<p>In a power supply control apparatus capable of connecting an AC adapter (11), it is determined by a controller (16) whether or not the AC adapter (11) is connected. When a battery (13a; 13b) is set in the apparatus, it is determined whether the battery (13a; 13b) is in a low battery state. When the AC adapter (11) is connected and the set battery (13a; 13b) is in a low battery state, charge operation for the battery (13a; 13b) is started. During charging, a charged state is monitored on the basis of the current value detected by a current detector (14a; 14b) and a charge time measured by a timer (16a). When the charge amount exceeds a predetermined amount, or the charge time exceeds a predetermined charge time, the charge operation is completed and the battery (13a; 13b) is used as a power supply. <IMAGE></p> |
