Abstract
PURPOSE:To obtain an electronic bar graph display device which can display the residual amount of a liquid with high accuracy, by increasing the drive voltage at a bar graph display part and at the same time switching the scale when the amount of liquid becomes less than a prescribed level. CONSTITUTION:A constant current is flowed to a liquid measure detection sensor 1 from a constant current source 2, and the output is displayed at a bar display 5 via a voltage converter 7 and a decoder 9. Furthermore the output of the sensor 1 is supplied to a prescribed voltage detecting circuit 8, and the output of the circuit 8 is delivered to the converter 7 when the output of the sensor 1 becomes less than a prescribed level. Thus the output of the converter 7 is increased, and at the same time the display of a scale display is switched via a decoder driver 10. In such constitution, the range is switched and displayed for the scales of displays 5 and 6 when the amount of liquid becomes less than a prescribed level. Thus the display is possible with high accuracy although the residual amount of liquid is reduced.
