involved in the utility model are separated from each other.

[0053] The processing box C includes a developing box 100 and a drum frame 200 that are detachably combined with each other. The developing box 100 contains the developer required for development. Before use, the user needs to install the developing box 100 to the drum frame 200, and then install the combination of the developing box 100 and the drum frame 200 to the imaging device in a detachable manner. When the developer is consumed, the user takes the combination of the developing box 100 and the drum frame 200 out of the imaging device, and replaces it with a new developing box 100 for continued use.

[0054] The developing box 100 includes a developing shell 1 for accommodating a developer, a developing roller 12 rotatably arranged in the developing shell 1, an end cover 11 connected to the developing shell 1, and a driving force receiving member 13 exposed through the end cover 11, wherein the driving force receiving member 13 is used to receive a driving force from an imaging device to drive the developing roller 12 to rotate around a rotation axis L1.

[0055] In the following, for the convenience of description and understanding, the extension direction of the rotation axis L1 is defined as the first direction / longitudinal direction / left-right direction, and the state when the developing box 100 / processing box C is normally placed on the desktop is taken as the standard. The height direction of the developing box 100 / processing box C is the second direction / vertical direction / up-down direction, and the second direction intersects with the first direction. The direction intersecting with both the first direction and the second direction is the third direction / lateral direction / front-back direction. Preferably, the first direction, the second direction and the third direction are orthogonal. Furthermore, the side where the driving force receiving member 13 is located is called the driving side C1 (left), and along the first direction, the side opposite to the driving side C1 is the non-driving side C2 (right), and therefore, the end cover 11 is installed on the driving side C1.

[0056] The drum frame 200 has the same orientation as the developing box 100, and the drum frame 200 includes a drum shell 21, a photosensitive drum 22 rotatably arranged in the drum shell 21, and a developing box accommodating chamber 23 enclosed by the drum shell 21. When the developing box 100 is installed in the developing box accommodating chamber 23, the developing roller 12 and the photosensitive drum 22 are close to each other and are in a relative arrangement state, so that the developing roller 12 can supply the developer to the photosensitive drum 22.

[0057] Furthermore, the developing box 100 also includes a left positioning portion 16L and a right positioning portion 16R respectively located at the two longitudinal ends of the developing shell, and the drum frame 200 also includes a left positioning groove 24L and a right positioning groove 24R arranged at the two longitudinal ends of the drum shell. In the process of the developing box 100 and the drum frame 200 being combined with each other, the left positioning portion 16L and the right positioning portion 16R respectively enter the left positioning groove 24L and the right positioning groove 24R, and then the developing box 100 rotates around the left positioning portion 16L and the right positioning portion 16R until the developing box 100 reaches a predetermined installation position in the developing box accommodating cavity 23.

[0058] As described in the background art, in order to enable the imaging device to obtain information of the developing box 100 and the drum frame 200, at least one of the developing box 100 and the drum frame 200 is also provided with a chip mechanism 3 (such as Figure 3A As shown), when the processing box C is installed in the imaging device, the chip mechanism 3 is electrically contacted with the contact pin in the imaging device; preferably, the developing box 100 and the drum frame 200 are both provided with chips, which will be described separately below.

[0059] [Example 1]

[0060] Figure 2A It is a three-dimensional diagram of the developing box and the drum frame in the processing box involved in the first embodiment of the utility model before they are combined with each other; Figure 2B Observe along the first direction Figure 2A A side view of the middle processing box; Figure 3A It is a three-dimensional diagram of the development box and the drum frame in the processing box involved in the first embodiment of the utility model after being combined with each other; Figure 3B Observe along the first direction Figure 3A Side view of the processing box in the figure.

[0061] In this embodiment, the chip mechanism 3 is entirely arranged on the driving side C1, and the chip mechanism 3 includes a first chip assembly 14, a second chip assembly 25 and a connecting assembly, wherein the first chip assembly 14 is arranged in the developing box 100, and at least a part of the second chip assembly 25 is movably arranged in the drum frame 200, and along the third direction, at least a part of the connecting assembly is located between the first chip assembly 14 and the second chip assembly 25. As the developer box 100 is installed in the developer box accommodating chamber 23, at least a portion of the second chip assembly 25 moves relative to the drum shell 21, that is, the position of at least a portion of the second chip assembly 25 relative to the drum shell 21 changes. For example, at least a portion of the second chip assembly 25 can move relative to the drum shell 21 in the second direction, or at least a portion of the second chip assembly 25 moves relative to the drum shell 21 in the third direction, or at least a portion of the second chip assembly 25 moves relative to the drum shell 21 in the first direction. That is to say, at least a portion of the second chip assembly 25 moves in a direction intersecting at least any one of the first direction, the second direction and the third direction, and the movement causes at least a portion of the second chip assembly 25 to move from a position where it cannot electrically communicate with the corresponding contact pin (second contact pin) in the imaging device to a position where at least a portion of the second chip assembly 25 can electrically communicate with the corresponding contact pin in the imaging device. The position of the contact pin (second contact pin) being electrically connected, or in other words, the movement enables at least a portion of the second chip component 25 to move from a non-operable position to a workable position, that is, at least a portion of the second chip component 25 can move between a first position and a second position, the first position is a position where at least a portion of the second chip component 25 cannot be electrically connected to the corresponding contact pin (second contact pin) in the imaging device, and the second position is a position where at least a portion of the second chip component 25 can be electrically connected to the corresponding contact pin (second contact pin) in the imaging device. Generally, in the state of electrical connection, at least a portion of the second chip component 25 is in contact with the corresponding contact pin (second contact pin), or the first position is that at least a portion of the second chip component 25 is located in a non-operable position, and the second position is that at least a portion of the second chip component 25 is located in a workable position; it is achievable that the movement mode can be either rotation or movement.

[0062] The first chip assembly 14 includes a first chip 143 and a first support portion 142 for supporting the first chip 143. Generally, as shown in FIG. Fig.10As shown, the first chip 143 includes a substrate 143a, an electrical contact portion 143b arranged on the substrate 143a, and a storage portion (not shown) electrically connected to the electrical contact portion 143b, wherein the storage portion is used to store various preset parameter information, and the electrical contact portion 143b is used to electrically connect to a corresponding contact pin (first contact pin) in the imaging device, so that the first chip 143 and the imaging device can establish a communication connection. It can be seen that the storage portion and the electrical contact portion 143b do not have to be arranged on the substrate at the same time, and the two can be arranged separately and electrically connected through a wire. Therefore, the first support portion 142 can also be configured to only support the electrical contact portion 143b.

[0063] Among them, the first support part 142 can be set on the end cover 11 or on the developing housing 1. Preferably, the first support part 142 is formed integrally with the end cover 11 / developing housing 1, so that the installation step of the first support part 142 can be omitted, and the position of the first support part 142 in the developing box 100 can be accurately located. Finally, the first chip 143 can form a stable electrical connection with the corresponding contact pin (first contact pin).

[0064] In some embodiments, Figure 2A As shown, to ensure that the electrical contact portion 143b can stably contact the corresponding contact pin (first contact pin), a first elastic member 141 is further provided between the first support portion 142 and the electrical contact portion 143b. The first elastic member 141 is used to force the electrical contact portion 143b to move toward the contact pin.

[0065] The second chip assembly 25 includes a second chip 43 and a second supporting portion 42 for supporting the second chip 43. Under the action of the connecting component, the second supporting portion 42 can force at least a portion of the second chip assembly 25 to move in a predetermined direction, so that at least a portion of the second chip assembly 25 moves from the first position to the second position; wherein the second chip 43 has the same structure as the first chip 143, which will not be repeated here, and the second supporting portion 42 can also be configured to only support the electrical contact portion of the second chip 43. At this time, the movement of the above-mentioned second chip assembly 25 will become the movement of only the electrical contact portion of the second chip 43.

[0066] Furthermore, the chip mechanism 3 further includes a stopper 46 for preventing the second chip assembly 25 from falling off. When the second chip assembly 25 is configured to move along the second direction, as shown in FIG. Figure 3A and Figure 3BAs shown, the limit member 46 is provided with a guide groove having an upper end 461b and a lower end 461a, and a guide protrusion 421 is provided on the second support portion 42, and the guide groove extends along the second direction. Through the cooperation between the guide protrusion 421 and the guide groove, the second chip component 25 is moved along the second direction; in some embodiments, the positions of the guide protrusion 421 and the guide groove can also be interchanged.

[0067] In some embodiments, when the second chip assembly 25 is configured to move along a first direction, the guide groove may be configured to extend along the first direction, and when the second chip assembly 25 is configured to move along a third direction, the guide groove may be configured to extend along the third direction.

[0068] In other embodiments, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip may also be configured to rotate around an axis, thereby enabling the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip to move from a non-operable position to an operable position.

[0069] It is understandable that, regardless of whether the electrical contact portion of the second chip component 25 / the second chip 43 / the second chip moves between the first position and the second position by rotation or by movement, the force used to force the electrical contact portion of the second chip component 25 / the second chip 43 / the second chip to move always comes from the connecting component.

[0070] The connecting component includes a force-applying member 311 arranged in the developing box 100, a connecting member 44 combined with the second chip component 25, and a transmission member 41 located between the force-applying member 311 and the connecting member 44. In the present embodiment, the force-applying member 311 is a force-applying protrusion arranged on the end cover 11 or the developing housing 1. Preferably, the force-applying protrusion is formed integrally with the end cover 11 or the developing housing 1. By setting the position of the force-applying protrusion, the magnitude and direction of the force applied by the force-applying protrusion to the transmission member 41 can be determined, and then the movement range / movement distance of the second chip component 25 is determined by the transmission member 41 and the connecting member 44.

[0071] In this embodiment, the connecting member 44 is configured as an elastic member, for example, the connecting member 44 is a compression spring, rubber, sponge, tension spring, etc., one end of the connecting member 44 is combined with the second chip assembly 25, and the other end is combined with the transmission member 41. Preferably, the connecting member 44 is a compression spring, one end of the compression spring 44 abuts against the second support portion 42, and the other end abuts against the transmission member 41. When the developing cartridge 100 is taken out of the drum frame 200, the connecting member 44 configured as a compression spring can be used to force the transmission member 41 to reset.

[0072] The transmission member 41 is configured as a rod that can rotate around a rotation axis L2. Preferably, the rotation axis L2 is parallel to the first direction. Figure 2A and Figure 3A As shown, the transmission member 41 includes a rotating portion 41 c and a force-bearing portion 41 a and a pushing portion 41 b respectively located at two ends of the rotating portion 41 c . The force-bearing portion 41 a is used to abut against the force-applying member 311 and receive the force applied by the force-applying member 311 .

[0073] like Figure 2B As shown, before the developing box 100 is installed, the pushing portion 41b is under the action of its own gravity or the initial elastic force applied by the compression spring 44, and the transmission member 41 is tilted relative to the third direction as a whole. At this time, along the second direction, the pushing portion 41b is located below the force-bearing portion 41a, and the guide protrusion 421 is close to the lower end 461a of the guide groove. The second chip 43 is in a retracted state that does not exceed the limit member 46 along with the second supporting portion 42, that is, the second chip 43 / second chip assembly 25 is in a non-operating position. In this way, in the developing box During the combination process of the developing box 100 and the drum frame 200, and during the installation of the combination of the developing box 100 and the drum frame 200 toward or removal from the imaging device, the second chip 43 will not be scratched and will be protected; preferably, the chip mechanism 3 also includes a support member 45 for supporting the pushing portion 41b, and the support member 45 can limit the initial position of the pushing portion 41b to prevent the transmission member 41 from tilting at too large an angle, resulting in the pushing portion 41b being unable to transmit the force to the second chip assembly 25, or the transmitted force is too small.

[0074] As the developing cartridge 100 is installed, the force applying member 311 begins to abut against the force receiving portion 41a, and then the transmission member 41 rotates around the rotation axis L2, the guide protrusion 421 moves along the guide groove toward the upper end 461b, and the forced pushing portion 41b forces the compression spring 44 to cause the second chip 43 / the electrical contact portion of the second chip to protrude upward in the second direction to exceed the limit member 46, as shown in FIG. Figure 3B As shown, the second chip 43 / second chip assembly 25 / electrical contact portion of the second chip is in an operable position, at which time the second chip 43 / electrical contact portion of the second chip can be electrically connected to the corresponding contact pin (second contact pin) in the imaging device.

[0075] It can be seen that after the developing box 100 and the drum frame 200 are combined with each other, the second chip 43 / the electrical contact part of the second chip reaches the working position / the second position, and in the process of installing the combination of the developing box 100 and the drum frame 200 toward the imaging device, even if the contact pin in the imaging device is in contact with the first chip 143 and the second chip 43, under the action of the first elastic member 141 and the connecting member 44, the first chip 143 and the second chip 43 can move downward along the second direction, so that the combination of the developing box 100 and the drum frame 200 can be installed smoothly, and the scratches / wear on the first chip 143 and the second chip 43 are reduced.

[0076] According to the above description, during the installation and removal of the developing cartridge 100, the first chip assembly 14 does not need to interact with the connecting assembly, and thus, the first chip assembly 14 and the connecting assembly can be separated from each other. Figure 2B and Figure 3B As shown, along the second direction, the first chip assembly 14 and the force-applying member 311 are spaced apart, that is, the first chip assembly 14 does not need to cooperate with the connecting assembly / force-applying member 311, which reduces the manufacturing accuracy requirements of the chip mechanism 3; in some embodiments, the imaging device is provided with an insert that can be inserted between the first chip assembly 14 and the force-applying member 311, and the insert not only plays a role in positioning the developing box 100 / processing box C, but also plays a guiding role during the installation and disassembly process of the combination of the developing box 100 and the drum frame 200 / processing box C, so that the processing box C can accurately reach the predetermined installation position in the imaging device; in some embodiments, the first chip assembly 14 can also be combined with the force-applying member 311, for example, the first support portion 142 is formed integrally with the force-applying member 311.

[0077] Conversely, the position of the force-applying member 311 can be changed according to design requirements, as long as the force-applying member 311 can apply a force to the transmission member 41. For example, along the up and down directions, when the force-applying member 311 is arranged further downward, the force applied by the force-applying member 311 to the transmission member 41 will become greater, and accordingly, through the pushing portion 41b and the connecting member 44, the upward movement of the second chip assembly 25 / the second chip 43 will also be greater.

[0078] In some embodiments, before the force-applying member 311 comes into contact with the force-bearing portion 41a, the transmission member 41 can also be set to a state parallel to the third direction. At this time, along the third direction, the force-bearing portion 41a and the forced pushing portion 41b are basically flush. When the force-applying member 311 abuts against the force-bearing member 41, the forced pushing portion 41b moves upward, and at the same time forces the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip to move from a non-operating position to a working position.

[0079] The chip structure 3 can also be divided according to the location of each component, such as Figure 1As shown, the chip mechanism 3 includes a first part 31 arranged on the developing box 100 and a second part 32 arranged on the drum frame 200, wherein at least one of the first part 31 and the second part 32 is provided with a chip, preferably, a first chip assembly 14 is provided in the first part 31, and a second chip assembly 25 is provided in the second part 32. As the developing box 100 is installed toward the drum frame 200, the first part 31 applies a force to the second part 32, so that at least a part of the second part 32 (the second chip 43 / the second chip assembly 25 / the electrical contact part of the second chip) moves from the first position to the second position.

[0080] The drum shell 21 includes a side plate 21a located on the driving side C1, and the second part 32 is arranged on the side plate 21a. Along the third direction, the first chip assembly 14 and the second chip assembly 25 are arranged at intervals, and at least a part of the connecting assembly is located between the first chip assembly 14 and the second chip assembly 25. The first chip assembly 14 is located in front of the second chip assembly 25, or, along the third direction, the first chip assembly 14 is located between the developing roller 12 and the second chip assembly 25, or, along the third direction, the first chip assembly 14 is located between the driving force receiving member 13 and the second chip assembly 25, that is, the second chip assembly 25 is closer to the rear of the developing box 100 / processing box C than the first chip assembly 14.

[0081] In some embodiments, the chip mechanism 3 is entirely arranged on the driving side C1, so that the overall structure of the chip mechanism 3 becomes simple, especially the force-applying member 311 can directly apply force to the force-bearing portion 41a, and the transmission member 41 can directly transmit the force to the connecting member 44; further, the first chip assembly 14 is configured not to move as the developing box 100 is installed toward the drum frame 200 or removed from the drum frame 200, or in other words, the first chip assembly 14 is configured not to directly apply force to the transmission member 41, which makes the position of the first chip assembly 14 relative to the developing housing 1 does not change, and at the same time, the first chip assembly 14 does not need to cooperate with other components in the chip mechanism 3. For the transmission member 41 and the second chip assembly 25, as long as the transmission member 41 can receive the force applied by the force-applying member 311 and transmit the force to the second chip assembly 25, so that the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the non-operating position to the operable position, it can be seen that the matching accuracy requirements of the components in the chip mechanism 3 can be reduced.

[0082] As described above, the electrical contact portion 3 of the second chip component 25 / second chip 4 / second chip can be moved from the first position to the second position in at least any one of the first direction, the second direction and the third direction, that is, the electrical contact portion of the second chip component 25 / second chip 43 / second chip can be moved in at least any one of the first direction, the second direction and the third direction from a position where it cannot be electrically connected with the corresponding contact pin (second contact pin) in the device to a position where the electrical contact portion of the second chip component 25 / second chip 43 / second chip can be electrically connected with the corresponding contact pin (second contact pin) in the device, or in other words, the movement causes the electrical contact portion of the second chip component 25 / second chip 43 / second chip to move from a non-operable position to an operable position, and its operation The movement mode can be rotation or movement. In this embodiment, along the second direction, the second position is higher than the first position, that is, the second position is located above the first position; for the transmission member 41, its movement mode can also be rotation or movement. This embodiment mainly introduces the movement of the transmission member 41 in a rotation manner around the axis L2 extending along the first direction. In some embodiments, the transmission member 41 can also be configured to move along the first direction / second direction / third direction. For example, a mutually matching inclined surface is provided between the force-applying member 311 and the transmission member 41. When the force-applying member 311 moves downward, the transmission member 41 is pushed along the predetermined direction through the inclined surface, and then the forced pushing portion 41b transmits the force to the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip.

[0083] [Example 2]

[0084] Figure 4 It is a stereoscopic view of the developing box and the drum frame in the processing box involved in the second embodiment of the utility model before being combined with each other.

[0085] Different from the first embodiment, the force applying member 311 and the transmission member 41 in this embodiment are in flexible contact, such as Figure 4 As shown, the force-applying member 311 includes a fixed plate 3111 and a flexible member 3112 arranged on the fixed plate 3111, and the flexible member 3112 faces the transfer member 41. As the developing box 100 is installed, the flexible member 3112 will first contact the transfer member 41, and as the developing box 100 continues to be installed, the flexible member 3112 will undergo elastic deformation. At the same time, the flexible member 3112 will also transfer the force to the transfer member 41.

[0086] The setting of the flexible member 3112 makes the force-bearing process of the transmission member 41 smoother, and is used to buffer the force applied by the force-applying member 311. Therefore, the state of the transmission member 41 will not change suddenly. Correspondingly, the process of the second chip assembly 25 / second chip 43 moving from the non-operating position to the operable position is also smoother.

[0087] It is feasible that the flexible member 3112 is a sponge, rubber, spring, etc. fixed to the fixed plate 3111 .

[0088] [Example 3]

[0089] Figure 5 It is a three-dimensional diagram of the developing box and the drum frame in the processing box involved in the third embodiment of the present utility model before being combined with each other.

[0090] Different from the second embodiment, the flexible member 3112 is also provided in this embodiment, but the flexible member 3112 is provided as a torsion spring. Figure 5 As shown, one end of the torsion spring abuts against the fixed plate 3111, and the other end is suspended. As the developing box 100 is installed, the other end of the torsion spring abuts against the transmission member 41 to transmit the force.

[0091] In this embodiment, the torsion spring can be installed via the installation shaft, and finally, the torsion spring can be more stably positioned on the end cover 11 / developing housing 1.

[0092] [Example 4]

[0093] Fig. 6A It is a three-dimensional diagram of the developing box and the drum frame in the processing box involved in the fourth embodiment of the utility model before they are combined with each other; Figure 6B Observe along the first direction Fig. 6A A side view of the middle processing box; Fig. 7A It is a three-dimensional diagram of the developer box and the drum frame in the processing box involved in the fourth embodiment of the utility model after being combined with each other; Figure 7B Observe along the first direction Fig. 7A Side view of the processing box in the figure.

[0094] In the above-mentioned corresponding feasible embodiments, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves from bottom to top when it moves from the first position to the second position along the second direction, and for the limiting member 46 / drum shell 21, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves from the retracted state to the extended state, and then when the developing box 100 is taken out of the drum frame 200, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves from the second position to the first position along the second direction, and moves from top to bottom, and for the limiting member 46 / drum shell 21, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves from the extended state to the retracted state.

[0095] In this embodiment, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip is also configured to move along the second direction, and the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip can adopt any one of the movement methods in the above embodiments. Before the developing box 100 is installed toward the drum frame 200, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip is in a first position where it exceeds the limit member 46 and cannot work. As the developing box 100 is installed, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves downward. When the developing box 100 reaches the predetermined installation position in the drum frame 200, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip is in a second workable position. When the developing box 100 is taken out of the drum frame 200, the electrical contact portion of the second chip assembly 25 / second chip 43 / second chip moves from the second position to the first position. That is to say, in this embodiment, when the developing box 100 is installed toward the drum frame 200, the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the first position toward the second position, specifically, along the second direction, the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from top to bottom, and when the developing box 100 is taken out of the drum frame 200, the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the second position toward the first position, specifically, along the second direction, the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from bottom to top.

[0096] like Fig. 6A As shown, the second chip assembly 25 / second chip 43 is combined with the transmission member A41 through the connecting member 44. Similar to the above embodiment, the connecting member 44 in this embodiment can be set as an elastic member or a non-elastic member, as long as the force of the transmission member A41 can be transmitted to the second chip assembly 25 / second chip 43.

[0097] The transmission member A41 in this embodiment includes a base A41c combined with the drum shell 21, a movable part A41a arranged in the base, and a reset part A41b located between the movable part and the base. Under the reset force of the reset part A41b, the movable part A41a can move relative to the base A41c. Specifically, the movable part A41a is set to move along the second direction, and the reset part A41b is set to be an elastic member, which forces the movable part A41a to move upward.

[0098] like Fig. 6A and Figure 6BAs shown, before the developing box 100 is installed on the drum frame 200, the elastic member A41b causes the movable part A41a to be in an upwardly pushed state, and then the movable part A41a pushes the connecting member 44 and the second chip assembly 25 / the second chip 43 / the electrical contact part of the second chip to be in the first position that exceeds the limit member 46 and cannot work.

[0099] like Fig. 7A and Figure 7B As shown, as the developing box 100 is installed toward the drum frame 200, the force-applying member 311 begins to push the movable part A41a downward, and the elastic member A41b undergoes elastic deformation, and accordingly, the connecting member 44 together with the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip also moves downward, so that the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip moves from the first position to the second position, that is, the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the non-operable position to the operable position.

[0100] When the developing box 100 is taken out from the drum frame 200, the force-applying member 311 gradually stops applying force to the movable part A41a, and the elastic member A41b releases the elastic force, forcing the movable part A41a to gradually move upward. At the same time, the connecting member 44 and the electrical contact part of the second chip assembly 25 / the second chip 43 / the second chip also gradually return from the second position to the first position, that is, the electrical contact part of the second chip assembly 25 / the second chip 43 / the second chip moves from the workable position to the non-workable position.

[0101] [Example 5]

[0102] Figure 8 It is a three-dimensional diagram of the developer box and the drum frame in the processing box involved in the fifth embodiment of the present utility model after being combined with each other.

[0103] Different from the first embodiment, in this embodiment, the first chip assembly 14 is not arranged on the same side as the second chip assembly 43. Figure 8 As shown, along the first direction, the first chip assembly 14 is arranged on the non-driving side C2, and the second chip assembly 25 is arranged on the driving side C1, so that the arrangement density of the contact pins used for electrical communication with the first chip assembly 14 and the second chip assembly 43 in the imaging device can be reduced.

[0104] For the first chip component 14, this arrangement is also beneficial to reducing the impact of the vibration generated by the driving force receiving member 13 during operation on the first chip component 14. As mentioned above, along the third direction, the first chip component 14 is closer to the driving force receiving member 13 than the second chip component 25. If the first chip component 14 closer to the driving force receiving member 13 is set to the non-driving side C2, then the vibration of the driving force receiving member 13 will gradually attenuate during the process of being transmitted to the non-driving side C2, thereby reducing the impact on the first chip component 14.

[0105] [Example 6]

[0106] Fig. 9 It is a three-dimensional diagram of the development box and the drum frame in the processing box involved in the sixth embodiment of the utility model after being combined with each other; Fig.10 yes Fig. 9 A magnified schematic diagram of the local R in the figure.

[0107] As described in the first embodiment, at least one of the first part 31 and the second part 32 in the chip mechanism 3 is provided with a chip for electrically connecting to the imaging device. The above embodiment describes a structure in which both the first part 31 and the second part 32 are provided with chips. This embodiment will describe a structure in which one of the first part 31 and the second part 32 is provided with a chip.

[0108] like Fig.10 As shown, the chip mechanism 3 is only provided with the first chip 143, and the electrical contact part in the first chip 143 is divided into a first electrical contact part 143b and a second electrical contact part 143c, wherein the first electrical contact part 143b plays the role of the electrical contact part in the above-mentioned developing box, and the second electrical contact part 143c plays the role of the electrical contact part in the above-mentioned drum frame, that is, the first chip 143 in this embodiment can store parameter information about the developing box 100 and parameter information about the drum frame 200 at the same time, so that the second chip 43 is not necessary to be set in the drum frame 200; conversely, the chip mechanism 3 can also only be provided with the second chip 43, and the first chip 143 can be omitted. For the end user, when replacing a developing box 100 without the first chip 143, it is obvious that the cost of the developing box 100 without the first chip 143 must be lower, and thus, the use cost of the end user is also reduced.

[0109] Fig.10The diagram shows a situation where only the first chip 143 is provided, and the chip mechanism 3 further includes a conductor 144 electrically contacting the second electrical contact portion 143c, wherein one end 144a of the conductor 144 is in contact with the second electrical contact portion 143c, and the other end 144b is used to electrically connect with a contact pin (first contact pin) in the imaging device that is originally used to electrically connect with the electrical contact portion (second electrical contact portion) in the drum frame. In this way, only the first chip 143 is provided, and the second electrical contact portion 143c is provided in the first chip 143, and a conductor 144 electrically contacting the second electrical contact portion 143c is provided. Preferably, the conductor 144 is supported by the first support portion 142. Finally, the imaging device can obtain information about the developing box 100 and the drum frame 200.

[0110] [Other transformation methods]

[0111] Based on the inventive concept of the utility model, in the above-mentioned corresponding feasible embodiments, the process of the force-applying member 311 applying force to the transmission member 41 / A41 is completed by direct contact between the force-applying member 311 and the transmission member 41 / A41. In some embodiments, magnetic members may be respectively arranged in the force-applying member 311 and the transmission member 41 / A41, so that a magnetic force is generated between the force-applying member 311 and the transmission member 41 / A41, thereby driving the transmission member 41 / A41 to move.

[0112] For example, components that can generate magnetic repulsion force are respectively installed in the force-applying member 311 and the transmission member 41 / A41. As the developing box 100 is installed toward the drum frame 200, a repulsion force is generated between the force-applying member 311 and the transmission member 41 / A41, and the rod member 41 rotates around the axis L2, so that the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip moves from bottom to top, or the movable portion A41a moves downward along the second direction, so that the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip moves from top to bottom, and then the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the first position to the second position. When the developing box 100 is taken out of the drum frame 200, the repulsion force gradually decreases, and the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip resets from the second position to the first position.

[0113] In some embodiments, components that can generate magnetic attraction can also be installed in the force-applying member 311 and the transmission member 41 / A41 respectively. As the developing box 100 is installed toward the drum frame 200, attraction is generated between the force-applying member 311 and the transmission member 41 / A41, and the rod 41 rotates around the axis L2, so that the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip moves from top to bottom, or the movable portion A41a moves upward along the second direction, so that the second chip assembly 25 / the second chip 43 / the electrical contact portion of the second chip moves from bottom to top, and then the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip moves from the first position to the second position. When the developing box 100 is taken out of the drum frame 200, the attraction gradually decreases, and the electrical contact portion of the second chip assembly 25 / the second chip 43 / the second chip is reset from the second position to the first position.

[0114] [Example 7]

[0115] like Figures 11 to 13 As shown, the developing box B100 includes a developing roller B110 and a housing B120, which is installed on the drawer B030 of the printer B010 when in use. The developing roller B110 extends along the width direction (first direction) B001 of the developing box B100 and is rotatably installed on the housing B120; the housing B120 is provided with an elastic part B121 for abutting against the pressing part B021 of the housing B020 of the printer B010; when the drawer B030 is pushed into the printer B010, the pressing part B021 can apply a downward component force to the developing box B100 by pressing the elastic part B121, so that the developing box B100 is completely loaded into the drawer B030.

[0116] The elastic part B121 of the developer box B100 does not abut against the exposure unit B040 of the printer B010, but only abuts against the housing B020 of the printer B010. When the developer box B100 is loaded into the drawer B030, the user does not need to press down the developer box B100 intentionally. When the drawer is pushed into the printer B010, the developer box B100 will not directly impact the exposure unit B040, which is beneficial to extend the life of the printer B010, eliminate the need for manual operation by the user, and improve the user experience.

[0117] Preferably, the elastic portion B121 is a handle provided on the upper side of the developing box B100, and the handle is provided on both sides of the shell B120 along the width direction (first direction) of the developing box B100, and the extrusion portion B021 is the upper wall surface B023 of the channel B022 on the casing B020 for accommodating the drawer B030.

[0118] Preferably, the number of the handles is not limited to two but may be three or more. The handles are made of elastic material. The handles are not limited to an inverted V-shape but may be other shapes.

[0119] [Embodiment 8]

[0120] like Figures 14 to 17 As shown, the developing box B200 includes a developing roller B210 and a housing B220, which is installed on the drawer B030 of the printer B010 when in use. The developing roller B210 extends along the width direction (first direction) B001 of the developing box B200 and is rotatably installed on the housing B220; the housing B220 is provided with an elastic part B221 for abutting against the pressing part of the housing B020 of the printer B010; when the drawer B030 is pushed into the printer B010, the pressing part can apply a downward component force to the developing box B200 by pressing the elastic part B221, so that the developing box B200 is completely loaded into the drawer B030.

[0121] The elastic part B221 of the developer box B200 does not abut against the exposure unit B040 of the printer B010, but only abuts against the housing B020 of the printer B010. When the developer box B100 is loaded into the drawer B030, the user does not need to press down the developer box B200 intentionally. When the drawer B030 is pushed into the printer B010, the developer box B200 will not directly impact the exposure unit B040, which is beneficial to extend the life of the printer B010.

[0122] Preferably, the elastic part B221 includes a slider B222 that slides along the width direction (first direction) B001 of the developing box B200 and a spring B223 that is arranged between the slider B222 and the housing B220. The slider B222 is installed on the housing B220 through a slideway B226 that extends along the width direction (first direction) B001. The elastic part B221 is arranged on both sides of the housing B220 along the width direction (first direction) B001 of the developing box B200. The restoring force of the spring B223 pushes the slider B222 away from the center of the developing box B200 along the width direction (first direction) B001. Along the push-pull direction of the drawer B030, that is, the length direction (second direction) B002 of the developing box B200, before the drawer B030 is loaded into the printer B010, a guide surface B224 is provided on the side of the slider B222 close to the printer B010.

[0123] The pressing part is a shoulder B024 of the passage B022 on the housing B020 for accommodating the drawer B030. The shoulder B024 is arranged on both sides of the housing B220 along the width direction (first direction) of the developing box B200.

[0124] When the drawer B030 is loaded into the printer B010 along the length direction (second direction) B002, the shoulder B024 presses the guide surface B224 to make the slider B222 overcome the restoring force of the spring B223 and move closer to the center of the developing box B200 along the width direction (first direction) B001. The shoulder B024 applies a downward force to the developing box B200 through the guide surface B224, so that the developing box B200 is loaded into the drawer B030.

[0125] Preferably, an inclined surface B225 is formed on the slider B222. Before the drawer B030 is installed in the printer B010 along the length direction (second direction) B002, the inclined surface B225 is located on the side of the guide surface B224 away from the center of the printer B010. After the drawer B030 is installed in the printer B010 along the length direction (second direction) B002, the shoulder B024 abuts against the inclined surface B225, so that the spring B223 maintains a compressed state. Obviously, the elastic part B421 can also be replaced by other elastic materials such as rubber.

[0126] This solution has a simple structure. The user does not need to deliberately press down the developer box B200. It is easy to install and does not require manual pressing operations, thereby improving the user experience.

[0127] [Example 9]

[0128] like Figures 18 to 20 As shown, the developing box B300 includes a developing roller B310 and a housing B320, which is installed on the drawer B030 of the printer B010 when in use. The developing roller B310 extends along the width direction (first direction) B001 of the developing box B300 and is rotatably installed on the housing B320; the housing B320 is provided with an elastic part B321 for abutting against the pressing part B021 of the housing B020 of the printer B010; when the drawer B030 is pushed into the printer B010, the pressing part B021 can apply a downward component force to the developing box B300 by pressing the elastic part B321, so that the developing box B200 is completely loaded into the drawer B030.

[0129] The elastic portion B321 is hinged to the shell B320 via an axis B322 extending along the length direction (second direction) B002 of the developing box B300, and the elastic portion B321 is provided on both sides of the shell B320 along the width direction (first direction) B001 of the developing box B300.

[0130] The shaft B322 is not limited to being formed on the elastic part B321, but can also be detachably installed on the shell B320.

[0131] Preferably, a torsion spring B323 as a reset member is provided between the elastic portion B321 and the shell B320, one end of the torsion spring B323 abuts against the shell B320, and the other end abuts against the boss B324 on the elastic portion B321. The elastic portion B321 swings downward under the reset force of the torsion spring B323 until it abuts against the limit surface B325 on the shell B320. At this time, the elastic portion B321 is roughly parallel to the width direction (first direction) B001. Obviously, the reset member is not limited to the torsion spring B323, but can also be other forms of springs or elastomers. The torsion spring B323 as a reset member is not necessary.

[0132] When the developing box B300 is downwardly loaded into the drawer B030, the walls B031 on both sides of the drawer B030 along the width direction (first direction) B001 force the elastic part B321 to swing upward to overcome the restoring force of the torsion spring B323. When the drawer B030 is pushed into the printer B010, the other end B326 of the elastic part B321 opposite to the shaft B322 abuts against the pressing part B021 of the printer B010.

[0133] Preferably, when the developing box B300 is loaded downward into the drawer B030, the elastic part B321 swings up to a roughly vertical position.

[0134] Preferably, the extrusion portion B021 is an upper wall surface B023 of a channel B022 on the housing B020 for accommodating the drawer B030. Before the drawer B030 is pushed into the printer B010, a guide surface B327 is provided on the side of the elastic body B321 close to the printer B010. The guide surface B327 reduces the resistance when the drawer B030 is pushed into the printer B010.

[0135] The elastic part B321 of the developer box B300 does not abut against the exposure unit B040 of the printer B010, but only abuts against the housing B020 of the printer B010. When the developer box B300 is loaded into the drawer B030, the user does not need to press the developer box B300 downwards intentionally. When the drawer B030 is pushed into the printer B010, the developer box B300 will not directly impact the exposure unit B040, which is beneficial to extend the life of the printer B010.

[0136] See also Fig.21 As an improvement, the other end B326 of the elastic part B321 opposite to the shaft B322 is provided with an opening B328 extending along the length direction (second direction) B002. Along the length direction (second direction) B002, before the drawer B030 is pushed into the printer B010, the opening B328 is located on the side of the elastic part B321 away from the printer B010. The opening B328 is conducive to reducing the stiffness coefficient of the elastic part B321.

[0137] [Example 10]

[0138] like Figure 22 to Figure 26 As shown, the developing box B400 includes a developing roller B410 and a housing B420, which is installed on the drawer B030 of the printer B010 when in use. The developing roller B410 extends along the width direction (first direction) B001 of the developing box B400 and is rotatably installed on the housing B420; the housing B420 is provided with an elastic part B421 for abutting against the pressing part of the housing B020 of the printer B010; when the developing box B400 is downwardly loaded into the drawer B030, the pressing part can apply a downward component force to the developing box B400 by pressing the elastic part B421, so that the developing box B400 is locked on the drawer B030.

[0139] The elastic portion B421 of the developing box B400 does not abut against the exposure unit B040 of the printer B010. When the drawer pusher B030 is inserted into the printer B010, the developing box B400 will not cause direct impact on the exposure unit B040, which is beneficial to extending the life of the printer B010.

[0140] Preferably, the elastic part B421 includes a slider B422 that slides along the width direction (first direction) B001 of the developing box B400 and a spring B423 that is arranged between the slider B422 and the housing B420. The slider B422 is installed on the housing B420 through a slideway B426 that extends along the width direction (first direction) B001. The elastic part B421 is arranged on both sides of the housing B420 along the width direction (first direction) B001 of the developing box B400. The restoring force of the spring B423 pushes the slider B422 along the width direction (first direction) B001 to a direction away from the center of the developing box B400.

[0141] The wall body B031 on both sides of the drawer B030 along the width direction (first direction) B001 is respectively provided with grooves B032 corresponding to the slider B422. The lower side of the slider B422 is provided with a first guide surface B425, and the upper side of the slider B422 is provided with a second guide surface B426.

[0142] When the developing box B400 is loaded downward into the drawer B030, the first guide surface B425 abuts against the upper end B033 of the wall body B031, and the slider B422 retracts toward the center of the developing box B400 under the guidance of the first guide surface B425. When the developing box B400 is pressed down to a predetermined position, the slider B422 extends toward the groove B032, and the second guide surface B426 abuts against the upper side surface B034 of the groove B032 to prevent the developing box B400 from popping out of the drawer B030. The upper side surface B034 serves as the extrusion portion of this embodiment. When the developing box B400 needs to be disassembled, the developing box B400 is lifted up by the handle B427, and under the guidance of the second guide surface B426, the slider B422 retracts toward the center of the developing box B400, thereby pulling out the developing box B400.

[0143] Obviously, the elastic part B421 can also be replaced by other elastic materials such as rubber.

[0144] join Fig. 27 As an improvement, a second groove B035 is provided on the wall B031 of the drawer B030 so as to increase the activity space of the slider B422 and reduce the resistance to pulling out the developing box B400.

[0145] See also Fig.28 and Fig.29 As a further improvement, a chip B501 for electrically connecting to the electrical contact B036 on the drawer B030 is fixed on the shell B520. Furthermore, the chip B501 extends along the height direction B003 of the developing box B500. The electrical contact B036 is electrically connected to the printer control board. After the developing box B500 is loaded into the drawer B030, the chip B501 is directly electrically connected to the electrical contact B036, and there is no retraction process. The solution has a simple and practical structure, can prevent the chip from collision and wear during installation, ensure the stability and reliability of the contact, and improve the accuracy of information transmission.

[0146] The technical solution of fixing the chip on the developer box housing is not limited to being an improvement of the tenth embodiment, but is also applicable to the other aforementioned embodiments.
