ABSTRACT:
A scan type anamorphic magnifying apparatus provided with a scanning device for scanning an original document in form of a slit, an image forming device for projecting and forming an image of the scanned document on a photosensitive member, and a device for substantially continuously varying a moving speed of the scanning device relative to a moving speed of the photosensitive member to permit the image of the document to be formed on the photosensitive member in varied magnifications. The apparatus further comprises an anamorphic optical unit movable into and out of a projection optical path leading to the photosensitive member. This optical unit is moved out of the optical path when anamorphic magnification is in a range close to "1" and into the optical path when the magnification is in a range far from "1".
