PURPOSE:To fit a convex lens on the surface side of the liquid crystal panel face of a slot machine so that three picture frames displayed on the liquid crystal panel face can be seen through to be circularly rotated into a drum shape. CONSTITUTION:In a slot machine projecting three picture frames 2a, 2b, 2c having various pictures respectively on a plane liquid crystal panel face 3 for a slot game, a convex lens 4 is fitted on the surface of the liquid crystal panel face 3 corresponding to three picture frames 2a, 2b, 2c so that the picture frames 2a, 2b, 2c are seen to be circularly rotated into a drum shape. The lens 4 may be divided into three to be fitted on the surface side of the picture frames 2a, 2b, 2c, respectively, or the lens 4 may be formed into a convex shape or a concave shape over the surface side of all the picture frames 2a, 2b, 2c, or a Fresnel lens may be used in place of the convex lens. |
