[0002]

2. Description of the Related Art In a pachinko machine in which a predetermined number of prize balls are paid out by winning a prize hole provided on a game board surface, a plurality of symbol display portions for variably displaying various predetermined symbols are displayed. When a game ball passes through a starting gate equipped with a ball detection device, each symbol display unit starts symbol variation based on a ball detection signal from the ball detection device,
There are various types of pachinko machines that are provided with a symbol display that stops and displays various combinations of symbols, and that, when each stop symbol of the symbol display is a predetermined combination, produces a predetermined profitable operation for the player. Proposed. As this profitable operation, a device for operating a condition device for opening a predetermined special winning opening (so-called three-type pachinko machine), or a device for directly opening the special winning opening (so-called 1).
Seed pachinko machine).

On the other hand, in order to manage the pitching of each pachinko machine, game data such as the number of out balls, the number of winning balls, the number of jackpots, etc. on the pachinko machine board is extracted, and based on the data,
There has also been proposed a configuration in which processing data such as a payout rate and a base value are calculated by a computer and output as management information of a pachinko machine.

[0004]

The pachinko machines have regulations based on the Law of the Arts, and in order to limit machines that are extremely intriguing, among the total number of prize balls obtained, the above-mentioned accessory is used to activate It is said that the number of prize balls to be played must not exceed 70% or 60% (60% if the accessory is operated continuously) in a test shooting test for 10 hours or more.

However, in recent years, amusement arcades that use pachinko machines that have been subjected to extreme nail adjustments such that prize balls cannot be obtained except for big hits have come to be seen. This situation not only touches the above regulations, but also incurs painful disadvantages for the players, and is against the ideal form of sound entertainment games, and for the players and the pachinko industry. This is not very desirable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pachinko machine having a configuration capable of drastically correcting the above-mentioned problems.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a prize ball total detecting means for detecting a total number of prize balls generated by winning at each prize port on the board, and a predetermined prize port (specification) on the board. A specific prize ball number detecting means for detecting the total number of specific prize balls generated by winning in the detecting port), a total prize ball number detected by the prize ball total number detecting means, and a detection by the specific prize ball number detecting means. The calculating means for calculating the ratio of the total number of specific prize balls to be calculated and comparing the calculated ratio with a predetermined limit ratio, and a notifying device for notifying an abnormality when the calculated ratio exceeds the limit ratio. It is characterized by having management means.

In this case, the ratio of the total number of specific prize balls to the total number of prize balls to each winning opening may be calculated instead of the ratio of the total number of specific prize balls to the total number of prize balls. At this time, if the number of winning balls for each winning opening is equal, it has the same meaning as the above-described configuration. Even if the number of prize balls differs for each winning opening, the approximate prize ball tendency can be grasped.

[0009] By the way, even if the number of obtained balls with respect to the number of shots fired is excessively small, the form of an appropriate recreation game is deviated. Therefore, in addition to the limit ratio (first limit ratio), hitting ball number detecting means for detecting the number of hitting balls is provided, and the number of hitting balls detected by the hitting ball number detecting means by the operation comparing means, and the total number of prize balls. The ratio with the total prize ball total detected by the detecting means is calculated and compared with a predetermined second limit ratio, and the notification means exceeds the first limit ratio and / or exceeds the second limit ratio. A throwing ball management means that informs the user of an abnormality in the event of a failure may be proposed.

Further, in each of the above configurations, it is possible to perform a comparison judgment with each limit ratio by the operation comparing means for each unit progress value. As this unit progress value, a unit set time at which the progress starts again when the time limit is exhausted can be used. In other words, after a predetermined time has elapsed, the ratio of the total number of specific prize balls and the total number of prize balls or the ratio of the total number of hit balls and the total number of prize balls accumulated during that time can be calculated and compared with the limit ratio. Then, after this calculation, the time period starts to advance again.

[0011] The unit progress value may be a unit set time that slides as time progresses, or a count value such as the number of unit hit balls that slide as count progresses.

Further, the number of hit balls referred to here means the actual number of hit balls including foul balls in a broad sense, and the effective number of hit balls minus the number of balls actually hit on the game board in a narrow sense. .

The predetermined winning port (specific detecting port) here includes not only a physically determined winning port but also a winning port specified at a specific time such as a big hit. .

[0014]

In the above-mentioned configuration, if the calculation ratio is less than the limit ratio, it is regarded as abnormal and a notification is issued. This announcement,
In addition to the case of notifying only to the game hall, a configuration for notifying the player is also proposed. Along with this notification, necessary measures such as providing game interrupting means and activating them are performed.

Further includes a winning ball from the electric won game 17,40, all winning ball is collected in a collection trough 37, ball detection is performed by the winning ball passage sensor S _6.

Next, the operation of the symbol display 4 will be described.

[0025] Each symbol display unit A~C, when ball detection signal is generated from the passing ball detection sensor S ₇ through the game ball to the starting gate 5, drives the symbol display device 4, according to a series of cyclic symbol row The display is sequentially changed.

In such a configuration, when a game ball is hit on the game board 1 and passes through the starting gate 5, a lottery is selected from the internal random numbers stored in the storage ROM connected to the central control unit MPU shown in FIG. And determine the hit or loss. Then, by determining the loss, the value at each time point is selected from the internal hit symbol random number or the internal loss symbol random number stored in the storage device ROM, and each symbol display section A, B, The stop symbol of C is determined.

Here, when the symbols on the symbol display section A and the symbol display section B match, a so-called reach state is established. In the case of the reach state, various fluctuation stop modes different from other stop modes are generated. In the case of a hit, the same symbol as the symbol display portions A and B appears on the symbol display portion C, and in the case of a loss, another symbol appears. In this case, the winning opening / closing device 10 performs a predetermined opening operation as described above, and the above-described winning operation is executed.

Next, the main part of the present invention will be described.

In the above-described configuration, the pachinko machine has a regulation based on the law of management, and in order to limit the machine that is extremely intriguing, the number of prize balls acquired by the operation of the accessory is calculated. It is said that the number of prize balls must not exceed 70% or 60% in a test shooting test for a certain time or more.

Therefore, in this pachinko machine, the total number of prize balls generated by winning in each winning port on the board surface and the identification generated by winning in a predetermined winning port (specific detecting ports 11 and 42). The payout management means that calculates the ratio with the total number of prize balls (= the total number of specific prize balls / the total number of prize balls), and when the ratio exceeds a predetermined limit ratio (exceeds the limit), determines that this is an abnormal ball management means. I have it.

Further, even when the number of obtained balls is excessively small relative to the number of shot balls fired, this is not a proper form of recreational game. Therefore, in this launching ball managing means, besides the limiting ratio (first limiting ratio), a hitting ball number detecting means for detecting the hitting ball number is provided, and the hitting number detecting means detects the hitting ball number by the operation comparing means. The calculated ratio between the number of hit balls and the total number of prize balls detected by the total prize ball detection means (= the total number of prize balls / the number of hit balls) is calculated and compared with a predetermined second limit ratio. I have to. Then, when the above-mentioned ratios exceed the first limit ratio and / or the second limit ratio, the notification unit notifies an abnormality.

That is, as shown in FIG. 5, this pachinko machine has a central control unit MP for performing various controls on a game board.
A microcomputer 50 having U is provided. The central control unit MPU performs various operation controls on the board, such as executing a control operation of various accessories and the like in a predetermined procedure, in order to perform a symbol operation control and to execute a jackpot. The ratio between the total number and the specific prize ball total is calculated, compared with a predetermined first limit ratio, and the ratio between the number of hit balls and the total prize ball total is calculated.
It has various functions such as a comparison operation function for comparing with the limit ratio of.

The central control unit MPU is connected to a storage device ROM for storing operation programs and a storage device RAM for reading and writing necessary data as needed. The storage device ROM stores fixed data such as a control program, a random number table, a big hit game pattern, a lamp, an LED display pattern, and a sound generation pattern from a speaker.

In the storage device RAM, symbol display units A, B,
A storage area for temporarily storing data and the like for determining the stop display mode of C, a register area forming a soft timer, a work area of the microcomputer 50, and the like are provided. This storage device RAM stores a control program instructing a unit progress value as a premise for comparing the actual ratio with the first and second limit ratios. The storage device RAM stores detection signals from the winning ball detection sensors S _{1 to} S ₄ , the ejected ball detecting sensor S ₅ , the winning ball passage sensor S ₆ , and the passing ball detection sensor S ₇ .

On the input side of the microcomputer 50,
Various switches such as the sensors S _{1 to} S ₇ are connected via a waveform shaping circuit for preventing chattering, and the discharged ball detection sensor S ₅ can also be directly connected.

On the output side, a driver circuit for receiving the output data and driving each of the above devices is connected, and the driver circuit includes each of the symbol display portions A, B,
C, various motors, LEDs, lamps and the like are connected. Furthermore, the central control unit MPU is connected to a sound generator that receives sound data and outputs the sound data to an amplifier connected to a speaker. The loudspeaker can constitute an embodiment of a notifying means described later. Moreover,
A firing motor or the like is connected to function as game interruption means.

In such a configuration, when the first calculation ratio exceeds the limit ratio (when the limit is exceeded) or / and when the second calculation ratio falls below the limit ratio (when the limit is exceeded). It is easy to use a liquid crystal display or a dot matrix display as the symbol display 4 as an operating notification means, and it is possible to display an error message using the entire surface.

The microcomputer 50 constitutes a part or all of the awarded ball total number detecting means, the specific awarded ball number detecting means, the hit ball number detecting means, and the notifying means according to the hit ball managing means of the present invention. In addition, the game interruption means is controlled.

The relationship with each means will be described more specifically.

The ball detection signals output from the winning ball detection sensors S _{1 to} S ₄ are input to the microcomputer 50. Then, the central control unit MPU adds the number of winning balls to each winning opening detected by the winning ball detecting sensors S _{1 to} S ₄ to the number of winning balls per one corresponding to the winning opening (award ball constant: 5 pieces). , 9, 12), and the sum is obtained to calculate the total number of prize balls. Therefore, the total prize ball detecting means includes the respective prize ball detection sensors S _{1 to} S ₄ , the central control unit MPU, and the storage device R for temporarily storing the integrated value.
It is configured by AM and the like.

As described above, the winning ball detection sensors S _{1 to} S ₄
The reason why is used is that it is possible to cope with a case where the number of award balls associated with each winning is different. Thus, the collection trough of winning ball passage of the machine base back surface is provided with a winning ball passage sensor S _6, if the winning balls number associated with each prize is the same, based on the winning ball passage sensor S ₆ award Calculation of the total number of balls can be performed.

The total number of specific prize balls is determined by the prize ball detection sensor S.
_3, it is possible calculation by multiplying the predetermined prize balls constant number winning ball by S _4. Therefore, the specific prize ball number detecting means includes the prize ball detection sensors S ₃ and S ₄ and the central controller M
It comprises a PU, a storage device RAM for temporarily storing the integrated value, and the like.

The hitting total is detected by integrating the ball detection signal of the exhaust ball detection sensor S ₅ provided in the discharge bulb passage out bulb with winning ball is discharged merged. Therefore, hitting speed detecting means includes a discharge bulb detection sensor S _5,
It is composed of a central control unit MPU for detecting the total number of hit balls by integrating the balls detected by the sensor, a storage device RAM, and the like.

As the number of hit balls, the number of hit balls is directly detected by a sensor S ₈ (see FIG. 1) provided on a launch ball guideway or the like, and the number of hit balls is detected by an integrated value thereof. Is also good.

In the central control unit MPU, a first limit ratio between the total number of prize balls and the total number of specific prize balls and a second limit ratio between the number of hit balls and the total number of prize balls are designated by a control program in advance. And stored in the storage device RAM. This limit ratio is a numerical value that determines whether or not the game can be continued, and is determined in consideration of the limit state of the game continuation. For example, the first limit ratio is set to 60 to 70%, and the second limit ratio is set to approximately 5 to 10%. Note that the value may be out of this range.

The control program includes a unit set time T
(Unit progress value) is also set. As the unit set time T, a relatively long span such as 5 hours to 10 hours is assumed. It should be noted that this time range may be exceeded or 5 hours or less.

Further, even if the unit set time T is not set, the data may be accumulated and continuously compared with the limit ratio. In this case, each data may be updated at the end of each game arcade. If the unit set time T (unit progress value) is not set in this way, the data may not be sufficiently accumulated and may be compared with the limit ratio to determine an abnormal state. It is necessary to determine an initial exclusion value, such as an initial standby time and an initial standby hit number, which are not compared with the above.

Next, the essential points of the operation of the present invention when the unit set time T is set will be described with reference to the flowchart of FIG.

The time period starts to progress (t in the figure is the current elapsed time)
Then, with the progress of the game, winning ball detection sensors S _{1 to} S
₄ and the discharge bulb detection sensor S ₅ and winning ball passage sensor S
The ball detection signal from ₆ is input to the central control unit MPU. In accordance with this, the specific total prize ball count, the total prize ball count, and the number of hit balls are respectively accumulated in the storage device RAM connected to the central control unit MPU based on the detection signals from the sensors S _{1 to} S ₆ . When the current elapsed time t has passed the unit set time T specified in advance, the central control device M
The PU calculates the ratio between the specific total number of prize balls and the total number of prize balls, and the ratio between the total number of prize balls and the number of hit balls.

It is to be noted that the start of the progress of the current elapsed time t is not limited to the start of the business of the game arcade, but may proceed on the assumption that the touch sensor of the start handle is turned on or the firing motor is driven. However, when there is no player, both the number of hit balls and the total number of prize balls are zero, and the calculation ratio is infinite. Therefore, such a case is controlled by program control to exclude such a case. The human detection means can be omitted.

After the above-described unit progress value has elapsed, the calculation ratio (= the total number of specific prize balls / the total number of prize balls) is compared with the first limit ratio, and if the calculation ratio does not exceed the limit ratio, Is determined to be normal, then the calculation ratio (= total prize ball count / hit ball count) is compared with the second limit ratio, and if the calculation ratio does not fall below the limit ratio, it is determined to be normal and the unit is determined. After the progress value has elapsed, the stored information is temporarily deleted, the time limit is restarted, and the storage is performed.

If any one of the above determinations is NO, the abnormality notification lamp connected to the output side of the microcomputer 50 is turned on, and further, the speaker is driven to perform the notification. Become. Further, the information may be displayed on a management monitor of the game arcade. That is, the microcomputer 50 and the abnormality notification lamp can constitute notification means relating to the ball-out management means of the present invention.

When an error message is displayed on the game board, the symbol display 4 may be displayed on the screen using a liquid crystal display or a dot matrix display as described above. .

The game interruption means may be driven together with this notification. As this means, it is possible to propose a configuration in which the game cannot be continued by stopping the launching ball or stopping the launching motor.

The platform in which the game cannot proceed is adjusted to an appropriate one by adjusting the nails during business hours or after closing the store so that the player can easily enter the entrance of the winning opening. Become.

In the above configuration, the unit progress value is
Although the unit set time T at which the progress is started again when the time limit is exhausted is used, the unit advance value may be the number of hit balls or the number of unit prize balls at which the advance is started again after the count is exhausted.

In the above arrangement, the ratio of the total number of specific prize balls to the total number of prize balls is detected, but the total number of prize balls to each prize port on the board is detected by the total prize ball detecting means. Then, when the unit progress value has expired, the ratio between the total number of specific winning balls and the total number of winning balls detected by the specific winning ball number detecting means is calculated and compared with a predetermined first limit ratio. You may do it. In this configuration, the specific winning ball number total detecting means is constituted by the winning ball detecting sensors S ₃ and S ₄ and the central control unit MPU which calculates the sum of the respective winning ball numbers. In this configuration, as long as the number of prize balls corresponding to each winning opening is the same, as described above, it has the same significance as the means of managing the ratio of the number of hit balls and the total number of prize balls. Even if the number of prize balls corresponding to each winning opening is different, an approximate tendency can be grasped.

On the other hand, as shown in FIG. 7, the unit progress value may be a unit set time T _{0 that} slides with time. In this case, the unit setting time T ₀ is divided by partitioning the time t _0, to ensure the address of the storage area of the storage device RAM corresponding to the number of said section time t _0, occurs in each segment time t ₀ The number of specific prize balls, the total number of prize balls and the number of hit balls are stored in each address. Then, as time progresses, the address storing the oldest information is sequentially rewritten with the latest information. Thus, from the information stored in each address, it is possible to always detect the output spheres state in the unit set time T ₀ which slides with time progress.

Further, the unit progress value may be set as the number of unit hit balls which slides as the counting progresses. In this case,
Addresses are set for each number of divisional hits that are appropriately divided into unit hits, the number of awarded balls and the number of specific winning balls corresponding to each number of hits are stored in each address, and the latest information is replaced with the oldest information. It is sufficient to sequentially calculate a predetermined ratio and compare it with the first limit ratio and / or the second limit ratio.

In the above-described ball management, in order to take into account the wave of the game, the abnormality determination is not performed only by one comparison result, but is performed, for example, three times in succession, when a predetermined limit ratio is exceeded. The determination may be made based on a total result of a plurality of results, such as a determination as abnormal. By doing so, there is an advantage that erroneous determination can be avoided when the unit progress value is reduced.

In the above configuration, the ratio between the total number of prize balls and the total number of specific prize balls is compared with the first limit ratio, and the ratio between the number of hit balls and the total number of prize balls is compared with the second limit ratio. However, only the ratio of the total prize ball total and the specific prize ball total may be compared with the limit ratio.

In the above-described embodiment, the present invention is applied to a so-called three-type pachinko machine which operates a condition device for opening a predetermined operation winning opening when each stop symbol of the symbol display is a predetermined combination. It shows the configuration, but it is applied to all pachinko machines such as the so-called one-type pachinko machine that directly opens the operation winning opening when each stop symbol of the symbol display is a predetermined combination. Can be.

Further, in each configuration, even if each ratio is processed by the reciprocal thereof (eg, processed by the total number of prize balls / the total number of specific prize balls instead of the specific number of prize balls / the total number of prize balls), the same significance is obtained. Having.

In the above-described configuration, the above-described specific detection ports 11 and 42 are designated as the specific detection ports. However, all winning ports related to the jackpot operation may be used as the specific detection ports. Further, the specific detection port may be specified not only by a physically determined winning port but also by a specific time such as a big hit.

The microcomputer 50 is connected to a microcomputer 51 (see FIG. 5) on the machine frame side for performing prize ball payout control and the like, and these microcomputers 50 and 51 work together or individually. A predetermined role is divided so as to constitute a part or all of the prize ball total number detecting means, the specific prize ball number detecting means, the hit ball number detecting means, the notification means, and the game interrupting means according to the ball managing means of the present invention. May be. In this case, it is conceivable to use the microcomputer 50 to share the first limit ratio and the microcomputer 51 to share the first limit ratio to perform the operation determination.

[0066]

According to the present invention, the ratio between the total number of prize balls and the total number of specific prize balls (or the total number of prize balls and the total number of specific prize balls) is calculated, and a predetermined limit ratio (first limit ratio) is calculated. ), The player will be notified of abnormalities, and will be able to take necessary measures such as stopping the game. It is possible to prevent an excessive adjustment of nails, which is an excellent effect of maintaining a healthy pachinko game.

Further, a ratio between the number of hit balls and the total prize ball total is calculated in a superimposed manner, and a predetermined second
In the configuration in which the limit ratio is compared with the limit ratio and the abnormality is notified even when the second limit ratio is exceeded,
A game mode in which the total number of prize balls acquired with respect to the number of shot balls fired is excessively small can be prevented, and there are excellent effects such as contributing to appropriate entertainment games.
