IMAGE PROJECTION APPARATUS |
| 摘要 |
An image projection apparatus includes: an exhaust fan configured to discharge air in the apparatus to outside of the apparatus; a light source; and a plurality of ducts each having an air intake port facing the light source, and arranged side by side in a rotation axis direction of the exhaust fan. A duct closer to the exhaust fan in a rotation axis direction of the exhaust fan, has a larger flow path sectional area and has an outflow port from which air flows out, placed closer to the light source, in a direction perpendicular to the rotation axis direction of the exhaust fan. |
