Patent ID: 7354161

Claim:
A projector, comprising: an optical modulator that forms an optical image by modulating a light beam irradiated by a light source in accordance with image information; a projection optical device that projects the optical image formed by the optical modulator in an enlarged manner; and a projection position adjuster that moves the projection optical device in a plane orthogonal to a projection direction and adjusts a projection position of the projection optical device, the projection position adjuster including: a fixing plate fixed inside the projector; a first moving plate that can move in a first axial direction and a second axial direction orthogonal to each other in a plane orthogonal to the projection direction; a first adjusting driver that moves the first moving plate in the first axial direction; a second moving plate that can move in the second axial direction and moves the first moving plate in the second axial direction by engaging with the first moving plate; and a second adjusting driver that moves the second moving plate in the second axial direction, wherein the first moving plate and the second moving plate are superposed onto the fixing plate in the projection direction or in a direction opposite to the projection direction, and the first moving plate is movably abutted on the fixing plate to support and fix the projection optical device.
