[0052] The main object of the first embodiment is to achieve the above-mentioned first object of the present invention.

[0053] As described above, with the conventional sheet processing apparatus, when binding by saddle stitching or center folding, if the rear end edges of the pages become messy, this causes a problem that the misalignment of the end edges of the bound sheet stack will It becomes apparent that this ultimately results in a poorer appearance. The following will refer to Figure 1A , Figure 1B and figure 2 Be explained.

[0054] Such as Figure 1A As shown, with respect to the conventional sheet processing apparatus, when the end edges of the sheets S slid into and accommodated in the pawl members T are not subjected to the binding process, the end edges thereof will rise with the movement of the pawl members T. Here, when the page thickness based on the number of pages is close to the distance L of the inner bottom surface of the claw member T, the moveme...

Abstract

The present invention relates to a sheet processing device for an image forming apparatus, which is configured to be capable of preventing misalignment of end edges of sheets taken out and conveyed from an intermediate tray, and reliably preventing misalignment in post-processing steps of the sheets. So-called end edge shifting, thereby preventing a poor appearance in a bookbinding process in which the pages are used as image-formed recording media. The page folding apparatus enables the user to easily adjust the misalignment of the folding line of the page during actual use in the middle folding processing step of the page used as the image-formed recording medium.

Description

technical field [0001] The present invention relates to a sheet folding device for folding a sheet-shaped recording medium, a sheet processing device having the sheet folding device and binding by saddle stitching or the like, and a sheet folding device or sheet processing device having such a sheet folding device An imaging device of a device such as a photocopier, a printer, a facsimile device, and a printing press. Background technique [0002] In image forming devices such as photocopiers, printers, facsimile devices, and printing machines, an image is formed by developing a latent image carrier such as a photoconductive drum or a photoconductive belt with a developer such as toner, and the image is transferred to a recording on a medium (hereinafter referred to as paper or page for convenience). [0003] In addition to the case where only a single image-formed page is output from the image forming device, there are cases where a plurality of image-bearing pages are sta...
