PURPOSE:To secure the instantaneous display or recording for the talking time and its charge, by displaying and recording the talking time and its charge through the one- touch operation of the key input while talking or after the end of talking and based on the called party and its telephone number which are memorized previously in the ROM part. CONSTITUTION:Both the called party and its telephone number which are memorized previously in ROM part 15 are pressed down with the one-touch operation of the talking mode at key input switch operation part 13, thus the telephone of the called party being called out. Then timer part 14 operates with start of the talking, and then the operation is carried out by CPU17 for counting of the time, the charge and others. And the charge converting value of the talking time in the course of talking is displayed on display unit 19 under the talking mode; and then the talking time and its charge converting value are recorded at print recording part 20 when the talking is over. Thus the talking is possible through the one-touch operation, and furthermore both the talking time and its charge can be immediately displayed or recorded. |
