And an image forming apparatus provided with a glue binding apparatus.

[0002]

2. Description of the Related Art In recent years, there has been provided a glue binding apparatus which performs a gluing process on a predetermined position of a sheet on which an image is recorded by an image forming apparatus such as a copying machine, a printer, or a multifunction machine of the above to perform bookbinding. .

[0003] As a gluing processing device, (1) a device for discharging glue on paper using a glue discharge nozzle, (2) a glue wheel is set in a glue storage box, and glue is attached to the outer periphery of the rotating glue wheel. Device that makes the outer periphery of the glue wheel contact the paper to transfer
(3) A hot melt coating device that discharges a mixture of a hot melt agent (heat fusing agent) and heated compressed air from a nozzle is used.

The bookbinding apparatus described in Japanese Patent Publication No. 59-500907 deflects a sheet conveyed in a first direction in a second conveyance direction orthogonal to the conveyance direction, and thereafter, deflects the end of the running sheet. The glue is applied linearly to the portion, and after the stacking and alignment, pressure is applied to bookbinding.

[0005]

The above-mentioned glue binding apparatus has the following problems.

(1) Since the paper transport direction is always rotated by 90 degrees before the glue application step, the paper binding direction cannot be freely selected.

(2) The paper discharge direction differs between the bookbinding mode and other modes, for example, the shift discharge mode and the direct discharge mode, and a separate discharge tray is provided, so that the size of the glue binding apparatus is increased.

(3) It is necessary to separately provide a shift sheet discharging function, which complicates the glue binding apparatus.

(4) It is not possible to glue and bind a sheet that has been subjected to center folding and a sheet that has been Z-folded.

(5) The direction in which the cover sheet is loaded into the cover sheet feeding device must be changed depending on the binding direction of the sheet bundle.

(6) It is not possible to fold a cover sheet and perform glue binding. (7) Since the paper direction changing means and the glue applying means are substantially in the same plane, the width and depth of the glue binding apparatus increase.

(8) Since the aligning and pressurizing means is disposed below the glue applying means, a portion for storing the bundle of sheets after glue binding is reduced.

The present invention solves the above-mentioned problems, improves the glue supply means and glue discharge means of the glue binding apparatus, and improves the quality of bookbinding of an image-processed sheet bundle by uniform and reliable glue application. It is another object of the present invention to provide a glue binding apparatus which realizes miniaturization and simplification of the apparatus, and has excellent operability, and an image forming apparatus provided with the glue binding apparatus.
