The processing unit 104 associates the acquired information code information with the check-in information corresponding to the information code information, and stores the information in the storage unit 109. The conversion unit 103 acquires the information code information acquired by the processing unit 104. The conversion unit 103 acquires the server URL and the global ID included in the acquired information code information. The conversion unit 103 converts the acquired server URL and the global ID to create (generate) a QR code. Creation unit 106 acquires the QR code created by conversion unit 103. Creation unit 106 creates a print request including a request to print the acquired QR code and addressed to printer 300. Creation unit 106 transmits the created print request to first communication unit 102-1. The first communication unit 102-1 transmits the print request output by the creation unit 106 to the printer 300. The printer 300 prints a QR code label based on the print request transmitted by the order management device 100.

[0036] The processing unit 104 acquires the first order notification information received by the second communication unit 102-2. Based on the global ID included in the acquired first order notification information, the processing unit 104 registers the order information included in the first order notification information in the storage unit 109 in association with information code information including the global ID. The creation unit 106 acquires the first order notification information from the processing unit 104. The creation unit 106 acquires the global ID included in the first order notification information based on the acquired first order notification information. The creation unit 106 acquires the check-in information stored in association with the acquired global ID from the storage unit 109. The creation unit 106 creates a print request addressed to the printer 300, including a request to print an account slip and cooking instructions including item numbers for identifying each of one or more menus ordered at a table corresponding to the information identifying the table included in the acquired check-in information and information identifying the quantity of each of the one or more menus. The creation unit 106 transmits the created print request to the first communication unit 102-1.

[0037] The first communication unit 102-1 transmits the print request output by the creation unit 106 to the printer 300. The printer 300 prints the bill and cooking instructions based on the print request transmitted by the order management device 100. The cooking instructions are carried to the kitchen. The bill is carried to the customer's table when the food is served. Fig. 4 is a diagram showing an example of cooking instructions. The cooking instructions include information specifying the date and time when the cooking was instructed ("2010 / 07 / 08 08:45" in Fig. 4), information specifying the menu ("chicken gratin" in Fig. 4), information specifying the table where the order was placed ("16" in Fig. 4), the receipt identification number ("00555-1" in Fig. 4), and information specifying the person in charge of the table ("4" in Fig. 4). Fig. 5 is a diagram showing an example of an account slip. As shown in Fig. 5, the account slip includes check-in information (table number and information identifying the number of customers), date, time, information identifying the person in charge, information identifying one or more menu items included in the order information, information indicating the quantity of each of the one or more menu items, information indicating the price of each of the one or more menu items, and a total price. Returning to Fig. 2, the explanation will be continued.

[0038] The processing unit 104 detects that a failure has occurred in the network between the second communication unit 102-2 and the server device 400. For example, when the processing unit 104 transmits store check-in information, order information, or the like to the server device 400, or when the processing unit 104 periodically performs a connection monitoring process with the server device 400, if it recognizes that it is unable to access the server device 400 for a certain period of time, it determines that a failure has occurred. When the processing unit 104 detects that a failure has occurred in the network, the issuing unit 105 issues an alternative URL. The conversion unit 103 acquires the alternative URL issued by the issue unit 105. The conversion unit 103 acquires a global ID from each of one or more pieces of information code information stored in the storage unit 109. The conversion unit 103 acquires check-in information associated with each of one or more pieces of information code information stored in the storage unit 109. The conversion unit 103 converts the acquired alternative URL and global ID to create a QR code. With this configuration, at the time when the occurrence of a failure is detected, the order management device 100 can convert the alternative URL and global ID to create a QR code for all tables in the store RE that have unpaid orders.

[0039] Creation unit 106 acquires the QR code created by conversion unit 103. Creation unit 106 creates a print request addressed to printer 300, including a request to print the acquired QR code. Creation unit 106 outputs the created print request to first communication unit 102-1. The first communication unit 102-1 sends the printing request output by the creation unit 106 to the printing device 300. The printing device 300 prints the QR code label based on the printing request sent by the order management device 100. With this configuration, the printed QR code label can be redistributed to each table, so that for additional orders from the customer terminal 50 of the customer after redistribution, the customer can be prompted to register at an alternative customer ordering site accessed by an alternative URL. In this case, the global ID remains the same as it was before. Here, a service set ID (SSID) and a passcode for connecting to the wireless LAN of the store RE may be printed together with the QR code, or may be included in the QR code. The customer accesses the alternative customer ordering site by switching the connection of the customer terminal 50-1 to the wireless LAN of the store RE. It is preferable to update the service set ID and the passcode every day. This configuration ensures security. However, the employee terminal 30 connects to the order management device 100 with a service set ID different from the service set ID used by the customer. For this reason, the update cycle of the service set ID and the passcode used by the customer may be lengthened.

[0040] The processing unit 104 acquires the order information received by the first communication unit 102-1. Based on the global ID included in the acquired order information, the processing unit 104 registers the order information in the storage unit 109 in association with information code information including the global ID. The creation unit 106 acquires the order information from the processing unit 104. The creation unit 106 acquires the global ID included in the order information based on the acquired order information.

The creation unit 106 creates a print request addressed to the printing device 300, including a request to print an account slip and cooking instructions including item numbers for identifying each of one or more menus ordered at a table corresponding to the information identifying the table included in the acquired check-in information and information identifying the quantity of each of the one or more menus. The creation unit 106 outputs the created print request to the first communication unit 102-1. The first communication unit 102-1 transmits the print request output by the creation unit 106 to the printer 300. The printer 300 prints an account slip and cooking instructions based on the print request transmitted by the order management device 100.

[0056] 10 is a flowchart showing a fifth example of the operation of the self-ordering system according to this embodiment. Following on from FIG. 9, the operation of the self-ordering system will be described with reference to FIG. (Step S1-5) In the order management device 100, the second communication unit 102-2 receives the recovery notification transmitted by the server device 400.

The processing unit 404 stores each of the one or more pieces of order information in the storage unit 409 in association with store check-in information that is stored in association with the same global ID as the global ID included in each of the one or more pieces of order information included in the second order notification information. Steps S5-5 to S17-5 are similar to steps S8-1 to S11-1 in FIG. 6 and steps S1-2 to S9-2 in FIG. 7, and therefore will not be described here.

[0057] In the above embodiment, the order management device 100-1 creates a QR code by converting a server URL and a global ID, but the present invention is not limited to this example. For example, the order management device 100-1 may create a QR code by converting a server URL, or may create a QR code by converting at least one of a store code and check-in information in addition to the server URL and the global ID. In the above-described embodiment, the alternative customer ordering site may be a site that is simpler than the customer ordering site. Specifically, the alternative customer ordering site may have no images and may display only text. By configuring it in this way, the load on the customer terminal 50 can be reduced, so that customers who use the customer terminal 50 to place orders do not feel stressed by operations, displays, etc. In the above-described embodiment, when the customer terminal 50 first accesses the server device 400, the server device 400 may notify the customer terminal 50 of an alternative URL. In this case, when the customer terminal 50 cannot access the server device 400, the customer terminal 50 may access the alternative URL. The customer terminal 50 may directly connect to the server device 400 via the antenna AN and the network NW-2, or may connect to the server device 400 via a network NW-1 such as a wireless LAN of the store RE and the network NW-2. When the customer terminal 50 connects to the server device 400 via the network NW-1 and the network NW-2, when communication with the server device 400 becomes impossible, the connection to the order management device 100 can be smoothly switched. In the above-described embodiment, a dual-redundant system may be constructed by integrating the wireless access point and the printer 300 and using two devices. With this configuration, even if one of the devices breaks down, either the order management function or the wireless communication function will still function, so system downtime can be avoided. This makes it possible to construct an ordering system that will not go down even when a problem occurs not only with the internet line but also with in-store devices.

[0058] According to the self-ordering system 1 of the present embodiment, the system includes an order management device 100 and a server device 400 that communicates with the order management device 100, and an order is placed by a customer terminal 50 used by the customer. The customer terminal 50 transmits order information related to the customer's order to the server device 400 when the order management device 100 can communicate with the server device 400, and transmits the order information to the order management device 100 when the order management device 100 cannot communicate with the server device 400. When the server device 400 receives order information from the customer terminal 50, the server device 400 stores the order information in itself and transmits first order notification information including the order information to the order management device 100, and when the order management device 100 receives order information from the customer terminal 50, the server device 400 stores the order information in itself and transmits second order notification information including the order information to the server device 400. The server device 400 receives the second order notification information from the order management device 100, acquires the order information included in the received second order notification information, and stores the order information. The order management device 100 receives the first order notification information from the server device 400, acquires the order information included in the received first order notification information, and stores the order information, thereby storing the same order information. With this configuration, order information can be managed doubly, since it can be stored in both the order management device 100 and the server device 400. Therefore, in a self-ordering system in which customers place orders using their own customer terminals, even if a network error occurs, the system will not go down and the order input and registration work can continue at the store.

[0059] In the above-mentioned self-ordering system 1, the order management device 100 includes a creation unit 106 that acquires check-in information, which is information for identifying a customer who has entered the store, from the employee terminal 30 used by an employee, and creates store check-in information including the acquired check-in information and store identification information of the store, and a conversion unit 103 that acquires customer identification information transmitted by the server device 400 and server device identification information, which is information for identifying the server device 400, from the store check-in information, and converts the customer identification information and the server device identification information into a first information code. The server device 400 includes an issuing unit 405 that issues customer identification information in response to the store check-in information transmitted by the order management device 100, a processing unit 404 that stores the order information transmitted by the customer terminal 50 using the server device identification information acquired by reading the first information code in a storage unit 409 of the server device 400 together with the customer identification information, and a creation unit 406 that creates first order notification information addressed to the order management device 100, based on the order information. The order management device 100 includes a processing unit 104 that acquires the first order notification information transmitted by the server device 400 and stores the acquired first order notification information in a storage unit 109 of the order management device 100. By configuring in this manner, the order management device 100 can obtain the customer identification information of the customer sent by the server device 400 and server device identification information, which is information that identifies the server device 400, in response to the store check-in information, and convert the customer identification information and the server device identification information into a first information code, so that when the order management device 100 can communicate with the server device 400, it can perform order input and registration operations at the store.

[0060] In the above-described self-ordering system 1, the order management device 100 includes an issuing unit 105 that issues alternative device identification information, which is information for identifying a device that substitutes for the server device 400, when communication with the server device 400 is not possible. After acquiring the customer identification information of the customer transmitted by the server device 400, the converting unit 103 of the order management device 100 converts the customer identification information and the alternative device identification information into a second information code when communication with the server device 400 is not possible. The processing unit 104 of the order management device 100 stores the order information transmitted by the customer terminal 50 using the alternative device identification information acquired by reading the second information code in the storage unit 109 of the order management device 100 together with the customer identification information. With this configuration, when the order management device 100 cannot communicate with the server device 400 after acquiring the customer identification information of the customer transmitted by the server device 400, the order management device 100 issues substitute device identification information, which is information for identifying a device that substitutes for the server device 400, and converts the customer identification information and the substitute device identification information into an information code. Therefore, the customer can continue to register the order with the previous order information by connecting the customer terminal 50 to a wireless LAN in the store RE and accessing the substitute URL read from the QR code. In addition, the customer can also register the order by conveying the order information to an employee without using the customer terminal 50. Therefore, even if an abnormality occurs in the network and the order management device 100 cannot communicate with the server device 400, the order input and registration work can be continued in the store without the system going down.

[0061] In the above-mentioned self-ordering system 1, when communication between the order management device 100 and the server device 400 is restored, the creation unit 106 of the order management device 100 creates second order notification information addressed to the server device 400, including the order information and customer identification information stored while the order management device 100 was unable to communicate with the server device 400, from the order information stored in the memory unit 109 of the order management device 100, and the processing unit 404 of the server device 400 stores the order information included in the second order notification information in the memory unit of the server device 400, based on the customer identification information included in the second order notification information sent by the order management device 100. With this configuration, when communication between the order management device 100 and the server device 400 is restored, it is possible to synchronize the order information stored in the order management device 100 with the order information stored in the server device 400. Therefore, the order information can be managed doubly by the order management device 100 and the server device 400.

[0062] In the above-mentioned self-ordering system 1, when the order management device 100 transmits second order notification information to the server device 400, the conversion unit 103 of the order management device 100 converts the customer identification information and the server device identifying information into a first information code, and the creation unit 406 of the server device 400 creates the first order notification information addressed to the order management device 100 based on the order information transmitted by the customer terminal using the server device identifying information obtained by reading the first information code. By configuring in this manner, when communication between the order management device 100 and the server device 400 is restored and the order management device 100 sends order notification information to the server device 400, the customer identification information and the server device specific information can be converted into the first information code, so that the processing can be returned to the case when the order management device 100 can communicate with the server device 400.

[0063] (Modification of the embodiment) A self-ordering system 1a according to a modification of the embodiment can be applied to Fig. 1. However, it differs in that it includes an order management device 100a-1 instead of the order management device 100-1, and an order management device 100a-2 instead of the order management device 100-2. A case will be described where the order management device 100a-1 attempts to transmit shop check-in information to the server device 400 but is unable to transmit due to a failure. The order management device 100a-1 issues information for identifying a customer in the store RE (hereinafter referred to as a “local ID”). The order management device 100a-1 issues an alternative URL of a device that serves as an alternative to the server device 400. The order management device 100a-1 associates the check-in information included in the store check-in information to be transmitted with the issued alternative URL and local ID, and stores them in the storage unit 109. The order management device 100a-1 creates a QR code by converting the alternative URL and the local ID. The order management device 100a-1 outputs a print request for the created QR code to the printer 300. The printer 300 acquires the print request output by the order management device 100a-1, and prints a QR code label based on the acquired print request.

[0064] A customer reads the QR code label printed by the printer 300 with the customer terminal 50-1. The customer terminal 50-1 acquires the alternative URL and local ID represented on the read QR code label. The customer terminal 50-1 accesses the order management device 100a-1 using the acquired alternative URL to access the customer ordering site. The customer refers to the menu included in the customer ordering site and places an order. The customer terminal 50-1 creates order information based on the customer's ordering operation. The order information includes the local ID, an item number for identifying each of the one or more menu items, and information specifying the quantity of each of the one or more menu items. The customer terminal 50-1 transmits the created order information to 100a-1. The order management device 100a-1 receives the order information transmitted by the customer terminal 50-1. The order management device 100a-1 identifies the check-in information stored in association with the local ID included in the received order information, and registers the order information in association with the identified check-in information. The order management device 100a-1 creates an account slip and cooking instructions based on the registered order information. The order management device 100a-1 outputs a print request for the created account slip and cooking instructions to the printer 300. The printer 300 acquires a print request for the bill slip and cooking instructions output by the order management device 100a-1, and prints the bill slip and cooking instructions based on the acquired print request for the bill slip and cooking instructions. When the failure is recovered, the server device 400 creates a recovery notification, which is information identifying that the failure has been recovered, and transmits the created recovery notification to the order management device 100a-1. The order management device 100a-1 receives the recovery notification transmitted by the server device 400, and detects that the network NW-2 has been restored based on the received recovery notification. The order management device 100a-1 creates one or more pieces of store check-in information including store identification information and check-in information based on one or more pieces of check-in information that could not be transmitted to the server device 400 due to the occurrence of the failure. The order management device 100a-1 transmits the created one or more pieces of store check-in information to the server device 400.

[0065] When the server device 400 receives one or more pieces of store check-in information transmitted by the order management device 100a-1, the server device 400 issues a global ID for each of the one or more pieces of store check-in information. The server device 400 registers the issued global ID and the store check-in information in association with each other. The server device 400 creates information code information that includes the global ID, the server URL, and the check-in information and is addressed to the order management device 100a-1. The server device 400 transmits the created information code information to the order management device 100a-1. The order management device 100a-1 receives the information code information transmitted by the server device 400. The order management device 100a-1 acquires the global ID, the server URL, and the check-in information included in the information code information. The order management device 100a-1 replaces the local ID and the alternative URL stored in the storage unit 109 in association with the acquired check-in information with the global ID and the server URL, respectively. The order management device 100a-1 creates a QR code by converting the replaced global ID and the server URL stored in association with the global ID. The order management device 100a-1 outputs a print request for the created QR code to the printer 300. The printer 300 acquires the printing request output by the order management device 100a-1, and reprints the QR code label based on the acquired printing request.

[0066] Among the employee terminal 30, customer terminal 50, order management device 100a, and server device 400 that are mainly included in the self-ordering system 1a according to the modified embodiment, the order management device 100a that differs from the embodiment will be described in detail below. FIG. 2 can be used to explain the employee terminal, customer terminal, order management device, and server device included in the self-ordering system 1a according to the modified embodiment. (Order management device 100a) The order management device 100a includes a first communication unit 102-1, a second communication unit 102-2, a conversion unit 103a, a processing unit 104a, an issuing unit 105a, a creation unit 106a, and a storage unit 109. The issuing unit 105a can be the same as the issuing unit 105. However, the issuing unit 105a differs in the following respects: When the processing unit 104 detects that a failure has occurred in the network, the issuing unit 105a issues a local ID and an alternative URL. Processing unit 104a can be applied to processing unit 104. However, processing unit 104a differs in the following respects. Processing unit 104a acquires the local ID and alternative URL issued by issuing unit 105a, associates the acquired local ID and alternative URL with the check-in information included in the shop check-in information to be transmitted, and stores them in storage unit 109. Conversion unit 103a can be the same as conversion unit 103. However, there are differences in the following points. Conversion unit 103a acquires the alternative URL and local ID issued by issue unit 105a. Conversion unit 103a acquires check-in information registered (stored) in association with the acquired alternative URL and local ID from storage unit 109. Conversion unit 103 creates (generates) a QR code by converting the store code, the acquired alternative URL, the local ID, and the check-in information.

[0067] The processing unit 104a acquires the order information received by the first communication unit 102-1. Based on the local ID included in the acquired order information, the processing unit 104a registers the order information in the storage unit 109 in association with the check-in information stored in association with the local ID. Creation unit 106a can be the same as creation unit 106. However, it differs in the following respects. When processing unit 104a detects that the failure has been restored, creation unit 106a creates one or more pieces of store check-in information including store identification information and check-in information based on one or more pieces of check-in information that could not be sent to server device 400 due to the occurrence of the failure. Creation unit 106a outputs the created one or more pieces of store check-in information to second communication unit 102-2. The processing unit 104a acquires the information code information received by the second communication unit 102-2. The processing unit 104a acquires the global ID, the server URL, and the check-in information included in the acquired information code information. The order management device 100a replaces the local ID and the alternative URL stored in the storage unit 109 in association with the acquired check-in information with the global ID and the server URL, respectively. The creation unit 106a creates a QR code by converting the store code, the replaced global ID, and the server URL. The creation unit 106a outputs a print request for the created QR code to the printer 300. All or some of the conversion unit 103a, the processing unit 104a, the issuing unit 105a, and the creation unit 106a are functional units (hereinafter referred to as software functional units) that are realized by, for example, a processor such as a CPU executing a program stored in the storage unit 109. Note that all or some of the conversion unit 103a, the processing unit 104a, the issuing unit 105a, and the creation unit 106a may be realized by hardware such as an LSI, an ASIC, or an FPGA, or may be realized by a combination of the software functional units and hardware.

(Step S4-7) In the order management device 100a, the creation unit 106a acquires order information from the processing unit 104a. The creation unit 106a acquires a local ID included in the order information based on the acquired order information. The creation unit 106a acquires check-in information stored in association with the acquired local ID from the storage unit 109. The creation unit 106a creates a print request addressed to the printing device 300, including a request to print an account slip and cooking instructions including item numbers for identifying each of one or more menu items ordered at a table corresponding to the information identifying the table included in the acquired check-in information, and information identifying the quantity of each of the one or more menu items. Steps S5-7 to S6-7 can be implemented by steps S8-2 to S9-2 in Fig. 7, so the explanation will be omitted here. Steps S7-7 to S9-7 can be implemented by steps S13-4 to S14-4 in Fig. 9 and step S1-5 in Fig. 10, so the explanation will be omitted here. (Step S10-7) In the order management device 100a, when the processing unit 104a detects that the failure has been recovered, the creation unit 106a creates one or more pieces of store check-in information including store identification information and check-in information based on one or more pieces of check-in information that could not be sent to the server device 400 due to the failure. Steps S11-7 to S14-7 can be implemented by steps S4-1 to S7-1 in FIG. 6, so a description thereof will be omitted here.

[0070] Fig. 13 is a flowchart showing a third example of the operation of the self-ordering system according to the modified example of the embodiment. Following on from Fig. 12, the operation of the self-ordering system according to the modified example of the embodiment will be described with reference to Fig. 13. (Step S1-8) In the order management device 100a, the processing unit 104a acquires the information code information received by the second communication unit 102-2. The processing unit 104a acquires the global ID, the server URL, and the check-in information included in the acquired information code information. The order management device 100a replaces the local ID and the alternative URL stored in the storage unit 109 in association with the acquired check-in information with the global ID and the server URL, respectively. (Step S2-8) In the order management device 100a, the creation unit 106a creates a QR code by converting the replaced global ID and the server URL. Steps S3-8 to S14-8 can be implemented by steps S9-1 to S11-1 in FIG. 6 and steps S1-2 to S9-2 in FIG. 7, so a description thereof will be omitted here.

[0071] According to a self-ordering system 1a relating to a modified embodiment, in the self-ordering system 1 relating to the above-described embodiment, when the order management device 100a is unable to communicate with the server device 400 before the order management device 100a acquires the customer identification information, the issuing unit 105a of the order management device 100a issues alternative customer identification information, which is alternative customer identification information, the converting unit 103a of the order management device 100a converts the alternative customer identification information and the alternative device identifying information into a second information code, the processing unit 104a of the order management device 100a acquires the order information transmitted by the customer terminal 50 using the alternative device identifying information acquired by reading the second information code, and stores the acquired order information in the memory unit 109 of the order management device 100. By configuring in this manner, if the order management device 100a is unable to communicate with the server device 400 before the order management device 100a acquires the customer identification information, the order management device 100a can issue alternative customer identification information, which is alternative customer identification information, and convert the alternative customer identification information and the alternative device identification information into other information codes. Therefore, even if a network abnormality occurs and the order management device 100 is unable to communicate with the server device 400, the system can continue to perform order input and registration operations at the store RE without going down.

[0072] In the above-mentioned self-ordering system 1a, the creation unit 106a of the order management device 100a acquires check-in information, which is information for identifying a customer who has entered the store, from the employee terminal 30 used by an employee, and when communication between the order management device 100a and the server device 400 is restored, creates store check-in information including the acquired check-in information and store identification information of the store, and the conversion unit 103a of the order management device 100a acquires, from the store check-in information, the customer identification information of the customer sent by the server device 400 and server device identification information, which is information for identifying the server device 400, and converts the customer identification information and the server device identification information into a second information code. By configuring in this manner, when communication between the order management device 100a and the server device 400 is restored, the order management device 100a creates store check-in information including check-in information and store identification information of the store, obtains the customer identification information and server device identification information of the customer sent by the server device 400 from the store check-in information, and converts the customer identification information and server device identification information into other information codes, so that when the order management device 100a can communicate with the server device 400, it is possible to perform order input and registration operations at the store.

[0073] In the above-mentioned self-ordering system 1a, the processing unit 104a of the order management device 100a associates the order information sent by the customer terminal 50 with the alternative customer identification information and stores them in the memory unit 109 of the order management device 100a, and when communication between the order management device 100a and the server device 400 is restored, changes the alternative customer identification information stored in the memory unit 109 of the order management device 100a to the customer identification information sent by the server device 400. By configuring in this manner, when communication between the order management device 100a and the server device 400 is restored, the alternative customer identification information stored in the memory unit 109 can be changed to the customer identification information sent by the server device 400, so that the customer's order information can be managed using the customer identification information.

[0074] The employee terminal 30, customer terminal 50, order management device 100, server device 400, and order management device 100a of the self-ordering system described above may be realized by a computer. In this case, a program for realizing the functions of each functional block is recorded on a computer-readable recording medium. The program recorded on this recording medium may be read into a computer system and executed by a CPU to realize the functions. The "computer system" referred to here includes the OS (Operating System) and hardware such as peripheral devices. In addition, "computer-readable recording media" refers to portable media such as flexible disks, optical magnetic disks, ROMs, CD-ROMs, etc. In addition, "computer-readable recording media" includes storage devices such as hard disks built into computer systems.

[0075] Furthermore, the term "computer-readable recording medium" may include a medium that dynamically holds a program for a short period of time. An example of a medium that dynamically holds a program for a short period of time is a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line. The term "computer-readable recording medium" may also include a medium that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or a client. The program may be a medium for realizing part of the above-mentioned functions. The program may be a medium that can realize the above-mentioned functions in combination with a program already recorded in the computer system. The program may be a medium that is realized by using a programmable logic device. The programmable logic device is, for example, an FPGA (Field Programmable Gate Array).

[0076] Furthermore, although each functional unit of the device described using the drawings is a software functional unit, some or all of the functions may be hardware functional units such as an LSI. The program may be for realizing part of the functions described above. Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program). Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
