  • Patent number: 9664533
    Abstract: A magnetic field generator disposed on one surface side of a sheet-shaped object-to-be-detected contains a magnetic component. The magnetic field generator includes a first magnetic pole part that forms a first magnetic pole, and a second magnetic pole part that forms a second magnetic pole with reverse polarity of the first magnetic pole. The magnetic field generator generates a cross magnetic field that crosses the object-to-be-detected. An MR element is disposed between the first magnetic pole part and the object-to-be-detected. The resistance value of the MR element changes according to a change in a component of the cross magnetic field in a conveying direction. The position of the MR element in the conveying direction is position shifted along the conveying direction from the center position of the first magnetic pole part in the conveying direction, and located between both ends of the first magnetic pole part in the conveying direction.

  • Patent number: 9444952
    Abstract: A magnet is disposed on one side of a conveyance plane in which a sheet-like medium to be read is conveyed and generates a magnetic field in a direction perpendicular to the conveyance plane. A magnetoresistive effect element is disposed between the magnet and the conveyance plane, and detects an intensity variation in a conveyance direction component of the magnetic field in a magnetic reading area. An imaging optical system and a light receiver are disposed on the side opposite to the magnet side with respect to the conveyance plane. The imaging optical system forms an image of an optical reading area on the light receiver, the optical reading area including at least a portion in the conveyance direction of the magnetic reading area of the conveyance plane.

  • Patent number: 9244135
    Abstract: A magnetic sensor device includes a first magnet and a second magnet that are disposed on mutually opposing sides of a conveyance path, and one of poles of the first magnet faces an opposite pole of the second magnet. The first magnet and the second magnet generate a cross magnetic field whose strength in a spacing direction, which is orthogonal to a conveying direction, is within a predetermined range. An AMR element is located in a magnetic field in which the strength of the cross magnetic field in the spacing direction is within a predetermined range, and detects, as change in a resistance value, change in the cross magnetic field caused by an object to be detected. A multilayer board outputs the change in the resistance value detected by the AMR element to a processing circuit.

  • 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.

  • Publication number: 20140376254
    Abstract: A light guide propagates light emitted by a light source in the long axis direction. A fluorescent material layer surrounds the outer periphery of the light guide except for an opening along the long axis direction. A light reflecting pattern is provided on the outer periphery of the light guide opposite to the fluorescent material layer. The fluorescent material layer captures light reflected by the light reflecting pattern and exiting from the outer periphery of the light guide, reflects part of the light, and emits light of different wavelengths. The light emitted by the fluorescent material layer is transmitted into the light guide, and the light having entered therein from the end and the light emitted by the fluorescent material layer are emitted to the object from a portion of the light guide that is exposed in the opening.
