본 고안은 VTR의 데크내에 설치된 오디오 콘트롤(A/C) 헤드 위치 가변장치에 관한 것으로서, 헤드의 위치를 가변 조정하기 위하여 가이드 로라 포스트에 원판형 캠을 결합 설치하여 조작의 간편화 및 구성의 단순 간단화를 꾀하기 위하여 안출 제공된 것이다.The present invention relates to an audio control (A / C) head position variable device installed in the deck of the VTR, and to simplify the operation and simple configuration by combining a disc-shaped cam in the guide roller post to variably adjust the position of the head. It is provided for the purpose of anger.
종래의 모든 VTR 데크 메카니즘에서는 제4도에서와 같이 VTR 데크 메카니즘의 구성 요소 중에서 회전헤드와 A/C 헤드가 서로 상호간 일정 거리를 유지하기 위하여 A/C 헤드 위치를 조정하도록 되어 있는 바, A/C 헤드(5')의 위치를 적당한 위치로 조정하기 위해서는 조정렌지를 사용하여 콘스크류(21')의 상측홈(22') 부위를 잡고 돌려 줌으로서, 샤프트(23')에 나사 결합된 콘스크류(21')의 상하 수직운동에 의해 접하는 부위의 반경이 가변되는 만큼 A/C 헤드(5')를 장착한 브라켓트(2')가 샤프트(3')를 중심으로 회전하게 되어 A/C 헤드(5')의 위치 조정이 되도록 한 것이다.In all conventional VTR deck mechanisms, as shown in FIG. 4, among the components of the VTR deck mechanism, the rotation head and the A / C head are arranged to adjust the A / C head position to maintain a certain distance from each other. In order to adjust the position of the C head 5 'to an appropriate position, the cone is screwed to the shaft 23' by holding and turning the upper groove 22 'portion of the screw 21' using the adjusting wrench. The bracket 2 'with the A / C head 5' is rotated about the shaft 3 'as the radius of the contact portion is changed by the vertical movement of the screw 21'. The position of the head 5 'is adjusted.
즉, 콘스크류(21')는 역삼각형으로 되어 있으며, 브라켓트(2')가 비틀림 스프링(4')과 탄동 결합 설치되는 관계로 콘 스크류(21')의 외측표면에 브라켓트(2')의 돌기부(12')가 항상 접촉하도록 되어 있는 것으로 회전하려는 브라켓트(2')를 잡아주기 위해서는 콘 스크류(21')의 상단에 브라켓트(2')의 돌기부(12')가 닿도록 해야 한다.That is, the cone screw 21 'has an inverted triangle, and the bracket 2' is elastically coupled to the torsion spring 4 'so that the bracket 2' is attached to the outer surface of the cone screw 21 '. In order to hold the bracket 2 'to be rotated as the protrusion 12' is always in contact, the protrusion 12 'of the bracket 2' should come into contact with the top of the cone screw 21 '.
따라서, 샤프트(23')에 콘 스크류(21')를 나사식으로 결합 설치하여 콘 스크류(21')의 상단에 형성된 홈(22')에 조정렌치를 결합시키고 시계 방향으로 회전시켜 주면 콘 스크류(21')는 하방으로 회동하면서 이동한다. 그러므로 이동된 콘 스크류(21')의 상단에 브라켓트(2')의 돌기부(12')가 닿게 되어 브라켓트(2)의 회전을 제어하며, 반대로 조정할 경우 콘 스크류(21')를 반시계 방향으로 회전시켜 주면 콘 스크류(21')는 상방으로 이동하여 콘 스크류(21')의 하단이 돌기부(12')에 위치하게 되면서 브라켓트(2')는 역으로 회전하는 것이다.Therefore, when the cone screw 21 'is screwed into the shaft 23' and installed, the adjustment wrench is coupled to the groove 22 'formed at the top of the cone screw 21' and rotated in a clockwise direction. 21 'moves while rotating downward. Therefore, the projection 12 'of the bracket 2' comes into contact with the upper end of the moved cone screw 21 'to control the rotation of the bracket 2, and when adjusted in the opposite direction, the cone screw 21' is counterclockwise. When rotated, the cone screw 21 'is moved upward and the lower end of the cone screw 21' is positioned on the projection 12 ', while the bracket 2' is rotated in reverse.
즉, 콘 스크류(21')의 하단은 돌기부(12')에 닿지 않도록 직경을 적게 형성시켰던 것이다.That is, the lower end of the cone screw 21 'is formed to have a smaller diameter so as not to contact the protrusion 12'.
그리고, 콘스크류(21')를 회전시켜 주기 위해서는 샤프트(23')에 나사부를 길게 형성시켜 주지 않으면 콘 스크류(21')의 상하 이동의 높이가 맞지 않아 브라켓트(2')의 회전을 원하는 만큼 시킬 수가 없는 것이고, 또한 A/C 헤드의 위치 조정량이 많이 필요한 경우에는 콘 스크류(21')의 상하 이동 높이가 많아야 되므로 콘 스크류의 회전량이 많아지면서 조작 시간이 많이 소요되는 단점이 있었던 것이다.In order to rotate the screw 21 ', unless the screw portion is formed long in the shaft 23', the height of the up-and-down movement of the cone screw 21 'does not match so that the bracket 2' can be rotated as desired. If the amount of position adjustment of the A / C head is not necessary, the up and down moving height of the cone screw 21 'must be large, so that the amount of rotation of the cone screw increases and the operation time is increased.
본 고안은 종래의 결점을 없애고자 고안한 것으로 종래의 콘 스크류와 샤프트를 없애고 VTR 데크에 설치된 기존 가이드 로라 포스트에 캠을 설치하여 캠의 회동각을 적게 하여도 브라켓트의 위치 조정을 자유자재로 할 수 있는 것이다.The present invention was devised to eliminate the defects of the related art, and it is possible to freely adjust the position of the bracket even if the cam rotation angle is reduced by installing the cam on the existing guide roller post installed on the VTR deck, eliminating the conventional cone screw and shaft. It can be.
이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.
VTR 데크(1)에 브라켓트(2)를 축착한 샤프트(3)의 하단에 토션스프링(4)을 탄지시켜 브라켓트(2)에 고정 설치된 A/C 헤드(5)의 위치 조정을 한 것에 있어서, VTR 데크(1)에 가이드 로라(6)와 스프링(7)을 탄력 설치한 통상의 가이드 로라 포스트(8)의 하단부에 나사부(9)를 형성시켜 나사공(10)이 편심된 소정두께와 직경의 원판형 캠(11)을 나사식 설치한 것으로 미설명 부호 12는 돌기부, 13은 너트부이다.In the position adjustment of the A / C head 5 fixed to the bracket 2 by holding the torsion spring 4 at the lower end of the shaft 3 on which the bracket 2 is fixed to the VTR deck 1, Predetermined thickness and diameter in which the screw hole 10 is eccentric by forming the threaded portion 9 at the lower end of the conventional guide roller post 8 in which the guide roller 6 and the spring 7 are elastically installed on the VTR deck 1. The disc-shaped cam 11 of this embodiment is screw-mounted, and reference numeral 12 denotes a protrusion and 13 a nut portion.
이와 같이 구성된 본 고안은 A/C 헤드(5)의 위치를 고에하고자 할 경우에는 가이드 로라 포스트(3)에 나사식 설치된 원판형 캠(11)을 브라켓트(2)의 돌기부(12)에 닿도록 하면 되는 것으로 원판형 캠(11)이 편심되어 있기 때문에 가이드 로라 포스트(8)의 중심제서 거리가 먼 부분의 면에 돌기부(12)가 닿도록 하면 되는 것이다.When the A / C head 5 is positioned, the present invention configured as described above touches the projection 12 of the bracket 2 with the disc-shaped cam 11 screwed to the guide roller post 3. Since the disc-shaped cam 11 is eccentric, the projection part 12 should just touch the surface of the part in which the center removal distance of the guide roller post 8 is far.
즉, 가이드 로라 포스트(8)의 중심에서 거리가 가까운 곳에서 먼 곳까지의 거리가 다양하기 때문에 브라켓트(2)의 돌기부(12)만 접촉되어 회전하지 못하도록 하면 되는 것이다. 그리고, A/C 헤드(5)의 위치조정이 필요할 경우에 원판형 캠(11)을 회전시켜 돌기부(12)가 접촉되지 않도록 하면 되는 것으로 원판형 캠(11)의 나사공(10)과 포스트의 나사부(9)를 이용하여 회전시켜 가이드 로라 포스트(8)에서 거리가 가까운 부분을 돌기부(12)에 위치하도록 하면 브라켓트(2)는 자유자재로 회전을 하는 것이다.That is, since the distance from the near to the far distance from the center of the guide roller post 8 is varied, only the protrusions 12 of the bracket 2 may be in contact with each other to prevent rotation. When the position of the A / C head 5 needs to be adjusted, the disk cam 11 may be rotated so that the protrusion 12 does not come into contact with the screw hole 10 and the post of the disk cam 11. By rotating by using the threaded portion 9 of the guide roller post 8 so that the distance closer to the projection portion 12 is located in the projection portion 12 is to freely rotate the bracket (2).
이때, 원판형 캠(11)은 한바퀴 회전할 때 나사산이 한바퀴 회전할 때와 같으므로 원판형 캠(11)의 상하 이동의 높이가 많이 필요로 하지 않는 것이다. 그러므로, 원판형 캠(11)을 한바퀴 회전시켜 주지 않아도 브라켓트(2)의 돌기부(12)가 닿지 않게 되므로 A/C 헤드(5)의 위치 조정을 마음대로 많이 하든가 적게 하든가 관계가 없는 것이다.At this time, the disk cam 11 does not require much height of the vertical cam 11, because the screw thread is rotated one turn when rotated one round. Therefore, since the projection 12 of the bracket 2 does not touch even if the disc-shaped cam 11 is not rotated once, it is irrelevant whether the position adjustment of the A / C head 5 is arbitrarily made or reduced.
이와 같이 원판형 캠(11)의 상하 이동이 적은 범위내에서 브라켓트(2)의 회전을 하도록 함으로서 종래와 같은 콘 스크류의 상하 이동 범위가 상당히 크던 것은 현저히 작게 개선한 것이며, 또한 원판형 캠이 한바퀴를 회전하든지 하지 않든지 관계없이 본 고안의 목적을 충분히 달성할 수 있기 때문에 종래와 같이 콘 스크류의 회전량을 많이 필요로 하지 않으므로 조정 시간이 걸리지 않아 작업시간도 단축시킬 수가 있으며, 콘 스크류 및 조정용 샤프트를 삭제하여 기존 가이드 로라 포스트에 본 고안을 설치함으로서 원가절감에 일익을 담당함과 동시에 공정의 단순화를 도모할 수 있는 특출한 효과가 있는 것이다.In this way, the bracket 2 is rotated within the range in which the disc cam 11 is vertically moved so that the up and down movement range of the conventional cone screw is considerably small, and the disc cam is one round. It is possible to achieve the purpose of the present invention regardless of whether it rotates or not, so it does not require much amount of rotation of the cone screw as in the prior art, so it does not take adjustment time and can shorten the working time. By installing the present invention in the existing guide roller post by eliminating the shaft, it has an extraordinary effect that can play a role in cost reduction and at the same time simplify the process.
