Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game control device for controlling a game state of a gaming machine, and more particularly to a game control device for determining a game state of a pachinko machine based on external random numbers. More specifically, the present invention relates to a game control device suitable for preventing an unexpected disadvantage from being given to a store manager due to misconduct or a breakdown, and a mounting structure thereof.

2. Description of the Related Art At present, various kinds of fraudulent activities are rampant in the pachinko industry, and methods for dealing with such fraudulent activities have been proposed. Examples of this misconduct include altering the ROM containing the game control program, malfunctioning the game machine by radio waves, and attaching special devices in the middle of wiring. A so-called dangling device used for improper installation of a special device on the way is difficult to find due to downsizing of the device, etc., and is easier to install than a modified ROM. One.

A typical hanging device includes a start winning opening switch for detecting that a game ball has won a starting winning opening,
A game control device for controlling a game state of a gaming machine, which is attached in the middle of wiring for connecting the game control device, and electrically detects a detection signal from a start winning opening switch so that the game control device generates a special prize state. Is to be delayed. This focuses on a process in which the game control device generates a special prize state. Generally, the game control device counts up by “1” sequentially from “0” at every predetermined operation clock (for example, 4 [ms]), and the count value becomes a maximum value (for example, “311”). "0" when exceeds
When the count value input in response to the detection signal from the starting winning opening switch becomes a big hit value (for example, "7"), a special prize state is generated. .

Therefore, the hanging device latches the detection signal from the starting winning opening switch by utilizing such a property of the gaming machine and synchronizes with the operation clock of the gaming control device, thereby reducing the count value of the jackpot lottery counter. The timing at which the jackpot value is reached is measured, and at that timing, the latched detection signal is output to the game control device.

[0005] Conventionally, as a device for dealing with fraudulent acts caused by a hanging device, for example, Japanese Patent Laid-Open No. 7-12 / 1995
Japanese Patent No. 4296 discloses a random number generation structure for a gaming machine. This means that even if a random number generator that generates random numbers independently of the operation clock of the game control device is provided as an external device of the game control device, and a hanging device is attached,
In the hanging device, the timing at which the random number used for the lottery for generating the special prize state becomes the big hit value cannot be measured.

[0006]

However, there are the following problems in controlling the gaming state of a gaming machine by applying the above-described conventional random number generation structure. In the above-described conventional random number generation structure, the random number generation device includes a pulse signal generation device that continuously generates a pulse signal of a predetermined frequency, and four cascade-connected 4-bit counters. The counter performs counting in response to the carry signal from the counter at the preceding stage, thereby generating a random number having a numerical range of 16 bits. On the other hand, in the game control device, normally, in order to generate a special prize state at a predetermined probability (for example, 1/312) using the 16-bit random number, a 16-bit numerical value range (“0” to “655”) is used.
It is considered that 206 jackpot values are set in the range up to 35 ").

Therefore, for example, if the signal line for outputting the carry signal of the first stage counter to the second stage counter is broken, the count values of all the second and subsequent counters are always "0". As a result, a random number having only a 4-bit numerical range is generated. Therefore, in such a case, if at least one big hit value is set in the 4-bit numerical range (the range from “0” to “15”) in the game control device, the probability of generating the special prize state is low. This is 1/16 or more, which means that a special prize state is generated with a very high probability.

For example, if the data signal line for outputting the count value of the first-stage counter corresponding to the least significant bit is disconnected, the least significant bit of the first-stage counter count value is always changed. It becomes “0”, and as a result, only a random number having an even value is generated. In the game control device, when the special prize state is generated, a lottery for generating the probability fluctuation state is performed following the end of the special prize state. Generally, in this lottery,
The probability of causing the probability fluctuation state is set to １ ／. Therefore, in such a case, in the game control device, if the probability variation state is generated when the input random number becomes an even value, if the special prize state is generated, the special prize state is generated. The probability fluctuation state will always occur after the end of the process.

The disconnection of the signal line may be caused not only by disconnection by a wrongdoer but also by a failure such as an initial failure of the gaming machine or aging deterioration. In any case, if the signal line is disconnected, A prize condition can be created with a very high probability, which can lead to unexpected disadvantages for store owners.

In addition to these problems, for example,
If the dangling device is modified so as to be synchronized with the pulse generation cycle of the random number generator instead of the operation clock of the game control device, the starting prize is performed at the timing when the random number used for the lottery for generating the special prize state becomes a big hit value. The detection signal from the mouth switch may be output to the game control device. Therefore, if such a dangling machine is attached to a game machine, it may not only provide unfair advantage to a fraudster, but also cause unexpected disadvantage to a store owner.

Accordingly, the present invention has been made in view of such unresolved problems of the conventional technology, and has provided an unexpected disadvantage to a store manager due to misconduct or breakdown. It is an object of the present invention to provide a game control device suitable for preventing giving and a mounting structure thereof.

[0012]

According to a first aspect of the present invention, there is provided a game control device comprising a game control means for controlling a game state of a game machine, wherein the game control means comprises: Inputting a random number from random number generation means for generating a random number independently of the operation of the game control means, and generating a predetermined game state when the input random number becomes a predetermined value; The value was set to a value other than the value of the random number generated by the random number generating means during the abnormal operation among the random number values generated by the random number generating means during the normal operation.

With such a configuration, during a normal operation, a random number is generated by the random number generation means independently of the operation of the game control means, and a random number is input from the random number generation means by the game control means. If the value of the input random number is a value other than the value of the random number generated by the random number generating means during the abnormal operation of the random number generated by the random number generating means during the normal operation, the predetermined gaming state Be raised.

On the other hand, at the time of abnormal operation, the game control means inputs a random number from the random number generating means. Since the value of this random number is that at the time of abnormal operation, the input random number is
The value of the random number generated by the random number generating means in the normal operation does not become a value other than the value of the random number generated by the random number generating means in the abnormal operation. Therefore, a predetermined game state is not generated.

Here, abnormal operation refers to an operation in which a specific value among random number values generated during normal operation is not generated due to fraud or failure. A state in which an action or a failure is likely to occur may be checked in advance and specified based on the result, or may be specified in real time according to the operation of the random number generation unit. Therefore, the predetermined value is, for example, to investigate abnormal operation in advance, register a random number value that does not occur during abnormal operation as a specific value, and set it as a fixed value other than the registered specific value. Alternatively, during the game control, a random number value that does not occur within a predetermined period may be regarded as a specific value, and may be variably set to a value other than the specific value. .

Further, the predetermined value may be set to one or more as long as it is a value other than the value of the random number generated by the random number generating means during the abnormal operation of the random number generated by the random number generating means during the normal operation. However, in order to cause a predetermined game state to occur with a predetermined probability, it is preferable to set a number corresponding to the predetermined probability.

The predetermined game state may be any state. Examples of the predetermined game state include a special state that is a game state advantageous to a player and a game state in which the special state is likely to occur. There is a certain probability fluctuation state. Further, "independently of the operation of the game control means" refers to an independent operation unrelated to the operation of the game control means, for example, an operation using an operation clock different from the operation clock of the game control means.

Further, in the game control device according to a second aspect of the present invention, in the game control device according to the first aspect, the random number generation unit generates a pulse signal of a predetermined frequency continuously. And a plurality of counters cascaded with a counter that counts cyclically in a predetermined numerical range according to the pulse signal as a first stage, wherein the game control means sets the count value of each counter to a predetermined rule. The random number is input as a random number, and the predetermined value is larger than a maximum count value that can be taken by at least the first-stage counter among random number values generated by the random number generation means during normal operation. Set to a large value.

With such a configuration, in the normal operation, the pulse signal of the predetermined frequency is continuously generated by the pulse signal generating means in the random number generating means,
The first-stage counter cyclically counts in a predetermined numerical range according to the pulse signal, and the other counters count cyclically in a predetermined numerical range in accordance with the count result of the previous-stage counter. Will be Then, a value obtained by adding the count values of the respective counters according to a predetermined rule is input as a random number by the game control means, and the input random number is at least the first-stage counter among the random number values generated by the random number generation means during normal operation. When the count value becomes larger than the maximum possible count value, a predetermined game state is generated.

On the other hand, for example, during an abnormal operation in which the signal line connecting the first-stage counter and the next-stage counter is disconnected due to fraud or failure, the count value of each counter is determined by the game control means according to a predetermined rule. The sum is input as a random number. Since the count values of all counters except the first stage are always “0”, the input random number is larger than the maximum count value that the first stage counter can take. Therefore, the predetermined game state is not generated.

Here, to count cyclically within a predetermined numerical range means that, for example, the count is incremented by "1" in order from "0", and the count value becomes the maximum value (for example, "255"). Means that the count value is circulated in the range from “0” to “255” by returning the count value to “0” when the count value is exceeded. In this case, conversely, the maximum value “25”
Count down from “5” to “1” in order.
When the count value exceeds the minimum value “0”, the count value may be returned to “255”.

Further, since the counters other than the first stage are cascade-connected, they count in a predetermined numerical range according to the count result of the previous stage counter. The counting is performed according to a carry signal output when the count value of the counter circulates beyond a predetermined numerical range.

In addition, the addition according to a predetermined rule means, for example,
This means multiplying the count value of each counter by a predetermined coefficient and adding it.When counters other than the first stage count according to the carry signal from the counter at the previous stage, random numbers with an appearance frequency of equal probability In order to obtain the value, it is preferable to use, as the predetermined coefficient to be multiplied by the count value of each counter, a value obtained by integrating values larger by “1” than the maximum value of the count values of all the counters in the preceding stage.

In the above description, an example of an abnormal operation in which the signal line connecting the first-stage counter and the next-stage counter is disconnected has been taken as an example. However, in a broader sense, the predetermined-stage counter and the next-stage counter are used. An abnormal operation in which the signal line connecting to the counter of (1) is disconnected may be considered. In order to prevent a predetermined gaming state from occurring even during such an abnormal operation, the predetermined value is set to the count value of the counter preceding the predetermined stage among the random numbers generated by the random number generating means during the normal operation. Is preferably set to a value larger than the maximum value obtained by adding the above according to the predetermined rule.

The invention according to claim 2 is particularly preferably applied to a lottery for generating a special prize state. Therefore, the predetermined gaming state cited in claim 1 is a special prize state. It is preferable that the game control means generate a special prize state when the input random number reaches a predetermined value.

According to a third aspect of the present invention, there is provided a game control device according to the first aspect, wherein the random number generation means generates a pulse signal of a predetermined frequency continuously. And a counter that counts cyclically in a predetermined numerical range according to the pulse signal, and outputs the count value of the counter as a random number, and converts the predetermined value to an odd value. Set.

With this configuration, during normal operation, the pulse signal of the predetermined frequency is continuously generated by the pulse signal generating means in the random number generating means,
The counter cyclically counts within a predetermined numerical range according to the pulse signal, and the count value of the counter is output as a random number. Then, a random number is input from the random number generation means by the game control means, and when the input random number becomes an odd value, a predetermined game state is generated.

On the other hand, for example, in the case of an abnormal operation in which a data signal line connecting the game control means and the random number generation means corresponding to the least significant bit is disconnected due to fraud or failure, the game control means , A random number is input from the random number generator, but since this random number is always an even value,
The input random number does not become an odd value, and therefore, a predetermined gaming state does not occur.

Here, to count cyclically within a predetermined numerical range is synonymous with the second aspect.
In addition, as described above, the present invention according to claim 3 is provided, for example, when a data signal line connecting the game control means and the random number generation means and corresponding to the least significant bit is disconnected, The game state is prevented from occurring. Therefore, in addition to such a configuration, for example,
Assuming that a data signal line connecting the game control means and the random number generation means which corresponds to a bit at a predetermined position is disconnected, the random number generation means may be a predetermined number. A pulse signal generating means for continuously generating a pulse signal of a frequency; and a counter for counting cyclically in a predetermined numerical range according to the pulse signal, and outputting a count value of the counter as a random number. A configuration is also conceivable in which the predetermined value is set to a value other than the value when the bit at the predetermined position of the count value is “0”.

The invention according to claim 3 is particularly preferably applied to a lottery for causing a probability fluctuation state. Therefore, the predetermined game state cited in claim 1 includes a probability fluctuation state. Preferably, the state is:
It is preferable that the game control means cause a probability fluctuation state to occur when the input random number reaches a predetermined value.

Further, in order to achieve the above object, a game control device according to a fourth aspect of the present invention includes a game control means for controlling a game state of a game machine, and the game control means comprises A random number is input from random number generating means for generating a random number in which a predetermined value appears in a first cycle independently of the operation of the means, and a predetermined game state is generated when the input random number reaches the predetermined value. The game control means further receives a timing signal from a timing signal generation means for generating a timing signal, and generates a random number in which the predetermined value appears in a second cycle different from the first cycle. The random number generating means is controlled according to the input timing signal so as to generate the random number.

With such a configuration, the random number generating means generates a random number in which a predetermined value appears in the first cycle independently of the operation of the game control means, and the game control means generates the random number. When a random number is input from the means and the input random number reaches a predetermined value, a predetermined game state is generated. However, when a timing signal is input from the timing signal generating means, the first cycle differs from the first cycle. Second
The random number generating means is controlled according to the input timing signal so as to generate a random number in which a predetermined value appears in the cycle of. As a result, a random number in which a predetermined value appears in the second cycle is generated by the random number generating means.

Here, the "predetermined game state" and "independently of the operation of the game control means" are synonymous with those of the first aspect. Further, in the game control device according to claim 5 of the present invention, in the game control device according to claim 4, the random number generation means includes a pulse signal generation means for continuously generating a pulse signal of a predetermined frequency; A counter that counts cyclically in a predetermined numerical range according to the pulse signal, and outputs the count value of the counter as a random number, the game control means,
The counter is reset according to the timing signal.

With such a configuration, in the random number generating means, the pulse signal of the predetermined frequency is continuously generated by the pulse signal generating means, and the counter cyclically generates a predetermined numerical range according to the pulse signal by the counter. And the count value of the counter is output as a random number.
Then, when the timing signal is input from the timing signal generating means by the game control means, the counter is reset according to the timing signal. As a result, in the random number generation means, the counter starts counting from the initial state in response to the reset, so that a random number in which a predetermined value appears in the second cycle is generated.

Here, performing counting cyclically within a predetermined numerical range is synonymous with the second aspect.
Further, the game control device according to claim 6 according to the present invention,
6. The game control device according to claim 1, wherein a plurality of the predetermined values are set over a predetermined numerical range.

With such a configuration, the game control means inputs a random number from the random number generation means, and when the input random number belongs to a predetermined numerical range, a predetermined game state is generated. For example, if the range of numbers that can be taken by the random number from the random number generation means is relatively large, it is necessary to set the predetermined value by a number corresponding to the size of the numerical range in order to generate a predetermined gaming state with a predetermined probability. is there. In such a case, if a predetermined value is set discretely in the numerical range, it must be determined whether or not the random number has reached the predetermined value for each predetermined value. According to the fifth aspect of the present invention, since a plurality of predetermined values are set over a predetermined numerical range, it is determined whether or not the random number has reached the predetermined value. Only the upper and lower limits need to be determined, and the required data capacity only needs to be in accordance with the upper and lower limits.

On the other hand, in order to achieve the above object, a game control device mounting structure according to claim 7 of the present invention mounts the game control device according to any one of claims 1 to 6 on the game machine. A substrate integrally provided with the game control means and the random number generation means is covered with a storage case, and the storage case is attached to the gaming machine.

With such a structure, since the game control means and the random number generation means are integrally covered by the storage case, it becomes difficult to attach a hanging device to the game control means or the random number generation means.

o) moves to step S206, adds “1” to the number of winning game balls, moves to step S208, inputs a random number from the random number generation device 300, and moves to step S210.

In step S210, the input random number is
The program is stored in a predetermined area of the RAM 240 corresponding to the number of winning game balls, and the process proceeds to step S212. This step S21
At 0, for example, if the number of winning game balls is “1”,
The input random number is stored in a predetermined area of the RAM 240 in the first area for storing the random number. Similarly, when the number of winning game balls is "2", the input random number is stored in the second area for storing the random number.

In step S212, the random number generator 30
By outputting a reset signal to 0, the counter 33
0, 332 is reset, and the process returns to step S110. On the other hand, when it is determined in step S204 that the number of winning game balls is four or more (Yes), the process returns to step S110.

Next, the symbol control process in step S112 will be described in detail with reference to FIGS. FIG. 7 is a flowchart showing the symbol control process.
FIG. 7 is a diagram showing a range of possible values of random numbers from the random number generator 300 on a circumference. Hereinafter, only the symbol control process of the special symbol display device 104 will be described, and description of the symbol control process of the ordinary symbol display device 106 will be omitted.

This symbol control processing is performed at a predetermined probability (for example,
As shown in FIG. 8, in order to generate a special prize state at 1/312), a range from “0” to “65535” that can be taken by the random number from the random number generation device 300 includes 206 jackpot values. The two numerical ranges are set at equal intervals, a random number is input from the random number generator 300 at the timing when the game ball wins in the starting winning opening 111, and a special prize state is generated when the input random number reaches a jackpot value. is there.

When the symbol control process is executed in step S112, as shown in FIG.
0, and determines whether or not the symbol displayed on the special symbol display device 104 is changing. If it is determined that the symbol is not changing (No), the process shifts to step S302 to win a prize. It is determined whether or not the number of game balls is one or more, and when it is determined that the number of winning game balls is one or more (Yes), the process proceeds to step S304.

In step S304, a random number is read from a predetermined area of the RAM 240 corresponding to the number of winning game balls, and the process proceeds to step S306, in which a symbol change start process for starting the change of the symbol displayed on the special symbol display device 104 is performed. Is performed, and it is determined whether the read random number belongs to the range from “447” to “516”, and when it is determined that the read random number belongs to this numerical range (Yes). Shifts to step S310. In step S308, specifically, it is determined whether the value of the read random number is equal to or less than the upper limit value “516”, and whether or not the read random number is equal to or greater than the lower limit value “447”. Is determined to be greater than or equal to the lower limit value, and is determined to belong to the numerical range. Hereinafter, the same applies to steps S324 and S326.

In step S310, it is determined whether or not the read random number is an odd value. If it is determined that the read random number is an odd value (Yes), the process proceeds to step S312 to generate a special prize state. At the same time, following the end of the special prize state, a high-probability transition symbol for causing a probability fluctuation state is determined, and the process proceeds to step S314. In this step S312, a symbol is determined, and a big hit flag indicating that a special prize state has occurred is set. Hereinafter, the same applies to step S322.

In step S314, a symbol variation stop process for stopping the symbol variably displayed on the special symbol display device 104 is performed so that the determined symbol is obtained, and the flow shifts to step S316 to determine the number of winning game balls. "1" is subtracted, and the process proceeds to step S318 to determine whether or not a jackpot is determined based on the jackpot flag. If it is determined that the jackpot is determined (Yes), the process proceeds to step S320 and the jackpot An electric accessory actuation process is performed to open the 115 in a predetermined pattern, and the process returns to step S104.

On the other hand, if it is determined in step S318 that it is not a jackpot (No), the process returns to step S104. On the other hand, when it is determined in step S310 that the read random number is not an odd value (No)
Proceeds to step S322 to determine a low-probability transition symbol for generating only the special prize state and returning to the normal state after the end of the special prize state, and then proceeds to step S314.

On the other hand, if it is determined in step S308 that the read random number does not belong to the range from "447" to "516" (No), the flow shifts to step S324 to set the read random number to " 25701 "to" 25
It is determined whether it belongs to the range up to 770 ", and when it is determined that it belongs to this numerical range (Yes), the process proceeds to step S310, but it is determined that it does not belong to this numerical range. If (No), the process moves to step S326.

In step S326, it is determined whether or not the read random number belongs to a range from "50956" to "51025". If it is determined that the random number belongs to this numerical range (Yes), the process proceeds to step S310. , But
When it is determined that it does not belong to this numerical range (No)
Shifts to step S328, determines a loss symbol for causing the normal state without generating the special prize state, and shifts to step S314.

On the other hand, when it is determined in step S302 that the number of winning game balls is not one or more (No), and when it is determined in step S300 that the symbol is changing (Yes), both cases are satisfied. It moves to step S318. Next, the operation of the above embodiment will be described with reference to FIGS. FIG. 9 is a time chart showing a cycle in which the value of the random number from the random number generation device 300 becomes the big hit value.

First, when the game machine is powered on and the game starts in the game machine, the random number generation device 300
The counter 33 according to the pulse signal from the transmission circuit 320
The count value of 0 is counted up sequentially from “0”, and a carry signal is output to the counter 332 at a timing when this count value exceeds “255” and returns to “0”. Then, in response to the carry signal, the count value of the counter 332 is incremented sequentially from “0”. Therefore, the CPU 220 can input a random number that is counted up cyclically in a range from “0” to “65535” according to the pulse signal from the transmission circuit 320.

On the other hand, when a game ball wins in the starting winning opening 111, a detection signal is output by the starting winning opening switch 131. In the CPU 220, the starting winning port switch 131
, A random number is input from the random number generation device 300 at substantially the same timing. At this time, as shown in FIG. 8, the inputted random numbers are in a range from “447” to “516”, and “25701” to “2577”.
0 ”and“ 50956 ”to“ 5102 ”.
If it belongs to any of the ranges up to 5 ", a symbol for generating the special prize state is displayed on the special symbol display device 104, and the special prize state is generated.

Further, at this time, when the input random number is an odd value, the high-probability transition symbol is displayed on the special symbol display device 1.
04, and after the end of the special prize state, a probability fluctuation state is generated subsequently. When the input random number is an even value, a low-probability transition symbol is displayed on the special symbol display device 104, and after the special prize state ends, the normal state is set.

When the input random number does not belong to any of the above numerical ranges, the lost symbol is displayed on the special symbol display device 104, and the normal state is continued. On the other hand, when a game ball wins in the starting winning opening 111, the CPU 2
At 20, the reset signal is output to the random number generation device 300 at almost the same timing, so that in the random number generation device 300, the count values of the counters 330 and 332 are both returned to “0”. Therefore, as shown in FIG. 9, the first cycle (65536/20 [MH]) is performed from the random number generation device 330 until a game ball wins in the starting winning opening 111.
z], i.e. 3.2768 [ms]) is a random number jackpot value by T ₁ appears is outputted, the game ball is the starting winning opening 111, a short second than the first cycle only the time A random number in which a jackpot value appears in the periods T ₂ and T ₃ is output. The second periods T ₂ and T ₃ have a range from 50 [ns] to 3.2768 [ms] depending on the timing at which the game ball wins the starting winning opening 111.

Now, in the state where the game control process is being executed, for example, due to cheating or failure, for example,
RCO terminal of counter 330 and CCK of counter 332
Assuming that the signal line connecting the terminal is disconnected, the count value of the counter 330 in the random number generation device 300 is “0”.
The counter 332 is incremented sequentially from
Remains at "0". Therefore, CPU
At 220, only random numbers that are counted up cyclically in the range from "0" to "255" can be input.

At the time of such an abnormal operation, the starting winning opening 111
, A random number is input from the random number generation device 300 at substantially the same timing, but since the value of the input random number can only take a range from “0” to “255”, the CPU 220 inputs the random number. The random number is "44
It does not belong to any of the range from "7" to "516", the range from "25701" to "25770", and the range from "50956" to "51025". As a result, the special prize state and the probability fluctuation state are not generated.

If the data signal line corresponding to the least significant bit among the data signal lines from the counter 330 connected to the data bus 262 is disconnected due to fraud or failure, the random number generator 300 ,
The count value of the counter 332 is incremented in order from “0”, but the least significant bit of the count value of the counter 330 is always output as “0”. Therefore, the CPU 220 can only input a random number having an even value.

At the time of such an abnormal operation, the starting winning opening 111
When the game ball wins, the CPU 220 inputs a random number from the random number generation device 300 at almost the same timing.
At this time, if the input random number belongs to any of the above numerical ranges, a prize state is generated, but since the input random number is an even value, even if the prize state is generated, it is always A low-probability transition symbol is displayed, and a probability fluctuation state is not generated.

Even during such an abnormal operation, as shown in FIG. 8, a plurality of jackpot values are set over a predetermined numerical range. The value is also almost halved, so that the probability that a prize state will occur hardly changes compared to the normal operation.

Even if a data signal line from the counter 330 connected to the data bus 262 other than the data signal line corresponding to the least significant bit is broken, the probability that the input random number will be an odd value and the even number Has no effect on the probability of becoming a value, the probability fluctuation state is generated at the expected probability (1/2).

As described above, according to the present embodiment, the jackpot value is determined by counting the value of the counter 330 from the random number value (range from “0” to “65535”) generated by the random number generation device 300 during normal operation. A value greater than the maximum value, ie, a range from “447” to “516”;
The range was set from "25701" to "25770" and the range from "50956" to "51025". Therefore, counter 330
When a signal line connecting the RCO terminal of the counter 332 and the CCK terminal of the counter 332 is disconnected, an award state and a probability variation state can be prevented from occurring.

Further, in the present embodiment, the judgment value for determining whether or not to cause the probability fluctuation state is set to an odd value. Therefore, data bus 26
In the abnormal operation in which the data signal line corresponding to the least significant bit among the data signal lines from the counter 330 connected to 2 is disconnected, it is possible to prevent the probability fluctuation state from occurring.

Further, in the present embodiment, the counter 330,
332 was reset. For this reason, even if a hanging device synchronized with the pulse generation cycle of the transmission circuit 320 is attached, the cycle in which the value of the random number becomes a big hit value shifts every time a game ball wins in the starting winning opening 111, so that in the hanging device, At the timing when the random number from the random number generation device 300 becomes the big hit value, the starting winning opening switch 1
It becomes difficult to output the detection signal from the CPU 31 to the CPU 220, and it is possible to prevent occurrence of the special prize state and the probability fluctuation state to some extent.

Further, in this embodiment, a plurality of jackpots are set over a predetermined numerical range. For this reason, compared to a configuration in which the jackpot value is discretely set in a range from “0” to “65535”, the random number generation device 300
It is only necessary to determine the upper and lower limits of the numerical range for which the jackpot value has been set, and to determine whether the random number from has become the jackpot value. What you need is sufficient. Therefore, as compared with such a configuration, it is possible to determine whether or not a jackpot is high speed, and it is possible to reduce the data capacity required for the determination.

Further, in the present embodiment, the main substrate 200
A substrate on which the random number generating device 300 is integrally provided is covered with a storage case 400, and both right and left sides of the storage case 400 are crimped with crimping tools 410 and 412 to be attached to the back of the game board. For this reason, in this state, the entire circumference of the main board 200 and the random number generator 300 is
00, the main board 200 and the random number generator 3 are not removed unless the caulking devices 410 and 412 are removed.
00 cannot be directly or indirectly touched. Therefore, it is possible to prevent the hanging device from being attached to the main board 200 or the random number generator 300 to some extent. Note that the storage case 400 may be attached to the back of the main body of the gaming machine.

In the above embodiment, the random number generator 300 is configured by cascading two 8-bit free running counters. However, the present invention is not limited to this.
As shown in FIG. 10, four 4-bit free-running counters may be connected in cascade. FIG.
FIG. 14 is a diagram showing another embodiment of the random number generation device 300.

That is, the random number generation device 300
As shown in FIG.
0 and four cascaded counters 340-34
6, and 6. The counter 340 is composed of a 4-bit free-running counter.
From the CCK terminal and counts up by “1” in order from “0” every time the pulse signal is input. When the count value exceeds “15”, the count value Is returned to "0" and a carry signal is output from the RCO terminal. When the detection signal from the start winning opening switch 131 is input to the RCK terminal, the current count value is latched into a built-in register (not shown), and when the reset signal from the CPU 220 is input from the CCLR terminal, the count value is forcibly reset. To "0".

The counters 342 to 346 are
0, the carry signal from the counter 340 to 344 in the preceding stage is input from the CCK terminal, and the detection signal from the start winning opening switch 131 is RCK.
Terminal, and a reset signal from the CPU 220
Input is made from the LR terminal.

In this case, unlike the above embodiment, a signal line connecting the RCO terminal of the counter 340 and the CCK terminal of the counter 342, a signal line connecting the RCO terminal of the counter 342 and the CCK terminal of the counter 344, Alternatively, the RCO terminal of the counter 344 and the CC of the counter 346
There is a possibility that the signal line connecting to the K terminal is disconnected. Therefore, in order to prevent a prize state and a probability variation state from occurring even when any signal line is disconnected, a signal line connecting the RCO terminal of the counter 344 and the CCK terminal of the counter 346 is used. The jackpot value may be set assuming that the is broken.

That is, the jackpot value is changed from “0” to “6”.
The counter 346 at the last stage in the range up to 5535 "
Is the minimum value, and the other counters 340
It is preferable to set a value larger than the value of the random number when the count value of ~ 344 is the maximum value, in this case, a value of "4096" or more. For example, “4096” to “416”
The jackpot value is set in the range from “5” to “29350” to “29419” and in the range from “54605” to “54674”.

Even with such a configuration, an effect equivalent to that of the above embodiment can be obtained. In particular, when the random number generator 300 is configured by cascading three or more counters in this way, the jackpot value is calculated by the counter of the last stage counter among the random numbers generated by the random number generator 300 during normal operation. If the value is set to a value smaller than the random number obtained when the value is set to the minimum value and the count value of the other counters is set to the maximum value, a carry signal from each counter is output due to fraud or failure. Therefore, even if any of the signal lines is disconnected, it is possible to reliably prevent a prize state and a probability fluctuation state from occurring. Therefore, in such a case, it is possible to further reduce the possibility of giving an unexpected disadvantage to the manager of the store due to fraud or breakdown.

In the above embodiment, the random number generator 300 is configured to generate a random number having a 16-bit numerical range. However, the present invention is not limited to this. May be configured to generate a random number having

In the above-described embodiment, the counter 3 is operated in accordance with the detection signal from the starting winning opening switch 131.
Although the configuration is such that the counters 30 and 332 are reset, it is more preferable that the timing at which the counters 330 and 332 are reset be more random. For example, in step S204, the number of winning game balls is four.
When it is determined that the above is true (Yes), the random number generator 3
By outputting a reset signal to the counter 33,
0, 332 may be reset, or the counters 330, 332 may be reset at the timing of generating the special prize state.

Further, in the above-described embodiment, the case where the game control program stored in the ROM 230 is executed before executing the processes shown in the flowcharts of FIGS. 5 to 7 has been described. The program is stored in the RAM 24 from a storage medium storing a program indicating these procedures.
0 may be read and executed.
