Abstract

Abstract Record-driving motor is swingably mounted and the motor output shaft is spring-loaded against a record thereby trapping a phonograph needle between record groove and fixed speaker cone. Needle pressure is relieved at end of play so that spring-loaded output shaft siwngs sufficiently to move motor into a deenergized position. A reset button tips motor sufficiently to lower one side of record away from neelde permitting it to return to the outer edge of record.
