Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game information medium (for example, an IC card), and more particularly to a game information medium which is used in a game arcade and can record and display various game information and the like.

[0002]

2. Description of the Related Art Generally, as a game arcade equipment using a game medium, for example, a pachinko game machine, an arrange ball machine, a sparrow ball machine, a throttle machine using a medal (turned-type throttle game machine), and a ball are used. There is a throttle machine (turn-type throttle game machine) and the like. Conventionally, for example, when performing a pachinko game, a player throws money into a ball lending machine at a game store, converts it into a desired number of balls, possesses the converted game balls, selects a gaming machine, and plays a game. . In addition, the banknotes have been converted into money to some extent, and the money has been thrown into a tama ball lending machine attached to the gaming machine to lend a ball while playing the game. Recently, there is a card using a prepaid card (game card) in order to eliminate the above-mentioned troublesomeness of ball lending. This is because the player purchases a card in which the amount of money is recorded in advance and uses it for the game, and in the process of using it, it is converted so that it can be used for the game within the range of the amount of money recorded on the card, and the converted amount is The amount recorded on the card is reduced. Specifically, a gaming machine that uses a card to play a game, such as a pachinko gaming machine or a slot machine (a so-called pachislot gaming machine), is a game ball in which the valuable value (amount of money) recorded on the card is the gaming value, It is converted into game coins and played. Such prepaid cards include magnetic cards.

Some cards of this type clearly show the recorded game information so that it can be visually recognized by the player. For example, there is one in which a display unit is provided on the surface of the card, and the game information can be displayed on the display unit by utilizing the powder of sand iron (for example, a so-called house card). On the other hand, many prepaid cards do not have a display part, and some of the remaining amount can be judged by making a very small hole in the card. Further, the prepaid card can be inserted into the ball lending machine to visually recognize the remaining amount information (remaining amount of money) accurately, but this is extremely troublesome for the player.

[0004]

However, such a conventional game card has the following problems. (B) With conventional prepaid cards, there is no display of recorded information (for example, amount information), and the remaining amount can only be judged by making a very small hole in the card, and the remaining amount can be visually confirmed accurately. I couldn't do it and it was inconvenient. In addition, inserting the prepaid card into the ball lending machine and attempting to visually visually recognize the remaining amount information (remaining amount of money) is extremely troublesome for the player. (B) Conventional game cards (eg prepaid cards)
Then, it has been easy to read the recorded information (for example, money amount information) relatively easily and to write the illegal information (for example, money amount information). (C) In addition, in order to display the game information recorded on the card, for example, there is one in which a display unit is provided on the front surface of the card, and the game information can be displayed on the display unit by using sand iron powder. . However, with this card, the number of balls held can be displayed by using the powder of sand iron, which is inconvenient as there is little display information.

(D) In order to solve such a problem, it has been proposed to use an IC card as a game card instead of using a conventional magnetic card. However, in the case of using the IC card, However, if the memory that directly stores the information can be accessed from the outside, the information can be written / read to / from the memory and the information may be tampered with. (E) Some IC cards display game information recorded on the card (for example, Japanese Patent Laid-Open No. 5-156).
No. 55). In this technique, an IC card is provided with an information display section so that the balance and the number of balls held can be displayed.
However, this is inconvenient because it can display only limited information (the number of coins and the balance). Moreover, a simple protocol is used for writing / reading information, and if the memory information is directly written / read out from the outside, the information may be tampered with.

(F) In addition, the IC card described in the above publication is capable of subtracting the amount used for ball lending from a fixed amount prepaid and only storing the number of balls held for the sake of settlement. , It is not a type of card that can be used for complete amusement hall facilities that use IC cards (that is, a gaming system that is capable of earning payouts, converting to a stored amount, etc.). Recently, a complete amusement hall facility using an IC card has been proposed, and when the IC card described in the above publication is applied to such a system, it is absolutely impossible to judge whether or not the information has been written normally. Since the game value (amount of money) and the game value (number of balls held) are frequently increased and decreased, there is a problem that the reliability of information is lacking. (G) Further, the idea of a limit value of information to be written (a limit value to which a large amount of money cannot be added) is based on the IC described in the above publication.
It wasn't on the card and was less secure. (H) Furthermore, the concept of the access right to the information in the card to the terminal device is not present in the IC card described in the above publication, there is a possibility that the information cannot be handled correctly, and the safety is lowered, and the information is further reduced. There was also a risk of breaking.

Therefore, the present invention has been made in view of the above-mentioned problems, and provides a game information medium which is highly safe for writing and reading information and which can easily display information desired by a player. It is an object.

[0008]

To achieve the above object, the game information medium according to the invention of claim 1 can record at least information related to the game such as valuable value information, game value information, security information and the like. Related information recording means,
Information writing means for writing information to the game-related information recording means based on a command from the mounted terminal device, and information read from the game-related information recording means based on a command from the mounted terminal device, the mounted terminal It is characterized by comprising information reading means for sending to the device, and information display means for displaying predetermined contents of valuable value information or game value information recorded in the game related information recording means.

As a preferred mode, for example, as described in claim 2, the information writing means is provided with a writing confirmation means for judging whether or not the information can be accurately written in the game related information recording means. Good. For example, as described in claim 3, the information writing unit determines a limit value for limiting the write information to the game related information recording unit, and the write information to the game related information storage unit exceeds the limit value. If there is, a writing restriction unit that rejects writing of information based on a command from the mounted terminal device may be provided.

For example, as described in claim 4, the information writing means is written in the game-related information recording means based on a command from the mounted terminal device, and the mounted terminal device is permitted to access. It may be provided with a write restricting unit that determines whether or not the information is the specified information and rejects the writing of the information if the information is not the specified information. For example, as described in claim 5, in the information reading means, the read information from the game-related information recording storage means based on a command from the mounted terminal device is defined information that the mounted terminal device is permitted to access. It is also possible to have a read restricting means that determines whether or not there is any information and refuses to read the information if the information is other than the prescribed information.

For example, as described in claim 6, there is provided selection means capable of selecting predetermined game-related information by the operation of the player, and the information display means displays the predetermined game-related information selected by the selection means. You may do it. For example, as described in claim 7, the valuable value information stored in the game-related information recording means includes money amount information and accumulated coin amount information in which the number of balls owned by the player is converted at a predetermined exchange rate. The value information is the number of possessed balls information to be added or subtracted based on the course of the game, game machine number information, game shop information,
Game-related information selected by the selecting means, including date-of-use information, expiration date information, and today's balance information that calculates the difference between the amount of money used for today's game and the amount of money obtained by adjusting the number of balls acquired The information includes at least one or more of amount information, accumulated amount information, number of owned balls information, expiration date information, today's balance information, gaming machine number information, game shop information, and date of use information. You may do it.

(F) IC Card Access Right Status FIG. 10 is a view showing the access right status of each card information of the IC card 200. In the figure, the left column shows the card information in the IC card. Among the terminal devices, those with access to write or read the card information are ○.
This is indicated by a mark. For example, the card number can be written / read at the card company 2, but the access right is set so that it can only be read at each terminal device. In this case, the card number corresponds to the write information, and corresponds to the regulation information that the card company 2 is permitted to access (write access). The card number corresponds to the read information, and corresponds to the regulation information that the card issuing machine 23 is permitted to access (read access). Hereinafter, the same applies to other card information, which corresponds to write information / read information along with the contents shown in FIG.

Next, the operation will be described. 11 to 17 are flowcharts showing the control program of the IC card 200. This program is executed not only when the IC card 200 is inserted into the card reader / writer, but also when the card is carried and operated. A. Main program of IC card (FIGS. 11 to 13) When the program starts, it is first determined in step S10 whether or not the mode is the offline mode. This is to determine whether or not the card is inserted into the terminal device (the terminal device to which the card is attached) and there is a power supply signal (supply of electromagnetic waves). The power supply signal is wirelessly supplied from the card reader / writer when the card is inserted into the card reader / writer of the terminal device.

(A) In the case of the offline mode (when carrying the card) This corresponds to the case where there is no power supply signal.
The determination result of 10 is YES, the process proceeds to step S12, and the process corresponding to the card operation of the player is executed in the subsequent steps. The power supply of the card is the built-in solar cell 2
It is supplied from 09. At this time, the clock signal of the clock circuit 206 (having a slow clock frequency) is supplied to the CPU 213 because it is not inserted into the card reader / writer. On the other hand, when inserted in the card reader / writer, the clock signal (having a high clock frequency) from the clock extraction circuit 202 is supplied to the CPU 213.

First, the RAM 215 is initialized in step S12, and it is determined in step S14 whether or not the value of the temporary counter is equal to or larger than a predetermined value (here, "5").
The temporary counter stores the information sent at the time of writing,
A counter that compares the written information, checks the terminal identification number transmitted from the attached terminal device if it does not match, and counts up the number of defects that is incremented by "1" if it does not match. If the counter reaches a predetermined value or more, the operation of the card is disabled. When the temporary counter is "5" or more, the process proceeds to step S16, and "cumulative abnormality" is displayed on the LCD 212. In this state, the card cannot be used at all, and the player cannot see the card information. Therefore, at this time, the card is shown to the attendant of the game shop, and the handling decision of the card is left to the attendant. For example, after talking with the player, a measure such as updating the card is taken.

When the temporary counter is less than "5", step S18, step S22, step S2
In step 6, it is determined whether the card has been issued, has been updated, or has been issued. Judgment of "Before issuing", "Updated", and "Issued" at each step is made by the card issuer number (terminal device identification number) stored in the card The machine number is attached. "Before issuing" = 55AA (provisional issuing machine number) "Updated" = 0000 (card inserted into the card updating machine 14 and collected) "Issued" = 5151 (true issuing machine number) Card company 2 The delivered card includes an encrypted security code, an encrypted card number, an encrypted temporary card issuer number, an encryption key, and an IC card 2.
The program that moves 00 is recorded. The card issuing machine 23 performs mutual authentication with the card using the temporary card issuing machine number, and then, as an initial value, the identification number of each terminal device (at this time, the true card issuing machine number is the temporary card issuing machine number). , The initial value of the game (for example, the number of balls held = 0) is written, and the card is issued.

Whether or not the card has not yet been issued is determined in step S18 whether the card has a temporary issuing machine number or not.
Alternatively, it is determined whether the true issuing machine number is included. If the temporary issuing machine number is included, the status is “before issuing”, and if the true issuing machine number is included, the status is “issued”. If the card has not been issued, the process proceeds to step S20, and "initial" is displayed on the LCD 212.
Is displayed. This state indicates that the card has been delivered from the card company 2. Therefore, this normally corresponds to a state where the tank of the card issuing machine 23 (where the cards are stocked) should be. However, when "initial" is displayed on the LCD 212, it is possible that the card has been stolen, for example, and "initial" is displayed so that the information on the card cannot be seen.

If the card has not been issued, step S2
Proceed to step 2 to determine whether the card has been updated.
If it has been updated, the process proceeds to step S24 and the LCD 21
"DEAD-CARD" is displayed in 2. This state is
It indicates that the card has been collected by the card renewal machine 24 after the expiration date has passed, and is disabled. Therefore, this normally corresponds to a state where the card should be in the recovery tank of the card updating machine 24. But,
When "DEAD-CARD" is displayed on the LCD 212, it is possible that the card was stolen from the collection tank, for example, and "DEAD-CARD" is displayed to disable the card.

If the card has not been issued and has not yet been updated, the process proceeds to step S26 to determine whether the card has been issued. If not issued, step S12
Then, the above process is repeated. On the other hand, if it has been issued, the process proceeds to step S28 and it is determined whether or not the operation rotation counter has a predetermined value. The operation rotation counter stores game-related information (that is, ball lending information, number-of-balls-information, accumulated-ball information, date of use, card status, today's balance, store number, store name, unit number) in the EEPROM 216. , If the same place (area) is continuously used, the durability of the storage area deteriorates, so each time it is used (for example, used for writing), information is written to the next area (of course, reading of information is also possible. Therefore, if all the ranges of the plurality of storage areas are used, it is counted up and used. Then, when one range is used, the storage area is rotated in order to use the same range again. Therefore, the operation rotation counter counts the number of times the storage area is rotated. This is because there is a guaranteed number of times of writing, and thus the method of rotating the storage area is adopted. Therefore, when the number of guarantees is reached, a new IC card is updated and a notification is given so that the operation of the IC card 200 can be guaranteed.

If the operation rotation counter is a predetermined value as a result of the determination in step S28, the process proceeds to step S30 and the message "Please update the card" is displayed on the LCD 212. This state is performed even if the expiration date has not passed. This allows the player to know that it is required to insert the card into the card updating machine 24 and update it. Then, step S
At 32, it is determined whether the key switch 217 of the card is turned on. If the key switch 217 is not turned on, the process returns to step S30 to repeat the process. When the key switch 217 is turned on, the process proceeds to step S34. If the operation rotation counter is less than the predetermined value as a result of the determination in step S28, the process skips steps S30 and S32 and proceeds to step S34.

In step S34, the display address pointer is acquired. Display address pointer, ball lending information (display), number of balls held information (display), accumulated ball information (display), today's balance (display), unit number (display), store name (display), expiration date (display) information Is a pointer for designating the storage address of the. Therefore, the value of the latest display address pointer for displaying each information is acquired, and the content of the address is read in step S36. That is, the display information stored at the address designated by the display address pointer is read.

First, in step S38, the ball lending amount (card balance) is displayed on the LCD 212. As a result, the player can know the remaining amount of money that can be used for the game while carrying the card. Next, in step S40, it is determined whether or not the key switch 217 has been pressed (ON). If not pressed, the process returns to step S38 to continue displaying the ball lending amount, and when the key switch 217 is pressed, In step S42, the accumulated amount of coins is displayed on the LCD 212. As a result, the player can know the amount of coins that can be used for the game while carrying the card. Similarly, in step S44, it is determined whether or not the key switch 217 is pressed, and if not pressed, the process returns to step S42 to continue displaying the accumulated amount of coins, and when the key switch 217 is pressed,
In step S46, the number of balls owned is displayed on the LCD 212.
As a result, the player can know the number of balls that can be used in the game while carrying the card.

Next, in step S48, the key switch 2
It is determined whether or not 17 is pressed, and if not pressed, the process returns to step S46 to continue displaying the number of balls, and when the key switch 217 is pressed, the expiration date of the card (expiration date of the card is determined in step S50). Is displayed on the LCD 212. As a result, the player can know the expiration date of the card while carrying the card. Next, in step S52, the key switch 21
It is determined whether or not 7 is pressed. If not pressed, the process returns to step S50 to continue displaying the expiration date, and when the key switch 217 is pressed, the today's balance (that is, the game result of today is determined in step S54). Corresponding income and expenditure situation) L
Display on CD212. As a result, the player can know the balance of today's game while carrying the card.

Next, in step S56, the key switch 2
It is determined whether or not 17 is pressed, and if not pressed, the process returns to step S54 to continue the display of today's balance, and when the key switch 217 is pressed, the hole name (that is, the last game is played) in step S58. Playing shop name) LCD21
Display on 2. As a result, the player can know the name of the game store while carrying the card. Next, in step S60, it is determined whether or not the key switch 217 is pressed. If not pressed, the process returns to step S54 to continue displaying the hole name, and when the key switch 217 is pressed,
In step S62, the unit number (that is, the unit number of the gaming machine that last played) is displayed on the LCD 212. As a result, the player can know the machine number of the gaming machine that last played the game while carrying the card.

Next, in step S62, the key switch 2
It is determined whether or not 17 is pressed, and if not pressed, the process returns to step S62 to continue displaying the machine number of the gaming machine,
When the key switch 217 is pressed, the processing returns to step S28 and is repeated. In this way, the key switch 217
Every time is pressed, the display content changes and the information is displayed, and the display information stored at the address is read out and L
It is displayed on the CD 212. As a result, the player can easily know the history of the game by displaying at least the desired information.

(B) In the case of the online mode (when inserted in the card reader / writer) This corresponds to the case where there is a power supply signal, and step S
If the determination result in 10 is NO, the process branches to step S66, and in the subsequent steps, a process of transferring information with the terminal device is executed. At this time, the frequency of the clock supplied to the CPU 213 becomes faster, and the clock extracting circuit 20
Clock signal from 2 (with fast clock frequency)
Is supplied to the CPU 213. In step S66, it is determined whether or not there is an activation command, and if there is no activation command, the process waits in this step, and if there is an activation command, step S68.
Activate with. In the activation process, a line test with the card reader / writer is performed, and idling is performed so that information can be smoothly transmitted between the card and the card reader / writer. Next, in step S70, it is determined whether or not there is any abnormality in the activation process. If an abnormality is confirmed, the process branches to step S72 to transmit the line abnormality to the card reader / writer, and the process returns to step S70.

When the line abnormality is eliminated, the process proceeds to step S74, and it is determined whether or not the temporary counter is equal to or more than a predetermined value (here, "5"). When the temporary counter is "5" or more, the process proceeds to step S76, and a card improper error command is transmitted to the card reader / writer. As a result, the card reader / writer recognizes that the card cannot be operated and disables the operation of the card. After step S76, step S7
Return to 0. Therefore, if the temporary counter is “5” or more, the process does not proceed to step S78 and subsequent steps, and the card information is not transferred with the terminal device.

When the temporary counter is less than "5", the process proceeds to step S78, the card issuing machine flag, the large amount of money addition machine flag, the gaming machine flag, the view POS flag,
Clear the update machine flag and the card company flag. Next, in step S80, card issuing machine processing is performed. This is a process for issuing a card at the request of the player when the terminal device is the card issuing machine 23 (details will be described later in a subroutine). Hereinafter, similarly, processing corresponding to each terminal device is performed. That is, in step S82, a large amount of money addition machine processing is performed, in step S84 game machine processing is performed, in step S86 scenic POS processing is performed, in step S88 update machine processing is performed, and in step S90, card company processing (details are The subroutine will be described later). These steps S82 to S8
Since the outline of the processing of 8 is the same as the card issuing machine processing in step S80, the card issuing machine processing will be described in detail as a representative. After step S90, the process returns to step S70 to repeat the process.

B. Subroutine of Card Issuer Processing FIG. 14 is a flowchart showing a subroutine of card issuer processing. When this subroutine starts,
In step S100, it is determined whether or not there is a check command from the card issuing machine 23. If the check command is not transmitted, the process branches to step S102 to determine whether or not there is a card issuing machine flag. If there is a card issuing machine flag, the process returns to step S100 to repeat the process,
If there is no card issuing machine flag, this routine is terminated and the process returns to the main program. On the other hand, if the check command is transmitted from the card issuing machine 23, the process proceeds to step S104 to set the card issuing machine flag. Next, in step S106, the temporary card issuer number received from the card issuer 23 (the identification number of that terminal device if it is another terminal device) and the temporary card issuer number stored in the card are used as the encryption key. Decrypt with a predetermined algorithm using and compare. The predetermined algorithm is, for example, an algorithm for exclusive-ORing the information stored in the scramble key area and the encrypted temporary card issuing machine number received from the card issuing machine 23 for decryption. Is.

Here, the game-related information in the card is encrypted and stored, and when transmitting information from the card (for example, transmitting to the terminal device), the information stored in the card is transmitted as it is. To do. That is, the encrypted information is transmitted to the terminal device. Therefore, the raw information is not stored in the card and the raw information is not encrypted at the time of transmission. Further, when receiving information from the terminal device, the received encrypted information is temporarily stored in a memory (for example, the RAM 215 used as a work area), and then the encrypted received information is stored. If the information is decrypted and the restriction items of the information are checked, if it is OK, the encrypted information stored in the memory is written in the addressing area of the EEPROM 216 according to the command. The command itself is not encrypted. Only the information that accompanies the command is encrypted. For example, if the "write command", "write area", and "information (encrypted information)" are sent from the terminal device to the card, the "write command" and "write area" are not encrypted. , "Information" only is encrypted. On the other hand, in the case of the “read command” for reading the information in the card, the encrypted and stored information is transmitted as it is (as the encrypted information) to the terminal device.

In step S108, the temporary card issuing machine number (if it is another terminal device, the identification number of that terminal device)
And a temporary card issuer number stored in the card is decrypted by a predetermined algorithm using an encryption key and compared, and it is determined whether or not the result is normal. If the comparison result is abnormal, the process branches to step S110 and the temporary counter is incremented by "1" and then step S10.
Return to 0. Therefore, at this time, the card becomes unresponsive. This is because the information for falsification is not shown by making no response so that the error code is not known. In addition,
The terminal device performs error handling (for example, ejects the card).

On the other hand, when the comparison result in step S108 is normal, it means that the card has recognized the mounted terminal device (that is, the card issuing machine 23). Next, in step S112, it is determined whether or not the temporary counter is "5" or more. If it is "5" or more, step S112 is performed.
At 114, a card failure error command is transmitted to the card reader / writer of the terminal device. At this time, the terminal device recognizes that the card cannot be operated, while the card itself disables the operation. After step S114, the process returns to step S100. Therefore, if the temporary counter is "5" or more, the process does not proceed to step S116 and subsequent steps, and the card information is not transferred with the card issuing machine 23.

If the temporary counter is less than "5", the flow advances to step S116 to determine whether the command is an undefined command. The undefined command is a command that is not defined between the card and the terminal device, and if there is an undefined command, an error, falsification, failure of the card, etc. are considered. Therefore, if there is an undefined command in step S116, the process returns to step S100. At this time, the card becomes unresponsive. This is because the information for falsification is not shown by making no response so that the error code is not known. Note that the terminal device performs error processing (for example, ejects the card).

If there is no undefined command in step S116, the flow advances to step S118 to determine whether or not there is a security request command (transmitted) from the card reader / writer of the card issuing machine 23. If there is a security request command, the process branches to step S120 to transmit the security check command, the stored security code (encrypted) and the card number (serial number) to the card reader / writer of the terminal device. As a result, the terminal device checks the security code and recognizes the card. After step S120, the process returns to step S100 to repeat the loop. In this way, mutual authentication is performed between the card and the terminal device (card issuing machine 23).

The above mutual authentication process will be described with reference to FIG. 19. The terminal device (that is, the card issuing machine 23)
Sends a terminal check command, a terminal device identification number (encrypted information), and a security data request command to the card (that is, the IC card 200). In this case, the terminal device identification number is individual identification information, for example, a temporary card issuing machine identification number. Further, the terminal check command and the security data request command are merely command commands and are not encrypted. The card receives the terminal check command transmitted from the terminal device, and performs processing for checking the terminal device based on the received terminal check command. That is, the card obtains the terminal device identification number by decrypting the information (encrypted terminal device identification number) based on the terminal check command received from the terminal device with a predetermined algorithm using an encryption key.

Next, the decrypted terminal device identification number (hereinafter referred to as the decrypted terminal device identification number transmitted from the terminal device) and the decrypted terminal device identification number stored in advance in the card are shown. Check by comparing and collating, but at this time, the terminal device identification number stored beforehand in the card is encrypted, so before checking, the terminal device identification number stored beforehand in the card is encrypted. The key is used to decrypt with a predetermined algorithm, and the decrypted terminal device identification number (hereinafter referred to as the terminal device identification number held in the card) is acquired. Then, the terminal device identification number transmitted from the terminal device and decrypted and the decrypted terminal device identification number held in the card are compared and checked (the terminal device identification number confirmation processing is performed), and they match. If O
As K (judged to be a valid terminal device), a security check command based on the previously received security data request command, previously stored security data (encrypted information) and card number (encrypted) Information) to the terminal device.

The terminal device receives the security check command transmitted from the card, and on the basis of the received security check command, the security code (encrypted information) is decrypted with a predetermined algorithm using an encryption key for security. Get the code. Then
The decrypted security code and the security code stored in the terminal device are compared and collated and checked (card confirmation processing is performed), and if they match (if the security code is legal), OK (valid card) Mutual authentication is completed.

In step S122, it is determined whether or not there is a read command, and if there is a read command, step S122
It branches to 124 and determines whether or not there is reading of information to the non-access area. This is because the information that can be read is defined for each terminal device (see the access right situation in FIG. 10). (A) When reading information to the non-access area If the information is read to the non-access area, the process branches to step S126, the parameter error command is transmitted to the terminal device, and the process returns to step S100. Therefore, at this time, the card information cannot be read. After returning to step S100, the process is repeated. (B) In the case of reading information to an area (accessible area) that is not the non-access area If the information is not read to the non-access area in step S124, the flow advances to step S128 to specify the designated data (read request information). ) Is acquired from the memory of the current operation address pointer or the dedicated memory and set as transmission data.

Here, the memory of the operating address pointer corresponds to the area of each column of address 5 to address 154 in the memory map shown in FIG. 9, and is not stored in the memory of the operating address pointer. Has information on ball lending information, number of balls owned, stored ball information, date of use, card status, today's balance, store number, store name, and machine number. On the other hand, the dedicated memory means the address 0 in the memory map shown in FIG.
~ Corresponding to the area of each column of address 4, address 255, address 255 and stored in the dedicated memory, for example, the issuing machine number, the updating machine number, the large amount of money addition machine number, the gaming machine number, the prize POS number , Card number, security code, temporary counter, expiration date, etc. Next, in step S130, the security check command, the stored security code (encrypted) and the card number are transmitted to the terminal device. Next, in step S132, the read response command and the previously set transmission data are transmitted to the terminal device. At this time, since the transmission data is encrypted, it is transmitted as it is.

Here, even if the information is encrypted between the card and the terminal device, each time the information is transferred,
Mutual authentication is performed. For example, when an event occurs and information needs to be read from the card, mutual authentication processing is performed each time. This is shown in FIG.
20, a terminal check command, a terminal device identification number (encrypted information) from the terminal device (card issuing machine 23) to the card (that is, the IC card 200), as shown in FIG. A read command (a command requesting to read information) and a parameter (which specifies information of a read request) encrypted by a predetermined algorithm using an encryption key are transmitted. The terminal device identification number is individual identification information, for example, a card issuer identification number.

When the card receives the terminal check command transmitted from the terminal device, the card checks the terminal device based on the received terminal check command. That is, the card is information (encrypted terminal device identification number) based on the terminal check command received from the terminal device.
Is decrypted with a predetermined algorithm using an encryption key to obtain the terminal device identification number. The decrypted terminal device identification number (that is, the terminal device identification number transmitted from the terminal device and decrypted) and the decrypted terminal device identification number stored in the card in advance are compared and checked. However, at this time, since the terminal device identification number stored in the card in advance is encrypted, the terminal device identification number stored in advance in the card is determined using the encryption key before checking. The decrypted terminal device identification number (that is, the terminal device identification number held in the card) is obtained by decryption using the algorithm. Then, the terminal device identification number transmitted from the terminal device and decrypted and the decrypted terminal device identification number held in the card are compared and checked (the terminal device identification number confirmation processing is performed), and they match. If O
As K (judged to be a valid terminal device), a read response command based on the previously received read command, information (encrypted) corresponding to the parameter designating the read request information, and a security check command , A prestored security code ((encrypted information) and card number (encrypted information) is transmitted to the terminal device.

The terminal device receives the security check command transmitted from the card, and based on the received security check command, the security code (encrypted information) is decrypted by a predetermined algorithm using an encryption key to perform security. Get the code. Then
The decrypted security code and the security code stored in the terminal device are compared and collated and checked (card confirmation processing is performed), and if they match (if the security code is legal), OK (valid card) Mutual authentication is completed. The information received from the card is then similarly decrypted and used. In the decryption, a cryptographic key is used and processing is performed by a predetermined algorithm.
For example, the decryption is performed using an algorithm that performs an exclusive OR of the encryption key received and stored from the terminal device and the encrypted information received from the card to perform decryption.

Thus, even if the information is encrypted between the card and the terminal device (here, the card issuing machine 23), mutual authentication is performed every time the information is transferred, and the mutual authentication result is obtained. After confirming that the card is OK (the card and the terminal device are valid), the data on the card is used.
Therefore, for example, when an event occurs, the card issuing machine 2
When it is necessary to read the information from 3, the mutual authentication process is performed each time, and the security of the card information is further enhanced. Note that when an event occurs and information is written to the card, mutual authentication is similarly performed, and after confirming that the mutual authentication result is OK (the card and the terminal device are valid), the data is written to the card. After step S132, the process returns to step S100 to repeat the process.

If the command is not a read command in step S122, the flow advances to step S134 to determine whether the command is a write command. If it is not a write command, the process returns to step S116 to repeat the loop. If it is a write command, it is determined in step S136 whether or not information has been written in the non-access area. This is because the information that can be written on the card is defined for each terminal device (see the access right situation in FIG. 10). (C) In the case of writing information in the non-access area When writing information in the non-access area, the process branches to step S126, the parameter error command is transmitted to the terminal device, and the process returns to step S100. Therefore, at this time, the information cannot be written in the card, and the process returns to step S100 to repeat the process.

(D) In the case of writing information to the area (accessible area) which is not the non-access area If the information is not written to the non-access area in step S136, the process proceeds to step S138 to write in the dedicated data area. Or not. (D-1) If writing is not in the dedicated data area (writing outside the dedicated data area) If writing is not in the dedicated data area, step S1
Go to 40 and store the received data (encryption) in the memory,
In step S142, the received data is decrypted with a predetermined algorithm using the encryption key. For example, the information stored in the area of the scramble key and the encrypted received data are exclusive-ORed and decrypted using an algorithm.

Then, steps S144 to S1.
At 48, each restriction information is checked. That is, in step S144, it is determined whether or not the ball lending amount exceeds the maximum value (for example, 20,000 yen), and in step S146, it is determined whether or not the accumulated ball amount exceeds the maximum value (for example, 20,000 yen). In step S148, it is determined whether or not the number of balls held exceeds the maximum value (for example, 99999). If the determination result of any of the restriction information is NG, step S
After branching to 126, the parameter error command is transmitted to the terminal device, and the process returns to step S100. Therefore, at this time, the received data cannot be written to the card, and the process returns to step S100 to repeat the process.

If the determination result of all the restriction information is OK, the process proceeds to step S150 and the current working address pointer is incremented by "1". This is because the received data is newly written this time, and therefore the data writing area is advanced. Then, step S1
At 52, it is determined whether or not the operating address pointer exceeds a predetermined value (for example, the maximum value of the storage area of the address information). If the working address pointer does not exceed the predetermined value, the process jumps to step S158. On the other hand, if the working address pointer exceeds the predetermined value, the process advances to step S154 to set the working address pointer to the initial address pointer. This is because the maximum value of the storage area of the address information is exceeded, and the storage area is returned to the first storage area again. Next, in step S156, the operation rotation counter is incremented by "1". The operation rotation counter is incremented each time the operation address pointer makes a round in the range from the address 5 to the address 154. Information on the number of balls held, the amount of balls accumulated, the date of use, the card status, the current balance, the store number, the store name, and the machine number are stored in the area of address 5.

Then, the process proceeds to step S158, in which the encrypted information stored in the memory (step S158).
(See 140) is written in the area designated by the updated working address pointer. Next, step S16
At 0, it is determined whether the verification is normal. This is to confirm whether or not the information written in step S158 has been written normally (verify check). If the verification is abnormal, step S162
And the temporary counter is incremented by "1", and it is determined in step S164 whether the temporary counter is "3" or more. If the temporary counter is less than “3”, the process returns to step S158 and the same loop is repeated. As a result, the writing of information is tried again. Then, if the information is normally written, the process proceeds to step S166.

However, if the information is not normally written even after the writing of the information is repeated a plurality of times, that is, if the temporary counter becomes "3" or more in step S164, the process proceeds to step S165 and the writing error command is issued to the terminal device. , And returns to step S100. As a result, the terminal device recognizes that the card cannot operate, while the card itself disables the operation. Then, it returns to step S100. Therefore, step S
Although the processing from 100 is repeated, if the temporary counter reaches "5" or more after writing is tried several times, the process branches to YES in step S112, and the card transmission error command is transmitted to the terminal device. Then, the terminal device recognizes that the card cannot be operated, while the card itself disables the operation.

When the information is normally written, the process proceeds to step S166, and the security check command, the stored security code (encrypted) and the card number are transmitted to the terminal device (card issuing machine 23). Then, in step S168, the write response is transmitted to the terminal device. In this way, mutual authentication is performed each time information is transferred between the card and the terminal device. That is, in this case, when the verify check is normal when the information is written in the card, the mutual authentication process is performed and the write response (which informs the normal writing end) is transmitted to the terminal device. Next, in step S170, display calculation processing is performed. This is to convert the contents (hexadecimal data) of the memory of the latest operation address pointer into display data (decimal data or character data) (details will be described later in a subroutine). After step S170, the process returns to step S100 to repeat the process.

(D-2) Writing to the dedicated data area If the writing is to the dedicated data area in step S138, the process branches to step S172 to write the received data in the memory of the designated dedicated address. What can be written in the dedicated data area (that is, stored in the dedicated memory) is, for example, the issuing machine number, the updating machine number, the large amount of money addition machine number, the gaming machine number, the prize POS number, the card number, the security code, the temporary. There is information such as counters and expiration dates. Next, in step S174, it is determined whether the verification is normal. This is step S
A write check (verify check) is performed to confirm whether the information written in 172 is normally written.

If the verify is abnormal, step S1
The process branches to 76 to increment the temporary counter by "1", and in step S178 it is determined whether the temporary counter is "3" or more. If the temporary counter is less than "3", the process returns to step S172 to repeat the same loop. As a result, the writing of information is tried again. If the information is written normally, the verification becomes normal and step S1
Go to 82. However, if the information is not normally written even if the writing of the information is repeated a plurality of times, that is, if the temporary counter becomes “3” or more in step S178, the process proceeds to step S180, and the writing error command is transmitted to the terminal device. , And returns to step S100. As a result, the terminal device recognizes that the card cannot operate, while the card itself disables the operation.

If the information is normally written, the verification becomes normal and the process proceeds to step S182, and the security check command, the stored security code (encrypted) and the card number are input to the terminal device (card issuing machine). 23). Next, step S18
At 4, the write response is transmitted to the terminal device. Thus, even when writing to the dedicated data area between the card and the terminal device, each time the information is transferred,
Mutual authentication is performed. That is, in this case, when the information is written in the dedicated data area of the card, if the verify check is normal, the mutual authentication process is performed and the write response (which informs the normal writing end) is transmitted to the terminal device. After step S184, the process returns to step S100 to repeat the process.

C. Display Calculation Subroutine FIG. 17 is a flowchart showing a display calculation subroutine in the card issuing machine process. When this subroutine starts, the display address pointer is incremented by "1" in step S200. This is because, since the received data is newly written this time, the display data area for displaying the data is advanced to the next. In addition, the display address pointer is for ball lending information (display), number of balls owned information (display), accumulated ball information (display), today's balance (display), unit number (display), store name (display), expiration date (display) The address for storing each piece of information is designated, and is incremented each time an access is made in the range from address 156 to address 252 to designate the next address. Next, in step S202, it is determined whether or not the display address pointer exceeds a predetermined value (for example, the maximum value of the storage area of the address information). If the display address pointer does not exceed the predetermined value, step S
Jump to 206.

On the other hand, if the display address pointer exceeds the predetermined value, the flow advances to step S204 to set the display address pointer to the initial address pointer. This is because the maximum value of the storage area of the address information is exceeded, and the storage area is returned to the first storage area again. Next, in step S206, the contents of the current working address pointer are read. That is, the information in the area designated by the current operation address pointer (ball lending information, number of balls owned information, accumulated ball information, date of use, card status, today's balance, store number, store name, unit number) Read out. Next, in step S208, the encryption key is used to decrypt the memory contents (information) and the expiration date data in the area designated by the operation address pointer. At this time, the memory contents (information) and the expiration date data are hexadecimal data, and the hexadecimal data is decrypted as it is. In the decryption, for example, the information stored in the scramble key area is decrypted using an algorithm such that an exclusive OR of the encrypted data and the decrypted information is used.

Next, each data (hexadecimal data) decoded in step S210 is converted into decimal number data or character data. Then, in step S212, 10
The data converted into a base number or character data is written in the memory designated by the updated display address pointer. After step S212, the process returns to the card issuing machine process. As described above, when power is supplied from the terminal device (card issuing machine 23) to the IC card 200, the calculation for display is performed (that is, hexadecimal data is 10
It is performed that the data is converted into base data or character data and stored in a memory (storage area) for display data. This is because sufficient power cannot be obtained during operation by the solar cell 209, so the clock is lowered to reduce power consumption, and therefore sufficient power is supplied so that the display can be switched quickly when the display information is switched. It is calculated and recorded when there is supply and the operation clock is fast.

Therefore, when carrying (when the solar cell 209 is being driven), the information stored in the display data memory is searched, and the display information stored at the address is read and displayed on the LCD 212. At this time, the search information has already been converted into decimal data or character data, and it is sufficient to simply read it from the memory.
It is possible to quickly display necessary data while suppressing the power consumption of the card 200.

D. Subroutine of Card Company Processing FIG. 18 is a flowchart showing a subroutine of card company processing. Although this subroutine is similar to the card issuing machine process in terms of content, since it is used by the card company 2, it restricts writing to and reading from the memory area of the card (excluding password prohibition information). There is also no mutual authentication. When this subroutine starts, it is determined in step S300 whether there is a password check command. The password is stored in advance in the program in the ROM 214 of the IC card 200, and is stored in the program at the time of delivery from the card company 2, for example. The password check command is transmitted to the card from the terminal device of the card company 2. If the password check command has not been transmitted, the process branches to step S302 to determine whether or not there is a card company flag. If there is a card company flag, the process returns to step S300 to repeat the process. If there is no card company flag, this routine is ended and the process returns to the main program.

On the other hand, if the password check command is transmitted from the terminal device of the card company 23, the process proceeds to step S304, and it is determined whether or not there is password prohibition information in the memory of the dedicated address. The password prohibition information is information that prohibits the acceptance of the password, and is written on the card when the card company 2 issues the card. For example, the password prohibition information is written after writing predetermined initial information on the card. If there is password prohibition information, the process returns to step S300 to repeat the process. Therefore, at this time, even the card company 2 cannot access the IC card 200 at all even if the password is entered thereafter, and the security is improved.

If there is no password prohibition information, step S
Proceed to 306 to set the card company flag. Next, in step S308, the password received from the card is checked, and in step S310, it is determined whether or not the password check result is normal. If the password check result is abnormal, the process proceeds to step S312, the password prohibition information is written in the memory of the dedicated address in the card, and the process returns to step S330. As a result, even if the card company 2 inputs the password thereafter, the IC
The card 200 cannot be accessed, and security is enhanced. The case where the password check result is abnormal is, for example, a case where the card is stolen (theft at the manufacturing stage) before it is delivered from the card company 2 to the hall. At this time, since the password is not stored in the program of the ROM 214, it is found by the password check.

If the password check in step S310 is normal, the process proceeds to step S314 to determine whether or not there is a read command. If there is a read command, the process branches to step S316 and the designated data (read request information ) Is acquired from the memory and set as transmission data. In addition, when accessing from the card company 2, as can be seen from the access right situation of FIG. 10, all information other than the password prohibition information can be read, and there is no non-access area. Also, mutual authentication is not performed. Next, in step S318, the read response command and the previously set transmission data are transmitted to the terminal device (card company 2). At this time, since the transmission data is encrypted, it is transmitted as it is. After step S318, the process returns to step S300 to repeat the process.

If there is no read command in step S314, the flow advances to step S320 to determine whether there is a password prohibit command. If there is a password prohibition command, the process branches to step S312, the password prohibition information is written in the memory of the dedicated address in the same manner as above, and the process returns to step S300. Therefore, even if the card company 2 inputs the password, the IC card 200 cannot be accessed. On the other hand, if there is no password prohibit command, the process advances to step S322 to determine whether or not there is a write command. If there is no write command, the process returns to step S314 and repeats. If there is a write command, the process proceeds to step S324 and the received data is written in the specified memory. In the case of the card company 2, there is no distinction as a dedicated data area, and data can be written anywhere.

Here, when the card is delivered from the card company 2 to the hole, predetermined initial information is written in the card (written in the EEPROM 216). As the initial information, for example, an encrypted security code,
There is an encrypted card number, an encrypted temporary card issuer number, and an encryption key. In this case, the encryption of the security code and the card number and the encryption of the temporary card issuing machine number may be encrypted with different encryption keys. In this way, if the encryption of the security code and card number is made different from the encryption of the temporary card issuing machine number,
It is possible to further enhance the security by making the encryption keys of both parties separate.

Then, in step S326, a write check (verify check) is performed to confirm whether the verification is normal, that is, whether the information written in step S324 is normally written. If the verification is abnormal, the process branches to step S328, the write error command is transmitted to the terminal device (card company 2), and the process returns to step S300.
As a result, the terminal device recognizes that the data writing operation is impossible. However, in the case of the card company 2, writing of data can be tried any number of times.

When the received data is normally written, the verification becomes normal, the process proceeds to step S330, the write response is transmitted to the terminal device, and the process returns to step S300 to repeat the process. At this time, for example, when the above-described predetermined initial information is written to the card and the verify check is completed, the password prohibit command is transmitted, the determination result of step S320 is YES, and the process proceeds to step S312. Password prohibition information is written. As a result, even if the card company 2 inputs a password thereafter, the IC card 200 cannot be accessed and security is improved.

As described above, in this embodiment, the EEP of the card is
Game-related information stored in the ROM 216 (for example,
The ball lending information, the number of balls owned, the amount of accumulated balls, the date of use, the card status, the current balance, the store number, the store name, and the machine number) can be displayed on the LCD 212 by operating the key switch 217. . Therefore, it is possible to easily confirm desired game-related information before the player plays the game (while carrying the game). Compared to prepaid cards, it is extremely easy to see game-related information.
Further, when compared with the conventional IC card, the balance and the number of coins can be displayed only in the past, but in the present embodiment, such limited information (the number of coins and balance) is not displayed, and many This is extremely convenient because the game-related information can be distinguished and displayed easily.

Based on an external command (for example, a write command and write information from a mounted terminal device, a read command and information to be read), the command is analyzed in the card and the information in the card is sent to the outside. Since information is written on the card, it is extremely difficult to falsify the information in the card. That is, the memory (EEPROM 216) storing information cannot be directly accessed from the outside, and writing / reading to / from the memory cannot be performed unless the command and the communication procedure are known. Therefore, the security of the card can be improved. Moreover, no matter what method is used to tamper with the information in the card, if the command and communication procedure are unknown, writing / reading to / from the memory is extremely difficult (actually impossible), and Since high-level security processing such as checking access rights and restriction information is performed, it is not possible to easily tamper with the memory information, and damage can be minimized.

It is judged whether or not the information is normally written (that is, the information received from the terminal device (information to be written) is compared with the information actually written in the card). Therefore, accurate information can be written on the card, and the reliability of the card information can be improved without causing inconvenience (inconvenience) to the player or the game shop. Especially for cards used for games, valuable value (ball lending information), game value (ball number information,
Accurate information is written because the amount of accumulated coins) increases and decreases frequently (for example, in the case of the enclosed ball type gaming machine 31 of the present embodiment, the amount of money is added to the card and the increase or decrease in the number of possessed balls is recorded). However, in the present embodiment, such a request can be surely met. Since the limit value (maximum value) of the information (ball lending information, number-of-balls-holding information, ball-saving information) to be written on the card is regulated and judged, the safety of the card can be improved. That is, it is not possible to record a high value on the card that exceeds the limit value, so that the player can carry the card with confidence. Also, in a device that writes a valuable value (ball lending information) to a card (for example, a large amount of money adding machine 25), the valuable value information is broken due to an error or the like (for example, it becomes expensive valuable value information).
Even in this case, damage to the amusement store can be minimized.

By providing an access right to the information in the card for each terminal device (distinguishing between information that can be accessed (written / read) by the terminal device and information that cannot be accessed by the terminal device), the information can be handled accurately and safety can be ensured. You can improve your sex. Also, the information is not destroyed. Further, even if the command and communication procedure are known, if the procedure information of the terminal device that writes (adds) a valuable value (amount of money) to the card is not known, the amount of money is written in or read from each area of the memory. It can not be done and damage can be minimized.

Next, the present invention is shown in FIG.
9. The method is not limited to the method of encrypting the terminal device identification number, the security code and the like and storing them in the card as shown in FIG. For example, the present invention can be applied to a device in which raw data is stored in a card as it is without encrypting a terminal device identification number, a security code, etc., and the data is read to perform mutual authentication. In that case, the game-related information in the card is stored as raw data without being encrypted, and when transmitting information from the card (for example, to the terminal device), the information stored in the card remains unchanged. Send (However, mutual authentication processing is performed when transferring data)
Hereinafter, such an embodiment will be described with reference to FIGS. 21 and 22.

A. Procedure of Mutual Authentication between Card and Terminal Device Figure 21 shows the process of mutual authentication between card and terminal device.
The terminal check command, the terminal identification number, and the security data request command are transmitted from the terminal device (for example, the card issuing machine 23) to the card (that is, the IC card 200). In this case, the terminal device identification number is the individual identification information,
For example, the temporary card issuing machine identification number. The card performs a process of checking the terminal device based on the terminal check command transmitted from the terminal device. That is, when the card receives the terminal device identification number from the terminal device, the card compares and verifies with the terminal device identification number stored in advance in the card (performs the terminal device identification number confirmation process), and if they match. As OK (judged to be a valid terminal device), the security check command, the security data stored in advance, and the card number are transmitted to the terminal device based on the previously received security request command. Based on the security check command sent from the card, the terminal device compares and checks the received security data and the security data stored in the terminal device (performs card confirmation processing), and if they match ( If it is legitimate security data), the mutual authentication is completed as OK (judged to be a valid card).

B. 22. Procedure for Mutual Authentication Each Time Event Occurs Next, FIG. 22 is a diagram showing a procedure for mutual authentication each time transfer of unencrypted information is performed between a card and a terminal device. As shown in FIG. 22, for example,
Whenever an event occurs and information (non-encrypted information) needs to be read from the card, mutual authentication processing is performed each time. First, the card (that is, the IC card 20) is sent from the terminal device (for example, the card issuing machine 23).
0), a terminal check command, a terminal device identification number, an A read command (a command that requests the reading of certain information: A information, for example), and a parameter (which specifies the information of the read request). The terminal device identification number is individual identification information, for example, a card issuer identification number.

The card performs a process of checking the terminal device based on the terminal check command transmitted from the terminal device. That is, when the card receives the terminal device identification number from the terminal device, the card compares and verifies with the terminal device identification number stored in advance in the card (performs the terminal device identification number confirmation process), and if they match. As OK (judged to be a valid terminal device), a read response command based on the previously received A read command, information (encryption) corresponding to the parameter designating the read request information, a security check command, and previously stored The transmitted security code (security data) and card number are transmitted to the terminal device.

Based on the security check command transmitted from the card, the terminal device compares and checks the received security code and the security code stored in the terminal device (performs card confirmation processing), and the two match. If so (if it is a legitimate security code), mutual authentication is completed as OK (judged to be a valid card). The information received from the card is then used. In this way, mutual authentication is performed each time transfer of unencrypted information is performed between the card and the terminal device (for example, the card issuing machine 23), and the mutual authentication result is O.
After confirming K (the card and the terminal device are valid), the data in the card is used. Therefore, for example, when an event occurs and it is necessary to read the information from the card issuing machine 23, the mutual authentication process is performed each time, and the security of the card information is further enhanced.

When an event occurs and information is written to the card, mutual authentication is similarly performed, and after confirming that the mutual authentication result is OK (the card and the terminal device are valid), the data is written to the card. Write. Therefore, as shown in FIG. 21 and FIG. 22, the information such as the terminal device identification number and the security code is stored in the card as raw data without being encrypted, and the data is read for mutual authentication. However, it is possible to obtain the same effect as that of the above embodiment. Further, in this case, there is an advantage that the processing is easy and the raw data can be directly handled when writing / reading the information because the information is not encrypted.

The embodiment of the present invention is not limited to the above-mentioned embodiment, but various modifications as described below are possible. (A) It can be applied to pachislot machines. (B) The present invention is applicable not only to pachinko gaming machines but also to, for example, video game machines. That is, as long as a game is played using cards, it can be applied to other types of game machines.

According to the present invention, game-related information recording means for recording game-related information on a game information medium (for example, an IC card), information writing means for writing information, and information reading means for reading information. Since the information display means for displaying the predetermined information is provided, the following effects can be obtained. (1) Game-related information (for example, ball lending information, number-of-balls-holding information, accumulated-ball information, etc.) recorded in the game-related information recording means (for example, memory) of the game information medium (for example, IC card)
The date of use, card status, today's balance, store number, store name, machine number) can be displayed on the information display means (for example, LCD) for viewing. (2) Therefore, it is possible to easily confirm desired game-related information before the player plays the game (at the stage of carrying the game). In particular, compared to prepaid cards, game-related information can be viewed very easily. Further, when compared with the conventional IC card, the remaining money and the number of coins can be displayed in the related art, but in the present invention, such limited information (the number of coins and the coin remaining) is not displayed. This is extremely convenient because the game-related information can be distinguished and displayed easily.

(3) Based on an external command (for example, a write command and write information from a mounted terminal device, a read command and information to be read), the command is analyzed in the game information medium to be stored in the game information medium. Since the information is sent to the outside or the information is written in the game information medium, it is extremely difficult to falsify the information in the game information medium. That is, the game-related information recording means that stores information cannot be directly accessed from the outside, and unless the command and communication procedure are known, writing / reading to / from the game-related information recording means cannot be performed. Therefore,
The security of the game information medium can be improved. (4) Further, even if any method is attempted to falsify the information in the game information medium, if the command and the communication procedure are unknown, writing / reading to / from the game-related information recording means is extremely difficult (actually, It is impossible to tamper with the information in the game-related information recording means, and the damage is minimized. Can be suppressed.

(5) It is judged whether or not the information is normally written (that is, the information received from the terminal device (information to be written) is compared with the information actually written in the game information medium). Since it makes a judgment), accurate information can be written in the game information medium, and there is no inconvenience (inconvenience) to the player or the game store, and the reliability of the information in the game information medium is improved. be able to. In particular, in the game information medium used for the game, the valuable value (ball lending information) and the game value (ball number information, accumulated ball information) increase / decrease frequently (for example, in the case of an enclosed ball game machine, the game information medium). Since the amount of money is added to and the increase / decrease in the number of balls is recorded), accurate writing of information is required, but the present invention can surely meet such a request. (6) Since the limit value (maximum value) of the information (ball lending information, number-of-balls-holding information, and stored-ball information) to be written in the game information medium is regulated and judged, the safety of the game information medium can be improved. it can. That is, it is not possible to record an expensive value exceeding the limit value in the game information medium, so that the player can carry the game information medium with confidence. (7) Also, in a device (for example, an amount-adding machine) that writes a valuable value (ball lending information) in the game information medium, the valuable value information is broken due to an error or the like (for example, it becomes expensive valuable value information). Even in this case, damage to the amusement store can be minimized.

(8) Information is handled accurately by providing an access right to information in the game information medium for each terminal device (distinguishing between information that can be accessed (written / read) by the terminal device and information that cannot be accessed). It is possible to improve safety. Also, the information is not destroyed. (9) Further, even if the command and the communication procedure are known, if the procedure information of the terminal device that writes (adds) a valuable value (amount of money) to the game information medium is not known, the amount of money is recorded in each of the game-related information recording means. Write to the area,
It cannot be read out and damage can be minimized.
