Description

[Detailed Description of the Invention] This invention provides, in a separate game of pachinko,
Although the probability of occurrence is low, a special game is started by achieving specific conditions, and in this special game, the special variable prize winning device is changed to a state where it is easy to win a hit ball, and while this special game is continuing, the special variable winning device is entered. When the ball hits a special condition, the next special game is repeated after the end of the special game, and the probability of achieving the specific condition in another game is changed and controlled in multiple stages. This invention relates to a pachinko game method that can generate game states that are rich in variety and cannot be played.

As is well known, a pachinko game starts when a player hits a ball, and the ball flows down the playing area formed on the surface of the game board, hitting obstacle nails, and enters the winning slot on the way, becoming a safe and winning a certain number of balls. The prize ball is ejected to the player, and if the ball does not enter any of the winning holes, it will be guided to the out hole at the bottom of the game and become out, and in the process of the shot ball flowing down, it will become safe or out. It was carried out by

In such conventional pachinko games, it is almost impossible to expect that a large number of safes will occur continuously in a short period of time, and it is difficult to predict how many balls will be safe out of a large number of balls hit. It could easily become a monotonous game where players compete for the winning rate. On the other hand, if the winning rate is high, it will be disadvantageous for the pachinko game parlor, which will hinder its business, and if the winning rate is low, the players will be disadvantaged and lose interest in pachinko games.

Therefore, in the conventional pachinko game where players only compete for the winning rate, which tends to be monotonous, the present invention starts a separate game when the first condition is achieved, and when a specific condition happens to be achieved in this separate game, although the probability of occurrence is low, the player By starting a special game that can give a large amount of profit in a short period of time, and controlling the probability of achieving specific conditions in this separate game in multiple stages, it is possible to create a special game in addition to the conventional game. It is possible to enjoy a variety of game states that have both the expectation of being able to play the game and the attraction of being able to obtain a large profit, and also to be able to enjoy the states that occur, and to reduce the probability of occurrence. By controlling the fluctuations, the difference in skill between players is relatively alleviated, making the pachinko game more fair.

More specifically, the content of the game is to set a first condition to be achieved based on the ball hit in the game section, and when the ball hit by the player achieves the first condition, a variable display section or the like will display a different game. When the special condition for which the probability of occurrence is set in advance is achieved when this separate game ends, the special variable prize winning device changes to a state in which it is easy to win a prize by hitting a ball, starts the special game, and during the first special game If the special condition is achieved by hitting a ball in the second special game, the second special game will be repeated after the first special game ends, and if the special condition is achieved by hitting the ball during the second special game, the second special game will be played again.
After the first special game ends, the next special game is started, and the probability of achieving the specific condition in the other game can be changed to multiple levels, so the special game can be played by achieving the special condition. By continuing to play over and over again, great profits can be brought to the player step by step. In addition, by making it possible to change the probability of occurrence of a specific condition being achieved in a different game to multiple levels, for example, a pachinko game parlor can control the winning status of each individual pachinko machine, which can improve the management of the pachinko game parlor. The status can be adjusted as appropriate based on the business policy.

Embodiments of the present invention will be described in detail below based on the drawings.

In FIG. 1, a pachinko machine 1 has a ball supply tray 2 on its surface, and when a player puts a ball into the supply tray 2 and operates the operating section 3, a firing device 4 is activated. The balls you put in are fired one after another. The fired ball is guided above the game part 7 formed on the surface of the game board 6 through the guide rail 5, and flows down the game part 7 while hitting an obstacle nail. If the ball enters the prize opening 8 while it is flowing down in the game section 7, it becomes safe, and a prize mechanism (not shown) provided on the back side of the game board 6 operates, and a certain number of prize balls are delivered to the supply tray 2 or the pachinko machine 1. The liquid is discharged into a saucer 2' provided below the surface. However, if the batted ball flowing down the gaming section 7 does not enter any of the winning holes 8, it enters the out opening 9 provided at the lower end of the gaming section 7 and is confiscated.

A first condition to be achieved by hitting a ball is set in the gaming section 7 described above. According to the embodiment of the drawings, this first condition is that the ball enters either the left or right special winning openings 10a, 10b provided above the gaming section 7, or the specific winning opening provided below the gaming section 7. This is achieved by the ball passing through the frame 10c. This first condition is determined by the obstacle nail and the special winning opening 10a,
Make it difficult for the ball to hit 10b, or set the special winning frame 10
It is possible to make it difficult for a batted ball to pass through c.
In addition, specific winning slots 10a, 10b and specific winning slot 1
A switch mechanism is provided at each point 0c, and when a batted ball enters or passes by, the switch mechanism is momentarily turned on and detects the fulfillment of the first condition.

If the batted ball happens to enter one of the specific winning slots or pass through a specific winning slot and the first condition is achieved,
A separate game is started by the electrical connection means. According to the embodiment shown in the drawings, this separate game is performed by rapidly changing the three variable displays 11a, 11b, and 11c. Each variable display may be made mechanically by rotating a drum or disk displaying 10 numbers from 1 to 10 at high speed, or it may be a segment display with 7 segments arranged in a Japanese character shape. This may be done by electrically controlling the device to rapidly change the numbers from 1 to 0.

In any case, when the ball hits the first condition, another game starts on the variable display, and this other game continues for a predetermined period of time (for example, 7 seconds). During this predetermined time, for example, if a player operates the stop switch 12 on the surface of the Pachinko machine, the high-speed changes of the variable indicators 11a, 11b, and 11c will intermittently stop, and any number from 1 to 0 will appear in the window. is displayed. Furthermore, if the player does not operate the stop switch 12 within a predetermined time during another game, the high-speed changes of the variable indicators 11a, 11b, and 11c will be stopped intermittently by the electrical control means when the predetermined time ends. The game stops in the same state as when the player operated the stop switch 12.

Even if a separate game is started in this manner, the player will not receive much of a profit unless the specific conditions are met. However, if a specific condition is achieved through a separate game, the player can benefit greatly. This specific condition is, for example, each variable display 11a, 11b,
This is the case when all the numbers "7" are aligned in the window 11c and the vehicle stops, and in other cases, there is no specific condition. This specific condition is determined by a determination circuit that determines the stopped state of each variable indicator.

When a specific condition is achieved by a separate game, the special game started in the game section 7 changes to a state in which the special variable prize winning device 13 provided in the game section 7 in the embodiment of the drawings can easily accept the batted ball, and this state This is done by continuing for a predetermined period of time. This special variable prize winning device 13 has, for example, a horizontally elongated opening 14, and guide pieces 15a and 15b are provided at a certain distance below the opening 14 on the left and right sides, and auxiliary guides are provided on the left and right above the opening 14. Pieces 16a and 16b are provided.

Both guide pieces 15a and 15b described above are connected to electromagnets 17a and 17b provided on the back surface of the game board 6. That is, the tips of the rods 18a, 18b of each electromagnet 17a, 17b are connected to the operating rods 19a, 1.
9b, and the actuating rods 19a, 19
Pins 2 of pivot rods 21a, 21b whose base ends are pivotally connected to operating frames 20a, 20b provided at the tips of
2a, 22b, and the rotating rods 21a,
The support pins 23a, 23b provided at the tips of 21b are passed through the game board 5 and protruded from the surface, and the guide pieces 16a,
16b is attached, and each support pin 23a, 23
b communicates with the arcuate holes 24a and 24b.

When the electromagnets 17a and 17b are in a demagnetized state, the support pins 23a and 23b are connected to the arcuate holes 24a and 24b.
The guide pieces 15a and 15b are located at one end and are spaced apart from each other below the opening 14. Therefore, most of the batted balls flowing down the gaming section 7 are sent to the opening 1.
I can't get into 4.

However, when each electromagnet 17a, 17b is energized, the rods 18a, 18b are attracted, and the actuating rod 19
Rotating rods 21a, 21 due to rotation of a, 19b
b turns, so the turning rods 21a, 21b
Each guide piece 15a, 15b at the tip moves along the arcuate hole 24a, 24b, and each guide piece 15a, 15b is located at the lower edge of the opening 14 (second
Figures 3 and 3 (dashed line). This state is a special game, and the batted ball flowing down the game section 7 is guided by the guide piece 15a,
15b and rolls into the opening 14, becoming a safe ball.

Therefore, in the special game described above, each electromagnet 1
It starts when the electromagnets 7a and 17b are excited, and continues for the time that the electromagnets 17a and 17b are excited, and when the electromagnets 17a and 17b are demagnetized, it returns to its original state due to the force of the spring and its own weight.

The auxiliary guide pieces 16a, 16b are connected to auxiliary electromagnets 25a, 25b provided on the back side of the game board 5, and auxiliary operating rods 26a, 26b and auxiliary rotation rods 27a, 2, in the same way as the guide pieces 15a, 15b.
7b, auxiliary electromagnets 25a, 25
If b is demagnetized, each auxiliary guide piece 16a, 16
Both auxiliary electromagnets 25a and 25b are energized, and each opening 1 is located above the opening 14.
Located on the side edge of 4. This auxiliary guide piece 16a,
The action of 16b will be described later.

As described above, when a specific condition is achieved through a separate game, the electromagnets 17a and 17b are excited, and the opening 14
Each guide piece 15a, 15b is positioned on the lower side of the ball, making it a special game where it is easy to receive the ball, and the ball flowing down the game part 7 continuously enters the opening 14 and becomes a safe ball. The opening 14 has a continuation port 28 into which it is difficult for a batted ball to enter, and if a ball that enters the opening 14 during a special game happens to enter the continuation port 28, the ball will flow down the special channel 29. Detected by special switch 30.

When the special switch 30 detects the ball in the channel 29, the second special game continues after the special game ends. In other words, during the special game, the ball is continuously hit in the second slot.
8, when the special condition is achieved, the special switch 30 is turned on, and the electromagnet 17 that was energized is turned on.
After a and 17b are demagnetized, they are re-energized and the second special game is repeated. If a ball hits the continuation slot 28 during the second special game, the third special game is repeated even if the second special game ends. Therefore, if a specific condition is achieved during the continuation of the special game, it will be repeated one after another.

However, if the special condition is not achieved by the batted ball that enters the opening 14 during the special game, the special game ends when the special game ends.

In this way, according to the present invention, if the ball hits the first condition within the game section, a separate game will occur, and if a specific condition is achieved in the separate game, a special game will occur that can bring significant profits to the player. If the special condition is achieved during the continuation of the special game, the special game is repeated again after the special game ends. Therefore, as long as the special conditions are met, the special game will be repeated as many times as necessary, resulting in an extremely large profit for the player, but a significant disadvantage for the pachinko game parlor.

Therefore, as another embodiment of the present invention, the upper limit of the number of repetitions of the special game is set in advance to a constant value (for example, 10 times), and when the special game is repeated a certain number of times, the special game is ended even if the special condition is achieved. That's what I did.

The number of repetitions of this special game is determined by the number of times set by the counter circuit, and once the electromagnets 17a and 17b are energized the number of times set by the counter circuit, the electromagnets 17a and 17b will be energized even if a repeat signal is input from then on. The special game is ended by the electric control means.

The pachinko machine of the present invention will be explained below based on the block diagram of FIG.

The batted ball flowing down the gaming section 7 enters the specific winning hole 10a,
10b or when the first condition is achieved by passing through the specific winning slot 10c, each winning slot 10a, 1
0b is the detector 10b, 1 facing the winning slot 10c.
0c is input from the OR gate 31 to the register 32, and the flip-flop 31a,
31b and 31c are set. As a result, the low level of the Q output of each lip-flop 31a, 31b, 31c becomes high level, and this high level signal is transmitted to the AND gates 32a, 32 connected individually.
b, 32c, each time there is a signal from each oscillator 33a, 33b, 33c, 10
A check signal is input to advance counters 34a, 34b, and 34c.

Upon receiving the above check signal, each decimal counter 34a, 34b, 34c outputs 1, 2, to 0 through the driver to the variable display 11a, 11b,
11c. Therefore, each variable display changes rapidly with the numbers from 1 to 0 invisible.

This operating state is a separate game, and this separate game continues for a certain period of time (for example, 7 seconds). In this separate game, for example, the player presses the stop switch 1 within a certain period of time.
When 2 is operated, an input is input through the OR gate 35 to the reset side of the flip-flop 31c. When an input is input to the reset side, the Q output of the flip-flop 31c becomes a low level, so the AND gate 32c whose input is connected to this Q output closes, and therefore the decimal counter 34c changes to the AND gate 32c.
The variable display 11c stops counting at the number it was counting just before closing, and the variable display 11c visually displays that number.

On the other hand, since the Q output becomes a high level due to the state reversal of the flip-flop 31c, the timer 37b connected to this output operates and outputs a high level after a predetermined time, for example, 1 second. emanate. Since this output is given to the reset input of the flip-flop 31b, the decimal counter 34b is stopped by the same effect as the flip-flop 31c, and the number is displayed on the variable display 11.
b, and another timer 37a is activated by inverting the Q output of the flip-flop 31b.
to operate. Since the output of this timer 37a is connected to the reset input of the remaining flip-flop 31a, when the predetermined time set in this timer elapses, for example, 1 second, the timer 37
The state of the flip-flop 31a is also reversed due to the high level output generated by the flip-flop 31a. Therefore, similarly to the above, the decimal counter 34a counts a fixed number and stops while outputting it, so the corresponding variable display 11a also stops displaying that number.

A timer 38 is connected to the Q output of the flip-flop 31c, which is first reset by the operation of the stop switch 12, and this output is connected to the OR gate 3.
Since the reset input of the flip-flop 31c is connected to the reset input of the flip-flop 31c via the timer 3, the timer 3 is
8 is in operation. After a certain period of time set in the timer 38 has elapsed (for example, after 7 seconds), the state of the flip-flop 31c is forcibly reversed and the above-described circuit operation occurs. This is because even if the player does not press the stop switch 12 carelessly or intentionally, the circuit system including the counter will be returned to the initial state after the set time of the timer 38 has elapsed.
In other words, the purpose is to end another game, and if there were no timer 38, the other game would continue unless the stop switch 12 is operated.

As described above, each decimal counter 34a, 3
When 4b and 34c output their respective predetermined count values and stop, the binary coded decimal output, that is, 1-2-4-
Each 4-bit output with a weight of 8 is processed by a comparator or discriminator circuit 40, which is a combination of ordinary matching circuits, etc.
is input. This discrimination circuit 40 includes first, second,
Emit a third output. For example, when the first output 41a is a predetermined decimal value, such as "7" (all three digits on the display are set to "7"), the second output 41b is the counter 34c,
The decimal value of the output of only 34b is the same (that is, only variable indicators 11c and 11b are "1", "1", and "4")
and the same number such as "4"), the third output 41c is activated in other cases.

When the first output 41a is transmitted, it is the start of a special game, and this output is given to one input of an AND gate 42a, and the other input of the AND gate 42a is the Q of the flip-flop 31a which is finally reset with respect to the counter. connected to the output.
Therefore, the AND gate 42a is opened and a high level is applied to one input of the other AND gate 44a via the OR gate 43. This AND gate 44a
The other input is the Q of a flip-flop 45a whose set input is connected to the output of this AND gate 44a.
Since the output is being received, the AND gate 44a performs an AND operation, and the flip-flop 45a is inverted to set the Q output to a high level. Of course, at the same time, the Q output of flip-flop 45a becomes low level, so flip-flop 45a is set.
AND gate 44a is closed at this point.

When the flip-flop 45a is set in this way, the high level Q output is sent to the three-input AND gate 4.
It is given to one input of 6a.

On the other hand, the other input which is the inverting input of this AND gate 46a is this AND gate 46a.
A 4-bit parallel output terminal with a clock input connected to the output of 6a (for convenience, 0, 1, 2, 3 from the lowest
The shift register 47a receives feedback from the least significant bit (No. 3) of the shift register 47a with a number of Since it is inverted and reset by the low level Q output in the set state, this AND gate 46a is in a state where it is controlled by the remaining input. The last input of the AND gate 46a is the output of the oscillator 48, which generates a high-level pulse signal at an appropriate frequency.
The output of the AND gate 46a becomes high level according to this frequency, and each time the output of the AND gate 46a becomes a high level, the shift register 47a
sets the output to "1" or high level one bit at a time. This continues up to the most significant bit (No. 3), but the process is completed by OR gate 49a at No. 1 output.
The driver 50b operates via the electromagnet 17a.
will be excited. After a slight delay, the driver 50c is activated via the OR gate 49b due to the high level transition of the No. 2 output, and the electromagnet 17b is excited. Furthermore, when No. 3 output becomes high level, AND
Since the inverting input of gate 46a is inverted, the corresponding
AND gate 46a is closed and shift register 47
All bits of a become "1" and stop.

Therefore, since both electromagnets 17a and 17b continue to be excited, each guide piece 15a and 15b is located at the lower side of the opening 14, and the special game continues.

The timer 51a, which is activated by the high level transition of the No. 3 output of the shift register 47a, ends the continuation of this special game after a certain period of time.

That is, after the timer 51a is activated (electromagnet 17a,
17b) for a set period of time (e.g. 30
seconds), a high level output is emitted. This output is given to one input of an AND gate 52a whose output is connected to the reset input of the flip-flop 45a, and the other input of the AND gate 52a is already at a high level at this point due to the feedback of the Q output of the flip-flop 45a. Therefore, the AND gate 52a is closed at the same time as the flip-flop 45a is reset by the output of the gate 52a, and returns to the original state.

By resetting the flip-flop 45a described above, the shift register 47a, which inverts the Q output and uses it as a reset input, is reset, and all bits become 0 or low level. As a result, the shift register 47a also returns to its initial state, so both electromagnets 17
a, 17b are demagnetized and the special game ends.

Note that the special game continues when the timer 51a
The operating time of each circuit (shift time, etc.) is added to the set time (30 seconds) of the timer, but since the operating time of each circuit is negligible compared to the set time of the timer, It is recognized that the excitation time is determined by the timer 51a.

According to the above, each detector 10a', 10b', 10
When c' is turned on, the decimal counter 34 is started by operating the stop switch 12 or by counting up the timer 38.
a, 34b, and 34c stop, and their output numbers are all "7" (that is, the weight output of 1-2-4 is "1", and the output of weight 8 is "0"), and both electromagnets 17a,
17b is energized and demagnetized after 30 seconds.
That is, one period of operation of one special game can be concretely understood.

However, if the batted ball that entered the opening 14 during this cycle of operation continues, enters the continuation port 28, flows down the special channel 29, and turns on the special switch 30,
Since both electromagnets 17a and 17b are excited for 30 seconds, the special game is repeated. That is, the Q output of the flip-flop 45a before being reset by the timer 51a is applied to the other input of the AND gate 53, which has the output of the special switch 30 as one input. Therefore, both electromagnets 17a,
If the special switch 30 is turned on while 17b continues, the AND gate 53 opens and the flip-flop 5
4 will be set. This flip-flop 54 is a storage circuit until information about the next electromagnet excitation operation arrives, and then sends a signal for exciting both electromagnets as a high level Q output to one input of an AND gate 55 and waits. . Then, after the first special game ended, as mentioned above,
When the output of AND gate 52a becomes high level,
One-shot multivibrator circuit 56 emits one pulse, and this pulse is applied to AND gate 55. Therefore, in AND gate 55,
As described above, an AND operation is performed with the high level Q output of the flip-flop 54, which is already on standby, and a high level signal is sent to one input of the AND gate 44a via the OR gate 43.

If this happens, the discrimination circuit 40 described earlier
Since the same operation is started by the first output 41a from the timer 51, both electromagnets 17a and 17b
The special game is repeated by excitation for the time set in a.

Furthermore, the one-shot multivibrator circuit 56
The output of the flip-flop 54 is reset through the OR gate 57, and the reset flip-flop 54 stores the signal when the special condition is achieved and the special switch 30 is turned on during the repeated special game. Become. If the special condition is not achieved, there will be no signal from the special switch 30, so after the special condition ends, all the circuits will return to their original state, and if there is a signal from the special switch 30, the special game will be repeated again. Become.

That is, there is a possibility that the excitation operation of both electromagnets 17a and 17b to continue the special game under preset conditions can be continued an infinite number of times with the continuation conditions as one basic unit. In other words, even during the special game, if the player continues to hit balls and the special condition is achieved with even one of the balls, the special game with the same conditions will be repeated again, so the special condition will be achieved during the special game. As long as you do so, the special game will be repeated an infinite number of times.

In order to prevent this, the repetition of the special game may be stopped by so-called stopping. However, as is well known, stopping is done by controlling the supply of prize balls to a tank provided on the back of the pachinko machine, which results in uneven limits on the number of special games. For example, the repetition of the special game will be different depending on whether the prize balls are replenished 3 times and the game is stopped, or when the game is stopped after the 5th game, and the player can play the special game that happens to occur. will be killed.

Therefore, in order to limit the number of repetitions of the special game to a constant value (for example, 10 times) using an electrical control means,
The present invention adds the following circuit configuration.

Set the N-ary counter 58 to, for example, N=10.
A decimal counter is used, and a carry signal from the counter 58 is used to reset a flip-flop 54 as a special switch signal storage circuit via an OR gate 57. The N-ary counter 58 counts once from the basic unit of the first special game, and counts this basic unit 10 times. Therefore, the carry signal from the counter 58 is not output until the 9th basic unit, so every time there is an output from the special switch 30 for each special game, the flip-flop 54, which is a memory circuit, memorizes that fact, and the special When the game ends, the next special game is played. However, when the 10th special game is played, the N-ary counter 58 continues to issue a carry signal to keep the reset input of the flip-flop 54 at a high level, so even if there is an output from the special switch 30 during that time, the Q of the flip-flop is The output is pulled to a low level. Therefore, during the 10th continuation of the special game, the special switch 30
Even if there is an output of
The second special game does not occur.

In order to cause such an operation, the N-ary (decimal) counter 58 requires the following conditions.
That is, the count must be reset before the first time the special game starts, and the count must be increased by "1" every time the special game is played.
Such conditions can be easily set by a person skilled in the art by constructing arbitrary logic, but in the embodiment shown in the drawings, processing is performed as follows.

First, the counter is reset using the first output 41a of the discrimination circuit 40, which is the starting condition for the first special game, and the repeated count of the special game is performed using the timer 51a, which is activated after the electromagnets 17a and 17b are energized. The signal (signal to the AND gate 52a) is used as a counter input. Therefore, the decimal counter 58 before the first start of the special game is reset by the first output 41a, and when the special game is repeated 10 times and the signal from the timer 51a is given 10 times, a carry signal is generated and the flip-flop is activated. 54 is reset, the 11th special game will not be played.

In addition, for convenience during maintenance and inspection,
In this embodiment, a monitor switch 39 is provided on the back of the pachinko machine, and when the monitor switch 39 is operated, the output of this switch is sent to each decimal counter so that each decimal counter 34a, 34b, 34c will all output the decimal number "7". It's in the preset input. However, the flip-flops 31a, 31b, 31c, which operate the respective counters 34a, 34b, 34c by turning on the respective detectors 10a', 10b', 10c', are arranged so that this monitoring is possible only when they are all in the reset state. AND gates 36a, 36b, and 36c are provided in the signal line from the monitor switch 39 to the preset input to perform an AND operation with the Q outputs of the corresponding flip-flops 31a, 31b, and 31c. The explanation up to this point is based on the case where the first condition is achieved by hitting a ball and a separate game is started, and in this separate game, the specific condition is achieved and a special game occurs, and the first output 41a is transmitted from the discrimination circuit 40. Everything works.

However, if the specific conditions are not achieved in another game and it becomes the first profit game, that is, each 10
A case will be described in which the decimal values of only the counters 34c and 34b among the decimal counters 34a, 34b, and 34c are aligned and the discrimination circuit 40 issues the second output 41b.

In this case, the profit level for the player is much lower than that of the special game, and the second output 4
1b and the Q output of flip-flop 31a, which has been reset as described above, is ANDed.
The AND output is taken by an AND gate 42b and given to one input of another AND gate 44b. Since the other input of this gate 44b receives the Q output of the flip-flop 45b which uses this gate output as the set input, the AND gate 44b is also opened, and the flip-flop 45
b is set and the Q output becomes high level. At the same time, the Q output becomes low level and the AND gate 44b
closes. On the other hand, the high level signal of the Q output due to the setting of the flip-flop 45b is sent to one non-inverting input of a three-input AND gate 44b having one inverting input, and the inverting input is a 6-bit parallel output which receives the output of this gate 46b as a clock. Since this output is at a low level, the AND gate 44b receives the most significant bit output of the shift register 47b, which has a terminal. Through,
Therefore, the shift register 47b starts from the LSB.
The parallel bit output is sequentially set from "1" to high level toward the MSB. As a result, the auxiliary electromagnet 25a is first excited via the driver 50a, and then
The electromagnet 17b is excited via the OR gate 49a and the driver 50b, and finally the auxiliary electromagnet 25b is excited. and shift register 47b
Then, when the MSB output is set to "1", this output AND gate 46b is closed and the output of the oscillator 48 is no longer given to this register 47b, so each electromagnet 25a, 17a, 17b, 25b is continuously excited. ing. This state is the mode of the first profit game, and each electromagnet 17a, 17b, 25
When a and 25b are energized, the guide piece 1
5a and 15b are located at the lower side of the opening 14, and the auxiliary guide pieces 16a and 16b are located at the left and right sides of the opening 14. Therefore, when a batted ball flowing down the gaming section 7 reaches the opening 14, it is guided by one of the guide pieces and enters the inside, becoming a safe ball, thereby increasing the winning rate of the batted ball.

The first profit game in the embodiment described above does not continue indefinitely, but only for the set time of the timer 51b. This timer 51b is the shift register 4
The operation starts with the MSB output of 7b, and when the set time (for example, 15 seconds) has elapsed, the AND gate 52b performs an AND operation with the set Q output of the flip-flop 45b, and the output of the AND gate 52b outputs the output of the flip-flop 45b. At the same time, the Q output which has become a low level is applied to the reset input of the shift register 47b having an inverted reset input via the OR gate 59a, and the shift register 47b is reset and all the electromagnets 25a, 17a, 17b, 25b
is demagnetized. Therefore, the first profit game is timer 5.
It lasts only for example, 15 seconds as set in step 1b, and there is no repeat function like the special game described above, and when it ends, it returns to the initial state with the second output 41b.

In addition, the structure of the code|symbol which added b to the number in the circuit of the 1st profit game is the same as the structure of the circuit in the previous special game.

On the other hand, if the player's batted ball achieves the first condition in the game section, but does not achieve anything in another game, and the discrimination circuit 40 issues the third output 41c, the second condition is determined.
It becomes a profit game. This second profit game has even less profit status for the player than the first profit game, and the circuit configuration of this second profit game is almost the same as the circuit configuration of the first profit game, as is clear from the drawings. To explain the electrical processing mode of this second profit game, the third output 41c and the Q output of the flip-flop 31a are ANDed by an AND gate 42c, and this AND output is given to one input of another AND gate 44c. . This AND gate 44c is opened because its other input receives the Q output of the flip-flop 45c, and the flip-flop 45c is set and the Q output becomes high level. The high level signal of this Q output is sent to one non-inverting input of a three-input AND gate 46c having one inverting input, and the inverting input is a shift register 47c having a 4-bit parallel output terminal which receives the output of this gate 46c as a clock. Since this output is at a low level, every time the output of the oscillator 48 is input to the other non-inverting input,
The AND gate 46c passes this, and therefore the shift register 47c sequentially changes the parallel bit output from "1" to high level from LSB to MBS. As a result, the electromagnet 17a is first excited via the OR gate 49a and the driver 50b,
Next, the electromagnet 17b is excited via the OR gate 49b and the driver 50c, and this output that sets the MBS output to "1" closes the AND gate 46c and the output of the oscillator 48 is transferred to the register 4.
7c, both electromagnets 17a,
17b is continuously excited. This state is the mode of the second profit game, and both guide pieces 15a and 15 are attached to the lower side of the opening 14 by excitation of both electromagnets 17a and 17b.
b is located, and a part of the ball hits both guide pieces 15a, 1.
5b, the ball flows into the opening 14 and becomes a winning ball.

Therefore, in the second profit game, the electromagnets 17a, 1
7b is energized, the guide pieces 15a and 15b are positioned at the lower side of the opening 14 to receive the batted ball flowing down the gaming section, and this state continues for the time set by the timer 51c (for example, 5 seconds). The timer 51
Shift register 47c as well as timer 51b
It operates with the MBS output of
The AND gate 52c performs an AND operation with the Q output of the flip-flop 5c, and the output of the AND gate 52c resets the flip-flop 45c to return to its initial state. The reduced Q output is applied, the shift register 47c is reset, and both electromagnets 17a and 17b are demagnetized.

Therefore, the second profit game continues for, for example, 5 seconds set by the timer 51c, and the first
Like profit games, there is no repeat function.

In addition, in the second profit game, the configuration of the symbol with C added to the number is the same as the circuit configuration in the special game.

In addition, in the circuits for the first profit game and the second profit game, OR gates 59a and 59b are provided in the reset signal lines to the shift registers 47b and 47c,
The reason why the other inputs of the OR gates 59a and 59b are connected to the reset signal line to the special game shift register 47a is that even when the circuit system is operating due to the first profit game or the second profit game, when the special game is reset at the same time, This is because all electromagnets were first demagnetized.

Next, an example of special game occurrence probability control will be described, for example, when the settings are changed electrically from the outside.

Now, three decimal counters 34a, 34b, 34
Assuming that the output of c is not modified in any way, in decimal terms, the probability that all of these output numbers are a single number, for example "7", is 1 in 10, or 1 in ³ .
It is 1/1000, and the specific condition is achieved only 1 out of 1000 times in another game. Considering the state of the weighted bits of each decimal counter in this case, it becomes "0111" starting from the weight 8.

However, the output of any one of the third counters (for example, the decimal counter 34a), for example, the LSB, that is, the output of weight 1, is pulled up to the power supply potential +Vcc as shown by the connection line 60a, and becomes "1". If the value is fixed to , the remaining 8-4-2 bits are "011" and there is a decimal number "6" (0110) in addition to the decimal number "7" (0111). That is, actually the counter 34
Even if a outputs "6", it is output as "7", and if the counter 34a outputs "7" or "6", it can be considered that "7" is output. Therefore, this counter 34
The probability that a outputs “7” is determined by the other counter 34
It is 1/5 of half of 1/10 of b and 34c. Therefore, probability counters 34a, 34b,
The probability that all 34cs are 7 is 1/5×1/10×
1/10=500, which increases the probability of a special game occurring. In exactly the same way, if the LSB of the two decimal counters 34a and 34b are pulled up to the power supply potential +Vcc using the connection line 60b and fixed to "1", the probability that each counter "7" will be equal is 1/5 x 1/ 5×1/10=1/250, which is 1/250, and each counter 34a, 3
If both 4b and 34c pull up the LSB through the connection line 60c, 1/5 x 1 x 5/5 = 1/125, and the specific condition will be achieved only once out of 125 times in another game. Of course, this probability change could also be made on any bit output, and instead of pulling it up to supply potential, one of the bits could be pulled down to ground potential, i.e. a binary '0'.
This can also be done by fixing it to .

The electrical operations of the special game, the first profit game, and the second profit game described above are just one example, and the circuits can be freely designed using any other electronic means that can be considered.

It should be noted that the design of the present invention can be changed in any state as long as the structure described in the claims is not changed. For example, as described above, the circuit can be changed appropriately, the number of decimal counters can be changed, etc. , or changing the number of electromagnets so that only the special game can be played, or the special game and either or both of the first profit game and the second profit game can be selectively performed, and the probability of occurrence of specific conditions being achieved. may be changed automatically, the special game may be performed under preset conditions using a timer, etc., or the special game may be set in conjunction with other conditions, such as a restriction on winning batted balls during the special game. In fact, it can be done in any way depending on the circuit configuration.

In summary, in the present invention, when a ball hit by a player satisfies the first condition in the gaming section, a separate game starts, and when this separate game ends, a special condition is created by achieving a specific condition for which the probability of occurrence is set in advance. The game is started, and in this special game, the special variable winning device converts the ball into a state where it is easy to win a prize, and this conversion state continues for a predetermined period of time, and during the continuation of this special game, the ball that enters the special variable winning device becomes a special player. When the conditions are achieved, the next special game is repeated after the end of the special game, and the probability of achieving the specific conditions in the other game can be changed to multiple levels, so the special game can be continued by achieving the special conditions. To provide players with the pleasure of gaining profits step by step and ultimately bring in a large amount of profits, and to provide highly fair game content in which skill disparity between players is relatively alleviated. I can do it. In addition, by changing and controlling the probability of achieving a specific condition in a different game into multiple stages for each individual pachinko machine, profit disparities will occur more evenly than ever before due to fluctuations in the rate of achieving specific conditions due to changes in the probability value. The interest in the game is heightened, and the management content of the pachinko game parlor can be made rational and practical by making it easier to manage profit based on the business policy through external adjustment.
Moreover, the demographics of players at pachinko parlors vary depending on the location.For example, pachinko parlors in downtown areas prefer pachinko games where the outcome can be decided in a relatively short period of time, while in the suburbs Players in rural areas and regions tend to take their winnings seriously and enjoy playing for long periods of time.
By changing and controlling the probability of a specific condition being achieved in a different game in multiple stages in each pachinko machine, the pachinko machine can meet the needs of pachinko game parlors and has high practical value.
