<p>PURPOSE:To grasp the lending destination, amount and item, etc., of a cloth- made product without fail by fitting a magnetic marker to the cloth-made product, passing it through an alternative current magnetic field and recognizing the pattern of a time sequential pulse voltage train to be generated at a detecting coil in that case. CONSTITUTION:This magnetic marker of the like has a rectangular magnetic histeresis characteristic and for the magnetic marker, plural magnetic fine wires or thin bands with the various levels of coercive force at least are parallelly and selectively arranged at desired intervals in a lengthwise direction. Then, the magnetic marker is fixed into a part sewing the edge part of a cloth- made product 2 fold once at least. Afterwards, the cloth-made product 2 is passed through the alternative current magnetic marker at that time is taken out of a detecting coil 7 and a signal processing is executed. Therefore, the amount and kind of the cloth-made product can be identified. Thus, the large amount of the cloth-made products such as informal cotton kimonos for summer wear or sheets, etc., can be handled and managed efficiently without requiring much labor.</p> |
