Abstract: Optical system includes front group, light-shielding member, and rear group that are arranged in this order in direction from object side toward image side. The light-shielding member is provided with opening elongated in first direction. The front group has aspherical surfaces, does not image the object at the opening in first section parallel to the first direction, and forms intermediate image of the object at the opening in second section perpendicular to the first direction. The rear group has diffractive surface that splits light beam that passes through the opening into light beams at different wavelengths in the second section and focuses the light beams on different locations in the second section. Tilt angles of the aspherical surfaces in the second section change in the first direction.

Abstract: In the invention, for a first sheet, regardless of the sheet size (width), a lateral registration detector is moved in a direction towards an edge face of the sheet from a home position to detect the edge face of the sheet. With lateral deviation in the sheet position corrected, punching is performed by a puncher. For the second and subsequent sheets, the lateral registration detector is moved in advance to near the edge face of the sheet with reference to the detected position of the sheet edge of the first sheet, and the edge face is detected at a given timing. With lateral deviation in the sheet position corrected, punching is performed by the puncher.
