PURPOSE:To improve the memory efficiency of a display data memory circuit by displaying a call signal with no message by means of a call memory circuit and a call display production circuit. CONSTITUTION:The data transmitted after the call signal is decoded by a decoder 3, and a control circuit 16 decides whether the data contains a message. Then a switch 13 performs switching between the call signal processing with a message and that with no message. The call signals with no message are rearranged within a call memory circuit 14. A call display production circuit 15 produces the display data with no message and displays it to a display device 12 via a display driving circuit 11. While the message of the call signal containing the message is converted into the display data by a display data production circuit 7 and stored to a display data memory circuit 8. Then the contents of the message are displayed to the device 12 via the circuit 11 for the data of the cir cuit 8. |
