When a user puts valuables in a locker and inputs a personal identification number by using a plurality of key buttons 9 of the input setting unit 6, the door of the locker 1 is locked and a receipt is issued from the printer 5. The user presses this receipt against the cutter provided in the paper piece supply window 8 to cut and carry it. However, when cutting a receipt, there are people who cut the receipt in the middle of issuing the receipt and people who violently cut it without using the cutter, so the tip of the next issue of the receipt will be the cutting edge of the cutter. There was a problem of biting and clogging.

Therefore, in order to solve such a problem, it is necessary to attach to the conventional printer 5 an automatic cutter mechanism that automatically cuts a receipt in place of the conventional hand cutting cutter. As shown in FIG. 9, a commercially available auto-cutter mechanism supports a rotary blade 19 rotatably on a frame 18, attaches a fixed blade (not shown), and fixes a motor (or rotary solenoid) 20 to the frame 18. Attach the shaft of to the rotary blade 19.

A paper tape, which is a receipt paper, is guided between the rotary blade 14 and the fixed blade, and a print head (not shown) prints the unique number of the rocker used and the usage time on the paper tape, and then the motor (or rotary solenoid). ) 20, the rotary blade 19 is rotated to cut the printed portion of the paper tape, and the paper is supplied from the paper piece supply window 8.

As shown in FIG. 9, in this auto cutter mechanism, the rotary blade 19 is directly rotated by the motor 20, so that the frame 18 is provided with the electric wire 21 for supplying the electric current to the motor 20. In addition, the frame 18 is fixed to the bottom of the case of the printer 5 with a screw 18a so that the mounting position of the frame 18 is not displaced by the rotation of the motor 20.
