摘要:
A holder and a support member for mounting a blade to a perforator are provided. The holder is composed of a blade, a two-position switching member, and a mounting member. The holder is assembled detachably to the support member along the external shape of the mounting member by operating the two-position switching member. The two-position switching member has an elastic compression member between it and the mounting member to impart elasticity to the operation, and has also an engaging section to fit into a groove in the support member, thereby ensuring the engaged state of the holder. The support member 150 includes a groove for mounting the blade and a clearance groove for punch cuttings above the groove.

A paper punch apparatus (10) comprises a bit reception plate (20) and a hole punch bit (30) disposed opposite an eccentric position of the bit reception plate (20). The apparatus (10) includes an automatic rotation mechanism (70) between the bit reception plate (20) and a main body of the punch apparatus (10), wherein the automatic rotation mechanism (70) rotates the bit reception plate (20) by a predetermined angle. The automatic rotation mechanism (70) includes a gear (23a), an engagement/disengagement member (71) that performs resilient engagement/disengagement with respect to the gear (23a) to rotate the bit reception plate (20) in one direction via the gear (23a); and a detent member (72) to prevent backward rotation of the bit reception plate (20).
