Description

Technical Field

[0001] The present invention relates to the technical field of electronic imaging, in particular to a developing box, a processing box provided with the developing box, and an electronic imaging device. Background Art

[0002] Existing developer cartridges are equipped with a chip that stores pre-set information about printing consumables and is used to exchange information with electronic imaging devices. For example, the electronic imaging device can read the type of developer cartridge installed with the chip from the chip for comparison and identification. It can also write relevant information reflecting the status of the developer cartridge into the chip. The electronic imaging device can also write the usage history of the developer cartridge and / or process cartridge into the chip based on the number of prints already made by the process cartridge equipped with the developer cartridge. This allows the manufacturer to read this usage history information from the chip returned by the user. This allows for accurate inspection and component replacement during the regeneration process, improving work efficiency.

[0003] However, since the existing developer box does not have a mechanism to protect the chip or the electrical contacts thereon, the chip is directly exposed outside the developer box, making it easy for the chip or the electrical contacts thereon to be damaged or contaminated during transportation, storage and installation of the developer box. In severe cases, the information exchange between the chip and the electronic imaging device may fail, thereby shortening the service life of the developer box. Summary of the Invention

[0004] In order to solve the above problems, the main purpose of the present invention is to provide a developing box that protects the chip when it is not in use.

[0005] Another object of the present invention is to provide a process cartridge provided with the above-mentioned developing cartridge.

[0006] Another object of the present invention is to provide an electronic imaging device provided with the above-mentioned processing box.

[0007] In order to achieve the main purpose of the present invention, the present invention provides a developing box, including an end cover and a chip, wherein the end cover is provided with a accommodating position, the developing box also includes a bracket and a pushing assembly, the bracket is arranged in the accommodating position and connected to the end cover, the bracket has a working position and a recovery position, the bracket can be switched between the working position and the recovery position, the chip is mounted on the bracket, the pushing assembly includes a trigger member and an elastic member, the trigger member is slidably connected to the end cover in the axial direction of the developing roller of the developing box, the trigger member has a trigger end, the trigger end is located on the outside of the end cover, the trigger end can be triggered and force the trigger member to move toward the inside of the end cover to drive the bracket to move to the working position, so that the contact part of the chip is located at the opening of the accommodating position, the elastic member is connected between the bracket and the end cover, the elastic member can force the bracket to move to the recovery position, so that the chip is recovered into the accommodating position.

[0008] As can be seen from the above, through the design of the developing box, when the developing box is in a non-use state, the bracket can be moved to the recovery position under the action of the elastic member to store the chip in the accommodating position to protect the chip, and prevent the chip or the electrical contacts thereon from being damaged or contaminated during transportation, storage and installation, thereby ensuring reliable information exchange between the chip and the electronic imaging device, and extending the service life of the developing box; when the developing box is in use, the trigger end of the trigger member is triggered by the trigger part provided in the processing box installation cavity of the electronic imaging device or the telescopic drive head of the electronic imaging device, driving the bracket to move to the working position, so that the chip moves to the open opening of the accommodating position and is completely exposed, so that the chip can be connected to the electrical contact pins in the electronic imaging device, and the user-friendliness of the operation is increased.

[0009] A further solution is that the bracket has a matching portion that extends toward the accommodating position, the trigger member also has a driving portion that has an inclined surface that is adjacent to the matching portion, and the elastic member is connected between the matching portion and the end cover.

[0010] As can be seen from the above, the setting of the matching part makes the structure of the bracket more optimized, reasonable and compact, reduces the volume and weight of the bracket, and reduces the load on the elastic part, so that the elastic part can more reliably force the bracket to move to the recovery position, thereby optimizing the overall structure of the developing box.

[0011] A preferred solution is that a rotating shaft is provided on one side of the bracket, the rotating shaft is parallel to the axial direction, and the rotating shaft is rotatably connected to the end cover around its own rotation axis. The mating part is inclined from the bracket to the substrate of the chip and extends away from the rotating shaft. The trigger end can be triggered and force the trigger member to move toward the inside of the end cover to drive the bracket to rotate to the working position, and the elastic member can force the bracket to rotate to the recovery position.

[0012] As can be seen from the above, the bracket is connected to the end cover through a rotating shaft, so that when the developing box is in use, the triggered trigger member can drive the bracket to rotate to the working position through the mating part, so that the chip is located at the opening of the accommodating position, so that the chip is electrically connected to the electrical contact pin of the electronic imaging device; when the developing box is not in use, the bracket is rotated to the recovery position under the action of the elastic member, so that the chip is accommodated and accommodated in the accommodating position, avoiding the chip from being exposed outside the end cover, thereby protecting the chip; in addition, the rotational connection between the bracket and the end cover makes the bracket smoother when switching between the working position and the recovery position.

[0013] Another preferred solution is that a guide groove is provided in the accommodating position, and the guide groove extends along the depth direction of the accommodating position. The bracket is also provided with a guide block, and the guide block can be slidably installed in the guide groove. The trigger end can be triggered and force the trigger member to move toward the inside of the end cover to drive the bracket to slide to the working position, and the elastic member can force the bracket to slide to the recovery position.

[0014] As can be seen from the above, the bracket is connected to the guide groove in the accommodating position through the guide block, so that when the developing box is in use, the triggered trigger member can drive the bracket to slide to the working position through the matching part, so that the chip is ejected to the opening of the accommodating position, so that the chip is electrically connected to the electrical contact pin of the electronic imaging device; when the developing box is not in use, the bracket slides to the recovery position under the action of the elastic member, so that the chip is accommodated in the accommodating position, avoiding the chip from being exposed outside the end cover, thereby protecting the chip; in addition, the rotational connection between the bracket and the end cover enables the chip to be completely accommodated in the accommodating position to better protect the chip.

[0015] A further solution is that the extending direction of the matching portion is inclined to the substrate of the chip; or the extending direction of the matching portion is parallel to the depth direction.

[0016] As can be seen from the above, the position design of the matching portion can be adjusted accordingly according to the internal space of the end cover to ensure that the trigger member and the elastic member can reliably drive the bracket to slide between the working position and the recovery position.

[0017] A further solution is that a first fool-proofing portion is provided on the side of the bracket facing the chip, a second fool-proofing portion is provided on the substrate of the chip, and the first fool-proofing portion and the second fool-proofing portion are cooperatively connected.

[0018] As can be seen from the above, the design of the first fool-proofing portion and the second fool-proofing portion can avoid chip installation errors, thereby ensuring that the installed chip can exchange information with the electronic imaging device.

[0019] A further solution is that the bracket also has a snap assembly, which includes more than two claws; a locking position is formed between the two or more claws, or a locking position is formed between the two or more claws and the first anti-foolproof part; the chip is located in the locking position, and the claws are snapped onto the chip.

[0020] As can be seen from the above, the above design allows the chip and the bracket to be disassembled and assembled, and makes the disassembly and assembly between the chip and the bracket more convenient, thereby facilitating the recycling of the developer cartridge.

[0021] A further solution is that a first limiting portion is provided on the end cover and a second limiting portion is provided on the bracket, and the second limiting portion is located at the upstream end of the first limiting portion along the movement direction of the bracket from the recovery position to the working position; when the bracket is in the working position, the first limiting portion and the second limiting portion are adjacent to each other.

[0022] As can be seen from the above, the first limiting portion and the second limiting portion can prevent the bracket from moving excessively outward from the end cover, avoiding excessive squeezing and contact between the chip and the electrical contact pins of the electronic imaging device, thereby protecting the chip and the electrical contact pins and extending the service life of the developing box and the electronic imaging device.

[0023] In order to achieve another object of the present invention, the present invention provides a processing box, including a drum box, wherein the processing box also includes the above-mentioned developing box, the drum box is connected to the developing box, and the photosensitive drum of the drum box is adjacent to the developing roller.

[0024] As can be seen from the above, the processing box provided with the above-mentioned developing box can accommodate the chip in the accommodating position when the developing box is in a non-use state to protect the chip, thereby preventing the chip or the electrical contacts thereon from being damaged, contaminated by dirt, and other problems; and, when the developing box is in use, the trigger part provided in the processing box mounting cavity of the electronic imaging device or the telescopic drive head of the electronic imaging device can trigger the trigger member, so that the trigger member drives the bracket to move to the working position, and then the chip is moved to the open position of the accommodating position and is completely exposed, so that the chip can be connected to the electrical contact pins in the electronic imaging device, and the user-friendliness of the operation is increased.

[0025] In order to achieve another object of the present invention, the present invention provides an electronic imaging device, including a shell, a processing box installation cavity is provided in the shell, wherein the above-mentioned processing box is installed in the processing box installation cavity; the electronic imaging device also includes a telescopic driving head, when the developing box is installed to the designed installation position, the telescopic driving head is docked with the driving force receiving head of the developing box, and the telescopic driving head triggers the trigger end and forces the bracket to move to the working position, or a trigger part is provided in the processing box installation cavity, when the developing box is installed to the designed installation position, the trigger part triggers the trigger end and forces the bracket to move to the working position.

[0026] As can be seen from the above, the electronic imaging device provided with the above-mentioned processing box can accommodate the chip into the accommodating position when the developing box is in a non-use state to protect the chip, thereby preventing the chip or the electrical contacts thereon from being damaged, contaminated by dirt, and other problems; and, when the developing box is in use, the trigger part or the telescopic drive head can be triggered to trigger the trigger member, so that the trigger member drives the bracket to move to the working position, thereby moving the chip to the open position of the accommodating position and fully exposing it, so that the chip can be connected to the electrical contact pins in the electronic imaging device, and the user-friendliness of the operation is increased.

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0041] First embodiment of the developing cartridge

[0042] Reference Figures 1 to 3The developing box 100 includes a powder bin 1, a stirring frame, a developing roller, a scraper, a transmission wheel set, an end cover 2, a chip 3, a bracket 4 and a pushing assembly 5. The powder bin 1 has a powder storage chamber for storing carbon powder; the stirring frame is rotatably mounted on the powder bin 1 around its first rotation axis, and the stirring frame is located in the powder storage chamber. The stirring frame stirs the carbon powder in the powder storage chamber to break up the carbon powder and prevent the carbon powder from agglomerating; the developing roller is rotatably mounted on the powder bin 1 around its second rotation axis, and the developing roller is located at the powder outlet of the powder storage chamber, so that the carbon powder in the powder storage chamber is adsorbed onto the developing roller, and the first rotation axis is parallel to the second rotation axis; the scraper is mounted on the powder bin 1 and located at the powder outlet, and the blade of the scraper is adjacent to the outer peripheral surface of the developing roller to scrape the carbon powder adsorbed on the developing roller evenly to ensure that the thickness of the carbon powder layer on the developing roller is consistent; the transmission wheel group is mounted on one end of the powder bin 1, and the transmission wheel group is respectively connected to the stirring frame and the developing roller, so that the transmission wheel group can drive the stirring frame and the developing roller to rotate respectively. The transmission wheel group has a driving force receiving head 102, and the third rotation axis of the driving force receiving head 102 is parallel to the first rotation axis.

[0043] The end cap 2 is mounted at the end of the powder bin 1 and covers the drive wheel assembly to prevent external dust and debris from invading the drive wheel assembly, thereby affecting the transmission of the drive wheel assembly or causing transmission failure. A portion of the driving force receiving head 102 passes through the end cap 2, allowing the driving force receiving head 102 to connect to the driving head of the electronic imaging device. For example, in this embodiment, the driving force receiving head 102 is used to connect to the telescopic driving head 101 of the electronic imaging device.

[0044] The end cap 2 is provided with a receiving card position 21, the bracket 4 is provided in the receiving card position 21 and is connected to the end cap 2. Specifically, in combination with Figure 4 In this embodiment, a rotating shaft 41 is provided on one side of the bracket 4. The rotating shaft 41 is parallel to the axial direction of the developing roller, and the rotating shaft 41 is rotatably connected to the end cover 2 around its own rotating axis 41. The bracket 4 has a matching portion 42, and the matching portion 42 extends toward the accommodating position 21. The matching portion 42 extends from the bracket 4 to the substrate of the chip 3 and away from the rotating shaft 41. The provision of the matching portion 42 makes the structure of the bracket 4 more optimized, reasonable and compact, reduces the volume and weight of the bracket 4, and reduces the load of the pushing assembly 5, so that the pushing assembly 5 can more reliably force the bracket 4 to move to the recovery position, thereby optimizing the overall structure of the developing cartridge 100.

[0045] The carriage 4 has a working position and a retrieving position, and the carriage 4 can be switched between the working position and the retrieving position. A chip 3 is mounted on the carriage 4. The chip 3 stores pre-set information about printing consumables and is used to electrically connect to the electrical contact pins 103 of the electronic imaging device to enable information exchange between the chip 3 and the electronic imaging device.

[0046] Preferably, a first foolproofing portion 31 is provided on the surface of the bracket 4 facing the chip 3, and a second foolproofing portion 43 is provided on the substrate of the chip 3. When the chip 3 is mounted on the bracket 4, the first foolproofing portion 31 and the second foolproofing portion 43 are engaged and connected. The design of the first foolproofing portion 31 and the second foolproofing portion 43 can prevent chip 3 from being installed incorrectly, thereby ensuring that the installed chip 3 can normally interact with the electronic imaging device.

[0047] In addition, the bracket 4 has a snap assembly 44, which includes two or more claws 441. For example, in the present embodiment, the number of the claws 441 is two, and a locking position is formed between the two claws 441 and the first anti-foolproof portion 31. When the chip 3 is mounted on the bracket 4, the chip 3 is located in the locking position, and the claws 441 are snapped onto the chip 3. By providing the snap assembly 44 on the bracket 4, the chip 3 and the bracket 4 can be disassembled and assembled, and the disassembly and assembly between the chip 3 and the bracket 4 is made more convenient, thereby facilitating the regeneration process of the developer cartridge 100. Of course, in other embodiments, the number of the claws 441 may be three or more, and a locking position may be formed between the three or more claws 441, or a locking position may be formed between the three or more claws 441 and the first anti-foolproof portion 31.

[0048] Combine Figures 5 to 7 The push assembly 5 includes a trigger member 51 and an elastic member 52. The trigger member 51 is slidably connected to the end cover 2 in the axial direction of the developing roller. The trigger member 51 has a trigger end 511 and a driving portion 512. In the axial direction of the developing roller, the trigger end 511 and the driving portion 512 are respectively located on either side of the end cover 2. Specifically, the trigger end 511 is located on the outer side of the end cover 2, and the driving portion 512 is located on the inner side of the end cover 2. The driving portion 512 has an inclined surface 5121, which is used to abut the mating portion 42 of the bracket 4 to drive the bracket 4 to move toward the working position. The provision of the inclined surface 5121 enables the trigger member 51 to more smoothly push the bracket 4 to rotate relative to the end cover 2. Preferably, a third limiting portion 23 is provided on the inner side of the end cover 2 to limit the driving portion 512, so as to prevent the trigger member 51 from rotating relative to the end cover 2, causing the driving portion 512 to disengage from the mating portion 42, thereby causing the push assembly 5 to fail.

[0049] The elastic member 52 is connected between the mating portion 42 and the end cap 2. Preferably, a slot is provided on the inner side of the end cap 2, and one end of the elastic member 52 is engaged within the slot. The elastic member 52 is a compression spring, and the elastic member 52 and the rotating shaft 41 are located on either side of the mating portion 42. Of course, in other embodiments, the elastic member 52 may also be a tension spring. When the elastic member 52 is a tension spring, the elastic member 52 and the rotating shaft 41 are located on the same side of the mating portion 42. Furthermore, the main body of the bracket 4 is hollowed out, thereby effectively reducing the mass of the bracket 4 and enabling the elastic member 52 to better drive the bracket to move to the retracted position.

[0050] In this embodiment, when the developing cartridge 100 is installed to the designed installation position, the telescopic driving head 101 of the electronic imaging device gradually moves toward the trigger end 511 of the trigger member 51 and presses the trigger end 511, so that the trigger member 51 is forced to move toward the inner side of the end cover 2 along the first direction X1. During the movement of the trigger member 51 toward the inner side of the end cover 2, the driving portion 512 pushes the matching portion 42 of the bracket 4 through the inclined surface 5121, so that the bracket 4 gradually rotates toward the opening of the accommodating position 21 of the end cover 2 along the first rotation direction R1 (that is, gradually rotates toward the working position); when the trigger member 51 drives the bracket 4 to move to the working position (such as Figure 6 and Figure 7 As shown), the bracket 4 and the contact portion of the chip 3 thereon are located at the accommodating position 21, so that the contact portion of the chip 3 is completely exposed from the end cover 2 and is electrically connected to the electrical contact pin 103 of the electronic imaging device, thereby enabling the chip 3 to exchange information with the electronic imaging device.

[0051] Preferably, a first stopper 22 is provided on the end cap 2, and a second stopper 45 is provided on the bracket 4. The second stopper 45 is located upstream of the first stopper 22 as the bracket 4 moves from the retracted position to the operating position. When the bracket 4 is in the operating position, the first stopper 22 and the second stopper 45 abut against each other. The first stopper 22 and the second stopper 45 prevent the bracket 4 from moving excessively outward from the end cap 2, thus preventing excessive compression and contact between the chip 3 and the electrical contact pins 103 of the electronic imaging device. This protects the chip 3 and the electrical contact pins 103, thereby extending the service life of the developing cartridge 100 and the electronic imaging device.

[0052] When the developing cartridge 100 needs to be withdrawn from the designed installation position, the telescopic driving head 101 of the electronic imaging device gradually moves away from the trigger end 511 of the trigger member 51. During this process, the bracket 4 gradually rotates toward the receiving position 21 of the end cover 2 along the second rotation direction R2 under the action of the elastic member 5 (that is, gradually rotates toward the recovery position). At the same time, the trigger member 51 moves toward the outside of the end cover 2 along the second direction X2 under the action of the driving part 512 and the matching part 42. When the bracket 4 moves to the recovery position under the force of the elastic member 52 (that is, when the trigger end 511 of the trigger member 51 is not triggered, as shown in FIG. Figure 2 and Figure 3 As shown, the bracket 4 and the chip 3 thereon are retracted into the receiving position 21, thereby protecting the chip 3 and preventing damage to the chip 3 or its electrical contacts, contamination, and other problems. The first direction X1 is opposite to the second direction X2, and the first direction X1 is parallel to the axial direction of the developing roller; the first rotational direction R1 is opposite to the second rotational direction R2.

[0053] In summary, it can be seen that this embodiment designs the developing box so that when the developing box is in use, the triggered trigger member can drive the bracket to rotate to the working position through the mating part, so that the chip is located at the open opening of the accommodating position, so that the chip is electrically connected to the electrical contact pin of the electronic imaging device, and at the same time improves the user-friendliness of the operation; when the developing box is not in use, the bracket is rotated to the recovery position under the action of the elastic member, so that the chip is accommodated and accommodated in the accommodating position, avoiding the chip from being exposed outside the end cover, thereby protecting the chip; in addition, the rotational connection between the bracket and the end cover makes the bracket smoother when switching between the working position and the recovery position.

[0054] Second embodiment of the developing cartridge

[0055] Reference Figures 8 to 12 The difference between this embodiment and the first embodiment of the developing cartridge mainly lies in the partial structure of the end cover 6, the partial structure of the bracket 8, the connection method between the bracket 8 and the end cover 6, etc. The following is an explanation of the differences. Specifically, in this embodiment:

[0056] The bracket 8 has eliminated the rotating shaft and is provided with a guide block 81. The end cap 6 is provided with a guide groove 611 within the receiving position 61. The number of guide grooves 611 is equal to the number of guide blocks 81, and the number of guide grooves 611 is preferably two or more. In this embodiment, there are two guide grooves 611, which are respectively provided on two oppositely disposed groove walls of the receiving position 61. Along the axial projection of the developing roller, the projections of the two guide grooves 611 are located on both sides of the projection of the trigger end 911. A guide block 81 is slidably mounted within a corresponding guide groove 611, allowing the bracket 8 to slide along the guide groove 611. The guide groove 611 extends along the depth direction of the receiving position 61; the depth direction is perpendicular to the axial direction of the developing roller.

[0057] The mating portion 82 on the bracket 8 extends in an oblique direction relative to the substrate of the chip 7. The elastic member 92 is a compression spring, with both ends of the elastic member 92 respectively abutting between the mating portion 82 and the end cap 6. The elastic member 92 and the driving portion 912 of the trigger member 91 are located on opposite sides of the mating portion 82. Furthermore, the inclined surface 9121 of the driving portion 912 of the trigger member 91 abuts the mating portion 82, allowing the trigger member 91 to drive the bracket 8 in the depth direction via the inclined surface 9121. Alternatively, the mating portion 82 of the bracket 8 can force the trigger member 91 to move outward from the end cap 6 in the axial direction of the developer roller via the inclined surface 9121.

[0058] When the developing cartridge is installed to the designed installation position, the telescopic driving head 104 of the electronic imaging device gradually moves toward the trigger end 911 of the trigger member 91 and presses the trigger end 911, so that the trigger member 91 is forced to move toward the inner side of the end cover 6 along the third direction X3. During the movement of the trigger member 91 toward the inner side of the end cover 6, the driving portion 912 pushes the matching portion 82 of the bracket 8 through the inclined surface 9121, so that the bracket 8 gradually slides toward the opening of the accommodating position 61 of the end cover 6 along the fifth direction Z1 (that is, gradually slides toward the working position); when the trigger member 91 drives the bracket 8 to move to the working position (such as Figure 11 and Figure 12 As shown), the contact portion of the bracket 8 and the chip 7 thereon is located at the accommodating position 61, so that the contact portion of the chip 7 is completely exposed from the end cover 6 and is electrically connected to the electrical contact pin 105 of the electronic imaging device, thereby enabling the chip 7 to exchange information with the electronic imaging device.

[0059] When the developing cartridge needs to be withdrawn from the designed installation position, the telescopic driving head 104 of the electronic imaging device gradually moves away from the trigger end 911 of the trigger member 91. During this process, the bracket 8 gradually slides into the receiving position 61 of the end cover 6 along the sixth direction Z2 under the action of the elastic member 92 (i.e., gradually slides toward the recovery position). At the same time, the trigger member 91 moves toward the outside of the end cover 6 along the fourth direction X4 under the action of the driving part 912 and the matching part 82. When the bracket 8 moves to the recovery position under the force of the elastic member 92 (i.e., when the trigger end 911 of the trigger member 91 is not triggered, as shown in FIG. Figure 8 and Figure 9 As shown, the bracket 8 and the chip 7 thereon are completely retracted into the receiving position 61, thereby protecting the chip 7 and preventing damage to the chip 7 or its electrical contacts, as well as contamination. The third direction X3 is opposite to the fourth direction X4, and both are parallel to the axial direction of the developing roller. The fifth direction Z1 is opposite to the sixth direction Z2, and both are parallel to the depth direction.

[0060] In summary, it can be seen that this embodiment designs the developing box so that when the developing box is in use, the triggered trigger member can drive the bracket to slide to the working position through the mating part, so that the chip is ejected to the opening of the accommodating position, so that the chip is electrically connected to the electrical contact pins of the electronic imaging device, and at the same time the user-friendliness of the operation is improved; when the developing box is not in use, the bracket slides to the recovery position under the action of the elastic member, so that the chip is accommodated in the accommodating position, avoiding the chip from being exposed outside the end cover, thereby protecting the chip; in addition, the rotational connection between the bracket and the end cover enables the chip to be completely accommodated in the accommodating position to better protect the chip.

[0061] Third embodiment of the developing cartridge

[0062] Reference Figure 13 The difference between this embodiment and the second embodiment of the developing cartridge lies in the structure of the matching portion of the bracket. Specifically, in this embodiment:

[0063] The mating portion 931 of the bracket 93 extends along the depth direction of the receiving latch 941 of the end cap 94, toward the inside of the receiving latch 941. A supporting portion 9311 is provided at the protruding end of the mating portion 9311, which is provided with a second retaining groove 9312. A third retaining groove 942 is provided on the inner side of the end cap 94, and the second and third retaining grooves 9312 and 942 are distributed along the depth direction of the receiving latch 941. The axial direction of the elastic member 95 is parallel to the depth direction of the receiving latch 941, and the ends of the elastic member 95 are respectively engaged in the second and third retaining grooves 9312 and 942, and respectively abut against the end cap 94 and the supporting portion 9311.

[0064] In summary, the above design enables the elastic member to better drive the bracket to move toward the retracted position, thereby preventing the bracket from getting stuck during the movement toward the retracted position.

[0065] Processing box embodiment

[0066] The process cartridge includes a drum cartridge and a developer cartridge, wherein the developer cartridge is any of the developer cartridges described in the first to third embodiments. The drum cartridge includes a drum frame and a photosensitive drum, the photosensitive drum being rotatably mounted on the drum frame about a fourth rotational axis parallel to the second rotational axis. The drum frame is detachably connected to the developer cartridge, and when the developer cartridge is mounted on the drum frame, the photosensitive drum abuts the developer roller of the developer cartridge.

[0067] The processing box provided with the above-mentioned developing box can accommodate the chip in the accommodating position when the developing box is not in use to protect the chip, thereby preventing the chip or the electrical contacts thereon from being damaged, contaminated by dirt, and other problems; and, when the developing box is in use, the trigger part provided in the processing box installation cavity of the electronic imaging device or the telescopic driving head of the electronic imaging device can trigger the trigger member, so that the trigger member drives the bracket to move to the working position, and then the chip is moved to the open position of the accommodating position and is completely exposed, so that the chip can be connected to the electrical contact pins in the electronic imaging device, thereby increasing the user-friendliness of the operation.

[0068] First embodiment of electronic imaging device

[0069] The electronic imaging device includes a housing and a process cartridge, wherein the process cartridge is the process cartridge described in the above-mentioned process cartridge embodiment. A process cartridge mounting cavity is provided within the housing, and the process cartridge is mounted within the process cartridge mounting cavity. The electronic imaging device also includes a telescopic drive head. When the developer cartridge is installed in the designed mounting position, the telescopic drive head docks with the driving force receiving head of the developer cartridge, and the telescopic drive head triggers a trigger end and forces a bracket to move to a working position. When the developer cartridge is installed in the designed mounting position, the trigger portion triggers the trigger end and forces the bracket to move to the working position. The process of the telescopic drive head triggering the trigger end of the trigger member can be found in the description of the first or second embodiment of the developer cartridge.

[0070] It can be seen that the electronic imaging device provided with the above-mentioned processing box can accommodate the chip into the accommodating position when the developing box is in a non-use state to protect the chip, thereby preventing the chip or the electrical contacts thereon from being damaged, contaminated by dirt, and other problems; and, when the developing box is in use, it can also trigger the trigger part through the trigger part or the telescopic drive head, so that the trigger part drives the bracket to move to the working position, and then move the chip to the open position of the accommodating position and fully expose it, so that the chip can be connected to the electrical contact pins in the electronic imaging device, and the user-friendliness of the operation is increased.

[0071] Second embodiment of electronic imaging device

[0072] The difference between this embodiment and the first embodiment of the electronic imaging device is that: in this embodiment, a fixed driving head is provided instead of a telescopic driving head in the electronic imaging device, and a trigger portion is provided in the processing box installation cavity of the electronic imaging device.

[0073] When the developing box is gradually installed to the designed installation position, the trigger part triggers the trigger end of the trigger member, so that the trigger member is forced to move toward the inside of the end cover. During the movement of the trigger member toward the inside of the end cover, the driving part pushes the matching part of the bracket through the inclined surface, so that the bracket gradually moves toward the opening of the accommodating position of the end cover (such as rotating or sliding); when the developing box is installed to the designed installation position, the trigger part drives the bracket to move to the working position. At this time, the contact part of the bracket and the chip thereon is located at the accommodating position, so that the contact part of the chip is completely exposed from the end cover and electrically connected to the electrical contact pin of the electronic imaging device, so that the chip and the electronic imaging device can exchange information.

[0074] When the developing box gradually withdraws from the designed installation position, the matching part of the bracket gradually moves toward the recovery position (such as rotating or sliding) under the action of the elastic part, and at the same time, the trigger part gradually moves toward the outside of the end cover under the action of the matching part of the bracket; when the bracket moves to the recovery position, the bracket and the chip on it are completely retracted into the accommodating position to protect the chip, thereby preventing the chip or the electrical contacts on it from being damaged, contaminated, and other problems.

[0075] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
