PURPOSE:To improve the efficiency of a channel, by receiving a data having long data length and high using frequency as a specific data in the form of an abbreviated time length, then restoring the shortened data to the original data. CONSTITUTION:Simultaneously with the detection of the coincidence with self- code, a calling signal/message signal detecting circuit 23 generates a data selecting signal to find the timing of message data and sends the signal to a control circuit 29. The circuit 29 opens the gate of a message storing circuit 26 to apply and store message data (b) detected from the circuit 23 to/in the circuit 26. When a call switch 29a for the circuit 29 is turned on after an optional period, the data stored in the circuit 26 are read out and applied to a message data restoring circuit 27 to restore only the abbreviated data to the original data. The data other than the abbreviated data are taken out as they are and set up to the timing to be outputted. Obtained message data are supplied to a message displaying circuit 28 and displayed by the voice, character, etc. |
