An electric stapler is configured to perform communication with a sheet processing apparatus. The electric stapler includes: a binding unit configured to execute binding processing for a sheet bundle; a motor configured to drive the binding unit; a control unit configured to control the motor; and a communication interface configured to perform communication with the sheet processing apparatus. The control unit controls the motor to execute the binding processing by the binding unit when a predetermined signal is received from the sheet processing apparatus via the communication interface.

The cutting portion includes a pair of introduction portions allowing the staple legs penetrating the sheets of paper to be introduced therein, a pair of cutting members configured to cut the staple legs introduced in the introduction portions, and a discharging path configured to discharge cut staples cut by the cutting members. The discharging path includes a temporary receiving portion for the cut staples provided between the pair of introduction portions. The temporary receiving portion includes a pair of inlet portions respectively provided on side surfaces thereof opposing the introduction portions. The pair of inlet portions are configured to allow the cut staples cut by the cutting members to enter therein.

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.

A stapler includes a staple striking portion configured to strike a staple to penetrate sheets of paper and a clincher portion configured to bend staple legs of the staple penetrating the sheets of paper. The clincher portion includes a pair of clinchers. The pair of clinchers are configured to perform a first operation and a second operation. In the first operation, the pair of the clinchers move along a surface direction of the sheets of paper to approach each other. In the second operation, the pair of clinchers move to approach the sheets of paper after the first operation.

A stapling apparatus including a holding portion that receives and holds a plurality of mediums, a first matching portion positioned downstream of the holding portion, a paddle that applies sending force to the mediums so that leading edge sides of the mediums reach the first matching portion, a stapler that binds the mediums, the leading edge sides of the mediums having been matched by the first matching portion, a folding mechanism portion that folds the mediums that have been bound by the stapler. In the stapling apparatus, the first matching portion is configured to move and is configured to transport the mediums to a performing position of the stapler and a performing position of the folding mechanism portion by moving, and a position where the paddle applies sending force to the mediums differs according to lengths of the mediums in a transport direction.

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.
