Abstract

PURPOSE:To obtain a normal copied picture all the time by equipping one photoreceptor with original tables and optical systems and by exposing a photoreceptor by one optical system without fail. CONSTITUTION:The 1st optical system 8 and 2nd optical system 9 are constituted by using exactly the same members and arranged symmetrically on a photoreceptor 6. With the 1st and 2nd copy buttons 4 and 5 made ON, the optical systems 8 and 9 operate respectively to turn on lamps 19a and 19b and also to scan originals on original tables 2 and 3 in a slit shape. Then, an original is mounted on, for example, only the 1st original table 2 and the 1st copy button 4 is pushed, so that while only the lamp 19a of the 1st optical system 8 turns on, the lamp 19b of the 2nd optical system never turns on. Consequently, interrupting copying operation is facilitated to improve processing effect, and a picture is prevented from becoming unsharp.
