Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a copying machine having a bookbinding function, and particularly to a copying machine having a bookbinding function capable of punching file binding holes in saddle-stitched sheets. [Prior Art] Conventionally, when copying multiple copies of multiple originals, a sorter, or T-seam, is used to align the pages of the copied sheets, and a stitcher or the like is used to align the pages of the sheets. Edge-stitching was used to bind the edges. However, when large-sized sheets such as 80 and ['171 are edge-stitched, it takes up a large amount of space when spread and is difficult to handle. In some cases, in order to save space when storing, the *i1 bound paper is sometimes folded in half at the center, but this J: uni paper is folded all at once, but it does not look good when stored. Because of the folding process, it becomes difficult to see the information on the folded part when making a double-page spread. Therefore, after the copying process is completed by the copying machine, the paper is folded in half at the center, and the folded part is overlapped by the number of sheets in one part. It is possible to make a double-page booklet by binding it with a binding device, but when it is saddle-stitched in a double-page booklet like this, there are binding holes for files when it is filed. However, if these binding holes are not positioned symmetrically with respect to the folding process, the position of the binding holes will shift when filing, making it difficult to bind or binding will not be possible. [Object of the Invention] The present invention has a bookbinding function in which the binding shell can be used to punch a file binding hole at an accurate position when binding at the crease of half-folded paper. The purpose of this invention is to provide a binding hole punching device for files installed in copying machines.
