Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a composite image file system consisting of, for example, a microfilm file and an optical disc file.

[Prior Art] Conventionally, a microfilm system has been used as a system for managing and utilizing an extremely large amount of non-code information (image information). Microfilm is excellent in terms of economy, storage stability, resolution, etc., and has the advantage of being able to make large numbers of copies at high speed, making it ideal for efficiently storing and managing file information that increases every year. Are suitable.

However, on the other hand, office automation has progressed rapidly in recent years, and there is a growing tendency for computers to be introduced into office equipment and for devices to be interconnected through communication circuits. In order to respond to this trend of computerization and communication, it is desirable that the information handled be stored in the form of electrical signals as much as possible, and electronic file systems have been attracting attention in recent years. Because electronic file systems store information in the form of electrical signals, they have features that microfilm systems do not have, such as high-speed retrieval and high-speed transmission. On the other hand, electronic file systems also diminish some of the advantages of traditional microfilm systems.

The disadvantages are that when manually converting information, there is no way to convert images in one shot through a lens system like in a microfilm system, and the conversion is performed by raster scanning one by one, which slows down large cassettes. Copying cannot be done quickly and economically; jG has no track record of long-term storage stability compared to microfilm, which has a long-term storage stability of 100 years! daytime, and the fact that microfilm is not recognized as legal evidence.

An even bigger problem is that when an electronic file system is introduced, the databases and information that were built up using the conventional microfilm system can no longer be utilized.

As already mentioned, both microfilm and electronic file systems have their advantages. In view of the recent trend toward office automation, electronic file systems have many advantages, but it is clear that microfilm systems cannot be ignored. Therefore, the user has to choose between two systems =-
Or, you will have to run and use two systems at the same time, which is a huge inconvenience.

[Problems to be Solved by the Invention] Therefore, a composite image file system combining a microfilm system and an optical disk file system is being developed. A file system that combines such different types of recording media is not just a combination, but an organic combination is desired. The present invention has been made in view of the above points, and its purpose is to propose a composite image file system that combines microfilm and a plurality of optical disks and can perform unified file management.

The HO2 plays an important role in storing search information for file searches. Namely, the HO2 stores search information for the optical disk file 40 and microfilm file 50 as will be described later, and stores the search information in response to requests from the wsto. The HO2 for updating, etc. may be replaced by a hard disk, for example, a magnetic bubble memory, a wire memory, or a battery-backed CMOS memory, or any other device as long as it is non-volatile and relatively fast. Further, the FPD 3 is a storage location for backing up search information for microfilm files. Of course, the FPD 3 is also used to read a program (IPL) for starting etc. for the WS 10.

(HD 2 memory map) FIG. 4(a) is a hard disk memory map.

Its contents are a program area and a search information record storage area. FIG. 4(b) shows the format of the search information record stored in the HD 2. The HD 2 contains images stored in the optical disk file 40 as described above, and images of each frame of the microfilm in the microfilm file 50. Search information corresponding to is stored together (see FIG. 5). It should be noted that the search information for different media, optical disk file 40 and microfilm file 50, has a common format as shown in FIG. 4(b). By having a common format, management of search information on different recording media becomes efficient and easy. However, from the viewpoint of uniformly managing image files, it is not necessary to insist on having a common format, and what is important is π, which can distinguish between recording media.

As shown in Figure 0, which explains the format of the search information record in Figure 4(b), this format is divided into six fields. An identification mark (DEV-ID) indicating whether the image corresponding to this search information record exists in the optical disk file 40 or the microfilm file 50 is set in the field 61. In this example, the microfilm image is “1°°” and the optical disc image is “1°°”.
Address information ADD of the medium on which the image corresponding to this search information record is recorded is set in the field 62. If it is an optical disc, this ADD is the drive number of the optical disc, and the address information ADD of the medium on which the image corresponding to this search information record is recorded. It includes the absolute address, etc., and if it is a microfilm, the cartridge number and frame number of the microfilm file are stored.

In the field 63, the size of the image corresponding to this search information record (P-5IZ) is set. This indicates, for example, whether the output image is A4/A3, etc. In the field 64, resolution information P-RES of the image corresponding to this search information record is set. In this example, the resolution is 400/300/2 at the time of input (registration).
Specify either 00dpi. The field 65 contains various other 13Sl related information OD such as compression ratio and positive/negative discrimination information regarding the image corresponding to this search information record.
D is set as necessary. In field 66,
Keyword information (KW) of the image file corresponding to this search information record is set. KW is a number, a letter,
It may be written in any symbol.

When the operator stores a desired image in the optical disk file 40, these search information records are input using the KBD 6 of the workstation 10 in correspondence with this image, and are written to the HO2. In addition, if you have a subcontractor record a large amount of images on optical disks or microfilm, have the subcontractor write the search data to a floppy disk using a computer, etc. in accordance with the specified format, and The search data on the disk is transferred and stored in the HO2 from the FPD3.

<Relationship of search information between each storage medium> The search information record for each image stored in the optical disk file 40 and the microfilm file 50 is the fifth one.
As shown in the figure, in the 0 diagram mixed and stored in HO2 according to the format shown in FIG. 4(b), "M" indicates microfilm and "00" indicates optical disk file. FIG. 5 illustrates a method for backing up search information records on the HDZ. That is, the backup of the search information and code of the microfilm is stored in the FPD 3, and the backup of the search information record of the optical disk file 40 is stored in the optical disk drive. Furthermore, the fifth
Apart from the individual backup method for each recording medium shown in the figure, an embodiment of a backup method for backing up all of HO2Kita's search information records in a backup-only optical disk will also be disclosed (described below in Figure 17). .

Below, the order of explanation of the embodiments is as follows: First, the l531 or MS51
, an explanation of the operation for registering images from microfilm, an explanation of the operation for registration accompanying the medium conversion from microfilm to an optical disk, then an explanation of the operation for starting or restoring based on the backup method shown in Figure 755, and Next, we will explain the backup method and operation for recovery in a system equipped with a backup-only optical disk.

<Data Structure of Optical Disk> Now, the relationship between the search information media is as shown in FIG. 5, and the relationship between the image file and the search information record in the optical disk file 40 is as shown in FIG. In FIG. 6, the optical disk file 40 stores, for example, four image files (their keywords 66 are part name, part name, parts, and parts catalog). ADD field 6 of those image files
2 are "lFFFF", "IEFFF'", and "1O" respectively.
FFF”, “IcFFF”, where ADD6
2 is 5 digits for convenience, and its MSD is the drive number of the optical disk file 40. That is, in the example of FIG. 6, the drive number is 1°. In FIG. 6, the addresses of the optical disk file 40 have high addresses from the top to the bottom of the page. Normally, low addresses are more reliable and are used to store important data such as search information records. In addition, there are two image files with the same keyword name (゛°parts'°) in the figure, but these have the address °'lFFF.
For example, the image file "F" has undergone image processing and is registered as a new image file with the same keyword 66.0 The optical disc of this embodiment is a so-called write-once type, and the old file cannot be deleted, so it is registered as a new image file with the same keyword 66. The ability to mix old and new files is an advantage of optical discs, as is their large capacity.In other words, the history can be traced from search information records.Images on optical discs Usually, a file search is performed by reading all the search information records in the ID2 or the optical disk, and displaying the read search information records one after another on the CRT 4 while leaving the selection of the search information record to the operator.

(Registration of Image from IS 31) FIG. 7 is a diagram illustrating the concept of the operation in which an image is read by IS 531 and stored and registered in optical disc file 40. According to FIG. 7, the document read from l531 is temporarily stored in the control unit 1 (IMEMll), the keyword 66 input by the operator through the KBD6 without visually checking the CRT4 is registered in the ID2, and the image is transferred to the optical disk. It is stored in file 40. At this time, the search information in the HDZ is backed up on the optical disk file 40.

The above is an outline of the image file registration from 1531. Next, the registration control procedure will be explained according to the flowchart of FIG. In the flowchart of FIG. 8, examples of the screen of the CRT 4 are illustrated at steps as necessary.

After setting the image original to be registered on the optical disc in the 1531, the registration volume is specified in step S2. This registered volume is the ID (name) of the optical disc, etc. Next, in step S4, according to the instructions displayed on the CRT 4, set the image reading mode (image file attributes) 1, for example, resolution (=200dpi/300dpi/400dp
i) Specify the document size (A3.A4.B3.B4) using the PD5 via the menu screen. In step S6, the image is changed to l53 according to the specified attribute.
1 and temporarily stored in IMEMII in 1w5to. The data stored in IMEMII is converted for display by the BMU 16 in step S8 and displayed on the letter.
CRTI F l S (7) VRAM4. :M is stored and displayed on CRT4. The operator looks at the displayed image [1] and confirms whether it has been read correctly. If the image has been read correctly, it is determined in step S12 whether the image just read is one page or the first page of a plurality of pages. This can be easily determined from the operator's instructions or the attribute designation made in step S4. This kind of judgment is also made on the first page when keyword 66 is used.
This is to set. Now, if it is determined in step 312 that the page is one page or the first page of multiple pages, a keyword 66 is set in step S14, and the input keyword 66 is temporarily stored in the DMEM 20. As mentioned above, the human power of keyword 66 is performed through PD5 or KBD6 while visually checking CRT4, DMEM20
Store it in.

After the keyword 66 is entered, the keyword 66 along with other information is shown in Figure 4 (
The search information record is formatted as shown in b) and entered into the search information record HO2 in step St6, and the process proceeds to step 518. When the determination in step S12 is NO, the process immediately advances from step S12 to step 518. When the storage of the search information record in HO2 is completed, wsto is started using the end icon using the PD5, and in step S1B,
The image information temporarily stored in MEMII is transferred to the ICU 18.
and write to the optical disc via 0DIF12.

Repeat the above operation until all pages are completed (step 520)
, when all pages are completed, the search information record of the image document is stored in the optical disk file 40 as a backup in step S22. At this point, as shown in FIG. It will be remembered. If so,
Even if the search information record of the image information is destroyed due to some trouble in the HO2, the same search information record exists on the optical disk file 40, so it can be easily restored.

Other information added to the keyword 66 in the search information record includes information on whether the image information is an optical disc or microfilm, address information on where on the optical disc it is stored, and A4. Size information such as A3, resolution information, compression in ICU l8, etc., i.e. the amount of information stored on the optical disk and whether it is negative information or positive information, etc.
io is added to the beginning of the search information record based on information from the conversation with the operator and information from the optical disc.

(Registration from an optical disc) What has been described above is registration from the 1531, but as mentioned above, it is conceivable that a trader or the like may register from an optical disc on which an image has already been written. In this case, the keyword 66 may be written on the FPD or the like by the vendor in the same way as an image is written on an optical disk. In this case, in step S6 in FIG.
Load search information from PD3, and set keyword 66 and HO of search information each time it is loaded.
2 and backup to an optical disk.

(Registration of microfilm file) Registration of microfilm is usually done by reading the microfilm image that has already been made into film from the MS51.
A search information record including a cartridge number and a frame number list is created and registered on HO2. An outline of the operation is shown in FIG. The feature of this embodiment is that the search information record is registered in the HD2J:, and the search information record for /hookup is also stored in the FPD3.

Figure i10 is a flowchart showing the order of microfilm registration control. When operating a microfilm file, an operator first sets each cartridge in the loading section 54 as shown in FIG. . -f Microfilm file registration differs from optical discs in that the frame number of the microfilm L is used as an absolute address. Also, since the microfilm file is a sequential file, if one search information record is given to a plurality of frames of microfilm that should have the same consecutive keywords 66, the area of HO2 can be reduced.

The control f order when the MA52 is not used will be explained according to FIG. 1O. First, a microfilm cartridge containing image information for which the keyword 66 should be registered is set in the loading section 54, and the image reading mode (image attribute) is instructed in step S30, similar to the image scanner (IS) input described above. . Reading is started in step S32, and the read image information of one frame is temporarily stored in IMEMll, and displayed on the CRT 4 in step S33.

Check whether the reading was normal in the same way as when registering from l531 (Step 534), Step S3
In step 6, it is determined whether the image file is one frame or continuous frames. In step 340, the operator issues the HO-word 66 instruction, and in step S42, the search information record is stored in HO2. In step S44, a backup of the search information record is taken on the FPD 3.

For the first image information, the operator specifies the frame number of the microfilm, and if the information is to be registered sequentially, step 530
All you have to do is add +1 to WSIO in ADD Fieldro 2 and advance the microfilm by one frame, and if you want to record the search information of manually-powered images intermittently, specify the frame number each time. Once registered in HO2, all search information records are managed in HO2, similar to the above-mentioned optical disc.

Registration of a composite image> Next, according to FIGS. 11(a) to (d), the image read from the microfilm and the image read from the optical disk file are combined, and the combined image is registered and the search information record is backed up. I will explain about it.

First, in step S50 of FIG. 11(a), an image is input from a microfilm, and then in step S52, an image is input manually from the optical disc file 40. Step S
50 and step 352 are subroutines whose details are shown in FIGS. Figure (d)) is executed.

The search subroutine searches HO2 for a search information record having the specified keyword 66 (step 5).
80). The searched search information record is stored in the DMEM 20 (step 582), and in step 384 it is determined whether the image is in the microfilm file 50 or the optical disk file 40 based on the value of DEVID 61 in the search information record.

Identification-2-riDEV-ID61 (7) [
f ka” 1 ” teT.

If so, the image is in microfilm file 50.
address information A of the search data.
According to the DD 62, a corresponding image frame in the microfilm file 50 is searched (step 586), and the image of the searched microfilm frame is read (step 588).
The optical disk file 40 is searched according to the address information ADD (step 590), and the image file is read (step 592).

The image information read from the microfilm file 50 or the optical disk file 40 is sent to the workstation 1.
One page is stored in IMEMII 0 (step 594
). This ends the search subroutine.

Returning to step S54 in FIG. 11(a), the IMEMI
Process the two images in I. This processing is performed by BMU.
16. If this processed image needs to be registered, the process proceeds to step S60, where the keyword 66 is set in order to create a new search information record, and - the processed image is stored in the optical disk file 40 at step S62. In step S64, a new search information record is stored in HO2, and in step S66, a backup of the search information record is stored in the optical disk file 40. To put the operations shown in FIGS. 11(a) to 11(d) in accordance with FIG. By combining the images, a new image file "parts catalog" is created on the optical disk file 40 (FIG. 12).

Incidentally, in the above explanation, the combination of images on a microfilm and an optical disc was explained, but it is also possible to transfer an image from a microfilm to an optical disc in the same way.

<Backup file load> Backup file load means, for example, when the search data on the HDz is destroyed due to a failure or the like, or during the initial processing of the JOB program in the embodiment described later, the backup file is loaded from the optical disk file 40 and FPD 3 as shown in FIG. As <H
This refers to the operation of reconfiguring search information records on O2.
FIG. 13 shows the concept of its operation, and FIG. 14 is a flowchart of its control procedure.

According to FIG. 14, first, in step 5100, the optical disk and FPD 3 to be restored are set in the drive. In step 5102, all search information records of the set optical disc are read and stored on HO2. This operation is performed for all optical disks that require restoration. Next, in step 3106, the search information record of the microfilm file 50 is similarly restored from the FPD 3. In this way, the search information record can be completely restored.

<Deleting and restoring search information records> Although the above control procedure shows the method of restoring all search information records, it is extremely difficult to specify a specific keyword 66 and restore only the search information records that have that keyword 66. It's in the tube. An example of this is deletion of a portion of a search information record and restoration of the deleted search information record from a backup. Figure 15 shows an example of deletion. In this case, deletion is performed using search information on HO2.
16(a) and 16(b) show flowcharts of control procedures for deletion and restoration of search information records, respectively. To create an information record, first set a keyword 66 on the CRT4, and
The search information records in the HDZ with the keyword 66 are displayed on the CRT 4, and the operator deletes the desired search information record (FIG. 16(a)).The deleted search information record can also be restored by setting the keyword 66. 6
6. Save the search information record obtained from 6 to optical disk file 40.
Or search and restore in FPD3 (16th
Figure (b)).

<Effects of the above embodiments> In this way, the format of the search information records for the optical disk file 40 and the microfilm file 50 is made common, and the search information records for both files are mixed and stored in the common HD 2, so that the image search The operator who performs this search can search for keywords corresponding to the image to be searched without considering the file to be searched for.
By inputting 6, the desired image information can be obtained.

That is, since the file (medium) in which the image is actually recorded and the address within that file are managed in the search information record, the operator does not have to be aware of the composite medium when searching for an image. This makes it easy to centrally search for images. Also, backup of search information can be done using an optical disk or FPD3.
Since the search information is prepared for, it is easy to restore the search information, and management is ensured by distinguishing the backup media.

Furthermore, with backup, you can safely delete infrequently used or outdated search information, which frees up free space on your hard disk and allows you to search for keywords for new image information. can be registered.

Composite image file system with a dedicated backup optical disk> In the image file system explained above, the backup of the microfilm search information record is performed on the FPD3.
The backup of the search information record of the optical disk file 40 was stored in the optical disk. In the composite file system described below, the above-mentioned search information records (including search information records for both a plurality of optical disks and microfilms) are stored in an optical disk exclusively for backup. The advantages of providing such an optical disk exclusively for backup are as follows. Of course, it goes without saying that image files can also be stored on this backup-only optical disk.

As the scale of the composite file system increases, the number of optical disks and microfilms increases.

In such cases, do not use optical discs or microfilm! There are many cases in which an optical disc or microfilm is used exclusively for that job by dividing it into 1c (JoB)fi.Furthermore, if there is a table of contents or monthly job for the same job, the job is created with the latest date and time or monthly file structure. You may want to do this.

In addition, there may be cases where it is desired to restart the JOB on the date of the special award. This takes advantage of the characteristic of optical discs that image files are stored one after another without being updated.

In such a case, if the search information records for each job or date and time (monthly) are backed up on a backup-only optical disk, the operator will not have to worry about which optical disk and microfilm are required for each job. All you have to do is read out the search information on the backup-only optical disk and process it.Furthermore, if you also store the program for the job on the backup-only optical disk, only the initial start program will reside on the HD2. J at the desired point in the cylinder.
You can restart OB.

Further, in a normal image file system, as described above, it is essential to register keywords of image files. Since this registration work is a large amount, usually once registration is done in t(D2h), various JOB blocks share and use the search information on HO2.

Since these files are shared, it becomes difficult to manage files for each JOB program and each date as described above.

Further, these search information are not stored in an equivalent system, but are simply stored in the order of registration.

<Outline of JOB program) An optical disk exclusively for backup is proposed based on the above requirements. Therefore, the JOB program of the composite image file system proposed in the tree embodiment has an outline as shown in FIG. 24. In other words, as shown in FIG. It is assumed that a backup file of search information for image files on microfilms and optical discs has already been created according to the L method in the example. First, the JOB program copies these backup files onto the IDZ (as search information used by the JOB program).

When the JOB program ends, all search information on the HDZ is copied again to the backup optical disk.

The backup file copied to the backup-only optical disk is stored as search information belonging to that JOB program. Such backup files for each JOB program are stored one after another in the optical task dedicated to backup each time a different JOB program is run. Since optical disks have a large capacity, they can withstand storing such backup files. When running the same JOB program, search information with the JOB program name is called from the backup optical disk onto the HDZ, and image files are searched and reprocessed according to the search information.

Here, if we explain according to the flowchart in Fig. 23,
In step 5170, the search information storage area on HO2 is cleared. In step 5172, it is determined whether the JOB program is an initial start. If it is an initial start, the process of loading the backup file described above (FIG. 14) is executed in step 5174. In step 5100 of this backup file load, the relevant JOB
Just load the necessary floppy disks and optical disks into the drive, and with this backup file rotor you can
Search information with the OB program in the middle is reconstructed on HO2. The business process is performed in step 3178 using this search information, and in step 3180, the latest search information that is expanded on the HDZ is copied to the backup optical disk (Figure 20) (details of this flow). (described later), therefore, when restarting the JOB program, the answer at step 3172 is NO,
In step 5176, a warm restart (FIG. 22) is performed. This warm restart is to reconstruct the search information on the HO2 from the backup file on the backup-only optical disk, as will be described later.

This is all the search information for optical disc files or microfilms used for. The JOB program 83 stores the JOB program. JOB record 84 indicates that another JOB record and search information record newly follow.

Storing on a backup-only optical disk> Storing a backup file on a backup-only optical disk takes priority into consideration.

FIG. 19(a) shows the number of each drive of the optical disks connected to this composite image file system. The total number of optical disks connected to the combined file system is, for example, eight at most. FIG. 19(b) shows flags in the DMEM 20, and each flag indicates whether or not the corresponding optical disk drive is currently being used.

FIG. 20 is a flowchart illustrating the order of determining which drive should be loaded with a backup-only optical disk under the optical disk configuration of FIG. 19. The reason why such flowchart control is necessary is to take into consideration the operator's usability when a large number of optical disk drives are connected as shown in FIG. 19. That is, WS 1
0 independently determines the drive in which the backup-only optical disk should be loaded at the most convenient position from the operator's point of view, displays the drive number on the CRTa, and prompts the operator to load the backup-only optical disk.

First, in step 5110, it is checked whether all drives are empty.

If all the drives are empty, a message is displayed on the CRT 4 in step 5112 saying, ``Load a backup-only optical disk into the drive numbered 0.degree.''. ”
Drive number o'' is chosen because it is closest to the operator.

If the backup-only optical disk is loaded into the drive numbered "0," a subroutine for saving to the backup-only optical disk is executed in step 5126. If any optical disk drive is in use in step 5iio, it is checked in step 5116 whether all optical disc drives are in use. If all the drives are in use, for the same reason, in order to load the backup optical disk into drive number ゛0゛°, r”Q
The message "Please change the drive number" is displayed on the CRT.
4 Display on top. In step 5116, if any drive is free, identify the drive closest to the operator (the drive with the lowest number);
The message ``Load a backup-only optical disk into the drive'' is displayed on the CRTA. All of the above judgments are made with reference to the flags in FIG. 19(b).

FIG. 21 shows the save subroutine. 720 details of step 5126 in diagram 720. First, in step 5128, it is determined whether the loaded optical disc is a backup-only optical disc. This can be determined by examining the disc type record (Fig. 17(b)). Step 5130~
JOB record in step 5134 (Figure 17 (C))
is set, and in step 5136 the JOB record is written to the backup-only optical disk. Next, step 5
138. In step 5140, the search information record (i17

As mentioned above, this embodiment differs from the embodiment shown in FIG. 5 in that it also writes a microfilm search information record.

(Warm restart) Warm restart reads the JOB record, search information record, etc. from the backup optical disk.
The job is expanded on the HDZ and the job is restarted. This restart is suitable for a system in which optical disks or microfilms used for each job are used for different jobs. The operator of that JOB can call up all search information from the backup-only optical disk using the JOB record corresponding to the JOB. Since this search information is backed up, there is no need to register the search information in Cf for each job, and the image file system can be easily used. It is also effective when data on the HDZ is unreliable.

FIG. 22 shows a flowchart of the warm restart control procedure. When this control program is stored in HO2, it is called from HO2 to PMEM9, but HO2
First, in step 5150, the drive number of the optical disk in which the backup-only optical disk is loaded is designated from the CRT 4. After confirming that the optical disc loaded in the drive is a backup-only optical disc (step 5151), in step 5152, the user enters the name and date of the restart. The JOB record corresponding to the 308 people input in step 5154 is searched in the backup-only optical disk, and if found, the search information record following the JOB record is read out and developed on the HDZ in step 5156. If necessary, the program is also read out and expanded on the HDZ in step 5158. In this way, the retrieved information record can be very easily restored in the desired system configuration that matches T l > B. Operator is JO
By displaying the volume name in the B record on the CRT 4, you can know what kind of optical disc and microfilm are needed for the job, so you can prepare the optical disc or microfilm according to the display.

Effects of the embodiment having a backup-only optical disk> As explained below, by using an image file system having a backup-only optical disk, (1) all search information and even programs can be stored.

■The file structure of the image file system can be reconstructed from a copy of the search information managed in the JOB record in the backup-only optical disk.
JOB=file management for each 1+'T becomes possible. That is, it becomes possible to systematize file management oriented toward JOB programs.
