Abstract
In a tape cassette, a reel brake member has an opening hole portion for insertion of a brake release member on a device side, and a guide recessed portion for guiding the brake release member is formed in a central portion of an abutment side wall portion of the brake release member in the opening hole portion. This guide recessed portion is formed in the abutment side wall portion of the brake release member in a vertical direction in a central portion of the opening hole portion, and an internal surface of the guide recessed portion is formed into a U-shaped groove having a curved surface. Arms are provided on sides of a main body of a reel brake member via hinge portions, and a brake pawl is provided at a distal end of the respective brake pawls. An opening hole is formed for insertion of a brake release operation member provided on a device side. In addition, upper surface portion and lower surface portion are provided which are adapted to abut with and slide over internal surfaces of upper and lower cases. Recessed portions are provided on the upper surface portion on both sides of a front side at positions corresponding to outer circumferential edges of the tape reels, and a butt recessed portion is provided on a front side of the lower surface portion so as to correspond to holding ribs provided along tape reel receiving areas on a front side of a reel brake sliding area.
