PAPER POST-PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a paper post-processing device capable of making a saddle-stitching position and a creasing of center-folding coincident with each other. SOLUTION: The paper post-processing device is provided with an intermediate storage tray 30 for storing a plurality of sheets of paper delivered from an image forming device such as a copying machine; a staple unit 20 for saddle-stitching a bundle of sheets of paper on a tray 30; and a center-folding unit 25 for center-folding the bundle of sheets of paper on the tray 30. Firstly, the staple is driven-in relative to the bundle of sheets of paper on the tray 30 by the staple unit 20 to apply the driving-in center-folding processing, and subsequently, the center-folding processing is applied relative to the bundle of sheets of paper by the center-folding unit 25 to put the crease at the same position as the staple position.
