Abstract
In a single-reel type tape cartridge, a floating-lock structure comprising lock pieces and a lock spring for locking and biasing the lock pieces is provided between an upper surface of a tape reel and an upper case. On each of the lock piece are provided a restriction member for restricting upward movement of the tape reel and a releaser that is subjected to an unlocking operation performed an unlock member in a tape drive. Entry grooves for the unlock members are formed on an outer surface of the upper case, and the releasers are exposed in the entry grooves from operation openings provided in part of the entry grooves. When a main body case is loaded in the tape drive, the releasers are subjected to the unlocking operation by the unlock members so that the restriction members can move and evacuate upward in a hub space surrounded by a reel hub.
