Abstract
A scanning system driving device capable of quickly and gently starting a scanning system. This driving device includes an electromagnetic clutch for forward rotation, for transmitting a driving force from a driving source to a moving body for an optical system, and a control circuit for controlling the application of a voltage to the electromagnetic clutch. The control circuit applies a rated voltage in the form of pulses to the electromagnetic clutch at intervals of such OFF time that the moving speed of the moving body is reduced once when the illumination and the scanning of a document by the moving body are started.
