Projector apparatus

Abstract

To provide a highly-precise mechanism in a simple structure as a positional adjusting mechanism of a projector lens on a display device surface, and to provide a projector apparatus capable of manually moving the projector lens by means of an user interface unified into the focus and zoom adjusting mechanism, an outer surface of a lens guide portion is a surface of uneven shapes in which a plurality of protruded portions, each of whose vertical sections has an angle of inclination of 45° and an angle of apex of 90° with respect to a surface of a liquid crystal panel, and a plurality of recesses, each opposing thereto, are arranged at a constant pitch in a vertical direction. An inner surface of the lens guide portion has such a shape as to constitute a part of a cylinder of a tapered configuration such that an inner diameter becomes larger from an incident light side toward an outgoing light side. A lens holding portion is fixed to a projector body , and has a surface having plural uneven shapes, which are brought into tight contact with the the surface having plural uneven shapes of the lens guide portion. An outer periphery of a lens fixing portion is formed in a tapered configuration such that an outer diameter becomes larger from the incident light side toward the outgoing light side.
