Abstract:
A magnetic tape cassette in which a tape end detecting optical guide and a transparent window plate through which a tape winding state is viewed are coupled together by coupling members and of which all the components are made integral, of transparent resin. Thus, the number of assembly parts of the magnetic tape cassette is decreased and the assembling work thereof greatly simplified.
