Abstract
A digitizer panel for input with an electronic pen is detachably attached a laptop PC. The laptop PC includes a touch screen housed in a display housing. The display housing is formed of material having electromagnetic wave transmissivity such as GFRP or CFRP. On the back face of the display housing, an electromagnetic induction type digitizer panel can be detachably attached. The digitizer panel and the laptop PC are able to wirelessly communicate with each other. When the digitizer panel is attached, an electronic pen is brought close to the touch screen for input. When the digitizer panel is not attached, the electronic pen is directly brought close to the digitizer panel for input.
