Abstract: There is provided a position detecting device using reflection type photosensors in which a position sensing of lens located not less than 1 mm apart from a sensor can be conducted. A pair of reflection type photosensors PR1 and PR2 are oppositely arranged, a double sided reflector 5 attached on a movable body is movably arranged between the pair of reflection type photosensors and a position of the double sided reflector 5 is detected from the outputs of these reflection type photosensors. In the position detecting device of the present invention, an operating formula in which linear values are obtained depending on a moving distance of the double sided reflector can be used. For example, when an output of one of the pair of reflection type photosensors is Vo1, and an output of the other is Vo2, the position detecting is conducted using the operating formula of (Vo1?Vo2)/(Vo1+Vo2).

Abstract: A pickup arm is equipped with a photo sensor assembly for detecting non-recorded portions on a disk. The sensor is located in such a position that horizontal distance between the stylus tip and the detecting point of the sensor measured in the direction of the radius of the turntable is substantially constant throughout the possible rotational angle of the arm. The rotational angle of the arm is measured and is modified by a given angle corresponding to the above mentioned distance. When this distance deviates from a standard value on replacement of the same with another, the variation may be readily corrected by manipulating a potentiometer. Prior to performing an automatic playback, the disk is scanned by the sensor and signals indicative of the arm angles corresponding to the non-recorded portions are stored.

The address signal generating device supplies the generated address signal to the control device. The control device reads out the magnitude of the inside force from the memory device corresponding to the supplied address signal, produces a signal for cancelling the inside force at the rotational angle position of the tone arm corresponding to the read out magnitude of the inside force and supplies the same to the horizontal drive motor.
