    摘要： An image projection apparatus includes: an image forming unit that forms an image using light from a light source; a projecting optical unit that forms a projected image of the image formed by the image forming unit; and an outer housing that houses the image forming unit and the projecting optical unit. The image forming unit and the projecting optical unit are provided in an order from a setting surface of the outer housing. A width of the outer housing in a direction perpendicular to a projection surface is larger at a position where the projecting optical unit is provided than at a position where the image forming unit is provided.

    摘要： An image projection apparatus includes a light source; an intake port to take in low-temperature air into the image projection apparatus; an exhaust port to exhaust air from the image projection apparatus; a ventilation unit to generate an air flow from the intake port to the exhaust port; a first flow path for hot-air exhaust having increased its temperature by taking heat from the light source; a second flow path for a part of the low-temperature air, taken from the intake port; and a mixing unit to mix the hot-air exhaust flowing from the first flow path and the low-temperature air flowing from the second flow path. The air mixed and exhausted from the mixing unit converges with another part of the low-temperature air, flowing from a third flow path set outside the mixing unit, at a space between the mixing unit and the exhaust port.
