본 고안은 VTR의 제작시 메카니즘의 장력을 조정하는데 사용되는 비디오 테이프 장력 측정장치에 관한 것으로 특히 통상의 테이프 카세트와 같은 구조를 갖춘 카아트리지의 테이프 공급릴측에 태엽상의 탄성부에 탄지된 지침을 축설시키고, 공급릴측에서 공급되는 테이프가 지침에 걸쳐 공급되게 하여 테이프에 가해지는 장력이 지침으로 표시되도록 한 비디오 테이프 장력 측정 장치인 것이다.The present invention relates to a video tape tension measuring device used to adjust the tension of a mechanism in the manufacture of a VTR. In particular, a guide on the spring-loaded elastic part on the tape feeding reel side of a cartridge having a structure similar to that of a conventional tape cassette is constructed. And a tape supplied from the supply reel side is supplied over the guide so that the tension applied to the tape is indicated by the guide.
현재 VTR메카니즘의 테이프 장력 측정은 조립 기술자가 시각 또는 감각 정도로 장력을 측정하여 조립하고 있는 것으로 극히 원시적이고, 또한 정밀성이 없어 기구적인 작동이 원할하지 못한등의 문제점이 있었다.Currently, the tape tension measurement of the VTR mechanism is an assembly technician measuring and assembling the tension to a visual or sensory level, which is extremely primitive, and there is a problem that mechanical operation is not desired due to lack of precision.
본 고안은 이와 같은 문제점들을 감안하여 통상의 테이프 카세트와 동일한 구조를 갖는 카아트리지의 테이프공급 릴측에다 태엽식으로 판 스프링이 권회되어 구성된 탄성부에 탄지시킨 지침을 축설시키고, 이 지침과 공급릴의 후방측 각각에 회동 자재한 롤을 삼각지점상에 위치하도록 설치하고 공급 릴측에서 공급되는 테이프를 이들 롤들에 거쳐 공급되게 하여 테이프에 가해지는 장력이 지침에 의해 명확히 표시되고, 따라서 조정작업이 간단하고도 용이 할 뿐 아니라 조립에 정밀을 기할 수 있도록 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of these problems, the present invention lays out a guide on the elastic part formed by winding a leaf spring on the tape supply reel side of a cartridge having the same structure as a conventional tape cassette. Rotating rolls on each of the rear sides are placed on a triangular point, and the tape supplied from the supply reel side is fed through these rolls so that the tension applied to the tape is clearly indicated by the instructions, thus making adjustment simple. It is not only easy to devise a precision in the assembly as described in detail by the accompanying drawings as follows.
본 고안은 제1도에서와 같이 통상의 테이프 카세트와 동일한 구조를 갖는 일실시예의 카아트리지(1)의 공급릴(1-1)측에 원판상의 판체(2)을 조립식으로 고정 설치하고, 이 판체(2)의 중앙부에 관통공(2-1)과 주연 일측에 표시눈금(2-2)을 형성시키고 이와 같이된 원판상의 판체(2) 하부에 회동봉(3)을 브래킷트(4)로 회동자재하게 고정 축설하고 이 회동봉(3)을 일단 이 괘지봉(5)에 고정되는 태엽상의 탄성부(6)로 탄지시키되 상단부에 지침(7)을 축착 고정하는 한편, 지침(7)과 공급릴(1-1)의 후방측에 회동자재한 롤(8), (8-1), (8-2)을 삼각지점에 각각 설치하고 이들 롤(8), (8-1), (8-2)들에 테이프(T)가 걸쳐 통과되게 구성한 것으로 9은 카아트리지의 상면에 형성된 투시창이다.In the present invention, as shown in FIG. 1, the disc-shaped plate member 2 is fixedly installed on the supply reel 1-1 side of the cartridge 1 of the embodiment having the same structure as a conventional tape cassette. A through hole (2-1) is formed at the center of the plate (2) and a display scale (2-2) is formed at one side of the circumference, and the rotating rod (3) is attached to the lower portion of the plate-like plate (2). Rotate freely and securely and hold this pivoting rod (3) once with a spring-shaped elastic part (6) fixed to the hanging bar (5). The rolls 8, 8-1, and 8-2, which are rotated on the rear side of the feed reel 1-1, are provided at triangular points, respectively, and these rolls 8, 8-1, Tape (T) is passed through (8-2), and 9 is a viewing window formed on the upper surface of the cartridge.
이와 같이된 본 고안을 설명하면 다음과 같다.Referring to the present invention as described above is as follows.
본 고안은 VTR의 본체 조립이 완료되면 최종적으로 테이프의 주행 상태를 검사하게 되는데 이때 테이프의 장력 상태를 적절히 조정시키기 위한 측정기구로서 제1도에서와 같이 테이프(T)을 지침(7) 하부에 설치된 롤(8)과 공급릴(1-1)의 후방측에 설치된 롤(8-1), (8-2)들에 걸쳐서 공급되게 한다.In the present invention, when the assembly of the main body of the VTR is completed, the running state of the tape is finally inspected. At this time, the tape T is placed under the guide 7 as shown in FIG. The rolls 8-1 and 8-2 provided on the rear side of the roll 8 provided and the supply reel 1-1 are supplied.
이와 같이된 카아트리지(1)를 조립이 완료된 VTR의 본체에 로우딩 시키고 플레이버튼을 작동시키면 테이프(T)가 주행하게 되는 이때 테이프(T)에 장력이 증가하면 롤(8-1), (8-2)의 사이에 설치된 지침(7)이 테이프(T)의 장력에 의해 이동하게 되고 따라서 지침(7)에 의해 테이프의 장력 상태가 카아트리지(1)의 투시창(9)을 통하여 표시눈금(2-2)으로 표시되어 조립자가 이를 로고 간편하고도 용이하게 테이프 장력을 조정 시키게 되는 효과가 있는 것이고, 또한 테이프의 장력이 표시 눈금으로 표시되므로 테이프의 장력을 정확히 조정하여 정밀성을 기하고 조립 작업 시간 또한 단축시킬 수 있는 효과가 있는 것이다.When the cartridge 1 is loaded on the main body of the assembled VTR and the play button is operated, the tape T is driven. When the tension is increased on the tape T, the roll 8-1, ( The guideline 7 installed between 8-2) is moved by the tension of the tape T, and accordingly the guideline 7 causes the tension state of the tape to be displayed through the viewing window 9 of the cartridgeage 1. It is marked with (2-2), which makes it easy for the assembler to adjust the tape tension easily and easily. Also, since the tension of the tape is indicated by the marking scale, it is precisely adjusted by precisely adjusting the tension of the tape. It also has the effect of reducing work time.
