The conventional rotary cutter is shown in Fig. 2 and
As shown in FIG. 3, both ends of the rotary blade 2 are rotatably supported by a shaft 3 on both side plates (not shown). Moreover, the cutting edge of the rotary blade 2 is inclined on the circumferential surface of the rotating cylinder. On the other hand, fixed blade 1
is rotatably supported on both side plates (not shown) by support shafts 4 at both ends thereof, and the cutting edge of the fixed blade 1 is supported by a spring 7 via a pin 5 provided on the fixed blade 1. is pressed against the cutting edge of the rotary blade 2. or,
As another configuration of the fixed blade 1, as shown in FIG. 4, the fixed blade 1 composed of only a blade metal is supported on a base plate 8 by a leaf spring 9, and the cutting edge of the fixed blade 1 is It is pressed against the cutting edge of the rotary blade 2 by a leaf spring 9. When the rotary blade 2 is rotated by a drive device (not shown), the roll paper 6 placed between the fixed blade 1 and the rotary blade 2 is cut. In such a configuration, the fixed blade 1 is attached to the roll paper 6.
In the process of cutting, cutting resistance causes deflection in the length direction, and depending on the amount of deflection, it may cause cutting failures, so the fixed blade 1 needs to have enough rigidity to withstand the cutting resistance. Cutting a roll of heat-sensitive recording paper with a thickness of 65 μm and a width of 300 mm requires a rigidity equivalent to or higher than that of a hardened blade metal with a thickness of 3 mm and a width of 12 mm. Therefore, in the fixed blade 1 that has a structure in which the blade 1b with a small cross section is inserted as shown in Figs. 2 and 3, the blade holder 1a needs to be made of mild steel with a large cross section in order to maintain its rigidity. This increases the weight of the entire rotary cutter device, which is undesirable.

ばあり、好ましくなかつた。 On the other hand, the conventional rotary cutter guides the roll paper 6 to the cutting position as shown in FIG.
A paper insertion guide plate 10 is attached to the fixed blade 1 on the side facing the surface including the cutting edge of the fixed blade 1, so that the roll paper 6 can be inserted smoothly. However, with such a conventional structure, an error occurs in the installation work of the fixed blade 1 and the paper insertion guide plate 10, which may change the cutting performance or cause the fixed blade to 1 and the paper insertion guide plate 10, the leading end of the roll paper 6 often gets caught and prevents the roll paper 6 from entering smoothly, which is undesirable.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. In FIG. 1, a paper insertion guide portion 1c is integrally provided on the blade holding base 1a of the fixed blade 1 in a direction perpendicular to the plane including the cutting edge so that its cross section is approximately L-shaped. . Paper insertion guide part 1c
The blade holder 1 acts as a rib in the direction in which the fixed blade 1 receives cutting resistance in the length direction.
A can be made thin as a whole and may be made of aluminum or synthetic resin.

が嵌り込むような溝としてもよい。 Further, the blade holding stand 1a is provided with a stepped portion 1d for receiving the lower end of the blade 1b, and the blade 1b is held with adhesive or fixing means such as screws with the stepped portion 1d as a reference. Since it is attached to the base 1a, by maintaining the accuracy of the position of the stepped part 1d and the height of the blade 1b, the installation height of the blade 1b is kept slightly lower than the paper insertion guide part 1c. There is. Also, the step part 1d is attached to the blade 1b as shown in Fig. 1-B.
It is also possible to form a groove into which the material fits.
一方、刃金保持台１ａは、切断抵抗を受ける方
