Abstract

(57) [Summary] [PROBLEMS] To prevent illegal games by illegal means such as a body sensation device. A control device for a gaming machine (for example, a pachinko machine) receives a pulse signal output from an oscillator and changes the count value of a counter regularly from a start value to an end value (step S12). However, when the specific condition is satisfied, the count value is changed to a value different from the regular change [Step S14]. By performing step S14, the period during which the count value reaches the end value is shortened. Therefore, the interval at which the count value matches a certain hit value changes. Here, even if the pachinko ball is fired according to one cycle of the counter as in the past,
The game state is not switched to the game state intended by the player trying to cheat. Further, the player does not know when and how much the length of the transition period changes. Therefore, illegal games 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 counter value is incremented by one, and when the counter 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 counter value is 0 to 298, the counter value is increased by 1 and the counter value is 2
When it is 99, 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 claim 1 receives a signal output from an oscillator, and changes a count value of a counter from a start value to an end value. The length of the period required for the count value to change from the start value to the end value is changed at least once, and when a predetermined game condition is satisfied, the gaming state of the gaming machine is changed based on the count value at that time. Switch. Here, the magnitude relationship between the “start value” and the “end value” does not matter.
That is, start value> end value, start value = end value, start value <
Any of the end values may be used. Also, the value that the counter can take is not restricted by the “start value” and the “end value”. That is, the range is not limited to the range regulated by the start value and the end value, but may exceed the range. Hereinafter, the same applies in the present specification. According to the gaming machine control device of the first aspect, a period required for the count value of the counter to change from the start value to the end value (hereinafter, referred to as a “transition period”).
Are different at least once. In this case, the interval of “hits” (including “big hits”; the same applies in the following description) changes, and it becomes difficult to match the timing of winning or passing. Further, the player does not know when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

[0008]

According to a second aspect of the present invention, a control device for a game machine according to a second aspect of the present invention receives a signal output from an oscillator and changes the count value of the counter from a start value to an end value. And when the predetermined game condition is satisfied,
The gaming state of the gaming machine is switched based on the count value at that time. According to the gaming machine control device of the present invention, when the count value of the counter is changed irregularly, the interval from the occurrence of a certain "hit" to the occurrence of the next "hit" (hereinafter, "hit interval") "). In this case, since the winning interval changes irregularly, it becomes extremely difficult to match the timing of winning or passing with the timing of "hit". Therefore, illegal games can be prevented.

[0009]

According to a third aspect of the present invention, a control device for a game machine according to a third aspect of the present invention receives a signal output from an oscillator, and counts the count of a counter from a start value to an end value. When a predetermined or indefinite timing is reached, the count value is changed differently from the regular change, and when a predetermined game condition is satisfied, the gaming state of the gaming machine is changed based on the count value at that time. Switch. According to the gaming machine control device of the third aspect, when the count value of the regularly changing counter is changed at a predetermined or undetermined timing from the regular change,
The length of the transition period also expands and contracts. This will change the hit interval, so the timing of winning or passing will be "hit"
It is difficult to match the timing. Further, since the change is made at a predetermined or indefinite timing, the player does not know when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

[0010]

According to a fourth aspect of the present invention, a control device for a gaming machine according to a fourth aspect of the present invention receives a signal output from an oscillator and regularly counts a counter value from a start value to an end value. When a predetermined or indefinite timing is reached, the count value is held for a predetermined or indefinite period, and when a predetermined game condition is satisfied, the gaming state of the gaming machine is switched based on the count value at that time. According to the gaming machine control device of the present invention, when the count value of the counter that changes regularly is held for a predetermined or indefinite period at a predetermined or indefinite timing, the length of the transition period also expands and contracts. I do. In this case, since the hit interval changes, it becomes difficult to match the timing of winning or passing with the timing of "hit". Further, since the count value is held at a predetermined or indefinite timing, the player does not know when and how long the transition period changes. Therefore, illegal games can be prevented.

[0011]

According to a fifth aspect of the present invention, a control device for a game machine according to a fifth aspect of the present invention receives a signal output from an oscillator and adjusts the count value of a counter from a start value to an end value. When a predetermined or indefinite timing is reached, the count value is changed by changing the direction of change for a predetermined or indefinite period, and when a predetermined game condition is satisfied, the game machine is changed based on the count value at that time. Switch the game state. According to the control device for a gaming machine described in claim 5, the count value of the counter that is changing regularly,
If the change direction is changed at a predetermined or undefined timing for a predetermined or undefined period, the length of the transition period also expands and contracts. In this case, since the hit interval changes, it becomes difficult to match the timing of winning or passing with the timing of "hit". In addition, since the direction of change changes at a predetermined or undefined timing, when the length of the transition period is
The player does not know how much will change. Therefore, illegal games can be prevented.

[0012]

According to a sixth aspect of the present invention, a control device for a game machine according to a sixth aspect of the present invention receives a signal output from an oscillator and changes a count value of a counter from a start value to an end value. When a predetermined or indefinite timing is reached, the start value and / or the end value are changed, and when a predetermined game condition is satisfied, the gaming state of the gaming machine is switched based on the count value at that time. According to the control device for a gaming machine described in claim 6, the count value of the counter that changes regularly within the range from the start value to the end value is:
When the start value and / or the end value are changed at a predetermined or undefined timing, the length of the transition period also increases or decreases. In this case, since the hit interval changes, it becomes difficult to match the timing of winning or passing with the timing of "hit". Further, since the range (width) to be changed changes, the player cannot know when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

[0013]

According to a seventh aspect of the present invention, a control device for a gaming machine according to a seventh aspect of the present invention receives a signal output from an oscillator, and counts a count value of a counter from a start value to an end value based on a change value. Until it reaches a predetermined or indefinite timing, the change value is changed and its count value is changed, and when a predetermined game condition is satisfied,
The gaming state of the gaming machine is switched based on the count value at that time. Here, the “change value” includes a change value for increasing the count value and a decrement value for decreasing the count value. Hereinafter, the same applies in the present specification. According to the game machine control device of the present invention, when the count value of the counter that changes regularly based on the change value is changed at a predetermined or indefinite timing, the transition period lengthens. It also stretches. This changes the contact interval,
It becomes difficult to match the timing of winning or passing with the timing of "hit". Also, since the change value changes at a predetermined or undefined timing, when the length of the transition period is
The player does not know how much will change. Therefore, illegal games can be prevented.

[0014]

According to an eighth aspect of the present invention, there is provided a game machine control device according to the first aspect of the present invention, wherein the oscillator of the game machine controls a signal to be irregular. Output. According to the control device for a gaming machine described in claim 8,
When the oscillator outputs a 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. Also, 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.

[0015]

According to a ninth aspect of the present invention, there is provided a game machine control device comprising a first counter and a second counter, and updating a first count value of the first counter. The second count value of the second counter is updated at a speed different from the speed, and when a predetermined or undetermined timing is reached, the first count value is changed based on the second count value,
When a predetermined game condition is satisfied, the game state of the game machine is switched based on the first count value at that time. here,
The “first count value” and the “second count value” are the same as the above “count value”. The “first start value” and the “second start value” are the same as the above “start value”. further,
The “first end value” and the “second end value” are the same as the above “end value”. According to the game machine control device of the ninth aspect, the first count value and the second count value are updated at different speeds, and the first count value is changed to the second count value at a predetermined or indefinite timing. You. Therefore, the first count value often changes significantly at a predetermined or undefined timing. 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. Also, 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.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. Here, Embodiments 1 to 5 show aspects realized by using a counter provided in the CPU. In the sixth embodiment,
Each of the modes realized using the counter block will be described.

[Embodiment 1] First, Embodiment 1 in which the change in the count value from the start value to the end value is diversified will be described with reference to FIGS. Here, FIG. 1 is a front view showing the appearance of the pachinko machine. FIG.
Shows a block diagram of the configuration of the first control unit. 3 shows the first main process, FIG. 4 shows the first count process (count process Pa), FIG. 5 shows the second count process (count process Pb), and FIG. FIG. 7 shows a third count process (count process Pc).
Are shown in flowcharts. FIG. 8 is a time chart showing the change over time of the count value. In these drawings, common elements are denoted by the same reference numerals.

In FIG. 1, on the game board surface 12 of the pachinko machine 10, a multifunction device 14, a first-type starting port 18, a large winning port 20 and the like are appropriately arranged and provided. Composite device 1
4, a gate sensor 38, an ordinary symbol display 40, a special symbol display 42, and the like are provided. Type 1 starting port 18
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.
8, a touch sensor 24 for detecting whether or not the player's hand is touching the handle 22, a firing motor 21 for operating the handle 22 to launch a pachinko ball, and detecting opening of the glass frame 17. 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 section 100 will be described with reference to FIG. This main control unit 100
PU (processor) 110, ROM 102, RAM 10
4, the oscillator 101, the input processing circuit 108, the output processing circuit 112, the display control circuit 114, the communication control circuit 116, and the like. The oscillator 101 outputs a pulse signal at a substantially constant cycle, and controls the operation of the CPU 110. C
The PU 110 controls the pachinko machine 10 by executing a game control program recorded in the ROM 102. The game control program includes a program for realizing a jackpot determination process described later. This ROM1
02 uses an EPROM, but may use an EEPROM, a flash memory, or the like. The RAM 104 stores various data or input / output signals. This RAM
Although a DRAM is used for 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. In addition, each of the above-described components is a bus 11.
8 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. Therefore, the start value Cmin corresponds to the lower limit, and the end value Cmax corresponds to the upper limit.

In the main processing shown in FIG. 3, it is first determined whether or not a specific condition is satisfied (step S10).
Here, the “specific conditions” are set in advance according to the type of pachinko machine, date and time, and the like. Note that the specific condition may be changed in a timely manner according to a game state or the like. In addition, as a specific example in which the specific condition is satisfied, a specific region (first type starting port 1
8)), there is a case where the pachinko ball has won or passed, or a case where a big hit has occurred. If the specific condition is satisfied (YES), a count process Pb is executed [Step S14]. On the other hand, when the specific condition is not satisfied (NO), the counting process Pa is executed [Step S12].

Here, the contents of the counting process Pa will be described with reference to FIG. Count processing Pa
Is a counter 1 provided in the CPU 110 shown in FIG.
A process of counting up the count value C of 11 by 1 is performed. In FIG. 4, first, the count value C is incremented by 1 [step S30]. That is, the calculation of C = C + 1 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 S34). That is, it is determined whether or not C ≧ Cmax is satisfied. If the count value C has reached the end value Cmax (YES), the count value C is initialized with the start value Cmin [step S36]. That is, C = Cmin is executed. At this time, the value to be initialized is not limited to the start value Cmin, and may be any other value. On the other hand, the count value C is equal to the end value Cmax.
If the count has not reached (NO), the counting process Pa ends without doing anything. In the case of this processing, the starting value Cmi
n corresponds to the lower limit, and the end value Cmax corresponds to the upper limit.

The change value X may be added to the count value C instead of or in addition to step S30 (step S32). Specifically, based on the count value N of the free counter 105 provided in the RAM 104 shown in FIG.
The change value X is acquired with reference to B2, and the change value X is added to the count value C. That is, C = C + X is executed. The correspondence between the count value N and the change value X is defined in the data table TB2, and the same applies to the data tables TB4 and TB6 described below. In this case, the change value X
May be any value, but when it is a prime number, it is more desirable in that the change of the count value C is diversified. By executing step S32, the count value C of the counter 111 can be greatly changed.

The contents of the counting process Pb will be described with reference to FIG. Counting process Pb
Is a counter 1 provided in the CPU 110 shown in FIG.
A process of counting up the count value C of the free counter 105 by the count value N of the free counter 105 within a predetermined range is performed. In FIG. 5, first, the count value C is incremented by the count value N [step S40]. That is, C
= C + N. As a result of this calculation, the count value C
Is determined to have reached the end value Cmax [Step S
44]. That is, it is determined whether or not C ≧ Cmax is satisfied. If the count value C has reached the end value Cmax (YES), the count value C is initialized with a value obtained by subtracting the end value Cmax from the count value C [Step S4]
6]. That is, C = C-Cmax is executed. On the other hand, when the count value C has not reached the end value Cmax, (N
O) terminates the count process Pb without doing anything.

It should be noted that instead of or in addition to step S40, the change value is referenced by referring to the data table TB4 based on the count value N of the free counter 105 as in step S32 shown in FIG. X may be acquired, and the change value X may be added to the count value N [Step S42]. That is, the calculation of C = C + X is executed. In step S46, the count value C
May be initialized with the start value Cmin.

Returning to FIG. 3, after counting up the count value C, a game process for a pachinko game is performed [step S16]. In this game processing, a normal symbol display 40, which is performed when a pachinko ball passes through the gate sensor 38, is used.
Such as the fluctuation processing of the special symbol display 42 performed when the pachinko ball wins the first kind starting port 18, the payout processing of the prize ball performed when the pachinko ball wins, etc.
Various processes for realizing a pachinko game are performed. One of them is a jackpot determination process, which will be described with reference to FIG. This jackpot determination process is a jackpot /
A process for determining a loss is performed.

In FIG. 6, it is determined whether or not a pachinko ball has won the first type starting port 18 (step S50).
If the pachinko ball has been won (YES), the count value C is obtained with reference to the counter 111 (step S52), and the RAM 104 (or the ROM 1) is read.
02) is obtained (step S54). Then, it is determined whether it is a big hit or not [Step S56]. Specifically, it is determined whether or not the count value C acquired in steps S52 and S54 matches the big hit value. If they match (YE
S), a jackpot process is performed [step S58]. 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. On the other hand, when the pachinko ball has not been won in the first type starting port 18 (step S
(NO at 50) or when it is not a jackpot (step S56)
NO), the jackpot process ends without doing anything.

Referring again to FIG. 3, after the game process of step S16 is completed, the count process Pc is executed until the interval Δt (for example, 4 milliseconds) elapses after the execution of step S10 is started (step S20). [Step S18]. This counting process Pc is a process for counting up the count value N of the free counter 105, and will be described with reference to FIG. In FIG. 7, first, the count value N is incremented by 1 [Step S6
0]. That is, the calculation of N = N + 1 is performed. As a result of this calculation, it is determined whether or not the count value N has reached the end value Nmax (step S64). That is, it is determined whether or not N ≧ Nmax is satisfied. If the count value N is the end value N
If the count has reached max (YES), the count value N is initialized with the start value Nmin [step S66]. That is, N = Nmin is executed. On the other hand, when the count value N has not reached the end value Nmax (NO), the count processing Pc is ended without doing anything.

It should be noted that instead of or in addition to step S60, as in step S32 shown in FIG. X may be obtained, and the change value X may be added to the count value N [Step S62]. That is, the calculation of N = N + X is executed.

Returning to FIG. 3, when the interval Δt has elapsed in step S20, the process returns to step S10.
Return to Thus, steps S10 to S20 are repeatedly executed. At this time, the count value C of the counter 111 circulates within the range from the start value Cmin to the end value Cmax and changes in the increasing direction. This will be described with reference to FIG. Here, FIGS. 8 and 9 (B), FIG.
In a time chart such as 0 (B), a change pattern P0 indicated by a solid thin line is a pattern obtained by a counting process in a conventional pachinko machine. That is,
At time t10, it starts to increase from the start value Cmin, and at time t1
In step 6, the end value Cmax is reached and the start value Cmin is initialized. Then, it starts increasing again from the start value Cmin at time t16. Thereafter, it changes in a similar manner. Therefore,
The interval at which the count value C matches a particular jackpot value (hereinafter, referred to as “jackpot interval” in the present specification) is
It is almost equal to the period from time t10 to time t16. Note that the count value C actually changes stepwise at intervals Δt as shown in the upper right circle of the drawing. In each time chart, the change of the count value C is indicated by oblique line segments in order to make the entire change pattern easy to understand.

When the main processing shown in FIG. 3 is executed, FIG.
As shown in (A), the count value C becomes a change pattern P2 indicated by a solid thick line. That is, when step S12 is executed, the time t10 is changed in the same manner as the conventional change pattern P0.
At the start value Cmin. And at time t1
2 and the specific condition is satisfied, step S14 is executed, and the count value C is greatly increased. After that, since it changes again in the same manner as the conventional change pattern P0, it reaches the end value Cmax at time t14 and is initialized to the start value Cmin.
Then, it starts to increase again from the start value Cmin at time t14, and at time t18, the specific condition is satisfied and slightly changes, and reaches the end value Cmax at time t20. Thereafter, each time the specific condition is satisfied, the count value C changes.

According to the first embodiment, the oscillator 10
The counter 111 receives the pulse signal output from
Is changed from the start value Cmin to the end value Cmax. Further, the jackpot interval in the change pattern P2 is substantially equal to the period from time t10 to time t14 in the first cycle, and substantially equal to the period from time t14 to time t20 in the second cycle. The length of the period required for the count value C to change from the start value Cmin to the end value Cmax (ie, the transition period) is 1
It will expand and contract one or more times. As a result, at least one time is different from other periods. When the big hit symbol is displayed on the special symbol display 42 (predetermined game condition is satisfied), the game state of the pachinko machine 10 is switched by opening the lid 20a of the special winning opening 20.
Therefore, even if the pachinko ball is fired in synchronization with one cycle of the counter as in the related art, a game state intended by a player who intends to cheat (a big hit state in this example. The same applies hereinafter). ) Does not switch. The player does not know when and how long the transition period will change. Therefore, illegal games can be prevented.

Further, the specific condition may or may not be satisfied once or more than once, and the count value N of the free counter 105 changes in a complicated manner according to the game state. Thus, the number of times the specific condition is satisfied and the count value N
In some cases, the count value C of the counter 111 changes irregularly. Since the jackpot interval changes in a complicated manner (that is, variously), it becomes extremely difficult to match the timing at which the pachinko ball is made to enter the first-type starting port 18 with the jackpot timing. Therefore, illegal games can be prevented. Further, at an undefined timing, the count value C changes differently from a normal change (for example, times t12 and t18 shown in FIG. 8A). At this time, the width of change of the count value C also depends on the count value N of the free counter 105. Therefore, the player does not know when and how long the transition period changes. Therefore, illegal games can be prevented.

The present invention may be applied as described below.
In any of these cases, illegal play can be prevented. (A1) The length of the transition period may be changed only once compared to the other transition periods, and thereafter, may be changed according to the length of the other transition period. Even in this case, the player does not know how much the jackpot interval has changed. (A2) The specific condition may be satisfied at a predetermined timing (for example, after a lapse of a predetermined period from when the count value C is the start value Cmin). Even in this case, the player cannot know how much the jackpot interval has changed depending on the count value N of the free counter 105. (A3) When the specific condition is satisfied at an indefinite timing, instead of the count value N of the free counter 105,
A predetermined value stored in the ROM 102 (or RAM 104) may be added (or subtracted) to the count value C. Even in this case, it is not known how much the count value C changes from a normal change. Therefore, the player does not know how much the jackpot interval has changed. (A4) As shown in FIG. 8B, the count value C may be reduced based on the count value N at times t24 and t26 at which the specific condition is satisfied. In this case, time t1
At 0, it starts to increase from the start value Cmin, and the time t
It decreases at 24 and 26, reaches the end value Cmax at time t28, and is initialized to the start value Cmin. The jackpot interval in the change pattern P4 is from time t10 to time t10.
Equal to a period of up to 28. In this embodiment, the jackpot interval is longer than before. Since the jackpot interval changes in this manner, it becomes difficult to match the timing of winning the pachinko ball to the first-type starting port 18 with the timing of the jackpot. The mode of increasing the count value C based on the count value N and the mode of decreasing the count value illustrated in FIG. 8A may be appropriately mixed. In this case, the jackpot interval changes more complicatedly depending on the degree of coexistence, the increase value, the decrease value, and the like. For this reason, it is more difficult to match the timing at which the pachinko ball is won to the first-type starting port 18 with the timing of the jackpot.

[Second Embodiment] Next, a second embodiment in which the change of the count value from the start value to the end value is temporarily stopped will be described with reference to FIG. Here, in FIG. 9, FIG. 9 (A) shows a flowchart of the second main processing, and FIG. 9 (B) shows a time-dependent change of the count value in a time chart. The configurations of the pachinko machine 10 and the main control unit 100 are the same as those of the first embodiment.
Therefore, the description is omitted. Therefore,
The points different from the first embodiment will be described.

The main process shown in FIG. 9A is a process replacing the main process shown in FIG. In FIG. 9A, first, it is determined whether or not a specific condition is satisfied (step S10). If the specific condition is not satisfied (N
O), the counting process Pa is executed [Step S1
2]. Thereafter, a game process for a pachinko game is performed [Step S16]. On the other hand, when the specific condition is satisfied (YES), the game process is performed without doing anything [Step S
16]. Then, it waits until the interval Δt elapses after the execution of step S10 is started [step S2
0], and returns to step S10. Thus, step S1
0, S12, S16, and S20 are repeatedly executed.

When the main processing shown in FIG. 9A is executed, the count value C becomes a change pattern P6 indicated by a solid thick line as shown in FIG. 9B. That is, step S
When step 12 is executed, the value increases from the start value Cmin at time t10. Then, from time t30 to time t32, the specific condition is satisfied and step S12 is not executed, and the count value C is held. After that, it increases again, reaches the end value Cmax at time t34, and starts at the start value Cmin.
Is initialized to Then, again at time t34, the start value Cmi
Start increasing from n. Thereafter, every time the specific condition is satisfied, the count value C is held. This change pattern P6
Is approximately equal to the period from time t10 to time t34. In this embodiment, since the count value C is held between the time t30 and the time t32, the jackpot interval is longer than before.

According to the second embodiment, the count value C is held at an undefined timing for an undefined period. Therefore, the transition period is extended and the jackpot interval is also changed.
Since the jackpot interval changes in this manner, as in the first embodiment, it is possible to prevent the pachinko machine 10 from illegally playing. Note that the timing held by the count value C may be a predetermined timing. Similarly, the period during which the count value C is held may be a predetermined period. In either case, the transition period will extend and the jackpot intervals will change,
Unauthorized games can be prevented.

Third Embodiment Next, a third embodiment in which the direction of change is temporarily changed until the count value reaches the end value from the start value will be described with reference to FIG. Here, in FIG. 10, FIG.
Is shown in a flowchart, and FIG. 10B is a time chart showing a change over time of the count value.
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.

The main process shown in FIG. 10A is a process replacing the main process shown in FIG. In FIG. 10A, first, it is determined whether a specific condition is satisfied (step S10). If the specific condition is satisfied (YE
S), after inverting the sign of the change value X [Step S1
1], and executes a count process Pa [Step S1
2]. On the other hand, when the specific condition is not satisfied (NO),
The count process Pa is executed without doing anything [Step S1
2]. After executing step S12, a game process for a pachinko game is performed [step S16]. Then, it waits until the interval Δt has elapsed from the start of the execution of the step S10 (step S20), and returns to the step S10. Thus, steps S10, S11, S12, S1
6, S20 are repeatedly executed.

When the main process shown in FIG. 10A is executed, the count value C becomes a change pattern P8 indicated by a solid thick line as shown in FIG. 10B. That is, when step S12 is executed, the start value Cmin is obtained at time t10.
To increase from. Then, at times t40 and t42, the specific conditions are satisfied, and step S11 is executed.
The sign of the change value X has changed. Therefore, at time t10
To t40 and times t42 to t44 increase in time,
From 40 to t42, the count value C changes in the decreasing direction. Thereafter, at time t44, the end value Cmax is reached and the start value Cmin is initialized. Then, it starts increasing again from the start value Cmin at time t44. Thereafter, each time the specific condition is satisfied, the sign of the change value X changes, and the count value C increases or decreases. The jackpot interval in this change pattern P8 is substantially equal to the period from time t10 to time t44. In this example, it is time t16 that the count value C is restored to the same value as the count value C at time t40.
For this reason, the jackpot interval is longer than before by the period from time t40 to time t16.

According to the third embodiment, the count value C is changed at an undefined timing by changing the change direction for an undefined period. Therefore, the transition period is extended and the jackpot interval is also changed. Since the jackpot interval changes in this manner, as in the first embodiment, it is possible to prevent the pachinko machine 10 from illegally playing. The timing at which the direction of change of the count value C is changed may be a predetermined timing. Similarly, the period during which the count value C is held may be a predetermined period. In either case, the transition period is extended,
Since the jackpot interval also changes, illegal games can be prevented.

[Fourth Embodiment] Next, a fourth embodiment for changing the start value and / or the end value will be described with reference to FIGS.
This will be described with reference to FIG. Here, FIG. 11 is a flowchart showing the fourth main process. FIG. 12, FIG.
3 shows a time chart of the change over time of the count value. The pachinko machine 10 and the main control unit 1
Since the configuration of 00 is the same as that of the first embodiment, its description is omitted. Therefore, points different from the first embodiment will be described.

The main processing shown in FIG. 11 is an alternative to the main processing shown in FIG. In FIG. 11, first, a count process Pa for counting up the count value C of the counter 111 by 1 is executed [Step S12], and thereafter, a game process for a pachinko game is performed [Step S12].
16]. Then, from the start of execution of step S12, until the interval Δt elapses (step S20), a count process Pc for counting up the count value N of the free counter 105 by 1 is executed [step S1].
8]. When the interval Δt has elapsed, it is determined whether or not the count value C has reached the end value Cmax [Step S2
2]. That is, it is determined whether or not C ≧ Cmax is satisfied. If the count value C has reached the end value Cmax (YES), the start value Cmin and / or the end value Cmax are changed based on the count value N [step S2].
4]. That is, Cmin = Cmin + N, Cmin = Cmin
At least one of -N, Cmax = Cmax + N, Cmax = Cmax-N is executed. After execution of step S24, or when the count value C has not reached the end value Cmax (NO in step S22), the process returns to step S12. Thus, steps S12, S16, S18, S2
0, S22, and S24 are repeatedly executed.

In the main process shown in FIG. 11, when the end value is changed by executing Cmax = Cmax + N in step S24, as shown in FIG. Become. That is, when step S12 is executed, the value increases from the start value Cmin at time t10, and ends at (tma) at time t50.
x + N) and is initialized to the starting value Cmin. Then, it starts increasing again from the start value Cmin at time t50.
The jackpot interval in the change pattern P10 is substantially equal to the period from time t10 to time t50. In this example, the jackpot interval is longer than before by the end value of the count value N. Similarly, in step S24, C
When the end value is changed by executing max = Cmax-N, the count value C becomes a change pattern P12 indicated by a solid thick line as shown in FIG. In this example, the jackpot interval is shorter than before by the end value of the count value N.

In step S24, Cmin = Cmi
When the end value is changed by executing n + N, FIG.
As shown in (A), the count value C becomes a change pattern P14 indicated by a solid thick line. In this example, the jackpot interval is shorter than before by the end value of the count value N.
Further, when the end value is changed by executing Cmin = Cmin-N in step S24, the count value C becomes a change pattern P indicated by a solid thick line as shown in FIG.
It becomes 16. In this example, the jackpot interval is longer than before by the end value of the count value N.

According to the four aspects of the fourth embodiment, when the count value C reaches the end value Cmax (predetermined timing), the start value Cmin and / or the end value C
max is changed. Therefore, the transition period expands and contracts, and the jackpot interval also changes. Since the jackpot interval changes in this manner, similarly to the first embodiment, the pachinko machine 10
Illegal game can be prevented. Note that these 4
If the two modes are arbitrarily mixed, the jackpot interval changes more variously. Further, even when the start value and the end value are changed at the same time, the jackpot interval also changes more variously. Further, the start value Cmin and / or the end value Cmax may be changed at an undefined timing. In either case, the transition period expands and contracts, and the jackpot interval also changes, so that illegal games can be prevented.

Fifth Embodiment Next, a fifth embodiment in which the change value (change rate) of the count value is changed will be described with reference to FIGS.
This will be described with reference to FIG. Here, FIG. 14 is a flowchart showing the fifth main process. FIG. 15 is a time chart showing a change over time of the count value. 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.

The main process shown in FIG. 14 is a process replacing the main process shown in FIG. In FIG. 14, first, a count process Pb for counting up the count value C of the counter 111 based on the change value X is executed [Step S
14] Then, a game process for a pachinko game is performed [Step S16]. Then, the count value N of the free counter 105 is set to 0.
A count process Pc for counting up by 1 (may be another real value such as 0.01) is executed [Step S18]. When the interval Δt has elapsed, it is determined whether or not the count value C has reached the end value Cmax (step S22). That is, it is determined whether or not C ≧ Cmax is satisfied. If the count value C has reached the end value Cmax (YES), the change value X is changed based on the count value N [step S26]. That is, X = N is executed. After execution of step S26, or when the count value C has not reached the end value Cmax (NO in step S22), the process returns to step S14. Thus, step S1
4, S16, S18, S20, S22, and S26 are repeatedly executed.

When the main processing shown in FIG. 14 is executed, the count value C becomes a change pattern P18 shown by a solid thick line as shown in FIG. That is, step S1
When Step 2 is executed, the value increases from the start value Cmin at time t10 in accordance with the change value X (where X> 1). At time t70, the end value Cmax is reached and the start value Cmin is reached.
Is initialized to Then, again at time t70, the start value Cmi
n, and at time t72, the end value Cmax
Reach The jackpot interval in the change pattern P18 is substantially equal to the period from time t10 to time t70 in the first cycle, and substantially equal to the period from time t70 to time t72 in the second cycle. In this example, the jackpot interval is shorter than before in any of the periods. On the other hand, when the change value X is 0 <X <1, FIG.
As shown in (B), the count value C becomes a change pattern P20 indicated by a solid thick line. The jackpot interval in the change pattern P20 is substantially equal to the period from time t10 to time t74. In this example, the jackpot interval is longer than before.

According to the fifth embodiment, when the count value C reaches the end value Cmax (predetermined timing), the change value X is changed to change the count value C. Therefore, the transition period expands and contracts, and the jackpot interval also changes. Since the jackpot interval changes in this manner, as in the first embodiment, it is possible to prevent the pachinko machine 10 from illegally playing. Note that the timing at which the change value X is changed may be an indefinite timing. Also in this case, the transition period expands and contracts, and the jackpot interval also changes, so that an illegal game can be prevented.

[Sixth Embodiment] Next, a sixth 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. 16 is a block diagram showing the configuration of the second control unit. FIG. 17 shows the configuration of the counter block. FIG. 18 shows the configuration of the oscillator. FIG. 19 is a flowchart showing the processing performed in the counter block. Since the configuration of the pachinko machine 10 is the same as that of the first embodiment,
The description is omitted. Therefore, points different from the first embodiment will be described.

The main control unit 100 shown in FIG.
Is a control unit replacing the main control unit 100 shown in FIG. FIG.
The difference is that the counter is realized by the counter block 106. The configuration of the counter block 106 is shown in FIG. In FIG. 17, the counter block 106 comprises 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 N. The counter 107c receives the clear signal output from the setting register 107e, and initializes the counter with a start value Nmin. Further, the counter 107c receives the read signal output from the CPU 110 via the bus 118, and sends the count value N at that time 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 Nmax. The comparator 107d outputs a clear signal when the count value N of the counter 107c matches the set value of the setting register 107e, and does not output anything when they do not match.

FIG. 18 shows an example in which the oscillator 107a is constituted by a self-excited oscillation circuit. Here, FIG. 18A shows a circuit configuration of an oscillator using a crystal oscillator, and FIG.
FIG. 18B shows a circuit configuration of an oscillator using a resistor and a capacitor, and FIG. 18C shows a circuit configuration of an oscillator in which inverters are connected in multiple stages.

The oscillator shown in FIG. 18A 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. 18B comprises 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. 18C 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.

Counter block 106 having the above configuration
Are processed in the procedure of the count process Pd shown in FIG. This count process Pd is executed instead of the count process Pc shown in FIG. In FIG. 19, first, it is determined whether or not a pulse signal output from the oscillator 107a has been received (step S70). If no pulse signal has been received (NO), the process proceeds to step S80 without doing anything. In this case, the count value N of the counter 107c remains held. On the other hand, if a pulse signal has been received (YES in step S70), it is determined whether a stop signal has been received from the CPU 110 [step S72]. If a stop signal is received (YES), step S8
Go to 0. Also in this case, the count value N of the counter 107c
Remains held. On the other hand, when the stop signal has not been received (NO in step S72), the count value N is counted up (step S74). Specifically, N
= N + 1 is performed. Then, it is determined whether or not the count value N has reached the end value Nmax (step S76).
Specifically, it is determined whether or not N ≧ Nmax is satisfied. If the count value N reaches the end value Nmax (YE
S), the count value N is initialized with a start value Nmin [step S78]. Specifically, substitution of N = Nmin is performed. The start value Nmin is set in the counter 107c directly from the CPU 110 in advance. The value of the start value Nmin may be changed as needed. On the other hand, when the count value N has not reached the end value Nmax (NO in step S76), the process proceeds to the next step S80 without doing anything.

Next, it is determined whether a clear signal has been received from the comparator 107d (step S80). If the clear signal has not been received, the process proceeds to step S84. Also in this case, the count value N of the counter 107c remains held. On the other hand, when a clear signal is received, (YE
S), similarly to step S78, the count value N of the counter 107c is initialized with the start value Nmin [step S8]
2]. Then, it is determined whether or not a read signal has been received from the CPU 110 (step S84). If the read signal has not been received (NO), the process returns to step S70. On the other hand, when a read signal is received (YES), bus 1
After the count value N is sent to the CPU 110 via 18 [Step S86], the process returns to Step S70. With this processing content, the count value N is normally counted up in step S74, and the CPU 110
A readout signal is output to 07c to obtain count value N. When the count-up is stopped and the count value N is held, a stop signal may be output to the counter 107c. Further, the start value Nmin can be set in the counter 107c and the end value Nmax can be set in the setting register 107e, and can be changed. Therefore, the start value Nmin and / or the end value Nmax can be changed as appropriate.

According to the sixth embodiment, the oscillator 10
1 (the first oscillator) receives the pulse signal output from the
The count value C (first counter) of the counter 111 (first counter)
The count value) is changed regularly from the start value Cmin (first start value) to the end value Cmax (first end value) (see FIG. 3). The counter 107c (second counter) receives a pulse signal output from the oscillator 107a (second oscillator) that operates faster than the oscillator 101.
Is changed from the start value Nmin (second start value) to the end value Nmax (second end value) (see FIG. 19). Therefore, the count value C of the counter 111 and the count value N of the counter 107c are updated at different speeds. And
At an undefined timing, the count value N of the counter 107c
(Step S14 shown in FIG. 3). Therefore, the count value C often changes greatly at an undefined timing. Further, when the big symbol is displayed on the special symbol display 42 (predetermined game condition is satisfied), the lid 2 of the special winning opening 20 is opened.
The game state of the pachinko machine 10 is switched by opening 0a. Here, since the oscillator 107a is constituted by the self-excited oscillation circuit shown in FIG. 18, the interval between the pulse signals PL is not so high in accuracy and becomes non-uniform. This tendency becomes more remarkable as the oscillator 107a with lower accuracy is used.
Also, the cycle of initializing the counter 107c (corresponding to a transition period) is also non-uniform. Therefore, the count value N obtained by executing steps S74 and S82 shown in FIG. 19 also becomes non-uniform. Furthermore, since the jackpot intervals are not 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. Not surprisingly, for the player,
I don't know how much it will change. Therefore, illegal games can be more reliably prevented.

Note that the present invention may be applied as shown below.
In any of these cases, illegal play can be prevented. (B1) The counter 107c is the oscillator 10 shown in FIG.
Instead of 7a, a pulse signal output from the oscillator 101 shown in FIG. 2 may be received (in FIG. 16 and FIG. 17, indicated by a two-dot chain line). In this case, the oscillation frequencies of the oscillator 101 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 jackpot interval can be significantly changed.
Note that the oscillator 101 may have a higher frequency than the oscillator 107a. Further, the configuration of the oscillator 101 may be any one of the three modes shown in FIG. In this case, the pulse signal is likely to change irregularly. Therefore, in each of the above-described first to fifth embodiments, the transition period is also likely to be irregular. In this way, the jackpot interval can be changed irregularly. (B2) 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
Performs the frequency division of the pulse signal based on the frequency division value set via the bus 118 from the CPU 110 (or the frame control unit 200 or the hall computer 300 or the like). If the dividing value is changed at an appropriate time, the transition period expands and contracts, and the jackpot interval also changes. (B3) 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 jackpot 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. (B4) The resistor R1 shown in FIGS. 18A and 18B
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 jackpot 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] In the control device for a gaming machine described above, the structure, shape, size, material,
The number, arrangement, operating conditions, and the like 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 fifth embodiment, the change value X is changed at a predetermined or undefined timing. This change value X is determined at a predetermined timing (for example, interval Δt
Each time). For example, the function f is defined as follows.

F = Ae ^Bx + C (e is natural logarithm, A, B, C
Is a constant and x is a variable.) 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 X is changed based on such a function f, for example, a change pattern P22 shown in FIG. 20 is obtained. In this example, the first cycle from time t10 to time ta2 and the second cycle from time ta2 to time ta4 are changed based on different functions f. In any case, the transition period expands and contracts, and the jackpot interval also changes, so that illegal play can be prevented. Note that the change value X may be changed based on the same function f. Further, the correspondence in the data table TB2 shown in FIG. 4, the data table TB4 shown in FIG. 5, and the data table TB6 shown in FIG. By doing so, it is not necessary to perform the calculation every time, and the processing speed is improved.

(2) In each of the above embodiments, the count value C is changed within the range between the start value Cmin and the end value Cmax (that is, Cmin ≦ C ≦ Cmax). The present invention is not limited to this mode, and may be changed beyond the range between the start value Cmin and the end value Cmax. Specifically, it can be realized by appropriately determining the function f. An example is shown by a change pattern P24 in FIG. In this example, the count value C is greater than the end value Cmax between time tb2 and time tb4. Also in this case, the transition period expands and contracts,
Since the jackpot interval also changes, illegal games can be prevented.

(3) In the first embodiment, when the specific condition is satisfied, the count value C is reduced based on the count value N, and the time when the count value C reaches the end value Cmax is not limited ( FIG. 8 (B)). Instead of this mode, the time when the count value C reaches the end value Cmax may be limited to a certain period. An example is shown by a change pattern P26 in FIG. In this example, time tc0, tc2, t
At c4, tc6, and tc8, the count value C decreases, and the count value C is initialized with the start value Cmin in a cycle corresponding to the period from time t10 to time t16. In this case, the number of times that the count value C matches the hit value Hit during a certain period changes, and the period from one hit to the next hit changes. Therefore, 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 a game state intended by a player who intends to cheat. The player does not know when and how long the transition period will change. Therefore, illegal games can be prevented.

(4) In each of the above embodiments, the "hit" in the claims is a large hit. That is, the present invention was applied to a state where the special symbol stopped and displayed on the special symbol display 42 after the change matched 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 and stopped on the changed ordinary symbol display 40 matches the hit symbol. Even in these cases, as in each embodiment, the pachinko machine 1
0 illegal games can be prevented. (5) In the first embodiment, the counter 111 is provided in the CPU 110 in FIG. Instead of this form,
The count value may be stored in a recordable / updateable recording medium. As the recording medium, the RAM 104 (indicated by a two-dot chain line in FIG. 2), the frame control unit 200, the hall computer 3
00, cards (prepaid cards, IC cards, paper cards, etc.), printed matter on which characters, symbols, etc. are printed. The recording on the recording medium is performed by dividing the frequency or the function f.
Etc. can also be applied.

(6) 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. This 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 when the amplified signal reaches a predetermined level. The signal output circuit outputs a pulse signal. (7) In each of the above embodiments, the free counter 105
The count value C is changed based on the count value N (for example, step S14 shown in FIG. 3). Instead of the count value N, the frame control unit 200 or the hall computer 3
The count value C may be changed based on the count value sent to the pachinko machine 10 from 00 or the like via the communication line.

(8) Each of the above embodiments is applied to a mode in which the count value C of the counter 111, the count value N of the free counter 105, and the count value N 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 decremented by 1 or N or the change value X. Also, the starting value is Cmax or Nmax,
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 jackpot interval also changes. Since the jackpot interval changes in this way, it is possible to prevent illegal play of the pachinko machine 10. Further, the counter may be a k-ary n-digit counter and the value accessible from the CPU 110 or the like is m-digit. Where k,
n and m are integers, and k> 1, n> 1, n>
The relationship of m> 1 holds. In this case, initialization is performed within the range of m digits. For example, four decimal digits (k = 1
0, n = 4) when using a counter of 0000-9
999. At this time, if the value accessible from the CPU 110 or the like is three digits (m = 3), the possible values are 000 to 999. In this example, when the counter counts up after 0999, it becomes 1000. However, when viewed from the CPU 110 or the like, the counter is initialized from 999 to 000. This is the same when counting down. As described above, even if the counter is not actively initialized by the clear signal or the like, the CPU 11
The value obtained by 0 or the like can be initialized. The same applies to the case where a counter in which at least one digit of the n-digit counter is another progressive number is applied. For example, there is a counter in which the lower two digits of a 5-digit decimal counter are counted in a binary number. Also, as in the sixth embodiment, the oscillator 1
It is more preferable that the pulse signal output from the counter 07a be divided by the frequency divider 107b and sent to the counter (see FIG. 17), since the count cycle changes variously.

(9) In the first to fifth 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. (10) In the above embodiments, the hit value (including the big hit value) is not changed, but the hit value may be changed at a predetermined or indefinite timing. In this case,
The timing at which the count value coincides with the hit value varies from the start value to the end value. Therefore, the period from one hit to the next will change,
Even if a pachinko ball is fired in accordance with one cycle of the counter as in the related art, the game state is not switched to a game state intended by a player who intends to cheat. The player does not know when and how long the transition period will change. Therefore, illegal games can be prevented.

(11) In each of the above embodiments, 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.

A gaming machine control device that switches the gaming state of the gaming machine based on the gaming machine. [Relevant Description of Aspect 1] According to this aspect, if the count value of the counter is changed irregularly, the hit interval also changes. In this case, since the winning interval changes irregularly, it becomes extremely difficult to match the timing of winning or passing with the timing of "hit". Therefore, illegal games can be prevented.

[Aspect 2] In response to a signal output from the first oscillator, the first count value of the first counter is changed regularly from the first start value to the first end value, and the first oscillator In response to a signal output from the second oscillator operating at a higher or lower speed, the second counter value of the second counter is changed from the second start value to the second end value, and at a predetermined or indefinite timing When it reaches, its second
A game machine control device that changes a first count value based on a count value and, when a predetermined game condition is satisfied, switches a game state of the game machine based on the first count value at that time. According to this aspect, when the first count value of the first counter that is changing regularly is changed to the second count value of the second counter at a predetermined or indefinite timing, the first count The length of the transition period in the counter also expands and contracts. In this case, since the hit interval in the first counter changes, it becomes difficult to match the winning timing. Further, since the change value changes at a predetermined or indefinite timing, the player does not know when and how long the transition period changes. Therefore, illegal games can be prevented.

[Mode 3] In the control device for a gaming machine according to mode 2 or claim 9, the first oscillator and / or
Alternatively, the second oscillator is a gaming machine control device that outputs signals irregularly. [Relevant Description of Aspect 3] According to this aspect, the first oscillator and / or the second oscillator allow the first counter of the first counter to operate.
The count value and / or the second count value of the second counter changes irregularly. When the first count value is changed to the second count value at a predetermined or indefinite timing, the length of the transition period in the first counter also expands and contracts. In this case, since the hit interval in the first counter further changes, it becomes extremely difficult to match the winning timing. Further, since the change value changes at a predetermined or indefinite timing, the player does not know when and how long the transition period changes. Therefore, illegal games can be more reliably prevented.

[Aspect 4] Upon receiving the signal output from the oscillator, the count value of the counter is changed from the start value to the end value, and the count value becomes a hit value and then becomes the next hit value. The length of the period until at least one time, the predetermined game conditions are satisfied, and,
A game machine control device that switches the game state of the game machine when the count value matches the hit value. [Relevant Description of Aspect 4] According to this aspect, the timing at which the count value coincides with the hit value from the start value to the end value differs at least once. Therefore, the period from one hit to the next hit changes, so that even if the pachinko ball is fired in accordance with one cycle of the counter as in the past, the player who intends to cheat is intended. It does not switch to the gaming state. The player does not know when and how long the transition period will change. Therefore, illegal games can be prevented.
