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 transmitting a subaddress signal.

[0002]

2. Description of the Related Art A conventional facsimile apparatus capable of communicating a subaddress signal can request a relay broadcast by transmitting a subaddress signal.

[0003] Specifically, a facsimile apparatus of a receiver which transmits, for example, "1234" as a sub-address signal from a transmitter to a receiver and receives the sub-address signal "1234", for example, has destinations A, B, C , D, E, F
And broadcast to.

[0004]

However, in the above conventional example, the destination receiving the subaddress signal "1234" transmits to all of the destinations A, B, C, D, E, and F. There is a disadvantage that there is news. That is, there is a disadvantage that only the destination receiving the sub-address signal “1234” bears the communication cost.

[0005] In order to solve this drawback, at the time of the first transmission, information of destinations A, B, C, D, E, and F is transmitted together with the image signal. , Transmitting information of destinations B, C, D, E, and F together with the image signal, destination A making a call to destination B, and transmitting information of destinations C, D, E, and F together with the image signal. Can be considered.

However, in the above-mentioned method, since the destination is directly specified, there is a problem that the pre-procedure required for the destination specification becomes long and complicated.

[0007] This problem also occurs in other image communication devices in the same manner as described above.

The present invention provides an image communication apparatus that enables relay broadcast transmission while sharing the communication cost for each destination only by adding a minor change to the protocol currently recommended by ITU-T. The purpose is to provide.

[0009]

SUMMARY OF THE INVENTION According to the present invention, there is provided an image communication apparatus capable of transmitting a sub-address signal. This is an image communication apparatus having a designation unit for designating a relay broadcast to be delivered to each destination from a transmitter to a receiver, and a registration unit corresponding to a memory box and registering a sub-address signal and a communication specification.

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 in order 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 (CML off) or connects the telephone line 2a to the facsimile apparatus (CML on) under the control of the bus 36. 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. The signal is received and sent to the modem 8 via the signal line 6a.

The modulator / demodulator 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27ter, V.I. 29, V.I. 17, V.I.
This is a modulator / demodulator that performs modulation and demodulation based on the signal 34, and each transmission mode is designated by the control of the bus 36. The modulator / demodulator 8 receives a transmission signal from the bus 36, outputs modulated data to the signal line 8a, receives a received signal output to the signal line 6a, and outputs demodulated data to the bus 36.

The circuit 10 for transmitting the ANSam signal determines whether or not to transmit the ANSam signal based on the signal from the bus 36.

The addition circuit 12 receives the information of the signal line 8a, the information of the signal line 10a, and the information of the signal line 22a, and outputs a result of the addition to the signal line 12a.

The read circuit 14 transmits read data to the bus 3
6 is output.

The recording circuit 16 sequentially records the information output to the bus 36 line by line.

The memory circuit 18 is used to store raw information of read data or encoded information, and also stores received information or decoded information, etc. .

The CPU (central processing unit) 20 is for executing the overall control processing of the facsimile apparatus FS1 and the facsimile transmission control, and its control program is stored in a ROM (read only memory) 34. I have.

The calling circuit 22 inputs a telephone number via the bus 36 and sends out a DTMF selection signal to the signal line 22a.

The operation unit 24 includes a one-touch dial, a speed dial, a numeric keypad, a * / # key, a start key, a set key, a stop key, a registration key for the circuit 32, and other function keys. Output to the bus 36.

Relay broadcast selection button 2 for distribution to each destination
6, when the relay broadcast selection button 26 is pressed, a pressing pulse is generated on the signal line 26a.

Relay broadcast display circuit 28 for distributing one destination at a time
When a clear pulse is generated on the bus 36, no display is performed, and every time a depressed pulse is generated on the signal line 26a,
“Display” → “not display” → “display” is repeated, and information indicating whether or not “display” is output via the signal line 26a.

When the sub-address signal input button 30 is pressed, the bus 36
Generates a pressing pulse.

Corresponding to the memory box,
The circuit 32 for registering the communication specification, for example, sends the message via the bus 36 to the memory box 01, indicating that “the subaddress signal is 1234, the transfer destination is the destination C, and a communication error occurs when a communication error occurs during the transfer. Is the destination A ".

The ROM 34 is a memory for storing a control program. The control program includes a notifying means for notifying the transmitter of the presence or absence of a relay broadcast function for distributing one destination at a receiver, and a relay for distributing each destination. Broadcast transmission
This is a control program that implements a designation unit that designates a receiver from a transmitter, and a registration unit that registers a sub-address signal and communication specifications corresponding to a memory box.

[0027] The control program is a control program in which the receiver changes a protocol in a next transmission operation depending on whether or not the relay broadcast for distributing the addresses one by one is designated. If the receiver does not specify the relay broadcast for delivering the destination one by one, the receiver performs the next transmission operation without transmitting the sub-address signal based on the next received sub-address signal,
On the other hand, when the relay broadcast for delivering one destination at a time is designated, a control program for transmitting the same sub-address signal as the received sub-address signal based on the next received sub-address signal and executing the next transmission operation It is.
