Sheet post-processing device and image forming device provided with the sheet post-processing device
Patent number: 10160249Abstract: A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.Type: GrantFiled: November 16, 2016Date of Patent: December 25, 2018Assignee: CANON FINETECH NISCA INC.Inventors: Kazuyuki Kubota, Eiji Fukasawa, Ichitaro Kubota, Hideyuki Kubota, Hisashi Osada, Takahiro Nakano, Hiroyuki Sorita, Junya Nakajima, Takuma Kobayashi, Takashi Saito, Isao Kondo -

Patent number: 8139999Abstract: A glue container receiving hot-melt adhesive, an applicator roll, an apparatus casing, and disposed therein, a cooling unit and its control unit, for cooling a post-cover-sheet-processed sheaf, are provided. The control unit is configured to halt the cooling unit when adhesive is being applied to a sheaf with the applicator roll, and to actuate it after adhesive application. The control unit: (1) cools the apparatus casing interior by actuating the cooling unit when a sheaf is conveyed toward a glue application position; (2) halts the cooling unit when adhesive is being applied to a sheaf conveyed into the glue application position; and (3) reactivates the cooling unit after adhesive application. Thus controlling the apparatus-internal temperature appropriately in applying a hot-melt adhesive to a sheaf, and binding the sheaf together with a cover, etc. enables secure binding adhesion in a short time frame, without bookbinding defects such as missing leaves.Type: GrantFiled: September 3, 2007Date of Patent: March 20, 2012Assignee: Nisca CorporationInventors: Katsumasa Takagi, Hiroyuki Sorita, Norihiro Ohno, Jun Kondou, Kazuyuki Kubota
