を特徴とするリニアトラッキングアーム。A tone arm movement guide, a tone arm fixed base slidably fitted into the movement guide, a tone arm having a rotating shaft on the fixed base and rotatably attached to the fixed base; a needle tip attached to one end, a leaf switch attached to the other end of the tone arm and having a first contact at its free end, and a second leaf switch fixed to the fixed base opposite to the first contact. A contact, a motor that is driven when the first and second contacts are closed, and a power transmission mechanism that moves the fixed base inward of the turntable by rotation of the motor, and the mechanism includes a record groove trace of the stylus tip. A linear tracking arm characterized in that the deviation angle between the direction of the record groove and the direction of the record groove is always small during record playback.
