Description

  The present invention relates to a gaming machine including a display device capable of three-dimensionally variably displaying a plurality of types of symbols.

  As a conventional gaming machine, as disclosed in Japanese Patent Laid-Open No. 9-103558 and the like, there is known a game machine equipped with a variable display device that three-dimensionally displays symbols when reach or the like occurs.

In this type of variable display device, as disclosed in Japanese Patent Laid-Open No. 7-31729, the left-eye image and the right-eye image are displayed on the image display unit and displayed using a lenticular lens. The image is divided into the left and right eyes of the player independently, so that a stereoscopic view is possible.
JP-A-9-103558 Japanese Patent Laid-Open No. 7-31729

  However, in the latter conventional example (Japanese Patent Laid-Open No. 7-31729), the transmitted light that has passed through the lenticular lens is divided into a right eye image and a left eye image, so that the light reaches the player's eyes from the light source. Since the amount of light is about half that of normal two-dimensional display (2D display), the screen of the variable display device appears dark.

  Furthermore, since the viewing angle and the imaging range are extremely narrow in the three-dimensional image display, the observer's viewpoint such as a player is at a predetermined imaging position (or within the range) of the left-eye image and the right-eye image. A three-dimensional three-dimensional image (virtual image) can be observed, but as the distance from the imaging position, the three-dimensional image gradually disappears and becomes a two-dimensional image, and when further away, the screen becomes dark due to insufficient light quantity. There was also a problem.

  For this reason, when a player selects a gaming machine and looks at the variation display device of the gaming machine while walking along the aisle, even if the waiting screen (or demo screen) is displayed on the variation display device, the screen However, since it is dark, the player cannot easily see it, and there is a problem that the appeal power to attract the player is reduced.

  Therefore, the present invention has been made in view of the above problems, and improves the visibility of the customer waiting screen of the variable display device capable of displaying a three-dimensional image, increasing the appeal to the player, An object is to enable an observer other than a player such as an employee to easily check an image.

  1st invention has the image area for left eyes and the image area for right eyes in a display area, the liquid crystal panel which can permeate | transmit the light irradiated from back, arrange | positioned behind the said liquid crystal panel, and this liquid crystal panel A backlight that irradiates light, a first region that is disposed between the liquid crystal panel and the backlight and transmits light of a specific polarization from the backlight, and a polarization that is orthogonal to the light of the specific polarization A polarizing filter having a second region for transmitting light; and a liquid crystal panel disposed between the liquid crystal panel and the polarizing filter, refracting light of different polarizations transmitted through the polarizing filter to irradiate the liquid crystal panel, and A display device comprising: optical means for allowing a player to view a stereoscopic image by causing light transmitted through the image area for the eye and the image area for the right eye to be incident independently on the left eye and the right eye of the player; Predetermined Based on the establishment of the start condition, the variable display control means for performing a variable display game by variably displaying a plurality of types of identification information as a stereoscopic image in the display area of the display device, and the variable display game derives a specific result mode And a special gaming state control means for generating a special gaming state that can give a bonus to a player in the case where the diffused light that is disposed behind the backlight and does not pass through the polarizing filter is provided. An auxiliary light source that irradiates the entire liquid crystal panel and transmits light that passes through the left-eye image area and the right-eye image area to both eyes of the player, and the gaming state becomes a waiting state for a non-gamed customer Specific state determining means for determining whether or not the specific state determining means is in a customer waiting state, and a demo image preset in correspondence with the customer waiting state As a demonstration image display control means for displaying in the display area, the auxiliary light source is turned on in response to the demonstration image being displayed in the display area, and the identification information is variably displayed in the display area. Correspondingly, the auxiliary light source control means for turning off the auxiliary light source, and when the display of the identification information is switched to the display of the demo image, the auxiliary light source control means When the display of the demonstration image is switched to the display of the identification information while the light source is turned on, the auxiliary light source is turned off before the display is switched.

  According to a second aspect of the present invention, in the first aspect, the auxiliary light source control unit drives the auxiliary light source to blink when a predetermined time has elapsed after the demonstration image is displayed. .

  Further, a third invention includes a backlight control means for performing control to change the luminance of the backlight in the second invention, and the backlight control means is provided when the auxiliary light source is turned on. Reduces the luminance of the backlight.

  Therefore, according to the first aspect of the present invention, in the variable display during the game, the liquid crystal panel is irradiated with the light from the backlight (main light source) to display the stereoscopic image, while the game state becomes the waiting state for the customer. The auxiliary light source is turned on and the liquid crystal panel is irradiated to display a planar image.

  For this reason, the brightness of the screen of the display device (the amount of light transmitted through the liquid crystal panel) greatly increases in the waiting state for the customer, and the viewing angle of the display device increases due to the light from the auxiliary light source. Employees can easily check the screen from the side of the gaming machine and solve the problem that the screen of the gaming machine displaying a stereoscopic image is difficult to see from a viewpoint other than the player as in the previous example. It is possible to improve the visibility of players and employees in the waiting state.

  In addition, since the auxiliary light source is turned on after the display of the identification information as the stereoscopic image is switched to the display of the demo image as the planar image, the stereoscopic image cannot reach both eyes of the player by the light from the auxiliary light source. Thus, occurrence of crosstalk can be prevented. In addition, since the auxiliary light source is turned off before the display of the demo image as the planar image is switched to the display of the identification information as the stereoscopic image, it is possible to prevent the occurrence of crosstalk in the left and right images.

  According to the second aspect of the present invention, the auxiliary light source can be driven to blink, thereby saving power and suppressing heat generation of the auxiliary light source to promote heat dissipation of the display device.

  Further, the invention according to claim 3 can suppress the amount of heat generated by the entire light source and reduce the increase in power consumption by reducing the luminance of the backlight when the auxiliary light source is turned on.

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

  The variable display device 8 displays three display symbols (identification information), for example, 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 (special symbols) composed of the above-described numbers and characters. 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), it is a big hit state and three display symbols are arranged. Stop in state (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 51 (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 gates 27A and 27B is detected by the normal symbol start sensor 52 (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.

  The front frame 3 on the upper part of the cover glass 18 is provided with a first notification lamp 31 and a second notification lamp 32 (see FIG. 2) for reporting a state such as abnormal discharge of a sphere by lighting.

  The operation panel 26 for the card ball lending unit includes a card balance display unit (not shown) for displaying the card balance, a ball lending switch 28 for instructing ball lending, a card return switch 30 for instructing to return the card, and the like. Is provided.

  The card ball lending unit 2 incorporates a card reader / writer and a ball lending control device for reading and writing data of a card (a prepaid card or the like) inserted into the card insertion unit 25 on the front surface. The operation panel 26 is formed on the outer surface of the upper plate 21 of the gaming machine 1.

  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 51, general winning opening sensors 55A to 55N, count sensor 54, continuation sensor 53, normal symbol start sensor 52) 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 prize ball command signal from the game control device 100 or a ball rental request from the card ball rental unit 2, and causes the prize ball or the ball to be discharged.

  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 constituting the display control means performs image display control, and functions as a display control means together with the composite conversion device 170. The display control device 150 stores a CPU 151, a VDC (Video Display Controller) 156, a RAM 153, an interface 155, a ROM 152 storing programs, image data (design data, background image data, moving image character data, texture data, etc.). The font ROM 157 includes an oscillator 158 that generates a timing signal and the like for generating a synchronization signal and a strobe signal.

  The CPU 151 executes a program stored in the ROM 152, and based on a signal from the game control device 100, image control information for a predetermined variable display game (symbol display information including sprite data, polygon data, etc., background screen) Information, moving image object screen information, etc.) to instruct the VDC 156 to generate an image.

  The VDC 156 performs, for example, polygon drawing (or normal bitmap drawing) of an image based on the image data stored in the font ROM 157 and the content calculated by the CPU 151, and a predetermined texture for each polygon. Is pasted and stored in the RAM 153 as a frame buffer. Then, the VDC 156 transmits the image in the RAM 153 to the LCD side (the composite conversion device 170) at a predetermined timing (vertical synchronization signal V_SYNC, horizontal synchronization signal H_SYNC).

  The drawing processing performed by the VDC 156 performs point drawing, line drawing, triangle drawing, polygon drawing, and further performs texture mapping, alpha blending, shading processing (glow shading, etc.), hidden surface removal (Z buffer processing, etc.), and γ correction. The image signal is output to the composition conversion device 170 via the circuit 159.

  Note that the VDC 156 may temporarily store the drawn image data in the RAM 153 as a frame buffer, and then output the image data to the synthesizing / conversion device 170 in accordance with a synchronization signal (V_SYNC or the like).

  Here, as the frame buffer, a plurality of frame buffers are respectively set in a predetermined storage area of the RAM 153, and the VDC 156 can also superimpose (overlay) an arbitrary image and output it.

  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. The VDC 156 divides this clock signal to generate a vertical synchronization signal (V_SYNC) and a horizontal synchronization signal (H_SYNC), and outputs them to the synthesis converter 170. At the same time, the VDC 156 outputs a vertical synchronization signal (V_SYNC) and a horizontal synchronization signal (H_SYNC) to the fluctuation display device 8 via the synthesis conversion device 170.

  The RGB signal output from the VDC 156 is input to the γ correction circuit 159. The γ correction circuit 159 corrects the non-linear characteristic of the illuminance with respect to the signal voltage of the variation display device 8, adjusts the display illuminance of the variation display device 8, and generates an RGB signal to be output to the variation display device 8. .

  Further, the CPU 151 of the display control device 150 determines 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. An identifying L / R signal is output.

  Furthermore, the CPU 151 determines whether the variable display device 8 is based on the state of the variable display (for example, whether it is a normal variable display game or a big hit display) or the state of the game (for example, whether the customer is waiting). In order to control the light emission amount (luminance), a duty control signal DTY_CTR is generated based on the clock signal of the oscillator 158 and output to the variable display device 8.

  The synthesizing / conversion device 170 includes 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. The image for writing is written into the frame buffer for the left eye. 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 variable display device 8 as an RGB signal.

  As shown in FIG. 3, the generation of the stereoscopic image (stereoscopic image) by combining the right eye image and the left eye image is performed by the half-wave plate 821 attached to the fine retardation plate 802. At each interval, the right eye image and the left eye image are combined. Specifically, since the half-wave plate 821 of the fine retardation plate 802 of the variable display device 8 of the present embodiment is arranged at intervals of the display unit of the liquid crystal display panel 804, the display of the liquid crystal display panel 804 is performed. The stereoscopic image is displayed so that the right-eye image and the left-eye image are alternately displayed for each unit 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.

  In the variable display device 8, a liquid crystal driver (LCD DRV) 181, a backlight driver (BL DRV) 182, and a lamp driver 183 are provided. A liquid crystal driver (LCD DRV) 181 sequentially applies voltages to the electrodes of the liquid crystal display panel based on the V_SYNC signal, the H_SYNC signal, and the RGB signal sent from the synthesis converter 170, and applies a stereoscopic image to the liquid crystal display panel 804. The composite image of is displayed.

  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.

  The lamp driver 183 controls turning on and off of the auxiliary light source 814 in accordance with a control signal (LMP_CTR) from the CPU 151.

  In addition, a launch control device 550 that controls a launch device (not shown) based on an operation amount of the operation unit 24 is provided, and the launch control device 550 sends a display state of a game ball to the display control device 150. (Signal indicating presence / absence of firing) is input.

  The oscillator 158 is backed up by a battery (not shown) or the like and has a clock function for counting time based on a reference signal.

  FIG. 3 is an explanatory diagram showing the configuration of the variable display device 8, and the light source 801 (main light source) includes a light emitting element 810, a polarizing filter 811, and a Fresnel lens 812. The light emitting element 810 is configured by using a point light source such as a white light emitting diode (LED) side by side or a line light source such as a cold cathode tube arranged horizontally. The polarizing filter 811 is set so that the light transmitted through the left region 811a and the right region 811b has different polarization (for example, the light transmitted through the left region 811a and the right region 811b is shifted by 90 degrees). The Fresnel lens 812 has a lens surface having concentric irregularities on one side.

  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 observer, 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 (second polarizing plate) are arranged on the light source 1 side of the liquid crystal display panel 804, and a polarizing plate 805 (first polarizing plate) is arranged on the viewer side. ing.

  In the fine phase difference plate 802, regions for changing the phase of transmitted light are repeatedly arranged at fine intervals. Specifically, a region 802a in which a half-wave plate 821 having a fine width is provided on a light-transmitting substrate and a half interval equal to the width of the half-wave plate 821 are ½. The region 802b where the 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. That is, the region 802b where the half-wave plate 821 is not provided transmits light having the same polarization as the polarizing plate 803, which has passed through the left region 811b. In the region 2 a where the half-wave plate 821 is provided, the light having the polarization axis orthogonal to the polarizing plate 803 that has passed through the right region 11 a is rotated so as to be equal to the polarizing axis of the polarizing plate 803 and is emitted. .

  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 functions as a second polarizing plate and 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 transmitted through the left region 811b of the polarizing filter 811 is transmitted through the second polarizing plate 803, and the light transmitted through the right region 811a of the polarizing filter 811 is rotated through the polarization axis by 90 degrees to pass through the second polarizing plate 803. To Penetrate. In addition, the polarizing plate 805 functions as a first polarizing plate and has a polarization characteristic of transmitting light having a polarization different from that of the polarizing plate 803 by 90 degrees.

  Such a fine retardation plate 802, a polarizing plate 803, and a polarizing plate 805 are attached to a liquid crystal display panel 804, and the fine retardation plate 802, a polarizing plate 803, a liquid crystal display panel 804, and a polarizing plate 805 are combined to form an image display device. Configure. At this time, in a state where a voltage is applied to the liquid crystal, light transmitted through the polarizing plate 803 is transmitted through the polarizing plate 805. On the other hand, in a state where no voltage is applied to the liquid crystal, the light transmitted through the polarizing plate 803 is not transmitted through the polarizing plate 805 because the polarized light is twisted 90 degrees and emitted from the liquid crystal display panel 804.

  The diffuser 806 is attached to the front side (observer side) of the first polarizing plate 805 and functions as a diffusing unit that diffuses light transmitted through the liquid crystal display panel in the vertical direction. Specifically, light transmitted through the liquid crystal display panel is diffused up and down using a lenticular lens in which kamaboko-shaped irregularities are repeatedly provided in the vertical direction.

  In place of the lenticular lens, a mat-like diffusion surface having a stronger diffusion finger property in the vertical direction may be provided. It is possible to improve that the viewing angle is narrowed by suppressing the vertical diffusion until the liquid crystal display panel 804 is transmitted.

  Further, an auxiliary light source 814 is disposed in the back of the light emitting element 810 serving as a main light source. The auxiliary light source 814 is composed of, for example, a plurality of light bulbs or a plurality of light emitting elements (LEDs or ELs) and the like that is brighter (higher brightness) than the light emitting element 810. A customer or an amusement shop employee can view a demonstration screen or a pattern from a distance or from a position other than a predetermined imaging position. By increasing the amount of light transmitted through the liquid crystal display panel 804, the field of view of the screen of the variable display device 8 is displayed. Enlarge the corners. Therefore, the light from the auxiliary light source 814 does not need to pass through the polarizing filter 811, passes through the liquid crystal display panel 804 from the Fresnel lens 812, the fine retardation plate 802 and the polarizing plate 803, and passes through the polarizing plate 805 and the diffuser 806. After that, it reaches players and amusement store employees.

  Since most of the light from the auxiliary light source 814 is diffused light that has not passed through the polarizing filter 811, it is irradiated on the entire liquid crystal display panel 804 to improve the brightness of the screen of the display device 8, and a two-dimensional image ( The viewing angle of the (planar image) can be enlarged.

  FIG. 4 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 that has passed through the right region 811a of the polarizing filter 811 (the center of the optical path is indicated by the alternate long and short dash line) reaches the Fresnel lens 812, and the Fresnel lens 812 diffuses the diffusion light source in the vertical direction. While suppressing, it emits as substantially parallel light. Then, the light passes through the fine retardation plate 802, the polarizing plate 803, the liquid crystal display panel 804, and the polarizing plate 805 to 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 (the center of the optical path is indicated by a broken line) reaches the Fresnel lens 812, and diffuses in the vertical direction of the diffusion light source by the Fresnel lens 812. And is emitted as substantially parallel light. Then, the light passes through the fine retardation plate 802, the polarizing plate 803, the liquid crystal display panel 804, and the polarizing plate 805 to reach the right eye.

  In this manner, 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 by the Fresnel lens 812 as an optical means. That is, the light emitting element 810, the polarizing filter 811, and the Fresnel lens 812 constitute a light source 801 that irradiates the liquid crystal display panel 804 with light having different polarizations through different paths, and radiates light that has passed through the liquid crystal display panel 804 through different paths. To reach the right eye or the left eye. That is, the scanning line pitch of the liquid crystal display panel 804 and the repetition pitch of the polarization characteristics of the fine retardation plate 802 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.

  On the other hand, most of the light from the auxiliary light source 814 does not pass through the polarizing filter 811 and remains as diffused light through the Fresnel lens 812, the fine retardation plate 802, the polarizing plate 803, the liquid crystal display panel 804, the polarizing plate 805, and the diffuser 806. Go through to the player side. Therefore, unlike the light that has passed through the polarizing filter 811 described above, the light from the auxiliary light source 814 displays a two-dimensional image without forming a three-dimensional image.

  Next, an example of light emission control according to the gaming state performed by the display control device 150 will be described with reference to FIGS.

  FIG. 5 is a state transition diagram of the game, and FIGS. 6 and 7 are flowcharts of the light emission control performed by the display control device 150.

  FIG. 5 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 customer waiting state (specific state) is entered, and a signal instructing display of the customer waiting screen is transmitted from the game control device 100 to the display control device 150, On the screen of the variable display device 4, a customer waiting screen (model name of the gaming machine, a demonstration moving image or a still image using an appearing character) is displayed, and the player is prompted to play a game.

  Then, when a game ball launched into the game area of the game board 6 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. Then, the game control device 100 transmits a signal for instructing the display control device 150 to display the variable display, and the variable display of the plurality of symbols is started in the left, right, and middle variable display areas of the screen 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). When a state (for example, a combination in which the left symbol and the right symbol may generate a jackpot combination) occurs, a predetermined reach game is performed. In this reach game, for example, the variation display of the inside symbol is performed at a very low speed, the variation is performed at a high speed, or the variation display is reversed. In addition, background display and character display in accordance with the reach game are performed.

  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 symbols on the left, right, and center are finally stopped in a predetermined jackpot combination, and a jackpot game (a special game state advantageous to the player) is generated. When this jackpot game is generated, a special game is performed in which the variable winning device 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 high probability state (probability fluctuation state) occurs after the jackpot game, and the probability of the next jackpot occurrence is made high, or based on winning the game ball at the start port 16 The variation display time of the variation display game of the variation display device 8 is shortened.

  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 is generated), the big hit game ends after the variable display game ends (when it is lost) or After that, a new variation 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 start gates 27A and B, a random number related to the normal symbol is extracted based on the passing or normal symbol start memory, and if the random number is correct, the normal symbol display 7 displays a hit. 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. 6 is a flowchart of light emission control performed by the CPU 151 of the display control device 150, and is executed at predetermined time intervals (for example, every several tens or several hundreds of milliseconds).

  First, in step S1, it is determined whether or not it is display control of a big hit screen. That is, it is determined whether the display command signal received from the game control device 100 corresponds to the occurrence of jackpot or the end of jackpot, and if it falls into either one, the process proceeds to step S11, but does not fall into either The process proceeds to step S2. In step S11, display control of a jackpot (giving specific game value) screen as described later is performed.

  In step S2, which is not a big hit, it is determined whether or not the current gaming state is in a probability variation state. If it is not in the probability variation state, the process proceeds to step S3. Take control.

  In step S3, it is determined whether or not a variable display game or the like is being executed. If the game is not being executed (that is, the special symbol is not variably displayed and the special symbol start memory number is 0). If there is any), the process proceeds to step S4, while if the game is being executed, the process proceeds to step S9 to perform normal display control.

  In step S4, it is determined whether or not the game ball is in a firing state based on a signal from the launch control device 550. If it is not in the firing state, the process proceeds to step S5. If it is in the firing state, the process proceeds to step S9. Display control.

  Next, it is determined whether or not the customer waiting flag is 1. If the customer waiting flag is not 1, the process proceeds to step S6 to prepare for the transition to the customer waiting state, while the customer waiting flag is 1 and the customer waiting state. If so, the process proceeds to step S10 to perform display control for waiting for the customer as will be described later.

  In step S6 for preparing for transition to the customer waiting state, the transition timer TM is incremented by a predetermined value (for example, 1), and in step S7, whether the value of the timer TM has exceeded a predetermined value (customer waiting determination value). Determine whether or not. This customer waiting determination value is set to a value corresponding to a preset time, for example, the value of the timer TM corresponding to several minutes, etc., for estimating the time after the player leaves the gaming machine. Is.

  If the value of the timer TM is less than or equal to the predetermined value, the process proceeds to step S9 to perform normal display control. On the other hand, if the value of the timer TM exceeds the predetermined value, it is determined that there is no player and the process proceeds to step S8. While setting the waiting flag to 1, the timer TM is reset, and further, the current time (start time of the customer waiting display) is stored, and the state shifts to the customer waiting state. In other words, from the next control cycle, the process proceeds to the display control in the customer waiting state in step S10 by the determination in step S5.

  In this way, when a predetermined time (customer waiting determination value) elapses after the game ball is stopped, the game is shifted to a customer waiting state except when the game is running, such as a variation display game.

  In step S3, both the execution state of the variation display game and the launch state of the game ball are determined. However, the monitoring of the launch state of the game ball performed in step S4 is omitted, and only the execution of the variation display game is performed. You may make it monitor.

  Conversely, the determination of the presence or absence of the variable display game performed in step S3 may be omitted, and the determination of the waiting state for the customer may be performed only by monitoring the game ball firing state in step S4.

  Next, FIG. 7 shows a display control subroutine in the customer waiting state performed in step S10 of FIG.

  In step S12, which is determined to be a customer waiting state, preset sequence data or the like is read and a predetermined customer waiting screen (demo screen) is displayed.

  Next, in step S13, the current time is read from the clock of the oscillator 158, and in step S14, the read time is a predetermined time set in advance (for example, a predetermined time has elapsed from the start time of the customer waiting display stored in step S8). If the predetermined time has not been reached, the process proceeds to step S15 to command the auxiliary light source 814 to be turned on and the process is terminated. If the predetermined time has elapsed, the process proceeds to step S16. The auxiliary light source 814 is extinguished.

  With the above control, display of game effects is not performed, and when a predetermined time elapses after the game ball is no longer fired, a transition is made to a customer waiting state, and a predetermined demo screen is displayed based on the flowchart of FIG. In addition to the display, the bright auxiliary light source 814 is turned on in addition to the light emitting element 810 as the main light source. Then, when a certain time (for example, 10 minutes) elapses from the display of the demonstration screen, the auxiliary light source 814 is turned off and heat generation by the auxiliary light source 814 is suppressed.

  In addition, instead of turning off the auxiliary light source 814 when a certain time has elapsed since the display of the demonstration screen, control may be performed such that the auxiliary light source 814 is dimmed. Alternatively, control may be performed in which the auxiliary light source 814 is driven to blink to suppress heat generation when a certain time has elapsed since the display of the demonstration screen.

  In this way, lighting of the auxiliary light source 814 significantly increases the screen brightness of the variable display device 8 (the amount of light transmitted through the liquid crystal panel), and fluctuates due to diffused light that does not pass through the polarizing filter 811 from the auxiliary light source 814. The viewing angle of the display device 8 is increased, and the player in the aisle can easily check the demonstration screen from a distance such as the side of the gaming machine, and displays a stereoscopic image as in the conventional example. It is possible to solve the problem that the screen of the gaming machine is difficult to see from a viewpoint other than the player, and to improve appeal to the player in the waiting state.

  Furthermore, the light and darkness of the variable display device makes it easy to know whether the customer is waiting or whether the player has temporarily left the seat while playing a game, and can easily determine whether there is a vacant seat. . In particular, since the transition to the waiting state for the customer is not performed in the probability variation state, even if the player temporarily leaves the seat with a meal or the like in the probability variation state, the transition to the waiting state for the customer is prohibited. Even if the player leaves the gaming machine, it does not seem to be vacant for other players, and troubles between the players can be suppressed.

  Note that the timing for turning off, dimming, and blinking the auxiliary light source 814 is not only when a certain time has elapsed since the display of the demo screen as described above, but also at a preset closing time of a game store (or immediately before the closing time). The auxiliary light source 814 can be turned off, dimmed, or blinked in accordance with the above. In this way, the auxiliary light source 814 is automatically turned off, dimmed, and blinks when the store closes in the waiting state for customers, thus saving power and dissipating heat from the fluctuation display device 8 due to heat generated by the auxiliary light source 814. It is possible to promote maintenance and make maintenance easier after closing.

  FIG. 8 shows a normal display control subroutine performed in step S9 of FIG.

  When the normal display is determined in steps S2 to S4 or S7 in FIG. 6 above, in step S21, the customer waiting flag is reset to 0 and the timer TM is set to 0, and then the auxiliary light source 814 is turned off in step S22. Then, the liquid crystal display panel 804 is irradiated only with the main light source 801.

  In step S23, display control of a variable display game or the like according to a command from the game control apparatus 100 such as variable display is performed.

  In this normal display control, an image (symbol or character) including a stereoscopic image is displayed, but the auxiliary light source 814 is turned off in step S22 immediately before switching from the planar image (demo image) to the stereoscopic image. Therefore, crosstalk does not occur in the left and right images.

  Next, FIG. 9 shows a subroutine for display control of the jackpot screen performed in step S11 of FIG.

  First, in step S31, it is determined whether or not the display command signal received from the game control device 100 is a jackpot occurrence (giving a special game value), and in the case of a jackpot occurrence, the process proceeds to step S32. Otherwise, the process proceeds to step S34.

  In step S34, it is determined whether or not the display command signal received from the game control device 100 is a jackpot end. If the jackpot is ended, the process proceeds to step S35. Otherwise, the jackpot screen is displayed. It is determined that control is in progress (during a big hit game) and the process proceeds to step S35.

  If a big hit has occurred, first, in step S32, the drawing of the three-dimensional image (stereoscopic image) is stopped and the drawing mode is switched to the drawing mode of the two-dimensional image (planar image). That is, drawing is performed so that the same image without parallax is displayed in the right-eye image and the left-eye image.

  In step S33, the control signal LMP # CTL (see FIG. 2) is turned on to turn on the auxiliary light source 814 in order to turn on (emit) the auxiliary light source 814 that was turned off during the variable display game.

  Next, during the jackpot screen display control, the determinations in steps S31 and S34 are NO, and thus the light emission control and the display control are performed so as to maintain the state set when the jackpot occurs.

  Then, when the jackpot game ends, the process proceeds from step S34 to step S35, and control at the end of the jackpot is performed.

  In the case of the big hit, the control signal LMP # CTL is set to OFF and the auxiliary light source 814 is turned off in step S35 in order to turn off the auxiliary light source 814 that has been turned on.

  In step S36, the display mode is switched to a drawing mode permitting drawing of a three-dimensional image, and the subsequent display is performed using a three-dimensional image or a two-dimensional image corresponding to display control information (command) from the game control device 100.

  As a result, in the big hit, the auxiliary light source 814 is turned on and the brightness of the screen of the variable display device 8 is increased, and the viewing angle is increased by the diffused light. Information about the jackpot made up of the design of the device 8, the number of rounds or the number of counts can be easily confirmed by a two-dimensional image. It is possible to easily confirm information (for example, symbols) on the jackpot from other than the range), and the employee can display the variable display device from a predetermined imaging position on behalf of the player as in the conventional example. It is no longer necessary to visually recognize the player, and the player is not bothered.

  In this way, when the gaming state becomes a big win or a specific state of waiting for customers, the auxiliary light source 814 is turned on and the displayed image is switched from a stereoscopic image to a planar image. It is possible to easily view the image from other than the image position, and in the case of jackpot, the employee of the game shop can check the jackpot symbol from any position such as the side of the player, In the case of waiting for a customer, the auxiliary light source 814 can make a demo screen easily visible to a visitor walking in the aisle through a two-dimensional image (planar image) having a wide luminance and viewing angle. Can be aroused.

  Incidentally, since the process of lighting the auxiliary light source 814 in step S33 is performed after the drawing mode is changed in step S32, the three-dimensional image is prevented from reaching both eyes of the player by the light from the auxiliary light source 814. This prevents the occurrence of crosstalk. For the same reason, after the auxiliary light source 814 is turned off in step S35, the drawing mode is switched in step S36.

  In the above embodiment, the auxiliary light source 814 is a plurality of point light sources. However, the auxiliary light source 814 may be a surface light source or a line light source. Further, as described above, not only the method of lighting the light emitting element 810 as the main light source while the auxiliary light source 814 is turned on, but also the luminance of the light source element 810 of the main light source is reduced during the period when the auxiliary light source 814 is turned on. Alternatively, the duty ratio may be set so as to be turned off. By dimming or turning off the light emitting element 810 of the main light source, the amount of heat generated by the entire light source unit can be suppressed, and an increase in power consumption can be suppressed.

  As described above, in the first embodiment, although the auxiliary light source 814 provided separately from the light emitting element 810 as the main light source has an effect of widening the viewing angle of the image of the variable display device 8, At the same time, in the first embodiment, the effect of brightening the screen of the variable display device 8 by turning on the auxiliary light source 814 is also achieved. In the second embodiment below, control for brightening the screen of the variable display device 8 without providing the auxiliary light source 814 will be described.

  10 and 11 show the second embodiment, omitting the auxiliary light source 814 and the lamp driver 183 of the first embodiment, while changing the luminance of the light emitting element 810 of the main light source in the display control of the big hit screen. At the same time, the display content during the jackpot game is changed. In addition, the same code | symbol is attached | subjected to the thing similar to the said 1st Embodiment, and duplication description is abbreviate | omitted.

  First, the optical system shown in FIG. 10 is obtained by deleting the auxiliary light source 814 shown in FIG. 3 of the first embodiment, and an image is displayed by light transmitted through the liquid crystal display panel 804 from the light emitting element 810 as the main light source. Done.

  For this reason, although not shown, the lamp driver 183 shown in FIG. 2 of the first embodiment is also deleted.

  Next, FIG. 11 performs display control of the jackpot screen similarly to the flowchart shown in FIG. 9 of the first embodiment, and instead of blinking the auxiliary light source 814, the duty ratio of the light source element 810 of the main light source And the drawing pattern is changed.

  First, in step S41, it is determined whether or not the display command signal received from the game control device 100 is a jackpot occurrence. If the jackpot occurs, the process proceeds to step S42. If not, the process proceeds to step S44. move on.

  In step S44, it is determined whether or not the display command signal received from the game control device 100 is a jackpot end. If the jackpot is ended, the process proceeds to step S45. Otherwise, the jackpot screen is displayed. It is determined that control is in progress (during a big hit game), and the process proceeds to step S45.

  When a big hit occurs, first, in step S42, the display of the big hit symbol is switched to a two-dimensional image, and a character for production is displayed as a three-dimensional image, and the background coloring is relatively compared to the symbol. Set it dark.

  Next, in step S43, the duty ratio of the light emitting element 810 of the main light source is set to a value increased to a predetermined value (for example, 50% (ON duty)). In step S47, the light emitting element 810 is driven with the duty ratio set in step S43, and the luminance is increased with a higher duty ratio than in the normal display control to increase the amount of light.

  Further, in step S48, the display of the jackpot symbol is displayed as a two-dimensional image based on the drawing pattern set in step S42, while the effect character or the like is displayed as a three-dimensional image, and the background is simultaneously displayed. Draw darker than usual. More specifically, the background is drawn by changing the color information associated with the background image by the VDC 156 to one having lower brightness. Alternatively, a method may be used in which data of both a light background image and a dark background image are stored in the font ROM 157 and the corresponding background image is selected according to the drawing pattern.

  Next, during the jackpot screen display control, the determinations in steps S41 and S44 are NO, so that the state (duty ratio, drawing pattern) set when the jackpot is generated is maintained after step S47. Light emission control and display control are performed.

  Then, when the jackpot game ends, the process proceeds from step S44 to step S45, and control at the end of the jackpot is performed.

  When the big hit is completed, first, in step S45, display of a symbol in a three-dimensional image is permitted, and normal display control is set to restore the background to normal coloring.

  Next, in step S46, the duty ratio of the light emitting element 810 of the main light source is set to a value reduced to a predetermined value (for example, 25%) for normal display control. In step S47, the light emitting element 810 is driven at the duty ratio set in step S43, and the luminance is lowered by a lower duty ratio than during the display of the big hit screen, thereby reducing the light quantity.

  Further, in step S48, based on the drawing pattern set in step S42, the display of symbols on the two-dimensional image is permitted, and the background is switched to the normal one for drawing.

  As a result, when a jackpot is generated, the luminance of the light source element 810 of the main light source increases and information on the jackpot, such as a pattern that a game shop employee wants to check, is forcibly displayed as a two-dimensional image. By increasing the light amount of 810, it is possible to visually recognize more easily than in a normal game, and characters and the like that produce jackpots are displayed in a three-dimensional image, so that the player can enjoy a stereoscopic image. The jackpot game can be continued.

  Moreover, in addition to forcibly switching the drawing pattern of the symbol to a two-dimensional image, the background of the symbol or the like can be improved by making the background relatively dark, and this information can be improved on the player's side. Can be easily and accurately visually recognized from the direction or from above, improving the work efficiency of the game store employee and preventing the player from feeling uncomfortable by the check operation of the game store employee.

  In the customer waiting control in this case, the light emitting device 810 is driven at a higher duty ratio (for example, 100% or overdrive (voltage rise)) than that during the display control of the big hit screen, thereby further increasing the distance. What is necessary is just to improve visibility, such as a demo screen.

  FIGS. 12 and 13 show a third embodiment, in which a second display device 40 for displaying jackpot related information is provided at the top of the front frame 3 when a jackpot is generated or during a jackpot game. However, the jackpot-related information can be easily visually recognized, and the auxiliary light source 814 and the lamp driver 183 of the first embodiment are omitted. In addition, the same code | symbol is attached | subjected to the thing similar to the said 1st Embodiment, and duplication description is abbreviate | omitted.

  The second display device 40 provided on the upper portion of the front frame 3 (above the game board 6) is driven by the display control device 150 to display jackpot related information. For example, in FIG. The symbol display unit 41 displays a symbol (“777” in the example in the figure) that is a big hit from the left in the figure, and the current number of rounds (in the example in the figure, “R10” is the tenth round). Round number display section 42 indicating the number of winning balls to the big winning opening (C5 in the example of the figure, 5 balls) is configured.

  Next, as shown in FIG. 13, the display control device 150 displays the symbol, the number of rounds, and the number of counts that are a big hit based on a control signal (DATA) from the CPU 151. The second display device 40 includes a drive circuit such as an LED.

  Next, the optical system of the variable display device 8 is the same as that of FIG. 10 of the second embodiment, except that the auxiliary light source is excluded from the stereoscopic viewing optical system shown in FIG. 3 of the first embodiment. Even in such a case, the liquid crystal display panel 804 is illuminated by the light from the light source 810 that has passed through the polarizing filter 811, and a three-dimensional image can always be displayed.

  In this embodiment, the luminance of the liquid crystal display panel 804 does not change even if the jackpot is reached, but the jackpot symbol (identification information), the number of rounds in the jackpot game, and the number of counts are distributed separately from the variable display device 8. Since it is displayed by the second display device 40 provided, the game shop employee does not need to see the variable display device 8 for displaying the three-dimensional image, and therefore depends on the field of view of the liquid crystal display panel 804. By simply looking at the second display device 40 composed of only two-dimensional images, the jackpot state can be easily confirmed, and the work efficiency can be improved.

  In addition, although the case where the second display device 40 is configured with 7-segment LEDs is shown here, the present invention is not limited to this, and an arbitrary display device such as a liquid crystal display device or an EL or PDP panel can be adopted. it can.

  In the above embodiment, the case where the display control device 150 determines the waiting state for the customer is shown. However, the game control device 100 determines the waiting state for the customer and displays the waiting screen for the customer on the display control device 150. The auxiliary light source 814 may be instructed to turn on.

  Further, in the above-described embodiment, the waiting state is determined from the game ball firing state, but a sensor (sitting state detecting means) for detecting whether or not the player is seated, for example, an infrared sensor or a seat The presence / absence of a player may be determined using a pressure sensor or the like provided to the player, and the presence / absence of a player can be determined with higher accuracy.

  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.

  In addition, the following can be given as typical ones of the aspects of the present invention other than those described above.

(1) The display area of the liquid crystal panel illuminated by the backlight is provided with a left-eye image area and a right-eye image area, respectively, and from the backlight that transmits the left-eye image area and the right-eye image area. A display device comprising optical means for allowing light to independently enter the left and right eyes of the player;
Fluctuation display control means for fluctuating and displaying a plurality of types of identification information as a three-dimensional image or a planar image in the display area of the display device,
Special game state control means for generating a special game state capable of giving a privilege to the player when the variable display game derives a specific result mode;
In a gaming machine equipped with
An auxiliary light source that irradiates the liquid crystal panel and causes the irradiation light to pass through the image area for the left eye and the image area for the right eye and to enter both eyes of the player;
Specific state determining means for determining whether or not the gaming state is in a specific state different from the normal gaming state;
When it is determined that the specific state determination unit is in the specific state, a specific state display control unit that displays a preset image corresponding to the specific state in the display area and lights the auxiliary light source; A gaming machine characterized by comprising:

  In the invention of (1), in the first invention, the liquid crystal panel is illuminated by light from a backlight (main light source) in a variable display during a game, and the game state is different from a normal state (for example, waiting for a customer). When a state or a big hit occurs), an image including a planar image is displayed, the auxiliary light source is also turned on, and the liquid crystal panel is illuminated.

  For this reason, in a specific state, the brightness of the screen of the display device (the amount of light transmitted through the liquid crystal panel) is greatly increased, and the viewing angle of the display device is increased by the light from the auxiliary light source.
