Description

  The present invention relates to a gaming machine including a variable display device capable of displaying a plurality of types of symbols in three dimensions.

  A conventional gaming machine is known that three-dimensionally displays a symbol for variable display (Patent Document 1).

  In addition, as a device for displaying a stereoscopic image using binocular parallax, a character (virtual image) reproduction position (image formation position) is gradually set on the observer side using a display device for the left eye and a display device for the right eye. There is a known display that makes a character jump out by approaching to (Patent Document 2).

In this conventional example, the character is moved from the top of the screen to the bottom, and the amount of popping out of the character is increased as the character is moved downward, so that the top of the image is recognized as a vanishing point and the stereoscopic effect is emphasized. Yes.

  However, in the latter conventional example (Patent Document 2), the character as a three-dimensional image is moved in the vertical direction of the screen, and the parallax of the image is increased so that it jumps out to the player side as the character display position goes downward. Therefore, the character jumps out of the difference between the distance from the real image on the display device to the observer's eyeball (focal distance) and the distance from the virtual image at the stereoscopic image display position to the observer's eyeball (convergence distance). There is a problem that the burden on the observer's eyes increases.

  In particular, since the result of the game is affected by the character moving downward, the observer may have to pay attention to the character, which may further burden the eyes.

  Therefore, an object of the present invention is to provide a gaming machine that can realize a variable display game rich in stereoscopic effect by moving a stereoscopic image while reducing the burden on the eyes of an observer.

According to a first aspect of the present invention, there is provided an image display surface on which a stereoscopic image can be displayed to a player using a left-eye image and a right-eye image having parallax, and a variable display game that displays a plurality of identification information in a variable manner can be displayed. The variable display game, comprising: a display device having game control means for overall control of the game; and display control means for controlling image display of the display device based on a control command from the game control means. In the gaming machine capable of generating a special gaming state advantageous to the player when all of the stop result modes are the same as the special result mode that stops with the same identification information, the image display surface of the display device displays the image display The lower side of the screen is closer to the player side, while the upper side is inclined in the depth direction so as to be away from the player, and the image display surface is inclined to the back side so as to be away from the player side. The upper side of the image display surface is set as the first position, the lower side of the image display surface arranged on the near side so as to be closer to the player side is set as the second position, and the game control means includes: A reach state in which the identification information other than the identification information that stops last in the variable display game stops in the same stop result mode that can form the special result mode, and only the last stopped identification information displays the variable display. When the reach state occurs in the variable display game, the display control means displays one identification information during the change in the reach state as a three-dimensional image, on the image display surface. When displaying a stereoscopic image, change the parallax between the parallax amount setting means for setting the parallax amount between the left-eye image and the right-eye image, and the first position and the second position. Stereoscopic image moving means for moving the stereoscopic image, and the parallax amount setting means, when displaying the stereoscopic image at the first position, maximizes the parallax amount between the left-eye image and the right-eye image. When the stereoscopic image is set to be small and the stereoscopic image is displayed at the second position, the parallax amount between the left-eye image and the right-eye image is set to be the largest, and the stereoscopic image moving means has the reach state In this case, while changing the parallax of one piece of identification information displayed in the stereoscopic image in the reach state, from the first position set above the image display surface to below the image display surface The identification information is moved to a second position to be set, and the identification information is further moved from the second position to the first position.

In a second aspect based on the first aspect, the display control means is moved from the first position to the second position by the stereoscopic image moving means, and further, the second position Identification information switching means for switching the identification information moved from the first position to the next identification information.

According to a third aspect of the present invention, in the first aspect or the second aspect, the display device includes a light source that irradiates light toward the liquid crystal display panel while the image display surface is configured by a liquid crystal display panel. , Optical means for condensing the light emitted from the light source and transmitted through the liquid crystal display panel to a predetermined range, light of a specific polarization out of the light from the light source, and orthogonal to the light of the specific polarization A polarizing unit that transmits polarized light to the optical unit side, a first region that is disposed between the liquid crystal display panel and the optical unit, and transmits the specific polarized light; and the specific unit The second region that transmits the polarized light orthogonal to the polarized light is vertically arranged on the front side of the inclined liquid crystal display panel, and the filter means provided repeatedly in a certain direction. A transparent member.

Therefore, the first invention is arranged such that the image display surface is inclined in the depth direction so that the lower side of the image display surface approaches the player side and the upper side of the image display surface moves away from the player side , and Since the upper side of the image display surface is set as the first position, the lower side of the image display surface is set as the second position, and the stereoscopic image moving means is provided, the stereoscopic image has the first position. When the player moves from the second position or from the second position to the first position, the stereoscopic effect is emphasized, and the player is determined from the focal distance from the player's eyes to the screen and the position where the stereoscopic image is formed. the difference Do can also popping a stereoscopic image to the player side while reducing the convergence distance to the eye Rukoto, reduction of the player's eyes burden and emphasize the stereoscopic effect of the stereoscopic image Can be made compatible.

Further, the second invention includes identification information switching means for switching the symbol of the stereoscopic image moved from the first position to the second position or from the second position to the first position to the symbol of the next stereoscopic image. Thus, the player can visually recognize the stereoscopic image so that the stereoscopic image flows from the upper side to the lower side or from the lower side to the upper side of the image display surface, thereby enhancing the stereoscopic effect.

Further, the third invention allows the left eye image and the right eye image to be visually recognized by the observer's left eye and right eye by the optical means, the polarization means, and the filter means, respectively, and can be viewed with the naked eye without using stereoscopic glasses.

It is possible to prevent the image from being difficult to see due to reflection in the eyes of the person.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a game board of a gaming machine showing an embodiment of the present invention, and FIG. 2 is a block diagram of a control system.

  The gaming board 6 constituting the gaming machine (pachinko gaming machine) includes a variable display device (variable display means) 8, a variable winning device 10 having a big winning port, general winning ports 11 to 15, a starting port 16, and normal symbols. A game area in which the start gates 27A and 27B, the normal symbol display 7, the normal variable winning device 9 (auxiliary winning means), and the like are arranged is formed. Further, a cover glass 18 that covers the front surface of the game board 6 is attached. Further, the periphery of the variable display device 8 provided in the approximate center of the game board 6 is surrounded by the center case 40, and a rolling stage 41 for rolling the game ball 50 is provided below the center case 40. A guiding area 42 for guiding the game ball 50 on the rolling stage 41 toward the start port 16 is formed at the lower central portion of the center case 40.

  The variable display device (display device) 8 displays, for example, three display symbols (identification information) on the left, middle, and right in the display area. For example, numbers “0” to “9” and alphabet letters “A” to “E” are assigned to these display symbols.

  When there is a winning game ball at the start port 16, the variable display device 8 sequentially displays the display symbols composed of the numbers and characters described above. When a winning at the start port 16 is made at a predetermined timing (specifically, when the special symbol random number counter value at the time of winning detection is a winning value), a big hit state (special gaming state) is entered, Stops when the display symbols are aligned (big hit symbol). At this time, the large winning opening of the variable winning apparatus 10 opens wide for a predetermined time (for example, 30 seconds), and a large number of game balls can be acquired.

  The winning of the game ball to the start port 16 is detected by a special symbol start sensor 52 (see FIG. 2). The passing timing of the game ball (specifically, the value of the special symbol random number counter provided in the game control device 100 (see FIG. 2) at the time of winning detection) is used as the special symbol winning memory and the game control device 100. Is stored in a predetermined storage area (special symbol random number storage area) within a predetermined maximum number of times. The number stored in the special symbol winning memory is displayed on the special symbol memory state display 17 including a plurality of LEDs provided on the lower side of the variable display device 8. The game control device 100 plays a variable display game on the variable display device 8 based on the special symbol winning memory.

  The normal symbol display unit 7 starts to display a variation of a normal symbol (for example, a symbol consisting of one number) when a winning game ball is awarded to the normal symbol starting gates 27A and 27B. When winning to the normal symbol start gates 27A and 27B is made at a predetermined timing (specifically, when the normal symbol random number counter value at the time of winning detection is a winning value), it becomes a hit state related to the normal symbol, A normal symbol stops at a winning symbol (hit number). At this time, the normal variation winning device 9 provided in front of the starting port 16 opens wide for a predetermined time (for example, 0.5 seconds), and the winning possibility of the game ball to the starting port 16 is increased.

  The passing of the game ball to the normal symbol start gate is detected by normal symbol start sensors 53A and 53B (see FIG. 2). The passing timing of the game ball (specifically, the value at the time of passage detection of the normal symbol random number counter provided in the game control device 100) is a predetermined memory in the game control device 100 as the normal symbol winning memory. In the area (ordinary symbol random number storage area), a predetermined number of times (for example, a maximum of four consecutive times) is stored as a limit. The stored number of the normal symbol winning memory is displayed on the normal symbol storage state display 19 composed of a plurality of LEDs provided on the left and right of the normal symbol display 7. The game control device 100 performs a winning lottery regarding the normal symbols based on the normal symbol winning memory. The number stored in the normal symbol storage state indicator 19 is set to an arbitrary value.

  FIG. 2 is a block configuration diagram showing a control system centered on the game control device 100.

  The game control device 100 is a main control device that comprehensively controls games, a CPU that controls game control, a ROM that stores invariant information for game control, and a RAM that is used as a work area during game control Is composed of a game microcomputer 101 having a built-in circuit, an input interface 102, an output interface 103, an oscillator 104, and the like.

  The gaming microcomputer 101 receives detection signals from various detection devices (special symbol start sensor 14, general winning opening sensors 17A to 17N, count sensor 15, continuation sensor 16S, normal symbol start sensor 21) via the input interface 102. In response, various processes such as a jackpot lottery are performed. And via the output interface 103, various control devices (display control device 150, discharge control device 200, decoration control device 250, sound control device 300), big prize opening solenoid 36, ordinary electric accessory solenoid 90, normal symbol display. A command signal is transmitted to the device 7 and the like, and the game is comprehensively controlled.

  The discharge control device 200 controls the operation of the payout unit based on a winning ball command signal from the game control device 100 or a lending request from a card ball lending unit (not shown), and discharges a winning ball or a lending ball. To do.

  The decoration control device 250 controls a decoration light emitting device such as a decoration lamp or LED based on a decoration command signal from the game control device 100, and also displays a special symbol memory display (special symbol hold LED) 18, a normal symbol memory. The display of the display 19 is controlled.

  The sound control device 300 controls sound effect output from the speaker. Communication from the game control device 100 to various subordinate control devices (display control device 150, discharge control device 200, decoration control device 250, sound control device 300) is unidirectional from the game control device 100 to the subordinate control device. Only communication is allowed. Thereby, it is possible to prevent an illegal signal from being input to the game control device 100 from the dependent control device side.

  The display control device 150 performs display control of a two-dimensional or three-dimensional image, and includes a CPU (central processing means) 151, a VDC (Video Display Controller or drawing arithmetic means) 156, a ROM 152 that stores programs, a work area, A RAM 153 that stores a frame buffer, an interface 154, a font ROM 158 that stores image data (design data, background image data, moving image object data, texture data, etc.), a DMAC (Direct Memory Access Controller) that controls writing to and reading from the RAM 153, etc. 155, an oscillator 158 for generating a synchronization signal (reference clock), a strobe signal, and the like. The oscillator 158 includes a crystal resonator, an oscillator, and the like.

  The CPU 151 executes a program stored in the ROM 152 and outputs a predetermined variation display game to the variation display device 8 based on a signal from the game control device 100. Two-dimensional image information (symbol display information, background screen) Information, video object screen information, etc.) and 3D image information (symbol display information composed of sprite data, polygon data, etc., background screen information, video object screen information, etc.) The calculation result is stored in a predetermined area of the RAM 153 as a frame buffer.

  The VDC 156 transmits the image information stored in the RAM 153 to the LCD side (synthetic conversion device 170) at a predetermined timing (vertical synchronization signal V # Sync, L / R signal, horizontal synchronization H # Sync).

  The font (character) ROM 157 stores symbols such as identification information used in the variable display game, sprite data such as background and character, polygon data, texture data, and the like.

  The drawing processing performed by the VDC 156 performs two-dimensional and three-dimensional point drawing, line drawing, sprite drawing, triangle drawing, and polygon drawing, and further performs texture mapping, alpha blending, shading processing, hidden surface removal (such as Z buffer processing). Then, the image signal is output to the synthesis conversion device 170 via the γ correction circuit 159.

  Here, the frame buffer sets the frame buffer of the two-dimensional image and the frame buffer of the three-dimensional image respectively in a predetermined storage area of the RAM 153, and the VDC 156 superimposes the two-dimensional image on the two-dimensional image ( (Overlay) output is also possible. Further, in the frame buffer set in the RAM 153, the right-eye image and the left-eye image for displaying a three-dimensional image may be stored in independent frame buffers.

  An oscillator 158 that supplies a clock signal is connected to the VDC 156. The clock signal generated by the oscillator 158 defines the operation cycle of the VDC 156, generates a signal output from the VDC 156, for example, a vertical synchronization signal (V # SYNC) and a horizontal synchronization signal (H # SYNC), and performs composite conversion It is output to the device 170 and the fluctuation display device 8.

  The image signal from the VDC 156 is input to the γ correction circuit 159 and then output to the synthesis conversion device 170. The γ correction circuit 159 corrects the non-linear characteristic of the illuminance with respect to the signal voltage of the variable display device 8 to adjust the display illuminance of the variable display device.

  Further, the CPU 151 of the display control device 150 identifies whether the image data (RGB) to be output to the composite conversion device 170 is a left-eye image or a right-eye image based on the clock signal of the oscillator 158. The L / R signal is output.

  Further, the CPU 151 controls the light emission amount (luminance) of the variable display device 8 based on the state of the variable display (for example, whether it is a normal variable display game or a big hit display) and the state of the game. A control signal DTY # CTR is generated based on the clock signal of the oscillator 158 and output to the fluctuation display device 8.

  Next, the synthesis conversion apparatus 170 is provided with a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer, and writes the right-eye image sent from the VDC 156 to the right-eye frame buffer, and the left-eye image. Is written to the left-eye frame buffer. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, which is written in the stereoscopic frame buffer, and the stereoscopic image data is output to the image display device as an RGB signal.

  The generation of the stereoscopic image by combining the right-eye image and the left-eye image is combined with the right-eye image and the left-eye image at every interval of the half-wave plate 821 attached to the fine phase difference plate 802. . Specifically, since the half-wave plate 821 of the fine retardation plate 802 of the image display apparatus according to the present embodiment is arranged at intervals of the display unit of the liquid crystal display panel 804, the display unit of the liquid crystal display panel 804 is displayed. The stereoscopic image is displayed so that the right-eye image and the left-eye image are alternately displayed for each horizontal line (scanning line).

  The left-eye image data transmitted from the VDC 156 during the output of the L signal is written into the left-eye frame buffer, and the right-eye image data transmitted from the VDC 156 during the output of the R signal is written into the right-eye frame buffer. Then, the left-eye image data written in the left-eye frame buffer and the right-eye image data written in the right-eye frame buffer are read for each scanning line and written into the stereoscopic frame buffer.

  A liquid crystal driver (LCD DRV) 181 and a backlight driver (BL DRV) 182 are provided in the variable display device 8. The liquid crystal driver (LCD DRV) 181 sequentially applies voltages to the electrodes of the liquid crystal display panel based on the V BLANK signal, the V # SYNC signal, the H # SYNC signal, and the RGB signal sent from the synthesis converter 170. A composite image for stereoscopic viewing is displayed on the liquid crystal display panel.

  The backlight driver 182 changes the brightness ratio of the liquid crystal display panel 804 by changing the duty ratio of the voltage applied to the light emitting element (backlight) 810 based on the DTY # CTR signal output from the CPU 151.

  FIG. 3 is an explanatory diagram showing the basic configuration of the optical system of the variable display device 8. The light source 801 includes a light emitting element 810, a polarizing filter (polarizing means) 811, and a Fresnel lens 812 (optical means). The light emitting element 810 includes a point light source such as a white light emitting diode (LED) or a line light source such as a cold cathode tube arranged horizontally. The polarization filter 811 is set so that the light transmitted through the right region 811a and the left region 811b have different polarizations (for example, the light transmitted through the right region 811a and the left region 811b is shifted by 90 degrees).

  The light emitted from the light emitting element 810 is transmitted only through the polarization filter 811 with a certain polarization. That is, of the light emitted from the light emitting element 810, the light that has passed through the left region 811b of the polarizing filter 811 and the light that has passed through the right region 811a are irradiated to the Fresnel lens 812 as differently polarized light. As will be described later, light that has passed through the left region 811b of the polarizing filter 811 reaches the right eye of the viewer, and light that has passed through the right region 811a reaches the left eye of the viewer.

  In addition, even if it does not use a light emitting element and a polarizing filter, what is necessary is just to comprise so that light of a different polarization may be irradiated from a different position, for example, providing two light emitting elements which generate the light of a different polarization, You may comprise so that light may be irradiated to the Fresnel lens 812 from a different position.

  The light transmitted through the polarizing filter 811 is irradiated to the Fresnel lens 812. The Fresnel lens 812 is a convex lens, and the Fresnel lens 812 refracts the optical path of light emitted from the light emitting element 810 so as to be diffused substantially in parallel, passes through the fine retardation plate 802, and irradiates the liquid crystal display panel 804. .

  At this time, the light irradiated through the fine retardation plate 802 is emitted so as not to spread in the vertical direction and is applied to the liquid crystal display panel 804. That is, light transmitted through a specific region of the fine retardation plate 802 is transmitted through a specific display unit portion of the liquid crystal display panel 804.

  Of the light irradiated to the liquid crystal display panel 804, the light that has passed through the right region 811 a of the polarizing filter 811 and the light that has passed through the left region 811 b are incident on the Fresnel lens 812 at different angles. The light is refracted and emitted from the liquid crystal display panel 804 through different paths.

  The liquid crystal display panel 804 has a liquid crystal that is twisted and aligned at a predetermined angle (for example, 90 degrees) between two transparent plates (for example, glass plates). It is composed. The light incident on the liquid crystal display panel is emitted with the polarization of the incident light shifted by 90 degrees in a state where no voltage is applied to the liquid crystal. On the other hand, in a state where a voltage is applied to the liquid crystal, the twist of the liquid crystal can be solved, so that incident light is emitted as it is with polarized light.

  A fine retardation plate 802 and a polarizing plate 803 are disposed on the light source 1 side of the liquid crystal display panel 804, and a polarizing plate 805 is disposed on the player (observer) side.

  In the fine phase difference plate 802, regions for changing the phase of transmitted light are repeatedly arranged at fine intervals. Specifically, the light-transmitting substrate 822 is provided with a region 802a where the half-wave plate 821 having a minute width is provided, and the same interval as the width of the half-wave plate 821 is 1 / The region 802b where the two-wave plate 821 is not provided is repeatedly provided at a fine interval. In other words, the region 802 a that changes the phase of light transmitted by the provided half-wave plate and the region 802 b that does not change the phase of light transmitted because the half-wave plate 821 is not provided are finely spaced. It is provided repeatedly. The half-wave plate 821 functions as a phase difference plate that changes the phase of transmitted light.

  The half-wave plate 821 is disposed so that its optical axis is inclined by 45 degrees with respect to the polarization axis of the light transmitted through the right region 811a of the polarization filter 811, and the polarization axis of the light transmitted through the right region 811a is rotated by 90 degrees. And exit. That is, the polarization of the light transmitted through the right region 811a is rotated by 90 degrees to be equal to the polarization of the light transmitted through the left region 811b.

  The repetition of the polarization characteristics of the fine retardation plate 802 is such that the polarization of light transmitted for each display unit (that is, for each horizontal line in the horizontal direction of the display unit) is set at substantially the same pitch as the display unit of the liquid crystal display panel 804. To be different. Therefore, the polarization characteristics of the fine phase difference plate 802 corresponding to each horizontal line (scanning line) of the display unit of the liquid crystal display panel 804 are different, and the direction of light emitted is different for each horizontal line.

  Alternatively, the repetition of the polarization characteristics of the fine retardation plate 802 is performed by setting the polarization characteristics of the fine retardation plate 802 to a plurality of display units (that is, a plurality of display units) as a pitch that is an integral multiple of the display unit pitch of the liquid crystal display panel 804. It may be set so that the polarization of the light transmitted for each of the plurality of display units differs. In this case, the polarization specification of the fine retardation plate is different for each of the plurality of horizontal lines (scanning lines) of the display unit of the liquid crystal display panel 804, and the direction of the light emitted is different for each of the plurality of horizontal lines. Become.

  Thus, since it is necessary to irradiate the display element (horizontal line) of the liquid crystal display panel 804 with different light every time the polarization characteristic of the fine retardation plate 802 is repeated, the liquid crystal display panel transmits through the fine retardation plate 802. The light irradiated to 804 needs to suppress the vertical diffusion.

That is, the region 802a of the fine phase difference plate 802 that changes the phase of the light is transmitted by changing the light transmitted through the right region 811a of the polarizing filter 811 into light having the same inclination as the polarization of the light transmitted through the left region 811b. . The region 802 b of the fine retardation plate 802 that does not change the phase of light transmits the light that has passed through the left region 811 b of the polarizing filter 811 as it is. The light emitted from the fine retardation plate 802 has the same polarization as the light transmitted through the left region 811b and enters the polarizing plate 803 provided on the light source side of the liquid crystal display panel 804.

The polarizing plate 803 has a polarization characteristic of transmitting light having the same polarization as the light transmitted through the left region 811b of the polarizing filter 811. That is, the light that has passed through the left region 811b of the polarizing filter 811 passes through the region 802b that does not change the phase of the light on the fine retardation plate 802, passes through the polarizing plate 803, and passes through the right region 811a of the polarizing filter 811. The transmitted light is transmitted through the polarizing plate 803 with the polarization axis rotated by 90 degrees when passing through the region 802 a that changes the phase of the light on the fine retardation plate 802. Therefore, by combining the fine retardation plate 802 and the polarizing plate 803, a region that transmits the polarized light that has passed through the left region 811b of the polarizing filter 811 and a region that transmits the polarized light that is shifted by 90 degrees from this polarized light. The filter means provided by repeating in the vertical direction can be configured. In addition, the polarizing plate 805 has a polarization characteristic that transmits light having a polarization different from that of the polarizing plate 803 by 90 degrees.

  The front side (observer side) of the polarizing plate 805 is composed of a lenticular lens in which kamaboko-like irregularities are repeatedly provided in the vertical direction so that light transmitted through the liquid crystal display panel is diffused in the vertical direction. A diffuser (diffusion means) may be provided. Further, instead of the lenticular lens, a mat-like diffusion surface having a higher diffusion finger property in the vertical direction may be provided. By providing such a diffuser, light from a light source whose vertical diffusion is suppressed until it passes through the liquid crystal display panel 804 can be diffused in the vertical direction after passing through the liquid crystal display panel 804. Thus, it is possible to improve the narrowing of the viewing angle.

  FIG. 4 is a front view showing the fine retardation plate 802 of the image display apparatus according to the embodiment of the present invention.

  The fine retardation plate 802 is provided with a half-wave plate, and regions for changing the polarization of transmitted light are repeatedly and continuously arranged at fine intervals at predetermined intervals. The polarization of light incident on this repeatedly arranged region is different in the right region 811a and the left region 811b of the polarization filter 811. In the region where the polarization of transmitted light is changed, the polarization axis of incident light is 90 degrees. Rotate and emit. The repetition of the polarization characteristics of the fine retardation plate 802 is substantially the same pitch as the display unit of the liquid crystal display panel 804.

  That is, the light whose polarization axis is rotated by 90 degrees with the fine phase plate and the left region 811b of the polarization filter 811 are transmitted through the right region 811a of the polarization filter 811 and transmitted through the fine phase plate 802 as it is. The polarization axes of the light are equal, and these lights are transmitted through the second polarizing plate. The region of the fine retardation plate 802 that changes the polarization of the transmitted light and the region that does not change the polarization of the transmitted light are repeatedly and continuously arranged for each horizontal line of the display unit of the liquid crystal display panel 804. The light transmitted through the fine retardation plate 802 and the second polarizing plate 803 becomes the same polarized light that travels in different directions for each horizontal line.

  As described above, the polarization characteristic of the fine retardation plate 802 is repeated as a pitch that is an integral multiple of the display unit pitch of the liquid crystal display panel 804, and the polarization characteristic of the fine retardation plate 802 is set for each of a plurality of display units. It is also possible to change the polarization of transmitted light for each of a plurality of display units.

  FIG. 5 is a cross-sectional view of the variable display device according to the embodiment of the present invention.

  The variation display device 8 is housed in a box-shaped case 800 attached to the back surface of the game board 6 at a position of a through hole 6A provided in the substantially central portion of the game board 6. The case 800 opens on the through hole 6A side, and the periphery of the opening 820 of the case 800 is connected to the center case 40 surrounding the variable display device 8 on the surface side of the game board 6.

  The optical system shown in FIG. 3 is arranged inside the case 800, the light emitting element 810 is arranged at the innermost part of the case 800, and the Fresnel lens 812 is vertically arranged in the middle of the case 800. The polarizing filter 811 is disposed between the light emitting element 810 and the Fresnel lens 812.

  On the other hand, a plate-like transparent member 807 is disposed in the opening 820 of the case 800 in the vertical direction so as to transmit light while preventing dust and the game ball 50 from entering, in other words, parallel to the game board 6. Be placed. The transparent member 807 is formed of a transparent acrylic panel or glass. If the transparent member 807 is disposed obliquely (that is, in parallel with the liquid crystal display panel 804), the illumination from the ceiling of the game hall is reflected as it is to the player side, and it becomes difficult to see the stereoscopic image. A transparent member 807 is arranged vertically to prevent reflection of light from the ceiling.

  Between the Fresnel lens 812 and the transparent member 807, the fine retardation plate 802 and the liquid crystal display panel 804 are disposed in the case 800 in a state where the fine retardation plate 802 and the liquid crystal display panel 804 are inclined in the depth direction at a predetermined angle α. Note that a polarizing plate 803 is provided on the Fresnel lens 812 side of the liquid crystal display panel 804, and a polarizing plate 805 is provided on the transparent member 807 side.

  That is, the fine retardation plate 802 and the liquid crystal display panel 804 are arranged in this order from the Fresnel lens 812 side, and the fine retardation plate 802 and the liquid crystal display panel 804 are close to the Fresnel lens 812 on the upper side, and the Fresnel on the lower side. It is attached at a predetermined angle α by disposing it away from the lens 812, and the focal length from the display surface (image display surface) of the liquid crystal display panel 804 that displays an image to the player's eyes is While it becomes large above the liquid crystal display panel 804, it becomes small below.

  The center case 40 connected to the lower peripheral edge of the variable display device 8 drops the rolling stage 41 for guiding the falling game ball and the gaming ball 50 on the rolling stage 41 to the start port 16 side. A guiding region 42 is formed, and the rolling stage 41 is formed with a bottom portion having a predetermined depth so as not to block light from the liquid crystal display panel 804 to the player in a state where the game ball 50 is rolling. Is done. That is, the rolling stage 41 is formed in a groove shape deeper than the diameter of the gaming ball 50, and the gaming ball rolling on the upper part of the rolling stage 41 is below the opening 820 of the case 800 indicated by the dotted line (ie, The lower end of the image display surface) is located below the extension line 900.

  Further, although the distance from the Fresnel lens 812 to the fine phase difference plate 802 and the polarizing plate 803 is different between the upper side and the lower side, the light from the Fresnel lens 812 to the player is a parallel light. Separation can be ensured and occurrence of crosstalk can be suppressed.

  FIG. 6 is a plan view showing the optical system of the variable display device 8.

  Light emitted from the light emitting element 810 is transmitted through the polarizing filter 811 and spreads radially. Of the light emitted from the light source, the light transmitted through the right region 811a of the polarizing filter 811 reaches the Fresnel lens 812, and the traveling direction of the light is changed by the Fresnel lens 812, so that the fine phase difference plate 802, the liquid crystal display panel 804 and the polarizing plate 805 are transmitted substantially vertically (slightly left to right) and reach the left eye.

  On the other hand, of the light emitted from the light source, the light transmitted through the left region 811b of the polarizing filter 811 reaches the Fresnel lens 812, and the traveling direction of the light is changed by the Fresnel lens 812. It reaches the display panel 804 and the polarizing plate 805, and these are transmitted substantially vertically (slightly from the right side to the left side) to reach the right eye.

  In this way, the light emitted from the light emitting element 810 and transmitted through the polarizing filter 811 is irradiated to the liquid crystal display panel 804 substantially perpendicularly by the Fresnel lens 812 as an optical means, and is emitted by the light emitting element 810, the polarizing filter 811, and the Fresnel lens 812. The light source 1 is configured to irradiate the liquid crystal display panel 804 with light having different polarization planes substantially vertically and through different paths, and the light transmitted through the liquid crystal display panel 804 is emitted through different paths to reach the right eye or the left eye. Let That is, the scanning line pitch of the liquid crystal display panel 804 and the repetition pitch of the polarization characteristics of the fine phase difference plate 2 are made equal, and light coming from different directions is irradiated for each scanning line pitch of the liquid crystal display panel 804 and is different. Light is emitted in the direction.

  FIG. 7 shows a flow chart of the game, and the outline of the game will be described below with reference to this figure.

  First, at the beginning of the game (or before the game is started), the game is waiting for a customer, and a signal instructing display of the customer waiting screen is transmitted from the game control device 100 to the display control device 150, and the variable display device 8 is displayed. A customer waiting screen (moving image or still image) is displayed on the display screen.

  Then, when the game ball launched into the game area wins the start opening 16, a predetermined random number is extracted by the game control device 100 based on the winning, and a lottery drawing of the variable display game is performed, and the game control device A signal for instructing the variable display is transmitted from 100 to the display control device 150, and the variable display of a plurality of symbols is started at a predetermined position in the variable display area set on the display surface of the variable display device 8.

  When a predetermined time elapses after the start of the variable display, the variable display is temporarily stopped in the order of, for example, left, right, and middle (for example, the pattern is slightly changed at the stop position). State (for example, a state where symbols other than the last symbol to stop are stopped in a combination that stops with the same content, and only the last symbol to stop is changing. Specifically, the left symbol and the right symbol are changed. However, since the middle symbols are still changing, the middle symbol is still fluctuating, so that the possibility of reaching a big hit remains.) Occurs, a predetermined reach effect is performed. In this reach effect, for example, the change display of the inside symbol is performed at an extremely low speed, the display is changed at a high speed, or the change display is reversed. In addition, background display and character display are performed in accordance with reach production.

  The temporary stop state is a state in which the player can recognize the symbol as a substantially stopped state, and the final stop mode is not determined. The stopped state includes the temporary stop state and the state in which the symbol is stopped. State. As a specific example of the temporary stop state, in addition to the slight fluctuation at the stop position, there are modes such as displaying the symbol in an enlarged scale, changing the color of the symbol, changing the shape of the symbol, and the like.

  If the result of the jackpot lottery is a jackpot, the left, right, and middle symbols are finally stopped in a predetermined jackpot combination, and a jackpot (jackpot game) is generated. When the jackpot game is generated, a special game is performed in which the variable winning device (big winning opening) 10 is opened for a predetermined period. This special game is executed with a predetermined number (for example, 10) of game balls to be awarded to the variable prize apparatus 10 or a predetermined time (for example, 30 seconds) as one unit (one round). A prescribed round (for example, 16 rounds) is repeated on the condition that a winning is made to the continuous winning opening (detection of a winning ball by the continuous sensor 53). When a jackpot game is generated, a signal for instructing display of the jackpot game is transmitted from the game control device 100 to the display control device 150 such as a jackpot fanfare display, round number display, jackpot effect display, etc. The jackpot game is displayed on the screen.

  In this case, if the jackpot is a specific jackpot, a specific game state is generated after the jackpot game, and the probability of the next jackpot occurrence is set to a high probability (probability variation state), or as described later, to the game ball start port 16. The variation display time of the variation display game of the variation display device 8 based on the winning is reduced.

  When the game ball wins the start opening 16 during the variable display game or the big hit game (when the special symbol start memory or the start memory is generated), after the variable display game is finished (when lost) or a big hit After the game is over, a new variable display game is repeated based on the special symbol start memory. Further, when the variable display game is finished (when lost), or when the big hit game is finished, when there is no special symbol start memory, the waiting state is returned to the customer.

  When the game ball passes through the normal symbol starting gates 27A and 27B, a random number related to the normal symbol is extracted based on the passing or normal symbol starting memory, and if the random number is hit, the normal symbol display 7 performs a hit display. Thus, the normal variation winning device 9 at the start port 16 is expanded for a predetermined time, and winning at the start port 16 is facilitated.

  FIG. 8 is a control flowchart showing an example of the variable display game performed by the display control device 150.

  First, in step S1, a variable display game is started based on the start memory. Here, the case where the identification information (symbol) scrolls in the vertical direction is shown as the variable display. When there is no start memory, a predetermined screen such as a customer waiting screen is displayed to wait for a winning at the start port. One start-up memory is deleted each time the variable display game is started.

  In step S2, the first symbol (left symbol), the second symbol (right symbol), and the third symbol (middle symbol) are determined based on the random number value (the value of the special symbol random number counter) corresponding to the starting memory. If it is a reach and it is determined whether it is a reach, a reach pattern is determined by a preset table or the like.

  Next, in step S3, the parallax between the image for the left eye and the image for the right eye of each symbol is set to “0” in order to set the depth position of each symbol as the display surface (two-dimensional image).

  In step 4, the pattern (identification information) is changed and displayed as a planar image (two-dimensional image). At this time, the third symbol (middle symbol) is displayed at the center of the image display surface (position where diagonal lines passing through the four corners of the liquid crystal display panel 804 intersect), and the first symbol (left symbol) is displayed on the left side of the third symbol. The second symbol (right symbol) is displayed on the right side of the third symbol.

  Next, in step S5, after the fluctuation display is performed for a predetermined time, the first symbol and the second symbol are sequentially stopped by the stop symbol determined in step S2 in step S6.

  In step S7, it is determined whether or not the current variable display game is reach. If the game is reach, the stopped first symbol and second symbol are reduced and displayed in the upper left area of the image display surface ( The first symbol 80L and the second symbol 80R in FIG. 10 are moved to a position above the image display surface to change to a three-dimensional display (at the position of the third symbol 80C in FIGS. 9 and 10). The process proceeds to step S8. If it is not reach in step S7, the process proceeds to step S15.

  In step S15 which is not reach, after stopping the third symbol, the process returns to step S1 to prepare for the next variable display game.

  On the other hand, in step S8 of the reach generation, the variable display is continued while the third symbol (middle symbol) is displayed three-dimensionally. Note that the parallax between the image for the left eye and the image for the right eye of the third symbol, and the position where the image for the left eye and the image for the right eye of the third symbol are pasted on the image display surface are changed in the next step S9.

  In step S9, a process of moving the third symbol stereoscopically displayed at the first position above the image display surface to the second position below the screen and returning it to the first position is performed. At this time, stereoscopic image processing is performed in which the position in the depth direction is changed so as to gradually protrude toward and away from the player (observer). This stereoscopic image processing will be described later.

  In step S10, it is determined whether or not a predetermined time (the time from when a reach occurs until the third symbol stops) has passed and the third symbol has become the stop symbol set in step S2.

  If the 3rd symbol is a predetermined stop symbol, the process proceeds to step S11 to stop the change display of the 3rd symbol. On the other hand, if it is not the stop symbol, the 3rd symbol is switched to the next symbol in step S14 (for example, , The symbol “4” is switched to “5”), and the flow returns to step S8 to continue the variable display of the third symbol.

  After the third symbol becomes a stop symbol and the variable display is stopped in step S11, it is determined in step S12 whether or not the current variable display game is a big hit. Then, a predetermined jackpot display control is performed. After the jackpot display control is completed, the process returns to step S1 to prepare for the next variable display game. If it is not a big hit, the process returns to step S1 to prepare for the next fluctuation display game.

  When the variable display game is reached by the above control, the stereoscopic image processing described later is performed, and the 3D graphic moves up and down and gradually jumps out to the player side as it goes downward. Variation display by image is performed.

  Next, FIG. 9 and FIG. 10 are explanatory diagrams showing an example of the stereoscopic display process performed in step S9, and FIG. 9 is a side view showing a state in which the third symbol is projected to the player side while moving in the vertical direction. FIG. 10 is a front view showing a state in which the third symbol is projected to the player side while moving in the vertical direction.

  First, when reach is reached in step S7, as shown in FIG. 10, the first symbol 80L and the second symbol 80R move to the upper left of the display surface (hereinafter referred to as a screen) of the liquid crystal display panel 804. In the meantime, the third symbol 80C is reduced to a stop state, while the third symbol 80C has a predetermined pop-out amount (parallax: specific) at a predetermined position (starting point or first position) above the screen as shown in FIG. Specifically, the difference between the left-eye image and the right-eye image output on the liquid crystal display panel 804 is displayed in a three-dimensional manner. The pop-out amount at this time is set to the smallest pop-out amount L1 as shown in FIG. 9, and the first pop-out amount from the image display surface (liquid crystal display panel 804) inclined in the depth direction at a predetermined angle α toward the player side. 3 The pattern 80C jumps out with the smallest popping amount.

  The third symbol 80C gradually increases the pop-out amount while moving downward on the screen, and the pop-out amount is set to L2 at the lowest position 80C '(end point, second position). The pop-out amount L2 at the lowermost position 80C 'is set larger than the pop-out amount L1 at the uppermost position 80C at the start of the variable display.

  The third symbol that has reached the lowermost position 80C 'gradually reduces the pop-out amount while moving upward toward the uppermost position 80C. When the third symbol reaches the uppermost position 80C, it switches to the next symbol in step S14. When step S9 is executed again, it moves again to the lower position 80C ′ and then reciprocates to the uppermost position 80C. As described above, the variable display for changing the pop-out amount according to the vertical position is repeated. This three-dimensional variation display is performed until a stop symbol is obtained in step S10 of FIG.

Here, in the case where the image display surface is arranged in the vertical direction as in the conventional example, an attempt to display the third symbol more realistically at the lower position 80C ′ where the pop-out amount is the largest is shown in FIG. As shown, it is necessary to set L2 ′, which is the maximum pop-out amount, that is , the parallax between the left eye image and the right eye image of the third symbol. On the other hand, when the lower side of the image display surface is close to the player side (front side) as in the present invention, while the upper side is inclined so as to be away from the player, the pop-out amount is larger than that of the conventional example. The
L2'-L2
Can only be reduced.

  Thereby, while reducing the difference between the focal distance from the player's eye i to the screen and the convergence distance from the position where the third figure (stereoscopic image) is imaged to the player's eye i, to the same position. It is possible to jump out, and it is possible to achieve both the reduction of the burden on the player's eyes i and the emphasis on the stereoscopic effect of the variable display game.

  In addition, since the starting point of the variable display in which the third pattern is displayed in three dimensions is located above the center of the screen, the player can be recognized as the vanishing point of the screen, and the stereoscopic effect can be emphasized more. is there.

  In the above description, the 3rd symbol 80C is reciprocated between the starting point at the upper part of the screen and the ending point at the lower part of the screen. However, the starting point may be the lower part of the screen.

  Although the pop-out amount at the starting point at the top of the screen is L1, the pop-out amount may be 0, in other words, a two-dimensional image.

  FIGS. 11 and 12 show the second embodiment, in which the three-dimensional display of the third symbol is overlaid in place of the variable display by the vertical reciprocation shown in FIGS. 9 and 10 of the first embodiment. The other configuration is the same as that of the first embodiment except that the next symbol appears in step S9 instead of updating the symbol in step S14.

  In this embodiment, as shown in FIG. 12, when reach is achieved in step S7, the first symbol 80L and the second symbol 80R are displayed on the display surface of the liquid crystal display panel 804 (as shown by T1 in the figure). While moving to the upper left of the screen), it is reduced and stopped, while the third symbol 80a is displayed at the upper right of the screen with the minimum pop-out amount La (see FIG. 11), and the variable display of only the third symbol is started. Is done.

  Then, when step S9 is first executed, after a predetermined time after the first third symbol 80a is displayed three-dimensionally, the second third symbol 80b is It is displayed in a three-dimensional manner with a pop-out amount Lb so as to overlap below the third third pattern 80a (diagonally lower left). The pop-out amount Lb at this time is set larger than the first pop-out amount La. Then, the process proceeds to step S10, and if it is not a stop symbol, the process proceeds to step S8 (in this embodiment, step S14 is not executed). If it is a stop symbol, the process proceeds to step S11, and the result of the variable display game is displayed. .

  Then, when step S9 is executed next, after a predetermined time since the second third symbol 80b is displayed three-dimensionally, the third third symbol 80c as shown by T3 in FIG. It is displayed in a three-dimensional manner with a pop-out amount Lc so as to overlap below the second third symbol 80b (diagonally lower left). At this time, the pop-out amount Lc is set larger than the second pop-out amount Lb. Then, the process proceeds to step S10, and if it is not a stop symbol, the process proceeds to step S8 (in this embodiment, step S14 is not executed). If it is a stop symbol, the process proceeds to step S11, and the result of the variable display game is displayed. .

  Then, when step S9 is executed next, the fourth (last) third symbol is displayed as indicated by T4 in FIG. 12 after a predetermined time has elapsed since the third third symbol 80c is displayed three-dimensionally. 80d is displayed three-dimensionally with a pop-out amount Ld so as to overlap below the third third pattern 80c (diagonally lower left). At this time, the pop-out amount Ld is set larger than the third pop-out amount Lc. Then, the process proceeds to step S10, and if it is not a stop symbol, the process proceeds to step S8 (in this embodiment, step S14 is not executed). If it is a stop symbol, the process proceeds to step S11, and the result of the variable display game is displayed. .

  Thus, the variation display of the third symbol is such that after the first third symbol 80a is three-dimensionally displayed with the smallest pop-out amount La, a new symbol overlaps at a lower position every predetermined time, and the pop-out amount Is displayed so as to increase gradually.

  Therefore, in this case as well, in the same manner as in the first embodiment, by repeating the 3rd pattern in which the pop-out amount sequentially increases from the tilted screen, each time the pattern is switched toward the result of the variable display game, step by step. In addition, the amount of popping out to the player side can be increased to perform a variable display game rich in three-dimensionality. Further, as in the first embodiment, compared to the conventional example in which the screen is arranged in the vertical direction. Thus, by reducing the amount of protrusion from the screen, the convergence angle of the player's eye i can be reduced, and the burden on the player's eye i can be reduced.

  Further, since the previously displayed stereoscopic image remains, a new stereoscopic image is superimposed and displayed (for example, the symbols “4” and “5” are not erased but overlapped with this). Since the symbol “6” is newly displayed at the position 80c), when the line of sight is shifted from the previously displayed stereoscopic image to the newly displayed stereoscopic image, the convergence angle and the convergence distance change. However, since the degree of the change is small, the stereoscopic image can be easily recognized.

  In each of the above embodiments, the case where the pop-out amount of the third symbol is changed has been described. However, the present invention is not limited to this, and any three-dimensional image object such as a symbol or character to be displayed in three dimensions. Good.

  Moreover, in the said embodiment, you may change the size of a symbol according to a display position, for example, a symbol is expanded as it protrudes to the player side, and it shrinks as it distances to the display surface side of the variable display apparatus 8. It may be.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  As described above, in the gaming machine according to the present invention, when the symbols are moved three-dimensionally in the depth direction of the screen, the amount of change in the convergence angle per player unit time is constant. For game machines such as pachinko machines (ball ball game machines) and pachislot machines (slot machine game machines) that reduce the burden on the eyes of the player while improving the interest by performing effects such as variable display games with typical designs Can be applied.
