A magnetic circuit, provided with a short magnet (1a) and short magnet (1b) that are arranged in an array, and a yoke (2a) and a yoke (2b) provided so as to sandwich the short magnet (1a) and short magnet (1b). The short magnet (1a) and short magnet (1b), are arranged so, that have a space between them that is a predetermined gap (3) or less in the arrangement direction of the array respectively. In addition, the short magnet (1a) and short magnet (1b) are arranged so that one magnetic pole is located on the side toward one of the pair of yokes (2a) and (2b), and the other magnetic pole is located on the side toward the other yoke.
摘要:
A magnetic field generator is disposed on one surface side of a sheet-shaped object-to-be-detected (4) and 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 that has a reverse polarity of the first magnetic pole. The magnetic field generator generates a cross magnetic field that crosses the object-to-be-detected (4). An MR element (3) is disposed between the first magnetic pole part and the object-to-be-detected (4). The resistance value of the MR element (3) changes according to a change in a component of the cross magnetic field in a conveying direction. The position of the MR element (3) in the conveying direction is a 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.

A magnetic sensor device comprises a first magnet (6) and a second magnet (7) that are disposed on mutually opposing sides of a conveyance path (2), and one of poles of the first magnet (6) faces an opposite pole of the second magnet (7). The first magnet (6) and the second magnet (7) 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 (10) 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 a change in a resistance value, a change in the cross magnetic field caused by an object (5) to be detected. A multilayer board (9) outputs the change in the resistance value detected by the AMR element (10) to a processing circuit (15).
