본 고안은 비데오 테이프 레코더에 있어서, 테이프 주행 또는 리와인드서치 즉, 이미지나간 장면을 찾기 위하여 테이프를 역주행시키는 작업시 테이프에 발생되는 진동을 방지하고 텐션밴드의 텐션을 조절하기위한 비데오 테이프레코더의 텐션조절장치에 관한 것이다.The present invention is a video tape recorder, the tape running or rewind search, that is, the video tape recorder to adjust the tension of the tension band to prevent the vibration generated in the tape during the operation to reverse the tape to find the image out of the scene Relates to a device.
종래의 텐션조절장치는 조절편에 장공과 볼트를 형성하고 이의 일단에 텐션밴드의 일단을 고정하고 텐션밴드의 타단은 텐션암에 고정하여서 되어 있으나, 이는 조절편을 일단 조절하면 이를 고정함으로서 텐션밴드의 일단은 움직이지 않고 고정된 상태에서 텐션암의 유동에 의해서만 테이프의 진동을 방지토록되어 있어 만족할만한 효과를 얻지 못하였으며 리와인드서치 작업시에는 텐션밴드가 완전히 서플라이릴을 해방시키지 못하고 서플라이 릴을 간섭하게되어 테이프의 진동이 오히려 많아지므로 화면이 선명치 못한 결점이 있었다.Conventional tension control device is to form a long hole and a bolt on the adjustment piece and fixed one end of the tension band and the other end of the tension band is fixed to the tension arm, which is fixed by adjusting the tension band once the adjustment piece At one end of the tape, the tape's vibration was prevented only by the tension arm's flow in the fixed state, and the satisfactory effect was not obtained. During the rewind search, the tension band did not completely release the supply reel and interfered with the supply reel. The vibration of the tape is rather increased, so the screen was not clear.
본 고안은 종래의 이러한 결점을 해결하기 위한 것으로 압압부를 가진 작동간과 유동편, 조절치차와 장공 및 볼트를 가진 스톱퍼를 구성하여 작동간과 스톱퍼의 사이에서 압압부에 의해 유동되는 유동편에 텐션밴드의 일단을 고정하여 되는 것으로 테이프의 주행시는 물론 리와인드서치때에도 서플라이릴이 텐션밴드의 간섭을 받지 않도 록한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the above-mentioned shortcomings, and constitutes a stopper having a pressurizing part and a moving piece, a control gear and a long hole, and a bolt, and a tension band on the moving piece flowing by the pressing part between the operation and the stopper. One end of the tape is fixed so that the supply reel does not receive the interference of the tension band during the rewind search as well as the driving of the tape. This will be described in detail with reference to the accompanying drawings.
즉, 솔레노이드(2)에 작동하는 가동편(3)에 선단에 요부(4')를 가진 작동편(4) 후단에 통공(4")을 형성하되 솔레노이드(2), 가동편(3), 통공(4")에 이르도록 핀(3')으로 핀설하고, 돌출부(5)에는 링크(6)(6')(6")를 연결하며 요부(4')의 전방에 걸림턱(7')을 가진 회동편(7)을 축(7")에 연설하여 걸림턱(7')과 작동편(4)의 사이에 스프링(8)을 탄설하고 회동편(7)의 일단에 링크(9)를 연결하며 링크(9)의 타단에 압압부(10')를 가진 작동간(10)을 축(11)에 축설하고 압압부(10')에 의해 유동토록 유동편(12)을 축(12')에 축설하되 유동편(12) 상면에 텐션밴드(15)의 일단을 고정하며 텐션밴드(15)의 타단은 괘지편(16')을 가진 텐션암(16)에 스프링(16')으로 기판(1) 하단에 탄성하고 유동편(12)의 하단에 조절치차(13'), 장공(13"), 조정볼트(13'") 및 걸림편(14)을 가진 스톱퍼(13)를 축(12')에 축설하며 통상의 기판(1)에 조절치차(13')의 전방으로 통공(17)을 천공하여서된 것으로 미설명부호 18은 서플라이릴, 19은 테이크업릴, 20은 아이들러, 21은 조정간이다.That is, a through hole 4 "is formed at the rear end of the operating piece 4 having the recessed portion 4 'on the movable piece 3 acting on the solenoid 2, but the solenoid 2, the movable piece 3, Pins 3 'to reach through holes 4 ", and links 6, 6' and 6" to protrusions 5 and locking jaws 7 'in front of recesses 4'. The rotating piece (7) on the shaft (7 ") to install the spring (8) between the engaging jaw (7 ') and the working piece (4) and to the link (9) at one end of the rotating piece (7). ), The operation section 10 having the pressing section 10 'at the other end of the link 9 is laid on the shaft 11, and the moving piece 12 is moved by the pressing section 10'. 12 ') and one end of the tension band 15 is fixed to the upper surface of the flow piece 12, and the other end of the tension band 15 is a spring 16' on the tension arm 16 having the hanging piece 16 '. The stopper 13 is elastic at the bottom of the substrate 1 and has an adjustment gear 13 ', a long hole 13 ", an adjustment bolt 13'" and a locking piece 14 at the bottom of the flow piece 12. On the shaft 12 ' In the conventional substrate 1, the through hole 17 is drilled in front of the adjustment gear 13 ', and reference numeral 18 denotes a supply reel, 19 a take-up reel, 20 an idler, and 21 an adjustment period.
이상과 같이 구성된 본 고안은 테이프가 정상적인 주행을 할때는 텐션암(16)이 테이프의 진동을 스프링(16")에 의하여 방지토록하고 리와인드 서치때는 별도의 버튼(도시생략)을 작동시키면 리와인드되면서 동시에 솔레노이드(2)가 작동하여 가동편(3)을 밀어주면 이와핀(3')으로 연동하는 작동편(4)이 링크(6)(6')(6")와 함께 작동하여 회동편(7)이 축(7")을 중심으로 화살표(a) 방향으로 회동토록하는 데 이에 따라 회동편(7)에 연결된 링크(9)가 화살표(b) 방향으로 작동하여 작동간(10)을 화살표(c) 방향으로 밀어주면 축(11)을 중심으로 작동간(10)이 회동하면서 이의 압압부(10')가 유동편(12)을 압압하고 있다가 해방시키면서 유동편(12)이 유동토록하며 서플라이 릴(18)을 간섭하던 텐션밴드(15)가 해방토록하며 테이프를 다시 정상주행시키면 상기의역으로 작동하면서 작동간(10)의 압압부(10')가 유동편(12)을 밀어 유동편(12)이 스톱퍼(13)의 걸림편(14)과 작동간(10)의 압압부(10') 사이에 고정토록하여 텐션밴드(15)가 서플라이릴(18)을 간섭토록 한 것이다.The present invention configured as described above allows the tension arm 16 to prevent the vibration of the tape by the spring 16 "when the tape is running normally, and rewinds the solenoid at the same time by operating a separate button (not shown) during the rewind search. (2) actuates and pushes the movable piece (3), the actuating piece (4) which interlocks with the tooth pin (3 ') acts together with the links (6) (6') (6 ") and the rotating piece (7) The shaft 9 is rotated about the axis 7 "in the direction of the arrow a so that the link 9 connected to the pivot piece 7 operates in the direction of the arrow b to move the operation 10 to the arrow c. In the direction of rotation), the operating section 10 rotates around the shaft 11, while the pressing section 10 'presses the flow piece 12 and releases it, causing the flow piece 12 to flow and supply When the tension band 15 that interfered with the reel 18 is released, and the tape runs normally again, The pressing section 10 'of the operating section 10 pushes the moving piece 12 so that the moving piece 12 is positioned between the engaging piece 14 of the stopper 13 and the pressing section 10' of the operating section 10. The tension band 15 interferes with the supply reel 18 so as to be fixed to the.
한편, 통공(17)에 별도의 조정간(21)을 삽입하여 조정간(21)의 치차로 스톱퍼(13)의 조절치차(13')에 치합한 후 볼트(13'")를 장공(13") 사이에서 풀려 조정간(21)으로 조절한후 다시 볼트(13'")를 조이도록하여 텐션밴드(15)의 간섭도를 조절토록한 것이다.On the other hand, a separate adjustment section 21 is inserted into the through hole 17 and engaged with the adjustment gear 13 'of the stopper 13 by the gear of the adjustment section 21, and then the bolt 13' "is inserted into the long hole 13". After loosening the gap between the adjustment period 21 and tighten the bolt 13 '"to adjust the interference band of the tension band 15.
이상과 같이 작동하는 본 고안은 구조가 간단하고 쉽게 조절할 수 있으며 리와인드 서치때 텐션밴드(15)가 서플라이릴(18)을 간섭하지 않으므로 테이프에 진동이 생기지 않아 화면이 선명한 잇점을 지닌 것이다.The present invention works as described above, the structure is simple and can be easily adjusted, and because the tension band 15 does not interfere with the supply reel 18 during the rewind search, the screen has a vivid advantage because the vibration does not occur on the tape.
