Abstract
Abstract Automatic control for tape players using a continuous tape cartridge having a tape-actuated solenoid to trip a release lever allowing a pinch roller to pass between the tape-driving capstan and a spring-loaded pivotal lever-pawl, movement of the pawl rotates a step wheel from which is mounted the pickup head for vertical and parallel movement to the next track on the tape, or if the preselected number of tracks of the tape is completed a latch drops into alignment with the pawl and the cartridge is ejected, automatically shutting off the unit. A manual selector rotates the step wheel to position the pickup head at any desired track through sequential stepping and the circuit is arranged for repeat play, automatic play or play of a selected track set by a manual selector.
