Abstract

<P>PROBLEM TO BE SOLVED: To prevent the behavior of changing a set value in unauthorized manner. <P>SOLUTION: An opening signal is transmitted from a slot machine whose lower door is opened to a hall computer. In response to the opening signal, the opening pattern of the lower door is written in a memory in the hall computer. When the slot machine is shifted to a setting change mode, a mode-shifting signal is transmitted from the slot machine to the hall computer. When receiving the mode-shifting signal, the hall computer decides whether the actual opening pattern of the lower door coincides with an opening pattern coordinated with a machine number where selecting operation of the setting value is carried out. When the respective opening patterns match each other, a selecting operation permission signal is transmitted from the hall computer to the slot machine. In response to this, the selecting operation of the setting value is validated in the slot machine. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  A gaming machine having a door that opens and closes the inside of the gaming machine main body, and a selection operation for selecting one from a plurality of types of lottery tables with different winning probabilities is performed by opening the door, and each game The present invention relates to a gaming system including a gaming machine management device connected to each of the gaming machines so that the machines can be individually identified.

  In this specification, a pachislot machine is described as an example of one of the gaming machines, so that explanation is given using medals as gaming media, but the gaming media includes other media such as coins and pachinko balls. In addition, “inserting a medal (game medium)” includes inserting a bet with a bet button or the like in addition to actually inserting a medal into the medal slot. Furthermore, in the state where the symbols are aligned on the winning line, the state in which the winning combination is drawn in a lottery (hereinafter referred to as the winning combination lottery) to determine the winning combination in the state before winning, And

  Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and medals that are used as gaming media are given a certain value, and medals earned by playing games are various prizes. Can be replaced.

  The pachislot machine has, for example, a plurality of types of lottery tables with different winning probabilities of winning combinations. Depending on which lottery table is used to perform the winning combination lottery, the ratio of the number of medals paid out to the number of medals inserted, so-called A payout rate is determined. The payout rate is associated with a value called a set value on a one-to-one basis, and when changing the set value, the door for opening and closing the inside of the pachislot machine body is opened. By setting the set value for each pachislot machine, there is a merit that a business profit can be secured for the game arcade and that the game can be played fairly for the player. Furthermore, since there is a pleasure for a player to guess a pachislot machine having a setting value with a relatively high payout rate, the setting value is important in terms of excitement of gaming.

By the way, in recent years, a so-called goto act has been performed in which the setting value is illegally changed by a method different from the regular method, and this has resulted in a loss of profit. If a goto act is performed, the fairness of the game is lost, so that the game hall may suffer a loss of profit due to a decrease in players in addition to a direct loss of profit due to the goth act. For this reason, it is one of the important issues for each pachislot machine manufacturer to take countermeasures against the goto action. It has been proposed to disable this operation when the set value is changed. As a result, it is possible to prevent a goofing action of changing a set value by inserting a foreign object such as a wire from a hole opened in the door.
JP 2004-135443 A JP 2004-135844 A

  However, Goto acts are becoming more and more malicious every year, and their methods are diversifying. As one of the methods of goto action, for example, a method is known in which the door is unlocked using a foreign object such as a duplicated door key or wire, and the set value is changed by opening the unlocked door. If this method is used, it is impossible for the pachislot machine to determine whether the set value has been changed properly or whether the set value has been changed by the goto action. I had to find it. However, since goto acts are usually performed in a short period of time, it is difficult to detect goto acts from the player's behavior, and it is also difficult to perform goto acts on players who play games in a regular manner. It may be necessary to check whether or not this is done. This causes a player who plays a game in a regular manner to lose interest in the game, which is a cause of a decrease in the number of players who perform a game and a decrease in the profit of the game hall.

  An object of this invention is to provide the game system which can prevent the goto act which changes a setting value illegally.

  In order to achieve the above object, the gaming system of the present invention has a door for opening and closing the inside of the gaming machine main body, and the selection operation for selecting one from a plurality of types of lottery tables having different winning probabilities is described above. A plurality of gaming machines in which a game mode in which a game is played and a setting selection mode in which the selection operation is performed are set, and each gaming machine is identified so that each gaming machine can be individually identified. In a gaming system comprising a gaming machine management device connected to each of the gaming machines, each of the gaming machines transmits an opening signal indicating that the door is opened to the gaming machine management device, Transition signal transmitting means for transmitting to the gaming machine management device a mode transition signal indicating that the gaming mode has been switched to the setting selection mode, and the gaming machine management device includes the mode transition When the combination of the door opening determining means for determining whether or not the combination of the gaming machines whose doors are opened matches a preset combination, and the respective combinations match, And a permission signal transmitting means for transmitting a selection operation permission signal that enables the selection operation to be performed to the gaming machine that has transmitted the mode transition signal, and the selection operation is performed by the gaming machine that has received the selection operation permission signal. It is possible to perform.

  The opening signal transmitting unit continuously transmits the opening signal while the door is opened, and the transition signal transmitting unit transmits the mode while transitioning to the setting selection mode. If the release signal is interrupted before the mode transition signal is interrupted, the gaming machine management device transmits a setting invalid signal that invalidates the lottery table selected by the selection operation. It is preferable to provide invalid signal transmission means for transmitting to the game machine that is the transmission source of the mode transition signal.

  Moreover, it is preferable that the permission signal transmission means transmits the selection operation permission signal only within a preset period.

  The opening signal transmitting unit continuously transmits the opening signal while the door is opened, and the transition signal transmitting unit transmits the mode while transitioning to the setting selection mode. If the game machine management device receives the release signal from a gaming machine other than the gaming machine belonging to the preset combination during the reception of the mode transition signal, the selection operation is continued. The invalidation signal transmitting means for transmitting a setting invalidation signal for invalidating the lottery table selected by (1) to the gaming machine as the transmission source of the mode transition signal may be provided. Thereby, when the door of another gaming machine is opened during the selection operation, it can be confirmed whether or not the door is opened by the goto action, and it becomes easy to find a player who performs the goto action.

(Explanation of terms used in claims)
“Game machine main body” refers to a unit in which a device for executing a game (for example, a reel unit, a liquid crystal unit, a hopper device, etc.) or a substrate for controlling the drive of this device is stored in a storage box. .
Further, the “winning” is not limited to one type, and may be constituted by a plurality of types of hitting. When multiple types of winning are set, it is sufficient that at least any one winning probability differs between lottery tables.
Further, “invalid” indicates that even if a lottery table selection operation is performed, a process for responding to the selection operation is not performed. In order to invalidate the selection operation, for example, even if a selection operation is performed, the lottery table Appropriate measures can be taken, such as not selecting or not setting the lottery table selected by the selection operation.

  In the gaming system of the present invention, when the combination of gaming machines with the doors open matches a preset combination, a selection is made to select one from a plurality of types of lottery tables with different winning probabilities Since it becomes possible to perform the operation, it becomes impossible to change the set value without knowing the combination of the gaming machines that open the door, and it is possible to prevent the act of changing the set value illegally. In addition, since it is necessary to open the doors of a plurality of gaming machines in order to perform the selection operation, it is possible to increase the operation at the time of performing the selection operation, and it is easy to find a player who performs the goto action.

  In addition, when the door is closed during the setting selection mode, the lottery table selected by the selection operation for selecting one from a plurality of types of lottery tables having different winning probabilities is invalidated. It is possible to detect whether or not the work associated with is performed according to a regular procedure, and it is possible to prevent the act of changing the set value illegally. In addition, since it is necessary to open the door of the gaming machine while performing the selection operation, it becomes possible to easily identify the operation when performing the selection operation, and it is easy to find the player who performs the goto act Become.

  In addition, since the combination of gaming machines whose doors are opened only within a preset period is determined, it is possible to select from among a plurality of types of lottery tables that have different winning probabilities in the same manner as before during non-game hall business hours. A selection operation for selecting one can be performed, and this selection operation can be performed efficiently.

Then, the winning combination lottery result is displayed by the combination of symbols displayed from the display window 15.

  Below the display window 15 is provided a display device 17 for displaying numbers, specific alphabets, and the like. The slot machine 12 includes six types of lottery tables used in the winning combination lottery. The lottery tables have different winning probabilities for winning combinations. The ratio of the number of paid-out medals to the number of inserted medals, that is, the payout rate, changes depending on which lottery table is used to perform the winning combination lottery. The payout rate corresponds to each of the lottery tables, and can be changed in a range of 6 levels. Each payout rate is associated with a value called a set value. The set value is composed of six stages of settings 1-6. Settings 1 to 6 are associated with each payout rate so that the payout rate increases in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6. The display device 17 displays a setting value selected by the setting value selection operation and an error display when an error occurs.

  On the lower door 14b, the medal slot 18, the start lever 19 that is pressed when starting the rotation of the first to third reels 16a to 16c or confirming the selected set value, the rotating reel is stopped. First to third stop buttons 20a to 20c are provided.

  A cylinder 21 is provided on the front side of the lower door 14b. When a dedicated door key is inserted into the cylinder 21 and rotated, the locking of the lower door 14b is released.

  The setting key switch 41a is composed of a key cylinder. When performing a setting value selection operation, the setting selection key 42 is inserted into the setting key switch 41a after the lower door 14b is opened. Thereafter, when the setting selection key 42 is turned from the off position to the on position and the power switch 41b is turned on, the game mode in which a game is played shifts to a setting change mode in which a setting value selection operation is performed. When the setting change mode is entered, the operation of the setting selection button 41c is validated. When the operation of the setting selection button 41c is validated, the inserted medal is not accepted, and the operation of the start lever 19 and the stop buttons 20a to 20c is invalidated and it becomes impossible to play a game.

  When the setting selection button 41c is pressed during the setting change mode, the setting value is selected. When the setting selection button 41c is pressed, six stages of setting values are sequentially set in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6 → setting 1. It will be selected. When the start lever 19 is pressed after selection of the setting value with the setting selection button 41c is completed, the setting value selected with the setting selection button 41c is confirmed. When the setting selection key 42 is turned to the off position after the setting value is confirmed, the setting change mode is changed to the game mode, and the setting value selection is completed.

  As shown in FIG. 5, the gaming system 50 of the present invention includes a slot machine 12 and a hall computer 63. The operation of the slot machine 12 is basically controlled by the control board 60. The control board 60 includes a CPU 60a and a memory 61. The CPU 60 a includes a control unit 62, and the control unit 62 controls the operation of the slot machine 12 based on a program stored in the memory 61. In the ROM area of the memory 61, a game execution program for performing a process for executing a game, a setting selection execution program for performing a process for executing a process associated with a setting value selection operation, and various displays from the display device 17 are displayed. Data to be performed is stored, and when the control unit 62 reads out these programs, processing related to each operation is performed. The control unit 62 is connected to a hall computer (game machine management device) 63 that individually identifies each slot machine 12 in the game hall 10. The control units 62 of all the slot machines 12 are connected to the hall computer 63.

  In addition to the control unit 62, the CPU 60 a has a winning combination determination unit 64 that determines whether to lose or win each time a game is played, and an opening signal that transmits an opening signal indicating that the door has been opened to the hall computer 63. A transmission unit (open signal transmission unit) 65 and a transition signal transmission unit (transition signal transmission unit) 66 for transmitting a mode transition signal indicating that the game mode has been switched to the setting selection mode to the hall computer 63 are provided.

  The control unit 62 operates the winning combination determining unit 64 in response to the start lever 19 being pressed. The winning combination determination unit 64 includes a random number generator and a random number sampling circuit, and draws one random number every time a game is started.

  The winning combination determination unit 64 is provided with a lottery table 67. In the lottery table 67, all random numbers generated by the random number generator of the winning combination determining unit 64 are grouped into a plurality of numerical ranges, and a winning combination or a loss is assigned to each group. Then, the type of lost or winning combination is determined depending on which group the random number value selected by lot belongs to.

  The lottery table 67 is provided with six types of first to sixth setting tables 67a to 67f associated with six stages of setting values. In the first to sixth setting tables 67a to 67f, the numerical value ranges of the random number values to which the winning combinations are assigned so that the winning probabilities of the winning combinations are different from each other. For this reason, the payout rate of the slot machine 12 changes depending on which of the first to sixth setting tables 67a to 67f is compared with the random value sampled by the winning combination determining unit 64.

  Of the first to sixth setting tables 67a to 67f, the first setting table 67a has the lowest payout rate, and is selected so that the payout rates increase in the order of the second, third, fourth, fifth and sixth setting tables. The winning probability of the role is set. When setting 1 is selected, the first setting table 67a is selected. When setting value 2 is selected, the second setting table 67b is selected. When setting value 3 is selected, the third setting table 67c and the setting value 4 are selected. Sometimes the fourth setting table 67d, the fifth setting table 67e when the setting value 5 is selected, and the sixth setting table 67f when the setting value 6 is selected are used.

  The control unit 62 receives an operation signal from the setting key switch 41a, the power switch 41b, the setting selection button 41c, an ON signal of the lower door opening / closing switch 40, and the like. And the control part 62 performs the process accompanying selection operation of a setting value in response to each signal. The control unit 62 activates the opening signal transmission unit 65 in response to the ON signal of the lower door opening / closing switch 40. The opening signal transmission unit 65 transmits an opening signal to the hall computer 63. The opening signal is continuously transmitted while the lower door 14b is opened.

  Further, when both the ON signal of the power switch 41b and the ON signal of the setting key switch 41a are received, the control unit 62 shifts from the game mode to the setting change mode. When the mode is changed to the setting change mode, the control unit 62 operates the shift signal transmission unit 66. In response to this, the transition signal transmitter 66 transmits a mode transition signal to the hall computer 63. The mode transition signal is continuously transmitted while transitioning to the setting change mode.

  When the setting selection button 41c is operated and the operation signal is input, the control unit 62 causes the display device 17 to display the setting value selected by the setting selection button 41c. For example, the setting value is “−1−” when setting 1 is set, “−2” when setting 2 is set, and “−3−3” when setting 3 is set. “−4” when setting 4 is set, “−5−” when setting 5 is set, “−6−” when setting 6 is set, and so on. (Setting value)-"is displayed from the display device 17 in a mode. Each time the setting selection button 41c is pressed, the control unit 62 displays these indications as “−1−” → “−2” → “−3−3” → “−4” → “−5-” → Switch in the order of “−6” → “−1−” →. When the start lever 19 is pressed and the set value selected is confirmed, the control unit 62 displays the confirmed set value from the display device 17 in the form of “(set value)” (− is not displayed). Display.

  In response to the operation signal of the setting selection button 41c, the control unit 62 identifies the first to sixth setting tables 67a to 67f corresponding to the setting value selected by the setting selection button 41c. When the start lever 19 is pressed, the types of the selected first to sixth setting tables 67a to 67f are written in the RAM area of the memory 61, and the set value is confirmed. Thereby, the selection of the set value is completed. When a game is played, the control unit 62 refers to the RAM area of the memory 61 and identifies the type of setting table for collating the random value sampled by the winning combination determining unit 64. Then, the winning combination lottery is performed using the identified first to sixth setting tables 67a to 67f.

  The operation of the hall computer 63 is controlled by the control board 70. The control board 70 includes a CPU 71 and a memory 72. The CPU 71 includes a control unit 73, and the control unit 73 controls the operation of the hall computer 63 based on a program stored in the memory 72. The control unit 73 receives various signals from the slot machine 12 and performs processing according to the type of the received signal.

  The control unit 73 is connected to a door opening determination unit (door opening determination unit) 74, a permission signal transmission unit (permission signal transmission unit) 75, and an invalid signal transmission unit (invalid signal transmission unit) 76.

  When receiving the opening signal from the slot machine 12, the control unit 73 writes the combination of the serial numbers of the slot machine 12 with the lower door 14 b opened (hereinafter referred to as “opening pattern”) in the RAM area of the memory 72. deep. In the ROM area of the memory 72, a combination of slot machines 12 (hereinafter referred to as “opening pattern”) that opens the lower door 14b is written in advance so that a setting value can be selected. The opening pattern of the lower door 14b written in the ROM area of the memory 72 is individually set so as to correspond to each of the slot machines 12 installed in the game hall 10 (for example, the selection operation is performed with the machine number A). In this case, when the lower door 14b is opened in the slot machine 12 having the table number A and the table numbers F, G, and H, the selection operation can be performed using the table number A. If the lower door 14b is opened in the slot machines 12 with the numbers A, B, C, the selection operation can be performed with the base number F). When the control unit 73 receives the mode transition signal from the slot machine 12, the control unit 73 reads the opening pattern of the lower door 14 b that is actually opened from the RAM area of the memory 72 and inputs the read pattern to the door opening determination unit 74. The opening pattern that can be selected by the slot machine 12 that is the transmission source of the opening signal is read from the ROM area of the memory 72 and input to the door opening determination unit 74. Then, the door opening determination unit 74 determines whether or not the respective opening patterns match.

  The permission signal transmission unit 75 is activated when the door opening determination unit 74 matches each opening pattern. In response to this, the permission signal transmission unit 75 transmits a selection operation permission signal that enables the slot machine 12 that is the transmission source of the mode transition signal to perform a setting value selection operation to the control unit 62 of the slot machine 12. .

  The invalid signal transmission unit 76 is activated when the open signal is interrupted before the mode transition signal is interrupted. In response to this, the invalid signal transmitting unit 76 transmits a setting invalid signal that causes the slot machine 12 that is transmitting the mode transition signal to invalidate the setting value selected by the selection operation, to the control unit 62 of the slot machine 12. .

  Further, the hall computer 63 is provided with a registration operation unit 77 for registering a period during which a determination function for performing the determination by the door opening determination unit 74, that is, a period for transmitting the permission signal to the slot machine 12 by the permission signal transmission unit 75 is registered. It has been. The registration operation unit 77 registers the period by inputting the time. An operation signal from the registration operation unit 77 is input to the control unit 73. The control unit 73 writes the time input by the registration operation unit 77 in the RAM area of the memory 72. A clock 78 is connected to the control unit 73, and the control unit 73 identifies whether it is during the registered period by monitoring the time of the clock 78 and the time written in the memory 72.

  Next, a setting value selection operation flow and a process flow associated therewith in the slot machine 12 having the machine number A configured as described above will be described. As shown in FIG. 6, first, a period during which the hall computer 63 executes the determination function is registered by operating the registration operation unit 77.

  Thereafter, the operator who performs the selection operation opens the lower door 14b with the slot machines 12 having the table numbers A and F to H.

  From the slot machine 12 having opened the lower door 14b, transmission of an opening signal to the hall computer 63 is started. In response to the opening signal, the hall computer 63 writes the opening pattern of the lower door 14 b in the memory 72.

  Thereafter, in the slot machine 12 of the machine number A, when the setting selection key 42 is inserted into the setting key switch 41a, the setting selection key 42 is turned to the on position, and the power switch 41b is turned on, the control unit 62 reads the setting selection execution program from the memory 61 and shifts to the setting change mode.

  At this time, transmission of a mode transition signal from the slot machine 12 to the hall computer 63 is started. When the mode transition signal is received, the hall computer 63 determines whether or not the actual opening pattern of the lower door 14b matches the preset opening patterns (the table number A and the table numbers F to H).

  When the respective opening patterns match, a selection operation permission signal is transmitted from the hall computer 63 to the slot machine 12. In response to this, the slot machine 12 accepts an operation signal when the setting selection button 41c is pressed. Thereby, the operation of the setting selection button 41c is validated.

  If the combinations do not match, the selection operation permission signal is not transmitted, and the operation of the setting selection button 41c remains invalidated.

  When the setting selection button 41c is pressed after the operation of the setting selection button 41c is validated, the control unit 62 identifies the first to sixth setting tables 67a to 67f corresponding to the setting value selected at this time. . When the start lever 19 is depressed after selection of the setting value is completed, the control unit 62 writes the first to sixth setting tables 67a to 67f corresponding to the selected setting value in the RAM area of the memory 61. Thereby, the selected set value is confirmed. When the setting selection key 42 is turned to the off position, the setting change mode ends.

  Here, when the lower door 14b is closed by any of the slot machines 12 of the platform numbers F to H before the setting selection key 42 is turned to the OFF position, that is, before the mode transition signal is interrupted, the opening signal is interrupted. In this case, a setting invalid signal is transmitted from the hall computer 63 to the slot machine 12. When the setting invalid signal is received, the control unit 62 clears the lottery table written in the memory 61. As a result, the set value cannot be determined and the game cannot be performed. At this time, it is preferable to perform error notification at the same time.

  After finishing the setting change mode, all the opened lower doors 14b are closed. When it is detected that the lower door 14b is closed, the transmission of the opening signal from the slot machine 12 to the hall computer 63 is interrupted. And the control part 62 reads the game execution program from the memory 61, and makes it the state which can play a game. In the present embodiment, when the lower door 14b is opened by the slot machine 12 having the table numbers G to H across the partition wall 11a, the selection operation can be performed using the table number A. When performing an action, the lower door 14b of the slot machine 12 across the partition wall 11a must be opened, thereby increasing the action of the player who performs the goto action and discovering the player who performs the goto action. It becomes easy.

  In the above-described embodiment, the selection operation can be performed by opening the lower door 14b so as to match the preset opening pattern. However, for example, the opening pattern is set in units of islands. May be set appropriately.

  In the embodiment described above, the selection operation can be performed by the slot machine 12 with the table number A with respect to the release patterns with the table numbers F, G, and H. For example, the release patterns with the table numbers A, B, F, G, and H are available. Thus, the selection operation may be performed by a plurality of slot machines 12 by one release pattern, for example, the selection operation can be performed by the two machine numbers A and B.

  In the above embodiment, the present invention is applied to the slot machine 12 that drives the reel. However, the present invention is applied to a gaming system constituted by other gaming machines such as a slot machine or a pachinko machine that displays a variation of symbols by a liquid crystal panel, for example.
