[0005]
DETAILED DESCRIPTION OF THE INVENTION
The image reproducing film of the present invention can be produced by recording a hologram on a recording material. As shown in FIG. 7, a hologram is a recording material 26 made of dichromated gelatin, a photopolymer, a silver salt emulsion or the like, and a laser beam 20 is divided into two directions by a beam splitter 21 and one light ( The object light 22) is spread by the lens 24 and applied to the object 27, and the reflected light is applied to the recording material 26. Then, the other light (reference light 25) is changed in direction by the mirror 23 and spread by the lens 24 and applied. That is, the recording material is manufactured by superposing and exposing these two lights and then developing the recording material.
[0006]
In hologram recording, a lens for imaging an object is not used, and nothing that looks like an image of the object is captured. Instead, 1000 to 7000 very fine and complicated striped patterns are recorded in 1 mm. This fringe is an interference fringe, which is caused by an interference phenomenon that strengthens and weakens each other as a result of dividing the laser light into two and then superimposing it again as object light and reference light. This interference fringe includes information on the brightness of the object, that is, information on the direction from which the light has come, that is, the phase, and the hologram is a record of this information in the form of interference fringes. . In other words, the hologram is not an image of the object itself recorded on the film like a conventional photograph, but the light propagating from the object is frozen in the form of interference fringes by introducing the reference light. It can be said that it was recorded.
[0007]
In order to release the frozen light and generate it again, as shown in FIG. A hologram is a kind of diffraction grating in which fine interference fringes are recorded. When the reproduction illumination light is applied to this hologram, in addition to the light that travels straight, light that diffracts and travels in another direction is generated. The reconstructed image 31 appears as if there is.
[0008]
The hologram of the present invention transmits almost the player's visible light incident on the image reproduction film and allows the background image to be seen through. However, the reproduction illumination light is almost reflected, and the image is reproduced three-dimensionally by the built-in image information. Can be displayed. For example, Lippmann holograms have excellent wavelength selectivity and show a sharp reflection peak at a specific wavelength. Accordingly, if the reflection peak of the hologram is made coincident with the center of the wavelength, the reproduction illumination light is reflected by about 90% and an image is displayed. At the same time, the background can be transmitted by about 90% of the entire visible light. That is, it is possible to display the image information built in the image reproduction film on the number on the conventional display screen of the game board.
Although the reproduction illumination light is normally incident on the image reproduction film at an angle, visible light is not limited in the direction in which the reproduction illumination light is incident on the image reproduction film, and the visible light does not necessarily have to be incident on the film perpendicularly.
In addition, the visible light transmittance may be appropriately adjusted between about 0% and 90% as necessary. In other words, the transmittance is increased when it is desired to display a pattern or the like superimposed on the conventional display screen, but when the pattern or the like is displayed slightly shifted up, down, left or right from the conventional display screen, the transmittance does not necessarily exist because the background does not exist. There is no need to make it high.
[0009]
The image projection film of the present invention functions as a transparent film that transmits light that is perpendicularly incident on the film surface within a certain range, but light that is incident obliquely from outside the range is diffusely reflected and transmitted. It functions as an opaque film such as frosted glass, and displays a projected image. Specifically, it has the following structure.
As shown in FIGS. 9 to 10, the image projection film 32 is obtained by superposing multiple layers of A and B transparent materials having different thicknesses and different refractive indexes on the optical micro level in multiple layers. Thus, the overall thickness can be regarded as being macroscopically uniform.
Light coming from the front direction of the player, that is, light incident from a direction substantially perpendicular to the image projection film is refracted at the layer interface and penetrates through, so the image on the conventional display screen remains as it is to the player. Communicated. However, light incident on the film from an oblique direction travels while repeating irregular reflection at each layer interface. Since the layers are non-parallel and non-uniform in thickness, light exits in a fairly random direction when it exits the opposite surface. As a result, even if the incident light is a parallel light beam, the transmitted light is randomly and widely scattered, so that it can act as an opaque screen and project a projected image.
[0010]
A preferred embodiment of the present invention will be described with reference to the drawings.
For example, an accessory 1 as shown in FIG. 11 is disposed in the center of the game board of the pachinko machine. This accessory 1 is provided with opening / closing blades 2 on both upper sides thereof, and accepts balls only while the opening / closing blades 2 are open. The accepted ball 3 falls into the guide space 4 and is guided to the winning opening, but the ball guiding piece 5 changes the course of the ball to give a chance to win the winning jackpot, The number of continuous opening / closing of the opening / closing blade 2 is changed by winning. And, when it becomes a big hit state where the opening and closing blade 2 is continuously opened, or when it is just before it, those winning states are displayed on the display screen 6 to inform the player and increase the amusement effect It is.
[0011]
In the first embodiment shown in FIGS. 1 and 2, an image reproduction film 7 is attached to the front of the display screen 6 such as a liquid crystal and below the guide space 4, and a light source 8 is attached to the top of the guide space 4. ing. When the reproduction illumination light 18 emitted from the light source 8 and reflected by the glass 12 strikes the image reproduction film 7, a picture appears and is displayed. If light is emitted from the light source when the big hit state is reached, for example, under the display screen 6 where “777” is displayed, “big hit!” Can be displayed in parallel as shown in the figure. These pictures were recorded by using a holographic stereogram that was synthesized in a holographic manner on a recording material, using a planar image viewed from a plurality of different viewpoints as the original image. To do. In addition, these patterns can be recorded on the recording material by applying object light to the three-dimensional model and further overlaying the reference light, and can also be recorded by a grating image used to enhance the security of the credit card. . The image reproducing film does not need to transmit the player's visible light.
Further, the position of the light source does not necessarily have to be attached in front of the display screen 6, and can be attached at an arbitrary position in the game board where the picture can be reproduced.
[0012]
In the second embodiment shown in FIGS. 3 to 4, the image reproduction film 7 is attached to the glass 12 in front of the display screen 6, and the light source 8 is attached to the upper part of the guide space 4. When the reproduction illumination light 18 emitted from the light source 8 strikes the image reproduction film 7, a picture appears. If the light source is turned on and the reproduction illumination light is emitted when the state is just before the big hit, it is possible to display “REACH!” On the liquid crystal display screen as shown in FIG. The image reproducing film used in the present embodiment is preferably one that transmits about 90% of the player's visible light.
Note that the same effect can be obtained when the image reproducing film 7 is attached to the decorative frame 13 as shown in FIG.
[0013]
In the third embodiment shown in FIGS. 5 to 6, an image reproduction film 7 and an image projection film 32 are arranged in a single sheet in front of the display screen 6 and behind the guidance space 4. . A light source 8 for emitting reproduction illumination light 18 from the front of the image reproduction film 7 is disposed slightly above the guide space 4.
A light source 17 that emits projection light backward is disposed on the bottom of the accessory 1, and an optical member 16 having an image projected on the image projection film 32, a lens 15 that magnifies the image, and reflects light. The mirror 14 is disposed on the light path between the light source 17 and the image projection film 32.
When the big hit state is reached, the light source 8 and the light source 17 are turned on simultaneously, and the reproduction illumination light 18 reproduces the pattern (“HIT!” In this figure) on the display screen 6 and the projection light 19. As a result, a pattern (in this figure, a combination of several star shapes) is projected and projected on the image projection film 32.
Here, as a method for causing the optical member to hold the image information, the image information may be built in the transparent object, or a sticker on which the image information is printed may be attached.
Further, the optical member 16, the lens 15, and the light sources 8 and 17 can be arranged at arbitrary positions in the game board.
[0014]
