If the result of judgment 103 is YES, processing 1 is performed to receive the image information for the first page PIXI.
04), the received image information PIXI is decoded into the original two signals by the encoder/decoder 7 and transferred to the plotter 5 to be recorded and outputted 105), and this process is repeated until the end of the page (judgment 106). NO loop), thereby recording and outputting the received image of the first page.

Furthermore, regarding the image information PIX2 to PIX+o from the second page onward, the process 107) for receiving the image information and the process 108) for storing the received image information in the image memory 8 are repeated until the page ends (judgment 109). (NO loop), this page reception process is repeated until all pages have been received (determination 110).

Then, when receiving the image information for all pages and receiving the procedure end signal EOP, the line is restored (process 111).
.

Further, when the result of determination 103 is NO, normal reception processing (process 112) is executed, and the process moves to process 111 to restore the line.

As described above, in this embodiment, when receiving confidential data, the image of the PIXI image information on the first page is recorded and output, so by placing the above-mentioned cover letter on this first page, confidential transmission is possible. It is now possible to clearly indicate what has been done and its destination, and the operator of the receiving device can quickly retrieve images during confidential reception.

In the embodiment described above, the received image of the first page is recorded and outputted at the same time as it is received, but the received image of the first page is recorded and outputted after receiving the received image information of all pages. You can also do this.

Next, a case will be described in which this facsimile machine sends S-transmission to any destination.

In this case, the operator on the sending side sets the cover letter as described above as the first page of the original to be sent, sets the original to be sent in this state on the scanner 4, inputs the destination information, and uses the confidential transmission function. When you perform the necessary operations to start image information transmission when selecting
The transmitting device TX calls the specified receive@tilRX.

As a result, as shown in FIG. 4, the receiving device RX responds with a called station identification signal CED indicating that the own terminal is a non-voice terminal, and also sends a called station identification signal CED that indicates that the own terminal is a non-voice terminal. Digital identification signal DI for notifying functions

Respond to X.

When the transmitting device TX receives these identification signals, it transmits a non-standard function setting signal NSS to notify the transmission function to be used at that time, and then performs modem training at the transmission speed set at that time. The training check signal TCP is sent to the

If the reception result of the training check signal TCP is good, the receiving device RX responds with a reception preparation confirmation signal CFR.

The transmitter TX operates a scanner to read the image of the cover letter on the first page, encodes and compresses the image in the encoder/decoder 7 using the encoding method set at that time, and
The image information 1) IXI thus formed is transmitted, and when the transmission is completed, a message end signal EOM is sent out in order to change the transmission function used when transmitting the image information from the second page onwards.

When the receiving device RX receives the image information PIXI of the first page, it decodes the image information PIXI into the original image (i) and then records and outputs it from the plotter. If the result is good, it responds with a message confirmation signal MCF to the transmitter TX.Also, at this time, since the message end signal EOM has been received,
Move to phase B.

When the transmitting device TX receives the message confirmation signal MCF, it sends out a non-standard function setting signal NSS (confidential) that includes an indication that confidential transmission is to be used and password information, and notifies the transmission function to be used at that time. After that, a training check signal TCP is sent out to perform modem training at the transmission rate set at that time.

If the reception result of the training check signal TCP is good, the receiving device RX responds with a reception preparation confirmation signal CFR.

From then on, as in normal confidential transmission, the transmitting device TX sequentially transmits the image information PIX2 to PIXm of the second and subsequent pages formed in the same manner as the image information PIXI of the first page to the receiving device RX. At the same time, when the transmission of the image information PIX(, -□) from the second page to the last page before the final page is finished, a multi-page signal MPS is sent, and when the transmission of the image information MXm of the final page is finished, a procedure end signal is sent. Send EOP.

The receiving device RX receives image information PIX2 to PIX2 from the second page onwards.
When IXrrr is received, the image information PIX2 to P I
While storing X m in the image memory, it is transferred to the encoding/decoding unit to judge the reception result, and when the reception of each page is completed, if the reception result is good, it responds with a message confirmation signal MCF. .

When the transmitter TX finishes transmitting the image information PIXm of the final page and finishes transmitting the procedure end signal EOP, it transmits a disconnection command signal DCN to restore the line.

Further, upon receiving the disconnection command signal DCN, the receiving device RX restores one line.

When the confidential reception is finished in this way, the receiving device RX
As in the conventional device, the image information that has been confidentially received is extracted.

FIG. 5 shows a processing example of the transmitter TX in this case.

When preparations for transmission are completed and a command to start transmission is issued, a call is made to the transmission destination specified at that time, and then it is first checked whether the transmission at that time is confidential transmission (decision 20).
1).

When the result of the judgment 201 is YES, a pre-transmission procedure (process 202) and a training procedure (process 203) similar to the normal transmission operation are executed, and when the image information transmission stage is reached, the first page is scanned by the scanner 4. reads the transmitted original, transfers the resulting image signal to the encoding/decoding section 7, encodes and compresses it using the encoding method set at that time, and transmits the resulting image information to the modem 9. and send it to the receiving device RX (204).
The process continues until the reading of one page is completed (No loop of judgment 205).

When the transmission of the image information PIXI of the first page is finished, the message end signal EOM is sent out (206), and when the response signal from the receiving device RX is received, the non-standard function setting signal (confidential) NSS mentioned above is sent out. (Process 207)
.

The training procedure is performed again (process 208).

From this point on, like the image information PIX 1 on the first page,
While transmitting the image information PIX2 to PIXm from the second page onward (No loop of process 209 and judgment 210), 1
When the transmission of the image information for one page is completed, it is determined that the multi-page signal MPS should not be transmitted for any page other than the last page (211);
Process 212), in the case of the last page, a procedure end signal EO
P is sent out (process 213).

When the process 213 is completed, a process 214) for receiving a response signal from the receiving device RX, a process 215) for transmitting a disconnection command signal DCN upon receiving the response signal, and a process 215) for restoring the line (process 216). end.

Also, if confidential transmission is not set, judgment 201
When the result is No, normal transmission processing (processing 21
7) is executed and the process moves to process 216.

In this way, during confidential transmission, the image information of the first page is transmitted in the normal state, and the image information of the second and subsequent pages is transmitted using the confidential transmission function. The image of the cover letter is recorded and output by the receiving device RX, and the image information on the second and subsequent pages is not recorded and output.

Therefore, the operator of the receiving device RX can know that there has been a confidential reception, the confidential destination, etc., and can quickly take action on the confidential reception image.

By the way, as explained above, confidential transmission (hereinafter referred to as optional confidential transmission) in which only the first page of the received document is recorded and output and the received images from the second page onward are stored.
It is also possible to selectively use either conventional confidential transmission.

In this case, by operating the operation display section 6 of the facsimile machine, the setting whether or not to use the optional confidential transmission is made in advance.

At the start of transmission, if confidential transmission is set, it is checked whether optional confidential transmission is set, and if it is set, the non-standard function setting signal NSS is sent to the receiving device in the pre-transmission procedure. , optional confidential transmission information, and password information. Further, if the option confidential transmission is not set, normal confidential transmission is performed, and therefore the non-standard function setting signal NSS includes information indicating that normal confidential transmission is not performed and password information.

In this state, the transmitting device Tx performs the same procedure as in FIG. 2 to transmit image information.

On the other hand, the receiving device RX executes the process shown in FIG. 6 to receive image information.

That is, first, a predetermined pre-transmission procedure (process 301) and a training procedure (process 302) are executed, and it is checked whether the option confidential transmission or confidential transmission is specified in the pre-transmission procedure (determinations 303 and 304). .

If the result of judgment 303 is YES, processing 3 is performed to ensure that the image information is not received for the image information PIXI on the first page.
05), the received image information PIXI is decoded into the original image signal by the encoder/decoder 7 and transferred to the plotter 5 to be recorded and outputted (306), and this process is repeated until the end of the page (decision 307). NO loop), thereby recording and outputting the received image of the first page.

In addition, the image information from the second page onward PIX2 to PIX
For m, process 308) to receive the image information, process 309) to store the received image information in the image memory 8, and repeat this process until the end of the page (NO loop of judgment 310), completing the reception of all pages. This page reception process is repeated until the page is received (determination 311).

Then, when the reception of the image information of all pages is completed and the procedure end signal EOP is received (the result of judgment 311 is YES), the line is restored (process 312).

Further, if normal confidential transmission is set instead of optional confidential transmission and the result of determination 304 is YES, the process moves to process 308 and image information of all pages is accumulated.

Also, confidential transmission is not set and the result of judgment 304 is NO.
When this happens, normal reception processing (process 313) is executed, and the process moves to process 312 to restore the line.

In this manner, when the optional confidential transmission is set, the received image of the first page is recorded and output by the receiving device RX, and the received images of the second and subsequent pages are stored in the image memory 8.

Furthermore, when normal confidential transmission is set, all received images are stored in the image memory 8. Furthermore, when confidential transmission is not set, a normal image information receiving operation is performed and all received images are recorded and output.

In addition, in the embodiment described above, at the time of optional confidential transmission,
When the receiving device RX receives the image information of the first page, it records and outputs the contents of the image information, but after finishing receiving the image information of all pages, it records and outputs the contents of the image information of the first page. You can also do this.

[Effects of the Invention] As explained above, according to the present invention, in the case of N-extension transmission, the image information of the first page is recorded and output, and the image information of the second and subsequent pages is accumulated without being recorded and output. Therefore, when a confidential reception is received, for example, an image of a contact manuscript in which a confidential address and the like are recorded is recorded and output, so that it is possible to surely know that there has been a confidential reception.
