Finisher

摘要

A finisher includes an additional-working tray and a leading edge stopper and trailing edge stopper for aligning folded and unfolded sheets fed into the additional-working tray. The leading edge stopper contacts a leading edge of each sheet when it is fed into the additional-working tray. The trailing edge stopper is movable relative to the additional-working tray in accordance with a sheet length. The trailing edge stopper is adapted to align one or more sheets received in the additional-working tray relative to a discharge direction.
