Claims

[Scope of utility model registration request]

A first guard panel having a U-shaped horizontal cross section and a second guard panel having a plate shape and having an opening that allows the magnetic tape wound around a pair of hubs to be pulled out to the front of the cassette, and which can close the opening. and a locking member for locking the first guard panel.In the magnetic tape cassette, the left and right end pieces of the first guard panel are pivoted to the side walls of the cassette and biased in the closing direction. The second guard panel is biased toward the front of the kayak and is slidable in the longitudinal direction of the cassette along the inner bottom surface of the cassette, and the locking member protrudes from the side wall hole to the outside of the case. has a locking part that fits into the engaging part of the end piece and a sliding contact part that slides against the side edge of the second guard panel, and is inserted into at least one of the support shafts protruding from the left and right sides of the opening. is fitted so that it can pivot along the bottom surface of the cassette, and is biased in a direction to project the engaging portion out of the case;
By fitting a guide sleeve, which is made of a material with excellent wear resistance and guides tape travel by slidingly contacting the back surface of the tape, onto the support shaft, the locking member is lifted from the bottom surface of the cassette at the edge of the support shaft. A magnetic tape cassette characterized by preventing.
