Abstract
A spool mounting apparatus, particularly suitable for automatic, unbuffered tape transport systems, permits a reduction in the handling of spools during loading sequences. A spool inserted through an opening into a cavity within a housing, is guided into a preliminary position by a detent pin. The opening possesses a spring biassed closure member, which is mechanically linked to a free running disc member within the cavity situated opposite a shaped cylindrical hub over which the spool may locate. Motion of the spring biassed closure member towards a closed position effects displacement of the free running disc member towards the hub, thereby clamping the spool disposed therebetween. Subsequent rotation applied to the hub is therefore transferred to the clamped spool and the free running member.
