Abstract
A ribbon cassette incorporates a locking mechanism which acts to prevent both rotational spool movement and axial displacement or 'treeing' of the coils of ribbon wound on a single flange supply spool prior to mounting for use in a typewriter. The locking mechanism is automatically released when the cassette is mounted for use in a typewriter or like machine.
