Conventionally, in a vertical cutter device, the vertical size and horizontal size, which are the cutting dimensions, are determined by screwing a turnbuckle screw between a pair of cutters and operating the turnbuckle screw to move the distance between the two cutters. The vertical size was determined by measuring with a ruler.

Further, in the position specifying device and the alignment device, the position of each specifying member is set by operating a knob or the like and measuring with a scale or the like.

In addition, in the feeding device, the transfer distance is set by adjusting the movement angle of a lever that is interlocked with the extrusion member for cutting and cutting.

This transport distance determined the relative position of the book cutter and the edge cutter, and determined the horizontal size of the book (see Japanese Utility Model Publication No. 58-26799 for an example of such a three-way cutter). ).

<Problems to be Solved by the Invention> However, the conventional three-way cutter has a problem in that it takes time and effort to set the positions of the top and bottom cutters, the position regulating device, and the size of the alignment device.

In addition, in feeding devices, it is difficult to accurately determine the relationship between the lever movement angle and the transfer distance, so it is necessary to set the lever movement angle and confirm the transfer distance several times to ensure accurate transfer.
