BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, for example.

[0002]

2. Description of the Related Art Generally, a facsimile machine transmits image information of a document as a communication text to a physically distant place. This facsimile machine is used for various purposes. For example, sending of materials and notice of meetings.

Incidentally, the called party, which has received the communication message transmitted from the calling side, sometimes adds characters etc. to the communication statement and transmits the message to the calling side. Such a communication message is often transmitted from the calling side on the assumption that it will be returned. For example, there is a case where the calling side operator wants an answer of attendance in response to the conference notification.

However, it is difficult for the facsimile device to maintain the image information of the transmitted communication text at the image quality level equivalent to that of the original document, and if the transmitted communication text is retransmitted, the image quality of the communication text is not deteriorated. Very big.

Therefore, it may be difficult for the calling side operator to read the content of the communication message retransmitted (replied) from the called side. In addition, the called party that sends back the message sends a reply with the same amount of time as the time required to send the original document in order to add a few characters to the message and send it to the calling party. There has been a problem that the use efficiency of the limited communication line is lowered because it has to be spent.

[0006]

As described above, when the called party adds characters or the like to the communication text transmitted from the calling side and returns the communication text, the communication text causes deterioration in image quality due to transmission between facsimile machines. Since it is strongly affected, there is a problem that the calling side operator may have difficulty in reading the contents of the communication message returned from the called side.

Therefore, according to the present invention, since this problem is eliminated and the returned communication message is less likely to be affected by the image quality deterioration due to the transmission between the facsimile devices, the operator on the calling side can confirm the content of the communication message. The present invention provides a facsimile device that can be easily read.

[0008]

In order to achieve the above object, according to the present invention, first image information transmitted and received in primary transmission and primary reception, and arbitrary image information in the first image information. Second image information added with, third image information transmitted and received by secondary transmission and secondary reception, and first selecting means for selectively selecting the primary transmission and the secondary transmission.

Next, FIG. 11 is a flow chart showing the transmitting operation by the main controller 1 of the facsimile apparatus according to the present invention. First, the main control unit 1 operates the document placement detector 14
It is determined whether or not the document is detected by the presence or absence of the document detection signal (S201). When the document is detected, the main control unit 1 determines whether or not a reply-compatible transmission instruction (original transmission, reply) is input from the operation panel 4 (S202). If there is no reply response transmission instruction, the main control unit 1 makes a dial call as normal transmission (S203), converts the document into image information by the reading unit 16 and transmits it (S204, S205, S206, S).
207).

On the other hand, the main control unit 1, which has determined in step 202 that the reply correspondence transmission instruction has been input, determines whether or not the system serial number has been input (S208). If the system serial number is not input, the main control unit 1 determines the storage address for original transmission (S209), and based on this address, the image information read from the document by the reading unit 16 is stored in the image memory. The data are sequentially stored in 12 (S210). At this time, the main control unit 1 sets a new system serial number and a step 209.
The storage address determined in step 3 is stored in the RAM 3, and the transmission source flag is set to 1 (S211). Then, a dial call is made (S212), and the main control unit 1 follows the tonal procedure to send a TSI (my dial information) signal and an AAA (R) signal.
Send out the system serial number stored in AM3 (S
213). After that, the main control unit 1 reads out the image information a from the image memory 12 according to the address stored in the RAM 3 and transmits it (S214, S215, S216).

On the other hand, the main control section 1 which has judged in step 208 that the system serial number has been input, temporarily determines the storage address for reply (S217) and reads the reading section 1 from the reply document.
The image information b read in 6 is sequentially stored in the image memory 12 (S218). Then, the main control unit 1 retrieves the storage address from the RAM 3 based on the input system serial number (S219). From the image memory 12, the main control unit 1
The image information a and the image information b are read out according to the storage address for reply and the storage address based on the system serial number (S
220, S221). The main control unit 1 compares the image information a and the image information b in the image comparison unit 19 (S222), and the matched image information of the image information b is changed from the valid recording signal (1) to the invalid recording signal (0). (S223, S224).
Then, the main control unit 1 retrieves the transmission source dial information and the transmission source system serial number from the RAM 3, makes a dial call (S225), and follows the AA according to the tonal procedure.
An A (source system serial number) signal is transmitted (S22).
6). Finally, the main control unit 1 executes steps 223 and 22.
The image information c converted from the image information b in 4 is stored in the image memory 12
Read from and transmit (S227, S228, S22
9).

Next, FIG. 10 is a flow chart showing the receiving operation by the main controller 1 of the facsimile apparatus according to the present invention. First, after receiving the ringing signal, the main control unit 1 determines whether the AAA signal is received in a predetermined tonal procedure.
Judges (S100), and if the AAA signal is not received, the image information received thereafter is sequentially printed by the recording unit 13 to the end (S102, S103, S104).

On the other hand, in step 100, the main controller 1, which has determined that the AAA signal has been received, determines the storage address for reception (S101) and stores the received image information in the image memory 12 based on the address (S101). S105). Then, the main control unit 1 compares whether the transmission source system serial number obtained from the received AAA signal matches the main system serial number stored in the RAM 3 (S106), and the transmission source flag of the main system serial number is 1 It is determined (S1
19).

If the transmission source flag is 1, and this system serial number does not match the received transmission source system serial number, this system serial number newly issued by the receiving operation and the received transmission source dial information and The transmission source system serial number and the image information storage address are stored in the RAM 3 (S1).
07). Next, the main control unit 1 creates an additional image d based on the system serial number in the image creating unit 17 (S108),
The recording unit 13 prints the additional image d. After that, the main control unit 1 reads out the image information from the image memory 12 according to the address stored in the RAM 3 and prints it on the recording unit 13 (S110, 111, 112).

In step 119, the transmission source flag is set to 1
The main control unit 1 which has determined that the storage address is retrieved from the RAM 3 based on the coincident system serial number (S1).
13). Then, the main control unit 1 reads out the image information a from the image memory 12 according to this storage address (S114), and also reads out the image information c from the image memory 12 according to the receiving storage address (S115), and the image information a.
And the image information c are combined by the image creating unit 17 (S11).
6). The combined image information is stored in the storage address for reception of the image memory 12 (S117), and the main control unit 1 repeats the combination until all the image information is combined (S11).
8). The printing of the combined image information is performed in step 110.
To 112.

As described above, according to the present invention, when the called side adds a character or the like to the communication text transmitted from the calling side and returns the communication text, the image information transmitted between the facsimile devices is the added writing information. Since it is only image information such as written characters, it is less susceptible to image quality deterioration due to the performance of the facsimile apparatus and the quality of the communication line, and therefore the calling side operator can easily read the contents of the communication text.

Further, according to the present invention, the image information to be returned is the image information in units of one page, but in the image information other than a small portion of the effective recording signal (1) such as added characters. Is an invalid recording signal (0), and the invalid recording signal (0) can be efficiently encoded by the encoding / decoding unit 18. Therefore, the image information significantly shortened by the encoding has a transmission time It is short and contributes to the improvement of communication efficiency.

By the way, in the above description, the image information to be returned is the image information for each page, but the facsimile device manages the composite position information of the image information so that the image information to be returned is the added characters. If only the image information area is used, the communication efficiency can be further improved.

[0031]

According to the present invention, when the called party adds characters or the like to the communication text transmitted from the calling party and returns it,
Since the image information transmitted between the facsimile devices is only the image information such as the added characters, it is less susceptible to image quality deterioration due to the performance of the facsimile device and the quality of the communication line. The contents of the message can be easily read.
