摘要:
A sheet sorting device for a sheet discharging apparatus which has a sheet discharging tray which receives discharged sheets when the sheet sorting device is not attached to the sheet discharging tray. The sheet sorting device includes a movable tray which is configured to receive sheets discharged from the sheet discharging apparatus and configured to reciprocate in a reciprocating direction substantially perpendicular to a sheet conveying direction of the sheet discharging apparatus by a predetermined stroke necessary for sorting sheets. The sheets are sorted by reciprocating the movable tray in the reciprocating direction. The sheet sorting device is configured to detachably attached to the sheet discharging tray.
