Abstract
PURPOSE: To enable to be prepared for setting time out of any ticking display state by giving siren synchronized with a second ticking motion of a clock.
CONSTITUTION: When 1Hz signal put out from a clock circuit 3 is given to a hand indication device through a driving circuit 7, the second hand 6a is step-driven to indicate a time. On the other hand, when 1Hz signal is given to a time signal giving circuit 4, the 3,520Hz signal is given in an interval 1W9 second, 11W19 second ... 51W56 second, the 880Hz signal is given for 0 second, 10 second, ... 50 second, and the 440Hz signal is given for 57, 58, 59 second from a speaker 5 synchronizing with the second hand 6a motion. At this moment the clock to be corrected is set by the indicated time of the hand indicating device 6 and is made to start timing with the sounds generating from the speaker 5 and with the motion of the second hand 6a to set the time.
