ABSTRACT:
The present invention discloses a sheet processing unit which can control the timing in conveying successively fed sheets to a sheet ejecting mechanism in accordance with operating conditions. The sheet processing unit comprises a sheet overlapping mechanism which overlaps successively fed sheets together, a conveying mechanism which conveys the sheets from the sheet overlapping mechanism, an ejecting mechanism which ejects the sheets conveyed by the conveying mechanism, and a control unit which electrically controls operations of the sheet overlapping mechanism, the conveying mechanism, and the ejecting mechanism. The control unit changes the number of sheets to be overlapped together at the sheet overlapping mechanism in accordance with information on the conditions for operation of the sheet processing unit inputted from an input unit.
