본 고안은 비디오 테이프 카세트의 릴클램프 체결구조에 관한 것으로, 더욱 상세하게는 비디오 테이프 카세트의 공급릴과 감기릴의 허브면에 장착되어 비디오 테이프 양단에 일체로 연장되어 있는 리더테이프를 고정시켜 주는 비디오 테이프 카세트의 릴클램프 체결구조에 관한 것이다.The present invention relates to a reel clamp fastening structure of a video tape cassette, and more particularly, a video tape cassette is attached to a hub surface of a supply reel and a winding reel of a video tape cassette to fix a leader tape integrally extending at both ends of the video tape cassette. A reel clamp fastening structure of a tape cassette.

비디오 테이프 카세트에서 공급릴과 감기릴로 구분되는 릴(20)은, 제1도에 도시된 바와 같이, 릴상부판(21)과 릴하부판(22)으로 이루어져 있으며, 상기 릴하부판(22)의 중앙에는 비디오 테이프(23)가 권취되는 허브(24)가 돌설된 구조로 이루어져 있는데, 상기, 허브(24)의 외주연 일정위치에는 장착홈(25)이 형성되어 있어서 비디오 테이프(23)의 양끝에 형성되는 리더테이프(26)를 끼워 고정시키기 위한 릴클램프(27)가 장착된다.The reel 20, which is divided into a supply reel and a winding reel in a video tape cassette, is composed of a reel upper plate 21 and a reel lower plate 22, as shown in FIG. 1, and has a center of the reel lower plate 22. It has a structure in which the hub 24 is wound around the video tape 23, the mounting groove 25 is formed in the outer peripheral position of the hub 24 is formed on both ends of the video tape 23 A reel clamp 27 is fitted to fix the leader tape 26 to be formed.

이와같이 릴클램프(27)와 허브(24)상의 장착홈(25)으로 이루어지는 릴클램프 체결구조에서, 릴클램프(27)는 허브(24)의 외주연과 동일한 곡률반경을 갖는 테이프 접촉부(28)와, 장착시 허브(24)면에 형성된 장착홈(25)의 바닥면과 접하게 되는 체결부(29)로 이루어지는데, 종래의 릴클램프(27)는 제2도에 도시된 바와같이 상기 체결부(29)의 좌,우양단면에 외측으로 향하는 걸림부(30)가 돌설되어 있고, 허브(24)상의 장착홈(25) 양측면에는 내측으로 향하는 걸림턱(31)이 돌설되어 있어서, 릴클램프(27) 장착시, 상기 체결부(29)의 걸림부(30)와 장착홈(25)상의 걸림턱(31)이 서로 걸리게 되면서 이탈되지 않도록 되어 있다.In this reel clamp fastening structure consisting of the reel clamp 27 and the mounting groove 25 on the hub 24, the reel clamp 27 has a tape contact portion 28 having the same radius of curvature as the outer periphery of the hub 24. , The mounting portion 29 is in contact with the bottom surface of the mounting groove 25 formed on the surface of the hub 24, the conventional reel clamp 27 is shown in Figure 2 the fastening portion ( On the left and right end surfaces of the 29, a locking portion 30 facing outward is protruded, and a locking jaw 31 facing inward is protruded on both sides of the mounting groove 25 on the hub 24, so that the reel clamp 27 ) When mounting, the locking portion 30 of the fastening portion 29 and the locking jaw 31 on the mounting groove 25 are caught so as not to be separated.

그러나, 이와같은 종래의 릴클램프 체결구조에서는 제3도에 도시된 바와 같이, 릴클램프(27)의 체결부(29) 양단부에 형성된 걸림부(30)와 장착홈 좌,우면에 돌설된 걸림턱(31)의 돌출부분이 리더테이프(26)의 끊어짐을 방지하기 위하여 둥글게 곡면처리되어 있기 때문에 비디오 테이프(23)의 고속주행에 따른 장력증가시 릴클램프(27)가 그 결합상태로부터 쉽게 이탈된다는 결점이 있었고, 이에 따라 비디오 테이프(23)가 권취된 상태로부터 풀어지게 된다는 심각한 문제점이 제기되었다.However, in the conventional reel clamp fastening structure, as shown in FIG. 3, the locking projection 30 formed on both ends of the fastening portion 29 of the reel clamp 27 and the locking jaw protruding from the left and right sides of the mounting groove are shown. Since the protruding portion of the 31 is rounded to prevent the leader tape 26 from breaking, the reel clamp 27 is easily detached from the engaged state when the tension of the video tape 23 increases. There was a drawback, and serious problems were raised that the video tape 23 would be released from the wound state.

본 고안은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 릴클램프의 내곡면 중앙에 고정부재를 형성시키고 내곡면의 좌우양측에 일단이 외측으로 굽어진 체결편을 형성시키며, 또한 릴클램프가 체결되는 허브상의 장착홈 바닥면에는 대칭되게 가이드돌부를 형성시키고, 장착홈의 측면에는 내측으로 돌출된 형상의 걸림부를 형성시켜서 걸림부와 가이드돌부 사이의 체결편 삽입홈에 체결편이 삽입되고, 좌.우대칭인 가이드돌부 사이에 고정부재가 삽입되어 양체결편이 걸림부에 걸리고 가이드돌부와 고정부재의 상호 밀착력에 의해서 견고하게 리더테이프의 끼움상태를 유지하여 릴클램프의 이탈을 방지할 수 있는 릴클램프 체결구조를 제공하는데 본 고안의 목적이 있다.The present invention has been devised to solve such a conventional problem, to form a fixing member in the center of the inner curved surface of the reel clamp, and to form a fastening piece bent outward on both sides of the inner curved surface, and also the reel clamp The guide groove is formed symmetrically on the bottom of the mounting groove on the hub to be fastened, and the fastening piece is inserted into the fastening piece insertion groove between the locking portion and the guide protrusion by forming a locking portion protruding inwardly on the side of the mounting groove. The fixing member is inserted between the left and right symmetrical guide protrusions so that both fastenings are caught in the locking portion, and the leader tape is firmly held by the mutual adhesion between the guide protrusions and the fixing member, thereby preventing the reel clamp from being detached. It is an object of the present invention to provide a reel clamp fastening structure.
