Abstract

PROBLEM TO BE SOLVED: To prevent an unfair play by an unfair means such as a body sensing device. SOLUTION: In this game machine, a pulse signal outputted from an oscillator is received by a control device and a count value C of a counter is varied (step S40) from a starting value Cmin to a finishing value Cmax and circulated. The counter is initialized (step S49a) by the starting value Cmax or a count value F, or a variation value Y (arbitrary) in every one cycle (prescribed period) of the counter (step S46) to make prize winning intervals different at least once. Thus, the count value C is started from the starting value Cmin or the count value F, or the variation value Y within one cycle of the counter and the count value C becomes the prize winning value in the next turn from the former prize winning value after a prize winning interval. A player cannot know when and what number does the counter is initialized and the prize winning interval is varied. Consequently, an unfair play can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a gaming machine, and more particularly to a technique for preventing an illegal game.

[0002]

2. Description of the Related Art In a gaming machine such as a pachinko machine or a slot machine, "random" or "out" is determined by a random number value. The value of this random number matches the value of the counter (that is, the count value), and is changed within a predetermined range at intervals (for example, 4 milliseconds). That is, normally, the count value is increased by one, and when the count value reaches the end value, the counter is initialized to the start value and circulated. For example, assuming that the predetermined range is 0 to 299, the starting value is 0
And the end value is 299. In this example, when the count value is 0 to 298, it is incremented by one, and when the count value is 299, it is initialized to 0. Therefore, the counter is continuously updated periodically when the power of the gaming machine is turned on (or at the time of reset).

[0003] The above count value is often used for symbol display on a symbol display provided in a gaming machine. That is, when a game ball wins at the starting port for starting the symbol change, the count value when the winning is detected is read.
Then, according to the read count value (hereinafter referred to as “read value”), the contents of the symbol displayed on the symbol display are controlled. For example, it is assumed that only “7” in the above predetermined range is a hit. If the read value is "7", control is performed such that the content of the symbol displayed on the symbol display is stopped in a "hit" mode (specifically, a hit symbol such as "777"). If the read value is a value other than "7", control is performed such that the content of the symbol displayed on the symbol display is stopped in a "losing" mode according to the value.

Here, the timing at which the game balls enter the starting port in the pachinko machine (hereinafter referred to as "winning timing") is uniform because the game balls behave randomly by a large number of obstacles arranged on the game board. Not. Therefore,
Even if the count value of the counter updated every interval is read at the winning timing, the read value becomes a random value as a result. However, since the counter is updated at intervals, the period from the occurrence of a certain "hit" to the occurrence of the next "hit" becomes constant. The period is equal to the period when the count value goes around the predetermined range,
Hereinafter, it is referred to as a “count period”. When the 300 values are updated every 4 milliseconds in the above example of the predetermined range, the count cycle becomes 1.2 seconds. Therefore, if the game ball wins the starting port 1.2 seconds after the read value once reaches the hit value, the read value at that time also becomes the win value.

Incidentally, there is a so-called "body sensation device" which generates a signal such as vibration or sound at regular intervals. If the player turns on / off the launching device in accordance with the signal generated by the bodily sensation device, the game ball can be fired at regular intervals. In addition, depending on the operation pattern of the member, the player may be able to know the above-mentioned fixed cycle regardless of the sensation. Examples of the operation pattern of this member include a blinking pattern of a lamp provided on a game board surface, a sound effect emitted from a speaker, and an operation pattern of an accessory. Also,
The operation pattern of the member is generally operated at a timing independent of one cycle of the counter. However, if the operation is performed in synchronization with one cycle of the counter due to a design or manufacturing error, the player can know the fixed cycle. If the player turns on / off the firing device according to the operation pattern of this member, the game ball can be fired at regular intervals. However, as described above, since a large number of obstacle nails are provided on the game board surface, the winning timing does not always occur periodically.

[0006]

However, the counter 1
If the game ball is fired in each cycle (1.2 seconds in the above example), the winning timing can be periodically generated. Therefore, it is possible to increase the probability of "winning" at the time of winning the starting opening. Therefore, if a game is played with a bodily sensation device or the like, a "hit" can be almost certainly generated. Such a fraudulent game is a game that is intentionally aimed at a "hit", and is unfair considering ordinary players who aim at a "hit" by chance and should not be allowed. The present invention has been made in view of such a point, and an object of the present invention is to provide a control device for a gaming machine that prevents an illegal game by an illegal means such as a bodily sensation device.

[0007]

According to a first aspect of the present invention, a control device for a game machine according to the first aspect receives a signal output from an oscillator, and changes a count value of a counter from a start value to an end value. The counter is initialized with a start value or an arbitrary value for each predetermined period, and the length of the period from when the counter value of the counter reaches the hit value to the next hit value is changed at least once, and the predetermined game condition is changed. Once established,
The gaming state of the gaming machine is switched based on the count value at that time. According to the control device for a game machine described in claim 1, upon receiving the signal output from the oscillator, the count value of the counter is changed and circulated from the start value to the end value. Then, the counter is initialized with a start value or an arbitrary value for each predetermined period, and the length of a period required from when the count value becomes a hit value to the next hit value (hereinafter, simply referred to as “hit interval”). Are different at least once. In this way, the count value of the counter starts from a start value or an arbitrary value within a predetermined period, and the count value becomes a hit value after a hit interval from the previous hit value. In this case, the player does not know when and what value the counter is initialized and the winning interval changes. For this reason, it is difficult to set “win” (including “big hit”) at the timing of winning or passing in the conventional counting cycle. Therefore, illegal games can be prevented.

Here, the terms described in claim 1 are interpreted as follows. The same applies to the other claims and the detailed description of the invention. (1) The magnitude relationship between the “start value” and the “end value” does not matter. That is, the relationship may be any of the following: start value> end value, start value = end value, start value <end value. The value that can be taken by the count value of the counter is "start value"
And "end value". Further, the count value of the counter is not limited to the range regulated by the start value and the end value, and may be beyond the range. (2) The “arbitrary value” has a constant value or an indefinite value, and usually means any one of a start value ≦ an arbitrary value ≦ an end value. If the range of the count value of the counter is not restricted between the start value and the end value, a value outside the range may be used.

[0009]

According to a second aspect of the present invention, a control device for a gaming machine receives a signal output from an oscillator and changes a count value of a counter from a start value to an end value based on a change value. It changes regularly until it reaches a predetermined or indefinite timing, changes the change value, initializes the counter with a start value or an arbitrary value, and when a predetermined game condition is satisfied, based on the count value at that time To switch the gaming state of the gaming machine. According to the control device for a game machine described in claim 2, upon receiving the signal output from the oscillator, the count value of the counter is changed regularly from the start value to the end value based on the change value. Circulate. Then, while the count value of the counter is being changed, when a predetermined or uncertain timing is reached, the change value is changed, and the counter is initialized with a start value or an arbitrary value. In this case, the length of a period (corresponding to one cycle of the counter, hereinafter referred to as a “transition period”) required for the count value of the counter to change from the start value to the end value is different. Therefore, as a result, the hit interval also changes. In this case, the player does not know when and what value the change value is changed and the counter is initialized. For this reason, it is difficult to obtain a "win" at the timing of winning or passing in the conventional counting cycle. Therefore, illegal games can be prevented.

Here, the term "change value" described in claim 2 includes an increment value for increasing the count value of the counter and a decrement value for decreasing the count value.

[0011]

According to a third aspect of the present invention, there is provided a game machine control device according to the first or second aspect, wherein the count value of the counter is set to a predetermined or indefinite period. Just hold. According to the control device for a gaming machine described in claim 3, when the count value of the counter is changed and the count value is held for a predetermined or indefinite period, the length of the transition period also differs. In this case, since the hit interval changes, it becomes difficult to match the timing of winning or passing. Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[0012]

According to a fourth aspect of the present invention, there is provided a game machine control device according to the first or second aspect, wherein the count value of the counter is set to a predetermined or indefinite period. Only by changing the direction of change. According to the control device for a gaming machine described in claim 4, when the count value of the counter is changed and the count value is changed by changing the change direction only for a predetermined or indefinite period, the transition period is changed. The length also expands and contracts. In this case, since the hit interval changes, it becomes more difficult to match the timing of winning or passing with the timing of "hit". Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[0013]

According to a fifth aspect of the present invention, there is provided a game machine control device according to the first or second aspect of the present invention, wherein the start value and / or the end value of the counter are set by the game device. Change. According to the control device for a game machine described in claim 5, when the count value of the counter is changed and the start value and / or the end value are changed, the length of the transition period also increases. Or shrink. In this case, since the hit interval changes, it becomes more difficult to match the timing of winning or passing with the timing of "hit". Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[0014]

According to a sixth aspect of the present invention, a control device for a gaming machine receives a signal output from an oscillator and receives all signals from a start value to an end value based on a change value. The value of the counter is changed within a predetermined period so as to indicate the value once, and the change value is changed each time the predetermined period elapses. To switch the gaming state of the gaming machine. According to the control device of the gaming machine described in claim 6, the count value of the counter changes based on the change value, and the change mode is set to all possible values from the start value to the end value within a predetermined period. Each is shown once. In other words, the manner of changing the count value is arbitrary, but all values in the range from the start value to the end value can always be taken once within a predetermined period. Since the change value is changed after the elapse of the predetermined period, the change mode is different from the previous predetermined period. In this way, there is an opportunity to “hit” the number of hit values for all possible values, and this opportunity is kept constant. In addition, the fact that the count value of the counter matches the hit value changes depending on the change mode, so that the player does not know when the "hit" occurs.
Therefore, it becomes difficult to match the timing of winning or passing with the timing of "hit". Therefore, illegal games can be prevented.

[0015]

According to a seventh aspect of the present invention, there is provided a game machine control device according to the first aspect, wherein the count value of the counter is set to once in a predetermined period. The count value of the counter is changed so as to match only the hit value. According to the control device for a gaming machine described in claim 7, the count value of the counter is 1 in a predetermined period.
Only match the hit value. Therefore, the probability of winning can be kept constant.

[0016]

According to a eighth aspect of the present invention, there is provided a gaming machine control device according to the first to seventh aspects, wherein the oscillator outputs a signal irregularly. Constitute. According to the control device for a gaming machine described in claim 8, when the oscillator outputs the signal irregularly, the count value of the counter also changes irregularly. Due to the change, the length of the transition period also expands and contracts. In this case, since the hit interval changes, it becomes more difficult to match the winning timing. Further, since the signal output from the oscillator changes irregularly, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[0017]

Is one of the specific areas described later, and acts in the same manner as a normal winning opening to pay out a prize ball (also called a prize ball). The gate only detects the passage of pachinko balls (game balls) by the gate sensor 38, and does not pay out prize balls. The ordinary symbol display 40 displays ordinary symbols (for example, alphanumeric characters and symbols). This ordinary symbol starts to fluctuate when the pachinko ball passes through the gate, and then stops. The special symbol display 42 displays a special symbol (for example, a pattern, an alphanumeric character, a symbol, or the like). This special symbol starts to fluctuate when a pachinko ball is awarded in the first type starting port 18 and then stops.

The first-type starting port 18 is provided with a starting port sensor 34. This starting port sensor 34 is
When a pachinko ball that has won the seed starting port 18 is detected, a winning signal is output. The special winning opening 20 is provided with a lid 20 a, which is opened and closed by a solenoid 32. The special winning opening 20 is provided with a V zone 20b as a special area. If a pachinko ball wins in this V zone 20b at a certain time, the jackpot game state can be continued within a certain limit (for example, 16 times). Except for the game board surface 12, a lower plate 26 for temporarily storing pachinko balls including prize balls, and a speaker 2 for outputting sound effects, music, and the like.

A metal frame sensor 36 is provided. The speaker 28 is provided inside an upper plate 30 that is a receiving tray for award balls, and the touch sensor 24 and the metal frame sensor 36 are provided at predetermined positions. In addition, LEDs, light bulbs, and the like are used for the lamps 16 and are arranged at appropriate positions according to the game content of the pachinko machine 10 and the like.

Next, the main control unit 100 for implementing a pachinko game by the pachinko machine 10 will be described with reference to FIG. The main control unit 100 is provided on the back side of the pachinko machine 10 and has a CPU (processor) 11.
0, ROM 102, RAM 104, oscillator 101, input processing circuit 108, output processing circuit 112, display control circuit 1
14, a communication control circuit 116 and the like.
The oscillator 101 outputs a pulse signal at a substantially constant cycle,
The operation of the CPU 110 is controlled. The CPU 110 is a ROM 1
The pachinko machine 10 is controlled by executing a game control program recorded in the game machine 02. The game control program includes a program for realizing a main process, a jackpot determination process, and the like, which will be described later. This ROM 102 has E
Although a PROM is used, an EEPROM or a flash memory may be used. The RAM 104 stores various data or input / output signals such as the free counter 105 and the like. Although a DRAM is used as the RAM 104, a nonvolatile memory such as an SRAM or a flash memory may be used. The counter 111 is provided in the CPU 110 (for example, a register or a buffer).

The input processing circuit 108 includes the starting port sensor 34
And a winning signal sent from the gate sensor 38, and converted into a data format that can be processed in the main control unit 100,
Data and the like are sent to the CPU 110 and the RAM 104 via the bus 118. The output processing circuit 112 receives the operation data sent from the CPU 110 via the bus 118 and operates various operating devices provided in the pachinko machine 10 such as the lamps 16 and the solenoid 32. The display control circuit 114 receives display data sent from the CPU 110 via the bus 118, and controls the normal symbol display 40 and the special symbol display 42 to display characters, symbols, images, and the like. . The communication control circuit 116 includes the frame control unit 20
0 (or the hall computer 300). Frame control unit 20
Numeral 0 is mainly composed of a CPU similarly to the main control unit 100, and the detailed description is omitted because the configuration is publicly known. In addition, the frame control unit 200 controls firing of a pachinko ball, payout of award balls, and the like necessary for performing a pachinko game, outputting sound effects, music, and the like from the speaker 28, or opening of a door by a metal frame sensor 36. Inspection and the like are performed at a predetermined timing. The hall computer 300 is used to operate a hall (game room), and generally controls devices and equipment such as pachinko machines, slot machines, rental machines, and lighting equipment. Each of the above components is connected to a bus 118.
Are connected to each other.

Next, the counting process performed in the main control unit 100 will be described with reference to FIGS. This counting process includes a case where the count value of the counter is counted up, a case where the count value is counted down,
There are cases where both are mixed. Here, for simplicity, the case of counting up will be described. In the following description, the start value Cmin is the lower limit, and the end value Cmax
Respectively correspond to the upper limit values. The start value Cmin and the end value Cmax can be set to arbitrary numerical values.

In the main processing shown in FIG.
0 shows the overall processing procedure. That is, when the power of the pachinko machine 10 is turned on (or at the time of reset), an initialization process is performed [step S10]. Specific contents of the initialization processing include a state in which the pachinko machine 10 can play a game, such as a start-up processing of various devices provided in the pachinko machine 10 and a processing of clearing the RAM 104 with initial values. I do. In the initialization process, the counter 111 is initialized with a start value Cmin. Then, a game process is performed [Step S12]. In this game process, the pachinko ball is changed when the pachinko ball passes through the gate sensor 38, and the pachinko ball is changed to the first type start port 18
Variance processing of the special symbol display 42 performed when winning
Various processes for realizing a pachinko game are performed, such as a prize ball payout process performed when a pachinko ball is won. One of them is a jackpot determination process, which will be described with reference to FIG. This jackpot determination process,
This is a process for determining whether or not a big hit has occurred.

In FIG. 4, it is determined whether or not a pachinko ball has won the first type starting port 18 (step S20).
If the pachinko ball has won the first-type starting port 18 (YES), the count value C is obtained with reference to the counter 111 (step S22), and the RAM 104
(Or the hit value H stored in the ROM 102)
Is obtained [Step S24]. Then, it is determined whether it is a big hit or not [Step S26]. Specifically, it is determined whether or not the count value C acquired in steps S22 and S24 matches the hit value H. If they match (YES), a jackpot process is performed [step S
28]. In the jackpot process, the jackpot symbol is displayed on the special symbol indicator 42, and the lid 20a of the jackpot 20 is opened for a predetermined period and a predetermined number of times. In this way, the player can obtain many prize balls. That is, when a pachinko ball wins in the first-type starting port 18 (that is, a predetermined game condition is satisfied), the count value C at that time is obtained.
, The game state of the pachinko machine 10 is switched to whether or not to execute the jackpot processing. On the other hand, the first type starting port 18
When the pachinko ball has not been won (NO in step S20) or when there is no jackpot (N in step S26).
In O), the jackpot process ends without doing anything thereafter.

Returning to FIG. 3, after the game processing of step S12 is completed, free counter processing is performed until an interval Δt (for example, 4 milliseconds) elapses from the start of execution of step S12 (step S16) [step S1]
4]. In this free counter process, a process of counting up the count value F of the free counter 105 stored in the RAM 104 is performed. FIG. 5 shows specific processing contents of the free counter processing. Therefore, when the interval Δt has elapsed (YES in step S16), the count value F is determined. The relationship between the start value Fmin and the start value Cmin is arbitrary, and the start value Fmin> the start value Cmin, the start value Fmin = the start value Cmin, and the start value Fmi.
Any relationship among n <start value Cmin may be used. The same applies to the relationship between the end value Fmax and the end value Cmax.

In FIG. 5, first, the free counter 105
Is incremented by one (step S30). Specifically, the calculation of F = F + 1 is performed. As a result of this calculation, it is determined whether or not the count value F has reached the end value Fmax (step S34). That is, F ≧ Fma
It is determined by whether or not x is satisfied. If the count value F has reached the end value Fmax (YES), the free counter 105 is initialized with the start value Fmin [Step S3]
6]. Specifically, substitution of F = Fmin is performed. The value to be initialized is not limited to the start value Fmin, but may be any other value. On the other hand, if the count value F has not reached the end value Fmax (NO), the free counter process is terminated without doing anything.

Instead of (or in addition to) step S30, a change value X is obtained by referring to the data table TB2 based on the count value F of the free counter 105, and the change value X is used as the count value F. The process of adding may be arbitrarily performed [Step S32]. That is, F
= F + X. In this way, the count value F changes variously depending on the change value X. Data table TB2
Are stored in the RAM 104 (or the ROM 102 or the like), and a plurality of change values X with respect to the count value F to be referred to are set. In step S36, the end value Fmax is subtracted from the count value F, and the free counter 105
May be initialized. Specifically, the calculation of F = F−Fmax is performed.

Returning to FIG. 3, when the free counter process is completed, a main counter process is performed (step S18).
In the main counter process, a process of counting up a count value C of a counter 111 provided in the CPU 110 is performed. FIG. 6 shows specific processing contents. FIG.
First, the count value C of the counter 111 is counted up by a change value N (N is a natural number) [Step S
40]. Specifically, the calculation of C = C + N is performed. As a result of this calculation, it is determined whether or not the count value C has reached the end value Cmax (step S42). Specifically, C ≧ Cma
It is determined by whether or not x is satisfied. If the count value C has reached the end value Cmax (YES), the end value Cmax is subtracted from the count value C to initialize the counter 111 [step S44]. Specifically, C = C-Cmax
Is calculated. Then, it is determined whether one cycle (transition period) has passed based on the calculation result of step S44 [step S46]. Specifically, the determination is made based on whether the count value C matches the start value Cmin. If one cycle has passed (YES), the change value N is changed [Step S48], and then the main counter process ends.
Specifically, the count value F of the free counter 105 is set to the count value C of the counter 111. That is, C
= F is substituted. On the other hand, when the count value C has not reached the end value Cmax in step S42 (NO).
Also, one cycle has not passed in step S46 (N
O) At this time, the main counter process is terminated without doing anything.

In step S44, the counter 11
1 may be initialized with the starting value Cmin. Specifically, C =
Substitute Cmin. In this case, be sure to perform step S48.
Is executed, the count value C always changes. The value to be initialized is not limited to the start value Cmin, and may be any other value. Step S48 is executed when one cycle has elapsed (step S46), but step S48 may be executed depending on whether or not a predetermined event has occurred. This “predetermined event” includes all events that occur in the gaming machine, not limited to fluctuations in symbols, winning or passing of game balls to a specific area, out balls, or launch of game balls. In addition, the specific condition may be changed in a timely manner according to a game state or the like. In this case, the change value N changes each time a predetermined event occurs, so that the hit interval also changes.

Further, instead of (or in addition to) the processing content of step S48, the following processing (a1) to (a1)
(A3) may be performed. By these processes,
Since the hit interval changes, illegal games can be prevented. (A1) The change value Y is acquired by referring to the data table TB4 based on the count value C of the counter 111, and the change value Y is set as the count value F of the free counter 105. That is, substitution of F = Y is performed. In this case, the count value C changes variously depending on the change value Y. The data table TB4 is stored in the RAM 104 (or the ROM 102).
Etc.), and a plurality of change values Y with respect to the reference count value C are set. (A2) The start value Cmin and / or the end value Cmax are changed based on the count value F (or the change value Y) [Step S49a]. Specifically, Cmin = Cmin
+ N, Cmin = Cmin-N, Cmax = Cmax + N, Cma
At least one of x = Cmax-N is executed. This changes the range in which the count value C of the counter 111 changes, so that the length of one cycle (transition period) changes and the hit interval also changes. (A3) The hit value H is changed [Step S49b].
Specifically, the number of hit values is changed, or the hit value itself is changed. In this way, when the count value C of the counter 111 changes within a certain range, the timing at which the count value C matches the hit value H changes. Therefore, as a result, the hit interval changes.

Returning to FIG. 3, when the main counter process is completed, the process returns to step S12. Steps S12 to S18 are repeatedly executed until the power of the pachinko machine 10 is turned off (or reset). As a result, the count value C of the counter 111 changes as shown in FIGS. Note that, in the examples shown in FIGS. 7 and 8, they are continuous at time t28. The count value C in the example shown in FIGS. 7 and 8 changes in 17 steps including the start value Cmin and the end value Cmax. A period during which the counter 111 can continuously take one count value C is an interval Δt. The hit value H is set seven steps above the start value Cmin. A period Tc in which the counter 111 indicates once all the possible values from the start value to the end value corresponds to one cycle (transition period), and has a length of 17 × Δt in this example. This one cycle corresponds to time t10 to time t in FIG.
16 (N = 1), time t16 to time t22 (N = 2),
Time t22 to time t28 (N = 3), time t28 to time t34 (N = 5), time t34 to time t4 in FIG.
0 (N = 7) and time t40 to time t46 (N = 11), respectively. Note that the value of N shown in parentheses is the value in FIG.
Is added to the counter 111 in step S40 shown in FIG.

Here, in the examples shown in FIGS. 7 and 8, there is only one hit value H, but it is also possible to set a plurality of hit values H at any time and with any value. In this case, the probability of "hit" (hit probability) increases. The number of hit values H may be changed at a predetermined or indefinite timing, or may be changed according to a game state or the like. Further, the change value N is not limited to the case where N = 1, 2, 3, 5, 7, and 11, and the counter 111 sets the change value N from the start value Cmin to the end value C
Regarding the number of all possible values up to max, any value may be used except for the number and its divisor. Therefore, in the case of the examples shown in FIGS.
Since the number of all possible values from n to the end value Cmax is 17, any of N = 1 to 16 can be taken. These are the same in other embodiments.

In the process of changing the count value C of the counter 111 in this way, the "miss" which does not coincide with the hit value H.
Are periods Td2 (time t10 to time t12), period Td4 (time t14 to time t18), and period Td6 (time t20 to time t24) in FIG. 7, and period Td8 (time t26 to time t30) in FIG. ), Period Td
10 (time t32 to time t36) and period Td12 (time t38 to time t42). The lengths of these periods correspond to the hit intervals, respectively, and are different as is apparent from FIGS. That is, if the change value N is different from the change value N in the previous period Tc, the hit interval also changes. Therefore, by changing the count value F of the free counter 105 and substituting it into the change value N, the hit interval changes, and the hit interval differs from the previous hit interval. Even if the timing of winning or passing is determined in the conventional counting cycle, it is difficult to make the count value C coincide with the hit value H to make it "hit". Also, the count value F
The player does not know what value is, and when and how much the hit interval changes. Therefore, illegal games can be prevented.

According to the first embodiment, in response to the pulse signal output from the oscillator 101, the count value C of the counter 111 is changed from the start value Cmin to the end value Cmax. And circulate (Fig. 3
Step S18). Then, the counter 111 is set to a start value Cmin every one cycle (predetermined period) of the counter 111.
Alternatively, initialization is performed with the count value F and the change value Y (arbitrary value) (step S49a shown in FIG. 6), and the hit interval is changed at least once. In this case, the counter 111
In one cycle, the count value C starts from the start value Cmin or the count value F and the change value Y, and the count value C
Becomes the next hit value H after a hit interval from the previous hit value H. In this case, the player does not know when and what value the counter 111 is initialized and the winning interval changes. For this reason, it is difficult to obtain a "win" at the timing of winning or passing in the conventional counting cycle. Therefore, illegal games can be prevented.

According to a second aspect of the present invention, the counter 11
While changing the count value C, the change value N is changed every cycle (when a predetermined timing is reached) (step S48 shown in FIG. 6), and the counter 1
11 is initialized with the start value Cmin or the count value F and the change value Y. In this case, the length of the transition period corresponding to one cycle of the counter 111 differs, and as a result, the hit interval also changes. In this case, the player does not know when and what value the change value N is changed and the counter 111 is initialized. For this reason, it is difficult to obtain a "win" at the timing of winning or passing in the conventional counting cycle. Therefore, illegal games can be prevented. Note that the change value N may be changed when an indefinite timing is reached. The indefinite timing includes when a predetermined event occurs.

Further, according to claim 5, the counter 1
While changing the count value C of 11, the start value Cmi
Changing n and / or end value Cmax will also increase or decrease the length of the transition period. In this case, since the hit interval changes, it becomes more difficult to match the timing of winning or passing with the timing of "hit". Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

According to the sixth aspect, the counter 1
11 is changed based on the change value N (FIG. 6).
Step S40 shown in FIG.
All possible values from the start value Cmin to the end value Cmax in one cycle are shown once (see FIGS. 7 and 8). That is, the manner of changing the count value C is arbitrary, but all values in the range from the start value Cmin to the end value Cmax can always be taken once in one cycle.
Since the change value N is changed after one cycle (step S48 shown in FIG. 6), the change mode is different from the previous one cycle. In this way, there is an opportunity to “hit” the number of hit values for all possible values, and this opportunity is kept constant. In other words, in the examples of FIGS. 7 and 8, there is always an opportunity to hit once per cycle. At this time, the fact that the count value C of the counter 111 matches the hit value H changes depending on the change mode, and therefore, the player does not know when the "hit" occurs. Therefore, it becomes difficult to match the timing of winning or passing with the timing of "hit". Therefore, illegal games can be prevented.

Then, according to claim 7, the count value C of the counter 111 coincides with the hit value only once in one cycle (see FIGS. 7 and 8). Therefore, the probability of winning can be kept constant.

[Second Embodiment] Next, a second embodiment in which the change is temporarily stopped in the process of changing the counter from the start value to the end value will be described with reference to FIGS. It will be described with reference to FIG. Here, FIG. 9 is a flowchart showing the second main counter process. FIG. 11A is a time chart showing a temporal change in the count value when the second main counter process is performed. Note that the configurations of the pachinko machine 10 and the main control unit 100 are the same as those in the first embodiment, and a description thereof will be omitted.
Therefore, points different from the first embodiment will be described. Note that the same elements as those shown in FIGS. 6 to 8 are denoted by the same reference numerals and description thereof will be omitted.

In the main counter processing shown in FIG.
The difference from the main counter process shown in FIG. 6 is that whether to count up the counter 111 is determined based on whether or not a specific condition is satisfied [step S50]. Here, the “specific conditions” are set in advance according to the type of pachinko machine, date and time, and the like. The specific condition may be when the above-described predetermined event occurs. In addition, the specific condition may be changed in a timely manner according to a game state or the like. Examples of the specific condition being satisfied include a case where a pachinko ball has won or passed a specific region (such as the first type starting port 18), a case where a big hit has occurred, and the like. Therefore, the period in which the specific condition is satisfied may be a predetermined (constant) period or an indefinite period.

In a normal state (N in step S50)
O), the counter 111 counts up. However, if the specific condition is satisfied (YE in step S50)
S), the counter 111 does not count up. Therefore, while the specific condition is satisfied, the counter 111
Will not change. As a result, the count value C of the counter 111 changes as shown in FIG. That is, when the count value C changes regularly as in the first embodiment, the count value C changes like a change pattern P0. However, in the example shown in FIG. 11A, as a result of the specific condition being satisfied from time t50 to time t52, the state changes as in the change pattern P2. That is, the count value C does not change during the period from the time t50 to the time t52, and increases in a period other than the period. Thereafter, at time t54, the count value C matches the hit value H. Note that the actual count value C changes stepwise at intervals of Δt as shown in a circle shown in the figure (see FIGS. 7 and 8). In FIG. 11A,
In order to make the entire change pattern easy to understand, the change in the count value C is indicated by oblique lines. This is the same in FIG. 11B described later.

According to the second embodiment, when the count value C of the counter 111 is changed while the count value C of the counter 111 is being changed, the count value C is changed while a specific condition is satisfied (predetermined or indefinite). For a period). As a result, the length of the transition period differs, and the hit interval changes. This makes it difficult to match the timing of winning or passing. Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[Third Embodiment] Next, FIGS. 10 and 11 show a third embodiment in which the direction of change is temporarily changed while the counter changes from a start value to an end value.
This will be described with reference to FIG. Here, FIG. 10 is a flowchart showing the third main counter process. FIG.
FIG. 1 (B) is a time chart showing a change over time of the count value when the third main counter process is executed. Note that the configurations of the pachinko machine 10 and the main control unit 100 are the same as those in the first embodiment, and a description thereof will be omitted. Therefore, points different from the first embodiment will be described. Note that the same elements as those shown in FIGS. 6 to 9 are denoted by the same reference numerals and description thereof will be omitted.

The main counter processing shown in FIG. 10 differs from the main counter processing shown in FIG. 6 in that the sign of the change value N is inverted depending on whether or not a specific condition is satisfied [steps S50 and S52]. . Here, the “specific conditions” are the same as in the second embodiment,
In the third embodiment, a predetermined or indefinite period is maintained, whereas in the third embodiment, it is instantaneous. Therefore, when playing a pachinko game, the specific condition is satisfied for each predetermined or indefinite period.

In a normal state (N in step S50)
O), the sign of the change value N remains as it is and is not inverted.
However, if the specific condition is satisfied (YE in step S50)
S), the sign of the change value N is inverted. That is, N = −N
Is assigned. Therefore, every time a specific condition is satisfied,
The count value C of the counter 111 starts to increase or starts to decrease. As a result, the count value C of the counter 111 changes as shown in FIG. That is, in the example shown in FIG.
As a result of the specific condition being satisfied at 62, the state changes like a change pattern P4. That is, the count value C is equal to the time t6.
It decreases from 0 to time t62 and increases in other periods. Thereafter, at time t64, the count value C matches the hit value H.

According to the third embodiment, while changing the count value C of the counter 111, the direction of change (increase or decrease) of the count value C every time a specific condition is satisfied. ) Has changed. Therefore, the direction of change changes and changes for a predetermined or indefinite period, and the length of the transition period also expands and contracts. In this case, the winning interval also changes, so that it becomes more difficult to match the timing of winning or passing with the timing of “hit”. Also, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[Fourth Embodiment] Next, a fourth embodiment for realizing the present invention using a counter block will be described with reference to FIG.
This will be described with reference to FIGS. Here, FIG. 12 is a block diagram showing the configuration of the second control unit. FIG. 13 shows the configuration of the counter block. FIG. 14 shows the configuration of the oscillator. Specifically, FIG. 14A shows a case where a crystal oscillator is used, FIG. 14B shows a case where a resistor or a capacitor is used, and FIG. 14C shows a case where an inverter is used. Are respectively shown. FIG. 15 is a flowchart showing the processing performed in the counter block. Note that the configurations of the pachinko machine 10 and the main control unit 100 are the same as those in the first embodiment, and a description thereof will be omitted. Therefore, points different from the first embodiment will be described. In addition,
The same elements as those shown in FIGS. 1 to 11 are denoted by the same reference numerals and description thereof will be omitted.

The main control unit 100 shown in FIG.
Is a main control unit 100 shown in FIG. The difference from FIG. 2 is that the counter 111 is
This is the point that has been realized. This counter block 106
13 is shown in FIG. In FIG. 13, the counter block 106 includes a counter 107c, a comparator 107d, and a setting register 107e. Oscillator 1
A configuration example of 07a will be described later. Counter 107
c receives the pulse signal output from the oscillator 107a and counts up the count value C. Further, the counter 107c receives the clear signal output from the setting register 107e, and initializes it with the start value Cmin. further,
The counter 107c receives the read signal output from the CPU 110 via the bus 118, and sends the count value C at that time to the CPU 110 via the bus 118. The setting register 107e stores the CPU 110 (or the frame control unit 20).
0 or a hall computer 300 etc.) through the bus 118 to temporarily record (store) the set values. This set value specifically corresponds to the end value Cmax. The comparator 107d outputs a clear signal when the count value C of the counter 107c matches the set value of the setting register 107e, and does not output anything when they do not match.

FIG. 14 shows an example in which the oscillator 107a is constituted by a self-excited oscillation circuit. Here, FIG. 14A shows a circuit configuration of an oscillator using a crystal oscillator, and FIG.
14B illustrates a circuit configuration of an oscillator using a resistor and a capacitor, and FIG. 14C illustrates a circuit configuration of an oscillator in which inverters are connected in multiple stages.

The oscillator shown in FIG. 14A includes inverters (NOT circuits) Q10 and Q12, a resistor R10, a crystal resonator XL, and capacitors C10 and C12. A resistor R10 and a crystal resonator XL are connected in parallel to both ends of the inverter Q10, and are further connected to the ground via capacitors C10 and C12, respectively. An inverter Q12 is connected in series to the inverter Q10, and a pulse signal PL is periodically output from the output side of the inverter Q12. In this oscillator, the cycle of the pulse signal PL depends on the oscillation frequency of the crystal resonator XL. Note that, instead of the crystal resonator XL, another type of resonator such as a ceramic resonator may be used.

The oscillator shown in FIG. 14B includes inverters Q14 and Q16, a resistor R12, and a capacitor C14. A resistor R12 is connected in parallel to both ends of the inverter Q14. Also, the capacitor C14, the inverter Q14, and the inverter Q16 are connected in series in this order from the ground side. One side of the capacitor C14 not connected to the inverter Q14 is connected to the ground, and the pulse signal PL is periodically output from the output side of the inverter Q16. Note that a value obtained by multiplying the capacitance value of the capacitor C14 by the resistance value of the resistor R12 (= C14 × R12)
Is a time constant, which is substantially equal to the period of the output pulse signal PL.

The oscillator shown in FIG. 14C includes four inverters Q18, Q20, Q22, and Q24. These inverters Q18, Q20, Q2
2 and Q24 are connected in series. Further, the output side of the inverter Q22 is connected to the input side of the inverter Q18 to form a feedback loop. And the inverter Q2
4 outputs a pulse signal PL periodically.
In this example, the inverter is connected in four stages.
It is also possible to connect the inverters in multiple stages (tens to hundreds of stages). Each inverter delays by a very short time until the input pulse signal is output, and the delay time Δd is proportional to the number of inverters connected in multiple stages. Therefore, a value obtained by multiplying the number of inverter stages n by the delay time Δd (= n × Δd) is substantially equal to the cycle of the output pulse signal PL.

The counter block 106 having the above configuration
Are processed in the procedure of the block count process shown in FIG. This block count process is executed instead of the free counter process shown in FIG. In FIG. 15, first, it is determined whether or not a pulse signal output from the oscillator 107a has been received (step S60). If a pulse signal has not been received (NO), nothing is performed and step S
Go to 70. In this case, the count value C of the counter 107c remains held. On the other hand, if a pulse signal has been received (YES in step S60), it is determined whether a stop signal has been received from CPU 110 [step S6.
2]. If a stop signal has been received (YES), the process proceeds to step S70. Also in this case, the count value C of the counter 107c remains held. On the other hand, when the stop signal has not been received (NO in step S62), the count value C is counted up (step S64). Specifically, an operation of C = C + 1 is performed. And the count value C
Is determined to have reached the end value Cmax [Step S
66]. Specifically, it is determined whether or not C ≧ Cmax is satisfied. If the count value C has reached the end value Cmax (YES), the end value Cmax is subtracted from the count value C to initialize the counter 107c [step S6].
8]. Specifically, the calculation of C = C-Cmax is performed. On the other hand, if the count value C has not reached the end value Cmax (NO in step S66), the next step S
Go to 70.

Next, it is determined whether a clear signal has been received from the comparator 107d (step S70). If the clear signal has not been received, the process proceeds to step S74. Also in this case, the count value C of the counter 107c remains held. On the other hand, when a clear signal is received, (YE
S), similarly to step S68, the counter 107c is initialized with the start value Cmin [step S72]. This start value Cmin is obtained in advance from the CPU 110 directly by the counter 107c.
Set to. It should be noted that the start value Cmi
You may change the value of n. Then, it is determined whether or not a read signal has been received from the CPU 110 (step S74).
If the read signal has not been received (NO), the process returns to step S60. On the other hand, when the read signal is received (YES), the count value C is sent to the CPU 110 via the bus 118 [Step S76], and then Step S60 is performed.
Return to Depending on the contents of this processing, usually, step S64
The count value C is counted up by the CPU 1
10 can output a read signal to the counter 107c to obtain the count value C. When the count-up is stopped and the count value C is held, the counter 1
What is necessary is just to output a stop signal to 07c. Further, the start value Cmin can be set in the counter 107c and the end value Cmax can be set in the setting register 107e, and can be changed. Therefore, the start value Cmin and / or the end value Cma
x can be changed. In step S68, the end value Cmax is subtracted from the count value C.
In 2, the start value Cmin is substituted, but it may be performed in the reverse manner. Alternatively, either one of the subtraction or the substitution may be performed in both steps.

According to the fourth embodiment, when the oscillator 107a outputs a pulse signal irregularly, the count value C of the counter 107c also changes irregularly. Since the length of the transition period expands and contracts due to the change, and the hit interval changes, it becomes more difficult to match the winning timing. Further, since the pulse signal output from the oscillator 107a changes irregularly, the player cannot know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented. Here, when the oscillator 107a is configured by the self-excited oscillation circuit shown in FIG. 14, the interval between the pulse signals PL is not so high, and becomes non-uniform. This tendency becomes more remarkable as an oscillator with lower accuracy is used. Also, the period (corresponding to one cycle, a transition period) required for the counter 107c to indicate the value in the range from the start value Cmin to the end value Cmax once each is also non-uniform. Therefore, FIG.
The count value C obtained by executing steps S64 and S72 shown in FIG. Furthermore, since the hit intervals are also non-uniform, even if the pachinko ball is fired in accordance with one cycle of the counter as in the related art, the game state is not switched to the one intended by the player who intends to cheat. The player does not know when and how much the hit interval will change. Therefore, illegal games can be more reliably prevented.

The present invention may be applied as shown below.
In any of these cases, illegal play can be prevented. (B1) The counter 107c is applied when counting the count value C, but may be applied when counting the count value F instead of the free counter 105 in the first embodiment. That is, a block count process shown in FIG. 15 is executed instead of the free counter process shown in FIG. In this case, the change value N is changed by the count value F in each cycle (see steps S46 and S46 shown in FIG. 6).
48), the count value C of the counter 111 changes variously. In addition, since the player does not know the count value F in this case, the illegal game can be more reliably prevented. (B2) The counter 107c is the oscillator 10 shown in FIG.
7a, a pulse signal output from the oscillator 101 shown in FIG. 2 may be received (FIGS. 12 and 13).
In both cases, they are indicated by two-dot chain lines). In this case, the oscillator 10
The oscillation frequencies of the oscillator 1 and the oscillator 107a may be the same or different. However, it is desirable that the frequency of the oscillator 107a be higher than that of the oscillator 101.
In this case, the contact interval can be changed significantly.
Note that the oscillator 101 may have a higher frequency than the oscillator 107a. The configuration of the oscillator 101 is shown in FIG.
14A, 14B, and 14C. In this case, the pulse signal tends to change irregularly in any case. Therefore, in each of the above-described first to third embodiments, the transition period is also likely to be irregular. In this way, the hit interval can be changed irregularly. (B3) Oscillator 107a (oscillator 101) shown in FIG.
A frequency divider 107b that divides and outputs a pulse signal output from the oscillator 107a (oscillator 101) may be provided between the counter 107c and the counter 107c. This frequency divider 107b
Divides the pulse signal based on the frequency division value set from the CPU 110 (or the frame control unit 200 or the hall computer 300 or the like) via the bus 118. If the dividing value is changed to an appropriate time, the transition period expands and contracts, and the hit interval changes. (B4) It is more desirable that the set value set in the setting register 107e be set to a different value between the pachinko machines 10. For example, the I
The set value is specified based on data such as a D number and a serial number. By doing so, the counter 10
The cycle of initializing 7c (that is, the transition period and the hit interval) can be made different for each pachinko machine 10.
Therefore, even if the counting cycle of one pachinko machine is found by an unauthorized means such as a bodily sensation device, the timing cannot be adjusted because the counting cycles of other pachinko machines are different. Therefore, the possibility of "winning" with other pachinko machines is extremely low, and illegal games can be minimized. (B5) Resistor R1 shown in FIGS. 14A and 14B
It is desirable to use low accuracy capacitors 0, R12 and capacitors C10, C12, C14. The resistance R1
For 0 and R12, a carbon resistor or a metal film resistor is used. Instead of these types of resistors, a thermistor whose resistance value easily changes according to the ambient temperature may be used.
Further, variable capacitors may be used as the capacitors C10, C12, and C14. This makes it easier to make the cycle of the output pulse signal PL more irregular. Therefore, the transition period and the hit interval become more irregular. Therefore, the timing of a player attempting to play a fraudulent game can be greatly deviated, so that a fraudulent game can be prevented.

[Other embodiments] The above-described pachinko machine 1
The structure, shape, size, material, number, arrangement, operating conditions, and the like of the other parts in the main control unit 100 (control device of the gaming machine) of 0 are not limited to the above embodiment. For example, each of the following embodiments to which the above embodiment is applied may be implemented. (1) In the above embodiment, the change value N is changed at a predetermined or undefined timing. The change value N may be changed at a predetermined timing (for example, every interval Δt) based on a function. For example, the function f is defined as follows.

(Equation 1) At this time, what is given as the variable x is the count value C. In addition, the function f may be represented by a polynomial polynomial. When the change value N is changed based on such a function f, the count value C changes variously. Further, the correspondence between the data table TB2 shown in FIG. 5 and the data table TB4 shown in FIG. 6 may be a relation obtained by the function f. (2) In the above embodiment, the count value C is changed to the start value Cmi.
n and the end value Cmax (that is, Cmin ≦ C ≦
Cmax). Not limited to this mode, the starting value Cmi
It may be changed beyond the range between n and the end value Cmax.
Specifically, it can be realized by appropriately determining the function f. Even in this mode, the transition period expands and contracts, and the contact interval also changes, so that illegal play can be prevented.

(3) In the above embodiment, the "hit" in the claims is set as a big hit (step S26 shown in FIG. 4). That is, the special symbol display 42 after the change
Was applied to the state where the special symbol stopped and displayed coincided with the big hit symbol. In addition to (or instead of) this form, the "hit" may be applied to a normal hit, that is, a state in which the normal symbol displayed on the changed normal symbol display 40 is stopped and coincides with the hit symbol. Good. Even in these cases, it is possible to prevent illegal play of the pachinko machine 10 as in each embodiment. (4) In the above embodiment, the counter 11 shown in FIG.
1 was provided in the CPU 110. Instead of this mode, the count value may be stored in a recordable / updatable recording medium.
As a recording medium, a RAM 104 (indicated by a two-dot chain line in FIG. 2), a frame control unit 200, a hall computer 30
0, cards (prepaid card, IC card, paper card, etc.), printed matter on which characters, symbols, etc. are printed. This aspect of recording on the recording medium can be similarly applied to the frequency division value, the function f, and the like.

(5) The oscillator 101 outputs a pulse signal at a substantially constant cycle. Instead of the oscillator 101, an oscillator that outputs a signal other than a pulse signal (for example, an analog signal such as a sine wave signal) may be used. Further, a noise detection device that detects external noise and outputs a pulse signal may be used instead of the oscillator 101 and / or the oscillator 107a. The noise detection device includes, for example, an antenna (including a lead wire or a metal member corresponding to the antenna), an amplifier circuit for amplifying a signal received by the antenna, and an amplifier circuit for amplifying a signal received by the antenna. The signal output circuit outputs a pulse signal. (6) In the above embodiment, the count value C is changed based on the change value N (step S4 shown in FIG. 6).
0). Instead of the change value N, the count value C may be changed based on a value sent from the frame control unit 200, the hall computer 300, or the like to the pachinko machine 10 via a communication line.

(7) In the above embodiment, the counter 11
This is applied to a mode in which the count value C of 1, the count value F of the free counter 105, and the count value C of the counter 107c are all counted up. Instead of this mode, the present invention may be applied to a mode in which at least one of the count values is counted down. In this case, the count value is reduced by the change value N. The starting value is Cma
x or Nmax, and the end value is Cmin or Nmin. Therefore, the count value is initialized with Cmax or Nmax. Further, the value to be initialized is not limited to the start value and may be an arbitrary value (for example, 100). Further, the count-up and the count-down may be appropriately switched so that the count-up is performed in a certain cycle and the count-down is performed in another certain cycle. Even in these modes, the transition period expands and contracts, and the contact interval also changes. Since the contact interval changes in this way, the pachinko machine 1
0 illegal games can be prevented. (8) In the first to third embodiments, the present invention is realized by software, but may be realized by hardware. For example, there are a hardware logic circuit, a gate array, an ECL circuit, a TTL circuit, and the like. Furthermore, it can also be realized by a microprogram in firmware.

(9) In the above embodiment, the present invention is applied to the pachinko machine 10. The present invention is not limited to this, and includes a symbol display unit (normal symbol display unit 40 and / or special symbol display unit 42) capable of displaying a symbol, and a symbol stopped and displayed after the symbol is changed in the symbol display unit. Can be similarly applied to other gaming machines that provide a special benefit to a player as a win. Other gaming machines include, for example, an arrangement ball machine and a video game machine.

[0063]

As described above, the embodiments of the present invention have been described. This embodiment has not only the aspects of the invention described in the claims but also other aspects of the invention. Embodiments of the present invention will be enumerated below, and related explanations will be provided as necessary.

[Aspect 1] In the gaming machine control device according to any one of claims 1 to 7, the indeterminate timing is when a predetermined event occurs. [Interpretation of Terms in Aspect 1] The “predetermined event” refers to all events that can occur in a gaming machine, not limited to fluctuations in symbols, winning or passing of game balls to a specific area, out balls, or firing of game balls. Including. According to this aspect, when a predetermined event occurs, at least one of the start value, the end value, and the change value changes, so that the transition period and the hit interval also change. In this case, when and what values are the start value, end value,
Whether the change value is changed and the counter is initialized is unknown to the player. For this reason, it is difficult to obtain a "win" at the timing of winning or passing in the conventional counting cycle. Therefore, illegal games can be prevented.

[0065]

According to the present invention, it is possible to prevent an illegal game of a gaming machine by an illegal means such as a bodily sensation device.
