摘要： A magnetic tape cartridge is constructed by rotatably housing a reel having magnetic tape wound therearound within a cartridge case. The cartridge case is constructed by an upper case and a lower case. The cartridge case has a tape extraction opening in a side wall thereof. The upper case and the lower case are fixed by welding at an abutment surface P, where the upper case and the lower case abut each other. In addition, vertically extending ribs that alternately extend up and down beyond the abutment surface P are provided on the inner surfaces of the side walls of the upper case and the lower case in the vicinity of the opening. By this construction, the strength of the cartridge case in the vicinity of the opening is improved, thereby preventing damage thereto even when the magnetic tape cartridge is dropped or the like.

摘要： A magnetic tape cartridge includes a reel around which a magnetic tape is wound, a cartridge case rotatably accommodating the reel, a reel lock for locking rotation of the reel relative to the cartridge case, a resilient member urging the reel lock toward the reel, a release pad for disengaging the reel lock by displacing the reel lock against an urging force of the resilient member, so as to allow rotation of the reel, and a pivot provided on the reel lock at a position facing with and slidably contacting a contact surface of the release pad in a manner allowing rotation of the release pad. The pivot and the contact surface are both made of resin, and the contact surface is made of a resin having a higher hardness than the pivot.

摘要： A magnetic tape cartridge is equipped with a cartridge, a single tape reel, a tape leader pin, and a U-shaped clip. The cartridge case is formed by fastening upper and lower cases of synthetic resin together and has a tape leader opening formed in the upper and lower side walls of the upper and lower cases. The single tape reel has magnetic tape wound thereon and is rotatably housed within the cartridge case. The tape leader pin is firmly attached to a leading end of the magnetic tape, and is detachably held in an upright state between the upper and lower cases so that it faces the tape leader opening. The U-shaped clip is attached to walls near the tape leader opening to fasten the upper and lower cases together, whereby the fastening strength of the upper and lower cases is enhanced.

摘要： A reel comprises a hub onto which recording tape is wound and a flange that is disposed on an end portion of the hub and retains a width-direction end portion of the recording tape, wherein plural cutout portions that locally divide the hub and the flange are formed in the flange. The cross section of the hub in plan view has a substantially equilateral triangular shape and positions where constricting force resulting from the tape reaches a maximum are caused to protrude in advance.

摘要： A cartridge case 1 for a magnetic tape cartridge comprises a cartridge case 1 consisting of a lower half 2 and an upper half 3. The lower half 2 is provided with retaining ribs 71 each having a retaining slanted surface 71a such that a plate-like cartridge memory 7 is positioned on the retaining slanted surfaces 71a with its one side 7d lowered and is obliquely supported with respect to a bottom plate 28 of the lower half 2. The upper half 3 is provided with supporting members for supporting various non-resilient constituent parts positioned on the lower half 2 and including the cartridge memory 7. The upper half 2 is provided with a stopper rod 77 such that when the upper half 3 is assembled with the lower half 2, the stopper rod 77 reaches a cartridge memory-rising region before the supporting members contact with the non-resilient constituent parts on the lower half 2.
