Abstract

본 발명은 광로 조절 장치의 구조를 안정하게 하기에 적합한 투사형 화상 표시 장치의 광로 조절 장치 구조에 관한 것으로, 종래에는 지지부가 거울 하부의 일측면에만 형성되어 있으므로 구조적으로 불안정하게 되는 결점이 있었으나, 본 발명에서는 거울(17) 양측 하부에 상부 지지부(16)를 각각 형성하므로써 거울 (17)을 구조적으로 안정하게 하고 거울(17)의 중앙 하부에도 상부 지지부(16)가 형성되어 구동시, 위로 들려지므로써 그 거울(17)을 일측에서 경사지게 할 때 보다 약 2배의 경사각을 얻을 수 있으므로 틸팅을 효율적으로 할 수 있는 효과가 있다.The present invention relates to an optical path adjusting device structure of a projection type image display device suitable for stabilizing the structure of the optical path adjusting device. In the related art, since the support part is formed only on one side of the lower part of the mirror, there is a drawback that is structurally unstable. In the present invention, the upper support portions 16 are formed at both lower sides of the mirror 17, thereby structurally stabilizing the mirror 17, and the upper support portions 16 are also formed at the center lower portion of the mirror 17 so that they are lifted up when driven. When the mirror 17 is inclined from one side, an inclination angle of about twice can be obtained, so that the tilting can be efficiently performed.
