A portable phone device includes a display, a touch panel superimposed on the display and configured to detect a touch operation, an area defining module configured to define within the touch panel a restricted area in which acceptance of the touch operation is restricted, and a determination module configured to determine whether or not a screen being displayed on the display is a target screen for defining the restricted area. The area defining module defines the restricted area based on that the screen being displayed on the display is determined to be a target screen by the determination module. |
