PURPOSE:To decrease the display space, by providing a flickering mechanism of dots at the switching of the display to decrease the cost of the display device. CONSTITUTION:When 5 is set as a discriminating reference input of a comparator 3, an output of A>B outputs H level when the largest digit of the residual amount is >=6, and an output of A<B produces H level when <=4. Supposing that the residual amount is 80% or so, an output of A=B of the comparator 3-1 goes to H level, this output is ORed by an OR gate 4-5, an AND gate 5-5 is selected, an a clear input of J-KFF8 is controlled by the state of A<B output of the comparator 3-5. In the range of 84-80%, then a light emitting diode 7-1 flickers. Further, the residual amount of all sections is displayed by lighting or flickering light emitting diodes 7-1, 7-2- at the changeover point of the range divided into 5. |
