Abstract
PURPOSE: To secure operation with simple constitution by providing rotor magnets to an elevating cam related to the elevating motion of a tone arm and a rotary disk related to the turning motion.
CONSTITUTION: Rotary disk 23 having elevating cams 26a and 26b related to lift axle 14 for putting tone arm 1 in elevating motion and engagement projections 27a and 27b related to turning plate 16 for putting tone arm 1 in turning motion is provided with rotor magnet 24. Then, the electromagnet driving rotor magnet 24 is provided to frame 20 that supports pivotally rotary disk 23 and between frame 20 and rotary disk 23, damping member 25 is further provided. Electromagnet 21 is applied with voltages differing in polarity to turn rotary disk 23 in the reciprocal directions, so that tone arm 1 moves up and down and turns.
