Abstract
A pen-input unit and a display unit of a mobile terminal apparatus are individually provided so that the display unit can be used only for display, thereby effectively reducing the power consumption of the pen-input unit. The operation panel of the mobile terminal apparatus includes a display unit for displaying a standby screen, a screen displaying the status of call-outgoing/incoming or telephone conversation, a mail-transmission/reception screen, etc. and a pen-input unit having an input panel into which hand-written pen-input is performed and a liquid crystal display unit for displaying a guide display, etc. for input in the input panel. A control unit and ROM start powering the pen-input unit when the display unit enters a display status requesting to perform inputting operation by the pen-input unit, and stop powering the pen-input unit when the display unit enters a display status not requesting to perform an inputting operation by the pen-input unit.
