Description

Description: TECHNICAL FIELD The present invention relates to a document communication device for mutually communicating coded document information.

[Conventional technology]

FIG. 5 is a block diagram showing a conventional document communication device. In the figure, 1 is a main control unit that controls the whole, 2 is a character input unit for inputting characters as codes, such as a keyboard, 3 is a character input control unit that controls the character input unit 2, and 4 is a Kanji character. It is a Kana-Kanji conversion dictionary ROM as an auxiliary means for inputting. Reference numeral 5 is a document storage unit such as a floppy disk for storing a document created by character input, 6 is a storage control unit that interfaces between the document storage unit 5 and the main control unit 1, and 7 is a CRT display or the like A display unit for displaying a document. 8 is a display unit 7
The display control unit 9 controls the communication, the communication control unit 10 includes a modem (modulator / demodulator) or the like according to the line to be used, for example, when communicating using an analog telephone network. The line-corresponding section controlled by the, 11 is a recording section for outputting a hard copy of a document, 12 is a recording control section for controlling the recording section 11, and 13 is a main storage for a program for controlling the whole. It is a storage unit.

Next, the operation will be described. The document information to be transmitted is keyed in in advance from the character input unit 2, encoded using the Kana-Kanji conversion dictionary 4, and stored in the document storage unit 5 as a transmitted document. At this time, the code set of the characters used depends on the code expression capability of the device.

In communication, the communication control unit 9 sets up a call as shown in the flowchart of FIG. 6, then sets up a session (step ST1), and performs mutual notification of terminal device functions regarding non-standard expression capabilities (step ST1). ST2). next,
It is checked whether the partner device satisfies the code expression function used in the transmitted document (step ST
3) If satisfied, the transmission document stored in the document storage unit 5 is transferred as it is through the line interface unit 10 (steps ST5 and ST6). It ends (step ST6) and disconnects the call. In such a case, document communication cannot be performed. For example, as shown in FIG. 7, if a Kanji code is used in the transmitted document and the terminal device on the receiving side cannot handle the Kanji code, communication cannot be performed. In addition to this, when one-to-one code correspondence is different (EBCDIC ASCII, JIS code shift JIS code), communication between terminals that can handle Japanese (Kanji, Katakana, Hiragana) characters and terminals that can only handle alphabets, etc. Various cases are possible. When creating a document, the code expression function of the receiving device is often not considered, and when document communication is performed from a high-performance terminal to a simple terminal, the communication may not be possible due to a mismatch in functions.

[Problems to be solved by the invention]

Since the conventional document communication device is configured as described above, there is a problem that communication cannot be performed unless the character code and control code used in the transmitted document and the code processing capability range of the receiving side terminal device match. There was a point. Further, even if code conversion is performed at the time of transmission, it is conceivable that the speed of the code conversion process does not catch up with the data transfer speed and the transmission data may be lost.

The present invention has been made to solve the above problems, and when the character code and control code expression functions used in the transmitted document do not match the code processing capability range of the receiving side terminal device, The transmitted document is automatically converted into a code that can be received by the receiving terminal device and sent to the receiving terminal, and even if the code conversion processing speed cannot keep up with the data transfer speed, there is no inconsistency in the transmitted data. The purpose is to obtain a document notification device.

[Means for solving problems]

According to the document communication device of the present invention, when the code used for the transmission document does not match the code processing capability range of the reception side terminal device by the mutual notification of the terminal device function, the transmission document is transmitted by the reception side terminal device. The code is automatically converted into a code that can be processed and then transferred.

[Work]

A document communication apparatus according to the present invention automatically performs code conversion of a transmission document already encoded by an automatic code conversion unit, for example, from a kanji / kana mixed sentence to a sentence containing only kana in accordance with the expressive ability of the receiving side. Communicate the converted document.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
In the figure, 1 is a main control unit, 2 is a character input unit, 3 is a character input control unit, 5 is a document storage unit, 6 is a storage control unit, 7 is a display unit, 8 is a display control unit, and 9 is a communication control unit. , 10 is a line interface unit, 11 is a recording unit, 12 is a recording control unit, and 13 is a main memory unit, which are the same as or equivalent to the conventional ones shown in FIG. Detailed description is omitted. 14 is a conversion dictionary such as Kana / Kanji conversion, Kanji / Kana conversion, Kanji / Romaji conversion, Kana / Romaji conversion, etc., which is configured by ROM, and 15 uses this conversion dictionary 14,
An automatic conversion unit that converts characters and control codes.
The determining means is realized by the main controller 1 and the communication controller 9.

Next, the operation will be described. First, the document information to be transmitted is keyed in from the character input unit 2, encoded using the kana / kanji conversion function of the conversion dictionary 14, and stored in the document storage unit 5 as a transmission document. In creating the transmission document, it is general that the terminal capacity is used sufficiently and the terminal capacity on the side of receiving the created transmission document is not so conscious.

In communication, as shown in the flowchart of FIG. 2, the communication control unit 9 first sets a call and then sets a session (step ST1). Then, mutual notification of the terminal device function is performed (step ST2), and the terminal device function is confirmed (step ST7). At this time, if the character code used in the transmitted document matches the code processing capability range of the receiving side terminal device, the transmitted document is transferred (steps ST4 and ST5), and when the transfer of the transmitted document is completed, the session is completed. Is terminated (step ST6) and the call is disconnected. This series of processing sequences is shown in FIG. Further, if the result of confirmation of the terminal device function in step ST7 does not match, it is determined whether or not the character code or the like used in the transmission document at the transmission side can be converted into a code that can be processed by the reception side terminal device ( In step ST8), if the result is no, the session is terminated (step ST6) and the call is disconnected. FIG. 3B shows this series of processing sequences.

If the code can be converted, the automatic conversion unit 15 starts automatic code conversion (step ST9). That is, when the code used in the transmitted document includes Kanji and the terminal device on the receiving side supports only Katakana and Hiragana, the Kanji / Kana conversion function of the conversion dictionary 14 is used to generate the fourth character. As shown in the figure, a document containing a mixture of kanji and kana is code-converted into a document that can be processed by a receiving terminal device consisting of only hiragana and katakana. Similarly, if the terminal device on the receiving side supports only alphabets, use the Kana / Romaji conversion function of the conversion dictionary 14,
Converts the code into a document in Roman alphabet only. At this time, if the control code is different, that code is also converted. Next, it is determined whether such conversion can be performed in real time in a short time (step ST10), and if possible, the documents converted through the line interface 10 are sequentially received by the terminal on the receiving side. Transfer to the device (steps ST4, ST5). When the transfer of the transmitted document is completed, the session is ended (step ST6) and the call is disconnected. This series of processing sequences is shown in FIG.

If the result of determination in step ST10 is that conversion takes a long time and real-time code conversion cannot be performed, the communication control unit 9 terminates the session (step ST6) and disconnects the call. , Waits for the end of the code conversion processing by the automatic conversion unit 15. When the code conversion process is completed, the communication control unit 9 automatically sets the call again,
Set the session (step ST1). Then, mutual notification of the terminal device function is performed (step ST2), and the terminal device function is confirmed (step ST7). At this time, since the character code used in the transmission document is code-converted so as to match the code processing capability range of the receiving-side terminal device, the process proceeds to steps ST4 and ST5, in which the code conversion of the transmission document is performed. Transfer is done. When the transfer of the transmitted document is completed, the session is ended (step ST6) and the call is disconnected. This series of processing sequences is shown in FIG.

In the above embodiment, an example of converting a document containing kanji and kana into a document containing only hiragana and katakana is shown in FIG. 4, but the terminal device on the communication side supports up to the second level of kanji JIS and the terminal on the receiving side. If the device supports only JIS Kanji JIS Level 1, only the JIS Level 2 Kanji characters used in the transmitted document are converted to Kana.

In the above embodiment, the ROM is used as the conversion dictionary, but a RAM or other storage medium may be used, and the same effect as that of the above embodiment can be obtained.

〔The invention's effect〕

As described above, according to the present invention, when the character code used in the transmitted document and the code processing capability range of the receiving side terminal device do not match, the transmitting side automatically performs code conversion, It is configured to convert the transmission document that can be processed by the receiving side terminal device and transmit it, and disconnect the call once when it is judged that the speed of the code conversion process cannot keep up with the data transfer speed. Communication between terminal devices with different capacity ranges is possible, simple communication with document communication devices is possible, and even if the code conversion processing speed cannot keep up with the data transfer speed, the data received by the receiving side This has the effect of not causing contradiction.
