Folding tab creation device and sheet post-processing device

The present invention relates to a folded tab creating device that forms a folded tab on a sheet, and a sheet post-processing device including the folded tab creating device.

Conventionally, it has been widely practiced to provide tabs when document files are generally manually organized. For example, a sheet of a document file is created by an image forming apparatus such as a copying machine or a printer, and in a recent image forming apparatus, a multifunction machine having a plurality of functions such as a copying function, a printer function, and a facsimile function When such a multi-function peripheral is installed as an image output means for a plurality of users, a plurality of document bundles are often placed on the multi-function peripheral on the paper output tray. In this way, in order to discriminate and sort a plurality of document bundles stacked on one sheet discharge tray for each job, conventionally, there is often an operation for confirming a part or all of document contents, which is inefficient. One of the challenges is to improve simple work.

As one solution, for example, Patent Document 1 and Patent Document 2 describe providing an insert mechanism for feeding tab sheets to an image forming apparatus and inserting them between document sheets. Patent Document 3 describes that a notch is made at the end of the sheet, and this is folded back to form a tab.
