Abstract:
A projection direction change device includes a mirror that reflects light emitted from a projection lens unit of a projector, a mirror support part that rotatably supports the mirror around a first axis and a second axis, a first drive part that rotary drives the mirror around the first axis, and a second drive part that rotary drives the mirror around the second axis. An intersecting point of the first and second axes is positioned closer to the projection lens unit than a geometric barycenter of the mirror is.
