ABSTRACT:
The present invention relates to a battery check device particularly for displaying the state of the power source voltage with color. Until now, the battery checker for displaying the state of the power source voltage with color is provided with a plural number of color light emitting elements so as to display the state of the power source voltage with color by selectively driving the determined display element in accordance with the state of the power source voltage. However, by means of this conventional method, the state of the power source voltage can not be displayed continuously, which is inconvenient. In order to eliminate the above shortcoming, the present invention provides a battery checker for continuously displaying the change of the level of the power source voltage with color by continuously changing the color of the display means in accordance with the signal level corresponding to the state of the power source voltage.
