Patent ID: 8052288

Claim:
A projector comprising: a light source device; an optical modulation device which modulates a luminous flux emitted from the light source device in accordance with image information, forming an image light; a projection optical device which magnifies and projects the image light; and an exterior casing which configures an exterior, wherein a luminous flux passage opening for allowing the image light projected magnified from the projection optical device to pass through is formed in a first surface of the exterior casing, the projection optical device includes an aspheric minor which reflects the image light to the first surface side, and magnifies and projects the image light via the luminous flux passage opening, the exterior casing is provided with: a transmissive member which closes the luminous flux passage opening, the transmissive member being disposed tilted upward from an image light projection side toward a side opposite to the projection side; and a cover which, being movably attached to the first surface, moves between a closed position in which the transmissive member is covered and an open position in which the transmissive member is exposed, a cover attachment portion to which the cover is attached is provided on the first surface the cover attachment portion includes: a bulging surface portion which protrudes above a region of the first surface other than the cover attachment portion; a tilted surface portion which, being tilted upward from the projection side toward the side opposite to the projection side, connects an end of the bulging surface portion on the image light projection side and the other region; and connection portions which, standing from ends of the bulging surface portion and tilted surface portion parallel to a direction in which the image light is projected, are connected to the other region, the luminous flux passage opening is formed in the tilted surface portion, and the cover, being movably attached to the connection portions, is positioned in the closed position by moving to the projection side, and positioned in the open position by moving to the side opposite to the projection side.
