とする光学系の倍率切換機構。In an optical system that forms an image of a read document onto a photosensor using a fixed lens, a mirror is inserted between the read document and the lens to detour the optical path, and a glass plate is inserted between the lens and the photosensor. An optical system characterized by making it possible to form images of the same read document at different magnifications on the same 7-photo sensor using the same lens by shortening the apparent optical path length. Magnification switching mechanism.
