Image reader

Abstract

Abstract PURPOSE:To increase the range of variable magnification greatly by retracting a 1st reflecting optical member from a 1st optical path, advancing an optical translucent document in a plane intersecting orthogonally with the traveling direction of the light in the 1st optical path, and making transmitted light incident on a 2nd reflecting optical member. CONSTITUTION:When an image forming lens L is set at a specific position in the 1st optical path to constitute an enlargement optical system, an image is read by moving a translucent recording medium OL which is already recorded for subscanning without moving the optical system. A reflecting mirror M1 is moved out of the optical path of the light from the light source LS so as to use the light source LS to be served also as a light source for lighting the translucent recording medium OL which is already recorded, and the translucent recording medium OL which is already recorded is moved into the passage of the light from the light source LS for subscanning to read the image.
