• a generally cylindrical hub engaing member movably mounted on said first side wall for movement between extended and retracted positions with respect to said first side wall;
• said hub engaging member being located and dimensioned to be received in the recess of said hub reel when the cassette is placed in said container and having a top wall adapted to engage said bottom wall of the reel hub;
• said top wall including at least one button extending therefrom for engagement in one of the door holes on said reel hub bottom wall, and spring means positioned within said hub engaging member and operatively engaged between said first flat wall of the container and the top wall of said hub engaging member to bias said hub engaging member towards its extended position thereby to urge said hub engaging member into the reel hub recess to engage said button in one of said drive holes when there is alignment therebetween;
