Abstract

PURPOSE: To enable to adjust a stylus tip falling down reference position, by outputs operating the output of two intra-music detectors located near the stylus tip and of adjustable reference voltage.
CONSTITUTION: Intra-music sensors 1 and 2 provided at the tip of a pickup arm 3 are constituted with two photo detectos 6a and 6b arranged along the direction of rotation of the arm. The photo detectors 6a, 6b produce an output shown in Figs. A (a) and (b) in response to the lead-in or return and apply them to an operation processing circuit 7 and a waveform processing circuit 8. A horizontal drive control circuit 9 controls a horizontal drive section 10 with an output adjusted at the circuit 7 at an intra-music location to control the falling down position of a stylus tip 4, and controls the direction of rotation of the arm and the speed with the output of a position/speed reference voltage generating section 11 and an am speed detection section 12 via the horizontal drive section 10 at the lead-in or return. The drive timing of the circuit 9 is based on a control signal from a system controller 13.
