<p>PURPOSE:To effectively utilize a battery by preventing the rest of the battery from being misdetected through simple hardware. CONSTITUTION:A CPU 1 performs operation interruption processing when judging that battery voltage detection data on the battery 4 in an A/D converter 6 becomes lower than a predetermined lower-limit set value of the battery voltage for a certain period of time controlled by a timer 5 so that battery control is not affected by temporarily voltage variation while a heavy load such as a printer 7 and an FDD 8 is driven.</p> |
