[0070] Such as figure 1 As shown, the image forming system 1 of this embodiment includes: an image forming device 1a; a post-processing device (not marked) located downstream of the paper outlet E of the image forming device 1a, and the paper discharged from the paper outlet E of the image forming device 1a is directly into the post-processing unit. The post-processing device includes: a paper conveying device 20, a paper cutting device 10 and a tape application device (not shown), along the paper feeding direction B, the paper cutting device 10 is located downstream of the paper conveyance device 20, and the tape application device is located at Downstream of the cutting device 10.
[0071] The paper conveying device 20 is not only used to convey the image-formed paper discharged from the paper outlet E of the image forming device 1a to the paper cutting device 10, but also used to correct the paper so that the image-formed paper can be adjusted correctly. The paper cutting...

[0145] The difference between the second embodiment and the first embodiment is that in the second embodiment, as Figure 8 As shown, the platen part 130 is a platen roller, which is connected to the rotating shaft 140 and can roll along the paper cutting direction A on the platen bearing surface S; Figure 9 As shown, the cutting knife 120 is annular, and the tail of the cutting knife 120 is fixed on the circumferential surface of the platen roller 130. In the paper cutting state, the lowest point (ie, the tip) of the cutting knife 120 is located in the cutting groove 111; The traction part 150 moves along the paper cutting direction A, and the traction part 150 is connected with the rotating shaft 140 .
[0146] In this embodiment, the pulling part 150 is driven to move in two opposite directions, so that the paper can be cut in two opposite directions.
[0147] In the paper cutting device of this embodiment, in the non-cutting state, the platen roller is placed on the bear...

[0150] The difference between the third embodiment and the first embodiment is that in the third embodiment, if Figure 10 to Figure 12 As shown, the platen part 130 includes a first platen 131 and a second platen 132, and the first platen 131 and the second platen 132 can move along the direction F away from the platen bearing surface S, The first paper pressing strip 131 and the second paper pressing strip 132 can be pressed on both sides of the cutting groove 111; in the paper cutting state, the tail of the cutting knife 120 and the bottom of the cutting groove 111 and the cutting groove 111 are along the cutting direction A Both extended side walls are in contact, and the highest point (ie, the tip) of the cutting knife 120 is located above the cutting groove 111 .
[0151] In this embodiment, the two ends of the first paper pressing bar 131 and the second paper pressing bar 132 are fixed together so that the movement of the first paper pressing bar 131 and the second pape...
