Abstract

PURPOSE:To automatically regulate a timepiece to the correct time in response to the time-signal tone by detecting the time-signal tone through a CCD filter and regulating the time. CONSTITUTION:The time-keeping circuit 2 in a single IC100 generates a control signal two seconds or the like before every hour on the hour to open AND gates 8 and 9. Thereby, from the circuit 2, a driving specific frequency output is applied to the CCD filter 6 in the IC100 and a clock pulse to the control circuit 7. Then, the hour signal based on the time-signal tone through a microphone 4 and an amplification regulating transistor 5 is separated from noises and the like and outputted from the filter 6, and by the control signal outputted by the circuit 7 responding thereto the seconds counter in the circuit 2 is reset. Accordingly, the timepiece is automatically regulated to the correct time in response to the time-signal tone.
