Abstract

PURPOSE: To correctly locate a stylus at intra-music, by driving a pickup arm based on an output operating each output of two intra-music detectors located near the stylus tip and an output operating a specified reference voltage.
CONSTITUTION: Intra-music sensors 1 and 2 provided at the tip of a pickup arm 3 are constituted with two photo detectors 6a and 6b arranged along the rotating direction of the arm. The photo detectos 6a, 6b generate outputs as 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 operation processing circuit 7 to control the lift-down position of the stylus tip 4, and the direction of rotation and speed of the arm is controlled with the output of a position/speed reference voltage generating section 11 and an arm speed detection section 12 via the horizontal drive section 10 at lead-in or return. The drive timing of the horizontal drive control circuit 9 is made by the control signal from a system controller 13.
