摘要

PROBLEM TO BE SOLVED: To automatically reset the power supply time record from the auxiliary battery of terminal equipment for an emergency informing system at the time of exchanging the auxiliary battery. SOLUTION: A power source controller 17 monitors the voltage of an auxiliary battery 18, and a signal when the battery is turned into a certain fixed voltage or less is outputted to a control part 12. The control part 12 deletes power supply time recording from the auxiliary battery 18 from a storage part 15. When a user exchange the auxiliary battery 18 with a new auxiliary battery 18, the measurement of a time when the new auxiliary battery 18 is used is started. A single when the decrease of the voltage is continued in a fixed time or more is used as a condition for resetting power supply time recording from the auxiliary battery 18 into an initial state so that any reset due to erroneous recognition in the case of the hit of a power source or the like can be prevented.
