Description

Technical Field

[0001] The present invention relates to a display device and a gaming machine.

Background Art

[0002] In recent years, a display device has been proposed in which a plurality of light sources are arranged for a single light guide plate such that the directions of the light emitted from the side surfaces are different, and a plurality of dot patterns capable of displaying different display patterns corresponding to the respective emitted lights are mixed on the flat surface portion of the light guide plate. According to such a display device, since a plurality of display patterns can be represented by a single light guide plate, for example, when used in a pachinko gaming machine, it is possible to represent a display pattern according to the effect.

[0003] In particular, as shown in FIGS. 28 and 29 of Patent Document 1, it is possible to represent it like an animation by sequentially lighting the light sources corresponding to a plurality of display patterns and sequentially displaying the plurality of display patterns (Patent Document 1).

[0004] Further, a display panel made of a transparent material and an element group including dot-like reflection elements provided on the surface or inside of the display panel as constituent elements and displaying a specific display pattern as a whole are provided. The element group is provided for each of a plurality of preset viewpoints, and for each viewpoint, the provided element group reflects light from a light source without separately arranging an optical element for giving a parallax toward the viewpoint on the display panel, and the display pattern displayed by the element group by the reflected light is visually recognized at the set viewpoint and not visually recognized at a non-set viewpoint (Patent Document 2). In this Patent Document 2, the light source is arranged on the front side or the rear side of the display panel, and it is possible to display a display pattern by the light incident not only from the side surface but also from the front side or the rear side.

[0005] However, since both Patent Document 1 and Patent Document 2 use the recesses provided in the light guide plate to guide light and emit light through reflection or the like, there is a problem that only a preset display pattern can be displayed.

[0006] In addition, the display using the conventional light guide plate is limited to two-dimensionally displaying a display pattern on the light guide plate, and a three-dimensional image cannot be displayed.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Therefore, the present invention has been made in view of the above problems, and by projecting an image from a projector onto a transparent resin plate through which the background can be seen, reflecting the image of the projector on the transparent resin plate, and displaying images with a parallax on the left and right eyes of an observer, a display device that can display a three-dimensional image while allowing the background side to be visible is provided.

Means for Solving the Problems

[0009] The present invention has adopted the following means to achieve the above main object.

[0010] The display device according to the present invention includes a right-eye projector that emits an image for the right eye, a left-eye projector that emits an image for the left eye, and a transparent resin plate that reflects a part of the images emitted from the right-eye projector and the left-eye projector. On the front or back surface of the transparent resin plate, there are a plurality of right-eye reflecting grooves formed by reflecting grooves having a groove angle for reflecting an image from the right-eye projector to a preset viewing position of the observer's right eye, and a plurality of left-eye reflecting grooves formed by reflecting grooves having a groove angle for reflecting an image from the left-eye projector to a preset viewing position of the observer's left eye. It is characterized by including a plurality of them.

[0011] The display device according to the present invention is configured to provide a plurality of reflecting grooves on the front or back surface of a transparent resin plate for reflecting a part of an image from a projector, so that each reflecting groove corresponds to a so-called pixel of a monitor, thereby enabling the display of the projector's image. Furthermore, by providing right-eye reflecting grooves and left-eye reflecting grooves corresponding to a right-eye projector that emits a right-eye image and a left-eye projector that emits a left-eye image, respectively, the observer can visually recognize a stereoscopic image in which the left and right images appear to float on an imaginary intersection plane. Also, since the image from the projector is reflected, a free image can be displayed, unlike a light guide plate. Additionally, since the display device according to the present invention displays an image on the transparent resin plate, the back side can be visually recognized, and the background, pattern, ornament, etc. on the back side can be visually recognized as if they are floating.

[0012] Also, in the display device according to the present invention, it may be characterized in that the right-eye reflecting groove does not reflect an image from the left-eye projector to the viewing position of the right eye, and the left-eye reflecting groove does not reflect an image from the right-eye projector to the viewing position of the left eye.

[0013] By adopting such a configuration, it is possible to prevent the right eye from visually recognizing the left-eye image or the left eye from visually recognizing the right-eye image.

[0014] Furthermore, in the display device according to the present invention, when the horizontal direction is regarded as rows and the height direction is regarded as columns, in the row direction, the right-eye reflection grooves and the left-eye reflection grooves are arranged alternately, and in the column direction, all columns are arranged to be either right-eye reflection grooves or left-eye reflection grooves. This may be a characteristic feature.

[0015] By adopting such a configuration, it is possible to provide an image with a parallax that can be recognized as a stereoscopic image.

[0016] Furthermore, in the display device according to the present invention, when the horizontal direction is regarded as rows and the height direction is regarded as columns, in both the row direction and the column direction, the right-eye reflection grooves and the left-eye reflection grooves are arranged alternately. This may be a characteristic feature.

[0017] By arranging the right-eye reflection grooves and the left-eye reflection grooves in a so-called matrix pattern, that is, by uniformly arranging one reflection groove corresponding to a light element of one pixel, the overall brightness and resolution can be displayed evenly, and a display that is easy to view can be achieved.

[0018] In addition, the display device according to the present invention includes a projector that vertically divides a right-eye exclusive image and a left-eye exclusive image taken in consideration of parallax, and emits an image in which the divided images are arranged alternately in the horizontal direction, a transparent resin plate that reflects a part of the image emitted from the projector, on the front or back surface of the transparent resin plate, at the part where the right-eye exclusive image is projected, there are a plurality of right-eye reflection grooves having a groove angle that reflects to a preset viewpoint position of the observer's right eye, and at the part where the left-eye exclusive image is projected, there are a plurality of left-eye reflection grooves having a groove angle that reflects to a preset viewpoint position of the observer's left eye, and is characterized by including a plurality of them.

[0019] According to such a configuration, by emitting the right-eye image and the left-eye image respectively with one projector and providing the corresponding right-eye reflection groove and left-eye reflection groove, the observer can visually recognize a stereoscopic image in which the left and right images appear to float on the virtual image plane where the images cross.

[0020] In addition, the display device according to the present invention is a display device capable of observing a stereoscopic image at a plurality of observation positions at a predetermined interval in the horizontal direction, at n observation positions α in order from the right 1 , α 2 , α 3 , ···, α n (n is a natural number), considering the parallax, images A taken from n + 1 positions in order from the right with intervals in the horizontal direction 1 , A 2 , A 3 , ···, A n+1 (n is a natural number), a projector that emits a transparent resin plate having a block in which n + 1 reflection regions are set, and this block is formed in a matrix shape as one block, and is provided with the n + 1 reflection regions of the block are assigned the respective images A 1 , A 2 , A 3 , ···, A n+1 emitted from the projector, in each reflection region, the right-eye viewpoints β corresponding to the respective observation positions α 1 , α 2 , α 3 , ···, α n are set as β 1 , β 2 , β 3 , ···, β n and the left-eye viewpoints are set as β 2 , β 3 , β 4 , ···, β n+1 When this is the case, in the viewpoint β n , reflection grooves are respectively formed so that the image A n is reflected.

[0021] By using such a display device, even when the observation position is shifted horizontally, a three-dimensional image that sequentially changes as seen from each observation position can be visually recognized.

[0022] Furthermore, in the display device according to the present invention, in the column direction, it may be characterized in that a transparent resin plate formed entirely of right-eye reflection grooves or left-eye reflection grooves, and in the row direction, the right-eye reflection grooves and the left-eye reflection grooves are alternately provided, and is formed to be capable of reciprocating vertically at high speed.

[0023] By adopting such a configuration, since one reflection groove moves up and down within a certain range, an image can be reflected within that up and down range. As a result, by utilizing the afterimage phenomenon of the human eye, the reflection area by one reflection groove can be widened, and high-resolution display can be performed.

[0024] Furthermore, in the display device according to the present invention, it may be characterized in that a display device or a decoration for displaying an image with an interval is provided on the back side of the transparent resin plate.

[0025] Since the display device of the present invention uses a transparent plate as a display medium, it is also possible to simultaneously visually recognize the image on the back surface, patterns, and decorations together with the image displayed on the transparent resin plate. Therefore, it is also possible to perform an expression by combining both with the image and patterns on the back side. For example, an image of the sea is displayed as a background, and an image of fish swimming is projected onto the transparent resin plate from a projector.

[0026] Furthermore, the display device according to the present invention may be attached to a gaming machine and used.

[0027] By incorporating it into a gaming machine, it becomes possible to perform an effect such that a character pops out from a liquid crystal display arranged on the back side and floats in the air in front, or to perform an effect such that when a device appears, the device is covered with an effect.

Embodiments for Carrying Out the Invention

[0029] (First Embodiment) Hereinafter, the display device 100 according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram of the display device 100 according to the first embodiment, FIGS. 2 and 3 are schematic diagrams of the transparent resin plate 20 viewed from the front, and FIG. 4 is a cross-sectional view taken along line A-A of the transparent resin plate 20 in FIG. 2A. In the present specification and claims, the "image" includes still images, moving images, and also includes the video projected from a projector.

[0030] As shown in FIG. 1, the display device 100 according to the present invention mainly includes a right-eye projector 11, a left-eye projector 12, and a transparent resin plate 20 that reflects the images from these projectors 10.

[0031] The projector 10 is not particularly limited with respect to the type of light source such as a mercury lamp projector, a laser projector, or an LED projector. Also, the projection method is not particularly limited, such as a liquid crystal method, a DLP method, or an LCOS method. The right-eye projector 11 is disposed on the left side with respect to the front (observer side) of the transparent resin plate 20, and the left-eye projector 12 is disposed on the right side with respect to the front of the transparent resin plate 20. The height at which the projector 10 is installed is not limited, but it is preferably arranged at the same height as the center in the height direction of the transparent resin plate 20. The right-eye projector 11 emits a right-eye image taken in consideration of parallax, and the left-eye projector 12 emits a left-eye image taken in consideration of parallax. Note that even for an image emitted from the same projector, distortion occurs when projected onto the transparent resin plate 20 depending on the distance. Therefore, it is preferable to emit a corrected image subjected to correction processing such as trapezoidal correction according to the installation position of the projector 10.

[0032] As shown in FIG. 1, the transparent resin plate 20 has a function of reflecting the image emitted from the projector 10 and condensing the light at the viewing position of the observer. As the transparent resin plate 20, a resin plate having a high light transmittance with a light transmittance of 80% or more is used. For example, an acrylic resin plate, a polycarbonate resin plate, a PET resin plate, etc. can be preferably used. Of course, it is not limited to these resins. As shown in FIG. 2, on the transparent resin plate 20, a plurality of right-eye reflection grooves 21 with a groove angle set so that light is reflected to a preset viewing point of the observer's right eye based on the incident angle of the light emitted from the right-eye projector 11 are provided. Also, based on the incident angle of the light emitted from the left-eye projector 12, a plurality of left-eye reflection grooves 22 with a groove angle set so that light is reflected to a preset viewing point of the observer's left eye are provided (in the figure, the ones represented by diagonal lines are the right-eye reflection grooves 21, and the ones without diagonal lines are the left-eye reflection grooves 22). It is preferable that the right-eye reflection grooves 21 and the left-eye reflection grooves 22 are provided so that the densities of the right-eye reflection grooves 21 and the left-eye reflection grooves 22 are the same. By providing them in a matrix form as a whole so that they have the same density, the resolution and brightness of the images displayed on the right eye and the left eye can be made the same, and an easy-to-see image can be obtained. As an example of the arrangement of the right-eye reflection grooves 21 and the left-eye reflection grooves 22, for example, as shown in FIG. 2A, when the horizontal direction is the row and the height direction is the column, in the row direction, the right-eye reflection grooves 21 and the left-eye reflection grooves 22 are arranged alternately, and in the column direction, they may be arranged so that all are the right-eye reflection grooves 21 or the left-eye reflection grooves 22. At this time, the right-eye reflection grooves 21 and the left-eye reflection grooves 22 constituting the column do not have to be in one column, and as shown in FIG. 2B, they may be alternately formed with a plurality of columns as one unit. Also, as shown in FIG. 3A, in both the row direction and the column direction, the right-eye reflection grooves 21 and the left-eye reflection grooves 22 may be arranged alternately. At this time, as shown in FIG. 3B, a plurality of right-eye reflection grooves 21 and left-eye reflection grooves 22 may be arranged so that each is one unit.

[0033] Next, the forms of the right-eye reflecting groove 21 and the left-eye reflecting groove 22 will be described with reference to FIG. 4. FIG. 4 shows the A-A cross-sections (hatching is omitted) of the grooves 22a, 21a, 22b, and 21b in FIG. 2. In FIG. 4, although a broken line is used for the transparent resin plate, when indicating the traveling line of light, for convenience, it is not shown accordingly. Considering that the incident angle γ1 and the exit angle γ2 of the emitted light L1 emitted from the right-eye projector 11 are equal, the groove angle θR1 is formed so that the light is reflected to the viewing point of the observer's right eye for the right-eye reflecting groove 21a. Similarly, for the right-eye reflecting groove 21b, considering that the incident angle and the exit angle of the emitted light L2 emitted from the right-eye projector 11 are equal, the groove angle θR2 is formed so that the light is reflected to the viewing point of the observer's right eye. For the left-eye reflecting grooves 22a and 22b as well, considering that the incident angle and the exit angle of the image from the left-eye projector 12 are equal in the same way of thinking, the groove angles θL1 and θL2 are formed so that the light is reflected to the viewing point of the observer's left eye. At this time, the right-eye reflecting groove 21 and the left-eye reflecting groove 22 prevent the image emitted from the left-eye projector 12 from reaching the observer's right eye and prevent the image emitted from the right-eye projector 11 from reaching the observer's left eye. For example, taking the right-eye reflecting groove 21a shown in FIG. 4 as an example, the emitted light L3 emitted from the left-eye projector 12 is reflected in a direction not related to the observer and does not reach the observer. Each of the right-eye reflecting grooves 21 and the left-eye reflecting grooves 22 formed on the transparent resin plate 20 corresponds to a so-called pixel, and the brightness and resolution of the reflected image are determined by the size and density of the right-eye reflecting grooves 21 and the left-eye reflecting grooves 22. Note that the surfaces of the right-eye reflecting groove 21 and the left-eye reflecting groove 22 are preferably formed as smooth surfaces. This is because if they are formed as rough surfaces, it becomes difficult to reflect the image from the projector 10 in a certain direction, and also because the transparency is reduced, there is a possibility that the back side of the transparent resin plate 20 cannot be visually recognized. The smaller the size of the right-eye reflecting groove 21 and the left-eye reflecting groove 22, the smaller each pixel becomes, and the narrower the pitch, the higher the density. Therefore, it is preferably arranged in a matrix form as small and dense as possible as a whole.Specifically, the maximum width of the right-eye reflection groove 21 and the left-eye reflection groove 22 is preferably 100 μm or less. The pitch of each reflection groove is preferably at least 300 μm or less.

[0034] The display device 100 thus manufactured can be visually recognized as a three-dimensional image that appears to float with the virtual image plane 90 where the left and right images intersect as a reference plane from the observer. Since the display device 100 according to the present invention is projected onto the transparent resin plate 20, the back side can be visually recognized through the projected display. Therefore, by arranging a display device such as a liquid crystal that displays an image with a gap on the back or a decoration such as a character, the image projected onto the transparent resin plate 20 with respect to the image or decoration on the back can be made to appear as if it is floating in the air.

[0035] (Second Embodiment) Hereinafter, the display device 100 according to the present invention will be described in detail with reference to the drawings. FIG. 5 is a conceptual diagram of the display device 100 according to the second embodiment.

[0036] As shown in FIG. 5, the display device 100 according to the present invention mainly includes a projector 10 and a transparent resin plate 20. The relationship between the projector 10 and the transparent resin plate 20 is such that an observer is in front of the transparent resin plate 20, and the projector 10 is arranged above the front direction of the transparent resin plate 20 in the vertical direction and at the center of the transparent resin plate 20 in the horizontal direction as shown in FIG. 5A.

[0037] Similar to the first embodiment, the projector 10 is not particularly limited in terms of the type of light source and the projection method. The image emitted from the projector 10 is processed into an image in which a plurality of images are vertically divided and the right-eye exclusive image 14 and the left-eye exclusive image 15 are arranged alternately as shown in FIG. 6. It should be noted that the emitted image preferably projects a corrected image that has been subjected to correction processing such as trapezoidal correction according to the installation position of the projector 10.

[0038] As shown in Fig. 7, the transparent resin plate 20 is provided with a right-eye reflection groove 21 and a left-eye reflection groove 22 in accordance with the regions where the right-eye exclusive image 14 and the left-eye exclusive image 15 emitted from the projector 10 are emitted. That is, in the column direction, all of one column is formed by either the right-eye reflection groove 21 or the left-eye reflection groove 22, and in the row direction, the right-eye reflection groove 21 and the left-eye reflection groove 22 are provided alternately.

[0039] As shown in the cross-sectional view taken along line B-B of Fig. 7 shown in Fig. 8, for the form of the left-eye reflection groove 22, the left-eye reflection groove 22c on the left side from the center of the transparent resin plate 20 and the left-eye reflection groove 22d on the right side from the center of the transparent resin plate 20 are formed with groove angles θcLx and θdLx such that light is reflected to the viewing point of the observer's left eye, considering that the incident angle and the exit angle of the light of the left-eye exclusive image 15 emitted from the projector 10 are equal. On the other hand, for the right-eye reflection groove 21c on the left side from the center of the transparent resin plate 20 and the right-eye reflection groove 21d on the right side from the center of the transparent resin plate 20, groove angles θcRx and θdRx are formed such that light is reflected to the viewing point of the observer's right eye, considering that the incident angle and the exit angle of the light of the right-eye exclusive image 14 emitted from the projector 10 are equal.

[0040] On the one hand, for the right-eye reflection groove 21 and the left-eye reflection groove 22 in the C-C cross-section of FIG. 7 shown in FIG. 8, the groove angles are formed by adjusting the height so that light is reflected to the observer's viewing point. Since the concept is the same for both the right-eye reflection groove 21 and the left-eye reflection groove 22, taking the left-eye reflection groove 22e, the left-eye reflection groove 22f, the left-eye reflection groove 22g, and the left-eye reflection groove 22c as examples, as shown in the C-C cross-section, considering that the incident angle and the exit angle of the light of the left-eye exclusive image 15 emitted from the projector 10 are equal, the groove angles θeLy, θfLy, θgLy, and θcLy are formed so that light is reflected to the viewing point of the observer's left eye. Thus, as shown in FIG. 9, for the right-eye reflection groove 21 and the left-eye reflection groove 22 according to the second embodiment, when the left-right direction of the transparent resin plate 20 is the X-axis direction, the height direction is the Y-axis direction, and the front-rear direction is the Z-axis direction, reflection angles are provided with respect to both the X-axis and the Y-axis. At this time, when ensuring the groove angle by Y-axis rotation + X-axis rotation, it can be manufactured by setting the X-axis rotation as θaX and the Y-axis rotation as θaY. On the other hand, when ensuring the groove angle in the same way by Y-axis rotation + Z-axis rotation, it can be manufactured by setting the Y-axis rotation as θaY and the Z-axis rotation as θaZ.

[0041] The display device 100 thus manufactured emits a stereoscopic image obtained by dividing the right-eye exclusive image 14 and the left-eye exclusive image 15 by one projector 10, and by displaying the right-eye exclusive image 14 and the left-eye exclusive image 15 on the respective right eye and left eye, it can be visually recognized as a stereoscopic image.

[0042] (Third Embodiment) The transparent resin plate 20 of the display device 100 according to the third embodiment is shown in FIG. 10. The display device 100 according to the third embodiment is a display device capable of appreciating a stereoscopic image according to the moved position even when the observer's observation position moves in the horizontal direction, as shown in FIGS. 11A to 13. Hereinafter, in the third embodiment, α 1 ~α 5 When there are five observation positions as shown, it will be described as an example.

[0043] As shown in Fig. 11A, the display device 100 according to the third embodiment mainly includes a projector 10 and a transparent resin plate 20. The relationship between the projector 10 and the transparent resin plate 20 is such that in the left-right direction, it is positioned at the center of the transparent resin plate 20, and in the up-down direction, it is arranged above the front direction of the transparent resin plate 20.

[0044] As shown in Fig. 14B, the image projected from the projector 10 is an image obtained by combining images taken from six directions, considering the observer's parallax, with the camera C 1 installed on the far right side of the subject and successively, C 2 、C 3 、C 4 、C 5 、C 6 installed at an interval of about 60 mm to 70 mm in the horizontal direction according to the distance between the adult's two eyes towards the subject 95. The distance D from the camera to the zero plane of the subject is set considering the distance between the observer and the transparent resin plate. The image taken by the camera C 1 becomes the image represented by the imaging plane S 1 and, as shown in Fig. 14A, is the image A 1 with the center line M 1 shifted to the left. The image taken by the camera C 3 becomes the image represented by the imaging plane S 3 slightly shifted from the right side of the front, and, as shown in Fig. 14A, is the image A 3 with the center line M 3 slightly shifted from the center. The image taken by the camera C 6 becomes the image represented by the imaging plane S 6 and, as shown in Fig. 14A, is the image A 6 with the center line M 6 shifted to the right. The images taken in this way are, for example, the images A 1 、C 3 、C 6 taken by the cameras respectively, as shown in Fig. 14A representing the images A 1 、A 3 、A 6 and are the images taken at the angles of the respective cameras. For example, the image A taken by the camera C 6 arranged on the left side of the subject6 It can capture the left side of the subject, but cannot capture the right side. On the other hand, for the camera C arranged on the right side of the subject 1 The captured image A 1 It can capture the right side of the subject, but cannot capture the right side. When such an image is projected onto the transparent resin plate 20, a similar effect can be obtained. Specifically, as shown in FIG. 10, for the transparent resin plate 20 having a block divided into six reflection regions (the reflection regions having reflection grooves 23a to 23f), the camera C 1 ~C 6 The captured image A 1 ~A 6 Is projected onto the corresponding region. In the embodiment shown in FIG. 10, in the reflection region having the reflection groove 23a, the image A 1 Of camera C 1 , in the reflection region having the reflection groove 23b, the image A 2 Of camera C 2 , in the reflection region having the reflection groove 23c, the image A 3 Of camera C 3 , in the reflection region having the reflection groove 23d, the image A 4 Of camera C 4 , in the reflection region having the reflection groove 23e, the image A 5 Of camera C 5 , in the reflection region having the reflection groove 23f, the image A 6 Of camera C 6 Are combined to be projected. Note that the correspondence between this reflection region and the image of the camera is merely an example and is not limited thereto. In short, for each reflection groove, it is only necessary to set so that any one of the images A 1 ~A 6 Corresponds.

[0045] As shown in FIG. 10, the transparent resin plate 20 has a combination of six reflection regions (a to f) as one block, and these blocks are arranged in a matrix. In the six reflection regions (a to f), reflection grooves 23 for reflecting the image emitted from the projector 10 in a predetermined direction are respectively formed. In this embodiment, each reflection groove 23 is formed as follows. (1) α1 For an observer at the observation position, as shown in FIG. 11A, the camera C 1 captures an image A 1 is formed with a reflection groove 23a formed at a groove angle that reflects the image to the right-eye viewpoint, and the camera C 2 captures an image A 2 is formed with a reflection groove 23b formed at a groove angle that reflects the image to the left-eye viewpoint. (2) α 2 For an observer at the observation position of α, as shown in FIG. 11B, since the right-eye viewpoint moves to the position of the left-eye viewpoint at the observation position of α 1 the observer can visually recognize the image A 2 captured by the camera C 2 with the right eye. For the left eye, a reflection groove 23c is formed at a groove angle that reflects the image A 3 captured by the camera C 3 to the left-eye viewpoint. Similarly, in the following, (3) α 3 For an observer at the observation position of α, as shown in FIG. 12A, since the right-eye viewpoint moves to the position of the left-eye viewpoint at the observation position of α 2 the observer can visually recognize the image A 3 captured by the camera C 3 with the right eye. For the left eye, a reflection groove 23d is formed at a groove angle that reflects the image A 4 captured by the camera C 4 to the left-eye viewpoint. (4) α 4 For an observer at the observation position of α, as shown in FIG. 12B, since the right-eye viewpoint moves to the position of the left-eye viewpoint at the observation position of α 3 the observer can visually recognize the image A 4 captured by the camera C 4 with the right eye. For the left eye, a reflection groove 23e is formed at a groove angle that reflects the image A 5 captured by the camera C 5 to the left-eye viewpoint. (5) α 5 For an observer at the observation position of α, as shown in FIG. 13, since the right-eye viewpoint moves to the position of the left-eye viewpoint at the observation position of α 4 the observer can visually recognize the image A 5 captured by the camera C 5can be visually recognized with the right eye. For the left eye, the camera C 6 captures the image A 6 A reflecting groove 23f is formed at a groove angle that reflects the image A captured by 6 to the left-eye viewpoint.

[0046] For an observer at the observation position of α 1 the display device 100 thus manufactured visually recognizes the image A with the right eye 1 and visually recognizes the image A with the left eye 2 Since the image A 1 and the image A 2 have a parallax, they can be visually recognized as a stereoscopic image. From this state, when the observer moves to the observation position of α 2 the observer visually recognizes the image A 2 with the right eye and visually recognizes the image A 3 with the left eye. Since the image A 2 and the image A 3 have a parallax, they can be visually recognized as a stereoscopic image. That is, the image A 2 visually recognized with the left eye before the movement can be recognized as a right-eye image after the movement, and the left eye newly visually recognizes the image A 3 . Similarly, when moving from the observation position of α 2 to the observation position of α 3 , or from the observation position of α 3 to the observation position of α 4 , the image visually recognized with the left eye before the movement can sequentially be recognized as a right-eye image after the movement, and the left eye newly visually recognizes a different image. In this way, different stereoscopic images can be sequentially visually recognized depending on the observation position.

[0047] In the above-described third embodiment, the case where the observer visually recognizes a stereoscopic image at five positions has been described as an example, but the number of observation positions to be observed is not limited. When setting the observation positions at n positions, the cameras for imaging capture images with n + 1 cameras that are spaced horizontally in consideration of parallax. The images sequentially captured from the cameras installed on the right side are A 1 , A 2 , A 3 , ···, A n+1(Let \(n\) be a natural number.) In this case, a block with \(n + 1\) reflection regions is fabricated on the transparent resin plate 20, and this block is formed in a matrix shape. In each reflection region, images \(A\) 1 , \(A\) 2 , \(A\) 3 , ···, \(A\) n+1 are assigned respectively. In each reflection region, observation positions \(\alpha\) 1 , \(\alpha\) 2 , \(\alpha\) 3 , ···, \(\alpha\) n (Let \(n\) be a natural number.) are set in order from the rightmost side. For each observation position \(\alpha\) 1 , \(\alpha\) 2 , \(\alpha\) 3 , ···, \(\alpha\) n , the viewpoints of the right eye corresponding thereto are \(\beta\) 1 , \(\beta\) 2 , \(\beta\) 3 , ···, \(\beta\) n , and the viewpoints of the left eye are \(\beta\) 2 , \(\beta\) 3 , \(\beta\) 4 , ···, \(\beta\) n+1 . When this is the case, reflection grooves may be formed respectively so that the image \(A\) n is reflected on \(\beta\) n . By adopting such a configuration, for example, an observer \(\alpha\) 5 at the fifth observation position from the right will recognize the right-eye image of \(A\) 5 and the left-eye image of \(A\) 6 .

[0048] (Fourth Embodiment) The transparent resin plate 20 of the display device 100 according to the fourth embodiment is shown in FIG. 15. The fourth embodiment is applicable when, in the first embodiment or the second embodiment, in the column direction, the entire matrix is formed by all right-eye reflection grooves 21 or left-eye reflection grooves 22, and in the row direction, the right-eye reflection grooves 21 and the left-eye reflection grooves 22 are provided alternately. The transparent resin plate 20 according to the fourth embodiment is formed so as to reciprocate at high speed within a certain range \(\delta\) vertically as shown in FIG. 15.

[0049] By moving it up and down at high speed in this way, the image of the projector 10 can be reflected on the entire surface that passes through due to the up and down movement. When moving at high speed, the human eye can recognize the entire passing surface due to the afterimage phenomenon. This movement can fill the gaps between the right-eye reflection grooves 21 or the left-eye reflection grooves 22 adjacent vertically, can enlarge the reflection area of the image, and can extremely reduce the area where the image is not reflected.

[0050] The display device according to the above-described first to fourth embodiments can be used as various display devices such as a display device for the effect of a gaming machine. By incorporating it into a pachinko gaming machine or a rotary gaming machine, it is possible to perform an effect such that a character pops out from a liquid crystal display arranged on the back side and floats in the air in front, or to perform an effect such that an accessory is covered with an effect when the accessory appears.

[0051] In the above-described embodiments, an example in which the reflection grooves are formed on the back side has been described. However, the reflection grooves may be provided only on the front side, or may be provided on both the front side and the back side. Similar to the back side, the groove angle of the reflection grooves provided on the front side is set so that an image is reflected at the viewpoints of the right eye or the left eye.
