Abstract
PURPOSE: To allow a clock to show correct time constantly, by furnishing the clock with an ability to let the user know a failure to obtain a periodical time signal, whereby the correction of time can be carried out arbitrarily by hand.
CONSTITUTION: A motor 5 is driven with a signal obtained by subjecting a timing pulse 1 to frequency division 2 show the time at 7 through gears 6. A signal from the frequency divider 2 is applied to a counter circuit 8 to digitally indicate a time and a date at 11. A timing pulse is supplied to a switching circuit 12, and when an instant of giving a time signal has drawn near 14, a timing pulse is supplied from the circuit 12 to a counter memory circuit 15. When the counter memory circuit 15 is full over, an unsynchronized indication circuit 16A is energized to show that a correction of a time has not been carried out, and to have the user correct the time by operating a manual switch 19. When a time signal is received at a proper time, a switching off instruction for the circuit 12 is given from a digit-zero resetting circuit 16, and the time is corrected at the same time.
