Abstract
A magnetic tape cartridge with an improved reel-rotation restraining mechanism is disclosed. The reel-rotation restraining mechanism has a reel locking member, which is movable toward and away from the reel, for restricting rotation thereof; an urging member for urging the reel locking member in a restraining direction; and an releasing member, which is rotatable integrally with the reel, for moving the reel locking member in an unlocking direction by moving according to a chucking operation of a rotation drive mechanism of a drive unit. The releasing member has three leg portions on the vertexes of a triangular plate portion insertable into through holes in the reel. The releasing member is sized so that with part of the releasing member inserted into a center opening of the reel, and two of the three leg portions positioned near the through holes, the remaining one leg portion can be dropped and inserted within the center opening.
