Abstract

PURPOSE:To simultaneously output picture data received from the same transmission source even when communication is interrupted by recording the picture data received before interruption together with transmission source information when the communication is interrupted, and simultaneously outputting these data when the picture data are received after the communication is started again. CONSTITUTION:This system is composed of a network control part 1, MODEM 2, communication control part 3, picture memory 4, restorage part 5, output part 6 and control part 7. When the communication is interrupted by generating communication error or the like, the picture data received up to the moment are held and recorded in the picture memory 4 together with the transmission source information, and a communication line is connected again so as to execute communication. When this communication is normally completed and the transmission source information of the received picture data is coincident with the transmission source information of the picture data already held and recorded in the picture memory 4, the held picture data and the picture data received and recorded later are continuously outputted. Thus, even when the communication is interrupted, the picture data received from the same transmission source can be simultaneously outputted.

Description

[Detailed Description of the Invention] [Summary] Regarding the facsimile recording control method, especially the method for controlling the output of received images, even if there is a communication interruption, the image data received from the same source information is It is designed to be output all at once, and is equipped with an image memory that records the received image data together with its source information.If communication is terminated due to a communication failure during reception, the image data received up to the end of the communication will be saved. is retained and recorded in the image memory without being output, and when the source information of the image data received and recorded after that matches the source information of the image data already stored and the communication is completed normally, The image data held in the image memory and the image data received and recorded thereafter are configured to be outputted successively.

[Industrial application field]

The present invention relates to a facsimile recording control system.

In recent years, as facsimile communication has become more widespread and the number of subscribers has increased, the amount of data being sent and received has also increased rapidly. Therefore, in order to further increase the usefulness of facsimile communication, it is necessary to manage data received from a large number of different sender information in a manner that makes it easy to use.

[Conventional technology]

In conventional facsimile communication, when transmitting and receiving image data, approximately the following steps are taken.

First, the transmitting side sends a signal to the receiving side to inquire whether connection is possible. On the receiving side, if connection is possible, information regarding receiving capabilities such as functions of the receiving device is returned. In response to this, the sending side sends information about the image data scheduled to be sent, such as information such as page size.

After going through the above steps, the transmitting side compresses the image data and starts transmitting it. The receiving side receives the image data sent from the transmitting side and temporarily records the received image data in an image memory until the communication is normally completed (storage type facsimile device). After the communication is completed, the image data recorded in the image memory up to that point is read out and restored, and then outputted in the form of a document.

Furthermore, if a communication error occurs due to line noise or the like during reception and image data cannot be received accurately, that is, if a communication failure occurs, a communication abnormality signal is sent from the receiving side. When the transmitting side receives this signal, it terminates the communication even if untransmitted image data remains. Then, on the receiving side, the image data previously recorded in the image memory is read out and output in the form of a document.

[Problems to be Solved by the Invention] As described above, conventionally, even if communication ends midway through reception without receiving all of the scheduled data due to a communication error, the previously received data was outputting. Then, when the cause of the communication error is resolved and image data is received through communication again, the received data is recorded in the image memory and output, regardless of the previous communication. Therefore, when communication is interrupted, image data is output separately into data before the communication is interrupted and image data after the communication is interrupted. In particular, if there is an interruption in communication from another source after communication ends due to a communication failure, image data from another unrelated source may be generated between the data before and after the communication interruption. There was a problem in that data management became difficult.

Therefore, an object of the present invention is to output messages from the same sender all at once even when communication is interrupted.

[Means to solve the problem]

The solution to the above problem is to provide an image memory that records the received image data together with its source information, and when communication is terminated due to a communication failure during reception, the image data received until the end of the communication is output. When the source information of the image data that is received and recorded after that matches the source information of the image data that is already stored and the communication is completed normally, the image data is stored in the image memory. This is achieved by a facsimile recording control system that is characterized by sequentially outputting the image data held in the previous image data and the image data received and recorded thereafter.

[For production]

In the present invention, when communication is interrupted due to the occurrence of a communication error or the like, the image data received so far is retained and recorded in the image memory together with the source information. Then, the communication line is connected again and communication is performed. If this communication is completed normally and the source information of the received image data matches the source information of the image data already stored and recorded in the image memory, then the stored image data and the subsequently received and recorded Continuously output image data. If the communication is interrupted again even though communication has been started again, or if the sender information does not match, the information is retained and recorded in the image memory in the same way as described above in preparation for the start of the next communication.

As described above, even if communication is interrupted during reception, the image data received from the same source information will be output together and will not be separated.

Hereinafter, an embodiment of the present invention will be described along the flowchart shown in FIG. 4 while referring to FIGS. 1 to 3.

First, after the receiving device and the transmitting device are connected by a call from the transmitting device, the transmitting device notifies the sender of caller information. It was sent to me at this time! The sender information Ai on the sending side is recorded in the sender information recording area 4a of the image memory 4 as shown in the diagram (step 1). The subsequently sent image data Bi is sequentially sent to the image memory 4 via the NCU1, modem 2, and communication control section 3 according to the normal data processing process, and is recorded in the image data recording area 4b (step 2). . As shown in FIG. 2, the address of the image data Bi is the sender information A.
i is recorded in the sender information recording area 4a.

The receiving device continues receiving until the end of the communication while checking for any communication errors caused by line noise or the like (step 3). Then, it is checked whether the communication has ended normally (step 4). If a communication error occurs due to line noise, etc., and the communication ends without receiving the scheduled image data, the image data Bi received up to that point will be
It is held in the image data recording area 4b.

In this embodiment, it is assumed that the image data recording area 4b contains data that has been recorded and held without being output in this way during previous communication.

When the communication ends normally by receiving all the scheduled data, it is checked whether the image data Bj having the same sender information as the sender information Ai is recorded in the image data recording area 4b (step 5). This is the third
This is done using the detection circuit shown in the figure.

First, the counter 11 is started and the source information AI at address 0 of the source information recording area 4a shown in FIG. 2 is input to the comparator 12. Further, the source information Ai is input to the comparator 12. If the source information A1 and Ai do not match, the comparator 12 sends “1” and inputs it to the NOT circuit 13 to close the gate 14, so that the image data B1 at address 0 in the source information recording area 4a is The address is not sent to the image data recording area 4b, and the image data B1 is not output.In addition, the output "1°" of the comparator 12 at this time is sent to the counter 11, and the output of the comparator 12 at this time is sent to the source information recording area 4a Advance the address by one. Then, in the comparator 12, A
Compare 2 and At. Repeat the above process and get A
If there is no source information that matches i, only the image data Bi is sent to the output unit 6 via the restoration unit 5 and output (step 6). When there is matching source information Aj, "0" is sent from the comparator 12, inputted to the NOT circuit 13, the gate 14 is opened, and the image data B corresponding to Aj is sent.
The address of j is sent to the image data recording area 4b. Then, the image data Bj is transferred from the image data recording area 4b to the restoring unit 5.
The image data Bi is then sent to the output unit 6 and output (step 7), and then the image data Bi is output (step 8).

〔Effect of the invention〕

As described above, according to the present invention, even if communication is interrupted, the image data received before the interruption is recorded together with the source information, so the cause of the interruption is resolved, communication is resumed, and the image data is transferred. When receiving data, the data before interruption and the data after interruption can be output together.
Data from the same source information is not output separately. Therefore, it is useful for managing received image data.
