Claims

[Scope of utility model registration request]

In a magnetic tape cassette having an opening that allows the magnetic tape wound around a pair of hubs to be pulled out in front of the cassette, the horizontal cross section is U-shaped, and the left and right end pieces are pivoted to the side walls of the cassette to form the opening. The first cassette can be opened upwardly and is biased in the closing direction.
A plate-shaped plate comprising a guard panel, a lid that closes the lower side of the opening, and a slide body located on the rear side of the cassette, and is slidable in the front and back direction of the cassette along the internal bottom surface of the cassette. a second guard panel, one end of which is pivotally connected near the reel shaft insertion hole and is rotatable along the inner bottom surface of the cassette, the free end of which abuts the slide body, and the side edge of which is in contact with the outer periphery of the hub; A pair of brake levers are symmetrically provided on the edge of the cassette so that they can be press-contacted from the rear side of the cassette, an elastic member that biases both brake levers toward the front of the cassette, and a bottom surface inside the cassette from above the second guard panel. A magnetic tape cassette comprising: a friction sheet covering the cassette; and a friction sheet covering the cassette.
