とを特徴とする複写機の倍率変換装置。 In a copying machine in which the copying magnification is changed by moving the lens carriage 5 using a pulse motor 9, this is caused by hysteresis in the lens carriage moving device when the lens carriage 5 moves in the opposite direction to the previous movement direction. A magnification conversion for a copying machine characterized by having a hysteresis pulse number calculation means for calculating the number of pulses of the pulse motor 9 corresponding to the insufficient travel distance and inputting the corrected number of pulses at this time to the pulse motor 9. Device.
