Document Type and Number:
WIPO Patent Application WO/2016/063866
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a power supply control apparatus is provided with: an external power supply monitor unit that determines whether the voltage value of an external power supply is equal to or lower than a predetermined first reference voltage value; a first switch unit that switches power supply with respect to a system control unit from power supply from the external power supply to power supply from a capacitor when the external power supply monitor unit determined that the voltage value of the external power supply is equal to or lower than the predetermined first reference voltage value; a capacitor monitor unit that determines whether the charge quantity of the capacitor is equal to or lower than a predetermined reference charge quantity; and a second switch unit that switches the power supply with respect to the system control unit from the power supply from the capacitor to the power supply from the battery when the capacitor monitor unit determined, at the time of being supplied with power from the capacitor, that the charge quantity of the capacitor is equal to or lower than the predetermined reference charge quantity.
