Abstract
PURPOSE: To discriminate the amplitude of a circuit voltage by the number of energized light emission diodes of a plurality of light emission diodes by providing rated voltage display light emission diodes to display the existence of using rated voltage.
CONSTITUTION: A battery 1 supplies a voltage through a power switch 2 to respective electronic circuits. A high voltage generating circuit 3 generates rated voltage upon reception of control from a comparator 4. Rated voltage display light emission diode LED7 and a resistor R7 are connected to the output terminal of the comparator 4. Standard voltage responsive to the discriminated value from a standard voltage circuit 5 is applied to comparators 6W11. The outputs from the comparators 6W11 are applied to light emission diodes LED1WLED6 and resistors R5WR10 froming a display circuit 12.
