Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko gaming machine, and more specifically, a sensor detects whether or not a gaming medium such as a gaming ball has passed a predetermined area, and a game is played according to the detection result. The present invention relates to a gaming machine adapted to progress.

[0002]

2. Description of the Related Art Conventionally, for example, a main controller and a sub-controller are used, and a plurality of symbol strings (for example, left, middle, and right symbol strings) are variably displayed and stopped on a display incorporated in a game board, There is known a pachinko gaming machine that generates a jackpot gaming state that is advantageous to the player based on the variation stop mode and the like. In this pachinko gaming machine, a sensor (starting port switch) detects the winning of the game ball at the starting port. The start port switch transmits a signal having a different voltage when the game ball is not passed and when it is passed, for example, a signal having a higher voltage when the game ball is passed than when it is not passed, by one signal line. The main control unit, when the voltage of the transmitted signal is higher than a predetermined value, determines that the game ball has won the starting opening and performs a lottery,
A display command related to the combination of the symbol variation time and the variation stop symbol is transmitted to the sub control device.

When the sub-control device receives the display command, it operates the display according to the symbol variation time and the variation stop symbol indicated by the display command. After starting the fluctuations of all the symbol rows at once, for example, the fluctuations of the symbol rows are continuously stopped in the order of left, right, and middle. Alternatively, after starting the fluctuation of all the symbol rows, the fluctuation of the symbol rows is stopped in the order of left and right, and the fluctuation of the middle symbol row is stopped after the reach effect is passed. Then, if the combination of the variable stop symbols of all the symbol rows is a predetermined combination of big hits, a big winning game state in which more prize balls can be obtained, such as opening the special winning opening, is generated. . Various sensors are used in the pachinko gaming machine in addition to the switch for the starting opening, and the progress of the game is changed depending on the detection result of the game ball by the sensor.

[0004]

However, in the pachinko gaming machine described above, electromagnetic waves generated from surrounding electronic devices may be superimposed on signals transmitted through signal lines of various sensors as electromagnetic noise (normal mode noise). is there. In addition, some players are so-called radio wave gotos who use devices such as transceivers to intentionally generate electromagnetic waves and illegally superimpose electromagnetic noise on the signals of various sensors. Then, when the electromagnetic noise is superimposed, the same signal as that at the time of winning is transmitted through the signal line of the sensor even though the game ball has not won at the starting opening or the like.
The main controller treats this signal as a signal accompanying the passage of the game ball and advances the game. In an extreme case, when the electromagnetic wave is generated in synchronization with the cycle in which the big hit game state occurs, the big hit game state may occur with a high probability.

Therefore, an object of the present invention is to eliminate the influence of electromagnetic noise and prevent malfunctions even if electromagnetic noise is superimposed on the signal of a sensor that detects the passage of a game medium such as a game ball. It is to provide a game machine.

[Means for Solving the Problems] Effective means for solving the above problems will be described below. The operation and the like will be described as needed.

Means 1. In a gaming machine configured to detect a passing state of a game medium in a predetermined area by a game medium detecting unit and to advance a game according to the detection result, the game medium detecting unit determines whether the game medium has passed or not. According to the second signal, the first signal having a different voltage is transmitted through the first signal line, and the respective voltages when the game medium passes and when the game medium does not pass are opposite to the respective voltages of the first signal. The second
A signal transmission means for transmitting by a signal line, and a detection determination means for determining whether or not the game medium has passed the predetermined area based on a difference between both voltages of the first signal and the second signal by the signal transmission means. A game machine characterized by being provided.

According to the means 1, the passing condition of the game medium in the predetermined area is detected by the game medium detecting means.
Upon this detection, the signal transmission means transmits the first signal through the first signal line and the second signal through the second signal line. In the first signal, the voltage when the game medium passes and the voltage when the game medium does not pass are different from each other. In the second signal, the voltage when the game medium passes becomes the same as the voltage of the first signal when the game medium does not pass, and the voltage when the game medium does not pass becomes the voltage of the first signal when the game medium passes. It will be the same as the voltage. Here, in each signal, the difference (absolute value) between the voltage when the game medium passes and the voltage when the game medium does not pass is defined as α. Then, if the voltage difference between both signals when the game medium passes is α, the voltage difference when the game medium does not pass becomes −α.

On the other hand, when electromagnetic noise is similarly superimposed on the first signal and the second signal, the voltage of each signal becomes higher (or lower) by the voltage of the electromagnetic noise, and the waveforms of both signals become , The waveform is different from the waveform when electromagnetic noise is not superimposed. However, the voltage difference between both signals when the game medium passes is α, and the voltage difference between both signals when the game medium does not pass is −α. This relationship holds as long as the voltage of the electromagnetic noise superimposed on the first signal and the voltage of the electromagnetic noise superimposed on the second signal are the same. Thus, even if electromagnetic noise is superposed, the voltage difference between the two signals is not affected by the superposition.

On the other hand, the detection determining means determines whether or not the game medium has passed the predetermined area based on the difference between the voltages of the first signal and the second signal. As described above, as long as the difference between the voltages of both signals is not affected by the superposition of electromagnetic noise, the determination result of this detection determination means is the same whether the electromagnetic noise is superposed or not. Therefore, in the gaming machine, each part operates according to the detection result of the game medium detection means to proceed with the game. Even if electromagnetic noise is superimposed on each part, the same operation is performed as when no noise is superimposed. To do. There is no fear of malfunction due to electromagnetic noise.

Means 2. In the means 1, the first signal line and the second signal line are arranged close to each other, the gaming machine.

According to the means 2, when an electromagnetic wave is generated from the electromagnetic wave generation source and the first signal line and the second signal line are separated from each other, the electromagnetic wave is superposed only on the signal of one signal line as electromagnetic noise. However, if both signal lines are close to each other, it is easy to superimpose the signals on both signal lines. Since electromagnetic noise of the same voltage is likely to be superimposed on the first signal and the second signal, the difference between the voltages of both signals is less likely to be affected by the superposition. Therefore, the determination result of the detection determination means is surely the same when the electromagnetic noise is superposed and when it is not superposed.

Means 3. In the means 2, the first signal line and the second signal line are twisted with each other to form a twisted pair line, the gaming machine.

According to the means 3, the first signal line and the second signal line
When the signal lines are twisted with each other to form a twisted pair line, they are closely attached and integrated. Therefore, when an electromagnetic wave is generated from the electromagnetic wave generation source in the vicinity of the twisted pair wire, it becomes easier to superimpose it on the signal of both signal lines as electromagnetic noise of the same voltage as compared with the case where both signal lines are simply close to each other. .

Means 4. In a gaming machine configured to detect a passing state of a game medium in a predetermined area by a game medium detecting unit and to advance a game according to the detection result, the game medium detecting unit determines whether the game medium has passed or not. According to the second signal, the first signal having a different voltage is transmitted through the first signal line, and the respective voltages when the game medium passes and when the game medium does not pass are opposite to the respective voltages of the first signal. The second
Regarding the signal transmission means for transmitting by the signal line and the signal, the absolute value of the difference between the voltage when the game medium passes and the voltage when the game medium does not pass is set to a predetermined value, and the difference between the voltages of both signals by the signal transmission means A game machine comprising: validity determining means for determining both signals as invalid when an absolute value is different from the predetermined value.

According to the means 4, the passing condition of the game medium in the predetermined area is detected by the game medium detecting means.
Upon this detection, the signal transmission means transmits the first signal through the first signal line and the second signal through the second signal line. In the first signal, the voltage when the game medium passes and the voltage when the game medium does not pass are different from each other. In the second signal, the voltage when the game medium passes becomes the same as the voltage of the first signal when the game medium does not pass, and the voltage when the game medium does not pass becomes the voltage of the first signal when the game medium passes. It will be the same as the voltage. Here, in each signal, the difference (absolute value) between the voltage when the game medium passes and the voltage when the game medium does not pass is defined as α. Then, if the voltage difference between both signals when the game medium passes is α, the voltage difference when the game medium does not pass becomes −α. The absolute value of the voltage difference is the same value α regardless of whether or not the game medium has passed.

On the other hand, when the electromagnetic noise is superimposed only on the first signal, the absolute value of the voltage difference becomes a value different from the absolute value when the electromagnetic noise is not superimposed. This can be said whether the game medium passes through the signal transmission means or not. Similarly, when electromagnetic noise is superimposed only on the second signal, the absolute value of the voltage difference is different from the absolute value when electromagnetic noise is not superimposed, regardless of whether or not the game medium has passed. This relationship holds as long as electromagnetic noise is superimposed on only one signal.

On the other hand, the validity determining means compares the absolute value of the voltage difference between the two signals with a predetermined value. This predetermined value is
In each signal, it is the difference (absolute value) between the voltage when the game medium passes and the voltage when the game medium does not pass. And
When the absolute value matches the predetermined value, both signals are determined to be valid, and when they do not match, the signal is determined to be invalid. Thus, based on the relationship between the absolute value of the difference between the two voltages and the predetermined value, a signal with electromagnetic noise superimposed,
A distinction is made from non-overlapping signals. Then, a signal determined to be valid (a signal on which electromagnetic noise is not superimposed) is used for progress of the game, and a signal determined to be invalid (a signal on which electromagnetic noise is superimposed) must be used for progress of the game. For example, even if electromagnetic noise is superimposed, there is no risk of malfunction due to the electromagnetic noise.

Means 5. The means 4 further comprises passage determining means for determining whether or not the game medium has passed based on at least one of the first signal and the second signal in response to the validity determination by the validity determining means. And a gaming machine.

According to the means 5, when the absolute value of the difference between the two voltages is the predetermined value, the first signal and the second signal from the game medium detecting means are signals without superposition of electromagnetic noise. The validity is judged by the validity judging means. In this case, the passage determining means determines whether or not the game medium has passed based on at least one of the first signal and the second signal. Then, the game is advanced according to the content of the determination, that is, the passing situation of the game medium with respect to the predetermined area.

Means 6. The means 4 or 5 further includes non-passage determining means for determining non-passage of the game medium with respect to the predetermined area according to the invalidity determination by the validity determining means.

According to the means 6, when the absolute value of the difference between the two voltages is different from the predetermined value and the validity determining means determines that the signal is invalid, the non-passage determining means determines
It is determined that the game medium has not passed the predetermined area. Then, the game is advanced according to the content of the decision. Therefore, if the electromagnetic noise is superimposed only on one of the signals, even if the game medium passes through the predetermined area at that time, the situation advantageous to the player does not occur.

Means 7. In any one of the means 1 to 3, based on the lottery means for conducting a lottery on the condition that the predetermined area passage of the game medium by the game medium detecting means is detected, and the lottery by the lottery means being a win, A gaming machine further comprising special game state generation means for generating a special game state advantageous to a player.

According to the means 7, when the game medium detecting means detects that the game medium has passed the predetermined area, the lottery means carries out a lottery. If the result of the lottery is a win, the special game state generation means generates a special game state advantageous to the player. Here, as described above, the detection result of the game medium detection means is the same when the electromagnetic noise is superposed and when it is not superposed, so that the game medium does not pass through the predetermined area, There is no lottery due to the superposition of electromagnetic noise, and there is no special gaming state associated with it.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) Hereinafter, a first embodiment in which the present invention is embodied in a pachinko gaming machine will be described with reference to FIGS.
Follow the instructions below. As shown in FIG. 1, a game board 2 having a game area 1 is incorporated in a pachinko game machine.
In the game area 1, a start opening 3 as a predetermined area, a special symbol display (hereinafter simply referred to as "display") 4, and a special winning opening 5
Are provided respectively. The starting opening 3 is provided with a passage (not shown) for a game ball 6 as a game medium, and a blade 3a for narrowing or widening the entrance of the passage. Indicator 4
Is located above the starting port 3 and displays various types of images. As part of this image, multiple symbol rows, for example,
There are a left symbol column 7, a middle symbol column 8 and a right symbol column 9.

On the display 4, the symbols 1 in each of the symbol columns 7 to 9
The variation of 0 is started all at once based on the winning of the game balls 6 to the starting opening 3. The fluctuation is in a predetermined order, for example, the left symbol column 7,
The right symbol row 9 and the middle symbol row 8 are stopped in this order. All symbols row 7
When the variation of ~ 9 is stopped, the combination of the symbols displayed (variation stop symbol, hereinafter referred to as "stop symbol") is a predetermined combination of big hits, that is, the same type of stop symbols is along the big hit line. There may be a combination of the same stop symbols when arranged side by side (for example, 777). When the combination of the big hits is established, the special electric auditors work and the big hit game state that is advantageous to the player is reached, that is, more prize balls can be won. It should be noted that, as described above, determining whether or not “a big hit game state occurs” with the variation stop mode of the symbol 10 on the display 4 as an essential requirement is also referred to as “lottery”.

Further, the pachinko gaming machine is in the reach gaming state prior to the jackpot gaming state. The reach game state is a state immediately before the big hit game state. For example, the variation of the right symbol column 9 stops on the big hit line with the symbol 10 of the same kind as the symbol in the left symbol column 7, and then the variation of the middle symbol column 8 causes the left and right symbol columns 7, A typical state is a combination of big hits if stopped by a symbol 10 of the same kind as the stopped symbol at 9.

The special winning opening 5 is located below the starting opening 3, and comprises a winning area 12, a shutter 13 and a special winning solenoid (hereinafter simply referred to as "solenoid") 14. A V zone 15 opens at the center of the winning area 12,
Passages 16 are open on both left and right sides. Solenoid 14
Is drivingly connected to the shutter 13, and the excitation causes the shutter 13 to be tilted down to open the winning area 12, and the demagnetization causes the shutter 13 to stand up to close the winning area 12.

In addition to the above, as shown in FIG. 3, the pachinko gaming machine incorporates a speaker 17 for producing a sound effect and changing the type of the sound effect in accordance with the progress of the game. In addition, the pachinko gaming machine incorporates a lamp 18 that changes the mode of light irradiation according to the progress of the game.

As shown in FIG. 1, as a sensor for detecting a game situation which changes according to the operation of the player, the game board 2 has a switch 21 for a starting port, a switch 22 for a V zone and a signal transmitting means, and a switch 22 for a V zone. Count switches 23 are attached respectively. Of these, V zone switch 22
Detects the passage of the game ball 6 in the V zone, and the count switch 23 detects the winning of the game ball 6 in the winning area 12 (passage of the V zone and passage).

The starting port switch 21 is a sensor for detecting the winning of the game ball 6 into the starting port 3, and as shown in FIG. 2, a detection unit 24 which outputs a signal in accordance with the passage of the game ball 6. , And a pair of signal lines (a first signal line 26 and a second signal line 27) that are connected to the detection unit 24 via a drive circuit 25 and are twisted together. By thus being twisted together, both signal lines 26, 27 form a so-called twisted pair line. As the detection unit 24, a type that is not easily affected by electromagnetic noise, for example,
As a micro switch, there is a type that detects the passage of the game ball 6 by a mechanical contact that accompanies the contact with the game ball 6. Further, like the photo sensor, when the game ball 6 passes between the light emitting element and the light receiving element, the change in the amount of light entering the light receiving element is detected, or the light is emitted from the light emitting element and reflected by the game ball 6. There is also a type in which a light receiving element detects a change in the state of the generated light.

The drive circuit 25 generates a two-phase signal (first signal, second signal) based on the signal generated by the detector 24, and transmits the two-phase signal using the two sets of signal lines 26 and 27. (See Figure 4). The first signal is a signal transmitted through the first signal line 26, and its voltage V1 has two values VL and VH.
(> VL). The voltage VL is a value when the game ball 6 does not pass through the detection unit 24, and VH is a value when it passes. The second signal is the second signal line 27.
Is a signal transmitted through. The second signal is the game ball 6
The respective voltages when passing and when not passing are signals which are in an inverse relationship to the respective voltages of the first signal (inverted signal of the first signal). The voltage V2 of the second signal has a high value VH when the game ball 6 does not pass through the detection unit 24, and has a low value VL when it passes. Here, at each signal, the game ball 6
Is the difference (absolute value) between the voltage when the light passes through the detection unit 24 and the voltage when the light does not pass through.

As shown in FIG. 3, the pachinko gaming machine is provided with a main controller 28 as a detection judging means, a lottery means and a special game state generating means. The main controller 28 constitutes a game medium detecting means together with the starting opening switch 21. The starter switch 21, the V-zone switch 22, and the count switch 23 described above are connected to the main controller 28. The solenoid 14 is connected to the main controller 28, the speaker 17 is connected to the main controller 28 via the audio board 29, and the lamp board 3 is connected.
The lamp 18 is connected via 1. Further, the display device 4 is connected to the main control device 28 via the sub control device 32.

Next, the operation and effect of the pachinko gaming machine configured as described above will be described. The flowchart of FIG. 5 shows one of the routines executed by the main controller 28. This routine is a game ball detection routine for detecting whether or not the game ball 6 has won the start port 3 based on the first signal and the second signal of the switch 21 for the start port, and a power supply to the pachinko gaming machine. With the addition, it is repeated every predetermined time.

Main controller 28 first reads voltages V1 and V2 of both signals in step S10, and calculates a difference ΔV (= V1-V2) between them in step S20. here,
In the first signal, the voltage VH when the game ball 6 passes the detection unit 24 and the voltage VL when the game ball 6 does not pass are different from each other. Further, in the second signal which is the inversion signal of the first signal, the voltage when the game ball 6 passes the detection unit 24 is the same value (VL) as the voltage of the first signal when the game ball 6 does not pass.
The voltage when the game ball 6 does not pass becomes the same value as the voltage (VH) of the first signal when the game ball 6 passes. Therefore, the difference ΔV when the game ball 6 passes is α, and the difference ΔV when the game ball 6 does not pass is −α.

On the other hand, when the electromagnetic noise of the voltage VN is similarly superimposed on the first signal and the second signal, the voltages V1 and V2 of each signal are increased by the amount of the superimposed electromagnetic noise voltage VN (or Becomes low), and the waveforms of both signals are different from the waveforms when electromagnetic noise is not superimposed. However, the difference ΔV when the game ball 6 passes the detection unit 24 is α
And the difference ΔV when not passing is −α. This relationship holds as long as the electromagnetic noise voltage VN superimposed on the first signal and the electromagnetic noise voltage VN superimposed on the second signal are the same. In this way, even if electromagnetic noise is superposed, the voltage difference ΔV between the two signals is not affected by the superposition.

Next, in step S30, the difference Δ
It is determined whether V is the same as α. If this determination condition is satisfied (ΔV = α), the game ball passing flag F is set to “1” indicating that the game ball 6 is passing in step S40. The initial value of the game ball passage flag F (the value when the pachinko gaming machine is powered on) is "0". On the other hand, if the determination condition of step S30 is not satisfied (ΔV ≠ α), the game ball passage flag F is set to “0” indicating that the game ball 6 has not passed in step S50. And step S
After performing the processing of 40 and S50, the game ball detection routine is ended. Note that, as the process of step S30, instead of the process described above, for example, it may be determined whether or not the difference ΔV is a positive value. In this case, if the difference ΔV is a positive value,
It is assumed that the game ball 6 has passed, and if it is a negative value, the game ball 6 is not passed.

In the present embodiment, the processing of steps S30, S40 and S50 in the game ball detection routine described above corresponds to the detection determination means.

FIG. 4 shows an example of the correspondence relationship among the first signal, the second signal, the difference ΔV, and the game ball passage flag F. t1
In the period before t2, the period from t2 to t3, the period from t4 to t5, and the period after t6, the electromagnetic noise is not superimposed and the game ball 6 is not winning in the starting opening 3. .
During this period, since V1 = VL and V2 = VH, the difference ΔV becomes −α. Therefore, in the game ball detection routine, the processing is performed in the order of steps S10 → S20 → S30 → S50, and the game ball 6 has not passed the detection unit 24, that is, the game ball 6 has won the starting opening 3. There is no (F = 0).

During the period from t1 to t2, the electromagnetic noise is not superimposed and the game ball 6 wins the starting opening 3.
In this period, since V1 = VH and V2 = VL, the difference ΔV becomes α. Therefore, in the game ball detection routine, the processing is performed in the order of steps S10 → S20 → S30 → S40, and the game ball 6 has passed through the detection unit 24.
That is, the game ball 6 has won the starting opening 3 (F =
1).

In the period from t3 to t4, when the game ball 6 is not winning in the starting opening 3, the electromagnetic noise of the voltage VN is superimposed on both signals. In this period, V1
= VL + VN, V2 = VH + VN, and the signal waveform is different from that when electromagnetic noise is not superimposed. However, the difference ΔV becomes −α as in the case where the electromagnetic noise is not superimposed. This is because the same voltage VN is applied to both signals, so that the difference between them is zero and the influence of the voltage VN on the difference ΔV is eliminated. Therefore, in the game ball detection routine, steps S10 → S20 → S3
Processing is performed in the order of 0 → S50, and the game ball 6 is detected by the detection unit 24.
Is not passed, that is, the game ball 6 is not winning in the starting opening 3 (F = 0).

In the period from t5 to t6, when the game ball 6 wins the starting opening 3, the electromagnetic noise of the voltage VN is superimposed on both signals. In this period, V1 = VH +
Since VN and V2 = VL + VN, the signal waveform is different from that when electromagnetic noise is not superimposed. However, the difference ΔV
Becomes α as in the case where electromagnetic noise is not superimposed. This is because the same voltage VN is applied to both signals, so that the difference between them is zero and the influence of the voltage VN on the difference ΔV is eliminated. Therefore, in the game ball detection routine, steps S10 → S20 → S30 → S4
The processing is performed in the order of 0, and the gaming ball 6 has passed through the detection unit 24, that is, the gaming ball 6 has won the starting opening 3 (F = 1). In this way, the game ball passing flag F
, Whether or not electromagnetic noise is superimposed,
It becomes the same state (correct value).

By the way, the game on the pachinko gaming machine is proceeded as follows based on the game ball passing flag F mentioned above. When the game ball passing flag F is "1", the main controller 28 performs a lottery functioning as a lottery means to determine a display control command (display command) regarding a combination of a symbol variation time and a variation stop symbol, This is transmitted to the sub control device 32. The variable stop symbol is composed of a jackpot symbol, an out-reach symbol and an out symbol. What is the symbol variation time?
After all the symbol rows 7 to 9 start changing at the same time, the fluctuation is stopped in the order of the left symbol row 7 and the right symbol row 9, and finally the middle symbol row 8 is the time required to stop the fluctuation. . When the game ball passing flag F is "0", the lottery is not performed.

On the other hand, when the sub-control device 32 receives the display command, it executes various arithmetic processes in accordance with a control program prepared in advance, and displays the display 4 based on the symbol variation time and the variation stop symbol instructed by the display command. Activate. In the display device 4, all the symbol columns 7 to 9 start to fluctuate all at once, and then the fluctuation is stopped in the order of the left symbol column 7 and the right symbol column 9, and after passing through one of a plurality of types of reach effects. The fluctuation of the middle symbol row 8 is stopped. Or, all the symbol rows 7-9
After the fluctuation starts, the fluctuation is stopped continuously in the order of the left symbol column 7, the right symbol column 9, and the middle symbol column 8. That is, the reach effect is removed without being performed. At the time of this stop, each symbol row 7 ~
At 9, the corresponding variable stop symbol is displayed.

After transmitting the display command, the main control unit 28 transmits a definite control command (confirmation command) for definite that the variation has stopped to the sub control unit 32 when the symbol variation time suggested by the command has elapsed. To do. Further, when the combination of the variable stop symbols in all the symbol columns 7 to 9 is a predetermined jackpot combination, the solenoid 14 is excited. Then, the shutter 13 falls down and the special winning opening 5 is opened.
When more than a predetermined number of game balls 6 are won after the opening of the winning area 12, or when the scheduled closing time comes, the solenoid 14 is demagnetized. Then, the shutter 13 stands up and the winning area 12 is closed. The number of times the game ball 6 is detected by the count switch 23 is used as the winning number of the game ball 6. The game ball 6 won during the opening of the winning area 12 passes through the V zone 15, and when this is detected by the V zone switch 22, the winning area 12 is closed and then opened again. In this way, the main controller 28
Functions as a special game state generating means and generates a special game state (big hit game state) in which more prize balls can be obtained. Then, after the cycle of opening and closing the prize area 12 is repeated a predetermined number of times, the big hit game state is ended.

In addition, the main controller 28 sends commands corresponding to the display command and the confirmation command to the voice board 29 and the lamp board 31, respectively. In response to this command, the voice board 29 synchronizes with the timing of start and stop of fluctuation of the symbol 10 on the display 4, and the speaker 17
Outputs a command signal for generating a sound effect. Similarly, the lamp board 31 outputs a command signal for causing the lamp 18 to generate a plurality of types of light.

As described above, in the pachinko gaming machine of the present embodiment, the electromagnetic waves generated from the surrounding electronic devices and the electromagnetic waves intentionally generated by the radio wave goto using a device such as a transceiver are signal lines 26 and 27. When superimposed as noise (electromagnetic noise) on the signal transmitted by, each signal has a waveform different from the waveform when electromagnetic noise is not superimposed. However, the difference ΔV between the voltages of the two signals V1 and V2
When the game ball 6 does not pass through the detection unit 24, it becomes −α regardless of whether or not electromagnetic noise is superimposed, and when it passes, it becomes α regardless of whether or not electromagnetic noise is superimposed.
Even if electromagnetic noise is superposed, the difference ΔV is not affected by the superposition.

Whether or not the game ball has won the starting opening 3 is a difference Δ.
Although it is determined based on V, as described above, unless the difference ΔV is affected by the superposition of electromagnetic noise, this determination result is obtained when the electromagnetic noise is superposed and when it is not superposed. Will be the same. Therefore, unlike the prior art, in this embodiment, even if electromagnetic noise is superimposed,
It is possible to eliminate the influence of that and solve the problem that each part of the pachinko gaming machine malfunctions and the game progresses. Therefore, even if the electromagnetic wave is synchronized with the cycle in which the big hit game state occurs, the big hit game state occurs even when the game ball 6 is not winning in the starting opening 3 due to an illegal act. Can be prevented.

Further, when the electromagnetic wave is generated from the electromagnetic wave generation source, if the first signal line and the second signal line are separated from each other, the electromagnetic wave may be superimposed as a signal on one signal line as electromagnetic noise. is there. However, both signal lines 2
In the present embodiment in which 6 and 27 are close to each other, electromagnetic noise of the same voltage VN is likely to be superposed on the signals of both signal lines 26 and 27, and the difference ΔV between the voltages V1 and V2 of both signals is influenced by the superposition. It is hard to receive. The determination result of the presence or absence of the starting mouth winning is surely the same when the electromagnetic noise is superimposed and when it is not. Particularly, in the present embodiment in which the first signal line 26 and the second signal line 27 are twisted with each other to form a twisted pair line, they are closely attached and integrated. Therefore, when an electromagnetic wave is generated from the electromagnetic wave generation source in the vicinity of the twisted pair wire, the signal on both signal lines 26 and 27 is further added to the signals on both signal lines 26 and 27 as electromagnetic noise of the same voltage VN, as compared with the case where both signal lines are simply approaching. It becomes easy to overlap. Therefore, the above-described action and effect (prevention of malfunction) can be more reliably exhibited.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 6 is a flow chart corresponding to FIG. 5, and FIG. 7 is a timing chart corresponding to FIG. In the present embodiment, the first signal line 26 and the second signal line 26 of the starting port switch 21 are
When the signal lines 27 are separated from each other and an electromagnetic wave is generated from the electromagnetic wave generation source, one of the signal lines 26 (or 27)
It is easy to superimpose as electromagnetic noise only on the signal. Also, the contents of the processing of the game ball detection routine are slightly changed. Other configurations, such as the mechanical configuration (see FIG. 1) and the electrical configuration (see FIG. 3) of the pachinko gaming machine, are the same as those in the first embodiment. Therefore, the description of the mechanical configuration and the electrical configuration is omitted. Further, in the game ball detection routine, the same processes as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the game ball detection routine of FIG. 6, the main controller 28 sequentially performs the processing of steps S10 and S20. Subsequently, in step S30a, it is determined whether or not the absolute value | ΔV | of the difference ΔV is the same as the predetermined value α. The value α is the same as the value α described in the first embodiment.

Here, the voltage V1 of the first signal and the voltage V2 of the second signal which is the inverted signal thereof are the same as those described in the first embodiment. Therefore, the difference ΔV between the voltages V1 and V2 when the game ball 6 passes is the value α, and the difference ΔV when the game ball 6 does not pass is −α. And
The absolute value of the difference ΔV is the same value α regardless of whether or not the game ball 6 has passed.

On the other hand, the electromagnetic noise of the voltage VN is the first
If it is superimposed only on the signal, the voltage V1 of the first signal becomes higher (or lower) by the voltage VN of the superimposed electromagnetic noise, and the signal waveform is different from the waveform when the electromagnetic noise is not heavy. The difference ΔV and its absolute value are different from the difference ΔV and its absolute value when electromagnetic noise is not superimposed. This can be said whether the game ball 6 is passing or not. Similarly, when electromagnetic noise is superimposed only on the second signal, the difference ΔV and its absolute value are different from the difference ΔV and its absolute value when electromagnetic noise is not superimposed. This relationship holds as long as electromagnetic noise is superimposed on only one signal.

Next, when the determination condition of the step S30a is satisfied (| ΔV | = α), it is determined that both signals are valid signals, and the game ball 6 is passed in steps S35, S40 and S50. Determine the presence or absence of. Specifically, in step S35, it is determined whether the voltage V1 of the first signal is VH. If this determination condition is satisfied (V1 = VH), the game ball passage flag F is set to "1" in step S40 and it is not satisfied (V1 ≠).
VH) and the flag F is set to "0" in step S50.
Set to.

On the other hand, if the determination condition of step S30a is not satisfied (| ΔV | ≠ α), it is determined that the signal is invalid, and the game ball passage flag F is set to "0" in step S50. Then, steps S40 and S5
After performing the process of 0, the game ball detection routine is ended.
As the processing of step S35, instead of the above-described one, it may be determined whether or not the voltage V2 of the second signal is VL. Alternatively, the difference ΔV in step S20 may be used. In this case, if the difference ΔV is a positive value, it is assumed that the game ball 6 has passed, and if the difference ΔV is a negative value, the game ball 6 is not passed.

In this embodiment, steps S30a, S35, S40 and S5 in the game ball detection routine described above.
The processing of 0 corresponds to the validity determining means and the passage determining means,
The processing of steps S30a and S50 corresponds to non-passage determining means.

FIG. 7 shows an example of the correspondence relationship among the first signal, the second signal, the difference ΔV, the absolute value of the difference | ΔV |, and the game ball passing flag F. A period before t11, t12 to t1
The period of 3, the period of t14 to t15, the period of t16 to t17, the period of t18 to t19, and the period after t20,
It shows a case where the electromagnetic noise is not superimposed and the game ball 6 has not won the start opening 3. In this period, V1 = VL,
Since V2 = VH, the voltage difference ΔV between both signals is −
becomes α, and its absolute value becomes α. Therefore, in the game ball detection routine, steps S10 → S20 → S30a →
The processing is performed in the order of S35 → S50, and the game ball 6 has not passed through the detection unit 24, that is, the game ball 6 is the starting opening 3
No winning (F = 0).

During the period from t11 to t12, the electromagnetic noise is not superimposed and the game ball 6 wins the starting opening 3. In this period, since V1 = VH and V2 = VL, the difference ΔV and its absolute value are α. Therefore, in the game ball detection routine, steps S10 → S20 → S3
Processing is performed in the order of 0a->S35-> S40, and the game ball 6 has passed through the detection unit 24, that is, the game ball 6 has won the starting opening 3 (F = 1).

The period from t13 to t14 shows the case where the electromagnetic noise of the voltage VN is superimposed on the first signal when the game ball 6 is not winning in the starting opening 3. In this period,
Since V1 = VL + VN and V2 = VH, the first signal has a signal waveform different from that when electromagnetic noise is not superimposed. Since the voltage VN is applied to only one signal, the difference Δ
V becomes larger than the value -α when electromagnetic noise is not superimposed. Along with this, the absolute value of the difference ΔV also becomes smaller than the value α when electromagnetic noise is not superimposed.
Therefore, in the game ball detection routine, step S10 →
The processing is performed in the order of S20 → S30a → S50, and the game ball 6 has not passed the detection unit 24, that is, the game ball 6
Is not awarded to the starting opening 3 (F = 0).

The period from t15 to t16 shows the case where the electromagnetic noise of the voltage VN is superimposed on the second signal when the game ball 6 is not winning in the starting opening 3. In this period,
V1 = VL and V2 = VH + VN, and the second signal has a signal waveform different from that when electromagnetic noise is not superimposed. Since the voltage VN is applied only to the second signal, the difference ΔV
Is smaller than the value −α when electromagnetic noise is not superimposed. Along with this, the absolute value of the difference ΔV also becomes larger than the value α when electromagnetic noise is not superimposed. Therefore, in the gaming ball detection routine, the above t13 to t14
Processing similar to that in the period is performed.

The period from t17 to t18 (t19 to t20) shows the case where the electromagnetic noise of the voltage VN is superimposed on the second signal (first signal) when the game ball 6 wins the starting opening 3. . In this period, V1 = VH, V2 = VL +
VN (V1 = VH + VN, V2 = VL), and the second signal (first signal) has a signal waveform different from that when electromagnetic noise is not superimposed. Since the voltage VN is applied only to the second signal (first signal), the difference ΔV becomes smaller (larger) than the value α when electromagnetic noise is not superimposed.
Along with this, the absolute value of the difference ΔV also becomes smaller (larger) than the value α when electromagnetic noise is not superimposed. Therefore, in the gaming ball detection routine, the above t13 to t14
Processing similar to that in the period is performed. In this paragraph, the numbers in parentheses correspond to the period from t19 to t20.
Further, although not described, the point that the game in the pachinko gaming machine is advanced based on the game ball passage flag F set in the game ball detection routine is the same as in the first embodiment.

As described above, in the pachinko gaming machine of the present embodiment, the signal on which electromagnetic noise is superimposed and the signal on which electromagnetic noise is not superimposed are distinguished based on whether or not the absolute value of the difference ΔV matches the predetermined value α. Different. Then, the signal without electromagnetic noise is used as a valid signal for the progress of the game,
The signal on which the electromagnetic noise is superimposed is not used as an invalid signal for the progress of the game.

Therefore, the second embodiment employs a method slightly different from that of the first embodiment, but eliminates the influence of the superposition of electromagnetic noise, and each part of the pachinko gaming machine malfunctions to play a game. It is possible to solve the problem that progresses. It is possible to prevent the big hit game state from occurring even if electromagnetic waves are generated in synchronization with the cycle in which the big hit game state occurs due to an illegal act of the radio wave goto. However, when electromagnetic noise is superimposed on both signals when the game ball 6 wins the start opening 3, the game proceeds as winning with the first embodiment, whereas it is treated as an invalid signal in the second embodiment. The game is advanced with no prize. Therefore, in this case, in the second embodiment, the lottery is not performed, and the big hit game state does not occur.

The present invention can be embodied in another embodiment shown below. (1) The present invention may be embodied in a pachinko gaming machine of a type different from the above embodiment. For example, a third-class (proprietary) pachinko gaming machine, a pachinko gaming machine in which a jackpot gaming state is generated after a lottery has been performed a plurality of times, and the probability of a jackpot becomes a high probability due to the establishment of a predetermined condition. An example is a stochastic pachinko game machine.
Further, the present invention may be embodied in a game machine other than a pachinko game machine, for example, an arepachi, an arrangement ball, or the like.

(2) The present invention can also be applied to a game machine using a sensor other than the starting port switch 21, for example, a V zone switch 22 and a count switch 23 as signal transmission means.

(3) In the first embodiment, in order to prevent electromagnetic noise from being superposed on one of the first signal line 26 and the second signal line 27, as described above, they are twisted with each other to form a twisted pair wire. Is effective, but both signal lines 2
It is also possible to arrange 6 and 27 in a state of approaching (for example, contacting) each other without twisting them.

(4) As the signal transmission means, a type different from the above-mentioned embodiments, for example, a differential type dedicated receiver or a photo coupler may be used.

(5) Electromagnetic noise may be superimposed not only on the signal lines of the various sensors described above but also on the connectors between the boards and the signal lines. The method of the present invention can also be adopted as a countermeasure against this electromagnetic noise.
