In step S21, when the client station 1 requests the server apparatus 8 to transmit a facsimile, in step S22, if facsimile transmission is possible, the server apparatus 8 transmits the facsimile to the client station 1.
FAX transmission OK sign and MMR encoding request are sent to. Next, in step S23, the image processing section 4 of the client station 1 recognizes the file name of the bitmap file to be encoded. Then, in step S24, the image processing section 4 of the client station 1 encodes the bitmap file by the designated size of one page,
It is stored in the main storage unit 3. As shown in FIG. 3, the encoded file name is obtained by adding a two-digit page number to the unique file name excluding the extension using a page counter described later, followed by the extension. mmr is added. 1
When the encoding for the page is completed, the client station 1 in step S25 transmits the encoded MM for one page.
Transfer the R file to the server device. Next, step S2
At 6, the image processing unit 4 of the client station 1
Checks whether encoding has been completed for the input bitmap file. If the size of the input bitmap file cannot be completed by encoding for one page, a page counter for counting how many pages has been encoded is incremented in step S27, and in step S28, the page counter is counted for encoding. The used memory area is released, and the file pointer indicating the position in the file is advanced by one page in order to read data from the bitmap file input in step S29. Then, the process returns to step S24 to encode the next page. This is repeated until the bitmap file is completely encoded. When it is confirmed in step S26 that the encoding has been completed, in step S30 the client station 1 sends the server device 8
To the client station 1 from the server 8 to inform the client station 1 of the number of MMR files that have been encoded and transferred to the server 8 in step S31. In step S32,
The number of MMR files transferred to the server device is compared with a page counter that counts the number of pages encoded by the image processing unit 4 in the client station 1. If they match, the WAN terminal 16 (FAX) is passed through the WAN 14 in step S33. The client station 1 sends an outgoing call OK sign to the server 8 notifying that the MMR file can be transferred to a terminal or the like. If the number of MMR files transferred to the server device in step S32 does not match the number of pages encoded in the client station 1, in step S34, an error end sign indicating that MMR encoding has failed is sent to the client station 1. To the server device 8.

Here, in FIG. 3, "ij" is changed to "0".
In the case of 3 ", the number of files before encoding is one and the number of files after encoding is three, and the FAX transmission NG processing is performed as an error due to a mismatch in the number of files.
When “ij” is “01”, the fax transmission OK processing is performed as normal due to the coincidence of the number of files.

With the above processing, character or image data can be divided into pages of a designated size and converted into MMR files.

That is, as described above, according to the present embodiment, a character or image data is converted while being divided into pages of a designated size, so that a file is transferred every time conversion of one page is completed. MMR between the client and the server, reducing the memory occupied on the client station, enabling the encoding of large data, reducing the effect on processes running simultaneously in multitasking. This enables error detection in file transfer.

[0019]

As described above, according to the present invention, 1
Each time a file is converted, the file can be transferred to the server, the memory occupied on the client station can be reduced, large-size data can be encoded, and a wide area network is connected. Since transmission is permitted after confirming that data to be transmitted to the terminal is normally prepared, it is possible to prevent erroneous data from being transmitted.
