Claims

[Scope of utility model registration request]

It contains a pair of hubs around which magnetic tape is wound, a friction sheet and a locking member for locking the hubs, and has an opening that allows the magnetic tape to be pulled out to the front of the cassette. A magnetic tape cassette comprising a rotatable guard panel that closes the front side and a slidable slide guard that closes the lower side of the opening,
The locking member is provided with a locking portion that engages with an annular portion formed on the upper edge of the hub to stop the rotation of both hubs, and is slidable in the front and back direction of the cassette, and the slide guard is plate-shaped and locks the cassette case. The cassette is slidable in the longitudinal direction along the outer surface of the bottom, and a fulcrum part is locked to a boss protruding inside the cassette case, and one of the arms extending from the fulcrum part engages the locking member. 1. A magnetic tape cassette comprising an integral spring which biases the cassette rearwardly and whose other arm biases the slide guard forwardly.
