FIGS. 4(A) and 4(B) are flowcharts showing data communication control in this embodiment.
, CB), the data communication procedure of this embodiment will be explained.

First, the data transmission process of this embodiment will be explained with reference to FIG. 4(A).

The operator executes processing for creating document data to be transmitted in step S1. For example, when creating the document data shown in FIG. 3, encoded character data input from the keyboard 14, for example block 31, is stored in the VRAM 4. This may be entered sequentially from the keyboard 14,
It may be stored in advance in the hard disk device 2 or floppy disk device 3 and read from there.

The image data block 32 is read by the reader 12, reads out the data stored in the image memory 9, and is read out using the mouse 15 and keyboard 14 while viewing the image on the CRT 5. Input the position and size of blocks (character blocks, image blocks) and synthesize them. When the creation of the transmission document is completed, the process proceeds to step S2, and the position information a and the size information shown in FIGS. appended to the position.

Further, position information a and size information a are added to the character data and image data of the block.

Character format information d1 is added to the character data, and the image data read by the reader 12 is compressed and encoded by the image compression unit 27, but information d2 indicating the encoding method and the horizontal , information f indicating the scanning density in the vertical direction is also added.

On the other hand, when transmitting audio data, in the processing of steps S1 and S2, the signal input by the microphone 19 is amplified by the amplifier 18, passed through the filter 17, and then
/D converter 16 digitizes the data. Then, d3, which is information indicating the digitization method, is generated and added.

Furthermore, information c1 indicating that it is character data, information C2 indicating that it is image data, and information C3 indicating that it is voice data are added to the top of the character data, image data, and audio data, respectively. Ru.

Each of the above-mentioned additional information is generated and added by the CPU 1, a transmission document is created, and the document is stored in the hard disk device 2. Then, in step S3, it is checked whether the document creation has been completed, and if it has not been completed, the process returns to step S1 again and the next document is created. When the document creation is completed and the document is to be sent, the process proceeds to step S4, where the operator operates the keyboard 14 and instructs the CPUI to read the transmission document data from the hard disk device 2. The data to be transmitted at this time is shown in Figure 2 (a), which was input using the keyboard 8.
Source information data A and page data B are added.

Next, in step S5, the CPUI calls the destination receiving terminal to which the data is to be sent via the communication control unit 24 and the line 25, and connects them to each other, and in the subsequent step S6, confirms the terminal function of the destination. Next step S
As a result, in step 7, it is determined whether or not the other party's terminal has a function to receive voice information, and if it has a function to receive voice information, the process proceeds to step S.
The transmission document containing the audio information created in advance in step 8 is transmitted as is. However, if the other party's terminal does not have a function to receive voice information, the process proceeds from step S7 to step S9, where the voice recognition unit 6 recognizes the voice data and converts it into character code information corresponding to the input voice information. , CPUI
Add the page position data a, size indicator b, information C1 indicating that it is a character, and information d1 indicating the character format shown in Figure 2 (a), and convert the character code information to a format that matches the format. The converted data is converted into transmission block data of character data e and transmitted.

Note that in the terminal function negotiation in step S6, the transmitting terminal device outputs a control frame transmission request indicating all the functions of the receiving terminal device to the receiving terminal device, and the receiving terminal device responds to the control frame transmission request. This is done by sending out a transmission control frame that includes the functions of the device itself as a response. Here, it is sufficient to simply check whether the other party's device has a function to receive audio information.

Next, the reception processing of this embodiment will be explained with reference to FIG. 4(B).

In receiving, first, in step S20, the communication control unit 24 checks whether or not reception is detected from the line 25. If there is no reception from the line 25, the process proceeds to step S21, and whether or not there is an output command from the keyboard 14 is determined. Find out. Here, if there is no instruction manpower, the process returns to step S20 again, and whether this instruction input or line 25
Wait for more information to be received.

When data is received from the line 25, the process proceeds from step S20 to step 322, where the above-described terminal function negotiation process from the transmitting side device is performed. And step S
At step 23, the subsequently sent data is received. The received data is stored as it is in the hard disk device 2 in step S24, and when all the data has been received and stored in the hard disk device 2, the process proceeds to step S25, where the CR
``Received'' is displayed on the display screen of T5.

Then, the data reception process is completed, and the next step S26 is
The line 25 is restored and the process returns to step S20.

On the other hand, the operator recognizes that data has been received by the "received" display on the CRT5, and transfers the received data to the CRT.
5, or when printing using the printer 13, or when outputting audio data as audio from the speaker 23, specify the received manuscript data from the keyboard 14 and instruct execution of display, printing, and audio output. . If this key power is present, the process advances from step S21 to step S30, and after confirming that there is received data in the hard disk drive 2 in step S30, the designated data is read out from the hard disk drive 2 in the following step S31. Incidentally, if the output instruction input is made by mistake even though there is no received data, the key manual input is invalidated and the process returns to step S20.

When the CPU 1 reads the designated data from the hard disk device 2, it determines whether the data in the block is character data or image data based on the data identification information C1, C2, and C3 added to the block in step S32. Determine whether it is audio data. As a result of the determination, if the instruction is to output audio data, step S3
3, the process proceeds to step S34, where the audio data h is stored in the audio memory 7 together with the digitized information d3. Then, in the subsequent step S35, the audio data is read out from the audio memory 7, and is D/A based on the digitized information d3.
The signal is converted into analog by a converter 20, passed through a filter 21, amplified by an amplifier 22, and outputted by a speaker 23. Note that the voice data can be converted into character encoded information by the voice recognition unit 6 and then displayed on the CRT 5 or printed by the printer 13.

If the output instruction is not audio data, the process advances from step S33 to step S36, and if the output instruction is character data, the character code is developed with font data stored in the program memory 8 based on the character format information. , is developed as dot data in the area of the image memory 9 determined by the position information a and the size information I. If the block data is image data, the image data compressed by the image compression unit 27 is decompressed based on the encoded information d2 and the pixel density data f, and the position information a and size information are expanded. It is stored as dot data in the area of image memory q defined by . Then, in the following step S37, the output light is output from the printer 13 or from the CRT 5.
If the data is to be displayed on the CRT 5, the process proceeds to step 33B, where the display data is read from the image memory 9, stored in the VRAM 4, and displayed. On the other hand, when printing is to be performed by the printer 13, the process advances from step S37 to step S39, where the data is read from the image processor 9 and output to the printer 13. After the output is finished, the process returns to step S20 and the next reception process or output instruction input is performed. Be prepared.

Note that if the other party's terminal is a pure facsimile machine or the like that does not have the ability to receive character-encoded information, the character-encoded data may be expanded into a font and sent entirely as image data.

In the above explanation, when reading the received data from the hard disk device 2, for example, all the data shown in FIG. It may also be possible to control the extraction and output of only the specified part.

As explained above, according to this embodiment, the data communication device,
For example, in a mixed-mode terminal device, not only text using a character encoding method or text using a facsimile encoding method, but also text with audio information,
It becomes possible to create, send and receive only audio information, and in addition, if the other party's terminal does not have the ability to receive audio information,
The ability to convert voice information into character encoded information has the effect of allowing communication with any partner terminal.

[Effects of the Invention] As described above, according to the present invention, data communication can be performed in a data format that conforms to the functions provided by the communication destination device, and data communication including voice information is also possible.
