Abstract
The reference voltage of the rotation detecting comparator is set to the constant voltage circuit used in another circuit. However, because the constant voltage circuit used in another circuit has a constant voltage value suitable for its original purpose, a voltage is inputted to the rotation detecting comparator from an arbitrary location of a resistant element which is connected in series to a coil that affects a value of the rotation VRS and the non-rotation VRS. With this structure, a voltage value to be detected which is inputted to the rotation detecting comparator can be lowered as much as the resistant ratio with the voltage of the VRS per se being not changed, so that rotation or non-rotation can be detected even by the reference voltage of the constant voltage circuit which is used in another circuit.
