  • Magnetic sensor device
    Patent number: 9234947
    Abstract: By providing a first magnet and a second magnet on wall surfaces of a hollow section where paper money is conveyed such that different magnetic poles face each other, a gradient magnetic field is formed wherein both a magnetic field component in an opposing direction to the magnets and a magnetic field component in a conveyance direction of the paper money include a zero point. An AMR element is provided between the paper money and the first magnet. The AMR element is enclosed by a multi-layered substrate and covered with resin. The AMR element is provided in an area where the magnetic field intensity is weak, which is where the magnetic field intensity in the gradient magnetic field in the conveyance direction is near zero. The paper money passes through an area where the magnetic field intensity of the gradient magnetic field is strong.
