<p>PROBLEM TO BE SOLVED: To surely stop a stapler device in a prescribed bin position, also relax a shock from external force and increase durability, in a sheet after processor preventing a shock sound generated between a prime drive member and a driven member of a geneva mechanism, when external force of shock or the like is applied against the geneva mechanism in its rotational direction, also to be provided with an intermittent driving gear comprising the geneva mechanism. SOLUTION: This intermittent driving gear is formed by a geneva mechanism comprising a prime drive member 61 connected to a drive source M2 to rotate at a fixed angular speed and a driven member 62 driven by the prime drive member 61 to intermittently rotate. Here, coaxially on the driven member 62 of the geneva mechanism or on a shaft of a driven wheel G4 transmitted with rotation from the driven member 62, a torque limiter 64 is provided, the intermittent driving gear comprises the geneva mechanism formed so as to absorb turning force from external force applied to the driven member 62 by the torque limiter 64.</p> |
