Description

  The present invention relates to a pachinko gaming machine capable of preventing fraudulent acts for gaining illegal profits.

  As one of fraudulent acts performed in a pachinko gaming machine, there is known a technique for guiding a game ball through a front glass by a magnet to a winning opening that starts changing a selected symbol by passing a game ball. There is also known a configuration in which a variable prize device provided with a movable wing piece that opens and closes is provided at the prize opening. In this case, a front surface is provided by a magnet at a position above the prize opening (variable prize device). There is also a technique in which a large amount of game balls are sucked and held through the glass, and the game balls held at the timing when the movable wing piece is driven to open are dropped at once and awarded.

  Conventionally, as a means for preventing fraud by using such a magnet, one using a reed switch is known. This is a blind end-shaped mounting hole formed on the back surface of the gaming board corresponding to the upper position of the winning hole arranged in the gaming board, and a reed switch is accommodated in the mounting hole. When the reed switch is closed, an alarm buzzer and an alarm lamp are activated immediately (see Patent Document 1).

  In addition to the magnets described above, various other acts have been reported as fraud, such as vibrating a gaming machine or inserting a thin plate through a gap in the gaming machine. A configuration in which a sensor is provided to operate an alarm buzzer as described above is common.

Japanese Utility Model Publication No. 54-119476

  By the way, in the prior art described in the above-mentioned Patent Document 1, when the reed switch detects a magnet, an alarm buzzer or alarm lamp can be activated to notify the fraud. Even if the alarm lamp is activated, there is no change in the game operation itself of the pachinko machine. Therefore, even when the alarm buzzer or warning lamp is in operation, payout of prize balls or transition to the hit gaming state that is advantageous to the player is performed as usual, so profits from fraudulent acts occur, and fraudulent acts are substantially invalidated. There is a problem that cannot be done. In addition, even if an alarm buzzer or alarm lamp is activated by detecting a fraudulent activity, if the fraudster claims that it is malfunctioning and denies the fraudulent act, the amusement store directly uses the magnet by the fraudster. Unless confirmed, often no further pursuit is possible. In addition, troubles may occur with fraudsters, which may cause damage to the game store. From the above, it is not effective fraud prevention means simply by reporting fraud. This is a problem common to fraud other than magnets.

  The present invention proposes a pachinko gaming machine that can eliminate such conventional problems and reliably prevent fraud.

  The present invention supplies a game ball one by one from a game ball storage tray to a launch position at the lower end on the launch rail, and launches the game ball at the launch position, and is disposed on the front side of the game board The winning symbol display device for variably displaying the selected symbol, a winning opening provided on the front side of the game board and detecting the passage of the game ball, and a ball detecting means for the winning opening. Game control means for generating start memory each time a ball is detected and digesting the start memory to start changing the selected symbol on the symbol display device and determine a hit or a miss according to the stop symbol mode The pachinko gaming machine includes a fraud detection sensor that detects fraud and transmits a fraud detection signal, and the game control means is configured to disengage the game ball in accordance with reception of the fraud detection signal. Control and start It is pachinko machine, characterized in that all of the starting memories of the process of digesting stores are pending stopped and digestion treatment comprises a fraud prevention control content stored and held.

  Here, the selected symbol is for determining a winning or losing according to the stopped symbol pattern stopped after the change, and a special symbol or a normal symbol that is generally set can be applied. Then, only one of the special symbol and the normal symbol may be applied as the selected symbol, or both may be applied as the selected symbol. In addition, as described above, fraud detection is applied to various acts such as an act using a magnet, an action by vibration, an action of inserting a thin plate, and the fraud detection sensor that can appropriately detect each fraud. The For example, a magnetic sensor that detects magnetism generated by a magnet and transmits a fraud detection signal can be applied to fraudulent acts using a magnet. It is preferable that this magnetic sensor is arranged in a game board corresponding to the position above the winning opening. This is because an illegal act of guiding the game ball to the winning opening by the magnet can be reliably detected.

  In such a configuration, when a fraudulent detection is detected by the fraud detection sensor, it becomes impossible to launch the game ball, so that it is possible to prevent the fraud after the detection. However, even if it is impossible to launch the game ball, the illegal act detected by the fraud detection sensor is being executed, and it is also possible to perform the same illegal act on the game ball that has been launched before it is impossible to launch the game ball. It is. On the other hand, in this configuration, even if the game ball flows into the winning opening due to the fraudulent act and the start memory is generated, the profit associated with the start memory is obtained by stopping the start memory digestion process. It is prevented from occurring. As described above, when an illegal act is detected, the game ball cannot be launched and the digestion process of the start memory is stopped, so that the game is substantially interrupted. For this reason, no profit is provided to the person who has performed the fraud, and the fraud is substantially invalidated. Therefore, the fraud can be prevented. And since the profit by fraud is not provided, the amusement shop side does not suffer the disadvantage by fraud.

  Further, in this configuration, when an illegal act is detected, the start memory digestion process is stopped, and the start memory for which the digest process is suspended is stored and held. Here, the start memory to be stored and held is all the start memories that have suspended digestion processing, the start memory that has been suspended before detection of fraud, and the start that occurs after detection of fraud It is memory. As a general function of a pachinko gaming machine, when a game ball continuously flows into the winning opening and a start memory is continuously generated, the start memory is normally held up to a predetermined maximum memory number. Digests sequentially. In other words, all the starting memories that are held in this way are stored and held as described above.

  As described above, if a cheating is detected, all the starting memories that have suspended the digestion process are stored, so even if the cheating is detected due to a malfunction, the game is resumed, By sequentially digesting the stored start memory, the player's profits can be preserved. Therefore, troubles can be prevented from occurring with a healthy player.

  In addition, as control of the launching device which makes it impossible to launch the game ball, control to prevent the game ball from being supplied from the game ball storage dish to the launch position of the launch rail, or to launch (launch) the game ball at the launch position Controls that do not operate the solenoids and motors can be suitably used.

  In the pachinko gaming machine described above, on the back side of the game board, a return switch for transmitting a return signal by an ON operation and a cancel switch for transmitting a cancel signal by an ON operation are disposed, and game control means In accordance with the reception of the return signal, canceling the inability to launch the game ball by the launching device, releasing the stop of the start memory digestion process, and sequentially starting the digestion of the stored start memory, In accordance with reception of the cancel signal, release of the inability to launch the game ball by the launching device is canceled, the stop of the start memory digestion process is canceled, the start memory stored and held before the cancel signal is received, and the cancel is canceled. All start memories stored and held before receiving the signal will be confirmed by the lost symbol pattern of the selected symbol that changes due to its digestion. Configuration is proposed and a loss recovery control content to be processed.

  In such a configuration, a return switch and a cancel switch for resuming the game by canceling the digestion stoppage of the start memory and the inability to fire the game ball generated by the fraud prevention control contents are arranged on the back side of the game board. Since these switches are provided, these switches cannot be operated by players or fraudsters, so resumption of the game must be relied upon by a staff member at the game hall. Then, when a game attendant suspends the game due to the stoppage of the start memory and the inability to launch the game ball, if the cause of the suspend is clearly determined to be fraudulent, the cancel switch is turned ON. As a result, all starting memories that are stored and held are forcibly lost due to the digestion process, so that no profit is provided by fraud before restarting the game. As described above, since the profit due to the fraud does not occur even when the game is resumed, the effect of substantially preventing the fraud is further improved.

  Here, as a process to forcibly lose all the start memories that are stored and held, when digesting each start memory, it is determined that it is lost without performing a hit or lose determination, In the process of performing control to fluctuate and stop the selected symbol according to the loss, or when digesting each start memory, it is determined whether the start memory is a hit or a lose, and if it is a win, it is replaced with a lose It is possible to use any of the processes for confirming and controlling the selected symbols to fluctuate and stop according to the loss.

  On the other hand, when it is recognized that the cause of the above-mentioned game interruption is apparently a malfunction, the player can resume the game by turning on the return switch. At this time, since the start-up memory stored in memory is digested as usual, a healthy player is not disadvantaged and trouble with the player does not occur.

  Furthermore, since the return switch and the cancel switch are disposed on the back side of the game board, it is difficult for the player to determine which switch to operate when operating by a game attendant or the like. Furthermore, since the return control content and the loss return control content differ only in the control inside the gaming machine, the game proceeds similarly on the surface. For this reason, the fraudulent person does not know that the loss recovery control content forcing the loss due to the digestion of the start memory is being executed. Therefore, according to the present configuration, as described above, not only can the profit to the fraudster be prevented, but also the effect of preventing troubles between the game hall side and the fraudster is excellent.

  In the pachinko gaming machine described above, the game control means sets a predetermined invalid time or an invalid number of game balls to be fired by the launching device according to the reception of the cancel signal, and until the invalid time elapses. Or a configuration with fraud penalty control content that processes all start memories that occurred until the number of invalid fires is reached so that the stop symbol pattern of the selected symbol that fluctuates due to its digestion is determined by the lost symbol is proposed Is done. Here, the invalid time starts the time digestion when the cancel signal is received, and as a method of measuring the invalid time (method of time digestion), either the time measurement by the timer or the measurement by the counter is used. It may be used. Further, the number of invalid shots is measured by starting counting the number of game balls launched by the launch device when a cancel signal is received.

  In such a configuration, control is performed so as to forcibly lose all starting memories that occurred during a predetermined period, even after resuming the game as described above, for those who have performed fraud. , Penalize fraudsters. In this case, the game ball fired by the fraudulent person becomes a waste ball substantially, so a relatively severe penalty is imposed. This further improves the effect of preventing fraud.

  In addition, if a fraudulent person leaves the gaming machine after resuming the game, a healthy player who uses the gaming machine may incur the above penalty, so the fraud penalty control content is canceled. It is preferable to provide a switch or the like. In addition, if the invalid penalty control content is set to a shorter invalid time than the time required for the player to change, the next healthy player is charged to the previous fraudster. It can prevent taking a penalty.

  As described above, when the pachinko gaming machine of the present invention receives a fraud detection signal transmitted by detecting a fraudulent act from the fraud detection sensor, the game control means sets the launching device so that the game ball cannot be launched. Since it is configured to execute the anti-fraud control contents to stop and stop the process of digesting the start memory and to store all the start memories that have suspended the digest process, Since the game ball cannot be fired and the digestion process of the start memory is stopped, the game is substantially interrupted, and no profit is provided by the fraud. Therefore, the fraud can be prevented. In addition, since the start-up memory that holds the digestion process is stored, even if the detection of fraud is caused by a malfunction, if the game is resumed, the profits of a healthy player are preserved. be able to.

  In the pachinko gaming machine described above, in accordance with the ON operation of the return switch disposed on the back side of the game board, the inability to release the game ball is released and the stop of the digestion process of the start memory is released and stored. In accordance with the contents of the return control that sequentially starts the digestion of the start memory and the ON operation of the cancel switch arranged on the back side of the game board, the inability to fire the game ball is canceled and the stop of the start memory digest process is canceled. In this manner, the start memory stored and held before the ON operation is sequentially digested, and all the start memories stored and retained are processed so that the stop symbol pattern of the selected symbol that changes due to the digest is determined by the lose symbol. If the cause of the game interruption is clearly recognized as a fraudulent act, the memory is retained by turning on the cancel switch. Since all of the starting memory which there is loss, since the benefits of cheating before resuming after game restart is not granted, it can be substantially prevented abuse. In addition, it is difficult for the player (a fraudulent person) to confirm the operation of turning on the return switch or the cancel switch, and the game is resumed on the surface with any of the on actions. If it is recognized, only turning on the cancel switch avoids preventing troubles between the amusement shop side and the fraudulent person, and does not provide the profit due to the fraudulent act.

  In the pachinko gaming machine described above, according to the ON operation of the cancel switch, the invalid time or the invalid number of game balls is set, and all start memories that have occurred until the invalid time elapses or the invalid number of fires are reached are digested. In the configuration with fraud penalty control content that processes the stop symbol pattern of the selected symbol that fluctuates according to the loss symbol, the profit by winning for a certain period after the game resumes By preventing the occurrence of the problem and imposing a severe penalty of digesting the waste balls, the effect of preventing fraud can be further improved.

Next, the control mode by the control circuit shown in FIG. 8 will be described according to the operation of the pachinko gaming machine.
In accordance with the operation of the launch lever 27 described above, the game ball x supplied to the launch position P by the rectifier 22 is launched into the game area 12 by the bullet ball device 21. When the game ball x passes through the normal symbol start gate 49 and the normal symbol start switch S2 is turned on, the main control board 80 performs normal symbol start processing. That is, the central control unit CPU of the main control board 80, which has recognized the ON operation signal of the normal symbol start switch S2, performs a normal hit by drawing from the normal hit random number table and the normal hit symbol random number table stored in the storage device ROM. A random number value and a normal hit design random number value are selected, respectively, and these random number values are temporarily stored in the storage device RAM as a set of normal design start memory. When the game ball passes continuously through the normal symbol start gates 49, 49, the normal symbol start memory consisting of the random number value selected based on the ON operation of the normal symbol start switch S2 is mainly stored in the order of occurrence. Each is stored in the storage device RAM of the control board 80. Then, the stored number of the normal symbol start memory is stored in the storage device RAM of the main control board 80, and the light emitting diodes of the normal symbol start memory number display device 47 are sequentially turned on according to the start memory number as described above. The maximum number of normal symbol starting memories is displayed. The light emitting diode is turned off every time the normal symbols E1 and E2 on the display screen 43 start to fluctuate, and the normal symbol start memory number decreases. When the number of normal symbol starting memories is full (four), even if the game ball x passes through the normal symbol starting gates 49, 49, it becomes invalid.

  When the normal symbol start memory is stored in the storage device RAM, the main control board 80 performs the normal symbol start memory digestion process in the order of occurrence. That is, the normal symbol start memory is read, one light emitting diode of the normal symbol start memory number display device 47 is turned off, the symbol fluctuations of the normal symbols E1 and E2 are started, and the normal random number value of the normal symbol start memory is determined. Based on the result, a symbol control command signal for controlling the normal symbol display mode displayed on the display screen 43 of the symbol display device 42 is transmitted to the effect control board 82. Here, when the normal hit random number value is a predetermined hit random number value, the effect control board 82 stops the normal symbols E1 and E2 at the hit symbol according to the normal hit symbol random number value and displays the final symbol. Then, when the normal symbols E1 and E2 are confirmed and displayed in the hit mode, the main control board 80 performs a process of moving the variable winning device 51. That is, the main control board 80 drives the ordinary electric accessory solenoid 56 via the board relay board, and the movable wing pieces 52 and 52 of the variable prize winning device 51 are outwardly shaped in a reverse C shape for a predetermined time (for example, 0.2 seconds). To expand to the tilt position. As a result, it becomes easy for a game ball to enter the winning opening 54. On the other hand, when the normal random number value is a predetermined loss random value, the effect control board 82 stops the normal symbols E1 and E2 at the lost symbol and displays the final symbols.

  As described above, a maximum of four normal symbol start memories are stored, and the digestion process is performed in the order of occurrence. Therefore, the normal symbol start memory before the digestion process is in a state where the digestion process is suspended. is there.

  On the other hand, when the game ball fired by the bullet ball device 21 rolls down the game area 12 and flows into the winning opening 54, the special symbol start switch S1 is turned on as shown in FIG. 9, and the signal is recognized. The main control board 80 performs the process (special symbol start storage process) of extracting each random number value and storing the special symbol start memory. That is, the central control unit CPU of the main control board 80 selects the big hit random number value, the big hit symbol random number value or the like by lottery from the big hit special random number table, the big hit symbol random number table, the lost symbol random number table, etc. stored in the storage device ROM. Lost symbol random numbers and the like are extracted, and each random number is temporarily stored in the storage device RAM as a set of special symbol start memories. When the game ball x continuously flows into the winning opening 54, as in the case of the normal symbol start memory described above, the random number values drawn based on the ON operation of the special symbol start switch S1 are used. The special symbol start memory is stored in the storage device RAM of the main control board 80 in the order of occurrence, and the number of stored special symbol start memories is stored in the storage device RAM of the main control board 80, and the special symbol start memory number display The light-emitting diodes of the device 46 are sequentially turned on according to the starting memory number, and display up to four special symbol starting memory numbers. The light emitting diode is turned off every time the special symbols A, B, and C on the display screen 43 start to fluctuate, and the number of special symbol starting memories decreases. If the number of special symbol starting memories is full (four), even if a game ball flows into the winning opening 54, it becomes invalid.

  Then, when the special symbol start memory is stored in the storage device RAM, the main control board 80, as shown in FIG. 10, digests the special symbol start memory in the order of occurrence, and controls the special symbol to be varied. I do. That is, the special symbol starting memory is read, one light emitting diode of the special symbol starting memory number display device 46 is turned off, the symbol variation of the special symbols A, B and C is started, and the jackpot random number value of the special symbol starting memory is calculated. judge. Here, if it is a big hit, a big hit symbol random number value is selected and a winning symbol is selected, and a winning symbol variation pattern displayed on the symbol display device 42 is selected according to the other random number values. Perform symbol processing. As a result, the symbol display step 42 produces and displays a symbol generation process in which the special symbols A, B, and C are hit and confirmed and stopped in the symbol mode. Thus, when the winning is made in this way, as described above, the big hit round for opening and closing the big winning opening 61 is started. On the other hand, if the big hit random number value is a lost random value, the lost symbol random value is selected to select the lost symbol, the lost symbol variation pattern is selected, and the effect control board 82 executes the lost symbol processing. . As a result, the special symbols A, B, and C are confirmed and displayed as lost symbols on the symbol display device 42.

  Even in the special symbol start memory, the maximum four symbols are stored in the same manner as the normal symbol start memory described above, and the digestion process is performed in the order of generation. The digestion process is suspended.

  In the present embodiment, as described above, the process of digesting the special symbol start memory has been mainly described. However, other processes (for example, the main process) can be executed in the same manner as the conventional configuration. Therefore, the details are omitted as appropriate.

Next, the main part of the present invention will be described.
Inside the game board 8 corresponding to the left and right upper positions of the winning opening 54 (variable winning apparatus 51), as shown in FIG. 5A, the magnetism generated by the magnet 100 is detected and a fraud detection signal is transmitted. Magnetic sensors 91 and 91 each composed of a reed switch are provided. As shown in FIG. 5B, each of the magnetic sensors 91 and 91 does not penetrate from the back surface of the game board 8 to the front surface side while being fitted in a substantially cylindrical holding member 92 made of an elastic body such as rubber. It is inserted and held in a blind end mounting hole 93 formed so as to be close to the surface side. Here, the reed switch as the magnetic sensor 91 has a characteristic of detecting the magnetism generated by the magnet 100 with the highest sensitivity when the N pole or S pole of the magnet 100 is located on one end side in the longitudinal direction. Thus, a magnet that can be brought close to the front glass 14 by disposing the reed switch as the magnetic sensor 91 perpendicular to the game board 8 and having one end in the longitudinal direction facing the front glass 14. 100 N poles or S poles can be detected with high sensitivity. In addition, by inserting and holding the magnetic sensor 91 in the blind-end mounting hole 93 in this way, the magnetic sensor 91 can be made invisible from the surface side of the game board 8 and the surface of the game board 8 Since the design applied to the game board 8 is not spoiled, it is possible to prevent the external aesthetics of the game board 8 from being deteriorated. As the magnetic sensor 91, a magnetically sensitive semiconductor element such as a Hall element, MR (magnetoresistive) element, MI (magnetic impedance) element or the like can be used in addition to the illustrated reed switch.

  The magnetic sensor 91 is connected to the input port of the main control board 80 via a panel relay board (see FIG. 8). When the magnetic sensor 91 detects magnetism by the magnet 100, it transmits a fraud detection signal and the signal is input to the main control board 80.

  Further, as shown in FIG. 4, the back mechanism plate 7 disposed on the back side of the game board 8 is provided with a return switch 96 including a button switch and a cancel switch 97. Even in the return switch 96 and the cancel switch 97, they are connected to the input port of the main control board 80 via the panel relay board (see FIG. 8). The return switch 96 transmits a return signal when the switch is turned on, and the cancel switch 97 transmits a cancel signal when the switch is turned on. Each signal is input to the main control board 80.

  On the other hand, the storage device ROM of the main control board 80 stores and holds a fraud prevention control program that is executed in response to the input of the fraud detection signal described above. By executing this fraud prevention control program, fraud prevention control is performed. Processing (see FIG. 11) is performed. The fraud prevention control contents, the return control contents, the loss return control contents, and the fraud penalty control contents according to the present invention are constituted by the above-described fraud prevention control process, the above-described winning a prize opening process, and special symbol process.

Below, the control aspect performed with the magnetic detection by the magnetic sensor 91 is demonstrated.
When the fraud detection signal is received by the main control board 80 as described above, the fraud prevention control process (contents of fraud prevention control) is executed by the fraud prevention control program as shown in FIG. The firing stop process for stopping each drive of the above and the control for stopping the digestion process of the normal symbol start memory and the special symbol start memory described above are performed. More specifically, when the fraud detection signal is input from the magnetic sensor 91 described above, the main control board 80 reads the fraud prevention control program, executes interrupt processing, and executes firing stop processing. In this firing stop process, a firing stop command signal is transmitted from the main control board 80 to the launch control board 84, and the launch control board 84 that has received the launch stop command signal receives a detection signal from the rotation angle detection sensor of the launch lever 27. Even if it inputs, it controls so that the signal which drives the solenoid 37 for ball feeding of the rectifier 22 and the solenoid 25 for launching of the bullet ball apparatus 21 may not be transmitted. As a result, the launching rod 24 of the bullet ball device 21 is not driven and the ball feeding member 32 of the rectifier 22 is not rotated, so that the game ball x cannot be launched and the game ball x is not supplied to the launch position P. , The game ball x is disabled to fire.

  Further, the normal symbol start memory and the digest processing of the special symbol start memory are stopped by the fraud prevention control program. Specifically, as shown in FIG. 11, the digestion execution flag = 1 is set by the fraud prevention control process. Accordingly, in the case of the special symbol process of FIG. 10, the digestion execution flag = 1 even if the start memory is stored. Therefore, the process of digesting the special symbol start memory is not performed. Thus, in the special symbol process, if the digest execution flag = 1, the special symbol start memory is not read, and the substantial digest process is stopped. And all the special symbol starting memories which have suspended the digestion process are stored and maintained in the storage device RAM. On the other hand, since the winning opening process is continuously executed, if the gaming ball x that has been launched before the gaming ball x cannot be fired flows into the winning opening 54, a new special symbol start memory is generated. The special symbol start memory is stored in the storage device RAM and held. Since the special symbol start memory digestion process is stopped as described above, the special symbol A, B, C is not started to change in the symbol display device 42. Normally, the digest execution flag = 0, and in this case, the special symbol process is continuously executed as described above.

  In this embodiment, when the digestion execution flag is set to 1 by the above-described fraud prevention control process, the digest process of the normal symbol start memory is also stopped similarly to the digest process of the special symbol start memory (not shown). . Then, the normal symbol start memory holding the digestion process is stored and maintained in the storage device RAM, and the fluctuations of the normal symbols E1 and E2 are not started.

  In this way, the gaming ball x cannot be launched by the fraud prevention control process, and the special symbol start memory and the normal symbol start memory digestion process are stopped, and the special symbols A, B, C and the normal symbols E1, E2 are stopped. Since the change of the game does not start, the game is substantially interrupted. That is, when an illegal act of guiding the game ball x to the winning port 54 using the magnet 100 through the front glass 14 is performed, the magnetic sensor 91 detects the magnetism of the magnet 100, so that the game ball x is launched. It becomes impossible and the digestion of the special symbol start memory and the normal symbol start memory stops. Thereby, the profit obtained when the special symbol A, B, C starts to fluctuate based on the inflow of the game ball to the winning port 54 is not provided to the fraudster.

  On the other hand, when the game is interrupted as described above, the fraudulent person prompts the attendant of the game hall to resume the game. It is necessary to turn on the return switch 96 or the cancel switch 97 described above in order to release the game ball x from being disabled and to cancel the digestion stop between the special symbol start memory and the normal symbol start memory. Since the return switch 96 and the cancel switch 97 are arranged on the back mechanism plate 7 as described above, they cannot be operated by an unauthorized person. It can be operated by opening the frame 5 from the outer frame 2.

  Here, when it is recognized that an illegal act using the magnet 100 has been performed, a staff member of the game hall turns on the cancel switch 97 to close the main body frame 5 of the gaming machine main body 3. When the main control board 80 receives the cancel signal transmitted by the ON operation of the cancel switch 97, as shown in FIG. 11, the firing stop canceling process for canceling the driving stop of the bullet device 21 and the rectifier 22, the normal symbol starting memory and Control to resume the digest process of special symbol start memory (losing return control content) is performed. In the firing stop release process, the launch stop release command signal is transmitted from the main control board 80 to the launch control board 84, and the launch control board 84 that has received the launch stop release command signal receives the ball feeding solenoid 37 and the bullet of the rectifier 22. Control is performed so as to cancel the transmission stop of the signal for driving the firing solenoid 25 of the ball device 21. Thereby, the ball feeding solenoid 37 and the firing solenoid 25 are driven in accordance with the input of the detection signal from the rotation angle detection sensor of the launch lever 27, so that the inability to launch the game ball x is released and the game ball x can be launched. It becomes like this.

  Further, the main control board 80 resumes the normal symbol start memory and the special symbol start memory digestion process. More specifically, the above-described digestion execution flag is set to 0, and accordingly, processing for sequentially digesting the special symbol start memory stored in the storage device RAM and held is executed (see FIG. 10). Similarly, the ordinary symbol start memory stored in the storage device RAM and held is sequentially digested. Here, in this embodiment, the special symbol start memory stored before the cancellation signal is received is prevented from being hit. Specifically, as shown in FIG. 11, the special symbol start memorized number stored before reception of the cancel signal is set as the loss confirmation flag. Then, in the special symbol processing, as shown in FIG. 10, before determining the big hit random number value of the special symbol start memory, the loss confirmation flag is confirmed. If the loss confirmation flag is 1 or more, Random value determination is not performed, and a lost symbol random value is selected to execute a lost symbol process, and control is performed so that the loss is forcibly determined. As a result, the special symbol start memory stored before receiving the cancel signal displays the special symbols A, B, and C, which have started to fluctuate based on the digestion, in a definite manner according to the lost symbol random value. In this manner, all special symbol start memories stored before the above-described game interruption are forcibly confirmed by the digestion. During a normal game, the loss determination flag = 0, and as described above, the hit or loss is determined by determining the big hit random value.

  In this embodiment, the normal symbol start memory digestion process is executed as usual. That is, even in the normal symbol start memory stored before the above-described game interruption, the winning or losing is determined, and in the case of winning, control for driving the variable winning device 51 is performed.

  Further, in the present embodiment, when the main control board 80 receives the cancel signal as described above, a control process (contents of illegal penalty control) is performed so as not to generate a big hit for a certain period after the game is resumed. Yes. That is, even when a predetermined invalid time is set and the game ball x flows into the winning opening 54 until the invalid time elapses, a new special symbol start memory is generated within the invalid time. All special symbol start-up memories are processed so that no hit occurs due to the digestion. Specifically, the invalid time is set as 5 minutes by the invalid time process (see FIG. 11), and the invalid time is measured by the timer TM from the game restart (when the digest process of the special symbol start memory is resumed). The invalid flag is set to 1 simultaneously with the start of the invalid time measurement, and the invalid flag is set to 0 when the invalid time has elapsed. When the invalid flag = 1 by this invalid time processing, as shown in FIG. 9, 1 is added to the above-described loss confirmation flag every time the special symbol start memory is generated. Thereby, even in the special symbol start memory generated within the invalid time, as described above, control is performed so that the loss is confirmed by digestion. When the invalid time elapses, the invalid symbol = 0 is set so that the special symbol start memory generated thereafter is digested as usual. Even before the invalid time process is executed, since the invalid flag = 0, the special symbol start memory is digested as usual.

  In this way, according to the ON operation of the cancel switch 97, the special symbol start memory and the normal symbol start memory are digested according to their generation order, and all the memory stored in the storage device RAM before the cancel switch 97 is turned ON is stored. Since the special symbol start memory is forcibly determined to be lost by its digestion, no profit (bonus) due to fraud using the magnet 100 as described above does not occur. Thereby, since the fraud using the magnet 100 is substantially invalidated, the effect of preventing the fraud can be obtained. In addition, because the ON operation of the cancel switch 97, even if there is a special symbol start memory that has occurred between the time when the game is resumed and the time when the invalid time elapses, it is forcibly confirmed by the digestion, The waste ball is consumed substantially during the invalid time. Therefore, the fraudulent person is not only profitable, but also suffers a disadvantage, so the effect of preventing the fraud is further improved.

  On the other hand, when the game is interrupted by the magnetic detection by the magnetic sensor 91 as described above, the game ball x cannot be fired and the digestion process of the special symbol start memory and the normal symbol start memory is stopped. However, if it is clearly recognized as a malfunction, an attendant at the game hall turns on the return switch 96 described above. When the main control board 80 receives the return signal thus transmitted, as shown in FIG. 11, a launch stop canceling process for canceling the inability to launch the game ball x is executed, and the special symbol start memory is set with the digest execution flag = 0. And the digest process of normal symbol start memory is restarted respectively. That is, by the firing stop release process, the stop of signal transmission for driving the ball feeding solenoid 37 of the rectifier 22 and the firing solenoid 25 of the bullet ball device 21 is released, and from the rotation angle detection sensor of the launch lever 27 The solenoids 25 and 37 are driven and controlled in accordance with the detection signal input. Furthermore, the digest processing of the special symbol start memory and the normal symbol start memory stored and held in the storage device RAM is resumed, and each start memory is digested as usual according to the generation order. Here, since the above-mentioned loss confirmation flag = 0 and invalid flag = 0 are maintained, the special symbol start memory is digested as usual, so if a big hit random number value is extracted, it will be accompanied accordingly. The special symbols A, B, and C are stopped at the winning symbol and the big hit is confirmed, and the big hit round that opens and closes the special winning opening 61 is started. For such a healthy player, the normal game is resumed so that there is no disadvantage associated with the interruption. Therefore, it is possible to prevent a trouble from occurring with the player.

  As described above, as the control process executed by each ON operation of the return switch 96 and the cancel switch 97, both perform the firing stop canceling process and set the digest execution flag = 0 to the special symbol start memory and the normal symbol start memory. Resume the digestion process. Therefore, the game is to be resumed similarly by any ON operation, and the control process for confirming the special symbol start memory by the ON operation of the cancel switch 97 is an internal control. A fraudster cannot clearly recognize. In addition, the return switch 96 and the cancel switch 97 are disposed on the back mechanism plate 7 and operated by opening the main body frame 5 of the gaming machine main body 3 from the outer frame 2. Therefore, it is difficult for a fraudulent person to know which switch has been turned on when a clerk at the game hall operates the cancel switch 97 or the return switch 96. From the above, if the game is interrupted by the magnetic detection of the magnetic sensor 91 as described above, if the cause is clearly recognized as an illegal act, for example, it is claimed that the cheating person is malfunctioning. Even so, the cancel switch 97 may be turned on to resume the game. Accordingly, it is possible to prevent profits from being provided to the fraudulent person while avoiding unnecessary troubles such as a dispute between the fraudulent person and the staff of the game hall.

  Further, the invalid time set in accordance with the ON operation of the cancel switch 97 can be determined as appropriate, but it is required that the next player is not disadvantaged by the replacement of the player. For example, if a fraudster stops playing a game on the gaming machine 1 immediately after resuming the game, the special symbol start memory obtained by the next player may be lost. Consider no profits. Therefore, it is preferable that the invalid time is determined in consideration of the time required for changing the player. In this embodiment, since the invalid time is set as 5 minutes, even if the player changes immediately after the game is resumed, the time required for the replacement will be 5 minutes, so the next game The person will not suffer any disadvantages. Needless to say, the invalid time can be controlled so as to be set as appropriate, such as 3 minutes or 10 minutes. Furthermore, the start time of the invalid time can be set variously such as setting the time when the launch lever 27 is first operated after the game is resumed.

  On the other hand, in the above-described embodiment, the stored special symbol start memory is forcibly confirmed by the ON operation of the cancel switch. Similarly, the stored normal symbol is stored. The start memory may be forcibly finalized. Furthermore, the normal symbol start memory generated during the invalid time may be forcibly confirmed. In this way, by performing control processing to confirm the loss of normal symbol start memory, it is possible to further limit the provision of profits for fraudulent acts and to prevent the occurrence of profit provisions to fraudulent persons. Is further improved.

  In the above-described embodiment, the firing stop control process executed by the fraud detection signal is performed by stopping both the ball feeding solenoid of the rectifier and the firing solenoid of the bullet ball device. Only the solenoid for feeding may be stopped. This is because if the supply of the game ball by the rectifier is stopped, the game ball cannot be launched even if the bullet device is driven.

  Further, in the above-described embodiment, the invalid time is set by the ON operation of the cancel switch. However, as another configuration, the number of game balls fired by the bullet device is invalid fired. It is also possible to adopt a configuration in which a special symbol start memory that has been generated before the number of invalid shots is fired is forcibly confirmed. In this case, for example, upon receiving a cancel signal, the number of invalid shots (for example, 100 balls) is set, and the number of shots of the game ball x is counted from the time when driving of the rectifier and the ball apparatus is resumed. When a special symbol start memory is generated before the number of invalid fires reaches the number of invalid fires, a process of adding 1 to the above-described loss confirmation flag is performed for each occurrence. As a result, the special symbol start memory that has been generated from the restart of the game until the number of invalid shots is reached is processed so as to forcibly confirm the loss by the digestion. In addition, as the counting process of the number of game balls to be fired, a process of counting each time the firing solenoid of the bullet ball apparatus is driven, or a sensor is installed at the tip of the launch rail, and the game ball is A process of counting each time it is detected can be performed.

  In the above-described embodiment, the special symbol start memory stored before receiving the cancel signal is used as a control process to forcibly confirm the special symbol start memory in the special symbol processing. Without determining, the loss symbol random value etc. is confirmed and the loss is confirmed, but as other control processing, the big hit random number value is determined, and in the case of a loss, the loss symbol random number value etc. Check and perform the lost symbol processing. If it is a win, convert the big hit random number value to a lost random value (for example, add 1 to the big hit random value), check the lost symbol random value, etc. You may make it perform a symbol process. In this case, only when the big hit random number value is the hit random number value, the control process is performed so as to forcibly determine the loss. Even with such a control process, it is possible to determine all the special symbol starting memories stored before the cancellation signal is received.

  In the above-described embodiment, the invalid time is set according to the ON operation of the cancel switch, and the special symbol start memory generated after the restart is determined to be lost, but the invalid time is not set and occurs after the restart. The special symbol start memory may be performed as usual.

  In this invention, it is not limited to the Example mentioned above, About another structure, it can change suitably within the range of the meaning of this invention. For example, a vibration sensor may be provided, and the fraud prevention control process similar to that described above may be executed in accordance with vibration detection by the vibration sensor. Thereby, fraudulent acts such as hitting a gaming machine can be prevented. Furthermore, you may make it arrange | position both said magnetic sensor and a vibration sensor.
