본 고안은 VTR이나 DAT같은 회전 헤드 기록 방식기기등에 있어서 소형 데크(DECK)에서 구동면적을 줄이고 한곳에 기계 구성을 집약할 수 있게된 핀치로울러 밀착 구동장치에 관한 것이다.The present invention relates to a pinch roller close driving device which can reduce the driving area in a small deck and concentrate the machine configuration in one place in a rotating head recording method such as a VTR or a DAT.

종래의 VTR이나 DAT같은 회전 헤드 기록 방식 기기등에 있어서는 핀치롤러가 캡스턴에 밀착시 안전한 주행과 감김을 위해 일정한 힘으로 밀착이 되도록 레버와 인장코일 스프링을 사용하였기 때문에 밀착 장치를 소형화 하기에는 적합하지 못할뿐만 아니라 장치가 한곳에 집약되어 있지 않으므로 변형에 약하며 밀착력이 떨어지던 결점이 있었다.In the conventional rotary head recording type devices such as VTR and DAT, the pinch roller is not suitable for miniaturizing the contact device because the lever and tension coil spring are used so that the pinch roller adheres with a constant force for safe driving and winding. However, because the device is not concentrated in one place, it was weak in deformation and had poor adhesion.

본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.The present invention has been devised to solve such a conventional drawback and the construction and operation effects by the accompanying drawings are as follows.

캡스턴 샤프트(1)가 고정된 본체(2)에 있어서 전면부로 고정된 드라이빙기어(3)와 맞물리어 회전될 수 있게 설치된 핀치기어(4)와 후부 끝단부에 지지편(5)이 돌출된 핀치아암(6)이 함께 샤프트(7)에 의해 본체(2)에 고정되어지며 그 사이에는 비틀림코일스프링(8)이 삽입되어지되 비틀림 코일스프링(8)의 일측 끝단부는 핀치기어(4)에 고정된 핀(9)면에 밀착되고 또 다른 일측 끝단부는 핀치아암(6)에 고정된 핀(9′)면에 밀착되고 또한 핀치아암(6)의 전면 끝단부에는 핀치로울러(10)가 삽입 고정되어서 구성되어진 것이다.In the main body 2 to which the capstan shaft 1 is fixed, the pinch gear 4 and the support piece 5 protruding from the rear end and the pinch gear 4 are installed so as to rotate in engagement with the driving gear 3 fixed to the front part. The arms 6 are fixed together to the main body 2 by the shaft 7 with a torsion coil spring 8 inserted therebetween, with one end of the torsion coil spring 8 fixed to the pinch gear 4. Close to the pin (9) surface and another one end is in close contact with the pin (9 ') surface fixed to the pinch arm (6) and pinch roller (10) is inserted into the front end of the pinch arm (6) It is composed.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

도면에 도시되지 않은 테이프 로딩모터에 의해 회전하는 드라이빙기어(3)를 통해 동력을 전달받아 핀치기어(4)가 시계방향으로 회전하여 캡스턴샤스프(1)에 핀치로울러(10)가 밀착이 되도록 구동하는데 이때 캡스턴샤프트(1)와 핀치로울러(10)가 밀착이 된 상태에서 일단 핀치기어(4)를 조금더 회전시키면 핀치기어(4)는 돌아가게 되고 또한 핀치로울러(10)는 멈추면서 밀착이 되므로 핀(9)(9′)의 사이가 벌어지면서 비틀림 코일스프링(8)에 의해 캡스턴에 일정한 힘을 가하게 되어 있어 밀착된 캡스턴샤프트(1)와 핀치로울러(10) 사이로 지나 지지편(5)에 밀착되면서 통과함과 동시에 헤드드럼에 감겨지는 테이프가 안전하게 주행하면서 감길 수 있게 되어진 것으로 본원은 종래의 레버방식에 비해서 밀착장치가 소형화 되었을뿐만 아니라 밀착장치가 한 곳에 집약되어 있으므로 변형에 강하며 밀착력이 좋게된 것이다.Power is transmitted through the driving gear 3 rotating by a tape loading motor not shown in the drawing so that the pinch gear 4 rotates clockwise so that the pinch roller 10 is in close contact with the capstan shaft 1. At this time, when the capstan shaft 1 and the pinch roller 10 are in close contact with each other, if the pinch gear 4 is rotated a little more, the pinch gear 4 is rotated and the pinch roller 10 stops and is in close contact Therefore, the pins 9 and 9 'are spaced apart and a constant force is applied to the capstan by the torsion coil spring 8, passing between the capstan shaft 1 and the pinch roller 10 that are in close contact with each other. The tape wound on the head drum is able to be wound while driving safely while being adhered to), and this company has not only miniaturized the contact device compared to the conventional lever method but also the contact device in one place. Because the drug is in the river, and modifications improve the adhesion.
