Abstract
PURPOSE: To simplify the circuit of the muting device by opening or closing the magnetic sensitive switch provided in the pick up arm by means of a magnet mounted on the lifter device.
CONSTITUTION: Two lead switches 4 a, 4b are dispoed in a hollow portion of the pick up arm 1 and the lift arm of the arm lifter device 5 is formed by a permanent magnet. In response to the upward and downward movement of the device 5, while the lift arm 6 abuts against the arm 1, the switches 4a, 4b are closed to short circuit the cartridge 2. Oppositely, when the spacing between the lift arm and the arm 1 is opened, the switch is opened and the short circuited cartridge is released. Namely, there is no generation of uncomfortable noise in the case of the cartridge abutting against the record disc or disengaging thereform. In this manner, the special magnetic shield and switch operating power source is necessary and the circuit can be simplified.
