Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko gaming machine having a structure for preventing a fraudulent act in which a variable winning a prize provided on a game board is illegally opened to obtain a profit.

[0002]

2. Description of the Related Art A variable winning a prize hole which is controlled to an open state where a game ball can enter and a closed state where the game ball cannot enter, a ball detecting device for detecting a game ball inside the variable prize hole, and a specific game. When the conditions are met, the variable winning opening is opened and closed, and as the ball detection device detects the game ball that has flowed into the variable winning opening, a special game operation that provides a profit to the player in a predetermined prize ball form. Various pachinko game machines provided with a prize ball control means for controlling and executing are proposed.

In such a pachinko gaming machine, in addition to the variable winning openings, various winning openings are arranged on the gaming board, and the gaming balls that are fired in the gaming area formed by the gaming board are the winning openings. A predetermined prize ball is paid out by flowing into each of the above. Then, as such a variable winning a prize, a large winning a prize which is controlled to be opened when a gaming state of "hit" is established is paid out to the inflowing game ball as compared with the other winning a prizes. The percentage of prize balls is high, which provides many benefits to the player. For example, in a first-class pachinko gaming machine, a game ball passes through the symbol starting area, a plurality of symbols fluctuates, and the combination of symbols that has been fixedly stopped becomes a predetermined winning symbol mode, and a big prize is awarded. It is controlled so that a special game operation in which the mouth is opened is executed. Here, the probability of occurrence of a hit, which is a condition for opening the special winning opening, is set to be relatively low.

[0004]

In the above-mentioned pachinko gaming machine, the profit that can be obtained by the inflow of the game balls to the winning holes other than the special winning opening is higher than that when the game balls are flowing into the special winning opening. Since it is extremely small, the player most desires the special game operation in which the special winning opening is opened. However, since there is a low probability that a specific game state, which is a condition for opening the special winning opening (a hit occurs), is low, some players have a large probability regardless of whether a specific game state is established (a hit occurs). There is an illegal player called a so-called Goto master who tries to make a profit by opening the prize hole illegally. Such an unauthorized player, for example, inserts a wire or the like through a gap on the front surface of the gaming machine and operates it to forcefully open the special winning opening. Then, a fraudulent act of firing a game ball to obtain a large number of prize balls is performed. In addition, there are cases where fraudulent acts such as opening the special winning opening and inserting a game ball directly by removing the transparent plate arranged on the front of the game board will cause a large loss to the game hall where the pachinko game machine is installed. Sometimes suffered.

An object of the present invention is to provide a pachinko gaming machine capable of appropriately preventing an illegal act in which a variable winning a prize opening is illegally opened and a profit is provided as described above.

[0006]

The present invention resides in a pachinko gaming machine provided with a prize ball control means as described above, wherein the prize ball control means performs a special game operation when a specific game condition is satisfied. The operation time from the execution of the control to be started to the execution of the control to be ended is set as the effective detection time, and when the ball detection device detects a game ball during the effective detection time, a predetermined prize ball Control to generate morphology,
When the ball detection device detects a game ball during an invalid time other than the valid detection time, it is controlled so as not to generate a prize ball form (claim 1). Here, the variable winning a prize is to generate a prize ball form that provides a large profit compared to other winning a prizes, for example, a large winning a prize which is opened when a game state of "hit" is established. is there.

In such a configuration, the effective detection time is set from the start to the end of the special game operation controlled and executed by the prize ball control means, and the game ball detected by the ball detection device during the effective detection time is normal. It is determined that the game ball is generated, and the game ball detected at the invalid time other than the valid detection time is judged to be abnormal and the prize ball form is not generated. As a result, regardless of the prize ball control means for executing the special game operation, the variable winning opening is illegally opened, and the prize ball form does not occur even if the game ball flows in. It is possible to prevent the profit from being provided to the fraudulent player. In addition, it is illegal such as inserting a wire etc. from the gap of the front frame to open the variable winning port to allow the game ball to flow in, or removing the transparent plate to directly insert the game ball into the variable winning port. Actions can be prevented and the soundness of pachinko games can be properly maintained. As described above, according to the present invention, the profit provision, which is a cause of fraudulent activity, is controlled so as not to be performed outside the normal valid detection time. Since the act of trying to generate a form is wasted, the effect of reducing emotions leading to fraud is high.

Such a pachinko gaming machine is provided with an abnormality notifying device for notifying that the detection is abnormal when the ball detecting device detects a game ball at an invalid time other than the valid detecting time ( Claim 2) is proposed. Here, as the abnormality notification device, an acoustic device that notifies abnormal detection by a predetermined sound, an illumination device that notifies by a predetermined light, or the like can be used. It is desirable that such abnormality detection by the abnormality notification device be configured so that a staff member or the like of the game arcade can easily know it. For example, as the abnormality notification device, an illuminating device may be arranged on the upper front surface of the pachinko gaming machine, and the illuminating device may be configured to light up and blink with strong light different from other illuminating devices. With such a configuration, the clerk of the amusement hall and other players can know the illegal act of illegally opening the variable winning a prize and trying to make a profit,
The fraudulent activity can be easily found. As described above, in the present invention, the ball detection device functions as a switch that generates a prize ball form during the effective detection time, and functions as a switch that detects an abnormality due to fraud during the invalid time other than the effective detection time. It will be used as having a function. Thus, a person who tries to commit cheating will not only be able to profit from the cheating, but will also be discovered, which will have the effect of refraining from conducting the cheating, and the health of the amusement hall will be improved. The property is further improved.

A structure is proposed in which the above-mentioned effective detection time is an opening time from execution of control for opening the variable winning opening to execution of control for closing the variable winning opening in the open state (claim 3). To be done. Generally, in the special game operation, the variable winning opening is controlled so as to execute an opening round in which opening and closing operations are repeated. In such a configuration, by setting the effective detection time for each opening round of the variable winning opening, the effective detection time is accurately controlled as the open state of the variable winning opening,
Even when the special game is in operation, when the variable winning a prize opening is closed, the time becomes invalid, and the valid detection time becomes more valid.
As a result, for example, in a special game operation in which the variable winning opening is opened and closed a plurality of times, the variable winning opening is kept open illegally so as not to be closed, and more game balls are flowed in and a large amount of It is possible to prevent fraudulent activities that seek profits.

It is proposed that the award ball control means described above keeps the effective detection time for a predetermined time after the closing operation of the variable winning port (claim 4). In such a configuration, for example, before the gaming ball that has flowed in immediately before the variable winning opening is closed is detected by the ball detection device, the valid detection time ends and it is determined that the detection is abnormal, etc. This prevents the player from suffering a disadvantage when the regular game is judged to be abnormal. Therefore, it can be determined that the gaming balls detected during the period other than the effective detection time according to the present invention are almost abnormal. Here, it is preferable to set the continuous time within a range of about 2 seconds or less.

A configuration is proposed in which the prize ball control means as described above is provided with an allowance and withdrawal device for operating the generation of a predetermined prize ball form during an invalid time other than the valid detection time (claim 5). It With such a configuration, in a situation where the game is being played normally, if the prize balls cannot be paid out due to inconvenience on the pachinko gaming machine side, the staff at the amusement hall will notify the player even outside the effective detection time. It is designed to be able to supplement the prize balls originally received. As a result, the disadvantages caused by the inconvenience of the pachinko gaming machine can be appropriately provided to the player,
The usefulness of the prize ball control means for setting the effective detection time of the present invention is further improved. Here, as the permissible withdrawing device, it is possible to use various devices such as a button switch that is turned on, a switch that is turned on and off, and a switch that is turned. It should be noted that it is preferable that the allowance and withdrawal device is arranged in a place where the player cannot easily operate it. For example, it may be provided on the back surface of the gaming machine main body. In addition, the following configurations can also be adopted.

A configuration (claim 6) in which such an acceptable dispensing device is arranged on a game board is proposed.
In such a configuration, when supplementing the prize balls, the clerk of the game hall opened the door holding the transparent plate arranged on the front of the game board of the pachinko game machine, and was provided on the game board. By operating the allowance and withdrawal device, prize balls will be provided. As described above, since the allowance and withdrawal device is provided on the game board, the game staff can operate it relatively easily, and the player cannot operate it. To be kept. In addition, since the player can recognize the allowable payout device provided on the game board, even if the prize ball is not provided due to the game ball being clogged in the variable winning port, the staff will not be rushed. It also has the effect of implying that you will be able to make an appropriate profit if you contact them.

2, and the symbol display control board 62 displays the defect according to the control command.

Next, the symbol control of the symbol display device 6 will be described again in detail. The special random number K consisting of 630 frames 0 to 629 is stored in the storage device ROM of the main control board 60 described above. This special symbol K is K =
If you choose 7,337, you win. That is, the winning probability is 2/630 = 1/315. And other than that, it will be lost. Then, when K has selected the hit, the hit symbol random number L determines the hit symbol aspect of any of "0" to "9". In addition, when the hit symbol random number L selects a predetermined hit symbol mode,
After the hit ends, a high probability state in which the hit probability of the hit special symbol K is increased until the next hit occurs, a so-called probability variation game state is executed. Furthermore, in this probability variation game state,
It becomes a time-saving game state in which the time required for symbol determination is shortened from the start of variation of the special symbols A, B, C, and an advantageous game state for the player.

Next, the normal symbol operation will be described. When the game ball passes through the normal symbol starting gate 13, the game ball is detected by the normal symbol starting switch S2. When the game ball is detected by this normal symbol starting switch S2, the normal symbol of the normal symbol display device 10 changes. This normal pattern is composed of three light emitting diodes LED of red, middle green and right red. When this normal symbol display device 10 is changing or the normal electric accessory 15 is open, when the game ball is detected by the normal symbol start switch S2, the light emitting diode LED of the normal symbol start memory number display device 12 is the maximum. It lights up to four memory numbers, and is usually turned off every time the pattern starts to change,
The number of stored items is displayed. It should be noted that the maximum storage number of four or more is invalid.

In this way, with the ON operation of the normal symbol starting switch S2, the main control board 60 selects the random number U of the ordinary hit from the storage device ROM and the random number of the ordinary random symbol V of the hit, and the contents thereof once. It is stored in the storage device RAM, and at the same time when the normal symbol display device 10 starts to change, the stored contents are examined and the hit loss corresponding to the selected value of the normal hit random number U is determined. Then, in the case of a hit, the stop mode is determined by the hit random symbol random number V, and at least one of the left red color and the right red color is lit. In the case of loss, only the medium green light emitting diode LED is turned on.

Next, the essential part of the present invention will be described. As described above, the main control board 60 is the special symbol starting switch S1.
When the hit special random number K selected by the ON operation of is a hit, the special symbols A, B, and C are confirmed and displayed in a predetermined hit symbol mode. After that, the main control board 60 drives and controls the special winning opening solenoid via the board relay board 61 to open / close the special winning opening 23 and control the special game operation. In the present embodiment, the effective detection time is set from the execution of the control for starting the special game operation to about 2 seconds after the execution of the control for ending the special game operation.
Then, during this effective detection time, the specific area switch S3 and the count switch S4 provided inside the special winning opening 23 are provided.
When (see FIG. 4) detects a game ball, the main control board 60 executes control for paying out a prize ball. In addition, even if S3 and S4 detect a game ball other than the effective detection time, the main control board 60
Does not execute the control for paying out prize balls.

The main control board 60 includes a storage device RAM.
In addition, a valid flag G indicating a valid detection time for validating the detection of the specific area switch S3 and the count switch S4 arranged inside the special winning opening 23 is set. The valid flag G is controlled so as to show G = 1 during the valid detection time and G = 0 during the invalid time other than the valid detection time. That is, in the normal game state, the valid flag G = 0, and the hit occurs, and the first special winning opening 23
In synchronization with the transmission of a control signal for driving the special winning opening solenoid for opening the
Set to 1. After that, the opening and closing round of the special winning opening 23 progresses, and 10 game balls flowing into the big winning opening 23 in the open state are detected, or the specific state is reached before the open state reaches 30 seconds. When the switch S3 does not detect the game ball, the main control board 60 drives the special winning opening solenoid to close the special winning opening 23. And
The special game operation is ended by the opening / closing round.
Here, the main control board 60 starts time measurement by the timer TM in synchronization with the transmission of the control signal for driving the special winning opening solenoid, and sets the valid flag G = 0 after about 2 seconds. When the opening / closing round of the special winning opening 23 reaches the final round, S3 and S4 detect the inflow of 10 game balls, or when the open state has passed for 30 seconds,
The main control board 60 closes the special winning opening 23 to end the special game operation. Then, about 2 seconds after the control signal for driving the special winning opening solenoid, the valid flag G is set to 0.

On the other hand, above the game board 3 of the pachinko gaming machine 1, a normality notifying device 40 for notifying the normal payout of prize balls is arranged on the left side (see FIG. 1). The normality notification device 40 is composed of a light emitting diode LED, a lamp, or the like, and is turned on every time a prize ball is normally paid out in accordance with a game ball that has flown into the special winning opening 23. That is, in the valid detection time of the valid flag G = 1, the main control board 60 executes the payout control of the prize balls and the light source control in accordance with the game ball detected by the specific area switch S3 or the count switch S4. A control command signal for lighting the normality notification device 40 is transmitted to the substrate 64. Upon receiving the control command signal, the light source control board 64 causes the light emitting diode LED or the lamp of the normality notification device 40 to emit light.

On the right side of the normality notification device 40,
An abnormality notification device 41 is provided to notify the abnormal detection when the specific area switch S3 or the count switch S4 detects a game ball in the invalid time when the valid flag G = 0 (FIG. 1). The abnormality notification device 41 is composed of a light emitting diode LED, a lamp or the like having a different emission color from that of the normality notification device 40, and is configured to emit light strongly at a higher voltage than the normality notification device 40. Then, when S3 or S4 detects a game ball in the invalid time when the special game operation is not executed, the main control board 60 confirms that the valid flag G = 0 and informs the light source control board 64 of the abnormality. A control command signal for blinking the device 41 is transmitted. Upon receiving the control command signal, the light source control board 64 receives the light emitting diode LE of the abnormality notification device 41.
D or a lamp is made to flash. This abnormality notification device 4
By blinking 1, the attendant at the game hall is informed of the occurrence of the abnormality. A stop switch (not shown) for stopping the light emission when the abnormality notification device 41 emits light
Is provided in a place where the player cannot operate, such as the game board and the back of the game machine main body, so that the staff can stop the game after properly treating the abnormality.

Further, at the lower right portion of the game board 3, there is arranged an allowance payout switch (acceptance payout device) 42 capable of paying out prize balls other than the effective detection time (see FIG. 2).
The acceptance / withdrawal switch 42 has a push button type switch structure. The main control board 60 is connected to the main control board 60 via the board relay board 61, and when the acceptance / delivery switch 42 is pressed, the main control board 60 recognizes the ON signal. Then, even in the state of the valid flag G = 0,
The main control board 60 transmits a control command signal for executing the payout of prize balls to the payout control board 65, and the predetermined prize balls are provided. Here, as the prize ball generated by pushing the allowable payout switch 42, the prize ball is 1 in this embodiment.
The prize balls corresponding to one opening and closing round are set to be provided for each pressing operation, so that the player can be compensated with appropriate prize balls. Further, since the allowance and withdrawal switch 42 is provided on the game board 3,
It cannot be operated unless the transparent plate front door 5 is opened. Therefore, the player cannot easily operate it.

Such a prize ball control means is shown in FIGS.
This will be described with reference to the flowchart of FIG. As shown in FIG. 5, when the game ball passes through the special symbol starting area 14, the main control board 60 receives a special random number K, a random symbol L, and a random symbol Ma.
, Mb, Mc, etc. are selected. Then, in the symbol display area F of the symbol display device 6, when the special symbols A, B, C start to change, the main control board 60 determines the hit special random number K selected. Here, when K is selected as a hit, the hit symbol random number L is validated, and according to L, special symbols A, B,
C is stopped in sequence, and is fixedly displayed in a predetermined winning pattern mode.
Then, the special game start delay for notifying that the special game operation is executed is displayed in the symbol display area F. After that, the main control board 60 drives the special winning opening solenoid via the board relay board 61 to open the special winning opening 23, and starts the opening / closing round. In synchronization with this, the valid flag G is set to 1 and the valid detection time is started. Then, when the game ball flows into the open special winning opening 23, the main control board 60 transmits a control command signal for paying out the prize ball to the payout control board 65, as the detection signal of the count switch S4 is received. An award ball will be held appropriately. Further, in synchronization with the payout of the prize balls, a control command signal is transmitted to the light source control board 63 so that the normal control device 40 is turned on.

When the special area switch S3 detects a game ball in the open state of the special winning opening 23 as described above, the transition condition to the next round is satisfied as described above, and the main control board 60 receives the big winning. The mouth solenoid is driven to close the special winning opening 23. After that, the main control board 60 again drives the special winning opening solenoid to open the special winning opening 23. In this way, the opening and closing round of the special winning opening 23 is S
It is repeated until either 3 does not detect the game ball or the maximum round is reached. Then, according to the effective detection time of the effective flag G = 1, the special winning opening 23
The prize balls are paid out in accordance with the game balls that have flown into.

Here, in the open state of the special winning opening 23, 30 seconds have elapsed from the opening operation without the specific area switch S3 detecting the game ball, or the count switch S4 has 10 games. When the ball is detected, the main control board 60 drives the special winning opening solenoid to close the special winning opening 23 and end the special game operation. Then, the special game end delay for notifying the end of the special game operation is effected in the symbol display area F via the symbol control board 64. Further, the main control board 60 starts time measurement by the timer TM in synchronization with driving the special winning opening solenoid, and sets the valid flag G to G = 0 after about 2 seconds have elapsed. This ends the effective detection time.

Further, when the transition condition of the open / close round is satisfied and the maximum round is advanced, 30 seconds elapse from the opening operation of the maximum round, or the specific area switch S3 and the count switch S4 are set to 10 pieces. When the game ball is detected, the main control board 60 drives the special winning opening solenoid to close the special winning opening 23 and end the special game operation. Then, a special game end delay for notifying the end of the special game operation is executed in the symbol display area F. The main control board 60 sets the valid flag G = 0 about 2 seconds after the special winning opening solenoid is driven, and ends the valid detection time. In this way, since the effective detection time is set according to the control of the opening / closing operation of the special winning opening 23 by the main control board 60, an appropriate prize ball is provided to the player during the execution of the special game operation. To be done.

On the other hand, as shown in FIG. 6, it is assumed that a fraudulent act of illegally opening the special winning opening 23 and making a profit is performed in a normal game state regardless of the special game operation. For example, when the special winning opening 23 is opened from the gap of the front frame 2 with a wire or the like and the game ball is launched toward the special winning opening 23, the specific area switch S3 or the count switch S4 detects the game ball. Then, the main control board 60, which has obtained the detection signal, confirms that the valid flag G = 0 and determines that the detection is abnormal. Then, the main control board 60 does not issue a control command signal for paying out prize balls,
A control command signal for operating the abnormality control device 41 is transmitted to the light source control board 63. Then, the light source control board 63
Blinks (or lights) the abnormality control device 41 in a predetermined light emission mode to notify the abnormality. As a result, the profit can be prevented from being provided by such an illegal act, and the staff can properly respond to the illegal act by the notification of the abnormality notification device 41. Moreover, even if the transparent front door 5 is illegally opened and the game ball directly flows into the special winning opening 23, the prize ball is not paid out and the abnormality is notified by the abnormality notification device 41. Becomes Thus, in the game state other than the valid detection time, the valid flag G = 0, so that no prize balls are paid out, and it is possible to prevent the game hall from being disadvantaged by such an illegal act. it can.

Also, in a game situation in which the opening and closing round of the special game operation which is activated by the occurrence of a regular hit is in progress, if the game ball is clogged in the special winning opening 23, the special winning opening 23 will not operate. In some cases. When the special winning opening 23 does not operate in this way, the player will immediately notify the staff, but when the staff arrives, the special game operation ends, and the player has sufficient prize balls. Could not be earned and could suffer disadvantages. In such cases,
The clerk opens the transparent front door 5 with a predetermined key or the like, and pushes and operates the allowable payout switch 42 arranged on the game board 3. The main control board 60, which has received the operation signal of the allowance and withdrawal switch 42, issues a prize ball corresponding to one round of the special winning opening 23 even if the valid flag G = 0. The signal is transmitted to the payout control board 65.
Then, according to the control command signal, the payout control board 65 controls the operation of the prize ball solenoid to execute the prize ball payout.
By operating the payout switch 42 a predetermined number of times,
It is possible to provide a profit that appropriately compensates the disadvantage received by the player.

In the embodiment described above, the effective detection time is controlled from the execution of the control for opening the first special winning opening 23 of the special game operation to the closing operation of the last special winning opening 23. However, it is possible to set the time from the execution of the control for opening the respective special winning openings 23 to the execution of the control for closing the same. Further, the effective detection time may be set in consideration of the control signal transmitted from the main control board 60 and the time lag between the opening operation and the closing operation of the special winning opening 23.
Thereby, the effective detection time can be further matched with the open state of the special winning opening 23.

Further, in the above-mentioned embodiment, the allowance and withdrawal switch 42 is arranged on the game board 3 by a button type switch, but as another example, it is constituted by an ON-OFF switch, a key switch or the like. You can also Among them, by using a key switch, the allowable payout switch 4
Since it is possible to prevent an attempt to illegally operate the item 2, the significance of the allowance and withdrawal switch 42 is further improved. Further, such an allowable payout switch 42 may be arranged on the back surface of the gaming machine main body, or may be arranged in a different place from the pachinko gaming machine. This also makes it possible to prevent the fraudulent payout switch 42 from being fraudulent. Further, the amount of prize balls paid out by operating the allowance payout switch 42 is
In addition to the setting corresponding to one opening / closing round as described above, various settings can be made. For example, prize balls may be continuously paid out at a predetermined rate during the operation. Alternatively, the main control board 60 stores the time when the game ball detection of the count switch S4 is stopped, and the prize ball amount set by the number of rounds when the detection signal is stopped is paid out by operating the allowance payout switch 42. Can also be

Although the above-described embodiment has a configuration in which the illegal payout of the special winning opening is controlled, in addition, the misconducting of other variable winning opening that is opened and closed depending on the establishment of a specific game state is prevented. It is also possible to adopt a configuration that does. Further, in a pachinko gaming machine provided with a plurality of variable winning a prize holes, it is preferable to prevent fraudulent acts on the respective variable winning a prize holes.

The present invention is not limited to the above-mentioned first-class pachinko gaming machine, but the second-class pachinko gaming machine, the third-class pachinko gaming machine, etc. are opened and closed under the condition that they are in a specific gaming state. It is also applicable to other game machines having a variable winning port.
