SOLUTION: A half mirror 2 is installed inside the housing 7 of a game machine main body while being tilted by 45 deg., and a display light beam produced by a liquid-crystal display 1 is reflected by the half mirror 2 and allowed to advance to the depth of a game board. A concave mirror 3 is mounted in the depth of the game board to reflect and collect the advancing display light beam. The display light beam reflected by the concave mirror 3 is transmitted through the half mirror 2 and emitted to the front surface of the game board 5 to form a real image 4 at a position which it reaches after going out from the game board 5. The viewing point 6 of a player exists ahead of the real image 4, and since the display light beam appears to go out from the real image 4 as seen from the player, the player feels that the display light beam is present in front of the game board 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device used for various game machines, for example, a board-type game machine such as a bin ball or a pachinko machine at a game center.

[0002]

2. Description of the Related Art Conventionally, there has been known an apparatus in which a display is incorporated in a game machine, and an image having a game property is displayed on the game machine to double the fun of the machine. For example, an image of a throttle machine appears on a display in response to the rolling of a ball on a board, and the image starts to move. In recent years, display screens have become larger and images have become more versatile than conventional game machines.

Further, very recently, a three-dimensional (3D) display device in which a lenticular lens is arranged on a screen and a three-dimensional image can be viewed from a player has appeared. This display has the effect of exciting the player by providing a powerful image.

[0004]

However, a 3D display device capable of expressing a more powerful image than a conventional liquid crystal display device incorporated on a panel has a disadvantage in that, in principle, the display can be visually recognized in 3D. Must be within a limited range of the player's viewpoint (specifically, a grid defined opposition), and for the player, the viewpoint must be fixed there. This has a problem that a sense of fatigue accompanies since the user must always care about stereoscopic vision and maintain a posture in accordance with the appearance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a display device for a gaming machine which allows a player to enjoy a powerful game in a comfortable posture.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a display for displaying an image related to the contents of a game in a game machine body having a board, and a display device for reflecting display light emitted from the display. A display device for amusement machines, comprising an optical system including a half mirror for transmitting / transmitting light and a curved mirror for condensing light reflected / transmitted by the half mirror. It is characterized in that the real image is present near the board surface of the amusement machine or at a position after being emitted from the board surface.

That is, the present invention employs an optical system for forming a real image on the player's viewpoint side from the board of the game machine in order to provide a powerful display screen.

Here, the curved mirror is a curved mirror for condensing display light emitted from the display. The curvature of the curved mirror depends on the size of the display.
It is determined so that a real image is formed at a position of 50 to 550 mm.
In amusement machines such as ordinary panda machines, for example, 100 to 2
It is preferable to use one having a curvature of 50 mm. Further, the curved mirror is preferably arranged substantially perpendicularly or substantially parallel to the board surface of the game machine, but is appropriately determined in combination with the half mirror.

The half mirror bends either the optical axis of the incident light from the display or the optical axis of the outgoing light, and is disposed between the board of the game machine and the curved mirror. The preferred location of the half mirror is approximately the focal point of the curved mirror, and the inclination angle is preferably 45 ° with respect to the optical axis. However, the installation angle of the half mirror is appropriately changed according to the arrangement of the display and the curved mirror.

As a display, for example, a CRT, a liquid crystal display, a plasma display or the like can be used. When a liquid crystal display or the like is used, a halogen bulb, a cold cathode tube, or an LED can be used as a backlight light source. . The location of the display is not particularly limited, and in the present invention, the reflection mirror may be provided at a position opposite to the display and at a tilt angle from the optical axis of the display. As a result, it is possible to view the image on the display unit in addition to the player. The tilt angle is not particularly limited, but is about 10 ° to 20 ° from the optical axis direction.
It is preferable to dispose it at an inclined position.

The reflecting mirror may be disposed at a position having an angle from the optical axis of the light emitted from the half mirror, for example, at a position inclined by about 10 to 25 ° from the direction of the optical axis of the emitted light.
In this case, the reflecting surface of the reflecting mirror may be made up of a plurality of surfaces. This makes it possible to look into the display surface of the display from multiple directions.

In the present invention, the term "position near the board of the game machine or after the light is emitted from the board" means a position from the game machine main body to the player's viewpoint, and is preferably in front of the aforementioned game machine. And 450 in front of the player
５550 mm.

Incidentally, the display device for amusement machines of the present invention can be used for all types of amusement machines such as bin balls and pachinko machines.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A display device for a game machine according to the present invention will be schematically described with reference to the drawings. FIG. 1 shows a cross section of the configuration of the present invention. Reference numeral 1 denotes a liquid crystal display, which comprises a backlight tube 1a, a light guide plate 1b, an LCD 1c, a case 1d, and the like, on which various images corresponding to the contents of the game are displayed. The liquid crystal display 1 is attached to a lower surface of a housing 7 of the main body of the game machine.
The display light generated by the liquid crystal display 1 is emitted from the lower opening of the LCD. A board surface 5 is attached to an end of the housing 7, and this board surface 5 is a play surface with nails in a pachinko machine, for example, and the play mechanism itself is omitted.

Further, inside the housing 7, a half mirror 2 is installed inclined at 45 °, and the display light generated by the liquid crystal display 1 is reflected by the half mirror 2, and the half mirror 2 shown in FIG. Proceed to the left (back side of the board). A concave mirror 3 is attached to the back side of the panel, and the display light that has advanced is reflected and collected. The display light reflected by the concave mirror 3 passes through the half mirror 2 and is emitted to the front of the board 5, and forms a real image 4 at a position after the emission from the board 5. Beyond that is the player's viewpoint 6,
When viewed from the player, the display light has an illusion that the display light is emitted from the real image 4, and therefore, it is felt that the display light exists on the near side of the board surface 5.

A flat mirror (or a mirror having a gentle convex surface) 8 is attached to a portion of the housing 7 facing the liquid crystal display 1. The display light reflected by the mirror 8 is reflected by the half mirror 2 and is emitted upward out of the board surface 5. As a result, other customers and clerks looking over the player's head can understand the content of the game,
Players will be even more excited.

If the clerk needs to look further in from above, a method of directly viewing the liquid crystal display 1 is also possible.

In the above embodiment, the liquid crystal display 1
And the plane mirror 8 may be arranged upside down. Further, the liquid crystal display 1 may be arranged on left and right wall surfaces. In such a case, it goes without saying that the half mirror 2 is mounted according to its orientation. Further, the Hawa mirror 2 does not necessarily need to be set at 45 °, and the angle may be slightly changed according to the arrangement form.

FIG. 2 shows a simple positional relationship of the optical system in the apparatus shown in FIG. 1 are given the same numbers. Assuming that the liquid crystal display 1 is an arrow pointing upward of the optical axis p, the light emitted from the tip of the arrow reflects at the center of the concave mirror 3 and reflects at the same angle as the optical axis. On the other hand, the light passing through the focal point of the concave mirror 3 becomes parallel to the optical axis p after reflection. The light reaching the concave mirror 3 in parallel to the optical axis p passes through the focal point after reflection. As a result, a real image 4 is formed at a position where light converges again. In addition, 1 'shows the virtual image of a liquid crystal display.

Now, the size of the liquid crystal display is 2.8 "(71.1 diagonal).
mm), the focal length of concave mirror 3 is 80 mm (spherical mirror with curvature of R = 160 mm), and the position of liquid crystal is 129.8 mm from concave mirror 3, 4.5 ″ (diagonal 114.20 mm) at position 208.6 mm from concave mirror 3. 3m
m) will appear. Therefore, the half mirror 2 is set to 45 so that the reflection point of the optical axis is almost at the focal point.
By arranging at an angle of ゜, even if the board surface is at a position 150 mm from the concave mirror 3, it can be present without difficulty.

FIG. 3 shows another embodiment of the present invention. FIG.
(A) is a sectional configuration view, in which 11 is a liquid crystal display, 33 is a concave mirror, and the liquid crystal display 11 and the concave mirror 33 are arranged so as to face each other in the housing 77. The half mirror 22 exists between the liquid crystal display 11 and the concave mirror 33. On the other hand, a mirror 88 is inclined at the back opposite to the board surface 55, and the display light reflected by the mirror 88 travels upward from the exit window. As a result, the image can be viewed over the player 6's head. Further, the mirror 88 is divided into three parts, and as shown in FIG. 3B, display light can be emitted to the lower part 88a upward, the left part 885 to the right, and the right part 88r to the left. By doing so, you will be able to see the game contents from the left and right,
Customers who come with the players can also enjoy together.

Further, when a glass plate is incorporated in front of the board due to the feature that a real image appears before the board,
When a diffusion surface is provided on the glass surface by vapor deposition or pasting, a real image can be created here, and thus a display device of a new image can be provided. In addition, it is more effective to make the image more clear by finishing the peripheral surface of the board where the display image appears in dark black.

[0023]

According to the present invention, the optical system in the game machine is an optical system of a coaxial system, so that there is little optical distortion, and since it is a reflection optical system, it is an excellent optical system with no color shift. A real image can be formed where the player approaches the viewpoint. As a result, the projected image can be seen by the player, and a powerful game can be enjoyed. Also, other customers and clerks looking over the player's head can easily understand the contents of the game.
