PROJECTION DIRECTION SWITCHING DEVICE AND IMAGE PROJECTION APPARATUS

摘要

　The purpose of the present invention is to provide a projection direction switching device allowing easy switching between various directions of a projection light emitted from a projection device, and an image projection apparatus equipped with said a projection direction switch.　The image projection apparatus (10) has a projection device (20) capable of emitting a projection light in the direction of a predetermined axis line (L) through a projection lens (24), and a projection direction switching device (50) capable of switching the direction of the projection light emitted from the projection device (20). The projection direction switching device (50) is provided with: a mirror (54) reflecting the incident projection light from the projection device (20); and a position adjusting device (56) capable of rotating the mirror (54) around the axis line (L) and of tilting the mirror (54) in a direction that crosses the axis line (L).
