Electronic clock devices

Claim 1

An electronic clock device comprising: a clock signal generator for generating a clock signal having a highly stable frequency; first counter means responsive to said clock signals for counting the six values of units of ten-seconds obtained from the clock signal of said clock signal generator at an interval of ten seconds, for generating outputs corresponding to said six values and for generating a stepping output every 60 seconds; second counter means for counting units of minutes which is operated stepwisely by the stepping output of said first counter means and for generating a stepping output every 60 minutes; third counter means for counting units of hours which is operated stepwisely by the stepping output of said second counter means and for generating a stepping output every 24 hours; fourth counter means for counting the seven valves of the days of a week which is operated stepwisely by the stepping output of said third counter means and for generating seven output values which correspond to the respective 7 days of the week; first display means coupled to and displaying the contents of said second and third counter means; second to eighth display means coupled to said fourth counter means providing respective unique displays corresponding to the seven output values of the output of said fourth counter means; and display switching means for displaying the six values of the output of said first counter means by using six display means of said second to eighth display means.
