DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the present embodiment, description will be made using a pachinko gaming machine as an example of a ball game machine, in particular, a first type pachinko gaming machine. Note that it is naturally possible to use the present invention for the third kind pachinko gaming machine and other gaming machines.
[0009]
FIG. 1 is a front view of the game board of the pachinko gaming machine P. Around the game board 1, there are provided a plurality of winning holes 2 through which 5 to 15 game balls are paid out by winning a hit ball. In the center of the game board 1, a liquid crystal (LCD) display 3 for displaying symbols as a plurality of types of identification information is provided. The display screen of the LCD display 3 is divided into three in the horizontal direction, and in each of the three divided display areas, symbols are displayed in a variable manner.
[0010]
Below the LCD display 3, a symbol operation gate (first type start port) 4 is provided. When the hit ball passes through the symbol operating gate 4, the above-described variation display on the LCD display 3 is started. Below the symbol operation gate 4, a specific winning opening (large winning opening) 5 is provided. The specific winning opening 5 is a big hit when the display result after the fluctuation of the LCD display 3 coincides with one of the predetermined symbol combinations, so that the hitting ball is easy to win for a predetermined time (for example, 30 It is a winning opening that is opened (until the second elapses or 10 hitting balls are won). A V zone 5a is provided in the specific winning opening 5, and when the hit ball passes through the V zone 5a while the specific winning opening 5 is opened, a continuation right is established and the specific winning opening 5 is closed. Thereafter, the specific winning opening 5 is opened again for a predetermined time (or until a predetermined number of hit balls win the specific winning opening 5). The opening / closing operation of the specific winning opening 5 can be repeated up to 16 times (16 rounds), and the state in which the opening / closing operation can be performed is a state in which a predetermined game value is given (special game state). is there.
[0011]
FIG. 2 is a block diagram showing an electrical configuration of the pachinko gaming machine P. As shown in FIG. The control unit C of the pachinko gaming machine P includes a CPU 11 that is an arithmetic device, a ROM 12 that stores various control programs executed by the CPU 11, and a RAM 13 that is a memory for temporarily storing various data. And a counter IC 14 that counts each time the M1 signal 31 (see FIG. 3) output from the CPU 11 falls. The programs of the flowcharts shown in FIGS. 4 to 7 are stored in the ROM 12 as a part of the control program.
[0012]
The RAM 13 includes a random number counter 13a and a timer counter 13b. The random number counter 13a is a counter for determining occurrence of a jackpot. The value of the random number counter 13a is updated by one count every 2 ms in the range of “0 to 346” by the random number counter updating process (S10) of FIG. The timer counter 13b is a counter for changing the reading time of the value of the random number counter 13a. When a hit ball that is driven into the game area of the game board 1 passes through the symbol operating gate 4, a value that is "+1" is written to the count value of the counter IC 14 to the timer counter 13b. The written value of the timer counter 13b is subtracted by one count by the jackpot determination process (S30) of FIG. 7, and when the count value becomes “0”, the value of the random number counter 13a is read. When the read value of the random number counter 13a matches the winning value (for example, “7”), a big hit is generated. When the jackpot occurs, a jackpot command is sent from the control unit C to the display device D described later. The display device D controls the variable display on the LCD display 3 to the jackpot state based on the jackpot command.
[0013]
The counter IC 14 is a counter that is incremented by 1 every time the M1 signal 31 output from the CPU 11 falls, and is updated in a range of “0 to 255”. The count value of the counter IC 14 is not initialized when the power is turned on, and starts counting up from an indefinite value when the power is turned on. The count value of the counter IC 14 is not cleared even when a reset interrupt occurs every 2 ms, and continues counting.
[0014]
Here, the M1 signal 31 output from the CPU 11 will be described with reference to FIG. The M1 signal 31 is a signal for fetching the opcode, and is a signal that falls almost simultaneously with the rise of the T1 clock and rises almost simultaneously after the rise of the T3 clock. The M1 signal 31 is always output at least once when each instruction is executed by the CPU 11. For example, when the CPU 11 executes an instruction of only the first opcode, the M1 signal 31 is only output once when the instruction is executed, but when executing an instruction having up to the second opcode, When the instruction is executed, the M1 signal 31 is output twice. In addition, the number of machine cycles constituting one instruction differs depending on the instruction. For this reason, the M1 signal 31 is always output when the instruction is executed by the CPU 11, but the output interval of the M1 signal 31 is not constant. That is, the output interval of the M1 signal 31 changes according to the command executed by the CPU 11 (according to the gaming state of the ball game machine 1).
[0015]
In this embodiment, the value of the counter IC 14 is counted up in the range of “0 to 255” by the M1 signal 31, and the read time of the random number counter 13a is changed based on the counted up value. The reading time of the random number counter 13a by the “hanging board” can be made impossible to grasp. Moreover, as described above, the count value of the counter IC 14 is not initialized when the power is turned on, and starts counting up from an indeterminate value when the power is turned on. Also in this respect, the random number counter 13a by the “hanging board” is used. It is possible to make it even more difficult to grasp the read time of. Therefore, it is impossible to grasp the occurrence timing of the jackpot by the “hanging board”, and illegal acts using the “hanging board” can be prevented.
[0016]
The “random number generating means for generating the random number based on the value of the count circuit” includes the “random number generating means for changing the read-out time of the random number based on the value of the count circuit” as in the present embodiment. It is out.
[0017]
As shown in FIG. 2, the CPU 11, ROM 12, RAM 13, and counter IC 14 are connected to each other via a bus line 17. The bus line 17 is also connected to an input / output port 15, which is connected to the display device D and other input / output devices 16. The control unit C sends operation commands to the display device D and other input / output devices 16 via the input / output port 15 and controls these devices. The fluctuation display on the LCD display 3 and the opening / closing operation of the specific winning opening 5 are also controlled based on this operation command.
[0018]
The display device D includes a CPU 21, a program ROM 22, a work RAM 23, a video RAM 24, a character ROM 25, an image controller 26, an input / output port 27, and the LCD display 3. The CPU 21 of the display device D performs display control (variable display) of the LCD display 3 in accordance with an operation command output from the control unit C. The program executed by the CPU 21 is stored in the program ROM 22. Has been. The work RAM 23 is a memory that stores work data used when the CPU 21 executes a program.
[0019]
The video RAM 24 is a memory for storing data to be displayed on the LCD display 3, and the display content of the LCD display 3 is changed by rewriting the content of the video RAM 24. That is, the variable display of the symbols in each display area is performed by rewriting the contents of the video RAM 24. The character ROM 25 is a memory for storing character data such as symbols displayed on the LCD display 3. The image controller 26 adjusts the timings of the CPU 21, the video RAM 24, and the input / output port 27, intervenes in reading and writing data, and displays display data stored in the video RAM 24 at a predetermined timing with reference to the character ROM 25. It is displayed on the LCD display 3.
[0020]
Next, each process executed by the pachinko gaming machine P configured as described above will be described with reference to the flowcharts of FIGS.
[0021]
FIG. 4 is a flowchart of reset interrupt processing executed every 2 ms in the control unit C of the pachinko gaming machine P. In the reset interrupt process, first, it is checked whether or not the process is the first process executed after power-on (S1), and if it is the first process executed (S1: Yes), the RAM 13 Initialization is performed (S2). Note that, as described above, the value of the counter IC 14 is not initialized even in the reset interrupt process executed first after the power is turned on. For this reason, the count of the counter IC 14 is started from an indefinite value that changes every time the power is turned on, and in this respect as well, it is possible to make it impossible to grasp the random value by the “hanging board”.
[0022]
After the execution of the process of S2, or when it is determined in the process of S1 that the reset interrupt process is executed for the second time and after the power is turned on (S1: No), the random number counter update process of FIG. (S10) is executed.
[0023]
FIG. 5 is a flowchart of random number counter update processing. By this process, the value of the random number counter 13a is updated by one count in the range of “0 to 346”. In the random number counter update process, first, it is checked whether or not the value of the random number counter 13a is “346” or more (S11). If the value of the random number counter 13a is less than “346” (S11: No), the value of the random number counter 13a is updated by adding “1” (S12). On the other hand, if the value of the random number counter 13a is “346” or more (S11: Yes), the value is cleared to “0” (S13), and this process is terminated.
[0024]
When the random number counter update process (S10) ends, the process returns to the reset interrupt process of FIG. 4, and then the switch winning process (S20) of FIG. 6 is executed. FIG. 6 is a flowchart of the switch winning process. In the switch winning process, first, it is checked whether or not the hit ball has passed the symbol actuating gate 4 (S21). If it has passed (S21: Yes), the value of the counter IC 14 is read (S22) and read. The value "+1" is written to the timer counter 13b (S23).
[0025]
On the other hand, if the hit ball does not pass through the symbol operating gate 4 in the process of S21 (S21: No), this process is terminated without writing to the timer counter 13b. Note that, as described above, the value obtained by adding “+1” to the value of the counter IC 14 is written in the timer counter 13b, so that any one of “1 to 256” is written and “0” is written. There is no. Therefore, when the hit ball passes the symbol operating gate 4 (S21: Yes), the big hit determination is always performed through the branch of S31: No in the big hit determination process of FIG. 7 (S35).
[0026]
When the switch winning process (S20) ends, the process returns to the reset interrupt process of FIG. 4, and then the jackpot determination process (S30) of FIG. 7 is executed. FIG. 7 is a flowchart of the jackpot determination process. In the jackpot determination process, the value of the random number counter 13a is read at the timing when the value of the timer counter 13b changes from “1” to “0”, and the occurrence of the jackpot is determined. When a jackpot occurs, jackpot processing is performed.
[0027]
In the jackpot determination process, first, it is checked whether or not the value of the timer counter 13b is “0” (S31). If it is “0” (S31: Yes), since the hit ball has not passed the symbol operating gate 4, the jackpot determination is not performed and this process is terminated as it is. On the other hand, if the value of the timer counter 13b is not “0” (S31: No), the hit ball has passed the symbol operating gate 4. Therefore, in this case, “1” is subtracted from the value of the timer counter 13b (S32), and it is determined whether or not the value of the timer counter 13b after the subtraction is “0” (S33).
[0028]
If the value of the timer counter 13b after the subtraction is “0” (S33: Yes), the timing of the jackpot determination has arrived, that is, the read timing of the random number counter 13a has arrived, so the value of the random number counter 13a is read ( Further, it is determined whether or not the read value of the random number counter 13a matches one of the winning values (S35). If the value of the read random number counter 13a matches one of the winning values (S35: Yes), it is determined that the jackpot has been generated, and the jackpot processing is executed (S36).
[0029]
On the other hand, if the value of the timer counter 13b after the subtraction is not “0” in the process of S33 (S33: No), it is not the jackpot determination timing (the reading time of the value of the random number counter 13a). Exit. In the process of S35, when the read value of the random number counter 13a does not match any winning value (S35: No), the process is terminated as it is lost.
[0030]
Since the maximum value written to the timer counter 13b by the process of S23 (FIG. 6) is “256”, the maximum value until the value of the timer counter 13b becomes “0” by the process of S32 (FIG. 7). 512 ms (= 256 × 2 ms) is required. However, in the pachinko gaming machine P of the present embodiment, the shortest time that the hit ball can pass through the symbol operating gate 4 is 600 ms. Therefore, the value of the timer counter 13b written by the process of S23 is surely “0” before the next hit ball passes the symbol operation gate 4. That is, until the value of the timer counter 13b becomes “0”, the next hit ball does not pass through the symbol operation gate 4 to rewrite the value of the timer counter 13b. Therefore, every time the hit ball passes the symbol operating gate 4 (S21: Yes), the big hit determination (S35) can always be performed via the branch of S31: No in FIG.
[0031]
On the other hand, in the pachinko gaming machine P in which the shortest time for the hit ball to pass through the symbol operating gate 4 is 512 ms or less, the maximum value written to the timer counter 13b within the shortest time for the hit ball to pass through the symbol operating gate 4 is The maximum update value of the counter IC 14 may be decreased so as to be “0” (for example, “255” is set to “100”). In addition, when a plurality of storage memories are provided without changing the maximum update value of the counter IC 14 and the next hit ball passes the symbol operation gate 4 before the value of the timer counter 13b becomes “0”. Alternatively, the value of the counter IC 14 at that time may be stored in the storage memory, and the value of the storage memory may be written into the timer counter 13b after the value of the timer counter 13b becomes “0”.
[0032]
After the end of the big hit determination process (S30), the process returns to the reset interrupt process of FIG. 4, executes each process (S3), and ends the current reset interrupt process.
[0033]
As described above, in the pachinko gaming machine P according to the present embodiment, the reading time of the random number counter 13a for determining the occurrence of the jackpot (the jackpot determination timing) is not fixed when the hit ball passes the symbol operation gate 4, and the counter It changes based on the count value of IC14. Specifically, when the hit ball passes through the symbol operating gate 4, the count value of the counter IC 14 is read, and the value obtained by adding “+1” to the count value is changed from “1” to “0”. The value is read out. As described above, the counter IC 14 is counted up every time the M1 signal 31 falls. Since the M1 signal 31 is output at unequal intervals according to the game state of the ball game machine P, the count value of the counter IC 14 counted up based on the M1 signal 31 is grasped by the “hanging board”. It is impossible to do. For this reason, since the “hanging board” cannot grasp the occurrence timing of the jackpot, the passing signal of the symbol operating gate 4 cannot be output to the control unit C of the pachinko gaming machine P in accordance with the occurrence timing of the jackpot. . Therefore, it is possible to prevent an illegal act that unreasonably generates a jackpot by using the “hanging board”.
[0034]
Next, a second embodiment will be described with reference to FIGS. In the first embodiment described above, the read time of the random number counter 13a is changed based on the count value of the counter IC 14. However, in the second embodiment, the value of the random number counter 13a is changed based on the count value of the counter IC 14. Change it. Specifically, the occurrence of the big hit is determined by adding the count value of the counter IC 14 to the random number counter 13a and determining whether or not the value after the addition matches the win value. In the following, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different parts will be described.
[0035]
FIG. 8 is a flowchart of the reset interrupt process of the second embodiment that is executed every 2 ms in the control unit C of the pachinko gaming machine P. In the reset interrupt process, when the reset interrupt process is executed after the second power-on (S1: No), or after the process of S2, the random number counter update process (S10) of FIG. 5 is executed. Thereafter, the jackpot determination process (S40) of FIG. 9 is executed.
[0036]
FIG. 9 is a flowchart of the jackpot determination process of the second embodiment. In the jackpot determination process, when the hit ball passes through the symbol operating gate 4, the count value of the counter IC 14 is added to the value of the random number counter 13a, and the occurrence of the jackpot is determined based on the addition result. When a jackpot occurs, jackpot processing is performed.
[0037]
In the jackpot determination process, first, it is checked whether or not the hit ball has passed the symbol operation gate 4 (S41). If it has passed (S41: Yes), the count value of the counter IC 14 is read (S42), and the random number counter The value of 13a is read (S43), and both the read values are added (S44). It is determined whether or not the value after addition exceeds “346”, which is the upper limit value for updating the random number counter 13a, ie, “347” or more (S45). (S45: Yes), “347” is subtracted from the value after the addition in order to set the value after the addition to “0 to 346” which is a value within the update range of the random number counter 13a (S46). After the subtraction by the process of S46 or when the value after the addition by the process of S44 is less than “347” (S45: No), the value obtained by the process of S44 or S46 is one of the winning values. It is determined whether or not they match (S47). If they match (S47: Yes), it is determined that a jackpot has occurred, and a jackpot process is executed (S36). Note that addition and subtraction in the processing of S44 and S46 are performed by a register in the CPU 11. Therefore, the value of the random number counter 13a is not destroyed by such addition / subtraction.
[0038]
On the other hand, when the value obtained by the process of S44 or S46 does not coincide with any of the winning values (S47: No), the process is terminated as it is a loss. In addition, in the process of S41, if it is not confirmed that the hit ball has passed through the symbol operating gate 4 (S41: No), this process is terminated as it is without determining whether or not a big hit has occurred.
[0039]
After the end of the big hit determination process (S40), the process returns to the reset interrupt process of FIG. 8, executes each process (S3), and ends the current reset interrupt process. The “random number generating means for generating the random number based on the value of the count circuit” includes the “random number generating means for changing the random value based on the value of the count circuit” as in the second embodiment. Yes.
[0040]
As described above, in the pachinko gaming machine P according to the second embodiment, the value of the random number counter 13a is not used for the jackpot determination as it is, and the value of the random number counter 13a is changed based on the count value of the counter IC14. The occurrence of a jackpot is determined based on the changed value. Specifically, when the hit ball passes through the symbol operating gate 4, the value of the random number counter 13 a and the count value of the counter IC 14 are read out, both values are added, and whether or not the value after the addition matches the winning value. The jackpot is judged by what.
[0041]
As described above, since it is impossible to grasp the count value of the counter IC 14 with the “hanging board”, the “hanging board” grasps the value of the random number counter 13 a that is changed based on the count value of the counter IC 14. I can't. Therefore, since the “hanging board” cannot grasp the occurrence timing of the jackpot, the passing signal of the symbol operation gate 4 cannot be output to the control unit C of the pachinko gaming machine P in accordance with the occurrence timing of the jackpot. Therefore, it is possible to prevent an illegal act that unreasonably generates a jackpot by using the “hanging board”.
[0042]
[0043]
The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.
[0044]
For example, in each of the above embodiments, the read time of the random number counter 13a is changed based on the count value of the counter IC 14 (first embodiment), or the count value of the counter IC 14 is added to the value of the random number counter 13a. (2nd Example) The random number value for determining generation | occurrence | production of jackpot was changed (the random value was produced | generated). However, the counter IC updated in the range of “0 to 346” that is the update range of the random number counter 13a may be used directly as the random number value.
[0045]
Further, the signal for counting up the counter IC 14 is not necessarily limited to the M1 signal 31 and can be used instead of the M1 signal 31 as long as it is a signal that is constantly output at unequal intervals. For example, a memory request signal, an IO request signal, a read signal, a write signal, a refresh signal, a wait signal, a bus request signal, a bus acknowledge signal, or any address bus signal output from the CPU 11 The data bus signal or the like can be used in place of the M1 signal 31. Further, these plural signals may be used in combination.

Therefore, there is an effect that it is impossible to grasp the timing of occurrence of the jackpot by the “hanging board” or the like and it is possible to prevent an illegal act using the “hanging board” or the like.
[0052]
According to the bullet ball game machine according to claim 2, in addition to the effect played by the bullet ball game machine according to claim 1, the count circuit that affects the read timing of the random number counter is externally attached to the CPU. Counting can be continued separately from the operation of the CPU. For example, even when the CPU is controlled by a reset interrupt process or the like, the count value of the count circuit is not cleared every time the reset interrupt process is executed, and the count value is maintained and the count is continued. be able to. Therefore, there is an effect that it is possible to make it difficult to grasp the reading timing of the random number counter by the “hanging board” or the like.
[0053]
According to the ball game machine according to claim 3, in addition to the effect achieved by the ball game machine according to claim 1 or 2, the count value of the count circuit is not initialized when the power is turned on. Since the update is started from an indefinite value at the time of turning on, there is an effect that it is impossible to grasp the reading timing of the random number counter by the “hanging board” or the like even when the power is turned on.
[0054]
According to the ball game machine according to claim 4, in addition to the effect produced by the ball game machine according to any one of claims 1 to 3, the count circuit includes an M1 signal and a memory request signal output from the CPU. , IO request signal, read signal, write signal, refresh signal, wait signal, bus request signal, bus acknowledge signal, at least one address bus signal, or at least one data bus signal The count value is updated based on any one of these signals or based on a combination of any one signal and one or more other signals. Since these signals are constantly output from the CPU at non-uniform intervals according to the operating state of the CPU, it is not necessary to separately provide a circuit for generating the signal, and the circuit cost can be reduced. effective.
