PROBLEM TO BE SOLVED: To provide an endoscope apparatus which includes a lamp cooling mechanism, and in which radiated heat from a light source such as a lamp is effectively cooled even when a main power source is turned OFF during a cooling operation.SOLUTION: In the endoscope apparatus including a cooling fan for cooling radiated heat from a lamp, the cooling fan is operated continuously for a fixed period T0 even after the lamp is put out. Then, when the main power source is turned OFF during a cooling operation after usual lamp put-out by a lamp button, the cooling fan is continuously operated for a remaining period T2 excluding a cooling operation period T1 until the main power source is turned OFF.COPYRIGHT: (C)2013,JPO&INPIT【課題】ランプ冷却機構を備えた内視鏡装置において、冷却動作中にメイン電源がOFFになっても、ランプなどの光源からの放熱を効果的に冷却する。【解決手段】ランプからの放熱を冷却する冷却ファンを備えた内視鏡装置において、ランプ消灯後も冷却ファンを一定期間T0継続して動作させる。そして、ランプボタンによる通常のランプ消灯後における冷却動作途中でメイン電源がOFFになると、それまでの冷却動作期間T1を除いた残りの期間T2だけ、冷却ファンを続けて動作させる。【選択図】図2
