본 고안은 비디오 테이프 카세트의 릴클램프 체결구조에 관한 것으로, 더욱 상세하게는 비디오 테이프 카세트의 공급릴과 감기릴의 허브면에 장착되어 비디오 테이프의 양단에 일체로 연설된 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 mounted on a hub surface of a supply reel and a winding reel of a video tape cassette to fix a leader tape integrally integrated at both ends of the video tape cassette. A reel clamp fastening structure of a tape cassette.

비디오 테이프 카세트에서 공급릴과 감기릴로 구분되는 테이프릴(20)은, 제1도에 도시한 바와 같이, 릴상부판(21)과 릴하부판(22)으로 구성되어 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 연장 형성되는 리더테이프(26)를 끼워 고정시키기 위한 릴클램프(27)가 장착된다.In the video tape cassette, the tape reel 20 divided into a supply reel and a winding reel is composed of a reel upper plate 21 and a reel lower plate 22, as shown in FIG. 1. The center of the reel lower plate 22 has a structure in which the hub 24 on which the video tape 23 is wound is formed, and the mounting groove 25 is formed at a predetermined position on the outer circumference of the hub 24. Reel clamps 27 for mounting and fixing the leader tapes 26 extending on both ends of the video tape 23 are mounted.

이와 같이, 릴클램프(27)와 허브(24)상의 장착홈(25)으로 이루어지는 릴클램프 체결구조에서 릴클램프(27)는 허브(24)의 외주연과 동일한 곡률 반경을 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 바와 같이 상기 체결부(29)의 좌.우 양단면에 외측으로 향하는 걸림부(30)가 돌설되고 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 걸림홈(31)이 서로 걸리게 되면서 이탈되지 않도록 되어 있다.As such, in the 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 circumference of the hub 24. And, when the mounting consists of a fastening portion 29 which 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 the fastening portion as shown in FIG. On both left and right end faces of the 29, outwardly engaging parts 30 are protruded, and on both sides of the mounting groove 25 on the hub 24 are protruded inwardly and the engaging jaws 31 are protruded. (27) During mounting, the locking portion 30 of the fastening portion 29 and the locking groove 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(25) 좌.우면에 돌설된 걸림턱(31)의 돌출부분이 리더테이프(26)의 끊어짐을 방지하기 위하여 둥글게 면처리 되어 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 left and right sides of the engaging portion 30 and the mounting groove 25 formed at both ends of the fastening portion 29 of the reel clamp 27 are protruded. Since the protruding portion of the locking jaw 31 is rounded in order to prevent the leader tape 26 from breaking, the reel clamp 27 is released from the engaged state when the tension increases due to the high-speed running of the video tape 23. There was a drawback of being easily detached, and thus serious problems were raised that the video tape 23 would be released from the wound state.

본 고안은 상기와 같은 종래 릴클램프 체결구조의 문제점을 해소하기 위하여 안출되었으며, 리더테이프의 끼움상태를 확고히 유지할 수 있는 클램핑력이 강한 릴클램프 체결구조를 제공하는데 본 고안의 목적이 있다.The present invention has been devised to solve the problems of the conventional reel clamp fastening structure as described above, and an object of the present invention is to provide a reel clamp fastening structure with a strong clamping force capable of firmly maintaining the fitted state of the leader tape.

상기의 목적을 달성하기 위하여 본 고안은 릴클램프의 내곡면 양측에 좌.우 대칭 형상으로 지지편을 하측으로 형성하고, 지지편의 하단에는 걸림부와 조임부를 형성시킨 체결편을 지지편과 일체로 형성시키며, 상기 릴클램프가 체결되는 허브상의 장착홈 저면 중앙에는 상부에 구형의 돌기부를 형성시킨 포스트를 수직으로 형성시키고 장착홈의 양측면 하단에는 걸림홈을 형성시킨 새로운 형태의 릴클램프 체결구조를 제공한다.In order to achieve the above object, the present invention forms a support piece in the left and right symmetrical shapes on both sides of the inner curved surface of the reel clamp, and a fastening piece formed with a locking part and a fastening part at the lower end of the support piece is integrated with the support piece. And a new form of reel clamp fastening structure in which a post having a spherical protrusion is formed vertically at the center of the bottom of the mounting groove on the hub to which the reel clamp is fastened, and a locking groove is formed at the bottom of both sides of the mounting groove. to provide.
