The present invention relates to a method of performing recording paper cutting or cutting line printing through page division of recording paper when copying a document of a fax or printing a received document, and in particular, a page of an original exceeding a standardized paper size (such as A4 or B5). It relates to an automatic split method.

In the conventional facsimile, the paper is cut to the same length as the original when copying or receiving. Therefore, if the length of the original exceeds the standard size, the paper is not automatically cut and the recording paper is printed at the size desired by the user after receiving or copying. There is a problem in that cutting is difficult, and in automatic cutting, there is a problem in that continuous data (manuscript content) is cut off in the middle.

The present invention counts the number of lines being printed at the time of copying or receiving, and cuts or prints a cut line when the size is reached, and puts a swing margin to prevent data disconnection at the boundary of the size. It provides a method of dividing original pages of facsimile that is convenient for organizing documents exceeding the standard size and preventing data disconnection by performing cutting and cutting line print control according to whether continuous white line is detected. The division method of the present invention will be described with reference to FIG.

That is, according to the automatic document dividing method of the present invention, swing margin upper and lower limits A and C are set forward and backward on the basis of the dividing line B of the standard document size, and the current number of printed lines is set to the upper limit of the swing margin A. When it reaches the swing margin lower limit line (C), it is determined whether or not to detect all the back lines in successive lines. If a plurality of consecutive back lines are detected, the point is recognized as a dividing line. The page is divided after transferring the recording sheet by the margin interval F to the dividing line.

On the other hand, in the dividing method, the front-backline detection between the swing margin upper limit (A) and the lower limit (C) and page division according to the detection determine whether the cutter is on or off. A first process of determining whether the current line count is the upper limit A while counting the number; a second process of determining whether a plurality of consecutive back lines are detected from the subsequent lines if the current line count is the upper limit A; A third step of dividing the page after transfer of the recording sheet by a margin interval (F) when the back line is detected, and repeating the first step; and if the back line is not detected in the second step, the number of current lines after scanning or receiving one line is the lower limit. (C) If the front back line is not detected until the lower limit line (C) is detected, after transferring the recording sheet by the margin interval (F), the page is divided and the first step is repeated. Hereinafter, the page division process according to the present invention will be described with reference to FIGS. 1 to 3.

First, as shown in FIG. 2A, when copying or receiving and printing a continuous original 1 having a length exceeding a standard sheet (such as A4 or B5), the page division of the recording sheet 2 according to the present invention is performed. As shown in FIG. 2B, the page is divided by printing a cutting line within the range of size ± swing margin of the standard paper, or the page is divided by cutting as shown in FIG. 2C, depending on the cutter on or off setting.

On the other hand, the swing margin set in the present invention is the margin upper limit (A) and the lower limit (C) by a predetermined number of lines before and after the basis of the dividing line (B) of the standard paper, as shown in Figure 3a Is set and the number of lines of the upper and lower limit lines A and C is stored in advance.

In this case, the swing margin AC is used to prevent disconnection of continuous image information (= content of the original), and a plurality of consecutive all-back lines (black data is 1/4 of all 1-line data) in the swing margin AC. In the following cases, the number of lines for performing page division (printing of cut or cut lines) is arbitrarily set from detection or not.

In addition, if the number of consecutive back lines is detected as two lines on the basis of two lines as an embodiment, the spot is recognized as a dividing line. Referring to FIG. Explain.

First, enable the scanner and printer when copying an original, and enable only the printer when receiving an original.

Then, the cutter on / off which determines whether automatic document cutting is determined is discriminated.

As a result of the discrimination, in the case of the cutter-off, continuous printing is performed until the end of the image information or the end of the reception in the document without performing page division according to the present invention, and then cut or print the cut line. That is, one line scan (at the time of copying) or printing is received after reception, and the end or reception end of the image information is determined, and before the end, the operation of printing the line after one line scan or reception is repeated, and when the recording paper 2 is finished, Transfer the printed line to the divider by the margin interval (F), then cut or print the cut line, and finish by disabling the scanner and printer (print in the form shown in Figure 2a).

However, in the case of cutter on, the line counter is initialized (LINE = 0), one line is scanned or received, the line is printed, the number of lines is increased by +1, and it is determined whether the image information is terminated or the end of reception.

If the result of the discrimination is terminated, after the recording paper is transferred by the margin interval F, the cut or cut line is printed, and the scanner and the printer are disabled to finish.

However, if the determination result shows that image information or reception is continuous, it is determined whether the counted number of lines is the swing margin upper limit (A). If it is within the upper limit (A), one line of scan / receive / print / printer / end discrimination / upper limit (A) The process is repeated until the current number of lines reaches the upper limit A, and the printing per line of image information is continued.

Subsequently, when the current line count reaches the upper limit A, it is determined whether the black data of the image data of the current line is 1/4 or more of the entire one-line data.

In other words, if it detects whether all-back lines are detected (once) and prints after the next one-line scan or reception, and increases the number of lines by +1 to determine whether all-back lines are detected in the next line (two times). Since two consecutive back-back lines are detected, the point is recognized as a dividing line, and the recording sheet 2 is transferred by the margin interval F from the final print line to the dividing line, and then cut (Fig. 2c) or cut. Print the line (Figure 2b).

Since the page is divided (cut or cut line printing) in this manner, the line counter is initialized (LINE = 0), and the process is performed again, and a series of operations are repeated to scan image information of the next page, print, and determine the dividing line.

However, if two consecutive back lines are not detected after the current number of lines = A ?, one line is scanned or printed after reception, and the number of lines is increased while determining whether the current number of lines is the swing margin lower limit (C).

If the result of the discrimination is not the lower limit line (C), the process of determining whether the previous back line is detected until two consecutive all-back lines are detected, and if two consecutive all-back lines are detected before the current number of lines becomes the lower limit line (C), Recognize it as a dividing line, transfer the recording paper 2 by the margin interval F, and then cut or print the cut line, and then perform the process again from the initializing of the line counter (LINE = 0).

However, even if the current number of lines becomes the swing margin lower limit line (C), if two consecutive back lines are not detected, transfer the recording paper (2) by the margin interval (F), then cut or print the cut lines, and reset the line counter. Retry from step = 0).

By repeating the above series of steps until the end of the image information or the end of reception, the page division of the original within the range of ± swing margins (A, C) is automatically performed centering on the dividing line (B) of the standard paper. FIG. 3 illustrates a case where two consecutive back lines are detected between ABs and pages are divided, and FIG. 3C illustrates a case where two consecutive back lines are detected between BCs and a page is divided.

As described above, according to the present invention, the pages are automatically divided when copying a document exceeding the length of a standard sheet or printing after receiving, so that documents can be organized and stored, and data can be prevented from being broken. Therefore, there is an effect that can prevent the damage to the original content.
