Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention records all image information of the optical disc by using a so-called image information storage / retrieval device for recording image information such as a document or drawing on the optical disc and searching for it. Alternatively, the present invention relates to a copy method in an image information storage / retrieval device that copies (copies) a part of the image to another optical disc.

2. Description of the Related Art Generally, this type of image information storage / retrieval apparatus reads image information of a document or drawing (hereinafter simply referred to as a document) by optical two-dimensional scanning and sequentially records the image information on an optical disc. Management information such as a recording address of information and a keyword for retrieval is also recorded at the same time.

Here, the management information is composed of a plurality of management units (documents) for management of a plurality of image information, and is recorded in an area different from the image information.

When the image information is read out, the keyword of the management information is input to perform a search, and the information is reproduced on a display device, a printer or the like, and this is performed.

When a part of the image information or management information is changed / added based on the document already recorded and is recorded as a new collection (document), the address information for the unchanged image information Only this is recorded as the management information of a new document, thus eliminating the waste of recording the same image information twice.

In order to copy all or part of a document recorded on an optical disc to another optical disc, at least two optical disc devices having a function of reading and recording information on the optical disc are connected to the image information recording / retrieving device. To do.

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

However, according to such a configuration, when image information is recorded in a plurality of sectors of a new optical disc, if there is a defective sector on the recording medium of the new optical disc, the defective sector is skipped and recorded. Therefore, since the start address and end address of the image information depend on the recording medium, the information (image information and management information) of the old optical disk is called a physical address (usually a track or a sector like a magnetic disk). ) It becomes impossible to copy in units. Therefore, at present, the copy of the optical disc is read in page units and recorded in page units.

In addition, when you change or add a part of the keyword of image information or management information based on an already recorded document and record it as a new document (ordinary page editing process or change of search information) The same image information is recorded twice or more by storing only the recording address information of the new optical disk in the memory device as a part of the management information of the new document for the image information which is not changed. To reduce the waste of. Therefore, a certain image information may belong to a plurality of documents. In that case, when copying is performed, the image information is read and recorded a plurality of times.

Furthermore, since the contents of the memory of the memory device for storing the recording address information of the new optical disk are erased when the power is turned off and the capacity is limited, a part of the document recorded on the old optical disk is copied. There is also a problem in that, when a certain portion of image information belongs to a plurality of documents when the remaining portion is copied again later, the image information is copied again although it has already been copied.

The present invention has been made in view of the above problems, and when one image information belongs to a plurality of documents,
It is an object of the present invention to provide a copy method in an image information storage / 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 problems described above, the present invention reads management information from a new optical disk, and the optical disk number of the management information is the same as the optical disk number of the management information of the old optical disk. In that case, the address information is stored in the storage device, then the management information of the document to be copied is read from the old optical disc, the address information is stored in the storage device, and then the document to be copied (old optical disc). Whether the address information of the old optical disc is the same as the previous address information or not, and if it is not the same, the image information of the old optical disc is read based on the address information and is recorded on the new optical disc. If the recording address information of the image information recorded on the new optical disc is stored in the storage device and is the same, Does not read the image information of the old optical disk corresponding to the address information and records it on the new optical disk, but only stores the recording address information of the image information of the new optical disk in the storage device. .

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

Next, the management information of the document to be copied from the old optical disk is read and the address information is stored in the storage device. At that time, if the address information of the document to be copied is not the same as the previous address information, the image information of the old optical disc is read based on the 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.

On the other hand, if the address information of the document to be copied (old optical disc) is the same as the previous address information, the corresponding recording address information of the image information of the new optical disc is simply stored in the storage device. The image information of the corresponding old optical disk is not read and the new optical disk is not recorded.

That is, when one piece of image information belongs to a plurality of management information (documents) in the old optical disc, the image information is 1
Only once, the new optical disk is copied, and never twice (or again) as in the conventional case.

The new address information of the record number m of the table X corresponding to the old address information is set to the record number n of the table Y.
The new address information area 56 is recorded, and the image information recording flag in the flag area 57 is turned off. If not found (YES in ST21), proceed to ST24.

In ST24, the image information of the old optical disk 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 ST25, 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 recording address information is recorded in the address management table Y.
Recorded in the new address information area 56 of record number n of
The image information recording flag (flag area 57) indicating that the image information has been recorded on the new optical disk 17a is turned on.

In the same manner, ST13 to ST27 are repeated until the new address information of the last record number of the table Y is stored in the new address information area 56 of the address management table Y, and the tables of the new address parts 56 and 57 are created.

In this way, when the creation of the address management table Y in which the old address information of all the old optical disks 16a and the new address information of the new optical disk 17a correspond is completed, ST26 to ST
Proceed to 28.

As described above, the address management table is set to X, Y.
The address information of the so-called old optical disc 16a, which is caused by the defective sector of the optical disc or is generated when copying only a part of the document recorded on the old optical disc 16a. And the new optical disc 17a can be prevented from mismatching phenomenon, and the same image information (that is,
When a certain image information) belongs to the management of a plurality of management information (documents), the image information is recorded only once on a new optical disc.
It has the advantage that it only needs to be recorded in 17a.

In ST28, a counter "1" for counting the record number n of the address management table Y is set, and in the subsequent ST29, the management information of the document number of the record number n of the 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 into new address information by referring to the address management table Y, and the address information in the in-document image information area 53 is set to the image information recording flag in the flag area 57. The new address information is converted into the first start address information and the last end address information in the relevant document, and the document number is changed to the new optical disc 17a.
Of the latest document number, copy information is created, this is additionally recorded in the copy information areas 28 and 40, and the process proceeds to ST30.

In ST30, this management information is recorded on the new optical disc 17a.

Thereafter, similarly, ST29 to ST33 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 is completely recorded on the new optical disc 17a, the information about all or some of the documents on the old optical disc 16a is copied to the new optical disc 17a. It will be.

EFFECTS OF THE INVENTION As is clear from the above detailed description, according to the present invention, by recording at least the optical disc number and the address information of the image information in the management information of the old optical disc in the new optical disc, When one piece of image information belongs to a plurality of management information (documents), the image information is copied to the new optical disc only once. Therefore, it is recorded on the old optical disc to be copied. Even when all the document information is copied or when the document information is copied a plurality of times one by one, the same image information is managed under the control of a plurality of documents in the original optical disc to be copied. Even if the image information belongs to, the image information needs to be copied only once to the new optical disc to be copied. There is an advantage that the recording area is not wasted and the copy time can be shortened.
