摘要 |
<p>In a projector, a projection unit includes a projection mechanism that projects an image and an air hole that takes in or exhausts air used to dissipate heat generated from a light source included in the projection mechanism. A housing covers the air hole when the projection unit is in a storage position in which the projection unit does not project an image and uncovers the air hole when the projection unit is in a projection position in which the projection unit projects an image. The drive mechanism moves the projection unit or a cover member. An electronic control unit controls the drive mechanism to move the projection unit to the projection position in which an image is projected when receiving a predetermined projection preparation request and move the projection unit to the storage position in which no image is projected when receiving a predetermined storage request.</p> |
