い反射をさせる機構。[Scope of Claim for Utility Model Registration] A long groove passing through the center of rotation and perpendicular to the reflective surface is provided on the side plate of the reflective surface holding frame that stands perpendicular to the reflective surface, and the center of rotation is at the position of the reflective surface. Two links of the same length are attached to two axes equally spaced in the axial direction and the reflected optical axis direction, and the axle with the other ends of the links connected is inserted. As the angle between the projection optical axis and the reflected optical axis changes, the connecting axes of both links slide on the long groove, so that the long groove line always becomes the bisector of the angle between the two optical axes. , that is, the angular intersections between the projection optical axis and the reflecting surface and between the reflecting optical axis and the reflecting surface are equal, and a mechanism that allows correct reflection.
