ABSTRACT:
A magnetic tape cassette is provided with a reel brake and a tape-protecting lid. The tape-protecting lid has side plates extending parallel to the side walls of the cassette casing and pivoted on the side walls. The reel brake mechanism comprises a brake plate free to move between a braking position and a brake-release position and normally biased toward the braking position. One of the reel brake plate and the side wall of the casing is provided with means for maintaining interengagement between the reel brake plate and the side wall so as to ensure cooperation therebetween for automatic brake release in response to opening of the tape-protecting lid.
