ABSTRACT:
A cutting device includes a moving blade unit rotatable around a rotating shaft and inclined at a predetermined angle against a sheet feeding surface, a receiving blade unit which is movable in a direction towards the moving blade, and an elastic member for biasing a cutting edge of the receiving blade towards a cutting edge of the moving blade. Both cutting edges of the moving blade and the receiving blade are formed with a plastically deformed portion formed by press cutting. By ensuring that each second shear droop region formed in the plastically deformed portion of each cutting edge contacts the other second shear droop region of the other cutting edge, a roll-type paper inserted between the cutting edges can be easily cut.
