Title: LENS MOVING MECHANISM
Abstract:
This lens moving mechanism is equipped with a guide unit that supports a lens mount to which a lens for projecting light is mounted while guiding the lens mount in three orthogonal axis directions including the optical axis direction of the light, and a base member that supports a saddle guiding portion of the guide unit and is fixed to a projector body. The saddle guiding portion is equipped with first linear-motion guide devices that are fixed to the base member and guide the lens mount in a direction orthogonal to the optical axis, said direction perpendicularly intersecting the optical axis direction of the light.
