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： Disclosed herein is a magnetic tape cartridge including a reel-rotation restraining member which restricts rotation of a reel when not used and allows the rotation of the reel when used. The reel-rotation restraining member has a restraining member, an urging member, and an unlocking member. The restraining member has a restraining gear which meshes with a locking tooth portion, and the restraining member is supported by a support portion of the cartridge case. In the magnetic tape cartridge, the following relationship is met: b≦(2×a×c)/d where “a” represents the length of engagement between the restraining member in an unlocked state and the support portion, “b” represents the clearance between the restraining member and the support portion, “c” represents the space between the tooth of the restraining gear and the locking tooth portion, and “d” represents the outside diameter of the restraining gear.

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 includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. The reel has a reel hub in the form of a cylindrical member which has a bottom wall and is provided with an opening and a stopper gear formed on the bottom wall. A brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear is brought into engagement with the stopper gear to prevent rotation of the reel and a retracted position where the brake gear is disengaged from the stopper gear to permit rotation of the reel. The brake member is normally urged toward the operative position and moved to the retracted position by a pusher member of a tape drive system which acts on the brake member through the opening in the reel hub when the magnetic tape cartridge is loaded in the tape drive system. A continuous wall portion is erected around the opening in the reel hub, and the brake member includes a horizontal portion and a continuous skirt portion which extends downward from the horizontal portion and is in contact with the continuous wall portion of the reel hub to close the opening together with the horizontal portion. The brake member is moved between the operative position and the retracted position with the skirt portion kept in cotact with the continuous wall portion of the reel hub.
