Abstract

A stapler in which staple legs extending through the material to be bound by more than a given length are cut by cooperation between a movable and fixed cutting member. The movable member is moved in a direction orthogonal to the penetrating direction of the staple legs by rotation of a cam which also causes a driver to drive the staple through the material and also clinches the cut staple legs.
