ABSTRACT:
A magnetic tape cassette of the type in which the tape is pulled out of the front of the cassette for recording and playback having a simplified but more reliable structure made possible by combining functions of a winding body brake and tape end detector integrally in a single member. A winding body brake is composed of a pair of commonly pivoted braking sections, each having a braking claw and operating section. The two operating sections cooperate to close an opening in the cassette when the cassette is not in use. To play or record on the cassette, an insert is inserted into the hole, moving apart the operating sections and thereby disengaging the braking claws from the teeth of tape winding bodies on which the magnetic tape in the cassette is wound. The insert also includes a light source or sources for detecting the ends of the tape.
