The rotating body is used to receive the driving force of an external driving member and drive the counting member to interact with a detection member in an imaging device to perform a counting operation. When counting is completed, at least one of the rotating body and the counting member remains stationary. Along the rotation direction of the rotating body, a counting area and a non-counting area are adjacently arranged on the circumference of the rotating body. When the counting member is in a counting state, the counting area is opposite to the driving member. When the counting member completes counting, the non-counting area is opposite to the driving member. The counting area includes at least one driving part and at least one cutting part that are adjacently arranged. When the driving part is opposite to the driving member, the rotating body can receive the driving force of the driving member and drive the counting member to rotate. When the cutting part is opposite to the driving member, the rotating body cannot receive the driving force of the driving member and remains stationary. Through the rotating body, the average rotation speed of the counting member is reduced, and the counting member becomes universal.

Description

[0001] The present invention claims the priority of the Chinese prior application filed by the applicant on November 19, 2021, with the invention name “Developer Box” and application number CN202122860826.3, and all the contents of the prior application are cited in this application. Technical Field

[0002] The invention relates to the field of electronic photographic imaging, and in particular to a developing box detachably installed in an electronic photographic imaging device, and a counting assembly and a rotating body located in the developing box. Background Art

[0003] A developer cartridge is a consumable product used in imaging devices such as laser printers or copiers, which stores the toner required for imaging. When working, the power receiving member in the developer cartridge receives the driving force from the imaging device, and the powder feeding member and the developing member installed in the developer cartridge rotate in a predetermined direction and at a predetermined speed. The powder feeding member is used to supply toner to the surface of the developing member, and the developing member is used to supply toner to the surface of the photosensitive member where an electrostatic latent image is formed, so that the electrostatic latent image is developed.

[0004] In order to enable the imaging device to accurately grasp the usage status of the developing cartridge, a component called a "counting component" is provided in the existing developing cartridge. When the developing cartridge is first installed in the imaging device and starts working, the counting component and the detection component in the imaging device touch each other. Through parameters such as the touching duration, touching interval, and touching times of the counting component and the detection component, the imaging device can learn information such as the service life and model of the developing cartridge. Summary of the invention

[0005] In practice, imaging device manufacturers will differentiate the developer cartridge models suitable for the imaging device according to the regions where the imaging device is sold. The appearance and size of these developer cartridges are basically the same, and the difference lies in the above-mentioned parameters of the counting components. In other words, the counting components corresponding to developer cartridges in different regions / models are different, which means that the developer cartridge manufacturers must prepare the materials required for the production of these models separately.

[0006] To this end, one of the purposes of the present invention is to provide a component that can make the counting assembly compatible with various types of developer boxes by simply adjusting the component structure or replacing the component.

[0007] Specifically, the component is a rotating body, which is used to receive the driving force of an external driving member and drive the counting member to interact with the detection member in the imaging device to perform a counting operation. When the counting is completed, at least one of the rotating body and the counting member remains stationary; along the rotation direction of the rotating body, the counting area and the non-counting area are adjacently arranged on the circumference of the rotating body. When the counting member is in a counting state, the counting area is opposite to the driving member. When the counting member completes counting, the non-counting area is opposite to the driving member. The counting area includes at least one driving part and at least one adjacently arranged. When the driving part is opposite to the driving member, the rotating body can receive the driving force of the driving member and drive the counting member to rotate. When it is opposite to the driving member, the rotating body cannot receive the driving force of the driving member and remains stationary. For a counting member that originally requires a faster average rotation speed, the average rotation speed of the counting member can be reduced through the rotating body, making the counting member universal.

[0008] In which, the rotating body also includes a triggered member arranged therein. When the triggered member is triggered by an external triggering member, the triggered member drives the rotating body to rotate, so that the driving member is converted from being relative to the driving member to being relative to the driving part; when observed along the rotation axis of the rotating body, the triggered member is relative to the driving member, and preferably, along the rotation direction of the rotating body, the triggered member is roughly located in the middle position of the corresponding arc.

[0009] As one embodiment, the driving unit is set to be multiple, and is located between the multiple driving units along the rotation direction of the rotating body. Two of the multiple driving units are respectively located on both sides of the non-counting area. Further, it is also set to be multiple, and one driving unit is located between the multiple driving units along the rotation direction of the rotating body.

[0010] As another embodiment, the driving parts and are both provided as one, and along the rotation direction of the rotating body, the driving parts and are both adjacent to the counting area.

[0011] Accordingly, the present invention also provides a counting assembly, which includes a counting member and a rotating body as described above, and when the developing box is working, the rotating body is driven by the driving force supplied by the imaging device.

[0012] Furthermore, the present invention also provides a developing box, which can be detachably installed in an imaging device provided with a detection component, including a shell for accommodating toner and a counting assembly as described above, and the counting assembly can be rotatably installed at the longitudinal end of the shell.

[0013] The counting component also includes a supporting body combined with the rotating body. A plurality of positioning protrusions arranged along the circumferential direction of the rotating body are provided on the shell. The positioning protrusions are in contact with the circumferential inner surface or outer surface of the supporting body. Compared with the existing supporting method of the rotating body, the rotating body involved in the present invention has a larger supported circumferential area and becomes more stable.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] [Overall structure of the developer cartridge]

[0041] Figure 11 is a three-dimensional diagram of a developing box involved in the present invention. The developing box C has a front-to-back direction, a left-to-right direction, and an up-to-down direction as shown in the figure, and can be installed to the imaging device in the front direction 101 and taken out in the rear direction 102 along the front-to-back direction. The end for receiving the driving force from the imaging device is called the driving end 103, which corresponds to the left side in the figure, and the end for receiving the power from the imaging device is called the conductive end 104, which corresponds to the right side in the figure.

[0042] The developing box C includes a shell 1 for accommodating toner, a rotating member 2 rotatably mounted in the shell 1, a driving force receiving member 3 located at the driving end 103, a counting assembly 5 arranged on the same side as the driving force receiving member 3, and a gear set 4 for transmitting driving force between the driving force receiving member 3 and the counting assembly 5. The driving force receiving member 3 is used to receive driving force from the imaging device and drive the rotating member 2 and the counting assembly 5 to work; the rotating member 2 extends along the left-right direction / length direction / longitudinal direction of the developing box and is supported by the shell 1 in a rotatable manner. Specifically, the developing member 21 for supplying toner to the outside is a kind of rotating member, and the powder feeding member 22 (such as the powder feeding member 22) that contacts the developing member 21 and is used to feed toner to the developing member 21 Figure 4 The stirring member 23 (shown) is also a rotating member and is used to stir the carbon powder to prevent it from agglomerating. At the same time, the stirring member 23 that transports the carbon powder to the powder feeding member 22 is also a rotating member.

[0043] like Figure 1 As shown, the developing member 21 is arranged near the front of the developing box C, and along the front-to-back direction, the driving force receiving member 3 is located behind the developing member 21, and the counting component 5 is located behind the driving force receiving member 3. Therefore, the driving force receiving member 3 is closer to the developing member 21 than the counting component 5. In comparison, during the operation of the developing box C, the resistance encountered by the developing member 21 during rotation is much greater than the resistance encountered by the counting component 5 during rotation. At this time, the driving force receiving member 3 is arranged closer to the developing member 21, which can ensure that the driving force transmission between the driving force receiving member 3 and the developing member 21 is more efficient.

[0044] Continue as Figure 1 As shown, the developing box C also includes a driving end cover 11 installed at the driving end 103, and the driving force receiving member 3 and the counting assembly 5 are both exposed through the driving end cover 11. Therefore, when the driving force is transmitted to the counting assembly 5, the counting member 51 in the counting assembly 5 can interact with the detection component in the imaging device.

[0045] [Example 1]

[0046] Figure 2 1 is a schematic diagram of partial component decomposition of a driving end of a developing cartridge according to a first embodiment of the present invention; Figure 3 is a partial exploded schematic diagram of the conductive end of the developing box involved in the first embodiment of the present invention; Figure 4is a cross-sectional view of the developing cartridge according to the first embodiment of the present invention cut along a plane parallel to the front-rear direction thereof; Figure 5 It is an overall side view of the developing box involved in the first embodiment of the present invention when viewed from the bottom to the top.

[0047] like Figure 2 As shown, the shell 1 includes a bottom shell 1a and a surface cover 1b which are combined with each other, and the toner chamber 10 is located between the bottom shell 1a and the surface cover 1b. The bottom shell 1a has a left side wall 1a1 located at the driving end 103 and a right side wall 1a2 located at the conductive end 104. The toner chamber 10 is located between the left side wall 1a1 and the right side wall 1a2. The developing part 21, the powder feeding part 22 and the stirring part 23 are supported by the left side wall 1a1 and the right side wall 1a2 respectively; the powder filling port 13 is arranged on the left side wall 1a1 or the right side wall 1a2. When the toner in the toner chamber 10 is consumed, the user can add new toner to the toner chamber 10 through the powder filling port 13.

[0048] The gear group 4 includes a first gear 41 combined with the driving force receiving member 3, a second gear 42 and a third gear 43 respectively located at the ends of the developing member 21 and the powder feeding member 22, and a fourth gear 44 combined with the counting component 5, so that the second gear 42 can be called a developing member gear, and the third gear 43 can be called a powder feeding member gear, wherein the first gear 41 is meshed with the second gear 42 and the third gear 43 at the same time, and along the front-to-back direction, the first gear 41 and the fourth gear 44 are spaced from each other, and the driving force is transmitted between the two through an intermediate transmission component; the first gear 41 and the driving force receiving member 3 can be formed integrally or separately, as long as the driving force of the driving force receiving member 3 can be stably transmitted to the first gear 41, preferably, the first gear 41 is coaxially arranged with the driving force receiving member 3.

[0049] In this embodiment, the rotation axis L23 of the stirring member 23 is parallel to the rotation axis of the developing member 21, the fourth gear 44 is coaxially arranged with the stirring member 23 and can be called a stirring member gear, and the driving force received by the driving force receiving member 3 is first transmitted from the driving end 103 to the conductive end 104, and then transmitted back from the conductive end 104 to the driving end 103. Figure 3As shown, at least one of the developing member 21 and the powder feeding member 22 can be used to transmit the driving force from the driving end 103 to the conductive end 104. Accordingly, the gear set 4 also includes a fifth gear 45 arranged at the conductive end 104 and a seventh gear 47 arranged coaxially with the stirring member 23. The connection between the fifth gear 45 and the seventh gear 47 can be adjusted according to the rotation direction requirements of the counting component 5, the size requirements of the developing box, etc. For example, the two can be directly meshed to achieve connection, or can be connected through one or more sixth gears 46. For this embodiment, the seventh gear 47 located at the conductive end 104 can be regarded as the driving force input gear of the stirring member 23, and the fourth gear 44 located at the driving end 103 can be regarded as the driving force output gear. For the counting component 5, the fourth gear 44 can be regarded as the driving gear.

[0050] like Figure 3 As shown, the developing box C also includes a conductive end cover 12 installed on the conductive end 104, and the fifth gear 45, the sixth gear 46 and the seventh gear 47 are all located between the right side wall 1a2 of the bottom shell and the conductive end cover and are protected. Therefore, the driving force received by the driving force receiving member 3 is first transmitted to the conductive end 104 through the developing member 21 and / or the powder feeding member 22, and then transmitted to the stirring member 23 through the fifth gear 45, the sixth gear 46 and the seventh gear 47, and finally transmitted to the fourth gear 44 by the stirring member 23, and then the counting component 5 is driven by the fourth gear 441 to work.

[0051] like Figure 5 As shown, the developer box C also includes a first forced pushing portion 14a and a second forced pushing portion 14b arranged on the left and right sides. When the developer box is installed, the first forced pushing portion 14a and the second forced pushing portion 14b receive a forced pushing force, thereby forcing the developer box C to remain at a predetermined position where the developer 21 contacts the photosensitive member (not shown). Optionally, the first forced pushing portion 14a and the second forced pushing portion 14b can be arranged on the end covers on the left and right sides, or can be formed by protruding from the left and right sides of the housing 1. Along the left and right directions, the first forced pushing portion 14a and the second forced pushing portion 14b are basically aligned (as shown in FIG. 1 ). Figure 4 (as shown by the middle dotted line), along the width direction / front-to-back direction / lateral direction of the developing box C, the first pushing portion 14a and the second pushing portion 14b are closer to the front 104 / developing member 21, and the pushing force can be more effectively transmitted to the developing member 21.

[0052] Fig. 6A is a side view of the driving end of the developing cartridge according to the first embodiment of the present invention when viewed from below to above; Figure 6B It is a cross-sectional view of the developing box involved in the first embodiment of the present invention, cut along a plane parallel to the front-rear direction thereof and passing through the driving force receiving member and the driving gear at the same time.

[0053] In this embodiment, the first forced pushing portion 14a is formed integrally with the driving end cover 11. Fig. 6A , the first forced pushing portion 14a is hidden together with the driving end cover 11. The counting assembly 5 includes a counting member 51 and a driven body 52 combined with each other and a forced pushing member 57 for forcing the driven body 52. ​​The driving gear 44 is combined with the driven body 52. ​​The driving force is sequentially transmitted to the counting member 51 through the driving gear 44 and the driven body 52. ​​The counting member 51 interacts with the detection component in the imaging device during the rotation process. Under the action of the forced pushing member 57, the driven body 52 and the driving gear 44 are well combined. Further, the counting assembly 5 also includes a supporting body 53 combined with the driven body 52. ​​Along the left and right directions, the supporting body 53 and the counting member 51 are respectively located on both sides of the driven body 52. ​​The supporting body 53, the driven body 52 and the counting member 51 can be collectively referred to as the counting part of the counting assembly 5, and the forced pushing member 57 can be referred to as the forced pushing part of the counting assembly 5. The counting part can be formed in one piece or in a split body, which is not limited here. In this embodiment, the counting part is installed by point support. As shown in the figure, the left side wall 1a1 is protruding with multiple positioning protrusions 17, and the multiple positioning protrusions 17 are arranged along the circumferential direction of the counting part / driven body 52. ​​The circumferential inner surface or outer surface of the support body 53 contacts the positioning protrusions 17 to realize the positioning of the counting part in the shell 1. Compared with the existing shaft hole matching method, the circumferential area of ​​the support body 53 is larger, making the rotation smoother.

[0054] Continue as Figure 2 As shown, the end cover 11 has an end cover body 110 and a first through hole 111, a second through hole 112 and an extension plate 113 arranged on the end cover body, the driving force receiving member 3 is exposed through the first through hole 111, and at least the counting member 51 in the counting assembly 5 is exposed through the second through hole 112. Furthermore, a plurality of auxiliary protrusions 114 are also provided on the side of the extension plate 113 facing the shell 1. When the end cover 11 is installed, the auxiliary protrusions 114 are combined with the counting member 51. At this time, both the left and right sides of the counting part are positioned, so that the stability of the counting part during the counting process is guaranteed.

[0055] As described above, the driving gear 44 is coaxial with the stirring member 23, and is driven by the stirring member 23 to transmit the driving force to the counting component 5. That is to say, as long as the driving gear 44 can receive the driving force of the stirring member 23 and transmit the driving force to the counting component 5 at the same time, for the counting component 5, the driving gear 44 can be regarded as the driving member of the counting component. Therefore, in the left and right directions, the distance between the driving gear 44 and the left side wall 1a1 bracket and the distance between the counting component 5 and the left side wall 1a1 can be shortened to the greatest extent, and the left and right dimensions of the developing box C and the driving gear 44 and the counting component 5 corresponding to the position can be reduced; even if the distance between the counting component 5 and the left side wall 1a1 cannot be changed due to the position of the detection component in the imaging device, the driven body 52 can be set at a position close to the left side wall 1a1, specifically, the left side surface 52a of the driven body 52 is close to the left side wall 1a1, which can also achieve the purpose of reducing the size of the developing box C.

[0056] For the existing developing box, at least one intermediate gear is provided between the first gear 41 and the driving gear 44, such as Fig. 6A As shown, along the left-right direction, the distance between the first gear 41 and the left side wall 1a1 is greater than the distance between the driven body 52 and the left side wall 1a1. Obviously, in order for the driving force to be transmitted from the first gear 41 to the driven body 52, the intermediate gear must be arranged to have at least two stages, and accordingly, the driving gear 44 also needs to be arranged to have two stages. At this time, the size of the developing box in the left-right direction, especially the position corresponding to the intermediate gear and the driving gear 44, cannot be reduced.

[0057] like Figure 6BAs shown, when cut along a plane parallel to the front-to-back direction and passing through the driving force receiving member and the driving gear at the same time, a portion of the first forced pushing portion 14a will be retained, the rotation center of the driving force receiving member 3 / first gear 41 is M, the rotation center of the stirring member 23 / driving gear 44 is N, and along the line MN connecting the two rotation centers, the maximum distance between the first gear 41 and the driving gear 44 is S3, the minimum distance is S2, and the distance between the two rotation centers is S1. The first forced pushing portion 14a is at least located in the area defined by the maximum distance S3. Furthermore, the first forced pushing portion 14a is located in the area defined by the distance S1 between the two rotation centers, and a portion of the first forced pushing portion 14a is opposite to the area defined by the minimum distance S2. In the area defined by the minimum distance S2, since no other components are set, the area is formed as a vacant area, which is beneficial for the first forced pushing portion 14a to adjust its position and shape in the vacant area as needed. For example, when two models of developer boxes have only a slightly different position of the first pushing portion 14a, the production mold of the developer box can be simplified, thereby reducing production costs and management costs; or, when a certain model of developer box requires a larger pushing force, a reinforcing portion that can strengthen the strength of the first pushing portion 14a can be provided in the vacant area.

[0058] On the other hand, the driving gear 44 only needs to be set at one level and is set close to the left side wall 1a1, and the diameter and the size of the driving gear 44 in the left and right directions are reduced; in the present embodiment, the first forced pushing portion 14a is set on the driving end cover 11, and along the left and right directions, the overlapping area between the first forced pushing portion 14a and the driving gear 44 can be reduced, or even no overlapping area appears, and during the assembly process of the developing box C, the interference between the driving end cover 11 and the driving gear 44 can be reduced or eliminated; in the following embodiment, when the first forced pushing portion 14a protrudes from the left side wall 1a1, there will be no interference between the driving gear 44 with a reduced diameter and the first forced pushing portion 14a, that is, on a plane perpendicular to the left and right directions, there is no overlap between the first forced pushing portion 14a and the driving gear 44.

[0059] In actual work, the counting assembly 5 needs to be disengaged from the driving gear 44 and remain stationary after counting is completed, and the driven body 52 is configured to have a toothless portion 522 (such as Figure 8 The first method is to use a "half-toothed gear" with a toothed portion 521 and a toothed portion 521. During the counting process, the toothed portion 521 is opposite to the driving gear 44. When the counting is completed, the toothless portion 522 is opposite to the driving gear 44. The driving body 52 is set to a full-toothed gear (such as Figure 6BAs shown), the second way is to set the counting member 51 and the driven body 52 to be combined in a detachable manner. During counting, the counting member 51 can receive the driving force of the driven body 52. ​​When counting is completed, the counting member 51 is disengaged from the driven body 52; the third way is to set at least one of the driving gear 44 and the driven body 52 to be movable along a moving direction intersecting the left and right directions. During counting, the driving gear 44 and the driven body 52 are combined with each other. When counting is completed, at least one of the driving gear 44 and the driven body 52 moves in the moving direction so that the two are disengaged.

[0060] The first method mentioned above places high demands on the accuracy of the driven body 52. ​​The second method requires that the counting member 51 and the driven body 52 be arranged in a separate form, which not only complicates the assembly process, but more importantly, is not conducive to maintaining the working stability of the counting assembly 5. When the third method is adopted, preferably, the driving gear 44 is arranged to be movable in the moving direction, and more preferably, the moving direction is orthogonal to the left and right directions. At the same time, since the driving gear 44 and the first forced pushing portion 14a are also separated from each other, as shown in FIG. Figure 6B As shown, a spacing area S4 is formed between the driving gear 44 and the first forced pushing portion 14a, so that the driving gear 44 has a larger movable space, and the device capable of moving the driving gear 44 will have a greater degree of design freedom.

[0061] It should be noted that no other components are set in the above-mentioned vacant areas and spacer areas, which means that no functional components are set, such as protrusions or slide grooves for supporting a certain component, etc. However, protrusions or grooves set due to the mold requirements of the product are allowed.

[0062] [Example 2]

[0063] Figure 7 The figure is an overall side view of the developer box according to the second embodiment of the present invention, in which the face cover is hidden and the developer box is viewed from the top to the bottom.

[0064] The present embodiment is different from the first embodiment in that when the driving force is transmitted from the conductive end 104 to the driving end 103, the stirring member 23 is no longer used, but a transmission shaft 24 parallel to the stirring member 23 is used, and the rotation axis L24 of the transmission shaft 24 is also parallel to the rotation axis of the developing member 21. Preferably, along the front-to-back direction, the transmission shaft 24 is closer to the front 101 than the stirring member 23, and the driving gear 44 is coaxially arranged with the transmission shaft 24, but there is still a vacant area between the driving gear 44 and the first gear 41.

[0065] like Figure 7As shown, the driving gear 44 is separated from the driven body 52 in the counting assembly, and the driving gear 44 is configured to be movable in the moving direction. Before the developing box C is installed, the driving gear 44 is separated from the driven body 52. ​​In this way, during the transportation of the developing box C, the driving gear 44 will neither touch the first gear 41 nor the driven body 52, thereby reducing the risk of damage to the driving gear 44, the first gear 41 and the driven body 52; during the installation process of the developing box C or when the developing box C is installed to the predetermined position and starts working, the driving gear 44 returns to the position combined with the driven body 52, so that the counting assembly 5 can receive the driving force required for counting. After the counting is completed, the driving gear 44 returns to the position separated from the driven body 52 again.

[0066] Similarly, in this embodiment, only one level of the driving gear 44 is required, and a spacing area S4 will be formed between the driving gear 44 and the first pushing portion 14a. The spacing area and the vacant area provide space for the movement of the driving gear 44, so that the device that can move the driving gear 44 will have greater design freedom.

[0067] As an alternative, whether the transmission shaft 24 transmits the driving force from the conductive end 104 to the driving end 103 can be controlled according to the stage of the counting component 5. When the counting component 5 needs to count, the transmission shaft 24 can transmit the driving force from the conductive end 104 to the driving end. When the counting of the counting component 5 is completed, the transmission process of the transmission shaft 24 is cut off. The cutting can be performed at any position of the transmission shaft 24, or between the transmission shaft 24 and its left gear or between the transmission shaft 24 and its right gear.

[0069] Figure 8 is a schematic diagram of partial component disassembly of a driving end of a developing cartridge according to a third embodiment of the present invention; Fig.9A is a side view of the driving end of the developing cartridge according to the third embodiment of the present invention when viewed from below to above; Fig. 9B It is a side view of the developing box involved in the third embodiment of the present invention when viewed from the left to the right.

[0070] Different from the above-mentioned embodiment, in this embodiment, the driving force received by the driving force receiving member 3 is not transmitted to the conductive end 104, but is transmitted to the counting component 5 at the driving end 103. The specific transmission method is that the belt 15 is used as a transmission member and is respectively combined with the driving force receiving member 3 or the first gear 41 and the driving gear 44.

[0071] like Figure 8As shown, the driving force receiving member 3 or the first gear 41 is provided with an active part combined with the belt 15, and the driving gear 44 includes a driven part 441 and a gear body 442 combined with each other, wherein the driven part 441 is farther away from the housing 1 than the gear body 442; Fig.9A As shown, the first forced pushing portion 14a protrudes to the left from the housing 1. Along the left-right direction, the belt 15 is farther away from the left side wall 1a1 than the first forced pushing portion 14a. The installation and operation of the belt 15 will not be restricted by the first forced pushing portion 14a.

[0072] Along the front-to-back direction, the first forced pushing portion 14a is located between the active portion and the driven portion 441. Fig. 9B As shown, the active part is coaxially arranged with the driving force receiving member 3 / the first gear 41, and the driven part 441 is coaxially arranged with the gear body 442, so the rotation center of the active part is M, the rotation center of the driven part is N, and along the line MN connecting the two rotation centers, the maximum distance between the active part and the driving gear 44 is S3. As in the first embodiment, the first forced pushing part 14a is at least located in the area defined by the maximum distance S3. Furthermore, the first forced pushing part 14a is located in the area defined by the distance S1 between the two rotation centers, and a part of the first forced pushing part 14a is opposite to the area defined by the minimum distance S2, and the area defined by the minimum distance S2 is formed as a vacant area, which is conducive to the first forced pushing part 14a adjusting its position and shape in the vacant area according to needs.

[0073] Furthermore, when viewed along the left-right direction, the first forced pushing portion 14a at least does not overlap with the gear body 442 of the driving gear 44, and a spacing area S4 is formed between the two. After counting is completed, the interruption of the driving force between the driving gear 44 and the counting component 5 can still be achieved by setting at least the gear body 442 of the driving gear 44 to be movable in the moving direction. Preferably, the driving gear 44 as a whole is set to be movable in a plane perpendicular to the left-right direction. Since the belt 15 is farther away from the housing 1 than the first forced pushing portion 14a, when the driving gear 44 as a whole moves, the driven portion 441 will not interfere with the first forced pushing portion 14a. Fig. 9B As shown, in this embodiment, the driven body 52 is configured as a toothless gear having a tooth portion 521 and a toothless portion 522 to achieve the interruption of the transmission of the driving force between the driving gear 44 and the counting assembly 5 .

[0075] Fig.10 is a side view of the developing cartridge according to the fourth embodiment of the present invention when viewed from the left to the right; Fig.11 It is a side view of the driving end of the developing box involved in the fourth embodiment of the present invention when viewed from the bottom to the top.

[0076] The present embodiment is an alternative implementation of the third embodiment, and the difference lies in that, in the present embodiment, the active part and the third gear / powder delivery gear 43 are coaxially arranged, and a vacant area still needs to be formed between the active part and the driven part 441, and the driving force is transmitted between the two through the belt 15; the plane where the movement direction of the belt 15 is located and the rotation axis of the active part can be perpendicular to each other, or can be at an angle, as long as the belt 15 can transmit the driving force from the active part to the driven part 441, from the perspective of labor saving and stability of driving force transmission, preferably, the plane where the movement direction of the belt 15 is located is perpendicular to the rotation axis of the active part.

[0077] like Fig.11 As shown, along the left-right direction, the belt 15 is farther away from the left side wall 1a1 than the first forced pushing portion 14a, so that the installation and operation of the belt 15 will not interfere with the first forced pushing portion 14a; Fig.10 As shown, the rotation center of the active part is P, the driven part 441 is still coaxially arranged with the driving gear 44, and its rotation center is N. Along the line PN connecting the two rotation centers, the maximum distance between the active part and the driven part 441 is S3, the minimum distance is S2, and the distance between the two rotation centers is S1. The first forced pushing part 14a is located in the area defined by the maximum distance S3, further, the first forced pushing part 14a is located in the area defined by the distance S1, and further, the first forced pushing part 14a is entirely located in the area defined by the minimum distance S2, that is, the first forced pushing part 14a is entirely located in the vacant area; at the same time, when viewed along the left and right directions, the first forced pushing part 14a at least does not overlap with the gear body 442 of the driving gear 44, and a spacing area S4 is formed between the two. Compared with the above embodiment, the driving gear 44 / gear body 441 in this embodiment has a larger movable space, and the design freedom of the first forced pushing part 14a is also higher.

[0078] [Example 5]

[0079] Fig.12 is a three-dimensional diagram of the driving end of the developing cartridge involved in the fifth embodiment of the present invention after the driving end cover is hidden; Fig.13 It is a side view of the developing box involved in the fifth embodiment of the present invention when viewed from left to right along the left and right direction thereof.

[0080] In this embodiment, the driving force transmission between the driving force receiving member 3 / first gear 41 / third gear 43 directly serving as the active part or provided with the active part and the driving gear 44 serving as the driven part is replaced by the gear rod 16, that is, in this embodiment, the transmission member is the gear rod 16. As shown in the figure, the gear rod 16 includes a rod body 163 and a first combination portion 161 and a second combination portion 162 respectively located at both ends of the rod body 163, the first combination portion 161 is used to combine with the active part, the second combination portion 162 is combined with the driving gear 44, and the rod body 163 does not contact the first forced pushing portion 14a; similarly, the rotation axis of the gear rod 16 and the rotation axis of the active part can be perpendicular to each other, or can be in an angle shape, as long as the gear rod 16 can transmit the driving force from the active part to the driven part. Preferably, the rotation axis of the gear rod 16 / rod body 163 is perpendicular to the rotation axis of the active part. In the following, the combination of the first combination portion 161 and the first gear 41 is described as an example.

[0081] Preferably, the first coupling portion 161 and the second coupling portion 162 are both provided with a plurality of teeth along the rotation direction thereof, and the driving gear 44 comprises a positioning portion 443 and a gear body 441 coupled to each other, wherein the positioning portion 443 is used to position the driving gear 44 relative to the driving end cover 11. The gear body 441 is coupled to the second coupling portion 162 and the counting assembly 5 at the same time. Fig.13 As shown, the distance between the rotation center M of the driving force receiving member 3 and the rotation center N of the gear body 441 is S1, and along the line direction of the two rotation centers MN, the minimum distance between the first gear 41 and the gear body 441 is S2, and a vacant area is formed between the two, and the first forced push portion 14a is entirely located in the vacant area. In the gear body 16, at least the rod body 161 is located in the vacant area. When viewed from the left and right directions, the first forced push portion 14a is separated from the gear rod, and at the same time, a spacing area S4 is also formed between the first forced push portion 14a and the gear body 441. Similar to the fourth embodiment, the driving gear 44 / gear body 441 in this embodiment has a larger movable space, and the design freedom of the first forced push portion 14a is also higher. Alternatively, the first coupling portion 161 of the gear rod can also be combined with the powder feeding gear / third gear 43, and the rotation axis of the powder feeding gear / third gear 43 is parallel to the rotation axis of the driving force receiving member.

[0082] [Example 6]

[0083] Fig.14 is a side view of the driving end of the developing cartridge according to the sixth embodiment of the present invention when viewed from above to below; Fig.15 It is a side view of the driving end of the developing box involved in Example 6 of the present invention when viewed from below to above.

[0084] Different from the fifth embodiment, the driving gear 44 in this embodiment is no longer provided with the positioning portion 443, and thus, the driving gear 44 in this embodiment is the gear body 441 in the fifth embodiment, and the second coupling portion 162 of the gear rod 16 is coupled to the driving gear 44. Similar to the fifth embodiment, a vacant area is still formed between the first gear 41 and the driving gear 44, and the first forced pushing portion 14a is entirely located in the vacant area. Meanwhile, a spacing area S4 is also formed between the first forced pushing portion 14a and the driving gear 44, and thus, the driving gear 44 has a larger movable space, and the design freedom of the first forced pushing portion 14a is also higher.

[0085] Furthermore, since the positioning portion 443 is eliminated, the size of the driving gear 44 can be reduced in the left-right direction, and accordingly, the size of the developing box C at the position corresponding to the driving gear 44 and the gear rod 16 can be reduced.

[0086] The area defined by the above-mentioned minimum distance S2, the area defined by the distance S1 and the area defined by the maximum distance S3 refer to the area corresponding to the distances S1 / S2 / S3 in the direction perpendicular to the straight line MN / PN in space. Therefore, the vacant area can be understood as the area corresponding to the minimum distance S2 in the direction perpendicular to the straight line MN / PN in space, and a part of the transmission member 15 / 16 is located in the vacant area; the spacing area can be understood as the area between the part where the driving gear 44 and the first pushing portion 14a overlap / are of equal size when observed in the up and down direction and the first pushing portion 14a.

[0087] [Example 7]

[0088] Fig.16A and Fig. 16B is a three-dimensional diagram of a counting part in a counting assembly according to a seventh embodiment of the present invention; Fig.17A is a top view of the counting part of the counting assembly involved in the seventh embodiment of the present invention when observed along its rotation axis; Fig. 17B This is a bottom view of the counting part of the counting component involved in Example 7 of the present invention when observed along its rotation axis.

[0089] As described above, the process of transmitting the driving force from the driving force receiving member 3 to the driving gear 44 is no longer achieved through the gears arranged between the driving force receiving member 3 and the driving gear 44. Therefore, compared with the method of using the gear transmission, the driving gear 44 in the present invention may be inconsistent with the predetermined rotation speed, or the rotation speed of the driving gear 44 may be faster or slower than the predetermined rotation speed, and then the counting component 5 may also be faster or slower than the predetermined rotation speed, so that the counting component 5 cannot realize the counting function; or, the diameter of the counting component 5 is reduced to reduce its manufacturing cost, at this time, the rotation speed of the counting component 5 will also become faster.

[0090] To this end, the present invention further provides a speed adjustment component located between the driving gear 44 and the counting component 5, which is used to adjust the rotation speed of the counting component 5 when it is driven by the driving gear 44 according to the counting requirements of the counting component 5, so that the counting component 5 can finally achieve its counting function. When the rotation speed of the driving gear 44 is slower than the predetermined rotation speed, at this time, it is necessary to speed up the rotation speed of the counting component 5, which can be achieved by simple methods such as increasing the diameter of the driving gear 44 and reducing the diameter of the driven body 52.

[0091] In this embodiment, the case where the rotation speed of the driving gear 44 is faster than the predetermined rotation speed is used as an example for description. At this time, the speed regulating component is actually a delay device. Without changing the rotation speed of the driving gear 44, the average speed of the counting component 5 during the counting process is reduced, so that during the counting process of the counting component 5, the time required for the counting member 51 to rotate by a predetermined angle is prolonged.

[0092] like Fig.16A and Fig. 16B As shown, in this embodiment, the counting part of the counting component 5 includes a counting member 51 and a driven member 52 which are combined with each other. Similarly, the counting member 51 and the driven member 52 can be formed in one piece or in separate pieces. The driven member 52 is used to receive the driving force of the driven part, thereby driving the counting member 51 to rotate around the rotation axis L5 in the direction shown by r1, and interact with the detection component in the imaging device; in this embodiment, the counting member 51 is directly or indirectly arranged on the left side surface 52a of the driven body 52.

[0093] The counting member 51 includes a cylinder 510 connected to the driven body 52 and at least one counting protrusion extending radially outward along the cylinder 510. During the counting process of the counting component 5, the counting protrusion moves or presses the detection component in the imaging device. In this embodiment, the counting member 51 is provided with a first counting protrusion 511 and a second counting protrusion 512 arranged at intervals along the rotation direction r1; it can be understood that the cylinder 510 can be omitted, and the first counting protrusion 511 and the second counting protrusion 512 are directly combined with the driven body 52 and rotate with the rotation of the driven body 52.

[0094] The counting part further includes a triggered member 55 for driving the driven body 52 to rotate. When the driven body 52 is in a state of stopping rotation, the triggered member 55 is actuated by an external trigger member 445 (such as Fig.18The driven body 52 is driven to continue rotating after being triggered (as shown). Preferably, the triggered member 55 is a force-bearing protrusion combined with at least one of the driven body 55 and the support body 53. More preferably, the triggered member 55 is combined with the driven body 55 and the support body 53 at the same time, and the triggered member 55 is formed to protrude radially outward from the circumferential surface of the support body 53, but the triggered member 55 does not protrude beyond the driven body 52, so as to prevent the triggered member 55 from causing unnecessary interference. When the counting part is configured to rotate around a rotation axis, the counting part further includes a sleeve 54 combined with the driven body 52, and the sleeve 54 extends from the right side surface 52b of the driven body 52 along the rotation axis L5.

[0095] The driven body 52 is configured as a rotating body that can rotate around the rotation axis L5, and the driving part 521 and the non-driving part 522 are arranged along the circumferential direction of the rotating body, wherein the driving part 521 is used to receive an external driving force to make the rotating body 52 rotate, and the non-driving part 522 is used to cut off the driving force transmitted to the rotating body 52 so that the rotating body 52 no longer rotates. In this embodiment, the driving part 521 is configured as a toothed part arranged along the circumferential direction of the rotating body, and the non-driving part 522 is configured as a toothless part arranged along the circumferential direction of the rotating body.

[0096] When the counting component 5 and the driving gear 44 are disengaged by the first method described in Example 1, the driving part 521 at least includes a first driving part 521a and a second driving part 521b arranged at intervals along the rotation direction of the rotating body, and the non-driving part 522 at least includes a first non-driving part 522a and a second non-driving part 522b arranged at intervals along the rotation direction of the rotating body. When the counting component 5 is in the counting state, the first driving part 521a, the second driving part 521b and the second non-driving part 522b are opposite to the driving gear 44; when the counting component 5 completes counting, the first non-driving part 522a is opposite to the driving gear 44.

[0097] like Fig.17A and Fig. 17BAs shown, along the rotation direction r1 of the rotating body, the first driving part 521a, the second non-driving part 522b, the second driving part 521b and the first non-driving part 522a are arranged adjacent to each other in sequence. During the counting process of the counting component 5, when the second driving part 521b is opposite to the driving gear 44, the rotating body 52 receives the driving force to rotate. As the second non-driving part 522b is opposite to the driving gear 44, the rotating body 52 no longer receives the driving force and stops rotating. Therefore, the second non-driving part 522b can be regarded as an embodiment of the cutting part, which is used to temporarily cut off the driving gear 44 from the rotating body. 52; when the trigger member 55 is triggered by an external component, the rotating body 52 starts to rotate again until the first driving portion 521a is opposite to the driving gear 44, and then the rotating body 52 continues to rotate. When the first non-driving portion 522a is opposite to the driving gear 44, the counting component 5 completes the counting and the rotating body 52 remains stationary. The first non-driving portion 522a can be regarded as a formal embodiment, which is used to completely cut off the driving force transmission between the driving gear 44 and the rotating body 52. ​​Regardless of whether the driving gear 44 continues to rotate, the rotating body 52 remains stationary.

[0098] Regarding the position of the triggered member 55, based on the inventive concept of the present invention, when the trigger member 445 triggers the triggered member 55, the triggered member 55 can drive the rotating body 52 to start rotating again; as a preferred method, when observed along the rotation axis L5, the triggered member 55 is opposite to the second non-driving portion 522b, and more preferably, along the rotation direction r1, the triggered member 55 is roughly located in the middle position of the arc corresponding to the second non-driving portion 522b, which can ensure that when the triggered member 55 is triggered, the first driving portion 521a and the driving gear 44 can engage smoothly.

[0099] Fig.18 It is a stereoscopic diagram of the stirring member gear involved in the seventh embodiment of the present invention.

[0100] The driving gear 44 includes a main body 440, teeth 441 arranged along the circumferential direction of the main body, a D-shaped portion 444 located in the main body 440, and a trigger member 445 extending radially outward along the circumferential surface of the main body. The agitator 23 or the transmission shaft 24 is combined with the D-shaped portion 444, so that the driving gear 44 can obtain the driving force transmitted by the agitator 23 or the transmission shaft 24; the trigger member 445 is configured to be an extended protrusion that can push the triggered member 55.

[0101] Figures 19A-19F It is a schematic diagram of the counting process of the counting part in the counting component involved in the seventh embodiment of the present invention.

[0102] Before describing the working process of the counting component, first combine Fig.16A and Fig.17AThe structure of the second counting protrusion 512 involved in this embodiment is described. As shown in the figure, along the rotation direction r1, the first counting protrusion 511 and the second counting protrusion 512 are arranged at intervals, and the second counting protrusion 512 is formed as a fan-shaped extension body, having an upper side plate 5121 located upstream, a lower side plate 5122 located downstream, and an arc plate 5123 located between the upper side plate and the lower side plate, and the arc plate 5123 has a front end point 512a located at the upstream end and a rear end point 512b located at the downstream end, and the radial outer side of the arc plate 5123 forms an arc surface 512c with an arc length of m.

[0103] Combine the following Figures 19A-19F The counting process of the counting assembly 5 is described. In order to more clearly describe the working process of the counting part, only the driving gear 44 and the counting part are shown in the figure.

[0104] When the developing box C is installed in the imaging device but has not started working, the counting protrusion and the detection component 9 in the imaging device may or may not be in contact with each other. Regardless of the relative positions of the two, the speed adjustment component of the present invention is applicable. Fig.19A In the figure, before the developing box C starts working, the first counting protrusion 511 and the detecting component 9 abut against each other, and the tooth 441 of the driving gear 44 engages with the second driving part 521b. When the driving force of the driving force receiving member 3 causes the driving gear 44 to start rotating in the direction indicated by r2, the rotating body 52 is driven to rotate in the direction indicated by r1, and the detecting component 9 and the first counting protrusion 511 continue to interact with each other.

[0105] like Fig.19B As shown, when the first counting protrusion 511 moves to disengage from the detection component 9, the detection component 9 begins to abut against the front end 512a of the second counting protrusion 512, and the driving gear 44 is opposite to the second non-driving portion / cut-off portion 522b. At this time, the rotating body 52 remains stationary, and accordingly, the second counting protrusion 512 is always in abutment with the detection component 9. In the process of the driving gear 44 and the second driving portion 521b being engaged, the triggering member 445 and the triggered member 55 both move toward the area where the driving gear 44 and the rotating body 52 are opposite, but the triggering member 445 arrives at the area before the triggered member 55, so that the triggered member 55 does not interfere with the triggering member 445.

[0106] As the driving gear 44 continues to rotate in the direction indicated by r2, Fig.19C As shown, along the rotation direction r1, the triggering member 445 reaches the upstream of the triggered member 55, and then the triggered member 55 is triggered, and the rotating body 52 starts to rotate along the direction shown by r1 again, as shown in FIG. Fig.19D and Fig.19EAs shown, the driving gear 44 begins to mesh with the first driving portion 521a, and the arc surface 512c abuts against the detection component 9 until the driving gear 44 is opposite to the first non-driving portion / formal 522a, as shown in FIG. Fig.19F As shown, the counting assembly 5 stops rotating after completing counting, and the driving gear 44 still rotates in the direction indicated by r2. At this time, the detection component 9 is out of contact with the rear end point 512b of the second counting protrusion 511.

[0107] When the driving gear 44 begins to face the cutting portion 522b or the driving gear 44 and the second driving portion 521b just disengage, the trigger member 445 is located at Fig.19B In the first position shown in FIG. 1 , as the driving gear 44 rotates, when the triggering member 445 reaches the point where it starts to trigger the triggered member 55, the triggering member 445 is located at Fig.19C In order to clearly describe the first position and the second position, the trigger member 445 at the first position and the trigger member 445 at the second position are both in Fig.19C As shown in the figure, the dotted indicator line indicates the trigger member 445 located at the first position, and the solid indicator line indicates the trigger member 445 located at the second position. Along the rotation direction r1, the trigger members 445 at the two positions are respectively located on both sides of the triggered member 55, and along the rotation direction r2, during the process of the trigger member 445 rotating from the first position to the second position, its rotation angle is β, β<360°, and the second counting protrusion 512 is always in contact with the detection component 9, which simulates the process of the detection component 9 always interacting with the second counting protrusion 512.

[0108] During the process of meshing of the driving gear 44 and the first driving portion 521a, the detection component 9 abuts against the arcuate surface 512c. When the driving gear 44 is about to reach a position opposite to the first non-driving portion 522a, the detection component 9 reaches the rear end point 512b of the arcuate surface 512c, and when the driving gear 44 is opposite to the first non-driving portion 522a, the detection component 9 disengages from the arcuate surface 512c. At this time, the counting is completed.

[0109] It can be seen from this that in this embodiment, the time duration of the contact between the detection component 9 and the second counting protrusion 512 is equal to the rotation angle α of the driving body 52 (e.g. Fig.17AThe angle α is the angle between the front end point 512a and the rear end point 512b, corresponding to the arc length of the arc plate 5123 extending in the direction shown by r1, and the angle β corresponds to the arc length corresponding to the trigger member 445 rotating from the first position to the second position. For the existing counting member, the time that the second counting protrusion 512 in this embodiment abuts against the detection member 9 is extended, and the extended time is the time required for the driving gear 44 to rotate the angle β. Therefore, the second non-driving part / cut-off part 522b can be regarded as an embodiment of the delay device, and the cut-off part 522b is used to temporarily cut off the driving force received by the rotating body 52, so that the rotating body 52 remains stationary to achieve delay; the triggered member 55 is used to be triggered by the external trigger member 445, so that the rotating body 52 obtains the driving force again and rotates, and therefore the triggered member 55 can be regarded as an embodiment of the restarting device; the process from the rotating body 52 being temporarily cut off from the driving force to obtaining the driving force again is the delay stage, and in this delay stage, the counting component 5 is still in the counting state, specifically, the detection member 9 remains in contact with the second counting protrusion 512; therefore, even if the rotation speed of the driving tooth 44 becomes faster, the purpose of ensuring that the counting component 5 realizes the counting function can be achieved without changing the structure of the second counting protrusion 512.

[0110] For the second driving part 521b, before the developing box C starts working, the tooth 441 of the driving gear is in a position engaged with the upstream end of the second driving part 521b, which is more conducive to reducing the arc length of the second driving part 521b, and when the tooth 411 is disengaged from the downstream end of the second driving part 521b, the detection component 9 has at least disengaged from the first counting protrusion 511, or has reached a position abutting against the second counting protrusion 512, that is, the arc length of the second driving part 521b must at least be sufficient to allow the first counting protrusion 511 to rotate to disengage from the detection component 9. When the second driving portion 521b is teeth, the number of teeth is at least 6. In this way, when the driving gear 44 is disengaged from the second driving portion 521b or when the driving gear 44 is opposite to the cutting portion 522b, the first counting protrusion 511 is disengaged from the detection component 9. Preferably, the number of teeth is at least 7. This can prevent the detection component 9 from being disengaged from the first counting protrusion 511 due to manufacturing errors, but the detection component 9 cannot reach the position where it is abutted by the second counting protrusion 512. In other words, the position accuracy requirement of the first counting protrusion 511 and the second counting protrusion 512 is reduced.

[0111] Based on the technical concept of this embodiment, the delay device is arranged on the rotating body 52 to slow down the rotation speed of the counting component 5 / rotating body 52 / counting protrusion 511 / 512, thereby ensuring that the counting function of the counting component 5 is realized.

[0112] When only one trigger member 445 is provided and its relative position to the driving gear 44 remains unchanged, the position and shape of the counting protrusion can be set according to the total time and / or interval time required for the detection component 9 to be abutted during the counting process of the counting component 5. For example, when the total time for the second counting protrusion 512 in this embodiment to abut against the detection component 9 needs to be further increased / decreased, it can be achieved by extending / shortening the arc length of the arc surface 512c; when the total time for the first counting protrusion 511 in this embodiment to abut against the detection component 9 needs to be increased, an arc surface that can abut against the detection component 9 can be provided on the first counting protrusion 511, and accordingly, the number of teeth of the second driving portion 521b needs to be increased, or it can be achieved by shortening the arc length of the second driving portion 521b. At this time, the cutting portion 521b is cut off. 522b is already opposite to the driving gear 44, but the first counting protrusion 511 is still in contact with the detection component 9. A cut-off portion may be further provided upstream of the second driving portion 521b so that the driving gear 44 is equivalent to idling until the triggering member 445 triggers the triggered member 55. Furthermore, if the total duration of contact between the second counting protrusion 512 and the detection component 9 does not need to be changed, there is no need to provide a cut-off portion between the first driving portion 521a and the second driving portion 521b. The first driving portion 521a and the second driving portion 521b are connected as one, and the driving gear 44 is combined with the first driving portion 521a and the second driving portion 521b until the counting is completed. At this time, only one driving portion and one cut-off portion are provided on the circumference of the rotating body 52.

[0113] When the shape of the counting protrusion 511 / 512 does not change, but the duration of the abutment between the counting protrusion and the detection component 9 needs to be reduced, one or more trigger members can be additionally provided on the driving gear 44. When the driving gear 44 rotates, the additionally provided trigger member will trigger the triggered member 55 earlier than the trigger member 445 in this embodiment, so that the rotating body 52 can be converted earlier from the state of temporarily cutting off the driving force to the state of receiving the driving force again, and the total duration of the abutment between the second counting protrusion 512 and the detection component 9 is reduced.

[0114] For the counting member 51 having multiple counting protrusions, if it is necessary to control the interval time between two adjacent counting protrusions and the abutment with the detection component 9 to be longer, it can be achieved by reducing the arc length of the second driving portion 521b. At this time, the time duration for the second driving portion 521b to receive the driving force from the driving gear 44 becomes shorter. That is to say, the arc length of the second driving portion 521b only needs to ensure that the previous counting protrusion rotates to disengage from the abutment with the detection component 9, without having to make the next counting protrusion reach the position of abutting with the detection component 9.

[0115] [Embodiment 8]

[0116] Fig. 20It is a three-dimensional diagram of the counting part of the counting component involved in the eighth embodiment of the present invention.

[0117] Based on the seventh embodiment, this embodiment will further describe a counting part provided with multiple cutting parts, that is, the delay device in this embodiment includes multiple cutting parts. Fig. 20 As shown, the structure of the counting member 51 in this embodiment is not changed, but two cutting parts are provided on the rotating body 52, so that the total counting time of the counting member 51 is longer. Therefore, this embodiment can also be considered as another implementation method of extending the total contact time of the second counting protrusion 512 and the detection component 9 in Example 7.

[0118] Along the rotation direction r1, the rotating body 52 includes a first driving part 521a, a second driving part 521b, a third driving part 521c, a first non-driving part 522a, a second non-driving part 522b and a third non-driving part 522c. When the counting component 5 is in the counting state, the driving gear 44 is opposite to at least one of the first driving part 521a, the second driving part 521b, the third driving part 521c, the second non-driving part 522b and the third non-driving part 522c. When the counting component 5 completes counting, the driving gear 44 is opposite to the first non-driving part 522a. Therefore, the first driving part 521a, the second driving part 521b, the third driving part 521c, the second non-driving part 522b and the third non-driving part 522c. The area where the first non-driving part 521a, the second driving part 521b, the third driving part 521c, the second non-driving part 522b and the third non-driving part 522c are located can be called the counting area of ​​the rotating body 52, and the area where the first non-driving part 522a is located can be called the non-counting area of ​​the rotating body 52; similarly, for Example 7, the area where the first driving part 521a, the second driving part 521b, and the second non-driving part 522b are located can be called the counting area, and the area where the first non-driving part 522a is located can be called the non-counting area, and along the rotation direction of the rotating body 52, the counting area and the non-counting area are adjacently arranged on the circumference of the rotating body.

[0119] It should be noted that the counting area and non-counting area here are divided according to whether the counting component 5 is in the counting state, rather than according to the shape or arc length of the various driving parts and non-driving parts. That is to say, even if the arc length of the first driving part 521a is set so that the counting component 5 has completed the counting, but the driving gear 44 is still relative to / engaged with the first driving part 521a, then the part of the first driving part 521a that has not yet been relative to / engaged with the driving gear 44 should still be regarded as a part of the first non-driving part 522a.

[0120] In the counting area, along the rotation direction r1, the second driving part 521b, the second non-driving part 522b, the third driving part 521c, the third non-driving part 522c and the first driving part 521a are arranged in sequence from upstream to downstream, and when the driving gear 44 is relative to / engaged with the second driving part 521b, the third driving part 521c and the first driving part 521a, the rotating body 52 can receive the driving force and rotate, and when the driving gear 44 is relative to / engaged with the second non-driving part 522b and the third non-driving part 522c, the rotating body 52 cannot receive the driving force and remains stationary. Therefore, the second non-driving part 522b and the third non-driving part 522c can be regarded as the first cutting part and the second cutting part, respectively.

[0121] like Fig. 20 As shown, the restarting device in this embodiment includes a first trigger member 55 and a second trigger member 56 which are respectively opposite to the first cutting portion 522b and the second cutting portion 522c, wherein the first trigger member 55 is used to rotate the rotating body 52 again until the driving gear 44 is opposite to / engaged with the third driving portion 521c after being triggered, and the second trigger member 55 is used to rotate the rotating body 52 again until the driving gear 44 is opposite to / engaged with the first driving portion 521a after being triggered, and along the rotation direction r1, the third driving portion 521c is located between the first trigger member 55 and the second trigger member 56.

[0122] As described above, the counting area in this embodiment is provided with a plurality of cut-off portions, so that during the counting process of the counting component 5, the total duration of the contact / non-contact between the counting protrusion and the detection component 9 is prolonged, and the counting function of the counting component 5 can be smoothly realized.

[0123] [Example 9]

[0124] Fig.21 It is a three-dimensional diagram of the counting part of the counting component involved in the ninth embodiment of the present invention.

[0125] This embodiment is further evolved on the basis of the eighth embodiment. The counting member 51 in this embodiment is still provided with the first counting protrusion 511 and the second counting protrusion 512 separated from each other along the rotation direction r1. Compared with the seventh embodiment, the second counting protrusion 512 is configured to have the same shape as the first counting protrusion 511, and is no longer an arc-shaped plate extending along the rotation direction r1. In this embodiment, for the two counting protrusions, the counting time of the first counting protrusion 511 is the same as the counting time of the second counting protrusion 512, but the delay device located in the counting area will make the counting component 5 in the counting process. The interval time of the abutment between the first counting protrusion 511 and the second counting protrusion 512 and the detection component 9 is lengthened. Therefore, this embodiment can be regarded as another implementation method for lengthening the interval time of the abutment between two adjacent counting protrusions and the detection component 9 in the seventh embodiment.

[0126] [Example 10]

[0127] Fig. 22 It is a top view of the counting component and the driving component involved in the tenth embodiment of the present invention when combined.

[0128] In this embodiment, the reduction in diameter of the counting component 5 is described as an example. At this time, the diameters of the rotating body 52 and the counting member 51 are both reduced, and their rotation speeds are accelerated. In order to enable the counting component 5 after the diameter reduction to be used in the developing box suitable for the counting component before the diameter reduction, the counting component 5 also needs to be provided with the above-mentioned delay device.

[0129] like Fig. 22 As shown, the first driving part 521a, the second non-driving part 522b / delay device / cut-off part, the second driving part 521b and the first non-driving part 522a are arranged in sequence on the circumference of the rotating body 52 along the rotation direction r1 of the rotating body 52, and the second non-driving part 522b is located between the first driving part 521a and the second driving part 521b. Since the rotation speed of the rotating body 52 is accelerated, when the second driving part 521b is set as teeth, the number of teeth can be reduced to not less than 2, that is, when the number of teeth of the second driving part 521b is 2, as the rotating body 52 rotates from a position opposite to the upstream of the second driving part 521b to a position opposite to the downstream of the second driving part 521b, the first counting protrusion 511 can be disengaged from the detection component 5; due to the setting of the cutting part 522b, the counting time of the counting component 5 is lengthened.

[0130] It can be seen that the minimum number of teeth of the second driving part 521 b can vary within the range of 2-6, and the specific number can vary according to the diameter of the rotating body 52 .

[0131] When the counting component 5 described in the above-mentioned embodiments 7 to 9 completes counting, the rotating body 52 no longer receives the driving force by the first non-driving portion 522a disposed therein being relative to / engaged with the driving gear 44, that is, the first disengagement method recorded in the first embodiment. For embodiments 7 to 9, the arc length of the first non-driving portion 522a is not less than the circumference of the trigger member 445 when it rotates with the driving gear 44. Therefore, when the driving gear 44 is relative to / engaged with the first non-driving portion 522a, even if the driving gear 44 continues to rotate, the trigger member 445 will not trigger the triggered member 55 to cause the rotating body 52 to continue rotating.

[0132] However, when the counting component 5 completes counting, the rotating body 52 and the driving gear 44 adopt the second or third disengagement method described in Example 1, and the specific structure of the first non-driving portion 522a will no longer be important. At this time, the first non-driving portion 522a can be set to a toothless portion as described above, or it can be set to a toothed portion. But no matter what the specific structure of the first non-driving portion 522a is, when the counting component 5 completes counting, the counting piece 51 and the rotating body 52 are disengaged, even if the rotating body 52 is still driven to rotate by the driving gear 44, the counting piece 51 will remain stationary, or, at least one of the rotating body 52 and the driving gear 44 moves in a direction intersecting the left and right directions. At this time, the rotation center of the driving gear 44 and the rotation center of the rotating body 52 are far away from each other. Even if the driving gear 44 continues to rotate, the rotating body 52 cannot receive the driving force and remains stationary.

[0133] [Beneficial Effects]

[0134] As described above, when the driving force transmission method described in Example 1 and Example 2 is adopted, the driving force received by the driving force receiving member 3 from the imaging device is first transmitted from the driving end 103 to the conductive end 104, and then transmitted from the conductive end 104 to the driving end 103. Although a gear for transmitting the driving force is also required to be provided at the conductive end 104, the gear density on the side where the driving end 103 is located is effectively reduced. Regardless of whether the developing box C is assembled manually or by machine, gears can be installed on both sides at the same time. Compared with the existing developing box, the gear density on the side where the driving end is located is larger, and there is overlap between the gears in the left and right directions. The above-mentioned method of installing gears on both sides of the developing box at the same time will actually improve the assembly efficiency.

[0135] The counting assembly 5 needs to be driven when counting, but does not need to be driven when counting is completed. When the driving force is transmitted from the conductive end 104 to the driving end 103 by the transmission shaft 24 parallel to the stirring frame 23, that is, the driving force required by the counting assembly 5 no longer comes from the stirring member 23, and the load of the stirring member 23 during rotation will not suddenly decrease, so the working stability of the stirring member 23 is guaranteed. On the other hand, when the counting assembly 5 completes counting, the driving force transmission of the transmission shaft 24 can be set to be interrupted, and the interruption of the driving force transmission will not affect the operation of the stirring member 23, and there are many options for the interruption position, for example, the interruption position can be at the conductive end 104, the driving end 103, or the body of the transmission shaft 24.

[0136] In the embodiment of the present invention, a missing area is formed between the driving force receiving member 3 / first gear 41 / third gear 43 which directly serves as the active part or is provided with the active part and the driving gear 44 which directly serves as the driven part or is provided with the driven part. Along the front-to-back direction, the active part is located in front of the driven part, and the driving force is transmitted between the two in a non-gear combination manner. The position of the counting component 5 can be adjusted in the missing area as needed, or the radial size of the driven body 52 can be adjusted as needed. Correspondingly, the position of the driving gear 44 can also be adjusted in the missing area, so that the developing box C can be compatible with a variety of models.

[0137] The vacant area provides sufficient space for the movement of the driving gear 44. As mentioned above, the interruption of the driving force transmission between the driving gear 44 and the counting component 5 is preferably such that at least one of the driving gear 44 and the driven body 52 moves in the moving direction. Since the driven body 52 is a part of the counting component 5, and the counting component 5 also needs to interact with the detection component in the imaging device, the driving gear 44 is moved in the moving direction in a better way. The existence of the vacant area can give the control device for controlling the movement of the driving gear 44 a higher degree of design freedom.

[0138] As described above, at least a portion of the first pushing portion 14a is located in the vacant area, which not only allows the first pushing portion 14a to be adjusted in position in the developer box C according to the position of the external pushing force applying component, but also allows a stronger reinforcement portion to be provided for the first pushing portion 14a; for example, when two models of developer boxes only have slightly different positions of the first pushing portion 14a, the existence of the vacant area can make the developer box universal; for example, when the pushing force applied by the pushing force applying component applicable to a certain model of developer box is large, the designer can make full use of the vacant area to design a reinforcement portion for the first pushing portion 14a; on the contrary, when the pushing force applied by the pushing force applying component is small, the designer can also make full use of the vacant area to design a dispersion portion for the first pushing portion 14a that can disperse the pushing force.

[0139] The vacant area also simplifies the structure of the driving gear 44. No matter whether it is coaxially arranged with the stirring member 23, the driving gear 44 only needs to be arranged at one level. In particular, in the above-mentioned embodiments 1 and 2, as described above, the sizes of the driving gear 44 and the counting assembly 5 can be reduced along the left and right directions. Therefore, the sizes of the corresponding positions of the developing box C and the driving gear 44 and the counting assembly 5 can also be reduced accordingly.

[0140] For the embodiment in which the driving force is transmitted from the active part to the driven part by the belt 15 or the gear rod 16, similarly, a vacant area is still formed between the driving force receiving member 3 / the first gear 41 / the third gear 43 as the active part and the driving gear 44 as the driven part. On the one hand, the conductive end 104 does not need to be provided with a gear for transmitting the driving force. On the other hand, the existence of the vacant area can also make the counting component 5 universal, provide space for the movement of the driving gear 44, and make the first forced pushing part 14a have a higher degree of freedom in design.

[0141] When the rotation speed of the driving gear 44 is faster or slower than the expected rotation speed, by setting a speed adjustment component in the developing box, the counting component 5 can smoothly complete the counting process without changing the structure of the driving gear 44 or the counting member 51. At the same time, the structure of the speed adjustment component can be adjusted according to the counting requirements of the counting member 51 in the target developing box, so that the same counting member 51 can be used for multiple models.

[0142] For the developing box in which the speed adjustment component is set as a delay device, the delay device is directly set on the rotating body 52, and there is no need to reserve space in the developing box C for setting the delay device. The overall structure of the developing box C is simplified, and the delay device can also be formed integrally with the rotating body 52, so that the delay device can be installed along with the installation of the rotating body 52, and the installation steps of the developing box will not be increased.

[0143] Specifically, the delay device in the present invention achieves delay by disengaging the rotating body 52 from the driving member 44 so that the rotating body 52 stays for a predetermined time, and then the rotating body 52 is re-engaged with the driving member 44 by the re-starting device. It can be seen that during the entire counting process of the counting component 5, the average speed of the counting component 5 is reduced, and the time required for the counting member to rotate a predetermined angle is prolonged, but the rotation speed of the driving gear 44 is not changed, and the rotation speed of the rotating body 52 during rotation is also not changed. This makes it unnecessary to change the structure of the driving gear 44. The counting component 5 only needs to add a delay device that can be formed integrally with the rotating body 52, and the overall cost of the developing box C can be controlled.
