[0050] The front shell 13 is detachably connected with the front side of the base 11, and the paper outlet 18 is arranged on the front shell 13;

[0051] The left shell 14 is detachably connected with the left side of the base 11;

[0052] The right shell 15 is detachably connected with the right side of the base 11;

[0053] The rear shell 12 is detachably connected with the left shell 14 and the right shell 15 and is rotatably arranged relative to the base 11.

[0054] The side of the rear shell 12 away from the base 11 is fixedly connected with the top shell 16 through the first magnetic attraction member 31, and the rear shell 12 and the top shell 16 enclose the paper inlet 17.

[0055] When the shell assembly structure is assembled, the base 11, the front shell 13, the left shell 14, the right shell 15, and the top shell 16 are first installed, and then the rear shell 12 is connected with the left shell 14 and the right shell 15 by the hinge 2. At this time, the rear shell 12 is rotated relative to the base 11, the first magnetic attraction member 31 is fixed at the top shell 16 or the rear shell 12, and the rear shell 12 is rotated. Under the action of the first magnetic attraction member 31, the position relationship of the rear shell 12 relative to the top shell 16 and the base 11 is fixed. It can be seen that, compared with the prior art, each shell module needs to be fixed and assembled by workers. In the present application, the rear shell 12 is fixed by magnetic attraction, which is convenient and fast. When the printer needs to be repaired, the working state of the internal functional components of the printer can be checked by turning over the shell without the need for additional tools such as screwdrivers, and the entire rear shell 12 does not need to be removed from the shell structure, further improving the convenience of the structure during maintenance.

[0056] It can be understood that the rear shell 12 and / or the top shell 16 are made of metal material.

[0057] In one embodiment, the hinge 2 includes a first hinge 21 and a second hinge 22.

[0066] In an embodiment, a through slot 161 is formed in the top shell 16, and a second magnetic attraction member 32 is fixed to the top of the left shell 14 and the right shell 15. The top shell 16 is detachably connected with the left shell 14 and the right shell 15 through the second magnetic attraction member 32.

[0067] When installing the top shell 16, the top shell 16 is fixed on the top of the left shell 14 and the right shell 15 by the magnetic force of the second magnetic attraction member 32, which is convenient and fast. When maintaining the printer, the user can put his hand into the through slot 161 to take out the top shell 16 for the convenience of observing the internal functional components of the printer. In terms of assembly, the convenience of assembling the structure is further improved. In the aspect of later maintenance, the top shell 16 is easy to disassemble without the need of additional tools, which is convenient and fast.

[0068] It can be understood that the top shell 16 is made of metal material.

[0084] When the printer works, the paper first flows into the scanner 5 from the paper inlet 17, and the paper output from the scanner 5 may be curled, especially the larger paper such as A3 size paper, at this time, the first limiting press plate 7 is arranged on one side close to the outlet of the scanner 5, which can limit the paper output from the scanner, avoid the curled paper to be printed to enter the printing head 6 for smooth printing, and the second limiting press plate 8 also has the same effect as the first limiting press plate 7, but the second limiting press plate 8 further limits the curled paper.

[0085] Specifically, the printing head 6 includes an upper printing head arranged above the printing channel 4 and a lower printing head, the upper printing head is used for the front side of the paper, and the lower printing head is used for the back side of the paper.

[0086] Specifically, it further includes a transmission roller 9 embedded in the second limiting press plate 8 for guiding the paper movement between the printing channel 4 and the second limiting press plate 8. The transmission roller 9 provides power to the paper to drive the paper to enter the printing head 6 part smoothly and complete the printing smoothly.

[0087] Specifically, the right shell 15 is provided with a hatch 153. When the printer is jammed or needs to be repaired, not only the outer shell can be disassembled from the rear shell 12 and the top shell 16 for maintenance, but also the hatch 153 can be opened for maintenance.
