Sorter-finisher

摘要

In a sorter-finisher with a sorting and stapling functions, the sheets ejected from a copying machine are transported and stored one by one into bins which are movable in the vertical direction along a guiding member, after taking out from each of the bins, the sheets are stapled by a stapling device. The guiding member, for preventing sheets on the bins from sliding down, have a first opening through which sheets ejected from the copying machine are fed onto one of the bins located opposite to the first opening and a second opening through which sheets held on one of the bins located opposite to the second opening are taken out. A first gate member provided at the first opening is movable from a closing position where the first gate member closes the first opening to an opening position where the first gate member is out of the first opening. A second gate member provided at the second opening is movable from a closing position where the second gate member closes the second opening to an opening position where the second gate member is out of the second opening.
