As a big winning port, there are an auxiliary big winning port 601 for enabling the game ball to enter for an infinitesimal time only in the case of the big jackpot non-notification mode, and a main big winning port 61 for controlling the function as the big winning port excepting the case where that auxiliary big winning port 601 acts for the ball entry. Moreover, an auxiliary variable winning device is disposed in a warp passage 640 of a center frame 35.

Description

  The present invention relates to a gaming machine.

  Conventionally, when a game ball enters (starts with) a winning winning opening on a pachinko machine, it is displayed in a plurality of display areas of the symbol display device, for example, three display areas arranged in the left-right direction, and the symbols change and stop. If the later symbols (stop symbols) are aligned in a predetermined pattern, there will be a big hit and the big prize opening will be opened. Also, to increase the player's interest by changing the probability of a big hit (hit probability) on the condition that it stops at a specific type of symbol, for example, “7, 7, 7” or “3, 3, 3”, etc. The model which made it becomes common (refer the following patent document 1).

Japanese Patent Application Laid-Open No. 07-613

  However, in the above-described technology, if the symbols after the stop (stop symbols) are aligned in a predetermined symbol, the big winning opening will be opened and closed by reaching a big win, so the reach action in the decorative symbol display device, etc. The game itself has to be monotonous even if it is devised. In addition, when a jackpot with probability variation occurs, a series of flows becomes uniform since the winning prize opening / closing is always opened and closed after the jackpot is reached and the state shifts to a probability variation state. As a result, there was a problem that the superiority over other models could not be demonstrated and the operating rate of the gaming machine could not be improved.

  Therefore, the present invention exerts advantages over other models by suppressing the game itself from becoming monotonous and the flow at the time of jackpot with probability fluctuations from becoming uniform, thereby enabling the operation of the gaming machine. The purpose is to provide a gaming machine capable of dramatically increasing the rate.

The gaming machine according to the present invention is
Special game state lottery means for deciding whether or not to shift to a special game state that is more advantageous for the player than the normal game, with the winning of the game ball at the starting port,
Fluctuating gaming state lottery means for determining whether or not the varying gaming state performed after the end of the special gaming state is accompanied by a probability variation triggered by the winning of a game ball at the starting port,
A variable winning device whose opening is opened and closed in the case of the special gaming state;
First display means for variably displaying a plurality of symbols;
In a gaming machine equipped with
The transition to the special gaming state is determined by the special gaming state lottery means, and the probability changing state is determined by the variable gaming state lottery means, so that the normal gaming state is changed to the special gaming state with probability variation. When the transition is confirmed, as a display mode of the first display means at the time of the determination, a special game state notification mode for notifying the player that the game state is a special game state with probability variation, and a special game state with probability variation And a special gaming state non-notification mode in which the player is not notified that,
As the variable winning device, a sub variable winning device capable of entering a game ball existing in the center frame for a very short time only when the special gaming state is not notified, and the sub variable winning device can enter. And a main variable winning device that controls the function as a variable winning device, except when operating in the same manner.

  According to the present invention, the game itself is monotonous, and the flow at the time of jackpot with probability variation is suppressed to be uniform, thereby demonstrating advantages over other models, thereby operating the gaming machine An excellent effect is achieved in that the rate can be dramatically improved.

The gaming machine of means 1 according to the present invention is:
Special game state lottery means for deciding whether or not to shift to a special game state that is more advantageous for the player than the normal game, with the winning of the game ball at the starting port,
Fluctuating gaming state lottery means for determining whether or not the varying gaming state performed after the end of the special gaming state is accompanied by a probability variation triggered by the winning of a game ball at the starting port,
A variable winning device whose opening is opened and closed in the case of the special gaming state;
First display means provided in the center frame for variably displaying a plurality of symbols;
In a gaming machine equipped with
The transition to the special gaming state is determined by the special gaming state lottery means, and the probability changing state is determined by the variable gaming state lottery means, so that the normal gaming state is changed to the special gaming state with probability variation. When the transition is confirmed, as a display mode of the first display means at the time of the determination, a special game state notification mode for notifying the player that the game state is a special game state with probability variation, and a special game state with probability variation And a special gaming state non-notification mode in which the player is not notified that,
As the variable winning device, a sub variable winning device capable of entering a game ball existing in the center frame for a very short time only when the special gaming state is not notified, and the sub variable winning device can enter. And a main variable winning device that controls the function as a variable winning device, except when operating in the same manner.

  When it is determined that a transition to the special game state with probability variation is established, the display mode displayed by the first display means is a special game state notification mode (first game state) for notifying the player that the game state is a special game state with probability variation. In addition to the same numbers (for example, 7, 7, and 7 on the active line of one display means), the special gaming state is not notified to the player that the special gaming state with probability variation is present. Since there is a notification mode (the same number, for example, 7, 7 and 7 are not aligned on the effective line of the first display means), it can be surprising to the player and the game itself Can be suppressed from becoming monotonous, and the flow in the special game state with probability variation can be suppressed from becoming uniform. As a result, the superiority over other models is sufficiently exhibited, so that the operating rate of the gaming machine in the game hall can be dramatically improved.

  In addition, there is an existing rule that a variable winning device (large winning a prize opening) must be opened whenever a transition is made to a special gaming state. However, if an existing variable winning device is opened, an extremely small opening time is required. Even so, since the variable winning device is a player's gaze point, the player will realize that the special gaming state with probability variation has started simultaneously with the opening of the variable winning device. In contrast to this, in addition to the main variable winning device, which is the existing variable winning device, as described above, the game ball in the center frame can be entered for a very short time only when the special gaming state is not notified. If the secondary variable winning device is provided, the secondary variable winning device has a very small number of openings, so that it does not become a gaze point for the player. Therefore, even if the secondary variable winning device is opened, it is possible to prevent the player from realizing that the special game state with probability variation is started simultaneously with the opening.

  Furthermore, if the sub-variable winning device is provided in the existing center frame, there is no need to separately provide the sub-variable winning device in the game board excluding the center frame. Therefore, it is possible to prevent a decrease in the degree of freedom in design due to the restriction of the game ball passage.

  In addition, although a sub variable winning device is provided in the center frame, the proportion of game balls that enter the center frame can usually be changed by adjusting the distance between the nails. Therefore, since the proportion of game balls that enter the center frame can be easily changed at the game hall, it is easy to adjust the ball exit at the game hall.

  Also, if a secondary variable winning device is provided in the center frame, there is no need to separately provide an accessory for installing the secondary variable winning device, so that the cost of the gaming machine can be reduced, and the center frame Since it is extremely difficult to intrude a piano wire or the like, fraudulent acts can be suppressed.

Mean 2: In the pachinko gaming machine of means 1, after the game ball enters the inside of the game board that is difficult for the player to see from the surface of the game board that can be seen by the player, the warp passage that appears on the surface of the game board again in the center frame In addition, the auxiliary variable winning device is provided with the warp passage, and in the special gaming state non-notification mode, guiding means for enabling winning of a game ball to the auxiliary variable winning device is provided in the warp passage. It is characterized by.
In this way, by providing the secondary variable winning device in the warp passage, even if a game ball wins the secondary variable winning device when the above-mentioned special special gaming state occurs, this state causes a special change. The possibility of giving the player the recognition that the player is a player is extremely small.

Means 3: The pachinko gaming machine of means 1 is characterized in that a stage in which a game ball swings is provided in the center frame, and the sub-variable winning device is provided on this stage.
In this way, by providing the secondary variable winning device on the stage where the player does not pay much attention, even if a game ball wins the secondary variable winning device when the above-mentioned special special gaming state occurs, this state There is very little risk of giving the player the perception that a particular change has occurred.

Means 4: In the pachinko gaming machine of means 1 to means 3, the guiding means is composed of a passage switching member that guides the game ball to the auxiliary variable winning device in the warp passage, and a driving means that operates the passage switching member. It is characterized by being.
With this configuration, the existing warp path can be used as it is, and can be linked to the auxiliary variable winning device, and the object of the present invention can be achieved with a simple structural improvement.

Means 5: In the gaming machines of means 1 to means 4, in the probability variation state in the special gaming state non-notification mode, the display mode of the first display unit is configured to be the same as in normal times. .
In this way, in the probability variation state in the special gaming state non-notification mode, the display mode of the first display means is the same as in the normal state (the background color or the like does not change or the character is the same). If so, the display mode of the first display means does not change even in the probability variation state after the end of the special gaming state, so that it is difficult for the player to recognize that the probability variation state exists.

Means 6: In the gaming machines of Means 1 to 5, the starting port is provided with an opening / closing member capable of taking an open position for guiding the game ball and a closed position where the game ball is difficult to enter, so that the special game state is not notified. In the probability variation state in the aspect, the opening / closing operation of the opening / closing member is configured to be the same as in a normal state.
In this way, in the probability variation state in the special gaming state non-notification mode, if the opening / closing operation of the opening / closing member is configured to be the same as in the normal state, the probability variation state after the special gaming state has occurred Is hard to be recognized by the player.

Means 7: In the gaming machine of means 6, a wavy stage disposed above the start opening;
A windmill disposed below the stage;
In order to suppress the entrance of game balls to the above starting opening normally, the entrance of game balls is promoted after the special game state of the special game state with probability change ends and the state changes to the probability change state. A windmill control mechanism for controlling the position of the windmill,
It is characterized by having.
In this way, after providing a windmill and a windmill control mechanism for controlling the windmill, the game ball that has dropped from the stage is normally restricted from entering the start port of the game ball, and after shifting to the probability fluctuation state By promoting the entry, the benefits that were originally enjoyed when the special gaming state with probability variation occurred, for example, winnings due to the operation of the opening / closing member, etc. are operated as a result of introducing the non-notification mode. By controlling the windmill in this way, it can be enjoyed in another form without being noticed by the player, and there is a disadvantage by introducing a non-notification mode It can be prevented from occurring.

Means 8: In the gaming machine of means 7, the wavy stage is provided with a recess for guiding a game ball,
The windmill control mechanism arranges the support shaft of the windmill on a virtual extension line at the center of the recess and on the lateral side of the start port, and normally the front end side of the support shaft is used as the start port. Inclination and displacement in the approaching direction suppresses the entry of the game ball into the starting port, and in the special gaming state non-notification mode, the tip of the support shaft is inclined and displaced in the direction away from the starting port to enter the gaming ball. It is comprised so that it may promote.
This makes it possible to control the entry of the game ball into the start opening with only a slight change that tilts and displaces the tip end of the support shaft of the windmill, so that the player is not aware that the ball is in a non-notification mode. Benefits can be realized according to the gaming state.

Means 9: In the gaming machine of means 7 or 8, the windmill control mechanism is provided on the lateral side of the life nail of the start opening so that the game ball guided by the windmill enters the start opening with higher probability. A guide nail is included.
Thus, by providing the guide nail on the lateral side of the life nail of the start opening, it is possible to make the control when the game ball enters the start opening by the windmill described above more reliable.

Means 10: In the gaming machine of means 5 to means 9, detecting means for detecting that the player has released his hand from the game ball launch handle;
A holding ball presence / absence determining means for determining whether or not a holding ball of the special game state lottery exists;
A sudden probability change state flag indicating that the probability change of the special game state non-notification mode is in progress;
Informing means for informing that the probability change of the special gaming state non-notification mode is in progress,
Notification control means for controlling the driving of the notification means;
With
The notification control means, during the probability variation of the special gaming state non-notification mode, the player has released his hand from the game ball launch handle according to the detection result of the detection means and the determination result of the holding ball presence / absence determination means, and The notifying means is driven when two conditions are satisfied, ie, there is no holding ball.

  In the gaming machines of means 5 to 9, since the effect is made to make it difficult for the player to recognize even during the probability fluctuation, the game ends without being recognized as it is (distant from the gaming machine) Leave the amusement park). Therefore, during the probability variation of the special game state non-notification mode, the player has released his / her hand from the game ball launching handle and there is no reserved ball according to the detection result of the detection unit and the determination result of the holding ball presence / absence determining unit. It is possible to prevent the player's disadvantages by driving the notification means when the two conditions are satisfied.

Means 11: In the gaming machines of Means 5 to 9, when the probability variation of the special game state non-notification mode is more than the specified number of times in the first display means, the player is in a probability variation state. This is notified.
As in the above configuration, if the player is informed of the probability variation state when the variation of the symbol on the first display means exceeds the specified number of times, the same effect as the means 10 is exhibited.

Means 12: In the gaming machines of means 1 to means 4, in the probability variation state in the special gaming state non-notification mode, the display mode of the first display unit is configured to be different from the normal mode.
As described above, in the probability variation state in the special gaming state non-notification mode, if the display mode of the first display means is different from the normal mode, the special gaming state has occurred when the auxiliary variable winning device is activated. Is not easily recognized by the player, but the player can be surely recognized that the player has shifted to the subsequent probability variation state.
Note that the display mode is different from the normal mode, for example, by changing the character from the normal mode or changing the background color from the normal mode.

Means 13: In the gaming machines of means 1 to means 4 and means 12, the start port is provided with an opening / closing member capable of taking an open position for guiding the game ball and a closed position where the game ball is difficult to enter. The opening / closing member in the probability variation state of the gaming state non-notification mode is characterized in that the opening / closing operation is performed so that the probability of entering the opening / closing member is higher than normal.
If the opening / closing operation of the opening / closing member in the probability variation state of the special gaming state non-notification mode is performed so that the probability of entering the opening / closing member is higher than normal, the opening / closing operation of the opening / closing member changes. Therefore, it is difficult for the player to recognize that the special gaming state has occurred when the secondary variable winning device is activated, but the player can be surely recognized that the state has shifted to the subsequent probability variation state.

Means 14: In the gaming machine of means 1 to means 13, a second display means is provided in the game board, and this second display means is not only in the special game state notification mode but also in the special game state non-notification mode. Even so, it is characterized in that it is configured to notify that it is in a special gaming state.
Generally, the second display means is not watched by the gaming machine like the first display means. This is because the second display means is usually only the lamp blinking. Therefore, even when the special gaming state is not notified, the player is less likely to be aware of the special gaming state. Further, since the manager in the game hall can confirm that the game is in the special game state from the second display means, convenience is improved.

[First embodiment]
Hereinafter, the best mode of the present invention will be described in detail with reference to the drawings. Here, pachinko machines (hereinafter simply referred to as “pachinko machines”) are given as gaming machines. However, the present invention is not limited to a winning device for pachinko machines, and generally uses gaming machines on a gaming board using a sphere. The prize-winning apparatus can be targeted. It should be noted that the embodiment can be appropriately changed in design without departing from the gist of the present invention.

(Configuration of front side of pachinko machine)
FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view of the pachinko machine 10.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. ing. Below, the structure of the outer frame 11 and the inner frame 12 is demonstrated separately.

  The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of a light metal such as resin or aluminum. This is because such a configuration can reduce the weight of the pachinko machine.

  On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the position where the handle (game ball launching handle 18 described later) is installed as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as the axis. If the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation location side (the right side of the pachinko machine 10 in FIG. 1), the game ball launching handle is opened when the inner frame 12 is opened. This is because the 18 heads and the like interfere with adjacent pachinko machines and card units (ball lending units), and the inner frame 12 cannot be fully opened. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  The inner frame 12 is roughly divided into a lower pan unit 13 attached to the lowermost portion thereof, and a vertical opening / closing axis on the left side of the inner frame 12 in the range above the lower pan unit 13 as an axis. The front frame set 14 is attached so as to be openable and closable, a resin base (not shown), and a game board 30 (described later) attached to the rear side of the resin base. Each of these configurations will be described in detail below.

  The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. On the front side of the lower tray unit 13, a lower tray 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 are provided. The lower tray 15 serving as a ball receiving tray is provided at substantially the center of the lower tray unit 13 and plays a role of stopping a game ball discharged from the discharge port 16 when the upper tray described later becomes full. is there. The ball removal lever 17 is for removing a game ball in the lower tray 15, and by moving the ball removal lever 17 to the left in FIG. 1, a predetermined location on the bottom surface of the lower tray 15 is opened. The game ball stopped in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launching handle 18 by the player, the game ball is driven toward a game board 30 described later by a game ball launching device having a launch solenoid. The sound output port 24 is an output port for outputting sound from a speaker provided in the lower plate unit 13 or on the back surface. The ashtray 22 is provided on the left side of the lower plate 15. The right side of the ashtray 22 is supported by the lower plate 15 so as to rotate about the axis in the left-right direction (horizontal direction) as an axis (for example, forwardly toward the front side).

  Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion behind the lower plate are formed of flame-retardant ABS resin. For this reason, this part is hard to burn.

  On the other hand, an upper plate 19 as a receiving tray for game balls is provided integrally with the front frame set 14 at a lower portion of the front frame set 14 (above the lower plate 15 described above). The upper plate 19 is a ball tray for temporarily storing the game balls and guiding them to a game ball launching device (not shown) while aligning them in a line. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame set, and the upper decorative frame is provided on the front decorative frame. The upper plate 19 is provided directly to the front frame set 14 and is omitted. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin. In addition, an effect button 79 for the player to perform an operation such as changing the background of the decorative symbol display device 42 is provided at the lower left of the upper plate 19.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or the like. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and lighting or blinking in the big hit gaming state, it is in a big hit gaming state It is the structure which alert | reports.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  Next, the configuration of the game board 30 will be described with reference to FIGS. 3 is a front view showing the configuration of the game board 30, FIG. 4 is a diagram schematically showing the vicinity of the main prize winning opening 61, and FIG. 5 is a perspective view showing the configuration of the game board 30. The game board 30 includes a first start port 33 and a second start port 34 (through gate) each comprising a general winning port 31, a variable winning device 32, an upper starting port 33a and a lower starting port 33b (configured by an operation chuck 33b). And a special symbol display device 38, a normal symbol display device 41, a decorative symbol display device 42, and the like. The general winning port 31, the variable winning device 32, the first starting port 33, the second starting port 34, the special symbol display device 38, the normal symbol display device 41, the decorative symbol display device 42 and the like are provided. The center frame 35 and the like are respectively disposed in the through holes formed by router processing in the game board 30 and attached from the front side of the game board 30 with wood screws or the like.

  Further, as shown in FIG. 4, a pair of opening and closing blades 60 are provided at the entrance of the lower start opening 33b, and an open position for guiding the game ball and a blockage that prevents the game ball from entering the lower start opening 33b. Can take a position. The opening / closing blade 60 is driven by a solenoid SL1 (see FIG. 12) disposed on the back side of the game board 30. In addition, a main prize winning port 61 is disposed below the lower start port 33b. The main prize winning opening 61 is normally closed by the shutter 62 and is opened when the special gaming state is reached. The shutter 62 is driven by a solenoid SL2 (see FIG. 12) disposed on the back side of the game board 30.

  A game ball enters the above-described general winning port 31, variable winning device 32, and first start port 33, and the received ball is detected by a detection switch (a winning port switch, a count switch, an operation port switch, etc.) described later. Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15). In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. A number of nails are implanted in the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (instruments) are arranged.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to perform jackpot lottery, setting of symbol display of the special symbol display device 38, and the like. Specifically, as shown in FIG. 14, a counter group related to a special symbol and a counter group related to a normal symbol are provided. First, a counter group related to special symbols will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the special symbol display device 38, and the special symbol display device 38 fluctuate. Stop pattern selection counter C3 used for selection of stop patterns (corresponding to reach lottery of reaching or completely losing in the variation of decorative symbols) and initial value setting of jackpot random number counter C1 An initial value random number counter CINI1 and variation type counters CS1 to CS3 for determining a type used for variation pattern selection are provided.

  Here, the variation pattern means each pattern (form) in a case where features having common features of variation display are divided.

  Each of the counters C1 to C3, CINI1, CS1 to CS3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 700 composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the start port 33 is provided. Each value of the jackpot random number counter C1, the jackpot symbol counter C2 and the stop pattern selection counter C3 is stored in accordance with the winning timing.

  Next, the specific contents of each counter will be described in detail.

  The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 738), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “373, 727” There are 14 random numbers that are big hits at high probability, and the values are “59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 577, 631, 683, 733”. is there. Note that the high probability means that the special symbol combination is a predetermined symbol combination that is a predetermined probability variation symbol (in this embodiment, the special symbol display lamps 38a and 38b are both lit in blue or red). This is a state in which the jackpot probability is increased and the subsequent jackpot probability is increased as a value added, that is, the so-called probability change, and the normal time (low probability) is not such a probability change state (in this embodiment, the special symbol display lamp 38a is When it lights up in blue).

  The jackpot symbol counter C2 determines a symbol at the time of a jackpot when the special symbol display device 38 stops changing the special symbol. For example, the jackpot symbol counter C2 is incremented by one within a range of 0 to 9, and the maximum value (that is, 9 ), And then it returns to 0. For example, when the value of the jackpot symbol counter C2 is “0”, “4”, “5”, “6”, the special symbol display lamp 38a stops in blue, and the combination of the stopped symbols in this case is It means non-specific symbol (normal jackpot symbol). Note that this jackpot symbol is a symbol that matches evenly in the decorative symbol.

  The value of the jackpot symbol counter C2 is “1”, “2”, “3”, “7”, which is a notification pattern probability variation (normal probability variation), and the stop symbols in this case are special symbol display lamps 38a and 38b. Both stop in red. On the other hand, the value of the jackpot symbol counter C2 is “8”, “9” is non-notification mode probability variation (sudden probability variation), and in this case, the special symbol display lamps 38a and 38b both stop in blue. . Note that in the case of the notice pattern probability variation, the decorative symbols are odd numbers that match, whereas in the case of the non-notification mode probability variation, the decoration symbols are not aligned in the same manner as the detachment.

  The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start port 33.

  The stop pattern selection counter C3 is, for example, incremented by 1 in the range of 0 to 238, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the special symbol variation display is configured to be expressed by the two display lamps 38a and 38b. Therefore, in the case of the special symbol, there is no concept of reach, and a stop pattern corresponding to reach is displayed. It is decided by the stop pattern selection counter C3. On the other hand, in the case of a decorative symbol, since three decorative symbols are stopped, there is a reach. Therefore, in the case of a decorative design, the reach lottery is determined by the stop pattern selection counter C3. That is, in the case of a decorative design, after the reach has occurred, the final stop symbol is shifted by one shift before and after the reach symbol, and the stop symbol is stopped before and after the reach symbol. It is decided to draw “reach other than front / rear off” to stop and “complete out” that does not cause reach. For example, the stop pattern selection counter C3 = 0 to 201 corresponds to complete detachment, the stop pattern selection counter C3 = 202 to 208 corresponds to anteroposterior detachment reach, and the stop pattern selection counter C3 = 209 to 238 lies other than detachment anteroposterior. Applicable.

  Here, “reach” means that after the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts variable display, the combination of symbols that stop first is the same symbol (in a decorative symbol having a plurality of effective lines). A combination of jackpot symbols that suggests to the player that the jackpot will be a big win depending on the display result of the symbols that are the same symbol on any active line) Is a display that makes a player expect the game, and is a type of entertainment production. An interesting effect is that a predetermined symbol represented by reach is displayed on the display screen of the decorative symbol display device 42 in the middle of variable display, a specific sound is output from a speaker, or a vibration motor is used. This is an effect that causes the player to expect that the display result after the change display will be a big hit with the change display, such as vibrating the game ball launch handle 18.

  The stop pattern selection counter C3 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start port 33. .

The variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). For example, the variation type counter CS3 is incremented by 1 within a range of 0 to 162, for example, and reaches a maximum value (that is, 162) and then returns to 0.
The variation type counter CS1 determines a rough symbol variation mode such as a reach type such as normal reach, super reach, premium reach, etc., and the variation type counter CS2 further refines a symbol such as normal reach A, normal reach B, etc. The variation mode is determined, and the variation type counter CS2 determines, for example, the addition / subtraction of the variation time in the case of a slip stop variation. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 to CS3.

  The counters CS <b> 1 to CS <b> 3 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the counters CS1 to CS3 are acquired when determining the variation pattern at the start of variation of the special symbol by the special symbol display device 38 and the decorative symbol display device 42.

  Next, a counter group related to normal symbols will be described. The counter group related to the normal symbol includes a winning random number counter C4 used for winning lottery and an initial value random number counter CINI2 used for setting an initial value of the winning random number counter C4.

  The hit random number counter C4 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. The counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 701 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, the second starting port 34 is provided. The value of the hit random number counter C4 is stored in accordance with the passing of the game ball.

  Next, the specific contents of the winning random number counter C4 and the initial value random number CINI2 will be described in detail. The winning random number counter C4 is, for example, incremented by 1 within a range of 0 to 250, and returns to 0 after reaching the maximum value (that is, 250). When the winning random number counter C4 makes one round, the value of the winning initial value random number counter CINI2 at that time is read as the initial value of the winning random number counter C4. The initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the winning random number counter C4 (value = 0 to 250), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The hit random number counter C4 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the second start port 34. . The number of random number values hit by the hit random number counter C4 is 149, and the value is “5 to 153”.

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, the big hit random number counter C1, the stop pattern selection counter C3, the hit random number counter C4, and the variation type counters CS1 to CS3 are all different prime numbers and are not synchronized in any case. It is desirable to leave.

  Next, each control process executed by the MPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. 15 to 21. The MPU 501 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 milliseconds (hereinafter referred to as “ms”)). And an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 19 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 501 of the main controller 261 every 2 ms, for example. In the timer interruption process, first, reading process of various winning switches is executed (S601). That is, the state of various switches (except for the RAM erase switch) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI1 and the hit initial value random number counter CINI2 are updated (S602). Specifically, the initial value random number counter CINI1 and the winning initial value random number counter CINI2 are each incremented by 1 and cleared to 0 when the counter values reach the maximum values (738 and 250 in the present embodiment, respectively). . The updated values of the counters CIN1 and CIN2 are stored in the corresponding buffer areas B4 and B9 of the RAM 503.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2, the stop pattern selection counter C3 and the hit random number counter C4 are updated (S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, the stop pattern selection counter C3, and the hit random number counter C4 are each incremented by 1 and their counter values are maximum values (738, 9 in the present embodiment, respectively). , 238, 250) is cleared to 0 respectively. Then, the updated values of the counters C1 to C4 are stored in the corresponding buffer areas B1 to B4 of the RAM 503. Next, a start winning process associated with winning in the start port 33 is executed (S604). Thereafter, a firing solenoid control signal, a ball feed solenoid control signal, and the like are output to the firing control device 312 to execute a firing control process (S605).

  This start winning process will be described with reference to the flowchart of FIG. First, it is determined whether or not the game ball has won the start opening 33 (start winning prize) based on the detection information of the operation opening switch (S701). When it is determined that the game ball has won the start opening 33 (S701: Yes), it is determined whether or not the number N of the operation reserved balls of the special symbol display device 42 is less than the upper limit value (4 in the present embodiment). (S702). If there is a prize at the start port 33 and the number of balls with an operating reserve N <4 (S702: Yes), the number of operating reserve balls N is incremented by 1 (S703), and the jackpot random number counter updated at the step S703 is further added. Each value of C1, jackpot symbol counter C2 and stop pattern selection counter C3 is stored in the first area among the empty reserved areas in the reserved ball storage area 700 of the RAM 503 (S704). On the other hand, if there is no winning at the starting port 33 (S701: No), or even if there is a winning at the starting port 33, if the number of suspended balls N <4 is not satisfied (S702: No), each of S703 and S704 The process is skipped and the start winning process is terminated. After the start winning process is completed, the MPU 501 once ends this timer interrupt process.

  FIG. 21 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 501 of the main controller 261 when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 542 in the power failure monitoring device 540 outputs the power failure signal SG1 to the NMI terminal of the MPU 501 in the main control device 261, and the MPU 501 executes The internal control is interrupted and the NMI interrupt process is started. The NMI interrupt process in the present embodiment will be specifically described. The MPU 501 sets power-off occurrence information (specifically, sets a power failure flag to logic “1”) (S801). When the power failure flag is logic “1”, it indicates that the power supply is cut off (power failure), and when the power failure flag is logic “0”, it indicates that the power supply is not in the power interruption (power failure) state. In the following description, “power interruption occurrence information” means a power failure flag.

  Note that the NMI interrupt processing program of FIG. 21 is stored in the ROM 502 of the main controller 261. During the predetermined time after the power failure signal SG1 is output, the backup power is supplied from the power supply device 313 via the power failure monitoring device 540 so that the processing of the main control device 261 can be executed. An NMI interrupt process is executed.

  After the NMI interrupt process is performed, the process returns to the normal process. During the normal process, as described later, the process is executed up to the final process program. When disconnection occurrence information is set, the process proceeds to power failure processing. In this way, in the event of a power failure, the NMI interrupt processing is set only for the power failure flag, the normal processing is executed up to the final processing program, the power off occurrence information setting is confirmed, and the processing proceeds to power failure processing. Can be simplified.

  The NMI interruption process is also executed in the payout control device 311 in the same manner, and from the power supply unit so that the payout control device 311 can execute the process for a predetermined time after the power failure signal SG1 is output. The same applies to power supply.

  FIG. 15 is a flowchart showing a main process executed by the MPU 501 in the main controller 261. This main process is started by a reset at power-on. In the main process, first, an initial setting process associated with power-on is executed (S101). Next, in order to wait for the payout control device 311 and the sub control device 262 to become operable, a wait process (for example, about 1 second) is executed (S102). After the wait, access to the RAM 503 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch is turned on (specifically, whether or not a RAM erase signal is input from the power supply monitoring device) (S104), and if it is turned on (S104: Yes), the process proceeds to S113. On the other hand, if the RAM erasure switch is not turned on (S104: No), it is further determined whether or not the power-off occurrence information is set in the RAM 503 (S105), and if not set (S105: No). Also in this case, the process proceeds to S113. If the occurrence information of power interruption is set (S105: Yes), the RAM determination value is calculated (S106), and the calculated RAM determination value is not normal (S107: No), that is, the calculated RAM determination is performed. If the value does not match the RAM judgment value stored when the power is turned off, the data stored in the RAM (referred to as data in the RAM) has been destroyed. In such a case as well, the process proceeds to S113. As described above, the RAM determination value is a checksum value at a work area address of the RAM 503, for example. Instead of the RAM determination value, the validity of the RAM data may be determined based on whether or not the keyword written in a predetermined area of the RAM 503 is correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch. Therefore, if the RAM erase switch has been pressed, the routine proceeds to RAM initialization processing (S113). Similarly, when the information on occurrence of power interruption is not set, or when abnormality of the RAM data is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 503 (S113 to S117). To do. That is, in the RAM initialization process from S113, the used area of the RAM 503 is cleared to 0, and the initial value of the RAM 503 is set (S113). Next, a payout initialization command is transmitted to the payout control device 311 (S114), then a command at power-on is transmitted (S115), and the counter and timer are initialized (S116). Thereafter, an interrupt is permitted (S117), and the process proceeds to normal processing described later.

  On the other hand, if the RAM erasure switch is not turned on (S104: No), the information about occurrence of power interruption is set (S105: Yes), and the RAM judgment value (checksum value etc.) is normal (S107). : Yes), the process proceeds to S108, and the information on the occurrence of power interruption is cleared (the power failure flag is set to “0”). Next, a payout return command is transmitted to the payout control device 311 (S109), and then a return command for returning the sub-side control device to the gaming state at the time of power-off is transmitted (S110). The counter and timer are initialized (S111). Thereafter, the interrupt is permitted (S112), and the process proceeds to normal processing described later.

  Next, normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, each process of S201 to S210 is executed as a periodic process with a period of 4 ms, the power failure flag is monitored in the remaining time process, and the process of power interruption (S212 to S216) is executed.

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. In addition, when the decorative symbol display device 42 displays the variation of the decorative symbol, a variable pattern command (a command relating to a symbol variation mode such as normal reach, super reach, premium reach, etc.), a decorative symbol stop symbol code information designation command (specific per designation, non-specific designation) Specific hit designation or out-of-order command, hereinafter abbreviated as “decoration stop symbol code information designation command”), production command (including production time addition designation command, etc.) production stop command (both confirmation command) Or the like) to the sub-control device 262.

  Next, each value of the variation type counters CS1 to CS3 is updated (S202). Specifically, the variation type counters CS1 to CS3 are incremented by 1, and are cleared to 0 when their counter values reach the maximum value (198 in this embodiment). Then, the updated values of the variation type counters CS1 to CS3 are stored in the corresponding buffer area of the RAM 503. Next, a prize ball counting signal, a payout abnormality signal, and a lower pan full signal received from the payout control device 311 are read (S203), and a special symbol change process for performing a special symbol change display by the special symbol display device 38 is executed. (S204). By this special symbol variation processing, in addition to jackpot determination and special symbol variation pattern setting, a variation pattern command for decoration symbol display effect, a decoration stop symbol code information designation command, and an effect time addition designation command Decisions are also made. Details of the special symbol variation process will be described later with reference to FIG.

After the special symbol variation process is finished, a big prize for opening or closing the big prize opening of the variable prize winning device 32 in the case of a big prize other than the non-announcement style certainty change (ordinary big prize, announcement style certainty big hit) A mouth opening / closing process is executed (S205). In other words, the main prize winning opening 61 is opened for each round in the big hit state, and it is determined whether the maximum opening time of the main big winning prize opening 61 has elapsed or whether a predetermined number of game balls have been won in the main big winning prize opening 61. When either of these conditions is satisfied, the main prize winning opening 61 is closed. This is repeated for a predetermined number of rounds. Note that this pachinko machine does not have a specific area (V zone) for continuous opening of the big prize opening. Therefore, in the big hit state, it does not end in the middle of the predetermined number of rounds, and always makes a predetermined round. All the numbers are to be executed.
Note that, in the case of non-notification mode probability change, the opening process of the main prize winning opening 61 is not performed, and instead, the opening process of the subsidiary big winning opening 501 is performed (S206).

  After completion of the special symbol variation process, a special prize opening / closing process for opening or closing the special prize opening of the variable prize winning device 32 in the case of a big prize other than the sudden probability change (normal jackpot, probability variation bonus) Execute (S205). That is, the big winning opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening has elapsed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. This is repeated for a predetermined number of rounds. This pachinko machine does not have a specific area (V zone) for continuous opening of the main winning prize opening. Therefore, in the big hit state, it does not end in the middle of the predetermined number of rounds and is always predetermined. All rounds are executed.

  Next, in step S207, normal symbol display control by the normal symbol display device 41 is executed. Briefly, the value of the hit random number counter C4 is acquired each time on the condition that the game ball has passed through the second starting port 34, and the display lamps 41a and 41b of the normal symbol display device 41 are used. Normal symbol variation display is implemented. Then, when the normal symbol lottery is performed based on the value of the winning random number counter C4 and the normal symbol hit state (a state where “◯” is displayed) is reached, the first start port 33 is opened for a predetermined time (S208).

  Next, it is determined whether or not the information on occurrence of power interruption has been set (S209). If it has been set (S209: Yes), the process proceeds to S213, interrupt inhibition is set (S213), and the power Is transmitted to another control device (S214), and then the output of the control signal is stopped (S215). Next, a RAM determination value is calculated and stored (S216). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Thereafter, access to the RAM 503 is prohibited (S217), and the infinite loop is continued until the power supply is completely shut down and the processing cannot be executed.

  If the power-off occurrence information is not set (S209: No), the process proceeds to step S210, whether or not the next normal process execution timing has been reached, that is, a predetermined time (from the start of the previous normal process) In this embodiment, it is determined whether or not 4 ms) has elapsed (S210). If the predetermined time has already elapsed (S210: Yes), the process returns to step S201.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal process (S210: No), the initial value is within the remaining time until the predetermined time is reached, that is, until the next normal process is executed. The random number counter CINI1, the hit initial value random number counter CINI2, and the variation type counters CS1 to CS3 are repeatedly updated (S211 and S212). First, the initial value random number counter CINI1 and the hit initial value random number counter CINI2 are updated (S211). Specifically, the counters CINI1 and CINI2 are each incremented by 1 and cleared to 0 when their counter values reach the maximum values (738 and 250 in this embodiment). Then, the updated values of the counters CINI1 and CINI2 are stored in the corresponding buffer areas B4 and B9 of the RAM 503, respectively. Next, the counter variation type counters CS1 to CS3 are updated (S212). Specifically, each of the variation type counters CS1 to CS3 is incremented by 1 and cleared to 0 when the counter values reach the maximum value. Then, the update values of the variation type counters CS1 to CS3 are stored in the corresponding buffer areas B5, B6 and B7 of the RAM 503, respectively.

  Thus, since the execution time of each process of S201-S210 changes according to the state of the game, the remaining time until the next execution timing of the normal process is not constant and varies. Therefore, the initial value random number counter CINI1 (that is, the initial value of the big hit random number counter C1) and the hit initial value are repeatedly executed by repeatedly updating the initial value random number counter CINI1 and the hit initial value random number counter CINI2 using the remaining time. The random number counter CINI2 (that is, the initial value of the hit random number counter C4) can be updated at random. Similarly, the variation type counters CS1 to CS3 can be updated at random.

  Next, the special symbol variation process (S204) will be described with reference to the flowchart of FIG. In the special symbol variation process, first, it is determined whether or not a big hit is currently being made (S401). The jackpot includes a jackpot game displayed on the decorative symbol display device 42 when a jackpot is won and a predetermined time after the jackpot game is over. As a result of the determination, if it is a big hit (S401: Yes), this processing is terminated as it is.

  If it is not a big hit (S401: No), it is determined whether or not the special symbol is being displayed by the special symbol display device 38 (S402). If the special symbol is not being displayed (S402: No), It is determined whether or not the number N of actuated balls on the special symbol display device 38 is greater than 0 (S403). If the number N of active suspension balls is 0 (S403: No), this process is ended as it is. If the number of the operation reservation balls N> 0 (S403: Yes), the operation reservation ball number N is decremented by 1 (S404), and the data stored in the storage ball storage area 700 is shifted (S405). This data shift process is a process for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area 700 to the execution area side. The reserved first area → the execution area, the reserved second area Specifically, data in each area is shifted, such as a hold first area, a hold third area, a hold second area, a hold fourth area, and a hold third area. After the data shift process, a special symbol variation start process is executed (S406). The variation start process will be described later with reference to FIG.

  In the process of S402, when the variation display of the special symbol is being performed (S402: Yes), it is determined whether or not the variation time has elapsed (S407). The variation time of the special symbol is determined according to the variation pattern of the special symbol. When the variation time has not elapsed (S407: No), the display symbol of the special symbol is updated (S408), and this process is performed. finish. Here, “update the display symbol of the special symbol” means that the special symbol display lamps 38a and 38b are changed to a lighting state different from the current lighting state. For example, the case where the lighting color of the special symbol display lamps 38a and 38b is changed is applicable. When the variation time has elapsed (S407: Yes), the special symbol stop symbol is set as the display symbol (S409). Here, “special symbol stop symbol is set as display symbol” means that special symbol display lamps 38a and 38b are lit in a stop symbol (the lighting color of the lamp corresponding to specific hit, non-specific hit, and off respectively). It means to do. Next, an effect pattern stop command is set (S410), and this process ends.

  Next, the variation start process will be described with reference to the flowchart of FIG. In the fluctuation start process (S406), first, it is determined whether or not a big hit is made based on the value of the big hit random number counter C1 stored in the execution area of the reserved ball storage area 700 (S501). Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “373,727” is the winning value among the numerical values 0 to 738 of the jackpot random number counter C1 at the normal low probability, and “59, 109, 163, 211, 263, 317, 367, 421, at the high probability. "479, 523, 577, 631, 683, 733" is the winning value.

  When it is determined that the game is a jackpot (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area 700, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol (either a specific symbol or a non-specific symbol) is set as a stop symbol (S502). Next, the jackpot effect pattern is determined by checking the count values of the variation type counters CS1 and CS2 (S503).

  Next, the value of the variation type counter CS3 is confirmed to determine the effect time addition (S504). Next, an effect pattern designation command (also referred to as a variation pattern designation command) is set according to the jackpot effect pattern determined in step S503 (S505), and a decoration stop symbol code information command is set according to the stop symbol set in step S502. Set (S506), and when the effect time addition is determined in step S504, an effect time addition designation command is set (S506). In this way, in steps S501 to S507, an effect pattern designation command, a decoration stop symbol code information command, and an effect time addition designation command in the case of a big win are set.

If it is determined in step S501 that the game is not a big hit (S501: No), the off symbol is set as a stop symbol (S508). An off-stage production pattern is determined (S509). Then, an effect pattern designation command, a decoration stop symbol code information command, and an effect time addition designation command in the case of not being a big hit are set by the processing of steps S504 to S507, respectively.
In the case of non-notification mode probability variation (sudden probability variation), as described above, the special symbol is a stop symbol per probability variation, but the decorative symbol stop symbol is a stop symbol in the case of detachment. Accordingly, the decoration stop symbol code information command in step S506 is a command with a content for designating a disengagement. In other words, in the case of a normal jackpot or notification mode probability variation (normal probability variation per unit), the decoration stop symbol code information command in step S506 includes non-specific (ordinary per unit) designation and specific (per unit probable per unit) designation, respectively. However, in the case of non-notification mode probability change, the command is a command with a designation of detachment in order to obtain a stop symbol similar to that in the case of losing. Whether or not it is a non-notification mode probability change is determined based on the value of the jackpot symbol counter C2. That is, among the values 0 to 9 of the jackpot symbol counter C2, as described above, “0, 4, 5, 6” is a normal jackpot value, and “1, 2, 3, 7” is a notification mode probability variation. Since it is a value and “8, 9” is a non-notification aspect probability variation value, it can be determined whether or not it is a non-notification aspect probability variation based on the value of the jackpot symbol counter C2.

  In the case of non-notification mode probable change, it is not limited to the command with the content of the designation of disengagement so that the stop pattern is the same as in the case of the disengagement, for example, “1, 2, 3” You may make it use the command which designates the exclusive symbol per non-notification mode certain change.

  Here, based on FIG. 29, the overall flow up to the processing for sudden probability change will be described. First, determine if a jackpot has occurred. If the jackpot has not occurred (S1600: No), the jackpot processing is not performed and the normal processing is continued. If the jackpot has occurred (S1600: Yes), it is determined whether the jackpot is per probability change. When it is not per probability fluctuation (S1602: No), normal hit processing is performed (S1603). In the case of per probability change (S1602: Yes), it is further determined whether or not the jackpot is not notified. When it is not a jackpot non-notification mode (S1604: No), a normal probability changing process is performed in order to make the player recognize per probability change (S1605). In the case of the jackpot non-notification mode (S1604: Yes), instead of the normal probability changing process, it is only necessary to open the secondary big prize opening (S1607). For other effects, normal effect processing is performed (S1607, S1608). By performing such processing, it is possible to make it difficult for the player to recognize even when a probability change per occurrence occurs in the jackpot non-notification mode.

  Next, with reference to FIGS. 22 and 23, each process executed by the MPU 550 of the sub-control device 262 will be described. FIG. 22 is a flowchart showing the main process of the sub-control device 262. This main process is activated by a reset at power-on.

  The main process of the sub-control device 262 first executes an initial setting process associated with power-on (S911), initializes I / O and timer, and sets each interrupt such as a timer interrupt. Next, it is determined whether or not all the power-off processes have been completed, that is, whether all the lamps are turned off or the speaker is muted (S912). When all the power-off processes are completed (S912: Yes), the process proceeds to S914. If all the power-off processes have not been completed (S912: No), the RAM 552 may be destroyed, so it is determined whether or not the RAM 552 is destroyed (S913). Specifically, RAM destruction check data is preset in the RAM 552, and the determination is made based on the RAM destruction check data. When it is determined that the RAM 552 is not destroyed (S913: No), the process proceeds to step S917. On the other hand, when it is determined that the RAM 552 is destroyed (S913: Yes), a read / write check is performed on each area of the RAM 552 (S914), and whether or not the RAM 552 functions normally based on the result of the read / write check is determined. It discriminate | determines (S915). When the RAM 552 is not normal (S915: No), a predetermined lamp is turned on to notify the RAM abnormality (S921).

  On the other hand, if the RAM 552 is normal (S915: Yes), RAM destruction check data is set in the RAM 552 (S916). Next, it is determined whether or not the power is turned on after the power is turned off (S917). If the power is not turned on after the power is turned off (S917: No), the area other than the uninitialized area in the RAM 522 is cleared (S918). Thereby, all the commands transmitted from the main controller 261 other than the power command are cleared. Next, interrupts such as timer interruption and command reception processing from the main control device 261 are permitted (S919). Next, the initial value of the RAM 522 is set (S920), and thereafter, the process proceeds to normal processing described later. On the other hand, if the power is turned on after the power is turned off in step S917, the process proceeds to step S919.

  Next, normal processing of the sub-control device 262 will be described with reference to FIG. First, it is determined whether 1 ms or more has elapsed (S1031). If it is before 1 ms has elapsed (S1031: No), the random numbers for generating the off symbol, the jackpot symbol, the notice symbol, etc. related to the decorative symbol are updated (S1040). Specifically, a jackpot decorative symbol (for a specific symbol) counter, a jackpot decorative symbol (for a non-specific symbol) counter, a reach decorative symbol counter, a complete off-decorative symbol counter, a symbol symbol for effects such as a warning symbol, etc. are provided. The counter values associated with these decorative symbols are updated. Note that the values of these counters are updated randomly. That is, by using the value of the R register built in the MPU 550, the values of these counters are updated at random. That is, when updating these counters, the lower 2 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, “6” is subtracted to determine the current value.

  After the random number update process (S1040), a command is received from the main controller 261, and a process corresponding to each command is performed (S1041). Here, if the command from the main control device 261 is a command related to the display of decorative symbols, the command to the display control device 45 is edited based on the command, and the edited command is sent to the display control device 45. Send. More specifically, the display command from the main controller 261 includes a variation pattern designation command (a command generated based on the stop pattern selection counter C3 and the variation type counters CS1 and CS2, and includes normal reach, super reach, A command for designating a pattern variation mode such as premium reach), a decoration stop symbol code information command (a command for specific designation, designation for non-specific designation, or designation for removal), a production command (generated based on a variation type counter CS3) Command for changing the change time), stop command (decorative symbol stop command, so-called confirmation command), and the like. On the other hand, the sub-control device 262 transmits the variation pattern designation command from the main control device 261 as it is to the display control device 45, but the decoration stop symbol code information command is specific for each specific designation, non-specific designation, and out-specification. Edit the decorative command (stop symbol) into the determined command. In this editing, the stop symbol is determined by the decorative symbol counter in the MPU 550. In addition, the production command from the main control device 261 is edited into a command including designation of various productions in addition to the change of the variation time. Then, the sub control device 262 transmits these commands to the display control device 45. As a result, the display control device 45 analyzes the received command, generates an image of a decorative symbol in accordance with the command, and outputs the image to the decorative symbol display device 42, whereby the decorative symbol display device 42 displays a predetermined effect display. In this way, the variable display is executed.

Thereafter, it is confirmed whether or not the RAM 552 is destroyed (S1042). If it is not destroyed (S1042: No), the process returns to step S1031. If it is destroyed (S1042: Yes), an infinite loop process is performed.
On the other hand, in step S1031, if 1 ms or more has elapsed (S1031: Yes), a lamp lighting pattern corresponding to the effect pattern of the decorative symbol display device 42 is output to the effect lamp 811 and the effect lamp 811 is turned on ( S1032). The creation of the lamp lighting pattern is specifically performed by the process of step S1037 described later. Next, a predetermined lamp is turned on for 30 seconds by a power-on command, and notification is made (S1033). Next, a customer waiting effect command for switching between the title of the decorative symbol and the still image is generated and transmitted to the display control device 45 (S1034). Next, when displaying the reserved number of special symbols on the decorative symbol display device 42, a command for generating the reserved number display is generated and transmitted to the display control device 45 (S1035).

  Next, the input operation of the effect button 79 is confirmed. When there is an input operation, an effect command is generated so that a predetermined effect corresponding to the effect button 79 is displayed on the decorative symbol display device 42, It transmits to the display control apparatus 45 (S1036). Next, the lamp lighting pattern corresponding to the effect pattern of the decorative design display device 42 is edited (S1037), the sound pattern of the speaker 810 corresponding to the effect pattern of the decorative design display device 42 is edited, and the sound pattern is displayed on the speaker 810. It outputs (S1038).

Next, various time managements for executing the display effect of the decorative symbol display device 42 are performed (S1038). Thereafter, the process returns to step S1031 via steps S1040, S1041, and S1042.
In this way, the sub-control device 262 is based on the sounding control of the effect speaker 810 and the lighting (flashing) control of the effect lamp 811 according to the variation display of the decorative design, and the command from the main control device 261. Edit command to display control device 45 and send to display control device 45

  Next, display control in the display control device 45 will be described. FIG. 24 is a flowchart showing display control processing executed by the MPU 521 in the display control device 45. The MPU 521 executes display control of the decorative symbol display device 42 while processing various commands provided from the sub-control device 262 according to the procedure shown in FIG.

  First, it is determined whether or not a display command has been received from the sub-control device 262 (S1151). If not received (S1151: No), it waits until some command is received. When a display command is received (S1151: Yes), the contents of the display command are stored in the RAM 523 (S1152). Next, various arithmetic processes such as generating an internal command for the image controller 526 are started based on the information stored in the RAM 523 (S1153). As a result, the image controller 526 starts drawing processing in response to a command (internal command) from the MPU 521. It should be noted that symbol display is continued under the cooperation of the MPU 521 and the image controller 526 until a display command is received after the display command is received. Meanwhile, the MPU 521 performs the control of the image controller 526 and the command reception process shown in FIG. 18 in parallel.

  Thereafter, it is determined whether or not a confirmation command has been received from the sub-control device 262 (S1154). Then, on the condition that the confirmation command has been received, the process proceeds to step S1155, and the image controller 526 is instructed to display the confirmation with the stop symbol. As a result, the image controller 526 displays the changed symbol as a stop symbol. In this way, one round of display processing is performed from the start of change of the symbol to the stop of change (definite display). The display control device 45 is controlled by the sub-control device 262 at the time of starting and stopping the change of the symbol, but the continuous change of the symbol during that time is autonomous by the MPU 521 and the image controller 526 in the display control device 45. Is secured by proper image control.

  Next, payout control executed by the MPU 511 in the payout control device 311 will be described with reference to FIG. FIG. 25 is a flowchart showing the main process of the payout control device 311. This main process is activated by a reset at power-on.

  First, initial setting processing accompanying power-on is executed (S1201). Specifically, a predetermined value set in advance in the stack pointer and an interrupt mode are set. Next, RAM access is permitted (S1202), and an external interrupt vector is set (S1203).

  Thereafter, it is determined whether or not the information on occurrence of power interruption is stored in the RAM 513 (S1204). If not stored (S1204: No), the process proceeds to S1210. If the occurrence information of the power interruption is stored in the RAM 513 (S1204: Yes), the RAM determination value is calculated (S1205), and the calculated RAM determination value is not normal (S1206: No), that is, the calculated RAM determination. If the value does not match the RAM determination value stored when the power is turned off, the data stored in the RAM 513 has been destroyed. In this case as well, the process proceeds to S1210. As described above, the RAM determination value is a checksum value at a work area address of the RAM 513, for example. Instead of the RAM determination value, the validity of the data stored in the RAM 513 may be determined based on whether or not the keyword written in a predetermined area of the RAM 513 is correctly stored.

  In the RAM initialization process from step S1210, the used area of the RAM 513 is cleared to 0 (S1210), and the initial value of the RAM 513 is set (S1211). Thereafter, the MPU 511 peripheral device is initialized (S1208), an interrupt is permitted (S1209), and the process proceeds to a payout control process described later.

  On the other hand, if the power-off occurrence information is set (S1204: Yes) and the RAM judgment value (checksum value etc.) is normal (S1206: Yes), the process at the time of power recovery (at the time of power-off restoration) Process). That is, the initial value of the RAM 513 is set (S1207), the MPU511 peripheral device is initialized (S1208), the interrupt is permitted (S1209), and the process proceeds to a payout control process described later.

Next, payout control processing will be described with reference to the flowchart of FIG. This payout control process is executed following the main process of the payout control device 311. In the payout control process, first, a command from the main controller 261 is acquired and stored as the total number of winning balls (S1301). Here, if the command from the main control device 261 is a regular command, all payouts are permitted. If the command from the main control device 261 is a prize ball command, a payout return command, or a payout initialization command, processing corresponding to the command is performed.
Next, it is determined whether or not a payout permission command transmitted from the main controller 261 is received (S1302: No). When the payout permission command is received (S1302: Yes), the state return operation is executed when it is determined that the state return operation is started as a result of checking the state return switch 321 (S1303).

  Thereafter, the setting of the lower plate full state or the lower plate full state is executed according to the change in the state of the lower plate 15 (S1304). That is, when the lower plate 15 is full based on the detection signal of the lower plate full switch, when the lower plate is full, the setting of the lower plate full state is executed. , Set the lower pan full release state. Further, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change of the tank ball state (S1305). In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration. Thereafter, the presence / absence of a notification state is determined, and if there is a notification state, notification is made by a 7-segment LED provided in the payout control device 311 (S1306).

  Next, a prize ball payout process is executed by each process of S1307, S1308, and S1315. That is, if the prize ball is not paid out and the total number of prize balls stored in S1301 is not 0 (S1307: No, S1308: No), the prize ball control process shown in FIG. 27 is started (S1315). . On the other hand, if the prize ball cannot be paid out (S1307: Yes) or if the total number of prize balls is 0 (S1308: Yes), the process proceeds to the lending and payout process. The prize ball control process will be described later.

  In the lending payout processing of S1309, S1310, and S1316, if the lending payout request is not received from the card unit and the lending payout request is received from the card unit (S1309: No, S1310: Yes), it is shown in FIG. The lending control process is started (S1316). The ball rental control process will be described later.

  On the other hand, if it is not in the lending-out state of the lending ball and has not received a lending-out request from the card unit (S1309: No, S1310: No), or if it is in the lending-out state of lending (S1309: Yes) ), Vibrator control (vibrating motor control) is executed for releasing the ball clogging state (S1311). Thereafter, it is determined whether or not a power failure has occurred (S1312). If a power failure has not occurred (S1312: No), the process returns to step S1301. If a power outage has occurred (S1312: Yes), information on the occurrence of power interruption is set (S1313), a RAM determination value is created (S1314), and then an infinite loop is entered to wait for input of a reset signal.

  Next, the prize ball control process shown in FIG. 27 will be described. In the winning ball control process, first, the payout motor 358a is driven to rotate in the forward direction, and the paying of the winning ball is executed (S1401). Whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (S1402). If not normal (S1402: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a. The stop process is executed (S1403), and then the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal (S1402: Yes), it is determined from the detection result of the payout count switch whether the game ball is normally counted (S1404). If the game ball count is not normal (S1404: No), the payout motor 358a is driven to execute the retry process and the payout motor 358a is stopped (S1405). Thereafter, the payout control process of FIG. Return.

  Further, if the game ball count is normal (S1404: Yes), it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout is completed (S1406). If completed (S1406: Yes), a stop process of the payout motor 358a is executed (S1407), and then the process returns to the payout control process of FIG. On the other hand, if the payout has not been completed (S1406: No), the process returns to the payout control process of FIG.

  Next, the ball rental control process shown in FIG. 28 will be described. In the ball lending control process, first, the payout motor 358a is driven to rotate in the forward direction to pay out a lending ball (S1501). Whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (S1502). If not normal (S1502: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a. The stop process is executed (S1503), and then the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal (S1502: Yes), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (S1504). If the game ball count is not normal (S1504: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped (S1505). Thereafter, the payout control process of FIG. Return.

  Further, if the game ball count is normal (S1504: Yes), it is determined whether or not the game ball count by the payout count switch has reached a predetermined number (25) and the payout is completed ( If the payout has been completed (S1506: Yes), the payout motor 358a is stopped (S1507), and then the payout control process of FIG. 26 is returned. On the other hand, if the payout has not been completed (S1506: No), the process returns to the payout control process of FIG.

[Second form]
In the first embodiment, since the player makes an effect that makes it difficult for the player to recognize per probability change, the player ends the game without recognizing it as it is. The player's interests may be lost. Therefore, in the second mode, in order not to impair the player's profit, only in the state of sudden probability change, “there is no state where there is a lottery lottery holding ball” and “the player releases his hand from the game ball launching handle” When the condition is satisfied, the probability sudden hit state is suddenly notified from the speaker (notification by voice, etc.).

Specific contents will be described below.
FIG. 30 is a functional block diagram of the main control device 261 and the sub-control device 262. FIG. 30 mainly shows a functional configuration for executing the notification processing, and a configuration not related to the notification processing execution function is omitted. I draw. The main control device 261 determines whether or not there is a reserved ball presence determination unit 1000 that determines whether or not a big hit lottery holding ball exists, a notification processing determination unit 1002 that determines whether or not to perform notification processing, and a notification command. And a notification command generation unit 1004 for generation. The notification processing determination unit 1002 is provided with a determination output signal from the reserved ball presence determination unit 1000 and a detection output signal from the touch sensor 1001. In addition, the notification processing control unit 1002 is connected to a sudden probability change state flag F10 so that it can be determined whether or not a sudden probability change state is in effect based on the logical value of the sudden probability change state flag F10. If the sudden probability change state flag F10 is set to logic "1", it indicates that the sudden probability change state is in effect, and if the sudden probability change state flag F10 is set to logic "0". Suddenly, it is not in a probable state.

  The holding ball presence / absence determination unit 1000 determines whether or not there is a holding ball depending on whether or not the data is stored in the four holding ball storage areas 700, and outputs a high level signal when there is no holding ball. When there is a holding ball, a low level signal is output. The touch sensor 1001 outputs a low level signal when the player is touching the game ball launch handle, and outputs a high level signal when the player releases the hand from the game ball launch handle. Is output.

  On the other hand, the sub control device 262 receives the command transmitted from the main control device 261 and analyzes the content of the received command, and causes the speaker 810 to ring when the received command is a notification command. A sound output control unit 1005 that performs sound output control.

  Next, the notification process will be described with reference to FIGS. 31 and 32. FIG. 31 is a flowchart showing the notification process 1, and FIG. 32 is a flowchart showing the notification process 2. The notification process 1 in FIG. 31 is a process performed in the main control apparatus 261, and the notification process 2 in FIG. 32 is a process performed in the sub-control apparatus 262.

  With reference to FIG. 31, the notification process 1 performed in the main controller 261 will be described. First, it is determined whether or not the player has released his / her hand from the game ball launch handle (step S2000). Specifically, it is determined whether or not the output from the touch sensor 1001 has changed to a high level. When the output from the touch sensor 1001 becomes a high level, it is determined that the player has released his / her hand from the game ball launching handle, and the process moves to step S2001, where it is determined whether or not there is no reserved ball. The determination as to whether or not there is a holding ball is made based on whether or not the output from the holding ball presence / absence determination unit 1000 has changed to a high level. If there is no holding ball (S2001: Yes), it is determined whether or not the sudden hit state with sudden probability change is in accordance with the logical value of the sudden probability change hit state flag F10 (S2002). When the sudden probability change state flag F10 is the logic “1”, since the sudden change state with sudden probability change is in progress, the process proceeds to step S2003, a notification command is generated, and this notification command is transmitted to the sub-control device 262. Thereafter, the process ends. If the player has not released his / her hand from the game ball launching handle in step S2000 (S2000: No), if the player has a holding ball in step S2001 (S2001: No), or if the player is not in a sudden hit state with probable change in step S2002. (S2002: No) ends the processing.

  Next, with reference to FIG. 32, the notification process 2 performed in the sub control device 262 will be described. It is determined whether a notification command has been input (S2010). That is, when receiving a command from the main control device 261, the command analysis unit 1004 analyzes the contents. When the received command is a notification command, the command analysis unit 1004 gives the notification command to the sound output control unit 1005. As a result, the process moves to step S2011, and the squeaker ringing process is executed. That is, the sound output control unit 1005 outputs an audio signal corresponding to the notification command to the speaker 810, and thereby outputs the audio indicating that the sbeaker 810 is suddenly in the big hit state with probability change. If the received command is not a notification command in step S2010, processing corresponding to the command is executed (S2012).

  In this way, the sudden hit state is suddenly changed from the speaker when the conditions of “there is no holding ball for lottery lottery” and “the player releases his hand from the game ball launching handle” are satisfied only during the sudden hit state. Is notified. As a result, the player who has once left the gaming machine returns to the gaming machine and resumes the game, so that it is possible to suddenly enjoy the benefit of the probable hit state.

  In addition, the conditions for the notification are not limited to this, and for example, notification may be made when a predetermined number (for example, 50 times) of the decorative pattern fluctuates after a sudden probability change state. Further, whether to notify or not may be determined by lottery.

[Third embodiment]
Here, based on FIG. 33 to FIG. 37, the control of the game ball in the special gaming state non-notification mode, the normal time and the notification mode will be described.
This control of the game ball cannot be obtained due to the fact that the profit that was originally enjoyed at the time of the probability variation, for example, the winning due to the operation of the variable winning device cannot be operated as a result of introducing the non-notification mode. It is to be able to enjoy in another form without being noticed by the player.

  Accordingly, lottery means (corresponding to jackpot random number counter C1 and jackpot symbol counter C2) in which lottery with probability variation jackpot, normal jackpot, and off is executed in response to the winning of the game ball at the start port 33, A configuration comprising a display device 42 for displaying a lottery result by the lottery means, a jackpot with probability variation and a main jackpot that is opened when the normal jackpot is reached, and the display at the time of jackpot with probability variation As a display mode displayed by the device 42, from a jackpot notification mode for notifying the player that it is a jackpot state with probability variation, and a jackpot non-notification mode that does not notify the player that the jackpot state with probability variation is described above At the same time, as the above-mentioned big winning opening 6 1, the configuration of the sub winning opening 601 and a main winning opening 61 which controls the function of the special winning opening unless it is operating to be ball entrance does not particularly alternative.

Here, as shown in FIGS. 33 to 36, a wave-like stage 660 is provided above the start opening, and a windmill 464 is provided below the stage 660, and the start opening, here Then, a windmill control mechanism 462 having a windmill 464 for guiding the game ball so as to prevent the game ball from entering the upper start port 33a in a normal state and to enter the ball in the non-notification mode with probability variation jackpot. It is provided.
The wavy stage 660 is provided with concave portions 463 for guiding the game ball on the wave bottoms on both sides of the center of the wavy center.

  Further, the windmill control mechanism 462 has a support shaft 464A of the windmill 464 on the virtual extension line 470 at the center of the recess 463 and on the upper side of the upper start port 33a (the windmill 464 and the support shaft 464A are relative to each other). In a normal state, the tip end side of the support shaft 464A is inclined and displaced in a direction approaching the starter port 33a (see FIG. 35), and the game ball enters the starter port 33a. In the special game state non-notification mode, the ball is restrained and the tip end side of the support shaft 464A is inclined and displaced in the direction away from the starting port (see FIG. 33) to facilitate the entry of the game ball. Yes.

  Further, as shown in FIGS. 34 and 36, the windmill control mechanism 462 includes a solenoid 465 for inclining the winder 464, and the support shaft 464A is provided at the axial center by the solenoid 465. It is rotated around an axis X1 that goes straight and is parallel to the surface of the game board 30. In these drawings, the inclination of the support shaft 464A is drawn largely to help understand the explanation, but in reality, it is 20 ° or less.

  Furthermore, the relationship between the concave portion 463 of the wavy stage 660 and the windmill control mechanism 462 is arranged such that the rotational axis of the windmill 464 is on a virtual extension line at the center of the concave portion. As described above, the windmill 464 is operated so as to be inclined and displaced to at least two positions in the jackpot non-notification mode for guiding the winning to the start port 33a and the other mode for suppressing the winning in reverse. The rotation axis is shifted from the imaginary line extension to the left and right outer sides in the front view shown in FIG. 33 and to the left and right inner sides shown in FIG.

Further, the windmill control mechanism 462 is provided at a predetermined interval on the lateral side of the life nail 467 of the start port 33a so that the game balls guided by the windmill 464 enter the start port with higher probability. Guide nails 466.
One guide nail 466 is arranged in the above description. However, due to the arrangement relationship of the windmill 464, for example, as shown in FIG. 37, the position of the windmill 464 is more than the life nail 467 of the start port 33a. If they are far apart, a plurality of (for example, 4, 5) guide nails 466 may be arranged continuously and at a predetermined interval so that more reliable guidance can be performed.
In FIGS. 33, 35, and 37, 441 and 442 indicate a warp inlet and a warp outlet of the warp passage 440A, respectively.

(Function)
As described above, by using the wave-like stage having the existing game board surface structure and arranging the windmill control mechanism 462 below it, when the big hit non-notification mode is output by the lottery means C2, the result is received. The solenoid 465 is actuated, and the support shaft 464A of the windmill 464 tilts the windmill 464 (arranged on the right side as viewed from the front) to the right as shown in FIG. As shown in FIG. 5, the game ball that is displaced outward from the center of the recess 463 and dropped while being guided along the center line from the upper recess 463 is surely left of the rotation axis in the front view of the windmill 464. The wind turbine 464 is rotated counterclockwise and guided toward the start port 33a.

At this time, the game ball leaving the windmill 464 collides with the guide nail 466 provided below the windmill 464, and is thereby more reliably guided between the life nails 467 of the start port 33a.
In normal times, as shown in FIG. 36, the wind turbine 464 (disposed on the right side in the front view) has the axis of the support shaft 464A directed inward from the center line of the upper recess 463. As shown in FIG. 35, the game ball that has been tilted from the upper side collides with the right half side in front view of the windmill 464, and guides the game ball to the outside of the right rotation of the windmill 464. In normal times, it is possible to prevent a winning with a high probability of abnormality in the starting port 33a. Thus, while the progress of the jackpot non-notification mode can be made secretly, the profit to be received by the jackpot can be reduced by increasing the winning rate to the start port 33a.

[Fourth form]
The configuration is the same as that of the first embodiment except that the processing per sudden change is slightly different. Specifically, as shown in FIG. 38, a special display process is performed in S1609, and in S1610, a special process of the variable winning device 32 having a pair of opening and closing blades 60 is performed, and other steps (S1600 to S1600). 1608) is the same as the first embodiment.

  Specifically, the special display processing of the decorative symbol display device 42 is, for example, changing the character from the normal time or changing the background color from the normal time. While the color is blue, the background color is purple when the probability changes. The special process of the variable winning device 32 includes changing the time and the number of times the pair of opening / closing blades 60 are opened, changing the lottery time for determining whether the opening / closing blades 60 are opened, and the like. In the form, a lottery is performed to determine whether or not to open the opening / closing blade 60 once every 30 seconds in normal times, and when winning, the opening / closing blade 60 is opened for 0.5 seconds (only once). On the other hand, when the probability is changed, a lottery is performed once every 30 seconds to determine whether to open or close the opening / closing blade 60. When winning, the opening / closing blade 60 is opened (number of times) at 1.0 second intervals. 3). By performing such processing, it is difficult for the player to recognize that a big win has occurred when the sub-winner opening 601 is operated, but the player can be surely recognized that the state has shifted to the probability variation state thereafter.

[Fifth embodiment]
In the above-described three embodiments, the secondary big prize opening 601 and the like are provided in the through gate. However, the present invention is not limited to such a structure. For example, as shown in FIG. The stage 660 may be provided with a sub-large winning opening 710 that can be opened and closed. Even in such a structure, since the stage 660 is not a player's gaze point, even if the secondary big prize opening 710 is activated, it is difficult for the player to recognize that the big hit has occurred. Further, since the gaming machine swings on the stage 660, even if a game ball exists on the stage 660 when the secondary big prize opening 710 is opened, the game ball does not necessarily have the secondary big prize opening 710. It is not always possible to win a prize. Therefore, the game becomes thrilling and the interest of the game is improved.

  The present invention has a probability variation function as a gaming machine, and is a wide range of inventions that can be appropriately applied as long as it has a big prize opening.
