Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of an electronic file device having an image transmitting / receiving function according to the present invention.

The resolution of the electronic filing apparatus according to this embodiment is 400 dpi, and one scanning line is divided into two to transmit and receive. The electronic file device 1 is
Public telephone line 2 via the facsimile communication control device 10
0, and the electronic file device 51 is connected to the public telephone line 20 via the facsimile communication control device 70. Image input devices 2, 52 for inputting image information to the electronic file devices 1 and 51, respectively.
Image output devices 4 and 54 for outputting image information, and display devices 6 and 56 for displaying image information and operation information are connected.

The electronic file devices 1 and 51 are interfaces 3 and 53 for connecting to the image input devices 2 and 52, interfaces 5 and 55 for connecting to the image output devices 4 and 54, and the facsimile communication control device 1.
Interfaces 11 and 71 for connecting to 0 and 70
Is equipped with.

The electronic filing devices 1 and 51 are respectively provided with image processing processors 9 and 79, which are particularly relevant to the present invention. Then, the image processor functionally divides one image into two images by dividing the image data on one scanning line into the image data on two scanning lines, and this dividing means. Transmitting means for sequentially transmitting the image data on the scanning lines divided by, receiving means for sequentially receiving the image data on the scanning lines transmitted by the transmitting means, and 1 for receiving the image data on the two scanning lines.
And a combining unit that combines the two images divided by the dividing unit into one image by combining the image data on the scanning line of the book. Therefore, the image processing processor on the image transmitting side operates the dividing means and the transmitting means, and the image processing processor on the image receiving side operates the receiving means and the synthesizing means. These dividing means, transmitting means, receiving means, and synthesizing means are actually executed by the image processor based on a program stored in a ROM (not shown) in the electronic file device.

Reference numerals 30 and 31 are public telephone lines 2.
It is an external facsimile machine connected to 0.

Next, the operation will be described with reference to the flow chart of FIG. Hereinafter, the electronic file device 1 will be described as a transmitting side, and the electronic file device 51 will be described as a receiving side.

In general, the user divides an image, transmits it,
Processing such as reception and combination is executed in an interactive manner while referring to instructions displayed on the display device 6.

After the image file to be transmitted designated by the user is searched (step S1) and the image is displayed on the display device 6 (step S2), the image transmission is instructed (step S3).

Then, in response to this instruction, the image processor 9 divides the image data on one scanning line of the designated image into the image data on two scanning lines to divide one image into two images. Yes (step S4). This image segmentation is more apparent with reference to FIG. 1 to send
In one image 101, X indicates the main scanning direction and Y indicates the sub scanning direction. And the image 101 shows a plurality of Xs.
Image data on scanning lines in each direction, and each scanning line includes a plurality of pixel data. The dividing means divides each scanning line into two at the center, thereby converting the image 101 into the image 10
2 and the image 103. The transmitting means sequentially transmits the two images 102 and 103 obtained as a result of the division by the dividing means, and sequentially transmits the image data on the scanning lines forming them, thereby transmitting them to the facsimile communication control apparatus 10 through the interface 11 ( Step S5).

The facsimile communication control device 10 first receives the image 102 through the interface 11 and stores it in the data storage unit, and then receives the image 103 and stores it in the data storage unit (step S6). Thereafter, the facsimile communication control device 10 reads the image 102 from the data storage unit, transmits the image 102 to the facsimile communication control 70 through the public telephone line 20 (step S7), and then the image 10
3 is read from the data storage unit and transmitted to the facsimile communication control 70 through the public telephone line 20 (step S
8).

When the facsimile communication control device 70 receives the images 102 and 103 via the public telephone line 20, they are stored in the data storage section (step S1).
0, S11). After that, when a predetermined command is received from the electronic file device 51, the facsimile communication control device 70
Sequentially displays the images 102 and 103 stored in the data storage unit,
It is transmitted to the electronic file device 51 (step S12).

The electronic file device 51 sequentially receives the image data on each scanning line constituting each of the images 102 and 103 from the facsimile communication control device 70 through the interface 71.
103 is received. Then, the combining means receives the received 2
By receiving the image data on each scanning line of one image 102, 103 and combining the image data on two scanning lines with the image data on one scanning line, two divided images 102, 103 are obtained. Is combined into one image 101 (step S13).

The electronic file device 51 displays the image 101 which is the result of this combination on the display device 56 (step S1).
4) Further, predetermined internal processing such as image registration is performed (step S15).

Therefore, even if the number of pixels per scanning line forming the image data exceeds the number of pixels per scanning line defined in the facsimile communication, the image data can be transmitted by the facsimile communication. Can be sent and received.

In the present embodiment, the image 101 is divided into two images 102 and 103, the image data on the scanning line forming the image 102 is transmitted, and then the image data on the scanning line forming the image 103 is transmitted. I sent it, but image 101
Each scanning line of 2 is divided into two and two scanning lines are paired, and after transmitting one of them, the other is continuously transmitted, so that the image data on the scanning line is transmitted. Good.

Further, in the present embodiment, the scanning line is divided into two, but the number of divisions can be three or more, and in that case, a higher resolution image can be transmitted and received.

Although only the case where an image is transmitted from one electronic file device 1 to the other electronic file device 51 has been described here, the electronic file 51 may be the transmitting side.

[0026]

As described above, the electronic file device having the image transmitting / receiving function according to the present invention divides image data into image data of a plurality of areas, and a plurality of areas obtained by the dividing means. Transmitting means for sequentially transmitting the image data to the public telephone line via the facsimile communication control device; receiving means for receiving the image data of a plurality of areas transmitted by the transmitting means via the facsimile communication control device; Since the image forming apparatus is provided with a synthesizing unit that synthesizes image data of a plurality of areas received by the receiving unit and reconstructs an image, the number of pixels per scanning line that constitutes the image data is defined in facsimile communication. Even when the number of pixels per scanning line is exceeded, image data can be transmitted and received by facsimile communication.
