Description

The present invention relates to a pachinko machine.

(Prior Art) In a pachinko machine, a winning probability is obtained by moving a guide member for guiding a pachinko ball to a specific prize area as a space for winning a pachinko ball in a direction of picking up the pachinko ball when predetermined conditions are satisfied. There is a prize device provided with an award winning device which is in an increased state.

Conventionally, this kind of pachinko machine includes a hit detection device that operates with a predetermined probability in relation to the trajectory of the pachinko ball when the pachinko ball enters the specific winning area. The bonus operation of starting the winning probability increasing state of the winning device within the period, and starting the winning probability increasing state from the beginning again when the hit detection device is activated during the winning probability increasing state of the winning device. To do it.

(Problems to be Solved by the Invention) However, due to machine differences caused by product accuracy, installation environment, and the like, the partial structure and shape in the specific winning area are slightly different, and in the specific winning area, The trajectory of the pachinko ball changes, and some of the hit detection devices are relatively easy to operate by jumping out and the other is difficult to reverse.
The following problems occurred.

In other words, first, the case where the hit detecting device is easy to operate will be described. In this type of pachinko machine, the number of times the winning probability of the winning device is increased is limited from the viewpoint of eliminating gambling, and furthermore, as a continuation mode, the hit detecting device When the device is operated, the current winning probability increase state is terminated at that time and the winning probability increase state is restarted again, and the current winning probability increase state is restarted after the predetermined winning period has been performed for two types. Conceivable. When the hit detection device is easily operated, the winning probability increase state is easily created and easily continued. In the former case of the two types of continuous states, the winning device is in the winning probability increasing state. Immediately after that, the case where the hit detection device is activated is continuous and the number of continuations is limited, which means that the role action ends without giving sufficient profit to the player, Cause the player's willingness to play. On the other hand, in the latter case of the two types of continuation mode, the player can acquire a great profit by one action of the accessory, and the action of the accessory is frequently repeated because the winning probability increase state is easily created. Betting is combined with the fact that gambling is enhanced.

Next, if the hit detection device is difficult to operate, it is difficult for the winning probability increase state to be created and continued, and the player ends up without experiencing the winning probability increase state of the winning device, or Alternatively, it is highly likely that the game will end without being continued even though it has been acquired, so that the player's willingness to play is reduced.

The present invention has been made in view of such problems of the related art, and its object is to minimize the influence of machine differences as much as possible and to easily equalize the gaming operation of each gaming table. It is another object of the present invention to provide a pachinko machine that is moderate in view of the improvement of the game performance and the elimination of the gambling property.

(Means for Solving the Problems) For this reason, the pachinko machine of the present invention includes a specific winning area having a predetermined winning opening and another winning opening different from the winning opening, and the predetermined condition is satisfied. A prize device that forms a prize-enabled state in the specific prize area in order to cause a prize in one of the prize ports, and a hit detection that operates with a predetermined probability when a pachinko ball enters the predetermined prize port. A prize probability increasing circuit configured to increase the prize probability to the prize device by being set by the operation of the hit detection device to form the prize possible state, and to maintain the prize probability increase state for a predetermined period; During the set state of the winning probability increasing circuit, when the hit detection device is activated and the predetermined period is ended,
A winning probability increasing state control circuit for controlling the winning probability increasing circuit so that the winning probability increasing state is started again from the beginning; and an operating probability of the hit detection device in a set state of the winning probability increasing circuit. And a probability changing mechanism associated with the corresponding detection device so that the winning probability increase circuit is higher than when it is not in the set state.

(Operation) With such a configuration, the present invention satisfies the predetermined condition in the normal gaming state, the prize device forms the prize possible state in the specific prize area, and the pachinko ball enters the predetermined prize opening. In this case, the hit detecting device operates with a predetermined probability, and when activated, a winning probability increasing circuit is set. With this set, the winning device maintains the increasing state of the winning probability for a predetermined period. Is larger per unit time than the number of winning balls in the normal gaming state.

During the set state of the winning probability increasing circuit, the operating probability of the hit detection device is increased by the probability changing means compared to when the winning probability increasing circuit is not in the set state. Again, after the end of the prize probability increasing state during the predetermined period maintenance at that time, the probability that the prize probability increase state control circuit newly starts the prize probability increase state maintained for the predetermined period again from the beginning is increased. You.

In the probability changing means, the operating probability of the hit detection device during the set state of the winning probability increasing circuit is higher than when the winning probability increasing circuit is not in the set state, and is arbitrary within a range of 100% or less. , It is easy to predict the number of prize balls to be paid out in the state of forming the winning probability increasing state maintained for a predetermined period.

 Next, the operation will be described.

First, when there is no prize in any of the first and second starting winning ports 13, 14, 14, none of the latch circuits 96, 99 are latched, and the latch circuit 106 is not latched. Since H is input to the timer control circuit 116, the output of the timer circuit 110 is prohibited, and none of the solenoid 59, the demonstration LEDs 39, 39,..., And the lamps 22, 24 are driven.

On the other hand, since the latch circuit 104 is also not latched, the output signal from its output terminal is H, and the motor 69 is driven to rotate, so that the leaf display device 40 performs variable display of a picture.

Next, for example, when there is a prize in the first start winning port 13, the first
Since the start latch circuit 96 is latched, the AND circuit 114
Is input to the timer control circuit 116, L is input to the timer control circuit 116, the timer circuit 110 starts outputting, the solenoid 59 is excited, the guide vanes 34, 34 are opened, and the LEDs 39, 39,
..., 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 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 predetermined winning opening 26, nothing happens.

On the other hand, when there is a winning in the predetermined winning opening 26, the latch circuit
102 is latched, followed by a stop timing detection sensor 91
Since the latch circuit 104 is latched by the detection signal of
The output signal L from the output terminal causes the motor 69 to stop, and the picture on the leaf display 40 stops. At the same time, the hit detection sensor 50 determines whether the picture hits or misses. Thereafter, since the latch circuit 104 is reset by the self-reset circuit 124, the output signal from the output terminal thereof becomes H level.
Therefore, the motor 69 starts driving immediately after the stoppage.

When the picture is not judged, the latch circuit 106
Is not latched, the output signal of the AND circuit 114 is H
The output of the timer circuit 110 is prohibited and nothing happens.

On the other hand, if the picture is judged to be a hit, the latch circuit 106 is latched and starts a large role, and the output signal of the AND circuit 114 becomes L, so that the timer circuit 110 starts to output, and the solenoid 59 is excited. Guide vanes 34, 34 open, L
The EDs 39, 39, ... and the lamps 22, 24 are turned on. Further, since the count value of the continuation number counter circuit 128 becomes “1”, the LED 36-1 is turned on and the 10 count circuit 109 is turned on.
Gate to open, the count value is 10 count display
Displayed by 21. Further, during this time, a predetermined winning opening 26
When there is a prize, the latch circuit 144
Is latched, and the pattern stop of the leaf type display is performed, but is stored and held as a win only by winning a predetermined winning opening 26 regardless of the determination of the hit or miss. Therefore, the operating probability of the leaf display 40 is increased to 10/10 by the AND circuit 141 of the winning probability increasing circuit.

That is, during the set state of the winning probability increase circuits 106, 114, 116, 110, when the pachinko ball enters the predetermined winning opening 26 again,
After the end of the winning probability increase state during the predetermined period maintenance at that time, the winning probability increase state control circuits 142 to 7 newly start the winning probability increase state maintained for the predetermined period again from the beginning unconditionally, and maintain the predetermined period. The formation probability of the medium winning probability increase state is increased by a factor of three compared to the state before the winning probability increasing circuits 106, 114, 116, 110 are set. When the latch circuit 106 is reset, the latch circuit 106 is latched again, and the output signal of the AND circuit 114 becomes instantaneous H according to the output signal, and the timer circuit 110 returns to the initial state and starts outputting again from the beginning. Since the continuation number counter circuit 128 counts up by one with the signal, the LED 36-2 is also turned on in addition to the LED 36-1.

In this way, when the hand continues and the eighth time, the 8 count signal of the continuation number counter circuit 128 becomes H, and the input from the OR circuit 131 to the AND circuit 119 becomes L. Even if there is a win in the mouth 26, the motor 69 is not controlled to be stopped, so that all of the major roles are completed by 10 counts or 18 times of excitation of the solenoid 59.

In this embodiment, a leaf-type display is used to display information.However, this is a display of a well-known LED, a drum type in which various patterns are drawn on the outer surface of the drum, or the like. It may be displayed. Furthermore, three winning ports 26, 27, 27 are formed in the center role 10, but only one may be provided. Then, in this case, only one switch for detecting the pachinko ball corresponding to the winning opening may be attached, and may be used for both 10 count and continuous.

Further, in the above-described embodiment, the condition in which a large winning combination occurs is determined by winning the predetermined winning opening 26 and winning by determining the pattern, and after the large winning occurs, the winning is achieved only by winning the predetermined winning opening 26. In this way, the operating probability of the hit detection device before and after the occurrence of the large role is changed, but the present invention is not limited to this and may be as follows.

(B) Change the number of hits before and after the role. For example, one hit pattern is set before the large role occurs, and three hit patterns are set after the large role occurs.

(B) There will be one predetermined winning opening before the occurrence of the major role, and three after the occurrence of the major role. In this case, in the above embodiment, the present invention can be applied to a pachinko machine having no identification information display corresponding to the leaf display 40. In other words, this pachinko machine,
When the pachinko ball has won the predetermined winning opening, the winning probability of the winning device has started to be maintained within a predetermined time, and the pachinko ball has won the predetermined winning opening during the winning probability of the winning device. Sometimes, the winning probability increase state is started from the beginning again.

(C) The predetermined winning opening after the occurrence of the large role is mechanically made larger than before the occurrence of the large role. In this case, as in (b), the present invention can be applied to a pachinko machine without a display.

Furthermore, when a center role 10 having the same specification is provided in each of a plurality of pachinko machines and a game is played under the same conditions, a probability that a winning ball to the center role 10 will win a predetermined winning opening 26 and another winning opening 27. Theoretically should be almost the same between each pachinko machine, but due to machine differences caused by product accuracy, installation environment, etc., the value will be out of the allowable range and will vary between pachinko machines. May occur.

This variation is caused by the winning probability increase circuit 10 if the operating probability of the leaf-type display 40 is constant among the pachinko machines.
The operation rate of 6,114,116,110, and hence the difference in the number of prize balls paid out between pachinko machines per unit time exceeds the allowable range.

In such a case, the operating probability of the leaf-type indicator 40 during the set state of the winning probability increase circuits 106, 114, 116, and 110 is changed for each pachinko machine based on each of these ball count data, so that it is provided on the game board. The above-described difference in the number of dispensed items can be easily absorbed by a beginner technician and a skilled technician without making physical adjustments to the obstacle nail, the center accessory 10, or the periphery thereof.

(Effects of the Invention) As described above, according to the present invention, it is difficult to create a winning probability increased state, but once it is acquired, it is easy to continue and one winning probability increased state is ensured. Since it is performed for a predetermined period, it is hardly affected by machine differences as much as possible, it is possible to easily uniform the game operation of each gaming table, and a pachinko machine which is moderately taken from the viewpoint of improving game performance and eliminating gambling. Machine can be provided.

In addition, by creating a winning probability increase state that continues for a predetermined time,
When the number of winning balls to the winning device increases per unit time from the number of winning balls in the normal gaming state per unit time, thereby improving the game motivation, but when the winning probability increasing circuit is not in the set state by the probability changing means. Since the winning probability is increased more than the predetermined period, the winning probability increasing state maintained for a predetermined period is easily restarted, and the once-improved game motivation can be easily continued, so that a decrease in the game motivation can be suppressed.

In addition, due to machine differences caused by product accuracy, installation environment, etc., the operating rate of the winning probability increase circuit, and consequently the difference in the number of prize balls paid out between pachinko machines per unit time, may be within the allowable range. Even if it exceeds, by changing the operation probability of the hit detection device in the set state of the winning probability increase circuit for each pachinko machine based on each ball number data, the obstacle nail provided on the game board The above-mentioned difference in the number of payouts can be easily absorbed by novice engineers and skilled technicians without making physical adjustments at or around the prize awarding device. Can be improved.
