SO1517 RECORD PLAYER PROGRAM SELECTOR ABSTRACT OF THE DISCLOSURE A program selector for a record player of the type having a turntable supported on a movable carrier which is actuable to move the turntable into and out of a housing, and having a tone arm which is movable across the surface of a record and controllable to play back at least a selected one of plural programs recorded on the record in separate segments which are spaced apart from each other by respective inter-program gaps. An inter-program gap detector detects the location of each inter-program gap on the record and produces an inter-program gap signal representing that location as the carrier moves the turn- table into the housing. A selector is provided for selecting a program to be played back by selecting a particular inter-program gap signal which represents the location on the record of the desired program. A tone arm position detector detects the position of the tone arm as it moves across the surface of the record and produces a tone arm position signal representing the relative position of that tone arm. A control circuit compares the tone arm position signal to the selected inter-program gap signal and produces a control signal when the tone arm position signal corresponds to the selected inter-program gap signal so as to cause the tone arm to play back the selected program. -i-
