Abstract
A miniature video magnetic tape cassette which is easy to assemble. An opening is formed in a front part of a cassette body which is covered by a guard panel, with the guard panel being swingably supported on the cassette body by shafts protruding from an inner surface of the side walls of the guard panel fitted into openings in the cassette body. A coil spring is supported on each supporting shaft with one end of each spring engaged with the guard panel to urge the guard panel toward the closed position of the opening. The other end of each coil spring is held by a locking structure provided on an inner surface adjacent to side wall of the upper half of the cassette body. The locking structure may be a locking shaft with the other end of the coil spring engaged with the locking shaft. Otherwise, the locking structure can be formed by a gap between the side wall of the upper half of the cassette and a supporting side wall inwardly thereof, in which case the other end of the coil spring is inserted into the gap and fixedly held therein with a block fitted in the gap.
