2. Description of the Related Art As is well known, a first-class pachinko gaming machine, which is a so-called "fever machine", has numbers, symbols, figures, characters, etc. (generally called symbols) on a game board. A color liquid crystal display or a CRT (variably referred to as a variable display device) for variable display is provided, and when a game ball shot by a player's operation enters a starting winning opening, the variable display device is changed. Normally, the variable display device fluidly displays three rows of symbols from top to bottom or right to left, and then two rows out of three rows are stopped substantially at the same time, and these two stops. When the symbols do not have a predetermined specific relationship with each other (usually, the same symbols such as "7" and "7" or "○" and "○"),
It becomes a loss, and stops the fluctuation of the variable display device by immediately stopping the symbols in the remaining one row, while the two stop symbols have a specific relationship, a big hit (special game state)
In order to bring to the player the expectation that a reach state that can be said to be a warning to occur will develop from this reach state to a big hit, after changing the remaining one row of symbols for a relatively long time and then stopping , This stop symbol also has a specific relationship with the above two stop symbols (usually the same symbol such as "7", "7" and "7" or "○", "○" and "○"). If you do not play, you will lose, on the other hand, if you have a specific relationship, a big hit (special game state) occurs. When a big hit occurs, the opening / closing door of the variable winning device (big winning opening) is opened, and the opening / closing door is closed when a predetermined number (eg, 10) of game balls enter the variable winning device in the open state or when a predetermined time elapses. Then, the first round ends, and then, usually, the second round, the third round, the fourth round, ... Continue, and when the final round (for example, the fifteenth round) ends, the jackpot ends. At the time of this big hit, a lot of game balls come into the variable winning device in the open state, so a prize ball for entering the variable winning device (for example, one prize ball has 13 prize balls). A large number of pieces) are paid out to the ball saucer at the lower front of the pachinko gaming machine, so that the player can enjoy the privilege.

[0003]

However, in the pachinko gaming machine as described above, the opportunity to give a privilege to the player is that the gaming ball enters the starting winning opening and the variable display device is a jackpot pattern. It is to stop, so to speak, it is just a uniform and standard momentum, so the player asks whether the game ball enters the starting winning opening and whether the variable display device stops with a jackpot pattern. There is a problem that the game is monotonous because it concentrates only on, and it is not possible to play with fun.

The present invention solves the problems of the conventional pachinko gaming machines as described above, and in addition to the conventional uniform and standard triggers, the privilege is also granted by a sudden trigger. By doing so, it is an object of the present invention to provide a pachinko gaming machine in which the player can always play with amusement.

[0005]

The pachinko gaming machine of the present invention acquires a random number when a game ball enters the starting winning opening and causes the variable display device to start variable display, and the acquired random number has a predetermined value. When there is, the variable display device variably displays a predetermined symbol and then displays a jackpot symbol, and then, in a pachinko gaming machine that gives a bonus to the player, a ball for the player to detect a game ball. The sphere detector is provided as a detector that is invisible or difficult to see, and a random number is acquired based on the sphere detection signal of the sphere detector, and when the acquired random number is a predetermined value, the player has a privilege. Is added.

The ball detector is a launch detector that detects a game ball launched into the game area of the game board.

The ball detector is a passage detector for detecting a game ball passing through the warp route in the center of the game board.

In the random number acquisition based on the sphere detection signal of the sphere detector, the number of reserved spheres due to winning at the starting winning opening is 0.
Only when

The random number acquisition based on the sphere detection signal of the sphere detector is a period after completion of the big hit based on the winning of the starting winning opening until a predetermined number of times of random number acquisition based on the winning of the starting winning opening. Only do.

[0010] A privilege based on winning at the starting winning opening,
A difference is provided with the privilege based on the sphere detection signal of the sphere detector.

When the random number obtained based on the sphere detection signal of the sphere detector has a predetermined value, the variable display device immediately displays a big hit demonstration.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the front of a pachinko gaming machine according to one embodiment. This pachinko gaming machine has parts, devices, etc. not shown in the following description, but when the player operates the operation handle 1 of the electric launcher, the game ball 1 is placed on the launch rail from the upper ball saucer 2. The balls are sent at a predetermined time interval, and the game balls on the launch rail are hit with a hammer and launched. The launched game ball is guided by the guide rail 3 and is discharged into the game area 4 of the game board. The game balls released into the game area 4 hit the windmill 5 and the nails 6 and drop in a complicated motion, and most of the game balls do not enter any of the winning openings 8 and 9 and come out of the outlet 7. Although a few game balls are discharged to the outside of the machine, they enter the normal winning opening 8 or the starting winning opening 9.

When a game ball enters the normal winning opening 8, a normal winning detector 10 inputs a normal winning detection signal to the main board arithmetic processing circuit 60 (FIG. 2), and a predetermined number (For example, 5) prize balls are paid out to the upper ball tray 2 by the prize ball payout device.

When a game ball enters the starting winning opening 9, a starting winning detection signal is input from the starting winning detector 20 to the arithmetic processing circuit 60, and a predetermined number (predetermined number) similar to the above. For example, five prize balls are paid out to the upper ball tray 2 by the prize ball payout device, and the variable display device 30 located at the center of the game board starts to change. The variable display device 30 includes three rows of variable display units 31, 32,
33, these variable display portions 31, 32, 33 fluidly variably display the symbols in the three rows from top to bottom,
After that, the symbols in the left column 31 and the right column 33 are stopped substantially simultaneously from the three columns, and when these two stopped symbols are not the same symbol (for example, in the case of the symbols other than "7" and "7"), It becomes a loss, and the variable display is stopped by immediately stopping the symbol in the middle row 32, while the stop symbols in the left column 31 and the right column 33 are the same symbol (for example, in the case of "7" and "7"). Comes with a reach condition that can be called a big hit announcement.

After the reach state is established, only the symbols in the middle row 32 are variably displayed for a relatively long time and then stopped.
When the fluctuation of the middle row design is stopped, if the stop design of the middle row design is not the same as the stop design of the right row design and the left row design, it will be lost. On the other hand, in the case of the same symbol (for example, in the case of "7", "7" and "7"), a big hit (special game state)
Occurs. When a big hit occurs, the opening / closing door 51 of the variable winning device (big winning opening) 50 is opened, and when a predetermined number (eg, 10) of game balls enter the big winning opening 50 in the open state, or a predetermined time elapses, The door 51 is closed and the first round ends. After that, normally, the second round, the third round, the fourth round, ... Continue, and when the final round (for example, the fifteenth round) ends, the big hit ends. At the time of this big hit, if the open / close door 51 is in the closed state, the game ball that is an out ball will be guided to the special winning opening 50 by the open / close door 51, so that a large number of game balls will be a big prize. You will enter the mouth 50. Therefore, the prize balls (for example, one prize ball is thirteen prize balls) paid out for winning the prize in the special winning opening 50 are filled with the upper ball saucer 2 (the upper ball saucer 2 is full). Then, a large number of coins are paid out to the lower ball saucer 12), so that the player enjoys an advantageous privilege. In addition, on the upper part of the variable display device 30, a reserved ball number display unit 34 that displays the number of game balls that have entered the start winning opening 9 during variable display of the variable display device 30 (including during big hit operation) is provided. Has been.

The pachinko gaming machine according to the present embodiment is configured so that, in addition to the conventional standardized and standard privilege as described above, a sudden privilege can be given.

In order to give this sudden benefit, the game board is provided with a ball detector 40 which is invisible or difficult for the player to see as a ball detector. An example of the sphere detector 40 is composed of a launch detector as shown in FIGS. The launch detector 40 is configured such that the launch ball launched by the launch device is from the guide rail 3 to the game area 4
It detects that it has entered the inside, and is provided at the exit of the guide rail 3. Launch detector 40 shown in FIGS. 1 and 7.
Is a case where the movable piece 11 provided at the exit of the guide rail 3 is used, and when the launch ball pushes up the movable piece 11 and enters the game area 4, the movable piece 11 prevents the player from visually recognizing the case. The micro switch 41 covered with 42 is turned on, and the sphere detection signal is input from the micro switch 41 to the arithmetic processing circuit 60. Note that the launch detector 40 is not limited to such a configuration, and may be any as long as it can detect passage of the launch ball as an electric signal regardless of whether it is in contact with the launch ball or not.

Then, based on such a ball detection signal of the launch detector 40, a sudden benefit is given to the player, and the specific contents of this sudden benefit will be described later.

FIG. 2 shows a basic block diagram of a pachinko gaming machine as described above. In FIG. 2, an arithmetic processing circuit 60 composed of a main board and a symbol control board is connected to the starting prize detector 20 and the launch detector 40, and is also connected to the variable display device 30 and the variable prize device 50.

The arithmetic processing circuit 60 is used for the starting winning prize detector 20.
When a start winning detection signal is input from the main random number generating means (corresponding to the conventional random number generating means) 61, a random number (also referred to as a main random number in the sense of the same random number as the conventional random number) is acquired, and the main game state determining means ( Based on the main random number acquired by 62) (corresponding to the conventional game state determining means), whether to generate a reach, a big hit, or a reach in the case of a loss, the time when the reach state is established (the time when the reach display is started in the variable display device 30) ) To a variable time from the change stop, what to do with the big hit symbol and the lost symbol, various game states (also called the main game state in the sense of the same gaming state as the previous gaming state) are determined. Then, based on the determined main game state, the display control means 63 controls the display of the variable display device 30, and the opening / closing control means 64 controls opening / closing of the opening / closing door 51 of the variable winning device 50. The arithmetic processing by the arithmetic processing circuit 60 is also performed in the conventional pachinko gaming machine.

The arithmetic processing circuit 60 according to this embodiment is characterized by including a sub-random number generating means 65 and a sub-game state determining means 66. The sub-random number generating means 65 is the emission detector 4
When a sphere detection signal is input from 0, a random number (also called a sub random number in the sense of a random number different from the previous random number) is acquired, and the sub game state determination means 66 determines whether the game is a big hit or a big hit based on the acquired sub random number. A game state (also called a sub game state in the sense of a game state different from the previous game state) is determined. Then, in the case of a big hit, that is, when the acquired sub-random number is a predetermined value, the display control unit 63 causes the variable display device 3
0 is given a jackpot demo display, and then a round display is made for each round. In addition, the opening / closing control means 64 controls the opening / closing door 5 of the variable winning device 50 at the same time when the jackpot demonstration display ends.
Release 1 to start the first round. When a predetermined number of game balls are won in the variable winning device 50 in the first round, the opening / closing door 51 is once closed, and then the second round is started. After that, the opening / closing door 51 is similarly opened and closed for a predetermined round, for example, the fifteenth round. The jackpot ends in a round. On the other hand, in the case of loss, display control means 63 and opening / closing control means 64
Has no special control.

Here, the probability (big hit occurrence rate) that the random number (sub-random number) obtained based on the ball detection signal of the launch detector 40 becomes a predetermined value is set to, for example, 1/10000, while the start winning opening The probability (big hit occurrence rate) that the random number (main random number) acquired based on the ball entry of is a predetermined value is, for example, 1 /
The probability that the sub-random number has a predetermined value is set to be sufficiently lower than the probability that the main random number has a predetermined value.

The sub-random number acquisition may be performed only under a predetermined condition. For example, it is performed only when the number of reserved balls due to winning at the starting winning opening 9 is 0, or after the jackpot based on the winning at the starting winning opening 9 is finished, a main random number based on winning at the starting winning opening 9 The acquisition is performed only during a period until the acquisition is performed a predetermined number of times (for example, 100 times).

The acquisition of the sub-random number may be performed each time one game ball is detected by the launch detector 40, or a plurality of (for example, 10) game balls are detected by the launch detector 40. It may be performed each time it is detected.

Further, a difference may be provided between the privilege based on the winning at the start winning port 9 and the privilege based on the ball detection signal of the launch detector 40. For example, the former privilege may be a privilege with 15 rounds and the latter privilege may be with 10 rounds, or the former privilege may be a privilege with probability variation and the latter privilege may be a privilege without probability variation. Good.

Further, when the random number acquired based on the ball detection signal of the launch detector 40 is a predetermined value within the period in which the privilege based on the winning in the starting winning opening 9 is given, it is based on the ball detection signal. The privilege may not be given. Further, the privilege based on the ball detection signal may be given subsequently to the privilege based on the winning in the starting winning opening 9.

FIG. 3 shows the arithmetic processing circuit 60 as described above.
4 is a flowchart showing an example of a calculation process by In FIG. 3, the arithmetic processing circuit 60 includes a start winning detection device 20.
Whether or not there is a start winning is determined based on the signal from (S
It is determined whether or not the game ball has been launched into the game area 4 based on the signal from the launch detector 40 together with 1) (S).
2).

If there is a start winning, the main random number is acquired (S
3) It is determined from the obtained main random number whether or not it is a big hit (S4). Here, the jackpot occurrence rate is, for example, 1/350
Is set to. In the case of losing, the variable display device 30 is caused to perform the losing operation (S5). On the other hand, in the case of a big hit,
With respect to the variable display device 30, the left and right column symbols are stopped to generate a reach state (S6), then the middle column symbol, which is a jackpot symbol, is stopped (S7), and subsequently a jackpot demonstration display is made (S8). , The variable winning device 50 is opened and closed (S9). The number of rounds for this jackpot is set to 15 times, for example, and the probability is changed.

On the other hand, when a game ball is fired, a sub-random number is acquired (S10), and it is determined from the acquired sub-random number whether or not it is a big hit (S11). In the case of a loss, the process returns to the start winning determination step S1. On the other hand, in the case of a big hit, the big display demonstration is immediately displayed on the variable display device 30 (S12),
Open and close the variable winning device 50 (S1
3). Here, the jackpot occurrence rate is, for example, 1/10000.
Is set to. Also, the number of rounds of this big hit may be set to 15 times as well as the big hit due to the starting prize, and may be set so that there is a probability variation, but unlike the big hit due to the starting prize, the number of rounds is, for example, 10 times. It may be set so that there is no probability change as well.

In the flow chart of FIG. 3, when a big hit occurs due to a start winning, the big hit is not judged by the launch of the game ball during the big hit operation, that is, the privilege by the launch of the game ball is not given. It may be possible to determine a big hit by launching a game ball during a big hit operation by winning, and in the case of a big hit, a benefit by launching a game ball may be given subsequently to a benefit by a starting winning prize.

FIGS. 4, 5 and 6 each show a replacement portion obtained by replacing a part of the flowchart of FIG.

In FIG. 4, the determination step S2 (see FIG.
Is the same as the determination step S2), the number of shot balls is counted every time the game ball is shot is determined (S
14) When the number of shot balls reaches a predetermined number, for example, 10 (S1
5) After clearing the number of shot balls counted (S1
6), the sub-random number is acquired (S10 (step S1 in FIG. 3).
It is the same as 0)).

In FIG. 5, when the determination step S2 determines "there is a game ball being fired", it is determined "whether the number of reserved balls is 0" (S17), and only when the number of reserved balls is 0 A random number is acquired (S10).

In FIG. 6, when the determination step S2 determines that "there is a game ball fired", "whether or not the number of starting prizes after the jackpot motion due to the starting prize is 100 or less"
Is determined (S18), and the sub-random number is acquired only when "YES" (S10).

FIG. 8 shows another example of the sphere detector 40. In FIG. 8, around the screen 35 of the variable display device 30,
A well-known warp route 70 is provided. The warp route 70 has a game ball entrance 71 on the upper front side of the screen 35.
In addition, the passage 7 is not visible to the player on the left and right sides.
It has 2, 73. The game ball that has entered the entrance 71 of the warp route 70 is distributed to either the left or right passage 72 or 73, and is discharged from the exit 74 or 75 of the passage 72 or 73 onto the stage 76 on the lower front side of the screen 35.
The game ball discharged onto the stage 76 is the starting winning opening 9
(See FIG. 1) The ball comes to fall from just above (see FIG. 1), and it is easy to enter the starting winning opening 9. The left and right passages 72, 73 are provided with passage detectors 40, 40 for detecting the game balls passing through the passages 72, 73, respectively. The passage detectors 40, 40 electrically detect the passage of the game ball. The sphere detection signal of each passage detector 40 is input to the arithmetic processing circuit 60, and the arithmetic processing circuit 60 performs the same arithmetic processing as the above-described arithmetic processing when the sphere detector is the launch detector 40. Be seen. Here, in the arithmetic processing circuit 60, either the left or right passage detector 40
The big hit occurrence rate based on the sphere detection signal and the big hit occurrence rate based on the sphere detection signal of the other passage detector 40 are set to be the same or different. When the big hit occurrence rates are different, for example, the big hit occurrence rate for one passage detector 40 is set to 1/500, and the big hit occurrence rate for the other passage detector 40 is set to 1/1000. The passage detector 40 may be provided in only one of the left and right passages 72 and 73.

As described above, the pachinko gaming machine according to the present embodiment acquires a random number when the game ball enters the starting winning opening 9 and causes the variable display device 30 to start the variable display. When the value is a predetermined value, the variable display device 30 variably displays a predetermined symbol and then displays a jackpot symbol, and then, in a pachinko gaming machine that gives a bonus to the player, detects a game ball for the player. As a sphere detector for use, the sphere detector 40 is provided in an invisible or difficult state, and a random number is acquired based on the sphere detection signal of the sphere detector 40. When the acquired random number is a predetermined value, the player I'm going to give benefits to. For this reason, it is uniform that the bonus is given by starting from the conventional start winning hole 9 and stopping at the jackpot pattern.
Unlike the regular trigger of the privilege, the bonus will be granted by the unexpected trigger that the player cannot recognize,
Players will be able to play games with interest.

Here, the probability that the random number obtained based on the sphere detection signal of the sphere detector 40 will be a predetermined value is the starting winning opening 9
By setting it sufficiently low compared to the probability that the random number obtained based on the entry to the ball will be a predetermined value, the jackpot occurrence rate based on sudden triggers will be approximately equal to the jackpot occurrence rate based on the starting prize from the past. can do.

Further, by configuring the ball detector 40 by a launch detector that detects the game ball launched in the game area 4 of the game board, the game ball that has not been launched in the game area 4 due to a miss firing. It is possible to prevent the trouble of granting a privilege based on.

Further, by constructing the ball detector 40 by a passage detector for detecting a game ball passing through the warp route 70 in the central portion of the game board, the warp route 70 is usually provided.
Since the internal passages 72 and 73 are invisible to the player, the passage detector 40 can be provided in a state invisible to the player.

Further, the random number acquisition based on the ball detection signal of the ball detector 40 is performed only when the number of reserved balls due to winning in the starting winning opening 9 is 0, or in winning in the starting winning opening 9. After the jackpot based on the completion, the random number acquisition based on the winning at the starting winning port 9 is performed only until the predetermined number of times, so that the sudden triggers are varied and sudden to the player. It is possible to increase the unexpectedness of the privilege granting due to such a trigger.

When the random number obtained based on the sphere detection signal of the sphere detector 40 has a predetermined value, the variable display device 30
By immediately displaying the jackpot pattern, it is possible to give the player a strong impression that the bonus is a sudden trigger.

Further, when the random number obtained based on the ball detection signal of the ball detector 40 is a predetermined value within the period in which the privilege based on the winning in the starting winning port 9 is given, it is based on the ball detection signal. By not granting the privilege, or by granting the privilege based on the ball detection signal subsequently to the privilege based on the winning in the starting winning opening 9, it is possible to diversify the trigger momentarily.
