ABSTRACT:
A magnetic tape cartridge, particularly for use in a digital audio tape player, which includes a lock mechanism for avoiding an arbitrary motion of any one of the reels within the cartridge so as to avoid an undesirable loosening of a length of the magnetic tape extending between the reels, The lock mechanism including a lock member normally biased to a lock position and having lock pawls normally engaged with toothed lock wheels integral with the respective reels, at least one stopper rod protruding from one end of the lock member and terminating in alignment with a free end of a corresponding one of hinge arms integral with a front cover used to selectively open and close a front opening of the cartridge such that so long as the front cover is in position to close the front opening, the free end of the stopper rod is positioned in close proximity to the corresponding hinge arm to keep the lock member immovable even when a drastic impact acts on the tape cartridge tending the lock member to move from the locked position towards an unlocked position.
