Paper sheet processing apparatus and image forming system

摘要

A paper sheet processing apparatus includes a supporting unit which supports a bundle of stacked paper sheets, a binding processing unit which performs binding processing at least at two binding positions on the bundle of paper sheets, a pair of hold-down units which hold down the bundle of paper sheets, and a moving unit which moves at least one hold-down unit from among the pair so as to separate from the other hold-down unit in a direction in which the at least two binding positions are aligned in the bundle of paper sheets. In the paper sheet processing apparatus, the binding processing unit performs the binding processing between the pair of hold-down units on the bundle of the paper sheets following moving of at least one hold-down unit among the pair of hold-down units while the pair of hold-down units is holding down the bundle of the paper sheets.

主权项

1. A paper sheet processing apparatus, comprising:
a supporting unit which supports a bundle of stacked paper sheets; a binding processing unit which performs binding processing at least at two binding positions on the bundle of paper sheets; a pair of hold-down units which hold down the bundle of paper sheets by pressing the bundle of paper sheets against the supporting unit; a moving unit which moves at least one hold-down unit from among the pair of hold-down units so as to separate said at least one hold-down unit from the other hold-down unit in a direction in which the at least two binding positions are aligned in the bundle of paper sheets; and a control unit which controls the binding processing unit, the pair of hold-down units and the moving unit, wherein the control unit is configured to perform operations comprising:
stacking a plurality of paper sheets on the supporting unit to form the bundle of paper sheets;holding down the bundle of paper sheets formed on the supporting unit by the pair of hold-down units;moving, by controlling the moving unit, said at least one hold-down unit of the pair of hold-down units while the pair of hold-down units are holding down the bundle of paper sheets on the supporting unit; andperforming the binding processing between the pair of the hold-down units on the bundle of paper sheets by the binding processing unit.
