摘要:
A magnetic motion sensor has: two magnetic sensors aligned in a direction along which changes in a magnetic field shift for detecting an appearance of the changes; a differential means for taking out a differential signal of output signals from these two magnetic sensors; and a timing detection means for generating a pulse, indicating a timing at which the changes in a magnetic field pass through either of the magnetic sensors, when an output signal of the magnetic sensor in question strides over a threshold value, while generating a pulse, indicating a timing at which the changes in a magnetic field pass through in between the magnetic sensors, when the differential signal strides over the threshold value.
