Patent number: 7575229Abstract: The sheet processing apparatus has a stapling unit which staples a sheet bundle by clinching the sheet bundle, of which sheets sequentially enters an opening between a first stapling part and a second stapling part and are then stacked, and a controller which controls the stapling parts. When executing a stapling process of the sheet bundle, an opening distance between the stapling parts before starting a stapling operation becomes narrower than an opening distance set till the last sheet of the sheet bundle enters (approaches) between the stapling parts. This contrivance enables reduction of the time required for the stapling process of the sheet bundle and an improvement of the productivity irrespective of the number of points for the stapling process without scaling up the apparatus, causing any complicated configuration of the apparatus and increasing the costs.Type: GrantFiled: July 31, 2008Date of Patent: August 18, 2009Assignee: Canon Kabushiki KaishaInventor: Hideki Kushida

Publication number: 20090140483Abstract: When a sheet bundle is being conveyed by any one pair of plural pairs of rollers independently movable toward and away from the bundle sheet, before the bound portion of the sheet bundle passes the pair of rollers, the pair of rollers on the downstream side nearest to the bound portion are separated from the sheet bundle, and the pairs of rollers more downstream than that pair convey the sheet bundle. Thereby, it happens less often that the pairs of rollers gather the air collected between adjacent ones of the sheets of the sheet bundle to the bound portion to thereby cause a slack to the sheets, and the occurrence of wrinkles or twists in the sheet bundle can be reduced. Also, the pair of rollers are separated from the sheet bundle before the bound portion passes the pair of rollers, whereby it happens less often that the pair of rollers are damaged by the bound portion, and the sheet bundle can be conveyed smoothly.Type: ApplicationFiled: January 23, 2009Publication date: June 4, 2009Applicant: CANON KABUSHIKI KAISHAInventors: HIDEKI KUSHIDA, TARO IKEDA, HIROAKI TAKAGISHI, KENICHI HAYASHI, TOMOKAZU NAKAMURA, WATARU KAWATA, HIROMASA KATAYAMA

Patent number: 7540489Abstract: The position of a sheet accommodated in a sheet storage portion is restricted by a restricting member provided movably on a sheet storage portion. This restricting member has a holding portion which is movable freely and is attached detachably to the sheet storage portion so as to hold the restricting member at a restricted position corresponding to a sheet size. The end portion of the sheet whose rear end position is restricted is pressed from above by a pressing member provided movably in a vertical direction on the end portion restricting member. Then, to move the restricting member, an operation portion is operated and the holding portion is moved in a direction of releasing the engagement and the pressing member is raised upward of accommodated sheets.Type: GrantFiled: October 10, 2007Date of Patent: June 2, 2009Assignee: Canon Kabushiki KaishaInventor: Hideki Kushida
