摘要:
A tape cartridge has a right and left pair of reels 3 around which a tape 2 is wound, within a casing 1 equipped with a front cover 7. A reel lock mechanism 19 is provided within the casing 1 for preventing the reels 3, 3 from rotating. A release member 30 is disposed on the inner, upper face of the bottom wall of the casing 1 so as to be movable back and forth. A slider 9 for opening and closing the lower face of the pocket 6 for tape loading is fitted to the outer, lower face of the bottom wall of the casing 1 so as to be movable back and forth. When the slider 9 moves backward, the release member 30 is moved backward nearly at the terminating end of the backward travel stroke of the slider 9. With the backward movement of the release member 30, the reel lock mechanism 19 is moved, thereby releasing the reels 3, 3 from locking for rotation. Thus, while the front cover 7 is kept from any excessive upward opening force, the reels 3, 3 can be locked and released for rotation by the movement of the slider 9.
