본 고안은 VTR의 테이프 주행계에 사용되는 임피던스 로울러에 관한 것으로서, 특히 테이프의 주행시 진동을 억제할수 있도록 개량한 것이다.The present invention relates to an impedance roller used in a tape running system of a VTR, and is particularly improved to suppress vibrations when the tape runs.
임피던스 로울러는 테이프가 주행하는 과정에서 테이프가 진행방향 또는 수직방향으로 진동하는 현상을 자체 관성 질량에 의해 진동을 억압하는 역할을 수행하게 되며 따라서 임피던스 로울러는 정확한 회전을 요구하게 된다.Impedance rollers suppress the vibration by the inertial mass of the phenomenon that the tape vibrates in the advancing or vertical direction while the tape is running, and therefore the impedance roller requires exact rotation.
이러한 작용을 하는 임피던스 로울러를 종래에는 제1도와 같은 구조로 이루어져 있다. 즉 고정대(11)상에 설치된 축(12)에 외주면에 고무 로울러(13)를 씌운 로울러 홀더(14)를 장착하여 이탈되지 못하도록 E링(15)을 고정하여 사용하였다.Impedance rollers having such a function conventionally have a structure as shown in FIG. That is, the E-ring 15 was used to fix the roller holder 14 having the rubber roller 13 on the outer circumferential surface of the shaft 12 installed on the holder 11 so as not to be detached.
그러나 이러한 종래의 임피던스 로울러는 축(12)과 로울러 홀더(14)의 중앙축공과의 마찰력이 크므로 마찰저항이 커져 고무로울러(13)의 회전에 저항을 받게되며 또한 고정대(11)와 로울러 홀더(14)사이의 접촉면에서 마찰이 발생하게 될뿐아니라 접촉면이 고르지 못할 경우 로울러 자체의 진동을 유발하게 되어 지터(Jitter)로 나타내게 되고 이 지터성분은 화질에 영향을 미치게 되는 문제점이 있었다.However, since the conventional impedance roller has a large friction force between the shaft 12 and the central shaft hole of the roller holder 14, the frictional resistance is increased, thereby resisting the rotation of the rubber roller 13, and also the holder 11 and the roller holder. In addition to the friction between the contact surface (14) as well as the uneven contact surface caused the vibration of the roller itself is represented as jitter (jitter), there was a problem that this jitter component affects the image quality.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로서 축과 로울러간의 마찰면을 출여 마찰저항을 적게 하므로서 로울러가 원활하게 회전할 수 있도록하며, 축의 상면을 구형으로하여 로울러의 캡과 당접되어 회전시키므로서 로울러의 하중을 점접촉으로 지지토록하여 저항을 줄일 수 있도록 하여 임피던스 로울러가 진동없이 회전토록하여 테이프의 주행을 안정하게 하여 지터성분을 제거하여 항상 선명한 화질을 얻을 수 있도록 함에 본 고안의 목적이 있다.The present invention has been made to solve the above problems, the friction surface between the shaft and the roller to reduce the frictional resistance, so that the roller can be rotated smoothly, the upper surface of the shaft is in contact with the roller cap to rotate The purpose of the present invention is to allow the load of the roller to be supported by point contact so that the resistance can be reduced, and the impedance roller rotates without vibration, so that the running of the tape can be stabilized and the jitter component can be removed to always obtain clear image quality. There is this.
상기 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 구성 및 작용효과를 상세히 설명하면 다음과 같다.Embodiments for achieving the above object will be described in detail with reference to the configuration and the effect according to the accompanying drawings.
우선 본 고안의 구성을 제2도를 참조하여 설명하면 고정대(1)상에 수직으로 설치되는 축(2)의 상단은 구면(3)으로 형성하고 상기 축(2)에, 상면에 캡(4)이 씌워지고 중단에 칼라(5a, 5b)로 지지되는 고무로울러(6)을 장착한후, 상기 고정대(1)에 일측이 고정된 Z형 브라켓(7)의 타측하단에 설치된 돌기부(8)를 상기 로울러(6)의 캡(4)상부에 당접되도록 하여 고무로울러(6)의 이탈을 방지할 수 있도록 한것으로서 도면중 미설명부호 10은 브라켓(7)고정용 볼트이다.First, the configuration of the present invention will be described with reference to FIG. 2. The upper end of the shaft 2 installed vertically on the fixing stand 1 is formed as a spherical surface 3, and the cap 4 is disposed on the upper surface of the shaft 2. After mounting the rubber roller (6) is covered with the collar (5a, 5b) in the middle of the suspension, the projection (8) installed at the other lower end of the Z-shaped bracket (7), one side of which is fixed to the fixing (1) By contacting the upper portion of the cap 4 of the roller (6) to prevent the separation of the rubber roller (6), reference numeral 10 in the drawing is a fixing bolt for the bracket (7).
이와 같이 구성된 본 고안의 작용효과는 VTR에 테이프의 주행계에서 테이프가 주행할시 테이프와 접속되어 회전하게 되는 고무로울러(6)가 고정대(1)와 이격된 상태에서 칼라(5a, 5b)에 지지되는 축(2)에서 회전하므로 마찰면을 최소화 할수 있으므로 마찰저항을 줄일 수 있으며 회전변동을 감소하여 테이프 진행방향으로는 진동을 효과적으로 억압할 수 있다. 또한 로울러는 축(2)의 상단을 구면(3)으로 형성되어 있어 캡(4)의 하측면을 받힌 상태에서 고무로울러(6)가 회전하므로 캡(4)과 축(2)이 일점으로 점 접촉한 상태이므로 로울러가 회전하는데 저항없이 완전히 회전을 할 수 있어, 축방향에 대한 자체진동을 거의 발생하지 않게되며 캡(4)의 상면을 브라켓(7)의 끝단에 설치된 돌기부(8)가 당접된 상태이므로 고무로울러(6)의 고무로울러(6)의 이탈을 방지할수 있게 된다.The operation and effect of the present invention configured as described above are applied to the collars 5a and 5b in a state in which the rubber roller 6, which is connected to the tape and rotates when the tape travels in the traveling system of the tape to the VTR, is spaced apart from the fixing table 1. Since it rotates on the supported shaft (2), the friction surface can be minimized, thereby reducing the frictional resistance and reducing the rotational fluctuation, thereby effectively suppressing the vibration in the tape traveling direction. In addition, the roller is formed with a spherical surface 3 of the upper end of the shaft (2), the rubber roller (6) is rotated in the state receiving the lower side of the cap (4), so that the cap (4) and the shaft (2) is one point Since the roller is in contact with the roller, the roller can rotate completely without resistance, and almost no self-vibration occurs in the axial direction, and the protrusion 8 provided at the end of the bracket 7 contacts the upper surface of the cap 4. Since it is in a state where it is possible to prevent the separation of the rubber roller (6) of the rubber roller (6).
상기한 바와 같은 본 고안에 의하면 간단한 구성으로 테이프 주행시 발생하는 진동을 효과적으로 방지하여 지터성분의 발생을 방지하여 항상 선명한 화질을 얻을수 있게 된다.According to the present invention as described above, by virtue of the simple configuration, it is possible to effectively prevent the vibration generated when running the tape, thereby preventing the occurrence of jitter components, thereby always obtaining a clear picture quality.
