It is calculated and displayed by the taxi meter based on the charge system data stored in the d-Only Memory) and the running pulse from the running sensor. This PROM is replaced with a new PROM storing the revised fee system data every time the fee system is revised.

[0003] In recent years, when the fare exceeds a certain amount, a long-distance discount system in which the excess amount is discounted at a certain rate, and an additional charge system such as a time-specific vehicle allocation fee different from the above-mentioned pick-up fee, have been proposed. In the taxi industry, for example, the introduction of new discounts, surcharges, and additional charges has been introduced in some areas, and attempts are being made to improve passenger services in terms of fares. However, fares and surcharges that apply such new surcharges, or
In order to display the total fare for the taxi meter alone, it is necessary to modify the existing taxi meter or replace it with a new taxi meter. Therefore, in areas where the long-distance discount system described above was actually introduced, a fee display device was externally attached to the existing taxi meter,
This tariff setting device performs both tariff setting such as long-distance discount and time-specific vehicle allocation, and display of fare discount applicable fare and time-specific vehicle allocation fee.

In an external charge display device for setting a tariff of such a new additional charge system and displaying a ride fee etc. after applying the additional charge system, an internal E ² PROM is used.
