Therefore, if the window frame part is formed in a tapered shape, the display window The effective area is reduced, and the liquid crystal display means is correspondingly reduced. On the other hand, if the upper and lower walls and the left and right walls of the window frame are parallel, the area of the display window can be secured widely, but the opening area on the front end side of the window frame is the same as the size of the display window. The front end side of the liquid crystal display means restricts the viewing area of the liquid crystal display means, so that the effective area of the liquid crystal display means is substantially reduced.

  Furthermore, even if the liquid crystal display means is enlarged, the liquid crystal display means is incorporated in a protective case, and the liquid crystal display means is mounted in correspondence with the window frame part that protrudes backward from the game board. The case will greatly protrude rearward from the back side of the game board, and problems such as interference of the protective case with other components arranged or mounted on the back side of the gaming machine main body also occur.

  In view of such a conventional problem, the present invention can use a large display panel, can prevent a limitation of the field of view due to a decorative frame or the like on the front side of the game board, and the player realizes an increase in the size of the display panel. Further, it is an object of the present invention to provide a gaming machine that can prevent an increase in the size of the protective cover on the back side of the gaming board.

The present invention, on the front surface of the game board, fitted with a decorative frame having a display window, the back side of the game board, a display panel corresponding to the display window, the driver board for driving the display panel in the gaming machine having a display hand stage including bets, the picture frame is a window in which the game board of fitted from the front side to the open mouth to an intermediate thickness of the game board and rear end becomes the display window a frame portion, wherein and a game board having a thickness of which intermediate in mounted on a rear end portion of the window frame portion and the display transparent window plate which closes the window, sheet metal of the display panel is fitted from the front side The fixing plate is bent from the middle in the thickness direction of the display panel to the outside and fixed to the back surface of the game board and a predetermined surface between the back surface of the display panel.
