Abstract

PURPOSE: To obtain an inexpensive and simple tone arm driver by fitting a body of revolution with a lift cam on a center shaft provided to a frame and then by providing the frame with the 1st electromagnet that controls the rotation of the body of revolution and the 2nd electromagnet that drives the 1st electromagnet and a turning arm.
CONSTITUTION: Vertical turning shaft 7 of tone arm 1 is supported by turning arm 13 and lift shaft 12 lifting and lowering tone arm 1 is brought into contact with the bevel of lift cam 23 provided to revolving body 21 supported by turning shaft 17. Frame 16 is provided with permanent magnet 20 and the 1st and 2nd electromagnets 27 and 28 and the revolving body 21 is provided with brake plate 26. When electromagnets 27 and 28 are fed with electric current through switches coupling with permanent magnet 20 and the 1st electromagnet 27, tone arm 1 is lifted through the rotation of frame 16 and the revolving body 21 and led to the play start position through the rotation of turning arm 13 and then the electromagnet 28 is released via the switch to lower the tone arm through electromagnet 27, thereby finishing the lead-in operation. Consequently, the unit can be made simple and inexpensive.
