It is said that the number of prize balls to be awarded should not exceed approximately 70% or 60% (60% if the accessory continuously operates) in the test shooting test for 10 hours or more.

In recent years, however, it has become possible to find amusement halls operating with pachinko machines that have undergone extreme nail adjustment, such that prize balls cannot be obtained except for big hits. Such a situation not only touches the above-mentioned regulations, but also causes a painful disadvantage to the player, and is contrary to the ideal state of a healthy entertainment game. For the player and the pachinko industry as well. Not very good.

An object of the present invention is to provide a pachinko machine having a structure capable of drastically correcting the above-mentioned problems.

[0007]

According to the present invention, there is provided a total number of prize balls detecting means for detecting the total number of prize balls generated by winning a prize at each prize hole on the board, and a predetermined prize hole (specification on the board. Specific prize ball number detecting means for detecting the total number of specific prize balls generated by winning a prize in the detection opening), the total prize ball total number detected by the total prize ball detecting means, and the specific prize ball number detecting means. A calculated and comparing means for calculating the ratio of the cumulative total number of specified prize balls and comparing it with a predetermined limit ratio, and a notification means for notifying an abnormality when the calculated ratio exceeds the limit ratio. It is characterized by having a management means.

In this case, not the ratio of the total number of specific prize balls to the total number of prize balls, but the ratio of the total number of specific prize balls to the total number of prize balls to each winning opening may be calculated. At this time, if the number of prize balls for each winning port is equal, it has the same meaning as the above-mentioned configuration. Further, even if the number of prize balls for each winning opening is different, it is possible to grasp an approximate tendency of prize balls.

By the way, even when the number of balls obtained is extremely small with respect to the number of shots shot, the form of an amusement game is not appropriate. Therefore, in addition to the limit ratio (first limit ratio), a number-of-hits detection unit for detecting the number of hits is provided, and the number of hits detected by the number-of-hits detection unit by the calculation comparison unit and the total number of the award balls. The ratio of the total number of prize balls detected by the detection means is calculated and compared with a predetermined second limit ratio, and the notification means exceeds the first limit ratio and / or the second limit ratio. In the event of a failure, a means for managing the exit may be proposed.

Further, in each of the above constructions, the comparison judgment with each limit ratio may be made 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 is exhausted can be used. That is, after a lapse of a predetermined time, it is possible to calculate the ratio of the total of the specific prize balls and the total of the total prize balls or the total of the number of hit balls and the total of the total prize balls, which are accumulated during the predetermined time, and compare the calculated ratio with the limit ratio. Then, after this calculation, the time period starts to advance again.

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

Further, the number of hit balls as used herein means the actual number of hit balls including a foul ball in a broad sense, and the narrow number means an effective number of hit balls-that is, the number of balls actually hit on the game board surface. .

The predetermined winning opening (specific detection opening) mentioned here includes not only a physically defined winning opening but also a winning opening specified at a specific time such as during a big hit. .

[0014]

In the above configuration, if the calculation ratio is less than the limit ratio, it is considered to be abnormal and an alarm is issued. This notification is
In addition to the case of notifying only the game hall, a configuration of notifying the player is also proposed. Then, along with this notification, necessary measures such as providing a game interruption means and activating it will be taken.

The winning opening / closing device 10 is driven to open when the symbol display 4 hits and displays.

An electric accessory 17 is disposed below the operation winning port 11. The electric accessory 17 includes a rotating body 18 driven by a motor having six holes formed in the peripheral portion thereof, an operating hole 19 and a lower passage port 20, and the operating winning port 11
In response to the ball detection by the winning ball detection sensor S _{3 provided in the} (specific detection port), the hole is rotated right by one hole, and the winning balls can be sequentially stored in the hole. When three pieces are detected, or when the opening operation of the operation winning opening 11 by the winning opening opening / closing device 10 is completed, the rotation is constantly switched, and by this rotation operation, one ball is supplied to the operation hole 19 and the remainder is left. It flows out from the lower passage port 20 to the back side of the board, and each of them becomes a prize ball. When a sensor (not shown) is turned on by supplying a ball to the operation hole 19, a special operation state is set.

Below the electric accessory 17, a lower accessory 30 is disposed as shown in an enlarged view in FIG. A rotary chucker 31 in which a hole for one ball is formed in the peripheral portion is arranged above the lower accessory 30, and in the special operation state, a ball flows into the hole of the rotary chucker 31 to rotate the chucker. When balls are supplied to the chucker passage hole 32 as the ball 31 rotates, the winning ball detection sensor S _{1 of} the third-class starting opening
Thus, the winning is detected. As a result, the electric accessory 4 integrally formed with the rotary chucker 31.
The open / close blade 41 of 0 opens for 9.6 seconds (solid line position). A winning ball detection sensor S ₄ , which is a 10-count switch, is provided at the specific detection port 42 in the electric accessory 40. Then, by the winning ball detection sensor S ₄ , this electric accessory 40
When the inflow of about 10 balls is detected, the opening operation ends even during the opening operation. When 16 game balls are won in the rotary chucker 31, the special operation state is ended.

The arrangement of the above-mentioned respective sensors will be described with reference to FIG. 6. Each general winning opening 7 communicates with a predetermined winning ball discharging passage 35 on the back side of the board, and the discharging passage 35 has a winning ball detection sensor. S ₂ is arranged to detect winning balls, and as will be described later, 9 winning balls are generated for each winning ball. Also, the winning ball detection sensor S ₁ is turned on by the ball passing through the chucker passing hole 32, and five winning balls are generated for each winning ball. Further, all the winning balls including the winning balls from the electric accessory 17, 40 are collected in the collecting gutter 37, and the winning ball passage sensor S ₆ detects the balls.

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

When the game ball passes through the starting gate 5 and a ball detection signal is generated from the passing ball detection sensor S ₇ , each of the symbol display portions A to C drives the symbol display 4 and follows a series of circulating symbol strings. Change display sequentially.

In such a structure, 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 device ROM connected to the central control unit MPU shown in FIG. And decide whether to hit or lose. Then, by determining the hit, the value at each time point is selected from the internal hit symbol random number stored in the storage device ROM or the internal miss symbol random number, and each symbol display portion A, B, based on the content thereof. The stop design of C is determined.

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

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

In the above-mentioned configuration, the pachinko machine is regulated based on the wind management law, and in order to limit the machine that is extremely intriguing, the prize balls obtained from the accumulated prize balls are obtained by the operation of the winning character. It is said that the number of prize balls to be awarded should not exceed approximately 70% or 60% in the test shooting test for a certain time or longer.

Therefore, in this pachinko machine, the total of the total number of prize balls generated by winning the prize holes at the respective winning faces on the board and the identification generated by winning the prize holes (specific detection ports 11, 42) set in advance Calculate the ratio with the total number of prize balls (= accumulated specific number of prize balls / total number of prize balls), and if the ratio exceeds a predetermined limit ratio (exceeds the limit), a ball output management means that determines this as abnormal It has.

Furthermore, even if the number of balls to be acquired is excessively small with respect to the number of balls hit, it is not a proper form of entertainment game. In view of this, in this ball-out management means, in addition to such a limit ratio (first limit ratio), a number-of-hits detection unit for detecting the number of hits is provided, and the number of hits detection means is detected by the calculation comparison unit. The ratio of the total number of hit balls to the total number of prize balls detected by the total number of prize balls detecting means (= total number of prize balls / number of hit balls) is calculated and compared with a predetermined second limit ratio. I have to. Then, the notification means notifies the abnormality when each of the above-mentioned ratios exceeds the first limit ratio and / or the second limit ratio.

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

Further, the central control unit MPU is connected with a storage device ROM for storing an operation program and a storage device RAM capable of reading and writing necessary data at any time. The storage device ROM stores fixed data such as a control program, a random number table, a jackpot game pattern and a lamp, an LED display pattern, and a sound generation pattern from a speaker.

In the storage device RAM, the symbol display portions A, B,
A storage area for temporarily storing data etc. defining the stop display mode of C, a register area forming a soft timer, and a work area of the microcomputer 50 are provided. The storage device RAM stores a control program instructing a unit progress value, which is a premise for comparing the actual ratio with the first and second limit ratios. Moreover The memory RAM, winning ball detection sensor S ₁ to S _4, the detection signal from the discharge bulb detection sensor S _5, winning ball passage sensor S _6, passing ball detection sensor S ₇ is stored accumulated.

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

Further, on the output side, a driver circuit for receiving the output data and driving the respective devices is connected, and the driver circuits are connected to the respective symbol display parts A, B, and B of the symbol display unit 4.
C, various motors, LEDs, lamps, etc. are connected. Further, a sound generator that receives sound data and outputs the sound data to an amplifier connected to a speaker is connected to the central control unit MPU. This speaker can constitute an example of an informing means described later. Furthermore,
A firing motor or the like is connected to function as a game interruption means.

In such a configuration, when the first operation ratio exceeds the limit ratio (when the limit is exceeded), and / or when the second operation 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 the informing means to operate, and an error message can be displayed using the entire surface.

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

The relationship with each means will be described more specifically.

The ball detection signals output from the respective winning ball detection sensors S _{1 to} S ₄ are input to the microcomputer 50. The number of prize balls per prize hole detected by the prize winning ball detection sensors S _{1 to} S ₄ by the central control unit MPU is equal to the number of prize balls per unit corresponding to the prize hole (a prize ball constant: 5). , 9 pieces, 12 pieces), and the total sum is obtained to calculate the total number of prize balls. Thus, winning balls total number detecting means, each winning ball detection sensor S ₁ to S _4, the central control device MPU, a storage device for storing the accumulated value temporarily R
It will be composed of AM and the like.

In this way, the winning ball detection sensors S _{1 to} S ₄
The reason for using is that it is possible to deal with the case where the number of prize balls associated with each winning is different. Therefore, a winning ball passage sensor S ₆ is provided in the collecting trough of the winning ball passage on the back of the machine base, and if the number of prize balls associated with each winning is the same, the prize is based on this winning ball passage sensor S _6. It is possible to calculate the total number of balls.

The total number of specific winning balls is the winning ball detecting sensor S
_The calculation can be performed by multiplying the number of prize balls obtained in ₃ and S ₄ by a predetermined prize ball constant. Therefore, the specific prize ball number detecting means includes the prize winning ball detection sensors S ₃ and S ₄ and the central controller M.
It is configured by a PU, a storage device RAM for temporarily storing the integrated value, and the like.

The total number of hit balls is detected by integrating the ball detection signals of the discharged ball detection sensor S ₅ provided in the discharged ball passage in which the out ball and the winning ball join and are discharged. Therefore, the number of hit balls detecting means is the discharged ball detection sensor S ₅ ,
It is configured by a central control unit MPU that integrates the balls detected by the sensor and detects the total number of hit balls, a storage device RAM, and the like.

As the means for detecting the number of hit balls, the sensor S ₈ (see FIG. 1) provided in the launch ball guideway or the like is used to directly detect the hit balls, and the integrated value is used to detect the number of hit balls. 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 previously designated by the control program. 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 by planning the limit state of continuing the game. For example, the first limit rate is 60 to 70%, and the second limit rate is about 5 to 10%. It should be noted that it may be out of this range.

Further, 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. The 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 hall. If the unit set time T (unit progression value) is not set in this way, there is a possibility that an abnormality may be determined by comparing with the limit ratio while data is not being sufficiently accumulated. It is necessary to determine initial exclusion values such as the initial standby time and the number of initial standby hits that are not compared with.

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.

Time limit starts to progress (t in the figure is the current elapsed time)
However, as the game progresses, the winning ball detection sensors S _{1 to} S
₄ and discharge ball detection sensor S ₅ and winning ball passage sensor S
The ball detection signal from ₆ is input to the central control unit MPU. Along with this, the connected storage device RAM in the central control unit MPU, based on a detection signal from each sensor S ₁ to S _6, the specific prize ball number cumulative, winning balls accumulated number and the number of hitting are respectively integrated. When the current elapsed time t has passed the preset unit setting time T, the central controller M
The PU calculates the ratio of the total number of specific prize balls and the total number of prize balls, and the ratio of the total number of prize balls and the number of hit balls.

The progress of the current elapsed time t may be started on the assumption that the touch sensor on the start handle is turned on or the firing motor is driven, in addition to the start of business at the game hall. However, when there is no player, both the number of hit balls and the total number of prize balls become zero, and the calculation ratio becomes infinite. Therefore, by controlling the program so as to exclude such a case, It is possible to omit the person detecting means.

Then, after the above unit progress value has elapsed, the calculation ratio (= total number of specified prize balls / total number of prize balls) is compared with the first limit ratio, and when the calculation ratio does not exceed the limit ratio. Is determined to be normal, and then the calculation ratio (= total number of prize balls / number of hits) is compared with the second limit ratio. If the calculation ratio does not fall below the limit ratio, it is determined to be normal, and the unit After the lapse of the progress value, the stored information is once erased, the time limit is restarted, and the stored information is stored.

If any or all of the above judgments are NO, an abnormality notification lamp connected to the output side of the microcomputer 50 is turned on, or a speaker is driven to notify. Become. Further, it may be displayed on a management monitor in a game hall. That is, the microcomputer 50 and the abnormality notification lamp can constitute the notification means related to the ball-out management means of the present invention.

In the case of displaying an error message on the game board surface, the symbol display 4 may be displayed on the screen using a liquid crystal display or a dot matrix display as described above. .

In addition to this notification, the game interruption means may be driven. As this means, a configuration may be proposed in which the continuation of the game is disabled by stopping the sending of the firing ball, stopping the firing motor, or the like.

Then, the table in which the game cannot proceed in this way is made proper by adjusting the nails during business or after the store is closed so that the table 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 that starts the progress again when the time limit is exhausted is used, the unit progress value may be the number of unit hit balls or the number of unit award balls that start the progress again when the count is exhausted.

Further, in the above-mentioned configuration, the ratio of the total number of specific prize balls and the total number of prize balls is detected, but the total number of prize balls to each prize hole on the board is detected by the total number of prize balls detecting means. Then, when the unit progress value has expired, the ratio of 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. It may be done. In this structure, the specific winning sphere number cumulative detecting means is composed of the winning sphere detecting sensors S ₃ and S ₄ and the central control unit MPU for calculating the sum of the respective winning sphere numbers. In this configuration, if the number of prize balls corresponding to each winning opening is the same, it has the same meaning as the means for managing by the ratio of the number of hit balls and the cumulative number of prize balls as described above. Even if the number of prize balls corresponding to each winning opening is different, it is possible to grasp an approximate tendency.

On the other hand, the unit progress value may be set as a unit set time T _{0 that} slides as time progresses, as shown in FIG. 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. As a result, from the information stored in each address, it is possible to always detect the exit state at the unit set time T _{0 that} slides with the progress of time.

Furthermore, the unit progress value may be set as the number of unit hit balls that slide as the counting progresses. In this case,
An address is set for each divided number of hit balls obtained by appropriately dividing the number of hit balls, and the number of prize balls and the number of specific winning balls corresponding to each number of hit balls are stored in each address, and the latest information is replaced with the oldest information. While proceeding, the predetermined ratio may be sequentially calculated and compared with the first limit ratio and / or the second limit ratio.

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

In the above-mentioned configuration, the ratio of the total prize ball total and the specific prize ball total is compared with the first limit ratio, and the ratio of the number of hit balls and the total prize ball total is compared with the second limit ratio. However, it is also possible to compare only the ratio of the cumulative total of prize balls and the cumulative total of specific prize balls with the limit ratio.

Further, in the above-mentioned embodiment, when each stop symbol of the symbol display device is a predetermined combination, it is applied to a so-called three-kind pachinko machine which activates a condition device for opening a predetermined operation winning opening. Although the configuration is shown, when each stop symbol of the symbol display is a predetermined combination, it should be applied to all pachinko machines such as so-called type 1 pachinko machines that directly open the operation winning port You can

Further, in each configuration, even if each ratio is processed by the reciprocal thereof (eg; instead of specific prize balls / total prize balls, cumulative prize numbers / specific prize balls total is processed), the same meaning is obtained. Have.

Further, although the above-described specific detection ports 11 and 42 are designated as the specific detection ports in the above-described configuration, all the winning ports that are involved in the jackpot operation may be used as the specific detection ports. Furthermore, this specific detection opening may be specified not only at the physically determined winning opening but also at a specific time such as during a big hit.

In addition, a microcomputer 51 (see FIG. 5) on the machine frame side for performing prize ball payout control and the like is connected to the microcomputer 50. These microcomputers 50, 51 jointly or individually. By dividing a predetermined role, 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 informing means, and the game interruption means according to the ball discharge managing means of the present invention are configured. May be. In this case, it is conceivable that the microcomputer 50 shares the relationship of the first limit ratio and the microcomputer 51 shares the relationship of the first limit ratio for making the operation determination.

[0066]

According to the present invention, the ratio of the cumulative total of prize balls and the cumulative total of special prize balls (or the cumulative total of prize balls and the cumulative total of specific prize balls) is calculated to determine a predetermined limit ratio (first limit ratio). ), The player will be notified of any abnormalities and the necessary measures such as stopping the game can be taken.Therefore, unless the player hits a predetermined prize hole on the board, the ball will disappear in no time. There is an excellent effect that it is possible to prevent excessive nail adjustment that would otherwise occur, and to maintain a healthy pachinko game.

Further, the ratio of the number of hit balls and the cumulative total of the total number of prize balls is calculated by superimposing this, and a second predetermined value is calculated.
In a configuration in which an abnormality is notified even when the second limit ratio is exceeded,
There is an excellent effect that it is possible to prevent a game mode in which the total number of prize balls obtained with respect to the number of shots shot is excessively small, which contributes to an appropriate entertainment game.
