摘要： A magnetic tape cartridge has a cartridge casing, a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation and a leader pin fixed to the leading end portion of the magnetic tape. The leader pin is provided at its opposite ends with engagement portions which are brought into engagement with a tape drawing mechanism of a recording and reproducing system when the magnetic tape cartridge is loaded in the recording and reproducing system. The end face of each engagement portion is provided with a recess at which the tape drawing mechanism chucks the leader pin.

摘要： A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation. A slide door for opening and closing a tape outlet opening is mounted on the cartridge casing to be linearly slidable along a door passage between a closing position where it closes the tape outlet opening and an opening position where it opens the tape outlet opening. A door spring for urging the slide door toward the closing position and holding the same in the closing position is disposed on the door passage.

摘要： 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.

摘要： A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves connected together, and a single reel around which a magnetic tape with a leader pin fixed to the leading end of the magnetic tape is wound and which is contained in the cartridge casing for rotation. The leader pin is removably held in a tape draw-out opening with its axial direction directed in the vertical direction under urging force of a spring member acting on its upper and lower end portions sideways with the upper and lower end portions received in recesses respectively formed in the upper and lower casing halves. An inclined surface directed obliquely downward is formed at least a part of the side wall of the recess formed in the upper casing half opposed to the direction in which the spring member urges the leader pin.

摘要： A magnetic tape cartridge includes a cartridge case, a single tape reel, and a tape leader pin. The cartridge case has a tape leader opening in the side wall thereof. The tape reel with magnetic tape wound thereon is rotatably housed within said cartridge case. The tape leader pin is firmly attached to the leading end of said magnetic tape and is detachably held near the tape leader opening by a spring member. The surface hardness of the sliding surface of the spring member with respect to said tape leader pin is made higher than that of the tape leader pin to prevent an increase in the sliding resistance between the sliding surface of the tape leader pin and the sliding surface of a leader-pin holding spring.
