SOLUTION: The substrate case 1 is built in a game machine for storing at least a substrate 5 for controlling the game machine, etc. The substrate case 1 comprises a substrate base part 2 fixed to the game machine and a substrate case cover part 3 fixed to the substrate base part 2 to cover the substrate base part 2. The substrate base part 2 has the setting changing part 7 for changing the probability of a lottery for various elected hands in a game. The substrate case cover part 3 has a through part 32 permitting operation of the setting changing part 7 from the front side, and a through part cover part 31 for opening/closing the through part 32.
