Abstract

PURPOSE:To easily recognize missing of a page and to facilitate the management of a reception document by receiving a picture of plural pages and sending a message representing the presence of missing page after the transfer of picture when a picture of part of pages is missing. CONSTITUTION:When NSS signal information is sent from a sender to a facsimile equipment, a scanner 1 reads the information to extract RTI information and it is stored tentatively in a picture memory 4. A controller 6 discriminates the operating mode and when the mode is the normal mode, a coding decoding section 3 reproduces a sent picture and a plotter 2 records the picture on recording paper. In the case of the transfer mode, the received picture is stored in a memory 4. When the reception is finished, a management table representing the storage position is generated. When a missing page exists in the received picture, after the picture is transferred, a message representing the presence of a missing page is sent.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a transfer function for once storing received images and then transmitting them to another destination.

0002

[Background Art] A facsimile machine is often equipped with a forwarding function in which the telephone number of the forwarding destination facsimile device is registered in advance and the forwarding mode is set so that the received images are temporarily stored and sent to the registered forwarding destination. Are known. Here, for convenience, a facsimile station in which a facsimile machine set to such a transfer mode is installed will be referred to as a relay station.

[0003] By the way, when such a relay station receives multiple pages of images from a transmission source, some pages may be lost due to a transmission error, and only the correctly received pages may be relayed to the transfer destination. .

[0004] In this case, the destination facsimile machine runs out of pages for the received image, but if no transmission error occurs during image reception, the destination facsimile machine determines that the reception is normal and displays an error message. Don't do it.

[0005] For this reason, the operator at the transfer destination may not be aware of the lack of received images.

On the other hand, when a facsimile machine transmits an image, a TTI (transmitter) is placed at the leading edge of the transmitted image.
Terminal Identification
n) The date and time and the name of the sender are added as information. Also, by the transmission control procedure signal, R
TI (Remote Terminal Iden)
The name of the sender is notified to the receiving side as information (specification). RTI information is
This information is displayed on the receiving side during communication, and is used to display the sender in a communication management report showing the communication history.

Conventionally, when a relay station transfers an image, TT
As for the I information, the TTI information added to the received image was transmitted as is without adding that of the relay station. Furthermore, when receiving an image, the RTI information of the sender is stored, and the stored RTI information is sent to the transfer destination.

[0008] As a result, at the transfer destination, the TT of the received image
The name of the actual sender was recorded in the corresponding reception item of the I information and communication management report.

[0009] By the way, a communication management report usually includes the following information:
The communication date and time are recorded along with the received items. However, conventionally, the communication time on this communication management report and the time recorded in the TTI information of the received image did not match. In other words, in the communication management report, the reception time from the relay station is recorded as the communication time, whereas the TT of the received image is recorded as the communication time.
The I information recorded the sending time of the sender.

0010

[Problems to be Solved by the Invention] As described above, conventionally, if some pages are missing when transmitting from a source to a relay station, the operator at the destination does not notice the missing image. In addition, at the transfer destination, the TTI information of the received image and the time of the communication management report do not match, so there is a problem that the operator cannot easily manage the received document.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile machine which solves the above-mentioned problems and makes it possible to easily detect missing pages at a forwarding destination and to facilitate the management of received documents.

0012

[Means for Solving the Problem] To this end, one of the inventions of the present application provides that when images of a plurality of pages are received and images of some pages are lost due to a transmission error, images of correctly received pages are In addition to forwarding only the image to another destination, a message document indicating that there is a missing page in the image is sent.

[0013] Another invention is that when a received image is sent to another destination, if the sending time of the sender is added to the image, the sending time is changed to the time at that time. I am trying to correct it and send it.

[0014]

According to the above aspect of the invention, the transfer destination operator can easily know from the report document that there is a missing page in the received image.

According to another aspect of the present invention, since the time of the TTI information added to the received image and the time of the communication management report match, the operator can easily manage documents.

[0016]

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

FIG. 1 shows a block diagram of a facsimile machine according to an embodiment of the present invention. In the figure, a scanner 1 reads an original image and extracts image information, and a plotter 2 records the image on recording paper. The encoding/decoding unit 3 compresses the image information to be transmitted by encoding it using a known encoding method such as the MH method, and decodes the received image information to reproduce the original image information. The image memory 4 temporarily stores image information.

The modem 5 modulates and demodulates image information and transmits the same, and also transmits and receives various procedure signals for transmission control. The network control device 6 is connected to a telephone line and performs predetermined line control when making and receiving calls. The operation display section 7 displays the operating status of the device and is used by the operator to perform various operations.

The system memory 8 temporarily stores various information necessary for communication operations. The system control section 9 is a microcomputer that controls each of the above sections, and the system bus 10 is a signal line through which the above sections exchange various control signals and data with each other.

With the above configuration, it is assumed that the facsimile apparatus of this embodiment has the above-mentioned transfer function.

When this facsimile machine is powered on, it constantly monitors incoming calls as shown in FIG. 2 (N loop of process 101). Assuming that a call is received from the sender (Y in process 101), a known transmission control procedure is executed with the other party. At this time, the transmission source transmits RTI information using an NSS signal. The facsimile machine then extracts and stores the RTI information from the NSS signal (
Process 102).

[0022] Then, the operation mode is determined (processing 10
3). In this embodiment, it is assumed that the operation modes include a normal mode and a transfer mode.

Here, if the normal mode is set (N in process 103), the transmitted image is received and recorded and output on recording paper (process 104).

On the other hand, if the transfer mode is set (
Step 103: Y), the transmitted image is received and stored in the image memory 4.

In this embodiment, when images of a plurality of pages are received, the sending side is notified of the reception result of normal reception or reception error for each page according to a known procedure. Further, in the case of a reception error, the image information of that page is invalidated and not stored in the image memory 4, and the next page continues to be received.

[0026] In this way, only images of normally received pages are stored in the image memory 4 (process 105). When this image reception is completed, as shown in FIG. 3, a management table T is created that shows the reception result of each page and the storage position of image information of each page in the image memory 4 (process 106).
.

[0027] Next, the reception result is determined (process 107).
For example, as shown in FIG. 3(a), if there are errors on the second and fourth pages (Y in process 107),
After that, the incoming call is monitored for a certain period of time (Process 108, Process 109 from N in Process 108, Process 1 from N in Process 109)
to 08).

By the way, at the sending source, if an error occurs during transmission, the facsimile machine displays an error page, for example, as a transmission result report. In this case, the operator resubmits the error page.

When the facsimile machine of the relay station receives an incoming call while it is on standby (Y in process 108), it responds and uses the RTI information received at that time to determine whether or not it is the same as the other party from which the image was previously received (process 110). ).

[0030] Now, if it is a retransmission from the sender, it means that it is to the same destination. In this case (processing 11
0 Y), the transmitted image is received and stored in the image memory 4. In the present example, the images of the second and fourth pages will now be retransmitted. At this time, Fig. 3(b)
As shown in FIG. 3, each received page is made to correspond to each page that resulted in an error in the previous reception (process 111).

When this reception is completed, it is determined whether or not there is a transfer error (process 112), and if there is no error (Y in process 112), the communication is terminated.

Thereafter, a call is made to a preset forwarding destination telephone number (process 113). When the other party responds, known transmission control procedures are executed. At this time, as shown in FIG. 4(a), the RTI information received from the transmission source and stored is transmitted as is to the transfer destination as an NSS signal (process 11
4).

[0033] As a result, the RTI information is displayed on the destination facsimile machine.

By the way, in this embodiment, as shown in FIG. 4(b), the accumulated received images include the date and time of transmission a, the name of the sender b, and the number of pages c of the image at the sender. It is assumed that this information is added as TTI information.

[0035] This facsimile device corrects the date and time a in the TTI information of the received image to the current date and time (processing 115). Then, the corrected image is transmitted (process 116).

[0036] As a result, the transmitted image is recorded and output at the destination facsimile machine. On the other hand, if a call arrives from a source other than the sender while on standby, the communication is immediately stopped after responding (from N in process 1110 to process 109).

[0037] Furthermore, if there is no call from the sender during the standby period and a certain period of time has passed (Y in process 109), a call is made to the forwarding destination in the same manner as above, and the RTI information and time are corrected and accumulated. Send the image (processes 117 to 120). After this, an error report notifying that the page is missing is transmitted (process 121).

FIG. 5 shows an example of an image of this error report. That is, the title d is the name of the report, and the message e is a notice of missing images or other notifications. Date f and time g are the date and time of transmission from the relay station, and transmission source h is transmission source RTI information. Error page i indicates the page number that could not be transferred.

As described above, in this embodiment, when a page of a received image is missing, it waits for it to be retransmitted for a certain period of time, and when it is retransmitted, it is combined with the previously received image. I'm trying to send it to. This can reduce the frequency of transferring images with missing pages.

Furthermore, if the missing page is not retransmitted, a report document to that effect is sent after the image is transferred, so the transfer destination operator can easily know that there is a missing page.

[0041] Also, when transferring images, the RTI of the sender is
In addition to transmitting the information to the forwarding destination, the date and time of the TTI information is corrected to the transmission time.

For example, in the example shown in FIG. 4, assume that a communication management report is recorded and output at the transfer destination. Generally, in each communication item of a communication management report, the actual date and time of communication and RTI information received in that communication are recorded.

[0043] Therefore, in this case, in the communication management report, the date and time when the image was received from the relay station and the name of the sender are recorded in the corresponding reception item, as shown in FIG. Become. As a result, the recorded contents and the T of the received image are
The content of the TI information will now match, making it easier for the operator to manage documents.

[0044] In the above embodiment, a case has been described in which a facsimile machine that has entered a forwarding destination in advance and is set in forwarding mode becomes a relay station, but when it becomes a relay station due to a relay transmission command from another facsimile machine. Even in
The invention can be similarly applied.

[0044]

[Effects of the Invention] As described above, according to one of the inventions of the present application, when images of multiple pages are received and images of some pages are missing, after the image is transferred, a message indicating that there are missing pages can be sent. Since the message document is sent, the forwarding destination operator can easily know that there is a missing page in the received image.

[0045] According to another invention, when a received image is sent to another destination, the transmission time added to the image is corrected to the time at that time. At the transfer destination, the time of the received image matches the time of the communication management report, making it easier for the operator to manage the document.
