Abstract

PURPOSE: To make the assembling easy with simple constitution, by providing the magnetism sensing element opposing to the boundary part of the magnetization of magnet of the motor controlling the swing movement of the tone arm and detecting the deviation angle of the tone arm toward the tangential direction of record disc.
CONSTITUTION: The tone arm is supported with the carriage, and linear tracking is made with the tone arm through the linear movement of the carriage, and the motor is provided to the swing shaft of the tone arm concentrically and the swing movement of the tone arm is made for motional feedback control. In such a constitution, the magnetism sensing element 73 which detects the deviation angle of the tone arm by opposing to the boundary part of magnetization of the magnet 62 constituting the stator of the motor 60, and if the tone arm is deviated by an angle to the tangential direction of record disc, a signal proportional to this deviation angle is outputted.
