ABSTRACT:
A sheet processing apparatus includes a hole punching section arranged orthogonally to a conveying path of a sheet, a moving mechanism which moves the hole punching section along a direction orthogonal to the conveying path, a detection unit which is arranged upstream from the hole punching section and which moves by being interlocked with the hole punching section and detects a lateral edge of the sheet conveyed thereto, and a control unit which controls the moving mechanism in accordance with the result of detection by the detection unit and varies the position of the hole punching section, thus controlling the punching processing position. The control unit causes the hole punching section to be moved in the direction to the retreat position along with the conveying of the sheet, causes the hole punching section to retreat by a prescribed quantity with reference to the result of detection by the detection unit, then causes the hole punching section to be moved in the opposite direction, and controls movement to the punching processing position in accordance with the result of detection by the detection unit.
