Claims

[Scope of utility model registration request]

In a magnetic tape cassette that has an opening for inserting a magnetic head in the front side wall of a cassette case in which a pair of hubs wrapped with magnetic tape are built-in, at least a portion of the upper and lower edges of the front side wall are chamfered vertically symmetrically. It has an inclined part,
A cassette case includes a bearing portion formed on the outer surface of each of the left and right cassette side walls near the front of the cassette, and at least the upper and lower portions of the front wall, which has a substantially U-shaped horizontal cross section and consists of the front wall and the left and right end pieces, correspond to the inclined portions. a guard panel whose end pieces each protrude toward the cassette case, and which includes a rotary support shaft that engages with the bearing on the inside of each of the left and right end pieces, and is capable of swinging a volume to close the opening, and the cassette; a biasing means disposed on at least one side of the side wall and connected toward the rear of the cassette with respect to the rotational shaft of the left and right end pieces for biasing the guard panel toward the rear of the cassette, so that the entire cassette is symmetrical from front to back; 1. A magnetic tape cassette, wherein the upper and lower end pieces of the guard panel slide against the inclined portion of the cassette case when the opening is closed.
