Abstract

PURPOSE: To correct the time on an electronic clock in a reduced period of time with a single correction switch alone by supplying a correction pulse to an additional counter in accordance with the time difference while the correction switch is depressed.
CONSTITUTION: When a correction switch 1 is depressed, a pulse is applied to a synchronous differentiating circuit 3 through a chattering preventive circuit 2, and an output SIN from the differentiating circuit 3 is input into a one-minute counter 4 through an OR-gate 13. A correction pulse is inputted into the one-minute counter 4 every time the correcting switch 1 is turned on and off. When the correcting switch 1 is depressed for a certain period of time in excess of a predetermined period of time, a clock pulse ϕ is counted by a counter 9 by an output from a flip- flop 6, and a flip-flop 7 is set by an output from the counter 9. The clock pulse ϕ is supplied to the one-minute counter 4 by a set output SFF2 from the flip-flop 7, and a clock pulse ϕ', which has been frequency-divided by a flip-flop 8, to a ten-minute counter 5. Accordingly, the correction of time can be carried out in a short period of time.
