Abstract
PURPOSE: To search for the beginning of an optional program precisely through simple operation by detecting the extent of rotary displacement of a tone arm by a photosensing means, and by sliding and guiding an arm base by a signal based upon the detection.
CONSTITUTION: An arm base 6 which has a photosensing means 11, a means of sliding and guiding the arm base in the moving direction of a tone arm 12, and an arm holder 10 which is so provided to the arm base 6 that it is rotatable in parallel to the surface of a record disk 3 and has a light shielding plate 102 are provided. Then, the rotary displacement of the arm holder 10 is detected by detecting the light shielding plate 102 shielding the photosensing means 11 from light, and the detection signal is stored in a memory circuit and processed by an arithmetic circuit together with the output of an address specification input circuit, thus controlling a motor 7 for driving the arm base by the output of the arithmetic circuit.
