Abstract
A lens moving mechanism includes a guide section which supports a lens mount unit on which a lens for projecting light is mounted and guides the lens mount unit in three orthogonal axis directions including an optical axis direction of the light, and a base member which supports a saddle guide unit of the guide section and is fixed to a projector main body. The saddle guide unit includes first linear motion guide devices which are fixed to the base member and guide the lens mount unit in an orthogonal-to-optical axis direction orthogonal to the optical axis direction.
