<p><P>PROBLEM TO BE SOLVED: To provide a game token having identification information, which does not reduce identification function due to wear and is always reliably detected using a conduction sensor. <P>SOLUTION: A disc-shaped token 1 made of a conductive metallic material has a through hole 2 or a recess 5. An identification function member 3 having a non-conductive surface 3a and having identification information is disposed in the through hole or the recess. The surface of the identification function member is formed to be recessed lower than an opening edge 2a, 5a of the through hole or the recess so that when an outer peripheral edge of a token 1' of the same shape is brought into contact with the opening edge 2a, 5a of the through hole or the recess, the outer peripheral edge 1a of the token 1' will always separate from the surface 3a of the identification function member 3 regardless of the direction of contact. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
