Summary:To provide a gas meter capable of resetting a CPU on the basis of an operation state even when the CPU is operating.SOLUTION: The gas meter includes: a monitoring unit 11 that monitors the clock frequency of a CPU of an own machine and determines whether the clock frequency is within a range of the threshold; a reset unit 12 for resetting the CPU when the monitoring unit 11 has determined that the clock frequency is not within the range of the threshold; and a recovery unit 14 that, when the reset unit 12 has performed the reset, recovers the own machine to the state before the reset.SELECTED DRAWING: Figure 1 【課題】ＣＰＵが動作している場合であっても、動作状況に基づくＣＰＵのリセットを行うことができるガスメータを提供する。【解決手段】自機のＣＰＵのクロック周波数を監視し、当該クロック周波数が閾値の範囲内であるか否かを判断する監視部１１と、監視部１１が、クロック周波数は閾値の範囲内でないと判断した場合に、ＣＰＵのリセットを行うリセット部１２と、リセット部１２がリセットを行った場合に、自機を、リセットが行われる前の状態に復旧する復旧部１４とを備えた。【選択図】図１
