A waiting tray is provided at some midpoint of a conveying path, and a sheet is caused to be in a waiting state when a post-process is required. Before performing the post-process, a processing tray receives the sheet conveyed from the waiting tray and the sheet conveyed from a conveying path without passing through the waiting tray. At this point, waiting tray parts are moved toward a direction in which the waiting tray parts are separated from each other, and a bundle of paper starts fall-down. When the bundle of paper falls down, the waiting tray parts are moved toward the direction in which the waiting tray parts are brought close to each other, and an alignment member performs alignment in a transverse direction of the bundle of paper.
