    摘要: There is provided a punching unit capable of punching holes in high-performance by increasing a punching force and by rotating a punch while keeping the same basic structure with that of a prior art unit. A guide hole that guides the punch in the vertical direction is formed to have a narrow upper part, a wider narrow part and inclined surfaces between them. An actuation pin engages with a cam and the punch moves up and down to punch a hole when a cam member reciprocates. The actuation pin abuts with the inclined surface of the guide hole at the punching position, so that the punch is rotated and a cam inclined angle is reduced by an inclined angle of the guide hole, allowing a large punching force.
