Abstract

PURPOSE: To obtain the unit with high reliability and simple construction, by generating the output in response to the difference between the position signal and reference signal after comparison, and correcting the amount of light of light emitting element in response to the output.
CONSTITUTION: The unit provides the first position detection means 10 generating the shift position of the tone arm 1 by means of the light emitting element 11 and photo detectors 13a, 13b, second position detection means detecting the specified position of the tone arm 1, reference signal generating means 18, 24 generating the reference signal in response to the specified position, comparison means 14, 17, 22 generating the output in response to the difference between the position signal and reference signal at the output generation of the second position detection means 23 after comparison, amount of light correction means 22 correcting the amount of light of the light emitting element 11 in response to the output of comparison means.
