Description
Claims (1)
- (정정) 광원과 영상을 제공하는 액정소자와 이 액정소자에서 제공되는 영상을 확대 투영하는 프리즘 광학계를 포함하는 광학소자(10)와 ; 이 광학소자(10)에서 투사된 광의 경로를 확보하기 위한 전반사 미러(60)와 ; 이 전반사 미러(60)를 통하여 소정의 크기로 확대된 상이 투영되어 소정 크기의 화상을 제공하는 스크린(70)과 ; 상기한 부재들을 포함하도록 된 하우징(2)을 구비한 슬림형 배면 투사 프로젝터에 있어서 ; 상기 스크린(70)은 그 상부면이 상기 하우징(2)의 상면에 힌지 결합되고 그 하부면이 전후로 회동 가능하도록 결합 구비되어, 상기 광학소자(10)의 전원이 오프 상태인 경우 상기 하우징(2)의 앞면에 수직하게 위치되고, 상기 전원이 온 상태인 경우 그 하부가 상기 하우징(2)의 전면부로 회동 돌출되며, 상기 전반사 미러(70)는 상기 전원이 온 상태인 경우 상기 스크린(70)의 배치에 맞는 기울기를 갖도록 배치되어, 상기 하우징(2)의 앞뒤폭을 줄일 수 있도록 된 것을 특징으로 하는 슬림형 배면 투사 프로젝터.
