Abstract

Abstract The invention relates to automatic record changers adapted particularly for reproducing records of different diameters. The records may be held in intermingled stacked relationship upon a supporting spindle element prior to release for play. A series of cams carried and supported for rotation upon a single camshaft functioning with suitable controls determines the operational sequence control. Rotation of the camshaft and its cams over a preestablished angle (usually 360*) controls the operation. Camshaft rotation is interrupted each time the shaft turns through the selected angle and is then reinitiated either manually or automatically. All normal operations are established in known sequence.
