Patent number: 10556458Abstract: Single perforating unit is enabled to perforate for file binders and to cut milling grooves, while with a simple structure file-binder storage and booklet-binding can be carried out reliably. Configurations include: a convey-in path for sequentially transferring sheets; a stacker for collating into bundles sheets from the convey-in path; and an adhesive-layer applicator for adding an adhesive layer to the spine-closure edge of sheet bundles from the stacker. A perforating unit is provided in along the convey-in path, and a control unit for controlling position and/or number of perforations made by the perforating unit is provided with (1) a first operation mode in which it effects the punching of a predetermined number of holes in the edge of sheets, and (2) a second operation mode in which it effects the formation of a predetermined number of crenulated grooves in the edge of sheets.Type: GrantFiled: November 13, 2015Date of Patent: February 11, 2020Assignee: Nisca CorporationInventors: Sei Takahashi, Hideki Orii, Naoki Ueda, Keiichi Nagasawa, Kazuyuki Kubota

Patent number: 7422205Abstract: An original feeding apparatus includes a feeder tray for stacking originals, a separating device for separating the originals into a single sheet, and a feeding device for feeding the original to the separating device. The feeding device is raised or lowered between a feeding position where the feeding device contacts an uppermost original stacked on the feeder tray, and a retracted position where the feeding device is separated from the uppermost original. A drive device and a control device are disposed for raising and lowering the feeding device. The control device adjusts a rotating speed of the drive device for raising and lowering the feeding device according to a reading mode, so that the feeding device is lowered at a different speed to touch the uppermost original.Type: GrantFiled: April 8, 2005Date of Patent: September 9, 2008Assignee: Nisca CorporationInventors: Mamoru Akiyama, Eiichi Kubo, Sei Takahashi, Junko Kurakane
