Abstract

During a slot machine game, game effects are also displayed on a liquid crystal panel 39 d provided in a reel display window unit 39, and thus the liquid crystal panel 39 d serves as a new machine component for performing game effects. Therefore, new effects for the game can be performed on the liquid crystal panel 39 d, which facilitates maintaining the novelty of game effects. Furthermore, since the reel glass base 39 b is black-colored, any light incident on the reel glass base 39 b is not easy to be reflected on the liquid crystal panel 39 d. Consequently no light incident on the reel glass base 39 b is mirrored into the liquid crystal panel 39 d.
