| description | The magnetic sensor in the invention is arranged to detect a change of magnetic field caused by a movement of the magnetic movable by a magnetic sensor element arranged with a gap to the magnetic movable, to convert the detected change of magnetic field by first and second bridge circuits into electric signals, to generate first and second rectangular-wave signals by first and second comparator circuits depending upon the electric signals, and to form a signal having at least four levels by a signal forming circuit, thereby detecting a moving direction of the magnetic movable depending upon a level-change order in the signal. This makes it possible to detect a rotating direction of the magnetic movable rapidly and correctly. |
