This information serves as reference information for expansion, expansion, etc. by the compression/expansion section 5 and the reduction/enlargement section 13.

In this embodiment, since the reference information is referenced by each ID, reference can be made regardless of movement of the storage area of each block.

The composite document data 25 having such a structure is
A standard transmission order is defined by the recommendation of T.T. Fourth
The figure shows the standard transmission order in the configuration of FIG. 3. In other words,
The order is composite document data 25 - page data 27 - character block data 29 -> text data 32 - image block data 33 - image data 36. Furthermore, in this case, each reference information may be omitted.

However, it is unlikely that all received data follows this order. In this case, it is possible to change the order if reference information is added, but the standard transmission order is always the most efficient for combining and reproducing processing on the receiving device side.

Therefore, as in this embodiment, the communication section 8 performs the following processing. FIG. 5 is a flowchart showing the processing procedure in the communication section 8. Here, the reception process of the communication unit 8 when receiving a composite document including image data and character data is shown. This program is stored in ROM18,
The process starts when the communication unit 8 receives data from the line 16 and outputs a reception processing request to the MPU 17 .

In step S1, data received from the line section 20 is received, and in step S2, the received data is stored in the communication buffer 22 using the DMAC 19. The received data is analyzed in step S3, and it is determined in step S4 whether it is an end command. Note that the determination as to whether or not the data has ended may be made based on the number of blocks in the control information, or may be determined based on whether or not the next page of data comes.

If it is a termination command, the reception process is terminated. If it is not an end command, the process proceeds to step s5, where it is determined from the control information whether the transmission order is the standard order, and if it is the standard order, the received data is sent to the main side via the interface section 23 in step S6. Transfer in the same order. Then, the process returns to step S1 to process the next received data. Note that the transmission order is not determined based on the information in the control information, but in the case of the standard order, the block reference information is omitted. It can also be determined based on the presence or absence of block reference information.

It is also possible to check each ID in turn.

If it is not the standard transmission order in step S5,
In step S7, this received data is transferred to the communication buffer 2.
2, and in step S8 it is determined whether all the data necessary to rearrange the transmission order into the standard order has been received. If all the data is not yet received, the process returns to step S1 and the next reception is performed. Process data. If the necessary received data is complete, the data is rearranged in the standard order in the communication buffer 22 in step S9, and the data is transferred to the main side via the interface section 23 using the DMAC 19 in step SIO. Then, the process returns to step Sl to process the next received data.

FIG. 6 shows a more detailed flowchart showing the rearrangement of received data in step S9. First, step S90
The received data are sequentially searched in step S91, and synthetic document data is searched for. When the composite document data is found, the composite document data is sent to the main side in step S92, the page data is found from the page reference information of the composite document data in step S93, and the page data is sent to the main side in step S94. In step S95, block data is found from the block reference information of the page data, and in step S96
Check the type of block data found in , and if it is a character, proceed to step S97 and send the character type block data to the main side, find the text data from the text reference information of the block data in step S98, and send it to the main side in step S99. send to the side

Thereafter, in steps 5100-S104, image type block data and image data are found and sent to the main side in order. In this way, the main side can always receive data in the standard transmission order shown in FIG.

In this embodiment, the communication unit focuses only on the transmission order and rearranges the data, but it also checks the consistency of the reference information and ID and determines the validity of the data during data reception. It is also possible. Also, in the case of standard transmission order, reference information may not be added, but by temporarily storing this data and adding reference information in the communication section, it is possible to reduce the processing in the main unit. It is.

As explained above, by rearranging the received data in the communication unit to make the transmission order constant, it is possible to speed up the output processing of the received document to the CRT or output device, and the processing speed is increased. It is distributed between the main and communication parts, allowing efficient data communication.

[Effects of the Invention] According to the present invention, it is possible to provide a general-purpose document processing device that efficiently processes and outputs received document information consisting of image information and character information.
