Abstract

PURPOSE:To save electric power so that a battery is consumed only at the time of abnormal detecting operation by stopping the informing operation of an informing means when a working power supply voltage is less than a prescribed voltage. CONSTITUTION:When the voltage of a battery 45 is low, LED display using an abnormality displaying LED 7 is stopped. When a common terminal C of a battery test switch 9 is connected to a normally-closed terminal NC in a normal state, the voltage of the battery 45 is divided by resistors 77, 78 and the divided voltage is supplied to an inverter 79. When the voltage of the battery 45 dividedly supplied to the inverter 79 is dropped, the output of the inverter 79 is turned to a high level and the high-level signal is supplied to the base of a transistor (TR) 67 through an OR circuit 82. Consequently, the TR 67 is turned off and the LED 7 is not turned on, so that the power consumption of the battery 45 can be suppressed.
