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

  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 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 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 hit lottery are performed. And, via the output interface 103, commands are given to various control devices (production control device 150, discharge control device 200, decoration control device 250), normal symbol display 7, normal electric accessory solenoid 9A, special prize opening solenoid 10A, etc. Send a signal to control the game centrally.

  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.

  The decoration control device 250 (assistant control means) controls energization to a motor (or solenoid) as a drive means provided in the stereoscopic assistant 60 described later based on a command signal from the effect control device 150, The operation of the stereoscopic assistant 60 is controlled.

  Further, the decoration control device 250 is based on a command signal from the effect control device 150, such as 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 lamp A case lamp, a game frame decoration lamp, a notification lamp 31 and the like), and the display of the normal symbol winning memory display 19 is controlled.

  The decoration control device 250 controls sound effects output from the speakers.

  Note that only one-way communication from the game control device 100 to the subordinate control device is allowed for communication from the game control device 100 to the various subordinate control devices (the effect control device 150, the discharge control device 200, and the decoration control device 250). It has become so. 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 (assistant control means) controls the display of images, and functions as an effect control means together with 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 a program, and 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 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 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 light emission amount (luminance) of the image display device 8 based on the state of the variable display (for example, whether it is a normal variable display game or a big hit display) and the state of the game. The control signal DTY_CTR is generated based on the clock signal of the oscillator 158 and output to the image display device 8.

  The synthesizing / conversion device 170 is provided with a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer, writes the right-eye image sent from the VDC 156 to the right-eye frame buffer, and the left-eye image for the left-eye. Write to the frame buffer. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, which is written into the stereoscopic frame buffer, and the stereoscopic image data is output to the image display device 8 as an RGB signal.

  In the generation of the stereoscopic image by combining the right-eye image and the left-eye image, the right-eye image and the left-eye image are combined at intervals of a half-wave plate 521 of the fine retardation plate 502 described later. Since the half-wave plate 521 of the fine retardation plate 502 is arranged at intervals of the display unit of the liquid crystal display panel 504, the right-eye image and the right-eye image are displayed for each horizontal line (scanning line) of the display unit of the liquid crystal display panel 504. The stereoscopic image is displayed so that the left-eye image is 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 the amount of parallax in the horizontal direction.

  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 are read for each scanning line and written into the stereoscopic frame buffer.

  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 (LCD DRV) 181 sequentially applies voltages to the electrodes of the liquid crystal display based on the VBLANK signal, the V_SYNC signal, the H_SYNC signal, and the RGB signal sent from the composite conversion device 170 to the image display device 8. A composite image for stereoscopic viewing 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.

  The LED 34 is turned on during the operation of the stereoscopic assistant 60, is controlled by the CPU 151, and is turned on / off by a voltage applied to the LED 34 via the driver 161.

  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.

  FIG. 3 is an explanatory diagram showing the configuration of the image display device 8.

  The light source 501 includes a light emitting element 510, a polarizing filter 511, and a Fresnel lens 512. The light emitting element 510 is configured by using point light sources such as white light emitting diodes arranged side by side or linear light sources such as cold cathode tubes arranged horizontally. The polarizing filter 511 is set so that the light transmitted through the right region 511a and the left region 511b has different polarization (for example, the light transmitted through the right region 511a and the left region 511b is shifted by 90 degrees). The Fresnel lens 512 has a lens surface having concentric irregularities on one side.

  The light emitted from the light emitting element 510 is transmitted only by the polarization filter 511 with a certain polarization. That is, of the light emitted from the light emitting element 510, the light passing through the right region 511a of the polarizing filter 511 and the light passing through the left region 511b are irradiated to the Fresnel lens 512 as light of different polarizations. As will be described later, light that has passed through the right region 511a of the polarizing filter 511 reaches the left eye of the observer, and light that has passed through the left region 511b 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 512 from a different position.

  The light transmitted through the polarizing filter 511 is irradiated to the Fresnel lens 512. The Fresnel lens 512 is a convex lens, and the Fresnel lens 512 refracts the optical path of the light radiated from the light emitting element 510 substantially in parallel, passes through the fine retardation plate 502, and irradiates the liquid crystal display panel 504. .

  At this time, light emitted from the fine retardation plate 502 is emitted so as not to spread in the vertical direction, and is applied to the liquid crystal display panel 504. That is, light that has passed through a specific region of the fine retardation plate 502 is transmitted through a specific display unit portion of the liquid crystal display panel 504.

  In addition, among the light irradiated on the liquid crystal display panel 504, the light that has passed through the right region 511 a of the polarizing filter 511 and the light that has passed through the left region 511 b are incident on the Fresnel lens 512 at different angles. The liquid crystal is refracted and emitted from the liquid crystal display panel 504 through different paths.

  The liquid crystal display panel 504 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 502 and a polarizing plate 503 (second polarizing plate) are disposed on the light source 501 side of the liquid crystal display panel 504, and a polarizing plate 505 (first polarizing plate) is disposed on the viewer side. ing.

  In the fine phase difference plate 502, regions for changing the phase of transmitted light are repeatedly arranged at fine intervals. Specifically, the region 502 a where the half-wave plate 521 having a fine width is provided on the light-transmitting base material 522, and the same interval as the width of the half-wave plate 521, 1 / The region 502b where the two-wave plate 521 is not provided is repeatedly provided at a fine interval. That is, the region 502a that changes the phase of light transmitted by the provided half-wave plate 521 and the region 502b that does not change the phase of light transmitted because the half-wave plate 521 is not provided are fine. It is provided repeatedly at intervals. The half-wave plate 521 functions as a phase difference plate that changes the phase of transmitted light.

  The half-wave plate 521 is arranged so that its optical axis is inclined 45 degrees with respect to the polarization axis of the light transmitted through the right region 511a of the polarization filter 511, and the polarization axis of the light transmitted through the right region 511a is rotated by 90 degrees. And exit. That is, the polarization of the light transmitted through the right region 511a is rotated by 90 degrees so as to be equal to the polarization of the light transmitted through the left region 511b. That is, the region 502b in which the half-wave plate 521 is not provided transmits light having the same polarization as the polarizing plate 503 that has passed through the left region 511b, and the region 502a in which the half-wave plate 521 is provided. Light that has passed through the right region 511 a and whose polarization axis is orthogonal to the polarizing plate 503 is rotated so as to be equal to the polarizing axis of the polarizing plate 503 and is emitted.

  The repetition of the polarization characteristics of the fine retardation plate 502 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 504. To be different. Therefore, the polarization specification of the fine phase difference plate corresponding to each horizontal line (scanning line) of the display unit of the liquid crystal display panel 504 is different, and the direction of the emitted light is different for each horizontal line.

  Alternatively, the repetition of the polarization characteristics of the fine retardation plate 502 is performed at a pitch that is an integral multiple of the display unit pitch of the liquid crystal display panel 504 so that the polarization characteristics of the fine retardation plate 502 are changed for each of a plurality of display units (that is, 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 characteristics of the fine retardation plate are different for each of the plurality of horizontal lines (scanning lines) of the display unit of the liquid crystal display panel 504, 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 504 with different light every time the polarization characteristics of the fine retardation plate are repeated, the liquid crystal display panel 504 transmits through the fine retardation plate 502. It is necessary that the light radiated to suppress the diffusion in the vertical direction.

  That is, the region 502a in which the phase of the light on the fine retardation plate 502 is changed transmits the light transmitted through the right region 511a of the polarizing filter 511 with the same polarization as the light transmitted through the left region 511b. In addition, the region 502b of the fine retardation plate 502 where the phase of the light is not changed transmits the light transmitted through the left region 511b of the polarizing filter 511 as it is. The light emitted from the fine retardation plate 502 has the same polarization as the light transmitted through the left region 511b and enters the polarizing plate 503 provided on the light source side of the liquid crystal display panel 504.

  The polarizing plate 503 functions as a second polarizing plate and has a polarization characteristic that transmits light having the same polarization as the light transmitted through the fine retardation plate 502. That is, the light transmitted through the left region 511b of the polarizing filter 511 is transmitted through the second polarizing plate 503, and the light transmitted through the right region 511a of the polarizing filter 511 is rotated through the polarization axis by 90 degrees to pass through the second polarizing plate 503. To Penetrate. In addition, the polarizing plate 505 functions as a first polarizing plate and has a polarization characteristic of transmitting light having a polarization different from that of the polarizing plate 503 by 90 degrees.

  Such a fine retardation plate 502, a polarizing plate 503, and a polarizing plate 505 are bonded to a liquid crystal display panel 504, and the fine retardation plate 502, the polarizing plate 503, the liquid crystal display panel 504, and the polarizing plate 505 are combined to form an image display device. Configure. At this time, in a state where a voltage is applied to the liquid crystal, the light transmitted through the fine retardation plate 502 is transmitted through the polarizing plate 505. On the other hand, in a state where no voltage is applied to the liquid crystal, the light transmitted through the fine retardation plate 502 is emitted from the liquid crystal display panel 504 because the polarized light is twisted 90 degrees and is not transmitted through the polarizing plate 505.

  The diffuser 506 is attached to the front side (observer side) of the first polarizing plate 505 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.

  FIG. 4 is a plan view showing the optical system of the image display device 8.

  As shown in FIG. 4, the light emitted from the light emitting element 510 passes through the polarizing filter 511 and spreads radially. Of the light emitted from the light source, the light that has passed through the right region 511a of the polarizing filter 511 (the center of the optical path is indicated by a one-dot chain line) reaches the Fresnel lens 512, and the traveling direction of the light is changed by the Fresnel lens 512. The light passes through the fine retardation plate 502, the polarizing plate 503, the liquid crystal display panel 504, and the polarizing plate 505 substantially vertically (slightly from the right side to the left side) and reaches the left eye.

  On the other hand, of the light emitted from the light source, the light transmitted through the left region 511b of the polarizing filter 511 (the center of the optical path is indicated by a broken line) reaches the Fresnel lens 512, and the traveling direction of the light can be changed by the Fresnel lens 512. Thus, the light passes through the fine retardation plate 502, the polarizing plate 503, the liquid crystal display panel 504, and the polarizing plate 505 substantially vertically (slightly from the left side to the right side) and reaches the right eye.

  In this way, the light emitted from the light emitting element 510 and transmitted through the polarizing filter 511 is irradiated to the liquid crystal display panel 504 substantially perpendicularly by the Fresnel lens 512 as an optical means. That is, the light emitting element 510, the polarizing filter 511, and the Fresnel lens 512 constitute the light source 1 that irradiates the liquid crystal display panel 504 with light having different polarization planes substantially vertically and through different paths, and transmitted through the liquid crystal display panel 504. 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 504 and the repetition pitch of the polarization characteristics of the fine phase difference plate 502 are made equal, and light coming from different directions is irradiated for each scanning line pitch of the liquid crystal display panel 504 and is different. Light is emitted in the direction.

  The light radiated from the light emitting element 510 and transmitted through the right side region 511a of the polarizing filter is transmitted through the Fresnel lens 512, reaches the fine retardation plate 502, and is emitted after rotating the polarized light by 90 degrees (the right side region 511a is output). The light passes through the region 502a of the fine retardation plate 502 (which transmits the transmitted light), and further passes through the polarizing plate 503, the liquid crystal display panel 504, and the polarizing plate 505 to reach the left eye. That is, the left eye image displayed by the display element at a position corresponding to the region 502a of the liquid crystal display panel 504 reaches the left eye.

  Since the regions 502 b arranged alternately with the regions 502 a of the fine retardation plate 502 do not change the polarization of light, the light from the right region 511 a of the polarizing filter does not pass through the polarizing plate 503, and the liquid crystal display The right eye image displayed on the display element at the position corresponding to the region 502b of the panel 504 does not reach the left eye.

  On the other hand, the light emitted from the light emitting element 510 and transmitted through the left region 511b of the polarizing filter passes through the Fresnel lens 512, reaches the fine retardation plate 502, and the light of the same polarization in the left region 511b of the polarizing filter. The light passes through the region 502b of the fine retardation plate 502 that passes through, passes through the liquid crystal display panel 504 and the polarizing plate 505, and reaches the right eye. That is, the right eye image displayed by the display element at a position corresponding to the region 502b of the liquid crystal display panel 504 reaches the right eye.

  Since the regions 502 a arranged alternately with the regions 502 b of the fine retardation plate 502 change the polarization of light, the light from the left region 511 b of the polarizing filter does not pass through the polarizing plate 503, and the liquid crystal display The left eye image displayed on the display element at the position corresponding to the region 502a of the panel 504 does not reach the right eye.

  That is, the right-eye image and the left-eye image by the image display device 8 allow the observer to view as a stereoscopic image by three-dimensional perception based on binocular parallax.

  As described above, the image display apparatus using the fine phase difference plate has been described as an example of a method for obtaining a stereoscopically viewable three-dimensional image. However, a method using a lenticular lens, a parallax barrier method, and an imaging function of a concave mirror are used. The present invention can be applied as an effect in the relationship between a stereoscopically viewable three-dimensional image and an accessory as long as it can perceive a stereoscopic image such as a method.

  FIG. 5 is a front view of the center case 11 constituting the display window of the image display device 8 according to the embodiment of the present invention. FIG. 5 (a) shows a non-operating state of the stereoscopic assistant 60, and FIG. ) And (c) show the operating state of the stereoscopic assistant 60.

  The image display device 8 is attached to the back of the center case 11. An armor portion 41 that prevents the game ball from falling to the front area of the window portion 40 of the center case 11 is provided on the upper peripheral edge of the center case 11. A rod-like stereoscopic assistant 60 is attached to the head. The stereoscopic assistant 60 is attached to a rotating shaft 62 supported by the center case 11, and the rotating shaft 62 is connected to a motor as driving means (not shown) disposed at the back of the center case 11. The stereoscopic assistant 60 is made of a resin material having a light guide property, and an LED 34 is provided as a light emitting element in the stereoscopic assistant 60 or in the vicinity of the rotation shaft 62. The assistant 60 is caused to emit light.

  FIG. 5A shows a state in which the motor is stopped. In this state, the stereoscopic assistant 60 is stopped at the horizontal position and does not overlap the display area of the image display device 8.

  FIG. 5B shows a state in which the stereoscopic assistant 60 protrudes into the display area of the image display device 8 and reciprocates (rotates) on the display area due to normal rotation and reverse rotation of the motor.

  FIG. 5C shows a state in which the stereoscopic assistant 60 is rotated in one direction by driving the motor in one direction. The stereoscopic assistant 60 protrudes into the display area of the image display device 8 for approximately half a period and rotates on the display area.

  6 and 7 show an example of the operation of the stereoscopic assistant 60 when moving and displaying a stereoscopically viewable three-dimensional stereoscopic image. FIG. 6 is a view of the image display device 8 as seen from the front, and FIG. It is a figure showing a motion of an observer's eyes | visual_axis.

  6A and 7A, a three-dimensional stereoscopic image 3D (shown by a black circle in FIG. 7) appears on the right side of the display area of the image display device 8, and a stereoscopic view is displayed in the vicinity of the image 3D. FIG. 7 shows a state in which the assistant 60 (FIG. 7 shows the stereoscopic assistant tip portion indicated by a white circle) is driven. The three-dimensional stereoscopic image 3D is displayed so as to appear at a distance (protruded position) substantially the same as the distance to the stereoscopic assistant 60 with respect to the display screen of the image display device 8.

  6B, 7C, 7B, and 7C, the 3D stereoscopic image 3D is moved and displayed from the right side of the display area of the image display device 8 to the left side, and the 3D stereoscopic image 3D is displayed. The stereoscopic assistant 60 is moved from the right side to the left side of the display area of the image display device 8 at the same speed in synchronization with the moving display of the 3D stereoscopic image 3D.

  In this way, when a stereoscopically viewable 3D stereoscopic image is moved and displayed, the stereoscopic assistant 60 is driven in the vicinity of the 3D stereoscopic image so that the 3D stereoscopic image is displayed on the display screen of the image display device 8. By displaying so as to appear at approximately the same protruding position as the distance to the stereoscopic assistant 60, it is possible to display a reference for the appearance position of the three-dimensional stereoscopic image, and the state in the vicinity of the three-dimensional stereoscopic image By moving the stereoscopic assistant 60 at the same speed in synchronization with the moving display of the three-dimensional stereoscopic image, the stereoscopic assistant 60 can be used as a contrast object to assist the stereoscopic vision of the moving image. Thus, the observer can easily recognize the moving three-dimensional stereoscopic image.

  When the stereoscopic assistant 60 is a real object, the appearance position of the three-dimensional stereoscopic image can be easily perceived. In addition, by causing a 3D stereoscopic image to appear at a protruding position that is substantially the same as the distance to the stereoscopic assistant 60, the appearance position can be more easily perceived.

  For this reason, even if the moving speed of the 3D stereoscopic image is increased (for example, up to about 20 ° per second (viewing angle of viewpoint)), the observer can recognize the moving 3D stereoscopic image. The degree of freedom of rendering of the original stereoscopic image is increased, a rich 3D stereoscopic image can be realized, and the interest of the stereoscopic image can be further improved.

  On the other hand, the movement display of the three-dimensional stereoscopic image and the movement operation of the stereoscopic assistant 60 synchronized therewith may be repeated a plurality of times.

  When performing an effect of moving left and right with respect to the display area of the image display device 60 such as a character image, the stereoscopic assistant 60 operates in the same manner. In this way, it is easy to see a three-dimensional stereoscopic image of a character or the like, and a rich expression can be achieved.

  Further, when a 3D stereoscopic image appears outside the display area of the image display device 60, the stereoscopic vision of the 3D stereoscopic image is reproduced by repeating the operation of the stereoscopic assistant 60 in accordance with the moving display of the 3D stereoscopic image. Can assist.

  FIG. 8 shows the positional relationship between the three-dimensional stereoscopic image and the stereoscopic assistant 60.

  In the case of FIG. 8A, the three-dimensional stereoscopic image 3D is displayed at a position that does not overlap with the stereoscopic assistant 60 protruding in the display area of the image display device 8.

  In the case of FIG. 8B, the 3D stereoscopic image 3D is displayed at a position overlapping the stereoscopic assistant 60 on the near side (observer side) of the stereoscopic assistant 60 protruding into the display area of the image display device 8. ing.

  In the case of FIG. 8C, the 3D stereoscopic image 3 </ b> D is displayed at a position overlapping the stereoscopic assistant 60 on the back side of the stereoscopic assistant 60 protruding into the display area of the image display device 8.

  In the state where the 3D stereoscopic image and the stereoscopic assistant 60 are overlapped, the light from the display screen of the image display device 8 is blocked by the stereoscopic assistant 60. For example, when the 3D stereoscopic image is small, the observer views the image. In this case, the operation position of the stereoscopic assistant 60 is set so as not to block all the left and right eye images related to the three-dimensional stereoscopic image.

  That is, as shown in FIG. 8A, the stereoscopic assistant 60 is positioned close to the 3D stereoscopic image 3D, or overlapped with a part of the 3D stereoscopic image 3D as shown in FIGS. 8B and 8C. Is controlled.

  In this way, the stereoscopic assistant preferably functions as a contrast object for the depth perception of the three-dimensional stereoscopic image. In addition, since at least one of the left and right eyes or a part of the image is visible, stereoscopic recognition of the three-dimensional stereoscopic image is not impaired. In the case of FIGS. 8B and 8C, the 3D stereoscopic image is not stopped and moved, although a part of the 3D stereoscopic image is missing and recognized by the observer. In this case, the missing part of the three-dimensional stereoscopic image is complemented by the viewer's perception, so that it does not hinder stereoscopic vision.

  The stereoscopic assistant 60 is a rod-like one, but may be a mark, a character, a natural product imitation, or a variety of forms in which these are attached to the tip of a rod-like member. The size of the stereoscopic assistant 60 may be formed in advance smaller than that of the original stereoscopic image.

  9 and 10 show an example of the operation of the stereoscopic assistant 60 in a game (variable display game).

  When the variation display game is started, variation display of the left symbol, the middle symbol, and the right symbol is started in each of the left variation display region, the middle variation display region, and the right variation display region provided in the display region of the image display device 8. The Then, when the middle symbol is stereoscopically displayed (for example, the reach state in which the left symbol and the right symbol are aligned), the stereoscopic assistant 60 starts to operate in accordance with the variable display of the middle symbol (which stops last).

  Then, the stereoscopic assistant also performs a rotating operation in synchronism with the variable display so that the middle symbol i appears from the A position in a three-dimensional display state and disappears from the C position through the B position. . Then, in a state where the middle symbol is not displayed, the stereoscopic assistant goes from the C position to the A position through the D position. The same applies to the middle symbol j and the middle symbol k. Since the stereoscopic assistant operates in synchronization with the symbol variation display in this way, the depth perception of the symbol displayed in three dimensions is helped, and the sense of depth can be easily perceived and the stereoscopic effect can be richly felt. In addition, the stereoscopic assistant that operates periodically can easily predict the movement of the three-dimensionally displayed symbol, thereby helping to perceive stereoscopic vision.

  Note that the variable display of each symbol may be performed by scrolling the symbol from the top to the bottom of the display area, by the rotation of the symbol, or by switching the symbol where the next symbol appears after the symbol is reduced. Good. The stereoscopic assistant 60 is controlled so as to be rotated in one direction. However, the stereoscopic assistant 60 is not limited to this, and performs a reciprocating operation between A, B, and C, and a vibration operation in accordance with the temporary stop of the symbol. You may control.

  Further, the rotational speed of the stereoscopic assistant 60 may be controlled in correspondence with the changing speed of the middle symbol, and the angular speed is not limited to a constant value.

  Note that the variable display area need not be limited to left, middle, and right, and may be set to upper, middle, and lower, for example.

  In this way, it is possible to make the variable display pattern of the three-dimensional stereoscopic image easy to see, and to enhance the taste of the variable display game.

  FIG. 11 is a front view of the center case 11 constituting the display window of the image display device 8 according to another embodiment of the present invention, and shows another aspect of the stereoscopic assistant.

  In the image display device 8 shown in FIG. 11A, a stereoscopic assistant 70 (octopus character) is attached to the center case 11 at the lower part on the near side of the image display device 8. The stereoscopic assistant 70 can be moved up and down by driving an electric actuator (motor-driven ball screw cylinder) (not shown) connected to the stereoscopic assistant 70.

  That is, by driving the electric actuator in the advancing direction, the stereoscopic assistant 70 is driven upward from the center case 11 at the lower part of the image display device 8 and appears at a position overlapping the display area of the image display device 8. Further, by driving the electric actuator in the backward direction, the stereoscopic assistant 70 is lowered, and is hidden in the storage portion 71 provided in the center case 11 during concealment and does not overlap the display area of the image display device 8. It becomes.

  In the image display device 8 shown in FIG. 11B, a stereoscopic assistant 72 (jellyfish character) is attached to the center case 11 at the upper front side of the image display device 8. A non-illustrated lifter (motor-driven reel) is disposed on the body portion 73 (the jellyfish head) of the stereoscopic assistant 72, and a movable portion 74 (jellyfish foot) connected to the lifter by a winding line is driven by the lifter. It can move up and down.

  That is, by driving the lifter in the lowering direction, the movable portion 74 (the jellyfish's foot) is lowered (extends and moves) from the main body portion 73 (the jellyfish's head) and is positioned so as to overlap the display area of the image display device 8. Appear. Further, by driving the lifter in the winding direction, the movable part 74 (jellyfish legs) is driven upward (contracted), and when concealed, it is hidden in the main body part 73 (jellyfish head) to display an image. The display area of the device 8 is not overlapped.

  In the image display device 8 shown in FIG. 11C, stereoscopic assistants 75 a and 75 b (shark characters) are rotatably attached to the center cases 11 on both the left and right sides of the front side of the image display device 8.

  By driving a motor (not shown), the stereoscopic assistants 75a and 75b appear from the storage portions 76a and 76b on the left and right sides, and can move (swing) the display area of the image display device 8 up and down.

  By the forward rotation of the motor, the stereoscopic assistants 75a and 75b appear from the storage portions 76a and 76b on the left and right sides, and the display area of the image display device 8 is swung downward. By the reverse rotation of the motor, the stereoscopic assistants 75a and 75b are swung upward in the display area of the image display device 8, and are hidden in the storage portions 76a and 76b when concealing.

  FIG. 12 shows another aspect of the stereoscopic assistant.

  This is achieved by attaching an organic EL (electroluminescence) between the outer glass 18a and the inner glass 18b of the cover glass 18 as a front structural member for protecting the gaming area disposed on the front surface of the game board 6, and effect control. The stereoscopic assistant 80 is displayed on the organic EL by the device 150 or the decoration control device 250.

  The stereoscopic assistant 80 is displayed in the vicinity of a stereoscopically viewable 3D stereoscopic image by the image display device 8, and is moved and displayed in synchronization with the moving display of the 3D stereoscopic image.

  That is, in an image display device that displays a stereoscopically visible image by the parallax effect of the left and right eyes, the image display device includes a stereoscopic image display unit that displays a stereoscopically visible image and the front side of the stereoscopic image display unit. A stereoscopic assistant display device (organic EL or the like) that displays a stereoscopic assistant 80 that assists stereoscopic vision of the image, and when stereoscopically displaying images that can be stereoscopically viewed on the stereoscopic image display unit, An image display device comprising assistant control means (for example, a decoration control device 250) for controlling the assistant 80 to move and display in synchronization with the moving display of the stereoscopically viewable image.

It may be configured to start the movement or to move the stereoscopic assistant when starting the movement display of the stereoscopically visible image.

  According to the movement of the stereoscopic assistant triggered by the movement display of the stereoscopically visible image, the stereoscopic assistant is a contrast object of the stereoscopically visible image, so the depth perception given by the stereoscopic assistant depends on the stereoscopically visible image. Helps the depth perception of the presented stereoscopic image and enriches the stereoscopic effect obtained from the stereoscopic image. In addition, since the stereoscopically viewable image and the stereoscopic assistant move together, it is easy for the observer to grasp the relationship as the contrast object.

This makes it easier to understand the relationship. In addition, if the movement of the stereoscopic assistant follows or precedes the movement display of the stereoscopically viewable image, it becomes easier for the observer to grasp the relationship as the contrast object.

  If the stereoscopic assistant is moved to start moving and displaying the stereoscopically visible image, the movement of the stereoscopic assistant will be a movement advance notice of the stereoscopically visible image, and attention to the stereoscopic assistant will be preceded.
