The image number is searched, and the data indicating the video coding terminal 4 to which the image number is distributed and the data are output to the memory control unit 31 as the distribution contents. When the content of the distribution is output, the video distribution control unit 33 deletes the image number from the category classification table 33a. Further, the memory control unit 31 outputs the image and the image number stored in the image memory 32 to the corresponding video coding terminal 4 according to the distribution contents.

Also, when an image distribution request signal from another video coding terminal 4 is obtained, the same operation as described above is performed. As a result of the distribution of the image as described above, the image display unit 4a of the video coding terminal 4 processes the code data supplied from the image memory 32 by the image decompression circuit 51, and outputs the header attached to the code data. The image of the postal matter P expanded according to the flag indicating the compression method and the compression parameter is displayed on the image display unit 4a using a monochrome screen.

Then, the operator inputs a code corresponding to the address and postal code which could not be recognized in accordance with the display through the input unit 25. Then, the code and image number corresponding to the address or postal code input by the input unit 25 of the video coding terminal 4 are output to the coding content storage control unit 34 via the desk input / output control unit 35.

Thus, the coding content storage control unit 34 stores the code and the image number, and outputs to the video distribution control unit 33 that the code has been input for the image number, that is, an image distribution request signal.

Codes corresponding to the address and postal code which could not be recognized by the other video coding terminals 4 are input, and the operation is the same.
