<p>PURPOSE:To obtain an inexpensive and convenient data card enhanced in maintenance and usability widely by forming a plurality of conductive lands having different resistance values on an insulating card. CONSTITUTION:The conductive wires 3 connected to a large number of the detection terminals 2, which are provided to the surface of a data card 1 along one side thereof at an appropriate interval, at one ends thereof are composed of two kinds of ones having small and large widths and the small width conductive wires 3 have a high resistance value while the large width conductive wires 3 have a low resistance value and the data card 1 is discriminated by the combination of the small and large width conductive wires 3. A common terminal 5 is provided to one end of the common land 4 connected to the conductive wires 3 on the other sides thereof in common. These detection terminals 2, conductive wires 3, common land 4 and command terminal 5 are formed, for example, by printing conductive ink or paste in a predetermined pattern, and the conductive wires 3 and the common land 4 are covered with an insulating sheet or material 6 excepting the detection terminals 2 and the common terminal 5.</p> |
