Abstract
In a magnetic detection apparatus, a magnetic detection sensor generates a sensor output signal whose high level and low level have different potentials in accordance with the moving direction of a magnetic moving object, and a computer unit includes three comparator circuits and detects the output signal of the magnetic detection sensor with three levels of comparison threshold values, so that the moving direction of the magnetic moving object can be detected accurately without any delay.
