摘要： In the magnetic tape cassette, upper and lower flanges 23a to 24c forming a tape reel 21 are formed alternately at a given angle in the two end portions of a reel hub 22 so that engaging gears 25a to 26c respectively formed on the outer peripheral edge portions of the upper and lower flanges 23a to 24c are substantially continuous in a plan view, and a brake claw is arranged so as to be engageable with any one of the engaging gears 25a to 26c regardless of the rotational position of the tape reel 21.

摘要： A reel flange for a magnetic tape cassette reel has apertures for viewing the tape on the reel. The apertures provide a system for visually estimating the quantity of tape contained on the reel. The flange provides the combined advantages of greater choice of materials for making the flange and improved accuracy in estimating the quantity of tape contained on the reel.

摘要： A self-locking hub for a computer tape drive that uses tape tension along to actuate a tape reel torque lock. In a preferred embodiment of the invention, the torque provided by tape tension after tape is threaded from a supply reel to a take-up reel provides sufficient force to actuate an over-center, spring-tensioned engagement pawl-like hub lock mechanism that engages an inner surface of a tape reel with sufficient force to secure the reel to the hub. More than one such self-locking mechanism may be provided for a single hub to provide additional locking force. In an alternative embodiment, the self-locking engagement pawl can include an engagement flange that prevents a tape reel from being pulled off the hub or from falling off a vertically-oriented hub, thus providing additional security. In yet another embodiment of the invention, the hub lock mechanism comprises a deformable torque clutch that deforms to an expanded diameter upon application of torque in one direction, and returns to a smaller at-rest diameter upon release of such applied torque.

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 flangless winding core for magnetic tape is adapted for stacking between like winding cores. The core has an annular body with top and bottom annular body surfaces, an outer circumferential surface to wind the tape thereabout, and an inner circumferential surface from which each of a plurality of equidistant projections with high and low circular extensions extends in the outward directions of the top and bottom annular body surfaces and a like plurality of recesses with two circular notches in the both edges thereof and corresponding to the high and low circular extensions are arranged in a space adjacent to the projections, so that the recesses can be consequently corresponded to the projections at the time of stacking the cores. The projections are inserted and interlocked with the opposite recesses when stacking the cores, so that they can prevent the cores from being shaken by exterior power from the circumferential direction, and the extensions on the projections and the notches on the recesses increase facing area for firm interlocking of the cores, and the notches give spaces for driving pins to be inserted when the cores are mounted on the processing equipments such as cutting machines or rewinders.

摘要： A flangeless-type reel holder for a device manufacturing reels of video film including a ring-type leaf spring fitted around the reel holder. The reel holder is fitted around a sleeve mounted on a drive shaft of the device, by means of a bearing interposed therebetween. The reel holder is directly coupled to the outer rim of the bearing. The outer diameter of the leaf spring fitted around the reel holder is larger than that of an annular rim of the reel holder so that the inner peripheral surface of a reel hub to be fitted around the reel holder can closely contact with the outer surface of the leaf spring.
