Abstract
An emergency information terminal includes two power supply circuits supplying power to the internal circuits including a controller. If one of the power supply circuits fails, the other power supply circuit supply power, and the operation of the terminal is maintained. Even in case of emergency such as traffic accident or sickness, an emergency call can be notified. Further, the controller detects a trouble in the power supply circuit, and informs the user of the trouble.
