There is provided a stapler including: a driving portion that drives a staple into a sheet bundle; a clinch portion that bends a leg portion of the staple driven into and penetrating the sheet bundle; a table link that supports the clinch portion at a position facing the driving portion and move the clinch portion in a first direction where the clinch portion separated from and brought into contact with the driving portion; a motor that drives the driving portion; and a regulation portion that moves in a second direction intersecting the first direction while abutting against the table link and regulate a movement of the clinch portion in a direction away from the driving portion. A position where the regulation portion abuts against the table link changes in a direction toward the clinch portion as the clinch portion and the driving portion are separated from each other.

There is provided a staple cartridge, on which a refill is configured to be mounted, the refill including a refill main body configured to accommodate therein a plurality of staple sheets in a stacked state and having a discharging port for discharging the staple sheets, and a staple presser configured to be placed on the stacked staple sheets so as to move in a stacking direction of the staple sheets as the staple sheets are discharged through the discharging port and an amount of the staple sheets is reduced. The staple cartridge includes a mount portion, on which the refill is configured be removably mounted, and a displacement member provided on the mount portion and configured to abut against the staple presser to be displaced in accordance with a position of the staple presser in a state where the refill is mounted on the mount portion.

An electric stapler includes a binding unit configured to perform binding processing on a sheet bundle by sequentially executing a clamping process of clamping the sheet bundle, a penetration process of penetrating a staple through the clamped sheet bundle, and a clinching process of pressing leg portions of the staple penetrating through the sheet bundle, a motor configured to drive the binding unit, and a controller configured to control the motor. The controller is configured to control the motor to execute the clamping on the sheet bundle or the pressing on the leg portions multiple times in the clamping process.

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.
