A medium processing apparatus includes a conveyor, a receptacle, an aligner, a crimp binder, and circuitry. The conveyor conveys a medium. The receptacle holds the medium. The aligner contacts a downstream end of the medium and aligns a position of the medium in a conveyance direction of the medium. The crimp binder faces the downstream end of the medium to press and deform a binding position on media of which the position is aligned, to bind the media. The aligner and the crimp binder are movable in a main scanning direction orthogonal to each of the conveyance direction and a thickness direction of the medium. When determining that the aligner overlaps the binding position when the receptacle is viewed in the thickness direction, the circuitry moves the aligner in the main scanning direction away from the binding position and causes the crimp binder to crimp and bind the media.

Medium processing apparatus, image forming system, medium processing method, and non-transitory recording medium

A medium processing apparatus includes a conveyor, a tray, a binder, a mover, and a switcher. The switcher includes a first passage, a second passage, and a movable wall. The movable wall guides a guided portion of the binder to the second passage when the guided portion moving along the first passage from an end side to a center side contacts the movable wall; causes the guided portion to pass when the guided portion moving along the second passage from the end side to the center side contacts the movable wall; guides the guided portion to the first passage when the guided portion moving along the second passage from the center side to the end side contacts the movable wall; and causes the guided portion to pass when the guided portion moving along the first passage from the center side to the end side contacts the movable wall.

Medium processing apparatus and image forming system incorporating same

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.
