In a state where a main control board unit 400A having the main control board and a sub control board unit 500A having the sub control board are attached to a slot machine, a sub control board unit 500A is made to partially cover the main control board unit 400A, and thus, the main control board unit 400A cannot be detached unless the sub control board unit 500A is detached first. |
