れていた。 Conventional open reels are broadly divided into those in which the flange and hub are integrally molded from plastic, and those in the separate type in which the winding hub and double-sided flanges are assembled using separately manufactured top screws, etc. All-plastic reels are generally less accurate. Therefore, a high-precision open reel is a separate type. In other words, in the conventional separate type open reel, as shown in Figs. 1 and 2, a ring-shaped hub 1 of a constant thickness is manufactured from a hard plastic molding, aluminum die-casting, etc., and in some cases, a magnetic tape is applied to the outer circumferential surface. Synthetic rubber coating 2 for adhesion is applied. Note that 3 is a notch for fitting into a protrusion of a rotating shaft (not shown) of the device. Flanges 4, 4' (shown only in FIG. 2) for restraining the side surfaces of the magnetic tape are attached to both sides of the hub 1. In order to attach the flanges 4, 4', as shown in FIG. These flanges are fastened to the hub 1 by head screws. However, hubs are usually made by die casting or plastic molding, but with die casting, it is possible to avoid traces of melt flow, knock pin marks, etc., and with plastic, it is possible to avoid weld nozzle mouth marks, sink marks, knock pin marks, ribs for strength reinforcement, etc. In the case of plastic molding, the thickness is made as uniform as possible to eliminate molding distortion and sink marks. Therefore, the use of transparent flanges cannot hide these defects, and conventional flanges have been formed from metal such as aluminum plate or opaque plastic plate.

製造工程上もハブの面の仕上げが容易になる。 It is therefore an object of the present invention to provide a magnetic tape reel that does not have these drawbacks. The magnetic tape reel of the present invention has a winding hub with transparent flanges attached to both sides, and is characterized in that both sides of the winding hub are formed into grooves, and an opaque plastic annular insert is fitted into the grooves. According to the present invention, molding defects on both sides of the hub are hidden;
A transparent flange can be used, the insert body can have any color or design, and if the insert body is made of a slightly elastic plastic body, the elasticity of the plastic body can be used when tightening the flange screws. This makes it possible to finish the flange with a clean appearance without causing local distortion, and to tighten it without loosening. In addition, the conventional problem of meat stealing and ribbing on the surface of the hub can be done freely without having to worry about it, which improves the performance of the hub.Furthermore, the finish of the surface of the hub can be improved during the manufacturing process. becomes easier.

の利益を提供する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 3 is a front view of the tape-wrapped hub with the flange omitted, Figure 4 is a sectional view taken along line A-A' in Figure 3 with the flange attached, and Figure 5 is an enlarged view of Figure 3 along line B-B'. A cross-sectional view shows the flange attached. The magnetic tape reel 10 has a winding hub 11 and transparent flanges 14, 14' screwed to both sides thereof.
It consists of The hub 11 is an annular member made of a metal molded body such as aluminum die-casting or a hard plastic molded body. An annular groove 17 is formed on both sides of the hub 11 and has a substantially constant depth defined by inner and outer edges 12 and 16 extending in a plane that coincides with the plane of the transparent flange. The inner diameter of the hub 11 is sized to receive a rotating shaft (not shown), and has a notch 13 that fits into a protrusion of the shaft.
Correspondingly, the inner edge portion 12 is bent. Forming gate marks, sink marks, and other distortions may remain at the bottom of the hub groove 17. Furthermore, a plurality of screw insertion holes 15 are formed in the circular direction of the hub.
An annular plastic insert 18 of the same depth or slightly thicker as the groove 17 and of the same shape as the groove is fitted into the groove 17 on both sides of the hub. The material of the insert 18 is slightly elastic ABS.
It can be made from plastic materials such as, or in some cases, it can be made from glossy aluminum plate. Further, this annular insert 18 may be colored or may have a design printed on its surface. A portion corresponding to the insertion hole 15 is provided with a through hole 19 having a diameter slightly larger than the outer diameter of the screw to be inserted. Transparent flange 1
Reference numerals 4 and 14' are disk-shaped transparent bodies having a center hole that matches the inner diameter of the hub 10, and have through holes of the same size at the same locations as the insert body 11. The transparent flanges 14, 14' are attached to the insert 1 as shown in FIG.
8 to the hub 11 by screws 20, 20'. Insert 18 provides some cushioning, aids in tightening the screws, and also provides a cushion to prevent distortion of the flange around hole 15. Since the insert 18 is opaque, it has a beautiful finish.
By coloring or adding a design to this tape reel, it is possible to create a tape reel with a beautiful appearance, providing the above-mentioned benefits.
