Abstract

PURPOSE:To simplify the mechanism, by driving first and second pulse motors to move first and second reflecting members and changing the initial rotation position of the second pulse motor in accordance with an objective exposure magnification. CONSTITUTION:In the such down copy mode, when an input device 37 is operated to designate this mode, a signal from the device 37 is inputted to a CPU35, and the CPU35 detects it to select data corresponding to this mode out of data stored in an ROM30 and drives pulse motors 28 and 29 through an output port 33. Similarly to the real size copy mode, initial positions of pulse motors 28 and 29 are positioned to position an optical system, namely, moving mirrors 4 and 5, and they start movement from these positions to perform the reduction copy.
