Description

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 opening provided on a game board surface.

[0002]

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

[0003]

Depending on the pachinko machine, there is a platform that has an extremely poor ball output rate (number of prize balls / number of hit balls), and one-sidedly disadvantages the customer. Especially recently, machines that generate big hits by the action of accessory parts are the mainstream, and long-awaited big hits, so customers tend to endure playing games even in extremely low ball-out conditions, and as a result, Frequently, customers are overwhelmed. Such a game state is against healthy entertainment and is not preferable not only to the player but also to the pachinko industry. An object of the present invention is to provide a pachinko machine having a function capable of maintaining an appropriate gaming state.

[0004]

Means for Solving the Problems The present invention comprises a total number of award balls detecting means for detecting a total number of award balls generated by winning a prize in each prize hole on a board, and a number of hit balls detecting means for detecting a number of hit balls. Calculation comparison for calculating the ratio of the number of hit balls detected by the number of hit balls detection unit and the cumulative total of the total number of prize balls detected by the total number of prize balls detection unit per unit progress value, and comparing with a predetermined limit ratio A pachinko machine characterized in that it comprises a means for discharging a ball and a means for notifying an abnormality when the calculated ratio is below a limit ratio.

In this case, instead of the ratio of the number of hit balls and the cumulative total of prize balls, the ratio of the number of hit balls and the cumulative ratio 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.

As the unit progress value, a unit set time at which the progress starts again when the time limit is exhausted can be used. That is, after a lapse of a predetermined time, the ratio of the number of hit balls and the cumulative total of prize balls or the total prize 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, it is possible to use the number of hit balls that starts to proceed again when the counting is completed. In this case, for example, the calculation is performed when the number of hit balls hit on the play board surface reaches 1000, and the result is compared with the limit ratio.

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

Further, the number of hit balls referred to herein may be an actual number of hit balls including a foul ball, or an effective number of hit balls-that is, the number of hit balls actually hit on the game board surface, both of which are defined in the present invention. Included in the concept of the number of hits.

[0010]

In the above configuration, if the calculation rate per unit progress value is less than the limit rate, it is considered to be abnormal and a notification is given. This notification is proposed not only for notifying only the game hall but also for notifying the player. Then, along with this notification, necessary measures such as providing a game interruption means and activating it will be taken.

On the other hand, in the upper right part of the center case 3, as shown in an enlarged view in FIG. 2, a winning opening / closing device 10 is arranged, and the inside thereof is a special winning opening 11. The winning opening opening / closing device 10 is in a closed state (the chain line in FIG. 2) of the pair of opening / closing blades 12 and 12 and a closed position that shields the special winning opening 11 and an open state in which the pair of opening / closing blades 12 and 12 stands up (Fig. It is controlled by the solenoid for the normal electric accessory to the open position for guiding the game ball to the special winning opening 11 by the solid line (2). 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 special winning opening 11. The electric accessory 17 includes a rotating body 18 driven by a motor having six holes formed in its peripheral portion, an operating hole 19 and a lower passage opening 20, and the special winning opening 11
Corresponding to the ball detection by the winning ball detection sensor S ₃ arranged in, the hole is rotated right by one hole, and the winning balls can be sequentially stored in the hole, and three game balls are detected. At this time, or when the opening operation of the special winning opening 11 by the winning opening opening / closing device 10 is completed, the rotation is constantly switched, and by this rotating operation, one ball is supplied to the operating hole 19 and the remainder is supplied from the lower passage opening 20. It flows out to the back side of the board, and each 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 detecting sensor S ₄ which is a 10-count switch is arranged at the ball passing port 42 in the electric accessory 40. Then, when the winning ball detecting sensor S ₄ detects the inflow of about 10 balls into the electric accessory 40, the opening operation is completed even during the opening operation. When 16 game balls are won in the rotary chucker 31, the special operation state is ended.

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 parts 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 launched on the game board 1 and passes through the starting gate 5, the inside stored in the storage device built in the microcomputer 51 for controlling the game board shown in FIG. A lottery is selected from random numbers to determine whether to win or lose. Then, by this determination of 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 hit symbol random number, and each symbol display portion A, B, based on the content thereof. C
Determine the stop symbol.

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 main part of the present invention will be described.

In this pachinko machine, there is provided a payout management means for determining that the number of hit balls is abnormal if a predetermined cumulative number of prize balls is not generated. And, such means, the total number of prize balls detection means for detecting the total number of prize balls generated by winning a prize in each prize hole on the board, the number of hit balls detection means for detecting the number of hit balls, the number of hit balls per unit progress value The calculation comparison means for calculating the ratio of the number of hit balls detected by the detection means and the total number of prize balls calculated by the total number of prize balls detection means and comparing it with a predetermined limit ratio, and the calculated ratio is the limit ratio. And a notification means for notifying an abnormality when the temperature falls below the range.

In order to embody each of these configurations, the present pachinko machine is provided with a back set microcomputer 50 for controlling the payout of prize balls, which is provided with a central control unit MPU shown in FIG. Has been done.

Here, the central control unit MPU executes a control operation of prize balls and the like, and is 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 amount memory area for storing how many prize balls are paid out with respect to the signals from the respective winning ball detection sensors S _{1 to} S ₄ and a prize ball instruction signal are added and subtracted. A counter area for storing the information, a region for storing an execution program for instructing the prize-ball payout device 48 to execute the payout one by one in response to a detection signal from the prize-ball passage sensor S _{6 in} a predetermined priority processing order, and a soft timer are configured. 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 of comparing the actual ratio with the limit ratio. This storage device RAM
The sphere detection signal output from the microcomputer 50 is also stored in the memory.

Further, to the central control unit MPU, an address bus for unilaterally transmitting information designating an address for reading / writing data from the central control unit MPU to the storage unit RAM, the central control unit MPU and the storage unit ROM, RA
A data bus for exchanging data with M is 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 sending a reset signal via an OR gate when the power supply voltage deviates from an allowable voltage value, and a clock. An oscillator circuit that generates a pulse, a frequency divider that divides a clock pulse of the oscillator circuit, and sends a reset signal to a reset terminal through an OR gate is connected.

On the input side of the microcomputer 50,
A microcomputer 51 for controlling a game board, a discharge ball detection sensor S ₅ and a prize ball passage sensor S ₆ provided in a prize ball passage of a collecting gutter 37 which will be described later are connected through a waveform shaping circuit for preventing chattering. The signals sent from the respective devices or switches are shaped by the 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 winning ball detection sensors S _{1 to} S ₄ and passing ball detection sensor S ₇ are connected to the input side of ₁ .

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

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

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

As described above, the winning ball detecting sensors S _1-
The reason why S ₄ is used is to be able 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 directly connected to the central control unit MPU is provided in the collecting trough of the winning ball passage on the back of the machine base, and if the number of winning balls associated with each winning is the same, It is possible to calculate the total number of prize balls based on the ball passage sensor S ₆ .

A specific example of this prize ball management will be described with reference to FIG. 6. In each of the above-described configurations, each general winning opening 7 has a predetermined winning ball discharging passage 35 on the back side of the board. The winning ball detecting sensor S ₂ is provided in the discharge path 35 to detect the winning balls, and as will be described later, nine winning balls are generated for each winning ball. There is. Also, by passing the ball through the chucker passage hole 32,
The winning ball detection sensor S ₁ is activated to generate five winning balls for each winning ball. Furthermore,
All winning balls, including winning balls from the electric accessory 17, 40, are collected in the collecting gutter 37 and detected by the winning ball passage sensor S ₆ .

That is, the sensors S ₁ and S ₂ generate a ball payout signal, and the signal is input to the game board control microcomputer 51, and the microcomputer 5
From 1 to the microcomputer 50, the prize ball instruction signal for supporting the payout number is output. Then, the microcomputer 51, according to the payout execution program,
In response to the detection signal from the winning ball passage sensor S ₆ , the payout device 48 is provided one by one and the sensor 5 corresponding to the sensor S ₁
Instructing the execution of the payout of 9 prize balls corresponding to the individual and the sensor S ₂ , and upon completion of the payout, the payout integration output from the sensors S ₁ and S ₂ by the signal from the winning ball passage sensor S ₆ Reduce the number. In this case, the items with the smallest payout number are preferentially processed.

On the other hand, the winning ball detection sensors S ₃ and S ₄ are
Only the sphere is detected, and the microcomputer 50 does not participate in the payout control. The microcomputer 50 consumes 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 is not digested. In that case, the difference is the electric accessory 1
Since it is the number of winning balls from 7, 40, 1 based on that number
The payout device 48 is drive-controlled so as to pay out two by two. As a result, when prize balls are generated by the operation of the electric accessory 17, 40, 12 prize balls are discharged for each prize ball.

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

In addition, as another means, when a sensor for checking whether or not the individual prize ball payout operation is definitely performed is provided on the payout device 48 side, the detection signals of the sensor are integrated. Also by doing so, the total prize ball total can be detected, and in this case, the sensor constitutes the prize ball total detection means.

On the other hand, the 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 are discharged together. Therefore, the hitting ball number detecting means is composed of the sensor S ₅ , the central control unit MPU which integrates the balls detected by the sensor and detects the hitting ball number, the storage device RAM, and the like. In addition, the number of hit balls can also be obtained by adding together sensors that detect out balls and winning balls.

As the means for detecting the number of hit balls, the sensor S ₈ (see FIG. 1) provided on 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.

Further, the arithmetic comparison means is the 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.

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

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

Then, the time limit starts to progress (t in the figure is the current elapsed time), and as the game progresses, the winning ball detection sensor S
The ball detection signals _{1 to} S ₄ are input to the central control unit MPU via the microcomputer 51, and the ball detection signals from the discharge ball detection sensor S ₅ and the winning ball passage sensor S ₆ are directly input to the central control unit MPU. Entered in. Along with this, the storage device R connected to the central control unit MPU
The number of hit balls and the total number of prize balls are added to AM based on the detection signals from the sensors S _{1 to} S ₆ . Then, when the current elapsed time t has passed the preset unit setting time T, the central control unit MPU calculates a ratio of the number of hit balls and the total number of prize balls.

The progress of the current elapsed time t may be performed on the assumption that the touch sensor of the steering wheel is turned on or the firing motor is driven. However, when there are no players, 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 to exclude such cases, It is possible to omit the detection means.

Then, after the unit progress value has elapsed, the calculation ratio is compared with the limit ratio. If the calculation ratio does not fall below the limit ratio, it is judged to be normal, and after the unit progress value has elapsed, the memory is stored. The information is once erased, the time period is restarted, and storage and accumulation are performed.

When the calculation ratio falls below the limit ratio, an abnormality notification lamp connected to the output side of the microcomputer 50 is turned on, or a speaker is driven to notify. 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, 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). Stuff).

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 be progressed 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 advancement value may be a predetermined number of hit balls that starts the progress again when the count is exhausted.

Further, in the above configuration, 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 hole on the board is detected by the total number of prize balls detection unit, and the unit At the time when the progress value has expired, the ratio of 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 this configuration, the winning ball total number detecting means is the winning ball passage sensor S ₆ (or the winning ball detection sensors S ₁ to
S ₄ ) and the central control unit M for calculating the sum of the number of winning balls
It will be configured by PU. 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 total 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 which} 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 prize balls and the number of hit balls are stored in each address. And with the progress of time, the address storing the oldest information,
It is 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.

Further, as shown in FIG. 8, the unit progress value may be the number of unit winning balls that slides with the progress of counting. In this case, the number of unit winning balls is, for example, 10,
The address of the storage area of the storage device RAM is secured corresponding to the number, and the number of hit balls from the winning ball to the next winning ball is stored in each address, and when a new winning ball occurs, the last part 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. Thus, the total number of hit balls stored in each address gives the number of hit balls that slides over time or the number of hit balls corresponding to the cumulative total number of prize balls obtained by multiplying this by the prize ball constant.
Then, the number of unit winning balls or the total number of winning balls is calculated as the numerator, and the number of hit balls is calculated as the denominator to compare with the limit ratio.

As a modification of this, the number of unit hit balls that slides as the counting progresses may be used. In this case, an address is set for each divided number of hit balls by dividing the number of hit balls appropriately, and the number of winning balls corresponding to each number of hit balls is stored in each address, and the latest information is replaced with the oldest information. While proceeding, the ratio may be sequentially calculated and compared with the limit ratio.

The microcomputer 50 calculates the ratio of the number of hit balls detected by the number of hit balls detection means and the cumulative total of prize balls or the number of prize balls per each unit progress value and compares the limit ratio. The central control unit MPU of FIG. That is, as mentioned above,
The central control unit MPU of the microcomputer 50 and the memory RAM form an arithmetic comparison unit.

In the above-mentioned ball management, in order to consider the wave of the game, the limit rate is not lowered or the abnormality judgment is not made only by the result of one comparison, but the limit rate is, for example, three times in succession. The determination may be made based on a comprehensive result of a plurality of results, such as a determination 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.

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-type pachinko machine which operates a condition device for opening a predetermined special winning opening. Although the structure is shown, when each stop symbol of the symbol display is a predetermined combination, a so-called type 1 pachinko machine or a so-called airplane platform (type 2 pachinko machine) in which the special winning opening is directly opened Machine) and all other pachinko machines.

[0061]

The present invention calculates the ratio of the total number of prize balls or the total number of prize balls and the number of hit balls per unit progress value,
It is designed to notify you of an abnormality when it falls below a predetermined limit rate, so that you can take necessary measures such as stopping the game, so the rate of launch is abnormally low, and it seems that the hit ball disappears in no time. There is an excellent effect that it is possible to prevent excessive nail adjustment and maintain a healthy pachinko game.
