Abstract

PURPOSE: To recognize a transmitter at the receiver side by adding the optional header information at the transmitter side. CONSTITUTION: The transmitted images are read by a scanner unit 1-1 and stored in a RAM 1-3. Then the information on the necessity for addition of the header information and the header information itself are sent to a CPU 1-2 from a panel unit 1-6 by the key input operations of an operator. The read images are sent to an image processing unit 1-5, and the character and image headers are added to the images as the information on the transmitter side so that these headers are not overlapping the CIL of the terminal of the opposite party side. These images and information are stored again in the RAM 1-3. Then the images stored in the RAM 1-3 are transmitted via a CCU unit 1-7.

2. Description of the Related Art Conventionally, in a G4 facsimile machine,
In order to indicate from where the received image is transmitted, the receiving side has added header information called a call identification line (hereinafter referred to as CIL).

FIG. 2 is an explanatory diagram showing the flow of image data when a header is not added on the transmitting side in a conventional G4 facsimile apparatus.

First, the image 2-1 is the scanner unit 1
The image read from -1 is shown, and even in the image 2-2 to be actually transmitted, the image is transmitted without adding characters or images as information on the transmitting side (name of the recipient, etc.). Then, an image 2-3 shows an image when the received image is actually output, and header information created from the procedure signal on the receiving side is added.

FIG. 3 is an explanatory diagram showing the flow of image data in the conventional G4 facsimile apparatus when header information is internally added to the beginning of a transmission image on the transmitting side and the image is transmitted.

First, the image 3-1 is the scanner unit 1
-1 shows an image read from -1, and image 3-2 is
It shows a state in which characters and images are added to the image as information on the sending side (name of sender, etc.), and this image is actually sent. Then, an image 3-3 shows an image when the received image is actually output. As illustrated, in the G4 facsimile, since the CIL is added to the received image, the header added on the transmitting side is overwritten.

[0007]

However, the above C
Since the IL has the content that uniformly shows the terminal information of the transmission source, there is a drawback in that it is not possible to identify the sender of the image. Further, even when the header is added on the transmitting side, it is overwritten by the CIL on the receiving side, so that it does not appear in the received image and the same problem occurs.

[0008] Therefore, an object of the present invention is to provide a facsimile apparatus which allows a receiving side to recognize who sent information on the transmitting side.
