The display procedure data storage unit 14 stores display procedure data describing designation of a symbol used for generating the display image data Dg, designation of a time for displaying the display image G, designation of a display size of the display image G, and the like. Ds and an operation program of the display control unit 12 are stored. The VRAM 15 stores display image data Dg generated by the display control unit 12 virtually drawing an image. The design data storage unit 16 corresponds to a storage unit in the present invention, and stores various design data Dp (data such as the ground, Mt. Fuji, numerals, a lamp design, a background, and fireworks to be described later) for generating the display image data Dg. Remember. In this case, the design of the game image Gy and the lamp image Gl can be easily changed by changing the display procedure data Ds and the design data Dp.
[0033]
Next, the overall operation of the pachinko machine 1 will be described with reference to the drawings.
[0034]
In the pachinko machine 1, when the power is turned on, first, the main control unit 3 first issues, for example, a command C1 for displaying the game image Gy shown in FIG. A command C2 for displaying a decorative image Gd composed of lamp images Gl, Gl... Of low brightness (blue) and, for example, a white background image Gg is output. In response, the display control unit 12 executes the image display processing 40 shown in FIG. In the image display processing 40, first, the display control unit 12 checks the content of the command C1 (step 41). Next, the display control unit 12 reads the display procedure data Ds specified in the command C1 from the display procedure data storage unit 14 (Step 42), and specifies the image content to be displayed. Next, the display control unit 12 reads, from the symbol data storage unit 16, each symbol data Dp necessary for generating the gaming image data Dy for displaying the gaming image Gy (Step 43). Subsequently, the display control unit 12 generates game image data Dy based on the read design data Dp (step 44). At this time, the display control unit 12 virtually draws the game image Gy corresponding to the game image data Dy on the virtual plane Wy of the VRAM 15 shown at the upper left of FIG. 5 (stores it in the VRAM 15). The game image data Dy is generated in the VRAM 15.
[0035]
Next, the display control unit 12 checks the content of the command C2 (step 45). Next, the display control unit 12 reads the display procedure data Ds specified in the command C2 from the display procedure data storage unit 14 (Step 46), and specifies the image content to be displayed. Subsequently, the display control unit 12 transmits the design data Dp (in this example, the data of the dark blue lamp design and the data of the white background) required for generating the decoration image data Dd for displaying the decoration image Gd. ) Is read from the symbol data storage unit 16 (step 47). Next, the display control unit 12 generates decoration image data Dd based on the read design data Dp (step 48). At this time, the display control unit 12 displays the decoration image Gd (dark blue lamp image G1, Gl... And white background image Gg) corresponding to the decoration image data Dd on the VRAM 15 shown in the upper right of FIG. The image data Dd for decoration is generated in the VRAM 15 by virtually drawing (stored in the VRAM 15) on the virtual plane Wd.
[0036]
In this case, each dark blue lamp image Gl is virtually drawn at a position corresponding to each hole 21h in the light shielding panel 21c, as shown in the upper right of FIG. Further, each lamp image Gl is virtually drawn such that the size when formed on the screen film 32 is slightly larger than each corresponding hole 21h of the light shielding panel 21c. Subsequently, the display control unit 12 combines the game image data Dy and the decoration image data Dd to generate display image data Dg (step 49). At this time, the display control unit 12 displays a display image G obtained by synthesizing the game image Gy corresponding to the game image data Dy and the decoration image Gd corresponding to the decoration image data Dd as shown in the lower part of FIG. The display image data Dg is generated in the VRAM 15 by virtually drawing (stored in the VRAM 15) on the plane Wg. Next, the display control unit 12 outputs the display image data Dg stored in the VRAM 15 to the projector unit 31 (Step 50). Thereafter, the display control unit 12 repeats steps 41 to 50 until new commands C1 and C2 are output.
[0037]
On the other hand, the projector unit 31 emits projection light L for displaying the display image G based on the output display image data Dg. Next, the emitted projection light L is reflected by the mirror 33, converted into parallel light by the Fresnel lens 34, and projected on the screen film 32. As a result, the display image G is formed on the screen film 32, the game image Gy is displayed on the game section 21a of the game board 21 as shown in FIG. 1, and the dark blue lamp image Gl is displayed on the frame 21b. It is displayed on the image display section 21d. In this case, the background image Gg is shielded by the light-shielding panel 21c, and the projection light L collected by the condenser lens 35 is projected on the screen film 32 and visually recognized as if the actual blue lamp is turned off. You.
[0038]
Next, when the game starts and the hit ball wins the start chucker 23, the main control unit 3 executes a lottery. At this time, the main control unit 3 outputs a command C1 for displaying a game image Gy representing a lottery state including an image in which numbers 1 to 9 are scrolled and a board design such as Mt. Fuji and the earth. A command C2 for displaying a decorative image Gd composed of a blue lamp image Gl, Gl... And a white background image Gg in place of the dark blue lamp image G1, Gl. I do. In response, the display control unit 12 outputs the image data for display Dg by executing the image display processing 40 described above. Next, when the projector unit 31 emits the projection light L, the gaming image Gy representing the lottery state is displayed on the gaming section 21a, and the blue lamp images Gl, Gl,... Are displayed on the frame 21b. It is displayed on the section 21d. At this time, the condenser lens 35 condenses a part of the projection light L and projects it on the screen film 32. Therefore, since the projection light L projected on a wide range is projected on a narrow range, the blue lamp images Gl, Gl ... are displayed brightly and visually recognized as if a real blue lamp is emitting light. You.
[0039]
Subsequently, when a reach occurs during the execution of the lottery, for example, the main control unit 3 sets the first and third digits shown in FIG. 6 to “7” and gradually reduces the speed to the second digit. A command C1 for displaying a game image Gy indicating a reach state including an image composed of three-digit numbers that scroll while scrolling and a board design such as Mt. Fuji and the earth, and blue lamp images G1, G1,. And outputs a command C2 for displaying a decorative image Gd composed of yellow lamp images Gl, Gl ... and a white background image Gg. In response, the display control unit 12 executes the image display processing 40 to output the display image data Dg. Next, when the projector unit 31 emits the projection light L, the game image Gy indicating the reach state is displayed on the game unit 21a as shown in FIG. 3 and the yellow lamp images Gl, Gl. Is displayed on the image display section 21d of the frame section 21b.
[0040]
Next, when a jackpot occurs as a result of the lottery, the main control unit 3 represents, for example, a jackpot state including an image in which the number “777” shown in FIG. 7 is stopped and a board pattern on which fireworks are launched. A command C1 for displaying the game image Gy, and a decoration image Gd in which the red lamp images Gl, Gl ... and the dark red lamp images Gl, Gl ... switch at predetermined time intervals are displayed. Command C2 is output. In response, the display control unit 12 executes the image display processing 40 to output the display image data Dg, and the projector unit 31 emits the projection light L. Thereby, as shown in the figure, the game image Gy representing the big hit state is displayed on the game section 21a, and the lamp images Gl, Gl ... are displayed on the image display section 21d of the frame section 21b. In this case, since the red lamp image Gl and the dark red lamp image Gl are switched at predetermined time intervals, it is displayed as if the actual red lamp is blinking. For this reason, the occurrence of the big hit is reliably notified to the player in combination with the gaming image Gy representing the big hit state.
[0041]
As described above, according to the pachinko machine 1, the display control unit 12 causes the projector unit 31 to display the game image Gy on the game unit 21 a of the game board 21, and displays the decoration image on the frame 21 b of the game board 21. By displaying Gd, the frame portion 21b of the game board 21 can be decorated with the decoration image Gd without using a decoration lamp, so that the decoration lamp and its wiring can be eliminated. Further, the decoration content can be changed only by changing the color of the lamp image Gl, for example. For this reason, the decoration content of the frame part 21b can be changed easily and cheaply. Further, since the color of the decoration image Gd and its change can be freely changed, the frame portion 21b can be variously decorated.
[0042]
Further, by displaying the lamp image Gl, it is possible to produce an effect in the same manner as a real decorative lamp. Further, the display control unit 12 switches the decorative images Gd having different hues and lightnesses of the lamp images Gl at a predetermined timing and displays them on the projector unit 31 so that, for example, when a big hit occurs, a so-called probability variation state And at the time of so-called special reach, by changing the color of the lamp image Gl to blue or red and displaying the same, the decoration of the frame portion 21b can be changed. The game can be continued without causing it. In addition, the display control unit 12 switches and displays the decoration image Gd having the different hue and brightness of the lamp image Gl at the time of the change of the game state on the pachinko machine 1, for example, a change in the game state such as occurrence of a big hit. By changing the color of the lamp image Gl or performing blinking display according to the above, it is possible to reliably notify the player of the change in the game state.
[0043]
In addition, the display control unit 12 generates the decoration image data Dd based on the design data Dp of the lamp design created for each hue, brightness, and shape, for example, so that the size is determined using one design data Dp. Display image data Dg for displaying a plurality of different lamp images Gl. For this reason, many types of lamp images Gl can be generated with less symbol data Dp. Furthermore, since the condenser lens 35 capable of condensing the projection light L is provided, the lamp image Gl can be displayed brightly, so that the effect can be enhanced. Further, by displaying the lamp image Gl on the image display unit 21d partitioned by the shielding unit 21e capable of shielding the projection light L, the boundary between the lamp image Gl and the background image Gg is shielded to clearly define the outline thereof. Since it can be visually recognized, an effect closer to a real decorative lamp can be performed.
[0044]
Note that the present invention is not limited to the above embodiment of the present invention. For example, instead of the decoration image Gd composed of the white background image Gg and the lamp image Gl, a decoration image Gd composed of the dark background image Gg and the lamp image Gl can be displayed. In this case, since the background image Gg is dark, the same effect as when the background image Gg is shielded by the light shielding panel 21c can be obtained. Therefore, the light shielding panel 21c can be made unnecessary. According to this configuration, the position and size of the lamp image Gl can be freely changed, so that the frame portion 21b can be more variously decorated. In addition, the lamp image Gl is not limited to dark blue, blue, yellow, dark red, and red, and can employ a lamp image Gl of various hues, brightness, and saturation.
[0045]
Further, the size and shape of the lamp image Gl can be changed and displayed. In this case, for example, a special effect can be performed by displaying a circular lamp image Gl that gradually increases or a lamp image Gl whose shape changes from elliptical to circular. Further, instead of the lamp image Gl, an image of a pattern imitating the shape of a character, an animal, a plant, a person, or the like can be adopted. In this case, these symbols can be freely displayed by replacing the holes 21h with light-shielding panels 21c formed in accordance with these shapes. Further, the game state change time points in the present invention include various game state change time points such as a so-called “probable change” occurrence time point and an end time point.
[0046]
【The invention's effect】
As described above, according to the display method, the display device for the gaming machine, and the gaming machine according to the present invention, the gaming image is displayed on the gaming section of the gaming board, and the decorative image is displayed on the frame portion of the gaming board. This makes it possible to decorate the frame with the decorative image, so that the decorative lamp and its wiring can be eliminated. Also, the contents of the decoration can be changed only by changing the decoration image. For this reason, the decoration of the frame portion can be changed easily and cheaply. Further, since the decorative image can be freely designed, the frame portion can be variously decorated. In addition, by displaying a decoration image including a design representing a lamp, it is possible to produce effects in the same manner as a real decoration lamp. Further, by switching at a predetermined timing the decorative image in which at least one of the parameters including the hue, lightness, saturation, shape, and size of the symbol representing the lamp is different, for example, when a jackpot occurs, a so-called probability fluctuation state At the time of so-called special reach, for example, by changing the color of the symbol representing the lamp to blue or red and displaying it, it is possible to cause a change in the decoration of the frame portion, so that the player is bored with The game can be continued without causing the game.
[0047]
Further, by changing and displaying the decoration image in which one or more of each parameter is different with the change timing of the gaming state in the gaming machine as a predetermined timing, it is possible to reliably notify the player of the change in the gaming state. Further, by generating the decoration image based on the design data of the design representing the lamp created for each hue, lightness, saturation and shape, it is possible to generate a variety of decoration images with less design data. . Furthermore, by projecting the projection light toward the condensing means capable of condensing the projection light on the back of the frame portion and displaying the decorative image, the design representing the lamp can be displayed brightly. Can be increased. Further, by displaying the decorative image on the image display section of the frame portion formed with a shielding section capable of shielding the projection light and an image display section partitioned by the shielding section and capable of displaying the decorative image, the lamp is provided. Can be shielded by clearly observing the boundary between the symbol representing the symbol and the background image surrounding the symbol, so that an effect closer to a real decorative lamp can be performed.
