The gaming machine (1) is characterized by the above.

  The “entry ball” in the present invention is a concept including both simple entry (or passage) of a game ball that does not receive a prize ball and entry of a game ball that performs a predetermined number of prize balls. “Winning” is a concept that means the entry of a game ball that performs a predetermined number of prize balls. The term “big hit pre-stage” is a concept that means an intermediate stage process leading to a big hit.

  Note that the reference numerals in the parentheses are for comparison with the drawings, but this is for convenience to facilitate understanding of the invention and has no influence on the description of the claims. It is not a thing.

According to the first aspect of the present invention, the opening / closing control means controls the opening / closing body to open and close a predetermined number of times within a predetermined time when the jackpot pre-stage determination means determines that the jackpot pre-stage determination means, However, during the opening / closing operation of the opening / closing body by the opening / closing control means, it is determined whether or not a predetermined number of game balls have entered the second ball entry section, and the big hit generating means is the predetermined number of game balls. When it is determined that there is a winning ball, the big winning part is opened and a big win is generated. Therefore, when winning a big win, a predetermined number of the winning ball equivalent to the center bonus of the so-called second type pachinko machine The jackpot is actually generated (that is, after a predetermined number of balls are visually recognized and felt by a player or the like) at the time when the ball has been filled. This will make the process of mechanical lottery stand out more, make the process of winning the jackpot more effective and understand and feel more to the player, and the random number bias at the jackpot lottery in the first type pachinko gaming machine It is possible to realize a gaming machine that does not feel much to the player. Moreover, since the time required for one opening / closing operation is controlled to be shortened stepwise within a predetermined time, the player is trying to obtain a predetermined number of balls as an approach until the big hit occurs. , It is possible to advance the game while feeling a little surprise and novel gameability that it was difficult to enter the ball from a certain point in time when it was relatively easy at first. . Further, when the opening / closing control means determines that the first number of game balls have entered by the opening / closing operation of the opening / closing body in the first stage, the opening / closing time is made shorter than the first stage. Therefore, the entrance determination means determines whether or not the second number of game balls have entered, so that the opening and closing times are preset in the entrance process at each stage. If the number of entered balls is not cleared, the jackpot cannot be generated, and the player can advance the game while enjoying the thrill that the winning jackpot right may be lost.

  Hereinafter, as an embodiment of a gaming machine according to the present invention, a pachinko machine installed in a game hall or the like will be described with reference to the drawings. In the present embodiment, the gaming machine according to the present invention will be described as a pachinko machine (second type pachinko gaming machine) using a so-called second type special electric accessory. 1 is a front view showing an external structure of the pachinko machine 1 according to the present embodiment, FIG. 2 is an enlarged front view showing a game board 11 of the pachinko machine 1, and FIGS.

  In the present embodiment, the above-described specific winning opening 13, starting winning openings 14, 15, general winning openings 16, 16, the normal winning openings 28, 28 and the jackpot winning opening 30 in the center bonus 36 are all game balls. In the event that a is entered, it is controlled to win a predetermined game ball, but the normal winning holes 28 and 28 and the jackpot winning hole 30 are controlled as follows.

  That is, when the jackpot pre-stage determining means 77 (see FIG. 6) determines that the jackpot is in the pre-stage, the open / close bodies 22 and 22 are predetermined within a predetermined time (28 seconds in this embodiment) by the open / close body drive solenoid 39 (see FIG. 6). Whether or not a predetermined number (15 in this embodiment) of game balls has entered the winning holes 28, 28, and 30 during the opening / closing operation of the number of times (18 in this embodiment) is entered. It is determined by the sphere determining means 85.

  In the game area 11a, windmills 35 are disposed on the left and right upper and lower left and right sides of the center accessory 36, respectively. In addition, game balls that have been fired and fall without being involved in the center role 36 are appropriately scattered around the center role 36 in the game area 11a. A number of obstacle nails (not shown) are driven to guide the In the present embodiment, the windmill 35 is described as being disposed on the left and right upper and lower left and right sides of the center accessory 36. However, this is one example, and the position and number of the windmills 35 are the game area 11a. It does not specifically limit in the inside. In addition, even in the case of obstacle nails and various winning holes, there are no particular restrictions on the positions and number of the nails and the prize winning openings within the game area 11a.

  Next, the center accessory 36 will be described in detail with reference to FIG. A decorative member 74 that imitates the name and logo of the pachinko machine 1 is disposed above the center accessory 36, and a substantially trapezoidal opening provided in the center accessory 36 is disposed below the decorative member 74. A symbol display device 31 is disposed so as to be exposed from the portion 27.

The corrugated wall member 38 surrounds the center portion of the center accessory 36 from below the specific entrance 13. At the lower end of the wall member 38, that is, at the bottom of the center accessory 36, normal winning openings (second incoming portions) 28 and 28 for winning game balls introduced into the center accessory 36, and the winning opening 28 and 28, one jackpot winning entrance (second entrance section, jackpot entrance) 30 is arranged in a side-by-side state in which the respective openings are aligned in the horizontal direction and have the same height. ing.

  Next, the control system of the pachinko machine 1 in the present embodiment will be described with reference to FIG. That is, this control system is roughly composed of a game control device 60 and other peripheral devices such as a discharge control device 61.

  The game control device 60 is realized by an accessory control unit (not shown) mounted on the back surface of the game board 11, and is a one-chip microcomputer that performs an accessory control necessary for a pachinko game (ball game) or the like. A gaming microcomputer 62, a clock generation circuit (CLK) 63 that obtains a predetermined clock by dividing the oscillation frequency of the crystal, and an input / output interface 64 that inputs and outputs various signals. .

  The gaming microcomputer 62 includes a CPU 62a, ROM 62b, and RAM 62c, and is used as an LSI for an amusement chip. The gaming microcomputer 62 has an open / close control means 80, a big hit predetermination means 77, a pitch determination means 85, a big hit generation means 78, a big hit type selection means 83, and a switching control means 82 in the ROM 62b.

  When the opening / closing control means 80 receives a detection signal from the first winning port sensor 65 that has detected a winning at the starting winning port 14, the opening / closing control unit 80 controls the opening / closing member driving solenoid 39 to control the opening / closing members 22, 22. When the detection signal is received from the second winning port sensor 66 that has detected the winning at the starting winning port 15, the opening / closing body drive solenoid 39 is controlled to be opened and closed only once (0.5 seconds in this embodiment). Then, the opening / closing bodies 22 and 22 are opened / closed twice (in this embodiment, 1.0 second). The opening / closing control means 80 opens and closes the opening / closing bodies 22 and 22 a predetermined number of times (for example, 18 times) within a predetermined time (for example, 28 seconds) when the jackpot / early-stage determination means 77 determines that the position of the jackpot / previous stage has been determined. The time required for the opening / closing operation is controlled to be shortened stepwise within the predetermined time.

  In other words, the opening / closing control means 80 sets the opening / closing time of the opening / closing bodies 22 and 22 within a predetermined time (for example, 28 seconds) in two stages (for example, the previous stage opens for 1.9 seconds and then closes in 0.1 second). The operation is 10 times with an opening / closing time of 2.0 seconds, and the latter stage is to operate 8 times with an opening / closing time of 1.0 second each of which is opened for 0.9 seconds and then closed for 0.1 seconds). Control is made to shorten, and the pitch determination means 85 determines the number of pitches to the normal winning holes 28 and 28 and the big win winning slot 30 in each of the first and second stages in two stages. Then, the opening / closing control means 80, when the entrance determining means 85 determines that the first number (for example, 8) of game balls has entered by the opening / closing operation of the opening / closing bodies 22 and 22 in the first stage. The opening / closing time is made shorter than the first stage to shift to the second stage. These states can be understood from FIG. Even after the opening / closing time has passed the first stage and has shifted to the second stage, as shown in FIG. 7 (b), a detection signal indicating that the player has entered the normal winning holes 28, 28 and the big win winning opening 30 ( Detection pulse) occurs.

  The jackpot pre-stage determining means 77 determines the jackpot pre-stage according to the detection signal sent from the winning port sensor 67 when a game ball enters the jackpot winning port 30.

  The ball entry determination means 85 is based on detection signals from the prize opening sensors 67 and 81 during the opening / closing operation of the opening / closing bodies 22 and 22 by the opening / closing body drive solenoid 39 after the big hit front stage determination means 77 by the big hit front stage determination means 77. , 28 and the jackpot winning opening 30 in total, it is determined whether or not 15 game balls have entered. That is, in the second stage, the ball entering determination unit 85 adds the second number (for example, 7) of game balls to the predetermined number (for example, 15) in total with the first number (for example, 8). Determine if there is a ball. Here, the reason why the game balls enter the normal winning holes 28 and 28 and the jackpot winning hole 30 is referred to as “entry ball” because there is no prize ball corresponding to the entry of 15 game balls. That is, until the big hit front stage determination means 77 makes a big hit front stage determination, a prize ball to the dish unit 6 is performed. However, for the 15 game ball approach that is the condition until the big hit occurrence after the big hit front stage determination, Control is performed by a later-described release control device 61 (see FIG. 6) so that a winning ball is not performed.

  When the big hit generating means 78 determines that there are 15 game balls entered based on the detection signals from the winning hole sensors 67 and 81 after the big hit predetermination is determined by the big hit predetermination means 77. Then, the big winning opening 79 is opened to generate a big hit.

  The jackpot type selection means 83 determines the type of jackpot that is to be generated before the jackpot generating means 78 is opened by the jackpot generating means 78 after the winning hole sensor 67 and the winning hole sensor 81 determine that there is a ball. Select. This selection is determined by lottery based on a random number value stored in the ROM 62b, and there are two types of jackpot types to be selected: a normal jackpot and a special jackpot. That is, when a normal jackpot is selected (lottery), the player is made to acquire a large number of balls and then returns to the normal state before the jackpot. On the other hand, when the special jackpot is selected (lottery), the switching control means 82 reverses the functions of the normal winning holes 28 and 28 and the jackpot winning hole 30 to achieve the above-described certainty change state. In this probable state, even after the grand prize opening 79 is opened by a predetermined number of rounds (15 times in this embodiment) and a large number of balls are provided to the player, the game is played in an advantageous state for the player. You can progress. When a special jackpot is drawn, various light emission / display effects such as the effect lighting device 23 and the symbol display device 31 are performed by the game control device 60.

  When the special jackpot is selected by the jackpot type selecting means 83, the switching control means 82 functions as the jackpot entrance 30 as the regular entrances 28, 28, and the normal entrance 28, 28 serves as the jackpot winning opening. The control is performed so as to function as 30 so that the probability variation state appears. Then, when the probability variation state is not selected (that is, in the case of a normal jackpot), the functions of the normal winning ports 28 and 28 and the jackpot winning port 30 are set to their original states.

  The input / output interface 64 of the game control device 60 includes a first winning port sensor 65, a second winning port sensor 66, winning port sensors A1 and A2, a specific area sensor 76, and a winning port sensor 67 and a center hole 36. A detection signal from the winning prize sensor 81 is input. Here, the first winning port sensor 65 is a sensor for detecting a winning at the starting winning port 14, the second winning port sensor 66 is a sensor for detecting a winning at the starting winning port 15, and the winning port sensors A1, A2 are These are sensors that respectively detect winning in the general winning opening 16,16.

  The specific area sensor 76 is a sensor that detects the entry of a game ball into a specific area (continuation zone) provided in the special winning opening 79, and is a predetermined number of rounds that can be released when a big hit occurs (in this embodiment, 15 times). ) Is output to continue. The jackpot generating means 78 generates a jackpot and opens the grand prize winning hole 79, and then determines the presence or absence of the continuation signal for each round (that is, one opening), and the signal reaches a predetermined number of rounds. If it can be detected, the player is provided with all-round prize balls. However, when it is determined that the game has been interrupted in the middle of the predetermined number of rounds, the driving signal to the big prize opening / closing solenoid 75 is stopped and Close.

  The winning opening sensor 67 is a sensor that detects a gaming ball that has won the jackpot winning opening 30 among the gaming balls taken into the center accessory 36 by the opening / closing bodies 22 and 22 and outputs a V winning detection signal. The winning opening sensor 81 is a sensor that detects winning in the normal winning openings 28 and 28, respectively. If there are N normal winning holes 28, N winning hole sensors are also provided correspondingly.

  On the other hand, from the input / output interface 64, the sound output device 68 that performs sound emission driving to control the output of sound effects, the sound output control device 68 that controls the sound output, the effect lighting device 23, the symbol display device 31, and the like are controlled. A device 69, an opening / closing body drive solenoid 39 for driving the opening / closing bodies 22 and 22 of the center accessory 36, a large winning opening opening / closing solenoid 75 for opening / closing the large winning opening 79, and a firing control device 71 for controlling the launching device 72, respectively. A signal is output.

  Further, a signal of prize ball control information is output from the input / output interface 64 to the release control device 61. As the contents of the prize ball control information, information such as prize ball number information and release conditions is output. The release control device 61 controls to release a game ball by driving a release unit (not shown) based on prize ball control information input from the game control device 60. That is, when the game control device 60 detects a winning by the first winning mouth sensor 65, the second winning mouth sensor 66, the winning mouth sensors A1 and A2, and the winning mouth sensors 67 and 81 corresponding to each winning mouth, Information on the number of winning balls set in advance corresponding to the winning value of the winning opening is transmitted to the discharge control device 61. When receiving the prize ball number information, the release control device 61 executes prize ball control according to the information and releases the game ball to the dish unit 6.

  Next, the operation of the pachinko machine 1 will be described with reference to the flowcharts of FIGS.

  That is, when a player seated facing the pachinko machine 1 holds the launch handle 9 and rotates it to an appropriate angle, the launch control device 71 controls the launch device 72 in accordance with the pivot angle, By actuating the launching device 72, the game balls are continuously launched into the game area 11a at predetermined time intervals. Then, the game ball that is launched into the game area 11a and rolls down falls in time in the winning holes 14, 15 or the like, or rolls and falls without being involved in these, and the out hole at the bottom of the game area 11a. 18 is discharged to the back side of the game board 11.

  When a game ball wins the first winning opening 14 (step S 1), the opening / closing bodies 22, 22 provided in the center accessory 36 are operated once by the operation of the opening / closing body driving solenoid 39 controlled by the opening / closing control means 80. Is opened and closed (in this embodiment, 0.5 seconds) (step S2). When a game ball wins the second winning opening 15 (step S1), the opening / closing bodies 22 and 22 are opened and closed twice by the operation of the opening / closing body drive solenoid 39 under the control of the opening / closing control means 80. In the embodiment, 1.0 second is performed (step S2). When the specific entrance 13 is in the open state in this way, when the game balls that have passed through the vicinity of the center accessory are picked up by the opening / closing bodies 22, 22 so that the opening / closing bodies 22, 22 are opened and closed in time. The game ball is introduced into the center accessory 36 from the specific entrance 13.

  The introduced game ball falls in the center object 36 and travels to the normal winning holes 28 and 28 and the big win winning opening (V zone) 30. Meanwhile, the gaming microcomputer 62 determines whether or not there is a detection signal from the winning hole sensors 67 and 81, and determines whether or not a winning is made in the center accessory 36 (step S3). If it is determined, it is determined whether or not the jackpot winning opening 30 is won (step S4). As a result, in the case of winning the jackpot winning opening 30, the jackpot pre-stage determining means 77 determines that the jackpot pre-stage is determined, and the opening / closing control means 80 is a predetermined number of times within a predetermined time (28 seconds in this embodiment) ( In this embodiment, the opening / closing body drive solenoid 39 is controlled so as to open / close the opening / closing bodies 22, 22 (step S5).

At this time, the opening / closing control means 80 performs a single opening / closing operation while opening / closing the opening / closing bodies 22 and 22 a predetermined number of times (for example, 18 times) within a predetermined time (for example, 28 seconds) at the time of the jackpot pre-stage determination. In order to control the required time to be shortened stepwise within the predetermined time, first, n ₁ second is set as the first step. In other words, after opening for 1.9 seconds (n ₁ second), the operation is performed 10 times (that is, 20 seconds) with each opening / closing time of 2.0 seconds closing at 0.1 seconds (step S6). Then, when the entrance determining means 85 determines that there are a total of x (for example, 8) or more entrances, that is, substantially x entrances (step S7), the opening / closing control means 80 As a stage, n ₂ seconds shorter than n ₁ second are set. In other words, the operation is performed 8 times (that is, 8 seconds) with each opening / closing time of 1.0 second that is closed for 0.1 second after being opened for 0.9 second (n ₂ seconds) (step S8). Thereafter, in step S10, it is determined whether or not there are y or more balls.

  If it is not determined in step S7 that there are x balls, it is determined in step S9 whether the opening / closing frequency (10 times) of the opening / closing bodies 22 and 22 in a predetermined time (20 seconds) has been cleared, If it is cleared, the process is terminated and the jackpot right is extinguished. If not cleared, step S7 is repeated. If it is not determined in step S10 that there are y (for example, seven) balls, the number of opening / closing operations (8 times) of the opening / closing bodies 22 and 22 in the predetermined time (8 seconds) is cleared in step S11. If it is cleared, the process is terminated and the jackpot right is extinguished. If not cleared, step S10 is repeated.

  On the other hand, when the entrance determination unit 85 determines that there are more than y entrances, that is, substantially y entrances in step S10, the jackpot type selection unit 83 generates the jackpot type to be generated. Are lottery (step S16). At this time, the opening / closing control means 80 stops the opening / closing body drive solenoid 39 to close the opening / closing bodies 22, 22.

  Then, in step S17, it is determined whether or not the jackpot type selected in step S16 is a special jackpot for acquiring the probability variation state. If the jackpot type is a special jackpot, in step S18, the game control device 60 After various lighting / display effects such as the effect lighting device 23 and the symbol display device 31 are made, the switching control means 82 causes the jackpot entrance 30 to function as the normal entrances 28, 28. , 28 are controlled to function as the jackpot winning opening 30 and the state of the center bonus 36 is changed so that winning in the jackpot winning slot 30 (that is, the V zone) is facilitated (step S19). The jackpot generating means 78 opens the jackpot 79 and generates a jackpot (step S12). On the other hand, when it is determined in step S17 that it is not a special jackpot (that is, a normal jackpot), the process proceeds to step S12 as it is, and the jackpot 79 is opened to generate a jackpot.

  Of the game balls that are launched into the game area 11a, the one that flows down toward the open big winning opening 79 wins. Meanwhile, the jackpot generating means 78 determines whether or not there are z (for example, 10) winnings (or whether or not N seconds (for example, 15 seconds) have passed) (step S13), and there are z winnings. The special winning opening 79 is once closed at the time (or when N seconds have elapsed) (step S14). At this time, the jackpot generating means 78 determines the presence / absence of a continuation signal from the specific area sensor 76 every round (step S27), and opens and closes the big prize opening 79 while the continuation signal continues in each round. When the operation (round operation) is repeated and the number of times reaches N (that is, 15 times) at the maximum (step S28), or when the continuation signal of the specific area sensor 76 is not obtained in step S27, the big hit ends. The winning opening 79 is closed. In this way, a large number of game balls are paid out to the dish unit 6 by winning a plurality of rounds. And a player will continue the game in the above-mentioned probability change state or a normal state from the end of jackpot.

  In the present embodiment, a configuration is made such that when a total of 15 game balls enter the normal winning openings 28, 28 and the big win winning opening 30, the big winning opening 79 is opened to generate a big win. The prize ball for the 15 balls entered was not performed, but the prize ball for the 15 balls entered may be configured.

  Further, in this embodiment, the hit determination means 85 is a big hit when there are x + y (for example, 15) or more balls, but as another embodiment, the hit state is changed according to the number of balls entered. It can also be configured to be selected. For example, if there are 15 or more balls, it is a big hit (15 rounds), if there are 13 or more balls, medium hits (8 rounds), if there are 10 or more balls, it is a small hit ( 2 rounds), and the ranking is based on the visible state, that is, the number of entered balls. In this way, more hits can be provided to the player. In addition, in a conventional pachinko machine, the player can deal with a game machine in which the number of rounds is determined by an internal lottery (for example, 2Ror15R) despite being a big hit. Can eliminate the feeling of opacity and unfairness.

  Further, in the present embodiment, when the transition to the above-described probability variation state is made, for example, after 15 balls have been entered, the big winning opening 79 is opened to generate a big hit, but other configurations are also possible. Is possible. For example, when shifting to a certain change state, control is performed so as to reduce the number of entered balls required for the determination to the center accessory 36, and after the ten balls have been entered, the big winning opening 79 is opened or 5 It can also be configured to open the grand prize opening 79 after the individual ball is present.

  As described above, according to the present embodiment, when the opening / closing control means 80 determines that the big hit pre-stage determination means 77 is the big hit pre-stage, the open / close bodies 22 and 22 are opened / closed a predetermined number of times within a predetermined time. The ball determining means 85 determines whether or not a predetermined number of game balls have entered the normal winning holes 28 and 28 and the big hit winning opening 30 during the opening / closing operation, and the big hit generating means 78 has a predetermined number of gaming balls. When it is determined that there is a ball, the big prize opening 79 is opened to generate a big hit. For this reason, when a jackpot is won in the jackpot lottery, a jackpot is actually generated when a predetermined number of balls are entered into the center bonus 36 corresponding to the center bonus of the so-called second type pachinko machine (ie, This occurs after a predetermined number of balls have been visually recognized and felt by a player or the like). This will make the process of mechanical lottery stand out more and make the process of hitting the jackpot more effective and understand more and more realistically by the player, and the random number bias at the jackpot lottery in the first type pachinko game machine And a pachinko machine that does not make players feel much. Moreover, since the time required for one opening / closing operation is controlled to be shortened stepwise within a predetermined time, the player is trying to obtain a predetermined number of balls as an approach until the big hit occurs. , It is possible to advance the game while feeling a little surprise and novel gameability that it was difficult to enter the ball from a certain point in time when it was relatively easy at first. .

  In addition, when the opening / closing control means 80 determines that the entry determining means 85 has entered the first number of game balls by the opening / closing operation of the opening / closing bodies 22, 22 in the first stage, the opening / closing time is set to the first time. Since the entry determination means 85 determines whether or not the second number of game balls have entered, the entry process at each stage with different opening and closing times is made shorter than the first stage and shifted to the second stage. Therefore, if the preset number of entered balls is not cleared, the jackpot cannot be generated, so the player can proceed with the game while enjoying the thrill that the jackpot right that was obtained may disappear. it can.

  Further, when opening / closing the opening / closing bodies 22 and 22, the ratio of whether or not to enter the ball is determined by adjusting a game nail (not shown) struck in the game area 11a. In addition to being able to change the jackpot probability individually according to the degree of the game, the player can predict which game machine is likely to hit a big hit out of a plurality of gaming machines by observing and comparing the adjustment state of the game nail, so the conventional first Compared to the seed pachinko, the level of technical intervention between the hall manager and the player is further improved.
