ABSTRACT:
A reel lock mechanism in a tape cassette locks a pair of tape reels against rotation to prevent a tape wound around the tape reels from being loosened. The reel lock mechanism has a reel lock assembly movable between a lock position to lock the tape reels against rotation and an unlock position to unlock the tape reels for rotation. The reel lock assembly includes a slider slidably supported in the tape cassette, a lock body having a pair of engaging members engageable with teeth on outer circumferential edges of the tape reels, and a twistable joint, the slider and the lock body being integrally connected to each other by the twistable joint. When one of the tape reels is turned in a direction to loosen the tape, one of the engaging members is displaced by one of the teeth on the one of the tape reels, twisting the joint to press the other engaging member against one of the teeth on the other tape reel for thereby turning the other tape reel in a direction to tension the tape.
