FIG. 1 is a schematic diagram showing a configuration example of a transmission system for electronic information according to the present invention.

The system of the present invention is roughly divided into a server unit 10 and a client unit 40, and are interconnected by a network NW. Note that a plurality of client units 40 usually exist. Server unit 10
The client unit 40 and the client unit 40 are all general-purpose personal computers including hardware such as a CPU, a memory, a disk unit (a hard disk, a flexible disk, etc.), a printer, a display, a keyboard, and a mouse. Hard disk devices (HD) 20, 50 as recording media are connected, and an OS (Operating System) and various software are installed.

The HD 20 of the server unit 10 has a server program 21 for operating the server unit 10, a distribution program 22 for transmitting electronic information to the client unit 40, and an electronic program to be distributed to the client unit 40. The database 23 is stored. The server program 21 executes a distribution program transmission unit 11, an update date comparison unit 12, a transfer file extraction unit 13, a transfer file arrangement unit 14, a transfer file information transmission unit 15, a CD-ROM It operates as each functional unit of the creating unit 16.

The database 23 stores electronic information, such as an electronic catalog, to be sent to each client unit 40 in a state of being divided into a large number of files, and is operated by the server unit 10 or an external computer. Can be changed, modified, added, etc. The server unit 10 has a CD-R (writable
The CD-ROM (drive for CD-R) 30 for writing electronic information to the CD) is connected to the CD-ROM.
The CD-ROM 62 can be created by the RD 30 writing to the CD-R. This CD-ROM 62 is sent to the user of the client unit 40, for example, by mail.

In this embodiment, the CD-ROM 62 records electronic information to be operated by a computer program, that is, data in a narrow sense. However, the computer program is recorded as data (electronic information). Is also good.

The distribution program transmission unit 11 transmits the distribution program 22 stored in the HD 20 to the client unit 40 when called from the client unit 40. The update date comparison unit 12 is a client unit
When the data of the update date transmitted from 40 (hereinafter referred to as update date data) is received, the data is compared with the update date data of each file of the electronic information stored in the database 23. Transfer file extraction unit 13, the result of the above-described update date comparison unit 12, as a result of a file having update date data newer than the update date data transferred from the client unit 40, in the database 23,
Extract the file as a transfer file. When there are a plurality of files extracted by the transfer file extracting unit 13, the transfer file arranging unit 14 arranges the files with the oldest update date. The transfer file information transmitting unit 15 transmits to the client unit 40 information specifying the files arranged by the transfer file arranging unit 14, such as a file name.

On the other hand, the client unit 40 has an HD 50
Besides, a CD-ROM drive (CDD) 61, a keyboard 65 and a mouse 66 as operation means, and a display device 63 such as
Connected to a CRT display. The CDD 61 is a CD-ROM 62 on which electronic information sent by mail or the like is recorded.
The electronic information is read therefrom, if any.

In the HD 50 of the client unit 40, a client program 51, a database 52,
The INI file 53 is stored. When the client program 51 is executed, the client unit 40 operates as each function unit of the distribution program calling unit 41, the distribution program execution unit 42, and the search unit 47. However,
The delivery program calling unit 41 is a client unit 40
Automatically starts when the browser is started in,
In order for the distribution program execution unit 42 to actually operate, the distribution program calling unit 41 needs to read the distribution program 22 transmitted from the server unit 10.

The database 52 stores the CD-R that has been sent in advance.
The content of the electronic information recorded in OM62 is the server unit
If the content is different from the content of the database 23, the updated file is stored. The INI file 53 normally records the latest update date data among the update date data of each file recorded on the CD-ROM 62 inserted in the CDD 61 and each file stored in the database 52. .

The distribution program calling unit 41 requests the server unit 10 to transmit the distribution program 22, for example, when a browser is started in the client unit 40. The distribution program execution unit 42 executes the distribution program 22 transmitted by the distribution program transmission unit 11 of the server unit 10. This distribution program execution unit 42
By executing the distribution program 22, the client unit 40 further includes an update date data transmission unit 43,
It operates as each functional unit of the transfer file selection unit 44, the download unit 45, and the INI file update unit 46.

The update date data transmission unit 43
Is transmitted to the server unit 10. The transfer file selection unit 44 includes the server unit 10
A plurality of file names included in the transfer file information transmitted from the transfer file information transmitting unit 15 are once displayed on the display device 63, and all selection is performed by operating the keyboard 65 or the mouse 66, or Accepts one or more if specified. The download unit 45 downloads the transfer file selected by the transfer file selection unit 44 from the server unit 10 and stores it in the database 52 of the HD 50. INI
When the download unit 45 downloads the transfer file from the server unit 10 and stores the transfer file in the database 52 of the HD 50, the file update unit 46 rewrites and updates the contents of the INI file 53 with the update date data of the transfer file.

Next, the operation procedure of the electronic information transmitting system of the present invention having the above-described configuration, that is, the electronic information transmitting method of the present invention will be described. Figure 2 shows a CD-ROM
When 62 is created, the database of server unit 10
FIG. 3 shows the information stored in the database 23 of the server unit 10 in a state where the information stored in the server unit 23, that is, the information recorded in the CD-ROM 62, is updated and added thereafter. It is a schematic diagram. 4 and 5
6 is a flowchart of a processing procedure in the client unit 40, FIG. 7 is a flowchart of a processing procedure in the server unit 10, and FIGS. 8 to 10 are schematic diagrams of a display screen of the display device 63.

In the following description, in the CDD 61 of the client unit 40, a CD-ROM 62 created by recording the electronic information stored in the database 23 of the server unit 10 on a CD-R using the CDRD 30 is previously stored. Inserted, and the date of creation of the CD-ROM 62, or a plurality of files recorded on the CD-ROM 62, in other words, stored in the database 23 of the server unit 10 when the CD-ROM 62 was created. The data of the latest date of each creation date or update date is the INI file 53 as the update date data.
Is stored.

Specifically, the database 23 of the server unit 10 stores information composed of a plurality of files as shown in the schematic diagram of FIG.
Assume that -ROM 62 has been created. For example, the server unit
In the 10 databases, the file number is “1123”, the key is “100”, the file name is “price list”, the title is “price list”, and the update date (including the creation date) is “98040”.
1 ", file number" 1124 ", key" 100 ", file name" How to read price list ", title" How to read price list ", file with update date" 980401 ", file number Is "1125", the key is "101", the file name is "Product List", the title is "1998 Product List", the update date is "980401", the file number is "1230", and the key is " 208 "and the file name is" Product
No.208 ", the title is" Gas stove II type ", the update date is" 980325 ", the file number is" 1348 ",
A file with a key of “513”, a file name of “Product No. 513”, a title of “Hot water heater V type”, and an update date of “980320” is stored, and a CD-ROM 62 is created in this state. Suppose.

The search key is "100" in the price list,
It is assumed that “101” is set in the product list, and each code (number) is set for each product. In the example shown in FIG. 3, it is assumed that the update date “980401” is the latest date. Therefore, when the CD-ROM 62 is inserted into the CDD 61 of the client unit 40, the INI file
It is assumed that “980401” is recorded in 53 as update date data.

After the CD-ROM 62 is created from the information stored in the database 23 of the server unit 10 as described above, the files stored in the database 23 of the server unit 10 are updated and their update dates are updated. It is assumed that the data is also updated on the date when the file itself is updated, and that some files are further added and their creation dates are recorded as update date data.

Specifically, the file with the file number "1123" has the key "100" and the file name "Price List", but the title is "Price List" because the contents have been changed. (Revised version) "and the update date has been updated to" 981130 ". The file with the file number "1125" still has the key "101" and the file name "Product List", but the title is changed to "Product List 1999" due to the change in the contents. ”And the update date has been updated to“ 981225 ”. Then, the file number is "1824" and the key is "513
, The file name is "Product No.208", the title is "Change color of water heater V type", the update date is "981201", the file number is "1825", the key is "208", and the file is The name is “Product No.513” and the title is “Gas stove II
It is assumed that a file with the “model replacement” and the update date of “981215” has been added.

First, when the browser is started in the client unit 40 ("YES" in step S11), the distribution program calling unit 41 starts, and the distribution program 22 is called to the server unit 10 (step S12).

In the server unit 10, when there is a call from the client unit 40 ("YES" in step S51),
The distribution program transmission unit 11 reads the distribution program 22 from the HD 20 and transmits it to the client unit 40 (Step S52). When an Active-X program is used as the distribution program 22, the transmission of the distribution program 22 from the server unit 10 to the client unit 40 is performed only once. When a Java applet is used as the distribution program 22, the client unit 40
Is transmitted every time.

Upon receiving the distribution program 22 transmitted from the server unit 10 ("YES" in step S13), the distribution program execution unit 42 of the client unit 40 starts. First, the update date data transmission unit 43 uses the HD50 INI
Update date data "981120" recorded in file 53
And sends it to the server unit 10 (step S
14) .

When the update date data “981120” is received (“YES” in step S53), the update date comparison unit 12 in the server unit 10 stores the update date data “981120” received from the client unit 40 in the database 23. The transfer file extraction unit 13 compares all the files having the update date data newer than the received update date data “981120” according to the comparison result with the update date data of all the files that have been updated (step S54). Extract as a file (step S55). Next, the transfer file arranging unit 14 arranges these transfer files in order from the oldest to the newest update date data (step S56), and the file names of those transfer files as the transfer file information. Transmits to the client unit 40 (step S57).

In the example shown in FIGS. 2 and 3, the file whose content number has been updated is “1123”, the file whose file number is “1125”, and the newly added file number is “1824”. ”And the file with the file number“ 1825 ”are extracted as transfer files.

When the transfer file information transmitted from the server unit 10 is received as described above (step S15)
Is "YES"), and in the client unit 40, the transfer file selecting section 44 displays it on the screen of the display device 63 (step S16). FIG. 8 shows a screen displayed on the display device 63 at this time.
It is a schematic diagram of 63S.

In the example shown in FIG. 8, each of the above-mentioned transfer files is numbered in order of date in the window W0 with a heading "There is the following new information" and a key for the search is provided. , Issue date (update date) and title. This screen 63S shows
To select all of the files displayed in the window W0, select all buttons B0 displayed as "ALL" and 1
Optional selection instruction button B1 displaying "Only necessary information" to arbitrarily select a file or multiple files
And a search selection instruction button B2 displaying "only specific information" for narrowing down by a search key. B3 is a button for canceling the processing.

When the all-selection button B0 is operated on the display screen of the display device 63 with the keyboard 65, the mouse 66, or the like to instruct all-selection ("YE" in step S17).
S "), the download unit 45 starts taking in the transfer file from the file with the oldest update date data in file units (step S18).

When the capture of the transfer file in units of one file is started in this way, the download unit 45 monitors whether or not the capture of one file is completed without interruption (steps S19 and S20). When the loading of one file is completed ("YES" in step S20), the INI file updating unit 46 rewrites and updates the INI file 53 with the update date data of the transfer file whose loading has been completed (step S21). For example, when the transfer of the transfer file No. 1 shown in FIG. 8 is completed, the contents of the INI file 53 are “981130”.

Thereafter, the above processing is repeated until all the transfer files have been taken in ("NO" in step S23), and when all the transfer files have been taken in ("YES" in step S23), this process is repeated. The process ends. At this point, the contents of the INI file 53 are updated date data of the latest file among all files stored in the database 23 of the server unit 10. For example, if there are four transfer files as shown in FIG.
The contents of the INI file 53 are "981225".

If the transfer file is interrupted during the loading of one file due to, for example, a communication error, the battery of the client unit 40 has run out, or a user instruction by operating the stop button B3 ("YES" in step S19) "), A display as shown in the schematic diagram of FIG. 9 is performed on the screen of the display device 63. In this example,
The number of the file that has been imported so far (No. 2 in the example shown in FIG. 9) is displayed together with the heading “Processing has been stopped”, and re-execution for re-execution A button B4 and an end button B5 for ending the processing are displayed.

If the end button B5 is operated in such a display state on the screen of the display device 63 ("NO" in step S24), the process is terminated at that point. In this case, the INI file 53 stores the update date data of the file whose transfer has been completed at that time. However, when the re-execute button B4 is operated (“YE
S "), the distribution program execution unit 42 restarts the distribution program (step S25), and returns the process to step S14.

In this case, the process is returned to step S14, so that the file (the file No. 2 in the example shown in FIG. 8 and FIG. 9) that was finally captured when the capture of the transfer file was interrupted. Since the update date data “981201” of the file is recorded in the INI file 53, after the restart, the file having the update date data thereafter (in the example shown in FIGS. 2 and 3, the file number is “ 18
24 ”and“ 1825 ”) are extracted by the transfer file extraction unit 13 of the server unit 10 as transfer files, and displayed on the screen of the display device 63 of the client unit 40. Therefore, there is no needless processing that the file once taken in is taken into the client unit 40 again.

On the other hand, when the transfer of only a part of the files is instructed in the above step S17, the processing is performed as shown in FIG. When the optional selection instruction button B1 is operated on the screen of the display device 63 by the keyboard 65, the mouse 66, or the like, by directly clicking the line of each file in the window W0 with the mouse 66, the line of the file is inverted, for example. Displayed to indicate that it is selected.
In this way, the selection instruction of one file is repeated only once or a plurality of times (step S31).
(“YES” in step S32), the download unit 45 selects one of the selected files from the oldest one having the oldest update date data.
The transfer file transfer is started for each file (step S33).

When the search selection instruction button B2 is operated on the screen of FIG. 8, the screen of the display device 63 is displayed as shown in FIG.
Is displayed as shown in FIG. In this example, a window W1 for inputting a keyword is displayed together with a heading "Please enter a keyword". For example, as shown in FIG. When input by operation, a file corresponding to the search key “513” in the transfer information shown in the schematic diagram of FIG. 8 is displayed in the window W2. After confirming the display contents of the window W3 and operating the "Start importing" button B6, importing of the file displayed in the window W2 is executed. The button B7 is a button for canceling the search result and stopping the processing.

In any case, as described above, when the transfer file is started to be transferred in file units,
The download unit 45 monitors whether the loading of one file is completed without interruption (Steps S34 and S35). The above process is repeated until all the transfer files have been captured ("NO" in step S36), and when all the transfer files have been captured ("Y" in step S36).
ES "), this process ends.

However, unlike the case where the all selection is instructed, the INI file updating unit 46 sets the INI file 53 even if the loading of one file is completed in step S35.
Is not updated. Therefore, when the full selection is not instructed, the contents of the INI file 53 are maintained in the state immediately before the execution of the distribution program ("980401" immediately after the CD-ROM 62 is sent). The reason is that at the start of the execution of the distribution program, the INI file update unit uses the update date data of some files selected from all the transfer files whose update date data is newer than the update date data recorded in the INI file 53. This is because, when 46 is updated, the next time the distribution program is executed, the transfer file that was not previously selected is regarded as having been transmitted, and cannot be transmitted thereafter.

If the transfer file is interrupted during the import of one file due to, for example, a communication error, the battery of the client unit 40 being exhausted, or an instruction from the user ("YES" in step S34), the process proceeds to step S2.
The process returns to 4 to perform the same processing as when all selection is instructed.

Next, as described above, the user inputs the files recorded on the CD-ROM 62 initially transmitted to the client unit 40 and the files transmitted thereafter and stored in the database 52 of the HD 50. The operation procedure for retrieving desired information (file) and displaying it on the display device 63 will be described with reference to the flowchart of FIG. 11 and the display device of FIG.
A description will be given with reference to a schematic diagram of a display screen 63S of 63.

First, the user operates the keyboard 65 and the mouse 66 on the screen 63S of the display device 63 on which a window W4 for inputting a keyword is displayed together with the heading "Search for information" as shown in FIG. And input a search key in the window W4 (step S71), the search unit 47 searches the database 52 of the HD 50 using the input search key.
(Step S72). If there is a file corresponding to the database 52 of the HD 50 ("YES" in step S73), the search unit 47 displays the file name of the file in the window W5 for displaying the search result on the screen 63S of the display device 63. It is displayed (step S74).

When the file corresponding to the input search key does not exist in the database 52 and when all the corresponding files are searched from the database 52, the search unit 47
Next searches the CD-ROM 62 with the input search key (step S75). If there is a corresponding file on CD-ROM62
