Abstract
A continuous loop tape cassette for use with an external tape player/recorder apparatus, having a cassette base, a cover and a separate tape guide positioned therebetween. The separate tape guide includes an elongated bridge molded of a low friction plastic and having substantially planar top and bottom surfaces, left and right ends with curved, relatively flat, front surfaces which are slightly slanted relative to the substantially planar top and bottom bridge surfaces, and a flange formed integrally of the front top surface of each end. In addition, locating holes are formed at each left and right end to receive corresponding projections formed on the cassette base and to orient the bridge relative to the tape cassette. Finally, there is provided between the left and right ends a leaf spring having a relatively soft, tape contacting member thereon for exerting a uniform pressure on the running tape as it crosses the magnetic head of the external tape player/recorder apparatus. The curved, relatively flat, front surfaces of the left and right ends, together with the flange and tape contacting member define the tape guiding surface of the tape guide.
