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.
