PURPOSE: A necklace-shaped ID tag is provided to prevent two connection wires from mutual interference during extraction since the two connection wires are reeled in each insertion groove formed on the surface of a winding reel. CONSTITUTION: A winding reel case(212) comprises an attaching/detaching protrusion, which has the shape and size corresponding to an attaching/detaching groove formed on the rear side of a card case, on the rear side thereof. A winding reel(218) is installed inside the winding reel to be rotatable and is formed with two connection wire insertion grooves on the side thereof. A coil spring(220) is inserted into a space formed in the winding reel and generates the reCONSTITUTION torque of a winding reel. Two connection wires(222) are reeled in the connection wire insertion groove of the winding reel, and the end thereof is connected to a neck wire connecting member placed on the upper part of the winding reel case. A guide member(224) is fixed to the top inside the winding reel case, and two through-holes for two connection wires are formed thereon. |
