Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention registers document data consisting of image data (image data), character data (code data), graphic data (vector data) and the like in a large capacity storage medium such as a magneto-optical disk. The present invention relates to an electronic filing device that calls and displays or prints arbitrary data of registered document data.

[0002]

2. Description of the Related Art In a conventional electronic filing apparatus, search conditions such as a document name and a document number added to a desired document are designated and displayed or printed. Further, when it is desired to output a certain page in the document, the desired page is designated and displayed or printed.

Further, an electronic filing apparatus (for example, Japanese Patent Laid-Open No. 63-173162) which extracts only necessary memory information of a document, page, or revised version from the memory device by using management information packed in a document box. (See the gazette).

[0004]

However, in the conventional electronic filing apparatus, the content of the document must be judged from the very limited information such as the document name and the document number, and when the number of documents is small, only that is required. Although it may be possible to make a judgment based on the information described above, when a large number of registered documents are used, the judgment based on only the information such as the document name may cause the document to be erroneously output.

In order to prevent such a situation, it is necessary to display the document data once on the display device and then judge the content of the document. It becomes less efficient.

Further, when it is desired to output only the data of several discontinuous pages from one document, the document data is once displayed on the display device to determine the required page, and the individual pages to be output are respectively output. It had to be specified and output, which was very inefficient and time-consuming.

Further, when it is desired not to output only the data of several discontinuous pages from one document, the document data is once displayed on the display device to judge unnecessary pages, and only the necessary pages are individually or individually displayed. Each had to be specified and output, which was extremely inefficient and time-consuming. Furthermore, printing unnecessary pages when printing the data of one document wastes paper.

As described above, even if only the required document, page, or revised storage information is extracted from the storage device using the management information, the operation of designating the desired document or page data is still possible. It was necessary, so it was difficult to output it quickly. Therefore, there is a problem that it is difficult to output the desired document or page data quickly and efficiently.

The present invention has been made in view of the above points, and it is an object of the present invention to output necessary document or page data by a simple operation.

[0010]

In order to achieve the above object, the present invention provides a registration means for registering document data composed of image data, character data, graphic data, etc., and document data registered in the means. In an electronic filing device equipped with a printing means for printing, a specific character / image adding means for adding a specific character or a specific image to registered document data in document or page units, and recognizing a specific character or specific image at the time of printing The specific character / image recognition means and the means for causing the printing means to print only the data of the document or page in which the specific character or the specific image is recognized by the means.

Further, in the electronic filing apparatus equipped with the above-mentioned registration means, printing means, specific character / image adding means, and specific character / image recognizing means,
It is preferable to provide a means for preventing the printing means from printing the data of the document or page in which the specific character or the specific image is recognized by the image recognition means.

Further, in the electronic filing apparatus provided with the above-mentioned registration means and specific character / image adding means, display means for displaying the document data registered in the registration means, and specific characters or specific images are recognized at the time of display. It is preferable to provide a recognition unit and a unit for preventing the display unit from displaying the data of the document or page in which the specific character or the specific image is recognized by the recognition unit.

[0013]

According to the electronic filing apparatus of the present invention, a specific character or a specific image is added to document data in document or page units, and only data of a document or page in which the specific character or specific image is recognized at the time of printing is printed. Therefore, the desired document or page can be printed quickly without having to specify it again.

Further, if the data of the document or page in which the specific character or the specific image is recognized is not printed, it is possible to prevent only the undesired document or page from being printed even if it is not designated again.

Further, if the data of the document or page in which the specific character or the specific image is recognized is not displayed at the time of display, it is possible to prevent only the undesired document or page from being displayed even if it is not designated again. it can.

FIG. 3 is a diagram showing an example of a specific area of a page to which a specific character or a specific image is added. In this way, the specific area 22 for adding the specific character or the specific image is set to the data area 21 for one page of the document data. As the specific area, a predetermined area may be automatically set by the system, or an operator may arbitrarily set the specific area.

FIG. 4 is a diagram showing an example of a specific character. 4A is a specific character 23 added to the data of the document or page to be printed, and FIG. 4B is a specific character 24 added to the data of the document or page not to be printed. c) is a specific character 25 added to the data of the document or page not to be displayed.

FIG. 5 is a diagram showing an example of the specific image. 5A shows a specific image 26 added to the data of the document or page to be printed, and FIG. 5B shows a specific image 27 added to the data of the document or page not to be printed. c) is a specific image 28 added to the data of the document or page not to be displayed.

Such specific characters or specific images may be arbitrarily selected from those prepared in advance, or may be arbitrarily created and set.

Next, the process for printing only specific document data will be described with reference to the flowchart shown in FIG. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When a document to be output is designated at the time of registration or retrieval, the document is specified at an arbitrarily designated location in a specific area saved ahead of the data of the first page of the document designated to be output. Add characters and specific images.

After that, it is judged whether or not the next document is designated, and if there is, the process returns to the designation process of the document to be output again. Thus, in the case of output designation for a plurality of documents, the process of adding a specific character or a specific image in a specific area of the data of the first page of each document is repeated. On the other hand, if the next document is not designated, the output designation process of adding the specific character or the specific image to the specific area of the output document is completed.

Next, when the document is output, the specific character or image previously added to the specific area of the data on the first page of the document is stored in the specific character / image recognition unit 15 and stored in the storage device 5. The data of the first page of the existing document is called and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the data.

In this determination process, for a document determined to have a specific character or a specific image added to the data of the first page, the data of all pages of the document is read from the storage device 5 and printed by the printer 4. Further, the document which is determined that the specific character or the specific image is not added to the data of the first page is not printed.

Then, it is determined whether or not there is a document to be called from the storage device 5, and if there is, the process returns to the process of calling the document again, and only the document in which the specific character or the specific image is added to the data of the first page. Is printed, and if there is no document to be called, this processing ends.

Next, the processing for printing only a specific page of document data will be described with reference to the flowchart shown in FIG. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When a page to be output of a document is designated at the time of registration or retrieval, a specific character or a character is placed at an arbitrarily designated location in a specific area saved ahead of the data of the designated page to be output. Add a specific image.

After that, it is judged whether or not the next page is designated, and if there is, the process returns to the designation process of the page to be output again.
In this way, when the output is designated for arbitrary plural pages of the same document, the process of adding the specific character or the specific image in the specific region of the data of each page is repeated. on the other hand,
If the next page is not designated, the output designation process of adding the specific character or the specific image to the specific area of the page to be output ends.

Next, at the time of outputting the document, the specific character or image previously added to the specific area of the data of the page of the document is stored in the specific character / image recognition unit 15, and the storage device 5
The data of the first page of the document stored in is called, and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the data.

In this determination process, the data of the page determined to have the specific character or the specific image added is printed by the printer 4. Further, the data of the page which is determined that the specific character or the specific image is not added is not printed.

Then, it is determined whether or not there is a next page to be called from the storage device 5, and if there is, the process returns to the process of calling the data of the page, and a specific character or a specific image is added to the data of the next page. It is determined whether or not the page has been added, and in this way, only the data of the page to which the specific character or the specific image of the same document is added is printed,
If there is no page to call, this process ends.

Next, the processing when not printing only specific document data will be described with reference to the flowchart shown in FIG. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When a document which is not to be output is designated at the time of registration or retrieval, the document is specified at an arbitrarily designated location within the specific area saved ahead of the data of the first page of the document which is not to be output. Add characters and images.

Thereafter, it is judged whether or not the next document is designated, and if there is, the process returns to the designation process of the document which is not output again. In this way, in the case of not specifying output for multiple documents,
The process of adding the specific character or the specific image in the specific area of the data of the first page of each document is repeated. On the other hand, if the next document is not designated, the process of designating not to output by adding the specific character or the specific image to the specific area of the document which is not output is finished.

Next, at the time of outputting the document, the specific character or image previously added to the specific area of the data of the first page of the document is stored in the specific character / image recognition unit 15, and the storage device 5
Data of the first page of the document stored in is called and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the data.

In this determination processing, the document determined to have the specific character or the specific image added to the data of the first page is not printed. Further, for a document in which it is determined that the specific character or the specific image is not added to the data of the first page, the data of all pages of the document is read from the storage device 5 and printed by the printer 4.

Then, it is judged whether or not there is a document to be called from the storage device 5, and if there is, the process returns to the process of calling the document again, and only the document in which the specific character or the specific image is added to the data of the first page. Is not printed, and if there is no document to be called, this process ends.

Next, the processing when not printing only a specific page of the document data will be described with reference to the flowchart shown in FIG. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When there is a page designation not to output the document at the time of registration or retrieval, a specific character or a character is placed at an arbitrarily designated location in the specific area saved ahead of the data of the page designated not to be output. Add an image.

Then, it is judged whether or not the next page is designated, and if there is, the process returns to the designation process of the page not to be output again. In this way, in the case of not specifying output for arbitrary plural pages of the same document, the process of adding a specific character or a specific image in a specific area of the data of each page is repeated. On the other hand, if the next page is not designated, the output designation process of adding the specific character or the specific image to the specific area of the page that is not output is completed.

Next, at the time of outputting the document, the specific character or image previously added to the specific area of the data of the page of the document is stored in the specific character / image recognition unit 15 and stored in the storage device 5. The data of the first page of the document is called and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the data.

In this determination process, the data of the page determined to have the specific character or the specific image added thereto is not printed. Further, the data of the page which is determined that the specific character or the specific image is not added is printed by the printer 4.

Then, it is judged whether or not there is a next page to be called from the storage device 5, and if there is, the process returns to the process of calling the data of the page, and a specific character or a specific image is added to the data of the next page. It is determined whether or not the page has been printed. In this way, a process of not printing only the data of the page to which the specific character or the specific image of the same document is added is performed, and if there is no page to be called, this process ends.

Next, the processing when only specific document data is not displayed will be described with reference to the flowchart shown in FIG. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When a document which is not displayed at the time of registration is designated, a particular character or a particular character is designated at an arbitrarily designated place in the particular area saved ahead of the data of the first page of the document which is designated not to be displayed. Add an image.

After that, it is judged whether or not the next document is designated, and if there is, the process returns to the designation process of the document which is not displayed again. Thus, in the case of not displaying for multiple documents,
The process of adding the specific character or the specific image in the specific area of the data of the first page of each document is repeated. On the other hand, if the next document is not designated, the process of designating not to display by adding the particular character or the particular image to the particular area of the document which is not outputted is completed.

Next, when retrieving a document, the specific character or image previously added to the specific area of the data of the first page of the document is stored in the specific character / image recognition unit 15, and the storage device 5
The data of the first page of the document stored in is called and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the image data.

In this determination processing, the document determined to have the specific character or the specific image added to the data of the first page is not displayed. Further, for a document in which it is determined that the specific character or the specific image is not added to the data of the first page, the data of all pages of the document is read from the storage device 5 and displayed on the display 3.

Then, it is determined whether or not there is a document to be called from the storage device 5, and if there is, the process returns to the process of calling the document again, and only the document in which the specific character or the specific image is added to the data of the first page. Is not displayed, and if there is no document to be called, this process ends.

Next, with reference to the flowchart shown in FIG. 11, a process when only a specific page of document data is not displayed will be described. First, an area range to which the specified specific character or specific image is added is specified, and this area range is stored in the specific area buffer 18.

When there is a page designation for not displaying the document at the time of registration or retrieval, a specific character or a character is placed at an arbitrarily designated location in the specific area saved ahead of the data of the page designated not to be displayed. Add a specific image.

After that, it is judged whether or not the next page is designated, and if there is, the process returns to the designation process of the page not to be displayed again. In this way, when it is designated not to display arbitrary plural pages of the same document, the process of adding the specific character or the specific image in the specific region of the data of each page is repeated. On the other hand, if the next page is not specified, the output specifying process of adding the specific character or the specific image to the specific area of the page that is not displayed ends.

Next, when searching for a document, the specific character or image previously added to the specific area of the data of the page of the document is stored in the specific character / image recognition unit 15 and stored in the storage device 5. The data of the first page of the document is called and it is determined whether a specific character or a specific image is added to the area corresponding to the specific area stored in the specific area buffer 18 of the data.

In this determination processing, the data of the page determined to have the specific character or the specific image added is not displayed. Further, the data of the page determined to have no specific character or specific image added is displayed on the display 3.

Then, it is judged whether or not there is a next page to be called from the storage device 5, and if there is, the process returns to the process of calling the data of the page, and a specific character or a specific image is added to the data of the next page. It is determined whether or not the page data is displayed, and in this way, the process of not displaying only the data of the page to which the specific character or the specific image of the same document is added is performed, and if there is no page to be called, this process is terminated.

Next, a specific processing result of printing and displaying document data in document units in this electronic filing apparatus will be described.
