Abstract
PURPOSE:To make a copying machine usable as it is even in areas of different frequencies by identifying the AC power source frequency which changes the number of revolutions of a copying machine drive motor and generating a predetermined control signal. CONSTITUTION:When the AC power from an AC power source AC is supplied via a relay SSR, the number of revolutions of a motor IM changes according to the AC frequencies. This AC power is simultaneously supplied to a power source frequency identifying signal generating circuit IS via a transformer T. Then, the AC current is half-wave rectified by the diode 22, resistance 21, etc. of the circuit IS, after which it is applied to a comparator 23 connected with resistances 24-26 of predetermined resistance values, resistances 27, 28 for feedback and a diode 29, whereby the AC power source frequency is identified. The pulses of the width of the period of a positive level corresponding to the AC frequency are generated from the comparator 23 and are applied to a control part C. As a result, the control part C generates timing pulses for required controlling corresponding to the revolutions of the motor IM changing according to the AC power source frequency, thus the copying machine which is usable in areas of different AC frequencies with the same constitution is obtained.
