Problems solved by technology

[0004] In the needleless binding process, if the number of sheets to be stapled increases, the binding force that binds the sheets of the sheet bundle decreases, so there is a limit to the number of sheets that can be stapled by one binding process.

Embodiment Construction

[0082] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the drawings, the same reference numerals are assigned to similar components throughout the specification.

[0083] In addition, in this specification, "offset conveyance of the sheet bundle" means that the sheet bundle formed by accumulating the sheets loaded onto the processing tray from the paper discharge port is moved in a direction perpendicular to (or intersecting) the sheet conveyance direction. Move in the direction (as far as possible to move to the side), and "offset" refers to the amount of movement. In addition, "alignment of sheet bundles" refers to aligning a plurality of sheets of different sizes loaded from the paper discharge port onto the processing tray according to a predetermined standard (for example, the direction perpendicular to the sheet conveyance direction as the processing tray, i.e. The center reference o...

Abstract

The present invention is to provide a sheet bundle binding device capable of easily removing some sheets from a sheet bundle that has been subjected to staple-free binding. A corner Sc of a first sheet bundle Sb1 which is accumulated on a processing tray is subjected to proper binding by using a staple needle by a staple binding unit 70. Then, a corner of a second sheet bundle Sb2 obtained by accumulating additional sheets on the first sheet bundle is pressed and deformed between crimping toothed parts of a staple-free binding unit to temporarily bind the second sheet bundle. Thus, the additional sheets can easily be removed from the second sheet bundle.

Description

technical field [0001] The present invention relates to, for example, a sheet bundle binding processing device for automatically performing needleless binding processing by forming a plurality of sheets conveyed from an image forming apparatus into a bundle, and further relates to an image forming system including the sheet bundle binding processing device. Background technique [0002] In recent years, in addition to a needle binding device that stacks a plurality of sheets and nails them into a metal needle to bind a bundle of sheets, a needleless binding device that clamps the stacked sheets to 1 The sheets are pressed against each other by strongly pressing between the concavo-convex shaped pressing teeth to staple the sheet bundle. On the other hand, sometimes you want to remove only a part of the sheets from the stapled sheet bundle, but this operation is very troublesome regardless of whether it is needle binding or needleless binding, and the sheets with the sheet bu...
