Abstract
PURPOSE: To render tha intensity of illumination on the image surface to be nearly uniform by shifting an illuminating means to the shifting direction of an optical axis of the lens by the same amount as the amount of shifting of the optical axis of the lens in accordance with a required vairable magnification in order to corren the intensity of illumination of a document together with the aperture efficiency of the lens.
