BACKGROUND OF THE INVENTION
The present invention relates to a game machine such as a ball game machine represented by a pachinko game machine, and in particular, a launching means for launching a game ball toward a game area of a game board in accordance with a player's launch operation, and a predetermined condition The present invention relates to a gaming machine equipped with firing ball number reducing means for reducing the number of shot balls fired by the launching means per unit time when established.
[0002]
[Prior art]
In a gaming machine such as a pachinko gaming machine, the gaming ball is configured to be continuously fired by a launching means constituted by a motor, a solenoid, or the like to a gaming area of the gaming board, and the launched gaming ball A hit / decision is determined due to the establishment of a predetermined determination start condition such as entering a start winning opening provided in the game area, and when the determination result is a win, a predetermined called “big hit” There are models that are configured to perform special games. In such a model, a determination result display means for displaying a determination result of the hit or not, such as a liquid crystal, a dot matrix, or an LED display device which normally displays a plurality of symbols composed of numbers, symbols or pictures. Is provided on the game board.
[0003]
In general, the determination result display means is capable of variably displaying, for example, by scrolling a plurality of symbols and then stopping the display. Then, the symbols displayed on the determination result display means start to change due to the establishment of the determination start condition, and after a predetermined time change, a plurality of symbols are stopped and displayed on the determination result display means, respectively. When the combination of the stop symbols is a specific combination (big hit symbol combination), a “big hit” is formed, and when the combination of other symbols (outgoing symbol combination) is “off”. In the case of the “big hit”, a special game such as a large winning opening provided in the game area is continuously opened to enable a large number of winnings, and a large amount of prize balls are paid out during the winnings. Is to be executed.
[0004]
In the above gaming machine, the special game is executed when a predetermined condition is satisfied when the jackpot is established, for example, when a predetermined combination of symbols having a jackpot is established, for example. After completion of the special game, a privilege different from the special game privilege, for example, increasing the chance of determination by the success / failure determination means by changing the start winning opening to a state where the game ball is easy to enter, Special benefits such as shortening the special symbol change time (the time from the start of symbol change until the last stop symbol is stopped and displayed) in the result display means, and changing the probability of the next jackpot decision to a high probability are given to the player. A model configured to execute a privilege game is widely spread.
[0005]
Conventionally, in this type of gaming machine, the number of game balls that can be fired by the launching means per unit time, that is, the number of fired balls is always a predetermined number (specifically, about 100 balls per minute). ) To be constant. In addition, the number of hit determination information that can be accumulated in the gaming machine (more specifically, storage means such as a RAM), in other words, the entry to the start winning opening that becomes the determination start condition of the hit A predetermined possible memory number (upper limit) is set as the memory number (the number of reserved balls), and a game profit (prize item) as a mere win without determining whether or not the ball is more than the possible memory number. It is common to give a player only the payout of a ball).
[0006]
For this reason, during a bonus game that increases the chance of determination by the success / failure determination means by changing the start winning opening to a state where it is easy to enter a game ball, the number of stored balls in the starting winning opening is immediately filled. It is easy to become. In the state where the number of memories is full, when a large number of balls that cannot be a hit determination start condition occur, the game ball is wasted in terms of acquisition of a hit determination opportunity. This could be disadvantageous for the player.
[0007]
In order to eliminate such inconvenience, the player stops (stops) the shooting operation by releasing his / her hand from the operation unit of the shooting means when the number of balls stored in the starting prize opening becomes full. It is also referred to as hitting or single shot, etc.)), and there are many cases where the waste of game balls in the determination of success / failure is reduced. However, the act of stopping the firing operation and the subsequent act of restarting the firing operation are troublesome for the player. In addition, since it is difficult to adjust the strength of the game ball when resuming the launch operation, there is a possibility that the degree of disadvantage of the player may be determined according to the player's intuition and skill.
[0008]
In recent years, a single-shot switch (launching stop switch) is provided in the operation part of the launching means, and the operation of the launching motor is stopped by switching the switch. You can see models that can stop the launch of the ball. However, even in such a model, it is necessary to stop and restart the firing operation, which is still troublesome for the player.
[0009]
[Problems to be solved by the invention]

In addition, a winning ball count switch for detecting a game ball that has entered the grand winning port 15 and has not entered the specific area winning port 63 is provided in the approximate center of the big winning port 15. .
[0024]
The operation of the special symbol display device 43 and the operation of the special winning opening 15, that is, the operation when the special game is executed (when the big hit is established) will be described. As described above, when a game ball enters the first type start winning ports 10 and 11 and a ball is detected by the special symbol variation start switch, a counter for determining success / failure in the main control circuit 70 shown in FIG. 4 to be described later. Information such as random number values of various random counters is acquired (extracted), and the determination information is temporarily stored in the RAM 73 of the main control circuit 70. Based on the stored information, determination of jackpot, determination (creation) of stop symbol, selection of symbol variation pattern such as reach determination, etc. are performed, and the left side of the image display unit 50 of the special symbol display device 43 The change of the special symbol is started in the display area, the center display area, and the right display area.
[0025]
After a predetermined time from the start of the change of the special symbol (the time determined by each selected change pattern, in this example, a minimum of 5.1 seconds to a maximum of 57.1 seconds), for example, the left display area, the center display The special symbols fluctuate and stop in the order of the region, the right display region, the left display region, the right display region, the center display region, etc., and the stop symbol is fixedly displayed. At this time, the reach state may be established depending on the determined stop symbol, symbol variation pattern, and the like. Here, the reach state refers to a specific display mode, that is, a jackpot combination, in a stage before the display control is advanced and the display result is stopped and displayed after the special symbol is started to be variably displayed on the image display unit 50. A display mode for making the player think that the variable display mode is easy to be displayed. In this embodiment, as one of the reach states, a display area for displaying the last stop symbol, in this case, only the central display area is left out of the display areas of the image display unit 50, and the remaining two display areas are used. A display mode is provided in which the symbols are stopped and displayed so that the symbols become a specific combination (for example, the same symbol).
[0026]
When the combination of the stop symbols is a jackpot symbol combination determined in advance, for example, a common name consisting of a combination of the same symbols, the state shifts to a jackpot state. When the big hit state is reached, the open / close plate 61 of the grand prize opening 15 is opened and the game ball falling on the surface of the gaming area 6 is received, and it is possible to enter the big prize opening 15. If there is, a predetermined number of game balls are paid out as prize balls by a prize ball payout device (not shown). The opening / closing plate 61 is closed after a predetermined time (for example, 29.5 seconds) elapses or when the number of balls detected by the winning ball count switch reaches a predetermined number (for example, 10). . The number of balls detected by the winning ball number count switch is displayed on the image display unit 50 of the special symbol display device 43 as a number from 0 to 10 or as a bar graph.
[0027]
In addition, when the special winning ball detection switch detects that a special ball winning port 63 has been entered within about 2 seconds after the big winning port 15 is opened or within about two seconds after the big winning port 15 is closed, the right to continue repeating the big hit again. And the opening and closing of the opening / closing plate 61 is repeated a predetermined maximum number of times (for example, a maximum of 15 times). Note that the gaming machine 1 according to the embodiment belongs to the first-type continuous-instrument-type pachinko gaming machine (also referred to as a seven machine or a digipachi) based on the operation contents of the image display unit 50 and the special prize opening 15. Can be said.
[0028]
Furthermore, in this embodiment, the jackpot symbol combination displayed on the image display unit 50 when the jackpot is established is a bonus game symbol '1', '3', '5', '7', '9', '11. When the number is any odd number of ', the bonus game executing means (corresponding to a main control circuit 70 described later) increases each determination opportunity, determination result display time, and probability variation described below. A privilege game for granting a privilege to a player is executed after the end of the special game.
[0029]
The increase in the determination opportunity is to increase the chance of the hit / fail determination by the determination unit, and specifically, according to an instruction from the determination opportunity increase means (here, the main control circuit 70) in the privilege game execution means. Further, the time for expanding and opening the lower first type start winning opening 11 by the normal symbol (small hit), that is, the duration of the second state in which the game ball is easy to enter, is increased, or the normal symbol display device 41 is used. The frequency of occurrence of the second state of the lower first type start winning port 11 (expanded open state of the lower first type start winning port 11) is increased by shortening the fluctuation time of the normal symbol of Thus, a plurality (two or more) of the game balls easily enter the lower first type start winning opening 11 and one (one time) entering the starting winning openings 10 and 11. ) Is stored in the storage means, and a plurality of times Such that to perform the propriety determination of twice or more) can be mentioned. When the number of chances of hit / decision is increased in this way, the memory of the ball entering the first type start winning holes 10 and 11 is immediately filled (specifically, in the embodiment, except for the currently displayed symbol variation display). 4).
[0030]
The determination result display time reduction is a special in the image display unit 50 of the special symbol display device 43 in accordance with instructions from the determination result display time reduction means (here, the main control circuit 70 and the display control circuit 90) in the privilege game execution means. The symbol variation time, that is, the time required for displaying the determination result is made shorter than usual. If the determination result display time is shortened in this way, the progress of the game is accelerated. In this embodiment, the time required from the start of change of the special symbol in the normal gaming state (when the determination result display time is not shortened) to stop is 8.5 seconds (when there is no reach action display). On the other hand, the time required from the start of the change of the special symbol to the stop in the bonus game state (when the determination result display time is shortened) (but no reach action display) is 5.2 seconds.
[0031]
Probability variation means that the probability of jackpot occurrence due to determination of success / failure according to an instruction from probability variation means (in this case, main control circuit 70) in the bonus game execution means, is a normal probability state with low probability (low probability state, 1 in this embodiment). /315.5) is changed to a probability fluctuation state (high probability state, 5 / 315.5 in this embodiment) with a high probability. When the probability changes in this way, the player can easily win the jackpot early.
[0032]
Further, in this embodiment, the big hit symbol combination when the big hit is established is an even number of any one of “0”, “2”, “4”, “6”, “8”, “10” which is a normal symbol. When it is a rough game, after the big hit, the game is set to a normal gaming state where there is an increase in the determination opportunity, the determination result display time is reduced, and there is no probability variation, and the normal gaming state continues until the next big hit. On the other hand, when the big hit is established again in the above-mentioned bonus game symbols in the bonus game execution state, the bonus game execution state is entered again after the jackpot ends.
[0033]
In this embodiment, the bonus game is determined according to the jackpot symbol combination (symbol type) when the jackpot is established. However, the present invention is not limited to this. Whether or not the privilege game is executed may be determined according to a lottery result or the like produced by the movement of the picture (character) after the stop display (after the big hit is established).
[0034]
In this embodiment, the bonus game is executed after the end of the special game, but the present invention is not limited to this. The bonus game may be executed during the special game, or the bonus game may be executed both during the special game and after the special game ends. Further, regardless of whether the bonus game is a big hit or not, the bonus game is executed when a predetermined condition is satisfied, for example, when the number of consecutive hits in the hit / fail determination reaches a predetermined number of times. You may do it. In addition, in the embodiment, the end of the bonus game is until the next jackpot is established, but not limited to this, for example, the number of times or the maintenance time of the bonus game is a predetermined number or time The bonus game may be terminated when the time has come.
[0035]
Furthermore, the content of the bonus game is not limited to the above-described examples, and for example, the number of prize balls for winning a prize during execution of the bonus game may be increased more than the normal prize. Further, in this embodiment, the privilege game is one type in which all of the determination opportunity increase, the determination result display time reduction, and the probability variation are all performed as described above. It may be set as above. In addition, as a method of making two or more types of privilege games, for example, changing the privilege combined with the increase in the determination opportunity, the number of game maintenance times (executable number of times) and game maintenance with the same game content (privilege content), for example For example, a plurality of privilege games having different times (executable times) may be prepared to further subdivide the various types of privilege games.
[0036]
Next, the launching means F and the like will be described in detail. As can be understood from FIG. 3, the firing means F swings intermittently by the operation handle F1, a firing motor F2 including a stepping motor driven by the operation of the operation handle F1, and the driving of the firing motor F2. Thus, it has a striking ball F3 for projecting and firing game balls, a launching means control board F4, and the like. The symbol F5 shown in the figure is a handle body of the operation handle F1, F6 is an operation lever of the operation handle F1, F7 is a single-shot switch (firing stop switch) provided on the operation handle F1 for forcibly stopping the launch of the game ball, F8 is a motor base of the firing motor F2, F9 is a plate cam directly connected to the rotation shaft (motor shaft) of the firing motor F2, and F10 is an operating pin provided on the ball striking rod F3 so as to be able to contact and separate from the plate cam F9. , F11 is an upper rubber that absorbs impact when the hitting ball F3 swings, F12 is also a lower rubber, F13 is a wire for hitting ball, F14 is a game ball launch adjusting dial, F15 is a hitting ball F3 and a game ball A tension spring stretched between the firing adjustment dial F14, F16 is a pulley unit that changes the amount of rotation of the game ball launch adjustment dial F14, and F17 is a game ball launch adjustment die. Linear transmission member connecting the Le F14 and the pulley unit F16, F18 base, F19 handle base, F20 is a touch sensitivity adjustment volume.
[0037]
In the embodiment, the operation lever F6 and the like of the operation handle F1 is made conductive, and connected to the launching unit control board F4 (more specifically, its touch switch circuit) via a lead wire or the like. The firing means control board F4 is connected to the firing motor F2 by a lead wire or the like. As a result, when the player's hand touches the operation handle F1 such as the operation lever F6, the firing means control board F4 detects the handle ground input signal, and the firing motor F2 starts to rotate, and accordingly. The plate cam F9 can be rotated.
[0038]
The operation of the firing means F will be described. When the plate cam F9 rotates, the operating pin F10 of the hitting ball F3 rolls on the outer periphery of the plate cam F9, and the hitting ball F3 is caused by the force of the tension spring F15. It swings on the contrary. Then, at the moment when the operating pin F10 is removed from the outer periphery of the plate cam F9, the hitting ball F3 is swung back to the original position by the tensile force of the tension spring F15. The game balls sent one by one on the firing rail (not shown) are launched by a feeding cassette (not shown). Further, when the amount of rotation of the operation lever F6 (usually the amount of rotation in the right direction) is changed, the tension of the tension spring F15 is increased as the amount of rotation of the game ball firing adjustment dial F14 is changed by the pulley unit F16. The force changes, and the player can launch the game ball at an arbitrary position above the game area 6 by adjusting the tensile force. Further, when the one-shot switch F7 of the operation handle F1 is pressed, the firing motor F2 is stopped, so that the player can fire the game balls one by one. Here, in this embodiment, when the plate cam F9 directly connected to the rotation shaft of the launch motor F2 makes one revolution, one game ball is launched, and in the normal game state (the bonus game is not executed). Since the firing motor F2 is set to rotate about 100 times per minute at the time), the number of fired balls per minute in the normal gaming state is about 100 balls.

[0050]
Furthermore, the launch control circuit 100 is connected to a launch motor F2 of the launch means F and a handle ground (corresponding to the operation lever F6 of the operation handle F1, etc., also referred to as a touch switch). The launch control circuit 100 corresponds to the launch means control board F4.
[0051]
The firing control circuit 100 and the main control circuit 70 play a role as a firing ball number reducing means for reducing the number of firing balls fired by the firing means F per unit time, and execute the above-described privilege game. The number of fired balls per unit time in the launching means F (in the embodiment, the number of revolutions of the launch motor F2 per unit time) is automatically reduced from the normal time.
[0052]
In this embodiment, hit determination information (specifically, a random value such as a big hit determination counter, etc.) that is being executed in the bonus game and that is accumulated and stored in the RAM (storage means) 73 of the main control circuit 70. ), That is, the number of change-holding spheres is less than the number of possible memories stored in the RAM 73 (here, four except for those currently changing special symbols (five if including those currently changing special symbols))) The number of firing motors F2 per minute is increased by the action of the firing ball number reducing means when the number exceeds a specific number (for example, 3 or 4 (excluding those currently changing special symbols)). The number of revolutions is decreased, and the number of fired balls is automatically reduced from the normal time (for example, 70 balls / minute). Hereinafter, a specific example of the launch control circuit 100 will be described.
[0053]
As shown in the block diagram of FIG. 5, the launch control circuit 100 according to the embodiment includes an oscillation circuit 101, a frequency divider 102 that receives an output from the oscillation circuit 101 and outputs a signal at a preset time interval, A first AND gate 103 and a second AND gate 104 that control a signal from the frequency divider 102 to a signal corresponding to the number of shot balls set by the main control circuit 70 (more precisely, ROM 74), and a handle ground (touch switch) ) A third AND gate 105, a fourth AND gate 106, a fifth AND gate 107, and a third AND gate 105 for operating the firing means F when the ON state and the single switch F7 are in the OFF state (ON state as the firing means F). Alternatively, a mode in which a pulse signal is sent to the firing motor (stepping motor) F2 in accordance with the signal from the fourth AND gate 106. And a chromatography driving circuit (driver) 108.
[0054]
In this embodiment, as described above, each time the rotation shaft (output shaft) of the launch motor F2 makes one revolution, the hitting ball F3 operates once to launch one game ball at the launch position. Further, as the firing motor F2, a motor that rotates the rotating shaft once by 240 pulses (the rotating shaft rotates 1.5 degrees by one pulse) is used. The oscillation circuit 101 oscillates at a frequency of 3270000 Hz. As a result, the frequency divider 102 sets the frequency division ratio to 8192, 11679 in advance, receives a signal from the oscillation circuit 101, and the number of shot balls per minute depends on the frequency division ratio of the frequency divider 102. A signal for 100 balls (400 Hz = 24,000 pulses / minute: normal firing ball number control signal) and a signal for the number of firing balls of 70 balls per minute (280 Hz = 16800 pulses / minute: motor slow firing ball number control signal) are output. Like to do. Note that the frequency division ratio of the frequency divider 102 is not limited to the above value, and by appropriately setting the frequency division ratio, the number of rotations (rotational speed) of the firing motor F2 can be appropriately set. .
[0055]
In the above configuration, in the case of normal firing ball number control, that is, when the number of firing balls of 100 balls per minute is set by a command of the main control circuit 70 in the normal gaming state in which the privilege game is not executed, the main control circuit 70 H signal enters one input side of the first AND gate 103. Since the first AND gate 103 receives the signal from the frequency divider 102 as the other input, when the H signal is input in response to a command from the main control circuit 70, the H signal and the H signal from the frequency divider 102 are input. Thus, a normal firing ball number control signal is output, and this signal enters one input side of the third AND gate 105. Further, since the third AND gate 105 uses the output from the fifth AND gate 107 as the other input, if the input side from the fifth AND gate 107 is an H signal, that is, the player touches the operation handle F1. If the single switch F7 is in the OFF state (the ON state as the launching means F), the third AND gate 105 opens and sends the normal firing ball number control signal from the frequency divider 102 to the motor drive circuit 108. Then, a pulse signal for 100 balls per minute is sent from the motor drive circuit 108 to the launch motor F2, and the launch motor F2 rotates 100 times per minute, thereby playing game balls at a rate of 100 balls per minute. Fire.
[0056]
On the other hand, in the case of motor throwing ball number control, that is, in this embodiment, the bonus game is being executed, and the number of the variation holding balls is three (however, except for those currently changing special symbols) .) As described above, when the number of shots of 70 balls per minute is set by the command of the main control circuit 70, the H signal from the main control circuit 70 enters one input side of the second AND gate 104. Since the second AND gate 104 receives the signal from the frequency divider 102 as the other input, when the H signal is input in response to a command from the main control circuit 70, the H signal and the H signal from the frequency divider 102 are input. Thus, the motor throw ball number control signal is output, and this signal enters one input side of the fourth AND gate 106. Since the fourth AND gate 106 uses the output from the fifth AND gate 107 as the other input, if the input side from the fifth AND gate 107 is an H signal, that is, the player touches the operation handle F1. If the single switch F7 is in the OFF state (the ON state as the launching means F), the fourth AND gate 106 opens and sends the motor throw ball number control signal from the frequency divider 102 to the motor drive circuit 108. Then, a pulse signal for 70 balls per minute is sent from the motor drive circuit 108 to the launch motor F2, and the launch motor F2 rotates 70 times per minute, thereby playing game balls at a rate of 70 balls per minute. Fire.
[0057]
Next, the main motor control process (S1), the sub motor control process (S10), the start winning opening release process (S20), etc. executed by the main control circuit 70 and the launch control circuit 100 in the gaming machine 1 will be described. A simple flow will be described.
[0058]
In the main motor control process (S1), as understood from the flowchart of FIG. 6, first, it is determined whether or not the special game execution flag A1 is 1, that is, whether or not the special game is being executed (hit a big hit) ( S2) When it is determined that the special game is not being executed, the time for expanding the lower first type start winning port 11 is longer than usual, that is, the privilege game is being executed and the RAM ( The number of hit determination information stored and stored in the storage means 73, that is, the number of change-holding spheres is a specific number (here, 3 except for the currently changing special symbol) It is confirmed whether or not it is four or more including those) (S3).
[0059]
When it is determined in S3 that the bonus game is being executed and the number of the variation holding balls is 3 or more, it is confirmed whether or not the firing motor F2 of the launching means F is rotating slowly (S4). If the rotation is slow, the process returns. If not, the firing motor slow rotation flag B1 is set to 1 (S5). On the other hand, if the condition of S3 is not satisfied, it is confirmed whether or not the firing motor F2 of the launching means F is in slow rotation (S6), and if it is in slow rotation, the firing motor slow rotation flag B1 is set to 0. Reset (S7), return if not in slow rotation. Also, when it is determined in S2 that the special game is being executed, the firing motor slow rotation flag B1 is reset to 0 (S7).
[0060]
In the sub motor control process (S10), the rotation process of the firing motor F2 of the firing means F is actually performed based on the main motor control process (S1). In this sub motor control process (S10), as can be understood from the flowchart of FIG. 7, first, it is confirmed whether or not the launch motor slow rotation flag B1 is 1 (S11). Then, a slow rotation process is performed in which the firing motor F2 is rotated at a lower rotation speed than normal (70 rotations per minute in this example) (S12). On the other hand, if the firing motor slow rotation flag B1 is 0 instead of 1, normal rotation processing for rotating the firing motor F2 at a normal rotation speed (100 times per minute in this example) is performed (S13).
[0061]
Also, in this gaming machine 1, when a game ball passes through the normal symbol variation start gates 19 and 21, a random number value of a normal symbol per-determination counter in the main control circuit 70 is acquired, and then the acquisition After the numerical values are stored in the obtained random number storage area of the RAM of the main control circuit 70, the normal symbol hit / no-go determination process, the normal symbol display process, and the start winning opening releasing process (S20) are executed. When the gaming machine 1 is turned on, the normal symbol per-determination counter starts from “0” and is incremented by 1 every predetermined interruption time (for example, 4.000 msec), and the numerical value reaches “9”. Then, it returns to “0” again to repeat the addition. Further, the normal symbols corresponding to the respective numerical values are pre-assigned to the numerical values of the normal symbol per-determination counter. In this embodiment, when the numerical value is “0”, the normal symbol to be displayed on the normal symbol display unit 45 is “0”. Assigned as.
[0062]
In the normal symbol hit / no-go determination process, a normal symbol hit / no-win determination process for the opening of the lower first type start winning port 11 is also performed. In the normal symbol hit / no-go determination process, the acquired value of the normal symbol per-determination counter is an odd number of any one of “1”, “3”, “5”, “7”, and “9”, which is a value per normal symbol. If the acquired numerical value is an odd number, it is per ordinary symbol, and the per symbol symbol C1 is set to 1. If the obtained numerical value is an even number of any one of “0”, “2”, “4”, “6”, “8”, it is out of order and the normal symbol flag C1 is set to zero. The determination as to whether or not the normal symbol is hit is instantaneously performed at the time of starting the normal symbol variation display in the normal symbol display unit 45. In addition, in the normal symbol hit / no-go determination process, the normal symbol predetermined for the obtained value of the normal symbol hit determination counter is displayed on the normal symbol display unit 45 as a stop display symbol (normal symbol hit / no-go determination). (Indication result of processing) is instructed to be displayed.
[0063]
In the normal symbol display process, first, it is confirmed whether or not there is a normal symbol display instruction in the normal symbol hit / no-go determination process. If there is such an instruction, the normal symbol display unit 45 is displaying the normal symbol variation display. After confirming that the bonus game execution flag D1 is set to 1, that is, whether or not the bonus game is being executed (determination opportunity increasing, symbol variation time shortening, probability changing), the bonus game is determined. If it is being executed, after the normal symbol display unit 45 variably displays the reduced symbol display time (for example, about 5.9 seconds), the normal symbol is displayed on the basis of the normal symbol display instruction in the normal symbol per unit determination process. The symbol is displayed as a final stop. On the other hand, when it is determined that the bonus game is not being executed, the normal symbol display unit 45 variably displays a normal symbol for a normal variable display time (for example, about 11.8 seconds), and then whether or not the normal symbol is determined. Based on the normal symbol display instruction of the determination process, the normal symbol is finally stopped and displayed on the normal symbol display unit 45.
[0064]
In the start winning opening opening process (S20), as shown in FIG. 8, it is first determined whether or not the normal symbol hit is established, that is, whether or not the value of the normal symbol hit flag C1 is 1 (S21). ) If the two values match, after confirming that the normal symbol on the normal symbol display unit 45 is stopped (S22), and confirming that the lower first type start winning opening 11 is not currently open (S23) ), The lower first type start winning opening 11 is expanded and opened (S24).
[0065]
Thereafter, it is determined whether or not the value of the privilege game execution flag D1 is 1 (S25). When the value of the flag D1 is 1, that is, when it is determined that the current privilege game is being performed, the lower first type Whether the start winning opening 11 has been expanded and released three times for 1.7 seconds (S26), or whether the number of balls entering the first type starting winning openings 10, 11 reaches 6 (S27) Is established, the opening and closing of the lower first type start winning opening 11 is ended (closed) (S28), the value of the normal symbol per flag C1 is reset to 0 (S29), and the start The winning opening opening process (S20) is terminated. On the other hand, when it is determined in S25 that the value of the privilege game execution flag D1 is not 1, that is, when it is determined that the normal game state is being established, the time for expanding and releasing the lower first type start winning opening 11 is set. When the condition of either 0.3 second has elapsed (S30) or the number of balls entering the first type start winning ports 10, 11 reaches 6 (S27), the lower side The opening and closing of the first start winning opening 11 is ended (closed) (S28), the value of the normal symbol per flag C1 is reset to 0 (S29), and the starting winning opening opening process (S20) is ended. . Here, when the lower first type start winning opening 11 is closed, the left and right movable pieces 11a and 11b are in a substantially vertical state, so that the game ball is difficult to enter or cannot enter, but is expanded. When opened, the left and right movable pieces 11a and 11b are in a substantially V-shaped (reverse C-shaped) state, making it easier for a game ball to enter.
[0066]
In addition, this invention is not limited to the said Example, A part of structure can be changed suitably and implemented in the range which does not deviate from the meaning of invention. In the above embodiment, when the bonus game is being executed and the number of hit determination information accumulated and stored in the RAM (storage means) 73 of the main control circuit 70 is greater than or equal to a specific number, The number of shot balls is automatically reduced. However, the present invention is not limited to this. For example, the number of shot balls per unit time may be automatically reduced during the execution of a bonus game. good.
[0067]
In the above embodiment, the number of fired balls per unit time (rotation speed of the launch motor) is controlled in two stages. However, the number of fired balls per unit time is not limited to this. May be controlled in three or more stages. For example, in the normal gaming state, the launch motor is rotated fastest to maximize the number of balls to be fired per unit time, and the hits stored in the RAM (storage means) 73 of the main control circuit 70 during the bonus game are being stored. When the number of pieces of determination information is less than a specific number (for example, three), the firing motor is rotated at a medium speed so that the number of shot balls per unit time is medium. If the number is more than the specific number, the number of shot balls per unit time is minimized by rotating the launch motor the slowest.
[0068]
Furthermore, in the above-described embodiment, the lower first type start winning opening 11 is in the first state where the game balls launched into the game area 6 are difficult or impossible to enter (the movable pieces 11a and 11b are substantially vertical). ) And the second state in which the game ball is easy to enter (the movable pieces 11a and 11b are in a substantially V-shaped open / open state), and when the bonus game is being executed, Although the time of the said 2nd state of the lower 1st type start winning opening 11 is lengthened, and the occurrence frequency of this 2nd state is increased, the chance of a success / failure determination is increased, but it is not limited to this. For example, the chance of determining the success / failure during execution of the bonus game is increased by either increasing the time of the second state of the lower first type start winning opening 11 or increasing the occurrence frequency of the second state. Anyway.
[0069]
In addition, the lower first type start winning opening 11 is opened and opened in a first state in which the game ball is difficult or impossible to enter, and in which the game ball is easier to enter than the first state. There are three states such as two states and a third state in which game balls are easier to enter than the second state (for example, a state in which the degree of expansion of the movable pieces 11a and 11b is larger than the second state). It is possible to change to the above state, and only when the privilege game is being executed, the lower first type start winning port 11 may be in a state other than the first and second states, for example, the third state. In this way, the chances of determining whether or not the bonus game is being executed may be increased.
[0070]
Furthermore, in the above-described embodiment, the privilege of the privilege game is three of the determination opportunity increase, the determination result display time reduction, and the probability variation, but is not limited thereto, and includes even the determination opportunity increase as the privilege game privilege. It should be. For example, only the determination opportunity increase, the determination opportunity increase and the determination result display time may be shortened, or the determination opportunity increase and the probability fluctuation may be combined, or these may be combined with other benefits, and further the determination opportunity increase. The determination result display time reduction, probability variation, and other benefits may be combined.
[0071]
In addition, in the above embodiment, the description has been given using the pachinko gaming machine, but the present invention is not limited to this, and any suitable gaming machine of the type having a game ball launching means may be applied. it can.
[0072]
【The invention's effect】
As shown and described above, the gaming machine according to the present invention has a firing ball number reducing means for reducing the number of shot balls fired by the launching means per unit time, thereby increasing the chance of determination of success / failure. Since the number of fired balls per unit time is automatically reduced by the number-of-fired ball number reducing means during execution of the award game, as compared with the normal time, the hit / miss determination information by the storage means during the execution of the privilege game. In other words, there is no need to perform cumbersome manual work such as stopping and hitting more than the number of memories that can be stored, that is, more than the number of memories that can be stored in the starting winning opening, which is a condition for starting a hit determination. Can be reduced regardless of the player's intuition and skill, which is extremely advantageous for the player.
[0073]
Further, as in the invention of claim 2, when the bonus game is being executed and the number of hit determination information stored by the storage means is equal to or greater than a specific number, the number of shot balls per unit time If the number is automatically reduced, it is possible to reduce the number of wasted balls during the execution of the privilege game more efficiently.
[0074]
Furthermore, as in the inventions of claims 3 and 4, the start winning opening can be changed between a state in which a game ball is difficult to enter or cannot enter and a state in which a game ball is easy to enter. If the opportunity for determination of success / failure is increased by changing the start winning opening to a state where it is easy to enter the game ball during execution, the opportunity for determination of success / failure can be increased with a simple configuration. Furthermore, as in the invention of claim 5, the chances of success / failure determination are increased by performing the determination of success / failure multiple times for a single entry to the start winning opening during the bonus game. If this is the case, the chances of the success / failure determination can be increased with a simple configuration, and a novel gaming sensation that has not been possible in the past can be made to taste.
