The normal symbol display 7 will be described. The normal symbol display 7 is composed of a 7-segment display. Normally, the symbol display device 7 starts the operation of sequentially displaying a plurality of types of symbols one by one in response to the hitting ball passing through the passing port 13 and the passing ball detector 14 detecting the passing ball. . This variable display is stopped when a predetermined time has elapsed. When the variable display is stopped, if the symbol displayed on the normal symbol display 7 is a symbol of a predetermined type, the ball receiving member 9 of the variable winning ball device 8 is viewed from the front side. And moves outward, and the approach path for the hit ball of the variable winning ball device 8 is expanded. Thereby, the variable winning ball device 8
The probability that a hit ball will win is high. In order to distinguish the symbol displayed on the normal symbol display device 7 from the symbol displayed on the display unit 5 which will be described later, the symbol on the normal symbol display device 7 is called "ordinary symbol", and the display unit The design of 5 is called "special design".

In the present embodiment, the display unit 4 which is a "special symbol" is an LCD display, but not limited to this, it may be a mechanical display device such as a belt or a drum, or a CRT,
LED, fluorescent display tube, EL (electroluminescence),
It may be another electric display device such as plasma.
Further, the normal symbol display device 7 which is a "normal symbol" is not limited to the 7-segment display device and may be another display device described above. Further, one display device may be combined to display the "special symbol" and the "normal symbol".

Next, the variable winning ball device 8 will be described. When the hit ball is won in the variable winning ball device 8, the variation of the special symbol is started on the display unit 5. That is, the variable winning ball device 8 functions as a starting port for the variable display of the symbols on the display unit 5. The ball receiving member 9 provided in the variable winning ball device 8 is normally in a state in which the left part and the right part are closed and the approach path for hitting balls is narrowed. Then, the variable display of the normal symbol is performed, and as a result of the variable display, if the predetermined type of the regular symbol is stopped and displayed, in response thereto, the state where the left part and the right part of the ball receiving member 9 are opened. Then, the approach path of the ball is widened. As a result, it is easy for the hit ball to win the variable winning ball device 8, and the opportunity for the variable display of the special symbol to be displayed on the display unit 5 increases. Variable winning ball device 8
The hit ball which is won is detected by the starting ball detector 25.

The variable winning ball device 8 as a starting opening, which is one of the varying condition establishing means, is not a winning opening provided with a ball receiving member as in this embodiment, but a winning opening without a ball receiving member or a passage. You may comprise in a formula. In addition, the condition that the variation of the special symbol is started is not limited to the fact that the batting balls have won or passed through the specific winning opening and the passing opening, and each time a predetermined number (for example, 20) of batting balls are fired. You may make it materialize.

The start memory indicator 19 provided in the variable winning ball device 8 displays that the fact that the hit ball has passed through the passage port 13 is stored. If the hitting ball passes through the passage port 13, normally, when the predetermined time (0.002 seconds) elapses, the variable display of the normal symbol is displayed on the normal symbol display 7, but at that time, In response to the hitting ball having passed through the passing opening 13, when the variable display is already being performed on the normal pattern display 7, it is once that the hitting ball has passed through the passing opening 13. Remembered. Then, when the variable display of the normal symbol display 7 is stopped and the next variable display can be started, the variable display of the normal symbol is started based on the memory.

The start memory indicator 19 blinks when it is stored that the ball has passed through the passage opening 13. A maximum of four times the hit ball has passed through the passage opening 13 is stored. However, the starting memory indicator 19 is not configured to display the number of memories. The variable display of the normal symbol has a relatively small game value given to the player according to the display result, as compared with the variable display of the special symbol described later.
Therefore, it is extremely rare for the player to care about the number of times the ball hits through the passage opening 13 during the game. for that reason,
In this embodiment, the starting memory indicator 19 is configured to display only the presence / absence of the memory and not display the number of memories. As a result, the assembling cost of the start memory indicator 19 is reduced.

Next, the display section 5 will be described. The display unit 5 is composed of an LCD. When a hit ball is won in the variable winning ball device 8, a plurality of types of special symbols are variably displayed in each of the three regions of the left side, the center, and the right side on the display unit 5. When the combination of the three special symbols on the left side, the center, and the right side when this variable display is stopped becomes a predetermined specific combination, a "big hit" occurs. When a big hit occurs, the variable winning ball device 10 is in a favorable state for a player who is easy to win a ball from a state in which the ball is difficult to win a ball (hereinafter, this is referred to as a "second state"). (Hereinafter, this is referred to as “first state”). The state where the big hit occurs and the variable winning ball device 10 is in the first state is called the specific game state.

In addition to the variable display of the above special symbols, the display unit 5 displays the special symbols from the time the power of the pachinko gaming machine is turned on until the first ball hitting the variable winning ball device 8 is won. For example, when the variable display of the next special symbol is not displayed for a predetermined time after the variable display ends, to the player,
A demonstration screen for providing predetermined information or visually entertaining, a big hit screen for enhancing a game effect in a specific game state, and the like are displayed. Details of the display content of the display unit 5 will be described later with reference to other drawings.

At the time when the hit ball is won in the variable winning ball device 8, in response to the winning of the previous hit ball in the variable winning ball device 8, the variable display of the special symbol has already been performed on the display unit 5. When the specific game state is set based on the result of the variable display, the fact that the hit ball is won in the variable winning ball device 8 is temporarily stored. In the following description, the memory that the hitting ball has passed through the passage opening 13 is referred to as a “normal starting memory”, and the memory that the hitting ball is won in the variable winning ball device 8 is the “special starting memory”. Say. When there is a special start memory, the start memory indicator 6 is turned on. A maximum of four times is stored in the special starting memory. The start memory indicator 6 has four LEDs, and the number of LEDs among these four LEDs is turned on. Players are very interested in special starting memory not only with or without memory, but also with the number of memory. Therefore,
In this embodiment, the starting memory display 6 is configured to display not only the presence / absence of the memory but also the number of memories.

Here, the normal starting memory and the special starting memory will be described in more detail. As described above, when the hitting ball passes through the passage opening 13,
If the variation display of the normal symbol is already being performed in response to the fact that the ball has passed, the fact that the hit ball has passed through the passage opening 13 is stored as a normal start memory. In addition, at the time when the hit ball is won in the variable winning ball device 8, in response to the winning of the previous hit ball in the variable winning ball device 8, the special symbol is already being displayed in a variable manner, or the specific game. When it is in the state, the winning of the hit ball to the variable winning ball device 8 is stored as a special starting memory.

The normal starting memory and the special starting memory are stored in the RAM included in the control circuit 60 (see FIG. 2). Then, in the case of the normal starting memory, the variable display of the normal symbol display 7 is stopped, and when the variable display of the next time is ready to start, the predetermined storage area of the RAM is referred to, and the normal starting memory If there is, it is read and the variable display of the normal symbol for the next time is performed. Similarly, in the case of special starting memory, the variable display of the special symbol on the display unit 5 ends, and if the specific game state is based on the display result, the specific game state ends, and next. When the variable display of the special symbol can be started, the predetermined area of the RAM is referred to, and if there is a special start memory, it is read and the variable symbol of the next special symbol is displayed. Is performed.
These controls are performed by the basic circuit 26 in the control circuit 60.
(See FIG. 2) according to the game control program.
The configurations of the control circuit 60 and the basic circuit 26 will be described later.

The normal starting memory and the special starting memory are special in response to the passage of the preceding hitting ball, while the variable display of the ordinary symbol is being performed, and in accordance with the winning of the preceding hitting ball. It is not stored in the RAM only while the variable display of the symbols is being performed. When a hit ball passes through the passage port 13, it is always stored in the RAM once. Also,
When a hit ball is won in the variable winning ball device 8, it is always stored in the RAM once. However, if the variation display of the normal symbol and the variation display of the special symbol are not respectively performed at the time when the passing of the hitting ball and the winning of the hitting ball are stored, the memory is immediately read from the RAM and stored in the memory. Based on this, the process for performing variable display of normal symbols and variable display of special symbols is started. In this case, the memory that the ball has passed and the memory that the ball has won are read out from the RAM. In this way, not the memory that is immediately read and erased, but the memory that is read after the variable display of the normal symbol and the variable display of the special symbol that are being performed at that point are respectively, particularly, normally It is called a starting memory and a special starting memory.

Next, the variable winning ball device 10 will be described. As described above, the special winning ball device 10 is formed with the special winning opening 51. The special winning opening 51 can be tilted within a predetermined range in the front-back direction when viewed from the front side by the opening / closing plate 11,
Open or closed state. The opening / closing plate 11 is driven by a solenoid 21. Normally, the variable winning ball device 10 is in the second state in which the opening / closing plate 11 is closed and it is impossible to hit a ball at the special winning opening 51. Then, as described above, based on that the hit ball is won in the variable winning ball device 8, the variable display of the special symbol is performed on the display unit 5, and when the variable display ends, the predetermined special symbol If the combination of is displayed, a big hit occurs.
If a big hit occurs, the variable winning ball device 10 is the opening / closing plate 1
1 is tilted to the open state, and the first state in which a hit ball can win the special winning opening 51 is achieved.

The first state of the variable winning ball device 10 is 29.5 seconds after the opening / closing plate 11 is opened, or
The process ends when either of the 10 winnings in the special winning opening 51 wins, whichever comes first, and the opening / closing plate 11 closes to bring the variable winning ball device 10 into the second state.

Inside the special winning opening 51, a specific area (V pocket) is provided. When a ball hitting the special winning opening 51 wins this specific area, the winning ball is detected by the specific ball detector 24. In the following explanation,
A ball hitting a specific area is called a "specific prize ball", and a ball hitting a specific area is called a "V prize". When the specific winning ball is detected, the variable winning ball device 10 is driven and controlled again to the first state after the first state of the variable winning ball device 10 for that time is completed. This is called "repetitive continuous control". By this repeated continuation control, the variable winning ball device 10 is in the first state for 16 consecutive times at the maximum. In the following description, the first to sixteenth first operations that are repeated repeatedly are performed.
These states are referred to as the 1st to 16th rounds, respectively.

The 10-count display 12 provided in the variable winning ball device 10 displays the number of hit balls that have won in the special winning opening 51. As described above, 1 of the variable winning ball device 10
One of the two conditions for ending the first state of the times is that the number of winning balls in the special winning opening 51 reaches 10. By displaying the number on the 10-count display 12, the player is informed that the number of winning balls in the special winning opening 51 has reached 10.

With the structure of the game board 1 described above, a ball is hit into the game area 3 and flows from the upper part to the lower part,
When passing through the passage opening 13, the variable display of the normal symbol is started on the normal symbol display device 7. When the variable display of the normal symbol is stopped, if a predetermined type of normal symbol is displayed, the ball receiving member 9 of the variable winning ball device 8 is opened, and the variable winning ball device 8 is displayed. It is in a state where it is easy to win the ball. Further, if a hit ball is hit in the game area 3 and the hit ball wins the variable winning ball device 8, the variable display of the special symbol is started on the display unit 5. Then, at the time when the variable display of the special symbols is stopped, if a combination of predetermined specific special symbols is displayed, the opening / closing plate 11 of the variable winning ball device 10 is opened and the variable winning ball device is opened. 10
Changes from the second state to the first state. Variable winning ball device 1
When 0 becomes the first state, the big winning opening 51 for hitting balls
The winning rate for is significantly higher than in normal times. Furthermore, when the hit ball that has won the special winning opening 51 enters the specific area, the first state of the variable winning ball device 10 is continuously repeated. The player uses the pachinko gaming machine of this embodiment,

Next, referring to FIGS. 3 to 10, variable display of special symbols on the display unit 5 will be described.

FIG. 3 is an explanatory diagram showing the types and contents of random counters used to control the variable display of special symbols. The random counter is a means for counting random numbers by a program. In the pachinko gaming machine of the present embodiment, four kinds of random counters of random 1, 2, 3, 6 are used to control the variable display of special symbols. The value of these random counters is read at a predetermined timing during the pachinko game, and the variable display of the special symbol on the display unit 5 is controlled based on the value. Further, in FIG. 3, a variation of probability (described later) is used as the configuration of the modified example.
The contents of a random 7 for determining, a random 8 for selecting a type of a big hit screen (described later), and a random 9 for controlling display of a decorative pattern are shown.

Random 1 is a random counter for determining in advance whether or not the result of the variable display of the special symbol on the display unit 5 is a big hit. The procedure for determining in advance whether or not to generate a big hit will be described later with reference to FIG. Random 1 is incremented by 1 every 0.002 seconds in the range of "0" to "229".

Random 2 is a special symbol to be stopped and displayed in each of the three regions of the left side, the center, and the right side when it is previously determined that the result of the variable display of the special symbol on the display unit 5 is other than the big hit. It is a random counter for determining the type of. Random 2 is one counter, but on the basis of the value, three values for determining the special symbols to be stopped and displayed on the left side, the center, and the right side are individually determined. The values counted to determine the left, center, and right stop symbols are "0" to "1."
It is counted in the range of "4". Random 2 is incremented by 1 every 0.002 seconds and incremented by 1 at a predetermined cycle within the remaining time of the interrupt process.

The interrupt process mentioned here is an interrupt in response to the input of a reset signal for execution of the next time during execution of the game control main program (described later) at a certain time. Is generated, the execution of the program at that time is interrupted, and the program is re-executed from the beginning. The surplus time of interrupt processing is the time from the end of the operation according to each main processing instruction included in the main program until the reset signal for the next execution is input and an interrupt occurs. That is. Random 3 is to determine the procedure for variable display of the central special symbol to be stopped at the end by selecting from among multiple types when it is determined in advance that a reach will be generated during variable display of the special symbol. Is a random counter. In the present embodiment, the variation of the special symbols simultaneously starts in the left, center and right regions of the display unit 5. Then, when the predetermined time has elapsed, the variable display of each area is sequentially stopped in the order of left side, right side, and center. "Reach" means that the type of special symbols stopped on the left side and the right side are the same when the variable display on the left side is stopped and then the variable display on the right side is stopped, and the special symbol in the center is the same. If the symbols are stopped and displayed, a big hit occurs. As will be described later, there are four types of variable display procedures when the reach is established, that is, reach 1 to reach 4. Random 3 is counted up in the range of "0" to "7". The correspondence between the value of the random counter and the type of reach will be described later with reference to FIG. Random 3 count-up is 1 every 0.002 seconds,
The interrupt processing is performed one by one in a predetermined cycle within the remaining time.

Random 6 determines the contents of the fluctuating operation immediately before the fluctuating display of the central special symbol is stopped when the fluctuating display is controlled in advance in the procedure of reach 1 or reach 2. It is a random counter for.
In the reach 1 and the reach 2, the fluctuation speed is decelerated immediately before the fluctuation of the central special symbol is stopped. Random 6 determines how many symbols this deceleration display is performed. The value of Random 6 is counted up in the range of "0" to "5". If the value of the counter is "0" or "1", it is for 1 symbol, if the value is "2" or "3", it is for 2 symbols, if the value is "4" or "5", it is 3 symbols It is determined in advance that minute deceleration display is performed. Random 6 is incremented by 1 every 0.002 seconds and by 1 in a predetermined cycle within the extra time of the interrupt process.

Random 6 is, when it is determined in advance that the reach is established during the variable display of the special symbol, the procedure of the variable display of the central special symbol which is finally stopped is selected from a plurality of types. It is a random counter for determining. In the present embodiment, as will be described later, the variable display of the special symbol at the center when the reach is established is reach 1 to reach 4.
One of the four types is selected. Random 6 is counted up in the range of "0" to "5". The correspondence between the value of Random 6 and the type of reach will be described later with reference to FIG. Random 6 is incremented by 1 every 0.002 seconds and at regular intervals within the remaining time of the interrupt process.

Random 7, Random 8 and Random 9 described below are not used in the pachinko gaming machine of this embodiment, but will be described as a modified configuration.

Random 7 is a random counter for deciding whether or not to change the probability that the result of variable display of special symbols will be a big hit. Probability variation means varying the probability that the result of variable display of special symbols will be a big hit, based on the establishment of a certain predetermined condition. Random 7 is used to determine whether or not to perform this probability variation control. In the present embodiment, probability variation control is performed when the result of variable display of special symbols is a combination of predetermined symbols (described later), but random 7 is used to generate probability regardless of the content of the result of variable display. It may be modified so as to determine whether or not the variation control is performed.

Random 7 is counted up in the range of "0" to "2". If the value of the random 7 is "0", the probability that the result of variable display of the next special symbol will be a big hit is set high. As a result, the probability of being a big hit during the game is increased, and it becomes possible to give the player an interest in the game.

Random 8 is the result of variable display of special symbols,
It is a random counter for selecting the type of the big hit screen displayed on the display unit 5 when the big hit occurs and is in the specific game state. In the present embodiment, there is one kind of big hit screen, but for example, three kinds of big hit screens may be prepared, and any one of them may be modified by selecting a random value of 8. Random 8 is counted up in the range of "0" to "2". Random 8 is incremented by 1 every 0.002 seconds and by 1 in a predetermined cycle within the extra time of the interrupt process.

Random 9 is a random counter for selecting a decorative pattern. The pachinko gaming machine of the present embodiment does not have means for displaying a decorative design,
For example, a decorative design indicator may be provided on the game board 1 shown in FIG. The decorative pattern is not directly related to the control of the game, the game hall side, for example, according to the type of displayed decorative pattern, exchange the prize balls given during the specific game state for prizes. It is used when deciding whether to oblige that, or to allow the prize ball to be used for the game as it is.

The decorative pattern display is, for example, 6 LEs.
Construct using D. Numbers "1" to "6" are respectively assigned to these six LEDs, and the numbers are used as decorative designs. The variable display of the decorative pattern is performed at a predetermined timing during the variable display of the special symbol. The variable display of the decorative pattern is performed by sequentially lighting and displaying each one of the six LEDs. When the predetermined time has elapsed, the fluctuation of the lighting is stopped, and the number of the LED that is lit at that time is set as the stop decorative pattern. This stop decoration pattern is determined in advance by the value of random 9. The random number 9 is incremented in the range of "0" to "5". The counter values "0" to "5" correspond to the decorative symbols "1" to "6", respectively. Random 9 is incremented by 1 every 0.002 seconds and at regular intervals within the remaining time of the interrupt process.

In the pachinko gaming machine of this embodiment, the count-up of random 2, random 3, and random 6 is always performed once every 0.002 seconds in addition to the remaining time of the interrupt processing. In a conventional pachinko gaming machine, a random counter of this kind is counted up only within the extra time of the interrupt processing. Therefore, if there is no extra time or short time in the interrupt process, the random counter is not counted up, and, for example, the result of the variable display of the special symbol is the same between the previous time and this time, or for a long time. There was a problem that the reach was not established. Therefore, in this embodiment, random 1
Not only that, all of the random counters whose values are desired to be updated within a given time are at least 0.
It is configured so that it is incremented by one every 002 seconds. The 0.002 seconds is the length of the cycle in which the game control program including the subroutine program for counting up each random counter is periodically reset. Further, the random 8 and the random 9 used in the modified example are also surely incremented by 1 at least every 0.002 seconds. The count-up process of the random numbers 1, 2, 3, 6 will be described later with reference to the flowchart.

FIG. 4 is a flow chart showing a procedure for determining in advance whether or not a big hit will be generated based on the value of the random counter. Referring to the same figure, it decides beforehand whether the result of the variable display of the special design in indicatory department 5 is big hit or other than big hit, furthermore, the kind of stop design of the special design of left side, center and right side The procedure for determining will be described.

It is decided by judging the value of Random 1 whether to make a big hit or not to make a big hit. Random 1
If the value of “3” is “3”, it is determined in advance that it is a big hit. Also, when the random fluctuation control is being performed, if the value of Random 1 is any of "3", "5", "7", "11", and "13", it is a big hit, and if it is other than that, For example, it is decided in advance that it is not a big hit. The value of Random 1 can take 230 values from “0” to “229”. Therefore, when probability variation control is not performed, the probability of a big jackpot is 1/230, and when probability variation control is performed, the probability of a big jackpot is 5/230, which is five times the normal rate. .

When it is decided to be a big hit, subsequently, by determining the value of random 2, the type and arrangement of special symbols for generating a big hit are decided. When a big hit occurs, the count value for determining the special symbol on the left side of random 2 is used as a value for determining the types of all the special symbols on the left side, the right side, and the center. On the other hand, if it is determined in advance that it should not be a big hit, by subsequently determining the value of Random 2, the count value for each special symbol on the left side, the right side, and the center is read, and the left side And the type of stop symbol of the special symbol of the right side and the center is determined. In addition, in the case other than the big hit, the combination array of special symbols determined based on the three count values of random 2 happens to be a combination arrangement of the symbols that are big hits, in the middle of the special symbol. "3" is added to the count value for determining, and adjustment is forcibly made so that the variable display of the special symbol is stopped in the combination arrangement of the symbols.

FIG. 5 shows the values of random 2, the left side, the center,
It is explanatory drawing which shows the correspondence with the kind of stop symbol of the right special symbol. The special symbols include ten types of numerical symbols “0” to “9” and five types of character symbols “squid”, “crab”, “robot”, “Martian”, and “octopus”. Random 2 three values “0” to “9” for determining the types of symbols on the left side, the center, and the right side are “0” to numerical symbols.
Each corresponds to "9". Also, three values of Random 2 “10” to “14” are “squid” of the character design,
It corresponds to "crab", "robot", "Martian", and "octopus" respectively.

These 15 types of special symbols are variably displayed on the display unit 5, and the result of the variability display is that a big hit occurs if the stop symbols on the left side, the center, and the right side are all of the same type. In addition, when the big hit is a combination in which any three of the numerical symbols “3”, “5”, and “7” are arranged, the specific game state according to the occurrence of the big hit. And, from the time when the specific game state ends, the control of the probability fluctuation of the normal symbol is performed. These three numerical symbols “3”, “5”, and “7” are particularly referred to as “probability fluctuation symbol”.

Next, with reference to FIG. 6 to FIG. 10, control of variable display of special symbols on the display unit 5 will be described.

FIG. 6 is an explanatory diagram showing the types of changing states of special symbols. There are eight types of variation states A to H in the variation state of the special symbol. In the fluctuation state A, the symbols are variably displayed at a constant speed. In the fluctuation state B, the fluctuation speed is gradually decreased in 1.000 seconds to finally stop the fluctuation. In this fluctuation state B, fluctuations of three symbols are performed. In the changing state C, the symbol is changed at a constant speed for changing one symbol in 0.300 seconds. Fluctuating state D
Then, the fluctuation speed is gradually decreased in 0.400 to 1.200 seconds to finally stop the fluctuation. In the fluctuation state D, fluctuations of 1 to 3 symbols are performed. In the fluctuation state E and the fluctuation state F, as in the fluctuation state C, the symbol is changed at a constant speed at which a fluctuation of one symbol is performed in 0.300 seconds.

In the fluctuation state G, the fluctuation for one symbol is 0.1
The design is changed at a constant speed in 00 seconds. In the fluctuation state H, the fluctuation starts from the symbol before the two symbols in the symbol arrangement shown in FIG. 5 of the special symbol which is the target of the big hit, and the symbol is varied at a slow speed until the target special symbol is passed. It The fluctuation speed of the symbol at this time is a speed at which the fluctuation of one symbol is performed in 0.600 seconds. During the fluctuation display other than the slow fluctuation display, the symbols are changed at a high speed in which the fluctuation for one symbol is performed in 0.100 seconds.

FIG. 7 is a timing chart showing a control procedure of variable display of special symbols when a big hit is not generated and a reach is not established (hereinafter, referred to as "normal time"). When a hit ball is won in the variable winning ball device 8 (starting port in the figure), the winning ball is detected by the starting ball detector 25 (see FIG. 1).
). At the timing when the detection pulse rises, the values of Random 1 and Random 2 are extracted by the CPU of the basic circuit 26 (see FIG. 2) and stored in the RAM of the basic circuit 26.

Subsequently, the CPU executes the random 1 stored in the RAM at the falling timing of the detection pulse 0.002 seconds after the start winning of the ball hitting the variable winning ball device 8 is detected. The value is read, and based on the read value, it is determined in advance whether or not the result of the variable display of the special symbol is a big hit. The process of previously determining whether or not to make a big hit is performed by the procedure shown in FIG. At the same time as the reading of the value of random 1 and the determination processing, the CPU executes random 2
Read the value of. In the control procedure shown in the figure, it is determined in advance that the big hit is not generated by the determination of the value of Random 1, and the reach is not established by the three kinds of values of Random 2 (see FIG. 3). Determined in advance.

In normal time, the specific procedure for displaying the variation of the special symbols on the left side, the center, and the right side is as follows.
The basic circuit 26 determines the LC based on the determination result by the CPU.
The control command is sent to the D control circuit 33 (see FIG. 2), and the LCD
The control circuit 33 sends a display control signal to the LCD control board 34 (see FIG. 2) based on this control command. As a result, when 0.006 or 4.686 seconds have elapsed since the winning of the ball hitting the variable winning ball device 8 was detected on the display unit 5, the variation of the special symbols on the left side, the center, and the right side started at the same time. To be done.

The interval from the detection of a ball hitting prize to the start of the variation of the symbol is set to 0.006 seconds or 4.6.
Whether it is 68 seconds, if the previous variable display of the special symbol ends other than the big hit, the time when the variable display ends, and if the last variable display of the special symbol ends in the big hit , The time when the specific game state in response to the occurrence of the big hit is within 1 minute before the time when the winning of the hit ball is detected is determined. If any one of the above points is within 1 minute, the variation of the symbol is started when 0.006 seconds have passed, and if it is not within 1 minute, the variation of the symbol is started when 4.668 seconds have passed. It

The following two reasons are set for the time from the detection of the start winning to the start of the variable display of the special symbols. When performing the variable display of the special symbol based on the first start winning after the power of the pachinko gaming machine is turned on, the player hardly recognizes the variable display content of the special symbol. Even if the special symbols are variably displayed as they are, specially designed special symbols do not sufficiently exert the game effect due to the variability display, and rather make the player feel unsatisfied. Therefore, in the pachinko gaming machine of the present embodiment, when the variation display of the special symbol is performed based on the first starting prize after the power of the pachinko gaming machine is turned on, the variation display of the symbol starts more than other cases. The timing is delayed. An image showing information regarding variable display of special symbols is displayed at this delayed time. In the following description, the screen displayed at this time is referred to as a "pre-variation demonstration screen (simply" pre-variation demonstration screen ").

Also, at the time when the variable display of the special symbol for a certain number of times ends, or when the specific game state ends,
Even when there is no special starting memory, the start timing of the variable display of the special symbol is similarly delayed. In this case, the purpose is not to make the player recognize the contents of the variable display, but to aim at the effect of facilitating the player by facilitating the occurrence of the continuous variable display of the special symbols.
That is, by delaying the start timing of the variable display, the time required for the variable display becomes longer, and the start winning of the special symbol is more likely to be stored correspondingly. Moreover, since the time during which the symbols are actually displayed does not change, it is not necessary to separately improve the program for display control or to use multiple complicated program modules as the time changes. It is possible to prevent an increase in the assembly cost of the game machine as much as possible.

On the other hand, in the case where a hit ball is won in the variable winning ball device 8 within a predetermined time, or when there is a special start memory at the time when the variable display ends or the specific game state ends, No special processing is required for the player to recognize the contents of the variable display, and since the state in which the variable display is continuously performed has already occurred, it is not necessary to delay the start timing of the variable display. In this case, variable display is performed based on the fact that there is a special start memory when the variable winning ball device 8 has a start winning prize, or when the previous variable display ends or when the specific game state ends. When 0.006 seconds have elapsed from the time when the process was started, the variable display of the special symbols on the left side, the right side, and the center is started. In this way, in this embodiment, the timing of the variable display of the special symbol is switched according to the state of the pachinko gaming machine so that the gaming effect can be enhanced without waste.

For the special symbol on the left side, the display control of the variation state A is performed in 5.000 seconds after the variation is started. The fluctuation time in parentheses is the time when a shortened fluctuation (described later) is performed. At the time when 5.000 seconds have passed, the symbol before 3 symbols in the symbol arrangement of the symbol determined in advance by the value of Random 2 (hereinafter, “scheduled symbol”) is set at the stop position, and then the fluctuation The display control of the state B is performed. The display control of the variation state B is performed for 1.000 seconds, during which three symbols are varied, and finally the planned stop symbol is stopped and displayed.

For the special symbol on the right side, the display control of the variation state A is performed in 6.000 seconds after the variation is started, and subsequently, the display control of the variation state B is performed in 1.000 seconds. Done. In the fluctuation state B, similarly to the fluctuation display on the left side, the symbol before the three symbols of the planned stop symbol is set to the stop position, and then the fluctuation of the three symbols is performed in 1.000 seconds, and finally the planned stop. The design is stopped and displayed.

For the central special symbol, the display control of the variation state A is performed in 7.000 seconds after the variation is started, and subsequently, the display control of the variation state B is performed in 1.000 seconds. Done. In the fluctuation state B, similarly to the left and right fluctuation displays, the symbol before the three symbols of the planned stop symbol is set at the stop position, and then the three symbols are varied, and finally the planned stop symbol. Is stopped.

FIGS. 8 and 9 are timing charts showing the control procedure of the variable display when the reach including the final big hit (hereinafter “big hit”) is established (hereinafter “reach”). is there. It should be noted that, during the reach time, the time when the reach that does not generate the big hit is finally established is referred to as the “outside reach time”.

Referring to FIG. 8, at the time of reach, the winning of the hit ball to the variable winning ball device 8 is detected, and at the timing when the detection pulse rises, by the CPU of the basic circuit 26,
Random 1 and random 2 values are extracted and stored in the RAM.

Subsequently, the CPU reads the value of random 1 stored in the RAM 0.002 seconds after the start winning is detected and at the timing of the fall of the detection pulse, and based on the read value. , It is determined in advance whether or not the result of the variable display of the special symbol is a big hit. Furthermore, CP
U reads the value of random 2. The above procedure is the same as the normal control procedure shown in FIG. 7.

At the time of reach, the following processing is further performed 0.002 seconds after the start winning is detected. CPU
Is a case where it is determined in advance that a big hit will be generated by judging the value of Random 1, and 3 of Random 2 read out.
Random 3 and random 6 values are extracted when the type value indicates that the reach is established. Furthermore, the random 7, the random 8, and the random 9 used in the modified example described with reference to FIG. 3 are extracted at this timing.

Then, the variable display of the special symbols on the left side, the right side, and the center is started all at once. The fluctuation display is started at a time 0.006 seconds or 4.686 seconds after the start winning detection pulse rises, as in the normal time. The control procedure of the variable display on the left side and the variable display on the right side at the time of reach is the same as the procedure at the normal time.

Referring to FIG. 9, the variable display at the center at the time of reach will be described. There are four types of reach display procedures, reach 1 to reach 4. Any one of these four types of reach is selected by the value of Random 3. If the value of random 3 is “0”, reach 1 is selected. Random 3 value is "1" or "2"
If so, reach 2 is selected. If the value of Random 3 is “3” or “4” or “6”, Reach 3 is selected. If the value of the random 3 is “5” or “7”, the reach 4 is selected. In any of Reach 1 to Reach 4, after the variable display is started, 7.
The display control of the variation state A is performed for 000 seconds, and 7.0
At the time when 00 seconds have passed (at the time of “C” in the figure), a symbol of the same kind as the special symbol which is stopped and displayed on the left side and the right side to establish the reach is set at the stop position. At the time point c, the variable display on the left side has already stopped as shown in FIG. 8, and subsequently, the variable display on the right side has stopped. During the shortening fluctuation, the period of the fluctuation state A is shortened to 3.600 seconds.

Each control procedure of the reach 1 to the reach 4 after the time point c will be individually described. In the reach 1, the display control of the variation state C is performed in the subsequent 4.800 to 13.800 seconds. In the fluctuation state C, fluctuations of 16 to 46 symbols are carried out at a constant speed for fluctuation of one symbol in 0.300 seconds. Next, from the time when the symbols 1 to 3 symbols before in the symbol array of the planned stop symbol are set to the stop position, the display control of the fluctuation state D is switched to reduce the fluctuation speed. The value of Random 6 determines how many symbols out of 1 to 3 symbols to start decelerating. The variation of 1 to 3 symbols is 0.400 depending on the number of symbols determined
1. It is carried out for 200 seconds, and finally the planned stop symbol is stopped and displayed.

In the reach 2, the display control of the changing state E is performed for 4.500 seconds from the time point C. Fluctuating state E
In the case, the variation for 15 symbols is performed at a constant speed for performing the variation for 1 symbol in 0.300 seconds. After that, the display control of the variable state F is performed. In the fluctuation state F, as in the fluctuation state E, a fluctuation of one symbol is performed in 0.300 seconds at a constant speed of 4.800 to 9.300 seconds for 16 to 3
The variation for one symbol is performed.

Thereafter, as in the case of the reach 1, the display control of the variable state D is switched from the time when the symbol before any one of the symbols 1 to 3 of the scheduled stop symbol is set at the stop position. The deceleration control is started. The number of symbols before which the deceleration control is started is determined by the value of the random 6 as in the case of the reach 1. If the value of Random 6 is "0" or "1", it is from one symbol before, if the value is "2" or "3", it is from 2 symbols before, and the value is "4" or "5". For example, the deceleration control is started from three symbols before. In the fluctuation state D, the fluctuation speed is gradually slowed in 0.400 to 1.200 seconds, and fluctuations are made only for the symbols determined by the value of the random 6 out of 1 to 3 symbols, and finally planned. Stop the fluctuation with the stop symbol displayed.

In Reach 3, from the time of C, the fluctuation state E
Display control is performed. Change of one symbol 0.300
The fluctuation of 15 symbols is 4.5 at a constant speed in a second.
It is performed in 00 seconds. After that, display control is performed in which fluctuation and pause are repeated. First, the display control of the variation state G is performed in 1.300 seconds. In the fluctuation state G, the fluctuation for one symbol is changed for 13 symbols at a constant speed for 0.100 seconds. Next, the fluctuation of the design is 0.
Paused for 400 seconds. Next, the fluctuation state G again
The display control of is performed in 1.600 seconds, and the variation for 16 symbols is performed. After that, the fluctuation is temporarily stopped again in 0.400 seconds. After that, the display control of the fluctuation state G is performed again in 1.600 to 1.700 seconds,
After the fluctuation for 17 symbols, the fluctuation is stopped in the state where the planned stop symbol is finally stopped.

In the reach 4, the display control of the variation state E is performed from the time of C, and the variation of 15 symbols is performed in 4.500 seconds. After that, the display control of the fluctuation state H is performed, and after 44 to 45 symbols are changed in 6.900 to 7.500 seconds, the change is finally stopped while the planned stop symbol is displayed. To be done.

As described above, in the pachinko gaming machine of the present embodiment, at the time of reach, any one of a plurality of control procedures of reach 1 to reach 5 is randomly selected and executed. Therefore, the player can play an interesting and rich game as compared with the case where the same control procedure is repeated every time the reach is established as in the conventional case.

In Reach 1 and Reach 2, the timing to start deceleration immediately before the variable display is stopped is selected at any time by the value of the random counter.
In conventional pachinko game machines, the timing of deceleration is uniform. Therefore, when the player becomes accustomed to the pachinko gaming machine, he / she can predict the stop symbol by looking at the type of symbol displayed when deceleration is started, and reduce the fun of the game. It was the cause. On the other hand, if the timing to start deceleration is varied in various ways as in this embodiment, the player cannot predict the stop symbol before the fluctuation stops, so the expectation for the occurrence of a big hit until the fluctuation completely stops. Can be held by the player.

Further, in the reach 2, the reach 3, and the reach 4, when the display control of the variable state E is performed, the background of the display screen is switched from one type to another type, as will be described later, so that the player Give a visual stimulus to
I try to improve the game effect.

FIG. 10 (A) is a timing chart showing the time relationship between the end of the variable display of the special symbol and the opening / closing of the special winning opening 51. The variable display of the special symbol is started, the symbol on the left is stopped, then the symbol on the right is stopped, and finally the symbol in the center is stopped, and when the variable display is finished, the combination of the stopped symbols is changed. To be judged. If the combination of the stop symbols is a big hit with three special symbols of the same type, the special winning opening 51 will be in the open state when 5.000 seconds have elapsed from the end of the variable display. Whether the special winning opening 51 is open for 29.500 seconds,
Alternatively, the process ends when one of the 10 winning balls in the special winning opening 51 wins, whichever comes first. Also, if there is a V prize when the special winning opening 51 is in the open state, it will be 2. after the open state of that time is finished.
When 000 seconds have passed, the special winning opening 51 is opened again.

FIG. 10B is a timing chart showing the time relationship between the opening / closing of the special winning opening 51 and the start of the variable display of the special symbol for the next time. 12.500 seconds or 10.500 seconds if there is a special starting memory (described above) at the time when the special game state of a certain number of times ends and the special winning opening 51 that has been in the open state is closed. When the second has elapsed, the processing for performing the next variable display based on the starting memory is started. 12.500 seconds and 1
Which time of 0.500 seconds has elapsed to start the processing is determined by the special winning opening 51 during the specific game state of that time.
It is determined by whether or not a hit ball is won. At least one batting ball is the special winning opening 51 during the specific game state of that time.
In the case of winning the prize, the process is started when 12.500 seconds have passed. Further, if no hitting ball is won in the special winning opening 51 during the particular game state of the time, 1
The process starts when 0.500 seconds elapses. When the process is started, the values of random 1 and random 2 are extracted and stored in the RAM.

After that, when 0.002 seconds have passed, that is, 12.502 seconds or 10.502 seconds have passed since the special winning opening 51 was closed, the reading of the value of random 1 and the determination processing are performed, Furthermore, the value of Random 2 is read. Extraction, storage, reading, determination, etc. of these values of Random 1 and Random 2 are performed in response to the rising edge and the touch falling edge of the detection pulse of the ball hitting the variable winning ball device 8 shown in FIGS. 7 and 8. Correspond. Then, when 0.004 seconds have elapsed, that is, when the processing of the next time has started, 0.006 seconds have elapsed, the special symbol of the next time (only the left side in the figure) starts changing. .

FIG. 10C is a timing chart showing the time relationship between the end of the variable display of the special symbol for one time and the start of the variable display of the special symbol for the next time. Variable display is started a certain number of times, the symbol on the left stops, then the symbol on the right stops, and finally the symbol in the center stops, and when the variable display ends, the combination of stop symbols Is determined. At that time, if there is a special start memory (described above), when 0.500 seconds or 3.120 seconds have elapsed, processing for performing the next variable display based on the start memory is performed. Be started. Which time of 0.500 seconds or 3.120 seconds has elapsed to start the processing is determined by the type of the procedure of the variable display at that time.
When the variable display at that time is performed in the normal procedure or the reach 1 procedure, the process is started when 0.500 seconds elapse. Further, when the variable display at that time is performed by any one of the reach 2, 3 and 4, the processing is started when 3.120 seconds have elapsed.
When the process is started, the values of random 1 and random 2 are extracted and stored in the RAM.

Thereafter, when 0.002 seconds have passed, that is, 0.502 seconds or 3.122 seconds have passed from the determination processing of the combination of the stop symbols, the reading of the value of Random 1 and the determination processing are performed, Furthermore, the value of Random 2 is read. Extraction, storage, reading, determination, etc. of the values of these random 1 and random 2 are described in FIG. 7 and FIG.
It corresponds to the processing in response to the rising and falling of the detection pulse of the ball hitting the prize in the variable winning ball device 8 shown in FIG.
Then, when 0.004 seconds elapses further, that is, when 0.006 seconds elapses after the next round of processing is started, fluctuation of the symbol on the left side of the next round is started.

As described above, in the pachinko gaming machine of this embodiment, when the variable display of the special symbol is continuously performed based on the special starting memory, the next time is displayed from the time when the previous variable display is finished. The interval until the start of variable display is lengthened or shortened depending on the type of control procedure of the previous variable display. In normal time (other than reach) or reach 1, the content of the control procedure does not differ from the conventional one, so that the next round of processing is started when a relatively short 0.500 second has elapsed. On the other hand, the contents of the control procedure of the reach 2, 3 and 4 are variously devised to enhance the game effect as shown in FIG. In order to fully bring out the effects of these measures, the relatively long length of 3.120
When the second elapses, the next processing is started.

Next, with reference to FIG. 11 to FIG. 15, the variation of the normal symbol will be described. FIG. 11 is an explanatory diagram showing a display mode of a normal symbol. Ordinary symbol display 7 is 7
It is configured using a segment display. By the 7-segment display, as a normal symbol, "0" to "9",
1 of "A", "J", "P", "H", "L", "-"
Six types of symbols are displayed in order. The display time for one symbol is 0.064 seconds, and the time for one cycle to finish displaying all 16 types of symbols is 1.024 seconds.

FIG. 12 is an explanatory diagram showing the types and contents of random counters used to control the display of ordinary symbols. As a random counter for ordinary symbols, a random number 4 for determining in advance whether or not the result of the variable display of the ordinary symbol is a hit, and a random number 5 for determining a scheduled stop symbol of the result of the variable display There is. Random 4 is incremented by 1 every 0.002 seconds in the range of "3" to "12". Further, the random number 5 is counted up in the range of "0" to "15" by 1 every 0.002 seconds and by 1 at a predetermined cycle within the remaining time of the interrupt processing. It should be noted that, in addition to incrementing the count of Random 4 by 1 every 0.002 seconds, it may be modified so as to increment by 1 at a predetermined cycle within the remaining time of the interrupt process.

Conventionally, a random counter for determining a scheduled stop symbol of a normal symbol, such as Random 5, has been counting up exclusively within the remaining time of the interrupt process. Therefore, if the remaining time of the interrupt process is short or not at all, the value of the random counter is not updated, and the monotonous game state that the results of multiple consecutive variable displays are the same type of symbol There was a possibility that it would occur. Therefore, in this embodiment, the random number 2 for the special symbol described above is used.
As with 3, 6 also for random 5 for normal symbols,
With the count-up within the remaining time of the interrupt processing, 0.
Every 002 seconds, the count is always incremented by one.

FIG. 13 is an explanatory diagram showing the correspondence relationship between the value of Random 5 and the type of scheduled stop symbol of the ordinary symbol. The value of Random 5 determines the planned stop symbol of the normal symbol. Random 5 values "0" to "15", normal symbols "0" to "9", "A", "J", "P", "H",
"L" and "-" are associated with each other.

FIG. 14 decides in advance whether or not the result of the variable display is hit based on the value of Random 4, and further determines the scheduled stop symbol of the result of the variable display based on the value of Random 5. It is a flow chart which shows the procedure to do. If the value of Random 4 is "3" out of "3" to "12", it is determined in advance that the result of the variable display of the normal symbol is a win. If the value of Random 4 is other than "3",
It is decided in advance that it will not be a hit.

Further, when the probability change control is in the high probability state, the value of random 4 is "3" to "12".
In the case of "3" to "11", it is determined in advance that the result of the variable display of the normal symbols is a win, and if the value of Random 4 is "12", it may be other than the win. Determined in advance. At the time of the normal probability that the probability fluctuation control is not performed, the probability that the result of the variable display of the normal symbol is a hit is 1/10. In addition, at the time of high probability that probability change control is performed, the probability that the result of the variable display of the normal symbol is a hit is 9/10, which is nine times that at the time of normal probability.

If it is determined in advance whether to win or not to win, then, using the value of Random 5, the type of ordinary symbol that is finally stopped and displayed when the variable display is finished To decide. If you do not hit,
The value of random 5 is extracted, and the normal symbol (see FIG. 13) corresponding to the value is set as the scheduled stop symbol of the normal symbol. At this time, when the winning symbols “3”, “5”, and “7” are accidentally selected by the extracted values, the symbols “4” and “6” corresponding to the respective next values are selected. , "8"
Select to force the planned stop symbol to be a symbol other than the hit symbol.

The scheduled stop symbol is determined by using a value of Random 5 also in the case of winning. However, in the case of a hit,
The value of Random 5 and the types of scheduled stop symbols are associated with each other as follows. If the value of Random 5 is "0" to "4", the symbol "3" is selected as the scheduled stop symbol. Also,
If the value is "5" to "9", the symbol "5" is selected. Furthermore, if the value is "10" to "15", "7"
Is selected.

FIG. 15 is a variation display of the ordinary symbol and the passage opening 1
Passing the ball of 3 ("Ordinary symbol gate" in the figure),
It is a timing chart which shows the time relation with opening / closing of the variable winning ball device 8 ("normal electric accessory" in the figure), and the procedure of probability variation control.

FIG. 15 (a) is a timing chart showing the time relationship between the fluctuation / stop of the ordinary symbol and the passage of the hitting ball at the passage opening 13 (ordinary symbol gate). When the hit ball passes through the passing port 13, the passing ball is detected by the passing ball detector 14 (see FIG. 1). At the timing when the detection pulse rises, the value of Random 4 is extracted by the CPU of the basic circuit 26 (see FIG. 2), and the RAM of the basic circuit 26 is extracted.
Stored in.

Subsequently, the CPU reads and determines the value of random 4 stored in the RAM and determines the random 5 when 0.002 seconds have passed after the passing ball was detected.
The value of is extracted, and at the same time, the fluctuation of the normal pattern is started. The CPU reads the value of Random 4 stored in the RAM, and based on the read value, determines in advance whether or not the result of the variable display of the normal symbols is a hit.
Further, the CPU extracts a value of Random 5 and determines a scheduled stop symbol based on the value. The process of determining whether or not to win and the planned stop symbol in advance is shown in FIG.
The procedure shown in FIG.

After the variation of the normal symbol is started, 16
The types of symbols are sequentially changed at a constant speed of 1.024 seconds per cycle. And after 25,000 seconds have passed,
The fluctuation is stopped when the planned stop pattern is displayed. Two
The time from the time when 5.000 seconds elapses until the fluctuation stops takes 0 to 0.960 seconds depending on the type of the planned stop symbol.

FIGS. 15 (b) and 15 (c) show the variation / stop of the ordinary symbol and the opening / closing of the variable winning ball device 8 (ordinary electric accessory).
It is a timing chart which shows a time relation with closure.
(B) shows the procedure at the normal probability, and (c) shows the procedure at the high probability.

Referring to FIG. 10B, when the variation of the normal symbol is stopped, the type of the stopped symbol is checked. When the stop symbol is any of the symbols "3", "5", and "7", the ball of the variable winning ball device 8 is 0.002 seconds after the fluctuation is stopped. The receiving member 9 (see FIG. 1) rotates outward when viewed from the front side,
The entry path of the ball for hitting the variable winning ball device 8 is widened to be in an open state. The variable winning ball device 8 is opened for 0.500 seconds, and then the ball receiving member 9 rotates inward as viewed from the front side, and the approach path of the ball for hitting the variable winning ball device 8 is narrowed and closed. Becomes After that, the hit ball passes through the passage opening 13 again and the variable display of the normal symbol is performed, and the variable winning ball device 8 is closed until a hit occurs. On the other hand, if the variable winning ball device 8 is in the closed state and there is a normal starting memory, the value of Random 4 is extracted and stored at the time of the closed state, and 0.002 seconds have passed thereafter. At this time, the reading and determination of the value of random 4 stored and the extraction of the value of random 5 are performed, and at the same time, the variable display of the normal symbol for the next time is started. When the variable display result value is generated, the above-described procedure is repeated.

Referring to FIG. 10C, at a high probability, the variable winning ball device 8 is opened at the time when 0.002 seconds elapses after the fluctuation of the normal symbol is stopped. The open state is
It continues for 2.800 seconds and then closes for 7,000 seconds. After that, the variable winning ball device 8 is opened again, the open state is continued for 2.800 seconds, and then the variable winning ball device 8 is closed. In this way, at a high probability, the variable winning ball device 8 is opened twice for 2.800 seconds with the closed state for 7.000 seconds interposed between them. The probability of winning the ball device 8 is significantly increased. The procedure after the second open state of the variable winning ball device 8 is completed is the same as that in the normal probability. FIG. 15D is a timing chart showing the procedure of the probability variation control. The condition device shown is
It is the display unit 5 (see FIG. 1). The operating state of the condition device is a state where a big hit occurs as a result of the variable display of the special symbol on the display unit 5, and in response thereto, the big hit demonstration screen in the specific game state is displayed. The start time of the two operating states shown is the time when the display result of the variable display of the special symbol is derived. The special symbol is variably displayed on the condition device (display unit 5), and the display result is a combination of big hit symbols in which any one of the symbols "3", "5", and "7" is prepared. If it is, a specific game state due to the occurrence of the big hit (conditional device operating state)
Probability change control is started from the time when is finished, the probability that the result of the variable display of the normal symbol is a win and the probability that the result of the variable display of the special symbol is a big hit are high probability states. Stochastic fluctuation control ends when the result of the variable display of the special symbols on the display unit 5 is subsequently generated by the combination of the jackpot symbols having three symbols other than "3", "5", and "7". To do.

Next, with reference to FIGS. 16 to 20, a screen display example of the display unit 5 will be described.

16 (a) to 16 (g) and FIG. 17 (a).
~ (G), after the power of the pachinko gaming machine is turned on,
It is a screen configuration diagram showing a display example of the screen until the variable display of the special symbol is performed in response to the ball hitting the variable winning ball device 8 first, and the variable display ends. From the time when the power is turned on to the time when the variable display of the special symbol in response to the winning of the first hit ball on the variable winning ball device 8 is started, the normal demonstration shown in FIG. A screen (hereinafter referred to as "normal demo screen") is displayed. A message for introducing the content of the story displayed on the display unit 5 is displayed as a telop on the normal demo screen.

After that, when the winning of the hit ball to the variable winning ball device 8 is detected, the demonstration screen before the fluctuation of the special symbols shown in FIGS. Screen)) is displayed. In this embodiment, as shown in the figure, a story is displayed in which the Earth is attacked by a mysterious UFO Corps and the Earth Army battles with the UFO Corps to defend the Earth. First, the screen of FIG. 16 (b) showing a scene in which a fighter takes off from the Earth Army base is displayed, and then the screen of FIG. 16 (c) showing a scene in which a fighter flies in the sky is displayed.

16D to 16G displayed thereafter.
17 (a) to 17 (g) are screens (hereinafter referred to as "design fluctuation screens") for variably displaying special symbols. As shown in FIG. 16D, in the symbol variation screen,
First, the image of the scene where the fighter flies is used as a background, and at the position where the fluctuation of the special symbol stops, the initially set symbol is displayed. UFO showing the design following the initial design design
An image is displayed showing the scene of the legion flying from here to the other side.

Next, as shown in FIG. 16 (b), the variation of the special symbol is started. The variation of the special symbol of this embodiment,
The variation of the special symbol is displayed by displaying the scene where the UFO with the special symbol flies from the other side to here on each of the left side, the center and the right side of the screen. The fluctuation of the pattern starts simultaneously on the left side, the right side, and the center. When it comes time to stop the movement of the special symbols on the left side, the right side, and the center, a missile will be launched from a fighter of the Earth Army and destroy the corresponding UFO. When the UFO is destroyed, the special symbol attached to the UFO is displayed at the stop display position of the symbol. FIG. 16 (f) shows a state in which the UFO on the left side has been destroyed and the special symbol “7” is stopped and displayed.

Then, when the timing to stop the fluctuation of the right special symbol comes, a missile is launched from the fighter to the right UFO, and the right UFO is destroyed as shown in FIG. 16 (g). The special symbol is displayed at the stop position. After that, as shown in FIG. 17A, the UFO in the center is
Only the scene where only the flying is displayed, and when the timing to stop the fluctuation of the special symbol in the center comes, similarly, the missile is launched from the fighter and the UFO in the center is destroyed,
As shown in FIG. 17B, the central special symbol is displayed at the stop position. At this point, the combination of the stop symbols of the three special symbols on the left side, the right side, and the center is determined. If this stop symbol combination is a combination of symbols of the same type, a big hit occurs. When a big hit occurs, Fig. 17
As shown in (c), the image of "FEVER" is further added and displayed.

FIGS. 17A to 17C described above are display examples of screens corresponding to the display control of the reach 1. Next, a display example of a screen corresponding to the display control of the reach 2, 3 and 4 will be described with reference to FIGS. In addition,
The screen display examples until the reach is established are as shown in FIGS. 16 (a) to 16 (g) as in the case of the reach 1. FIG. 17
(D) is the variation state E of the reach 2, 3, 4 shown in FIG.
7 is a screen displayed when the display control of is started.
When the reach is established, the background image on the screen is changed from the image 101 representing the earth space to the image 1 representing the outer space.
Scroll to 03. And in FIG.
As shown in (e), in the state where the image 103 of outer space is in the background, a state in which only the central UFO fluctuates is displayed, and as shown in FIG. 17 (f), at a timing when the symbol is stopped and displayed. The UFO is destroyed, and the stop symbol of the special symbol in the center is decided. At this point, 3 on the left, right and center
When the combination of the two stop symbols is confirmed and a big hit occurs, as shown in FIG. 17 (g), the image of “FEVER” is additionally displayed.

FIG. 18 is a schematic diagram for explaining the structure for switching the background image from the image 101 of the earth space described above with reference to FIG. 17D to the image 103 of the outer space. In the pachinko gaming machine of this embodiment, an image display control circuit is included inside the LCD control board 34 (see FIG. 2) controlled by the display unit 5. The basic configuration of the image display control circuit is not different from the conventional one, and thus the illustration is omitted. The image display control circuit is a VRAM (Video Rand) for temporarily storing image data to be displayed on the display screen.
om Access Memory) is included. The image data stored in this VRAM is read and displayed on the screen. FIG.
Reference numeral 8 denotes an area for storing the data of the image displayed as the background during the variable display of the special symbol. The area delimited by the alternate long and short dash line corresponds to the storage area of image data displayed on one screen.

As shown in the figure, in the present embodiment, image data of three screens for storing the background image, that is, data having a capacity three times as large as the image data which can be simultaneously displayed on the display unit 5 is stored. The size is memorable. In this storage area, the data of the image 101 of the earth space and the data of the image 103 of the outer space are stored together, and before the reach is established, the data of the image 101 of the earth space at the bottom of the figure is read out. When the reach is established, the read area of the image data is gradually moved to the upper part in the figure and the background image is scrolled. Finally, the image data in the upper part of the figure is read out and displayed on the screen as a background image. In this way, by storing the background image in a storage area having a larger capacity than the storage area of the image data for one screen and gradually moving the reading area as necessary, as shown in FIG. 17D. In addition, the background portion of the screen can be smoothly changed to provide a realistic image display.

FIG. 19 is a screen configuration diagram showing a display example of a demonstration screen (hereinafter referred to as "big hit demonstration screen") displayed during a specific game state after a big hit has occurred. As shown in FIG. 19 (a), the jackpot demonstration screen displays an image representing the type of the combination symbol of the jackpot this time in the upper left portion, and the upper right portion of the screen in the particular game state during that round. A numerical image is displayed for displaying the number of hit balls that have won the special winning opening 51, and a graph image for analog-displaying the number of special winning balls is displayed at the upper center of the screen. At the bottom of the screen, the image of the Earth Army fighter continues to be displayed. Then, when a predetermined time has elapsed, a light image is displayed in the center of the screen.

After that, as shown in FIG. 19B, the image of the light in the center is switched to, and the image of the character "1 ROUND" representing the first round is displayed. Is displayed. Then, in FIG.
As shown in (c), the image of the character representing the round is erased, and the scene in which the enemy character attacks the fighter is displayed. If there is a V prize while this screen is displayed, as shown in FIG. 19D, a scene in which a fighter launches a missile and destroys the enemy character is displayed. This allows the player to know that the V prize has been won. Further, the images of numbers and the graph images for displaying the number of big winning balls in FIGS. 19C and 19D show examples in which the numbers of big winning balls won at that time are displayed. . By displaying these images, the player can easily know the number of special winning prizes.

FIG. 20 is a screen configuration diagram showing a display example of a demonstration screen (hereinafter referred to as "big hit end demo screen") displayed from immediately before the specific game state ends to when it ends. V in each round from 1st to 15th
If there is a winning and the repeat continuation control proceeds to the next round in sequence and the final 16th round is completed, FIG.
The screen shown in (a) is displayed. As a story,
If you reach the final round, you will win the Earth Army side,
A message to that effect is displayed on the screen. continue,
As shown in FIG. 20B, an image of "THE END" indicating the end of the story when the final round is reached is displayed.

On the other hand, in any one of the first to fifteenth rounds, 29.5 seconds have passed without V winning or the number of winning balls to the special winning opening 51 has reached 10,
When the round ends, the specific game state ends at that point. In this case, as shown in FIG. 20C, a scene in which the enemy character attacks the earth is displayed, and a message indicating that the earth army has been defeated is also displayed. Then, as shown in FIG. 20D, an image of “GAME OVER” indicating the end of the story when the final round is not reached is displayed.

In this way, by changing the ending of the story according to the game state and selecting and displaying the big hit end demo screens corresponding to the different endings, the player wins V in each round, It is possible to easily know whether the process has ended after reaching the final round, or whether there is no V prize in a certain round and the process has ended without reaching the final round.

The procedure for sequentially displaying the normal demo screen, the demo screen before fluctuation start, the symbol fluctuation screen, the big hit demo screen, and the big hit end demo screen after the power of the pachinko gaming machine is turned on has been described above. The game played in response to the winning of the first bet on the variable winning ball device 8 ends when the specific game state ends and the jackpot end demonstration screen is displayed. Further, when the result of the variable display of the special symbol is not a big hit, the time when the result of the variable display of the special symbol is derived, that is, FIG. 17 (b) or FIG. 17 (f).
When the screen of is displayed, the game in response to one start winning is finished.

From the time when the big hit end demo screen is displayed or the time when a display result other than the big hit is derived on the symbol variation screen, the following two types of display control are performed. If there is a special starting memory at the above-mentioned time point or if a hit ball is won in the variable winning ball device 8 within 1 minute,
The screen of 6 (d) is displayed, and the variable display of the special symbol is started. On the other hand, if one minute or more has elapsed from the above point,
At that point, the display of the normal demo screen shown in FIG. 16A starts. If a ball is hit in the variable winning ball device 8 again while the normal demo screen is displayed, in response thereto, the pre-variation demo screens shown in FIGS. 16B and 16C are displayed. After that, the procedure of the display example described above is repeated.

In this way, in the demo screen before the start of fluctuation, the case where the special symbol is displayed in a variable manner in response to the first winning of the hit ball on the variable winning ball device 8 after the power is turned on,
At the time when a single ball hitting the variable winning ball device 8 (hereinafter referred to as "special start prize") or a series of games in response to special start memory (hereinafter referred to as "game corresponding to special start prize") is completed When the variable display of the special symbol is performed based on the special starting memory or the fact that the special starting prize is won within 1 minute. Whether or not to display the demo screen before the start of fluctuation, the timing for starting the fluctuation of the special symbol in FIGS. 7 and 8 is set to a time point at which 0.006 seconds have elapsed from the start winning or 4.68.
This corresponds to switching between the time when 6 seconds has elapsed and the time point. If the game corresponding to one special start winning is finished by the variation display of the special symbol other than the big hit, or if the specific game state is finished, one minute from that point is displayed at the end point. The previous screen will continue to be displayed. For example, when the variable display of the special symbol ends other than the big hit, the screen in which the display result is derived is 1
Displayed for minutes. When the specific game state ends, the state in which one of the two types of big hit end demonstration screens corresponding to the game state is displayed is continued for 1 minute.

Until the variation of the special symbol of the next time is started based on the special starting memory stored at the time when the game according to the special starting winning is finished or the special starting winning within 1 minute, The screen at the end of the game corresponding to the special start prize is displayed. On the other hand, if one minute has elapsed from the time when the game corresponding to the previous special start prize was finished and there was the next special start prize, 0.006 seconds have elapsed since the special start prize was detected. The display of the demo screen before the fluctuation start is started later, and the fluctuation of the special symbol is started when 4.680 seconds have passed thereafter.

FIG. 21 is a flow chart showing the procedure for selecting the type of screen to be displayed when there is a special start prize or a special start memory. In the state where the variable display of the special symbol can be performed, a special start prize or a special start memory (collectively referred to as “start prize” in FIG. 21)
It is determined whether or not there is any (S11), and if there is a start winning (Y in S11), then it is determined whether or not the normal demo screen is being displayed (S12). If the normal demo screen is being displayed (Y in S12), the display is switched to the normal demo screen and the pre-variation demo screen is displayed (S13). After displaying the demo screen before fluctuation start for 4.680 seconds, next, the symbol fluctuation screen is displayed (S14). On the other hand, if the normal demo screen is not being displayed in S12 (N in S12), the display process of the demo screen before fluctuation start in S13 is omitted and the symbol fluctuation screen in S14 is displayed.

According to the above procedure, when there is a special start prize or a special start memory, it is determined in S12 whether or not the normal demo screen is displayed, and the previous special start prize or the special start memory is responded to. It is determined whether or not 1 minute or more has elapsed since the end of the played game.

Next, with reference to FIG. 22 to FIG. 25, the processing procedure of the game control of the pachinko gaming machine of this embodiment will be described in detail, particularly the counting processing of the random counter.

FIG. 22A is a flow chart showing the processing procedure of the main program for game control. According to this main program, the CPU inside the basic circuit 26 (see FIG. 2) controls the pachinko gaming machine. The main program is executed once in response to the reset signal generated every 0.002 seconds from the clock reset pulse generation circuit 29 (see FIG. 2) during the game. When the main program is executed, the CPU first sets the stack (S31). Next, the CPU checks whether or not the contents stored in the RAM inside the basic circuit 26 are normal (S32). If the contents stored in the RAM are not normal (N in S32), the CPU initializes the RAM (S3).
3). On the other hand, if the stored contents of the RAM are normal (Y in S32), the 7-segment LED / LED / lamp circuit 31 controls the various LEDs and lamps.
And commands for the sub CPU such as the lamp / solenoid information output circuit 32 (see FIG. 2) are set (S3).
4).

Next, the CPU checks whether or not a warning signal indicating that there is an abnormality in the pachinko gaming machine has been sent (S35). This warning signal is issued from a circuit (not shown) that detects an abnormality due to an internal failure of the pachinko gaming machine, external fraud, or the like. CPU
If the warning signal has not been sent (N in S35), special symbol process processing and normal symbol process processing are performed (S36). If the warning signal is sent (Y in S35), the CPU skips the process of S36 and proceeds to the next step. Then, the CPU operates the switch input circuit 30.
(See FIG. 2), a control command is sent to perform switch input processing to check the input states from various switches such as the winning ball detector 23 and the specific ball detector 24 (S37).

The CPU, following S33 or S37,
Random creation processing for counting up the random numbers 1 to 6 is performed (S38). Note that S38 is shown as one block in the figure, but in reality, it is shown in FIG.
As shown in (b), FIG. 23, FIG. 24, and FIG. 25, individual subroutine programs are executed for each type of random counter. Subsequently, the CPU causes the I / O of the basic circuit 26 to
I / O output processing for sending a control command to various functional circuits via the O port is performed (S39).

Next, the CPU sets the interrupt count flag to "0".
Or "1" is checked (S40). The interrupt count flag is every predetermined number of times (for example, every two times) when an interrupt process for executing the main program has occurred.
Is set to "1" and is set to "0" at other times. If the number of interrupts is "1" (= 1 in S40), the CPU performs a normal symbol control process for displaying a variable of the normal symbol on the normal symbol display 7 (S).
41). If the number of interrupts is "0" (= 0 in S40), the CPU skips the normal symbol control process in S41 and proceeds to the next step.

Thus, the normal symbol control process is not performed every time the program is executed, but is performed every predetermined number of times by setting the interrupt number flag. The main program is executed every 0.002 seconds, but it is not necessary to control the symbol display 7 normally at such a short interval. Therefore, in the present embodiment, the control operation for the normal symbol display 7 is performed only when the main program is executed every predetermined number of times to reduce the load on the CPU.

After this, the remaining time is until the interrupt processing for executing the next main program is performed. The CPU executes each random creation process for counting up the random numbers 2, 3, 5, 6 at a predetermined cycle within this extra time (S42). The CPU waits for S4 until a reset signal for instructing an interrupt is input.
Each random creation process of 2 is repeatedly executed. Of the count-up timings of the various random counters described with reference to FIG. 3, the timing of adding 1 every 0.002 seconds corresponds to S38. Further, the timing of counting up by 1 at a predetermined cycle within the remaining time of the interrupt process corresponds to S42. Conventionally, only random 1 and random 4 are counted up at the timing of S38, and other random numbers 2, 3, 5, 6 and so on are S.
At 42, it was counting up within the remaining time of the interrupt process. Therefore, the step S42 may not be executed when the remaining time is short or when there is no time.

As a result, the contents decided based on the values of random 2, 3, 5, 6 and the like, for example, in the case of random 2, the planned stop symbol at the normal time of the special symbol is not updated, and the next time. The variation display is performed, and the state that the variation display stops with the combination of the special symbols of the same kind as the previous time continues, the game state becomes monotonous and the player gets bored Was occurring.
Also, in order to eliminate the above-mentioned problems, random 2, 3,
5, 6 may be updated only in S38, but in the embodiment, S
Since 42 is also updated, the randomness is further improved.

Regarding the random counter for deciding whether or not to perform the probability variation like the random 7 shown in the modified example, when the big hits due to the probability variation pattern are continuous, the emissivity is extremely high. It became a pachinko machine,
On the other hand, when the big hits due to the symbols other than the stochastic fluctuation symbols continue, the pachinko gaming machine makes the player dissatisfied, and both are not so desirable from the viewpoint of the manager of the amusement hall. Therefore, in the pachinko gaming machine of this embodiment, not only the count-up processing of random 2, 3, 5, 6 but also the random 1 and the random 4 is processed in S38, and the main program is executed once. Thus, each random counter is always updated at least once.

FIG. 22B is a flow chart showing the procedure of the random 1 creating process in S38. When the random 1 creation process is started, the CPU adds 1 to the random 1 data (S51). Next, the CPU

If the value of Random 3 is not "8" or more (<8 in S72), the process of S73 is omitted and the process proceeds to the next process.

It is input to U201. The input probability data is
It is loaded into the RAM 202 via the CPU 201. There are three types of probability data, namely, slightly higher first probability data (setting 1), medium second probability data (setting 2), and slightly lower third probability data (setting 3). , One of them is the EEPROM 213

Assuming that the probability data loaded in the RAM 202 is the first probability data (setting 1), the case where the probability setting switch 142 is operated in that state will be described. The probability setting switch 142 can be switched between three positions of a normal position (normal mode), a setting position (setting mode), and a confirmation position (confirmation mode).

When the probability setting switch 142 is in the normal mode when the power is turned on, the probability data cannot be rewritten by operating the probability setting switch 142.

As in this embodiment, the probability data is EEP
Since the ROM 213 stores and holds the memory, it is possible to flexibly cope with increase and decrease of the set value of the probability as compared with the mechanical memory holding, and there is an advantage that a backup power supply is not needed as compared with the case of storing in the RAM or the like.

The probability variation information is information indicating that the probability variation state has occurred when the probability variation state occurs due to the above-described predetermined special display result from the variable display device 4. . The valid start information is information indicating the number of start winnings that are effectively used for the variable display of the variable display device 4 among the starting prize balls that have won the starting winning opening 7. As described above, since the upper limit value of the memory of the winning start prize is set to "4", even if the pachinko ball exceeds the upper limit value and wins the starting prize hole 7, the exceeded starting prize is ignored. The number of starting winnings actually used for variable display of the variable display device 4 after subtracting the ignored number of starting winnings is output to the hall management computer as effective starting winning information.

If a pachinko ball wins the variable winning ball device 8 and the starting opening switch 25 inputs a pulse signal which is the detection output thereof to the switch circuit 218, the switch circuit 218 stops counting for the pulse width. The signal is output to the counter unit 231. In the counter unit 231,
The counting operation is stopped only while the count stop signal is input. The pulse width of the pulse signal from the starting opening switch 8 is influenced by the speed at which the pachinko balls enter the variable winning ball device 8 or the like and becomes a random pulse width. Therefore, the count stop period of the counter unit 231 is also random.
