Abstract

PURPOSE:To decrease the number of switches, by enabling to perform a second resetting with a crown operation in an electronic clock having an optical display device provided with a crown. CONSTITUTION:When a crown switch RS is turned on, an output M1 of a storing circuit 6 becomes 1. Then, when the switch RS is turned off, an output of an NOR gate NO1 in an operational output circuit 5 becomes 1 and an and gate AN1 outputs a second resetting signal SR for one period of a clock CL. A second of a clock counting circuit is reset by the second resetting signal SR.
