It comprises a data storage circuit 6, a control circuit 10, an internal data output circuit 12, an external output interface circuit 14, a function switch 16, and a mode changeover switch 17.

The signal received by the reception circuit 1 is restored by the reception signal restoration circuit 2, and sent onto the signal line 101 to become a reception data signal. The received data is sent to the paging signal detection circuit 3, where it is checked whether or not the own paging code is present in the received signal. When the own call code is detected by the signal detection circuit 3, the call signal detection circuit 3 sends a call detection signal to the control circuit 10 via the signal line 109, and the control circuit 10 is initialized to accept data information. This is done by Control circuit 1
0 sends a receive data gate control signal on signal line 102, which causes the first AND gate 4 to open. When the first AND gate 4 opens, the data signal on the signal line 101 is sent to the receive data decoding circuit 5. The data signal is converted into a system data format by the reception data decoding circuit 5 under the control of the reception data decoding control signal sent from the control circuit 10 via the signal line 110, and the data is converted into a system data format as a data signal. The signal is sent to the memory circuit 6 and the second AND gate 7. The data signal sent to the data storage circuit 6 is sent to the data storage circuit 6 via the signal line 103 and stored in the data storage circuit 6 under the control of the data storage circuit control signal present on the signal line 109. Ru. The second AND via signal line 103
The data signal sent to the gate 7 is sent to the signal line 11.
Under the control of the receive storage data gate control signal applied to the first AND gate 7 via 1,
It passes through a second AND gate 7 and is applied to an OR gate 9. The data signal passing through OR gate 9 is sent to fourth and fifth AND gates 11 and 13. The third AND gate 8 is a gate for transmitting the data stored in the data storage circuit 6 in the same manner as described above. Under the control of a receive storage data gate control signal applied via signal line 111, said data signal is applied to OR gate 9 through a third AND gate 8. OR gate 9 is a gate for mixing the outputs of these AND gates. The output of OR gate 9 is applied to fourth and fifth gates 11 and 13, which are controlled by control circuit 10 according to the setting of mode changeover switch 17. That is, the mode changeover switch 17

On the other hand, when the fifth AND gate 13 is open, the data signal is applied to the fifth AND gate 13 and the external output interface circuit 14 via the signal line 106, and is output by the external interface circuit 14. The data signal is converted into serial data or parallel data and sent as external output data from the external output terminal 15 to an external device. The function switch 16 is used to reset the alarm sound when calling and to control data signals, and can read out stored data during standby. That is, in order to send out the stored data from the data storage circuit 6, the signal line 1 is connected from the control circuit 10.
