In the course of executing the questionnaire DB registration process, the CPU 101 checks the destination of the questionnaire sheet file and determines whether there is a questionnaire sheet file addressed to the creator (step S707).

If there is a questionnaire sheet file addressed to the creator (step S707; YES), CPU 101
The file is transferred to the program providing server 200 via the transmission control unit 104 (Step S708). On the other hand, if there is no questionnaire data addressed to the creator (step S707; NO), the questionnaire DB registration processing ends.

As described above, according to the program distribution system 1 of the second embodiment, the questionnaire sheet file including the request and impression of the purchaser is transmitted to the distribution server 1.
Since the data is stored in the database in response to the request, the server can consider the result of the questionnaire as a market request for the next product planning, and thereby provide an application or the like that meets the request of the purchaser.

Further, since the questionnaire sheet file is appropriately transmitted to the creator, an educational program or the like in which the request of the purchaser is reflected can be rationally provided. Furthermore, since the questionnaire sheet file is automatically transmitted to the distribution server 100 and the program providing server 200, the server side and the creator can obtain necessary market information without informing the purchaser of the e-mail address and the like.

If the creator wishes, the questionnaire DB of the distribution server 100 may be referred to for a fee. Further, on the server-side homepage, the opinion of the purchaser may be presented as a graph based on the contents of the returned questionnaire sheet file.

[Third Embodiment] Next, a third embodiment will be described. The configuration of the program distribution system according to the third embodiment is substantially the same as the configuration of the program distribution system 1 according to the first embodiment. I will explain while.

The operation of the program distribution system 1 according to the third embodiment will be described below with reference to the flowchart shown in FIG.

First, the purchaser accesses the home page on the server side (step S801). This home page displays the number of accesses from buyers. That is, each time the CPU 101 detects an access from the receiving terminal 300, the CPU 101 updates the access count (step S802), and updates the homepage to present the updated access count (step S80).
3).

FIG. 9 shows the contents of the home page that the purchaser can browse on the display unit 105 of the receiving terminal 300.
This will be described with reference to FIG. As shown in FIG. 9A, an icon indicating a package 901... In which educational programs and the like are packaged for each educational program and the like is displayed on the homepage 900.

The purchaser can download the educational program and the like in a lump by designating the icon of the desired package 901 by clicking with the mouse of the input unit 302. At this time, for each package, the CPU 101 recognizes the number of times the package has been downloaded by the purchaser.

The menu includes a next page menu 902 for referring to another page (not shown), a download count menu 903 described later, and a TO
A Pn menu 904 is displayed.

When the purchaser clicks the mouse on input unit 302 to specify a menu on the homepage (step S804), distribution server 100
CPU 101 determines whether the specified menu is the download count menu 903 (step S80).
5). However, the specified menu is next page menu 9
If it is 02, the CPU 101 does not make the determination in step S805 and immediately causes the display unit 305 to display a predetermined page (not shown).

In step S805, if the designated menu is the download count menu 903 (step S805; YES), CPU 101 causes display unit 305 to display a command for inputting the download count. Here, the purchaser inputs the number of downloads via the input unit 302 (step S806).

Subsequently, when the purchaser operates the keyboard or the mouse to instruct the number of downloads inputted (step S807), the CPU 101
Searches for a package that satisfies the determined download count condition (step S808), specifies the sort page 910 as shown in FIG. 9B as a search result, and displays the sorted page 910 as a separate page from the homepage 900. 305 are displayed individually (step S812).

Here, the rearranged page 910 shown in FIG. 9B is, for example, "512" in step S806.
It is assumed that “2” has been input, and packages 911... With a download count exceeding 5122 times are displayed.

On the other hand, in step S805, if the specified menu is not the download count menu 903 (step S805; NO), the specified menu is the TOPn menu 904, so that the CPU 101 counts in descending order of download count. A command for inputting whether to display the top n packages is displayed on the display unit 305. Here, the purchaser inputs a desired order via the input unit 302 (step S80).
9).

Subsequently, when the purchaser operates the keyboard or the mouse to instruct the input order (step S810), the CPU 101 searches for a package satisfying the specified order based on the number of downloads. (Step S811), and the sorting page 920 as shown in FIG. 9C is individually displayed on the display unit 305 as a page different from the homepage 900 as a search result (Step S812).

The sort page 920 shown in FIG.
Assumes that "10" has been input in step S809, and the top ten packages 921 counted from the one with the largest number of downloads are displayed.

As described above, according to the program distribution system of the third embodiment, only packages satisfying the conditions of the number of downloads or the order specified by the purchaser are displayed on the server-side homepage. , Buyers always get the most useful programs.

Note that a plurality of packages displayed on the rearranged page in the receiving terminal 300 may be collectively downloaded. In this case, it is preferable to compress the packages displayed on the rearrangement page. When a plurality of packages are downloaded at once, the purchase fee may be set lower than when each package is downloaded separately.

[Fourth Embodiment] Next, a fourth embodiment will be described with reference to FIGS. The configuration of the program distribution system according to the fourth embodiment is substantially the same as the configuration of the program distribution system 1 according to the first embodiment, so that the illustration thereof is omitted and reference is made to the reference numerals shown in FIGS. I will explain while.

The operation of the program distribution system 1 according to the fourth embodiment will be described below with reference to the flowchart shown in FIG.

First, the purchaser accesses the home page on the server side (step S1001), and clicks a desired one of a plurality of packages (for example, the package 901 shown in FIG. 9) with the mouse of the input unit 302. Specify with. Then, a download page 1100 as shown in FIG. 11A is displayed (step S1002).

Here, the download page 1100 will be described with reference to FIG. 11A. This page stores a program file 1101 in which a main program of the educational program is stored, and a subprogram of the educational program. Subprogram file 110
2a, 1102b, 1102c, instruction files 1103a, 1103b storing instruction manuals for educational programs as text data, case files 1104a, 1104 for introducing the execution mode of the educational programs
b, 1104c, 1104d, 1104e, and a download menu 1105 for designating download of these files are displayed as icons.

Then, the download page 1100
In, the purchaser can freely select a combination of files to be downloaded (step S1003). More specifically, the combination can be selected by clicking the mouse of the input unit 302, and the selected file is displayed in a thick frame as shown in FIG. 11B.
That is, the download page 11 shown in FIG.
The display content of 10 assumes that a program file 1101, an instruction file 1103b, and a case file 1104a have been selected.

Then, the purchaser specifies a download menu 1105 by a click operation to download the selected file (step S1004). Due to this, the CPU 101 compresses the file selected by the purchaser and causes a compressed file menu 1106 as shown in FIG. 11C to be displayed on the download page 1120.

At this time, the CPU 101 determines whether a compressed file including a combination of files specified by the purchaser has already been stored in the storage unit 106 (step S1005). If there is no compressed file (step S
1005; NO), the CPU 101 compresses the file group specified by the purchaser (step S1006) and determines the file name of the compressed file (step S1007). The file name is automatically determined by the CPU 101 so as to associate a file included in the compressed file.

Then, the CPU 101 stores the generated compressed file in the storage unit 106 (step S100).
8). Next, the CPU 101 transmits a copy of the compressed file stored in the storage unit 106 to the receiving terminal 300 via the transmission control unit 104 to execute the download (step S1010).

On the other hand, in step S1005, if a compressed file composed of a combination of files designated by the purchaser has already been stored in storage unit 106 (step S1005; YES), CPU 101 executes download to execute the download. A copy of the existing compressed file is stored in the storage unit 106 via the transmission control unit 104 to the receiving terminal 300.
(Step S1010).

As described above, according to the program distribution system of the fourth embodiment, the program files, sub-program files,
Arbitrarily select the taking theory file and case file,
Now that the selected file is downloaded,
The purchaser can lower the purchase fee by purchasing (downloading) only necessary files.

Further, since only the sub-program file can be selected, the sub-program file can be downloaded as necessary, and the already downloaded educational program (main program) can be upgraded.

A list of case files and instruction files corresponding to a plurality of program files may be displayed. In this case, when download of only the listed case files and the like is designated, the CPU 101 selects a menu (not shown) for selecting whether or not to download a program file related to the case files and the like. ) Is preferably presented to the purchaser.

In this way, the purchaser downloads only the case files and the instruction files, and does not forget to download the program files related thereto. Also, a plurality of programs are previously stored in the receiving terminal 30.
Even if it is downloaded to 0 and it is specified to add only the case file or the instruction file, etc., it is possible to know which of the existing program files the case file corresponds to. . Furthermore, by presenting the selection menu to the server side, there is an effect that purchase of the program by the purchaser can be promoted.

[Fifth Embodiment] Next, a fifth embodiment will be described with reference to FIGS. The configuration of the program distribution system according to the fifth embodiment is substantially the same as the configuration of the program distribution system 1 according to the first embodiment, so that the illustration thereof is omitted and the reference numerals shown in FIGS. I will explain while.

The operation of the program distribution system 1 according to the fifth embodiment will be described below with reference to the flowchart shown in FIG.

First, the distribution server 100 creates a package in which the educational program, subprogram, instruction manual file, and casebook file created by the creator are packaged together (step S1200), and displays the package as an icon. It is attached to a homepage (step S1201).

At this time, the server or the creator can specify the desired sale amount of the package together with the iconized package (step S1202). Then, the designated desired sale price is displayed on the download page 1300, as shown in FIG. 13, in the form of a program file 1301, sub-program files 1302a, 1302b, 1302.
c, the instruction file 1303a, 1303b, the case file 1304a, 1304b, 1304c... and the download menu 1305 are presented as a desired sale amount menu 1306.

The purchaser browses the download page 1300, checks the desired sale amount menu 1306, selects the package to download, and designates the download menu 1305 by clicking the download menu 1305. (Step S
1203).

As a result, the selected package is downloaded to receiving terminal 300. At this time, the CPU 101 of the distribution server 100 counts the number of downloads corresponding to the downloaded package (step S1204), and calculates the relationship between the number of downloads and the desired sale price as a time series (step S120).
5).

Further, the CPU 101 calculates a demand-supply curve composed of a demand curve and a supply curve, as shown in FIG. 14, based on the calculated relationship between the number of downloads and the desired sale price (step S1206). According to this demand-supply curve, the intersection of the demand curve and the supply curve can be estimated as an appropriate price.

Here, the CPU 101 determines whether or not the selling price of the package should be set as an appropriate price (step S1207). When setting the selling price of the package as an appropriate price (step S1207; YE
S), the appropriate price is calculated from the intersection of the demand and supply curve (step S1208), and the calculated appropriate price is taken into consideration, and the current program download page 1300 is taken.
It is determined whether the amount presented as the desired sale amount menu 1306 is appropriate (step S1209).

If the desired sale price currently presented is not appropriate (step S1209; NO), the CPU 101
Notifies the creator of the program or the like that the desired sale price is to be changed (step S1210), and newly sets the appropriate price calculated in step S1208 (step S1211).

Here, the manner of setting a new appropriate price will be described with reference to FIGS. 13 (b) and 13 (c). For a package that is leveling off when the number of downloads is considered as a time series, FIG. As shown in FIG. 13B, the price presented as the desired sale price menu 1306 is reduced. On the other hand, for the package in which the number of downloads is remarkably increased, the desired sale price menu 1306 is displayed as shown in FIG. Increase the amount offered. C
The PU 101 adjusts the price of the package according to the above procedure, and presents the adjusted price on a homepage.

When the selling price is not set as the appropriate price in step S1207 (step S12)
07; NO), or after step S1211 is completed, the CPU 101 determines whether to delete the package in consideration of the increase rate of the number of downloads and the like (step S1212).

If it is determined that the package should not be deleted (step S1212; NO), the process returns to step S1203, and waits for download by the purchaser. On the other hand, if it is determined that the number of downloads is extremely small and the package should be deleted (step S1212; YES), the package is deleted from the homepage.

As described above, according to the program distribution system 1 in the fifth embodiment, the creator can freely specify the desired selling price of the educational program or the like, while setting the desired selling price to the educational program or the like. Since the price can be automatically changed to an appropriate price according to the number of downloads, the price of the final educational program or the like can be set to a value reflecting the evaluation of the purchaser.

[Sixth Embodiment] Next, a sixth embodiment will be described with reference to FIGS. Since the configuration of the program distribution system according to the sixth embodiment is substantially the same as that of the program distribution system 1 according to the first embodiment, the illustration thereof is omitted, and reference numerals shown in FIGS. It will be explained while doing so.

The operation of the program distribution system 1 according to the sixth embodiment will be described below with reference to the flowcharts shown in FIGS.

First, the purchaser accesses the home page on the server side (step S1500), and designates the icon corresponding to each of the plurality of packages by clicking on the icon desired to be purchased. As a result, FIG.
A download page 1800 as shown in (a) is displayed on the display unit 305 (step S1501).

[0136] The download page 1800 includes FIG.
As shown in (a), a program file 1801, subprogram files 1802a and 1802b, instruction files 1803a and 1803b, and a case file 1804
a, 1804b, 1804c, and 1804d are displayed as icons.

As shown in FIG. 18A, the program download page 1800 also displays a limit amount input menu 1806 for the purchaser to input a limit amount payable in advance. This limit amount input menu 1806 is in a state of accepting the input of the payment limit amount when specified by a click operation. On the other hand, if the limit amount input menu 1806 is not specified, the package can be downloaded by paying the price of the selected package by electronic payment.

[0138] Now, the purchaser enters a limit amount input menu 180 on the program download page 1800.
6 is specified by a click operation, and the maximum payment amount is input from a keyboard (not shown) of the input unit 302 (step S1502). The amount entered by the buyer is shown in FIG.
As shown in (a), the program download page 18
Displayed above 00. In FIG. 18A, it is assumed that "$ 4.00" has been input as the maximum payment amount.

When the purchaser completes the input of the payment limit, the CPU 101 determines whether or not the program file 1801 can be purchased with the input payment limit (step S1503). If the program file 1801 cannot be purchased with the input limit amount (step S1503; NO), the CPU 101 displays an error message (not shown) on the program download page 1800 (step S1504).

Next, the CPU 101 displays on the download page 1800 a menu (not shown) for allowing the purchaser to select whether to cancel the download of the program file 1801 or the like (step S1).
505). Here, if the purchaser has designated cancellation (step S1505; YES), the process returns to step S1501 again.

On the other hand, if the purchaser specifies not to cancel (step S1505; NO), the buyer can re-enter the payment limit in the limit input menu 1806 (step S1507). CPU10
1 detects the re-input of the payment limit by the purchaser, and makes the determination in step S1503 again.

If it is determined in step S1503 that the program file 1801 can be purchased with the limit entered by the purchaser (step S1503; YE
S), the CPU 101 executes the following processing. First, C
The PU 101 sets a parameter (hereinafter simply referred to as “balance”) for storing the balance of the payment limit amount in step S1.
At step 502 or at step S1507, the payment limit input by the purchaser is substituted (step S1508).

Next, the CPU 101 regards the program file 1801 as a candidate for download (step S1509), and subtracts the price of the program file 1801 from the value stored in the “balance”.
The reduced price is newly set as "balance" (step S1510).

Then, the CPU 101 uses the money amount stored in the "balance" to read the instruction manual files 1803a and 1803a.
3b (step S)
1511). That is, the CPU 101 determines whether or not the value of the newly set “balance” is larger than the price value of the instruction manual file 1803a.

When the value of “balance” is stored in the instruction manual file 180
3a... (Step S1511;
YES), CPU 101 substitutes 1 for parameter n (step S1600).

Here, n is a parameter (variable) for specifying each of the plurality of operation manual files 1803a. Hereinafter, when the “n-th instruction manual file” is described, when n is 1, it means the instruction manual file 1803a, and when n is 2, it is the instruction manual file 1803a.
3b. If n is 3 or more, there is no corresponding instruction manual file.

Now, the CPU 101 determines whether or not the n-th instruction manual file can be purchased with the amount stored in the “balance” (step S1601). If purchase is not possible (step S1601; NO), CPU 101
Increments the value of n by 1 (step S1602), and determines whether the n-th instruction manual file exists (step S1603). If the n-th instruction manual file exists (step S1603; YES), the CPU 101
Performs the determination of step S1601 again.

On the other hand, if it is determined in step S1601 that the n-th instruction manual file can be purchased (step S1601; YES), the CPU 101 regards the n-th instruction manual file as a candidate for downloading (step S1604). ), The price of the nth instruction manual file is subtracted from the value of “balance”, and the resulting value is newly stored in “balance” (step S160).
5).

After the processing of step S1605 is completed, or when the n-th instruction manual file does not exist in step S1603 (step S1603; N
O), the CPU 101 determines whether any one of the casebook files 1804a and 1804b can be purchased with the amount stored in the “balance” (step S1606). That is, the CPU 101 determines whether or not the value of the newly set “balance” is larger than the price value of the case collection file 1804a.

The value of “balance” is the casebook file 1804a
(Step S1606; YE)
S), the CPU 101 substitutes 1 for the parameter n (step S1607).

Here, n is a plurality of casebook files 18
04a... Are parameters (variables) that specify each of the elements 04a.
Hereinafter, when “n-th case collection file” is described, when n is 1, it means the case collection file 1804a, and n
Is 2, it means the case collection file 1804b, when n is 3, it means the case collection file 1804c, and when n is 4, it means the case collection file 1804d. When n is 5 or more, there is no corresponding case collection file.

The CPU 101 determines whether or not the n-th case collection file can be purchased with the amount stored in the “balance” (step S1608). If the purchase is not possible (step S1608; NO), the CPU 101
The value of n is incremented by 1 (step S1609), and it is determined whether or not the n-th case collection file exists (step S1).
610). If the n-th case collection file exists (step S1610; YES), the CPU 101 performs the determination in step S1608 again.

On the other hand, if it is determined in step S1608 that the n-th case collection file can be purchased (step S1).
608; YES), the CPU 101 regards the n-th case collection file as a candidate for download (step S1611), subtracts the price of the n-th case collection file from the value of “balance”, and subtracts the result. Is newly stored in the “balance” (step S1612).

After the processing in step S1612 is completed, or when the n-th case collection file does not exist in step S1610 (step S1610; NO),
Alternatively, if the value of “balance” is smaller than the price value of the casebook file 1804a at step S1606 (step S1606; NO), the CPU 101 uses the amount stored in the “balance” as the subprogram file 1802.
a to 1802c (step S)
1700). That is, the CPU 101 determines whether or not the value of the newly set “balance” is larger than the price value of the subprogram files 1802a.

When the value of “balance” is the subprogram file 1
802a ... (Step S170)
0; YES), the CPU 101 substitutes 1 for the parameter n (step S1701).

Here, n is a parameter (variable) specifying each of the plurality of subprogram files 1802a.
It is. Hereinafter, when “n-th subprogram file” is described, if n is 1, the subprogram file 1
802a, when n is 2, it means the subprogram file 1802b, and when n is 3,
It refers to the subprogram file 1802c. When n is 4 or more, there is no corresponding subprogram file.

Next, the CPU 101 determines whether or not the n-th sub-program file can be purchased with the amount stored in the “balance” (step S1702). If purchase is not possible (step S1702; NO), the CPU
101 increases the value of n by 1 (step S1703),
It is determined whether the n-th subprogram file exists (step S1704). If the n-th subprogram file exists (step S1704; YE
S), the CPU 101 performs the determination of step S1702 again.

On the other hand, if it is determined in step S1702 that the n-th sub-program file can be purchased (step S1702; YES), CPU 101 regards the n-th sub-program file as a candidate for download (step S1705). , The price of the n-th subprogram file is subtracted from the value of “balance”, and the resulting value is newly stored in “balance” (step S1706).

When the processing in step S1706 is completed,
Or, if none of the subprogram files 1802a ... can be purchased in step S1700 (step S1700).
1700; NO), or when the n-th subprogram file does not exist in step S1704 (step S1704; NO), the CPU 101 determines whether or not the money amount is stored in the “balance” (step S1707).

[0160] If the amount is stored in the "balance" (step S1707; YES), it is determined whether any one of the files displayed on the download page 1800 can be purchased with the stored amount. A determination is made (step S1708). If it can be purchased (step S17
08; YES), the CPU 101 returns to step S151.
It returns to the determination processing of 1.

On the other hand, if it is determined in step S1708 that no file can be purchased with the amount stored in the “balance” (step S1708; NO),
Alternatively, if the amount is not stored in the “balance” in step S1707 (step S1707; NO), the CP
U101 includes steps S1509, S1604,
The file captured as a candidate to be downloaded in step S1611 or step S1705 is displayed in a thick frame as shown in FIG. 18B (step S17).
09).

That is, in the download page 1810 shown in FIG.
01, the instruction manual file 1803, and the case collection files 1804b and 1804d are assumed to be automatically set by the CPU 101 as candidates to be downloaded.

Next, the CPU 101 proceeds to step S170.
In step S1710, a package in which the files displayed in bold frames in FIG. 9 are bundled is generated (step S1710), and the package is displayed on the download page 1810 as an icon 1807 as shown in FIG.

That is, the icon 1 shown in FIG.
807 includes a program file 1801, an instruction manual file 1803, and a case collection file 1804b, 1
804d are stored collectively.

Here, if the purchaser specifies the download menu 1805 by a click operation, the icon 1
The file stored in 807 is downloaded to the receiving terminal 300 via the transmission control unit 304 (step S1711).

As described above, according to the program distribution system in the sixth embodiment, the educational program to be downloaded is automatically determined within the range of the amount that can be paid in advance by the purchaser. Therefore, the purchaser can obtain a file corresponding to the payment limit without hesitation as to which file to purchase.

[Seventh Embodiment] Next, a seventh embodiment will be described. Since the configuration of the program distribution system according to the seventh embodiment is substantially the same as that of the program distribution system 1 according to the first embodiment, the illustration thereof is omitted and reference is made to the reference numerals shown in FIGS. I will explain while.

The operation of the program distribution system 1 according to the seventh embodiment will be described below with reference to the flowchart shown in FIG. As a premise, an application program for creating an educational program or the like that can be executed by the scientific calculator 400 is created by a company having another server (not shown) (hereinafter, referred to as “other company”). And

First, the server side makes a license contract with another company in advance (step S1900), and pays a predetermined price to freely download the application program from the server (not shown) of the other company to the distribution server 100. Make it available for download.

When the server downloads an application program from another company, the CPU 101 sets license information in the application program (step S1901). This license information is negotiated in a license contract between the server side and another company. Specifically, the number of times of communication between the distribution server 100 and the program providing server 200 and the restriction of a predetermined time required for the communication are limited. Information about Thus, if the limit is exceeded, the application program becomes invalid.

More specifically, the number of times of communication is twice when the application program is transmitted from the distribution server 100 to the program providing server 200 and when the application program is returned from the program providing server 200 to the distribution server 100. Is set. That is,
Only one round trip communication between the program providing server 200 and the distribution server 100 is allowed for sending and receiving the application program. Therefore, the server side is restricted from reusing the application program, and each time the application program is delivered to the creator, a fee is charged from another company. The predetermined time required for communication will be described later.

The creator accesses the server-side homepage in the program providing server 200 first.
Then, in order to download a desired application program posted on the homepage, the application program is designated by a click operation. Thus, the designated application program is downloaded by the CPU 201. In that process, the CPU 201 notifies the distribution server 100 via the transmission control unit 204 of a signal requesting distribution of the specified application program (step S1).
902).

In the distribution server 100, the CPU 101 that has detected the application program distribution request
Reply destination information such as a mail address corresponding to the distribution server 100 is added to the specified application program (step S1903). Thereby, the return destination of the application program is restricted only to the distribution server 100. Then, the CPU 101 transmits the application program to which the reply destination information is added to the program providing server 200.

In the program providing server 200, the CPU 20 detecting the reception of the application program
1 sets an environment for installing the application program and creating an educational program and the like. Here, the creator creates an educational program or the like in the set predetermined environment (step S1904).

Here, the license information is set by the CPU 101 in the application program downloaded by the program providing server 200 in step S1901. As described above, the license information defines a predetermined time in addition to the number of communications. Therefore, the elapsed time since installation of the application program (hereinafter simply referred to as “elapsed time”).
When the predetermined time specified in the license information elapses, the application program is automatically invalidated.

If the elapsed time is within the predetermined time defined in the license information (step S190)

Further, since the downloaded educational program is stored only temporarily in the receiving terminal, it is possible to prevent the purchaser from illegally copying the educational program.

[Twelfth Embodiment] Next, a twelfth embodiment will be described. Since the configuration of the program distribution system according to the twelfth embodiment is substantially the same as that of the program distribution system 1 according to the first embodiment, the illustration thereof is omitted and the reference numerals shown in FIGS. I will explain while.

The operation of the program distribution system 1 according to the twelfth embodiment will be described below with reference to the flowchart shown in FIG. As a premise, a creator or a purchaser (hereinafter, referred to as a “creator or the like”) is required to provide the distribution server 1 in advance.
It is assumed that an application program with a serial number (No.) is downloaded from 00 and an educational program or the like is created in a predetermined environment of the application program. In addition, a package in which the educational programs and the like and the application programs are packaged is a program providing terminal 200.
Alternatively, it is assumed that the receiving terminals 300 are prepared.

First, the creator or the like accesses the home page on the server side (step S2800) and browses the download page (step S2801). Although not shown, a menu for the creator or the like to specify the attachment of the package is displayed on the download page. Here, the creator or the like specifies the menu by clicking the mouse (step S2802).

Thus, the package created by the creator or the like is transmitted to distribution server 100. Upon detecting the reception of the package, the CPU 101 determines the serial number assigned to the application program included in the package. (Step S2803), it is determined whether the educational program or the like included in the package is appropriate (step S2804).

If it is determined that the educational program or the like included in the package is not appropriate (step S2804; N
O), that is, serial N
o. Is not added, or the serial No. is added. Is different from the one attached in advance on the server side, the CPU 101 causes the display unit 305 of the receiving terminal 300 to display that the package is improperly attached (step S2805).

Then, the CPU 101 deletes the programs, data, and the like included in the package transmitted to the distribution server (step S2806), performs a virus check (step S2807), and ends the process.

On the other hand, if it is determined in step S2804 that the educational program or the like included in the package is appropriate (step S2804; YES), that is, if the serial N
o. Is the same as the one attached in advance on the server side, the CPU 101 decompresses the package transmitted from the creator or the like (step S2808).

Then, the CPU 101 detects a keyword entered in a document file such as an instruction manual file included in a file generated as a result of the decompression (step S2809), and the detected keyword matches a predetermined keyword. (Step S)
2810). Here, the predetermined keyword is a keyword related to education. This keyword is set in advance by inputting at the input unit 102 of the distribution server 100.

If the document file is not appropriate (step S2810; NO), that is, if the document file does not include a predetermined keyword, the CPU
The display 101 displays the fact on the display unit 105.

Then, the administrator who has checked the display contents of the display unit 105 checks the contents of the corresponding document file (step S2811), and judges whether or not a package including the document file should be pasted on the homepage. . If it is determined that the package should not be attached (step S2812; NO), the data contained in the package is deleted (step S2813).
A virus check is performed (step S2814), and the process ends.

On the other hand, if the document file is appropriate (step S2810; YES), that is, if the document file contains a predetermined keyword, the CPU 101 displays H in order to present the package.
A TML file update process is executed, and the package is pasted on the homepage (step S2815). Thereby, the display content of the download page is updated (step S2816).

As described above, according to the program distribution system of the twelfth embodiment, the distribution server 1
Since 00 only accepts educational programs created in a predetermined application program, it is possible to unify the format of a file attached on a homepage.

Also, since only packages containing keywords related to education are pasted, packages that are not for educational purposes are not redundantly posted on the homepage on the server side.

Note that the keywords are not limited to those related to education, but may be related to general academic classification, more detailed technical terms, or other tasks.

[Thirteenth Embodiment] Next, a thirteenth embodiment will be described.
