Abstract

In the taximeter disclosed, a microprocessor responds to a first set of pulses representing time and a second set of pulses representing distance and receives data representing a tariff from a constant store. The microprocessor calculates fares and advances the fares continuously on the basis of new calculations, while entering the results in a display for the driver and passenger. The constant store is in the form of a non-volatile memory for receiving programming data from an external source through a connector.
