Abstract

a power source device which receives an external power and converts the external power to a memory driving voltage and supplies the memory driving voltage to a memory; an internal power supplying means which supplies power to the memory by a mounted battery if the memory driving voltage becomes below the voltage of the mounted battery; a mounted battery discrimination means discriminating whether the mounted battery is a primary battery or a secondary battery by the size of the mounted battery; and a charge control means charging the secondary battery with the external power when the mounted battery is a secondary battery.
