  • Patent number: 4056709
    Abstract: A digital taximeter provides a visual read out of a first and a second multi-digit number. Instead of a plurality of discrete one-digit illuminated-digit display units arranged together to be capable of displaying multi-digit numbers, use is made of a single multi-digit illuminated-digit display unit having a row of equal-size digit zones. One or more of the middle ones of the digit zones are blocked from view to form a first and a second group of digit zones respectively adapted for the display of the first and the second multi-digit numbers and located to either side of the digit zones which are blocked from view. Although the digit zones are actually all of the same size, those of the first group are made to appear larger than those of the second group, in correspondence to the greater importance of the fare indication compared to the extra-charge indication.
