THE FARE REPRESENTING SHAFT OF A TAXIMETER IS DRIVEN BY ONE-WAY CLUTCHES FROM DISTANCE AND TIME DRIVE MEANS. WHILE THE DISTANCE DRIVE MEANS DRIVE THE SHAFT AT VARYING SPEEDS, THE TIME DRIVE MEANS HAS A MOTOR WHICH ROTATES AT A CONTINUOUSLY CONSTANT SPEED SO THAT UNDESIRED SIMULTANEOUS DRIVING OF THE SHAFT BY BOTH DRIVE MEANS, CAN TAKE PLACE ONLY MOMENTARILY WHEN, DURING DRIVING OF THE SHAFT BY THE DISTANCE DRIVE MEANS, THE VARYING SPEED OF THE SHAFT IS MOMENTARILY EQUAL TO THE CONSTANT SPEED AT WHICH THE TIME DRIVE MEANS DRIVES THE SHAFT.
