The random number initial value counter CINI is a loop counter similar to the big hit random number counter C1 (value = 0 to 676). The jackpot random number counter C1 is periodically updated and stored in the reserved ball storage area 213b of the RAM 213 at the timing when the game ball enters the operation port 55.

  The jackpot type counter C2 is incremented by 1 in order within a range of 0 to 49, and reaches a maximum value (ie, 49) and then returns to 0. In the present embodiment, the jackpot type counter C2 determines whether the probability change state or the normal state is set after the jackpot is finished. The jackpot type counter C2 is periodically updated and stored in the reserved ball storage area 213b of the RAM 213 at the timing when the game ball enters the operation port 55.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. The reach random number counter C3 is periodically updated and stored in the reserved ball storage area 213b of the RAM 213 at the timing when the game ball enters the operation port 55.

  For example, the variation type counter CS is incremented one by one within a range of 0 to 240, for example, and reaches a maximum value (that is, 240) and then returns to 0. The switching display time as a period for switching the color displayed on the first specific lamp unit 63 is determined by the variation type counter CS. This switching display time corresponds to the symbol variation display time of the symbol display device 61. The variation type counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the variation type counter CS is acquired at the time of starting the switching of the color displayed on the first specific lamp unit 63 and determining the variation pattern at the time of starting the variation of the symbol by the symbol display device 61.

  At the start of one game round, the MPU 211 of the main control board 201 uses the values of the counters C1 to C3 and CS stored in the reserved ball storage area 213b to perform a big hit lottery or the first specific lamp unit 63. The switching time of the color displayed on the screen is determined, but the information on the lottery result and the switching time determined here are transmitted to the sound lamp control device 113 as a game turn command. The sound lamp control device 113 determines the effect contents of the corresponding game times, such as the fluctuation pattern in the symbol display device 61 and the presence / absence of reach, based on the game times command.

  In addition to the counters described above, a second specific lamp random number counter used for lottery for determining whether or not to open the electric accessory provided in the operation port 55 is provided. The value of the second specific lamp random number counter at that time is acquired at the timing when a winning occurs, and a lottery is performed as to whether or not to open the electric accessory based on the acquired value.

  Returning to the description of FIG. 7, the power interruption monitoring board 202, the payout control device 162, and the sound lamp control device 113 are connected to the output side of the MPU 211. Various commands such as a prize ball command are output to the payout control device 162. Various commands for game times are output from the main control board 201 to the sound lamp control device 113.

  The power interruption monitoring board 202 relays between the main control board 201 and the power supply and launch control device 163, and monitors the voltage of DC + 24V that is the maximum voltage output from the power supply and launch control device 163. When this voltage is + 22V or more, a HI level signal as a non-interruptible signal (first information) is output (transmitted) to the main control board 201, and when this voltage becomes less than + 22V, the power is cut off. And a LOW level signal as a power failure signal (second information) is output (transmitted) to the main control board 201. The main control board 201 confirms the input of the LOW level signal in a predetermined manner, and executes a power interruption process (power failure process) to be described later based on the confirmation result.

  The payout control device 162 controls the payout device 154 to pay out a predetermined game ball based on a prize ball command or the like input from the main control board 201.

  The power supply and launch control device 163 is connected to, for example, a commercial power supply (external power supply) in a game hall or the like via the back pack substrate 156. Based on the external power supplied from the commercial power supply, the operating power required for each of the main controller 122, the payout controller 162, etc. is generated, and the generated operating power is supplied through the path indicated by the double line arrow. To do. As its outline, the power supply and launch control device 163 takes in the AC 24 volt power supplied via the back pack substrate 156, and drives the various sensors, motors, etc. DC + 12V voltage, logic DC + 5V voltage Are generated, and these DC + 12V voltage and DC + 5V voltage are supplied to the main controller 122, the payout controller 162, and the like.

  A game ball launching mechanism 40 is connected to the output side of the power source and launch control device 163. Then, according to the operation of the game ball launch handle 41 by the player, the launch control of the game ball launch mechanism 40 is executed. The game ball launching mechanism 40 is driven when predetermined launch conditions are met.

  In addition, the power supply and launch control device 163 is equipped with a power supply unit for power interruption. When the power of the pachinko machine 10 is in an OFF state or when a power interruption occurs in a commercial power supply (from an external power supply) In the case where the power supply is interrupted), the storage holding power is supplied from the power interruption power supply unit to the RAM 213 of the main control board 201. Therefore, even in such a situation, the information stored in the RAM 213 is stored and held without being erased.

  The sound lamp control device 113 controls the various lamp units 23, 24, 25, the speaker unit 26, and the display control device 214 based on various commands output from the main control board 201. The display control device 214 controls the symbol display device 61 based on the display command input from the sound lamp control device 113.

  Here, the magnetic sensor module 81 is electrically connected to the input side and the output side of the main control board 201. The magnetic sensor module 81 includes a magnetic sensor 221 and an MPU 222 as a one-chip microcomputer that is an arithmetic device that processes magnetic detection information in the magnetic sensor 221. The magnetic sensor 221 and the MPU 222 are electrically connected. The magnetic sensor 221 includes a triaxial MI element (magnetic impedance element), and can detect magnetism in a wide range with higher sensitivity than a magnetic sensor using a reed switch type or a Hall element, and in any direction. It is possible to specify whether magnetism has been applied.

  The MPU 222 includes a ROM 223 that stores a control program executed by the MPU 222, fixed value data, and the like, and a RAM 224 that is used as a work memory or the like. When magnetism is applied to the magnetic sensor 221, the impedance of the magnetic sensor 221 changes, and the MPU 222 analyzes the amount of change in the impedance and calculates it as a magnetic detection value. Then, after executing a predetermined process for determining whether or not to set the magnetic detection state based on the detection value, when the magnetic detection state is set, the HI level as the magnetic detection state signal is sent to the MPU 211 of the main controller 122. When a signal is output and the magnetic detection state is not set, a LOW level signal is output. However, the output mode of the signal is not limited to this, and the relationship between the HI level signal and the LOW level signal may be reversed. The above processing of the MPU 222 will be described in detail later.

  The MPU 222 has a function of executing an offset process for calibrating the magnetic detection value based on a signal from the main control board 201. Although details of this processing will be described later, the MPU 211 of the main control board 201 switches the output mode as the offset signal from the LOW level signal to the HI level signal when the magnetic sensor module 81 is to execute the offset processing. If the offset processing is not to be executed, the HI level signal is switched to the LOW level signal and output. However, the output mode of the signal is not limited to this, and the relationship between the HI level signal and the LOW level signal may be reversed.

<Processing Configuration in MPU 211 of Main Control Board 201>
Next, each control process executed by the MPU 211 of the main control board 201 will be described. The processing of the MPU 211 is roughly classified into main processing that is activated when the power is turned on and timer interrupt processing that is periodically activated.

<Main processing>
First, the main process that is started upon reset at power-on will be described with reference to the flowchart of FIG.

  First, in step S101, power-on wait processing is executed. In the power-on wait process, for example, the process waits without progressing to the next process until 1 sec elapses after the main process is activated. In the subsequent step S102, access to the RAM 213 is permitted, and the internal function register of the MPU 211 is set in step S103.

  Thereafter, in step S104, it is determined whether or not the RAM erase switch 166 provided in the power supply and launch control device 163 is turned on. In subsequent step S105, it is determined whether or not the power failure flag is set to “1” in the RAM 213. judge. In step S106, a RAM determination value is calculated. In subsequent step S107, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is a checksum value at a work area address in the RAM 213, for example. It is also possible to determine the validity of data stored and held based on whether or not the keywords written in a predetermined area of the RAM 213 are correctly stored.

  In the pachinko machine 10, for example, when RAM data is initialized when the power is turned on, such as when the hall starts business, the power is turned on while the RAM erase switch 166 is pressed. Therefore, if the RAM erase switch 166 is pressed, the process proceeds to step S108. Similarly, when the information on occurrence of power shut-off is not set, or when abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to step S108. In step S108, the RAM 213 is cleared as initialization of the RAM 213. Thereafter, the process proceeds to step S109.

  On the other hand, if the RAM erase switch has not been pressed, step S109 is executed without executing step S108 on condition that the power failure flag is set to “1” and the checksum is normal. Proceed to

  In step S109, a power-on setting process is executed. In the power-on setting process, a predetermined area of the RAM 213 such as initialization of a power failure flag is set to an initial value, and a command for causing each control device to execute a process at power-on is transmitted. Specifically, a command corresponding to the current gaming state is transmitted to the sound lamp control device 113 in order to recognize the current gaming state, and the initial state of the paying device 154 is transmitted to the payout control device 162. Send a command to execute the driving test. Note that the power-on process in the power source and launch control device 163 is triggered by a command from the main control device 122 because the power source and launch control device 163 is disposed upstream of the main control device 122 from the commercial power source. Instead, the switching operation of the power switch 156a or the power supply from the island facility is changed from OFF to ON. In the power-on process of the power supply and launch control device 163, an initial drive test of the launch solenoid and the ball feeder in the game ball launch mechanism 40 is executed. In step S109, an interrupt permission is set to permit the generation of the timer interrupt process.

  In subsequent step S110, a sensor confirmation process for confirming whether or not the magnetic sensor module 81 has been normally activated is executed. Such processing will be described in detail later.

  Thereafter, the process proceeds to the remaining processes in steps S111 to S114. In other words, the MPU 211 is configured to periodically execute the timer interrupt process, but a remaining time is generated between one timer interrupt process and the next timer interrupt process. The remaining time varies depending on the processing completion time of each timer interrupt process, but the remaining processes in steps S111 to S114 are repeatedly executed using such irregular time. In this regard, it can be said that the remaining processes in steps S111 to S114 are non-periodic processes that are performed irregularly.

  In the remaining process, first, in step S111, an interrupt prohibition setting is performed to prohibit the generation of the timer interrupt process. In the subsequent step S112, a random number initial value update process for updating the random number initial value counter CINI is executed, and a change counter update process for updating the change type counter CS is executed in step S113. In these update processes, the current numerical information is read from the corresponding counter in the RAM 213, the process of adding 1 to the read numerical information is executed, and then the process of overwriting the read-out counter is executed. In this case, each counter value is cleared to “0” when it reaches the maximum value. Thereafter, in step S114, an interrupt permission setting for switching from a state in which the generation of the timer interrupt process is prohibited to a state in which the timer interrupt process is permitted is performed. If the process of step S114 is performed, it will return to step S111 and will repeat the process of step S111-step S114.

  Here, as described above, in the remaining process, only the initial random number value update process and the variation counter update process are set so as to be sandwiched between the interrupt disable process and the interrupt enable process. The timing at which the interrupt process is started is always immediately before step S111. Then, after the timer interrupt process is completed, it is only necessary to start from step S111, and the return address after the timer interrupt process is unambiguous. Therefore, it is not necessary to store the current return address at the start of the timer interrupt process, and the processing load at the start of the timer interrupt process is reduced.

  In addition, since the timer interrupt process does not occur during the calculation of predetermined data in the MPU 211, when the timer interrupt process is started, the data stored in the register of the MPU 211 at that time is saved in the RAM 213. Similarly, it is not necessary to execute the process of restoring the data to the register of the MPU 211 when the timer interrupt process ends. Therefore, the processing load at the start of the timer interrupt process is reduced, and the processing load at the end of the timer interrupt process is also reduced.

  In addition, since timer interrupt processing is not started during the update of the random number initial value counter CINI or during the update of the variation type counter CS, these counters are not updated during the timer interrupt processing. It is possible to prevent numerical information from being acquired and further update processing from being executed.

<Timer interrupt processing>
Next, timer interrupt processing will be described with reference to the flowchart of FIG.

  Here, a hardware configuration for periodically executing timer interrupt processing in the MPU 211 will be described. The main control board 201 is provided with a clock circuit as pulse signal output means for outputting a pulse signal at a predetermined cycle, and further, a frequency dividing circuit so as to exist in the middle of a signal path between the clock circuit and the MPU 211. Is provided.

  The frequency dividing circuit functions as frequency changing means for changing the cycle of the pulse signal from the clock circuit, and is configured to output a pulse signal for specifying the start timing of the timer interrupt processing by the MPU 211. That is, the pulse signal is supplied from the frequency dividing circuit to the MPU 211 at intervals of a specific cycle of 4 msec. The MPU 211 executes a process for confirming the occurrence of a specific signal form such as the rise or fall of the pulse signal, and starts and executes the timer interrupt process with at least one condition that the occurrence of the specific signal form is confirmed. To do.

  In this case, when the occurrence of the specific signal form is confirmed in the situation where the start of timer interrupt processing is prohibited, the timer is changed when the interrupt is permitted from the state where the interrupt is prohibited. Interrupt processing is started. In other words, depending on the execution status of the process in the MPU 211, there is a case where the next timer interrupt process starts after 4.1 msec from the start of the previous timer interrupt process. The timer interrupt process is started after 3.9 msec from the start of the immediately preceding timer interrupt process.

  However, since the output of the pulse signal from the frequency divider circuit is performed at a specific cycle of 4 msec regardless of the progress of the processing in the MPU 211, the timer interrupt processing is basically started at a specific cycle. The processing configuration of the MPU 211 is such that the timer interrupt process at a predetermined timing is started after a period exceeding a specific period since the previous timer interrupt process was started. The timer interrupt processing is set so that the portion exceeding the specific period is absorbed, and the timer interrupt processing at the next timing is started at the timing when the input of the pulse signal is confirmed.

  In the timer interrupt process, first, a power failure information storage process is executed in step S201. In the power failure information storage process, it is monitored whether or not a power failure signal corresponding to the occurrence of power interruption is received from the power failure monitoring circuit 203, and when the occurrence of a power failure is specified, the power failure process is executed.

  In the subsequent step S202, a sensor correction process for causing the magnetic sensor module 81 to calibrate the magnetic detection value is executed. Such processing will be described in detail later.

  In a succeeding step S203, a lottery random number update process is executed. In the lottery random number update process, the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and the electric accessory release counter C4 are updated. Specifically, after executing the process of sequentially reading the current numerical information from the jackpot random number counter C1, the jackpot type counter C2, the reach random number counter C3, and the electric accessory release counter C4, and adding 1 to each of the read numerical information Then, a process of overwriting the reading source counter is executed. In this case, each counter value is cleared to “0” when it reaches the maximum value.

  Thereafter, in step S204, the random number initial value updating process is executed in the same manner as in step S112, and in step S205, the variation counter updating process is executed in the same manner as in step S113. In a succeeding step S206, a game stop determination process is executed. In the game stop determination process, it is monitored whether or not the progress of the game is to be stopped. If the progress of the game is to be stopped, the execution of the process for progressing the game is stopped.

  Thereafter, in step S207, it is determined whether or not the progress of the game is stopped, and the processing after step S208 is executed on the condition that the progress of the game is not stopped.

  In step S208, port output processing is executed. In the port output process, when output information has been set in the previous timer interrupt process, a process for performing output corresponding to the output information to various drive units is executed. In subsequent step S209, a reading process is executed. In the reading process, various signals such as an inner frame opening signal from the inner frame opening switch 13a, a front door frame opening signal from the front door frame opening switch 14a, and a detection state signal from the magnetic sensor module 81 other than the power failure signal and the winning signal. Reads the signal and stores the read information for use in future processing. The reading process of the detection state signal from the magnetic sensor module 81 will be described in detail later.

  In the subsequent step S210, a signal received from each winning detection sensor is read, and a winning detection process for performing processing corresponding to the read information is executed. In step S211, timer update processing for updating the numerical information of predetermined timer counters provided in the RAM 213 collectively is executed.

  In subsequent step S212, a fraud detection process for monitoring whether or not a predetermined event set as a fraud monitoring target has occurred is executed. In such processing, magnetic detection processing is performed when magnetism is applied for an unauthorized purpose. The contents of the magnetic detection process will be described later in detail.

  In the subsequent step S213, a launch control process for executing launch control of the game ball is executed. In this process, when it is possible to launch a game ball, the launch solenoid and the ball feeding device of the game ball launch mechanism 40 are driven and controlled, and the game ball is launched with a launch intensity based on the operation amount of the game ball launch handle 41. Let it fire.

  In step S214, as input state monitoring processing, disconnection confirmation of each winning detection sensor and opening confirmation of the gaming machine main body 12 and the front door frame 14 are performed based on the information read in the reading processing in step S209.

  In the subsequent step S215, special figure special electric control processing for performing execution control of game times and execution control of the opening / closing execution mode is executed. In the special figure special power control process, when a winning to the operation port 55 occurs in a situation where the number of pieces of holding information stored in the holding ball storage area 213b is less than the upper limit number, a big hit random number counter C1 at that time, A process of storing each piece of numerical information of the big hit type counter C2 and the reach random number counter C3 as holding information in the holding ball storage area 213b in time series is executed. Also, in the special figure special electric control process, whether or not the hold information corresponds to the big win is determined on the condition that the hold information is not stored during the game rotation and the opening / closing execution mode and is stored. If it corresponds to the process and the jackpot winning, a distribution determination process for determining which jackpot result the hold information corresponds to is executed. In addition, in the special figure special power control process, not only the success / failure determination process and the distribution determination process, but if the hold information does not correspond to the big win, whether the hold information corresponds to the occurrence of reach. A reach determination process is performed, and a duration selection process for selecting the duration of the game times using the numerical information of the variation type counter CS at that time is executed. Then, the variation command including the duration information corresponding to the result of each process and the type command including the game result information are transmitted to the sound lamp control device 113 and the first specific lamp unit 63 emits light. Start switching colors. As a result, one game round is started, and an effect for game round is started on the first specific lamp unit 63 and the symbol display device 61.

  If the jackpot is won, or if the jackpot is not won and the result of the reach determination process is a result corresponding to the occurrence of reach, the game information is continued using the numerical information of the variation type counter CS. By determining the duration corresponding to the occurrence of the reach display as the time, the voice lamp control device 113 can identify the type of reach display from the change command.

  Also, in the special figure special electric control process, during the execution of one game round, it is determined whether or not it is the end timing of the game round. If it is the end timing, the display corresponding to the game result is performed. Then, the process of ending the game round is executed. In this case, a final stop command indicating that the game round should be ended is transmitted to the sound lamp control device 113. Further, in the special figure special electric control process, when the result of the game times is a result corresponding to the transition to the opening / closing execution mode, a process for starting the opening / closing execution mode is executed. At the start, an opening command indicating that the opening / closing execution mode is started is transmitted to the sound lamp control device 113. In the special figure special electric control process, a process for starting each round game and a process for ending each round game are executed. In each of these processes, an open command indicating that the round game is started is transmitted to the sound lamp control device 113, and a close command indicating that the round game is ended is transmitted to the sound lamp control device 113. Further, in the opening / closing execution mode, the drive unit of the variable winning device 54 is driven and controlled in order to open and close the variable winning device 54 at intervals of a predetermined period. Further, in the special figure special electric control process, when the opening / closing execution mode is ended, an ending command indicating that is transmitted to the sound lamp control device 113, and the success / failure lottery mode and the support mode after the opening / closing execution mode are set. Execute the process.

  After executing the special figure special electric control process of step S215 in the timer interruption process, the normal figure normal electric control process is executed in step S216. In the ordinary power transmission control process, when winning to the through gate 56 occurs, a process for obtaining numerical information of the electric accessory release counter C4 is executed and the numerical information is stored. Then, the numerical value information is determined to be released, and further, the opening determination is used as a trigger to execute a process for producing a general-purpose effect. Further, based on the result of the open determination, the drive unit of the electric accessory is controlled to be opened and closed to open and close the electric accessory of the operation port 55.

  In the subsequent step S217, the output information for updating the display content of the first specific lamp unit 63 is set based on the processing results of the immediately preceding steps S215 and S216, and the display content of the second specific lamp unit 64 is set. Set the output information to update.

  In the subsequent step S218, a demonstration display process is executed to make the display content of the symbol display device 61 for standby display in a situation where both the game times and the opening / closing execution mode are not executed. In step S219, The contents of the command and signal received from the payout control device 162 are confirmed, and a payout state reception process for performing a process corresponding to the confirmation result is executed. In step S220, a payout output process for setting a prize ball command as an output target is executed.

  In subsequent step S221, external information setting processing is executed so as to control the start and end of output of an external signal in accordance with the processing results of various processing executed in the current timer interrupt processing. In step S222, processing for editing the test test information is executed.

  When an affirmative determination is made in step S207, or after the processing of steps S208 to S222 is executed, the process proceeds to step S223. In step S223, an interrupt end declaration is set. In the MPU 211, once the timer interrupt process is started, it is determined that an interrupt end declaration is set as one of the conditions for starting the next timer interrupt process. In step S223, the next timer interrupt process is set. Set interrupt termination declaration to enable execution of interrupt processing. In step S224, interrupt permission is set. In the MPU 211, once the timer interrupt processing is started, the interrupt is disabled. Therefore, in step S224, interrupt permission is set to enable execution of the next timer interrupt processing. Thereafter, the timer interrupt process is terminated.

<Processing related to magnetic detection>
Next, each process related to magnetic detection will be described. First, processing executed in the MPU 222 of the magnetic sensor module 81 will be described. The processing of the MPU 222 is roughly divided into a startup process that is started when the power is turned on, and a normal process that is started after the startup process ends and periodically (for example, every 20 msec).

  First, the start-up process started when the power is turned on will be described with reference to the flowchart of FIG.

  When the power of the pachinko machine 10 is turned on, read processing of each input terminal is executed in step S301. As an input terminal of the magnetic sensor module 81, a detection distance setting terminal is provided in addition to an offset terminal that receives an offset signal output from the main control board 201. In step S301, based on a signal input from the main control board 201 to the detection distance setting terminal, it is determined how wide the area where the magnetic sensor 221 detects magnetism is set.

  Here, the relationship between the width of the detection region set in step S301 and the detection sensitivity will be described with reference to FIG. 12A is an explanatory diagram for explaining the positional relationship between the standard magnet HG (surface magnetic flux 430 mT) for explaining the detection region and the magnetic sensor module 81, and FIG. 12B is a diagram showing the standard magnet HG. FIG. 13 is a diagram showing detected values in the magnetic sensor module 81 when arranged at the position in FIG.

  As already described, the magnetic sensor module 81 is configured to calculate the amount of change in impedance in the magnetic sensor 221 as a detected value (binding density). As shown in FIG. 12B, the detection value detected by the magnetic sensor module 81 is inversely proportional to the square of the distance between the magnetic sensor module 81 and the standard magnet HG. In the magnetic sensor module 81, a plurality of sensitivity levels (four levels in the present embodiment) indicating the width of the detection region are set, and in step S301, based on the signal from the main control board 201. The sensitivity level is set to one of the sensitivity levels 1 to 4 of the plurality of levels. A threshold value is set for each of the plurality of sensitivity levels 1 to 4, and the MPU 222 does not enter a magnetic detection state when it is lower than each threshold value. Each threshold value is set so that the sensitivity level 1 is the lowest and the sensitivity level 4 is the highest, and the threshold value increases in the order of sensitivity level 1, sensitivity level 2, sensitivity level 3, and sensitivity level 4. Has been. In other words, it can be said that sensitivity level 1 has the highest detection sensitivity and sensitivity level 4 has the lowest detection sensitivity.

  Specifically, when the standard magnet HG is arranged at the position A in FIG. 12A, the impedance of the magnetic sensor 221 is changed by the magnetism of the standard magnet HG, but the amount of change is the sensitivity level. Even if it is smaller than the threshold value of 1 and set to any sensitivity level, the magnetic detection state is not set. When the standard magnet HG is disposed at the position B, the impedance change amount is larger than the sensitivity level 1 threshold and smaller than the sensitivity level 2 threshold. Therefore, when the sensitivity level is set to 1, the magnetic detection state is set, and when the sensitivity level is set to 2 to 4, the magnetic detection state is not set. When the standard magnet HG is disposed at the position C, the amount of change in impedance is larger than the threshold of sensitivity level 2 and smaller than the threshold of sensitivity level 3. Accordingly, when the sensitivity level is set to 1-2, the magnetic detection state is set, and when the sensitivity level is set to 3-4, the magnetic detection state is set. When the standard magnet HG is arranged at the position D, the amount of change in impedance is larger than the threshold of sensitivity level 3 and smaller than the threshold of sensitivity level 4. Therefore, when the sensitivity level is set to 1 to 3, the magnetic detection state is set, and when the sensitivity level 4 is set, the magnetic detection state is set. And when the standard magnet HG is arrange | positioned in the position of E, the variation | change_quantity of an impedance becomes larger than the threshold value of any sensitivity level 1-4, and when it is set to any sensitivity level 1-4. Even if there is a magnetic detection state.

  Specifically, with respect to the threshold values of the sensitivity levels 1 to 4, the amount of change in impedance when the standard magnet having the surface magnetic flux of 430 mT is arranged at a position separated from the magnetic sensor 221 of the magnetic sensor module 81 by 20 cm is the sensitivity level 1. This corresponds to a threshold value, which is 17 cm at sensitivity level 2, 15 cm at sensitivity level 3, and 12 cm at sensitivity level 4. However, the number of each of these threshold values and sensitivity levels is arbitrary.

  In addition, from the relationship with the threshold value in each of the sensitivity levels 1 to 4, the magnetism detection in the magnetic sensor module 81 indicates that the amount of change in impedance is equal to or greater than the threshold value of the set sensitivity level.

  More specifically, the sensitivity level setting switch is provided with a sensitivity level setting switch (not shown) on the back surface of the inner frame 13, and the game hall manager or the like operates the sensitivity level setting switch to operate the sensitivity level. Can be set. The sensitivity level setting switch can be adjusted according to the memories 1 to 4. For example, when the sensitivity level is changed from 1 to 4, the memory to be adjusted is changed from 1 to 4. The sensitivity level can be changed. The configuration relating to the change of the sensitivity level is not limited to this, and for example, a configuration in which the sensitivity level can be set by the number of operations, or a configuration in which a switch is provided in the magnetic sensor module 81 may be used. When the magnetic sensor module 81 is provided with a switch, a configuration in which the main controller 122 outputs a signal (detection sensitivity setting signal) instructing the magnetic sensor module 81 to set a sensitivity level can be omitted.

  Returning to the description of the start-up process of the magnetic sensor module 81 (FIG. 11), in step S301, based on the signal from the main control board 201, each of the sensitivity levels 1 to 4 described above as the width of the detection area of the magnetic sensor 221. Among these, sensitivity level 1 is set. That is, in the pachinko machine 10, the size of the detection area of the magnetic sensor 221 is set to be the widest area. Thereby, it becomes possible to specify the illegal act by a magnet in a wide range. Although detailed explanation is omitted, the sensitivity level to be set can be changed by the hall manager of the game hall, and the setting of the signal output from the main control board 201 to the detection distance setting terminal of the magnetic sensor module 81 The sensitivity level can be changed by changing. For example, in a game hall under an overpass or the like, it is assumed that the magnetic field changes greatly due to passage of a train. In such a case, erroneous detection of the magnetic sensor module 81 can be suppressed by lowering the sensitivity level. ing.

  After executing the process of step S301, the first offset process is executed in step S302. Here, the first offset processing will be described with reference to FIGS. 13 and 14. FIG. 13 is an explanatory diagram for explaining the offset processing of the magnetic sensor module 81, and FIG. 14 is a flowchart showing the first offset processing.

  First, the contents of the offset process will be briefly described.

  The offset process is a process of calibrating the detected value of magnetism currently detected by the magnetic sensor 221 as a zero value. Specifically, as shown in FIG. 13, when the sensitivity level (x) is set to any one of the sensitivity levels 1 to 4, a predetermined period from the Ta timing to the Tb timing for the magnetism above the threshold value. (In this embodiment, 300 msec) is a process of measuring, and updating a numerical value obtained by dividing the integrated value by a predetermined period to the 0 value of the detected value.

  By the way, in the offset process, when the magnetism more than the predetermined reference value stored in the ROM 223 in the MPU 222 is detected, the width between the maximum value H and the minimum value L of the detected value becomes the predetermined value or more during the offset process. In the case, an error value (minus value) is input as a detection value as error processing. Specifically, depending on when strong magnetism (for example, magnetism corresponding to the case where the standard magnet HG is disposed within 10 cm) is detected, or when the inner frame 13 is opened and closed during the offset process, etc. If the detected value fluctuates (for example, if the corresponding detected value fluctuates when the standard magnet HG placed 10 cm away from the magnetic sensor 221 moves in the direction of 20 cm away), an error occurs. Execute the process.

  Further, as shown in FIG. 13, the threshold value T of the sensitivity level (x) does not change before and after the offset process. Therefore, processing such as resetting the sensitivity level (x) by executing the offset processing is not necessary, and the processing can be simplified.

  Now, the first offset process in step S302 in the startup process (FIG. 11) of the magnetic sensor module 81 will be described. First, in step S401, the magnetism detection value is calculated from the current impedance in the magnetic sensor 221 of the magnetic sensor module 81. A process of calculating and integrating the detected values is executed. Specifically, a process of integrating the current detection value in the detection value integration area provided in the RAM 224 is executed. In the integration process, if the detected value to be integrated is equal to or greater than the predetermined reference value stored in the ROM 212, the error value is input to the detected value as error processing without performing integration. In this case, an error determination is made in a process (step S303) for determining whether or not the offset process described later has been normally executed.

  In a succeeding step S402, it is determined whether or not it is the end timing of the first offset process. In the pachinko machine 10, the end timing of the first offset process is a timing when 300 msec has elapsed since the start of the first offset process. A soft random number is used for the determination of the timing. However, the determination may be made using a clock circuit or the like.

  If it is not the end timing in step S402, the process returns to step S401 to repeat the detection value integration process. In addition, in the integration process of step S401, the maximum value and the minimum value are stored as numerical information of the detection values to be integrated. And when integrating the numerical information exceeding the stored maximum value or the numerical information below the minimum value, a process of updating the maximum value or the minimum value is executed.

  By making an affirmative determination in step S402, the process proceeds to step S403. In step S403, a process of averaging numerical information in the detection value integration area of the RAM 224 is executed. Also, during the averaging process, the width of the stored maximum value and the minimum value is calculated, and when the width exceeds the predetermined value, the averaging process is not performed and the detected value is set as an error process. An error value is entered. In this case, an error determination is made in a process (step S303) for determining whether or not the offset process described later has been normally executed.

  In the subsequent step S404, a process of overwriting the 0-value information storage area provided in the RAM 224 with the process result of step S403 is executed, and the first offset process is terminated. However, in step S404, if an error value is input as the detection value in the process in step S401 or step S403, the first offset process is terminated without executing the overwriting process.

  Returning to the description of the start-up process (FIG. 11), after the offset process is executed in step S302, it is determined in step S303 whether the first offset process of step S302 has been normally executed. In this case, the success / failure result of the offset process can be determined by checking the detection value and determining whether an error value is input in step S401 or step S403.

  If a positive determination is made in step S303, the start-up process is terminated. On the other hand, if it is determined in step S303 that the offset process cannot be normally executed, that is, if an error value is input as the detection value, the process proceeds to step S304. In step S304, each storage area of the RAM 224 is cleared as initialization processing of the RAM 224, and in a subsequent step S303, the detection state signal is set to the HI level signal. The detection state signal is set to a LOW level signal as an initial setting. Then, the process returns to step S302 and the first offset process is executed again. That is, until the first offset process is successful, the start-up process does not end and the normal process described later is not started. In addition, when the start-up process ends, the detection state signal is always a LOW level signal.

  Although details will be described later, the main control device 122 can identify whether or not the first offset processing is successful by confirming the detection state signal. If the first offset process is an error, a predetermined notification is given through the sound lamp control device 113 and the display control device 214. As a result, the hall manager can recognize that the magnetic sensor module 81 is not normally activated, and can perform predetermined measures such as removing the magnet that caused the error.

  Further, when the offset process cannot be normally executed again without performing a predetermined measure such as removing the magnet causing the error by the hall manager, step S302 → step S303 → step S304 → step S305 → Step S302 is looped. On the other hand, if the cause of the error is that the fluctuation range of the detected value exceeds a predetermined value, the offset process is likely to proceed to the end of the start-up process, for example, an error occurs. In this case, it is possible to execute the start-up process more efficiently than in a configuration where the power needs to be turned on again.

  Next, the normal process started after the start-up process and started periodically will be described with reference to the flowchart of FIG.

  In the normal process, first, a magnetic detection process is executed in step S501. Here, the magnetic detection processing in step S501 will be described with reference to the flowchart in FIG.

  In the magnetic detection process, first, in step S601, it is determined whether or not magnetism is detected. Specifically, it is determined whether or not the amount of change in impedance is greater than or equal to a set sensitivity level threshold. If magnetism is detected, orientation filter processing is executed in the subsequent step S602. This process is a process for specifying the magnetic direction detected by the magnetic sensor 221 and extracting only the direction to be detected. More specifically, the detection value of the three-axis magnetic sensor 221 is analyzed, and only the magnetism applied from the front of the pachinko machine 10 is extracted. In subsequent step S603, it is determined whether or not the detected magnetism is applied from the front as a result of the process in step S602. If the magnetism is applied from the front, in step S604, a process of updating the numerical information of the detection counter K provided in the RAM 224 so as to add 1 is executed. The detection counter K is a counter for the MPU 222 to specify the number of times the magnetism applied from the front is detected. In a succeeding step S605, it is determined whether or not the numerical value information of the detection counter K is 3 as a result of the process in the step S604. If the numerical information of the detection counter K is 3, the detection state signal is set to the HI level signal as the magnetic detection state in step S606, and the magnetic detection process is terminated. As a result, the MPU 211 of the main control device 122 can specify that the magnetic sensor module 81 is in a magnetic detection state. If the numerical information of the detection counter K is not 3 in step S605, the magnetic detection process is terminated as it is.

  If a negative determination is made in step S601 or step S603, a process of updating the numerical information of the detection counter K to 0 is executed in step S607. In subsequent step S608, as a process for canceling the magnetic detection state, the detection state signal is set to a LOW level signal, and the magnetic detection process is terminated. Thereby, the MPU 211 of the main controller 122 can specify that the magnetic sensor module 81 is not in the magnetic detection state.

  That is, the magnetic detection process is configured to set the magnetic detection state when magnetism is continuously detected in three processing times. The normal process including the magnetic detection process is started periodically (every 20 msec) as described above. In this configuration, when magnetism is continuously applied for 60 msec or more, or the processing timing of the magnetic detection process and 3 When the magnetism is applied continuously and synchronously, the magnetic detection state is set. On the other hand, for example, the magnetism generated by driving a launching solenoid or the like in the game ball launching mechanism 40 is shorter than 60 msec in one driving cycle. The launch solenoid or the like is configured to fire a game ball by driving at a period of 0.6 sec as described above, but does not synchronize with the processing timing of the magnetic detection process three times in succession. On the other hand, the improper magnetism that can guide the game ball to the operation port 55 or the like is assumed to be continuously applied for 60 msec or more in consideration of the weight of the game ball and the flow speed. Therefore, even when magnetism emitted from each drive unit is detected, the magnetism detection state is not immediately set, and it is possible to distinguish from magnetism that is improperly applied improperly.

  Returning to the description of the normal process (FIG. 14), after the magnetic detection process is executed in step S501, an offset signal reading process is executed in step S502. Specifically, when the output mode of the offset signal from the main control board 201 is a LOW level signal, the information (for example, “0”) is stored in the RAM 224, and when it is a HI level signal, the information ( For example, “1”) is stored in the RAM 224. In subsequent step S503, it is determined whether or not the offset signal has been switched from the LOW level signal to the HI level signal as a result of the processing in step S502. Specifically, the information indicating the output mode of the offset signal stored in the previous processing time is compared with the information indicating the output mode of the offset signal stored in the current processing time, and the output mode of the offset signal Is changed from the LOW level signal to the HI level signal.

  When an affirmative determination is made in step S503, a process of setting “1” to an in-offset flag provided in the RAM 224 is executed in step S504. The in-offset flag is a flag for specifying that the MPU 222 is in a second offset process (step S507) described later. In the subsequent step S505, a process of clearing the sensor offset counter ST provided in the RAM 224 to “0” is executed. The sensor offset counter ST is a counter for measuring the execution period of the second offset process.

  After making a negative determination in step S503, or after executing the process of step S505, the process proceeds to step S506. In step S506, it is determined whether “1” is set in the offset flag. If “1” is not set in the in-offset flag, the normal processing is terminated as it is. If “1” is set in the in-offset flag, the second offset process is executed in step S507, and then the normal process ends.

  Here, the second offset process of step S507 will be described with reference to the flowchart of FIG.

  First, in step S701, similarly to step S401 in the first offset process (FIG. 14), a process of integrating the current magnetism detection values is executed. In the subsequent step S702, a process of adding “1” to the sensor offset counter ST is executed.

  After performing the process of step S702, it is determined in step S703 whether or not the numerical information of the sensor offset counter ST is “15” as a result of the process of step S702. If the numerical information of the sensor offset counter ST is not “15”, the second offset process is terminated as it is. If the numerical information of the sensor offset counter ST is “15”, the process proceeds to step S704.

  In step S704, the detection value averaging process during the offset process is executed in the same manner as the process of step S403 in the first offset process (FIG. 14). In a succeeding step S705, a process of clearing the offset flag to “0” is executed. Then, in step S706, it is determined whether or not the current offset process (second offset process) has succeeded, similar to the process in step S303 in the startup process (FIG. 11). If the second offset process is successful, in step S707, a zero value overwrite process is executed in the same manner as in step S404 in the first offset process. Thereafter, the detection state signal is set to a LOW level signal, and the second offset process is terminated. If a negative determination is made in step S706, that is, if the second offset process is an error, the detection state signal is set to the HI level signal in step S709, and the second offset process ends.

  That is, the magnetic sensor module 81 is configured to execute the first offset process in the start-up process and execute the second offset process in the normal process on the condition that the offset signal is switched.

  The first offset process executed in the start-up process is executed when the magnetic sensor module 81 is turned on, that is, when the pachinko machine 10 is turned on. The power of the pachinko machine 10 is normally driven by the pachinko machine 10. It is not always the case that it is thrown in. As described above, the pachinko machine 10 is installed in the game hall in parallel with the island equipment, and by turning on the power of the island equipment, it is possible to simultaneously turn on the power of a plurality of pachinko machines 10 installed in the island equipment. It is possible. In this case, for example, the power may be turned on with the inner frame 13 of the pachinko machine 10 closed, or the power may be turned on with the inner frame 13 open for internal inspection of the pachinko machine 10 or the like. is there. Further, the power switch 156a is not limited to the case where the power of the pachinko machine 10 is turned on by turning on the power of the island facility. Since it is provided at a position where it can be operated with 13 open, the inner frame 13 is necessarily open when the power is manually turned on.

  Here, the relationship between the detection area in the magnetic sensor module 81 and the mode in which the pachinko machine 10 is attached to the island facility will be described with reference to FIG. FIG. 18A is a view of the pachinko machine 10 for explaining the detection area of the magnetic sensor module 81 as viewed from above, and FIG. 18B illustrates how the pachinko machine 10 is attached to the island facility. It is the figure which looked at the hall island equipment for doing from the upper part.

  As shown in FIG. 18A, the magnetic sensor module 81 is provided in contact with the back surface of the game board 50 so that the magnetic sensor 221 faces forward.

  As an act of applying magnetism for an unauthorized purpose, an act of applying magnetism from the front of the pachinko machine 10 is assumed. However, the area to be detected by the magnetic sensor module 81 is set to include the front of the pachinko machine 10. ing. In contrast, as described above, behind the game board 50, the main control device 122, the power and launch control device 163, the sound lamp control device 113, the display control device 214, the payout control device 162, and the like are electrically controlled. Various control devices and various drive units are provided (see FIG. 3). And in the magnetic sensor module 81, the various control apparatuses and various drive parts which are arrange | positioned back are excluded from the detection object by the azimuth | direction filter process (step S602). Therefore, the magnetism generated from these various control devices and various drive units is not targeted for detection, and it is possible to suitably detect the magnetism applied for illegal purposes.

  On the other hand, as shown in FIG. 18B, the pachinko machine 10 is generally installed in parallel with island facilities in a game hall. In addition, as already described, the inner frame 13 to which the magnetic sensor module 81, the various control devices, and the various drive units are attached can be rotated forward with respect to the outer frame 11 (see FIG. 2). In this case, when the inner frames 13 of the pachinko machines 10 arranged in parallel are opened, the back surface of the inner frame 13 in one pachinko machine 10 is positioned in front of the inner frames 13 of the other pachinko machines 10. As described above, various control devices are attached to the back surface of the inner frame 13, and the magnetic sensor module 81 is set as a detection target area in front of the inner frame 13, and the magnetic sensor module of the other pachinko machine 10. The various control devices and various drive units of the one pachinko machine 10 are included in the area to be detected 81.

  Accordingly, when the power of the pachinko machine 10 is turned on when the inner frame 13 is in the open state, the first offset processing at the time of turning on the power in the magnetic sensor module 81 is also performed with the inner frame 13 opened. It will be. In this case, as described above, since various control devices and various drive units of the other pachinko machine 10 are included in the detection target area of the magnetic sensor module 81, magnetism generated from these various control devices and various drive units. In consideration of this, calibration of 0 value, which is a reference for the detection value, is performed.

  In particular, when the pachinko machine 10 is powered on, various control devices execute initial drive tests of various drive units, and magnetism is also generated by the initial drive test. Further, the magnetic field changes by changing from a state in which no voltage is applied to the various control devices to a state in which a voltage is applied as the power is turned on. When the power of the pachinko machine 10 is turned on when the inner frame 13 is in an open state, the first offset processing is not preferable because it also takes into account changes in magnetism and magnetic fields accompanying the power on. .

  On the other hand, when the magnetic sensor module 81 is configured not to execute the first offset process when the power is turned on, in order to solve the above problems, after the initial drive test of each drive unit at the time of power-on, When the inner frame 13 is in the closed state, the offset process needs to be executed. However, in this case, whether or not the inner frame 13 is in a closed state is determined by a physical state displacement such as whether the inner frame opening switch 13a is in an ON state or an OFF state. There is concern about the act of holding the inner frame opening switch 13a in the OFF state. Further, when the incorrect jig is removed while applying magnetism to the magnetic sensor module 81, the offset process is performed at this timing, so that the zero value serving as a reference for detecting magnetism is shifted to the plus side. In other words, the state in which magnetism is applied is a zero value, and the state cannot be set as a magnetic detection state. In addition, since the threshold of the sensitivity level is also shifted, even if magnetism is further applied, the magnetic detection state cannot be set in a range not exceeding the threshold. Therefore, it can be said that an illegal act of guiding a game ball using a magnet or the like cannot be suitably suppressed, and it is necessary to execute an offset process when the power is turned on in order to suppress the illegal act.

  Therefore, in the pachinko machine 10, the first offset process is executed in the startup process when the magnetic sensor module 81 is turned on, and the main controller 122 again performs the offset process ( The offset signal is switched to the HI level signal at a predetermined timing to execute the second offset process. Hereinafter, processing for switching the offset signal by the MPU 211 of the main controller 122 will be described.

  First, the sensor confirmation process (step S110) in the main process (FIG. 9) executed when the pachinko machine 10 is turned on will be described with reference to the flowchart of FIG.

  In step S801, a detection sensitivity setting signal is transmitted to the detection distance setting terminal of the magnetic sensor module 81. The magnetic sensor module 81 sets the detection sensitivity in step S301 in the start-up process (FIG. 11) by receiving the signal. This signal is composed of a pulse signal of a LOW level signal and an HI level signal, and the cycle is set so as to be a different pulse signal for each detection sensitivity. In step S801, a pulse signal indicating sensitivity level 1 having the highest sensitivity among sensitivity levels 1 to 4 is transmitted. Thereby, the detection range of the magnetic sensor module 81 becomes the widest range.

  In the subsequent step S802, the process waits for a predetermined period. Specifically, it waits for a period (400 msec in this embodiment) corresponding to a period longer than one process of the first offset process in the startup process of the magnetic sensor module 81 and shorter than two processes.

  In subsequent step S803, it is determined whether or not the first first offset process in the magnetic sensor module 81 has succeeded by determining whether or not the detection state signal from the magnetic sensor module 81 is a HI level signal. If the first first offset process is successful, a process of setting “1” to the activation confirmation flag provided in the various flag storage areas 213c of the RAM 213 is executed in step S804. The activation confirmation flag is a flag for the MPU 211 to specify that the first offset process in the magnetic sensor module 81 is not in error.

  If the first first offset process is an error (step S803: YES), in step S805, a process of setting “1” to the error flag provided in the various flag storage areas 213c of the RAM 213 is executed. The error flag is a flag for the MPU 211 to specify that the first offset process or the second offset process in the magnetic sensor module 81 has an error.

  After executing the process of step S804 or step S805, the sensor confirmation process is terminated.

  As already described, in the start-up process on the magnetic sensor module 81 side (FIG. 11), if the first offset process (step S302) is not successful, the offset process is executed again, and the process is continued until the offset process is successful. The offset process is repeated. On the other hand, the main control device 122 is configured such that the subsequent processing proceeds even when the first offset processing is not successful, that is, when the detection state signal is the HI level signal.

  For example, assuming that the main sensor 122 waits until the magnetic sensor module 81 starts normally even in the main process on the main controller 122 side, as in the firing control process (step S213) and the external information setting process (step S221) in the timer interrupt process. The process relating to the progress of the game is configured not to be executed until the magnetic sensor module 81 is normally activated. In this case, for example, in the case of performing a test shot test of a game ball, the test cannot be performed unless the magnetic sensor module 81 is normally activated in spite of control not related to the magnetic sensor module 81. Therefore, it becomes inefficient. Further, when an error occurs in the first offset processing of the magnetic sensor module 81, other control devices (the audio lamp control device 113 and the display control device 214) are controlled to notify the information in which the error has occurred. It becomes difficult. Therefore, in this pachinko machine 10, even if the first first offset processing by the magnetic sensor module 81 is an error, the main control device 122 is configured to proceed with the subsequent processing, thereby suppressing the occurrence of the above-described problems. .

  Here, since the processing results of the first offset processing and the second offset processing are transmitted using a detection state signal indicating whether or not the magnetic detection state is detected, detection is performed in order to transmit the processing results. When the output mode of the state signal is switched, there is a concern about confusion with information on the magnetic detection state. Therefore, as will be described below, a characteristic feature is applied to the processing related to reading of the detection state signal.

  The detection state signal from the magnetic sensor module 81 is read in the reading process (step S209) of the timer interrupt process (FIG. 10) after the sensor confirmation process is completed. Here, the detection state signal reading process executed in the reading process will be described with reference to the flowchart of FIG.

  First, in step S901, it is determined whether or not the detection state signal from the magnetic sensor module 81 is a HI level signal. When the detection state signal is a LOW level signal (step S901: NO), it is determined in step S902 whether or not “1” is set in the activation confirmation flag. If the detection state signal is a LOW level signal and the activation confirmation flag is set to “1”, the magnetic sensor module 81 has been activated normally, and no offset processing has caused an error, and Since it is not in the magnetic detection state, the detection state signal reading process is terminated as it is.

  When “1” is not set in the activation confirmation flag (step S902: NO), the detection state signal is a LOW level signal, and “1” is set in the activation confirmation flag in the sensor confirmation process (FIG. 19). This means that the first offset process for the first time has resulted in an error, but the subsequent first offset process has succeeded. In this case, the activation confirmation flag is set to “1” in step S903, the activation confirmation command is set as a transmission target to the audio lamp control device 113 in the subsequent step S904, and the detection state signal reading process is terminated. . The activation confirmation command is transmitted to the sound lamp control device 113 in the external information setting process (step S221) of the timer interrupt process (FIG. 10). In addition, the sound lamp control device 113 transmits the activation confirmation command to the display control device 214 as it is. The processing of the sound lamp control device 113 and the display control device 214 that have received the activation confirmation command will be described later.

  If the detection state signal is a HI level signal in step S901, the process proceeds to step S905. In step S905, it is determined whether or not “1” is set in the activation confirmation flag. When the detection state signal is a HI level signal and “1” is not set in the activation confirmation flag, the magnetic sensor module 81 indicates a state in which the first offset process is in error. The status signal reading process ends.

  If “1” is set in the activation confirmation flag in step S905, the magnetic sensor module 81 has succeeded in the first offset processing, and the magnetic detection processing (step S501) and the first processing in the normal processing (FIG. 15). This means that the detection state signal has been switched to the HI level signal in one of the two offset processes (step S507). In this case, in subsequent step S906, it is determined whether or not the offset signal is output as the HI level signal from the main controller 122 side.

  Although the processing for switching the offset signal will be described later, the initial setting of the main controller 122 is set to the LOW level signal, and the second offset processing is executed for the magnetic sensor module 81 for the HI level signal. It is switched when making it. If the offset signal is output as a HI level signal, a process of setting “1” to the error flag is executed in step S907, and the detection state signal reading process is terminated. If the offset signal is not output as a HI level signal, it is determined in step S908 whether or not “1” is stored in the re-offset flag provided in the various flag storage areas 213c of the RAM 213. The re-offset flag is a flag for the MPU 211 to specify that the MPU 211 is in a state from when the MPU 211 of the main control device 122 specifies that the second offset process has an error until the second offset process is executed again. It is. If the re-offset flag is set to “1”, the detection state signal reading process is terminated as it is.

  In step S908, when “1” is not set in the re-offset flag, no error occurs in any offset processing, and the detection state signal is the HI level signal. It means that the detection state signal is switched to the HI level signal as the magnetic detection state. In this case, in step S909, a process of setting “1” to the detection state flag provided in the various flag storage areas 213c of the RAM 213 is executed, and the detection state signal reading process ends. The detection state flag is referred to in a magnetic detection process (FIG. 22) described later.

  Next, the sensor correction process (step S202) in the timer interrupt process (FIG. 10) executed at a predetermined cycle will be described with reference to the flowchart of FIG.

  In the sensor correction process, first, in step S1001, it is determined whether an offset signal is output as a HI level signal. If the offset signal is output as a LOW level signal, it is determined in subsequent step S1002 whether or not the activation confirmation flag is set to “1”. When “1” is not set in the activation confirmation flag, the magnetic sensor module 81 indicates that the first offset process is in error. In this case, “1” is set in the error flag in step S1003. It is determined whether or not. If “1” is set in the error flag, a process of clearing the error flag to “0” is executed in the subsequent step S1004, and the first error command is transmitted to the sound lamp control device 113 in step S1005. This is set as a target, and this sensor correction process is terminated.

  The first error command is transmitted to the sound lamp control device 113 in the external information setting process (step S221) of the timer interrupt process (FIG. 10). The audio lamp control device 113 that has received the first error command controls the error lamp unit 24 and the speaker unit 26 to execute a first error notification that teaches that the first offset process has not been performed normally. Further, the first error command is transmitted to the display control device 214 as it is. The display control device 214 controls the symbol display device 61 to display the content indicating that the first offset processing has not been normally performed as the first error notification. Thereby, the manager of the game hall can recognize that the first offset process of the start-up process is not normally performed in the magnetic sensor module 81 and the magnetic sensor module 81 is not normally activated. The first error notification is executed in the sound lamp control device 113 and the display control device 214 until the above-described activation confirmation command is received. Then, by receiving the activation confirmation command, the error lamp unit 24, the speaker unit 26, and the symbol display device 61 make a notification for teaching that the error has been canceled. In addition, when the first error notification is repeatedly executed, that is, when the first offset process results in an error even if a predetermined measure is taken, the pachinko machine 10 needs to be turned on again.

  That is, the first error notification is started when the first offset processing of the magnetic sensor module 81 results in an error, and the first error notification is ended when the first offset processing is succeeded thereafter. In addition, since the error flag is cleared in step S1004, after the first error command is transmitted once, the first error command is not transmitted again, and the first error notification is already started. The inconvenience of transmitting the first error command is suppressed.

  If “1” is set in the activation confirmation flag in step S1002 and the first offset process of the magnetic sensor module 81 is not an error, or “1” is not set in the error flag in step S1003 and the first If one offset process results in an error but succeeds in the subsequent first offset process, the process proceeds to step S1006. In step S1006, it is determined whether or not “1” is set in the adjusted flag provided in the various flag storage areas 213c of the RAM 213. The adjusted flag is a flag for the MPU 211 to specify that the magnetic sensor module 81 has executed the second offset process. If “1” is set in the adjusted flag, the present sensor correction process is terminated. If “1” is not set in the adjusted flag, an inner frame release signal is confirmed in step S1007 to determine whether or not the inner frame 13 is in an open state. If the sensor is in the open state, the present sensor correction process is terminated.

  If it is determined in step S1007 that the inner frame 13 is in the closed state, a process of setting “100” to the offset counter OT provided in the various counter areas 213d of the RAM 213 is executed in step S1008. The offset counter OT is a counter for the MPU 211 to specify that the magnetic sensor module 81 is in the second offset process, and the timer in step S211 is executed every time the timer interrupt process (FIG. 10) is executed once. This is a counter that is subtracted by 1 in the update process. The numerical information input in step S1008 corresponds to 400 msec, and is set longer than the period (300 msec) required for the magnetic sensor module 81 for the offset process.

  In a succeeding step S1009, a process of setting “1” in the adjusted flag is executed. As a result, the MPU 211 can specify that the second offset process has been executed. In subsequent step S1010, the re-offset flag is confirmed. If “1” is set, it is cleared to “0”, and if it is not set, processing for maintaining the state is executed. In step S1011, the offset signal is set to the HI level signal, and this sensor correction process is terminated. As already described, the second offset process is started on the magnetic sensor module 81 side by specifying the offset signal switching (LOW → HI).

  In step S1001, when the offset signal is being output as the HI level signal, the process proceeds to step S1012. In step S1012, it is determined whether or not the numerical information of the offset counter OT is “0”. If it is not “0”, the sensor correction process is terminated as it is.

  If the numerical information of the offset counter OT is “0”, it is determined whether or not “1” is set in the error flag in step S1013. If “1” is set in the error flag, the error flag is cleared to “0” in step S1014, and the adjusted flag is cleared to “0” in step S1015. Then, in step S1016, processing for setting the re-offset flag to “1” is executed, and in the subsequent step S1017, the second error command is set as a transmission target to the sound lamp control device 113. The second error command is transmitted to the sound lamp control device 113 in the external information setting process (step S221) of the timer interrupt process (FIG. 10). The audio lamp control device 113 that has received the second error command controls the error lamp unit 24 and the speaker unit 26 to execute a second error notification that teaches that the second offset process has not been performed normally. Further, the second error command is transmitted to the display control device 214 as it is. The display control device 214 controls the symbol display device 61 to display a content indicating that the second offset process has not been normally performed as a second error notification. Thereby, the manager of the game hall can recognize that the second offset process has not been performed normally. The second error notification is continuously executed for a predetermined period in the error lamp unit 24, the speaker unit 26, and the symbol display device 61. That is, after the predetermined period has elapsed, the second error notification is not executed unless the second error command is transmitted again. Further, if the second error notification is repeatedly executed, that is, if the second offset process results in an error even if a predetermined measure is taken, the pachinko machine 10 needs to be turned on again.

  Here, in the first error notification based on the reception of the first error command and the second error notification based on the reception of the second error command, the control mode of the error lamp unit 24 and the speaker unit 26 and At least one of the display contents of the symbol display device 61 is set to be different. Specifically, the second error notification is more flashy notification content to attract more attention from the hall manager than the first error notification.

  Although both of the first error notification and the second error notification notify that each offset process of the magnetic sensor module 81 has an error, the first error notification indicates that the magnetic sensor module 81 This corresponds to the first offset process (step S302) automatically performed in the start-up process, and the second error notification is sent to the second offset process (step S404) performed in accordance with an instruction from the main controller 122. This is due to the fact that the conditions that trigger the offset process are different.

  For example, when the power is turned on with the inner frame 13 opened, the first offset process is performed in consideration of the change in magnetism or magnetic field generated from another adjacent pachinko machine 10. It is normal for an error to occur. On the other hand, the second offset process in accordance with the instruction from the main control device 122 is executed with the inner frame 13 closed, so the adjacent pachinko machine 10 is irrelevant, and the second offset process is performed. Is an error based on fraud, such as when strong magnetism is applied from the front. In particular, since the second offset process has one starting condition that the first offset process executed at the time of power-on is successful, the strong magnetism applied from the front is applied at the time of power-on. Although it was not done, the possibility of the above fraud is higher. Therefore, by performing the second error notification rather than the first error notification, the hall manager can quickly cope with the case where the illegal act is performed.

  In addition, when performing these error alerting | reporting, it is good also as a structure which outputs error information to a hall computer via the external terminal board 143. FIG.

  Returning to the description of the sensor correction process (FIG. 21), if the error flag is not set to “1” in step S1013, or after executing the process of step S1017, the offset signal is set to the LOW level in step S1018. The signal is set and the sensor correction process is terminated.

  Therefore, in the pachinko machine 10, when the power is turned on, the magnetic sensor module 81 executes the first offset process in its own startup process (FIG. 11), and then the inner frame 13 is in a closed state as one condition. The second offset process is executed in accordance with an instruction from the main controller 122. As a result, even when the power is turned on with the inner frame 13 opened, the offset process is executed again with the inner frame 13 closed, and the magnetism applied for improper purposes is preferably detected. It is possible to do.

  When the magnetic sensor module 81 is to execute the second offset process, “1” is set to the adjusted flag. If the second offset process results in an error, the adjusted flag is cleared. Therefore, after the second offset process is successful, the offset process is not executed even if the inner frame 13 is opened and closed. If the offset process is executed every time the inner frame 13 is opened / closed, the magnetic sensor 221 is not only deteriorated due to the offset process, but also the offset process is performed during the hall operation. There is concern about fraudulent acts of stealing the eyes of the hall manager and applying magnetism during offset processing. On the other hand, according to the present configuration, it is possible to eliminate these disadvantages.

  As described above, when the magnetic sensor module 81 is configured to execute the offset processing a plurality of times, predetermined processing (the audio lamp control device 113 and the sound lamp control device 113 and the like) is performed on the main control device 122 side based on the success / failure result of the offset processing. In order to execute the process of causing the display control device 214 to execute each error notification, it is necessary to specify the end timing of each offset process and the processing result of the offset process. Therefore, in the present embodiment, the end timing information and the processing result information are specified by using the offset signal transmitted from the main controller 122 in addition to the detection state signal indicating the magnetic detection state. It has a possible configuration.

  Next, the processing of the MPU 211 of the main controller 122 when the detection state flag is set to “1” in the detection state signal reading processing (FIG. 20) will be described with reference to FIG. FIG. 22 is a flowchart showing the magnetic detection process executed in the fraud detection process (step S212) in the timer interrupt process (FIG. 10). In the fraud detection process, in addition to the magnetic detection process, the illegal detection process for detecting an act of erroneously detecting the winning of the game ball by the winning detection sensor 54a or the winning of the game ball using radio waves is performed. It includes radio wave detection processing that detects actions that are attempted to occur fraudulently.

  In the magnetic detection process, first, in step S1101, it is determined whether or not the magnetic sensor module 81 is in a magnetic detection state by confirming whether or not “1” is set in the detection state flag. If the magnetic sensor module 81 is not in the magnetic detection state, the magnetic detection counter provided in the various counter areas 213d of the RAM 213 is cleared to “0” in step S1102, and the magnetic detection process is terminated. The magnetic detection counter is a counter that indicates the number of times the MPU 211 has specified that the magnetic sensor module 81 has entered the magnetic detection state.

  If the magnetic sensor module 81 is in the magnetic detection state, in the subsequent step S1003, a process of adding 1 to the magnetic detection counter is executed. In a succeeding step S1004, it is determined whether or not the numerical information after the addition is “2”. That is, it is determined whether or not the MPU 211 on the main controller 122 side confirms that the magnetic sensor module 81 is in a magnetic detection state a plurality of times. If the numerical information of the magnetism detection counter is not “2”, the magnetism detection process is terminated as it is.

  If an affirmative determination is made in step S1004, the magnetic detection command is set as a transmission target to the audio lamp control device 113 in step S1005. The magnetic detection command is a command for causing the audio lamp control device 113, which is the sub-side control device, to recognize that the MPU 211 has identified the occurrence of an illegal act of applying magnetism. The magnetic detection command is transmitted to the sound lamp control device 113 in the external information setting process (step S221) in the timer interrupt process (FIG. 10).

  The voice lamp control device 113 that has received the magnetism detection command performs notification through the error lamp unit 24 and the speaker unit 26 in response to the specification of the fraud that applies magnetism. In addition, a notification-type command corresponding to reception of the magnetic detection command is transmitted to the display control device 214. The display control device 214 performs notification corresponding to the identification of fraud using a magnet through the symbol display device 61. As a result, the hall manager can specify the fraud.

  After executing the process of step S1105, the process proceeds to step S1106. In step S1106, an abnormal external output start process is executed in order for the gaming hall management computer to recognize that the occurrence of an illegal act of applying magnetism has been identified. The output setting for the external terminal board 143 is executed in the external information setting process (step S221) of the timer interrupt process (FIG. 10). After executing the process of step S1106, the magnetic detection process is terminated.

  Therefore, in this pachinko machine 10, in addition to the configuration in which the magnetic sensor module 81 performs the magnetic confirmation process a plurality of times, the main controller 122 also performs the confirmation process a plurality of times. Magnetic false detection can be suppressed.

  Next, the timing at which the magnetic sensor module 81 executes the offset process will be described with reference to FIG. FIG. 23 is a timing chart for explaining the execution timing of the offset process of the magnetic sensor module 81 from the relationship between the power supply of the pachinko machine 10 and the state of the inner frame 13. 23 (b) shows the power supply state of the pachinko machine 10, FIG. 23 (c) shows how the magnetic sensor module 81 performs the offset process, and FIG. 23 (d) shows the RAM 213. FIG. 23 (e) shows the error flag of the RAM 213, FIG. 23 (f) shows the adjusted flag of the RAM 213, FIG. 23 (g) shows the re-offset flag of the RAM 213, and FIG. h) shows the state of the offset signal from the main controller 122, and FIG. 23 (i) shows the state of the detection state signal from the magnetic sensor module 81.

  First, a case will be described in which both the first offset process in the magnetic sensor module 81 and the second offset process based on an instruction from the main controller 122 have been successfully executed.

  When the power of the pachinko machine 10 is turned on at the timing t1, in the magnetic sensor module 81, as shown in FIG. 23C, the first offset process is executed by the startup process (FIG. 11). As already described, the first offset process is not executed by an instruction from the main controller 122 but is automatically executed by the process of the magnetic sensor module 81 itself. Therefore, as shown in FIG. 23 (h), the offset signal output from the main controller 122 remains the LOW level signal.

  When the first offset process is completed at the timing t2 and the first offset process is successful (step S303: YES), on the main controller 122 side, the detection state signal is a LOW level signal. Then, as shown in FIG. 23 (d), “1” is set in the activation confirmation flag (step S804). On the magnetic sensor module 81 side, the start-up process (FIG. 11) is terminated and the normal process (FIG. 15) is started and the magnetic detection process (step S501) and the like are executed due to the success of the offset process. Is possible. However, since the first offset process executed at the timing of t1 is executed with the inner frame 13 opened, the change in magnetism or magnetic field generated from another pachinko machine 10 provided adjacent to the first frame is detected. There is a high possibility that the adjustment has been taken into account.

  Therefore, when the inner frame 13 is closed at the timing t3, on the main controller 122 side, the offset signal is switched from the LOW level signal to the HI level signal as shown in FIG. In this case, as shown in FIG. 23F, “1” is set in the adjusted flag. When the offset signal is switched from the LOW level signal to the HI level signal (step S503: YES), the magnetic sensor module 81 executes the second offset process as shown in FIG. 21C (step S507). ).

  When the second offset process ends at the timing t4 and the second offset process is successful (step S706: YES), the detection state signal is set to the LOW level signal on the magnetic sensor module 81 side ( Step S708). On the main controller 122 side, the timer interrupt process (FIG. 10) has already been executed periodically, and the second offset process is completed when the numerical information of the offset counter OT is “0” at the timing t5. It becomes possible to specify what has been done. In this case, since the error flag remains “0” as shown in FIG. 23E, the adjusted flag is not cleared and the offset signal is switched to the LOW level signal. Further, as shown in FIG. 23G, the re-offset flag remains “0”.

  Thereafter, even if the inner frame 13 is opened at the timing of t6 and closed at the timing of t7, since the adjusted flag is already set to “1”, the offset signal is not switched again, and the magnetic sensor Module 81 does not perform offset processing.

  When magnetism is applied at the timing of t8, as shown in FIG. 23 (i), the detection state signal is switched to the HI level signal on the magnetic sensor module 81 side, and on the main controller 122 side, The start confirmation flag is set to “1” (step S905: YES), the offset signal is output as a LOW level signal (step S906), and the reset flag is not set to “1”. (Step S908: NO), the detection state flag is set to “1”, and the processing when the magnetic sensor module 81 is in the magnetic detection state in the magnetic detection processing (FIG. 22) is executed. .

  Next, a case where the first offset process in the startup process of the magnetic sensor module 81 results in an error will be described.

  When the power of the pachinko machine 10 is turned on at the timing t9, the first offset processing is started in the magnetic sensor module 81 as described above. For example, when strong magnetism is detected in the offset processing, when the first offset processing ends at the timing of t10, the detection state signal is switched to the HI level signal as shown in FIG. In this case, on the main controller 122 side, “1” is set in the error flag in the sensor confirmation process (FIG. 19) (step S805). In the main controller 122, the sensor confirmation process (FIG. 17) and the main process (FIG. 9) can be ended, the timer interrupt process (10) is started, and other control can be executed. Then, since “1” is not set in the activation confirmation flag and “1” is set in the error flag, in the sensor correction process (FIG. 19) of the timer interrupt process executed at the timing of t11. The first error command is set (step S1005), and the first error notification is executed by the sound lamp control device 113 and the display control device 214. As a result, the hall manager can recognize the error, and can take measures such as removing the strong magnetism that caused the error. Further, when setting the first error command, the error flag is cleared to “0”. Therefore, a plurality of first error commands are not transmitted for one error.

  Since the first offset process started at the timing t9 is an error, in the magnetic sensor module 81, the first offset process is started again at the timing t12 in the start-up process (FIG. 11). Since the magnetic sensor module 81 also executes the first offset processing this time regardless of an instruction from the main controller 122, the offset signal output from the main controller 122 remains the LOW signal. In the figure, the end timing of the first offset process at the timing of t10 and the start timing of the first offset process at the timing of t12 are shown separately for easy understanding. However, in actuality, the first offset process is illustrated at the timing of t10. When the offset process becomes an error, the first offset process is started again continuously.

  If, for example, the inner frame 13 is closed (see FIG. 23A) at the timing of t13 during the first offset process, the fluctuation width of the detected value in the magnetic sensor module 81 becomes large, and the offset process is performed again. An error occurs. Therefore, even if the offset process ends at the timing t14, the detection state signal remains the HI level signal. On the main controller 122 side, even if the detection state signal is an HI level signal, “1” is not set in the activation confirmation flag, so the error flag remains “0” and the detection state flag is also “0”. "".

  Since the first offset process started at the timing t12 is an error again, the first offset process is further started at the timing t15. Also in this case, the offset signal output from the main controller 122 remains the LOW signal. Similarly to the above, in the drawing, the end timing of the first offset process at the timing t14 and the start timing of the first offset process at the timing t15 are shown separately for easy understanding.

  When the first offset process ends at the timing of t16 and the first offset process is successful, the detection state signal from the magnetic sensor module 81 is switched to the LOW level signal. In this case, “1” is set to the activation confirmation flag on the main control device 122 side.

  In the sensor correction process executed at the timing of t17, “1” is set to the adjusted flag, and the offset signal is switched from the LOW level signal to the HI level signal. As a result, the second offset process is executed on the magnetic sensor module 81 side by switching the offset signal.

  When the second offset process is completed at the timing t18 and the second offset process is successful, the numerical information of the offset counter OT is “0” at the timing t19 on the main controller 122 side as described above. ", It can be determined that the second offset processing has been completed, and the error flag is" 0 ", the processing result of the second offset processing can be specified, and the offset signal is at the LOW level. Switch to signal.

  Next, a case where the second offset process based on an instruction from the main control device 122 has an error will be described. In the following description, a description will be given from a situation in which the power of the pachinko machine 10 is already ON, timer interrupt processing is started on the main controller 122 side, and normal processing is started on the magnetic sensor module 81 side.

  When the inner frame 13 is closed at the timing t20, the offset signal from the main controller 122 is switched from the LOW level signal to the HI level signal. Then, based on the switching of the offset signal, the second offset process is started on the magnetic sensor module 81 side.

  For example, when an improper act of applying strong magnetism is performed in the offset process, the detection state signal is switched to the HI level signal when the offset process ends at the timing t21. In this case, the detection state signal is the HI level signal (step S901: YES), the activation confirmation flag is set to “1” (step S905: YES), and the offset signal is being output as the HI level signal ( Step S906: YES), “1” is set in the error flag (Step S907).

  In the sensor correction process executed at the timing t22 when the numerical information of the offset counter OT becomes “0”, the error flag and the adjusted flag are cleared (step S1014, step S1015), as shown in FIG. The re-offset flag is set to “1” (step S1016). Further, the second error command is set (step S1017), and the second error notification is executed by the sound lamp control device 113 and the display control device 214. As a result, the hall manager can recognize the fraud and can take appropriate measures against the fraud. Then, the offset signal is switched to the LOW level signal.

  At the timing t23, which is the next sensor correction process, “1” is set in the adjusted flag, and the re-offset flag is cleared. Then, the offset signal is switched from the LOW level signal to the HI level signal. As a result, the magnetic sensor module 81 starts the second offset process again. When the second offset process ends at the timing t24 and the second offset process is successful, the detection state signal from the magnetic sensor module 81 is switched to the LOW level signal. Then, when the numerical information of the offset counter OT becomes “0” at the timing of t25, the offset signal from the main controller 122 is switched to the LOW level signal.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The magnetic sensor module 81 is configured to execute the second offset process when the inner frame 13 is in a closed state at a timing after the initial drive on the main controller 122 side is completed after the power is turned on. As a result, it is possible to detect the surrounding magnetism with a detection value that does not take into account the change in the magnetic field that occurs when the pachinko machine 10 is turned on, or the magnetism generated by the initial drive test of each control device accompanying the power on. Become.

  In general, the pachinko machine 10 is installed in parallel with the Hall Island facility, and when the plurality of installed pachinko machines 10 are in a state in which the inner frame 13 is opened, the inner frame in one pachinko machine 10 is provided. The back surface of the inner frame 13 of the other pachinko machine 10 is arranged in front of 13. That is, when the offset process is executed with the inner frame 13 opened, the magnetic sensor module 81 of one pachinko machine 10 also generates magnetism generated from each control device provided in the inner frame 13 of the other pachinko machine 10. In consideration of this, the detected value will be calibrated. These magnetisms cannot be detected when the pachinko machine 10 is normally driven. Therefore, by making the execution condition of the second offset process that the inner frame 13 is in the closed state, it is possible to calibrate the detection value without taking into account the magnetism that cannot be normally detected.

  Here, in the configuration in which the offset process is executed in a situation where the inner frame 13 is in the closed state after the power is turned on as described above, a configuration in which the offset process is executed only in the situation may be adopted. Such a configuration seems to be preferable from the viewpoint of simplifying the configuration of the magnetic sensor module 81. However, with this configuration, for example, a fraudulent jig is attached to the inner frame opening switch 13a so that the main control device 122 determines that the inner frame 13 is in an open state and prevents the magnetic sensor module 81 from performing an offset process. There is concern about cheating. Compared with the magnetism generated when the power is turned on and the magnetism from other pachinko machines 10, the improperly applied magnetism can be said to be strong magnetism because it is a magnetism that can guide the game ball to the opening. Therefore, in this embodiment, the configuration is such that the offset process is automatically executed to calculate a temporary calibration value when the power is turned on. It becomes possible to suppress the act.

  The magnetic sensor module 81 is configured to be in a magnetic detection state when magnetism is applied from the front. Specifically, the direction filter process (step S502) for specifying the direction of the magnetism applied in the magnetism detection process (FIG. 15) is executed, and only the magnetism applied from the front to the magnetic sensor 221 is extracted. To be detected. The magnetic sensor module 81 is provided in the game board 50, and the improperly applied magnetism is assumed to be applied from the front of the game board 50. On the back of the game board 50, various drive units and various kinds are provided. A control device is provided. Therefore, it is possible to set only the magnetism applied illegally without setting the magnetism based on these various drive units and various control devices as the detection target.

  The magnetic sensor module 81 is configured to execute a magnetic detection process periodically (20 msec) and to enter a magnetic detection state when magnetism is detected over a plurality of times (three times). Since it is assumed that the magnetism generated in the various drive units of the pachinko machine 10 converges in a period shorter than the period of the magnetism detection process, even if it is detected in one process of the magnetism detection process, It is not detected in the processing times. Furthermore, the game ball launching mechanism 40 of the various drive units is configured such that a game ball is launched by periodically launching a launch solenoid or a ball feeder, and the period of the magnetic detection process is the launch solenoid. Or shorter than the cycle of the ball feeder, and the cycle does not synchronize a plurality of times. Thereby, it becomes possible to make only the magnetism improperly applied to the detection object without making the magnetism generated by these launching solenoids and the ball feeding device the detection object.

  The processing result of the second offset processing executed by the magnetic sensor module 81 is configured to be transmitted to the main control device 122 side using the detection state signal. As described above, when the second offset process is executed after the initial drive on the main controller 122 side, the second offset process is performed while the main controller 122 is in the normal drive state, that is, the timer interrupt process is started. It will be. That is, in order to execute a predetermined process (second error notification) based on the process result of the second offset process, it is necessary to receive the process result within the timer interrupt process. On the other hand, it is not preferable that the number of transmission / reception terminals and connection lines increase extremely. Therefore, by adopting a configuration in which the processing result information and the magnetic detection state information are output as the same signal, it is possible to execute a predetermined process based on the processing result while simplifying the configuration. Become.

  In this case, there is a concern about the confusion between the processing result information and the magnetic detection state information on the main controller 122 side. Therefore, in the present embodiment, the information on the processing result and the information on the magnetic detection state are distinguished from the information on the output mode of the offset signal used for causing the magnetic sensor module 81 to execute the second offset processing. It is possible. Therefore, the use of the output signal (offset signal) used to achieve each of the effects described above is used to distinguish the information on the processing result from the information on the magnetic detection state. Confusion.

  Each offset process is configured to be executed over a predetermined period, and when magnetism exceeding a predetermined reference value is detected in the period, each offset process becomes an error and a corresponding error notification is executed. Each offset process is a process of calibrating the magnetism around the magnetic sensor module 81 as 0 value, whereas the improperly applied magnetism is assumed to have a magnetic intensity that induces a game ball, for example. If magnetism is improperly applied during the offset process, there is a high possibility that the offset process will cause an error. When the offset process results in an error, error notification is executed as described above. Therefore, even in a period in which each offset process is executed, it can be said that the magnetism applied improperly is monitored, and the improperly applied magnetism can be suitably detected.

  The magnetic sensor module 81 has a configuration in which, after the second offset process is performed in a state where the inner frame 13 is in the closed state, the second offset process is not performed even if the opening / closing operation of the inner frame 13 is performed thereafter. Although it is in the state where the improperly applied magnetism is monitored during each offset process as described above, it is not a period during which the regular magnetism detection process (FIG. 16) is performed. Therefore, the number of offset processes can be reduced, and the period during which the magnetism detection process is executed can be lengthened to appropriately detect improperly applied magnetism.

  The MPU 222 includes a magnetic sensor 221 and an MPU 222, and the MPU 222 executes each process based on detection information of the magnetic sensor 221. Therefore, it is possible to reduce the processing load of the main control device 122 as compared with the configuration in which the main control device 122 executes each process based on the detection information of the magnetic detection sensor.

<Second Embodiment>
In this embodiment, the structure which transmits the process result of each offset process of the magnetic sensor module 81 differs from the said 1st Embodiment. Hereinafter, different configurations will be described with reference to FIGS.

  In the first embodiment, the processing result of each offset processing is transmitted using the detection state signal. However, in the present embodiment, transmission is performed using another output terminal provided in the magnetic sensor module 81. The configuration is as follows. Specifically, the magnetic sensor module 81 is provided with an output terminal for outputting the success / failure result of each offset process, in addition to the output terminal for outputting the detection state signal, and the output terminal is also provided as the main control board. 201 is electrically connected. Then, an offset success signal and an error signal are transmitted from the output terminal as a success / failure signal indicating the success / failure result of each offset process. Each of the successful offset signal and the error signal is a pulse signal configured by repeating switching between the LOW level signal and the HI level signal in a short time, and any success or failure can be achieved by changing the period of the pulse signal. Whether it is a signal can be specified.

  First, processing on the magnetic sensor module 81 side in the present embodiment will be described. FIG. 24 is a flowchart showing start-up processing in the present embodiment.

  In the start-up process in the present embodiment, the terminal reading process, the first offset process, and the success / failure results of the first offset process in steps S1201 to S1203, as in steps S301 to S303 in the first embodiment. Execute the process of determining. If it is determined in step S1203 that the first offset process has succeeded, in step S1204, the successful offset signal is transmitted to the main controller 122, and the start-up process is terminated. To do.

  If the first offset process is an error in step S1203, the process proceeds to step S1205, and the error signal of the success / failure signals is transmitted to the main controller 122. In step S1206, the RAM 224 is cleared, the process returns to step S1203, and the first offset process is executed again.

  Although not shown, in the second offset process (FIG. 17) of the normal process in the present embodiment, the offset success signal is transmitted in step S708, and the error signal is transmitted in step S709.

  Next, processing on the main control device 122 side will be described. FIG. 25 is a flowchart showing sensor confirmation processing in the present embodiment.

  In the sensor confirmation process in the present embodiment, a detection sensitivity setting signal is transmitted in step S1301, similarly to the process in step S801 in the first embodiment. In the subsequent step S1302, it is determined whether or not an offset success signal or an error signal has been received as the success / failure signal. If no success / failure signal is received, the process waits as it is. Therefore, in step S1302, the process waits until the first offset process of the magnetic sensor module 81 is completed once.

  By making an affirmative determination in step S1302, the process proceeds to step S1303. In step S1303, a process of setting “1” to the success / failure reception flag provided in the various flag storage areas 213c of the RAM 213 is executed. The success / failure reception flag is a flag for the MPU 211 to specify that the success / failure signal of the offset success signal and the error signal has been received.

  In subsequent step S1304, it is determined whether or not the signal is an error signal by confirming the cycle of the signal received in step S1302. If the success / failure signal from the magnetic sensor module 81 is an error signal, it means that the first offset processing has not been normally executed in the magnetic sensor module 81. In this case, in step S1305, processing for setting “1” in the error flag of the RAM 213 is executed.

  When a negative determination is made in step S1304, or after the process of step S1305 is executed, the sensor confirmation process is terminated.

  Next, the success / failure signal read process executed in the read process (step S209) of the timer interrupt process (FIG. 10) will be described with reference to the flowchart of FIG.

  First, in step S1401, it is determined whether an offset success signal or an error signal is received as a success / failure signal from the magnetic sensor module 81. If no signal is received, the success / failure signal reading process is terminated.

  If any signal is received, the success / failure reception flag is confirmed in the subsequent step S1402. If "1" is set, the state is maintained, and if not set, "1" is maintained. ”Is set. In a succeeding step S1403, it is determined whether or not the success / failure signal received in the step S1401 is an error signal. If it is not an error signal, the error flag is checked in step S1404. If “1” is set, a process of clearing it to “0” is executed. If it is not set, the state is maintained. Then, the success / failure signal reading process is terminated. On the other hand, if it is an error signal in step S1403, the error flag is confirmed in step S1405. If “1” is set, the state is maintained, and if it is not set, “ 1 "is executed, and the success / failure signal reading process is terminated.

  Therefore, in the success / failure signal reading process, when the successful offset signal is received, the success / failure reception flag is set to “1”, the error flag is cleared to “0”, and when the error signal is received, While the success / failure reception flag is set to “1”, the error flag is also set to “1”. Thereby, when the magnetic sensor module 81 performs the offset process, the MPU 211 of the main control device 122 can specify that the offset process is completed and the success / failure result of the offset process.

  Although not shown, in the detection state signal reading process in the present embodiment, the detection result signal of the HI level signal is read because the offset processing result is output as a success / failure signal as described above. As a condition, “1” is set to the detection state flag without performing other processing.

  Next, sensor correction processing in the present embodiment will be described with reference to the flowchart of FIG.

  In the sensor correction process in the present embodiment, first, in step S1501, it is determined whether or not the offset signal is output as a HI level signal, as in the process in step S1001 of the first embodiment. If the offset signal is not a HI level signal, it is determined in subsequent step S1502 whether the last received success / failure signal is an error signal. Specifically, by determining whether the success / failure reception flag is set to “1” and the error flag is also set to “1”, the offset success signal is not received after the error signal. Can be identified. In this case, the first offset process of the magnetic sensor module 81 is in an error state, and in the subsequent step S1503, the first error command is set as a transmission target to the sound lamp control device 113. By setting the first error command, the first error notification is executed by the error lamp unit 24, the speaker unit 26, and the symbol display device 61 as in the first embodiment. However, the first error notification in the present embodiment is configured to end when the error lamp unit 24, the speaker unit 26, and the symbol display device 61 are executed for a predetermined period.

  After executing the process of step S1503, in step S1504, a process of clearing the success / failure reception flag to “0” is executed, and this sensor correction process is terminated.

  If a negative determination is made in step S1502, that is, if at least one of the success / failure reception flag and the error flag is “0”, the process proceeds to step S1505 to determine whether or not “1” is set in the error flag. The case where “1” is set in the error flag in step S1505 is a case where the first offset processing has failed and the processing in steps S1503 and S1504 has already been executed in the previous processing round. In this case, the present sensor correction process is terminated as it is.

  If “1” is not set in the error flag in step S1505, that is, if the first offset process is successful in the magnetic sensor module 81, the success / failure reception flag is confirmed in step S1506. When it is “0”, the state is maintained, and when “1” is set, a process of clearing to “0” is executed.

  In a succeeding step S1507, it is determined whether or not “1” is set to the adjusted flag provided in the various flag storage areas 213c of the RAM 213. If “1” is set in the adjusted flag, the present sensor correction process is terminated. If “1” is not set in the adjusted flag, an inner frame release signal is confirmed in step S1508, and it is determined whether or not the inner frame 13 is in an open state. If the sensor is in the open state, the present sensor correction process is terminated.

  If it is determined in step S1508 that the inner frame 13 is in the closed state, the offset signal is set to the HI level state in step S1509, and this sensor correction process is terminated.

  If an affirmative determination is made in step S1501, that is, if the offset signal is being output as a HI level signal, the process proceeds to step S1510. In step S1510, it is determined whether or not “1” is set in the success / failure reception flag. If “1” is not set in the success / failure reception flag, the present sensor correction process is terminated as it is.

  If “1” is set in the success / failure reception flag in step S1510, it means that the second offset process has been completed on the magnetic sensor module side, and in this case, the process proceeds to step S1511. In step S1511, it is determined whether or not the above-described offset processing has succeeded by determining whether or not “1” is set in the error flag. If the second offset process is an error (step S1511: YES), the second error command is set as a transmission target to the sound lamp control device 113 in step S1512. By setting the second error command, the second error notification is executed by the error lamp unit 24, the speaker unit 26, and the symbol display device 61 as in the first embodiment.

  After executing the process of step S1512 or step S1513, the process proceeds to step S1514, and a process of clearing the success / failure reception flag and the error flag to “0” is executed. Thereafter, in step S1515, the offset signal is set to a LOW level signal, and this sensor correction process is terminated.

  Next, the timing at which the magnetic sensor module 81 performs the offset process in the present embodiment will be described with reference to FIG. FIG. 28 is a timing chart for explaining the execution timing of the offset processing of the magnetic sensor module 81 from the relationship between the power supply of the pachinko machine 10 and the state of the inner frame 13. 28 (b) shows the power supply state of the pachinko machine 10, FIG. 28 (c) shows how the magnetic sensor module 81 executes the offset process, and FIG. 28 (d) shows the RAM 213. FIG. 28 (e) shows the error flag of the RAM 213, FIG. 28 (f) shows the adjusted flag of the RAM 213, and FIG. 28 (g) shows the state of the offset signal from the main control board 201. Show.

  First, a case will be described in which both the first offset process in the magnetic sensor module 81 and the second offset process based on an instruction from the main controller 122 have been successfully executed.

  When the power of the pachinko machine 10 is turned on at the timing t1, as shown in FIG. 28 (c), the magnetic sensor module 81 executes the first offset process. As already described, the offset process is not executed by an instruction from the main controller 122, but is automatically executed by the magnetic sensor module 81 itself. Therefore, as shown in FIG. 28 (g), the offset signal output from the main controller 122 remains the LOW level signal.

  When the first offset process ends at the timing t2, and the first offset process is successful, the magnetic sensor module 81 transmits an offset success signal as a success / failure signal (step S1204). On the main control device 122 side, as shown in FIG. 28 (d), “1” is set to the success / failure reception flag based on the reception of the offset success signal (step S1303). On the magnetic sensor module 81 side, when the first offset process is successful, the start-up process (FIG. 24) is terminated, and the normal process is started, so that the magnetic detection process and the like can be executed. However, also in the present embodiment, the first offset process executed at the timing t1 is executed with the inner frame 13 opened, and thus occurs from another pachinko machine 10 provided adjacently. There is a high possibility that the adjustment takes account of changes in magnetism and magnetic field.

  Therefore, when the inner frame 13 is closed at the timing of t3, on the main controller 122 side, as shown in FIG. 28 (d), the success / failure reception flag is cleared to “0”, and FIG. As shown in g), the offset signal is switched from the LOW level signal to the HI level signal. As a result, in the magnetic sensor module 81, the second offset process is executed as shown in FIG. 28C by switching the offset signal.

  When the second offset process ends at the timing t4 and the second offset process is successful, the magnetic sensor module 81 transmits an offset success signal as a success / failure signal. On the main controller 122 side, the timer interrupt process (FIG. 10) has already been executed periodically, and the success / failure reception flag is set in the success / failure signal read process (FIG. 26) based on the reception of the offset success signal. “1” is set (step S1402). Thereafter, at the timing of t5, as shown in FIG. 28 (f), the adjusted flag is set to “1” (step S1513), and the success / failure reception flag is cleared to “0” (step S1514). Then, as shown in FIG. 28 (g), the offset signal is switched to the LOW level signal (step S1515).

  Thereafter, even if the inner frame 13 is opened at the timing of t6 and closed at the timing of t7, since the adjusted flag is already set to “1”, the offset signal is not switched again, and the magnetic sensor Module 81 does not perform offset processing.

  Next, a case where the offset process in the startup process of the magnetic sensor module 81 results in an error will be described.

  When the power of the pachinko machine 10 is turned on at timing t8, the first offset process is started in the same manner as described above. For example, when strong magnetism is detected in the first offset processing, an error signal is transmitted when the first offset processing ends at the timing t9. In this case, on the main controller 122 side, “1” is set to the success / failure reception flag, and “1” is also set to the error flag as shown in FIG. On the main control device 122 side, the sensor confirmation processing (FIG. 25) can be ended after these flags are set, and the timer interrupt processing (10) is started so that other control can be executed. Since “1” is set in the success / failure reception flag and the error flag, the first error command is set (step S1503) in the sensor correction process (FIG. 27) executed at the timing t10. The first error notification is executed by the lamp control device 113 and the display control device 214. As a result, the hall manager can recognize the error, and can take measures such as removing the strong magnetism that caused the error. When the first error command is set, the success / failure reception flag is cleared to “0”. Therefore, a plurality of first error commands are not transmitted for one error.

  Since the first offset process started at the timing t8 is an error, the first offset process is started again at the timing t11. The first offset processing in this case is also executed by the magnetic sensor module 81 regardless of an instruction from the main control device 122, so that the offset signal output from the main control device 122 remains the LOW signal (FIG. 28 (g )reference). In the present embodiment, when the first offset process is an error, the first offset process is continuously started again. However, in the drawing, for the sake of easy understanding, the first offset process is ended. The timing and the start timing of the first offset process are described separately.

  If, for example, the inner frame 13 is closed (see FIG. 28A) at the timing t12 during the first offset process, the fluctuation width of the detected value in the magnetic sensor module 81 becomes large, and the first offset process is performed. Again becomes an error. Then, when the first offset process ends at the timing of t13, an error signal is transmitted. Since the timer interrupt process has already been started on the main controller 122 side, the offset success signal is read in the success / failure signal read process (FIG. 26). In this case, as shown in FIGS. 28D and 28E, the success / failure reception flag is set to “1”, and the error flag is maintained in a state where “1” is set. Then, at the timing t14, the first error command is set again, and the first error notification is executed. In this case, the success / failure reception flag is cleared to “0”.

  Since the first offset process started at the timing t11 is an error again, the first offset process is further started at the timing t15. Also in this case, the offset signal output from the main controller 122 remains the LOW signal (see FIG. 28 (g)). Similarly to the above, in the figure, for easy understanding, the end timing of the first offset process and the start timing of the first offset process are described separately.

  When the first offset process ends at the timing of t16 and the first offset process is successful, the magnetic sensor module 81 transmits an offset success signal. In this case, on the main controller 122 side, as shown in FIGS. 28D and 28E, the success / failure reception flag is set to “1” and the error flag is cleared to “0”.

  At time t17, the success / failure reception flag is cleared to “0”, and the offset signal is switched from the LOW level signal to the HI level signal. As a result, on the magnetic sensor module 81 side, the second offset process is started by switching the offset signal.

  When the second offset process ends at the timing of t18 and the second offset process is successful, “1” is set to the success / failure reception flag on the main control device 122 side as described above. At the timing t19, the adjusted flag is set to “1”, the success / failure reception flag is cleared to “0”, and the offset signal is switched to the LOW level signal.

  Next, a case where an offset process based on an instruction from the main controller 122 side results in an error will be described. In the following description, a description will be given from a situation in which the power of the pachinko machine 10 is already ON, timer interrupt processing is started on the main controller 122 side, and normal processing is started on the magnetic sensor module 81 side.

  When the inner frame 13 is closed at the timing t20, the offset signal from the main controller 122 is switched from the LOW level signal to the HI level signal. Then, based on the switching of the offset signal, offset processing is started on the magnetic sensor module 81 side.

  For example, in the offset process, when an illegal act of applying strong magnetism is performed, an error signal is transmitted when the offset process ends at the timing t21. In this case, on the main controller 122 side, “1” is set to the success / failure reception flag, and “1” is also set to the error flag.

Since the offset signal is being output as the HI level signal (step S1501: YES) and the success / failure reception flag and the error flag are set to “1”, the sensor correction process executed at the timing t22 (FIG. 25). ), The second error command is set (step S1512), and the second error notification is executed by the sound lamp control device 113 and the display control device 214. As a result, the hall manager can recognize the fraud and can take appropriate measures against the fraud. In this case, the success / failure reception flag is cleared to “0” (step S1514). Therefore, a plurality of second error commands are not transmitted for one error. Further, the error flag is cleared to “0” and the offset signal is switched to the LOW level signal. Therefore, it is possible to execute processing for causing the magnetic sensor module 81 to perform offset processing in the next sensor correction processing (step S1501: YES, step S1505: YES).
When the offset signal is switched from the LOW level signal to the HI level signal again at the timing of t23, the magnetic sensor module 81 starts the second offset process again. When the second offset process is completed at the timing t24 and the second offset process is successful, the magnetic sensor module 81 transmits an offset success signal. On the main controller 122 side, the success / failure reception flag is set to “1”, and the error flag is cleared to “0”.

  Then, in the sensor correction process executed at the timing of t25, “1” is set to the adjusted flag, and the offset signal is switched to the LOW level signal.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  When the processing result of each offset process in the magnetic sensor module 81 is transmitted, the processing result is transmitted by a success / failure signal provided separately from the detection state signal indicating the magnetic detection state information. Thereby, even while the second offset process is being executed in accordance with an instruction from the main control device 122 side, it is possible to detect an illegal act in which magnetism is applied to the pachinko machine 10 by the magnetic detection process. Therefore, it is possible to suitably detect the magnetism applied by the illegal act.

  In particular, in the present embodiment, since it is configured to separately transmit as a success / failure signal, not only the processing result of each offset process but also the end timing of each offset process can be specified on the main controller 122 side. Yes. In the first embodiment, the end timing is specified by using the timer counter (offset counter OT). However, the main control device 122 is controlled by the difference in processing timing between the main control device 122 and the magnetic sensor module 81. There is a case where the specified end timing and the timing at which the offset process is actually ended may be different from each other. In order to suppress malfunction due to the deviation, the timer counter on the main control device 122 side is longer than the processing period of the actual offset process. It was configured to count for a long time. On the other hand, according to the present embodiment, the success / failure signal is transmitted at the actual end timing of the offset processing, and the main control device 122 can specify the end timing by receiving the success / failure signal. Therefore, it is possible to specify the timing closer to the actual end timing. Thereby, the process (each error notification) according to the process result of the offset process can be quickly executed, and the hall manager can be recognized early.

<Third Embodiment>
In the present embodiment, the timing for executing the offset process of the magnetic sensor module 81 is different from those in the first and second embodiments. Hereinafter, a different configuration will be described with reference to FIG. FIG. 29 is a flowchart showing the sensor confirmation processing in the present embodiment. In the following description, only the differences will be described based on the first embodiment.

  First, in the present embodiment, the magnetic sensor module 81 is configured not to execute the first offset process in the start-up process. That is, only the second offset process is executed without executing the first offset process. Further, since the first offset process is not executed, the detection state signal reading process (FIG. 20) in the present embodiment is configured to end the process as it is when a negative determination is made in step S901. Further, in the sensor correction process (FIG. 21) in the present embodiment, if a negative determination is made in step S1001, the process proceeds to step S1006.

  In the sensor confirmation process in the present embodiment, first, a detection sensitivity setting signal is transmitted in step S1601, and in the subsequent step S1602, it is determined whether or not the inner frame 13 is in an open state. When the inner frame 13 is in the open state, the present sensor confirmation process is terminated as it is. In this case, in the sensor correction process (FIG. 21), 1 is not set in the adjusted flag (step S1006: NO), and the inner frame 13 is in the closed state (step S1007: NO). Perform offset processing. If the inner frame 13 is in the closed state in step S1602, the first standby process is executed in step S1603. The first standby process is a process that waits while the initial drive test of each control device is executed based on the power-on setting process in step S109 of the main process (FIG. 10), and specifically waits for 10 seconds. After the processing in step S1603, the offset signal is switched from the LOW level signal to the HI level signal in step S1604.

  In a succeeding step S1605, a second standby process is executed. The second standby process corresponds to the process of step S802 in the first embodiment. The processing from step S1606 to step S1608 is the same as the processing from step S803 to step S805 in the first embodiment. However, in step S1607, a process of setting “1” in the adjusted flag is executed. After executing the process of step S1607 or step S1608, the sensor confirmation process is terminated.

  That is, in the present embodiment, when the power of the pachinko machine 10 is turned on with the inner frame 13 opened, the magnetic sensor module 81 executes an offset process at the timing when the inner frame 13 is closed. When the power of the pachinko machine 10 is turned on with the frame 13 closed, the magnetic sensor module 81 is configured to execute an offset process after the initial drive test of each control device.

  According to the present embodiment described in detail above, the number of times that the magnetic sensor module 81 performs the offset process can be reduced. As already described, since the normal magnetic detection process is not performed during the offset process, it is possible to substantially extend the period during which the magnetic detection process can be performed by reducing the number of offset processes. . Thereby, the improperly applied magnetism can be suitably detected.

  However, in the case of the present embodiment, it is not possible to suppress an illegal act that does not execute the offset process of the magnetic sensor module 81 by always turning the inner frame opening switch 13a to the OFF state (open state) by an unauthorized jig. Therefore, in the case of the present embodiment, it is desirable to take a predetermined measure so as to suppress an illegal act against the inner frame opening switch 13a. As a predetermined countermeasure, for example, a physical countermeasure such as providing a shielding portion that makes it difficult or impossible to insert an unauthorized jig, and the main controller 122 and the magnetic sensor module 81 are confident that the inner frame 13 is opened or closed ( A software measure that makes it possible to determine (position) can be considered.

<Fourth Embodiment>
In the present embodiment, the configuration relating to the detection value when the magnetic sensor module 81 detects magnetism is different from those of the first to third embodiments. Hereinafter, different configurations will be described.

  As described above, in the first to third embodiments, the sensitivity level is determined by the threshold value as the amount of change from the zero value required to enter the magnetic detection state. In contrast, in the present embodiment, the sensitivity level is set by a function of amplifying (changing the amplitude) the magnetic detection value (impedance change amount) in the magnetic sensor 221.

  First, the magnetic sensor 221 of the magnetic sensor module 81 will be described in detail with reference to the block diagram of FIG.

  The magnetic sensor 221 according to the present embodiment includes a sensor unit 225 that generates a change in impedance based on applied magnetism, and an amplification unit 226 that amplifies the amount of change in the impedance. More specifically, the sensor unit 225 has a pulse amplitude circuit (not shown) connected to an amorphous wire (not shown) made of an MI element (magnetic impedance element). In a situation where a pulse current is output from the pulse amplitude circuit to the amorphous wire, when the magnetism is applied to the amorphous wire, the impedance of the amorphous wire changes. Further, in the sensor unit 225, a pickup coil (not shown) is wound around the amorphous wire, and an induced voltage is generated in the pickup coil due to the change in the impedance. The amplifying unit 226 includes an operational amplifier and is connected to a pickup coil in the sensor unit 225. The amplifying unit 226 has a function of amplifying the induced voltage generated in the pickup coil according to a coefficient (sensitivity coefficient G) of 1 to N (N is a natural number). That is, in this embodiment, the magnetic detection value detected by the magnetic sensor 221 is amplified by 1 to N times by the amplifying unit 226.

  The relationship between the detection value amplified by the amplification unit 226 and the offset process as described above will be described with reference to FIG. FIG. 30B is an explanatory diagram for explaining the relationship between the sensitivity coefficient G and the detected value. In FIG. 30B, the detection values for the respective coefficients are displayed in an overlapping manner for comparison of the detection values.

  As already described, the offset process is a process of monitoring the detection value at the timing from Ta to Tb and changing the average value to 0 value. Whether the detection value is set to 0 value and the magnetic detection state. It can be said that the threshold value, which is a criterion for determining whether or not, is moved according to the surrounding magnetic level. Then, the determination of the coefficient (sensitivity coefficient G) when the detection value is amplified by the amplifying unit 226 is executed after this offset process (the detection process for adjustment shown in the figure corresponds to the process of determining the sensitivity coefficient G). ). The adjustment detection process will be described in detail later. In this process, the sensitivity coefficient G is determined by monitoring whether or not the detection value exceeds the threshold over a predetermined period. As described above, in the offset process, the zero value and the threshold value are moved in accordance with the surrounding magnetic level, but the difference between the threshold value after the offset process and the detected value may differ depending on the amplitude of the detected value. If the difference between the threshold value and the detection value is different, the threshold value may be exceeded or not exceeded even when magnetism of the same intensity is applied. Therefore, in the present embodiment, the amplitude of the magnetic detection value is adjusted by the sensitivity coefficient G after the offset processing.

  Here, in the present embodiment, unlike the first to third embodiments, the threshold value is a predetermined fixed value. And the value is set larger than the threshold value (threshold value of sensitivity levels 1 to 4) in the first to third embodiments. More specifically, the value is larger than the maximum value of magnetism assumed in the game hall (in this embodiment, five times the maximum value of magnetism assumed). The magnetism assumed in the game hall does not include improperly applied magnetism, but is, for example, magnetism caused by geomagnetism or various control devices, and is an internal factor in the installation state in the game hall. The effect of setting the threshold value to a value larger than the assumed maximum value of magnetism will be described in detail later.

  The adjustment detection process is executed in the second offset process of the magnetic sensor module 81. Here, the second offset processing in the present embodiment will be described with reference to the flowchart of FIG.

  In the second offset process in the present embodiment, the processes in steps S1701 to S1707 are executed in the same manner as the processes in steps S701 to S707, and then the adjustment detection process is executed in step S1708. That is, the adjustment detection process is executed after the second offset process is successful (step S1706: YES), and is executed after the zero value overwriting process (step S1707) is performed, and the second offset process is an error. If there is, it will not be executed. As already described, in the zero value overwriting process, the threshold value is updated together with the zero value. Therefore, the adjustment detection process is executed after updating the zero value and the threshold value.

  Here, the detection process for adjustment executed in step S1708 will be described with reference to the flowchart of FIG.

  First, in step S1801, processing for setting the numerical information of the sensitivity coefficient G provided in the RAM 224 to “1” is executed. As described above, the sensitivity coefficient G is used for amplification of the detection value. For example, when the sensitivity coefficient G is “2”, the detection value is amplified by the amplification unit 226 twice.

  In subsequent step S1802, the detection value is monitored. In step S1803, it is determined whether or not it is the monitoring end timing. If it is not the end timing, the process returns to step S1802. That is, in step S1802 and step S1803, as shown in FIG. 30B, the magnetism detection value is monitored over a predetermined period (period from Tb to Tc). In the present embodiment, 100 msec is set as the predetermined period.

  If it is the end timing in step S1803, the process proceeds to step S1804. In step S1804, it is confirmed whether or not the magnetism detection value monitored in step S1802 is equal to or greater than a threshold value.

  If a negative determination is made in step S1804, it is determined in step S1805 whether or not the sensitivity coefficient G is a predetermined value (20 in the present embodiment). If not, step S1806 is determined. After adding "1" to the sensitivity coefficient G, the process returns to step S1802, and the magnetism detection value is again monitored over a predetermined period.

  The predetermined value in step S1805 is normally set as a value sufficient to exceed the threshold value by amplifying the detection value according to the predetermined value. More specifically, the threshold value is set so as to exceed the threshold when the minimum detection value of magnetism assumed in the game hall is amplified according to the predetermined value. That is, if it is normal, before the sensitivity coefficient G reaches a predetermined value in step S1805, the detected value is equal to or greater than the threshold value in step S1802, and an affirmative determination is made in step S1804 (does not proceed to step S1805).

  If an affirmative determination is made in step S1804, it is determined in step S1807 whether or not the sensitivity coefficient G is “4” or less. As described above, the threshold value in the present embodiment is set to five times the maximum value of magnetism assumed in the game hall. Normally, although the sensitivity coefficient G is “4” or less, the step is performed. In S1804, an affirmative determination (detected value equal to or greater than the threshold value in Step S1802) is not made. If the sensitivity coefficient G is larger than “4” in step S1807, a process of subtracting a preset numerical value (set value) from the sensitivity coefficient G is executed in step S1808, and the process proceeds to step S1809. In step S1809, a process of storing the sensitivity coefficient G subtracted in step S1808 in the sensitivity coefficient storage area provided in the RAM 224 is executed, and the adjustment detection process ends.

  When the numerical value to be subtracted from the sensitivity coefficient G in step S1808 is increased, the width between the threshold value and the detected value is increased. When the numerical value to be subtracted is decreased, the width between the threshold value and the detected value is decreased. When magnetism of the same strength is applied, it becomes difficult to exceed the threshold when the width between the threshold and the detection value increases, and the threshold is easily exceeded when the width between the threshold and the detection value decreases. That is, it can be said that the numerical value subtracted from the sensitivity coefficient G in step S1808 indicates the sensitivity level. That is, in this embodiment, the sensitivity level is not defined by the 0 value and the threshold as in the first to third embodiments, but is a threshold defined by the numerical value subtracted from the sensitivity coefficient in step S1808. It is defined by the width of the detected value. A numerical value to be subtracted from the sensitivity coefficient G can be set by a game hall manager or the like. More specifically, the numerical value to be subtracted can be set to “1-4”. For this setting, the sensitivity level setting switch shown in the first embodiment is used. In the present embodiment, if the sensitivity level is to be lowered, the sensitivity level setting switch is operated to increase the value to be subtracted from the sensitivity coefficient G in step S1808, and if the sensitivity level is to be increased, the sensitivity level is subtracted. Decrease the value. The set numerical value information to be subtracted is transmitted to the magnetic sensor module 81 in step S801 of the sensor confirmation process (FIG. 19) on the main controller 122 side. On the magnetic sensor module 81 side, the information is read in the terminal reading process in step S301 of the startup process (FIG. 11), and a numerical value to be subtracted is set in step S1808.

  If the sensitivity coefficient G is “20” in step S1805, or if the sensitivity coefficient G is “4” or less in step S1807, the process proceeds to step S1810. As described above, the case where the sensitivity coefficient G is “20” in step S1805 means that the detection value should already exceed the threshold value (step S1804: YES) if it is normal. It is conceivable that the magnetic sensor module 81 is unable to detect magnetism due to some factor, such as a shield or the like around the sensor 221. Further, the case where the sensitivity coefficient G is “4” or less in step S1807 may be a case where the magnetism (noise) of the game hall is larger than expected. In step S1810, assuming that the magnetism cannot be normally detected, “1” is set in the error flag provided in the RAM 224, and the adjustment detection process is terminated.

  As already described, the threshold in this embodiment is set to a value larger than the maximum value of magnetism assumed in the game hall. If a threshold value is set within the range of magnetism assumed in the game hall, it is necessary to prepare a process for raising and lowering the sensitivity coefficient G. Therefore, setting the threshold as in the present embodiment requires only increasing the sensitivity coefficient G in steps S1802 to S1806, and the sensitivity coefficient G can be determined with a simple processing configuration.

  Returning to the description of the second offset process (FIG. 31), after the process of step S1708 is executed, it is determined in step S1709 whether or not “1” is set in the error flag. If “1” is not set in the error flag, the detection state signal is set to the LOW level signal in step S1710, and the second offset processing is ended. On the other hand, if “1” is set in the error flag, the detection state signal is set to the HI level signal in step S1711 and the second offset processing is ended.

  Therefore, in the present embodiment, the second error notification is performed not only when the offset process is an error but also when the adjustment detection process is an error. Thereby, the administrator of the game hall and the like can perform a predetermined treatment based on the second error notification. The case where the adjustment detection process is an error is a case where the magnetic sensor module 81 cannot detect magnetism or a case where noise is larger than expected, as described above. In the former case, a treatment for confirming the presence or absence of a member that shields magnetism around the magnetic sensor module 81 or a treatment for replacing the magnetic sensor module 81 itself can be considered. In the latter case, the cause of the noise is investigated (for example, whether or not a device that outputs electromagnetic waves is attached to the surroundings), and the cause of the cause is removed, or the attachment position of the magnetic sensor module 81 is redesigned. Conceivable. By leaving room for such treatment, magnetic detection processing is performed on the magnetic sensor module 81 side despite the fact that magnetism cannot be detected due to the failure of the magnetic sensor module 81 itself or the surrounding environment. It becomes possible to suppress that.

  In addition, it is good also as a structure by which different alerting | reporting is performed by the case where it becomes an error in the detection process for adjustment, and the case where it becomes an error in an offset process. In this case, the manager of the game hall can identify which process is the cause of the error, and can deal with it smoothly. Further, in these cases, information for making the management computer of the game hall recognize may be used.

  Although not shown in the figure, the configuration for detecting that the second offset processing has been completed on the main controller 122 side is the adjustment detection processing because the adjustment detection processing is performed in the second offset processing. It is the structure which grasps that it was also completed including. Specifically, in step S1008 in the sensor correction process (FIG. 21), “600” is set in the offset counter OT. Thereby, after instructing the magnetic sensor module 81 to perform the offset process (step S1011), it is grasped that the second offset process is completed (in step S1012, it is confirmed that the offset counter OT is “0”). The period until this is 2400 msec, which is longer than the period during which the second offset process is performed (400 to 2300 msec) including the adjustment detection process.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In the magnetic sensor module 81, the amplitude (sensitivity coefficient G) of the detected value can be adjusted by the amplifying unit 226. Although the 0 value and the threshold value are changed by the offset processing as described above, the difference between the changed threshold value and the detected value differs depending on the detected value amplitude, and thus the detected value amplitude can be changed in this way. Thus, the sensitivity level can be adjusted more accurately.

  As a configuration for changing the amplitude of the detected value, the threshold value is set to a value larger than the assumed magnetism (internal factor). Thereby, since only the sensitivity coefficient G needs to be increased in the adjustment detection process, the sensitivity coefficient G can be determined with a simple processing configuration.

  In determining the sensitivity coefficient G, the coefficient is lowered by a predetermined numerical value compared to the case where a detection value exceeding the threshold is detected. The predetermined numerical value can be changed by a game hall manager or the like. Since the detection process for adjustment can be said to be a process for determining the width between the threshold value and the detection value, it can be said that the numerical value serving as the reference for the width indicates the sensitivity level. Therefore, in this embodiment, the sensitivity level of the magnetic sensor module 81 can be changed by making the numerical value changeable.

  The adjustment detection process is executed after the zero value and the threshold value are updated in the second offset process. In the configuration in which the process of determining whether to enter the magnetic detection state using the 0 value and the threshold value, the strength of the noise is determined by the relationship between the 0 value and the threshold value (particularly the threshold value). Because. If the sensitivity coefficient G is determined by determining the noise level before updating the 0 value and the threshold value, the previous determination of the noise level may be overturned by the updated 0 value or threshold value. There is also. Specifically, for example, even if the sensitivity coefficient G is determined at a level where the noise does not exceed the threshold before the 0 value and the threshold are updated, the 0 value and the threshold are updated to the plus side. The difference between the threshold and noise becomes larger than before the update. Therefore, by adopting a configuration in which the adjustment detection process is executed after the update as in the present embodiment, the relationship between the noise and the threshold is not disrupted, and magnetism applied for illegal purposes in the subsequent magnetic detection process is preferable. It becomes possible to specify.

<Fifth Embodiment>
In the present embodiment, the adjustment detection process shown in the fourth embodiment is performed instead of the offset process. A specific configuration will be described below.

  First, the startup process of the magnetic sensor module 81 in the present embodiment will be described with reference to the flowchart of FIG.

  In the start-up process according to the present embodiment, first, a terminal reading process is executed in step S1901 as in step S301. In the terminal reading process, a numerical value to be subtracted from the sensitivity coefficient G in the adjustment detection process is set based on the detection sensitivity setting signal from the main controller 122 as described above. In a succeeding step S1902, the first adjustment detection process is executed.

  Here, the first adjustment detection process will be described with reference to the flowchart of FIG.

  The first adjustment detection process is substantially the same as the adjustment detection process (FIG. 32). The first difference is that a determination process is performed between step S1802 and step S1803 to determine whether the detected value being monitored is an error target. Specifically, similar to the processing in step S1801 and step S1802, after executing the processing in step S2001 and step S2002, it is determined in step S2003 whether or not the target of the error. The case of being an error target is when the detected value being monitored greatly exceeds the threshold, and when the fluctuation width between the highest and lowest detected values being monitored is greater than or equal to a predetermined value. . That is, this corresponds to a case where strong magnetism is applied during the offset processing shown in the first to fourth embodiments, or a case where the inner frame 13 is opened and closed during the processing. If it is not an error target, the process proceeds to step S2004, where it is determined whether it is the end timing, and if it is not the end timing, the process returns to step S2002.

  If it is the end timing in step S2004, the processing of steps S2005 to S2010 is executed in the same manner as the processing of steps S1804 to 1809, and the first adjustment detection processing is ended. However, in the present embodiment, the predetermined value determined in step S2006 is “40”, which is set to be larger than that in the fourth embodiment. In step S2008, it is determined whether or not it is “8” or less, which is also larger than that of the fourth embodiment. This is due to the fact that in this embodiment, the threshold is set larger than that in the fourth embodiment. In the fourth embodiment, the adjustment detection process is performed after the offset process, and the detection value of the adjustment detection process is less than the threshold value to some extent by the offset process. Although the value is larger than the maximum value, it is not necessary to set the value so large. On the other hand, in the present embodiment, since the adjustment detection process is performed without performing the offset process, a value larger than the threshold value of the fourth embodiment in advance (specifically, the maximum value of magnetism assumed). The detection value is set to be lower than the threshold value in the adjustment detection process. Since the threshold value is set to be large as described above, the numerical value for determining whether or not the magnetic sensor 221 has failed or the like in step S2006 as described above, and the noise level is determined to be higher than expected in step S2008. Numerical values are set larger than those in the fourth embodiment. The above is the second difference from the adjustment detection process (FIG. 32).

  Returning to the description of the first adjustment detection process (FIG. 34), when an error is detected in step S2003, the sensitivity coefficient G is “40” in step S2006, or the sensitivity coefficient G is determined in step S2008. If it is “8” or less, the process advances to step S2010 to input a negative value to the detection value as an error value, and the first adjustment detection process ends.

  Returning to the description of the startup process (FIG. 33), after the first adjustment detection process is executed in step S1902, it is determined in step S1903 whether the first adjustment detection process is successful. Specifically, it is possible to determine whether or not the first adjustment detection process is successful by confirming whether or not a negative value is input as the detection value. If the first adjustment detection process has succeeded in step S1903, the start-up process ends. If not successful, as in steps S304 and S305, the RAM 224 is cleared in step S1904, the detection state signal is set to the HI level signal in step S1905, and the process returns to step S1902. The first adjustment detection process is executed again.

  Next, normal processing of the magnetic sensor module 81 in the present embodiment will be described with reference to the flowchart of FIG.

  In the normal process in the present embodiment, first, the magnetic detection process is executed in step S2101 as in step S501. In a succeeding step S2102, an adjustment signal reading process is executed. In this embodiment, the main controller 122 is configured to transmit an adjustment signal to the magnetic sensor module 81 instead of the offset signal. Specifically, in step S1011 in the sensor correction process (FIG. 21), the adjustment signal is set to the HI level signal, and in step S1018, the adjustment signal is set to the LOW level signal. Further, in steps S906 and S1001, it is determined whether or not the adjustment signal is being output as a HI level signal.

  In the following step S2103, it is determined whether or not the adjustment signal has been switched from the LOW level signal to the HI level signal. If switched, “1” is set to the adjustment in-progress flag provided in the RAM 224 in step S2104. . The in-adjustment flag corresponds to the above-described offset flag.

  If a negative determination is made in step S2103, or after the process of step S2104 is executed, the process proceeds to step S2105. In step S2105, it is determined whether or not “1” is set in the adjustment in progress flag. If it is set, the second adjustment detection process is executed in step S2106, and then the normal process ends. To do. If “1” is not set in the adjustment-in-progress flag in step S2105, the normal process is terminated as it is.

  Here, the second adjustment detection process executed in step S2106 will be described with reference to the flowchart of FIG.

  The second adjustment detection process is substantially the same process as the first adjustment detection process (FIG. 34). As a difference, when an error is caused as described above, the detection state signal is set to the HI level signal without waiting for the end of the second adjustment detection process, and the process ends without an error. In this case, the detection state signal is set to a LOW level signal.

  Specifically, the processing of step S2201 to step S2210 is performed similarly to step S2001 to step S2010. After the sensitivity coefficient G is stored in step S2210, the detection state signal is set to a LOW level signal in step S2211, and the second adjustment detection process ends. Also, if an error is detected in step S2203, if the sensitivity coefficient G is “40” in step S2206, or if the sensitivity coefficient G is “8” or less in step S2208, step In S2212, the detection state signal is set to the HI level signal, and the second adjustment detection process ends.

  As another change of the process on the main controller 122 side, in the standby process of step S802 in the sensor confirmation process (FIG. 19), the process waits until the first adjustment detection process is completed, specifically, 4000 msec. . Therefore, the processing period when the power is turned on is longer than that in the fourth embodiment.

  On the other hand, in step S1008 in the sensor correction process (FIG. 21), “10” is set in the offset counter OT, and the period required until the offset counter OT becomes “0” is longer than that in the first embodiment. Also set to be a short period. This is a numerical value corresponding to 20 msec which is the minimum period in which the magnetic sensor module 81 can specify that the adjustment signal has been switched from the LOW level signal to the HI level signal. When the main controller 122 receives the detection state signal of the HI level signal while outputting the adjustment signal as the LOW level signal, the detection state flag is set to “1” in the detection state signal reading process (FIG. 20). It sets (step S901: YES, step S906: NO), and performs the same processing as when magnetism is detected in the magnetism detection processing (FIG. 22). In the present embodiment, in the case where an error is detected in the second adjustment detection process as described above, the detection state signal is set to the HI level signal without waiting for the end of the second adjustment detection process. In this case, it is preferable to notify immediately. In addition, since the first adjustment detection process is performed before the second adjustment detection process, an error in the second adjustment detection process is highly likely to have been applied with magnetism for illegal purposes. Therefore, with the configuration as described above, the processing period of the first adjustment detection process becomes longer, but if an error occurs in the second adjustment detection process, the game hall manager immediately identifies it. It becomes possible to do.

  Note that different notifications may be performed when magnetism is detected in the magnetic detection process and when an error occurs in the second adjustment detection process.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In the first embodiment, the adjustment detection process is executed instead of the offset process. Specifically, the adjustment signal that triggers the second adjustment detection process is changed from the LOW level signal to the HI level signal on the condition that the inner frame 13 is closed in the sensor correction process on the main controller 122 side. Can be switched. Therefore, similarly to the second offset process in the first embodiment, the second adjustment detection process in the present embodiment is the timing after the initial drive on the main controller 122 side is completed, and the inner frame 13 Is executed on the condition that is closed. By setting it as such a structure, the sensitivity coefficient G can be determined, without taking into consideration the magnetism which generate | occur | produces from each control apparatus etc. which were provided in the other pachinko machine 10.

  The adjustment detection process is a process for adjusting the amplitude of the magnetic detection value to the surrounding magnetic strength (noise level) in relation to the threshold value. On the other hand, the offset process is a process of changing the threshold value and the zero value according to the strength of the surrounding magnetism. Therefore, even when the adjustment detection process is executed instead of the offset process, it is possible to avoid the inconvenience of performing the subsequent magnetic detection process in consideration of at least the surrounding magnetism.

  A predetermined threshold value was set larger than that in the fourth embodiment. More specifically, in the fourth embodiment, it is set larger than the maximum value of magnetism assumed in the game hall, and in this embodiment, it is set larger than the threshold value in the fourth embodiment. . Therefore, even when the offset process is not performed, the process of monitoring the detection value in the adjustment detection process can avoid the inconvenience of suddenly exceeding the threshold value. Thereby, it is only necessary to increase the sensitivity coefficient G in the adjustment detection process, and the sensitivity coefficient G can be determined with a simple processing configuration.

  In addition, in the offset process, for example, when the surrounding magnetism is weak with respect to the threshold value, the zero value is set near the detection limit (lower limit) of the magnetic sensor module 81, so that the stable setting is not performed. There is a possibility. In this regard, in the adjustment detection process, the amplitude of the detection value is set in accordance with the strength of the surrounding magnetism. Therefore, even when the surrounding magnetism is weak, the setting on the magnetic sensor module 81 side is stably performed. It becomes possible. In this respect, there is an advantage that the adjustment detection process is performed instead of the offset process.

  However, the detection processing for adjustment is a configuration in which the sensitivity coefficient G is set by the amplification unit 226, and the offset processing is a configuration in which the magnetic sensor module 81 is set by software processing. From the viewpoint of simplification, a configuration in which the magnetic sensor module 81 is set by offset processing is suitable.

  In addition, since the threshold value is larger than that in the fourth embodiment as described above, the number of processing times for monitoring whether or not the detection value exceeds the threshold value in the adjustment detection processing is larger than that in the fourth embodiment. And the processing time becomes longer. In this respect, the configuration that performs the offset process and the adjustment detection process as in the fourth embodiment is superior.

<Other embodiments>
In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows. Incidentally, each of the following configurations may be individually applied to each of the above embodiments, or a part or all of them may be combined and applied to each of the above embodiments.

  (1) In each of the embodiments described above, after the main controller 122 causes the magnetic sensor module 81 to perform the offset process (adjustment detection process), the offset process (the offset process again) even if the inner frame 13 is opened and closed. The adjustment detection process is not executed, but may be executed again. With this configuration, offset processing (adjustment detection processing) is executed even while the game hall is in operation, and offset processing (adjustment detection processing) is executed in a state closer to the state in which the pachinko machine 10 is normally driven. Can be made. However, in this case, as described above, there is a concern about the act of improperly applying magnetism during the offset process (adjustment detection process) to calibrate the detection value with an incorrect value or to determine the sensitivity coefficient G. However, even in this case, the magnetic sensor module 81 is configured to input an error value when the magnetism of a predetermined value or more is detected during the offset process (adjustment detection process). Can be suppressed.

  (2) In each of the above embodiments, the timing at which the magnetic sensor module 81 executes the offset process (adjustment detection process) is not limited to the above. From the viewpoint of excluding changes in magnetism and magnetic field generated at power-on, each control device at power-on of the pachinko machine 10 is caused to execute an offset process (adjustment detection process) after the initial drive is completed. Any configuration may be used. For example, the offset process (adjustment detection process) may be executed when the number of times of the timer interrupt process (FIG. 10) periodically executed after power-on reaches a predetermined number. A timer counter that counts the period may be provided, and an offset process (adjustment detection process) may be executed when the timer counter reaches a predetermined value. The voltage value monitored by the power interruption monitoring board 202 becomes a predetermined value. In such a case, an offset process (adjustment detection process) may be executed.

  Further, from this point of view, a configuration may be adopted in which a clock circuit or the like is provided on the power supply path to the magnetic sensor module 81 so that power is supplied to the magnetic sensor module 81 after a predetermined period of time has elapsed after the pachinko machine 10 is turned on. Good. In this case, the magnetic sensor module 81 may be turned on after the initial drive of each control device.

  Further, after the initial driving of the various control devices, the offset processing (adjustment detection processing) may be executed at the timing when each processing of the timer interrupt processing is executed, for example, when the game ball is fired. The offset processing (adjustment detection processing) may be executed at the timing when the prize ball is paid out from the payout device 154, and any one of the drive units connected to each control device is in the drive state. The offset processing (adjustment detection processing) may be executed at the timing.

  (3) The magnetic sensor module 81 is configured to be connected to the main control board 201 of the main control apparatus 122 from the inner frame opening switch 13a via the power supply and launch control apparatus 163, and the offset signal from the main control board 201 (adjustment) The offset processing (adjustment detection processing) is executed based on the signal). However, the offset processing (adjustment detection processing) may be connected to the inner frame opening switch 13a via another control device, or directly connected to the inner frame opening switch 13a. It is good also as a structure to be made. In the case of a configuration connected to the inner frame opening switch 13a via another control device, an offset signal (adjustment signal) may be output from the other control device to the magnetic sensor module 81. In the case of a configuration directly connected to 13a, the MPU 222 of the magnetic sensor module 81 is added with a process for identifying HI / LOW of the inner frame release signal from the inner frame release switch 13a, and an offset process (adjustment detection process) is performed. It may be configured to determine the timing to be executed by itself.

  (4) In each offset process, as in the fifth embodiment, when a magnetism of a predetermined reference value or more is detected in the detection value integration process, and the blur width of a predetermined width or more in the averaging process In this case, an error value may be input to the detected value and the error information may be output to the main control device 122 side. Specifically, when an error value is input to the detection value, the detection state signal is set to the HI level signal in the first, third, and fourth embodiments, and the error signal is set to the second embodiment. It is good also as a structure to output. Thereby, notification (each error notification) when magnetism is improperly applied during the offset processing can be executed earlier, and the hall manager can identify the fraudulent act more quickly.

  (5) If the inner frame 13 is opened during the offset process (second adjustment detection process) of the magnetic sensor module 81, an error may be generated. More specifically, when the offset signal (adjustment signal) is output as the HI level signal in the reading process (step S209) of the timer interrupt process (FIG. 10), the inner frame release signal becomes the HI level signal. In such a case, a process of setting “1” to the error flag may be added. As already described, an error occurs when the fluctuation width of the detected value during the offset process (second adjustment detection process) exceeds a predetermined value, but the predetermined value is an absolute value. Since the fluctuation of the detection value due to the opening and closing of the inner frame 13 is relative, it may be assumed that no error occurs even if the inner frame 13 is opened during the offset process (second adjustment detection process). The For example, during offset processing (second adjustment detection processing), the inner frame 13 is opened to the extent that an illegal jig can be inserted, and magnetism is applied to set the zero value by the offset processing (second adjustment detection processing) to the plus side. An illegal act of shifting to (in the case of the second adjustment detection process, lowering the sensitivity coefficient G) is conceivable. On the other hand, according to this configuration, if the inner frame 13 is released during the offset process (second adjustment detection process), an error occurs and error notification is executed. Even if the fluctuation range of the detected value during the detection process) is less than the predetermined value, it is possible to specify the fraud.

  (6) The magnetic sensor 221 of the magnetic sensor module 81 is not limited to an MI element, and may be a Hall element, an MR element, or the like, and at least the MPU 222 can calibrate the magnetic detection value or magnetic. What is necessary is just to be connected so that the amplitude of the detection value of the sensor 221 can be changed.

  Also, when using a switching type magnetic detection sensor, connect the magnetic detection sensor to the main control device 122, and when the magnetism is detected, the resistance value of the current is determined from the size of the contact surface between the switches that contact each other. It is good to calculate and use as a magnetism detection value. Thereby, even if it is a switching type magnetic detection sensor, it becomes possible to calibrate the magnetic detection value.

  Furthermore, the configuration is not limited to the configuration in which the detection value is amplified by the amplification unit 226 as in the fourth and fifth embodiments. For example, the detection value is amplified by changing the voltage output to the sensor unit 225, the pulse amplitude, or the like. It is good also as a structure.

  (7) The magnetic sensor module 81 is configured to be in a magnetic detection state when magnetism is detected a plurality of times (three times) during 60 msec, which is a period shorter than the game ball launch cycle in the game ball launch mechanism 40. The period is not limited to 60 msec as long as it is shorter than the game ball firing cycle (0.6 sec), and may be longer or shorter.

  Moreover, you may set to a period shorter than the drive period of another drive part. For example, the drive cycle for opening and closing the variable winning device 54 may be a period shorter than the round cycle of the opening / closing execution mode, or may be a period shorter than the cycle in which the payout device 154 pays out game balls.

  It goes without saying that the number of times of detection in the magnetic detection state within these set periods is not limited to three as long as it is a plurality of times.

  (8) The magnetic sensor module 81 is configured to execute only the magnetism applied from the front in the azimuth filter processing (step S507 in FIG. 15), but the configuration is to extract the magnetism applied from the rear. Alternatively, the configuration may be such that magnetism applied from above or below is extracted, or the configuration may be such that the magnetism in each direction is combined or extracted entirely. By setting magnetism applied from other than the front as the detection target, it is possible that other than improperly applied magnetism may be included in the detection target, but illegally applied magnetism is not limited to the front. It is a powerful anti-fraud measure. Further, by increasing the orientation to be extracted, the degree of freedom in the mounting direction when the magnetic sensor module 81 is installed in the pachinko machine 10 is increased, and the installation work can be simplified.

  Moreover, it is good also as a structure from which the threshold value of the magnetism detection value of each of these directions differs, respectively. In this case, the magnetism generated from each control device can be configured not to be detected by setting the threshold value of the magnetism detection value from the rear to be larger than the threshold value of the magnetism detection value from the front. .

  (9) The magnetic sensor module 81 is composed of the three-axis magnetic sensor 221 and is configured not to detect magnetism from the rear by azimuth filtering, but the magnetic sensor module 81 is made of a member having low permeability such as aluminum. It is good also as a structure which covers back and shields the magnetism from back.

  (10) The mounting position of the magnetic sensor module 81 is not limited to the above. For example, it may be provided on the front door frame 14 or may be provided on the gaming machine main body 12 side. Further, the magnetic sensor module 81 is configured to execute the second offset process (second adjustment detection process) when the inner frame 13 is in the closed state. However, when the front door frame 14 is in the closed state, the magnetic sensor module 81 It is good also as a structure which performs 2 offset process (2nd adjustment detection process), and also when it is the structure which performs a 2nd offset process (2nd adjustment detection process) when both the frames 13 and 14 are closed. Good. In these cases, at least the magnetic sensor module 81 has the inner frame 13 or the front door frame 14 in order to adjust the 0 value (sensitivity coefficient G) to the normal state of the gaming machine by the second offset processing (second adjustment detection processing). Or a configuration in which the inner frame 13 or the front door frame 14 is provided at a position included in the detection range in the gaming machine main body 12. Even if it is provided on the gaming machine main body 12 side, when the inner frame 13 or the front door frame 14 is opened, the position change of the electric device having the metal plate provided on these frames 13 and 14 As a result of this, a change in the magnetic field occurs, and the second offset process (second adjustment detection process) is executed with the inner frame 13 in the closed state, thereby setting a zero value (sensitivity coefficient G) without taking the change in the magnetic field into account. can do.

  (11) The sensor confirmation process (FIG. 17) is configured to be executed in the main process. However, the present invention is not limited to this. For example, the sensor confirmation process may be performed in the timer interrupt process, or may be performed in the sensor correction process in the timer interrupt process. It is good also as a structure. However, since the configuration executed in the main process confirms the magnetic sensor module 81 before the game is performed, the game is not performed when the magnetic sensor module 81 is abnormal. Is excellent.

  (12) The detection state signal is input to the main control device 122. However, the present invention is not limited to this. For example, the detection state signal may be input to the sound lamp control device 113 and input to the payout control device 162. It may be a configuration. Alternatively, the detection state signal may be directly output to the management control device of the game hall via the external terminal board 143.

  (13) The main control board 201 is configured to be supplied with operating power from the power supply and launch control device 163 via the power interruption monitoring board 202. However, the configuration is not limited to this, and the power interruption monitoring board 202 is omitted. Also good. In this case, it is necessary to provide a circuit for monitoring the voltage on the main control board 201.

  (14) In each offset process, the detected values are integrated over a predetermined period and the average value is set to 0 value. For example, the maximum value and the minimum value of the detected values are averaged to be 0 value. Also good. In this case, it is possible to simplify the process, and it is possible to reduce the inconvenience that the maximum value of the detected value due to the surrounding magnetism exceeds the threshold value after the 0 value is updated.

  (15) In the adjustment detection process, the threshold is set to a value larger than the assumed magnetism and the sensitivity coefficient G is increased. However, the threshold is set to a value smaller than the assumed magnetism and the sensitivity coefficient G is set. It is good also as a structure which lowers. In this case, for example, in the fourth embodiment, the sensitivity coefficient G is set to “20” in step S1801, and it is configured to monitor whether or not the maximum detected value falls below the threshold value in step S1802. In step S1804, an affirmative determination is made when the maximum detected value falls below the threshold value. If not, it is determined in step S1805 whether the sensitivity coefficient G is “4”. If it is not “4”, “1” is subtracted from the sensitivity coefficient G in step S1806, and the process returns to step S1802. If the determination in step S1804 is affirmative, it is determined in step S1807 whether or not the sensitivity coefficient G is “20”. If it is not “20”, after subtracting the set value from the sensitivity coefficient G in step S1807, the sensitivity coefficient G after the subtraction is stored in the RAM 224 in step S1809, and the adjustment detection process is terminated. If “4” in step S1805 or “20” in step S1807, “1” is set in the error flag in step S1810, and then the adjustment detection process is terminated. In this case, if the above threshold value is set to be normal, the sensitivity coefficient G is set to “4” and the detected value is lower, so that it is possible to make an abnormality when the noise is large. Further, since it is configured to monitor that the maximum detected value is below the threshold value, the set values to be subtracted in step S1807 are “4” → “3”, “3” → “2”, “2”. “→” 1 ”,“ 1 ”→“ 0 ”.

  Further, in the fifth embodiment, each adjustment detection process is changed in correspondence with the above-described configuration as being smaller than the threshold value in the configuration changed as described above (for example, half). In this case, as a process for determining an abnormality (such as a failure of the magnetic sensor 221) that falls below the threshold value even though the sensitivity coefficient G is sufficiently large, if the threshold value is halved as described above, The sensitivity coefficient G input in step S2001 (step S2201) and the sensitivity coefficient G monitored in step S2006 (step S2206) may be set to “10”, which is half of the above “20”.

  (16) In the detection process for adjustment, the sensitivity coefficient G may be changed to a value smaller than “1”. In this case, for example, when the sensitivity coefficient G is “0.5”, the detection value is halved compared to the case where the sensitivity coefficient G is “1”. Adding this configuration to the configuration (15) is effective when the maximum detection value does not fall below the set threshold, for example, when noise is unexpectedly large.

  (17) The adjustment detection process may be configured to determine whether to increase or decrease the sensitivity coefficient G according to the relationship between the surrounding magnetic level and the threshold value. In this case, it is not necessary to set the threshold value to be larger (smaller) than the assumed magnetism, and the number of repetitions of the process for monitoring the detection value can be reduced. For example, the threshold value is set near the average value of magnetism assumed in the game hall, and the sensitivity coefficient G is detected as a predetermined value (for example, “10”) before performing the adjustment detection process (for example, before step S1801). The value is compared with the threshold value. Then, based on the result of this comparison, it may be determined whether to increase or decrease the sensitivity coefficient G. When the sensitivity coefficient G is increased, the process shown in the fourth and fifth embodiments is performed. When the sensitivity coefficient G is decreased, the process described in (15) is preferably performed.

  (18) In the adjustment detection process, the sensitivity coefficient G is a predetermined value (“4” in the fourth embodiment, “8” in the fifth embodiment) or less in step S1807, step S2008, and step S2208. In this case, an error is set, but a process of monitoring whether the detected value exceeds the threshold may be started from the sensitivity coefficient G of the predetermined value. In this case, if the detected value exceeds the threshold with the sensitivity coefficient G of the predetermined value, the number of times of monitoring-related processing can be reduced by adopting an error configuration. However, in this case, it is necessary to separate the process related to the initial monitoring and the process related to the subsequent monitoring (after increasing the sensitivity coefficient G), which may complicate the processing configuration.

  (19) In the adjustment detection process, the sensitivity coefficient G is changed. However, the threshold value may be changed depending on the strength of surrounding magnetism. Specifically, the magnetism detection value is monitored over a predetermined period. If the threshold value is not exceeded, the threshold value is lowered and the magnetism detection value is monitored again. A threshold value that is larger by a predetermined amount than the threshold value at the time when the detected value exceeds the threshold value may be set as the actual threshold value. In this case, the predetermined amount may be set by a sensitivity level setting switch. By adopting such a configuration, it is not necessary to provide a function (amplifying unit 226) for amplifying the detection value, and the setting on the magnetic sensor module 81 side can be changed according to the strength of surrounding magnetism by software processing. Is possible.

  (20) In the adjustment detection process, the detection value is monitored over a predetermined period. However, for example, the sensitivity coefficient G may be gradually increased regardless of the predetermined period. In this case, since the detection value is not repeatedly monitored over a predetermined period in the adjustment detection process, the period during which the adjustment detection process is performed can be shortened. However, in this case, there is a possibility that the sensitivity coefficient G is determined with respect to the maximum value and the minimum value of the surrounding magnetic change. If the sensitivity coefficient G is determined based on these maximum and minimum values, the subsequent magnetism detection value becomes too large or too small, and it is difficult to appropriately specify the improperly applied magnetism. Therefore, such inconvenience can be avoided by adopting a configuration in which monitoring is performed over a predetermined period as described above.

  (21) The sensitivity level of the magnetic sensor module 81 can be set by a game hall manager or the like using a sensitivity level setting switch. However, the sensitivity level can be set within the processing of the main controller 122 or the magnetic sensor module 81. It is good also as a simple structure. From this point of view, in the fourth and fifth embodiments, the amplitude of the detected value of the surrounding magnetism can be adjusted with respect to the threshold value set by performing the adjustment detection process. It can be said that the setting of the magnetic sensor module 81 can be changed according to the strength of the surrounding magnetism, even if the manager of the hall does not change the threshold value (sensitivity level).

  (22) The main controller 122 or the magnetic sensor module 81 may have a function of storing the result of the second offset processing (second adjustment detection processing) in the RAM 213 or the RAM 224. By setting the stored result until the RAM 213 or RAM 224 is cleared, the offset process (adjustment detection process) can be omitted when the power is turned on daily. More specifically, when the result is stored on the magnetic sensor module 81 side, a zero value is obtained based on the result on the condition that the result is stored in the RAM 224 in the start-up process at power-on. The threshold value (sensitivity coefficient G) is set, and the offset process (adjustment detection process) is not performed. And when it sets in this way, it is good to set it as the structure which does not perform a 2nd offset process (detection process for 2nd adjustment).

  When the result is stored on the main controller 122 side, the magnetic sensor module 81 specifies the result to the main controller 122 after the second offset process (second adjustment detection process) on the magnetic sensor module 81 side. The main control device 122 stores the result in the RAM 213 based on the signal. Then, when the result is stored in the main process when the power is turned on, main controller 122 transmits a signal that causes magnetic sensor module 81 to set a zero value or a threshold (sensitivity coefficient G) based on the result. . In the start-up process on the magnetic sensor module 81 side, when a signal to be set is received from the main controller 122 side, a zero value and a threshold value (sensitivity coefficient G) are set based on the signal, and an offset process (detection for adjustment) The processing is not performed. And when it sets in this way, it is good to set it as the structure which does not perform a 2nd offset process (detection process for 2nd adjustment).

  In general, the pachinko machine 10 is not moved frequently after being installed in the island facilities of the game hall. That is, once installed in the island facility, it is assumed that the fluctuation of the geomagnetism around the pachinko machine 10 is not large thereafter. Thus, when it is assumed that fluctuations in the surrounding geomagnetism or the like are not large, the zero value and the threshold value (sensitivity coefficient G) once determined are repeatedly used, and the offset process (adjustment detection process) is omitted. By doing so, it is possible to smoothly perform startup at the time of daily power-on. Further, when it is desired to change the 0 value and the threshold value (sensitivity coefficient G), the RAM 213 or the RAM 224 may be cleared. For example, when a symptom such as an abnormal magnetic detection state occurs, a pachinko machine For example, when 10 installation locations are moved, the RAM 213 or the RAM 224 may be cleared to determine the 0 value and the threshold value (sensitivity coefficient G) again.

  In these cases, the configuration stored on the main control device 122 side can simplify the configuration of the magnetic sensor module 81. If the RAM 224 of the magnetic sensor module 81 can be stored for a long period of time, a large-capacity capacitor or the like needs to be mounted on the magnetic sensor module 81 in order to secure a backup power source for the RAM 224 at the time of power interruption. On the other hand, generally, a capacitor or the like as a backup power source at the time of power interruption is already mounted on the main control device 122 side, and the above-described capacitor or the like on the main control device 122 side already installed is used. By setting it as the structure which memorize | stores a result, it becomes possible to reduce the addition of the further member (capacitor) as the pachinko machine 10 whole.

  (23) In addition to the magnetic sensor module 81 for detecting magnetism, the present invention can be applied to detection means for detecting other specific events. Examples of detection means for detecting other specific events include radio wave detection means for detecting radio waves, entrance detection means for detecting the entry of game balls into the opening, and vibration detection means for detecting vibrations. It is done.

  (24) Other types of pachinko machines different from the above embodiment, for example, a pachinko machine in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or a game ball in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when entering, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. Or, if a specific symbol or a combination of specific symbols is established on an active line visible from the display window after the reel has stopped after a predetermined period of time, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  In addition, a pachinko machine and a slot machine that have a take-in device and start rotation of a reel by operating a start lever after a predetermined number of game balls stored in the storage unit are taken in by the take-in device The present invention can also be applied to a gaming machine in which is integrated.

  Even in the case of these gaming machines, the relative relationship between the detection value and the zero value in various detection means used in the gaming machine is adjusted (for example, after the startup process at the time of power-on as in each of the above embodiments) By adjusting when the door body is closed), it is possible to prevent the various detection means from being erroneously detected due to the surrounding environment.

<Invention Group Extracted from Each Embodiment>
Hereinafter, the characteristics of the invention group extracted from each of the above-described embodiments will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in each of the above embodiments is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

  The following features are: “There is a pachinko machine as a kind of gaming machine. In the pachinko machine, a winning lottery is performed based on, for example, a game ball launched into the game area entering the operation port. When the winning state is won, for example, symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, and then the variable pitching device provided in the game area is opened and closed. Then, the player is given a privilege that the game balls are paid out according to the number of balls entered into the variable pitching device, where the pachinko machine detects the occurrence of a specific event corresponding to the fraudulent act. For example, a fraudulent act that uses a magnet to guide a game ball to a place that is advantageous to the player, such as an operating port, may be performed. A magnetic sensor for detecting magnetism is provided, and a notification is given when the magnetic sensor detects magnetism, but magnetism can also be generated by normal operations of various devices provided in the pachinko machine. The magnetic field can also change depending on the surrounding environment where the machine is provided, etc. Therefore, in such a situation, in detecting the magnetism based on the fraudulent act, it may lead to erroneous detection of the magnetic sensor. The problem is not limited to a magnetic sensor that detects magnetism, but also applies to, for example, a detection sensor that detects radio waves and vibrations, and is not limited to a pachinko machine. The same applies to the other gaming machines that are used. "This is to solve the technical background and problems.

<Feature A group>
Feature A1. The detection value fluctuates when a specific event (for example, magnetism) occurs, and the specific output (detection state signal is output based on the amount of change in the detection value with respect to the reference value (0 value) reaching a predetermined value (threshold value). Detecting means (magnetic sensor module 81) for performing switching to the HI level signal;
Corresponding process execution means (magnetic detection in MPU 211 of main control unit 122) that executes corresponding processing (steps S1105 and S1106 in MPU 211 of main control unit 122) based on the detection unit performing the specific output. Function to execute processing)
With
The detection means includes a change means (a function of executing a second offset process in the MPU 222 of the magnetic sensor module 81) that changes the reference value according to the detection value.
Determination means for determining whether or not the adjustment condition is satisfied (function for executing sensor correction processing in the MPU 211 of the main control device 122);
When the determination means determines that the adjustment condition is satisfied, the command means (main control device 122) performs an adjustment command for the reference value (switches the offset signal to the HI level signal) to the detection means. In step S1011, step S1509 or step S1604 in the MPU 211)
With
The game machine according to claim 1, wherein the changing means changes the reference value according to the detected value when the command means issues the adjustment command.

  According to the feature A1, the detection unit can change the reference value that is a reference for performing the specific output when the adjustment condition is satisfied. Since the detection means is configured to perform specific output when the amount of change with respect to the reference value reaches a predetermined amount, depending on the changed reference value, the detection value may reach the predetermined value even if the detection value changes by the same amount. For example, the predetermined value may not be reached. Therefore, the reference value should be changed on the basis of the normal state of the gaming machine in which a game is played by a player who has a high possibility of fraud. For example, if the reference value is changed by the startup process when the power is turned on, the reference value is changed in a state different from the normal state. In this case, if the reference value is used, the predetermined value may not be reached and the specific output may not be performed, and the occurrence of the specific event cannot be suitably detected. Therefore, in this gaming machine, when the determination unit determines that the adjustment condition is satisfied, an adjustment command is issued to the detection unit and the reference value of the detection unit is changed. Regardless, by setting the adjustment condition to the normal state, for example, it is possible to change the reference value in the normal state, and it is possible to suitably detect the occurrence of a specific event corresponding to an illegal act.

  In particular, when the changing means is configured to change the reference value, the above-described effects can be achieved with a simple configuration as compared with the configuration in which the amplitude of the detected value is changed. Specifically, in order to change the amplitude of the detection value, a configuration (for example, an operational amplifier) for changing the detection value in the detection unit is required. On the other hand, the configuration for changing the reference value can be a simple configuration because it can be performed by a software change of a means (for example, MPU 222) for monitoring the amount of change in the detected value.

Feature A2. It is possible to monitor the state of the gaming machine, and includes control means (main control device 122) capable of executing processing (for example, timer interrupt processing) according to the monitoring result,
The game machine according to Feature A1, wherein the determination unit and the command unit are provided in the control unit.

  According to the feature A2, the control unit that monitors the state of the gaming machine and executes processing according to the monitoring result determines whether or not the adjustment condition is satisfied, and issues an adjustment command. Therefore, in accordance with the state of the gaming machine, for example, by changing the reference value in the detection means when the gaming machine is in a normal state, the reference value is not shifted as described in the feature A1, and the illegal purpose It is possible to suitably detect the occurrence of a specific event corresponding to.

  Feature A3. The adjustment condition is established when a predetermined component (for example, the inner frame 13) of the gaming machine is in a normal state (for example, a closed state) when a game is played by the player. The gaming machine according to feature A1 or feature A2.

  According to the feature A3, the reference value is changed by the changing means when the predetermined component is in a normal state in which a game is played by the player. Therefore, by using the changed reference value, it is possible to suitably detect the occurrence of the specific event without causing a deviation from the reference value in the situation where the game is played by the player.

Feature A4. The game machine main body includes a door body (inner frame 13) that is supported so as to be switchable between an open state and a closed state, and that includes the detection means or is included in the detection range of the detection means.
The gaming machine according to any one of features A1 to A3, wherein the adjustment condition is established under at least one condition that the door is in a closed state.

  According to the feature A4, the adjustment condition is satisfied at least when the door is in the closed state, and the reference value is changed. For example, when the door is opened, vibration may occur as a specific event. In addition, a metal plate or an electric device is generally mounted on the door body. When the door body is in an open state, the detection values of radio waves and magnetism detected in the normal state of the gaming machine may be different. Therefore, as in this configuration, by changing the reference value with the door closed, it is possible to suppress the deviation of the reference value and to suitably detect the occurrence of the specific event.

  Feature A5. The changing means is configured such that after changing the reference value by the adjustment command, the reference value is not changed when the door body is opened and then closed. A gaming machine according to Feature A4, characterized by

  According to the feature A5, after the reference value is changed when the door is closed, the reference value is not changed even if the door is opened and then closed again. For example, in gaming machines, there are cases where the door body is opened and closed for inspection, etc. during gaming, and if the reference value is changed during the inspection, the reference value is frequently changed. Become. Therefore, the period for detecting the occurrence of the specific event is relatively short, which is not preferable. On the other hand, as in this configuration, the reference value is not changed even if the door is opened and closed again after changing the reference value, so that the period for detecting the occurrence of the specific event is relatively long. Thus, it is possible to preferably detect the occurrence of the specific event corresponding to the fraud.

Feature A6. The detection means is provided on the door body,
Further, the gaming machine according to Feature A4 or Feature A5, wherein a switching means capable of switching the power source of the gaming machine between the power-on state and the power-off state is provided on the back surface of the door body.

  According to the feature A6, since the switching means is provided on the back surface of the door body, in order to switch the power supply of the gaming machine from the power-off state to the power-on state by the switching means, the door body is opened. Need arises. Generally, gaming machines are installed in parallel with island facilities, and when the doors of each gaming machine arranged in parallel are opened, the doors of one gaming machine and other gaming machines The distance to the door is shortened. In this situation, since the detection means is provided on the door body, the distance between the detection means provided on the door body of one gaming machine and the door body of the other gaming machine is reduced. In general, the door is equipped with a drive device or the like necessary for the progress of the game, and a specific event can also occur from the drive device. In other words, if the reference value is changed in a state where the distance from the door body of such other gaming machine is close, a specific event from the driving device of the other gaming machine may be taken into account and a deviation may occur. There is sex. On the other hand, according to this configuration, as described in the feature A4, the door is in the closed state, which is a condition for the adjustment condition. Therefore, the power is turned on by the switching unit. However, the reference value is changed after the door body is closed, and it is possible to suppress the deviation of the concerned reference value and to appropriately detect the occurrence of the specific event corresponding to the unauthorized purpose. .

Feature A7. The adjustment process for changing the reference value by the changing means is performed over a predetermined period,
The game according to any one of features A1 to A6, wherein the detection means executes an output that enables the corresponding process execution means to specify the occurrence of the specific event even during the predetermined period. Machine.

  According to feature A7, the response processing execution unit can specify the occurrence of the specific event even during the predetermined period in which the changing unit is changing the reference value, and the specific event corresponding to the fraudulent purpose can be specified even during the predetermined period. It is possible to carry out treatment in the case of occurrence of

Feature A8. The changing means is configured to start adjustment for changing the reference value according to the adjustment command, and when the adjustment is not completed, information to that effect is output from the detecting means,
When the instruction means receives the information to that effect, the instruction means again performs the adjustment instruction to the detection means when the determination means determines again that the adjustment condition is satisfied. The gaming machine according to any one of features A1 to A7, wherein:

  According to the feature A8, when the adjustment of the reference value change by the adjustment command is not completed, the adjustment of the reference value change can be started when the adjustment condition is satisfied again. For example, when the adjustment for changing the reference value is not completed, the adjustment may be automatically started again in a state where the adjustment condition is not satisfied. In this case, since the adjustment condition is not satisfied, there is a concern that the reference value may be shifted as described above. On the other hand, according to this configuration, since the adjustment is started when the adjustment condition is satisfied again, it is possible to suppress the occurrence of the inconvenience described above.

  Feature A9. The gaming machine according to any one of features A1 to A8, wherein the changing means is configured to change the reference value without being based on the adjustment command when operating power is supplied.

  According to the feature A9, the changing means changes the reference value when operating power is supplied and when an adjustment command is received. For example, if the reference value is changed only when an adjustment command is received, an illegal act is assumed in which the adjustment condition is satisfied at an intended timing so that the adjustment condition is not satisfied. In this case, if a specific event is generated during the adjustment of the reference value and the reference value is shifted and changed, the specific output is not generated even if the specific event is subsequently generated, and the illegal act may not be specified. The specific event corresponding to the fraudulent act is assumed to have a larger fluctuation in the detected value than the specific event due to the environment around the gaming machine. According to this configuration, when a fraudulent act that does not satisfy the adjustment condition is made Even in such a case, since the reference value is changed at least when operating power is supplied, it is possible to specify at least a specific event corresponding to an illegal act using the changed reference value.

Feature A10. Drive means (for example, game ball launching mechanism 40) that performs initial drive when operating power is supplied,
The change unit is configured to change the reference value by the adjustment command after the initial drive by the drive unit is performed. Any one of features A1 to A9, wherein: Game machines.

  According to the feature A10, it is possible to change the reference value without taking into account a specific event generated by the initial driving of the driving unit. Since the specific event due to the initial drive is specific when the power is turned on, if the reference value is changed in consideration of the specific event, the difference between the state where the occurrence of the specific event corresponding to the unauthorized purpose should be detected and the reference value Will occur. On the other hand, according to this configuration, the reference value can be changed in a state where the occurrence of the specific event corresponding to the fraudulent purpose should be detected, and it is possible to suitably identify the fraudulent act.

Feature A11. The command unit is configured to issue the adjustment command when the determination unit determines that the adjustment condition is satisfied in a situation where the detection unit can perform the specific output.
The detection unit is configured to output an adjustment result to the corresponding process execution unit when the reference value is changed,
The gaming machine according to any one of features A1 to A10, wherein the response processing execution unit is configured to be able to distinguish between the specific output and the output of the adjustment result.

  According to the feature A11, since the specific output corresponding to the occurrence of the specific event is distinguished from the output corresponding to the information of the adjustment result, the response processing execution unit specifies the occurrence of the specific event while specifying the occurrence of the specific event. The adjustment result can be specified. Therefore, even if the timing at which the occurrence of a specific event corresponding to fraud is to be identified and the timing at which the reference value is changed overlap, separate response processing should be performed based on the respective information Is possible.

  The process corresponding to each information may be, for example, a process for performing notification by a notification means provided in a gaming machine or a process for stopping control related to the progress of a game when an illegal act is specified. When the adjustment result of the reference value is specified, for example, a process for performing the adjustment again based on the adjustment result or a process for notifying the adjustment result can be considered.

  Feature A12. The gaming machine according to any one of features A1 to A11, wherein the detection means detects magnetism as the specific event.

  According to the feature A12, the magnetism improperly applied can be detected, and the above-described excellent effect can be achieved.

  In general, a gaming machine is provided with an opening through which a game ball can enter, and a privilege is given based on the game ball entering the opening. Further, when a game ball enters a predetermined opening, it is determined whether or not to shift to an advantageous state advantageous to the player. Therefore, there is a concern about an unauthorized act of guiding the game ball to these openings using magnetism. Therefore, the detection means can detect the magnetism to suppress the illegal act.

  On the other hand, game machines are equipped with various drive devices, and magnetism is also generated when these drive devices are driven. Further, depending on the environment of the game hall, for example, in a game hall under an overhead, the geomagnetism can affect the detection value of the detection means. The magnetism generated by these driving devices and the geomagnetism due to the environment of the game hall can be said to be magnetism that can be detected by the detection means while the game is in progress. Therefore, by changing the reference value in consideration of these magnetisms, it is possible to suitably detect the magnetism corresponding to the fraudulent act while excluding the magnetism that can be detected by the detection means even during the game. .

  However, when the gaming machine is turned on, various driving devices are initially driven as a startup process, and magnetism is also generated by the initial driving. Further, when the power is turned on, the magnetic field is changed by applying voltages to the various driving devices. Unlike the magnetism applied for illegal purposes, the generation of the magnetism and the change of the magnetic field can be said to be peculiar when the power is turned on. Therefore, if the reference value is changed in the start-up process when the power is turned on, the reference value is shifted in consideration of the magnetism and magnetic field change peculiar to the power-on. On the other hand, as described in the feature A1, when the adjustment condition is satisfied, the detection means changes the reference value, thereby eliminating magnetism peculiar to power-on and applying it for an illegal purpose while suppressing false detection. It is possible to suitably detect the magnetism.

Feature A13. The detection value fluctuates when a specific event (for example, magnetism) occurs, and the specific output (detection state signal is output based on the amount of change in the detection value with respect to the reference value (0 value) reaching a predetermined value (threshold value).

With
The detecting means is a changing means (MPU 222 of the magnetic sensor module 81) for changing a relative relationship between the reference value and the detected value (sensitivity specified by 0 value and threshold, or sensitivity specified by amplitude of the detected value).

With
The gaming machine according to claim 1, wherein the changing means changes the relative relationship when the command means issues the adjustment command.

  According to the feature A13, the detection unit can change the relative relationship between the reference value serving as a reference for performing the specific output and the detection value when the adjustment condition is satisfied. Since the detection means is configured to perform a specific output when the amount of change in the detection value with respect to the reference value reaches a predetermined amount, depending on the changed relative relationship, the predetermined value may or may not reach the predetermined value. Sometimes not. Therefore, the relative relationship should be changed on the basis of the normal state of the gaming machine in which a game is played by a player who has a high possibility of fraud. For example, if the configuration is such that the relative relationship is changed by the startup process when the power is turned on, the relative relationship has been changed in a state different from the normal state. In this case, if the relative relationship is used, the detection value may not reach the predetermined value and the specific output may not be performed, and the occurrence of the specific event cannot be suitably detected. Therefore, in this gaming machine, when the determination unit determines that the adjustment condition is satisfied, an adjustment command is issued to the detection unit, and the relative relationship between the reference value of the detection unit and the detection value is changed. Therefore, regardless of the power-on timing, it is possible to change the relative relationship in the normal state by setting the adjustment condition to the normal state, for example, and preferably detect the occurrence of a specific event corresponding to an illegal act Can do.

  The configuration limited in any of the features A1 to A12 may be applied to the feature A13.

<Feature B group>
Feature B1. The detection value fluctuates when a specific event (for example, magnetism) occurs, and the specific output (detection state signal is output based on the amount of change in the detection value with respect to the reference value (0 value) reaching a predetermined value (threshold value). Detecting means (magnetic sensor module 81) for performing switching to the HI level signal;
Corresponding process execution means (magnetic detection in MPU 211 of main control unit 122) that executes corresponding processing (steps S1105 and S1106 in MPU 211 of main control unit 122) based on the detection unit performing the specific output. Function to execute processing)
With
The detection means includes a change means (a function of executing a second adjustment detection process in the MPU 222 of the magnetic sensor module 81) that changes the amplitude (sensitivity coefficient G) of the detection value according to the predetermined value.
Determination means for determining whether or not the adjustment condition is satisfied (function for executing sensor correction processing in the MPU 211 of the main control device 122);
When the determination means determines that the adjustment condition is satisfied, command means (for controlling the main control device 122) performs an amplitude adjustment command (switches the adjustment signal to the HI level signal) to the detection means. The function of executing the processing of step S1011, step S1509 or step S1604 in the MPU 211);
With
The game machine according to claim 1, wherein the changing means changes the amplitude of the detected value in accordance with the predetermined value when the command means issues the adjustment command.

  According to the feature B1, the detection unit can change the amplitude of the detection value serving as a reference for performing the specific output when the adjustment condition is satisfied. Since the detection means is configured to perform a specific output when the amount of change with respect to the reference value reaches a predetermined amount, even when the amplitude of the detection value is changed according to the predetermined value, even a specific event having the same intensity is used. The amount of change in the detected value may change and reach a predetermined value, or may not reach the predetermined value. Therefore, the amplitude of the detected value should be changed on the basis of the normal state of the gaming machine in which a game is played by a player who has a high possibility of fraud. For example, if the configuration is such that the amplitude of the detected value is changed by the startup process when the power is turned on, the amplitude of the detected value is changed in a state different from the normal state. In this case, if the amplitude is used, the predetermined value may not be reached and the specific output may not be performed, and the occurrence of the specific event cannot be suitably detected. Therefore, in this gaming machine, when the determination unit determines that the adjustment condition is satisfied, the adjustment command is issued to the detection unit and the amplitude of the detection value of the detection unit is changed. Regardless of the adjustment condition, for example, by setting the adjustment condition to the normal state, it is possible to change the amplitude of the detection value in the normal state, and it is possible to suitably detect the occurrence of the specific event corresponding to the fraudulent act. .

  In particular, if the changing means is configured to change the amplitude of the detected value, the influence of the strength of a specific event occurring around the gaming machine can be reduced as compared with a configuration in which the reference value is changed. Specifically, when the reference value is changed, if the specific event that occurs around the gaming machine is near the detection limit of the detection means, the detection value is not stable and the reference value cannot be suitably changed. There are concerns about inconvenience. On the other hand, by changing the amplitude of the detection value, the width of the detection limit of the detection means is widened, and the above-mentioned inconvenience can be avoided.

Feature B2. The changing means includes means for changing the reference value according to the detected value (function of executing a second offset process in the MPU 222 of the magnetic sensor module 81),
The game machine according to Feature B1, wherein the changing means changes the amplitude of the detected value after changing the reference value according to the detected value.

  According to the feature B2, the amplitude of the detected value is changed after the reference value is changed according to the detected value by the adjustment command. If the detected value is far from the predetermined value when the amplitude of the detected value is changed, there is a concern that the amplitude needs to be changed repeatedly. Therefore, by adopting a configuration in which the amplitude is changed after changing the reference value, it is possible to suitably change the amplitude while avoiding the above-mentioned inconvenience.

  Feature B3. The change means changes the amplitude of the detection value, and then the detection value based on the changed amplitude has a predetermined condition in relation to the predetermined value (the detection value exceeds the threshold or the detection value falls below the threshold) Is satisfied, the final amplitude is determined based on the amplitude, and if the detected value based on the changed amplitude does not satisfy the predetermined condition in relation to the predetermined value, the amplitude is further changed. The gaming machine according to feature B2, wherein the gaming machine is configured to confirm whether or not a detection value based on the changed amplitude satisfies the predetermined condition in relation to the predetermined value.

  According to the feature B3, the amplitude is changed stepwise. In such a configuration in which the amplitude is changed stepwise, as described in the feature B2, the reference value is changed before the amplitude is changed. Therefore, the detection value based on the amplitude after the change is a predetermined value. Therefore, it is highly possible that the predetermined condition is satisfied, and the process for changing the amplitude can be completed relatively smoothly. Therefore, even if it is difficult to specify the occurrence of a specific event during the process for changing the amplitude, the process proceeds smoothly as described above, so that the occurrence of the specific event can be easily specified. It is possible to appropriately detect the occurrence of a specific event corresponding to an illegal act.

  Feature B4. The predetermined value is set to a value that is larger or smaller than the range of the detected value that can be changed by an internal factor in the state of installation in the game hall (magnetism or magnetism by various control devices). The gaming machine according to any one of features B1 to B3.

  According to the feature B4, when the amplitude of the detection value is changed in correspondence with the predetermined value, it can be performed with only one process of increasing or decreasing the amplitude, and thus can be changed with a simple processing configuration.

  The configuration limited in any of the features A1 to A13 may be applied to any one of the features B1 to B4.
