Detailed Description of the Invention [Industrial applications]

The present invention is capable of printing long originals that cannot be printed with a single sheet of cut paper.
The present invention relates to a facsimile device that divides and prints on a plurality of cut sheets.

[Prior art]

FIG. 5 is a block connection diagram showing a conventional facsimile apparatus disclosed in, for example, Japanese Patent Application Laid-Open No. 61-210765. In the figure, 9 is a main control section using a microcomputer, and 2 is a line with a partner machine. A line connection section for connecting the data, 10 a data processing section, 4 a recording section for printing using a cut sheet, and 5 an image information to be read and transmitted when a facsimile apparatus is used as a transmitter. A reading unit for obtaining, 11 is a pattern generating circuit for overlapping a part of an image of a long original and generating a signal for printing information indicating that overwriting is performed on a cut sheet, 12 is line data Is a random access memory (RAM) that stores Next, the operation will be described. First, when a line is connected to the partner machine, the data obtained by the line connection unit 2 through this line is that the main control unit 9 is a long document 13 as shown in FIG. 6 (a). If it is determined that the images are partially overlapped, the cut sheets 14 and 15 as shown in FIG. 6B are overwritten. Therefore, the main control unit 9 is a data processing unit.
Data for the number of overwriting lines accumulated in the random access memory 12 via 10 is recorded through the recording unit 4 at the head of the cut sheet of the next page. Further, after the overwriting is performed in this way, the main control section 9 uses the pattern generating circuit 11 to generate a linear signal, which is used as the information indicating the overwriting portion as shown in FIG. 6 (b). As the number 16, the recording unit 4 prints on the cut paper 15. As described above, according to the conventional technique, when the main control unit 9 determines that the long original 13, the long original 13 is always printed on a plurality of cut sheets 14 and 15. Therefore, when the portion B of the long original 13 as shown in FIG. 6 (a) is composed of only white data, the cut paper 15 out of the two printed cut papers 14 and 15 is completely white. As a result, a blank sheet is printed and discharged.

[Problems to be Solved by the Invention]

Since the conventional facsimile apparatus is configured as described above, when the long original 13 is divided into a plurality of cut sheets 14 and 15 to be printed, even if the image information of the final page is all white, it is printed. There is a problem that the mode is set, and as a result, all-white recording paper is unnecessarily discharged. The present invention has been made to solve the above problems, and when a long original is divided into a plurality of pages and printed,
An object of the present invention is to obtain a facsimile apparatus that controls the recording unit so that the final page is not printed and the wasteful blank paper is not ejected when the image information of the final page is all white.

[Means for Solving the Problems]

In the facsimile apparatus according to the present invention, the processing unit determines whether the line data stored in the page memory is all white, receives a long original, and divides it into a plurality of cut sheets for printing. At this time, based on the above judgment result, if each line data of the final page is all white, the main controller cuts off the image information of the final page.

[Action]

The main control unit in this invention, when the long original stored in the page memory is divided and printed on a plurality of cut sheets, and the image information of the final page is composed only of all white line data, the data processing unit Only if determined by
The last page is not printed to prevent wasteful blank paper discharge.

Examples of the invention

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main control unit having a function of truncating the last page when the image information of the last page is all white when a long original is divided and printed on a plurality of pages. A data processing unit for determining whether or not it is "white", 7 is a random access memory (RA
M) and 6 are pattern generation circuits necessary for printing information for making it possible to see from the cut sheet that the above-mentioned overwriting or truncation has been performed. In addition, the same components as those shown in FIG. 4 are denoted by the same reference numerals, and duplicate description thereof will be omitted. Next, the operation will be described. First, in the facsimile apparatus configured as described above, the data processing unit 3 detects whether or not the data stored in the page memory 7 is "white" according to an instruction from the main control unit 1. Main controller 1 is the second
When the long original 13 shown in the figure is divided and printed on a plurality of cut sheets 14, the data processing unit 3 determines whether or not the last page is all white. The page printing is stopped, and the pattern generation circuit 6 outputs the information 8 indicating that the image information has been truncated at the rear end of the previous page, in this case, a signal for printing a broken line. FIG. 2 shows that when the long original 13 is received and dividedly printed on a plurality of cut sheets 14, when the last page is all white, the last page is not printed and the information 8 indicating the final page truncation is displayed. It is explanatory drawing which imitates and shows the state added and printed to the previous page. Since the facsimile device also has a function of overwriting a part of the image information when the long original 13 is printed on a plurality of cut sheets 14, as described above, the pattern generating circuit 6 is used.
It is more convenient to generate and print the information indicating the truncation of image information and the information indicating that overwriting has been performed in different patterns. The pattern generation circuit 6 may be a character generator that generates data recorded at the source at the beginning of image information when transmitting, when a facsimile machine is used as a transmitter. FIG. 3 is a flow chart showing an example of the control operation in the case where the final page image information is truncated or overwritten and the information indicating that is printed as described above. The program shown in this flow chart is the main control unit. 1 is stored in advance in the program storage unit of the microcomputer that constitutes the computer 1. If the number of lines of the long original 13 received by the facsimile apparatus is x as shown in FIG. 4, this value is obtained by counting at the time of reception. Further, when the number of lines of the cut paper 14 is m, this value is a fixed value, and therefore it can be held in the program as a conversion table according to the size of each cut paper 14. In addition, the line for overwriting is n (n <m),
L (l <m) as a permissible value for judging as long original 13
Can also be read by the respective programs. Then, as a control method for preventing wasteful discharge of blank sheets,
Two counters for counting the number of each line are used.
One is a counter for the number of remaining accumulated data lines, which is 0a.
It is a variable in the range of x and the other is a counter for the number of remaining lines b, which is a variable in the range of 0bm. Therefore, in the case of the long original 13, since m <x, a = x and b = m are set as initial values. Next, the control operation will be described with reference to the flowchart of FIG. First, it is determined whether or not the accumulated data in the page memory 7 is completed (step ST1). If not, it is determined whether or not the remaining line number b is equal to n (step ST2), and is equal. In this case, the memory address at that time is stored in the overwriting pointer (step ST3). Next, it is determined whether the number of remaining lines b is zero, that is, whether the recording paper is finished (step ST4), and if it is not finished, the 1-line data from the memory address is transferred to the recording unit 4 (step ST4). ST5). Even if the number of remaining lines b is not equal to n in step ST2, the processes of step ST4 and thereafter are executed. Next, the image information is recorded line by line in the recording unit 4
Is printed (step ST6), the remaining accumulated data line number a and the remaining line number b are each decremented by 1 (steps ST7 and ST8), and the next line data address is used as a memory address (step ST9). That is, if there is no data accumulated in the memory, the process ends in step ST1. If b = n, that is, if the number of remaining lines b becomes the number of overwriting lines n, the memory address at that time is stored in the overwriting pointer in step ST3. Further, if b = 0, that is, if the recording paper is finished, the process of step 10 is started from step ST4, and it is determined here whether am, that is, the next page is the last page. If it is determined that it is not the final page here,
In order to perform normal overwriting, the process proceeds to step ST16. On the other hand, if it is determined in step ST10 that the image is the final page, whether or not the image information of the final page stored in the page memory 7 is all white is searched through the data processing unit 3 (step ST11). As a result, if all are white, the image information of the final page is cut off, the pattern generation circuit 6 prints a predetermined pattern, that is, information indicating the cutoff, and the process ends (steps ST13 and ST14). If it is determined in step ST11 that all are not white, it is determined whether bl, that is, the long original 13 is to be printed on the cut sheet 14 of the next page (step ST12). Where bl
If not, it is also truncated and the process proceeds to step ST13. On the other hand, if it is bl, information indicating overwriting is generated, this is printed (steps 16 and 17), the next page is pulled in (step ST18), and is stored in the overwriting pointer for overwriting. The set address is reset to the memory address (step ST19). And step ST20, S
At T21, the number of remaining lines b and the number of remaining accumulated data lines a are reset. In that method, the number of accumulated data lines before resetting is a
(Old), a = a (Old) + n by. Then, the process returns to step ST5 to continue recording. In this way, when printing the long original 13 in the facsimile machine using the cut paper 14, if the last page is all white, the image information is discarded without printing, and the information indicating that is also printed. As a result, the receiver can clearly know that the final page has been truncated without discharging a blank white sheet on the final page. In the above embodiment, the case of the recording control of the facsimile apparatus using the cut sheet 14 has been described, but it may be the transmission control in the case of transmitting the data in the memory, and the same effect as the above embodiment can be obtained. .

【The invention's effect】

As described above, according to the present invention, when a long original is divided and printed on a plurality of cut sheets, when the data processing unit determines that the final page is all-white data, the main control unit causes the recording unit Since it is configured to cancel printing of the last page, it is possible to eliminate wasteful blank paper discharge, and thus it is possible to save the recording paper, and it is reported that the image information has been truncated. Is printed on the page, so that there is an effect that the cutoff can be obtained at a glance for the user. Further, by sharing the generation of the pattern indicating the truncation of the image information with the portion that conventionally generates the source record data,
It is possible to realize generation of a pattern indicating truncation of image information with a minimum increase in hardware.
