Description

  The present invention relates to a centralized monitoring and management system for gaming halls, and more specifically, to all gaming machines and surveillance equipment that are managed and managed in all gaming halls (hereinafter collectively referred to as equipment and devices). Each game hall is generated by analyzing and analyzing the operation data of the gaming machine and the history information of each device identified by the wireless IC tag incorporated in each gaming machine and gaming equipment. Encrypted information (hereinafter referred to as island information) is managed by encryption and network connection technology, which is integrated in the administrator server / client via a hierarchical network, and island information of all these series halls. A virtual cipher hall (hereinafter simply referred to as a virtual hall), which is a gaming hall on a computer configured for management purposes, with monitoring and management information necessary for device management. Virtual management information generation technology to be generated as “Fa Hall” and virtual management information is provided to the management of the game hall, and this information is provided to the supervisory body of the gaming machine other than the management of the gaming hall, It is shared with game industry personnel such as machine manufacturers to improve management and fraud monitoring of the game hall, and data sharing technology that can quickly deal with various problems related to the game hall. This is related to a centralized monitoring and management system.

In general, in a game hall where a large number of gaming machines and game-related equipment are installed, several machines to 20 machines and games-related equipment can be easily maintained and managed, and players can pass smoothly. Divided into groups (islands) of about one table.
FIG. 12 is a schematic diagram showing an arrangement example of devices in a conventional game hall.
In FIG. 12, 1 is a game hall, 2 is a game machine such as a pachinko (bullet ball game machine), a slot machine (rotor-type game machine), 3 is a game media rental machine, and the number of game media acquired by the player Game-related equipment such as counting machines, prepaid card vending machines, store visitors, and surveillance cameras. A plurality of gaming machines 2 and game related equipment 3 are arranged in a group to form an island 4. In general, in the island 4, the gaming machines 1 are arranged in two rows with the backs facing each other, and a gaming medium rental machine (game-related equipment 3) is arranged between the gaming machines 2.
A surveillance camera (game-related equipment 3) is appropriately arranged on the ceiling in order to monitor a suspicious behavior person. 9 is a chair on which a player sits, and 10 is a guide counter.
Between the rows of gaming machines 2 arranged in two rows, a step-down transformer 8 that steps down the commercial power supply to 24V is appropriately disposed. This is because many game machines have a power supply voltage of 24V, and this is not necessary if the power supply of the gaming machine can use the commercial power supply as it is.

In addition, between the rows of gaming machines 2, island computers 5 that accumulate operating data of the gaming machines 2 are arranged. The operation data of the gaming machines 2 on each island 4 accumulated by the island computer 5 is further accumulated in a hall computer (not shown) installed in a management room or the like in the gaming hall 1 to manage the management of the gaming hall. Monitored and managed by an administrator.
In the conventional gaming hall, the operating data of the gaming machine 2 in the gaming hall 1 is accumulated and managed in the hall computer, but the operating data of the gaming related equipment 3 is separate from the operating data of the gaming machine 2. Are collected and individually monitored and managed.
As described above, the main reason why the operation data of the gaming machine 2 and the game related devices 3 cannot be centrally managed via the network is that the data and transfer method of these devices are different from each other following the conventional method. Therefore, each device constructs an individual data communication line, and each data is concentrated and accumulated in the hall computer, and data of all gaming machines and game-related devices are distributed and accumulated by a flexible network. The system could not be constructed.

In recent years, a centralized system has been proposed in which these data and data of devices having different transfer methods are integrated and managed centrally.
For example, Patent Document 1 discloses a technique for collectively managing data of gaming machines, safes, prepaid card vending machines, etc. in gaming halls using a management computer.
FIG. 13 is a configuration diagram of the game hall management system disclosed in Patent Document 1. As shown in FIG.
As shown in FIG. 13, in this system, data transmitted from the gaming machines (gaming machine, safe, prepaid card vending machine, etc .: not shown) to the terminal device is transmitted for each data type through a dedicated communication line. Therefore, a large number of communication lines are required between the gaming machines and the terminal device, and wiring of extremely complicated communication lines is performed. The data accumulated from the gaming machines in the terminal device is converted into serial data and transmitted to a management computer (corresponding to a hall computer). Since a large number of communication lines are required for one game device, the number of game devices that can be connected to one terminal device is limited to four or less, and it is necessary to provide a plurality of terminal devices on the island. . Therefore, the data of the terminal device in the island is further accumulated in the relay terminal device and transmitted to the management device. In other words, the terminal device and the relay terminal device serve as an island computer. The administrator grasps and manages the operation data of the gaming machines with a management computer connected to the management device.
Conventionally, the gaming machine and each peripheral device are each connected to a management device with its own communication line, and the wiring of the communication line inside and outside the island has been complicated, but this system at least performs data communication outside the island. It is excellent in that the data of the gaming machine and the data of peripheral devices can be serially transmitted through the same communication line and can be managed collectively including the data of peripheral devices other than the gaming machine.
However, since game machine data and data of various structures of peripheral devices are transmitted to the island computer via individual communication lines, the types of data that can be transmitted to the island computer are the built-in data processing software and connection terminals. For example, if the image data of the surveillance camera is further transmitted to the island computer, it is necessary to provide extremely complicated island wiring such as increasing the number of island computers.

Further, a management system disclosed in Patent Document 2, for example, has an island computer provided with a data storage function and redundancy in data storage.
FIG. 14 is a configuration diagram of the game hall management system disclosed in Patent Document 2. As shown in FIG.
As shown in FIG. 14, in this system, each gaming device has a computer, and the computer stores the operating data of each gaming device via an island network (LAN: Local Area Network). Send to computer. The island computer sends the game machine operation data sent from the computer to the hall computer via the LAN in the hall, stores these data, and detects whether these data are normal. It has a function to do. The hall computer stores the operation data of the gaming machines transmitted from the island computer, and generates information necessary for gaming hall management and provides it to the manager.
This system is designed to transmit game machine data and peripheral device data on both the island and outside islands by forming a LAN, and the data storage is distributed between the hall computer and the island computer. It is excellent in point. However, similar to the technique of Patent Document 1, since the data transmission / processing method of gaming machines and gaming peripheral devices are different, a computer for unifying this is necessary for all gaming machines and gaming peripheral devices, The manufacturing cost of each gaming machine and game-related equipment increases.

In addition, there are a plurality of game halls to be managed and managed, and as a system for collectively managing these game halls, for example, Patent Document 3 collects operation data of a plurality of game machines from the game hall via the Internet and manages them. A system is disclosed.
FIG. 15 is a configuration diagram of a game hall management system disclosed in Patent Document 3. As shown in FIG.
As shown in FIG. 15, in this system, the hall computer of each gaming hall collects operating data of gaming machines and transmits it to the system server via the Internet. The system server stores operation data of gaming machines in affiliated gaming halls. The administrator accesses the system server from the management unit via the Internet and grasps the management status. In this system, the system server that stores data excludes unauthorized access from the outside with a firewall, but the data itself is not encrypted, and confidentiality / integrity / authentication, data generation denial prevention In addition, the aspects of prevention of spoofing and secret management of assumed data are insufficient. In particular, in order to allow access by a third party, it is necessary to keep who records what data can be accessed, and the system that has been accessed remains, but the system disclosed in Patent Document 3 lacks this point. In addition, sharing data with a third party is not safe and secure.

In the system disclosed in Patent Document 3, it is unclear whether an island computer exists in the data transfer system in the hall, but the island computer is clearly deleted to simplify the data transfer system in the hall, and A system capable of collective management of game halls is disclosed in Patent Document 4.
FIG. 16 is a configuration diagram of a game hall management system disclosed in Patent Document 4. In FIG.
As shown in FIG. 16, each gaming machine includes a WEB server in the gaming machine itself, and stores operation data, sales information obtained by processing these, and the like in a memory. Each gaming machine in the game hall is connected to the network by Ethernet (registered trademark), and is connected to the Internet via a router. The administrator accesses each gaming machine of all the game arcades of the affiliated system from the manager terminal via the Internet, and grasps the operation data. Further, a personal computer (personal computer) for managers is also connected to the network in the hall so that the operating state of the gaming machines in the gaming hall can be grasped. That is, the hall computer function is distributed to the gaming machine, the personal computer, and the router. This system is characterized in that the setting of the game play rate etc. of the gaming machine can be instructed from the administrator's personal computer, but it is also excellent in that the system is simple.
However, the technology related to SSL encryption on the Internet is not disclosed in the same manner as the system disclosed in Patent Document 3, and a function for monitoring fraud and data tampering by sharing data with industry groups and monitoring organizations. Does not have. Moreover, there is no defense for eavesdropping in the hall.
Furthermore, when managing data including many peripheral devices other than gaming machines, the WEB server as described in Patent Document 3 and all gaming machines must have data storage / processing functions. If you use the island computer or hall computer to process and store the data, the efficiency will be better and the overall capital investment will be less. Further, as will be described later, when processing a large amount of monitoring camera data or encrypting data, this system lacks data analysis processing capability.

  There are many proposals for surveillance camera systems in gaming halls. Regarding centralized management of gaming machine operation data, for example, Patent Document 5 discloses a system that stores video of surveillance cameras in association with the number of game machine balls. Is disclosed. However, this system is not preferable from the standpoint of protecting the portrait right of the player because the image of the surveillance camera is stored without being encrypted.

All of the above systems are not only problematic in the amount of information obtained by collecting data or the complexity of the communication wiring equipment for collecting data, but the integrated data is the management of the game hall.・ Provided only to managers and does not belong to the game hall, but is involved in the management, operation, supervision, maintenance, security, etc. of the game hall (hereinafter, these parties are collectively referred to as third parties). However, there is a big problem that these third parties are not a system that can share data with the management / administrator of the game hall even though it requires the operation data of the gaming machine and the game related equipment.
Management and operation of gaming halls include not only employees belonging to gaming halls, but also manufacturers (manufacturers) of gaming machines and gaming related equipment, gaming machine maintenance contractors, gaming machine related equipment (for example, gaming card vending machines) ) Management companies, security companies, etc., are involved, but each company must obtain the necessary information in the game hall through its own route.
In addition, the oversight body of the gaming machine only inspects the regulation items of the gaming machine regulated by the law such as the game play rate of the gaming machine at the time of the type testing of the gaming machine, and the subsequent unauthorized modification etc. in the gaming machine hall The situation is that the inspection cannot be performed in the operating state.

  In addition, as a method for displaying information for quickly determining the management status, for example, Patent Document 6 discloses a system in which a real-time production status (in-process status of products in each process) is virtually displayed in a factory. ing. However, this system is not a system that collectively manages a large number of factories via a hierarchical network, and cannot generate virtual data on demand from operation information of all series halls.

Here, it returns to description of FIG. 1 again.
A plurality of third party clients 14 are connected to the global network 12.
In addition to the management, managers and employees of the game hall 1, many related contractors and organizations are involved in the sales of the game hall 1. They are a maintenance machine, a manufacturer, a security agent, a prepaid card supplier, etc. The system of the present invention can also provide island information of all game halls to be managed and managed to these third parties. The third party client 14 is a terminal for these third parties to acquire island information from the administrator server / client 13 via the global network 12. As will be described later, in a system for encrypting information transmitted / received via the global network 12, a third party who is a recipient of information is authenticated by a certificate authority. The certificate authority server / client 15 of the certificate authority to be authenticated is connected to the global network 12.

As described above, the system of the present invention transmits and receives important information including a moving image of a player photographed by a surveillance camera via the global network 12, so that information can be encrypted with a highly secure encryption method. It is essential. Next, encryption will be described.
The encryption method used in this system is based on the encryption common key encryption method (hybrid method) using a secret key, public key, and common key, and a certificate authority is installed to prevent impersonation.
FIG. 9 is a diagram showing a flow of information and an encryption key for explaining an encryption method using a secret key, a public key, and a common key.
As shown in FIG. 9, this encryption method is a hybrid method (encrypted common key encryption method) with the highest security. First, the information receiving side 21 generates a public key 22 / private key 23 pair. As for the public key 22 and the secret key 23, information encrypted with the common key 25 created based on the public key 22 is decrypted with the secret key 23.
The information receiving side 21 transmits the public key 22 to the information transmitting side 24 over the Internet. Based on this, the information transmitting side 24 generates a common key 25 using a hash function or the like, and encrypts the plaintext information 27 with the common key 25 to obtain ciphertext information 28.
In order to ensure a high level of security, the information transmitting side 24 encrypts this common key in block / packet units with a public key to generate an encrypted common key 26 and transmits this to the information receiving side. The information receiving side 21 decrypts the encrypted common key 26 into a common key using a secret key, and decrypts the ciphertext information 28.

The encrypted common key 26 encrypted with the public key 22 can be decrypted only by the private key 23 due to the nature of the public / private key pair. Even if the encrypted common key 26 and the ciphertext information 28 are stolen, A person who does not have the secret key 23 cannot decrypt it.
However, in the encryption system as it is, there is no method for confirming who sent the public key 22 on the information transmission side 24. In other words, if a person impersonates the person who should receive the information and another person generates a public / private key pair and sends the public key, the sender will send the information to another person who has been impersonated. Become. A certificate authority is required to prevent this impersonation.
When using a certificate authority, as will be described below, the information receiving side 21 sends a public key and a sender ID certificate to the certificate authority and requests a certificate. The certificate authority confirms / certifies, and returns the public key 22a with the certification data added to the public key to the information receiving side 21. The information transmission side confirms the certification data with the certificate authority and obtains a guarantee.

FIG. 10 is a diagram showing the flow of data, information and encryption in this system, and shows the flow from generation of data to generation of a virtual cipher hole by the administrator server / client 13.
In FIG. 10, the administrator server / client 13 and the third party client 14 correspond to the information receiving side 21 and the island computer 5 in FIG. As shown in FIG. 10, the administrator server / client 13 and the third party client 14 generate a public key 22 and private key 23 pair. The public key 22 is transmitted to the island computer 5 via the global network 12 or the like. At this time, in order to prove that the public key 22 is sent by the game hall manager / administrator or a third party authenticated by the certificate authority, the certificate authority is authenticated. The certificate authority confirms the certificate 30 by a predetermined method to authenticate the public key 22, and returns the public key 22 a added with the certification data to the information receiving side 13, 14 via the global network 12.
The management / administrator confirms the certification data with the certificate authority and obtains a guarantee. The certification authority is in charge of industry groups, third-party organizations and companies.

  The operation data of the gaming machine 2 and the game related equipment 3 arranged on each island 4 is transmitted and accumulated as plain text data 31 to the island computer 5 via the island network 11. Here, the RFID tag information is preferably pre-encrypted as will be described later. Therefore, the read data may be encrypted, and from the standpoint of protecting the portrait right, the image data of the surveillance camera is also included. It may be encrypted by a surveillance camera. Even in devices other than RFID tags and surveillance cameras, highly confidential data may be encrypted in each device. The island computer 5 processes the plaintext data 31 to generate plaintext island information 32. The island computer 5 generates a common key 25, encrypts the plaintext island information 32 using the common key 25, and forms ciphertext island information 33. Further, the common key 25 is encrypted with the public key 22 / 22a to be an encrypted common key 26. The ciphertext island information 33 of each island is transmitted to the administrator server / client 13 and the third party client 14 through the global network 12 together with the encryption common key 26 by the specific island computer 5T.

The administrator server / client 13 and the third party client 14 that have received the ciphertext island information 33 and the encrypted common key 26 decrypt the encrypted common key 26 with the secret key 23 to obtain the common key 25. The plaintext island information 32 is obtained by decrypting the ciphertext island information 33.
The information sent to the third party client 14 is different from the manager server / client 13 managed by the manager of the affiliated game hall, and the information sent to the third party client 14 is limited. The client 13 accumulates all island information of all game halls to be managed and managed, and the plaintext island information 32 is stored in the game hall management database 51 as business index management information and equipment facility management information 34. Further, the virtual cipher hall 35 generated by using the plaintext island information 32 is stored in the virtual cipher hall database 54.

  The moving image of the player of the surveillance camera included in the business index management information of the Hirabun Island information 32 is stored in the gaming hall management database 51 for a predetermined time and discarded from the viewpoint of protecting the portrait right of the player. The player's moving image is stored to check the moving image when there is an abnormality in the play rate of the gaming machine 2 and there is a suspicion that the game is illegally performed. The time should be determined as short as possible from such a viewpoint. Similarly, data that has been processed and encrypted, such as data processed to detect a player's gender, age, and unauthorized operation, has a limited storage time.

Even when a third party receives island information by the third party client 14 via the global network 12, the game hall manager basically receives island information by the manager server / client 13 as described above. Is the same. However, it is not necessary to disclose all information to a third party, and only information necessary for each job needs to be transmitted.
In order to implement such restrictions on transmission information, a third party obtains each identity, information desired to be obtained, and an authenticated public key from the certificate authority, and sends them to the island computer 5. On the other hand, island information is encrypted with a different common key for each piece of information. Therefore, the encrypted common key encrypted with the public key can identify the third party and the information, so that the island computer 5 receives the authenticated public key and encrypts and transmits the necessary information to the third party. At the same time, it is possible to keep a record of which information is sent to whom.
From the viewpoint of ensuring the confidentiality of data, it is desirable that the encryption is performed at or near the data generation source. However, from the viewpoint of processing data, the amount of data processing increases due to data encryption / decryption. In this embodiment, the island information is encrypted by the island computer 5 and the encrypted data is collected and processed by the administrator server / client 13, but the plaintext island information is collected and processed in the specific island computer 5T and encrypted to be global. Transmission to the network 12 is also possible. In any case, it is essential that information transmitted and received via the global network 12 is encrypted.

FIG. 11 is a block diagram of an example of an encryption method using a real-time encryption system.
FIG. 11 shows what is called MRT encryption. Data (plaintext data) 102 to be encrypted on the data transmission side 101 is encrypted by the key generation / shared unit 105 through the processing of the random number generation unit 103 and the irreversible function group 104. A key is generated, converted to real-time encryption by the stream encryption unit 106, and transmitted to the data reception side 107 as ciphertext data 108.
The common key of this system can be changed for each unit (packet or block) of information to be encrypted, and is an MRT cipher with a pasted encryption method, and specifies an administrator (receiver) that can be accessed for each information unit It can also be used. In addition, since the common key can be changed 1000 times / second or more, the “one time key” is effectively different for each piece of data that the common key encrypts, and selective decryption that allows only necessary and sufficient data to be transmitted is required. This enables high-speed and real-time cryptographic processing.

Each gaming machine is sealed with an RFID tag that is encrypted and recorded / updated with the unique individual identification information including the authorization information of the gaming machine and the public key of the gaming machine accreditation body and the related body that has been authenticated by a third party organization. -Shipped after mounting. The management information recorded in the RFID tag can be decrypted and read at any time using a reader for the RFID tag having the secret key of the public key issuing organization connected to the island network 5. The authorization condition includes an authorization number, the total number of steps of the game control program, important register data, and the like, including the results of the type test conducted by the maintenance agency. When the RFID tag is read, the game control program is checked, and the information is processed along with other island information as remodeling (unauthorized remodeling) information together with the installation, repair, and movement information of the gaming machine.
When using an RFID tag that can be added or rewritten, information such as installation, movement, repair, and disposal recorded in the RFID tag is handled as island information, and the check result of the game control program is written in the RFID tag. You may do it. The hall manager can read and store the island information as part of or all of this information as island information, with permission from the gaming machine accreditation body and related organizations. The gaming machine accreditation organization and related organizations, hall managers, affiliated companies, and industry organizations can share island information through the global network 12 and cooperate to monitor unauthorized modification.
Note that it is possible to have a system in which a gaming machine supervising organization takes the lead in generating a public key, and an RFID tag for each gaming machine encrypted with this public key is sealed, mounted, and shipped. The gaming machine maker receives the RFID with the encryption header of the supervisory authority, and the hall manager decrypts the RFID tag information with the key issued by the USB memory or IC card to read this, and the administrator server / Stored in the equipment device database 52 of the client 13. It can be used as the ultimate measure to prevent unauthorized modification by allowing hall management / administrators of gaming machines and distributors / repairers of used machines to detect unauthorized modifications of the gaming machines and track the performers.

  A unique ID number is assigned to all manufactured gaming machines and game-related equipment using an IPv6 (Internet Protocol Version 6) address, and life information from manufacturing to hall installation to repair to second-hand sales to destruction is played. Machine manufacturers, hall managers, industry organizations, foundations / safety electronic communication technology associations (Hotsukyo Co., Ltd.) can be monitored and managed, and illegal modification, illegal destruction, prevention of recycling, and monitoring can be done perfectly.

Next, the network will be described.
The centralized monitoring and management system of the gaming hall 1 of the present invention collects, analyzes, and analyzes the operation data of all gaming machines 2 and gaming-related equipment 3 in the affiliated gaming hall to be managed and managed by constructing a hierarchical network. Process and centrally monitor and manage. In the present embodiment, the hierarchical network has two layers: an island network 11 that is a network in the game hall 1 (first layer network) and a global network 12 that is a network outside the game hall 1 (second layer network). These two layers are connected by the global network connection means 42 having a bridge function of the specific island computer 5T. The network in the game hall 1 can be further multi-layered depending on how and at which stage the read data of the gaming machine 2, the game related equipment 3 and the RFID tag are collected, analyzed and processed.
In this embodiment, since information transmitted and received on the network is encrypted, from the viewpoint of ensuring the confidentiality of information transmission, encryption is performed as close as possible to the data generation source, and the gaming machine 1 and game-related devices 3 is also connected to the island network 11 directly by USB.
The global network 12 is generally the Internet. As for the Internet, it is of course possible to make a dedicated line by using a VPN (Virtual Private Network) which overlaps with the encryption of the present invention, but it is not necessary by the encryption on the island computer.
The island network 5 is constructed by a network capable of a data transfer method capable of real-time control. As a fieldbus or field network used in the FA (Factory Automation) field, etc., a control network CAN (Controller Area Network), a DeviceNet as an extension set of CAN, a LonWorks using a neuron chip, and a MOST for in-vehicle use (Media Oriented Systems Transport), LIN (Local Interconnect Network) with simplified CAN, or RTE (Real Time Ethernet (registered trademark)) with real-time control function added to Ethernet (registered trademark) that is widely used as a general LAN ) Etc. can be used.
The real-time control in this system does not have to be true real-time control by a real-time OS or a single task, as long as the data bandwidth, data transfer speed, data delay, etc. according to each application can be satisfied, for example, USB isochronous transfer, etc. As long as the so-called real-time transmission can be ensured.
However, the island network 12 is preferably USB. USB is a standard protocol that is currently widely used, and a USB bus compatible USB chip widely used for mobile phones, cameras, printers, DVDs, etc., is connected to this system, By using it for game-related equipment, it is possible to reduce the investment in amusement hall management facilities. In addition to USB, it is of course possible to use IEEE 1394, which is currently in widespread use, and it is also possible to use wireless USB, wireless LAN, and PLC (Power Line Communication).
Corresponding to the fact that the island network 12 is USB, both the gaming machine 2 and the game related equipment 3 connected to this use a USB compatible interface (a common interface including physical specifications such as Device Bay). May be provided). As the surveillance camera, a high-performance USB camera is commercially available and can be used as it is. The gaming machine 2 and game-related equipment 3 that do not support USB for data transmission / reception convert the input / output signals to the USB protocol via a bus converter or the like, and transmit / receive data to / from the island network 11.

When USB is used for the island network 11, both the gaming machine 2 and the game related equipment 3 correspond to the USB compatible interface, and the island network 11 is constructed by USB connection that enables hot plugging and power superimposition. A mobile phone, a camera, a printer, and a DVD using a USB interface can be connected to the island network.
Since the internal bus (in-board bus) of the gaming machine 2 is also made USB, there is a merit that it is possible to simplify complicated on-board wiring, so it is preferable to use a USB-compatible interface. At present, the CPU function and the memory capacity for controlling the game of the gaming machine 2 are limited in order to prevent the addition of functions beyond the functions defined by laws and regulations. Therefore, various functions that excite the fun of the game and monitor fraud are added to the game machines one after another independently from the CPU and memory that control the game, and various forms of signals are generated in the game machine. It is transmitted and received via complicated wiring. In order to simplify the wiring in such a complicated gaming machine, it is extremely useful to use a bus in the board of the gaming machine as a USB.
USB has four types of transfer modes: control transfer, bulk transfer, isochronous transfer, and interrupt transfer. Address control, transmission / reception of a large number of images and sounds, feedback control of motor, plunger, etc., and player, respectively. It can be used for interrupt transfer by operating the start lever and stop button, and it is possible to enhance functions such as hot-swapping and power superimposition, so that it is suitable as an in-board bus for gaming machines.

  The game-related equipment 3 other than the gaming machine 2 also has an internal bus made of USB to simplify internal wiring, enable hot plugging and power superimposition, and can be directly connected to the island network 11 made of USB. It is preferable to do.

The power supply voltage of the gaming machine 2 is conventionally 24V, but in the case of a 24V power supply, a large number of transformers that step down from a commercial power supply of 100V or 200V to 24V are required, and a large amount of capital investment is required, and power supply wiring is complicated There was a problem of becoming. However, the fundamental problem of the 24V power supply by the transformer is that the capacity of the power transformer is limited, so that the voltage fluctuates beyond the allowable range due to fluctuations in the power used, and the gaming machine malfunctions. Therefore, it is preferable that the power source of the gaming machine is commercial 200V.
Moreover, it becomes easy to use PLC by removing a transformer. An information signal is superimposed on a commercial 100V or 200V power line supplied to the gaming machine 2 and the island computer 5 as a high frequency signal, and a power line superimposed signal modulation / demodulation means for separating the high frequency superimposed information signal is added to the power line.
Further, it is preferable that the operating data transmitted from the gaming machine 2 to the island computer 5 include the power supply voltage, power consumption, CPU power supply voltage, and the like of the gaming machine 2.
The commercial power supply may be 100V, but 200V is preferable because the current can be reduced and voltage fluctuation can be suppressed when the same power is supplied.

  It goes without saying that the embodiment of the present invention described above can be variously modified within the scope of the technical idea of the present invention.
