Abstract

PURPOSE: To keep the arm steady when the power supply is interrupted and thus ensure a smooth manual operation, by giving the horizontal balance control to the tone arm in the state under which the prescribed bias current is applied to the linear motor for the vertical driving purpose which moves up and down the tone arm.
CONSTITUTION: The following units are provided: vertical drive motor 3 which moves up and down tone arm 1; horizontal balance control means 10 for the arm; means 11 which supplies stylus pressure setting current IP to motor 3; means 17 which supplies bias current IB to motor 3 to make motor 3 generate a certain amount of force by which arm 1 is moved up; and switch 14 which cuts off the application of the stylus pressure for the balance control of arm 1. Then the horizontal balance control is given to the arm in the state under which the prescribed bias current is applied to motor 3. And the downward force is applied to arm 1 when the power supply is interrupted. As a result, arm 1 can always be kept steady.
