Abstract
A projector includes a wireless device performing a predetermined function, an external housing which accommodates a light modulation device, a first controller, and the wireless device, an intake fan which introduces air outside the external housing into the external housing through an inlet port, an exhaust fan which discharges the air introduced into the external housing through the inlet port to the outside through an outlet port, a first channel which guides the air introduced through the inlet port toward the light modulation device by the drive of the intake fan, and a second channel which guides the air introduced into the external housing toward the exhaust fan via the wireless device by the drive of the exhaust fan.
