Abstract

PURPOSE:To correct the time contents of analog and digital systems by one motion by letting the command of a switch circuit which forms a correction signal when operated from the outside be effected simultaneously on both analog and digital counters from an auxiliary analog counter. CONSTITUTION:The outputs of a frequency dividing circuit 2 are inputted to an analog counter 7 and a digital counter 8 and the same time contents are displayed on an analog display means 6 using the hands and a digital display means 10 using a liguid crystal cell. when an auxiliary analog counter 11 recives the command of a switch circuit 12 which forms a correction signal to be generated when operated from the outside, it investigates the contents of the analog counter 7 and excites a correction pulse forming circuit 13, which in turn corrects the analog display means 6 by way of a driving pulse screening circuit 14. On the other hand the auxiliary analog counter 11 acts simultaneously on the digital counter 8 and also corrects the contents of the digital counter 8 according to the contents of the analog counter 7.
