摘要： In a projection image displaying device which projects imaging light emitted from a projection lens by being reflected by a projection mirror, an air inlet for sucking external air is provided at the position of a sealing mechanism of the projection mirror. Air blown off through openings provided around the projection lens is sucked into a case through this air inlet. When a cooling operation of cooling components within the case is to be performed by sealing the projection mirror, a sucking operation through the air inlet is stopped. This prevents dust in the external air from adhering to a reflective surface of the projection mirror regardless of the installation state of the projection image displaying device.

摘要： In a projection image displaying device which projects imaging light emitted from a projection lens 2 by being reflected by a projection mirror 3, an air inlet 4d for sucking external air is provided at the position of a sealing mechanism 3a of the projection mirror 3. Air blown off through openings 2a, 2b provided around the projection lens 2 is sucked into a case through this air inlet 4d. When a cooling operation of cooling components within the case is to be performed by sealing the projection mirror 3, a sucking operation through the air inlet 4d is stopped. This prevents dust in the external air from adhering to a reflective surface of the projection mirror regardless of the installation state of the projection image displaying device.

摘要： An object of the invention is to reduce the size and weight of a video projector by shortening the length of the arm of a mirror rotator and reducing the size of a mirror. A video projector comprises a plurality of projection lenses through which image light rays from a liquid crystal panel are extracted in a magnified manner; a reflective mirror for reflecting the extracted image light rays onto a screen; and a mirror rotator for rotating the reflective mirror so that the extracted image light rays can be reflected in particular directions. Among the projection lenses, some of the projection lenses located farther away from the liquid crystal penal are partially cut such that areas through which the image light rays do not pass are cut off to create a lens cut-off space. The mirror rotator is placed in the lens cut-off space.

摘要： Provided is a projection video display device with which a sliding load is minimized while maintaining an adjustment precision in a lens shift mechanism. A lens shift mechanism (32) which moves a projection lens in a direction which is orthogonal to the optical axis of projected light has a configuration in which mobile bases (50, 60), which retain the projection lens, slide using a shaft (52), which is attached on a fixed member (4) side, as a guide member. A further aspect of the configuration is that a correction screw is inserted from the rear face side of the fixed member (4) to make contact with the shaft (52), and optical axis tilt and misalignment of the projection lens are corrected by adjusting the degree of insertion of the correction screw.
