【Example】

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

<Structure> FIG. 2 is a diagram showing a document processing apparatus having a communication function according to an embodiment of the present invention connected to a local area network (LAN). In FIG. 2, reference numeral 0 denotes the document processing apparatus of this embodiment, which is connected to the LAN 9 via the communication adapter 8. 10a to 10c are document processing devices of the embodiment like 0, but these are illustrated without the communication adapter. Thus, the document processing device 0
The document processing apparatuses 10a to 10c are connected to each other via a LAN, and can communicate with the document processing apparatus 0 using the document processing apparatuses 10a to 10c as terminals, for example.

FIG. 1 is a block diagram showing one of the document processing apparatuses with a communication function shown in FIG.

In FIG. 1, 11 is a keyboard (KB) for inputting data, commands and the like. A reception processing unit 12 has a format in which the input processing unit 13 can process document processing information and screen control information sent from another device connected by communication via a serial IO (SIO) 19. It is passed to the input processing unit 13.

The input processing unit 13 temporarily stores the document processing information and screen control information input from the KB 11 in a buffer (keyboard buffer) 131, and stores the stored information in the document processing unit 14 or a screen control unit 15 described later. Alternatively, it is passed to the transmission processing unit 18 described later. In addition, the document processing information and screen control information received from the reception processing unit 12 are also stored in the buffer 1.
The data is temporarily stored in 31 and is sent to the document processing unit 14 and the screen control unit 15 to be left for the processing.

The document processing unit 14 uses the document memory 14 based on the input information of the document processed by the input processing unit 13.
Document processing such as creation and editing of the document stored in 1 is performed.

The screen control unit 15 controls the screen display such as scrolling of the document screen displayed on the display unit 17 according to the screen control information passed from the input processing unit 13.

The transmission processing unit 18 converts the document processing information to be transmitted, which has been passed from the input processing unit 13, into a format for transmission and transmits it via the SIO 19.

A display control unit 16 displays an image such as data to be displayed on the display unit 17 based on the document data input from the document processing unit 14 and the document processing information input from the screen control unit 15. To do.

Reference numeral 20 denotes a communication management unit, which performs communication control such as selection of a partner terminal for communication and setting / releasing a link of the LAN 9 by the communication adapter 8.

Next, details of the operation of the present embodiment having the above-mentioned configuration will be described with reference to the flow charts of FIGS.

<Explanation of Flowchart> FIG. 3 is a flowchart of a process performed by the document processing apparatus of the embodiment connected to the network as shown in FIG. 2 when an input for document processing is made.

First, in order to start communication, the SIO 19 and the communication adapter 8 are initialized in step S31. Next, in step S32, with the document processing apparatus being operated as the host, the document stored in the host is processed according to the document processing information received from the terminal device or the document processing information input from the keyboard 11 of the host itself. The communication management unit 20 selects whether to perform an operation such as editing or to operate a document stored in the host as a terminal by communication.

When the host is selected, the processing on the host side, which will be described later with reference to FIG. 4, is performed in step S33. If the terminal is selected, the processing on the terminal side, which will be described later with reference to FIG. 5, is performed in step S34.

When the processing of either step S33 or step S34 is completed, the document processing in the document processing apparatus of this embodiment is completed.

<Process of Host Side Device> Next, the details of the operation of the host side process will be described with reference to the flowchart of FIG. It is assumed that the document processing apparatus 0 in FIG. 2 is selected as the host and the document processing apparatus 10a is selected as the terminal. However,
The processing described here is limited to the document processing input received from the terminal through communication, and the description of the document processing instruction input from the keyboard 11 of the host itself is omitted. However, it is needless to say that the procedure of document processing itself is the same, except that they are different in the route to the input processing unit 13.

First, in step S41, the communication management unit 20 selects a partner document processing apparatus to be a terminal. Here, for example, the document processing device 10a is selected. When the terminal is selected, in step S42, a link is set between the selected terminal and the host to enable communication, and in this state, the reception of a signal from the terminal is awaited. In step S43, when the document processing information from the partner terminal is input via the LAN 9, communication adapter 8 and SIO 19, the reception processing unit 12
The received document processing information is passed from the input processing unit 13 to the input processing unit 13, and the input processing unit fetches and temporarily stores it. The input processing unit 13 distributes the captured information to any of the document processing unit 14, the screen control unit 15, and the transmission processing unit 18, and if the captured information is the document processing information, inputs the information to the document processing unit 14. To do. In step S44, the document processing unit 14 edits the document stored in the document memory 141 and creates a document. For example, if the received document processing information is “open document file“ A ””, the document memory 141 is searched for the document file “A”, if it is opened, if not, a new file is created and opened. After the document is opened, if the document processing information indicates the processing such as "replace character string" B "with" C "", the processing is performed as it is.

In step S45, the connection of the link between the document processing apparatus 0 as the host and the document processing apparatus 10a as the terminal is tested. If not disconnected, the process returns to step S43 and the document processing operation is performed again by communication from the terminal. On the other hand, if the link is disconnected, it is determined in step S46 whether or not to continue the document processing, and if it is to continue, the process returns to step S41 to select the terminal for the next document processing input. If you do not continue, terminate the application as the host. This step S46
May let the operator decide to continue the process. Also, the test in step S45 is a test assuming that the link is released from the terminal side, but step S4
The link may be released from the host side after the document processing in 4 is completed. In this case, step S4
The test result of 5 is naturally "YES".

<Processing of Terminal Side Device> Next, the details of the operation of the processing on the terminal side will be described with reference to the flowchart of FIG.

First, in step S51, when the document processing apparatus 0, which is a host, is selected as a terminal for document processing and receives a link setting request, a link is set with the host in response to the request. When a link is established with the host via the LAN 9, communication with the host is established, and when the document processing operation is performed from the keyboard 11 of the document processing apparatus 10a which is the terminal in step S52, the input processing unit 13 causes The input document processing information is temporarily stored in the input buffer 131. Next, in step S53, the document processing information is passed from the input processing unit 13 to the transmission processing unit 18, and is transmitted to the document processing apparatus 0 which is the host via the SIO 19. In step S54, the state of the link is tested, and if the link is not broken, step S52
Then, the operation is returned to the state where the input from the keyboard 11 is possible again. If the link is disconnected, proceed to step S55,
Test whether to continue processing documents from the terminal. If continuing, the process returns to step S51 and waits for the host to select again as a terminal and set the link. On the other hand, if the process is not continued, the process ends there. Although the link status is tested in step S54, the link can be released from the host side or the terminal side. If the link is released from the terminal side, if the document processing information has been transmitted in step S53, the link is released. It issues a release request to the host and releases it. In this case, of course, the test result in step S54 is "YES".

With the above procedure, it is possible to perform document processing between the document processing devices connected by the LAN.
