Claims

[Claims for Utility Model Registration] 1. The side surfaces of the peripheral edges of circular blades that rotate in opposite directions are in contact with each other, and a sheet-shaped object to be cut that passes between the peripheral edges of the blades is cut into a predetermined shape by the blades. A cutting device configured to cut to a width, at least one of the blades being urged in the direction of its central axis by an elastic means and held by a blade holding means,
A cutting device characterized in that the one blade and the blade holding means are fixed to each other in the circumferential direction by concave-convex fitting. 2 A peripheral edge portion of the disk comprising a disk-shaped blade that rotates in a predetermined direction and a blade holding means for holding the blade, the peripheral edge side surface of the blade rotating in a direction opposite to the aforementioned direction. It is used to cut a sheet-shaped object to be cut on the sliding contact surface that slides on the side surface and passes through this sliding contact area, and the blade is urged in the direction of its central axis by an elastic means to A cutting tool assembly configured to be held by a blade holding means, wherein the blade and the blade holding means are fixed to each other in the circumferential direction by concave-convex fitting. Tool assembly.
