A dart board cabinet includes one or more reference line generating devices attached to the cabinet, to generate one or more reference lines or toe lines in front of a dart board, and to avoid the users or the players from drafting the toe lines manually, and from drafting the toe lines every time when the players are going to play the dart games. The reference line generating device includes a light generating device received in a housing and supported on a circuit board, and adjustable to various angular positions, for generating the toe lines. A lens may be disposed in front of the light generating device for generating the toe lines.
