Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an information storage device that sequentially and intermittently sequentially outputs image axis information recorded on a plurality of recording media in the form of electrical signals for each valley recording medium. The present invention relates to a method for storing information in a predetermined format on a storage medium such as an optical disk.

This type of information storage device is used, for example, to store image information such as documents generated in large quantities in an easily searchable manner. Various types of information storage devices of this type have been developed and put into practical use, especially recently. However, there are still problems that need to be resolved in terms of ease of use.

The configuration of a conventional information storage device and its points will be briefly described below.

First, in the order in which it was input, that is, the m
There is a method in which captured image information is written to a disk, which is a storage medium, along with address information to distinguish it from other information. When storing a large number of documents in which FF14 numbers are recorded in advance in the order of their page numbers, there arises the inconvenience of having to manually arrange the documents in the order of their page numbers.

Next, if there is a single type of document, there is a method 5 that is configured to file files in order of page numbers without having to perform alignment in advance.

This frees you from the hassle of page alignment. However, as the number of document types increases, the inconvenience arises in that the 5C documents must be manually organized by type in advance. In addition, a large number of sentences t can be written to, for example, ADF
(automatic document feeding device) to perform reading, it is easy to cause an erroneous operation such as double feeding of documents with the same page number.

Furthermore, in conventional information storage devices, when modifying or correcting information, a separate area is reserved for each piece of information to store the modified content. In this case, it is necessary to secure a sufficiently large area for each piece of information for correction.
). Otherwise, corrections that involve significant additional corrections will not be possible due to a lack of storage space.

However, if a sufficiently large storage area for correction is secured for each piece of information, the amount of information that can be effectively stored will be significantly reduced. A problem arises in that the large storage area prepared for this is wasted.

This invention was made all at once to solve the above-mentioned complicated problems.The purpose of this invention is to solve the above-mentioned problems. It is possible to store data on a storage medium such as an optical disk without performing troublesome preliminary work such as aligning pages or sorting by type, and the storage state is
We provide an information storage device that allows for later retrieval [in a suitable format], and also enables efficient changes and corrections to each piece of information without creating wasted storage space. In order to achieve the above object, the present invention is structured.

Image information recorded on a plurality of recording media is electrically transmitted to each recording medium. c (Sukubushi in the form of W,
In an information storage device that stores this read information on a storage medium using a predetermined recording method, before storing the read information on the storage medium, the information is stored on the storage medium. First, read the identification information about the identifying code and the type specified by the code (the total number of pages of the recording medium on which the W report is recorded) from the recording medium. A storage area corresponding to the total number recognized by this means is set in the storage medium for each type of code, and the storage area set for each code is read from the storage medium. In addition, a correction information storage area is separately set to collectively store the correction contents of each of the valley information stored in the storage medium. If it becomes necessary to modify the information stored in
In step 5, all of the modified contents are stored in the above modified information storage area, and all address information of the area where the modified contents are stored is stored in the area where the one piece of information targeted for the modification is stored. is expressed as a percentage.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows the configuration of an information storage device according to an embodiment of the present invention. In the device shown in the figure, an original disk is used as an information storage medium.
Use 3. Further, the information recording medium is a single document 1 in which paper of a predetermined size and format is used.

The main parts of the device are a reading section 6, a page buffer memory 7, an image information extraction section 8, a character recognition section 9, an address memory 10,
It is composed of a control section 11, a write/read section 12, an output section 14, an operation keyboard 15, and the like. Sentence#
The reading of the information recorded in 1 is performed by the reading section 6. Also, writing and reading to and from the optical disc j3 are performed by the writing/reading section 12.
There are two types of buildings on the 1st floor. In the first type of document, 16 reports related to image information 2, information number 3, total number 4, and page number 5 are recorded. Information, that is, information regarding information 3, information number 3, and page number 5 is recorded in image 1.

Here, picture@information 2 is the answer that is the king of the document itself. Information number 3 corresponds to the code described above, and is identification information that specifies the type of document. The total negative number 4 means, when - type information is recorded across multiple documents, the total number of documents, that is, the total number of documents. The page number 5 is a serial number assigned to each document, and is numbered by 1 from the lowest number (1) to the highest number.

The document 1 is automatically read by the reading unit 6 by the ADF, for example.
supplied to

The reading unit 6 includes a light source that illuminates the document 1, a text that has been illuminated,
COD (
It consists of a photoelectric V converter such as a charge-coupled device) and an imaging optical system.

The page buffer memory 7 is a so-called RAM (a random access memo is used, and it stores one unit (one page of a document)).
Alternatively, it has a storage capacity sufficient to store all the image information of several units (several pages of documents).

The image information extractor 8 selects the image information of the designated address area in the page buffer memory 7 from the page buffer memory 7 and outputs it to the character recognition unit 9.

The character recognition section 9 recognizes the information number 3, the total number 4, and the page number 5 using well-known character recognition means.The address memory 10 stores address information on the optical disk 13.

The control section 11 centrally controls the operations of each section.

Furthermore, the controller section 11 also has a control function for making modifications such as changes and corrections to the image information for each information number. Specifically, the optical disc 1
A separate correction information storage area is set up to store all the correction contents of each image information stored in 3. At the same time, the need for correction to the stored image information arises. In this case, the correction Wk is stored in the above correction information storage area, and the address 1# of the area where the above pressure reduction content is stored is stored in the area where the f/r information that is the target of the correction is stored. It is designed to memorize information.

The write/read unit 12 includes a laser oscillator, an optical modulator that modulates the original beam according to the original beam VC input information from the laser oscillator during convolution, an optical head that scans the rotationally driven optical disk 13 in the radial direction, and It is made up of J and these control departments.

Furthermore, if a so-called semiconductor laser gold layer is used as the laser beam generation source, an optical modulator or the like will not be necessary, and the laser generation source can be integrated into the optical head, resulting in a significant reduction in the size of the honorary bladder protrusion 120. You will be able to measure.

The output unit 14 outputs the image information read from the original disc 13, and there are two output formats to choose from: recording output as a so-called hard copy or display output on a CRT display or the like.

The operation keyboard 15 is used, for example, to give commands to the device.Next, the configuration of the information storage device according to the embodiment of the present invention is as follows.
An example of its operation will be explained in more detail. First, the format of the optical disc 13 is shown in step 5 shown in FIG. 2nd writing area T2. 3rd writing area T3...
...The storage area is divided and set up in concentric circles. For example, the first writing area T1 contains the image information of the first page, the second writing area T2 contains the image information of the second page, and the third writing area T3 contains the image information of the third page. In each writing area TI, image information is written respectively.
T2. T3-... are each made to correspond to one unit of image information.

Here, let's talk about case 4, where multiple documents are stored in order of information side and page number, which are not classified by information type and are also in an irregular order. Among them, the document with the first negative number has the above-mentioned work 5 and information number 3. The total number of pages is 4°, the page number is 51, and the image information 2 is recorded in advance. In addition, at least the information number 31, page number 52, and image information 2 are recorded in advance in the documents from the second page onwards. The Joki Bunko is supplied to the reading unit 6 as ADFiC
At this point, only the first document, that is, the first negative document in this case, is supplied first, and the other documents are supplied to the reading unit 6 with their information side classification and page order completely irregular. Ru.

Here, for ease of understanding, as shown in Figure 3,
An example will be explained in which a total of 8 documents, with two different information numbers 3 and 5 pages and 3 pages, respectively, are stored on the optical disc in the order of information side and page number.

The above eight pages of text t# are in a state where both the information side and the page numbers are irregular. First, as shown in Figure 4 (a), the content of information number 3 is "A". The first negative document of the group is supplied to the reading section 6. The reading section 6 reads the entire document. The read image information is temporarily stored in the page backup memory 7. The information stored in this page buffer memory 7 includes information numbers 3. The total number of pages is 4. Page number 5, and one unit of image information 2 is included.

Among the information stored in the buffer memory 7Vc, information number 3. Information regarding the total negative number 49 page number 5 is output to the character recognition unit 9, where each content of the information number 3° and the total number 42 page number 5 is sequentially recognized.

Thereafter, the controller 2 section 11 selects f on the optical disk 13 based on the information number 3 recognized by the character recognition section 9.
Determine all address information in c. This address information is obtained by converting the information number 3ft using a predetermined addressing calculation formula. As a result, on the optical disk 13, a storage position, a so-called leading address, is designated at which to start storing the series of image information 2 corresponding to the above information (reference number 3).

Next, the controller unit 11 creates an area for storing the entire document (for all members) having the same information number, based on the all-member number 4 recognized by the character recognition unit 9. secure.

In other words, if there are n documents with a certain information number and the first address of this document is m, then from m to (m -1-
After the storage area up to n-1) is secured, the controller unit 11 stores the image information of the gun captured @2 based on the page number 5 recognized by the character recognition unit 9 and the above-mentioned start address. If page number 5 is the first page, specify the address position on the optical disk 13 to be stored.
The writing area for this image information is specified at the above-mentioned top address. Further, for the second page or later, the writing area for the read image information is specified at an address after the first address by the number of page numbers.

The address information on the optical disk 13 determined as described above is registered and declared to be stored in the address memory IO.

As described above, the write area on the optical disk 13 is secured by one size according to the number of participants, 4, for each information number 3, based on the results of the recitation section kesaba, and at the same time, Each start address is determined, and then individual addresses are specified for each negative number 5. Here, for example, the information number 3 recognized by the character recognition unit 9 is rAJ, and the total negative number 4 is "5". , if the negative number 5 is ``1'', then in order to ensure the capacity of 5 pages of memory,
In step 5 shown in FIG. 4(b), the 11th
1'-included area T1 is designated. At this time, if the first address is set to address 0 and 1, then 5 from addresses 0 to 4
One write area is reserved for information number rAJ.

As shown in Figure 5(a), the information number 3 is "B" on the arrow.
When the first page of the document is supplied to the reading unit 6, the reading unit 6 receives the image information 2 and the information subtitle 3. Number of all members 42 Read page number 5 and page buffer memory 7
send to After this, the above-mentioned three identification information 3. 4. 5 is extracted, and the content of each is recognized by the character recognition section 9Vc. Then, based on the recognition result, the controller fN1511 repeats the same operation as in the above case.In other words, in this case, the recognized information head number 3°, total number of pages 42 pages, acid number 5 are rBJ and rBJ, respectively.

Since it is "1", the first address is set to address 5,
Three write areas from here to address 7 are secured.

Then, the second IN report number rBJ that will be read after this
The image information on and after the page is stored at an address (6th address or 7th address) corresponding to the page after the above-mentioned first address.

Note that the position of the writing area on the optical disk 13 is the fifth
As shown in Figure (b), the fifth write area T5 and subsequent areas are allocated. The image information with information number rBJ is written from the fifth writing area T5. Even if the above 15 is not classified as information or the page order is irregular, the first negative After the documents are read, they are automatically classified according to VC information and page alignment is performed, so that the documents are recorded neatly on the optical disk 13.

Next, the original disk 1 on which recording was performed as described above.
The case where image tit information is generated from 3 will be explained.

For example, if you want to output the information one after another in order of information number and page number, input the information number and all commands to that effect from the keyboard 15. As a result, the controller unit 11 issues a command to the write/read unit 12. The write/read unit 12 starts reading from the beginning of the write area on the optical disk 13 in which the image information of the information number is stored. The image information that is successively displayed is temporarily stored in the page buffer memory 7 via the controller section 11. Then, the page buffer memory 7 outputs it as a hard copy or an image display via the output section 14f.

Further, when extracting and outputting only a specific page number from a specific information number, the information number and page number are input using the keyboard 15, for example. In response to this, the controller unit 11 outputs the address information corresponding to the input information number and page number from the address memory 10, and issues a control command to read out the image information corresponding to the address 1H information sent out. is given to the write/read unit 12.

Furthermore, if the +tV information stored in the optical disk 13 is to be modified or corrected in step 5 described above, in this embodiment, the modification process is performed in step 5.

That is, the modification information is read by the reading section 6.

Along with this, the information number 3゜ all negative numbers 4 for the original information that was the target of correction from among the @ that was read.
Ei Taniuchi, number 5 on page 2, is recognized by the character recognition section 9. Thereafter, the modification information is addressed and stored in a predetermined area of the optical disc 13. The address is stored in address memory 10. Thereafter, as shown in FIG. 6, the address is a blank area 20aK in the image information storage area 20, which is a part of the area reserved in advance to store the information to be corrected. %
be included.

This margin area 20a only needs to be able to store all of the address information, so it does not need to be very thick, and there is no worry that the storage area for the original image information will run out. In this way, modifications such as changes and corrections can be made efficiently without losing much of the effective storage area for storing image information. By reading out the area specified by the specified address, corrected image information will be output.

As described above, even when handling a large number of different types of documents, the information storage device according to the present invention does not require troublesome preliminary work such as sorting the information recorded in these documents or sorting them by type. It can be stored on a storage medium such as an optical disk without having to perform any additional steps, and the storage state can be in a format suitable for later retrieval.Furthermore, changes and corrections to each information are unnecessary. This can be done efficiently so that a large storage area is not required.
