Next, an example of the operation of the copying apparatus of the present invention will be described.

] 8 First, document registration and abstract creation will be explained with reference to the flowchart shown in FIG. A plurality of sheets (N sheets) of originals are set on the scanner 41, and an optical disk 233 is set on the optical disk device 51, respectively.

At this time, CPUl0 detects the attachment of the optical disk 233, accesses the optical disk 233, and
Volume number, number of registered files, as registration status of
The unregistered space capacity and the like are displayed on the display panel I2.

On the other hand, if the optical disc 233 is a new optical disc 233 with no document information registered, initialization processing is performed. In the initialization process, the optical disk 23 is
3, issues a volume number, and registers it in the search information area of the optical disc 233. Note that at this time, a user registration number other than the volume number is also registered using the keyboard J1.

When the user confirms that the document can be registered through the message on the display panel 12, the user presses a reading start button (not shown) on the keyboard 11, and the document information on the first page is transferred to the scanner 41. The image is converted into a signal, subjected to various image processing such as filtering processing and gradation processing, and then temporarily stored in the page memory 30 (herein referred to as page A) via the image bus 7. Subsequently, the image data stored above is stored in -dan C0DEC21.
After the amount of data is compressed, the data is stored on the optical disc 233 via the optical disc device 51. At the same time, under the control of the basic system section 1, a four-digit file number is assigned to each document according to the order in which the document information is registered on the optical disc 233. The file number issued here is registered in the search information area of the optical disk 233 as search information within the optical disk 233.

On the other hand, the image data stored in the page memory 30 includes
Image data of a barcode and number string as search information consisting of the volume number, file number, etc. is added. The document information of the first page to which the barcode and the image data of the number string have been added is printed out as the cover of the abstract by the printer 43 via the image bus 7 and the printer interface 42.

Next, scan the scanner 41 in the same way as for the document information on the second page.
is converted into an electrical signal and temporarily stored in the page memory 30 via the image bus 7. Further, the stored image data is compressed by the C0DEC 21 and then passed through the optical disk device 51 to the optical disk.
It is accumulated in 33. On the other hand, the image data stored in the page memory 30 is subjected to a reduction process of 1/4 (area ratio: 1./1.8). Various processing methods are possible, but
Here, the image data is compressed by simple thinning processing. The image data compressed to 1/16 is temporarily stored in a specific page memory 30 (herein referred to as page 8) allocated for the back side of the abstract.

The above processing is performed up to the final page (page N). Furthermore, similar to the first page, search information using a barcode and a number string is added as key information at the time of search.

As described above, the document information on the back side of the abstract to which the search information has been added is already recorded on the front side by the printer 43 via the image bus 7 and the printer interface 42, and is printed out on the back side of the abstract. Images of the image information of this abstract are shown in FIGS. 3(a) and 3(b). Third
FIG. 3(a) shows an example of the front side, and FIG. 3(b) shows an example of the back side. As shown in the figure, for documents of 18 pages or more, the last page is recorded in the reduced page area at the bottom right.

As described above, the original information is stored on the optical disc as image data.
33, and records the document information of the first page on the front side and the reduced document that represents the entire document information on the back side.

Next, document search and copying will be explained based on the flowchart shown in FIG. First, put the abstract on the scanner 41,
Then, the optical disks 233 are respectively set in the optical disk device 51. At this time, CPU10 detects the attachment of the optical disk 233 using the same control as when registering the document, accesses the optical disk 233, and records the registration status of the optical disk 233 such as the volume number, number of registered files, file number, unregistered space capacity, etc. Displayed on the display panel 12.

This makes it possible to confirm to some extent whether the document information corresponding to the abstract is registered on the optical disc 233. Also, at this time, various search modes such as copy pages can be set using the keyboard 11.

Then, document search is performed by the display on the display panel 12.
After confirming that copying is possible, press the copy button (not shown) on the keyboard 11 to read the barcode BCDI (BCD2) recorded in the abstract with the scanner 41, and CPU10 reads the barcode BCDI.
Search information is detected from (BCD2). This detected search information is compared with the search information on the optical disc 233. That is, first, it is checked whether the volume number registered in the search information area of the optical disc 233 and the volume number obtained from the abstract match, and if they match, then the file number obtained from the abstract is matched. A search is performed to check whether the object is registered in the search information area of the optical disc 233 or not.

As a result, if there is a matching file number, image data is read page by page from the image data area 3 corresponding to the file number. Optical disk device 5
The image data read from 1 is -, lE! , C0D
After the data is expanded by the EC 21, it is temporarily stored in the page memory 30 via the image bus 7. The image data stored in the page memory 30 is sent to the printer 43 via the image bus 7 and the printer interface 42.
Printed out page by page. 2. Print out up to the last page.

On the other hand, if the volume number of the optical disc 233 installed is different from the volume number obtained from the abstract,
The document search is stopped and a message such as "Volume number is incorrect" is displayed on the display panel 12. In addition, if the volume numbers match but other contents such as file numbers do not match, the display panel 12 will display "No matching document".
Display a message such as Cancel the original document search.

As described above, the original manuscript information can be easily and immediately obtained from the paper on which the abstract information is recorded. Furthermore, by adding a volume number to the search information, multiple optical discs can be managed in an integrated manner, erroneous searches can be prevented, and document searches become easier.

As mentioned above, image information is converted into digital data and read with a scanner, this read digital data is stored on an optical disk, abstract information of the digital data stored on this optical disk is recorded, and information on this abstract information is recorded. The search information indicated by the barcode is added to the copy sheet (=1).

This simultaneously satisfies the advantages of the immediacy of information access of a paper file and the large storage capacity of an electronic file.In other words, it is possible to simultaneously satisfy the advantages of the immediacy of information access of a paper file and the large storage capacity of an electronic file. By replacing image information stored on an optical disk with image information stored on an optical disk, it is possible to easily register and search document image information, and to significantly reduce document space. Since this is done on paper, it is possible to avoid compromising information access speed, which is an advantage of paper files.

5 In addition, by configuring the search information with a polynumerical number that distinguishes optical discs and a file number that distinguishes document information on optical discs, it is possible to prevent erroneous searches among multiple optical discs. It also becomes easier. Sunai Tsuji,
Misidentification of document information on individual optical disks can be prevented in the case of a plurality of optical disks. Therefore, a plurality of optical discs can be managed in an integrated manner, and document information can be searched for each item.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an image forming storage device that can easily and easily register and search images at a low cost.
