[0029] Figure 5 It is a perspective view of the chip support, the first limiting member and the second limiting member of the processing cartridge involved in the utility model.
[0030] As shown in Figure 1 and Figure 5 , the shell is provided with a chip support 60 for mounting the chip 50, the chip support 60 comprises at least one fixing part 61 for preventing the chip 50 from falling off from the chip support 60, and after the chip 50 is mounted to the chip support 60, the direction of the processing cartridge 100 is also applicable to the direction of the chip 50.
[0031] Figure 6 It is a perspective view of the first chip mounted to the chip support of the processing cartridge involved in the utility model. Figure 7 It is a perspective view of the second chip mounted to the chip support of the processing cartridge involved in the utility model.
[0032] In the actual production process, due to the production process and other problems, the existing first chip 54 and second chip 55, as shown in Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , compared with the second chip 55, the size of the first chip 54 in the left-right direction is smaller than that of the second chip 55 in the left-right direction, or in other words, the distance between the first chip 54 and the non-driving end in the left-right direction is greater than that between the second chip 55 and the non-driving end.
[0033] Compared with the first chip 54, the distance between the storage member 52 and the non-driving end of the second chip 55 is smaller than that between the storage member 52 and the non-driving end of the first chip 54; along the thickness direction of the substrate 51, the electrical contact 53 of the first chip 54 overlaps at least part of the storage member 52, and the electrical contact 53 of the second chip 55 does not overlap the storage member 52.
[0034] The following describes that the chip 50 is installed on the left end cover 30, and the installation direction of the chip 50 is from the driving end to the non-driving end during the assembly process of the processing box 100. The reason is that the shell / main body interferes with the installation path of the chip 50 during the installation process of installing the chip 50 from the non-driving end to the driving end, so that the chip 50 cannot be installed on the chip support 60 / shell.
[0035] According to the installation direction of the chip 50 described above, as shown in the figure, Figure 5 The processing box 100 provided by the utility model further comprises a first limiting piece 70 and a second limiting piece 80 arranged on the shell. In the left-right direction, the first limiting piece 70 is located between the chip support 60 and the second limiting piece 80. The connection area of one of the shell and the chip support 60 connected with the first limiting piece 70 is smaller than the connection area of one of the shell and the chip support 60 connected with the second limiting piece 80. In addition, in the left-right direction, the first limiting piece 70 and the second limiting piece 80 are closer to the non-driving end than the chip support 60. In the left-right direction, the second limiting piece 80 is closer to the non-driving end than the first limiting piece 70.
[0036] As shown in the figure, Figure 6 When the first chip 54 is installed on the chip support 60, the first limiting piece 70 is used to prevent the first chip 54 from falling off the installation support 60. Meanwhile, the first limiting piece 70 can also position the first chip 54.
[0037] As shown in the figure, Figure 7 When the second chip 55 needs to be installed on the chip support 60, the first limiting piece 70 can be removed from the shell to avoid interfering with the installation of the second chip 55. The second limiting piece 80 is also used to prevent the second chip 55 from falling off the installation support 60. Meanwhile, the second limiting piece 80 can also position the second chip 55.
[0038] In some embodiments, the first limiting piece 70 can also be movably arranged relative to the shell, for example, the first limiting piece 70 can be telescopic relative to the shell, or the first limiting piece 70 can be deflected relative to the shell / chip support 60. In this way, the first limiting piece 70 does not need to be removed from the shell before the installation of the second chip 55, and the installation of the second chip 55 is not affected.
[0039] In some embodiments, in the left-right direction, the first limiting piece 70 and the chip support 60 are connected with each other, but not connected with the shell. Such an arrangement can not only enhance the limiting effect of the first limiting piece 70 on the first chip 54, but also provide a fulcrum for removing the first limiting piece 70, so that the removal process becomes easy.
[0040] In some embodiments, the first limiting member 70 is arranged in an "L" shape, so that the first limiting member 70 is easy to grasp during the process of removing the first limiting member 70, thereby making the removal process easy, and in addition, such an arrangement can also reduce the connection area of the first limiting member 70 connected to one of the housing and the chip support 60, thereby reducing the force requirement for removing the first limiting member 70.
[0041] In some embodiments, the first limiting member 70 is made of a material with weak flexibility, so that the difficulty of removing the first limiting member 70 can also be reduced.
[0042] In some embodiments, the second limiting member 80 is also provided with a reinforcing portion 81 for further preventing the second chip 55 from falling off, and the reinforcing portion 81 is arranged on the side wall of the second limiting member 80 facing the non-driving end.
[0043] It should be noted that after the chip 50 is mounted to the chip support 60, the chip 50 can be pressed against the chip support 60 in a direction intersecting the mounting direction, so that after the chip 50 is mounted to the chip support 60, the processing cartridge 10 does not need to install a protective member on the end of the chip 50 away from the non-driving end, and the protective member is used to prevent the chip 50 from falling off in a direction opposite to the mounting direction of the chip 50.
[0044] The inventive concept of the present application is also applicable to the case where the chip support 60 is arranged on the right end cover 40, and the chip 50 is also mounted to the right end cover 40, at this time, the mounting direction of the chip 50 is from the non-driving end to the driving end.

[0047] Firstly, the housing of the processing cartridge 100 is provided with a first limiting member 70 and a second limiting member 80, the first limiting member 70 is used to prevent the first chip 54 from falling off the mounting support 60, and the second limiting member 80 is used to prevent the second chip 55 from falling off the mounting support 60, so that the first chip 54 and the second chip 55 can be mounted into the processing cartridge 100, and such an arrangement improves the versatility of the processing cartridge 100 and reduces the production cost of the processing cartridge 100.
[0048] Secondly, the connection area of one of the housing and the chip support 60 connected to the first limiting member 70 is smaller than the connection area of one of the housing and the chip support 60 connected to the second limiting member 80, so that the force requirement for removing the first limiting member 70 can be reduced, and the removal process of the first limiting member 70 becomes easy.
[0049] In the third aspect, the first limiting member 70 is provided in an "L" shape, so that the first limiting member 70 becomes easy to grip during the process of removing the first limiting member 70, and at the same time, the connecting area of the first limiting member 70 connected to one of the housing and the chip support 60 can be reduced, so that the process of removing becomes easy.
