Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of reliably detecting mounting/dismounting of a battery without causing useless electric power consumption.SOLUTION: The electronic apparatus includes: a main battery (10) having a battery and a thermistor (11); a PU resistance (37) of a power source A; a comparator (39) that compares a predetermined comparison voltage (Vo) and a voltage (Va) on a node of a signal line of a temperature detection signal (10b (signal 31a)) from the thermistor 11 and a signal line of the PU resistance (37); a storage unit (33); and a control unit (20) that sets 1 of a detection flag to the storage unit (33) when the voltage Va is the comparison voltage Vo or more in the comparison by the comparator (39).SELECTED DRAWING: Figure 1
