く。FIG. 14 is a perspective view of a conventional paper cutter mechanism described in Japanese Patent Application No. 4-186397. The wire 10 hooked on the hook portion 15 of the round blade base 26 via the pulleys 8 provided on the back side and the front side in the longitudinal direction of the cutter frame 1 causes the motor 9 having the pinion 12 on the rotating shaft to rotate the wire 10. At the same time, the pulley 8 rotates (the pulley 8 and the gear 13 on the motor 9 side are integrally configured) to move in the rotation direction of the pulley 8, so that the round blade base 26 is pulled by the wire 10 to rotate the motor 9 forward. The cutter frame 1 reciprocates from the back side to the front side in the longitudinal direction, and from the front side to the back side when the motor 9 reverses. 32
Is a sliding part of the round blade base 26. The tension coil spring 7 provided on the hook portion 15 of the round blade base 26 is the wire 1
The tension is generated at 0 to prevent the pulley 8 and the wire 10 from slipping. One end of the cutter frame 1 bent in a key shape is the running guide portion 4 of the round blade base 26. By making a part of the round blade base 26 concave and fitting it into the traveling guide portion, the circular blade base 26 reciprocates while sliding on the traveling guide portion 4. The fixed blade 2 is fixed to the cutter frame 1 by means such as welding. When the roll paper placed between the fixed blade 2 and the round blade 5 is separated from the fixed blade 2,
The front Russell portion 33 guides the roll paper or the like to the vicinity of the fixed blade 2.

The round blade 5 and the rotation roller 16 are integrated with the support bearing 17 by means such as press fitting or adhesion (hereinafter referred to as a round blade unit). The rotation roller 16 is in contact with the fixed blade 2.
The round blade unit and the round blade pressing spring 19 are inserted in the round blade rotating shaft 11 of the round blade base 26. At this time, the round blade 5 is pressed against the fixed blade 2. As described above, when the round blade base 26 slides and reciprocates on the cutter frame 1, the rotation roller 16 in contact with the fixed blade 2 rotates to rotate the round blade unit and rotate the fixed blade 2 and the round blade. The roll paper placed between 5 is cut.

を奏する。As described above, in the cutter mechanism of the present invention, the mechanism for pressing the rotating roller against the fixed blade by the spring (or the elastic force of the material of the rotating roller) and the movable table and the rotating roller sandwich the fixed blade. It is arranged so that it is pushed in and presses the rotating roller against the fixed blade (or the elastic force of the material of the rotating roller).
With the reaction force of the pressing force, the fixed blade is sandwiched between the rotating roller and the moving table, and the moving table and the blade edge of the round blade are arranged so as to sandwich the running guide part and the fixed blade. With the pressing force that presses the blade against the fixed blade and the reaction force of the pressing force, the traveling guide part and the fixed blade are sandwiched by the moving table and the round blade, and the cutting that the round blade receives when cutting roll paper etc. This has the effect of suppressing the load and preventing the inability to cut or defective cutting caused by the influence of the cutting load.

Even if it is pressed against the fixed blade, there is no problem that the rotation roller is deformed with time at the standby position and cannot rotate.
