More Information
Summary:A paper processing device includes a processing unit, a paper ejection roller, a sorting mechanism, a paper overlapping mechanism, and a control unit. The processing unit performs predetermined processing upon sheets of paper being conveyed one at a time along a paper conveyance direction. The roller discharges the sheets in the paper conveyance direction, after completion of processing by the processing unit. The sorting mechanism shifts the roller to and fro between an initial position and a sorting position in a direction orthogonal to the paper conveyance direction. The overlapping mechanism superimposes, between the processing unit and the roller in the paper conveyance direction, a predetermined number of sheets of paper upon which processing has been completed. The control unit superimposes a predetermined number of sheets of paper by operating the overlapping mechanism, before shifting the roller from the initial position to the sorting position with the sorting mechanism.
