The transmission data s is stored in time series with the destination information t. The transmission destination information control circuit 42 sequentially dials the telephone numbers of the transmission destinations stored in a fixed cycle, and when the transmission destinations can be normally connected, the connected transmission data w stored in the transmission data storage circuit 43 is transmitted. Is transmitted to reduce the transmission data that is incompletely transmitted, and the line is disconnected after the transmission of the transmission data w is completed.

Further, as a facsimile apparatus for performing a similar facsimile communication service via a comprehensive service digital network, as shown in Japanese Patent Laid-Open No. 3-99577, a transmission is performed in order to reduce transmission data that is incompletely transmitted as much as possible.

There is a point.

In the case of the one disclosed in Japanese Patent Laid-Open No. 3-99577, a facsimile machine connected to the integrated service digital network uses another channel to effectively use the memory and shorten the transmission waiting time. However, there is a problem that it cannot be applied to a facsimile device connected to a general telephone line, and at the same time, there is a problem that it cannot process a data communication request from another channel during transmission and reception.

An object of the present invention is to store data that could not be sent due to a line busy in the transmission data storage circuit, to transmit the data collectively when a transmission factor to the same destination occurs, and to enable the telephone exchange to operate. If you have a call waiting function, if there is a reception request from a third party during transmission, you will be notified of the waiting time, and if there is a reception request from a third party during reception, you will get the other party information and end reception Another object of the present invention is to provide a facsimile device capable of increasing the success rate of facsimile transmission by connecting to a destination later.

First, in step A1, the destination information bb input from the destination information input circuit 9 is written in the destination information buffer circuit 18. Then, in step A2, the transmission data c of the facsimile obtained by optically reading and converting the drawing drawn on the paper is written in the transmission buffer circuit 4. Subsequently, in step A3, the network control circuit 7 connects the line to the destination in the destination information buffer circuit 18. Next, in step A4, it is identified whether or not the line is busy. When the line is busy, the transmission data s is stored in the transmission data storage circuit 8 in step A5, and the transmission destination information buffer circuit is stored in step A6. The destination information jj of 18 is stored in the destination information storage circuit 20. If the result of the determination in step A4 is that the line is free, the header information x is transmitted in step A12, and the transmission data d of the transmission buffer circuit 4 is transmitted in step A13. When the determination result in step A4 is line busy and the destination information jj and the transmission data s are stored in the destination information storage circuit 20 and the transmission data storage circuit 8, after a predetermined time has elapsed in step A7, in step A8. The line is connected to the destination stored in the destination information storage circuit 20. Then, in step A9, it is again determined whether or not the line is busy. When the line is busy, the process returns to step A7 and waits for a certain period of time. If the result of determination in step A9 is that line connection is possible, the header information x is transmitted in step A10, and then the corresponding data in the transmission data storage circuit 8 is transmitted as transmission data rr in step A11.
During transmission in the above-mentioned step A11 and step A13,

The destination information aa is taken out. While receiving steps B1, B3, B4, step B
In step 5, it is always identified whether or not there is a connection request from a third party, and if a connection request from a third party occurs, step B6
Then, the third party's partner information ss is stored in the destination information storage circuit 20, and then the third party's line is disconnected in step B7. Subsequently, in step B8, it is identified whether or not the reception of the interrupted reception process is completed. If the reception is completed, after the reception process is completed, the reception destination of the destination information aa is stored in the transmission destination information storage circuit 20 in step B9. It is identified whether or not there is the same transmission destination as the above. If there is, the network control circuit 7 is set to the data transmission mode in step B10, the header information x is transmitted in step B11, and then the transmission data storage circuit 8 of the transmission data storage circuit 8 is transmitted in step B12. The corresponding data is transmitted as transmission data rr. After the transmission is completed,
In step B9 again, it is identified whether or not the destination information storage circuit 20 has the same destination as the destination of the destination information aa. If not, the destination information storage circuit 20 stores the destination information ss in step B13. It is identified whether or not there is the same transmission destination as the reception destination, and if the destination information ss is in the transmission destination information storage circuit 20, the reception processing is performed by connecting to the destination information ss in step B14, and step B13 is performed again. Then, it is discriminated whether or not the destination information ss is present in the destination information storage circuit, and if not, the processing is terminated. If it is determined in step B1 that there is no header information, the conventional receiving process is performed in step B2 and the process ends.

[0021]

As described above, according to the present invention, the data which could not be sent due to the line busy before is stored in the transmission data storage circuit and can be collectively transmitted when the transmission factor to the same destination occurs. In addition, if the telephone exchange uses a line with a call waiting function, if there is a reception request from a third party during transmission, the waiting time is notified and the reception request from the third party is received during reception. If so, there is an effect that it is possible to increase the success rate of facsimile transmission by obtaining the destination information and connecting to the destination after the reception is completed.
