Claims

[Claims for Utility Model Registration] A tape protection lid is attached to the cassette body so as to be openable and closable and is opened when the cassette is installed in a tape player, and a brake release protrusion is formed on the inner surface of the side plate of this lid. In a cassette in which this brake release protrusion engages with a protrusion provided on a brake release member provided in the cassette that prevents rotation of the tape take-up reel, the width of the lid is set to A cassette characterized in that the width is narrower than the width of the cassette body by a dimension equal to or larger than the protrusion of the protrusion.
