ABSTRACT:
A magnetic tape cassette particularly well adapted for use with digital audio magnetic tapes, which is small in size and easy to assemble. The cassette includes upper and lower half cases and a slide guard for covering a lower part of an opening through which the magnetic tape is extracted for recording and reproduction. The slide guard is in the form of a substantially U-shaped plate member having side pieces at its opposite ends which extend along side walls of the cassette. The slide guard is urged towards the front end of the cassette and is slidably mounted so as to be slidable forwardly and backwardly of the cassette. Overhangs are formed on upper edges of the side pieces of the slide guard confronting each other and which are received in the cassette through slits formed in the side walls of the cassette. Upper edges of the overhangs have the form of tapered surfaces inclined inwardly of the slide guard. The distance between the upper ends of the tapered surfaces is larger than the distance between the right and left parts of the lower half case on which the slide guard is mounted requiring flexing of the slide guard side pieces during mounting of the lower half case.
