본 고안은 픽쳐 써어치(picture search)의 경우 리일디스크의 회전속도를 제어하여 주기위한 비디오테이프레코오더의 리일디스크 제동장치에 대한 것이다.The present invention relates to a real disk braking apparatus of a video tape recorder for controlling the rotation speed of a real disk in the case of picture search.

통상적으로 픽쳐 써어치를 할 경우 리일에 의하여 하게 되어 있는데 이때에는 핀치로울러가 캡스턴으로부터 분리되어 리일의 회전력에 의해 테이프의 주행속도를 콘트롤하도록 되어 있었다. 그러나 종래에는 리일에 감겨있는 테이프의 양에 따라 주행속도가 달라지므로 픽쳐 써어치의 경우 화면이 좋지 못하게 되는 결점이 있었다.In general, when the picture search is performed by the rail, the pinch roller is separated from the capstan to control the running speed of the tape by the rotational force of the rail. However, in the related art, the driving speed varies depending on the amount of tape wound on the rail, and thus, the picture search has a disadvantage in that the screen is not good.

본 고안은 이와같은 점을 해결하기 위해 픽쳐 써어치를 할 경우 핀치로울러와 캡스턴이 접촉된 상태로 테이프를 일정속도로 주행시키는 과정에서 리일디스크를 정상주행에 맞도록 회전을 제어해주게 제동장치를 설치한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve this problem, the present invention installs a braking device to control the rotation of the real disc in the process of driving the tape at a constant speed with the pinch roller and capstan in contact with the picture search. When described in detail according to the accompanying drawings as follows.

캡스턴(7)에 착탈되는 핀치로울러(8)를 동작시켜주는 작동간(9)을 핀(6)으로 데크에 유착하여 핀(6')으로 유착된 전동간(10)의 선단부와 연동간(11)으로 연결하되, 전동간(10)의 선단부에 핀(6")으로 중간이 유착된 인장간(4)의 하단부를 접촉토록하고, (4)의 그상단부는 리일디스크(5)와 접촉되는 면에 펠트(2)가 부착되고 핀(6")으로 상단부를 유착한 브레이크(1)의 하단부와 스프링(3)으로 연결시켜서 된 것이다.An operation section 9 for operating the pinch roller 8 attached to or detached from the capstan 7 is attached to the deck with the pin 6 and interlocked with the tip of the transmission rail 10 adhered to the pin 6 '. 11), but the lower end of the tension bar (4) in which the middle is bonded with a pin (6 ") to the leading end of the rolling rail (10), the upper end of (4) in contact with the real disk (5) The felt 2 is attached to the surface to be connected, and the lower end of the brake 1, which is attached to the upper end with a pin 6 ", is connected with the spring 3.

미설명부호 “12”는 스토퍼이고 “13”은 아이들러(idler)이며 “14”는 리일구동용 샤프트이다.Unmarked “12” is a stopper, “13” is an idler and “14” is a real drive shaft.

이와같이 구성된 본 고안은 픽쳐 써어치의 경우에는, 제1(a)도와 같이 전동간(10)이 핀(6')을 중심으로 화살표방향(a)으로 이동되므로 이에 의해 연동간(11)이 당겨져 작동간(9)은 핀(6)을 중심으로 선단부가 화살표방향(b)으로 이동되어 핀치로울러(8)가 캡스턴 (7)에 접촉되어 이들 사이로 통과하는 테이프를 잡아주게 되며, 이 과정에서 전동간(10)의 선단부가 화살표방향(a) 이동될 때 핀(6")으로 유착된 인장간(4)의 하단부를 밀어주므로 그 상단부는 반대방향으로 이동되기 때문에 상단부에 착설된 스프링(3)이 브레이크(1)의 하단부를 당겨주게 되어 브레이크(1)는 핀(6")을 중심으로 회전되어 리일디스크(5)에 밀착되므로 펠트(2)의 마찰력에 의해 리일디스크(5)는 회전속도가 제어되는 것이다.According to the present invention configured as described above, in the case of the picture search, as shown in FIG. 1 (a), since the transmission shaft 10 is moved in the arrow direction a around the pin 6 ', the interlocking shaft 11 is pulled by this. In the operation section 9, the tip portion of the pin 6 is moved in the direction of the arrow b so that the pinch roller 8 contacts the capstan 7 to hold the tape passing therebetween. As the tip of the liver 10 pushes the lower end of the tension rod 4 adhered to the pin 6 "when the arrow direction a is moved, the upper end is moved in the opposite direction, so the spring 3 mounted on the upper end The lower end of the brake 1 is pulled out so that the brake 1 is rotated about the pin 6 " to be in close contact with the real disk 5, so that the real disk 5 is rotated by the frictional force of the felt 2 Is controlled.

이렇게 하여 리일디스크(5)의 회전속도가 제어되면 핀치로울러의 출구부의 테이프텐션이 입구부의 텐션보다 약해지므로 캡스턴의 회전콘트롤에 무리가 없게 되고 테이프의 주행이 데크에 평행된 상태로 정상주행이 되며 특히 리일디스크(5)에 감겨 있는 테이프의 양에 관계없이 주행속도가 일정하게 되어 화면이 좋게 되는 것이다. 또한 퍼워드(For word)나 리와인드(Rewind)시에는 제1(b)도와 같이 전동간(10)이 화살표방향(a')으로 이동되어 연동간(11)이 작동간(9)의 일부를 밀어주므로 작동간(9)선단부가 화살표방향(b')으로 이동되어 핀치로울러(8)는 캡스턴(7)에서 격리되고 동시에 전동간(10)의 선단부에 의해 밀려져 있던 인장간(4)의 하단부는 압압상태가 해제되므로 스프링(3)의 인장력으로 인장간 상단부가 스토퍼(12)측으로 당겨져 스토퍼(12)에 의해 과도하게 당겨지게됨이 방지되고, 또 스프링(3)에 의해 당겨져 리일디스크(5)에 밀착되어있던 브레이크(1) 역시 당겨졌던 힘에서 해제되므로 밀착상태가 이완되어 리일디스크(5)는 퍼워드나리와 인드시 테이프의 처짐이나 흔들림이 없을 정도의 힘만을 브레이크(1)로부터 받게 되는 상태로 회전이 제어되는 것이다.In this way, when the rotation speed of the real disk 5 is controlled, the tape tension of the outlet portion of the pinch roller becomes weaker than the tension of the inlet portion, so that the rotation control of the capstan is not overwhelming, and the running of the tape becomes normal in parallel with the deck. In particular, the running speed becomes constant regardless of the amount of tape wound on the real disk 5, so that the screen is good. In the case of a forward word or a rewind, the transmission rail 10 moves in the direction of the arrow a 'as shown in FIG. Since the front end of the operation section 9 is moved in the direction of the arrow b ', the pinch roller 8 is isolated from the capstan 7 and at the same time the tension section 4 pushed by the front end of the transmission section 10 is pushed. Since the lower end portion is released from the pressing state, the upper end portion between the tensions is prevented from being pulled excessively by the stopper 12 by the tension force of the spring 3, and pulled by the spring 3 5) The brake 1, which is in close contact with the brake 1, is also released from the pulled force, so that the close contact is relaxed, and the reel disk 5 has only a force such that there is no sagging or shaking of the tape during forwarding and leading. Rotation is controlled.

이와같이 작동되는 본 고안은 브레이크(1)의 작용에 의해 리일디스크에 감겨진 테이프의양에 관계없이 항상 테이프가 정상주행을 하게 되므로 픽쳐 써어치의 경우 화면상태가 매우 좋게 되는 효과적인 고안이다.The present invention operated as described above is an effective design in which the screen condition is very good in the case of picture search since the tape always runs normally regardless of the amount of tape wound on the real disk by the action of the brake 1.
