The firing control board 111 operates the launching device 110 provided corresponding to the handle 6 in response to the player operating the handle 6. According to the operation amount of the handle 6, it is possible to adjust the ball launching strength (ball flight distance).

Next, the operation of the pachinko gaming machine 1 according to the first embodiment configured as described above will be described.

After the power to the pachinko gaming machine 1 is turned on, the balls prepared in the ball supply tray 4 are guided to the guard rail 7 by the launching device 110 (see FIG. 11) including the handle 6, and the game board 3 and the transparent plate It is launched toward a dome-shaped game space formed between the two. At this time, the movable member 71 is swung by, for example, pushing the central protrusion 61 of the handle 6, and the movement trajectory of the ball in the guard rail 7 changes according to the swung position of the movable member 71. For this reason, the traveling direction of the balls passing through the guard rail 7 and discharged from the ball discharge port 7a to the game space is dispersed in a wide range from the near side to the depth side. The ball released into the game space from the front side may be directly sucked into the start winning opening 10 or the opened large winning opening 11 without hitting the nail 18 even once. Further, after the ball hits the nail 18 several times, the ball may be sucked into the start winning opening 10 or the opened large winning opening 11. That is, the ball moves while jumping freely in the three-dimensional game space, which is greatly different from the conventional movement of the ball that just flows down while hitting the nail along the two-dimensional game area. For this reason, it is possible to provoke a player with a completely different interest from the conventional pachinko gaming machine.

When a ball wins the start winning opening 10, this is detected by the start winning detector 112 and a winning detection signal is transmitted to the main circuit 120. The main circuit 120 obtains a random value (counter value) from a special drawing lottery counter (not shown) according to the timing at which the winning detection signal is input, and whether the random value matches the special figure jackpot random number. By determining whether or not, a special drawing is drawn. The special drawing lottery result is temporarily stored in the special drawing reserved ball storage area assigned to the RAM 123. In addition, the main circuit 120 confirms whether or not the symbol display unit 9 can perform a variation process of a new special figure, and then reads the special drawing lottery result and displays the special figure at the center of the symbol display unit 9. Start the fluctuation process. In addition, when the process of changing a new special figure cannot be performed (when the process of changing the special figure related to the lottery result of the previous special figure is being performed, or when the jackpot process described later is being performed) The special drawing lottery results are stored in the special drawing reserved ball storage area with an upper limit of four.

In the special figure changing process, the main circuit 120 receives the lottery result of the read special figure, determines a symbol to be displayed, and stops the special symbol display unit of the symbol display unit 9 with the determined symbol. If you stop at the jackpot symbol, you will be in a jackpot state. Note that the probability of stopping at the jackpot symbol (hit probability) is set to 1/395, for example, in the normal state, and 1/50, for example, in the probability variation state. When the jackpot symbol is stopped, the probability that the jackpot symbol is a normal jackpot symbol is set to 4/10, for example, and the probability that the jackpot symbol is a probabilistic jackpot symbol is set to 6/10, for example. When the big win state is reached, the main circuit 120 drives the big prize solenoid 115 to start a big hit process that repeats the opening / closing operation of the big prize opening 11 a predetermined number of times.

When a ball is won in the opened big winning opening 11, this is detected by the big winning detector 113, and a big winning detection signal is transmitted to the main circuit 120. The main circuit 120 pays out a predetermined number of prize balls based on the big winning detection signal, and determines whether or not the maximum number of balls (for example, ten balls) to the big winning opening 11 is detected. . Here, when the winning of the maximum number (10) of balls is detected, the main circuit 120 closes the large winning opening 11.

On the other hand, when the maximum number of winning (10) balls is not detected, the main circuit 120 determines whether or not the opening time of the large winning opening 11 has passed the maximum opening time (for example, 25 seconds). Here, when the opening time of the big winning opening 11 has passed the maximum opening time (25 seconds), the main circuit 120 closes the big winning opening 11 by deactivating the big winning solenoid 115.

In this way, one round is defined as the time when the big prize opening 11 is opened once and is closed, and the main circuit 120 opens the big prize opening 11 until the number of rounds reaches the maximum number of rounds (for example, 15). And the closing operation are repeated. When the number of rounds reaches the maximum number of rounds, the main circuit 120 ends the jackpot process. In addition, when the special figure that triggered the jackpot processing is a normal jackpot symbol, it will be in a normal state, and when it is a probabilistic jackpot symbol, it will be in a probabilistic state.

As described above, according to the first embodiment, the game area of the game board 3 has a three-dimensional structure having a depth over the entire range, thereby providing unprecedented game performance and providing this to the player. It can give an unprecedented interest.

As shown in FIG. 16, the accessory device 8 is formed in a short cylindrical shape, and a symbol display unit 9 made of a liquid crystal display device or the like is disposed at the rear open end. In addition, the symbol display unit 9 displays a general symbol display unit that displays a general symbol determined by a lottery result of a general symbol (ordinary symbol), and the number of reserved balls stored in the general symbol reserved ball storage area. A special map display unit for displaying a symbol corresponding to the symbol, a special map display unit for displaying a special map determined by a lottery result of the special map, and a reserved ball stored in the special map reserved ball storage area. And a special figure holding display section for displaying symbols corresponding to the number of

The passing gate 15 is a gate without a prize ball, and when a ball passes through the passing gate 15, a usual variation process is performed.

The winning openings 16, 17 are ordinary winning openings, and when a ball passes, a predetermined number of winning balls are paid out.

On the surface of the game board 3, a large number of nails 18 are implanted over almost the entire area of the game board 3 toward the virtual center of the game area 3 whose head is curved (the center of the sphere with the game board 3 as a surface). Has been. In this way, the nail 18 is implanted over almost the entire area of the game board 3 although the ball moves in the game area where the balls are curved, but in terms of topology, the board surface of a flat game board This is because, like the conventional pachinko gaming machine, it is possible to plant the nails 18 over almost the entire area of the game board 3.

Referring to FIG. 17, the pachinko gaming machine 1 ′ controls the main control board 100, the display control board 101 that controls the symbol display unit 9, the voice control board 103 that controls the amplifier / speaker 104, and the lamps 106.

The start prize detector 112 provided in the main prize, the big prize detector 113 provided in the big prize opening 11, the big prize solenoid 115 for opening and closing the big prize opening 11, and a power supply circuit section for supplying a predetermined voltage to each board 116, a gate passage detector 131 that detects the passage of a ball at the passage gate 15, and an electric Chuo solenoid that opens and closes a start winning opening 10 'that is an electric chew. And 132 is configured to include a prize detector 133 for detecting a winning ball in the winning openings 16,17.

The other members not particularly mentioned are configured in the same manner as the corresponding members in the pachinko gaming machine 1 according to the first embodiment shown in FIG. 1 to FIG. I will omit the detailed explanation of them.

Next, the operation of the pachinko gaming machine 1 ′ according to the second embodiment configured as described above will be briefly described focusing on differences from the case of the pachinko gaming machine 1 according to the first embodiment.

After the power to the pachinko gaming machine 1 ′ is turned on, the balls prepared in the ball supply tray 4 are launched toward the game board 3 by the launching device 110 (see FIG. 17) including the handle 6. The ball that has reached the game board 3 flows down on the board surface of the game board 3 while hitting the nail 18 along the curved game area formed by the gap between the transparent plate 2 ′ and the game board 3.

When the ball passes through the passage gate 15, the gate passage detector 131 detects this and a gate passage detection signal is transmitted to the main circuit 120. The main circuit 120 acquires a random number value (counter value) from a general drawing lottery counter (not shown) according to the timing when the gate passage detection signal is input, and the random number value matches the random number per general drawing. The lottery of the usual figure is performed by determining whether or not. The usual drawing lottery result is temporarily stored in the usual drawing reserved ball storage area allocated to the RAM 123. In addition, the main circuit 120 confirms whether or not the symbol display unit 9 can perform a new process of changing the normal map, and then reads out the lottery result of the normal map and displays it in the general map display unit of the symbol display unit 9. To start the usual fluctuation process. In addition, when it is not possible to perform the process of changing the new map (when the process of changing the map according to the lottery result of the previous map is being performed, or when the winning process described later is being performed) The usual drawing lottery results are stored in the usual drawing reserved ball storage area with the upper limit of four.

In the fluctuation process of the usual figure, the main circuit 120 determines the symbol to be displayed in response to the read lottery result of the usual figure, and stops the universal figure display unit of the symbol display unit 9 with the decided symbol. When the ordinary figure stops at the winning symbol, the winning state is reached. Note that the probability of stopping at the winning symbol (the winning probability) is always constant, and is set to 9/10, for example. When the winning state is reached, the main circuit 120 starts a winning process for opening the start winning opening 10 '.

Specifically, the main circuit 120 opens the start winning opening 10 ′ for a predetermined opening time (for example, 0.2 seconds) in a normal state where a probability variation (probability variation) state has not occurred. On the other hand, in the probability changing state, the main circuit 120 opens the start winning opening 10 'for another predetermined opening time (for example, 5 seconds). That is, by the control signal from the main circuit 120, the start winning port 10 ′ that is an electric chew is opened, the winning rate of balls to the starting winning port 10 ′ is increased, and after the opening time has elapsed, the ball is closed. The winning rate is lower than in the open state.

When a ball wins the start winning opening 10 ′, the start winning detector 112 detects this and a winning detection signal is transmitted to the main circuit 120. The main circuit 120 obtains a random value (counter value) from a special drawing lottery counter (not shown) according to the timing at which the winning detection signal is input, and whether the random value matches the special figure jackpot random number. By determining whether or not, a special drawing is drawn. The special drawing lottery result is temporarily stored in the special drawing reserved ball storage area assigned to the RAM 123. Further, the main circuit 120 reads out the special drawing lottery result after confirming whether or not the symbol display unit 9 can perform the variation process of the new special diagram, and displays the special drawing lottery result in the symbol display unit 9. To start special figure variation processing. In addition, when the process of changing a new special figure cannot be performed (when the process of changing the special figure related to the lottery result of the previous special figure is being performed, or when the jackpot process described later is being performed) The special drawing lottery results are stored in the special drawing reserved ball storage area with an upper limit of four.

In the special figure changing process, the main circuit 120 receives the lottery result of the read special figure, determines a symbol to be displayed, and stops the special symbol display unit of the symbol display unit 9 with the determined symbol. If you stop at the jackpot symbol, you will be in a jackpot state. Note that the probability of stopping at the jackpot symbol (hit probability) is set to 1/395, for example, in the normal state, and 1/50, for example, in the probability variation state. When the jackpot symbol is stopped, the probability that the jackpot symbol is a normal jackpot symbol is set to 4/10, for example, and the probability that the jackpot symbol is a probabilistic jackpot symbol is set to 6/10, for example. When the jackpot state is reached, the main circuit 120 starts a jackpot process in which the opening / closing operation of the jackpot 11 is repeated a predetermined number of times.

When a ball is won in the opened big prize opening 11, the big prize detector 113 detects this and a big prize detection signal is transmitted to the main circuit 120. The main circuit 120 pays out a predetermined number of prize balls based on the big winning detection signal, and determines whether or not the maximum number of balls (for example, ten balls) to the big winning opening 11 is detected. . Here, when the winning of the maximum number (10) of balls is detected, the main circuit 120 closes the large winning opening 11.

On the other hand, when the maximum number of winning (10) balls is not detected, the main circuit 120 determines whether or not the opening time of the large winning opening 11 has passed the maximum opening time (for example, 25 seconds). Here, when the maximum opening time (25 seconds) has elapsed, the main circuit 120 closes the big winning opening 11.

In this way, one round is defined as the time when the big prize opening 11 is opened once and is closed, and the main circuit 120 opens the big prize opening 11 until the number of rounds reaches the maximum number of rounds (for example, 15). And the closing operation are repeated. When the number of rounds reaches the maximum number of rounds, the main circuit 120 ends the jackpot process. In addition, when the special figure that triggered the jackpot processing is a normal jackpot symbol, it will be in a normal state, and when it is a probabilistic jackpot symbol, it will be in a probabilistic state.

As described above, according to the second embodiment, the transparent plate 2 ′ provided on the front surface of the game board 3 is formed so as to follow the game board 3 formed in a curved shape through a gap through which balls pass. Therefore, the ball is limited and moved within the curved game area formed by the gap between the game board 3 and the transparent plate 2 ′, so that a three-dimensional game area with a depth (three-dimensional game space) is used. Compared to this, the degree of freedom of movement of the ball is limited, but the ball flows down along the curved game board surface, and the nails planted on the game board surface can be used effectively. Although it is similar to a game board, new game play can be obtained. In addition, there is less risk of the ball jumping greatly in the three-dimensional game space, etc., and damaging the transparent plate or the big prize opening.

The embodiments of the present invention have been described above. However, these are merely examples, and the present invention is not limited to them, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.

For example, in each of the above-described embodiments, an example in which the entire game board 3 is formed in a curved shape has been described. However, it goes without saying that the present invention can be similarly applied to a case in which a part of the game board 3 is curved. .
