  FIG. 4 is a schematic diagram showing a paper document output from the image processing apparatus 20.

  As shown in FIG. 4, a code pattern is printed on a sheet of paper document output by being overprinted from the image processing apparatus 20.

  Since the code pattern is composed of dots and is arranged finely so that three dots are arranged in a 0.5076 mm square, the electronic document is printed on paper even if it is overlaid with the image data of the electronic document. Visible.

  Next, a code pattern superimposed and printed on a paper document output from the image processing apparatus 20 will be described with reference to FIG.

  FIG. 5 is a schematic diagram showing a code pattern. FIG. 5A is a schematic diagram showing a unit code of a minimum constituent unit of a code pattern composed of dots, and FIG. 3B is a schematic diagram showing a code block composed of 25 unit codes. FIG. 3C is a schematic diagram showing a code pattern on a paper document.

  As shown in FIG. 5 (a), a square having a side of 0.5076 mm is divided into a total of nine in three vertical and three horizontal directions, and three small squares are selected from the nine small squares formed by the division. The dots are placed in the selected small square. Since 3 out of 9 locations are selected, there are 84 combinations of unit codes (9C3). A square in which three dots are arranged and one side is 0.5076 mm is a unit code that is the minimum constituent unit of the code pattern.

  Also, as shown in FIG. 5B, 25 unit codes are arranged in a square shape with 5 vertical and 5 horizontal, forming one code block. Therefore, the length of one side of one code block is 2.538 mm.

  In this one code block, as shown in FIG. 5B, one synchronization code, which is a unit code in which synchronization information is recorded, and a unit code in which the X coordinate on the printed paper is recorded. , Four unit codes for recording the Y coordinate on the paper to be printed, and 16 unit codes for recording the identification information of the paper document to be output.

  Then, as shown in FIG. 5C, the code pattern formed by such code blocks is superimposed and printed with the image data of the electronic document on the paper to be printed.

  Next, the unit code will be described with reference to FIG.

  FIG. 6 is a schematic diagram showing unit codes, FIG. 6 (a) is a schematic diagram showing one unit code, and FIG. 6 (b) is a schematic diagram showing various unit codes.

  As shown in FIG. 6A, a unit code is selected by selecting a square having a side of 0.5076 mm divided into three vertical parts and three horizontal parts, and a total of nine parts. Dots are placed at the three locations.

  The types of unit codes formed by selecting three out of nine are combinations in which three out of nine different types are selected, and therefore, (9C3) and 84 types. (See FIG. 6 (b)).

  In this way, 84 kinds of information are recorded in one unit code, but only 64 kinds of information are recorded in this embodiment. That is, 6-bit information can be recorded for each unit code. However, of course, it may be configured to record 84 kinds of information in one unit code.

  Next, a code block composed of 25 unit codes will be described with reference to FIG.

  FIG. 7 is a schematic diagram showing a code block.

  As shown in FIG. 7, in the code block, one unit code is arranged as a synchronization code at the upper left (reference number 701), and the X coordinates in the paper to be printed are displayed on the four rightmost columns. Four unit codes are arranged as reference X coordinate codes (reference number 702).

  Then, four unit codes are arranged as Y coordinate codes indicating the Y coordinates in the printed paper in the lower four of the leftmost column of the code block (reference number 703).

  Further, an identification code, which is a unit code in which identification information is recorded, is arranged at a place where 16 unit codes of 4 × 4 at the lower right of the code block are arranged (reference number 704).

  This identification code is a code in which identification information uniquely given to a paper document output from the image processing apparatus 20 is recorded. The identification information is recorded after being subjected to RS (Reed-Solomon Coding) coding with an error correction function, so if it has the correction capability of three unit codes (6 bits x 3 = 18 bits), it will be 16 60-bit identification information is recorded in the unit code (6 bits × 16 = 96 bits).

  Thus, the synchronization code, the X coordinate code, the Y coordinate code, and the identification code are arranged in the code block.

  Next, information recorded in the X coordinate code and the Y coordinate code will be described with reference to FIG.

  FIG. 8 is a schematic diagram showing information recorded in the X coordinate code and the Y coordinate code.

  As shown in FIG. 8, an X coordinate and a Y coordinate are set as coordinate information on the paper to be printed, and a position on the paper is specified by the two coordinates. Further, regarding a single paper document that has been cut and pasted and combined, which part of the original paper document is used is also expressed by the coordinate information of the X coordinate and the Y coordinate.

  As the coordinates, a numeric string represented by an M series is used. The P-th order M-sequence has a property that when P consecutive bit strings are extracted from the numeric string represented by the M-sequence, the P-sequence does not appear in other parts of the numeric string. The position in the coordinate axis is specified using the property of the M series.

  For example, if a 12th order M sequence is used for the M sequence, the sequence length of the M sequence is 4095 (= 2 to the 12th power-1).

  As the coordinate value, in both the X and Y directions, the M-sequence numerical value is divided into blocks each having 4 bits, and each divided block is sequentially arranged at a position where an X coordinate code sandwiched between synchronization codes is indicated. To do. Similarly for the Y coordinate, coordinate information indicating the position on the paper to be printed is recorded in the unit code in which the X coordinate code and the Y coordinate code are recorded. However, the X coordinate code and the Y coordinate code may be configured to record 6-bit information instead of recording 4-bit information in one unit code.

  Thus, since 4-bit coordinate information is recorded in one unit code, 16-bit information is recorded for each coordinate in one code block. Therefore, an M-sequence having a sequence length of 4095 is divided and recorded in 255 (= 4095 ÷ 16) code blocks, and the size of one code block is 2.538 mm, so the length of 255 consecutive code blocks is obtained. Becomes 647.19 mm, and the length of 647.19 mm can be encoded. That is, encoding can be performed up to A2 size (420 mm × 594 mm) paper.

  Although this is an example in which the position is encoded with one M sequence, the number of positions that can be encoded can be further increased by connecting a plurality of M sequences. For example, even when an 11th order M-sequence is used, A0 size paper can be encoded by connecting four of them.

  Next, FIG. 9 shows how the information detection unit 204 detects information from the code pattern superimposed and printed on the paper document when the paper document synthesized by cutting and pasting by the user is copied by the image processing apparatus 20. The description will be given with reference.

  FIG. 9 is a schematic diagram showing how information is detected from a code pattern superimposed and printed on a paper document by the information detection unit 204 of the image processing apparatus 20.

  As shown in FIG. 9, in the document processing system 60, the paper document output from the image processing apparatus 20 is cut and pasted to synthesize one paper document. In the example shown in FIG. 9, the plurality of paper documents to be cut and pasted are paper documents whose identification information (pID) is 1 (pID = 1) and 2 (pID = 2).

  As a result of cutting and pasting the identification information from the paper documents 1 and 2, one paper document is synthesized. Cut and paste may be a part of a paper document with identification information 1 and a part of a paper document with identification information 2 cut out with a scissors or the like and pasted on a single sheet of paper. A part of a paper document with 1 and a part of a paper document with identification information 2 may be bonded with a tape or the like to be combined as a single paper document, or a part of one paper document may be cut out. Alternatively, it may be combined as a single paper document by being pasted on the other paper document.

  Since the identification information is recorded as a code pattern as 1 in the paper document with the identification information 1, it is a part of one synthesized paper document and the original paper document has the identification information 1 In addition, the identification information is recorded as 1 as a code pattern (reference number 901).

  Further, since the identification information 2 is recorded as the code pattern in the paper document with the identification information 2, the original paper document has the identification information 2 which is a part of one synthesized paper document. Also in a certain part, identification information 2 is recorded as a code pattern (reference number 902).

  When the image processing apparatus 20 issues a copy instruction to the combined paper document in this way, the code pattern reading unit 203 of the image processing apparatus 20 detects the code pattern of the combined single paper document. (Reference number 903).

  And the information detection part 204 reads the information recorded on the detected code pattern.

  Information read by the information detection unit 204 is identification information and coordinate information of a paper document recorded in a code pattern of the paper document. Then, based on the identification information and the coordinate information read by the information detection unit 204, the document information generation unit 206 includes the identification information 1 in a specific part of the synthesized paper document (reference number 904 (A)). A specific part of the paper document (reference number 905 (A)) is arranged, and the specific part of the synthesized paper document (reference number 906 (B)) contains the paper document of the identification information 2 It is clarified that a specific part (reference numeral 907 (A)) is arranged. As described above, when the information detection unit 204 detects the identification information and the coordinate information of the paper document from the code pattern, the document information generation unit 206 synthesizes the synthesized paper document with the document at which position of which paper document. Information on whether or not the document is displayed is acquired as document information.

  Next, how to indicate a paper document area and document information will be described with reference to FIG.

  FIG. 10A shows a paper document area where coordinate information is used, FIG. 10B is a schematic diagram showing a synthesized paper document, and FIG. 10C shows document information. FIG.

  As shown in FIG. 10A, an area surrounded by a quadrilateral of a paper document is expressed by the upper left coordinates and the lower right coordinates of the quadrilateral. That is, when the upper left coordinate is (X, Y) and the lower right coordinate is (X ′, Y ′), the rectangular area is expressed as (X, Y, X ′, Y ′). The In this way, the area on the paper document is expressed using the coordinate information.

  Then, as shown in FIG. 10B, there is a paper document obtained by cutting and pasting a paper document, and the cut and pasted paper document that is the source of synthesis is a paper document with identification information 1, 2, and 3. is there. As shown in FIG. 10C, the document information indicating the information of the paper document that is the synthesis source of the synthesized paper document has the identification information 1 in the area (0,0,300,250) of the synthesized paper document. An area (0,0,300,250) of a paper document (pID = 1) is arranged, and an area of a paper document (pID = 2) having identification information 2 is included in the synthesized paper document area (0,250,150,500). The document (0,0,150,250) is arranged, and the area (150,0,300,250) of the paper document (pID = 3) whose identification information is 3 is arranged in the area (150,250,300,500) of the synthesized paper document. Has been.

  The layout area indicating the position where the paper document to be synthesized is arranged on the paper, the identification information of the paper document to be synthesized, and the portion of the area of the paper document to be synthesized are synthesized. The acquisition area indicating whether or not the document has been used is used as document information.

  Next, a process of copying a synthesized paper document in the document processing system 60 will be described with reference to FIG.

  FIG. 11 is a schematic diagram showing a process for copying a synthesized paper document in the document processing system 60.

  As shown in FIG. 11, two paper documents having different identification information are output from the image processing apparatus 20. The identification information of one paper document is 1 (pID = 1), and the identification information of the other paper document is 2 (pID = 2) (reference number 1101).

  Then, the two paper documents are cut and pasted to synthesize one paper document. A part of the paper document with the identification information 1 is cut out (reference number 1102), the paper document with the identification information 2 is cut out (reference number 1103), and the paper document with the cut identification information of 1 and the paper of 2 are cut out. The document is pasted with a tape or the like, and a single paper document is synthesized (reference number 1104).

  When one paper document synthesized in this manner is placed in the image reading unit 202 of the image processing apparatus 20 and a copy instruction is given, the code pattern of the placed paper document is detected. Then, the information detection unit 204 of the image processing apparatus 20 detects the identification information and the coordinate information recorded in the detected code pattern, and the document information generation unit 206 of the image processing apparatus 20 is arranged in the image reading unit 202. Get the document information of the paper document.

  When the document information is acquired, the image processing apparatus 20 transmits the acquired document information to the electronic document server 30 (reference number 1105).

  The electronic document server 30 performs a copying process in accordance with the document management policy stored in the electronic document server 30 based on the contents described in the acquired document information (paper document identification information and its acquisition area). The processing permission determining unit 304 determines whether or not the permission is permitted.

  In the document management policy stored in the electronic document server 30, permitted processing is set for each paper document. The permitted processing is, for example, copying or cutting.

  It is also possible to set so that a specific area of a paper document is designated and the area is prohibited from being cut off.

  It is also possible to set a specific area of the paper document so that the area is prohibited from being combined with another document.

  It is determined whether or not the copying process is permitted in accordance with the document management policy. If the result of the determination is that the copying process is permitted, the printing source of the paper document described in the document information is determined. The resulting electronic document is sent to the identification information management server 40. The paper document from which the paper document placed in the image reading unit 202 is synthesized is a paper document with identification information 1 and 2, and the electronic document that is the printing source of the paper document with identification information 1 and 2 is used. An inquiry about what the document is is sent from the electronic document server 30 to the identification information management server 40.

  Upon receiving the inquiry, the identification information management server 40 searches for the electronic document that is the printing source of the paper documents whose identification information is 1 and 2 by the tracking information stored in the identification information management server 40.

  When the printing source electronic document is searched in the identification information management server 40, the number of the searched electronic document is sent to the electronic document server 30.

  The electronic document server 30 that has received the electronic document number searches the electronic document storage unit 305 for the electronic document with the received number, and manages the retrieved electronic document and the document information sent from the image processing apparatus 20. It transmits to the server 40 (reference number 1106). In this example, the print source electronic documents of the paper documents having identification information 1 and 2 are described assuming that the electronic document identification information is 1 (eID = 1) and the electronic document identification information is 2 (eID = 2). Do.

  In the identification information management server 40 that has received the electronic document with the identification information 1, the electronic document with the identification information 2, and the document information, the received electronic document is processed based on information such as the acquisition area described in the document information, The same image data as the paper document arranged in the image reading unit 202 of the image processing apparatus 20 is synthesized. The image data of the acquisition area described in the document information of the paper document whose identification information is 1 and the image data of the acquisition area described in the document information of the paper document whose identification information is 2 are combined into one Image data is created.

  The image data combined in this way is sent from the identification information management server 40 to the image processing apparatus 20, and is output by being superimposed on a code pattern in which identification information is newly recorded by the image processing apparatus 20 (reference number 1107). ). For example, if the new identification information is 3, the identification information of the paper document output from the image processing apparatus 20 is 3 (pID = 3).

  Next, in the document processing system 60, a sequence shown in FIG. 12 will be described with respect to the processing when the image processing apparatus 20 copies a single paper document obtained by cutting and combining the paper document output from the image processing apparatus 20. Further description will be given with reference to the drawings.

  FIG. 12 is a sequence diagram illustrating a process in which the synthesized paper document is copied by the image processing apparatus 20 in the document processing system 60.

  When a sheet of paper that is superimposed and output from the image processing apparatus 20 is cut and pasted and a single paper document is synthesized (reference number 1104 in FIG. 11), the paper document is sent to the image reading unit 202 of the image processing apparatus 20. Arranged and instructed to copy. When a copy instruction is issued, the paper document on which the image reading unit 202 is arranged is read (reference number 1201), and a code pattern is detected by the code pattern detection unit 203 from the read image data (reference number 1202). . For the code pattern detected by the code pattern detection unit 203, the information detection unit 204 detects the identification information and coordinate information of the paper document (reference number 1203). Then, by detecting the coordinate information of the paper document, document information indicating which acquisition area of the paper document of which identification information is arranged and in which arrangement area of the paper document to be synthesized is generated as document information Obtained by the unit 206 (reference number 1204).

  The acquired document information is transmitted from the image processing apparatus 20 to the electronic document server 30.

  In the electronic document server 30, a paper document described in the document information acquired from the image processing apparatus 20 in accordance with the document management policy stored in the policy storage unit 306 in the electronic document server 30 by the processing permission determination unit 304. It is determined whether or not copying processing is permitted for the acquired area according to the document management policy.

  If it is determined that the copying process is not permitted (NO at reference numeral 1205), the electronic document server 30 notifies the image processing apparatus 20 that the copying process is not permitted and the output is prohibited. The image processing apparatus that has received the message indicating that the output is prohibited stops the copying process (reference number 1206).

  If the result of determination by the processing permission determination unit 304 of the electronic document server 30 is that copying is permitted (YES at reference numeral 1205), the document information acquired by the electronic document server 30 from the image processing apparatus 20 is added. An inquiry about the identification information of the electronic document that is the printing source of the paper document to be described is made from the electronic document server 30 to the identification information management server 40. The inquiry is made by transmitting, to the identification information management server 40, the identification information of the paper document that constitutes the paper document described in the document information received from the image processing apparatus 20.

  The identification information management server 40 that has been queried searches the electronic document from which the paper document of the identification information sent from the electronic document server 30 was printed from the tracking information stored in the storage unit 402 (reference number 1207). ), The identification information of the electronic document to be printed as a search result is transmitted to the electronic document server 30.

  When the identification information of the electronic document to be printed is sent to the electronic document server 30, the electronic document server searches the electronic document storage unit 305 for the electronic document with the sent identification information, and the electronic document that is the search result, and the image The document information received from the processing device 20 is transmitted to the identification information management server 40.

  In the identification information management server 40 that has received the electronic document and the document information, the received electronic document is processed based on the document information, and image data of a paper document arranged in the image reading unit 202 of the image processing apparatus 20 is generated. (Reference number 1208).

  When image data is generated by the identification information management server 40, the generated image data is transmitted to the image processing device 20.

  In the image processing apparatus 20, new identification information recorded in the output paper document is generated by the identification information generation unit 205 (reference number 1209).

  When new identification information is generated, new identification information and document information acquired by the document information generation unit 206 (document information acquired by reference number 1204) are transferred from the image processing apparatus 20 to the identification information management server 40. Is transmitted (reference number 1210).

  In the identification information management server 40 to which the new identification information and the document information are transmitted, tracking information about the paper document output from the image processing apparatus 20 is generated. The tracking information is tracking information about the paper document with new identification information transmitted from the image processing apparatus 20 (transmitted with reference number 1210), and the image data of the paper document newly output from the image processing apparatus 20 is This is information that makes it clear which part of which paper document is arranged at which position (the tracking information will be described in detail later with reference to FIG. 15).

  In the image processing apparatus 20, a code pattern in which new identification information is recorded is generated by the code pattern generation unit 208, and the code pattern and image data received from the identification information management server 40 are superimposed and printed by the print execution unit 209. A paper document is output (reference number 1211).

  Next, referring to FIG. 13, the document processing system 60 determines whether or not the electronic document server 30 permits the copying process when the synthesized paper document is copied by the image processing apparatus 20. And explain.

  FIG. 13 is a flowchart showing a process for determining whether or not the copy process is permitted in the electronic document server 30.

  This process is performed by transmitting document information from the image processing apparatus 20 when the image processing apparatus 20 copies a document.

  When the document information transmitted from the image processing apparatus 20 is received, in the electronic document server 30, the image determination unit 304 determines whether or not the copying process is permitted based on the received document information information.

  First, the image determination unit 304 determines whether or not the paper document described in the document information is a separation prohibition document (step 1301). The determination as to whether or not the document is a separation-prohibited document is made based on whether or not the paper document having the identification information described in the document information is a document that is prohibited from being separated along the document management policy stored in the policy storage unit 306. .

  In the document management policy stored in the policy storage unit 306, as shown in FIG. 14, the permitted processing contents, various prohibited areas, and the users who are permitted to process are described for each paper document. Accordingly, the document management policy of the paper document having the identification information described in the document information is retrieved from the policy storage unit 306, and it is determined whether or not the retrieved document management policy prohibits the separation of the paper document. The

  If the paper document described in the document information is not a document that cannot be separated along the document management policy (NO in step 1301), the acquisition area of the paper document described in the document information conforms to the document management policy. Then, it is determined whether or not the area does not correspond to the separation prohibited area (step 1302).

  As shown by reference numeral 1401 in FIG. 14, the separation prohibited area is set in various prohibited area fields of the document management policy, and the paper document described in the set separation prohibited area and document information. In the case where the area of the acquisition area overlaps, the paper document to be copied is assumed to include a separation prohibition area.

  If the paper document acquisition area described in the document information does not correspond to the separation prohibition area (NO in step 1302), the paper document acquisition area described in the document information is further set in the document management policy. Along with this, it is determined whether or not the region does not fall within the combination prohibited area (step 1303).

  The area designated as the combination prohibition area is prohibited from being combined with another paper document and combined into a single paper document.

  Similarly to the separation prohibition area, the combination prohibition area is set in various prohibition area columns of the document management policy as indicated by reference numeral 1401 in FIG. When the area of the acquisition area of the paper document described in the information overlaps, it is assumed that the paper document to be copied includes a combination prohibited area.

  If it does not correspond to the combination prohibited area (NO in step 1303), it is further determined whether or not there is no image defect in the image data read by the document reading unit 202 of the image processing apparatus 20 (step 1304). ). Image defect of image data is determined by whether or not there is a defect in the arrangement area described in the document information (an area where a part of the paper document shown in the acquisition area is arranged on the read paper document) Is done. For example, when a sheet having an area of (0,0,300,500) is read, the arrangement area is lost without being the area of the sheet (0,0,300,500) when the arrangement area of the document information is totaled. The problem is whether or not a region exists. When the total of the arrangement area described in the document information is less than the area of the paper to be printed, it is determined that the image defect of the image data has occurred when the defect exceeds the range of the predetermined area. Is done.

  If no image loss has occurred in the image data (NO in step 1304), the determination result is that copying is permitted (step 1305).

  By the way, when the paper document or the paper document acquisition area described in the document information is a separation prohibited document (YES in step 1301), the copying process is restricted (step 1306). In addition, when it corresponds to the separation prohibited area at step 1302 (YES at step 1302), when it corresponds to the combination prohibited area at step 1303 (YES at step 1303), an image loss occurs at step 1304. If it is determined that the copy process has been made (YES in step 1304), the copying process is also restricted (step 1306).

  As described with reference to FIG. 12, the copy process is restricted not only by notifying the image processing apparatus 20 of the copy process prohibition notification but also by prohibiting the copy process at the management terminal 10 in the document processing system 60. A notification to that effect may be sent from the communication I / F unit 303. Alternatively, the restriction of the copy processing is notified from the electronic document server 30 to the image processing device 20 so that a warning is displayed on the image processing device 20 for the operator of the image processing device 20 performing the copy processing. The warning display may be combined with the copy processing prohibition notification and the notification to the management terminal 10 described above.

  Next, the tracking information stored in the storage unit 402 of the identification information management server 40 will be described with reference to FIG.

  FIG. 15 is a table showing the tracking information stored in the storage unit 402 of the identification information management server 40.

  As shown in FIG. 15, in the storage unit 402, which electronic document is output as the printing source of the paper document output from the image processing device 20, or which paper document is output from the image processing device 20 Information about whether or not a paper document has been output as a copy source (when copied from a single paper document cut and pasted and combined) is stored as tracking information.

  When the paper document output from the image processing apparatus 20 is output as an electronic document, the items stored as tracking information in the storage unit 402 include paper document identification information, output date and time, “print source” The identification information of the electronic document ”, the acquisition area, the arrangement area, and the rotation direction.

  In the paper document identification information item, identification information of a paper document output from the image processing apparatus 20 is stored.

  In the output date / time item, the date / time output from the image processing apparatus 20 is stored.

  In addition, in the item “identification information of the electronic document of the printing source”, identification information of the electronic document that is the printing source of the paper document output from the image processing apparatus 20 is stored.

  In the acquisition area item, the printed area of the printing source electronic document is stored as the acquisition area.

  In addition, in the item of the rotation direction, the image data of the electronic document indicated in the acquisition area is arranged by being rotated 0 degree, arranged 90 degrees, arranged 180 degrees, or arranged in the area indicated by the arrangement area. It is stored whether it has been arranged or rotated by 270 degrees.

  When the paper document output from the image processing apparatus 20 is copied and output from a single paper document that has been cut and pasted and combined, the items stored as tracking information in the storage unit 402 are the paper Document identification information, output date and time, “identification information of included paper document”, acquisition area, arrangement area, and rotation direction.

  In the paper document identification information item for copying, the paper document identification information output from the image processing apparatus 20 is stored.

  In addition, in the item of output date when copying, the date output from the image processing apparatus 20 is stored.

  In addition, in the item “identification information of included paper document”, identification information of a paper document to be combined with one copy source paper document is stored. For example, as shown in FIG. 15, when the identification information of the output paper document is 5, the copy source paper document is four paper documents (identification information 1, 2, 3, 4). Since the paper document is cut and pasted and synthesized, four pieces of paper document identification information are recorded in the item “identification information of included paper document”.

  In addition, in the item of the acquisition area in the case of copying, it is determined which part of the paper document recorded in the item “identification information of included paper document” was used to combine one paper document to be copied. The information shown is stored as an acquisition area.

  In addition, in the item of the arrangement area in the case of copying, the area in which the paper document indicated by the acquisition area is arranged as a copy is stored as the arrangement area.

  In addition, in the item of the rotation direction when copying, whether the image data of the paper document indicated by the acquisition area is rotated by 0 degrees or is rotated by 90 degrees, or is rotated by 180 degrees. It is stored whether it has been rotated and arranged by 270 degrees or 270 degrees.
