<P>PROBLEM TO BE SOLVED: To effectively prevent illegal opening of a board case that stores a control board of a game machine and to reliably detect the fact of illegal opening to minimize damage. <P>SOLUTION: A board case assembly (MCA) for storing the control board (MCB) of a slot machine is adapted to undetachably engage a case cover (300) with a case base body (200) through connecting members (400) and to arrange connectors for connection with external equipment on the side of opposite sides of square cylinder openings (310) which engage case members with each other and to which a mark of opening is left. Consequently, there is no risk of harness connected to the connectors being overlapped with the square cylinder openings to ensure finding of illegal opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
