ABSTRACT:
A compact sheet stacker or sorter for a xerographic or other copier has respectively one or more upright sheet-receiving bins which are fed from below by a guide assembly which, in the case of a sorter, can be indexed from bin to bin but, in the case of a stacker is fixed. With this arrangement sheets are collected inproperly collated (1-N) order without using an active sheet inverter or conventional inverting paper path, thereby saving space. Bin plates defining the bins are shaped so as to hold sheets in a curved configuration transverse to the direction of sheet feed. The curvature imparts beam strength to the sheets enabling them to stand on edge even when the sheets extend above the tops of the bins. A stacker or sorter with relatively short bins can therefore handle a variety of sheet sizes without adjustment.
