本発明はファクシミリ通信方式に関し、特に画信号伝送
管理上の通信方式に関する。Detailed Description of the Invention 8. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a facsimile communication system, and particularly to a communication system for image signal transmission management.
（従来の技術）

る。(Prior Art) Conventionally, in this type of facsimile communication system, the image signal transmitting station side not only indicates the end of one page of the image signal, but also sends a multi-page signal indicating that the image signal is to be retransmitted. It is sent out following the above image signal. On the other hand, if the confirmation signal from the image signal receiving station cannot be received for some reason, the image signal transmitting station transmits this multi-page signal again.
この場合、従米万式によれば多ページ信号の送信が再送
であろうとなかろうと、同一の信号を使用していた。In this case, according to Jubei Banshiki, the same signal was used whether the multi-page signal was being retransmitted or not.

を送出している。Therefore, as shown in Figure 3, even if the transmitting station cannot receive the confirmation signal from the receiving station due to an error,
As shown in FIG. 4, even if the receiving station cannot receive the image signal sent by the transmitting station, the transmitting station actually sends out page 01 of the image signal as shown in FIG. In Figure 4, two pages are sent out.
これにもかかわらず、受傷局側ではどちらの場合も画信
号’ｔ−１ページ分だけ受信したことしか認識できない
。Despite this, in either case, the affected station can only recognize that it has received only the image signal 't-1 page.

識別子が置かれていなかつ几。(The point that the invention is trying to solve) In the above-mentioned US facsimile communication system, when a multi-page signal is sent after a picture signal, a confirmation signal for the multi-page signal cannot be received and the multi-page signal is retransmitted. An identifier is not placed to indicate whether the image signal is a digital image signal, or whether it is a digital image signal that is sent out for the first time after the image signal.
このｔめ、上述し九ような理由で送受信が満足に行われ
なかつｔ場合には、受信側では画信号を１ページ分だけ
受信しｔことしか認識できないと云う欠点があつ九。Third, if the transmission and reception are not performed satisfactorily for the reasons mentioned above, the receiving side has the disadvantage that it can only recognize one page of image signals.

ミリ通信方式を提供することにある。An object of the present invention is to provide a multi-page signal, which is a procedure signal to be transmitted immediately after this image signal, at a transmitting station, every time an image signal of 1 p.-9 minutes is transmitted. The signal is sent with additional information indicating the page number of the image signal, and the receiving station side recognizes that the terminal received it as 9 (the number of pages of the image signal and the transmitting station side) The above disadvantages can be eliminated by comparing the attached information of the multi-page signal and determining whether there is a difference in recognition of the number of pages of the image signal transferred between the transmitting station and the receiving station. The object of the present invention is to provide a facsimile communication system configured to recognize the number of transmitted pages.
