Description

An information processing device that encodes manuscript data to generate a coded image, an image forming device that decodes a coded image on a paper manuscript read by a manuscript reader and executes printing, and a series of these processes. Regarding the printing method to be executed.

For printing machines used offline in places such as schools where the network is not complete, the coded image generated by encoding the manuscript data is once printed on paper media with a printer at hand, and then used as an offline printing machine. There is known a technique (hereinafter referred to as "paper interface function") in which a coded image on a paper medium is read and original data can be restored from the coded image and printed. With this technology, offline printing is possible without degrading the quality of the original manuscript data, and even if the paper medium is left on the printing press, the encoded image cannot be read directly, so offline printing that is safe for security is possible. It will be possible.

In the above-mentioned paper interface function, when coding the manuscript data, if the manuscript data is high resolution data, the coded image also becomes large size data, so that the paper of a specific size (for example, A4 size) is used. It is expected that it will not fit. In such a case, it is conceivable to divide and print the coded image on a plurality of pages of paper, but the user needs how many pages of paper medium for plate making of one manuscript data. There is a problem that it is difficult to understand and it is not easy to use in the printing operation on a printing machine.

Conventionally, the original is read and the image data binarized by encoding is encrypted, the encrypted image data is divided into a plurality of parts, and an identifier is generated for each divided image data to output an encrypted document. (For example, Patent Document 1).

The data area is an area composed of a code data area AR2 and a margin area AR3 which is a printable area (printable area) other than the area where the image of the two-dimensional code is printed. In the example of FIG. 4, there is a margin portion between the positioning markers MK, but data may be stored in this portion as well. As a specific method for generating the coded image, for example, the technique disclosed in "Japanese Unexamined Patent Publication No. 2015-011573" can be adopted.

The operation of the embodiment having the above configuration will be described. FIG. 5 is an operation explanatory view of this embodiment.

First, in the information processing apparatus of FIG. 2, the coded image generated by the coded image generation unit 212 in the control unit 201 has the same data format as the example of the divided coded image shown in FIG. In this case, if the size required when the coded image is printed on the paper medium does not exceed the size of the paper medium, for example, A4 size, the coded image is directly passed through the second printer driver unit 214 in FIG. The printing device 103 prints on a paper medium. On the other hand, the divided coded image generation unit 213 is a coded image generation unit 212 so that when the size required when the coded image is printed on the paper medium exceeds the size of the paper medium, each of them fits in the size of the paper medium. The coded image generated by is divided into a multi-page divided coded image.

When the size required when the coded image is printed on the paper medium exceeds the size of the paper medium as described above, the divided coded image generation unit 213 determines the margin area of each divided coded image illustrated in FIG. By adjusting AR3, it is possible to control each divided coded image so that it fits in the size of the paper medium. For example, as shown in FIG. 5A, the last line of the manuscript data (“OPQRSTU” in the figure) in the coded image area 501 indicated by the broken line corresponding to the manuscript data area is displayed. Consider a case where the area corresponding to the line) does not fit in the printable area 500 of the paper medium shown by the solid line and extends beyond the printable area 500. In this case, the divided coded image generation unit 213 narrows the margin area AR3 illustrated in FIG. 4 so that the entire area 501 of the coded image indicated by the broken line corresponding to the area of the original data is a paper medium. It is controlled so that it fits as the divided coded image 502 within the size of.

By controlling the margins as described above, it is possible to control the entire region of the coded image corresponding to the document data so as to fit as a divided coded image on one sheet of paper, and the multifunction device 102 can control the platen 304. It is possible to reduce the number of times the paper medium is read by operating.

Further, when the size required when the coded image is printed on the paper medium exceeds the size of the paper medium as described above, the divided coded image generation unit 213 is arbitrarily adjacent to the plurality of divided coded images. In the combination of the first divided coded image and the second divided coded image that follows, the data located near the end of the first divided coded image is moved to the beginning of the second divided coded image. Therefore, each divided coded image can be controlled so as to fit in the size of the paper medium. For example, as shown in FIG. 5B, the area 501 of the coded image indicated by the broken line corresponding to the area of the original data does not fit in the printable area 500 of the paper medium indicated by the solid line, and the English of the original data. The region of the coded image corresponding to the first line (the line displayed as "ABCDEFG" in the figure) of the document is included in the first divided coded image 503 (# 1), and the English document of the manuscript data. It is assumed that the second divided coded image 503 (# 2) includes the area and subsequent areas of the coded image corresponding to the second line (the line displayed as "HIJKLMN" in the figure). In this case, the divided coded image generation unit 213 encodes the coded image data corresponding to the first line (the line displayed as "ABCDEFG" in the figure) of the English document of the manuscript data into the second divided coded image. Control is performed to move the image 502 (# 2) to the beginning. As a result, the end of the Japanese document of the manuscript data (the line displayed as "aiueokaki" in the figure) and the first line of the English document of the manuscript data (the line displayed as "ABCDEFG" in the figure). The space (the part of the alternate long and short dash line in the figure) is adjusted so as to be the boundary between the first divided coded image 503 (# 1) and the second divided coded image 503 (# 2).

By controlling the page breaks as described above, the region 501 (broken line) of the coded image is divided into the first split coded image 503 (# 1) and the second split coded image in the meaningful breaks in the manuscript data. It is possible to divide into 503 (# 2), and when operating the platen 304 on the multifunction device 102 to read a plurality of divided coded images, it is possible to intuitively grasp how far the reading has been performed. It becomes possible.

Further, when the size required when the coded image is printed on the paper medium exceeds the size of the paper medium as described above, the divided coded image generation unit 213 encodes the image data portion in the original data. It is possible to control the image and the coded image corresponding to the character data portion in the manuscript data so as to be divided into different divided coded images. For example, as shown in FIG. 5 (c), paper shown by a solid line from the middle of the region corresponding to the character data of the manuscript data in the coded image region 501 indicated by the broken line corresponding to the region of the manuscript data. Consider a case where the printable area 500 of the medium does not fit in the printable area 500 and extends beyond the printable area 500. In this case, the divided coded image generation unit 213 is used between the coded image corresponding to the image data portion in the manuscript data and the coded image corresponding to the character data portion in the manuscript data (of the one-point chain line in the figure). The portion) is adjusted so as to be the boundary between the first divided coded image 504 (# 1) and the second divided coded image 504 (# 2).

By controlling the page division by the image data and the character data as described above, the region 501 (broken line) of the coded image is divided into the first divided coded image 504 (# 1) and the first division coded image 504 (# 1) in the meaningful division in the manuscript data. It is possible to divide into 2 divided coded images 504 (# 2), and when the compound machine 102 operates the platen 304 to read a plurality of divided coded images, how far has the reading been performed? Can be grasped intuitively.

In the above control operation, the division-encoded image generation unit 213 has page number information indicating the number of divisions of the division-encoded image from the encoded image and encoding in each header area of the division-encoded image. Area information (for example, data size) indicating the range of the divided coded image in the image may be added. On the other hand, each time the image area determination unit 312 in the control unit 301 of the composite machine 102 of FIG. 3 decodes the decoded data from the divided coded image in the paper medium, the page number information included in the decoded data And, based on the area information, the image area to be printed is determined.

Assuming that the above-mentioned page number information and area information are passed from the information terminal device 101 to the multifunction device 102, the user makes a mistake in the order of reading the divided coded images on the paper medium on the platen 304 of the multifunction device 102. However, it is possible to determine the image area of the printed image corresponding to the original data in the correct order.

Further, the liquid crystal display device of the operation panel 305 of the multifunction device 102 of FIG. 3 has a divided coded image that is insufficient for plate making printing based on the page number information included in the header information in the decoded data. Information about the number of pages is displayed.

As a result, the user can grasp the shortage of the number of pages in the operation of reading the divided coded image of the paper medium on the multifunction device 102, and can prevent the leakage of the read data.

FIG. 6 is a flowchart showing an example of control processing executed by the control unit 201 of the information terminal device 101 having the configuration example of FIG. This control process may be realized as a collaborative operation of a dedicated hardware device that realizes the functions of each of 210 to 214 in the control unit 201, or the processor of the control unit 201 stores it in a memory (not particularly shown). It may be realized as an operation of executing the controlled control program. In the explanation of the flowchart of FIG. 6 below, each part of FIG. 2 shall be referred to at any time.

The user of the information terminal device 101 specifies a printer driver corresponding to the first printer driver unit from the application executed by the document data generation unit 210, and executes a print command.

When printing is executed, the process illustrated in the flowchart of FIG. 6 is started, and first, the print data generation unit 211 generates print data which is a print image from the original data generated by the original data generation unit 210. (Step S601).

Next, the coded image generation unit 212 generates a coded image from the print data generated in step S601 (step S602).

Next, the divided coded image generation unit 213 determines whether or not the coded image generated in step S602 fits within one page when printed on a paper medium (step S603).

If the determination in step S603 is YES, the divided coded image generation unit 213 outputs the coded image generated in step S602 as one divided coded image, and proceeds to the process of step S609 described later.

If the determination in step S603 is NO, the divided coded image generation unit 213 determines whether or not paper saving is possible by adjusting the margins when printing the encoded image on a paper medium (step S604). Specifically, the divided coded image generation unit 213 reduces the margin area AR3 of the coded image illustrated in FIG. 4 so that the data of the coded image protruding from the size of the paper medium is stored in the paper medium. Determine if it fits within one page.

If the determination in step S604 is YES, the divided coded image generation unit 213 adjusts the margins so that the coded image fits within one page of the paper medium (step S605). After that, the divided coded image generation unit 213 outputs the coded image with the adjusted margins as one divided coded image, and proceeds to the process of step S609 described later.

If the determination in step S604 is NO, the divided coded image generation unit 213 divides the coded image data into a plurality of divided coded images so as to fit on each page of the paper medium (step S606).

Subsequently, the divided coded image generation unit 213 determines whether or not the page switching portion of each divided coded image generated in step S606 is a break in the image (step S607). Here, the image breaks are breaks in different types of languages as illustrated in FIG. 5 (b), breaks in image data and character data as illustrated in FIG. 5 (c), and other, for example, text data. Paragraphs, page breaks, etc.

If the determination in step S607 is YES, the divided coded image generation unit 213 outputs a plurality of divided coded images generated in step S606, and proceeds to the process of step S609 described later.

If the determination in step S607 is NO, the divided coded image generation unit 213 adjusts so that the page switching portion of each divided coded image generated in step S606 becomes an image break (step S608). .. This adjustment process is, for example, the process described with reference to FIG. 5 (b) or FIG. 5 (c) described above. After that, the divided coded image generation unit 213 outputs each divided coded image after adjustment, and proceeds to the process of step S609.

In step S609, the first printer driver unit activates the second printer driver unit 214 corresponding to the printing device 103 of FIG. 1 preset in the first printer driver unit. The second printer driver unit 214 is one or more divided coded images (1) delivered from the first printer driver unit to the printing device 103 connected to the information terminal device 101 via the network 104 of FIG. Instruct printing of (including sheet coded images). After that, the control unit 201 ends the control process shown in the flowchart of FIG.

FIG. 7 is a flowchart showing an example of control processing executed by the control unit 301 of the multifunction device 102 having the configuration example of FIG. This control process may be realized as a collaborative operation of a dedicated hardware device that realizes the functions of each of 310 to 313 in the control unit 301, or the processor of the control unit 301 stores in a memory (not particularly shown). It may be realized as an operation of executing the controlled control program. In the following description of the flowchart of FIG. 7, each part of FIG. 3 shall be referred to at any time.

First, the user of the multifunction device 102 sequentially sets one or more sheets of paper media exemplified in FIG. 4 printed by the printing device 103 according to the instruction from the information terminal device 101 of FIG. 1 on the platen 304 ( Step S701).

Next, the user of the multifunction device 102 presses the read button on the operation panel 305. As a result, the reading unit 310 in the control unit 301 controls the image reading unit (not particularly shown) arranged in the lower part of the platen 304, thereby printing on the paper medium set on the platen 304. The coded image is scanned and read (step S702).

When the reading operation in step S702 is completed, the decoding unit 311 in the control unit 301 decodes the decoding data (print data) and the header information from the divided coded image read by the reading unit 310. At this time, the decoding unit 311 detects the four positioning markers MK illustrated in FIG. 4 to determine the data read area. Next, the decoding unit 311 reads the header information recorded in the first fixed byte range of the divided coded image from the determined data reading area. Further, the decoding unit 311 reads the decoded data for the total number of bytes of data included in the header information from the data area of the divided coded image following the header information. As a result, the decoding unit 311 reads the data of the original data area AR1 illustrated in FIG. 4 and the data of the error correction code data area AR2 in which the data of the error correction code is stored, and the error of the error correction code data area AR2. The decoded data in the original data area AR1 is decoded while performing error correction processing using the correction code (above, step S703).

Next, the image area determination unit 312 in the control unit 30 determines the image area to be printed with respect to the decoded data decoded in step S703 based on the page number information and the area information included in the decoded data. (Step S704).

Subsequently, the image area determination unit 312 in the control unit 301 performs decoding processing and an image area for all the divided coded images printed on all the paper media divided from the coded image in the information terminal device 101. Is completed, and it is determined whether or not all the decrypted data necessary for plate making are prepared (step S705).

If the determination in step S705 is NO, the control unit 301 tells the liquid crystal display device of the operation panel 305 that operates as the notification unit based on the page number information included in the header information in the decoded data decoded in step S703. Information on the number of pages of the divided coded image, which is insufficient for plate making printing, is displayed (step S706). After that, the control unit 30 returns to the process of step S701, shifts to the next paper medium reading process, and repeatedly executes the series of processes from steps S701 to S706 described above.

As a result of the iterative processing, when all the decoding data required for plate making are collected and the determination in step S705 is YES, the print execution unit 313 in the control unit 301 is generated by a series of iterative processing from steps S701 to S706. Based on the decoded data corresponding to the encoded image, image data for plate making printing is generated, output to the printer engine 302, and plate making printing is started (step S707). After that, the control unit 301 ends the control process shown in the flowchart of FIG. 7.

In the embodiment described above, plate-making printing is executed after all the decoding data necessary for plate-making is prepared in the multifunction device 102, but trial printing may be executed when some of the decoding data are prepared.

In the embodiment described above, the print data generated by the print data generation unit 211 in the control unit 201 of the information terminal device 101 of FIG. 2 is image image data with respect to the original data. The print data is, for example, the multifunction device 102. The data may be written in a printer language that can be analyzed.
