Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having an automatic document feeder, and more particularly to a facsimile machine improved so that both sides of a double-sided printed original can be transmitted by one line connection.

[0002]

2. Description of the Related Art Conventionally, a facsimile machine having an automatic document feeder has been constructed as shown in FIG. That is, a document is set on the document supply tray 13, and the document set on the document supply tray 13 is set on the document supply tray 13.
Are separated from each other by the difference in friction coefficient between the driving roller 14 and the rubber tongue 18 and are taken out one by one, and the image of the original is read by an original reading unit (not shown).
It was configured to drain via 17.

Here, when the document is emptied in the document supply tray 13, that is, the next document is not detected by the document detection sensor 15 within a certain time after the last document is conveyed from the document supply tray 13. When there are no more originals to be transmitted, the procedure end signal EOP is sent to the destination facsimile machine, that is, the receiving side facsimile machine to disconnect the line to the destination facsimile machine.

FIG. 6 is a sequence diagram showing the transmission / reception of signals to / from the receiving side facsimile apparatus. In response to a call from the transmitting side facsimile apparatus, the receiving side facsimile apparatus sends a digital identification signal DIS. Is returned, the sending facsimile machine sends a digital command signal DCS to the receiving facsimile machine, and then sends a training check signal TCF. Here, a reception preparation confirmation signal CF is received from the reception side facsimile device.
When R is returned, the transmission side facsimile device transmits the image information PIX read from the document taken out from the document supply tray 13 to the reception side facsimile device, and the document detection sensor 15 causes the document in the document supply tray 13 to be empty. When it is detected, the transmitting side facsimile device sends a procedure end signal EOP to the receiving side facsimile device, receives the message confirmation signal MCF from the receiving side facsimile device, and then transmits to the receiving side facsimile device. The disconnection command signal DCN is transmitted to disconnect the line to the receiving facsimile machine.

Now, in the case of transmitting a so-called double-sided original in which images are formed on both front and back sides in the conventional facsimile apparatus having such a structure, first, the double-sided original is fed with its front surface as a reading surface. Tray 1
3, the front side image is read by reading the front side image, and then the double sided document discharged from the facsimile apparatus for which the front side image has been read is turned over again and again fed to the document feeding tray. By setting it to 13 and reading the image on the back side, the operation for transmitting the image on the back side is performed. However, in this case, in the conventional facsimile apparatus, when the original detection sensor 15 detects that the original set on the original supply tray 13 has become empty, the transmitting-side facsimile apparatus performs a procedure for the receiving-side facsimile apparatus. End signal EO
Since it is configured to send P to disconnect the line to the receiving side facsimile apparatus, when the front side original set on the original supply tray 13 with the front side as the reading surface is no longer present on the original supply tray 13, The line with the receiving facsimile machine will be disconnected.

Therefore, in the conventional facsimile apparatus, after the transmission of the image on the front side is completed, the facsimile number of the other party is input again and the line with the receiving side facsimile apparatus is established by the procedure shown in FIG. I had to connect and send the back image.

[0007]

As described above, in the conventional facsimile apparatus, when transmitting a two-sided printing original, the operator does not perform the operation of inputting the facsimile number of the other party and connecting the line twice. Not only that, it has to repeat a troublesome operation, and it has been an obstacle to prompt facsimile transmission.

Therefore, according to the present invention, in order to reduce the burden on the operator and increase the transmission processing speed, one-sided printing originals are printed.
It is an object of the present invention to provide a facsimile device that can be transmitted with one line connection.

[0009]
