There are some combinations of In the shearing device, the fixed blade 1 is generally made of the same blade material as a whole, but the movable blade 2 has a blade tip 3 and a movable blade main body 4 made of different materials, and the blade tip 3 is made of different materials. I'm reducing the amount. However, with this type of conventional equipment,
Since the blade tip 3 is inserted into the engagement groove 5 of the movable blade body 4 at intervals and fixed with adhesive, it is necessary to control the dimension of the gap between the movable blade body 4 and the blade tip 3 and the amount of adhesive. There were some drawbacks.

である。DISCLOSURE OF THE INVENTION In view of the above, this invention provides a movable blade in which a cutting edge portion formed of a material different from the movable blade body is attached to an engagement groove provided in the movable blade body; A shearing device comprising: a fixed blade that cooperates to shear paper; the movable blade body is provided with an adjacent groove adjacent to the engagement groove, and the side surface of the blade edge is provided with an adjacent groove. By providing a hooking recess into which the partition between the blade tip and the adjacent groove is hooked, it is possible to manage the size of the gap between the blade tip and the movable blade body and reduce the amount of adhesive, unlike the conventional method in which the blade tip is fixed with adhesive. This eliminates the need for management, is easy to configure, and can be firmly fixed.

が確実に防止される。BEST MODE FOR CARRYING OUT THE INVENTION In FIGS. 2 and 3, reference numeral 6 denotes a fixed blade elongated in a direction perpendicular to the drawing, and is biased by a compression spring 7. Reference numeral 8 denotes a rotary blade as a movable blade that shears the paper 9 in cooperation with the fixed blade 6. A rotary shaft (not shown) is rotatably supported on a base (not shown), and a drive connected to this rotary shaft. source (not shown)
rotates counterclockwise. In the rotary blade 8, the cutting edge portion 10 moves on a trajectory indicated by a chain line 11,
The paper 9, which is transported in a direction perpendicular to the longitudinal direction of the rotary blade 8 and the fixed blade 6, is sheared in the width direction of the paper 9. The rotary blade 8 has a movable blade main body 12 made of a cylindrical carbon steel or the like and a cutting edge part 10 made of an alloy such as tungsten carbide elongated in the direction perpendicular to the drawing, which are made of different materials. A cutting edge portion 10 is attached to the engagement groove 13. In the rotary blade 8, an adjacent groove 14 adjacent to the engagement groove 13 is formed in the movable blade main body 12, and a partition wall 15 between the adjacent groove 14 and the engagement groove 13 is pressed by a jig (not shown). and is crimped into the latching recess 10a of the cutting edge portion 10. In addition, in the rotary blade 8, the adjacent groove 14 is inclined so as to bite into the base end of the partition wall 15, thereby forming the partition wall 15 into a tapered shape that gradually becomes thicker toward the tip. In this case, the tapered partition wall 15 reliably prevents the cutting edge portion 10 from coming off.
