The printer device 25 prints out (hard copy) image information read by the scanner device 18, image information retrieved from the optical disk 20, or image information displayed on the CRT display device 24.

The magnetic disk device 27 is an optical disk that stores various control programs on a magnetic disk 26 mounted on the magnetic disk device 27, and also stores search information manually entered from the keyboard 23 and image information corresponding to this search information. 2o, search data consisting of storage address, image size, search frequency, etc. is stored.

The above search data is managed by a document management table, which includes a title management table 26a, a page management table 26b, and an ID management table, as shown in FIG. 26c
It is made up of.

In the title management table 26a, one document number is stored corresponding to each piece of search information (image name) consisting of a plurality of search keys. The page management table 26b stores record numbers for each page of one document, and one record number is stored for each page. In the record management table 26c,
For each record number, the storage address (storage start position) of the image information on the optical disk 19, document size (image size), image attributes such as compression method and resolution, and search frequency (access frequency) are stored.

The search frequency indicates the number of times image information has been searched, and is updated every time the image information is searched. That is, each time a search for image information is performed, the CPU 34 increments the search frequency in the search data by "+1". For example, if the search frequency for one page shown in FIG. 2 is "10", when that image is searched, the frequency is updated to "11" and stored.

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 document management system in this embodiment has four levels: cabinet, binder, and document page, and the cabinet corresponds to one side of the optical disc 19. Up to eight binders can be defined in a cabinet, and up to 30,000 documents can be stored in a binder. Each document has a title, and its structure is defined for each binder. The above document is the basic unit of a file, and in addition to the title, annotations (explanation of the document) can be added. Further, a document is composed of up to 4095 pages.

Next, the operation of image information storage and retrieval processing in the electronic filing device with such a configuration will be described. First, storage processing of image information will be explained.

For example, the user selects and sets the registration mode using the keyboard 23 and manually searches for image information to be stored on the optical disc 20.

This search information is composed of a plurality of search key items, and the contents of the search key items are set in advance. The CPU 34 checks the validity of the input search information according to a predefined format. Further, the search information is compared with the search information already registered on the optical disc 20 to check for double registration. The input search information is stored in the main memory 13 according to the result of this check.

Next, the original is set on the scanner device 18, and the CPU 34
operates the optical disk device 22 and scanner device 18. The scanner device 18 two-dimensionally scans and photoelectrically converts image information such as a set document. Line information of this photoelectrically converted image information is sequentially stored in the page memory 40.

The image information stored in the page memory 40 is stored in the display memory 42 and displayed on the CRT display device 24. The user checks the skew, density, resolution, etc. of the image information displayed on the CRT display device 24, and when the displayed image information is satisfactory, inputs a memory key (not shown). Then, the CPU 34 converts the image information stored in the page memory 40 into a well-known M R
Encoding processing is performed by band compression using a (Modified Read) method or the like. This encoded image information is supplied to the optical disc device 22 and stored on the optical disc 20.

When the image information has been stored on the optical disk 20, the CPU
34 is a search code (a search code (
search information) and stored in the main memory 38.

Next, the CPU 34 supplies the search data stored in the main memory 38 to the magnetic disk device 27. Thereby, the magnetic disk device 27 stores the supplied search data in the magnetic disk 26.

Next, the search process for image information stored on the optical disc 20 will be explained with reference to the flowchart shown in FIG. First, a search mode is set using the keyboard 23, and search information corresponding to the image information desired to be searched is input. The CPU 34 sequentially compares and collates the input search information with the search information stored in the title management table 26c of the magnetic disk 26, and sequentially checks whether or not search information that matches the input search information is stored. and extract the corresponding document number. And CPU34
displays a list of relevant documents (search information) using the CRT display device 24.

Based on this display, if the document for which the operator is being searched for is not found, the user re-enters the search information. If found, specify the document from the list (enter the display document number)
and instructs to execute the search.

The CPU 34 stores the page management table 26 of the magnetic disk 26.
All pages having the corresponding document number b and their record number information are extracted, and information corresponding to each record number is extracted from the record management table 26c. This allows the CPU
34 is stored on the main memory 38 as shown in FIG.
A record table of the same document number consisting of page number, logical address, image length, image attribute, and search frequency is created (sorted) in descending order of search frequency.

In this case, the record with the highest search frequency corresponds to the top of the record table, and when the search frequencies are the same, the record with the smallest page number is set.

Then, the CPU 34 reads the logical address corresponding to the record with the highest search frequency, calculates the physical track address and physical sector address corresponding to this address, and uses these addresses to optically control the reproduction of image information from the optical disk 20. This is done by the disk device 22. Also, CPU
34 supplies the image information (compressed information) for each scanning line supplied from the optical disk device 22 to the compression/expansion circuit 50, performs band expansion processing, and sequentially supplies it to the page memory 40. The image information stored in this page memory 40 is
The image is displayed on the CRT display device 24 using the display memory 42.

In addition to the above image, CR also provides guidance on specifying the display page.
It is displayed on the T display device 24.

In response to the above guidance, the operator inputs the display page number corresponding to the desired page. When the same display page number as the above display image is input, the CPU 34 performs the above search process (display process) in the record management table 26c of the magnetic disk 26.
Update processing is performed to increment the search frequency corresponding to the page for which the search has been performed by "+1".

Also, if a display page number different from the image above is entered,
The CPU 34 reads the logical address corresponding to the input display page number, calculates the physical track address and physical sector address corresponding to this address, and uses these addresses to control the reproduction of image information from the optical disk 20 by the optical disk device. It will be held at 22. Further, the CPU 34 supplies image information (compressed information) for each scanning line supplied from the optical disk device 22 to the compression/expansion circuit 50, performs band expansion processing, and sequentially supplies the image information to the page memory 4o. The image information stored in this page memory 40 is stored in the display memory 4
2 to be displayed on the CRT display device 24.

When this display is performed, the CPU 34
Update processing is performed to add "+1" to the search frequency corresponding to the page on which the above search processing has been performed in the record management table 26c.

” - When the image information displayed on the CRT display device 24 is instructed to print out using, for example, the keyboard 23, it is supplied from the page memory 40 to the printer device 25 via the printer interface 54, and from this printer device 25. It will be printed out. At this time, necessary processing such as image editing can be performed by the scaling circuit 46, the vertical/horizontal conversion circuit 48, and the like.

As described above, during a search, the most frequently searched pages within the specified document are displayed first. As a result, the search frequency is respected during the search, pages that are frequently searched can be displayed first, and operability can be improved.

In the above embodiment, when the first displayed image is the search target, the display page number is input. However, the present invention is not limited to this, and the display page number may not be input. Also good. In this case, the search frequency is updated based on which image was used for the search in response to the end instruction.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an information retrieval device that respects retrieval frequency during retrieval, can output image information with high retrieval frequency first, and has good operability.
