Description

  The present invention relates to a gaming machine including a first base and a second base that can be opened and closed relative to the first base.

  For example, a pachinko machine that is one of the gaming machines includes an outer frame (first base body) that is formed in a rectangular frame shape that opens forward and backward and is fixed to an installation frame base of a game store, and the outer frame. A game board having a middle frame (second base) as a main body frame that is hinged so that the left and right sides can be opened and closed with respect to the frame, and in which a game area in which pachinko balls can flow is defined Is detachably disposed on the inner frame. Also, on the front side of the middle frame, a front frame (second base) as a decorative frame that decorates the front surface of the pachinko machine and protects the game board from seeing is hingedly connected to one of the left and right sides. Yes. In this type of pachinko machine, a decorative member (so-called center role) formed in a frame shape that opens back and forth is disposed at a substantially central position of the game area defined on the surface of the game board. A design display device such as a liquid crystal type or a drum type that displays a plurality of symbols by variably displaying them through the opening of the game machine is faced from the rear, and a pachinko is placed below the frame-shaped decorative body on the game board. Many proposals have been made that include a start winning part that starts symbol variation in the symbol display device by winning a ball (game ball) and a special winning part that is opened when a winning game occurs.

  In such a pachinko machine, the pachinko ball launched into the game area gradually flows down due to its own weight while bouncing off by contact with a game nail or the like implanted in the game area, and starts in the process of flowing down the game area. A lottery regarding whether or not to generate a winning game is performed by detecting a pachinko ball won in the winning section by a ball detection sensor as a detecting means, and various kinds of reach effects etc. for reporting the lottery result to the player When the game display effect is performed on the symbol display device and a winning game is generated, the symbol display device stops the symbol combination in a predetermined combination to open the special winning portion and acquire a large number of prize balls. Configured to get.

  In recent years, fraudulent acts using radio waves that are erroneously detected by irradiating a strong radio wave toward the ball detection sensor provided corresponding to the start winning part, or a magnet close to the game board by magnetism. A lottery to determine whether or not to win a prize ball or to generate a winning game by misconducting using a magnet that misdetects the sensor or guiding the pachinko ball to any position on the board by its magnetic force A so-called goto action that starts illegally occurs, which is a problem. Therefore, fraud detection means for detecting radio waves and magnetism is provided on the game board, and fraud is detected by the fraud detection means (see, for example, Patent Document 1).

  However, not only the surrounding environment is different for each game store, but also the electronic devices carried by game shop employees and players with the spread of electronic devices such as mobile phones and various information terminals may also affect pachinko machines. The radio wave conditions and magnetic field environment are greatly affected. Also, in recent pachinko machines, in order to improve the fun of the game, the symbol display device composed of a liquid crystal display or the like is enlarged, or not only the display effect on the symbol display device but also a movable effect device. Many proposals have been made to produce effects by the physical operation of a movable body, and changes in radio wave conditions and magnetic field environments accompanying these operations are becoming ignorable. For this reason, there is a concern that it will be difficult to accurately detect the fraudulent acts performed with fraudulent intentions on the pachinko machine.

  That is, the present invention has been proposed to solve this problem in view of the above-described problems inherent in gaming machines according to the prior art, and can effectively detect that an illegal act has been executed. The purpose is to provide a machine.

In order to overcome the above-mentioned problems and achieve the intended purpose, the invention according to claim 1 of the present application provides:
In a gaming machine comprising a second base (12, 13) that can be opened and closed relative to the first base (11),
Power switching means (81) for switching the gaming machine between a power-on state and a power-off state;
Open / close detecting means (112) capable of detecting a relative open state and a closed state of the first base body (11) and the second base body (12, 13);
A fraud detection means (130) configured to output a fraud detection signal based on the detection value configured to fluctuate the detection value when fraud is performed;
The fraud detection means (130) includes a setting means (132) for setting a reference value serving as a reference for outputting a fraud detection signal,
The setting means (132) is configured such that the power switching means (81) is switched to a power-on state and the open / close detection means (112) is connected to the first base (11) and the second base (12, 13). When the relative closed state is detected, the reference value is set, and the first base body (11) and the second base member (81) are in a state where the power switching means (81) is in a power-on state. The gist is that the reference value is set every time the open / close detection means (112) detects that the base body (12, 13) has changed from a relative open state to a closed state.
As described above, when the gaming machine is turned on, the reference for the fraud detection means to output the fraud detection signal when the first and second bases are closed and put into a state of being used for the game. When the setting means sets the reference value to be, a detection state suitable for the installation environment of the gaming machine can be obtained. In addition, since the reference value can be reset every time the first and second substrates are opened and closed after the power is turned on, a detection state suitable for an environment that changes over time can be obtained. It is possible to effectively detect that an illegal act has been executed.

In the invention according to claim 2,
The summary of the fraud detection means (130) is configured to output the fraud detection signal when the ambient temperature at the position where the fraud detection means (130) is disposed exceeds a reference temperature.
In this way, by outputting a detection signal when the ambient temperature exceeds the reference temperature, it becomes possible to use the fraud detection means in an appropriate temperature environment, effectively preventing false detection by the fraud detection means. it can.

The gist of the invention is that the output of the signal based on the output of the fraud detection signal from the fraud detection means (130) is stopped when the state is detected.
Thus, by outputting a signal based on the output of the fraud detection signal from the fraud detection means in an environment suitable for fraud detection by the fraud detection means with the first and second substrates closed, While the fraudulent act can be accurately managed by the information processing terminal on the amusement store side, etc., the fraud detection means is illegal when the detection environment of the fraud detection means changes with the opening of the first and second substrates. By preventing a signal based on the output of the fraud detection signal from the detection means from being output to the outside, information processing on the amusement shop side assumes that the false detection of the fraud detection means accompanying a change in the detection environment is a fraudulent act. It is possible to prevent processing from being determined by a terminal or the like. For this reason, it becomes possible to grasp | ascertain accurately whether the fraudulent act was performed in the state provided for a game. In addition, when the first and second substrates are closed after the detection environment of the fraud detection unit is changed with the opening of the first and second substrates, the reference value is reset as described above. Thus, it is possible to maintain a state suitable for detecting fraud by the fraud detection means.

In the invention according to claim 4,

A fraud detection signal is output from the fraud detection means (130) in a state where the open / close detection means (112) detects the relative closed state of the first base (11) and the second base (12, 13). In the case where it is determined, the abnormality notification determining means (60a) determines that the abnormality based on the detection by the fraud detection means (130) is notified, and the opening / closing detection means (112) is the first base ( 11) When a fraud detection signal is output from the fraud detection means (130) in a state where the relative open state of the second substrate (12, 13) is detected, the detection by the fraud detection means (130). The summary is that the abnormality notification determining means (60a) determines that the abnormality based on the above is not notified.
In this way, in an environment suitable for detecting fraud by the fraud detection means in which the first and second bases are closed, the abnormality is notified based on the output of the fraud detection signal from the fraud detection means. By deciding, it is possible to promptly notify that an illegal act has been performed. On the other hand, in a state where the detection environment of the fraud detection means has changed with the opening of the first and second bases, it is determined not to notify the abnormality based on the output of the fraud detection signal from the fraud detection means. Thus, it is possible to prevent notification of abnormality due to erroneous detection of the fraud detection means accompanying a change in the detection environment. For this reason, it becomes possible to grasp | ascertain accurately whether the fraudulent act was performed in the state provided for a game. In addition, when the first and second substrates are closed after the detection environment of the fraud detection unit is changed with the opening of the first and second substrates, the reference value is reset as described above. Thus, it is possible to maintain a state suitable for detecting fraud by the fraud detection means.

In addition, the pachinko machine 10 is provided with a power supply board 80 that generates necessary power supply voltages for each part from an external power supply (for example, AC 24 V) of the game arcade and supplies them to various components constituting the pachinko machine 10. . As shown in FIG. 3, the power supply board 80 initializes (clears) a power switch (power switching means) 81 and a main control RAM 60c for switching the pachinko machine 10 between a power-on state (ON) and a power-off state (OFF). A clear switch 82 is provided. Further, the power supply board 80 is provided with a power-off monitoring circuit 83 that is connected to the power switch 81 and outputs a power ON signal and a power OFF signal to the main control board 60 in accordance with ON / OFF switching of the power switch 81. In addition, a clear switch circuit 84 connected to the clear switch 82 is provided. In the embodiment, only when the power switch 81 is turned on while the clear switch 82 is turned on, the clear signal is output from the clear switch circuit 84 to the main control board 60, and the main control board 60 that has received the clear signal. Is set to perform a clear process for initializing the main control RAM 60c.

The clear switch circuit 84 and the clear switch 82 may constitute a clear unit, and a configuration in which a clear signal is output from the clear switch circuit 84 to the main control board 60 when the clear switch 82 is turned on may be employed.

  As shown in FIG. 3, the power supply board 80 has a power supply circuit (power supply means) for converting an external power supply (AC24V) of the game hall into a power supply voltage (for example, DC30V) supplied to various electronic components of the pachinko machine 10. 85 is provided. The power supply circuit 85 is connected to the control boards 60, 65, and 70. The power supply circuit 85 supplies a predetermined power supply voltage corresponding to the control boards 60, 65, and 70 after the conversion process. The power supply voltage is converted into a power supply voltage and the converted power supply voltage is supplied to the corresponding control boards 60, 65, and 70.

  The power supply board 80 is provided with the power supply interruption monitoring circuit 83 connected to the power supply circuit 85. The power supply interruption monitoring circuit 83 may be a power supply voltage supplied to the power supply circuit 85 (hereinafter also referred to as a monitoring power supply voltage). Configured to monitor voltage values). Specifically, the power-off monitoring circuit 83 determines whether or not the monitored power supply voltage has dropped to a predetermined voltage (hereinafter sometimes referred to as a threshold voltage). The threshold voltage is set to a minimum voltage (for example, DC 20 V) necessary for operating the electronic components (for example, the detection sensor) of the pachinko machine 10 without causing any trouble in the game. Here, the monitored power supply voltage drops to the threshold voltage, for example, when the power is turned off (power is turned off) or during a power failure. In this case, since power is not supplied to the pachinko machine 10, the monitoring power supply voltage drops to the threshold voltage. The threshold voltage is set to a value that is higher by a predetermined margin than the voltage at which the electronic component stops operating.

  The power supply board 80 is provided with a reset signal circuit 86 that is connected to the power-off monitoring circuit 83. When the determination result is affirmative (that is, when the monitoring power supply voltage is equal to or lower than the threshold voltage), the power interruption monitoring circuit 83 monitors the power supply for the main control board 60, the overall control board 65, and the reset signal circuit 86. It is configured to output a power-off signal indicating that the voltage has dropped to the threshold voltage. The reset signal circuit 86 outputs a reset signal to the main control board 60, the overall control board 65, and the display control board 70 at the start of power supply (when power is turned on or when power is restored) and when a power-off signal is input. The operation of the main control board 60, the overall control board 65, and the display control board 70 is regulated.

  Specifically, when the power-off signal is input from the power-off monitoring circuit 83, the main control CPU 60a performs main control CPU 60a based on the main control power-off processing program among the control programs stored in the main control RAM 60c. Execute the power-off process. In the main control power-off process, various control information such as various flags and random numbers stored and held in the regular storage area of the main control RAM 60c are stored and held in the main backup area of the main control RAM 60c. Access to the RAM 60c is prohibited, and a setting is made to wait for input of a reset signal from the reset signal circuit 86. Similarly, when the power-off signal is input from the power-off monitoring circuit 83, the overall control CPU 65a receives the overall control power-off processing program out of the control programs stored in the overall control RAM 65c. Execute power-off processing. In the power-off processing for the overall control, various control information such as various flags and game processing information stored and held in the regular storage area of the overall control RAM 65c are stored and held in the main backup area of the overall control RAM 65c. Access to the control RAM 65c is prohibited, and setting is made to wait for input of a reset signal from the reset signal circuit 86. That is, various control information at the timing when the power-off signal is input is stored and retained as backup data, and when the power supply to the pachinko machine 10 is restored (power recovery), the power-off occurs based on the backup data. It is configured to be able to return to the timing state.

  Further, the power supply board 80 is provided with a backup power supply 87 such as a capacitor. When the main power supply of the pachinko machine 10 is turned off and the supply of power is stopped (the power switch 81 is turned off or a power failure is caused by an external power supply). When the power cut-off signal is output from the power cut-off monitoring circuit 83 due to the interruption of the power supply), power is supplied from the backup power supply 87 to the main control CPU 60a and the overall control CPU 65a. The backup power supply 87 is used for the time required for both control CPUs 60a and 65a to store (write) various information stored in the corresponding control RAMs 60c and 65c in the backup areas set in the control RAMs 60c and 65c. Power can be supplied. Further, both the control RAMs 60c and 65c are configured to hold various information stored in the backup area even after the power supply is cut off. Note that the backup area is set separately from the regular storage area used for temporarily storing the various information during operation of the pachinko machine 10, and when the power supply is cut off due to a power failure or the like, This is an area for storing various types of information at the time of power supply interruption in order to restore the state of the pachinko machine 10 to the state at the time of power supply interruption at the start (at power recovery).

(About processing at power-on)
Next, a description will be given of a control process that is performed when the pachinko machine 10 is powered on (power supply is started). When the pachinko machine 10 is turned on, the reset signal circuit 86 continuously outputs reset signals to the main control CPU 60a, the overall control CPU 65a, and the display control CPU 70a until a predetermined regulation time elapses. At this time, the continuous output time of the reset signal to the main control CPU 60a is set to, for example, 1 second so as to be longer than the continuous output time of the reset signal to the overall control CPU 65a and the display control CPU 70a.

(Main control power-on processing)
When the input of the reset signal once inputted stops, the main control CPU 60a executes the main control power-on process based on the main control power-on process program stored in the main control ROM 60b. In this main control power-on process, as shown in FIG. 4A, the main control CPU 60a determines whether or not the clear switch 82 is operated (step 101). When step 101 is affirmative, the main control CPU 60a proceeds to step 103, and erases (varies RAM) various control information stored and held in the main control RAM 60c. Thereafter, the main control CPU 60a sets initial information stored in the main control ROM 60b, and activates the pachinko machine 10 based on the initial information (step 104). Then, the main control CPU 30a outputs an initial information control command indicating that the pachinko machine 10 has been activated based on the initial information to the overall control CPU 31a (step 105). Further, when the process related to the activation of the pachinko machine 10 is completed, a sensor confirmation process (step 106) for confirming whether or not the magnetic detection sensor 130 has been activated normally is executed. When it is confirmed in the sensor confirmation process that the magnetic detection sensor 130 has been normally activated, the main control CPU 60a ends the main control power-on process.

  If step 101 is negative, the main control CPU 60a performs main control return processing (step 102). As shown in FIG. 4B, in the main control return process, the main control CPU 60a performs the same calculation process as the main control power-off process in step 111, based on various control information stored and held in the main control RAM 60c. Calculate the checksum. Then, the main control CPU 60a determines whether or not the checksum calculated in step 111 matches the checksum stored and held in the backup area of the main control RAM 60c (step 112). If the determination result of step 112 is negative, it is determined that the various control information being backed up is abnormal, and the main control CPU 60a proceeds to the process of step 103 in FIG. 4 (a).

  Note that the negative result of the determination at step 112 is that the main control power-off process is not performed normally when the power supply is cut off, or that there is an abnormality in the stored contents due to noise or the like after the main control power-off process. May occur. In such a case, the checksum calculated in step 111 indicates an abnormality (abnormal value).

  On the other hand, if step 112 is affirmative, that is, if the various control information backed up is correct, the main control CPU 60a sets the pachinko machine 10 based on the various control information stored in the main backup area of the main control RAM 60c. Start (step 113). The main control CPU 60a outputs a power recovery control command for designating control information stored and managed in the main control RAM 60c to the overall control CPU 65a (step 114). Further, when the process related to the activation of the pachinko machine 10 is completed, a sensor confirmation process (step 115) for confirming whether or not the magnetic detection sensor 130 has been activated normally is executed. When it is confirmed in the sensor confirmation process that the magnetic detection sensor 130 has been normally activated, the main control CPU 60a finishes the main control return process and returns to the state before the power supply is shut off.

(About processing related to magnetic sensor)
Next, processing related to the magnetic detection sensor 130 will be described. As described above, the processing circuit unit 132 of the magnetic detection sensor 130 provided in the pachinko machine 10 according to the embodiment is used when the fluctuation range of the detection value of the sensor unit 131 due to the change in the external magnetic field exceeds a predetermined detection threshold. When the fluctuation range of the detection value detected by the sensor unit 131 does not exceed a predetermined detection threshold value from the magnetic detection reference value, the processing circuit unit 132 determines that the magnetic detection state is not detected and determines the magnetic detection state. Alternatively, a magnetic non-detection signal is output. Here, even in a normal environment where the magnet is not improperly approached, the operation of the symbol display device 17 installed in the pachinko machine 10, the operation of various rendering devices having drive means such as a solenoid or a motor, pachinko Since the detection value detected by the sensor unit 131 varies depending on the environment of each amusement store where the machine 10 is installed, these influences cannot be ignored for accurate magnetic detection. Therefore, in the embodiment, the magnetic detection sensor 130 (processing circuit unit 132) sets the magnetic detection reference value according to the surrounding environment, and the detection value of the sensor unit 131 exceeds the detection threshold with respect to the magnetic detection reference value. If it fluctuates, the magnetic detection state is determined. That is, the processing circuit unit 132 of the magnetic detection sensor 130 functions as a setting unit that sets a magnetic detection reference value (reference value) that serves as a reference for the fraud detection unit to output a fraud detection signal.

(Initial value setting process)
When power is supplied to the magnetic detection sensor 130, an initial value setting process for setting an initial value according to the environment in which the magnetic detection sensor 130 is installed is performed. In this initial value setting process, the magnetic detection reference value serving as a reference for the magnetic detection sensor 130 (specifically, the processing circuit unit 132) to output a magnetic detection signal is set according to the surrounding environment at the time when the power is supplied. It is processing to do. Specifically, the detection value that the magnetism detection sensor 130 (sensor unit 131) detects magnetism with the supply of power is set to be smaller than the magnitude of the earth's magnetic field (that is, the magnitude of the earth's magnetic field> the detected value). Thus, the magnetic detection sensor 130 always detects the magnetic field. In this state, the detection values of a predetermined sampling number N (N is a natural number) detected by the magnetic detection sensor 130 (sensor unit 131) are integrated, and the integrated value is divided by the sampling number N to obtain the magnetic detection reference value. Configured to set. This magnetic detection reference value is stored in the sensor storage unit 134 provided in the magnetic detection sensor 130.

  In addition, the magnetic detection sensor 130 (specifically, the processing circuit unit 132) sets an initial value for the main control CPU 60a when the maximum and minimum values of magnetic detection detected in the initial value setting process exceed a predetermined value. It is configured to output a value setting error signal. That is, when an excessive fluctuation occurs in the detection value detected by the magnetic detection sensor 130 in the initial value setting process, a magnet or the like may exist around the sensor 130, and magnetism can be detected normally. Since the magnetic detection reference value may not be set in the value, the main control CPU 60a can recognize that the initial value setting process is not normally completed by outputting an initial value setting error signal. The width between the maximum value and the minimum value of magnetic detection that triggers the magnetic detection sensor 130 to output an initial value setting error signal can be set arbitrarily, but if it is too small, illegal magnetism is used. Even if a normal magnetic field variation that may occur in an environment where no illegal acts are performed, the initial value setting is not normally completed, and if the width is too large, the magnetic detection sensor 130 may detect an irregular magnetic field variation. It cannot be detected. Therefore, for example, the fluctuation range of the detection value of the magnetic detection sensor 130 detected when a standard magnet having a surface magnetic flux of 430 mT arranged at a distance of 10 cm from the magnetic detection sensor 130 is moved in a direction away from the sensor 130 by 15 cm. It is preferable to use a determination value as to whether or not to output an initial value setting error signal. Further, when the maximum value of the magnetic detection detected in the initial value setting process exceeds a predetermined value, an initial value setting error signal is output to the main control CPU 60a.

  When the initial value setting process is normally completed (the setting of the magnetic detection reference value is completed), the magnetic detection sensor 130 (specifically, the processing circuit unit 132) outputs an initial value setting completion signal to the main control CPU 60a. As the initial value setting completion signal is input, the main control CPU 60a sets “1” as the initial value setting completion flag in the flag setting area of the main control RAM 60c. That is, the main control CPU 60a is configured to identify that the initial value setting process has been normally completed by referring to the initial value setting completion flag in the main control RAM 60c.

  In addition, when the initial value setting process is improperly completed (when the initial value setting error signal is output), the magnetic detection sensor 130 (specifically, the processing circuit unit 132) controls the initial value setting error signal as the main control. As the initial value setting error signal is input to the CPU 60a, the main control CPU 60a sets "1" as the initial value setting error flag in the flag setting area of the main control RAM 60c. That is, by referring to the initial value setting error flag in the main control RAM 60c, the main control CPU 60a can identify that an abnormality has occurred in the initial value setting process. When the initial value setting process is not normally completed, the main control CPU 60a performs an error notification process in the sensor confirmation process. That is, when the initial value setting process is illegally completed, an initial value setting error signal is output from the main control CPU 60a to the overall control CPU 65a, indicating that an abnormality has occurred in the initial value setting of the magnetic detection sensor 130. The information to be notified is displayed on the symbol display device 17 and at the same time, it is notified that an abnormality has occurred in the initial value setting by the light emission of the lamp device 105 and the sound effect output from the speaker 106. Further, the main control CPU 60a is configured to transmit an initial value setting error signal to the hall computer HC, and can notify that an abnormality has occurred in the initial value setting of the magnetic detection sensor 130 through the hall computer HC. ing. That is, the main control CPU 60a has a function as an abnormality notification determination unit that determines whether or not to notify an abnormality based on a detection signal from the magnetic detection sensor 130 as an unauthorized detection unit. In the embodiment, the main control CPU 60a determines whether or not to notify the abnormality based on any of the initial value setting error signal, the reset error signal, and the magnetic detection signal that can be output from the magnetic detection sensor 130. It has become.

(Reference value correction processing)
The pachinko machine 10 according to the embodiment is configured to perform a reference value correction process for correcting (resetting) the magnetic detection reference value of the magnetic detection sensor 130 at an appropriate timing after the initial value setting process is performed. Yes. That is, by correcting (resetting) the magnetic detection reference value once set with the power supply, the magnetic detection reference value is adapted to the magnetic field environment that changes over time, and the magnetic detection accuracy by the magnetic detection sensor 130 is maintained. It is configured to be able to. In the embodiment, the processing circuit unit 132 corrects the magnetic detection reference value of the magnetic detection sensor 130 when the open detection sensor 112 detects the relative closed state of the frames 11, 12, and 13 after the power is supplied. It is configured to (reset). Further, the processing circuit unit 132 of the magnetic detection sensor 130 every time the open detection sensor 112 detects that the frames 11, 12, and 13 are changed from the relative open state to the closed state in a state where power is supplied. The magnetic detection reference value of the magnetic detection sensor 130 is corrected (reset).

  Specifically, as shown in FIG. 5, in the reference value correction process, the main control CPU 60a determines whether or not the initial value setting process of the magnetic detection sensor 130 has been normally completed (step 201). When the initial value setting process is not normally completed, the reference value correction process is terminated without resetting the magnetic detection reference value. That is, when the magnetic detection sensor 130 outputs the magnetic detection signal as the initial value setting error signal because the initial value setting is not normally completed, the initial value of the magnetic detection reference value is not normally set. The magnetic detection reference value is not reset. Here, the determination as to whether or not the initial value setting process has been normally completed is determined by the initial value setting completion flag set in the main control RAM 60c based on the signal output from the magnetic detection sensor 130 in the initial value setting process. This can be executed by determining whether or not the value is a value indicating normal completion (“1” in the embodiment).

  Further, when the initial value setting process in the magnetic detection sensor 130 has been normally completed, the main control CPU 60a determines whether or not the first reference value correction process has been completed since the initial setting (step S1). 202). If the first reference value correction process is not completed, whether or not each of the frames 11, 12, 13 is in a relative closed state (that is, whether the open detection sensor 112 has detected a closed state). ) Is determined by the main control CPU 60a (step 203), and the sensor correction signal is output to the magnetic detection sensor 130 when the open detection sensor 112 detects the closed state (when the input signal is a close signal). Is output (step 204). As described above, when the initial value setting process is normally completed and the frames 11, 12, and 13 are relatively closed to each other and the open detection sensor 112 detects the closed state, the main control CPU 60a detects the magnetic detection. A sensor correction signal is output to the sensor 130, and the magnetic detection sensor 130 resets the magnetic detection reference value. When the open detection sensor 112 does not detect the closed state (when the input signal is an open signal), the apparatus waits until the frames 11, 12, and 13 are in the closed state.

  By the way, the situation where the power is turned on to the pachinko machine 10 includes a case where a plurality of pachinko machines 10 are turned on simultaneously or individually by a control signal from a hall computer installed at the game shop side, It is generally assumed that the operator operates the power switch 81 provided on the power supply board 80 by opening the frame 12 with respect to the outer frame 11 to turn on the power for each pachinko machine 10. Here, in the case of operating the power switch 81 of the power board 80, the middle frame 12 is opened to operate the power switch 81 when the power is turned on, and the middle frame 12 is closed after the work is completed. There is a concern that the magnetic field environment of the magnetic detection sensor 130 changes between when the game is performed and when the game is performed, which affects the magnetic detection accuracy of the magnetic detection sensor 130. Therefore, the magnetic detection sensor 130 resets the magnetic detection reference value at the timing when the frames 11, 12, and 13 are closed after the initial value setting process of the magnetic detection sensor 130 is completed, so that the magnetism by the magnetic detection sensor 130 is set. Increases detection accuracy. In addition, by executing the initial value setting process, it is possible to quickly determine whether or not there is an abnormality in the surrounding environment of the magnetic detection sensor 130.

  Further, when the first reference value correction process is completed, the main control CPU 60a determines whether or not each of the frames 11, 12, 13 has changed from the open state to the closed state (step 205). When the state is changed from the open state to the closed state, a sensor correction signal is output to the magnetic detection sensor 130 to cause the magnetic detection sensor 130 to reset the magnetic detection reference value. On the other hand, when the frames 11, 12, and 13 are not changed from the open state to the closed state (that is, when the frames 11, 12, and 13 are maintained in the closed state), the magnetic detection sensor 130 is Thus, the reference value correction process is terminated without outputting the sensor correction signal, and the magnetic detection reference value is not reset by the magnetic detection sensor 130.

  Here, a reference value resetting process in which the magnetic detection sensor 130 corrects (resets) the magnetic detection reference value will be described. When a sensor correction signal is input from the main control CPU 60a, the magnetic detection sensor 130 resets the magnetic detection reference value according to the magnetic field environment at the timing when the sensor correction signal is input. This reference value resetting process is basically the same as the initial value setting process described above. Specifically, the detection value that the magnetism detection sensor 130 detects magnetism with the input of the sensor correction signal is set to be smaller than the magnitude of the earth's magnetic field (that is, the magnitude of the earth's magnetic field> the detected value) The magnetic detection sensor 130 always detects the magnetic field. In this state, the detection values of a predetermined sampling number N (N is a natural number) detected by the magnetic detection sensor 130 (sensor unit 131) are integrated, and the integrated value is divided by the sampling number N to obtain the magnetic detection reference value. Configured to set.

  Further, the magnetic detection sensor 130 outputs a reset error signal to the main control CPU 60a when the width between the maximum value and the minimum value of the magnetic detection detected in the reference value reset process exceeds a predetermined value. It is configured. That is, when an excessive variation occurs in the detection value detected by the magnetic detection sensor 130 in the reference value resetting process, a magnet or the like may exist around the sensor 130, and the magnetism is detected normally. Since there is a possibility that the magnetic detection reference value may not be set to the obtained value, the main control CPU 60a can recognize that the reference value resetting process has not been normally completed by outputting a reset error signal. . The width between the maximum value and the minimum value of the magnetic detection that triggers the magnetic detection sensor 130 to output the reset error signal can be arbitrarily set. However, if it is too small, it may be caused by fluctuations in the normal magnetic field. If the initial value setting is not normally completed and the width is too large, the magnetic detection sensor 130 cannot detect even if an incorrect magnetic field fluctuation occurs. Therefore, for example, the fluctuation range of the detection value of the magnetic detection sensor 130 detected when a standard magnet having a surface magnetic flux of 430 mT arranged at a distance of 10 cm from the magnetic detection sensor 130 is moved in a direction away from the sensor 130 by 15 cm, It is preferable to use a determination value as to whether or not to output a reset error signal. Further, when the maximum value of magnetic detection detected in the reference value resetting process exceeds a predetermined value, a reset error signal is output to the main control CPU 60a. Note that the determination value for determining whether or not to output a reset error signal in the reference value resetting process may be different from the determination value for determining whether or not to output an initial value setting error signal in the above-described initial value setting process. Good.

  When the reference value resetting process is normally completed (resetting of the magnetic detection reference value is completed), the magnetic detection sensor 130 outputs a reset completion signal to the main control CPU 60a, and the reset completion signal is With the input, the main control CPU 60a sets “1” as a reset completion flag in the flag setting area of the main control RAM 60c. That is, it is possible to identify that the magnetic detection reference value has been reset by referring to the reset completion flag in the main control RAM 60c.

  In addition, when the reference value resetting process is always completed illegally (when a reset error signal is output), the magnetic detection sensor 130 outputs a reset error signal to the main control CPU 60a, and the reset error signal Is input, the main control CPU 60a sets “1” as the reset error flag in the flag setting area of the main control RAM 60c. That is, by referring to the reset error flag in the main control RAM 60c, the main control CPU 60a can identify that an abnormality has occurred in the reference value reset processing. Here, the main control CPU 60a is configured to execute the sensor confirmation process at an appropriate timing after the reference value correction process. When the reference value resetting process has not been completed normally, the main control CPU 60a performs the sensor confirmation process. The main control CPU 60a performs an error notification process. Thus, the sensor confirmation process is configured to be executed not only when the power to the pachinko machine 10 is turned on, but also at a timing after the process in which the magnetic detection sensor 130 sets or resets the magnetic detection reference value. That is, when the reference value resetting process is always completed illegally, a reset error signal is output from the main control CPU 60a to the overall control CPU 65a to notify that an abnormality has occurred in resetting the magnetic detection sensor 130. The contents to be displayed are displayed on the symbol display device 17, and notification is made that an abnormality has occurred in the resetting by the light emission of the lamp device 105 and the sound effect output from the speaker 106. Further, the main control CPU 60a is configured to transmit a reset error signal to the hall computer HC, and can notify that an abnormality has occurred in the reset of the magnetic detection sensor 130 through the hall computer HC. .

(Sensor-side magnetism detection processing)
Next, the sensor-side magnetic detection process performed by the magnetic detection sensor 130 will be described. As shown in FIG. 6, when the initial value setting process and the first sensor correction signal described above are completed after the power to the pachinko machine 10 is turned on, the magnetic detection sensor 130 enters a standby state in which magnetic detection is possible. The processing circuit unit determines whether or not the fluctuation range of the detected value detected exceeds a predetermined detection threshold (that is, whether or not illegal magnetism is detected) every predetermined period (for example, every 20 milliseconds). This is repeated at 132 (step 301). When the fluctuation range of the detection value detected by the sensor unit 131 exceeds a predetermined detection threshold, it is determined whether or not the frames 11, 12, and 13 are relatively closed with respect to each other. The determination is made by the (processing circuit unit 132) (step 302).

  Here, in the pachinko machine 10 of the embodiment, when a closing signal indicating that the frames 11, 12, 13 are relatively closed to each other is input from the opening detection sensor 112 to the main control CPU 60 a, The main control CPU 60a outputs a closing signal to the magnetic detection sensor 130, and an opening signal indicating that one of the frames 11, 12, 13 is relatively opened is sent from the opening detection sensor 112 to the main control CPU 60a. The main control CPU 60a is configured to output an open signal to the magnetic detection sensor 130. When a closing signal is input from the main control CPU 60a to the magnetic detection sensor 130, a closing flag indicating a closed state is set in the flag setting area of the sensor storage unit 134 included in the magnetic detection sensor 130, and When an open signal is input from the control CPU 60a to the magnetic detection sensor 130, an open flag indicating an open state is set in the flag setting area of the sensor storage unit 134 provided in the magnetic detection sensor 130. That is, in the magnetic detection sensor 130 of the embodiment, the processing circuit unit 132 sets the flag stored in the sensor storage unit 134 when the fluctuation range of the detection value detected by the sensor unit 131 exceeds a predetermined detection threshold. Referring to this, it is determined whether or not the frames 11, 12, and 13 are closed relative to each other.

  The magnetic detection sensor 130 outputs a magnetic detection signal to the main control CPU 60a when the frames 11, 12, 13 are relatively closed to each other (step 303), and the main control CPU 60a On the other hand, it is configured to notify that an illegal magnetism is detected. On the other hand, the magnetic detection sensor 130 prevents the magnetic detection sensor 130 from outputting a magnetic detection signal to the main control CPU 60a when any of the frames 11, 12, 13 is relatively opened. It is configured. Thus, in the embodiment, in a situation where the open detection sensor 112 detects a state in which one of the frames 11, 12, 13 is relatively open, the magnetic detection sensor 130 stops outputting the magnetic detection signal. It is configured. That is, when the middle frame 12 and the front frame 13 are released due to a clogged ball on the game board 20 that may occur in the process of playing a game in the pachinko machine 10 or a malfunction of the pachinko ball, etc., the magnetic detection sensor 130 is opened. Since the output of the magnetic detection signal is stopped, the processing of the main control CPU 60a performed in accordance with the input of the magnetic detection signal can be omitted. At this time, since the opening signal is input from the opening detection sensor 112 to the main control CPU 60a, the main control CPU 60a can appropriately perform the process associated with the opening of the middle frame 12 and the front frame 13.

  In addition, the magnetic detection sensor 130 of the embodiment is configured such that the detection value output from the sensor unit 131 changes according to the temperature around the magnetic detection sensor 130. Specifically, the sensor unit 131 of the magnetic detection sensor 130 is configured so that the detection value increases when the temperature rises, and the ambient temperature at the position where the magnetic detection sensor 130 is disposed is the reference temperature (for example, 60 ° C.). Is configured to output a magnetic detection signal when the value exceeds. As described above, when the ambient temperature exceeds the reference temperature, the magnetic detection sensor 130 outputs a magnetic detection signal, so that the magnetic detection sensor 130 can be used in an appropriate temperature environment. An erroneous detection of the detection sensor 130 can be effectively prevented.

(Main side magnetism detection processing)
Next, a main-side magnetism detection process performed by the main control CPU 60a when the magnetism detection sensor 130 detects magnetism will be described. As shown in FIG. 7, when the start-up of the pachinko machine 10 is completed, the main control CPU 60a determines whether or not a magnetic detection signal is input from the magnetic detection sensor 130 at a predetermined cycle (for example, every 20 milliseconds). Repeatedly (step 401). When a magnetic detection signal is input from the magnetic detection sensor 130, the main control CPU 60a determines whether or not the frames 11, 12, 13 are relatively closed to each other (step 402). In the embodiment, referring to the open / close state flag stored in the flag setting area of the main control RAM 60c in response to the input of the close signal and the open signal from the open detection sensor 112, the frames 11, 12, 13 are mutually connected. The main control CPU 60a determines whether or not it is relatively closed. That is, when the open / close state flag stored in the flag setting area of the main control RAM 60c is “0”, the main control CPU 60a determines that the frames 11, 12, and 13 are relatively closed. When the open / close state flag is “1”, the main control CPU 60a determines that one of the frames 11, 12, 13 is relatively open.

  When the magnetism detection sensor 130 detects magnetism in a state where the frames 11, 12, and 13 are closed relative to each other, the main control CPU 60a performs a process of performing an abnormality notification based on the magnetism detection. (Steps 403 and 404). Specifically, the main control CPU 60 a outputs a magnetic abnormality detection signal to the general control board 65 (general control CPU 65 a), and the general control CPU 65 a that receives the magnetic abnormality detection signal outputs a magnetic abnormality to the display control board 70. An anomaly detection signal is output to display on the symbol display device 17 the content for notifying that anomalous magnetism has been detected. The magnetic abnormality detection signal is output from the overall control CPU 65a to the lamp control board 72, the sound control device 73 and the like, and when the game is performed on the lamp device 105 provided in the front frame 13. It is configured to notify that abnormal magnetism has been detected by causing the speaker 106 to output a sound effect or the like that is different from the light emission mode when the game is performed, or to emit light in a mode different from the light emission mode. Yes. As described above, in the pachinko machine 10 according to the embodiment, when the magnetic detection sensor 130 detects magnetism in a state where the frames 11, 12, and 13 are relatively closed to each other, the display or lamp of the symbol display device 17 is displayed. The operator of the amusement shop can recognize that abnormal magnetism has been detected by the light emission of the device 105, the sound effect from the speaker 106, and the like. That is, the main control CPU 60a has a function as an abnormality notification determination unit that determines whether or not to notify an abnormality based on a magnetic detection signal from the magnetic detection sensor 130.

  In the pachinko machine 10 according to the embodiment, the operation lever 16a of the operation handle 16 is operated when the magnetic detection sensor 130 detects magnetism in a state where the frames 11, 12, and 13 are relatively closed to each other. Regardless of whether or not it is performed, the main control CPU 60a is configured to control the operation of the ball striking device 18 to stop. That is, by forcibly stopping the operation of the hitting ball launching device 18, it is possible to prevent the game from being continued in a situation where abnormal magnetism is detected. That is, the main control CPU 60a has a function as an operation stop determining unit that determines whether to stop the operation of the pachinko machine 10 based on the magnetic detection signal from the magnetic detection sensor 130.

  In addition, the pachinko machine 10 of the embodiment is electrically connected to a computer (hall computer) provided in the game store via an external terminal portion (see FIG. 3) provided on the back side of the middle frame 12. When the magnetic detection sensor 130 detects magnetism with the frames 11, 12, 13 being closed relative to each other, the main control CPU 60a sends a magnetic abnormality detection signal to the hall computer via the external terminal plate. It is configured to send. As described above, by transmitting the magnetic abnormality detection signal to the hall computer, abnormal magnetism is detected separately from the notification by the symbol display device 17, the lamp device 105, the speaker 106, and the like individually performed by the pachinko machine 10. The game store can recognize this and encourage appropriate responses.

  Further, as shown in FIG. 7, when any of the frames 11, 12, 13 is relatively opened, the main control CPU 60a performs a process of performing an abnormality notification based on the detection of the frame opening. (Steps 405 and 406). That is, when a magnetic detection signal is input from the magnetic detection sensor 130 in a state where the open detection sensor 112 detects the relative open state of the frames 11, 12, and 13, the detection of the magnetic detection sensor 130 is performed. The main control CPU 60a decides not to report the abnormality based on it. On the other hand, in this case, the main control CPU 60a determines to perform abnormality notification based on the opening detection by the opening detection sensor 112. Specifically, the main control CPU 60a outputs a frame open detection signal to the general control board 65 (general control CPU 65a), and the general control CPU 65a receiving the frame open detection signal outputs a frame open detection signal to the display control board 70. An opening detection signal is output to display on the symbol display device 17 the contents for notifying that any of the frames 11, 12, 13 is open. The frame opening detection signal is output from the overall control CPU 65a to the lamp control board 72, the sound control device 73, and the like, and when the game is performed on the lamp device 105 provided in the front frame 13. Any of the frames 11, 12, and 13 can be opened by causing the speaker 106 to output a sound effect or the like that is different from the light emission mode when the game is performed, or to emit light in a mode different from the light emission mode. It is comprised so that it may alert | report.

  In addition, when the magnetism detection sensor 130 detects magnetism in a state where any of the frames 11, 12, 13 is relatively opened, the main control CPU 60 a sends a frame open detection signal via the external terminal plate. It is configured to send to a computer. At this time, the main control CPU 60a does not transmit a magnetic detection signal based on the abnormality detection of the magnetic detection sensor 130 to the hall computer via the external terminal board. That is, when a magnetic detection signal is input from the magnetic detection sensor 130 in a state where the open detection sensor 112 detects the relative open state of the frames 11, 12, and 13, the detection of the magnetic detection sensor 130 is performed. The main control CPU 60a determines to stop outputting the signal based on the outside. On the other hand, in this case, the main control CPU 60a determines that a signal based on the opening detection by the opening detection sensor 112 is output to the outside. As described above, by transmitting the frame opening detection signal to the hall computer, abnormal magnetism is detected separately from the notification by the symbol display device 17, the lamp device 105, the speaker 106, and the like individually performed by the pachinko machine 10. The game store can recognize this and encourage appropriate responses.

  Further, the main control CPU 60a of the embodiment is configured such that, when the magnetism detection sensor 130 detects magnetism, a plurality of (two in the embodiment) magnetism detection sensors 130 provided so that the magnetism detection regions R overlap with each other simultaneously. The main control CPU 60a is configured to determine whether or not it is detected. When a part of a plurality of (two in the embodiment) magnetic detection sensors 130 provided to overlap the magnetic detection regions R detect magnetism, the magnetic detection by some of the magnetic detection sensors 130 is performed. The main control CPU 60a is configured to determine that the abnormality of the magnetic detection sensor 130 is abnormal when the magnetic detection by the part of the magnetic detection sensors 130 continues beyond a predetermined reference number. As described above, in the embodiment, in the multiple areas where the magnetic detection areas R of the plurality of magnetic detection sensors 130 overlap, the structure that is likely to be a target of fraud using magnetism is arranged, and magnetism is used. When an illegal act is performed, the plurality of magnetic detection sensors 130 are configured to increase the possibility of detecting magnetism at a time so that the magnetic detection regions R overlap. That is, when the state in which only a part of the plurality of magnetic detection sensors 130 provided so that the magnetic detection regions R overlap is detecting the magnetism continues, There is a possibility that the magnetic detection sensor 130 has been illegally modified. Therefore, when the magnetic detection by some of the magnetic detection sensors 130 continues beyond a predetermined reference number, the main control CPU 60a determines that the magnetic detection sensor 130 is abnormal, thereby prompting the inspection of the magnetic detection sensor 130, etc. It is like that.

  In the embodiment, when the magnetic detection by some of the magnetic detection sensors 130 continues for a predetermined reference number of times, a sensor confirmation signal is output from the main control CPU 60a to the overall control board 65 (overall control CPU 65a). At the same time, the overall control CPU 65a that has received the sensor confirmation signal outputs a sensor confirmation signal to the display control board 70 to display on the symbol display device 17 the content for notifying that the magnetic detection sensor 130 should be confirmed. It has become. Further, the main control CPU 60a is configured to transmit a sensor confirmation signal to the hall computer via the external terminal board. In this way, by sending the sensor confirmation signal to the hall computer, the game store is made aware that the magnetic detection sensor 130 should be inspected separately from the notification by the symbol display device 17 that is individually performed in the pachinko machine 10. , Can encourage an appropriate response.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the embodiment configured as described above will be described.

  In the pachinko machine 10 of the embodiment, when the power is turned on by operating the power switch 81 provided on the power board 80, the main control CPU 60a executes the main control power-on process, and the initial setting state of the pachinko machine 10 is achieved. Alternatively, the state before the interruption of power supply is restored. In addition, when the power is turned on, an initial value setting process is executed in the magnetic detection sensor 130, and the magnetic detection reference value serving as a reference for the magnetic detection sensor 130 to output a magnetic detection signal to the main control CPU 60a is set. . If the magnetic detection reference value is not normally set in the initial value setting process, an initial value setting error signal is output from the magnetic detection sensor 130 to the main control CPU 60a, and the main control is performed based on the initial value setting error signal. Since the CPU 60a performs the error notification process, the game store can be prompted to remove the magnet that caused the error, and the magnetic detection reference value is not normally set for the magnetic detection sensor 130. It can be prevented from being used in games.

  In addition, when the magnetic detection reference value is normally set in the initial value setting process, the opening detection sensor 112 detects the relative closed state of each of the frames 11, 12, 13, and the pachinko machine 10 is used for the game. In this state, the magnetic detection reference value set in the initial value setting process is corrected (reset). That is, when the operator operates the power switch 81 provided on the power supply board 80 with the middle frame 12 opened from the outer frame 11 to turn on the power, the middle frame is set at the timing when the initial value setting process is performed. 12 is open to the outer frame 11, and there is a concern that the magnetic detection reference value is set in an environment different from the magnetic field environment in which the pachinko machine 10 is actually used for games. In other words, when the pachinko machine 10 is turned on, the magnetic detection reference value at which the magnetic detection sensor 130 outputs a magnetic detection signal when the frames 11, 12, and 13 are closed. By resetting, it is possible to achieve an appropriate magnetic detection accuracy that matches the installation environment of the pachinko machine 10.

  In addition, when the power is turned on, activation of the symbol display device 17 included in the pachinko machine 10, operation confirmation of the movable effect device, etc., and other initial setting operations are performed at one time. The magnetic detection sensor 130 resets the magnetic detection reference value for outputting the magnetic detection signal when the frames 11, 12, and 13 are in the closed state. The influence of the initial setting operation on the magnetic detection sensor 130 can be reduced as much as possible. For this reason, it is not limited to the case where the operator operates the power switch 81 provided on the power supply board 80 to turn on the power, but the plurality of pachinko machines 10 are controlled by a control signal from a hall computer installed on the amusement shop side. Even if the power is turned on all at once, after setting the magnetic detection reference value in the period setting process, the magnetic detection reference value is corrected (reset) so that the pachinko machine 10 can be used for games. Therefore, the magnetic detection accuracy can be more suitable.

  Further, in the pachinko machine 10 of the embodiment, the magnetic detection sensor 130 sends a magnetic detection signal to the main control CPU 60a as the frames 11, 12, and 13 are closed after the initial value setting process. Even when the magnetic detection reference value serving as a reference for outputting the image is reset, the magnetic detection reference value is corrected when either the middle frame 12 or the front frame 13 is opened / closed with respect to the outer frame 11. (Reset). Here, in an environment in which a plurality of pachinko machines 10 are installed in parallel at a game store, the operation status of adjacent pachinko machines 10, the status of sound in the game store, the number of players traveling in the game store, or Due to various factors such as the environment outside the amusement store, the magnetic field environment around the magnetic detection sensor 130 changes sequentially from the time the power is turned on even during business hours of the amusement store. For this reason, if the magnetic detection reference value set at the time of power-on is detected as unchanged, the magnetic field cannot be changed, and incorrect magnetism is overlooked, or normal magnetism is detected as illegal magnetism. This may cause a false detection such as On the other hand, in the embodiment, the magnetic detection reference value can be corrected (reset) each time the frames 11, 12, and 13 are opened and closed after the power is turned on. It is possible to achieve a detection state suitable for the magnetic field environment in which it is possible to effectively detect that an illegal act has been executed.

  The magnetic detection sensor 130 of the embodiment is configured such that the detection value output from the sensor unit 131 changes according to the ambient temperature, and outputs a magnetic detection signal when the ambient temperature exceeds the reference temperature. Thus, the magnetic detection sensor 130 can be used in an appropriate temperature environment, and erroneous detection of the magnetic detection sensor 130 can be effectively prevented. Further, as described above, the magnetic detection sensor 130 detects the magnetism when the frames 11, 12, and 13 are opened and closed, and corrects (resets) the magnetic detection reference value, so that the position of the magnetic detection sensor 130 can be changed. The magnetic detection reference value suitable for the ambient temperature can be corrected.

  Further, in the closed state where each frame 11, 12, 13 is closed (that is, an environment suitable for detecting illegal magnetism by the magnetic detection sensor 130), the magnetic detection signal is sent to the main control CPU 60a along with the magnetic detection of the magnetic detection sensor 130. When input, a signal based on the output of the magnetic detection signal (magnetic abnormality detection signal) is configured to be output to the outside via the external terminal unit 95, so that the amusement store indicates that an illegal act has been performed. It can be managed accurately by the information processing terminal (hall computer HC) on the side. On the other hand, when one of the frames 11, 12, 13 is opened and the magnetic detection environment by the magnetic detection sensor 130 is changed, the main control CPU 60 a is based on the output of the magnetic detection signal from the magnetic detection sensor 130. Since the signal is not output from the external terminal unit 95 to the outside, the erroneous detection of the magnetic detection sensor 130 due to the change in the detection environment is processed by the information processing terminal or the like on the amusement store side as an illegal act. Can be prevented. Therefore, it is possible to accurately grasp whether or not an illegal act using illegal magnetism has been performed in a state where the game is used.

  At this time, in a state where any one of the frames 11, 12, 13 is opened, a signal based on the detection signal of the open detection sensor 112 (frame open detection signal) is output to the outside via the external terminal unit 95. Since it is configured, it is possible to accurately manage the opening of the frame with an information processing terminal (hall computer HC) or the like on the amusement store side and appropriately take measures. Even when the magnetism detection sensor 130 detects magnetism, a signal output to the information processing terminal on the amusement store side depends on whether each of the frames 11, 12, 13 is in a closed state or an open state. By changing, it is possible to distinguish and grasp and manage the occurrence of these events (magnetic detection and frame opening), and to grasp the events that should be prioritized. Then, after the detection environment of the magnetic detection sensor 130 changes as the frames 11, 12, 1 are opened, the frames 11, 12, 13 are closed, so that the magnetic detection reference value is restored as described above. Therefore, a state suitable for detecting illegal magnetism by the magnetic detection sensor 130 can be maintained.

  Further, in the closed state where each frame 11, 12, 13 is closed (that is, an environment suitable for detecting illegal magnetism by the magnetic detection sensor 130), the magnetic detection signal is sent to the main control CPU 60a along with the magnetic detection of the magnetic detection sensor 130. When input, a magnetic abnormality detection signal is output from the main control CPU 60a to the sub control board (general control board 65) so that abnormality notification based on the output of the magnetic detection signal is performed. It is possible to promptly notify that it has been detected (that there is a possibility that fraud has been performed). On the other hand, when any of the frames 11, 12, 13 is opened and the magnetic detection environment of the magnetic detection sensor 130 is changed, the magnetic detection signal is sent to the main control CPU 60a along with the magnetic detection of the magnetic detection sensor 130. Since the main control CPU 60a determines that the abnormality notification based on the magnetic detection signal is not performed when it is input, the abnormality notification due to the erroneous detection of the magnetic detection sensor 130 due to the change of the detection environment. Can be prevented. Therefore, it is possible to accurately grasp whether or not an illegal act using illegal magnetism has been performed in a state where the game is used.

  At this time, in a state where any of the frames 11, 12, 13 is opened, the main control CPU 60 a sends a frame to the sub control board (general control board 65) so that notification based on the detection signal of the open detection sensor 112 is performed. Since the opening detection signal is output, it is possible to promptly notify the opening of the frame and prompt an appropriate treatment in accordance with the opening of the frame. Even when the magnetism detection sensor 130 detects magnetism, depending on whether each of the frames 11, 12, 13 is in the closed state or in the open state, the notified content (display content on the symbol display device 17 or By changing the light emission mode of the lamp device 105 and the sound effect from the speaker 106, it is possible to distinguish and grasp and manage the occurrence of these events (magnetic detection and frame opening), and to grasp the event to be prioritized. Can do. Then, after the detection environment of the magnetic detection sensor 130 changes as the frames 11, 12, 13 are opened, the frames 11, 12, 13 are closed, so that the magnetic detection reference value is restored as described above. Therefore, a state suitable for detecting illegal magnetism by the magnetic detection sensor 130 can be maintained.
