The communication from the game control device 100 to the various dependent control devices (the display control device 150, the discharge control device 200, the decoration control device 250, and the sound control device 300) is performed in a unidirectional manner from the game control device 100 to the dependent control device. Only communication is allowed. Thereby, it is possible to prevent an illegal signal from being input from the slave control device side of the game control device 100.
[0048]
The display control device 150 constituting the display control means controls the display of an image, and functions as a display control means together with the composition conversion device 170. The display control device 150 stores a CPU 151, a VDC (Video Display Controller) 156, a RAM 153, an interface 155, a ROM 152 storing programs and the like, 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.
[0049]
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 composed of sprite data, polygon data, etc., background screen). Information, moving image object screen information, etc.) and instruct the VDC 156 to generate an image.
[0050]
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 of the image control information 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 (synthesis conversion device 170) at predetermined timing (vertical synchronization signal V_SYNC, horizontal synchronization signal H_SYNC).
[0051]
The drawing processing performed by the VDC 156 performs point drawing, line drawing, triangle drawing, and polygon drawing, and further performs texture mapping, alpha blending, shading processing (such as glow shading), and hidden surface removal (such as Z buffer processing) to perform γ correction. The image signal is output to the synthesis conversion device 170 via the circuit 159.
[0052]
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 (such as V_SYNC).
[0053]
Here, as the frame buffer, a plurality of frame buffers are respectively set in a predetermined storage area or the like of the RAM 153, and the VDC 156 can output the image by superimposing (overlaying) it on an arbitrary image.
[0054]
An oscillator 158 that supplies a clock signal is connected to the VDC 156. The clock signal generated by the oscillator 158 defines the operation cycle of the VDC 156. The VDC 156 divides the frequency of the clock signal to generate a vertical synchronizing signal (V_SYNC) and a horizontal synchronizing signal (H_SYNC), and output them to the synthesizing converter 170. At the same time, the VDC 156 outputs the vertical synchronizing signal (V_SYNC) and the horizontal synchronizing signal (H_SYNC) to the fluctuation display device 8 via the synthesizing converter 170.
[0055]
The RGB signals output from the VDC 156 are input to the gamma correction circuit 159. The γ correction circuit 159 corrects the non-linear characteristic of the illuminance with respect to the signal voltage of the variable display device 8, adjusts the display illuminance of the variable display device 8, and generates an RGB signal to be output to the variable display device 8. .
[0056]
Further, the CPU 151 of the display control device 150 identifies whether the image data (RGB) to be output to the combining conversion device 170 is a left-eye image or a right-eye image based on the clock signal of the oscillator 158. An L / R signal is output.
[0057]
Further, the CPU 151 controls the light emission amount (luminance) of the variable display device 8 based on the variable display state (for example, whether the display is a normal variable display game or a big hit display) or a game state. The control signal DTY_CTR is generated based on the clock signal of the oscillator 158, and is output to the variable display device 8.
[0058]
The synthesis conversion device 170 is provided with a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer. The right-eye image sent from the VDC 156 is written into the right-eye frame buffer, and the left-eye image is written into the left-eye frame buffer. Write to frame buffer. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, write the stereoscopic image frame buffer, and output the stereoscopic image data to the variable display device 8 as RGB signals.
[0059]
The generation of the stereoscopic image by synthesizing the right-eye image and the left-eye image is performed, as shown in FIG. 3, at every interval of the half-wave plate 821 attached to the micropole 802. Combine left-eye images. Specifically, since the half-wave plates 821 of the micropole 802 of the variable display device 8 of the present embodiment are arranged at intervals of the display unit of the liquid crystal display panel 804, the display unit of the liquid crystal display panel 804 The stereoscopic image is displayed such that the right-eye image and the left-eye image are alternately displayed for each horizontal line (scanning line).
[0060]
The left-eye image data transmitted from the VDC 156 during the L signal output is written to the left-eye frame buffer, and the right-eye image data transmitted from the VDC 156 during the R signal output is written to the right-eye frame buffer. Then, the image data for the left eye written in the frame buffer for the left eye and the image data for the right eye written in the frame buffer for the right eye are read out for each scanning line, and written in the frame buffer for stereoscopic vision.
[0061]
A liquid crystal driver (LCD DRV) 181 and a backlight driver (BL DRV) 182 are provided in the variable display device 8. A liquid crystal driver (LCD DRV) 181 applies a voltage sequentially to the electrodes of the liquid crystal display panel based on the V_SYNC signal, the H_SYNC signal, and the RGB signal sent from the synthesizing converter 170, and applies a voltage to the liquid crystal display panel 804 for stereoscopic viewing. The composite image of is displayed.
[0062]
The backlight driver 182 changes the duty ratio of the voltage applied to the light emitting element (backlight) 810 based on the DTY_CTR signal output from the CPU 151, and changes the brightness of the liquid crystal display panel 804.
[0063]
FIG. 3 is an explanatory diagram illustrating the configuration of the variable display device 8. 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 a point light source such as a white light emitting diode (LED) or by horizontally arranging a linear light source such as a cold cathode tube. The polarization filter 811 is set such that the polarization of light transmitted through the left region 811a and the polarization of light transmitted through the right region 811b are different (for example, the polarization of light transmitted through the left region 811a and the polarization of light transmitted through the right region 811b are shifted by 90 degrees). The Fresnel lens 812 has a lens surface having concentric unevenness on one side surface.
[0064]
As for the light emitted from the light emitting element 810, only light having a certain polarization is transmitted by the polarization filter 811. That is, of the light emitted from the light emitting element 810, the light that has passed through the left region 811a of the polarizing filter 811 and the light that has passed through the right region 811b are irradiated to the Fresnel lens 812 as light having different polarizations. As described below, light passing through the left region 811a of the polarizing filter 811 reaches the right eye of the observer, and light passing through the right region 811b reaches the left eye of the observer.
[0065]
Note that, without using a light-emitting element and a polarizing filter, it is sufficient to irradiate light of different polarizations from different positions.For example, two light-emitting elements that generate light of different polarizations are provided, and different polarizations are provided. Light may be applied to the Fresnel lens 812 from different positions.
[0066]
The light transmitted through the polarizing filter 811 is applied to the Fresnel lens 812. The Fresnel lens 812 is a convex lens, and the Fresnel lens 812 refracts the optical path of light emitted from the light emitting element 810 so as to be substantially parallel to the liquid crystal display panel 804 (micropole 802).
[0067]
At this time, the light applied to the liquid crystal display panel 804 is applied so as not to spread in the vertical direction, and is applied to the micropole 802 (first polarizing plate). That is, light transmitted through a certain region of the micropole is transmitted through a specific display unit of the liquid crystal display panel 804.
[0068]
Further, of the light applied to the liquid crystal display panel 804, the light passing through the right region 811a and the light passing through the left region 811b of the polarizing filter 811 enter the Fresnel lens 812 at different angles, and The light is refracted and radiated from the liquid crystal display panel 804 through different paths.
[0069]
In the liquid crystal display panel 804, a liquid crystal that is oriented by being twisted at a predetermined angle (for example, 90 degrees) is disposed between two transparent plates (for example, a glass plate). Make up. Light that has entered the liquid crystal display panel is emitted with the polarization of the incident light shifted by 90 degrees when no voltage is applied to the liquid crystal. On the other hand, in the state where a voltage is applied to the liquid crystal, the liquid crystal is untwisted, so that the incident light is radiated as it is.
[0070]
A micropole (first polarizing plate) 802 and a polarizing plate 803 (second polarizing plate) are arranged on the light source 1 side of the liquid crystal display panel 804, and a polarizing plate (second polarizing plate) is placed on the player (observer) side. A three-polarizing plate 805 is disposed.
[0071]
The micropole 802 functions as a first polarizing plate, and regions in which the polarization of transmitted light is different are repeatedly arranged at fine intervals. Specifically, the half-wave plate 821 having a fine width is attached to the polarizing plate 822 at the same minute interval as the width of the half-wave plate 821, and the half-wave plate 821 is attached. A region 802a where the 波長 wavelength plate 821 is not attached is repeatedly provided at a minute interval. The half-wave plate 821 is arranged such that its crystal axis is shifted by 45 degrees from the polarization of light transmitted through the right region 811a of the polarizing filter 811 and shifts the polarization of light transmitted through the right region 811a by 90 degrees in the crystal axis direction. Rotate and emit. That is, the polarization of the light transmitted through the right region 811a is shifted by 90 degrees to be equal to the polarization of the light transmitted through the left region 811b. The polarization plate 822 serving as the base material of the micropole 802 matches the polarization of light transmitted through the left region 811b of the polarization filter 811.
[0072]
The repetition of the polarization characteristics of the micropole 802 is performed at the same pitch as the display unit of the liquid crystal display panel 804 so 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 different. I do. Therefore, the polarization specification of the micropole corresponding to each horizontal line (scanning line) of the display unit of the liquid crystal display panel 804 is different, and the direction of the emitted light is different for each horizontal line.
[0073]
Alternatively, the repetition of the polarization characteristic of the micropole 802 is performed by setting the polarization characteristic of the micropole 802 for each of a plurality of display units (that is, the horizontal line of the plurality of display units) as a pitch of an integral multiple of the pitch of the display unit of the liquid crystal display panel 804. ), So that the polarization of the transmitted light is different for each of the plurality of display units. Therefore, the polarization of the micropole is different for each of a plurality of horizontal lines (scanning lines) of the display unit of the liquid crystal display panel 804, and the direction of light emitted for each of the plurality of horizontal lines is different.
[0074]
As described above, 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 micropole 802 is repeated, so that the light is transmitted to the liquid crystal display panel 804 through the micropole 802. It is necessary for the light to be diffused in the vertical direction.
[0075]
That is, the region 802a of the micropole 802 to which the half-wave plate 821 is attached transmits the light transmitted through the right region 811a of the polarizing filter 811 by changing the polarization of the light transmitted through the left region 811b. The region 802b of the micropole 802 to which the half-wave plate 821 is not attached transmits the light transmitted through the left region 811b of the polarizing filter 811. The light emitted from the micropole 802 has the same polarization as the light transmitted through the left region 811b, and is incident on a polarizing plate 803 (second polarizing plate) provided on the light source side of the liquid crystal display panel 804.
[0076]
The polarizing plate 803 functions as a second polarizing plate, has the same polarization characteristics as the polarizing plate 822 used as the base material of the micropole 802, and transmits light of the same polarization as light transmitted through the micropole 802. Polarization characteristics. Further, the polarizing plate 805 functions as a third polarizing plate, and has a polarization characteristic of transmitting light having a polarization that is different from the polarizing plate 803 by 90 degrees.
[0077]
The micropole 802, the polarizing plate 803, and the polarizing plate 805 are attached to a liquid crystal display panel 804, and an image display device is configured by combining the micropole 802, the polarizing plate 803, the liquid crystal display panel 804, and the polarizing plate 805. At this time, when a voltage is applied to the liquid crystal, light transmitted through the micropole 802 transmits through the polarizing plate 805. On the other hand, when no voltage is applied to the liquid crystal, the light transmitted through the micropole 802 is emitted from the liquid crystal display panel 804 with its polarization being twisted by 90 degrees, and thus does not transmit through the polarizing plate 805.
[0078]
Note that the polarization characteristics of the polarizing plate (second polarizing plate) 3 are equal to the polarizing characteristics of the polarizing plate 822 used as the base material of the micropole 802 (third polarizing plate), and light that can pass through the polarizing plate 803. Only the polarizing plate used as the base material of the micropole 802 transmits the polarizing plate used as the base material of the micropole 802. The light may enter the liquid crystal display panel 804.
[0079]
The diffuser 806 is attached to the front surface (on the observer side) of the third polarizing plate 805, and functions as a diffusion unit that vertically diffuses light transmitted through the liquid crystal display panel. Specifically, the light transmitted through the liquid crystal display panel is vertically diffused using a lenticular lens in which vertical and concave portions are repeatedly provided.
[0080]
FIG. 4 is a plan view showing an optical system of the variable display device 8.
[0081]
Light emitted from the light emitting element 810 is transmitted through the polarization filter 811 and spreads radially. Of the light emitted from the light source, the light that has passed through the left region 811a of the polarizing filter 811 reaches the Fresnel lens 812, the traveling direction of the light is changed by the Fresnel lens 812, and the micropole 802, the polarizing plate 803, and the liquid crystal. The light reaches the display panel 804 and the polarizing plate 805, passes through them substantially vertically (slightly from left to right), and reaches the right eye.
[0082]
On the other hand, of the light emitted from the light source, the light that has passed through the right region 811b of the polarizing filter 811 reaches the Fresnel lens 812, the traveling direction of the light is changed by the Fresnel lens 812, and the micropole 802, the polarizing plate 803 , The liquid crystal display panel 804 and the polarizing plate 805, which are transmitted substantially vertically (slightly from right to left) to reach the right eye.
[0083]
In this manner, the light emitted from the light emitting element 810 and transmitted through the polarizing filter 811 is applied to the liquid crystal display panel 804 almost vertically by the Fresnel lens 812 as an optical unit, and the light is emitted by the light emitting element 810, the polarizing filter 811 and the Fresnel lens 812. A light source 1 for irradiating the liquid crystal display panel 804 with light having different polarization planes substantially vertically and through different paths, and emitting light transmitted through the liquid crystal display panel 804 through different paths to reach the right eye or the left eye. Let it.
[0084]
FIG. 5 is an enlarged view of the light emitting element 810 and is a front view as viewed from the polarizing filter 811 side.
[0085]
The light emitting element 810 is composed of a plurality of white LEDs, and is divided into groups (systems) in which the timing of performing light emission control is synchronized. For example, when performing light emission control in two groups as shown in FIG. A white LED 810A (A in the figure) constituting one light-emitting group and a white LED 810B (B in the figure) constituting a second light-emitting group. These white LEDs 810A and 810B are alternately arranged in the left-right direction in the figure. The display device 8 is driven by the BL driver 182 under duty control.
[0086]
FIG. 6 shows an example of the timing of a signal sent from the display control device 150, and shows the relationship between the vertical synchronization signal V_SYNC shown in FIG. 2, the image data (DATA), and the duty control signal DTY_CTR.
[0087]
Here, in FIG. 6, the duty control signal DTY_CTR is divided into a duty signal LED_A for controlling the white LED 810A and a duty signal LED_B for controlling the white LED 810B, and each is generated by the CPU 151 of the display control device 150.
[0088]
In FIG. 6, when the vertical synchronization signal V_SYNC is set to V0, V1, V2, and V3 in order of elapse of time, the white LED 810A, which is the first light emitting group, is turned on at the rise of the vertical synchronization signal V0, while the second LED is lit. Are turned off. Note that the image data is output from the display control device 150 at the fall of the vertical synchronization signal.
[0089]
At the next rising edge of the vertical synchronization signal V1, the white LED 810A that is being lit is turned off, while the white LED 810B that has been turned off is turned on and lit. Thereafter, each time the vertical synchronization signal rises, the white LEDs 810A and 810B alternately light.
[0090]
Therefore, the two groups of white LEDs 810A and 810B are driven by the duty signals LED_A and LED_A 180 ° out of phase to maintain the brightness of the variable display device 8 having the liquid crystal display panel 804 while maintaining the life of the light source. Can be improved.
[0091]
Further, by synchronizing the blink timing of the white LEDs 810A and 810B with the vertical synchronization signal, the two groups of white LEDs 810A and 810B can be switched in synchronization with the refresh operation of the liquid crystal display panel 804 of the variable display device 8. , So that the player does not feel strange.
[0092]
Next, an example of light emission control performed by the display control device 150 according to a game state will be described with reference to FIGS. 7, 8, and 9. FIG.
[0093]
FIG. 7 is a state transition diagram of the game, FIG. 8 is a flowchart of light emission control performed by the display control device 150, and FIG. 9 is a table of light emission patterns according to light emission modes.
[0094]
FIG. 7 shows a flowchart of the game, and the outline of the game will be described below with reference to this figure.
[0095]
First, at the beginning of the game (or before the start of the game), the game is in a customer waiting state, and a signal for instructing display of a customer waiting screen is transmitted from the game control device 100 to the display control device 150, and the variable display device 4 is displayed. A customer waiting screen (moving image or still image) is displayed on the screen.
[0096]
Then, when a game ball hit in the game area of the game board 6 wins the starting port 16, a predetermined random number is extracted by the game control device 100 based on the winning, and a jackpot lottery of the variable display game is performed. Then, a signal for instructing variable display is transmitted from the game control device 100 to the display control device 150, and the variable display of a plurality of symbols is started in the left, right, and middle variable display areas of the screen of the variable display device 8.
[0097]
After a predetermined time elapses after the start of the fluctuation display, the fluctuation display is temporarily stopped in the order of, for example, left, right, and middle (for example, the symbol is slightly fluctuated at the stop position). When a state (for example, a combination in which the left symbol and the right symbol can generate a big hit combination) occurs, a predetermined reach game is performed. In this reach game, for example, the fluctuation display of the middle symbol is performed at an extremely low speed, the fluctuation is changed at a high speed, or the fluctuation display is reversed. In addition, background display and character display are performed according to the reach game.
[0098]
The temporary stop state is a state in which the player can recognize the symbol as a substantially stopped state, and the final stop mode is not determined. The stopped state includes the temporary stop state and the state in which the symbol is stopped. State. In addition, as a specific example of the temporary stop state, in addition to the minute fluctuation at the stop position, there are modes such as enlarging and reducing a symbol, changing the color of the symbol, and changing the shape of the symbol.
[0099]
If the result of the jackpot lottery is a jackpot, the symbols in the left, right, and middle are finally stopped in a predetermined combination of jackpots, and a jackpot game (a special game state advantageous to the player) occurs. When the big hit game occurs, a special game in which the variable winning device 10 is opened for a predetermined period is performed. This special game is executed with a predetermined number (for example, 10) of game balls or a predetermined time (e.g., 30 seconds) passed to the variable prize device 10 as one unit (one round). A prescribed round (for example, 16 rounds) is repeated on condition that a prize is won in the continuous winning opening (detection of a winning ball by the continuation sensor 16S). When a jackpot game occurs, a signal for instructing the display of the jackpot game to the display control device 150 is transmitted from the game control device 100 to the display control device 150, such as a jackpot fanfare display, a round number display, a jackpot effect display, and the like. A jackpot game is displayed on the screen.
[0100]
In this case, if the jackpot is a specific jackpot, a specific game state is generated after the jackpot game, and the probability of occurrence of the next jackpot is increased, or the fluctuation based on the winning of the game ball to the starting port 16 as described later. The fluctuation display time of the fluctuation display game on the display device 8 is shortened.
[0101]
When the game ball wins in the starting port 16 during the variable display game or the big hit game (when a special symbol start memory is generated), the variable hit game is ended after the variable display game is ended (at a loss) or the big hit game is ended. After that, a new variable display game is repeated based on the special symbol start memory. In addition, when the variable display game ends (at the time of loss) or when the big hit game ends, if there is no special symbol start memory, the game is returned to the customer waiting state.
[0102]
When a game ball passes through the ordinary symbol starting gates 27A and 27B, a random number related to the ordinary symbol is extracted based on the passing or the ordinary symbol starting memory, and if the random number is a hit, the hit symbol is displayed on the normal symbol display 7. As a result, the ordinary variable prize winning device 8 of the starting port 16 is expanded for a predetermined time, and prize winning in the starting port 16 is facilitated.
[0103]
FIG. 8 is a flowchart of light emission control performed by the CPU 151 of the display control device 150, which is executed at predetermined time intervals (for example, every 16.7 msec = 1/60 second equal to the generation cycle of the vertical synchronization signal). is there.
[0104]
First, in step S1, the control waits for the generation of an interrupt signal accompanying the rise of the vertical synchronization signal (V_SYNC). When the vertical synchronization signal rises, the process proceeds to step S2.
[0105]
In step S2, it is determined whether the display command signal received from the game control device 100 corresponds to the occurrence of the jackpot or the end of the jackpot. In this case, the process proceeds to step S4.
[0106]
In either case of occurrence of a jackpot or termination of the jackpot, the process proceeds to step S3 to switch the light emission mode.
[0107]
That is, when the signal for notifying the occurrence of the special game state is received, or when the signal for notifying the end of the special game state is generated, the light emission mode is switched.
[0108]
When a big hit occurs, the light emission mode 0 is switched from the normal light emission mode 0 to the light emission mode 1 at the time of the big hit, and when the big hit is ended, the light emission mode 1 at the time of the big hit is switched to the normal light emission mode 0.
[0109]
Here, as shown in the table of FIG. 9, the light emission mode indicates the relationship between the blinking pointer that is sequentially repeated from 0 to 3 every time a vertical synchronization signal is generated and the ON / OFF of the light emission group of the white LEDs 810A and 810B. It is determined.
[0110]
Thereafter, the blinking pointer is incremented by 1 in step S4, and in step S5, the white LEDs 810A and 810B are driven in the blinking state corresponding to the current light emission mode with reference to the table of FIG.
[0111]
Next, in step S6, the image data is output from the VDC 156 to the synthesizing converter 170, and in step S7, the drawing information of the next frame is calculated. Thus, the symbol is changed (that is, the drawing content is updated) in synchronization with the generation of the vertical synchronization signal.
[0112]
By repeating the above steps S1 to S7, the white LEDs 810A and 810B are driven at a duty ratio of 50% in the normal mode 0 as shown in FIG. The white LEDs 810A and 810B are alternately turned on every other vertical synchronization signal at a duty ratio of 25%, which is half the brightness of the normal light emission mode.
[0113]
That is, in the normal light emission mode 0, as shown in FIG. 6, the white LEDs 810A and 810B are alternately blinked at the rising edge of the vertical synchronization signal with the 50% duty signals LED_A and B of 180% different phases. The LCD panel 804 is illuminated with the brightness of.
[0114]
On the other hand, the light emission mode 1 at the time of the big hit is a duty signal LED_A, B of 25% (ON duty), in which the white LEDs 810A, B are blinked every other vertical synchronization signal. During a jackpot game in which attention is not paid, the brightness of the liquid crystal panel 804 is reduced to reduce power consumption and extend the life of the light emitting element 810.
[0115]
That is, as shown in FIG. 10, at the rising edge of the vertical synchronization signal V0 (blinking pointer = 0), the white LED 810A of the first light-emitting group is turned on to illuminate the liquid crystal panel 804, and the next vertical synchronization signal V1 ( At the rise of the blinking pointer = 1), the white LED 810A is turned off, and during the period of the vertical synchronization signals V1 and V2, both groups remain off.
[0116]
Next, the white LED 810B, which is the second light emitting group, is turned on at the rising of the vertical synchronization signal V2 (blinking pointer = 2), and the liquid crystal panel 804 is illuminated. The white LED 810B is turned off at the next rise of the vertical synchronization signal V3 (blinking pointer = 1), and both groups remain off during the period of the vertical synchronization signals V1 and V2.
[0117]
Thus, during the variable display game in which the player pays attention to the variable display device 8, the brightness of the light emitting element 810 is increased in the light emission mode 0 to provide a bright screen, while the player pays attention to the large winning opening of the variable winning device 10. During a jackpot game in which little attention is paid to the variable display device 8, the brightness of the light-emitting element 810 is reduced as the light emission mode 1, and the liquid crystal panel is set according to the degree of attention of the player to the variable display device 8 according to a change in the game state. By changing the driving pattern (luminance) of the light emitting element 810 included in the backlight 804, reduction in power consumption and heat generation and extension of the life of the light emitting element 810 can be realized.
[0118]
Further, the blinking timings of the white LEDs 810A and 810B of the two groups are synchronized with the vertical synchronization signal that defines the refresh operation of the liquid crystal panel 804, so that it is not necessary to configure a circuit for generating a new signal, and the light emission is not performed. The driving circuit of the element 810 can be simply configured, and an increase in manufacturing cost can be prevented.
[0119]
Further, since the plurality of white LEDs 810A and 810B are switched in synchronization with the vertical synchronization signal, the control of the brightness of the backlight (light emitting element 810) can be made to correspond to the speed of the symbol change of the variable display device 8. Since it is possible to prevent the player from feeling uncomfortable, and by synchronizing the switching of the light emission mode with the vertical synchronization signal, it is possible to prevent the occurrence of color unevenness of the liquid crystal panel 804, and to switch the brightness. It can be realized without giving a strange feeling to the person.
[0120]
Further, since the plurality of white LEDs 810A and 810B are alternately turned on, the temperature rise of each of the white LEDs 810A and 810B can be suppressed and the life of the light emitting element 810 can be extended as compared with the case where the white LEDs 810A and 810B are always turned on. And the reliability of the gaming machine can be improved.
[0121]
Further, since the brightness of the variable display device 8 changes according to the game state, the degree of appeal of the information provided by the variable display device 8 to the player can be increased, and the brightness can be changed to an appropriate brightness according to the game state. It is possible to improve interest in the variable display device 8.
[0122]
Further, in the display control device 150, since the oscillator 158 that generates the reference clock is formed of a crystal oscillator, an oscillator, or the like, it is possible to prevent the flashing timing of the light emitting element 810 from being shifted due to individual differences in gaming machines. An adjustment process such as brightness adjustment of the light-emitting element 810 is not required, and manufacturing cost can be reduced.
[0123]
In addition, since a white LED is employed as the light emitting element 810, heat generation can be suppressed while securing a large amount of light, and drive control can be performed by direct current, so that the configuration of the drive circuit can be simplified. .
[0124]
Further, the liquid crystal panel 804 of the variable display device 8 displays the image for the left eye and the image for the right eye, respectively, so that the player can enjoy the variable display game while experiencing a three-dimensional image. And the brightness of the backlight corresponding to the display of the stereoscopic image can be changed by changing the light emission mode as described above.
[0125]
FIG. 11 shows a second embodiment, in which the light emitting element 810 of the first embodiment is divided into four light emitting groups, and a first light emitting group including a plurality of white LEDs 810A, and the same number of white LEDs 810B. The second light emitting group is composed of a plurality of white LEDs 810C, the third light emitting group is composed of a plurality of white LEDs 810D, and the fourth light emitting group is also composed of a plurality of white LEDs 810D. , 810B, 810C, and 810D are set to the same number.
[0126]
Each light emitting group is arranged substantially in a line, and is repeatedly arranged in the order of 810A, 810B, 810C, and 810D from the left in the figure. Note that the number of white LEDs in each row may be different, and it is only necessary that the total number of white LEDs be set the same in each light emitting group.
[0127]
These four light emitting groups are driven based on a duty signal from the CPU 151 of the display control device 150 in FIG. 2, and the duty signal is a duty signal LED_A for driving the first light emitting group, as shown in FIG. The duty signal LED_B drives the second light emitting group, the duty signal LED_C drives the third light emitting group, and the duty signal LED_D drives the fourth light emitting group.
[0128]
The ON / OFF switching of the duty signals LED_A to D_D is performed in synchronization with the vertical synchronization signal V_sync, as in the first embodiment. For example, three light emitting groups are always lit, and any one of the light emitting groups Is turned off.
[0129]
That is, in FIG. 12, the duty signal LED_A is turned on at the rise of the vertical synchronization signal V0, and the white LED 810A is turned on, while the duty signal LED_B is turned off and the white LED 810B is turned off, but the duty signals LED_C and D are turned on. Therefore, in the period of the vertical synchronization signals V0 to V1, the three light emitting groups of the white LEDs 810A, 810A, 810D are lit.
[0130]
Next, when the vertical synchronization signal V1 rises, the duty signals LED_A and D maintain the ON state, the duty signal LED_B switches from OFF to ON, the lighting of the white LED 810B resumes, and the duty signal LED_C changes from ON to OFF. And the white LED 810C is turned off.
[0131]
In this way, in the large number of white LEDs 810A to 810D, three light emitting groups are turned on at the same time, while the other light emitting group is turned off for one cycle of the vertical synchronizing signal. Since the switching is performed every three periods, the light emitting groups are prevented from being constantly lit, the heat generation is suppressed, and the life is extended. It can be enhanced.
[0132]
As described above, the plurality of light-emitting groups are configured with the same number of white LEDs, and the constant number of white LEDs are constantly turned on, thereby preventing the occurrence of color unevenness and the like on the liquid crystal panel 804, and giving a sense of incongruity to the player. Light emission control can be performed.
[0133]
As shown in FIG. 13, the arrangement of the white LEDs may be such that a plurality of white LEDs are linearly arranged to form a linear light source, and each light emitting group (810A to 810D) may be configured for each line. In this case, it is desirable that the arrangement direction of each group be arranged along the horizontal direction of the polarizing filter 811, the milescropole 802, the liquid crystal panel 804, and the like shown in FIGS.
[0134]
Further, when there is a large variation in the brightness of each light emitting group due to a manufacturing error of the white LED or the like, the number of white LEDs constituting each light emitting group may be increased or decreased to make the brightness of each light emitting group uniform.
FIG. 14 shows a third embodiment, in which the light emitting element 810 of the first embodiment blinks white LEDs 810A and 810B alternately in synchronization with a horizontal synchronization signal H_SYNC. This is the same as in the first embodiment.
[0135]
Assuming that the horizontal synchronization signal H_SYNC is, for example, 33.3 KHz, ON-OFF is repeated at a cycle of 30 μs, and the white LED 810A, which is the first light emitting group, is turned on at the rise of the horizontal synchronization signal H0 in the figure to light up. On the other hand, the white LED 810B as the second light emitting group is turned off.
[0136]
Next, the horizontal synchronization signals H1, H2, H, etc. are sequentially generated, and when the number of horizontal synchronization signals reaches a preset value, for example, 32 (clock), the white LED 810A that is lit at the rising edge of the horizontal synchronization signal H32. Is turned off, while the white LED 810B, which has been turned off, is turned on and turned on. Thereafter, the white LEDs 810A and 810B are alternately turned on every 32 clocks of the horizontal synchronization signal.
[0137]
Accordingly, the white LEDs 810A and 810B of the two groups are driven by the duty signals LED_A and LED_A shifted by 180 ° every predetermined clock, and the brightness of the variable display device 8 having the liquid crystal display panel 804 is kept constant. The life of the light source can be improved.
[0138]
Further, by synchronizing the blink timing of the white LEDs 810A and 810B with a predetermined clock of the horizontal synchronization signal H_SYNC (or a predetermined cycle synchronized with the horizontal synchronization signal H_SYNC), the drawing operation of the liquid crystal display panel 804 of the variable display device 8 is performed. Since the two groups of white LEDs 810A and 810B can be switched in synchronization, the player does not feel uncomfortable.
[0139]
