Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing imaging technology, and in particular to a storage cartridge and a processing device. BACKGROUND

[0002] The cartridge storing developer is an important component in electronic imaging equipment, which consumes the developer inside with the continuous imaging process, and needs to be replaced to continue the imaging process when the developer is consumed. The current electronic imaging equipment has various models, and if an inappropriate cartridge is selected, it will affect the entire imaging work, so the electronic imaging equipment is provided with a new product detection unit to detect the newly installed cartridge to determine whether it is suitable and to obtain the cartridge capacity and other related information.

[0003] In the prior art, a detected structure capable of being detected by the detection unit is provided on the cartridge, which is usually designed as a counting gear. The cartridge is provided with a coupling driven by a driving component on the equipment, which is used to drive the rotation of the developing roller, the powder feeding roller, the stirring frame and the counting gear. However, the counting gear has a feature that the detection stroke only works when the cartridge is initially operated. After the detection stroke is completed, the detection part on the counting gear will not be detected by the detection unit again, but the gear set and other components for driving the counting gear continue to rotate, which lengthens the length of the transmission chain of the components in the cartridge, and is also easy to interfere with the spring and other structures on the counting gear, thereby affecting the rotation of other components such as the developing roller, the powder feeding roller and the stirring frame, and bringing unnecessary interference and influence to the overall timing control of the equipment.

[0028] The technical solutions of the present application will be described in detail below with reference to the drawings and specific embodiments.

[0029] The embodiments of the present application provide an electronic imaging device, referring to Figure 1, including a device body 1 and a paper box 11, a pickup assembly 12, a conveying assembly 13, a transfer assembly 14, a processing device 15, a scanning assembly 16, a fixing assembly 17 and a paper discharge assembly 18 arranged in the device body 1, the device body 1 is provided with a paper conveying path, the paper box 11 is stacked with paper for printing, the pickup assembly 12 includes a pickup roller, the pickup roller is in contact with the stacked paper and sends the paper into the paper conveying path, the conveying assembly 13 includes a correction roller and a paper feed roller, the correction roller is used to correct the position of the paper in the paper conveying path, and the paper feed roller is used to transmit the paper in the paper conveying path, the processing device 15 forms an image composed of toner inside and transfers the image to the transfer assembly 14, the transfer assembly 14 transfers the image in the paper conveying path, and after the paper obtains the image, the paper is further conveyed to the fixing assembly 17, the fixing assembly 17 fixes the image on the surface of the paper by heating, and the paper after printing is finally discharged to the outside of the device body 1 by the paper discharge assembly 18.

[0030] The scanning assembly 16 includes a laser emitting unit and an optical member for deflecting the laser emitted by the laser emitting unit, the optical member can be composed of a plurality of optical components, and the laser is deflected to the processing device 15 for the imaging process of the processing device 15. Figure 2 The processing device 15 includes a drum 100, which has a photosensitive surface containing on it, and the laser is deflected to the photosensitive surface to form an electrostatic latent image, and then the toner forms an image by using the electrostatic latent image.

[0031] The processing device 15 includes a drum 100, which has a photosensitive surface containing on it, and the laser is deflected to the photosensitive surface to form an electrostatic latent image, and then the toner forms an image by using the electrostatic latent image. Figures 2 to 9 The processing device 15 includes a drum 100, which has a photosensitive surface containing on it, and the laser is deflected to the photosensitive surface to form an electrostatic latent image, and then the toner forms an image by using the electrostatic latent image. Figure 5 The processing device 15 includes a drum 100, which has a photosensitive surface containing on it, and the laser is deflected to the photosensitive surface to form an electrostatic latent image, and then the toner forms an image by using the electrostatic latent image. Figure 7The first axis line extending in the direction U) rotates, the storage box comprises a box body 200 and a developing roller 300, the box body 200 has a storage cavity 210 for accommodating the developer and a developer outlet 220 communicating with the storage cavity 210, and the developing roller 300 is arranged at the developer outlet 220 to supply the developer to the drum 100. In the embodiment, the developing roller 300 is rotationally connected to the box body 200 and can rotate around the second axis line extending in the first direction, so that when the developing roller 300 is close to the drum 100 to supply the developer during the cooperation of the storage box and the photosensitive member, the roller surface of the developing roller 300 is parallel to the drum surface of the drum 100, so that the developer supplied to the drum 100 is uniform. It should be noted that the storage box and the photosensitive member can be arranged as an integral structure or as a split structure. When the storage box and the photosensitive member are arranged as a split structure, since the drum 100 is a component with a relatively longer service life, after the developer in the storage cavity 210 is used up, only the new storage box needs to be replaced or the developer in the storage box needs to be supplemented, so only the storage box needs to be disassembled and replaced, recycling can be realized. Of course, whether it is an integral structure or a split structure, it is within the scope of the embodiment of the present application.

[0032] The storage box is provided with a shaft coupling component 400, the shaft coupling component 400 comprises a shaft coupling driving part 410, the shaft coupling driving part 410 can be engaged with a driving part in the equipment body to receive a driving force from the driving part, and the developing roller 300 rotates around the second axis line under the driving force received by the shaft coupling driving part 410. Specifically, the shaft coupling driving part 410 is arranged as a driving gear, which can rotate around a fourth axis line extending in the first direction, and the storage box is provided with a driving gear set, the driving gear set is engaged with the shaft coupling driving part 410, the shaft coupling driving part 410 performs a rotating motion after receiving the external driving force to drive the driving gear set to rotate by the engagement of the gear part, and the driving gear set comprises a first gear 420 arranged at the end of the developing roller 300 to drive the developing roller 300 to rotate, thereby realizing the transmission of the external driving force to the storage box through the shaft coupling component 400 when the processing device is assembled in the equipment body. In the embodiment, the shaft coupling driving part 410 comprises a driving gear part engaged with the driving gear set and a shaft connecting part 411 arranged axially outside the driving gear part in the first direction, and the shaft connecting part 411 is provided with at least one engagement interval, and the driving part on the equipment body has a plug-in part capable of being inserted into the engagement interval, so that the shaft coupling driving part 410 rotates around the third axis line. Of course, other shaft connection structures can also be used, which are not limited in particular.

[0033] Further, the storage box further comprises a stirring frame 500, which is arranged in the cavity 210 and has a stirring shaft rotatably connected with the box body 200, and the stirring shaft has stirring blades (not shown in the figure) arranged thereon. When the stirring frame 500 performs a rotating action, the stirring blades stir the developer in the cavity 210 and push the developer towards the developer outlet 220. The stirring blades can be flexible blades made of flexible material, or can be a plurality of stirring blades arranged along the axis direction of the stirring shaft and arranged obliquely, see Figure 6 The stirring shaft rotates in the cavity 210 about a third axis extending in the first direction, so as to uniformly transport the developer to the developer outlet 220. In addition, the storage box further comprises a supply roller 600, and a powder conveying channel 230 is arranged between the developer outlet 220 and the cavity 210. The supply roller 600 is arranged in the powder conveying channel 230 and is close to or in contact with the developing roller 300, and can rotate about a fifth axis extending in the first direction, so as to push the developer pushed by the stirring frame 500 to the surface of the developing roller 300 and be carried by the surface of the developing roller 300. Therefore, the conveying track of the developer in the storage box is that the stirring frame 500 transports the developer from the stored cavity 210 to the powder conveying channel 230, the supply roller 600 transports the developer in the powder conveying channel 230 to the surface of the developing roller 300, and the developing roller 300 further transports the developer away from the developer outlet 220 and to the surface of the photosensitive drum 100 to form an image on the surface of the photosensitive drum 100.

[0034] In the prior art, in order to realize the acquisition of the information of the storage box by the electronic imaging device, a counting gear is arranged on the storage box, the counting gear is driven by being combined with the shaft coupling part 400, and then corresponding detection information is sent out. For example, in the existing developing box, a transmission gear set is arranged on the developing box, the transmission gear set is engaged with the shaft coupling driving part 410 to transmit power to the developing roller 300, the supply roller 600, the stirring frame 500 and the counting gear. Since the detection information on the counting gear is only needed when the developing box is stored and installed, the counting gear will be disconnected from the transmission gear set after rotating through a corresponding angle range. However, since the space at the end of the developing box is very crowded, and in order to avoid affecting the remaining parts such as the developing roller 300, the supply roller 600 or the stirring frame 500, etc. during the design process, an additional gear is arranged to engage with the shaft coupling driving part 410 to transmit power to the counting gear. This results in that the end of the developing box is more crowded, and the gears may affect each other, which leads to a decrease in the transmission accuracy of the entire transmission chain, and undoubtedly is not conducive to the miniaturization trend of the existing equipment.

[0035] To solve the above problems, there is also a developing box in the prior art, which sets the counting gear at the other end of the developing box different from the transmission gear set. In this structure, the counting gear drives the counting gear through the gear connected to the end of the developing roller 300, the supply roller 600 or the stirring frame 500 to realize the transmission of detection information, but such a setting will lengthen the entire transmission chain, especially increase the driving load of the corresponding intermediate parts such as the developing roller 300, the supply roller 600 or the stirring frame 500, which is easy to interfere with the rotation process of the intermediate parts. In the case that the counting gear is disconnected after completing the transmission of detection information, the gear connected to the counting gear will also rotate with the intermediate parts, which may affect the accurate control of the intermediate parts, cause the loss of dynamic balance of the intermediate parts, and the counting gear may also affect the rotation of the gear in the disconnected state, further affecting the developer conveying process, which may affect the power transmission of the shaft connecting part 400. Moreover, the counting gear at the end of the long transmission chain may have a large transmission error when detecting information, which affects the recognition of the new installed developing box by the equipment body.

[0036] Therefore, in view of the above defects, the embodiments of the present application continue to refer to Figures 2 to 9 The storage box further comprises a transmission part 700 and a detected part 800, both of which are arranged on the box body 200 of the storage box. The transmission part 700 comprises a power receiving part 710, which comprises a first part 711 and a second part 712. The first part 711 can receive the rotating force from the drum 100, and when the drum 100 rotates, the first part 711 can rotate with the drum 100. The second part 712 is connected with the first part 711 to perform a corresponding first motion, which can be a linear motion, a rotating motion or a curve motion along a corresponding track, etc., all within the scope of the present application. The detected part 800 comprises a detected part 810, which is provided with at least one detection part 811. The detection part 811 can be detected by a detection structure on the equipment body to transmit detection information. The detection structure can be implemented as a swinging detection rod, a photoelectric detection sensor or other detection part 811 components, without too much limitation. The detected part 810 can execute a corresponding second motion with the first motion of the second part 712 in a direct connection or indirect cooperation manner, so that the detection part 811 moves in the active range containing the detection position, and when the detection part 811 is in the detection position, it can trigger the corresponding detection structure on the equipment body to be sensed.

[0037] The embodiment cuts the transmission part 700 of the linkage detected member 810 and the shaft part 400 of the linkage storage box inner developer transmission part, so that the transmission part 700 receives the transmission force from the drum 100. Since the drum 100 is directly connected to the driving structure in the device body on the photosensitive member, the transmission is stable and not easily affected by external structures. When the transmission part 700 is connected to the drum 100, stable driving force can be received, accurate transmission of detection information is achieved, and the structure separates the detected member 800 from the transmission chain of the linkage part for developer transportation on the storage box, avoiding the transmission influence on the developer roller 300, the supply roller 600, the stirring frame 500, and other related parts, so that the developer roller 300 and other parts in the transmission chain in the box are no longer affected by the timing of the connection structure of the detected member 800.

[0038] In a specific embodiment, referring to Figure 3 The detected member 810 is a detection gear that can rotate around a sixth axis extending in the first direction. The detection gear is provided with a detection protrusion as a detection part 811. The detection protrusion is arranged on the end surface of the detection gear away from the box body 200 along the first axis and protrudes in the direction away from the box body 200 to be exposed on the outer side surface of the box body 200. When the storage box is assembled with the processing device in the device body, the second movement of the detected member 810 performed by the first movement is a rotational movement around the sixth axis, and the activity range of the detection protrusion is a revolution movement around the sixth axis with the movement of the detected member 810. The detection protrusion has at least an initial position and a detection position in this revolution movement. When the storage box is applied as a new storage box to replace in the device body to be recognized by the device body, the detection protrusion is in the initial position, and moves to the detection position with the movement of the detected member 810, triggering the detection structure to transmit the detection information. The detection information can be determined according to the triggering time or the triggering times of the detection protrusion. For example, in the activity range of the revolution movement, the larger the angle of the detection protrusion relative to the sixth axis, the longer the time of staying in the detection position, so that the triggering time can be controlled. For another example, the detection protrusion is arranged as multiple on the detected member 810. When the detected member 810 rotates one revolution around the sixth axis, the multiple detection protrusions can trigger the corresponding number of triggering times of the detection protrusions. Based on this, the corresponding detection information of the related signal can be correspondingly limited, and the related information of the replaced storage box can be known according to the obtained detection information.

[0039] In another specific embodiment, referring to Figure 7 and Figure 8 The detected member 810 is a detection gear that can rotate around a sixth axis extending in the first direction. The detection gear is provided with a detection protrusion as a detection part 811. The detection protrusion is arranged on the end surface of the detection gear away from the box body 200 along the first axis and protrudes in the direction away from the box body 200 to be exposed on the outer side surface of the box body 200. When the storage box is assembled with the processing device in the device body, the second movement of the detected member 810 performed by the first movement is a rotational movement around the sixth axis, and the activity range of the detection protrusion is a revolution movement around the sixth axis with the movement of the detected member 810. The detection protrusion has at least an initial position and a detection position in this revolution movement. When the storage box is applied as a new storage box to replace in the device body to be recognized by the device body, the detection protrusion is in the initial position, and moves to the detection position with the movement of the detected member 810, triggering the detection structure to transmit the detection information. The detection information can be determined according to the triggering time or the triggering times of the detection protrusion. For example, in the activity range of the revolution movement, the larger the angle of the detection protrusion relative to the sixth axis, the longer the time of staying in the detection position, so that the triggering time can be controlled. For another example, the detection protrusion is arranged as multiple on the detected member 810. When the detected member 810 rotates one revolution around the sixth axis, the multiple detection protrusions can trigger the corresponding number of triggering times of the detection protrusions. Based on this, the corresponding detection information of the related signal can be correspondingly limited, and the related information of the replaced storage box can be known according to the obtained detection information. Figure 6a detection gear rotating along a seventh axis extending in a third direction K intersecting the first direction, the third direction being perpendicular to the first direction in this embodiment, the detection gear being provided with a detection protrusion as the detection portion 811, the detection protrusion being provided on an end surface of the detection gear facing away from the cartridge 200 along the seventh axis and protruding in a direction away from the cartridge 200 to be exposed on an outer side surface of the cartridge 200, when the storage cartridge is assembled in the device body together with the processing device, the second movement of the detected member 810 performed by the first movement is a rotational movement around the seventh axis, and the active range of the detection protrusion is a revolution movement around the seventh axis performed by the detected member 810.

[0040] In addition to the above-described structure corresponding to the detected member 810, other detected structures in the prior art can also be used, and will not be described in detail again.

[0041] In one embodiment, referring to Figure 9 , the first part 711 includes an action portion 711a that can be in contact with the drum 100, and when the action portion 711a is in contact with the drum 100, the action portion 711a can receive a driving force from the drum 100, and the second part 712 includes a connecting portion 712a connected to the first part 711, and the connecting portion 712a is used to transmit the driving force received by the action portion 711a to make the second part 712 perform the first movement. Wherein, the power receiving member 710 has at least an initial state, which is the position of the power receiving member 710 when the storage cartridge needs to be detected by the structure recognition as a new storage cartridge, and in the initial state, the action portion 711a maintains contact with the drum 100, so that when the drum 100 performs a rotational movement around the first axis under the driving of the driving structure in the device body, the action portion 711a can perform a rotational movement relative to the axis.

[0042] In addition, the first part 711 can also receive the driving force of the drum 100 through a non-contact method such as magnetic attraction, which can achieve the same effect and is within the scope of the present application, and will not be described in detail again.

[0043] Specifically, in an embodiment, the acting portion 711a can be arranged to keep contact with the surface of the drum 100 when the drum 100 rotates by a specified angle, at this time, the rotating force of the drum 100 can be transmitted to the second portion 712, when the acting portion 711a is separated from the surface of the drum 100, the first portion 711 no longer receives the driving force of the drum 100, at this time, the second portion 712 stops the first movement. Thus, this embodiment is applied in the detection stroke of the detected component 800, when the acting portion 711a keeps contact with the surface of the drum 100, the second portion 712 drives the detected member 810 to perform the second movement, during the second movement, the detection portion 811 transmits the detection information to the detection structure, when the corresponding portion is separated, the transmission of the detection information of the detection portion 811 has been completed, the acting portion 711a is separated from the contact, at this time, it will not affect the rotating process of the drum 100, thus, the stable rotation of the drum 100 can also be ensured.

[0044] In another embodiment, the acting portion 711a can be arranged to keep contact with the surface of the drum 100 at all times, when the storage box cooperates with the photosensitive member, the rotating movement of the drum 100 always acts on the acting portion 711a, so that the first portion 711 directly receives the driving force from the drum 100, and the driving force is transmitted from the second portion 712 to the detected member 810, so that the detected member 810 can effectively perform the second movement to ensure the transmission of the detection information.

[0045] For example, referring to Figure 3 , when the acting portion 711a keeps contact with the drum 100, the first portion 711 rotates around the eighth axis extending in the first direction, so that the eighth axis is parallel to the first axis, and the distance between them is always consistent, at this time, the acting portion 711a is arranged on the side of the first portion 711 away from the eighth axis and in contact with the first portion 711, when the drum 100 performs the rotating movement, the first portion 711 rotates around the eighth axis under the action of the acting portion 711a, and further transmits the driving force to the second portion 712. In this embodiment, the first movement is around the ninth axis extending in the first direction, when the first portion 711 rotates, the second portion 712 is driven to rotate by the connecting portion 712a. Rotating the first portion 711 to drive the second portion 712 to operate can reduce the precision error caused by receiving the driving force.

[0046] Specifically, the first portion 711 and the second portion 712 are two portions arranged coaxially, that is, the eighth axis coincides with the ninth axis, when the eighth axis and the ninth axis are different axes, the connecting portion 712a can be arranged as a meshing tooth portion, a friction portion, a synchronous belt or the like structure, all of which can realize the transmission of the driving force between the first portion 711 and the second portion 712.

[0047] Further, the eighth axis and the ninth axis are coincident with the second axis, and the developing roller 300 has a roller end 310 rotatably arranged on the housing and extending along the first direction, and the power receiving member 710 is arranged on the roller end 310 and rotatable relative to the roller end 310. In this structure, the first part 711 and the second part 712 are capable of rotating about the second axis, and the distance between the rotation axis of each part and the surface of the drum 100 is consistent with the distance between the second axis of the developing roller 300 and the surface of the drum 100. For reference, see Figure 2 The photosensitive member includes a housing 900, which includes a housing body 910 and a support frame 920 connected to the housing body 910, and the drum 100 is rotatably arranged in the housing body 910, and the support frame 920 is provided with a cartridge mounting detent 921 for mounting the storage cartridge and a fixing structure for fixing the storage cartridge, wherein the fixing structure includes a positioning portion 922, a buckle 923, and an elastic member 924, the storage cartridge is positioned on the mounting detent through the positioning portion 922, the buckle 923 fixes the storage cartridge relative to the cartridge mounting detent 921, and the elastic member 924 provides an elastic force in the fourth direction (e.g., direction V in Figure 3 ) to make the storage cartridge have a movement tendency to move towards the housing body 910, and the surface of the developing roller 300 elastically presses against the outer surface of the drum 100 to achieve stable transmission of the developer between the developing roller 300 and the drum 100, and the fourth direction is perpendicular to the first direction to make the developing roller 300 press against the surface of the drum 100 in the direction perpendicular to the axis of the drum 100, thereby achieving uniform transportation of the developer to the surface position of the drum 100. For reference, see Figure 2 The elastic member 924 is arranged at one end of the support frame 920 away from the housing body 910, and includes a force applying portion movable relative to the support frame 920 in the fourth direction and an elastic member such as a spring or a tension spring arranged between the force applying portion and the support frame 920 to provide an elastic force (e.g., force F in Figure 3 ). The positioning portion 922 is arranged at the other end of the support frame 920 close to the housing body 910 and can be designed as a positioning groove with an opening, and the storage cartridge is provided with a positioning protrusion at one end thereof in the fourth direction, the positioning protrusion enters the positioning groove through the opening to achieve positioning of the one end, and the other end is elastically pressed by the elastic member 924, and the storage cartridge is fixed in the support frame 920 through the buckle 923 arranged on the support frame 920 or the storage cartridge. Of course, the assembly structure of the storage cartridge on the photosensitive member can also be other structures in the prior art, which are within the scope of the present application.

[0048] In the embodiment, the acting portion 711a is a friction surface in contact with the surface of the drum 100, which is pressed against the surface position of the drum 100 when the acting portion 711a is in the initial state and the storage cartridge is matched with the photosensitive member, and drives the first portion 711 to move and further drives the second portion 712 to perform the first movement by using the friction force generated by the extrusion with the surface of the drum 100 when the drum 100 rotates. The driving force transmission mode by using the friction surface can realize the power transmission without corresponding structural changes to the outer surface of the drum 100, thereby reducing the production cost, and when the storage cartridge is reassembled on the photosensitive member, it does not cause the reassembly calibration difficulty problem caused by the gear engagement structure, and facilitates the independent replacement of the storage cartridge in the split structure. In combination with the mounting structure of the storage cartridge on the photosensitive member, when the elastic member 924 provides the fourth direction elastic force to make the storage cartridge close to the shell body 910, the acting portion 711a will also be pressed against the outer surface of the corresponding drum 100 due to the elastic force, and because the first portion 711 is arranged at the roller end 310 position, the contact position of the acting portion 711a is located at the end of the drum 100, which will not interfere with the imaging surface of the drum 100. Therefore, not only the imaging stability of the drum 100 is ensured, but also the transmission of the driving force on the power receiving member 710 is realized.

[0049] Specifically, the first portion 711 is made of an elastic material, and when the first portion 711 is an elastic material, it can be elastically deformed under the extrusion force, for example, in the above embodiment, the acting portion 711a is a friction surface, and when the elastic member 924 extrudes the first portion 711 on the surface of the drum 100, the first portion 711 will be deformed relative to the surface of the drum 100. The deformation increases the contact area of the first portion 711 on the surface of the drum 100, and further increases the friction force between them, thereby effectively ensuring the stable transmission of power between the drum 100 and the first portion 711. It should be noted that when the eighth axis coincides with the second axis, the first diameter of the first portion 711 relative to its axis is greater than the second diameter of the transmission surface of the developing roller 300 for transmitting the developer relative to its axis, so that the first portion 711 has a protruding portion relative to the developing roller 300 in the undeformed state, which is deformed to increase the contact area when extruded on the surface of the drum 100. This structure can make the power receiving member 710 stably receive the driving force from the drum 100, and also reduce the occupied space of the transmission member 700 at the end of the storage cartridge, so that the design size of the entire storage cartridge is smaller. The elastic material can be rubber or the like.

[0050] In combination with the above-mentioned embodiments, if the acting portion 711a only contacts the drum 100 in the initial running stroke of the storage cartridge, the protruding portion of the first portion 711 is circumferentially arranged relative to the eighth axis but does not form a closed contact surface, and has a recessed portion that is separated from the surface of the drum 100. In the initial state, the protruding portion is in contact with the surface of the drum 100, and after the running of the protruding portion relative to the surface of the drum 100 is completed, the recessed portion is directed toward the surface of the drum 100 to separate the first portion 711 from the drum 100. At this time, the first portion 711 no longer receives the driving force from the drum 100, and the first portion 711 can be kept in a separated state from the surface of the drum 100 by a spring or the like. The acting portion 711a can be implemented as a tooth portion, a friction surface, or the like.

[0051] In addition, the first portion 711 and the second portion 712 can be arranged as the same portion on the drum 100. When the portion engages the outer surface of the drum 100, it serves as the first portion 711 to receive the driving force from the drum 100, and when the portion is separated from the surface of the drum 100, it serves as the second portion 712 as the driving member of the detected member 810. For example, the power receiving member 710 includes a rubber ring arranged to rotate relative to the cartridge body 200 along the eighth axis and can simultaneously serve as the first portion 711 and the second portion 712. When serving as the first portion 711, the rubber ring is in contact with the surface of the drum 100 to be driven to rotate, and when serving as the second portion 712, the rubber ring transmits the received driving force to the next component by the friction force of the circumferential surface. Of course, the power receiving member 710 of the present embodiment can also be arranged as a gear or the like, which is within the scope of the present application.

[0052] In the embodiment shown in Figure 3 , the second portion 712 includes an engaging tooth portion arranged in the first direction and a connecting portion 712a arranged as a cylindrical surface. The first portion 711 is sleeved on the connecting portion 712a as a rubber ring, so that the first portion 711 and the second portion 712 combine to form an integral power receiving member 710.

[0053] In another embodiment, the transmission component 700 further includes a power transmission member 720. One portion of the power transmission member 720 is connected to the second portion 712, and another portion is connected to the detected member 810. The power transmission member 720 is located between the power receiving member 710 and the detected member 810 on the cartridge body 200. One portion of the power transmission member 720 is used to transmit the driving force generated by the first movement of the second portion 712, and another portion is used to transmit the driving force to the detected member 810, so as to realize the transmission of the driving force between the detected member 810 and the power receiving member 710. However, the power transmission member 720 does not intersect with the shaft coupling component 400 and is an independent power transmission chain arranged on the cartridge body 200, so as to avoid affecting the transmission of the driving force on the cartridge body 200 by the shaft coupling component 400 in the storage cartridge.

[0054] Referring to Figure 3 and Figure 9 , the second part 712 includes a first tooth portion 712b (i.e. the aforementioned engagement tooth portion) arranged circumferentially around the ninth axis, and the power transmission member 720 includes a power transmission gear 721 including a second tooth portion 721a engageable with the first tooth portion 712b. The power transmission member 720 and the second part 712 are connected through a gear connection, which can ensure the accuracy of power transmission. Specifically, the power transmission member 720 further includes at least one intermediate gear 722, each of which is engaged with each other, and the detected member 810 includes a third tooth portion 812 engaged with the at least one intermediate gear 722, the intermediate gear 722 is engaged with the power transmission gear 721 and transmits power to the detected member 810, so that the power transmission member 720 forms a gear set between the power receiving member 710 and the detected member 810, which can ensure the accurate transmission of power.

[0055] In one embodiment, the first movement of the second part 712 does not change the movement trajectory due to the rotation of the developing roller 300, specifically, when the developing roller 300 rotates around the second axis under the action of the shaft coupling component 400, it does not affect the state of the second part 712 at this time, including the state of being stationary relative to the cartridge 200 or the state of moving relative to the cartridge 200, and cannot drive the power receiving member 710 through the second part 712 or the first part 711, and when the developing roller 300 is in a state of being stationary relative to the cartridge, the second part 712 performs the first movement under the driving force received by the first part 711 from the drum 100, and will not be affected by the developing roller 300 and will not drive the developing roller 300 to rotate correspondingly. For example, referring to Figure 3 and Figure 9 In the foregoing embodiment, the power receiving member 710 is rotatably arranged at the roller end 310 but does not affect the rotation of the developing roller 300, and the developing roller 300 also does not interfere with the movement process of the power receiving member 710, so that the transmission chain driven by the driving force received by the power receiving member 710 and the transmission chain in which the driving force received by the shaft coupling component 400 is located are two transmission paths that do not interfere with each other. In addition, the second part also does not change the movement trajectory due to the rotation of the supply roller 600, and the power transmission member 720 that transmits the driving force from the drum 100 between the power receiving member 710 and the detected member does not contact or does not exist. For example, referring to Figure 3 the movement interference between the power transmission gear 721 and the intermediate gear 722 of the power transmission member 720 and the end of the supply roller 600, the driving gear set includes a second gear 430 for driving the supply roller 600, so that the developing roller 300 and the supply roller 600 are both driven by the shaft coupling component 400.

[0056] In addition, the stirring frame 500 can be driven by the coupling member 400 in the embodiment, or can be driven by the driving force received by the power receiving member 710. In Figure 3 In the embodiment shown, the stirring frame 500 is arranged on the transmission chain where the detected member 810 is located, and each intermediate gear 722 of the power transmission member 720 includes a third gear 722a for driving the stirring frame 500. This structure can make the stirring frame 500 separate from the transmission chain where the developing roller 300 and the supply roller 600 are located, and reduce the load on the transmission chain where the developing roller 300 and the supply roller 600 are located, so as to effectively ensure the smooth transmission of the developer by the developing roller 300 and the supply roller 600.

[0057] Continuing to refer to Figure 5 The cartridge 200 has a first end portion 240 and a second end portion 250 arranged along the first direction, and the second end portion 250 is spaced apart from the first end portion 240 along the first direction. The power receiving member 710 is arranged at the first end portion 240, and the coupling driving member 410 is arranged at the second end portion 250. Thus, the two driving force receiving members are arranged at the two end portions of the cartridge 200, respectively, which can avoid the problem of space congestion caused by the newly added power receiving member 710 arranged at the same end portion as the coupling driving member 410. The power transmission gears 721, intermediate gears 722, etc. on the power transmission member 720 of the transmission member 700 can be squeezed into the space occupied by the first gear 420 and the second gear 430, so that the space layout on the cartridge is more reasonable. In addition, the two transmission chains can be prevented from affecting each other, which is beneficial to the miniaturization of the cartridge and the processing device as a whole, and shortens the longitudinal and transverse dimensions.

[0058] In one embodiment, the power receiving member 710 and the detected member 810 are both arranged at the first end portion 240 of the housing, so that the transmission chain composed of the power receiving member 710 and the detected member 810 is located at the first end portion 240. The transmission member 700 can be integrated at the first end portion 240, which shortens the size of the transmission chain and ensures the effective transmission of power on the transmission chain. In addition, the detected member 810 and the power receiving member 710 are arranged at different ends from the coupling member 400, which prevents the coupling member 400 and the detected member 810 from affecting each other, and shortens the longitudinal dimension of the cartridge.

[0059] Specifically, referring to Figure 5The box body 200 comprises a box body 260, a first end cover 270 arranged on the first end 240 and detachably assembled with the box body 260, a second end cover 280 arranged on the second end 250 and detachably assembled with the box body 260, the first end cover 270 and the box body 260 form a first space between the outer side wall of the first end 240, the power receiving member 710 and the power transmission member 720, and the detected member 810 are arranged in the first space to be protected by the first end cover 270, and the detection part 811 is exposed to the opening of the first end 240 at least in the detection position when the detection part 811 moves in the activity range, so that the detection part 811 can be inductively recognized by the detection structure on the device body. The second end cover 280 and the box body 260 form a second space between the outer side wall of the second end 250, the shaft coupling part 400 and the driving gear set are arranged in the second space. The two ends of the box body 200 are protected by the two detachably arranged end covers, which can ensure the compactness of the overall structure of the storage box, and facilitate the disassembly and replacement of the corresponding parts on the storage box, and the overall structure is stable. The first end cover 270 and the second end cover 280 can be composed of one or two parts, for example, the first end cover 270 comprises a first cover for covering the detected member 810 and a second cover for covering the transmission part 700, and the second end cover 280 is an integral whole for covering the shaft coupling part 400, which is within the scope of the present application.

[0060] Continuing to refer to Figure 3 In a second direction intersecting the first direction (which can be the same as the fourth direction), the first distance between the detected member 810 and the developing roller 300 is greater than the second distance between the power receiving member 710 and the developing roller 300, so that the power receiving member 710 is closer to the drum 100 than the detected member 810, thereby better receiving the driving force from the drum 100, and the detected member 810 is away from the drum 100 and will not be disturbed by the drum 100, avoiding the influence of the detection structure on the progress of the imaging process. Among them, in the second direction, the second part 712 has a gap with the outer surface of the drum 100, so that the first movement of the second part 712 and the rotation movement of the drum 100 do not affect each other.

[0061] In another embodiment, the storage box further comprises an electric transmission component, which comprises an electrode 290 arranged on the second end portion 250 of the box body 200 and having an exposed portion outside the second end cover 280 to contact an electric connection structure on the photosensitive member or the body of the apparatus, and an electric connection member. The electrode 290 can be arranged as a metal sheet, and the electric connection member is arranged to contact the developing roller 300 to charge the surface of the developing roller 300, so that the developing roller 300 can better attract the toner to the surface of the drum 100 to form an image when conveying the toner. The electric connection member has an extension portion extending from the second end portion 250 to the first end portion 240 to uniformly charge the developing roller 300 in the direction of the second axis extending in the first direction. In this embodiment, the electric connection member is arranged as a metal round rod as a roller shaft penetrating the developing roller 300, which can receive the electricity of the electrode 290 in a contact manner and transmit to the surface of the developing roller 300. In addition, the electric connection member can also be a powder scraping component arranged on the toner outlet 220, which is made of a conductive material such as metal, and can charge the toner on the surface of the developing roller 300 to meet the imaging needs. The electrode 290 is arranged on the second end portion 250, which can be isolated from the detected member 810 and the transmission component 700 on the first end portion 240, so as to avoid affecting the detection process of the detected member 800 and reduce the interference of the related structures of the developing roller 300, the supply roller 600 and other components on the detected structure.

[0062] In addition, in the embodiment shown in Figure 3 , the plurality of intermediate gears 722 of the power transmission component 720 are all straight gears or helical gears to transmit the driving force to the detected member 810 in a direction perpendicular to the first direction to rotate the detected member 810 about the sixth axis; in the embodiment shown in Figure 7 , the plurality of intermediate gears 722 of the power transmission component 720 comprise straight gears or helical gears, and bevel gears for changing the transmission direction of the driving force to enable the detected member 810 to rotate about the seventh axis. In the two embodiments, the power receiving member 710 always maintains contact with the drum 100 to receive the driving force from the drum 100, and the third tooth portion 812 of the detected member 810 used to connect the intermediate gears 722 is provided with a tooth missing portion 813. In the initial position, the third tooth portion 812 is in meshing state with the intermediate gears 722, and after running to a certain angle, the detected member 810 completes the detection stroke, and the tooth missing portion 813 is away from the meshing with the intermediate gears 722. The detected member 810 in the disengaged position can be kept in this position by an elastic component such as a tension spring. Of course, the second movement of the detected member 810 can also be other movement trajectories capable of enabling the detection portion 811 to be detected, and the transmission mode of the power transmission component 720 is adjusted according to the movement form, which is within the scope of the present application.

[0063] Finally, it should be noted that the above description is merely the best embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and simple replacements to the technical solutions of the present application without departing from the scope of the present application, which are all within the protection scope of the present application.
