Description

  The present invention relates to a gaming machine, a gaming system, and a game hall management device.

  Conventionally, communication from a gaming machine such as a pachinko machine or pachislot machine to an external device such as a CR unit or a sand that is connected to each gaming machine is generally based on a relay system using a relay (for example, Patent Document 1).

  The reason why the relay system has been generally used is that the interpretation that game machines should not always be connected to external devices under the laws on customs business and the law on the appropriateness of business (custom law) It was because it was made. In other words, in the relay system, the relay is physically opened and closed each time it is transmitted, so that the constantly connected state between the gaming machine and the outside is not maintained.

  On the other hand, in recent years, the optical communication system is expanding as a communication form. In Patent Document 2, one data analysis device is connected to dozens of gaming machines through optical communication, and gaming data (the number of detected out balls, the number of detected safe balls, the number of operating hours, the total start-up time) It is disclosed that the number of entered balls, the number of starts, the total number of winnings, the number of winning prizes) are transmitted to the data analysis device and displayed on the data analysis device.

JP 2008-173202 A JP 09-051984

  However, when the relay method is used as in Patent Document 1, the amount of data transfer is small, and there are switching contacts in the signal path, so noise is easily added, encryption is difficult, and a relay is required for each type of signal to be transmitted. Therefore, there is a problem that the relay is a one-to-one communication, which causes an increase in cost, and is not scalable and cannot flexibly respond to user requests.

  Further, in Patent Document 2, it is described that it is not easy to perform integrated management with a hall computer using a wireless system due to problems of radio interference and transmission reliability (see paragraph 0004). We paid attention to the fact that the optical communication method was adopted, and the signal could be transmitted without always connecting the gaming machine and the external device as in the relay method.

The game data transmitted to the device 50 is referred to as second game data.

  The gaming machine 10 is a game device such as a so-called pachinko machine 10a and a pachislot machine 10b. The game medium management device 20 is a so-called CR rental unit or a ball lending unit called a medal sand (sand), and the game medium such as a ball game ball or a medal is lent to a player when a valuable value is input. It has become. The game medium management device 20 is provided on the side of the gaming machine 10. As shown in FIG. 1, in the case of the pachinko machine 10a, the gaming medium management device 20 is installed on the left side of the casing 15 of the gaming machine 10, and in the case of the pachislot machine 10b, the gaming medium management device 20 is connected to the gaming machine 10. Installed on the right side of the housing 15. In this embodiment, the game medium management device 20 is configured to be installed on either side of the gaming machine. The above-mentioned ball rental unit is provided with a payout unit for game media such as medals. When the gaming machine 10 increases the gaming value (credits, etc.) of the gaming machine 10 by inserting the gaming media as described above, the gaming media management device 20 is also provided with such a payout unit. Also good. Further, when the gaming value of the gaming machine 10 is increased by the lending operation in the gaming medium management device 20, the above payout unit may not be provided. That is, since it is not necessary to increase the gaming value of the gaming machine 10 via the gaming medium, a payout unit is not necessary. In this case, since it is not necessary to consider the difference of game media according to the gaming machines, the game media management device 20 can be easily applied to both pachinko machines and pachislot machines.

Here, game data will be described. Data output to the outside in pachinko games and pachislot games includes the following. That is, the game data in the pachinko game is a jackpot signal, a ball signal, a start signal, a payout signal, and the like. The game data in the pachislot game includes medal insertion signal output, medal payout signal output, BB (Big Bonus) winning signal, RB (Regular Bonus) winning signal, CBB winning signal, CBB winning signal, lower door opening signal, and the like.

That is, the control board 11 transmits game data to the game machine side connection terminal board 12 by an optical signal. In a gaming machine that executes a pachinko machine or a pachislot machine, the control board 11 incorporates a control circuit that determines payout in the game. In this type of gaming machine, the input of signals to a main control board such as the control board 11 is generally restricted from the viewpoint of countermeasures against fraud. In addition, from the same viewpoint, it is common that input of signals to the gaming machine itself is also restricted. Therefore, communication between the control board 11 and the gaming machine side connection terminal board 12 is limited to one direction from the control board 11 to the gaming machine side connection terminal board 12. Although not described in detail, communication between the control board 11 that executes the game and other peripheral boards is restricted to only one direction from the control board 11 to other peripheral boards in the gaming machine 10. Has been. In this way, the gaming machine 10 is configured such that no signal is input to the control board 11. That is, the control board 11 does not have a function of a receiving unit for receiving an external signal. Further, the gaming machine side connection terminal plate 12 emits an optical signal from the control board 11 to the outside of the housing 15 as signal light. In other words, for wireless communication between the gaming machine and the outside, optical wireless communication is limited to only one direction from the gaming machine to the outside. As described above, the gaming machine 10 is connected so as to be able to perform data communication with the outside. However, in the data communication, no signal is input to the gaming machine 10 from the outside.

And a gaming machine side connection terminal board 12 that is emitted to the outside of the housing 15 by the unit 13, and the signal light emitted to the outside is wired to the external device (game medium management device) 20 so that data communication is possible. The connected converter 30 receives the light and then converts it into an electrical signal.

  In addition, the gaming system 50 includes the gaming machine 10 as described above, an external device 20 provided individually in the gaming machine 10, and a game hall management device 50 connected to the external device 20 so as to be able to perform data communication. The external device 20 receives game data from the converter 30 and transmits the received game data to the game hall management device 50.

  In addition, the game hall management device 50 that manages game data from a gaming machine is emitted as signal light from the gaming machine 10 to the outside of the casing 15 of the gaming machine 10 and is externally provided on the gaming machine 10 individually. The game data received by the converter 30 connected in a wired manner so that data communication is possible, converted into an electrical signal, and output from the external device 20 is received and stored.

  In other words, the gaming system 100 outputs the game data to the gaming machine 10 as a serial signal from the control board 11 to the gaming machine side connection terminal board 12, and a signal based on the gaming data received from the control board 11 A step of emitting light from the gaming machine side connection terminal board 12 to the outside of the housing 15 by the light emitting unit 13 is executed. In addition, the gaming system 100 receives the signal light emitted from the gaming machine side connection terminal plate 12 to the converter 30 that is arranged in the traveling direction of the signal light and is wired to the external device 20 so that data communication is possible. Then, the step of converting the signal light into an electrical signal is executed. In addition, the gaming system 100 causes the external device 20 to execute a step of receiving game data from the converter 30 and a step of transmitting the received game data to the game hall management device 50. In addition, the gaming system 100 causes the game hall management device 50 to execute a step of receiving and storing game data output from the external device 20.

  With such a configuration, the game data is output as a serial signal from the control board 11 to the gaming machine side connection terminal board 12, and is emitted as signal light from the gaming machine side connection terminal board 12 to the individual converter 30 of the gaming machine 10. The Thereby, it is not necessary to provide the relay used conventionally for every type of game data in the game machine side connection terminal board 12, and it is only necessary to provide one device that modulates a serial signal into signal light. The converter 30 on the signal light receiving side may be provided with one device that receives and demodulates the signal light. As a result, the cost can be reduced as compared with the conventional gaming machine 10. Moreover, since optical communication is used, expandability can be expected. In addition, since optical communication is used, physical operation does not occur unlike relays, so that failure and noise generation can be reduced. Furthermore, the data transfer amount can be increased compared to the conventional case. More specific description will be given below.

The time measuring unit 403 measures the time elapsed since the power-on of the display device 40 that is turned on at the same time when the gaming machine 10 is turned on, and displays display device time information based on the time to the game data adding unit 402. Send. The storage unit 404 stores unique display device identification information for each display device 40. That is, the game data adding unit 402 adds the display device time information and the display device identification information to the game data to generate game data. Therefore, display device identification information for identifying the display device 40 and display device time information are added to the game data. The transmission unit 405 transmits the second game data to which the display device identification information and the display device time information are added to the game hall management device 50.

(Amusement center management device)
The game hall management device 50 has a microcomputer as a main component. The microcomputer causes the game room management device 50 to include various processing units (processing functions) by causing the main CPU to execute processing programs stored in ROM or RAM. As shown in FIG. 6, the game hall management device 50 includes a reception unit 501, a game data determination unit 502, a storage unit 503, and a notification unit 504. The receiving unit 501 receives the first game data from the game medium management device 20 and the second game data from the display device 40. The game data determination unit 502 determines whether an illegal act is being performed based on the received first game data and second game data. The storage unit 503 stores data for the game data determination unit 502 to determine fraud. Specifically, an identification information table in which gaming machine identification information, control board identification information, and display device identification information are associated with each other is stored. The storage unit 503 stores a set time table in which a winning combination is associated with a set time set for each winning combination.

(Identification information table)
Here, the above-described identification information table and set time table will be described.
As shown in FIG. 7, the identification information table has a gaming machine ID column, a control board ID column, and a display device ID column. In the gaming machine ID column, gaming machine identification information is stored in advance. Control board identification information is stored in advance in the control board ID column. Display device identification information is stored in advance in the display device ID column. Thus, the gaming machine identification information, the control board identification information, and the display device identification information are associated in advance by the identification information table. The gaming hall management device 50 includes gaming machine identification information and control board identification information included in the received first game data, gaming machine identification information, control board identification information, and display device identification information included in the second game data. The two are compared with the identification information table to determine whether or not they are inconsistent.

(Set time table)
As shown in FIG. 8, the set time table has a winning combination column, a set time column, a previous time column, and a current time column. Although not shown, the set time table is prepared for each of a plurality of gaming machines. In the winning combination column, the type of winning combination is stored in advance as specific game information indicated by information that can be included in the game data. In the set time, a set time for confirming whether an illegal act is performed is stored in advance. In the previous time field and the current time field, the latest two times of the time in which the winning combination set in the winning combination column is included in the game data are stored. If the time difference between these two latest times is shorter than the time set as the set time, it is determined that an illegal act is being performed.

(Operation of game hall management device)
Next, the operation of detecting fraud in the game hall management device 50 will be described using a flowchart.
As shown in FIG. 9, first, the game hall management device 50 determines whether or not the first game data and the second game data are received from the game medium management device 20 and the display device, respectively (S100). . If at least one of them has not been received (S100: NO), the process returns to step S100. On the other hand, if both have been received (S100: YES), it is determined whether the identification information matches (S101). Specifically, the gaming machine identification information and control board identification information included in the first game data, the gaming machine identification information, control board identification information and display device identification information included in the second game data, and the identification information table are stored in advance. The set gaming machine identification information, control board identification information, and display device identification information are collated to determine whether they match. If the identification information does not match (S101: NO), it is determined whether all the identification information of the first game data and the second game data exists in the identification information table (S102). If it does not exist (S102: NO), a fraud notification process is performed (S107). The cheating notification process can include, for example, display / audio output in the game hall management device 50, special operation of the audio output / direction device in the corresponding gaming machine 10, and the like. Although not shown, when the identification information between the first game data and the second game data does not match, the process may proceed to step S107 to perform a fraud notification process.

  On the other hand, when all the identification information of the first game data and the second game data exists in the identification information table (S102; YES), the identification information table is updated based on the received game data. (S103). For example, it is a normal process when the gaming machine 10 is connected to a different display device 40. Note that the update process of the identification information table may be performed only when the game data includes special information. For example, when the gaming machine 10 is connected to a different display device 40, the gaming machine 10 may include information indicating that only the first game data. Thereby, it can discriminate | determine that it is not an unauthorized act more reliably.

  In step S101, if the identification information matches, or after step S103, it is determined whether the time information matches (S104). Specifically, the gaming machine time information included in the first game data is compared with the gaming machine time information and the display device time information included in the second game data to determine whether or not they match. If they do not match (S104: NO), the process proceeds to step S107, and a fraud notification process is executed. In addition, as an illegal act that can be considered when the gaming machine time information and the display device time information do not match, the player may turn off the power source of the gaming machine 10 momentarily by an illegal radio wave, and aim at a random number period or the like related to determination of the gaming result. There is a so-called instantaneous disconnection. When such a fraudulent act is performed, the gaming machine time information from the gaming machine 10 is the information after the momentary interruption, and therefore it can be detected because it does not match the display device time information.

  On the other hand, when the time information matches (S104: YES), the set time table update process is executed for the gaming machine 10 corresponding to the game data (S105). Specifically, if there is a winning combination (specific game information) set in the set time table in the received game data, the time information included in this game data is set to the current time corresponding to the winning combination in the set time table. Set in the time field, and set the time information set in the current time field in the previous time field. Thereafter, regarding this winning combination in the set time table, it is determined whether or not the difference (winning interval) between the time information in the current time column and the time information in the previous time column is shorter than the set time (S106). If the winning interval is longer than the set time (S106: NO), the process returns to step S1. If the winning interval is shorter than the set time (S106: YES), the process proceeds to step S107, and the fraud notification process is executed. After completing the execution of step S107, the process returns to step S1.

(Communication LSI)
Here, the communication LSIT1 (the gaming machine side communication LSIT33, the converter side communication LSIT34) will be described. The communication LSIT1 has a microcomputer as a main component. The microcomputer causes the game room management device 50 to include various processing units (processing functions) by causing the main CPU to execute processing programs stored in ROM or RAM. As shown in FIG. 10, the communication LSIT 1 has a function of encrypting game data and transmitting it to the outside. That is, the communication LSI T1 includes a receiving unit T2 that receives game data to be transmitted from the control board to the outside, an encryption unit T3 that encrypts game data received by the receiving unit T2, and an encryption unit T3. And a transmission unit T4 for transmitting the converted game data.

  The receiving unit T2 receives game data serially. Thereby, it is possible to prevent an increase in signal lines caused by mounting the communication LSIT1 on the control board.

  The receiving unit T2 includes a UART unit T11 having a UART communication function, an SPI1 unit T12 and an SPI2 unit T13 having an SPI communication function, and an I2C unit T16 having an I2C communication function. That is, the communication LSIT1 includes four receiving units T2, and the receiving unit T2 can receive game data in three types of communication modes. As a result, the communication LSIT 1 can receive game data in a plurality of communication modes, and therefore can select a communication mode that is optimal for various control devices and communication environments, so that it is highly versatile.

  Note that the communication LSIT1 may include a receiving unit T2 having a communication function according to a communication standard other than the UART communication function, the SPI communication function, and the I2C communication function. That is, the communication LSIT1 only needs to include one or more reception units T2 having one or more types of communication functions.

  The transmission unit T4 transmits game data serially. As a result, the number of signal lines for communication can be reduced as compared with the case of parallel communication, so that an increase in the outer diameter of the communication cable can be suppressed.

  The transmission unit T4 corresponds to the UART unit T11, the SPI1 unit T12, the SPI2 unit T13, and the I2C unit T16. That is, the communication LSIT1 includes four transmission units T4, and the transmission unit T4 can transmit game data in three types of communication modes. As a result, the communication LSIT 1 can transmit game data in a plurality of communication modes, and therefore can select an optimal communication mode for various control devices and communication environments, so that it is highly versatile.

  Note that the communication LSIT1 may include a transmission unit T4 having a communication function based on a communication standard other than the UART communication function, the SPI communication function, and the I2C communication function. That is, the communication LSI T1 only needs to include one or more transmission units T4 having one or more types of communication functions. In addition, the communication LSIT1 in the present embodiment is configured to include both the reception unit T2 and the transmission unit T4 because the UART unit T11, the SPI1 unit T12, the SPI2 unit T13, and the I2C unit T16 have a transmission / reception function. However, it is not limited to this. That is, the communication LSIT1 may include a reception unit T2 dedicated to reception and a transmission unit T4 dedicated to transmission. In the above communication standard, data modulation by the Manchester encoding method may be performed. That is, when applied to the present embodiment, in the gaming machine side connection terminal board 12, the gaming data encrypted and Manchester encoded by the gaming machine side communication LSIT 33 is modulated into the signal light by the signal light modulation unit 123 and the light emitting unit 13 It is emitted from. In the converter 30, the signal light received by the light receiving unit 33 is modulated into an electric signal by the electric signal modulation unit 301, and is modulated and decoded by the converter side communication LSIT 34 based on the Manchester code. Game data.

  The encryption unit T3 has an encryption function for processing game data with a conversion algorithm for conversion so that a third party cannot read without special knowledge. As the encryption function, encryption by a steganography method, a code method, or a cipher method can be employed. The steganography method is a method of recording a communication sentence such as a digital watermark that embeds game data in image data or the like in a place that is not visible to the public. The code method is a method of replacing words and phrases in correspondence with words / symbols determined in advance. The cipher method is a method of converting a communication sentence into an unreadable sentence by performing substitution or transposition for each one or more characters or bits according to a predetermined algorithm regardless of the meaning. Cipher systems include a common key encryption system that uses the same key for encryption and decryption, and a public key encryption system that uses different keys for encryption and decryption.

  According to the above configuration, since the received game data is encrypted and transmitted in the communication LSIT1, the encryption processing on the control board side that outputs the game data to the communication LSIT1 becomes unnecessary. As a result, the processing burden on the control board accompanying encryption is not increased. Furthermore, since the game data is transmitted in an encrypted state, secrecy is ensured during transmission, so that illegal acts caused by stealing game data during transmission and reading the contents can be prevented. As a result, fraud can be prevented without increasing the burden on the control board.

  Furthermore, the communication LSIT 1 according to the present embodiment has a decryption function for decrypting received game data in addition to the encryption function. In other words, the communication LSIT1 includes a receiving unit T2 that receives game data, and, when the game data received by the receiving unit T2 is plaintext, an encryption unit T3 that encrypts the game data, and a process received by the receiving unit T2. When the data is ciphertext, it has a decryption unit T5 for decrypting the game data, and a transmission unit T4 for transmitting the game data encrypted by the encryption unit T3 and the game data decrypted by the decryption unit T5. doing. Here, the decryption unit T5 may perform decryption using a common key based on a common key cryptosystem using the same key for encryption / decryption, or decryption using a secret key based on a public key cryptosystem.

  In the communication LSIT1 in the present embodiment, the AES unit T21 having an AES (Advanced Encryption Standard) function corresponds to the encryption unit T3 and the decryption unit T5. As a result, the communication LSIT1 can be encrypted and decrypted by one AES unit T21. Note that the communication LSIT1 may include an encryption unit T3 and a decryption unit T5 independently. Further, the communication LSIT1 may be configured to encrypt and decrypt by a plurality of types of encryption methods.

  Note that the encryption unit T3 is preferably encrypted by a common key block encryption method. In this case, since logical compression is possible in encryption, it is easy to implement, and the data path can be easily divided into predetermined bits, so it can be flexibly supported from small packaging to high-speed processing. It can be LSIT1. The encryption unit T3 preferably has an AES encryption algorithm as a common key block encryption method. In the communication LSIT1, the AES unit T21 has an AES function of a common key block encryption method. As a result, the communication LSIT 1 has high encryption strength and performs all internal processing in units of bytes, so that the computation efficiency during encryption processing is high, so the time required for encryption and decryption processing is shortened. Can be timed.

  Further, the communication LSIT1 includes a storage unit T6 that rewriteably stores a common key used for encryption and decryption, and a dedicated terminal connected to a common key writing device (not shown) that writes the common key to the storage unit T6. T221. Accordingly, when writing or rewriting the common key, it is necessary to connect to the dedicated terminal T221 of the common key writing device, so that it is possible to prevent an illegal act due to the change of the common key. Moreover, a common key can be changed for every product and every model. Therefore, even if the common key is known for one product, it is possible to prevent an illegal act from being performed on other products.

  As described above, the communication LSIT1 (gaming machine side communication LSIT33, converter side communication LSIT34) has a function of executing encryption and decryption, but is not limited to this, and the gaming machine side Only the encryption function may be provided in the gaming machine side communication LSIT 33 of the connection terminal board 12, and only the decryption function may be provided in the converter side communication LSIT 34 of the converter 30.

(Modification)
For example, the functions such as the communication LSIT 33 of the gaming machine side connection terminal board 12 may be provided on the control board 11 and the gaming machine side connection terminal board 12 may be eliminated.
Specifically, as shown in FIG. 15, the gaming machine 210 has a control board 211, and optical wireless communication is performed between the optical cable 214 drawn from the control board 211 and the optical cable 231 drawn from the converter 230. It has been made.
The control board 211 includes a communication LSIT 233 and a modulation unit 223. Moreover, although not shown in figure, the control board 211 has each part of the control board 11 in this embodiment, and each part of the game machine side connection terminal board 12 (refer FIG. 2). The game data encrypted in the communication LSIT 233 is transmitted to the modulation unit 223. The game data is modulated into an optical signal by the modulation unit 223 and output to the optical cable 214.
The distal end portion of the optical cable 214 and the distal end portion of the optical cable 231 are fixed on a terminal board 260 provided in the gaming machine 210. Such a terminal board for external connection is stipulated by the rules of pachinko machines and pachislot machines to be provided in gaming machines and is always necessary. Therefore, in the present modification, the terminal plate 260 is provided on the back side of the gaming machine 210 in the case of a pachinko machine, and is provided in the casing of the gaming machine 210 in the case of a pachislot machine. However, if there is no such rule restriction, the terminal board 260 can be eliminated and the optical cable 214 can be led out of the housing directly from the control board 211.
