In a storage receptacle for a magnetic tape cassette comprising a housing having spaced apart, parallel side walls which, between their forward edges, define an opening of the housing, and a holder pivotally connected with the housing for swinging movement through such opening between an opened position in which the holder projects forwardly from the housing for receiving and relinquishing a cassette, and a closed position in which the holder cooperates with the housing for enclosing a cassette in the receptacle; the pivotal connection of the holder with the housing provides a fulcrum for the holder which is spaced rearwardly from the center of gravity of the holder with a cassette therein in all positions of the holder ranging from its closed position to its opened position so that the force of gravity urges the holder from its closed position to its opened position upon the release of a latch provided for releasably retaining the holder in its closed position, and such fulcrum for the holder is shifted forwardly at an intermediate position of the holder in moving from its closed position to its opened position so that, even when the vertical dimension of the rectangular housing does not greatly exceed the corresponding dimension of the cassette to be contained in the receptacle, a lower-front corner of the holder will not extend below the housing in the opened position of the holder at which the latter is disposed for conveniently receiving or relinquishing a cassette in the holder. |
