  The card lending unit 2 includes 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.

  FIG. 2 is a block diagram showing a part of a control system centering on the game control device 100 of the gaming machine according to the embodiment of the present invention.

  The game control device 100 is a main control device that controls the game in an integrated manner, 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 gaming microcomputer 101 with a built-in, an input interface 102, an output interface 103, an oscillator 104, and the like.

  The gaming microcomputer 101 has various detection devices (general winning opening sensors 51.1 to 51.N, special symbol start sensor 52, normal symbol start sensor 53, count sensor 54, continuation sensor 55) via the input interface 102. In response to the detection signal from, various processes such as a big win lottery are performed. And, via the output interface 103, various control devices (production control device 150, discharge control device 200, decoration control device 250, sound control device 300), normal symbol display 7, normal electric accessory solenoid 9A, large prize opening A command signal is transmitted to the solenoid 10A or the like to control the game in an integrated manner.

  The discharge control device 200 controls the operation of the payout unit based on the prize ball command signal from the game control device 100 and discharges the prize ball. Further, based on the ball rental request from the card ball rental unit 2, the operation of the payout unit is controlled to discharge the ball rental.

  Based on the command signal from the game control device 100, the decoration control device 250 is a decoration light emitting device such as a decoration lamp or LED (decoration lamp in the center case 11, decoration lamp in the attacker, side lamp 33, side case lamp. The game frame decoration lamp, the notification lamp 31 and the like), and the display of the normal symbol winning memory display 19 is controlled to function as a lamp LED control device.

  The sound control device 300 functions as a sound control device by controlling sound effects output from the speaker.

  In this embodiment, the decoration control device 250, the sound control device 300, and the effect control device 150 are provided separately. However, the decoration control device 250, the sound control device 300, and the effect control device 150 are configured integrally. Also good.

  Communication from the game control device 100 to various subordinate control devices (the effect control device 150, the discharge control device 200, the decoration control device 250, and the 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.

  A power supply device (not shown) of the gaming machine includes a backup power supply unit and a power failure monitoring circuit in addition to the power supply circuit. When the power failure monitoring circuit detects a predetermined voltage drop of the power supply device, the power failure monitoring circuit sequentially outputs a power failure detection signal and a reset signal to the game control device 100 and the like. When the game control device 100 receives a power failure detection signal, the game control device 100 performs a predetermined power failure process, and when it receives a reset signal, stops the operation of the CPU. The backup power supply unit supplies backup power to the RAM of the game control device 100 or the like to back up game data (including game information, game control information: variable display game information) and the like.

  The effect control device 150 performs image display control, and functions as an effect control means together with the game control device 100 and the composite conversion device 170. The effect 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 clock signal 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 alternately generate the image signal for the right eye and the image signal for the left eye. An L / R signal is generated in accordance with the generation timing of the right-eye image signal and the left-eye image signal, and it is identified whether the generated image signal is a right-eye image signal or a left-eye image signal. It is possible.

  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 period 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 generates a composite conversion device 170 and an image. It is output to the display device 8.

  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 image display device 8, adjusts the display illuminance of the image display device 8, and generates an RGB signal to be output to the image display device 8. .

  Further, the CPU 151 of the effect 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 luminance (the amount of light emitted from the backlight) of the image display device 8 based on the state of variable display (for example, whether it is a normal variable display game or a jackpot display) and the state of the game. Therefore, the duty control signal DTY_CTR is generated based on the clock signal of the oscillator 158 and output to the image display device 8.

  Based on the L / R signal output from the CPU 151, the composite conversion device 170 determines whether the image signal sent from the VDC 156 is a right-eye image signal or a left-eye image signal. The synthesizing / conversion device 170 includes a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer. The determined right-eye image signal is written to the right-eye frame buffer, and the left-eye image signal is written. Write to the left eye frame buffer. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, the stereoscopic image signal is written in the stereoscopic frame buffer, and the stereoscopic image data is converted into an RGB signal as an image display device. 8 is output.

  As will be described later, the right-eye image and the left-eye image are obtained for each horizontal line (scanning line) of the display unit of the liquid crystal display by the stereoscopic image signal obtained by combining the right-eye image and the left-eye image. Stereoscopic images are displayed so as to be displayed alternately.

  Specifically, the right eye image and the left eye image are generated with parallax based on the depth information of the stereoscopic image information (display object). In the case of polygon drawing, rendering is performed with a left-eye viewpoint and a right-eye viewpoint to generate a right-eye image and a left-eye image, respectively. When using sprite data, drawing is performed by shifting in the left-right direction by the amount of parallax.

  In this way, the left-eye image and the right-eye image are alternately generated, and the left-eye image is stored in the left-eye frame buffer, and the right-eye image is stored in the right-eye frame buffer. That is, 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 for each scanning line are read and written into the stereoscopic frame buffer.

  When the CPU 151, the VDP 156, and the composite conversion device 170 function as described above, a left-eye image and a right-eye image are generated, and binocular parallax occurs depending on the display position, and the image is recognized as a three-dimensional stereoscopic image. The display position control means is configured by controlling the display as described above.

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

  The backlight driver 182 changes the brightness ratio of the image display device 8 by changing the duty ratio of the voltage applied to the backlight based on the DTY_CTR signal output from the VDC 156.

  In other words, the game control device 100 extracts and stores a predetermined random number (special symbol random number, jackpot random number) when a game ball launched into the game area wins the start opening 16. Then, the game control device 100 edits the display control command signal that instructs the effect control device 150 to change display, and transmits the edited display control command signal. When receiving the display control command signal, the CPU 151 of the effect control device 150 reads display image data corresponding to the display control command signal from the font ROM 157 (storage means), and cooperates with the VDC 156 and the composite conversion device 170. Display data to be displayed on the image display device 8 is generated. Thus, the lottery means and the game control means are configured by the function of the game control device 100. Further, the effect control device 150 and the composite conversion device 170 function to constitute a calculation means.

  A buffer circuit 160 serving as a signal transmission direction restricting means is provided in front of the interface 155 that receives the effect control command signal from the game control device 100, and only signal input from the game control device 100 to the effect control device 150 is allowed. Thus, signal output from the effect control device 150 to the game control device 100 is prohibited. Note that when performing bidirectional communication between the game control device 100 and the effect control device 150, a bidirectional buffer may be used for the buffer circuit 160.

  The LED 34 is turned on while the three-dimensional stereoscopic image is displayed, and is controlled by the CPU 151 to be turned on / off by applying a voltage to the LED 34 via the driver 161. That is, when a stereoscopically visible image is displayed on the image display device 8, the display mode is changed (for example, it is turned on or the emission color is changed) to display stereoscopically. To the player.

  In addition, it can also comprise so that a player's stereoscopic vision may be assisted by carrying out the auxiliary display which gives a feeling of depth to the near side of the image display apparatus 8 by lighting of LED34.

  The effect control device 150 may be configured by including the decoration control device 250 and the sound control device 300 in the effect control device 150 among the subordinate control devices described above.

  FIG. 3 is an explanatory diagram showing the configuration of the image display apparatus according to the embodiment of the present invention.

  The light source 801 includes a light emitting element 810, a polarizing filter 811, and a Fresnel lens 812. The light-emitting element 810 is configured by using white light-emitting diodes or the like that are arranged side by side in the form of point light sources, or by horizontally arranging linear light sources such as cold-cathode tubes. 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 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 passing through the right region 811a of the polarizing filter 811 and the light passing through the left region 811b are irradiated to the Fresnel lens 812 as differently polarized light. As will be described later, the light that has passed through the right region 811a of the polarizing filter 811 reaches the left eye of the observer, and the light that has passed through the left region 811b reaches the right 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 the light radiated from the light emitting element 810 substantially in parallel and transmits it through the fine retardation plate 802, and the liquid crystal display panel 804 (fine level). The phase difference plate 802) is irradiated.

  At this time, the light irradiated from 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 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 in different directions on the left and right.

  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 (first polarizing plate) are disposed on the light source 801 side of the liquid crystal display panel 804, and a polarizing plate 805 (second polarizing plate) is disposed on the viewer side. Yes.

  In the fine retardation plate 802, regions where the polarization of transmitted light is different 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 regions 802b where the two-wavelength plate 821 is not provided are alternately provided at fine intervals. 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. This half-wave plate 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 axis of the light transmitted through the right region 811a is rotated by 90 degrees so as 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 that has passed through the left region 811b, and the region 802a where the half-wave plate 821 is provided. Light that has passed through the right region 811 a and whose polarization axis is orthogonal to the polarizing plate 803 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 corresponding to each horizontal line (scanning line) of the display unit of the liquid crystal display panel 804 are different, and the direction of the emitted light is different for each horizontal line.

  Alternatively, the polarization characteristic of the fine retardation plate 802 is repeated as an integer 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 (ie, a plurality of display units It is set so that the polarization of the transmitted light is different for each of the plurality of display units. Therefore, 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.

  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 light transmits the light transmitted through the right region 811a of the polarizing filter 811 with the same polarization as 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 first polarizing plate and has a polarization characteristic that transmits light having the same polarization as the light transmitted through the fine retardation plate 802. That is, the light transmitted through the left region 11b of the polarizing filter 811 is transmitted through the first polarizing plate 803, and the light transmitted through the right region 11a of the polarizing filter 811 is rotated through the polarization axis by 90 degrees to pass through the first polarizing plate 803. To Penetrate. In addition, the polarizing plate 805 functions as a second polarizing plate and has a polarization characteristic that transmits 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. 8 is configured. At this time, when a voltage is applied to the liquid crystal, the liquid crystal molecules of the liquid crystal display panel 804 are aligned, so that the light transmitted through the fine retardation plate 802 is transmitted through the polarizing plate 805. On the other hand, in the state where no voltage is applied to the liquid crystal, the liquid crystal molecules of the liquid crystal display panel 804 are twisted and oriented by 90 degrees, so that the light transmitted through the fine retardation plate 802 is twisted by 90 degrees and the liquid crystal display panel 804 is twisted. Is not transmitted through the polarizing plate 805.

  Note that the polarization characteristic of the polarizing plate (first polarizing plate) 803 is equal to that of the polarizing plate 822 used as the base material of the fine retardation plate 802, and only light that can be transmitted through the polarizing plate 803 is polarized. Since the light is transmitted through the plate 822, the light with uniform polarization may be incident on the liquid crystal display panel 804 by the polarizing plate 822 used as the base material of the fine retardation plate 802 without providing the polarizing plate 803. Good.

  The diffuser 806 is attached to the front surface (observer side) of the second polarizing plate 805 and functions as a diffusing unit that diffuses light transmitted through the liquid crystal display panel in the vertical direction. Specifically, the 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.

  FIG. 4 is a plan view showing an optical system of the image display apparatus according to the embodiment of the present invention.

  As shown in FIG. 4, the light emitted from the light emitting element 810 is transmitted radially through the polarizing filter 811. Of the light emitted from the light source, the light transmitted through the right region 811a of the polarizing filter 811 (the center of the optical path is indicated by a one-dot chain line) reaches the Fresnel lens 812, and the traveling direction of the light is changed by the Fresnel lens 812. The light passes through the fine retardation plate 802, the polarizing plate 803, the liquid crystal display panel 804, and the polarizing plate 805 substantially vertically (slightly from the right side to the left side) and reaches the left eye.

  On the other hand, of the light radiated from the light source, the light transmitted through the left region 811b of the polarizing filter 811 (the broken line indicates the center of the optical path) reaches the Fresnel lens 812, and the traveling direction of the light can be changed by the Fresnel lens 812. 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 substantially vertically (slightly left to right) and reaches 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 substantially perpendicularly 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 polarization planes substantially vertically and through different paths, and transmitted through the liquid crystal display panel 804. Light is emitted in different ways to reach the right or 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.

  That is, the light emitted from the light emitting element 810 and transmitted through the right region 811a of the polarizing filter is transmitted through the Fresnel lens 812, reaches the fine retardation plate 802, and is emitted after rotating the polarized light by 90 degrees (right region). The light transmitted through 811a is transmitted through the region 802a of the fine retardation plate 802, and further transmitted through the polarizing plate 803, the liquid crystal display panel 804, and the polarizing plate 805 to reach the left eye. That is, the left eye image displayed by the display element at a position corresponding to the region 802a of the liquid crystal display panel 804 reaches the left eye.

  Since the regions 802 b arranged alternately with the regions 802 a of the fine retardation plate 802 do not change the polarization of the transmitted light, the light from the right region 811 a of the polarizing filter does not pass through the polarizing plate 803. The right eye image displayed on the display element at the position corresponding to the region 802b of the liquid crystal display panel 804 does not reach the left eye.

  On the other hand, the light emitted from the light emitting element 810 and transmitted through the left side region 811b of the polarizing filter passes through the Fresnel lens 812 and reaches the fine retardation plate 802, and the light having the same polarization as the left side region 811b of the polarizing filter is emitted. The light passes through the region 802b of the fine retardation plate 802 that passes through, passes through the liquid crystal display panel 804 and the polarizing plate 805, and reaches the right eye. That is, the right eye image displayed by the display element at a position corresponding to the region 802b of the liquid crystal display panel 804 reaches the right eye.

  Since the regions 802a arranged alternately with the regions 802b of the fine retardation plate 802 change the polarization of the transmitted light, the light from the left region 811b of the polarizing filter does not pass through the polarizing plate 803. The left-eye image displayed on the display element at the position corresponding to the region 802a of the liquid crystal display panel 804 does not reach the right eye.

  FIG. 5 is a diagram illustrating the appearance position of a stereoscopic image in the image display device 8 according to the embodiment of the present invention.

  FIG. 5A shows a state in which a two-dimensional planar image is displayed. The right-eye image and the left-eye image are displayed on the display screen at the same position without causing binocular parallax. That is, since an image without binocular parallax is displayed on the image display device 8, the display screen is the appearance position of the image.

  FIG. 5B shows a state in which the three-dimensional stereoscopic image is displayed at a position on the near side of the display surface, and the right-eye image and the left-eye image are displayed on the display screen at a distance of parallax x1. That is, since the image display device 8 displays an image with binocular parallax in which the right-eye image is shifted to the left side and the left-eye image is shifted to the right side, the stereoscopic image is positioned on the near side by y1 from the display screen. Appears as if jumps out.

  FIG. 5C shows a state in which the three-dimensional stereoscopic image is displayed at a position deeper than the display surface. The right eye image and the left eye image are separated from each other by a parallax x2 on the display screen (see FIG. 5B). It is displayed with parallax in the opposite direction to the state shown. That is, since the image display device 8 displays an image with binocular parallax in which the right-eye image is shifted to the right side and the left-eye image is shifted to the left side, the stereoscopic image is positioned on the back side by y2 from the display screen. Appears.

  The binocular parallax is determined by how many display units (dots) of the liquid crystal display panel 804 are shifted to display the right eye image and the left eye image. In the range where the number of shifted dots is small (several dots), the number of dots and the three-dimensional image are determined. The amount of movement before and after the appearance position of is substantially proportional. That is, in FIG. 5, when the shift directions of the left eye image and the right eye image are different and the shift amount is the same (x1 = x2), the appearing three-dimensional image has the same amount (y1 = y2) from the reference position (display screen). ) Appears at a position shifted forward and backward.

  Thus, when displaying a stereoscopically viewable image using parallax, the same image is used for the left eye image and the right eye image, and the display positions of the left eye image and the right eye image are changed and displayed with parallax. A case where different images (for example, an image viewed from the left eye position and the right eye position) are used for the left eye image and the right eye image, and the display positions of the left eye image and the right eye image are changed and displayed with parallax. There is.

  FIG. 6 is a flowchart showing the start winning prize monitoring process for the gaming machine according to the embodiment of the present invention, which is executed by the game control device 100.

  The game control device 100 determines whether or not a game ball has won the starting port 7 based on a winning detection signal from the special symbol starting sensor 14 (S101).

  When the special symbol start sensor 14 detects a winning of a game ball at the start port 7 (“YES” in S101), the number of special symbol winning memories to be added corresponding to the winning and the predetermined predetermined number of winning memory To determine whether or not the number of special symbol winning memories has reached a predetermined upper limit, that is, whether or not there is an empty winning memory (S102). If the winning memory has reached the predetermined upper limit and there is no free space in the special symbol winning memory ("NO" in S102), the detected winning at the start port 7 cannot be stored. The variable display game is not played, and the start winning prize is discarded.

  On the other hand, if the winning memory does not reach the predetermined upper limit (if there is an empty winning memory: “YES” in S102), it corresponds to the winning memory in order to execute the variable display game regarding the detected start winning. The random number which determines the mode of the variable display game to be extracted is extracted (S103, S104). In S103, the special symbol random number counter value provided in the game control device 100 is extracted by the start winning timing detected by the special symbol start sensor 14. This special symbol random number counter value is used to determine whether or not the result of the variable display game is a big hit.

  In S104, the value of the jackpot symbol random number counter provided in the game control device 100 is extracted based on the start winning timing detected by the special symbol start sensor 14. This jackpot symbol random number counter value determines a stop symbol derived as a result of the variable display game when the result of the variable display game is a big hit, and is related to the determination of whether or not the probability variation state is entered. .

  Then, the extracted special symbol random number counter value and jackpot symbol random number counter value (or the determination result of the special symbol random number counter value and jackpot symbol random number counter value) are stored as special symbol winning memory (S103, S104).

  Then, the game control device 100 adds 1 to the special symbol winning memory number data provided in the special symbol winning memory area and updates the special symbol winning memory number (S105).

  FIG. 7 is a flowchart showing the change display command editing process of the gaming machine according to the embodiment of the present invention, which is executed by the game control device 100.

  As described above, the special symbol random number counter value and the jackpot symbol random number counter value extracted by winning the game ball at the start port 7 are stored as the special symbol winning memory. Then, when the variable display game ends or when the big hit game ends and the next variable display game is started, the game microcomputer 101 of the game control device 100 reads the special symbol random number from the special symbol winning storage area. In order to read the counter value and execute the variable display game corresponding to the special symbol random number counter value, the random display pattern random number counter value is extracted, and the variable display pattern selection stored in the ROM of the gaming microcomputer 101 is selected. The variable display pattern is selected with reference to the table, and the variable display command (display control command signal) to be transmitted to the effect control device 150 is selected (S111). This variable display pattern selection table is provided for each gaming state with a notice, no notice, final notice, etc., and the table is changed according to the game state to change the probability that a variable display pattern (variable display command) is selected. Select the fluctuation display pattern (fluctuation display command). In the variable display command selection process shown in FIG. 7, different tables are selected depending on the special symbol random number counter value and the continuous notice state.

  And the game control apparatus 100 determines a stop symbol (S112). There are a plurality of methods for determining the stop symbol. First, when the special symbol random number counter value stored as the winning memory is a value for deriving the jackpot, the symbols whose identification information is aligned and stopped by the jackpot symbol random counter value extracted at the time of starting winning (the jackpot symbol) To decide.

  Further, when the special symbol random number counter value stored as the winning memory is not a value for deriving the jackpot, the variation display pattern is determined by the variation display pattern determination random number counter value extracted when the variation start condition is established, An appropriate stop symbol combination pattern is instructed to the variable display pattern, and the stop symbol is determined based on the instruction and the stop symbol determining random number.

  For example, when a normal variation pattern for deriving a completely lost symbol that does not generate reach is selected, a random symbol value for determining the left symbol that is extracted and updated periodically and stored in the RAM of the gaming microcomputer 101, The left symbol, the middle symbol, and the right symbol are determined as the stop symbols from the symbol determining random number value and the right symbol determining random value. If the combination of symbols constitutes a reach mode or a jackpot mode in the extraction of the left, middle, and right symbol determination random numbers, these symbol determination random numbers are discarded, and at the next extraction timing, A new combination is determined.

  In addition, when a reach variation pattern is selected in which the left and right symbols are aligned and the middle symbol is removed, the left symbol is determined from the left symbol determination random value, the same symbol as the left symbol is selected as the right symbol, and the middle symbol is Using the reach determining symbol random number for determining the number of symbols shifted from the left and right symbols, the middle symbol is determined by adding the reach determining symbol determining random number to the left symbol.

  Then, the game control device 100 edits the variation display command corresponding to the determined variation display pattern (S113), and transmits the variation display command to the effect control device 150 (S114).

  8 to 13 are diagrams showing display examples in the variable display of the gaming machine according to the embodiment of the present invention.

  FIG. 8 shows the state of identification information (symbols) before the start of variable display. Before starting the variable display, the left symbol “5” is displayed in the lower left portion of the display screen, the middle symbol “8” is displayed in the center portion of the display screen, and the right symbol “6” is displayed in the upper right portion of the display screen. In other words, even when each symbol is scrolled horizontally, each symbol is placed in a position that is shifted in the vertical direction in a state where each symbol can be recognized (a state where each symbol can be recognized while overlapping). Has been.

  FIG. 9 shows the state of the identification information (design) during the variable display (after the variable display is started). Each of the symbols on the left, middle and right scrolls in the horizontal direction and switches to the next symbol in order to display the variation. At this time, the left symbol is variably displayed in the horizontal direction at the lower part of the display screen, the middle symbol is at the center of the display screen, and the right symbol is at the upper part of the display screen. Each symbol is displayed as a two-dimensional flat image, with the left symbol on the foreground, the right symbol on the last surface, the middle symbol on the left symbol and the right symbol, part of the symbol overlapping. It is displayed.

  FIG. 10 shows the state of identification information (symbols) during fluctuation display (when the reach state is established).

  The left symbol is displayed at the lower left corner of the display screen, the right symbol is displayed at the upper right corner of the display screen, and both symbols are temporarily stopped with the same identification information “7”. This temporary stop state is a state in which the final stop symbol is not determined as a substantially stop state in which the player can recognize the symbol. Specifically, in addition to moving the symbol slightly (left and right or back and forth) at the stop position, the symbol is rotated, the symbol is scaled, the symbol color is changed, and the symbol shape There is a mode such as changing.

  Then, the left symbol pops out to the near side at the lower left portion of the display screen, and the right symbol is retracted to the far side at the upper right portion of the display screen, resulting in the state shown in FIG.

  FIG. 11 shows the state of identification information (symbol) during fluctuation display (when the reach state is established).

  The left design is displayed so that a 3D image appears at the position on the lower left side of the display screen, and is temporarily stopped, and the right design is a 3D image that appears in the back of the display screen at the upper right. Is displayed, and is temporarily stopped. At this time, the three-dimensional image of the left symbol and the right symbol are located at positions where the distance (d1) between the left symbol and the middle symbol in the depth direction and the distance (d2) between the right symbol and the middle symbol in the depth direction are substantially equal. Temporarily stops (see FIG. 12). In other words, the protruding amount of the left symbol stereoscopically viewed at the position protruding toward the front side is equal to the drawing amount of the right symbol stereoscopically viewed at the position retracted to the back side (the parallax amount and the right symbol related to the left symbol) The amount of parallax is the same amount and the reverse direction). The movement in the depth direction of the left design stereoscopic image and the right design stereoscopic image may be reduced in order to facilitate stereoscopic viewing.

  Further, if the symbol is temporarily stopped while holding the display position such as expansion / contraction or color change without moving the symbol, the possibility that the three-dimensional effect of the symbol is impaired is reduced. In addition, when a temporary stop is performed by fluctuation fluctuation, stereoscopic vision of the temporary stop symbol may be impaired by performing fluctuation fluctuation that moves in a direction (vertical direction) orthogonal to the parallax setting direction (horizontal direction). Decrease.

  The middle symbol is scrolled horizontally between the right symbol and the left symbol (on the display surface). The scroll of the middle symbol may be displayed at the reference position (that is, the middle symbol is displayed as a two-dimensional plane image on the display screen), or the position between the right symbol and the left symbol in the depth direction. A three-dimensional image may be displayed so that a three-dimensional image appears. In addition, if the middle symbol that is being scrolled is displayed as a two-dimensional planar image, it is possible to suppress the loss of stereoscopic vision, and the restriction on the scroll speed at which the symbol can be recognized is reduced, and the symbol is displayed at various speeds. Can be scrolled.

  In addition, part of the middle symbol is hidden behind the left symbol, and part of the right symbol is hidden by the middle symbol, and overlaps with the part of the left and right symbols, so that the left symbol, middle symbol, right It is easy to perceive the order in the depth direction where the symbols are arranged. As the middle symbol moves, move the right symbol displayed on the back side in the opposite direction to the middle symbol at a slow speed, and move the left symbol displayed on the near side in the same direction as the middle symbol at a high speed. Alternatively, it may be displayed so as to give motion parallax between the symbols. In this way, stereoscopic vision of each symbol is assisted by motion parallax.

  In the depth direction, the middle symbol is displayed at the middle position between the right symbol and the left symbol, and the same symbol as the previously stopped symbol (left symbol, right symbol) is displayed and stopped, and the big hit state is derived. .

  FIG. 13 shows the state of the identification information (symbol) when the variable display ends and the jackpot is confirmed. Each of the middle left and right symbols is displayed as a two-dimensional plane image on the display screen. In other words, in the reach state in which the previously stopped symbols (left symbol and right symbol) are in a state of being aligned, the symbols that have been displayed in a stereoscopic view and stopped are confirmed when the jackpot state is confirmed. The stereoscopic state ends and is displayed by a two-dimensional planar image.

  In the variable display examples shown in FIGS. 8 to 13, the left symbol is displayed on the near side and the right symbol is displayed on the far side. On the contrary, the right symbol is on the near side. The left symbol may be displayed so as to be stereoscopically viewed on the back side. Further, the changing direction of the symbols is not limited to horizontal scrolling, and may be vertical scrolling, or may be variable display by switching the symbols in a state where the symbol display position is fixed.

  FIG. 14 is a timing chart showing changes in the display mode of the identification information described in FIGS.

  Both the left and right symbols are displayed as a two-dimensional planar image before starting the variable display. When the variation display game starts, each symbol moves identification information and starts variation display for switching identification information. Thereafter, the identification information is moved at a slow speed, and the process shifts to low-speed fluctuation for switching the identification information. The symbols (left symbol and right symbol) that form the reach state at the switching timing of the changing speed shift from the display by the two-dimensional plane image to the display by the three-dimensional stereoscopic image.

  Then, the symbols that are stopped first (the left symbol and the right symbol) are displayed as a three-dimensional stereoscopic image and temporarily stopped to form a reach state. At the timing of formation of the reach state, the symbols forming the reach (left symbol and right symbol) shift from the display by the two-dimensional plane image to the display by the three-dimensional stereoscopic image. Thereafter, the middle symbol stops and all symbols stop. Then, both the left and right symbols are shifted to display by a two-dimensional planar image. Although the depth position is switched between the 2D display screen and the 3D display screen, the 3D stereoscopic image displayed at the predetermined depth position is switched to the depth position with a larger amount of parallax and displayed. May be.

  FIG. 15 is another timing chart showing a change in the display mode of the identification information described in FIGS.

  Both the left and right symbols are displayed as a two-dimensional planar image before the start of variable display. When the variation display game starts, each symbol moves identification information at a high speed and starts high-speed variation for switching the identification information. Thereafter, the identification information is moved at a slow speed, and the process shifts to a low-speed fluctuation for switching the identification information. The symbols (left symbol and right symbol) that form a reach at the switching timing of the changing speed shift from the display by the two-dimensional plane image to the display by the three-dimensional stereoscopic image. In this way, if the symbol change speed is switched from high speed to low speed at the timing of switching to 3D stereoscopic image display, it is difficult to recognize a stereoscopic image if the symbol is moved at high speed, but the symbol is moved at low speed. 3D images can be easily recognized.

Then, the symbols having the same symbols (the left symbol and the right symbol ) to be stopped first are displayed as a three-dimensional stereoscopic image and temporarily stopped. Then, after the symbol (medium symbol) to be stopped last is continuously displayed by the two-dimensional planar image, the middle symbol is stopped and all symbols are stopped. Then, both the left and right symbols are shifted to display by a two-dimensional planar image. Although the depth position is switched between the 2D display screen and the 3D display screen, the 3D stereoscopic image displayed at the predetermined depth position is switched to the depth position with a larger amount of parallax and displayed. May be.

  FIG. 16 shows a variation of the variation display shown in FIGS. 8 to 13 and shows the state of identification information (design) during variation display (when the middle symbol is stopped after the reach state).

  In the above-described variation display example (FIG. 12), the middle symbol is displayed as a two-dimensional plane image, and the left symbol is displayed in the front side and the right symbol is displayed in the rear side so that it can be stereoscopically displayed. In the modification shown in FIG. 16, the left symbol is displayed as a two-dimensional plane image, and the middle symbol and the right symbol are displayed as a three-dimensional stereoscopic image that can be stereoscopically viewed on the back side.

  In this modified example, after the variable display of the left middle right symbol is started, the middle symbol and the right symbol display the same identification information, enter a temporary stop state, form a reach state, and the left symbol performs variable display. In this state, the middle symbol is displayed so that a three-dimensional image appears at a position retracted to the back side, and the right symbol is displayed so that a three-dimensional image appears at a position retracted further back than the middle symbol. The left symbol is scrolling the front side of the middle symbol. The left symbol may be displayed at the reference position (that is, the left symbol is displayed as a two-dimensional plane image on the display screen), or a stereoscopic image may appear at a position in front of the middle symbol in the depth direction. A three-dimensional stereoscopic image may be displayed.

  Then, the left symbol is displayed in front of the middle symbol, and as shown in FIG. 16, the same symbol as the previously stopped symbol (middle symbol, right symbol) is displayed and stopped. At this time, the left symbol stops at a position where the distance (d1) between the left symbol and the middle symbol in the depth direction is substantially equal to the distance (d2) between the right symbol and the middle symbol in the depth direction. That is, the drawing amount of the middle symbol stereoscopically viewed at the position retracted to the back side is half of the pulling amount of the right symbol stereoscopically viewed to the position retracted further to the back side than the middle symbol (the amount of parallax related to the right symbol) Is the same direction with twice the amount of parallax for the middle symbol).

  FIG. 17 shows a state of identification information (symbol) during variation display (when the middle symbol is stopped after the reach state) in the variation display variations shown in FIGS. 8 to 13. In the above-described variation display example (FIG. 12), the middle symbol is displayed as a two-dimensional plane image, and the left symbol is displayed in the front side and the right symbol is displayed in the rear side as a three-dimensional stereoscopic image. In the modification shown in FIG. 17, the right symbol is displayed as a two-dimensional planar image, and the left symbol and the middle symbol are displayed as a three-dimensional stereoscopic image so as to be stereoscopically viewed on the front side.

  In this modified example, after the left and right symbols are displayed in a variable manner, the left symbol and the middle symbol display the same identification information, enter a temporary stop state, form a reach state, and the right symbol displays a variation. In this state, the middle symbol is displayed so that a three-dimensional image appears at a position that protrudes toward the front side, and the left symbol is displayed such that a three-dimensional image appears at a position that protrudes further toward the front side than the middle symbol. The right symbol is scrolling the back side of the middle symbol. The right symbol may be displayed at the reference position (that is, the right symbol is displayed as a two-dimensional planar image on the display screen), or a stereoscopic image may appear at a position deeper than the middle symbol in the depth direction. A three-dimensional stereoscopic image may be displayed.

  Then, the right symbol is displayed on the back side of the middle symbol, and as shown in FIG. 17, the same symbol as the previously stopped symbol (left symbol, middle symbol) is displayed and stopped. At this time, the right symbol stops at a position where the distance (d1) between the left symbol and the middle symbol in the depth direction is substantially equal to the distance (d2) between the right symbol and the middle symbol in the depth direction. That is, the projection amount of the middle symbol stereoscopically viewed at the position protruding to the near side is half of the projection amount of the left symbol stereoscopically viewed to the position protruding further to the near side than the middle symbol (the amount of parallax related to the left symbol) Is the same direction with twice the amount of parallax for the middle symbol).

  As described above, in the embodiment described above, the image display device 8 that displays a stereoscopically visible image by the parallax effect between the left and right eyes, and the effect control device 150 that controls the variable display of a plurality of identification information (designs), In a gaming machine capable of generating a jackpot state that performs a variable display game that displays the symbols displayed on the image display device 8 in a variable manner and gives a specific game value in relation to the result mode of the variable display game. The control device 150 includes CPU 151, VDP 156, and a composite conversion device as display position control means for changing the display position of the left eye image and right eye image displayed on the image display device and controlling the appearance position of the stereoscopic image in the depth direction. The display position control means controls the appearance position of the plurality of symbols to be the same depth position at the start of the variable display game. In the reach state in which at least two of the symbols excluding the symbol that is being displayed in a variation display a combination that can cause a special gaming state, the depth position of the three-dimensional image of the symbol that is in the variable display is not changed. The appearance position in the depth direction of the three-dimensional image of the symbol forming the reach state is changed from the depth position at the start of the variable display game to the far side and the other to the near side. Since the depth position of the information is made equal to the depth position of the identification information that is variably displayed during the reach, the identifiability of the identification information that the player pays attention to during the variable display game does not deteriorate, It is possible to suppress a decrease in interest in the display game. In addition, since the symbols forming the reach state are displayed with the depth position being changed in the front-rear direction, the symbols forming the reach state can obtain a large depth difference and improve the stereoscopic effect. At this time, since the changing symbol is a depth position between the symbols forming the reach state, the depth difference between each symbol forming the reach state and the changing symbol is not excessive, and Stereo vision can be coordinated.
