PROBLEM TO BE SOLVED: To provide a game machine capable of reliably grasping at an early stage a dishonest behavior relating to a control board in the game machine comprising a board box.SOLUTION: The board box mounted to a pachinko machine 10 comprises: coupling means which couples a box base for housing a main controller with a box cover for covering the opening of the box base to seal the control board; sealing means for sealing the control board again after the sealed state of the board box by the coupling means is cancelled; and a joint portion to be coupled with a coupling metal fitting mounted to a game machine body. The coupling means is so provided to be nondetachable from the box base and the box cover. When the box base and the box cover are coupled with each other using the coupling means, the coupled state becomes non-cancellable. Removing a section including the joint portion, in the board box, from the board box cancels the sealed state of the board box obtained by the coupling means. |
