Abstract

PROBLEM TO BE SOLVED: To eliminate the effect of electromagnetic noise and prevent the malfunction even if the electromagnetic noise superimposes on signals of a sensor for detecting the passage of game media. SOLUTION: In a Pachinko game machine, the passage of game balls to a starting hole is detected by a game medium detecting means, and a game proceeds according to the result in the detection. The game medium detecting means has a starting hole switch and a main controller. The starting hole switch transmits a first signal whose voltages V1 vary depending on whether game balls pass through the starting hole or not through a first signal line, and transmits a second signal whose voltages V2 when game balls pass through the starting hole and when game balls don't pass through the starting hole are in the reverse relation between each other to the relation between the voltages of the first signal, through a second signal line. The main controller judges the entrance of a game ball into the starting hole based on the difference ΔV between the voltages V1 and V2 by utilizing the fact that the difference ΔV when the electromagnetic noise of the same voltage VN overlaps with the first and second signals is the same as a case when the electromagnetic noise doesn't overlap with the signals.

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 particularly, to a sensor for detecting whether a game medium such as a game ball has passed a predetermined area, and playing the game in accordance with the detection result. In a game machine.

[0002]

2. Description of the Related Art Conventionally, a plurality of symbol rows (for example, left, middle, and right symbol rows) are variably displayed and stopped on a display incorporated in a game board by using, for example, a main controller and a sub controller. There is known a pachinko gaming machine that generates a jackpot game state that is advantageous to a player based on the fluctuation stop mode or the like. In this pachinko gaming machine, the winning of the game ball at the starting port is detected by a sensor (starting port switch). The starting port switch transmits a signal having a different voltage between when the game ball does not pass and when the game ball passes, for example, a signal having a higher voltage than when the game ball does not pass through a single signal line. When the voltage of the transmitted signal is higher than a predetermined value, the main controller determines that the game ball has won the starting port and performs a lottery,
A display command relating 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 activates the display according to the symbol change time and the change stop symbol specified by the display command. After starting the change of all the symbol rows simultaneously, the change of the symbol rows is continuously stopped in the order of, for example, 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 after the reach effect, the fluctuation of the middle symbol row is stopped. If the combination of the fluctuation stop symbols in all the symbol rows is a predetermined combination of big hits, a big hit game state in which more winning balls can be obtained, such as opening a big winning opening, is generated. . In the pachinko gaming machine, various sensors are used in addition to the start-up switch, and the progress of the game is changed depending on the detection result of the game ball by the sensor.

[0004]

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

Therefore, an object of the present invention is to eliminate the influence of electromagnetic noise even when the signal of a sensor for detecting the passage of a game medium such as a game ball is superimposed on the signal, thereby preventing malfunction. It is to provide a gaming machine.

[0006]

Means for solving the above problems will be described below. The operation and the like will be described as necessary.

Means 1. In a gaming machine which detects a passing state of a game medium in a predetermined area by a game medium detecting means and proceeds with a game in accordance with a result of the detection, the game medium detecting means determines whether or not the game medium has passed. A first signal having a different voltage is transmitted through a first signal line, and a second signal having a voltage opposite to that of the first signal when each of the first and second signals passes and is not passed through the game medium. The second
A signal transmission unit that transmits by a signal line, and a detection determination unit that determines whether the game medium has passed through the predetermined area based on a difference between both voltages of the first signal and the second signal by the signal transmission unit. A gaming machine comprising:

According to the means 1, the passing state of the game medium in the predetermined area is detected by the game medium detection means.
Upon this detection, in the signal transmission means, the first signal is transmitted through the first signal line, and the second signal is transmitted 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 is 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 is 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 it does not pass is defined as α. Then, if the difference between the voltages of the two signals when the game medium passes is α, the difference between the voltages when the game medium does not pass is −α.

On the other hand, when the electromagnetic noise is superimposed on the first signal and the second signal in the same manner, the voltage of each signal is increased (or decreased) by the voltage of the electromagnetic noise, and the waveforms of both signals are changed. However, the waveform differs from the waveform when no electromagnetic noise is superimposed. However, the difference between the voltages of the two signals when the game medium passes is α, and the difference between the voltages of the two 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 the electromagnetic noise is superimposed, 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 through a 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 the two signals is not affected by the superposition of the electromagnetic noise, the determination result of the detection determination unit is the same whether or not the electromagnetic noise is superimposed. Therefore, in the gaming machine, each part operates according to the detection result of the game medium detecting means and the game proceeds, but even if the electromagnetic noise is superimposed, each part operates in the same manner as when the electromagnetic noise is not superimposed. I do. There is no worry about malfunction due to electromagnetic noise.

Means 2. The gaming machine according to claim 1, wherein the first signal line and the second signal line are arranged close to each other.

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

Means 3. The gaming machine according to claim 2, wherein the first signal line and the second signal line are twisted with each other to form a twisted pair line.

According to the means 3, the first signal line and the second signal line
When the signal wires are twisted with each other to form a twisted pair wire, they are in close contact and integrated. For this reason, when an electromagnetic wave is generated from an electromagnetic wave source near the twisted pair line, it becomes easier to superimpose on the signals of both signal lines as electromagnetic noise of the same voltage as compared to a case where both signal lines are simply approaching. .

Means 4. In a gaming machine which detects a passing state of a game medium in a predetermined area by a game medium detecting means and proceeds with a game in accordance with a result of the detection, the game medium detecting means determines whether or not the game medium has passed. A first signal having a different voltage is transmitted through a first signal line, and a second signal having a voltage opposite to that of the first signal when each of the first and second signals passes and is not passed through the game medium. The second
A signal transmission means for transmitting by a signal line, and regarding 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 a predetermined value, A game machine comprising: validity determining means for determining that both signals are invalid when the absolute value is different from the predetermined value.

According to the means 4, the passing state of the game medium in the predetermined area is detected by the game medium detection means.
Upon this detection, in the signal transmission means, the first signal is transmitted through the first signal line, and the second signal is transmitted 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 is 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 is 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 it does not pass is defined as α. Then, if the difference between the voltages of the two signals when the game medium passes is α, the difference between the voltages when the game medium does not pass is −α. The absolute value of this voltage difference is the same value α irrespective of the presence or absence of the passage of the game medium.

On the other hand, when the electromagnetic noise is superimposed only on the first signal, the absolute value of the voltage difference is different from the absolute value when the electromagnetic noise is not superimposed. This is true whether the game medium passes through the signal transmission means or not. Similarly, when the electromagnetic noise is superimposed only on the second signal, the absolute value of the difference between the voltages is different from the absolute value when the electromagnetic noise is not superimposed, regardless of the presence or absence of the passage of the game medium. This relationship holds as long as the electromagnetic noise is superimposed on only one signal.

On the other hand, the validity determining means compares the absolute value of the difference between the voltages of the two signals with a predetermined value. This predetermined value is
In each signal, a difference (absolute value) between a voltage when the game medium passes and a voltage when the game medium does not pass. And
If the absolute values match the predetermined value, it is determined that both signals are valid, and if they do not match, it is determined that the signals are invalid. Thus, based on the relationship between the absolute value of the difference between the two voltages and the predetermined value, the signal on which the electromagnetic noise is superimposed,
Signals that are not superimposed are distinguished. Then, the signal determined to be valid (the signal on which the electromagnetic noise is not superimposed) is used for the progress of the game, and the signal determined to be invalid (the signal on which the electromagnetic noise is superimposed) must be used for the progress of the game. Therefore, even if the electromagnetic noise is superimposed, there is no fear of malfunction due to the electromagnetic noise.

Means 5 The means 4 further comprises a 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 accordance with the validity determination by the validity determining means. A gaming machine.

According to the means 5, if the absolute value of the difference between the two voltages is the predetermined value, it is assumed that the first signal and the second signal from the game medium detecting means are signals on which no electromagnetic noise is superimposed. The validity is determined by the validity determining 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 proceeds according to the determined content, that is, the passing situation of the game medium in the predetermined area.

Means 6 The gaming machine according to claim 4, further comprising a non-passage determination unit configured to determine whether or not the game medium passes through the predetermined area according to the invalidity determination by the validity determination unit.

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 through the predetermined area. Then, the game proceeds according to the determined content. Therefore, if the electromagnetic noise is superimposed on only one of the signals, a situation advantageous to the player does not occur even if the game medium passes through the predetermined area at that time.

Means 7 In any one of the means 1 to 3, a lottery means for performing a lottery on condition that the game medium detection means detects the passage of the game medium through the predetermined area, and a lottery by the lottery means being a hit, A gaming machine further comprising: a special game state generating 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 through the predetermined area, the lottery means performs the lottery. If the lottery result is a hit, the special game state generating means generates a special game state advantageous to the player. Here, as described above, since the detection result of the game medium detection unit is the same between the case where the electromagnetic noise is superimposed and the case where the electromagnetic noise is not superimposed, even though the game medium has not passed through the predetermined area, The lottery is not performed due to the superposition of the electromagnetic noise, and the special game state associated therewith does not occur.

[0025]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) Hereinafter, a first embodiment of the present invention embodied in a pachinko game machine will be described with reference to FIGS.
It will be described according to. As shown in FIG. 1, a gaming board 2 having a gaming area 1 is incorporated in a pachinko gaming machine.
In the gaming area 1, a starting port 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 port 3 includes a passage (not shown) of the game ball 6 as a game medium, and a blade 3a that narrows or widens the entrance of the passage. Display 4
Is located above the starting port 3 and displays various types of images. As part of this image, a plurality of symbol rows, for example,
There are a left symbol row 7, a middle symbol row 8, and a right symbol row 9.

On the display 4, the symbols 1 in each of the symbol rows 7 to 9 are displayed.
The fluctuation of 0 is started all at once based on the winning of the game ball 6 to the starting port 3. The fluctuation is determined in a predetermined order, for example, the left symbol row 7,
The right symbol row 9 and the middle symbol row 8 are stopped in this order. All pattern rows 7
When the fluctuations of Nos. To 9 are stopped, the combination of the displayed symbols (variable stop symbols, hereinafter referred to as "stop symbols") is a predetermined combination of jackpots, that is, the same type of stop symbol is set along the jackpot line. There are cases where the combination of the same stop symbols when they are arranged side by side (for example, 777). When the big hit combination is established, the special electric accessory is activated, and a big hit gaming state advantageous to the player can be reached, that is, more prize balls can be obtained. In addition, as described above, determining whether or not “the occurrence of the big hit game state” 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 enters the reach gaming state prior to the jackpot gaming state. The reach game state refers to a state immediately before the big hit game state. For example, the variation of the right symbol row 9 stops on the big hit line with the same type of symbol 10 as the stop symbol in the left symbol row 7, and thereafter, the variation of the middle symbol row 8 changes to the left and right symbol rows 7, A typical example is a state in which a big hit combination is achieved by stopping with a symbol 10 of the same type as the symbol stopped at 9.

The special winning opening 5 is located below the starting opening 3, and includes a winning area 12, a shutter 13, and a special winning opening solenoid (hereinafter simply referred to as “solenoid”) 14. A V zone 15 opens at the center of the winning area 12,
Passages 16 are opened on both left and right sides. Solenoid 14
Is driven and connected to the shutter 13 to excite the shutter 13 to excite the shutter area 13 to open the winning area 12, and to demagnetize to raise the shutter 13 to close the winning area 12.

In addition, as shown in FIG. 3, the pachinko gaming machine has a built-in speaker 17 for emitting a sound effect or changing the type of the sound effect in accordance with the progress of the game. Further, the pachinko gaming machine incorporates a lamp 18 that changes the mode of light irradiation in accordance with the progress of the game.

As shown in FIG. 1, as a sensor for detecting a game situation that changes according to the operation of the player, the game board 2 includes a start port switch 21 as a signal transmission means, a V zone switch 22, Each of the count switches 23 is attached. V-zone switch 22
Detects that the game ball 6 has passed through the V zone, and the count switch 23 detects that the game ball 6 has won the prize area 12 (pass of the V zone and passage).

The starting port switch 21 is a sensor for detecting a winning of the game ball 6 to the starting port 3, and as shown in FIG. 2, a detecting section 24 for outputting a signal as the game ball 6 passes. And two sets of signal lines (a first signal line 26 and a second signal line 27) connected to the detection unit 24 via a drive circuit 25 and twisted with each other. By being twisted in this way, both signal lines 26 and 27 constitute a so-called twisted pair line. As the detection unit 24, a type that is not easily affected by electromagnetic noise, for example,
Like a microswitch, there is a type in which the passage of the game ball 6 is detected by a mechanical contact accompanying the contact with the game ball 6. Further, when the game ball 6 passes between the light emitting element and the light receiving element like a photo sensor, a 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 change in the state of the emitted light is detected by a light receiving element.

The drive circuit 25 generates a two-phase signal (first signal and second signal) based on the signal generated by the detection unit 24, and transmits the signal using the two sets of signal lines 26 and 27. (See FIG. 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 a second signal line 27
Is a signal transmitted through The second signal is a game ball 6
Is a signal (inverted signal of the first signal) having a reverse relationship with each voltage of the first signal when passing and not passing through. 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 the game ball 6 has passed. Here, in each signal, the game ball 6
Is the difference (absolute value) between the voltage when the signal passes through the detection unit 24 and the voltage when the signal does not pass.

As shown in FIG. 3, the pachinko gaming machine is provided with a main control device 28 as detection judging means, lottery means and special game state generating means. The main control device 28 constitutes a game medium detecting means together with the starting port switch 21. The above-described starting port switch 21, V zone switch 22, and count switch 23 are connected to the main controller 28. The main controller 28 is connected to the solenoid 14 and the speaker 17 via the audio board 29.
The lamp 18 is connected via 1. The display 4 is connected to the main controller 28 via a sub controller 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 main controller 28. This routine is a game ball detection routine for detecting whether the game ball 6 has won the start port 3 based on the first signal and the second signal of the start port switch 21, and a power supply to the pachinko game machine. It is repeatedly performed at predetermined time intervals with the input.

Main controller 28 first reads voltages V1 and V2 of both signals in step S10, and calculates a difference ΔV (= V1−V2) in step S20. here,
In the first signal, the voltage VH when the game ball 6 passes through the detection unit 24 and the voltage VL when it does not pass are different from each other. In the second signal which is an inverted signal of the first signal, the voltage when the game ball 6 passes through the detection unit 24 is the same value (VL) as the voltage of the first signal when it does not pass.
And 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. Thus, 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 superimposed on the first signal and the second signal in the same manner, the voltages V1 and V2 of each signal are higher (or higher) by the voltage VN of the superposed electromagnetic noise. Lower), and the waveforms of both signals are different from the waveforms when no electromagnetic noise is superimposed. However, the difference ΔV when the game ball 6 passes through the detection unit 24 is α
And the difference ΔV when not passing through is -α. This relationship holds as long as the voltage VN of the electromagnetic noise superimposed on the first signal and the voltage VN of the electromagnetic noise superimposed on the second signal are the same. Thus, even if the electromagnetic noise is superimposed, 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 or not V is equal to 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. Note that the initial value of the game ball passing flag F (the value when the power to the pachinko gaming machine is turned on) is “0”. On the other hand, if the determination condition in step S30 is not satisfied (ΔV ≠ α), the game ball passing 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 steps S40 and S50, the game ball detection routine ends. Note that, instead of the above-described processing in step S30, for example, it may be determined whether 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 the value is a negative value, the game ball 6 has not passed.

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

FIG. 4 shows an example of the correspondence between the first signal, the second signal, the difference ΔV, and the game ball passage flag F. t1
The period before t2, the period from t2 to t3, the period from t4 to t5, and the period after t6 show a case where the electromagnetic noise is not superimposed and the game ball 6 does not win the starting opening 3. .
In this period, since V1 = VL and V2 = VH, the difference ΔV becomes −α. For this reason, in the game ball detection routine, the processing is performed in the order of steps S10 → S20 → S30 → S50, and the game balls 6 do not pass through the detection unit 24, that is, the game balls 6 have won the starting opening 3. (F = 0).

During the period from t1 to t2, the case where the electromagnetic noise does not overlap and the game ball 6 wins the starting opening 3 is shown.
In this period, since V1 = VH and V2 = VL, the difference ΔV becomes α. For this reason, in the game ball detection routine, processing is performed in the order of steps S10 → S20 → S30 → S40, and the game balls 6 pass 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 does not win the starting port 3, the case where the electromagnetic noise of the voltage VN is superimposed on both signals is shown. In this period, V1
= VL + VN, V2 = VH + VN, and the signal waveform is different from that when no electromagnetic noise is superimposed. However, the difference ΔV becomes −α similarly to the case where the electromagnetic noise is not superimposed. This is because the same voltage VN is applied to both signals, so that their difference is zero, and the effect of the voltage VN on the difference ΔV is eliminated. Therefore, in the game ball detection routine, steps S10 → S20 → S3
The processing is performed in the order of 0 → S50, and the game ball 6 is
, That is, the game ball 6 does not win the starting port 3 (F = 0).

In the period from t5 to t6, when the game ball 6 wins the starting port 3, the case where the electromagnetic noise of the voltage VN is superimposed on both signals is shown. In this period, V1 = VH +
VN, V2 = VL + VN, and the signal waveform is different from that when no electromagnetic noise is superimposed. However, the difference ΔV
Is α as in the case where no electromagnetic noise is superimposed. This is because the same voltage VN is applied to both signals, so that their difference is zero, and the effect 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 it is determined that the game ball 6 has passed the detection unit 24, that is, the game ball 6 has won the starting opening 3 (F = 1). Thus, the game ball passing flag F
Is, whether or not electromagnetic noise is superimposed,
It will be in the same state (correct value).

By the way, the game in the pachinko game machine proceeds as follows based on the above-mentioned game ball passing flag F. When the game ball passing flag F is “1”, the main control device 28 performs a lottery by functioning as a lottery device, determines a display control command (display command) relating to a combination of a symbol variation time and a variation stop symbol, This is transmitted to the sub control device 32. The fluctuation stop symbol includes a big hit symbol, a miss reach symbol, and a miss symbol. The symbol variation time is
This is the time required for all the symbol rows 7 to 9 to start changing simultaneously, and then stop changing in the order of the left symbol row 7 and the right symbol row 9 and finally stop changing the middle symbol row 8. . When the game ball passing flag F is “0”, the lottery is not performed.

On the other hand, upon receiving the display command, the sub-control unit 32 executes various arithmetic processing according to a control program prepared in advance, and displays the display 4 based on the symbol change time and the change stop symbol specified by the display command. Activate. On the display 4, all the symbol rows 7 to 9 start to change at the same time, then stop changing in the order of the left symbol row 7 and the right symbol row 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 start of the fluctuation, the fluctuation is stopped in the order of the left symbol row 7, the right symbol row 9, and the middle symbol row 8. That is, it comes off without performing the reach effect. At the time of this stop, each symbol row 7 ~
At 9, the corresponding variable stop symbol is displayed.

After the transmission of the display command, the main control device 28 transmits a confirmation control command (confirmation command) to the sub-control device 32 when the symbol variation time indicated by the command elapses and determines that the variation has stopped. I do. Further, if the combination of the fluctuation stop symbols in all the symbol rows 7 to 9 is a predetermined jackpot combination, the solenoid 14 is excited. Then, the shutter 13 falls and the special winning opening 5 is opened.
When a larger number of game balls 6 win than a predetermined number or the scheduled closing time comes after the opening of the winning area 12 starts, the solenoid 14 is demagnetized. Then, the shutter 13 stands up, and the winning area 12 is closed. The number of game balls 6 detected by the count switch 23 is used as the winning number of the game balls 6. When the winning game ball 6 passes through the V zone 15 while the winning area 12 is being opened and is detected by the V zone switch 22, the winning area 12 is closed and then opened again. Thus, main controller 28
Functions as special game state generating means, and generates a special game state (big hit game state) in which more prize balls can be obtained. When the cycle of opening and closing the prize area 12 is repeated a predetermined number of times, the big hit game state ends.

In addition, the main controller 28 transmits commands corresponding to the display command and the determination command to the audio board 29 and the lamp board 31, respectively. In response to this command, the audio board 29 synchronizes with the timing of starting or stopping the fluctuation of the symbol 10 on the display 4 and
Outputs a command signal for generating a sound effect. Similarly, the lamp substrate 31 outputs a command signal for causing the lamp 18 to emit light in a plurality of types.

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 device using the transceiver or the like are transmitted to the signal lines 26 and 27. Are superimposed as noise (electromagnetic noise) on the signals transmitted by the respective components, each signal has a waveform different from the waveform when no electromagnetic noise is superimposed. However, the difference ΔV between the voltages of the two signals V1 and V2 is
When the game ball 6 does not pass through the detection unit 24, it becomes -α regardless of the presence or absence of the superposition of the electromagnetic noise, and when it passes, it becomes α regardless of the presence or absence of the superposition of the electromagnetic noise.
Even if the electromagnetic noise is superimposed, the difference ΔV is not affected by the superposition.

Whether or not a game ball has won the starting port 3 is determined by the difference Δ
The determination result is based on V. As described above, as long as the difference ΔV is not affected by the superposition of the electromagnetic noise, the result of this determination depends on whether the electromagnetic noise is superimposed or not. Will be the same. Therefore, unlike the related art, in the present embodiment, even if the electromagnetic noise is superimposed,
It is possible to eliminate the influence of this and eliminate the problem that each part of the pachinko gaming machine malfunctions and progresses the game. Therefore, even if the radio wave Goto generates an electromagnetic wave in synchronization with the cycle in which the big hit game state occurs when the game ball 6 does not win the starting port 3 due to cheating, the big hit game state occurs. Can be prevented.

When an electromagnetic wave is generated from an 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 on only one signal line signal as electromagnetic noise. is there. However, both signal lines 2
In this embodiment, in which the electromagnetic noise of the same voltage VN is superimposed on the signal of both signal lines 26 and 27, the difference ΔV between the voltages V1 and V2 of the two signals is influenced by the superposition. Hard to receive. The result of the determination as to whether or not there is a start opening winning is surely the same when the electromagnetic noise is superimposed and when it is not. In particular, 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 in close contact and integrated. For this reason, when an electromagnetic wave is generated from an electromagnetic wave source near the twisted pair line, 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 a case where both signal lines are just approaching. It becomes easy to superimpose. Therefore, the above-described functions and effects (prevention of malfunction) can be more reliably achieved.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a flowchart 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
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)
Is easily superimposed as electromagnetic noise only on the signal of Further, the content of the processing of the game ball detection routine is slightly changed. Other configurations, for example, the mechanical configuration (see FIG. 1) and the electrical configuration (see FIG. 3) of the pachinko gaming machine are the same as those of the first embodiment. Therefore, description of the mechanical configuration and the electrical configuration is omitted. In the game ball detection routine, the same processes as those in the first embodiment are denoted 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 performs the processing of steps S10 and S20 in order. Subsequently, in step S30a, it is determined whether or not the absolute value | ΔV | of the difference ΔV is equal to a 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 an inverted signal thereof are the same as those described in the first embodiment. Therefore, the difference ΔV between the two 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
When superimposed on only 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 differs 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 no electromagnetic noise is superimposed. This can be said whether the game ball 6 has passed or not. Similarly, when the electromagnetic noise is superimposed only on the second signal, the difference ΔV and its absolute value are different from the difference ΔV and the absolute value when no electromagnetic noise is superimposed. This relationship holds as long as the electromagnetic noise is superimposed on only one signal.

Next, if the determination condition in step S30a is satisfied (| ΔV | = α), it is determined that both signals are valid signals, and the passing of the game ball 6 is performed in steps S35, S40, and S50. Is determined. Specifically, in step S35, it is determined whether or not the voltage V1 of the first signal is VH. If this determination condition is satisfied (V1 = VH), the game ball passing flag F is set to "1" in step S40, and 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 in step S30a is not satisfied (| ΔV | ≠ α), it is determined that the signal is invalid, and the game ball passing 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 ends.
It should be noted that, instead of the above-described processing in step S35, it may be determined whether or not the voltage V2 of the second signal is VL. Further, the difference ΔV in step S20 may be used. In this case, if the difference ΔV is a positive value, it is determined that the game ball 6 has passed, and if the difference ΔV is a negative value, it is determined that the game ball 6 has not passed.

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

FIG. 7 shows an example of the correspondence relationship between the first signal, the second signal, the difference ΔV, the absolute value | ΔV | of the difference, and the game ball passing flag F. The period before t11, t12 to t1
3, a period between t14 and t15, a period between t16 and t17, a period between t18 and t19, and a period after t20.
The case where the electromagnetic noise is not superimposed and the game ball 6 does not win the starting port 3 is shown. In this period, V1 = VL,
Since V2 = VH, the voltage difference ΔV between the two signals is −
α, and its absolute value is α. For this reason, 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 does not pass through the detection unit 24, that is, the game ball 6
Is not won (F = 0).

In the period from t11 to t12, a case is shown in which the electromagnetic noise is not superimposed and the game ball 6 has won 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
The processing is performed in the order of 0a → S35 → S40, and it is determined that the game ball 6 has passed through the detection unit 24, that is, the game ball 6 has won the starting port 3 (F = 1).

The period from t13 to t14 shows a case where the electromagnetic noise of the voltage VN is superimposed on the first signal when the game ball 6 has not won the starting port 3. During this period,
V1 = VL + VN, V2 = VH, and the first signal has a signal waveform different from that when no electromagnetic noise is superimposed. Since the voltage VN is applied to only one of the signals, the difference Δ
V is larger than the value -α when no electromagnetic noise is superimposed. Accordingly, the absolute value of the difference ΔV becomes smaller than the value α when no electromagnetic noise is superimposed.
For this reason, in the game ball detection routine, step S10 →
The processing is performed in the order of S20 → S30a → S50, and the game ball 6 does not pass through the detection unit 24, that is, the game ball 6
Is not awarded in the starting port 3 (F = 0).

The period from t15 to t16 shows a case where the electromagnetic noise of the voltage VN is superimposed on the second signal when the game ball 6 has not won the starting port 3. During this period,
V1 = VL, V2 = VH + VN, and the second signal has a signal waveform different from that when no electromagnetic noise is superimposed. Since the voltage VN is applied only to the second signal, the difference ΔV
Is smaller than the value −α when no electromagnetic noise is superimposed. Accordingly, the absolute value of the difference ΔV also becomes larger than the value α when no electromagnetic noise is superimposed. Therefore, in the game ball detection routine, the above-mentioned t13 to t14
The same processing as in the period is performed.

During the period from t17 to t18 (t19 to t20), 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 port 3 is shown. . In this period, V1 = VH, V2 = VL +
VN (V1 = VH + VN, V2 = VL), and the second signal (first signal) has a different signal waveform from that when no electromagnetic noise is superimposed. Since the voltage VN is applied only to the second signal (first signal), the difference ΔV is smaller (greater) than the value α when no electromagnetic noise is superimposed.
Accordingly, the absolute value of the difference ΔV becomes smaller (greater) than the value α when no electromagnetic noise is superimposed. Therefore, in the game ball detection routine, the above-mentioned t13 to t14
The same processing as in the period is performed. In this paragraph, the values in parentheses correspond to the period from t19 to t20.
Although the description is omitted, the point that the game in the pachinko gaming machine proceeds based on the game ball passing 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 the electromagnetic noise is superimposed and the signal on which the electromagnetic noise is not superimposed are distinguished based on whether the absolute value of the difference ΔV matches the predetermined value α. I'm different. Then, a signal in which the electromagnetic noise is not superimposed is used as a valid signal in the progress of the game,
A signal on which electromagnetic noise is superimposed is not used as an invalid signal in the progress of the game.

For this reason, the second embodiment employs a technique slightly different from that of the first embodiment, but eliminates the influence of the superposition of the electromagnetic noise and causes the parts of the pachinko gaming machine to malfunction to play the game. It is possible to eliminate the problem of progress. Even if the radio wave goto generates electromagnetic waves in synchronization with the cycle in which the big hit game state occurs due to fraud, it is possible to prevent the big hit game state from occurring. However, if the electromagnetic noise is superimposed on both signals when the game ball 6 wins the starting port 3, the game proceeds as if there is a prize in the first embodiment, but is treated as an invalid signal in the second embodiment. The game is advanced without winning. Therefore, in this case, in the second embodiment, no lottery is performed, and no big hit gaming state occurs.

The present invention can be embodied in another embodiment described below. (1) The present invention may be embodied in a pachinko game machine of a type different from the above-described embodiment. For example, a third-type (rights) pachinko gaming machine, a pachinko gaming machine configured to generate a jackpot game state after performing a lottery, a so-called so-called jackpot having a high probability of becoming a big hit when a predetermined condition is satisfied. Pachinko gaming machines of the probability variation type are exemplified.
Further, the present invention may be embodied in gaming machines other than pachinko gaming machines, for example, arepachi, arrangement balls and the like.

(2) The present invention can be applied to a gaming machine using a sensor other than the start-up opening 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 superimposed on one of the first signal line 26 and the second signal line 27, as described above, they are twisted together to form a twisted pair wire. Is effective, but both signal lines 2
6 and 27 may be arranged close to each other (for example, in contact with each other) without twisting.

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

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