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 sheet post-processing apparatus includes an output tray on which a sheet ejected from a sheet outlet is stacked; a wall disposed downstream from the output tray in a sheet ejection direction; and an alignment member configured to contact and move the sheet on the output tray, to bring a rear end of the sheet in the sheet ejection direction into contact with the wall for alignment. The alignment member is selectively set at three positions of: an alignment position protruding beyond the wall toward the output tray to contact the sheet on the output tray; a withdrawn position inward of the wall; and a home position between the alignment position and the withdrawn position.
