[Structure] A mobile phone (10) includes a touch panel (38) and a touch control circuit (36) detecting a touch operation, and can set a lock state that a telephone function or the like is restricted. If the lock state is set and a key operation is performed, a message urging to long-depress a touch is displayed on a display (30), and when the touch is detected, a changing object representing an elapse of time is displayed on the display (30). If five (5) seconds elapse in a touched state, a completion image is displayed on the display (30). Then, if a finger is released from the touch panel (38) within three (3) seconds after the completion image is displayed, the lock state is canceled. |
