ABSTRACT:
A device for detecting a voltage of a battery for use in electronic apparatus and appliances, the detector being constructed with a display device which include segments to display input data and processed data and segments to display particular data; a time-division signal output device to produce time-division output signals for driving the display device in a time-division mode; a voltage detector to detect a voltage of a source battery in synchronism with the time-division output signals from the time-division signal output device; a voltage comparator to compare the battery voltage as detected by the voltage detector with a reference voltage; and a segment driver to drive the segments which have been pre-selected from the segments in the display device based on the result of comparison by the voltage comparator.
