Claims

[Scope of utility model registration request]

a cassette body in which a magnetic tape wound around a pair of hubs is housed in a case, and the magnetic tape is exposed on a tape running surface which is one end surface of the case; and a cassette body provided on the tape running surface. It consists of a guard section that is substantially parallel to the tape running surface and both ends that are substantially perpendicular to the guard section, so that the guard section can take an open position where the magnetic tape is exposed and a closed position where the magnetic tape is covered. a guard cover whose both ends are rotatably supported by the cassette body; a recess is provided on an inner wall surface of at least one of both ends of the guard cover, and a locking protrusion that can be engaged with the recess is provided. and a cover lock plate movably provided within the case so that the locking protrusion can assume a first position in which it engages with the recess and a second position in which it retreats outward from the recess. In the tape cassette, at least one end of the cover lock plate is fixed within the cassette body and held at the first position, and an elastic thin part is formed near the one end, and the thin part is bent by an external force. A magnetic tape cassette, characterized in that the magnetic tape cassette can assume the second position by being rotated.
