    • PROBLEM TO BE SOLVED: To provide a radio correction clock in which a main control circuit can be reduced in size, and which can be reduced entirely in size as a result.SOLUTION: A radio correction clock includes a decode IC 210 and a microcomputer 200 for clock. The decode IC 210 inputs a reference signal and acquires and outputs decode information by discriminating one code signal from among a plurality of code signals contained in a radio signal on the basis of the inputted reference signal. The microcomputer 200 for clock is comprised of a circuit different from the decode IC 210, inputs the reference signal, adjusts a frequency of the inputted reference signal, counts time information for notification on the basis of the adjusted reference signal, inputs the decode information and corrects the counted time information for notification on the basis of the inputted decode information. The microcomputer 200 for clock outputs a reset signal which is generated on the basis of the adjusted reference signal, and the decode IC 210 resets the reference signal in accordance with the reset signal.
