PROBLEM TO BE SOLVED: To solve the problem wherein a projector 10 has a difficulty in downsizing the projector 10 and noise made by a fan, since a plurality of heat sources are incorporated in the projector 10 besides a light source lamp and a plurality of cooling fans are provided to cool the respective heat sources. SOLUTION: In the data projector 10, a light source device 61 is arranged near the air exhaust port 113 of the cooling fan, and is cooled by exhaust air from the cooling fan, and also the heat generation sources other than the light source device 61 in the projector 10 are cooled by outside air current sucked by the cooling fan.
