To provide a measuring instrument which can reduce dark current.SOLUTION: A measuring instrument 100 is mounted on a vehicle, and lights a light source 70 which notifies actuation of an emergency flashing pilot lamp indicator when a hazard SW 1 for operating the emergency flashing pilot lamp is changed from the OFF state to the ON state by an operation. The measuring instrument 100 comprises: a control part 60 which controls lighting of the light source 70; an electric power source IC 10 which supplies electric power source to the control part 60 on the basis of electric power from a battery 2; and an electric conduction state changeover circuit 20 which performs changeover between an electric conduction state that the battery 2 and an enable terminal EN of the electric power source IC 10 are electrically conducted and a non-electric conduction state which becomes non-electric conduction. The electric conduction state changeover circuit 20 activates the electric power source IC 10 by changeover from the non-electric conduction state to the electric conduction state when the hazard SW 1 is changed from the OFF state to the ON state, and the electric power source IC 10 starts supply of an electric power supply to the control part 60 according to the actuation.SELECTED DRAWING: Figure 1

    【課題】暗電流を低減することができる計器を提供する。【解決手段】計器100は、車両に搭載され、非常点滅表示灯を作動させるためのハザードSW1が操作によってオフ状態からオン状態となったことに応じて、非常点滅表示灯の作動を報知するための光源70を点灯させる。計器100は、光源70の点灯を制御する制御部60と、バッテリ2からの電力に基づいて制御部60に電源を供給する電源IC10と、バッテリ2と電源IC10のイネーブル端子ENとが通電される通電状態と、非通電となる非通電状態とを切り替える通電状態切替回路20と、を備える。通電状態切替回路20は、ハザードSW1がオフ状態からオン状態となったことに応じて、非通電状態から通電状態へと切り替えることで電源IC10を起動させ、電源IC10は、起動したことに応じて、制御部60への電源の供給を開始する。【選択図】図1
