DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Field of Industrial Application) The present invention relates to a facsimile device connected to an integrated digital service network (hereinafter referred to as 15DN).

(Prior Art) In general, facsimile machines connected to public telephone lines or DDX lines are designed to perform either voice communication or image communication, or to perform both of them alternately.

This is because each of the above lines basically has a bandwidth for one channel of information, so in order to avoid the deterioration of information and the reduction in transmission speed that would be caused by transmitting audio information and image information simultaneously using this narrow bandwidth. These are the measures to be taken.

On the other hand, today, with the practical use of I5DN, unique communication services are being established for facsimile machines connected to it.

For example, services with different characteristics such as tsDNl, telephone, telex, and facsimile equipment have multiple IW information channels to handle the equipment in an integrated manner.
By using the two vacant information channels, it has become possible to simultaneously transmit voice VI information and image information.

As a concrete example, in this type of conventional facsimile machine,
During image communication using the G4 facsimile procedure on the first information channel, there is an incoming telephone call on the second information channel, and if this is an incoming voice call, the state shifts to simultaneous image and voice communication and the operation is 1! can continue.

However, under such conditions, if the incoming telephone call to the second information channel is a non-voice incoming call, that is, an incoming call for image communication using the G3 facsimile procedure, the state cannot shift to simultaneous communication between images, and the The patient had no choice but to undergo treatment as a medium or amputation.

The reason for this is that in the first place, few conventional facsimile machines of this type have a control unit for G3 facsimile communication, and even if they do have a Possible reasons include the fact that the G3 printer section and printer section are in use and cannot be operated redundantly for G3 door-to-door communication.

For the same reason, when a telephone call is made on the second information channel during a G4 facsimile 311 transmission on the first information channel, if this is a g re-call, the state can shift to simultaneous image and voice communication, but the G3 When a call is made for facsimile communication, it has no choice but to be treated as busy or disconnected.

(Problems to be Solved by the Invention) As described above, in the conventional facsimile apparatus described above, when voice communication occurs on the second information channel during G4 facsimile communication on the first information channel, the image
This can be handled by transitioning to the simultaneous voice communication state, but under the same conditions, non-voice communication, i.e. G3, can be transferred to the second information channel.
When facsimile communication is required, the G3 facsimile communication cannot be processed at the same time as the G4 facsimile communication, resulting in a problem that truly efficient operation cannot be achieved.

The present invention has been made in view of the above circumstances, and even if G3 facsimile communication occurs on the second information channel during G4 facsimile communication on the first information channel, this is processed simultaneously with the G4 facsimile communication. The purpose of the present invention is to provide a facsimile machine that enables more efficient operation.
