Abstract
A card reader may include a transport path; a housing; a magnetic head to read the magnetic information at a reading position of the transport; and a first inductive proximity sensor. The first inductive proximity sensor may include a first oscillation circuit; and first and second detection coils connected in parallel to the first oscillation circuit. The magnetic head may be accessible to the magnetic card from a first side of the transport path in a first direction perpendicular to a transport face of the magnetic card. Coil center lines of the first and second detection coils may extend in the first direction on the first side of the transport path. The first and second detection coils may be disposed adjacent to each other in the transport direction and structured to generate magnetic fields in opposite directions in the first direction when the first inductive proximity sensor is driven.
