"1" indicates automatic, and "2" indicates selection. In the immediate case, when the title table 60' or page table 61 of the binder is updated, the corresponding title table 62 or true letter 63 of the corresponding super binder is updated immediately. In the case of automatic, at any preset time such as at the end of business, the title expression 62 or true meaning 6 of the corresponding super binder is automatically updated with the updated contents of the subordinate binder.
3 is updated. In the case of selection, when instructed by the operator, the title expression 62 or the true meaning 63 of the corresponding super binder is updated with the updated contents of the subordinate binder. The automatic deletion attribute area h has an automatic attribute indicating whether or not to automatically delete the super binder title 62, shinura 63, binder title table 60, and page table 61 when the magnetic disk 26 is full. The deletion attribute is stored, r
In the case of OJ, it indicates permission h1 for automatic deletion, and if it is "1",
Indicates that automatic deletion is prohibited, and "2" indicates that automatic deletion is permitted and has been deleted. The title west key number area i is designed to store what is brought from the definition of the title structure. The binder definition date area j stores the date on which the binder was defined. The title storage configuration area k stores a title storage configuration indicating whether the title storage configuration is to be in registration order (sequential) or in index order (i-sum) arranged in alphabetical order, etc. ” indicates sequential, and “1” indicates isometric. Next, the definition of the title structure will be explained with reference to a storage example of the title structure management table 64 shown in FIG. In other words, key number “1” is assigned to super binder “2”.

Key number ``1'', key attribute value, and key length of 10 digits are set as key 1, and key number ``2'', key attribute characters, and key length of 15 digits are set as key 2. In this case, binders “11” and “1” are used for super binder “2”.
2" is a subordinate binder and has the same title structure. Next, in such a configuration, the definition of the binder will be explained with reference to the flowchart shown in FIG. First, the operator sets the binder definition mode using the keyboard 23 and specifies whether the super binder name is new or not. If it is new, the CPU 34 checks whether the optical disc 21 is full (overflow). After this confirmation, if the optical disk 21 is not full, the process proceeds to the next step, and if the optical disk 21 is full, the process of deleting the super binder title letter 62 or n letter 63, which is old and is allowed to be deleted, is performed. be exposed. That is, the CPU 34 selects the one in which the type of area C in the binder management table 65 is super binder, the deletion attribute of area h is automatic rOJ, and the binder creation date of area j is the oldest. The deletion attribute of area h corresponding to the super binder is changed to "2" indicating that it has been deleted. This allows the title expression 6 to correspond to that super binder.
2 or the real word 63 is deleted, and the deleted area is used as the area of the title word 62 or the true word 63 corresponding to the new super binder. Next, the CPU 34 inputs the super binder name to the CRT.
You will be guided through the display device 24. According to this idea, the operator inputs the super binder name using the keyboard 23 and defines the title structure. For example, as a title structure, key attribute "0", key length "1o", key name "key 1" are set for key number "1", and key number "1" is set.
2", the key attribute "1", key length r, 15J, and key name "key 2" are set. This set title structure is stored in the title structure management table 64 by the CPU 34.
is memorized. In this case, since it is the second binder, a super binder number "2" is assigned. Next, the CPU 34 displays the title structure change attribute, the presence/absence location of the title idiom, the presence/absence location of the title idiom, the updater attribute, the automatic deletion attribute, the number of keys in the title, the binder definition date, and the human power of the title storage configuration on the CRT display device 24. be done. In response to this guidance, the operator uses the keyboard 23 to set the title structure change attribute to disallowed (0), the title table H is absent, and the location is the magnetic disk 2.
6 (1), I' in table B non-existent location is magnetic disk 2
6 (1), the updater attribute is automatic (1), the automatic deletion attribute is allowed (0), the number of keys in the title is "2", and the binder definition date is r89.1. The IJ and title storage configuration are set to GEKEN SHANEL (1). As a result, C
For the binder number "2" in the binder management table 65, the PU 34 sets "0" as the binder/super binder type, "0" as the binder name/super binder name, and title structure change attribute, as shown in FIG. "2" for title table presence/absence location, "2" for page table presence/absence location
, updater attribute "1", automatic deletion attribute "0"
, "2" as the number of keys in the title, and r89.1 as the binder definition date. IJ, title storage configuration, ``1
' is memorized. If the super binder name is not new, the CPU 34 checks whether the magnetic disk 26 is full (overflow) or not. As a result of this confirmation, if the magnetic disk 26 is not full, the process proceeds to the next step, and if the magnetic disk 26 is full, the process of deleting the title table 60 and n table 61 of the old binder whose deletion is permitted is performed. That is, C
Area C to the west of binder management table 65 by PU34
The type of is binder, and the deletion attribute of area h is automatic "0".
The oldest binder created in area j is selected, and the deletion attribute of area h corresponding to the selected binder is changed to "2" indicating that it has been deleted. As a result, the title table 60. The page table 61 is deleted, and the deleted area becomes the title table 60 corresponding to the new binder. It is used as an area for the page table 61. Next, the CPU 34 searches the binder management table 65, extracts the super binder for which rOJ is set as the binder/super binder type, and displays it on the CRT display device 24. Next, the operator selects one of the displayed super binders or inputs the super binder name using the keyboard 23. CRT by CPU34
Display outfit! At 24, the super binder name is displayed and the user is prompted to input the binder name. In response to this guidance, the operator inputs the binder name using the keyboard 23. Next, the CPU 34 defines the title structure for the super binder. For example, in the case of a binder for super binder "2", the title structure is that for key number "1", key attribute "0", key length "10",
The key name "Key 1" is set, the key attribute "1", the key length "15", and the key name "Key 2" for the key number "2".
is set. This set title structure is CPU3
4 is stored in the title structure management table 26d. In this case, since it is the 11th binder, the binder number "11" is assigned. Next, the CPU 34 prompts the CRT display device 24 to input title structure change attributes, title table presence/absence location, page table presence/absence location, updater attribute, automatic deletion attribute, number of keys in title, binder definition opening, and title storage configuration. be done. In response to this guidance, the operator uses the keyboard 23 to set the title structure change attribute to disallow (0), the title table presence/absence location to the magnetic disk 26 (1), the page table presence/absence location to the magnetic disk 26 (1), and the updater attribute. is automatic (1), the automatic deletion attribute is allowed (0), the number of keys in the title is "2", and the pinder definition date is r89.1. IJ,
The title storage configuration is set to Isamu (0). As a result, the CPU 34 stores the binder number "11" in the binder management table 65 as shown in FIG.
"2" as binder/super binder type, binder name/
Super binder name, "0" as title structure change attribute, "1" as title table presence/absence location, "1" as title table presence/absence location, updater attribute "1", automatic deletion attribute "0", key in title "2" as the number and r89.1 as the binder definition date. IJ and rOJ are stored as the title storage configuration. In such a state, the process of changing the title structure will be explained with reference to the flowchart shown in FIG. First, the operator instructs to change the title structure of the super binder. Then, the CPU 34 checks the content of the title structure change attribute area d corresponding to the currently supported super binder in the binder management table 65, and sets it to "0".
(in this case, submission is prohibited and is not permitted), please indicate that on the CRT.
The display device 24 provides guidance to the operator. Further, when the CPU 34 is "1", it accepts a change in the title structure in the automatic mode, and when it is "2", it accepts a change in the title structure in the selection mode. First, changing the title structure in automatic mode will be explained. That is, the CPU 34 reads out the title structure corresponding to the super binder from the title structure management table 64 and displays it on the CRT display device rIt24. Based on this display, the operator selects key insertion using the keyboard 23 and sets the key name to be changed, the number of keys in the title, etc. t, , S, and the binder management table 6 by the CPU 34.
The stored contents of the number of keys in title area 1 of the corresponding super binder and subordinate binders of No. 5 are changed to the set number of keys. Next, the CPU 34 selects the title table 62 and the title table 60. based on the contents of the title table presence/absence location area e of the super binder and subordinate binders in the binder management table 65. Investigate the existence and existence location of ..., and find out the existence location,
In other words, the title expression 6 stored on the optical disc 21
2 and the title table 60 stored on the magnetic disk 26
,... to the specified structure. Furthermore, CPU34
changes the title structure of the corresponding super binder and subordinate binders in the title structure management table 64. For example, the number of keys in the title of super binder "2" is "2".
” to “3”, the corresponding super binder “2” in the binder management table 65 is changed as shown in FIG.
"The number of keys in the title has been changed from "2" to "3".
The number of keys in the titles of the subordinate binders "11" and "12" is changed from "2" to "3". Next, the title table 62 stored on the optical disk 21 and the title table 60 . ..., the first
As shown in Figure 1, the structure is changed to include an area for key 3. Furthermore, as shown in FIG. 12, the title structure of the key "3" for the corresponding super binder "2" in the title structure management table 64 is additionally stored, and the title structure of the key "3" for the subordinate binders "11" and "12" is additionally stored. ” title structure is additionally memorized. Next, changing the title structure depending on the selection mode will be explained. That is, the CPU 34 reads out the title structure corresponding to the super binder from the title structure management table 64, and displays the title structure on the CRT display! 24. Based on this display, the operator selects key insertion using the keyboard 23 and sets the key name to be changed, the number of keys in the title, etc. Then, the CPU 34 changes the stored content of the number of keys in title area 5 of the corresponding super binder in the binder management table 65 to the set number of keys. Next, the CPU 34 checks the existence and location of the title notation 62 based on the contents of the title table presence/absence location area e of the super binder of the binder management table 65, and determines the location of the title notation 62, that is, the title notation stored on the optical disc 21. 62 to the specified structure. Next, the CPU 34 uses the CRT display device 24 to inform each subordinate binder corresponding to the super binder whether the same title storage structure is to be used and the name of the binder. If this guidance specifies that the title structure be the same, the CPU 34 uses the binder management table 65
The stored content of the key number area i in the title of the corresponding binder is changed to the set number of keys. Next, CPU3
4 checks the existence and location of the title table 60 based on the contents of the binder title table presence/absence location area e of the binder management table 65, and specifies the title table 60 stored in the magnetic disk 26 at its location. Change to structure. Furthermore, if the above guide specifies that the title structure should not be the same, the CPU 34 uses the binder management table 65
The content of the binder/super binder type area b is changed to "-1" indicating a single binder. As a result, that binder becomes an independent binder and is no longer under the control of the super binder. Next, the CPU 34 changes the title structure of the subordinate binder to have the same title structure as the corresponding super binder in the title structure management table 64.

The keyboard 123 is used to manually input various operation commands such as search and editing processing. Further, the mouse 129 can be used, for example, to arbitrarily move a cursor (not shown) displayed on the display window of the CRT display device 124 vertically and horizontally, and to give an instruction at a desired position to determine the position of the cursor. This function selects or instructs display contents (various operation modes, area designations for image editing, icons, etc.). A CRT display device (cathode ray tube display device) 124 displays images retrieved from the center 3. Icons and the like are displayed at the top, bottom, and right ends of the display window of the CRT display device 124. Further, the CRT display device 124 includes one, two
It is a multi-window type display device that can display images simultaneously using one or four windows. Editing processes such as enlarging, reducing, rotating, scrolling, etc. are performed on the images displayed in each display window independently. The printer device 125 is a CRT display device 124
This is to print out the image displayed in ()\-tocoby). Next, the operation of image storage (registration) and search processing in the center 3 will be explained with reference to flowcharts shown in FIGS. 14 to 17. First, image storage processing will be explained. For example, while the menu screen of the CRT display device ff124 is displayed, a predetermined optical disk 20a (20b), that is, a cabinet is loaded, and the registration mode is selected and set using the keyboard 23. Then, the CPU 34 displays a list of binders in the loading cabinet on the CRT display device 24 and guides the selection of binders. When a binder is selected according to this guidance, the CPU 34 opens the selected binder. That is, the CPU 34 determines that the title table 60 is located on the magnetic disk 26 based on the location of the title table presence/absence 47 stored in the area e of the binder management table 65 corresponding to the binder, and the title table 60 is stored in the area f. The location of the page table 61 is determined to be the magnetic disk 26 based on the presence/absence of the page table 61, and the title table 60 and the page table 61 are set in a state where data can be read and written. Next, the CPU 34 reads the title structure corresponding to the binder from the title structure management table 64, and uses the CRT display device 24 to guide the input of search information for both images to be registered based on the read title structure. In accordance with this guidance, each search key in line with the above title structure is input using the keyboard 23. The CPU 34 checks the validity of the input search information according to a predefined format. Furthermore, CPU
34 uses the title table 60 and page table 61 to check for double registration by comparing the search information with the search information already registered on the optical disc 20a (20b). Depending on the result of this check, the input search information is stored in the main memory 38.
is memorized. Next, the original is set on the scanner device 18, and the CPU 34
operates the optical disk device 22a (22b) and the scanner device 18. The scanner device 18 two-dimensionally scans and photoelectrically converts an image of a set document or the like. The line information of this photoelectrically converted image is sequentially stored in the page memory 40. The image stored in the page memory 40 is enlarged or reduced by the enlargement/reduction circuit 46 in accordance with the display size of the CRT display device 24, and then stored in the display memory 42 and displayed on the CRT display device 24. At this time, the resolution of the image is changed using a VRAM (not shown) or the like to match the resolution of the CRT display device 24, and S is stored in the display memory 42. The skew, density, resolution, etc. of the image displayed on the CRT display device 24 are checked, and when the displayed image is satisfactory, a memory key (not shown) is pressed manually. Then, the CPU 34 converts the original image stored in the page memory 40 into a compression/decompression circuit (C0D) for each line information.
EC) 50, the well-known MR (Modi('ie

a (20b). When the storage of the original image on the optical disk 20a (20b) is completed, the CPU 34 uses a search code (
search information) and stored in the main memory 38. Next, the CPU 34 converts the image stored in the display memory 42, that is, the image changed to match the display size (A4) of the CRT display device 24, into a compression/expansion circuit (C0Dr:C) 50 for each line information. ,
Encoding processing is performed by band compression using a well-known MR (Nodified Read) method or the like. This encoded image is supplied to the optical disc device 22a (22b) and stored on the optical disc 20a (20b). When the storage of the image onto the optical disk 20a (20b) is completed, the CPU 34 associates the logical address, that is, the storage address determined from the physical track address and physical sector address where the image is stored, with the above search code (search information) and returns the main It is stored in the memory 38. Also, other images are displayed on the optical disc 20a (20b) in the same manner as above.
), and the search data is stored in the main memory 38. When the registration process is completed, the key bomber 23 instructs the binder to be closed. Then, the CPU 34 reads the title table 60 and hundred table 61 stored in areas e and f in the binder management table 65 corresponding to the binder.
As a result of this determination, if the location is the magnetic disk 26, the search data stored in the main memory 38 is supplied to the magnetic disk device 27. As a result, the magnetic disk device 27 transfers the supplied search data to the corresponding title table 60° page table 61 in the magnetic disk 26.
Updated and memorized. When storing search data in the title table 60, the CPU 34 stores the titles in the order of registration if the title storage structure stored in area k in the binder management table 65 corresponding to the binder is sequential, and in the case of Aisam, stores the data in the order of index. Organize it, rearrange it in alphabetical order, and memorize it. When the title storage configuration stored in area k is "0", it indicates sequential, and when it is "1", it indicates isam. Next, image deletion processing will be explained. For example, now
While the menu screen of the CRT display device 24 is displayed, a predetermined optical disk 20a (20b), that is, a cabinet is loaded, and the deletion mode is selected and set using the keyboard 23. Then, the CPU 34 displays a list of binders in the loading cabinet on the CRT display device 24 and guides the selection of binders. When a binder is selected according to this guidance, the CPU 34 opens the selected binder. That is, the CPU 34 reads the title table stored in area e in the binder management table 65 corresponding to the binder. Based on the non-existing location, the location of the title table 60 is determined to be the magnetic disk 26, and the location of the page table 61 is determined to be the magnetic disk 26 based on the true back H non-existing location stored in area f. Their title table 60. The page table 61 is set in a state where data can be read and written. Next, the CPU 34 reads the title structure corresponding to the binder from the title structure management table 64, and uses the read title structure to manually guide the search information for the image to be searched on the CRT display device 24. In accordance with this guidance, each search key in line with the above title structure is input using the keyboard 23. The CPU 34 checks the validity of the input search information according to a predefined format. Furthermore, the CPU 34 sequentially compares and collates the search information stored in the title family 60 of the magnetic disk 26,
It sequentially checks whether or not search information that matches the input search information is stored, and extracts the corresponding title. Thereby, the CPU 34 stores the title numbers of the extracted candidates in the main memory 38, reads out search data corresponding to these title numbers from the title family 60 of the magnetic disk 26, and displays them on the CRT display device 24. When the desired title and page are selected by this display,
The CPU 34 reads the storage address of the corresponding image corresponding to the selected title and page from the title group 60 and page table 61 of the magnetic disk 26, and reads the physical track address and physical sector address corresponding to the storage address of this image. The optical disc device 2 calculates these addresses and uses these addresses to reproduce the image from the optical disc 20a (20b).

is displayed. After confirming the display, when an instruction to delete the document or page is given, the stored contents of the corresponding title family 60 and page table 61 are deleted. The updated and stored title family 60 and page table 61 are processed in the same manner as in the registration process described above. Next, image search processing will be explained. For example, now
While the menu screen of the CRT display device 24 is displayed, the search mode is selected and set using the keyboard 23. Then, the CPU 34 sequentially reads the super binder whose data is "0" and the single binder whose data is "-1" stored in area b in the binder management table 65, and displays the super binder and single binder list on the CRT display device. 24 to guide the selection of a super binder or a single binder. When a super binder is selected according to this guidance,
The CPU 34 opens the selected super binder. That is, the CPU 34 determines that the title table 62 exists on the optical disc 21 based on the title table presence/absence position stored in the area e in the binder management table 65 corresponding to the super binder, and the title table 62 is stored in the area f. Based on the presence/absence of the title name 63, the location of the title name 63 is determined to be the optical disk 21, and the state is set such that data can be read and written to the title name 62 and the true name 63. Next, the CPU 34 reads the title structure corresponding to the super binder from the title structure management table 64, and manually guides the search information of the image to be searched using the read title structure on the CRT display device 24. In response to this guidance, each search key in line with the above title structure is input using the keyboard 23. The CPU 34 checks the validity of the input search information according to a predefined format. Further, the CPU 34 sequentially compares and collates the search information stored in the title expression 62 of the optical disc 21,
It sequentially checks whether or not search information that matches the input search information is stored, and extracts the corresponding title. As a result, the CPU 34 stores the title numbers of the extracted candidates in the main memory 38, and searches the search data corresponding to these title numbers for the title family r! of the optical disc 21. ! 362 and displayed on the CRT display device 24. At the time of this search, if the search information stored in the title expression 62 is stored in eye sum, the search time becomes faster. When the desired title and page are selected by this display,
The CPU 34 checks whether the cabinet corresponding to the selected title and page is loaded. As a result of this confirmation, if the corresponding cabinet is loaded, the CPU 34 reads out the storage address of the corresponding image from the title notation 62 and [(notation 63) of the optical disc 21, and reads the storage address of the corresponding image from the physical track The address and the physical sector address are calculated, and the optical disk device 22a (22b) reproduces the image from the optical disk 20a (20b) using these addresses. That is, the CPU 34
The image (compressed information) for each scanning line supplied from (22b) is supplied to the compression/expansion circuit 50, subjected to band expansion processing, and sequentially supplied to the display memory 42. As a result, the image stored in the display memory 42 is displayed on the CRT display device 24. Furthermore, if the corresponding cabinet is not loaded, the CP, U 34 loads the corresponding optical disk 20a (20b) into the optical disk device 22a (22b) using an autochanger (not shown), or the CR

0b). When the corresponding optical disc 20a (20b) is loaded in accordance with this guidance, processing is carried out in the same way as when the cabinet is loaded. When the German binder is selected, the search process is performed using the corresponding title front 60 and true back 61, as in the case of the super binder.Furthermore, the CPU 34 executes the registration process, the deletion process, and the end of the search process. When instructed, at the end of business when all processing is completed, or at a time arbitrarily determined by the system such as at night, the updater attributes stored in area f of each binder in the binder management table 65 are automatically updated.

Based on the updated contents of the table 61, the stored contents of the title expression 62 and the true meaning 63 of the super binder of the corresponding optical disc 21 are updated. At this time, the title storage structure of the title expression 62 and the true meaning 63 is taken into consideration and stored in the same manner as described above. Next, image search processing in the terminal device 1a (1b, . . . ) will be described. For example, now terminal device 1a (lb
, . . ) is displayed on the menu screen of the CRT display device 124, the search mode is selected and set using the keyboard 123. Then, the CPU 134 is connected to the CPU 34 via the communication control module 116, the communication line 2, and the communication control module 16, and the start of search processing from the CPU 134 is transmitted to the CPU 34. The CPU 34 sequentially reads out the super binder whose data is "0" and the single binder whose data is "-1" stored in area b in the binder management table 65, and displays the super binder and single binder list on the CRT display device 24. Display and guide the selection of super binder and single binder. When a super binder is selected according to this guidance, the CPU 34 ovens the selected super binder. That is, the CPU 34 selects the binder IeFf! corresponding to the super binder. The location of the title idiom 62 is determined to be the optical disc 21 based on the presence/absence location of the title face stored in area e in the J1 table 65, and the true yakuji 63 is determined based on the location of the jI face presence/absence stored in area f. is determined to be the optical disc 21, and a state is set in which data can be read and written to the title front 62 and true back 63. Next, the CPU 34 reads the title structure corresponding to the super binder from the title structure management table 64, and uses the read title structure to guide the input of search information for the image to be searched to the communication control module 16, the communication circuit t12, and the communication control module 116. The terminal device 1a (lb, ・
...) is output to the display memory 142. Thereby, the CRT display device 124 guides the user to input the search information for the image to be searched. In accordance with this guidance, the user inputs each search key using the keyboard 123 according to the title structure. The CPU 34 checks the validity of this input search information according to a predefined format, and sends it to the CPU 34 via the communication control module 116, the communication line 2, and the communication control module 16.

By instructing the cabinet name to be searched on the display device 24, the optical disc 20a (20
b) Guide. When the corresponding optical disc 20a (20b) is loaded in accordance with this guidance, the same processing as when the cabinet is loaded is performed. Also, when the I11-only binder is selected according to the selection guide for the super binder and single binder, the search process is performed using the corresponding title family 60 and true back 61, as in the case of the super binder. The process of searching for an image from the optical disk 20a (20b) of the center 3 in the terminal device 1a (lb, -...) is as follows:
This can be done when the center 3 is performing registration, deletion, and search processing. However, when the center 3 is performing registration or deletion processing, search processing in the same binder that is performing the processing is prohibited. As mentioned above, the center and multiple terminal devices are connected via a line, and the center stores multiple images on an optical disk in a four-layered structure of cabinet, binder, document, and page, and also stores these images on an optical disk. Search information consisting of a plurality of keys for searching each corresponding image is stored on a magnetic disk with a different title structure for each binder, and the desired image can be retrieved from the above by specifying the search information stored on this magnetic disk. In the case where a super binder is searched from an optical disc and has multiple binders with the same title structure of the above search information placed above the cabinet, the above host sets the title expression of the super binder separately from the binder. The super binder is stored on a rewritable optical disc separate from the optical disc, and when searching for an image on the host side or the terminal device side, the title front and back of the super binder stored on the rewritable optical disc are used. When registering or deleting an image on the above host side, the title front and true back of the binder stored in the magnetic disk are updated, and the updated contents of the title front and true back are collected later, for example, at night. The titles are stored in the title and 100 titles of the corresponding super binder of the rewritable optical disc. As a result, when performing search processing using a super binder using a terminal device, registration and deletion processing using the binder can be freely performed on the host side, and registration and deletion processing using the binder can be performed on the host side. During the processing, the terminal device can freely perform search processing using the super binder. That is, registration and deletion processing by the host and search processing by the terminal device can be separated. In addition, the registration performance of rewritable optical discs that store super-binder title expressions is generally poor, but at night, etc.
Since the updated contents of each binder are transferred to a rewritable optical disk, performance problems can be solved. Also,
It is possible to prevent the capacity of a magnetic disk from decreasing due to the title front and back of the super binder. In addition, the title structure of the title expression of the super binder is an eye sum suitable for high-speed search, and the title structure of the title table of the binder is sequential, suitable for high-speed registration. This allows the title tables of the super binder and the binder to have an optimal storage configuration. [Effects of the Invention] As detailed above, according to the present invention, when images are being registered at the center, search processing can be performed from the terminal device, and search processing from the terminal device can be performed. It is possible to provide an electronic filing system that allows images to be registered at a center when the user is at the center.
