Abstract:
1. A sheet processing apparatus comprising: a first detection unit configured to detect a position of a side edge of a sheet in a width direction perpendicular to a conveying direction of the sheet; a moving unit configured to hold the sheet and move the sheet in the width direction; a motor configured to move said moving unit in the width direction via a driving force transmitting member; a second detection unit configured to detect movement of said moving unit; and a control unit configured to control a drive of said motor based on the position detected by said first detection unit so that the side edge of the sheet moves to a reference position in the width direction, and determine timing with which the driving of said motor should be stopped based on a drive amount of said motor from when said motor start driving until when said second detection unit detects that said moving unit starts driving.
