ABSTRACT:
A control system for a scanning arrangement adapted to be driven for reciprocating movements by a motor, which includes a power source circuit, a circuit for outputting a signal upon turning off of the power source, provided in the power source circuit, a capacitor connected in parallel with the motor, provided at a stage subsequent to the power source off signal output circuit in the power source circuit, and a control section for driving the motor, arranged to control in such a manner as to brake the motor upon output of the power source off signal from the power source off signal output circuit during energization of the motor, so that the scanning arrangement is successfully reduced in speed so as to be stopped, even when the power source is turned off during movement of the scanning arrangement.
