ABSTRACT:
A tape cassette capable of ensuring smooth guiding of a reel brake member arranged in a casing while being simplified in structure and exhibiting an attractive appearance sufficient to increase a commercial value thereof. A reel brake member for selectively restraining rotation of tape reels received in a casing is arranged in the casing so as to be engageable with the tape reels to keep a tape from being loosened. Ribs are arranged in an upper casing member in a manner to be remote from gate positions, at which gates of a molding die for molding the casing are located, and contiguous to a rear wall of the upper casing member. A portion of the upper casing member surrounded by the ribs is reduced in thickness as compared to the remaining portion of the upper casing member.
