Abstract:

A sheet perforation device, shown in Fig. 4, comprising a motor (22) for driving a reciprocating punch blade (21), a punching unit (20') for making two or more holes in one end of a sheet (3), and a CPU (55) for controlling it. The CPU (55) detects whether or not the punch blade (21) has been driven into a home position where the stop position of the punch blade (21) is permitted, performs reverse rotation brake control on the motor (22) for a predetermined time after a moment in time when the punch blade (21) is driven into the home position, and extends reverse rotation brake control on the motor (22) after the punch blade (21) arrived at a predetermined position. When the punch blade stops, it can be stopped in the home position.
