Embodiments (a) Description of an Embodiment FIG. 2 is a block diagram of an embodiment of the present invention, in which an image data of a file 10 is added with a cover letter created by a host as code data and transmitted. Shows.

The host 1 is a workstation having a file 10 and is an electronic filing system. Facsimile device 2 connects to host 1
A system line control unit 20, G3 system line control unit 21 for connection with an analog line, G4 system line control unit 22 for connection with a digital line, and a main control unit 30 (micro Processor).

The main control unit 30 includes an operation panel control unit 31 having a keyboard and an LCD display unit, an image data memory 32 including a code area for storing code data for a cover letter, and an image area, and an original. A document reading unit 33, a compression unit 34 for compressing image data, a recording unit 35 for recording data in which received data is restored, a CGROM, CGRAM 37, and a CG decompression unit 36 for decompressing a character code into image data. And a restoration unit 38 that restores received data.

FIG. 3 is a processing flow chart of one embodiment of the present invention, and FIG. 4 is an explanatory view of one embodiment of the present invention, showing an example of broadcast communication. As shown in FIG. 4A, since the host 1 causes the facsimile apparatus 2 to perform facsimile communication, the communication reservation command, the number of destinations, the telephone number, and the next cover letter data are code data. The code data identifier and the cover letter data continue for the number of destinations, the image data identifier indicating that the image data to be transmitted is image data, and the image data for the number of pages follow.

This image data is the file data of the requested file 10, and the cover letter data is the contents of the cover letter shown in FIG. 5 (B). This cover letter has a predetermined format, so the host 1 stores this format in advance,
By calling and entering the caller name, the number of manuscripts, the subject, articles, etc., the required cover letter can be easily created, and even in the case of broadcast, the required number can be easily created.

By printing such a cover letter on paper,
If the document reading unit 33 reads the document, it is useless, and if it is converted into image data, the load on the host 1 becomes heavy. Therefore, the cover letter data is output as code data.

Therefore, a transmission data string as shown in FIG. 4A is created and sent from the host 1 to the line controller 20 of the facsimile apparatus 2. When the facsimile device 2 receives such a data string, the main control unit 30 analyzes the communication reservation command according to the reception flow of FIG. , The code data stored in the control register of the main controller and stored in the code area of the image data memory 32, and the image data stored in the image data memory 32 stored in the image area of the image data memory 32. Store.

At this time, the main control section 30 associates the telephone number of the control register, the cover letter data of the code area, and the image data of the image area with each other, as shown in FIG. 4 (B).

Next, at the time of transmission, the main control section 30
Processing is performed according to the transmission processing flow of FIG. The main control unit 30 takes out the cover letter data of the code area from the head of the control register, converts the character code into image data by the CG developing unit 36, and creates the image data of the cover letter data.

At this time, the code that is not in the CGROM or CGRAM 37 queries the host 1, acquires the image data thereof, stores it in the CGRAM 37, and converts it. And at the beginning of the image data in the image area,
Create a transmission file by adding the expanded cover letter image data.

The main control unit 30 calls the partner facsimile machine from the G3 system line control unit 21 or the G4 system line control unit 22 according to the corresponding telephone number, connects the line, and compresses the contents of the transmission file by the compression unit 34. And send.

After the transmission is completed, the main control unit 30 determines whether the transmission has been completed by the number of destinations, and if not completed, the process returns to the step for the cover letter data of the next destination, and the transmission processing is repeated. ..

On the contrary, when it is determined that the transmission has been completed for the number of destinations, the host 1 is notified of the completion of the transmission and the processing is terminated. In this way, even if the host 1 requests the communication of the cover letter data as the code data and the image data as the transmission content, the image data of the cover letter is created by distinguishing them and attached to the head of the transmission image data. It can then be compressed and sent.

For this reason, even in the transmission of image data, it is not necessary to convert the cover letter data into image data on the host 1 side and output the image data, so that the load on the host is greatly reduced, Other tasks can be executed immediately, and the processing efficiency of the host can be improved.

Further, even in the case of the broadcast communication, since it is only necessary to create the code data of the necessary cover letter, the load on the host can be further reduced and the host processing can be made efficient. (b) Description of Other Embodiments In addition to the above embodiments, the present invention can be modified as follows.

In the above embodiment, the case where the image data is output from the host 1 has been described, but the word processor of the host 1 can be used also in the ordinary facsimile communication in which the document is read by the document reading unit 33 to obtain the image data. It is efficient to create a cover letter with the function, and it can be applied in such a case.

Although the code data has been described as the cover letter data, it may have other contents such as the explanation contents and contact information. It can also be applied to the case where the code data and the image data are separately output from the host 1.

Although the facsimile apparatus provided with the document reading section 33 and the recording section 35 has been described, the present invention can be applied to a facsimile adapter not provided with these. Although the present invention has been described with reference to the embodiments, various modifications are possible within the scope of the gist of the present invention, and these modifications are not excluded from the scope of the present invention.

[0042]

As described above, according to the present invention,
It has the following effects. The facsimile machine determines whether the data from the host is code data or image data and expands the code data into image data, so the host does not have to expand the code data into image data, which is a burden on the host. And the code data can be transmitted as image data.

Since the function of the facsimile machine is used, it can be realized easily and inexpensively.
