본 고안은 8㎜용 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 to convert the tension of the VTR tape to adjust the back tension of the tape according to the coefficient of friction of the tape so that the MP tape (Metal Powder tape) or ME Evaporated tape used in 8mm VTR can be used in common. Relates to a device.
일반적으로 8㎜ VTR의 헤드드럼의 입구측에 테이프의 백텐숀을 관리하는 것이 중요하다.In general, it is important to manage the back tension of the tape on the inlet side of the head drum of 8 mm 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(20)와 안내핀(30)을 설치한 것에 있어서 안내로울러(3)와 부착된 텐숀아암(10의 축(4)에 링크(2)를 고착하고 안내핀(7)을 끼워붙임한 인식폴(6)을 표면에 캠홈(8)이 형성된 캠파이프(9)에 삽입하되 인식폴(6)의 안내핀 하부에 탄성스프링(10)을 개재시키고 고정나사구(9a)(9b)가 형성된 고정캠(11)을 캠파이프의 단차부에 회전가능하게 끼워 고정나사(10)로서 덱크(12)에 고정한다.In the case where the guide roller 20 and the guide pin 30 are provided inside the set that allows the VTR cassette A to be mounted, the link to the shaft 4 of the tension arm 10 attached to the guide roller 3 2) and inserting the recognition pole 6 to which the guide pin (7) is fitted into the cam pipe (9) with the cam groove (8) formed on the surface, but the elastic spring (10) below the guide pin of the recognition pole (6) ) And the fixing cam 11 having the fixing screw holes 9a and 9b are rotatably inserted in the stepped portion of the cam pipe and fixed to the deck 12 as the fixing screw 10.
또 상기와 같은 텐숀조절장치(B)의 캠파이프(9)에 철선(13)을 고정하고 상기 철선에 연결시킨 인장스프링(5)를 링크(2)에 연결한 것이다.In addition, the wire 13 is fixed to the cam pipe 9 of the tension control device B as described above, and the tension spring 5 connected to the wire is connected to the link 2.
미설명부호 T는 테이프, 15는 텐숀밴드이고 14는 테이프인식홀이다.Unexplained symbol T is tape, 15 is tension band and 14 is tape recognition hole.
이와같이 형성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention formed as described above are as follows.
8㎜용 VTR의 카세트테이프중 옵션에 따라 마찰계수가 작은 MP테이프의 인식홀이 막혀있고 마찰계수가 큰 ME테이프에는 인식홀(14)이 뚫려 있다.Recognition holes of MP tapes with small coefficients of friction are blocked in the cassette tapes of 8 mm VTRs, and recognition holes 14 are drilled in ME tapes with large coefficients of friction.
따라서 제3도(b)도와 같이 마찰계수가 작은 MP테이프를 장착하여 재생 또는 녹화할 경우 테이프 인식홀(14)이 막혀있기 때문에 테이프가 인식폴(6)을 눌러주게되어 인식폴에 부착된 안내핀(7)이 캠파이프(9)의 표면에 형성된 한쌍의 캠홈(8)을 따라서 하강하며 고정캡(11)에 회전가능하게 설치된 캠파이프(9)가 회전함으로써 상기 캠파이프(9)에 고작된 철선(13)과 인장스프링(5)을 당기게 된다.Therefore, the tape recognition hole 14 is blocked when the MP tape having a small coefficient of friction is mounted or played back as shown in FIG. 3 (b). Therefore, the tape presses the recognition pole 6 so that the tape is attached to the recognition pole. A pin 7 descends along a pair of cam grooves 8 formed on the surface of the cam pipe 9, and the cam pipe 9 rotatably installed on the fixed cap 11 rotates to the cam pipe 9. Pulled the wire 13 and the tension spring (5).
따라서 링크와동축상에 고착된 텐숀아암(1)을 동작시켜 안내로울러(20)와 안내핀(30)사이에 있는 테이프(T)에 텐숀을 주게된다.Therefore, the tension arm 1 fixed on the link and the shaft is operated to give tension to the tape T between the guide roller 20 and the guide pin 30.
이때 텐숀아암(1)을 완충시켜 줄 수 있도록 텐숀밴드(15)를 설치하였다.At this time, the tension band 15 was installed to buffer the tension arm 1.
한편 사용중인 MP테이프를 제거하면 텐숀조절장치의 인식폴(6)은 스프링(10)에 의해 상승한다.On the other hand, if the MP tape in use is removed, the recognition pole 6 of the tension adjusting device is lifted by the spring 10.
동시에 캠홈(8)에 끼워진 인식폴의 안내핀(7)이 슬라이드하면서 캠파이프(9)가 역회전하여 캠파이프의 철선이 제4도의 점선위치에서 원복되어 텐숀아암을 놓아주게 된다.At the same time, as the guide pin 7 of the recognition pole fitted to the cam groove 8 slides, the cam pipe 9 reversely rotates, and the wire of the cam pipe is restored at the dotted line in FIG. 4 to release the tension arm.
그리고 제3도(a)도와 같이 마찰계수가 큰 ME테이프는 인식홀(14)이 천공되어 있으므로 인식폴을 동작시키지 않아서 텐숀아암(1)을 구동시키지 못하기 때문에 안내로울러(20)와 안내핀(30)으로 테이프가 원상태로 안내될 수 있게된다.In addition, as shown in FIG. 3 (a), the ME tape having a high coefficient of friction does not drive the tension arm 1 because the recognition hole 14 is drilled and does not operate the recognition pole. At 30, the tape can be guided back.
이상과 같이 본 고안은 8㎜용 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.As described above, the present invention controls the tension of the head drum inlet by adjusting the back tension of the tape by the tension adjusting device (B) according to the friction coefficient of the tape so that the MP tape and the ME tape can be used in common for the 8 mm VTR. It has a very effective advantage.
