GAME MACHINE

To provide a game machine capable of preventing a fraud to be executed to a connection part between a cable and a board.SOLUTION: A protective wall part (a protective wall part 335) provided in a board case (a main control board case 55) of the game machine according to the present invention, has a substantially rectangular shape and faces a cable-side connection part (a cable-side connection part 331a) of a connector (an optical connector 331). The length of a first side of a surface facing the cable-side connection part, of the protective wall part is longer than the thickness of the board, and the length of a second side that is longer than the first side of the surface facing the cable-side connection part, of the protective wall part, is longer than the cable-side connection part. The height of the protective wall part projecting from a board attachment part of the board case is higher than the board in a state of being attached to the board attachment part.SELECTED DRAWING: Figure 30 【課題】ケーブルと基板との接続部に対しする不正行為を防ぐことができる遊技機を提供する。【解決手段】本発明の遊技機の基板ケース（主制御基板ケース５５）に設けられた防壁部（防壁部３３５）は、略矩形であり、コネクタ（光コネクタ３３１）のケーブル側接続部（ケーブル側接続部３３１ａ）に対向する。防壁部のケーブル側接続部に対向する面の第一の辺の長さは、基板の厚みよりも長く、防壁部のケーブル側接続部に対向する面の第一の辺よりも長い第二の辺の長さは、ケーブル側接続部よりも長い。基板ケースの基板取付部から突出する防壁部の高さは、基板取付部に取り付けられた状態の基板よりも高い。【選択図】図３０
