Since the extension of the chip contact 220 is inclined, that is, the free end 222 rotates and extends around the fixed end, and the elastic piece 221 is provided with a bump 223 for contacting the chip 310. The point of contact can be the side periphery of the bump 223 on the elastic piece 221 , thereby increasing the contact area between the chip contact 220 and the chip 310 , and ensuring that the chip contact 220 can be in good contact with the chip 310 . On the other hand, the chip contact 220 uses the elastic piece 221, and the elastic piece 221 itself has elastic force, which can be reset by its own elastic force after the pusher 210 returns, so that when the process box 300 is drawn out of the process box installation cavity 110, the process box Chip 310 and end caps of 300 are also not rubbed by chip contacts 220 . The free end 222 of the elastic piece 221 is folded to the side facing away from the protruding point 223. This setting makes the free end 222 of the elastic piece 221 guide the movement of the pusher 210, so that the pusher 210 moves to the bottom of the chip contact 220 ( As shown in Figure 7, the pusher 210 extends into the lower part of the chip contact 220), and then the elastic piece 221 is pushed out of the mounting hole 123, and the free end 222 of the elastic piece 221 is turned over to the side facing away from the bump 223 so that the turning of the elastic piece 221 The folded end forms an inclined surface, and the inclined surface of the free end 222 of the elastic piece 221 cooperates with the inclined surface 214 of the pusher 210 to reduce the sliding stroke of the pusher 210 .

As shown in Figure 12, the pusher 210 includes a sliding part 211, a pushing part 213 and a forcing part 212 connected to both ends of the sliding part 211, the trigger mechanism cooperates with the forcing part 212, and the pushing part 213 is located at the free end 222 of the chip contact 220.

The setting of the inclined surface 214 of the push portion 213 facilitates the push portion 213 to extend into the bottom of the chip contact 220 on the one hand (as shown in FIG. The inclined surface 214 of the elastic piece 221 cooperates with the inclined surface of the free end 222 of the elastic piece 221 to reduce the sliding stroke of the pusher 210 .

As shown in FIGS. 2-7 , in some embodiments of the present application, the chip contact retractable mechanism 200 is arranged on the side of the first side wall 120 facing away from the process box installation cavity 110, and the first side wall 120 is provided with Mounting hole 123 and limiting hole 122, chip contact 220 and chip contact mounting frame are arranged at mounting hole 123 places, and the part of pushing member 210 stretches in the process box installation chamber 110 from limiting hole 122 places, and limiting hole 122 It is a long hole, and its length direction is the same as the moving direction of the pusher 210. The part of the pusher 210 placed in the limit hole 122 can move back and forth in the limit hole 122 along the direction in which the pusher 210 pushes the chip contact 220, That is, the limiting hole 122 restricts the forward and backward movement of the pusher 210 along its length direction, and plays a role of guiding and giving way to the movement of the pusher 210 . The trigger mechanism and the part of the pusher 210 extending into the process box installation cavity 110 cooperate to drive the movement of the pusher 210, that is to say, the trigger mechanism is arranged on the process box 300, and the process box 300 is installed in the process box installation cavity 110. The member 210 protrudes into the process cartridge installation cavity 110 so as to be able to cooperate with the trigger mechanism.

In some preferred embodiments of the present application, the chip 310 is arranged on the end cover of one end of the process box 300 along its length direction, and the first side wall 120 is the two sides of the process box installation cavity 110 in the process box 300 length direction One of the walls, in this embodiment, the first side wall 120 is on the right side plate (with the front of the image forming device as the front side) of the process box installation chamber 110, because the chip 310 on the process box 300 is generally arranged on The right side of the process box 300 (with the direction in which the process box 300 is installed on the image forming apparatus body 100 as a reference) at the end cover, so the chip contact retractable mechanism 200 is arranged on the right side plate of the process box installation cavity 110 to reduce the The modification of the original structure of the image forming apparatus body 100 and the process box 300 is more convenient for processing and production. It is enough to set the mounting position of the chip contact retractable mechanism 200 in the inner area of the image forming apparatus body 100 on the side, and for the process cartridge 300 used in conjunction with the image forming apparatus in the second embodiment below, it only needs to be located on the right side of the process cartridge 300. The trigger mechanism of the chip contact retractable mechanism 200 can be provided at the side end cover, without changing the installation position of the chip 310 or the structure of the process box 300, and the improvement method is simple.

It should be noted that, in the following statements in this embodiment, the front of the main body 100 of the image forming apparatus is taken as the reference direction for illustration.

Of course, in some possible embodiments, the chip contact retractable mechanism 200 can also be arranged on other side wall panels of the process box installation cavity 110 body. At this time, the structure of the process box 300 needs to be modified accordingly. That is to say, the chip 310 on the process box 300 is changed to the corresponding side end corresponding to the position where the chip contact telescopic mechanism 200 is provided, and a trigger mechanism is set at the side end corresponding to the chip 310. For example, the chip contact telescopic mechanism 200 is arranged on On the left side plate of the process box installation cavity 110, correspondingly, the chip 310 on the process box 300 is changed to the left end cover of the process box 300, and the trigger mechanism is also arranged on the left end cover of the process box 300.

In the embodiment of the present application, the first side wall 120 is provided with a process box slideway 121, and the first side wall 120 is provided with a first slideway plate 130 on the side facing away from the process box installation cavity 110. In an example, as shown in FIG. 5 and FIG. 6 , a process cartridge slideway 121 is provided on the right side plate, and a first slideway plate 130 is provided on the side of the right side plate facing away from the process cartridge installation cavity 110 . The first slideway plate 130 is provided with a process cartridge chute 131, an installation gap 132 for placing the chip contact mounting frame and the chip contact 220 and a guide block 133 for installing the pusher 210, the first slideway plate 130 It is the original structure of the image forming apparatus body 100, and the process cartridge chute 131 provided on it is a chute with an upper side opening, the opening is inclined upward and faces the front upper part of the image forming apparatus, and the right end of the process cartridge 300 slides from the process cartridge. The slot 131 is inserted into the body of the process box installation chamber 110 , and the process box chute 131 plays a guiding role for the installation of the process box 300 . The chip contact 220 and the chip contact mounting frame are installed at the installation gap 132 of the first slideway plate 130. This application uses the original structure of the image forming device body 100 to set the installation position of the chip contact retractable mechanism 200, which can reduce the number of chips. The setting of the installation parts of the contact telescopic mechanism 200 further reduces the overall volume of the chip contact telescopic mechanism 200, thereby saving the installation space of the chip contact telescopic mechanism 200. On the other hand, the first side wall 120 at the installation gap 132 can The fixed end of the chip contact 220 is blocked to ensure that the free end 222 of the chip contact 220 maintains a stable position when the pusher 210 pushes the chip contact 220 .

The installation notch 132 is located at the bottom of the process cartridge chute 131 and is close to one end of the front side of the image forming apparatus body 100. This setting realizes that the chip contact retractable mechanism 200 is located at the front side of the image forming apparatus body 100 as a whole, so that the process cartridge 300 is inserted into the image forming apparatus body 100. When the process box installation chamber 110 is in the body, the trigger mechanism on the process box 300 can trigger the chip contact telescopic mechanism 200 before the process box 300 is put in place, so that the pusher 210 moves, and the pusher 210 can also move along with the process box 300. Insert and push the core contacts continuously until the chip contacts 220 are pushed out and fully contact with the chip 310 on the process cartridge 300 .

The guide block 133 is located at the installation notch 132 and at one end of the installation notch 132 close to the front side of the image forming device body 100 , the guide block 133 is provided with a guide chute 134 , and the sliding part 211 of the pusher 210 is placed in the guide chute 134 And can slide in the guide chute 134, the guide chute 134 plays a guiding role to the pusher 210, so that the pusher 210 can slide along the direction of the guide chute 134, ensuring the accuracy of the positional movement of the pusher 210, so that It can only move back and forth in a straight line along the direction of the guide chute 134 , which avoids the situation that the chip contacts 220 cannot be successfully pushed out or pushed out in place due to the deflection of the pushing member 210 . Further, the upper opening of the guide chute 134 faces to the left side of the image forming apparatus body 100, that is to say, when the first slideway plate 130 is installed in the image forming apparatus body 100, the upper opening end of the guide chute 134 faces to the right side. Plate, the right plate blocks the upper opening of the guide chute 134, so that the pusher 210 can only move back and forth in a straight line along the direction of the guide chute 134, without moving up and down left and right.

In some embodiments of the present application, as shown in Fig. 3, Fig. 4, Fig. 6, Fig. 7, Fig. 13 and Fig. 14, the end of the pushing member 210 extending into the process cartridge installation cavity 110 is bent upwards, that is, forcing The push part 212 is an L-shaped structure, that is, it includes a horizontal side and a vertical side. One end of the horizontal side of the pushing part 212 is connected to the sliding part 211, and the other end passes through the limiting hole 122, and the horizontal side crosses the limiting hole 122, and Its two ends are divided into the both sides that are positioned at limit hole 122, and the free end 222 of pushing part 212 vertical sides is towards the top of process box installation cavity 110 body, because when process box 300 is installed in process box installation cavity 110, process box 300 slide track along the process box slideway 121 and process box chute 131 is predetermined, that is, at first the inclination of a larger inclination angle slides downwards, and then slides down with a gentle inclination, that is to say, the sliding track of the process box 300 does not slide horizontally track, and the pushing direction of the pushing member 210 is to push back horizontally, thus, the process box 300 cannot give a horizontal thrust to the pushing part 213, and when the process box 300 slides obliquely downward, along with the movement of the process box 300, the process box The trigger mechanism of 300 can give an oblique downward force to the pushing part 212. Therefore, there is a clearance gap between the trigger mechanism on the process cartridge 300 used in conjunction with the image forming apparatus in the second embodiment and the process cartridge 300. That is, the hook gap 321 in FIGS. 14-22 .

The working state of the process box 300 and the chip contact retractable mechanism 200 is shown in Figures 15-22, and Figure 15 is a schematic structural view of the first state of the process box 300 and the chip contact retractable mechanism 200; Figure 16 is a schematic view of Figure 15 Partial enlarged view at C; FIG. 17 is a schematic structural view of the second state in which the process box 300 cooperates with the chip contact retractable mechanism 200; FIG. 18 is a partial enlarged view at D in FIG. 17; FIG. 19 is the process box 300 and The structural diagram of the third state of the cooperation of the chip contact telescopic mechanism 200; FIG. 20 is a partial enlarged view of E in FIG. 19; FIG. 21 is the structural diagram of the third state of the process box 300 and the chip contact telescopic mechanism 200; FIG. 22 is a partial enlarged view at F in FIG. 21 . When the process box 300 is slidably installed in the process box installation cavity 110 along the process box slideway 121 and the process box slideway 131, the initial state of the trigger mechanism and the pushing part 212 is not in contact (as shown in Figures 15 and 16). , as the process box 300 slides down, the upwardly bent end of the forcing portion 212 stretches into the hook gap 321, and the trigger mechanism contacts the side of the upwardly bending end of the forcing portion 212 (as shown in Figures 17 and 18 As the process box 300 slides down, the upwardly bent end of the pushing portion 212 continues to extend upwards into the hook gap 321, and when the trigger mechanism slides down, it pushes the upwardly bent portion of the pushing portion 212 so that the pushing member 210 touches the chip. Move in the direction of point 220, and the trigger mechanism moves downward along the upward bending part of the pushing part 212 (as shown in Figure 19 and Figure 20); Through the gap 321 of the hook, the trigger mechanism continues to slide down. When the trigger mechanism slides down, it pushes the pushing part 212 to bend upward so that the pusher 210 continues to move toward the chip contact 220, and the trigger mechanism continues to move upward along the pushing part 212. The bending part moves downward, and when the process box 300 is installed in place, the trigger mechanism promotes the pusher 210 to move in place, that is, the chip contact 220 is fully pushed out and contacts with the chip 310 (as shown in FIGS. 21 and 22 ), the chip contact The state of fully extending and mating with the chip 310 is shown in FIG. 23 . Since the upwardly bent part of the forcing part 212 passes through the hook gap 321 and is located in the hook gap 321, when the process cartridge 300 is drawn out, the trigger mechanism will drive the forcing part 212 to retreat simultaneously to realize the reset of the pushing part 210. That is to say, the hook gap 321 between the trigger mechanism and the process box 300 can allow the forcing part 212 to pass through, thus, the trigger mechanism will only give a backward thrust to the forcing part 212 to realize the movement of the pushing part 213 , when the process box 300 is installed in place, the upwardly bent part of the forcing part 212 passes through the hook gap 321 and is placed in the hook gap 321. When the process box 300 is drawn out of the process box installation cavity 110, the trigger mechanism can give the forcing part 212 A forward pulling force realizes that the trigger mechanism pulls the pusher 210 forward away from the lower end of the free end 222 of the chip contact 220 (the lower end here refers to the position shown in FIG. 7 ), and the chip contact 220 is under the action of its own elastic force. Realize reset, that is, retract in the mounting hole 123. The setting of the pushing part 212 as an L-shaped structure can cooperate with the trigger mechanism of the process box 300 to realize the reciprocating movement of the pushing part 213, and the driving method is simple and ingenious.

Certainly, the pushing part 212 can be other structures, such as a rod-shaped structure, and the pushing part 212 protrudes from the limit hole 122 perpendicular to the right side plate. The mechanism is that a slideway is set on the right end cover of the process box 300 to fit the sliding track of the process box 300, so that the slideway only has a backward thrust or a forward pull force on the pushing part 212 .

In some embodiments of the present application, there are multiple chip contacts 220, and the installation indicating block 236, the contact spring 251, the limit installation hole 234 and the card protrusion 244 are all set to be multiple corresponding to the multiple chip contacts 220, and the multiple The chip contacts 220 are arranged parallel to each other on the chip contact mounting frame, the free ends 222 of the plurality of chip contacts 220 are located on the same side, the sliding part 211 is connected with the pushing part 213 to form a T-shaped structure, and the pushing part 213 can move. Simultaneously push the free ends 222 of the plurality of chip contacts 220 . The number of chip contacts 220 of the present application is determined according to the chip 310 on the process box 300. A chip contact 220 can be set on the chip contact telescopic mechanism 200, or 2, 3, 4 or more can be set. .
