Abstract
There is provided an electronic taxi fare meter wherein the tariff travel distance and the tariff travel time of a taxi are converted into pulse signals representing digital quantities, and these pulse signals are increased by a premium fare computing circuit comprising a combination of counters. The premium fare mechanism is thus reduced in size and weight as compared with the conventional mechanisms of the mechanical type, and accurate computation of the fares at premium rates can also be effected for both the tariff travel distance and the tariff travel time of a taxi. Further, the use of the digital techniques makes the apparatus less susceptible to supply voltage variations and ambient temperature changes, makes the designing of the apparatus with integrated circuits possible, and ensures a higher degree of reliability in the operation of the apparatus.
