This invention is an electronic circuit which controls the rotating motor, it turns the direction, and the driving motor, it controls a covering and a stop, according to a given input program of an unmanned conveyance car. The triangular wave and the velocity control signal of a control circuit will input to the OP3 of a comparator, and the output of a comparator will generate a square wave pulse signal when the CTL1 exists between maximum and minimum level of a triangular wave. Hence, the driving circuit of a driving motor and the driving control part and the driving motor are connected to an output port of a comparator.
