Abstract
A display control unit makes a reference to a display off-time table to change automatic turn-off time (automatic interruption time) of a display unit, which is set to a off-timer as the residual capacity of the battery is changed. The off-timer starts measuring the time when no input is performed by the operation of the user. When the measured time reaches the set time, a switch circuit (SW) is switched off so that the backlight of the display unit is turned off.
