ABSTRACT:
A sorter for enclosing sheets ejected out from a recording apparatus of an electrophotographic type includes a plurality of movable trays for enclosing the sheets, and a driving unit for driving the tray so as to move the tray. In the present sorter, the driving unit widens a distance between the tray to which the sheet is enclosed and the tray adjacent to the tray and, after the sheet was enclosed to the tray, the driving unit reduces the distance between the tray to which the sheet was enclosed and the tray adjacent to the tray so as to press a curl of the sheet. By vertically moving the plurality of trays, the distance between the trays is changed and the tray to enclose the sheet is changed. Each time a predetermined number of sheets are enclosed to the tray, the plurality of trays are moved upward and, after the elapse of a predetermined time, the plurality of trays are moved downward.
