Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an image information recording and retrieval device for recording and reproducing information such as images or documents, and particularly to an image information recording and retrieval device.

Regarding the recording of search information and the search method, organizing and filing documents, etc. is the most basic of information management, and a simple method is to rewrite the contents of documents, etc. and record them into files. without inputting
It is common practice to file image information as it is viewed. For example, the most elementary method and
There is a method of binding documents as they are in a binder for each category, but if a larger quantity and high-speed retrieval are required, use an image information storage means such as microfilm, for example, and use an appropriate image storage means. A method is used in which document images are stored and stored at a specific address, and the document image is mechanically retrieved by specifying that address as needed.

Recently, attention has been focused on the large capacity of optical video discs, and devices have been developed that allow image information such as documents to be recorded on discs and information to be retrieved at high speed.

Various locations have also been proposed. This device records image information such as documents on an optical disk, information for retrieval is recorded in a file classification table for storage, and information for retrieval is recorded on a separate floppy magnetic disk. are categorized.

FIG. 1 shows an example of the latter device. The control device 4 activates the input device 1 in response to commands from the keyboard 6, which are set in the input device 1, which is configured similarly to a facsimile transmitter, and the image of the document is scanned. Information is temporarily stored in one frame memory 2. Upon receiving the end signal from the input device 1, the control device 4 sends information on the track address to be recorded to the search control device 5, so that the recording/playback pink-up of the information recording/playback device 3 is moved to the destination address. . Thereafter, the information recording/reproducing device 3 is set to recording mode and the information in the frame memory 2 is recorded. Further, index information for searching information is recorded in an external storage device 7 composed of a floppy disk or the like.

However, when these are actually used, the following problems arise. First, to automatically search.

It is necessary to code all the keywords and register them in a file, which is extremely difficult work. Second, since the information recording medium and the medium on which the search index information is recorded are separate, they must be used as a pair, making storage and management troublesome. Especially when using a magnetic floppy to record index information, it is important to have a spare magnetic floppy because the information may be destroyed or erased for some reason during use. Is required. Furthermore, if you lose a magnetic floppy disk that has index information recorded on it, it will be very difficult to search for information about it.
