BEST MODE FOR CARRYING OUT THE INVENTION The image reproducing film of the present invention can be manufactured by recording a hologram on a recording material. As shown in FIG. 7, a hologram is formed by dividing a laser beam 20 into two directions by a beam splitter 21 on a recording material 26 made of dichromated gelatin, a photopolymer, a silver salt-based emulsion, and the like. Object light 2
2) is spread by a lens 24 and applied to an object 27, and the reflected light is applied to a recording material 26. Then, the other light (reference light 25) is changed in direction by the mirror 23 and spread by the lens 24 to be applied. That is, the recording material is manufactured by superposing and exposing these two lights to light and then developing.

In recording a hologram, a lens for imaging an object is not used, and nothing that looks like an image of the object is shown. Instead 1000-70 in 1mm
00 very fine and complex striped patterns are recorded. This fringe is an interference fringe. The laser light is divided into two parts, and is superimposed again as the object light and the reference light. As a result, the fringes are caused by interference phenomena that strengthen and destruct each other. The interference fringes include information on the brightness of the object, that is, information on the direction in which light came along with the amplitude, that is, the phase, and a hologram is a recording of such information in the form of interference fringes. . In other words, holograms do not record the image of the object itself on the film as in a conventional photograph, but freeze the light itself propagating from the object in the form of interference fringes by introducing reference light. It can be said that it was recorded.

In order to release the frozen light and generate it again, the reproduction illumination light 29 may be applied as shown in FIG. A hologram is a kind of diffraction grating that records fine interference fringes, and when it is irradiated with reproduction illumination light, in addition to the light that travels straight, the light that travels in another direction is generated, and the recorded object Appears on the screen as if the image were there.

According to the hologram of the present invention, the visible light of the player incident on the image reproduction film is almost transmitted and the background image can be seen, but the reproduction illumination light is almost reflected and the image is three-dimensionally formed by the built-in image information. It can be played back and displayed. For example, Lippmann holograms have excellent wavelength selectivity and show sharp reflection peaks at specific wavelengths. Therefore, if the reflection peak of the hologram coincides with the center of this wavelength, the reproduction illumination light is 90%
At the same time as displaying an image after being reflected to some extent, it is possible to transmit the background by about 90% of the entire visible light. That is,
The image information contained in the image reproduction film can be superimposed and displayed on the numbers on the conventional display screen of the game board. The reproduction illumination light normally enters the image reproduction film obliquely, but there is no restriction on the direction in which the visible light is incident on the image reproduction film, and the visible light does not necessarily need to be perpendicularly incident on the film. In addition, the transmittance of visible light may be 0 to
What is necessary is just to adjust suitably between about 90%. That is, the transmittance is increased when a picture or the like is to be superimposed on a conventional display screen. However, when a picture or the like is shifted slightly up, down, left, or right from the conventional display screen, the transmittance does not necessarily exist because the background does not exist. You do not need to be high.

The image projection film of the present invention functions as a transparent film by transmitting light vertically incident on the film surface within a certain range, but functions as a transparent film when incident light obliquely from outside the range. It functions as an opaque film such as frosted glass to display a projected image, and specifically has the following structure. As shown in FIGS. 9 to 10, the image projection film 32 is formed by superimposing multiple layers of two kinds of transparent substances A and B having different thicknesses and non-uniform thicknesses at the optical micro level and having different refractive indices. Thus, the overall thickness can be considered macroscopically uniform. Light coming from the front of the player, that is, light incident from a direction substantially perpendicular to the image projection film, penetrates through the layer interface while being refracted at the layer interface, so that the image on the conventional display screen is directly transmitted to the player. Is transmitted. However, light incident on the film from an oblique direction proceeds while repeating irregular reflection at each layer interface. Since the layers are non-parallel and non-uniform in thickness, light exits in a rather random direction when exiting the opposite surface.
As a result, even if the incident light is a parallel light, the transmitted light is scattered widely in a random manner, so that it works as an opaque screen and can project a projected image.

A preferred embodiment of the present invention will be described with reference to the drawings. Near the center of the pachinko machine game board, for example, FIG.
An accessory 1 as shown in FIG. The accessory 1 has an opening / closing blade 2 attached to both upper sides thereof, and accepts a ball only while the opening / closing blade 2 is open. The accepted ball 3 falls into the guiding space 4 and is guided to the winning opening. However, the course of the ball is fluctuated by the ball guiding piece 5 to give a chance to the winning at the jackpot winning opening, and to the jackpot winning opening. The number of continuous opening and closing of the opening and closing blade 2 is changed by winning. A big hit state in which the opening / closing wings 2 are continuously opened, or when the state immediately before that is reached, the winning state is displayed on the display screen 6 to notify the player and increase the entertainment effect. It is.

In the first embodiment shown in FIGS. 1 and 2, an image reproducing film 7 is attached below a guidance space 4 in front of a display screen 6 such as a liquid crystal, and a light source 8 is provided above the guidance space 4. Is attached. When the reproduction illumination light 18 emitted from the light source 8 and reflected by the glass 12 hits the image reproduction film 7, a picture pattern appears and is displayed. If light is emitted from the light source when the jackpot is reached, for example, below the display screen 6 displaying “777”,
As shown in this figure, it can be displayed in parallel with "big hit !!". These pictures were recorded by holographic stereograms, which are holographically synthesized on a recording material, using two-dimensional images viewed from a plurality of different viewpoints as original images. Is what you do. In addition, these patterns can be recorded on a recording material by illuminating a solid model with an object light and further superimposing a reference light, and can also be recorded by a grating image used to enhance credit card security. . The present image reproduction film does not need to transmit the visible light of the player. In addition, the position of the light source does not necessarily need to be mounted in front of the display screen 6, and can be mounted at any position in the game board where the picture can be reproduced.

In the second embodiment shown in FIGS. 3 and 4, an image reproducing film 7 is attached to a glass 12 in front of a display screen 6, and a light source 8 is attached above the guiding space 4. Reproduction illumination light 18 emitted from the light source 8
Hits the image reproduction film 7, and a picture pattern appears. If the light source is turned on and the reproduction illumination light is emitted when the state immediately before the jackpot is reached, “reach !!” can be superimposed and displayed on the liquid crystal display screen as shown in FIG. The image reproduction film used in the present embodiment desirably transmits about 90% of a player's visible light. The same effect can be obtained by attaching the image reproduction film 7 to the decorative frame 13 as shown in FIG.

In a third embodiment shown in FIGS. 5 and 6, a single image is formed in front of the display screen 6, behind the guidance space 4, with the image reproduction film 7 up and the image projection film 32 down. Was placed. Above the guidance space 4, a light source 8 for emitting reproduction illumination light 18 from the front of the image reproduction film 7 is arranged slightly downward. A light source 17 that emits projection light backward to the board surface is disposed below the accessory 1, and an optical member 16 having an image projected on an image projection film 32, a lens 15 for enlarging the image, and reflecting 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 at the same time to reproduce a pattern (“HIT !!” in this figure) on the upper part of the display screen 6 by the reproduction illumination light 18 and to project the projection light 19. Thus, a pattern (a pattern in which several star shapes are combined in this drawing) is projected and projected on the image projection film 32. Here, as a method of holding the image information in the optical member, 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, 17 can be arranged at any positions in the game board.
