Claims

[Claims for Utility Model Registration] A reel hub includes a pair of reel hubs wound with magnetic tape, and a tape loading guide insertion portion for pulling out the magnetic tape forward is formed therein;
A cassette cassette body having a reel shaft insertion portion drilled on the lower surface side, a slider for opening and closing the lower surface side of the guide insertion portion and the reel shaft insertion hole, and a front cover for opening and closing the front side of the guide insertion portion. The slider slides along the outer bottom surface of the cassette case, and is biased in the closing direction by a torsion spring that engages with an engagement protrusion protruding from the inner surface on the front edge side. In the tape cassette, the engaging protrusion protruding from the slider has a hook-shaped upper part that protrudes rearward, and a guide piece extending upward is formed at the protruding end, and the torsion A tape cassette, characterized in that the end portion of the spring is brought into contact with and guided by the guide piece to be engaged with the engagement protrusion.
