ABSTRACT:
A static tape cassette reel lock is described. In one embodiment a tape reel flange has on the outer circumference thereof a plurality of teeth, and the cassette base includes a plurality of slanted vertical ribs and a centered slanted horizontal rib. The teeth of the flange are able to move past the angled ribs so that the tape reel can rotate in one direction, but does not allow rotation in the other direction. In another embodiment the reel hub includes a chamfered ring of teeth. The cassette base includes a corresponding ratchet ring of ramped teeth. Again, rotation in one direction is allowed, but not in the opposite direction.
