PURPOSE: To prevent contents to be informed from being forgotton by specifying contents determined between the call side and a receiver by numerizing an address to be communicated or a matter and selecting and displaying the item.

CONSTITUTION: A control part 5 executes a comparison of an address signal from a radio part 2 with data from an EEPROM (inherent call number storing means) 6 storing the inherent callee number of a receiver under error control and controls a comparing means for judging whether calling is executed or not. After confirming the call, message data following the call are stored in a memory (storage means) 9. The control part 5 calculates a display position from the received message data based upon the stored message data and sends the calculated result (output) to the 1st step motor in a message ring part 12. The 1st stepping motor transmits the rotational spindle of its rotor to a message vehicle and the message is specified and displayed in accordance with the position of the vehicle.
