PURPOSE:To change switching positions easily for the scanning exposure of an original by allowing a position specifying switch to slide optionally and freely on switching positions of an optical system for the 1st and the 2nd originals. CONSTITUTION:A platen 2 is provided with a scale 43 which indicates copying lengths corresponding to originals of various sizes, and a carriage 47 is provided with a scale 44. Then, read switches 122 and 123 are provided near the movement position of a moving body 12 provided to a belt 52. The reed switch 123 is turned on when the optical system on the carriage 45 corresponds to the switching positions of the 1st and the 2nd originals. The reed switch 123 is movable on a rail 124 as shown by an arrow C and moved by a slide switch connected through a plate body 125. |
