Abstract
A cam unit includes three cams fixed on a common cam shaft for moving a pair of feeding rollers, a pair of lateral registration rollers, and a stopper unit, respectively. A control unit corrects a lateral registration of a sheet whose skew is corrected by the stopper unit, based on a detection result of a detecting unit that detects a position of a side edge of the sheet, while conveying the sheet, controls the rollers not nip the sheet at least during the lateral registration, and controls rotations of the cams according to a length of the sheet.
