PROJECTOR

摘要

A projector includes an illumination unit which has an optical system including a light source apparatus, an image formation unit which has an optical system including a light modulator (liquid crystal panels), a projection unit which has an optical system including a projection lens, to which the image formation unit is coupled, and which is coupled to the illumination unit, and a base frame which fixes one of the illumination unit and the projection unit and holds the other shiftably in a direction parallel to a projection direction. In a case where the projection unit is fixed to the base frame, second fixing portions (projection unit fixing portions) of the projection unit are fixed, and first fixing portions (illumination unit fixing portions) of the illumination unit are shiftably held.

主权项

1. A projector in which light outputted from a light source apparatus is modulated by a light modulator in accordance with image information and the modulated light is projected through a projection lens onto a projection surface, the projector comprising:
an illumination unit which has an optical system including the light source apparatus; an image formation unit which has an optical system including the light modulator; a projection unit which has an optical system including the projection lens, to which the image formation unit is coupled, and which is coupled to the illumination unit; and a base frame which fixes one of the illumination unit and the projection unit and holds the other shiftably in a direction parallel to a projection direction.
