Description

The present invention relates to a presentation device installed in an amusement machine or the like, and more specifically to a presentation device that allows input of instructions.

Conventionally, there is a technology in which grooves or other shapes are applied to the front and back of a light guide plate along with a design such as letters or figures, and light is then incident from the end face of the light guide plate to illuminate and display the applied design. As the light that enters the inside of the light guide plate from the end face is propagated while repeatedly undergoing total reflection, some of the light is reflected by the uneven surfaces caused by the shape, changing the light path, and is emitted from the surface (exit surface) of the light guide plate, contributing to the display. Gaming machines (such as pachinko machines, slot machines, gaming machines, etc.) installed in game arcades are equipped with performance devices using this technology.

One such example is a gaming machine equipped with a display unit that uses a light guide plate (see, for example, Patent Document 1). In this gaming machine, reels are provided inside the housing, and the reel patterns can be seen through a display window provided on the front side of the housing. The display unit is disposed below the reels, and the content of the effects provided by the display unit can be seen through a window portion on the housing side located below the display window.

Here, the display unit has, inside the case, multiple light guide plates with a design, multiple light sources arranged corresponding to the multiple light guide plates, and a reflecting mirror. The light guide plates and the corresponding light sources constitute an optical device that displays a flat image. The multiple optical devices are arranged by stacking the light guide plates. The reflecting mirror is installed above the multiple optical devices with the mirror surface facing downward at a predetermined angle of about 45° to the emission surface. The case is formed with a window that becomes the display area, and the display unit is installed so that the window faces the window on the cabinet side of the gaming machine.

In this configuration, the design displayed on the multiple light guide plates is reflected by the reflecting mirror and guided to the window of the case, where it is visible to the player through the window on the cabinet side. By changing the light devices that are lit up or the combination of these devices, the content of the display that is visible to the player can be one of the multiple designs displayed on the multiple light guide plates, or a combination of multiple designs.

Also, conventionally, optical devices are known that use a single light guide plate to allow an observer to visually recognize a three-dimensional image (a three-dimensional picture) by devising a shape for the light guide plate (for example, Patent Document 2). In this optical device, the light guide plate guides incident light and emits it from an exit surface, and the light that has been redirected and emitted from the exit surface is recognized as a three-dimensional image by the observer.

In the case of presentation devices such as the display units described above, if the presentation devices are capable of accepting command inputs from the player, the player's interest can be further enhanced. Furthermore, in recent years, there has been an increasing demand for contactless command inputs as a measure against infectious diseases.

In order to meet such demands, one aspect of the present invention aims to realize a performance device that can accept operations without contact.

In order to solve the above problems, the production device according to one aspect of the present invention adopts the following configuration.

That is, a push performance device according to one aspect of the present invention includes a first display unit, a mirror that reflects an image displayed on the first display unit and guides it to a display area, a second display unit that displays a three-dimensional image of an object to be operated on in the display area, including a first optical device having a light guide plate that guides incident light and emits it from an exit surface, and the light that has been changed in light path and emitted from the exit surface is recognized as a three-dimensional image by an observer, and an operation detection unit that detects operations on the three-dimensional image displayed on the second display unit.

According to the above configuration, a three-dimensional image of the object to be operated is displayed on the second display unit in the display area where the effect displayed on the first display unit is visually recognized, and the operation detection unit detects the player's operation on the three-dimensional image. This makes it possible to accept the player's instruction input without contact.

In the push performance device according to one aspect described above, the mirror may be a cold mirror that transmits infrared light and reflects visible light, and the operation detection unit may include an infrared active sensor and be arranged on the rear side of the cold mirror.

According to the above configuration, an infrared active sensor is used for the operation detection unit, and a cold mirror is used for the mirror, with the infrared active sensor installed on the back side of the mirror. This allows operations on the stereoscopic image to be detected with high accuracy without being affected by the first display unit. In addition, since the operation detection unit can be placed inside the performance device, the performance device can be unitized.

In the push performance device according to one aspect described above, the first display unit may be configured to include a plurality of second optical devices having a light guide plate that guides incident light and emits it from an exit surface, and the light that has been changed in its optical path and is emitted from the exit surface can be recognized as a planar image by an observer. This allows the display to change, and allows the player to view a bright planar image.

In the push effect device according to one aspect described above, the second display unit may be configured to include, as the first light device, a first light device that displays a three-dimensional image of the object to be operated before it is operated, and a first light device that displays a three-dimensional image of the object to be operated after it is operated. This allows the player to feel a clearer sense of feedback when operating the three-dimensional image, even though it is non-contact.

In the push effect device according to the above aspect, the first display unit can be configured as a liquid crystal display device. This allows any content to be displayed without being limited to the content displayed.

According to one aspect of the present invention, it is possible to realize a performance device that can accept operations without contact.

FIG.

Below, an embodiment according to one aspect of the present disclosure (hereinafter also referred to as "the present embodiment") will be described with reference to the drawings. In this embodiment, as one aspect of the presentation device of the present disclosure, a pachinko slot machine is exemplified as an amusement machine, and a configuration in which a presentation unit is mounted on the amusement machine that is a pachinko slot machine is exemplified.

§1 Application Example First, an example of a scene in which the presentation device is applied will be described with reference to Figures 1, 2, 3, and 5. As shown in Figures 1 and 2, a presentation unit 10 according to a first embodiment, which is an example of a presentation device, is installed inside the cabinet 3 of a gaming machine 1 in an empty space in front of and below the reel 2. The presentation unit 10 performs presentation using light that displays patterns, characters, etc., and also accepts instruction inputs from the player.

As shown in Figures 3 and 4, the presentation unit 10 includes a first display unit 12, a second display unit 13, a mirror 14, and an operation detection unit 15 inside a case 11. The first display unit 12 includes a plurality of planar light devices 16 each equipped with a light guide plate 17, and the display is reflected by the mirror 14 and guided to a display area 19. The display area 19 faces the window 7 of the gaming machine 1, and the player can view the display of the first display unit 12 through the window 7.

The second display unit 13 includes a stereoscopic light device (first light device) 20 that displays a stereoscopic image 25 of the object to be operated. The stereoscopic light device 20 is disposed inside the display area 19, and the stereoscopic image 25 is visually recognized as protruding from the gaming machine 1 through the display area 19 and the window portion 7. The player operates the stereoscopic image 25 to input instructions without contact. The operation detection unit 15 detects the player's operation on the stereoscopic image 25. Here, by providing the operation detection unit 15 inside the case 11, the presentation device can be unitized.

In the first to third embodiments, the operation detection unit 15 includes an infrared active sensor 23, and the mirror 14 is a cold mirror that reflects visible light and transmits infrared light. The infrared active sensor 23 detects the space where the three-dimensional image 25 is formed, or a space a predetermined distance away from the position where the three-dimensional image 25 is formed, as its detection area. Infrared light is irradiated onto the detection area, and when a player's finger or the like is present in the area, the reflected infrared light is received and the operation is detected.

The mirror 14 is a cold mirror that reflects visible light and transmits infrared light, so the operation detection unit 15 can be installed on the back side of the mirror 14. This allows operations to be detected with high accuracy without being affected by the shapes 40 (see FIG. 7) formed on the multiple light guide plates of the first display unit 12.

The operation detection unit 15 may be installed outside the performance device (see FIG. 10). The first display unit 12 may use a liquid crystal display device 51 or the like instead of the multiple planar optical devices 16 (see FIG. 9).

§2 Configuration Example [Embodiment 1]
(1. Overview of Gaming Machine 1)
FIG. 1 is a front view of a gaming machine 1 on which a presentation unit 10 according to the first embodiment is mounted. FIG. 2 is a side view of the gaming machine 1 on which a presentation unit 10 according to the first embodiment is mounted. As shown in FIG. 1 and FIG. 2, the gaming machine 1 includes a reel 2 inside a cabinet 3, and has a display window 4 on the front side of the cabinet 3. The patterns on the reel 2 can be seen through the display window 4. Below the display window 4, a start lever 5 for rotating the reel 2 and a three-way switch 6 for stopping the rotating reel 2 are arranged. A window 7 is provided between the display window 4 and the three-way switch 6, and a display area 19 of the presentation unit 10 can be seen through the window 7.

As shown in FIG. 2, the presentation unit 10 is installed inside the cabinet 3 in the empty space in front of and below the reels 2. The presentation unit 10 performs presentations using light to display patterns, letters, etc., and also accepts instruction inputs from the player. The configuration of the presentation unit 10 will be described in detail below.

(2. Configuration of Production Unit 10)
3 is a schematic diagram showing the configuration of the rendering unit 10 according to the first embodiment, and shows the configuration inside the case 11 as viewed from the side of the rendering unit 10. As shown in FIG. 3, the rendering unit 10 includes a first display unit 12, a second display unit 13, a mirror 14, and an operation detection unit 15 inside the case 11.

(2-1. First display section 12)
In this embodiment, the first display unit 12 includes a plurality of planar optical devices (second optical devices) 16 that allow light emitted from the exit surface of a light guide plate 17 to be recognized as a planar image by a player (observer). The planar optical device 16 has a light guide plate 17 that guides incident light and emits it from an emission surface, and a light source 18 that is disposed opposite an end face of the light guide plate 17 and supplies light to the light guide plate 17 .

The light guide plate 17 is a transparent thin plate member made of a light-transmitting material such as acrylic resin or glass. Note that the light guide plate 17 does not necessarily have to be colorless and transparent, and may be translucent or colored.

The front or rear surface of the light guide plate 17 is provided with grooves or other patterns 40 (see FIG. 7) that follow designs such as letters or figures. As light that enters the light guide plate 17 from the end face is propagated while repeatedly being totally reflected, some of the light is reflected by the uneven surfaces of the patterns 40, changing the light path, and is emitted from the front surface (exit surface) of the light guide plate 17. The design formed by the patterns 40 is displayed as a two-dimensional image by the emitted light, and can be viewed.

The light source 18 is, for example, an LED (Light Emitting Diode), and may be a full-color LED that can change color. In order to make light uniformly incident from the end face of the light guide plate 17, a plurality of light sources 18 may be installed on one end face. In addition, a scattering plate that scatters the light of the light source 18 may be provided, and the light emitted from the light source 18 may be scattered to increase uniformity before being incident on the light guide plate 17.

In addition, the light guide plate 17 may be shaped to have different designs for light traveling in different directions, and the light sources 18 may be installed on multiple end faces with different traveling directions. In this way, by switching the light source to be turned on, different designs can be displayed using a single light guide plate (a single planar optical device).

In this embodiment, the first display unit 12 includes four such planar optical devices 16. Each planar optical device 16 is installed so that its light guide plate 17 is stacked. Hereinafter, when it is necessary to distinguish the four planar optical devices 16 from one another, the one at the bottom will be referred to as planar optical device 16a, and in the order from planar optical device 16a to the top, they will be referred to as planar optical device 16b, planar optical device 16c, and planar optical device 16d. Similarly, when it is necessary to distinguish them from one another, the light source 18 of planar optical device 16a will be referred to as light source 18a, the light guide plate 17 of planar optical device 16a will be referred to as light guide plate 17a, and the same will be applied to the other planar optical devices 16b to 16d.

Figure 4 is an explanatory diagram showing an example of a pattern displayed by turning on the four planar light devices 16a to 16d of the first display section 12 in the performance unit 10 according to the first embodiment. The diagram with reference numeral 1001 shows the pattern displayed when the planar light device 16a is turned on, and the diagram with reference numeral 1002 shows the pattern displayed when the planar light device 16b is turned on. The diagram with reference numeral 1003 shows the pattern displayed when the planar light device 16c is turned on, and the diagram with reference numeral 1004 shows the pattern displayed when the planar light device 16d is turned on. The diagram with reference numeral 1005 shows the pattern displayed when all four planar light devices 16a to 16d are turned on.

On the back or front of the light guide plates 17a to 17d of the four planar light devices 16a to 16d, patterns indicated by reference numerals 1001 to 1004, respectively, are formed by unevenness due to grooves or other shapes 40 (see FIG. 7). As indicated by reference numeral 1005, patterns can be combined by lighting up multiple planar light devices 16. In addition, by stacking the four planar light devices 16a to 16d with a gap between each other, a sense of depth can be created in the patterns displayed when all of them are lit up.

(2-2. Mirror 14)
Returning to Fig. 3, the mirror 14 is a member that reflects the image (planar image) displayed on the first display unit 12 and guides it to the display area 19. In this embodiment, the mirror 14 is a cold mirror that reflects visible light and transmits infrared light. The mirror 14 is installed above the multiple planar optical devices 16 with the mirror surface facing downward at a predetermined angle of about 45° with respect to the emission surfaces of the multiple light guide plates 17. The display area 19 is a window portion consisting of a transparent portion or an opening formed in the case 11, and the performance unit 10 is installed so that the display area 19 faces the window portion 7 of the gaming machine 1.

(2-3. Second display section 13)
The second display unit 13 includes a stereoscopic optical device (first optical device) 20 that displays a stereoscopic image 25 of an operation target in a display area 19. The stereoscopic optical device 20 guides incident light and emits the light from an exit surface. The stereoscopic optical device 20 includes a light guide plate 21 that guides a stereoscopic image and a light source 22 that is disposed opposite an end surface of the light guide plate 21 and supplies light to the light guide plate 21. The stereoscopic optical device 20 is located inside the display area 19 and displays a stereoscopic image. 25 is disposed in a position where it can be visually recognized as protruding from the gaming machine 1 through the display area 19 and the window portion 7.

Light guide plate 21 is made of the same material as light guide plate 17, but differs in that it is shaped to allow a three-dimensional image to be perceived. The light that has its optical path changed in light guide plate 21 and is emitted from the exit surface is perceived as a three-dimensional image by the player (observer).

More specifically, on the back side of the light guide plate 21, a plurality of prisms (not shown) are provided, which are formed as triangular prism-shaped grooves and arranged at different positions for each point of the three-dimensional image 25 displayed in the air. One surface of each prism faces the light source 22 and is formed as a reflecting surface that totally reflects the light that enters from the end surface (incident surface) facing the light source 22 and propagates inside the light guide plate 21 toward the front side where the display area 19 is located. Each of these multiple prisms is arranged to reflect the light that enters from the incident surface and propagates inside the light guide plate 21 toward each point of the three-dimensional image 25. As a result, the light from the multiple prisms arranged at different positions is concentrated on each point of the three-dimensional image displayed in the air. Therefore, from the player positioned at the front side, it appears that light is emanating from each point of the three-dimensional image displayed in the air, and the three-dimensional image displayed in the air is observed. Note that displaying an image observed as a three-dimensional image is also expressed as displaying a three-dimensional image.

The light source 22 is, for example, an LED (Light Emitting Diode) like the light source 18 described above, and may be a full-color LED whose color can be changed. A plurality of light sources may be installed on one end face to allow light to be uniformly incident from the end face of the light guide plate 21. A scattering plate that scatters the light from the light source 22 may also be provided, and the light emitted from the light source 22 may be scattered to increase uniformity before being incident on the light guide plate 21.

(2-4. Operation detection unit 15)
The operation detection unit 15 detects the player's operation with respect to the three-dimensional image 25 displayed on the second display unit 13. In this embodiment, the operation detection unit 15 includes an infrared active sensor 23, and is installed on the rear side of the mirror 14. The infrared active sensor 23 irradiates infrared rays toward the space where the three-dimensional image 25 is formed. The mirror 14, which is made of a cold mirror, transmits the infrared rays, and the infrared rays reach the space where the three-dimensional image 25 is formed. The infrared rays that have reached the space are reflected if a player's finger or the like is present in the space or in a space a predetermined range away from the position where the three-dimensional image 25 is formed, and pass through the mirror 14 and return to the infrared active sensor 23.

The infrared active sensor 23 detects reflected light of the irradiated infrared light, thereby detecting an object in the space where the stereoscopic image 25 is formed, or in a space a predetermined range away from the position where the stereoscopic image 25 is formed. The space where the stereoscopic image 25 is formed, or the space a predetermined range away from the position where the stereoscopic image 25 is formed, is the detection area of the operation detection unit 15.

(3. Control device 30 of performance unit 10)
5 is a block diagram showing the main parts of the control system of the gaming machine 1 equipped with the rendering unit 10 according to the embodiment 1. The control device 30 is a computer device constituted by an arithmetic processing unit such as a CPU (Central Processing Unit) or a dedicated processor, and controls the operation of each part of the gaming machine 1 including the rendering unit 10.

When the operation detection unit 15 detects an operation on the three-dimensional image 25, the control device 30 switches the image displayed on the first display unit 12. A specific example of switching the image displayed on the first display unit 12 is turning on, off, or blinking one or more predetermined planar light devices 16 out of the four planar light devices 16a to 16d depending on the status of the game being played on the gaming machine 1. The control device 30 may use the detection of an operation on the three-dimensional image 25 by the operation detection unit 15 for a presentation device of the gaming machine 1 other than the presentation unit 10.

(4. Operation of the Production Unit 10)
6 is an explanatory diagram showing the operation of the performance unit 10 according to the first embodiment. As shown in FIG. 6, the control device 30 lights up one or more of the planar light devices 16a to 16d of the first display unit 12, so that the first display unit 12 displays the patterns as shown by the reference numerals 1001 to 1005 in FIG. 4. Since the patterns displayed on the first display unit 12 are visible light, they are reflected by the mirror 14, transmitted through the light guide plate 21 of the second display unit 13, reach the display area 19, and are visually recognized by the player through the window unit 7 of the gaming machine 1 (thick solid arrow in FIG. 6).

When the control device 30 turns on the stereoscopic light device 20 in the second display unit 13, a stereoscopic image 25 is displayed in the display area 19 on the second display unit 13, as shown in FIG. 6. The stereoscopic image 25 is visually recognized (observed) by the player so as to protrude toward the player through the display area 19 and the window 7 of the gaming machine 1. As shown in the examples of FIGS. 3 and 6, by making the stereoscopic image 25 a thick push button switch, the player is explicitly informed that he or she needs to press the corresponding part in space. Of course, the stereoscopic image 25 is not limited to this and may be of any type.

The first display unit 12 and the second display unit 13 can be turned on simultaneously. This allows the stereoscopic image 25 to be displayed superimposed on the display content of the first display unit 12 displayed in the display area 19.

While the stereoscopic light device 20 in the second display unit 13 is turned on, the control device 30 turns on the infrared active sensor 23 in the operation detection unit 15 to detect operations on the stereoscopic image 25. Infrared rays emitted from the infrared active sensor 23 pass through the mirror 14 and the light guide plate 21 in the second display unit 13 to reach the detection area. When a player brings a finger or the like close to the detection area to operate the stereoscopic image 25, the infrared rays are reflected, pass through the light guide plate 21 and mirror 14, and are received by the infrared active sensor 23 (dashed double-headed arrow in FIG. 6).

When reflected infrared light is received by the infrared active sensor 23, the control device 30 determines that a command has been input by the player, and, for example, switches the image displayed on the first display unit 12.

(5. Effects)
In the presentation unit 10 according to the first embodiment, a three-dimensional image of an object to be operated is displayed on the second display unit 13 and is viewed through the window unit 7 that allows the viewer to view the presentation displayed on the first display unit 12, and the operation detection unit 15 detects the player's operation on the three-dimensional image. This allows the player to input instructions in a non-contact manner without touching the gaming machine 1.

In addition, an infrared active sensor 23 is used, and a cold mirror is used as the mirror 14, with the infrared active sensor 23 installed on the rear side of the mirror 14. This allows operations on the stereoscopic image 25 to be detected with high accuracy without being affected by the first display unit 12. In addition, the operation detection unit 15 can be placed inside the case 11, making it possible to form it into a unit.

Here, using FIG. 7, we will explain the configuration of a comparative example in which a cold mirror is not used as the mirror 14, and the infrared active sensor 23 is placed below (behind) the first display unit 12. FIG. 7 is an explanatory diagram showing the optical path of infrared rays in the configuration of the comparative example.

As shown in FIG. 7, when the infrared active sensor 23 is placed below the first display unit 12, the infrared light emitted from the infrared active sensor 23 passes through the multiple light guide plates 17a to 17d and reaches the detection area of the operation detection unit 15 where the stereoscopic image 25 is formed. The same is true on the return path, where the reflected infrared light passes through the multiple light guide plates 17a to 17d in the reverse order to the outward path and returns to the infrared active sensor 23.

Ideally, the optical path of such infrared rays would pass through the parts where the shapes 40 are not applied, as shown by the dashed lines in the figure. However, because the parts where the shapes 40 are formed on the multiple light guide plates 17a to 17d vary depending on the design, it is difficult to position the infrared active sensor 23 so that the optical path does not pass through the shapes 40. As a result, the infrared rays are affected by the shapes 40 and follow the optical path shown by the thick lines in the figure, reducing the accuracy of detecting operations on the three-dimensional image 25.

Moreover, in the configuration of this comparative example, there is a risk that the infrared active sensor 23 arranged below may be visible through the multiple light guide plates 17a to 17d. In contrast, in the configuration of this embodiment, the infrared active sensor 23 is arranged on the rear side of the mirror 14, so the infrared active sensor 23 is not visible.

[Embodiment 2]
Other embodiments of the present invention will be described below. For the sake of convenience, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

Figure 8 is a schematic diagram showing the configuration of the rendering unit 10A in embodiment 2, with the internal configuration of the case 11 viewed from the side of the rendering unit 10A. As shown in Figure 8, the rendering unit 10A differs from the rendering unit 10 in that the second display section 13 has two stereoscopic light devices 20.

Specifically, the stereoscopic light device (first light device) 20 that allows the user to view the stereoscopic image 25 of the above-mentioned push button switch is designated as stereoscopic light device 20a, and the device further includes stereoscopic light device 20b that allows the user to view a stereoscopic image 26 of the push button switch in a pressed state. Stereoscopic light device 20a corresponds to the first light device that displays a stereoscopic image of the object to be operated before it is operated, and stereoscopic light device 20b corresponds to the first light device that displays a stereoscopic image of the object to be operated after it is operated.

The control device 30 turns on the stereoscopic light device 20a to display the stereoscopic image 25 in the display area 19. When the infrared active sensor 23 detects an operation on the stereoscopic image 25, the control device 30 determines that the player has operated the stereoscopic image 25, and turns off the stereoscopic light device 20a and turns on the stereoscopic light device 20a. This causes the display area 19 to display the stereoscopic image 26 in a pressed state, instead of the stereoscopic image 25. The control device 30 may switch the display on the second display unit 13 in this manner and also switch the display on the first display unit 12. In this configuration, the player can be given a clearer sense of feedback when operating the stereoscopic image 25, even though it is non-contact.

Third Embodiment
Other embodiments of the present invention will be described below. For the sake of convenience, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

Figure 9 is a schematic diagram showing the configuration of the performance unit 10B according to embodiment 3, with the internal configuration of the case 11 viewed from the side of the performance unit 10B. As shown in Figure 9, the performance unit 10B has a first display unit 12 equipped with a liquid crystal display device 51 instead of multiple planar light devices (second light devices) 16. Although the display of the planar light device 16 using a light guide plate 17 has the advantage of high brightness, the content that can be displayed is fixed. In contrast, by using a liquid crystal display device 51 for the first display unit 12, any planar image can be displayed in the display area 19.

In the case of the liquid crystal display device 51, if a normal mirror that reflects infrared light as well as visible light is used as the mirror 14, the infrared active sensor 23 must be installed on the display surface side of the liquid crystal display device 51, which creates the problem of interfering with the display of the liquid crystal display device 51. However, as described above, by using a cold mirror as the mirror 14 and arranging the infrared active sensor 23 on its back side, it is possible to detect operations with the infrared active sensor 23 without interfering with the display of the liquid crystal display device 51.

§3 Modifications Although the embodiment of the present invention has been described above in detail, the above description is merely an example of the present invention in every respect. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. For example, the following modifications are possible. In the following, the same reference numerals are used for the same components as in the above embodiment, and the description of the same points as in the above embodiment is omitted as appropriate. The following modifications can be combined as appropriate.

1) In the above-described embodiment, an example was shown in which multiple planar optical devices (second optical devices) 16 or a liquid crystal display device 51 were used in the first display unit 12, but one or more planar optical devices 16 may be set on the display surface side of the liquid crystal display device 51. Also, instead of the liquid crystal display device 51, a configuration may be used in which a display device of a self-luminous device such as an OLED (Organic Light Emitting Diode) is provided.

2) If the gaming machine does not have a reel 2 and space is available to install a presentation unit, a hot mirror that reflects infrared light and transmits visible light may be used as the mirror 14 instead of a cold mirror. In this case, an infrared active sensor 23 is placed below the mirror surface, and the first display unit 12 is disposed on the back side of the mirror 14.

3) In the embodiment described above, the operation detection unit 15 is configured to include an infrared active sensor 23, and the operation detection unit 15 is housed inside the performance units 10 to 10B to form a unit. However, the operation detection unit 15 may also be configured to be provided externally, separate from the performance units 10 to 10B. In that case, various sensors can be used, such as a light-emitting and receiving sensor, in addition to the infrared active sensor 23.

Figure 10 is an explanatory diagram showing the main parts of a gaming machine 1D equipped with a modified rendering device 10D. Although not shown, the rendering device 10D has a first display unit 12 and a second display unit 13 inside a case 11. The difference from the rendering units 10 to 10C described above is that it has a normal mirror that reflects both visible light and infrared light as the mirror 14, and that the operation detection unit 15 is provided outside the device.

In the example of FIG. 10, the operation detection unit 15 includes a light projecting/receiving sensor 41. The light projecting/receiving sensor 41 includes a light projecting unit 41a and a light receiving unit 41b. The light projecting unit 41a projects light toward the light receiving unit 41b, which receives the projected light. When an object blocks the light, the amount of light received by the light receiving unit 41b decreases, and the control device 30 detects the presence of an object in the light path. The light projecting/receiving sensor 41 is installed so that the space in which the stereoscopic image 25 is formed by the second display unit 13 described above, or a space a predetermined distance away from the position where the stereoscopic image 25 is formed, is included in the light path.

When the operation detection unit 15 is provided outside the device, any sensor capable of non-contact detection can be used, not limited to the light emitting/receiving sensor 41. For example, a motion sensor, a capacitance sensor, etc. can be used.

[Software implementation example]
The control block of the control device 30 may be realized by a logic circuit (hardware) formed on an integrated circuit (IC chip) or the like, or may be realized by software.

In the latter case, the control device 30 includes a computer that executes the instructions of a program, which is software that realizes each function. This computer includes, for example, one or more processors, and a computer-readable recording medium that stores the program. The object of the present invention is achieved by the processor reading the program from the recording medium and executing it in the computer. The processor can be, for example, a CPU (Central Processing Unit). The recording medium can be a "non-transient tangible medium," such as a ROM (Read Only Memory), tape, disk, card, semiconductor memory, programmable logic circuit, etc. The computer can also include a RAM (Random Access Memory) that expands the program. The program can be supplied to the computer via any transmission medium (such as a communication network or broadcast waves) that can transmit the program. One aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The technical scope of the present invention also includes embodiments obtained by appropriately combining the technical means disclosed in different embodiments.
