Abstract
PURPOSE: To avoid the inconvenience such as leakage of liquid, by the constitution that the braking force for the follower is operated to the lift shaft in a viscoelastic liquid.
CONSTITUTION: The lift shaft 10 is lifted up by applying the power supply of unipolar to the coil 15 forming an electromagnet 11 and the lift arm 9 coupled with the lift shaft 10 can lift up the tone arm 1. On the other hand, by applying the power supply of different polarity at lifting up, the lift shaft 10 is fallen down the tone arm 1 can be made down with the lift arm 9 coupled with the lift shaft 10. Further, at the lifting up and down of the tone arm 1, that is, at lifting up and down of the lift shaft 10, the follower 16 receives the resistance of the viscoelastic liquid 18 in the sealed case 17, allowing a suitable braking force to the lift shaft 10 and to lift up and down the tone arm 1 smoothly.
