Abstract

PROBLEM TO BE SOLVED: To make a virtual image of display exist in the farthest part and to make an area up to nearly a board surface expressed through a software technology, so that a larger feeling of stereoscopy is obtained. SOLUTION: In a housing 5, a curved-surface mirror 2 is installed opposite to a liquid crystal display unit 1. The curved-surface mirror 2 is a mirror in an aspherical toric shape and servers as a convex lens while reflecting light to generate a virtual image at a distance (farthest from the board surface). This virtual image is enlarged by the curved-surface mirror 2, so a larger field angle than the original display can be obtained. Consequently, the liquid crystal display unit 1 displays a large distance virtual image.

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, in a game such as a smart ball or a pachinko machine, an image of a slot machine appears on a display according to the rolling of the ball on the board, and some of the games can be enjoyed at the same time. In recent years, the display of this part has made the game more enjoyable due to the enlargement of the screen and the pseudo three-dimensional structure by improving the display software technique.

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, when a three-dimensional effect based on the software technique is used, the display is expressed from the position where the display actually exists to the vicinity of the board, and the degree of three-dimensionality is too large. Absent. In addition, stereoscopic vision using a lenticular lens requires attention from only a specific range due to its nature, and is not endurable for a long time. At the same time, due to its structure, there is also a problem that a fine display is impossible.

[0005] Therefore, the present invention provides a virtual image of a display in the back so that a large three-dimensional effect can be obtained, and uses a software technique.
An object is to express a region up to near the board surface.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a display for displaying an image relating to the contents of a game in a main body of a game machine having a board, and a display device for collecting display light emitted from the display. A display for a game machine provided with an optical system having a curved mirror that emits light, wherein the optical system causes a virtual image of the display device to be present near a board surface of the game machine or at a position deeper than the board surface. .

Here, the curved mirror is a mirror having an aspherical trick shape, and at the same time, serves as a convex lens while being reflected, condenses, and generates a virtual image at a distance. Although the curvature of the curved mirror depends on the size of the display, when the distance from the player's eyes to the board is set to 500 to 600 mm, it is determined so that a virtual image is formed at a position of 800 to 1000 mm from the eyes. It is preferable to use a game machine such as a normal pachinko machine having a curvature of, for example, 300 to 350 mm. It is preferable that the curved mirror is disposed to face the display, but it is appropriately determined in combination with the display.

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 installation location of the display is not particularly limited.

In the present invention, a flat mirror may be provided near the display so that the contents of the display can be seen by persons other than the player. The plane mirror is disposed at a position inclined from the optical axis from the display to the curved mirror.

In the present invention, "a position near the board of the game machine or at a position deeper than the board" means a position on the back side of the main body (opposite to the player) from the board of the game machine, and preferably as described above. If the distance from the player's eyes to the board is set at 500-600 mm,
This is a position of 1000 mm. Incidentally, the display device for amusement machines of the present invention can be used for all kinds of amusement machines such as binball and pachinko.

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 includes a backlight tube, a light guide plate, an LCD, a control circuit, a case, and the like, and displays various images according to the game content. The liquid crystal display 1 is attached to the lower side surface of the housing 5 of the game machine body at an angle of about 45 °, and the liquid crystal display 1 is opened through the lower opening of the housing 5.
The display light generated in step is emitted. A board surface 3 is attached to an end of the housing 5. The board surface 3 is a play surface with nails in a pachinko machine, for example, and the play mechanism itself is omitted.

Further, a curved mirror 2 is installed inside the housing 5 so as to face the liquid crystal display 1. The curved mirror 2 is a mirror having the shape of an aspherical trick, and at the same time as reflecting, acts as a convex lens, condenses, and generates a virtual image at a distant position (a position deeper than the board surface).
Also, since this virtual image is enlarged by the curved mirror 2,
It is possible to take a larger angle of view than the original display. Therefore, the display made by the liquid crystal display 1 becomes a large distant virtual image.

More specifically, if the viewpoint of the player is 6, the distance from the viewpoint 6 to the board 3 is set to 550 mm, and if a 2.8-inch liquid crystal display 1 is used, the display image becomes An image of 8.3 inches is displayed at a distance of 1000 mm (distance L from display image position to board surface = 450 mm). This is at the position of the board 3.
Equivalent to 5 inches, the player's viewing angle θ = 9.6 ° x
7.2 °.

A flat mirror (or a mirror having a gentle convex surface) 4 is mounted near the liquid crystal display 1 in the housing 5. The display light of the liquid crystal display 1 is reflected by the mirror 4 and is emitted upward out of the board 3. As a result, the contents of the game can be grasped from other customers and clerks looking over the player's head, and the player can be more excited. If the clerk needs to look further in from above, a method of directly looking at the liquid crystal display 1 is also possible.

In the above embodiment, the liquid crystal display 1
May be changed as appropriate. A half mirror may be interposed between the liquid crystal display 1 and the curved mirror 2 depending on the position of the liquid crystal display 1. In such a case, it goes without saying that the half mirror is attached according to the orientation of the liquid crystal display.

Further, it is more effective to make the image clearer by finishing the periphery of the display surface where the display image appears in dark black color.

[0017]

According to the present invention, it is possible to express a pseudo solid between "virtual image and board surface" by using the software technique.
For this reason, the game becomes more "fun" with a more realistic image. At the same time, the display image is enlarged by using this optical system. For this reason, a large display which is easy to see can be obtained even with a small (inexpensive) display having a small screen.

Further, if a mirror is provided in addition to the virtual image optical system so that the display can be seen by a person other than the player (for example, a hall clerk in the case of a pachinko machine), a plurality of mirrors can be provided even though the optical system is a distant virtual image. It becomes possible for a person to check the displayed contents.
