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 casing and a single reel which is contained in the cartridge casing for rotation. A brake component including brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear prevents rotation of the reel and a retracted position where the brake gear permits rotation of the reel. The brake member has an engagement surface which is conically inclined with respect to the axis of rotation of the reel.

摘要： A single reel with magnetic tape wound thereon is housed in a case. A restraining member, for restricting rotation of the reel by moving toward or away from the reel, is urged in a restraining direction by an urging member. The pushing-up portions of a releasing member are inserted into the through holes bored in the reel gear of the reel 2 so that the lower ends can abut a driving gear. The releasing member moves the restraining member in a releasing direction by moving according to the chucking operation of drive-side rotation drive means. In this manner, reel-rotation restraining means allows rotation of the reel when being used and restricts the rotation when not being used. In this construction, each of the through holes is bored between the tooth edges of the reel gear so that the releasing member can perform a reliable releasing operation.

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 includes a cartridge casing, a single reel which is housed in the cartridge casing for rotation and around which a magnetic tape is wound, the leader pin which is fixed to the leading end of the magnetic tape in order to draw out the magnetic tape from the cartridge casing, a lock member which is adapted to removably hold opposite ends of the leader pin inside an opening of the cartridge casing, and a sliding door for opening and closing the opening. A recess is formed on the inner surface of the sliding door at least at a part opposed to the front end of the lock member so that the front end of the lock member is prevented from interfering with the sliding door, whereby leader pin holding action by the lock member and opening and closing of the sliding door are stabilized and reliability of the magnetic tape cartridge is improved.
