ELECTRONIC EQUIPMENT

PROBLEM TO BE SOLVED: To provide electronic equipment that can perform heating and function confirmation of an auxiliary battery for an auxiliary power supply, with a simple configuration.SOLUTION: A heater resistor 16 for heating an auxiliary battery 14 incorporated in an on-vehicle emergency report device 1 as an auxiliary power supply of a main battery 7 is provided. First and second power supply switches 17 and 18 for forming first and second power supply paths for supplying power to the heater resistor 16 from the main battery 7 and the auxiliary battery 14, respectively, are provided. A control circuit 3 controls the first and second power supply switches 17 and 18 to form the respective power supply paths and to perform energization to the heater resistor 16. 【課題】予備電源用の補助バッテリの加熱と機能確認とを、より簡単な構成で行うことができる電子機器を提供する。【解決手段】主バッテリ７の予備電源として車載用緊急通報装置１に内蔵されている補助バッテリ１４を加熱するためのヒータ抵抗１６を備えると共に、主バッテリ７，補助バッテリ１４からヒータ抵抗１６にそれぞれ電源を供給する第１，第２電源供給経路を形成するための第１，第２電源スイッチ１７，１８を備え、制御回路３は、第１及び第２電源スイッチ１７，１８を制御して各電源供給経路を形成し、ヒータ抵抗１６への通電を行う。【選択図】図１
