A mobile phone 10 comprises a display 14, a touch panel 16 provided on the display 14, etc., and a screen lock state that a performance of a predetermined function (mail function or the like) based on a touch operation is invalidated is set. The screen lock state is set if an end key 22b is operated and the display 14 is turned off, for example. Then, the user can cancel the screen lock state by performing a canceling operation. In a case where the display 14 is turned off through an operation of a turn-off key (70), the display 14 is temporarily turned off. In such a case, it is possible for the user to restore the displaying of the display 14 to an original state thereof by operating the end key 22b or the like without canceling operation. |
