Abstract

PURPOSE: To provide a clear easily readable indication by moving the pointer of a meter and indicating the speed of the automobile until a position signal for the pointer of the meter coincides with a signal proportional to the speed of the automobile.
CONSTITUTION: Suppose the pointer of the meter 4 is at an illustrated position. The level of pattern electrodes 3a, 3b, 3c and 3d of the pattern electrode part 3 is "H" and the level of the pattern electrode 3e "L". These represent that the speed of automibile is 15km/h. Binary coded signals transmitted from this pattern electrodes 3 are outputted to digital comparator 5. In the meantime, binary coded signals correcponding to the speed of automobile are sent to digital comparator 5 by the pulse signal corresponding to the speed of automobile that is transmitted from the speed sensor 1. As a result, both data are compared. If they agree to each other, there is no output from the digital comparator 5 and a differential circuit 6 is at a standstill. In addition, the drive part 7 has stopped and the pointer of the meter 4 is in a state of nonoperation. In other whords, this means that the automobile speed is 15km/h.
