ABSTRACT:
A videotape cassette has a visor-type door, at each end of which is an ear or corner part at which a pin hinges the door to a housing. As in the prior art, the door is biased to either a fully opened or fully closed position. In the novel cassette, the biasing results from a free-standing finger formed in a wall of the housing, which finger acts as a spring against a squarish platform on the inner face of an ear of the door.
