Abstract
본 발명은 캠코더용 뷰파인더의 렌즈초점. 조정장치에 관한 것으로, 렌즈초점의 미세조정과 렌즈의 소세작업이 용이하도록 한 것이다.The present invention is focused on the lens of the camcorder viewfinder. The present invention relates to an adjustment device, which facilitates fine adjustment of lens focus and cleaning of the lens.
본 발명은 초점조정노브의 내주면과 렌즈가 장착된 렌즈홀더의 외주면 각각에 암나사부와 수나사부를 형성하여 이들 두 구성부재를 나사결합함으로써 초점조정노브의 회전각에 대한 렌즈의 상대적인 이송거리가 적게 변화하도록 구성하는 한편 렌즈홀더 초점조정노브의 조작에 의해 렌즈홀더의 일측에 장착된 렌즈가 뷰파인더 본체의 외측으로 노출될 수 있도록 구성하여 뷰파인더의 렌즈의 정밀한 초점조정과 렌즈의 소세작업이 용이하게 이루어지도록 한 이점이 있다.According to the present invention, the inner and outer peripheral surfaces of the focusing knob and the lens holder on which the lens is mounted are formed with a female thread and a male thread, respectively. The lens mounted on one side of the lens holder can be exposed to the outside of the viewfinder main body by operating the lens holder focusing knob, which facilitates precise focusing and lens cleaning of the viewfinder lens. There is an advantage to this.
