The present invention relates to a gaming machine.
2. Description of Related Art
A known gaming machine displays scrolling symbols on a display provided to a front of a cabinet when a player inserts a game medium such as a coin or paper money into an insertion slot and presses a spin button. Each symbol automatically stops thereafter.
Such gaming machine pays out a predetermined number of game media when the symbols displayed on a winning line form a predetermined combination, as disclosed in U.S. Pat. No. 6,604,999B2 (which was published as U.S. Patent Publication No. 2002065124A1, for example).
The exterior of a gaming machine in general is mostly made of a material which is easily electrostatically charged. In addition, since the exterior is most likely decorated, players often touch the exterior. Thus, the exterior of the gaming machine is prone to be electrostatically charged. The static electricity accumulated in the exterior can cause various problems such as irritating a player who has touched the exterior, and damaging the circuit board inside.
An object of the present invention is to provide a gaming machine which controls the occurrence of problems caused by accumulated static electricity.
A gaming machine for achieving the above object according to an embodiment of the present invention includes: a cabinet; an emission control unit provided to the cabinet, the emission control unit having a light emitting portion and causing the light emitting portion to light; an exterior member which is provided to a position surrounding the light emitting portion, and transmits light emitted by the light emitting portion to outside; a conductive sheet which is provided to a position interposing between the exterior member and the emission control unit; a ground unit which grounds the conductive sheet; and a controller which runs a game.
According to the structure, a conductive sheet is provided to a position interposing between the exterior member and the emission control unit. Thus, electricity accumulated to the exterior member is absorbed by the conductive sheet grounded via the ground member while being transmitted to the emission control unit. This prevents the electricity from reaching the emission control unit. Thus, this is effective for preventing damage to the emission control unit caused by electricity accumulated to the exterior member reaching the emission control unit.
Further, if the exterior member is made of a material having electric propensity, the possibility of damaging the emission control unit due to accumulated static electricity in the exterior member increases. However, damage to the emission control unit can be effectively avoided with the conductive sheet.
Furthermore, the exterior member does not accumulate static electricity if it is in contact with the conductive sheet. This surely prevents damage to the emission control unit caused by conduction of static electricity to the emission control unit, as well as prevents players from feeling electrostatic shocks even if the players touch the exterior. Thus, electrostatic shocks which irritate players are prevented. Thus, this prevents possible inconvenience to both the gaming machine and players.
The following describes an embodiment of a gaming machine with reference to figures.
As illustrated in
The “arranging” in this specification means a state where the symbols can be visually observed by a player. That is, the wording means a state where the symbols are displayed in the arrangement areas 150, in
The terminal display 101 may have a mechanical structure adopting a reel device which rotates a reel to arrange the symbols. Alternatively, the terminal display 101 may have an electrical structure in which a video reel is displayed as an image and symbols on a video reel are arranged in the form of an image. Further, the terminal display 101 may adopt a combination of the mechanical structure (reel) and the electrical structure (video reel). Examples of the electrical structure include a liquid crystal display device, a CRT (cathode-ray tube), a plasma display device, or the like. Further, the number of arrangement areas 150 is not limited. A specific structure of the terminal display 101 will be detailed later.
A bonus payout indicator 300 illustrated in
Paths 401 are realized by arrays of light emitting portions 403 forming a channel connecting a position 402, corresponding to each gaming terminal 10, to the bonus payout indicator 300. In this manner, the paths 401 are provided to correspond to the gaming terminals 10.
The light emitting portions 403 are realized by LEDs (light-emitting diodes), and are capable of emitting light in different colors. The light emitting portions 403 are lighted when activated. The light emitting portions 403 are controlled to be activated one after another, from the position 402, corresponding to each gaming terminal 10, to the bonus payout indicator 300.
The light emitting portions 403 are not limited to LEDs as long as light is emitted. The activation state is not limited to a lighting state and may be a flashing state. The light emitting portions 403 may be adapted to emit only one color; however, it is preferable that the light emitting portions 403 be capable of emitting more than one color to provide a wide variety of effects.
(Running Base Game)
The following specifically describes an example of a base game in the gaming machine 1. Note that the following example deals with a case where the terminal display 101 adopts a video reel and arranges symbols on the video reel.
As illustrated in
The terminal display 101 variably displays symbols when a base game is started in the gaming terminal 10. When this variable-displaying of symbols stops, symbols are rearranged in the arrangement areas 150. Then, when a winning is met according to a relation among the rearranged symbols, a payout according to this winning is awarded.
Note that, part of the bet made by the player is accumulated in the form of a jackpot value, every time a base game is started. The jackpot value so accumulated is displayed in the bonus payout indicator 300, as illustrated in
(Running Bonus Game)
The following specifically describes an example of a bonus game in the gaming machine 1.
A bonus game is started when the accumulated jackpot value exceeds a certain value. In a bonus game, the symbols are rearranged in the matrix in each gaming terminal 10. When a predetermined winning is met by the rearrangement of the symbols, the light emitting portions 403 turn active in random numbers, in the path 401 corresponding to the gaming terminal 10 in which the winning has occurred. This operation is repeated until the light emitting portions 403 in any of the paths 401 are activated up to the bonus payout indicator 300.
When the light emitting portions 403 are activated all the way up to the bonus payout indicator 300, a jackpot is awarded as a bonus payout in the gaming terminal 10 corresponding to the path 401 in which the light emitting portions 403 turned active up to the bonus payout indicator 300.
(Symbol, Combination, or the Like)
The terminal display 101 has the matrix including symbol columns each having twenty two symbols, as illustrated in
Of the symbols in the symbol columns, the display windows 151 to 155 each displays (arranges) three successive symbols. The symbols arranged in the upper stage, the central stage, and the lower stage form a symbol matrix having five columns and three rows. When a BET button and a start button are sequentially pressed in this order to start a game, symbols constituting the symbol matrix start to scroll. This scrolling of the symbols stops (rearrangement) after a predetermined period from the beginning of the scrolling.
Further, for each symbol, a predetermined scatter symbol is determined in advance. Scatter symbols are such symbols that a player is put in an advantageous position when a predetermined number or more of them are displayed in the matrix. For example, the advantages include: a state where coins corresponding to the scatter symbols are paid out, a state where the number of coins to be paid out is added to a credit, a state where a bonus game is started.
Here, a bonus game is a gaming state which provides a larger advantage than a base game. In this embodiment, the bonus game is a jackpot game. No particular limitation is put on the bonus game, as long as it is a gaming state advantageous to the player, that is, it is more advantageous than the base game. For example, the bonus game may include a state where more game media are obtainable than in the base game, a state where a game medium is obtainable with higher probability than in the base game, a state where a game medium is less consumed than in the base game, and the like. Specifically, a free game, a second game, a feature game, and the like may be mentioned as examples of the bonus game.
(Mechanical Structure of Gaming Machine 1)
Next, the following describes a specific example of mechanical and electrical structures of the gaming machine 1 thus structured.
A gaming machine 1 is placed in a gaming facility such as a casino. This gaming machine 1 runs a unit game which involves a game medium. The game medium is a coin, bill, or a value in the form of electronic information. However, the game medium in the present invention is not particularly limited. For example, a medal, token, electronic money, ticket or the like are also possible. Further, the ticket is not particularly limited and may be a later-described ticket with a barcode or the like ticket.
As illustrated in
As illustrated in
The present embodiment deals with a case where the lower image display panel 16 electrically displays symbols arranged in five rows/three columns. However, the present invention is not limited to this.
The lower image display panel 16 displays a single activated payline L. Note that the number of pay lines L may be two or more. When the number of pay lines L is two or more, the number of pay lines L activated may be determined according to a predetermined condition, such as the number of coins placed as a BET.
Note that the lower image display panel 16 may have a credit value indicator and a payout value indicator. The credit value indicator displays a total value (hereinafter also referred to as total credit value) which a gaming terminal 10 can pay out to a player. When symbols stopped along a pay line L form a winning combination, the payout value indicator displays the number of coins to be paid out.
Further, scatter symbols may be adopted, and the number of coins to be paid out may be determined, according to the number of scatter symbols displayed on the matrix. Note that the pay line L does not necessarily have to be displayed.
Below the lower image display panel 16 provided are a control panel 20, a coin insertion slot 21, and a bill validator 22. The control panel 20 is provided with various buttons 23 to 27. These buttons 23 to 27 allow a player to input instructions related to a game played by the player. Through the coin insertion slot 21, a coin is received in the cabinet 11.
The control panel 20 includes: a spin button 23, a change button 24, a cashout button 25, a 1-BET button 26, and a maximum BET button 27. The spin button 23 is for inputting an instruction to start symbol scrolling. The change button 24 is used to ask a staff person in the gaming facility for exchange of money. The cash out button 25 is for inputting an instruction to pay out coins corresponding to the total credit-value into the coin tray 18.
The 1-BET button 26 is used for betting one coin out of those corresponding to the total credit value. The maximum BET button 27 is used for betting, out of those corresponding to the total credit value, a maximum number of coins (e.g., fifty coins) which can be bet in one game.
The bill validator 22 validates whether bill is genuine or not and receives the genuine bill into the cabinet 11. Note that the bill validator 22 is capable of reading a barcode attached to a later-mentioned ticket 39 having a barcode (hereinafter simply referred to as ticket 39). When the bill validator 22 reads the ticket 39, it outputs to the main CPU 41 a read signal representing information having read from the barcode.
On the lower front surface of the main door 13, that is, below the control panel 20, a belly glass 34 is provided. On the belly glass 34, a character of a gaming terminal 10 or the like is drawn. On the front surface of top box 12 is provided an upper image display panel 33. The upper image display panel 33 has a liquid crystal panel and displays an effect image, introduction to the game, rules of the game, or the like.
Further, the top box 12 has a speaker 29 for performing an audio output. Below the upper image display panel 33 are provided a ticket printer 35, a card reader 36, a data displayer 37, and a keypad 38. The ticket printer 35 prints, onto a ticket, a barcode having encoded data containing credit-value, date and time, identification number of a gaming terminal 10 or the like, thereby issuing a ticket 39 having a barcode attached thereto. A player can play a game in another gaming terminal 10 with the ticket 39 having the barcode, or exchange the ticket 39 having the barcode with paper money or the like at a change booth or the like of the game arcade.
The card reader 36 reads/writes data from/into a smart card. The smart card is carried by a player, and stores therein data for identifying the player, data relating to a history of games played by the player, or the like.
The data displayer 37 includes a fluorescent display or the like, and displays the data read by the card reader 36 and the data input by the player through the keypad 38. The keypad 38 is for entering instructions or data relating to issuing of a ticket or the like.
Provided to the left and right of the upper image display panel 33 on the front surface of the top box 12 are emission devices 70 (70L and 70R), respectively. Each of the emission devices 70 includes light emitting portions 74a. Each of the emission devices 70 lights the light emitting portions 74a to provide an effect unrelated to the base game.
The emission control unit 74 is a circuit board of a rectangular plate. On a front surface of the substrate are light emitting portions 74a (LEDs) arranged in a matrix. Independently of the terminal controller 100 and the center controller 200 which run each game, the emission control unit 74 randomly selects an emission pattern from a not-illustrated ROM storing emission patterns, and lights the light emitting portions 74a in the selected emission pattern. Note that the emission control unit 74 may light the light emitting portions 74a based on a command by the controllers which run each game.
Provided to the front and sides of the emission control unit 74 is the exterior member 72 made of plastic. Plastic is a material having electrostatic propensity. The exterior member 72 has a front surface and two side surfaces. The front surface of the exterior member 72 slightly curves in the longitudinal direction from both ends of the longitudinal direction to the center portion, so that the center portion of the front surface projects. Each of the side surfaces of the exterior member 72 is provided towards the back from both ends of the front surface in the transverse direction. The exterior member 72 is provided to a position surrounding the light emitting portions 74a. With the front and side surfaces, the exterior member 72 shields the light emitting portions 74a from outside. On the front surface of the exterior member 72 are through holes 72a arranged in a matrix. The through holes 72a are formed in front of the light emitting portions 74a so as to allow light emitted from the light emitting portions 74a to be transmitted to the outside when the exterior member 72 covers the emission control unit 74.
Interposing between the exterior member 72 and the emission control unit 74 is the rectangular plate conductive sheet 73. The conductive sheet 73 has conductive holes 73a formed thereon in a matrix, penetrating the conductive sheet 73 in the board-thickness direction. The conductive holes 73 correspond to the through holes 72a of the exterior member 72, and the light emitting portions 74a of the emission control unit 74. The light emitting portions 74a of the emission control unit 74 are inserted into the conductive holes 73a and the through holes 72a.
Further, the conductive sheet 73 has substantially the same or larger dimensions than the emission control unit 74, seen from the front. This advances the effect of preventing static electricity accumulated in the exterior member 72 to reach the emission control unit 74.
The exterior member 72 and the conductive sheet 73 are in contact with each other through contact portions 72s of the back of the through holes 72a of the exterior member 72, and the contact portions 73s of the front surface of the conductive sheet 73.
Connected to an end of the conductive sheet 73 is a ground unit 71 which grounds the conductive sheet 73.
Next, an operation of the emission device 70 is described with reference to
The conductive sheet 73 is placed to a position interposing between the exterior member 72 and the emission control unit 74. Thus, the electricity accumulated in the exterior member 72 is absorbed by the conductive sheet 73 grounded via the ground unit 71, while being transmitted to the emission control unit 74. This prevents the electricity from reaching the emission control unit 74. Thus, this is effective for preventing damage to the emission control unit 74 caused by electricity accumulated in the exterior member 72 reaching the emission control unit 74.
Further, the exterior member 72 is made of a material having electrostatic propensity (e.g., plastic). This increases the possibility of damaging the emission control unit 74 due to static electricity accumulated in the exterior member 72; however, damage to the emission control unit 74 is effectively prevented by the conductive sheet 73.
Furthermore, the exterior member 72 does not accumulate static electricity since it is in contact with the conductive sheet 73. This surely prevents damage to the emission control unit 74 caused by conduction of static electricity to the emission control unit 74, as well as prevents players from feeling electrostatic shocks even if the players touch the exterior member 72. Thus, electrostatic shocks which irritate players are prevented. Thus, this prevents possible inconvenience to both the gaming machine and players.
Although the conductive sheet 73 is a plate as an embodiment of the present invention, a conductive sheet 173 having oblique notches 173b formed on a plate 173c may be employed.
(Electrical Structure of Gaming Machine 1)
(Electrical Structure of Gaming Terminal 10)
The gaming board 50 is provided with a CPU (Central Processing Unit) 51, a ROM 55, a boot ROM 52, a card slot 53S corresponding to a memory card 53, and an IC socket 54S corresponding to a GAL (Generic Array Logic) 54. The CPU 51, the ROM 55, and the boot ROM 52 are connected to one another through an internal bus.
The memory card 53 stores therein a game program and a game system program. The game program contains a stop symbol determining program. The stop symbol determining program determines symbols (code number corresponding to the symbol) to be stopped in the arrangement areas 150. This stop symbol determining program contains sets of symbol weighting data respectively corresponding to various payout rates (e.g., 80%, 84%, 88%). Each set of the symbol weighting data indicates, for each of the display windows 151 to 155, a code number of each symbol and at least one random numerical value allotted to the code number. The numerical value is a value within a predetermined range of 0 to 256 for example.
The payout rate is determined based on payout rate setting data output from the GAL 54. Based on a set of the symbol weighting data corresponding to the payout rate determined, a symbol to be stopped is determined.
The memory card 53 stores therein various types of data for use in the game programs and the game system programs. For example, the memory card 53 stores a table listing combinations of a symbol to be displayed on the display windows 151 to 155 of
The card slot 53S is structured so as to allow the memory card 53 to be attached/detached to/from the card slot 53S. This card slot 53S is connected to the motherboard 40 through an IDE bus. Thus, the type and content of a game run by a gaming terminal 10 can be modified by detaching the memory card 53 from the card slot 53S, writing a different game program and a different game system program into the memory card 53, and inserting the memory card 53 back into the card slot 53S.
Each of the game programs includes a program related to the progress of the game and/or a program for causing a transition to a bonus game. Each of the game programs includes image data and audio data output during the game.
The GAL 54 has input and output ports. When the GAL 54 receives data via the input port, it outputs data corresponding to the input data from its output port. This data from the output port is the payout rate setting data described above.
IC socket 54S is structured so as to allow the GAL 54 to be attached/detached to/from the IC socket 54S. The IC socket 54S is connected to the motherboard 40, via a PCI bus. Thus, the payout rate setting data to be output from GAL 54 can be modified by: detaching the GAL 54 from the IC socket 54S, overwriting the program stored in the GAL 54, and attaching the GAL 54 back to the IC socket 54S.
The CPU 51, the ROM 55 and the boot ROM 52 connected through an internal bus are connected to the motherboard 40 through the PCI bus. The PCI bus communicates signals between the motherboard 40 and the gaming board 50 and supplies power from the motherboard 40 to the gaming board 50. The ROM 55 stores country identification information and an authentication program. The boot ROM 52 stores a preliminary authentication program and a program (boot code) for enabling the CPU 51 to run the preliminary authentication program.
The authentication program is a program (falsification check program) for authenticating the game program and the game system program. The authentication program is a program for confirming and verifying that the game program and the game system program are not falsified. In other words, the authentication program is described in accordance with a procedure for authenticating the game program and the game system program. The preliminary authentication program is a program for authenticating the authentication program. The preliminary authentication program is described in accordance with a procedure for verifying that the authentication program to be authenticated is not falsified. In short, the preliminary authentication program authenticates the authentication program.
The motherboard 40 is provided with a main CPU 41 (terminal controller 100), a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, and a communication interface 44.
The main CPU 41 serves as a terminal controller 100 and has a function of controlling the entire gaming terminal 10. In particular, the main CPU 41 controls the following operations: an operation of outputting a signal instructing variable-displaying of symbols to the graphic board 68, which is performed in response to pressing of the spin button 23 after betting of credit; an operation of determining symbols to be stopped after the variable-displaying of symbols; and an operation of stopping the symbols thus determined in the display window 151 to 155.
In other words, the main CPU 41 serves as an arrangement controller which arranges symbols to form a new symbol matrix through scrolling of symbols displayed on the lower image display panel 16. This main CPU 41 therefore determines symbols to be arranged in a symbol matrix by selecting symbols to be arranged from various kinds of symbols. Then, the main CPU 41 executes arrangement control to stop scrolling the symbols to present the symbols thus determined.
The ROM 42 stores a program such as BIOS (Basic Input/Output System) run by the main CPU 41, and permanently-used data. When the BIOS is run by the main CPU 41, each of peripheral devices is initialized and the game program and the game system program stored in the memory card 53 are read out through the gaming board 50. The RAM 43 stores data or a program used for the main CPU 41 to perform a process.
The communication interface 44 is provided to communicate with a host computer and the like equipped in the gaming facility, through the network (communication line). The communication interface 44 is also for communicating with the center controller 200 through a communication line. Further, a main body PCB (Printed Circuit Board) 60 and a door PCB 80 are connected to the motherboard 40, through USB (Universal Serial Bus). Further, the motherboard 40 is connected to a power unit 45. The power unit 45 supplies power to the motherboard 40 to boot the main CPU 41 thereof. Meanwhile, the power unit 45 supplies power to the gaming board 50 through the PCI bus to boot the CPU 51 thereof.
The main body PCB 60 and door PCB 80 are connected to various devices or units which generate signals to be input to the main CPU 41, and various devices or units whose operations are controlled by signals from the main CPU 41. Based on a signal input to the main CPU 41, the main CPU 41 runs the game program and the game system program stored in the RAM 43, to perform an arithmetic process. Then, the CPU 41 stores the result of the arithmetic process in the RAM 43, or transmits a control signal to the various devices and units to control them based on the result.
The main body PCB 60 is connected with a lamp 30, a hopper 66, a coin sensor 67, a graphic board 68, the speaker 29, a bill validator 22, a ticket printer 35, a card reader 36, a key switch 38S, and a data displayer 37.
The lamp 30 is turned on/off on the basis of a control signal from the main CPU 41.
The hopper 66 is mounted in the cabinet 11 and pays out a predetermined number of coins from a coin outlet 19 to the coin tray 18, based on a control signal from the main CPU 41. The coin sensor 67 is provided inside the coin outlet 19, and outputs a signal to be input to the main CPU 41 upon sensing that a predetermined number of coins have been delivered from the coin outlet 19.
The graphic board 68 controls image displaying of upper image display panel 33 and the lower image display panel 16, based on a control signal from the main CPU 41. Further, the graphic board 68 is provided with a VDP (Video Display Processor) for generating image data on the basis of a control signal from the main CPU 41, a video RAM for temporarily storing the image data generated by the VDP, or the like. Note that image data used at the time of generating the image data by the VDP is in a game program which is read out from the memory card 53 and stored in the RAM 43.
The bill validator 22 reads an image on the bill and takes only those recognized as to be genuine into the cabinet 11. When taking in a genuine bill, the bill validator 22 outputs an input signal indicating the value of the bill to the main CPU 41. The main CPU 41 stores into the RAM 43 a credit-value corresponding to the value of the bill indicated by the signal.
The ticket printer 35 prints a barcode onto a ticket to issue a ticket 39 having the barcode. The barcode contains encoded data such as credit-value stored in the RAM 43, date and time, identification number of the gaming terminal 10, or the like, based on a control signal from the main CPU 41.
The card reader 36 reads out data from the smart card and transmits the data to the main CPU 41. Further, the card reader 36 writes data into the smart card based on the control signal output from the main CPU 41. The key switch 38S is mounted to the keypad 38, and outputs a signal to the main CPU 41 in response to an operation of the keypad 38 by the player. The data displayer 37 displays, based on a control signal from the main CPU 41, the data read by the card reader 36 or the data input by the player through the key pad 38.
The door PCB 80 is connected to a control panel 20, a reverter 21S, a coin counter 21C, and a cold cathode tube 81. The control panel 20 is provided with: a spin switch 23S associated with the spin button 23; a change switch 24S associated with the change button 24; a cashout switch 25S associated with the cashout button 25; a 1-BET switch 26S associated with the 1-BET button 26; and a maximum BET switch 27S associated with the maximum BET button 27. Each of the switches 23S to 27S outputs a signal to the main CPU 41, when a player presses the associated button.
The coin counter 21C is provided within the coin insertion slot 21, and identifies whether the coin inserted into the coin insertion slot 12 by the player is genuine. A coin except the genuine coin is discharged from the coin outlet 19. In addition, the coin counter 21C outputs an input signal to the main CPU 41 upon detection of a genuine coin.
The reverter 21S is operated on the basis of the control signal output from the main CPU 41 and distributes a coin, which is recognized as a genuine coin by the coin counter 21C, to a not-shown cash box or hopper 66 mounted in the gaming terminal 10. In other words, when the hopper 66 is full of the coins, the genuine coin is distributed into the cash box by the reverter 21S. On the other hand, when the hopper 66 is not yet full with the coins, the genuine coin is distributed into the hopper 66. The cold cathode tube 81 functions as a backlight mounted to rear sides of the lower image display panel 16 and the upper image display panel 33. This cold cathode tube 81 turns on according to a control signal from the main CPU 41.
(Electrical Structure of Center Controller 200)
The gaming board 260 has the same structure as that of the gaming board 50. The mother board 240 has the same structure as that of the mother board 40. A communication unit 244 is for communicating with the terminal controllers 100 through a communication line.
The graphic board 268 has the same structure as that of the graphic board 68, except that the graphic board 268 controls displaying of the bonus payout indicator 300 (including emission control of the light emitting portions 320) based on a control signal from the main CPU 241.
A light emitting portion control circuit 404 controls the operation of the LEDs provided as the light emitting portions 403, and activates and inactivates the light emitting portions 403 based on the control signal output from the main CPU 241.

(Operation of Gaming Machine 1: Boot Process)
The following describes a boot process routine which takes place in the gaming machine 1. Upon powering on the gaming machine 1, a boot process routine shown in
First, turning on the power switch of (powering on) the power units 45 and 245 boots the motherboards 40 and 240, and the gaming boards 50 and 260. Booting the motherboards 40 and 240 and the gaming boards 50 and 260 starts separate processes in parallel. Specifically, the CPUs 51 and 261 read out preliminary authentication programs stored in the boot ROMs 52 and 262, respectively. Then, preliminary authentication is performed according to the read out programs so as to confirm and authenticate that no modification is made to authentication programs, before reading them in the motherboards 40 and 240, respectively (S1). Meanwhile, the main CPUs 41 and 241 of the motherboards 40 and 240 run BIOS stored in the ROMs 42 and 242 to load into the RAMs 43 and 243 compressed data built in the BIOS, respectively (S2). Then, the main CPUs 41 and 241 run a procedure of the BIOS according to the data loaded into the RAMs 43 and 243 so as to diagnose and initialize various peripheral devices (S3).
The main CPUs 41 and 241, which are respectively connected to the ROMs 55 and 265 of the gaming boards 50 and 260 via PCI buses, read out authentication programs stored in the ROMs 55 and 265 and stores them in the RAMs 43 and 243 (S4). During this step, the main CPUs 41 and 241 each derives a checksum through ADDSUM method (a standard check function) which is adopted in a standard BIOS, and store the authentication programs into RAMs 43 and 243 while confirming if the operation of storing is carried out without an error.
Next, the main CPUs 41 and 241 each checks what connects to the IDE bus. Then, the main CPUs 41 and 241 access, via the IDE buses, to the memory cards 53 and 263 inserted into the card slots 53S and 263S, and read out game programs and game system programs from the memory cards 53 and 263, respectively. In this case, the CPUs 41 and 241 each reads out four bytes of data constituting the game program and the game system program at one time. Next, according to the authentication programs stored in the RAMs 43 and 243, the CPUs 41 and 241 authenticate the game program and the game system program read out to confirm and prove that these programs are not modified (S5).
When the authentication properly ends, the main CPUs 41 and 241 write and store the authenticated game programs and game system programs in RAMs 43 and 243 (S6).
Next, the main CPUs 41 and 241 access, via the PCI buses, to the GALs 54 and 264 attached to the IC socket 54S • 264S, and read out payout rate setting data from the GALs 54 and 264, respectively. The payout rate setting data read out is then written and stored in the RAMs 43 and 243 (S7).
Next, the main CPUs 41 and 241 read out, via the PCI buses, country identification information stored in the ROMs 55 and 265 of the gaming boards 50 and 265, respectively. The country identification information read out is then stored in the RAMs 43 and 243 (S8).
After this, the main CPUs 41 and 241 each perform an initial process of
(Operation of Gaming Machine 1: Initial Process)
The following describes an initial process which takes place in the gaming machine 1. When the boot process of
First, the main CPU 41 of each of the gaming terminals 10 checks operations of work memories such as the RAM 43, various sensors, various driving mechanisms, and various decorative illuminations (A1). Then, the main CPU 41 determines if all the check results are normal (A2). If the main CPU 41 determines that the check results contains an error (A2: NO), the main CPU 41 outputs a signal notifying the error (hereinafter, error signal) to the center controller 200 (A3). Further, the main CPU 41 reports the error in the form of illuminating the lamp 30 or the like (A4), and then ends the routine.
On the other hand in A2, if the main CPU 41 determines that all the check results are normal (A2: YES), an initial setting signal is output to the center controller 200 (A5). Then, an initial setting signal is waited from the center controller 200 (A6, A7: NO).
The main CPU 241 of the center controller 200 receives signals from each of the terminals (B1). Then, the main CPU 241 determines whether a signal received is an error signal (B2). If the main CPU 241 determines that the signal is an error signal (B2: YES), the main CPU 241 outputs the error signal to a server of a not-shown host computer or the like (B9) to report the error (B10), and ends the routine.
On the other hand in B2, if the main CPU 241 determines that the signal is not an error signal (B2: NO), the main CPU 241 determines whether a predetermined time (check time) has elapsed from the time of powering on (B3). If the main CPU 241 determines that the check time has elapsed (B3: YES), B9 is executed. On the other hand, if the main CPU 241 determines that the check time has not yet elapsed (B3: NO), it is determined whether an initial setting signal is received from each of the gaming terminals 10 (B4). If the main CPU 241 determines that an initial setting signal from any one of the gaming terminals 10 is not received (B4: NO), the process returns to B1. On the other hand, if it is determined that initial setting signals from all the gaming terminals 10 are received (B4: YES), the main CPU 241 checks operations of work memories such as RAM 243, various sensors, various driving mechanisms, and various decorative illuminations (B5). Then, the main CPU 241 determines whether all the check results are normal (B6). If the main CPU 241 determines the check results contain an error (B6: NO), the main CPU 241 executes B9.
On the other hand in B6, if the main CPU 241 determines that all the check results are normal (B6: YES), the main CPU 241 outputs an initial setting signal to all the gaming terminals 10 (B7), and causes the shared display 102 to display a demo-screen (B8). Then, the main CPU 241 ends the routine.
In A7, the main CPU 41 of each of the gaming terminals 10 determines that an initial setting signal is received from the center controller 200 (A7: YES), and causes the terminal display 101 to display a demo-screen (A7). The main CPU 41 then ends the routine.

On the other hand, if a coin is bet (C1: YES), the credit value stored in the RAM 43 is reduced according to the number of coins bet (C2). When the number of coins bet surpasses the number of coins equivalent to the credit value stored in the RAM 43, C2 is repeated without the reduction of the credit value. When the number of coins bet exceeds the maximum number of coins bettable one game (50 pieces in this embodiment), the process goes to a later-described step C3 without the reduction of the credit value.
Then, it is determined whether a spin button 23 is pressed (C3). If the spin button 23 is not pressed (C3: NO), the process returns to C1. Here, if the spin button 23 is not pressed (for example, the spin button 23 is not pressed but a command to end the game is input), the reduction of the credit value in C2 is canceled.
On the other hand, if the spin button 23 is pressed (C3: YES), a jackpot transmission process is executed (C4). In other words, a jackpot signal indicating a part of the game value bet is transmitted to the center controller 200.
Next executed is a symbol determining process (C5). That is, the stop symbol determining program stored in the RAM 43 is run to determine symbols to be arranged in the matrix. Through this, a symbol combination to be formed along the payline L is determined.
Then, the scrolling process is executed to scroll symbols on the terminal display 101 (C6). The scrolling process is a process in which the symbols determined in C5 are stopped (rearranged) in the matrix after scrolling of symbols in a direction indicated by an arrow symbol.
Next, it is determined whether symbols rearranged in the matrix form a winning combination (C7). If the symbols 180 form a winning combination (C7: YES), a payout process is executed (C8). More specifically, when a winning combination is formed, the number of coins according to the combination is calculated. On the other hand in C7, if it is determined that no winning combination is formed (C7: NO), C11 is executed.
After the execution of the payout process in C8, the main CPU 41 determines whether a bonus game is running and whether a predetermined winning is met (C9). If a bonus game start signal is received from the center controller 200, the main CPU 41 determines that the bonus game is running. If it is determined that the bonus game is running and a predetermined winning is met (C9: YES), a winning signal is output to the center controller 200 (C10) and the process of C11 is executed. On the other hand, if it is determined that the bonus game is not running or a predetermined winning is not met (C9: NO), the process of C11 is executed.
Next, the main CPU 41 determines whether a bonus award signal is received from the center controller 200 (C11). If the main CPU 41 determines that a bonus award signal is received (C11: YES), a payout is awarded according to the bonus award signal (C12). The process then returns to C1. On the other hand in C11, if the main CPU 41 determines that no bonus award signal is received (C11: NO), the process returns to C1.

On the other hand in D1, if the main CPU 241 determines no jackpot signal is received (D1: NO), the main CPU 241 determines if the jackpot value equals or surpasses a predetermined value (D3). If it is determined that the jackpot value equals or surpasses a predetermined value (D3: YES), a bonus game start signal is output to each gaming terminal 10 (D4). Then, the process of D1 is executed.
If it is determined that the jackpot value does not equal or surpass a predetermined value (D3: NO), the main CPU 241 determines whether a winning signal is received from the terminal controller 100 (D5). If the main CPU 241 determines that a winning signal is not received (D5: NO), the process returns to D1. On the other hand, if it is determined that a winning signal is received (D5: YES), all of the light emitting portions 320 provided for the illuminating boards 310 in the illuminating device 300 (bonus payout indicator 300) are caused to emit light in the same color (D6). Then, the main CPU 241 determines a random number based on the path activation state table (D7). Then, the main CPU 241 updates the path activation state table based on the random number so determined (D8). The main CPU 241 then activates the light emitting portions 403 toward the bonus payout indicator 300, in numbers randomly determined as above (D9).
Then, it is determined whether a path 401 exists in which the light emitting portions 403 have been activated up to the bonus payout indicator 300, so as to determine whether conditions are met for awarding a bonus payout (D10). If it is determined that conditions for awarding a bonus payout are not met (D10: NO), the process returns to D1. On the other hand, if it is determined that conditions for awarding a bonus payout are met (D10: YES), the main CPU 241 causes the light emitting portions 320, provided for the illuminating boards 310 in the illuminating device 300 (bonus payout indicator 300), to emit light in different colors (D11). Then, a bonus award process is executed to award a bonus payout, and a bonus award signal is output to the gaming terminal 10 subject to the bonus payout (D12). Then, the amount of jackpot value consumed is reduced from the RAM 243 (D13), and a bonus game end signal is output to each gaming terminal 10 (D14). The process then returns to D1.
