ABSTRACT:
A tape cassette consisting of two cassette halves containing a pair of tape reels around which a length of tape is wound. Columnar pivots are formed upright on an inner wall of one of the cassette halves to turnably support reel detents which keep the tape reels from turning when the tape cassette is not in use. Each of the pivots is formed with an axially extending groove for cooling the pivot at a rate substantially equal to a cooling rate of the cassette halves. Each of the grooves has a width substantially uniform throughout an axial length of the pivot.
