DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine in which a predetermined number of prize balls are paid out by winning a prize in a prize port provided on a game board.

[0002]

2. Description of the Related Art In order to manage the pitching of pachinko machines, game data such as the number of out balls, the number of winning balls, and the number of jackpots on the pachinko machine board is extracted, and based on the data, the payout rate,
There has been proposed a configuration in which processing data such as a base value is calculated by a computer and output as management information of a pachinko machine. Such management is merely to satisfy the management policy of the amusement arcade, and provides information for nail adjustment after the store is closed.

[0003]

Some pachinko machines have extremely low pitching rates (the number of awarded balls / the number of hit balls) and unilaterally disadvantageous customers. Particularly recently, machines that generate a big hit by the operation of the main character are mainstream, and in order to expect the big hit, customers tend to be patient and continue playing even in extremely low throwing conditions, as a result Frequently, customers lose too much money. Such a game state is against healthy entertainment and is not desirable not only for players but also for the pachinko industry. An object of the present invention is to provide a pachinko machine having a function of maintaining a proper gaming state.

[0004]

According to the present invention, there is provided a prize ball total number detecting means for detecting a total number of prize balls generated by winning each winning opening on a board, a hit number detecting means for detecting a hit number, Calculation and comparison for calculating the ratio of the number of hit balls detected by the hit ball number detecting means and the total number of prize balls detected by the prize ball total detecting means per unit progress value, and comparing the calculated ratio with a predetermined limit ratio A pachinko machine characterized by comprising a pitching control means comprising means and notification means for notifying an abnormality when the calculated ratio falls below a limit ratio.

[0005] In this case, instead of the ratio of the number of hit balls and the total number of prize balls, the ratio of the number of hit balls and the total of prize balls to each winning opening may be calculated. 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.

As the unit progress value, a unit set time at which the progress is started again when the time limit is exhausted can be used. That is, after the predetermined time has elapsed, the ratio of the number of hit balls accumulated during that time to the total number of prize balls or the total number of winning balls can be calculated and compared with the limit ratio. Then, after this calculation, the time period starts to advance again.

As the unit progress value, the number of hit balls which starts to progress again when the count is completed may be used. In this case, for example, when the number of hit balls hit on the game board reaches 1000, the calculation is performed and the comparison with the limit ratio is performed.

Further, the unit progress value may be a unit set time that slides as time progresses, or a unit hit ball number or a unit prize ball number that slides as count progresses.

Further, the number of hit balls as used herein may be the actual number of hit balls including foul balls, or the effective number of hit balls—that is, the number of hit balls actually hit on the game board. Included in the concept of number of hits.

[0010]

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

Then the winning ball detection sensor S _4, flows of about 10 balls to the electric won game 40 when it is detected, even during the opening operation, the opening operation is completed. When 16 game balls have won the rotating chucker 31, the special operation state ends.

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

[0020] 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 this configuration, when a game ball is hit on the game board 1 and passes through the starting gate 5, an internal game machine stored in a storage device built in the microcomputer 51 for controlling the game board shown in FIG. Lottery is drawn from random numbers to determine hits or losses. 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, C
To determine the stop symbol.

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.

This pachinko machine is provided with a payout management means for judging that a predetermined number of prize balls are not abnormal when a predetermined number of prize balls are not generated for the number of hit balls. Then, such means are awarded ball total number detecting means for detecting the total number of awarded balls generated by winning at each winning opening on the board, hitting number detecting means for detecting the number of hitting balls, and number of hitting balls per unit progress value Calculation comparing means for calculating the ratio between the number of hit balls detected by the detecting means and the total number of prize balls calculated by the total prize ball detecting means, and comparing the calculated ratio with a predetermined limit ratio; And a notification means for notifying an abnormality when the value falls below the threshold.

In order to realize each of these components, the pachinko machine is provided with a microcomputer 50 for back-setting for controlling the payout of prize balls and the like, which is provided with a central control unit MPU shown in FIG. Have been.

The central control unit MPU executes a control operation such as a prize ball and the like, and has a storage device ROM.
And a storage device RAM that can read and write necessary data at any time
Is connected.

In this storage device RAM, a payout number memory area storing the number of payout balls to be paid out for the signals from the respective winning ball detection sensors S _{1 to} S ₄ , and a prize ball instruction signal are added and subtracted. constituting counter area for storing, volume storing the detection signals from the winning ball passage sensor S ₆ in the priority order of processing defined in one by one prize ball dispensing apparatus 48 executes a program for instructing the execution of the payout, the soft timer Te A register area and a work area of the microcomputer 50 are provided. Also stored is a control program instructing a unit progress value that determines the timing at which the actual ratio is compared with the limit ratio. This storage device RAM
The ball detection signal output from the microcomputer 50 is also stored.

Further, the central control unit MPU has an address bus for unidirectionally transmitting information designating an address for reading and writing data from the central control unit MPU to the storage device RAM, a central control unit MPU, a storage device ROM, RA
M and a data bus for exchanging data are connected.

The microcomputer 50 having such a configuration includes a power supply circuit for supplying electricity to the central control unit MPU, a voltage detection circuit for transmitting a reset signal via an OR gate when the power supply voltage deviates from an allowable voltage value, and a clock. An oscillation circuit for generating a pulse, a frequency divider for dividing a clock pulse of the oscillation circuit, and transmitting a reset signal to a reset terminal via an OR gate are connected.

On the input side of the microcomputer 50,
Via a waveform shaping circuit for preventing chattering further microcomputer 51 and the discharge bulb detection sensor S ₅ for game board control, or the like winning ball passage sensor S ₆ provided in the winning ball path set trough 37 to be described later connected The signal sent from each device or switch is shaped by a waveform shaping circuit and transmitted to the central control unit MPU as input data. On the other hand, the microcomputer 5
Various switches such as a winning ball detection sensor S _{1 to} S ₄ and a passing ball detection sensor S ₇ are connected to the input side 1.

On the output side of the microcomputer 50, a driver circuit for receiving the output data and driving the above devices is connected, and a payout device 48, a firing motor, an abnormality notification lamp, a winning ball discharge solenoid, and the like are provided. I have.

The microcomputer 50 constitutes a part or all of the awarded ball total number detecting means, hitting ball number detecting means, arithmetic comparing means, and notifying means according to the hit ball managing means of the present invention, and controls the game interrupting means. I am trying to do it.

That is, each of the winning ball detection sensors S _{1 to} S
_The ball detection signal output from the microcomputer 51 connected to ₄ is input to the microcomputer 50. Then, multiplying by the central control unit MPU, a winning ball number for each winning opening detected by the winning ball detection sensor S ₁ to S _4, prize balls per one corresponding to the winning hole (the winning balls constant) Then, by calculating the sum, the total prize ball total is calculated. Therefore, the winning ball total number detecting means is constituted by the winning ball detecting sensors S _{1 to} S ₄ , the central control unit MPU, the storage device RAM for temporarily storing the integrated value, and the like.

The winning ball detection sensors S ₁ to S ₁
Was used S ₄ is to award counts associated with each prize is to be able to cope when different. Thus, the collection trough of winning ball passage of the machine base back surface and winning ball passage sensor S ₆ which are connected central control device MPU and directly provided, if the winning balls number associated with each prize are the same, the winning it is possible to calculation of prize balls total accumulated based on the ball passage sensor S _6.

A specific example of the prize ball management will be described with reference to FIG. 6. In each of the above-described configurations, as shown in FIG. 6, each of the general prize holes 7 is provided with a predetermined prize ball discharge path 35 on the back side of the board. communicates with, is detected exhaust Detchi 35 winning ball detection sensor S ₂ and is disposed winning ball, as will be described later, as nine winning balls for each winning ball is produced I have. Also, by passing the ball to the chucker passage hole 32,
Winning ball detection sensor S ₁ is turned on operation, five winning balls are to be generated for each winning ball. Moreover,
Including 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.

That is, the sensors S ₁ and S ₂ generate a signal for paying out a ball, and the signal is input to a microcomputer 51 for controlling a game board.
From 1, a prize ball instruction signal supporting the number of payouts is output to the microcomputer 50. Then, the microcomputer 51 according to the payout execution program,
By the detection signal from the winning ball passage sensor S _6, a one by one dispensing device 48, in response to the sensor S ₁ 5
Number and corresponding to the sensor S ₂ and instructs execution of nine prize balls paid out by the payout completion, the signal from the winning ball passage sensor S _6, the payout accumulated output from the sensor S _1, S ₂ Decrease the number. In this case, the processing is preferentially performed from the one with a small number of payouts.

On the other hand, the winning ball detection sensors S ₃ and S ₄
The microcomputer 50 does not participate in the payout control only by detecting the ball, and the microcomputer 50 has digested the number based on the sensors S ₁ and S _2, and the number of detection signals from the winning ball passage sensor S ₆ has not been exhausted. In that case, the difference is
It will be the number of winning balls from 7, 40, so 1 based on that number
The drive of the payout device 48 is controlled so that payouts are performed two by two. As a result, when a winning ball is generated by the operation of the electric accessory 17, 40, 12 winning balls are released for each winning ball.

In such a configuration, the total prize ball total is obtained by accumulating the respective prize ball constants (5, 9 or 12) for each occurrence of the prize balls detected by the sensors S _{1 to} S _4. To be detected. Therefore, the award ball total number detecting means can be constituted by the sensors S _{1 to} S ₄ and the microcomputer 51.

As another means, when a sensor for checking whether or not each prize ball payout operation has been correctly performed is provided on the payout device 48 side, the detection signal of the sensor is integrated. By doing so, the total prize ball total can be detected. In this case, the sensor constitutes a total prize ball detection means.

On the other hand, the number of ball hitting 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 sensor S _5, and thus is constituted by the central control device MPU and memory RAM for detecting a number of hitting by integrating the sensed sphere by the sensor. In addition, the number of hit balls can also be obtained by adding sensors that detect an out ball and a winning ball.

The number of hit balls is detected directly 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 the integrated value. Is also good.

Further, the operation comparing means is a central control unit MPU.
And a storage device RAM.

Next, the essential points of the operation of the present invention will be described with reference to the flowchart of FIG.

In the central control unit MPU, a unit set time T (unit progress value) is set in advance by a control program. The unit set time T is assumed to be 10 minutes or more and 1 hour or less. It should be noted that this time range may be exceeded, or 10 minutes or less.

Further, the limit ratio between the number of hit balls and the total prize ball total is 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 in consideration of the limit state of the game continuation. For example, in the case of a long unit set time T of 10 hours or more, the average value is set to a large value such as a limit ratio of 30%, but when the short unit set time T is used, the wave of the game is taken into consideration. Then, for example, about 5 to 10%.

Then, the time period starts (t in the figure is the current elapsed time), and as the game progresses, the winning ball detection sensor S
₁ ball detection signal to S ₄ is inputted via the microcomputer 51 to the central control device MPU, and the central control device MPU to the ball detection signal directly from the discharge bulb detection sensor S ₅ and winning ball passage sensor S ₆ Is input to Accordingly, the storage device R connected to the central control unit MPU
The number of hit balls and the total number of award balls are added to AM based on the detection signals from the sensors S _{1 to} S ₆ , respectively. Then, when the current elapsed time t exceeds the unit set time T specified in advance, the central control unit MPU calculates the ratio between the number of hit balls and the total number of award balls.

The progress of the current elapsed time t may proceed on the premise that the touch sensor of the steering wheel 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, by controlling the program so as to exclude such a case, such a person is eliminated. The detection means can be omitted.

After the elapse of the unit progress value, the calculated ratio is compared with the limit ratio. If the calculated ratio does not fall below the limit ratio, it is determined to be normal. The information is temporarily erased, the time period is restarted, and the storage is performed.

When the calculation ratio is lower than the limit ratio, the abnormality notification lamp connected to the output side of the microcomputer 50 is turned on, or the speaker is driven to notify. 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, a display capable of displaying a message is separately attached or another existing display (for example, game information such as the number of rounds is normally displayed). ) Can be used.

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 be advanced in this way is adjusted to an appropriate one by adjusting the nails during business hours or after the store is closed, so as to make it easier to enter the winning opening. Become.

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

In the above arrangement, the ratio between the number of hit balls and the 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, and the unit is determined. When the progress value has expired, the ratio between the number of hit balls detected by the hit ball number detection means and the total number of winning balls may be calculated and compared with a predetermined limit ratio. In the this configuration, winning ball total number detecting means winning ball passage sensor S ₆ (or winning ball detection sensor S ₁ ~
S ₄ ) and the central controller M for calculating the sum of the number of winning balls
It will be composed of PU. 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 by 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 awarded balls and the number of hit balls are stored in each address. Then, as time progresses, the address storing the oldest information is
Rewrite sequentially 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, as shown in FIG. 8, the unit progress value may be a unit winning ball number which slides as the counting progresses. In this case, the number of winning balls per unit is, for example, 10, and
In accordance with the number, the address of the storage area of the storage device RAM is secured, the number of hit balls from the winning ball until the next winning ball is generated is stored in each address, and when a new winning ball is generated, the last ball is generated. The address storing the number of hit balls from the winning ball to the winning ball is sequentially rewritten to the latest number of hit balls. As a result, the total number of hit balls stored at each address gives the number of unit winning balls sliding with time or the number of hit balls corresponding to the total prize ball total obtained by multiplying this by the prize ball constant.
Then, the unit winning ball count or the total prize ball total is calculated as a numerator, the hit ball count is calculated as a denominator, and the calculated ratio is compared with the limit ratio.

As a modified example, the number of hit balls which slides as the counting progresses may be used. In this case, an address is set for each number of divided hits obtained by appropriately dividing the unit hit number, the number of winning balls corresponding to each number of hits is stored in each address, and the latest information is replaced with the oldest information. It is only necessary to calculate the ratio sequentially and compare it with the limit ratio.

The calculation of the ratio of the number of hit balls detected by the hit ball number detecting means to the total number of prize balls or the number of winning balls per unit progress value and comparison with the limit ratio are performed by the microcomputer 50. Of the central control unit MPU. That is, as described above,
The central control unit MPU and the storage device RAM of the microcomputer 50 constitute an operation comparing means.

In the above-mentioned ball management, in order to take into account the wave of the game, instead of lowering the limit ratio or performing the abnormality determination based on only one comparison result, for example, the limit ratio is reduced three times in succession. Alternatively, the determination may be made based on a total result of a plurality of results, such as determining that an abnormality has occurred. By doing so, there is an advantage that erroneous determination can be avoided when the unit progress value is reduced.

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 special winning opening when each stop symbol of the symbol display is a predetermined combination. Although the configuration is shown, when each stop symbol of the symbol display is a predetermined combination, a so-called one-type pachinko machine that directly opens a special winning port or a so-called airplane stand (two-type pachinko) This can be applied to all pachinko machines.

[0061]

The present invention calculates the ratio of the total number of prize balls or the total number of winning balls to the number of hit balls per unit progress value,
When the ratio falls below a predetermined limit, the abnormality is notified and necessary measures such as stopping the game can be taken, so that the throwing rate is abnormally low and the hit ball is lost in no time. There is an excellent effect that excessive nail adjustment can be prevented and a healthy pachinko game can be maintained.
