<P>PROBLEM TO BE SOLVED: To provide a sealing cap where the use of a sealing cap removed from another board case can be discriminated easily and clearly. <P>SOLUTION: An association marking group 55C is adopted, where it includes characters, symbols, figures or patterns, and the like, and is in a mode differing from that of a main board case 50 included in another slot machine 1 of the same type. The association marking group 55C is marked over a boundary surface 75A of a shade-shaped lid part 72 and a surface 56 of a body part 51. An original sealing cap 70 is broken and removed from the body part 51 and the non-original sealing cap 70 removed from another main board case 50 is fitted to the main board case 50, thus preventing the association marking group 55C, which is not original, from matching the association marking group 55C at a side of the body part 51, and hence discriminating a fraudulent act easily and clearly and effectively preventing the fraudulent act. <P>COPYRIGHT: (C)2013,JPO&INPIT |
