<P>PROBLEM TO BE SOLVED: To provide a Pachinko slot machine preventing a fraud by use of a special device (a special wire) for the fraud. <P>SOLUTION: An intrusion prevention member 170 is mounted at a prescribed position of an opening part of a sub relay board case for closing the upper half part of the opening part. Even when a third person committing a fraud tries to insert the special wire T for fraud, via the opening, into a position of a sub relay board 100 that is disposed inside the sub relay board case, a plate portion 183 of a first plate part 180 forming the intrusion prevention member 170 surely prevents the intrusion of the special wire T. <P>COPYRIGHT: (C)2013,JPO&INPIT |
