[0002] This invention relates to the field of electrophotographic imaging, and more particularly to a developing cartridge that can be detachably installed in an electrophotographic imaging device. Background Technology

[0003] A developing cartridge is a container that holds developer. When the developing cartridge is installed in an electrophotographic imaging device (hereinafter referred to as "the device"), electrostatic imaging technology is used to display the image or text desired by the user on the imaging medium. In order for the device to know information such as the model of the developing cartridge, existing developing cartridges are equipped with a detection device that can interact with the workpiece being tested in the device.

[0004] Generally, one end of a developing cartridge is used to receive driving force and is called the driving end, and the other end is used to receive electricity and is called the conductive end. In one type of developing cartridge, a detection device is located at the conductive end, which is also called the detection end. The driving force received by the driving end from the imaging device is transmitted to the detection end through a stirring element that is rotatably disposed in the developing cartridge, thereby driving the detection device.

[0005] In actual products, the detection device includes multiple components, and the drive end is also equipped with gears for transmitting driving force. This requires that when assembling the developing cartridge, both the drive end and the detection end need to be carefully considered to avoid missing any components. It is evident that this structure not only makes the detection end complex but also hinders the improvement of the assembly efficiency of the developing cartridge. Summary of the Invention

[0006] In view of this, the present invention provides a developing cartridge to simplify the structure of the detection end and improve the assembly efficiency of the developing cartridge, specifically as follows:

Detailed Implementation

[0124] It should be understood that the various embodiments described below are not isolated from each other, and those skilled in the art can combine the structures of the following embodiments according to design requirements.

[0125] Example 1

[0126] [The overall structure of the developing chamber]

[0127] like Figures 1A-25B As shown, the developing cartridge 1 includes a housing 2 forming a developer chamber 10 and a rotating member 3 rotatably mounted in the housing 2. The rotating member 3 may be, for example, a developing member 31 for conveying developer outward, a powder feeding member 32 arranged adjacent to the developing member 31 and conveying developer to the developing member 31, or a stirring member 33 located in the developer chamber 10. The stirring member 33 stirs the developer in the developer chamber 10, which on the one hand prevents the developer from clumping, and on the other hand conveys the developer toward the powder feeding member 32. The developing cartridge also includes a handle 23 connected to the housing 2. The developing member 31 and the handle 23 are located at opposite ends of the housing 2 along the installation direction.

[0128] The developing element 31 rotates about a first axis L1, and the housing 2 extends along a first direction parallel to the first axis L1. The developing cartridge 1 also has a second direction perpendicular to the first direction and a third direction perpendicular to both the first and second directions. One end 51 of the first direction points to the left of the developing cartridge, and the other end 52 of the first direction points to the right of the developing cartridge. One end 53 of the second direction points to the front of the developing cartridge, and the other end 54 of the second direction points to the rear of the developing cartridge. One end 55 of the third direction points to the top of the developing cartridge, and the other end 56 of the third direction points to the bottom of the developing cartridge.

[0129] In the following text, the left end of the developing cartridge is the driving end, and the right end is the conductive end. The device to be tested 9 is located on the right side of the developing cartridge; therefore, the right end of the developing cartridge can also be referred to as the detection end. The developing cartridge 1 also includes a detection device 6, which has a portion located at the driving end, another portion located at the detection end, and a portion located between the driving end and the detection end. The driving force transmission assembly 4 is used to transmit the driving force received by the driving force receiver 41 located at the driving end to the rotating member 3 and the detection device 6.

[0130] The housing 2 has a left surface 21 facing left, a right surface 22 facing right, and a left end cover 27 and a right end cover 28 respectively coupled to the housing 2. The left end cover 27 faces the left surface 21, and the right end cover 28 faces the right surface 22. A portion of the driving force receiving member 41 is exposed outward from the left end cover for receiving driving force from the imaging device. A portion of the detection device 6 is exposed outward from the right end cover 28. Figure 1BAs shown, the right end cover 28 has an exposure port 281, the size of which is larger than the size of the component (hereinafter referred to as the functional component 63) of the detection device 6 located at the detection end; furthermore, the developing cartridge 1 also includes a developer adjusting member 29 fixedly installed on the housing 2, a conductive member 26 combined with the housing 2, and a chip assembly 11 installed on one of the housing 2, the left end cover 27, and the right end cover 28. The chip assembly 11 can be a chip that is simultaneously provided with a substrate, electrical contacts, and a storage part, or it can be a movable member that has a substrate, electrical contacts, a storage part, and can be movably connected to the electrical contacts. The conductive member 26 is located at the detection end and is used to receive power from the device to supply at least to the developing member 31. The number of electrical contacts is set to be multiple.

[0131] When the developing cartridge 1 is working, the developing element 31 needs to be aligned with the photosensitive element outside the developing cartridge so that the developer on the surface of the developing element 31 can reach the surface of the photosensitive element to achieve development. Therefore, it is advantageous for the developing cartridge 1 to be pushed towards the photosensitive element. Figure 1C and Figure 2 As shown, the developing cartridge 1 also includes a first forced push portion 2b1 and a second forced push portion 2b2 disposed at the rear of the developing cartridge. The first forced push portion 2b1 is located on the left side of the housing 2, and the second forced push portion 2b2 is located on the right side of the housing 2. Specifically, the first forced push portion 2b1 protrudes to the left from the left side of the housing 2, and the second forced push portion 2b2 protrudes to the left from the right end cover 28. That is to say, along the first direction, the first forced push portion 2b1 and the second forced push portion 2b2 both protrude in the same direction. Therefore, the first forced push portion 2b1 and the second forced push portion 2b2 can also both protrude to the right. This structure is beneficial to the miniaturization of the developing cartridge 1.

[0132] The developing element 31 includes a developing shaft and a developing layer covering the surface of the developing shaft. Along the first direction, the length of the developing layer is less than the length of the developing shaft. Part or all of the length of the developing layer forms a developing area, and the developing layer has two opposite end faces in the first direction, namely, the end face of the developing layer at the driving end and the end face of the developing layer at the detection end are arranged opposite each other. The plane passes through the end face of the developing layer at the detection end. When viewed along the third direction, multiple electrical contacts are located to the right of the plane, or in other words, multiple electrical contacts and the developing layer are located on opposite sides of the plane. Along the first direction, multiple electrical contacts are set away from the developing element 31 / developing layer. In this way, in the second direction, multiple electrical contacts do not overlap with the developing layer, and the developer spilled on the surface of the developing layer will not directly reach multiple electrical contacts. Therefore, the risk of short circuit of the multiple electrical contacts or the chip is reduced.

[0133] Generally, imaging equipment includes a first power output device for supplying power to the powder feeder 32 and a second power output device for supplying power to the developing unit 31. The voltage output by the first power output device is higher than that output by the second power output device. The conductive element 26 can be configured to receive power from at least one of the first and second power output devices. For example, the conductive element 26 receives power only from the first power output device and supplies the received power to both the developing unit 31 and the powder feeder 32 simultaneously. In this way, the voltage required by both the developing unit 31 and the powder feeder 32 can be satisfied during the operation of the developing unit. Alternatively, the conductive element 26 receives power only from either the first or second power output device and supplies the received power first to the developer conditioning element 29, then the developer conditioning element 29 supplies power to the surface of the developing unit 31, and finally the developing unit 31 supplies power to the surface of the powder feeder 32 that is in contact with the surface of the developing unit.

[0134] [Right end cap]

[0135] Along the second direction, the right end cover 28 is located behind the conductive element 26. A portion 282 of the right end cover 28 is formed as a second forced push portion 2b2. A portion of the active component is exposed from the exposure port 281. When viewed along the first direction, the right end cover 28 does not coincide with the powder filling port 2a3 provided at the detection end. When the developer in the developing cartridge is consumed, the user can directly replenish the developer in the developing cartridge without disassembling the right end cover 28.

[0136] In some variations, the right end cover 28 can also be configured to cover at least a portion of the powder filling port 2a3, that is, when viewed along the first direction, the right end cover 28 and at least a portion of the powder filling port 2a3 overlap. Correspondingly, when it is necessary to add developer to the developing cartridge, the right end cover 28 needs to be removed. Although this method increases the number of operation steps, the powder filling port 2a3 can be protected by the right end cover 28 and is not easily damaged.

[0137] Along the third direction, the powder filling port 2a3 is located below the actuating component 63. For the actuating component, which is designed as a protrusion, when the user adds developer to the developing cartridge, it will not interfere with the actuating component 63. Furthermore, the actuating component 63 and the powder filling port 2a3 can be observed by the user simultaneously, significantly reducing the probability of damage to the actuating component 63. Additionally, placing the powder filling port 2a3 below the actuating component 63 also helps to reduce the size of the housing 2 in the second direction. Especially for the driving component 61 and the driving force receiving member 41, which are spaced apart along the second direction at the driving end, the driving force transmission path between them will be shortened, thus making the transmission of driving force more efficient. Along the first direction, the powder filling port 2a3 is located between the second forced push portion 2b2 / 282 and the conductive member 26.

[0138] [Guideboard]

[0139] When the developing cartridge 1 is in operation, the imaging medium (e.g., printing paper) will pass through the developing cartridge 1 from below in a second direction along a third direction. To maintain the stability of the movement path of the imaging medium, the developing cartridge 1 also includes a guide plate 2d disposed below the housing 2, such as... Figure 1C As shown, the guide plate 2d has a continuous surface that extends substantially along a first direction and a second direction. Preferably, the surface of the guide plate 2d is smooth. More preferably, along the first direction, the surface of the guide plate 2d is planar, and along the second direction, the surface of the guide plate 2d consists of a plurality of adjacent planar surfaces, with each pair of adjacent planar surfaces intersecting at a line parallel to the first direction.

[0140] In practice, to prevent developer leakage, such as Figure 1B As shown, along the first direction, the developing cartridge 1 also includes first sealing members 39 located at the two longitudinal ends of the developing member 31, and as shown in the figure. Figure 3 As shown, along the second direction, the developing cartridge also includes at least a portion of a second seal 38 and a third seal 37 located in front of the developing element 13. The first seal 39 is preferably felt / sponge for sealing the longitudinal end of the developing element 31. The second seal 38 is preferably a sheet seal for contacting and sealing the circumferential surface of the developing element 31. The third seal 37 is preferably a sponge for contacting and sealing the circumferential surface of the developing element 31.

[0141] In the existing method, the first seal 39, the second seal 38 and the third seal 37 are all attached to the housing 2 by attaching double-sided tape to one side. On the one hand, this method is not conducive to automated production, and the first seal 37 located at the two longitudinal ends of the developing piece will be subjected to a large tensile force, causing the first seal to be torn open. On the other hand, this method has low installation accuracy, resulting in poor sealing effect.

[0142] This invention achieves precise bonding between the first seal 39 / second seal 38 and the housing 2 by injecting adhesive on the side of the first seal 39 / second seal 38 facing the housing. For example... Figure 1CAs shown, two injection ports 2e are also provided below the housing 2. Each injection port 2e is connected to at least one of the first seal 39 and the second seal 38. In this way, the adhesive injected through the injection port 2e can smoothly reach the side of the first seal 39 and / or the second seal 38 facing the housing 2. Injecting adhesive through the injection port 2e not only increases the bonding strength between the seal and the housing 2, but also effectively fills the gaps between the first seal 39, the second seal 38, and the third seal 37, as well as the gaps between the seals and the housing 2. In addition, injecting adhesive through the injection port 2e can also enable automated production of the developing cartridge 1. Preferably, along the first direction, the guide plate 2e is located between the two injection ports 2e to avoid the guide plate 2d from blocking the injection ports 2e. Further, along the first direction, the guide plate 2e is located between the conductive element 26 and the chip assembly 11 to avoid the chip assembly 11 being affected by the conductive element 26.

[0143] [Drive force transmission components]

[0144] The driving force transmission assembly 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43, and a stirring member driving member 44. The developing member driving member 42 is used to drive the developing member 31 to rotate, the powder feeding member driving member 43 is used to drive the powder feeding member 32 to rotate, and the stirring member driving member 44 is used to drive the stirring member 33 to rotate. When a stirring component driver 44 is provided, the driving force transmission assembly 4 also includes an idler wheel 45 located between the driving force receiver 41 and the detection device 6. The driving force receiver 41 transmits the driving force to the stirring component driver 44 through the idler wheel 45, and then the stirring component driver 44 transmits it to the detection device 6. In some embodiments, the driving force delivered to the detection device 6 can also come directly from any one of the driving force receiver 41, the developing component driver 42, the powder feeding component driver 43, and the idler wheel 45. It is possible that the stirring component 33 can be configured to rotate around an axis parallel to the first direction, or it can be configured to reciprocate in a direction approximately parallel to the second direction. The driving force transmission method between the various driving components can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving component is configured as a gear.

[0145] The driving force receiving member 41 rotates about a second axis L2 parallel to the first direction. The detected member 9 is configured as a rod that can rotate about a third axis L3 parallel to the first direction, including a rotating part 93 and a first rod 91 and a second rod 92 connected to the rotating part 93. The second rod 92 is used to interact with the detection device 6, and the first rod 91 is used to be detected by the device.

[0146] [Detection Device]

[0147] The detection device 6 includes a drive assembly 61 disposed at the drive end, an action assembly 63 disposed at the detection end, and a transmission member 62 located between the drive assembly 61 and the action assembly 63. After receiving the driving force from the drive force transmission assembly 4, the drive assembly 61 drives the transmission member 62 to move in a direction not perpendicular to the first direction, thereby forcing the action assembly 63 to interact with the detected component 9. Preferably, the movement direction of the transmission member 62 is parallel to the first direction. More preferably, the transmission member 62 reciprocates in a direction parallel to the first direction. In this way, the detection end of the developing cartridge does not need to be equipped with components such as gears and ratchets for transmitting driving force, or the number of such components for transmitting driving force is reduced. The structure of the detection end is simplified, and when the developing cartridge is assembled, only the assembly of the drive end needs to be focused on. At the same time, based on the inventive concept of the present invention, the stirring member 33 no longer plays the role of transmitting driving force from the drive end to the detection end. Overall, the load on the stirring member 33 is effectively reduced, and therefore, the risk of breakage of the stirring member 33 is also greatly reduced.

[0148] In some embodiments, the transmission member 62 may also be configured such that at least a portion thereof reciprocates in a direction parallel to the first direction.

[0149] In the developing cartridge 1 equipped with the detection device 6, the problem of the delay in the transmission of driving force from the driving end to the detection end is solved, the detection accuracy can be improved, and at the same time, the torque of the developing cartridge 1 is greatly reduced, resulting in higher working stability.

[0150] [Driver Components]

[0151] The drive assembly 61 includes a drive member 612 and a counter member 613. The counter member 613 rotates about a fourth axis L4 parallel to the first direction, and at least a portion of the counter member 613 is closer to the housing 2 than the drive member 612. The drive member 612 is used to engage with the stirring drive member 44 and receive driving force. Along the first direction, at least a portion of the counter member 613 is closer to the housing 2 than the stirring drive member 44. Figure 4BAs shown, along the first direction, at least the portion of the counter 613 that interacts with the transmission member 62 (the protrusion described below) is closer to the housing 2 / left end face 21 / right end face 22 than the drive member 612 and / or the stirring member drive member 44. Preferably, the counter 613 as a whole is closer to the housing 2 / left end face 21 / right end face 22 than the drive member 612 and / or the stirring member drive member 44. Furthermore, along the first direction, at least a portion of the counter 613 is closer to the housing 2 / left end face 21 / right end face 22 than the idler wheel 45 / driving force receiver 41. In this way, the size of the developing cartridge 1 in the first direction can be reduced, which is beneficial for practical application. The developing cartridge 1 is now miniaturized; furthermore, the stirring drive 44 is installed by a deformable snap fastener, through which the stirring drive 44 has a certain displacement in the direction of its rotation axis. In this way, before the left end cover 27 is installed, the stirring drive 44 can prevent / block the counter 613 from falling off. When it is necessary to remove the counter 613, the stirring drive 44 is moved in the direction of its rotation axis by forcing the deformable snap fastener to undergo elastic deformation, so that the stirring drive 44 no longer prevents / blocks the counter 613, and the counter 613 can be removed in a smooth manner.

[0152] [Disconnect the driving force of the drive component]

[0153] The counting element 613 and the driving element 612 can be integrally formed or separate. After the detection is completed, the counting element 613 remains stationary by a separation mechanism provided in the developing cartridge 1. Specifically, when the counting element 613 and the driving element 612 are integrally formed, the counting element 613 as a whole will no longer receive driving force after the detection is completed. For example, the counting element 613 can be forced to move along the first direction or translated, so that the counting element 613 is detached from the driving source (any one of the driving force receiving element 41, developing element driving element 42, powder feeding element driving element 43, stirring element driving element 44, and idler wheel 45). In the case where the counting element 613 and the driving element 612 are formed separately, after the detection is completed, the counting element 613 and the driving element 612 may be disengaged, but the driving element 612 may not be disengaged from the driving source. Alternatively, the counting element 613 and the driving element 612 may be completely disengaged from the driving source. In some embodiments, regardless of whether the counting element 613 and the driving element 612 are formed integrally, the driving element 612 may be configured as a gear with a missing tooth. During the detection process, the gear part of the driving element 612 is opposite to the driving source and receives driving force. When the detection is completed, the missing tooth part of the driving element 612 is opposite to the driving source and does not receive driving force. The missing tooth part is a separation mechanism.

[0154] The counter 613 includes a chassis 613a, a connecting part 613b, a driving force receiving part 613c, and a plurality of protrusions provided on the chassis 613a. The counter 613 and the driving part 612 are connected to each other through the connecting part 613b. The driving force of the driving part 612 is transmitted to the counter 613 through the connection between the driving force output part 6122 provided on the driving part 612 and the driving force receiving part 613c provided on the counter 613.

[0155] When viewed along the rotation axis L4, the counter 613 is circular, and its radius R can vary between 10mm and 14mm, with an optimal value of 11mm to 13mm. Especially in structures with multiple gears at the drive end, if the diameter of the counter 613 is too large, it will be detrimental to the layout of other gears and lead to the failure of miniaturization of the developing cartridge 1. Conversely, if the diameter of the counter 613 is too small, the rotation speed of the counter 613 will increase, which will lead to increased wear between the components of the drive force transmission assembly 4 and may even cause the detection device 6 to fail.

[0156] When both the driving force receiver 41 and the driving member 612 are configured as gears, the gear tooth ratio between them is in the range of 0.7-1.3, preferably 0.8-1.1. In the case where the transmission member 62 adopts a translational scheme, this tooth ratio is beneficial for the miniaturization of the powder box end and improves the transmission accuracy.

[0157] Method 1

[0158] When the counter 613 and the drive 612 are separated, the separation mechanism includes an elastic pusher 611, a guide protrusion 613h on the counter 613, and a groove 615 that mates with the guide protrusion 613h. The counter 613 rotates around a column 614 on the housing 2. The groove 615 is located on the circumference of the column 614. One end of the elastic pusher 611 abuts against the counter 613, and the other end abuts against the left end cap 27. During the detection process, the guide protrusion 613h does not mate with the groove 615. Yes, the elastic pusher 611 is in an elastic deformation state. When the detection is completed, the guide protrusion 613h is opposite to the groove 615. Under the action of the elastic pusher 611, the counter 613 is forced to a position separated from the drive 612 along the first direction. At this time, the counter 613 is forced to a position closer to the housing 2. The position of the drive 613 relative to the housing 2 does not change. Therefore, even if the drive 613 is set as a full gear, the counter 613 will not be driven by the continuously rotating drive 613.

[0159] Method 2

[0160] Similar to Method 1, in this method, one end of the elastic pusher 611 abuts against the drive member 612, and the other end abuts against the left end cover 27. During the detection process, the elastic pusher 611 is in an elastic deformation state. When the detection is completed, the elastic pusher 611 releases its elastic force, causing the guide protrusion 613h to face the groove 615. The counter 613 and the drive member 612 are pushed together along the first direction to a position closer to the housing 2. At this time, the drive member 612 disengages from the drive source, and the counter 613 is no longer driven and remains stationary.

[0161] In this embodiment and in Method 1, the elastic pushing member 611 is configured as a compression spring. Alternatively, the elastic pushing member 611 can also be configured as a tension spring. In this case, one end of the tension spring is connected to the housing 2, and the other end is connected to the counter 613 or the driving member 612.

[0162] Method 3

[0163] As described above, the separation mechanism can also be a toothed gear provided in the drive member 612. In other embodiments, the separation mechanism can also be a pair of magnets. During the detection process, no magnetic force is generated between the pair of magnets. When the detection is completed, an attractive or repulsive force is generated between the pair of magnets, causing the counter 613 and the drive member 612 to separate / disengage from each other, or the counter 613 and the drive member 612 as a whole to disengage from the drive source.

[0164] Specifically, a first magnet is installed in the housing 2, and a second magnet is installed in the counting component 613. A repulsive force is generated between the pair of magnets. During the detection process, the pair of magnets are facing each other, and the counting component 613 can be combined with the driving component 612, or the counting component 613 and the driving component 612 as a whole are combined with the driving source. When the detection is completed, the repulsive force disappears, and under the action of the elastic pushing component 611, the counting component 613 and the driving component 612 separate / disengage from each other, or the counting component 613 and the driving component 612 as a whole disengage from the driving source.

[0165] Alternatively, the first magnet is mounted on the left end cover 27, while the second magnet remains mounted on the counter 613. An attraction is generated between the two magnets, greater than the elastic force of the elastic pusher 611. During detection, the counter 613 is driven by the drive 612. Upon completion of detection, the magnets are no longer facing each other, and the attraction disappears or decreases. Under the action of the elastic pusher 611, the counter 613 separates from the drive 612. Similarly, when the second magnet is mounted on the drive 612, upon completion of detection, the counter 613 and drive 612 are completely disengaged from the drive source.

[0166] When the detection device 6 is equipped with an elastic reset member 67, one end of the reset member 67 abuts against the transmission member 62 and the other end abuts against the housing 2. The reset member 67 can also be disposed between the actuating component 63 and the housing 2. The reset member 67 can be a compression spring or a tension spring. In the above implementation, the elastic force applied by the elastic pushing member 611 is greater than the elastic force of the reset member 67. When the elastic pushing member 611 pushes the counting member 613 and / or the driving member 612, the movement speed of the transmission member 62 will be accelerated. Ultimately, the rotation speed of the detected member 9 will also be accelerated, thus forming the phenomenon that the detected member 9 is accelerated.

[0167] Method 4

[0168] In this embodiment, the separation mechanism no longer includes an elastic pushing component, such as... Figure 5B As shown, the left end cover 27 is provided with a guide path 271 and a pushing surface 272 located in the groove-shaped guide path. The pushing surface 272 is set as an inclined surface, such as... Figure 5C As shown, the counter 613 also includes a guide block 613i disposed at the joint 613b. During the detection process, the guide block 613i is guided by the guide path 271. When the detection is about to be completed, the guide block 613i abuts against the pushing surface 272. As a result, the counter 613 and the drive 612 gradually disengage. During the disengagement process of the counter 613 and the drive 612, the inclined pushing surface 272 causes the rotation speed of the counter 613 to increase. Correspondingly, the movement speed of the transmission 62 to the right / detection end is also increased. Finally, the rotation speed of the detected item 9 also increases, thus creating the phenomenon that the detected item 9 is accelerated.

[0169] Method 5

[0170] In the above-mentioned method three, the acceleration process of the transmission member 62 / detected member 9 is achieved by the elastic force released by the elastic push member 611. However, alternatively, the acceleration process of the transmission member 62 / detected member 9 can also be achieved by the release of the elastic force by the reset member 67. For example, when the transmission member 62 moves downward from the protrusion of the counter member 613, the reset member 67 releases the elastic force, thereby forcing the transmission member 62 / counter member 613 to be accelerated.

[0171] [Structure of the counting component]

[0172] The plurality of protrusions include positioning protrusions 613d, first actuating protrusions 613e, and second actuating protrusions 613f, which are spaced apart along the circumference of the chassis 613a. There is a flat portion 613g between two adjacent protrusions. The first flat portion 613g1 is between the positioning protrusion 613d and the first actuating protrusion 613e, and the second flat portion 613g2 is between the first actuating protrusion 613e and the second actuating protrusion 613f. The number of actuating protrusions can be increased or decreased according to the detection requirements of the detection device. The following description uses a counter 613 with the first actuating protrusion 613e and the second actuating protrusion 613f as an example.

[0173] During the testing process, the first actuating protrusion 613e and the second actuating protrusion 613f sequentially contact the transmission component 62, thereby forcing the transmission component 62 to move to the right / to the testing end. Figure 6B As shown, each actuating protrusion includes a rising surface 613e1 / 613f1, a holding surface 613e2 / 613f2, and a falling surface 613e3 / 613f3. As the counter 613 rotates, when the rising surface 613e1 / 613f1 contacts the transmission member 62, the transmission member 62 will be gradually pushed to the right / detection end until the holding surface 613e2 / 613f2 contacts the transmission member 62. Finally, when the holding surface 613e2 / 613f2 disengages from the transmission member 62, the transmission member 62 disengages from the corresponding actuating protrusion and contacts the flat portion 613g.

[0174] The length of the rising surface 613e1 / 613f1 from its bottom to its top determines the distance the transmission member 62 moves to the right / detection end; the two are directly proportional. With a fixed height of the actuating protrusion, the larger the angle α1 / α2 between the rising surface 613e1 / 613f1 and the flat portion 613g, the shorter the stroke of the transmission member 62 and the faster it is pushed. Preferably, the holding surface 613e2 / 613f2 and the flat portion 613g are parallel to each other. The larger the size of the holding surface 613e2 / 613f2, the more the transmission member 62 is held. The longer the state time; as mentioned above, the flat part 613g is located between the two actuating protrusions. Therefore, the larger the size of the flat part 613g, the longer the time interval between the two pushes of the transmission member 62. It can be seen that the length of the rising surface 613e1 / 613f1 from the bottom to the top, the angle a1 / a2 between the rising surface 613e1 / 613f1 and the flat part 613g, the size of the holding surface 613e2 / 613f2, and the size of the flat part 613g may all be different according to the different detection requirements of the equipment. Designers can adjust them according to the detection requirements.

[0175] like Figure 6BAs shown, in some embodiments, the lengths of the first flat portion 613g1 and the second flat portion 613g2 can vary between 1mm and 10mm, preferably 3mm-4mm; the height of the holding surface 613e2 / 613f2, i.e., the value of the descending surface 613e3 / 613f3, can vary between 1mm and 10mm, preferably 3mm-6.5mm, and the height of the holding surface 613e2 of the first actuating protrusion is more preferably 4.5mm-6mm, and the height of the holding surface 613e2 of the second actuating protrusion is more preferably 4.5mm-6mm. The height of the holding surface 613f2 is more preferably 4.5mm-6.5mm; the angle a1 between the rising surface 613e1 of the first actuating protrusion and the flat portion 613g can vary between 5° and 85°, preferably between 25° and 65°, more preferably between 30° and 35°; the angle a2 between the rising surface 613f1 of the second actuating protrusion and the flat portion 613g can vary between 10° and 90°, preferably between 35° and 75°, more preferably between 60° and 70°. Specifically, in the rotation direction of the counting component 613, the first actuating protrusion 613e is located downstream of the second actuating protrusion 613f. In the structure that uses the actuating protrusion to drive the transmission component to move in the first direction, by studying the height, tilt angle and distance between adjacent actuating protrusions in detail, it can be ensured that the actuating protrusion and the transmission component cooperate more smoothly, the transmission is more stable, and the detection effect is better.

[0176] like Figure 6C As shown, in some other embodiments, the counter 613 is provided with three actuating protrusions, two of which have the same structure, for example, the structure of these two actuating protrusions is the same as that of the first actuating protrusion 613e mentioned above, and are referred to as the first actuating protrusion and the second actuating protrusion respectively in this embodiment. The other actuating protrusion has a different structure from the first actuating protrusion 613e, for example, the structure is the same as that of the second actuating protrusion 613f mentioned above, and is referred to as the third actuating protrusion in this embodiment. In this case, the counter 613 will form three flat portions, namely the first flat portion 613g1 located between the positioning protrusion 613d and the first actuating protrusion, the second flat portion 613g2 located between the first actuating protrusion and the second actuating protrusion, and the third flat portion 613g3 located between the second actuating protrusion 6 and the third actuating protrusion. Specifically, in the rotation direction of the counting component, the first and second actuating protrusions are located downstream of the third actuating protrusion, meaning that during the detection process, the transmission component 62 contacts the first, second, and third actuating protrusions in sequence.

[0177] During the detection process of the detection device 6, the effective detection angle a5 of the counter 613 (e.g., Figure 5DThe range (shown) is 200°-320°, preferably 250°-280°. By limiting the range to the above range by a5, it can be ensured that the transmission member 62 can be moved at least twice by the counting member 613 within the detection cycle of the detection device 6. Depending on the model of the developing cartridge 1, the number of times the counting member 613 is moved at least three times or more. The detection accuracy of the detection device 6 can be precisely controlled, and it is also beneficial to realize the miniaturization of the counting member 613.

[0178] Based on the above-described structure and motion process of the counter 613, the transmission ratio between the driving force receiving member 41 and the counter 613 varies between 0.05 and 0.5, preferably between 0.1 and 0.2. Setting the transmission ratio within the above range has the following beneficial effects:

[0179] This configuration allows the transmission component 62 to receive a stable driving force from the receiving and counting component 613, preventing problems such as accelerated wear between components due to excessive rotation speed, excessive stress concentration, or even breakage of the transmission component 613. At the same time, this configuration also prevents the counting component 613 from rotating too slowly, which would prevent the detection device 6 from interacting with the detected component 9 in a timely manner, thus not only wasting electricity and resulting in low detection efficiency, but also potentially causing the detection device 6 to fail.

[0180] [Structure and Installation of Transmission Components]

[0181] The transmission member 62 includes a forced pushing part 621 located at the driving end, a transmission part 623 located at the detection end, and a moving part 622 located between the forced pushing part 621 and the transmission part 623. Further, the detection device 6 also includes a reset member 67. When the transmission member 62 is pushed to the right / detection end, the reset member 67 accumulates a reset force. When the transmission member 62 is no longer pushed, the reset force forces the transmission member 62 to move / reset to the left / driving end. That is, the reset member 62 is set to reciprocate along the left-right direction / first direction. In some embodiments, the reset member 67 may not be a separate component. In this case, the reset of the transmission member 62 is driven / driven by the reset of the detected member 9, which in turn forces the transmission member 62 to reset.

[0182] like Figure 3 As shown, along a third direction, the housing 2 includes an upper housing 2a located above and a lower housing 2b located below, with the developer chamber 10 located between the upper housing 2a and the lower housing 2b, as... Figure 2 As shown, the guide groove 25 is located above the upper housing 2a and is exposed upwards. The transmission member 62 is movably installed in the guide groove 25. In this way, the transmission member 62 will not interfere with the developer when it moves, and the leakage of the developer is also avoided.

[0183] The developing cartridge 1 also includes a cover 24 to prevent the transmission component 62 from falling off. The cover 24 covers the guide groove 25 from above. On the one hand, the transmission component 62 will not fall off the guide groove 25, protecting the transmission component from external contact; on the other hand, it can improve the aesthetics of the developing cartridge. The cover 24 can be combined with the housing 2 by means of snap-fit, welding, bonding, magnetic attraction, etc.

[0184] The following describes the changes in the mounting structure and movement mode of the transmission component 62.

[0185] Change 1

[0186] like Figure 7 As shown, the transmission component 62 is generally plate-shaped, and the cover 24 is at least a pair of discontinuous protrusions provided on the upper housing 2a. The pair of discontinuous protrusions 24 are arranged opposite each other along a second direction. The opposite arrangement includes the case where the pair of discontinuous protrusions 24 are directly opposite each other and the case where they are misaligned in the second direction. The guide groove 25 is located between the pair of spaced protrusions 24. Furthermore, each discontinuous protrusion 24 also extends a limiting portion along the second direction toward the guide groove 25 to prevent the transmission component 62 from falling off.

[0187] Change 2

[0188] like Figure 8A As shown, the transmission member 62 is configured to rotate about an axis L6 that is not perpendicular to the third direction. The transmission member 62 reciprocates / oscillates along the second direction / front-back direction. Preferably, the rotation axis L6 of the transmission member 62 is parallel to the third direction. At least one pair of guide plates 252 protrude upward from the housing 2a. The guide groove 24 is located between the pair of guide plates 25. Similarly, in the second direction, the pair of guide plates 252 can be directly opposite each other or staggered. The rotation shaft 625 is provided in the moving part 622. The cover 24 covers the rotation shaft 625 to prevent the transmission member 62 from falling off.

[0189] When the forced pushing part 621 receives the forced pushing force, the transmission part 62 oscillates around the rotation axis L6. During this oscillation, the transmission part 623 interacts directly or indirectly with the tested part 9; such as Figure 8BAs shown, along the first direction, the end point of the transmission member 62 at the detection end is P. The dashed line in the figure shows the position of the transmission member 62 after swinging. Before swinging, the transmission member 62 is in the first position, and after swinging, the transmission member 62 is in the second position. Taking the surface 2a2 of the housing 2 / upper housing 2a at the detection end as the reference, it can be seen that when the transmission member 62 is in the first position, the end point P is at a distance h1 from the surface 2a2, and when the transmission member 62 is in the second position, the end point P is at a distance h2 from the surface 2a2. The h1 and h2 are not equal, and h1 is greater than h2. That is to say, during the detection process of the detection device 6, the transmission member 62 still has a movement distance along the first direction, or in other words, during the detection process of the detection device 6, at least a part of the transmission member 62 moves in the first direction. During the movement of the transmission member 62, the transmission member 62 interacts directly or indirectly with the detected object 9.

[0190] Change 3

[0191] like Figure 8C , Figure 8D and Figure 8E As shown, the transmission member 62 is configured to rotate about an axis L6' parallel to the second direction. The forced push part 621 moves upward first and then downward, and synchronously, the transmission part 623 moves downward first and then upward, thereby realizing the detection. That is, the transmission member 62 is configured to reciprocate / oscillate along the third direction / up and down direction. During the detection process of the detection device 6, when the forced push part 621 reaches the top, the distance from one end of the transmission member 62 to the rotation axis L6' in the first direction is d2, and when the forced push part 621 reaches the bottom, the distance from one end of the transmission member 62 to the rotation axis L6' in the first direction is d3, where d3 is less than d2.

[0192] Furthermore, to reduce the frictional force when the transmission component 62 moves, the developing cartridge also includes a plurality of protruding ribs 251 disposed in the guide groove 25. The plurality of protruding ribs 251 are arranged at intervals along the first direction. In this way, the contact area between the transmission component 62 and the guide groove 25 is reduced, and the frictional force between the two is also reduced. Alternatively, the protruding ribs 251 can also be disposed on the transmission component 62. Applying lubricating powder to the guide groove 25 or the transmission component 62 or replacing it with a material with a lower coefficient of friction (such as POM material) can also reduce the frictional force between the two and improve the transmission efficiency and detection accuracy.

[0193] [Structure of the functional component]

[0194] The actuating component 63 is configured to rotate about axis L5. During the rotation, the actuating component 63 interacts with the detected component 9. The axis of rotation of the actuating component 63 can be parallel to any one of the first direction, the second direction, and the third direction. In the following text, we take the example that the axis L5 is perpendicular to the first direction.

[0195] The actuating component 63 includes a rotating part 631, an actuating protrusion 632 extending from the rotating part 631, and a passive part 633. The actuating protrusion 632 is arranged in a non-linear manner along a direction perpendicular to the rotation axis L5; it can extend directly from the rotating part 631 or from the connecting part 636 connected to the rotating part 631. Figure 10A As shown, the actuating protrusion 632 is generally claw-shaped, and the groove / avoidance portion 6323 is provided in the actuating protrusion 632 and is recessed in a direction opposite to the rotation direction r3 of the actuating component 63. Figure 10B and Figure 10C As shown, when the actuating protrusion 632 rotates with the rotating part 631, the actuating part 6324 of the actuating protrusion 632 will directly contact the surface 921 of the second rod 92 facing the actuating protrusion 632 (e.g., Figure 12B (As shown) contact, without the action protrusion 62 first contacting the edge 922 and then contacting the surface 921, the edge 922 being the boundary line of the surface 921 near the side of the housing 2 / transmission member 62 / action component 63.

[0196] In the developing cartridge where the driving force transmission assembly 4 is entirely located at the driving end, the driving end experiences a large torque during operation. This may cause the right side / detection end of the developing cartridge to be higher than the left side / driving end. During detection, the actuating protrusion may contact different positions of the tested component 9, leading to detection errors. Therefore, in this embodiment, the actuating part 632 of the actuating protrusion 632, which abuts against the second rod 92, needs to be positioned closer to the free end 923 of the second rod 92. Thus, during the operation of the actuating assembly 63, in the third direction, when the contact position between the actuating part 6324 and the second rod 92 is higher than the predetermined position, a portion of the actuating protrusion 632 can be removed to return the contact position between the actuating part 6324 and the second rod 92 to the predetermined position. Figure 10A and Figure 10B As shown, two surfaces 6321 / 6322 of different heights are formed above the actuating protrusion 632, with a height difference between them. This allows the contact point between the actuating protrusion 632 and the second rod 92 to be lowered. Extending from this, when the actuating protrusion 632 is configured to contact different positions of the tested component 9, the rotation speed of the tested component 9 can be varied, thus achieving the same detection function.

[0197] like Figure 10DAs shown, along the radial direction of the rotating part 631, the actuating protrusion 632 has a farthest point M. With reference to this farthest point M, the angle that the actuating protrusion 632 can rotate in this embodiment is a4. The solid line in the figure represents the position where the actuating protrusion 632 is not touching the second rod 92, and the dashed line represents the position of the actuating protrusion 632 when the second rod 92 is moved to the predetermined position. The angle a4 can vary in the range of 20°-70°, preferably 30°-45°.

[0198] Figure 11A and Figure 11B Another structure of the functional protrusion 632 is shown. Unlike the above embodiment, the functional protrusion 632 in this embodiment has an inclined surface 632a and a plane 632b on the side facing the second rod 92. The groove / avoidance portion 6323 extends in the plane 632b and the inclined surface 632a in a third direction. When the functional protrusion 632 contacts the second rod 92, the edge 922 will not contact the functional protrusion 632, and the functional portion 6324 will directly contact the surface 921.

[0199] In one embodiment, the passive part 633 mates with the shaft hole of the transmission member 62. When the transmission member 62 reciprocates along a first direction, the passive part 633 and the transmission member 62 can move relative to each other. That is, the size of the hole is larger than the size of the shaft. Figure 7 As shown, the passive part 633 is configured as a shaft, and the transmission part 62 is provided with a hole 6231.

[0200] like Figure 9B As shown, hole 6231 is set as a square hole, and passive part 633 is a cylinder. Specifically, the diameter of cylinder 633 varies between 1mm and 8mm, preferably 2.5mm and 3.5mm. Along the first direction, the size of hole 6231 varies between 2mm and 8mm, preferably 3mm and 3.5mm. Along the second direction, the size of hole 6231 varies between 2mm and 10mm, preferably 4mm and 5mm. Alternatively, hole 6231 can also be a notch or a groove. Preferably, along the first direction, the size of hole 6231 is the same as the diameter of cylinder 633, thus avoiding any misalignment. Along the second direction, the size of hole 6231 is larger than the diameter of cylinder 633, thereby reserving space for the movement of cylinder 633. If the shaft size is too small, it will not only lack strength and be easily broken; if the size is too large, it will occupy a large space, which is not conducive to the miniaturization of the developing cartridge.

[0201] The following is combined Figure 13 , Figure 14A , Figure 14B and Figure 15 , Figure 16A , Figure 16B A modified embodiment of the functional component 63 is described.

[0202] Transformation 1

[0203] like Figure 13 As shown, the actuating component 63 includes an actuating member 634 rotatable about a rotation axis L5 and a movable member 64 for driving the actuating member 634. The movable member 64 includes a base 641 and a movable part 642 movable relative to the base 641. The movable part 642 is configured to rotate only in one direction. The actuating member 634 includes a central shaft 6340 and a first lever 6341, a second lever 6342, and a ratchet 6343 coupled to the central shaft. The ratchet 6343 is driven by the movable part 642. Preferably, the ratchet 6343 is located in the central shaft. At one end of the spindle 6340, the first lever 6341 and the second lever 6342 extend radially outward from the surface of the spindle 6340 along the rotation axis L5. The first lever 6341 and the second lever 6342 are distributed at different axial positions, that is, the distance between the first lever 6341 and the second lever 6342 and any end of the spindle 6340 is different, or in other words, the first lever 6341 and the second lever 6342 have a height difference. Thus, the first lever 6341 and the second lever 6342 move the detected part 9 to different positions.

[0204] During the testing process, the transmission unit 623 moves to the right / test end and pushes the movable member 64. Subsequently, the movable member 642 pushes the ratchet 6343 to rotate, and the first lever 6341 or the second lever 6342 abuts against the second lever 92. When the transmission unit 623 stops pushing the movable member 64, the movable member 64 is pushed back to its original position by a component such as an elastic member. Figure 14A As shown, the first lever 6341 contacts the surface 921 of the second lever at point Q1. As the ratchet 6343 is turned, the tested component 9 is pushed to rotate around the rotating part 93 in the direction shown by r until the first lever 6341 disengages from the second lever 92. As the ratchet 6343 continues to rotate, the second lever 6342 begins to contact the second lever 92 at point Q2. Compared to point Q1, point Q2 is farther away from the free end 923 of the second lever 92. That is to say, point Q2 is closer to the rotating part 93 than point Q1. With the rotational speed of the ratchet 6343 remaining constant, the tested component 9 will rotate faster under the push of the second lever 9342, thus creating the phenomenon of the tested component 9 being accelerated.

[0205] For the movable member 64, after the movable part 642 pushes the ratchet 6343, during the process of the elastic member forcing the movable member 64 to reset, the movable part 642 is supported by the ratchet 6343 and rotates, so that the movable part 643 can move into the position to push the ratchet 6343 again. In some embodiments, the movable member 64 is connected to the transmission part 623 and can move with the movement of the transmission part 623.

[0206] Transformation 2

[0207] In this modified embodiment, the actuating component 63 is configured as a rotating component that can rotate about an axis not perpendicular to the first direction, including a central shaft 635, a guide path 6351 disposed on the central shaft 635, a guide inclined surface 6352 located on the guide path, and a lever 6353 connected to the central shaft 635. The transmission component 62 is still configured to reciprocate in a direction not perpendicular to the first direction. The transmission part 623 of the transmission component 62 is configured to be guided by the guide path 6351. Preferably, the guide path 6351 is a groove disposed on the central shaft 635, and the guide inclined surface 6352 is disposed in the groove 6351.

[0208] like Figure 16A , Figure 16B , Figure 17A and Figure 17B When the transmission member 62 moves to the right / detection end, the transmission part 623 presses against the guide slope 6352, and the rotating member 63 is forced to rotate around its axis in the direction shown by r1. At the same time, the lever 6353 moves the second lever 92 of the detected member 9. When the transmission member 62 moves to the left / drive end, the transmission part 623 no longer presses against the guide slope 6352. Under the action of an elastic element, the rotating member 63 returns to its original position, and the lever 6353 no longer moves the second lever 92.

[0209] Transformers 3

[0210] In this modified embodiment, the transmission member 62 directly actuates the detected member 9; or, the actuating component 63 is integrally formed with the transmission member 62. In this case, the detection device 6 can also be considered to no longer have the actuating component 63. Figure 18 , Figure 19A and Figure 19B As shown, the transmission part 623 of the transmission component is provided with an arc surface / inclined surface 6232. As the transmission component 62 moves to the right / detection end, the arc surface / inclined surface 6232 contacts the second rod 92 of the tested component and pushes the tested component 9 to rotate around the rotating part 93.

[0211] The arc / sloping surface 6232 has a first end 6232a and a second end 6232b. Along the first direction, the first end 6232a is further away from the moving part 622 / forced pushing part 621 than the second end 6232b. In this way, during the movement of the transmission member 62 to the right / detection end, the transmission part 623 / arc / sloping surface 6232 can smoothly actuate the second rod 92. When the transmission member 62 returns to the left / drive end, the transmission part 623 / arc / sloping surface 6232 is still in contact with the second rod 92, so that the second rod 92 can return to its original position smoothly.

[0212] Transformers 4

[0213] In this modified embodiment, the actuating component 63 and the transmission component 62 are connected by a gear and rack mechanism, such as... Figure 20A , Figure 20B , Figure 21A and Figure 21B As shown, the transmission part 623 is configured as a rack, and the actuating component 63 includes a rotating part 631, an actuating protrusion 632 connected to the rotating part 631, and a driven part 633. The driven part 633 is configured as a gear, preferably with the rotating part 631 and the gear 633 coaxially arranged. When the transmission member 62 is pushed to the right / detecting end, the rack drives the gear to rotate, which in turn causes the rotating part 631 to swing the actuating protrusion 632. During the swinging of the actuating protrusion 632, the second rod 92 is actuated.

[0214] Change 5

[0215] In this modified configuration, the actuating component 63 is configured to oscillate along the vertical / third direction, such as... Figure 11C , Figure 11D and Figure 11E As shown, the actuating component 63 swings about the rotation axis L5' extending in the front-back direction / second direction. In the first direction, when the transmission member 62 moves toward the detection end, the actuating component 63 is pushed by the transmission member 62 and swings about the rotation axis L5'. During the swinging process of the actuating component 63, the second rod 92 is deflected.

[0216] exist Figure 11C , Figure 11D and Figure 11E In the structure shown, the actuating component 63 can be in a naturally drooping state due to its own gravity. When the actuating component 63 is pushed by the transmission member 62, in Figure 11C In this modified version, the actuating component 63 swings counterclockwise around the rotation axis L5'. The actuating protrusion 632 in the actuating component 63 pushes the second rod 92. When the transmission component 62 resets towards the driving end, the actuating component 63 resets under its own gravity. It can be seen that in this modified version, it is not necessary to set a component in the actuating component 63 to force it to reset. Therefore, the structure of the actuating component 63 becomes simple.

[0217] Change 6

[0218] The above-described embodiment describes that the actuating component 63 is pushed or actuated by the transmitting component 62, so that the actuating component 63 actuates the detected component 9 by rotating or swinging around the rotation axis L5 / L5'. That is, the movement trajectory of the actuating protrusion 632 is a curve. However, the actuating component 63 can also be set to have a straight movement trajectory.

[0219] For example, a magnetic component is provided between the transmission component 62 and the action component 63. When the transmission component 62 moves, the magnetic force generated by the magnetic component forces the action component 63 to move, thereby realizing the interaction between the action component 63 and the detected component 9. When the magnetic force decreases or disappears, the action component 63 is reset by the action of a separately provided reset component or by the action of the detected component 9. During this process, the movement trajectory of the action component 63 can be either a curve or a straight line.

[0220] When the movement trajectory of the actuating component 63 is a straight line, the actuating protrusion 632 can directly contact the surface 921. At this time, the actuating protrusion 632 does not need to be provided with a clearance part. It can be seen that the structure of the actuating protrusion 632 will become simple.

[0221] [Resetting the counter]

[0222] like Figure 5B , Figure 5C As shown, the left end cover 27 is provided with a first indicator 273, the drive member 612 is provided with a second indicator 6121, and the counter member 613 is provided with a third indicator 613d1. Before the detection device 6 starts detection, or after the detection device 6 is reset, the first indicator 273, the second indicator 6121, and the third indicator 613d1 are always approximately aligned along the first direction. The shapes of the first indicator 273, the second indicator 6121, and the third indicator 613d1 can be, for example, protrusions, grooves, teeth, arrows, etc., as long as they can serve an indicating function.

[0223] To facilitate the reset of the counter 613, the positioning protrusion 613d of the counter 613 is also provided with a force-applying part 613j. For example, the force-applying part 613j is a groove provided in the positioning protrusion 613d, or a protrusion provided in the positioning protrusion 613d. At least a part of the force-applying part is exposed. When it is necessary to reset the detection device, the rotation actuation component 63 causes the transmission component 62 to rotate around the axis. At the same time, the force is applied to the force-applying part 613j, so that the first indicator 273, the second indicator 6121 and the third indicator 613d1 are aligned along the first direction.

[0224] Furthermore, to prevent unnecessary movement of the transmission member 62, the positioning protrusion 613d is also provided with a limiting part. Preferably, the limiting part coincides with the third indicator part 613d1 to simplify the structure of the counting member 613. More preferably, the limiting part is a limiting groove.

[0225] Furthermore, such as Figure 5A and Figure 22As shown, at the drive end, the end face (left end face) of the upper housing 2a is not a single plane. Along the first direction, the left end face of the upper housing 2a includes a first left end face 2L1 and a second left end face 2L2. The second left end face 2L2 is closer to the detection end than the first left end face 2L1. An exposed portion 2c is formed between the first left end face 2L1 and the second left end face 2L2. Along the first direction, the exposed portion 2c is located between the right end 274 of the end cover 27 and the second left end face 2L2. At least a part of the counter 613 is exposed to the outside through this exposed portion. On the one hand, the user can observe whether the detection device has been reset through the exposed portion 2c. On the other hand, the exposed portion 2c also provides space for the counter 613 to move towards the housing 2, so that the counter 613 does not have to be set further to the left, which can reduce the size of the developing cartridge in the first direction.

[0226] Preferably, the exposed part 2c is exposed upwards, which is more conducive to user observation. Furthermore, the force-applying part 613i of the counter 613 is also exposed through the exposed part 2c, so the end cover 27 does not need to open a separate opening for resetting the counter 613. The user can reset the detection device 6 by applying force to the force-applying part 613i through the exposed part 2c. Furthermore, the protrusions 613d / 613f of the counter 613 are set to face or face away from the housing 2, that is, the counter 613 is located between the left end cover 27 and the housing 2. In this way, the protrusions 613d / 613f can be effectively protected by the left end cover 27, the drive member 612 and the housing 2.

[0227] [Delayed motion of the counting component]

[0228] In some embodiments, the detected element 9 is configured to be driven by the driving force receiver 41 for a period of time before it is started to be moved. In this case, the rotational motion of the counter 613 needs to have a delay, that is, the driving force received by the driving force receiver 41 is not immediately transmitted to the counter 613.

[0229] In a feasible manner, along the rotation direction of the counter 613, the driving force output part 6122 of the drive member 612 and the driving force receiving part 613c provided in the counter 613 are spaced at a predetermined distance. In this way, when the drive member 612 starts to rotate, the driving force is not immediately transmitted to the counter 613. The counter 613 remains stationary. The counter 613 only starts to rotate when the driving force output part 6122 contacts the driving force receiving part 613c. The delay requirement of the counter 613 is achieved.

[0230] like Figure 23As shown, the description takes the example of the driving member 612 being driven by the stirring rack gear 44, and the counting member 613 being integrally formed with the driving member 612. The stirring rack gear 44 is configured as a double gear. Along the first direction, the stirring rack gear 44 includes a first gear 441 located on the left and a second gear 442 located on the right. The first gear 441 is a full-tooth gear, used to receive the driving force from the driving force receiving member 41. The second gear 442 is also a full-tooth gear, used to be opposite to the driving member 612 and to transmit the driving force to the driving member 612.

[0231] The driving component 612 is a toothed gear, meaning that on the same circumferential surface of the driving component 612, a portion of the circumferential surface of the driving component 612 is provided with teeth to form a toothed portion 612a, and another portion is without teeth to form a toothed portion 612b. Along the first direction, an intermediate portion 443 is formed between the first gear 441 and the second gear 442, and a moving portion 4411 is provided in the intermediate portion 443. Corresponding to the moving portion 4411, the driving component 612 is provided with a moved portion 612c. When the developing cartridge is assembled, along the first direction, the moving portion 4411 and the moved portion 612c are both located between the first gear 441 and the second gear 442. The moved portion 612c is located on the rotation path of the moving portion 4411, and the toothed portion 612b is opposite to the second gear 442. That is to say, even if the stirring rack gear 44 starts to rotate along the rotation direction r2 around the rotation axis L7, the driving component 612 will not be driven.

[0232] As the stirring rack gear 44 continues to rotate, the actuating part 4411 begins to actuate the actuated part 612c. At this time, the driving member 612 begins to rotate. When the actuating part 4411 disengages from the actuated part 612c, the toothed part 612a begins to mesh with the second gear 442. Thus, the driving member 612 / counting member 613 is driven by the stirring rack gear 44, and subsequently, the detected part 9 begins to be detected. The delay time of the driving member 612 / counting member 613 is the time required for the actuating part 4411 to begin contacting the actuated part 612c as the stirring rack gear 44 begins to rotate. It is understandable that the designer can also adjust the position of the actuating part 4411 according to the delay requirements of the equipment for the detected part 9, so that the moment when the actuating part 4411 begins to contact the actuated part 612c changes.

[0233] Preferably, the actuating part 4411 is integrally formed with one of the teeth of the first gear 441, thereby enhancing the strength of the actuating part 4411. Along the first direction, the actuating part 4411 is positioned closer to the second gear 442 than the teeth of the first gear 441.

[0234] [Acceleration of the tested item]

[0235] As described above, in some embodiments, the tested item 9 needs to be accelerated and moved when the detection period of the detection device 6 is about to end (the final stage of detection); otherwise, the developing cartridge will not be recognized by the device. To achieve the acceleration of the tested item 9, it can be achieved by accelerating the counter 613, accelerating the transmission 62, or moving the second lever 92 to different positions, as described above. Other implementation methods are described below.

[0236] Method 1

[0237] The following is combined Figure 24 , Figure 25A and Figure 25B Another way to speed up the counter 613 is described.

[0238] In this embodiment, the counting component 613 and the driving component 612 are still integrated as an example. The driving component 612 is configured as a toothed gear. Furthermore, the driving component 612 also includes an arc surface 6124 coaxially arranged with the toothed gear and a straight surface 6125 adjacent to the arc surface. The elastic pushing component 611 is configured as a torsion spring. One end of the torsion spring abuts against the driving component 612, and the other end abuts against the component other than the driving component 612.

[0239] like Figure 25A As shown, before the detection device 6 reaches the final detection stage, the torsion spring 611 abuts against the arc surface 6124 and does not hinder the rotation of the drive member 612. When the detection device 6 reaches the final detection stage, the torsion spring 611 disengages from the arc surface 6124 and begins to abut against the straight surface 6125. During the process of the torsion spring 611 changing its contact surface, the torsion spring 611 releases torque, thereby forcing the drive member 612 to accelerate its rotation. Furthermore, the drive member 612 is also provided with an opening 6123 to facilitate the user to reset the torsion spring 611 from the outside.

[0240] Method 2

[0241] The acceleration of the drive member 612 can also be achieved by setting the second gear 442 of the stirring rack gear 44 as a toothless gear, with the diameter of the second gear 442 being smaller than the diameter of the first gear 441. At the same time, the drive member 612 is also set as a double gear. Along the first direction, the drive member 612 has a main gear that meshes with the first gear 441 and a secondary gear that is opposite to the second gear 442. During the detection process, the first gear 441 drives the main gear to rotate. When it reaches the detection end of the detection device 6, the first gear 441 disengages from the drive gear, and the second gear 442 begins to mesh with the secondary gear. Since the diameter of the second gear 442 is smaller than the diameter of the first gear 441, the drive member 612 will be accelerated when the second gear 442 drives the secondary gear.

[0242] Example 2

[0243] like Figures 26-32B As shown, based on Embodiment 1, this embodiment further optimizes the structure of the detection device 6 to further improve the detection accuracy of the detection device.

[0244] Regarding the acceleration of the tested component 9, based on the above-mentioned [driving force cut-off of the driving component] method four, this embodiment provides the following acceleration method.

[0245] like Figure 26 As shown, the driving member 612 and the counting member 613 are formed separately and rotate around the rotation axis L4. Along the rotation axis L4, the counting member 613 is closer to the housing 2 / detection end than the driving member 612. The elastic pushing member 611 is disposed between the counting member 613 and the left end cover 27. The guide path 271 is disposed along the rotation direction of the counting member 613. Similarly, the groove 615 is disposed on the guide path 271, and the groove 615 has an inclined surface / pushing surface 272 that is inclined relative to the rotation axis L4. During the detection process of the detection device 6, the counting member 613 moves along the guide path 271. When the detected item 9 needs to be accelerated, a part of the counting member 613 reaches the inclined surface 272, and the elastic pushing member 611 releases its elastic force, so that the counting member 613 accelerates its rotation while continuing to move along the inclined surface 272. At the same time, the counting member 613 forces the transmission member 62 to also accelerate. Finally, the accelerated movement of the detected item 9 can be realized; the acceleration process will be described below.

[0246] As described in Embodiment 1 [Delayed Movement of the Counter], when the drive member 612 and the counter member 613 are formed separately, a drive force output section 6122 (e.g., ...) can be provided in the drive member 612. Figure 32B As shown, a driving force receiving part 613c is provided in the counter 613. The driving force is transmitted through the combination of the driving force output part 6122 and the driving force receiving part 613c. When the counter 613 needs to be delayed, that is, when the rotation time of the counter 613 needs to be later than the rotation time of the driving part 612, the driving force output part 6122 can be configured such that the driving force output part 6122 and the driving force receiving part 613c are not combined during the period when the driving part 612 is driven to start rotating a predetermined angle. The driving force output part 6122 and the driving force receiving part 613c only start to combine after the driving part 612 has rotated to the predetermined angle.

[0247] like Figure 27As shown, the counter 613 includes a chassis 613a, a connecting portion 613b, a driving force receiving portion 613c, and a plurality of protrusions 613d-613f disposed on the chassis 613a. At least a portion of the connecting portion 613b enters the driving member 612 to achieve the connection between the two. Preferably, the driving force receiving portion 613c and the plurality of protrusions 613d-613f are respectively disposed on both sides of the chassis 613a. Preferably, the driving force receiving portion 613c is disposed on the side of the chassis 613a facing the driving member 612.

[0248] Furthermore, the counter 613 is also provided with a guide protrusion 613h that can be guided by the guide path 271, such as Figure 27 As shown, the guide protrusion 613h is arranged on the same side as multiple protrusions 613d-613f. Along the radial direction of the chassis 613a, the guide protrusion 613h is located radially inside the multiple protrusions. This design helps to reduce the size of the counter 613 in the radial direction. Correspondingly, the multiple protrusions 613d-613h are located outside the guide path 272 in the radial direction. This structure can also avoid interference between the guide protrusion 613h and the transmission component 62. Furthermore, along the rotation axis L4, the extension dimension of any one of the multiple protrusions 613d-613f is greater than the extension dimension of the guide protrusion 613h. That is, any one of the multiple protrusions 613d-613f is farther away from the chassis 613a or closer to the detection end than the guide protrusion 613h. This design can also reduce the size of the counter 613 in the direction of the rotation axis L4. Therefore, the overall size of the counter 613 can be effectively controlled, which is beneficial to the miniaturization of the developing cartridge.

[0249] In some embodiments, to prevent the counter 613 from being reversed, for example, during the transportation of the developing cartridge, when the user installs the developing cartridge into the device but has not yet started using it, if the counter 613 is shaken and reversed, the detection process of the detection device 6 will fail.

[0250] Therefore, the detection device 6 involved in this embodiment also includes a first positioning part 613k. When the developing cartridge is assembled, the first positioning part 613k abuts against the first abutting part other than the counter 613. That is, the reverse rotation of the counter 613 (rotation in the opposite direction to the predetermined direction) is stopped by the abutting between the first positioning part 613k and the first abutting part.

[0251] Preferably, the first abutment is an abutment protrusion 275 provided on the left end cover 27. The abutment protrusion 275 is formed as a cantilever on the left end cover 27, having an abutment surface 2751 parallel to the rotation axis L4 and an inclined surface 2752 adjacent to the abutment surface 2751. The abutment surface 2751 abuts against the first positioning part 613k, and the reverse rotation of the counter 613 can be prevented. When the counter 613 rotates in a predetermined direction, the counter 613 can be guided by the inclined surface 2752 to force the abutment protrusion 275 to undergo elastic deformation, allowing the counter 613 to pass. In some embodiments, the first positioning part 613k is provided at the end of the joint 613b away from the chassis 613a.

[0252] Furthermore, in some embodiments, to prevent possible rotation of the counter 613 in a predetermined direction when the counter 613 does not need to start working, the detection device 6 further includes a second positioning part 613d2. The second positioning part 613d2 abuts against a second abutting part other than the counter 613, that is, the forward rotation (rotation in a predetermined direction) of the counter 613 is stopped by the abutting between the second positioning part 613d2 and the second abutting part; preferably, the second positioning part 613d2 is provided on one of the plurality of protrusions.

[0253] Along the rotation direction r of the counter 613, the positioning protrusion 613d, the first actuating protrusion 613e, and the second actuating protrusion 613f among the plurality of protrusions 613d-613f are arranged in sequence at intervals. The second positioning part 613d2 is provided on the positioning protrusion 613d and the counter 613 is positioned by abutting against the transmission member 62 (an embodiment of the second abutting part). Along the rotation direction r4 of the counter 613, the second positioning part 613d2 is located at the downstream end of the positioning protrusion 613d.

[0254] The detection process of the detection device 6 in this embodiment is described below with reference to the accompanying drawings.

[0255] Based on the above-mentioned [Structure and Installation of Transmission Components] Change 2, such as Figure 28A As shown, in this embodiment, the transmission member 62 is also configured to rotate about the rotation axis L6, and the action component 63 for interacting with the detected component 9 is configured to rotate about the rotation axis L5 as described above, and there is a rotatable connection between the transmission member 62 and the action component 63.

[0256] When the developing cartridge is assembled, the second indicator 6121 on the drive member 612 and the first indicator 273 on the left end cover 27 are aligned. The first positioning part 613k abuts against the first abutting part 275 on the left end cover 27. At the same time, the second positioning part 613d2 abuts against the transmission member 62 (specifically, the forced pushing part 621 of the transmission member). With the rotation axis L6 as the boundary, the side where the forced pushing part 621 of the transmission member 62 is located (left side 62a) is pushed towards one end 53 (front of the developing cartridge) in the second direction, and the side where the transmission part 623 of the transmission member 62 is located (right side 62b) is pushed towards the other end 54 (rear of the developing cartridge) in the second direction. The reset member 67 undergoes elastic deformation. In this way, the forward and reverse rotation of the counting member 613 is stopped, and the transmission member 62 is also kept in the posture of the left side 62a forward and the right side 62b backward.

[0257] like Figure 28C As shown, the transmission member 62, which is held in the above posture, rotates the pulling component 63 around the rotation axis L5 by an angle. The action protrusion 632 abuts against the second rod 92 of the detected component and forces the detected component 9 to rotate (the deviation position of the detected component 9). This achieves the function that when the developing cartridge is just installed in the predetermined position of the equipment, the detected component 9 can be turned once and held in the turned position. Thus, the installation of the developing cartridge can be detected by the equipment.

[0258] like Figure 28B As shown, before the counter 613 starts working, the positioning protrusion 613d among the multiple protrusions abuts against the forced push part 621 through the second positioning part 613d2 disposed therein, and the guide protrusion 613h is located downstream of the groove 615 along the rotation direction r4.

[0259] When the driving force receiver 41 receives the driving force and begins to rotate, the driving member 612 is driven. As described above, the driving force output part 6122 abuts against the driving force receiver 613c, and the counting member 613 is driven to rotate around the rotation axis L4 in the direction shown by r4. Figure 29A As shown, after the positioning protrusion 613d disengages from the forced push part 621, the reset member 67 releases its elastic force, and the transmission member 62 rotates around the rotation axis L6. The left side 62a of the transmission member moves towards the rear of the developing cartridge, and the right side 62b of the transmission member moves towards the front of the developing cartridge, as shown. Figure 29B As shown, the forced push part 621 enters between the positioning protrusion 613d and the first actuating protrusion 613e. At the same time, the transmission part 623 drives the actuating component 63 to rotate around the rotation axis L5, and the actuating protrusion 632 no longer forces the second rod 92, as... Figure 29C As shown, the detected component 9 returns to a non-deviation position, which is different from the deviation position.

[0260] As the counter 613 continues to rotate, as Figure 30A and Figure 30B As shown, the first actuating protrusion 613e begins to abut against the forced push portion 621, thus causing the transmission member 62 to return to its original position. Figure 28A As shown in the diagram, correspondingly, the detected component 9 also returns to its original state. Figure 28C The deviation position is shown; subsequently, the second actuating protrusion 613f and the positioning protrusion 613d also abut against the forced push part 621 respectively. It is understood that each of the plurality of protrusions abuts against the forced push part 621 once, and the actuating protrusion 632 abuts the second lever 92 once. Therefore, the number of the plurality of protrusions can be set according to the needs of the equipment.

[0261] like Figure 31A , Figure 31B , Figure 32A and Figure 32B As shown, when the guide protrusion 613h also reaches the edge of the groove 615, under the elastic force released by the elastic pushing member 611, the guide block 613i slides quickly along the inclined surface 272. Correspondingly, the rotation speed of the counting member 613 also increases. Through the positioning protrusion 613d, the transmission member 62 and the action component 63, finally, the detected member 9 quickly returns from the non-deviation position to the deviation position. The acceleration requirement of the detected member 9 is realized. At the same time, the detection device 6 achieves high-precision detection.

[0262] In some embodiments, after the detected element 9 accelerates, it needs to return from the deviated position to the non-deviated position. In this case, the positioning protrusion 613d is set to disengage from the forced push part 621. Conversely, in some embodiments, after the detected element 9 accelerates, it still needs to remain in the deviated position. In this case, the positioning protrusion 613d will be set to remain in contact with the forced push part 621.

[0263] Furthermore, while the elastic pushing member 611 pushes the counting member 613 towards the housing 2 / detection end, the driving force output part 6122 and the driving force receiving part 613c will separate from each other, as... Figure 32B As shown, along the rotation axis L4, the driving member 612 and the counting member 613 separate, causing the transmission of driving force between them to be interrupted. Even if the driving member 612 continues to rotate, the counting member 613 will remain stationary. Correspondingly, the transmission member 62, the action component 63, and the detected member 9 will all remain stationary. In some embodiments, the detection device 6 can also be configured such that, upon completion of detection, the elastic pushing member 611 simultaneously pushes the driving member 612 and the counting member 613. At this time, the driving member 612 no longer receives driving force and remains stationary.

[0264] Example 3

[0265] like Figures 33-47As shown, based on the above embodiments, this embodiment further optimizes the structure of the detection device 6 to further improve the detection accuracy of the detection device and enhance the miniaturization level of the developing cartridge.

[0266] like Figure 33 As shown, the driving element 612 and the counting element 613 are still configured as two separate components. The driving element 612 still rotates about the rotation axis L4, and the counting element 613 is configured to rotate about a rotation axis L8 that intersects the rotation axis L4. Preferably, the rotation axes L4 and L8 are perpendicular to each other. With this configuration, the size of the detection device 6 can be reduced along the first direction, while the counting element 613 can be placed in a direction intersecting the first direction according to the overall structure of the developing cartridge.

[0267] like Figure 34 As shown, the drive unit 612 includes a base 6120, a drive force input unit 6128 located on both sides of the base 6120, and a drive force output unit 6122. The drive force input unit 6128 receives the drive force from the drive force receiving unit 41. Commonly, the drive force input unit 6128 is a full-tooth gear or a cylinder with a rough surface, as long as it can receive the drive force. The drive force output unit 6122 is a bevel gear. Thus, the drive force output unit 6122 outputs the drive force... Force can change the direction of rotation, so that the driving force can be transmitted from the driving member 612 to the counting member 613. Furthermore, the driving member 612 also includes a third abutting part 6127 disposed on the base 6120, similar to the first abutting part 275 described above. Preferably, the third abutting part 6127 is a cantilever disposed on the base 6120, and the third abutting part 6127 is also provided with the abutting surface and the inclined surface. Thus, the third abutting part 6127 can both prevent the counting member 613 from rotating in the opposite direction and will not hinder the forward rotation of the counting member 613.

[0268] Preferably, the driving force output component 6128 is a spur gear with the following parameters: 28 teeth, a module of 0.8, and a pressure angle of 20°; the bevel gear 6122 has the following parameters: 15 teeth, a module of 0.9, a root circle radius of 0.2, a pressure angle of 20°, and a pitch cone angle of 45°. Specifically, those skilled in the art can appropriately adjust the above parameters according to design requirements to achieve the inventive objective of the present invention without changing the inventive concept.

[0269] In some embodiments, the counter 613 needs to be delayed, similar to what is described above in [Delayed movement of the counter]. The actuating part 4411 is provided in the driving member 612, and correspondingly, the counter 613 is provided with a actuated part 612c that can be actuated by the actuating part 4411, which will be described in detail below.

[0270] In some embodiments, at the end of the detection phase, the detected item 9 also needs to be accelerated, which is reflected in the detection device 6, such as... Figure 34 As shown, the driving unit 612 is also provided with a trigger 6126 that forces the counter 613 to accelerate. Correspondingly, the counter 613 is provided with a triggered element 613q that can be triggered by the trigger 6126, which will be described in detail below.

[0271] like Figures 35A-35D As shown, the counter 613 includes a chassis 613a, a connecting portion 613b, a driving force receiving portion 613c, and a plurality of protrusions 613d-613f disposed on the chassis 613a. The connecting portion 613b is used to connect the counter 613 to the housing 2, so that the counter 613 can rotate around the rotation axis L8 in the direction shown by r5. Along the rotation direction r5, the positioning protrusion 613d, the first actuating protrusion 613e, and the second actuating protrusion 613f are arranged alternately in sequence. The driving force receiving portion 613c, which is used to connect with the driving force output portion 6122, is disposed on the circumference of the connecting portion 613b. Specifically, the driving force receiving portion 613c is disposed on a portion of the circumferential surface of the connecting portion 613b. The bevel tooth (toothed portion) 612a, along the circumferential direction of the joint portion 613b, the portion without the bevel tooth 612a is the toothless portion 612b; further, the counting member 613 also includes a positioning post 613p protruding from the chassis 613a in the opposite direction to the joint portion 613b. Through the joint portion 613b and the positioning post 613p, the counting member 613 can be stably positioned in a rotatable manner. The triggered member 613q is provided on the circumferential surface of the positioning post 613p. Preferably, both the trigger member 6126 and the triggered member 613q are set as protrusions, that is, the trigger member 6126 protrudes from the base 6120, and the triggered member 613q protrudes from the chassis 613a or the positioning post 613p.

[0272] Preferably, the bevel tooth 612a has 8 teeth, a module of 0.9, a root circle radius of 0.2, a pressure angle of 20°, and a pitch cone angle of 45°, while the angle corresponding to the missing tooth portion 612b is 168°. Specifically, those skilled in the art can adjust the above parameters appropriately according to design requirements to achieve the inventive objective of the present invention without altering its conceptual design; more preferably, the transmission ratio between the driving member 612 and the counting member 613 is 1:1.

[0273] In this embodiment, the triggered element 613q and the actuated part 612c are respectively arranged on both sides of the chassis 613a. In this way, the structure of the counter 613 is more evenly distributed, and the triggered element 613q and the actuated part 612c will not interfere with each other during operation.

[0274] Preferably, along the rotation direction r5, the surface (triggered surface) 613q1 of the triggered element 613q used for being triggered by the triggered element 6126 is an inclined surface, that is, the tangent line of the circle containing the rotation direction r5 passing through the point of the triggered surface 613q1 is not perpendicular to the triggered surface 613q1. Taking the tangent line U passing through the endpoint F as an example, such as... Figure 35C As shown, the triggered surface 613q1 is simplified to a line segment EF. The line connecting the endpoint E of the line segment EF to the rotation axis L8 and the line connecting the endpoint F of the line segment EF to the rotation axis L8 do not coincide. Along the rotation direction r5, the line connecting the endpoint E to the rotation axis L8 is located downstream of the line connecting the endpoint F to the rotation axis L8. In other words, the angle between the tangent U and the line segment EF is an acute angle. This design is beneficial for the trigger 6126 to quickly separate from the triggered element 613q. Conversely, when the counter 613 needs to be accelerated for a longer period of time, the angle between the line segment EF and the tangent U can be adjusted. It is understood that the larger the angle between the line segment EF and the tangent U, the later the trigger 6126 separates from the triggered element 613q. Therefore, the position and shape of the triggered element 613q, especially the triggered surface 613q1, can be set according to the situation where the counter 613 needs to be accelerated.

[0275] Similar to the embodiments described above, the counter 613 in this embodiment is also provided with a positioning component to prevent reverse rotation, such as... Figure 35A As shown, the counter 613 also includes a third positioning part 613d3 and a fourth positioning part 613d4 disposed on the positioning protrusion 613d, and a fifth positioning part 613m and a sixth positioning part 613n disposed on the positioning post 613p. The third positioning part 613d3 and the fifth positioning part 613m are used to position the starting position of the counter 613, and the fourth positioning part 613d4 and the sixth positioning part 613n are used to position the end position of the counter 613. Therefore, one of the third positioning part 613d and the fifth positioning part 613m can be set, or both can be set. At the same time, one of the fourth positioning part 613d4 and the sixth positioning part 613n can be set, or both can be set.

[0276] Among them, the third positioning part 613d3 and the fourth positioning part 613d4 achieve the positioning of the counting element 613 by abutting against the transmission member 62 (specifically the forced push part 621), and the fifth positioning part 613m and the sixth positioning part 613n achieve the positioning of the counting element 613 by combining with the cover member 24; as Figure 35A As shown, both the fifth positioning part 613m and the sixth positioning part 613n are configured as recesses with a vertical surface and an inclined surface. The vertical surface is parallel to the rotation axis L8 and is used to limit the counter 613 from rotating in the opposite direction. The inclined surface is inclined relative to the rotation axis L8 and is used to allow the counter 613 to rotate in the forward direction. Figure 33As shown, the cover 24 is provided with a cantilever 241 similar to the abutment protrusion 275. The cantilever is provided with a protrusion (not shown) that can enter the recess. When the counter 613 is in the starting position, the protrusion enters the fifth positioning part 613m. When the counter 613 reaches the end position, the protrusion enters the sixth positioning part 613n.

[0277] Compared with Embodiment 2, in this embodiment, the action component 63 and the transmission component 62 are integrally formed, and the overall structure of the detection device 6 is simplified. When the transmission component 62 is moved, the transmission component 62 can transmit the force to the action component 63 more efficiently. Conversely to Embodiment 2, the rotation direction of the action component 63 and the transmission component 62 will be consistent. That is, when the right side 62b of the transmission component connected to the action component 63 moves towards the front 53 of the developing cartridge, the action component 63 causes the detected component 9 to move from the non-deviation position to the deviation position. When the right side 62b of the transmission component moves towards the rear 54 of the developing cartridge, the action component 63 causes the detected component 9 to move from the deviation position to the non-deviation position.

[0278] The detection process of detection device 6 is described below with reference to the accompanying drawings. To more clearly demonstrate the detection process of detection device 6, Figure 37A , Figure 37B , Figure 38A , Figure 38B , Figure 39A , Figure 39B , Figures 40A-40D as well as Figures 41A-41D Only the detection device 6 and the tested item 9 were retained.

[0279] like Figure 36A and Figure 36B As shown, when the developing cartridge is first installed in the predetermined position of the equipment and has not yet started working, the first indicator 273 is in a position opposite to the second indicator 6121. The second actuating protrusion 613f among the multiple protrusions provided in the counter 613 abuts against the third abutting part 6127. At the same time, the outer surface of the positioning protrusion 613d abuts against the forced pushing part 621. The left side 62a of the transfer member is pushed towards the rear 54 of the developing cartridge. The reset member that abuts against the transfer member 62 undergoes elastic deformation. The reaction force applied by the reset member to the transfer member 62 causes the left side 62a of the transfer member to tend to move towards the front 53 of the developing cartridge. However, the abutment between the positioning protrusion 613d and the forced pushing part 621 keeps the left side 62a of the transfer member in place. Figure 36A The position shown is 54 behind the developing chamber.

[0280] Specifically, along the rotation direction r5, the third abutment 6127 restricts the downstream of the second actuating protrusion 613f, while the forced push 621 restricts the downstream of the positioning protrusion 613d. In this way, the counting member 613 can be held in the starting position, and the transfer member 62 is also held in the position on the left side 62a of the transfer member facing the rear 54 of the developing cartridge. The detected member 9 is held in the off-position, and the installation of the developing cartridge can be detected by the equipment.

[0281] Furthermore, before the counter 613 starts working, even if the counter 613 has a tendency to rotate in the opposite direction, the third positioning part 613d3 will abut against the forced pushing part 621, or abut against the cantilever protrusion provided on the cover through the fifth positioning part 613m, and the tendency of the counter 613 to rotate in the opposite direction can be stopped.

[0282] As the driving force receiver 41 begins to rotate, the driving force input 6128 in the driving member 612 also begins to rotate after receiving the driving force from the driving force receiver 41. If the counter 613 does not require a delay, the driving force output 6122 will directly engage with the driving force receiver 612a; if the counter 613 requires a delay, the driving force output 6122 will rotate a predetermined angle, causing the actuating part 4411 to begin contacting the actuated part 612c. Figure 37A and Figure 37B As shown, the actuated part 612c drives the counter 613 to rotate around the rotation axis L8 by an angle. When the actuated part 4411 is disengaged by the actuated part 612c, the driving force output part 6122 begins to engage with the driving force receiving part 612a.

[0283] like Figure 38A and Figure 38B As shown, as the counter 613 continues to rotate, the positioning protrusion 613d disengages from the forced push 621. Under the reset force released by the reset member 67, the transmission member 62 rotates around the rotation axis L6. The left side 62a of the transmission member moves towards the front 53 of the developing cartridge, and the right side 62b of the transmission member moves towards the rear 54 of the developing cartridge. Simultaneously, the second rod 92 of the detected member returns from the deviated position to the non-deviated position. Figure 39A and Figure 39B As shown, when the first actuating protrusion 613e abuts against the forced push part 621, the left side 62a of the transmission member moves again toward the rear 54 of the developing cartridge, and the right side 62b of the transmission member moves again toward the front 53 of the developing cartridge. At the same time, the reset member 67 that abuts against the transmission member 62 undergoes elastic deformation again, and the action component 63 connected to the right side of the transmission member causes the detected member 9 to move from the non-deviation position to the deviation position.

[0284] Subsequently, the second positioning protrusion 613f abuts against the forced push part 621, and the transmission member 62 causes the detected part 9 to move again between the off-center and non-off-center positions, such as... Figure 40A and Figure 40B As shown, at the end of the detection process, after the second positioning protrusion 613f disengages from the forced push part 621, the forced push part 621 abuts against the positioning protrusion 613d under the reset force of the reset member 67. At this time, the trigger member 6126 abuts against the triggered surface 613q1. Along the radial direction of the counter member 613, the triggered member 613q is closer to the rotation axis L8 than the plurality of protrusions (613d, 613e and 613f). Therefore, when the trigger member 6126 rotates at a constant speed with the drive member 612, the result of the triggered member 613q being pushed by the trigger member 6126 is that the rotational speed (linear speed) of the counter member 613 increases. This increase in rotational speed is relative to the rotational speed generated by the counter member 613 by the drive force output part 6122 driving the drive force receiving part 613c.

[0285] Understandably, the closer the contact position between the trigger 6126 and the triggered surface 613q1 is to the rotation axis L8, the more obvious the acceleration phenomenon generated by the counter 613. Preferably, the trigger 6126 is engaged with the root of the triggered surface 613q1 (i.e., the side closer to the rotation axis L8), or in other words, engaged with... Figure 35C Along the radial direction of the counter 613, the contact position between the trigger 6126 and the triggered surface 613q1 is closer to the endpoint F, which is a point closer to the rotation axis L8 than the endpoint E.

[0286] Preferred, such as Figure 40C and Figure 40D As shown, at the end of the detection phase, the moment when the trigger 6126 contacts the triggered member 613q is later than the moment when the driving force output part 6122 disengages from the driving force receiving part 613c. For example, the moment when the trigger 6126 contacts the triggered member 613q can be the moment when the driving force output part 6122 and the driving force receiving part 613c have just disengaged, or it can be within a predetermined time after the driving force output part 6122 and the driving force receiving part 613c have disengaged.

[0287] like Figure 41A and Figure 41BAs shown, when the trigger 6126 triggers the triggered member 613q, the driving force output part 6122 is opposite to the toothed part 612b, and the counter 613 continues to rotate in the forward direction around the rotation axis L8. When the trigger 6126 and the triggered member 613q disengage, the counter 613 no longer receives driving force and remains stationary. The fourth positioning part 613d4 abuts against the forced push part 621, and the protrusion on the cover enters the sixth positioning part 613n. The counter 613 can be held in a stationary position, and the possible reverse rotation of the counter 613 is prevented. Even if the driving member 612 continues to rotate, the driving force will not be transmitted from the driving member 612 to the counter 613. The left side 62a of the transmission member is pushed and held towards the rear 54 of the developing cartridge, and the right side 62b of the transmission member is pushed and held towards the front 53 of the developing cartridge. At the same time, the action component 63 connected to the right side 62b of the transmission member forces the detected member 9 to move from the non-offset position to the offset position and hold it.

[0288] The reset of detection device 6 is described below.

[0289] As described above, after the detection device 6 completes the detection, the counter 613 will remain in a stationary position, while the drive 612 can be set to receive driving force and be in a rotating state, or it can be set to no longer receive driving force and remain stationary. When the developing cartridge stops working, the position of the drive 612 is uncertain. That is to say, the position of the second indicator 6121 on the drive 612 relative to other components is random.

[0290] When the user adds new developer to the developing cartridge, the detection device 6 needs to be reset to ensure that the developing cartridge can be recognized when it is reinstalled into the equipment. Therefore, the reset of the detection device 6 includes resetting the drive unit 612 and the counter unit 613.

[0291] The reset of the drive member 612 can be achieved simply by rotating the drive member 612 so that the second indicator 6121 is opposite to the first indicator 273 on the left end cover, but the direction of rotation of the drive member 612 does not need to be restricted; the reset of the counter member 613 can be achieved by continuing to rotate the counter member 613 in the forward direction along the rotation direction r5, so that the forced push part 621 returns to the downstream of the third positioning part 613d3. At this time, the forced push part 621 abuts against the outer surface of the third positioning part 613d3 again, and at the same time, the second actuating protrusion 613f abuts against the third abutting part 6127, and the protrusion on the cover enters the fifth positioning part 613m.

[0292] Preferably, the angle at which the transmission component 62 can rotate around the rotation axis L8 in this embodiment should be controlled within the range of 3°-45°. This allows for precise manipulation of the tested component 9 while also reducing the size of the developing cartridge in the plane of the transmission component 62's movement trajectory. More preferably, the angle is between 3.5° and 6°.

[0293] Based on the above technical concept, in some embodiments, the transmission member 62 is configured such that, along the first direction, the size of the left side 62a of the transmission member is smaller than the size of the right side 62b of the transmission member. This configuration makes the transmission member 62 form a lever that requires more effort. Therefore, when the left side 62a of the transmission member is actuated by the plurality of protrusions, the right side 62b of the transmission member can obtain a larger amount of rotation along the rotation direction of the transmission member 62, which makes it easier to meet the deviation requirements of the detected item 9, thereby making the detection results more accurate.

[0294] As described above, the rotation axis L4 of the driving member 6112 intersects the rotation axis L8 of the counting member 613. During the rotation of the driving member 612, the trigger member 6126 in the driving member triggers the triggered member 613q in the counting member 613, thereby accelerating the rotation of the counting member 613. The acceleration of the counting member 613 varies depending on the position where the trigger member 6126 triggers the triggered member 613q. The closer the trigger member 6126 is to the rotation axis L8, the greater the acceleration of the counting member 613. This requires the trigger member 6126 to protrude a larger dimension from the base 6120.

[0295] like Figure 42 As shown, along the protruding direction of the trigger 6126, the distance between the surface of the trigger 6126 and the position closest to the base 6120 on the outer circumference of the positioning post 613p is h3 = 4.81 mm. The protrusion dimension of the trigger 6126 from the base 6120 is h4. When h3 = h4, the counter 613 can obtain the maximum acceleration. However, considering the production error and assembly error of the parts, h4 is preferably 4.75 mm. According to the inventor's test, when h4 = 3.5 mm, the acceleration obtained by the counter 613 can basically meet the detection requirements of some models of developing cartridges. Therefore, h4 is preferably 3.5 mm to 4.81 mm, preferably 4.75 mm. However, in some other developing cartridges, the value of h4 can also be less than 3.5 mm. Therefore, the value of h4 can be freely selected in the range of 0.5 mm to 4.81 mm.

[0296] In the developing cartridge of this embodiment, the conductive element 26 includes a first conductive element 261 and a second conductive element 262 formed separately. Along a first direction, an movable gap is formed between the first conductive element 261 and the second conductive element 262, thereby reducing the compression of the conductive element 26 on the power output component in the imaging device and reducing the wear of the conductive element 26 and the power output component. The first conductive element 261 is formed by injection molding of conductive resin, and the second conductive element 262 is formed by bending a metal sheet. The second conductive element 262 can transmit the received power to the first conductive element 261, and at the same time, the second conductive element 262 also transmits the received power to the developer conditioning component 29.

[0297] As described above, along the third direction, the powder filling port 2a3 is located on the same side as the actuating component 63, and the powder filling port 2a3 is located below the actuating component 63. For the transmission component 62, which rotates around the rotation axis L6 intersecting the first direction, when the actuating component 63 rotates around the rotation axis L6 together with the transmission component 62 and is observed along the first direction, the movement trajectory of the actuating component 63 does not coincide with the powder filling port 2a3, or in other words, the movement trajectory of the actuating component 63 is located outside the powder filling port 2a3. At this time, no matter whether the actuating component 63 is set to swing in the left-right direction or in the front-back direction, the stopping position of the actuating component 63 will not hinder the replenishment of developer through the powder filling port 2a3. Therefore, the size design freedom of the powder filling port 2a3 will be higher. Finally, the powder filling port 2a3 is sealed by the sealing cap 2a4. Furthermore, the conductive end of the developing cartridge does not need to be provided with a right end cover 28. Along the first direction, the right end face 22 / acting component 63 / sealing cover 2a4 are all directly exposed. This design will make the right side structure of the developing cartridge simpler, not only eliminating the need for the right end cover 28, but also allowing the user to quickly replenish the developer through the powder filling port 2a3. At this time, the second forced push part 2b2 is provided on the right side of the housing 2.

[0298] like Figure 44A , Figure 44B and Figure 44C As shown, the developing cartridge also includes a protective cover 105 that is combined with the housing 2. After the developing cartridge is assembled, the developing element 31 can be effectively protected by installing the protective cover 105 onto the housing 2.

[0299] Furthermore, the developing cartridge also includes a support column 2a5 for supporting the driving force receiving member 41 and a bracket 2f for supporting the rotating shaft of the developing member 31 and the rotating shaft of the powder feeding member 32. Preferably, the support column 2a5 extends from the left end face 21 of the housing 2 in a first direction away from the developer chamber 10 (i.e., one end in the first direction); the bracket 2f is provided with a first through hole 2f1 and a second through hole 2f2 through which the rotating shaft of the developing member and the rotating shaft of the powder feeding member pass, respectively.

[0300] Along the first direction, the driving force receiver 41 is located to the left of the bracket 2f. In this embodiment, the driving force receiver 41 will generate a thrust towards the housing 2 during rotation. Preferably, the driving force receiver 41 abuts against the bracket 2f (e.g., Figure 46 As shown, the bracket 2f is made of a wear-resistant material (e.g., POM) to reduce the wear of the driving force receiver 4 during rotation. More preferably, the bracket 2f is also provided with a third through hole 2f3 for the support column 2a5 to pass through.

[0301] Furthermore, the drive force transmission assembly 4 also includes an intermediate gear 46 coupled to the drive force receiver 41, the intermediate gear 46 being used to transmit the drive force, such as... Figure 45 As shown, the intermediate gear 46 is integrally formed with the driving force receiving member 41; therefore, the intermediate gear 46 can also be considered as part of the driving force receiving member 41. A driving force transmission part 461 is formed inside the intermediate gear 46, and an insertion gap 462 is formed between the driving force transmission part 461 and the intermediate gear 46 along the radial direction of the intermediate gear 46. Figure 46 As shown, when the driving force receiving member 41 is installed, the support column 2a5 enters the insertion gap 462, and the driving force transmission part 461 is combined with the driving rod 89. The driving rod 89 is used to drive the stirring member 5, which is movably installed in the developer chamber 10. In this way, when the driving force receiving member 41 rotates, the driving rod 89 can be driven to rotate synchronously.

[0302] like Figure 44B As shown, along the first direction, the idler wheel 45 also includes a first protrusion 451 and a second protrusion 452 extending in opposite directions respectively. The first protrusion 451 engages with the support hole 276 provided on the left end cover 27, and the second protrusion 452 engages with the housing 2. Therefore, the idler wheel 45 can be easily positioned and stably supported.

[0303] In the driving force transmission assembly 4, the intermediate gear 46 is used to transmit the driving force of the driving force receiving member 41. The developing member driving gear 42 meshes with the intermediate gear 46 and drives the developing member 31 to rotate. The powder feeding member driving gear 43 meshes with the intermediate gear 46 and drives the powder feeding member 32 to rotate. The idler gear 45 meshes with the intermediate gear 46 and transmits the driving force to the stirring member gear 44. The stirring member gear 44 serves as the driving source of the driving member 612. Preferably, the intermediate gear 46, the developing member driving gear 42, and the powder feeding member driving gear 43 are connected in a driving force transmission assembly. The module of at least one of the powder drive gear 43 and idler gear 45 is smaller than the module of at least one of the stirring gear 44, the drive member 612 and the counting member 613. Therefore, the driving force of the driving force receiving member 41 can be stably transmitted to the developing member 31 and the powder feeding member 32. For the stirring gear 44, the drive member 612 and the counting member 613, as long as the driving force can be transmitted, it is sufficient. Therefore, even if the module of the stirring gear 44, the drive member 612 and the counting member 613 increases, it will not affect the detection of the detection device 6.

[0304] In this embodiment, the chip assembly 11 and the counter 613 are disposed on the same side, thus simplifying the structure of the conductive end. The chip assembly 11 includes a conductor A92, a pusher A93, a movable member A94, and a chip 7. The chip 7 is fixedly mounted on the movable member A94. The conductor A92 is used to electrically connect the chip 7 and the stylus in the imaging device. Before the developing cartridge is installed, the conductor A92 and the chip 7 are not connected. As the developing cartridge is installed, the movable member A94 is abutted, and the pusher A93 undergoes elastic deformation, thereby connecting the chip 7 and the conductor A92. When the developing cartridge reaches the predetermined position of the imaging device, the conductor A92 is connected to the stylus. Thus, the conductor A92 connects the stylus and the chip 7. When the movable member A94 is no longer abutted, the pusher A93 releases the pushing force, and the movable member A94 moves the chip 7 away from the conductor A92. The chip 7 is configured to move with the movement of the movable member A94, thus reducing the wear of the chip 7.

[0305] Along the third direction, the driving force receiver 41 / support column 2a5 / rotation axis L2 is located above the conductor A92 / chip 7. In this way, the impact of the vibration generated by the driving force receiver 41 during operation on the conductor A92 / chip 7 can be reduced. Preferably, along the third direction, the driving force receiver 41 / support column 2a5 / rotation axis L2 and the conductor A92 / chip 7 are located at the two ends of the housing 2, thereby further reducing the impact of the vibration on the conductor A92 / chip 7.

[0306] As described above, in the detection device 6, the rotation axes of the driving member 612 and the counting member 613 intersect, and the driving force is transmitted between the driving member 612 and the counting member 613 through bevel teeth. Preferably, the driving member 612 and the counting member 613 are positioned on the same base, such as... Figure 47As shown, the upper housing 2a is provided with a drive member support shaft 65 and a counter member support shaft 66 for supporting the drive member 612 and the counter member 613, respectively. The extension direction of the drive member support shaft 65 and the extension direction of the counter member support shaft 66 intersect. Therefore, the upper housing 2a is the base for supporting the drive member 612 and the counter member 613, so that the drive member 612 and the counter member 613 can be precisely coupled.

[0307] It is possible that the drive member support shaft 65 and the counter member support shaft 66 can also be simultaneously arranged in the lower housing 2b. In this case, the drive member 612 and the counter member 613 will be supported by the lower housing 2b at the same time.

[0308] Example 4

[0309] like Figures 48-52 As shown, in this embodiment, the chip assembly 11 is simplified to include only the chip 7, as... Figure 48 As shown, the housing 2 is provided with a chip holder 19 for supporting the chip 7. Specifically, along the first direction, the chip holder 19 extends from the housing 2 in a direction away from the housing 2. Similarly, along the third direction, the chip holder 19 is located below the driving force receiver 41. Correspondingly, along the third direction, the chip 7 is also located below the driving force receiver 41 / support column 2a5 / rotation axis L2. Preferably, the chip holder 19 is integrally formed with the housing 2. Optionally, the support column 2a5 is also integrally formed with the housing 2, thereby eliminating the need for the installation steps of the chip holder 19 and the support column 2a5.

[0310] In some embodiments, along the first direction, the chip holder 19 includes a first holder 191 disposed in the housing 2 and a second holder 192 disposed in the left end cover 27. The dimensions of the first holder 191 and the second holder 192 in the first direction are both smaller than the dimensions of the chip 7 in the first direction, but the sum of the dimensions of the first holder 191 and the second holder 192 in the first direction is not less than the dimensions of the chip 7 in the first direction. In this way, the chip 7 can be easily installed and removed, and the chip 7 can also be stably supported by the chip holder 19.

[0311] In some embodiments, such as Figure 4B As shown, the chip assembly 11 is mounted on the housing 2; that is, the components supporting the chip assembly 2 are disposed on the housing 2. The following description, in conjunction with... Figure 50 This structure will be further explained.

[0312] like Figure 4B and Figure 50As shown, the chip holder 19 is disposed on the housing 2. For example, the chip holder 19 and the housing 2 are fixedly connected by fasteners, or the chip holder 19 is integrally formed with the housing 2. Along the third direction, the chip holder 19 is located below the driving force transmission component 4. In this way, the chip holder 19 can not only protect at least a part of the driving force transmission component 4, but also serve as an embodiment of a positioning component. During the installation of the left end cover 27, the chip holder 19 positions the left end cover 27.

[0313] Continue as Figure 50 As shown, the chip 7 includes a substrate 71 and electrical contacts 72 disposed on the substrate 71. The electrical contacts 72 are used to establish a communication connection with an imaging device. The substrate 71 is accommodated by a receiving portion 190 disposed in the chip holder 19. This modified embodiment also provides a structure to ensure that the chip 7 is correctly installed in the receiving portion 190.

[0314] The receiving portion 190 is formed as a recessed portion formed by a surface of the chip carrier 19 recessed into the chip carrier. Therefore, at least one blocking portion / rib 193 protruding relative to the bottom surface of the recessed portion 190 will be formed around the recessed portion 190. The substrate 71 has a side 711 corresponding to the blocking portion. In practice, the substrate 71 and the bottom surface of the recessed portion 190 can be in contact or spaced apart from each other.

[0315] Taking the blocking portion 193 extending along the first direction as an example, the blocking portion 193 includes a plurality of sub-blocking portions arranged adjacent to each other in the first direction, at least two of the sub-blocking portions having different dimensions in the first direction, and in the two sub-blocking portions with different dimensions, one of the sub-blocking portions is closer to the geometric center J of the bottom surface of the recess 190 than the other sub-blocking portion. Figure 50 The diagram shows a first sub-blocking portion 19a and a second sub-blocking portion 19b. Along a first direction, the dimensions of the first sub-blocking portion 19a and the second sub-blocking portion 19b are different. The first sub-blocking portion 19a is closer to the geometric center J than the second sub-blocking portion 19b.

[0316] Side 711 corresponds to the blocking portion 193. Side 711 also includes a plurality of sub-sides arranged adjacent to each other in the first direction. At least two sub-sides have different dimensions in the first direction, and in the two sub-sides with different dimensions, one sub-side is closer to the geometric center K of the substrate 71 than the other sub-side. Figure 50The first sub-side 71a and the second sub-side 71b are shown. Along the first direction, the length of the first sub-side 71a is m1 and the length of the second sub-side 71b is m2, where m1 is not equal to m2. After the chip 7 is accommodated by the recess 190, in the direction intersecting the first direction, the first sub-side 71a is opposite to the first sub-blocking portion 19a, and the second sub-side 71b is opposite to the second sub-blocking portion 19b. In other words, when viewed along the direction intersecting the first direction, the first sub-side 71a and the first sub-blocking portion 19a at least partially coincide, the second sub-side 71b and the second sub-blocking portion 19b at least partially coincide, and the geometric center J and the geometric center K coincide.

[0317] This configuration ensures that chip 7 is correctly installed in the recess 190, preventing it from being installed in the wrong orientation.

[0318] In some embodiments, the chip holder 19 can also be formed separately from the housing 2. This structure helps to prevent the chip holder 19 from being broken during the transportation of the housing 2. On the other hand, the chip holder 19 can be installed into the housing 2 after the chip 7 is installed into the chip holder 19, which helps to reduce the difficulty of installing the chip 7.

[0319] As described above, at least a portion of the driving force transmission component 4 is located above the chip holder 19 along the vertical / third direction. That is, at least a portion of the driving force transmission component 4 coincides with the chip holder 19. Generally, the driving force transmission component 4 is configured as a gear set. To reduce the friction between the gears in the gear set, lubricant (e.g., lubricating oil) is usually applied to at least one gear. During the operation of the driving force transmission component 4, the lubricant may be thrown off by the centrifugal force generated by the rotation of the gears and adhere to the chip holder 19. Therefore, a preferred structure of the chip holder 19 is that the side of the recess 190 facing the driving force transmission component 4 (the bottom surface of the recess 190) is closed.

[0320] like Figure 50 As shown, along the vertical / third direction, the chip holder 19 is closest to the powder feeding drive 43. The side of the recess 190 opposite to the powder feeding drive 43 (the bottom surface of the recess 190) is closed. Therefore, the lubricant thrown out by the centrifugal force generated by the powder feeding drive 43 will only adhere to the side of the chip holder 19 facing the powder feeding drive 43 (the upper surface 199 of the chip holder 19), and the chip 7 located in the recess 190 will not be contaminated.

[0321] Therefore, it can be concluded that, Figure 51 and Figure 52As shown, along the vertical / third direction, the chip holder 19 has an upward-facing upper surface 199. The projection of the upper surface 199 onto a plane perpendicular to the third direction forms a first region S1, and the projection of the chip 7 / substrate 71 onto the plane perpendicular to the third direction forms a second region S2. At least a portion of the first region S1 coincides with the second region S2, or in other words, the area of ​​the first region S1 is not less than the area of ​​the second region S2. That is, when viewed along the third direction, the chip 7 / substrate 71 can be covered by the upper surface 199. As described above, this is to prevent lubricant from adhering through the upper surface 199. On chip 7, at least the area where the first region S1 and the second region S2 overlap (i.e., the second region S2) forms a complete plane. Preferably, the first region S1 is a complete plane. The complete plane means that there is no gap 198 in the corresponding area. The gap can be any one of at least one of the following: circular, square, rhomboid, and other irregular shapes. For ease of understanding, the gap 198 formed as a circle is shown in dashed lines outside the area where the first region S1 and the second region S2 overlap. According to the above inventive concept, the gap 198 cannot be formed in the area where the first region S1 and the second region S2 overlap.

[0322] It should also be noted that the upper surface 199 can be a continuous surface or multiple discontinuous surfaces. It should be understood that any surface of the chip holder 19 facing upward along the vertical or third direction can be regarded as the upper surface 199.
