Abstract

PURPOSE:To enable time correction to be automatically performed by providing input-output changeover circuits, external time signal receiving circuit, etc. CONSTITUTION:A time correction instruction code receiving circuit 5 is connected to an analog switch 3 connected to an alarm output circuit 1 via time signal receiving circuit 7 and pulse detector 4. Then, while alarm is not sounding, the analog switch 3 conducts and the sound picked up by a speaker 2 becomes the time correction signal (a) consisting of time correction instruction signal and time signal. In the time instruction receiving circuit 5, this time correction signal (a) appears in the output of 3 input AND gate only in the period when the output (b) of the pulse detector 4 is ''1'' and enters to a shift register. Next, when the specified code are read in a shift register, the time correction instruction (e) is inputted to a time signal receiving circuit 7 and at the specified time, the time signal (g) is inputted to a time correction circuit 8, by which the hour, minute and second counter of the watch circuit 9 are corrected.
