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.

Accordingly, an object of the present invention is to provide a three-dimensional effect by a simple method by moving a display image back and forth.

[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 main body of a game machine provided with a board, and a display device for collecting display light emitted from the display. A display device for a game machine, comprising an optical system having a curved mirror that illuminates, wherein the display device for a game machine includes means for changing a distance between the display and the optical system.

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, but is, for example, 450 to 550 mm in front of the player. It is determined to form a real image at the position. In a game machine such as a normal pachinko machine, for example, 10
It is preferable to use one having a curvature of 0 to 250 mm. Further, the curved mirror is preferably disposed substantially perpendicularly or substantially parallel to the board surface of the game machine, and may be used in combination with a 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 the 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 light 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.

When a half mirror is used, the reflection mirror may be arranged at a position having an angle from the optical axis of the emitted light, 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.

The means for changing the distance between the display and the optical system means that one or both of the display and the optical system are installed on a guide rail (screw) or the like, and are moved along the rail by a motor or the like. , An air cylinder or a hydraulic cylinder, a display or a frame that accommodates an optical system can be moved by a solenoid or the like. Anything is fine. The movement may be performed automatically by a program pre-installed in the computer or manually by a player by manual operation.

The present invention refers to the position from the main body of the game machine to the viewpoint of the player, and is preferably in front of the above-mentioned game machine and 450 to 550 m in front of the player.
Although it is preferable to project a real image at the position of m, using a mirror having an aspherical trick shape as a curved mirror,
At the same time as being reflected, it plays the role of a convex lens, condensing,
A virtual image may be generated in a distant place.

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 housing, and a liquid crystal display 2 is incorporated in a lower portion of the housing. Liquid crystal display 2
Are composed of a liquid crystal panel, a bulb of a backlight, a light guide plate, and the like, which are housed in a case such that a liquid crystal surface 2a of the liquid crystal panel is exposed. Various images according to the game content are displayed on the liquid crystal display 2, and the display light generated by the liquid crystal display 2 is emitted from the liquid crystal surface 2a. A board surface 5 is attached to the end of the housing 1. The board surface 5 is a play surface with nails, for example, in a pachinko machine, and the play mechanism itself is omitted. An opening 6 from which light is emitted is opened.

On the upper part of the housing 1, a concave curved mirror 3 is arranged downward at a position facing the liquid crystal display 2. The concave curved mirror 3 is accommodated in a mirror case 7 that holds the whole, and the mirror case 7 itself has a structure that can move in the vertical direction of the housing 1. More specifically, projections 8 protrude from both side surfaces of the mirror case 7, and incorporate a movable arm 9 having an oblong oblong hole. The movable arm 9 is provided with a sliding member 10 at a front portion thereof and a solenoid 1 at a rear portion thereof.
It is held at 1. When energized, the solenoid 11 pulls the movable arm 9 toward the solenoid 11, and when energized, returns to its original position by a built-in spring force. Therefore, when the solenoid 11 is energized, the movable arm 9 moves to the solenoid 11 side, and the projection 8 is pushed up, so that the mirror case 7 moves upward (the state of the solid line in FIG. 1). On the other hand, when the power is turned off, the movable arm 9 moves to the sliding member 10 side, so that the projection 8 is pushed down, so that the mirror case 7 moves downward (the state shown by the broken line in FIG. 1). ON and OFF of the power supply to the solenoid 11 are controlled according to a program.

Further, inside the housing 7, a half mirror 4 is provided between the liquid crystal display 2 and the curved mirror 3 at 45 °.
It is installed at an angle. Therefore, the liquid crystal display 2
The light L1 emitted from the liquid crystal surface 2a of the half mirror 4
And reaches the curved mirror 3. Light L1 by curved mirror 3
Is reflected and becomes reflected light L2, and the half mirror 4
Leads to. The light L3 that has again reached the half mirror 4 is reflected there and is emitted outward from the display opening 6 of the board 5 (L4). At this time, since the real image is formed outside the opening 6, the player feels that the display entity exists here.

With the above configuration, when the solenoid 11 is energized according to the program during the play of the player,
Since the mirror case 7 moves upward and the distance between the liquid crystal surface 2a and the curved mirror 3 is widened, the magnification of the display is reduced, and the real image forming position is also retracted to the display opening 6 side.
On the other hand, when the energization of the solenoid 11 is stopped, the reverse occurs.

The present invention is not limited to the above configuration. A flat mirror (or a mirror having a gently convex surface) is assembled at a portion facing the liquid crystal display 1, and the display light reflected by the flat mirror is reflected by the half mirror 4. The light may be reflected and emitted upward out of the board surface 5. 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.

Further, the liquid crystal display 2 may be arranged on left and right wall surfaces. In such a case, it goes without saying that the half mirror 4 and the curved mirror 3 are mounted according to their directions. Further, the half mirror 2 does not necessarily need to be set at 45 °, and the angle may be slightly changed in accordance with the arrangement form.

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

Further, the means for changing the distance between the liquid crystal display and the curved mirror is not limited to the one described above, and for example, the one shown in FIG. 2 can be used. FIG. 2 is a schematic diagram when the liquid crystal display is moved. In FIG. 2A, reference numeral 21 denotes a liquid crystal display, and the same one as in FIG. 1 can be used. A nut 25 is attached to the liquid crystal display 21, and the nut 25 moves left and right in the figure along a guide 26 by rotating a screw 24 by a motor 23. A curved mirror 22 is provided at a position facing the liquid crystal display 21. The curved mirror 22 reflects light from the liquid crystal display 21 and also functions as a lens to generate a real image on the liquid crystal display side. Therefore, when the motor 23 is rotated, the rotational force is transmitted to the screw 24, and the liquid crystal display 21 is moved, the real image also moves.

As shown in FIG. 2B, by disposing a half mirror 27 between the liquid crystal display 21 and the curved mirror 22, the degree of freedom of the installation angle of the liquid crystal display 21 and the curved mirror 22 is increased. Alternatively, the size of the device may be reduced.
In FIG. 2B, the display light emitted from the liquid crystal display 21 is reflected by the half mirror 27, then condensed and reflected by the curved mirror 22, and transmitted through the half mirror 27. As a result, the display image becomes a display protruding toward the player. Here, when the liquid crystal display 21 is moved by the motor 23, the real image also moves.

FIG. 2 is a schematic representation, in which the board surface and the like are omitted, but the board surface is on the liquid crystal display side.

[0025]

According to the present invention, the display image can be moved back and forth, so that the realism is increased and the game is more enjoyable by software techniques such as raising the image near the player at the climax of the game. It will be.

At the same time, since the optical system in the amusement machine is a coaxial optical system, 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 at different places. As a result, the projected image can be seen by the player, and a powerful game can be enjoyed.
