PROBLEM TO BE SOLVED: To improve the reliability of security by providing a masking processing part for turning a permission code included in received message information to non-display. SOLUTION: The masking processing part 12 for masking the permission code is provided, only calling messages including the permission code stored in a permission code memory 15 beforehand are received and stored in a message memory 6 and the reception of the other calling messages is denied. For instance, the call termination processing of the message is executed only in the case that the permission code for which the numerals of the lower four digits of the calling message are '1234' is included. Then, the received message is stored in the message memory 6, the '1234' of the permission code is masked, the message contents of remaining higher digits are displayed on a message display part 8 and singing is outputted from a speaker 7 through a singing processing part 10. At the time, since the permission code is masked and is not displayed, even when the reception state of this radio type individual receiver 14 is viewed by a unspecified person, the permission code is not recognized from the appearance. |
