Abstract

PURPOSE:To eliminate a blank part in recording paper and to shorten a transmission time, by transmitting a read picture while changing its vertical and horizontal directions by 90 deg. in contraction or enlargement transmission mode. CONSTITUTION:In a figure, 10 is a row counter, 11 is a column counter, and 12 is a picture information memory; and the vertical and horizontal directions of a picture information input signal are changed by 90 deg. in the picture memory 12 under the control of the row counter 10 and column counter 11 to transmit the resulting picture information output signal. In general, when an original of BN or AN size is transmitted while contracting to B(N+1) or A(N+1) size, or when an original of the BN or AN size is transmitted while enlarging to the B(N-1) or A(N-1) size, said signal is used suitably.

Description

DETAILED DESCRIPTION OF THE INVENTION In a facsimile machine, when a document is reduced or enlarged and transmitted, the vertical and horizontal directions of the read image are converted by 90 degrees before transmission. This eliminates the blank space and eliminates the whitening of the transmission time.

FIG. 1 is a main electrical circuit diagram for explaining one embodiment of the present invention, that is, transmission 6. of a facsimile machine. j+ City, air mass schematic diagram (in the figure, 1 is a scanner, 2 is a reduction/enlargement device, 3 is an image conversion device added according to the present invention, 4 is a data input device, 5 is a modem device, and 6 is a line control device. As is well known, a facsimile machine places a document on the document table of a facsimile machine, scans the document with a scanner, and optically or electrically reduces or enlarges the read image before transmitting it. In conventional devices that are not equipped with an image conversion device, the reduced or enlarged image is sent as is. When transmitting after reducing the image to However, as is clear from FIG. 2(c), there is a drawback that a white area A is formed on the recording paper, resulting in wasted transmission time.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art.As mentioned above, an image conversion device is provided next to the reduction/enlargement device, and a half-width Convert the horizontal direction by 90 and record as described above 1111
The blank space in the image has been removed.

FIG. 3 is a diagram for explaining the operating principle of the present invention.
a) is the original, (b) is the reduced image, (C) is the transmitted image, (
d) shows a recorded image, but as shown in the figure, when an 84-size original is reduced to 85-size and sent, the reduced image (Figure 3 (
b) If the vertical and horizontal directions of
(see Figure (d)), there is no blank space, so there is no waste in transmission time, and the transmission time can be shortened. Although the case where an 84-size original is reduced to 85-size and transmitted has been described above, the present invention is not limited to the above embodiment, and an A-size original can also be enlarged and transmitted. The same thing applies when transmitting a B or N size original to B(N+1) or an AN size original to A(N+1), or when transmitting an 8M original.
Transfer a size original to B(N-1) or an AN size document to A(N-1)
It is suitable for application to cases such as when enlarging and transmitting 1).

FIG. 4 shows details of the three parts of the image conversion device shown in FIG.
'%, This is a diagram showing an example of an air mass path. In the diagram, 10 is a row counter, 11 is a column counter, and 12 is an image information memory. As shown in the figure, the vertical and horizontal directions of the image information input signal are stored in the image information memory. At step 12, the signal is subjected to 90 conversion under the control of row counter 1() and column counter 11, and is sent out as an image information output signal.

More than 65? As is clear, according to the present invention,
When sending a reduced or enlarged facsimile, the vertical and horizontal directions of the illumination image are converted by 90° before the next step is sent, and the margins on the recording paper are eliminated, reducing wasted transmission time. , the transmission time can be shortened.
