    摘要： According to an embodiment of the invention, an image projection apparatus includes: a light source device; a first circuit board including an image display device configured to form an image using light, a connector, and an electrically conductive portion near the connector; a retaining member made of metal; an optical illuminating unit held by the retaining member and configured to guide the light to the image display device; an optical projecting unit configured to project the image onto a projection surface; a second circuit board configured to be electrically connected to the connector; a metal plate fixed and electrically connected to the retaining member; and an elastic metal member arranged on the metal plate. The first circuit board is fixed to the retaining member. The elastic metal member is in contact with the electrically conductive portion. The second circuit board is fixed and electrically connected to the metal plate.

    摘要： In a projector that includes a light source, an image forming unit, a projection optical unit, and a case to contain the light source, the image forming unit, the projection optical unit, and the power supply, takes outside air in through a first intake duct provided on the case, cools the power supply by circulating the taken outside air to the power supply circumventing the projection optical unit, and exhausts the air after cooling through an exhaust vent provided on the case. A second intake duct is provided nearby the power supply compared to the first intake duct, and the amount of outside air drawn into the case through the second intake duct is larger than the amount of outside air drawn into the case through the first intake duct.
