<p>PROBLEM TO BE SOLVED: To provide a punching device, a post-processing device, and an image formation device, for performing punching process by rotating a punch member, efficiently with a relatively simple configuration.SOLUTION: A punching device includes a slide arm 61 which reciprocates in a predetermined direction, and a punch member 62 which performs punching process by reciprocating in punching direction while interlocking with reciprocation movement of the slide arm 61. Further, the punching device includes a rotational drive transmission member 63 which, at a timing different from the reciprocation movement in punching direction of the punch member 62, interlocks with the reciprocation movement of the slide arm 61 with the punching direction as a rotational axis direction, for rotating the punch member 62.</p> |
