[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball game machine, and more particularly to a ball game machine that operates properly even if a plurality of symbol start ports are provided.
[0002]
[Prior art]
A ball game machine such as a pachinko machine has a symbol start opening provided on the game board, a symbol display section for stopping after a plurality of symbols are variably displayed, and a big prize opening where the opening and closing plate is opened and closed. It is prepared for. Then, when the game ball wins after passing the symbol start opening, the symbol display unit starts the change of the display symbol, and then when the special symbol corresponding to the big hit state is aligned, the big winning opening is opened and many game balls are opened. Profits can be expected to be paid out.
[0003]
In this type of gaming machine, the jackpot counter is realized by software, and the value of the jackpot counter is updated every predetermined time (P) within a predetermined numerical range. For example, in the case of the processing system as shown in FIG. 12A, a reset signal is given to the CPU every predetermined time (P), and the value of the big hit counter is updated in a part of the periodic execution unit ( ST30). In the case of the processing system as shown in FIG. 12B, the value of the big hit counter is updated in the interrupt processing (periodic execution unit) that occurs every predetermined time (P) (ST30).
[0004]
Then, when the game ball is introduced through the symbol start port, it is determined that the game ball has won (ST31), and a big hit determination process is performed based on the updated value of the big hit counter (ST32). As a result of the determination process, if the value of the jackpot counter (the random number for lottery) matches the jackpot winning value Hit, the special symbols are controlled to be aligned in the stopped state after the variable display in the symbol display section.
[0005]
By the way, in such a pachinko machine, the player advances the game only expecting to win the big hit state, so by providing a plurality of symbol start ports, the player's expectation to the big hit state An attractive gaming machine that can enhance the feeling can be realized.
[0006]
[Problems to be solved by the invention]
However, if a plurality of symbol start openings are provided, it is not uncommon for game balls to enter the plurality of symbol start openings at the same time depending on the setting state of the pachinko machine nails. There is a problem that it becomes a gaming machine with high gambling and lacking interest for the player.
[0007]
That is, for example, when a game ball rushes into two symbol start openings at the same time, in the control method of FIG. 12, since the random numbers for lottery related to the two start openings are the same, the lottery results are also the same. There are only two patterns that either come off or are both big hits, and there is a problem that not only is the gambling property high, but each symbol starting port will have no individuality.
[0009]
The present invention has been made in view of such problems, and it is an object of the present invention to provide a ball game machine that operates properly even when a plurality of symbol start ports are provided.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention is based on a lottery random number value acquired from a random number generation circuit corresponding to a winning when a game ball wins a plurality of determination areas provided on the game board. A ball game machine that performs a lottery process for determining whether or not to generate a state advantageous to a player, wherein the random number generation circuit oscillates a reference clock that is not synchronized with a system clock of a CPU that realizes the lottery process An oscillator; a counter that is updated in response to a change in the reference clock from a first level to a second level; and a latch circuit that acquires a counter value after updating the counter. counter value after after receiving said random number generating circuit a request signal to be supplied independently of the reference clock, corresponding to the reference clock is changed from the second level to the first level The captured in the latch circuit Te, the lottery process, the periodic execution unit repeatedly executed at a period of more than 2 times the update cycle of the counter for each winning of the game balls, based on an output of said latch circuit Executed.
[0011]
In the present invention, since the update interval of the random number generation counter is set to ½ or less of the execution cycle (P) of the periodic execution unit, until one processing of the periodic execution unit is completed, The random number generation counter has at least two values. Therefore, even when two game balls pass through one determination area continuously (see FIG. 11A), an independent lottery operation can be performed. Such an embodiment is particularly effective when the execution period (P) of the periodic execution unit is considerably long.
[0013]
In the present invention, it is preferable to provide a plurality of determination areas and acquire the value of the random number generation counter corresponding to each winning. For example, when two determination areas are provided, the interval for obtaining the value of the random number generation counter is set to P / 2 or more, so that even when a game ball is won simultaneously in two determination areas, The lottery operation can be performed (see FIG. 11B). When K determination areas are provided, the update interval of the random number generation counter may be set to P / K or less, and the lottery random value acquisition interval for each determination area may be set to P / K or more. .
[0014]
FIG. 11B illustrates a case where two symbol start ports (determination areas) are provided and the lottery random number acquisition interval is P / 2.
[0016]
As described above, in the present invention, multiple winning states can occur in winning in a plurality of determination areas (symbol start openings). In the case of such a double winning, the game in the big win state is continuously performed, but it is preferable to hold the winning state and notify the player until the winning game is started.
[0017]
In the present invention, a control program for realizing a gaming operation includes a main processing unit that is continuously executed in an infinite loop and the periodic execution unit that is repeatedly executed every predetermined time during the execution of the main processing. It is preferable to have it. The periodic execution unit is preferably configured to be repeatedly executed by a CPU reset signal generated every predetermined time.
[0018]

If not, the special game ends, but if it passes through the specific area 18b, the special game is continued up to, for example, 16 times, and is controlled in a state advantageous to the player.
[0028]
As shown in FIG. 4, on the back side of the front frame 4, a back mechanism plate 30 that presses the game board 5 from the back side is detachably mounted. The back mechanism plate 30 has an opening 30a formed on the top side thereof. A prize ball tank 33 and a tank rail 34 extending from the prize ball tank 33 are provided.

The game balls paid out from the payout means 35 are paid out to the upper plate 8 from the upper plate discharge port 8a (FIG. 1) via the passage unit 36.
[0029]
The opening 30a of the back mechanism plate 30 is fitted with a back cover 37 mounted on the back side of the game board 5 and a winning ball discharge basket (not shown) for discharging the winning game balls to the winning means 17-19. Are combined. A main control board 39 is disposed inside a case 38 attached to the back cover 37, and a symbol control board 40 is disposed on the front side thereof (FIG. 2). Below the main control board 39, a lamp control board 42 is provided in a case 41a attached to the back cover 37, and a sound control board 43 is provided in a case 41b adjacent to the case 41a.
[0030]
A power supply board 45 and a payout control board 46 are provided inside the case 44 mounted on the back mechanism plate 30 below the cases 41a and 41b. As shown in FIG. 3, a power switch 80 and an initialization switch 85 are arranged on the power board 45. Cases 44 are notched at portions corresponding to these switches 80 and 85, and each of the switches 80 and 85 can be operated simultaneously with a finger.
[0031]
A launch control board 48 is provided inside the case 47 attached to the rear side of the launch means 10. These control boards 39 to 40, 42 to 43, 45 to 46, and 48 are independent boards, and the control boards 39, 40, 42, 43, and 46 excluding the power supply board 45 and the launch control board 48 are connected to the CPU. A computer circuit including a ROM, a RAM, and the like is mounted, and the main control board 39 and the other control boards 40, 42, 43, 46 are electrically connected via a connector with a plurality of signal lines. .
[0032]
The main control board 39 and the other control boards 40, 42, 43, 46 are electrically connected via a connector with a plurality of signal lines, and each control board 40, 42, 43, 46 is connected from the main control board 39. In addition, various control commands for executing a predetermined game operation can be transmitted by one-way communication. By adopting the one-way communication of the control command, it is possible to reliably prevent fraud related to the symbol stop, to remarkably reduce the control load on the main control board 39, and to simplify the transmission control.
[0033]
FIG. 5 is a block diagram showing the configuration of the main control board 39. The main control board 39 of this embodiment includes a CPU circuit 50 having a built-in memory (ROM, RAM), a system clock generating unit 51 for generating an operation clock of the CPU, and a chip select signal for each unit based on an address signal from the CPU. , A random number generation circuit 53 that is updated regardless of the operation clock of the CPU, an output port circuit 54 for outputting data from the CPU, and an input port for the CPU to take in external data The circuit 55, an output drive circuit 56 for outputting a command or the like to each control board, and a switch input circuit 57 for inputting ON / OFF states of switches of each part of the game board. Since this pachinko machine is provided with a random number generation circuit 53 having a configuration different from that of the system clock generation unit 51, there is no fear that the operation of generating the numerical value sequence and the operation of the CPU are synchronized.
[0034]
FIG. 6 is a circuit block diagram illustrating the random number generation circuit 53 in more detail. In this embodiment, the random number generation circuit 53 includes an oscillator 60 using a crystal resonator, a counter 61 that is counted up based on a clock pulse φ from the oscillator 60, and a request signal REQ from the CPU as a clock pulse φ. And a latch 63 that reads the output value of the counter 61 in response to a change in the output value of the D-type flip-flop 62.
[0035]
The counter 61 is a 12-bit counter, for example (numerical range: 0 to 4095), and starts a count-up operation at the rising edge of the clock pulse φ. Note that some processing time τ is required from the start of the count-up operation to the completion of the operation, and during that time (τ), the output of the counter 61 takes an indeterminate value.
[0036]
The D-type flip-flop 62 receives the clock pulse φ via the NOT circuit 64, and reads and outputs the request signal REQ at the falling edge of the clock pulse φ. Note that the request signal REQ from the CPU is normally at the L level, but when the random number value for lottery is required in the processing of the CPU, the request signal REQ becomes the H level for about one cycle of the clock pulse.
[0037]
The D-type flip-flop 62 outputs the request signal REQ at every falling edge of the clock pulse φ. However, since the request signal REQ is normally at the L level, the output value of the D-type flip-flop 62 also remains at the L level. . On the other hand, when the request signal REQ changes to the H level, the output of the D flip-flop 62 changes from the L level to the H level at the falling edge of the clock pulse. Accordingly, in accordance with this, the latch 63 acquires and outputs the value of the counter 61 as the random number for random selection RND.
[0038]
FIG. 7 is a timing chart for explaining the operation of the circuit of FIG. The counter 61 performs a count-up operation at the rising edge of the clock pulse φ from the oscillator 60, and the counter value is stabilized after the delay time τ. FIG. 7 illustrates a state in which the counter value increases as N−1 → N → N + 1 → N + 2.
[0039]
Regardless of such counter operation, the CPU outputs a request signal REQ at an arbitrary timing (t1). In the case of the circuit of FIG. 6, this request signal REQ is read into the D-type flip-flop 62 at the falling edge of the clock pulse φ (t2), and as a result, the output value of the latch 63 becomes the value up to that time. From (M), the value of the counter 61 at that moment changes to (N).
[0040]
Next, the control program for the main control board 39 will be generally described with reference to FIGS. At the start of business, when the power switch 80 is switched on while pressing the initialization switch 85 with the front frame 4 of the pachinko machine 2 opened forward, the DC voltage is changed to the control boards 39-40, 42- Simultaneously with being supplied to 43 and 46, a system reset signal is supplied to each control board.
[0041]
As a result, the game control by the main control board 39 is started, and the control operation is also started in each of the control boards 40, 42, 43, and 46. When the game control is executed and the initialization switch 85 is in an ON state by a pressing operation (S1: yes), first, an initial setting process for initializing each memory and register of the CPU is executed (S2). Next, all the game information stored and retained by the backup power source in the RAM work area and information memory of the integrated circuit is erased (S3), and an initial symbol to be displayed on the first symbol display means 22 is set, Various initial value setting processes such as setting an interrupt cycle for periodically executing an interrupt process during the execution of the game control are executed (S4).
[0042]
On the other hand, when the initialization switch 85 is in the OFF state when the power is turned on (S1: no), a backup data restoration process is performed (S5). The backup data restoration process is a process for restoring the data backed up by the NMI process in the event of a power failure or the like, and this processing is performed when the power is turned on without pressing the initialization switch 85 after the power failure is restored.
[0043]
When the process of step S4 or S5 is completed, random number processing (S6, S7) for outliers repeated in an infinite loop is performed. Note that the random number processing for the off symbol defines a off symbol pattern drawn on the liquid crystal display 16 when the special symbol lottery (S21, S22) is interrupted in the interrupt processing described later.
[0044]
During such an infinite loop process, a timer interrupt occurs every fixed time (for example, 2 ms), and the process shown in FIG. 9A is executed. In the interrupt processing program, the winning counter CT is first updated (S10), and then the switch signal input processing for reading switch signals from various switches including the winning detection sensor is executed (S11). . By this switch signal input process, various game boards 5 including whether or not the game ball has passed through the gate 20, whether or not the game ball has passed through the first symbol start port 17A and the second symbol start port 17B, and the like. Information is grasped.
[0045]
Subsequently, a timer subtraction process is performed, and each numerical value TIME for the timer of the work area initialized in steps S13 and S14 is subtracted (S12). Next, the normal symbol process related to the normal symbol display part of the second symbol display means 23 is executed (S13). For example, if it is determined that the game ball has passed through the gate 20 by the current switch signal input process (S11), the normal symbol display unit 23 displays the value of the winning counter CT updated in step S10. It is determined whether or not a winning symbol is displayed.
[0046]
Then, when the winning state is achieved by this determination processing, the time for variably displaying the normal symbol, the subsequent stop symbol, the opening time of the electric tulip and the opening / closing plate of the first and second start ports 17A, 17B, etc. are determined. Thus, the numerical value TIME1 corresponding to the variable display time or the open time is stored in the work area of the RAM.
[0047]
Then, the process regarding a special symbol is performed (S14). As shown in FIG. 9B, in the special symbol process, first, it is determined whether or not there is a winning at the first starting port 17A based on the result of the switch signal input process (S11). Processing is performed (S21). In the lottery process, the lottery random value RND is acquired from the random number generation circuit 53 (S30), the value is compared with the big hit winning value Hit, and a determination is made, and processing corresponding to the result is performed. For example, in the case of the big hit state, after the change of the special symbol is stopped, the time data TIME2 indicating how long the opening / closing plate of the special winning opening 18 is opened is written in the work area.
[0048]
Subsequently, it is determined based on the result of the switch signal input process (S11) whether or not there has been a prize at the second start port 17B. If a prize has been won, a lottery process is performed (S23). In the lottery process, a random number RND for lottery is obtained again from the random number generation circuit 53 (S30), the value is compared with the big hit winning value Hit to determine whether or not, and processing corresponding to the result is performed (S31). If it is a big hit state, after the change of the special symbol is stopped, the time data TIME2 indicating how long the opening / closing plate of the special winning opening 18 is opened is written in the work area.
[0049]
Thus, in the present embodiment, separate lottery operations are performed in the winning of the first and second start ports 17A, 17B. In addition, since the counter 61 is updated with a reference clock of about 8 MHz, the counter 61 is updated a considerable number of times from the acquisition of the random value in step S21 to the acquisition of the random value in step S22. Therefore, even if winnings to the two start ports 17A, 17B occur at the same time, both of them are out of the way, even if only one big hit winning value Hit is hit, only one side, both hit the state of winning It becomes possible to make.
[0050]
When acquiring the lottery random value RND, the CPU first outputs a request signal REQ for acquiring the lottery random value RND to the random number generation circuit 53. In this embodiment, the request signal REQ is set to the L level after the time (T) of about one cycle of the clock pulse φ has elapsed. However, after the CPU outputs the request signal REQ, The lottery random number value RND is acquired through the input port circuit 55.
[0051]
As described above, in this embodiment, regardless of the timing at which the request signal REQ is output from the CPU, the count value of the counter 61 is output from the latch 63, so that a normal lottery process is always performed. be able to. That is, in a circuit configuration in which the output of the counter 61 is supplied to the input port circuit 55 as it is, the counter value may be read before the output value of the counter 61 is determined, and a normal lottery operation cannot be expected.
[0052]
If there is a control command to be output to the symbol control board 40, the payout control board 46, the sound control board 43, and the lamp control board 42 after the special special symbol processing (S14) as described above, that command should be output. An output process for outputting the control command to the destination control board is executed (S15).
[0053]
Finally, a drive signal output process for outputting a drive signal to the solenoid that opens and closes the open / close claws and the open / close plate of the symbol start ports 17A and 17B and the special winning opening 18 is executed (S16), and the interrupt process is completed. In the drive signal output process (S16), the contents of the work areas that are initially set in steps S13 and S14 and subtracted in the processes in step S12 are referred to. Turns ON to open the opening / closing claw of the first starting port 17A, the opening / closing plate of the second starting port 17B, and the opening / closing plate of the prize winning port 18. The nails and the opening / closing plate are closed. Note that the numerical values of the respective work areas are both 0 before the timer initial values TIME1 and TIME2 are set in steps S13 and S14.
[0054]
Next, the operation content in another embodiment will be described with reference to the flowchart shown in FIG. This game control program is executed due to a reset signal generated every certain time (for example, 2 ms), but the main process including a process for determining whether or not a big hit state is generated, and then the next reset signal is generated. It is roughly divided into residual processing that is performed in an infinite loop.
[0055]
When the reset signal is received, the CPU is initially set (ST1), and it is determined whether or not the start data is a normal value (ST2). The start data is data for recognizing whether or not the present time is power-on, and the specific data True is stored in the memory as start data when the main processing unit ends (ST12), and the value is stored. The determination is made in the process of step ST2.
[0056]
When the power is turned on, since the start data is confirmed as an abnormal value (≠ True), this is confirmed, so that initialization of the work area and initial setting processing are performed as initialization processing of the gaming machine (ST3). , ST4). On the other hand, if the start data is the normal value True, the winning counter CT is first updated (ST5). Hereinafter, the process from the switch input process (ST6) to the drive signal output process (ST11) is executed, and the contents thereof are the same as the contents of S11 to S16 shown in FIG. In addition, before and after these steps ST5 to ST11, a normal electric accessory process, a special electric accessory process, and other error detection processes are also performed. However, the explanation is omitted because it is not directly related to the gist of the present invention. .
[0057]
After completing such normal processing, the specific data (true) is stored in the memory as start data (ST12), and the main processing program is completed. Subsequently, a random number process for an out symbol is performed in an infinite loop until the next reset signal is generated (ST13). The random symbol processing for the off symbol defines the off symbol pattern drawn on the liquid crystal display 16 when the special symbol lottery (ST9) is off in the next main processing program.
[0058]
As mentioned above, although the Example of this invention was described, it has only illustrated the specific example and does not specifically limit this invention. For example, in the case of the above embodiment, the big hit counter is realized by hardware, and the hit counter CT is realized by software, but both may be realized by hardware. Further, it is not necessary that the number of symbol starting ports is two.
[0059]
【The invention's effect】
As described above, according to the present invention, it is possible to realize a ball game machine that operates properly even when a plurality of symbol start ports are provided.
