PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus capable of retaining a high reliability even under an environment of a strong magnetic field.SOLUTION: An electronic endoscope includes an MRAM for storing endoscope intrinsic information data, and a magnetic sensor for detecting the size of magnetism received by the MRAM. When the magnetic sensor detects magnetism of a prescribed threshold or higher, data of at least part of items of the endoscope intrinsic information data are evacuated into a memory of an electronic endoscope processor as evacuation data. When the magnetism detected by the magnetic sensor becomes smaller than the prescribed threshold, the data evacuated into the memory of the electronic endoscope processor are restored to the MRAM as the endoscope intrinsic information data.COPYRIGHT: (C)2013,JPO&INPIT【課題】強磁界の環境下であっても高い信頼性を維持することが可能な電子内視鏡装置を提供すること。【解決手段】電子内視鏡が、内視鏡固有情報データを記憶するMRAMと、MRAMが受ける磁気の大きさを検出する磁気センサとを備え、磁気センサが所定の閾値以上の磁気を検出したときに、内視鏡固有情報データの少なくとも一部の項目のデータを退避データとして電子内視鏡用プロセッサのメモリに退避させ、磁気センサによって検出される磁気が所定の閾値よりも小さくなったときに、電子内視鏡用プロセッサのメモリに退避させたデータを内視鏡固有情報データとしてMRAMに復旧させる。【選択図】 図1
