Description

[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. From the end of the control process performed every predetermined time until the next control process is started, the jackpot value is repeatedly counted from a predetermined initial value to a predetermined value by a counter, and at a predetermined timing. The present invention relates to a pachinko machine that can prevent the jackpot value from being specified from the outside by setting the count value 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 counter for creating a numerical value of the data for use, and the numerical value of the jackpot counter when the hit ball wins the start winning opening and the count value of the counter at a predetermined timing (for example, at the time of hit determination) are in a predetermined state. It is an object of the present invention to provide a pachinko machine in which the 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 (for example, when matching).
[0005]

[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 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, based on the main flowchart shown in FIG. 4, the jackpot determination control process will be described in detail. 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, a subroutine process of numerical value update processing is performed until a reset interrupt is input (S3).
[0028]
  Next, the subroutine process (S3) of the hit value update process will be described with reference to FIG. First, it waits until the control process after the reset interrupt is completed (S4: NO), when the control process is completed (S4: YES), waits for a reset interrupt (S6: NO), and enters a reset interrupt (S6: (YES), the count value of the counter 64 at this time is read, this count value is substituted into the ATC and stored in the hit value counter memory 63, and the process returns to the start of the main flowchart of the reset interrupt process (S8).
[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 (S9).
[0030]
  Next, the subroutine process (S9) of the first type start opening 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 (S10). If the pachinko ball has not won (S10: NO), the process returns to the main routine to perform a subroutine process of the big hit counter update process (S12).
  If a pachinko ball has been won at the first start port 35a or the second start port 43a (S10: YES), the RND at this time is substituted into RND1, and this RND1 is stored in the jackpot counter memory 62. (S11) and return to the main routine. Next, a subroutine process of the big hit counter update process is performed (S12).
[0031]
  Next, the subroutine process (S12) 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 (S13). Next, it is determined whether or not the RND is equal to or greater than (N1 + 1) (S14). If the RND is equal to or greater than (N1 + 1) (S14: 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 (S15), the process returns to the main routine to perform a subroutine process of a hit determination process (S16).
  If the RND is less than (N1 + 1), the RND is stored in the jackpot counter memory 62 and stored (S14: NO), and then the process returns to the main routine to execute a subroutine process of the hit determination process (S16).
[0032]
  Next, the subroutine process (S16) 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 (S17). If the big hit determination start condition is not satisfied (S17: NO), the process returns to the main routine and performs a subroutine process of the hit numerical value update process (S28). ).
  If the big hit determination start condition is satisfied (S17: YES), RND1 is read from the big hit counter memory 62 (S18). Next, the ATC is read from the hit value counter memory 63 (S19).
  Next, it is determined whether the probability change is in progress (when the jackpot probability value is 4 / (N1 + 1)) (S20), and if it is a normal probability (when the jackpot probability value is 1 / (N1 + 1)) (S20). : NO), it is determined whether RND1 and ATC are equal (S21). If RND1 and ATC are not equal (S21: NO), the process returns to the main routine to perform a subroutine process of hit numerical value update processing (S28). On the other hand, if RND1 and ATC are equal (S21: YES), after performing a jackpot process at the normal probability according to the program stored in the first memory 60 (S22), the process returns to the main routine, and the hit value update process Subroutine processing is performed (S28).
[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 (S23), and if RND1 and ATC are equal ( (S23: YES) After performing the jackpot process during the probability variation according to the program stored in the second memory 61 (S24), the process returns to the main routine, and the subroutine process of the hit value update process is performed (S28).
[0034]
  If RND1 and ATC are not equal (S23: NO), it is determined whether RND1 and (ATC + 1) are equal (S25). If RND1 and (ATC + 1) are equal (S25: YES), the second memory is determined. In accordance with the program stored in 61, the jackpot process during the probability variation is performed (S24), and then the process returns to the main routine to perform the subroutine process of the hit value update process (S28).
  However, when (ATC + 1) is larger than N1, (ATC-N1) is used instead of (ATC + 1).
[0035]
  If RND1 and (ATC + 1) are not equal (S25: NO), it is determined whether RND1 and (ATC + 2) are equal (S26). If RND1 and (ATC + 2) are equal (S26: YES), After performing the jackpot process during the probability variation (S24) according to the program stored in the memory 61 (S24), the process returns to the main routine and the subroutine process of the hit value update process is performed (S28).
  However, when (ATC + 2) is larger than N1, (ATC + 1−N1) is used instead of (ATC + 2).
[0036]
  If RND1 and (ATC + 2) are not equal (S26: NO), it is determined whether RND1 and (ATC + 3) are equal (S27). If RND1 and (ATC + 3) are equal (S27: YES), After performing the jackpot process during the probability variation (S24) according to the program stored in the memory 61 (S24), the process returns to the main routine and the subroutine process of the hit value update process is performed (S28).
  However, when (ATC + 3) is larger than N1, (ATC + 2-N1) is used instead of (ATC + 3).
[0037]
  If RND1 is not equal to (ATC + 3) (S27: NO), the process returns to the main routine, and a subroutine process of hit value update processing is performed (S28). However, when (ATC + 3) is larger than N1, (ATC + 2-N1) is used instead of (ATC + 3).
[0038]
  Next, the same hit numerical value update processing subroutine processing as that of the hit numerical value update processing subroutine processing (S3) is repeated until a reset interrupt is input (S28). When a reset interrupt is received, the count value of the counter 64 at this time is read, the count value is substituted into the ATC, the ATC is stored in the hit numerical counter memory 63, and then the main flowchart of the reset interrupt process starts. Return.
[0039]
  As described above in detail, in the pachinko machine 1 according to the first embodiment, the RND is read from the big hit counter memory 62 every reset interrupt of a predetermined period, is added to the RND one by one, and is repeatedly counted from 0 to N1, and again. And stored in 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. Further, after power-on, the counter 64 increments by 1 and continues counting from 0 to N1 repeatedly. At the time of a reset interrupt, the counter 64 reads the count value at this time and assigns this count value to the ATC. The ATC 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, after the power is turned on, the counter 64 increments by 1 and continues counting from 0 to N1, so the count value of the counter 64 at the time of the reset interrupt changes randomly each time, and this count value is The assigned ATC also changes randomly. As a result, it is impossible to specify the ATC value read from the hit value counter memory 63 at the time of jackpot determination 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.
  Further, since the counter 64 is configured by hardware, it is difficult to analyze the count value of the counter 64 from outside by a program process, and thus it becomes impossible to specify the ATC from the outside. It is possible to prevent fraudulent acts caused by an unauthorized retrofitted board or the like. Furthermore, since the counter 64 is configured by hardware, it is not necessary to add a new counting program, and an increase in the necessary memory amount in the control circuit unit 50 can be reduced.
  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.
  Furthermore, by setting the maximum value N1 of RND as the maximum count value of the counter 64, the range of values that the ATC can take is widened, making it more difficult to specify the ATC from the outside, such as an illegal retrofitting board It is possible to prevent fraudulent acts due to the above, and it is easy to determine whether RND1 matches 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, a subroutine process of numerical value update processing is performed until a reset interrupt is input (S3).
[0042]
  Next, the relevant numerical value update processing subroutine processing (S3) has the same processing contents as the hit numerical value update processing subroutine processing (S3) of the first embodiment shown in FIG.
  Therefore, when a reset interrupt is input, the count value of the counter 64 at this time is read, the count value is substituted into the ATC, the ATC is stored in the hit numerical counter memory 63, and the main flowchart of the reset interrupt process starts. Return to.
[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 (S29).
[0044]
  Next, the subroutine processing (S29) 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 (S30). Then, if the pachinko ball has not won (S30: NO), the process returns to the main routine, and the big hit counter update process subroutine process is performed (S12).
  If a pachinko ball is won at the first start port 35a or the second start port 43a (S30: YES), the RND at this time is substituted for RND1, and this RND1 is stored in the jackpot counter memory 62. (S31). Next, the ATC at this time is substituted into ATC1, and this ATC1 is stored and stored in the numerical value counter memory 63 (S32), and the process returns to the main routine. Next, a subroutine process of the big hit counter update process is performed (S12).
[0045]
  Next, the big hit counter update process subroutine process (S12) has the same processing contents as the hit value update process subroutine process (S12) of the first embodiment shown in FIG.
  Therefore, after storing and storing the new RND in the jackpot counter memory 62 (S14: NO or S15), the process returns to the main routine to perform a subroutine process of the hit determination process (S33).
[0046]
  Next, the subroutine process (S33) 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 (S34). If the big hit determination start condition is not satisfied (S34: NO), the process returns to the main routine to perform a subroutine process of the hit numerical value update process (S28). ).
  If the big hit determination start condition is satisfied (S34: YES), RND1 is read from the big hit counter memory 62 (S35). Next, ATC1 is read from the hit value counter memory 63 (S36).
  Next, it is determined whether the probability change is in progress (when the jackpot probability value is 4 / (N1 + 1)) (S37). If the probability is normal (when the jackpot probability value is 1 / (N1 + 1)) (S37). : NO), it is determined whether RND1 and ATC1 are equal (S38). If RND1 and ATC1 are not equal (S38: NO), the process returns to the main routine, and a subroutine process of hit numerical value update processing is performed (S28). On the other hand, if RND1 and ATC1 are equal (S38: YES), after performing a jackpot process at the normal probability according to the program stored in the first memory 60 (S39), the process returns to the main routine, and the hit value update process Subroutine processing is performed (S28).
[0047]
  Further, if the probability is changing (when the jackpot probability value is 4 / (N1 + 1)) (S37: YES), it is determined whether RND1 and ATC1 are equal (S40), and if RND1 and ATC1 are equal ( (S40: YES) After the jackpot process during the probability variation is performed according to the program stored in the second memory 61 (S41), the process returns to the main routine, and the subroutine process of the hit value update process is performed (S28).
[0048]
  If RND1 and ATC1 are not equal (S40: NO), it is determined whether RND1 and (ATC1 + 1) are equal (S42). If RND1 and (ATC1 + 1) are equal (S42: YES), the second memory is determined. In accordance with the program stored in 61, after jackpot processing during probability variation is performed (S41), the process returns to the main routine, and the subroutine processing of hit value update processing is performed (S28).
  However, when (ATC1 + 1) is larger than N1, (ATC1-N1) is used instead of (ATC1 + 1).
[0049]
  If RND1 and (ATC1 + 1) are not equal (S42: NO), it is determined whether RND1 and (ATC1 + 2) are equal (S43). If RND1 and (ATC1 + 2) are equal (S43: YES), After the jackpot process during the probability variation is performed according to the program stored in the memory 61 (S41), the process returns to the main routine and the subroutine process of the hit value update process is performed (S28).
  However, when (ATC1 + 2) is larger than N1, (ATC1 + 1−N1) is used instead of (ATC1 + 2).
[0050]
  If RND1 and (ATC1 + 2) are not equal (S43: NO), it is determined whether RND1 and (ATC1 + 3) are equal (S44). If RND1 and (ATC1 + 3) are equal (S44: YES), After the jackpot process during the probability variation is performed according to the program stored in the memory 61 (S41), the process returns to the main routine and the subroutine process of the hit value update process is performed (S28).
  However, when (ATC1 + 3) is larger than N1, (ATC1 + 2-N1) is used instead of (ATC1 + 3).
[0051]
  If RND1 and (ATC1 + 3) are not equal (S44: NO), the process returns to the main routine, and a subroutine process of hit numerical value update processing is performed (S28).
  However, when (ATC1 + 3) is larger than N1, (ATC1 + 2-N1) is used instead of (ATC1 + 3).
[0052]
  Next, the same hit numerical value update processing subroutine processing as that of the hit numerical value update processing subroutine processing (S3) is repeated until a reset interrupt is input (S28). When a reset interrupt is received, the count value of the counter 64 at this time is read, the count value is substituted into the ATC, the ATC is stored in the hit numerical counter memory 63, and then the main flowchart of the reset interrupt process starts. Return.
[0053]
  As described above in detail, in the pachinko machine 1 according to the second embodiment, the RND is read from the big hit counter memory 62 every reset interrupt of a predetermined period, is added to the RND one by one, and is repeatedly counted from 0 to N1, and again. And stored in 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. Further, after power-on, the counter 64 increments by 1 and continues counting from 0 to N1 repeatedly. At the time of a reset interrupt, the counter 64 reads the count value at this time and assigns this count value to the ATC. The ATC 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.
Therefore, after the power is turned on, the counter 64 increments by 1 and continues counting from 0 to N1, so the count value of the counter 64 at the time of the reset interrupt changes randomly each time, and this count value is The assigned ATC also changes randomly. As a result, ATC1 to which the ATC when the pachinko ball wins the first start port 35a or the second start port 43a is also randomly changed and stored in the hit value counter memory 63. It becomes impossible to specify the numerical value of ATC1 read from the counter memory 63 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 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.
  Further, since the counter 64 is configured by hardware, it is difficult to analyze the count value of the counter 64 from the outside by a program process, and thus it becomes impossible to specify the ATC 1 from the outside. It is possible to prevent fraudulent acts caused by an unauthorized retrofitted substrate or the like. Furthermore, since the counter 64 is configured by hardware, it is not necessary to add a new counting program, and an increase in the necessary memory amount in the control circuit unit 50 can be reduced.
  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 unauthorized retrofit 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 spirit of the present invention. May be.
  (A) In the embodiment, the maximum value of the count value of the counter 64 is set to the maximum value N1 of RND (N1 = 360 in the case of the embodiment), but the maximum value of the count value of the counter 64 is set to N1. A numerical value smaller than (for example, 55) or a numerical value larger than N1 (for example, 777) may be used.

  (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 embodiment, the RND and the counter 64 add 1 each, but may add −1 or any numerical value.
  (G) In the above embodiment, the count value of the counter 64 at the time of the reset interrupt is read and this count value is substituted into the ATC, but the count value at the time of the reset interrupt of the refresh counter built in the CPU 51 is read and this count is A value may be substituted for ATC.
