Abstract
A pasting binding apparatus for binding a bundle of sheets comprises a paste coating device to coat a paste in a form of a line onto a binding side of a sheet being conveyed on a conveying passage in a conveying direction by a conveying device; a pressing device located above the paste coating device and to stack the sheet coated with the paste onto the bundle of sheets and to press the sheet onto the bundle of sheets; and the conveying device to convey the sheet to the paste coating device and to the pressing device.
Claims33
A pasting binding apparatus for binding a bundle of sheets, comprising:
- a conveyor which conveys plural sheets serially on a conveying passage in a conveying direction;
- a paste coating device which coats a line of paste onto a binding side of a first surface of each sheet conveyed by the conveyor;
- and
- a binding device including:
- a stacking device which successively receives the sheets from the paste coating device and stacks the plural sheet in a bundle in a manner such that the coated first surface of each of the sheets faces downward;
- and
- a pressing device which brings a pressing member in contact with a non-coated second surface of an uppermost sheet of the bundle of sheets so as to press the uppermost sheet onto the bundle of sheets;
- wherein the binding device is located above the paste coating device and the conveying passage, and the binding device is arranged such that the coated first surface of the sheets faces downward in the binding device.

An image forming apparatus, comprising:
- an image forming unit which forms images on plural sheets;
- and
- a pasting binding unit for binding a bundle of the sheets bearing the images formed by the image forming unit,
- wherein said pasting binding unit comprises:
- a conveyor which conveys the sheets serially from the image forming unit on a conveying passage in a conveying direction;
- a paste coating device which coats a line of paste onto a binding side of a first surface of each sheet conveyed by the conveyor;
- and
- a binding device including:
- a stacking device which successively receives the sheets from the paste coating device and stacks the plural sheet in a bundle in a manner such that the coated first surface of each of the sheets faces downward;
- and
- a pressing device which brings a pressing member in contact with a non-coated second surface of an uppermost sheet of the bundle of sheets so as to press the uppermost sheet onto the bundle of sheets;
- wherein the binding device is located above the paste coating device and the conveying passage, and the binding device is arranged such that the coated first surface of the sheets faces downward in the binding device.
