Abstract
PURPOSE: To simplify the constitution and to reduce the price of product, by giving both the horizontal and vertical operations to the tone arm by one motor.
CONSTITUTION: The magnet mechanism is constituted with the exciting coil 4 fitted to the rotor yoke plate 5 and the magnet 6 of the stator yoke plate 7. The tilt plate cam 13 and the arm lifter shaft 15 form the arm lifter mechanism. To lift up the stylus tip from the record playing state shown in Figure, when the electromagnet 11 is turned on and power is applied to the coil 4, the yoke plate 7 turns counterclokwise and the stylus is lifted up vertically via the shaft 15. With this state, when the electromagnet 11 is turned off, the yoke plate 5 turns clockwise and the arm turns in rest position. After that, the power to the coil 4 is disconnected. The playing state from the rest position is made by the reverse operation as the said operation.
