摘要： A cartridge includes a housing having a medium chamber defined therein for accommodating the recording medium and also having at least one access opening defined therein, a slide shutter slidably mounted on the housing for movement between an opened position in which the access opening is opened and a closed position in which the access opening is closed, and a biasing member for biasing the slide shutter towards the closed position. The biasing member is in the form of a twin-coiled torsional spring including first and second coils connected together by means of a bridge and first and second spring arms extending outwardly from the first and second coils, respectively. The first spring arm has a free end engaged to the slide shutter and the second spring arm has a free end engaged to a portion of the housing.

摘要： A magnetic tape cartridge, particularly the one for use in a digital audio tape player, includes a lock mechanism for avoiding an arbitrary motion of any one of the reels within the cartridge thereby to avoid an undesirable loosening of a length of magnetic tape extending between the reels. This lock mechanism includes a lock member normally biased to a lock position and having lock pawls normally engaged with toothed lock wheels integral with the respective reels. The lock member also has 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. When and 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 of the free end of 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 lock position towards an unlock position.
