Description

In Patent Document 1, it may be difficult to peel off the sheet bundle from the uneven pressing surface of the needleless binding means.

Sheet binding Ji processing apparatus of the present invention, was made in order to achieve the above object, a sheet placing portion the sheet is placed, the sheet placed on the sheet placement portion the sheet aligning unit and by deforming the sheet placed on the sheet placement portion, and the binding member binding Ru by needle-free, by applying a rotational force to the sheet stapled by the stapling members for aligning said comprising binding and a member peeled peeled member, constituted by the peeling member are different members and the matching unit.

Binding Ji unit can gas relatively easily peeled from the crimping teeth, as in the prior art described above, there is no need to use an additional structure or device.

In some embodiments, peeling starvation mechanism, it is possible to directly use the sheet over sheet bundle discharge mechanism and its function, it is advantageous.

As mentioned above, without requiring additional structure or device, Ru can gas crimping teeth or al peeling the binding portion of the sheet over sheet bundle.
