| 摘要 |
<p>The present invention relates to an apparatus for detecting a magnetic pattern. The apparatus for detecting a magnetic pattern includes: a multi-channel magnetoscope which becomes magnetized by a division excitation signal of a channel corresponding to an excitation coil of each magnetic sensor; a signal synthesis unit which synthesizes multi-channel detection signals output from the detection coil of each magnetic sensor of the magnetoscope to output a time series detection signal of a single channel; and a magnetic pattern detection unit which detects a magnetic pattern of a medium having passed the magnetic detection unit based on the time series detection signal.</p> |
