A serial number is assigned to the binder/super binder number area a regardless of whether it is a binder or a super binder. The binder/super binder type area b stores the type indicating whether it is a binder or a super binder. In the case of rOJ, it indicates a super binder, "-1" indicates a single binder, and "1" indicates a super binder. In the above cases, the binder is indicated and the number of the super binder to which this binder belongs is indicated. In the title structure change attribute area d, there is a title structure change attribute that indicates whether or not title structure change is permitted, and if so, whether the change process is performed automatically or selectively. rOJ indicates disallowance, "1" indicates permit n1 and automatic change processing (automatic mode), and "2" indicates permit and selective It shows change processing (selection mode). In the automatic mode, when the title structure of the super binder is changed, the title structures of all binders under it are also automatically changed. In the selection mode, when changing the title structure of a super binder, the user selects whether or not to change the title structure to the same title structure for each binder below.

In the immediate case, when the title table 60 or page table 61 of the binder is updated, the title cover 62 or page table group 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 cover 62 or page table group 63 of the corresponding super binder is automatically updated with the updated content of the subordinate binder.
is updated. In the case of selection, when instructed by the operator, the title cover 62 or page table group 63 of the corresponding super binder is updated with the updated content of the subordinate binder.

In the automatic deletion attribute area h, when the magnetic disk 26 is full, the title table e3b 2 of the super binder and the sada cover material 63 are stored.
, binder title table 60. An automatic deletion attribute indicating whether or not to automatically delete the page table 61 is stored; in the case of rOJ, it indicates permission for automatic deletion; in the case of "1", it indicates prohibition of automatic deletion; In the case of "2", it indicates that automatic deletion is permitted and the deletion has been performed.

The title west key number area i is designed to store the information brought from the definition of the title structure. In the binder definition date area j, a date with which the binder was defined is stored. The title storage configuration area k stores a title storage configuration indicating whether titles are stored in sequential order or in index order (i-sum), which is arranged exclusively in alphabetical order. 0”,
Indicates sequential, and if it is "1", it 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 attribute value, key length 10 digits key 1 is set, and key number "2", key attribute character, key length 15
Digit key 2 is set. Binder "11" and "12"
Key 1 with key number ``1'', key attribute value, and key length of 10 digits is set, and key 2 with key number ``2'', key storm character r, and key length of 15 digits is set for be done. In this case, binders “11” and “
12'' is the binder of the device 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 magnetic disk 26 is full (overflow) or not. After this confirmation, if the magnetic disk 26 is not full, proceed to the next step, and if the magnetic disk 26 is full, delete the title cover 62 or page cover 63 of the super binder whose disappearance is allowed n1. Processing takes place.

That is, the binder management table 65 is
The type of area C in the west is a super binder, the deletion attribute of area h is automatically "0", and the one with the oldest binder creation date of area j is selected and corresponds to the selected super binder. The deletion attribute of area h is changed to "2" indicating that it has been deleted. As a result, the title cover material 62 or page table group 63 corresponding to that super binder is deleted, and the deleted area is used as the area of the title cover material 62 or page table group 63 corresponding to the new super binder. .

Next, the human power of the super binder is transferred to the CRT by the CPU34.
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 "10", key name "key 1" are set for key number "1", and key number "1" is set.
2", a key attribute "1", a key length "15", and a key name "key 2" are set. This set title structure is stored in the title structure management table 64 by the CPU 34. In this case, the binder is No. 2 [l, so the super binder number "2" is assigned.

Next, the CPU 34 inputs the title structure change attribute, title large group H absent location, page table group presence/absence (f: location, updater attribute, automatic deletion attribute, number of keys in title, binder definition 11 included, and title storage configuration). You will be guided by the CRT display device 24. According to this guidance,
The operator uses the keyboard 23 to select the title structure change attribute as unknown n1 (O), title table presence/absence location as magnetic disk 26 (1) representative presence/existence location as magnetic disk 26 (1), updater attribute as automatic (1), and automatic deletion. Attribute is allowed (0), number of keys in title is "2",
Binder definition 11 is included in r89.1. The IJ and title storage configuration are set to GEKEN SHANEL (1). As a result, the CPU 34 sets the binder number "2" in the binder management table 65 to "0" as the binder/super binder type, "0" as the binder/super binder name, and "title structure change attribute" as shown in FIG. "O", "1" for the title front presence/absence location, "1" for the true back presence/existence location, "1" for the updater attribute, "0" for the dynamic deletion attribute, "2" for the number of keys in the title, "89" for the binder definition date. .1.IJ, "1" is stored as the title storage configuration.

If the super binder name is not new, the CPU 34 checks whether the magnetic disk 26 is full (overflow). 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 front 60 and the back 61 of the binder which is old and whose erasure is permitted is performed. That is, C
Area C in the binder management table 65 by PU34
The type of is binder, and the deletion attribute of area h is automatic rOJ.
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 front 60 and right back 61 corresponding to the binder are deleted, and the deleted areas are used as the title front 60 and right back 61 areas corresponding to the new binder.

Next, the CPU 34 searches the binder management table 65 and retrieves the super binder for which "(J" is set as the binder/super binder type) and displays it on the CRT display device 24.The operator then uses the keyboard 23 to display the super binder. Select one of the super binders or enter the super binder name manually.
When the super binder name is displayed on the T-display device W24, the manual of the binder name is also displayed. In response to this guidance, the operator inputs the binder name using the keyboard 23.

Next, the CPU 34 defines the same title structure as 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, quality table presence/absence location, updater attribute, automatic deletion attribute, number of keys in title, binder definition date, and title storage configuration. Ru.

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), automatic deletion attribute is allowed 111 (0), number of keys in title is "2", binder definition date is r8Q, 1. I
J, title storage configuration is set to Isamu (0).

As a result, the CPU 34 causes the binder management table 6
5, the binder number "11" is χ-t L, and as shown in FIG. 7, the binder/super binder type is "2",
Binder name/super binder name, "0" as title structure change attribute, presence or absence of title table? j location is "1", page table presence/absence (l location is "1", updater attribute "1"
", rOJ as the automatic deletion attribute, "2" as the number of keys in the title, "89.1.IJ" as the binder definition 11
, "0" is stored as the title storage configuration.

In this state, the process of transforming the title structure will be described 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 contents of the title structure change history area d corresponding to the currently supported super binder in the binder management table 65, and
In the case of
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 24.

Based on this display, the operator selects key insertion with the keyboard 23 and sets the name of the key to be changed, the number of keys in the title, etc.

Then, the CPU 34 changes the stored contents of the number-of-keys-in-title area i of the corresponding super binder and subordinate binders in the binder management table 65 to the set number of keys.

Next, the CPU 34 selects the title cover material 62 and the title table 6 according to the contents of the title table presence/absence 7j location area e of the super binder and subordinate binders in the binder management table 65.
The existence and location of 0, . ...
Transforms into the specified structure. Furthermore, the CPU 34 changes the title structure of the corresponding super binder and subordinate binders in the title structure management table 64.

For example, the number of title west keys for the 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 cover material 62 and the title table 60. which are stored on the magnetic disk 26 or the optical disk 21. . . changes to a structure in which an area for key 3 is added, as shown in FIG.

Furthermore, as shown in FIG. 12, the key "3" for the corresponding super binder "2" in the title structure management table 64 is
” title structure is additionally memorized and the subordinate binder “11
”, the title structure of key “3” for “12” is additionally stored.

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 it on the CRT display device 24.

Based on this display, the operator selects key insertion using the keyboard 23 and sets the name of the key to be changed, the number of keys in the title, etc.

Then, the CPU 34 changes the storage contents of the number of keys in title area i of the corresponding super binder in the binder management table 65 to the set number of keys.

Next, the CPU 34 checks the presence/absence of the title sheet 62 and the presence location of the title cover material 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 presence location, that is, the magnetic disk 26 or the optical disk 21.
The stored surface material 62 is converted into a specified structure.

Next, the CPU 34 determines whether or not to have an I, ij-title structure for each subordinate binder corresponding to the super binder, and inputs the binder name to the CRT display device l\24.
I will guide you. If the same title structure is specified by this guidance, the CPU 34 changes the stored content of the number of keys in title area i of the corresponding binder in the binder management table 65 to the set number of keys. Next, CP
U34 checks the presence or absence of the title table 60 and the location of the binder based on the contents of the binder title table presence/absence/location area e of the binder management table 65, and determines the presence/absence of the title table 60 and the location of the binder, that is, the location stored in the magnetic disk 26 or the optical disk 21. The existing title table 60 is converted into a specified structure.

Further, if it is specified that the I, J-title structure is not used according to the above guidance, the CPU 34 changes the contents of the binder/super binder type area b of the binder management table 65 to I1.
Change it to "-1", which indicates a one-doku binder. This results in
The binder becomes a tll-only 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.

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 24 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 reads the binder list in the loading cabinet as C.
It is displayed on the RT display device 24 to guide selection of the binder. When a binder is selected according to this guidance,
CPU 34 ovens the selected binder. That is, the CPU 34 determines the location of the title table 60 based on the title table presence/absence H location stored in area e in the binder management table 65 corresponding to the binder, and determines the page table stored in area f. The presence/absence of the page table 61 ([The location is determined and the data is set to be readable and writable for the title table 60 and page table 61.
If the data is "1", it is determined that the disk is the magnetic disk 26, and if the data is "2", it is determined that the disk is the first disk 21.

Next, the CPU 34 reads the title structure corresponding to the binder from the title structure management table 64, and uses the CRT display Wt24 to manually guide search information for images to be registered using the read title structure. In accordance with this guidance, the user inputs each search key using the keyboard 23 according to the title structure. The CPU 34 checks the validity of this manually generated search information according to a predefined format. Furthermore, CP
Using the title table 60 and page table 61, U34 compares the search information already recorded on the optical disc 20g (20b) to check for double registration. Depending on the result of this check, the input search information is stored in the main memory 3.
8 is stored.

Next, the original is set on the scanner device 18, and the CPU 34
operates the optical disk device 22B (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. This photoelectrically converted F! The line information of the il 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 CRT display device 2

).

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 sends 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, to a compression/expansion circuit (C0DEC) 501. :Ite, well known 0) Encoding processing is performed by band compression using the MR (Nodified Read) method or the like. This encoded image is sent to the optical disk device 22 a (
22b) and stored on the optical disk 20a (20b).

Image storage on the optical disk 20a (20b) is finished.''
Then, the CPU 34 stores a logical address, that is, a storage address determined from the physical track address and physical sector address where the image is stored, in the main memory 38 in correspondence with the search code (search information).

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 user instructs the user to close the binder using the keyboard 23. Then, the CPU 34 reads the title table 60 and page 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 (j is located in 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 , the supplied search data is stored in the corresponding title table 60, rL in the magnetic disk 26.
Table 61. Updated and memorized. When storing search data in the title table 60, if the title storage structure stored in area k in the binder management table 65 corresponding to the binder is sequential, the CPU 34 stores the search data in the order of registration; They are organized in order, that is, rearranged in alphabetical order and stored. If the title storage configuration stored in area k is "0", it indicates sequential;
In the case of "1", it indicates eye sum.

In addition, if the above (j) location is the optical disk 21, the search data stored in the main memory 38 is supplied to the destination disk device 28.Thereby, the optical disk device 28 transfers the supplied search data to the west of the optical disk 21. The corresponding title table 60 and page table 61 are updated and stored.When storing the search data in the title table 60, the CPU 34 determines that the title storage configuration stored in area k in the binder management table 65 corresponding to the binder is sequential. In the case of ``Aisamu'', the information is stored in the order of registration, and in the case of ``Aisamu'', the information is organized in the order of the index, that is, rearranged in the order of the Japanese syllabary.

Further, if the updater attribute stored in area g in the binder management table 65 corresponding to the binder is immediate "0" or selection "2", the CPU 34 executes the following process.

That is, if the updater attribute is immediate, the CPU 34
determines the super binder number based on the storage contents of area b in the binder management table 65, and determines the location of the title cover material 62 based on the existence/existence location of the title cover material stored in area e corresponding to the super binder. tt depending on the presence/absence of the page/table group stored in area f.
Determine the location of the back and front group 3, and use their title cover material 6

, the stored contents of the title cover material 62 and page cover material 63 are updated with the updated contents of the TL table 61. When storing search data in the title cover material 62, the CPU 34 stores χ・
If the title storage structure stored in area k in the corresponding binder management table 65 is sequential,
They are stored in recorded order, and in the case of Aisamu, they are organized in index order, that is, rearranged in alphabetical order.

When the updater area is selected, the CPU 34 uses the CRT display device 24 to display the title cover material 62 of the super binder,
The page table group 63 is also provided with guidance as to whether or not to be updated at the same time. If update is selected based on this guidance, the title cover 62 and page table group 63 of the corresponding super binder are updated as described above.

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 20g (2L)b), 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 Wt24 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 the location of the title table 60 based on the presence/absence (1 degree) of the title table stored in area e on the west side of the binder management table 65 corresponding to the binder, and determines the location of the title table 60 stored in area f. The existence location of the true back 61 is determined based on the presence/absence of the front side 61, and the state is set so that data can be read and written to the title table 60 and the true back 61.The above existence location is such that the data of area e is "1". In this case, magnetic disk 26
If the data is "2", the optical disc 2
It is determined that it is 1.

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 create search information for the image to be searched using 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 14 checks the validity of this manually generated search information according to a predefined format.

Further, the CPU 34 sequentially compares and collates the search information stored in the title table 60 of the magnetic disk 26 or the optical disk 21, and sequentially checks whether or not search information that matches the input search information is stored. Extract the relevant title. As a result, the CPU 34 stores the title numbers of the extracted candidates in the main memory 38, and retrieves the search data corresponding to these title numbers from the title table 6 of the magnetic disk 26 or optical disk 21.
The data is read from 0 and displayed 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 image corresponding to the selected title and page from the title table 60 and jT table 61 of the magnetic disk 26 or the optical disk 21, and reads the storage address of the image corresponding to the storage address of this image and the physical track address. The optical disk device 22a (22b) reproduces the image from the previous disk 20a (20b) using these addresses.

That is, the CPU 34 uses the optical disk device F1122a (2
The image (compressed information) for each scanning line supplied from 2b) 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.

After confirming the display, when an instruction to delete the document or page is given, the corresponding title table 60, ff
The memory contents of tt61 are deleted. This newly stored title table 6OS table 61 is 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 2 device 24 is displayed, the search mode is selected and set using the keyboard 23. Then, 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 the 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 in accordance with this guidance, the CPU 34 opens the selected super binder.

That is, the CPU 34 selects the title table H non-existence C [existence 7 of the title cover material 62 depending on the location] stored in the area e in the binder management table 65 corresponding to the super binder.
[Determine the location, determine the residence of the true back group 63 based on the presence/absence of the page table stored in area f, and set the state in which data can be read and written to the title cover material 62 and the true back group 63 Let's do it. Above (J: location is area e, if data of f is "1", magnetic disk 2
If the data is "2", it is determined that the optical disc is the optical disc 21.

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 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 this manually generated search information according to a predefined format.

Further, the CPU 34 sequentially compares and collates the title cover 62I of the magnetic disk 26 or the optical disk 21 with the stored search information, and sequentially checks whether or not search information that matches the manually entered search information is stored. and extract the corresponding title. As a result, the CPU 34 stores the title numbers of the extracted candidates in the main memory 38, reads search data corresponding to these title numbers from the title cover material 62 of the magnetic disk 26 or the optical disk 21, and displays the search data on the CRT display device 24. indicate. At the time of this search, if the search information stored in the title cover material 2 is stored in eye sum, the search time will be faster.

With this display, when the desired title, Sada, is selected,
The CPU 34 checks whether the cabinet corresponding to the selected title Xi is loaded or not. As a result of this confirmation, if the corresponding cabinet is loaded, the CPU 34 reads the storage address of the corresponding image from the title cover material 62 and true back group 63 of the magnetic disk 26 or optical disk 21, and stores the storage address of the image corresponding to the storage address of the image. Calculate the physical track address and physical sector address, and use these addresses to write the optical disc 20a.

When 0a (20b) is loaded, processing is performed in the same way as when the cabinet is loaded.

Further, even when a single binder is selected according to the selection guidance for the super binder and single binder, the search process is performed using the corresponding title table 60 and page table 61, as in the case of the super binder.

In addition, when the CPU 34 is instructed to end the registration process, deletion process, or search process, or at a time arbitrarily determined by the system such as at 1 o'clock at the end of the business day when all processes have been completed,
For those whose updater layering stored in area f of each binder in the binder management table 65 is set to automatic "1", update contents of the title table 60 and page table 61 corresponding to that binder correspond. Update the stored contents of the title cover material 62 and page table IJ63 of the super binder.

At this time, title table 60, page table 61, title cover material 62
, the storage location of the true back group 63, and the title storage structure are taken into consideration and stored in the same manner as described above.

Next, image search processing in the terminal device 1a (lb, . . . ) will be described. For example, now terminal device 1a (lb

The CPU 134 checks the validity of the input search information according to a predefined format, and sends the input search information to the CPU 34 via the communication control module 116, the communication unit 112, and the communication control module 16.
Output to.

The CPU 34 sequentially compares and collates the search information stored in the title cover 62 of the magnetic disk 26 or the optical disk 21, and sequentially checks whether or not search information that matches the input search information is stored. Extract the title. As a result, the CPU 34 stores the title numbers of the extracted candidates in the main memory 38, reads search data corresponding to these title numbers from the title table 462 of the magnetic disk 26 or the previous disk 21, and sends the search data to the communication control module 16 and the communication control module 16. The terminal device 1a (lb,.
...) is output to the display memory 142. As a result, the search data corresponding to that title number is displayed on the CRT display device 124. At the time of the above search, if the search information stored in the title cover material 62 is stored in eye sum, the search time is fast.

This display allows you to select the desired title and page, and

That is, the CPU 34 selects the first disk device 22a (22b).
) to 0 (the supplied image (reduced information) for each scanning line is supplied to the compression/decompression circuit 50, which performs area decompression processing and sequentially supplies the original image to the page memory 40. In this way, when all the reproduced 1 ft images are stored in the page memory 401, the CPU 34 interrogates the images via the communication control module 16 and the communication control module 116. As a result, in the terminal device 1a (lb,...), the image supplied via the communication control module 116 is sent to the display memory 142. The images are displayed on the CRT display device 124 using the CRT display device 124.

In addition, if the corresponding cabinet is not loaded, the CPU 34 loads the corresponding optical disk 20a (20b) into the optical disk device 22a (22b) using an autochanger (not shown), or selects a cabinet to search using the CRT display device 24. The optical disc 20a (20b) is loaded by specifying the name of the optical disc 20a (20b).
I'll come up with a plan. According to this idea, the corresponding optical disc 2
When 0a (20b) is loaded, processing is performed in the same way as when the cabinet is loaded.

Further, even when a single binder is selected according to the selection guide of the super binder and single binder, the search process is performed using the corresponding title table 60 and true back 61, as in the case of the super binder.

The process of searching for images from the optical disc 20a (20b) of the center 3 in the terminal device 1a (1b, . . . ) can be performed while the center 3 is performing registration, deletion, and search processes. However, when registration or deletion processing is performed at center 3, I, -1J
-Search processing in the binder is prohibited.

As mentioned above, the center and a plurality of terminal devices are connected via the same line, and the center side stores a plurality of images on an optical disk in a four-story WI structure of cabinets, binders, documents, and n. Search information consisting of a plurality of keys for searching each image corresponding to each image is stored on a magnetic disk with a different title structure for each binder, and a desired image can be searched by specifying the search information stored on this magnetic disk. is searched from the optical disc, and a super binder in which a plurality of binders with the same title structure of the search information is arranged is placed in the upper part of the cabinet, and the above host searches the titles of the super binders, the true group, It is stored on a magnetic disk separately from the binder, and when the host side or the terminal device side searches for an image, the title group and true back group of the super binder stored on the magnetic disk are searched, and the host side searches for the image. When registering or deleting an image, the title front and true back of the binder stored on the magnetic disk are updated, and the new contents of the title front and true back are later added to the corresponding super binder title group and true back group. It is meant to be remembered.

As a result, when performing search processing using a super binder on a terminal device, registration and deletion processing using the binder can be freely performed on the host side, and registration and page deletion processing using the binder can be performed on the host side. When performing addition and deletion processing, search processing using the super binder can be freely performed using the terminal device. That is, the registration, page addition, and deletion processing by the host and the search processing by the terminal device can be separated.

In addition, the title structure of the large group of titles in 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. As a result, the title families of the super binder and the binder can be stored in an optimal storage configuration.
