Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine capable of two-sided communication.

[0002]

2. Description of the Related Art A conventional facsimile machine reads, encodes and transmits one side (front side) of document information at the time of transmission,
Further, at the time of reception, the received information was recorded on one side (front side).

However, in ITU-T in February 2000,
The protocol for double-sided communication has been decided, and it is expected that facsimile machines equipped with the same function will spread in the future in addition to resource saving.

[0004]

[Problems to be Solved by the Invention] However, ITU
In the two-sided communication determined at -T, the transmitted information is reproduced at the receiver by the same information, and only a part of the information is output at the receiving side.

Here, no particular consideration has been given to the method of recording the output of a plurality of copies of the received information. For example, even when the output of a large number of copies is selected, single-sided printing is performed and all the data are output on the recording paper. There was a drawback that it could not be used effectively.

[0006]

According to the first aspect of the present invention,
In a facsimile device capable of facsimile communication of double-sided information, a receiver notifies a transmitter of the presence / absence of a double-sided reception function, a means from the transmitter specifies double-sided communication to the receiver,
It has become possible to have a means for outputting a plurality of received information and a means for registering an output method when outputting a plurality of copies.

According to the second aspect of the present invention, in the first aspect of the present invention, when a plurality of copies are selected, it is possible to output a plurality of copies based on the surface information designated during communication.

According to the third aspect of the present invention, in the first aspect of the present invention, when the plural copies output is selected, all the received information can be recorded on both sides.

According to the fourth aspect of the present invention, in the first aspect of the present invention, when a plurality of copies are selected, the first copy is output based on the surface information specified during communication, and the second copy is output. After that, it became possible to record all received information on both sides. As a result, in a facsimile apparatus capable of receiving both sides / recording both sides, when a plurality of copies are selected, the number of output sheets increases, so that it is possible to output a plurality of copies according to the user's preference and to effectively use the recording paper. It has become possible and easy for users to use.
