  As shown in FIG. 1, the video display device 20 includes a liquid crystal display 21, a mirror member 22, and a lens member 23 installed on the back side of the game board 11. As shown in FIG. 2A, the game board 11 is provided with a rectangular opening 12 as viewed from the front, and upper and lower decorative members 13a and 13b are provided at the upper edge 12a and the lower edge 12b, respectively. Is provided. At a position facing the opening 12 from the front side of the game board 11, a transparent plate 14 whose upper and lower edges are supported by both decorative members 13 a and 13 b is provided so as to be parallel to the game board 11. A display support plate 24 is provided in a lower region of the opening 12 so as to be substantially perpendicular to the game board 11.

  A display fixture 25 is provided on the upper surface side of the display support plate 24, and the liquid crystal display 21 is fixed to the display fixture 25 so that the image display surface 21a faces upward. The mirror member 22 is made of a plane mirror, and the normal line of the reflecting surface 22a is located in a plane (vertical plane in FIG. 4) that is a vertical plane perpendicular to the game board 11 when the game board 11 is viewed from the front. As described above, the upper edge portion is supported by the upper decorative member 13a, and the lower edge portion is supported by the mirror support member 26 provided on the display fixture 25 so as to extend in the vertical direction. As a result, the reflecting surface 22a is in a state of facing diagonally both the player (front) and the liquid crystal display 21 (downward).

  A lens housing portion 27 is provided above the liquid crystal display 21, and the lens member 23 is provided in the lens housing portion 27 so that its main plane is parallel to the image display surface 21 a of the liquid crystal display 21. Yes. The lens member 23 is a biconvex (or plano-convex) cylindrical lens, and in the lens housing portion 27 so that the generatrix of the lens surface faces the lateral direction of the game board 11 (the direction perpendicular to the paper surface in FIG. 1). It is supported. Here, the distance from the main plane of the lens member 23 to the image display surface 21 a of the liquid crystal display 21 is longer than the focal length of the lens member 23. Therefore, an enlarged image P ″ Q ″ of the image PQ displayed on the image display surface 21a is displayed as an inverted real image above the lens member 23.

  When a player located on the front side of the game board 11 looks inside the pachinko machine 1 through the opening 12 opened in the game board 11 (a player's eye e is shown in FIG. 4), the field of view is The reflection image P′Q ′ of the image P ″ Q ″ projected above the lens member 23 by the mirror member 22 is displayed as shown in FIG. 4. Here, according to the optical properties of the plane mirror, the image of the object projected by the plane mirror is an isometric virtual image. That is, when the image P ″ Q ″ as an object is compared with the reflected image P′Q ′, the reflected image P′Q ′ has the same size in the vertical and horizontal directions as the image P ″ Q ″. However, since the image P ″ Q ″ is an image obtained by enlarging the vertical dimension of the image PQ as described above, if the horizontal dimension × vertical dimension of the image PQ is w × h as a result, the player's eyes The horizontal dimension × vertical dimension of the reflected image P′Q ′ reflected on the screen is w × H (H = h × β). Here, β is the magnification of the lens member 23, and β> 1.

  Here, like a conventional pachinko machine, the liquid crystal display 21 is arranged vertically (in parallel with the game board 11) and the image display surface 21a is within the player's field of view (the game board 11 shown in FIG. 1). In this pachinko machine 1, assuming that the viewing angle of the image (height h) that is likely to be visible in the field of view is θ, Although the reflected image P′Q ′ of the image PQ on the display surface 21 a appears to be located behind the mirror member 22, the viewing angle θ ′ of the reflected image P′Q ′ (height H) is determined from θ depending on the magnification α. Can also be increased (θ ′> θ). At this time, the player positioned on the front side of the game board 11 has an image in which the vertical dimension is enlarged in the visual field viewed through the opening 12 formed in the game board 11 than when the liquid crystal display 21 is placed vertically. You will see P'Q '.

  Thus, in the video display device according to the present embodiment, on the back side of the game board 11, the liquid crystal display 21 in which the image display surface 21 a is provided in a direction substantially orthogonal to the back side of the game board 11, and the front side of the game board 11 An enlarged reflected image for forming an enlarged reflected image P′Q ′ of the image PQ displayed on the image display surface 21 a of the liquid crystal display 21 in the field of view viewed through the opening 12 formed in the game board 11 by the player located in the game board 11 Forming means. Here, the enlarged reflection image forming means corresponds to the lens member 23 and the mirror member 22 in the present embodiment. In such a configuration, the enlargement magnification between the image on the image display surface 21a of the liquid crystal display 21 and the reflected image of the image formed by the enlarged reflected image forming means (the lens member 23 and the mirror member 22) is appropriate. By setting the value to a value, the vertical dimension is enlarged compared to the conventional case where the liquid crystal display 21 is provided in parallel with the game board 11 and the player directly views the image displayed on the image display surface 21a. It is possible to show it in a state. Therefore, according to the present video display device 20, it is possible to improve the interest given to the player by increasing the video size that the player actually sees without increasing the size of the expensive liquid crystal display 21. Alternatively, if the video size that the player actually sees is kept as it is, the size of the liquid crystal display 21 can be reduced, so that the cost (the cost required for manufacturing the liquid crystal display 21 and during the game) (Cost required to operate the liquid crystal display 21) can be reduced.

  The preferred embodiments of the present invention have been described so far, but the scope of the present invention is not limited to those shown in the above-described embodiments. For example, in the above-described embodiment, an image in which the vertical dimension of the image displayed on the image display surface 21a of the liquid crystal display 21 is enlarged with the image display surface 21a of the liquid crystal display 21 facing upward is seen by the player. However, the image in which the horizontal dimension of the image displayed on the image display surface 21a of the liquid crystal liquid crystal display 21 is enlarged with the image display surface 21a of the liquid crystal display 21 facing the left and right direction of the game board 11 is a game. It can also be reflected in the eyes of the person. That is, if the image display surface 21a is provided in a direction substantially orthogonal to the game board game board 11, the liquid crystal display 21 can be attached in any manner.

  In the above-described embodiment, the liquid crystal display 21 is provided such that the image display surface 21a is substantially perpendicular to the game board 11. However, the liquid crystal display 21 is in the eyes of the player due to the arrangement of the mirror member 22. As long as the image to be projected is substantially parallel to the game board 11, it is not necessarily perpendicular to the game board 11.

  Moreover, although the mirror member 22 in the above-mentioned embodiment was a plane mirror, the glass plate which can polish the surface and can use the surface as a reflective surface may be sufficient. The mirror member 22 is not necessarily limited to a plane mirror, and may be a concave cylindrical mirror having a concave reflecting surface or a convex cylindrical mirror having a convex reflecting surface. The lens member 23 is preferably a Fresnel lens. Thereby, the thickness of the lens member 23 can be reduced.

  In the above-described embodiment, the case where the gaming machine to which the present invention is applied is a pachinko machine has been described as an example, but the present invention is similarly applied to other gaming machines (for example, an arrange ball machine, a slot machine, etc.). It is possible to apply to.
