Description

  The present invention relates to a gaming machine that can transmit information to other gaming machines by sound.

  Conventionally, slot machines installed in game halls such as so-called pachinko shops can operate a lever-type start switch when a player inserts a desired number of medals (generally, a maximum of three). When the switch is tilted, the three reels rotate to start the game. On the peripheral surface of each reel, a plurality of types of symbols (generally 21) are drawn at equal intervals, and these symbols are in a certain direction (usually from top to bottom) as the reel rotates. Scroll display (variable display). When the player operates the stop switch provided for each reel after all the reels start rotating, the reel corresponding to the operated stop switch stops rotating and all the reels stop. When a symbol combination corresponding to some combination is displayed along a winning line (hereinafter referred to as an effective line) that is regarded as valid, the combination is established and a prize is awarded. In the case of winning, as a privilege to be given to the player, a medal payout device (hereinafter referred to as a hopper) provided in the slot machine is activated to pay out the number of medals according to the type of the winning combination. End a game. On the other hand, if the symbol combination stopped and displayed along the active line does not correspond to any combination, it is lost, and one game is finished as it is.

  Further, in the above-described slot machine, generally, when a start switch is operated, lottery of each combination determined in advance based on random numbers (hereinafter, this lottery is referred to as internal lottery) is performed. As a result of this internal lottery, if a winning combination is won, the slot machine will match the symbol combination corresponding to the winning combination in the internal lottery along the active line when the player operates the stop switch described above. The reel stop control is performed so that the stop display is displayed. On the other hand, if you do not win any of the roles in the internal lottery (if you lose), no matter what timing the player operates the stop switch, the symbol combination corresponding to any role will be on the active line. The stop control of the reels is performed so that the stop is not displayed along the line.

  In the slot machine described above, various countermeasures against fraudulent acts that cause losses to the game arcade have been proposed and implemented. For example, in the slot machine disclosed in Patent Document 1, two sensors for detecting the medal are provided in a passage path through which the inserted medal passes inside the slot machine, and the medal of the medal by the two sensors is provided. If the detection order and the time difference between detections are within a predetermined valid order and time, the medal inserted is counted as a normal medal inserted, otherwise error processing is performed. . By adopting such a configuration, in the slot machine disclosed in Patent Document 1, for example, a medal with a thread or the like is inserted and the thread is repeatedly pulled back to increase the number of inserted medals illegally. The act is prevented.

  Further, in the slot machine disclosed in Patent Document 2, the start switch is operated in order to counteract the illegal act of generating a strong electromagnetic wave externally and starting the rotation of the reel illegally without inserting a medal. The control signal to be detected is an active-low configuration in which the control signal is at a high level when not operated and is at a low level when operated. In addition, an electromagnetic wave detection circuit is provided, and the game process is stopped when the electromagnetic wave is detected.

  In addition, the slot machine disclosed in Patent Document 3 is provided with a sensor for detecting a medal paid out by the hopper so that the medal is not paid out illegally due to the above-described unauthorized operation on the hopper. When the above-mentioned sensor detects a medal despite no winning or no game being played, an abnormal payout signal is output to the management server to notify the attendant at the game hall and provided in the slot machine. The image display device notifies the occurrence of the illegal act and forcibly finishes the medal payout and the game.

  In addition, in the slot machine disclosed in Patent Document 4, a foreign object is inserted from a medal payout opening or the like, and the medal is not paid out due to an illegal operation of an internal device such as a hopper. A sensor for detecting foreign matter inserted from the medal payout opening is provided, and when the foreign matter is detected by the sensor, the medal payout exit or the like is closed by a closing plate.

  Furthermore, in the slot machine disclosed in Patent Document 5, the slot is prevented so that the player does not damage the slot machine by hitting or kicking the front portion of the slot machine and causing a loss in the game hall. A vibration detection sensor is provided inside the machine casing, and when abnormal vibration is detected by the vibration detection sensor, the game is controlled to be interrupted. Therefore, for example, when the player causes vibrations in the slot machine, the game is interrupted, so it can be expected that the player voluntarily refrains from such actions.

  By the way, in the conventional slot machine described above, an error process is performed when an illegal act is detected, and as this error process, for example, the number of input game media and the number of payout game media of each game machine installed in the game arcade, etc. It is disclosed that a management computer to be managed is notified that an abnormality has occurred. In addition, other error processing includes forcibly terminating the gaming control of the slot machine where the illegal act has been performed, and then controlling so that no gaming is possible, and outputting an alarm sound at the slot machine where the illegal act has been performed. It is also disclosed to perform control such as blinking a lamp and displaying a message indicating that an illegal act has been performed on an image display device.

  Among the error processing described above, in the slot machine in which fraud has been detected, the purpose of notifying that is to make it difficult for the fraud to occur by attracting the attention of those around (that is, prevention or suppression of fraud) There is. However, in recent gaming machines, in order to improve the fun of the game, the use of informing means such as lamps, speakers, image display devices, etc., the effects of light, sound, and images have become flashy, and fraudulent acts As a result, even if the notification using the notification means described above is performed only by the slot machine, it is becoming difficult to attract the interest of other players.

  Therefore, if a fraudulent act is performed, it is at least fraudulent if it is possible to report fraudulent activities not only in the slot machine in which the fraudulent act was performed but also in other slot machines installed around it. The effect of making it difficult to perform an action can be expected. In order to realize this, for example, it is conceivable to transmit a detection signal of fraudulent activity to another slot machine and perform notification in each slot machine that has received this detection signal. However, when the detection signal is transmitted to another slot machine by an electrical signal, it is necessary to connect each slot machine with a cable or the like, so a cable for connecting the slot machines to each other is separately required. The cost of equipment at the amusement hall will increase. In addition, when a new slot machine is installed or when a model of a slot machine already provided is replaced, the cable connection work becomes complicated.

  Accordingly, an object of the present invention is to notify each of a plurality of gaming machines installed in the vicinity that an illegal act has been carried out in a certain gaming machine without increasing the cost for the equipment of the game hall. It is to provide a gaming machine that can be used.

  In order to achieve the above object, the present invention variably displays a front door provided with an operation unit for performing an operation related to a game, and a plurality of symbols composed of a plurality of types of symbols based on operations on the operation unit. A gaming machine that includes a variable display means and provides a game that gives a player a privilege according to a stop display mode of the symbol displayed when the variable display is stopped, and an illegal act is performed. A fraud detection means for detecting this, a storage means for storing sound data corresponding to a plurality of types of sounds including a specific sound, and a speaker for outputting sound based on the sound data stored in the storage means to the outside When the cheating is detected by the cheating detection means, the sound data corresponding to the specific sound is read from the storage means, and the sound based on the read sound data is read from the speaker. A sound control means for outputting the sound, a microphone for converting an external sound into an electric signal, and a specific sound for determining whether or not the specific sound is generated externally based on the electric signal output from the microphone The information processing apparatus includes: a determination unit; and a notification unit that notifies that the illegal act has been performed based on the determination that the specific sound is generated outside by the specific sound determination unit.

  Here, the variable display means is composed of, for example, a plurality of reels having a plurality of symbols drawn on the outer peripheral surface, and performs variable display of the symbols by rotating the reels, or a plurality of symbol rows, respectively. An image display device that performs scroll display is applicable. The symbol stop display mode refers to, for example, a combination of symbols displayed when the rotation of the plurality of reels described above is stopped or when scroll display is stopped in the image display device. Further, to give a privilege to the player according to the stop display mode of symbols, for example, when a predetermined symbol combination is displayed when variable display of the variable display means is stopped, a well-known slot machine As in the case of paying out a predetermined number of medals to the player, or a so-called “big hit” in a known pachinko machine, a win (that is, paying out a game ball) is much higher than usual. It means that it becomes easy to do. Furthermore, examples of the notification means include sound source data and a speaker for generating sound, a light emitter that generates light, an image display device that displays an image, and a vibration generator that generates vibration.

  According to the present invention, when an illegal act is detected in a certain gaming machine, audio data corresponding to the specific sound is read from the storage means, and the specific sound is output from the speaker. Further, when the specific sound is converted into an electric signal by the microphone and is determined to be the specific sound, it is notified that an illegal act has been performed by, for example, sound, light, image, vibration, or the like. That is, for example, in a state where a plurality of gaming machines of the present invention are installed, when a specific sound is generated from a speaker of a certain gaming machine, the specific sound is captured by a microphone provided in another gaming machine, and the other gaming machine It is informed that fraudulent acts have been carried out in each machine. This informs the players around the gaming machine that other illegal gaming machines are being used directly, so that other players should be more careful than conventional gaming machines. It can be attracted and can be expected to increase the deterrence effect of fraud. In addition, it is not necessary to connect the gaming machines with a cable or the like in order to transmit the fact that the illegal act has been performed to other gaming machines. The work at the time of new establishment or replacement can be facilitated.

  Further, the present invention is the gaming machine described above, wherein the cheating is performed when the cheating detection means performs an act of acquiring a privilege given to the player by an cheating method. It is characterized by detecting.

  Here, “an act of acquiring a privilege granted to a player by an unauthorized method” means, for example, an act of starting a game without inserting a game medium such as a medal or a game ball into the game machine, The act of taking out stored game media without depending on the result of the game, the action of changing the winning probability of the combination in the internal lottery described above without depending on the result of the game, and the like.

  According to the present invention, when it is detected that an act of acquiring a privilege given to the player by an unauthorized method is performed, a specific sound is output from the speaker, and the specific sound is transmitted to the electric signal by the microphone. If it is determined that the sound is a specific sound, for example, it is notified that an illegal act has been performed by sound, light, image, vibration, or the like. Thereby, the effect which suppresses the fraud which reduces the sales of a game hall can be expected.

  Further, according to the present invention, in any one of the above-described games, the cheating detection means detects vibration caused by an impact applied to the front door, and the cheating is performed when the vibration is detected. It is characterized by detecting this.

  According to the present invention, when vibration caused by an impact applied to the front door is detected, a specific sound is output from the speaker, and the specific sound is converted into an electric signal by the microphone. If it is determined that there is, for example, it is notified that an illegal act has been performed by sound, light, image, vibration, or the like. As a result, for example, it can be expected that the player can damage the gaming machine by hitting or kicking the gaming machine and, as a result, suppress an act that may increase the maintenance cost of the gaming machine.

  According to the gaming machine of the present invention, each of a plurality of gaming machines installed around the gaming machine is informed that an illegal act has been performed in a certain gaming machine without increasing the cost for the equipment of the game hall. be able to.

  Next, with reference to FIG. 5, the structure of the main control part which controls the game in the slot machine 1 is demonstrated. In this figure, the same parts as those shown in FIGS. 1 and 3 are denoted by the same reference numerals, and detailed description thereof is omitted. The main control unit 30 includes a microcomputer (hereinafter referred to as a microcomputer) 31 disposed on a circuit board as a main component, and is added to a circuit for random number sampling. The microcomputer 31 includes a main CPU 32, a program ROM 33, a control RAM 34, and an I / O port 35. The program ROM 32 stores a game control program executed by the main CPU 32 and various tables referred to in the process of executing the game control program.

  Here, the contents of the main table stored in the program ROM 33 will be described with reference to FIGS. FIG. 6 is a symbol arrangement table showing information related to each symbol row shown in FIG. 2, and FIG. 7 is role data representing a predetermined combination and a combination won in the internal lottery in the game provided by the slot machine 1. FIG. 8 is an internal lottery table that defines the winning probability of each combination in the internal lottery. FIG. 8 is a symbol combination table that defines the correspondence between the contents of 9 is an internal winning combination determination table to be referred to when converting the result of the internal lottery into data corresponding to a specific type of combination (hereinafter referred to as internal winning combination data), and FIG. 10 is an RB game (described later). The contents of the bonus operation time table including data relating to the end condition of (Yes) are shown.

  As shown in FIG. 6, the symbol arrangement table corresponds to the symbol numbers assigned to the 21 symbols drawn on the surfaces of the reels 4L, 4C, and 4R shown in FIG. 2, and the symbol numbers. A numerical value (symbol code) indicating the type of symbol to be associated is associated. The symbol code is 1-byte data, “Red 7” symbol RS is “1” in decimal, “Blue 7” symbol BS is “2” in decimal, and “Watermelon” symbol WM is “3” in decimal. ”,“ Bell ”symbol BE is decimal number“ 4 ”,“ Red Cherry ”symbol RC is decimal number“ 5 ”,“ Peach Cherry ”symbol PC is decimal number“ 6 ”, and“ Plum ”symbol PL is 10. The decimal number is “7”, and the blank symbol BL is “8” in decimal. In FIG. 6, the value of the symbol code described above is represented by a binary number.

  As shown in FIG. 7, the symbol combination table includes a symbol combination displayed along the active line when the reels 4L, 4C, and 4R are stopped, data indicating a predetermined role type, The number of medals paid out when each combination is established is associated with each other. That is, when the symbol combination shown in FIG. 7 is stopped and displayed along one of the effective lines, a combination corresponding to the symbol combination is established, and neither symbol combination is stopped and displayed. Becomes “losing”. There are eight types of roles: “small role 1”, “small role 2”, “small role 3”, “small role 4”, “replay”, “RB1”, and “RB2”. Here, in the symbol combinations corresponding to “small role 1” and “small role 2”, “ANY” is illustrated as the symbol of the middle reel 4C and the right reel 4R. Even if is stopped, it indicates that the winning combination is established. That is, in the left reel 4L, when the “red cherry” symbol is stopped along any active line, “small role 1” is established, and when the “peach cherry” symbol is stopped, “small role 2” is It is established.

  Among the above-mentioned combinations, when “small combination 1”, “small combination 2”, “small combination 3”, and “small combination 4” are established, the number of medals corresponding to the combination (see FIG. 7) is the player. Will be paid out. In addition, when “Replay” is established, in the next game, the same number of medals as the number of medals inserted in the game in which the “Replay” is established are automatically inserted into the slot machine 1, and the game The player can play the game without consuming the medals he owns. Furthermore, when “RB1” or “RB2” is established, an RB game is started from the next game, and a game in which “small role 3” is established with high probability until a predetermined end condition (described later) is satisfied. It can be carried out. Hereinafter, “RB1” and “RB2” are collectively referred to as a bonus combination.

  Further, in the slot machine 1, when the RB game is finished, a transition is made to a replay time (hereinafter referred to as RT) in which “replay” is established with a high probability. This RT is continued until a predetermined number of games are performed or one of the “small role 1”, “RB1”, and “RB2” roles is established, during which the probability that “replay” is established increases. Therefore, the player can play a game while suppressing consumption of medals. Therefore, if it can be avoided that the symbol combination corresponding to “small role 1” is stopped and displayed along the active line during RT, the predetermined number of games is consumed until the RB game is started. Until then, RT can be continued. That is, RT (a state in which a game can be performed while suppressing consumption of medals) can be prolonged as much as possible. Hereinafter, the state during the RB game is referred to as the RB gaming state, the state during the RT is referred to as the RT gaming state, and the states other than the RB gaming state and the RT gaming state are referred to as the general gaming state.

  As shown in FIGS. 8A to 8C, the internal lottery table is generated from each winning number and a random number generator 38, which will be described later, and is sampled by the sampling circuit 39 (the generation range of random values is “0” to “65535”) are associated with a lower limit value and an upper limit value for determining which winning number corresponds to the winning number. That is, for example, in a game played with three medals inserted, when an internal lottery is performed using the internal lottery table shown in FIG. 8A, a random number value “2564” is sampled by the sampling circuit 39. If it is, the result of the internal lottery is that the winning number is “7”. On the other hand, if the sampled random number value does not belong to any numerical range defined by the internal lottery table, the winning number is determined to be “0”. 8 (a) to 8 (c), the column shown as “width” shows a value obtained by subtracting the lower limit value from the upper limit value corresponding to each winning number and adding 1. . Therefore, a value obtained by dividing the value shown in the “width” column by the number of random values that can be generated (65536) is the winning probability of each winning number.

  Here, FIG. 8A shows an internal lottery table used when the slot machine 1 is in the general gaming state, and the winning numbers “1” to “1” A lower limit value and an upper limit value corresponding to “7” are defined, and the winning probability of each winning number increases as the number of inserted sheets increases. FIG. 8B shows an internal lottery table used in the RT gaming state, and the winning probability of the winning number “5” is higher than that in the general gaming state. The winning numbers other than the winning number “5” have the same winning probability as in the general gaming state. FIG. 8C shows an internal lottery table used in the RB gaming state, and a lower limit value and an upper limit value corresponding to the winning numbers “1” to “4” are defined. As a result, in the RB gaming state, the winning numbers “5” to “7” that are the targets of the internal lottery in the general gaming state and the RT gaming state are not subject to the internal lottery. Further, the winning probability of the winning number “3” is higher than the internal lottery table used in the general gaming state and the RT gaming state.

  Next, as shown in FIG. 9, in the internal winning combination determination table, flag data actually stored in the control RAM 34 as a result of the internal lottery is determined for each of the winning numbers “0” to “7”. ing. This flag data is represented in binary in the “data” column of the table shown in FIG. 9, and is composed of 1-byte data as shown in this figure. Also, the winning number “0” is “losing”, the winning number “1” is “small role 1”, the winning number “2” is “small role 2”, the winning number “3” is “small role 3”, and the winning number “4” corresponds to “small role 4”, the winning number “5” corresponds to “replay”, the winning number “6” corresponds to “RB1”, and the winning number “7” corresponds to “RB2”. Also, the winning numbers “1” to “7” shown in FIG. 9 correspond to the winning numbers shown in FIG. Therefore, it can be seen that the winning probability of “replay” is high in the RT gaming state (see FIG. 8B). Also, in the RB gaming state, the winning probability of “small role 3” is high, and it can be seen that “replay”, “RB1”, and “RB2” are not subject to lottery (see FIG. 8C). ).

  Next, the bonus operation time table defines data to be stored in each storage area previously defined in the control RAM 34 when the RB game is started. In other words, in the control RAM 34, an operating flag possible area in which data indicating that the RB gaming state is stored, and the number of possible games in which data for counting the number of games played during the RB game are stored are stored. A count area and a winning possible count area where data for counting the number of times a winning combination is established during the RB game are stored are defined. Then, when the start of the RB game is determined, a value “00000001” in the binary number shown in FIG. 10 is stored in the operating flag storage area of the control RAM 34, and “12” is stored in the possible game count area. Then, “8” is stored in the countable area for the number of winnings possible. As a result, after the transition to the RB game, every time a game is played, the value stored in the possible game count area is decremented by 1, and every time a winning combination is established, it is stored in the possible win count count area. One value is subtracted by one. When the value stored in any one of these count areas becomes “0”, the RB game ends and the process proceeds to RT. Accordingly, it can be said that the RB game end condition is stored in the bonus operation time table.

  Next, with reference to FIG. 11, main storage areas for data relating to games provided in the control RAM 34 will be described. Here, FIG. 11A shows the contents of the internal winning combination storing area in which the flag data obtained by the internal winning combination determination table shown in FIG. Yes. FIG. 11B shows the contents of the carryover combination storage area in which the flag data is stored only when “RB1” or “RB2” is determined in the internal lottery. Further, FIG. 11C shows the contents of the operating flag storage area described above.

  The internal winning combination storage area shown in FIG. 11A has an 8-bit storage area from bit 0 to bit 7, and in the figure, bit 0 is the least significant bit (hereinafter the same applies to other storage areas). It has become. Therefore, as is clear from the internal winning combination determination table shown in FIG. 9, when the internal lottery results in “losing”, bits 0 to 7 are all “0”. In addition, when winning “small role 1” in the internal lottery, only bit 0 wins “1”. When winning “small role 2”, only bit 1 wins “1” and “small role 3”. When only bit 2 wins “1” and “small role 4”, only bit 3 wins “1”, and when “replay” wins, only bit 4 wins “1” and “RB1” When only bit 5 wins “1” and “RB2” is won, only bit 6 becomes “1”. Bit 7 is always “0”. Therefore, from a different perspective, each of the bits 0 to 6 can be said to be a winning combination flag storage area indicating whether or not the corresponding combination is won by internal lottery. The data in the internal winning combination storing area is cleared every time one game is completed.

  In addition, the carryover combination storage area shown in FIG. 11B also has an 8-bit storage area from bit 0 to bit 7, and when “RB1” is won by internal lottery, only bit 6 is “1”, “ When “RB2” is won, only bit 5 is “1”, and other bits are always “0”. When “1” is stored in bit 5 or bit 6, the state is maintained until the RB game is started, and is cleared when the RB game is started. Therefore, when the internal winning combination (“RB1” or “RB2”) that will start the RB game is determined, the state of the winning combination flag is carried over until the RB game is started. it can. Therefore, “RB1” and “RB2” are also referred to as “carryover”. In addition, while “1” is stored in bit 5 or bit 6 of the carryover combination storage area, the combination corresponding to the bit storing “1” is also an internal symbol regardless of the random number value to be sampled. It is considered as a role. That is, for example, when “1” is stored in bit 6 of the carryover combination storage area and “1” is stored in any bit of the internal winning combination storage area shown in FIG. Both the combination corresponding to the bit and “RB1” are regarded as internal winning combinations. Furthermore, since the carryover combination is determined based on the internal winning combination, it can be said to be a subordinate concept of the internal winning combination.

  In the operating flag storage area shown in FIG. 11C, “1” is stored in bit 0 when the RB game is being played, and bit “0” is set when the RB game is not being played. Stored. Bits 1 to 7 always store “0”.

  Returning to FIG. 5, a clock pulse generation circuit 36, a frequency divider 37, a random number generator 38, a sampling circuit 39, and a timer 40 are connected to the main CPU 32. The clock pulse generation circuit 36 and the frequency divider 37 generate a reference clock signal and an interrupt signal. Based on these signals, the main CPU 32 performs game control processing, interrupt processing, and the like, which will be described later. The random number generator 38 generates a random number within a certain range (for example, 0 to 65535). The sampling circuit 39 samples one random number value from the random number generated by the random number generator 38 when the start switch 13 shown in FIG. 1 is tilted by the player. The timer 40 starts or ends time measurement according to an instruction from the main CPU 32, and outputs the measured time to the main CPU 32.

  In FIG. 5, the main output devices whose operation is controlled by a control signal from the microcomputer 31 include various displays of the game information display unit 7, a hopper 51 for storing medals (a drive unit for payout). And stepping motors 22L, 22C, and 22R for rotationally driving the reels 4L, 4C, and 4R. The microcomputer 31 drives and controls the 1-BET lamp 9a, the 2-BET lamp 9b, the maximum BET lamp 9c, the insert lamp 9d, the replay display lamp 9e, and the start lamp 9f via the LED drive circuit 41. Further, the microcomputer 31 performs drive control of the 7-segment display 8 via the display unit drive circuit 42.

  Further, the microcomputer 31 drives and controls the hopper 51 by outputting a drive command to the hopper drive circuit 43, and drives the stepping motors 22L, 22C and 22R by outputting a drive pulse signal to the motor drive circuit 44. Control. These various drive circuits are connected to the main CPU 32 via the I / O port 35 described above, and control the operation of the corresponding output device by receiving control signals such as drive commands output from the main CPU 32, respectively. To do. That is, when a driving command is output from the microcomputer 31, the hopper driving circuit 43 supplies a driving current to the driving unit of the hopper 51 to pay out medals stored in the hopper 51, and the output of the driving command is When stopped, the supply of the drive current is stopped, and the payout of medals from the hopper 51 is stopped. And the medal paid out from the hopper 51 is discharged | emitted from the medal discharge port 16 shown in FIG.

  Further, each time the driving pulse signal corresponding to each stepping motor is output from the microcomputer 31, the motor driving circuit 44 rotates the corresponding stepping motor one step at a time. The main CPU 32 counts the number of drive pulses output to each stepping motor, and a reel index provided only at a predetermined location on each reel 4L, 4C, 4R detects the reel position. When the index detection signal detected by the circuit 45 and corresponding to the index detection signal is output from the reel position detection circuit 45 to the main CPU 32 via the I / O port 35, the main CPU 32 calculates the number of drive pulses counted. clear. As a result, the main CPU 32 counts the number of drive pulses output to the stepping motors 22L, 22C, and 22R to thereby determine the position of each reel in the rotation direction (reel position based on the position where the reel index is detected). It can also be said to be a rotation angle.

  Specifically, gears (not shown) that transmit the rotations of the stepping motors 22L, 22C, and 22R to the reels 4L, 4C, and 4R at a predetermined reduction ratio are provided, and the stepping motors 22L, 22C, and 22R are provided. On the other hand, when 16 drive pulse signals are output, one symbol drawn on the outer peripheral surface of each reel is rotated. That is, since 21 symbols are drawn on the outer peripheral surface of each reel, the main CPU 32 has 21 (number of symbols) × 16 (number of drive pulses required to rotate by one symbol) = 336 drives. When a pulse is output, the reel rotates once.

  The number of drive pulses output to the stepping motors 22L, 22C, and 22R described above is stored in a pulse count area provided in the control RAM 34, and the main CPU 32 stores numerical values stored in the pulse count area. Each time becomes a multiple of 16, the numerical value stored in the symbol count area provided in the control RAM 34 is incremented by one. This symbol count area is provided corresponding to each of the reels 4L, 4C, 4R, and the stored value is cleared each time an index detection signal is output from the reel position detection circuit 45. Here, in the above-described reel index, the center of the symbol area of the symbol corresponding to the position where the reel index is provided (the area divided by the broken line in FIG. 2) coincides with the middle line L3 shown in FIG. Sometimes, it is provided at a position detected by the reel position detection circuit 45. Therefore, if the symbol corresponding to the position where the reel index is provided is the symbol of symbol number “0” in each symbol row shown in FIG. 2, the value stored in the count area from the above-described diagram, that is, The main CPU 32 can recognize the type of symbol displayed on each of the reel display windows 4L, 4C, 4R based on the symbol number located on the middle line L3.

  Next, as main input devices for generating an input signal necessary for the microcomputer 31 to generate a control command, stop switches 5L, 5C, 5R, medal sensors 124, 125 (to be described later), BET switches 11, 12, a start There are switches such as a switch 13, a medal discharge switch 14, vibration detectors 20A and 20B (see FIG. 4), and a door opening / closing switch 21 (see FIG. 1). Signals output from these switches are output to the main CPU 32 via the I / O port 35. For the stop switches 5L, 5C, 5R, a stop instruction signal corresponding to the stop switch pressed by the player is output from the reel stop signal circuit 52, and is output to the main CPU 32 via the I / O port 35. The

  The above-mentioned medal sensors 124 and 125 are incorporated in a selector attached to the back surface of the front door 2a. This selector sorts medals inserted into the medal slot 10 shown in FIG. 1 into appropriate ones and improper ones. The medals selected as appropriate medals by the selector are medal sensors. After being detected by 124 and 125, it is sent to the hopper 51. Here, the structure of the selector described above will be described with reference to FIG. 12A shows a front view of the selector, and FIG. 12B shows a rear view of the selector. As shown in FIG. 12A, the selector has a guide member 101 attached to the front side of the rectangular substrate 100, thereby forming a medal path 102 indicated by a broken line in FIG. . The medal passage 102 is formed vertically from an entrance 103 through which a medal inserted from the medal insertion slot 10 enters, and is formed so as to draw a curve in the middle to change to an inclined road and reach the selector exit 104. Yes. A magnet 105 is provided on the upstream side of the slope portion of the medal passage 102, and perforations 106 and 107 are provided on the lower side of the magnet 105.

  From the above-described perforations 106 and 107, protrusions 110a and 110b of the protrusion member 110 (see FIG. 12B) are provided so as to be able to appear and retract. As shown in FIG. 12B, the first projecting member 110 is pivotally supported by a shaft 113, and is urged by a spring 114 in a direction in which the projecting portions 110 a and 110 b project from the wall surface of the medal passage 102. . Further, on the downstream side of the slope of the medal passage 102, a perforation 108 is provided substantially in the center in the height direction of the medal passage 102, and a perforation 109 is provided below the perforation 108. From the perforation 108, the projection 111a of the second projecting member 111 (see FIG. 12B), and from the perforation 109, the projection of the movable guide plate 112 (the portion indicated by hatching in FIG. 12B). 112a is provided so that it can freely appear and disappear.

  Further, on the substrate 100, a push plate 115 (a portion indicated by hatching in FIG. 12A) and a movable guide are provided so that the medal M passing through the medal passage 102 does not drop out toward the front side of the sheet of FIG. A plate 112 is attached. The push plate 115 has an opening 115a at a position corresponding to the slope portion of the medal passage 102, and rotates around a shaft 118 that can be attached to and detached from bearings 116 and 117 formed to protrude from the surface of the substrate 100. It is attached freely. Further, the lower portion of the push plate 115 is biased by the spring 119 wound around the shaft 118 so as to contact the guide member 101.

  When the medal return lever 10R shown in FIG. 1 is pressed by the player, a link member (not shown) linked to this movement is an opening member 120 (FIG. 12B) provided on the back surface of the substrate 100. Press down on the top edge of As a result, the upper end portion of the opening member 120 rotates from the back side to the near side in FIG. 12B around the rotation shaft 121, and the lower portion 120 a of the opening member 120 protrudes from the surface of the substrate 100. The push plate 115 is pushed out from the back surface. As a result, the push plate 115 rotates about the shaft 118, and the lower portion of the push plate 115 is separated from the guide member 101. For example, when the medal M is clogged in the medal passage 102, the push plate 115 is removed from the medal passage 102. It drops off and is discharged from the medal discharge port 16 shown in FIG.

  On the other hand, the movable guide plate 112 is in the position shown in FIG. 12A when the selector solenoid 122 shown in FIG. 12B is excited to attract the movable iron piece 123, and the movable guide plate 112 protrudes. The portion 112 a is retracted from the vertical wall surface of the medal passage 102. At this time, when the medal M enters the inlet 103 of the selector, the flowing medal M is guided by the movable guide plate 112 and passes through the inclined path of the medal passage 102 without dropping from the opening 115 a of the push plate 115. The medal M passing through the ramp is detected by medal sensors 124 and 125 provided near the outlet 104 of the selector, and then sent out from the outlet 104 to the hopper 51 described above. The medal detection signals output from the medal sensors 124 and 125 are output to the main CPU 32 via the I / O port 35 shown in FIG. Here, when the medal sensors 124 and 125 detect medals, the medal detection signal is ON, and when no medals are detected, it is OFF. In the following, when referring specifically to the medal sensors 124 and 125, the medal sensor 124 provided on the upstream side of the medal passage 102 is referred to as a first medal sensor, and the medal sensor 125 provided on the downstream side thereof is referred to as the first medal sensor 125. It is called 2 medal sensor.

  On the other hand, when the selector solenoid 122 is not excited, the spring 126 shown in FIG. 12 (b) contracts in the depth direction of the paper surface, so that the movable iron piece 123 rotates around the support member 127 as a fulcrum. The solenoid 122 and the movable iron piece 123 are separated from each other. As a result, the movable guide plate 112 rotates from the back direction to the near side about the rotation shaft 128 shown in FIG. Further, along with this movement, the protrusion 112 a protrudes from the vertical wall surface of the medal passage 102. As a result, the movable guide plate 112 moves upward from the position shown in FIG. 12A. At this time, when the medal M passes through the medal passage 102, the projecting portions 110a and 110b of the first projecting member 110 described above are used. The medal M is pushed out toward the front side of the paper, dropped from the opening 115a of the push plate 115, and discharged from the medal outlet 16 shown in FIG.

  As described above, when the selector solenoid 122 is not energized, the spring 126 shown in FIG. As a result, the protrusion 111 a of the second protrusion member 111 protrudes from the vertical wall surface of the medal passage 102. In addition, when the selector solenoid 122 is excited, the lower end 123 a of the movable iron piece 123 is separated from the second projecting member 111, so that the second projecting member 111 is rotatable about the rotating shaft 129. However, the weight of the weight 111b formed at the lower end of the second projecting member 111 causes the second projecting member 111 to rotate in the direction in which the projecting portion 111a sinks from the vertical wall surface of the medal passage 102.

  In the selector having the above-described structure, when the diameter of the medal inserted from the medal insertion slot 10 is larger than the standard, the medal passage 102 cannot be entered from the entrance 103, and when the medal is smaller than the standard, the medal On the inclined path of the passage 102, it drops out of the opening 115a of the push plate 115 and is discharged from the medal discharge port 16 shown in FIG. Further, even if the diameter of the medal conforms to the standard, when the selector solenoid 122 is not excited, the medal shown in FIG. 1 falls off the opening 115a of the push plate 115 on the slope of the medal path 102. It is discharged from the discharge port 16 to the medal tray 17.

  Returning to FIG. 5, the main CPU 32 also receives a signal output from a medal detection unit 53 that detects medals paid out by the hopper 51. The medal detection unit 53 outputs a detection signal to the payout signal generation circuit 46 in the main control unit 30 every time the hopper 51 ejects one medal. Accordingly, the payout signal generation circuit 46 outputs the detection signal output from the medal detection unit 53 to the main CPU 32 via the I / O port 35, and the main CPU 32 outputs the detection signal input count (the hopper 51 has paid out). When the number of medals reaches the target number of times (for example, the number of payouts corresponding to the established combination or the number of medals stored in the slot machine 1), the drive command to the hopper drive circuit 43 Stops output. Further, the main CPU 32 transmits various information (commands) related to the game being executed in the slot machine 1 to the sub control unit 60 via the sub control unit communication port 47 connected to the I / O port 35. . Based on these commands, the sub-control unit 60 executes effects and various notifications by images and sounds as will be described later.

  Next, the configuration of the sub-control unit 60 will be described with reference to FIG. The main control unit 30 controls the progress of a series of games, such as determination of internal winning combination and reel control, while the sub control unit 60 is a combination of images, sounds, lights, or combinations thereof. The production is performed by controlling the output. The main control unit 30 and the sub control unit 60 are electrically connected by a harness or the like, and the sub control unit 60 performs various operations such as determination and execution of effect contents based on various commands transmitted from the main control unit 30. Process. The sub control unit 60 includes a sub CPU 61, a control ROM 62, a work RAM 63, an I / F circuit 64, an image control unit 65, a musical sound control unit 66, a lamp driver 67, a band pass filter 68, and a comparator 69. .

  The control ROM 62 includes a program storage area and a data storage area. The program storage area stores an effect control program. Specifically, an operating system, a device driver, an inter-board communication task for performing reception control of various commands transmitted from the main control unit 30, and voice control for controlling sound output from the speakers 18L, 18R, and 18B. Task, LED control task for controlling the light output from the upper lamp 19 (see FIG. 1), effect registration task for determining the contents of the effect (such as effect data described later), and the content of the determined effect A drawing control task for controlling an image to be displayed on the liquid crystal display device 3 is included. The data storage area of the control ROM 62 includes a table storage area for storing various tables related to the determination of the contents of the effect, a drawing control data storage area for storing animation data such as character object data, BGM, sound effects, and a specific A voice control data storage area for storing sound data (digital data) such as sound (to be described later), an LED control data storage area for storing light lighting patterns, and the like. Therefore, the control ROM 62 corresponds to a storage unit that stores audio data corresponding to a plurality of types of sounds including a specific sound.

  The work RAM 63 is used by the sub CPU 61 as a temporary storage means for work in the process of executing the aforementioned effect control program. The I / F circuit 64 receives various commands transmitted from the main control unit 30 and outputs the received commands to the sub CPU 61. The image controller 65 includes a rendering processor 651, an SDRAM 652 having a frame buffer, and a liquid crystal driver 653. The rendering processor 651 is connected to the sub CPU 61 and performs rendering in accordance with a command output from the sub CPU 61. Data necessary for a task performed by the rendering processor 651 is expanded in the SDRAM 652 at the time of activation. Then, pixel array data corresponding to the image created by rendering is transferred to the frame buffer and output to the liquid crystal display device 3 via the liquid crystal driver 653.

  The tone control unit 66 includes a D / A converter 661 and a power amplifier 662. The D / A converter 661 converts sound data read from the sound control data storage area of the control ROM 62 by the sub CPU 61 into an analog sound signal and outputs the analog sound signal to the power amplifier 662. The power amplifier 662 amplifies the analog audio signal output from the D / A converter 661 and outputs it to the speakers 18L, 18R, 18B. As a result, the analog audio signal amplified by the power amplifier 662 is output as sound from the speakers 18L, 18R, 18B to the outside. The lamp driver 67 drives the upper lamp 19 to emit light with a light emission pattern corresponding to the command output from the sub CPU 61.

The band pass filter 68 passes only a signal in a specific frequency band among the electric signals output from the microphones 6L and 6R. In other words, an electrical signal outside a specific frequency band is greatly attenuated and output. Here, the specific frequency band which the band pass filter 68 passes is demonstrated with reference to FIG. The diagram shown in FIG. 14 is a graph showing the frequency characteristics of electrical signals output from the microphones 6L and 6R, with the horizontal axis representing frequency and the vertical axis representing sound pressure level. Electrical signal output from the microphone 6L, 6R is obtained by converting a sound into an electric signal, in this figure, the frequency f ₀ indicates the human audible frequency range between the upper limit (generally 20 kHz). Further, BW indicated by a broken line in FIG. 14B indicates the passband width of the bandpass filter 68. As shown in FIG. 14 (b), the center frequency of the pass band width BW is set to a higher frequency (i.e. audible frequency range) f ₁ than the frequency f _0, the frequency f _1, the center of the specific sound It matches the frequency.

When specific sounds are generated around the slot machine 1, these sounds together with the audible sounds are converted into electric signals by the microphones 6 </ b> L and 6 </ b> R and output to the bandpass filter 68. Thereby, only the electric signal corresponding to the specific sound whose center frequency is f ₁ is output from the band pass filter 68. Here, as long as each bandpass filter 68 has a pass bandwidth that allows only an electrical signal of a specific sound to pass, even if it is an analog filter composed of a resistor, a capacitor, a coil, etc., the digital signal once It is also possible to use a digital filter that converts the signal into an analog signal and performs an appropriate signal processing, and then converts the signal again into an analog signal.

  The comparator 69 compares the level of the electrical signal output from the band pass filter 68 with a predetermined reference level. When an electrical signal exceeding the reference level is output from the corresponding band pass filter, the comparator 69 outputs a high level ( Hereinafter, a digital signal at the H level is output. Otherwise, a digital signal at the low level (hereinafter referred to as the L level) is output.

  Next, the operation of the slot machine 1 having the above-described configuration will be described with reference to the drawings shown in FIGS. Here, FIG. 15 is a flowchart showing a flow of game control processing executed by the main CPU 32 of the main control unit 30. FIGS. 16 to 21 are flowcharts showing the detailed flow of each process performed in the above-described game control process.

  24 to 27 are flowcharts showing the flow of each process executed by the sub CPU 61 of the sub control unit 60. FIG. 24 shows various signals output from the main control unit 30 or the microphones 6L and 6R. FIG. 25 is an effect registration process for executing an effect based on the command output from the main control 30. 26 is a flowchart showing a detailed flow of the effect content determination process executed in the process of the effect registration process shown in FIG. 25, and FIG. 27 is executed in the process of the effect content determination process shown in FIG. It is a flowchart which shows the detailed flow of an effect lottery process.

  When the slot machine 1 is powered on, the main CPU 32 starts the game control process shown in FIG. First, the main CPU 32 performs an initialization process (step S1). In this process, a process of restoring the register data and execution address stored in the control RAM 34 when the power supplied to the slot machine 1 is cut off is performed. Next, the main CPU 32 clears the designated storage area in the control RAM 34 (step S2). In this process, for example, data stored in the internal winning combination storing area shown in FIG. Next, the main CPU 32 automatically inserts the number of medals inserted at the time when “replay” is established in the previous game by performing medal acceptance / start check processing described later. For example, the inputs of the medal sensors 124 and 125 or the BET switches 11 and 12 shown in FIG. 5 are checked, the inserted number stored in the control RAM 34 is updated, and whether or not the start switch 13 is operated is checked. (Step S3). In step S3, when it is determined that a predetermined number of medals have been inserted and the start switch 13 has been tilted, the main CPU 32 extracts random values and stores them in a random value storage area provided in the control RAM 34. (Step S4).

  Next, the main CPU 32 performs an internal lottery process to be described later (step S5). In this process, it is determined whether the random number value stored in the random number value storage area belongs to a plurality of numerical value ranges defined in the internal lottery table (see FIG. 7) stored in the program ROM 33. The internal winning combination is determined. This internal lottery process corresponds to stop display mode determination means. Next, the main CPU 32 transmits a start command including various data relating to the game such as an internal winning combination to the sub-control unit 60 (step S6). Next, the main CPU 32 requests the start of rotation of all reels (step S7). When the start of rotation of all the reels is requested, processing for starting the rotation of the reels is performed in an interrupt process described later. Then, the main CPU 32 stands by until the reel rotation speed reaches a predetermined constant speed (for example, 80 rotations / minute) (step S8).

  Next, the main CPU 32 performs a reel stop control process (step S9). In this process, a process of stopping the rotation of all the reels 4L, 4C, 4R based on the detection of the stop operation is performed. This reel stop control process corresponds to variable display stop means. Next, the main CPU 32 refers to the symbol combination table (see FIG. 7), and performs a winning determination that determines whether or not any combination has been established based on the symbol combination that is stopped and displayed along the active line (step). S10). More specifically, the symbol combination set in the symbol combination table shown in FIG. 7 is compared with the symbol combination displayed along the active line. And the values of the winning combination storage area and the payout number count area in the control RAM 34 are updated. Here, the winning combination storage area has the same contents as the internal winning combination storage area shown in FIG. 11A (that is, the correspondence between bit 0 to bit 6 and each combination is the same, and bit 7 is always “0”. The data stored in the storage area is the same as the internal winning storage area. The winning combination storage area is different in meaning from the data stored in the internal winning combination storage area in that all reels stop and data corresponding to the actual winning combination is stored. If the symbol combination set in the symbol combination table shown in FIG. 7 does not match, the data corresponding to “lost” (that is, “00000000” in binary) is stored in the winning combination storage area. . Next, the main CPU 32 transmits a winning combination command to the sub-control unit 60 (step S11). The winning combination command includes data indicating a winning combination including “losing”. Next, the main CPU 32 performs medal payout processing (step S12). In this process, the control of the hopper 51 shown in FIG. 5 and the display of the 7-segment display 8 shown in FIG. 3 are updated based on the determined payout number.

  Next, the main CPU 32 refers to the operating flag storage area shown in FIG. 11C and determines whether or not the RB operating flag is on (step S13). When the main CPU 32 determines that the RB operating flag is on, the main CPU 32 performs a bonus end check process (step S14). In this process, a process for ending the RB game is performed based on various count areas updated during the operation of the RB game. When the main CPU 32 finishes the process of step S14 or determines that the RB operating flag is not on in step S13, the main CPU 32 updates the value stored in the RT game number count area (step S15). ). Specifically, it is determined whether or not the value of the RT game count area provided in the control RAM 34 is “0”, and when it is determined that the value of the count area is not “0”, the RT game count is counted. The value of the area is subtracted by “1”. In the RT game number counting area, data for counting the number of games played during RT operation is stored, but the value of this data does not fall below “0”, and this value is “0”. Sometimes, even if “1” is subtracted, it remains in the “0” state. Next, the main CPU 32 performs a bonus operation check process (step S16). In this process, a process for starting the RB game is performed based on the established combination. When this process ends, the process proceeds to step S2, and thereafter, the processes of steps S2 to S16 are repeatedly performed.

  Next, with reference to FIG. 16, the medal acceptance / start check process in step S3 of the game control process shown in FIG. 15 will be described. First, the main CPU 32 determines whether or not the value of the automatic insertion count area is “0” (step S20). This automatic insertion count area is a storage area preset in the control RAM 34. As will be described in detail later, when “replay” is established in the previous game, the number of medals inserted into the game is stored. ing. When determining that the value of the automatic insertion count area is “0”, the main CPU 32 permits medal passage (step S21). Specifically, the selector solenoid 122 shown in FIG. 12 is driven to allow medals in the selector to pass. On the other hand, when the main CPU 32 determines that the value of the automatic insertion count area is not “0”, the main CPU 32 copies the value of the automatic insertion count area to the insertion number count area (step S22). Here, the inserted number count area is a storage area preset in the control RAM 34, and stores data indicating the number of medals inserted in one game. Thereafter, the main CPU 32 clears the value of the automatic insertion count area (step S23).

  When the processing of step S21 or step S23 is completed, the main CPU 32 performs an illegal act on the insertion of medals into the medal slot 10 based on the output signals from the medal sensors 124 and 125 shown in FIG. A medal detection process for determining whether or not it has been received is performed (step S24). This medal detection process will be described in detail later. Next, the main CPU 32 determines whether or not medals passing through the selector have been detected by the medal sensors 124 and 125 without being cheated by the process of step S24 described above (step S25).

  Then, when the passage of medals is detected without cheating, the main CPU 32 determines whether or not the value of the inserted number count area is the maximum value (step S26). This maximum value is “1” when the RB operating flag is on, and is “3” when the RB operating flag is off. When the main CPU 32 determines that the value of the inserted number count area is not the maximum value, the main CPU 32 adds 1 to the value of the inserted number count area (step S27). Next, the main CPU 32 stores “5” in the value of the effective line count area (step S28). The effective line count area is a storage area provided in the control RAM 34, and data for specifying the number of effective lines is stored in the storage area. Next, the main CPU 32 transmits a medal insertion command to the sub-control unit 60 (step S29). The medal insertion command includes data on the number of medals inserted into the game.

  On the other hand, when determining in step S25 that the value of the inserted number count area is the maximum value, the main CPU 32 adds “1” to the value of the credit count area (step S30). The credit count area is a storage area provided in the control RAM 34, and stores data for counting the number of medals credited to the slot machine 1. Next, after performing the process of step S29 or S30, or when no medal is detected in step S25, the main CPU 32 checks whether or not the BET switch has been operated by the player (step S31). Specifically, when one of the BET switches 11 and 12 is on, the type is specified, and the value stored in the inserted number count area is updated.

  Next, the main CPU 32 determines whether or not the value of the inserted number count area is “1” (step S32). If the main CPU 32 determines that the value of the inserted sheet count area is not “1”, it next determines whether or not the value of the inserted sheet count area is “3” (step S33). At this time, if the main CPU 32 determines that the value of the inserted number count area is not “3”, the process returns to step S24. On the other hand, when the main CPU 32 determines that the value of the inserted number count area is “1” in step S31 described above, or when the value of the inserted number count area is “3” in step S32. Then, it is determined whether or not the start switch 13 is ON (step S34). If the main CPU 32 determines that the start switch 13 is not ON, the process returns to step S24. If the main CPU 32 determines that the start switch 13 is ON, the medal passage is prohibited (step S35). Specifically, the above-described selector solenoid 122 is not driven until one game is completed, and medals inserted thereafter are discharged from the medal discharge port 16. When this process ends, the main CPU 32 ends the medal acceptance / start check process, and proceeds to step S4 of the game control process shown in FIG.

  Next, the contents of the medal detection process performed in step S24 of the above-described medal acceptance / start check process will be described with reference to the flowchart shown in FIG. First, the main CPU 32 determines whether or not the medal detection signal output from the first medal sensor 124 is ON (step S40). When the medal detection signal is turned on, the main CPU 32 determines whether or not the value of the flag F1 indicating that the medal inserted into the medal slot 10 is detected by the first medal sensor 124 is “0”. Is determined (step S41). Here, the value of the flag F1 is stored in a predetermined storage area of the control RAM 34 shown in FIG. 5. If the value is “0”, it means that the first medal sensor 124 has not detected a medal. In the case of “1”, it indicates that a medal is detected.

  When the value of the flag F1 is “0”, the main CPU 32 sets the value of the flag F1 stored in the control RAM 34 to “1” (step S42), and measures the time in the timer 40 shown in FIG. Start (step S43). Then, the main CPU 32 ends the medal detection process shown in FIG. 17, and proceeds to the process of step S25 of the medal acceptance / start check process shown in FIG. On the other hand, when the value of the flag F1 stored in the control RAM 34 is “1” in step S41, the main CPU 32 ends the medal detection process shown in FIG. 17 as it is, and the medal shown in FIG. The process proceeds to step S25 of the reception / start check process.

  Next, in the process of step S40, when the medal detection signal output from the first medal sensor 124 is OFF, the main CPU 32 turns on the medal detection signal output from the second medal sensor 125. It is determined whether or not (step S44). If the medal detection signal output from the second medal sensor 125 is ON, the main CPU 32 determines whether or not the value of the flag F1 stored in the control RAM 34 is “1”. Judgment is made (step S45). Here, when the value of the flag F1 stored in the control RAM 34 is “1”, the main CPU 32 instructs the timer 40 to end timing, and reads the time t1 measured by the timer 40 ( Step S46). Then, it is determined whether or not the measurement time t1 of the timer 40 is shorter than a predetermined time T (step S47). This time T is the time from when the first medal sensor 124 detects the medal to when the second medal sensor 125 detects the medal when the medal flows down the medal passage 102 in a normal state. It is the time set by going.

  If the time t1 measured by the timer 40 is shorter than the predetermined time T, the main CPU 32 sets the value of the flag F2 stored in the control RAM 34 to “1” (step S48). ), The medal detection process shown in FIG. 17 is terminated, and the process proceeds to the process of step S25 of the medal acceptance / start check process shown in FIG. Here, the initial value of the flag F2 is “0”, and the value of the flag is “1” means that the medal inserted from the medal insertion slot 10 is detected by the first medal sensor 124. After that, it means that the time is detected by the second medal sensor 125 and the time from detection by the first medal sensor 124 to detection by the second medal sensor 125 is normal.

  In contrast, first, in step S45 described above, when the value of the flag F1 is “0”, that is, the medal inserted from the medal slot 10 is detected by the first medal sensor 124. It is not detected by the second medal sensor 125. In this case, when the medal is inserted, the main CPU 32 considers that some sort of fraud has been performed, and transmits a specific sound output command to the sub-control unit 60 via the sub-control unit communication port 47 (step S49). In addition, when the time t1 measured by the timer 40 exceeds the predetermined time T in step S47 described above, the main CPU 32 regards that an illegal act has been performed when a medal is inserted. The process proceeds to step S49, and a specific sound output command is transmitted to the sub-control unit 60 via the sub-control unit communication port 47. The processing when the sub control unit 60 receives this specific sound output command will be described in detail later.

  Next, when the medal detection signal output from the second medal sensor 125 is OFF in step S44, the main CPU 32 determines whether or not the value of the flag F2 is “1” (step S50). . Here, when the value of the flag F2 is “0”, the main CPU 32 regards that no medal has been inserted into the medal insertion slot 10, and ends the medal detection process shown in FIG. 17 as it is. The process proceeds to step S25 of the medal acceptance / start check process shown in FIG. On the other hand, when the value of the flag F2 is “1”, the main CPU 32 determines that the medal inserted into the medal slot 10 has passed through the first medal sensor 124 and the second medal sensor 125. (Step S51), the values of the flags F1 and F2 stored in the control RAM 34 are reset to “0” (Step S52). Then, the medal detection process shown in FIG. 17 is terminated, and the process proceeds to step S25 of the medal acceptance / start check process shown in FIG.

  Next, the internal lottery process in step S5 of the game control process shown in FIG. 15 will be described with reference to the flowchart shown in FIG. First, the main CPU 32 sets a general gaming state internal lottery table (see FIG. 8A) as a lottery table used for internal lottery, and sets “7” as the number of comparisons (step S60). Next, the main CPU 32 determines whether or not the RB operation flag is on (step S61). When the main CPU 32 determines that the RB operating flag is on, the lottery table used for the internal lottery is changed to the internal lottery table for RB gaming state (see FIG. 8C), and the comparison count is “ 4 "(step S62). On the other hand, when the main CPU 32 determines in step S61 that the RB operating flag is not on, it determines whether or not the value of the RT game number count area is “0” (step S63). When the main CPU 32 determines that the value of the RT game number count area is not “0”, the lottery table used for the internal lottery is changed to the RT lottery table (see FIG. 8B) (step S64). ).

  After the process of step S64 or when determining that the value of the RT game number count area is “0” in step S63, the main CPU 32 sets bit 5 of the carryover combination storage area (see FIG. 11B) or It is determined whether “1” is stored in bit 6 (that is, whether “RB1” or “RB2” is internally winning) (step S65). If the main CPU 32 determines that “1” is stored in bit 5 or bit 6 of the carryover combination storage area, the main CPU 32 changes the number of comparisons to “5” (step S66). With this process, when the carryover combination is won internally, “RB1” or “RB2” is not repeatedly won. Next, after determining that “1” is not stored in either bit 5 or bit 6 in step S65 after the processing in step S62 or S66, the main CPU 32 sets the same value as the number of comparisons. The winning number is set (step S67).

  Next, the main CPU 32 refers to the internal lottery table selected by the process of step S60, step S62, or step S64, and is stored in the random number value storage area of the control RAM 34 by the process of step S4 of FIG. The lower limit value and the upper limit value corresponding to the random number value, the value stored in the inserted number count area, and the set winning number are compared (step S68). Then, the main CPU 32 determines whether or not the random number value stored in the random value storage area is not less than the lower limit value to be compared and not more than the upper limit value (step S69). If the main CPU 32 determines in step S69 that the random number value is greater than or equal to the lower limit value and less than or equal to the upper limit value, the winning number corresponding to the lower limit value and the upper limit value that are the comparison targets is set as the internal winning result. (Step S70). Next, the main CPU 32 determines whether or not “RB1” or “RB2” is won as a result of the internal lottery based on the internal winning combination determination table shown in FIG. 9 (step S71). When the main CPU 32 determines that the internal winning combination is “RB1” or “RB2”, the main CPU 32 stores data indicating “RB1” or “RB2” in the carryover combination storage area shown in FIG. Step S72).

  After the process of step S72 or when the main CPU 32 determines in step S71 that the internal winning combination is not “RB1” or “RB2”, the data representing the internal winning combination (“in the internal winning combination determination table of FIG. 9“ The logical sum of the value in the “Data” column) and the value stored in the carryover combination storage area is stored in the internal winning combination storage area (see FIG. 11A) (step S73). Next, after determining that the random number value stored in the random value storage area in step S <b> 73 or not in step S <b> 69 is not less than the lower limit value and not more than the upper limit value after comparison in step S <b> 69. “1” is subtracted from the number of times (step S74). Then, the main CPU 32 determines whether or not the number of comparisons is “0” (step S75). If it is determined that the number of comparisons is not “0”, the process returns to step S67. On the other hand, if it is determined that the number of comparisons is “0”, the logical sum of the value stored in the internal winning combination storage area and the value stored in the carryover combination storing area is stored in the internal winning combination storage area. (Step S76). When this process ends, the main CPU 32 ends the internal lottery process shown in FIG. 18, and proceeds to the process of step S6 shown in FIG.

  Next, the reel stop control process in step S9 of the game control process shown in FIG. 15 will be described with reference to the flowchart shown in FIG. First, the main CPU 32 determines whether or not a valid stop switch (that is, a stop switch among the stop switches 5L, 5C, and 5R that has not been pressed by the player after the reel has started rotating) has been pressed. Is determined (step S80). When the main CPU 32 determines that a valid stop button has not been pressed, it repeats the process of step S80.

  When the main CPU 32 determines that a valid stop switch has been pressed in step S80, the main CPU 32 identifies the stop switch for which the press operation has been performed and invalidates the corresponding stop switch (step S81). That is, after that, even if the corresponding stop switch is pressed, an identifier indicating that the operation is invalid is stored in the control RAM 34. Next, the main CPU 32 sets “5” as the number of checks (step S82). Then, the main CPU 32 searches for the symbol number having the highest priority within the range of the number of checks described above from the symbol number corresponding to the value stored in the symbol count area of the control RAM 34 (step S83). As a result, for example, from the symbol number corresponding to the value stored in the symbol count area, each symbol within the range of the number of checks is included in the internal symbol combination (that is, data stored in the internal symbol combination storage area). ) Is searched for whether there is a symbol that satisfies the symbol combination corresponding to.

  At this time, the symbol number having the highest priority order is determined based on the priority order determined in advance according to the symbol combination type (in other words, the internal winning combination type) relating to the provision of the privilege. Here, the symbol combination corresponding to “Replay” as the priority order 1 and the symbol combination corresponding to “RB1” and “RB2” as the priority order 2 are set to the priority order “Small 1” to “Small 4”. Assume that a symbol combination corresponding to each is determined. In addition, when there are a plurality of symbols having the highest priority within the range of the number of checks described above, a predetermined priority (for example, the number of sliding frames “0” → “1” from among the number of sliding symbols that can be determined). Any one of them may be determined by “2” → “3” → “4”).

  Next, the main CPU 32 determines the number of sliding pieces based on the search result obtained by the process of step S83 (step S84). That is, when the stop switch is operated, the amount of movement from the symbol number (hereinafter referred to as “stop start symbol number”) located at the middle line L3 to the determined symbol number is determined as the number of sliding symbols. Next, the main CPU 32 stores the scheduled stop position based on the number of sliding symbols and the value stored in the symbol count area (step S85). That is, the symbol number of the value obtained by adding the number of sliding symbols to the stop start symbol number is determined as the scheduled symbol number to be stopped. When the scheduled stop symbol number is stored, in an interrupt process (see FIG. 22) described later, a process of stopping the rotation of the reel is performed based on the scheduled stop symbol number. Note that the number of sliding symbols and the scheduled symbol number to be stopped are in an equivalent relationship because if one is determined, the other is also determined.

  Next, the main CPU 32 transmits a reel stop command to the sub-control unit 60 (step S86). The reel stop command includes data such as the type of reel whose stop is controlled. Then, the main CPU 32 determines whether or not there is a stop button for which the pressing operation is effective (step S87). As a result, when the main CPU 32 determines that there are still stop buttons for which the pressing operation is effective, the process returns to step S80, and when it is determined that there are no stop buttons for which the pressing operation is effective, FIG. The reel stop control process is terminated, and the process proceeds to step S10 in FIG.

  As described above, in the slot machine 1, within a predetermined range from the stop start symbol number, symbol combinations corresponding to internal winning combinations (including “losing” in this case) as much as possible stop along the active line. It is controlled. In addition, when an internal winning combination excluding “losing” is determined, if a symbol constituting the symbol combination corresponding to the internal winning combination does not exist within the predetermined range described above, The symbol combination that is “lost” is controlled to stop along the active line. This state is referred to as “missing”. In this case, the data stored in the internal winning combination storing area in the control RAM 34 does not match the data stored in the established winning combination storing area. Here, as can be seen from the symbol row of each reel shown in FIG. 2, the “Plum” symbol PL is the other symbol arranged between the two “Plum” symbols PL in any reel. Since the number of the game is 4 or less, if the internal winning combination is “Replay”, no matter what timing the player operates the stop switch, the “Plum” symbol PL will always be along the active line. They are all stopped and displayed. For the same reason, even if the internal winning combination is “Small 3”, the “Bell” symbols BE are always stopped and displayed along the active line.

  On the other hand, for example, the “watermelon” symbol WM has a portion where the number of other symbols arranged between two “plum” symbols PL is 5 or more in each reel. Even if “small role 4” is determined, there is a possibility that the player may miss it depending on the operation timing of the stop switch of the player. For the same reason, “small role 1” (corresponding symbol combination: red cherry-ANY-ANY), “small role 2” (corresponding symbol combination: peach cherry-ANY-ANY), “RB1” (corresponding symbol combination: Blue 7-Blue 7-Blue 7) and "RB2" (corresponding symbol combination: red 7-red 7-red 7) may be missed.

  Next, the bonus end check process in step S14 of the game control process shown in FIG. 15 will be described with reference to the flowchart shown in FIG. First, the main CPU 32 determines whether or not any small combination has been established (step S90). That is, whether or not any of the values of bit 0 to bit 3 in the established combination storage area provided in the control RAM 34 is “1” (from “small role 1” to “small role 4”). It is determined whether or not any of them is established. When the main CPU 32 determines that any one of “Small 1” to “Small 4” has been established, the main CPU 32 subtracts “1” from the value of the winning count count area provided in the control RAM 34 ( Step S91). Next, the main CPU 32 determines whether or not the value of the winning count count area is “0” (step S92). When it is determined that the value of the winning count count area is not “0”, or when it is determined in step S90 that none of “small role 1” to “small role 4” is established, "1" is subtracted from the value of the possible count area (step S93).

  Next, the main CPU 32 determines whether or not the value of the possible game count area is “0” (step S94). If the main CPU 32 determines that the value of the possible game count area is not “0”, the main CPU 32 ends the bonus end check process and proceeds to the process of step S15 in FIG. On the other hand, when the main CPU 32 determines that the value of the possible game count area is “0”, or when the value of the possible win count area is “0” in step S92, the RB An end-time process is performed (step S95). Specifically, the data stored in the operating flag storage area (see FIG. 11C) of the control RAM 34 is cleared, and the values of the possible winning count area and the possible gaming count area are cleared. Next, the main CPU 32 stores a value “1000” (decimal number) in the RT game number count area provided in the control RAM 34 (step S96). Then, the main CPU 32 transmits a bonus end command to the sub-control unit 60 (step S97), and ends the bonus end check process shown in FIG.

  Next, the bonus operation check process in step S16 of the game control process shown in FIG. 15 will be described with reference to the flowchart shown in FIG. First, the main CPU 32 determines whether or not the established winning combination is “RB1” or “RB2” (step S100). When the main CPU 32 determines that the established winning combination is “RB1” or “RB2”, the main CPU 32 performs RB operation processing based on the bonus operation table shown in FIG. 10 (step S101). Next, the main CPU 32 clears the carryover combination storage area shown in FIG. 11B and also clears the value of the RT game number count area provided in the control RAM 34 (step S102). The main CPU 32 transmits a bonus start command to the sub-control unit 60 (step S103), ends the bonus operation check process shown in FIG. 21, and proceeds to step S2 shown in FIG.

  On the other hand, when the main CPU 32 determines that the winning combination established in step S60 is not “RB1” or “RB2”, it determines whether “replay” is established (step S104). If the main CPU 32 determines that “replay” has been established, the control RAM 34 stores information indicating this and the number of medals inserted in the current game (step S105). As a result, when the next game is started, the number of medals inserted in the current game is automatically inserted in the medal acceptance / start check process of step S3 shown in FIG. When the process of step S105 is completed, the bonus operation check process shown in FIG. 21 is terminated, and the process proceeds to step S2 shown in FIG. Furthermore, if the main CPU 32 determines in step S104 that “replay” has not been established, it next determines whether or not “small role 1” has been established (step S106). If the main CPU 32 determines that “small role 1” has not been established, the bonus operation check process shown in FIG. 21 ends, and the process proceeds to step S2 shown in FIG. On the other hand, if the main CPU 32 determines that “small role 1” has been established, the value of the RT game number count area in the control RAM 34 is cleared (step S107), and then the bonus operation check process shown in FIG. And the process proceeds to step S2 shown in FIG.

  Next, with reference to the flowchart shown in FIG. 22, the flow of the interrupt process executed by the main CPU 32 in accordance with the interrupt signal periodically output from the frequency divider 37 shown in FIG. Here, it is assumed that the main CPU 32 executes the interrupt process of FIG. 22 every 1.1173 milliseconds. First, after saving the register (step S110), the main CPU 32 performs an input port check process (step S111). As the input port check process, the main CPU 32 checks the input of signals from the switches shown in FIG. Next, the main CPU 32 performs a reel control process (step S112). With this process, when the reel rotation request is made, the reels 4L, 4C, and 4R start to rotate, and thereafter, the rotation at a constant speed is maintained. Further, when the scheduled symbol number is stored, when the value stored in the symbol count area of the corresponding reel matches the value of the scheduled symbol number, the reel is decelerated so that the corresponding reel stops. And stop control is performed. Thus, for example, if the value of the symbol count area is “0” and the symbol number to be stopped is “4”, the corresponding reel rotates when the value of the symbol count area becomes “4”. Stopped.

  Next, the main CPU 32 performs a lamp driving process (step S113), and updates the numerical values displayed on the LEDs 9a to 9f and the 7-segment display 8 constituting the game information display unit 7. Then, the main CPU 32 performs a vibration detection process for determining whether or not an impact is applied to the front door 2a by the vibration detectors 20A and 20B shown in FIGS. 1 and 4 (step S114). The contents of this vibration detection process will be described in detail later. When the vibration detection process in step S114 is completed, the main CPU 32 completes the interrupt process shown in FIG. 22 after restoring the register (step S115).

  Next, the contents of the vibration detection process performed in step S114 of the interrupt process described above will be described with reference to the flowchart shown in FIG. First, the main CPU 32 determines whether or not the vibration detector 20A or 20B is in an OFF state (step S120). If the vibration detector 20A or 20B is in the OFF state, the determination result is YES, and the main CPU 32 determines whether or not the value of the variable CNT stored in the predetermined storage area of the control RAM 34 is “0”. Is determined (step S121). If the value of the variable CNT is “0”, the determination result in step S121 is YES, and the main CPU 32 instructs the timer 40 (see FIG. 5) to start measuring time t2 (step S122). Thus, the timer 40 starts measuring time t2. Next, the main CPU 32 adds “1” to the value of the variable CNT stored in the control RAM 34 and stores it in the control RAM 34 (step S123). If the value of the variable CNT stored in the control RAM 34 is not “0” in step S121, the determination result in step S121 is NO, and the process proceeds to step S123 without performing step S122. “1” is added to the value of.

  When the process of step S123 is completed, the main CPU 32 determines whether or not the time t2 counted by the timer 40 has exceeded 2 seconds (step S124). If the time t2 does not exceed 2 seconds, the determination result of step S124 is NO, the vibration detection process shown in FIG. 23 is terminated, and the process proceeds to the process of step S115 of the interrupt process shown in FIG. On the other hand, if the time t2 is longer than 2 seconds, the determination result in step S124 is YES, and the main CPU 32 instructs the timer 40 to end timing, and the time that has been counted until then. Is reset (step S125). Then, the main CPU 32 determines whether or not the value of the variable CNT stored in the control RAM 34 exceeds “3” (step S126). That is, it is determined whether or not the total number of times that the vibration detector 20A or 20B has been turned off has exceeded three times within 2 seconds after the vibration detector 20A or 20B is first turned off. If the value of the variable CNT exceeds “3”, the determination result in step S126 is YES, and the main CPU 32 indicates that the door opening / closing switch 21 shown in FIG. 1 is OFF (that is, the front door). It is determined whether or not 2a is closed (step S127).

  If the door opening / closing switch 21 is OFF, the determination result in step S127 is YES, and the main CPU 32 regards the front door 2a as being subjected to an external impact, and the sub control unit communication port 47. The specific sound output command is transmitted to the sub-control unit 60 via (step S128). The processing when the sub control unit 60 receives this specific sound output command will be described in detail later. Then, after resetting the value of CNT stored in the control RAM 34 to “0” (step S129), the main CPU 32 ends the vibration detection process shown in FIG. 23, and performs the interrupt process steps shown in FIG. The process proceeds to S115.

  If the value of the variable CNT does not exceed “3” in step S126 described above, or if the door opening / closing switch 21 is turned on in step S127, the determination result is NO and the main CPU 32 Then, the process directly proceeds to the process of step S129, the value of the CNT stored in the control RAM 34 is reset to “0”, the vibration detection process shown in FIG. 23 is terminated, and the interrupt process shown in FIG. The process proceeds to step S115. In step S120 described above, if neither the vibration detector 20A or 20B is in the OFF state, the main CPU 32 determines whether or not the timer 40 is measuring time t2 (step S130). . If the timer 40 is measuring time t2, the determination result in step S130 is YES, and the main CPU 32 ends the vibration detection process shown in FIG. 23 as it is, and the interrupt process shown in FIG. The process proceeds to step S115. On the other hand, if the timer 40 is not counting the time t2, the determination result in step S130 is NO, and the main CPU 32 proceeds to the process in step S129 and stores the CNT stored in the control RAM 34. After the value is reset to “0”, the vibration detection process shown in FIG. 23 is terminated, and the process proceeds to the process of step S115 of the interrupt process shown in FIG.

  By the vibration detection process of FIG. 23 described above, the main CPU 32 first turns off the vibration detector 20A or 20B in a state where the front door 2a is closed (that is, the determination result in step S127 is YES). If it is detected that the vehicle has been turned off four times or more in 2 seconds from the beginning, it is determined that an impact has been applied to the front door 1a. On the other hand, when the front door 2a is open (that is, the determination result of step S127 is NO), four times or more in 2 seconds after the vibration detector 20A or 20B is initially turned OFF, Even if it is detected that the vehicle is in the OFF state, it is not determined that an impact has been applied to the front door 1a. This is to prevent a specific sound from being output when, for example, an attendant at a game hall opens the front door 1a and performs operations such as supplying medals to the hopper 51.

  Next, the control performed by the sub CPU 61 of the sub control unit 60 will be described with reference to the flowcharts shown in FIGS. First, input processing performed by the sub CPU 61 will be described with reference to FIG.

  First, the sub CPU 61 determines whether or not a command transmitted from the main control unit 30 has been received (step S140). When no command is received from the main control unit 30, the sub CPU 61 determines whether or not an H level digital signal is output from the comparator 69 shown in FIG. 13, that is, a specific sound is output from the microphones 6L and 6R. It is determined whether or not it has been input (step S141). If the H level digital signal is not output from the comparator 69, the sub CPU 61 returns to the process of step S140. Then, the processes in steps S140 and S141 are repeatedly executed until a command is received from the main control unit 30 or a specific sound is input.

  In the process of step S140 described above, when any command is received from the main control unit 30, the sub CPU 61 recognizes the type of the received command (step S142). Then, the sub CPU 61 determines whether or not the recognized command is different from the previously received command (step S143), and if it is the same command as the previously received command, the process of step S140 Return to. On the other hand, if it is determined that a command different from the previously received command has been received, the sub CPU 61 stores the received command in the message queue (step S144), and then returns to the process of step S140.

  Further, in the above-described processing of step S141, when an H level digital signal is output from the comparator 69, the sub CPU 61 displays image data and alarm sound of the fraudulent notification screen stored in the data storage area of the control ROM 62. And data for blinking the upper lamp 19 in a specific pattern are read out and output to the image control unit 65, the musical tone control unit 66, and the lamp driver 67 for a predetermined time, respectively (step) S145). As a result, a fraudulent notification screen (for example, a character message indicating that a fraudulent act is being performed in another slot machine such as “fraud is occurring!”) Is displayed on the liquid crystal display device 3 for a certain period of time. The alarm sound is output from the speakers 18L, 18R, 18B for a certain time, and the upper lamp 19 blinks in a specific pattern for a certain time. When the process of step S145 is completed, the sub CPU 61 returns to the process of step S140, and repeats the processes of steps S140 and S141 until a command is received from the main control unit 30 or a specific sound is input again. Execute.

  Next, the effect registration process performed by the sub CPU 61 will be described with reference to the flowchart shown in FIG. First, the sub CPU 61 extracts the command stored in step S144 of the input process shown in FIG. 24 from the message queue (step S150). Next, the sub CPU 61 determines whether there is a command (step S151). When it is determined that there is a command, the sub CPU 61 copies game information from the command to the work RAM 63 (step S152). As a result, if the command received from the main control unit 30 includes information indicating the type of the internal winning combination, the information is copied to the work RAM 63. Then, the sub CPU 61 performs effect content determination processing which will be described in detail later (step S153). In this process, based on the type of the received command, the content of the effect is determined and the progress of the effect based on the determined effect content is performed.

  Next, after performing the effect content determination process in step S153, or when there is no command in the message queue in step S151, the sub CPU 61 sets the effect content most recently determined in the effect content determination process in step S143. Based on this, animation data for performing an effect by an image displayed on the liquid crystal display device 3 is registered (step S154). Further, the sub CPU 61 emits the command for designating musical sound data output from the speakers 18L, 18R, and 18B and the upper lamp 19 based on the effect content most recently determined in the effect content determination process in step S153. A command for designating a light emission pattern is registered (step S155). When this process ends, the sub CPU 61 returns to the process of step S150.

  Next, with reference to the flowchart shown in FIG. 26, the content of the effect content determination process performed by step S153 of the effect registration process shown in FIG. 25 is demonstrated. First, the sub CPU 61 determines whether or not the command extracted in step S152 in FIG. 25 is a start command (see step S6 in FIG. 15) (step S160). If it is determined that the command is a start command, the sub CPU 61 performs an effect lottery process, which will be described in detail later (step S161). When this process ends, the sub CPU 61 ends the effect content determination process shown in FIG. 26, and proceeds to the process of step S154 shown in FIG. On the other hand, when the sub CPU 61 determines in step S160 described above that the command is not a start command, the sub CPU 61 next determines whether or not the command extracted in step S152 in FIG. 25 is a reel stop command. Judgment is made (step S162).

  Here, if it is determined that the command is a reel stop command, the sub CPU 61 proceeds the presentation according to the animation data and the specified command registered in steps S154 and S155 of FIG. 25 described above based on the reel type and the like (step S163). ). Thereby, for example, detection of the first stop operation (stop switch operation first performed by the player after the reel starts rotating), second stop operation (player 2 after the reel starts rotating). And the third stop operation (the last stop switch operation performed by the player after the reel starts to rotate) is detected. . When this process ends, the sub CPU 61 ends the effect content determination process shown in FIG. 26, and proceeds to the process of step S154 shown in FIG.

  Next, when the sub CPU 61 determines in step S162 described above that the command is not a reel stop command, the sub CPU 61 determines that the command extracted in step S152 in FIG. It is determined whether or not there is (step S164). Here, when the sub CPU 61 determines that it is a winning combination command, the sub CPU 61 advances the presentation based on the type of winning combination (step S165). That is, an effect is produced when the rotation of all the reels 4L, 4C, 4R is stopped according to the animation data registered in steps S154 and S155 of FIG. 25 and the specified command. When this process ends, the sub CPU 61 ends the effect content determination process shown in FIG. 26, and proceeds to the process of step S154 shown in FIG.

  Next, when the sub CPU 61 determines in step S164 described above that the command is not a winning combination command, the sub CPU 61 determines that the command extracted in step S152 of FIG. 25 is a bonus start command (see FIG. 21, step S103). It is determined whether or not there is (step S166). If the sub CPU 61 determines that the command is a bonus start command, the sub CPU 61 sets effect data corresponding to the RB game (step S167). Then, the sub CPU 61 updates the data indicating the current gaming state stored in the work RAM 63 to data indicating the RB gaming state (step S168). When this process ends, the sub CPU 61 ends the effect content determination process shown in FIG. 26, and proceeds to the process of step S154 shown in FIG.

  Next, when the sub CPU 61 determines in step S166 described above that the command is not a bonus start command, the sub CPU 61 determines that the command extracted in step S152 in FIG. 25 is a bonus end command (see FIG. 20, step S97). It is determined whether or not there is (step S169). Here, when the sub CPU 61 determines that it is a bonus end command, the sub CPU 61 sets effect data to be executed at the end of the RB game (step S170). Then, the sub CPU 61 updates the data indicating the current gaming state stored in the work RAM 63 to data indicating the general gaming state (step S171). When this process ends, the sub CPU 61 ends the effect content determination process shown in FIG. 26, and proceeds to the process of step S154 shown in FIG.

  Next, when the sub CPU 61 determines in step S169 described above that the command is not a bonus end command, the sub CPU 61 determines that the command extracted in step S152 in FIG. 25 is the specific sound output command (FIG. 17, step S49 and FIG. 23, see step S128) (step S172). If the sub CPU 61 determines that the command is a specific sound output command, the sub CPU 61 reads out audio data corresponding to the specific sound from the control ROM 62 and outputs it to the D / A converter 661 (step S173). Then, the effect content determination process shown in FIG. 26 is terminated, and the process proceeds to the process of step S154 shown in FIG. If the sub CPU 61 determines that the command is not a bonus end command in step S172 described above, the effect content determination process shown in FIG. Then, the process proceeds to step S154 shown in FIG.

  Next, the contents of the effect lottery process performed in step S161 of the effect content determination process shown in FIG. 26 will be described with reference to the flowchart shown in FIG. First, the sub CPU 61 updates various game information based on the contents of the start command extracted from the message queue (step S180). Next, the sub CPU 61 determines whether or not the current gaming state stored in the work RAM 63 is the RB gaming state (step S181). If the sub CPU 61 determines that it is in the RB gaming state, it performs lottery processing for determining the content of the effect to be executed during the RB game operation (step S182), and ends the effect lottery processing in FIG. Then, the process proceeds to step S154 in FIG.

  On the other hand, when the sub CPU 61 determines that the current gaming state is not the RB gaming state in the process of step S181 described above, the type of the winning combination is determined by referring to the content of the received start command. Then, based on the random number lottery result based on the random number generated by the sub CPU 61, the contents of the effect to be executed are determined (step 183), the effect lottery process of FIG. 27 is terminated, and the process proceeds to the process of step S154 of FIG. Transition.

  As described above, in the slot machine 1, when a game is attempted without inserting a regular medal (when the determination result in FIG. 17, step S45 or S47 is NO), that is, given to the player. Specific sound output command is transmitted from the main control unit 30 to the sub-control unit 60 (step S49 in FIG. 17). When the sub control unit 60 receives this command (FIG. 26, the determination result in step S172 is YES), the audio data corresponding to the specific sound is read from the control ROM 62 and output to the D / A converter 661 ( As a result, the specific sound is output from the speakers 18L, 18R, and 18B.

  Further, when an impact is applied to the front door 2a from the outside and vibration due to the impact is detected by the vibration detector 20A or 20B (the determination result in FIG. 23, steps S126 and S127 is YES), the slot machine 1 is damaged. As a result, a specific sound output command is transmitted from the main control unit 30 to the sub-control unit 60 (step S128 in FIG. 23). As a result, the sub-control unit 60 outputs specific sounds from the speakers 18L, 18R, and 18B (FIG. 26, steps S172 and S173).

  The specific sound output from the speakers 18L, 18R, and 18B is captured by the microphones 6L and 6R and converted into an electrical signal. The electrical signal passes through the band-pass filter 68. As a result, the comparator 69 outputs an H level signal. When the digital signal is output, the determination result in step S141 in FIG. 24 is YES, and the fraudulent occurrence notification screen is displayed on the liquid crystal display device 3 for a certain period of time, and an alarm sound is output from the speakers 18L, 18R, and 18B. Then, the upper lamp 19 blinks in a specific pattern to notify that an illegal act has been performed (FIG. 24, step S145).

  As described above, the main CPU 32 that performs the processes of steps S45 and S47 in FIG. 17 and the processes of steps S126 and S127 in FIG. 23 corresponds to the fraud detection means. Also, the sub CPU 61 that performs the processes of steps S172 and S173 in FIG. 26 corresponds to a sound control unit. The band-pass filter 68, the comparator 69, and the sub CPU 61 that performs the process of step S141 in FIG. 24 correspond to a specific sound determination unit. Further, the liquid crystal display device 3, the speakers 18L, 18R, 18B, and the upper lamp 19 correspond to notification means.

  As described above, according to the slot machine 1 in the present embodiment, when an illegal act is detected, a specific sound is output from the speaker, and the specific sound is converted into an electric signal by the microphone and is determined to be the specific sound. When it is done, it is informed that an illegal act has been performed by sound, light, and an image. As a result, when an illegal act is performed in the slot machine 1, the fact is notified in the other slot machines 1 installed around the slot machine 1. It is possible to notify that an illegal act is being performed. Therefore, it can be expected that the attention of other players can be attracted more than the conventional gaming machine, and the deterrent effect can be increased. In addition, it is not necessary to connect the gaming machines with a cable or the like in order to transmit the fact that the illegal act has been performed to other gaming machines. The work at the time of new establishment or replacement can be facilitated.

  In the slot machine 1 described above, an illegal act related to medal insertion is detected as an illegal act. However, the type of the illegal act to be detected is not limited to this. It is also possible to detect an illegal act performed by generating the game, an act of improperly opening the game door 2a and attaching an unauthorized device. Further, in the slot machine 1 described above, the same specific sound is generated when an illegal act relating to the insertion of a medal is detected and when an impact is applied to the front door 2a. In each case, for example, A specific sound having a different frequency may be generated, and notification according to the type of the specific sound may be performed. In order to realize this, for example, a plurality of band pass filters corresponding to the frequency of each specific sound (that is, allowing only the frequency of each specific sound to pass) are provided, and each band pass filter outputs a predetermined level. In this case, it may be recognized that a specific sound corresponding to the bandpass filter has been generated.
