Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a facsimile transmission method in which when a document is reduced and transmitted, vertical and
The transmission time is reduced by converting the horizontal direction by 90 degrees.

FIG. 1 is an electrical circuit diagram of a main part for explaining an embodiment of the present invention, that is, an electrical circuit diagram of a transmitting side of a facsimile machine. 4 is a data encoding device, 5 is a modulation/demodulation device, and 6 is an image converting device added.
is a line control device that, as is well known, sets a document on the document table of a facsimile machine, scans the document with a scanner, reduces the read image optically or electrically, and transmits it. , in conventional devices that are not equipped with an image conversion device, the reduced or enlarged image is transmitted as is.
When a size original is reduced to B5 size and sent, the transmitted reduced image is as shown by the solid line in Figure 2b, and
The received recording image is shown by the solid line in Figure 2c, but as is clear from Figure 2c, the B4 size area occupies the transmission length of the B5 size, which was reduced in Figure 2b. As a result, a margin A is created on the recording paper, resulting in a disadvantage of wasting transmission time.

The present invention was made to solve the above-mentioned drawbacks of the prior art.As mentioned above, an image conversion device is provided next to the reduction device, and the vertical and horizontal directions of the reduced image are converted by 90 degrees. This is intended to shorten transmission time.

FIG. 3 is a diagram for explaining the operating principle of the present invention, in which a is a document, b is a reduced image, c is a transmitted image,
d indicates a recorded image, but as shown in the figure, when a B4 size original is reduced to B5 size and sent, the vertical and horizontal directions of the reduced image (see Figure 3b) are converted by 90 degrees,
If this is used as a transmission image (see FIG. 3c), there is no waste in transmission time, and the transmission time can be shortened. Although the case where a B4 size original is reduced to B5 size and transmitted is described above, the present invention is not limited to the above embodiment, and the same applies to the case where an A size original is transmitted. Generally speaking, BN size manuscripts are printed in B (N+
It is suitable for application to 1) or when transmitting an AN size original after reducing it to A(N+1).

FIG. 4 is a diagram showing an example of a detailed electric circuit of the third part of the image conversion device shown in FIG. In addition, the vertical and horizontal directions of the image information input signal are converted by 90 degrees in the image information memory 12 under the control of the row counter 10 and the column counter 11, and then sent out as the image information output signal.

As is clear from the above description, according to the present invention, when a facsimile device sends a reduced image, the vertical and horizontal directions of the read image are converted by 90 degrees before being sent, thereby eliminating the blank space on the recording paper. , it is possible to eliminate wasted transmission time and shorten the transmission time.

That is, when the image information is reduced, the transmission length can be shortened accordingly, the transmission time can be shortened, and the image information can be efficiently sent to the other party.

Claims (1)

[Claims] 1 In a facsimile transmission method that reads a document, reduces the read image, converts the reduced image, and sends the converted image, when converting the image, the BN size document information is sent to B(N+1).
The original information of the AN size or AN size is reduced to the A(N+1) size, and the reduced original information is converted to 90 degrees vertically and horizontally using an image conversion means, and the original before and after conversion is converted. A facsimile transmission method characterized by transmitting by shortening the transmission length after conversion without changing the width.
