ABSTRACT:
A power source device for electronic counting systems comprising an a.c. power source, a first d.c. power circuit connected to the a.c. power source for supplying an object detecting device with a d.c. power, a second d.c. power circuit connected to the a.c. power source for supplying a counter with a d.c. power, the rate of discharge of the first d.c. power circuit being less than that of the second d.c. power circuit so as to prevent the counter from receiving signal from the detecting device during power failure of the a.c. power source.
