본 고안은 8mm용 VTR에 사용되는 MP테이프(Metal Powder tape) 또는 ME테이프(Metal Evaporated tape)를 공용으로 사용할 수 있도록 테이프의 마찰계수에 따라 테이프의 백텐숀을 조절하기 위한 VTR테이프의 텐숀변환장치에 관한 것이다.The present invention is a tension converter of VTR tape to adjust the back tension of tape according to the coefficient of friction of tape so that MP tape (Metal Powder tape) or ME tape (Metal Evaporated tape) used in 8mm VTR can be used in common. It is about.
일반적으로 8mm VTR의 헤드드럼의 입구측에 테이프의 백텐숀을 관리하는 것이 중요하다.In general, it is important to manage the back tension of the tape at the inlet side of the head drum of the 8mm VTR.
이러한 것은 공용으로 사용되는 ME테이프는 마찰계수가 크고 MP테이프는 마찰계수가 작으며 마찰계수가 크면 그 만큼 테이프의 텐숀도 높아지기 때문에 테이프의 텐숀을 마찰계수에 따라 적당히 조절하는 것이 필요하다.It is necessary to adjust the tension of the tape according to the coefficient of friction because ME tape used in common has a large coefficient of friction and MP tape has a small coefficient of friction, and a large coefficient of friction increases the tension of the tape.
그러나 종래에는 한세트내에 두 종류의 테이프를 사용할 수가 없어서 그 세트에 맞는 테이프만을 사용하여야 하거나 테이프에 알맞는 세트를 가진 VTR테이프로서 녹화 또는 재생을 하여야만 되는 결점이 있었다.However, in the related art, two types of tapes cannot be used in one set, and therefore, only the tape suitable for the set has to be used, or there is a drawback of recording or playing back as a VTR tape having a suitable set for the tape.
본 고안은 상기와 같은 결점을 해결하여 한세트로서 두 종류의 테이프(ME테이프, MP테이프)를 사용할 수 있도록 VTR세트내에 테이프의 텐숀 변환장치를 설치한 것으로서 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.The present invention solves the above drawbacks and installs the tension converter of the tape in the VTR set so that two types of tapes (ME tape and MP tape) can be used as one set. .
VTR카세트(A)를 장착할 수 있게한 세트내측에 안내로울러(3)가 부착된 텐숀아암(1)의 축(4)에 링크(2)를 연결하고 텐숀조절장치(B) 내벽보스(7b)에 토오션스프링(7)을 삽입하여 스프링 일단을 내벽의 스프링걸이(7a)에 고정하고 스프링 타단은 상기 내벽보스(7a)의 지지편(7c)에 축핀된 좌측관절아암(8)에 고정시킨다.The link (2) is connected to the shaft (4) of the tension arm (1) to which the guide roller (3) is attached to the inside of the set that allows the VTR cassette (A) to be mounted, and the tension adjusting device (B) inner wall boss (7b). Insert the torsion spring (7) to fix the spring end to the spring hanger (7a) of the inner wall and the other end of the spring fixed to the left joint arm (8) axially pinned to the support piece (7c) of the inner wall boss (7a) Let's do it.
또한 회동자재하게 연결된 상기 좌측관절아암(8)과 우측관절아암(8a)의 연결부분에는 인식폴(6)을 조립하여 상기 인식폴(6)이 스프링힘으로 텐숀조절장치(B)의 상측외부로 출몰되게 하며 우측관절아암(8a)의 단부에 고정된 가이드핀은 텐숀 조절장치의 측면에 형성한 안내홈(9)을 따라 유동할 수 있도록 하고 우측 관절아암의 가이드핀에 고정시킨 철선은 인장스프링(5)을 이용하여 텐숀아암의 링크(2)에 연결한 것이다.In addition, the recognition pole 6 is assembled to the connecting portion of the left joint arm 8 and the right joint arm 8a, which is connected freely, and the recognition pole 6 is a spring force on the upper outside of the tension adjusting device B. The guide pin fixed to the end of the right joint arm (8a) is allowed to flow along the guide groove (9) formed on the side of the tension adjusting device, and the iron wire fixed to the guide pin of the right articulated arm is tensioned. It is connected to the link (2) of the tension arm using the spring (5).
도면중 미설명부호 T는 테이프, 20은 안내로울러, 30은 안내핀이며, 11은 텐숀밴드, 10은 테이프인식홀이다.In the drawings, reference numeral T denotes a tape, 20 denotes a guide roller, 30 denotes a guide pin, 11 denotes a tension band, and 10 denotes a tape recognition hole.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
8mm용 VTR의 카세트테이프중 옵션에 따라 마찰계수가 작은 MP테이프에는 제2(b)도와 같이 인식홀이 막혀있고 마찰계수가 큰 ME테이프에는 인식홀이 뚫려 있으므로 이의 카세트테이프를 세트내에 끼워서 재생 또는 녹화할시에 마찰계수가 작은 MP테이트의 인식홀(10)이 텐숀조절장치(b0의 인식폴(6)을 눌러주게 되므로서 지지핀(4)으로 고정된 좌측관절아암(8)과 연결되어 있는 우측관절아암(8a)단부의 가이드핀이 텐숀조절장치 측벽의 슬라이더 안내홈(9)을 따라 제2(b)도와 같이 우측으로 이동하면서 철선 및 인장스프링(5)으로 연결된 링크(2)를 당기게 됨에 따라서 안내로울러(3)가 부착된 텐숀아암(1)을 좌측으로 작용하여 안내로울러(20)와 안내핀(30)으로 안내되는 테이프(T)에 텐숀을 주게된다.Recognition holes are blocked in MP tapes with a small coefficient of friction, depending on the options of 8mm VTR cassette tapes, and recognition holes are drilled in ME tapes with large coefficients of friction. When recording, the recognition hole 10 of the MP tape having a small friction coefficient is connected to the left joint arm 8 fixed by the support pin 4 by pressing the tension adjusting device (a recognition pole 6 of b0). The guide pin at the end of the right arm 8a is moved along the slider guide groove 9 on the side wall of the tension adjusting device to the right as shown in FIG. 2 (b) and connected to the link wire 2 and the wire 2 and the tension spring 5. As the pull is applied, the tension arm 1 to which the guide roller 3 is attached acts to the left to give tension to the tape T guided by the guide roller 20 and the guide pin 30.
이때 텐숀밴드는 텐숀아암을 완충시켜 준다.At this time, the tension band buffers the tension arm.
한편 상술한 MP테이프를 제거하고 ME테이프를 사용할 경우 사용중인 MP테이프를 제거하면 텐숀조절장치(B)의 인식폴(6)은 관절아암(8) 일단의 토오션스프링0에 의해 상승하면서 링크(8)와 연결된 우측관절아암(8a)의 가이드핀이 안내홈(9) 좌측으로 움직이게 되므로 당기고 있던 우측관절아암 단부의 철선과 인장스프링(5)을 놓아준다.On the other hand, if the above-mentioned MP tape is removed and the MP tape in use is removed, the recognition pole 6 of the tension adjusting device B is lifted by the torsion spring 0 of one end of the articulation arm 8 and the link ( Since the guide pin of the right joint arm (8a) connected to 8) is moved to the left of the guide groove (9), release the iron wire and the tension spring (5) at the end of the right joint arm.
따라서 제2(a)도와 같이 ME테이프를 사용할 경우 테이프인식홀(10)이 뚫어져 있기 때문에 인식폴(6)이 작용하지 않아 결국 텐숀아암을 당겨주지 않기 때문에 테이프는 텐숀아암만으로 테이프에 장력을 주게되는 것이다.Therefore, when using the ME tape as shown in FIG. 2 (a), the recognition pole 6 does not work because the tape recognition hole 10 is drilled so that the tape does not pull the tension arm. Will be.
이와같이 본 고안은 8mm용 VTR에 MP테이프와 ME테이프를 공용으로 사용할 수 있도록 테이프의 마찰계수에 따라 텐숀조절장치(B)에 의해 테이프의 백텐숀을 조절하도록 함으로서 헤드드럼 입구의 텐숀관리에 매우 효과적인 장점이 있는 것이다.In this way, the present invention is very effective for tension management of the head drum inlet by adjusting the back tension of the tape by the tension adjusting device (B) according to the coefficient of friction of the tape so that MP tape and ME tape can be used in common for the 8mm VTR. There is an advantage.
