Patent ID: 7665730

Claim:
A sheet processing apparatus comprising: a cross-directionally moving device, which is brought from a standby position into pressure contact with an upper surface of a sheet to move the sheet in a direction crossing a sheet discharging direction; a cross-side restricting member, which receives one side edge of the sheet moved in the crossing direction by said cross-directionally moving device, and restricts a movement of the sheet, said one side edge of the sheet being along the sheet discharging direction; and a controller, which changes said standby position of said cross-directionally moving device in the crossing direction in accordance with a sheet width of the sheet in the crossing direction, wherein said cross-directionally moving device is brought from said standby position into pressure contact with an upper surface of a next sheet at a position between the other side edge of the sheet received by said cross-side restricting member and said cross-side restricting member to move from said position in the crossing direction to move the next sheet to said cross-side restricting member.
