Abstract

PURPOSE: To ensure compensation of the velocity fluctuation for the arm rest by installing the horizontal driving coil to the rest of the linear tracking arm and then supplying the control current to the horizontal driving coil based on the shift velocity of the arm rest.
CONSTITUTION: Horizontal driving coil 28 is attached to carriage 27 via pole 29, and field component 30 is fixed to the frame of the player. When the driving current is supplied to driving coil 28, carriage 27 is shifted horizontally. This driving current is based on the detection signal of horizontal revolution detector 39. When the angle of tone arm 1 varies through tracing of the record grooves, the output of electromagnetic conversion element 41 varies by detector 39. Thus the driving current is supplied to coil 28 to turn the variation amount of the output of element 41 to zero. As a result, a smooth shift is secured for carriage 27, thus avoiding the noise occurrence to the reproduced sound.
