<p>PURPOSE:To surely notify the user of running out of a battery remaining amount by changing the display attribute of a cursor when the running out of the battery remaining amount is detected. CONSTITUTION:A battery remaining amount running out detecting means BC monitors battery voltage normally or periodically and transmits a voltage lowering (remaining amount running out) interrupting signal to a central processing unit CPU when a battery voltage is less than a reference value. Then, the attribute changing means of a cursor is started by interruption from the battery remaining amount running out detecting means BC, the display attribute of the cursor is changed by the processing and battery remaining amount running out is notified to a user. Thus, even when an operator concentrates on work, the battery remaining amount running out can be notified to the operator surely.</p> |
