Abstract
Abstract A taximeter of the type adapted to register the values of a plurality of metered variables, for instance total mileage, passenger mileage, waiting time, total fares, etc. A pulse generating unit generates pulses corresponding to increments in the values of such metered variables. A plurality of counter units counts the pulses generated by the pulse generating units and registers digital information corresponding to the values of the metered variables. A digital display unit is capable of displaying the numerical value of any of the metered variables. A selector unit selects which of the metered variables is to have its numerical value displayed.
