  • Publication number: 20110024973
    Abstract: In a sheet processing apparatus, a pair of regulating members is provided at a pair of joggers so that the regulating members are movable together with the joggers. When the pair of joggers is laterally moved, the pair of regulating members also laterally moves together with the pair of joggers. By moving the pair of joggers to passage positions, the pair of regulating members regulates the lateral ends of a sheet, which falls and is stacked on a first stacking tray.

  • Publication number: 20100171256
    Abstract: The present invention provides a sheet processing apparatus that can prevent, with higher certainty, lift of the trailing end of each sheet placed in sheet stacking portion. This apparatus includes a first holding member and a second holding member that prevent lift of the trailing end of each sheet from an intermediate stacking portion. When introduced to the intermediate stacking portion, the subsequent sheet comes into contact with the first holding member, so that the first holding member moves to the retracting position. As the subsequent sheet continues to be conveyed, the subsequent sheet comes into contact with the second holding member, so that the second holding member moves from the restricting position to the retracting position. As the trailing end of the sheet is introduced, the first holding member moves from the retracting position to the restricting position, to hold down the trailing end of the sheet.

  • Patent number: 7607659
    Abstract: A sheet conveyed to a sheet stacking portion is conveyed in a direction opposite to a sheet conveyance direction by a returning roller to bring a trailing edge of the sheet into abutment against a reference wall and regulate a trailing edge position of the sheet. A pressure portion which presses the sheet to the reference wall is pivotably provided between the returning roller and the reference wall. The pressure portion presses the sheet conveyed by the returning roller to the reference wall while urging the sheet with a first urging force and, after the sheet comes into abutment against the reference wall, is urged by the urging unit to press the sheet, the trailing edge position of which is regulated by the reference wall, with a second urging force larger than the first urging force to hold the sheet.
