(Cutter unit operation)
The operation of the cutter unit 60 will be described with reference to FIG. The paper 100 is transported along a paper transport path formed by the pair of paper transport guides 41 and 42, and the end side 100a of the transported paper 100 contacts the pair of cutters 62 (FIG. 12A). . When the paper 100 is further conveyed, a notch 101 is formed on the edge side 100a of the paper 100 while the edge side 100a of the paper 100 is pushed toward the lower paper conveyance guide 42 by the pair of cutters 62 (FIG. 12 (b)). When the paper sheet 100 with the cuts is further conveyed, the edge side 100a of the paper 100 other than the position of the cuts 101 abuts the bracket 61, and the edge side 100a is moved to the lower paper conveyance guide 42 side by the bracket 61. The bracket 61 is pushed up against the biasing force of the spring 65 by the reaction force, the pair of cutters 62 are separated from the paper 100 (FIG. 12C), and the paper 100 passes through the paper conveyance path ( FIG. 12 (d)).

  A part of the pair of cutters 62 protrudes from the bracket 61, the end side 100 a of the paper 100 comes into contact with the cutter 62, and then the end side 100 a other than the notch 101 position of the paper 100 is bracketed by the end side 100 a. Since 61 is pushed up against the urging force of the spring 65, the cut length L2 of the paper 100 can be set by the protruding length L1 of the pair of cutters 62, and the type, size, and thickness of the paper 100 can be set. The binding strength can be adjusted according to the situation. In this embodiment, the pair of cutters 62 have a disk shape, but the present invention is not limited to this, and the cutter 62 may have a saw blade on the outer periphery or a star shape. Although such variously shaped cutters can be used, the cutting of the paper 100 is performed until the bracket 61 is pushed up against the urging force of the spring 65 by the end side 100a other than the position of the cutting 101 of the paper 100. Therefore, the cut length L <b> 2 of the paper 100 is set by the length that a part of the cutter protrudes from the bracket 61.

(Move the cutter)
The movement of the pair of cutters will be described with reference to FIGS. FIG. 13 is a diagram illustrating the movement of the cutter, and FIG. 14 is a diagram illustrating a change in the paper cutting position.

  In this embodiment, the cutter unit 60 is disposed in the moving unit 40, and when the moving motor 48 is driven, the moving link 47 rotates and the pin 47a moves through the long hole 46a, so that the operation plate 46 is fixed. The sheet conveyance guide 41 and the sheet conveyance guide 42 that have been moved reciprocate together in the width direction of the sheet conveyance path, and the cutter unit 60 moves together therewith.

  As for the timing of the notch 101 of the sheet 100, the movement link 47 is rotated by the driving of the movement motor 48, and the edge side of the sheet 100 contacts the cutter 62 at the position where the pin 47 a is closest to the side plate 22. Is formed (FIG. 13A). Further, the paper 100 with the cuts is conveyed, the bracket 61 is pushed up against the urging force of the spring 65 by the edge side other than the position of the cuts 101 of the paper 100, and the pair of cutters 62 are moved up. The paper 100 passes through the paper transport path.

  Before the next sheet 100 is carried into the sheet conveyance path, the movement motor 48 is driven to rotate the movement link 47, and the pin 47 a moves to a position farthest from the side plate 22. At the moved position, the edge side 100a of the next sheet 100 comes into contact with the cutter 62, and a notch 101 of the sheet 100 is formed (FIG. 13B). Further, the next paper 100 with the cut formed therein is conveyed, the bracket 61 is pushed up against the urging force of the spring 65 by the edge side 100 a other than the position of the cut 101 of the paper 100, and the pair of cutters 62 are removed from the paper 100. The paper 100 is separated and passes through the paper conveyance path. In this manner, the notch 101 of the paper 100 is formed by repeating the position where the pin 47a is closest to the side plate 22 and the position where the pin 47a is farthest from the side plate 22 (FIG. 14).

  In this embodiment, the notch 101 is formed in the paper 100 by repeating the position where the pin 47a is closest to the side plate 22 and the position where the pin 47a is farthest from the side plate 22, but at this intermediate position. The notch 101 may be formed on the paper 100, and the notch position can be set by the rotation angle of the pin 47a.

  In this way, by forming the notch 101 on the edge side to be stuck at the time of bookbinding processing of the paper 100, it is possible to achieve the binding strength by the notch 101, and no dust is generated, and the dust is not generated. There is no need to disperse the device due to scattering and to provide a waste collection unit.

  Further, the edge side of the conveyed paper 101 contacts the cutter 62 to form the notch 101, and the bracket 61 is pushed against the biasing force of the spring 65 of the biasing means by transporting the paper 100 on which the notch 101 is formed. The cutter 62 is moved away from the paper 100, and the notch 101 is automatically formed by the conveyance of the paper 100, so that the structure is simple using the conveyance of the paper 100.
