PROBLEM TO BE SOLVED: To cool the inside of an electronic apparatus case while taking the temperature in a housing into consideration when an electronic equipment such as an image pickup device is stored in the housing.SOLUTION: There is provided an electronic apparatus including a case, a cooling fan which cools a heat generation part in the case, driving means of driving the cooling fan, and first determining means of determining whether the case is stored in a housing. The electronic apparatus has temperature detecting means of detecting a first temperature at a first position of the electronic apparatus and a second temperature at a second position relatively closer to the heat generation part than the first position of the electronic apparatus, and switching means of switching the rotating speed of the cooling fan according to the temperature difference between the first temperature and second temperature when the first determining means determines that the case is stored in the housing, and the switching means makes the rotating speed of the cooling fan faster when temperature difference between the first temperature and second temperature is a second temperature difference larger than a first temperature difference than when temperature difference between the first temperature and second temperature is the first temperature difference. 【課題】 撮像装置などの電子機器がハウジングに収納された場合に、ハウジング内部の温度を考慮して電子機器筐体内の冷却を行う。【解決手段】 筐体と、筐体内部の発熱部を冷却する冷却ファンと、冷却ファンを駆動する駆動手段と、筐体がハウジングに収納されているか否かを判定する第１の判定手段と、を備えた電子機器であって、電子機器の第１の位置の第１温度と、電子機器の第１の位置よりも相対的に発熱部に近い第２の位置の第２温度とを検出する温度検出手段と、第１の判定手段により筐体がハウジングに収納されていると判定された場合に第１温度と第２温度の温度差に応じて冷却ファンの回転速度を切り替える切替え手段と、を有し、切替え手段は、第１温度と第２温度の温度差が第１の温度差である場合よりも、第１温度と第２温度の温度差が第１の温度差よりも大きい第２の温度差である場合の方が冷却ファンの回転速度を速くすることを特徴とする構成とした。【選択図】 図３
