Abstract (en)
A sheet post-processing device (20) comprises: a processing tray (30); a discharge tray (50); and a pair of discharge rollers (29). The pair of discharge rollers (29) is constituted by a discharge roller (29a) which contacts the uppermost surface of sheets stacked in the processing tray (30), and a discharge roller (29b) which contacts the lowermost surface of the sheets stacked in the processing tray (30). The sheet post-processing device (20) discharges a sheet from the processing tray (30) to the discharge tray (50) by rotating the pair of discharge rollers (29) in the forward direction, and causes the sheet to be drawn into the processing tray (30) by rotating the discharge roller (29a) in the reverse direction in a state in which the rotation of the discharge roller (29b) is stopped.
