In the present embodiment, description will be made using a pachinko gaming machine as an example of a gaming 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.

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 random number IC 14 for generating and outputting a random number used for controlling the pachinko gaming machine P. Note that the reset interrupt process shown in the flowchart of FIG. 5 is stored in the ROM 12.
[0012]
FIG. 3 is a block diagram showing an electrical configuration of the random number IC 14. The random number IC 14 includes a random number counter 31, a maximum value register 32, a comparator 33, a random number register 34, an output register 35, a flag register 36, and a flag controller 37.
[0013]
The random number counter 31 is a 10-bit counter that counts up one count every time the M1 signal 11a, which is an operation code fetch signal output from the CPU 11, falls, and the count value is in the range of “0 to 1023”. It can be updated with. The maximum value register 32 is a register for storing the maximum value +1 of the count value updated by the random number counter 31, and any value of “1 to 1024” that is the update range +1 of the random number counter 31. Is written by the CPU 11. The comparator 33 compares the value of the maximum value register 32 with the count value of the random number counter 31, and outputs a clear signal 33 a to the random number counter 31 when both values match, Clear the count value to “0”.
[0014]
Thus, every time the M1 signal 11a is output, the random number counter 31 counts up by one count within a range from “0” to the value −1 stored in the maximum value register 32. In this embodiment, “347” is written to the maximum value register 32 by the CPU 11 so that the random number counter 31 updates the count value in the range of “0 to 346”.
[0015]
The random number register 34 is a register that latches the count value when the random number counter 31 counts a value that is not yet latched in the output register 35. Specifically, the random number register 34 latches the count value of the random number counter 31 when a first latch signal 37b output from a flag controller 37 described later is input. The first latch signal 37 b is output by the flag controller 37 when the flag of the flag register 36 corresponding to the count value of the random number counter 31 is OFF.
[0016]
The output register 35 is a register that latches a value output as a random number value from the random number IC 14, and latches the value of the random number register 34 when the second latch signal 37 c output from the flag controller 37 is input. As will be described later, the second latch signal 37c is output by the flag controller 37 by inputting a CPU reset signal 11b for causing the CPU 11 to execute a reset interrupt process every 2 ms. Therefore, the value of the output register 35, that is, the output random number value of the random number IC 14 is switched every 2 ms corresponding to the CPU reset signal 11b. The CPU reset signal 11b is output at intervals of 2 ms by a gate array (not shown).
[0017]
The flag register 36 is a flag for storing the latched value in the output register 35, and includes a 1024-bit flag corresponding to each value of the random number counter 31. For example, when “5” is latched in the output register 35, the fifth flag of the flag register 36 is turned on. When “100” is latched, the 100th flag of the flag register 36 is turned on. Is done. The flags of the flag register 36 once turned on are turned off all at once by a clear signal 37a output from the flag controller 37.
[0018]
The flag controller 37 is a controller having the following four functions. First, the count value of the random number counter 31 is input, and the on / off state of the flag of the flag register 36 corresponding to the count value is checked. If the flag is off, that is, the input random number counter This is a function for outputting the first latch signal 37 b to the random number register 34 when the count value 31 is not yet latched in the output register 35. As a result, the count value of the random number counter 31 at that time is latched in the random number register 34.
[0019]
The second function is to input a CPU reset signal 11b for causing the CPU 11 to execute a reset interrupt process every 2 ms, and to output a second latch signal 37c to the output register 35. As a result, the value latched in the random number register 34 can be latched in the output register 35 every 2 ms. That is, the value of the output register 35 (the output random number value of the random number IC 14) can be switched every 2 ms.
[0020]
The third function is to input a value latched in the output register 35 by the second latch signal 37c and turn on the flag of the flag register 36 corresponding to the value. Until this function and the first function are combined and the flag of the flag register 36 is turned off, the value already latched in the output register 35 is not latched again in the random number register 34 (and the output register 35). Yes.
[0021]
The fourth function is to count the number of times of the CPU reset signal 11b and to output a clear signal 37a to the flag register 36 when the number of times coincides with the value stored in the maximum value register 32. The flags in the flag register 36 are turned off all at once by the clear signal 37a.
[0022]
As described above, every time the CPU reset signal 11b is input, the value latched in the output register 35 is switched (second function), and the value once latched in the output register 35 is stored in the flag register 36. It is not latched in the output register 35 until the flag is turned off (first to third functions). In addition, since the random number counter 31 updates the count by the M1 signal 11a, as will be described later, the random number counter 31 updates the count more than once in 2 ms which is the output interval of the CPU reset signal 11b. Therefore, the fact that the number of outputs of the second latch signal 37c for switching the value of the output register 35 matches the value stored in the maximum value register 32 means that all random number values have been latched in the output register 35. That is, all random number values are output as random number values of the random number IC 14. Therefore, in this case, in order to repeat the output of the random number value from the random number IC 14, the clear signal 37a is output to the flag register 36, and all the flags in the flag register 36 are turned off.
[0023]
Here, with reference to FIG. 4, the M1 signal 11a that serves as an update trigger for the random number counter 31 will be described. The M1 signal 11a is a signal for fetching the operation code output from the CPU 11, and falls almost simultaneously with the rise of the T1 clock, and rises almost simultaneously after the rise of the T3 clock. The M1 signal 11a 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 11a 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 11a is output twice. In addition, the number of machine cycles constituting one instruction differs depending on the instruction. For this reason, the M1 signal 11a is always output when the instruction is executed by the CPU 11, but the output interval is not constant. That is, the output interval of the M1 signal 11a changes according to the command executed by the CPU 11 (according to the gaming state of the pachinko gaming machine P).
[0024]
Moreover, the M1 signal 11a is a signal that is output about 1000 times or more within 2 ms, which is the output interval of the CPU reset signal 11b. For example, if the operation clock of the CPU 11 is 8 MHz, one clock is 125 ns. Therefore, if the average number of clocks for executing one instruction is calculated to be about 16 clocks, the execution time of one instruction is about 2 μs, so about 1000 instructions are executed in 2 ms. For this reason, the M1 signal 11a is output about 1000 times or more within 2 ms which is the output interval of the CPU reset signal 11b.
[0025]
Therefore, in this embodiment, since the value of the random number counter 31 is updated in the range of “0 to 346” by the M1 signal 11a, the value of the output register 35 that latches the output random number value is switched for 2 ms. In addition, the count value of the random number counter 31 can be reliably updated more than once at unequal intervals.
[0026]
As shown in FIG. 2, the CPU 11, ROM 12, RAM 13, and random number 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.
[0027]
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.
[0028]
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.
[0029]
Next, each process executed by the pachinko gaming machine P configured as described above will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart of reset interrupt processing executed every 2 ms in the control unit C of the pachinko gaming machine P by the CPU reset signal 11b. The game of the pachinko gaming machine P is controlled by this reset interrupt process.
[0030]
In the reset interrupt process, first, it is checked whether or not the process is the process executed first after the power is turned on (S1). If the process is executed first (S1: Yes), after initialization of the RAM 13 (S2), “347” is written in the maximum value register 32 of the random number IC 14 in order to determine the upper limit of the random number update range. (S3). As a result, the random number counter 31 of the random number IC 14 counts up in the range of “0 to 346”, so that the random value output from the random number IC 14 is “0 to 346”.
[0031]
If it is determined that the reset interrupt process is executed after the process of S3 or after the power is turned on in the process of S1 (S1: No), the hit ball has passed the symbol operating gate 4. If this is the case (S4: Yes), the value of the output register 35 that stores the output random number value of the random number IC 14 is read (S5), and whether or not the read value matches one of the winning values (for example, “7”). Judgment is made (S6). If it matches one of the winning values (S6: Yes), it is determined that the jackpot is won and the jackpot processing is executed (S7). In the jackpot processing, a jackpot command is sent from the control unit C to a display device D described later, and the display device D controls the variable display on the LCD display 3 to a jackpot state based on the jackpot command.
[0032]
On the other hand, if the hit ball does not pass the symbol operating gate 4 in the process of S4 (S4: No), the value of the random number IC 14 is not read out, and the output register 35 of the read random number IC 14 in the process of S6. If the value does not match any of the winning values (S6: No), the game is lost, and the process proceeds to S8 without performing the jackpot processing.
[0033]
In the process of S8, after executing each process according to the gaming state of the pachinko gaming machine P, the current reset interrupt process is terminated and the next reset interrupt process is awaited.
[0034]
Here, the operation of the random number IC 14 that outputs a random number value used for the jackpot determination will be described. The random number counter 31 of the random number IC 14 counts up each time the M1 signal 11a output from the CPU 11 falls. When the count value reaches “347” stored in the maximum value register 32, a clear signal is output from the comparator 33. 33a is output to the random number counter 31, and the count value is cleared to "0". Therefore, the random number counter 31 repeats counting up in the range of “0 to 346” by the M1 signal 11a.
[0035]
The count value of the random number counter 31 is input to the flag controller 37. Each time, the flag controller 37 checks the flag of the flag register 36 corresponding to the count value of the random number counter 31. If the flag is turned off, the flag controller 37 outputs the first latch signal 37b, and uses the count value as a random number. The register 34 is latched.
[0036]
The flag controller 37 also outputs a second latch signal 37c by inputting the CPU reset signal 11b that triggers execution of the reset interrupt process (FIG. 5), and is latched by the random number register 34 at that timing. The value stored in the output register 35 is latched. The value latched in the output register 35 is read out as the output random number value of the random number IC 14 by the process of S5 of the reset interrupt process and used for the jackpot determination (S6).
[0037]
The value latched in the output register 35 is also output to the flag controller 37, and the flag controller 37 turns on the flag of the flag register 36 corresponding to the value. By turning on this flag, the latching of the value to the random number register 34 is prohibited from the next time, so that any value from “0 to 346” is output as the output random number value of the random number IC 14. It is possible to prevent the value from being output twice or more.
[0038]
Note that the M1 signal 11a that counts up the random number counter 31 is output about 1000 times or more during 2 ms, which is the output interval of the CPU reset signal 11b. Therefore, after the CPU reset signal 11b is output, the next signal 11b is output. Until the random number counter 31 is updated more than once. Therefore, only the values not latched in the output register 35 can be switched every 2 ms and latched in the output register 35.
[0039]
When the output count of the CPU reset signal 11b coincides with “347” which is the value of the maximum value register 32, all 347 values “0 to 346” are latched once in the output register 35 and used as random values. It will be. Therefore, in this case, the clear signal 37a is output from the flag controller 37 to the flag register 36, all the flags in the flag register 36 are turned off simultaneously, and the output of the random number value is repeated again.
[0040]
As described above, in the pachinko gaming machine P of the present embodiment, the jackpot is determined using the random number value output from the random number IC 14. The random number output from the random number IC 14 has randomness uniformity (when acquired continuously, the same value is not acquired and all values can be acquired with the same probability) It has become. This random value is generated based on the M1 signal 11a whose output interval changes according to the gaming state of the pachinko gaming machine P. Therefore, the “hanging board” cannot grasp the output random number value of the random number IC 14. 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.
[0041]
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.
[0042]
For example, in this embodiment, the random number IC 14 is configured separately from the CPU 11, but the random number IC 14 may be built in the CPU 11. By incorporating the random number IC 14 in the CPU 11, it is possible to prevent illegal acts such as exchanging the random number IC 14 itself, so that the effect of preventing illegal acts can be further improved. Moreover, if the random number IC 14 is built in the CPU and the signal for updating the random number counter 31 of the random number IC 14 (in this embodiment, the M1 signal 11a) is not output to the outside of the CPU 11, the CPU 11 Since the update timing of the random number counter 31 is completely unknown from the outside, it is possible to make it more difficult to grasp the output random number value by the “hanging board” or the like.
[0043]
Further, the flag of the flag register 36 may be changed to a counter. For example, if a 2-bit counter is provided for each value updated by the random number counter 31, the number of latches of each value in the output register 35 can be counted up to three times. Therefore, by adopting such a configuration, it is possible to maintain the uniformity of random numbers within a range in which each random number value rotates three times.
[0044]
Further, the signal for counting up the random number counter 31 is not necessarily limited to the M1 signal 11a, and the random number counter 31 can be updated one or more times at the output interval of the second latch signal 37c. Any speed signal can be used instead of the M1 signal 11a. Therefore, for example, the operation clock φ of the CPU 11 can be used instead of the M1 signal 11a.
[0045]
Further, if such a signal is not only high-speed but also a signal that is constantly output at unequal intervals, the “hanging board” countermeasure can be made more effective as in the case of the M1 signal 11a. For example, a memory request signal output from the CPU 11, an IO request signal, a read signal, a write signal, a refresh signal, a wait signal, a bus request signal, a bus acknowledge signal, any address bus signal, or any A data bus signal or the like can be used in place of the M1 signal 11a. Further, these plural signals may be used in combination.
[0046]
In the present embodiment, the random number register 34 and the output register 35 are configured by separate latch circuits, but may be configured by a single flip-flop. That is, the first latch circuit and the second latch circuit may be configured by a single flip-flop.

Therefore, even if the “hanging board” or the like is connected to the connector, the “hanging board” or the like cannot input the count value update trigger of the counter circuit, and the random number output circuit from the gaming machine random number generation circuit cannot be input. I can't figure out the numbers.

By incorporating the game machine random number generation circuit in the CPU, unauthorized replacement of only the game machine random number generation circuit can be prevented, and the prevention of fraud can be enhanced. In addition, if a random number generation circuit for gaming machines is built in the CPU, and a signal serving as a trigger for updating the count value of the counter circuit is used as an internal signal of the CPU, the signal is not output to the outside of the CPU. The update of the count value of the counter circuit due to the “hanging board” or the like cannot be grasped.

A random number generation circuit 5 for a gaming machine, which is characterized by being performed.

With these signals, it is not necessary to provide a separate circuit for generating the signals, and the circuit cost can be reduced. Each of the above signals, except for the CPU operation clock signal, is constantly output at non-uniform intervals according to the control state of the gaming machine. Can do. It should be noted that some of the above-mentioned signals including the CPU operation clock signal may be used in combination.
[0053]

Therefore, there is an effect that it is impossible to grasp the occurrence timing 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. In addition, n is either a natural number.
