PROBLEM TO BE SOLVED: To provide a control board assembly for the game machines which enables the easier and sufficient visual inspection of the control board housed in the board case having an inspection seal. SOLUTION: A transparent case cover (300) where the main control board (100) of a slot machine (SM) is housed is so arranged that one end of a flexible sheet member (400) with the inspection seal (450) sticking on it is welded on it. The rolling up of the sheet member with the welded part as base end enables the visual inspection of the entire surface condition of the main control board through the case cover.
