  The image forming apparatus 300 is an electrophotographic printer and is a general-purpose image forming apparatus. The image forming apparatus 300 has a function of forming an image on a recording medium under the control of the PC 200. The image forming apparatus 300 is not limited to an apparatus that forms an image by an electrophotographic method, and may be an apparatus that employs another method such as an ink jet method.

  The printing apparatus 400 is a kind of image forming apparatus, and upon receiving processing information from the server apparatus 100, interprets PDL data and generates raster format image information. Then, the printing apparatus 400 performs printing based on the image information representing each page according to the formation conditions included in the processing information. In this embodiment, three types of “paper feeding”, “single / double-sided”, and “offset discharge” are handled as the types of forming conditions. The formation condition “paper feed” is a condition relating to paper selection, and designates a paper feed unit that performs paper feed. The formation condition “paper feeding” represents either a paper feeding unit for feeding colored paper or a paper feeding unit for feeding white plain paper. The formation condition “one side / both sides” represents either printing on one side (one side) of the paper or printing on both sides of the paper. “Offset discharge” designates whether or not so-called offset discharge is performed, and indicates whether offset discharge is performed or not. This offset discharge is a function that shifts the discharge position of the paper by a predetermined unit so that a certain sorting unit is visually easy to understand, for example, when the delivery destination of an item is a sorting unit in a form. Corresponding to

FIG. 4 is a diagram for explaining an overview of functions realized by the document management system 1.
FIG. 4A is a diagram for explaining the contents of the processing information interpreted by the printing apparatus 400. In FIG. 9A, processing information is interpreted by the printing apparatus 400 from the upper side to the lower side. The command “* DJDE *” defines a description of formation conditions. The printing apparatus 400 identifies the formation condition from the description defined by this command, and sets the formation condition of the own apparatus accordingly. Note that “END;” defines that the description of the formation condition is ended.

  As shown in FIG. 5A, the processing information interpreted by the printing apparatus 400 includes PDL data corresponding to each page of a document including a total of 8 pages from the first page to the eighth page, and the PDL data. The formation conditions specified for each page of the document to be drawn are described. Based on this processing information, the printing apparatus 400 interprets that the formation condition represented by “* DJDE * FEED = AUX, DUP = NO, OFFSET = YES, END;” is specified for the first page, for example. Note that “FEED = AUX” means feeding (colored paper) from the paper feeding means identified by “AUX”. “DUP = NO” means that duplex printing is not performed, that is, simplex printing is performed. “OFFSET = YES” means that offset discharge is performed. Further, the printing apparatus 400 interprets that the formation condition “* DJDE * FEED = MAIN, DUP = YES, END;” is designated from the second page to the fifth page. “FEED = MAIN” means feeding (plain paper) from the paper feeding means identified by “MAIN”. “DUP = YES” means that duplex printing is performed. Here, there is no description about offset discharge, but in this case, it is specified not to perform offset discharge. In addition, the printing apparatus 400 specifies the formation condition “* DJDE * FEED = AUX, DUP = NO, OFFSET = YES, END;” on the sixth page, and “* DJDE” on the seventh to eighth pages. * FEED = MAIN, DUP = YES, END; ”is interpreted as being specified.

  Based on the above interpretation, the printing apparatus 400 performs printing according to the formation conditions specified for each page based on the acquired processing information, as shown in FIG. On the other hand, as shown in FIG. 4C, the server device 100 generates a PDF file based on the acquired processing information.

[Operation]
Next, the operation of the document management system 1 will be described.
[Operation of Server Device 100]
FIG. 5 is a flowchart illustrating a control procedure executed when the server apparatus 100 generates a PDF file based on the processing information. Hereinafter, an operation when the server apparatus 100 generates a PDF file based on the processing information interpreted with the content illustrated in FIG. 4A will be described.
When the control unit 110 of the server device 100 determines that control for generating a PDF file is started by operating the operation unit 130 by an operator, the processing unit 110 acquires processing information to be processed (step SA1). . For example, the control unit 110 stores processing information to be transmitted for printing on the printing apparatus 400 in the storage unit 140, and acquires this at the timing of generating a PDF file. Next, the control unit 110 reads the processing information and analyzes the content (step SA2). Then, control unit 110 determines whether or not the reading of the processing information has been completed (step SA3). Here, the control unit 110 determines that the reading has not been completed yet (step SA3; NO), and proceeds to the process of step SA4. Next, the control unit 110 determines whether or not the content read and analyzed in step SA2 is a forming condition (step SA4).

  Here, if the control unit 110 determines that the content read and analyzed in step SA2 is the formation condition (step SA4; YES), the control unit 110 stores the formation condition information indicating the acquired formation condition in the storage unit 140. (Step SA5). And the control part 110 returns to the process of step SA2. FIG. 6 is a diagram illustrating a data structure of formation condition information stored in the storage unit 140 by the process of step SA5. As shown in the drawing, “TotalPages: 8”, which is defined by PDL data and represents the total number of pages of the PDF file, is described at the beginning. Subsequently, a value indicating the start page of each forming condition and a forming condition designated for each page are described.

On the other hand, when the control unit 110 reads PDL data in step SA2 and determines in step SA4 that the read content is not a formation condition (step SA4; NO), the process proceeds to step SA6. In this case, since the control unit 110 has read the PDL data from the processing information, the control unit 110 converts the read PDL data into a description format according to the PDF format, and stores the document information obtained by the conversion in the storage unit 140. Store (step SA6). And the control part 110 returns to the process of step SA2.
The control unit 110 repeatedly executes the above processing steps until all the PDL data and formation conditions included in the processing information are read.

  When determining that the reading of the processing information has been completed from the reading result of step SA2 (step SA3; YES), control unit 110 proceeds to the processing of step SA7. Then, the control unit 110 generates a PDF file based on the formation condition information having the contents shown in FIG. 6 stored in step SA5 and the document information of each page generated in step SA6 (step SA7). ). In step SA7, the control unit 110 describes the formation condition information using the “document information dictionary” described in the PDF file. This document information dictionary is a PDF file in which document attributes such as document title, creator, subject, keyword, document creation date and time are described as metadata.

FIG. 7 is a diagram for explaining the data structure of a PDF file.
As shown in FIG. 5A, the PDF file includes a display information area T1 and a non-display information area T2. Information related to document display is described in the display information area T1. In the display information area T1, for example, information defining specific contents is described. Information other than information related to document display is described in the non-display information area T2. An area in which the “document information dictionary” is described is included in the non-display information area T2, and besides this, a page tree (page structure information) that defines the page structure of the PDF file, information that defines a layout, and the like Is described. The content related to the information described in the non-display information area T2 is not displayed as an image when the document represented by the PDF file is displayed on the display unit 150, 250 or the like. That is, the description in this area does not affect the display content of the document on each page.

FIG. 7B is a diagram illustrating an example of the data structure of the “document information dictionary” described in the non-display information area T2.
In FIG. 7B, the description “330 0 obj” at the beginning defines that information related to the object with the object number “330” for identifying each object is described. Subsequent description “/ keywords (...)” Defines that a keyword related to the PDF file is described in the area “... Following the description of “\ n”, the formation condition information having the contents shown in FIG. 6 is described. This description does not adversely affect the interpretation of document attributes described in the document information dictionary. In the formation control information, for the page that is not designated as the start page of the formation condition, the same formation condition as that of the immediately preceding page is adopted. In FIG. 7B, “trailer” defines the start position of the file trailer. The description “info 330 0 R” defines that the object with the object number “330” indicates the document information dictionary in which the attribute of the document is described. That is, this document information dictionary is a dictionary that is referred to by the Info entry of the file trailer.

The control unit 110 outputs the PDF file generated by the above control by transmitting it to the PC 200 by the communication unit 120 when instructed by the operator or periodically. When the communication unit 220 receives the PDF file by the communication unit 220, the control unit 210 of the PC 200 stores the PDF file in the storage unit 240. At this time, the PC 200 accumulates the PDF file in the storage unit 240 by dividing the storage folder for each category.
The above is the description regarding the control performed when the server apparatus 100 generates a PDF file.

[Operation of PC200]
Next, control executed when the PC 200 forms an image on the image forming apparatus 300 based on the PDF file stored in the storage unit 240 will be described. FIG. 8 is a flowchart showing a control procedure executed by the PC 200 at this time.
When the operation unit 230 is operated by the user and the user instructs the control unit 210 of the PC 200 to form an image based on the PDF file generated from the processing information illustrated in FIG. The PDF file is read and acquired (step SB1). Then, the control unit 210 analyzes the PDF file, reads the formation condition information described in the document information dictionary, and specifies the formation condition specified for each page of the PDF file (step SB2). Then, the control unit 210 converts the PDF file acquired in step SB1 into data described in a page description language that can be interpreted by the image forming apparatus 300, and this data and an instruction related to a page on which an image is to be formed. Then, an image forming instruction including an instruction regarding the forming conditions to be followed by the image forming apparatus 300 is generated and transmitted to the image forming apparatus 300 (step SB3). Through the above processing steps, the PC 200 causes the image forming apparatus 300 to form an image related to each page represented by the PDF file in accordance with the forming conditions specified based on the PDF file.

The process of step SB3 will be described more specifically. FIG. 9 is a diagram for explaining the structure of an image formation instruction transmitted by the PC 200 when an image related to all pages of the PDF file is to be formed in step SB3.
First, the control unit 210 generates and transmits an image formation instruction A in order to form an image related to the first page under the formation conditions specified for the first page. This image formation instruction A represents data in which all eight pages of the PDF file are described in a page description language, an instruction “RANGE = 1” with the first page as an object of image formation, and formation conditions. The instruction “FEED = AUX DUP = NO OFFSET = YES” is included.

  Next, the control unit 210 generates and transmits an image formation instruction B in order to form images related to the second page to the fifth page. In this image formation instruction B, data relating to all eight pages of the PDF file, an instruction “RANGE = 2-5” for image formation from the second page to the fifth page, and these pages are designated. The instruction “FEED = MAIN DUP = YES OFFSET = YES” indicating the formation conditions is included. Thereafter, the control unit 210 generates an image formation instruction C including data relating to all eight pages of the PDF file, an instruction to set the sixth page as an object of image formation, and an instruction for the formation condition specified for the sixth page. Finally, an image forming instruction D including data relating to all eight pages of the PDF file, instructions for forming the seventh and eighth pages as image formation targets, and instructions for forming conditions for these pages is generated. Then send.

  As described above, the server apparatus 100 generates a PDF file including formation condition information indicating the formation conditions of each page. Since the PC 200 specifies the formation conditions of each page of the PDF file based on the formation condition information and generates and transmits an image formation instruction, even in a general-purpose image forming apparatus, the same as before conversion of this data format An image can be formed under the forming conditions. In addition, since the formation condition information is described in the document information dictionary included in the PDF file, the original contents of the document can be changed when the document is displayed on the display device or the image related to the document is formed without deleting the description. In these cases, the contents relating to the formation condition information are not visually recognized by the user. Further, since the formation condition information for each page is collectively described in an area where the document information dictionary is described, the PC 200 can specify the formation condition for each page by reading and analyzing the document information dictionary. Therefore, even if the number of pages of the PDF file becomes enormous and the amount of calculation related to the analysis of the forming condition information increases accordingly, the amount of calculation related to the analysis increases compared to the case where the description area is divided into a plurality of parts. It is suppressed.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The configuration of the document management system according to the second embodiment and the hardware configuration of each device are the same as those of the first embodiment described above. Description is omitted. The difference from the first embodiment described above is that, in the first embodiment, the formation condition information is described using the “document information dictionary” included in the PDF file. The formation condition information is described using a “page tree” that defines the page structure of the document. The page tree is a page structure information that defines a page structure in the PDF file with a tree structure having a dictionary referred to by a page entry of the file trailer as a root. This page tree is also described in the non-display information area T2 shown in FIG. 7A, and does not affect the display of the document on the display device.

FIG. 10 is a diagram illustrating an example of a data structure of a page tree in which formation condition information is described. FIG. 11 schematically shows the relationship between objects (pages) defined in the page tree shown in FIG. 10 and 11 show a page tree described based on the processing information shown in FIG.
As shown in FIG. 10, “2 0 obj << / Type / Pages Kids [3 0 R 4 0 R 5 0 R... 10 0 R] / Count 8 /. > ”. This description defines that the object with the object number “2” is the parent and each object with the object numbers “3” to “8” is its direct child. The page order of the PDF file is defined by each object from the object numbers “3” to “8”. Specifically, as shown in FIG. 11, the object with the object number “3” corresponds to the first page, the object with the object number “4” corresponds to the second page,..., The object number “10” Correspond to the eighth page. In this way, in PDF format data, information related to the page structure is described by dividing an object (area) for each page.

  In the description area el1 of FIG. 10, information related to the first page of the PDF file corresponding to the object with the object number “3” is described. In this description area el1, “/ PieceInfo <<... Private << / Duplex (NO) / FEED (AUX) / OFFSET (YES) >> >>” is described. The description “PieceInfo” defines that a document information dictionary (hereinafter referred to as “page piece dictionary”) that defines a page tree is described. In the area defined by "PieceInfo", "Private << ... >>" is described, and in the part of "...", formation condition information indicating the formation condition specified on the first page is displayed. It has been described. By this description, the formation condition information does not adversely affect the interpretation of the page tree. The meaning of the formation condition information is the same as the formation condition of the first page shown in FIG. 6, and the description format is only slightly different.

  The description area el2 in FIG. 10 corresponds to the object with the object number “4” and describes information related to the second page of the PDF file. In this area, “/ PieceInfo << ・ ・ ・ Private << / Duplex (YES) / FEED (MAIN) >> >>” is described, and the formation condition information corresponding to the second page is described. . The description area el3 in FIG. 10 corresponds to the object with the object number “10” and describes information related to the eighth page of the PDF file. In this area, “/ PieceInfo << ・ ・ ・ Private << / Duplex (NO) / FEED (AUX) / OFFSET (YES) >>” is described, and the formation condition information corresponding to the eighth page is described. Yes. For other objects, the formation condition information is described in the page piece dictionary corresponding to each page according to the same rule as described above.

Next, the control executed when the server apparatus 100 generates a PDF file based on the processing information will be described. FIG. 12 is a flowchart illustrating a control procedure executed by the server apparatus 100 at this time. Note that the same processing steps as those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof is omitted.
The control unit 110 of the server device 100 sequentially executes the processes from step SA1 to SA3 in the same procedure as in the first embodiment, and determines whether or not the formation conditions included in the process information have been read (step SA4). When the control unit 110 determines that the formation condition has been read (step SA4; YES), the control unit 110 stores the formation condition information indicating the formation condition in the storage unit 140 (step SA5).

On the other hand, when the control unit 110 determines that the read content is not a forming condition (step SA4; NO), it means that the PDL data has been read, so the read PDL data is converted into a PDF format description and converted. The contents are stored in the storage unit 140 (step SA6). Then, control unit 110 determines whether or not conversion of document information for one page has been completed (step SA10). Here, if the control unit 110 determines “NO”, until the conversion of the document information for one page is completed, step SA2 → SA3 “NO” → SA4 “NO” → SA6 → SA10 “NO” →. Repeat the processing steps. Then, when the conversion of the document information for one page is completed (step SA10; YES), the control unit 110 describes the formation condition information for the page in the page piece dictionary, and the PDF together with the already completed page. A file is generated (step SA11).
The control unit 110 repeats the above processing steps for all pages, and if “YES” is determined in step SA3, the processing related to the generation of the PDF file ends. The contents of the control for transmitting the PDF file to the PC 200 by the server apparatus 100 and the control for causing the image forming apparatus 300 to form an image by the PC 200 are the same as those in the first embodiment described above, and the description thereof will be omitted.

  As described above, according to the second embodiment, the server apparatus 100 describes the formation condition information in the page piece dictionary in the page tree that defines the page structure of the PDF file. With this configuration, since the formation condition information indicating the formation condition of each page is described in the page piece dictionary of the corresponding page, the number of pages such as deleting some pages in the PDF file is changed. Even if the processing is performed, the PC 200 can correctly specify the forming conditions for each page and cause the image forming apparatus 300 to form an image.

The element having the element name “feed” defines the formation condition “paper feeding”. The element having the element name “dup” defines the formation condition “double-sided / single-sided”. The element having the element name “offset” defines the formation condition “offset discharge”. In the description area el11, “<startpage> 1 </ startpage>” is described, and formation condition information indicating a formation condition having the first page as the start page is described. In the description area el12, “<startpage> 2 </ startpage>” is described, and formation condition information indicating a formation condition having the second page as the start page is described. In the description area el13, “<startpage> 7 </ startpage>” is described, and formation condition information indicating a formation condition having the seventh page as a start page is described. Even in the configuration of this modified example, the same formation condition as that of the immediately preceding page is adopted for the page that is not designated as the start page of the formation condition. As described above, in the PDF file, the data description format may vary depending on the version of the application software used to generate the PDF file, but the server apparatus 100 is formed in the area where the document attribute is described. If it is the structure which describes condition information, there exists an effect equivalent to 1st Embodiment mentioned above.

[Modification 3]
In the first embodiment described above, after the PDF file is generated, the PDF file may be edited using the PC 200 or the like to change the number of pages. Also in this case, the PC 200 may adopt the following configuration so that the formation conditions for each page can be accurately specified.
When the PC 200 is instructed to form an image based on a certain PDF file, the PC 200 reads the formation condition information from the PDF file. Then, the PC 200 specifies the total number of pages when the PDF file is generated from the description “TotalPages: 8” in the document information dictionary shown in FIG. Subsequently, the PC 200 specifies the total number of pages of the PDF file at the current time, and determines whether this matches the total number of pages specified by the document information dictionary. If the PC 200 determines that they match, the PC 200 causes the image forming apparatus 300 to form an image according to the procedure described in the first embodiment. On the other hand, if the two are different, the PC 200 may not be able to designate an accurate formation condition for each page of the PDF file, so that an image is formed by causing the user to designate the formation condition again. In this case, the PC 200 may display a message such as “Could not specify printing conditions” on the display unit 250 to notify the user of that, or even if the processing for forming the image itself is stopped. Good. This configuration may be the configuration according to the above-described modification 2. In this case, the PC 200 specifies the total number of pages from the description of “<TotalPages> 8 </ TotalPages>” shown in FIG. Good.

[Modification 4]
In the first and second embodiments described above, the types of formation conditions are three types of “paper feeding”, “single / double-sided”, and “offset discharge”. However, the types and numbers are limited to those of the embodiment. Not. For example, “monochrome / color” that switches between black-and-white image formation and multi-color image formation may be adopted, the selection of the discharge means for discharging the paper, the binding direction, the presence or absence of staples, the punch hole Formation conditions that specify the presence or absence of formation may be employed.

[Modification 5]
In the embodiment described above, the server apparatus 100 uses the first and second data described above in which the contents (values) to be entered in each column of the standard format are described in accordance with, for example, the CSV (Comma Separated Value) format. It may be used instead of the image forming data of the second embodiment. In this case, in the document management system 1, PDL data is generated based on these data and fixed form data defining a fixed form, and the first and second embodiments are based on the PDL data. Perform the control described. The drawing information described in the page description language is not limited to various document files and image files, and may be data that can be interpreted by the server apparatus 100 such as an intermediate code. In short, the server device 100 may be configured to generate a PDF file based on drawing information in which a process of drawing a document of a plurality of pages is described and a formation condition is specified for each page of the document. Note that information indicating the formation condition is included in the PDL data, and the server apparatus 100 may acquire the formation condition from the PDL data.
The data format of the document information generated by the server device 100 is not limited to the PDF format, but may be a TIFF (Tagged Image File Format) format or a data format that is not intended for display on the display device. Also good. Further, if the server apparatus 100 generates document information in a data format having an area describing document attributes and an area describing page structure information indicating the page structure, the above-described first and second embodiments are used. Equivalent effect.

  In the second embodiment described above, the server apparatus 100 describes the formation condition information in the page tree. With this configuration, even if the processing for changing the number of pages is performed on the PDF file, the PC 200 can correctly specify the formation conditions of each page. That is, not only the page structure information such as the page tree, but the server apparatus 100 describes the information related to each page in the document file by dividing the area for each page, and describes the formation condition information in the corresponding page area. If it is a structure, there exists the structure equivalent to the above-mentioned 2nd Embodiment.

[Modification 6]
In the first and second embodiments described above, the “annotation function” for inserting an annotation into a document, the “text box” for inserting a character string, and the “comment” for inserting a comment, which are provided in the application software that handles PDF format data The formation condition information may be described using “function” or the like. When a document based on the PDF file is displayed on the display device, it is preferable that the content related to the formation condition information is not displayed there. However, the formation condition information is described in the display information area T1 shown in FIG. Even if the configuration is adopted, the same effects as those of the first and second embodiments are obtained except that the information related to the formation condition information is displayed. In this case, when converting the PDF file into data for image formation described in a page description language, the PC 200 may delete the description corresponding to the formation condition information after designating the formation conditions.
