Description

[0001]
[Industrial application fields]
The present invention relates to a gaming machine that uses a game ball to play a game. For example, as represented by a pachinko machine, when a big hit occurs, a winning member is operated to form a winning opening, and the game ball is won. The present invention relates to a gaming machine that changes to an easy-to-use state.
[0002]
[Prior art]
Conventionally, for example, a pachinko machine shown in FIG. 8 is known as this type of gaming machine. FIG. 8 is a schematic explanatory view of a conventional pachinko machine viewed from the front.
When a game ball launched by operating an operation handle 501 provided in the pachinko machine 500 wins the first type starting port 502 or the ordinary electric accessory 503 with both wings open, the symbol display device 504 is displayed on the screen. A plurality of symbols (for example, 0 to 9) are scroll-displayed in the vertical direction at the three horizontal directions. Then, after a predetermined time has elapsed, the scrolling at the three places stops, and when the stopped three symbols are big hit symbols (for example, 777 as shown in FIG. 8), a big hit occurs, and the door-type opening / closing member 505 is opened. In operation, a special winning opening 506 is formed.
Then, when a game ball wins a prize winning opening 506, a predetermined number (for example, 15) of winning balls are paid out to the upper tray 508 for each winning ball. Also, either the number of winning balls won in the grand prize opening 506 reaches a specified number (for example, 10) or a predetermined time (for example, 30 seconds) has elapsed since the grand prize opening 506 opened. When these conditions are satisfied, the opening / closing member 505 is closed and the special winning opening 506 is closed. Furthermore, when the game ball that has won the big prize opening 506 passes through a specific area 507 provided inside the big prize opening 506, the right to continuously open the big prize opening 506 is generated. In this way, it is possible to play a plurality of rounds (for example, 16 rounds) on condition that a game ball passes through the specific area 507 from the opening to closing of the grand prize winning opening 506 as one round. it can.
[0003]
[Problems to be solved by the invention]
By the way, since the opening area of the grand prize winning opening 506 is much larger than that of other winning prize openings, a plurality of game balls may win the big winning prize opening 506 at the same timing. If it is a time just after the opening of the big winning opening 506, there is no problem even if a plurality of game balls win the big winning opening 506 at the same timing, but the time when the winning number is already close to the prescribed number, For example, if a plurality of game balls wins the big winning opening 506 at the same timing when the number of winnings is already “9”, the number of winnings exceeds the specified number.
That is, in the conventional pachinko machine 500, since there are variations in the number of winnings at the big winning opening 506, the number of balls in the big hit differs among players, and it is difficult to play a fair game. There is.
[0004]
Accordingly, an object of the present invention is to realize a gaming machine capable of playing a fair game by reducing the variation in the number of winnings.
[0005]
[Means, actions and effects for solving the problems]
  In order to achieve the above object, according to the first aspect of the present invention, in the invention according to claim 1, when a big hit occurs, the big winning opening is opened and the big winning opening is opened while the big winning opening is opened. An opening / closing member for closing the large winning opening when the number of winnings reaches a specified number; andThe opening / closing member that is provided above and can be changed between a form protruding above the upper surface of the opening / closing member that is opened when the special winning opening is opened and a form that does not protrude. A regulating member that regulates the winning of the game ball flowing down from above into the big prize opening by changing to a form protruding above the upper surface of the upper surface, and when the big prize opening is openUntil the number of wins to the big prize opening reaches a predetermined number less than the prescribed number,Maintain the configuration in which the regulating member does not protrude above the upper surface of the opening / closing member that has been opened.And when the number of winnings reaches the predetermined number,The restriction member protrudes above the upper surface of the opening / closing member that has been opened.And a technical means that includes a control means.
[0020]
  That meansMaintain the form that does not protrude above the upper surface of the opening and closing member that opened the restricting member until the number of winning a prize winning opening reaches a predetermined number less than the prescribed number when the big winning opening is open, and When the number of winnings reaches a predetermined number, the number of winnings can be adjusted from the upper direction of the large winning opening by projecting above the upper surface of the opening / closing member that has opened the regulating member. Reduce variation ofcan do.
  Therefore, a pachinko machine capable of playing a fair game can be realized.
  For example, as described in a second embodiment to be described later, when a restricting member 47 (adjustment member) is provided on the top of the big winning opening 46 and the prescribed number of winning numbers of the big winning opening 46 is “10”, By opening the restricting member 47 when the number of winnings is “7”, the flow direction of the game ball flowing down to the big prize opening 46 is changed, so that one of the game balls rolling down from the restricting member 47 Since only the teams will win the big winning opening 46, the number of winnings can be set to the prescribed number “10” or a number close to the prescribed number (“9” or “11”).

[0037]
[Main game flow]
Next, the main flow of the game will be described with reference to FIG.
FIG. 6 is a flowchart showing the flow of round control executed by the main CPU 112 for controlling the round progress at the time of big hit.
When the game ball wins the first type starting port 14 (FIG. 2) or the opened ordinary electric accessory 27 and the first type starting port switch 14a (FIG. 5) is turned ON, the main CPU 112 determines whether or not it is a big hit. In the case of a big hit, a big hit symbol is determined, and in the case of a loss, a lost symbol is determined. At this time, the main CPU 112 sets a big hit flag when it is judged as big hit. Then, the main CPU 112 transmits a command for instructing the special symbol control device 32 to display the variation pattern of the special symbol and the display of the fixed symbol. The special symbol control device 32 follows the received command in three places in the horizontal direction of the screen. , A plurality of special symbols (for example, “0” to “9”) are scroll-displayed in the vertical direction. Then, when a predetermined time has elapsed, the scrolling is stopped, and special symbols are fixedly displayed at the three locations. When the three special symbols that are confirmed and displayed are jackpot symbols (for example, “777”), an effect of generating a jackpot by sound and LED is performed.
[0038]
The main CPU 112 determines whether or not the big hit flag is set (step (hereinafter abbreviated as S) 10), and if it is determined that it is set (S10: Yes), “1” is added to the round number R. (S12), a signal for turning on the winning prize solenoid 46b (FIG. 5) is output to the winning prize solenoid 46b (S14). As a result, the special prize opening solenoid 46b is turned ON, and the opening / closing member 41 is opened to open the special prize opening 46 (FIG. 3B). Subsequently, the main CPU 112 outputs a signal for turning on the guide member solenoid 42c to the guide member solenoid 42c (FIG. 5) (S16). Thereby, the guide member solenoid 42c is turned ON, and the guide members 42 and 43 are closed (FIG. 3B). In this way, the first round starts.
[0039]
The game ball that has flowed down from above the opening / closing member 41 that has been opened and has won the big prize opening 46 is received by the upper surface 41d of the plate-like part 41a, guided to the opening 44, and the big prize opening switch 46a (FIG. 4). ) Is detected. Further, the game ball that has flowed down from above the guide member 42 and received by the upper surface 42b of the guide member 42 is guided to the upper surface 41d of the opening / closing member 41 that has been opened, and is guided to the opening 44, so that the big prize opening switch 46a. Further, a part of the game ball received by the upper surface 42b falls from the gap 48 and is recovered as an out ball from the out port 17 (FIG. 2) without being detected by the big winning port switch 46a.
The game ball that has flowed down from above the guide member 43 and received by the upper surface 43b of the guide member 43 is guided to the upper surface 41d of the opening / closing member 41 that has been opened, guided to the opening 44, and by the big prize opening switch 46a. Detected. Further, a part of the game ball received by the upper surface 43b spills out from the gap 49 and is recovered as an out ball from the out port 17 (FIG. 2) without being detected by the big winning port switch 46a.
[0040]
Subsequently, the main CPU 112 starts measuring a prize winning opening time (for example, 29.5 seconds), which is the maximum time during which the opening and closing member 41 is opened (S18), and determines that the measurement time has timed up. Then (S20: Yes), a signal for turning off the special winning opening solenoid 46b is output to the special winning opening solenoid 46b (S28). As a result, the special winning opening solenoid 46b is turned OFF, the opening / closing member 41 is closed, and the special winning opening 46 is closed.
Further, until the time is up (S20: No), the main CPU 112 takes in the switching signal from the big prize opening switch 46a (FIGS. 4 and 5), counts the number N of winning prizes to the big prize opening 46, and wins the prize. It is determined whether or not the number N has reached “7” (S22). If it is determined that the number N has reached (S22: Yes), a signal for turning off the guide member solenoid 42c is output to the guide member solenoid 42c (S24). As a result, the guiding members 42 and 43 do not perform the function of guiding the game ball to the opening / closing member 41, so that only the game ball flowing down directly above the opening / closing member 41 wins the big winning opening 46. .
In other words, the number of game balls detected per unit time is reduced by the special winning opening switch 46a.
[0041]
By the way, the numerical value “7” which is the determination criterion of S22 is that the game ball is not guided by the guide members 42 and 43 after the winning number N reaches “7”, and the opening / closing member 41 alone is used to enter the big winning port 46. It is a numerical value set so that the measurement time is increased when the number of winning game balls is three and the winning number N reaches the prescribed number “10”. Also, immediately before the opening / closing member 41 is closed, there may be a plurality of game balls in the flow path 44a (FIG. 4), the opening 44, and the upper surface 41d (FIG. 3). The number of such game balls is also included in the above-mentioned three since it is detected by the big prize opening switch 46a after the 41 is closed.
[0042]
Subsequently, the main CPU 112 determines whether or not the winning number N has reached the prescribed number “10” (S26). If the main CPU 112 determines that the winning number N has been reached (S26: Yes), the main CPU 112 outputs a signal for turning off the big winning port solenoid 46b. An output is made to the special winning opening solenoid 46b, and the opening / closing member 41 is closed (S28). Subsequently, the main CPU 112 outputs a signal for turning off the guide member solenoid 42c to the guide member solenoid 42c to open the guide members 42 and 43 (S30). This S30 is a step for opening the guiding members 42 and 43 after the end of the round even if the winning number N does not reach “7” during the first round.
Subsequently, the main CPU 112 determines whether or not the round number R calculated in S12 has reached the maximum of 16 rounds (16 rounds is an example) (S32), and if not (S32: No) Then, it is determined whether or not the specific area switch 45a (FIG. 5) is turned on (S34). That is, it is determined whether or not the game ball that has won the big prize opening 46 has passed a specific area provided inside the big prize opening 46. If it is determined that the specific area switch 45a is turned on (S34: Yes), the next second round is executed (S12 to S34).
[0043]
If the main CPU 112 determines that 16 rounds have been executed in S32 (S32: Yes), or if it is determined in S34 that the specific area switch 45a is not ON (S34: No), the number of rounds R and The winning number N is reset to 0 (S36), the big hit flag is reset (S38), and the current routine of the round control is terminated.
The round control is executed by a computer program recorded in the ROM 114.
[0044]
[Effect of the first embodiment]
(1) As described above, if the pachinko machine 1 according to the first embodiment is used, the main CPU 112 controls the opening and closing of the guide members 42 and 43, thereby changing the flow direction of the game ball and winning the winning prize port 46. Since the number N of winning prizes can be adjusted, the variation in the number N of winning prizes can be reduced.
Therefore, a pachinko machine capable of playing a fair game can be realized.
(2) In particular, the guide members 42 and 43 are closed until the winning number N reaches “7” to promote winning to the big winning opening 46, and after the winning number N reaches “7”. By making the opening operation not to promote the winning, the number of winnings in one round can be made to be a substantially prescribed number.
(3) In addition, in the winning path formed between the guide members 42 and 43 and the opening and closing member 41, gaps 48 and 49 are formed, and a part of the game ball guided by the guide members 42 and 43 Spills out of the gaps 48 and 49, so that the increase in the number of winnings in a short time can be adjusted.
(4) Furthermore, since the guide members 42 and 43 are provided in both lateral directions of the opening / closing member 41, the number of winnings from both lateral directions of the opening / closing member 41 can be adjusted.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG.
FIG. 7A is a perspective explanatory view showing a state in which the variable winning device 40 and the regulating member 47 are closed, and FIG. 7B is an illustration in which the variable winning device 40 is opened, and the regulating member FIG. 7C is a perspective explanatory view showing a state where the variable winning device 40 and the regulating member 47 are opened. Note that the pachinko machine of this embodiment has the same configuration and function as the pachinko machine of the first embodiment, except for the means for adjusting the number of winnings in the big prize opening 46, and therefore the description of the same parts is omitted. Moreover, the same code | symbol is used about the same structure as 1st Embodiment.
[0046]
The restricting member 47 is provided immediately above the variable winning device 40, and changes the flow direction of the game ball flowing down toward the variable winning device 40 in the opened state, thereby winning the prize winning opening 46. Adjust the number. As shown in FIG. 7C, the regulating member 47 is formed in a mountain shape in the opened state, and a right inclined surface 47d inclined downward from the top to the lower right and a left inclined surface 47c inclined downward from the top to the lower left. And have. At the rear end of the regulating member 47, rod-shaped shaft members 47b are formed to protrude in the lateral direction, and each shaft member 47b can be rotated by an opening / closing mechanism (not shown) for opening and closing the regulating member 47. The shaft is fixed. The regulating member 47 and the opening / closing mechanism are provided in a housing (not shown) like the housing 41f (FIG. 4) of the variable prize device 40, and the regulating member 47 is provided in the housing via the opening / closing mechanism. There is provided a solenoid (not shown) for opening and closing. The housing is formed with an accommodating space 47e (FIG. 7C) for accommodating the regulating member 47 that is closed, and when the regulating member 47 is accommodated in the accommodating space 47e, the bottom surface 47a is connected to the game board 5. It becomes substantially flush (FIG. 7A). Further, when the regulating member 47 is opened, the regulating member 47 changes to a form protruding above the upper surface 41d of the opening / closing member 41 that has been opened.
[0047]
When the big hit has not occurred, as shown in FIG. 7A, the opening / closing member 41 and the regulating member 47 are both in a closed operation, and do not receive the game ball flowing down. When the big hit occurs, as shown in FIG. 7B, the opening / closing member 41 is opened, and the game ball P flowing down from above wins the big winning opening 46, and the winning game ball P Is guided to the opening 44 and detected by the big prize opening switch 46a (FIG. 4). Then, when the number N of winning prizes to the big winning opening 46 reaches “7”, the regulating member 47 is opened as shown in FIG. As a result, a part of the game ball that flows down from above toward the opening / closing member 41 collides with the right inclined surface 47d and the left inclined surface 47c of the regulating member 47, rolls down from each inclined surface, and one of the game balls that has rolled down. The part wins the big winning opening 46, and a part flows down from the side of the opening / closing member 41 without winning the big winning opening 46, and is collected as an out ball from the out opening 17.
That is, by opening the restricting member 47, the number of winning prizes of the large winning opening 46 per unit time is reduced.
[0048]
By the way, the winning number “7”, which is a determination criterion for opening the restricting member 47, is larger only by the opening / closing member 41 without being restricted by the restricting member 47 after the winning number N reaches “7”. This is a numerical value set so that the time for measuring the opening time of the big winning opening is increased when the number of game balls won in the winning opening 46 becomes three and the winning number N reaches the prescribed number “10”. Also, immediately before the opening / closing member 41 is closed, there may be a plurality of game balls in the flow path 44a (FIG. 4), the opening 44, and the upper surface 41d (FIG. 3). The number of such game balls is also included in the above-mentioned three since it is detected by the big prize opening switch 46a after the 41 is closed.
Then, when the number N of winning prizes 46 reaches “10” or when the opening time of the big prize opening times out, both the opening / closing member 41 and the regulating member 47 are closed, and the first round is completed. Thereafter, from the second round to the last round is executed under the same control as the first round.
The opening / closing operation of the opening / closing member 41 and the regulating member 47 is controlled by the main CPU 112.
[0049]
[Effects of Second Embodiment]
(1) As described above, if the pachinko machine 1 according to the second embodiment is used, the main CPU 112 controls the opening and closing of the restricting member 47, thereby changing the flow direction of the game ball to the winning prize opening 46. Since the winning number N can be adjusted, variation in the winning number N can be reduced.
Therefore, a pachinko machine capable of playing a fair game can be realized.
(2) In particular, the regulating member 47 is closed until the winning number N reaches “7” to promote the winning to the big winning opening 46, and is opened after the winning number N reaches “7”. Thus, by not promoting the winnings, the number of winnings in one round can be made a substantially prescribed number.
(3) Since the regulating member 47 is provided above the opening / closing member 41, the number of winnings from above the opening / closing member 41 can be adjusted.
