Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 2B-7 The present invention relates to an image communication device equipped with an image memory capable of storing received image information before recording.

2. Description of the Related Art A conventional device of this type is shown in FIG.
a communication unit 1 that transmits and receives image information over a telephone line in accordance with the communication control procedure of the T Recommendation; an image memory 2 that can store at least a plurality of pages of transmitted image information or received image information; It has a reading section 3 that reads image information from a document, and a recording section 4 that prints and records the image information on recording paper.When receiving image information, the received image information is stored as one file for each communication as an image. After the image information is stored in the memory 2, the image information stored in the image memory 2 is read out file by file and printed and recorded in the order of received pages.

Problems to be Solved by the Invention However, according to such a configuration, if the reception of image information is temporarily interrupted due to a communication error, extra communication time is required, wasteful printing is performed on the receiving side, or the receiving side The problem described in 1.-01- arises for the following reasons.

Suna, 4cchi, multiple pages worth of image information can be sent via communication J-
If the sender is interrupted in the middle of a page due to an error, the sender can retransmit (
1) Retransmit all pages of image information from the first page, or (2) transmit only the remaining pages that could not be transmitted due to communication interruption.

In the case of (1) above, on the receiving side, the image information from the first page up to the page immediately before communication was interrupted, and the image information from the first page
Receive all image information from page to final page and each evening 1. and print it out.

Therefore, for the image information up to the page immediately before the communication is interrupted, the operations of receiving and printing the transcript are repeated. This duplication results in extra communication time and wasteful printing.

In this case, if the receiving side invalidates the received image information whose communication was interrupted due to an error in the image memory, it is possible to avoid unnecessary duplication in printing and recording operations. However, since the invalidated image information is also not received, extra communication time cannot be avoided.

On the other hand, in the case of (2) above, wasteful communication of image information of the same page should be avoided. However, the image information up to the middle page before the error occurred, and the remaining image information sent by re-communication after the error recovery and the repage image information are stored in the image memory as independent files, and then each file is Since the two documents are printed and recorded separately, the operator on the receiving side has to perform the troublesome work of organizing the two separately printed documents into one document by collating the destination and page. Also, there is no guarantee that the image information up to the middle page and the image information of the remaining pages will be received consecutively, and there is no guarantee that the image information up to the middle page and the image information of the remaining pages will be received continuously. In this case, the above-mentioned sorting work becomes even more complicated, and the burden on the operator increases significantly.

As a countermeasure for the above-mentioned problem, there is a facsimile storage and forwarding device described in, for example, Japanese Patent Application Laid-Open No. 63-87071. If the image information of multiple pages that should be communicated in one communication is divided in the middle of the page due to the occurrence of a communication error and the re-communication performed after the error has been recovered, the divided image information is After linking to image information for one communication, relay transmission is performed.

However, this facsimile storage and forwarding device can only be installed on a line dedicated to facsimile IJ, and cannot be applied to image communication devices that use a normal telephone network. "Communication that occurs" - vs. Ra
Although it is effective, it is not effective against communication errors that occur between the relay side and the receiving side, so it is not useful for solving the problems mentioned in 1.

6 ＼ - The present invention has been made in view of the above-mentioned problems, and even if the reception of image information is temporarily interrupted due to a communication error, it does not require extra communication time and eliminates unnecessary printing on the receiving side. To provide an image communication device capable of printing and recording received image information with the destination and page order clearly arranged without performing recording.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention stores received image information in the image memory as one file for each communication, while storing multiple pages of images to be received in one communication. When information is received divided at intermediate pages due to the occurrence of a communication error and recommunication performed after the error is recovered, each divided image information is concatenated into one file based on the respective collation information, and this concatenation is performed. This configuration prohibits printing and recording of divided image information before the split image is completed.

Effects of the present invention With the above-described configuration, the image information whose reception was interrupted at an intermediate page due to a communication error and the image information of the remaining pages received by retransmission after error recovery are transmitted to the receiving side. Since the images are concatenated into a single file and then printed and recorded, even if the reception of image information is temporarily interrupted due to a communication error, there is no need for extra communication time, and there is no need to waste print records on the receiving side. It becomes possible to print and record the received image information in a state where the destination, page order, etc. are clearly arranged without having to perform the above process.

Example Embodiments of the present invention will be described below based on the drawings.

Note that parts that are the same as or correspond to the conventional ones are indicated using common symbols.

FIG. 1 shows a schematic configuration of an image communication device according to an embodiment of the present invention, in which 1 is a communication unit that transmits and receives image information over a telephone line in accordance with the communication control procedure recommended by C0ITT; 2 is an image memory capable of storing at least a plurality of pages of transmitted image information or received image information; 3 is a reading section that reads image information from the original; 4 is a recording section that prints and records the image information on recording paper; and 5 is an image memory These are file editing means for concatenating received image information that has been received after being divided due to a communication error, and recording control means for prohibiting printing and recording of divided image information before the concatenation by the file editing means 6 is completed.

Here, the file editing means 5 and the recording control means 6 are
The general-purpose information processing device is a microcircuit-based general-purpose information processing device that is centrally configured with a main control section (not shown) that controls the entire device.

When multiple pages of image information to be received in one communication are received divided into intermediate pages due to the occurrence of a communication error and recommunication performed after recovery from the error, the file editing means 6 is configured to handle each divided page. File control is performed to concatenate the image information into one file based on the partner machine information obtained during each communication. This file control is mainly done by
F9 for managing the image information stored in the image memory 2. This is done by manipulating the file information (management information). File information is created one by one for image information for one communication, and stored in a management area using a part of the storage area of the image memory 2.

FIG. 2 shows an example of the above file information.

As shown in the figure, the file information 70 includes a sender ID (sender identification information) 71, a sender password 72,
The machine code (machine number unique to the device) 73, communication time 74, and normal received image information that has been received continuously without errors are sent by being inserted into the PIF (Facsimile Information Field). It is organized by identification information 76 indicating the current page number of image information, (serial page number) 76, total number of pages 77, page information 78 indicating the storage address (first address and last address) of each page of image information, etc. . Among these, a part or all of the sender ID 71, sender PIN 72, machine code 73, etc. is used as the other party's machine information for the file editing means 5 to perform the F10 forward-no-ail control. It looks like this.

Figure 3 shows 1. An example of the format of IJ-information is shown below.

As shown in the figure, the directory information 8o includes flag information 81 for managing the use or non-use of previously prepared file information (100 items for ages 1 to 00 in the illustrated example), and flag information 81 for each file. It is organized by vector information 82 indicating the location (address) of the information.

The operation of the image communication apparatus configured as described above will be described below.

FIG. 4 is an example of a communication operation procedure when multiple pages of image information that should be received in one communication is divided into intermediate pages due to the occurrence of a communication error and recommunication performed after recovery from the error. This is what is shown.

In FIGS. 1 to 4, a call is first made from the transmitting side, and then a CNG (calling tone) is sent out. After this, between the receiving side and the sending side, N5F
(non-standard identification signal), DIS (digital identification signal) and N
8S (non-standard function setting signal) and DO8 (digital command signal) are exchanged.

Through this exchange of signals, the receiver receives the sender's ID.
, obtain the other party's machine information such as the sender's PIN and machine code. Then, preparations for reception are performed, such as registering file information for storing image information to be received in the image memory 2.

When preparation for reception is completed, from the receiving side to the sending side (1, FR
(reception ready signal) is sent. The sending side that receives this cFR starts sending image information, which is actual information, from the first page. The receiving side receives the image information sent from the transmitting side and sequentially stores it in the image memory 2. This storage is performed while writing predetermined management items in the file information described in -.

When communication of image information for the first page is completed and there is image information to be communicated next, the sending side sends an MPS (multi-page signal) to notify the receiving side that there is a next page to send. . In response to this MPS, the receiving side
Send F. The transmitting side waits for this MCF to be returned and then starts transmitting the image information for the next second page.

Here, if a communication error occurs and the image information of the second page cannot be transmitted normally, the receiving side will not be able to transmit this MPS even if the transmitting side sends the MPS after the image information of the second page.
Do not send MCF for

The transmitting side determines that an error has occurred since the MCF is not returned from the receiving side, and sends a DON (line disconnection command) to temporarily terminate the communication.

In this way, if the communication of image information for multiple pages is interrupted at a page halfway due to an error, the receiving side can divide the image information into a file containing only the image information up to the page immediately before (the first page). Create an image information file. At this time, identification information indicating that the file information is not a normally received image information file should be added to the file information. In other words, the divided image information file is distinguished from the normally received image information file in which all pages are received normally and consecutively.
/\-7 Pay it. Further, this divided image information file is excluded from the print recording target by the recording control means 6, and the receiving operator is notified of this by display.

The sending side, which once terminated communication due to an error, waits for the error to recover, and then re-communicates to send the remaining pages that could not be sent due to the error. As in the case before the error, this re-communication includes the calling and sending of CNC from the sending side, the N5Ii' carried out between the sending and receiving sides, ■) the exchange between IS and N5SSDC8, and the sending of CNC from the receiving side. This should be done through the sending of FR. At this time, the sending side inserts a message indicating recommunication into the NSF's FTP and sends it. Then, transmission of the image information of the remaining pages (second and subsequent pages) that was interrupted due to the communication error is started.

The receiving side receives the image information of the remaining pages sent through recommunication while returning the MCF for each page. At this time, the received image information is stored using the existing file information registered at the time of the first communication before the error, without registering new file information. That is, sender ID γ1, sender password 7
2. By checking the other party's machine information such as machine code 73, the existing file information registered at the time of the first communication is searched, and by rewriting the content of the searched existing file information, it is possible to avoid errors caused by a communication error. The interrupted image information and the image information of the remaining pages sent by re-communication after error recovery are stored in image memory 2.
Perform concatenated editing processing as a file.

When the communication of image information for the final page (third page) is completed, the sending side sends an EOP (procedure end signal), in response to which the receiving side sends an MCF, and then the sending side sends a DCN. communication is terminated.

When the image information of the remaining pages (2nd and 3rd pages) is successfully received through re-communication, the image information file to which the image information of the remaining pages is linked can be printed by rewriting the discrimination information in the file information. It is converted into a normal received image information file 15'\/ which is to be recorded.

As described above, the image information whose reception was interrupted on the middle page due to a communication error and the image information of the remaining pages received by re-communication after error recovery are concatenated into one file on the receiving side. It will be printed and recorded. As a result, even if the reception of image information is temporarily interrupted due to a communication error, the received image information can be sent to the destination and page order without taking extra communication time and without unnecessary printing records on the receiving side. etc. can be printed and recorded in an easy-to-understand and organized manner.

In order to combine the image information that was received in parts due to a communication error into one file, verification is performed using information that combines part of the recipient machine information such as the sender ID 71, sender PIN 72, and machine code 73 with the communication time. It may also be done by

Effects of the Invention As is clear from the above explanation, the present invention allows received image information to be stored in the image memory as one file for each communication, while storing multiple pages of image information to be received in one communication. When a communication error occurs and re-communication is performed after the error is recovered, if a page is received divided at an intermediate page, each divided image information is concatenated into one file based on the respective collation information, and this concatenation is completed. By prohibiting the printing of divided image information before splitting, the image information whose reception was interrupted due to a communication error and the image information of the remaining pages received by retransmission after error recovery can be stored in one page on the receiving side. Printing is performed after being linked to a file, so even if the reception of image information is temporarily interrupted due to a communication error, there is no need for additional communication time, and unnecessary printing is performed on the receiving side. without any
This has the effect that the received image information can be printed and recorded with the destination and page order clearly arranged.
