Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a cassette tape used by being attached to a cassette tape recorder, and particularly to a cassette, which is a container in which magnetic tape is stored. (b) Prior Art Cassette-type tape recorders that use a cassette tape in which a magnetic tape is stored in a container called a cassette are popular, but such a cassette is made by combining a pair of members called a cassette half. It is composed of. and,
Such cassette halves are generally molded from synthetic resin, but recently some have been molded by primary molding and secondary molding, and such techniques are described, for example, in Japanese Utility Model Application Publication No. 12875/1983. Something has been disclosed. (c) Problems to be solved by the invention The above-mentioned publication discloses a technique for forming a cassette half by primary forming and secondary forming.
A cassette with excellent strength etc. is obtained by molding the cassette tape using multiple steps, and no consideration is given to the aesthetic appearance of the cassette tape or the confirmation of the winding state of the magnetic tape. The present invention aims to provide a cassette tape cassette that is improved in this respect. (d) Means for solving the problem The present invention includes a bulge in which a capstan hole and a guide hole are formed, and a connecting part that is connected from the bulge to surround a magnetic tape storage section. a base portion which is primarily molded from a colored resin, and a reel hole that covers at least the continuous portion and the magnetic tape storage portion and into which the reel shaft is inserted, and which is secondarily molded from a transparent resin. It is composed of a cover section. (E) Effect The present invention prevents the occurrence of peeling by molding the continuous portion of the base portion so as to be inserted into the cover portion. (F) Example Fig. 1 is a plan view showing the cassette of the present invention, Fig. 2 is a plan view showing the base portion constituting the present invention,
FIG. 3 is a plan view showing the cover part constituting the present invention, and FIG. 4 is a cross-sectional view of the cassette half taken along line A-A' in FIG. In the figure, 1 is a base part formed by primary molding, and includes a bulging part 6 in which capstan holes 2 and 3 into which a capstan is inserted and guide holes 4 and 5 into which a guide pin is inserted are formed. It is composed of a continuous portion 8 which is continuous from the bulging portion 6 so as to surround the magnetic tape storage portion 7. Reference numeral 9 denotes a front outer shape portion in which the bulged portion 6 is formed, and constitutes a part of the outer shape of the cassette. 1
0, 11, and 12 are screw holes formed in the bulging portion 6 and the front external portion 9 that constitute the base portion 1 . Although the base part 1 is configured in this way,
Next, the cover portion 13 formed by secondary molding will be explained. The cover part 13 is attached to the base part 1
It is configured to cover the continuous portion 8 and the magnetic tape storage portion 7 formed in the base portion 1, and to form the outer shape of the cassette together with the front outer shape portion 9 of the base portion 1. 14 and 15 are reel holes formed at positions corresponding to the reel axis on the cover surface that covers the storage section 7 provided in the base section 1 of the cover section 13 , 16 and 17 are screw holes, and 18 is a screw hole. This is an erasure prevention claw. The base portion 1 and cover portion 13 constituting the cassette of the present invention are constructed as described above, and the forming operation will now be described. First, the base portion 1 is molded by primary molding, and the base portion 1 is molded from a colored resin such as blue or green. After the base part 1 is primarily molded from a colored resin, the cover part 13 is molded by secondary molding, and the cover part 13 is molded from a transparent resin. Although one cassette half is formed by such primary and secondary forming, the other cassette half is also formed in the same manner. The cover part 13 is fixedly molded to the base part 1 which has been formed in this way by secondary molding.
The mold is configured such that a part 8a of the continuous portion 8 is inserted into the cover portion 13 as shown in FIG. When the reel hubs 19, 20 and the magnetic tape T wound around the reel hubs 19, 20 are inserted between the cassette halves formed in this way, the cassette halves are combined, as shown in FIG. The shown cassette tape is constructed, and the cassette halves are combined and fixed using screw holes 10, 11, 12, 16 and 1.
This is done by tightening screws (not shown) to 7. As is clear from FIG. 1 , the magnetic tape T and reel hub 19 are inserted through the transparent cover part 13.
20, but also the continuous portion 8 of the base portion 1 , which is molded from colored resin, can be seen through. Therefore, the reel hub 19,
By changing the shape of the base portion 1 as well as the cassette 20, cassettes with various designs can be obtained. (g) Effects of the invention The cassette of the invention has a bulging part in which a capstan hole and a guide hole are formed, and a cassette that is connected from the bulging part so as to surround a storage part for a magnetic tape wound around a reel hub. After primary molding the base portion consisting of the continuous portion with colored resin, a reel hole is formed which covers at least the continuous portion and the magnetic tape storage portion and rotatably supports a reel hub that engages with the reel shaft. By second-molding the cover part made of transparent resin, the magnetic tape stored in the storage part, the entire reel hub, and the connecting part can be viewed from the outside, so that the magnetic tape can be seen through. The present invention has the advantage that it is not only possible to easily check the remaining amount of reel, but also that it is possible to manufacture cassettes with various different designs by changing the color of the reel hub or adding patterns to the reel hub. ing. In addition, since the continuous part constituting the base part that is primarily molded is configured to be inserted into the cover part, the contact area between the base part and the cover part is widened, and as a result, the base part It is possible to prevent the occurrence of a peeling phenomenon between the cover part and the cover part, and the practical value of the present invention is very high.
