Patent ID: 8118303

Claim:
A sheet conveying apparatus, comprising: a shift unit which conveys a sheet, and which is capable of moving in a width direction perpendicular to a sheet conveying direction while the shift unit conveys the sheet; a drive mechanism which moves the shift unit in the width direction; a detecting portion which is moveable in the width direction and which detects a side edge position of the sheet to be conveyed to the shift unit; and a control device which controls the drive mechanism to move the shift unit in the width direction, wherein the control device obtains a displacement in the width direction of the sheet to be conveyed to the shift unit based on a detecting result of the detecting portion, and controls the drive mechanism so as to move the shift unit in the width direction by a moving amount calculated from a predetermined shift amount in the width direction with respect to a central position of the sheet processing apparatus for sorting each sheet group and a correcting amount for correcting the displacement in the width direction.
