A reception means extracts a time code from a radio signal received by an antenna, thereby outputting it to a control means. The control means obtains an information of a present time instant from the time code extracted by the reception means and corrects a present time instant being clocked by its own clock means. A display means displays the present time instant being clocked by the clock means. In a case where there has been judged that the time code is not outputted from the reception means, the control means controls so as to alter a tuning frequency by altering a capacity value of a variable capacity diode. |
