PURPOSE:To obtain a copied image having good quality with a simple construction by driving pulse motors by the pulse signals of prescribed frequencies and moving a scanning system at the prescribed speed corresponding to magnifications. CONSTITUTION:The pulse signal of a specified frequency from a generation circuit 50 for a reference signal is divided down to prescribed frequencies by frequency division circuits 51,52,and said signals are fed to pulse motor driving circuis 53, 54, by the outputs thereof, pulse motors M1, M2 for moving an object are driven at the prescribed speeds according to a copying magnification. The copied image having good quality is thus obtd. with the simple construction. |
