[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a pachinko machine in which a big winning opening is continuously opened a predetermined number of times as a big win when the numerical value of the big hit counter when the hit ball is won at the start winning opening coincides with a predetermined big hit value. The jackpot value is repeatedly counted from a predetermined initial value to a predetermined value after the end of the control processing performed every predetermined time until the next control processing is started, and the count value at a predetermined timing It is related with the pachinko machine which can prevent specifying the jackpot value from the outside by setting to the jackpot value.
[0002]
[Prior art]
  Conventionally, when a pachinko ball wins a start winning opening, fluctuations displayed on various symbol display devices using a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), etc. provided almost at the center of the game area. After the symbol has started to change and a hit determination has been made and a certain amount of time has passed, in the case of a big win, the symbols are displayed together, and the big winning opening is continuously opened a predetermined number of times as a big win and the jackpot video is displayed on the symbol display device Various types of pachinko machines (first type pachinko machines) have been proposed.
  These pachinko machines are provided with a jackpot counter to make a jackpot determination. This jackpot counter consists of integer values from 0 to N (N is a predetermined positive integer value), and starts from 0 when the power is turned on. Thereafter, 1 is added every predetermined interruption time (for example, every 5 msec or every 10 msec), and when N is reached, the count-up is repeated from 0 again. Next, every time the hit ball wins the start winning opening, the value of the jackpot counter at this time is stored as data for hit determination. Next, if there is no memorization of the hitting ball at the start winning opening at the time of starting the change of the symbol, T1 seconds after the start of the change (for example, 8 seconds or 10 seconds later), and the start winning opening If there is a storage of the winning hit of the hit ball, after T2 seconds (for example, after 5 seconds or after 7 seconds), the hit determination is performed based on the stored value of the jackpot counter.
  At this time, in the case of normal probability (when the probability value of jackpot is 1 / (N + 1)), the numerical value of the hit determination data is M1 (M1 is one integer value of 0 ≦ M1 ≦ N). Therefore, all the values of the jackpot counter other than M1 are out of place.
  Further, in a pachinko machine equipped with a probability variation function, the numerical values of the hit determination data during probability variation (for example, when the jackpot probability value is 7 / (N + 1)) are M1, M2, M3, and M4. , M5, M6, M7 (M1, M2, M3, M4, M5, M6, M7 are different integer values of 0 or more and N or less) and other than M1, M2, M3, M4, M5, M6, and M7 All of the jackpot counter numbers are out of place.
  Thereby, since it is a big hit with a fixed probability at the time of the normal probability, it becomes possible to attract the player's interest in the big hit of the pachinko game and to make it interesting. In addition, the game progresses more and more favorably for the player during the probability fluctuation, so that the interest in the pachinko game can be further increased.
[0003]
[Problems to be solved by the invention]
  However, in the pachinko machine, the value of the jackpot counter coincides with the value M1 of the hit determination data at the normal probability every (N + 1) times, so that the one-chip microcomputer incorporating the ROM and RAM and several electronic components The retrofit board configured by the above is illegally attached to the control board of the pachinko machine, and the retrofit board detects a period counted by the jackpot counter by monitoring a specific control signal of the control board, and the period When the count value of this one-chip microcomputer coincides with the numerical value M1 of the hit determination data, the signal that won the start prize opening is input from the one-chip microcomputer to the control board. There is a problem that it is possible to generate a jackpot.
[0004]
  Accordingly, the present invention has been made to solve the above-described problems, and hit determination within the time from the end of the control process performed at each predetermined interrupt time until the start of the next control process is performed. A hit value counter is provided to create a numerical value of the data for use, and the value of the jackpot counter when the hit ball wins the start winning opening and the corresponding value at a predetermined timing (for example, at the time of hit determination) or the value of the numerical counter is in a predetermined state It is an object of the present invention to provide a pachinko machine in which the numerical value of the hit determination data cannot be specified from the outside by an illegal post-attachment board or the like by making a big hit at the time of (for example, matching).
[0005]

[0025]
  The RAM 53 is incremented by 1 for each reset interrupt, and a value of a jackpot counter (hereinafter referred to as RND) that repeatedly counts from 0 to N1 (N1 is a positive integer, N1 = 360 in the present embodiment). And a jackpot counter memory 62 that stores the RND when the hit ball has entered the starting winning opening, and one at a time from the end of the control process processed after the reset interrupt to the next reset interrupt. There is provided a hit value counter memory 63 in which the last counted value (hereinafter referred to as ATC) of the hit value counter that is added and repeatedly counted from 0 to N1 is stored at the time of a reset interrupt.
[0026]
  The ROM 54 stores a program memory 59 that stores a control program for controlling the whole, and a first memory that stores a jackpot processing program at a normal probability (when the jackpot probability value is 1 / (N1 + 1)). 60 and a second memory 61 storing a jackpot processing program during the probability fluctuation (in this embodiment, when the jackpot probability value is 4 / (N1 + 1)).
[0027]
  Next, the jackpot determination control process of the control circuit unit 50 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 4 is a main flowchart of a control process when a reset interrupt according to the first embodiment is input. FIG. 5 is a subroutine flowchart of the hit numerical value counter update process according to the first embodiment. FIG. 6 is a subroutine flowchart of the first type start port winning process according to the first embodiment. FIG. 7 is a subroutine flowchart of the jackpot counter update process according to the first embodiment. FIG. 8 is a subroutine flowchart of the hit determination process according to the first embodiment.
  First, when drive power is input to the pachinko machine 1, the CPU 51 determines whether or not the power is turned on (S1). If the power is turned on (S1: YES), the RAM 53 is initialized (S2). Therefore, RND and ATC at this time are zero. Next, after initialization processing of the RAM 53, the subroutine processing of numerical value counter update processing is repeatedly performed until a reset interrupt is input (S3).
[0028]
  Next, the subroutine processing (S3) of the hit value counter update processing will be described with reference to FIG. First, ATC is read from the hit value counter memory 63, and it is determined whether or not ATC is N1 or more (S4). When ATC is N1 or more (S4: YES), 0 is substituted for ATC (S6), and the process returns to determining whether ATC is N1 or more (S4).
  When ATC is less than N1 (S4: NO), the value obtained by adding 1 to ATC is substituted into ATC (S5), and the process returns to determining whether ATC is N1 or more (S4).
  Next, when a reset interrupt occurs, the last counted ATC is stored in the numerical value counter memory 63, and then the process returns to the start of the main flowchart of the reset interrupt process.
[0029]
  Next, the CPU 51 determines whether or not the power is turned on (S1). If the power is not turned on (S1: NO), a first type start port winning process subroutine is performed (S7).
[0030]
  Next, the subroutine processing (S7) of the first type start port winning process will be described with reference to FIG. First, it is determined whether or not a winning detection signal indicating that a pachinko ball has won is entered in the first starting port 35a or the second starting port 43a which is the first type starting port (S8). Then, if the pachinko ball has not won (S8: NO), the process returns to the main routine, and the big hit counter update process subroutine process is performed (S10). If a pachinko ball is won at the first start port 35a or the second start port 43a (S8: YES), the RND at this time is substituted into RND1, and this RND1 is stored in the jackpot counter memory 62. (S9) and return to the main routine. Next, a subroutine process of the big hit counter update process is performed (S10).
[0031]
  Next, the subroutine process (S10) of the big hit counter update process will be described with reference to FIG. First, RND is read from the jackpot counter memory 62, and a value obtained by adding 1 to RND is substituted into RND (S11). Next, it is determined whether or not the RND is equal to or greater than (N1 + 1) (S12). If the RND is equal to or greater than (N1 + 1) (S12: YES), 0 is substituted into the RND and the RND is again assigned to the jackpot counter memory. After being stored in 62 and stored (S13), the process returns to the main routine and a subroutine process of a hit determination process is performed (S14).
  If the RND is less than (N1 + 1), the RND is stored in the jackpot counter memory 62 and stored (S12: NO), and then the process returns to the main routine to execute a subroutine process of the hit determination process (S14).
[0032]
  Next, the subroutine process (S14) of the hit determination process will be described with reference to FIG. First, it is determined whether or not the big hit determination start condition is in effect (S15). If the big hit determination start condition is not satisfied (S15: NO), the process returns to the main routine and performs a subroutine process of a hit numerical value counter update process (S15: NO). S26).
  If the big hit determination start condition is satisfied (S15: YES), RND1 is read from the big hit counter memory 62 (S16). Next, the ATC is read from the hit value counter memory 63 (S17).
  Next, it is determined whether the probability change is in progress (when the jackpot probability value is 4 / (N1 + 1)) (S18), and if it is a normal probability (when the jackpot probability value is 1 / (N1 + 1)) (S18). : NO), it is determined whether RND1 and ATC are equal (S19). If RND1 and ATC are not equal (S19: NO), the process returns to the main routine, and a subroutine process of hit numerical value counter update processing is performed (S26). . If RND1 and ATC are equal (S19: YES), the jackpot process at the normal probability is performed according to the program stored in the first memory 60 (S20), and the process returns to the main routine to update the hit value counter. Processing subroutine processing is performed (S26).
[0033]
  Further, if the probability is changing (when the jackpot probability value is 4 / (N1 + 1)) (S18: YES), it is determined whether RND1 and ATC are equal (S21), and if RND1 and ATC are equal ( (S21: YES) After performing the jackpot process during the probability variation according to the program stored in the second memory 61 (S22), the process returns to the main routine, and the subroutine process of the hit value counter update process is performed (S26).
[0034]
  If RND1 and ATC are not equal (S21: NO), it is determined whether RND1 and (ATC + 1) are equal (S23). If RND1 and (ATC + 1) are equal (S23: YES), the second memory is determined. In accordance with the program stored in 61, the jackpot process during the probability variation is performed (S22), and then the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC + 1) is larger than N1, (ATC + 1−N1) is used instead of (ATC + 1).
[0035]
  If RND1 and (ATC + 1) are not equal (S23: NO), it is determined whether RND1 and (ATC + 2) are equal (S24). If RND1 and (ATC + 2) are equal (S24: YES), After the jackpot process during the probability variation is performed according to the program stored in the memory 61 (S22), the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC + 2) is larger than N1, (ATC + 2-N1) is used instead of (ATC + 2).
[0036]
  If RND1 and (ATC + 2) are not equal (S24: NO), it is determined whether RND1 and (ATC + 3) are equal (S25). If RND1 and (ATC + 3) are equal (S25: YES), After the jackpot process during the probability variation is performed according to the program stored in the memory 61 (S22), the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC + 3) is larger than N1, (ATC + 3-N1) is used instead of (ATC + 3).
[0037]
  If RND1 and (ATC + 3) are not equal (S25: NO), the process returns to the main routine, and a subroutine process of hit numerical value counter update processing is performed (S26).
  However, when (ATC + 3) is larger than N1, (ATC + 3-N1) is used instead of (ATC + 3).
[0038]
  Next, the same hit numerical counter update processing subroutine processing as that of the hit numerical counter update processing subroutine processing (S3) is repeatedly performed until a reset interrupt is input (S26). When a reset interrupt is received, the last counted ATC is stored in the numerical value counter memory 63, and then the process returns to the start of the main flowchart of the reset interrupt process.
[0039]
  As described above in detail, in the pachinko machine 1 according to the first embodiment, the RND is read from the jackpot counter memory 62 every reset interrupt, is incremented by one and is repeatedly counted from 0 to N1, and again the jackpot counter Store in the memory 62. When a pachinko ball wins the first start port 35a or the second start port 43a, the RND at this time is substituted into RND1, and the RND1 is stored in the big hit counter memory 62. Also, the ATC is read from the numerical counter memory 63 between the end of the reset interrupt control process and the next reset interrupt, and is incremented by one from the ATC and counted repeatedly from 0 to N1. Is stored in the hit numerical counter memory 63. Next, at the time of jackpot determination, RND1 is read from the jackpot counter memory 62, the ATC at this time is read from the hit value counter memory 63, and jackpot determination is performed. In the case of the normal probability, if RND1 and ATC are equal, it is determined that the jackpot is made, and the jackpot processing at the normal probability is performed. Further, when the probability is changing, if any one of ATC, (ATC + 1), (ATC + 2), and (ATC + 3) is equal to RND1, it is determined as a big hit, and the big hit processing at the time of changing the probability is performed.
  Therefore, since the time from the end of the reset interrupt control process to the next reset interrupt always changes depending on the contents of each control process, the ATC that is counted at the end of the reset interrupt changes randomly, and the hit value counter memory at the time of jackpot determination It is impossible to specify the ATC value read from 63 at this time from the outside, and it is possible to prevent an illegal act by an illegal retrofitted board or the like. In addition, since a plurality of hit values are created based on the ATC even during probability fluctuations, it is impossible to specify the hit value from the outside, and to prevent fraudulent acts caused by unauthorized retrofit boards etc. Is possible.
  In addition, since it is not necessary to attach a new component to the control board, it is possible to prevent fraudulent acts caused by an illegal retrofitted board or the like at a low cost.
  In addition, by using the ATC at the time of jackpot determination as a hit value, it is necessary to specify the control processing for determining the jackpot from the outside, so it becomes more impossible to specify the ATC at the time of jackpot determination. It is possible to surely prevent fraud by the attached substrate or the like.
  In addition, by setting the maximum value N1 of RND to the maximum value of ATC, the range of values that ATC can take becomes wider, making it more difficult to specify ATC from the outside, and fraudulent acts such as fraudulent retrofitting boards Can be prevented, and it is easy to determine the match between RND1 and ATC at the time of jackpot determination.
[0040]
  Next, a pachinko machine according to the second embodiment will be described in detail. The schematic configuration of the pachinko machine according to the second embodiment is substantially the same as that of the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3).
[0041]
  Next, the jackpot determination control processing of the second embodiment configured as described above will be described based on the flowcharts of FIGS. 5, 7, and 9 to 11. FIG. 9 is a main flowchart of a control process when a reset interrupt according to the second embodiment is input. FIG. 10 is a subroutine flowchart of the first type start port winning process according to the second embodiment. FIG. 11 is a subroutine flowchart of a hit determination process according to the second embodiment.
  First, the jackpot determination control process will be described in detail based on the main flowchart shown in FIG. When driving power is input to the pachinko machine 1, the CPU 51 determines whether or not the power is turned on (S1). If the power is turned on (S1: YES), the RAM 53 is initialized (S2). Therefore, RND and ATC at this time are zero. Next, after initialization processing of the RAM 53, the subroutine processing of numerical value counter update processing is repeatedly performed until a reset interrupt is input (S3).
[0042]
  Next, the corresponding numerical value counter update processing subroutine processing (S3) has the same processing content as the hit numerical value counter update processing subroutine processing (S3) of the first embodiment shown in FIG.
  Therefore, when a reset interrupt is entered, the last counted ATC is stored in the numerical value counter memory 63, and then the process returns to the start of the main flowchart of the reset interrupt process.
[0043]
  Next, the CPU 51 determines whether or not the power is turned on (S1). If the power is not turned on (S1: NO), a first type start port winning process subroutine is performed (S27).
[0044]
  Next, the subroutine processing (S27) of the first type start port winning process will be described with reference to FIG. First, it is determined whether or not a winning detection signal indicating that a pachinko ball has won is contained in the first starting port 35a or the second starting port 43a which is the first type starting port (S28). Then, if the pachinko ball has not won (S28: NO), the process returns to the main routine, and the big hit counter update process subroutine process is performed (S10).
  If a pachinko ball has been won at the first start port 35a or the second start port 43a (S28: YES), the RND at this time is substituted for RND1, and this RND1 is stored in the jackpot counter memory 62. (S29). Next, the ATC at this time is substituted into ATC1, and this ATC1 is stored and stored in the numerical value counter memory 63 (S30), and the process returns to the main routine. Next, a subroutine process of the big hit counter update process is performed (S10).
[0045]
  Next, the subroutine process (S10) of the jackpot counter update process has the same processing contents as the subroutine process (S10) of the hit value counter update process of the first embodiment shown in FIG.
  Therefore, after storing and storing the new RND in the jackpot counter memory 62 (S12: NO or S13), the process returns to the main routine to perform a subroutine process of the hit determination process (S31).
[0046]
  Next, the subroutine process (S31) of the hit determination process will be described with reference to FIG. First, it is determined whether or not the big hit determination start condition is in effect (S32). If the big hit determination start condition is not satisfied (S32: NO), the process returns to the main routine and performs a subroutine process of a hit numerical value counter update process (S32: NO). S26).
  If the big hit determination start condition is satisfied (S32: YES), RND1 is read from the big hit counter memory 62 (S33). Next, ATC1 is read from the hit value counter memory 63 (S34).
  Next, it is determined whether or not the probability change is in effect (when the jackpot probability value is 4 / (N1 + 1)) (S35), and if it is a normal probability (when the jackpot probability value is 1 / (N1 + 1)) (S35). : NO), it is determined whether RND1 and ATC1 are equal (S36). If RND1 and ATC1 are not equal (S36: NO), the process returns to the main routine, and a subroutine process of hit numerical value counter update processing is performed (S26). . Also, if RND1 and ATC1 are equal (S36: YES), after performing jackpot processing at the normal probability according to the program stored in the first memory 60 (S37), the process returns to the main routine and the hit value counter is updated. Processing subroutine processing is performed (S26).
[0047]
  Further, if the probability is changing (when the jackpot probability value is 4 / (N1 + 1)) (S35: YES), it is determined whether RND1 and ATC1 are equal (S38), and if RND1 and ATC1 are equal ( (S38: YES) After performing the jackpot process during the probability variation according to the program stored in the second memory 61 (S39), the process returns to the main routine, and the subroutine process of the hit value counter update process is performed (S26).
[0048]
  If RND1 and ATC1 are not equal (S38: NO), it is determined whether RND1 and (ATC1 + 1) are equal (S40). If RND1 and (ATC1 + 1) are equal (S40: YES), the second memory is determined. In accordance with the program stored in 61, the jackpot process during the probability change is performed (S39), and then the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC1 + 1) is larger than N1, (ATC1 + 1-N1) is used instead of (ATC1 + 1).
[0049]
  If RND1 and (ATC1 + 1) are not equal (S40: NO), it is determined whether RND1 and (ATC1 + 2) are equal (S41). If RND1 and (ATC1 + 2) are equal (S41: YES), After the jackpot process during the probability fluctuation is performed according to the program stored in the memory 61 (S39), the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC1 + 2) is larger than N1, (ATC1 + 2-N1) is used instead of (ATC1 + 2).
[0050]
  If RND1 and (ATC1 + 2) are not equal (S41: NO), it is determined whether RND1 and (ATC1 + 3) are equal (S42). If RND1 and (ATC1 + 3) are equal (S42: YES), the second After the jackpot process during the probability fluctuation is performed according to the program stored in the memory 61 (S39), the process returns to the main routine and the subroutine process of the hit value counter update process is performed (S26).
  However, when (ATC1 + 3) is larger than N1, (ATC1 + 3-N1) is used instead of (ATC1 + 3).
[0051]
  If RND1 is not equal to (ATC1 + 3) (S42: NO), the process returns to the main routine, and a subroutine process of hit value counter update processing is performed (S26).
  However, when (ATC1 + 3) is larger than N1, (ATC1 + 3-N1) is used instead of (ATC1 + 3).
[0052]
  Next, the same hit numerical counter update processing subroutine processing as that of the hit numerical counter update processing subroutine processing (S3) is repeatedly performed until a reset interrupt is input (S26). When a reset interrupt is received, the last counted ATC is stored in the numerical value counter memory 63, and then the process returns to the start of the main flowchart of the reset interrupt process.
[0053]
  As described in detail above, the pachinko machine 1 according to the second embodiment reads the RND from the jackpot counter memory 62 every reset interrupt, adds 1 to the RND, repeatedly counts from 0 to N1, and again hits the jackpot counter memory. 62. When a pachinko ball wins the first start port 35a or the second start port 43a, the RND at this time is substituted into RND1, and the RND1 is stored in the big hit counter memory 62. Also, the ATC is read from the numerical counter memory 63 between the end of the reset interrupt control process and the next reset interrupt, and is incremented by one from the ATC and counted repeatedly from 0 to N1. Is stored in the hit numerical counter memory 63. When a pachinko ball wins the first start port 35a or the second start port 43a, the ATC at this time is substituted into ATC1, and the ATC1 is stored in the hit numerical counter memory 63. Next, at the time of jackpot determination, RND1 is read from the jackpot counter memory 62 and ATC1 is read from the hit value counter memory 63 to determine jackpot. In the case of the normal probability, if RND1 and ATC1 are equal, it is determined that the jackpot is made, and the jackpot processing at the time of the normal probability is performed. Further, when the probability is changing, if any one of ATC1, (ATC1 + 1), (ATC1 + 2), and (ATC1 + 3) is equal to RND1, it is determined as a big hit, and the big hit processing at the time of the probability change is performed.
  Accordingly, since the time from the end of the reset interrupt control process to the next reset interrupt always changes depending on the contents of each control process, the ATC 1 stored when the pachinko ball wins the first start port 35a or the second start port 43a. Also, the value of ATC1 read from the hit value counter memory 63 at the time of jackpot determination cannot be specified from the outside, and it is possible to prevent an illegal act due to an illegal retrofitted board or the like. . In addition, since a plurality of hit values are created based on the ATC 1 even during probability fluctuations, it is impossible to specify the hit value from the outside, and it is possible to prevent fraudulent acts caused by unauthorized retrofit boards and the like. Is possible.
  In addition, since it is not necessary to attach a new component to the control board, it is possible to prevent fraudulent acts caused by an illegal retrofitted board or the like at a low cost.
  Furthermore, by setting the maximum value N1 of RND to the maximum value of ATC1, the range of values that ATC1 can take is widened, making it more difficult to specify ATC1 from the outside, and fraudulent acts such as fraudulent retrofitting boards Can be prevented, and it is easy to determine the match between RND1 and ATC1 at the time of jackpot determination.
[0054]
  The present invention is not limited to the first and second embodiments, and various improvements and modifications can be made without departing from the gist of the present invention. May be.
  (A) In the above embodiment, the maximum value of ATC is N1 (in the case of the above embodiment, N1 = 360). However, a numerical value smaller than N1 (for example, 55) or a numerical value larger than N1 (for example, 777).
  (B) In the above embodiment, the ATC value is the last count value counted from the end of the reset interrupt control process to the next reset interrupt, but the second count value from the end or the third count value from the end is counted. It may be a value or the like.
  (C) In the above embodiment, N1 = 360. However, any numerical value (for example, N1 = 500) may be used.
  (D) In the above embodiment, the ATC 1 uses the ATC count value when the pachinko ball wins the first start port 35a or the second start port 43a. You may use the count value etc. of the last two from the time of winning.
  (E) In the above embodiment, the four winning numerical values at the time of the probability change are sequentially added one by one. However, even if sequentially added by 10 or sequentially added by 20, Numerical values may be added, or four or more hit numerical values may be created.
  (F) In the above-described embodiment, 1 is added to RND and ATC one by one, but -1 or an arbitrary numerical value may be added.
