DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine,
More specifically, the present invention relates to a control configuration of an image control board that controls display of an image corresponding to the progress or content of a game.

[0002]

2. Description of the Related Art In a gaming machine, for example, a pachinko gaming machine, when a fired game ball wins or passes through a starting opening, a symbol is displayed for a predetermined time on a screen, and then displayed statically (stop display). If the statically displayed symbol is a combination of a predetermined symbol, the game content is in a state advantageous to the player. Whether or not to display a predetermined combination of symbols indicating that the player is in an advantageous state is determined by the value of a random number selected based on the timing at which the game ball has won the starting port or passed through the passing port. If the selected random number value matches a predetermined value, a combination of a plurality of symbols, for example, “777” is displayed on the screen.
Or, a combination of predetermined symbols such as "333" is displayed to inform the player that the game content is advantageous to the player, and a so-called "big hit" is opened to the player for a predetermined time by opening a special winning opening or the like to the player. A large amount of game balls are paid out as prize balls. Generally, the selected random number value is configured as a counter that repeatedly generates an integer value within a predetermined range by incrementing by +1 (increment) every minute time such as a hardware interrupt,
Because the timing at which the game ball wins the starting port cannot be predicted, that is, the appearance rate of the random number component is uniform,
Since each element is randomly extracted, it functions as a random number. In the pachinko gaming machine, the progress and content of the game, such as the extraction of the random value and the determination of the random value or opening of the winning port, are referred to as a "main control board" (hereinafter simply referred to as "main control board"). ), And image control processing such as displaying a combination of predetermined symbols on a screen is executed by an image control board (also referred to as a “symbol control board”). Conventionally, communication between the main control board and the image control board has been executed by a so-called “offset method”.

In this offset method, data corresponding to the type of symbol and the display position of the symbol is transmitted from the main control board to the image control board for a predetermined time, for example, at each hardware interrupt, and a predetermined number of frames are transmitted per second. Was controlled to display the image. However, transmitting data at every hard interrupt or at every time corresponding to the hard interrupt means that the timing of increment of the random number value is known outside the main control board. There was no danger of improper use of this to forcibly generate a big hit. In addition, in recent years, various interesting controls have been performed on display control on a screen for the purpose of developing image control technology and providing a player with more entertainment. For example, in order to give a sense of expectation of a big hit, control such as suddenly appearing a character while the design is changing, changing the background screen, or incorporating a so-called reach operation or a trick operation in the change display mode of the design is performed. It has been done. These controls are also executed by instructions from the main control board, but frequent execution of these instructions by the main control board is a problem that the processing load on the main control board is large. There is a problem that the degree of freedom of control is impaired by frequent instructions from the user. Therefore, in order to eliminate the possibility of the fraud and increase the degree of freedom of the image control board, an invention called "intelligentization" described below has been made.

[0004] In a gaming machine adopting an invention called "intelligentization", data is transmitted from the main control board to the image control board at the time when the image changes. That is, at the start of the fluctuation of the displayed symbols, at the time of the variation of the variation speed, at the time of the stationary variation, and the background screen displayed on the screen corresponding to the displayed symbols and the background screen of different types of characters. At the time of the change or when a different type of character is displayed, data is transmitted from the main control board to the image control board to execute the change of the image, and the change is instructed. The gaming machine adopting this intelligence has an extremely excellent effect of preventing the occurrence of fraud since the timing of transmission from the main control board to the image control board is different from the timing of increment of the random number value. ing.

[0005]

However, even in a gaming machine adopting the above-described intelligent system, the main control board causes the image control board to change the pattern, background, character, etc. constituting the image at each time the image changes. It is necessary to transmit data to instruct, and the burden on the main control board for executing various controls is still large. On the other hand, in the image control board, there is no change in the configuration instructed by the main control board every time the image changes, and the degree of freedom that the image control board independently determines and executes various image processing is still low. Is the actual situation. The present invention suitably solves these problems, enables the main control board to execute various controls other than image control more precisely, and further increases the degree of freedom from the main control board in the image control board. An object of the present invention is to provide a ball game machine capable of expressing an interesting image and providing a player with a sense of entertainment.

[0006]

According to a first aspect of the present invention, there is provided a ball game machine in which a game ball fired on a game board enters a specific entrance or a specific ball. A decision unit for determining whether or not to make the game content advantageous to the player according to a random number value extracted due to a timing of passing through the passage opening; and determining whether or not to shift to a game content advantageous to the player. A winning / failing image determining means for determining the type of the winning / failing image to be shown; and displaying the image on the screen variably each time the determining means determines whether or not the game content is advantageous to the player, and then determining the winning / failing image. Image control means for controlling to display a still image with a hit / fail image by means, and a basic variation pattern which is selected as one of conditions as to whether or not the game content is advantageous to the player by at least the hit / fail determination means. Basic Moving pattern determination means, and the basic fluctuation pattern determination means, the hit / fail image determination means and the hit / fail determination means on the main control board, the image control means on the image control board, the ball game machine equipped with Further, the image control board further includes display pattern selecting means for allocating the basic variation pattern determined by the basic variation pattern determining means of the main control board to two or more display patterns. The image control means is configured to variably display the image in accordance with the display pattern distributed by the means.

[0007] Here, it is determined whether or not to provide a game content advantageous to the player due to the timing at which a game ball fired on the game board enters a specific entrance or passes through a specific passage. The term "determined" naturally includes a state where the player enters a state directly advantageous to the player by the value of the random number extracted due to the timing of entering a specific entrance or passing through a specific passage. A predetermined winning opening (entrance opening) is opened by a value of a random number extracted based on a timing at which a ball enters a specific opening or passes through a specific passing opening, and a specific winning opening which has been opened is specified. A state in which a gaming machine such as a so-called "third-type gaming machine (rights)" or an "arranged ball gaming machine" has an advantage indirectly advantageous to the player when the gaming ball passes through the area. The game content to be played is also included. It should be noted that the configuration may be such that a game ball as a prize ball is paid out upon entry of a ball (in this case, it is often called a “winning opening”), or a configuration may not be provided.

[0010] Each time the main control board determines whether or not to make the game content advantageous to the player, the hit / fail image may be an image showing the determination result to the player. Or an image indicating a game or a win or loss in a game, an image indicating a race result in a race scene, or the like, to determine whether or not a game content advantageous to the player is executed. It may be configured as shown. In addition, the type of the winning / failing image is not limited to a type of simply determining whether or not the game content is advantageous to the player according to the display mode, but also an image or advantageous game content indicating the advantageous game content. Even if the image indicates that the image is not displayed, the type is classified according to the difference in the display mode of the image. The image is displayed on the screen, and includes a figure indicating a numeral, a character, a person or an animal, a specific color of a specific shape, and the like. The screen means not only the screen of the CRT and the liquid crystal display, but also the dot matrix display and the 7-segment LED.
Etc. refers to a display unit of a device capable of displaying the image. Note that “still in the hit / fail image” refers to a display mode in which a fluctuating image appears as determined by the hit / fail image, and also includes a mode in which the player image appears to be determined even if the image is not completely still.

According to the first aspect of the present invention, in the ball game machine, the basic variation pattern of the image determined by the basic variation pattern determining means of the main control board is displayed on the image control board by two or more display pattern selecting means. The image is distributed to display patterns, and the image control means variably displays the image in accordance with the allocated display patterns, and serves to statically display the pass / fail image determined by the pass / fail image determination means of the main control board.

Thus, the ball game machine according to the first aspect can reduce the number of image fluctuation patterns to be created on the main control board, thereby reducing the processing load on the main control board. And the degree of freedom in image processing can be increased without reducing the number of fluctuation patterns displayed on the image control board.

[0011] The ball game machine according to the second aspect is the first aspect.
Wherein the hit / failure image is configured by a combination of two or more symbols, and the display pattern selecting means is configured to be sorted according to the combination of the symbols forming the hit / failure image.

A ball game machine according to a second aspect of the present invention is configured so that display patterns to be sorted by the display pattern selecting means are sorted according to a combination of symbols as hit / failure images. Thereby, the ball game machine according to claim 2 has an effect that it is possible to create a display pattern in accordance with the combination mode of the symbols as the hit / failure image.

[0013] The ball game machine described in claim 3 is claim 1.
Wherein the display pattern selection means is configured to be sorted by a value of a random number extracted by the image control board.

According to a third aspect of the present invention, there is provided a bullet-ball game machine wherein a display pattern allocated by the display pattern selecting means is allocated according to a value of a random number extracted by the image control board. Thus, the ball game machine according to claim 3 has an effect that a display pattern can be created according to the number of elements constituting the random number extracted by the image control board.

It is configured as a communication circuit.

The processing executed by the 8-bit one-chip microcomputer (hereinafter simply referred to as "microcomputer") in the main control board 30 of the pachinko machine 10 having the above-described circuit configuration will be described with reference to the flowchart shown in FIG. To The flowchart shown in FIG.
Represents the main processing executed by the microcomputer, and is a processing periodically executed by a hard interrupt every about 2 ms. In this embodiment, steps S100 to S100
Each process up to 200 is a process that is executed only once in the interrupt process, and is referred to as “main process”, and steps S210 and S220 are repeatedly executed as long as time permits within the extra time after executing the main process. Is referred to as “residual processing”.

When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (step S100). This determination process is performed by using R
This is performed by determining whether the value of the predetermined area of the AM is a predetermined value. When the processing executed by the microcomputer shifts to this processing, it is determined whether the normal processing can be performed. For. When the power is turned on or runaway of the microcomputer due to noise or the like is considered as an abnormal case, the runaway of the microcomputer can be considered to be almost nonexistent due to the improvement of technology in recent years. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value. If it is determined that the symbol is not normal, a predetermined value is written to a predetermined area of the memory, and each initial value is written to a work area of the memory, such as a special symbol and a normal symbol as an initial symbol. In step S110), the process proceeds to a residual process.

When the affirmative determination is made, a process of updating initial random numbers is executed (step S120). As shown in FIG. 6, this process is an increment process that increments the value of the initial random number by one each time this process is executed. The value of the initial random number before this process is executed is incremented by one. When the random number value of is “249” which is the maximum value, it returns to the initial value “0” in the next processing, and “0” to “2”
The 250 integers up to "49" are repeatedly created in ascending order. The success / failure random number update process (step S130) subsequent to step S120 is an increment process of incrementing by +1 each time the process is executed in the same manner as the initial random number update process. However, as shown in FIG. In the next process, the value of the initial random number at that time is set to an initial value (hereinafter, referred to as the initial value).
It is called "update initial value". ), And +1 for each interrupt
If the value of the initial random number at that time is further reduced by "1" (hereinafter referred to as "update maximum value") to the value of "1" less than the initial value of the update, the value of the initial random number at that time is set as the initial value in the next process.
250 integer values up to “249” are repeatedly created.

That is, the value of +1 is incremented every time an interrupt is processed, and the elements constituting the random numbers are set to integer values from “0” to “249”, which are not different from the initial random numbers at all. Then, in the next interrupt processing, the update initial value at that time is set as an initial value, and +1 is added for each interrupt until the update maximum value is reached, and the next update initial value is set as the initial value. As a result, the pass / fail random number is set to 250 integer values from “0” to “249” as elements constituting the random number, and is incremented by one for each interrupt processing. Since the value is changed to a value determined by the initial random number at that time, the value of the pass / fail random number can be made unpredictable. Also, the components of the random number determined by the update initial value and the update maximum value do not change at all from the 250 integer values of “0” to “249”, which are the same as the conventional pass / fail random number, so that the elements constituting the random number are not changed. Has a uniform appearance rate.

Big hit symbol random number update processing (step S14)
0) is configured as a counter for repeatedly creating 15 integers from “0” to “14”, and is incremented by 1 every time this processing is performed, and returns to the initial value “0” when exceeding the maximum value. The fifteen random numbers “0” to “14” are the same three digits “000”, “111”, “222”, and “33” displayed on the screen.
3 "," 444 "," 555 "," 666 "," 77 "
7 "," 888 "," 999 ", [AAA]," BB
B "," CCC "," DDD ", and" EEE ". The out-of-design symbol random number update process (step S150)
It consists of a random number for the left symbol, a random number for the middle symbol, and a random number for the right symbol, and is used as a missing symbol when there is no big hit.
The left symbol random number is configured as a counter that repeatedly generates 15 integers of “0” to “14”, and +
If it is incremented by 1 and exceeds the maximum value, it returns to the initial value "0". The medium symbol random number is configured as a counter that repeatedly generates fifteen integers from "0" to "14". Return to "0". The random number for the right symbol is 1 from "0" to "14"
It is configured as a counter that repeatedly creates five integers, and is set to 1 each time the medium symbol random number returns to “0”, and returns to “0” when it exceeds the maximum value. The normal symbol random number update process (step S160) is configured as a counter that repeatedly generates seven integers of “0” to “6”, and is incremented by +1 in this process to return to the initial value “0” when exceeding the maximum value. Return.

The above-described random number updating processing (step S12)
0 to S160), the initial random number, the pass / fail random number, the jackpot symbol random number, the out-of-sync symbol random number, and the ordinary symbol random number are updated. In the subsequent processing (step S170), the pachinko machine 1
The input processing of each switch provided at 0 and connected to the main control board 30 is executed. In the present embodiment, the full tank switch 43, the supply switch 44, and the touch switch 2
4a, a first type start switch 36a, a V switch 40a,
Count switch 40b, normal symbol operation switch 38a
And 39a, and a process of checking the operation status of each switch such as a prize detection switch (not shown) provided in the other prize port. When there is an input to the first-type starting port switch 36a by this input processing, it means that the game ball has won the ordinary electric accessory 36 as a starting port,
The value of the random number at the time of this interrupt processing is extracted and compared with the determination value.

The pachinko machine 10 according to the present embodiment is configured as a probability varying machine, and the judgment value is "1" at the time of normal probability, and "1", "3", "5", "7" at the time of high probability. "
"9". As described above, the appearance rate of each of the 250 integer values of “0” to “249” constituting the random number is uniform, and is extracted at the timing when the game ball wins the ordinary electric accessory 36 as a starting port. The value of the random number is randomly extracted as compared with 2 ms, which is the minute time of the hard interrupt, because the winning timing cannot be adjusted in minute time units, and the random number functions as a complete random number. Therefore, the probability that the value of the extracted success / failure random number matches the success / failure determination value and becomes a big hit is 1/250 at a normal probability and 1/50 (= 5/25) at a high probability.
0). The reason why the probability of generating the big hit changes from the low-probability state to the high-probability state is that, in the present embodiment, the values of the above-described big hit symbol random numbers in the interrupt processing at the time of the occurrence of the big hit are “1,” “3,” and “3”. 5 "," 7 "," 9 ",
This is the case of “11” and “13” (hereinafter referred to as “high-probability random number”), and is 7/1 when a jackpot occurs.
It shifts to a high probability with a probability of 5. Then, during the high probability, if the value of the big hit symbol random number when the big hit is generated again is the high probability random value, the high probability state continues. That is, there is a possibility that the high probability will continue at a probability of 7/15 every time the state becomes the high probability state once. When the success / failure determination process (step S180) ends, an image output process (step S190) is subsequently performed. This image output processing will be described later in detail.

The subsequent output processing (step S200)
In accordance with the progress of the game, the main control board 30 includes a special symbol display device 32, a prize ball control board 31, a launch control board 33, a lamp control board 34, a sound control board 35, and a special winning opening solenoid 4.
Output processing is executed for each of various solenoids such as 0c. That is, when it is detected by each of the input processes (step S170) that a game ball has been won at each of the winning ports on the game board 22, the prize ball control board 31 pays out the game ball as a prize ball. The process of outputting ball data, the process of outputting sound data corresponding to the game state to the sound control board 35, the error signal is sent to the symbol control board 32b to notify that the pachinko machine 10 is in error when there is an abnormality. , And a jackpot process when a jackpot occurs.

The remaining process subsequent to the above-described process includes an out-of-design symbol random number updating process (step S210) and an initial random number updating process (step S220). The remaining processes are exactly the same as the above-described steps S150 and S120, respectively. is there. These two processes form an infinite loop and are repeatedly executed as long as time permits until the next interrupt is executed. The time required to execute the main processing of steps S100 to S200 described above differs for each interruption depending on whether or not to execute the jackpot processing, a difference in a special symbol display mode, and the like. As a result, the number of times the residual process is executed also differs for each interrupt, and the updated (added) values of the out-of-design symbol random number and the initial random number are not uniform by executing the interrupt process shown in FIG. 5 once. Disappears. This eliminates the possibility that the initial random number and the out-of-design symbol random number are synchronized with the pass / fail random number. In this embodiment, since the update of the random number is changed by the value of the initial random number, there is no possibility of synchronization. Also, the above-described ordinary symbol random number updating process (step S160) may be configured to be executed in the remaining process.

By executing the above-described processes, the pachinko machine 10 executes the following operation. Game balls are fired on the game board 22 by the firing motor 33a in accordance with the amount of rotation of the firing handle 24 operated by the player, and the shot game balls are fired on the ordinary electric accessory 3 as a first type starting port.
6 is detected by the first-type start-up switch 36a, the special symbol is displayed in a special symbol display area 50a to 50c (see FIG. 8) on the screen of the LCD 32a of the special symbol display device 32 (see FIG. 8) for a predetermined time, and then stopped. Work to display.
This special symbol that is displayed statically is a predetermined specific symbol,
For example, when the same three-digit symbol such as "777" is displayed, the game is provided as a big hit state, which is advantageous to the player. Whether or not the big hit state is determined is based on whether or not the value of the success / failure determination random number extracted when the game ball is detected by the first-type starting port switch 36a is a predetermined value.

When the jackpot state is reached, the special winning opening 40 is opened for about 30 seconds or until the count switch 40b detects that 10 game balls have been won, whichever comes first. At this time, the special winning opening 40 is opened. When the V-switch 40a detects that the game ball that has won inside passes through the special area, the large winning opening 40 is once closed and then opened again, and this opening operation is repeated up to 16 times. Usually, 15 game balls are paid out as prize balls for one game ball winning. Therefore, when one big hit state occurs, about 2400 (= 15 × 10 × 16) pieces are obtained. Game balls can be acquired as prize balls. The prize ball discharging operation is executed by the prize ball control board 31. The V solenoid 40d that opens and closes the special area of the special winning opening 40 is for closing the special area when one game ball passes through the special area. In addition, although the ordinary electric accessory 36 wins the game ball even in the normal state, when the value of the normal symbol random number extracted at the timing when the game ball passes the ordinary symbol operation gate 38 or 39 is a predetermined value, the Entrance is enlarged and winning is easy. The time required for the ordinary electric accessory 36 to expand is 0.3 seconds in the normal state and 1.5 seconds in the case of the high probability described above. Also, the normal symbol operation gate 38
Alternatively, the normal symbol fluctuating time from the time when the game ball passes through 39 to the time when it is fluctuated and then stands still is 20 seconds in a normal state, and 5 seconds to 6 seconds in a high probability. This allows
At high probability, it is less likely to be stored on hold,
The number of times of deriving the determination result of whether or not to enlarge the ordinary electric accessory 36 by the ordinary symbol can be made larger than that in the ordinary state.

Here, the above-described image output processing (step S190) will be described in detail with reference to FIG. The command code shown in FIG. 9 is a code transmitted from the main control board 30 to the symbol control board 32b of the special symbol display device 32. As shown in FIG. 9, the transmission command codes of the main control board 30 and the symbol control board 32b of this embodiment are: 1. When power is turned on. 2. Customer waiting demo; 3. While the design is changing. 4. At the start of the jackpot During the jackpot, 6. At the end of the jackpot, 7. At the time of abnormal operation, it can be roughly classified into seven types.

1. The power-on command is a command code transmitted from the main control board 30 to the symbol control board 32b when the pachinko machine 10 is powered on.
Is composed of a two-byte instruction having an identification number of When the symbol control board 32b receives this command, a demo screen at the time of power-on is displayed on the screen of the LCD 32a according to the control program written in the ROM.

2. Customer Waiting Demo The customer waiting demonstration command is transmitted after the power-on demonstration screen is completed, or when it is determined that the player has not touched the firing handle 24 for a predetermined time (usually about 3 minutes). And is composed of a 2-byte instruction having an operation number of 20H and an identification number of 01H. Symbol control board 32b
Upon receiving this command, a demo screen waiting for a customer is displayed on the screen of the LCD 32a in accordance with the control program written in the ROM. For example, the variation patterns of the special symbols which are variably displayed on the special symbol display areas 50a to 50c shown in FIG. 8 are sequentially displayed. Also, the hold storage display unit 51
a to 51d are sequentially lit and displayed. At this time, the background screen 5
On 2, a background image and a character corresponding to each variation pattern are displayed. The customer waiting demonstration screen displays all the variation patterns in order until the player operates the firing handle 24, makes one round, and then repeatedly displays it. Note that whether or not the player is touching the firing handle 24 can be detected by inputting the touch switch 24a. In this embodiment, the input of the touch switch 24a is
Therefore, the detection can be performed while the communication between the main control board 30 and the emission control board 33 is one-way communication from the main control board 30. Of course, the on / off information of the touch switch 24 a is transmitted from the main control board 30 to the emission control board 33. This touch switch 2
4a is input to the launch control board 33, and there is no prize in any or all prize ports for a predetermined time;
Alternatively, a switch may be provided in the out port 41 of the game board 22 to determine that the player is not playing a game by turning off this switch for a predetermined time.

3. The symbol changing command is a command transmitted when the special symbol is changed. As shown in FIG. 9, (1) basic changing pattern code, (2) left stationary symbol designating code, (3) middle stationary symbol designating And four types of command codes, (4) right stationary symbol designating code (hereinafter, these four command codes may be collectively referred to as "image display command").
are categorized.

(1) Basic variation pattern code The basic variation pattern code is configured as nine types of two-byte instructions from a one-byte instruction of 30H as an operation number and nine types of one-byte instructions of 01H to 09H as identification numbers. I have. The nine types of one-byte instructions will be described later in detail. (2) Left stationary symbol designation code The left stationary symbol designation code is an instruction code consisting of an operation number of 31H and 15 types of identification numbers of 01H to 0FH. When the identification number is 01H, "0" is designated as a left stationary symbol. ”, 02H is“ 1 ”, 03H is“ 2 ”, 04H is“ 3 ”, 05
"4" for H, "5" for 06H, "6" for 07H, "7" for 08H, "8" for 09H, 0AH
Is "9" for 0BH, "A" for 0CH, "B" for 0CH, "C" for 0DH, "D" for 0EH, 0FH
In this case, the character "E" is displayed in the special symbol display area 50a as a special symbol.

(3) Middle stationary symbol designation code The middle stationary symbol designation code is an instruction code consisting of an operation number of 32H and 15 types of identification numbers of 01H to 0FH, and the identification number is the same as the left stationary symbol designation code. It has the same meaning as the identification number, and is used to display a character designated by each as a special symbol in the special symbol display area 50b. (4) Right stationary symbol designation code The right stationary symbol designation code is an instruction code consisting of an operation number of 33H and 15 types of identification numbers of 01H to 0FH, and the identification number is the same as the identification number of the left stationary symbol designation code. It has the same meaning, and is for displaying the character designated by each in the special symbol display area 50c as a special symbol. The variable time code, the left, middle and right stationary symbol designating codes are command codes that are transmitted almost simultaneously in two-byte units when a game ball fired on the game board 22 wins the ordinary electric accessory 36 as a starting port. And its contents are determined as follows.

As described above, the game ball is usually the electric accessory 3.
When the player wins No. 6, the value of the random number at the time, the value of the jackpot symbol random number, the value of the off symbol random number, and the value of the ordinary symbol random number are extracted. The extracted random number value is compared with the determination value “1” at the time of normal probability, and the determination value “1”, “3”, “5”, “7”, “9”, and “11” at the time of high probability.
If a match is found, a jackpot occurs, and if they do not match, a hit occurs. When a big hit occurs, a +1 is added to the extracted random number of the big hit symbol, and this value is used as the identification number of the left, middle and right still symbol designating code. That is, the identification numbers of the left, middle and right stationary symbol designating codes are the same. If they do not match and are out, the left, middle, and right stationary symbols are specified by adding +1 to each of the left symbol, middle symbol, and right symbol random values of the extracted symbol symbols. Code identification number. At this time, if the three identification numbers coincide with each other by accident, a process is performed in which the value of the identification number of the right stationary symbol designating code differs by a value “1”.

4. Big hit start Big hit start demonstration command code is special symbol display area 5
When displaying an image that appeals to the player that a big hit has occurred between the time when the big hit operation is started after the left, middle and right special symbols displayed on 0a to 50c display the same symbol. This command is used and consists of an operation number of 40H and an identification number of 01H. When the symbol control board 32b receives this instruction code, the LCD 3
On the screen 2a, characters such as "big hit" are displayed to display an image that makes the character happy, and a process of outputting a sound effect by the sound control board 35 is performed.

5. Jackpot Medium Jackpot Medium command is code before opening, code during opening, 1
It is classified into five commands of a 0 count winning code, a V passing code, and a round display code. (1) The pre-opening code is composed of an operation number of 50H and an identification number of 01H. When the symbol control board 32b inputs this command code, an image notifying the player that the special winning opening 40 will be opened is displayed on the background screen. The processing displayed on 52 is executed. (2) The open code is composed of an operation number of 50H and an identification number of 02H. When the symbol control board 32b inputs this instruction code, an image that informs the player that the special winning opening 40 is open is displayed. Execute the process to be displayed. (3) 10-count prize code is 50H operation number and 0
The main control board 30 is provided with a count switch 40b for detecting that a game ball has entered the special winning opening 40.
Alternatively, this command code is transmitted each time the signal is detected by the V switch 40a. When the symbol control board 32b inputs this command code, the value is incremented and the value is displayed on the background screen 52 each time the command code is input. As a result, the number display from zero to ten pieces is displayed on the screen every time a game ball wins in the special winning opening 40.

(4) The V passage code is composed of an operation number of 50H and an identification number of 04H. The main control board 30 detects by the V switch 40a that the game ball has passed through the special area in the special winning opening 40. Then, this instruction code is transmitted. When the symbol control board 32b inputs this command code, the character "V" is displayed in a large size on the screen to inform the player that the special winning opening 40 is closed and then opened again. (5) The round display code is composed of an operation number of 50H and an identification number of 05H.
Transmits this command code each time the device is opened again after the completion of the opening operation. When the symbol control board 32b inputs this command code, the value is incremented and the value is displayed on the background screen 52 each time the command code is input. This allows
The player is notified of the number of times the special winning opening 40 has been opened.

6. The big hit end command is a big hit end demonstration command code and a high probability shift command code. The jackpot end demonstration command code indicates that the game ball does not pass through the special area when the jackpot operation is completed, that is, when the big winning opening 40 has completed the opening operation 16 times, or when the opening is not continued up to 16 times. Command code sent when
It consists of an operation number of 60H and an identification number of 01H. When the symbol control board 32b inputs this command code, a message is displayed to inform the player that the big hit has ended. The high-probability transition command code consists of an operation number of 61H and 0
It consists of identification numbers from 1H to 02H. When the identification number is 01H, the high probability state continues, and the identification number is 02H.
Is the case where the high probability does not continue. This high-probability transition command code is transmitted to the main control board 3 as in this embodiment.
The transmission may be started from 0, or the symbol control board 32b may determine from the value of the image display command described above.

7. The operation abnormal operation command is an instruction command transmitted when an abnormality occurs in the pachinko machine 10. In this specific example, the command is based on the E1 error code of 70H01H, the E2 error code of 70H02H, and the E3 error code of 70H03H. It is configured.
In this specific example, the E1 error code is a ten-count abnormal error and is output when no game ball is detected when the special winning opening 40 is opened, and the E2 error code is a switch when the lower plate 23 is full and the tank is full. The E3 error code is output when the supply switch 44 is turned on. The error message displayed by transmitting these abnormal-time commands is erased by the 70H04H error release code transmitted when the abnormality is cleared.

Next, using the command code described above, L
The process of variably displaying a special symbol on the screen of the CD 32a will be described with reference to FIGS. Here, first, a process of determining (selecting) the basic variation pattern according to FIGS. 10 and 11 will be described. The microcomputer of the main control board 30 reads the result of the pass / fail judgment in step S180 of the main routine (step S300 in FIG. 10), reads the presence / absence of reach (step S310), and reads the presence / absence of time reduction (step S32).
0), a still symbol is read (step S330). The presence or absence of the reach is determined by whether or not the left stationary symbol and the middle stationary symbol coincide with each other even when an out-of-position symbol is displayed. When the random number value extracted using the reach random number is a predetermined value, the reach is determined. It may be configured to determine whether to execute the display. The time saving means that, in the high probability state described above, the fluctuation time of the left, middle, and right special symbols that are variably displayed in the special symbol display areas 50a to 50c is shortened as compared with the normal state. As described above, at the time of high probability, the ordinary electric accessory 36
Is extended, and the number of times of ordinary symbol determination results can be increased. As a result, when the probability is high, the number of winnings in the ordinary electric accessory 36 is increased, and the fluctuation time of the special symbol is also shortened. The derivation of the symbol determination result can be increased.

By executing the processing of steps S300 to S330, the result of the hit / fail judgment, the presence / absence of reach, the presence / absence of time saving, and each stationary symbol are read. In the subsequent processing, the basic fluctuations are performed in accordance with the read data. The pattern is determined (step S340), and the process returns to the return. As shown in FIG. 11, the determination of the basic variation pattern proceeds to the process of step S340 (STP
1) First, a jackpot (STP)
2) or out (STP3). In the case of departure, it is further assigned to reach (STP4) or no reach (STP5). Jackpot (STP
2) If it is assigned to either reach (STP4) or no reach (STP5) in the off state (STP3), it is assigned depending on whether or not there is a time saving (STP6 to STP11).

There is a time reduction of the big hit (STP2) (STP
6) is further sorted according to whether or not the specific symbol is the high-probability symbol according to the stationary symbol (STP12 to STP).
P13). Similarly, the time saving (STP7) of the jackpot (STP2) is further sorted by a stationary symbol depending on whether or not the specific symbol is the high-probability symbol (STP1).
4-STP15). Out of reach (STP3) reach (S
The time savings of TP4) (STP9) are further divided into two (STP16 to STP17) depending on whether or not the symbols are before and after the big hit symbol. Here, the symbols before and after the big hit refer to symbols whose right stationary symbol is close to the left and middle stationary symbols.

The STP 12 sorted by the above sorting process is the basic pattern 1 (STP 18),
P13 is basic pattern 2 (STP19), STP14 is basic pattern 3 (STP20), STP15 is basic pattern 4 (STP21), STP8 is basic pattern 5 (STP19).
TP22), STP16 is the basic pattern 6 (STP2
3), STP 17 is the basic pattern 7 (STP 24), S
TP10 is the basic pattern 8 (STP25), STP11
Corresponds to the basic pattern 9 (STP26). The basic pattern 1 (STP18) has a fluctuation time of 1 from the start of the change of the special symbol until each symbol stops and the special symbol is determined.
It is set to 0 seconds. Similarly, the basic pattern 2 (ST
P19) is 7 seconds, and basic pattern 3 (STP20) is 30
Second, basic pattern 4 (STP21) is 25 seconds, basic pattern 5 (STP22) is 8 seconds, basic pattern 6 (STP21).
23) is 20 seconds, basic pattern 7 (STP24) is 28 seconds
Second, the basic pattern 8 (STP25) is set to 7 seconds, and the basic pattern 9 (STP26) is set to 15 seconds. Note that these fluctuation times can be changed as appropriate.

The symbol control board 32b having received the image display command including the basic variation pattern executes a "display pattern selection routine" shown in FIG. When the microcomputer of the symbol control board 32b determines that the image display command has been transmitted from the main control board 30 (step S40).
0), the basic variation pattern and each static symbol are read from the command code (steps S410 to S420), the display pattern is sorted from the read data (step S430), and the process returns to the return. If no image display command is transmitted from the main control board 30 in step S400, the process returns to the return. FIG.
FIG. 3 is a schematic diagram showing a configuration in which each of the nine basic patterns of the basic variation pattern is divided into two or more display patterns.

FIG. 14 specifically shows a configuration for distributing a basic variation pattern consisting of nine basic patterns to two or more display patterns. The basic pattern 1 is a jackpot specific symbol, that is, “111”, “333”, “5”.
55 "," 777 "," 999 "," BBB "or" D
DD "is displayed, and there is a shortage of time.
In this basic pattern 1, each of the special symbol display areas 50a to 50a
When the special symbol determined according to the static symbol designating code is "1", the time of the variable display on the display region 50c starts to fluctuate on each display region at the same time, and then changes for 4 seconds on the display region 50a. Scrolled and displayed and stopped at the symbol "1", displayed on the display area 50b for 6 seconds, and displayed on the display area 50c and stopped for 10 seconds. Stationary with the pattern of.

When the static symbol of each special symbol is "D",
After starting to change simultaneously on each display area, the display area 50
a, the display is scrolled and displayed for 4 seconds and stopped at the symbol "D" on the display area 50b. The display is scrolled and displayed for 7 seconds on the display area 50b and stopped at the symbol "D".
It scrolls and displays for 0 seconds and stops at the symbol "D". When the static symbol of each special symbol is "3", the symbol starts to change simultaneously on each display area, and then scrolls and scrolls for 5 seconds on the display area 50a to stop at the symbol "3".
On the display area 50b, the image is scrolled and displayed for 7 seconds and stopped at the symbol "3". On the display area 50c, the image is scrolled and displayed for 10 seconds and stopped at the symbol "3".

When the static symbol of each special symbol is "7",
After starting the fluctuation on each display area at the same time,
That is, the scroll change display is performed with the same three-digit design, and after 10 seconds, the display is simultaneously stopped at the design of “7”. That is, in the basic pattern 1, the change start time and the change time on the display area 50c are made to be the same while the change time on the display areas 50a and 50b is different depending on the seven kinds of the same three-digit specific symbol. Is set. As a result, in the basic variation pattern 1, the display patterns are sorted into seven types according to the seven types of stationary symbols.

The basic pattern 2 includes non-specific symbols of jackpots, ie, “000”, “222”, “444”, “6”.
66 "," 888 "," AAA "," CCC "or" E "
EE "is displayed and there is a reduction in time.
In this basic pattern 1, each of the special symbol display areas 50a to 50a
When the static symbol of each special symbol determined according to the static symbol designating code is “0”, the variable display time on the variable symbol 50c starts changing on each display region at the same time, and then changes for 4 seconds on the display region 50a. The display is scrolled and displayed in a state of “0”, and the display is stopped at a pattern “0”. The display is scrolled and displayed in a display area 50b for 5 seconds, and the display is stopped in a pattern of “0”. Stationary with the pattern of.

When the static symbol of each special symbol is "E",
After starting to change simultaneously on each display area, the display area 50
On a, a scroll change display is performed for 4 seconds and the image is stopped at the symbol “E”. On the display region 50b, a scroll change display is performed for 6 seconds and the image is stopped at the symbol “E”.
It scrolls and displays for a second and stops at the symbol "E".
When the static symbol of each special symbol is "2", the symbol starts to change simultaneously on each display region, and then is scroll-variably displayed on the display region 50a for 5 seconds and stops at the symbol of "2", and the display region 50b Above, scroll change display for 6 seconds and "2"
, And is scrolled and displayed for 7 seconds on the display area 50c to stop at the symbol "2".

When the static symbol of each special symbol is "8",
After starting the fluctuation on each display area at the same time,
That is, the scroll change display is performed with the same pattern of the same three digits, and after seven seconds, the pattern is simultaneously stopped at the pattern "8". That is, in the basic pattern 2, the eight types of three-digit identical non-specific symbols are used.
The change start is set to be the same as the change time on the display area 50c, while the change time is different on the display areas 50a and 50b. As a result, in the basic variation pattern 2, the display patterns are divided into eight types by eight types of stationary symbols.

By the same processing as that for the basic patterns 1 and 2, the basic patterns 3 to 9 are also changed and the display area 50 is changed.
The display pattern can be divided into two or more so that the variation time on the display areas 50a and 50b is different due to the difference in the still symbol while the variation time on the c is the same.

According to the specific example described in detail above, in the same basic pattern, the special symbol display areas 50a to 50c
In the display area 50, the fluctuation time from the start of the change of the special symbol to the time when all the special symbols are stopped and fixed is the same.
The variation time on a and 50b can be assigned to two or more display patterns having different variation times in correspondence with the stationary symbols. Thereby, while reducing the number of basic variation patterns created on the main control board 30 and reducing the processing load, the number of display patterns in which the special symbols fluctuate on the screen of the LCD panel 32a is increased to display the special symbols. Can be varied in various ways. Also, the display patterns belonging to the same basic pattern have the same time from the start of the change of the special symbol to the determination of the special symbol. Therefore, when checking the performance of the machine based on the concept of the change time of the special symbol, the number of the basic change patterns is limited. Only has to be checked, and the test time can be shortened.

Next, a second specific example will be described with reference to FIGS. In the second specific example, a “display pattern selection routine” shown in FIG. 15 is used in place of the “display pattern selection routine” shown in FIG. 12 used in the first specific example, and FIG. 16 is used instead of the table in FIG. The other configurations are substantially the same as those of the first specific example. In the second specific example, when an image display command is transmitted from the main control board 30 (step S500), the basic variation pattern is read (step S51).
0), the value of the distribution random number FRND is extracted (step S520), the display pattern is distributed from the extracted random number value (step S530), and the process returns to the return. If no image display command has been transmitted from the main control board 30 in step S500, the process returns to the return. The distribution random number FRND is +1 every minute time.
When it reaches the maximum value of "99", it returns to "0" next time and is configured as a counter for repeatedly creating 100 integers from "0" to "99", and is executed by the microcomputer of the symbol control board 32b. When the process proceeds to this processing, the value is extracted. The timing at which the image display command is transmitted from the main control board 30 is unpredictable timing because it is related to the timing at which the gaming ball wins the ordinary electric accessory 36. Therefore, the distribution random number FRND, which is a counter, literally functions as a random number.

When the value of the sorting random number FRND is extracted, a display pattern is selected according to the chart shown in FIG. If the display patterns shown in FIG. 16 belong to the same basic pattern, the change time from the start of the change to the determination of all the special symbols is the same, but the display areas 50a and 50c
The above variable display is different. This distribution is performed according to the value of the extracted distribution random number FRND. At this time, if the value of the extracted distribution random number FRND is a predetermined value, a jackpot announcement is performed. The jackpot notice is
It means that a special symbol is displayed in advance to display a big hit symbol before it is determined with the same three digits. This jackpot notice is executed with a certain probability even in the case of a miss. Further, it is also possible to configure so that the reach announcement is executed based on the value of the random number FRND. The reach announcement refers to an advance notice of a reach state before the symbol in the display area 50b is stopped and fixed. This reach announcement is also performed with a certain probability even when the reach is not actually reached.

In the second specific example, the distribution of the display patterns is performed based on the value of the random number FRND. This allows
In addition to the effect similar to that of the first specific example, there is an effect that the display patterns can be made different even when the three static symbols have the same display mode without the display pattern being fixed by the static symbols. Also, there is an effect that the jackpot notice and the reach notice can be instructed and executed by the symbol control board 32b by the value of the random number FRND.
