摘要： In a projector (1) that includes a light source (61), an image forming unit (101), a projection optical unit (102), and a case (59) to contain the light source (61), the image forming unit (101), the projection optical unit (102), and the power supply (80), takes outside air in through a first intake duct (84) provided on the case (59), cools the power supply (80) by circulating the taken outside air to the power supply (80) circumventing the projection optical unit (102), and exhausts the air after cooling through an exhaust vent (85) provided on the case (59). A second intake duct (131) is provided nearby the power supply (80) compared to the first intake duct (84), and the amount of outside air drawn into the case (59) through the second intake duct (131) is larger than the amount of outside air drawn into the case (59) through the first intake duct (84).

摘要： An image projector (1) that air-cools an image generating device and a light source and can prevent dust from being adhered to optical devices in a projection optical unit is provided. The image projector (1) includes a projection optical unit (30, 40) that projects an image including a gap, and a case (59, 53) that contains the projection optical unit (30, 40). The case (59, 53) includes an exhaust vent (85) that is located on a predetermined surface of the case (59, 53) at a position facing a first fan (86), a first intake duct (92) provided on a surface of the case (59, 53) so as to face a second fan (91), and a second intake duct (84) provided on a surface different than the surface where the first intake duct (92) is provided. Air that flows from the first intake duct (92) toward the exhaust vent (85) is prevented from flowing in the gap, and air that flows from the second intake duct (84) toward the exhaust vent (85) flows in the gap.
