摘要： A tape cassette having a synthetic resin casing accommodating a tape-like medium composed of an upper half casing, a lower half casing and a front lid, the upper and lower half casings being integrated by a plurality of fixing portions. A plurality of fixing portions are disposed at first positions which are outside of a second position of the front lid. Slackening of screw fixation of the upper and lower half casings is preventing and incapacitance in rotating the front lid due to melt-bonding of the front lid and the upper half casing is avoided.

摘要： A magnetic tape cartridge which is capable of permitting tape guides and a magnetic tape to exhibit resistance to wear and resistance to scraping sufficient to prevent the wearing of the tape guides and ensure the safe traveling of the magnetic tape over a long period of time, respectively. A polyester film forming a base of the magnetic tape contains a basic filler which absorbs a basic indicator bromothymol blue thereon while keeping it blue and a pair of the tape guides contacted with the polyester film are formed of ultra-high-molecular-weight polyolefin.

摘要： In a tape cartridge of the single-reel type having a hub on which a length of tape is wound, a brake mechanism contained in the hub is movable up and down to apply and release the brake on the tape reel. The brake mechanism and a brake lock release member disposed between it and the hub remain in sliding engagement after the release of the brake, and the resulting friction hampers smooth turning of the hub. Moreover, after the brake lock has been released, the center of the tape reel can be off the center of a rotating shaft of a recorder. The hub of the tape reel has holes formed in its bottom wall for engagement with the brake release plate, the brake release plate is mounted in the hub with legs fitted in the holes of the latter, the brake lock rests on the brake release plate, the brake lock is formed with a dent (or lug) with a spherical end and the brake release plate is formed with a corresponding lug (or dent) with a spherical end on its upper surface. A highly slippery sheet member is interposed between the contacting parts of the brake lock and the brake release plate.

摘要： A tape cartridge including a single tape reel around which a length of magnetic tape is wound and which is turnably held within a housing, the beginning of the tape being fixed to a leader so that it can be drawn out through an opening formed in the housing by a tape drawing-out member of a recorder which has a pin-like or hooked end capable of engaging the tape end, said leader comprising a center part (pin-like member) on which the beginning of the tape is wound and a pair of engaging members joined to the upper and lower ends of the member so as to engage the tape drawing-out member of the recorder, said engaging members having a plurality of recesses each for engaging the drawing-out member. Thus the engaging members can consist of members identical in structure. In another embodiment the center member has position-confining portions formed close to its both ends to confine the positions of the engaging members.

摘要： A tape reel for a tape cassette includes stabilizing ribs positioned on opposite sides of a deposition rib. The stabilizing ribs are lower in height than the deposition rib and are provided with an abutment surface which extends parallel to the joining surfaces of the reel hub and reel flange. As the deposition rib is melted to join the reel hub and reel flange together, the melt distributes uniformly between the joining surfaces of the reel hub and reel flange, thereby preventing any deformation of the tape reel, such as deflection and/or warpage of the outer periphery thereof. A simplified manufacturing process yielding uniform product quality results.

摘要： A tape cartridge includes a single tape reel around which a length of magnetic tape is wound and which is turnably held within a housing. The beginning of the tape is drawn out through an opening formed in the housing by a tape drawing-out member of a recorder. The drawing-out member has an engaging member at the outer end. The housing has a cell in which a hook member to catch an engaging end of a leader tape, when the leader tape holding the beginning of the magnetic tape is used, is detachably fitted and a cell in which a leader member to hold the beginning of the magnetic tape, when the leader member is used, is contained. The housing is made using a mold which forms a cell having a leader member holding the beginning of the magnetic tape or which forms the cell without the leader member.

摘要： A tape reel for a tape cassette wherein a pair of such reels are contained, comprising an upper flange and a hub which consists of a drum formed integrally with (formed in one piece with, or solidly joined to) a lower flange. The drum comprises an outer cylindrical part on which a tape is wound and an inner cylindrical part which permits the insertion of a driving shaft of a recording-reproducing device for the tape cassette. The inner cylindrical part has projections adapted to engage with the driving shaft, each said projection having a groove formed on the back side for thickness reduction, and the inner cylindrical part and inner ends and both side walls of the projections all have the same thickness. A plurality of connecting ribs are provided joining the outer and inner cylindrical parts of the drum, and extensions are formed outwardly on the inner cylindrical part, on both shoulder portions close to each said connecting rib. Alternatively, a plurality of ribs are formed along the inner circumference of the outer cylindrical part, extending from the outer cylindrical part toward, but short of, the inner cylindrical part.
