본 고안은 비디오 테이프 레코오더의 테이프가 이동할시에 발생하는 진동을 제어하기 위하여 녹음재생헤드와 오디오헤드 사이에 안내핀과 안내로울러를 설치하여 테이프가 원활하게 이동할 수 있도록 하였고 안내로울러 측면에 스프링이 탄지된 텐숀로울러를 설치하여 테이프의 이완 및 장력이 발생할 경우 텐숀로울러로서 탄발력을 조절하여 주므로서 항상 테이프를 팽팽하게 유지시켜 줄수 있도록 하여 테이프의 찌그러짐을 없애고 수명을 연장할 수 있게 함에 목적을 둔 테이프 텐숀 조절장치에 관한 것이다. 종래에는 테이프가 물림로울러와 모우터 축 사이에서 밀림되어 안내로울러에 안내되어 임피던스 로울러를 통과한 상태로서 이동되었으므로 임피던스 로울러가 일정한 지점에서 회전하면서 자체의 탄성력에 의하여 테이프의 진동옹을 제어하여 주었기 때문에 사용중에 테이프의이완 상태가 심할 경우에는 임피던스 로울러 자체의 탄성력으로는 테이프의 이완을 만족하게 제어하지 못하므로 화면이 찌그러지거나 테이프가 손상되어 수명이 짧았으며 기구적으로도 복잡하여 생산원가는 고가이면서도 고장이 잦아 신뢰성이 적었다.In order to control the vibration that occurs when the tape of the video tape recorder moves, a guide pin and guide roller are installed between the recording and playback head and the audio head so that the tape can move smoothly. When the tapered tension roller is installed and the tape is loosened and tensioned, the tension roller is used to adjust the elastic force so that the tape can be kept taut at all times, eliminating tape distortion and extending the life. It relates to a tape tension adjusting device. In the related art, since the tape was pushed between the roller and the motor shaft and guided to the guide roller and moved through the impedance roller, the tape was rotated at a fixed point, and thus the vibration of the tape was controlled by its elastic force. If the tape is severely relaxed during use, the elasticity of the impedance roller itself does not control the tape's relaxation satisfactorily, so the screen is distorted or the tape is damaged, resulting in shorter lifespan and mechanical complexity. Frequent breakdowns made it less reliable.
본 고안은 종래의 결점을 적게하고 신뢰도를 높이면서 생산원가를 절감할 수 있게 하기 위하여 샤시에 고정하는 폴베이스 상부에 안내핀이 고정되고 비틀림스프링을 탄지시킨 텐숀로울러와 안내로울러를 간단한 하나의 군이 되게 연설하되 임피던스 로울러의 위치에 텐숀로울러를 대체시켜 텐숀로울러에 탄지되어 있는 비틀림스프링의 탄발력으로 테이프의 이완상태를 항상 팽팽하게 유지할 수 있도록 구성한 것으로서 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is a simple group of tension rollers and guide rollers in which guide pins are fixed on the pole base fixed to the chassis and the torsion springs are held in order to reduce production defects and reduce production costs while increasing reliability. To make this speech, the tension roller is replaced at the position of the impedance roller, and the elastic force of the torsion spring held on the tension roller is maintained so that the state of relaxation of the tape can be maintained at all times. .
테이프(20)가 신호소거헤드(2)와 녹음재생헤드(1) 오디오헤드(3) 및 안내핀(8)에 안내되어 비디오 카셋트(4)에 권취되어 이동되게 한 것에 있어서 녹음재생헤드(1)와 오디오헤드(3) 사이의 샤시에 폴 베이스(10)를 고착하고 상부에 안내핀(5)을 유설하여 텐숀로울러(7)가 일축에 유설된 지지대(11)를 끼워붙임하고 비틀림스프링(12)을 안내핀(5)의 지지대와 텐숀로울러지지대(11)에 탄지시켜 안내로울러(6)를 풀베이스(10) 상부에 유설하여 하나의 군이 형성되게 한 것이다.The tape 20 is guided to the signal erasing head 2, the recording and playback head 1, the audio head 3 and the guide pin 8, and wound around the video cassette 4 so as to be moved. The pole base 10 is fixed to the chassis between the audio head 3 and the audio guide 3, and the guide pin 5 is installed on the upper portion, and the support roller 11 is attached to the shaft 11 and the torsion spring is mounted. 12) the support pin of the guide pin (5) and the tension roller support (11) by guiding the roller (6) on the top of the pull base (10) to form a group.
이와 같이 본 고안의 작용효과를 설명하면 테이프(20)가 녹음재생테이프 및 오디오테이프를 지날때 안내핀(5)과 안내로울러(6)로서 테이프(20)를 원활하게 이동할 수 있도록 안내를 하며 테이프(20)에 이완 및 장력이 발생할 경우에 텐숀로울러(7)에서 비틀림스프링(12)의 탄발력에 위하여 텐숀로울러(7)가 도면 제1도의 점선과 실선 방향으로 이동하면서 테이프(20)의 이완 및 장력을 제거하여 주게 되는 것이다.As described above, the effect of the present invention is to guide the tape 20 to smoothly move the tape 20 as the guide pin 5 and the guide roller 6 when the tape 20 passes the recording playback tape and the audio tape. When the tension and tension occurs in the 20, the tension roller 7 moves in the direction of the dashed line and the solid line in FIG. 1 for the elasticity of the torsion spring 12 in the tension roller 7 And to remove the tension.
이러한 본 고안은 녹음재생헤드와 오디오헤드사이에 테이프의 이완 및 장력에 따라 텐숀로울러가 위치를 이동하면서 테이프의 주행을 고르게 하여 주므로 테이프의 이동이 원활하여 화면이 찌그러지거나 테이프의 손상을 방지하여 테이프 수명을 연장하므로서 신뢰성이 높은 것이며 안내핀과 안내로울러 및 텐숀로울러가 풀 베이스 상부에 하나의 군으로 연설되어 있으므로 조립 설치가 간편하여 생산 원가를 절감할 수 있으며 신뢰도를 높일 수 있는 매우 실용적인 잇점이 있는 것이다.The present invention makes the tape run smoothly while the tension roller moves the position according to the tape relaxation and tension between the recording and playback head and the audio head, so that the tape is smooth and the screen is not crushed or the tape is damaged. It has high reliability by extending its lifespan, and the guide pins, guide rollers and tension rollers are addressed as a group on the top of the full base, which simplifies assembly and installation, which can reduce production costs and has a very practical advantage of increasing reliability. will be.
