Patent ID: 11745973

Abstract:
A post-processing apparatus includes a conveyor, a tray, a binder, and a binder mover. The conveyor conveys recording media on each of which an image is formed by an image forming apparatus. The tray holds the recording media conveyed by the conveyor. The binder binds the recording media on the tray with a plurality of staples in a cartridge. The binder mover includes a motor, a ratchet gear that receives a driving force of the motor to rotate in a forward direction or a reverse direction, a driving force transmitter that moves the binder toward one side in the main scanning direction as the ratchet gear rotates in the forward direction and moves the binder toward an opposite side in the main scanning direction as the ratchet gear rotates in the reverse direction, and a rotation limiter that moves between a rotation allowing position and a rotation limiting position.
