    摘要: A testing switch is activated manually by the taxi driver or automatically at the end of a trip. When the testing switch is activated, a preselected plurality of pulses is applied to the computing means of the electronic taximeter. If the taximeter is in proper working order, the indicating means of the taximeter will successively and in unison display the numerals from 0 to 9 at the rate or about one per second. If the numerals do not appear in the proper sequence, or if the driver perceives that they appear at a rate markedly different from one per second, or if some or all do not appear whatsoever, he knows that the electronic taximeter is not in proper working order.

    摘要: 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.
