摘要： The present invention provides for a metallic surface identifying sensor including: a magnetic pole portion for detection which shifts facing a surface of a magnetic body to be identified having an uneven shape wherein the distance from the surface to be identified changes along with the uneven shape while shifting; a reference magnetic pole portion which is placed across from a reference surface, wherein the distance from the reference surface to the magnetic pole portion is maintained approximately constant regardless of the shifting of the magnetic pole portion for detection in relation with the surface to be identified; magnetizing coils which are separately wound around the magnetic pole portion for detection and the reference magnetic pole portion to generate magnetic fluxes; and detecting coils which are separately wound around the magnetic pole portion for detection and the reference magnetic pole portion to detect the magnetic fluxes wherein the uneven shape of the surface to be identified of the metallic body is detected based on detection outputs from the magnetic pole portion. The present invention also provides for a differential magnetism sensor apparatus, a coin identifying apparatus, a magnetic sensor body, a coin identifying sensor, a displacement sensor and a proximity sensor.

摘要： A displacement sensor for sensing the relative position of an object to be detcted is provided. The displacement sensor includes a core body having a core center portion and core end portions that are continuously formed on both sides of the core center portion. Magnetizing coils and detecting coils are wound around the core body such that they are lined on an axis of the core body. One of the magnetizing coils and detecting coils is placed at the core center portion while the other ones of the magnetizing coils and detctin coils are placed at the core end portions in the axial direction. The width of the core end portions in the direction perpendicular to the axial direction of the core body is substantially the same and is smaller than the width of the core center portion.
