Abstract
A tape cassette for a magnetic recording and/or reproducing apparatus, such as a video tape recorder. The cassette has at least one reel contained in a cassette casing formed with an opening through which a magnetic tape wound on the reel can be withdrawn from the casing for the recording of signals thereon or the reproducing of signals therefrom. A pivotally mounted member disposed within the casing comprises a brake lever for preventing the reel from rotating when the cassette is not in use. A helical compression spring normally urges the pivotally mounted member to rotate so as to bring the brake lever into engagement with teeth formed on a flange of the reel, and means is provided to overcome the action of the spring and release the brake lever from the reel when the cassette is to be used.
