Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic filing device such as an image information storage and retrieval device that registers or searches image information.

(Prior art) In recent years, scanners (
A two-dimensional scanning device) reads the image information, stores the read image information on an optical disk, searches for any stored image information, reads it out, and outputs it to an output device, such as a CRT display, so that it can be viewed visually. Electronic filing devices have been put into practical use.

Such devices manage image information for multiple pages of a document or the like on a document-by-document basis.

Now, some electronic filing devices that manage image information on a document-by-document basis have a document management system of four levels, for example, cabinet, binder, document, and page, and each cabinet is associated with one side of an optical disc.

Furthermore, devices have been developed that allow the setting of a secret code to protect the confidentiality of registered documents and prevent the contents of documents in a binder from being changed.

This type of secret code includes, for example, a secret code attached to a binder and a secret code attached to a cabinet.
The secret code attached to the binder is further divided into a search secret code and a generation secret code. Among the secret codes attached to binders, the search secret code is a code that prevents anyone who does not know the secret code from searching the documents in the binder, that is, it is a secret code for "search" in the filing process. The generated secret code is a code that prevents anyone who does not know the secret code from registering documents in the binder or changing the contents of already registered documents.
, "Add", "Title correction/addition", "Delete", etc.The cabinet secret code corresponds to a mask key that can be used for all binders in the cabinet.

However, in the case of the electronic filing device mentioned above,
Since the minimum unit for which a secret code can be set is a binder unit, documents that do not require confidentiality protection cannot be registered in a binder with a secret code set.All documents in a binder with a secret code set are protected by that secret code. The drawback was that it could only be managed by

(Problem to be solved by the invention) As described above, in the past, documents that do not require security protection cannot be registered in a binder that has been set with a secret code, and documents in a binder that has been set with a secret code cannot be registered with the secret code. The drawback was that it could only be managed by

Therefore, an object of the present invention is to provide an electronic filing device that can manage documents that need to be kept confidential on a document-by-document basis.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the electronic filing device of the present invention includes a storage means for storing image data in document units, and a storage means for storing image data in document units. It consists of an adding means for adding a secret code to a stored document, and a management means for managing the document using the secret code added by the adding means.

(Function) This invention enables the security code to be set for each document by the above-described means, so that the security can be managed for each document within the binder.

This search/display data is read from the optical disc 19 and stored when the previous disc 19 is loaded.

Second, the storage address is a logical address, from which a physical track address and a physical sector address are calculated at the time of access.

The magnetic disk device 28 is, for example, a 5.25-inch floppy disk device, and stores text files (documents) created with a word processor (not shown), CAD drawing files created with a personal computer (not shown), and worksheet files (drawing data). ), etc., from the floppy disk 28a.

As the floppy disk 28a, various OS (
(operation system).

FIG. 4 shows the document management system in this embodiment.

i.e. cabinet, binder, document, page 4
It has a hierarchy, and each cabinet is associated with one side of the optical disc 19.

A maximum of 8 binders can be defined in a cabinet, and up to 30,000 documents can be registered in a binder. Each document has a title, and its structure is defined for each binder.

The above document is the basic unit of the file, and in addition to the title,
Dates, annotations (document descriptions), and confidential codes can be added. Further, a document is composed of up to 4095 pages (image data).

Such a management system takes into consideration consistency with paper files, and a page corresponds to one paper file (manuscript). In other words, the above page contains the image data of one paper file and the data of one floppy disk (
The data can be either volume data (volume data), single file data, or data that is a combination of the above three types.

As a result, for example, in one document, the source file (code data) of a given program is displayed as the first page.
, the second page is the program specifications (coat data) created with a word processor, and the third page is the processing results (image data). Can be managed well.

FIG. 5 shows an outline of the data area in the search/display data.

In this embodiment, a title area is provided for each document.

In addition to the date area, annotation area, etc., for example, a 16-byte confidential code area is provided. This secret code area is used to write a secret code consisting of, for example, alphanumeric characters, katakana, special symbols, etc., which is set by the keyboard 23 when it is necessary to protect the confidentiality of the document.

Therefore, without setting the secret code of the binder,
When a document's confidentiality code is set, confidentiality can be managed on a document-by-document basis.

Next, the operation in the above configuration will be explained.

FIG. 1 shows an example of the operation when registration processing is selected by the operator.

For example, assume that the operator specifies document registration processing. In other words, "
While information such as ``1: Search'', ``2: Registration'', ``3: Delete'', ``4: Modification'', and ``5: Maintenance'' is displayed, select ``2: Registration'' using the keyboard 23 or mouse 29. Suppose that is selected.

Then, first, a screen for inputting a secret code (generated secret code) is displayed on the CRT display 24. When it is necessary to set a secret code for this display, that is, when it is necessary to protect the confidentiality of the document to be registered, the secret code is input from the keyboard 23.

The input secret code is checked for validity. It is then determined whether there is any overlap with the confidential code of other documents that have already been registered. In this case, the search/display data is read by loading the optical disc 19,
The data is written to the magnetic disk 27a. Also, this search
Display data is transferred to magnetic disk 2 by opening the binder.
7g is sent to the main memory 13. Then, the secret code entered from the keyboard 23 and the main memory 13
The CPU 12 compares the secret code of the document stored therein, thereby checking the secret code.

After this, the document registration work is executed. That is, first, the title registration table (registration condition input table) for inputting the title and search key for the document to be registered is C.
displayed on the RT display 24. In this registration condition input table, fields for displaying the cabinet name and binder name to be registered and a title key list are displayed, and the title of the document to be registered is displayed next to the corresponding title key. You can input each.

Furthermore, after inputting the title of the document in the title registration display and setting multiple originals constituting one document on the scanner 20, when the function key "Execute registration" is pressed, the scanner 20 starts reading the image data. be done.

In this way, the read image data is written to a predetermined location on the optical disk 19 according to the logical address on the one optical disk where the image data is to be stored.

Further, search information and document titles for this image data are sent to the magnetic disk unit W27 as search/display data constituting a database, and are finally stored in the optical disk 19.

In this way, the image data of the second and subsequent pages are registered in the same manner. The registration process ends when the final page of image data, for example image data corresponding to the last document set in the scanner 20, is written onto the optical disc 19.

FIG. 2 shows an example of the operation when the search and display process is selected by the operator.

For example, assume that the operator selects the information "1: Search" displayed on the CRT display 24.

Then, an inquiry is made as to which document to search. That is, the binder names defined in the optical disk 19 are read out and a list thereof is displayed on the CRT display 24. When the operator specifies a binder number using the keyboard 23 or mouse 29 in response to this display, the document title structure of this binder is determined, and the registered document titles are displayed on the CRT display 24.

Now, when the operator selects a target document and instructs to start a search, if a secret code (search secret code) is required, the operator is prompted to input it. Then, the operation is started (executed) only when the input secret codes match. That is, the security code is checked in the same manner as in the registration described above, and if the security code matches the security code of the selected document, that document is read from the optical disk 19 and displayed on the CRT display 24.

In addition, in the case of deletion, the same process as in the above-mentioned search is performed.

As mentioned above, it is possible to set a confidential code for each document.

That is, the secret code is not set for the binder, but is set for each document in the binder.

This makes it possible to manage confidentiality on a document-by-document basis. Therefore, documents that require security protection and documents that do not require security protection can be registered in the same binder, or each document in the same binder can be managed using different security codes.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As detailed above, according to this invention, a security code can be set for each document. We can provide filing equipment.
