TIME ADJUSTING DEVICE FOR ELECTRONIC CLOCK

摘要

An electronic clock having a clock circuit in which reference clock pulses are frequency divided so as to be applied to a time indicating device for stepwise switching the time indication therein one by one unit of time for indicating the time, and the time indication is corrected stepwise one by one unit of time in timed relationship to the reference clock pulses by applying time correction pulses to the clock circuit until the correction of time is achieved. The device for correcting the time indication comprises a time correction signal generating circuit capable of applying time correction pulses of variable frequency to the clock circuit in timed relationship to the reference clock pulses so that the speed of the stepwise correction of time can be arbitrarily adjusted. The clock has a timer and the device for correcting the indication of time of the electronic clock can be used for correcting the time of the timer at which the timer is actuated, by switching the indication of time in the indicating device by the action of the switch means together with the readjustment of the set timer time in the clock circuit.
