摘要： 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.

摘要： A single-reel tape cartridge includes a rectangular flattened casing including upper and lower panels joined together to define a reel chamber therebetween. A tape reel includes a cylindrical hollow boss and upper and lower flanges protruding radially outwardly from upper and lower ends of the hollow boss, respectively, and is accommodated rotatably within the reel chamber. A drive ring is disposed at a lower portion of a hollow of the hollow boss and adapted to receive a rotary drive from a drive element of a tape drive mechanism when the drive element is brought into engagement with the drive ring in a planar contact fashion. This drive ring is supported in a fashion slidable up and down, but non-rotatable relative to the hollow boss. A reel retainer is biased by a biasing spring in one direction towards the lower panel of the casing, such that the drive ring can be sandwiched between the drive element and the reel retainer while the drive element is held in tight contact with an undersurface of the drive ring.

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 arms 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 single-reel tape cartridge cooperable with an operatively compatible tape drive including a tape catch member (50) includes a cartridge housing (1) having a tape window (4) defined therein and accommodating therein a single reel (2) with a roll of a length of magnetic recording tape (3) thereon. A leader member (13) includes a metallic leader pin (14) extending in a direction orthogonal to a lengthwise direction of the magnetic tape and first and second hooking arms (15). The leader pin has opposite ends thereof insert-molded into the first and second hooking arms (15) to thereby connect the leader pin with the first and second hooking arms (15) so as to represent a generally U-shaped configuration.
