ートからなるマグネツト検出回路。 An amplifier that amplifies the electromotive force induced in the coil by changing the magnetic flux created by the magnet and the linkage number of the coil, two comparators that compare and select only the positive or negative voltage of the amplified electromotive force, and a comparator. A magnet detection circuit consisting of a multivibrator that controls the pulse width of the signal selected by the magnet, and an AND gate that multiplies the output signal from the multivibrator and the output signal from the comparator.
