Abstract
A projector apparatus that can effectively reduce bending of a base plate supporting a lens shifting unit thereon and facilitates replacement of unit parts in the event of a failure is provided. The projector apparatus includes: a base plate attached inside a projector body; a lens supporting unit attached to the base plate and supporting a projection lens so as to be movable relative to the base plate; guiding mechanisms for guiding the lens supporting unit so as to be freely movable in a horizontal direction and a normal direction relative to the base plate; and fixing devices which fix the base plate to the projector body. The fixing devices include a plurality of first fixing devices provided at a peripheral edge of the base plate, and second fixing devices provided on an inner side of the plurality of first fixing devices.
