Abstract

PURPOSE: To erase discordant noise, by attenuating or inhibiting the reproduced output for a fixed time including the time when the record stylus is brought into contact with the record.
CONSTITUTION: A vertical movement detecting means for tone arm 1 which consists of light emission device 6a and photo detecting device 6b in the left and the right is provided with tone arm 1 as the center. Slit plate 8 which shields irradiated light L is provided in the lower side of tone arm 1 which is opposite to this detecting means 6a and 6b, and attenuating device 7 is operated instantaneously by the output of photo detecting device 6b to attenuate the reproduced output signal. As a result, noise caused when the record stylus and the record are brought into contact with each other can be attenuated, so that discordant noise is not generated.
