Abstract
A booklet binding apparatus including a clamp mechanism for clamping a sheet bundle, a coating member for applying adhesive to the spine surface of the sheet bundle clamped by the clamp mechanism, and an attaching and detaching mechanism for moving the coating member to and from the spine surface of the sheet bundle, wherein the attaching and detaching mechanism includes a separation mechanism which makes the coating member to be detached from the spine surface of the sheet bundle when an abnormal incident has occurred during application of the adhesive.
Description
- This application is based on Japanese Patent Application No. 2005-251003 filed on Aug. 31, 2005 in Japanese Patent Office, the entire content of which is hereby incorporated by reference.
- This invention relates to a booklet binding apparatus which produces booklets by adhesion and to an image forming system equipped with the booklet binding apparatus.
- Because of the advantages of meeting the requirements for small lot production, shorter delivery time and reduced costs, an image forming apparatus based on color electrophotographic technology has come into use in recent years to take the place of the conventional printing apparatus. The use of a booklet binding apparatus also has been considered, wherein a predetermined number of the sheets with an image formed thereon by an image forming apparatus are aligned to form a bundle of sheets and a paste is applied to the spine surface of the bundle of sheets so that a cover sheet is bonded thereon for producing a booklet.
- Among such kinds of booklet binding apparatuses, for the purpose of an enhancement of workability and quality, an apparatus which applies adhesive to the spine surface of the sheet bundle and attaches a cover sheet to the sheet bundle has been disclosed, wherein the edges of the cover sheet can be easily aligned to the edges of the sheet bundle on the opposite side of the spine portion and firmly glued to the sheet bundle (
Patent Document 1, for example). - However, if electric power to the book binding apparatus of
Patent Document 1 is shut off accidentally or involuntarily by the operator while the adhesive application is in progress, the coating roller may be stuck to the spine surface of the sheet bundle with the adhesive and it may take long time and much labor to separate the coating roller from the bundle of sheets when recovering the apparatus. Particularly, when a hot-melt adhesive is used to shorten bonding time and to obtain a strong bonding force, it may require more time and labor to melt the adhesive and separate the coating roller from the sheet bundle. - [Patent Document 1] Unexamined Japanese Patent Application Publication No. 2004-209753
