Description

The present invention relates to a control device for a gaming machine that performs a game control that gives a predetermined game value such as a hit or jackpot in a gaming machine such as a pachinko gaming machine or a slot gaming machine. The present invention relates to a control device for a gaming machine characterized by setting conditions for starting game control for giving a predetermined game value.

For example, a pachinko gaming machine is configured by forming a gaming area having a plurality of winning tools on the front surface of the gaming board, and a predetermined number of game balls that are launched into the gaming area and move to fall into the winning equipment. It is a play equipment configured to pay out award balls (for example, 5, 10, or 13). As such a winning tool, only a predetermined number of award balls are paid out to one winning ball, a so-called tulip is opened in response to the winning, or the next winning is facilitated. There are those that open a so-called big winning opening under gaming conditions and establish a special gaming state to enable a large number of winning balls to be obtained.

In the special gaming state, the symbols are variably displayed on the liquid crystal display device (symbol display device) provided in the center of the game board constituting the game area in accordance with the winning of a predetermined prize device provided in the game area. The game state is established according to the type of the stop symbol when the variable symbol is stopped. For example, in the symbol display device, a number or the like is rotated and displayed as in the three rotating drums of the slot machine, and the special gaming state ( The jackpot gaming state is established. When the special gaming state is established in this way, the big winning opening provided at the lower part of the gaming area is opened to facilitate the winning of the game ball so that the player can acquire a large number of game balls. It has become.

In order to determine such a stop symbol, a control arithmetic unit (CPU), a memory (RAM, RO
M), a game control device configured with a random number counter or the like is provided in the pachinko gaming machine. In this game control device, for example, the random number counter generates a random number that increases by 1 from 0 to a predetermined number at a predetermined cycle, and this random number is updated and stored in the RAM, and a game ball wins a special game prize device. The special gaming state is established when the random number updated and stored in the RAM sometimes matches a preset value. In other words, whether or not the special game state is established by displaying a stop symbol that matches the numbers when the three rotating drums are stopped as described above is a disturbance when the game ball is won in the special game winning tool. It is determined based on whether or not the numerical value matches a preset value, and when they match, the display for matching the stop symbols of the three rotating drums is performed as described above, and the special gaming state is displayed. Control to establish is performed.

The random number counter is incremented by 1 from 0 to a predetermined number and is 0 when the predetermined number is reached.
Since the random number is generated with a predetermined regularity, such as a random number that increases by 1 again, the special gaming state is determined if the special gaming state is established and the random number generation cycle is known. It is possible to perform illegal control such that a special game state is arbitrarily generated by giving a winning signal of a game ball to be established to a control arithmetic unit from the outside. For example, if the acquisition timing of random numbers is constantly monitored and the time when the game ball wins a predetermined prize and the special game state is established is detected, the special game state is changed according to the random number generation cycle thereafter. By outputting a pseudo winning signal to the control arithmetic unit at the timing of generation, it is possible to perform illegal control that arbitrarily establishes a special gaming state.

Recently, a fraudulent board called a “hanging board” that exploits this principle has been attached to the backside of a gaming machine, etc., and a pseudo winning signal is given to the control arithmetic unit by this hanging board to generate a special gaming state. There was a problem of winning a lot of winning balls. Therefore, as a countermeasure against such a fraud, it has been proposed to generate random numbers irregularly (for example, JP-A-2001-29580).

However, even when the random number is generated irregularly as described above, when the control device itself is reset, the random value stored in the storage means (RAM or the like) is reset to the initial value (0), and the random number is counted again from the initial value. Since the initial value after reset is always the same, after the reset signal is output by the hanging board, a pseudo winning signal is sent at a predetermined timing, and a special game state is arbitrarily generated. Injustice occurred.

As one countermeasure against such injustice, Japanese Patent Laid-Open No. 11-70254 provides an EEPROM capable of storing a counter value even when the gaming machine is turned off, and when the gaming machine is turned on. The RAM is initialized (for example, the process of returning the counter value to the initial value), and the value stored in the EEPROM is set as the initial value of the counter value, and the random number counter by the random number counter is set from the initial value thus set. It has been proposed to let the settings be made. Japanese Patent Laid-Open No. 11-70256 discloses means for continuing counting even after the power is turned off (RT
C: Real Time Counter), the RAM is initialized when the power is turned on, and a random number counted after the power is turned off by the RTC is set as the initial value of the counter value. It has been proposed to set a random number using a random number counter from an initial value.

According to such a proposal, even if the reset signal is output from the hanging board and the RAM value is reset, the initial value of the counter value set in the RAM is the EEPROM as described above.
Alternatively, since it is replaced with a random number set by the RTC, the hanging board cannot set a random value in accordance with this, and it is possible to prevent the special gaming state from being set illegally. However, in this case, the configuration of the control board itself is required, such as an EEPROM that stores and holds the previous random number value even after the power is turned off, and an RTC (Real Time Counter) that continues the random number count even after the power is turned off. Need to change. For this reason, there is a problem that the cost of the control board is increased, and further, when the EEPROM is used, the EEPROM
There is a risk that the ROM itself may be replaced and fraudulent, and the rewriting speed of the random number counter value may be slow, which may put pressure on the game control processing time, and if RTC is used, the backup power supply needs to be strengthened. There is.

The present invention has been made in view of such problems, and provides a control device for a gaming machine that can cope with fraud using a so-called “hanging board” or the like by control software without changing the configuration of the control board. For the purpose.

In order to achieve such an object, the control device for a gaming machine according to the present invention has rewritable storage means for storing a random number counter value and the random number counter value stored in the storage means has a predetermined regularity. Random number counter updating means for updating based on the result of the calculation, and a random number stored in the storage means is read at a predetermined timing to obtain a lottery value, and predetermined when the read lottery value matches a preset value. And an arithmetic controller for performing game control to give the game value, and further comprising initial value setting means for setting a random number counter value stored in the storage means to an initial value in response to a reset signal ing. The random number counter updating means is provided in the calculation controller, and updates the random number counter value stored in the storage means at predetermined time intervals based on the result of the calculation having a predetermined regularity by the calculation controller. The initial value setting means is provided in the arithmetic controller, and when the reset signal is received by the interrupt processing for reset by the arithmetic controller, the random number counter value stored in the storage means is received by the arithmetic controller. The storage means is initialized after being stored in the internal register (that is, always set to a constant value, for example, zero), and then the random number counter value stored in the register is initialized to the initial value of the random number counter value stored in the storage means Is configured to set as

Further, when the random number counter value stored in the storage means is received in the register in the arithmetic controller upon receiving the reset signal, or when the random number counter value stored in the register is reset as the initial value of the storage means A random number counter value stored in the storage means for determining whether or not the random number counter value is within the normal range, and a random number when the comparison means determines that the random number counter value is not within the normal range value. Random number correction means for subtracting the counter value and correcting it to a value within the normal range, so that the random number counter value corrected and set by the random number correction means is stored in the register or reset as the initial value of the storage means It is configured.

In the gaming machine control device having the above-described configuration, the random number counter updating unit updates the random number counter value based on the calculation result having a predetermined regularity. It is preferable to provide random number update processing irregularizing means for irregularly changing the random number counter value to be updated.

Also, when receiving the reset signal, the arithmetic controller performs an operation using the random number counter value and other numerical data stored in the storage means, and uses the operation result value as the random number counter value. Preferably, the storage means is initialized after being stored in the internal register, and then the random number counter value stored in the register is reset as the initial value of the storage means.

According to the present invention, when receiving the reset signal, the arithmetic controller initializes the storage means after storing the random number counter value stored in the storage means in the register in the arithmetic controller, Since the random number counter value stored in is set as the initial value of the storage means, even if the “hanging board” is improperly attached and the control device is reset by the reset signal from the hanging board, the calculation is performed. The controller stores the random number counter value immediately before reset (the value updated and stored in the storage means) in the register, and then initializes the storage means (for example, RAM), and stores the register in the storage means thus initialized. Since the stored random number counter value is set as an initial value, the initial value of the random number counter value after reset is random. For this reason, even if a hanging board is used, it becomes impossible to grasp the timing at which the special gaming state is generated, and it is possible to reliably prevent fraud by the hanging board.

Further, when the random number counter value stored in the storage means is received in the register in the arithmetic controller upon receiving the reset signal, or when the random number counter value stored in the register is reset as the initial value of the storage means A comparing means for determining whether or not the random number counter value stored in the storage means is a value within the normal range, and when the comparing means determines that the random number counter value is not within the normal range And a random number correcting means for subtracting the random number counter value to correct the value within the normal range, and storing the random number counter value corrected and set by the random number correcting means in the register or as an initial value of the storing means. It is preferable to configure. As a result, even when the value stored in the storage means is an abnormal value during power off, the random number counter value is corrected to a normal range value at power on or reset, Subsequent control can be normally performed.

Furthermore, in the gaming machine control device having the above-described configuration, the random number counter updating means updates the random number counter value based on the calculation result having a predetermined regularity. It is preferable to provide random number update processing irregularizing means for irregularly changing the random number counter value to be updated. As a result, the random number counter value that is updated and stored becomes irregular, and fraud using a hanging board or the like can be prevented more reliably.

For the same reason, when receiving the reset signal, the operation controller performs an operation using the random number counter value and other numerical data stored in the storage means, and uses the value of the operation result as the random number counter value. Preferably, the storage means is initialized after being stored in the register in the arithmetic controller, and then the random number counter value stored in the register is reset as the initial value of the storage means. As a result, it becomes very difficult to predict the initial value stored in the storage means after resetting, and illegal use using the hanging board can be reliably prevented.

In a game using the pachinko machine PM, a game ball is thrown into the upper ball tray 7a and the firing handle of the hitting ball launching device 8 is operated by hand to inject the game balls into the game area 11 one by one. In response to this, the game ball moves randomly in the game area space sandwiched between the front surface of the game area 11 and the inner surface of the glass plate 5a by being repelled or guided by the game nails or the windmills 14a to 14d. Move downward while changing direction.

At the time of the fall movement, the game ball is one of the general prizes 16a, 16b, 34a, 34.
When winning in b, the winning is detected by the winning detection sensors 16c, 16d, 34c, 34d, and the detection signal is sent to the control unit 60. When this detection signal is received, an operation signal is output from the control unit 60 to the ball payout device 45, and the ball payout device 45 is operated to raise a predetermined number (for example, 10 balls) of the winning balls to each winning ball. Dispensing to the lower bowls 7a, 7b.

On the other hand, when a game ball falling and moving in the game area space passes through the left passage gate 15 a, this is detected by the passage sensor 15 c and a detection signal is sent to the control unit 60. The control unit 60 performs tulip opening control S10 shown in the flow of FIG. 12 based on this passage detection signal. In this control, the passage sensor 15c detects that the game ball has passed the left passage gate 15a, and the detection signal is input (step S).
11), the process proceeds to step S12, and in the display of the auxiliary fluctuation indicator 32 that displays while changing the one-digit number, the number to be a stop symbol is determined from the one-digit number by random lottery,
The auxiliary variation indicator 32 is activated (step S13). In this random number lottery, when the passage sensor 15c detects that the game ball has passed through the left passage gate 15a, the random number counter unit 6 of the RAM 63 that stores and updates the random number counter value for the tulip release lottery.
The random number counter value stored from 3a is read as a lottery value, and it is determined based on whether the lottery value matches a predetermined number (for example, 7) that is a preset hit. As a result, the auxiliary fluctuation indicator 32 displays a single digit number while fluctuating, and the stop symbol determined in step S12 is displayed on the auxiliary fluctuation indicator 32 after a predetermined time (step S14).

Then, it is determined whether or not the stop symbol determined in this way is a predetermined number (for example, 7) to win (step S15), and when the stop symbol is a predetermined number (for example, 7), a step is performed. Proceeding to S16, blade opening / closing solenoid mechanism 1 for a predetermined time (for example, 0.5 seconds)
7d is operated to open the tulip blades 17a and 17b. When the number of stop symbols is other than the predetermined number, the tulip opening control is not performed and the flow is finished as it is.

While the tulip opening control S10 is being performed as described above, another game ball may pass through the left passing gate 15a. At this time, when a passage detection signal is input from the passage sensor 15 c to the control unit 60, the control unit 60 stores this in a tulip opening control frequency memory constituted by one of the RAMs 63 and an auxiliary consisting of four LEDs. One of the symbol variation storage display unit 33 is turned on. Then, when the tulip opening control S10 is completed, the tulip opening control S10 corresponding to the storage in the tulip opening control frequency memory is performed. However, along with the start of this control, the memory of the tulip opening control count memory is erased and the lighting display of the auxiliary symbol variation display unit 33 is turned off. Such storage in the tulip opening control count memory and lighting display on the auxiliary symbol variation display section 33 can simultaneously detect up to four passages, and the fifth passage is ignored. That is, during the tulip release control S10, until the four game balls pass through the left passing gate 15a, it is stored and held, but even if more game balls pass, it is stored in the control. Ignored. For this reason, the auxiliary symbol variation storage display unit 33 is composed of four LED displays.

In this way, when the game ball wins the starting prize device 17 with the tulip blades 17a and 17b opened or with the tulip blades 17a and 17b closed, the special game control means 65 Special game setting control S20 shown in FIG. 13 is performed. Note that the above-described game until the special game setting control is performed is referred to as a normal game.
In this control, when a winning of a game ball to the start winning device 17 is detected by the winning detector 17c (step S21), first, a random lottery for determining whether or not a special gaming state is generated for this winning is performed. Along with (Step S22), the prize ball payout control means 64 performs control to pay out a predetermined number (for example, 5) of prize balls to the upper or lower ball trays 7a and 7b (Step S2).
3). This random number lottery is stored from the random number counter unit 63a of the RAM 63 that updates and stores the random number counter value for the special game start lottery when the winning of the game ball to the start winning tool 17 is detected by the winning detector 17c. The random number counter value is read as a lottery value, and the lottery value is determined based on whether or not the lottery value matches a predetermined number that is set in advance.

At the same time, the liquid crystal display 22 in the display device 20 disposed on the game board 10 is operated to control the special symbols to be displayed in a variable manner on the screen of the liquid crystal display 22 (step S24).
This is displayed on the liquid crystal display screen so that special symbols such as numbers, letters, pictures, etc. provided on each rotating drum change according to the rotation of the drum as if the three rotating drums of the slot machine rotate. To do.

After such special symbol variation display is performed for a predetermined time, a predetermined stop symbol is displayed on the liquid crystal display 22 in accordance with the lottery result in step S22 (step S25). In the process of displaying the stop symbol, various animation patterns and various effect patterns are displayed that are a display that attracts and enjoys the player's interest, which is called “reach”. This effect pattern is, for example, when two symbols out of three symbols are stopped and displayed, and when these two stop symbols match, the remaining symbols are stopped and displayed until the three stopped symbols are confirmed. Are various performance patterns that are performed in the game, which gives the player expectations for the stop symbol,
I try to improve the game. This effect pattern is set and stored in advance in the effect pattern memory in the ROM 62 and is read out based on the random number lottery result in step S22, but the description thereof is omitted.

Here, when the lottery result in step S22 is a win, in step S25, a winning symbol (for example, a symbol having the same number corresponding to three drums) is stopped and displayed on the liquid crystal display 22, and from step S26 to step S27. Proceed to On the other hand, when the lottery result is out, in step S25, the out-of-line design (for example, the design with different numbers corresponding to the three drums) is stopped and displayed on the liquid crystal display 22, and the control is terminated from step S26. When the lottery result in step S22 is out, such a display is made, and the special gaming state is returned to the normal gaming state.

By the way, the lottery result in step S22 is a win, and step S26 to step S
When the process proceeds to 27, it is determined whether the winning symbol displayed based on the lottery result in step S22 is a specific symbol or a non-specific symbol. If the symbol is a specific symbol, step S30 is performed.
The first special game control is performed, and when the symbol is a non-specific symbol, the second special game control in step S40 is performed. The specific symbol is, for example, a symbol in which three symbols that are stop symbols coincide with predetermined characters, pictures, or 7 numbers, and the non-specific symbol is, for example, that the three symbols that are stop symbols are other than 7. It is a design that matches with numbers.

Therefore, the first special game control in step S30 will be described with reference to FIG. The first special game control is a control for establishing a special game state in which a unit game can be executed a predetermined number of times (for example, 14 times). First, a unit game end condition for ending a unit game is selected (step S1). S31). The unit game ending condition is that the opening / closing door 35 is opened and the big prize opening 31a.
To the first and second winning openings 37a, 37b and the number of winning balls and a specific area, that is, the first
The unit game end condition is set in advance according to the condition whether or not to end the unit game by winning the winning opening 37a and the time limit. In step S31, the unit game end condition is read out.

When the unit game end condition is selected in this way, the process proceeds to step S32, where the door opening solenoid mechanism 36 is operated to open the opening / closing door 35 of the attacker device 30 to start the first unit game. When the opening / closing door 35 is opened, the state shown in FIGS.
5 is tilted forward by about 90 degrees, and the game ball falling and moving in the game area space is received by the opening / closing door 35 and is very easy to win from the large winning opening 31a into the first and second winning openings 37a and 37b. Become. When a game ball wins in the first or second winning opening 37a, 37b in such a state, a predetermined number (eg, 13) of winning balls are given to the winning ball by the winning ball payout control means 64. It is paid out to the upper or lower ball tray 7a, 7b.

At this time, when the specific area guide plate 38 is swung to the specific area guide position, it is easy to win the specific area, that is, the first winning port 37a, and when the specific area guide plate 38 is swung to the non-specific area guide position, It becomes easy to win a specific area, that is, the second winning opening 37b. Here, when the opening / closing door 35 is opened by the guide plate driving mechanism 38a, the guide plate driving mechanism 38a is swingably moved to the specific area guide position and is set so as to be easily awarded to the first winning opening 37a, and the gaming ball is placed in the first winning opening 37a. From the time when the prize is won, it is swung to the non-specific area guiding position.

When the first unit game is started in this manner, step S31 is performed as described above.
It is determined whether or not the unit game end condition selected in step S3 is achieved (step S33), and the operation of step S32 is continued until the unit game end condition is achieved.

When it is determined in step S33 that the unit game is performed under the operation of step S32 as described above and the unit game end condition selected in step S31 is achieved, step S33 is performed.
After closing the open / close door 35 in 34, it is determined in step S35 whether the continuation condition is achieved. This continuation condition is a condition that whether or not a game ball has won in a specific area, that is, the first winning port 37a during a unit game, and the continuation condition is only given when there is a win in the specific area during the unit game. Judged to be achieved. For this reason, when the unit game is terminated without winning the specific area, the process proceeds from step S35 to step S37, and control for terminating the current special game is performed as it is.

On the other hand, when it is determined in step S34 that the continuation condition is satisfied (when there is at least one winning ball in the specific area during the current unit game), the process proceeds to step S36. Then, the process returns to step S32 until the unit game repeat count (round number) after starting the current first special game state is 14, and the next unit game is performed. When the unit game is repeated 14 times in this way, the process proceeds from step S36 to step S37, and the current first special game state is terminated.

In the second special game control in step S40, almost the same control as that of the first special game is performed.
Therefore, although the explanation is omitted, the first special game control and the second special game control are different in the unit game end condition, the continuation condition, and the number of times the unit game is performed, and the first special game is more Conditions that make it easier to win more prize balls than two special games are set.

Next, reset processing based on the reset signal from the reset circuit 68 shown in FIG. 11 will be described with reference to FIG. As described above, the reset process is performed by the pachinko machine P.
The reset circuit 68 outputs a reset signal when the M power switch is turned on to start supplying power from the power circuit 66 (when the power is turned on). More specifically, when a reset signal from the reset circuit 68 is input to the control unit 60, the CPU
The reset processing shown in FIG. Therefore, when a reset signal other than the reset signal from the reset circuit 68 at power-on is input to the control unit 60, for example, when a reset signal from an unauthorized board such as a hanging board is input to the control unit 60. In addition, the reset process shown in FIG. 11 is performed.

When performing this reset process, first, the current random number counter value updated and stored in the random number counter unit 63a of the RAM 63 is saved and stored in the register 61a of the CPU 61 (step S51), and then the process of initializing the RAM 63 and the like is performed. Is performed (step S52). Next, the random number counter value saved in the register 61a is a value within a predetermined range (for example, 0
˜630), and if it is a value outside this range, a process of correcting it to a value within the range is performed (step S53). For example, this correction process is performed when the random number counter value is 90.
When 0, a value 2 obtained by subtracting the upper limit value (630) of the range of the random number counter value from this
In this process, 70 (= 900−630) is used as the corrected random number counter value. This random number correction process may be performed before the random number counter value is saved in the register 61a in step S51. The value thus corrected is updated and stored in the random number counter unit 63a of the RAM 63, and this value is reset as the initial value of the random number counter unit 63a (step S5).
4).

As a result, the random number counter unit 63a after the reset process does not have the initial value (for example, 0) set by the normal initialization process, but the value updated and stored in the random number counter unit 63a immediately before the reset becomes the initial value. The initial value after reset cannot be predicted. For this reason, even if the hanging board as described above is connected to the control unit 60 and the reset signal is output from the hanging board to set the random number counter value of the random number counter unit 63a to the initial value, this initial value cannot be predicted. Thus, unauthorized operation using the hanging board can be prevented.

After the above reset process is performed, the random number counter value stored in the random number counter unit 63a is increased at predetermined time intervals by an interrupt process by the CPU 61, and the increased value is increased in the random number counter unit 63a. Is controlled to be updated and stored as a random number counter value (step S55). In the apparatus of this example, the randomization process is performed so that the random number counter value updated and stored in the random number counter unit 63a changes with irregularity (step S56). As the irregularization processing, for example, a plurality of random number counter units 63a are provided by using a plurality of storage areas of the RAM 63, and the random number counter units 63 are provided.
a random number counter value having different regularity in a is generated and updated and stored, and a value obtained as a result of arithmetic processing of the plurality of counter values is updated and stored in a random number counter unit 63a in a predetermined storage area in the RAM 63; There is a method of using this as a random number counter value for determining the lottery value in the random number lottery described above.

In the above reset processing, the random number counter value updated and stored in the random number counter unit 63a of the RAM 63 is saved and stored in the register 61a of the CPU 61 as it is.
A predetermined calculation is performed using the other numerical data stored in the AM 63 and the random number counter value stored in the random number counter unit 63, and the numerical value obtained as a result of the calculation is stored in the register 61a of the CPU 61 as a random number counter value. It may be saved. As a result, it becomes more difficult to predict the initial value to be reset in the random number counter unit 63a after the reset process, and fraud prevention can be performed more reliably. For the same purpose, a plurality of random number counter units 63a are provided by using a plurality of storage areas of the RAM 63, and predetermined calculations are performed using the random number counter values updated and stored in the plurality of random number counter units 63a. The calculation result is stored in the register 6
You may make it make it save and memorize | store in 1a. The predetermined calculation includes various calculations such as adding / subtracting / multiplying / dividing a plurality of numerical values.

In the control unit 60 described above, the memory of the random number counter unit 63a is stored by the backup power supply 64 even after the power supply from the power supply circuit 66 is cut off. good. In this case, when the reset process by the reset signal from the reset circuit 68 is performed when the power supply from the power circuit 66 is started, the memory of the random number counter unit 63a of the RAM 63 is erased, but the game is once started. Thereafter, the random number counter value is updated and stored in the random number counter unit 63a unless the power is turned off. For this reason, even if the hanging board is improperly attached and a reset signal is issued from here during the game, the initial value of the random number counter unit 63a cannot be predicted as described above, and illegal game control is ensured. Can be prevented.
