PROBLEM TO BE SOLVED: To provide an apparatus monitoring device for enabling a control part of an apparatus to properly determine abnormality that occurs with power supply of the apparatus interrupted without wasting power consumption as much as possible.SOLUTION: The apparatus monitoring device includes: a state monitoring circuit 10 for receiving power supply from an operation power supply 51 during standby different from a main power supply 50 of a control unit 100 to operate, monitoring an apparatus to detect that the apparatus has abnormality with power supply to the control unit interrupted, and holding monitoring information during standby representing the result of abnormality; and an AND circuit 15 that functions as a buffer part for receiving power supply together with the control unit to operate, and taking over the monitoring information during standby in a state where the control unit can acquire the monitoring information during standby from the state monitoring circuit to hold the monitoring information during standby when power supply to the control unit is returned.SELECTED DRAWING: Figure 1 【課題】電力消費を極力無駄にすることなく、機器の電源供給が遮断された状態で発生した異常に対して当該機器の制御部が適切な判定をできるようにした機器監視装置を提供する。【解決手段】制御ユニット１００の主電源５０と異なるスタンバイ中動作電源５１により電源供給を受けて動作し、制御ユニットに対する電源供給が遮断された状態において、機器を監視して異常であることを検出し、その結果を表すスタンバイ中監視情報を保持する状態監視回路１０と、制御ユニットへの電源供給が復帰されたときに、制御ユニットとともに電源供給を受けて動作し、スタンバイ中監視情報を状態監視回路から制御ユニットにて取得可能な状態で引継いて保持するバッファ部として機能するアンド回路１５と、を有する。【選択図】図１
