<p>A tape cassette suitable for digital recording and playback which require high reliability, since it has interchangeability in dimensions and shape with the conventional compact cassettes, is provided with the shutter member which selectively opens and closes the insertion window for the magnetic heads and pinch rollers, but is normally urged in the direction of closing, thereby to prevent dust, etc. from entering. Moreover, since the shutter member is arranged to slide in the direction of tape travelling, there is no increase in the volume of the tape cassette, even during opening or closing of the shutter member thus also contributing to size reduction of the compact cassette. <IMAGE></p> |
