Document Type and Number:
WIPO Patent Application WO/2021/225043
Kind Code:

Abstract:
The purpose of the present invention is to prevent interference between a hole edge brim of a die hole and a punching blade when the punching blade makes reciprocating movement. The punching blade (7) includes: a cylindrical body part (71) that extends along a punching axis; and a blade section (72) that is formed at one end of the body part (71) and that has a blade tip for making a hole in a sheet. A movement mechanism (7M) causes the punching blade (7) to make reciprocating movement along the punching axis. A guide member (8) has a guide hole (81) which has a hole center on the punching axis and through which the punching blade (7) can be inserted, and guides the reciprocating movement of the punching blade (7). A die member (9) is disposed so as to oppose the guide member (8) with a conveyance path of the sheet therebetween and has formed thereon a die hole (91) that has a hole center on the punching axis and that tolerates insertion of the blade section (72) in the punching blade (7). In the punching blade (7), the outer diameter of the blade section (72) is less than the outer diameter of the body part (71).
