Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an image communication apparatus such as a facsimile apparatus and, more particularly, to an image communication apparatus capable of communicating a subaddress signal.

[0002]

2. Description of the Related Art A conventional facsimile apparatus capable of communicating a sub-address signal is defined by an ITU-T recommendation, and a transmitter prepares for a specific memory box or a specific destination on the receiver side in preparation for the transmitter side to specify. Transmit the sub-address signal to the receiver.

[0003]

By doing so, when the facsimile machine on the receiver side is connected to the LAN and accommodates a plurality of personal computers, the operator of the transmitter can receive the data as a receiving party. PC can be designated by a sub-address signal. In addition, the conventional ITU-T Recommendation T. According to 33, a plurality of extension numbers can be designated from the transmitter, and a plurality of personal computers accommodated in the receiver can be transmitted as destinations.

However, when the message is transmitted to a plurality of personal computers on the basis of the extension number, the user who has received the transmission information transmits the message to a destination to which the information was transmitted or a destination to which the same information as the information was received. There is a problem that even if an attempt is made to transmit, it cannot be transmitted.

One of the reasons is that the individual information on the transmitter side is not known, and another is the definition of the FIF of the sub-address signal.

[0006] The above problem is a problem that also occurs in an image communication apparatus other than the facsimile apparatus.

According to the present invention, when data is transmitted from a personal computer PC1 connected to an image communication apparatus A to personal computers PC2 and PC4 connected to an image communication apparatus B, the PC2 of the image communication apparatus B is used. It is an object of the present invention to provide an image communication apparatus capable of reliably transmitting facsimile information to a personal computer PC4 on its own network and a personal computer PC1 connected to the image communication apparatus A. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a facsimile apparatus FS1 according to one embodiment of the present invention.

An NCU (network control unit) 2 connects to a terminal of the line to use the telephone network for data communication and the like.
It controls connection of the telephone exchange network, switches to a data communication path, and holds a loop. The NCU 2 connects the telephone line 2a to the telephone when the signal level (signal line 20a) from the control circuit 20 is "0", and connects the telephone line 2a when the signal level is "1".
Is connected to the facsimile machine side. In a normal state, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, sends the transmission signal from the addition circuit 12 to the telephone line 2a via the NCU 2, and transmits the signal from the other party via the NCU 2 And sends it to the modem 8 via the signal line 6a.

The modem 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27ter, V.I. 29, V.I. 17, V.I.
