The search code may be a cabinet name, binder name, document title, or the like.

Further, in the storage address storage area B, as shown in the figure, the track number T-ADR and the sector number 5 are stored as the image data start address of 1 image storage sector on the optical disc 19 for the image information corresponding to the direct number. A storage address consisting of -ADR and image size S is stored.

Next, the operation in such a configuration will be explained.

First, registration (storage) of image information will be explained. Registration mode is selected and set using the keyboard 23, and a search code for image information to be registered is entered.

As a result, the CPU 12 checks the validity of the input data based on the number of digits, character type, etc. according to the predefined search code format (cyclic redundancy check, CR
C) and check the search codes that have already been registered to ensure that there is no double registration.
As a result of these checks, if the search code is overwhelming, it is stored in the main memory 13. Then, the original is set on the two-dimensional scanning device 20, and the CPU 12
and operate the two-dimensional scanning device 120. The two-dimensional scanning device 20 two-dimensionally scans image information such as a set document and performs photoelectric conversion. This photoelectrically converted line information is sequentially stored in the page buffer 14. When one page of image information is stored in this page buffer 14, the image information is stored in the display interface 17,
The image information is displayed on the CRT display device 24. By the way, if the image displayed on the CRT display device 24 is satisfactory, a recording key (not shown) is turned on. Then, the CPIJ12 compresses the band of one unit of image information stored in the page buffer 14 for each line of information using the well-known MH (Modifier-Hoffman) conversion in the compression/expansion circuit 15, and converts the compressed line information into optical data. The data is supplied to the disk device 22. Thereby, the optical disk device 22 stores the supplied image information on the optical disk 19.

When the storage of this image information is completed, the CPU 12 stores the storage address, such as the track number where the image information is stored, the starting sector, and the length of the image, in the main memory 13 in correspondence with the search code. Next, the CPU 12 supplies the search data stored in the main memory 13, that is, the search code, track number, image length, etc. (or cabinet name, binder name, document title, etc.) to the magnetic disk device 27. Thereby, the magnetic disk device 27 stores the supplied search data in the search data storage area 28b of the magnetic disk 28. That is, the search code of the search data is stored in the search code storage area A, and the storage address is stored in the storage address storage area B. Thereafter, other image information is stored on the optical disk 19 in the same manner.

On the other hand, the search for image information registered as described above will be explained with reference to the flowchart shown in FIG. First, a search mode is selected and set using the keyboard 23, and a floppy disk 30 on which a plurality of search data is recorded in advance by a personal computer (not shown) is transferred to the floppy disk device 29.
Insert into. Then, a start key (not shown) is input. Then, the floppy disk device 29 searches for the first search output data and converts the search output data into C.
Output to PIJl2. As a result, the CPU 12 sequentially compares matching search information with the search information stored in the storage area 29b of the magnetic disk 29 based on the cabinet name, binder name, document title, etc. as search information in the supplied search output data. Verify. If they match, the CPIJ12 causes the optical disk device 22 to play back the corresponding track on the optical disk 19 based on the cabinet name, binder name, document title, page number, etc. Then, the CPU 12 supplies the image information from the optical disk device 22 to the compression/expansion circuit 15 for each scanning line, performs band expansion by inverse MH conversion, and sequentially supplies the original image information to the page buffer 14. In this way, Begebuff? When all the image information for one page reproduced in the computer 14 is stored, the CPU 12 displays it on the CRT display device 24 and causes the recording device 25 to issue hard copies 26 of the image information for a specified number of schools.

At this time, if there is additional information, such as an add-on, in the search output data, the CPU 12 converts the character string into a character pattern using the pattern generator 16, and stores the specified position (coordinates) of the reproduced page of image information in the page buffer 14. ) and then issue the hard copy 26.

Further, after the above printing, CPIJl stores the processing results in the corresponding search output data storage area a of the floppy disk 30.

Thereafter, the CPU 12 operates in the same manner as described above for the search information sequentially read from the floppy disk 30, thereby sequentially obtaining hard copies of the corresponding image information.

Then, when all search outputs are completed, CPL11
Step 2 automatically prints the results and ends the process. It can also be interrupted by an operator's command.

In this way, the search data input operation and the actual search processing can be separated, and the time required for operator intervention can be reduced. Also, the operator sometimes
While monitoring on a display device, it can be interrupted or restarted at will.

In the above embodiment, the search output data is stored on a floppy disk, but it may be stored directly on an optical disk or a magnetic disk. In this case, it is effective for fixed and repeated searches.

[Effects of the Invention] As detailed above, according to the present invention, input of search data and actual search processing can be separated, and the time spent occupying the device due to operator intervention can be reduced. An information retrieval device can be provided.
