) Is detected, and a detection signal is output to the main control board 3. The gate passage detector (gate switch) 13 a detects that a game ball has passed through the gate port 13, and outputs a gate passage signal as a detection signal to the main control board 3.

Control of the gaming operation by the main control board 3 is performed, for example, by the main CPU 3a executing a control program (hereinafter referred to as “main control program”). The main control program generates a random number on the software, and acquires a random number value (a jackpot determination random number value) in response to a start winning (referred to as “big hit lottery” in the present embodiment). Then, the main control program determines whether or not the acquired random value matches the jackpot random value at the jackpot determination timing described later (referred to as “determination” in the present embodiment),
If it is determined that the two random numbers match, it is determined as “big hit”, whereas if it is determined that they do not match, it is determined as “out”. Here, the big hit determination timing refers to the time when the special symbol variation display based on the start winning is started after the start winning.

The main control program starts the special symbol variation display by the special symbol display device 41 after the start winning is made in this way, and when the predetermined variation time has elapsed, the special symbol is displayed according to the jackpot lottery result. A stop symbol is displayed on the display device 41. In addition, the above "big hit"

The sub-control program executes a lottery (hereinafter referred to as “effect lottery”) as to what effect pattern should be controlled according to the lottery result obtained from the analysis result of the command and the variation time. Specifically, the sub-control program manages an effect control scheduler, and this effect control scheduler executes for each lottery result (depending on whether it is a “hit” or “out”). Multiple production patterns to be managed are managed. Furthermore, this production control scheduler includes a plurality of production patterns having different lengths of variation time even if the lottery results are the same. Moreover, even if the same lottery result and the variation time are the same, there are a plurality of effect patterns having different effect contents. In this way, the sub-control program executes the effect lottery to select the effect pattern corresponding to the lottery result and the variation time while referring to the effect control scheduler.

After executing such an effect lottery, the sub-control program outputs sound from the speakers 29a and 29b according to the effect pattern over the varying time, or lights the panel decoration lamp 36 in a predetermined color via the lamp relay board 32. The lamp relay board 34
The frame decoration lamp 31 is turned on or off with a predetermined color.

In addition, the sub-control program also selects an effect display pattern related to the variable display by the decorative symbol display devices 16 and 26, corresponding to the selected effect pattern. After the selection of the effect display pattern, the sub control program loads the decorative design control board 3 from the sub control board 35.

The display scheduler data is data including information for specifying material image data such as information relating to the configuration of the video to be displayed and sprite data necessary for rendering each scene constituting the video to be displayed.

The symbol CPU 311 operates based on the display control program stored in the control ROM 301, and instructs the VDP 330 to perform video display processing in order to realize video display based on the display scheduler data stored in the control ROM 301. A command list including a plurality of commands is generated and transferred to the VDP 330 by DMA (Direct Memory Access).

The control ROM 301 stores a plurality of display scheduler data corresponding to various video displays. Therefore, the design CPU 311 specifies the content of the video display to be displayed by the effect display command transferred from the command interface 303, reads out the display scheduler data corresponding to the specified video display content from the control ROM 301,
A command list is generated so that video display based on the read display scheduler data is realized.

The SDRAM 302 is a storage area used for temporarily storing a command list generated by the symbol CPU 311 and temporarily storing various data.

The VDP 330 functions as a video display processor for displaying video on the decorative symbol display devices 16 and 26 by sequentially executing a plurality of commands included in the command list transferred from the symbol CPU 311. Based on the command list transferred from the design CPU 311, the VDP 330 reads material image data such as sprite data corresponding to the video to be displayed from the source ROM 340 and decompresses it to draw each scene constituting the video. Various image displays are realized by transmitting the generated drawing data to the decorative symbol display devices 16 and 26 via the scalers 341 and 342.

In the present embodiment, one VDP 3 is provided for the two decorative symbol display devices 16 and 26.
Only 30 are provided. The VDP 330 includes two decorative symbol display devices 16, 2
6 generates a combined image obtained by spatially combining two images to be displayed in one frame, and outputs the generated combined image to the scalers 341 and 342 in common. And
The decorative symbol display devices 16 and 26 each display an image for the display device based on the composite image generated by the VDP 330.

Details of a specific method in which the two decorative symbol display devices 16 and 26 display images for their own devices based on the composite image generated by the VDP 330 will be described later.

(3-1-1. Configuration example of VDP330)
Next, the configuration of the VDP 330 for displaying images on the decorative symbol display devices 16 and 26 will be described with reference to FIG.

As shown in FIG. 4, the VDP 330 includes a CPU I / F (interface) 331,
Data transfer circuit 332, bus I / F (interface) 333, decompression circuit (decoder)
334, a drawing circuit 335, a data storage memory 336, a frame buffer memory 337, and a display circuit 338.

The CPU interface (I / F) 331 receives the command list transferred from the symbol CPU 311.

The data storage memory 336 is a so-called VRAM (Video RAM), and functions as a volatile video memory for developing various material image data necessary for drawing processing such as sprite data and moving image data.

The data transfer circuit 332 is based on the command list transmitted from the symbol CPU 311 via the CPU interface 331, and the sprite data necessary for video display to be displayed.
Source image data such as moving image data is sent to the source ROM 34 via the bus interface 333.
The data is read from 0 and expanded in the data storage memory 336 (material image data expansion means). Here, the decompression process includes not only the process of decompressing and storing the material image data stored in compression, but also storing the uncompressed material image data in the memory as it is. Shall be included.

Since the sprite data is stored in the source ROM 340 in a state where the data structure is compressed by a reversible compression method, the source RO via the bus interface 333 is used.
The sprite data read from the M340 is decoded (expanded) by the expansion circuit 334 and then stored in the data storage memory 336.

The frame buffer memory 337 is realized by a VRAM like the data storage memory 336, and has a configuration capable of temporarily storing the video data drawn by the drawing circuit 335 in a volatile manner. Note that the frame buffer memory 337 can draw and store video data for two frames. While the video data for one frame has been drawn and stored by the drawing circuit 335, the frame buffer memory 337 has already drawn. The data of the frame for which the drawing process has been completed can be displayed on the decorative symbol display devices 16 and 26 via the display circuit 338.

The drawing circuit 335 performs drawing processing using material image data such as sprite data and moving image data stored in the data storage memory 336 based on the command list from the symbol CPU 311 received by the CPU interface 331. Then, video data is generated for each frame constituting the video to be displayed and stored in the frame buffer memory 337.

The display circuit 338 is a synchronizing signal (V blank signal etc.) to the decorative symbol display devices 16 and 26.
And a video signal based on the image data generated in the frame buffer area of the frame buffer memory 337 while synchronizing with the synchronization signal.
, 342 to the decorative symbol display devices 16, 26. Further, the display circuit 338 includes an enlargement unit 339 for enlarging an output image. The enlargement unit 339 enlarges the image data stored in the frame buffer memory 337 at a preset magnification. Note that when the magnification in the enlargement unit 339 is less than 1, the output image is reduced and output, so the enlargement unit 339 is provided with a reduction function as well as an image enlargement function.

In the present embodiment, the case where the data storage memory 336 for storing the various material image data read from the source ROM 340 in a volatile manner is provided in the VDP 330 will be described. It is not limited to such a configuration. For example, the present invention is similarly applied to a gaming machine having a configuration in which a volatile video memory for volatile storage of various material image data read from the source ROM 340 is provided outside the VDP 330. It is possible to apply. In this way, the data storage memory 336 is stored in the VD.
In the case of a configuration provided outside the P330, the data storage memory 336 and the SDRAM 302
Can be configured by the same volatile video memory.

(3-1-2. Configuration Example of Scalers 341 and 342)
Next, the configuration of the scalers 341 and 342 for performing processing such as image clipping processing and enlargement / reduction processing on the drawing data generated by the VDP 330 will be described with reference to FIG.

As shown in FIG. 5, the scaler 341 includes a cutout unit 351 and a frame memory 35.
2 and an enlarged portion 353. The scaler 342 includes a cutout unit 361, a frame memory 362, and an enlargement unit 363. Here, the frame memory 3
52 and 362 will be described using a configuration in which the scalers 341 and 342 are provided, but the frame memories 352 and 362 can be obtained by externally attaching a memory outside the scalers 341 and 342.
In some cases, the configuration is realized. As described above, by externally attaching the memory outside the scalers 341 and 342, the storage capacity of the frame memories 352 and 362 is not unnecessarily large, and can be minimized according to the size of image data to be stored. Hardware cost can be reduced. In addition, it can be applied to image data of various image sizes, and versatility of image data that can be handled is improved.

The cutout unit 351 generates a symbol CPU 311 from the composite image generated by the VDP 330.
The image in the area set via serial communication is cut out from the frame memory 352
To store. The enlarging unit 353 performs a process of enlarging or reducing the image data stored in the frame memory 352 at an enlargement rate set by the symbol CPU 311, and applies it to the decorative symbol display device 16 provided correspondingly. Output.

Cutout unit 361, frame memory 362, and enlargement unit 363 in scaler 342
Since the operations of are the same as the operations of the cutout unit 351, the frame memory 352, and the enlargement unit 353 in the scaler 341, the description thereof is omitted. However, the image data processed by the enlargement unit 363 is output to the decorative symbol display device 26.

(3-2. Memory space of control ROM 301)
Next, the memory space of the control ROM 301 described above will be described.
As shown in FIG. 6, the control ROM 301 stores a display control program 401 for controlling the operation of the symbol CPU 311 and display scheduler data 402. The display scheduler data 402 includes information for specifying material image data such as sprite data necessary for drawing each scene constituting the video to be displayed and information regarding the configuration of the video to be displayed.

(3-2-1. Configuration Example of Display Scheduler Data 402)
When a plurality of characters are displayed in one frame, display scheduler data is provided for each character. Therefore, the display scheduler data 402 includes a plurality of display scheduler data 402 provided for each character as shown in FIG.

The display scheduler data 402a for a certain character is as shown in FIG.
Frame number 501, character number 502, X coordinate 503, Y coordinate 504, base point position 505, X direction enlargement factor 506, Y direction enlargement factor 507, and transparency (blend rate)
508 and information of rotation angle 509 are included. Display scheduler data 402
Since the configurations of b to 402f are the same as the display scheduler data 402a, the description thereof is omitted.

A frame number 501 indicates to which frame the display scheduler data 402a is displayed. A character number 502 indicates a number for identifying sprite data to be used from among a plurality of sprite data. X-coordinate 503 and Y-coordinate 504 indicate the position where the sprite image is displayed on the display screen. The base point position 505 indicates the location of the base point when designating the display position of the sprite image. The X direction enlargement factor 506 and the Y direction enlargement factor 507 indicate how much the sprite image is enlarged (or reduced) in the X direction and the Y direction, respectively. For example, in the range of 0 to 511%. It can be set. The transparency 508 is a value that specifies how much the sprite image is to be displayed when the sprite image is displayed over the background image. For example, the transparency 508 can be specified within a range of 0 to 100%. ing. A rotation angle 509 is a value for designating an angle for displaying a sprite image.

Here, the display scheduler data 402 is not prepared for all frames, but the display scheduler data 402 is prepared only for a specific frame, and the video for the intermediate frame is displayed as a prepared display. The data is interpolated and drawn with reference to the scheduler data 402.

(3-3. Memory space of source ROM 340)
Next, the memory space of the source ROM 340 described above will be described.
As shown in FIG. 8, the source ROM 340 displays sprite data 601 for displaying a sprite image generated in advance for displaying a specific video, palette data 602 for specifying a color, and a background image. Various material image data such as moving image data 603 is stored. Note that it is also possible to directly specify a color without using the palette data 602.

(4. Example of operation of gaming machine 1)
Next, the operation of the gaming machine 1 will be described with reference to the drawings.

(4-1. Game control processing)
Here, on the main control board 3, a main control program for controlling the progress of the game is operating, and the main control program acquires a random number for determining a big hit (a big hit lottery) triggered by a start winning prize. When there is a start win, the main control program compares the acquired jackpot determination random number value with a predetermined hit value at the jackpot determination timing based on the start win, and executes the jackpot determination. At the same time, if there is such a start-up prize, the main control program then continues the blinking state (special symbol variation display state) by the special symbol display device 41 for the variation time determined by lottery separately, and then the big hit Depending on the results of the lottery and determination, the special symbol display device 41 is turned on or off (displayed state of the stopped symbols).

When such a big hit determination is executed, the main control board 3 sends an effect command including information on the result of the big hit determination and the variation time determined by the lottery in parallel with the control of the special symbol display device 41. Output for. In the sub control board 35 that has received the effect command, an effect lottery is further executed, and an effect pattern corresponding to the result of the effect lottery is selected. This effect pattern is a pattern for outputting sound or light. Further, on the sub-control board 35, an effect display pattern corresponding to this effect pattern is selected.

This effect display pattern represents a pattern related to which effect display operation should be executed among a plurality of prepared effect display operations over a variable time, and includes information corresponding to each scene to be displayed as the effect display operation. .

Then, the sub control board 35 transmits an effect display command indicating an effect display to be displayed on the decorative symbol display device 16 to the decorative symbol control board 30 based on the selected effect display pattern.

  (5. Example of operation of decorative design display board 30)

(5-1. Reset start processing)
First, reset start processing (initialization processing based on reset) in the decorative design control board 30 will be described with reference to FIG. This reset start process is sequentially executed when the decorative symbol control board 30 is reset by an external reset signal or when a new power is turned on, or when an instantaneous power failure occurs during operation. An example is shown.

Here, the reset is executed not only in the hardware reset generated by an external circuit such as a reset circuit or a watchdog timer, but also in the software when a power-off is detected, as well as a power-on reset at power-on. Soft reset is also included.

When power is turned on or a momentary power failure occurs and a reset occurs, first, the decorative symbol display board 30 executes initialization processing of various hardware such as communication ports (step S10).

(5-1-1. Hot / cold determination processing)
Then, after the initialization processing of various hardware is executed, the following hot / cold determination processing is executed. In this hot / cold determination process, when a reset occurs or when power is restored from a power outage (when power is restored)
Alternatively, it is determined whether the hot start described later should be performed.

The hot / cold determination process will be specifically described below. In this embodiment, S
Of the data stored in the DRAM 302, data used for hot / cold determination is referred to as determination data. The symbol CPU 311 has a function of calculating a sum value regarding the determination data of the SDRAM 302 and holding it in another area of the SDRAM 302. In the present embodiment, the sum value held in this way is referred to as a “predetermined sum value”.

In this hot / cold determination process, first, a sum value is calculated for determination data stored in a specific area of the SDRAM 302, and a sum determination is executed (step S20). Here, in the present embodiment, calculating the sum value with respect to the determination data to be processed is referred to as “sum determination”. Next, the symbol CPU 311 compares the sum value calculated from the determination data stored in the specific area of the SDRAM 302 with a predetermined sum value, and determines whether or not both sum values are equal to each other. Is confirmed (step S30). By determining the thumb value in this way, the symbol CPU 311 determines whether or not the determination data stored in the specific area of the SDRAM 302 is normal without being destroyed at the time of power recovery (determination means). )
.

As a result of the sum determination, if the two sum values match, it is assumed that data other than the determination data stored in the SDRAM 302 is not destroyed, and the pattern CP
U311 sets the activation mode to “hot start” (step S40) and starts the operation (referred to as “hot start” in this embodiment). On the other hand, if the two sum values do not match as a result of the sum determination, it is assumed that the determination data is destroyed, and the symbol CPU 311 selects only the area in the SDRAM 302 where the determination data is stored. All other storage areas are cleared to 0 and initialized (step S50). "
“Clear 0” means initialization by filling “0” in the target storage area.

The symbol CPU 311 then sets the start mode to “cold start” (step S
60) All the data are set from the beginning and the operation is started. In this embodiment, at power recovery,
The design CPU 311 thus setting data from the beginning and starting the operation is called “cold start”.

The hot / cold determination process as described above is executed when the power is restored.
If the determination data is reliable, the data stored in the entire memory space of the SDRAM 302 including the area where the determination data is stored can be trusted (for example, there is no defect such as missing data). It is assumed that the game state before the power failure can be continued even after power recovery by continuously using the data in the memory space.

Here, even when a power failure state is detected, the data content stored in the RAM may not be destroyed. Generally, the voltage required for the RAM to maintain the memory state is the power failure state. This is because it is lower than the threshold voltage for detection.

(5-2. Example of operation of symbol CPU 311)
Next, an operation example when the decorative symbol display board 30 receives the effect display command from the sub-control board 35 after the reset start process as described above will be described.

The effect display command from the sub-control board 35 is received by the command interface 303 of the decorative design control board 30 and transferred to the design CPU 311 for processing. This design C
The operation of the PU 311 is shown in the flowchart of FIG.

When receiving the effect display command from the sub control board 35 (step S101), the symbol CPU 311 reads display scheduler data 402 corresponding to the effect display pattern specified by the effect display command from the control ROM 301 (step S102).

Then, the symbol CPU 311 generates a command list to be transmitted to the VDP 330 based on the display scheduler data 402 read from the control ROM 301 (
Step S103).

Next, the symbol CPU 311 repeats generation of a command list for drawing each sprite image until generation of a command list for all sprite images in one frame is completed, and generation of a command list for all sprite images is performed. When finished (
In step S104, the generated command list is transmitted to the VDP 330 (step S1).

First, the overall operation of the VDP 330 will be described with reference to the flowchart of FIG.

The VDP 330 receives a command list from the symbol CPU 311 and stores this command list in the data storage memory 336 (step S301). Then, based on the received command list, the data transfer circuit 332 reads various material image data such as sprite data and moving image data necessary for video display from the source ROM 340 (step S).
302).

The material image data such as sprite data transferred from the source ROM 340 is decoded by the decompression circuit 334 and then stored in the data storage memory 336 (step S303).

The drawing circuit 335 performs drawing processing using the material image data stored in the data storage memory 336 based on each command included in the command list received from the symbol CPU 311, and the generated image data is stored in the frame buffer memory. Sequentially stored in 337 (
Step S304).

Finally, the display circuit 338 converts the image data for one frame stored in the frame buffer memory 337 into a video signal, and outputs the video signal to the decorative symbol display devices 16 and 26 via the scalers 341 and 342 (step S305). ).

By performing the display process as shown in FIG. 11 for each frame, the VDP 33
0 can display the video composed of continuous display of each scene on the decorative symbol display devices 16 and 26 based on the command list transferred from the symbol CPU 311.

As shown in FIG. 12B, the horizontal width is 400 dots and the vertical length is 240 dots.
As described above, the decorative symbol display device 16 and the decorative symbol display device 26 have different image sizes.

In the present invention, the image size does not indicate the physical size of the image displayed on the decorative symbol display devices 16 and 26, but indicates the size based on the decorative symbol display devices 16 and 26 or the number of pixels constituting the image. ing. That is, in the present invention, the same image size means that the number of pixels in the vertical direction (number of dots) and the number of pixels in the horizontal width of the image are the same.

In general, even when data having the same number of pixels is displayed, the physical size of the finally displayed image varies depending on the resolution of the decorative symbol display devices 16 and 26 expressed by DPI (Dot Per Inch) or the like. Resulting in. However, for the VDP 330, the decorative symbol display devices 16, 26 are used.
Regardless of the physical size, the VDP 330 renders an image based only on the number of pixels in the vertical and horizontal directions in the decorative symbol display devices 16 and 26.

In the gaming machine of the present embodiment, the VDP 330 generates a composite image that spatially combines two images to be displayed on the two decorative symbol display devices 16 and 26, and the decorative symbol display devices 16 and 26. Then, based on the composite image generated by the VDP 330, the image for the own device is displayed. Therefore, according to this embodiment, the decorative symbol display device 16
, 26 can be displayed by one VDP 330 even if their sizes are different.

Further, in the second specific example described above, as shown in FIG.
6, the composite image that is included outside the displayable area of the decorative symbol display device 16 is displayed without cutting out the image B ′ to be displayed on the decorative symbol display device 26. Therefore, in the second specific example, as compared with the first specific example, it is not necessary to cut out the image for the decorative symbol display device 16 from the composite image, and the scaler 341 can be omitted. as a result,
The circuit configuration is simplified and the cost can be reduced.

Further, in the third specific example described above, as shown in FIG. 19, in the VDP 330, two images to be displayed on the decorative symbol display devices 16 and 26 are displayed at the same reduction ratio (1
/1.6), and is composed by spatially synthesizing within one frame, and when output, it is multiplied by 1.6 by the enlargement unit 339 and then output to the decorative symbol display device 16 and the scaler 342. Yes. Therefore, the decorative symbol display devices 16 and 26 need only display their own images based on the enlarged composite image. That is, only the image enlargement process is performed in the enlargement unit 339 of the VDP 330, and the scaler 342 does not need to execute the image enlargement process.

In general, the image enlargement function of the scalers 341 and 342 has higher performance than the image enlargement function of the VDP 330. However, if the image enlargement process is performed only by the enlargement unit 339 of the VDP 330 as in the third specific example, a gaming machine that is advantageous in terms of cost can be obtained by using a scaler that does not have an image enlargement function. Can be realized.

(8. Reference to other embodiments)
In the above-described embodiment, the case where the present invention is applied to the gaming machine including the two decorative symbol display devices 16 and 26 has been described. However, the present invention is not limited to such a case. The present invention can also be applied to a gaming machine provided with the above display device. For example, one VDP
When generating a composite image obtained by spatially combining three images to be displayed on the three display devices, a composite image as shown in FIG. 22 is drawn and output. In the image shown in FIG. 22, images A, B, and C for three display devices having different sizes are used.
Are synthesized spatially. A method in which each display device displays an image for its own device based on such a composite image can be realized by a method similar to the specific example shown in the above embodiment.

In this way, even when three or more display devices are provided in a gaming machine and at least one display device is different in size from other display devices, according to the present invention, a plurality of display devices can be displayed by one VDP. An image can be displayed on the apparatus.

Moreover, although the said embodiment demonstrated the case where this invention was applied with respect to the pachinko machine to which a game state transfers according to the internal lottery result performed with the winning to the starting winning opening of a game ball as a trigger, The present invention is not limited to such an embodiment. The present invention is similarly applied to other pachinko machines such as a pachinko machine having a pair of left and right movable pieces (a so-called “wings”) that opens and closes when a game ball is won at the start opening. It is possible to apply to.

Furthermore, the present invention is similarly applied to a gaming machine such as a revolving type gaming machine (slot machine) that uses medals or coins as a gaming medium as long as it is a gaming machine having a display device for displaying an effect operation. It is possible to apply. In addition, as an aspect of the spinning type game machine to which the present invention can be applied, the game medium is not limited to a medal or a coin, but may be an aspect using a game ball for a pachinko machine or the like.

In the above embodiment, display means (decorative symbol display device or the like) that performs a display operation using a liquid crystal element is illustrated. However, the present invention is not limited to this, and EL (electroluminescence: Elec) is used.
(tro Luminescence) element or display means using plasma may be applied.

In addition, in the said embodiment, although the decoration design control board 30 is controlling the production | presentation operation | movement which concerns on a display, it is not restricted to this, For example, the sub control board 35 only produces other production | presentation operations other than the presentation operation | movement concerning a display. Instead, a form having the function of the decorative design control board 30 may be employed.
