摘要：
The device according to the present invention comprises: transmitting lines having folded-back forms for feeding current to generate magnetic fields; and receiving lines having folded-back forms and disposed in a position where the receiving lines can be electromagnetically connected to the transmitting lines for detecting changes in magnetic fluxes which are changed by an approaching metal member. A plurality of the said transmitting lines are arranged on one and the same plane and also a plurality of the said receiving lines are arranged on one and the same plane. These transmitting lines and receiving lines are surface-parallel to each other and arranged in directions intersecting each other, to thereby form a sensing matrix. This sensing matrix is opposed to the surface of a board, along which a metal member to be detected moves, with a space, through which at least the metal member can pass, held therebetween, and transmitting means and receiving means are connected to this sensing matrix, thereby detecting the position of presence of the metal member.
