PROBLEM TO BE SOLVED: To provide a punching device capable of punching a sheet-like punched object S relatively easily.SOLUTION: A punching device 10 comprises: punch blades 12 for punching holes in a sheet-like punched object S; a punch blade moving mechanism 14, to which the punch blades are attached, for advancing and retracting the punch blades 12 toward the punched object S; and a punch blade rotating mechanism 16 for rotating the punch blades 12. When the punch blade moving mechanism 14 advances toward the punched object S, the punched object S is punched while the punch blades 12 are rotated by the punch blade rotating mechanism 16 interlocking with the movement of the punch blade moving mechanism 14.SELECTED DRAWING: Figure 1 |
