PROBLEM TO BE SOLVED: To provide an image projection device that can improve operability in adjusting an exhaust direction associating with change of installation orientation of a device body.SOLUTION: The image projection device that performs image projection using light from a light source, comprises exhaust means for exhausting air warmed by a heat source within a device body, an air exhaust that exhausts the warmed air out of the device body, exhaust direction changing means 80 that changes an exhaust direction from the air exhaust, and a light source. In the image projection device, the exhaust direction changing means causes the exhaust direction from the air exhaust to have a certain direction to a gravity direction, irrespective of an installation orientation of the device body.SELECTED DRAWING: Figure 8 【課題】 装置本体の設置向きの変更に伴う排気方向の調整における操作性を向上させることができる画像投影装置を提供すること。【解決手段】 装置本体内の熱源によって暖められた空気を排出するための排気手段と、暖められた空気を装置本体外に排出する排気口と、排気口からの排気方向を変更する排気方向変更手段８０と、光源とを備え、光源からの光を用いて画像の投影を行う画像投影装置において、前記排気方向変更手段が、前記排気口からの排気方向を、装置本体の設置向きにかかわらず、重力方向に対して一定の方向となるようにした。【選択図】図８
