Mobile terminal apparatus, and power control method and storage medium recording program therefor

A power control method for a mobile terminal apparatus having a pen-input unit, comprising:

• a power control request detecting step of detecting a request as to whether or not the pen-input unit is to be powered, calling a power ON specifying unit when the pen-input unit is to be powered, and calling a power OFF specifying unit when the pen-input unit is not to be powered;
• a power ON specifying step of a power control executing unit generating necessary information for powering the pen-input unit, and the power control executing unit being called according to the information;
• a power OFF specifying step of the power control executing unit generating necessary information for powering down the pen-input unit, and the power control executing unit being called according to the information;
• and
• a power control executing step of powering or powering down the pen-input unit.
