Abstract

PROBLEM TO BE SOLVED: To provide a game machine capable of easily changing design of an opening/closing period in a variable winning device.SOLUTION: A game control CPU 56 excites a solenoid 21B when a round is started (tb1). Thus, a movable piece 20d located at a closing position starts rotating toward a side of an open position. Then, the movable piece 20d reaches the open position and a rotation regulation shaft 314 abuts on a lower end 315a of a rotation regulation groove 315 (tb2). In this case, after the movable piece 20d rebounds to the side of the closing position by the abutting shock, excitation of the solenoid 21B is released and closing control is started at timing (tb3) when the movable piece 20d can be rotated toward the side of the closing position until the movable piece 20d returns to the open position again and rebounding operation is completed.

Description

  The present invention has a movable member in which a game is played by firing a game ball in a game area formed on a game board surface, and the game ball changes into an open state in which a game ball is easy to win and a closed state in which it is difficult to win or is hard to win. The present invention relates to a gaming machine equipped with a variable winning device.

  As this type of gaming machine, a game ball, which is a game medium, is launched into a game area by a launching device, and when a game ball is won in a prize area such as a prize opening provided in the game area, a predetermined number of game balls are prized. There are some (award balls) that are paid out to the player. Furthermore, as a display result of the variable display of the special symbol (identification information) started in the variable display unit based on the winning of the game ball at the start winning opening, a predetermined specific display mode (specific display result) is provided. There is a gaming machine that shifts to a big hit gaming state (specific gaming state) when it is derived and displayed. When a big hit occurs, for example, the big winning opening (one of the winning areas) is opened a predetermined number of times (for example, 16 times), and the game state shifts to a specific gaming state where it is easy to win. And in each open period, if there is a prize for a predetermined number (for example, 10) of the big prize opening, the big prize opening is closed. Hereinafter, the opening period of each special winning opening is referred to as a round.

  In addition, there is a type of winning hole that includes a variable winning ball device that performs an operation from a closed state where a game ball cannot be won to an open state where a game ball can be won when a predetermined condition is satisfied. As an example of such a variable winning ball device, a first opening / closing device capable of opening and closing the first big winning opening by an opening / closing door and a second big winning opening different from the first big winning opening enter the game area side. And a second opening / closing device that can be opened and closed at a higher speed than the opening / closing door of the first large winning opening by a slide plate that can be linearly reciprocated between the advance position that moves forward and the retracted position that retreats into the winning opening. (For example, refer to Patent Document 1).

  As another example of the variable winning ball apparatus, one end is pivotally supported by a rotating shaft orthogonal to the game board and rotates between a closed position for closing the winning opening and an open position for opening the winning opening. There existed what was provided with the movable member provided, for example (refer patent document 2).

JP 2010-104425 A JP 2008-125752 A

  As in the gaming machine described in Patent Document 1, a movable member such as an opening / closing door of the first opening / closing device or a sliding plate of the second opening / closing device is provided so as to be movable between an open position and a closed position. If the movement is restricted by bringing the movable member into contact with the contact plate or the like at the advanced position or the retracted position, the rebound will occur at the open or closed position due to the impact when the contact is made with the contact plate. May occur and the movable member may flutter until it is stably maintained in the open position or the closed position.

  Further, as in the gaming machine described in Patent Document 2, when a movable member or the like whose one end is pivotally supported by a pivot shaft is opened and closed at a high speed, a contact plate or the like in an open position or a closed position Since the impact when it abuts on the surface increases, the fluttering increases and the period until it is stably maintained also increases.

  Thus, due to the fluttering of the movable member in the open position or the closed position, it takes time until the movable member is stably maintained in the open position or the closed position, so that the actual opening / closing period of the movable member can be changed by the designer. Since it becomes longer than the intended opening and closing period and an error is likely to occur between the designed winning rate and the actual winning rate, for example, the opening and closing period of the big winning opening according to the type of the big hit gaming state etc. There was a problem that design changes could not be easily made.

  The present invention has been made paying attention to such a problem, and an object of the present invention is to provide a gaming machine capable of easily changing the design of the opening / closing period in the variable winning device.

The game board 6 is detachably attached to the front frame 101 on the back surface of the glass door frame 102.

  The game board 6 is composed of a plywood board in which the game area 7 is formed on the game board surface (front face) 6a side, and on the back side of the game board 6, a variable display control unit (including a presentation display device 9 and a presentation control board 80). A game board unit 260 to which game parts related to games such as not shown) are assembled is integrally assembled (see FIG. 2).

  Returning to FIG. 1, in the vicinity of the center of the game area 7, there is provided an effect display device (decorative symbol display device) 9 including a plurality of variable display units each variably displaying an effect decorative symbol (effect symbol). ing. The effect display device 9 includes, for example, three variable display portions (symbol display areas) of “left”, “middle”, and “right”. The effect display device 9 variably displays the effect symbol as a decoration (effect) symbol during the variable display period of the special symbol by the first special symbol indicator 8a or the second special symbol indicator 8b. The effect display device 9 that performs variable display of effect symbols is controlled by an effect control microcomputer mounted on the effect control board 80.

  A first special symbol display (first variable display means) 8a for variably displaying a first special symbol as first identification information is provided at a lower right position on the game board 6. In this embodiment, the first special symbol display 8a is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. In other words, the first special symbol display 8a is configured to variably display numbers (or symbols) from 0 to 9. A second special symbol display (second variable display means) 8b for variably displaying the second special symbol as the second identification information is provided above the first special symbol display 8a. The second special symbol display 8b is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the second special symbol display 8b is configured to variably display numbers (or symbols) from 0 to 9.

  In this embodiment, the type of the first special symbol and the type of the second special symbol are the same (for example, both 0 to 9), but the types may be different. The first special symbol display 8a and the second special symbol display 8b each variably display a number (or a two-digit symbol) from 0 to 99 using, for example, two 7-segment LEDs. It may be configured.

  Hereinafter, the first special symbol and the second special symbol may be collectively referred to as a special symbol, and the first special symbol indicator 8a and the second special symbol indicator 8b may be collectively referred to as a special symbol indicator.

  The variable display of the first special symbol is a variable display start condition (for example, after the game ball has won the first start winning opening 13a) after the first start condition, which is the variable display execution condition, is established (for example, When the number of reserved memories is not 0, the variable display of the first special symbol is not executed, and the variable display is started based on the fact that the big hit game is not executed) When time (fluctuation time) elapses, a display result (stop symbol) is derived and displayed. In addition, the variable display of the second special symbol is a variable display start condition (for example, that the game ball has won the second start winning opening 13b) after the second start condition, which is a variable display execution condition, is satisfied (for example, For example, when the number of reserved memories is not 0, the variable display of the second special symbol is not executed, and the big hit game is not executed) is started, When the variable display time (variation time) elapses, the display result (stop symbol) is derived and displayed. Note that winning means that a game ball has entered a predetermined area such as a winning opening. Deriving and displaying the display result is to finally stop and display a symbol (an example of identification information).

  The effect display device 9 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display 8a and during the variable display time of the second special symbol on the second special symbol display 8b. Display design (also referred to as a decorative design) as a design. The variable display of the first special symbol on the first special symbol display 8a and the variable display of the effect symbol on the effect display device 9 are synchronized. Further, the variable display of the second special symbol on the second special symbol display 8b and the variable display of the effect symbol on the effect display device 9 are synchronized. Synchronous means that the start time and end time of variable display are substantially the same (may be exactly the same) and the variable display period is substantially the same (may be exactly the same). Further, when the jackpot symbol is stopped and displayed on the first special symbol display 8a and when the jackpot symbol is stopped and displayed on the second special symbol display 8b, the effect display device 9 reminds the jackpot The combination of is stopped and displayed.

  Below the effect display device 9, a winning device having a first start winning port 13a is provided. The game ball won in the first start winning opening 13a is guided to the back of the game board 6, and is detected by the first start opening switch 14a (for example, proximity switch) and the first winning confirmation switch 14b (for example, photo sensor). The

  Further, on the right side of the winning device having the first starting winning opening (first starting port) 13a, there is a variable winning ball device 15 (see, for example, FIG. 28) having the second starting winning port 13b through which a game ball can be won. Is provided. The game ball that has won the second start winning opening (second start opening) 13b is guided to the back of the game board 6 and detected by the second start opening switch 15a and the winning confirmation switch 15b. The variable winning ball device 15 is opened by a solenoid 16. When the variable winning ball apparatus 15 is in the open state, the game ball can be won in the second start winning opening 13b (it is easy to start winning), which is advantageous for the player. In a state where the variable winning ball device 15 is in the open state, it is easier for the game ball to win the second starting winning port 13b than the first starting winning port 13a. In addition, in a state where the variable winning ball device 15 is in the closed state, the game ball does not win the second start winning opening 13b. In the state where the variable winning ball device 15 is in the closed state, it may be configured that the winning is possible (that is, it is difficult for the gaming ball to win) although it is difficult to win a prize.

  In addition, it is determined whether or not an abnormal winning has occurred based on the detection results of the first starting port switch 14a and the first winning confirmation switch 14b and the detection results of the second starting port switch 15a and the second winning confirmation switch 15b.

The first start winning opening 13a is provided directly below the effect display device 9, but the interval between the lower end of the effect display device 9 and the first start winning port 13a is further reduced, or the first start winning port is set. The winning rate of the second starting winning port 13b is such that the nails are densely arranged around 13a, or the nail arrangement around the first starting winning port 13a is difficult to guide the game ball to the first starting winning port 13a. You may make it make higher than the winning rate of the 1st start winning opening 13a.

  In the upper part of the second special symbol display 8b, the number of effective winning balls that have entered the first start winning opening 13a, that is, the first reserved memory number (the reserved memory is also referred to as the start memory or the start prize memory) is displayed. A first special symbol reserved memory display section and the first special symbol reserved memory display section are provided separately, and a second special special display for displaying the number of effective winning balls that have entered the second start winning slot 13b, that is, the second reserved memory number. For example, a special symbol storage memory display unit 18 including a 7-segment LED provided with a symbol storage memory display unit is provided. The first special symbol reserved memory display unit displays up to four first reserved memory numbers in the order of winning, and increases the number of indicators that are turned on by 1 each time there is an effective start winning. Then, each time the variable display on the first special symbol display 8a is started, the number of indicators to be turned on is reduced by one. The second special symbol reserved memory display unit displays up to four second reserved memory numbers in the order of winning, and increases the number of indicators that are turned on by 1 each time there is an effective start winning. Then, each time the variable display on the second special symbol display 8b is started, the number of indicators to be turned on is reduced by one. In this example, the upper limit number (up to 4) is provided for the start memory number by winning to the first start winning port 13a and the start memory number by winning to the second start winning port 13b. May be four or more.

  Further, the display screen of the effect display device 9 is provided with a first reserved memory display unit 9a for displaying the first reserved memory number and a second reserved memory display unit 9b for displaying the second reserved memory number. . In addition, you may make it provide the area | region (sum total pending | holding memory display part) which displays the total number (sum total pending memory count) which is the sum total of the 1st pending memory count and the 2nd pending memory count. As described above, if the summation pending storage display section for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that are not satisfied with the variable display start condition.

  In this embodiment, as shown in FIG. 1, there is provided a variable winning ball device 15 that opens and closes only the second starting winning opening 13b. However, the first starting winning opening 13a and the second starting winning opening 13b are provided. A configuration in which a variable winning ball apparatus that performs an opening / closing operation may be provided for any of the winning openings 13b.

The first special variable winning ball apparatus 20A includes a large winning opening door 20b (see FIGS. 26 and 27) disposed substantially horizontally in the left-right direction, and a specific display result ( In the specific game state (big hit game state) that occurs when the big win symbol) is derived and displayed, and when the specific display result (big hit symbol) is derived and displayed on the second special symbol display 8b, the big prize is won by the solenoid 21A. When the door 20b is controlled to be in the open state, the first grand prize winning port 20a (see FIGS. 26 and 27) serving as the winning area is opened.

  In the first grand prize opening 20a, switches (a first count switch 23a and a third prize confirmation switch 24a) capable of detecting a game ball won in the first big prize opening 20a are provided at two locations. Therefore, in this embodiment, the game ball won in the first grand prize opening 20a is guided to the back of the game board 6, first detected by the first count switch 23a, and then detected by the third winning confirmation switch 24a. The

  Based on the detection of game balls by the first count switch 23a, a predetermined number (for example, 15) of game balls are paid out as prize balls. Thus, when the game ball passes (enters) the first special winning opening 20a that has been opened in the first special variable winning ball apparatus 20A, for example, the first starting winning opening 13a, the second starting winning opening 13b, etc. More prize balls are paid out than when a game ball passes (enters) through the prize opening. Therefore, if the first special winning opening 20a is in the open state in the first special variable winning ball apparatus 20A, the first state is advantageous to the player. On the other hand, if the first special winning opening 20a is closed in the first special variable winning ball apparatus 20A, the game ball cannot pass through (enter) the first large winning opening 20a, and a prize ball cannot be obtained. The second state is disadvantageous for the player.

  Further, as shown in FIG. 1, a second special variable winning ball device 20B is provided at a lower position of the winning device having the first starting winning port (first starting port) 13a. The second special variable winning ball apparatus 20B includes a movable piece 20d (see FIG. 12) provided so as to be rotatable about a rotation axis that is erected with respect to the board surface of the game board 6 and faces in the front-rear direction. A specific gaming state that occurs when a specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a and when a specific display result (big hit symbol) is derived and displayed on the second special symbol display 8b In the big hit game state), the movable piece 20d is controlled to be opened by the solenoid 21B, so that the second big prize opening 20c (see FIG. 12), which is a winning area, is opened.

  In the second grand prize opening 20c, switches (second count switch 23b and fourth prize confirmation switch 24b) capable of detecting the game balls won in the second big prize opening 20c are provided in two places. Therefore, in this embodiment, the game ball won in the second grand prize opening 20c is guided to the back of the game board 6, first detected by the second count switch 23b, and then detected by the fourth winning confirmation switch 24b. The

  Based on the detection of the game ball by the second count switch 23b, a predetermined number (for example, 15) of game balls are paid out as prize balls. Thus, when the game ball passes (enters) through the second large winning opening 20c that has been opened in the second special variable winning ball apparatus 20B, for example, the first starting winning opening 13a, the second starting winning opening 13b, etc. More prize balls are paid out than when a game ball passes (enters) through the prize opening. Therefore, when the second special prize winning device 20B is in the open state in the second special variable winning ball apparatus 20B, the first state advantageous to the player is obtained. On the other hand, in the second special variable winning ball apparatus 20B, if the second big prize opening 20c is in a closed state, the game ball cannot pass through (enter) the second big prize opening 20c to obtain a prize ball. The second state is disadvantageous for the player.

  The normal symbol display 10 is provided on the right side of the first special symbol display 8a. The normal symbol display 10 is composed of, for example, two lamps. When the game ball passes through the gate 32 and is detected by the gate switch 32a, variable display of the normal symbol display 10 is started. In this embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. When the lamp on the lower side of the normal symbol display 10 is turned on and it is a win, the variable winning ball device 15 is opened for a predetermined number of times. That is, the state of the variable winning ball device 15 is a state that is advantageous from a disadvantageous state for the player when the lower lamp is lit (a state in which a game ball can win the second start winning opening 13b). ). An upper part of the special symbol storage memory display 18 is provided with a normal symbol storage memory display 41 having four display portions (for example, four segments among seven segment LEDs) for displaying the number of winning balls that have passed through the gate 32. It has been. Each time there is a game ball passing through the gate 32, that is, every time a game ball is detected by the gate switch 32a, the normal symbol storage memory display 41 increases the number of display units to be turned on by one. Then, each time the variable display of the normal symbol display 10 is started, the number of display units that are lit is reduced by one.

  In addition, the normal symbol storage memory display 41 composed of 7 segment LEDs has four display units (segments) for displaying the number of winning balls that have passed through the gate 32, and, for example, the first special variable winning ball device 20A, There are provided two display parts (segments) indicating the number of times the second special variable winning ball apparatus 20B is opened (number of big hit rounds) and two display parts (segments) indicating the gaming state. You may comprise by the indicator different from a symbol reservation memory | storage display part. Further, the normal symbol display 10 may be configured by a segment LED or the like that can variably display a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  The winning holes 29a to 29d of the normal winning device are provided around the second special variable winning ball device 20B, and the game balls that have won the winning ports 29a to 29c are detected by the winning port switch 30a, and the right winning port 29d is detected. The winning game ball is detected by the winning opening switch 30b. Each of the winning holes 29a to 29d constitutes a winning area provided in the game board 6 as an area for accepting game balls and allowing winning. The first start winning opening 13a, the second starting winning opening 13b, the first big winning opening 20a, and the second big winning opening 20c also constitute a winning area that accepts game balls and allows winning.

  On the left side of the game area 7, there is provided a decoration member 25 having a decoration LED 25a that blinks and displays during the game, and there is an out port 26 for absorbing a game ball that has not won a prize. In addition, four speakers 27 that emit sound effects are provided on the left, right, top, and bottom of the outside of the game area 7. On the outer periphery of the game area 7, a top frame lamp 28a, a left frame lamp 28b, and a right frame lamp 28c are provided. The top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, and the decoration LED 25a are examples of a decoration light emitter provided in the gaming machine.

  Although not shown in FIG. 1 and FIG. 2, a prize ball lamp that is turned on during the prize ball payout is provided in the vicinity of the left frame lamp 28b, and the supply ball is cut in the vicinity of the top frame lamp 28a. A ball-out lamp that is sometimes lit is provided. Note that the award ball lamp and the out-of-ball lamp are controlled to be turned on by an effect control microcomputer mounted on the effect control board when the award ball is being paid out or when a ball out is detected. Further, although not shown in particular, a prepaid card unit (hereinafter referred to as “card unit”) 50 that enables lending a ball by inserting a prepaid card is installed adjacent to the pachinko gaming machine 1. .

  A game ball launched from a ball striking device (not shown) by the player's operation enters the game area 7 and then descends the game area 7. The game area 7 is divided into a left area 7a on the left side and a right area 7b on the right side of the effect display device 9 disposed substantially at the center, and the game ball fired in the first operation mode is the left area 7a. For example, the game ball launched in the second operation mode in which the amount of rotation of the operation knob 5 is larger than that in the first operation mode flows down the right region 7b.

  In the present embodiment, the game ball launched into the left area 7a can win the first start prize opening 13a, the first major prize opening 20a, and the prize openings 29a to 29c, and the game ball launched into the right area 7b. The obstacles such as obstacle nails and windmills (not shown) are arranged so that the second start winning opening 13b, the second large winning opening 20c, and the winning opening 29d can be awarded.

  When the game ball enters the first start winning port 13a and is detected by the first start port switch 14a, if the variable display of the first special symbol can be started (for example, the variable display of the special symbol ends, 1), the first special symbol display 8a starts variable display (variation) of the first special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. In other words, the variable display of the first special symbol and the effect symbol corresponds to winning in the first start winning opening 13a. If the variable display of the first special symbol cannot be started, the first reserved memory number is increased by 1 on the condition that the first reserved memory number has not reached the upper limit value.

  When the game ball enters the second start winning port 13b and is detected by the second start port switch 15a, if the variable display of the second special symbol can be started (for example, the special symbol variable display ends, 2), the second special symbol display 8b starts variable display (variation) of the second special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the second special symbol and the effect symbol corresponds to winning in the second start winning opening 13b. If the variable display of the second special symbol cannot be started, the second reserved memory number is increased by 1 on condition that the second reserved memory number has not reached the upper limit value.

  The variable display of the first special symbol on the first special symbol display 8a and the variable display of the second special symbol on the second special symbol display 8b are stopped when a certain time has elapsed. If the special symbol at stop (stop symbol) is a big hit symbol (specific display result), it will be “big hit”. If the special symbol at stop (stop symbol) is displayed differently from the big hit symbol, "

  After the variable display result in the special figure game becomes “big hit”, the game is controlled to the big hit gaming state as a specific gaming state in which a round advantageous to the player (also referred to as “round game”) is executed a predetermined number of times.

  In this embodiment, when the big special symbol corresponding to “non-probable big hit C (also referred to as normal big hit C)” and “probable big hit A” is stopped and displayed in the special figure game, the multi-round specific game The state shifts to the first big hit state (12 round big hit state). In the first big hit game state, the big prize opening door 20b of the first special variable winning ball apparatus 20A generates a predetermined period (for example, 29.5 seconds) or a predetermined number (for example, eight) of winning balls. By making the first big prize opening 20a in the open state during the period until this time, a round in which the first special variable winning ball apparatus 20A is changed to the first state (open state) advantageous to the player is executed. In this way, the grand prize opening door 20b that opened the first grand prize opening 20a during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the first big prize opening 20a. Thus, the first special variable winning ball apparatus 20A is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the 12 round big hit state, the number of executions of the round which is the opening cycle of the first big winning opening 20a becomes the first round number (for example, “12”). A game in a 12-round big hit state in which the number of round executions is “12” is also referred to as a 15-time open game. In such a 12 round big hit state, every time a game ball wins the first big winning opening 20a, 15 balls (prize balls) are obtained. The 12-round big hit state is also referred to as a first specific gaming state.

  When the big hit symbol corresponding to “probability big hit B” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the second big hit state (high speed 12 round big hit state) as the multi-round specific gaming state. In the second big hit state, the movable piece 20d of the second special variable winning ball apparatus 20B has a second period (for example, about 0.15 seconds) shorter than the first period in the first big hit state or a predetermined number (for example, three pieces). ), The first special variable winning ball apparatus 20A is changed to a first state (open state) advantageous to the player by opening the second large winning opening 20c in the period until the winning ball is generated. A round is executed. In this way, the movable piece 20d that opened the second grand prize opening 20c during execution of the round receives the game ball falling on the surface of the game board 6, and then closes the second big prize opening 20c. Then, the second special variable winning ball apparatus 20B is changed to the second state (closed state) which is disadvantageous for the player, and one round is completed.

  In such a second big hit state, 15 game balls (prize balls) are obtained if a game ball wins the second big winning opening 20c, but the opening period of the second big winning opening 20b is the second period ( About 0.15 seconds) and very short. For this reason, the second big hit state is a big hit gaming state in which it is practically impossible to obtain a ball (prize ball). The second big hit state is also called a second specific game state. Further, the second big hit state may be one in which the number of executions of the same round as the first big hit state is small. That is, the second big hit state is a second period in which the period (open condition) for changing the second big prize opening 20c to the open state in each round is shorter than the first period in the first big win state.

  In addition, after the first big hit state is ended based on the fact that the big hit symbol corresponding to “non-probable variable big hit C” is stopped and displayed as a confirmed special symbol in the special figure game, it is changed to the normal state as one of the special gaming states. In comparison, the time-shortening control (time-shortening control) in which the variable symbol variable display time (special-figure fluctuation time) in the special-figure game is shortened is controlled to be in a short time state. Here, the normal state is a normal game state as a game state different from a specific game state such as a big hit game state, a probability change state, and a short time state, and an initial setting state of the pachinko gaming machine 1 (for example, a system reset is performed). As in the case where the initialization process is performed after the power is turned on, the same control is performed. If the time-saving state ends when either of the predetermined number of times (e.g., 70 times) of the special figure game is executed and the variable display result is “big hit” is satisfied first, Good. In this way, the big hit that is controlled to the short-time state after the first big hit state is ended based on the fact that it is stopped and displayed as the confirmed special symbol in the special figure game, such as the special bonus symbol corresponding to the “non-probable big hit C” The symbol is referred to as a non-probable big hit symbol (also referred to as “normal big hit symbol”). Further, the fact that the non-probable variable big hit symbol among the big hit symbols is stopped and displayed and the variable display result becomes “big hit” is called “non-probable big hit” (also referred to as “normal big hit”).

  After the first big hit state or the second big hit state is ended based on the fact that the big hit symbol corresponding to “probable big hit A” and “probable big hit B” is stopped and displayed as a confirmed special symbol in the special figure game, As one of the different special gaming states, for example, it is controlled to a probability variation state (high probability state) in which probability variation control (probability variation control) is continuously performed together with time-shortening control in which the special figure variation time is shortened compared to the normal state. The In this probabilistic state, the variable display result of each special figure game and decorative design is improved so that the probability that the variable display result will be “big hit” and further controlled to the big hit gaming state will be higher than in the normal state and the short-time state. To do. Such a probability change state continues until the next variable display result is a “big hit”, regardless of the number of executions of the special game.

  Like the jackpot symbols corresponding to these “probable bonus jackpot A” and “probable bonus jackpot B”, the jackpot symbol that is controlled to the odd-change state after the jackpot state based on being stopped and displayed as a confirmed special symbol in the special figure game is This is called the probable big hit symbol. In addition, like the big hit symbol corresponding to “probable big hit B”, the big hit symbol controlled to the probable change state after the second big hit state based on being stopped and displayed as the confirmed special symbol in the special figure game is It is called a jackpot symbol. In addition, the probability variation big hit symbol out of the big hit symbol is stopped and displayed and the variable display result becomes “big hit” is called “probable big hit”. The fact that the sudden hit symbol is stopped and displayed and the variable display result is “big hit” is called “surprise big hit” (also referred to as “surprise big hit”). These jackpot symbols are arbitrary. For example, in order to prevent the player from recognizing the jackpot type, the jackpot symbol may not be a number but may be a predetermined symbol or the like. .

  In the probabilistic state and the short time state, the normal symbol display unit 10 controls the normal symbol in the normal symbol game so that the variation time of the normal symbol (ordinary symbol variation time) is shorter than that in the normal state. Control to improve the probability that the display result is “per normal” than in the normal state, and open control of the movable plate in the variable winning ball apparatus 15 based on the fact that the variable display result is “per normal” The second start by making it easier for the game ball to pass (enter) the second start winning opening 13b, such as a control for making the release control time longer than that in the normal state and a control for increasing the number of times of opening compared to the normal state. Control that is advantageous to the player is performed by increasing the possibility that the condition is satisfied. It should be noted that any one of these controls may be performed in the probability change state or the short time state, or a plurality of controls may be performed in combination. As described above, the control that facilitates the entry of the game ball into the second start winning opening 13b in the probability change state or the short time state is also referred to as high release control. By performing the high opening control, the frequency at which the second start winning opening 13b is in the open state is higher than when the high opening control is not performed. As a result, the second start condition for executing the special figure game using the second special figure in the second special symbol display 8b is easily established, and the special figure game can be executed frequently. In addition, the time until the variable display result becomes “big hit” is shortened. Therefore, in the probability variation state and the short time state, it becomes easier to enter the big hit gaming state than in the normal state. The period during which the high opening control can be executed is also referred to as a high opening control period, and this period may be the same as the period during which the gaming state in the pachinko gaming machine 1 is controlled to either the certain change state or the short-time state. . Further, it is also said that the gaming state is in the high base during the high opening control period. On the other hand, when it is not the high opening control period, it is said that the gaming state is in the low base. The short-time state in this embodiment is a gaming state also referred to as a low-probability high-base state, and the normal state is a gaming state also referred to as a low-probability low-base state, which is a probabilistic state that is not a high release control period. The latent probability changing state is a gaming state also called a high probability low base state.

  In addition, the probability variation state includes not only the time variation control and the high release control are performed together with the probability variation control but also the one in which only the probability variation control is performed and the time reduction control and the high release control are not performed (latency probability variation). It may be. In addition, for example, after the end of the first big hit state based on the fact that the variable display result in the special figure game is “probable big hit A”, the first positive change state (high high speed control in which time-shortening control and high opening control are performed together with the positive change control) When the number of executions of the special figure game reaches a predetermined number of times (for example, 70 times) without the special figure display result being “big hit”, the probability variation control is continued. However, the control may be performed in a second certain change state (also referred to as a highly accurate low base state) that is not performed after the time-shortening control or the high opening control is finished.

  After the first big hit state based on the “probable big hit A”, the second big hit state based on the “surprise big hit” is controlled while the special figure display result again becomes the “big hit”. After the completion of, the transition to the first certain change state is made, and the special figure display result does not become “big hit” and the special figure game is executed when the number of executions reaches a predetermined number. May be. While the short-time control and the high-open control are started and ended simultaneously (interlocked), the start and end of the probability variation control is not necessarily linked to the start and end of the short-time control and high-open control. May be.

  In the “left”, “middle”, and “right” decorative symbol display areas provided in the effect display device 9, the special symbol game using the first special symbol and the second special symbol in the first special symbol display 8a. Corresponding to the start of one of the special figure games using the second special figure on the display unit 8b, the variable display (variation display) of the decorative symbols is started. In the period from the start of variable display of decorative symbols to the end of variable display due to the stop display of the fixed decorative symbols in the “left”, “middle”, and “right” decorative symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state refers to a decorative pattern (“reach” which has not been temporarily stopped yet when the decorative pattern temporarily stopped displayed in the display area of the effect display device 9 forms a part of the jackpot combination. "Varying symbols") is a display state in which the variation continues, or a display state in which all or part of the decorative symbols change synchronously while constituting all or part of the jackpot combination. is there. Specifically, a part of the “left”, “middle”, and “right” decorative symbol display areas (for example, “left” and “right” decorative symbol display areas) constitutes a predetermined jackpot combination. In a remaining decorative symbol display area (for example, a “medium” decorative symbol display area, etc.) that has not yet been temporarily stopped when a decorative symbol (for example, a decorative symbol indicating the alphanumeric character “7”) is temporarily stopped. The display state in which the decorative symbols are changing, or all or part of the “left”, “middle”, and “right” decorative symbol display areas are synchronized while the decorative symbols constitute all or part of the jackpot combination. The display state is changing.

  FIG. 3 is a block diagram showing an example of the circuit configuration of the main board (game control board) 31. FIG. 3 also shows a payout control board 37, an effect control board 80, and the like. A game control microcomputer (corresponding to game control means) 156 for controlling the pachinko gaming machine 1 according to a program is mounted on the main board 31. The game control microcomputer 156 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means used as a work memory, a CPU 56 for performing control operations in accordance with the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and the RAM 55 are built in the game control microcomputer 156. That is, the game control microcomputer 156 is a one-chip microcomputer. The one-chip microcomputer only needs to include at least the RAM 55, and the ROM 54 may be external or internal. The I / O port unit 57 may be externally attached. The game control microcomputer 156 further includes a random number circuit 60 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 156, the CPU 56 executes control in accordance with the program stored in the ROM 54, so that the game control microcomputer 156 (or CPU 56) executes (or performs processing) hereinafter. Specifically, the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31.

  The game control microcomputer 156 includes a random number circuit 60. The random number circuit 60 is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 60 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 60 is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 60 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 60 is configured to select a numeric data update range selection setting function (initial value selection setting function and upper limit selection selection function), numeric data update rule selection setting function, and numeric data update rule selection. It has various functions such as a switching function. With such a function, the randomness of the generated random numbers can be improved.

  Further, the game control microcomputer 156 has a function of setting an initial value of numerical data updated by the random number circuit 60. For example, a predetermined calculation is performed using an ID number of the game control microcomputer 156 stored in a predetermined storage area such as the ROM 54 (an ID number assigned with a different value for each product of the game control microcomputer 156). The numerical data obtained by the setting is set as the initial value of the numerical data updated by the random number circuit 60. By performing such processing, the randomness of the random number generated by the random number circuit 60 can be further improved.

  The game control microcomputer 156 reads the numerical data as random R from the random number circuit 60 when the start winning to the first start port switch 14a or the second start port switch 15a occurs, and starts to change the special symbol and the effect symbol Sometimes it is determined whether or not to make a big hit display result as a specific display result based on the random R, that is, whether or not to make a big hit. Then, when it is determined to be a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player.

  Further, the game control microcomputer 156 is used for inputting / outputting (transmitting / receiving) signals to / from the payout control board 37 (the payout control microcomputer) and the effect control board 80 (the effect control microcomputer) by serial communication. A serial communication circuit 61 is incorporated. The payout control microcomputer and the effect control microcomputer also have a serial communication circuit (not shown) for inputting / outputting signals with the game control microcomputer 156 through serial communication.

  The RAM 55 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power supply created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data corresponding to the game state, that is, the control state of the game control means (such as the value of the special symbol process flag and the pending storage number counter) and data indicating the number of unpaid prize balls (specifically, prize balls described later) The value of the command output counter) is stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid prize balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal from the power supply board is input to the reset terminal of the game control microcomputer 156. A reset circuit for generating a reset signal supplied to the game control microcomputer 156 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 156 and the like become operable, and when the reset signal becomes low level, the game control microcomputer 156 and the like become inoperative. Therefore, an allowable signal that allows the operation of the game control microcomputer 156 or the like is output during a period in which the reset signal is at a high level, and a game control microcomputer in which the reset signal is at a low level. An operation stop signal for stopping the operation of 156 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Further, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 156. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). Instead of mounting the power monitoring circuit on the power supply board, it may be mounted on a board that is backed up by a backup power supply (for example, the main board 31). Further, a clear signal indicating that the clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 156.

  In addition, the gate switch 32a, the first start opening switch 14a, the first winning confirmation switch 14b, the second starting opening switch 15a, the second winning confirmation switch 15b, the first count switch 23a, the second count switch 23b, and the third winning confirmation An input driver circuit 58 that supplies detection signals from the switch 24a, the fourth winning confirmation switch 24b, and the winning opening switches 30a, 30b to the basic circuit is also mounted on the main board 31, and the solenoid 16 for opening and closing the variable winning ball device 15, A solenoid 21A that opens and closes the first special variable winning ball apparatus 20A, a solenoid 21B that opens and closes the second special variable winning ball apparatus 20B, and an output circuit 59 that is driven in accordance with a command from the basic circuit are also mounted on the main board 31. System reset for resetting the game control microcomputer 156 An information output circuit 64 that outputs an information output signal such as a jackpot information indicating the occurrence of a jackpot gaming state or a jackpot information to the external device such as a hall computer via the terminal board 91 is also the main board. 31.

  In this embodiment, the effect control means (configured by the effect control microcomputer) mounted on the effect control board 80 instructs the effect contents from the game control microcomputer 156 via the relay board 77. The control command is received, and display control with the effect display device 9 that variably displays the effect symbol is performed.

  The effect control board 80 is equipped with an effect control microcomputer (not shown) including an effect control CPU and a RAM. The RAM may be externally attached. In the effect control board 80, an effect control CPU (not shown) operates according to a program stored in a built-in or external ROM (not shown), and receives from the main board 31 inputted via the relay board 77. An effect control command is received via the input driver and the input port in response to the embedded signal (effect control INT signal). Further, the effect control CPU (not shown) causes the VDP (video display processor) to perform display control of the effect display device 9 based on the effect control command.

  An effect control CPU (not shown) reads necessary data from a character ROM (not shown) in accordance with the received effect control command. The character ROM is for storing character image data displayed on the effect display device 9, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. An effect control CPU (not shown) outputs the data read from the character ROM to the VDP. The VDP performs display control based on data input from the CPU for effect control.

  The effect control command and the effect control INT signal are first input to the input driver on the effect control board 80. The input driver allows the signal input from the relay board 77 to pass only in the direction toward the inside of the effect control board 80 (does not pass the signal in the direction from the inside of the effect control board 80 to the relay board 77). It is also a unidirectional circuit as a means.

  As a signal direction regulating means, the signal inputted from the main board 31 is allowed to pass through the relay board 77 only in the direction toward the effect control board 80 (the signal is not passed in the direction from the effect control board 80 to the relay board 77). A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. Furthermore, since the production control command and the production control INT signal are output from the main board 31 via the I / O port unit which is a unidirectional circuit, the signal going from the relay board 77 to the inside of the main board 31 is restricted. . That is, the signal from the relay board 77 does not enter the inside of the main board 31 (the game control microcomputer 156 side).

  Further, the effect control CPU (not shown) outputs a signal for driving the LED to the lamp driver board 35 via an output port (not shown). The effect control CPU outputs sound number data to the sound control board 70 via the output port. In addition, the effect control CPU outputs a drive signal to the decorative board solenoid 341 via the output port.

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver supplies a drive signal to each LED provided on the frame side such as the top frame LED 28a, the left frame LED 28b, and the right frame LED 28c. Further, a drive signal is supplied to the decoration LED 25a provided on the game board side. When a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 35.

  In the voice control board 70, the sound number data is input to a voice synthesis IC (not shown) via an input driver (not shown). The voice synthesizing IC generates voice and sound effects corresponding to the sound number data and outputs them to an amplifier circuit (not shown). The amplifier circuit outputs to the speaker 27 an audio signal obtained by amplifying the output level of the voice synthesis IC to a level corresponding to the volume set by the volume. Control data corresponding to sound number data is stored in a sound data ROM (not shown). The control data corresponding to the sound number data is a collection of data showing the output form of the sound effect or sound in a time series in a predetermined period (for example, the changing period of the effect design).

  Next, the operation of the gaming machine will be described. FIG. 4 is a flowchart showing main processing executed by the game control microcomputer 156 on the main board 31. When power is supplied to the gaming machine and power supply is started, the input level of the reset terminal to which the reset signal is input becomes high level, and the gaming control microcomputer 156 (specifically, the CPU 56) After executing a security check process, which is a process for confirming whether the contents of the program are valid, the main process after step S1 is started. In the main process, the CPU 56 first performs necessary initial settings.

  In the initial setting process, the CPU 56 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S2), and a stack pointer designation address is set to the stack pointer (step S3). After initialization of the built-in device (CTC (counter / timer) and PIO (parallel input / output port), which are built-in devices (built-in peripheral circuits)) is performed (step S4), the RAM is accessible (Step S5). In interrupt mode 2, the address synthesized from the value (1 byte) of the specific register (I register) built in the CPU 56 and the interrupt vector (1 byte: least significant bit 0) output from the built-in device is This mode indicates an interrupt address.

  Next, the CPU 56 checks the state of the output signal (clear signal) of a clear switch (for example, mounted on the power supply board) input via the input port (step S6). When the ON is detected in the confirmation, the CPU 56 executes normal initialization processing (steps S10 to S15).

  If the clear switch is not on, check whether data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) was performed when power supply to the gaming machine was stopped (Step S7). When it is confirmed that such protection processing is not performed, the CPU 56 executes initialization processing. Whether there is backup data in the backup RAM area is confirmed, for example, by the state of the backup flag set in the backup RAM area in the power supply stop process.

  When it is confirmed that the power supply stop process has been performed, the CPU 56 performs data check of the backup RAM area (step S8). In this embodiment, a parity check is performed as a data check. Therefore, in step S8, the calculated checksum is compared with the checksum calculated and stored by the same process in the power supply stop process. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area is different from the data when the power supply is stopped. In such a case, since the internal state cannot be returned to the state when the power supply is stopped, an initialization process that is executed when the power is turned on is not performed when the power supply is stopped.

  If the check result is normal, the CPU 56 recovers the game state restoration process (steps S41 to S43) for returning the internal state of the game control means and the control state of the electrical component control means such as the effect control means to the state when the power supply is stopped. Process). Specifically, the start address of the backup setting table stored in the ROM 54 is set as a pointer (step S41), and the contents of the backup setting table are sequentially set in the work area (area in the RAM 55) (step S42). ). The work area is backed up by a backup power source. In the backup setting table, initialization data for an area that may be initialized in the work area is set. As a result of the processing in steps S41 and S42, the saved contents of the work area that should not be initialized remain as they are. The part that should not be initialized is, for example, data indicating the gaming state before the power supply is stopped (special symbol process flag, probability variation flag, time reduction flag, etc.), and the area where the output state of the output port is saved (output port buffer) ), A portion in which data indicating the number of unpaid prize balls is set.

  Further, the CPU 56 transmits a power failure recovery designation command as an initialization command at the time of power supply recovery (step S43). Then, the process proceeds to step S14. In this embodiment, the CPU 56 also transmits, to the effect control board 80, a total reserved memory number designation command in which the value of the total reserved memory number counter stored in the backup RAM is set in step S43.

  In this embodiment, it is confirmed whether or not the data in the backup RAM area is stored by using both the backup flag and the check data. However, only one of them may be used. That is, either the backup flag or the check data may be used as an opportunity for executing the game state restoration process.

  In the initialization process, the CPU 56 first performs a RAM clear process (step S10). The RAM clear process initializes predetermined data (for example, count value data of a counter for generating a random number for normal symbol determination) to 0, but an arbitrary value or a predetermined value It may be initialized to. In addition, the entire area of the RAM 55 may not be initialized, and predetermined data (for example, count value data of a counter for generating a random number for normal symbol determination) may be left as it is. Further, the start address of the initialization setting table stored in the ROM 54 is set as a pointer (step S11), and the contents of the initialization setting table are sequentially set in the work area (step S12).

  By the processing in steps S11 and S12, for example, a normal symbol per-determining random number counter, a special symbol buffer, a total prize ball number storage buffer, a special symbol process flag, and other flags for selectively performing processing according to the control state are initialized. Value is set.

  In addition, the CPU 56 initializes a sub board (a board on which a microcomputer other than the main board 31 is mounted). An initialization designation command (a command indicating that the game control microcomputer 156 has executed initialization processing). Is also transmitted to the sub-board (step S13). For example, when receiving the initialization designation command, the effect control microcomputer performs display on the effect display device 9 for notifying that the control of the gaming machine has been initialized, that is, initialization notification.

  Further, the CPU 56 executes a random number circuit setting process for initially setting the random number circuit 60 (step S14). For example, the CPU 56 performs setting according to the random number circuit setting program so as to cause the random number circuit 60 to update the random R value.

  In step S15, the CPU 56 sets a CTC register built in the game control microcomputer 156 so that a timer interrupt is periodically generated every predetermined time (for example, 2 ms). That is, a value corresponding to, for example, 2 ms is set in a predetermined register (time constant register) as an initial value. In this embodiment, it is assumed that a timer interrupt is periodically taken every 2 ms.

  When the execution of the initialization process (steps S10 to S15) is completed, the CPU 56 repeatedly executes the display random number update process (step S17) and the initial value random number update process (step S18) in the main process. When executing the display random number update process and the initial value random number update process, the interrupt disabled state is set (step S16). When the display random number update process and the initial value random number update process are finished, the interrupt enabled state is set. Set (step S19). In this embodiment, the display random number is a random number for determining the stop symbol of the special symbol when it is not a big hit, or a random number for determining whether to reach when it is not a big hit, The random number update process is a process for updating the count value of a counter for generating a display random number. The initial value random number update process is a process for updating the count value of the counter for generating the initial value random number. In this embodiment, the initial value random number determines the initial value of the count value of a counter for generating a random number for determining whether or not to win a normal symbol (ordinary random number generation counter for normal symbol determination). It is a random number to do. A game control process for controlling the progress of the game, which will be described later (the game control microcomputer 156 controls itself a game device such as an effect display device, a variable winning ball device, a ball payout device, etc. provided in the gaming machine. In the process of transmitting a command signal to be controlled by another microcomputer, or a game machine control process), the count value of the random number for determination per normal symbol is one round (the random number for determination per normal symbol is taken). When the value is incremented by the number of values between the minimum value and the maximum value of the possible values), an initial value is set in the counter.

  In this embodiment, the reach effect is executed using an effect symbol (decorative symbol) variably displayed on the effect display device 9. Further, when the display result of the special symbol is a jackpot symbol, the reach effect is always executed. When the display result of the special symbol is not a jackpot symbol, the game control microcomputer 156 determines whether or not to execute the reach effect by lottery using a random number. However, it is the production control microcomputer that actually executes the reach production control.

  When the timer interrupt occurs, the CPU 56 executes the timer interrupt process of steps S20 to S34 shown in FIG. In the timer interrupt process, first, a power-off detection process for detecting whether or not a power-off signal is output (whether or not an on-state is turned on) is executed (step S20). The power-off signal is output, for example, when a power supply monitoring circuit mounted on the power supply board detects a decrease in the voltage of the power supplied to the gaming machine. In the power-off detection process, when detecting that the power-off signal has been output, the CPU 56 executes a power supply stop process for saving necessary data in the backup RAM area. Next, detection signals of the gate switch 32a, the first start port switch 13a, the second start port switch 14a, the first count switch 23a, and the second count switch 23b are input via the input driver circuit 58, and their state determination is performed. (Switch processing: step S21).

  Next, the CPU 56 has a first special symbol display 8a, a second special symbol display 8b, a normal symbol display 10, a first special symbol hold storage display 18a, a second special symbol hold storage display 18b, a normal symbol. A display control process for controlling the display of the on-hold storage display 41 is executed (step S22). About the 1st special symbol display 8a, the 2nd special symbol display 8b, and the normal symbol display 10, a drive signal is output with respect to each display according to the content of the output buffer set by step S32, S33. Execute control.

  Also, a process of updating the count value of each counter for generating each random number for determination such as a random number for determination per ordinary symbol used for game control is performed (determination random number update process: step S23). The CPU 56 further performs a process of updating the count value of the counter for generating the initial value random number and the display random number (initial value random number update process, display random number update process: steps S24 and S25).

  Further, the CPU 56 performs special symbol process processing (step S26). In the special symbol process, the first special symbol display 8a, the second special symbol display 8b, the first big prize opening 20a, and the second big prize opening 20c are applicable according to a special symbol process flag for controlling in a predetermined order. Execute the process. The CPU 56 updates the value of the special symbol process flag according to the gaming state.

  Next, normal symbol process processing is performed (step S27). In the normal symbol process, the CPU 56 executes a corresponding process according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The CPU 56 updates the value of the normal symbol process flag according to the gaming state.

  Further, the CPU 56 performs a process of sending an effect control command to the effect control microcomputer (effect control command control process: step S28).

  Further, the CPU 56 performs information output processing for outputting data such as jackpot information, start information, probability variation information supplied to the hall management computer, for example (step S29).

  Further, the CPU 56 executes a prize ball process for setting the number of prize balls based on detection signals of the first start port switch 13a, the second start port switch 14a, the first count switch 23a, and the second count switch 23b ( Step S30). Specifically, the payout control board 37 is activated in response to a winning detection based on any one of the first start port switch 13a, the second start port switch 14a, the first count switch 23a, and the second count switch 23b being turned on. A payout control command (award ball number signal) indicating the number of prize balls is output to a mounted payout control microcomputer. The payout control microcomputer drives the ball payout device 97 in accordance with a payout control command indicating the number of winning balls.

  In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. Is output to the output port (step S31: output process).

  Further, the CPU 56 performs special symbol display control processing for setting special symbol display control data for effect display of the special symbol in the output buffer for setting the special symbol display control data according to the value of the special symbol process flag ( Step S32). For example, if the variation speed is 1 frame / 0.2 seconds until the end flag is set when the start flag set in the special symbol process is set, the CPU 56, for example, every 0.2 seconds passes. Then, the value of the display control data set in the output buffer is incremented by one. Further, the CPU 56 outputs a drive signal in step S22 in accordance with the display control data set in the output buffer, whereby the first special symbol display unit 8a and the second special symbol display unit 8b Variable display of the second special symbol is executed.

  Further, the CPU 56 performs a normal symbol display control process for setting normal symbol display control data for effect display of the normal symbol in an output buffer for setting the normal symbol display control data according to the value of the normal symbol process flag ( Step S33). For example, when the start flag related to the variation of the normal symbol is set, the CPU 56 switches the display state (“◯” and “×”) for the variation rate of the normal symbol every 0.2 seconds until the end flag is set. With such a speed, the value of the display control data set in the output buffer (for example, 1 indicating “◯” and 0 indicating “x”) is switched every 0.2 seconds. Further, the CPU 56 outputs a normal signal on the normal symbol display 10 by outputting a drive signal in step S22 according to the display control data set in the output buffer.

  Thereafter, the interrupt permission state is set (step S34), and the process is terminated.

  With the above control, in this embodiment, the game control process is started every 2 ms. The game control process corresponds to the process of steps S21 to S33 (excluding step S29) in the timer interrupt process. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed in the main process. It may be executed.

  6 and 7 are flowcharts showing an example of a special symbol process (step S26) program executed by the game control microcomputer 156 (specifically, the CPU 56) mounted on the main board 31. FIG. As described above, in the special symbol process, a process for controlling the first special symbol display 8a or the second special symbol display 8b, the first big prize opening 20a or the second big prize opening 20c is executed. In the special symbol process, the CPU 56 turns on the first start winning opening 13 when the first start opening switch 13a for detecting that the game ball has won the first start winning opening 13 is turned on. If a winning has occurred, a first start port switch passage process is executed (steps S311 and S312). If the second start port switch 14a for detecting that the game ball has won the second start winning port 14 is turned on, that is, the start winning to the second start winning port 14 has occurred. Then, the second start port switch passage process is executed (steps S313, S314). Then, any one of steps S300 to S310 is performed. If the first start port switch 13a or the second start port switch 14a is not turned on, any one of steps S300 to S310 is performed according to the internal state.

  The processes in steps S300 to S312 are as follows.

  Special symbol normal processing (step S300): Executed when the value of the special symbol process flag is zero. When the game control microcomputer 156 is in a state where variable display of a special symbol can be started, the game control microcomputer 156 checks the number of numerical data stored in the reserved storage number buffer (total number of reserved storage). The stored number of numerical data stored in the pending storage number buffer can be confirmed by the count value of the total pending storage number counter. If the count value of the total pending storage number counter is not 0, it is determined whether or not the display result of the variable display of the first special symbol or the second special symbol is a big hit. In case of big hit, set big hit flag. Then, the internal state (special symbol process flag) is updated to a value (1 in this example) according to step S301. The jackpot flag is reset when the jackpot game ends.

  Fluctuation pattern setting process (step S301): This process is executed when the value of the special symbol process flag is 1. Also, the variation pattern is determined, and the variation time in the variation pattern (variable display time: the time from the start of variable display until the display result is derived and displayed (stop display)) is defined as the variation display variation time of the special symbol Decide to do. Also, a variable time timer for measuring the special symbol variable time is started. Then, the internal state (special symbol process flag) is updated to a value (2 in this example) corresponding to step S302.

  Display result designation command transmission process (step S302): This process is executed when the value of the special symbol process flag is 2. Control is performed to transmit a display result designation command to the effect control microcomputer. Then, the internal state (special symbol process flag) is updated to a value (3 in this example) corresponding to step S303.

  Special symbol changing process (step S303): This process is executed when the value of the special symbol process flag is 3. When the variation time of the variation pattern selected in the variation pattern setting process elapses (the variation time timer set in step S301 times out, that is, the variation time timer value becomes 0), the internal state (special symbol process flag) is stepped. Update to a value corresponding to S304 (4 in this example).

  Special symbol stop process (step S304): executed when the value of the special symbol process flag is 4. The variable display on the first special symbol display 8a or the second special symbol display 8b is stopped, and the stop symbol is derived and displayed. Also, control is performed to transmit a symbol confirmation designation command to the effect control microcomputer. If the big hit flag is set, the internal state (special symbol process flag) is updated to a value (5 in this example) corresponding to step S305. The effect control microcomputer controls the effect display device 9 to stop the effect symbol when receiving the symbol confirmation designation command transmitted by the game control microcomputer 156.

  Preliminary winning opening opening process (step S305): This is executed when the value of the special symbol process flag is 5. In the pre-opening process for the big prize opening, control is performed to open the first big prize opening 20a or the second big prize opening 20c. In the present embodiment, when the big hit type is the probability variation big hit A and the normal big hit C, the first big winning port 20a is opened, and when the big hit type is the probable big hit B, the second big winning port 20b is opened. Specifically, a counter (for example, a counter that counts the number of game balls that have entered the first grand prize opening 20a or the second big prize opening 20c) and the like are initialized, and the solenoid 21A or the solenoid 21B is driven to The first grand prize opening 20a or the second big prize opening 20c is set to an open state. Also, the execution time of the special prize opening opening process is set by the timer, and the internal state (special symbol process flag) is updated to a value corresponding to step S306 (6 in this example). The pre-opening process for the big winning opening is executed every round, but when the first round is started, the pre-opening process for the big winning opening is also a process for starting the big hit game.

  Large winning opening opening process (step S306): This process is executed when the value of the special symbol process flag is 6. A control for transmitting an effect control command for a round display during the big hit gaming state to the effect control microcomputer, a process for confirming the establishment of the closing condition of the first big prize opening 20a or the second big prize opening 20c, and the like are performed. When the closing condition of the first grand prize winning opening 20a or the second big winning prize opening 20c is satisfied and the winning ball detection waiting time has elapsed, the internal state (special symbol process flag) is a value corresponding to step S307. Update to (7 in this example).

  Post-winner opening process (step S307): This process is executed when the value of the special symbol process flag is 7. A control for transmitting an effect control command for a round display during the big hit gaming state to the effect control microcomputer, a process for confirming the establishment of the closing condition of the first big prize opening 20a or the second big prize opening 20c, and the like are performed. If the closing condition of the first grand prize opening 20a or the second big prize opening 20c is satisfied and there are still remaining rounds, the internal state (special symbol process flag) is a value corresponding to step S305 (this example) Then, update to 5). When all the rounds are finished, the internal state (special symbol process flag) is updated to a value (8 in this example) corresponding to step S308.

  Big hit end process (step S308): This process is executed when the value of the special symbol process flag is 8. Control is performed to cause the microcomputer for effect control to perform display control for notifying the player that the big hit gaming state has ended. In addition, a process for setting a flag indicating a gaming state (for example, a probability change flag or a time reduction flag) is performed. Then, the internal state (special symbol process flag) is updated to a value (0 in this example) corresponding to step S300.

  FIG. 8 is a flowchart showing an example of the process executed in step S305 of FIG. In the pre-opening process for the big winning opening shown in FIG. 8, the CPU 56 first determines whether or not the big hit state start flag is on (step S391). At this time, if the big hit state start flag is ON (step S391; Yes), it is determined whether or not the big hit state start waiting time has elapsed (step S392). And if the big hit state start waiting time has not passed (step S392; No), it waits until the big hit state start waiting time passes by ending the big winning opening opening pre-processing. On the side of the effect control board 80, for example, an effect operation for notifying that the jackpot gaming state is started may be executed in a period until the jackpot state start waiting time elapses.

  When the big hit state start waiting time has elapsed in step S392 (step S392; Yes), the big hit state start flag is cleared and turned off (step S393). In addition, a setting for transmitting a big hit start command to the effect control board 80 is performed (step S394). Then, after setting the round start waiting time (step S395), the pre-opening process for the big prize opening is ended.

  When the big hit state pre-start flag is off in step S391 (step S391; No), it is determined whether or not the round start waiting has elapsed (step S396). At this time, if the round start waiting time has not elapsed (step S396; No), the process waits until the round start waiting time elapses by ending the pre-opening of the special winning opening.

  When the round start waiting time elapses in step S396 (step S396; Yes), the winning number counter is cleared and the winning number count value, which is the stored value, is initialized to “0” (step S397). In addition, a maximum winning opening time (for example, 29500 ms or 1500 ms) is set (step S398). At this time, for example, the solenoid 21A is driven and the first prize winning opening 20a is opened by the prize winning door 20b, or the solenoid 21B is driven and the second prize winning opening 20c is opened by the movable piece 20d. Setting is performed (step S399). Furthermore, a setting for transmitting a round start command to the effect control board 80 is performed (step S400). Then, after updating the value of the special figure process flag to “6” which is a value corresponding to the process for opening the big prize opening (step S401), the process for opening the big prize opening is ended.

  FIG. 9 is a flowchart showing an example of the process executed in step S306 of FIG. In the special winning opening opening process shown in FIG. 9, the CPU 56 first determines whether or not a winning ball detection waiting time is set (step S410), and when the winning ball detection waiting time is not set. (Step S410; No), it is determined whether or not the maximum winning opening maximum opening time has elapsed (Step S411). At this time, if the maximum winning opening maximum opening time has not elapsed (step S411; No), it is determined whether or not the first count switch 23a and the second count switch 23b are on (step S412). If the count switch 23a and the second count switch 23b are on (step S412; Yes), the winning ball count command is updated to add 1 (step S413), and then the winning ball number command is transmitted to the payout control board 37. (Step S414), the process proceeds to Step S415. If the first count switch 23a and the second count switch 23b are not on (step S412; No), the process proceeds to step S415 as it is.

  In step S415, it is determined whether or not the winning number count value has reached a predetermined maximum winning determination value (for example, “9”) (step S415). End the mouth open process.

  When the maximum opening time of the big winning opening has passed in step S411 (step S411; Yes), or when the round end condition is satisfied because the winning number count value has reached a predetermined maximum winning determination value in step S415 For example, the driving of the solenoid 21A is stopped and the first prize winning opening 20a is set to the closed state by the prize winning opening door 20b, or the driving of the solenoid 21B is stopped and the second prize winning opening 10c is set by the movable piece 20c. The setting for the closed state is made (step S416). Subsequently, after setting for transmitting a round end command to the effect control board 80 (step S417), a winning ball detection waiting time is set (step S418), and the process for opening the big prize opening is ended. To do.

  Here, the award ball detection waiting time is the second time that a game ball won immediately before closing the grand prize opening door 20b passes through the first count switch 23a and a game ball won immediately before closing the movable piece 20d. This is the time it takes to pass the count switch 23b, and is the first major winning path from the first major winning opening 20a to the first counting switch 23a, or the second from the second major winning opening 20c to the second counting switch 23b. It is set according to the length of the big prize passage. In other words, the game ball or the movable piece 20d detected by the first count switch 23a is closed after the grand prize opening door 20b is closed based on the fact that the above round end condition is satisfied, and then the second count switch 23b is turned on. The game balls detected in this way are detected as game balls that have won over the round, and are not detected as game balls that won in the next round.

  If the prize ball detection waiting time is set in step S410 (step S410; Yes), it is determined whether or not the prize ball detection waiting time has elapsed (step S420), and the prize ball detection waiting time has elapsed. If not (step S420; No), it is determined whether or not the detection signal from the first count switch 23a or the second count switch 23b is on (step S422), and the first count switch 23a or the second count switch 23b is determined. If the detection signal from the 2-count switch 23b is on (step S422; Yes), a prize ball number command is transmitted to the payout control board 37 (step S423), and the process of opening the big prize opening is completed.

  Further, when the winning ball detection waiting time has elapsed in step S420 (step S420; Yes), the value of the special figure process flag is updated to “7” which is a value corresponding to the post-opening process for the big prize opening. (Step S421), the process for opening the special winning opening is ended.

  FIG. 10 is a flowchart showing an example of processing executed in step S307 of FIG. 7 as processing after the special winning opening is opened. In the post-opening process for the special winning opening shown in FIG. 10, the CPU 56 first updates the special winning opening open count value so that 1 is subtracted (step S431). At this time, it is determined whether or not the updated big opening opening count value is “0” (step S432). If the special winning opening opening count value is other than “0” (step S432; No), the round start waiting time is set (step S433), and the value of the special figure process flag is set to the special winning opening opening pre-processing. After the corresponding value is updated to “5” (step S434), the post-opening process for the big prize opening is terminated. Thus, until it is determined by the process of step S432 that the updated big opening opening count value is “0”, the process of steps S305 to S307 shown in FIG. Thus, it is possible to execute a plurality of round games in which the first special variable winning ball device 20A and the second special variable winning ball device 20B are opened.

  When the big prize opening release count value is “0” in step S432 (step S432; Yes), the time before the big hit end is set (step S435). At this time, the big hit flag is cleared and turned off (step S436). Then, after updating the value of the special figure process flag to “8” which is a value corresponding to the big hit end process (step S437), the post-opening process for the big prize opening is ended.

In addition, a solenoid 21B for driving the movable piece 20d is provided.

  As shown in FIGS. 13 to 15, the winning opening unit 301 has a fitting member 306 fitted into an opening (not shown) formed in the game board 6 from the front side, and a front surface of the fitting member 306 is decorated. The decorative member 307, the large winning opening passage member 308 attached to the back side of the decorative member 307, the winning opening member 309 attached to the front surface of the decorative member 307, and the movable piece 20d are mainly configured.

  The fitting member 306 is formed with an insertion hole 310 at the center through which the big prize opening passage member 308 and the like can be inserted.

  The decorative member 307 has a protruding portion 311 that forms the first start winning opening 13a that opens upward at the front upper portion, and a winning ball passing hole 326 having a substantially square shape is formed at a lower position thereof. ing. An escape hole 312 is formed on the right side of the winning ball passing hole 326 to avoid contact with the tip of the rotating shaft 20e of the movable piece 20d. The rotating shaft 20e is composed of a shaft member having a male screw portion (not shown) formed at the tip thereof, and is inserted into a shaft hole 313 formed on the base end side of the movable piece 20d so as to be placed on the back surface of the winning a prize opening member 309. It is screwed into a formed bearing hole (not shown). Thereby, the movable piece 20d is provided between the decoration member 307 and the winning prize opening member 309 so as to be rotatable about a rotation shaft 20e that faces in the front-rear direction, that is, in a direction substantially orthogonal to the board surface of the game board 6. It has been.

  On the right side of the bearing hole 312 in the decorative member 307, a rotation restricting groove 315 having a substantially arc shape centering on the bearing hole 312 is formed. The rotation restricting groove 315 is formed on the back surface of the movable piece 20d. A restricting shaft 314 that protrudes from the front end side of the shaft hole 313 is inserted from the front side. The rotation restricting groove 315 has a length of about ¼ of the circumference around the bearing hole 312.

  That is, in the movable piece 20d provided so as to be rotatable about the rotation shaft 20e facing in the front-rear direction, the restriction shaft 314 is located at the upper end 315b (closed side restriction portion) of the rotation restriction groove 315, and the second large The closed position (see FIG. 19 (a)) that prevents entry of the game ball into the winning opening 20c and the restriction shaft 314 are located at the lower end 315a (open side restriction portion) of the rotation restriction groove 315, and the second large It can be rotated within a rotation range of about 90 degrees from the open position (see FIG. 19B) that allows the game ball to enter the winning opening 20c. The rotation range is regulated by the groove 315.

  Also, as shown in FIG. 17, the length L2 from the rotation shaft 20e to the tip of the movable piece 20d is formed on the glass door frame 102 as shown in FIG. Is longer than the gap L1 from the player side to the see-through window 102a (L1 <L2). That is, the movable piece 20d can be designed to be longer than the gap L1 by being pivotable about the pivot shaft 20e facing the front-rear direction with respect to the front surface (game board surface) of the game board 6. It is possible to make it easier for the player to recognize that the movable piece 20d is open or closed.

  The special winning opening passage member 308 is a cylindrical member whose front and lower surfaces are open, and a second large winning passage 304 having a substantially L shape in a side view is formed therein, and a front opening is provided with a winning ball passing hole 326. Is attached to the back surface of the decorative member 307 with a plurality of screws 316. In addition, a driving force transmission member 317 having a substantially U-shape in plan view is pivotally supported on the outside of the special prize opening passage member 308 so as to be rotatable around a rotation axis facing in the left-right direction.

  The winning opening member 309 is disposed at a front position of the decorative member 307 with a gap slightly larger than the diameter of the game ball with respect to the front surface of the decorative member 307, and the decorative member 307 covers the winning ball passing hole 326 from the front side. Attached to. A wall portion 309a is formed on the back surface of the winning hole member 309 so as to cover the upper side, the left side, and the lower side of the winning ball passage hole 326. The wall portion 309a causes the right side of the front side of the winning ball passage hole 326. A second grand prize-winning port 20c that is open at the top and a concave second major prize-winning passage 304 are formed.

  The base member 302 has an opening in the first start winning path 303 formed in the upper front portion, and communicates with the first start winning opening 13a. The first start winning path 303 is formed from the upper opening downward so as to bypass the right side so as to avoid the second large winning path 304 located immediately below the first opening winning path 303. A switch 14a and a first winning confirmation switch 14b are provided.

  A through hole 318 that penetrates in the front-rear direction and has a size that can accommodate the big prize opening passage member 308 is formed at a position below the upper opening of the first start winning passage 303. A solenoid 21B is disposed on the left rear surface of the through hole 318. The solenoid 21B is connected to the movable piece 20d via a driving force transmission member 317, and constitutes a driving means for opening and closing the movable piece 20d. In addition, a general winning path 305 is formed on the left front surface of the through hole 318 in a state of opening to the front surface.

  Next, the opening / closing drive mechanism 320 of the movable piece 20d will be described with reference to FIGS.

  The opening / closing drive mechanism 320 connects the solenoid 21B for driving the movable piece 20d, the connecting member 321 attached to the tip of the plunger 21b protruding downward from the main body of the solenoid 21B, and the connecting member 321 and the movable piece 20d. The driving force transmission member 317 is mainly composed of.

  Specifically, the solenoid 21B is fixed to the base member 302 with the plunger 21b protruding downward, and a coil spring 21c is provided between the main body and the connecting member 321 on the outer periphery of the plunger 21b. In the non-excited state of the solenoid 21B, the plunger 21b is biased in the extending direction. In the excited state of the solenoid 21B, the plunger 21b is contracted to the main body side against the urging force of the coil spring 21c.

  On the right side of the connecting member 321, a concave portion 322 having an opening on the front surface and the right side surface is formed, and a connecting shaft 323 protruding from the left side surface of the driving force transmitting member 317 is inserted into the concave portion 322. Yes.

  The driving force transmission member 317 is formed in a bifurcated shape in plan view by a pair of left and right arm portions 317a and 317b facing in the front-rear direction and a connecting portion 317c that connects the rear ends of these arm portions 317a and 317b. Concentric rotating shafts 324 and 324 protrude from the inner side surfaces of the pair of left and right arm portions 317a and 317b in the front-rear direction at substantially the center position, and are formed in the bearing holes formed on the left and right side surfaces of the big prize opening passage member 308. (Not shown). Therefore, the driving force transmission member 317 is pivotally supported so as to be swingable in the vertical direction with respect to the special prize opening passage member 308 around the rotation shafts 324 and 324 facing in the left-right direction.

  A connecting shaft 323 protrudes slightly behind the rotation shaft 324 on the outer surface of the left arm portion 317a, and is inserted into the recess 322 of the connecting member 321 so as to be movable back and forth. Further, a right-side inverted C-shaped catch portion 325 is formed at the tip of the right arm portion 317b, and the rear end of the rotation restricting shaft 314 of the movable piece 20d is engaged with the catch portion 325. Yes.

  In addition, the clearance between the tips of the upper and lower catch pieces constituting the catch portion 325 is slightly wider than the diameter of the rotation restricting shaft 314 and is designed to have play. The vertical width of the recess 322 is slightly wider than the diameter of the connecting shaft 323, and is designed to have play.

  Thus, for example, as shown in FIG. 19B, when the movable piece 20d reaches the open position and the rotation restricting shaft 314 comes into contact with the lower end 315a of the turn restricting groove 315, the impact at the time of contact is reached. After rebounding to the closed position side, a rebounding operation is performed to return to the open position again. Further, at this time, a rebound operation is performed in which the rebounding shaft returns to the open position again after rebounding again to the closed position due to an impact when the rotation restricting shaft 314 comes into contact with the lower end 315a of the rotation restricting groove 315. That is, fluttering occurs by repeating the reciprocating motion between the position indicated by the one-dot chain line and the position indicated by the solid line in FIG. Such a rebounding operation is also performed in the closed position. In the open position, the movable piece 20d tilts and a larger moment acts than in the closed position, so that the fluttering is larger than that in the closed position.

  Here, the operation state of the opening / closing drive mechanism 320 when the movable piece 20d is opened / closed will be described mainly with reference to FIGS. First, the movable piece 20d rotates between a closed position that stands up in the up-down direction and an open position that rotates rightward from the open position and tilts while the tip is slightly upward.

  Specifically, when the solenoid 21B is in a non-excited state, the plunger 21b is extended by the urging force of the coil spring 21c. In this state, the connecting member 321 is at the lower limit position, and the connecting shaft 323 is disposed at a substantially horizontal position behind the rotating shaft 324. And since the catch part 325 faces a little upwards, it pushes up the rotation control shaft 314 upward. As a result, the movable piece 20d is maintained in the closed position (see FIGS. 18A and 19A).

  On the other hand, when the solenoid 21B is in an excited state, the plunger 21b is pulled to the main body side against the biasing force of the coil spring 21c and is in a contracted state. In this state, the connecting member 321 is at the upper limit position, and the connecting shaft 323 is pushed up to an upper position above the rotating shaft 324. Since the catch portion 325 faces slightly downward, the rotation restricting shaft 314 is pushed downward. Thereby, the movable piece 20d is maintained in the open position (see FIGS. 18B and 19B).

  As described above, the plunger 21b is vertically expanded and contracted by the solenoid 21B, so that the front and rear of the driving force transmission member 317 provided so as to be rotatable about the rotation shaft 324 directed in the left-right direction swings in the vertical direction. When the catch portion 325 moves the rotation restricting shaft 314 up and down in the rotation restricting groove 315, the movable piece 20d provided so as to be rotatable around the turning shaft 20e facing in the front-rear direction is defined as a closed position. It is rotated within a rotation range of about 90 degrees with respect to the open position.

  Further, the movable piece 20d is restricted from rotating toward the open position (clockwise when viewed from the front) by the rotation restricting shaft 314 coming into contact with the lower end 315a of the inner peripheral edge of the turn restricting groove 315 at the open position. The In addition, the rotation restricting shaft 314 is in contact with the inner peripheral edge upper end 315b of the rotation restricting groove 315 at the closed position, so that the rotation toward the closed position (counterclockwise rotation when viewed from the front) is restricted.

  Next, the opening / closing control for controlling the opening / closing operation of the second big prize opening 20c by the movable piece 20d configured as described above will be described with reference to FIGS.

  First, the game control CPU 56 is in a big hit state based on the fact that the big hit symbol corresponding to any one of “probability big hit A”, “probability big hit B”, and “non-probable big hit C (normal big hit C)” is stopped and displayed. In the case of shifting to, the opening / closing control for opening / closing the movable piece 20d is performed based on either a normal opening / closing control pattern or a high-speed opening / closing control pattern described later.

  The opening / closing control mentioned here refers to a closing control in which the movable piece 20d in the closed position is rotated toward the open position and then the movable piece 20c in the open position is rotated toward the closed position. This control is performed to open and close the movable piece 20d.

  In this embodiment, when the game control CPU 56 starts the opening control for exciting the solenoid 21B and rotating the movable piece 20d in the closing position toward the opening position when each round is started. After the movable piece 20d reaches the open position, the excitation of the solenoid 21B is released, and the movable piece 20d in the open position is controlled to rotate from the open position toward the closed position. A period until returning to the closed position is referred to as an open period. In addition, a period during which the movable piece 20d is maintained at the closed position between rounds (round interval) is referred to as a closed period.

  As shown in FIG. 20 (a), the game control CPU 56 determines that the first big hit symbol corresponding to “non-probable big hit C (normal big hit C)” and “probable big hit C” is stopped and displayed. When shifting to the big hit state (normally 12 round big hit state), the opening / closing control of the movable piece 20d is performed based on the normal opening / closing control pattern. In the normal opening / closing control pattern, the opening period (maximum opening period) in each round is about 29500 ms, and the closing period in the round interval is about 2000 ms.

  Further, as shown in FIG. 20B, the game control CPU 56 enters the second big hit state (high-speed 12 round big hit state) based on the fact that the big hit symbol corresponding to “probability big hit B” is stopped and displayed. In the case of shifting, the opening / closing control of the movable piece 20d is performed based on the high-speed opening / closing control pattern. In this high-speed opening / closing control pattern, the open period (maximum open period) in each round is about 150 ms, and the close period in the round interval is about 2000 ms. That is, in the high-speed opening / closing control pattern, the opening / closing control is shorter in the opening period than in the closing period.

  Next, details of the opening / closing control based on the normal opening / closing control pattern performed by the game control CPU 56 and the opening / closing state of the movable piece 20d by the opening / closing control will be described with reference to FIG. In the timing chart of FIG. 21, the detailed rotation position when the movable piece rotates between the open position and the closed position is shown in time series.

  The game control CPU 56 first excites the solenoid 21B with the start of the round (ta1). Thereby, the movable piece 20d in the closed position starts to rotate toward the open position. When the rotation restricting shaft 314 comes into contact with the lower end 315a of the turn restricting groove 315 when reaching the open position (ta2), it rebounds to the closed position side due to the impact at the time of contact, and then returns to the open position again. A return bounce operation is performed (ta3). Further, at this time, a rebound operation is performed in which the rebound to the closed position is once again bounced back to the open position again due to an impact when the rotation restriction shaft 314 comes into contact with the lower end 315a of the rotation restriction groove 315 (ta4). . After such a rebounding operation is repeated twice, the movable piece 20d is maintained in a stable state in the open position.

  As described above, such a rebounding operation is performed by, for example, the play provided between the clearance between the tips of the upper and lower catch pieces constituting the catch portion 325 and the rotation restricting shaft 314, the vertical width of the recess 322, and the like. This is caused by factors such as the presence of play provided between the connecting shaft 323 and the rebound force due to the impact of the contact exceeding the urging force of the coil spring 21c. In this embodiment, the rebound period ta2 to ta4 at the open position is about 45 ms.

  Further, in this embodiment, the rebounding operation is performed twice after contacting the lower end 315a in the open position until it is stably maintained in the open position, but the impact becomes weaker each time the rebound is repeated. Although the rebound stroke is also small, it may be stably maintained after repeating three or more times.

  Next, the game control CPU 56 releases the excitation of the solenoid 21B and starts the closing control (ta5) at a timing when a predetermined period (about 29423 ms) has elapsed since the opening control was started (ta1). As a result, the movable piece 20d starts to rotate toward the closed position by the urging force of the coil spring 21c.

  When the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 when reaching the closed position (ta6), it bounces back to the open position due to the impact at the time of contact, and then returns to the closed position again. A return bounce operation is performed (ta7). Further, at this time, a rebound operation is performed in which the rebound to the open position is once again bounced back to the closed position again due to an impact when the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 (ta8). . After such a rebounding operation is repeated twice, the movable piece 20d is maintained in a stable state in the closed position.

  Since the movable piece 20d is in an upright state in the closed position, the impact when the rotation restricting shaft 314 contacts the upper end 315b of the rotation restricting groove 315 is small compared to the open position where the movable piece 20d is tilted. The rebound operation is small, and the rebound period ta6 to ta8 is as short as about 35 ms.

  As described above, in this embodiment, when the movable piece 20d reaches the open position or the closed position, the rotation of the rotation restricting shaft 314 is restricted when the rotation is restricted to the lower end 315a or the upper end 315b of the rotation restricting groove 315. Since the rebounding operation is repeated due to the impact, a predetermined time is required until it is stably maintained in the open position or the closed position. Therefore, when the opening period is 29500 ms, the opening period is considered in consideration of the return period from the opening position to the closing position (ta5 to ta6, for example, about 42 ms) and the rebound operation period at the time of closing (ta6 to ta8, about 35 ms). It is only necessary to release the excitation of the solenoid 21B and start the closing control at a timing 77 ms before 29500 ms, that is, when a predetermined period of about 29423 ms has elapsed since the opening control was started.

  In the present embodiment, the total period of the opening period (ta1 to ta2, about 38 ms) and the bounce operation period (ta2 to ta4, about 45 ms) from the closed position to the opening position is about 83 ms. That is, a period (ta1 to ta4, about 83 ms) from the start of the opening control to the end of the rebounding operation at the opening position starts the opening control and then releases the excitation of the solenoid 21B to start the closing control. Therefore, in the normal opening / closing control pattern, it is not necessary to consider the rebound period at the open position.

  Next, details of the opening / closing control based on the high-speed opening / closing control pattern performed by the game control CPU 56 and the opening / closing state of the movable piece 20d by the opening / closing control will be described with reference to FIG. In the timing chart of FIG. 22, the detailed rotation position when the movable piece rotates between the open position and the closed position is shown in time series.

  First, the game control CPU 56 excites the solenoid 21B with the start of the round (tb1). Thereby, the movable piece 20d in the closed position starts to rotate toward the open position. Then, the rotation restricting shaft 314 comes into contact with the lower end 315a of the rotation restricting groove 315 by reaching the open position (tb2). Here, in the case of the normal opening control pattern, as described above, after rebounding to the closed position side by the impact at the time of contact, the rebounding operation to return to the open position is performed again, and then at this time The movable piece 20d is opened after a rebounding operation to return to the open position again after being rebounded again by the impact when the rotation restricting shaft 314 comes into contact with the lower end 315a of the rotation restricting groove 315 is performed. In the high-speed opening control pattern, the closed position is once again closed by the impact that the rotation restricting shaft 314 contacts the lower end 315a of the rotation restricting groove 315 in the high speed opening control pattern. At the timing (tb3) at which the movable piece 20d can be rotated toward the closed position before returning to the open position and completing the rebound action. To release the excitation of maytansinoid 21B to start the closure control.

  Specifically, the game control CPU 56 releases the excitation of the solenoid 21B and starts the closing control (tb3) at a timing when a predetermined period (about 40 ms) has elapsed since the opening control was started (tb1). As a result, the movable piece 20d starts to rotate toward the closed position by the urging force of the coil spring 21c.

  When the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 when reaching the closed position (tb6), it bounces back to the open position side due to the impact at the time of contact, and then returns to the closed position again. A return bounce operation is performed (tb7). Further, at this time, a rebound operation is performed in which the rebound to the open position is once again bounced back to the closed position again due to an impact when the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 (tb8). . After such a rebounding operation is repeated twice, the movable piece 20d is maintained in a stable state in the closed position.

  In this case, the total period when the opening period (tb1 to tb2, about 38 ms) and the rebounding operation period (tb2 to tb5 ′, about 45 ms) from reaching the opening position to the opening position is about 83 ms, and the opening control is performed. Is a period from the start of the opening to the end of the rebounding operation at the open position (tb1 to tb5 ′, about 83 ms), from the start of the opening control to the release of the excitation of the solenoid 21B to start the closing control Therefore, in the high-speed opening / closing control pattern, it is necessary to set the timing for starting the closing control without waiting for the end of the rebounding operation at the opening position.

  When the opening period is set to 150 ms, first, considering the return period from the open position to the closed position (for example, see ta5 to ta6, about 42 ms) and the rebounding operation period at the time of closing (tb6 to tb8, about 35 ms), At least about 77 ms before 150 ms when the opening period elapses, that is, at a timing before about 73 ms, which is a predetermined period after starting the opening control, the excitation of the solenoid 21B is released and the closing control is started. There is a need.

  Specifically, in this embodiment, the movable piece 20d is directed toward the closed position within the rebound period (tb2 to tb5 ′) from the closed position to the open position, bounced back at the open position, and returned to the open position again. Close control is started at the timing of starting rotation.

  In this embodiment, the timing at which the solenoid 21B is de-energized and the closing control is started is set to a time point (tb3) after about 40 ms has elapsed since the opening control is started, so that the movable piece 20d is in a rebound period. The rotation is started toward the closed position at a predetermined time (tb5) in (tb2 to tb5 ′). Note that the timing (tb3) at which the closing control is started takes into account that an error occurs in the time (tb1 to tb2, approximately 38 ms) until the movable piece 20d reaches the open position by the opening control. The time is later than the time (tb2) at which the opening position is reached.

  Here, in the case where the opening period is set to 150 ms, an example in which the rotation toward the closing position side by the closing control is started after passing through the rebounding operation period in the opening position will be described based on FIG.

  First, the game control CPU 56 excites the solenoid 21B with the start of the round (tc1). Thereby, the movable piece 20d in the closed position starts to rotate toward the open position. When the rotation restricting shaft 314 comes into contact with the lower end 315a of the rotation restricting groove 315 when reaching the open position (tc2), it bounces back to the closed position due to the impact at the time of contact, and then returns to the open position again. A return bounce operation is performed (tc4). Further, at this time, a rebound operation is performed in which the rebound to the closed position is once again bounced back to the open position again due to an impact when the rotation restriction shaft 314 comes into contact with the lower end 315a of the rotation restriction groove 315 (tc5). . After such a rebounding operation is repeated twice, the movable piece 20d is maintained in a stable state in the open position.

  The game control CPU 56 releases the excitation of the solenoid 21B and starts the closing control (tc3) at a timing when a predetermined period (about 52 ms) has elapsed since the opening control was started (tc1). As a result, the movable piece 20d starts to rotate toward the closed position by the urging force of the coil spring 21c.

  When the rotation restricting shaft 314 comes into contact with the upper end 315b of the turn restricting groove 315 when reaching the closed position (tc6), it bounces back to the open position side due to the impact at the time of contact, and then returns to the closed position again. A return bounce operation is performed (tc7). Further, at this time, a rebound operation is performed in which the rebound to the open position is once again bounced back to the closed position due to an impact when the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 (tc8). . After such a rebounding operation is repeated twice, the movable piece 20d is maintained in a stable state in the closed position.

  In this case, the timing (tc3) for releasing the excitation of the solenoid 21B and starting the closing control is later than the time (tc2) when the opening position is reached (tc2), and the first rebounding operation is completed and the opening position is reached again. Although the timing is before the time point (tc4), the movable piece 20d actually starts to rotate toward the closed position when the second rebounding operation ends (tc5).

  Therefore, since tc1 to tc2 is about 38 ms, tc2 to tc5 is about 45 ms, tc5 to tc6 is about 42 ms, and tc6 to tc8 is about 35 ms, the open period is about 160 ms. In this way, when the timing (tc3) is set such that the movable piece 20d starts to rotate toward the closed position after the first rebound operation is completed, the movable piece 20d is moved to the closed position side by the fluttering caused by the rebound action. Since the shift is likely to occur at the timing of starting rotation toward, the open period exceeds 150 ms.

  On the other hand, in the opening / closing control based on the high-speed opening / closing control pattern shown in FIG. 22, even if the movable piece 20d bounces off at the opening position, the rotation toward the closing position side is performed by the closing control before returning to the opening position again. By starting, there is no fluttering caused by the rebounding operation in the open position, so the solenoid 21B is de-energized and the closing control is started until the movable piece 20d starts to rotate toward the closing position. In addition to shortening the time, the rotational force applied to the closed position side is applied when starting the rotation toward the closed position side by the rebounding operation, and from that time (tb5) to the closed position. Since the rotational distance is also shortened, the open period can be set to about 150 ms even if the rebound operation period in the closed position is taken into consideration.

  In addition, the movable piece 20d starts to rotate toward the closed position at a predetermined timing (tb5) until the repetitive operation until the movable piece 20d bounces back to the closed position at the open position and returns to the open position again. However, at this timing (tb5), after returning to the closed position side by the rebounding operation, it starts to return to the open position side again (tb4), that is, when the amount of rebound to the closed position side becomes maximum (tb4). Since it is later than tb4), it rotates slightly toward the open position from the time point tb4 and then returns to the closed position, so that a slight wasteful movement occurs after the closing control is started. Become.

  Therefore, the solenoid 21B is excited so that the timing at which the movable piece 20d starts to rotate toward the closed position after the closing control is started is as close as possible to the time point (tb4) at which the amount of rebound to the closed position becomes maximum. It is preferable to set the timing for releasing the control and starting the closing control.

  Further, in this embodiment, in the high-speed opening / closing control pattern, rotation toward the closed position starts until the movable piece 20d bounces back to the closed position at the open position and returns to the open position again. The opening period is shortened by releasing the excitation of the solenoid 21B and starting the closing control at the timing to perform the above, but the control for preventing the rebounding operation in the opening position is rebounded even in the closing position. It is also possible to apply as control to prevent the operation from occurring.

  In this case, the solenoid 21B is excited at a timing at which the movable piece 20d starts to rotate toward the open position before the repetitive operation until the movable piece 20d bounces back to the open position at the closed position and returns to the closed position again. The opening control will be started.

  Here, another example of such an opening / closing control pattern will be described with reference to FIG. 24. First, the game control CPU 56 excites the solenoid 21B with the start of the round (td1). Thereby, the movable piece 20d in the closed position starts to rotate toward the open position. Then, reaching the open position, the rotation restricting shaft 314 comes into contact with the lower end 315a of the rotation restricting groove 315 (td2). The movable piece 20d is rotated toward the closed position at a predetermined time (td4) after the rebounding operation to return to the open position again after the bounce back to the closed position due to the impact at the time of contact. At a timing (td3) when the solenoid 21B can be released, the excitation of the solenoid 21B is released and the closing control is started.

  Then, the rotation restricting shaft 314 comes into contact with the upper end 315b of the rotation restricting groove 315 by reaching the closed position (td5). The movable piece 20d is rotated toward the open position at a predetermined time (td7) until the rebound operation for returning to the closed position is completed after the bounce back to the closed position due to the impact at the time of contact. The solenoid 21B is excited at the timing (td6) when the opening is possible, and the opening control is started.

  As described above, the control for starting the closing control at the timing at which the rebounding operation is not caused at the open position may be performed, and the control for starting the opening control at the timing at which the rebounding operation is not caused at the closed position may be performed. By doing in this way, it becomes effective in the case where the open period is continuously repeated without providing a long closed period between the open period and the open period.

  Further, as shown in FIG. 24, in a pachinko gaming machine that performs opening / closing control based on a high-speed opening / closing control pattern that is an example of an opening / closing control pattern that starts opening control at a timing that does not cause a rebounding operation in the closed position, FIG. It is also possible to perform the opening / closing control based on the normal opening / closing control pattern shown, and in this case, the game control CPU 56 starts the next opening period after the rebounding operation is completed at ta8 and the closing period is started, for example. The release control will be started at the timing of this.

  As described above, in the pachinko gaming machine 1 as the embodiment of the present invention, as shown in FIG. 22, the movable piece 20d as the movable member has the restriction shaft 314 in the rotation restriction groove at the open position. Even if there is a rebound due to an impact abutting against the lower end 315a of 315, the closing control is started so as to rotate toward the closed position before returning to the open position again by the rebound operation, so that in the open position It is possible to prevent the movable piece 20d from fluttering. Therefore, it is possible to easily bring the actual winning rate close to the winning rate intended by the designer because the occurrence of such fluttering prevents a large error between the designed opening period and the actual opening period. it can.

  Further, in the present embodiment, as the opening / closing control pattern, after the movable piece 20d is opened by the opening control, the restriction shaft 314 rebounds to the closing position side due to the impact abutting against the lower end 315a of the rotation restriction groove 315, A normal opening / closing control pattern in which the closing control is started at a timing (ta5) at which the movable piece 20d can be rotated toward the closing position side after being returned to the opening position and kept in contact with the lower end 315a for a predetermined period. (Open period 29500 ms). As described above, when the movable piece 20d is opened and closed for a longer period than the high-speed opening / closing control pattern, the movable piece 20d may be moved toward the closed position after the rebounding operation is finished and stabilized, so that the rebounding is performed. Since the start timing of the closing control can be changed without considering the period, it is easy to change the design of the opening period.

  In this embodiment, as shown in FIG. 24, the movable piece 20d as the movable member may be rebounded by an impact in which the restriction shaft 314 contacts the lower end 315a of the rotation restriction groove 315 in the closed position. However, the opening control is started so as to rotate toward the opening position before returning to the closing position again by the rebounding operation, thereby preventing the movable piece 20d from fluttering at the closing position. Therefore, it is possible to easily bring the actual winning rate close to the winning rate intended by the designer because the occurrence of such fluttering prevents a large error between the designed opening period and the actual opening period. it can.

  Further, in this embodiment, as the opening / closing control pattern, the movable piece 20d is closed by the closing control, and the restriction shaft 314 rebounds to the opening position side due to the impact abutting against the lower end 315a of the rotation restriction groove 315. A normal opening / closing control pattern for starting the opening control at a timing at which the movable piece 20d can be rotated toward the closed position side after being maintained for a predetermined period in the state of returning to the closed position and in contact with the lower end 315a (FIG. 21). Reference) and a high-speed release control pattern (see FIG. 22). As described above, when the movable piece 20d is opened and closed for a longer period than the high-speed opening / closing control pattern, the movable piece 20d may be rotated toward the open position after the rebounding operation is finished and stabilized. Since the start timing of the opening control can be changed without considering the period, it is easy to change the design of the opening period.

  Further, in this embodiment, as a period changing means capable of changing a period (for example, tb1 to tb3) from the start of the opening control to the start of the closing control, for example, a computer connectable to the game control board 31 There is dedicated software (not shown) to be activated. By doing in this way, it is possible to easily change the design of the opening period simply by changing the period from the start of driving of the movable piece 20d by the solenoid 21B to the start of reverse driving.

  Further, in this embodiment, a see-through window 102a is provided on the player side with respect to the game board surface with a predetermined gap L1 from the front surface of the game board 6 so that the game area 7 can be seen through from the player side. The movable piece 20d is provided so as to be rotatable between an open position and a closed position about a rotation shaft 20e standing on the front surface of the game board 6, and a length from the rotation shaft 20e to the tip. L2 is longer than the predetermined gap L1 (L1 <L2), so that the player can easily recognize the opening / closing operation, and the rebounding operation period becomes longer as the distance from the rotation center to the tip becomes longer. However, it is possible to easily bring the actual winning rate close to the designed winning rate simply by changing the start timing of the closing control or the opening control.

  Further, in this embodiment, the solenoid 21B is applied as an example of the driving means, and the game control CPU 56 sets the solenoid 21B in an excited state (on) in the opening control and applies a predetermined closing force (by the coil spring 21c) to the movable piece 20d. The movable piece 20d is changed toward the open position side by applying a force against the urging force), that is, the plunger 20b is contracted against the urging force by the coil spring 21c to move the movable piece 20d to the closed position side. Rotate toward. Further, in the closing control, the solenoid 21B is de-energized (off) and the movable piece 20d is turned to the closed position side by cutting off the force against the predetermined closing force (the urging force by the coil spring 21c) on the movable piece 20d. In other words, both the opening control and the closing control can be performed simply by exciting or releasing the solenoid 21B by extending the plunger 21b by the urging force of the coil spring 21c and rotating the movable piece 20d toward the opening position. It can be performed.

  In this embodiment, the rotation range of the movable piece 20 is determined by the restriction shaft 314 of the movable piece 20 being in contact with the lower end 315a and the upper end 315b of the rotation restriction groove 315. As described above, the open position restricting portion for restricting the movable piece 20d to abut at the open position and the close position restricting portion for restricting the contact at the closed position may be formed on a member other than the decorative member 307.

  In addition, although the normal opening / closing control pattern and the high-speed opening / closing control pattern as the embodiment of the present invention are applied to the second special variable winning ball device 20B, the first special variable winning ball device 20A and the variable winning ball device are described. 15 is also applicable.

  Next, the first special variable winning ball apparatus 20A will be described with reference to FIGS. 26 and 27. The first special variable winning ball apparatus 20A has a box-shaped main body with a first large winning opening 20a formed on the front surface. 410. In the main body 410, a first big prize passage 411 communicating with the first big prize opening 20a is formed, and an opening / closing drive mechanism 412 of the big prize opening door 20b for opening and closing the first big prize opening 20a is assembled.
