Patent number: 8027629Abstract: An image forming apparatus of the present invention is arranged so that plural sheets of paper are conveyed to a main conveying path and a sub-conveying path at the time of double-side image formation. In performing double-side image formation jobs on plural sets of sheets of paper, a sequence control section makes a change of sequences for image formation so that a post-process for the previous job can be performed during image formation of the next set. With this, in performing double-side image formation jobs on plural sets of sheets of paper in an image forming system constituted by an image forming apparatus and a post-processing apparatus, images can be formed in succession without suspending image formation of the next set to allow post-processing time for the previous set. This makes it possible to achieve a system with high job efficiency.Type: GrantFiled: December 3, 2008Date of Patent: September 27, 2011Assignee: Sharp Kabushiki KaishaInventor: Kenji Tanaka

Patent number: 8027630Abstract: A sheet processing apparatus which enable users to easily set the cutting amount of sheets according to the intended purpose of use. A folding unit folds the sheets. A cutting unit cuts off ends of the folded sheets. A setting unit sets details of processing of the sheets to be executed at least by the center-folding unit and the cutting unit. The setting unit is capable of selecting a first cutting amount-setting mode in which a cutting amount is set using a cutting width of the at least one end, and a second cutting amount-setting mode in which the cutting amount is set using a sheet size which the sheets should have after being cut. The setting unit sets the cutting amount in a selected one of the first cutting amount-setting mode and the second cutting amount-setting mode, when setting details of processing of the sheets to be executed by the cutting unit.Type: GrantFiled: July 2, 2007Date of Patent: September 27, 2011Assignee: Canon Kabushiki KaishaInventors: Takayuki Fujii, Tsuyoshi Moriyama

Patent number: 8023880Abstract: The disclosure concerns a standby tray for making a sheet at the position above a processing tray. The sheet on the standby tray is dropped and supplied onto the processing tray. The upper end of the center area of a shutter supporting the rear end of the sheet on a sheet discharge tray which is slidable to the sheet discharge section of the standby tray or processing tray is made lower than the upper end of the peripheral area of the shutter. Movable portions of the shutter are extended when the sheet discharge tray is slid to close the sheet discharge sections of the processing tray and/or standby tray.Type: GrantFiled: December 26, 2006Date of Patent: September 20, 2011Assignee: Toshiba Tec Kabushiki KaishaInventors: Yasunobu Terao, Mikio Yamamoto, Yoshiaki Sugizaki, Hiroyuki Taki

Publication number: 20110222944Abstract: A paper transporting device includes a driving roller member, a driven roller member, a first guiding member and a second guiding member. The driving roller member is rotated. The driven roller member is rotated in contact with the driving roller member. The first guiding member is disposed on a driving roller member side, and guides a paper to a contact portion in which the driving roller member and the driven roller member are in contact with each other. The second guiding member is disposed on a driven roller member side, and guides the paper to the contact portion. The second guiding member partially protrudes inward in a radial direction of the driving roller member from an outer peripheral surface of the driving roller member at a downstream side in a paper transporting direction of the contact portion.Type: ApplicationFiled: September 3, 2010Publication date: September 15, 2011Applicant: FUJI XEROX CO., LTD.Inventors: Yasuki TANAKA, Yukihiro ICHIKI, Motoyuki YAGI, Tahei NAKAMURA

Patent number: 8011650Abstract: There is set sheet post-processing (SPP) information having a post-processing-edge (PPE) code, a staple code and a punch code. When the staple code indicates one end of the PPE and the PPE is rotated towards the one end by 90° with respect to the center of the sheet, the SPP code is updated, and the staple code SC is updated to indicate the other end of the PPE. Referring to a table, it is checked if the present SPP information indicates that SPP is inhibited or an error. When determined as an error, it is judged if the PPE can be changed to the neighboring edge with removing the error. In an affirmative judgment, the error is automatically removed with the PPE being changed to the neighboring edge together with changing the SPP position and an image being rotated by 90°.Type: GrantFiled: June 6, 2006Date of Patent: September 6, 2011Assignee: Kyocera Mita CorporationInventors: Kozo Tao, Hiroki Saito

Patent number: 8011281Abstract: A punching device includes a detecting unit, a punching unit, a moving unit, a storage unit, and a controlling unit. The detecting unit detects a lateral edge position of a recording medium to obtain edge position data. When the edge position data does not indicate an error value, the edge position data is stored in the storage unit as reference data. The controlling unit determines, when the edge position data indicates an error value, a movement amount of the punching unit based on reference data previously obtained and stored in the storage unit. The moving unit moves the punching unit by the movement amount in a direction perpendicular to the conveying direction of the recording medium.Type: GrantFiled: March 12, 2008Date of Patent: September 6, 2011Assignee: Ricoh Company, LimitedInventors: Makoto Hidaka, Akira Kunieda, Junichi Tokita, Hitoshi Hattori, Ichiro Ichihashi, Kazuhiro Kobayashi, Masahiro Tamura, Tomoichi Nomura, Hiroshi Maeda, Nobuyoshi Suzuki, Tomohiro Furuhashi, Shuuya Nagasako, Naohiro Kikkawa
