Description

  The present invention relates to a sheet file processing apparatus for storing a sheet in a sheet file for storing a sheet such as a document between opposed sheet pieces, and an image forming system including the sheet file processing apparatus.

In a sheet file such as a clear file, the two edges of the opposite sheet pieces are opened, and the other edges are connected to enable the loading and unloading of documents such as documents. Organizing documents and collecting documents It is used for.
The sheet file is usually manufactured industrially by folding one sheet and bonding one edge piece of the opposing sheet piece. Further, in the manufacture of Z-folded postcards and the like, a process of manufacturing a file integrally with a storage sheet sandwiched between them is adopted (see, for example, Patent Document 1). However, when storing sheets in the sheet file, a Z-folded postcard is used. Such a manufacturing process is difficult to adopt. When the sheets are stored in the sheet file, as shown in FIG. 6A, the open edges 41 and 41 of the sheet file 40 manufactured in a separate process are opened, and the sheet bundle 45 is directed to the open edges 41 and 41. It is a practical method to store the sheet 45 in the sheet file 40 by moving the sheet 45.
