Abstract

PURPOSE:To reduce the copying time by recording an optical disk number of management information of an old optical disk and address information of picture information onto a new optical disk so as to allow picture information belonging to plural management information to have only to be copied once. CONSTITUTION:With an optical disk number coincident with an old optical disk 16a as the result of reading management information of a new optical disk 17a, the address information is stored in a storage device 2, the management information of a document to be copied from the disk 16a is read, and the address information is stored in the device 2. When the address information of the document to be copied is the same as the preceding address information, the recording address information of the disk 17a corresponding thereto is stored in the device 2 and the picture information of the disk 16a corresponding to the information is not read and recorded on the disk 17a. When the picture information belongs to plural management information in the disk 16a in this way, the information is copied only once onto the disk 17a and not copied for twice or over.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention Industrial Application Field The present invention uses a so-called image information storage and retrieval device that records image information such as documents and drawings on an optical disk and searches this information. The present invention relates to a copying method in an image information storage and retrieval device for copying (duplicating) all or part of the information on the optical disc to another optical disc.

2. Description of the Related Art In general, this type of image information storage and retrieval device reads image information of documents, drawings, etc. (hereinafter simply referred to as documents) by optical two-dimensional scanning and sequentially records them on an optical disk. Management information such as the recording address of the image information and keywords for searching is also recorded at the same time.

Here, the management information is composed of a management set (document) of a plurality of image information, and is recorded in an area separate from the image information.

When reading image information, it is searched by inputting a keyword of the management information and reproduced on a display device, printer, etc.

Based on an already recorded document, change or add part of its image information or management information to create a new collection (
When recording image information as a document (document), for image information that has not changed, only the address information is recorded as the management information of the new document to avoid the waste of recording the same image information twice. There is.

To copy all or part of a document recorded on an optical disc to another optical disc.

At least two optical disk devices each having a function of reading and recording information on an optical disk are connected to an image information recording and retrieval device.

The conventional copying method first reads the management information of all the documents to be copied from the optical disc to be copied (hereinafter referred to as the optical disc), stores the address information of this management information in a memory device, and According to this address information, the image information is read out and stored in the respective page memory devices. Next, the image information stored in the page memory device is recorded on the optical disk to be copied (hereinafter referred to as a new optical disk), and the recording address information is stored in the memory device.

By repeating this nine times, all image information is recorded, and finally all management information is recorded.

Problems to be Solved by the Invention However, according to this configuration, when recording image information in a plurality of sectors of a new optical disc, if there is a bad sector on the recording medium of the new optical disc, the bad sector is skipped and recorded. Therefore, since the start address and end address of the image information depend on the recording medium, the information on the Idemitsu disk (image information and management information) is stored in the physical address (as with normal magnetic disks, tracks and sectors). It becomes impossible to copy units (called). Therefore, at present, copying of optical discs is.

The information is read out page by page and recorded page by page.

Also, when you change or add a part of the image information or management information keywords based on an already recorded document and record it as a new document (normal page editing processing or change of search information) processing) involves recording the same image information more than once by storing only the recording address information of the new optical disc in the memory device as part of the management information of the new document for image information that has not changed. Eliminates waste. Therefore, a certain piece of image information may belong to multiple documents. In this case, there is a problem in that the image information is read and recorded multiple times when copying.

Yet again. Because the memory of the memory device that stores the recorded address information of the Shinko Demesque is erased when the power is turned off, and because its capacity is limited, a portion of the document recorded on the Idemitsu disk can be copied and stored again at a later date. When copying the remaining portion, there is also the problem that if a certain piece of image information belongs to multiple documents, the image information may be copied again even though it has already been copied.

The present invention has been made in view of the above-mentioned problems, and when one image information belongs to multiple documents,
To provide a copying method in an image information storage and retrieval device which prevents the image information from being copied again when the image information has already been copied to a new optical disc.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention reads management information from a new optical disc, and sets the optical disc number in the management information to the optical disc number in the management information of the original disc. If the address information is the same as that of the document to be copied, the address information is stored in the storage device, then the management information of the document to be copied is read from the source disk, the address information is stored in the storage device, and then the document to be copied (the document to be copied is It sequentially checks whether the address information of the disc) is not the same as the previous address information, and if it is not the same, reads the image information of the original disc based on the address information and transfers it to the new optical disc. and storing the recording address information of the image information recorded on the new optical disc in the storage device, and if the address information is the same, reading the image information of the original disc corresponding to the address information and transferring it to the new optical disc. The recording address information of the image information of the new optical disc is simply stored in the storage device without performing any recording.

Operation According to the present invention, the management information of the new optical disc is first read by the above-described configuration, and if the optical disc number therein is the same as the optical disc number of the original disc, the address information is stored in the storage device. Ru.

Next, the management information of the document to be copied is read from the source disk, and its address information is stored in the storage device. If the address information of the document to be copied at that time is not the same as the previous address information, the image information on the original disk is read based on that address information.
Recorded on a new optical disc. At the same time, the recording address information of the new optical disc is stored in the storage device.

If the address information of the document to be copied (the original disc) is the same as the previous address information, the recording address information of the image information of the new optical disc corresponding to it is simply stored in the storage device, and the address Image information corresponding to the information on the original disc is not read out or recorded on the new optical disc.

In other words, if one image information belongs to multiple management information (documents) on the old optical disc, that image information belongs to one
The data is copied to the new optical disc only once, and is not copied more than once (again) as in the past.

The operation of the method of the present invention will be described below with reference to the flowchart shown in FIG.

First, in step (hereinafter referred to as ST) 1, it is determined whether a document has already been recorded on the new optical disc 17a set in the second optical disc device (B) 17. If no document is recorded, there is no need to create address management table X, and the process advances to ST8. If the document is recorded, proceed to ST2.

In ST2, a counter for counting the document number n of the counter section 3 is set to "1", and in the subsequent ST3, the management information of the document number n (=1) of the new optical disc 17a is read.

Next, at 8T4, it is determined whether or not the edge disk number of the copy information in the management information is the same as the optical disk number of the light output disk 16a set in the first optical disk device (A)ls. However, if they are not the same (
If Nα in ST4), proceed to ST5, and if the same case (Nα), proceed to ST5.
If YES in ST4), in ST5, the document number 42 and page number in the copy information area 40 are set in the label section area 47 of the address management table information(
The old address information) 43 is set in the old address information area 48, and the address information (new address information) of each page in the management information is set in the new address information area 50.

Thereafter, the address management table X is created by repeating steps ST3 to ST7 in the same manner until the copy information of the final document on the new optical disc 17a is set.

Once the final document copy information is set, the process advances to ST8.

In ST8, the copy start document number of the light output disc 16a is set in a counter for counting the document number n. Typically, the copy start document number and end document number are designated by the operator. Continuation <In ST9, the optical disc 16 set in the first optical disc device (A) 16
Read the management information of document number n of a, set the address information of the document white image information area to the document white image information area 53 of the address management table Y, and set the address information (old address information) of each page to the address management table Y. The old address information 54 is set.

Thereafter, in the same manner, ST9 to ST11 are repeated until the old address information of the copied document is set, and the old address section 53. Create 54 tables.

8T when the old address information of the copied document is set.
Proceed to step 12.

At 8T 12, the counter that counts the record number n of the address management table Y is set to "1", and the process continues.
In 5T13, it is determined whether the old address information of this record number n is within the range of the document white image information area, that is, the address information (old address information) of the document to be copied (the light output disk 16a') is the same as the previous address information. Check if they are not the same.

If within the range (if not the same) (YES in 8T13)
), the old address information is stored in the address management table Y
Although it is not included in the document white image information area of other documents, there is a possibility that it is included in the document white image information area of the already copied document in the address management table X, so the process advances to ST19.

If it is outside the range (if they are the same) (NO in ST13)
, the old address information is included in the document white image information area of another document (document before this document number) in the address management table Y, and the image information corresponding to the old address information has already been recorded on the new optical disc 17a. 8T 14 as there is a possibility that the

In 5T14, record number m of address management table Y
, set the current record number n minus 1 to the other counter that counts , and continue (ST15.5T
By repeating 16.5T17, υ, record number n
Address information that matches the old address information of is searched from among the old address information of previous record number m.

Find it (YES in ST15) and proceed to ST18.
The new address information of record number m of table Y corresponding to the old address information is recorded in the new address information area 56 of record number n of table Y, and the image information recording flag of flag area 57 is turned OFF.

If it cannot be found (YES in ST15), ST
Proceed to step 19.

At 8T 19, another counter that counts the record number m of the address management table X is set to "1", and by repeating ST20. Search for address information from the old address information of record number m in table X. Search (ST 20
YES) and proceed to ST 23, record the new address information of record number m of table Turn off the recording flag. If it cannot be found (Y in ST21)
ES) proceeds to ST24.

In ST24, the image information of the light output disc 16a is read based on the old address information of the record number n of the table Y and stored in the page memory device 14.

Next, in 5T25, the image information stored in the page memory device 14 is recorded on the new optical disc 17a set in the new optical disc device (B) 17, and the recorded address information is stored in the record number n of the address management table Y. The image information is recorded in the new address information area 56, and the image information recording flag (flag area 57) indicating that the image information has been recorded on the new optical disc 17a is turned ON.

Thereafter, in the same manner, steps 5T13 to 5T27 are repeated until the new address information of the last record number of table Y is stored in the new address information area 56 of address management table Y, and a table of new address sections 56 and 57 is created. do.

In this way, when the creation of the address management table Y in which the old address information of all the optical discs 16a and the new address information of the new optical disc 17a is completed, the ST
Proceed from ST 26 to ST 28.

In addition, as described above, the address management table is
By creating Y, the address of the so-called image information of the old optical disc 16a, which occurs due to a bad sector of the optical disc, or which occurs when copying only a part of the document recorded on the old optical disc 16a. It is possible to prevent the phenomenon of inconsistency between the information and that of the new optical disc 17a, and also when the same image information (a piece of image information) in the mouth disc 16a is under the management of multiple management information (documents). There is an advantage that the image information only needs to be recorded once on the new optical disc 17a.

8T2B sets the counter "1" to count the record number n of the address management table Y, and continues (ST
At step 29, the management information of the document number in the record number field of table Y is read from the new optical disc 16a.

At this time, the address information of the image information in the management information is converted to new address information by referring to the address management table Y, and the address information of the document self-portrait information area 53 is converted to the new address information of the image information recording flag of the flag area 57. The address information is converted into the first start address information and the last end address information in the corresponding document, the document number is converted to the latest document number of the new optical disc 17a, copy information is created, and this is stored in the copy information area 28. Add record to .40, 5
Proceed to T30.

In 5T30, this management information is recorded on the new optical disc 17H.

Thereafter, in the same manner, steps 8T29 to 5T33 are repeated until the management information of the document number of the last record of the address management table Y is recorded on the new optical disc 17a.

In this way, when the management information of the document number of the last record of the address management table Y has been recorded on the new optical disc 17a, the information about all or part of the documents on the mouth disc 16a is copied to the new optical disc 17H. That will happen.

Effects of the Invention As is clear from the detailed description above, the present invention provides a new optical disc that records at least the optical disc number and the address information of the image information among the management information of the disc. In this system, when one image information belongs to multiple management information (documents), that image information is copied to the new optical disc only once, so it is recorded on the original disc from which it is copied. Even when copying all the document information that has been copied, or when copying part of the document information multiple times, and even when copying the same image information in multiple documents in the source disc to be copied. Even if the image information is under the control of a new optical disc, the image information only needs to be copied once to the new optical disc to be copied.Therefore, there is no wastage of area for recording image information, and the copying time can be shortened. There is an effect.
