Patent number: 7549621Abstract: A sheet post-processing apparatus is constructed to apply post-processing to sheets successively supplied from an image forming apparatus and received into an apparatus main body, and includes a main discharge tray onto which the sheets that have passed through the apparatus main body are discharged. The sheet post-processing apparatus further has an elevating mechanism for moving the main discharge tray up and down and a control unit for controlling an elevation control of the elevating mechanism. The control unit controls the elevating mechanism to move the main discharge tray up and down in synchronism with the discharge of the sheet onto the main discharge tray. The control unit carries out the elevation control of the main discharge tray so as not to adversely affect the discharge of a succeeding sheet even if the sheet discharged from the apparatus main body is curled up or down.Type: GrantFiled: January 4, 2006Date of Patent: June 23, 2009Assignee: Kyocera Mita CorporationInventor: Takashi Kotani

Patent number: 7520499Abstract: A waiting tray is provided in a sheet-conveying path and holds sheets if the sheets need to be post-processed. A processing tray receives sheets conveyed from the waiting tray. It may receive sheets conveyed through the sheet-conveying path and coming not via the waiting tray, before the sheets are post-processed. A conveying mechanism is provided, which causes the sheets to fall, due to gravity, from the waiting tray onto a processing tray. A sheet-aligning mechanism aligns the sheets on the processing tray, at their transverse edges and longitudinal edges. On the processing tray, the sheets are post-processed, forming a bundle. The conveying mechanism conveys the bundle of sheets to a storage tray. An opening is provided between the waiting tray and the processing tray and located at downstream of the waiting tray and processing tray.Type: GrantFiled: December 10, 2004Date of Patent: April 21, 2009Assignee: Toshiba Tec Kabushiki KaishaInventors: Yasunobu Terao, Reiji Murakami, Tokihiko Ise, Hajime Yamamoto, Hiroyuki Taki

Patent number: 7510178Abstract: A sheet-handling device comprising an intermediate conveyer passage, an intermediate tray, introduction rollers, conveying rollers and a controller. The controller rotates the introduction rollers and the conveying rollers forward and reverse so as to convey two pieces of sheets successively introduced into the intermediate conveyer passage until their trailing ends separate away from the introduction rollers. The conveying rollers are halted in a state where the leading ends are nipped. After the leading ends of the two pieces of sheets have been nipped in an overlapped manner by the conveying rollers, the conveying rollers are rotated forward to convey the two pieces of overlapped sheets into the intermediate tray.Type: GrantFiled: March 22, 2006Date of Patent: March 31, 2009Assignee: Kyocera Mita CorporationInventors: Masahiko Miyazaki, Masuo Kawamoto, Mitsutoshi Takemoto, Takeshi Matsuo, Tetsuya Taguchi, Keisuke Egawa

Patent number: 7494116Abstract: Above a processing tray, a standby tray for making sheets of paper P stand by is installed. The sheets of paper P on the standby tray are dropped, fed, and moved to the processing tray, thus the conveying path from the standby tray to the processing tray is shortened. Furthermore, a Z-folding mechanism is arranged above the standby tray, and the sheets of paper P folded in a Z shape are dropped, and are mixed and stapled on the standby tray or processing tray, and even when performing a plurality of post processes for sheets, miniaturization of a sheet post-process system is retained.Type: GrantFiled: October 22, 2007Date of Patent: February 24, 2009Assignee: Toshiba Tec Kabushiki KaishaInventors: Yasunobu Terao, Yoshiaki Sugizaki, Mikio Yamamoto, Tomomi Iijima, Hiroyuki Taki
