Abstract

PROBLEM TO BE SOLVED: To prevent illegal acts committed by the addition of an illegal board to a game controller attached to a game machine and used for selecting a special playing condition, or the like. SOLUTION: A pulse signal unoutputting state under which no pulse signal for every predetermined judging counter incrementing time is outputted to a display controller is provided. Therefore, since the value of a false counter Gc which counts every pulse signal on an illegal board differs from the value of the judging counter Hc, no game ball detection signal can be outputted to a game controller when the value of the judging counter Hc is a specific value, so that the act of illegally bringing about a special playing condition can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game control device for selecting a special game state or the like provided in a gaming machine, and to preventing illegal acts by attaching an illegal board to the game control device.

[0002]

2. Description of the Related Art Conventionally, pachinko machines as gaming machines include:
A symbol display capable of variably displaying a plurality of symbols is arranged substantially at the center of the game area. Then, when the game ball wins the winning opening, a prize ball is paid out, the winning winning opening is won, the game ball detector passes through a specific area, the game ball detector generates a game ball detection signal, and the signal is displayed according to the signal. There is a type in which the design of the container is variably displayed. Control of this kind of pachinko machine mainly includes a game control device, a display control device for controlling a symbol display of a symbol display device, a game ball detector for generating a game ball detection signal, as shown in FIG. It is composed of a relay board and the like. This game control device has a CPU (CENTR
ROM (READ ONLY MEMOR) that stores AL PROCESSOR UNIT and game program
Y) is provided. In addition, the display control device displays a symbol on a liquid crystal symbol display according to a signal from the CPU.

[0003] The pachinko machine having the above-described configuration generates a special game state based on a well-known determination method.
One such method will be described. The game program is initialized at the same time as power-on, and is initialized for a predetermined time (2 ms).
Each time, a determination counter Hc for adding 1 is provided, and this determination counter Hc corresponds to the probability of the special game state,
For example, for a probability of 1/330, a cyclic counter of 0 to 329 (number) is used. Further, the game control device generates a pulse signal every 2 ms for adding 1 to the determination counter Hc, and this pulse signal is transmitted to the terminals A and B of the game control device.
Are output to the terminals a and b of the display control device via the terminal, and the timing of symbol display on the symbol display is set, and the other terminals are used for signals such as selection of display symbols.

[0004] When a game ball passes through a specific area after winning a start winning prize port installed in the game area, it is detected by a game ball detector. The game ball detection signal is output to the terminals c and d of the relay board via the terminals C and D of the game ball detector, and the output signal from the relay board is output to the game control device. Then, the value of the determination counter Hc at the time of the falling of the game ball detection signal is stored, it is determined whether or not this stored value causes a special game state, and a symbol is displayed on a display control device (symbol display). Send a signal to start the fluctuation. When the stored value is a specific value (for example, “7”), after a predetermined time, the same symbol (special symbol) is fixedly displayed on the symbol display unit to generate a special gaming state that is advantageous to the player. .

[0005]

On the other hand, as illegal means, as shown in FIG. 2 (B), a circuit configuration is made via an illegal board on which cpu, rom for storing illegal software, etc. are arranged. That is, the output signals from the terminals A and B of the game control device are input via the terminals A 'and B' of the illegal board.
Further, the terminals C and D of the game ball detector are detached from the relay board and connected to the terminals C 'and D' of the unauthorized board, and the terminals e and f of the unauthorized board and the terminals c and d of the relay board are connected to each other. Connecting.

In the above configuration, it is assumed that the value of the determination counter Hc in the gaming machine is 0 to
It has been investigated in advance that the number of circulations is 329, and the specific value of the special game state is “7”. Then, the player plays the game as usual, but is controlled by software as described below. That is, the cpu of the improper board performs a process of adding 1 to the pseudo counter Gc every time a pulse signal generated every 2 ms for adding 1 to the determination counter Hc is received via the terminals A and B of the game control device. . As a result of this processing, the pseudo counter Gc on the unauthorized board becomes the same value (0 to 329) as the determination counter Hc.

[0007] Then, a player who plays illegally counts an unusual game, for example, a game ball detection signal, and
After that, pause the game for a certain time (for example, 3 minutes)
The game is started again, and then the game ball wins the starting winning opening, and the game ball detection signal from the game ball detector is counted.
Min) Pause, so-called set hitting. When the set is performed a predetermined number of times, the set is completed.
Then, when the game ball wins the starting winning opening, passes through the specific area, and detects the game ball detection signal from the game ball detector, the value is not immediately output to the relay board and the value of the pseudo counter Gc is " The falling signal is output from the terminals e and f of the unauthorized board to the terminals c and d of the relay board shortly before “7” is reached. Then, the determination counter Hc generates a special game state, assuming that a game ball detection signal is output from the game ball detector. As described above, the cpu on the illegal board is output to the determination counter Hc at the timing of the special game state while comparing the game ball detection signal from the symbol display with the value of the pseudo counter Gc. A game state can be created.

[0008] As described above, the software based on the illegal board controls at first glance the game as if it were playing normally, so that the clerk cannot easily determine whether or not the illegal action has taken place. Because it is small, it is not easy to find out whether or not an illegal board is attached from the back of the gaming machine.
Therefore, the present invention provides a gaming machine capable of preventing illegal acts even when such an illegal substrate is attached.

[0009]

According to a first aspect of the present invention, there is provided a gaming machine, comprising: a symbol display capable of variably displaying a plurality of symbols; a gaming ball detector for detecting that a gaming ball has passed a specific area; A game control device having a determination counter for adding every predetermined time from the time is arranged, and this game control device outputs a pulse signal to the display control device for controlling the symbol display every predetermined time, and a game ball detector. When the value of the determination counter when a game ball is detected is a specific value, the symbol display is a gaming machine that displays a special symbol and generates a special game state, and displays a pulse signal. A pulse signal non-output state that is not output to the device is provided. Therefore, the cpu on the illegal board is counted as the pseudo counter Gc for each pulse signal sent to the display control device, but the pulse signal is not sent while the pulse signal non-output state is maintained. Judgment counter Hc
Value. As a result, the value of the pseudo counter Gc cannot specify the value Hc (specific value) of the determination counter that causes the special game state. That is, when the value of the determination counter Hc is a specific value, a game ball detection signal cannot be output to the game control device, and the occurrence of an illegal special game state can be prevented.

In the gaming machine of the present invention, the pulse signal non-output state is released by detecting the game ball by the game ball detector, so that the pulse signal is counted thereafter, and the value of the determination counter and Different. Claim 3
When the power of the gaming machine is turned on, the initial value of the judgment counter is selected through the initial value selecting means. Therefore, even if the pulse signal generated every predetermined time is counted, it differs from the value of the judgment counter. When the value of Hc is a specific value,
A game ball detection signal cannot be output to the game control device, and the occurrence of an illegal special game state can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pachinko machine as a gaming machine is of a well-known type, and is related to the gist of the present invention with reference to a front view shown in FIG. 1 and a control block diagram shown in FIG. Will be described. Near the center of the game area 19,
A liquid crystal display type symbol display L for performing a variable display game through a plurality of variable symbols is arranged.
Is a CPU (CENTER) provided in a game control device described later.
AL PROCESSER UNIT) and the display control device connected to the game control device, the symbol display portion L1
To L3, and symbols "0 to 9, A to F" are variably displayed in this order.

On the left and right sides of the symbol display L, ordinary symbol start gates 23a and 23b are provided, and when a game ball passes, the ordinary symbol display 5 attached to a special winning opening 58 described later.
The symbol 6 starts to fluctuate, stops after a lapse of a predetermined time, and hits when the finalized symbol coincides with a preset symbol, and the ordinary electric accessory 57 is opened for a predetermined time. And
When a game ball passes the specific area after winning the ordinary electric accessory 57, a game ball detector (not shown) for detecting the winning ball generates a game ball detection signal, which will be described later in detail. It is determined whether or not a special game state or the like occurs.

FIG. 2A is a block diagram for controlling a pachinko machine, and has a game control device having the same configuration as that of the related art.
It is composed of a display control device that controls the symbol display of the symbol display, a game ball detector that generates a game ball detection signal, a relay board, and the like. This game control device has a CPU (CENTRAL
(PROCESSOR UNIT) and a ROM (REA) storing a game program capable of preventing fraud.
D ONLY MEMORY).

The game program includes a determination counter Hc which is a cyclic counter of 0 to 329 which adds 1 every reset time (2 ms) of the CPU, and a pulse signal generated at each reset time (predetermined time). Is output to the terminals a and b of the display control device via the terminals A and B of the game control device, and the timing of symbol display on the symbol display is set, and the other terminals are used for selecting a display symbol and the like. Used for signals. The predetermined time (2 ms) is
This is the time during which the entire game software can be executed.

When a game ball wins a start winning prize port installed in the game area and passes through a specific area, a game ball detector for detecting the game ball generates a game ball detection signal (symbol start signal), This game ball detection signal is supplied to terminal C of the game ball detector,
The signal is output to terminals c and d of the relay board via D. Then, the value of the determination counter Hc at the time of the falling of the game ball detection signal is stored, and based on the stored value, it is determined whether or not a special game state is caused, and a symbol is displayed on a display control device (symbol display). Send a signal to start the fluctuation. When the stored value is a specific value (for example, “7”),
After a predetermined time, the same symbol (special symbol) is fixedly displayed on the symbol display unit, and a special game state that is advantageous to the player is generated.

Next, matters relating to the prevention of fraudulent acts in the software stored in the ROM will be described.
It should be noted that the illegal act is the same software as the conventional one, in which the illegal substrate shown in FIG. (First Embodiment) The present embodiment will be described with reference to FIGS. 3A and 3B showing a control flow and FIG. 4 showing a pulse train. When the power is turned on, the judgment counter Hc,
The flag F and the special game state flag FA are initialized (S1, S2), and the initialized pulse signals are output to the terminals a, b of the display control device via the terminals A, B of the game control device. I do. Therefore, when an unauthorized board is attached, upon receiving this initialization signal, the cpu arranged on the unauthorized board initializes a pseudo counter Gc (0 to 329) that adds 1 by a pulse signal (see FIG. 4).

After the power is turned on, control is performed according to the control flow of FIG. 3B, and it is first determined whether or not the flag F is 1 (S5). This flag F outputs a pulse signal every predetermined time (2 ms) to the terminal A of the game control device,
It is to determine whether or not to output to the terminals a and b of the display control device via B, that is, whether or not to maintain the non-output state of the pulse signal. When the flag F is 1, Since the game ball has won the start winning opening, has passed the specific area, and has generated the "game ball detection signal", the process proceeds to step 10. On the other hand, when the flag F is not 1, since the pulse signal has not been output, step 6
It is determined whether or not a game ball detection signal has been generated.
Then, when the game ball detection signal is generated, the flag F is set to 1 in the subsequent processing so that a pulse signal every predetermined time (2 ms) can be output to the terminals a and b of the display control device. (S7). By this processing, the pulse signal for every predetermined time (2 ms) after the first game ball detection signal is generated is output to the terminal a of the display control device,
b can be output, and the pulse non-output state is released.

In step 8, it is determined whether or not the special game state is present, that is, whether or not the value of the determination counter Hc is a specific value ("7").
A is set to 1 (S9), and the process proceeds to step 10.
When the big hit flag FA becomes "1", the symbol display units L1 and L are displayed in another control flow (not shown).
2. After a predetermined period of time, the symbols of the variable display are sequentially stopped at L3, and after the same symbol (specific symbol) is fixedly displayed, for example, a special game state process such as opening the special winning opening 58 is performed.

In step 10, a pulse signal is output every predetermined time (2 ms) to the terminals a and b of the display control device via the terminals A and B of the game control device. Therefore, FIG.
Pseudo counter Gc
(0-329) thereafter receives a pulse signal and starts counting (see FIG. 4). Then, a process of adding 1 to the determination counter Hc is performed (S11). In the next step 12, it is determined whether or not the determination counter Hc is 329. When the determination counter Hc is 329, the determination counter Hc is initialized (Hc = 0) (S13), 0-3
The circulation number is 29.

As described above, the judgment counter Hc is 2 ms
The number of cycles is 1 for each cycle, and the pulse signal every 2 ms is generated after the game ball first wins the starting winning opening, that is, after the first "game ball detection signal" is generated (FIG. 4). , The count values of the pseudo counter Gc and the determination counter Hc are different. Since the time at which the "game ball detection signal" is first generated is completely arbitrary, it is almost impossible to make the value of the pseudo counter Gc equal to the value of the determination counter Hc.

As a result, the value of the pseudo counter Gc becomes
The value Hc (specific value) of the determination counter that causes the special game state cannot be specified. That is, when the value of the determination counter Hc is a specific value, a game ball detection signal cannot be output to the game control device, and the occurrence of an illegal special game state can be prevented. In the above description, the time at which the pseudo counter Gc can count is after the "game ball detection signal" is first generated (time T shown in FIG. 4), but is not limited to the first time, and the second time and the like are not limited to the first time. The reference may be used.

(Second Embodiment) In this embodiment, as shown in FIG. 5, the time at which the pseudo counter Gc can be counted is determined by setting the value of the judgment counter Hc to an arbitrary number (M).
It will be set later. Therefore, in step 6 of FIG. 3, it is determined whether or not the value of the determination counter Hc is "M" (S6 '), and if it is "M", the flag F is set to 1. The other steps are the same as those in the first embodiment (FIG. 3), and thus the description is omitted. With this setting, the value of the determination counter Hc and the value of the pseudo counter Gc are
Since the value is shifted by “M”, the output timing of the “game ball detection signal” to be in the special game state is not known, and it is possible to prevent the special game state from being generated arbitrarily.

The value of "M" may be changed each time a special game state occurs, or may be changed at any time as time elapses. As described above, if the value of “M” can be changed, it becomes more difficult to make the value of the pseudo counter Gc and the value of the determination counter Hc coincide. Further, in the first and second embodiments, when the power is turned on, the value of the determination counter Hc can be configured without initializing. By starting from any value, the value of the pseudo counter Gc can be further reduced. Judgment counter H
It is difficult to match the value of C.

(Third Embodiment) In this embodiment, the initial value of the judgment counter Hc is selected by using an initial value selecting means. As shown in FIGS. When the power is turned on, the judgment counter Hc is not initialized. Then, the initial value of the determination counter Hc is used as an initial value selecting means.
(A)) is set to, for example, the value of the lower 3 bits (S
11). When the power is turned on, this RAM (A)
The noise is set to a completely arbitrary value (0 to 7).
However, when the initial value of the determination counter Hc is 0, it is set to 1 because fraudulent acts cannot be prevented (S
12, S13). Then, thereafter, as in the conventional case, 2 ms
Each time, it outputs to the terminals a and b of the display control device via the terminals A and B of the game control device (S14).

According to the above control, the value of the judgment counter Hc and the value of the pseudo counter Gc are counted every 2 ms. However, these values differ only by the initial value of the RAM (A). Since the output timing of the "game ball detection signal" to be in the game state is not known, it is possible to prevent the special game state from being arbitrarily generated. Further, as another initial value selecting means, one or more memories (RAM (A)
(B), (C), etc.) are subjected to various processes such as addition, multiplication, division, logical product, logical sum, etc., and as a result, for example, the value of the lower 3 bits is set to the initial value of the determination counter Hc. There are methods, and any method may be set so that the initial value of the determination counter Hc is other than zero. Further, it may be configured not only at the time of turning on the power but also after a preset time has elapsed.

It is to be noted that each of the above embodiments may not be performed alone, but may be appropriately combined with each other.

[0027]

According to the gaming machine of the first aspect of the present invention, a pulse signal generated at predetermined time intervals is not sent to the display control device until a game ball detection signal is generated. Since the value is different from the value of the determination counter, the value Hc (specific value) of the determination counter that causes the special game state cannot be specified. That is, when the value of the determination counter Hc is a specific value, a game ball detection signal cannot be output to the game control device, and the occurrence of an illegal special game state can be prevented. Further, in the gaming machine according to the second aspect, the pulse signal non-output state is released by detecting the game ball by the game ball detector, so that the pulse signal is counted thereafter, which is different from the value of the determination counter. Therefore, fraudulent acts can be prevented. In the gaming machine according to the present invention, when the power is turned on, the initial value of the determination counter is selected through the initial value selecting means. Since the value is different from the value, the value Hc (specific value) of the determination counter that causes the special game state cannot be specified. That is, when the value of the determination counter Hc is a specific value, a game ball detection signal cannot be output to the game control device, and the occurrence of an illegal special game state can be prevented.
