Cassette having at least one axially movable reel and having blocking means for blocking an axial movement of the reel

摘要

A cassette having a reel which is movable axially away from the cassette bottom wall to a drive position against the force of a spring. When in a rest position the reel is locked against rotation by a latching device which is arranged completely inside the cassette. A blocking device adjacent the reel hub prevents movement of the reel axially. Upon movement of a reel drive device into the cassette, the blocking device is moved to a release position so that the reel can be moved axially to a drive position in which the latch device is inoperative.
