Embodiment approach

[0025] figure 1 Shown is a schematic configuration diagram of an image forming system according to an embodiment of the present invention. Such as figure 1 As shown, the image forming system 600 includes a post-processing device 200 as a paper processing device, and an image forming device 300 that supplies paper P, which is a sheet-like medium after image formation, to the post-processing device 200 . The image forming apparatus 300 includes, for example, a copier, a printer, and the like.

[0026] The image forming apparatus 300 of this embodiment is an electrophotographic image forming apparatus including an image processing circuit, a photoreceptor, an optical writing device, a developing device, a transfer device, and a fixing device, although not shown in particular.

[0027] When the image forming apparatus 300 is a copier, the image processing circuit converts the image data read by the scanner unit into printable image data, and outputs the converted image data to t...

Abstract

The invention relates to an additional bending device, a post-processing device and an image forming system, which can press or depress a sheet bundle without damaging the end part of the sheet bundleso as to inhibit the reduction of productivity. The additional bending device comprises an additional bending mechanism which clamps a folding seam part of a sheet bundle and presses the sheet bundle. And a moving mechanism for moving the additional bending mechanism in the folding direction of the sheet bundle, wherein the additional bending mechanism includes a pair of pressing members for pressing the folding of the sheet bundle from the thickness direction of the sheet bundle, a pressing mechanism for pressing or releasing the pair of pressing members, and a driving mechanism for drivingthe pressing mechanism. The moving mechanism moves the additional bending mechanism in accordance with the size of the sheet bundle in the folding direction, and the additional bending mechanism presses the sheet bundle from the thickness direction by the pair of pressing members near one end of the sheet bundle, and depresses the pair of pressing members near the other end of the sheet bundle after being moved by the moving mechanism.

Description

technical field [0001] The invention relates to an additional bending device, a post-processing device and an image forming system. Background technique [0002] Conventionally, in a post-processing apparatus used in combination with an image forming apparatus such as a copying machine, it is known that, with respect to a sheet consisting of one or more pages, the center portion of the sheet is bound and arranged parallel to the folded sheet. The bending roller pair in the bending direction binds a saddle stitch booklet by bending the center portion of the sheet bundle. [0003] Furthermore, to enhance the crease of a saddle-stitched booklet, it is also known to add a bend by means of a roller moving along the back of the booklet. [0004] For example, the sheet bending device disclosed in Patent Document 1 has a pressing mechanism along a crease that lowers the bending height of a sheet bundle folded in half. [0005] However, in conventional post-processing devices (shee...
