Description

-1 GAMING MACHINE CABINET [0001] The present invention relates to a gaming machine cabinet for gaming machines, which are used in casinos, particularly relates to a gaming machine cabinet having a modular structure with an ergonomic structure suitable for players of the gaming machines. BACKGROUND [0002] In a current gaming machine cabinet or housing, there are two types of gaming machines from the viewpoint of the gaming machine cabinet structures. One of them is a gaming machine configuration, which is referred to as "an upright" or "an arcade" configuration, and the other gaming machine configuration is a gaming machine, which is referred to as "a slant top" configuration. [0003] The upright gaming machine is generally tall and narrow structure as disclosed by The United States Patent Application Publication No. 2004/0224776 to Nagano, which teaches the "upright" or "arcade" configurations of the gaming machine.

-2 [0004] The other gaming machine configuration is referred to as a "slant top" as disclosed in the U.S. Pat. No. 6,201,532B1 to Tode et al and The United States Patent Application Publication No. 2005/0026702 to Cole. Typically, theses gaming machines include a top display portion, and it has a sloping or slanted section where input buttons are located. [0005] In both types of gaming machines, there are commonly two drawbacks. One of them is that that once the gaming machine is manufactured, it is difficult change the configuration of the gamingmachine. Forexample, in case when adding one more display to the gaming machine, it was necessary to remove the side panels and the front panel of the gaming machine to add one more display to the gaming machine and to replace at lease the side panels and the front panel. The other drawback is the size of the gaming machine. Particularly, in the case of slant top configuration, the depth of the gaming machine is relatively longer than that of the upright structure gaming machine. Thus, the number of gaming machines placed on the casino floor has been limited. [0006] In order to solve the problems, US patent 6,820875 to Hedrick et al discloses a modular cabinets and replaceable laminate panel for a gaming device and a monitor cover removably connected to -3 the display cabinet. However, it is still difficult to add an additional display device to change the configuration of the gaming machine. [0007] Further, in recent years, flat panel display devices such as LCD (Liquid Crystal Device) panels and PDP (Plasma Display Panel) are available in a marketplace with relatively less expensive. As a result of this trend, the depth of the gaming machine has been shortened relative to the prior gaming machine based using CRT (Cathode Ray Tube). [0008] However, prior art has not taken full advantages of these devices into the gaming machines. [0009] An object of the present invention is to provide a gaming having a modular structure capable of being flexibly configured. The other object of the present invention is to provide a gaming machine having an ergonomic structure suitable for players of the gaming machines.

[0011] Preferably the third cabinet includes a front side surface, at least a part of which recesses toward a rear side of the third cabinet, a recessed amount of the front side surface increasing toward a lower section of the front side surface. [0012] Preferably the second display includes a mechanical reel -5 unit. [0013] In an alternative aspect of the present invention is to provide a gaming machine including, a first cabinet including a first display for displaying a first game, a second cabinet including a second display for displaying a second game, and a third cabinet including an input device for playing the game, wherein an area of a top surface of the third cabinet is wider than an area of a bottom surface of the second cabinet or a bottom surface of the first cabinet. [0014] In the gaming machine of described above, the depth of the top surface of the third cabinet is longer than a depth of the bottom surface of the first cabinet or the second cabinet at least by three inches. [0015] According to an embodiment of the present invention described above, since the gaming machine is configured by a modular structure, that is, the gaming machine is configured by the first cabinet including a first display, the second cabinet including the second display and the third cabinet including the input devices, each of which has an independent modular structure, -6 it becomes possible to swiftly configure the gaming machine requiredfrommarket needs. Forexample, inthe case whenacasino operator requires a gaming machine having first cabinet and the third cabinet without having the second cabinet, it is possible to provide the gaming machine having the first cabinet and the third cabinet. Further, since the top surface of the third cabinet is larger than the bottom surface of the first cabinet, in the case when the first cabinet is placed on the third cabinet, the top surface of the third cabinet may be used as a player table for placing small personal items thereon. [0016] Another aspect of the present invention, there is provided a gaming machine wherein a bill acceptor for inputting a bill for betting the first game or the second game is installed below the top surface of the third cabinet. [0017] In the gaming machine described above, a printer for printing data pertaining to bet information of the first game or the second game is installed below the top surface of the third cabinet. [0018] According to the gaming machine described above, since the bill acceptor and the printer, which have relatively long depth in size, are installed below the top surface of the third cabinet, -7 the depth of the third cabinet is to be longer than the bottom surface of the first cabinet or the second cabinet in general. Thus, in the case when the first cabinet or the second cabinet isplacedonthe thirdcabinet, the topsurface ofthe thirdcabinet may be used as a player table onto which small personal items can be placed. [0019] In the gaming machine described above, the top surface of the third cabinet extended from the front surface of either the first cabinet or the second cabinet has a collar attached around the edge of a player side or a concave portion being lower than the top surface of the third cabinet in height. [0020] According to the embodiment described above, since the top surface of the third cabinet has a collar attached around the edge of the player side or a concave portion of the top surface of the third cabinet, small items, for example, cups, tokens and coins can be placed on the top surface of the third cabinet, which may be used as a player table. [0021] In the gaming machine described above, the third cabinet includes a front side surface recessed toward a rear side relative to the player, the recessed amount of the front side surface -8 increasing toward a lower section of the front side surface. [0022] According to the gaming machine described above, the free space for player's feet can be secured so that player can play games under a relax state. [0023] The gaming machine further includes a fourth cabinet including a controller for controlling an operation of the gaming machine and the first game and the second game.

[0025] In the gaming machine, the light device is placed so as to be visible at least from a front side of the gaming machine. [0026] According to an embodiment described above, since the cabinet including the controller for controlling an operation of the gaming machine may be separately provided, the flexibility -9 of the gaming machine configuration can be further increased. Forexample, in the case when two types of controllers areprovided in two independent cabinets, game manufactures can provide wide range of the gaming machines by combining the controllers with the first cabinet, secondcabinet andthe thirdcabinet. Further, since the light device is mounted between the cabinets, that is, the light device is independent from the cabinet, the light device can be relatively easily and swiftly attached or detached based on the casino operator requirements, which can increase the flexibility of the gaming machine configuration. [0027] In the gaming machine described above, data communication between the first cabinet and the controller, the second cabinet and the controller and the third cabinet and the controller is performed through a serial bus or a wireless communication device. [0028] According to an embodiment described above, since the data communication between the controller and each cabinet is performedvia a serial bus, a smaller connector and less expensive communication lines can be realized comparing with parallel transmission line, which is also help to minimize the size of the cabinet. In the case when the data communication for each cabinet is performed via a wireless communication device, since -10 the communication line between cabinets can be omitted, the cabinet arrangement can be increased. [0029] In another aspect of the present invention there is provided a gaming machine including, a first cabinet including a display for displaying a first game, a second cabinet including a second display for displaying a second game, and a third cabinet including a plurality of input buttons for playing the first game and the second game, an input device having an input slot and an output device having an output slot, wherein at least either the input slot or the output slot is positioned not lower than a top surface of the an input buttons located in front of the input slot in height from the bottom surface of the third cabinet.

DETAILED DESCRIPTION OF THE INVENTION [0046] Fig. 1 illustrates a gaming machine la having a modular -14 structure for a video gaming machine of an embodiment of the present invention. The gaming machine la is configured by a first cabinet 11 including a display 3a, a second cabinet 12a including a second display 2b, a third cabinet 14a including input devices for playing the game and a fourth cabinet 13a including a controller for controlling each section of the gaming machine la. The gaming machine la is generally set up on a game stand 15 depending on a situation where the gaming machine is setup. [0047] As shown in Fig. 1, a part of the top surface of the third cabinet 14a facingtotheplayer is designedtobe slanteddownward so that the player can easily operate input buttons and input devices for the games displayed on the first display 3a and/or the second display 2b. With respect to the input buttons, there are provided BET switches 4, selection switches 5, aMAXBET switch 6 a PAYOUT switch 7, start buttons 21 and 22a. With respect to the input devices, there are provided a coin slot 8 and a bill acceptor 9. The BET switches 4 include five switches from 1BET to 5BET. The selection switches 5 include five switches from 1 (one) select to 5 (five) selects of bet lines. A coin payout mouth 10 is provided in the lower part of the third cabinet 14a. Further, there is provided an output device, for example, a printer 20on a slanted surface 14s of the third cabinet for -15 outputting printed material pertaining to the game of the gaming machine la. [0048] The instruction for performing a primary game or a secondary game is normally displayed on the first displays 3a. Cards used by a card game, roulette used in a roulette game and reels used inareel game are displayedonthe seconddisplays 2a, forexample. [0049] The BET switches 4 are switches for inputting a bet on the game. The player can input a bet from 1BET to 5BET using the BET switches 4 one time for a game. A selection switch 5 is a switch for, for example, selecting a line on the reels and the card, which the player wants to set on the games. [0050] The MAXBET switch 6 is a switch for inputting the maximum bet that a player can spend against one time of a game. A PAYOUT switch 7 is a switch for rewarding the amount of money to a player, which has been credited onto the gaming machine. The start buttons 21 and 22a are buttons for starting game. The starting buttons 21 and 22a may be arranged on the slanted surface 14s of the third cabinet and sidewall of the third cabinet so that the player can select the startingbutton for his or her preference in this embodiment. A coin slot 8 is a hole for a player to insert -16 the coin to the gaming machine. A bill acceptor 9 is a input and output device to be used in order to feed a bill or a cash card into the gaming machine, or in order to repay the amount of money, which has been credited. The coin tray mouth 10 is a tray in to reward the amount of money to a player, which has been credited in the gaming machine. [0051] As shown in Figs. 1 and 3, the gaming machine 1 is configured by independent cabinets, such as the first cabinet 11 including the first display 3a, the second cabinet 12a including the second display 2a, the third cabinet 14a including the input device and the output device for playing the game and the fourth cabinet 13a including the controller for controlling games displayed on the first and the second displays 3a and 2a, the input buttons and input devices as described above, speakers 16 and light devices 17, which are synchronized with the game played on the gaming machine la. According to one of embodiments of the present invention, the controller for controlling an operation of each functionof the gaming machine maybe included in the third cabinet together with the input and out devices so that fourth cabinet may be omitted. However, in this case, speakers 16 provided in the fourth cabinet needs to be installed into other cabinets for example, the first cabinet, the second cabinet and/or third -17 cabinet. [0052] As shown in Fig. 1, since the gaming machine is structured by the first cabinet, the second cabinet, the third cabinet and the fourth cabinet, it is easy to change the configuration of the gaming machine. For example, in the case where the gaming machine including the first display and the second display has been installed on the casino floor and later new games, which needonly one display, havebeen installed into the gaminemachine, it is easy to change the configuration of the gaming machine by removing the first cabinet from the gaming machine without changing the whole gaming machine by utilizing the advantages of the modular structure of the gaming machine. [0053] The other advantage of the modular structure of the gaming machine is that gaming machine manufactures can respond a plurality of requirements for the gaming machine configurations by providing necessary types of modular cabinets without providing necessary types of whole gaming machines. Thus the gaming machine manufactures can reduce the inventory cost and quickly respond the markets needs by configuring the gaming machines by using necessary modular cabinets.

-18 [0054] By taking these advantages of the modular structure of an embodiment of the present invention, it becomes possible to quickly respond the different kinds of needs of gaming machine configurations using predetermined modular cabinets. For example, in the case where one casino operator requires a gaming machine having only one display and the other operators require a gaming machine having two displays with light devices between the first cabinet and the second cabinet and the between the second cabinet and the fourth cabinet, according to an embodiment of the present invention, it becomes possible to supply gaming machines to both casino operators by selecting necessary number of displays to configure the requested gaming machine having necessary light device requirements to respective casino operators without having two types of whole gaming machines. However, in the case of the gaming machine structure of the prior art described above, in order to satisfy various kinds of customer requirements, it is necessary to provide various types of gaming machines for respective casino operators in advance. Inpractice, when there is a plurality of potential casino operators for the gaming machines, in general, each casino operator has different kinds of configurations of the gaming machines. Thus, this modular cabinet configuration is effective to respond those needs in a timely manner.

-19 [0055] Next, the depth of the gaming machine and a player table provided on the top surface of the third cabinet will be described. In the case where there are provided two types of third cabinets 14a and 14c having different depth (the length from the front surface to the rear surface of the third cabinets 14a and 14c) depending on the location where the bill acceptor 9 is installed inside the third cabinets 14a and 14c as shown in Figs. 6 and 7, two types of gaming machines can be provided by preparing two types of third cabinets 14a and 14c while commonly using the first cabinet 11, the second cabinet 12a and the forth cabinet 13a for both gaming machines illustrated in Figs. 6 and 7. Thus by utilizing the modular cabinet structure, since the gamingmachine manufactures can only preparing cabinets having different functions and or dimension, it becomes possible to manufacture the gaming machines with less expensive operation cost comparing with the manufacturing cost of the gaming machines based on the prior art described above. [0056] As illustrated in Fig. 6, the bill acceptor 9 and the printer 20 (referring to Fig. 1) have a relatively long depth among the parts used in the gaming machine. In the gaming machine illustrated in Fig. 6, the bill acceptor 9 is horizontally -20 installed below the top surface of the third cabinet 14a. On the other hand, as illustrated in Fig. 7, the bill acceptor 9 is obliquely installed below the top surface of the third cabinet 14c so that the depth of the third cabinet 14c can be structured shorter than that of the third cabinet 14a as illustrated in Fig. 6. Based on these arrangements of the location of the bill acceptor 9 inside the fourth cabinets 14a and 14c, two types of third cabinets 14a and 14c having different depths can be provided, for example. [0057] In the case of the third cabinet 14a into which the bill acceptor 9 is horizontally installed as illustrated in Fig. 6 the player table 19a has a relatively wider area comparing with the area of the player table 19c of the third cabinet 14c illustrated in Fig. 7 when the same fourth cabinet 13a is placed on the top of the third cabinet. [0058] On the otherhand, since the total depth of the gaming machine using the third cabinet 14c illustrated in Fig. 7 can be shorter than that of the gaming machine using the third cabinet 14a illustrated in Fig. 6, more gaming machines using the third cabinet 14c can be placed on the same casino floor space than the gaming machine using the third cabinet 14a illustrated in -21 Fig. 6. [0059] Thus, it is possible to promptly respond wide range of requirements from casino operators by providing the different types of third cabinets having different depth using different kinds of installation position of the bill acceptor 9 in the third cabinet. Needless to say, as described above, the printer 20 installed inside the third cabinet is also one of the critical elements when designing the third cabinet. In this embodiment, the depth of the gaming machine has been described. However, it is not limitedtothe depthofthe gamingmachine. For, example, it is possible to prepare different types of input key layout, color of the modular cabinets of the gamingmachine and different types of functionality of the gaming machines. [0060] Fig. 2 illustrates a gaming machine having a modular structure for mechanical reels (stepper) of an embodiment of the present invention. As shown in Fig. 2, the second cabinet 12b includes a mechanical reels (stepper) 2b instead of the second display 2a in Fig. 1. In this embodiment, five mechanical reels are installed into the second cabinet 12b. In this embodiment, the fourth cabinet 13b including a controller having functions for controlling not only mechanical reels but also for controlling -22 games displayed on the first displays 3a, the input devices as described above and lamps and speakers associated with the game. Also, it is possible to provide a controller for controlling, the first display 3a, the second display 2a, the mechanical reels 2b and the input devices so that one type of controller can be utilized for different kinds of gaming machines. Further, the same as described above, it is also possible that the controller may be included in the third cabinet together with the input devices so that fourth cabinet may be omitted. [0061] Fig. 4 illustrates a modular structure of the gaming machine having mechanical reels (stepper) of an embodiment of the present invention. As illustrated in Figs. 3 and 4, the areas of the top surfaces (horizontal portion) of the third cabinets 14a and 14b are designed to be wider than the bottom surface of the fourth cabinet 13b, the second cabinets 12a and 12b and the first cabinet lso that a part of the top surface can be used as a player table or a player shelf, which will be described later. [0062] Fig. 5 illustrates the interchangeability between the video gaming machine la illustrated in Figs. 1 and 3 and the gaming machine lbhavingmechanical reels (stepper) illustrated in Figs. 2 and 4 of embodiments of the present invention. In the case -23 where the second cabinets 12a and 12b, the third cabinets 14a and 14b and the fourth cabinets 13a and 13b are designed to interchangeable even though the mechanical dimensions and functions are different each other, total eight type of combination will be available. Thus various kinds of requirements from market needs can be quickly responded by combining the necessary cabinets based on the requirements. [0063] Next, the player table will be described. In Fig. 1, input buttons, such as the BET switches 4, selection switches 5,the MAXBET switch 6 and the PAYOUT switch 7 are provided on the slant surface 14s of the third cabinet. Further, a player table or a player shelf 19a onto which a player can place small items, such as a cup for drinks, coins and tokens is provided in front of the cabinet 2 and/or the fourth cabinet 13a in this embodiment. [0064] Fig. 8 illustrates one of example of a player table or a player shelf 19a having a concave structure of the top surface of the third cabinet 14a extending toward the player side of the gaming machine of one embodiment of the present invention. The concave structure is designed to have a bottom surface, which is lower than the top surface of the third cabinet 14a in height.

-24 [0065] Fig. 9 illustrates the other example of a player table or a player shelf 19b having a collar 19c attached around the edge the top surface of the third cabinet 14d of an embodiment of the present invention. According to these structures described above, small items, whichplayer canput thereon, canbe prevented from sliding down from the player table or the player shelf. [0066] Further, according to an embodiment of the present invention, the depth of the top surface of the third cabinet is preferably designed to be longer than the depth of the bottom surface of the first cabinet 11, the second cabinet 12aandthe fourth cabinet 13a at least by 3 inches so that a mug cup and/or other personal items of the player can be placed thereon, which is convenient for the players of the gaming machine. [0067] The area on the top surface of the third cabinet 14a, which is utilized for the player table 19a, canbe securedby installing the bill acceptor 9 and the printer 20, which have relatively long depth among the parts used in the gaming machine 1, under the top surface of the third cabinet 14a or the player table 19a. In this embodiment, the bill acceptor 9 and the printer 20 are used as the input device and the output device respectively. However, the input device and the output device are not limited -25 to the bill acceptor 9 and the printer 20. For example, a card reader, which is capable of magnetically or optically reading data from a card type medium such as a magnetic card or an optical card including a cash card, and a card reader/writer, which is capable of reading/writing data from/onto a card type medium, such as a contact smart card and a non-contact smart card being a smart card, a debit card and a point card for the game machine may also be used as an input device and or an output device. [0068] Further as illustrated in Figs. 1- 7, the third cabinets 14a, 14b and 14c including the input devices includes a front side surface recessed toward a rear side relative to the player, a recessed amount of the front side surface increasing toward a lower section of the front side surface. Accordingly, the player of the gaming machines described above can freely move their feet when sitting down on the chair provided in front of the gaming machines. [0069] Next, light effects and sound effects in the gaming machine associated with the modular structure will be described hereinafter. In general, the light effects and the sound effects of the gaming machine are important factors to attract players to casino floor. The light device 17 is placed between the first -26 cabinet 11 and the second cabinet 12a and between the second cabinet 12a and the fourth cabinet 13a including the controller. Further, the light device 18 is mounted on the upper-front portion of the game stand 15 in this embodiment. The light device 18 attached in the game stand 15 may be mounted between the third cabinet 14a and the game stand 15. The light devices 17 and 18 are structured as following. A plurality of light elements is mounted on the bracket which is designed to fit the space formed between the modular cabinets when the modular cabinet is placed on the other modular cabinet. Since the bracket of the light device fit the space formed between the modular cabinets, it is possible to attach or detach the light devices onto or from the gaming machine having modular structure illustrated in Fig. 1, These light devices 17and 18 are electrically connected to the controller in the third cabinet 13a so that the lights emitted from the light devices 17 and 18 can be synchronized with the progress of the games. For example, when the big win is established in the game, the light devices 17 and 18 turn of and off (blinking) and game sound comes out from the speakers 16 provided in the fourth cabinet in this embodiment. [0070] The light devices 17 and 18 are designed to fit the spaces between respective cabinets so that it becomes easy to attach -27 those light devices 17 and 18 according to the configuration requirement from casino operators of the gaming machines even after having set the gaming machines on the casino floorsFurther, in the case when the gaming machine, which is configured by the second display 12a, the third cabinet 14a, the fourth cabinet 13a and the fifth cabinet 15, is provided, the light device 17 may be placed, between the second cabinet 12a and the fourth cabinet 13a and between third cabinet 14a and the game stand 15 even after having set up these gaming machine on the casino floor. [0071] Since the respective cabinets are designed to have the same space formed by respective cabinets when those cabinets are configured into a vertical direction, one standard size of light device can be placed and attached for each space between the cabinets. Since one type of light device in terms of the size, which can be placed and attached onto the gaming machine, the manufacturing cost of these light devices can be lowered. The light devices are formed, in general, by LED (Light EmittedDiode) devices having various kinds of colors associated with the situation of the game story. Needle to say, the light devices having different color arrangement can further widen the selections of the gaming machines.

-28 [0072] Fig. 12 illustrates a circuit diagram showing electrical connection between cabinets and light devices placed between the cabinets configuring a gaming machine. In this embodiment, the light devices 17 are placed between the first cabinet 11 and the second cabinet 12a, and between the second cabinet 12a and the fourth cabinet 13a. Further, the light device 18 is mounted in the game stand 15. Respective cabinets and light devices have a serial data interface, such as USB (Universal Serial Bus) and through which the controller inside the fourth cabinet 13a controls the operations of the game functions performed by each cabinet and light device. Since, control data communicated between respective cabinets and light devices is transmitted via serial data line, the diameter of the data line and the size of the connecters on each cabinet can be small, and the size of the connector of each cabinet and the light device can also be minimized. [0073] Next, the arrangement of the input buttons 21 located in front of the bill acceptor 9 will be described from the view point of ergonomic design of gaming machine of the embodiment described above. This arrangement may also be applicable to the arrangement of the MAXBET switch 6 for inputting the maximum bet that a player can spend against one time of a game and the PAYOUT switch 7, -29 which are located in front of the printer 20 provided on the slanted surface 14s of the third cabinet 14a. [0074] Fig. 10 illustrates the relationship between the input slot 9B of the bill acceptor 9 and the input buttons 21 located in front of the bill acceptor 9 viewed from in front of the gaming machine la and the starting button 22a positioned on the side surface of the third cabinet 14a. Fig. 11 illustrates relationship between the slot 9B of the bill acceptor 9 and the input buttons 21 located in front of the bill acceptor 9 and the starting button 22a positioned on the side surface of the third cabinet 14a viewed from the side of the gaming machine 1. [0075] In this embodiment, asillustratedinFig. 10, thetop surface of the input buttons 21 is positioned not higher than the height of the input slot 9B of the bill acceptor 9. According to this embodiment, the bill can be smoothly inputted to the input slot 9B of the bill acceptor 9. It is preferable that the distance Dl between the top surface of the input button 21 and the input slot 9B of the bill acceptor 9 is set from 1/4 inches to 1 inch (6mm - 25.4mm) . In case when the top surface of the input switch 21 is higher than the input slot 9B, the input button 21 will interfere the bill to be inserted to the input slot 9B. In the -30 case when the input button 21 is away from the input slot 9B, the operation flow from the insertion operation bill to start game cannot be smoothly performed. [0061] [0076] In the case where the bill acceptor 9 is obliquely installed in the third cabinet as shown in Fig. 7, since bills or cards can be obliquely inputted to the input slot 9B, the distance (Dl in Figs 10 and 11) between the top surface of the input button 21 and the input slot 9B of the bill acceptor may be set from 0 to 1 inch (0mm - 25.4mm). [0077] Further, a start button 22a for starting a game may be provided on the sidewall of the third cabinet as shown in Figs. 10 and 11. In general, the player tends to put his or her hand on the corner formed by the slant surface 14s and the sidewall of the third cabinet 14a. Further, before staring the game, the player normally input bills or a game card to the slot of the input deviceby theirrighthand, then startingthe gamebypushing the start button. Thus the position of the staring button 22A is one of the key factors for determining the smooth operation of the gaming machine. Thus the starting button 22A for starting a game is positioned close to the input slot 9B of the input device 9.

-31 [0078] In this embodiment, the start key may be set in front of the input slot 9B of the bill acceptor 9 or the sidewall of the third cabinet 14c. In the case where the start button 22A is positioned on the sidewall of the third cabinetl4c, the center of the start button 22A is positioned in a distance (D2 in Figs. 10 and 11) from 3/4 inches to 7 inches (20mm to 180mm) lower than the slot of the input device 9. As described above, in the case where the start button 22A is away from the input slot 9B of the bill acceptor 9, the operation flow from the insertion operation bill to start game cannot be smoothly performed. [0079] Next, the total operations of the gaming machine will be described by using the block diagram of the gaming machine la illustrated in Fig. 13. [0080] Fig. 13 illustrates a block diagram of an embodiment of the present invention. As shown in FIG. 13, the main control board (controller) 400 includes a main CPU 401, a first I/O port 404, a second I/O port 407, a third I/O port 406, a fourth I/O port 405, a ROM 402, a RAM 403, a video controller 410, a lighting controller 411, a sound controller 412, a payout controller 413, a card reader/writer 408a and a display controller 409.

-32 [0081] The first I/O port 404a is used in communication between the main control board 400 and the sub-control board (not shown). The second I/O port 407 is used in communication between the main control board 400 and the coin slot 8, the coin payout mouth 10 and input buttons 4, 5, 6, 7, 21 and 22a. The third I/O port 406 is used in communication between the main control board 400 and a server (not shown) through the communications network. The fourth I/O port 405 is used in communication between the main control board 400 andthe bill acceptor 9, the printer 20, displays 2a and 3a, the light devices 17 and 18 and speakers 16. [0082] The ROM 402 stores various programs, e.g., a communications program and various gaming programs. The main CPU 401 invokes the programs for games performed on the gaming machine la. [0083] The RAM 403 temporally stores results computed by the CPU 401. The videocontroller410 controls the display on the displays 2a and 3a under control of the CPU 401. The lighting controller 411 switches the lamps 17 and 18 on and off under control of the CPU 401. [0084] The sound controller 412 controls the speakers 16 to -33 reproduce voice announcements, sound effects, and the like under control of the CPU 401. [0085] The payout controller 413 controls the coin payout mouth 10 to supply a proper amount of coins under control of the CPU 401. [0086] The card reader/writer 408 reads and writes data from and onto the card inserted in the in the printer 20 under control of the CPU 401. Also, the card reader/writer 408 controls the count of number of bills inserted from the bill acceptor 9 under the control of the CPU 401. [0087] The CPU 401 is connected to the input buttons 4, 5, 6, 7, 21 and the start button 22a, the MAXBET switch 6 and the PAYOUT switch 7, and transmits operation signals through the second I/O port 407. [0088] Moreover, the CPU 401 is also connected to a coin counter (not shown in figures) that counts the amount of cash inserted into the coin slot 8. [0089] The block diagram illustrated in Fig. 13 describes the -34 functions of each section of the gaming machine la illustrated in Fig. 1. In the case of the gaming machine lb having mechanical reels 2b, the control programs for the mechanical reels 2b is stored in the ROM 402 and the mechanical reels 2b connected to the control board 400 instead of the display 2a will be controlled by the CPU 401. As described previously, the control programs for the mechanical reels 2b will be able to be installed together with the control programs for the display 2a into the ROM 402 so that one controller can be used not only gaming machine la but also the gaming machine lb. [0090] The present invention is not limitedto the above embodiments andvarious changes andmodification maybe made without departing fromthe scope of the invention. For example, in this embodiment, the controller is installed inside the forth cabinet. However, the controller may be installed in the third cabinet, or may be installed in either the first cabinet or the second cabinet. Further, in this embodiment, the data is transmitted via a serial transmission line, such as USB. However, the data transmission may be performed via a cordless communication devices installed each cabinet so that the transmission line can be omitted.
