Description

  The present invention relates to a document management apparatus for storing identification information added to document image information, a document management system including the document management system, and a document management program.

In recent years, a method for storing document image information read by a scanner or the like in a storage unit of a personal computer has been widely used for document management in an office or the like. In addition to the functions of the conventional image forming apparatus, a similar document management method can be adopted even when using a multi-function machine that has a storage unit and can store the image information in the storage unit. It is.
In the above-described document management method, if the image information is stored in the storage unit, the image information can be read and printed as necessary. It has the convenience of being unnecessary.
However, if the amount of image information stored in the storage unit increases as the capacity of the storage unit increases, it becomes difficult to search for desired image information and read it out.

Therefore, it is very important for the purpose of document management that the image information is not stored in the storage unit but is stored in the storage unit with identification information for identifying and specifying the image information. Is important to.
Therefore, in Patent Document 1, when image information to be managed is printed as a document, a barcode is printed (applied) at a predetermined position of the document, and the user reads the barcode. A document editing apparatus that displays image information corresponding to the barcode is disclosed. In Patent Document 2, a document ID is issued when a document image is read, and a desired document can be retrieved and read by the document ID. Also, when the document is reprinted, the document ID is also printed on a sheet. A digital multifunction machine for printing is disclosed.
Japanese Patent Laid-Open No. 7-244657 JP 2003-67363 A

However, the techniques described in Patent Document 1 and Patent Document 2 described above have the following problems. That is, it is considered that the barcode, the document ID, etc. are not related to the contents of the document. Therefore, even if information such as the barcode and the document ID is given to the document, it is difficult for the user to recall the contents of the document from the information. There is an inconvenience that the correspondence between the document, the barcode, and the document ID must be referred to.
In order to eliminate such inconvenience, it is desirable to give information that allows the user to recall the contents, such as the creation date of the document and the name of the creator, as identification information for identifying the document.
Therefore, the present invention has been made in view of the above circumstances, and the purpose of the present invention is that there is no need to add special information such as the barcode and the document ID, and the user can edit the contents of the document. An object of the present invention is to provide a document management apparatus that can easily retrieve and read image information by providing identification information that can be recalled, and a document management system or document management program including the document management apparatus.

In order to achieve the above-described object, the present invention stores identification information associated with the image information in the document image information, and stores the position information of the specific description area on the document and the identification information. Storing a correspondence relationship with a related identification element, extracting the identification element from the position information of the description area read in the image information using the correspondence relationship, and adding the identification information from the identification element; The document management device is configured to be stored in the storage unit.
Thus, when the position information of the description area is read, the identification element is automatically extracted when reading the image information of the document, and the identification information is added to the image information and stored in the storage means. . For example, when the identification element is a date and the name of the creator of the document and the position information of the description area is read, a specific numerical value of the date (2/01, 5/18, etc.) is automatically obtained. , Identification information such as a specific name (Yamada, Kawada, etc.) of the creator of the document is generated, and the identification information is added to the image information (for example, the date is added to the file name, Stored in the directory corresponding to the extracted creator name among the created directories).
Here, as in the above-described example, the identification information (for example, 5/26, Saito, etc.) is specific information of the identification element (date, person in charge name, etc.). It is considered desirable for identification.
As a specific example of assigning identification information, it is conceivable to classify the image information using the identification information as classification information. In the above example, since the image information is classified based on the identification information related to the date and the creator name, the user can easily select desired image information based on the date or the creator name. Search and read can be performed.

Here, it is conceivable that the position information is specified (read) based on image information of a template document in which specific images are arranged at one or a plurality of locations. For example, when managing a document in a format specified by the layout of an entry frame, when using a blank document (only the entry frame is described) in that format as a template document, the entry frame is the specific image. Detected as Thereby, the position information of the description area can be specified (read) by various automatic and manual methods as described below.
As a method of automatically specifying the position information of the description area, a correspondence relationship between the specific image and the position information of the description area, for example, when the entry frame is detected as a specific image, It is conceivable to store the frame as the description area.
On the other hand, as a method for manually specifying the position information of the description area, the image information of the template document in which the entry frame is described is displayed on a display, and the user can display the position information while referring to the entry frame. It is possible to input.

Also, a correspondence relationship between the identification element and the identification information is stored, the extracted identification element and the identification information corresponding to the extracted identification element are collated, and the document is classified for each identification information for which the collation is established. It is possible. Thereby, the image information is classified after obtaining the identification information by a simple process of collating the extracted identification elements with the identification information based on the correspondence, and from other documents. Compared to the case of employing classification processing by comparison with the extracted identification element one by one, the processing load can be clearly reduced.
Further, when the extracted identification element has no correspondence with any of the stored identification information, a new correspondence between the identification element and the identification information is stored, and the new candidate is stored. It is conceivable to classify the image information.
In addition, when such an identification element is extracted, various processes such as batch classification into other documents or no storage of image information can be considered, and these processes are used depending on the situation. Just do it.
The present invention can be regarded as a document management device, a document management system having the document management device and an image reading device, or a document management program for causing a computer to execute identification information addition processing of the image information. It may be captured.

  The date of creation of the document, the name of the creator, and the like are information normally described in the document. According to the present invention, information related to the content of such document is added to the image information as identification information. Therefore, the user can easily retrieve and read desired image information.

The multi-function machine (an example of a document management system) includes a document management device A according to an embodiment of the present invention, which will be described in detail later, whereby the scanner unit X (an example of an image reading device). The image information of the document read by the above is classified, and the file name of the image information is edited (specific example of giving identification information) and stored.

Here, as shown in FIG. 1, the scanner unit X includes an ADF unit α1 and an image reading optical unit α2. Hereinafter, the ADF unit α1 and the image reading optical unit α2 will be described separately.
The ADF unit α1 includes a document setting unit 1, a conveyance roller 2, a document placing table 3, a document discharge unit 4, and the like. When a predetermined image reading operation is input from an operation panel (see FIG. 3), which will be described later, provided on the exterior of the multi-function machine, the document S set on the document setting unit 1 passes through a plurality of conveying rollers 2. Are sequentially conveyed one by one. The document S conveyed by the conveyance roller 2 is conveyed in the sub-scanning direction through a predetermined reading position on the document reading table 3 made of, for example, platen glass or the like, and then discharged to the document discharge unit 4. .
On the other hand, the image reading optical unit α2 includes the exposure device 5, the light guide mirrors 6a to 6c, the imaging lens 7, the CCD 8, the document management device A, and the like. The document management apparatus A includes a CPU 9 as a calculation unit, a storage unit 10 and the like. The exposure device 5 irradiates light onto the document S moving in a sub-scanning direction at a predetermined reading position of the document table 3. This light is scanned on the document in a scanning direction orthogonal to the sub-scanning direction. The reflected light from the document S is guided by the light guide mirrors 6 a, 6 b, 6 c and is collected by the imaging lens 7. Further, the CCD 8 (optical sensor) converts the image information contained in the reflected light into an electrical signal and inputs it to the document management apparatus A. In the document management apparatus A, the image information is classified in detail as will be described later, and the file name is edited (given identification information) and stored in the storage unit 10.
In addition to the scanner unit X, the multi-function machine has a printer unit that prints the image information on printing paper. The printer unit is a document management apparatus A according to an embodiment of the present invention. Since it has nothing to do with the features of, its explanation is omitted.

(2) Feature points, identification elements, and identification information of the document management apparatus according to the embodiment of the present invention.
The document management device A classifies the image information of the document read by the scanner X (image reading device), and edits and stores the file name of the image information (specific example of giving identification information). In that respect, it is different from the conventional example.
Hereinafter, an example of storing image information of the document 200 in which the date 201, the person-in-charge 202, and the approver mark 203 are arranged at specific positions on the document as shown in FIG. 2 will be described.

The document management apparatus A extracts the date 201, the person-in-charge mark 202, and the approver mark 203 described at predetermined positions on the document 200 from the image information of the document 200 as shown in FIG. Based on these, the image information of the document 200 is classified.
Here, the concept information used for classification of the document 200 or editing of the file name (addition of identification information) such as the date 201, the person-in-charge 202, the approver mark 203, etc. is referred to as an identification element.
Further, individual information as a specific example included in the identification element as a concept as described above is referred to as identification information. For example, the concept of date, which is an example of the identification element, includes specific dates (specific numerical values) such as January 10, 2004, October 23, 2005, and 05/11/21. There may also be a case where a specific name is included as identification information in the concept (identification element) of the person in charge.
In this example, the identification information is a description of a specific example (specific information) of the identification element as a concept, but the present invention is not limited to this, and the identification element Is another expression of the identification information given to the image information, and the identification element may be converted into the identification information. For example, the identification information is used as a specific address, the postal code is used as the identification element, the address is specified from the read postal code, and the specified address is assigned to the image information.

FIG. 6 is a flowchart showing processing procedures in the first and second steps executed by the CPU 9 (computer) of the document management apparatus A. Among them, FIG. 6A shows a processing procedure in the first step. In the first step, the identification element (date 201, person in charge 202, approver mark 203) on the document 200, each of the description area position information and the correspondence between the identification element, and the identification element This is a step for storing the correspondence relationship with the identification information (specific names of the person-in-charge 202 and the approver mark 203) in the storage unit 10 in advance. This is a process executed at the time of initial setting of the machine.
On the other hand, FIG. 6B shows a processing procedure in the second step. The second step uses the correspondence information stored in the first step from the image information of the document 200, and uses the corresponding information stored in the first step to uniquely correspond to the identification element. And specific names for the date 201, specific names for the person-in-charge 202, and specific names for the approver-mark 203 (the specific information is the identification information) are extracted (an example of generation). Process. The second step is a step that is executed every time the image information of the document 200 is read from the scanner unit X.
Hereinafter, the first step and the second step will be described in detail with reference to FIGS. 6 (a) and 6 (b).

(3) About the first step.
FIG. 4 is a schematic view of an operation panel provided on the exterior of the multifunction machine including the document management apparatus according to the embodiment of the present invention. With reference to FIG. 4, the operation panel provided on the exterior of the multifunction machine and the template capture mode set in the first step will be described.
Here, the template capture mode is switched and set by an operation input from the operation panel formed on the appearance of the multifunction machine as follows.
The multi-function machine has various modes corresponding to functions of a copying machine, a scanner, a facsimile machine, etc., which operate the copy key 401, scanner key 402, and FAX key 403 on the operation panel 400 shown in FIG. It is switched by input. In addition, the multi-function machine can set printing magnification, paper type, and character / photo printing corresponding to the magnification key 404, paper selection key 405, and character / photo. It is set by an operation input of the photo key 406. The setting contents are displayed on the display unit 407.
The operation panel 400 is provided with a template capture key 408. By the operation input of the template capture key 408, the multi-function machine is switched to the template capture mode for specifying the position information of the identification element. Hereinafter, the first step will be described.

Each step S1, S2,... In FIG. 6A represents the number of the processing procedure in the first step, and starts from the processing in step S1 when the template capture mode is set. Each of the steps can be executed by the scanner unit X, the CPU 9, the storage unit 10 and the like as follows.
In step S1, a template image 300 as shown in FIG. 3 is read. At this time, specific image specific images 301 (rectangular images) and 302 (circular images) corresponding to the arrangement of each of the identification elements (the date 201, the person-in-charge 202, and the approver mark 203) in the document 200 Image) and 303 (composite image of a circle and a straight line) are read from the scanner unit X1 together with position information on the arranged template document 300.
In step S2 following step S1, the specific image 301 (rectangular image), 302 (circular image), 303 (circular and straight composite image) and their description area (from the image information of the template document 300) The correspondence relationship with the position information of the date 201, the person-in-charge mark 202, and the description area of the approver mark 203 is automatically determined by analysis using graphic recognition by the CPU 9.
In step S3 following step S2, the type of the specific figures 301 to 303 determined in step S2 and the position information of the description area (of the date 201, the person-in-charge 202, and the approver-mark 203) Are stored in the storage unit 10.
In step S4 following step S3, a correspondence relationship between each of the specific figures 301 to 303 and the identification element (concepts such as the date 201, the person-in-charge 202, and the approver-mark 203) is input and stored. . As for the storage of the correspondence relationship, when the correspondence relationship between each type of the specific figures 301 to 303 and the type of the identification element is input to the storage unit 10 in advance as a specified one, or A case where the operator inputs the type of the identification element for each of the specific figures 301 to 303 while displaying the image information of the template image 300 on a display or the like can be considered.
As described above, the three identification elements (the date 201, the person-in-charge 202, the above-mentioned information related to the position information of the description area specified on the document 200 and the identification information given to the image information of the document 200 are described. The correspondence relationship with the approver mark 203) is stored in the storage unit (an example of a description area correspondence storage unit).
As described above, the position information of the description area is specified by the CPU 9 (an example of position information specifying means) based on the image information of the template document 300 on which the specific images 301 to 303 are arranged. It is. In the second step in the future, the description area on the document 200 is treated as an extraction target area from which the identification information is extracted (generated).
The above steps S1 to S4 are an example of the description area correspondence storage process.
The procedure of S4 described above is a procedure for associating concepts such as “date” and “person in charge” with graphic types such as “rectangle” and “circular” so that the operator can easily understand. Since the types of images such as “circle” and the concepts of “date” and “person in charge” have a one-to-one correspondence, the types of images such as “rectangle” and “circular” can also be regarded as identification elements. For a computer, this way of grasping is rather reasonable. In this case, the associating step of S4 can be omitted.

In the subsequent step S5, by the user's manual input, specific names for the person-in-charge mark 202 and the approver mark 203 (an example of a part of the identification element), that is, the identification information related to the identification element and And the CPU 9 stores the corresponding relationship in the storage unit 10 (an example of an identification element information correspondence storage unit). (For example, the identification information for the person-in-charge mark 202 is considered to be the name of an employee at the office where the multifunction machine is installed).
Further, as shown in FIG. 5, a main directory 501 is formed for each specific name corresponding to the person-in-charge mark 202 in the storage unit 10, and each approver mark 203 is stored in each main directory 501. A subdirectory 502 is formed for each specific name corresponding to (specifically, the name of the approver). When step S5 is finished, the first step is finished.
For a concept such as a date in which the candidate cannot be specified in advance, a rule that adopts the character itself recognized in the image area as identification information each time is stored. Such information includes “zip code”, “sender address”, “sender name”, etc. when the document is a postcard.

(4) About the second step.
Each step S101, S102... In FIG. 6B represents the number of the processing procedure in the second step, and is started from the processing of step S1 when setting the mode (scanner mode) corresponding to the function of the scanner. The Each of the steps can be executed by the scanner unit X, the CPU 9, the storage unit 10 and the like as follows.
In step S101, image information of the document 200 such as an actual form is read by the scanner unit X.
In step S102 following step S101, the CPU 9 (an example of an identification element extraction unit) refers to the correspondence stored in step S4 of the first step in the storage unit 10 (description area correspondence storage unit). , Image information of the description area corresponding to the position information analyzed (identified) in step S2 is extracted. As described above, the extracted image information can be identified with the identification element.
Step S102 is an example of the identification element extraction process.
In step S103 following step S102, character recognition is applied to the image information extracted in step S102 by the CPU 9 (an example of an identification information addition storage unit). Accordingly, from the identification elements (specifically, image information of the description area) such as the date 201, the person-in-charge 202, the approver mark 203, etc., “2004/08/26”, “Kawada”, “Yamada” Are extracted (an example of generation).
As described above, the correspondence between each position information of the description area and the type of the identification element (for example, the description area obtained from the coordinates of the rectangular image 301 includes the date of the identification element. 201 corresponds, etc.) is stored in the storage unit 10, and based on this stored information, the type of character recognition applied to the extracted image information, that is, a number is extracted or a kanji is Whether to extract is determined in advance. For example, only numbers are extracted from the extracted image information for the date 201, and only characters excluding the stamp value are extracted from the person-in-charge mark 202 and the approver mark 203. For example, kanji characters “Kawada” and “Yamada” are extracted from the person-in-charge mark 202 and the approver mark 303 in the example of FIG.

In step S104 following step S103, the CPU 9 (an example of identification information addition storage unit) and the identification element and the identification stored in the storage unit 10 (an example of identification element information correspondence storage unit) in step S5 described above. While referring to the correspondence with the information, the document 200 for each specific name (part of identification information) for the person-in-charge mark 202 and the approver mark 203 among the identification elements extracted in step S103. Image information is classified. Further, the file name of the image information is edited based on a specific numerical value for the date 201 (that is, identification information is given). In this case, the identification information is used as classification information for classifying the image information of the document 200.
That is, the specific names for the person-in-charge 202 and the approver name 203 extracted in step S103, and the specifics for the person-in-charge 202 and the approver name 203 stored in the storage unit 10 in step S5. The target name is collated one by one by the CPU 9 (an example of collation means). Based on such collation, when the extracted specific name matches with any of the specific names stored in the storage unit 10 (establishment of step S104), the extracted name The information is stored in a directory corresponding to specific names of the person-in-charge 202 and the approver-mark 203, and the second step is completed. The specific numerical value extracted (an example of generation) from the date 201 is used as a part of the file name of the image information stored in the storage unit 10.

It should be noted that the specific names (identification information for the identification elements) of the person-in-charge mark 202 and the approver mark 203 extracted in step S103 are stored in advance in the storage unit 10 (an example of identification information element correspondence storage means). When the collation is not established with any of the specific names (identification information), the process proceeds to step S105.
In step S105, the correspondence relationship between the identification elements such as the person-in-charge mark 202 and the approver mark 203 and the new identification information (specific names extracted in step S103) corresponding thereto is the CPU 9 (candidate registration means In one example, the data is additionally stored in the storage unit 10. Correspondingly, the subdirectory 502 (or both the main directory 501 and the subdirectory 502) is created.
For example, when “Kawada” is extracted as the specific name of the person-in-charge mark 202 and “Kikuchi” is extracted as the specific name of the approver mark 203, in the example of FIG. On the other hand, the identification information “Kikuchi” is not stored in the storage unit 10. In this case, “Kikuchi” is stored in the storage unit 10 as identification information corresponding to the approver mark 203. In addition, a subdirectory 502 of “Kikuchi” is created under the main directory 501 of “Kawada”.
Steps S103 to S105 are the identification information adding and storing step.
As described above, the image information of the document 200 is extracted from the image information by the document management apparatus A according to the embodiment of the present invention (the date 201, the person-in-charge 202, the approver). Since the classification information is stored based on the identification information (specific numerical value, specific name) generated based on the mark 203), the user can easily retrieve and read desired image information based on such classification. Is possible.

In the above embodiment, the storage unit 10 (see FIG. 1) stores the specific names corresponding to the identification elements (the person-in-charge 202, the approver mark 203, see FIG. 2), and the stored names When a specific name that does not correspond to any of the specific names is extracted (when the collation in step S104 is not established), the identification element (the person-in-charge mark 202, the approver mark 203) and the identification element Although an example of adding and classifying a correspondence relationship with new identification information (specific name) is disclosed, it is not limited to this.
That is, “other” is provided as the main directory 501 created in the storage unit 10, and if the identification information does not correspond to any of the storage contents of the storage unit 10 as described above, It is conceivable to store the image information from which the identification information is extracted in the “other” directory.
It is also conceivable that the image information from which the identification information is extracted is discarded without being stored, and a predetermined error output sound is output from the audio output unit accordingly. With such a configuration, for example, when the image information of a document for which the person in charge is forgotten to be pressed is read, the user can be alerted that there is an unfilled portion in the document.

In the above-described embodiment, the multi-function machine having the image information storage function has been described as an example. However, the present invention is not limited to this. For example, a scanner and a personal computer are connected to each other. The present invention is also applied when image information of a read document is managed by the hard disk of the personal computer.
In this case, it is necessary to store (install) a document management program that causes the personal computer to execute each of the first to second steps.

In the above-described embodiment, the example in which the template image in which the specific images 301 to 303 are described is read by the scanner unit X (see FIG. 1) in order to specify the position information of the identification element description area has been described. It is not limited to this.
That is, an example in which the description area of the identification element is stored in the storage unit 10 by a user's manual input is also conceivable.
Further, the template image is a document on which characters such as “A”, “B”,... Are written, even if the rectangular image 301, the circular image 302, etc. (see FIG. 3) are not described. May be. In this case, the document management apparatus according to the embodiment of the present invention extracts characters such as “A” and “B” by character recognition, and specifies the description position information of the extracted characters as the position information of the description area.
In addition, various modifications can be adopted as long as the gist of the present invention is not deviated.
