Abstract

PURPOSE:To reduce the transmission time to the utmost and to decreases remarkably the communication cost of a facsimile equipment by describing a mark to the peripheral of transmission paper in parallel with the main and sub scanning directions respectively, using a microprocessor built in the facsimile transmission side device so as to detect electrically the said mark and setting a space signal processing area to the transmission paper according to the described position of the said mark. CONSTITUTION:When a bar code A at the left of the upper side is scanned (arrow j) and a picture signal is fed to a control section 9, a microprocessor 28 reads this signal and generates two kinds of commands and the information of one side described on the left side paper face from a vertical line (e) passing through the code A is skipped. Then a bar code B at the right of the upper side is scanned, a piece of information described to the right side of a vertical line (f) passing through the bar code B is processed as a space signal. Thus, all information included at the upper part of a horizontal line (g), the lower part of the (h), the left of the vertical line (e) and the right part of the (f) is processed as a space signal, and the information in a section 26 trimmed by hatching finally, that is, only a graph 20 is transmitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an economical facsimile transmission method in which a portion of a transmission sheet can be freely selected and transmitted.

[Conventional technology]

An effective way to save facsimile communication costs is to shorten transmission time.While manufacturers strive to increase the speed of their devices, users also remove unnecessary figures, characters, etc. from the sending paper before transmission. In this case, various methods were used, such as cutting out the necessary parts of the paper, or making copies of only the parts that were to be transmitted, and then transmitting them.

[Problem that the invention seeks to solve]

However, with the above method, there is a problem in that the time and material loss required for preparing the transmission paper is large, and the cost saving effect cannot be sufficiently achieved.

[Means for Solving Problems 7] The present invention was made to solve the above-mentioned problems, and marks are written on the periphery of the sending paper parallel to the main and sub-scanning directions. electrically detecting the mark using a microprocessor built into the transmitting side;
A margin signal processing area is set on the transmission paper according to the position of the mark.

[For production]

Since all but the necessary portion of the paper containing the information to be transmitted is subjected to margin signal processing, the amount of transmitted signals is minimized, and as a result, the transmission time is shortened to the maximum. Further, since it is only necessary to mark the transmission paper, preparation for transmission is simple, and communication costs can be substantially reduced.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. The transmission method and facsimile operation according to the first embodiment of the present invention will be explained with reference to FIGS. 4 is a roller that feeds the transmission paper 3 in the direction of arrow a to scan the plane, 5 is a motor for driving the roller, 6 is a fluorescent lamp, 7 is a lens, and 8 is a solid-state imaging type ( CCD) LSIS tie sensor; 9 is a control section consisting of a pulse generation circuit and a signal processing circuit; 1o is a modulator that modulates the signal sent from the control section 9 and outputs it to the transmission line 12; 13 is a demodulator; 14 is a 15 is a thermal head, 15 is a roller, 16 is a receiving paper, p is a main scanning direction, and q is a sub-scanning direction.

There is no need to describe the principles of imaging and signal processing that are already known, but to outline the operation of the circuit related to the present invention, light reflected from the figures, characters, and blank spaces on the transmission paper is The pulse train passes through the lens 7 and enters the image sensor 8, forms an image on a fine light-receiving element arranged in the sensor 8, is photoelectrically converted for each element, and the M product of charges is sent from the pulse generation circuit. The signals are scanned and transferred one by one and sequentially enter the signal processing circuit, where the signals are binarized into an image signal and a margin signal, band compressed (run length processing), and sent to the modulator 10, where the modulated wave is It is sent to the receiving section 2 through the transmission line 12, and the receiving paper 16
will be received. In addition to the solid-state imaging method used in this embodiment, there are various imaging methods, such as scanning the imaging tube with an electron beam, but in any case, the charges accumulated in each light receiving element are processed one by one through signal processing. There is no difference in the fact that it is sent to the circuit.

There are seven figures 17 and 18 on the sending paper 3 as shown in Figure 1.
．． 19, 20, 21, 22, and 23 are drawn, and the upper edge 24 and side edge 25 of the page parallel to the main and sub-scanning directions correspond to the upper edge and side edge of the effective scanning range. Two barcodes A, B and C, D are written by the sender at each location. Note that as long as the barcode can be recognized, the entry method may be a writing instrument, a rubber stamp, or any other method.

The location marked with each barcode is selected to transmit only a portion of the screen, in this example the shape 20 in the center of the screen, and a virtual Lines e', f, g, h
The figure 2 is placed in a rectangular section 26 partitioned by
0 is located.

On the other hand, for facsimile transmission ff1l, the image signals obtained by scanning each of the barcodes are processed as described below, and finally only the figure 20 in the section 26 is sent to the receiving unit.
A microprocessor 28 is incorporated which instructs the controller 9 and modulator 10 to transmit data.

In addition, the facsimile transmission ml has a switching mode between the "partial transmission mode", which transmits a part of the screen as described above, and the conventional "full transmission mode", which transmits the entire screen without marking a bar code. A changeover switch (not shown) is provided to perform this.

Next, the procedure for performing partial transmission using the method of the present invention and the operation of the facsimile transmitter 1 will be explained. A transmission paper 3 on which barcodes A, B, C, and D shown in FIG. 1 are written is inserted into the transmission section 1 so that the upper side 24 is scanned first.

Hereinafter, in order to facilitate understanding of the functions of the microprocessor, the related operations between the scanning line j and the bar code, which are modeled and shown in FIG. 1, will be explained.

First, barcode A on the left side of the top side is scanned (arrow)]
When the image signal is sent to the control unit 9, the microprocessor 28 reads this signal and issues two types of commands. The reading method at this time is to repeatedly scan the three parallel bars that make up the barcode several times and confirm that this figure is a meaningful figure for implementing the present invention. carried out by The first command is to skip all information written on the paper to the left of the vertical line C passing through the barcode A (margin signal processing), and to handle the information written on the right side as usual. This command is transmitted to the signal processing circuit. The second command is until it detects barcode C above the side edge of the paper that will be scanned in the future.
This command is transmitted to the control unit 9 to process margin signals for the paper surface of one or more horizontal lines passing through the barcode C.

According to the above command, any information such as figures 17 and 18 written above the horizontal line g passing through the bar code C on the upper side will not be transmitted.

Next, barcode B on the right side of the upper side is scanned [arrow k]
, is detected by the microprocessor 28, a command is transmitted from the microprocessor 28 to the signal processing circuit to process all information written on the right side of the vertical line f passing through this barcode B as a blank signal.

Next, the barcode C on the upper side is scanned (arrow 1)
, and when detected, the microprocessor 28 issues a command to the control section 9 to first detect the barcode A and cancel the second command.

Therefore, by superimposing the previous commands, transmission of the figure 20 near the center of the page will start.

Finally, when the barcode D below the side edge is detected, the microprocessor 28 instructs the control unit IO to perform margin signal processing on the paper surface below the horizontal line passing through the barcode D, and the modulator 10 Output the margin signal until the paper ends. Therefore, figures 22 and 23 are not transmitted.

To summarize the above operation, all information included above the horizontal line g, below h, to the left of vertical line C, and to the right of f is processed as a margin signal, and finally within the section 26 bordered by hatching. , that is, only the graphic 20 is transmitted. Therefore, the amount of signals required is small and the transmission time is shortened.

FIG. 4 shows a second embodiment of the invention. In this example, barcodes A and C are placed on the top and side of the sending paper, respectively.
In this example, only the information within the section 27 (shown by hatching) partitioned by the straight line c1g can be transmitted.

Further, although not illustrated here, three or more barcodes may be provided on each side, and any readable sill may be used in place of the barcode.

It should be noted that the present invention is not limited to the above-described embodiments; for example, the method of the present invention may be applied to other types of facsimile machines capable of compressing the band of margin signals. Of course, various changes can be made without departing from the above.

〔Effect of the invention〕

As described above, the present invention exhibits the following excellent effects.

(i) Since all areas other than the necessary portions of the paper defined by the marks written on the transmission paper are subjected to margin signal processing, the amount of transmitted signals is minimized, and therefore the transmission time can be shortened to the maximum.

a) In addition to the effect of item (i), where the preparation of the transmission paper is completed by simply filling in the mark, the communication cost of facsimile can be significantly reduced.
