Abstract

There is a composite image filing system in which optical discs and microfilms are organically combined and integrally managed. This system comprises optical discs and microfilms in which image files are recorded and a work station to register, search, and process the image files. The work station has a memory to store search information of a format integrated between the optical disc and the microfilm. The search information which specifies the image files includes information indicative of the kind of medium (microfilm and optical disc), information to specify the medium number of the optical disc and the physical address in the optical disc in the case of a optical disc file or to specify the cartridge number and frame number in the case of a microfilm file, and the file name. The work station manages the image files by the search information and controls the optical disc so as to back up the search information corresponding to the image files recorded in the optical discs. Since the search information of the image files is stored into a backup dedicated memory such as optical disc or floppy disc nearest to the operation unit, the security of the search information is assured and the search information can be easily managed and reconstructed from the backup dedicated memory.

Claims

1. A filing system comprising:

first random access file means for recording image information;

second file means for recording image information, said first random access file means being larger in capacity than said second file means; and

memory means for storing a plurality of pieces of search information each used for searching said first and/or second file means for corresponding image information;

each piece of the search information including identification information identifying said first and/or second file means which stores the corresponding image information,

wherein at least one of the plurality of pieces of search information stored in said memory means are sent to and stored in said first file means if its identification information identifies said first file means, and at least one of the plurality of pieces of search information stored in said memory means are sent to and stored in an external storage means if its identification information identifies said second file means.

2. A filing system according to claim 1, wherein said first random access file means utilizes an optical disc and said second file means utilizes a microfilm.

3. A filing system according to claim 1, wherein the search information relating to image information is stored in said first random access file means when the image information is recorded in said first random access file means.

4. A filing system comprising:

one or more first random access file means which can record image information;

a plurality of second file means which can record image information, said first random access file means being larger in capacity than said second file means;

editing means for synthesizing the image information read from said first random access file means and the image information read from said second file means with each other,

wherein said editing means further comprises means in which search information to integrally manage said image information recorded in said first random access and second file means is stored, wherein the search information comprises identification information for indicating in which one of the first random access file means and the second file means the image information is stored, position information for indicating a position at which the image information is stored in a format corresponding to the identification information, and keyword information for searching the image information;

search means for comparing information input by input means with the search information and for searching information for outputting image information;

writing means for writing the search information in said first random access file means if the identification information indicates said first random access file means;

control means for writing the search information in an external memory if the identification information indicates said second file means; and

reading means for reading the search information from said first random access file means and/or from said external memory, and for storing the read search information in said editing means, wherein said reading means reads the search information as required from said first random access file means and/or from said external memory.

5. A filing system according to claim 4, wherein said first file means utilizes an optical disc and said second file means utilizes a microfilm.

6. A filing system according to claim 4, wherein said editing means is a work station having display means, data input means, and a buffer to store image date.

7. A filing system according to claim 4, wherein said writing means writes the search information relating to image information in said first random access file means when the image information is recorded in said first random access file means.

8. A filing system according to claim 4, wherein said reading means reads a specific piece of the search information from said first random access file means and/or from said external memory.

9. A filing system according to claim 4, wherein said writing means writes the search information for said one or more first random access file means in one of said one or more of first random access file means.

10. A filing method comprising the steps of:

providing image information in one or more first random access file means which can record image information;

providing image information in a plurality of second file means which can record image information, the first random access file means being larger in capacity than the second file means;

synthesizing image information read from the first random access file means and image information read from the second file means with each other, using an editing means,

wherein the image information recorded in the first random access and second file means is integrally managed using search information stored in a memory in the editing means, wherein the search information comprises identification information for indicating in which one of the first random access file means and the second file means the image information is stored, position information for indicating a position at which the image information is stored in a format corresponding to the identification information, and keyword information for searching the image information;

comparing information input by input means with search information from a search means and for searching information for outputting image information;

storing the search information in the first random access file means if the identification information indicates the first random access file means;

storing the search information in an external memory if the identification information indicates the second file means; and

reading the search information from the first random access file means and/or from the external memory, and storing the read search information in the editing means, wherein said reading step reads the search information as required from the first random access file means and/or from the external memory.

11. A filing method according to claim 10, wherein the first file means utilize an optical disc and the second file means utilize a microfilm.

12. A filing method according to claim 10, wherein said synthesizing step is performed using a work station having display means, data input means, and a buffer to store image date.

13. A filing method according to claim 10, wherein said storing step stores the search information relating to image information in said first random access file means when the image information is recorded in said first random access file means.

14. A filing method according to claim 10, wherein said reading step reads a specific piece of the search information from said first random access file means and/or from said external memory.

15. A filing method according to claim 10, wherein said storing step stores the search information for said one or more first random access file means in one of said one or more random access file means.
