This invention for reading an image of a document employs a optical projection magnification lens for projecting the image of a document; a movable image reading device for transforming the projected image into electrical signals and for providing a focussing adjustment; an electrical magnification process for varying electrically the size of the image projected on the image reading device; and a controller for controlling the optical projection lens, the electrical magnification process, and the movable reading device.
