Abstract

PURPOSE: To achieve the elimination of tracking errors by providing a control mechanism which so controls and arm that it always positions on a reference line by controlling the movement quantity of a moving base.
CONSTITUTION: The rotating shaft 5 of a tone arm 4 is directly mounted rotatably to a base 1 and on the other hand a motor 3 which drives a turntable 2 is mounted to a moving base 11. Here, these are so constituted that the arm 4 is directly supported to the base 1 of high rigidity and the moving base 11 mounted with the turntable 2 having large mass and a motor 3 moves. As a result, the propagation level of the vibrations generated from the moving mechanism reduces because the mass and rigidity of the moving objects are high, thus the S/N of the reproduction signal may be made higher as compared to that of ordinary apparatus wherein the arm 4 is moved.
