A post-processing apparatus which can respectively balance convenience of user using a manual stapling and convenience of user using an online stapling is provided. The finisher includes a stapler for performing predetermined post-processing on a sheet received and a control unit. The finisher also includes a stapler moving motor which moves the stapler to a position where first processing or second processing is performed. In the first processing, the predetermined post-processing is performed on a sheet which is conveyed from an image forming apparatus. In the second processing, the predetermined post-processing is performed on a sheet which is manually inserted.

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.

A stapling apparatus includes a stapler, a driver to move the stapler, and a guide part to define a moving path along which the stapler is to move in response to selection of the moving path among a plurality of moving paths along which the stapler is movable.
