Description

  The present invention relates to a pachinko gaming machine capable of detecting a winning of a game ball due to an illegal act.

  Many pachinko gaming machines have a proximity switch as a detection switch for detecting the entry of a game ball based on the detection state of the detection switch that is detected by a scheduled interruption process of the main controller. It is configured to confirm the entry of game balls.

  In pachinko machines, various kinds of fraudulent acts are unending, but among them, the radio wave that obtains a prize ball illegally by malfunctioning the detection switch arranged at the prize opening, and the flow path of game balls There has been an increase in fraudulent acts (so-called low-tech goto) using goto equipment during games, such as nail-bending goto and magnet goto (grape goto), which increase the winning rate for a predetermined winning opening by changing.

  For such a situation, fraudulent acts are monitored by providing a frame closing sensor, a radio wave sensor, a magnetic force sensor, etc. in the gaming machine itself or in the vicinity thereof, but the effect is not easily obtained. In particular, for the above-mentioned radio goto, an invention for detecting radio goto by disposing two proximity switches (double sensor) with respect to one winning opening is also disclosed <patent document 1> <patent document 2>.

  However, since Patent Documents 1 and 2 only need to monitor the detection state of one of the switches that should not be detected or are always detected, it is possible to simplify unauthorized monitoring control that performs radio wave irradiation. However, cheating can be performed without difficulty by irradiating only the other detection switch for detecting a game ball with a radio wave locally. In addition, the ROM capacity of the main control device is determined by the rules, and in order to install the anti-fraud program in the main control device, some control programs related to games are not installed. Sometimes had to be sacrificed.

  Therefore, in view of the above problems, the present invention is configured such that two detection switches as W sensors detect the entry of game balls, and the detection determination method of each detection switch is different to perform irradiation of radio waves. An object of the present invention is to provide a ball game machine capable of avoiding a decrease in gameability by reducing a burden on a main control device while making it difficult to perform an illegal act.

It is good also as a switch which detects a game ball by interruption | blocking or a change of magnetic flux.

  The output mode of the first ball detection switch monitored by the main control device by the periodic interrupt process may be a mode indicating a detection state of a game ball or a mode indicating a non-detection state, and is a predetermined setting for setting a first pitch flag Condition 1 may be based on the detection state and non-detection state of the switch signal output by the first sphere detection switch. Further, the output mode of the second ball detection switch monitored by the sub-control device by the periodic interruption process may be a mode indicating the detection state of the game ball or a mode indicating the non-detection state, and the second ball entry flag is set. The predetermined condition 2 may be based on a detection state and a non-detection state of a switch signal output from the second sphere detection switch.

  The “abnormal entry determination means for determining whether or not the entry is abnormal based on the reception of the first entry command and the setting of the second entry flag” is based on the arrangement position of each ball detection switch. It is only necessary to determine whether or not the reception of the incoming ball command and the setting of the second incoming flag are performed, and the downstream side after the upstream first incoming flag is set (received the incoming ball command). Whether or not the second entry flag on the side is set within a predetermined time, or the first entry flag (entrance command) on the downstream side is set within the predetermined time after the second entry flag on the upstream side is set It may be determined whether or not it has been set (received).

In the normally closed type ball detection switch, the output signal changes according to the period of the radio wave due to the influence of the radio wave only when the game ball is detected (Low (0) state). When the sphere is not detected (Low (0) state), the output signal changes according to the period of the radio wave due to the influence of the radio wave.

The ball game machine according to claim 3 is:

  According to the ball game machine of claim 1, the predetermined condition 1 and the predetermined condition 2 are set so that, for example, the continuous number of output modes indicating the game ball detection state is different, so that two radio waves are transmitted. When the detection switch is irradiated, there is an inconsistency that one entry flag setting means sets the entry flag and the other entry flag setting means does not set the entry flag. It can be easily determined that this is not the case. Furthermore, by entering the game ball with the sub-control device, it is possible to reduce the processing load on the main control device and avoid a decrease in game play.

  According to the bullet ball game machine of claim 2, since at least one of them is a normally closed type ball detection switch, the radio wave can only be output when a low signal indicating detection of a game ball is output. The difficulty can be increased.

  According to the bullet ball game machine of claim 3, by adopting a normally open type ball detection switch that outputs a Low signal when the game ball is not detected and a Hi signal when the game ball is detected to the other, The radio wave can be played only when the low signal indicating the non-detection state of the game ball is output, and the radio wave can be acquired only when the low signal indicating the detection state of the game ball is output.

The details are described later.

  Next, a main routine executed by the main controller 50 will be described with reference to FIG. The flowchart shown in FIG. 3 represents a main process executed by the microcomputer of the main controller 50, and is a process periodically executed by a hardware interrupt every about 2 mS. In the present embodiment, each process from S10 to S70 is a process that is executed only once in the interrupt process and is referred to as “main process”, and is repeated as long as time permits within the remaining time after executing this main process. The executed processes of S75 and S80 are referred to as “residual process”.

  When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (S10). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. It is for judging whether it is okay. If the interrupt is not normal, microcomputer runaway due to noise or the like may be considered when power is turned on. However, microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually when power is turned on. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value.

  If it is determined that the interrupt is not normal (S10: no), the initial value is written to the work area of the memory such as a special symbol for writing a predetermined value in the predetermined region of the memory and a normal symbol as an initial symbol. The setting is made (S13), and the process proceeds to the remaining process.

  When an affirmative determination is made as a normal interrupt (S10: yes), update processing for various random numbers is sequentially performed. First, update processing of the initial value random number 1 is executed (S15). This process is an increment process that increments the value of the initial value random number 1 every time this process is executed. The process increments the value of the initial value random number 1 before execution of this process by one, but the random number before this process is executed is increased. When the numerical value is “3966” which is the maximum value, the initial value is returned to “0” in the next processing, and 3967 integers from “0” to “3966” are repeatedly generated in ascending order.

  After the process of S15, an update process of the initial value random number 2 is executed (S20). This process is an increment process that increments the value of the initial random number 2 by 1 for each execution, as in the process of S15. The difference is that the maximum value of the initial value random number 1 is “3966” while the maximum value of the initial value random number 2 is “997”. Therefore, when the random value of the initial value random number 2 before executing this process is “997” which is the maximum value, the initial value is returned to “0” in the next process. The initial value random number 1 is used for big hit determination (special symbol lottery), and the initial value random number 2 is used for hit determination (normal symbol lottery).

  The big hit determination random number update process (S25) subsequent to S20 is an increment process that increments by one each time the process is executed, similar to the update process of the initial value random number 1 and the initial value random number 2, but the maximum value “3966”. In the next process, the initial value random number 1 at that time is set as an initial value (hereinafter referred to as “update initial value”), and the process of incrementing by +1 for each interrupt is further continued. When the value reaches 1 less (hereinafter referred to as “update maximum value”), in the next processing, the initial value random number 1 at that time is set as the initial value, and 3967 adjustments from “0” to “3966” are performed. Create a number repeatedly.

  In other words, +1 is added for each interrupt process, and setting the elements constituting the random number to an integer value from “0” to “3966” is not different from the initial value random number 1, but reaches the updated maximum value of this time. For example, in the next interrupt process, the update initial value at that time is set as an initial value and incremented by +1 for each interrupt until the maximum update value is reached, and the next update initial value is set as the initial value. As a result, the big hit determination random number is set to 3967 integer values from “0” to “3966” as elements constituting the random number, and is incremented by +1 for each interrupt process. Then, since it is changed to a value determined by the initial value random number 1 at that time, the value of the random number can be made unpredictable. In addition, the constituent element of the random number determined by the update initial value and the update maximum value is the same as the conventional random number of random numbers and does not change from 3967 integer values of “0” to “3966”, so that the constituent elements of the random number The appearance rate is made uniform.

  The number of winning values in the normal probability state is 10, and the values are “775” to “777”, “1775” to “1777”, “2774” to “2777”, and the winning values in the high probability state The number is 100 and the values are “775” to “777”, “1314” to “1333”, “1758” to “1777”, “2758” to “2777”, “3314” to “3333”. The hit determination random number update process (S30) subsequent to S25 is an increment process that is incremented by 1 each time the process is executed, similar to the update process of the initial value random number 1 and the initial value random number 2, but “996” that is the maximum value. In the next processing, the initial value random number 2 at that time is set as an initial value (hereinafter referred to as “update initial value”), and the process of incrementing by +1 for each interrupt is further continued. If the value is 1 ”less (hereinafter referred to as“ update maximum value ”), in the next processing, the initial value random number 2 at that time is set as an initial value, and 997 integers from“ 0 ”to“ 996 ”are set. Create a number repeatedly.

  In other words, +1 is added for each interrupt process, and setting the elements constituting the random number to an integer value from “0” to “996” is not different from the initial value random number 2, but reaches the updated maximum value of this time. For example, in the next interrupt process, the update initial value at that time is set as an initial value and incremented by +1 for each interrupt until the maximum update value is reached, and the next update initial value is set as the initial value. As a result, the random number for hit determination is set to 997 integer values from “0” to “996” as elements constituting the random number, and is incremented by +1 for each interrupt process. Then, since it is changed to a value determined by the initial value random number 1 at that time, the value of the random number can be made unpredictable. In addition, the constituent elements of the random number determined by the update initial value and the update maximum value are the same as 997 integer values of “0” to “996” that are the same as the conventional pass / fail random numbers, and thus the elements constituting the random numbers The appearance rate is made uniform. The number of winning values in the normal probability state is 10, and the values are “31” to “40”. The number of winning values in the high probability state is 966, and the values are “31” to “996”. is there.

  The jackpot symbol determination random number update process (S35) is configured as a counter that repeatedly creates 20 integers from “0” to “19”, and is incremented by 1 every time this process exceeds the maximum value, which is the initial value “0”. In this configuration, one big hit symbol is determined from the 20 types of big hit symbols based on the 20 random numbers, and the same big hit symbol is used for both the first special symbol and the second special symbol. .

  The probability of being determined to be a big win in the big hit lottery performed due to winning the first start opening 31 (whether or not to generate a special gaming state advantageous to the player) and the second start opening 32 The probability of being determined to be a big hit in the big win lottery performed due to winning a prize is 1 / 396.7 in the normal gaming state and 1 / 39.67 in the high probability gaming state. The number of winning balls during the big hit game is greater when the content of the big hit game entered the first starting port 31 and the big hit hit than when entering the second starting port 32 The probability of getting a big hit is high. Note that the probability of a probable big hit does not change between when the ball enters the first starting port 31 and the lottery is performed and when the lottery is performed after entering the second starting port 32 (with the same probability). is there).

  The small-hit symbol determination random number update process (S40) is configured as a counter that repeatedly creates ten integers “0” to “9”, and is incremented by +1 for each process and is an initial value when the maximum value is exceeded. Return to "0". There are two types of symbols indicating the small hits, and a symbol indicating which small hit is selected is determined by the random numbers for determining the small hit symbols. The symbol indicating the small hit is the same for both the first special symbol and the second special symbol. In addition, the special symbol indicating the loss is the same in the first special symbol and the second special symbol, and the symbol indicating the loss is one type of “-”, so the random number for determining the off symbol is I do not have. Further, since there is only one type of both the winning symbol and the losing symbol of the normal symbol, no random number for determining the winning symbol or the losing symbol is provided.

  The reach determination random number update process (S45) is configured as a counter that repeatedly generates 229 integers from “0” to “228”, and is incremented by +1 every time this process exceeds the maximum value, which is the initial value “0”. Return. In the normal probability state, the number of values to be won when the variable time shortening function is not activated is 21 and the values are “0” to “20”. The value to be won when the variable time shortening function is activated in the normal probability state. The number of is 5 and the value is “0” to “4”, the number of values to be won in the high probability state is 6, and the value is “0” to “5”.

  The variation pattern determination random number update process (S50) is configured as a counter that repeatedly creates 1021 integers from “0” to “1020”, and is incremented by 1 for each process and is the initial value when the maximum value is exceeded. Return to "0". Note that the big hit determination random number, the big hit symbol determination random number, the small hit symbol determination random number, the reach determination random number, and the variation pattern determination random number are awarded to the first starting port 31 or the second starting port 32 (first The start opening switch 31a or the second start switch 32a detects the game ball and determines that it is a win, and the random number for winning determination is passed through the normal symbol operation gate 42 (the normal symbol operation switch 42a is the game ball). Is detected and determined as a prize).

  In the subsequent winning confirmation process (S55), it is determined whether or not the game ball has properly entered each winning opening provided in the game area 26 and whether or not the game ball has normally passed through the normal symbol operating gate 42. It is processing to do. Although the details of the determination will be described later, when it is determined that the game ball is a regular winning in this winning confirmation process, a winning ball is paid out based on winning in each winning mouth (sending a winning ball command to the payout control device 51). , Etc. are implemented.

  Subsequently, a special figure win / fail judgment process (S60) as condition establishment judgment means for judging whether or not a big hit is made, and a normal figure win / fail judgment process (S65) for judging whether or not a normal symbol lottery is won. When the special figure success / failure determination process (S60) and the universal figure success / failure determination process (S65) are finished, each output process (S70) such as an image output process is executed.

  In each output process (S70), each of the effect symbol control device 54a, the payout control device 51, the launch control device, the sub-integrated control device 53, the big prize opening solenoid, the general electric utility solenoid, etc., according to the progress of the game. Execute output processing. That is, when it is confirmed by the winning confirmation process (S55) that a game ball has won at each winning opening provided on the game board 8, the payout control device 51 receives the winning ball data ( The process of outputting a prize ball command) is executed to output an error signal to the effect symbol control device 54a, the hall computer, etc. to notify that an error is occurring when there is an abnormality in the gaming machine.

  The remaining process subsequent to this process is composed of an update process of the initial random number 1 (S75) and an update process of the initial random number 2 (S80), which are exactly the same as the processes of S15 and S20 described above. is there. This process forms an infinite loop and is repeated as long as time permits until the next interrupt is executed. The time required to execute this processing from S10 to S70 described above is whether or not to execute the jackpot processing (execution of special game), or the difference in display mode of the special symbol (first or second) It depends on each interrupt. As a result, the number of times the remaining process is executed is different for each interrupt, and the updated values (added values) of the initial value random number 1 and the initial value random number 2 are not uniform when the interrupt process is executed once. Accordingly, there is no possibility that the initial value random number 1 is synchronized with the big hit determination random number and the initial value random number 2 is synchronized with the hit determination random number. In the present embodiment, the update of the big hit determination random number is changed by the value of the initial value random number 1, and the hit determination random number is changed by the value of the initial value random number 2, so there is no possibility of synchronization.

  Next, using the cross-sectional view of the left general winning opening 35a shown in FIG. 4, according to the present invention, the “ball path for taking the game ball that has entered the ball entrance into the back side of the game board and the ball path The configuration of the first sphere detection switch provided and the second sphere detection switch provided either upstream or downstream of the first sphere detection switch will be described. In the present embodiment, the configurations of the right general winning award port 35a, the right 1 general winning award port switch 35d, and the right 2 general winning award port 35e also correspond to the configuration of the present invention, but have the same configuration as the left general award winning port 35a. Because there is, explanation is omitted.

  In the cross-sectional view of the left general winning opening 35a (corresponding to the entrance of the present invention) shown in FIG. 4 (1), the left side of the figure is the front side of the game board and the right side is the back side. In this embodiment, when a game ball enters the left general winning opening 35a provided in the game area, the ball 1 flows down the ball passage and is guided to the back side of the game board, and then the left 1 connected to the main controller 50 It passes through the passage hole of the general winning opening switch 35b (hereinafter, left 1 switch 35b) and then passes through the passage hole of the left 2 general winning opening switch 35c (hereinafter, left 2 switch 35c) connected to the sub integrated control device 53. It has a configuration. In addition, the structure which arrange | positions each passage hole in the surface side of a game board, the passage hole of the left 1 switch 35b is arrange | positioned in the surface side of a game board, and the passage hole of the left 2 switch 35c is arrange | positioned in the back side of a game board. Configuration is also conceivable.

  FIG. 4 (2) is a view showing a preferred switch arrangement position in the configuration in which the left 1 switch 35b is arranged on the upper side and the left 2 switch 35c is arranged on the lower side. The position of the game ball A indicates the upper end position of the detectable range by the left 1 switch 35b in the figure. The position of the game ball B indicates the lower end position of the detectable range by the left 1 switch 35b in the figure, and the position of the game ball C indicates the upper end position of the detectable range by the left 2 switch 35c in the figure.

  The distance (20.0) necessary to prevent mutual interference between the switches shown in the figure is the case where the two detection switches are arranged closest to each other. The arrangement configuration is such that the detection switch has the smallest arrangement space, and the space on the limited game board surface and the back of the game board can be used efficiently. In addition, the above-described detectable range refers to a position (B) where the game ball is moved downward by the detection distance from the upper limit position (A) of the range in which the game ball is always detected when the game ball flows down from the top. ) Means the range up to.

  In this example, the time for the game ball to flow down the detectable range of 13.4 m between AB is approximately 10 to 14 ms and an average of 12 ms, and the time for the game ball to flow down the 20.1 m interval between AC (left 1 The time difference from the start of the detection of the game ball by the switch 35b to the start of the detection of the game ball by the left 2 switch 35c is approximately 15 to 21 ms, which is an average of 18 ms.

  Next, referring to the timing chart of FIG. 5, when a game ball enters the left general winning opening 35a, the entrance determination timing of the left 1 switch 35b (the left 1 entrance flag setting) executed by the main controller 50 Timing) will be described.

  (1) indicates that when the left 1 switch 35b (NC) arranged on the upstream side and connected to the main controller 50 detects a game ball, the left 1 entrance flag (the first of the present invention) It is a timing chart which showed the timing which sets a 1 entry ball flag). Since the NC type switch signal is inverted and input to the main controller 50 from the detection switch, the signal content received by the main controller 50 is Hi (1) in the game ball detection state, and is not detected. The state is Low (0) (same as NO type).

  The left 1 switch 35b (NC), which is an NC type proximity switch arranged on the upstream side, detects the game ball in the non-detection state Hi (1) of the game ball, and the SW signal changes to the detection state Low (0). Then, since the interval of the scheduled interruption process of the main controller 50 is 2 ms, the change to the detection state is detected within 2 ms from the change of the SW signal. The entrance determination of the left 1 switch 35b executed by the main controller 50 is as follows: “It is detected that the switch signal has changed from the non-detection state Hi (1) to the detection state Low (0) by the scheduled interruption process, and further 3 At the time when it is detected that the SW signal has maintained the detection state Low (0) in the continuous interrupt processing for the first time, it is determined that a game ball has entered, and the left 1 entry flag is set. Therefore, the content in “” corresponds to the predetermined condition 1 of the present invention.

  Next, referring to the figure below, the configuration of the switch data buffer provided in the main controller 50 for executing the above-mentioned entry determination of the left 1 switch 35b, and the switch data pattern (switch data detection for performing the entry determination) Pattern). The switch data buffer temporarily stores a non-detection state “0” or a detection state “1” of a proximity switch arranged at a winning opening that is detected every time the main control device 50 performs a scheduled interruption process, for a predetermined period. It becomes an area.

  Specifically, the switch data buffer is configured by an 8-bit storage area, and is configured to write and update new data from the lower level while shifting the previously stored switch data to the upper level for each scheduled interrupt process. However, a configuration in which data is written from the upper level is also conceivable. In addition, a configuration in which a storage area or a counter for storing data that disappears from the storage area by a shift process when writing new data for a predetermined period is provided, or a configuration in which the switch data buffer is 16 bits can be considered.

  In the switch data buffer of the left 1 switch 35b, as shown by the thick frames in (1) and (a), after the lower 5 bits change from the non-detection state “0” to the detection state “1”, the detection state “1” becomes 3 When the switch data detection pattern “01111” indicating the state maintained once has been reached, it is determined that the player has entered a ball, and the winning confirmation described with reference to FIG. It is the structure which performs a process.

  Next, the left one-switch entry determination process 1 executed by the main controller 50 in this embodiment will be described with reference to the flowchart of FIG. This left 1 switch entry determination process 1 corresponds to the first entry flag setting means of the present invention, and the first entry command is sent to the sub-control device on condition that the first entry flag is set. The process includes an output means for outputting.

  When the left 1 switch entry determination process 1 is started, it is determined whether or not the switch signal of the left 1 switch 35b detected by the scheduled interruption process is “1” (S100). If the determination is affirmative (S100: yes), as the shift processing of the switch data buffer, the oldest stored content is erased and the storage location of the remaining stored content is incremented by 1 bit (S105). Is written (S110). Next, it is determined whether or not the lower 5-bit switch data pattern updated by the processes of S105 and S110 matches “01111” stored in the data table as a pattern for performing the entry process of the left 1 switch 35b. (S115). If the determination is negative (S115: no), the process returns. If the determination is affirmative (S115: yes), as the winning process, an input edge process is performed to write “1” to the corresponding bit position in the winning confirmation buffer (S120). 1 is set to the left 1 entry flag (S125), a (left) entry command is transmitted to the sub-integrated control device 53 (S130), and the process returns. S130 corresponds to the output means of the present invention.

  If S100 is negative (S100: no), as the switch buffer shift processing similar to S105, the oldest stored content is erased and the storage location of the remaining stored content is incremented by 1 bit (S135). “0” is written in the first bit (S140) and the process returns.

  Next, referring to the timing chart of FIG. 7, when a game ball enters the left general winning opening 35a, the entry determination timing (left 2 entry flag) of the left 2 switch 35c executed by the sub-integrated control device 53 is used. Setting timing) will be described.

  (1) indicates that when the left 2 switch 35c (NC) arranged on the downstream side and connected to the sub integrated control device 53 detects a game ball, the left 2 entrance flag (in the present invention) It is a timing chart which showed the timing which sets a 2nd entrance flag).

  The left 2 switch 35c (NC), which is an NC type proximity switch arranged on the downstream side, detects the game ball in the non-detection state Hi (1) of the game ball, and the SW signal changes to the detection state Low (0). Then, since the interval of the scheduled interrupt processing of the sub integrated control device 53 is also 2 ms, the change to the detection state is detected within 2 ms from the change of the SW signal. The entry determination of the left two switch 35c executed by the sub-integrated control device 53 is as follows: “It is detected that the switch signal has changed from the non-detection state Hi (1) to the detection state Low (0) by the scheduled interruption process, When it is detected that the SW signal has maintained the detection state Low (0) in the next scheduled interruption process, it is determined that a game ball has entered, and the left 2 entry flag is set. Therefore, the content in “” corresponds to the predetermined condition 2 of the present invention, and the predetermined condition 1 and the predetermined condition 2 are different contents (the detection state is maintained three times and once).

  Next, referring to the figure below, the configuration of the switch data buffer provided in the sub-integrated control device 53 for executing the entry determination of the left two switch 35c described above, and the switch data pattern (switch data for performing the entry determination) Detection pattern) will be described. The switch data buffer for the left 2 switch 35c stores a non-detection state “0” or a detection state “1” of the left 2 switch 35c, which is detected every time the sub-integrated control device 53 performs a scheduled interrupt process, for a predetermined period. It becomes a temporary storage area.

  Specifically, the switch data buffer included in the sub-integrated control device 53 is also configured by an 8-bit storage area, and new data is written and updated from the lower level while shifting previously stored switch data to the upper level for each scheduled interrupt process. It has a configuration. However, a configuration in which data is written from the upper level is also conceivable. In addition, a configuration in which a storage area or a counter for storing data that disappears from the storage area by a shift process when writing new data for a predetermined period is provided, or a configuration in which the switch data buffer is 16 bits can be considered.

  In the switch data buffer of the left 2 switch 35c, (1) As shown in the thick frame of (a), the lower 3 bits change from the non-detection state “0” to the detection state “1” and the detection state “1” is set to 1. When the switch data detection pattern “011” indicating the state maintained twice is reached, it is determined that the ball has entered, and a ball entry process for setting a left 2 ball entry flag is performed.

  Next, the left two-switch entry determination process 1 executed by the sub integrated control device 53 in this embodiment will be described with reference to the flowchart of FIG. This left two-switch entry determination process 1 is a process corresponding to the second entry flag setting means of the present invention.

  When the left 2 switch entry determination process 1 is started, it is determined whether or not the switch signal of the left 2 switch 35c detected by the scheduled interruption process of the sub integrated control device 53 is “1” (S150). If the determination is affirmative (S150: yes), as the shift process of the switch data buffer, the oldest stored content is deleted and the storage position of the remaining stored content is incremented by 1 bit (S155). Is written (S160). Next, the switch data pattern of the lower 3 bits updated by the processes of S155 and S160 is “011” stored in the data table included in the sub-integrated control device 53 as a pattern for performing the entry process of the left 2 switch 35c. It is determined whether or not they match (S165). If the determination is negative (S165: no), the process returns. If the determination is affirmative (S165: yes), 1 is set in the left 2 entrance flag as an entry process (S170), and the process returns.

  If S150 is negative (S150: no), as the switch buffer shift processing similar to S155, the oldest stored content is erased and the storage location of the remaining stored content is incremented by 1 bit (S175). “0” is written in the first bit (S180), and the process returns.

  Next, in the present embodiment, the sub-integrated control device 53 executes the entrance determination for monitoring the entrance status of the game ball based on the receipt of the entrance command from the main control device 50 and the setting of the left 2 entrance flag. Process 1 will be described using the flowchart of FIG. This entry determination process 1 is a process corresponding to the abnormal entry determination means of the present invention.

  When the entrance determination process 1 is started, it is determined whether or not the timer flag is 0 (S200). The timer flag is a value stored in the sub-integrated control device 53. When the value is “0”, the timer that starts counting every time a (left) entry command is received from the main control device 50 is not activated. If the value is “1”, it is a value for the sub integrated control device 53 to determine that the timer is operating.

  If S200 is affirmative (200: yes), it is determined whether a (left) entry command has been received, that is, whether the left entry flag is set in the main controller 50 (S205). If the determination is affirmative (S205: yes), the timer flag is set to 1 (S210), the initial value of the counter is set by the timer setting process, and the counter is decremented for each scheduled interrupt process (S215), (left ) Increment processing to increment the counter according to the number of times of receiving the incoming command is performed (S220), and return. If S205 is negative (S205: no), it is determined whether the left two-entry flag is 0 (S225).

  If S225 is affirmative (S225: yes), it returns as a normal state, but if it is negative (S225: no), that is, a ball entry command indicating a ball entry to the left 1 switch 35b arranged upstream (left) Although the left 2 entrance flag indicating the entrance to the left 2 switch 35c arranged downstream is set even though the game ball has not been received, radio waves are transmitted to both detection switches when the game ball enters. Since it is determined that only the left 2 switch 35c that has been irradiated and the entry determination condition is unsatisfactory (the number of times of detection state maintenance for performing the entry determination is small) is determined to be the entry determination, error 1 notification for informing the radio wave goto (S230). The implementation status of the radio wave will be described later with reference to the timing chart of FIG.

  When the error 1 notification is implemented, a mode for notifying error 1 is displayed on the effect symbol display device 54b, and the blinking of the error 1 mode is repeated with various lamps / LEDs, and a sound effect indicating the error 1 is output from the speaker. To do. The error 1 notification state ends when the hall staff operates the error release switch 76 disposed on the back of the gaming machine. When the error 1 is canceled, each count value, each timer, and each count related to the entrance determination are cleared (initial state). The error 1 state may be configured to end when a predetermined time (for example, 30 seconds) elapses from the start of notification.

  If S200 is negative, that is, (left) if the timer is operating in response to the reception of the incoming ball command (S200: no), the decrement process is decremented by 1 from the timer that counts every scheduled interrupt process (S235). Further, it is determined whether or not (left) a ball entry command has been received (S240). If an affirmative determination is made (S240: yes), (left) an increment process is performed to increment the counter according to the number of incoming ball commands received (S245), and the counter value is greater than a predetermined value (3 in this embodiment). If it is negative (S250: no), the process proceeds to S260. If the determination is affirmative, that is, if there are a number of game balls that cannot physically exist between the two detection switches of the left 1 switch 35b and the left 2 switch 35c (S250: yes), Since there is a high possibility that clogging has occurred between the detection switches and chattering has occurred in the upstream left 1 switch 35b, error 2 notification is performed (S255).

  When the error 2 notification is performed, as in the case of the error 1 notification, the effect symbol display device 54b displays a mode for reporting the error 2, and repeatedly blinks the error 2 mode with various lamps / LEDs. A sound effect indicating error 2 is output. The error 2 notification state is ended by operating the error release switch 76 disposed on the back of the gaming machine in a state where the hall staff has released the clogging. When the error 2 is canceled, each count value, each timer, and each count related to the entrance determination are cleared (initial state). The error 2 state may be configured to end when a predetermined time (for example, 30 seconds) elapses from the start of notification.

  If S240 or S250 is negative (S240: no, S250: no), it is determined whether or not the left 2 entry flag is 1 (S260). If the determination is affirmative (S260: yes), the counter is decremented by -1 (S265). If the counter is 0, that is, the game ball detected by the upstream left 1 switch 35b is the downstream left 2 switch. It is determined whether or not all are detected in 35c (S270). If the determination is affirmative (S270: yes), the timer is cleared because all the game balls detected by the left 1 switch 35b are normally detected by the left 2 switch 35c (S275), and the timer flag is set to 0. (S280) and return.

  If S260 is negative or S270 is negative (S260: no, S270: no), it is determined whether the counter value of the timer is 0 (S285). If the determination is negative (S285: no), the process returns. If the determination is affirmative, that is, (left) a state where the left two entry flag is not set even after a predetermined time (100 ms in this embodiment) has elapsed since the receipt of the entry command. If so (S285yes), it can be determined that there is a high possibility that a ball clogging has occurred between the left 1 switch 35b and the left 2 switch 35c, so error 2 notification is performed (S290).

  Next, specific examples of the setting timing of each entrance flag and the determination timing of the radio wave when the left 1 switch 35b and the left 2 switch 35c are irradiated with radio waves will be described with reference to FIGS. FIG. 10 is a timing chart when the left 1 switch 35b and the left 2 switch 35c are irradiated with radio waves having a period of 4 ms when the game ball enters the left general winning opening 35a.

  In the NC type proximity switch used for the left 1 switch 35b and the left 2 switch 35c, the SW signal changes under the influence of the irradiated radio wave only during the detection state Low (0) of the game ball. Specifically, the low (0) state is normally maintained during the game ball detection period of 12 ms, and the signal “1” inverted as the switch signal is continuously repeated six times in the scheduled interrupt processing executed by the main controller 50. In this period, as shown in the figure, if a radio wave that repeats Low and Hi is irradiated every 4 ms, the signal in the Low state is raised every 4 ms in accordance with the period of the radio wave, and the signal is raised. In the regular interrupt processing for a certain period, “1” is read as the SW signal.

  In the configuration of this embodiment, when the left 1 switch 35b disposed on the upstream side and the left 2 switch 35c disposed on the downstream side detect the game balls in order from the upstream (the left 1 switch 35b detects the game ball). When the left 2 switch 35c starts detecting the same game ball 18 ms after the start), when a radio wave having a period of 4 ms is irradiated, the false left 1 switch 35b signal detected by the scheduled interruption process is: The game ball changes from the non-detection state “0” to the detection state “1” according to the incoming game ball, but the detection state “1” until the next scheduled interrupt processing in accordance with the radio wave period of 4 ms. And changes to the non-detection state “0” at the next scheduled interrupt processing. Then, after maintaining the non-detection state “0” once, it changes to the detection state “1”, and after maintaining the detection state “1” once, it changes to the non-detection state, and the game ball detection period of the left 1 switch 35b becomes finish.

  The main controller 50 performs the entry determination (setting the left 1 entry flag) based on the SW signal from the left 1 switch 35b as described with reference to FIG. 5 in the switch data buffer. Only when the switch data pattern is detected. Therefore, when a radio wave having a period of 4 ms is irradiated, it is impossible to detect the detection state “1” four times in succession (the detection state must be maintained for at least 8 m), and the left 1 Even when the switch 35b has actually detected a game ball, no entry determination is made and the left 1 entry flag is not set, so the (left) entry command is transmitted to the sub-integrated control device 53. I will not. Also, since no winning confirmation process is performed, no prize balls are paid out.

  This is because even when a game ball actually enters, if a radio wave (radio wave with a time period less than the time required for the ball entry determination) is irradiated along with the incoming ball, It is a configuration in which the ball determination (setting of the ball entry flag) is not performed, and it can be said that the configuration suffers a disadvantage by executing the radio wave goto.

  Subsequently, in the left 2 switch 35c, detection of the same game ball is started 6 ms after the end of the detection state of the left 1 switch 35b (after the completion of the three scheduled interruption processes). In this case, the sub-integrated control device described with reference to FIG. 7 is caused by the influence of the radio wave having a period of 4 ms that is continuously emitted during the 12 ms period in which the switch signal is in the detection state “1” (Low (0) in the detection state). 53 detects the switch data pattern “011” for performing the entry determination (setting the left 2 entry flag) at least once (may be twice), thereby setting the left 2 entry flag. The

  According to the above-described contents, when a radio wave having a period of 4 ms is irradiated when an actual game ball is detected, the main controller 50 does not set the left 1 entry flag based on the false SW signal from the left 1 switch 35b. The sub integrated control device 53 sets the left 2 entry flag at least once based on the false SW signal from the left 2 switch 35c. Therefore, in a situation where a ball entry command indicating entry into the left 1 switch 35b arranged on the upstream side is not received, a left 2 entry flag indicating entry into the left 2 switch 35c arranged on the downstream side is set. Thus, it is determined that there is a high possibility that the radio wave has been executed, and the error 1 notification is executed at the time (A) when the left two entry flag is set. The execution of the error 1 notification corresponds to S230 that is executed from the negative determination of S225 in the entrance determination process 1 of FIG.

  Next, the case of irradiating radio waves with a period of 8 ms will be described with reference to the timing chart of FIG. Note that the timing at which the left 1 switch 35b and the left 2 switch 35c detect a game ball is the same as in FIG.

  When radio waves are irradiated at the timing shown in the figure when the left 1 switch 35b and left 2 switch 35c are detected, the low (0) state of the radio wave with a period of 8 ms is the period of the actual game ball detection state “1”. , The switch data pattern “01111” is detected once in the entry determination of the left 1 switch 35b, and the switch data pattern “011” is detected once in the entry determination of the left 2 switch 35c. Therefore, the left 1 entry flag and the left 2 entry flag are set once each, and the situation is the same as when one game ball is entered normally, and as a result, it is affected by the radio wave goto. There is no configuration.

  The above is the description of the first embodiment. In the first embodiment, since the two detection switches (the left 1 switch 35b and the left 2 switch 35c) to be monitored are both normally closed proximity switches, the timing affected by the radio wave goto is limited to when a game ball is detected. However, even in such a case, the entry determination condition (left 1 entry flag setting condition) of the detection switch arranged on the upstream side and the detection arranged on the downstream side are configured. It is possible to appropriately determine the execution of the radio wave by making the contents different from the entry determination condition (the left 2 entry flag setting condition) of the switch.

  Further, in this embodiment, the switch data pattern for determining the entry of the left 1 switch 35b arranged on the upstream side and connected to the main controller 50 is longer than the switch data pattern of the left 2 switch 35c arranged on the downstream side. Although the number of bits is used, the reverse configuration is also conceivable. For example, if the switch data pattern for determining the entry of the left 1 switch 35b is “011”, the left 1 entry flag is set when a radio wave is irradiated when the game ball enters, so at least the game ball The payout of prize balls according to the entry is carried out. In this case, since the switch data pattern of the left 2 switch 35c is set to “01111”, the left 2 entry flag is not set even when a game ball enters. Accordingly, when the entry determination condition of the downstream left 2 switch 35c is strict, the entry determination process 1 described in FIG. 9 is configured to perform error 1 notification when S285 is affirmative.

  Next, Example 2 will be described. In this embodiment, the electrical connection is the same as that of the first embodiment, and the components constituting the gaming machine are normal proximity switches of the left 2 switch 35c (right 2 switch 35e) connected to the sub-integrated control device 53. The unexpected change to the open (NO) type is the same as in the first embodiment. Therefore, the overlapping part will be described with reference to the first embodiment.

  In the first embodiment, the left 1 switch 35b and the left 2 switch 35c to be monitored are both normally closed (NC) type, but in this embodiment, the left 2 switch 35c disposed on the downstream side is normally open (NO ) Type configuration.

  1, 2, 3, 4, 5, 6, 8, and 9 described in the first embodiment are common contents, and thus the description is used. The entrance determination timing (left 2 entrance flag setting timing) of the left 2 switch 35c arranged on the side will be described.

  FIG. 12 shows that in this embodiment, when the left 2 switch 35c (NO) disposed downstream and connected to the sub integrated control device 53 detects a game ball, the left 2 entrance flag as a result of the entrance determination It is a timing chart which showed the timing which sets (it corresponds to the 2nd entrance flag of the present invention). As described above, since the left 2 switch 35c is of the NO type in this embodiment, the detection state is Low (0) when the game ball is not detected, the detection state is Hi (1) at the time of detection, and the SW signal has the same content. Is output. Therefore, the NO type has a configuration in which the SW signal is raised to the detection state Hi (1) in accordance with the frequency of the radio wave in the non-detection state Low (0) of the game ball.

  When the NO type left 2 switch 35c arranged on the downstream side detects the game ball in the non-detection state Low (0) of the game ball and the SW signal changes to the detection state Hi (1), the sub integrated control device 53 Since the interval of the scheduled interrupt processing is 2 ms, the change to the detection state is detected within 2 ms from the change of the SW signal. In the entrance determination of the left 2 switch 35c executed by the sub-integrated control device 53, it is detected that the switch signal has changed from the non-detection state Low (0) to the detection state Hi (1) by the scheduled interruption process, and further When it is detected that the SW signal has maintained the detection state Hi (1) in the scheduled interruption process, it is determined that a game ball has entered, and the left 2 entry flag is set. Therefore, the conditions from when the SW signal changes (after rising) until the ball entry flag is set have the same contents as the left two switch 35c arranged on the downstream side in the first embodiment.

  Therefore, when comparing the entrance determination of the game ball between the left 1 switch 35b and the left 2 switch 35c, the left 1 switch 35b is more likely to detect the change of the SW signal before executing the entrance determination. It is necessary to execute a regular interrupt process, which indicates a configuration in which a ball entry determination is performed by confirming the detection state for a longer time than the left two switch 35c.

  Also in this embodiment, the winning confirmation process (S55) is performed when the left 1 entry flag of the NC type left 1 switch 35b arranged on the upstream side is set (when the entry is determined). Thereby, processing related to the progress of the game such as a prize ball is executed based on the SW signal from the NC type switch, which is safer against radio wave goto, and the entrance determination by the SW signal is performed. The configuration is set to a stricter condition. Also in this embodiment, if the same number of first and second entrance flags are established in response to detection of the SW signal output by each switch, it is determined that the normal entry of the normal game ball is normal. .

  The left two-switch entry determination process 2 and the entry determination process 2 executed by the sub-integrated control device 53 in the second embodiment are the same as those in the first embodiment, and are therefore used. Next, FIG. 13 and FIG. With reference to the timing chart, the setting timing of each entry flag and the determination timing of the radio wave when the left 1 switch 35b and the left 2 switch 35c are irradiated with radio waves will be described. FIG. 13 is a timing chart when the left 1 switch 35b and the left 2 switch 35c are irradiated with radio waves having a period of 4 ms when the game ball enters the left general winning opening 35a.

  Even in the configuration of the present embodiment, when the left 1 switch 35b (NC) arranged on the upstream side and the left 2 switch 35c (NO) arranged on the downstream side detect the game balls in order from the upstream side, a cycle of 4 ms (When the left switch 35b detects the same game ball 18ms after the left 1 switch 35b starts detecting the game ball), the main controller 50 detects the false left by the scheduled interruption process. The output signal of the 1 switch 35b changes from the non-detection state “0” of the game ball to the detection state “1” according to the actual game ball entering, but in the period of 12 ms that actually becomes the detection state, irradiation is performed. It will change every 4 ms due to the effect of the radio wave. However, since the data pattern of “01111” for performing the entry determination is not maintained with the radio wave of 4 ms, the left 1 entry flag is not set (the same configuration as in the first embodiment).

  In the left 2 switch 35c arranged on the downstream side, the SW signal in the Low (0) state changes at a cycle of 4 ms by the irradiation of radio waves before actually detecting the game ball, and the sub-integrated control device 53 interrupts at a fixed time. The data pattern “011” is detected by the processing.

  Therefore, in the case of the configuration of the present embodiment, the entry to the left 2SW 35c arranged on the downstream side is made even though the left 1 entry flag indicating the entry to the left 1SW 35b arranged on the upstream side is not set. At the time (B) when the left two entry flag shown is set, it is determined that there is a high possibility that the radio wave has been executed, and error 1 notification is executed. The execution of the error 1 notification also corresponds to S230 executed from the negative determination of S225 in the entry determination processing 1 of FIG.

  Next, the case where the radio wave of 8 ms period is irradiated will be described with reference to the timing chart of FIG. Note that the timing at which the left 1 switch 35b and the left 2 switch 35c detect a game ball is the same as in FIG.

  When radio waves are emitted at the timing shown in the figure when the left 1 switch 35b and the left 2 switch 35c are detected, a switch data pattern of “01111” is detected in the entrance determination of the upstream left 1 switch 35b. When the left 1 entry flag is set, a (left) entry command is transmitted to the sub integrated control device 53. In the entrance determination of the downstream left 2 switch 35c, the switch data pattern “011” is detected before the actual game ball is detected, and the switch data pattern “011” is also detected when the actual game ball is detected. Is detected.

  Therefore, the number of times that the left 1 switch 35c arranged on the downstream side is set to the left 2 switch 35c arranged on the downstream side rather than the set number of times of the left 1 entry flag indicating the entry to the left 1 switch 35b arranged on the upstream side. Since the number of times of setting the left 2 entrance flag indicating the entrance becomes larger, the error 1 notification is executed at the time (C) when the left 2 entrance flag is set extra. However, the determination of the error 1 notification is the same as the error 1 notification of FIG. 13, even though it has not received the (left) entry command indicating the entry to the left 1 SW 35 b arranged on the upstream side, the downstream side Error 1 notification at the time (C) when the left 2 entry flag indicating entry to the left 2SW 35c placed at is set, and in S230 executed from the negative determination of S225 in the entry determination processing 1 of FIG. Applicable.

  The above is the description of the second embodiment. In this embodiment, the left 1 switch 35b disposed on the upstream side is a normally closed type, the left 2 switch 35c disposed on the downstream side is a normally open type, and the entry determination conditions (entrance flag setting conditions) of each switch ) Is different. This makes it possible to further increase the difficulty of cheating by mixing detection switches that enable radio wave goto only when a game ball is detected and detection switches that enable radio goto when no game ball is detected. In addition, the winning confirmation process can be performed with a highly safe detection switch.

  Next, Example 3 will be described. In this embodiment, the electrical connection is the same as in the first and second embodiments, and the parts constituting the gaming machine are the same as those in the second embodiment, while the left 1 switch 35b connected to the main controller 50 (the first embodiment of the present invention). 1 ball detection switch) is arranged on the downstream side of the ball path, and the left two switch 35c connected to the sub integrated control device 53 is arranged on the upstream side. Even in this case, the left 1 switch 35b connected to the main control device 50 is a normally closed type, and the left 2 switch 35 connected to the sub integrated control device 53 is a normally open type.

  1, 2 and 3 described in the first embodiment are the same as the contents of the present embodiment, so the description will be used. The arrangement of the left 1 switch 35b (NC) and the left 2 switch 35c will be described with reference to FIG. .

  In the cross-sectional view of the left general winning opening 35a of the third embodiment shown in FIG. 15, a normal open type left 2 switch 35c connected to the sub integrated control device 53 on the upstream side (corresponding to the second ball detection switch of the present invention). Is arranged, and a normally closed type left 1 switch 35b connected to the main controller 50 is arranged on the downstream side. Therefore, in this embodiment, when the game ball enters the left general winning opening 35a, the left 2 switch 35c connected to the sub integrated control device 53 is configured to detect the game ball first. The arrangement interval between the left 2 switch 35c and the left 1 switch 35b is the same as in the first and second embodiments, and a limited space can be used effectively.

  Switch data pattern for determining the entrance (left 2 entrance flag setting timing) by the left 2 switch 35c arranged on the upstream side and connected to the sub integrated control device 53 and the entrance determination stored in the sub integrated control device 53 Is the same as the content described with reference to FIG. Further, the left two-switch entry determination process 3 executed by the sub-integrated control device 53 in this embodiment is common to the left two-switch entry determination process 1 described with reference to FIG. To do.

  The entrance determination timing (left 1 entrance flag setting timing) by the left 1 switch 35b arranged on the downstream side and connected to the main controller 50, and the switch data pattern for performing entrance determination stored in the main controller 50 are: Since it is the same as the content demonstrated using FIG. 5 in Example 1, it uses it. Further, the left 1 switch entry determination process 3 executed by the main controller 50 in this embodiment is common to the left 1 switch entry determination process 1 described with reference to FIG. .

  Next, in the present embodiment, the sub-integrated control device 53 executes the entrance determination process 3 for monitoring the entrance status of the game ball based on the setting of the left 2 entrance flag and the reception of the (left) entrance command. This will be described with reference to the flowchart of FIG. This entry determination process 3 is also a process corresponding to the abnormal entry determination means of the present invention.

  The processing configuration of the entry determination process 3 is the same as that of the entry determination process 1 except for two locations, and the determination location for error 1 notification is different. The different processing configurations are the processing after the affirmative determination of S435 corresponding to S240 of the entrance determination processing 1 and the processing after the negative determination. Specifically, when S435 is a negative determination (S435: no), The timer decrement process performed in S235 of the determination process 1 is performed. If S435 is affirmative (S435: yes), a timer reset process is performed (S440). The timer reset process ends the count of the timer (set in S415 or S440) that started counting based on the previous setting of the left 1 entry flag, clears the counter value, and then initializes the counter in the same manner as in S415. It is a process to restart from the value.

  Further, the error 1 notification for notifying the radio wave in the present embodiment is executed when S450 is affirmative and when S490 is affirmative. If the specific determination contents of S450 are normal entry determinations, the number of left 2 entry flags set (count value incremented in S420 and S445) and the number of (left) entry commands received (S470). When the situation where only the left two entry flag is set by radio waves (see FIG. 17) occurs, error 1 notification is carried out by this determination.

  The determination in S490 is that the (left) entry command is received once by radio waves (the left 1 entry flag is set once), but if the left 2 entry flag is set more than that, Since it can be determined that there is a high possibility of radio wave gotten when a predetermined time (100 ms in this embodiment) elapses from the time of setting the second left 2 entrance flag, error 1 notification is performed.

  Next, with reference to the timing charts of FIGS. 17 and 18, the setting timing of each entry flag and the determination timing of the radio wave when the left 1 switch 35b and the left 2 switch 35c are irradiated with radio waves will be described. FIG. 17 is a timing chart when the left 2 switch 35c (NO) and the left 1 switch 35b (NC) are irradiated with radio waves having a period of 4 ms when the game ball enters the left general winning opening 35a.

  Even in the configuration of this embodiment, when the left 2 switch 35c (NO) arranged on the upstream side and the left 1 switch 35b (NC) arranged on the downstream side detect the game balls in order from the upstream, When the radio wave is irradiated (the left 1 switch 35b detects the same game ball 18 ms after the left 2 switch 35c starts detecting the game ball), the false left detected by the sub-integrated control device 53 by the scheduled interruption process The output signal of the 1 switch 35b changes from the non-detection state “0” of the game ball to the detection state “1” according to the actual game ball entering, but the SW signal is detected by the game ball detection in the NO type detection switch. Is changed to the detection state “1”, it is not affected by the radio wave, so the detection state “1” is continuously detected during the game ball detection period, and the actual game ball detection period ends. Detection state Low “0” SW signal affected by electric waves from the point at which the changes.

  Therefore, the data pattern of “011” is detected in response to the actual detection of the game ball, the left two-entry flag is set once, and after the game ball detection period ends, the radio wave continuously irradiated is used. When the data pattern “011” is further detected and the second left entry flag is set for the second time, and the radio wave is continuously irradiated, the setting of the left 2 entry flag is also repeated.

  Subsequently, during the 12 ms period when the left switch 35b (NC) connected to the main controller 50 is actually in the detection state, the SW signal changes every 4 ms due to the influence of the irradiated radio wave of 4 ms period. Since the data pattern of “01111” for determining the entrance of the left 1 switch 35b (NC) is not maintained in the radio wave having a period of 4 ms, the left 1 entrance flag is not set, and the sub integrated control device 53 No (left) ball entry command is sent. This can be said that even when a game ball actually enters, if a radio wave is irradiated in accordance with the incoming ball, the incoming ball judgment (setting of the incoming ball flag) according to the incoming ball is not performed. Also, in this embodiment, the winning confirmation process (S55) is performed according to the determination of entering the left 1 switch 35b, so that the payout of the winning ball based on the game ball entering is not performed. This is the same configuration as when the main controller 50 is arranged on the upstream side.

  Therefore, the left 2 entry flag indicating entry into the upstream left 2 switch 35c (NO) is set a plurality of times by irradiation of radio waves, but indicates entry into the downstream left 1 switch 35b ( (Left) No incoming command is received. As a result, when a radio wave having a period of 4 ms is irradiated in the configuration of the present embodiment, a predetermined time (100 ms in the present embodiment) elapses from the time (E) when the left 1 entry flag was last set (left) ) Since no incoming command is received (Yes determination in S450), or when the irradiation of radio waves is continued, the set number of left two incoming flags exceeds a predetermined number (3) (positive determination in S490). It is determined that the probability that Goto has been implemented is high, and error 1 notification is executed.

  Next, the case where the radio wave of 8 ms period is irradiated will be described with reference to the timing chart of FIG. Note that the timing at which the left 2 switch 35c and the left 1 switch 35b detect a game ball is the same as in FIG.

  When the left 2 switch 35c and the left 1 switch 35b detect a game ball when a radio wave having a period of 8 ms is radiated at the timing as shown in the figure, the entrance determination of the upstream left 2 switch 35c determines the actual game ball entrance. The game ball changes from the non-detection state “0” to the detection state “1” in response to the effect of radio waves when the SW signal changes to the detection state “1” by detection of the game ball in the NO type detection switch. Therefore, during the game ball detection period, the detection state “1” is continuously detected, and the actual game ball detection period ends and the non-detection state Low becomes “0”. The SW signal changes.

  Therefore, even when a radio wave having a period of 8 ms is irradiated, the data pattern of “011” is detected in accordance with the actual detection of the game ball, the left two-entry flag is set once, and the game ball detection period ends. A data pattern of “011” is further detected by the radio wave continuously irradiated later, and at this time (F), the second left two-entry flag is set. Subsequently, when the left 1 switch 35b (NC) is irradiated with a radio wave having a period of 8 ms during a period of 12 ms for detecting the game ball, the data pattern “01111” is detected once.

  Therefore, the left 2 entrance flag indicating the entrance to the upstream left 2 switch 35c is set a plurality of times by the irradiation of the radio wave, but the left 1 entrance indicating the entrance to the downstream left 1 switch 35b. The flag is set once. As a result, when a radio wave having a period of 8 ms is irradiated, since the (left) entry command is received once, a predetermined time (in this embodiment, from the time (F) when the left 2 entry flag is set for the second time is received. Even if 100 ms) elapses, (Left) the incoming command is not received, so it is determined that the probability that the radio wave has been executed is high, and error 1 notification is executed.

  The above is the description of the third embodiment. In this embodiment, the left 2 switch 35c disposed on the upstream side is a normally open type, the left 1 switch 35b disposed on the downstream side is a normally closed type, and the entry determination condition (entrance flag setting of the two switches). The conditions are different. Thus, similar to the configuration of the second embodiment, a fraudulent act is performed by mixing a detection switch in which the radio wave is effective only when a game ball is detected and a detection switch in which the radio wave is effective when no game ball is detected. In addition, it is possible to further increase the difficulty level of the game, and to perform a winning confirmation process with a highly safe detection switch.

  The above is the description of the embodiment. In all the embodiments, since at least one of the detection switches to be monitored uses a normally closed type detection switch, a description has been given of a game ball entering when a radio wave is effective as a specific example. When the radio wave is irradiated at times other than when the game ball is entered, in the case of the first embodiment, the two detection switches are both of the normally closed type, so that the SW signal does not change and is not affected by the radio wave.

  In the case of the second embodiment, the normally open left 2 switch 35c arranged on the downstream side is affected, but a (left) entry command indicating entry into the left 1 switch 35b arranged on the upstream side is received. Although the left two-entry flag is set even though it is not, error 1 notification is executed by a negative determination in S225 of FIG.

  In the case of the third embodiment, since the normally open left 2 switch 35c that is arranged on the upstream side and connected to the sub integrated control device 53 is affected and only the left 2 entry flag is set, the left 2 entry flag 16 exceeds the predetermined number, error 1 is notified by the affirmative determination in S450 of FIG. 16, and even if the set number of the left two entry flags does not exceed the predetermined number, an error is determined by the affirmative determination of S490. 1 notification is implemented.

  Therefore, when the left 1 entry flag and the left 2 entry flag are set according to different entry conditions of the left 1 switch 35b and the left 2 switch 35c, respectively, and consistency is obtained by setting one to one within a predetermined time. Since only one of the detection switches is determined to be a normal entry, if only one entry switch is set, only one entry flag is set, so an error 1 notification is always made to notify the radio wave. Execute.

In any of the embodiments, the detection switch used for the determination of winning ball payout (winning confirmation processing) uses a normally closed type that is highly safe against radio waves, and switch data for determining the entering ball. The pattern is set to a stricter condition than the other detection switch. As a result, it is possible to proceed with the game while eliminating fraudulent acts caused by radio waves under more severe conditions. Regardless of the type of switch (normally open or normally closed), the detection switch arranged on the upstream side is connected to the main control device 50, and the detection switch arranged on the downstream side is connected to the sub integrated control device 53. May be. As a result, the detection switch used for the determination of winning ball payout (winning confirmation processing) is on the upstream side, thereby suppressing the occurrence of a time difference between the winning ball and the paying out of the winning ball and playing a game without a sense of incongruity. be able to.
Regardless of the type of switch (normally open or normally closed), the detection switch arranged on the upstream side is connected to the sub-integrated control device 53, and the detection switch arranged on the downstream side is connected to the main control device 50, respectively. May be. Thereby, the structure which pays out a prize ball only for a normal prize-winning can be strengthened by having the detection switch used for determination of prize ball payout (winning confirmation processing) on the downstream side.

  Furthermore, in order to perform the monitoring as described with reference to FIGS. 9 and 16, a sufficient program capacity is required and the time required for processing is also required. In the device 50 and the dispensing control device 51, the load is too heavy. In that respect, the sub integrated control device 53 without any regular performance limitation can sufficiently execute the processing. As a result, not only can the control burden on the main control device 50 be reduced, but the program capacity required as a countermeasure against fraud can be utilized in a direction that enhances the fun of the game, and moreover than the fraud monitoring on the main control device 50. Excellent monitoring can be made possible.

  As described above, according to the ball game machine of the present invention, the fraudulent act of the radio wave is appropriately detected by the entrance monitoring process using the two detection switches (double sensors) by the sub integrated control device 53. However, the capacity of the main control device is not compressed by the fraud monitoring process, and there is no possibility of reducing game play. Therefore, it can be applied to a ball game machine equipped with a sub-control device.
