In addition to a and 22b, various lamps and LEDs (Light Emitting Diodes) are arranged in the game area 3 and its periphery. Although not shown, the pachinko gaming machine is provided with speakers for generating various sound effects.

The normal symbol display 7 will be described. The ordinary symbol display 7 is constituted by a 7-segment display. The normal symbol display 7 starts an operation of sequentially displaying a plurality of types of symbols one by one in response to a hit ball passing through the passing opening 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 ordinary 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. To move outward, and the approach path of 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 increased. In order to distinguish a symbol displayed on the ordinary symbol display 7 from a symbol displayed on the display unit 5 described later, the symbol on the ordinary symbol display 7 is called “ordinary symbol”, and The symbol 5 is called "special symbol".

In the present embodiment, the display section 4, which is a "special design", is an LCD display, but is not limited to this, and may be a mechanical display such as a belt or a drum,
LED, fluorescent display tube, EL (electroluminescence),
Other electrical display devices such as plasma may be used.
Further, the ordinary symbol display 7 which is a “ordinary symbol” is not limited to the 7-segment display, and may be another display device described above. Further, one display device may also be used to display “special symbol” and “normal symbol”.

Next, the variable winning ball device 8 will be described. When a hit ball is awarded in the variable winning ball device 8, the display unit 5 starts changing the special symbol. In other words, the variable winning ball device 8 functions as a starting port for the variable display of symbols on the display unit 5. Normally, the left and right portions of the ball receiving member 9 provided in the variable winning ball device 8 are closed, and the approach path of the hit ball is narrowed. Then, the normal symbol is displayed in a variable manner. As a result of the variable display, if the predetermined type of the normal symbol is stopped and displayed, the left and right portions of the ball receiving member 9 are opened in response to the stop. And the path of the hit ball is widened. This makes it easier for the hit ball to win the variable prize ball device 8, and increases the chances of displaying the special symbol on the display unit 5. Variable winning ball device 8
Is detected by the starting ball detector 25.

The variable winning ball device 8 as a starting port, which is one of the means for satisfying the changing condition, is not a winning port provided with a ball receiving member as in the present embodiment, but a winning port having no ball receiving member or a passing port. It may be configured in a formula. The condition for starting the change of the special symbol is not limited to the fact that a ball is won or passed through a specific winning opening or a passing opening, and every time a predetermined number (for example, 20) of the ball is fired. You may make it hold.

The start memory display 19 provided in the variable winning ball device 8 indicates that the fact that a hit ball has passed through the passage 13 is stored. If the ball passes through the passage 13, the normal symbol display is usually displayed on the ordinary symbol display 7 when a predetermined time (0.002 seconds) elapses. When the variation is already being displayed on the ordinary symbol display 7 in response to the ball being passed through the passage 13, the fact that the ball has passed through the passage 13 is It is memorized. Then, when the variable display of the ordinary symbol display 7 is stopped and the next variation display can be started, the variable display of the ordinary symbol is started based on the memory.

The start memory display 19 flashes when it is stored that the ball has passed through the passage 13. The fact that the ball has passed through the passage 13 is stored for a maximum of four times. However, the start storage display 19 is not configured to display the number of storages. The fluctuation display of the ordinary symbol has a relatively small game value given to the player according to the display result, as compared with the fluctuation display of the special symbol described later.
Therefore, it is extremely rare for the player to be concerned about the number of times the ball has passed through the passage 13 during the game. for that reason,
In this embodiment, the start storage display 19 is configured to display only the presence or absence of storage, and not to display the number of storages. Thereby, the assembly cost of the start storage display 19 is reduced.

Next, the display unit 5 will be described. The display unit 5 is configured using 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 on the display unit 5 in each of the three regions on the left, center, and right. If the combination of the three special symbols on the left, center, and right sides when the variable display is stopped becomes a predetermined specific combination, a "big hit" occurs. When a big hit occurs, the variable prize ball device 10 changes from an unfavorable state for a player who cannot easily hit a ball (hereinafter referred to as a “second state”) to an advantageous state for a player who easily wins a hit ball. (Hereinafter, this is referred to as a “first state”). A state in which a big hit occurs and the variable winning ball device 10 is in the first state is referred to as a specific game state.

The display unit 5 displays the special symbol in addition to the above-mentioned special symbol change display, and also displays the special symbol from when the power of the pachinko gaming machine is turned on to when the ball hits the variable prize ball device 8 for the first time. For example, when the fluctuation display of the next special symbol is not performed for a predetermined time after the fluctuation display is finished,
A demonstration screen for providing predetermined information or visually entertaining, a big hit screen for enhancing a gaming effect when in a specific gaming 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, the display of the special symbol is already displayed on the display unit 5 in response to the winning of the preceding hit ball in the variable winning ball device 8. When a specific game state is established based on the result of the fluctuation display, the fact that a hit ball has been won in the variable winning ball device 8 is temporarily stored. In the following description, the memory that the hit ball has passed through the above-described passage 13 is referred to as “normal start memory”, and the memory that the hit ball has won the variable prize ball device 8 is “special start memory”. That. If there is a special start memory, the start memory display 6 lights up. Up to four special start memories are stored. The start memory display 6 has four LEDs, and turns on the number of LEDs corresponding to the stored number of the four LEDs. The player has a high interest in the special starting memory not only about the presence or absence of the memory but also the number of memories. Therefore,
In the present embodiment, the start storage indicator 6 is configured to display not only the presence / absence of storage but also the number of storage.

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

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

The normal start memory and the special start memory are specially displayed during normal symbol change display in response to the passing of the previous hit ball and specially according to the winning of the previous hit ball, respectively. It is not stored in the RAM only while the symbol is being displayed in a variable manner. When a hit ball passes through the passage 13, that fact 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, at the time when the passing of the ball and the winning of the ball are stored, unless the variable display of the ordinary symbol and the variable display of the special symbol are performed, respectively, the memory is immediately read out from the RAM and stored in the memory. Based on this, the process for performing the variable display of the normal symbol and the special symbol is started. In this case, the memory read from the RAM that the hit ball has passed and the memory that the hit ball has won are erased. In this way, not the memory immediately read and erased, but the memory read after the variable display of the ordinary symbol and the variable display of the special symbol performed at the time are finished, respectively, particularly, It is called start memory and special start memory.

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

The first state of the variable winning ball device 10 is that 29.5 seconds have elapsed since the opening and closing plate 11 was opened, or
The process ends when the earlier condition of which of the ten winning balls is won in the big winning opening 51 is satisfied, the opening / closing plate 11 is closed, and the variable winning ball device 10 is in the second state.

A special area (V pocket) is provided inside the special winning opening 51. When the hit ball that has entered the special winning opening 51 wins the specific area, the winning ball is detected by the specific ball detector 24. In the following description,
A hit ball that has won a specific area is called a “special winning ball”, and a hit ball that has won a specific area is called “V winning”. When a 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 is ended. This is called "repetition continuation control". By the repetition continuation control, the variable winning prize ball device 10 becomes the first state continuously 16 times at the maximum. In the following description, the first to 16th first repetitions will be repeated.
Are referred to as first to sixteenth rounds, respectively.

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

With the structure of the game board 1 described above, a ball is hit into the game area 3 and flows down from the upper part to the lower part.
After passing through the passage 13, the normal symbol display 7 starts to display a variable symbol. At the point in time when the fluctuation display of the ordinary symbol is stopped, if a predetermined specific type of ordinary 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 The hit ball is in a state where it is easy to win. Further, if a hit ball is hit into the game area 3 and the hit ball is awarded to the variable winning ball device 8, the display of the special symbol on the display unit 5 is started to change. When the special symbol combination is displayed at the time when the special symbol change display is stopped, the open / close 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
0 is in the first state.
The prize winning rate is significantly higher than usual. Further, when the ball hitting the special winning opening 51 enters the specific area, the first state of the variable winning ball device 10 is repeatedly continued. The player uses the pachinko gaming machine of the present embodiment,

Next, with reference to FIGS. 3 to 10, a description will be given of how a special symbol is fluctuated on the display unit 5.

FIG. 3 is an explanatory diagram showing the types and contents of random counters used for controlling 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 this embodiment, four types of random counters of random 1, 2, 3, and 6 are used to control the variable display of special symbols. The values of these random counters are read at a predetermined timing during the pachinko game, and the display of the special symbols on the display unit 5 is controlled based on the read values. Further, in FIG. 3, as a configuration of a modified example, probability fluctuation (described later)
, A random 8 for selecting the type of a big hit screen (described later), and a random 9 for controlling the display of the decorative symbol.

Random 1 is a random counter for determining in advance whether the result of the change display of the special symbol on the display unit 5 is a big hit. The procedure for determining in advance whether to generate a big hit will be described later with reference to FIG. Random 1 is counted up by 1 every 0.002 seconds in the range of “0” to “229”.

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

The interrupt processing referred to here means that, during execution of a game control main program (to be described later), an interrupt is executed in response to input of a reset signal for the next execution. Is generated, the execution of the program is interrupted at that time, and the program is re-executed from the beginning. The remaining time of the interrupt processing is the time from the end of the operation according to each of the main processing instructions included in the main program to the input of the reset signal for the next execution and the occurrence of the interrupt. That is. Random 3 is used to select and determine the procedure of the variation display of the central special symbol to be stopped last from a plurality of types when it is determined in advance that a reach is generated during the variation display of the special symbol. Is a random counter. In the present embodiment, the change of the special symbol starts simultaneously in the left, center and right regions of the display unit 5. Then, at the point in time when the predetermined time has elapsed, the variable display of each area is sequentially stopped in the order of left, right, and center. "Reach" means that when the variable display on the left stops and then the variable display on the right stops, the type of special symbol stopped on the left and right is the same, and the special symbol in the center is the same This means a state where a big hit occurs if a stop is displayed with a type of symbol. The procedure of the variable display when establishing the reach is four types of reach 1 to reach 4 as described later. 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 counts up by 1 every 0.002 seconds,
It is performed one by one at a predetermined cycle within the remaining time of the interrupt processing.

The random 6 determines the content of the fluctuating operation immediately before the fluctuating display of the central special symbol is stopped when it is determined in advance that the fluctuating display is controlled in the reach 1 or reach 2 procedure. Is a random counter.
In reach 1 and reach 2, the fluctuation speed is reduced immediately before stopping the fluctuation of the central special symbol. It is a random number 6 that 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 one symbol, if the value is "2" or "3", it is for two symbols, and if the value is "4" or "5", it is three symbols. It is determined in advance that a minute deceleration display will be performed. The random 6 is incremented by one every 0.002 seconds, and one at a predetermined cycle within the remaining time of the interrupt processing.

In the random 6, when it is determined in advance that the reach is established during the special symbol variation display, the procedure of the central special symbol variation display to be stopped last is selected from a plurality of types. It is a random counter for determining. In the present embodiment, the change display of the special symbol at the center when the reach is established as described later is displayed in reach 1 to reach 4
One of the four types is selected. The 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. The random 6 is incremented by one every 0.002 seconds, and one by one at a constant period within the remaining time of the interrupt processing.

The random 7, random 8, and random 9 described below are not used in the pachinko gaming machine of the present embodiment, but will be described as a modified example.

The random number 7 is a random counter for determining whether or not the probability of a big hit as a result of the special symbol change display is changed. The term “probability variation” refers to varying the probability that the result of the special symbol variation display will be a big hit based on the satisfaction of a predetermined condition. Random 7 is used to determine whether or not to perform the probability variation control. In this embodiment, the probability variation control is performed when the result of the variation display of the special symbol is a predetermined combination of symbols (described later). A modification may be made so as to determine whether or not to perform the fluctuation control.

The random number 7 is counted up in a range from “0” to “2”. If the value of the random number 7 is “0”, the probability that the result of the next special symbol change display will be a big hit is set high. Thereby, the probability of a big hit during the game increases, and it becomes possible to give the player an interest in the game.

Random 8 is the result of the special symbol change display,
This is a random counter for selecting the type of the big hit screen displayed on the display unit 5 when a big hit occurs and the game mode is the specific game state. In this embodiment, there is only one big hit screen. For example, three kinds of big hit screens may be prepared, and any one of them may be modified so as to be selected by a random value of 8. The random 8 is counted up in the range of “0” to “2”. The random 8 is incremented by one every 0.002 seconds, and is incremented by one at a predetermined cycle within the remaining time of the interrupt processing.

A random counter 9 is a random counter for selecting a decorative symbol. Although the pachinko gaming machine of the present embodiment does not include a means for displaying a decorative pattern,
For example, a decorative symbol display may be provided on the game board 1 shown in FIG. The decorative symbols are not directly related to the control of the game, and the game arcade exchanges prize balls awarded during the specific gaming state, for example, according to the type of the displayed decorative symbols. This is used when deciding whether or not to require the prize ball to be used for a game as it is.

The decorative symbol display is, for example, six LEs.
D. These six LEDs are numbered “1” to “6”, respectively, and the numbers are used as decorative symbols. During the special symbol variation display, the decoration symbol variation display is performed at a predetermined timing. The variation display of the decorative design is performed by sequentially lighting and displaying one of the six LEDs. The variation of the lighting is stopped when a predetermined time has elapsed, and the number of the LED that is lit at that time is set as a stop decoration symbol. This stop decoration symbol is determined in advance by the value of the random number 9. The random number 9 is counted up in a range from “0” to “5”. The counter values “0” to “5” correspond to the decorative symbols “1” to “6”, respectively. The random 9 is incremented by one every 0.002 seconds, and one by one at a predetermined cycle within the remaining time of the interrupt processing.

In the pachinko gaming machine of this embodiment, the counting up of the random 2, the random 3 and the 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, this type of random counter is incremented only within the extra time of the interrupt processing. Therefore, when there is no remaining time or short time in the interrupt processing, the random counter is not counted up. For example, the result of the fluctuation display of the special symbol is the same as the previous one and the current one, The problem that reach was not established occurred. Therefore, in this embodiment, random 1
Not only that, but also all of the random counters whose values are desirably updated within a predetermined time period have at least 0.
It is configured so that it is always counted up by one every 002 seconds. This 0.002 second is the length of the period in which the game control program including the subroutine program for counting up each random counter is periodically reset. Similarly, the random 8 and the random 9 used in the modified example are always counted up at least every 0.002 seconds. The random 1, 2, 3, and 6 count-up processing will be described later with reference to a flowchart.

FIG. 4 is a flowchart showing a procedure for determining in advance whether or not to generate a big hit based on the value of the random counter. Referring to the figure, it is determined in advance whether the result of the change display of the special symbol on the display unit 5 is a big hit or a non-big hit, and further, the type of the stop symbol of the left, center and right special symbols is determined. The procedure for the determination will be described.

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

When it is determined that a big hit is to be made, the type and arrangement of special symbols for generating a big hit are determined by subsequently determining the value of random 2. When a big hit is generated, the count value for determining the special symbol on the left side of the 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 is not a big hit, the value of random 2 is subsequently determined, and the count value for each of the special symbols on the left, right, and center is read, and The type of the stop symbol of the special symbol of the right symbol and the center is determined. In addition, when it is other than the big hit, if the combination arrangement of the special symbol determined based on the three kinds of count values of random 2 becomes the combination arrangement of the symbol which becomes the big hit by chance, the central special symbol Is added to the count value for determining, and the adjustment is made so that the fluctuation display of the special symbol is forcibly stopped in the combination arrangement of the missing symbols.

FIG. 5 shows the values of random 2 and the left, center,
It is explanatory drawing which shows the correspondence relationship between the type of stop symbol of the right special symbol. The special symbols include ten types of numeric symbols “0” to “9” and five types of character symbols “squid”, “crab”, “robot”, “Martian”, and “octopus”. The three values “0” to “9” of Random 2 for determining the type of the symbol on the left, center, and right are “0” to “0” of the numeric symbol.
"9" respectively. In addition, three values “10” to “14” of random 2 are “squid” of the character design,
Corresponds to "crab", "robot", "Martian", "octopus".

These 15 kinds of special symbols are variably displayed on the display unit 5. As a result of the variably displayed, if all the left, center and right stop symbols are of the same type, a big hit occurs. In addition, when the occurrence of the big hit is a combination of three of the symbols “3”, “5”, and “7”, the specific game state according to the occurrence of the big hit From the time when the specific game state ends, the control of the probability fluctuation of the ordinary symbol is performed. These three numerical symbols of "3", "5", and "7" are particularly called "probability changing symbols".

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

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

In the variation state G, the variation for one symbol is 0.1
The symbol fluctuates at a constant speed performed in 00 seconds. In the fluctuation state H, the fluctuation is started from the symbol two symbols before in the symbol arrangement shown in FIG. 5 of the special symbol to be a big hit, and the symbol is changed at a slow speed until the special symbol to be passed is passed. You. 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 a change for one symbol is performed in 0.100 seconds.

FIG. 7 is a timing chart showing a control procedure of a special symbol change display when a big hit does not occur and a reach is not established (hereinafter, referred to as "normal time"). When a hit ball wins in the variable winning ball device 8 (starting port in the figure), the winning ball is used as the starting ball detector 25 (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 detects the random 1 stored in the RAM at the falling edge of the detection pulse 0.002 seconds after the start winning of the ball in the variable winning ball apparatus 8 is detected. The value is read, and it is determined in advance based on the read value whether or not the result of the change display of the special symbol is a big hit. The process of determining in advance whether or not to make a big hit is performed according to the procedure shown in FIG. Along with the reading of the value of random 1 and the determination processing, the CPU
Is read. In the control procedure shown in the figure, it is determined in advance that a big hit will not occur by the determination of the value of random 1, and further, the reach cannot be established by the three kinds of values of random 2 (see FIG. 3). Determined in advance.

In a normal state, the specific procedure of the variable display of the special symbols on the left, the center and the right is as follows.
The basic circuit 26 determines the LC based on the result determined by the CPU.
A control command is sent to the D control circuit 33 (see FIG. 2),
The control circuit 33 sends a display control signal to the LCD control board 34 (see FIG. 2) based on the control command. As a result, the fluctuation of the special symbols on the left, center, and right sides starts at the same time when 0.006 or 4.686 seconds have elapsed after the winning of the ball in the variable winning ball apparatus 8 is detected on the display unit 5. Is done.

The interval between the detection of a hit ball and the start of the change of the symbol is set to 0.006 seconds or 4.6.
The time of 68 seconds is determined when the last special symbol change display ends with a big hit when the last special display change display ends other than a big hit, or when the last special symbol change display ends with a big hit. The determination is made based on whether or not the point in time at which the specific game state in response to the occurrence of the big hit ends is within one minute before the point in time when the hitting of the hit ball is detected. If any one of the above points is within one minute, the fluctuation of the symbol is started when 0.006 seconds elapse, and if not one minute, the fluctuation of the symbol is started after 4.668 seconds elapse. You.

The two reasons from when the start winning is detected to when the special symbol change display is started are set for the following reasons. When performing a special symbol change display based on the first winning prize after the power of the pachinko gaming machine is turned on, the player hardly recognizes the contents of the special symbol change display. Even if the special symbols are displayed in a fluctuating manner as it is, a specially devised special symbol does not sufficiently exert the game effect by the fluctuating display, and rather causes the player to feel dissatisfied. Therefore, in the pachinko gaming machine of the present embodiment, when the special symbol fluctuating display is performed based on the first starting winning after the pachinko gaming machine is turned on, the fluctuating display of the symbol starts more than in other cases. Is delayed. An image representing information on the variable display of the special symbol is displayed at the delayed time. The screen displayed at this time is referred to as a “pre-change start demonstration screen (simply, a“ pre-change start demonstration screen ”) in the following description.

At the time when the special symbol change display for a certain time is completed or when the specific game state is completed,
Even when there is no special start memory, the start timing of the change display of the special symbol is similarly delayed. In this case, the purpose is not to make the player recognize the content of the variable display, but to make it easier to generate a state in which the special symbol is continuously displayed in a variable manner, thereby giving the player an interest.
That is, by delaying the start timing of the variable display, the time required for the variable display is lengthened, and the start winning of the special symbol is easily stored by that much. In addition, since the actual display time of the symbols does not change, there is no need to separately improve the display control program or to use multiple complicated program modules as the time changes. It is possible to minimize an increase in the assembly cost of the gaming machine.

On the other hand, when a ball is won in the variable winning ball device 8 within a predetermined time, or when the variable display is completed or when the specific game state is completed, the special start memory is stored. No special processing for causing the player to recognize the contents of the variable display is necessary, and since the state in which the variable display is continuously performed has already occurred, there is no need to delay the start timing of the variable display. In this case, the variable display is performed based on the fact that there is a special start memory at the time when the variable winning prize ball device 8 receives the starting prize, when the previous variable display ends, or when the specific game state ends. When 0.006 seconds have elapsed from the start of the process, the variable display of the special symbols on the left, right and center is started. As described above, in the present embodiment, the timing of the change 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, display control of the fluctuation state A is performed within 5.000 seconds after the start of the fluctuation. Note that the fluctuation time in parentheses is the time when shortening fluctuation (described later) is performed. At the point of time when 5.000 seconds have elapsed, the symbol three symbols before in the symbol array of the stop symbol (hereinafter, “scheduled stop symbol”) determined in advance by the value of random 2 is set to the stop position, and thereafter, fluctuates. Display control in state B is performed. The display control of the fluctuation state B is performed for 1.000 seconds, during which fluctuations for three symbols are performed, and finally the scheduled stop symbol is stopped and displayed.

For the special symbol on the right side, the display control of the fluctuation state A is performed 6.000 seconds after the start of the fluctuation, and the display control of the fluctuation state B is then performed for 1.000 seconds. Done. In the fluctuation state B, as in the case of the fluctuation display on the left side, the symbol three symbols before the planned stop symbol is set at the stop position, and thereafter, the symbol changes for three symbols in 1.000 seconds, and finally the scheduled stop The symbol is stopped and displayed.

For the center special symbol, the display control of the fluctuation state A is performed 7.000 seconds after the start of the fluctuation, and subsequently the display control of the fluctuation state B is performed for 1.000 seconds. Done. In the fluctuation state B, similarly to the fluctuation display on the left side and the right side, the symbol three symbols before the scheduled stop symbol is set at the stop position, and thereafter, the three symbols are changed, and finally, the scheduled stop symbol. Is stopped.

FIGS. 8 and 9 are timing charts showing a control procedure of a variable display when a reach including a time when a big hit is finally generated (hereinafter referred to as "big hit") is established (hereinafter referred to as "reaching time"). is there. Note that, during the reach, when a reach that does not eventually generate a big hit is established, it is referred to as “missing reach”.

Referring to FIG. 8, at the time of the 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, the CPU of the basic circuit 26 executes
The values of random 1 and random 2 are extracted and stored in the RAM.

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

At the time of the reach, 0.002 seconds after the start winning is detected, the following processing is further performed. CPU
Are the case where it is determined in advance to generate a big hit by the determination of the value of random 1 and the case where 3
When the type value indicates that the reach is established, random 3 and random 6 values are extracted. Further, random 7, random 8, and random 9 used in the modification described with reference to FIG. 3 are extracted at this timing.

Thereafter, the display of the change of the special symbols on the left side, right side and center is started simultaneously. The timing at which the fluctuation display is started is either 0.006 seconds or 4.686 seconds after the start winning detection pulse rises, as in the normal case. The control procedure of the left variation display and the right variation display during reach is the same as the normal procedure.

With reference to FIG. 9, a description will be given of the display of the fluctuation at the center during the reach. There are four types of procedures for displaying the change at the center at the time of reach, from reach 1 to reach 4. Any one of these four types of reach is selected by a random value of three. If the value of random 3 is “0”, reach 1 is selected. The value of random 3 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 random 3 is “5” or “7”, reach 4 is selected. 6. In any of Reach 1 to Reach 4, the procedure starts after the variable display is started.
For 000 seconds, the display control of the fluctuation state A is performed, and the display is controlled to 7.0.
At the time point when 00 seconds have elapsed (at the time point “C” in the figure), the same type of symbol as the special symbol that is stopped and displayed on the left and right sides to establish 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 then the variable display on the right side has stopped. At the time of the shortening fluctuation, the period of the fluctuation state A is reduced to 3.600 seconds.

The respective control procedures of reach 1 to reach 4 after the time point C will be described individually. In the reach 1, the display control of the fluctuation state C is performed for 4.800 to 13.800 seconds thereafter. In the variation state C, the variation for 16 to 46 symbols is performed at a constant speed at which the variation for one symbol is performed in 0.300 seconds. Next, the display control of the fluctuation state D is switched from the point in time when the symbol one to three symbols earlier in the symbol array of the scheduled stop symbol is set to the stop position, and the fluctuation speed is reduced. The number of symbols from 1 to 3 symbols before which to decelerate is determined by the value of random 6. Depending on the determined number of symbols, the variation for 1 to 3 symbols is 0.400 to
It is performed for 1.200 seconds, and finally the scheduled stop symbol is stopped and displayed.

In the reach 2, the display control of the fluctuation state E is performed for 4.500 seconds from the time point C. Fluctuation state E
In this case, the fluctuation for 15 symbols is performed at a constant speed in which the fluctuation for one symbol is performed in 0.300 seconds. Thereafter, display control of the fluctuation state F is performed. In the fluctuation state F, as in the fluctuation state E, the fluctuation for one symbol is performed in 0.300 seconds at a constant speed, and the speed is changed from 4.800 to 9.300 seconds in 16 to 3 seconds.
The fluctuation for one symbol is performed.

After that, as in the case of the reach 1, the display control of the fluctuation state D is switched from the time when the symbol before any one of the symbols 1 to 3 of the scheduled stop symbols is set to the stop position. Then, the deceleration control is started. The number of symbols before the start of the deceleration control is determined by the value of the random number 6 as in the case of the reach 1. If the value of random 6 is "0" or "1", the value is "4" or "5" from one symbol before, if the value is "2" or "3", it is two symbols before. For example, the deceleration control is started three symbols before. In the fluctuation state D, the fluctuation speed is gradually reduced from 0.400 to 1.200 seconds, and the fluctuation is performed by the symbol determined by the value of the random number 6 among the 1 to 3 symbols, and finally scheduled. The fluctuation is stopped while the stop symbol is displayed.

In reach 3, the fluctuation state E
Is performed. 0.300 for one symbol
The variation of 15 symbols at a constant speed performed in 4.5 seconds is 4.5
This is performed for 00 seconds. Thereafter, display control in which the fluctuation and the pause are repeated is performed. First, the display control of the fluctuation state G is performed in 1.300 seconds. In the fluctuation state G, the fluctuation for one symbol is performed for 13 symbols at a constant speed in 0.100 seconds. Next, the fluctuation of the design is 0.
Paused for 400 seconds. Next, the fluctuation state G again
Is performed in 1.600 seconds, and a change for 16 symbols is performed. Thereafter, the fluctuation is temporarily stopped again for 0.400 seconds. Thereafter, the display control of the fluctuation state G is performed again for 1.600 to 1.700 seconds,
After the fluctuation of ~ 17 symbols, the fluctuation is stopped in a state where the scheduled stop symbol is finally stopped.

In the reach 4, the display control of the fluctuation state E is performed from the time point C, and the fluctuation for 15 symbols is performed in 4.500 seconds. After that, display control of the fluctuation state H is performed, and after fluctuations for 44 to 45 symbols have been performed in 6.900 to 7.500 seconds, the fluctuations are finally stopped in a state where the planned stop symbol is displayed. Is done.

As described above, in the pachinko gaming machine of this embodiment, at the time of the reach, any one of the plurality of control procedures of the reach 1 to the reach 5 is randomly selected and executed. Therefore, the player can play a more entertaining game with more variability than when the same control procedure is repeated every time the reach is established as in the related art.

In the reach 1 and the reach 2, the timing to start the deceleration immediately before the fluctuation display stops is selected at any time by the value of the random counter.
In conventional pachinko gaming machines, the timing at which deceleration starts is uniform. Therefore, when the player gets used to the pachinko gaming machine, it becomes possible to predict the stop symbol by looking at the type of symbol displayed when deceleration is started, thereby reducing the fun of the game. Was causing it. On the other hand, if the timing of starting the deceleration is variously changed as in the present embodiment, the player cannot predict the stop symbol before the stop of the fluctuation, and thus the expectation of the occurrence of the big hit until the fluctuation completely stops. Can be kept in the player.

Further, in reach 2, reach 3 and reach 4, when performing the display control of the fluctuation state E, the background of the display screen is switched from one type to another type as described later, Gives visual stimulus to
The game effect is enhanced.

FIG. 10A is a timing chart showing the temporal relationship between the end of the special symbol change display and the opening / closing of the special winning opening 51. The special symbol change display is started, the left symbol stops, then the right symbol stops, and finally the center symbol stops, and when the variable display ends, the combination of stopped symbols is changed. Is determined. If the combination of stop symbols is a big hit with three special symbols of the same type, the special winning opening 51 is opened when 5.000 seconds have passed since the end of the variable display. Open state of the special winning opening 51, 29.500 seconds have passed,
Alternatively, the process ends when the earlier one of the ten winning balls in the special winning opening 51 is satisfied. Also, if there is a V prize when the special winning opening 51 is in the open state, 2. after the current open state ends.
When 000 seconds have elapsed, the special winning opening 51 is again opened.

FIG. 10 (B) is a timing chart showing a temporal relationship between opening / closing of the special winning opening 51 and the start of the next special symbol change display. If a special start memory (described above) is stored when the special winning state 51 which has been opened and the special winning state 51 which has been opened is closed when a special game state of one time has ended is 12.500 seconds or 10.500. At the time when the second has elapsed, processing for performing the next variation display based on the start memory is started. 12.500 seconds and 1
At which point of time, 0.500 seconds, the processing is started, the special winning state 51 during the specific game state of that time is determined.
Is determined based on whether or not a hit ball has won. At least one hit ball is in the special winning state 51 during that particular game state.
Is started when 12.500 seconds have elapsed. In addition, if no ball is hit in the special winning opening 51 during the specific game state of that time, 1
The processing is started when 0.500 seconds have elapsed. When the process is started, random 1 and random 2 values are extracted and stored in the RAM.

Then, at the time when 0.002 seconds have elapsed, that is, at the time when 12.502 seconds or 10.502 seconds have elapsed since the closing of the special winning opening 51, the reading of the random value 1 and the judgment processing are performed. Further, a random 2 value is read. The extraction, storage, readout, determination, and the like of these random 1 and random 2 values are performed in response to the rising and falling of the detection pulse of the hit ball hitting the variable winning ball device 8 shown in FIGS. 7 and 8. Corresponding. Then, when 0.004 seconds have elapsed, that is, when 0.006 seconds have elapsed since the start of the next processing, the fluctuation of the next special symbol (only the left side is shown in the figure) is started. .

FIG. 10 (C) is a timing chart showing the temporal relationship between the end of the change display of the special symbol in a certain round and the start of the change display of the special symbol in the next round. When the variable display is started a certain time, the left symbol stops, then the right symbol stops, and finally, the central symbol stops, and when the variable display ends, the combination of stopped symbols Is determined. At that time, if there is a special start memory (described above), at the time when 0.500 seconds or 3.120 seconds have elapsed, processing for performing the next variation display based on the start memory is performed. Be started. Whether the processing is started when the time of 0.500 seconds or 3.120 seconds has elapsed depends on the type of the procedure of the variable display at that time.
When the fluctuation display is performed in the normal procedure or the procedure of Reach 1, the processing is started when 0.500 seconds have elapsed. When the fluctuation display is performed in any one of the reach 2, 3, and 4 steps, the processing is started when 3.120 seconds have elapsed.
When the process is started, random 1 and random 2 values are extracted and stored in the RAM.

Thereafter, at the time when 0.002 seconds have elapsed, that is, at the time when 0.502 seconds or 3.122 seconds have elapsed from the determination processing of the combination of stopped symbols, the reading of the random value 1 and the determination processing are performed. Further, a random 2 value is read. The extraction, storage, readout, determination, and the like of these random 1 and random 2 values are described in FIGS.
Corresponds to the processing in response to the rise and fall of the detection pulse of the hit ball that has won the variable winning ball device 8 shown in FIG.
Then, when 0.004 seconds have elapsed, that is, when 0.006 seconds have elapsed since the start of the next round, the change of the symbol on the left side of the next round is started.

As described above, in the pachinko gaming machine according to the present embodiment, when the variable display of the special symbol is continuously performed based on the special start memory, the next round of the variable display is completed from the time when the previous variable display is completed. The interval until the start of the variable display is made longer or shorter depending on the type of the control procedure of the previous variable display. At normal time (other than the reach) or at the reach 1, since the content of the control procedure is not particularly different from the conventional one, the next process is started when a relatively short time of 0.500 seconds has elapsed. On the other hand, the reach 2, 3, and 4 are variously devised in order to enhance the game effect, as shown in FIG. In order to sufficiently bring out the effects of these measures, a relatively long 3.120 is required.
When the second has elapsed, the next processing is started.

Next, with reference to FIGS. 11 to 15, the variation of the ordinary 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, "0" to "9",
One of "A", "J", "P", "H", "L", "-"
Six types of symbols are displayed in order. The display time of one symbol is 0.064 seconds, and the time of one cycle for 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. The random counter for the ordinary symbol includes a random 4 for determining in advance whether or not the result of the variable display of the ordinary symbol is a hit, and a random 5 for determining a scheduled stop symbol of the result of the variable display. There is. Random 4 is counted up by one every 0.002 seconds in the range of “3” to “12”. The random number 5 is in the range of "0" to "15", and is incremented by one at a predetermined cycle within a surplus time of the interrupt processing, one by 0.002 seconds. Note that, in addition to incrementing the count of the random 4 by 1 every 0.002 seconds, a modification may be made such that the increment is incremented by 1 at a predetermined cycle within the remaining time of the interrupt processing.

Conventionally, a random counter, such as Random 5, for determining a scheduled stop symbol of a normal symbol has been counted up only within the remaining time of the interrupt processing. Therefore, when the remaining time of the interrupt processing is short or not at all, the value of the random counter is not updated, and a monotonous gaming state in which the results of the plurality of continuous fluctuation displays are all the same type of symbol is generated. Was likely to occur. Therefore, in the present embodiment, the random 2,
Like 3 and 6, the random 5 for ordinary symbols
Along with counting up within the remaining time of the interrupt processing, 0.
The count is always incremented by one every 002 seconds.

FIG. 13 is an explanatory diagram showing the correspondence between the value of the random number 5 and the type of the scheduled stop symbol of the ordinary symbol. The scheduled stop symbol of the ordinary symbol is determined by the value of the random number 5. Random 5 values “0” to “15” are replaced with ordinary symbols “0” to “9”, “A”, “J”, “P”, “H”,
“L” and “−” are associated with each other.

FIG. 14 shows in advance whether or not the result of the variable display is a hit based on the value of Random 4 and further determines the planned stop symbol of the result of the variable display based on the value of Random 5. 6 is a flowchart showing a procedure for performing the operation. If the value of the random number 4 is “3” among “3” to “12”, it is determined in advance that the result of the variable display of the ordinary symbol is a hit. If the value of random 4 is other than "3",
It is decided beforehand that it is not a hit.

When the state is in the high probability state by the probability variation control, the value of the random 4 is "3" to "12".
In the case of "3" to "11", it is determined in advance that the result of the fluctuation display of the ordinary symbol is a hit, and when the value of the random 4 is "12", it is determined that the result is other than the hit. Determined in advance. At the normal probability when the probability variation control is not performed, the probability that the result of the variation display of the normal symbol is a hit is 1/10. In addition, when the probability variation control is performed at a high probability, the probability that the result of the variation display of the ordinary symbol is a hit is 9/10 of nine times the normal probability.

If it is determined in advance that a win or a non-win is made, then the type of the normal symbol that is finally stopped and displayed when the variable display is ended using the value of random 5 To determine. If you do not hit
A value of random 5 is extracted, and a normal symbol (see FIG. 13) corresponding to the value is set as a scheduled stop symbol of the normal symbol. At this time, if the hit symbols “3”, “5”, and “7” are accidentally selected based on the extracted values, the symbols “4” and “6” corresponding to the next values respectively. ”,“ 8 ”
To force the scheduled stop symbol to be a symbol other than a hit.

In the case of a hit, the scheduled stop symbol is determined by using a value of random 5. However, in the case of a hit,
The value of the random number 5 is associated with the type of the scheduled stop symbol as follows. If the value of the random number 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. Further, if the value is “10” to “15”, “7”
Is selected.

FIG. 15 shows a variation display of a normal symbol and a passage 1.
3 (in the illustration, the “normal design gate”)
It is a timing chart which shows the temporal relationship with the opening / closing of the variable winning prize ball device 8 ("ordinary electric accessory" in the figure), and the procedure of probability variation control.

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

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

Normally, after the change of the symbol is started, 16
The kinds of symbols are sequentially changed at a constant speed of 1.024 seconds in one cycle. And after 25,000 seconds have passed,
The fluctuation is stopped when the scheduled stop symbol is displayed. 2
It takes from 0 to 0.960 seconds depending on the type of the planned stop symbol from the time when 5.000 seconds have elapsed until the fluctuation stops.

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 the temporal relationship with closure.
(B) shows the procedure at the time of normal probability, and (c) shows the procedure at the time of high probability.

Referring to FIG. 13B, when the fluctuation of the ordinary symbol stops, the type of the stopped symbol is checked. If the stop symbol is any one of "3", "5", and "7", the ball of the variable prize ball device 8 at the time when 0.002 seconds elapse from the time when the change stops. The receiving member 9 (see FIG. 1) rotates outward when viewed from the front side,
The ball enters the variable winning ball device 8 in an open state in which the approach path of the ball is widened. 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 to the variable winning ball device 8 is narrowed and the ball receiving member 9 is closed. Becomes Thereafter, the ball is passed through the passage 13 again, and the normal symbol is displayed in a fluctuating manner, and the variable winning ball device 8 is closed until a hit occurs. On the other hand, when the variable winning prize ball device 8 is in the closed state, if there is a normal start memory, the value of random 4 is extracted and stored at the time of the closed state, and 0.002 seconds elapse thereafter. At this point, the stored value of random 4 is read and determined, and the value of random 5 is extracted, and at the same time, the next variation display of ordinary symbols is started. When a value resulting from the variable display is generated, the above-described procedure is repeated.

Referring to FIG. 13 (c), when the probability is high, the variable winning ball device 8 is opened when 0.002 seconds have elapsed since the fluctuation of the symbol usually stopped. The open state is
Continue for 2.800 seconds, then close for 7.000 seconds. Thereafter, the variable prize ball device 8 is again opened, and after the open state is continued for 2.800 seconds, the variable prize ball device 8 is closed. As described above, at the time of the high probability, the variable winning ball device 8 is opened twice for 2.800 seconds with the closed state of 7.000 seconds interposed therebetween. The probability of winning the ball device 8 is greatly increased. Note that the procedure after the second open state of the variable winning ball device 8 is completed is the same as that at the time of the normal probability. FIG. 15D is a timing chart illustrating a procedure of the probability variation control. The illustrated condition device is:
The display unit 5 (see FIG. 1). The operating state of the condition device is a state in which a large hit is generated as a result of the special symbol being fluctuated on the display unit 5 and a big hit demonstration screen in a specific game state is displayed in response thereto. The start time of the two operating states shown is the time at which the display result of the variable display of the special symbol is derived. A 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 three symbols of "3", "5", and "7" are aligned. In the case of a big hit, the specific game state due to the occurrence of the big hit (the operation state of the condition device)
The probability variation control is started from the point in time when is completed, and the probability that the result of the variation display of the normal symbol is a hit and the probability that the result of the variation display of the special symbol is a large hit are each in a high probability state. The probability variation control is terminated when the result of the special symbol variation display on the display unit 5 is subsequently generated by a combination of big hit symbols having three symbols other than "3", "5", and "7". I do.

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

FIGS. 16 (a) to 16 (g) and FIG. 17 (a)
~ (G), after the pachinko machine is powered on,
It is a screen configuration diagram showing a display example of a screen until a variable symbol is displayed on the variable winning ball device 8 in response to a special ball being changed, and the variable display is completed. The normal demonstration shown in FIG. 16A is performed from the time when the power is turned on to the time when the display of the change of the special symbol in response to the winning of the hit ball to the first variable winning ball device 8 is started. A screen (hereinafter, referred to as a “normal demo screen”) is displayed. A message for introducing the contents of the story displayed on the display unit 5 is displayed as a telop on the normal demonstration screen.

After that, when the winning of the hit ball to the variable winning ball apparatus 8 is detected, the demonstration screen before the start of the change of the special symbol shown in FIGS. Screen ") is displayed. In this embodiment, as shown in the figure, a story is displayed that 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. 16B showing a scene in which a fighter jumps off from the base of the Earth Army is displayed, and then the screen of FIG. 16C showing a scene in which a fighter flies in the sky is displayed.

FIGS. 16D to 16G displayed thereafter.
FIGS. 17A to 17G are screens for displaying a special symbol in a variable manner (hereinafter, referred to as “symbol changing screen”). As shown in FIG. 16D, on the symbol change screen,
First, an initially set symbol is displayed at a position where the change of the special symbol stops, with the image of the scene in which the fighter plane flies as a background. UFO showing the symbol following the initial symbol
An image showing the scene of the corps flying from here to the other is displayed.

Next, as shown in FIG. 16B, the change of the special symbol is started. The variation of the special symbol of this embodiment is
By displaying a scene in which the UFO with the special symbol flies from the other side to this side is displayed on the left side, the center, and the right side of the screen, the variation of the special symbol is displayed. The fluctuation of the symbol is started 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, right, and center, a missile will be fired from an Earth Army fighter to destroy the corresponding UFO. When the UFO is destroyed, the special symbol attached to the UFO is displayed at the symbol stop display position. FIG. 16F shows a state in which the UFO on the left is destroyed and the special symbol “7” is stopped and displayed.

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

FIGS. 17A to 17C show display examples of screens corresponding to the reach 1 display control. 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,
An example of a screen display until the reach is established is as shown in FIGS. FIG.
(D) shows the fluctuation state E of reach 2, 3 and 4 shown in FIG.
Is a screen displayed at the time when the display control is started.
When the reach is established, the background image of the screen is changed from the image 101 representing the earth space to the image 1 representing the outer space.
Move to 03 by scrolling. And FIG.
As shown in FIG. 17E, a state where only the center UFO fluctuates is displayed with the image 103 of the outer space in the background, and as shown in FIG. The UFO is destroyed and the stop symbol for the special symbol in the center is determined. At this point, the left, right, and center 3
When the combination of the two stop symbols is determined and a big hit occurs as shown in FIG. 17 (g), the image of “FEVER” is further added and displayed.

FIG. 18 is a schematic diagram for explaining a configuration for switching the background image from the image 101 in the terrestrial space to the image 103 in the cosmic space described with reference to FIG. In the pachinko gaming machine of the present embodiment, an image display control circuit is included inside an LCD control board 34 (see FIG. 2) controlled by the display unit 5. The basic configuration of the image display control circuit is not particularly different from the conventional one, and is not shown. The image display control circuit includes a VRAM (Video Rand) for temporarily storing image data to be displayed on the display screen.
om Access Memory). The image data stored in the VRAM is read out and displayed on the screen. FIG.
Reference numeral 8 denotes an area for storing data of an image displayed as a background during the variable display of the special symbol. The area demarcated by the chain line corresponds to a storage area for image data displayed on one screen.

As shown in the figure, in this embodiment, image data of a screen for three areas for storing a background image, that is, data having a capacity three times as large as image data that can be simultaneously displayed on the display unit 5 is stored. The size is such that it can be stored. 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 in the figure is read out. When the reach is established, the readout area of the image data is gradually moved to the upper part in the figure to scroll the background image. Finally, the image data at the top of the figure is read out and displayed on the screen as a background image. As described above, the background image is stored in a storage area having a larger capacity than the storage area of the image data for one screen, and the readout area is gradually moved as necessary, as shown in FIG. In this way, the background portion of the screen can be smoothly changed to display a realistic image.

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

Thereafter, as shown in FIG. 19B, the image is switched to the central light image, and the image of the character "1 ROUND" indicating the first round is displayed. Character is displayed. Subsequently, FIG.
As shown in (c), the image of the character representing the round is deleted, and a scene in which the enemy character attacks the fighter is displayed. If there is a V prize while this screen is displayed, a scene in which a missile is fired from a fighter and a character on the enemy side is destroyed is displayed as shown in FIG. Thereby, the player can know that there is a V prize. Further, the numerical images and the graph images for displaying the number of the big winning prize balls in FIGS. 19C and 19D show examples in which the number of the big winning prize balls won at that time is displayed. . By displaying these images, the player can easily know the number of large winning balls.

FIG. 20 is a screen configuration diagram showing a display example of a demonstration screen (hereinafter, referred to as a "big hit end demo screen") displayed from immediately before the end of the specific game state to the end of the specific game state. V in each of the first to fifteenth rounds
There is a prize, and the game proceeds to the next round sequentially by the repetition continuation control. When the final 16th round is completed, FIG.
The screen shown in (a) is displayed. As a story,
When the final round is reached, the Earth Army wins,
A message to that effect is displayed on the screen. continue,
As shown in FIG. 20 (b), an image of "THE END" indicating the end of the story when the game reaches the final round is displayed.

On the other hand, in any one of the first to fifteenth rounds, 29.5 seconds elapse without any V prize, or the number of prize balls to the special prize port 51 reaches ten,
When the round ends, the specific game state ends at that time. 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 displayed. Thereafter, as shown in FIG. 20 (d), an image of "GAME OVER" indicating the end of the story when the game has not reached the final round is displayed.

As described above, by changing the end of the story according to the game state and selecting and displaying the jackpot end demo screen corresponding to each of the different ends, the player has a V prize in each round, It is possible to easily know whether the game has ended after reaching the final round, or whether the game has ended without reaching the final round because there is no V winning in a certain round.

The procedure for displaying the normal demo screen, the demo screen before starting the fluctuation, the symbol fluctuation screen, the big hit demo screen, and the big hit end demo screen in sequence after the power of the pachinko gaming machine is turned on has been described. The game played in response to the winning of the first hit ball in the variable winning ball device 8 ends when the specific game state ends and the big hit end demonstration screen is displayed. In addition, when the result of the special symbol change display is not a big hit, the time when the result of the special symbol change display is derived, that is, FIG. 17B or FIG.
When the screen of is displayed, the game responding to one start winning is ended.

The following two types of display control are performed after the time when the big hit end demonstration screen is displayed or when the display result other than the big hit is derived on the symbol variation screen. If there is a special start memory at the above-mentioned time point, or if a hit ball is won to the variable winning ball apparatus 8 within one minute, FIG.
The screen of FIG. 6 (d) is displayed, and the variable display of the special symbol is started. On the other hand, if one minute or more has passed since the above point,
From that point, the display of the normal demonstration screen shown in FIG. If a ball is hit again on the variable winning ball device 8 while the normal demo screen is displayed, the demo screen before the start of fluctuation shown in FIGS. 16B and 16C is displayed in response thereto. Thereafter, the procedure of the above-described display example is repeated.

[0138] As described above, the demo screen before the start of the fluctuation is displayed in the case where the special symbol is displayed in response to the winning of the hit ball to the first variable winning ball device 8 after the power is turned on,
A point at which one ball hitting the variable prize ball device 8 (hereinafter referred to as "special start winning") or a series of games in response to the special starting memory (hereinafter referred to as "game corresponding to special starting winning") is completed. Is displayed based on the special start memory or when the special symbol is changed within one minute. Whether or not to display the pre-change start demonstration screen may be determined by starting the change of the special symbol in FIGS. 7 and 8 at a point of time when 0.006 seconds have elapsed since the start winning, or 4.68.
This corresponds to switching between the time points when 6 seconds have elapsed. If the game corresponding to one special start prize is ended due to the change of the special symbol being displayed other than the big hit or the end of the specific game state, it is displayed at the end point for one minute from that point. The previous screen is displayed continuously. For example, when the change display of the special symbol ends at a place other than the big hit, the screen in a state where the display result is derived is 1
Displayed for minutes. When the specific game state ends, a state in which one of the two types of big hit end demonstration screens corresponding to the game state is displayed is continued for one minute.

Until the next special symbol change is started based on the special start memory stored at the time when the game corresponding to the special start winning is completed or the special start winning within one minute, A screen at the end of the game according to the special start winning is displayed. On the other hand, if one minute has elapsed since the game corresponding to the previous special start winning and the next special start winning has occurred, 0.006 seconds have elapsed since the special start winning was detected. The display of the pre-change start demonstration screen is started later, and the change of the special symbol starts after 4.680 seconds have elapsed.

FIG. 21 is a flowchart showing a procedure for selecting a type of screen to be displayed when a special start winning or a special start memory is found. In a state in which the special symbol can be displayed in a variable manner, a special start winning or a special start memory (collectively referred to as “start winning” in FIG. 21)
It is determined whether or not there is (S11). If there is a start winning (Y in S11), it is then determined whether or not the normal demonstration screen is being displayed (S12). If the normal demonstration screen is being displayed (Y in S12), the display is switched to the normal demonstration screen and the pre-change start demonstration screen is displayed (S13). After the demo screen before the start of change is displayed for 4.680 seconds, a symbol change screen is displayed next (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 the start of change in S13 is omitted and the symbol change screen is displayed in S14.

According to the above procedure, if there is a special start winning or special starting memory, it is determined in S12 whether or not the normal demonstration screen is displayed, and a response is made to the previous special starting winning or special starting memory. It is determined whether one minute or more has passed since the end of the game.

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

FIG. 22 (a) is a flowchart showing a processing procedure of a main program for game control. According to the 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 a 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 a stack (S31). Next, the CPU checks whether the contents stored in the RAM inside the basic circuit 26 are normal (S32). If the content of the RAM is not normal (N in S32), the CPU initializes the RAM (S3).
3). On the other hand, if the contents stored in the RAM are normal (Y in S32), the CPU executes a 7-segment LED / LED / lamp circuit 31 to control various LEDs and lamps.
Command for the sub CPU such as the CPU and the lamp / solenoid information output circuit 32 (see FIG. 2) (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) for detecting an abnormality caused by a failure inside the pachinko gaming machine or an external misconduct. CPU
If the warning signal has not been sent (N in S35), the special symbol process and the normal symbol process are performed (S36). If a warning signal has been sent (Y in S35), the CPU skips each process in S36 and proceeds to the next step. Subsequently, the CPU operates the switch input circuit 30.
(See FIG. 2), a switch input process is performed, and input states from various switches such as the winning ball detector 23 and the specific ball detector 24 are checked (S37).

After S33 or S37, the CPU proceeds to
A random creation process for counting up random numbers 1 to 6 is performed (S38). Although S38 is shown by one block in the figure, it is actually shown in FIG.
(B) As shown in FIGS. 23, 24 and 25, an individual subroutine program is executed for each type of random counter. Subsequently, the CPU sets the I / O
An I / O output process 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 a predetermined number of times (for example, every two times) that an interrupt process for executing the main program has occurred.
Is set to "1", and "0" is set at other times. If the number of interruptions is "1" (= 1 in S40), the CPU performs a normal symbol control process for performing a variable display of the normal symbol on the ordinary symbol display 7 (S40).
41). If the number of interrupts is "0" (= 0 in S40), the CPU skips the ordinary symbol control process in S41 and proceeds to the next step.

As a result, the normal symbol control process is not performed at all times when the program is executed, but at every predetermined number of times by setting the interrupt number flag. Although the main program is executed every 0.002 seconds, it is not usually necessary to control the symbol display 7 at such short intervals. Thus, in the present embodiment, the control operation for the symbol display 7 is normally performed only at every predetermined execution of the main program, so that the load on the CPU is reduced.

[0148] Thereafter, the remaining time 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, and 6 at a predetermined cycle within the extra time (S42). The CPU executes S4 until a reset signal for commanding an interrupt is input.
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 by 0.002 seconds corresponds to S38. The timing of counting up one by one at a predetermined cycle within the remaining time of the interrupt processing corresponds to S42. Conventionally, only random 1 and random 4 are counted up at the timing of S38, and other random 2, 3, 5, 6, etc.
At 42, the count was incremented within the remaining time of the interrupt processing. For this reason, if the time is too short or not at all, the step of S42 may not be executed.

As a result, the contents determined based on the values of random 2, 3, 5, 6, etc., for example, in the case of random 2, the normal scheduled stop symbol of the special symbol is not updated and the next time. The state where the variable display is performed and the variable display stops with the combination of the same kind of special symbol as the previous time continues, the game state becomes monotonous, and the player gets tired Had occurred.
In order to solve the above-mentioned problem, random 2, 3,
5 and 6 may be updated only in S38, but in the embodiment, S
Since 42 is also updated, the randomness is further improved.

Also, as with the random counter 7 for determining whether or not to perform the probability fluctuation as in the case of the random 7 shown in the modified example, if the large hits due to the probability fluctuation symbols are continuous, the shootability is extremely high. Became a pachinko machine,
On the other hand, when the big hits by the symbols other than the probability variation symbols continue, the game becomes a pachinko gaming machine that makes the player dissatisfied, and both are not very desirable from the viewpoint of the management of the game arcade. Therefore, in the pachinko gaming machine of this embodiment, the random 2, 3, 5, and 6 count-up processing is performed not only in S42 but also in random 1 and random 4 in S38, so that the main program is executed once. Thus, each random counter is always updated at least once.

FIG. 22B is a flowchart showing the procedure of the random 1 creation process in S38. When the random 1 creation process is started, the CPU adds 1 to random 1 data (S51). Next, the CPU:
It is checked whether the value of random 1 is equal to or greater than “230” (S52). The CPU determines that the value of the random 1 is “23”.

Then, the data of random 2 + 0 is cleared, and 1 is added to the random 2 + 1 data (S63). Next, the CPU checks whether or not the value of the random 2 + 1 is “15” or more (S64).
If the value of the random 2 + 1 is equal to or more than “15” (S64 ≧ 15), the CPU clears the random 2 + 1 data and adds 1 to the random 2 + 2 data (S64).
65). Next, the CPU determines that the value of random 2 + 2 is “1”.
It is checked whether or not the number is "5" or more (S66). CP

≥15), clear random 2 + 2 data (S
67).

On the other hand, the CPU proceeds to S62, S64, S
If the value of random 2 + 0, 1 and 2 is not equal to or greater than “15” in each of steps 66 (<15 in steps S62, S64 and S66), the processing of steps S63, S65 and S67 following each step is omitted, and Processing proceeds to

FIG. 24A is a flowchart showing the procedure of the random 3 creation process shown in S38 and S42. When the random 3 creation process is started, the CPU
Adds 1 to three random data (S71). Next, the CPU checks whether the value of the random number 3 is “8” or more (S72). If the value of random 3 is equal to or more than “8” (≧ 08 in S72), the CPU clears the data of random 3 (S73). On the other hand, CPU
If the value of the random number 3 is not "8" or more (<8 in S72), the process of S73 is skipped and the process proceeds to the next process.

FIG. 24B is a flowchart showing the procedure of the random 4 creating process shown in S38. When the random 3 creation process is started, the CPU adds 1 to the random 4 data (S81). Next, the CPU:
It is checked whether the value of the random number 4 is “13” or more (S82). The CPU sets the value of random 4 to “13”.
If this is the case (≧ 13 in S82), the random 4 data is cleared (S83). On the other hand, the CPU determines that the value of the random 4 is not “13” or more (<1 in S82).
3) Omit the processing of S83 and proceed to the next processing.

FIG. 25A is a flowchart showing the procedure of the random 5 creation processing shown in S38 and S42. When the random 5 creation process is started, the CPU

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

If 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 stored in the EEP
Since the data is stored and stored in the ROM 213, it is possible to flexibly cope with the increase and decrease of the set value of the probability as compared with the mechanical storage and, for example, does not require a backup power supply as compared with storing in a RAM or the like. This is advantageous when there is a problem and the period for retaining the memory is lengthened. Note that the variable probability setting means including the probability setting switch 142 or the like may be configured by, for example, a keyboard connected to a hall management computer which is a host computer of the game hall, instead of being provided in each pachinko gaming machine, A probability setting operation may be performed by designating each pachinko gaming machine in a management room of a game arcade or the like.

The effective start information is information indicating the number of start winnings effectively used for variable display on the variable display device 4 among the start winning balls that have won the start winning opening 7. As described above, since the upper limit of the start winning prize memory is set to “4”, even if the pachinko ball exceeds the upper limit and wins in the starting prize opening 7, the starting prize beyond that is ignored. Yes, only the number of start winnings effectively used for variable display of the variable display device 4 after subtracting the ignored starting winnings is output to the hall management computer as effective start winning information.

When a pachinko ball wins the variable winning ball device 8 and the starting port switch 25 inputs a pulse signal as a detection output to the switch circuit 218, the switch circuit 218 stops counting for a period corresponding to 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 being input. Since the pulse width of the pulse signal from the starting port switch 8 is affected by the speed of pachinko balls entering the variable prize ball device 8 and the like, the pulse width becomes random, so that the count stop period of the counter unit 231 is also random.
