Abstract
Abstract A sorter for use with a copier and others and having a function of binding a stack of copy sheets. The sorter includes a single stapler which is shared by all bins of the sorter, and a single bin drive unit adapted to move any of the bins loaded with copy sheets to a prescribed position where the stapler is to drive a staple. The stapler and the bin drive unit are moved in an interlocked motion to positions which correspond to the respective bins, thereby sequentially binding copy sheets which are stacked in the bins.
