Abstract

PURPOSE:To attain the communication between terminal equipments different in code processing capability range by automatically converting a transmission document into a code received by the capability of a terminal equipment at the receiver side, and transmitting it to a terminal equipment at the receiver side. CONSTITUTION:In setting a session at first, the function of a terminal equipment is informed mutually. In such a case, when a character code used for the transmitted document is coincident with the range of code processing capability of a terminal equipment of the receiver side, a main control section 1 decides whether or not the terminal equipment at the receiver side converts the character code in use into a code processed by itself, and when the section 1 decides it to be processed by code conversion, the code conversion of an automatic conversion section 15 is started. In such a case, if the control code differs, the code is converted altogether.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document communication device that mutually communicates 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 such as a keyboard for inputting characters as a code, 3 is a character input control unit that controls the character input unit 2, and 4 is a kanji character input unit. This is a kana-kanji conversion dictionary ROM as an auxiliary means for inputting data. 5 is a document storage section such as a floppy disk for storing documents created by inputting characters; 6 is a storage control section that interfaces between the document storage section 5 and the main control section 1; 7 is, for example, a CRT display. This is a display section that displays a created document. 8 is a display control unit that controls the display unit T, 9 is a communication control unit, and 10 is a modem (modulator/demodulator) depending on the line used, for example, when communicating using an analog telephone network. , a line correspondence section controlled by the communication control section 9; 11 a recording section that outputs a hard copy of a document; 12 a recording section 1;
A recording control section 1 controls the recording control section 1, and a main storage section 13 stores programs and the like for overall control.

Next, the operation will be explained. Document information to be transmitted is keyed in in advance from the character input section 2, encoded using the kana-kanji conversion dictionary '84, and stored in the document storage section 5 as a transmission document. At this time, the character code set to be used depends on the code expression capability of the device.

For communication, the communication control unit 9 sets up a call as shown in the flowchart of FIG. 6, sets up a session (step 5TI), and mutually notifies terminal device functions regarding non-standard expression capabilities (step 5TI). 5T2). Next, check whether or not the other party's device satisfies the code expression function used in the transmitted document (step ST3). If it satisfies the code expression function used in the transmitted document, the transmitted document stored in the document storage section 5 is The call is transferred directly via the line handling section 10 (steps ST5, ST6), and if they do not match, the session is terminated as communication is not possible (step 5T6), and the call is disconnected. In such a case, document communication is not possible. 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 Kanji codes, communication will not be possible.

In addition to this, there are cases where the one-to-one code correspondence is different (EBC
Various cases can be considered, such as communication between a terminal that can handle K, Japanese (kanji, katakana, hiragana) characters other than DIC←ASCII, JIS code←shift JIS code, and a terminal that can only handle alphabets. When creating a document, the code expression function of the receiving device is often not considered, and when communicating documents from a high-performance terminal to a simple terminal, communication may not be possible due to inconsistency in the functions.

[Problem that the invention seeks to solve]

Conventional document communication devices are configured as described in 5 above, so if the character code and control code used in the sent document do not match the code processing capability range of the receiving terminal device, communication cannot be performed. There was a problem.

This invention was made to solve the above-mentioned problems, and when the character code and control code expression function used in the sending document do not match the code processing capability range of the receiving terminal device, It is an object of the present invention to provide a document communication device that automatically converts a transmitted document into a code that can be received by the capabilities of a receiving terminal device and transmits the code to the receiving terminal device.

[Means for solving problems]

The document communication device according to the present invention uses mutual notification of terminal device functions to transmit a transmitted document to a receiving terminal device when a code used in the transmitted document does not match the code processing capability range of the receiving terminal device. The code is automatically converted into a processable code before being transferred.

[For production]

The document communication device according to the present invention automatically converts the code of a transmission document that has already been encoded in the automatic code conversion unit into a sentence containing only kana, for example from a sentence containing kanji and kana, according to 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. 1st
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 correspondence section, 11 is a recording section, 12 is a recording control section, and 13 is a main storage section.These are the same or equivalent parts as the conventional one with the same reference numerals in FIG. Further explanation will be 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 is this conversion dictionary 1.
This is an automatic conversion unit that converts characters and control codes using 4.

Next, the operation will be explained. First, document information to be transmitted is keyed in from the character input section 2, encoded using the Kana-Kanji conversion function of the conversion dictionary 14, and stored in the document storage section 5 as a transmission document. In creating this transmission document, the terminal capacity is generally used to the fullest extent, and the terminal capacity of the side receiving the created transmission document is generally not considered very much.

In communication, after setting up a call, the communication control unit 9 first sets up a session as shown in the flowchart of FIG. 2 (step 5TI).

Next, mutual notification of terminal device functions is performed (step ST7).
), the terminal device function is confirmed (step 5T3
). At this time, if the character code used in the sent document matches the code processing capability range of the receiving terminal device,
Transfer the transmitted document (steps ST4, ST5)
When the transmission of the transmitted document is completed, the session is terminated and the call is disconnected (step 5T6). This series of processing sequences is shown in FIG. 3 (al). Also, step ST
If the results of checking the terminal device functions in step 7 do not match, it is determined whether or not the character code used in the transmitted document on the sending side can be converted into a code that can be processed by the terminal device on the receiving side (step 5T8). If the result is not possible, the session is terminated (step 5T6) and the call is disconnected. FIG. 3 [bl shows this series of processing sequences.

If code conversion is possible, the automatic conversion unit 15 starts automatic code conversion (step 5T9). That is,
If the code used in the sent document includes kanji and the receiving terminal device only supports katakana and hiragana, use the kanji/kana conversion function of the conversion dictionary 14 to convert the code as shown in Figure 4. As shown, a document containing kanji and kana is code-converted into a document containing only hiragana and katakana that can be processed by the receiving terminal device. Similarly, if the terminal device on the receiving side supports only alphabets, the conversion dictionary 14's kana-to-romanization conversion function is used to convert the code into a document with only alphabets in romaji. At this time, if the control codes are different, they are also code converted. Next, it is determined whether such conversion can be performed in real time in a short time (step 5TIO), and if possible, the line handling unit 1
0, the converted document is sequentially transferred to the receiving terminal device (steps ST4 and ST5). When the transmission of the transmitted document is completed, the process ends in step 5T6).
Hang up the call. This series of processing sequences are shown in Figure 3.
It is shown in

Further, as a result of the determination in step 5 TIO, if it is determined that the conversion takes a long time and real-time code conversion is not possible, the communication control unit 9 ends the seven-pass conversion (step 5T6) and temporarily The call is disconnected and the automatic conversion unit 1
Wait for the end of the code conversion process in step 5. Communication control unit 9
When the code conversion process is completed, the call is automatically set up again and the session is set up (step 5TI).

Next, mutual notification of terminal device functions is performed (step 5T7).
), confirm the terminal device function (step 5T3)
. At this time, the character code used in the transmitted document has been converted to match the code processing capability range of the receiving terminal device, so the process is performed in step ST4.8T5.
Then, the code-converted transmission document is transferred.

When the transfer of the transmitted document is completed, the session is terminated (step 5T6) and the call is disconnected. This series of processing sequences is shown in FIG. 3 (dl).

In addition, in the above embodiment, an example of conversion from a document containing Kanji and Kana to a document containing only Hiragana and Katakana is shown in FIG. If the device supports only kanji up to JIS level 1, only the JIS level 2 kanji used in the transmitted document is converted into kana.

In the above embodiment, a ROM is used as the conversion dictionary, but a RAM or other storage medium may be used, and the same effects as in the above embodiment can be achieved.

〔Effect of the invention〕

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 terminal device do not match, the transmitting side automatically converts the code, Since the system is configured to convert the document into a transmission document that can be processed by the receiving terminal device and send it, it is possible to communicate between terminal devices with different code processing capabilities, and it is also possible to communicate with simple document communication devices. It has the effect of becoming.
