Abstract: A staple removing device configured to remove a staple from a sheet bundle bound by the staple, the staple removing device includes a support part comprising a placement surface capable of placing the sheet bundle thereon, an insertion part configured to be insertable between the sheet bundle and the staple in a state in which the sheet bundle is supported on the support part, and configured to remove the staple from the sheet bundle by the insertion, and a controller configured to control an operation of the insertion part. The controller is configured to reciprocally move the insertion part multiple times between the sheet bundle and the staple in a process of removing the staple from the sheet bundle.

Abstract: An electric stapler is configured to perform binding processing including a plurality of processes. The electric stapler includes: a binding unit configured to execute the binding processing for a sheet bundle; a motor configured to drive the binding unit; and a control unit configured to control the motor. The control unit is configured to control the motor; thereby adjusting processing times of the processes so that a binding processing time after the binding processing by the binding unit starts until the binding processing is completed falls within a predetermined range.

Abstract: An electric stapler includes a clamp part, a penetration part, a clinch part, and a motor, the penetration part, and the clinch part. The electric stapler performs binding processing accompanying rotation of the motor by sequentially performing a clamping process, a penetrating process, and a clinching process. The electric stapler includes a first position detection unit that detects that a rotational position of the motor passes a first position, a braking unit that applies braking to the motor after it is detected that the motor passes the first position, a difference calculation unit that calculates a difference between a position at which the motor is stopped by the braking unit and a predetermined stop target position of the motor; and a motor control unit that moves a rotational position of the motor to the stop target position by rotating the motor forward or in reverse by the calculated difference.

Abstract: An electric stapler includes a clamp part that clamps a paper bundle, a penetration part that causes a staple to penetrate the paper bundle, a clinch part that bends the staple penetrating the paper bundle to bind the paper bundle, a driving unit that drives the clamp part, the penetration part, and the clinch part. The electric stapler performs binding processing by at least performing a clamping process of clamping the paper bundle with the clamp part, a penetrating process of causing the staple to penetrate the paper bundle with the penetration part, and a clinching process of bending the staple penetrating the paper bundle with the clinch part. The electric stapler includes a state detection unit that detects a state of the driving unit in each of the clamping process, the penetrating process and the clinching process, and a storage unit that stores the detected state.

Abstract: 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.
