Claims

[Scope of utility model registration request]

In a magnetic tape cassette that has an opening for inserting a magnetic head on the front side of a cassette case in which a pair of knobs wrapped with magnetic tape are built in, the cassette is placed near the front of each cassette on the left and right side walls of the cassette. The bearing, which is symmetrical with respect to the line that bisects the side wall vertically and bent in a dogleg shape toward the front of the cassette, is connected to the cassette case with a transparent hole, and the horizontal cross section is approximately U-shaped, and the bearing is located on the left and right sides of the cassette case. The bearing is provided at each end piece with a rotary support shaft that is slidable by engaging with the hole, and the base and tip of the rotary support shaft are formed in a flange having a diameter larger than the width of the hole. a guard panel that can swing up and down to close the opening; and a guard panel disposed on at least one of the side walls of the cassette and connected to a position closer to the rear of the cassette than the rotation axis of the end piece to attach the guard panel to the rear of the cassette. A magnetic tape cassette comprising a biasing means for biasing the tape, and characterized in that the entire cassette is symmetrical on the front and back.
