Description

  The present invention relates to a facsimile machine, and more particularly to a facsimile machine capable of performing duplex printing when printing received data and stored data.

  In the facsimile apparatus (FAX), as the printing method of the received data and the accumulated data as image data, there are double-sided printing and divided printing in addition to normal printing. Normal printing is a printing method in which image data is printed on paper of these standard sizes when the paper size to be handled is a standard size such as A4 or B4. Double-sided printing is a printing method that prints not only on the front side of printing paper but also on the back side when printing image data. Further, the division printing is a printing method in which long image data is divided and printed on a standard size paper when the size of the paper to be handled is not a standard size but a long size such as a roll paper.

  As for the facsimile apparatus that performs printing using such a printing method, there are the following techniques disclosed before the present application.

  Japanese Patent Laid-Open No. 2004-228561 performs a copy process or a FAX transmission process, and simultaneously prints job information such as double-sided printing and divided print mode information attached to image data for each job as information necessary for the process together with the image data as a file A technique for realizing advanced file search by filed in a file is proposed.

  Further, in Patent Document 2, document information of a plurality of pages is extracted from stored document information, and the size of the page at the time of printing is compared for each page of the extracted document information. In other words, a technique has been proposed in which double-sided printing can be performed even when the page sizes are not uniform, by detecting the size of the paper and printing on the paper of the detected paper size by double-sided printing.

  When performing divided printing, it is a common practice to add an “overwrite area” to the printed material in order to make the printed material that has been divided printed easier to see later and to prevent missing images in the divided portions. The overwriting area is an area where printing is performed when printing is performed in the first area of a page that follows the area (area) of about 1 cm at the rear end of the preceding page in a divided printed matter. is there.

The divided printing and overwriting area will be described with reference to FIGS. FIG. 4A shows an example of long-size image data. When printing such long-sized image data, the FAX performs printing by dividing using a standard-size sheet. (B) and (C) of FIG. 4 show the (A) divided and printed on a standard size sheet. The portion above the dotted line in (C) corresponds to the overwriting area, and a certain area at the rear end of the preceding (B) is printed in the overwriting area in (C). Thus, the presence of the overwriting area makes it easy to see the continuous divided printed matter and prevent image loss at the divided portion. FIG. 5 shows the original image data restored by superimposing (B) and (C). Since there is an overwriting area in this manner, adjustment when data is restored by superimposing the output originals (B) and (C) is facilitated.

  Divided printing can be effective even when performing duplex printing basically. Referring to FIG. 4 shown above, (B) and (C) are printed on the front and back surfaces of the same sheet. However, if division printing is performed in the double-sided printing format, the front and back surfaces of the same sheet cannot be overlaid, so the value of adding an overwriting area is reduced.

  For example, when printing A3 size image data on both sides of an A4 size paper, the A3 size is usually 297 × 420 (mm) and the A4 size is 210 × 297 (mm). And A3 size image data can be developed on the front and back surfaces of A4 size paper without scaling. However, if an overwriting area is added, the image data protrudes by the area occupied by the overwriting area. In such a case, each page may be printed with a somewhat reduced size in the sub-scanning direction. However, it is desirable to print the received data at the same reduction ratio as the sent data. It is not preferable to execute the processing.

  The present invention has been made in view of the above-described problems, and when double-sided printing processing is set at the time of divided printing of image data received by FAX, the image is controlled so as not to add an overwriting area. An object of the present invention is to provide a facsimile machine that executes data printing processing.

The present invention provides document information input means for performing document information receiving operation and document information reading operation, storage means for storing the document information input by the document input means, and the document stored in the storage means. A compression / expansion unit that compresses / decompresses information, a printing unit that prints the document information that is compressed / decompressed by the compression / decompression unit, and whether or not to execute double-sided printing and division printing by the printing unit are set. A printing process setting unit; a printing process control unit that controls the printing process of the duplex printing and the divided printing by the printing unit; and the printing process of the divided printing when the printing process of the divided printing is executed. the area of the rear end of the page to be among the preceding, an area adding means for performing area additional control to be added to the beginning of the area of the page to add row, measuring the size of the document information A measuring means for performing, when printing of the document information, and a size changing means for changing the size of the document information output, when the printing process of the divided printing is performed by the print processing controller, If it is determined by the print processing setting means that double-sided printing is set, the area adding means does not execute the area adding control, and the measuring means includes the page-divided document information. The size of the page to be followed is measured, and if the size of the follow page measured by the measuring unit is equal to or smaller than a predetermined size, the size changing unit reduces the size of the output document information. In the case where the reduction control is executed, and the print processing control unit executes the divided print processing, double-sided printing is not set by the print processing setting unit. If it is determined from the area adding means is a facsimile apparatus and executes the area addition control.

According to the present invention, in the above invention, the facsimile apparatus further includes a control method setting unit, and the control method setting unit sets whether or not to execute at least one of the area addition control and the reduction control. Can be characterized.

According to the present invention, when double-sided printing processing is set during divided printing of image data received by FAX, control is performed so as not to add an overwriting area. Therefore, an unnecessary overwriting area is not added during double-sided printing. It is possible to eliminate waste in document printing. In addition, as a secondary effect, since unnecessary image reduction performed when a region is added is not performed, a printed matter with the original image data can be obtained. Further, when double-sided printing is set at the time of executing divided printing, if the image data to be followed is equal to or smaller than a predetermined size among the divided image data, the entire image data is reduced in the sub-scanning direction. Print to fit on one side of the paper. Thereby, since execution of divided printing is avoided, it is possible to avoid the problem that it is difficult to see the printed matter.

  With reference to FIG. 1, the configuration of a facsimile apparatus according to an embodiment of the present invention will be described. The facsimile apparatus 10 includes a scanner unit 11, a printer / plotter unit 12, a compressed data storage memory 13, an image data decompression unit 14, a decompressed data expansion memory 15, a modem / NCU unit 16, and a compressed data storage buffer 17. An image data compression unit 18, a system control unit 19, and a control panel 20.

  The scanner unit 11 performs a document reading operation and reads image data with a predetermined resolution from a document image. The printer / plotter unit 12 prints and prints the received data and outputs the image data to a sheet.

  The compressed data storage memory 13 accumulates received files and image data compressed by the image data compression unit 18. The image data decompression unit 14 decompresses the compressed image data stored in the compressed data storage memory 13 to the original image data size. The decompression data decompression memory 15 decompresses the image data decompressed by the image data decompression unit 14 in units of pages.

  The modem / NCU unit 16 modulates and demodulates and transmits the image data, and transmits various procedure signals in the transmission control procedure. The compressed data storage buffer 17 is a buffer that temporarily stores image data when the image data compression unit 18 or the image data decompression unit 14 compresses or decompresses the image data. The image data compression unit 18 compresses image data read by the scanner unit 11 and can also compress received image data.

  The system control unit 19 includes a CPU, a ROM, a RAM, and the like, and controls the components in the facsimile apparatus 10 to realize a predetermined operation of the facsimile apparatus 10. The control panel 20 includes an operation panel that accepts an instruction from the user and an input of information, and a display window that informs the usage status of the facsimile apparatus 10. Information is input / output to / from the user. Various settings of the facsimile apparatus 10 are also made from the control panel 20, and the width of the overwriting area can also be set.

  The facsimile machine 10 is controlled based on a program stored in the system control unit 19. The image data received by the modem / NCU unit 16 is compressed by the image data compression unit 18 and stored as compressed data in the compressed data storage memory 13 and the compressed data storage buffer 17. The image data stored in the compressed data storage memory 13 is decompressed by the image data decompression unit 14 and output from the printer / plotter unit 12. When duplex printing is performed, the system control unit 19 controls the printer / plotter unit 12 to execute duplex printing.

  When divided printing is executed, the decompressed image data is stored in the decompressed data decompression memory 15, and the overwritten image is stored in the overlay area based on the image data on the decompressed data decompression memory 15. Is output.

  Next, internal control of the facsimile apparatus in the first embodiment will be described. The facsimile apparatus according to the present embodiment performs control so that an overwritten area is not added to an output document when double-sided printing processing is set when split printing is performed.

  FIG. 2 is a flowchart showing the internal control of the facsimile apparatus of this embodiment. This flow control is controlled by the system control unit 19 in the facsimile apparatus 10.

  When the printing process is started in the facsimile machine 10 (S101), the data size is measured for each image data to be printed (S102). If the measured image data size is equal to or smaller than the paper size of the output paper, normal printing is executed. If the measured image data size is larger than the paper size of the output paper, split printing is executed. The

  As described above, the overwriting area is added during the division printing process. Therefore, if the divisional printing is not executed as a result of the measurement of the image data size (S103 / No), the printing process is executed without adding the overwriting area regardless of the setting state of the double-sided printing (S105, S107). .

  As a result of measuring the image data size, when divided printing is executed (S103 / Yes), when double-sided printing is not set as the printing method (S104 / No), an overwriting area is added (S106), Printing processing is performed (S107). On the other hand, when double-sided printing is set as the printing method (S104 / Yes), the system control unit 19 of the facsimile apparatus 10 performs the printing process without adding the overwriting area that is added during the normal divided printing process. (S105, S107).

  When the printing process is performed (S107) and the printing process of the image data is completed, it is checked whether there is another image data to be printed in the print file including the image data (S108). If there is other image data to be printed (S108 / Yes), the process returns to S102 and the above flow is repeated. If there is no other image data to be printed (S108 / No), printing ends and the printing process is terminated (S109).

  According to the present embodiment, the facsimile apparatus 10 performs control so as not to add an overwriting area when double-sided printing processing is set during divided printing of image data received by FAX. Therefore, an unnecessary overwriting area is not added at the time of double-sided printing, and it is possible to eliminate waste in document printing. In addition, as a secondary effect, since unnecessary image reduction performed when a region is added is not performed, a printed matter with the original image data can be obtained.

  Next, a second embodiment will be described. The facsimile apparatus according to the present embodiment performs sub-scanning on the entire image data when the double-sided printing processing is set at the time of the divided printing and the image data to be followed is less than a certain size among the divided image data. It is adjusted so that it can be accommodated on one side of the sheet by reducing in the direction, and control is performed so as not to perform divided printing.

  FIG. 3 is a flowchart showing internal control of the facsimile apparatus of this embodiment. This flow control is controlled by the system control unit 19 in the facsimile apparatus 10.

  When the printing process is started in the facsimile machine 10 (S201), the data size is measured for each image data to be printed (S202). If the measured image data size is equal to or smaller than the paper size of the output paper, normal printing is executed. If the measured image data size is larger than the paper size of the output paper, split printing is executed. The

  As described above, the overwriting area is added during the division printing process. Therefore, if the division printing is not executed as a result of the measurement of the image data size (S203 / No), the printing process is executed without adding the overwriting area regardless of the setting state of the duplex printing (S206, S209). .

  As a result of the measurement of the image data size, when performing divided printing (S203 / Yes), if double-sided printing is not set as the printing method (S204 / No), an overwriting area is added and printing processing is performed. It performs (S208, S209).

  On the other hand, when double-sided printing is set as the printing method (S204 / Yes), the system control unit 19 of the facsimile apparatus 10 measures the size of the image data to be followed out of the divided image data (S205). . As a result of the measurement, when the image data to be followed is equal to or smaller than the predetermined size (S205 / Yes), the entire image data is arranged in the sub-scanning direction so that it can be fit on one side of the sheet without performing the division process and the addition of the overwriting area. The image is reduced and printed (S207, S209). On the other hand, if the measurement result does not fit in the predetermined size (S205 / No), similarly to S105 of the first embodiment, the printing process is performed without adding the overwriting area (S206, S209). )

  In this reduction processing, if the sub-scanning direction reduction processing is performed for any image data size without limiting by the size of the image data to be followed, in some cases, the output printed matter may be There is a possibility that the image is flattened that has been reduced more than necessary in the sub-scanning direction. In such a case, it is better not to perform the sub-scanning direction reduction process. Therefore, the facsimile apparatus 10 according to the present embodiment determines whether or not to reduce the sub-scanning direction depending on the size of the image data to be followed. In addition, the condition of the image data size to be followed, in other words, the reduction ratio when reducing in the sub-scanning direction is preset in the system control unit 19 of the facsimile apparatus 10 as a default. The user can change the condition setting. This setting change is performed from the control panel 19.

  When the printing process is performed (S209) and the printing process of the image data is completed, it is checked whether there is another image data to be printed in the print file including the image data (S210). If there is other image data to be printed (S210 / Yes), the process returns to S202 and the above flow is repeated. If there is no other image data to be printed (S210 / No), printing ends and the printing process is terminated (S211).

  According to the present embodiment, when double-sided printing is set at the time of executing divided printing, if the image data to be followed is equal to or smaller than a predetermined size among the divided image data, the entire image data is sub-scanned. The image is reduced so that it fits on one side of the paper. Thereby, since execution of divided printing is avoided, it is possible to avoid the problem that it is difficult to see the printed matter.

  Next, a third embodiment will be described. The facsimile apparatus 10 according to the present embodiment is the same as the facsimile apparatus according to the second embodiment except that printing control and image data that do not add an overwriting area when double-sided printing is set at the time of performing division printing are performed in the sub-scanning direction. It is possible to set whether or not to execute the print control to be reduced to each. This print control setting is set by inputting to the system control unit 19 from the control panel 20 of the facsimile apparatus 10. According to the present embodiment, since the user can set the print control mode, it is possible to contribute to the convenience of the user.
