Abstract

본 발명은 광학 뷰파인더를 이용한 캠코더에 관한 것으로, 특히 사진 촬영시 촬상소자에 전송되는 영상신호의 중단없이 뷰파인더를 통해 사용자가 피사체를 육안으로 확인할 수 있도록 하는 광학 뷰파인더를 이용한 캠코더에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camcorder using an optical viewfinder, and more particularly, to a camcorder using an optical viewfinder that allows a user to visually check a subject through a viewfinder without interruption of an image signal transmitted to an image pickup device. .

이를 위하여 피사체의 영상을 다수의 광학소자로 구성된 렌즈어셈블리를 통해 촬상소자와 필름 및 뷰파인더로 조사토록 이루어진 캠코더에 있어서, 상기 렌즈어셈블리와 필름 사이에 설치되어 입사되는 피사체의 영상을 소정비율로 반사 및 투과하는 빔 스플리트, 상기 빔 스플리트의 상측에 소정 간격을 두고 설치되어 피사체의 영상을 전향 투과하는 릴레이렌즈, 상기 릴레이렌즈의 상측에 소정간격을 두고 설치되어 피사체의 영상을 전량 반사하는 고정반사미러, 상기 고정반사미러의 일측에 소정간격을 두고 설치되어 피사체의 영상이 결상되도록 하는 결상렌즈, 상기 결상렌즈와 필름 사이에 설치되어 사진촬영 유무에 따라 상하측으로 이동되어 필름에 조사되는 피사체의 영상을 조사 및 차단되도록 하는 회전반사미러, 상기 회전반사미러의 상측에 소정간격을 두고 설치되어 입사되는 피사체의 영상을 전량 반사하는 반사프리즘, 상기 반사프리즘의 일측에 소정간격을 두고 설치되어 피사체의 영상을 직선성으로 유지하여 뷰파인더로 전송하는 콜리메이트렌즈로 이루어진 것이다.To this end, in a camcorder configured to irradiate an image of a subject to an image pickup device, a film, and a viewfinder through a lens assembly composed of a plurality of optical elements, the image of a subject installed between the lens assembly and the film is reflected at a predetermined ratio. And a beam split to transmit, a relay lens installed at predetermined intervals on the upper side of the beam split, and forwardly transmitting the image of the subject, and a fixed interval installed on the upper side of the relay lens to reflect the entire image of the subject. The reflection mirror, an imaging lens installed at one side of the fixed reflection mirror with a predetermined interval to form an image of the subject, and installed between the imaging lens and the film and moved up and down depending on whether or not to take a photograph of the subject to be irradiated on the film. Rotating reflection mirror to irradiate and block the image, the image of the rotating reflection mirror A reflective prism installed at a predetermined interval on the reflective prism that reflects the entire incident image, and a collimated lens installed at a predetermined interval on one side of the reflective prism to maintain the image of the subject in a linear manner and to transmit it to the viewfinder. will be.
