Abstract

PURPOSE:To prevent breakdown of the counting contents by cutting off the electric power supply to each part after inhibiting an input signal to the counter in the event of service interruption, and releasing the inhibition of the input signal to the counter after supplying the power to each part in case when the electric power source has been recovered. CONSTITUTION:When the electric power source 11 is turned on, the Schimitt circuit 19 operates, the potential of the point (b) rises, and the electric power source is supplied to the display circuit, etc. Subsequently, the potential of the point (c) rises, and the inhibition of the input signal to the counter 15 is released. When the electric power source 11 is turned off, the potential of the point (c) breaks, and after the input signal to the counter 15 has been inhibited, the potential of the point (b) breaks, and the electric power source to the indicator, etc. is cut off.
