It is determined that this is a report.

FIG. 3 is a diagram for explaining the flow of a normal transmission protocol according to the present embodiment. The protocol in this embodiment is described as G4 facsimile in the CCITT recommendation.

First, the MPU 1 requests the CCU 7 to make a call and establish a connection below the transport. When a link below the transport is established, a protocol start command (hereinafter referred to as "CSS") is transmitted in protocol 1 (P1), and a session start acknowledgment (hereinafter referred to as "RSSP") is received in protocol 2 (P2). I do.
In the protocol 3 (P3), a document function list command (hereinafter, referred to as “CDCL”) is transmitted, and in the protocol 4 (P4), a document function list acknowledgment (hereinafter, referred to as “RDCLP”) is received.

In the protocol 5 (P5), a document start command (hereinafter referred to as "CDS") is transmitted. In the protocol 6 (P6), the data of the first page is transmitted, and when the transmission of all data is completed, in the protocol 7 (P7), a document page boundary command (hereinafter, CDPB is transmitted, and when the communication is executed normally). , Protocol 8 (P
At 8), a document page boundary acknowledgment (hereinafter, “RDPBP”) is received.

Similarly, from the second page onward, the protocol 9 (P9) to the protocol 12 (P12) are repeated, and when the transmission of the data of the final third page is completed, the protocol 13 (P13) issues a document end command ( Hereinafter, "CDE") is transmitted, and as a result of successful communication, a document end acknowledgment (hereinafter, referred to as "RDEP") is received in the protocol 14 (P14).

In the protocol 15 (P15), a session end command (hereinafter referred to as "CSE") is transmitted, and in the protocol 16 (P16), a session end acknowledgment is received. The MPU 1 issues a disconnection instruction of the transport or lower to the CCU 7, and the CCU 7 disconnects the transport or lower and ends the communication.

FIG. 4 is a view for explaining the flow of the transmission protocol when data transmission results in an error according to this embodiment.

From protocol 1 (P1), protocol 1
Up to 0 (P10) is as described above.

When an error occurs in the data communication of the second page, a document page boundary denial response (hereinafter referred to as "RDDPB") in protocol 20 (P20).
N ”).

The protocol 15 (P15), 16
At (P16), the session is cut.

FIGS. 5 and 6 are flowcharts for explaining the operation of controlling output of an error report, output of a stored document, and deletion of a stored document when a transmission error occurs.

In this control, the MPU 1 executes a program stored in the ROM 2 in advance.

In step S (S1), the CCU 7 is requested to make a connection below the transport. When the connection is established, in step 2 (S2), a session is set by the CSS / RSSP described above. In step 3 (S3), negotiation is performed by the above-described CDCL / PDCLP, and the result is used as an invocation to set a document by the CDS. In step 4 (S4), data of one page unit is transmitted. Step 5 (S
In step 5), when a PDPBN indicating an error is received as a response to the CDPB, the control is transferred to step 8 (S8). Upon receiving the RDPBP indicating normality, the process proceeds to step 6 (S6), and if there is next page data to be transmitted, the process returns to S4.

When the transmission of the last page is completed, step 7
Proceed to (S7), the document is terminated by CDE / RDEP, and in step 8 (S8), CSE / RS
Confirm the cutting of the session by EP. Step 9 (S
In 9), the CCU 7 is instructed to disconnect below the transport, and the transmission operation ends.

In S5, if any error is detected, in S8 and S9, the session and the transport are disconnected as described above, and the control is shifted to the local processing from step 10.

In step 10 (S10), it is determined whether a transmission error report has been output. If no report has been output, step 11 is skipped and control is transferred to step 12. If there is a report output, step 11 (S1
Proceeding to 1), a transmission error report is created in a format as shown in FIG. Here, the character code data on the report is created on the RAM 3. Next, the created character code is developed as font information composed of dots using the CGU 6 and output to the PRU 10 as an image.

In step 12 (S12), it is determined whether or not to output a stored document in which an error has occurred. If not, control is transferred to step 17 (S17). In step 13 (S13), the start page of the document to be output is set by key input from the console 9. The set contents are stored in the RAM 3. In the example of the protocol shown in FIG. 4, the start page means a page where an error has occurred, that is, a second page.

In step 14 (S14), it is determined whether to output all pages of the stored document or only pages after the error. If the page output after the error is sufficient, the process proceeds to step 16. In step 15 (S15), the output page is reset to the first page of the document.

At step 16 (S16), the stored document page is output to the PRU 10 according to the algorithm described above. When the output of all designated pages is completed, in step 17 (S17), DISCU is executed.
4 is estimated, and only when the available capacity exceeds a preset allowable amount, step 18 (S1) is executed.
8) to delete the stored document from DISCU4,
Free up memory.

FIG. 7 is a flowchart for explaining the operation of controlling the OCR input of the transmission error report and the re-calling according to the present embodiment.

In FIG. 3, when the original is set in the RDU 11 and the scan operation is performed, in step 20 (S20), the OCRU 5 determines whether or not the input original is the OCR sheet as shown in FIG. It is determined from the mark 23. If it is not an OCR sheet, the control shifts to a normal process. Step 21 (S2
In 1), it is determined whether or not the input OCR sheet is the report type number 24 for displaying the transmission error report, and if different, the control is shifted to other processing. Step 22 (S2
In 2), the OCRU 5 determines whether or not there is a stored document to the read destination.
If this is not the case, the process proceeds to step 23 (S23), and the following input document is read in blank.

If the stored document does not depend, step 24
In (S24), it is determined whether or not the input document further depends. If not, the control is shifted to error processing.

In step 25 (S25), the RDU 17 accumulates the transmission error document in page units, and in step 26 (S26), recalls and transmits to the destination determined by the OCRU 5.

As described above, according to this embodiment,
A transmission error document is output, and an error report for OCR input is output on the first page. The stored document is erased, and only the transmitted page is erased. This has the effect of providing an easy retransmission operation.
