본 고안은 가정용 비디오테이프레코더, 디지탈 오디오 테이프 레코오더등의 테이프 주행계에 있어서, 테이프의 장력 변화를 효율적으로 제어하여 미소 장력 변화에 의한 화상의 흔들림이나 음성의 떨림을 방지하는 테이프텐숀 조절장치에 관한 것으로 특히, 임피던스로울러와 테이프텐션폴을 일체형으로 하여 두가지 기능을 동시에 수행하도록 한 자기기록 재생기기의 테이프 장력 조절장치에 관한 것이다.The present invention is a tape tension control device for controlling the tape tension change efficiently in a tape traveling system such as a home video tape recorder or a digital audio tape recorder to prevent image shake or voice shake caused by a micro tension change. In particular, the present invention relates to a tape tension adjusting device of a magnetic recording / reproducing apparatus which performs both functions simultaneously by integrating an impedance roller and a tape tension pole.
종래의 가정용 비디오테이프 레코더등은 첨부도면 제3도와 같이 테이프 주행계에 있어서 공급릴 및 테이크업릴 사이에 있는 테이프 안내 요소에 테이프가 접속하여 이송될 때 테이프에 항상 일정한 장력을 부여하기 위하여 테이프 텐숀 조절장치가 설치되어 있으며 또한 테이프가 그 길이 방향의 미소한 장력변화에 의한 진동으로 화상의 흔들림이나 음성의 떨림을 방지하기 위하여 임피던스로울러(9)를 테이프 주행경로상에 설치하였다.Conventional home videotape recorders and the like adjust the tape tension in order to always give a constant tension to the tape when the tape is connected and conveyed to the tape guide element between the feed reel and take-up reel in the tape traveling system as shown in FIG. An apparatus was installed, and an impedance roller 9 was installed on the tape running path in order to prevent the shaking of the image or the shaking of the voice due to the vibration caused by the slight tension change in the longitudinal direction.
따라서 테이프 텐숀 조절장치(3′)와 임피던스 로울러(9)가 별개로 설치되므로 제작 공정상 번거롭고 부품수 증가에 의한 코스트 상승 및 특히 임피던스 로울러(9)는 자기테이프(6)의 기록/재생면에 밀착되어 구동되므로서 자기기록신호에 악 영향을 주었다.Therefore, since the tape tension adjusting device 3 'and the impedance roller 9 are separately installed, it is cumbersome in the manufacturing process and the cost increase due to the increase in the number of parts, and especially the impedance roller 9 is applied to the recording / reproducing surface of the magnetic tape 6. As it is driven closely, it adversely affects the magnetic recording signal.
이와 같은 종래의 문제점을 해소하기 위하여 본 고안은 테이프 텐숀 조절장치와 임피던스 로울러를 일체로 조립하고 또한 테이프의 자기기록신호에 영향을 주지 않도록 테이프와의 접속부가 테이프의 기록/재생면의 반대쪽에 위치하도록 설치하여 기기의 성능을 높이고 제작 단가를 줄일수 있도록 함으로서 보다 양호한 기기를 제공하는데 그 목적이 있다.In order to solve such a conventional problem, the present invention assembles the tape tension adjusting device and the impedance roller integrally, and the connection with the tape is located on the opposite side of the recording / reproducing surface of the tape so as not to affect the magnetic recording signal of the tape. The purpose of the present invention is to provide a better device by improving the performance of the device and reducing the manufacturing cost.
이하 첨부된 도면에 따라 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1a도는 본 고안 테이프장력 조절장치의 부품 사시도로서 종래의 임피던스로울러와 텐숀폴이 일체로 구성된 것이다.Figure 1a is a perspective view of a part of the tape tension control device of the present invention is a conventional impedance roller and the tension pole is integrally configured.
상기 임피던스로울러의 후렌지(2a)는 직접 테이프와 접촉하지 않고 위로 연장된 테이프 접촉부(2b)에만 접촉하여 테이프 주행시 일체로된 임피던스로울러(2) 전체가 테이프를 따라 회전하면서 임피던스로울러(2)의 원통형 하단부 즉 후렌지(2a) 자체의 질량에 의한 관성력으로 프라이 휘일 기능을 하므로서 테이프 주행중 미세한 장력변화를 조절하게 된다.The flange 2a of the impedance roller does not directly contact the tape, but only the tape contact portion 2b extending upward, so that the entire integrated impedance roller 2 rotates along the tape while driving the tape, and the cylindrical shape of the impedance roller 2 By acting as a flywheel function by the inertia force of the lower end portion, that is, the flange 2a itself, the fine tension change during the tape running is controlled.
제1b도는 본 고안의 주요부의 측단면도로서, 임피던스로울러(2)의 형상을 알 수 있으며 상기 임피던스로울러(2)는 텐숀폴(3)에 의해 텐숀아암(1)에 고정되며 하단에는 자체중량에 의한 마찰을 줄이기 위해 트러스트베어링(4)이 있고 상단에는 와샤(3a)에 의해 텐숀폴(3)에서 이탈되지 않도록 하였다.Figure 1b is a side cross-sectional view of the main part of the present invention, the shape of the impedance roller (2) can be seen and the impedance roller (2) is fixed to the tension arm (1) by the tension pole (3) and the bottom at its own weight In order to reduce the friction caused by the thrust bearing (4) and the upper end was not to be separated from the tension pole (3) by the washer (3a).
제2도는 본 고안 테이프 장력 조절장치의 사용 상태 평면 구성도로서, 테이프가 로오딩된 상태를 나타낸 것이다.2 is a plan view showing the state of use of the tape tension control device of the present invention, showing the state in which the tape is loaded.
본 고안 테이프 장력 조절장치의 임피던스로울러(2)의 테이프 접속부(2b)가 테이프 접속부(2b)가 테이프(6)의 기록/재생 이면에 접촉하여 구동되도록 함을 나타내 주고 있다.The tape connecting portion 2b of the impedance roller 2 of the tape tension adjusting device of the present invention shows that the tape connecting portion 2b is driven in contact with the recording / reproducing back side of the tape 6.
또한 텐쇼아암(1)에 탄력을 주는 텐숀스프링(7) 및 테이프 공급리일(17)에 설치된 밴드브레이크(8)가 연결되어 있다.In addition, the tension spring 7 which gives elasticity to the tension arm 1 and the band brake 8 provided in the tape feed rail 17 are connected.
이와같이 구성된 본 고안은 테이프가 로오딩되어 구동중 공급리일(17)로 부터 나온 테이프의 장력이 변할 경우 텐숀스프링(7)의 탄성력과 밴드브레이크(8)의 제동력으로 저주파수의 비교적 큰 장력 변동을 스스로 조절할 수 있도록 하였고, 이보다 더 미세한 장력변동(고주파수의 변동)은 텐숀아암(1)에 설치된 임피던스로울러(2)의 관성에 의하여 조절할 수 있도록 하였다.According to the present invention, when the tape is loaded and the tension of the tape from the supply rail 17 changes during operation, the elastic force of the tension spring 7 and the braking force of the band brake 8 cause a relatively large tension fluctuation of the low frequency. Even finer tension fluctuations (high frequency fluctuations) can be controlled by the inertia of the impedance roller (2) installed on the tension arm (1).
따라서 본 고안은 종래의 텐숀폴(3′) 및 임피던스 로울러(9)의 역할을 동시에 수행하도록 하므로서 구조가 간단해져 작업공정 및 제작코스트를 낮출수 있으며 특히, 임피던스로울러(2)가 테이프의 기록/재생부의 이면에 접촉하도록 설치되므로 자기신호기록면의 손상, 마모, 이물질부착 등의 악 영향을 제거할 수 있으므로 양호한 화상 및 음성의 기록, 재생이 가능하도록한 유용한 고안이다.Therefore, the present invention allows the structure of the conventional tension pole 3 'and the impedance roller 9 to be performed at the same time, thereby simplifying the construction process and lowering the production cost. Since it is installed to be in contact with the rear surface of the reproducing section, it is possible to eliminate the adverse effects such as damage, abrasion, foreign matter adhesion, etc. of the magnetic signal recording surface, which is a useful design to enable recording and reproducing good images and audio.
