摘要： A magnetic sensor device includes: a magnetic field generator, disposed at one surface side of a sheet-like to-be-detected object including a magnetic component, to generate an intersecting magnetic field intersecting the object; and a magnetoresistive effect element disposed between the object and the magnetic field generator, having a resistance value changing in accordance with change of a component of the intersecting magnetic field in a conveyance direction along which the object is conveyed, when the object is conveyed. The magnetoresistive effect element includes resistive elements adjacent to each other in the conveyance direction and interconnected by a bridge, disposed in linear symmetry relative to an axis perpendicular to the conveyance direction and extending through a center of the bridge. A position in the conveyance direction of the bridge center of the magnetoresistive effect element coincides with a position in the conveyance direction of the magnetic field generator center.

摘要： A magnet is disposed on one face of a hollow section which is the conveyance path of an object of detection, and has a magnetic pole of designated length along the conveyance direction of the object of detection. A magnetic body is disposed along the conveyance direction opposite the magnet with the hollow section therebetween, and generates a cross magnetic field that crosses the hollow section formed between the magnetic body and the magnet. An anisotropic magnetoresistance element is disposed on the side of the magnetic body carrier facing the hollow section, and has magneto-sensing action in the conveyance direction.

摘要： A magnetic sensor device includes: a magnet; a magnetic-resistance-effect-element mounted substrate on which a magnetic-resistance-effect-element mounted body is mounted on a surface thereof opposite to a surface thereof facing the magnet, the magnetic-resistance-effect-element mounted body extending in the longitudinal direction of the magnet; a case that accommodates or retains the magnet and the magnetic-resistance-effect-element mounted substrate; and a magnetic shield that covers the case except for the surface of the magnetic-resistance-effect-element mounted substrate on which is mounted the magnetic-resistance-effect-element mounted body. The magnetic shield covers the case at a position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet, or from the position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet to a side of the case opposite to the magnet.

摘要： 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.

摘要： A first magnetic field generator generates a magnetic field intersecting a detection object being transported along a transport path. A second magnetic field generator opposite to the first magnetic field generator with respect to the transport path generates a magnetic field intersecting the detection object. A first magnetoresistive element between the first magnetic field generator and the transport path outputs, as a change in resistance, a change in magnetic flux density produced by transport of the detection object. The first and second magnetic field generators are different in a magnetic pole facing the transport path and are arranged with a center of the first magnetic field generator in a transport direction of the detection object and a center of the second magnetic field generator in the transport direction are located at mutually different positions. The first magnetoresistive element includes a first resistor and a second resistor arranged with spacing therebetween.
