<p><P>PROBLEM TO BE SOLVED: To provide a game machine by which a fraudulent action to the game machine can be found out and prevented. <P>SOLUTION: A discriminating seal LB having a holding layer where many fine glass beads arranged in lines are embedded while partially exposed, a printing layer printed on the side of a face where many glass beads are exposed, and a reflecting layer arranged on the side of a holding layer and reflecting irradiation light of a predetermined wavelength irradiated from the side of the face where the many glass beads are exposed is affixed so as to straddle on a connecting face of the first connecting part 2b formed in the first base plate case B and the second connecting part 3hb formed in the second base plate case C. The fraudulent action can be found out and prevented by searching the presence or absence of the generation of a specific optical pattern when irradiating the discriminating seal LB with the irradiation light of the predetermined wavelength. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
