본 고안은 비디오 테이프 카세트에 있어서 비디오 테이프의 케이스 내부에 설치되어 테이프를 보호하여 주는 릴의 유동에 대하여 적당한 탄성으로 릴을 압착시켜주는 비디오 테이프 카세트의 릴 지지용 스프링에 관한 것으로, 릴 지지용 스프링을 합성 수지등으로 사출 성형하여서 탄성을 양호하게 개선하고 카세트 내에 조립시 작업공정수를 줄일 수 있게 함으로써 생산 원가를 절감할 수 있게 한 것이다.The present invention relates to a reel support spring of a video tape cassette, which is installed inside a case of a video tape cassette and compresses the reel with moderate elasticity against a flow of reel that protects the tape. It is possible to reduce the production cost by injection molding with a synthetic resin to improve the elasticity and to reduce the number of working steps when assembling in the cassette.
종래의 릴 지지용 스프링을 제5도에서 보는 바와 같이 금속제의 박판을 사용하는 것으로 상부케이스(20)와의 결합을 위하여 홀(21)을 천공하고, 상부케이스(20)의 상부 내측면에는 돌기(22)를 돌설하여 상기한 홀(21)과 결합한 다음 돌출된 돌기(21)를 가열 용융하여 걸림턱(23)을 형성시키므로서 릴 지지용 스프링(24)을 결합하도록 한 것이다.As shown in FIG. 5, a conventional reel support spring is formed using a thin metal plate to drill holes 21 for coupling with the upper case 20, and a protrusion (not shown) on the upper inner surface of the upper case 20. 22 is to be coupled to the above-mentioned hole 21 and then heat-melt the protruding protrusion 21 to form a locking jaw (23) to combine the reel support spring (24).
이와같은 결합방법은 금속제의 릴 지지용 스프링(24)에 탄성을 주기위한 절곡부(25) 및 홀(21)을 형성하기 위한 프레싱등 별도의 공정을 거쳐야 하며 돌기(21)을 용융하고 걸림턱(23)을 형성하여 결합하기 위한 작업공정 및 작업시간이 많이 소요되어 생산성이 저하되고 원가 상승의 요인이 될뿐만아니라 릴 지지용 스프링(24)자체의 형상도 릴 지지에 따르는 탄성을 효과적으로 유지하기 어려운 문제점이 있는 것이다.Such a coupling method requires a separate process, such as pressing to form the bent portion 25 and the hole 21 to give elasticity to the reel support spring 24 made of metal. (23) It takes a lot of work process and work time to form and combine to reduce the productivity and increase the cost, as well as the shape of the reel support spring 24 itself to effectively maintain the elasticity according to the reel support There is a difficult problem.
본 고안은 상기한 바와같은 문제점을 해결하여 릴 지지용 스프링에 양호한 탄성을 부여 하면서 작업공정수를 감소하여 원가절감을 실현할 수 있는 비디오 테이프카세트의 릴 지지용 스프링을 제공하기 위한 것이다.The present invention is to provide a reel support spring of a video tape cassette that can solve the problems described above to provide a good elasticity to the reel support spring while reducing the number of working steps to realize cost savings.
본 고안은 이와같은 목적을 달성하기 위하여 비디오테이프의 상부케이스 내측면에 요입부를 천설하고 이에 결합되는 릴지지용 스프링은 강도 유지를 위한 보강편의 상부케이스와 결합되는 결합부와 돌기가 형성되게 합성수지등으로 일체로 성형하여 상부케이스와 결합이 되게 한 것이다.In order to achieve the above object, the present invention installs a recess in the upper surface of the upper case of the video tape, and the reel support spring coupled thereto is formed of a synthetic resin such that the coupling part and the protrusion formed with the upper case of the reinforcing piece for maintaining the strength. It is molded to be integral with the upper case.
이하, 본 고안의 구성 및 작용, 효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail.
하부케이스(1)의 내측 평면상의 하부릴(2)과 상부릴(3) 이 테이프(4)가 개재되고 릴 지지용 스프링(5)이 걸합되는 상부케이스(6)를 하부케이스(1)와 조립하여 상부케이스(6)에 결합된 릴 지지용 스프링(5)에 의하여 릴의 유동시 릴을 압착시켜 주도록 하는 공지의 비디오 테이프 카세트(7)에 릴 지지용 스프링(5)을 결합함에 있어서, 비디오 테이프 카세트(7)의 상부 케이스(6)상부 중앙 내측면에 적당한 깊이를 갖는 요입부(8)를 천설하고, 탄성을 부여하는 절곡부(9)가 형성되는 릴 지지용 스프링(5)을 합성수지등으로 일체로 성형하면서 그 중앙부에는 적당한 두께로 충분한 탄성과 강도를 부여하게 되는 보강편(10)의 상부에 상부케이스(6)의 요입부(8)와 결합되는 결합부(11)를 돌출시키고, 결합부(11)의 평면상에는 돌기(12)를 돌설하여서 된 것이다.The lower case 1 and the lower reel 2 and the upper reel 3 on the inner plane of the lower case 1 have an upper case 6 in which the tape 4 is interposed and the reel support spring 5 is fitted. In assembling the reel support spring 5 to a known video tape cassette 7 which assembles and compresses the reel when the reel flows by the reel support spring 5 coupled to the upper case 6. The reel support spring 5 in which the concave indentation 8 having a suitable depth is laid on the central inner side of the upper case 6 of the upper case 6 of the video tape cassette 7 is formed. While integrally molded with a synthetic resin or the like, the center portion protrudes the coupling portion 11 coupled with the recess 8 of the upper case 6 to the upper portion of the reinforcing piece 10 to give sufficient elasticity and strength to an appropriate thickness. The projections 12 are formed on the plane of the coupling portion 11.
이와같이 구성되는 본 고안은 제3도에서 보는 바와같이 릴 지지용 스프링(5)의 결합부(11)를 상부케이스(6)의 요입부(8)에 맞추고 돌기(12)를 요입부(8)에 융착시키므로서 릴 지지용 스프링(5)은 상부케이스(6)에 일체로 접착되면서 결합부(11)는 요입부(8)에 삽입되어 견고하게 고정될 수 있는 것이다.The present invention configured as described above, as shown in FIG. 3, aligns the engaging portion 11 of the reel support spring 5 with the recessed portion 8 of the upper case 6 and the projection 12 with the recessed portion 8. While the reel support spring (5) is integrally bonded to the upper case (6) while being fused to the coupling portion 11 is inserted into the concave portion (8) can be firmly fixed.
상기한 돌기(12)의 융착은 초음파 용접에 의한 방법으로 가능할 것이다.The fusion of the protrusion 12 will be possible by the ultrasonic welding method.
또한, 제4도는 본 고안의 다른 실시예를 예시한 단면도로서 도시한 바와같이 상부케이스(6)의 요입부(8)에 수용되게 돌설된 돌기(12)가 릴 지지용 스프링(5)의 평면상으로 형성된 결합부(11)와 용착하여도 가능하게 되는 것이다.In addition, Figure 4 is a plan view of the reel support spring 5 is a projection 12 protruding to be received in the recess 8 of the upper case 6 as shown in cross-sectional view illustrating another embodiment of the present invention It is also possible to weld with the coupling part 11 formed in the shape.
따라서, 본 고안의 릴 지지용 스프링(5)은 상부케이스(6)와 대면하는 보강편(10)의 형성으로 반복되는 휨응력에 대하여 충분한 강도를 유지하면서 결합부(11)가 요입부(8)에 삽입되면서 융착되므로 좌우의 흔들림에 대하여 견관 고정상태를 유지할 수 있고, 각부가 일체로 사출된 구조로 작업공정의 감소 및 생산성의 향상으로 원가를 절감할 수 있는 유용한 고안인 것이다.Therefore, the reel support spring 5 of the present invention has a coupling portion 11 recessed portion 8 while maintaining sufficient strength against repeated bending stresses due to the formation of the reinforcing piece 10 facing the upper case 6. Since it is fused while being inserted into it, it is possible to maintain the shoulder fixed state against left and right shaking, and it is a useful design that can reduce the cost by reducing the work process and improving productivity by the structure in which each part is integrally injected.
