Abstract

PURPOSE: To perform compensation of inside force by providing a detecting means of detecting the turning position of a tone arm and an operating means calculating the outside force for negating inside force with the signal thereof.
CONSTITUTION: A slit plate 22 and a position detector 8 consisting of a light emitting element 23 and a photo detector 24 are provided to the arm shaft 2 of a tone arm 1, and the pulses corresponding to the turning angles of the tone arm 1 are obtained from the photo detector 24. The pulses are applied together with the output from a stylus pressure adjusting circuit 27 to a microcomputer 32, by which operations are accomplished and the output thereof is applied to the horizontally controlling coil 10 of the tone arm 1 via D/A converter 34. Since this enables the inside force according to the stylus pressure and the turning angles of the tone arm 1 to be negated with an electromagnetic means, operation may be made stabler and surer compensation quantity may be obtained as compared to the ones of mechanical constitution.
