Patent ID: 8632191

Claim:
A projector, comprising: a light source; an electro-optic device which modulates light emitted from the light source; a projection lens having an optical axis and which projects the light modulated by the electro-optic device; and a lens shift mechanism which shifts the projection lens in a shift direction substantially perpendicular to the optical axis of the projection lens, the lens shift mechanism including: a shift unit which supports the projection lens and shifts the projection lens in the shift direction perpendicular to the optical axis, a guide unit which guides the shift of the shift unit, and a drive unit which moves the shift unit, the drive unit including: a rotation section as a rotated part which has a first bevel gear rotating around a center axis that extends in the same direction as the optical axis, and a transmission section which has a second bevel gear engaged with the first bevel gear and configured to transmit the rotation of the rotation section to the shift unit, the guide unit having a holding section which holds an end of the shift unit in such a manner that the shift unit can slide, and an inclined surface inclined to a plane parallel with the shift direction of the shift unit, the optical axis being provided either at the end of the shift unit or on the holding section of the guide unit.
