Apparatus for processing sheets and apparatus for forming images provided with the apparatus for processing sheets

By retracting the coating position of the previous sheet when the next sheet is transported into the stacking section, the problems of bonding errors and device enlargement in the prior art are solved, and a compact sheet processing device is realized that can be processed in one place. Switching and operation of gluing and pin binding takes place within the frame.

Abstract

A sheet folding apparatus includes a retract path that is positioned on the upstream side of a stacker section for collecting sheets and that branches off from a transport path to enable a sheet carried in the stacker section to be transported in a direction opposite to a carry-in direction, an adhesion unit that is positioned in a junction position of the transport path and the retract path to bond sheets by applying an adhesive, a staple binding unit that binds sheets collected in the stacker section with a staple, and a folding processing section that folds sheets bound with the unit. The retract path is a path for retracting an application position of the preceding sheet with the adhesive applied, in carrying a next sheet in the stacker section, and the staple binding unit is disposed in the stacker section between the adhesion unit and the folding processing section. The apparatus allows adhesion and needlebinding of the sheet materials with compact structure since the sheet materials are accommudated in one frame.

Description

technical field [0001] The present invention relates to a processing device that binds sheets delivered from image forming apparatuses such as copiers and printers to form a bundle, and folds the bundle at a predetermined folding position as required, and relates to a processing device that can be made into a sheet that can be bonded with an adhesive as desired. A device for any one of a combined sheet booklet and a needle-bound sheet booklet. Background technique [0002] In general, there are widely known processing apparatuses that align and staple sheets delivered from an image forming apparatus, or fold them into a booklet. Also disclosed is a device that folds a booklet in half after the sheets are bound with a staple as necessary, and folds the sheets together with glue or an adhesive. [0003] For example, in Japanese Patent No. 5168474, a unit storage section is provided that can alternatively store a needle-binding unit for needle-binding a sheet bundle and a shee...
