Description

[Technical field]

[0001] The present invention relates to an effect device mounted on a gaming machine or the like, and more particularly to an effect device capable of inputting instructions. [Background technology]

[0002] Conventionally, there is a technology in which grooves or other shapes are applied to the front and back surfaces of a light guide plate along with designs such as letters and figures, and light is made to enter from the end faces 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 faces 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 that use such technology.

[0003] One such known gaming machine is equipped with a display unit using a light guide plate (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.

[0004] Here, the display unit has, inside the case, a plurality of light guide plates with a design, a plurality of light sources arranged corresponding to the plurality of 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 plurality of optical devices are arranged by stacking the respective light guide plates. The reflecting mirror is installed above the plurality of optical devices with the mirror surface facing downward at a predetermined angle of about 45° with respect to the emission surface. The case is formed with a window portion that becomes the display area, and the display unit is installed so that the window portion faces the cabinet side window portion of the gaming machine.

[0005] In such a configuration, the display of the design applied to the multiple light guide plates is reflected by the reflecting mirror and guided to the window of the case, and is visually recognized by the player through the window on the cabinet side. The content of the display visually recognized by the player can be one of the multiple designs applied to the multiple light guide plates or a combination of multiple designs by changing the light devices to be lit or the combination thereof.

[0006] Also, conventionally, optical devices are known that allow an observer to visually recognize a stereoscopic image (a three-dimensional picture) using a single light guide plate by devising a shape for the light guide plate (for example, Patent Document 2). In this optical device, the light guide plate includes a light guide plate that 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 stereoscopic image by the observer.

[0007] [Patent Document 1] JP 2016-174814 A [Patent Document 2] JP 2018-151556 A Summary of the Invention [Problem to be solved by the invention]

[0008] In the above-mentioned display unit and other presentation devices, if the presentation devices are capable of receiving command inputs from the player, the player's interest can be further enhanced. In recent years, there has been an increasing demand for contactless command inputs as a measure against infectious diseases.

[0009] In order to meet such demands, one aspect of the present invention aims to realize a performance device that can accept operations in a non-contact manner. [Means for solving the problem]

[0010] In order to solve the above problems, a rendering device according to one aspect of the present invention employs the following configuration.

[0011] That is, a push performance device according to one aspect of the present invention comprises 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, the second display unit including a first optical device having a light guide plate that guides incident light and emits it from an exit surface, the light path of which is changed and the light that exits from the exit surface is recognized as a three-dimensional image by an observer, and an operation detection unit that detects operations performed on the three-dimensional image displayed on the second display unit.

[0012] According to the above configuration, a three-dimensional image of an operation target displayed on the second display unit is visually recognized in the display area where the effect displayed on the first display unit is visually recognized, and the operation detection unit detects the operation of the player with respect to the three-dimensional image. This makes it possible to accept the instruction input from the player in a non-contact manner.

[0013] In the push performance device relating to the above-mentioned aspect, 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 configured to be arranged on the back side of the cold mirror.

[0014] 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 the operation on the stereoscopic image to be detected with high accuracy without being affected by the first display unit. In addition, the operation detection unit can be placed inside the production device, allowing the production device to be unitized.

[0015] In the push effect device according to the above aspect, the first display unit may be configured to include a plurality of second optical devices each having a light guide plate that guides incident light and emits it from an emission surface, and the light that has been changed in optical path and emitted from the emission surface is recognized as a planar image by an observer. This allows the display to change and allows the player to visually recognize a planar image with high brightness.

[0016] In the push performance device according to the above aspect, the second display unit may include, as the first light device, a first light device that displays a three-dimensional image of the operation target before operation, and a first light device that displays a three-dimensional image of the operation target after operation. This allows the player to feel a clearer sense of feedback when operating the three-dimensional image, even though it is non-contact.

[0017] In the push performance device according to the above aspect, the first display unit may be a liquid crystal display device, whereby the display content is not limited and any content can be displayed. Effect of the Invention

[0018] According to one aspect of the present invention, a presentation device capable of accepting operations in a non-contact manner can be realized. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, 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 slot machine is exemplified as a gaming machine, and a configuration in which a presentation unit is mounted on the slot machine is exemplified.

[0021] §1 Examples of application 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 symbols, characters, etc., and also accepts instruction inputs from the player.

[0022] 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 optical 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.

[0023] The second display unit 13 includes a stereoscopic light device (first light device) 20 that displays a stereoscopic image 25 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 unit 7. The player operates the stereoscopic image 25 to input instructions in a non-contact manner. 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 performance device can be unitized.

[0024] 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 stereoscopic image 25 is formed, or a space a predetermined distance away from the position where the stereoscopic 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.

[0025] Since mirror 14 is a cold mirror that reflects visible light and transmits infrared light, it is possible to install operation detection unit 15 on the back side of mirror 14. This makes it possible to detect operations with high accuracy without being affected by shapes 40 (see FIG. 7) formed on the multiple light guide plates of first display unit 12.

[0026] 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).

[0027] §2 Configuration example [First embodiment] (1. Overview of Gaming Machine 1) FIG. 1 is a front view of a gaming machine 1 equipped with a presentation unit 10 according to the first embodiment. FIG. 2 is a side view of the gaming machine 1 equipped with a presentation unit 10 according to the first embodiment. As shown in FIGS. 1 and 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.

[0028] As shown in Fig. 2, the production unit 10 is installed inside the cabinet 3 in an empty space on the front side below the reel 2. The production unit 10 performs production using light to display symbols, characters, etc., and also accepts instruction inputs from the player. The configuration of the production unit 10 will be described in detail below.

[0029] (2. Composition of Production Unit 10) 3 is a schematic diagram showing the configuration of the production unit 10 according to the first embodiment, and shows the internal configuration of the case 11 as viewed from the side of the production unit 10. As shown in FIG. 3, the production 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.

[0030] (2-1. 1st display section 12) In this embodiment, the first display unit 12 includes a plurality of planar optical devices (second optical devices) 16 in which light emitted from an exit surface of a light guide plate 17 is recognized as a planar image by a player (observer). The planar optical device 16 includes a light guide plate 17 that guides incident light and emits it from the exit 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.

[0031] The light guide plate 17 is a transparent thin plate member made of a light-transmitting material such as acrylic resin, glass, etc. The light guide plate 17 does not necessarily have to be colorless and transparent, and may be translucent or colored.

[0032] The front or rear surface of the light guide plate 17 is provided with grooves or other such patterns 40 (see FIG. 7) along with designs such as letters and figures. As light that enters the inside of the light guide plate 17 from the end face is propagated while repeatedly undergoing total reflection, some of the light is reflected by the uneven surfaces of the patterns 40, etc., and the light path is changed, and the light 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 is visually recognized.

[0033] The light source 18 is, for example, an LED (Light Emitting Diode), and may be a full-color LED capable of changing color. In order to uniformly introduce light from the end face of the light guide plate 17, a plurality of light sources 18 may be provided on one end face. A scattering plate for scattering the light from the light source 18 may be provided, and the light emitted from the light source 18 may be scattered to improve uniformity before being introduced into the light guide plate 17.

[0034] Also, different designs may be formed on the light guide plate 17 for light traveling in different directions, and the light sources 18 may be installed on a plurality of 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 (single planar optical device).

[0035] In this embodiment, the first display unit 12 includes four such planar optical devices 16. The planar optical devices 16 are arranged so that their light guide plates 17 are stacked. Hereinafter, when it is necessary to distinguish the four planar optical devices 16 from one another, the one at the bottom layer will be referred to as the planar optical device 16a, and in the order from the planar optical device 16a to the top layer, the planar optical device 16b, the planar optical device 16c, and the planar optical device 16d will be referred to. Similarly, when it is necessary to distinguish the four planar optical devices from one another, the light source 18 of the planar optical device 16a will be referred to as the light source 18a, the light guide plate 17 of the planar optical device 16a will be referred to as the light guide plate 17a, and the same will be applied to the other planar optical devices 16b to 16d.

[0036] 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 unit 12 in the production unit 10 according to the first embodiment. The diagram with the reference numeral 1001 shows a pattern displayed when the planar light device 16a is turned on, and the diagram with the reference numeral 1002 shows a pattern displayed when the planar light device 16b is turned on. The diagram with the reference numeral 1003 shows a pattern displayed when the planar light device 16c is turned on, and the diagram with the reference numeral 1004 shows a pattern displayed when the planar light device 16d is turned on. The diagram with the reference numeral 1005 shows a pattern displayed when all four planar light devices 16a to 16d are turned on.

[0037] Patterns indicated by reference numerals 1001 to 1004, respectively, are formed on the rear or front surfaces of the light guide plates 17a to 17d of the four planar optical devices 16a to 16d by means of unevenness formed by grooves or other shapes 40 (see FIG. 7). As indicated by reference numeral 1005, patterns can be combined by lighting up a plurality of planar optical devices 16. In addition, by stacking the four planar optical devices 16a to 16d with gaps between each other, a sense of depth can be created in the patterns displayed when all of the planar optical devices are lit up.

[0038] (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.

[0039] (2-3.Second display section 13) The second display unit 13 includes a stereoscopic light device (first light device) 20 that displays a stereoscopic image 25 of the operation target in the display area 19. The stereoscopic light device 20 has a light guide plate 21 that guides incident light and emits it from an exit surface, and a light source 22 that is disposed opposite an end face of the light guide plate 21 and supplies light to the light guide plate 21. The stereoscopic light device 20 is disposed inside the display area 19 at a position where the stereoscopic image 25 is visually recognized as protruding from the gaming machine 1 through the display area 19 and the window portion 7.

[0040] The light guide plate 21 is made of the same material as the light guide plate 17, but is different in that it is shaped to allow a stereoscopic image to be recognized. The light that has been changed in the light guide plate 21 and is emitted from the emission surface is recognized as a stereoscopic image by the player (observer).

[0041] More specifically, on the rear 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 so as 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 on 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.

[0042] The light source 22 is, for example, an LED (Light Emitting Diode) like the above-mentioned light source 18, and may be a full-color LED capable of changing color. A plurality of light sources may be provided on one end face of the light guide plate 21 in order to uniformly introduce light from the end face. A scattering plate for scattering the light from the light source 22 may be provided, and the light emitted from the light source 22 may be scattered to improve uniformity before being introduced into the light guide plate 21.

[0043] (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.

[0044] The infrared active sensor 23 detects reflected light of the irradiated infrared rays, 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.

[0045] (3. Control device 30 of production 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 composed of 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.

[0046] 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. As a specific example of switching the image displayed on the first display unit 12, a predetermined one or a plurality of predetermined planar light devices 16 among the four planar light devices 16a to 16d are turned on, turned off, or blinked depending on the status of the game being played on the gaming machine 1. The control device 30 may use the detection of the operation on the three-dimensional image 25 by the operation detection unit 15 for a performance device of the gaming machine 1 other than the performance unit 10.

[0047] (4. Operation of the Production Unit 10) Fig. 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 patterns as shown by the reference characters 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).

[0048] 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, the stereoscopic image 25 is made to be a thick push button switch, so that the player is explicitly informed that he or she should press the corresponding part in space. Of course, the stereoscopic image 25 is not limited to this and may be any type.

[0049] 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 in the display area 19.

[0050] 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 of 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 the mirror 14, and are received by the infrared active sensor 23 (the dashed bidirectional arrow in FIG. 6).

[0051] When the reflected infrared light is received by the infrared active sensor 23, the control device 30 determines that an instruction has been input by the player, and switches the image displayed on the first display unit 12, for example.

[0052] (5. Effects) In the performance unit 10 according to the first embodiment, a three-dimensional image of an operation target displayed on the second display unit 13 is visually recognized through the window unit 7 that visually recognizes the performance displayed on the first display unit 12, and the operation of the player with respect to the three-dimensional image is detected by the operation detection unit 15. This allows the player to input instructions in a non-contact manner without touching the gaming machine 1.

[0053] Furthermore, the 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. Furthermore, the operation detection unit 15 can be disposed inside the case 11, allowing it to be made into a unit.

[0054] Here, a comparative example configuration will be described with reference to Fig. 7 in which a cold mirror is not used as the mirror 14, and the infrared active sensor 23 is disposed below (on the back side) the first display unit 12. Fig. 7 is an explanatory diagram showing the optical path of infrared rays in the comparative example configuration.

[0055] 7, when the infrared active sensor 23 is disposed below the first display unit 12, the infrared rays emitted from the infrared active sensor 23 pass through the multiple light guide plates 17a-17d and reach 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 rays pass through the multiple light guide plates 17a-17d in the reverse order to the outward path and return to the infrared active sensor 23.

[0056] Ideally, the optical path of such infrared rays would pass through the parts not provided with the shapes 40, as shown by the dashed lines in the figure. However, the parts of the light guide plates 17a-17d where the shapes 40 are formed differ depending on the respective designs, and it is difficult to arrange the infrared active sensor 23 so that the optical path does not pass through the shapes 40. Therefore, the infrared rays are affected by the shapes 40 and follow the optical path shown by the thick lines in the figure, and the accuracy of detecting operations on the three-dimensional image 25 decreases.

[0057] Moreover, in such a configuration of the 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 back side of the mirror 14, so the infrared active sensor 23 is not visible.

[0058] [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.

[0059] 8 is a schematic diagram showing the configuration of the production unit 10A according to the second embodiment, in which the configuration inside the case 11 is seen from the side of the production unit 10A. As shown in FIG. 8, the production unit 10A differs from the production unit 10 in that the second display unit 13 has two stereoscopic light devices 20.

[0060] Specifically, assuming that 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 the stereoscopic light device 20a, the device further includes a stereoscopic light device 20b that allows the user to view a stereoscopic image 26 of the push button switch in a pressed state. The stereoscopic light device 20a corresponds to the first light device that displays a stereoscopic image of the operation target before operation, and the stereoscopic light device 20b corresponds to the first light device that displays a stereoscopic image of the operation target after operation.

[0061] 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. As a result, the display area 19 displays 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 way 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.

[0062] 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.

[0063] FIG. 9 is a schematic diagram showing the configuration of a production unit 10B according to the third embodiment, with the internal configuration of the case 11 viewed from the side of the production unit 10B. As shown in FIG. 9, in the production unit 10B, the first display section 12 is 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 the liquid crystal display device 51 for the first display section 12, any planar image can be displayed in the display area 19.

[0064] In the case of liquid crystal display device 51, if a normal mirror that reflects infrared light as well as visible light is used as mirror 14, infrared active sensor 23 must be installed on the display surface side of liquid crystal display device 51, which creates the problem of interfering with the display of liquid crystal display device 51. However, as described above, by using a cold mirror as mirror 14 and arranging infrared active sensor 23 on its back side, it is possible to detect operations by infrared active sensor 23 without interfering with the display of liquid crystal display device 51.

[0065] §3 Variations Although the embodiment of the present invention has been described in detail above, 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.

[0066] 1) In the above-described embodiment, an example was shown in which a plurality of planar optical devices (second optical devices) 16 or a liquid crystal display device 51 is 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 adopted in which a display device of a self-luminous device such as an OLED (Organic Light Emitting Diode) is provided.

[0067] 2) If the gaming machine does not have a configuration with reels 2 and space for installing a performance unit can be secured, a hot mirror that reflects infrared rays and transmits visible light may be used instead of a cold mirror as the mirror 14. In that case, the 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.

[0068] 3) In the above-described embodiment, 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 be configured to be provided externally, separately from the performance units 10 to 10B. In that case, various sensors such as a light emitting and receiving sensor can be used, in addition to the infrared active sensor 23.

[0069] 10 is an explanatory diagram showing the main parts of a gaming machine 1D equipped with a rendering device 10D according to a modified example. Although not shown, the rendering device 10D has a first display section 12 and a second display section 13 in a case 11. The difference from the rendering units 10 to 10C described above is that the mirror 14 is a normal mirror that reflects both visible light and infrared light, and that the operation detection section 15 is provided outside the device.

[0070] In the example of Fig. 10, the operation detection unit 15 includes a light projecting and receiving sensor 41. The light projecting and 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, and the light receiving unit 41b receives the projected light. When the light is blocked by an object, the amount of light received by the light receiving unit 41b decreases, and the control device 30 detects the presence of the object in the optical path. The light projecting and receiving sensor 41 is installed so that the space where the stereoscopic image 25 is formed by the second display unit 13 described above, or a space a predetermined range away from the position where the stereoscopic image 25 is formed, is included in the optical path.

[0071] 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.

[0072] [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.

[0073] In the latter case, the control device 30 includes a computer that executes instructions of a program, which is software that realizes each function. The 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 may be, for example, a CPU (Central Processing Unit). The recording medium may be a "non-transient tangible medium," such as a ROM (Read Only Memory), as well as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like. The control device may further include a RAM (Random Access Memory) that expands the program. The program may be supplied to the computer via any transmission medium (such as a communication network or a broadcast wave) that can transmit the program. Note that one aspect of the present invention may also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

[0074] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
