する請求項第1に記載のロータリーカツター。[Claims for Utility Model Registration] (1) A rotating blade whose shafts at both ends are rotatably supported and a cutting edge formed on the rotating circumferential surface, and a fixed blade having a cutting edge formed at the side end. and a rotary cutter configured such that the cutting edge of the rotating blade and the cutting edge of the fixed blade are brought into cross-pressure contact by the force of a spring acting on the fixed blade, the rotating blade being configured by, for example, a plate-shaped metal blade, Cut in the board thickness direction at the corner where the side surface of the rotary blade that will become the cutting edge intersects with the flat surface of the side closer to the fixed blade, so that the wall thickness at the start side is thicker and the wall thickness at the end side is thinner. The inclination angle of the inclined surface created by the difference in wall thickness is the angle corresponding to the shear angle for cutting, and the rotating peripheral surface is A rotary cutter characterized in that the cutting edge of the rotary blade is a line where the inclined surface obtained by cylindrical grinding and cut into a wedge shape intersects with the rotating circumferential surface. (2) Leave some thickness on the side of the rotary blade near the fixed blade, which will be the cutting edge, to create an inclined surface that will serve as a guide for the paper being fed. 2. The rotary cutter according to claim 1, further comprising a substantially square-shaped groove.
