摘要： A liquid crystal projector device of the present invention includes three image generating units for generating image light of three primary colors. Each image generating unit has a polarizing plate and an optical compensating plate held by a combination frame and placed on a support base. The combination frame includes a polarizing plate frame for holding the polarizing plate, and a compensating plate frame for holding the optical compensating plate. The polarizing plate frame is supported on the support base via a rotation adjustment mechanism for rotating the polarizing plate about the optical axis, while the compensating plate frame is supported on the polarizing plate frame via an inclination adjustment mechanism for inclining the optical compensating plate by rotating the optical compensating plate about two axes perpendicular to the optical axis and perpendicular to each other.

摘要： A projector device-of the present invention includes a light blocking mechanism for blocking leak light from a lamp unit. The light blocking mechanism includes a first light blocking member having a plurality of first light blocking plates arranged therein at certain pitches, and a second light blocking member having a plurality of second light blocking plates arranged therein at certain pitches. The first light blocking plates and the second light blocking plates each define a gap providing an air flow passage. A flat inclined part of each second light blocking plate extends in an inverted direction to a flat inclined part of each first light blocking plate, with a predetermined angle of inclination, so that the first light blocking plates and the second light blocking plates block the light emitted from the lamp unit toward a vent of a casing in all orientations.

摘要： A video projector includes a shell case, which accommodates optical components, and a cooling system, which directs ambient air toward the optical components. The cooling system includes a turbulent flow generator arranged in an intake duct. The turbulent flow generator includes a diagonal upstream surface that smoothly changes the direction of an air flow and generates a turbulent flow at the downstream side of the turbulent flow generator. Fine dust particles suspended in the turbulent flow adheres on a downstream surface of the turbulent flow generator and are removed from the air flow.

摘要： A projector including light valves respectively corresponding to red light, green light, and blue light. A color combining prism (e.g., cross dichroic prism) combines modulated light emitted from the light valves. A projection lens enlarges and projects the combined light from the color combining prism. An aberration correction lens corrects a chromatic aberration of magnification of the projection lens. A pressing member resiliently presses and fixes the aberration correction lens to the color combining prism at a light entrance surface for at least one of the red, green, and blue light.

摘要： An LCD projector including liquid crystal light valves, a duct, and nozzles. Each liquid crystal light valve includes optical components. Cooling air flows through the duct to cool the optical components of each liquid crystal light valve. The nozzles are arranged in correspondence with the liquid crystal light valves and blow the cooling air from the duct toward the optical components of the corresponding liquid crystal light valves. At least one nozzle includes an inlet, which is in communication with the duct, and an outlet, from which the cooling air from the inlet is blown out. The outlet has a width in a direction orthogonal to an optical axis of light that is set so that a blowing range of the cooling air is selected for each optical component in the corresponding liquid crystal light valve.
