<p>PROBLEM TO BE SOLVED: To provide a paper post-processing device capable of center binding processing and center folding processing, without damaging paper, when the center binding processing paper number is many or even when a paper thickness is thick, by executing center binding processing without using a metallic needle.SOLUTION: Among a pair of paper 5 positioned in both end parts in the overlapping direction of a paper bundle 6, one paper 5 is processed so as to have an engaging piece 5d. The engaging piece 5d is not provided in the other paper 5 for constituting the paper bundle 6. As a first stage of a folding process, the engaging piece 5d is folded and inserted into a first hole 5a of the other paper 5. Next, the engaging piece 5d is folded along an upper surface of the paper bundle 6, and then, is inserted into a second hole 5b. The tip part side of the engaging piece 5d is run along an under surface of the paper bundle 6, and thereby, the paper bundle 6 is bound by the engaging piece 5d.</p> |
