     TECHNICAL FIELD 
     The present disclosure relates to the field of electronic imaging technology, and in particular to a toner cartridge. 
     BACKGROUND 
     A toner cartridge is often removably mounted in an electronic imaging device. The electronic imaging device may include a drive unit to output a rotation driving force. The toner cartridge may usually include a drive assembly for receiving a rotation-force, a developing unit, a toner, a toner control unit and a frame that contains these units. In addition, based on different types of toner cartridge structures, the toner cartridge may also include a photosensitive unit, a charging unit, a cleaning unit and a stirring unit, etc. The drive assembly of the toner cartridge may be disposed at one side of the toner cartridge along an axial direction of the developing unit or the photosensitive unit. Through the drive assembly, the toner cartridge can be engaged with the drive unit of the electronic imaging device to transmit the rotation driving force into the toner cartridge. A rotation unit (including the developing unit, the photosensitive unit, and the stirring unit, etc.) of the toner cartridge is driven to rotate and the developing operation of the electronic imaging device can be executed. 
     Before the electronic image device can execute the developing operation (i.e., generally called “printing”), a user needs to mount the toner cartridge into the electronic imaging device. The drive assembly of the toner cartridge can be in contact and engaged with the drive unit of the electronic imaging device. 
     As shown in  FIG. 1 , a toner cartridge C may be mounted in an electronic imaging device (not shown) along X1 direction (the X1 direction is approximately perpendicular to the axial direction of the developing unit). Guide rails (F 11 , F 21 ) on left and right inner side panels of the electronic imaging device may be configured to support and guide the toner cartridge C to enter the electronic imaging device. When the toner cartridge C is mounted along the guide rails (F 11 , F 21 ) into the electronic imaging device, as shown in  FIG. 2 , a drive assembly  100  disposed at one side of the toner cartridge C can also be moved along the X1 direction to be in contact and engaged with a drive unit  900  of the electronic imaging device. The drive unit  900  is relatively fixed in the electronic imaging device and is only rotatable along the axis of the drive unit  900 . As the drive assembly  100  moves along the X1 direction to engage with the drive unit  900 , it may be possible that the rotation-driving-force receiving assembly  110  of the drive assembly  100  structurally interferes with the drive unit  900 . 
     Therefore, in current technologies, when the rotation-driving-force receiving assembly  110  is structurally interfering with the drive unit  900 , with pressure from the drive unit  900 , the rotation-driving-force receiving assembly  110  can be contracted inward in the axial direction of the rotation-driving-force receiving assembly  110 , so that the structural interference may be avoided. When the rotation-driving-force receiving assembly  110  is further moved till approximately coaxial with the drive unit  900 , the structural interference between the rotation-driving-force receiving member  110  and the drive unit  900  may be avoided. Because of an elastic force of a spring disposed in the drive assembly  100 , the rotation-driving-force receiving assembly  110  can protrude to be in contact and engaged with the drive unit  900 . 
     After the toner cartridge is mounted in the electronic imaging device (not shown), to ensure the electronic imaging device can function well, it is usually necessary to trigger an inspection device to inspect whether the toner cartridge C is mounted correctly. However, there is no simple and effective approach to trigger the inspection device. 
     SUMMARY 
     The present disclosure provides a toner cartridge and an electronic imaging device to solve technical problems of inspecting whether a matching toner cartridge is correctly mounted into an electronic imaging device, when the toner cartridge is mounted into the electronic imaging device. 
     A technical solution according to the present disclosure is to provide a toner cartridge. The toner cartridge can be removably mounted in an electronic imaging device. The electronic imaging device may include a rotatable toner cartridge guide rail, and the toner cartridge can be mounted at the toner cartridge guide rail. A locating column may be disposed at one side of the toner cartridge, and the locating column can be supported by the toner cartridge guide rail. The locating column can be moved by an external force to rotate the toner cartridge guide rail. The electronic imaging device may also include an inspection device, which includes a trigger switch. When the toner cartridge is rotated because of the external force exerting on the locating column, the toner cartridge guide rail may touch the trigger switch and turn on the trigger switch. 
     In some embodiments, a side panel may be disposed at one side of the toner cartridge, and the locating column can be slid relative to the side panel. 
     In some embodiments, a slider may be disposed on the side panel, and the locating column may be disposed on the slider. Under the external force, the slider can drive the locating column to slide relative to the side panel. 
     In some embodiments, the slider may include a protrusion, and a chute may be disposed on the side panel. Through the protrusion, the slider can be slid on the chute of the side panel. 
     In some embodiments, the toner cartridge may further include a developing unit. Compared to the location of a slider slid by the external force, the slider may be located closer to the developing unit before the external force is applied for sliding the slider. 
     In some embodiments, an elastic resetting part may be further disposed between the slider and the side panel. The resetting part is configured to reset the slider when no external force exerting on the slider. 
     In some embodiments, the slider may further include a cartridge action part. The cartridge action part can be moved by an external force to cause the slider to drive the locating column to move. The cartridge action part may be disposed on the slider and protrude downward. 
     In some embodiments, the cartridge action part may have a protruding rod-shaped or hook-shaped structure. 
     In some embodiments, the cartridge action part and the slider may be integrally or separately configured. 
     In some embodiments, the electronic imaging device may include a pulling part, and the pulling part may be configured to drag the cartridge action part to move. 
     In some embodiments, a driving-force receiving member may be disposed at one side of the toner cartridge and configured to receive a rotation driving force from the drive unit of the electronic imaging device. The driving-force receiving unit and the locating column may be disposed at the same side of the toner cartridge. 
     In some embodiments, the toner cartridge may further include a flange. The flange may be configured receive the rotation driving force from the driving-force receiving member, and the driving-force receiving member can be extended and contracted relative to the flange. 
     In some embodiments, a claw may be disposed at an upper end of the driving-force receiving member, and the claw may be tilted or swung relative to the driving-force receiving member. 
     In some embodiments, the toner cartridge may further include a control mechanism, and the control mechanism may be configured to control the driving-force receiving member to extend and contract. 
     In some embodiments, when subjected to a force, the cartridge action part may be configured to push the control mechanism, so that the control mechanism can control the driving-force receiving member to extend and contract. 
     In some embodiments, the toner cartridge may include a developing chamber, and the side panel is fixed to one side of the developing chamber. The developing chamber and the side panel may not be rotatable along with a rotation of the toner cartridge guide rails. 
     The technical solutions provided by the embodiments of the present application can achieve a beneficial effect: using the above technical solutions, whether the toner cartridge is correctly mounted can be determined by a conduction state of the inspection device. 
     Other aspects or embodiments of the present disclosure can be understood by those skilled in the art in light of the description, the claims, and the drawings of the present disclosure.

The sliding surface  224  of the pressing element  220  can be vertically sliding matched with the sliding surface  294  of the end cap  290 . To prevent the drive assembly  200  from detaching from the toner cartridge b, the end cap  290  can be mounted on the side panel b 2  of the toner cartridge b by threading, glutting or wielding, etc. 
     According to the above description, one end of the elastic element  250  may abut against the connecting part  260  and two ends of the connecting part  260  can be placed (in some cases inserted) in the limiting chute  273 , so that the connecting part  260  can be elastically movable along the limiting chute  273 , and the driving-force receiving member  210  that is connected to the connecting part  260  may also be extended and contracted elastically relative to the flange  270 . Similarly, the slider  230  may be connected to the driving-force receiving member  210 , and the pressing element  220  may be connected to the slider  230 , therefore, the slider  230  and the pressing element  220  can also be moved along with the movement of the driving-force receiving member  210 . When the end cap  290  is covering at the slider  230 , because of the elastic force of the elastic element  250 , the inclined sliding surface  231  of the slider  230  may abut against the inclined sliding surface  291  to limit the amount that the driving-force receiving member  210  can protrude in the drive assembly  200 . Therefore, the driving-force receiving member  210  can be axially extended and contracted by the elastic force along a direction Y (the direction Y may be approximately coaxial or coincident with the axial direction of the developing unit  30  or the photosensitive unit  10 , and approximately perpendicular to the direction X). 
     As shown in  FIG. 9  to  FIG. 11 , the driving-force receiving member  210  disposed in the drive assembly  200  can implement the following operation process (to facilitate understanding the operation process of the driving-force receiving member  210  in the flange  270 , some parts of the drive assembly  200  are not shown). (1) Under the elastic force of the elastic element  250 , the driving-force receiving member  210  can be axially extended and contracted along the direction Y. (2) As shown in  FIG. 9 , which is viewed from a lengthwise direction of the connecting part  260 , the driving-force receiving member  210  can be assembled and matched with the connecting part  260  through the notch  215 . Therefore, the driving-force receiving member  210  can be slidable along the lengthwise direction of the connecting part  260 , i.e., in the flange  270 , the driving-force receiving member  210  can achieve a parallel displacement of certain distance relative to the rotation axis of the flange  270 . (3) As shown in  FIG. 10  and  FIG. 11 , which are viewed from the direction of an end face of the connecting part  260 , the connecting part  260  has a centrally protruding crank-shaped structure, and two ends of the connecting part  260  can be placed (in some cases inserted) in the chute  273 . Therefore, the driving-force receiving member  210  can be engaged with the connecting part  260  through the notch  215  and swing left and right through the centrally protruding crank-shaped structure of the connecting part  260 , i.e., in the flange  270 , the driving-force receiving member  210  can achieve a parallel displacement of certain distance relative to the rotation axis of the flange  270 . 
     As shown in  FIG. 12  and  FIG. 13 , after the drive assembly  200  is assembled, when no external force is exerting on the drive assembly  200 , the driving-force receiving member  210  can be kept protruding outward by the elastic force of the elastic element  250 , and the pressure receiving element  221  of the pressing element  220  can also protrude outward relative to the outer surface of the end cap  290 . At this time, the driving-force receiving member  210  is in an initial position. When the pressure receiving element  221  is pressed by an external force F 1 , the pressing element  220  can be pressed to move downward to drive the slider  230 . The slider  230  can drive the driving-force receiving member  210  to move downward along the direction Y and compress the elastic element  250 . At this time, the driving-force receiving member  210  is in a contracting position. A height H 1  from the top of the driving-force receiving member  210  in the initial position to the outer surface of the end cap  290  is greater than a height H 2  from the top of the driving-force receiving member  210  in the contracting position to the outer surface of the end cap  290 . 
       FIG. 13  shows a side view of the toner cartridge b. A rotation axis of a toner feed unit  40  may be disposed within the contour projection range of the flange  270 , or the metal shaft  45  of the toner feed unit  40  maybe at least partially overlap with the flange  270 . 
     Control Member 
     A control member of the drive unit  200  may include a set of parts that enable the driving-force receiving member  210  to extend and contract relative to the flange  270 . The control member of the drive unit  200  or the set of parts may include the pressing element  220 , the slider  230 , and the elastic element  250 . 
     Cartridge Action Part 
       FIG. 14  shows a side view of the toner cartridge b. A cartridge action part b 4  may be disposed at the bottom of the developing chamber b 100  of the toner cartridge b. The cartridge action part b 4  may have a rod-shaped or a hook-shaped structure projecting downward and outward. The cartridge action part b 4  can be connected to the developing chamber b 100 , or the side panel (b 1  or b 2 ) of the developing chamber b 100 . When the external force is exerting on the cartridge action part b 4 , through the cartridge action part b 4 , the external force can also exert on the toner cartridge b. 
     Control Mode 1 of Control Mechanism 
     As shown in  FIG. 15  to  FIG. 17 , a control mechanism  600  can be disposed in the side panel b 2  of the toner cartridge b, and the control mechanism  600  may include a traction element  610  and a control action part  620 . The traction element  610  may be a traction cord. Similar to the cartridge action part b 4 , the control action part  620  may have a rod-shaped or a hook-shaped structure protruding downward and outward. One end of the traction element  610  can pass through a bottom hole  275   a  of the flange  270  and be connected to the bottom of the driving-force receiving member  210 . The other end of the traction element  610  can be connected to the control action part  620 . As viewed from a side of the drive assembly  200 , when an external force F 2  is not exerting on the control action part  620 , through the traction element  610 , the control action part  620  can be displaced by the driving-force receiving member  210  further than the cartridge action part b 4  in a X1 direction. The distance between the front end of the control action part  620  and the front end of the cartridge action part b 4  may be L 1 . When the control action part  620  is pushed by the external force F 2  (the direction of F 2  may be approximately opposite to the X1 direction). The control action part can be moved by the external force F 2  in a X2 direction (opposite to the X1 direction), and through the traction  610 , drag the driving-force receiving member  210  to contract inward relative to the flange  270 . When the control action part  620  is moved by the external force to be flush with the cartridge action part b 4 , the pressure receiving element  221  of the pressing element  220  may not protrude out of the outer surface of the end cap  290 . Once the external force does not exert on the control action part  620 , the elastic force provided by the compressed elastic element  250  can cause the driving-force receiving member  210  to protrude outward, and through the traction element  610 , drag the control action part  620  to the position before the external force is applied on the control action part. That is, the distance between the front end of the control action part  620  and the front end of the cartridge action part b 4  may be L 1 . When the external force F 2  is not exerting on the control action part  620 , the function of the control mechanism  600  can cause the driving-force receiving member  210  to be in an initial position. When the external force F 2  is exerting on the control action part  620 , the driving-force receiving member  210  may be in a contracting position. A distance L 2  from the top of the claws  211  of a driving-force receiving member  210  in the initial position to the surface of the end cap  290  may be greater than a distance L 3  from the top of the claw  211  of a driving-force receiving member  210  in the contracting position to the surface of the end cap  290 . The control mechanism  600  may also include a revolving flange  611  that can make the traction element  610  to change direction. 
     Control Mode 2 of Control Mechanism 
     In addition, an optional configuration of the control mechanism is shown in  FIG. 18  to  FIG. 21 . The control mechanism  600  may include a control action part  620  and a connecting member  630 . The control action part  620  and the connecting member  630  may be rotatably connected. The connecting member  630  may have an elongated rod-shaped structure. The front end of the connecting member  630  may have a fork-shaped structure and include an inclined surface  631 . The control mechanism  600  may further include a resetting part  810  (a rubber band or a tension spring). One end of the resetting part  810  may be connected to the control action part  620 , and the other end of the resetting part  810  may be connected to the side panel b 2  or the developing chamber b 100 . To cooperate with the control mechanism  600 , the connecting member  216  of the driving-force receiving member  210  may further include an elongated rod passing through the flange  270 . A distal end of the elongate rod may include a disc, and an inclined surface  216   a  may be disposed on the disc. Similar to the control mechanism described above, when the external force F 2  is not applied, the control action part  620  and the connecting member  630  can be moved forward in the X1 direction by the elastic traction action of the resetting part  810 , and the inclined surface  631  of the connecting member  630  may not abut against the inclined surface  216   a  at the distal end of the driving-force receiving member  210 . When the external force F 2  is exerting on the control action part  620  to drive the connecting part  630  to move forward in the X2 direction, the inclined surface  631  of the connecting part  630  may abut against the inclined surface  216   a  and press the driving-force receiving member  210  downward. Therefore, the driving-force receiving member  210  can be contracted inward relative to the flange  270 . Basically, the same functions and effects of Control Mode 1 of the control mechanism  600  can be achieved by Control Mode 2. 
     Control Mode 3 of Control Mechanism 
     In addition, another optional configuration of the control mechanism is shown in  FIG. 22  to  FIG. 26 . The control mechanism  600  may include a control action part  620 , a connecting member  621 , a positioning ring  640 , and a guide sleeve  650 . The front end of the connecting member  621  may include a connecting column  622 . The outer annular surface of the positioning ring  640  may include a matching hole  642  and the bottom of the positioning ring  640  may include an inclined surface  641 . The guide sleeve  650  may include an inclined surface  651 , a limiting hole  652  and a through hole  655  may be disposed at the center of the guide sleeve  650 . The control mechanism  600  and the driving-force receiving member  210  may be connected in the following manner. The positioning ring  640  can be placed on the guide sleeve  650 ; the inclined surface  641  may abut against and be matched with the inclined surface  651 ; an extended elongated rod body of the connecting member  216  can pass through the positioning ring  640  and the through hole  655  of the guide sleeve  650 ; a protrusion  216   b  disposed at a distal end of elongated rod body can abut against the bottom of the guide sleeve  650 ; the connecting column  622  at the front end of the connecting member  621  can be rotatably connected to and matched with the matching hole  642  of the positioning ring  640 ; and the control mechanism may also include a resetting part  810 . Referring to Control Mode 1 and 2, when the external force F 2  is not exerting on the control action part  620 , the control action part  620  and the connecting member  621  can be moved forward in the X1 direction by the elastic traction of the resetting part  810 ; the inclined panel of the positioning ring  640  may not abut against the inclined surface  651  of the guide sleeve  650 ; and the positioning ring  640  may be matching attached to the guide sleeve  650 . At this time, the driving-force receiving member  210  is in the initial position. When the external force F 2  is exerting on the control action part  620 , the connecting column  622  at the front end of the connecting member  621  can drag the matching hole  642  to rotate the positioning ring  640 . As the positioning ring  640  is rotated, the inclined surface  641  may abut against the inclined surface  651 , so that the guide sleeve  650  may be moved downward and separated from the positioning ring  640 . Because the limiting hole  652  of the guide sleeve  650  is relatively positioned by the side panel b 2  or a protrusion b 2   a  of the developing chamber b 100 , the guide sleeve  650  can be moved only along the axial direction but cannot be rotated relative to the axial direction. While being moved downward, the guide sleeve  650  can push the protrusion  216   b  disposed at the distal end of the driving-force receiving member  210 , so that the driving-force receiving member  210  may be contracted inward relative to the flange  270  along the rotation axial of the flange  270 . Basically, the same functions and effects of Control Mode 1/Control Mode 2 of the control mechanism  600  can be achieved by Control Mode 3. 
     Referring to  FIG. 14 , the cartridge action part b 4  and the control mechanism  600  are viewed from one side of the toner cartridge b or in the axial direction of the driving-force receiving member  210 . At the bottom of the toner cartridge b, the cartridge action part b 4  and the control mechanism  600  may be disposed as one in front of another. Compared to the cartridge action part b 4 , the control mechanism  600  may be closer to the driving-force receiving member  210 , while compared to the control mechanism, the cartridge action part b 4  may be closer to the rear end of the developing chamber b 100 . 
     Electronic Imaging Device 
     As shown in  FIG. 27 , an electronic imaging device P may include a cover P 1 , a driving motor M 1 , a toner cartridge guide rail F 100 , a photosensitive assembly guide rail F 200 , a drive unit  900 , a drive unit  900   a , a pulling part F 300 , and a traction element F 120  (a rubber band or a tension spring). The drive unit  900  and the drive unit  900   a  can be driven to rotate by the driving motor M 1 . The toner cartridge guide rail F 100  can be rotated around a rotation point F 101  relative to the photosensitive assembly guide rail F 200 . One end of the traction element F 120  may be connected to the front end of the toner cartridge guide rail F 100 , and the other end of the traction element F 120  may be fixedly connected in the electronic imaging device P. The front end of the toner cartridge guide rail F 100  may also include an elastically extendable stopper F 110 . The pulling part F 300 , which may be disposed below the cartridge guide rail F 100 , can be driven to move certain front-and-rear displacement or certain rotation displacement by the driving motor M 1  or other driving mechanisms. The pulling part F 300  may have a hook-shaped structure. 
     As shown in  FIG. 28 , when a force is exerting on the toner cartridge guide rail  100 , the toner cartridge guide rail F 100  can achieve certain amount of rotation relative to the rotation point F 101  and may be in a displacement position. Once the force is removed from the toner cartridge guide rail F 100 , the toner cartridge guide rail F 100  can be dragged by the pulling part F 120  to return to the initial position before the rotation. 
     In addition, the electronic imaging device P may also include a front frame F 400  with an inclined surface. When viewed from a side of the electronic imaging device P, the front frame F 400  may be disposed at one side of the toner cartridge guide rail F 100 , and the photosensitive assembly F 200  may be disposed at the other side of the toner cartridge guide rail F 100 . 
     Inspection Mechanism of the Electronic Imaging Device 
     As shown in  FIG. 27  and  FIG. 28 , the electronic imaging device P may further include an inspection device PD 1  and a trigger switch SW 1  for enabling the inspection device PD 1  to perform an inspection operation. The toner cartridge guide rail F 100  may include a pushing block F 103 , and optionally, the pushing block F 103  can be disposed at a side where the driving assembly of the electronic imaging device P is located (e.g. the side of the guide rail F 11  close to the drive unit  900 , referring to the structure of the guide rail shown in  FIG. 1 ). When the toner cartridge guide F 100  is pushed by a force to rotate in a clockwise direction around the rotation point F 101  relative to the photosensitive assembly guide rail F 200 , the pushing block F 103  of the toner cartridge guide rail F 100  can be rotated along with the rotation of the toner cartridge guide F 100  to touch the trigger switch SW 1 . So as that the inspection device PD 1  may start inspecting and generate a signal that the trigger switch SW 1  is turned on. When the toner cartridge guide rail F 100  is dragged by the traction element F 120  to rotate counterclockwise around the rotation point F 101  relative to the photosensitive assembly guide rail F 200  and return to the initial position before rotation, the pushing block F 103  may no longer touch the trigger switch SW 1 . So as that the SW 1  may be turned off, and the inspection device PD 1  may generate a signal that the trigger switch SW 1  is turned off. 
     Thus, through the signal obtained from the inspection device PD 1 , the electronic imaging device P can determine whether a toner cartridge mounted by a user matches the electronic imaging device P. For example, if the toner cartridge mounted by the user matches the electronic imaging device P, the generated inspection signal can be “ON-OFF” or “ON-OFF-ON-OFF”. If the toner cartridge mounted by the user and the electronic imaging device P can complete an inspection process to generate the above inspection signal, the electronic imaging device P can automatically determine that a matching toner cartridge is mounted by the user, and the electronic imaging device P may display that the inspection process is completed so that the user can perform normal developing operation (printing). If the inspection process cannot be completed, for example, only “ON” or “OFF” signal is generated, the electronic imaging device P may display that the inspection process is not completed, and the normal developing operation (printing) cannot be performed. 
     Pulling Part of the Electronic Imaging Device 
     When the pulling part F 300  of the electronic imaging device P acts on the cartridge action part b 4 , the pulling part F 300  may need to be moved forward to the front of the cartridge action part b 4  and moved backward to act on the cartridge action part b 4 . Therefore, there may be several displacement modes of the pulling piece F 300  as following. 
     Displacement Mode of the Pulling Part: Mounting of the Toner Cartridge and the Photosensitive Assembly 
     As shown in  FIG. 29  to  FIG. 31 , with the cover P 1  opened, the photosensitive assembly a and the toner cartridge b can be mounted in the electronic imaging device P. Referring to  FIG. 31 , when the cover P 1  is open, the drive unit  900   a  may be contracted inward along the rotation axis of the drive unit  900   a . Therefore, during the mounting processing of the photosensitive assembly a into the electronic imaging device P along the photosensitive assembly guide rail F 200 , the driving element a 110  of the photosensitive assembly a may not structurally interfere with the drive unit  900   a.    
     The drive unit  900 , which is engaged with the driving-force receiving member  210 , can only be rotated along the rotation axis of the electronic imaging device P in the electronic imaging device P, but cannot be contracted and extended axially as the drive unit  900   a . Therefore, when the toner cartridge b is mounted into the electronic imaging device P, it may be necessary to prevent the driving-force receiving member  210  from structurally interfering with the drive unit  900 . 
     As shown in  FIG. 32  to  FIG. 34 , the toner cartridge b can be mounted into the electronic imaging device P along the toner cartridge guide rail F 100  in the mounting direction, i.e., the X1 direction. During the mounting process of the toner cartridge, the pressing element member  221  of the drive assembly  200  may abut against and press the front end of the toner cartridge guide rail F 100 , so that the whole pressing element  220  can be moved downward relative to the end cap  290 . The pressing element  220  moving downward can push the slider  230  to move downward, and the slider  230  moving downward can push the driving-force receiving member  210  to contract inward relative to the flange  270 . Therefore, when the driving-force receiving member  210  is in the contraction position, during the mounting process of the toner cartridge b, the driving-force receiving member  210  may not structurally interfere with the drive unit  900 , and there may be a gap H 3  between the top of the driving-force receiving member  210  and the bottom of the drive unit  900 . When the toner cartridge b is correctly mounted into the electronic imaging device P along the toner cartridge guide rail F 100 , the driving-force receiving member  210  may be approximately coaxial with the drive unit  900 . As the toner cartridge b is mounted, the pressure receiving element  221  may be moved to the rear end F 100   b  of the toner cartridge guide rail F 100  and no longer under pressure. As shown in  FIG. 35  and  FIG. 36 , the connecting part  260  may be pushed by the elastic force released from the elastic element  250 , and the driving-force receiving member  210  may be pushed by the connecting part  260  to protrude outward to engage with the drive unit  900 . As the driving-force receiving member  210  protrudes outward, the slider  230  and pressing element  220  that are engaged with the driving-force receiving member  210  may also be slid outward to the position before the slider  230  and the pressing element  220  are pressed. 
     When the cove P 1  is closed after the toner cartridge b and the photosensitive assembly a are correctly mounted into the electronic imaging device P, the drive unit  900   a  may protrude out along the rotation axis of the drive unit  900   a  and may be in contact and engaged with the driving element a 110  of the photosensitive assembly a. Simultaneously, the driving motor M 1  can drive the drive unit  900  and the drive unit  900   a  to rotate. The driving-force receiving member  210  can receive the rotation driving force from the drive unit  900  and transmit the rotation driving force to the flange  270 . The flange  270  can transmit the driving force to the gear  35  for driving the operation of developing unit  30 . The drive unit  900   a  may drive the driving element a 110  to rotate for driving the photosensitive unit  10  to operate. 
     In addition, after the toner cartridge b and the photosensitive assembly a are mounted in the electronic imaging device P, the toner cartridge b and the photosensitive assembly a can be supported and positioned by the toner cartridge guide rail F 100  and the photosensitive assembly guide rail F 200 , respectively. In the mounting process of the toner cartridge b, a locating column b 21  disposed at the front end of the side panel b 2  first may abut against the stopper F 110  and press down on the stopper F 110 , so that the mounting process of the toner cartridge b along the toner cartridge guide rail F 100  can be continued. After the toner cartridge b is correctly mounted, the locating column b 21  may be moved to the front end of the toner cartridge guide rail F 100  and no longer press the stopper F 110 . The stopper F 110  may be moved upward by the elastic force and retuned to a position where the stopper F 110  is not pressed, as shown in  FIG. 35 . Thus, the stopper may have certain elastic force to prevent the backward movement of the locating column b 21 , so that the entire toner cartridge b can be positioned on the toner cartridge guide rail F 100  to prevent the developing quality being affected by the shaking of the toner cartridge b during the developing operation. 
     Displacement Mode of the Pulling Part: Separation Process of the Photosensitive Unit  10  and the Developing Unit  30   
     As viewed from a side of the toner cartridge b or from axial direction of the driving-force receiving member  210 ,  FIG. 37  schematically shows the photosensitive unit  10  is rotated and engaged with the developing unit  30  to perform developing operation, i.e., the toner being transmitted from the developing chamber b 100  and printed on a paper S through the photosensitive unit  10  and the developing unit  30 . In the electronic imaging device P, the driving motor M 1  may simultaneously drive both of the drive unit  900  and driving nit  900   a  to rotate. Thus, when the developing operation is not running or the self-inspection of the electronic imaging device P is executing, the photosensitive unit  10  may need to be separated from the developing unit  30  by a certain distance, preventing the toner from being transmitted to the photosensitive unit  10  when the developing operation is not performed, therefor, the toner can be prevented from being wasted. 
     During the developing operation, the locations of the drive unit  900  and the drive unit  900   a  of the electronic imaging device P may be relatively fixed (i.e., a planar movement cannot be performed). Therefore, to separate the photosensitive unit  10  from the developing unit  30 , it may be necessary to at least separate drive unit  900  from the driving-force receiving member  210  that is engaged with the drive unit  900 . As shown in  FIG. 38  and  FIG. 39 , when the electronic imaging device P is not executing the developing operation or the self-inspection operation, the pulling part F 300  that is disposed below the toner cartridge guide rail F 100  can be triggered to be moved. At the bottom of the toner cartridge b, the cartridge action part b 4  may be disposed in front of the control mechanism  600 . Therefore, when the pulling part F 300  is moved backward (i.e., moved toward the rear end of the developing chamber b 100  of the toner cartridge b), the pulling part F 300  with a hook-shaped structure may act on the control mechanism  600 . The pulling part F 300  may drag control action part  620  of the control mechanism  600 , so that the driving-force receiving member  210  may be contracted inward relative to the flange  270  to be separated from the drive unit  900 . (The process of the driving-force receiving member  210  being controlled by the control mechanism  600  to contract, can refer to the structure and process of the Control Mode 1/Control Mode 2/Control Mode 3 of the control mechanism  600 , and is not elaborated herein.) 
     As described above, only the separation of driving-force receiving member  210  of the drive unit  900  is achieved, but the separation of photosensitive unit  10  and the developing unit  30  is not completed. Therefore, the pulling part F 300  which is dragging (hooked on) the control action part  620  may still need to be further moved backward to act on the cartridge action part b 4 . As shown in  FIG. 40 a    and  FIG. 40 b   , when the pulling part F 300  is acting on the cartridge action part b 4 , the pulling part F 300  can also simultaneously drag (hook on) the cartridge action part b 4  and the control mechanism  600 . The toner cartridge b is relatively positioned on the toner cartridge guide rail F 100 . For example, as the pulling part F 300  continuously moves, the pulling part F 300  drags the cartridge action part b 4  to move the toner cartridge b because the toner cartridge b has been relatively positioned on the toner cartridge guide rail F 100 . Therefore, when the toner cartridge b is dragged, the toner cartridge b can be rotated along with the toner cartridge guide rail F 100  around the rotation point F 101  of the toner cartridge guide rail F 100 . In this case, the driving-force receiving member  210  and the drive unit  900  can be separated. Therefore, during the rotation process of the toner cartridge b and the toner cartridge guide rail F 100 , the driving-force receiving member  210  may not structurally interfere with the relatively fixed drive unit  900 . The locating column b 21  of the toner cartridge b can also be stopped by the elastic stopper F 110 , so that the entire toner cartridge b can be positioned on the toner cartridge guide rail F 100 . Therefore, during the rotation process of the toner cartridge b and the toner cartridge guide rail F 100 , the toner cartridge b is not easily to be shaken due to being detached from the toner cartridge guide rail F 100  under an action of a pulling force. 
       FIG. 41  schematically shows the photosensitive unit  10  being separated from the developing unit  30  with a gap G between each other, after the cartridge action part b 4  and the control mechanism  600  are dragged by the pulling part F 300 . After the developing operation or the system self-inspection of the electronic imaging device P is completed, the driving motor M 1  may continue to drive the drive unit  900  and the drive unit  900   a  to rotate for a certain time, and the drive unit  900   a  may continue to drive the driving element a 110  to rotate, while the drive unit  900  may be disengaged with the driving-force receiving member  210 . Therefore, the driving-force receiving member  210  may not drive the developing unit to operate, so that when the developing operation is not performed, the toner can be prevented from wasting. Further, the separation of the photosensitive unit  10  from the developing unit  30  can prevent the contact abrasion that occurs when the developing operation is not performed. 
     In addition, driven by the pulling part F 300 , the toner cartridge b can be rotated, so that the toner cartridge guide rail F 100  can be rotated clockwise relative to the photosensitive assembly guide rail F 200 , and the signal that the trigger switch SW 1  is turned on can be generated. 
     Displacement Mode of the Pulling Part: Contacting Process of the Photosensitive Unit  10  and the Developing Unit  30   
     When the cartridge action part b 4  and the control mechanism  600  are not dragged by the pulling part F 300  to return to the position before the displacement, the pulling part F 300  may need to be moved in the opposite direction to return to the position before displacement. That is, the pulling part F 300  may need to be moved away from the rear end of the developing chamber b 100 , and at this time, and the pulling part F 300  may not act on the cartridge action part b 4 . As shown in  FIG. 42 , the traction element F 120  at the front end of the toner cartridge guide rail F 100  may generate a traction force to drag the toner cartridge guide rail F 100  to move toward the photosensitive assembly guide rail F 200  and return to the initial position before rotation. The toner cartridge b that is supported and positioned by the toner cartridge guide rail F 100  may also be moved toward the photosensitive assembly a that is supported and positioned by the photosensitive assembly guide rail F 200 , and the photosensitive unit  10  may be reconnected to the developing unit  30 . When the pulling part F 300  is further moved in the opposite direction till the pulling part F 300  does not act on the control mechanism action part  620  of the control mechanism  600 , the elastic force released by the elastic element  250  of the flange  270  can cause the driving-force receiving member  210  to protrude outward and engage with the drive unit  900  again. When the above operation procedures are completed, each part may return to the position before the pulling part F 300  is triggered to act, and the developing operation in the electronic imaging device P can be resumed. 
     During the process that the photosensitive unit  10  is connected to and separated from the developing unit  30 , as shown in  FIG. 40 a   , the toner cartridge guide rail F 100  and the toner cartridge b may be rotated together as a whole. Therefore, when the pulling part F 300  is acting on the toner cartridge b, the toner cartridge b may not move relative to the toner cartridge guide rail F 100 , and the pressure receiving element  221  may not be abutted against and pressed downward by the rear end F 100   b  of the toner cartridge guide rail F 100 . During the process that the photosensitive unit  10  is connected to and separated from the developing unit  30 , the axial contraction of the driving-force receiving member  210  may be controlled by the control mechanism  600  under the action of the pulling part F 300 . The contraction movement of the driving-force receiving member  210  may not be affected due to the pressure receiving element  221  being abutted against and pressed by the rear end F 100   b  of the toner cartridge guide rail F 100 . Therefore, it may not be affected that the driving-force receiving member  210  engaging with and disengaging from the drive unit  900 . 
     In addition, by retracting the action of the pulling part F 300 , the toner cartridge guide rail F 100  may be rotated counterclockwise relative to the photosensitive assembly guide rail F 200  by the traction element F 120 , and the signal that the trigger switch is turned off may be generated. 
     Displacement Mode of the Pulling Part: Unmounting/Removal of the Toner Cartridge and the Photosensitive Assembly 
     As shown in  FIG. 43 , the process of removing the toner cartridge b from the electronic imaging device P can refer to the process of mounting the toner cartridge b into the electronic imaging device P, and can be an opposite operation of mounting the toner cartridge b into the electronic imaging device P. The toner cartridge b can be removed from the electronic imaging device P along the toner cartridge guide rail F 100  in the X2 direction that is opposite to mounting direction. The pressure receiving element  221  of the drive assembly  200  may abut against the rear end F 100   b  of the toner cartridge guide rail F 100 , as the toner cartridge b is moved along the unmounting direction. The rear end F 100   b  may press the pressure receiving element  221  to move downward in the Y2 direction and drive the driving-force receiving member  210  to contract inward, so that the driving-force receiving member  210  can be disengaged with the drive unit  900 . Therefore, when the toner cartridge b is removed from the electronic imaging device P, a structural interference due to the driving-force receiving member  210  tightly engaged with the drive unit  900  may not occur, so that it is not difficult to unmount the toner cartridge b. When the toner cartridge b is completely removed from the electronic imaging device P, the front end F 100   a  of the toner cartridge guide rail F 100  may not press the pressure receiving element  221  of the drive assembly  200 . Therefore, because of the elastic force of the elastic element  250 , the pressure receiving element  221  and the driving-force receiving member  210  can protrude outward and return to the initial position before being pressed. 
     In addition, to make the removal of the toner cartridge b from the electronic imaging device P more smoothly and effortlessly, the driving-force receiving member  210  can be contracted inward because of the rear end of the toner cartridge guide rail according to Exemplary Embodiment I of the present disclosure. For example, as shown in  FIG. 44 , when the toner cartridge b is removed from the electronic imaging device P along the X2 direction (the unmounting direction) after the developing operation is completed, the drive unit  900  may still be tightly engaged with the driving-force receiving member  210 . Therefore, the driving-force receiving member  210  may be difficult to be moved along the unmounting direction, while the flange  270  and the end cap  290  can be moved relative to the driving-force receiving member  210 . When the driving-force receiving member  210  is relatively fixed in the unmounting direction due to the tight engagement, because of the movement of the driving-force receiving member  210  along the unmounting direction, the inclined sliding surface  291  of the driving-force receiving member  210  can generate the compression force F 2  and press on the inclined sliding surface  231  of the slider  230  to drive the slider  230  to contract inward. The driving-force receiving member  210  that is fixed relative to the slider  230  can also be moved downward as the slider  230  is contracted. In addition, during the contraction of the slider  230 , the pressing element  220  may also be pressed by the slider  230  to contract inward. Because of the sliding surface  294  of the end cap  290 , the sliding surface  224  of the pressing element  220  can be slid inward and kept vertical. Through the cooperation of the pressing element  220  and the slider  230 , the slider  230  and the driving-force receiving member  210  can be fixed and cooperate to keep the driving-force receiving member  210  vertical when the driving-force receiving member  210  is contracted inward. While moved, the rotation axis of driving-force receiving member  210  may be approximately coaxial or parallel to the rotation axis of the flange  270 . Thus, through the inclined sliding surface  291  of the end cap  290  compressing on the inclined sliding surface  231  of the slider  230 , the driving-force receiving member  210  can contract inward relative to the end cap  290  and disengage with the drive unit  900   
     When the toner cartridge b is removed from the electronic imaging device P, the pressing element  221  of drive assembly  220  may be pressed by the rear end F 100   b  of the toner cartridge guide rail F 100  so that the driving-force receiving member  210  can be contracted inward axially. The inclined sliding surface  291  of the end cap  290  may press on the inclined sliding surface  231  of slider  230 , so that the driving-force receiving member  210  can be contracted inward axially. Because of the above two contraction movement, it may be easier for the driving-force receiving member  210  to achieve axially disengagement after the driving-force receiving member  210  is tightly engaged with the drive unit  900 , which can prevent the structurally interference when the driving-force receiving member  210  is disengaged from the drive unit  900 . 
     Similarly, when the cover P 1  is reopen, the drive unit  900  may be contracted inward along the rotation axial direction thereof to be disengaged from the drive unit  900   a  of the photosensitive unit a, so that the photosensitive assembly a can be easily removed from the photosensitive assembly guide rail F 200 . 
     The cartridge action part b 4  of the toner cartridge b and the control mechanism  600  may be disposed as one in front of another, therefore, during the photosensitive unit  10  being separated from the developing unit  30 , the pulling part F 300  may first act on the control mechanism  600 , so that the driving-force receiving member  210  can be contracted inward and separated from the drive unit  900 . Then the pulling part F 300  may act on the cartridge action part b 4 , so that the toner cartridge b can be rotationally separated from the photosensitive assembly a. There may be a certain timing difference between the pulling part F 300  acting on the control mechanism and the pulling part F 300  acting on the cartridge action part b 4 . When the pulling part F 300  stops acting and returns to the initial position, the pulling part F 300  may first stop acting on the cartridge action part b 4  and then stop acting on the control mechanism  600 . 
     Exemplary Embodiment II 
     The toner cartridge b and the photosensitive assembly a described in exemplary Embodiment I are mutually independent, whereas, the toner cartridge b can also be connected to the photosensitive assembly a. As shown in  FIG. 45 , a connecting arm b 3   a  with a hole b 3  may be disposed on each of the side panel b 1  and b 2  of two sides of the toner cartridge b. The connecting arm b 3   a  may include a locating column b 22 . The connecting arm b 3   a  on the side panels b 1  and b 2  can extend into the two side ends of photosensitive chamber a 100  of the photosensitive assembly a. The top end of the elastic element a 4  may abut against the inner wall of photosensitive chamber a 100  and the bottom end of the elastic element a 4  may be inserted on the locating column b 22 . Through a pair of the connecting part a 3  passing through positioning holes at two sides of the photosensitive chamber a 100  and the hole b 3  of the developing chamber b 100 , the toner cartridge b can be connected to the photosensitive assembly a. In addition, because of the elastic force of the elastic element a 4 , the toner cartridge b can achieve a certain amount of swinging relative to the photosensitive assembly a. 
     As shown in  FIG. 46  and  FIG. 47 , the process of the photosensitive unit  10  being separated from and in contact with the developing unit  30  is similar to that described in Exemplary Embodiment I. When the toner cartridge b and the photosensitive assembly a are mounted into the electronic imaging device P, under the action of the pulling part F 300  on the control mechanism  600  and the cartridge action part p 4 , the toner cartridge b can be rotated around the rotation point (the position of hole b 3 /connecting part a 3   b   22 ) relative to the photosensitive assembly, so that the photosensitive unit  10  can be separated from the developing unit  30 . When the pulling part F 300  stops acting on the control mechanism  600  and the cartridge action part b 4 , the toner cartridge b can be rotated by the elastic force released from the elastic element a 4 , and the photosensitive unit  10  can be in contact with the developing unit  30  again. 
     Therefore, the connecting structure of the toner cartridge b and the photosensitive assembly a according to Exemplary Embodiment II can be used as an alternative to the structure of the rotatable toner cartridge guide rail F 100  of the electronic imaging device P described in Exemplary Embodiment I. The structure of some parts not shown according to Exemplary Embodiment II can refer to structure of the parts according to Exemplary Embodiment I and is not elaborated here. 
     Exemplary Embodiment III 
     Due to a matching mechanism (the pressing element  220  and the slider  230 ) of the drive assembly  200  according to the Exemplary Embodiment I/Exemplary Embodiment II, the driving-force receiving member  210  can be extended and contracted along the rotation axis thereof relative to the flange  270  or the end cap  290  to be engaged with and disengaged from the drive unit  900 . The matching mechanism can also be substituted by the following structure of the driving-force receiving member  210  to achieve a similar function and application. 
     As shown in  FIG. 48 , the claw  211  disposed at the upper end of the driving-force receiving member  210  can be tilted or swung relative to the driving-force receiving member  210 , i.e., the center line of the claw  211  may be tilted to a certain angle relative to the rotation axis of the driving-force receiving member  210 . In some embodiments, the tilted angle can be between 5° and 65°. The outer surface of the claw  211  may include a smooth curved transition. The claw  211  may also include an elastic member  810  (a rubber band or a tension spring). One end of the elastic element  810  may be connected to the claw  211 , and the other end may be connected to the driving-force receiving member  210 . When the claw  211  is not pressed by an external force, the claw  211  can be kept vertical. The claw  211  can be pressed downward by the external force to tilt. Around the pair of the claw  211  at the upper end of the driving-force receiving member  210 , an outward inclined surface  212  may be disposed outward, and an inward inclined surface  213  may be disposed inward. The outward inclined surface  212  and the inward inclined surface  213  can be constructed by a certain curved surface and an arc surface. 
       FIG. 49  and  FIG. 50  schematically show a contacting engagement of the drive assembly  200  of the toner cartridge b with the drive unit  900 . Because of configuration of the outward inclined surface  212 , when the driving receiving member  210  abut against the drive unit  900 , the semicircular structure of a bottom  912  of the drive unit  900  can directly press on the swingable claw  211  or the outward inclined surface  212 , and the claw  211  can incline inward and/or generate a downward compression force F 2  to drive the driving-force receiving member  210  to contract inward along the Y2 direction, avoiding rigid structural interference with the drive unit  900 . When the drive assembly  200  is continuously moved till the driving-force receiving member  210  is coaxial with the drive unit  900 , as shown in  FIG. 51 , the bottom end  912  of the drive unit  900  may not abut against the claw  211  or the outward inclined surface  212 . The elastic force released by the elastic element  250  can push the driving receiving force  210  to protrude outward along the Y1 direction, and to be in contact and engaged with the drive unit  900  to receive the driving force. During the process of the driving receiving member  210  protruding outward, there may be certain possibility that the claw  211  can abut against a drive column  910 , which may cause that the driving-force receiving member  210  is not completed engaging with the drive unit  900 . However, as the drive unit  900  is driven by the driving motor M 1  to rotate, the drive column  910  may be rotated to avoid the claw  211 . Therefore, when the interference disappears, the driving-force receiving member  210  can continue to protrude outward to complete engagement with the drive unit  900 . 
     During the process that the photosensitive unit  10  is separated from the developing unit  30  or the toner cartridge b is removed or unmounted from the electronic imaging device P according to Exemplary Embodiment I/Exemplary Embodiment II, as shown in  FIG. 52 , when the driving-force receiving member  210  is disengaged from the drive unit  900 , the drive unit  900  may be relatively stationary. During the disengaging movement of the driving-force receiving member  210 , the claw  211  and the inward inclined surface  213  may be abutted against and pressed by a semicircular structure at the bottom of the drive unit  900 , so that the claw  211  can inward tilted and/or generate downward compression force F 2 , causing the entire driving-force receiving member  210  to contract inward along the Y2 direction to avoid the rigid structural interference with the drive unit  900 . When the driving-force receiving member  210  is completely disengaged from the drive unit  900 , the driving-force receiving member  210  may be returned to the initial position by the elastic force of the elastic element  250  and the claw  211  may be returned to an upright state before the compression by the elastic force of the elastic element  810 . 
     According to Exemplary Embodiment III, because of the extension-contraction function of the entire driving-force receiving member  210  and the relatively swingable claw  211 , as well as the cooperation of the outward inclined surface  212  with the inward inclined surface  213 , the toner cartridge b can be mounted into and removed from the electronic imaging device P. The photosensitive unit  10  can be disengaged from and engaged with the developing unit  30  of the toner cartridge b in the electronic imaging device P. The driving-force receiving member  210  can realize the operation of engagement with and disengagement form the drive unit  900 . According to Exemplary Embodiment III, it may not be necessary to add the control mechanism  600  or drive assembly  200  described in the Exemplary Embodiment I/Exemplary Embodiment II to the toner cartridge b. 
     Exemplary Embodiment IV 
     As shown in  FIG. 53 , the connecting member  216  of the driving-force receiving member  210  may further include a resetting part  216   c . The resetting member  216   c  may include an elliptical structure or a non-circular cross-section (shown as cross-section B-B). In addition, the end cap  290  or the side panel b 2  may include a resetting part  291 , and the resetting part  291  may be an elastic metal ring, a rubber band, a torsion spring and a magnet, as shown in  FIG. 54 a    and  FIG. 54   b.    
     The resetting mechanism composed by the resetting part  291  and the resetting member  216   c  of the driving-force receiving member  210  can reposition the claw  211  of the driving-force receiving member  210 . The resetting member  216   c  can be applied with an elastic force by the resetting part  291  to rotate, and the rotating resetting member  216   c  can drive the claw  211  to rotate. As shown in  FIG. 55 , through the resetting mechanism, the claw  211  of the driving-force receiving member  210  can realize that one claw  211   a  is higher than the other claw  211   b  relative to the mounting direction X. If viewed in the mounting direction X, the distance H 4  between the two claws ( 211   a  and  211   b ) may be greater than the outer cylindrical width H 5  of the drive unit  900 . Even if the claw  211  according to Exemplary Embodiment IV cannot be swung or tilted relative to the driving-force receiving member  210 , because the distance between the claw  211   a  and the claw  211   b  can accommodate the outer cylindrical width of the drive unit  900 , when the driving-force receiving member  210  is engaging with the drive unit  900 , the outward inclined surface  212  of the driving-force receiving member  210  can be abutted against and pressed by bottom  912  with the semicircular structure of the drive unit  900  to contract inward relative to the flange  270 , so that the interference with the drive unit  900  can be avoided (referring to  FIG. 50 ). During the process of the claw  211  moving along the direction X, the claw  211  may not abut against the drive column  910  of the drive unit  900 , therefore the contacting engagement is not affected, as shown in  FIG. 56 . 
     The structure according to Exemplary Embodiment IV can be used in combination with the structure of the toner cartridge b according to Exemplary Embodiment I/Exemplary Embodiment II/Exemplary Embodiment III. 
     Exemplary Embodiment V 
     According to Exemplary Embodiment I/Exemplary Embodiment II/Exemplary Embodiment III/Exemplary Embodiment IV, the function achieved by the pulling part F 300  acting on the control action part  620  and the cartridge action part b 4  can also be achieved by directly using the cartridge action part b 4 . That is, the driving-force receiving member  210  can be controlled by the control mechanism  600  so that the driving-force receiving member  210  can be extended and contracted relative to the flange  270 . The toner cartridge b in the electronic imaging device P can be rotated relative to the photosensitive assembly a, so that the developing unit  30  can be separated from the photosensitive unit  10 . 
     As shown in  FIG. 57 , different from Exemplary Embodiment I to Exemplary Embodiment IV, a barrier wall b 2   b  rather than the cartridge action part b 4  disposed on the side panel according to the present exemplary embodiment. The barrier wall b 2   b  may be disposed on the movement track of the control action part  620  and can abut against the control action part  620 . Therefore, the control action part  620  can achieve all functions of the cartridge action part b 4  according to Exemplary Embodiment I to Exemplary Embodiment V. 
     As shown in  FIG. 58 , referring to Control Mode 1 of the control mechanism according to Exemplary Embodiment I, when the pulling part F 300  is moved backward, the pulling part F 300  may first act on the control mechanism  600 . The pulling part F 300  may drag the control action part  620  of the control mechanism  600 , so that the driving-force receiving member  210  can be extended and contracted relative to the flange  270  to be separated from the drive unit  900 . As the pulling part F 300  is further moved backward, the control action part  620  can be dragged by the pulling part F 300  to move along a designated path and be contact with the barrier wall b 2   b  of the side panel b 2 . Because the barrier wall b 2   b  may be fixed to the side panel b 2 , the control action part  620  can abut against the barrier wall b 2   b , so that the pulling force of pulling part F 300  can be converted to a pushing force on the barrier wall b 2   b , and the pushing force can push the side panel b 2 , causing the toner cartridge b to rotate relative to the photosensitive assembly a and being separated from the photosensitive assembly a, as shown in  FIG. 41 . 
     Similar to Exemplary Embodiment I to Exemplary Embodiment IV (the process of the photosensitive unit  10  contacting the developing unit  30 ), when the pulling part F 300  is returned the position before displacement, the control action part  620  may first retract the pushing force on the barrier wall b 2   b , as the pulling direction F 300  is moved in the opposite direction. As the toner cartridge b is rotated, the developing unit  30  can contact the photosensitive unit  10  again. Then the pulling part F 300  may further move backward, so that the pulling part F 300  cannot act (hook) on the control action part  620  of the control mechanism  600 . Because of the elastic force released by the elastic element  250 , the driving-force receiving member  210  can protrude out and reengage with the drive unit  900 . 
     Therefore, according to Exemplary Embodiment V, the function of the above embodiments can also be achieved by the control action part  620  in contact with the barrier wall b 2   b . That is, when the pulling part F 300  is triggered to act on the control action part  620 , the driving-force receiving member  210  can be first inward contracted. Then the toner cartridge b may be rotated relative to the photosensitive assembly a, so that the photosensitive unit  10  can be separated from the developing unit  30 . When the pulling part F 300  retracts action, the above action of the above parts can be repeated reversely. 
     In addition, a buffer layer, such as a sponge, a felt or a short spring, may be disposed on a contacting surface between the control action part  620  and the barrier wall b 2   b , so that there can be a buffer when the control action part  620  is in contact with the barrier wall b 2   b.    
     Exemplary Embodiment VI 
     According to Exemplary Embodiment VI, the main difference from the above Exemplary Embodiment I to Exemplary Embodiment V, is the configuration of the cartridge action part b 4 . The structure of the drive assembly  200  may refer to the structure of the drive assembly described in Exemplary Embodiment I to Exemplary Embodiment V and is not be elaborated here. 
     As shown in  FIG. 59 , sliders b 1   c  and b 2   c  may be disposed at the outer side of the side panels b 1  and b 2 , respectively. The side panels b 1  and b 2  may disposed at sides of the developing chamber b 100  of the toner cartridge b. A protrusion b 2   c   1  may be disposed at the inner side of the slider b 2   c , and a chute b 2   d   1  may be disposed on the surface of the side panel b 2 . Because of the protrusion b 2   c   1  cooperating with the chute b 2   d   1 , the slider b 2   c  can be slid on the side panel b 2  along a direction that is perpendicular to the axial direction of the developing unit  30 . A cartridge action part b 4  may be disposed at the bottom of the slider b 2   c , and a locating column b 21  may be disposed on the side surface of the slider b 2   c . (The slider b 1   c  on the other side panel b 1  may also have basically the same structure and the function of the b 2   c .) In addition, a positioning element b 120  may be disposed on the surface (upper) of the developing chamber b 100 . The positioning element b 120  may be outward convex cantilever, and a locating column b 121  may be disposed at the front end of the positioning element b 120 . The rear end of the developing chamber b 100  may include a pushing element b 110  that protrudes toward the chamber back of the developing chamber b 100 . The pushing element b 110  may be an elastic protrusion, e.g. a material with certain elastic amount, including elastic sponges, springs, plastic blocks, and magnets, etc. Through the positioning element b 120  and the pushing element b 110 , during the mounting process of the toner cartridge b into the electronic imaging device P, the toner cartridge b can be relatively positioned to or abutted against the relatively fixed internal structure of the electronic imaging device P. Therefor the toner cartridge b can be prevented from being shaken by an external force during the developing operation. 
     As shown in  FIG. 60  and  FIG. 61 , the slider b 2   c  can be slid in the X2 direction relative to the side panel b 2  and the developing chamber b 100  (i.e., can be moved toward the rear end of the developing chamber b 100 ), and simultaneously, drive the cartridge action part b 4  and the locating column b 21  of the slider b 2   c  to move. 
     As shown in  FIG. 62  and  FIG. 63 , a resetting part  810  (spring or tension spring) may also be disposed between the slider b 1   c  and the side panels b 1 , and between the slider b 2   c  and the side panel b 2 , so that when no external force is exerting on the sliders b 1   c , b 2   c , the slider b 1   c  and b 2   c  can be located at the front end of the toner cartridge b. That is, compared to the sliders b 1   c  and b 2   c  that are slid by an external force, when the sliders b 1   c  and b 2   c  can be located closer to the developing unit  30  before the external force is applied. 
     When the sliders b 1   c  and b 2   c  are slid by a force, the side panels b 1  and b 2  may be stationary relative to the developing chamber b 100  and the driving-force receiving member  210 . 
     As shown in  FIG. 64 , after the toner cartridge b is mounted in the electronic imaging device P and supported by the toner cartridge guide rail F 100 , (referring to the mounting process in Exemplary Embodiment I) the positioning element b 120  of the toner cartridge b may be relatively positioned on the photosensitive assembly guide rail F 200 . The two locating columns b 121  of the positioning element b 120  can sandwich the upper frame structure of the photosensitive assembly guide rail F 200 , so that the developing chamber b 100  and the side panels b 1  and b 2  at both sides can be relatively fixed by positioning and fixing the positioning element b 120 . The pushing element b 110  at the rear end of the toner cartridge b may abut against the front frame structure F 400  of the electronic imaging device P. Through the elastic pushing force generated after the abutment, the developing chamber b 100  and the side panels b 1  and b 2  can be moved in the direction toward the photosensitive assembly a, and the developing unit  30  of the developing chamber b 100  can be kept in contact with the photosensitive unit  10 . The slider b 2   c  of the side panel b 2  can be supported at the toner cartridge guide rail F 100  by the locating column b 21 . Because of the above positioning, the toner cartridge b can perform developing operation in a relatively stationary status, as shown in  FIG. 65 . 
     As shown in  FIG. 64  and  FIG. 66 , through the sliding structure of the slider b 2   c  and the side panel b 2 , the inspection operation can be performed by the inspection device PD 1  of the electronic imaging device P. When the pulling part F 200  is triggered to move, the pulling part F 300  can drag (hook on) the cartridge action part b 4  of the slider b 2   c . The slider b 2   c  can be moved backward in the X2 direction along with the movement of the pulling part F 300 . The backward displacement of the slider b 2   c  can also drive the toner cartridge guide rail F 100  to rotate. Finally, the pushing block F 103  of toner cartridge guide rail F 100  can touch the trigger switch SW 1 , so that the trigger switch can be turned on. When the force of the pulling part F 300  is retracted, the toner cartridge guide rail F 100  can be returned to the initial position before the rotation, and the trigger switch SW 1  can be turned off. 
     Different from the Exemplary Embodiment I to Exemplary Embodiment V, the slider b 2   c  according to Exemplary Embodiment VI can be slidably moved on the side panel b 2 , and the developing cartridge b 100  and the side panels b 1 , b 2  can be relatively positioned or abutted against by the positioning element b 120  and/or the pushing element b 110 . Therefore, the during the process that the toner cartridge is rotated by pulling part F 300  acting on or retracting action from the toner cartridge guide rail b 4 , the developing chamber b 100  can be kept in contact with the photosensitive unit  10 , and the driving-force receiving member  210  of the side panel b 2  may not be separated from but may be kept engaged with the drive unit  900 , and can drive the developing unit  30  to rotate constantly. 
     In addition, due to the constant contact of the developing unit  30  with the photosensitive unit  10 , the structure of the developing unit  30  may be configured as shown in  FIG. 67 . The developing unit  30  may include a cylinder  32 , and the cylinder  32  may include a magnetic core  22 . An elastic layer  31  having certain amount of elastic compression may be disposed at the outer layer of the cylinder  32  where the cylinder  32  is in contact with the photosensitive unit  10 . The elastic layer  31  may be coated with a developing coating. The presence of the elastic layer  31  can prevent the rigid contact between the developing unit  30  and the photosensitive unit  10  during continuous contact rotation, reducing the long-term contact abrasion therebetween, and extending the service lifetime of the development unit  30  and the photosensitive unit  10 . 
     The developing unit  30  with an elastic layer  31  according to Exemplary Embodiment VI can also be applied to the toner cartridge b described in Exemplary Embodiment I to Exemplary Embodiment V to increase the service lifetime of the developing unit  30 . 
     In addition, referring to Exemplary Embodiment II, the toner cartridge b and the photosensitive assembly a according to Exemplary Embodiment VI may also be configured as a mutually connected structure, so that the developing chamber b 100  of the toner cartridge b and the side panels b 1  and b 2  on both sides can be relatively positioned in the electronic imaging device P, i.e., these parts can be positioned by interconnecting with the photosensitive assembly a, and the auxiliary positioning of the positioning element b 120  or the pushing element b 110  may not be required. As shown in  FIG. 68 , the toner cartridge b may be coupled with the photosensitive assembly a via the connecting arm b 3   a  of the side panels b 1  and b 2 , and the connecting part a 3  can pass through the positioning hole on both sides of the photosensitive chamber a 100  and the hole b 3  of the developing chamber b 100  to connect the toner cartridge b with the photosensitive assembly a as an integral structure. An elastic element a 4  may be disposed between the toner cartridge b and the photosensitive assembly a. 
     As shown in  FIG. 69  and  FIG. 70 , the toner cartridge b can be relatively fixed and positioned in the electronic imaging device P by interconnecting with the photosensitive assembly a. The slider b 2   c  can be slidably moved relative to the toner cartridge b and the photosensitive assembly a. The slider b 2   c  can also abut against the elastic element a 4  between the toner cartridge b and the photosensitive assembly a to generate a downward compression force F 3 , which can act on the toner cartridge b. Through the rotation point (b 3 /a 3 ), the toner cartridge b can apply the downward compression force F 3  on the developing unit  30 , so that the developing unit  30  can be in contact with the photosensitive unit  10 . Therefore, through the connection between the developing unit  30  and the photosensitive unit  10 , the toner cartridge b can perform the developing operation after being relatively positioned by connecting to the photosensitive assembly a. 
     Exemplary Embodiment VII 
     According to Exemplary Embodiment VII, the main difference from the Exemplary Embodiment I to Exemplary Embodiment VI is about the structure and function of the cartridge action part b 4 . The cartridge action part b 4  can not only move the locating column b 21  relative to the side panel b 2  or the developing chamber b 100 , but also control the axial extension and contraction of the driving-force receiving member  210 . 
     As shown in  FIG. 70 a     1  to  FIG. 70 a     3 , one side of the developing chamber b 100  of the toner cartridge b may include a side panel b 2 , a base plate b 2   e  matching with the side panel b 2 , a side panel cover b 24 , a control mechanism  600 , a slider b 2   c , and a cartridge action part b 4 , a driving-force receiving member  210 , a slider  230 , a flange  270 , a driving force transmission element  274 , and a pressing element b 2   f . The side panel b 2  may include a first chute b 2   d   1 , a second chute b 2   d   2  and a through hole b 25 . The base plate b 2   e  may include a chute b 2   e   1 , a limiting element b 2   e   2  and a positioning hole. The control mechanism  600  may have a rod-shaped structure, the front end may have a fork-shaped structure with an inclined surface  631  at the inner side, and the rear end may include a protrusion  632 , as shown in  FIG. 70C . The slider  230  may include an inclined surface  231 . The slider b 2   c  may include a protrusion b 2   c   1  facing inward, a sliding block b 2   c   4  facing outward, and a chute b 2   c   2 . The front end of the slider b 2   c  may include a connecting hole b 2   c   3 , and the side surface of the slider b 2   c  may include a locating column b 21 , as shown in  FIG. 70 b   . The lower part (facing downward) of the cartridge action part b 4  may include a hook-shaped structure, and the upper part may include a sliding block b 42  and a protrusion b 41 . The shapes of the protrusion b 41 , the chute b 2   e   1 , the sliding block b 42 , the sliding block b 2   c   4 , the chute b 2   c   2 , the first chute b 2   d   1 , and the second chute b 2   d   2  may have a certain degree of curvature. 
     As shown in  FIG. 70 a     2  and  FIG. 70 a     3 , the assembly relationship between the parts described above may be as following. The connecting member of the driving-force receiving member  210  may pass through the slider  230  and is placed in the through hole b 25 . Through the connecting part  260 , the connecting member may be relatively fixed and connected to the driving force transmission element  274  disposed behind the side panel b 2 . The entire driving force transmission element  274  may be disposed in the flange  270 . The flange  270  may include an elastic element, which may be disposed between the driving force transmission element  274  and the base plate b 2   e . The protrusion b 2   c   1  of the slider b 2   c  may be slidably disposed at in first chute of the side panel b 2 . The sliding block may be also slidably disposed at the second chute b 2   d   2  of the side panel b 2 . One end of a resetting part  810  may be connected to the connecting hole b 2   c   3  at the front end of the slider b 2   c , and the other end of the resetting part  810  may be sleeved with a protrusion (not shown) at the inner side of the side panel b 2 . The sliding block b 42  of the cartridge action part b 4  can be slidably disposed in the chute b 2   e   1  of the base plate b 2   e . The protrusion b 41  can be slidably disposed in the chute b 2   c   2  of the slider b 2   c . A width L 4  of the protrusion b 41  may be smaller than a width L 5  of the chute b 2   c   2 . The pressing element b 2   f  can be slidably disposed at the limiting element b 2   e   2  of the base plate b 2   e . An elastic element  250  may be disposed between the pressing element b 2   f  and a barrier wall of the base plate b 2   e . The control mechanism  600  may be disposed on the recess at the outside of the side panel b 2 , and the elastic element  250  may be disposed between the control mechanism  600  and the barrier wall of the side panel b 2 . The fork-shaped structure at the front of the control mechanism  600  may include the connecting member of the driving-force receiving member  210 . The inclined surface  231  may abut against the inclined surface  631 . The side panel b 2  can be fixedly cover the base plate b 2   e , and the side panel cover b 24  can be fixed to the side panel b 2  and covers the control mechanism  600 . 
     After the above assembly is completed, during the interaction of the cartridge action part b 4  and the pulling part F 300 , through the cartridge action part b 4 , the locating column b 21  and the driving-force receiving member  210  can achieve the following movement process, i.e., the following displacements can be achieved. 
     (1) The initial position/the first position. When the cartridge action part b 4  is not subjected to an external force, that is, the pulling part F 300  exerts no force on the cartridge action part b 4 , as shown in  FIG. 70 d     1  to  FIG. 70 d     3 , the control mechanism  600  can be moved backward by the elastic force of the elastic element  250 . At this time, the elastic force of the elastic element  250  of the control mechanism  600  may be greater than the elastic force of the elastic element that provides the axial elastic force to the driving-force receiving member  210 . Therefore, the inclined surface  631  at the inner side of the frond end of the control mechanism  600  can press the inclined surface  231  of the slider  230  downward, so that the driving-force receiving member  210  can be kept contracted inward relative to the flange  270  and may not be engaged with the drive unit  900 . The resetting part  810  may also drag the cartridge action part b 4  in the initial position. Because the protrusion b 41  is in the chute b 2   c   2 , the slider b 2   c  may also be in the initial state/position under the traction force of the resetting part  810 . The protrusion  632  at the rear end of the control mechanism  600  can abut against the protrusion  641  at the front end of the cartridge action part b 4  to limit the position of the protrusion  641 , and as a result, the protrusion b 41  can be placed at the rear end of the chute b 2   c   2 . 
     (2) The backward displaced position/the second position. When the pulling part F 300  is moved backward to drag (hook on) the cartridge action part b 4 , as shown in  FIG. 70 e     1  and  FIG. 70 e     2 , the sliding block b 42  of the cartridge action part b 4  can be slid along the second chute b 2   d   2 . The entire cartridge action part b 4  can be slidably moved relative to the side panel b 2 , and the protrusion b 41  in the chute b 2   c   2  can simultaneously drive the slider b 2   c  to slide. The protrusion b 2   c   1  of the slider b 2   c  can be slid in the first chute b 2   d   1  of the side panel b 2 , i.e., driven by the cartridge action part b 4 , the entire slider b 2   c  can be slidably displaced relative to the side panel b 2 . It is possible to achieve a similar function to the function according to Exemplary Embodiment VI by the following movements. The cartridge action part b 4  can be dragged by the pulling part F 300 , so that the slider b 2   c  can be slid backward relative to the side panel b 2 . The locating column b 21  can be slid together with the slider b 2   c  to drive the toner cartridge guide rail F 100  to rotate. Finally, the trigger switch SW 1  can be touched by the pushing block F 103  of the toner cartridge guide rail F 100 , and the trigger switch SW 1  can be turned on, referring to  FIG. 66 . At this time, the driving-force receiving member  210  may be kept inward contracted relative to the flange  270 , and not engaged with the drive unit  900 . When the pulling part F 300  no longer acts on the cartridge action part b 4 , the cartridge action part b 4  can be driven by the traction force of the resetting part  810  to bring the slider b 2   c  together to return to the initial position/first position. 
     (3) The pushing position/third position. The protrusion b 41  can be slid in the chute b 2   c   2 , and in the initial/first position, the protrusion b 41  can be positioned at the rear end of the chute b 2   c   2 . When the cartridge action part b 4  is displaced (pushed) by the pulling part F 300 , as shown in  FIG. 70 f     1  and  FIG. 70   f   2 , the protrusion at the rear end of the pulling part F 300  can abut against the rear end of the hook-shaped structure of the cartridge action part b 4 . As the pulling part moves forward, the cartridge action part b 4  may be pushed by the pulling part to move forward. The pushing force can exert on the protrusion b 41  to push the protrusion  632  at the rear end of the control mechanism  600 , so that the entire control mechanism  600  can be moved forward. As shown in  FIG. 70 f     3 , as the control mechanism is pushed to move forward, the inclined surface  631  at the front end of the control mechanism  600  may not press the inclined surface  231  downward, and the driving-force receiving member  210  can be pushed by the elastic force released by the elastic element of the flange  270  to protrude outward and engage with the drive unit  900 . After the cartridge action part b 4  is pushed forward for a certain distance, the cartridge action part b 4  can abut against the pressing element b 2   f  and transmit the pushing force to the toner cartridge b through the elastic element  250  of the pushing element b 2   f . Therefore, under the action of the pushing force of the pulling part F 300 , the developing unit  30  of the toner cartridge b can be more closely in contact with the developing unit  10 , i.e., the developing unit  10  can be pushed by the pulling part F 300  to be in contact with the developing unit  10 . 
     The above operation process is as following. Compared to the cartridge action part b 4 , the slider b 2   c , and the locating column b 21   at  the initial position/first position, the cartridge action part b 4 , the slider b 2   c , and the locating column b 21  at the backward displaced position/second position may be further away from the driving-force receiving member  210  or the photosensitive unit  10 . That is the cartridge action part b 4 , the slider b 2   c , and the locating column b 21  may be moved away from the driving-force receiving member  210  or the photosensitive unit  10  by the backward movement of the pulling part F 300 . In the pushing position/third position, the driving-force receiving member  210  may protrude outward relative to the flange  270 ; while in the backward displaced position/second position or the initial position/first position, the driving-force receiving member  210  can be kept retracted inward relative to the flange  270 . 
     In addition, as shown in  FIG. 70 f     4  and  FIG. 70 f     2 , in the pushing position/third position, the rear end (i.e., the part that is abutted against by the protrusion of the rear end of the pulling part F 300 ) of the hook-shaped body of the cartridge action part b 4  may also include an elastic buffer element b 43  (obtained by pasting or second injection molding). The buffer element b 43  can be an elastic sponge or an elastic rubber and have certain buffering and over-limiting function. By the buffer element b 43 , when the rear end of cartridge action part b 4  is pushed by the pulling part F 300 , the cartridge action part b 4  can be prevented from damage or inaccurate positioning that may be caused by that the pulling part F 300  and the cartridge action part b 4  are compressed by each other or the pushing range of the pulling part F 300  exceeds the limit. 
     In addition, in the present embodiment, the claw  211  of the driving-force receiving member  210  may also be capable of tilting or swinging relative to the driving-force receiving member  210  as shown in  FIG. 48  to  FIG. 52 . 
     Exemplary Embodiment VIII 
     In the structure in which the toner cartridge b and the photosensitive assembly a are integrally connected with each other according to Exemplary Embodiment VI, it may be possible to simplify the internal structure. 
     As shown in  FIG. 71 , referring to the Exemplary Embodiment VI and Exemplary Embodiment II, a gear  15  may be disposed at one side of the photosensitive unit  10 , and the gear  15  of the photosensitive unit  10  can be matched and engage with the gear  35  of the developing unit  30 . Thus, the configuration of the drive assembly  200  can be omitted. After the toner cartridge b together with the photosensitive assembly a is mounted into the electronic imaging device P, the driving element a 100  of the photosensitive assembly a can be driven by the drive unit  900   a , the driving element a 110  may transmit the driving force for rotation to the gear  35  through the gear  15 , and the developing unit  30  can be moved by the gear  35 . Therefore, the photosensitive unit  10  and the developing unit  30  can be driven together to perform developing operation. 
     The toner cartridge b according to Exemplary Embodiment VIII may also include the slider b 2   c  described in Exemplary Embodiment VI. When there is no drive assembly  200 , the pulling potion F 300  can act on the slider b 2   c  to rotate the toner cartridge guide rail F 100 , so that the inspection process of the inspection device PD 1  in the electronic imaging device P can still be implemented. The implementation process can refer to the above embodiments and is not elaborated here. 
     In addition, according to above embodiments, as shown in  FIG. 72  and  FIG. 45 , viewed from the axial direction of the drive unit  900 / 900   a  of the electronic imaging device P (i.e., from the side of the electronic imaging device P), in the electronic imaging device P, a guide rail identification block F 250  may be disposed between the top of the toner cartridge guide F 100  and the top of the photosensitive module guideway F 200 . The guide rail identification block F 250  may be configured to block the erroneous mounting of the toner cartridge b and the photosensitive assembly a and prevent a user from mistakenly mounting the toner cartridge b into the photosensitive assembly guide rail F 200  or mounting the photosensitive assembly a into the toner cartridge guide rail F 100 , thereby preventing both guide rails from structural damage. The guide rail identification block F 250  may be integrally fixed with the photosensitive assembly guide rail F 200 , and can be disposed at both sides or one side of the photosensitive assembly guide rail F 200 . Therefore, as shown in  FIG. 72 , if the toner cartridge b and the photosensitive assembly b are connected to each other and integrally configured, a notch a 101  may be needed to be disposed at the side of the photosensitive assembly a or the toner cartridge. If viewed from the top of the toner cartridge b, the notch a 101  may be disposed between the photosensitive chamber a 100  and the developing chamber b 100  (i.e., between the rotation axis of the photosensitive unit  10  and the rotation axis of the developing unit  30 ), and on the side surface of the toner cartridge b. Therefore, when the user integrally mounts the toner cartridge b and the photosensitive assembly a into the electronic imaging device P, the notch a 101  can pass through the guide rail identification block F 250  at the top of the photosensitive assembly guide rail F 200  without being blocked, so that the toner cartridge b and the photosensitive assembly a can be mounted into the electronic imaging device P. 
     According to Exemplary Embodiment I to Exemplary Embodiment VIII, through the presence of the cartridge action part b 4 , the inspection of the toner cartridge b by the inspection device PD 1  in the electronic imaging device P can also be achieved, and the required inspection procedures can be completed. 
     According to Exemplary Embodiments I to Exemplary Embodiment VIII, as shown in  FIG. 73 , which is viewed from the top of the toner cartridge b, to enable the toner cartridge b to be easily unmounted (removed) from the electronic imaging device P, guide surfaces b 1   x  and b 2   x  can be disposed on the side panels b 1  and b 2  of the two sides of the toner cartridge b or disposed at the outer side of the slider b 1   c  and b 2   c  of the side panels b 1  and b 2 , respectively. The guide surfaces b 1   x , b 2   x  may be inclined or arcuate surfaces. On the side panel b 2  or the slider b 2   c  that is at the same end of the toner cartridge b as the driving-force receiving member  210 , the guide surface b 2   x  may be disposed at the rear end of the side panel b 2  or the slider b 2   c , i.e., disposed near the rear end of the toner cartridge. On the side panel b 1  and the slider b 1   c  at the other end of the toner cartridge, the guide surface b 1   x  may be disposed at the front end of the side panel b 1  or the slider b 1   c , i.e., disposed near the rotation axis of the developing unit  30 . There may be an angle R 1  between the guide surfaces b 1   x  and b 2   x  and the rotation axis of the developing unit  30 . In addition, in order to better achieve the function of the guide surfaces b 1   x  and b 2   x , at the developing chamber b 100 , the grabbing element b 120  of the toner cartridge b may be disposed on one side of the toner cartridge b that is away from the driving-force receiving member  210 . 
     As shown in  FIG. 74 , the toner cartridge b can be unmounted (removed) from the electronic imaging device P through the configuration of the guide surfaces b 1   x  and b 2   x  and the auxiliary configuration of the grabbing element b 120 . Even if there is some structural interference between the drive unit  900  and the driving-force receiving member  210 , the toner cartridge b can still be removed by tilting the toner cartridge b, and the drive unit  900  can be completely disengaged from the driving-force receiving member  210 . During the disengagement process of the drive unit  900  from the driving-force receiving member  210 , the rotation axis of the driving-force receiving member  210  or the developing unit  30  can be tilted relative to the rotation axis of the drive unit  900 / 900   a.    
     In the above embodiment, according to the structure of the toner cartridge guide rail F 100  inside the electronic imaging device P, the pressing element  221  of the drive assembly  100  may be pressed downward and the extension and the contraction of the driving-force receiving member  210  can be controlled by cooperation with a force transmission element  280 . As shown in  FIG. 75 , which is viewed in the direction from the side of the electronic imaging device P, the inner side of the toner cartridge guide rail F 100  may include a protrusion F 102 . The protrusion F 102  may include a rotation point F 101  of the toner cartridge guide rail F 100 . Referring to the mounting direction of the toner cartridge b, i.e. the X1 direction, a rear inclined surface F 102   b  may be disposed at the back side below the protrusion F 102 , while a front inclined surface F 102   a  may also be disposed at the front side. The front inclined surface F 102   a  and the rear inclined surface F 102   b  may be mirror-image configured relative to the center line of the protrusion F 102 . 
     As shown in  FIG. 76 , the force transmission element  280  may be disposed on the side panel b 2  and include a pressure receiving part  281  and a pushing element  282  (pushing rod). The bottom of the pressure receiving part  281  may include an buckle  281   d , and the pressure member  281  may pass through the buckle  281   d  and can be inserted into the chute b 23  at the surface of the side panel b 2  so that the pressure receiving part  281  can slide along the chute b 23 . Referring to the mounting direction of the toner cartridge b, i.e., the X1 direction, the front inclined surface  281   b  and the rear inclined surface  281   a  may be disposed above the pressure receiving part  281  and a down inclined surface  281   c  may be disposed below the pressure receiving part  281 . One end (the rear end) of the pushing element  282  may include a rear inclined surface  282   c  that abuts against the down inclined surface  281   c , and the other end (the front end) may include a front inclined surface  282   b  that abuts against the pressing element  221 . In addition, the bottom of the pushing element  282  may also include an undercut that is matched with the chute of the side panel b 2  (not shown, referring to the chute b 23  and the buckle  281   d ). 
     As shown in  FIG. 77 a    to  FIG. 77 d   , when the toner cartridge b is mounted in the mounting direction, i.e., the X1 direction, the front inclined surface  281   b  of the pressure receiving part  281  may first abut against the rear inclined surface F 102   b  of the protrusion F 102  to generate a downward pressing force F, which can press the pressure receiving part  281  to move downward. The down inclined surface  281   c  of the pressure receiving part  281  may also cooperate with and abut against the rear inclined surface  282   c  of the pushing element  282 , so that the pushing element  282  can be moved forward. The front inclined surface may press the pressing element  221 , so that the driving-force receiving member  210  can be contracted inward and prevented from structurally interfering with the drive unit  900  (referring to  FIG. 34 ). After the toner cartridge b is correctly mounted, the pressure receiving part  281  can pass over the protrusion F 102  as the toner cartridge b is mounted, and the front inclined surface  282   b  may not be pressed. Through an elastic force, the driving-force receiving member  210  can protrude outward and engage with the drive unit  900 , and the pressure receiving part  281  and the pushing element  282  can also be pushed by the elastic force to return to the position before being pressed. When the toner cartridge b is removed, the rear inclined surface  281   a  of the pressure receiving part  281  can abut against with the front inclined surface F 102   a  of the protrusion F 102 , and the driving-force receiving member  210  can be contracted inward and disengaged form the drive unit  900 . In addition, as shown in  FIG. 78 , the pressure receiving part  281  and the pushing element  282  of the force transmission element  280  can be substituted by a rotatable swinging rod. The swinging rod can be pressed to rotate around the rotation point  281   p  thereof. The front inclined surface  281   b  and the rear inclined surface  281   a  of one end (rear end) of the swinging rod, and front inclined surface  282   b  of the pressing element  221  at the other end (front end) of the swinging rod can refer to the above configuration and are not elaborated here. That is, when the force transmission element  280  is pressed to transmit the downward pressing force F, the action of the force transmission element can be a rotation movement or a translational movement. 
     Exemplary Embodiment IX 
     According to previous embodiments, the trigger switch SW 1  can be touched by the pushing block F 103  of the toner cartridge guide rail F 100  (of the inspection mechanism of the electronic imaging device), so that the inspection device PD 1  can perform inspection operation and generate the signal that the trigger switch SW 1  is turned on. Different from the inspection mode of previous embodiments, inspection mechanism according to Exemplary Embodiment IX is to inspect the toner cartridge b that is mounted in the electronic imaging device P through emitting and detecting of a detection light. 
     As shown in  FIG. 79 , the inner surface of the electronic imaging device P may include a light-emitting element LS 101  (e.g. a light emitting part of a light emitting diode (LED)), a light-receiving element LS 102  and an inspection device PD 2 . The inspection device may be configured to determine the detection light emitted from the light emitting element LS 101  is received by the light receiving element LS 102  and then generate a signal about the inspection is completed. 
     With reference to Exemplary Embodiment I to Exemplary Embodiment VIII, the toner cartridge b and the photosensitive assembly a according to the present embodiment may be integrally configured or independent form each other. Optionally, the toner cartridge b and the photosensitive assembly a may be integrally disposed according to Exemplary Embodiment IX. 
     The structure and function of the drive assembly  200  and the contact engagement and disengagement process of the drive assembly  200  and the drive unit  900  in Exemplary Embodiment IX can refer to the above embodiments and are not elaborated here. 
     Control Mode 1 of Translucent Element 
     As shown in  FIG. 80 a    and  FIG. 80 b   , the slider b 1   c  of the side panel b 1  may include a translucent element b 1   a . When the slider b 1   c  is slid relative to the side panel b 1  because of the pulling part F 300  acting on the cartridge action part b 4 , the translucent element b 1   a  can be moved along with the sliding of the slider b 1   c . One end (an upper end) of the translucent element b 1   a  may include a light-incident surface b 1   a   1 , and the other end (a lower end) may include a light-emitting surface b 1   a   2 . The translucent element may also include two inclined and opposite light-reflecting surfaces b 1   a   3  and b 1   a   4 , as shown in  FIG. 81 . 
     As shown in  FIG. 82 a   , after the toner cartridge b is mounted in the electronic imaging device P, the inspection device PD 2  can start the inspection of mounted toner cartridge b. When the pulling part F 300  does not drag the cartridge action part b 4  to cause the slider b 1   c  to undergo a sliding displacement, the light-emitting element LS 101  of the electronic imaging device P can correspond to the light incident surface b 1   a   1  of the translucent element b 1   a , and the light-receiving element LS 102  can correspond to the light-emitting surface b 1   a   2 . After emitted by the light-emitting element LS 101  to the light-incident surface b 1   a   1 , the detection light may be reflected by the light-reflecting surface b 1   a   3  and guided to the opposite light-reflecting surface b 1   a   4 . The detection light may be guided by the light-reflecting surface b 1   a   4  to transmit out through a light-emitting surface b 1   a   2 . Finally, the detection light can be detected by the light-receiving element LS 102 . The guiding path of the detection light in the translucent element b 1   a  may be a “U” type, and a received-signal can be generated by the inspection device PD 2 . When the pulling part F 300  drags the cartridge action part b 4  to cause the slider b 1   c  to undergo a sliding displacement, as shown in  FIG. 82 b    and  FIG. 82 c   , after the slider b 1   c  is displaced, the light-emitting element LS 101  cannot correspond to the light-incident surface b 1   a   1  of the translucent element b 1   a . Therefore, the detection light emitted by the light-emitting element LS 101  cannot illuminate on the light-incident surface b 1   a   1 , so that the light-receiving element LS 102  cannot receive the detection light and the inspection device PD 2  may generate an unreceived-signal. Thus, through the signal generated by the inspection device PD 2 , the electronic imaging device P can inspect whether the toner cartridge mounted by the user matches the electronic imaging device P. For example, if a signal generated is “received-unreceived” or “received-unreceived-received-unreceived”, the electronic imaging device P can automatically determine a matching toner cartridge is mounted by the user, the electronic imaging device P may display that the inspection procedure is completed, and the user can perform normal developing operation (printing). 
     Control Mode 2 of Translucent Element 
     In addition, as shown in  FIG. 83  to  FIG. 84 b   , the translucent element b 1   a  may also be disposed on the side panel b 1 , and the slider b 1   c  that can be slid relative to side panel b 1  may include a through hole b 1   b  that can correspond to the translucent element b 1   a . When the pulling part F 300  does not drag the cartridge action part b 4  to cause the slider b 1   c  to undergo a sliding displacement, the light-incident surface b 1   a   1  and the light-emitting surface b 1   a   2  of the translucent element b 1   a  can be exposed through the through hole b 1   b . Thus, the detection light emitted by the light-emitting element LS 101  can be reflected and guided by the translucent element b 1   a  to the light-receiving element LS 102  and the inspection can be completed. When the slider b 1   c  is moved by a force, at lease a part of the light-incident surface b 1   a   1  and/or the light-emitting surface b 1   a   2  can be covered and blocked by the base plate of the sider b 1   c . Thus, the detection light emitted from the light-emitting element LS 101  cannot illuminate on the light-incident surface b 1   a   1 , and the light-receiving element LS 102  cannot receive the detection light. Therefore, the Control Mode 2 of the translucent element can also achieve the same inspection function and the same defection effect as the Control Mode 1 of the translucent element. 
     In addition, to increase the inspection accuracy, the quantity of translucent element b 1   a  may also be two (the quantity of the through hole b 1   b  is two), and correspondingly, the electronic imaging device P may also include two sets of the light-emitting elements LS 101  and the light-receiving elements LS 102 . 
     In addition, as shown in  FIG. 85 , the inspection method according to Exemplary Embodiment IX may also be the following. A chip  830  may be disposed on the slider b 1   c , and correspondingly a contact unit (not shown) configured to be in contact with the chap  830  and obtain the chip information may be disposed at the electronic imaging device P. Through the pulling part F 300  acting on the slider b 1   c , the slider b 1   c  can be slid back and forth, so that connection between the chip  830  and the contact unit can be turned on and off, and the above similar inspection process can be completed.
