Publication number: 20230257221Abstract: To reduce, at the time of sheet replenishment, breakage of a floating regulation member that regulates floating of a sheet floated by air blowing in a sheet storage apparatus that loosen stored sheets by means of air blowing. Air is blown to sheets stored in a storage part to loosen the sheets. One of a pair of side regulation members for regulating both ends of the sheets stored in the storage part has a floating regulation member for regulating floating of a sheet floated by means of air blowing. The floating regulation member is configured to be turnable in a sheet stacking direction about a rotation axis provided to one of the side regulation members on the side at which the floating regulation member is provided. A load applied to the floating regulation member differs between when the floating regulation member is turned upward and when it is turned downward.Type: ApplicationFiled: February 13, 2023Publication date: August 17, 2023Applicant: CANON FINETECH NISCA INC.Inventor: Kazunori HATAKAWA

Patent number: 8794616Abstract: A sheet post-processing apparatus includes a first unit having a guide device for guiding a sheet, a second unit having a first post-processing device for performing post-processing on the sheet, and a third unit having a second post-processing device for loading sheets and performing post-processing on the sheets in bunch form placed on the processing tray. A first coupling device is provided for coupling the first unit and at least one of the second and third units. A second coupling device is provided for coupling the second unit and the third unit. The second unit and the third unit are capable of being pulled out in the sheet carrying-out direction with respect to the first unit by releasing the first coupling device. The entire or front side of the second unit is shiftable to the first unit side with respect to the third unit by releasing the second coupling device.Type: GrantFiled: September 14, 2011Date of Patent: August 5, 2014Assignee: Nisca CorporationInventors: Satoru Matsuki, Yuji Kunugi, Ikuhiro Obata, Kazunori Hatakawa, Hiroto Akiyama, Tsukasa Kondo, Tatsuya Shimizu
