Sorter incorporating a stapler.

摘要

A sorting apparatus is provided for sorting and stapling sheets discharged from an image forming apparatus. A plurality of vertically driven sheet bins (23, 73) are provided along with a stapler (25) for stapling the sheets while stored in the bins (23, 73). A pair of lateral guides (261, 262) move stacks of sheets in the sheet width direction within the bins. The lateral guides are adapted to abut on either side of the sheets and to position the sheets from an original position into a stapling position in front of the stapler (25).
