　上記通信システム１において、ネットワーク通信インタフェースを持つスキャナ装置３は、ＰＣや携帯電話などのクライアント端末２からＴＣＰならびにＵＤＰのプロトコルデータを送受信して、スキャナ読み取りの一連の流れ（ユーザ操作、読み取り開始、データ転送、読み取り完了）を実行することができる。
　上記に加えて、新たなサービス（例えば、インスタントメッセンジャーサービス）との連携を実現しようとする場合、サービスが用意するフレームワーク（例えば、アプレットのフレームワーク）には、ＴＣＰならびにＵＤＰプロトコルによってデータを送受信するインタフェースが準備されていない場合もあり、リアルタイムに双方向通信可能なＷｅｂＳｏｃｋｅｔプロトコルを使った枠組みのみが提供される場合もある。そのため、実装済みのインタフェースをそのまま踏襲した形では機能を実現できない。通常は、ＷｅｂＳｏｃｋｅｔプロトコルによる新インタフェースを作成し、専用の読み取り機能を構築するのであろうが、品質確保などの技術的課題はもちろん、開発期間が長期に渡るなどビジネス的な側面でもリスクを 背負うといった課題がある。 In the communication system 1, the scanner device 3 having a network communication interface transmits and receives TCP and UDP protocol data from a client terminal 2 such as a PC or a mobile phone, and a series of scanner reading flows (user operation, reading start, Data transfer, read completion) can be executed.
In addition to the above, when trying to realize cooperation with a new service (for example, instant messenger service), data is sent and received to the framework provided by the service (for example, the framework of the applet) by TCP and UDP protocols. In some cases, the interface to be used is not prepared, and in some cases, only the framework using the WebSocket protocol capable of two-way communication in real time is provided. Therefore, the function cannot be realized by following the implemented interface as it is. Normally, a new interface using the WebSocket protocol will be created to build a dedicated reading function, but there are technical issues such as quality assurance, as well as risks in terms of business such as a long development period. There are challenges.
　そこで、本実施形態の通信システム１におけるスキャナ装置３のファームウェアでは、後述する中継部５２０（ＷｅｂＳｏｃｋｅｔサーバ機能）を実装して、ＷｅｂＳｏｃｋｅｔプロトコルをサポートし、このインタフェースから受信されたデータを、スキャナ装置３内部で独自にプロトコル変換し、実装済みのＴＣＰ／ＵＤＰインタフェースにバイパス送信する手法を考案した。スキャナ装置３から送信するデータも同様に、ＴＣＰ／ＵＤＰインタフェースによって、一旦、スキャナ装置３内部にローカルに送信後、 中継部５２０にバイパス送信し、クライアント端末６に転送する仕組みを実現した。 Therefore, in the firmware of the scanner device 3 in the communication system 1 of the present embodiment, a relay unit 520 (WebSocket server function) described later is implemented to support the WebSocket protocol, and the data received from this interface is used as the scanner device 3. We devised a method to convert the protocol internally and send it by bypass to the implemented TCP / UDP interface. Similarly, the data transmitted from the scanner device 3 is also transmitted locally inside the scanner device 3 by the TCP / UDP interface, then bypass-transmitted to the relay unit 520 and transferred to the client terminal 6.

　図３は、スキャナ装置３の機能構成を例示する図である。
　図３に例示するように、本例のスキャナ装置３には、スキャナプログラム５がファームウェアの一部としてインストールされ、動作する。スキャナプログラム５は、例えば、インターネット７を介して配布される。なお、スキャナプログラム５は、ＣＤ－ＲＯＭ等の記録媒体に格納されており、クライアント端末２を介して、スキャナ装置３にインストールされてもよい。
　スキャナプログラム５は、制御部５００、占有制御部５０２、スキャナ処理部５１０、第１通信部５１２、及び、中継部５２０を有する。
　なお、スキャナプログラム５の一部又は全部は、ＡＳＩＣなどのハードウェアにより実現されてもよく、また、ＯＳ（Ｏｐｅｒａｔｉｎｇ Ｓｙｓｔｅｍ）の機能を一部借用して実現されてもよい。 FIG. 3 is a diagram illustrating the functional configuration of the scanner device 3.
As illustrated in FIG. 3, the scanner program 5 is installed and operates as a part of the firmware in the scanner device 3 of this example. The scanner program 5 is distributed, for example, via the Internet 7. The scanner program 5 is stored in a recording medium such as a CD-ROM, and may be installed in the scanner device 3 via the client terminal 2.
The scanner program 5 includes a control unit 500, an occupation control unit 502, a scanner processing unit 510, a first communication unit 512, and a relay unit 520.
A part or all of the scanner program 5 may be realized by hardware such as an ASIC, or may be realized by borrowing a part of the functions of the OS (Operating System).
　スキャナプログラム５において、制御部５００は、スキャナプログラム５の各構成を制御する。例えば、制御部５００は、スキャナ装置３の仕向け先情報、及び、既定のサービスとの連携の有効又は無効、の少なくとも一方に応じて、中継部５２０の機能を起動又は停止させる。本例の制御部５００は、スキャナ装置３の仕向け先がＡ国であり、かつ、サービスＢとの連携機能が有効である場合に、中継部５２０を起動させ、スキャナ装置３の仕向け先がＡ国以外である場合、又は、サービスＢとの連携機能が無効に設定されている場合、中継部５２０を停止した状態にさせる。 In the scanner program 5, the control unit 500 controls each configuration of the scanner program 5. For example, the control unit 500 activates or stops the function of the relay unit 520 according to at least one of the destination information of the scanner device 3 and the enable / disable of the cooperation with the default service. The control unit 500 of this example activates the relay unit 520 when the destination of the scanner device 3 is country A and the cooperation function with the service B is effective, and the destination of the scanner device 3 is A. If it is outside the country, or if the function of linking with service B is disabled, the relay unit 520 is stopped.
　占有制御部５０２は、スキャナ処理部５１０によるスキャナ処理中に、第１通信部５１２及び中継部５２０における通信経路を占有状態に設定する。本例では、中継部５２０を経由する通信経路（ＷｅｂＳｏｃｋｅｔ通信）と、中継部５２０を経由しない通信経路（ＴＣＰ／ＵＤＰソケット通信）とが存在し、占有制御部５０２は、スキャナ処理部５１０によるスキャナ処理が開始され、このスキャナ処理が完了するまでの間、いずれか一方の通信経路に固定し、他方の通信経路による通信を禁止する。より具体的には、図８に例示するように、ＷｅｂＳｏｃｋｅｔプロトコルで通信する際、最初にアプレットがスキャナ装置３に占有コマンドを投げて占有し、ＵＳＢやクラウド／モバイルなどの他の通信経路で他の端末がスキャナ装置３と通信できないようにした状態で一連のやりとりを行い、すべてのやり取り終了後に占有を解除する。 The occupation control unit 502 sets the communication paths in the first communication unit 512 and the relay unit 520 to the occupied state during the scanner processing by the scanner processing unit 510. In this example, there is a communication path (WebSocket communication) that goes through the relay unit 520 and a communication path (TCP / UDP socket communication) that does not go through the relay unit 520, and the occupation control unit 502 is a scanner by the scanner processing unit 510. Until the processing is started and the scanner processing is completed, it is fixed to one of the communication paths and communication by the other communication path is prohibited. More specifically, as illustrated in FIG. 8, when communicating with the WebSocket protocol, the applet first throws an occupancy command to the scanner device 3 to occupy it, and then uses another communication path such as USB or cloud / mobile. A series of exchanges are performed in a state where the terminal of the above cannot communicate with the scanner device 3, and the occupancy is released after all the exchanges are completed.
　スキャナ処理部５１０は、スキャナ装置３に関するデータ処理を実施する。本例のスキャナ処理部５１０は、複数のアプリケーションプログラム（図中の「アプリＡ」～「アプリＤ」）を含み、画像データの転送処理やスキャナ装置３の設定処理等を行う。なお、スキャナ処理部５１０は、本発明に係るデータ処理部の一例である。 The scanner processing unit 510 performs data processing related to the scanner device 3. The scanner processing unit 510 of this example includes a plurality of application programs (“application A” to “application D” in the figure), and performs image data transfer processing, setting processing of the scanner device 3, and the like. The scanner processing unit 510 is an example of a data processing unit according to the present invention.
　第１通信部５１２は、スキャナ処理部５１０により処理されるデータを第１の通信プロトコルで送受信する。本例の第１通信部５１２は、ＴＣＰ／ＵＤＰソケットインタフェースで、スキャナ装置３の筐体内外に対してデータ通信を行う。より具体的には、第１通信部５１２は、スキャナ装置３の筐体外部にＷｅｂＳｏｃｋｅｔで送信する場合には、ループバックアドレスを指定してＴＣＰ／ＵＤＰソケットインタフェースで、スキャナ装置３内部の中継部５２０に対してデータを送信し、スキャナ装置３の筐体外部にＴＣＰ／ＵＤＰで送信する場合には、外部の宛先アドレス（クライアント端末２のアドレスなど）を指定して、スキャナ装置３外部にデータを送信する。 The first communication unit 512 transmits / receives the data processed by the scanner processing unit 510 using the first communication protocol. The first communication unit 512 of this example uses a TCP / UDP socket interface to perform data communication inside and outside the housing of the scanner device 3. More specifically, when transmitting via WebSocket to the outside of the housing of the scanner device 3, the first communication unit 512 specifies a loopback address and uses a TCP / UDP socket interface to use a relay unit inside the scanner device 3. When transmitting data to 520 and transmitting it to the outside of the housing of the scanner device 3 by TCP / UDP, specify an external destination address (address of the client terminal 2 or the like) and data to the outside of the scanner device 3. To send.

The second communication unit 512 of this example specifies a loopback address and performs data communication with the first communication unit 512 via the TCP / UDP socket interface.
　プロトコル変換部５２４は、中継部５２０が中継するデータを、通信プロトコルに対応した形式に変換する。例えば、プロトコル変換部５２４は、ＴＣＰソケット通信又はＵＤＰソケット通信のポート番号を示す情報を、ＷｅｂＳｏｃｋｅｔ通信で送受信されるデータのヘッダに埋め込む。また、プロトコル変換部５２４は、ＷｅｂＳｏｃｋｅｔ通信で送受信されるデータのヘッダから、ＴＣＰソケット通信又はＵＤＰソケット通信のポート番号を特定し、特定されたポート番号でパケットを生成する。 The protocol conversion unit 524 converts the data relayed by the relay unit 520 into a format corresponding to the communication protocol. For example, the protocol conversion unit 524 embeds information indicating the port number of TCP socket communication or UDP socket communication in the header of data transmitted / received by WebSocket communication. Further, the protocol conversion unit 524 specifies the port number of TCP socket communication or UDP socket communication from the header of the data transmitted / received by WebSocket communication, and generates a packet with the specified port number.
　第３通信部５２６は、第1の通信プロトコルとは異なる第２の通信プロトコルで、外部とデータ通信を行う。本例の第３通信部５２６は、ＷｅｂＳｏｃｋｅｔプロトコルで、クライアント端末６のアプレットとデータ通信を行う。 The third communication unit 526 uses a second communication protocol different from the first communication protocol to perform data communication with the outside. The third communication unit 526 of this example uses the WebSocket protocol to perform data communication with the applet of the client terminal 6.
