Movement of each sensor toward an end of the pipe causes a pulse generator to produce pulses that decrement from a preset value indicative of the distance between two axially disposed reference points.

Abstract: Apparatus for controlling an arm of a record player of the type having a base, a turntable upon which a record disc rotates, a pivot support extending upward from the base for supporting the arm and about which pivot support said arm pivots in a plane perpendicular to the surface of the record disc, and a transducer at one end of the arm for scanning the record disc. Pivotal movement of the arm is detected and a position signal is produced to represent the angular position of the arm. A detecting circuit detects when the position signal differs from a predetermined reference signal, this difference corresponding to an angular displacement of the arm, to produce a control signal. A drive device is coupled to the pivot support and is responsive to the control signal for driving the pivot support in a direction perpendicular to the surface of the record disc so as to reduce the angular displacement of the arm and thereby adjust the position signal until it is equal to the predetermined reference level.
