<p>A cellular phone includes a first display, a second display, a first touch sensor which detects an input to the first display, a second touch sensor which detects an input to the second display, a CPU which sets and releases a keylock function for disabling the inputs, and a memory which stores a releasing condition of the keylock function including a combination of an input detected by the first touch sensor and an input detected by the second touch sensor. The CPU releases the keylock function with respect to at least one of the first touch sensor and the second touch sensor when inputs detected by the touch sensors and match with the releasing condition stored in the memory while the keylock function is being set.</p> |
