Patent number: 9329555Abstract: There are provided a sheet processing apparatus which can perform a punching process while suppressing decrease in productivity, and an image forming apparatus including the sheet processing apparatus. In a third carry-in route R3 branching from a first carry-in route, a discharge roller and a buffer roller convey a sheet for which the punching process has been performed by a punching unit, so that an upstream end in a sheet conveyance direction of the sheet for which the punching process has been performed precedes an upstream end in the sheet conveyance direction of a succeeding sheet following the sheet for which the punching process has been performed.Type: GrantFiled: September 28, 2010Date of Patent: May 3, 2016Assignee: Canon Finetech Inc.Inventors: Norio Motoi, Kenji Toppada, Hiroki Hommochi, Yoshihiko Kitahara

Patent number: 8186677Abstract: In order to stack a larger number of sheets on trays by reducing a total thickness of the trays and enabling the trays to ascend and descend actually over long distances, a sheet stacking device includes an upper-tray and a lower-tray which are ascendible and descendible and on which sheets delivered from a delivery roller pair are stacked, a motor and a belt for allowing both the trays to ascend and descend, a clutch for disconnecting the upper-tray and the belt from each other, and a claw and a rack for stopping self-weight descent of the upper-tray when the clutch effects the disconnection. A clearance between the upper-tray under the disconnection by the clutch and in the stop of the self-weight descent by the claw engaged with the rack and the lower-tray connected to the belt is adjustable by ascent and descent of the lower-tray by the motor.Type: GrantFiled: September 28, 2010Date of Patent: May 29, 2012Assignee: Canon Finetech Inc.Inventors: Norio Motoi, Kenji Toppada, Hiroki Hommochi, Yoshihiko Kitahara

Patent number: 6276677Abstract: In a sheet bundle folding apparatus for folding a bundle of sheets in two, a stick-out plate for sticking the bundle of sheets is adapted to reliably stick the bundle of sheets folded while being held between rollers for folding the bundle of sheets in a folding position therefor. A first folding roller is positionally fixed. A second folding roller is movable toward and away from the first folding roller. The stick-out plate sticks the bundle of sheets and pushes it into between the first and second folding rollers. At this time, the rollers of the stick-out plate roll along a groove. The forward roller is fitted in the groove with a correction allowance above it, and is downwardly biased by a spring. The stick-out plate follows the folding position for the bundle of sheets.Type: GrantFiled: December 18, 1998Date of Patent: August 21, 2001Assignee: Canon Kabushiki KaishaInventors: Hiroki Hommochi, Seiichiro Adachi
