To provide a stapler in which a staple leg of a nonmetal staple can be reliably bent with a small number of components and a simple configuration so as to reduce a cost. A stapler includes a penetration mechanism and a bending mechanism. Hole parts are provided in a pair of cutting blades of the penetration mechanism. The bending mechanism includes first and second bending members which protrude from the hole parts toward between the pair of cutting blades to bend a pair of staple legs, guide surfaces which guide the first and second bending members, and a slide member which drives the first and second bending members. The first and second bending members are provided between the guide surfaces and the slide member.

A stapler includes a penetrating part including a pair of cutting blades to form holes in a workpiece and to cause leg portions of a staple to penetrate the workpiece, an operating member, and a bending part configured to bend the leg portions. The bending part includes a bending member configured to bend the leg portions of the staple, and a driving force transmitting section configured to transmit an operation of the operating member to the bending member.

A flat clinch assembly fits upon or within a base of a stapling device. The assembly preferably includes a slot with extended resiliently biased arms or toggles, where a rest position has the arms at or near a level of a working surface. An ejecting staple deflects and energizes the arms to cause the arms to rotate and create a clearance recess whereby points of the staple legs slide inward along the anvil. A restorative bias acting on the arms causes the arms to rebound to a rest position and to bend the legs upward. The legs thereby are normally pressed flat against the back sheet of a paper stack at the working surface. The arms or toggles are lightweight whereby the inertia of a fast-moving staple moves the arms or toggles. The toggle may include an upward facing staple leg guide channel.
