PURPOSE:To confirm duration of a call after the end of call by displaying the duration of the call on a display part not only during call but also during waiting after the end of call. CONSTITUTION:A control part judges whether it is under call or not and when it is under call, it is detected whether a duration of the call calling key 6 is depressed or not. When the key 6 is depressed, the duration of the call is displayed on a display part 2 in real time. When the key 6 is depressed during waiting after the end of a call, the duration of the call of the final call (last time) is displayed on the display part 2 for fixed time. Thus, since the duration of the call calling key 6 is operated during the call, the duration of the call is displayed on the display part 2 in real time. On the other hand, by operating the duration of the call calling key 6 during waiting, the duration of the call in the case of the last call is displayed for fixed time. |
