Claims

[Scope of Claim for Utility Model Registration] (Month) A magnetic tape consisting of an upper and lower half case that has a built-in pair of flangeless hubs wrapped with magnetic tape and an opening that allows the magnetic tape to be pulled out to the front of the cassette. In the cassette, a first guard panel having a U-shape in horizontal cross section is pivotally attached to the left and right side walls of the cassette near the front of the cassette, is movable upwardly of the cassette, is biased in a closing direction, and closes the front side of the opening; It consists of a lid part and a slide body part, which are equipped with a second guard valve that closes the lower side of the opening and protrudes in the thickness direction of the cassette up to the back side of the magnetic tape located in the opening, and urges the cassette forward. a plate-shaped second guard panel that slides in the cassette front-back direction along the inner surface of the bottom of the cassette; a storage recess that slidably accommodates the second guard panel; and a lower half that has a pair of reel shaft insertion holes. A case, an upper half case including a first guard valve protruding in the thickness direction of the cassette opposite to the second guard valve, and a friction sheet that covers the inner surface of the bottom of the cassette to which the second guard panel is attached. A magnetic tape cassette characterized in that: (2) the second guard valve is provided closer to the back surface of the magnetic tape than the first guard valve; magnetic tape cassette.
