Abstract

본 발명은 투사형 화상표시장치의 광로조절수단에 관한 것으로서, 경질금속으로 이루어지며 외팔보를 갖는 지지대를 이 외판보의 소정위치의 하부가 액츄에이터의 상부와 부착되도록 기판상에 고정시켜 이 외팔보의 끝단에 부착된 구동전달부 하브의 변위량을 변위부의 변위량보다 크도록 하여 반상겨의 경사각을 크게 한다. 따라서, 다층 세락믹을 사용하지 않고 구조가 간단하므로 제조가 쉬우며, 또한 지지부에 의해 액츄에 이터의 변위량을 증폭하므로 반사경이 경사각을 증가시킬 수 있다.The present invention relates to an optical path adjusting means of a projection-type image display device, comprising a support made of hard metal and having a cantilever beam fixed to a substrate such that a lower portion of a predetermined position of the outer plate beam is attached to an upper portion of an actuator at the end of the cantilever beam. The inclination angle of the half bran is increased by making the displacement amount of the attached drive transmission part hub larger than the displacement amount of the displacement part. Therefore, since the structure is simple without using the multilayer ceramic, it is easy to manufacture, and since the displacement amount of the actuator is amplified by the support, the reflector can increase the inclination angle.
