Sheet sorting apparatus

摘要

An apparatus for sorting sheets (P) on a tray (T1,T2) in which a stacking position of sheets is changed for each set number of sheets to one of different stacking positions on the tray, includes a movable pressing member coming in contact with a discharging roller (405) on its low position so that a discharging speed of the sheet is reduced, a movable lower guide plate so that the lower guide plate is positioned lower than a upper portion of the discharging roller on its low position; a sensor to detect a passage of a sheet; and a driving device to move the lower guide plate and the pressing member in response to a signal from the sensor.
