DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a pachinko machine in which a "large role" advantageous to a player is generated when predetermined conditions are satisfied.

[0002]

2. Description of the Related Art Some pachinko machines have a special prize area on a game board and a variable display device for displaying a plurality of types of identification information when a pachinko ball passes through the specific prize area. .

In this type of pachinko machine, when a pachinko ball passes through a specific winning area, a variable display device sequentially and variably displays a plurality of types of identification information, for example, numerals "1 to 9" for a predetermined variable display time. When the display is completed, the variable display device stops and displays any one of the identification information (numbers) from the plurality of types for a predetermined stop display time.

When the identification information stopped and displayed on the variable display device (hereinafter, stop identification information) is predetermined identification information (for example, "7"), the winning probability increase state is provided on the winning device or the accessory. A "large role" continued by the member occurs. With the occurrence of this "big role", the pachinko ball becomes easier to continuously win the prize winning device or the accessory through the guide member, and the number of prize balls acquired per unit time increases, so that the state advantageous to the player continues. Formed. In this way, when the "main role" occurs, the right to acquire a state advantageous to the player is generated. Therefore, the state in which the "main role" is generated is hereinafter referred to as "right" generated. The predetermined identification information “7” for generating the “right” has a constant probability of being stopped and displayed on the variable display device.

[0005]

In other words, since the probability of occurrence of "right" is constant, "right"
When the pachinko game does not occur beyond the set value and the pachinko game is continued for a relatively long period of time, the probability of occurrence of “rights” is close to the set value and the pachinko game is likely to have little change, and the willingness to play the game. Will be reduced.

Accordingly, an object of the present invention is to provide a pachinko machine capable of changing the probability of occurrence of "rights".

[0007]

According to the present invention, as a means for solving the above-mentioned problem, a plurality of types of identification information are variably displayed in a predetermined manner when a pachinko ball passes through a specific winning area provided on a game board. A variable display device for sequentially displaying the variable information only for a predetermined time and stopping the display of any of the identification information for a predetermined stop display time based on the end of the variable display, wherein the predetermined identification information has a predetermined probability in the variable display device. In the case of a pachinko machine in which a stop is displayed based on the value, a large role of maintaining the winning probability increase state advantageous to the player occurs,
Probability value changing means for changing the occurrence probability value of the main role when predetermined specific identification information among the plurality of types of identification information is stopped and displayed on the variable display device is provided.

[0008]

[Operation] With this configuration, when the specific identification information is stopped and displayed on the variable display device, the probability value changing means changes the occurrence probability value of “large role (“ right ”)”. The value does not become constant, and the probability value that a state advantageous to the player is formed can be increased with the progress of the game.

The output signal from the Q output terminal of the latch circuit 106 is input to the AND circuit 125, and the output signal of the 10 count switch circuit 108 is input to the 10 count circuit 109 via the AND circuit 125. The 10 count circuit 109 performs a 10 count operation only when the latch circuit 106 is latched.

The 10-count reset signal of the 10-count circuit 109 (see FIGS. 8 and 9)
6 and is input to the reset terminal of the latch circuit 106 (see J in FIGS. 8 and 9).

Reference numeral 127 denotes a time reset circuit. The time reset circuit 127 outputs a time reset signal when the timer signal becomes H, and inputs the time reset signal to the OR circuit 126. Is reset by one of the 10 count reset signal and the time reset signal.

The time from when the timer signal is output to when it becomes H is the time when the solenoid 59 is excited 18 times by the timer signal. Reference numeral 128 denotes a continuation number counter circuit to which the output signal of the hit latch circuit 106 is input (see I in FIGS. 8 and 9).

The continuation number counter circuit 128 counts up each time the output of the hit latch circuit 106 changes from L to H, and the count value signal corresponding to the count value and the count value become "8". And an 8 count signal which becomes H at the time.

129 is a signal delay circuit, 130 is a continuation number control circuit, 131 is an OR circuit, and the 8 count signal is input to the signal delay circuit 129 via the inverter 132, while the continuation number control circuit 130 It is directly input (see E and F in FIGS. 8 and 9).

The OR circuit 131 includes these circuits 129, 130
The output signal of the OR circuit 131 is input to the AND circuit 119.

Reference numeral 141 denotes an AND circuit.
The output of the motor stop timing detection sensor 91 and the output of the hit latch circuit 106 are input to the, and the output is input to the hit detection switch circuit 105 through the OR circuit 139.

Therefore, when the hit latch circuit 106 outputs H, the pachinko ball wins only in the specific winning opening 26, and the hit detection switch circuit 105 depends on the type of picture displayed on the leaf display 40. The H pulse is output without any condition.

142 is a delay circuit, 143 is an AND circuit, 144
Denotes a hit storage latch circuit, 145 an inverter, 146 an AND circuit, and 147 a differentiation circuit.

The output of the hit latch circuit 106 is input to the delay circuit 142, and the output of the AND circuit 121 and the output of the delay circuit 142 are input to the AND circuit 143.
When 106 outputs H, the hit detection switch circuit 121
When a high-level pulse is output from the memory, the hit storage latch circuit 144 is latched, and its output becomes H.

The output of the latch circuit 144 is
6, and the output of the delay circuit 142 is also input to the AND circuit 146 via the inverter 145.

The output of the AND circuit 146 is
Is input to the hit latch circuit 106 via the
When the output of the latch circuit 106 changes to H or L, the output from the inverter 145 switches from L to H after the delay time of the delay circuit 142 elapses. Be replaced.

At this time, if the latch circuit 144 is latched, the input of the hit latch circuit 106 changes from L to H, and the hit latch circuit 106 is latched.

The output of the hit latch circuit 106 is input to the differentiating circuit 147, and the output is input to the reset terminal of the hit storage latch circuit 144. This makes the hit latch circuit 10
When the output of 6 changes from L to H, the hit storage latch circuit

The timer signal of the timer circuit 110 is input to the solenoid drive circuit 132, the timer signal is input to the demonstration display drive circuit 133, and each timer signal is amplified by the drive circuits 132 and 133 and the like, and the solenoid 59 and LED

Reference numeral 134 denotes a lamp lighting control circuit, 135 denotes an AND circuit, 136 denotes a lamp driving circuit, and a timer signal and an output signal of the lamp lighting control circuit 134 are input to the AND circuit 135. The output signal of the AND circuit 135 is amplified by the lamp drive circuit 136 and supplied to the demonstration lamps 22 and 24.

Reference numeral 137 denotes a numerical value display driving circuit. The numerical value display driving circuit 137 receives the count value signal of the 10-count circuit 109 and the count value signal of the continuation number counter circuit 128.

The numerical value display drive circuit 137 causes the count value signal to display the count value on the 10-count display 21 by the count value signal, and sets the LEDs 36-1 to 36-8 to the count value by the count value signal. Light up the corresponding number.

Next, the operation will be described. First, if there is no winning in either of the first and second starting winning ports 13, 14, 14, none of the latch circuits 96, 99 is latched, and the latch circuit 106 is also not latched. It is in the normal gaming state.

As a result, since H is input to the timer control circuit 116, the output of the timer circuit 110 is prohibited, and the solenoid 59, the demonstration LED 39, the lamp
Neither 22 nor 24 is driven.

On the other hand, since the latch circuit 104 is also not latched, the output signal from the Q-bar output terminal is H, and the motor 69 is driven to rotate by the motor drive circuit 138. Variable display is performed.

Next, for example, when there is a prize in the first start winning port 13, the first start latch circuit 96 is latched, so that one input to the AND circuit 114 becomes L. Input, the timer circuit 110 starts outputting, the solenoid 59 is excited, and the guide vanes 34, 34 open,
The LED 39 and the lamps 22 and 24 are turned on.

When a predetermined time elapses after the timer circuit 110 starts outputting, the timer signal goes high, so that the latch circuit 96 is reset, the output of the AND circuit 114 goes high, and the output of the timer circuit 110 is inhibited.

During this time, if there is no winning in the specific winning opening 26, nothing happens. On the other hand, when there is a winning in the specific winning opening 26, a detection signal of the winning ball is output from the motor stop command ball detection switch 100, and the latch circuit 102 is latched.
Subsequently, the latch circuit 104 is latched by the detection signal of the stop timing detection sensor 91.

Therefore, the output signal H from the Q-bar output terminal of the latch circuit 104 becomes the output signal L (see H in FIGS. 8 and 9), and the motor 69 is stopped by the motor drive circuit 138. After the picture on the display 40 is variably displayed for a predetermined variable display time, one of the pictures is stopped and displayed for a predetermined stop display time. At the same time, the hit detection sensor 50 determines whether the picture has hit or missed.

Thereafter, since the latch circuit 104 is reset by the self-reset circuit 124, the output signal from the Q-bar output terminal becomes H, so that the motor 69 can After stopping once, driving starts immediately.

When the judgment of the picture is "missing", since the latch circuit 106 is not latched, the output signal of the AND circuit 114 is H, and the output of the timer circuit 110 is inhibited and nothing occurs. The game is continued.

On the other hand, during the normal game, when it is determined that the picture is the specific identification information corresponding to “hit”, the latch circuit 10
6 is latched to generate a "right" and AND circuit 114
Becomes L.

As a result, the timer circuit 110 starts outputting, the guide vanes 34, 34 are opened by the excitation of the solenoid 59, and the LED 39 and the lamps 22, 24 of the pachinko ball are turned on.

Therefore, it becomes easier to win a prize than in the normal game, and the “right” can be exercised. In this case, there are ten types of patterns displayed on the leaf display 40, and three of them correspond to the specific identification information of the "hit" pattern.
The probability of occurrence of “right” is three-tenths.

Since the count value of the continuation number counter circuit 128 becomes "1", the LED 36-1 is turned on, the gate to the 10 count circuit 109 is opened, and the count value is displayed on the 10 count display 21. Is done.

Further, during this time, when the special winning opening 26 is won, the latch circuit 144 is latched as described above and the picture of the leaf display 40 is stopped, but the latch circuit 106 which is the probability value changing means is operated. "Latch" by latch
Regardless of the determination of “missing”, only winning in the specific winning opening 26 is stored and held as “hit”.

In this case, there are ten kinds of patterns displayed on the leaf display 40, and all of the ten patterns correspond to the specific identification information of the "hit" pattern, so that the number of "hit" patterns is larger than that in the normal game. doing.

Therefore, the probability of occurrence of "rights" is 10/10, and the probability of occurrence of "rights" fluctuates before and after the stop display of the "hit" pattern (specific identification information) during a normal game. For example, it has increased from three-tenths to ten-tenths.

When the latch circuit 106 is reset, it is latched again, and the output signal of the AND circuit 114 becomes instantaneous H with the output signal, and the timer circuit 110 enters the initial state and starts outputting again from the beginning. Since the continuation number counter circuit 128 counts up by one with the output signal, the LED 36-2 in addition to the LED 36-1 is turned on.

As described above, when the generation of the “right” is continued eight times, the eight count signal of the continuation number counter circuit 128 becomes H, so that the input from the OR circuit 131 to the AND circuit 119 becomes L.

Therefore, even if there is a prize in the specific winning opening 26 after the eighth stop of the pattern of the leaf-type display 40, the motor 69 is not controlled to be stopped, so that 10 counts or 18 excitations of the solenoid 59 are performed. The "right" at the tenth occurrence probability value disappears, and the game returns to the normal game state.

As a result, the probability of occurrence of “right” returns to 3/10, and the probability of occurrence of “right” before and after the stop display of the “hit” pattern (specific identification information) during the normal game is
It fluctuates from ten-tenths to three-tenths, in this case it decreases.

The occurrence probability value of the “right” which fluctuates before and after the “hit” pattern is stopped and displayed in the normal game is 10
It is needless to say that the ratio is not limited to tenths and three-tenths, but may be arbitrarily determined.

That is, as described above, the probability of occurrence of "rights" is determined not only in two types but also in three or more types, and the type of the pattern to be stopped and displayed is associated with the probability of occurrence of "rights". It may be configured to change the probability of occurrence of subsequent “rights” according to the picture to be performed.

In this embodiment, the leaf-type display 40 is used to display information. However, the present invention is not limited to this. For example, a display composed of a well-known LED, various patterns on the outer surface of the drum, etc. Alternatively, it may be displayed by a drum type or the like depicting the above.

Also, the number of continuations of “right” in the occurrence probability value of 10/10 is not limited to eight, but may be six, ten, fourteen, sixteen, etc.
Obviously, it can be arbitrarily set.

[0141] Furthermore, three winning ports are provided in the center part 10.
Although 26, 27, and 27 are formed, this may be provided at one location. In this case, only one pachinko ball detection switch corresponding to the winning opening may be attached, and may be used for 10 counts and for continuous use.

In the above-described embodiment, the condition for generating the “right” is that the specific winning information is awarded at the time of the normal game and the specific identification information is stopped and displayed.
Only by winning the specific winning opening 26, regardless of the picture judgment, the "right" is generated, and the occurrence probability value of the "right" before and after the stop display of the specific identification information is changed. However, the present invention is not limited to this, and the occurrence probability value of “right” may be changed as follows.

(A) The number of “hit” pictures is changed before and after the “right” is generated. For example, before the "right" occurs, the number of "hit" patterns is one, after the "right" occurs, the number of the "hit" patterns is increased to three, and further, before the "right" occurs, the number of "hit" patterns is two. After the occurrence of the "right", the "right" occurrence probability value is changed before and after the "right" occurrence by changing the number of the "hit" patterns, such as six "hit" patterns.

(B) At the time of the normal game before the occurrence of the “right”, there is one specific winning port 26, and based on the above-mentioned stop display of the specific identification information, the normal winning port after the occurrence of the “right” at the time of the normal game. 27 and 27 are also designated as special winning areas, and the total number of the special winning areas is three.

In such a configuration, the leaf-type display 40 is activated based on the winning ball in the normal winning opening 27, 27 only when the hit latch circuit 106 is latched. The leaf-type display 40 may be activated only for the winning of the specific winning opening 26 only.

As a result, if the openings of the winning openings 26 and 27 have the same shape, the occurrence probability value of “right” varies from one third and three thirds to the other. .

The configuration of (b) can be applied to a pachinko machine without an identification information display corresponding to the leaf display 40 in the above embodiment.

In other words, this pachinko machine is a specific winning opening
When the pachinko ball wins at 26, the state of increasing the winning probability value of the winning device within a predetermined time starts to be maintained, and when the pachinko ball wins at the specific winning opening 26 during the winning probability value increasing state of the winning device, This is a type in which the winning probability value increasing state is started again from the beginning.

(C) The “hit” is greater than before the “right” is generated.
After the “right” based on the stop display of the picture (specific identification information), the specific winning opening 26 is mechanically enlarged.

For example, in (b), instead of changing the number of specific winning areas before and after the occurrence of “rights” in a normal game, this is a boundary between the normal winning openings 27, 27 and the specific winning opening 26. However, the partition plates 28, 28 are constructed so as to be able to come and go freely, and the passing opening range of the specific winning area is changed.

If the openings of the winning ports 26 and 27 have the same shape, the probability that the pachinko ball passes through the specific winning area is changed from one third and three thirds to the other. Then, the occurrence probability value of “right” is changed. In the case of (c), similarly to (b), the present invention can be applied to a pachinko machine without a display.

Furthermore, the embodiments described above, (b) and (c) above may be arbitrarily combined to constitute a pachinko machine.

[0153]

As described above, according to the present invention, when the specific identification information is stopped and displayed on the variable display device, the probability value changing means changes the occurrence probability value of "large role".
The probability of occurrence of the "big role" does not become constant, and the probability that a state advantageous to the player is formed can be increased with the progress of the game.

This gives the player a sense of expectation for the intensive increase of the prize ball at the time of the next occurrence of the “large role”. By giving an extremely large game change to the player, even if the pachinko game is continued for a relatively long time, a reduction in the willingness to play is suppressed irrespective of the occurrence of the “big role”.
