ABSTRACT:
There is disclosed a tonearm linear-drive apparatus wherein the pivotal point of the tonearm is moved in the linear direction which is parallel with the pickup stylus linearly moving direction across the record disc being played, by using at least a portion of gravity force. A sliding mechanism having the tonearm supported at the pivot point is provided adapted to slide along a linear track by the portion of gravity force in the same direction as that of the linear movement of the pivotal point of the tonearm. A braking mechanism is provided responsive to the above stylus movement and the above pivotal point movement for starting and stopping the above sliding mechanism movement.
