Abstract
A speed meter unit has a magnetic pointer position detector, including an output coil, a detection coil and a magnetic piece. The output coil generates magnetic flux. The detection coil is for detecting the magnetic flux from the output coil. When a pointer has returned to an initial position, the magnetic flux generated in the output coil can reach the detection coil through the magnetic piece, so that a microcomputer can detect the initial position of the pointer. Such the magnetic pointer position detector is resistive to the soil or the oxidization, so that the speed meter unit can detect the initial position of the pointer accurately and securely.
