Patent ID: 7296900

Claim:
A projector comprising: an optical system including: a light source that emits a light beam; a color beam splitting optical system that splits the light beam from the light source into sub-beams of predetermined colors; electro-optical devices that modulate the color beams split by the color beam splitting optical system in accordance with image information; a color beam combining optical system that combines the color sub-beams modulated by the electro-optical devices; and a projection lens that projects a resultant beam combined by the color beam combining optical system; an inner case to which optical components constituting the optical system are attached; vertically separable outer cases; and an enclosure which is constituted by the inner case and one of the outer cases; the inner case being fixed to said one of the outer cases so as to accommodate at least the color beam splitting optical system in the enclosure, wherein a resilient cushion member is provided between each optical component of at least the color beam splitting optical system and said one of the outer cases to which the inner case is fixed.
