This is a flowchart that performs facsimile transcoding of text codes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the second and third embodiments of the present invention will be described in detail with reference to the accompanying drawings.

When the message is sent to the MCP 12 and the ICP 24 by the operation of FIG. 1 described above, the message of the MCP 12 is input to the ICP control unit 38 through the interface 36.

At this time, the ICP controller 38 receives a message from the MCP 12 in FIG. 52. Upon receiving the message sent from the MCP 12, the ICP controller 38 extracts a command message from the received message in FIG. 54. In other words, if there is a transcoding message, the extracted transcoding message is extracted, and in step 56, it is searched whether the instruction type is a facsimile code conversion command or a text code conversion to facsimile code or a statement processing command.

If the analysis of the command form in step 56 is a facsimile code conversion command, the ICP control unit 38 outputs the received facsimile image data to the coding / decoding unit 40, the coding / decoding 58 unit input image In step 58, the data is controlled to be decoded (if the command is transcoding, the image data of the message means the code of the facsimile).

At this time, the decoding control of the coding / decoding unit 40 is controlled by the ICP control unit 38 to be up to 64 Kbytes. The coding / decoding unit 40 under the control of the ICP control unit 38 decodes the image data, which is received data of the received facsimile, and stores up to 64 Kbytes in the image memory (IM) 42.

When the decoded data is stored in the image memory 42, the ICP controller 38 controls the coding / decoding unit 40 to code the decoded data into a code scheme requiring code conversion in the MCP 12. Control in step 60.

At this time, the coding / decoding unit 40 executes coding of the decoded data stored in the image memory 42 according to a command of the ICP control unit 38 using a predetermined code scheme.

On the other hand, the ICP control unit 38 which controls the coding in FIG. 360 detects whether all data received from the MCP 12 has been processed in FIG. Until all the data has been transcoded.

If it is determined in step 62 that the code conversion of all input data has been processed, the ICP control unit 38 transmits the code data converted into another code in step 64 to the first degree MCP 12 through the interface 36. .

The procedure jumps to step 52 described above to receive a message from the MCP 12 through the interface 36.

On the other hand, when the command extracted from the received message in the command form analysis process of step 56 described above is a command for converting a text code into a facsimile code or output document processing and determination, the ICP control unit 38 also receives an input through the interface 36. Parse data one byte at a time.

At this time, the reason why the ICP control unit 38 analyzes the received data by byte is that the received data is ASCII code and self-definition of the premises document processing device when the text code is converted into a facsimile code or the output form is processed. This is because it consists of control codes.

The ICP control unit 38, which is analyzed by byte received through the fraud interface 36, can extract font data of the input character code from the CGROM 46 when the analysis result received data is a character code value. The pattern generator 44 is controlled in the process. The pattern generator 44 under the control of the ICP controller 38 accesses the font data corresponding to the character code from the CGROM 46 and outputs the font data to the image forming unit 48.

The image forming unit 48, which has input font data corresponding to the character code from the pattern generating unit 44, stores the font data in an arbitrary place in the graphic memory (GM) 50.

When the pattern generator 44 generates font data for one page (based on the A4 document size) under the control of the ICP controller 38, the image forming unit 45 controls the graphics memory under the control of the ICP controller 38. Font data stored at any position of 50 are arranged in the corresponding position in FIG. 68.

That is, a bitmap of A4 size is formed.

When the image forming unit 48 completes the font arrangement in the graphic memory 50, the ICP control unit 38 codes the bitmap arranged in the graphic memory 50 into a code system requested by the MCP 12. The control unit / decode unit 40 is controlled in FIG. 70.

At this time, the coding / decoding unit 40 accesses the bitmap stored in the graphics memory 50 through the image forming unit 48 under the control of the ICP control unit 38 and codes the code system requested by the MCP 12. Will be

On the other hand, the ICP control unit 38 except for coding in FIG. 3 70 detects whether the code conversion of all input data is completed in FIG. 72, and when completed, the interface 36 converts the data converted into facsimile code. Transmits to the MCP 12 via.

If all the input data have not been processed in step 3 of FIG. 72, the ICP controller 38 searches whether the data coded in step 76 exceeds the range (8 Kbytes) of the interface protocol.

If the data coded in the search decision in step 76 does not exceed 8 Kbytes, the ICP control unit 36 jumps to step 66 described above, and outputs the font data for the input character code through the pattern generator 44 through the CGROM 46. Withdraw from the next process.

If the coded data in step 76 is 8Kbyte or more, the ICP controller 38 transmits the coded coded conversion data to the MCP 12 through the interface 36 in step 78 and jumps to step 66 to receive the received character. Repeat until the data is converted into facsimile code data.

In this case, the coded data is transmitted in 8Kbyte units because the data interface protocol with the MCP 12 is defined as 8Kbytes, and may be changed in transmission units according to the interface protocol definition.

If the control code according to the command form analysis result in the process in step 56 described above, the ICP control unit 38 calculates and moves as many cursor positions as necessary.

In addition, if it is not a command of analysis result of 56-step command form code conversion, text code facsimile code conversion / document processing, the ICP control unit 38 generates an unprocessable error message in FIG. 80. In step 82, it transmits to the MCP 12 via the interface 36.

Then, the process jumps to FIG. 52, inputs a message transmitted through the interface 36, and repeats the above procedure to execute code conversion according to a control command.

As described above, the present invention codes and transmits character data of text received from a personal computer, not facsimile code data, to facsimile code data (image data), and converts the facsimile code to a facsimile code desired by the facsimile subscriber. There is an advantage of being able to transmit and receive between different heterogeneity models.
