Abstract

PURPOSE:To reduce the heat generation of a power source circuit by reducing its capacity by exercising control so as to prevent two driving motors for a turntable and a tone arm when driven from being both in high-pewer-consumption states at the same time. CONSTITUTION:In operating a full-automatic player, etc., having two driving motors, one motor for driving a tone arm is not actuated until the other motor for driving a turntable is actuated and reaches a prescribed rotational frequency and then this motor changes from a high-power-consumption state to a low-power-consumption state. Then, the tone-arm driving motor is in the high-power-consumption state before the tip of a srylus fitted atop of the tone arm reaches a prescribed position on a record surface and before the tone arm after play returns an arm rest, so the stopping of the turntable requiring high power consumption is not done. Thus, the operation states of both the motors are controlled by using a microcomputer so as not to attain both the driving motors to the high-power-consumption states, thereby reducing the capacity of a power source and the heat generation of a power source circuit.
