Next, a processing procedure for executing the present invention will be described with reference to FIGS. Here, a case where animation is displayed as one of continuous displays will be described. 6, FIG. 8, FIG. 11, FIG. 12, and FIG. 15 are flowcharts showing the processing procedure for carrying out the present invention. These processing procedures are all performed in the ROM 22 shown in FIG.
The processing program stored in the CPU 4 is executed by the CPU 230. These processing procedures embody the image processing means 50, and are executed every certain period (for example, 1 millisecond). In the figure, the number following S indicates a step number.

The animation process shown in FIG. 6 shows a processing procedure in the case where one symbol is displayed on the entire screen and this display is continuously performed for different symbols. First, scenario data stored in the ROM 224 shown in FIG. 5 is read according to the scenario data included in the control data (step S10). Here, the scenario data will be described with reference to FIG. FIG. 7 is four block diagrams showing an example of the configuration of scenario data. 7, the scenario data 500 shown in FIG. 7A includes a plurality of symbol numbers 504, 506,.
, 50m, and the number of symbol numbers (that is, the number of elements) is indicated by a screen number 502. That is, the screen number 502 stores the number of symbols to be displayed continuously. Here, the symbol number is a unique number assigned to each symbol. The scenario data shown in FIG. 7 is configured with the same number of elements, but may be configured with an arbitrary number of elements for each scenario data. That is, each data structure is configured corresponding to the optimum number of symbols for continuous display like animation, and the number of symbols is stored in the number of screens.

Further, the scenario data 510 shown in FIG. 7B includes a music number 514 and a plurality of elements 51.
, 51m, the number of elements including the music number 514 is 51 screens.
2 is a data structure indicated by 2; As is apparent from the figure, the difference from the scenario data 500 is that the music number 514 is added as an element parameter. This music number 5
Reference numeral 14 denotes a number for designating a music program stored in the music processing circuit 222 and for playing music as BGM in accordance with the music program. Music number 5 specified in this way
14, the BGM that is optimal for the animation flows along with the display of the animation. Therefore, in addition to the pleasure of seeing the special symbol display device 122, the player can also enjoy the enjoyment of listening to BGM.

Further, the scenario data 520 shown in FIG. 7C includes a plurality of elements 524, 526,.
This is a data structure composed of 52 m and indicating the number of these elements as the number of screens 522. The element 524 includes a symbol number 524a and a display period 524b, and the element 526 includes a symbol number 526.
a and a display period 526b. Similarly, the element 52m has a symbol number 52ma and a display period 5
It consists of 2mb. The display period is a period (time interval) during which the symbol designated by the symbol number is displayed on the special symbol display device 122. By designating this display period, it is not necessary to repeatedly designate the same pattern (same picture). Therefore, the program amount (data amount) required for the animation display process can be suppressed.

In the scenario data described above, the music number and the display period, which are element parameters, are configured as separate data structures, but may be configured as a data structure including elements obtained by combining these parameters. That is, scenario data consisting of a data structure having a plurality of such elements with [design number, music number, display period] as one element corresponds. In other words, it is a data structure in which the music number 514 is added to the number of screens 522 in the scenario data 520 of FIG. With this data structure, BGM can be played while changing the display period of one screen. Further, in the scenario data 510 and 520, a data structure may be configured with a pattern number described later as an element instead of the symbol number. Similarly, [
The pattern number, music number, and display period] may be one element, and a data structure including a plurality of these elements may be configured. By specifying a pattern number instead of a pattern number, an animation is displayed while displaying a complicated screen (picture) on one screen.
(Heavyness of the picture) is further improved.

Furthermore, the reading of scenario data in step S10 is not limited to the configuration in which scenario data having the scenario number corresponding to the progress of the game is selected and read, but the scenario number corresponding to the probability switched by the probability switching means 30 is read. You may comprise so that scenario data may be selected and read. The probability switching means 30 is means for switching the probability of realizing a gaming state that gives a special benefit to the player (that is, the probability of “big hit”) at an appropriate time, such as in the case of “big hit”. is there. Since the scenario data is read according to the probability switched by the probability switching means 30, animation is displayed in different scenarios even in the same gaming state, so the player keeps looking at the special symbol display device 122. I will never get bored.

Similarly, the scenario data read in step S10 includes the type of music by music number, the length of a period in which one screen is continuously displayed according to the display period, the symbol number, You may comprise so that the picture (symbol) displayed by a pattern number may be switched in various ways. Here, as the level of profit of the above-mentioned ball game machine, for example, in the ball game machine (pachinko game machine), when the game ball B wins a prize at the starting point for starting the special symbol display device 122, it is special after that. When the symbol displayed on the symbol display device 122 matches a predetermined symbol and becomes a “hit”, the game ball B is in a special area (winning slot 132 shown in FIG. 2).
When the prize was won, the crime prevention unit 306 received an abnormal signal output from the normal electric accessory solenoid 160, the big prize opening solenoid 166, the prize ball breakage detection switch 336, the prize ball payout prohibition switch 322, the frame detection switch 326, etc. There is a level of profit in each state such as time.

As described above, by setting optimal scenario data according to the gaming state and probability, various animations can be displayed on the screen of the special symbol display device 122. By displaying such animation, in addition to the pleasure of winning the game ball, the player is given the pleasure of watching the special symbol display device 122. Therefore, it is possible to keep the player interested without getting bored.

Returning to FIG. 6, when the music number is specified in the scenario data read in step S10, this music number is sent to the music processing circuit 222, and the BG corresponding to the music number is sent.
M is flowed (step S12). Then, according to the symbol number specified in the scenario data,
Corresponding symbol data is read from the ROM 224 and transferred to the frame memory 232 (step S14), and waits until the display period designated for the symbol transferred to the frame memory 232 elapses (step S16). Steps S14 and S16 are repeated by the number of elements specified by the scenario data (step S18). Through these steps S14 to S16, the special symbol display device 122 displays an animation according to the scenario data.

Next, a processing procedure when a plurality of symbols are combined and displayed on one screen and an animation is displayed will be described. In the animation process shown in FIG. 8, first, scenario data stored in the ROM 224 shown in FIG. 5 is read in accordance with the scenario data included in the control data (step S20), and a music number is designated in the read scenario data. If it is, the music number is sent to the music processing circuit 222, and the BGM corresponding to the music number is played (step S22). These steps are the same as steps S10 and S12 shown in FIG.

Here, an example of the scenario data read in step S20 is shown in FIG. Scenario data 530 shown in FIG. 7D includes a plurality of elements 534, 536,..., 53m.
Is a data structure indicating the number of these elements as the number of screens 532. Element 53
4 includes a symbol number 534a and a pattern number 534b, and an element 536 includes a symbol number 536a.
In the same manner, the element 53m includes a symbol number 53ma and a pattern number 53mb. Here, the pattern number is a unique number assigned to each combination pattern. This combination pattern is a data structure that designates a combination of a plurality of symbols, and will be described in detail later. By specifying this pattern number, a complex picture can be displayed on a single screen, such as a three-dimensional screen or a deep screen, increasing the fun of the animation display (heavyness of the picture). be able to.

Then, the combination pattern stored in the ROM 224 shown in FIG. 5 is read according to the pattern number included in the scenario data read in step S20 (step S24). Here, the combination pattern will be described with reference to FIGS. 9 and 10. 9 and 10 are block diagrams showing nine examples of the configuration of the combination pattern.

First, the combination pattern shown in FIG. 9 will be described. The combination pattern 600 shown in FIG. 9 (A) is a data structure composed of a plurality of symbol numbers 604, 606,..., 60n, and indicating the number of symbol numbers (that is, the number of elements) by the frame number 602. . That is, the frame number 602 stores the number of symbols to be synthesized and displayed. The combination patterns shown in FIG. 9 are all configured with the same number of elements, but may be configured with an arbitrary number of elements for each combination pattern. That is, each data structure is configured corresponding to the number of symbols optimally combined with the special symbol display device 122 and displayed on one screen, and the number of symbols is stored in the number of frames.

Further, a combination pattern 610 shown in FIG. 9B includes a plurality of elements 614, 616,.

The element 614 is composed of a symbol number 614a and a color number 614b, the element 616 is composed of a symbol number 616a and a color number 616b, and the element 61n is similarly composed of a symbol number 61na and a color number 61nb. The color number is a unique number assigned to each color according to the number of colors that can be developed by the special symbol display device 122. For example, “0” for black, “1” for blue
, Red ("2"), purple ("3", etc.).

Further, the combination pattern 620 illustrated in FIG. 9C includes a plurality of elements 624, 626,
.., 62n, a data structure indicating the number of these elements as the number of frames 622. The element 624 includes a symbol number 624a and a vector value 624b, the element 626 includes a symbol number 626a and a vector value 626b, and so on.
And the vector value 62nb. In the vector value, a direction for moving the symbol and a moving amount (for example, the number of dots) are designated. For example, when moving a symbol in the upper right (45 degrees) direction of the special symbol display device 122, a vector value [x = 1, y = 1] may be specified.
Similarly, when the symbol is not moved (displayed at a fixed position), the vector value [x = 0,
y = 0] may be specified.

The combination pattern 630 illustrated in FIG. 9D includes a plurality of elements 634, 636, and
.., 63n, a data structure indicating the number of these elements as the number of frames 632. The element 634 is composed of a symbol number 634a and a priority order 634b, the element 636 is composed of a symbol number 636a and a priority order 636b, and the element 63n is similarly composed of a symbol number 63na and a priority order 63nb. In the priority order, the frame position from the front side when the symbols are combined and displayed is designated. That is, the symbol corresponding to the symbol number is transferred to the frame corresponding to the priority order on a one-to-one basis, synthesized, and displayed. For example, when the numerical value “0” has the highest priority and the priority becomes lower as the position increases, the numerical value “
The symbol designated “0” is displayed on the most foreground surface, and is displayed on the background surface as the value increases.

Here, when a symbol has already been transferred to a frame corresponding to the priority order, the already transferred symbol is continuously displayed as it is unless the above-mentioned priority is designated by a new combination pattern. For example, if a symbol (number “7”) is transferred to the previous priority order x (frame number x), and if x is not specified for the priority order of the combination pattern to be specified thereafter, the symbol (number) transferred last time “7”) continues to be displayed.

Then, the combination pattern 640 illustrated in FIG. 9E includes a plurality of elements 644 and 646.
,..., 64n, and a data structure indicating the number of these elements as the number of frames 642. The element 644 is composed of a symbol number 644a and a coordinate value 644b, the element 646 is composed of a symbol number 646a and a coordinate value 646b, and the element 64n is similarly composed of a symbol number 64na and a coordinate value 64nb. In the coordinate value, the transfer start position in the frame for transferring the symbol is designated. The reason why the coordinate values are provided in this way is that the size of the symbol to be displayed may not match the size of the frame. That is, if a symbol having a size that does not match the size of the frame is transferred to the frame as it is, it is displayed at an unintended position on the screen. Therefore, by designating the position on the screen with the coordinate value, symbols of various sizes can be displayed at the desired position.

Next, the combination pattern shown in FIG. 10 will be described. A combination pattern 650 shown in FIG. 10 (F) is a data structure including a plurality of elements 654, 656,..., 65n, and indicating the number of these elements as the number of frames 652. Element 654 is symbol number 654
a and a rotation value 654b, the element 656 includes a symbol number 656a and a rotation value 656b, and similarly, the element 65n includes a symbol number 65na and a rotation value 65nb. As the rotation value, the symbol specified by the symbol number is rotated (for example, counterclockwise).
And the rotation angle.

A combination pattern 660 shown in FIG. 10G includes a plurality of elements 664, 666,.
This is a data structure composed of 6n and indicating the number of these elements as the number of frames 662.
The element 664 is composed of a symbol number 664a and a scroll value 664b, the element 666 is composed of a symbol number 666a and a scroll value 666b, and the element 66n is similarly composed of a symbol number 66na and a scroll value 66nb. In the scroll value, a movement amount (for example, the number of dots to be moved upward in the screen) for designating the symbol in a predetermined direction on the screen of the special symbol display device 122 is designated.

The combination pattern 670 shown in FIG. 10H includes a plurality of elements 674, 676,.
7n is a data structure showing the number of these elements as the number of frames 672.
The element 674 includes a symbol number 674a and a display period 674b, and the element 676 includes a symbol number 67.
6a and a display period 676b. Similarly, the element 67n includes a symbol number 67na and a display period 67nb. The display period is a period (time interval) during which the symbol designated by the symbol number is displayed on the special symbol display device 122. By designating this display period, it is possible to stop displaying symbols within the display period designated by the scenario data.

The combination pattern 680 shown in FIG. 10I includes a plurality of elements 684, 686,.
This is a data structure composed of 8n and indicating the number of these elements as the number of frames 682.
An element 684 is composed of a symbol number 684a and an enlargement / reduction value 684b, and an element 686 is a symbol number 6
86a and an enlargement / reduction value 686b. Similarly, the element 68n is made up of a symbol number 68na and an enlargement / reduction value 68nb. The enlargement / reduction value specifies the enlargement / reduction center position (coordinates) and magnification in order to enlarge (or reduce) the design designated by the design number. For example, if the symbol corresponding to the combination pattern in which the magnification of the enlargement / reduction value is “1” is used as the background and the symbol corresponding to the combination pattern that sequentially changes the enlargement / reduction value is used as the foreground, the foreground symbol is displayed on the player side. Approach or move away. In other words, if the enlargement / reduction value is sequentially increased, the foreground symbol can approach the player side, and if the enlargement / reduction value is successively reduced, the foreground symbol can be displayed away from the player side. Therefore, since the symbols can be moved more realistically, the player can enjoy watching the special symbol display device 122.

As described above, by setting an optimal symbol combination pattern according to the animation display process, a three-dimensional screen or a deep animation can be displayed on the screen of the special symbol display device 122. it can. For this reason, in addition to the pleasure of winning the game ball, the player is given the pleasure of watching the special symbol display device 122, so that the player can be kept interested. In addition, by designating various values as element parameters (vector value, rotation value, scroll value, scaling value), symbols with various screen positions, orientations, and sizes using only one symbol data Can be displayed. Accordingly, it is not necessary to prepare various symbol data having different screen positions, orientations, and sizes, so that the amount of data necessary for displaying an animation can be reduced.

In the above combination pattern, as shown in FIG. 9 and FIG. 10, the data of the color number, vector value, priority order, coordinate value, rotation value, scroll value, and enlargement / reduction value, which are element parameters, are different from each other. Although it is configured with a data structure, it may be configured with a data structure including elements obtained by arbitrarily combining these data. For example, a parameter [symbol number, color number, vector value] is a single element, and a combination pattern consisting of a data structure having a plurality of these elements specifies the color of the pattern and the moving direction of the pattern. Can do. Similarly, the parameter [symbol number, priority, coordinate value] is one element, and the combination pattern consisting of a data structure having a plurality of these elements specifies the display position of the symbol from the foreground, and within the frame. The display position of the symbol can also be specified.

In this way, various designations can be made with one data structure by combining target parameters as one element. That is, a combination of at least one parameter among each parameter {color number, vector value, priority order, coordinate value, rotation value, scroll value, display period, enlargement / reduction value} and a design number is used as one element. Good. There are a total of 255 such combinations, and examples of combinations other than those described above are shown below.
(1) [Design number, color number, priority]
(2) [symbol number, color number, coordinate value]
(3) [symbol number, vector value, priority]
(4) [symbol number, vector value, coordinate value]
(5) [Design number, color number, vector value, priority]
(6) [symbol number, color number, vector value, coordinate value]
(7) [Design number, color number, priority, coordinate value]
(8) [symbol number, vector value, priority, coordinate value]
(9) [Design number, color number, vector value, priority, coordinate value]

Returning to FIG. 8, after the step S24, a one-screen setting process is performed to display a combination of a plurality of symbols in accordance with the parameters of each element designated in the read combination pattern (step S26). Specifically, as shown in FIG. 11, an item setting process is performed (step S40), and the ROM 224 is set in accordance with the symbol number designated by the combination pattern.
The corresponding symbol data is read out from the frame and transferred to the frame memory 232 (step S42).
). Steps S40 and S42 are repeated by the number of elements specified by the combination pattern (step S44). By this processing procedure, the special symbol display device 122 displays one screen according to the combination pattern.

In the item setting process in step S40, specifically, as shown in FIG. 12, first, the color of the symbol is set (step S50), and the vector value for moving the symbol is set (step S5).
2) Set the frame position to transfer the symbol (step S54), set the coordinates (transfer position) in the frame set in step S54 (step S56), and set the rotation value to rotate the symbol (step S56) In step S58, a scroll value for scrolling the symbol is set (step S60), and an enlargement / reduction value for enlarging (or reducing) the symbol is set (step S62).

In step S50, the color is set by palette control according to the color number.
The pallet control will be briefly described below. The colors that can be displayed by the special symbol display device 122 are determined by the luminance levels of the primary colors of the three primary colors (red, blue, and green). For example, if 8-bit data is assigned to the luminance levels for the three primary colors, 8 3 = 512 colors can be displayed. However, in this case, a huge amount of data is required even if only one screen is displayed, so 1-bit data is assigned to each of the three primary colors, and the specifiable colors are 2 3 = 8 colors. Then, when the power is turned on or when the game state changes, the color to be displayed with respect to the color of the designated number is selected in advance from 512 colors in the above case, and consecutive numbers are assigned in ascending order. deep. Thereafter, the eight colors selected according to the color number are displayed. Such control for displaying a series of colors is called palette control. By this palette control, it is possible to select and use arbitrarily from among many colors even if the number of colors to be developed at the same time is small. Note that the number of bits of data assigned to the three primary colors and the luminance level is not limited to the above number of bits. That is, an appropriate number of bits may be set in accordance with the content of the symbol displayed on the special symbol display device 122.

Here, a specific example of symbols displayed on the special symbol display device 122 will be described with reference to FIGS. 13 and 14. In FIG. 13A, the symbol 700 indicating the number “7” is displayed in the central portion of the screen of the special symbol display device 122 by the coordinate value setting in step S56 described above. If step S56 is not executed, it is displayed in the upper left part (symbol 702) of the screen. Hereinafter, the change from the position of the symbol 700 is shown below. Further, the symbol 700 is moved and displayed on the lower right portion (symbol 704) of the screen as shown in FIG. 13B by the vector value setting (for example, movement in the arrow D1 direction) in step S52.

Similarly, the rotation value is set in step S58 (for example, counterclockwise, that is, 9 in the direction of arrow D2).
With the rotation of 0 degree, the symbol 700 is displayed horizontally (symbol 706) in the center of the screen as shown in FIG. 13C. Further, the scroll value setting in step S60 (for example, the arrow D3
By moving in the direction), the symbol 700 is displayed at the upper center of the screen (symbol 7) as shown in FIG.
The image is displayed while scrolling to (08). Then, by setting the enlargement / reduction value in step S62 (for example, enlargement to double in the vertical and horizontal directions), the design 700 is enlarged (design 710) at the center of the screen as shown in FIG.

Then, if complex setting is performed, the symbol 700 is enlarged at the lower right portion of the screen as shown in FIG. The settings in this case are a vector value (movement in the direction of the arrow D1), a rotation value (rotation 45 degrees counterclockwise), and an enlargement / reduction value (enlarged twice vertically and horizontally). In this way, by performing complex settings, it is possible to display a more complicated symbol. On the other hand, since the original symbols required for display can be minimized, the storage capacity of the ROM 224 for storing symbols can be kept low.

In addition, you may perform the process of step S50 thru | or step S62 shown in FIG. 12 changing the order to set to arbitrary orders. In this case, whether to execute each step is determined according to the element specified by the combination pattern. For example, each element of the combination pattern 620 shown in FIG. 9C has only a vector value in addition to the symbol number.
Only 52 is executed. Similarly, since each element of the combination pattern 540 shown in FIG. 9E has only a coordinate value in addition to the symbol number, only step S56 is executed.

Moreover, you may abbreviate | omit as needed irrespective of the element designated with a combination pattern. That is, if step S50 is omitted, monochrome display is obtained, and if step S52 is omitted, the symbol is fixed without moving on the screen. Similarly, if step S54 is omitted, the frame with the highest priority is selected first, and the frames with the lower priority are selected thereafter. Further, if step S56 is omitted, the first coordinates (for example, the upper left coordinates on the screen) corresponding to the entire surface of the frame are designated. If step S58 is omitted, the symbol will not rotate. If step S60 is omitted, the symbol will not scroll. If step S62 is omitted, the symbol size will not change.

Returning to FIG. 8 again, the image display processing in step S28 is repeated only within the display period specified by the scenario data (step S30). Thereafter, the above-described steps S24 to S30 are repeated by the number of elements specified by the scenario data (step S32).
. In this way, the symbols having the contents designated by the scenario data are continuously displayed on the special symbol display device 122 (that is, like an animation).

Next, specific processing contents of the image display processing will be described with reference to FIG. First, a shift process for moving the symbol in accordance with the vector value set in step S52 shown in FIG. 12 (step S70), a rotation process for rotating the symbol in accordance with the rotation value set in step S58 (step S72), A scroll process for scrolling the symbol in accordance with the scroll value set in step S60 is performed (step S74), and an enlargement / reduction process for enlarging (or reducing) the symbol in accordance with the enlargement / reduction value set in step S62 (step S76). Note that the processing in these steps is performed for each frame.

After that, all the frames to be displayed are scanned along the raster direction, and in the portion where the symbols overlap, the symbol having higher priority than the symbol having lower priority is prioritized and converted to an image signal.
A scan process for outputting to the special symbol display device 122 is performed (step S78). Through this scanning process, the symbols with high priority are combined with priority so that the symbols are displayed in the foreground at the portion where the symbols overlap, and are displayed on the special symbol display device 122. That is, a symbol with a low priority is displayed in a state hidden behind a symbol with a high priority. In addition, you may comprise so that a symbol with a low priority may be superimposed on a symbol with a high priority. With this configuration, a more complicated screen display can be performed.

Thus, by the execution of the image processing means 50, a symbol (or a symbol designated by a combination pattern) is read according to the scenario data stored in the ROM 224, and the read symbol is synthesized and converted into an image signal to be a special symbol. It is output to the display device 122. For this reason, an animation according to the scenario data is displayed on the special symbol display device 122. For example, FIG. 16 and FIG. 17 show examples of animations that introduce characters to be displayed on the special symbol display device 122 at the start of the game of the ball game machine 100. That is, while moving the character symbols 800, 802, and 804 in the left direction of the screen (in the direction of arrow D10), the process is performed from FIG. 16A through FIG. 16B to FIG. Then, the names and features are introduced in the order of the appearing characters in the order of FIG. 17 (A), FIG. 17 (B), and FIG. 17 (C).

Similarly, FIG. 18 and FIG. 19 show examples of animations for notifying the player of the current gaming state in a state where a special benefit is given to the player (that is, a “big hit” state). That is, in FIG. 18, first, pieces of disjointed pieces appear on the special symbol display device 122 (FIG. 18A), and these pieces are gradually gathered to form a “big hit” character [FIG.
B)], an animation that scatters in all directions is developed [FIG. 18C]. In FIG. 19, a symbol 900 simulating a small earth appears in the center of the screen of the special symbol display device 122 (FIG. 19D), and this symbol 900 rotates in the direction of the arrow D20 in the same manner as the rotation of the earth. However, it gradually increases [FIG. 19 (E)]. After that, as shown in FIG. 19 (F), a special benefit is given to the player while changing the background etc. according to the number of game balls B won in the special area (winning slot 132 shown in FIG. 2). It continues during In the case of the figure, the number of game balls B won in the special area is displayed as a symbol 902 in the upper left part of the screen of the special symbol display device 122.

In addition, when the game ball B wins the starting opening during the game and the symbol displayed on the special symbol display device 122 matches a predetermined symbol and becomes a “hit”, the special symbol display device 122
A predetermined symbol is displayed on the entire background, and a symbol that changes each time the game ball B passes the special area (winning hole 132 shown in FIG. 2) is displayed on the foreground of the special symbol display device 122. Such a display state is performed only during a period in which “big hit” is established. By performing the display control described above, it is possible to provide the player with a screen that is full of changes and displays an animation that is optimal for the gaming state, and to provide satisfaction due to “big hit”. For this reason, in addition to the pleasure to win a game ball, the pleasure to see the special symbol display device 122 is given. Also, by designating the music number in the scenario data, it is possible to play the BGM that is optimal for the gaming state, so that the player can be interested without getting bored.

Furthermore, since the color of the symbol changes on the screen of the special symbol display device 122 by the color setting (coloring process) in step S50 shown in FIG. 12, a screen having an impact according to the gaming state is given to the player. Can do. As another method for changing the color of the design, there is the following method. That is, a symbol that is displayed on the screen of the special symbol display device 122 and sets a state that gives a special benefit to the player is determined in advance. And probability switching means 30
In response to the probability obtained as a result of executing step S50, the color setting (coloring process) in step S50 is performed.
In FIG. 5, the color of the symbol is changed on the screen of the special symbol display device 122. According to this configuration, the player can easily determine the state of the switched probability (that is, the current gaming state) only by looking at the type of color colored in the symbol.

In addition, a configuration in which the color of a symbol displayed in the background (or foreground) according to the priority set in the combination pattern (data structure) is set corresponding to the probability obtained as a result of executing the probability switching means 30. It is good. For example, when the probability of “big hit” is set high, the color of the symbol displayed on the background is changed to red. According to this configuration, there is no need to change the determination symbol or other decorative symbol for determining “big hit” on the screen of the special symbol display device 122 according to the probability value, so that the internal processing is simplified and the probability state is You can quickly see what has changed.

Although one embodiment of the ball game machine has been described above, the structure, shape, size, material, number, arrangement, operating conditions, etc. of other parts in this ball game machine are also limited to this embodiment. It is not something. For example, a color liquid crystal display device is applied to the display device 60 (specifically, the special symbol display device 122, hereinafter the same), but like a CRT or LED,
Other display devices capable of displaying symbols may be applied.

In addition, although the case of animation is applied as the continuous display based on the scenario data, for example, the game room guidance (character information) is displayed to the player, or the game method of the ball game machine 100 is displayed. As described above, the present invention can be applied even when information that cannot be displayed on one screen is continuously displayed. Similarly, each time the game ball B wins a predetermined winning slot from the start of the game of the ball game machine 100, the content is displayed along the outline of “Momotaro Monogatari”, for example.
It may be displayed as 0 and continuously displayed by scenario data having narrative characteristics so that it becomes a “big hit” at the stage of demon extermination. With this configuration, the player can enjoy the special symbol display device 122 in addition to the pleasure of winning the game ball.

The scenario data is not limited to the data structure including the parameters of the elements shown in FIG. 7, but may be composed of a data structure including the parameters shown in FIGS. That is, a combination of at least one parameter among each parameter {music number, color number, vector value, coordinate value, rotation value, scroll value, enlargement / reduction value} and symbol number may be used as one element. Note that the {vector value, rotation value, scroll value, enlargement / reduction value} parameters are parameters for acting on the entire screen. For example, if you set a vector value, the entire screen moves in the direction set by the vector value, if you set a rotation value, the entire screen rotates in the direction set by the rotation value, and if you set a scroll value, the entire screen Scrolls in the direction set by the scroll value.

There are 126 combinations as described above, and examples of such combinations are shown below. Here, the case where the parameters are {music number, color number, vector value} and symbol number is shown.
(1) [symbol number, color number]
(2) [symbol number, music number, color number]
(3) [symbol number, vector value]
(4) [symbol number, music number, vector value]
(5) [symbol number, color number, vector value]
(6) [Design number, music number, color number, vector value]

In addition, the symbol data transfer process (step S14 shown in FIG. 6, step S shown in FIG. 11).
42), the symbol data stored in the ROM 224 is directly transferred to the display control circuit 234. However, the symbol data is compressed in a predetermined format and stored in the ROM 224 in advance, and the compressed symbol data is stored in the ROM 224. May be configured such that the compressed symbol data is expanded (restored) and transferred to the display control circuit 234 when the symbol is read and displayed on the special symbol display device 122. In this configuration, by compressing the symbol data and storing it in the ROM 224, the capacity required to store the symbol data can be greatly reduced. For this reason, the necessary ROM
The capacity of 224 can be reduced, and as a result, the cost of the ball game machine 100 can be kept low.

Here, as a method of compressing symbol data, MR (modified READ) method or MMR (MMR (
modified modified READ) method is desirable. In these methods, the MH method (modified Huf
fman; a method of encoding the continuous length of black or white generated one-dimensionally in the row direction, the shorter the higher the frequency of occurrence, the shorter the second row, the second and subsequent rows Encoding is performed using the difference, and the number of differential encoding lines (k) is limited, and encoding is performed by the MH method for each k-th line.
Therefore, efficient compression can be expected (about 1/10 to 1/15 when k = 2, 4). Therefore, the storage capacity of the memory can be greatly reduced. Similarly, Run-Leng
th) Coding method, LZ (Lempel-Ziv) coding method, arithmetic coding method, LZSS coding method, LZW
The symbol data may be compressed by an encoding method such as a (Lempel-Ziv-Welch) encoding method. According to these encoding methods, a compression rate comparable to that of the MR method or the MMR method can be obtained. Other compression (encoding) suitable for compressing symbol data (image data)
The symbol data may be compressed by a method. For example, there are a Huffman method (a method for giving a short bit string to a pattern having a high appearance frequency), a continuous code compression method (a method for converting a continuous code to a short length), and the like.

The symbol data is stored in the ROM 224, which is one of the symbol storage means 40. However, the symbol data can be changed by transferring (or developing) the symbol data from the ROM 224 to the RAM 226 in advance when the power is turned on or reset. When doing so, the symbol data may be transferred from the RAM 226 to the display control circuit 234. Generally, since the access time of the RAM 226 is faster than the access time of the ROM 224, the time required for transferring the symbol data to the display control circuit 234 can be shortened.

(Effects of the Invention) As described above, the invention of claim 1 is configured such that the symbols stored in the symbol storage means are sequentially displayed on the screen of the display device in accordance with the scenario data corresponding to the current gaming state. Therefore, the player is given pleasure not only to enjoy the game but also to see the symbols that change sequentially for each game state. Therefore, since the same symbol is not repeatedly displayed on the display device, the player does not get tired of watching the display device.

Further, in the invention of claim 2, since the symbols stored in the symbol storage means are sequentially displayed on the screen of the display device according to the scenario data and the combination pattern corresponding to the current gaming state, The symbols synthesized by the combination pattern are displayed with different animations for each gaming state. Therefore, display can be performed with a deep animation, and the player can enjoy watching the display device.

Further, according to the invention of claim 3, since the probability switching means switches the probability according to the current gaming state and the scenario data is selected according to this probability, the animations differing with the probability even in the same gaming state. Is displayed. Therefore, it is possible to display with a more varied animation and entertain the player.
