Patent ID: 7213927

Claim:
A projector comprising: a light source apparatus to emit a substantially parallel illuminating light bundle to an illuminated area; a first lens array having a plurality of lenses to divide the illuminating light bundle emitted from the light source apparatus into a plurality of partial light bundles; a second lens array having a plurality of lenses corresponding to the plurality of lenses of the first lens array; a superimposing lens to superimpose the respective partial light bundles from the second lens array in the illuminated area; a color separating optical system to separate the light bundle from the superimposing lens into light bundles corresponding to a plurality of colored light; a plurality of electrooptic modulating apparatuses to modulate the light bundles separated by the color separating optical system in accordance with respective image information; a projecting optical system to project a light bundle modulated by the plurality of electrooptic modulating apparatuses; a shielding member in the vicinity of a light emitting surface or a light incident surface of the first lens array, in which a light transmitting area and a light non-transmitting area are alternately arranged in an optical path in a first direction vertical to an optical axis of illumination; and a scanning device provided between the superimposing lens and the color separating optical system, to scan an illuminating light bundle in an image forming area of the electrooptic modulating apparatus in the first direction synchronously with a screen writing frequency of the electrooptic modulating apparatus.
