Description

  The present invention relates to a gaming machine capable of executing control while storing information related to game progress and effects in a storage device and retaining the stored information even after power supply is stopped.

  Conventionally, in gaming machines, when a power supply stoppage (power failure) is predicted, a technique for interrupting the processing up to that point and performing power failure processing and backing up information necessary for control to a storage device such as a RAM is known. (For example, refer to Patent Document 1). This known technology relates to a pachinko machine that includes a frame (game machine main body) and a game board that is attached to and detached from the frame, and that pays out a predetermined number of game balls when a game ball wins a winning area of the game board. It is. In particular, in the publicly known technology, when performing backup control in the event of a power failure, the accessory control device performs memory retention of the gaming state, while the discharge control device performs detection of winning balls over a predetermined time from the occurrence of the power failure. Yes. For this reason, in the publicly known technology, when the power failure occurs, the accessory control device backs up the gaming state and finishes the operation first (waiting for the power failure), but the accessory control device delays a predetermined time (about 5 seconds) and wins a prize. The operation ends after backing up the detection result of the sphere.

  In this way, in the known technology, two control devices prepare for a power failure separately with a time difference from each other, so that the game state at the time of the power failure (a special game state advantageous to the player or a normal game state) It is possible to back up the profit that the player should have been able to receive as a prize ball by winning. Therefore, after the power supply is resumed and the power is restored from the power failure, the game can be resumed from the middle of the big hit game, and if there is a winning ball before the power failure, the payout of the corresponding winning ball must be surely made. Can do.

Japanese Patent No. 3142790 (page 1-2)

  The known technology described above detects the winning ball within a certain delay time by defining the order in which the two control devices (object control device, discharge control device) end (shut down) when a power failure occurs. This is characterized in that the player is surely completed, thereby preventing a player's disadvantage. In this way, in gaming machines, it is also important to execute backup control from the viewpoint of securing the player's legitimate interest from the time of power failure to the time of power recovery, but in recent years it has responded to increasingly sophisticated fraud. This is also emphasized.

  That is, in a gaming machine having a concept of “setting (stepwise setting values of 1 to 6)” that determines the degree of profit received by a player like a slot machine, the setting is changed by an illegal act, and as a result However, there is a damage that a large amount of balls are acquired against the intention of the game hall operator. Such a fraudulent act is executed by illegally rewriting the setting value information stored in the inside of the slot machine (control board) by playing a power outage and playing the game as it is, Since there is no damage or deformation of the slot machine on the surface, it is not easy to find it from the outside. Although the above-mentioned known technology is excellent in that it can secure the player's profit at the time of power recovery by backup control at the time of power failure, it lacks the viewpoint of preventing fraudulent acts that abuse the power failure, and becomes more sophisticated There is no way to counter fraud.

  Therefore, the present invention provides a technology that can counter fraudulent acts that abuse power outages.

(Solution 1)
When the game machine of the present invention receives a start operation by a player with a predetermined number of game values for each game, the game machine rotates a plurality of movable display bodies having a symbol row formed on the surface in one direction. The display of the symbols is changed, and after that, when a plurality of stop operations are sequentially received by the player, the rotation of the movable display bodies is stopped one by one in the order in which the stop operations are received, and all the movable display bodies are In a gaming machine that determines the result of a game based on the display mode of a symbol when the rotation of the game stops, an internal lottery means for performing a predetermined internal lottery for each game and determining a winning result, As a lottery winning result, a small role defining means for prescribing a small role with game value addition, and as a winning result of the internal lottery, a special winning type defining means for defining a special winning type different from the small role, If a symbol corresponding to the small role is displayed in a prescribed manner when all of the movable display bodies are stopped in a game played in a general normal gaming state, the number of game values corresponding to the small role is displayed to the player. Even if the game value granting means to be given to the player and the game corresponding to the normal game state are displayed in a prescribed manner when the symbols corresponding to the special winning type are displayed when all the movable display bodies are stopped, Game ending means for ending the current game without giving value, and symbols corresponding to the special winning types are displayed in a prescribed manner when all the movable display bodies are stopped in the game played in the normal gaming state. When the current game is finished without giving a game value by the game ending means, the special game state transition means for making a transition to a special game state that is more advantageous to the player than the normal game state. And setting means for setting a plurality of levels within a predetermined range, and a setting value that determines the level of profit given to the player, and the internal lottery based on the setting value set by the setting means A winning probability defining means for determining the winning probability, a setting changing means for changing a setting value set by the setting means based on the changing operation within the specified range upon receiving a predetermined changing operation, A setting change state for switching between a change operation input means for inputting the change operation to the setting change means, a state in which the change operation can be input to the setting change means, and a state in which the change operation cannot be input. When the switching unit and the setting change state switching unit are switched to a state in which the input of the change operation to the setting change unit is possible, the setting unit sets the setting unit. When the change operation is input to the setting change unit in a state in which the change operation can be input to the setting change unit, the current set value is displayed. When a specific change confirmation operation is received in a state where the change operation can be input to the setting change unit, the setting value candidate switching unit that switches to the setting value that becomes a candidate after the change. Change confirmation means for confirming the set value as a candidate as a setting value changed by the setting change means; power supply means for supplying control voltage power and drive voltage power having different voltages; and the power supply Game control means for controlling the progress of the game using the control voltage power supplied from the supply means, and the control voltage power supplied from the power supply means Game storage means for storing information relating to the progress of the game including the set value set by the setting means and capable of holding the stored information for a certain period after the supply of the control voltage power is stopped And a game operation means for performing an operation relating to the progress of the game using the driving voltage power supplied from the power supply means based on the control by the game control means, and a command signal output from the game control means. Based on the command signal received from the game control means by the effect control means for receiving and controlling the effect operation using the control voltage power supplied from the power supply means, the power supply means Information regarding the control of the rendering operation including the current set value set by the setting means using the supplied voltage power for control. Remembering, and after the supply of the control voltage power is stopped, the storage information can be retained for a certain period of time, and the power supply means is supplied based on the control by the effect control means. The operation operation means for performing the effect operation using the driving voltage power, and the control voltage power supplied from the power supply means and the output voltage of the driving voltage power are individually monitored, and each power Power supply monitoring means for individually outputting a power failure warning signal and operating the effect control means for a period exceeding a predetermined period after the power failure warning signal is output by the power supply monitoring means. In order to maintain a possible state, auxiliary power supply means capable of supplying the control voltage power to the effect control means, and from the power supply monitoring means The progress state of the game including the current set value from the state in which the game control means controls the progress of the game, on condition that either the control voltage power or the driving voltage power is outputted. Is stored in the storage information of the game storage means, and a power failure processing state transition means for transitioning to a state in which processing for preparing to stop the supply of the control voltage power is performed; When a power failure warning signal is output, the effect control means is shifted from a state in which the control of the effect operation is performed to a state in which a process at the time of power failure is performed in preparation for the stop of the supply of the control voltage power, Information on the control of the production operation including the current setting value and the processing for confirming the presence or absence of input of the power failure warning signal of the driving voltage power within a predetermined period of time in the production storage means Special power failure processing state transition means for executing processing to be stored in the information, and when the production control means is shifted to the state of performing the power failure processing by the special power failure processing state transition means, In addition to information related to the control of the rendering operation including the set value, the power failure warning signal input storage means for storing the presence or absence of the power failure warning signal of the driving voltage power from the power supply monitoring means in the storage information of the effect storage means And the supply of the control voltage power is started by the power supply means after the supply of the control voltage power by the auxiliary power supply means is stopped and the game control means and the effect control means stop operating. In the event that the power failure monitoring signal was not input from the power supply monitoring means in the power failure monitoring process performed previously, If that were stored in the storage information of 憶 means, and a fraudulent blackout teaching means for teaching the supply of the control voltage power is stopped improperly.

  In the gaming machine of the present invention, two types of power (control voltage power and drive voltage power) having different voltages are supplied by the power supply means. One control voltage power is mainly used for controlling the game control means and the effect control means, and the other drive voltage power is used for the operation necessary for the progress of the game (such as driving and display of the movable display body, etc.) Used for the performance) and the production operation. In the gaming machine of the present invention, power failure of the control voltage power and drive voltage power is individually monitored, and a separate power failure warning signal is output.

  The set value that determines the level of profit received by the player in stages is set or changed under the management of the game control means. The information of the set value is stored in the game storage means managed by the game control means, and the setting means, the setting change means, the change operation input means, the setting change state switching means, etc. are under the management of the game control means. Play each role. The information on the set value is also stored in the effect storage means managed by the effect control means, but the set value stored in the effect storage means is only when the set value is changed under the control of the game control means. Updated.

  While the control voltage power and the drive voltage power are supplied from the power supply means, the game control means maintains a state in which the progress of the game is controlled using the control voltage power, and from this state, the set value is maintained. However, once the power supply is restarted after the power supply is stopped (after a power failure), the setting change state switching means can accept the change in the setting value. May be in a bad state. Abuse of this mechanism, if an unauthorized person stops the power supply from the power supply means by some means, and further illegally functions the setting change state switching means, change operation input means, setting change means, etc. This makes it possible to change the setting value illegally.

  For this reason, the gaming machine of the present invention employs a configuration that stores as memory information that a power outage may have occurred due to fraud. That is, in the gaming machine of the present invention, there are two systems of power supply, that is, control voltage power and drive voltage power, but since a power failure warning signal is output individually, normally, the power supply is normally supplied by the game hall operator. When stopped (power-off operation), both power failure warning signals should be output simultaneously (or almost simultaneously, almost simultaneously, substantially simultaneously). On the other hand, in the case of fraud, a metal piece or the like is inserted from the outside of the gaming machine main body and the power supply system is short-circuited to cause a power failure, so unless the fraudster short-circuits the two power supplies at the same time, Only one power failure warning signal is output. Therefore, if only one of the power failure notice signals is output when a power failure occurs, the power failure has not occurred normally.

  Therefore, in the gaming machine according to the present invention, the game control means shifts to a state in which the processing at the time of power failure is executed on condition that any one of the control voltage power or the driving voltage power is output. . Through this process, information regarding the progress of the game, including the current setting value, is stored as stored information in the game storage means. One effect control means shifts to the state of executing the process at the time of power failure only on the condition that the power failure notice signal of the control voltage power is output, but here the control of the effect operation including the current set value is performed. In addition to the process of storing information about the process, a process for confirming the presence or absence of the input of the power failure warning signal for the driving voltage power is performed within a predetermined period, and as a result, the control of the rendering operation including the current set value is performed. In addition to the information, the presence or absence of the input of the power failure warning signal of the driving voltage power within the predetermined period is stored as the storage information of the effect storage means. In addition, since the control voltage power is supplied by the auxiliary power supply means for a period exceeding the predetermined period after the power failure warning signal is output, the production control means can complete the above power failure processing within this period. it can.

In the present solution, when the special power failure processing state transition unit shifts to the state in which the effect control unit executes the process at power failure, the following aspects are included.
(1) The effect control means continues to wait for the input of the power failure notice signal of the driving voltage power for a predetermined period, and performs processing for storing information related to the control of the effect operation including the current set value after the predetermined period.
(2) When the blackout notice signal for driving voltage power is input within a predetermined period, the effect control means stores information relating to the control of the effect operation including the current set value without waiting for the elapse of the predetermined period. I do.
(3) The effect control means previously performs processing for storing information related to the control of the effect operation including the current set value, and then confirms whether or not a power failure warning signal for the driving voltage power is input. In this case, the effect control means maintains the standby state until the predetermined period elapses even if the drive voltage power blackout notice signal is input within the predetermined period, or the drive voltage power blackout within the predetermined period. When a warning signal is input, the power failure process is terminated without waiting for the elapse of a predetermined period.

  As described above, when only the control voltage power is interrupted due to an improper power short-circuit or the like, it is possible to put the game control means in a power outage state and change the set value illegally, but the power supply is resumed. At the time, the fact information that the power failure notice signal of the driving voltage power was not input to the game control means at the time of the previous power failure is stored. In this case, the unauthorized power failure teaching means can notify the outside of the gaming machine greatly by teaching the outside of the gaming machine that the previous power failure of the control voltage power was an unauthorized activity.

  Note that the gaming machine according to the present invention is configured such that when the supply of the control voltage power is started to the effect control means after the supply of the control voltage power is stopped, the power supply monitoring is performed in the power failure process performed last time. If it is not stored in the storage information of the effect storage means that the power failure notice signal of the driving voltage power is input from the means, the fact that the supply of the control voltage power is illegally stopped is taught. An unauthorized power failure teaching means may be provided.

  In the gaming machine of the present invention, the difference in profit received by the player due to the difference in the set value is defined as follows. That is, in the gaming machine of the present invention, when the player performs a start operation with the game value applied, a plurality of movable display bodies rotate, and thereafter, when the rotation of all the movable display bodies is stopped by the player's stop operation. The result of the game is determined by the combination of symbols composed of symbols stopped in the symbol display section. That is, in one game in the gaming machine of the present invention, the game value is multiplied, the movable display body in a stopped state is rotated, and then the rotation of the movable display body is stopped. It consists of a series of processes in which the result is always judged when all the movable display bodies are stopped. Therefore, once the result is judged once when all the movable display bodies are stopped, the process of setting the game value or rotating the movable display body after that is the next game. become. In addition, in the game that is played in the normal gaming state, when the symbols corresponding to the special winning type are displayed in a prescribed manner when all the movable display bodies are stopped, the current game ends without giving a gaming value, When it is determined that the symbol corresponding to the special winning type has been displayed in the prescribed mode, the normal gaming state shifts to the special gaming state, so when the game value is multiplied in the next game, it is already in the special gaming state. It has migrated.

  The internal lottery performed for each game is triggered by the player's starting operation. “Internal” here means that the lottery is performed where the player is not aware of the contents of the lottery and the player cannot perceive. This is performed by a control device (control board) to be controlled. As an internal lottery method, random numbers are generated within a predetermined numerical range (within the range from the minimum random number value to the maximum random number value), and one random number is acquired for each game. There is one that determines the lottery result by comparing the value of one random number with a predetermined hit value.

  In the internal lottery, a plurality of types of winning results are prepared, and a random value win value is assigned to each type of winning result. Each winning value has a range (numerical value range) for each type, and if the acquired random number value is within the range of any winning value, it is determined that the type corresponding to that winning value has been won. . In such an internal lottery system, the winning probability for each type of winning result is defined from the ratio of the number of winning values in all random numbers.

  The winning result of the internal lottery performed in one game is maintained at least in the game. Among the multiple types of winning results, there are types where the results are discarded as long as the game is concerned, and there are types where the results are carried over to the next game.

  As a winning result of the internal lottery, at least a small combination with a game value is defined in the gaming machine of the present invention. In addition to such small roles, special winning types are defined as winning results. These small roles and special winning types have corresponding small role symbols and special winning symbols, respectively, and these symbols are respectively assigned to the movable display bodies. That is, the symbols associated with the type of the winning result are included in the symbol row attached to the movable display. The “design” means a picture, a symbol, a mark, a decorative character, or the like that allows the player to visually identify each individual.

  When the small role symbols are stopped in a specific manner when all the movable display bodies are stopped, a specified number of game values are given to the player. The “specific mode” here means the stop position, arrangement, combination, etc. of the symbols in the symbol display section, and generally the corresponding symbols are arranged horizontally or diagonally across a plurality of movable display bodies. It means that Note that there are some small role symbols that need only stop at a position where a corresponding small role symbol for at least a specific movable display body is determined. In any case, if the total number of game values given by the player increases as the number of games increases, the player has obtained the game value for the difference. , You can find joy there.

  The above small role is to give a specified number of game values to the player when the corresponding symbol stops in a specific manner, but apart from this, in the gaming machine of the present invention, a general normal gaming state When the special winning symbol is stopped in a specific manner in this game, the game shifts to a special game state that is more advantageous to the player than the normal game state. By shifting to this special game state, the player is given an opportunity to acquire more game value compared to the normal game state. For this reason, in the gaming machine of the present invention, how to increase the number of times of transition to the special gaming state becomes a turning point of the game, so the player's interest is the special winning symbol when and when It tends to concentrate on what can be arranged in.

  However, the frequency at which the game value can be acquired by the small role and the frequency at which it can shift to the special gaming state depends on the winning probability in the internal lottery after all. The above set values (stepwise settings). Therefore, in the gaming machine of the present invention, the higher the set value is set, the higher the frequency at which the game value can be acquired by the small role and the frequency at which the game value can be shifted to the special game state. It turns out that becomes high.

(Solution 2)
In the solving means 1, the gaming machine of the present invention is in a state where the input of the change operation is impossible by the setting change state switching means when the supply of the control voltage power to the game control means is started. If switched, the game control means is put into a state where the game progress state including the current set value is restored based on the stored information stored in the game storage means, while the change is made by the setting change state switching means. If it is switched to a state in which an operation can be input, the game control means restores the state in which the setting value can be changed by the setting changing means without restoring the game progress state including the current setting value. The set value before the supply of the control voltage power is started by the input of the change operation when the supply of the control voltage power is started when the supply of the control voltage power is started. If changed, a setting value signal indicating the changed setting value is output on condition that the setting change state switching means has switched to a state in which the input of the changing operation is impossible. On the other hand, the game control means A setting value signal output means for outputting a setting value signal representing the current setting value when the game progress state including the current setting value is restored based on the stored information stored in the game storage means; When the supply of the control voltage power is started to the effect control means after the supply of the control voltage power is stopped, the set value is set to the previous line based on the set value signal output by the set value signal output means. A setting change determining means for determining whether or not the setting value stored in the effect storage means has been changed in the process at the time of power failure, and determining that the setting value has been changed by the setting change determining means. In addition, if the power failure monitoring signal input from the power monitoring means was not stored in the storage information of the effect storage means in the power failure monitoring process performed last time, And an unauthorized detection means for detecting that the setting value has been changed.

  In the present solution, when the set value is illegally changed using a technique such as the power short circuit as described above, the fact that the power failure warning signal of the driving voltage power is not input at the previous power failure in the effect storage means Since the condition that the setting value has been saved and the setting value has been changed since the previous power failure is satisfied, it is possible to detect that the setting value has been changed illegally. For this reason, an illegal act can be found on the spot, and a situation in which the game progresses while being changed to a setting value contrary to the intention of the game hall operator is prevented.

(Solution 3)
In the solving means 1 and 2, the gaming machine of the present invention individually supplies the control voltage power and the driving voltage power supplied from the power supply means to the game control means and the effect control means. Two power lines are provided.

  In this solution, it is extremely difficult to short-circuit two independent power supply lines at the same time even when an illegal person actually tries to make a short circuit by bringing a metal piece or the like into contact with the power supply line. . For this reason, it is possible to reliably detect an unauthorized power failure or a setting change based on the fact that the power failure warning signal of the driving voltage power is not input as described above. In addition, this solution means includes an aspect in which two power supply lines are extended from two connectors provided in one power supply device. In such an embodiment, it is almost impossible to simultaneously bring a metal piece or the like into contact with a power supply line of another system, which is a strong defense against fraud.

(Solution 4)
Further, the gaming machine of the present invention has a separate structure. That is, when the gaming machine of the present invention receives a start operation by a player with a predetermined number of game values multiplied for each game, a plurality of movable display bodies having a symbol array formed on the surface are arranged in one direction. Rotating to change the display of the symbol, and then sequentially receiving a plurality of stop operations by the player, the rotation of the movable display body is stopped one by one in the order in which the stop operations are received, and all the movable displays An internal lottery means for performing a predetermined internal lottery for each game and determining a winning result in a gaming machine that determines a game result based on a display mode of a symbol when the body rotation stops; As a result of the internal lottery, a small role defining means for defining a small role with a game value added, and as a result of winning the internal lottery, a special winning type rule for defining a special winning type different from the small role If a symbol corresponding to the small role is displayed in a prescribed manner when all the movable display bodies are stopped in a game played in a general normal gaming state, the number of game values corresponding to the small role is displayed. A game value giving means for giving the player a game value, and a symbol corresponding to the special winning type is displayed in a prescribed manner when all the movable display bodies are stopped in the game played in the normal game state. In addition, a game ending means for ending the current game without giving a game value, and a design corresponding to the special winning type when all the movable display bodies are stopped in the game played in the normal gaming state When the current game is finished without giving a game value by the game ending means, a special game letter that shifts to a special game state that is more advantageous to the player than the normal game state is displayed. Based on the setting means set by the setting means, the setting means for setting the setting value that determines the level of the profit given to the player in a plurality of stages within a predetermined range, the transition means A winning probability defining means for determining the winning probability of the internal lottery, and a setting changing means for changing the set value set by the setting means based on the changing operation within the specified range upon receiving a predetermined changing operation; A change operation input means for inputting the change operation to the setting change means, and a setting for switching between a state in which the change operation can be input to the setting change means and a state in which the change operation cannot be input. When the change state switching unit and the setting change state switching unit switch to a state in which the change operation can be input to the setting change unit, the setting unit sets the setting state. When the change operation is input to the setting change unit in a state in which the change operation can be input to the setting change unit, the setting value display unit that displays the current set value that has been set. When a set value candidate switching unit that switches a set value to a set value that becomes a candidate after change, and when a specific change confirmation operation is accepted in a state in which the change operation can be input to the setting change unit, A change confirmation means for confirming a setting value as a later candidate as a setting value changed by the setting change means; a power supply means for supplying control voltage power and drive voltage power having different voltages; Game control means for controlling the progress of the game using the control voltage power supplied from the power supply means; and the control power supplied from the power supply means. Information about the progress of the game including the set value set by the setting means using power can be stored, and the stored information can be held for a certain period after the supply of the control voltage power is stopped A game storage means, a game operation means for performing an operation relating to the progress of the game using the driving voltage power supplied from the power supply means based on the control by the game control means, and the power supply means The power supply monitoring means for individually monitoring the output voltage of the control voltage power and the drive voltage power and outputting a power failure warning signal individually when the supply of each power is predicted to be stopped, and the power supply monitoring In order to maintain the game control means in an operable state for a period exceeding a predetermined period after the power failure warning signal is output by the means, The auxiliary power supply means capable of supplying the control voltage power to the technique control means, and when the power failure monitoring signal of the control voltage power is output from the power supply monitoring means, the game control means causes the game to proceed. From the state to be controlled, the state of progress of the game including the current set value is saved in the storage information of the game storage means, and the state is shifted to the state of performing the process at the time of power failure to prepare for the stop of the supply of the control voltage power, In this power failure process, a process for confirming the presence or absence of input of a power failure warning signal for the driving voltage power within a predetermined period, and the progress of the game including the current set value are stored in the storage information of the game storage means. A power failure processing state transition means for executing processing, and when the game control means is shifted to a state for performing the power failure processing by the power failure processing state transition means, In addition to the progress of the game including a constant value, the power failure warning signal input storage means for storing the presence or absence of the power failure warning signal of the driving voltage power from the power supply monitoring means in the storage information of the game storage means, and When the supply of the control voltage power is started by the power supply means after the supply of the control voltage power by the auxiliary power supply means is stopped and the operation of the game control means is stopped, the power failure performed last time If it is stored in the storage information of the game storage means that the power supply monitoring means has not received the power failure notice signal from the power supply monitoring means in the time processing, the supply of the control voltage power is illegally stopped. And an unauthorized power failure teaching means for teaching that.

  In the gaming machine (solution 4) of the present invention, two types of power having different voltages (control voltage power and drive voltage power) are supplied by the power supply means. One control voltage power is mainly used for controlling the game control means and the effect control means, and the other drive voltage power is used for the operation necessary for the progress of the game (such as driving and display of the movable display body, etc.) Used for the performance) and the production operation. In the gaming machine of the present invention, power failure of the control voltage power and drive voltage power is individually monitored, and a separate power failure warning signal is output.

  The set value that determines the level of profit received by the player in stages is set or changed under the management of the game control means. The information of the set value is stored in the game storage means managed by the game control means, and the setting means, the setting change means, the change operation input means, the setting change state switching means, etc. are under the management of the game control means. Play each role. The information on the set value is also stored in the effect storage means managed by the effect control means, but the set value stored in the effect storage means is only when the set value is changed under the control of the game control means. Updated.

  While the control voltage power and the drive voltage power are supplied from the power supply means, the game control means maintains a state in which the progress of the game is controlled using the control voltage power, and from this state, the set value is maintained. However, once the power supply is restarted after the power supply is stopped (after a power failure), the setting change state switching means can accept the change in the setting value. May be in a bad state. Abuse of this mechanism, if an unauthorized person stops the power supply from the power supply means by some means, and further illegally functions the setting change state switching means, change operation input means, setting change means, etc. This makes it possible to change the setting value illegally.

  For this reason, the gaming machine (solution 4) of the present invention employs a configuration that stores as a stored information that a power failure may have occurred due to an illegal act. That is, in the gaming machine of the present invention, there are two systems of power supply, that is, control voltage power and drive voltage power, but since a power failure warning signal is output individually, normally, the power supply is normally supplied by the game hall operator. When stopped (power-off operation), both power failure warning signals should be output simultaneously (or almost simultaneously, almost simultaneously, or substantially simultaneously). On the other hand, in the case of fraud, a metal piece or the like is inserted from the outside of the gaming machine main body and the power supply system is short-circuited to cause a power failure, so unless the fraudster short-circuits the two power supplies at the same time, Only one power failure warning signal is output. Therefore, if only one of the power failure notice signals is output when a power failure occurs, the power failure has not occurred normally.

  Therefore, in the gaming machine (solution 4) of the present invention, when a power failure notice signal is output for the control voltage power of the two systems, the game control device controls the progress of the game from the state where the game control device controls the progress of the game. In this process, in addition to the process of saving the progress of the game including the current setting value, the power failure warning signal is input for the other drive voltage power within a predetermined period. As a result, in addition to the progress state of the game including the current set value, the presence or absence of the input of the power failure warning signal of the driving voltage power within a predetermined period is determined in the game storage means. Stored as stored information. In addition, since the power voltage for control is supplied by the auxiliary power supply means for a period exceeding the predetermined period after the power failure notice signal is output, the game control means inputs the power failure notice signal of the driving voltage power within this period. After waiting for, the power failure process can be completed.

In the present solution, the following modes are included when the game control unit shifts to a state where the power failure process state shift unit executes the process during a power failure.
(1) The game control means continues to wait for the input of a power failure notice signal for driving voltage power for a predetermined period, and performs a process of saving the progress state of the game including the current set value after the lapse of the predetermined period.
(2) The game control means, when a power failure warning signal of driving voltage power is input within a predetermined period, performs a process of saving the game progress state including the current set value without waiting for the elapse of the predetermined period. .
(3) The game control means first performs a process of storing the progress state of the game including the current set value, and then confirms whether or not a power failure warning signal for driving voltage power is input. In this case, the game control means maintains the standby state until the predetermined period elapses even if the driving voltage power blackout notice signal is input within the predetermined period, or the driving voltage power blackout within the predetermined period. When a warning signal is input, the power failure process is terminated without waiting for the elapse of a predetermined period.

  As described above, when only the control voltage power is interrupted due to an improper power short-circuit or the like, it is possible to put the game control means in a power outage state and change the set value illegally, but the power supply is resumed. At the time, the fact information that the power failure notice signal of the driving voltage power was not input to the game control means at the time of the previous power failure is stored. In this case, the unauthorized power failure teaching means can notify the outside of the gaming machine greatly by teaching the outside of the gaming machine that the previous power failure of the control voltage power was an unauthorized activity.

  In the gaming machine (solution 4) of the present invention, the supply of the control voltage power by the auxiliary power supply means is stopped and the operation of the game control means is stopped. When the supply is started, it was stored in the storage information of the game storage means that the power supply monitoring means had received a power failure warning signal from the power supply monitoring means in the previous power failure process. In this case, an unauthorized power failure teaching means for teaching that the supply of the control voltage power is illegally stopped may be provided.

  In the gaming machine (solution 4) of the present invention, the difference in profit received by the player due to the difference in setting value is defined as follows. That is, in the gaming machine of the present invention, when the player performs a start operation with the game value applied, a plurality of movable display bodies rotate, and thereafter, when the rotation of all the movable display bodies is stopped by the player's stop operation. The result of the game is determined by the combination of symbols composed of symbols stopped in the symbol display section. That is, in one game in the gaming machine of the present invention, the game value is multiplied, the movable display body in a stopped state is rotated, and then the rotation of the movable display body is stopped. It consists of a series of processes in which the result is always judged when all the movable display bodies are stopped. Therefore, once the result is judged once when all the movable display bodies are stopped, the process of setting the game value or rotating the movable display body after that is the next game. become. In addition, in the game that is played in the normal gaming state, when the symbols corresponding to the special winning type are displayed in a prescribed manner when all the movable display bodies are stopped, the current game ends without giving a gaming value, When it is determined that the symbol corresponding to the special winning type has been displayed in the prescribed mode, the normal gaming state shifts to the special gaming state, so when the game value is multiplied in the next game, it is already in the special gaming state. It has migrated.

  The internal lottery performed for each game is triggered by the player's starting operation. “Internal” here means that the lottery is performed where the player is not aware of the contents of the lottery and the player cannot perceive. This is performed by a control device (control board) to be controlled. As an internal lottery method, random numbers are generated within a predetermined numerical range (within the range from the minimum random number value to the maximum random number value), and one random number is acquired for each game. There is one that determines the lottery result by comparing the value of one random number with a predetermined hit value.

  In the internal lottery, a plurality of types of winning results are prepared, and a random value win value is assigned to each type of winning result. Each winning value has a range (numerical value range) for each type, and if the acquired random number value is within the range of any winning value, it is determined that the type corresponding to that winning value has been won. . In such an internal lottery system, the winning probability for each type of winning result is defined from the ratio of the number of winning values in all random numbers.

  The winning result of the internal lottery performed in one game is maintained at least in the game. Among the multiple types of winning results, there are types where the results are discarded as long as the game is concerned, and there are types where the results are carried over to the next and subsequent games.

  As a winning result of the internal lottery, at least a small part accompanied by a game value is defined in the gaming machine of the present invention. In addition to such small roles, special winning types are defined as winning results. These small roles and special winning types have corresponding small role symbols and special winning symbols, respectively, and these symbols are respectively assigned to the movable display bodies. That is, the symbols associated with the type of the winning result are included in the symbol row attached to the movable display. The “design” means a picture, a symbol, a mark, a decorative character, or the like that allows the player to visually identify each individual.

  When the small role symbols are stopped in a specific manner when all the movable display bodies are stopped, a specified number of game values are given to the player. The “specific mode” here means the stop position, arrangement, combination, etc. of the symbols in the symbol display section, and generally the corresponding symbols are arranged horizontally or diagonally across a plurality of movable display bodies. It means that Note that there are some small role symbols that need only stop at a position where a corresponding small role symbol for at least a specific movable display body is determined. In any case, if the total number of game values given by the player increases as the number of games increases, the player has obtained the game value for the difference. , You can find joy there.

  The above small role is to give a specified number of game values to the player when the corresponding symbol stops in a specific manner, but apart from this, in the gaming machine of the present invention, a general normal gaming state When the special winning symbol is stopped in a specific manner in this game, the game shifts to a special game state that is more advantageous to the player than the normal game state. By shifting to this special game state, the player is given an opportunity to acquire more game value compared to the normal game state. For this reason, in the gaming machine of the present invention, how to increase the number of times of transition to the special gaming state becomes a turning point of the game, so the player's interest is the special winning symbol when and when It tends to concentrate on what can be arranged in.

  However, the frequency at which the game value can be acquired by the small role and the frequency at which it can shift to the special gaming state depends on the winning probability in the internal lottery after all. The above set values (stepwise settings). Therefore, in the gaming machine of the present invention, the higher the set value is set, the higher the frequency at which the game value can be acquired by the small role and the frequency at which the game value can be shifted to the special game state. It turns out that becomes high.

(Solution 5)
In the solving means 4, the gaming machine of the present invention is in a state in which the change operation cannot be input by the setting change state switching means when the supply of the control voltage power to the game control means is started. If switched, the game control means is put into a state where the game progress state including the current set value is restored based on the stored information stored in the game storage means, while the change is made by the setting change state switching means. If it is switched to a state in which an operation can be input, the game control means restores the state in which the setting value can be changed by the setting changing means without restoring the game progress state including the current setting value. When power supply state switching means and supply of the control voltage power to the game control means are started, a setting value can be changed by the power recovery state switching means. When the setting change state switching means switches from the state in which the input of the change operation is possible to the state in which the input of the change operation is impossible, the supply of the control voltage power is started before A setting change determining means for determining whether or not a setting value stored in the game storage means has been changed by the setting changing means; a setting change determining means for determining that the setting value has been changed by the setting change determining means; When the power failure monitoring signal input from the power supply monitoring means in the power failure monitoring process is not stored in the storage information of the game storage means, the abnormal setting value is changed. It further comprises fraud detection means for detecting what happened.

  In this solution, when the setting value is illegally changed using a technique such as a power supply short circuit as described above, the setting value changing operation can be changed to a state where the changing operation cannot be input. The fact that the power voltage warning signal for driving voltage power was not input at the previous power failure was stored in the game storage means, and the condition that the set value was changed from the previous power failure is satisfied Therefore, it is possible to make the surroundings aware that the setting value has been changed illegally. For this reason, an illegal act can be found on the spot, and a situation in which the game progresses while being changed to a setting value contrary to the intention of the game hall operator is prevented.

(Solution 6)
In the solution 5, the gaming machine according to the present invention may be configured such that when it is detected by the fraud detection means that an abnormal set value has been changed after the supply of the control voltage power is started, the game control means The game further stop means for stopping the control of the progress of the game is further provided.

  In this case, it is possible to effectively prevent a situation in which the game progresses while an abnormal setting value is changed in addition to the detection of fraud.

(Solution 7)
In the solving means 4 to 6, the gaming machine of the present invention is a two-system power supply that individually supplies the control voltage power and the driving voltage power supplied from the power supply means to the game control means. With lines.

  In this solution, it is extremely difficult to short-circuit two independent power supply lines at the same time even when an illegal person actually tries to make a short circuit by bringing a metal piece or the like into contact with the power supply line. . For this reason, it is possible to reliably detect an unauthorized power failure or a setting change based on the fact that the power failure warning signal of the driving voltage power is not input as described above. This solving means includes an aspect in which two power supply lines extend from two connectors provided in one power supply device. In such an embodiment, it is almost impossible to simultaneously bring a metal piece or the like into contact with a power supply line of another system, which is a strong defense against fraud.

(Solution 8)
In the solving means 1 to 7, the game control means includes a control circuit that plays a central role in controlling the progress of the game, and a storage circuit that plays the role of the game storage means by storing the stored information. And a voltage conversion device that converts the control voltage power supplied from the power supply means into circuit voltage power used in the control circuit and the storage circuit. In this case, the circuit voltage power converted by the voltage converter is lower than the control voltage power of the conversion source.

  Such an aspect is particularly effective for voltage drop in the power supply path and noise intervention. That is, a control voltage power is supplied to a hardware unit having a control circuit and a memory circuit at a relatively high voltage, and is converted into a relatively low voltage power by a voltage conversion device in the hardware unit. If it is a structure, the influence of the voltage drop in the electric power supply path on the way will be excluded, and required electric power can be used with the stable voltage.

  In addition, regardless of the specific arrangement of the hardware units inside the gaming machine main body, it is not necessary to consider the voltage drop due to the difference in the length of the power supply path, increasing the degree of freedom in the arrangement of the hardware units for each model. There is an advantage.

  Furthermore, even if noise intervenes in the supply path of the driving voltage power having a relatively high voltage, the influence of the noise is reduced when converted to a relatively low voltage by the voltage conversion device. Therefore, the structure is advantageous for a gaming machine used in a noisy environment.

  The gaming machine of the present invention can improve the discoverability of fraud by performing backup control against fraud.

Therefore, from the main control board 92, drive pulse signals for controlling the drive (rotation / stop) of the reel drive motors 88a, 88b, and 88c are individually provided. Is output.

  Further, the slot machine 1 has a left reel position sensor 106a, a middle reel position sensor 106b, and a right reel position sensor 106c in order to detect a reference position related to the rotation of each reel 10a, 10b, 10c. Detection signals (reference position signals) from 106a, 106b, and 106c are input to the main control board 92. Based on this detection signal, the main control board 92 determines the position relating to the rotation of each reel 10a, 10b, 10c (which position is present in the display window 6), and which symbol is displayed when it is stopped. Control of whether to stop on the effective line, that is, reel control can be executed.

  When it is necessary to pay out medals when the reels 10a, 10b, and 10c are stopped, the main control board 92 outputs a drive signal (ON signal) to the hopper device 78 to control to drive the payout motor. On the other hand, a payout sensor 98 is built in the hopper device 78, and the payout sensor 98 detects a actually paid out medal and outputs a detection signal to the main control board 92. When the actual payout number reaches the specified payout number, the main control board 92 stops driving the payout motor.

  On the other hand, the slot machine 1 includes a medal full sensor 86, and when a certain amount of medals accumulates in the medal auxiliary storage 84, a detection signal is output from the medal full sensor 86. Upon receiving this detection signal, the main control board 92 determines that a failure has occurred, temporarily stops the progress of the game, and performs a process of displaying an error code on the payout number display section (error display section) 34 described above.

  On the other hand, on the back side of the front door 4, an error release sensor 100 is installed integrally with the lock device. The employee of the hall can perform the error canceling operation by twisting it in the counterclockwise direction with the dedicated key inserted into the key cylinder part 48, and when such an error canceling operation is performed, A detection signal is output from the error cancellation sensor 100. The main control board 92 can stop the display of the error code and continue the game if it is determined based on each detection signal that the failure such as the full of medals has been removed and the error canceling operation has been performed. To return to the correct state (error release). In this case, the medal full tank is given as an example of failure, but in addition to this, for various failures, inserted medal passage time error (medal retention), inserted medal passage check error (duplication detection, etc.), inserted medal retrograde There are errors (reverse in the medal insertion passage), hopper empty error (medal out of service), hopper jam error (medal jammed in the hopper), illegal hit error (reel control failure), and the like.

  A medal insertion passage is formed in the back of the front door 4 (inside the main body 2) behind the insertion slot 26, and an insertion sensor 104 and a lockout solenoid 102 are installed in the middle of the medal insertion passage. Has been. The insertion sensor 104 detects medals inserted from the medal insertion slot 26 and outputs a detection signal to the main control board 92. Based on the detection signal from the insertion sensor 104, the main control board 92 determines whether or not the inserted medal has normally passed through the medal insertion passage (determination of time and direction required for passing). One lockout solenoid 102 serves to open and close the medal insertion passage. The lockout solenoid 102 closes the medal insertion passage when it is in an inoperative state, but when activated, the lockout solenoid 102 opens the medal insertion passage so that the medal insertion can be accepted.

  On the other hand, when the lockout solenoid 102 is deactivated, the medal insertion path is closed and the insertion of medals is not accepted, and even if the player inserts medals, it is returned to the tray 54 as it is. As a result, neither bet / credit addition by medal insertion is performed.

(3-2. External terminal board)
An external terminal board 96 is connected to the main control board 92, and the slot machine 1 is connected to the hall computer 108 via the external terminal board 96. The external terminal board 96 relays various signals (game status indicating BB, RB, etc.) transmitted from the main control board 92 to the hall computer 108 in addition to the medal in / out signal (injection medal signal and payout medal signal). ing. “BB” is an abbreviation for a big bonus and “RB” is an abbreviation for a regular bonus. In the present embodiment, both are the same as known contents.

(3-3. Sub-control board [production control means])
On the sub-control board 94, a CPU 118, a ROM 120, a RAM 122, a VDP (Video Display Processor) 124, an audio amplifier 126, a sound source IC 128 (sound equipment), and the like are mounted. The sub control board 94 controls the display of images by the liquid crystal display device 58 and the operation of the speaker 56 based on the command signal transmitted from the main control board 92, as well as the lamps (LEDs) 60, 62, 64. Controlling lighting or flashing.

  Further, the sub control board 94 receives a command signal (medal insertion sound command, bet operation sound command, payout sound command, etc.) transmitted from the main control board 92 and receives the liquid crystal display device 58, the speaker 56, the lamps 60, 62,. It is also possible to execute 64 controls.

  On the rear surface of the front door 4, a reel illumination light 142 for illuminating the surfaces of the left reel 10a, the middle reel 10b, and the right reel 10c is provided, and this reel illumination light 142 together with the reel backlight 144 described above. The lighting state is controlled by the sub-control board 94. The reel illumination light 142 is composed of white illumination such as a cold cathode tube, and is disposed on the back side of the upper edge of the display window 6 so as to illuminate the left reel 10a, the middle reel 10b, and the right reel 10c evenly.

(3-4. Power supply unit [Power supply means])
The power supply unit 70 takes in electric power from an external power supply (for example, AC 100 V) and generates electric power (for example, DC 24 V, 12 V) necessary for the operation of the slot machine 1. Although not shown in FIG. 3, in this embodiment, two power supply wirings (power supply lines) are connected from the power supply unit 70 to the main control board 92 and the sub control board 94, respectively. Electric power (DC 24 V, 12 V) having different voltages is supplied. The operation power necessary for the reel drive motors 88a, 88b, 88c, the hopper device 78, and various effect elements is supplied via the main control board 92 or the sub control board 94, respectively. The two power sources will be further described later.

  The power supply unit 70 also includes a setting key switch 72, a reset switch 74, a power switch 76, and the like. None of these switches are exposed to the outside of the main body 2 and can be operated only by opening the front door 4. Among these, the power switch 76 is for turning on / off the power supply to the slot machine 1, and the setting key switch 72 is for changing the setting of the slot machine 1 (setting values 1 to 6). Yes (setting change state switching means). The reset switch 74 is used to cancel an error that has occurred in the slot machine 1 and is operated together with the setting key switch 72 to change the setting. The setting change is for changing the payout rate of the slot machine 1 (ratio of the payout number to the input number) in stages, and usually the lowest payout rate at the setting 1 (setting value is 1). , Setting 6 (setting value is 6) is the highest payout rate. It should be noted that such a setting change is performed by a game hall manager (setting change means, change operation input means).

  A door opening sensor 132 is installed inside the main body 2, and when the front door 4 is opened, a detection signal is output from the door opening sensor 132. The main control board 92 can determine the open / closed state of the front door 4 based on the detection signal from the door open sensor 132. When the main control board 92 determines that the front door 4 is in the open state, a signal indicating that is sent to the external terminal. It can be transmitted from the board 96 to the hall computer 108.

(4. Game processing)
Next, the flow of game processing in the slot machine 1 will be described. The following game processing proceeds in accordance with a processing procedure on a control program executed by the CPU of the main control board 92.

(4-1. Revolute game processing)
FIG. 4 shows one processing procedure for one basic game (rotation game) in the slot machine 1. One game starts from start processing (step S10). This starting process is a process for starting the rotation of the reels 10a, 10b, and 10c. Here, a random number lottery is performed in response to the insertion of a medal or the operation of the bet buttons 12 and 16 or the operation of the start lever 18. Or other processing is performed. The details of the starting process (step S10) will be described later using another flowchart.

  In one game, a stop process (step S20) is executed following the start process (step S10). This stop process is to stop the rotation of each of the reels 10a, 10b, 10c and control the stop position. This process corresponds to a process generally called “reel control”. Generally, there are two types of reel control, a table method and a control method, but in this embodiment, the table method is used. This stop process will also be described later using another flowchart.

  When the rotation of the reels 10a, 10b, and 10c is stopped by the stop process, a determination process (step S30) is performed next. This determination process determines the combination mode (or stop mode, display mode, and appearance) of the symbols displayed when all reels 10a, 10b, and 10c are stopped. It is for providing game results.

(4-2. Examples of symbol combinations)
The combination of the prescribed symbols determined in the stop process includes, for example, a combination of three symbols of the same type (for example, “bell”, “watermelon”, “replay”, “7”, “BAR”, etc.) There are combinations of types of symbols (for example, “7-7-BAR”). In addition, as long as one type of symbol (for example, “cherry”) is present at the position of the left end (displayed on the left reel 10a), the type of the other two symbols (middle symbol / right symbol) is not limited. A single symbol combination (often written as “cherry-ANY-ANY” or the like) is also defined.

(4-3. Game results and benefits)
In addition, the benefits given to the player as a game result include, for example, payout of medals, transition to various bonus games, replay (replay), and the like. In general, a combination of symbols in which medals are paid out is referred to as a “small role”, and a symbol constituting the combination is referred to as a “small role symbol” or the like. Replay (replay) allows the next game to be played with the same multiplier as that game, and the corresponding combination is called “replay”, and the symbols constituting the combination are “replay symbols”. Or the like. Furthermore, a symbol constituting a combination that triggers a transition to a bonus game is referred to as a “bonus symbol” or the like. The specific contents of the determination process will also be described using another flowchart after the stop process.

(4-4. Start-up process)
FIG. 5 specifically shows the contents of the start process. Here, first, the insertion of medals or the operation of the bet buttons 18, 20, and 22 is awaited (step S101). As long as the player does not insert a medal or performs a betting operation (No), the start lever 18 is not activated, so the determination in Step S104 is denied (No) and the standby state (Step S101) continues to be looped. When a medal is inserted or a bet operation is received, a reception process (step S102) is performed, and the bet lamps 42a, 42b, and 42c are turned on according to the number of bets. In the acceptance process (step S102), a medal insertion command or a bet command is transmitted from the main control board 92 to the sub control board 94.

  The number of medals that can be multiplied in a normal game, that is, the number of bets, can be selected by the player within a range of 1 to 3, or only 3 (3 There is also a dedicated). In the game of the slot machine 1, the difference in the number of bets becomes the difference in the number of effective lines defined in the display window 6. Also, if the number of bets is different, the winning probability of the internal lottery is different except during the bonus game (JAC game). Normally, three symbols are effectively displayed in the vertical direction for each reel 10a, 10b, 10c in the display window 6, so that nine symbols are arranged in a matrix in the display window 6 as a whole. The line is a virtual line for defining a direction in which three symbols arranged in the display window 6 are viewed as one combination.

  For example, if the number of bets is 1, there is only one effective line, and the effective line in this case is defined in the horizontal direction at the middle position of the matrix. When the number of bets is increased to two, two horizontal effective lines are added to the upper and lower positions in addition to the middle position, and a total of three effective lines are defined. Then, when the number of bets reaches the maximum (= 3), two right-up and right-down effective lines, which are a combination of symbols in an oblique direction, are added, and five effective lines are defined in total. These effective lines are all linear, but there are cases where an effective line that is bent in the middle is defined in addition to these, and these are called “anomalous lines” or the like.

  In any case, the start lever valid process (step S103) is performed following the medal insertion or bet operation acceptance process (step S102), and the operation of the start lever 18 is substantially validated for the first time. When the player operates the start lever 18 (start operation) in this state, the determination in step S104 is affirmed (Yes), and then the start lever invalidation process (step S105) is performed.

  When the start lever 18 is operated, random numbers are extracted in response to the operation (step S106). The random number used here may be either a software random number or a hardware random number. Further, the timing for extracting the random number after receiving the operation of the start lever 18 is not particularly defined, and an appropriate extraction timing can be set in the programming process.

  In the next flag process (step S107), an internal lottery is performed using the extracted random number. The ROM 112 stores a lottery table in which the winning value of the internal lottery is determined, and the winning values of various small roles, replays, and various bonuses are determined in advance in the lottery table. Accordingly, the winning probabilities of various small roles, replays, and various bonuses are determined by the number of winning values among all random numbers (for example, 0 to 65535). Further, the winning probability (the number of winning values the lottery table has) varies depending on the setting of the slot machine 1, and generally, a lottery table is used in which the winning probability increases as the set value increases (winning probability defining means). Here, the term “internal” refers to the fact that a lottery is performed in the control process of the main control board 92, and the contents of the lottery (specific random number value, winning value, etc.) are felt by the player. It is something that has not been obtained. In any case, in the flag processing, winning / losing is determined from the extracted random number value, and a flag corresponding to the type of winning result (for example, big bonus, regular bonus, small role, replay, etc.) is turned ON, A winning flag command is transmitted from the main control board 92 to the sub control board 94. Note that when a lottery is lost, a flag indicating a loss (loss) is turned ON. Further, when the random number value extracted in step S106 corresponds to a special loss, a flag indicating the special loss may be turned on.

  When the above flag processing (step S107) is performed, it is determined whether or not the wait timer started in the previous start processing has timed up (for example, 4.1 seconds have elapsed) (step S108). When the time-up (Yes) is confirmed, each reel 10a, 10b, 10c is started, that is, rotation by the reel motor is started (step S109), and a wait timer from here to the next start is started (step S109). S110).

  When the above processing is performed, the start processing in FIG. 5 is returned, and then the reel stop processing is executed.

(4-3. Reel stop processing)
FIG. 6 shows the contents of reel stop processing by the table method as an example. Since a known technique can be basically applied to the reel control, the process flow will be briefly described here.

  As shown in FIG. 6, in the reel stop process, first, a reel control table is selected according to a flag indicating the winning result at that time (step S201). A reel control table is prepared for all winning results in advance, and these are stored in the ROM 112 of the main control board 92 as read-only table data.

  When the reel control table is selected, the next procedure is in a standby state until one of the three stop buttons 20, 22, 24 is pressed (steps S202, S210, S217). That is, in these standby states, it is determined whether the left, middle, and right reels 10a, 10b, and 10c are rotating (stop flag = 0?). It is determined whether any one of the stop buttons 20, 22, 24 has been pressed. If none of the stop buttons 20, 22, 24 has been pressed yet, the determinations at steps S 202, S 210, S 217 are all denied (No). Further, since all the reels 10a, 10b, and 10c are not stopped at this stage, the determination in step S209 is negative (No), and step S202 and subsequent steps are repeated.

  When the player performs a stop operation, that is, when each stop button 20, 22, 24 is pressed, the following processing is performed. In the present embodiment, the stop buttons 20, 22, and 24 can be pressed in the order desired by the player.

  For example, if the left stop button 20 is first pressed in accordance with a so-called “forward push” or “forward scissor push” procedure (step S202 = Yes), the first reel stop flag is not set at this time ( Therefore, the first reel stop process (step S204) is executed for the left reel 10a. Here, the “first reel stop process” means a process for stopping the reel first.

  Alternatively, when the center stop button 22 is first pressed in accordance with a so-called “middle push” procedure (step S210 = Yes, step S211 = Yes), the first reel stop process (step S212) is executed for the middle reel 10b. The

  In addition to this, when the right stop button 24 is first pressed in accordance with a so-called “reverse push” or “reverse scissor push” procedure (step S217 = Yes, step S218 = Yes), the right reel 10c is A one reel stop process (step S219) is executed.

  As described above, when the first reel stop process (steps S204, S212, and S219) is performed for any one of the left, middle, and right reels 10a, 10b, and 10c, the reel control tables for the remaining two reels are determined. (Steps S206, S214, S221). For example, if the winning type at that time is “BELL”, the reel control table for stopping the symbols of “BELL” on the predetermined effective lines for the remaining two reels (10a, 10b, 10c), respectively. Is determined. Based on the reel control table determined here, the stop positions of the remaining two reels (10a, 10b, 10c) are controlled (steps S205, S213, S220). As a result, the symbol “bell” is stopped on the predetermined effective line.

  For example, taking a pattern in which the left reel 10a is stopped first along the forward pressing procedure, the first reel stop process is performed on the left reel 10a in step S204. At this time, the main control board 92 transmits a stop information command (first stop information command) indicating the stop eye of the left reel 10a to the sub control board 94.

  In the next step S206, reel control tables (stop tables) are determined for the remaining middle and right reels 10b and 10c. Specifically, when the winning flag represents “bell” and the left reel 10a is in the first stop, first, the process of stopping the symbol “bell” at the upper position is performed. When the left reel 10a is stopped for the first time, the effective line is determined to be a right-down line. The remaining middle reel 10b is set at the interruption position, and the left reel 10c is set at the lower position. A reel control table for stopping is determined (step S206).

  When the above processing (step S206) is performed, the first reel stop flag is turned ON (= 1) (step S207), and the left reel stop flag is turned ON (= 1) (step S208). ). Since all the reels are not stopped at this stage, the determination in step S209 is negative (No), and the process returns to step S202.

  Then, since the left reel 10a has already stopped at this time (step S202 = No), when the stop button 22 at the center position is pressed second (step S210 = Yes) according to the forward pressing procedure, the first reel stops. After the flag determination (step S211 = No), the middle reel stop process (step S213) is executed. In the middle reel stop process, the stop position is controlled based on the reel control table (stop table) previously determined for the middle reel 10b. As a result, in the example of the lower right effective line, the symbol “bell” on the middle reel 10b stops at the middle position.

  In addition, the stop eye at this time (display mode at the time of stop) is a state in which two symbols “bells” are aligned on the left and middle reels 10a and 10b on the right lowering line (so-called “right lowering temper”). At this time, the main control board 92 transmits a stop information command (second stop information command) indicating the stop eye of the middle reel 10b to the sub control board 94. In this case, since the middle reel 10b is in the second stop, steps S212, S214, and S215 are all bypassed, and the middle reel stop flag is only turned ON (= 1) in step S216.

  Similarly, when the right stop button 24 is finally pressed (step S217 = Yes), the stop position is controlled based on the reel control table (stop table) already determined for the right reel 10c (step S220). ). As a result, the symbol “bell” on the third right reel 10c stops at the lower position, so that the appearance (display mode) when all reels are stopped is a combination of three symbols “bell” on the lower right line. Is displayed.

  At this time, the main control board 92 transmits a stop information command (third stop information command) indicating the stop eye of the right reel 10c to the sub control board 94. In this case, since the right reel 10c is in the third stop, steps S219, S221, and S222 are all bypassed, and the right reel stop flag is turned ON (= 1) in step S223.

  When the all-reel stop flag is turned on through the processing so far, the determination in step S209 is affirmed (Yes), and the processing by the main control board 92 exits this routine.

  Although not particularly illustrated, in this embodiment, a certain number (for example, 4 to 6) of symbols “bells” are arranged in all the symbols (for example, 21) on each reel 10a, 10b, 10c. Furthermore, only about four other types of symbols are arranged between the symbols of “bell” in each symbol row. Therefore, in the first reel stop process (steps S204, S212, and S219) for the left, middle, and right, even if the timing at which the player presses the stop buttons 20, 22, and 24 is not so severe, the reel control is performed. The “bell” symbol can be reliably stopped on the active line. Also, in each reel stop process after the second stop (steps S205, S213, and S220), even if the pressing timing of the stop buttons 20, 22, and 24 is not so severe, it is on the effective line determined by the first reel stop. It is possible to reliably stop the “bell” symbol.

  As a result, when the small role “Bell” is won by an internal lottery, a combination of “Bell” symbols is displayed simply by the player pressing the stop buttons 20, 22, 24. And there is an advantage that the player can surely win a medal. In the present embodiment, the same applies to “replay”.

  The above is the flow of the reel stop process using the reel control table. As described above, in this embodiment, one effective line is preliminarily determined depending on whether the first stop reel corresponds to the left, middle, or right. For the remaining reel stop processing of the second and third stops, a reel control table prepared for stopping the symbol corresponding to the winning flag on this effective line is used.

(4-4. Composition of roles)
In the present embodiment, the symbol “watermelon” is attached in addition to the symbol “bell” in the symbol row of each reel 10a, 10b, 10c. With respect to these “bells” and “watermelons”, when all the reels 10a, 10b, and 10c are stopped, three symbols of the same type are stopped on the active line, thereby giving out a prescribed number of medals. In this embodiment, for example, there are 8 “Bell” payouts and 12 “Watermelon” payouts, such as “Bell” and “Watermelon”. What can receive is "general small role design".

  On the other hand, with regard to “cherry”, it is not necessary that all the symbols “cherry” are stopped on the active line when all the reels 10a, 10b, 10c are stopped, and “cherry” is only applied to the left reel 10a. If the symbol is stopped on the active line, a prescribed number of medals are paid out regardless of the stopping mode of the other middle reel 10b and right reel 10c. In this embodiment, the payout of “cherry” is, for example, 7 sheets, but when the symbol of “cherry” stops at the upper position in the state of 3 sheets, it is stopped at both the upper line and the lower right line. In addition, when the “cherry” symbol stops at the lower position, it stops at both the lower line and the right-up line (so-called “double winning”). Therefore, the “cherry” symbol can be paid out twice as many as the specified number (14 in this case). In the present embodiment, a symbol that can be paid out with only one symbol, such as “cherry”, is a “specific small role symbol”.

  In this embodiment, the symbol “7” or “BAR” corresponds to the “bonus symbol”. These “7” or “BAR” are “Big Bonus Game” and “Regular Bonus Game” when all three reels 10a, 10b and 10c are stopped when all three symbols of the same type are stopped on the active line. The player is given the benefit of shifting to a special gaming state called, but medals are not paid out because the symbols are ready. Like these “7” and “BAR”, a symbol corresponding to a special winning type is one in which three types of symbols of the same type are arranged to shift to various bonus games.

  The above “replay” is a symbol corresponding to replay, and when all three reels 10a, 10b, and 10c are stopped when all three “replay” symbols are stopped on the active line, the next game again. Replays can be performed under the same multiplier conditions without medals. In the present embodiment, the “replay” symbol is a “replay symbol”. In the present embodiment, the “replay” symbol is also used as the “JAC symbol” in the “big bonus game”.

(4-5. Determination process)
The above is the content of the reel stop process. When all the reels 10a, 10b, and 10c are stopped by the reel stop process, the following determination process is performed.

  FIG. 7 specifically shows the contents of the determination process. When all the reels 10a, 10b, and 10c are stopped by the reel stop process (FIG. 6), the main control board 92 displays the output (stop mode, display mode) displayed at that time on the sub control board 94. Transmit (step S301).

  Next, from the outcome when all reels are stopped, whether or not the big bonus symbol “7” is stopped on the active line at that time (step S302), the regular bonus symbol “BAR” is aligned. (Step S303), whether or not the small role symbols ("bell", "watermelon", "cherry") have been stopped together (step S304), and whether the "replay" symbol has stopped. (Step S305) is determined. In the case of “cherry”, it is only necessary to determine the left reel 10a.

  At this time, if it is determined that the small role symbols (“bell”, “watermelon”, “cherry”) have stopped on the active line (step S304 = Yes), the main control board 92 drives the hopper device 78 to A medal payout operation corresponding to the number of small roles is instructed, and a payout sound command is transmitted to the sub-control board 94 (step S308).

  In addition, the sub control board 94 has the symbols aligned by blinking the reel backlight 144 at positions corresponding to the symbols on the effective line or blinking the lamps 60, 62, 64 of the front door 4 ( (Also called “winning”). In addition, the sub-control board 94 performs an effect of outputting sound effects from the speaker 56.

  If it is determined that “7” as a big bonus symbol or “BAR” as a regular bonus symbol is all stopped on the active line (step S302 or S303 = Yes), the main control board 92 is a sub-control board. A sound effect command is transmitted to 94 (steps S306 and S307), and a big bonus game process (step S309) or a regular bonus / JAC game process (step S310) is executed. As described above, when it is determined that the bonus symbol “7” or “BAR” is stopped in a game that is being played normally, the game is terminated without paying out medals (giving game value). (Game end means). In addition, when the big bonus game process (step S309) or the regular bonus / JAC game game process (step S310) is executed, when the game is finished, the game is shifted to a special game state before the next bet is placed (so-called an actor operation) ) (Special gaming state transition means).

  Alternatively, when it is determined that the symbols “Replay” are stopped on the active line (step S305 = Yes), the replay process (step S311) is executed. The contents of the replay process are the same as known ones.

  When the above processing is completed, the winning combination of the small role or replay is turned off (step S312), and this determination processing is returned. Here, the flag in the case of a loss is also turned off. In addition, even if the winning flag for the small role is ON, if the symbol is not stopped on the active line due to missing or the like (steps S304, S305 = No), the winning flag is similarly turned OFF and the determination processing is performed. Returned. It should be noted that the winning flag for the big bonus or the regular bonus is not turned off in this determination process even if the player cannot arrange the corresponding bonus symbols (steps S302 to S305 = No) and is carried over to the next game. It is. When the process proceeds to the big bonus game process (step S309) or the regular bonus / JAC game game process (step S310), the winning flags for various bonuses are turned OFF during these processes.

  As described above, in this embodiment, the “cherry”, “bell”, “watermelon”, and “replay” flags are discarded as long as the game is concerned, and are not carried over to the next game (the same applies to the defeat flag). . On the other hand, the bonus flag “7” or “BAR” is not discarded as long as the game is concerned, and can be carried over to the next time.

(5. Special gaming state)
The above is the explanation during the normal game, but in the slot machine 1 of the present embodiment, the big bonus or the regular bonus is won by the internal lottery in the game during the normal game, and the corresponding “7” or “BAR” symbol is displayed. When all of them stop on the active line, the game moves to a special game state called “Big Bonus Game” or “Regular Bonus Game”. In the present embodiment, an opportunity to play a maximum of 30 regular games in one big bonus game and an opportunity to play a maximum of 3 JAC games (regular bonus games) are included. Through these game opportunities, the player may receive a medal payout at a relatively high frequency, and thus it can be said that the player is more advantageous than usual.

(5-1. Big bonus game processing)
FIG. 8 specifically shows the contents of the big bonus (BB) game process. Here, first, initialization processing is performed (step S401), but the random value lottery winning value table is not changed particularly for the base game (small role game). Therefore, in the normal game with a big bonus, a winning value table that defines the same winning probability as that in the normal gaming state is used (small role probability fixing means).

  Next, the big bonus winning flag is turned off (step S402), and then the start processing (step S403) and stop processing (step S404) of all the reels 10a, 10b, 10c are executed. The contents of the start process and the stop process are the same as those already described.

  When all the reels 10a, 10b, and 10c are stopped by the stop process, the symbol combination mode at that time, that is, the outcome (stop mode) is transmitted to the sub-control board 94 (step S405), and then to the RAM 114 of the main control board 92. Only one reserved small game counter is counted up (step S406).

  Next, the outcome when all reels 10a, 10b, and 10c are stopped is determined, and whether or not the JAC symbol (also used as “replay”) has stopped on the active line (step S407), or the small role symbol is valid It is determined whether or not the operation has stopped on the line (step S412).

  As a result of the determination, if it is not determined that either the JAC symbol or the small role symbol is stopped on the active line (No), the process proceeds to step S415, and the winning flag is turned OFF. In this case, it is considered that either the internal lottery was lost or the player could not arrange the small role symbols even if the small role winning flag was ON.

  On the other hand, if it is determined in step S407 that the small role symbol has stopped on the active line (Yes), the main control board 92 sends a drive signal instructing the payout of the number of medals corresponding to the small role to the hopper device. 78, and a payout sound command is transmitted to the sub-control board 94 (step S413). Further, when the main control board 92 instructs the payout, the payout counter is counted up by that number (step S414).

  Alternatively, when it is determined that the JAC symbol has stopped on the active line during the big bonus game (step S407 = Yes), the main control board 92 transmits a sound effect command to the sub-control board 94 (step S408). The RB / JAC game process (step S410) is performed at the same time, but no medals are paid out due to the JAC symbols being prepared. In the RB / JAC game game process, a game opportunity called a “JAC game” or a “regular bonus game” is given to the player. Further, when the JAC game processing is finished once, the JAC game counter is counted up there (step S411). The contents of the RB / JAC game are the same as the known “regular bonus game”.

  Similarly, when it is determined that the JAC symbol or the small role symbol has stopped on the active line, step S415 is executed subsequent to step S411 or step S414, respectively, and the winning flag is turned OFF there. Then, after each game end, it is determined whether or not the big bonus game itself should be ended (step S416), and while the end condition is not satisfied (No), the process returns to step S403 and the next start processing is performed. Done.

In general, a big bonus game ends when any of the following conditions is satisfied.
(1) The count of the small role game counter has reached 30 in step S406.
(2) The count number of the JAC game counter has reached 3 in step S411.
(3) The number of medals paid out has reached a predetermined number (for example, 450) determined in advance.

  If any of the above conditions is satisfied, the end determination in step S416 is affirmed (Yes), and then the big bonus game end processing is performed and the winning value table is restored (step S417).

(5-2. RB / JAC game processing)
FIG. 9 specifically shows the contents of the RB / JAC game processing. Here, first, initialization processing is performed, and the random value lottery value table is changed for the JAC game (step S501). In addition, the multiplier of medals is fixed to one. The winning value table changed here has more winning values for “JAC” as the winning type (special winning type) than usual, and the probability of winning the type “JAC” is higher. Yes (special winning probability change means).

  Next, start processing (step S502) and stop processing (step S503) of all reels 10a, 10b, and 10c are executed. When all the reels 10a, 10b, and 10c are stopped by the stop process, the symbol combination mode at that time, that is, the outcome (stop mode) is transmitted from the main control board 92 to the sub-control board 94 (step S504), and the JAC game counter Is counted up by one (step S505).

  Next, it is determined whether or not the JAC symbols have stopped on the effective line (in this case, the single line is limited to the middle line) when all the reels 10a, 10b, and 10c are stopped (step S506). As described above, the JAC symbol here is also used as “replay”, and the combination is often “replay-replay-replay”, but a combination of another symbol and “replay” symbol (for example, "7-replay-replay", "cherry-replay-replay", etc.) may be provided.

  If all the reels 10a, 10b, 10c are stopped and the JAC symbol is not stopped on the middle effective line (step S506 = No), the process proceeds to step S510 and the winning flag is turned OFF. In this case, it is considered that either the flag was not turned on simply because it was lost in the lottery, or the player missed the prize without being able to arrange the symbols even if the flag was turned on. However, in the case of winning, since the symbols are almost certainly aligned by the reel control, there is almost no loss here.

  Conversely, if it is determined that the JAC symbol has stopped on the active line (Yes), the main control board 92 drives the hopper device 78 to execute a specified number (for example, 15) of medals, and a payout sound. The command is transmitted to the sub control board 94 (step S508). When a payout is made, the payout counter is counted up by that number (step S509), and subsequently, the winning flag is turned off (step S510).

  Also in the RB / JAC game game process, one JAC game end determination (step S511) is performed. While the number of games paid out during the JAC game (winning number) has not yet reached a certain number (for example, 8 times), the end determination is denied (No), the process returns to step S502, and the JAC game is continued. The Thereafter, when the number of payouts (winning times) during the JAC game reaches a certain number (for example, 8 times), it is determined that one JAC game should be ended (Yes). In this case, the process proceeds to step S512 to finish the RB / JAC game, the winning value table is returned to the state before change (for the normal / small role game), and the big bonus game process (FIG. 8) is restored. .

(7. Details of power supply system)
Next, the configuration of the power supply system in the slot machine 1 of the present embodiment will be described in more detail.

  FIG. 10 shows a power supply system connected from the power supply unit 70 to the main control board 92 and the sub control board 94. When the rectifier circuit 70a generates DC24V (drive voltage power) and DC12V (control voltage power) operation power, the power supply unit 70 generates each operation power through the two power supply lines and the sub control circuit 92. Each is supplied to a substrate 94. Among them, the operating power of DC24V is for driving various loads (motors, LEDs, etc.) used for the progress of the game and various loads (speakers, lamps, liquid crystal display devices, etc.) used for presentation operations. . The CPUs 110 and 118 of the main control board 92 and the sub control board 94 output drive signals to the output transistors 142 and 150 to control driving of various loads. In FIG. 10, the reel drive motors 88a to 88c, the hopper device 78, the lockout solenoid 102, various lamps (LEDs), the liquid crystal display device 58, the speaker 56, etc. shown in FIG. It is written in. Further, the other components shown in FIG. 3 are omitted.

(7-1. Voltage converter)
The main control board 92 and the sub control board 94 are equipped with voltage converters 140 and 148 (three-terminal regulators), respectively, and the operating power of DC12V is controlled to 3.3V by the voltage converters 140 and 148, respectively. It is converted into electric power. The converted 3.3V control power is used to drive various electronic components (CPU, ROM, RAM, etc.) of the main control board 92 and the sub control board 94.

  The main control board 92 and the sub control board 94 are equipped with backup power supplies 144 and 152 (large capacity capacitors), respectively. These backup power supplies 144 and 152 continue to supply power for a considerable period (several days to several weeks) even after the power supply from the power supply unit 70 is cut off, and store the stored information in the RAMs 114 and 122. The power supply path between the voltage converters 140 and 148 and the backup power supplies 144 and 152 prevents the backflow of charges from the backup power supplies 144 and 152 when the operation of the power supply unit 70 is stopped (voltage drop). A diode is installed.

  As described above, in the present embodiment, the voltage converters 140 and 148 (three-terminal regulators) on the main control board 92 and the sub control board 94 are used by converting 12V operating power to 3.3V control power. Therefore, there are the following advantages.

  First, when the power supply unit 70 generates 3.3V (or 5V) control power and supplies it to the main control board 92 and the sub-control board 94, the necessary power supply due to the voltage drop of the power supply line. Voltage can be lost. Further, if the arrangement of the power supply unit 70 and various substrates in the main body 2 is different depending on the model of the slot machine 1, the length of the power supply line is also different according to the arrangement. For this reason, there arises a problem that the voltage of the control power actually supplied varies depending on the model.

  On the other hand, if the control power (3.3 V) required for the voltage converters 140 and 148 (three-terminal regulator) on each substrate is generated as in this embodiment, the voltage of 12 V operating power is Even if it changes, the output voltage of the 3-terminal regulator is stable, so that it is possible to stably supply the control power necessary for various electronic components, effectively eliminating the influence of the voltage drop on the power line. be able to.

  Moreover, even if the wiring length of the power supply line for supplying 12V operating power differs depending on the model, 3.3V control power can be generated in each board. Regardless, there is an advantage that stable control power at a constant voltage can be supplied to various electronic components.

  Furthermore, even when noise intervenes in the 12V power line, which is a relatively high voltage, the influence of the noise is relatively reduced by the three-terminal regulator, resulting in the noise applied to various electronic components. The influence can be reduced.

(7-2. Power supply monitoring IC)
The power supply unit 70 is equipped with a power supply monitoring IC 116 (power supply monitoring means), and this power supply monitoring IC 116 has a function of individually monitoring the output voltage of the operating power (+ 24V, + 12V) supplied from the power supply unit 70. Have. For example, when the output voltage of 24V operating power or 12V operating power is decreased (for example, decreased to 90% or less) by the operation of turning off the power switch 76, the power monitoring IC 116 individually detects a decrease in each operating power. When power supply monitoring IC 116 detects a drop in the output voltage of 24V operating power or 12V operating power, it individually outputs a power failure signal (24V power failure warning signal or 12V power failure warning signal).

  The 24V power failure warning signal and the 12V power failure warning signal are distributed to the main control board 92 and the sub control board 94, respectively. Among them, in the main control board 92, the 24V power failure warning signal and the 12V power failure warning signal are input to the logic operation circuit 146 (here, the OR circuit), and the output signal of the logic operation circuit 146 is the INT terminal 110b (interrupt terminal) of the CPU 110. ). On the other hand, in the sub control board 94, the 24V power failure warning signal is input to the input port 118a of the CPU 118, and the 12V power failure warning signal is input to the INT terminal 118b. The INT terminals 110b and 118b are for generating external interrupts (maskable interrupts). When the input voltage of the INT terminals 110b and 118b is switched from a high level to a low level, the CPUs 110 and 118 Transitions to a state where interrupt processing is executed and interrupt processing at power failure is executed (power failure processing state transition means, special power failure processing state transition means).

(Auxiliary power supply means)
The power supply unit 70 has a built-in capacitor, and necessary operating power is supplied from the capacitor to the CPUs 110 and 118 even after the power switch 76 is turned off and a power failure warning signal is output. The capacitor has a sufficient capacity so that the power supply can be maintained during the period required for each CPU 110, 118 to execute the interruption process at the time of power failure. Even if the capacitance of the capacitor further decreases, the necessary power is compensated by the backup power supplies 144 and 152 installed on the main control board 92 and the sub control board 94, respectively.

  When the interruption processing at power failure is executed in each of the CPUs 110 and 118, the information of the current setting values (any one of 1 to 6) stored in the RAMs 114 and 122 until then is the backup power supply 144, as it is even after the power is cut off. 152 is stored as it is. Therefore, normally, when the power switch 76 is shut off (power OFF) under the management of the game hall operator, the RAM 114 is activated when the CPU 110 of the main control board 92 and the CPU 118 of the sub control board 94 are activated by the next power-on. , 122 are used as the current setting values as they are. The setting value can be changed (setting change) by using a dedicated setting change key when the power is turned on under the management of the game hall operator. The setting change process of the slot machine 1 will be described below.

(8. Setting change process)
FIG. 11 specifically shows setting change processing executed by the CPU 110 of the main control board 92. When a dedicated key is inserted into the setting key switch 72 of the power supply unit 70 and is turned clockwise, the power switch 76 is turned on, and the CPU 110 of the main control board 92 shifts to a state in which setting change processing is executed. . Note that the RAM 114 is checked before the setting change process when the power is turned on, which will be described later together with the power-on process.

  In the setting change process, first, the CPU 110 sets the interrupt permission in order to process the display function and the communication function by the scheduled interrupt (step S6001), and then executes the set value confirmation process (step S6002). In the set value confirmation processing, the CPU 110 refers to the set value data stored in the RAM 114 as the current set value. Next, the CPU 110 sets a setting value change start command (step S6004). As a result, the CPU 110 enters a setting change mode.

  Although not shown in FIG. 11, during the execution of the setting change process, the CPU 110 displays the setting value that is currently set or the setting value that is a candidate after the change as a setting value display unit (also used as the credit number display unit 30). ) To display numerical values (set value display means). Thereby, the person in charge of a game hall can confirm the present condition or the setting value after a change visually.

  In the next step S6006, the CPU 110 determines whether or not the rotating cylinder rotation starting device has been turned on (whether the starting lever 18 has been operated). Normally, when the start lever 18 is operated in the setting change operation, the set value is determined. However, since the start lever 18 is not operated before the changed set value is determined (step S6006 = NO), the CPU 110 next proceeds to step S6008. move on.

  In step S6008, the CPU 110 determines whether or not the setting switch (also used as the reset switch 74) is turned on. When the ON signal of the setting switch is input to CPU 110 (step S6008 = YES), CPU 110 adds 1 to the current setting value data (step S6010). As a result, the current setting value is changed to a setting value that is one step higher (setting value candidate switching means). At this time, if the set value is in an indeterminate state due to destruction or loss of stored information in the RAM 114, 1 is set as the set value.

  Further, when 1 is added to the set value data, the CPU 110 determines whether or not the set value data is 7 or more (step S6012). In the present embodiment, since the range of the preset setting value is 1 to 6, when the setting value data is 7 or more (step S6012 = YES), the CPU 110 sets the setting value to 1 (step S6014). ). On the other hand, if the set value data is not 7 or more (step S6012 = NO), only 1 is added to the current set value data. As a result, the set value data increases from 1 to 6 in order and returns to 1 after 6 (1 → 2 → 3 → 4 → 5 → 6 → 1). During this time, the set value data is numerically displayed on the set value display section as a set value that becomes a candidate after the change.

  In any case, when the set value data is changed by the ON signal of the setting switch, the CPU 110 sets a set value command based on the changed set value data (step S6016), and then returns to step S6006 to rotate the rotating cylinder. It is determined whether or not the starting device has been turned on (whether or not the starting lever 18 has been operated).

  When CPU 110 detects that the rotating cylinder rotation starting device has been turned on (step S6006 = YES), it next sets a set value change end command (step S6018). As a result, the set value set as the candidate after change is confirmed as the set value that is actually set, and thereafter, the set value data in the RAM 114 is rewritten with the changed content (change confirmation means).

  Thereafter, the CPU 110 waits until the setting key switch 72 is turned off (step S6020). When the setting key switch 72 is actually switched off (step S6020 = YES), the setting change process is returned. .

(9. Countermeasures for unauthorized setting changes)
The above is the processing when the set value is regularly changed (setting change) under the management of the game hall operator. In addition, in the present embodiment, the setting change (setting change goto) is performed by cheating. In the event of a break, measures are taken to make this known to the surroundings.

  For example, the setting is changed by improper action. For example, a metal piece is inserted into the main body 2 and the power line or connector is short-circuited to forcibly cut off and turn on the power. It is executed by bringing a metal piece into contact with the connector terminal. If the CPU 110 of the main control board 92 executes the setting change process due to such an illegal act, the setting value is changed as the fraudster thinks against the intention of the game hall operator.

  Therefore, in the present embodiment, as described above, the power supply line connected from the power supply unit 70 to the main control board 92 and the sub control board 94 is composed of two systems of the 24V system and the 12V system, and the main control board 92 and the sub control board are further configured. The CPUs 110 and 118 of 94 can execute the following processing to make it aware that there has been an illegal act.

(9-1. Interrupt generation conditions at power failure)
As is apparent from the configuration of the power supply system shown in FIG. 10, in this embodiment, the CPU 110 of the main control board 92 and the CPU 118 of the sub control board 94 have different conditions for generating a power failure interrupt. That is, the CPU 118 of the main control board 92 generates a power failure interrupt by the OR condition (logical sum) of the output of the 24V power failure warning signal and the output of the 12V power failure warning signal. On the other hand, the CPU 118 of the sub-control board 94 generates a power failure interrupt only on the condition that the 12V power failure warning signal is output.

(9-2. Main control board interrupt processing at power failure)
FIG. 12 shows the contents of the interruption processing at the time of power failure executed by the CPU 110 of the main control board 92. As described above, when any one of the 24V power failure warning signal or the 12V power failure warning signal is output, the CPU 110 shifts to a state in which the interruption processing at power failure is executed. In this interruption processing at power failure, the CPU 110 first saves the contents of various registers in the register save area of the RAM 114 (step S2004), and similarly saves the stack pointer (step S2006). In the power-on process executed by the next power-on, the register contents are restored based on the saved contents.

  Next, the CPU 110 performs output port clear processing, thereby turning off each output port (step S2008). As a result, the progress of the game does not change after the interruption of the power failure signal.

  The CPU 110 sets check data in the RAM 114 (step S2010) and creates sum data from the stored information in the RAM 114 (step S2012). That is, the CPU 110 sets the calculation start address of the backup area of the RAM 114, which is the checksum calculation target, to the pointer, and also sets the checksum calculation count. Then, the CPU 110 sequentially adds the value of the backup area sequentially designated by the pointer to the value of the checksum data area (exclusive OR), and sequentially updates the calculation result to the checksum data area. Calculate the checksum. The sum data created in this way is used for the sum check in the next power-on process.

  Thereafter, the CPU 110 sets an access prohibition value in the access register of the RAM 114 and prohibits access to the RAM 114 (step S2014). Next, the CPU 110 executes a HALT instruction (step S2016) and enters a standby state.

(9-3. Interrupt processing at power failure of sub control board)
Next, FIG. 13 shows the contents of the interruption processing at the time of power failure executed by the CPU 118 of the sub control board 94. Regarding the CPU 118 of the sub control board 94, when the interrupt generation condition is satisfied by the output of the 12V power failure warning signal, the CPU 118 interrupts the effect processing so far and shifts to a state of executing the power failure interrupt processing of FIG.

  In this interruption processing at power failure, the CPU 118 first sets a 24V power failure signal timer (step S3001). The timer set here may be a time of about 33 ms (for two cycles of 60 Hz), for example. Next, the CPU 118 executes a 24V power failure signal input process (step S3004) until the 24V power failure signal timer expires (step S3002 = NO). In the 24V power failure signal input process (step S3004), the CPU 118 refers to the input port 118a and confirms the input of the 24V power failure warning signal. Under normal specifications, when the power is shut down (OFF operation of the power switch 76), the 24V power supply is reduced first. Therefore, when the power is shut off normally, the CPU 118 uses the 24V power failure warning signal already input here. Can be confirmed.

  When the timer expires (step S3002 = YES), the CPU 118 determines whether or not a 24V power failure warning signal is input during the timer count (step S3006). If the 24V power failure warning signal is not inputted at this time (NO), the CPU 118 stores the fact that the 24V power failure warning signal has not been inputted (represented by ON of the dedicated flag in the process) in the RAM 122 (step) S3008). Conversely, if a 24V power failure warning signal is input at this time (step S3006 = YES), the CPU 118 proceeds to the next step S3010 as it is (without turning on the dedicated flag).

  In any case, the CPU 118 of the sub-control board 94 confirms whether or not the 24V power failure warning signal is input over a certain time lag (predetermined period) after the 12V power failure warning signal is output (steps S3002 and S3004). The presence / absence of input is recorded in the RAM 122.

  The subsequent procedure is the same as in the case of the main control board 92, and the CPU 118 saves the contents of various registers in the register save area of the RAM 122 (step S3010), and also saves the stack pointer (step S3012). Also in the CPU 118 of the sub-control board 94, in the power-on process executed by the next power-on, the register contents are restored based on the saved contents.

  Next, the CPU 118 performs output port clear processing, thereby turning off each output port (step S3014). As a result, various performance operations (sound output, lamp lighting, image display, etc.) performed after the interruption of the power failure signal are stopped.

  The CPU 118 sets check data in the RAM 122 (step S3016), and creates sum data from the stored contents of the RAM 122 (step S3018). The created sum data is used for sum check in the next power-on process. used.

  Similarly, after this, the CPU 118 sets an access prohibition value in the access register of the RAM 122 and prohibits access to the RAM 122 (step S3020). Next, the CPU 118 executes HALT (step S3022) and enters a standby state.

(9-4. Grounds for fraud detection)
The grounds for detecting fraud in this embodiment are as follows.
That is, even when a 12V power supply line is shorted by inserting a metal piece into the main body 2 and a 12V power failure warning signal is thereby output, the two power supply lines are simultaneously shorted by an illegal act. Since it is extremely difficult to do so, a 24V power failure warning signal is not output from the power supply monitoring IC 116 unless the 24V system power supply lines are simultaneously shorted. However, if a 12V power failure warning signal is output, the interrupt generation condition is satisfied for both the CPU 110 of the main control board 92 and the CPU 118 of the sub control board 94 by itself. Will be.

  In this case, even if the interrupt generation condition is satisfied, the CPU 118 of the sub control board 94 cannot confirm the output of the 24V power failure warning signal until the 24V power failure signal confirmation timer counts up (in FIG. 13). In step S3006 = NO), the RAM 122 of the sub-control board 94 is backed up with the fact that the 24V power failure warning signal has not been input together with the current set value information (step S3008 in FIG. 13).

  Thereafter, when the setting value is changed on the main control board 92, a setting value signal representing the changed setting value is transmitted from the main control board 92 to the sub control board 94. If the fact that the 24V power failure warning signal was not input in the previous power failure interrupt process is backed up, the CPU 118 can determine that the setting value change made this time is due to an illegal act. This is because when a normal setting change operation is performed, a 24V power failure warning signal should be output together with a 12V power failure warning signal when the power is turned off. This is because there is a high probability that the 12V system power line is short-circuited due to fraud.

  In the present embodiment, the following logic is adopted in the power-on process executed by the CPU 110 of the main control board 92 and the CPU 118 of the sub-control board 94 based on the grounds for unauthorized detection as described above.

(9-5. Main control board power-on processing)
First, FIG. 14 and FIG. 15 show a power-on process executed by the CPU 110 of the main control board 92. Normally, the CPU 110 executes power-on processing when the power switch 76 is turned on. However, when an illegal act is performed, the voltage of the power line (12V system) returns to normal due to removal of a metal piece or the like. Sometimes, the CPU 110 executes power-on processing.

  In the power-on process, first, various switch signals are input by referring to the input port of the CPU 110 (step S1002). The switch signal input here includes an ON / OFF signal of a stop mode switching switch and an automatic settlement mode switching switch installed in the slot machine 1. These change-over switches are installed on, for example, the power supply unit 70 (or the back side of the front door 4), and the game machine operator switches each switch to ON or OFF in advance, thereby stopping the slot machine 1. It is possible to select whether to enter the mode or whether to enter the automatic checkout mode. If the slot machine 1 is in the stop mode (stop mode switching switch is ON), the main control board 92 puts the slot machine 1 in the game end state when one big bonus game ends, and the subsequent games Executes control to stop execution. If the slot machine 1 is in the automatic settlement mode (the automatic settlement switch is ON), the main control board 92 settles the credit every time one big bonus game is finished, and medals for the number of stored credits. Execute the control to pay out.

  In step S1006, the CPU 110 initializes a built-in register. Subsequently, the CPU 110 determines whether or not the check data (prefixed value) in the RAM 114 is normal (step S1008). This is because the check data of the fixed value is checked separately from the sum data, so that the sum data may coincide even if the contents of the RAM 114 are destroyed. is there. If the check data is normal (YES), the CPU 110 next determines whether the sum data is normal (step S1010). At this time, the CPU 110 sets the calculation start address of the backup area of the RAM 114, which is the checksum calculation target, to the pointer, and also sets the number of checksum calculations. Then, the CPU 110 sequentially adds the value of the backup area sequentially designated by the pointer to the value of the checksum data area (exclusive OR), and sequentially updates the calculation result to the checksum data area. Calculate the checksum.

  Normally, the checksum data calculated in the previous power failure process (when the power is turned off) is stored as it is in the backup area of the RAM 114, and thus is stored in the backup area and the checksum data calculated this time. The checksum data matches each other. As described above, when the CPU 110 determines that the checksum data is normal in step S1010 (YES), it stores the switch signal input data in the RAM 114 (step S1012), and then sets the key switch for setting (setting key). It is determined whether or not the switch 72) is ON (step S1014).

  In particular, when the setting change operation is not performed or when there is no fraud, since the setting key switch 72 is normally in an OFF state (step S1014 = NO), the CPU 110 is currently backed up in the RAM 114. Is transmitted to the sub-control board 94 (step S1015).

  Thereafter, the CPU 110 sequentially executes the remaining steps S1016 to S1028 of the power-on process. That is, the CPU 110 clears unused areas in the stack area of the RAM 114 (step S1016), and then restores the output port when the power is turned off (step S1018). As a result, the output port that was in the output state when the power was turned off returns to the original output state. Note that the output port to be restored is backed up in the RAM 114 at the previous power-off.

  Subsequently, the CPU 110 clears the check data and the sum data in the RAM 114 (steps S1020 and S1022). When the CPU 110 sets the input port data at the previous power-off (step S1024), the CPU 110 sets the stack pointer at the previous power-off (step S1026), and saves it in the backup area at the previous power-off. The contents of the register are restored based on the stored data (step S1028). Through the above procedure, the CPU 110 returns to the power-on process when the state at the previous power-off is recovered.

  As described above, when the check data and the sum data stored in the backup area of the RAM 114 are normal when the power is turned on (steps S1006 and S1008 = YES), and the setting change operation is not performed (step S1012 = NO). ), The CPU 110 can continue to control the progress of the game from the previous power-off state.

  On the other hand, when the regular setting change is performed or when the setting key switch 72 is turned ON by an illegal action (step S1014 = YES), the CPU 110 proceeds to step S1036 in FIG. A setting change process is executed (connection symbol 2 → 2). The setting change process is the same as that already described.

  When the CPU 110 finishes the setting change process (step S1036), the CPU 110 transmits a setting value signal representing the changed setting value to the sub-control board 94 (step S1037). Next, the CPU 110 clears the memory other than the set value data and the changeover switch data stored in the RAM 114 (step S1038). Further, the CPU 110 clears the stack area of the RAM 114 (step S1040) and initializes the external output (step S1042).

  After the above procedure, the CPU 110 shifts to the main loop (steps S1044 to S1054. At this time, the CPU 110 performs step S1042 for each game regardless of whether it is in the normal gaming state or the special gaming state. To step S1050, that is, the CPU 110 clears the use area of the RAM 114 for each game (one game) (step S1044), and then performs a spinning game process (step S1046). Is the same as shown in FIG.

  CPU110 will perform a game flag determination, if a spinning game process (step S1046) is complete | finished (step S1048, S1050). As a result of the game flag determination, if the big bonus game end flag is not ON (step S1050 = NO), the CPU 110 returns to step S1044 and executes the main loop in the next game.

  The above is a flow in the normal gaming state, but once a transition is made to a big bonus game, the end flag is turned ON in the end processing of the big bonus game (step S417 in FIG. 8) (step S1050 = YES). In this case, the CPU 110 executes stop and checkout processing (step S1052), and clears the use area of the RAM 114 every time the big bonus game ends (step S1054).

  When the check data or the sum data stored in the backup area of the RAM 114 is not normal when the power is turned on (step S1008 or S1010 = NO), the CPU 110 processes the error display function and the communication function with a scheduled interrupt. (Step S1029), the process proceeds to step S1030, and the changeover switch data is stored in the RAM 114. When the CPU 110 displays an error code (“S0” or the like) indicating that the set value is indeterminate in the error display section (also used as the payout number display section 34) (step S1032), the setting key switch 72 (step S1034 = NO).

  After that, when the setting key switch 72 is properly switched to the ON position by the game hall manager (step S1034 = YES), the CPU 110 proceeds to step S1036 and executes the setting change process. When the setting value is set to any one of 1 to 6 in this setting change processing, the setting value data stored in the RAM 114 (setting storage unit) is in an unconfirmed state (data has been destroyed). State) to regular data corresponding to any of the setting values 1 to 6. When the error is canceled by the setting change operation, the CPU 110 clears the display of the setting unconfirmed error.

  As described above, when a problem is found in the check data or the sum data of the RAM 114 in the power-on process, the CPU 110 displays a setting unconfirmed error and shifts to the standby state of the setting key switch 72 (change operation request means In addition, the game can be disabled (game progress stopping means). In addition, the CPU 110 continues to loop the standby state of the setting key switch 72, and once the execution of the game is disabled, the setting value is normally set (changed) through the setting change process (step S1036). It is possible to permit the progress of the game to be resumed only (game progress permission means). Thereby, the CPU 110 can exclude the setting value from being changed or newly set without being based on the setting changing operation.

(9-6. Sub-control board power-on processing)
Next, FIG. 16 to FIG. 18 show power-on processing executed by the CPU 118 of the sub control board 94. The detection of fraud based on the above logic is performed in this power-on process.

  The CPU 118 of the sub-control board 94 also executes a power-on process when the power switch 76 is turned on. However, when an illegal act is performed, the voltage of the power line (12V system) is removed by removing a metal piece or the like. When the CPU returns to normal, the CPU 118 executes the power-on process.

  In this power-on process, first, the CPU 118 initializes a built-in register (step S4006), and then determines whether the check data (fixed value) and the sum data in the RAM 122 are normal (step S4008, step S4008). S4010). If the check data and the sum data are both normal (YES), then the CPU 118 clears the unused area of the stack area (step S4012), and restores the output port when the power is turned off (step S4014). Then, the CPU 118 clears the check data and the sum data of the RAM 122 (steps S4016 and S4018), sets the input port data at the previous power-off (step S4020), and sets the stack pointer at the previous power-off (step S4020). In step S4022), the contents of the register are restored based on the data saved in the backup area at the previous power-off (step S4024). After the above procedure, the CPU 118 returns to the state at the previous power-off, and then proceeds to step S4036 in FIG. 17 (connection symbol 4 → 4).

  When the initialization processing is performed in step S4036, the CPU 118 waits for input of a setting value signal transmitted from the main control board 92 (step S4038). The set value signal waiting here is transmitted when the CPU 118 of the main control board 92 executes the power-on process (step S1015 in FIG. 14 or step S1037 in FIG. 15).

  When a setting value signal is input from the main control board 92 (step S4038 = YES), the CPU 118 compares the setting value received this time with the previous setting value stored in the RAM 122, and the setting value from the previous power failure. It is determined whether or not has been changed (step S4040). As a result, if the set value has not been changed since the previous time (NO), the CPU 118 returns to the power-on process. Such a procedure is performed when the power is normally turned on again without any setting change operation.

  On the other hand, when CPU 118 determines that the set value has been changed since the previous power failure (step S4040 = YES), the fact that the 24V power failure warning signal was not input at the previous power failure (dedicated flag is ON) is stored in RAM 122. It is determined whether or not (step S4042). In particular, if such a fact is not stored (NO), the CPU 118 stores the setting value received this time in the RAM 122 (step S4046), and returns the power-on process. Such a procedure is performed when a setting change operation is normally performed.

  On the other hand, when the setting is changed illegally due to a short circuit of the power line of the 12V system, the fact that the 24V power failure warning signal has not been input at the previous power failure is stored in the RAM 122. In this case, both of the two conditions that the setting value has been changed since the previous power failure and that no 24V power failure warning signal was input at the previous power failure are satisfied (step S4040 = YES and step S4042). = YES), the CPU 118 executes the fraud detection process (step S4044) based on the basis of the above-described fraud detection (the previous power failure is not normal and the set value is different from the previous time when the power is turned on). As a result, a process of notifying the surroundings (including not only other players, hall employees, security guards, but also mechanical equipment such as hall computers) is performed.

  In the fraud detection process (step S <b> 4044), the CPU 118 outputs a fraud sound from the speaker 56 at a high volume, or outputs a voice such as “It is a fraudulent act!” Character information such as “There was an illegal act!” Is displayed, or the lamps 60, 62, and 64 are flashed violently. As a result, a warning can be issued for fraudulent acts, and it is possible to clearly tell (or notify, appeal) that fraud has been made in the surrounding area, so it is easy to identify fraudsters on site. can do.

  Alternatively, without revealing the above-mentioned appealing operation, an illegal detection signal is output from the sub-control board 94 to the hall computer 108 through the external terminal board 96, and it is a secret that an illegal act has been performed by the game hall manager. You can also report to. In this case, since the manager of the game arcade can hold the spot while the game continues with a face that the cheating person does not eat, it is possible to strictly cope with the cheating person.

  The fraud detection process (step S <b> 4044) is returned when the person in charge of the game hall performs an error canceling operation using the dedicated key or opens the front door 4 and operates the reset switch 74. In this case, the CPU 118 clears the fact that the 24V power failure warning signal was not inputted at the time of the previous power failure in step S4045 (dedicated flag is turned OFF), and returns the processing at power-on.

  By executing the above processing by the CPU 118, even if the setting change operation is performed by an illegal act in the slot machine 1 of the present embodiment, the illegal act can be reliably detected. For this reason, it is possible to reliably prevent the game from being played with the set value changed against the intention of the game hall operator. Further, in the slot machine 1 of the present embodiment, it is impossible to conceal fraud aimed at changing settings, and the deterrence of fraud is increased due to its difficulty.

  If the check data or the sum data stored in the backup area of the RAM 122 is not normal when the power is turned on (step S4008 or S4010 = NO), the CPU 118 proceeds to step S4026 in FIG. 18 and clears the stack area. (Step S4026) and the external output is initialized (Step S4028). Then, CPU 118 waits for input of a set value signal transmitted from main control board 92 (step S4030 = NO). When a set value signal is transmitted from the main control board 92 (YES), the CPU 118 stores the received set value in the RAM 122 (step S4032), and executes an effect process (step S4034) as the game progresses.

(10. Production process)
FIG. 19 shows the contents of the effect process executed by the CPU 118 of the sub control board 94. In this effect process, first, the CPU 118 performs an initialization process (step S801). Next, the CPU 118 waits for a medal insertion command transmitted from the main control board 92, and when the medal insertion command is actually transmitted, the CPU 118 executes an effect of outputting an insertion sound, a bet sound, and the like (step). S802).

  Subsequently, the CPU 118 waits for a winning (starting) flag command transmitted from the main control board 92 (step S803). The winning (starting) flag command is transmitted from the main control board 92 in response to the operation of the starting lever 18, and upon receiving the winning (starting) flag command, the CPU 118 controls the rendering operation in accordance with the winning (starting) flag command. The effect operation here is, for example, an output of a reel start sound, an image display effect by the liquid crystal display device 58, or the like.

  When the start effect is performed, the CPU 118 then waits for first to third stop information commands (steps S804 to S806). When the three stop buttons 20, 22, 24 are operated in an appropriate order, the first to third stop information commands are sequentially transmitted from the main control board 92 to the sub control board 94, and in response to this, the sub control board 94 The CPU 118 controls the rendering operation according to the winning flag and the first to third stop information commands, respectively. The effect operation here includes, for example, output of each reel stop sound, reel light extinction effect, image display effect by the liquid crystal display device 58, and the like. In particular, when receiving the third stop information command, the CPU 118 executes an effect operation according to the winning type at that time (step S806).

  Then, since a payout command is transmitted from the main control board 92 according to the result of the determination processing, the CPU 118 receives this and executes the effect by the payout sound output (step S807). Further, the CPU 118 waits for a game status command transmitted from the main control board 92 and examines the current game status from the received command. The game status represents, for example, “Big Bonus Game”, “RB / JAC Game”, “Bonus Game End”, or the like.

(11. Second embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, the schematic configuration (FIGS. 1 and 2), control configuration (FIG. 3), game flow (FIGS. 4 to 9), and setting change processing (FIG. 11) are common to the first embodiment. Description of these common parts is omitted. In addition, the same code | symbol is attached | subjected about a common structure (a member and the step in a flowchart are included) by 1st Embodiment and 2nd Embodiment.

  In the first embodiment described above, whether or not the unauthorized detection processing should be performed is determined by the cooperation of the main control board 92 and the sub control board 94. However, in the second embodiment, the unauthorized detection is performed by the main control board 92 alone. Processing can be determined, and the sub-control board 94 executes fraud detection processing based on the determination result of the main control board 92.

  FIG. 20 shows a configuration applicable to the second embodiment. Here, differences from the first embodiment (FIG. 10) will be particularly described, and the same reference numerals as those in the first embodiment are given to common configurations.

  In the case of the second embodiment, the CPU 110 of the main control board 92 is configured to receive the 12V power failure warning signal at the INT terminal 110b and the 24V power failure warning signal at the input port 110a. Therefore, when a 12V power failure notice signal is output from the power supply monitoring IC 116, the CPU 110 enters a state in which a power failure interruption process is executed in preference to the previous periodic processing (power failure processing state transition means).

(11-1. Interrupt processing at power failure)
The contents of the interruption processing at the time of power failure executed by the CPU 110 of the main control board 92 in the second embodiment can be described with reference to the flowchart of FIG. The flowchart of FIG. 13 shows the interruption processing at power failure executed by the CPU 118 of the sub control board 94 in the first embodiment. This flowchart is directly executed by the CPU 110 of the main control board 92 in the second embodiment. Applicable to interruption processing at power failure.

  That is, when the CPU 110 of the main control board 92 executes the interruption process at the time of power failure, first, a 24V power failure signal timer is set (step S3001). The timer set here may be a time of about 33 ms (for two periods of 60 Hz) as described in the first embodiment. Next, the CPU 110 executes a 24V power failure signal input process (step S3004) until the 24V power failure signal timer expires (step S3002 = NO). In this 24V power failure signal input process (step S3004), the CPU 110 refers to the input port 110a and confirms the input of the 24V power failure warning signal. Under normal specifications, when the power is shut off (OFF operation of the power switch 76), the 24V power supply decreases first. Therefore, when the power is shut off normally, the CPU 110 uses the 24V power failure warning signal already input here. Can be confirmed.

  When the timer expires (step S3002 = YES), CPU 110 determines whether or not a 24V power failure warning signal is input during the timer count (step S3006). If the 24V power failure warning signal is not input at this time (NO), the CPU 110 stores in the RAM 114 the fact that the 24V power failure notification signal has not been input (represented by the ON of the dedicated flag in the process) (step). S3008). Conversely, if a 24V power failure warning signal is input at this time (step S3006 = YES), the CPU 110 proceeds to the next step S3010 as it is (without turning on the dedicated flag).

  In any case, the CPU 110 of the sub control board 94 confirms whether or not the 24V power failure warning signal is input over a certain time lag (predetermined period) after the 12V power failure warning signal is output (steps S3002 and S3004). The presence / absence of input is recorded in the RAM 114.

  Thereafter, as in the first embodiment, the CPU 110 saves the contents of various registers in the register save area of the RAM 114 (step S3010), and also saves the stack pointer (step S3012). Next, the CPU 110 performs output port clear processing, thereby turning off each output port (step S3014). The CPU 110 sets check data in the RAM 114 (step S3016), and creates sum data from the stored information in the RAM 114 (step S3018). Thereafter, the CPU 110 sets an access prohibition value in the access register of the RAM 114 and prohibits access to the RAM 114 (step S3020). Next, the CPU 110 executes a HALT instruction (step S3022) and enters a standby state.

(11-2. Processing at power-on)
21 to 23 show the power-on process executed by the CPU 110 of the main control board 92 in the second embodiment. As in the first embodiment, the CPU 110 normally executes power-on processing when the power switch 76 is turned on. However, when an illegal act is performed, the power line (12V system) is removed by removing a metal piece or the like. When the voltage of) returns to normal, the CPU 110 executes power-on processing. Here, a description will be given by citing differences from the case of the first embodiment in particular, and description of common contents will be omitted.

  Since the contents of each step shown in FIGS. 21 and 23 are all the same as those in the first embodiment, a duplicate description is omitted here, and steps S5000 to 5006 unique to the second embodiment are described in FIG. . In the power-on process of the second embodiment, when the CPU 110 finishes the setting change process (step S1036), the CPU 110 next determines whether or not the setting value has been changed since the previous power failure (step S5000). If the setting value has been changed since the previous power failure through the setting change process (step S1036) (step S5000 = YES), then the fact that the 24V power failure warning signal was not input at the previous power failure (dedicated It is determined whether or not “flag is ON” is stored in the RAM 114 (step S5002). If such a fact is not stored (NO), the CPU 110 proceeds to step S1037 in FIG. 23 and continues the same processing as in the first embodiment (connection symbol 7 → 7). Such a procedure is performed when a setting change operation is regularly performed by the game hall manager.

  On the other hand, if a setting change is made illegally as a result of an unauthorized power failure caused by a 12V power line short circuit and the operation of the setting key switch 72 or reset switch 74 due to an unauthorized act, the previous power failure The fact that the 24V power failure warning signal was not input at times is stored in the RAM 114. In this case, both of the two conditions that the setting value has been changed since the previous power failure and that the 24V power failure warning signal was not input at the previous power failure are satisfied (step S5000 = YES and step S5002). = YES), based on the basis of the fraud detection described in the first embodiment (the previous power failure is not normal and the setting value is different from the previous time when the power is turned on), the CPU 110 changes to the sub-control board 94. An unauthorized detection signal is transmitted (step S5004). The fraud detection signal is a command for causing the sub-control board 94 to execute fraud detection processing. Upon receiving this fraud detection signal, the sub-control board 94 performs the fraud detection process (steps described in the first embodiment). The processing having the same contents as in S4044) is executed. As a result, in the second embodiment, the fact that fraud has been carried out (including not only other players, hall employees, security guards and other personnel but also machine equipment such as hall computers) is to be detected. Can do.

  In addition, when the CPU 110 of the main control board 92 transmits the fraud detection signal, the error display unit 34 loops step S5006 for displaying an error code (“S0” or the like) to enter an error state (game progress stopping means). As a result, it is possible to prevent a situation in which the game proceeds with an unauthorized setting change.

(11-3. Error cancellation / normal recovery)
When a fraud detection process is performed in the second embodiment, when an employee or responsible person of a game hall who notices an alarm sound or the like cuts off the power of the slot machine 1 (power switch 76 is turned OFF), an alarm sound is generated there. Etc. are stopped, and the error state is released. After that, when the game hall administrator turns on the power switch 76 again and performs a normal setting change operation to restore the original intended setting value, the power switch 76 is normally turned off at the previous power failure. Therefore, the fact that the 24V power failure warning signal was not input at the time of the previous power failure is not stored in the RAM 114 of the main control board 92. In this case, CPU 110 determines in step S5002 that the input of the 24V power failure warning signal has been confirmed at the previous power failure (NO), and proceeds to step S1037 in FIG. 23 to continue normal processing.

(12. Other forms)
The present invention is not limited to the first and second embodiments described above, and can be implemented with various modifications.

  In the first and second embodiments, the power supply monitoring IC 116 is built in the power supply unit 70, but a power supply monitoring unit including the power supply monitoring IC may be provided separately. Alternatively, a power supply monitoring IC is mounted on the main control board 92 to generate a 12V power failure warning signal and a 24V power failure warning signal, and the power failure warning signal is transmitted from the main control board 92 to the sub control board 94. May be.

  In the interruption process at the time of power failure in FIG. 13, when the CPU 118 (CPU 110 in the second embodiment) determines in step S3006 that a 24V power failure warning signal has been input (YES), the fact that a 24V power failure warning signal has been input is indicated. There may be a step of saving in the register area. In this case, the interruption processing at the time of power failure confirms whether or not the 24V power failure warning signal is input during the timer count, and as a result, indicates whether or not the 24V power failure notification signal is input (or the output from the power supply monitoring IC 116). It becomes the composition to preserve.

  Alternatively, in the interruption process at power failure in FIG. 13 (common to both the first and second embodiments), the same determination procedure as that in step S3006 is added after step S3004, and the input of the 24V power failure warning signal is not confirmed here. (NO), the CPU returns to step S3002 and continues to monitor the 24V power failure warning signal, but if it is determined that a 24V power failure warning signal has been input in this determination procedure (YES), the CPU determines that the timer time is up. You may transfer to step S3010 without going through (step S3002).

  Further, in the interruption process at power failure in FIG. 13 (common to both the first and second embodiments), the CPU first executes the procedure of step S3010 to step S3018 and then executes the procedure of step S3001 to step S3008. It may be. Even in this case, the same determination procedure as in step S3006 is added after step S3004 as described above. If the input of the 24V power failure warning signal is not confirmed (NO), the CPU returns to step S3002. The 24V power failure warning signal is continuously monitored. If it is determined that the 24V power failure warning signal has been input in this determination procedure (YES), the CPU proceeds to step S3010 without going through the timer time-up determination (step S3002). You may migrate.

  In the first and second embodiments, in the power-on processing of the sub control board 94 or the main control board 92, the set value is changed from the previous power failure, and no 24V power failure warning signal is input at the previous power failure. It is configured to execute the fraud detection process on the condition that it has been, but if the 24V power outage warning signal was not input at the time of the previous power outage, any alarm will be output when the power is turned on this time Alternatively, an error state may be generated. That is, the fact that the 24V power failure warning signal was not output from the power supply monitoring IC 116 at the time of the previous power failure means that there is a high probability that the previous power failure was caused by an unauthorized act (short-circuit of the 12V system power line due to a metal piece, etc.). . In this case, although the fraudster has failed in the setting change operation, it is possible to detect the possibility that the power line has been short-circuited in order to attempt fraud, so an alarm or an error condition is generated at that time. This will prevent unauthorized setting changes.

  In addition, the configuration of the slot machine described in the first and second embodiments is a preferable example, and it goes without saying that various modifications and additions are possible.
