Abstract
An image of original is projected on an image reading element such as CCD selectively at a first magnification or at a second magnification. The first optical system for projecting the original image at the first magnification and the second optical system for projecting the original at the second magnification are separate systems and both of the optical systems are fixed. The magnification at which the original image is projected on the image reading element is changed from one to another by closing the optical path of the first optical system or that of the second optical system.
