Summary:PROBLEM TO BE SOLVED: To provide an image projection device that can suppress short circuit due to a luminescent material even when a power cord is pulled out from a power supply or the power cord is pulled out from a device body.SOLUTION: When detecting a pull-out operation on the basis of a result of detection performed by a first pull-out sensor 111 and a result of detection performed by a second pull-out sensor 112, a main control part 101 executes mercury bridge suppression processing of increasing a power supplied to a light source 30, changing an output waveform output to the light source, and increasing the rotation speed of a light source fan 71 that cools a light emitting part.SELECTED DRAWING: Figure 7 【課題】電源から電源コードが引き抜かれたり、装置本体から電源コードを引き抜かれたりしても、発光物質による短絡を抑制することができる画像投写装置を提供する。【解決手段】メイン制御部１０１が、第一引き抜きセンサ１１１の検知結果や第二引き抜きセンサ１１２の検知結果に基づいて、引き抜き動作を検知したら、光源３０に供給する電力を増加させたり、光源に出力する出力波形を変更したり、発光部を冷却する光源ファン７１の回転数を上げたりする水銀ブリッジ抑制処理を実行する。【選択図】図７
