  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, embodiment described below is embodiment at the time of applying this invention with respect to a shopping system.

[1. Overview of shopping system configuration and functions]
First, the configuration and functional overview of the shopping system S according to the present embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a diagram illustrating an example of a schematic configuration of a shopping system S according to the present embodiment.

  As shown in FIG. 1, the shopping system S includes a net super server 1, a plurality of user terminals 2, and a management terminal 3. The net super server 1 and each user terminal 2 can exchange data with each other via the network NW using, for example, TCP / IP as a communication protocol. The network NW is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station), a gateway, and the like. The net super server 1 and the management terminal 3 can transmit and receive data to and from each other via the network NL. The network NL is, for example, a LAN (Local Area Network).

  The net super server 1 (an example of an information providing apparatus in the present invention) is a server device that executes various processes related to a net super site that is a net super website. In response to a request from the user terminal 2, the net super server 1 transmits, for example, a web page of a net super site or performs processing related to product search or purchase.

  For example, a company that operates an existing supermarket chain or department store chain (hereinafter referred to as “net super company”) accepts orders from users via the network NW, and the ordered products are sent to the user's home etc. It is a service to deliver. In the online supermarket, the delivery date is defined according to the ordered time. When the ordered time is included in a predetermined early time of the day, the online super company delivers the ordered product on the same day. Therefore, users who can use the internet supermarket are limited to, for example, areas where stores belonging to internet supermarkets are located.

  The net super site may be operated by, for example, a company that mediates a plurality of net super companies and users. In the net super site, the user may be able to use net supers of a plurality of net super companies.

  A user terminal 2 (an example of a terminal device in the present invention) is a terminal device of a user who uses various websites. The user terminal 2 accesses a server device such as the net super server 1 based on an operation from the user. Thereby, the user terminal 2 receives and displays the Web page from the server device. As the user terminal 2, for example, a personal computer, a PDA (Personal Digital Assistant), a mobile information terminal such as a smartphone, a mobile phone, or the like is used.

  The management terminal 3 is a terminal device that is used by an administrator of an Internet super site to register, change, etc. information about products sold on the Internet super site.

  In the shopping system S having such a configuration, the net super server 1 transmits a product page corresponding to the product selected by the user to the user terminal 2. The product page is a Web page that displays product information that is information about the corresponding product on the Internet super site. The product information includes the price of the product. For example, the price of a product may be lower than the previous price due to price revision (price change) by an administrator of the net super site. In this case, the net super server 1 performs a process for displaying the revised price, which is the revised price, and the price before the revision on the product page so as not to confuse the revised price. .

  FIG. 2 is a screen display example of a product page before price revision according to the present embodiment. FIG. 4A is a screen display example of the unrevised price tag image 111 according to the present embodiment. As shown in FIG. 2, a product information area 100 or the like is displayed on the product page. The product information area 100 is an area where product information is actually displayed. The product information area includes a product name column 101 and a product detail column 102. In the product name column 101, product names are displayed. In the product detail column 102, detailed information on the product is displayed. Specifically, in the product detail column 102, a product image 103, a product description 104, an input button 105, a price tag 110, and the like are displayed. The product image 103 is a product image. A plurality of product images 103 may be displayed. The product description sentence 104 is a description text related to the product.

  When the input button 105 is selected by the user, the product whose information is displayed on the product page is put into the shopping cart, and the shopping cart page is displayed on the user terminal 2. The shopping cart in the present embodiment is a virtual container in which a product selected by the user as a candidate to be purchased is placed on the Internet super site. The shopping cart page is a Web page that displays a list of products that the user has put in the shopping cart. When the user selects a purchase procedure button on the shopping cart page, the user can perform a purchase procedure for the listed products.

  The price tag 110 is configured by adding a price character 112 to an unrevised price tag image 111. The price character is a number indicating the price of the product. The price character 112 (an example of information indicating the price of a transaction object whose price has not been changed in the present invention) indicates the price of a product for which the price has never been revised. The price in this state is called “initial price”. The price tag image is an image of a price tag. The unrevised price tag image 111 (an example of a third image in the present invention) is an image indicating that the price has never been revised. As shown in FIG. 4A, the unrevised price tag image 111 is an image of a rectangular price tag. In the price tag image, a “price” character is drawn in advance.

  In the present embodiment, the price character is attached to the price tag image means that the entire price character is displayed in the price tag image as shown in FIG. 2, or at least a part of the price character is the price tag image. It means that the price character is displayed in a state where it is overlaid on.

  FIG. 3A is a screen display example of the product information area 100 included in the product page that displays the latest revised price of the product that has undergone price revision according to the present embodiment. FIG. 4B is a screen display example of the price tag image 121 for the latest revised price according to the present embodiment. When the price is revised, as shown in FIG. 3A, the price tag 120 is displayed in the product information area 100 at the position where the price tag 110 was displayed.

  The price tag 120 is configured by adding a price character 122 to a price tag image 121 for the latest revised price. The price character 122 (information indicating the price after the change in the present invention) indicates the latest revised price. The latest price tag image 121 for the revised price (an example of the first image in the present invention) is an image indicating that the latest revised price is displayed. As shown in FIG. 4B, the latest price tag image 121 for the revised price is an image in which the lower right portion of the price tag is turned over (reference numeral 123 in FIG. 4B). Thus, the latest price tag image 121 for the revised price indicates that the user can remove the price tag 120. Since the appearance of the unrevised price tag image 111 is different from the appearance of the latest revised price tag image 121, the user can easily distinguish whether the price has been revised. Note that the difference in the appearance of the image is not limited to the difference in the shape of the image. For example, it is sufficient that at least one of the shape, pattern, color, or size of the image is different.

  FIG. 3B is a screen display example of the product information area 100 included in the product page that displays the initial price of the product for which the price revision has been performed according to the present embodiment. FIG. 4C is a screen display example of the price tag image for price before revision 131 according to the present embodiment.

  It is assumed that the user performs an operation for removing the price tag 120 shown in FIG. 3A (hereinafter referred to as “peeling operation”). Examples of the operation for removing the price tag 120 include an operation of dragging the latest price tag image 121 for the latest revised price using a mouse or a touch panel, and a selection operation such as clicking the price tag image 121 for the latest revised price. When the user performs an operation to remove the price tag 120, as shown in FIG. 3B, the price tag 120 is deleted from the product information area 100, and the price tag 130 is displayed at the position where the price tag 120 was displayed.

  The price tag 130 is configured by adding a price character 132 to a price tag image 131 for price before revision. The price character 132 (an example of information indicating the price before the change in the present invention) indicates the initial price of the product whose price has been revised. The price tag image 131 for price before revision (an example of the second image in the present invention) is an image indicating that the initial price of the product whose price has been revised is displayed. As shown in FIG. 4C, in the price tag image for price before revision 131, the pasted price tag is almost turned over (reference numeral 134 in FIG. 4C), and almost the entire price tag behind the price tag is displayed. It is an image in a visible state. Since the appearance of the price tag image 131 for the price before revision is different from the appearance of the price tag image 111 for the unrevised price and the price tag image 121 for the latest revised price, the user displays the initial price of the product whose price has been revised. Can be easily recognized.

  In addition, in order to confirm the price before the revision, by causing the user to perform the operation of removing the price tag 120, the user's interest is that the price of the product has been revised, that is, the price of the product has been reduced. Can be directed. Thereby, a user's willingness to purchase can be improved.

  When a preset time (for example, 1 second) elapses after the price tag 130 is displayed, the price tag 130 is deleted from the product information area 100 and the original price tag 120 is displayed again. That is, the current price is displayed. This is to prevent the user from erroneously recognizing that the price displayed on the price tag 130 is the current price by displaying the price tag 130 indefinitely.

  FIG. 3C is a screen display example of the product information area 100 included in the product page displaying the old revised price of the product for which the price revision according to this embodiment has been performed a plurality of times. FIG. 4D is a screen display example of the old revised price tag image 141 according to the present embodiment.

  Depending on the product, the price may be revised multiple times. In this case, when the user performs an operation of removing the price tag 120 shown in FIG. 3A, the price tag 120 is deleted from the product information area 100 and the price tag 120 is displayed as shown in FIG. 3C. The price tag 140 is displayed.

  The price tag 140 is configured by adding a price character 142 to the price tag image 141 for the old revised price. The price character 142 (an example of information indicating the next new price after the displayed price in the present invention) indicates the old revised price. The old revised price is a revised price registered between the initial price registration time and the latest revised price registration time. The old revised price tag image 141 (an example of the first image in the present invention) is an image indicating that an old revised price is displayed. As shown in FIG. 4D, the old price tag image 141 for the revised price is an image having a shape that combines the latest price tag image 121 for the revised price and the price tag image 131 for the price before revision. That is, the old price tag image 141 for the revised price is an image in which the pasted price tag is almost turned over (the portion 144 in FIG. 4D), and almost the entire price tag is visible behind it. In addition, it is an image in a state where the lower right portion of the back price tag is turned up (reference numeral 143 in FIG. 4D). Since the appearance of the old price tag image 141 for the revised price is different from the appearance of the price tag image 111 for the unrevised price, the price tag image 121 for the latest revised price, and the price tag image 131 for the price before revision, the user can see the old revised price displayed. Can be easily recognized.

  When the user performs an operation of removing the price tag 140, the price tag 140 is deleted from the product information area 100, and the price tag 130 is displayed, or another price tag 140 is displayed. Which price tag is displayed depends on the number of price revisions.

  The amount of peeling operation necessary to remove the price tag increases as the current processing load of the net super server 1 increases. When the network super server 1 receives a request from the user terminal 2, it needs to perform necessary processing and transmit a response each time. Therefore, if requests frequently occur, the processing load on the net super server 1 increases. On the other hand, while the user is performing an operation of removing the price tag, a request based on the user operation is not transmitted to the net super server 1 from the user terminal 2 used by the user. Therefore, the load on the net super server 1 is prevented from becoming excessive by adjusting the time required until the price tag is removed.

  Examples of the amount of peeling operation necessary to remove the price tag include the number of operations, operation time, operated distance, and the like. The processing load of the net super server 1 includes, for example, the number of HTTP (HyperText Transfer Protocol) requests received per unit time and the CPU (Central Processing Unit) usage rate. The number of HTTP requests received per unit time and the CPU usage rate are examples of load information in the present invention.

[2. Net Super Server Configuration]
Next, the configuration of the net super server 1 will be described with reference to FIG.

  FIG. 5 is a block diagram showing an example of a schematic configuration of the net super server 1 according to the present embodiment. As shown in FIG. 5, the net super server 1 includes a communication unit 11, a storage unit 12, an input / output interface 13, and a system control unit 14. The system control unit 14 and the input / output interface 13 are connected via a system bus 15.

  The communication unit 11 is connected to the network NW or the network NL, and controls the communication state with the user terminal 2, the management terminal 3, or the like.

  The storage unit 12 is configured by, for example, a hard disk drive. In the storage unit 12, a member information DB (database) 12a and a product information DB 12b are constructed.

  FIG. 6A is a diagram illustrating an example of contents registered in the member information DB 12a according to the present embodiment. In the member information DB 12a, member information regarding users who are registered as members of the Internet super site is registered. Specifically, the user ID, password, name, date of birth, sex, address, telephone number, e-mail address, etc., which are user identification information, are registered in the member information DB 12a in association with each user.

  FIG. 6B is a diagram illustrating an example of contents registered in the product information DB 12b according to the present embodiment. In the product information DB 12b, product information related to products sold on the Internet super site is registered. Specifically, in the product information DB 12b, product ID, product name, price related information, product image URL (Uniform Resource Locator), product description, etc., which are product identification information, are registered in association with each product. The

  FIG.6 (c) is a figure which shows an example of the content set to the price related information which concerns on this embodiment. The price related information is information related to the price of the product. Specifically, the number of revisions and the price are set in the price related information. The number of revisions is the number of times the price has been revised. When N is the number of revisions, N + 1 prices i (i = 0, 1, 2,... N) are set in the price related information. Price 0 is the initial price. Price N is the current price. If the number of revisions is 0, the price N is 0. That is, the initial price is the current price. When the number of revisions is one or more, the price N is the latest revision price.

  The storage unit 12 stores various data such as an HTML document, an XML (Extensible Markup Language) document, image data, text data, an electronic document, and the like that constitute a Web page of the online shopping mall. The HTML document is information that defines the operation of the user terminal 2 for displaying a Web page.

The storage unit 12 stores image data of price tag images 111, 121, 131, and 141. The storage unit 12 stores a template of the HTML document of the product page. The HTML document of the merchandise page (an example of the regulation information in the present invention) displays the price tag 120 when the price of the merchandise has been changed as the operation of the user terminal 2, and when the operation of peeling the price tag 120 is detected. Specifies that the price tag 120 is deleted from the screen and the price tag 130 or the price tag 140 is displayed. The product page template is an HTML document that is a framework of the HTML document of the product page. In this template, tags for displaying the price tags 110, 120, 130, or 140 are described. For example,
<table border = "0" background = "tagimage1.jpg"><tr><td></td></tr></table>
The tag is described. The background attribute of the table tag indicates the URL of the price tag image. In this background attribute, the URL of the unrevised price tag image 111 is set. The price character of the product is inserted between the td start tag and the td end tag.

[4-1. Net Super Server Operation]
FIG. 8 is a flowchart illustrating a processing example in the edited product information reception process of the system control unit 14 of the net super server 1 according to the present embodiment.

  The administrator of the net super site operates the management terminal 3 to newly register or change product information. At this time, when changing the product information, for example, the product ID of the product for which the product information is to be changed is input. Then, the management terminal 3 transmits a request to the net super server 1. The net super server 1 transmits a Web page for editing product information to the management terminal 3 in response to the request. At this time, if the net super server 1 determines that the item information is a change, the item information corresponding to the item ID included in the received request is acquired from the item information DB 12b. Then, the net super server 1 transmits a Web page displayed so that each piece of information included in the acquired product information can be edited.

  The management terminal 3 displays the received web page. The administrator inputs the product name, price, product image, product description, etc. of the new product, or changes the product name, price, product image, product description, etc. of the product already sold. Then, the management terminal 3 transmits the edited product information including the input or changed information to the net super server 1. The edited product information reception process is started when the net super server 1 receives the edited product information.

  First, the system control unit 14 determines whether or not the product information is newly registered (step S1). For example, if the received edited product information does not include the same product ID as any product ID registered in the product information DB 12b, the system control unit 14 determines that the registration is new ( Step S1: YES). In this case, the system control unit 14 sets the number of revisions to 0 (step S2). Next, the system control unit 14 registers the product information in the product information DB 12b (step S3). Specifically, the system control unit 14 generates a new product ID, and registers the product ID, the number of revisions, and the edited product information in the product information DB 12b as product information. At this time, the price included in the edited product information is registered as the initial price.

  Next, the system control unit 14 acquires a template of the HTML document of the product page from the storage unit 12 (Step S4). Next, the system control unit 14 inserts a setting sentence into the script included in the template so that the initial price included in the edited product information is set to the price 0 (step S5). Next, the system control unit 14 inserts each piece of information included in the registered product information at a predetermined position in the template to generate an HTML document of the product page (step S6). Thus, the system control unit 14 generates the HTML document of the product page displaying the price tag 110 as the second generation unit by executing the processes of steps S4 to S6.

  Next, the system control unit 14 stores the generated HTML document in the storage unit 12 in association with the URL of the product page corresponding to the product ID (step S7). When the process of step S7 is completed, the system control unit 14 ends the edited product information reception process.

  In step S1, if the system control unit 14 determines that it is a change registration of product information (step S1: NO), the system control unit 14 determines whether there has been a price change (step S8). The system control unit 14 determines whether or not the price of the product has been changed as a price determination unit by executing steps S1 and S8. The case of new registration of product information is also included when the price of the product has not been changed.

  For example, the system control unit 14 compares the price included in the received edited product information with the current price included in the product information to be changed registered in the product information DB 12b. If the compared prices match, the system control unit 14 determines that the price has not been changed (step S8: NO). In this case, the system control unit 14 rewrites the change target product information registered in the product information DB 12b with each piece of information included in the received edited product information (step S9).

  Next, the system control unit 14 acquires the HTML document of the product page corresponding to the product ID included in the edited product information from the storage unit 12 (step S10). Next, the system control unit 14 rewrites each information inserted in the acquired HTML document based on the edited product information to generate a new HTML document (step S11). Then, the system control unit 14 stores the generated HTML document in the storage unit 12 (step S7).

  In step S8, if the compared prices do not match, the system control unit 14 determines that the price has changed (step S8: YES). In this case, the system control unit 14 updates the number of revisions (step S12). Specifically, the system control unit 14 acquires the number of revisions from the change target product information registered in the product information DB 12b. Next, the system control unit 14 adds 1 to the number of revisions and updates the number of revisions.

  Next, the system control unit 14 additionally registers the price included in the edited product information as a revised price in the product information to be changed registered in the product information DB 12b (step S13). Next, the system control unit 14 rewrites the product information to be changed registered in the product information DB 12b with each information included in the edited product information and the updated number of revisions (step S14).

  Next, the system control unit 14 acquires the HTML document of the product page corresponding to the product ID included in the edited product information from the storage unit 12 (step S15). Next, the system control unit 14 rewrites the script setting statement included in the acquired HTML document so that the updated number of revisions is set as the number of revisions used in the script (step S16). Next, the system control unit 14 rewrites the URL set in the background attribute of the price tag display table tag included in the acquired HTML document to the URL of the latest price tag image 121 for the revised price (step S17). Next, the system control unit 14 inserts a setting sentence into the script included in the template so that the latest price included in the edited product information is set as the price N (step S18). Note that N at this time is the number of revisions after the update.

  Next, the system control unit 14 rewrites each information inserted in the acquired HTML document based on the edited product information to generate a new HTML document (step S11). Thus, the system control unit 14 generates the HTML document of the product page displaying the price tag 120 as the generation unit by executing the processes of steps S15 to S18 and S11.

  FIG. 9 is a flowchart illustrating a processing example in the request reception processing of the system control unit 14 of the net super server 1 according to the present embodiment. The request reception process is executed each time the net super server 1 receives an HTTP request (hereinafter referred to as “request”) from the user terminal 2.

  First, the system control unit 14 determines whether or not the received request is a request for a product page (step S31). At this time, if the system control unit 14 determines that the received request is a request for a product page (step S31: YES), the HTML document of the product page corresponding to the URL included in the request is stored from the storage unit 12. Obtain (step S32). Next, the system control unit 14 acquires the current number of received requests per unit time stored in the RAM 14c as load information acquisition means (step S33). The number of received requests per unit time is information that is updated in the process of step S37 described later. Next, the system control unit 14 determines the required number of operations based on the number of received requests per unit time (step S34). Specifically, the system control unit 14 increases the number of required operations as the number of requests received per unit time increases.

  Next, the system control unit 14 inserts a setting sentence into the script included in the acquired HTML document so that the determined required operation count is set as the required operation count used in the script (step S35). In this way, the system control unit 14 generates the HTML document of the product page as the generation unit, which increases the number of peeling operations necessary for removing the price tag 120 or the price tag 140 as the number of received requests per unit time increases.

  The system control unit 14 transmits the generated HTML document as a transmission unit to the user terminal 2 that is the transmission source of the request (step S36).

  Next, the system control unit 14 updates the number of received requests per unit time stored in the RAM 14c based on the reception of the request (step S37). When completing the process of step S37, the system control unit 14 ends the request reception process.

  In step S31, if the system control unit 14 determines that the received request is not a product page request (step S31: NO), the system control unit 14 determines whether the received request is a request for a price tag image (step S31). Step S38). At this time, if the system control unit 14 determines that the received request is a request for a price tag image (step S38: YES), the price tag image corresponding to the URL included in the request is the transmission source of the request. It transmits to the user terminal 2 (step S39). Next, the system control unit 14 updates the number of received requests per unit time (step S37), and ends the request reception process.

  On the other hand, when the system control unit 14 determines that the received request is not a request for a price tag image (step S38: NO), the system control unit 14 executes processing according to the received request (step S40). Next, the system control unit 14 updates the number of received requests per unit time (step S37), and ends the request reception process.

[4-2. Operation of user terminal 2]
FIG. 10 is a flowchart illustrating a processing example in the product page display process of the system control unit 27 of the user terminal 2 according to the present embodiment. The product page display process is started when the user terminal 2 transmits a request for a product page to the net super server 1.

  First, the system control unit 27 receives an HTML document of a product page corresponding to the transmitted request from the net super server 1 (step S51). Next, the system control unit 27 displays a product page on the screen of the display unit 23 based on the received HTML document (step S52).

  Next, the system control unit 27 loads the price tag image onto the product page. Specifically, the system control unit 27 transmits a request including the URL set in the background attribute of the table tag for price tag display included in the received HTML document to the net super server 1. Then, the system control unit 27 receives the price tag image from the net super server 1 (step S53). When the price tag image corresponding to the URL set in the background attribute is already stored in the storage unit 22 by the cache function provided by the browser, the system control unit 27 acquires the price tag image from the storage unit 22. To do. When receiving or acquiring the price tag image, the system control unit 27 displays the price tag image (step S54).

  Next, the system control unit 27 executes a script included in the received HTML document. The processing in steps S55 to S73 is processing described in this script. First, the system control unit 27 sets the number of revisions for the display price number i (step S55). Next, the system control unit 27 displays the price i on the price tag image by inserting a character indicating the price i between the price tag display td start tag and the td end tag included in the received HTML document. (Step S56). Thereby, when the revision number is 0, the price tag 110 is displayed in the product detail column 102 of the product page, and when the revision number is 1 or more, the price tag 120 is displayed in the product detail column 102 of the product page. Is displayed.

  Next, the system control unit 27 sets 0 as the number of operations for removing the price tag (step S57). Next, the system control unit 27 determines whether a drag operation of the displayed price tag image has been detected as a price tag peel operation (step S58). At this time, if the system control unit 27 determines that the drag operation of the price tag image has not been detected (step S58: NO), the system control unit 27 proceeds to step S71.

  On the other hand, when it is determined that the price tag image drag operation has been detected (step S58: YES), the system control unit 27 determines whether or not the display price number i is 0 (step S59). At this time, if the system control unit 27 determines that the display price number i is 0 (step S59: YES), the system control unit 27 proceeds to step S71.

  On the other hand, when the system control unit 27 determines that the display price number i is not 0 (step S59: NO), the price tag image drag operation is an effective operation. In this case, the system control unit 27 adds 1 to the number of peeling operations, and updates the number of peeling operations (step S60). Next, the system control unit 27 determines whether or not the number of peeling operations is equal to or greater than the required number of operations (step S61). At this time, if the system control unit 27 determines that the number of peeling operations is less than the required number of operations (step S61: NO), the system control unit 27 proceeds to step S71.

  On the other hand, if the system control unit 27 determines that the number of peeling operations is equal to or greater than the required number of operations (step S61: YES), the system control unit 27 switches display of price tags. First, the system control unit 27 updates the display price number i by subtracting 1 from the display price number i (step S62). Next, the system control unit 27 determines whether or not the display price number i is 0 (step S63). At this time, when the system control unit 27 determines that the display price number i is not 0 (step S63: NO), the system control unit 27 proceeds to step S64. This determination result indicates that there is a revised price that is older than the revised price that has been displayed so far, and therefore a new revised price should be displayed next to the revised price that has been displayed so far. Therefore, the system control unit 27 rewrites the URL set in the background attribute of the price tag display table tag included in the received HTML document to the URL of the old price tag image 141 for the revised price (step S64). On the other hand, if the system control unit 27 determines that the display price number i is 0 (step S63: YES), the system control unit 27 proceeds to step S65. This determination result indicates that there is no revised price older than the revised price that has been displayed so far, and therefore the initial price should be displayed. Therefore, the system control unit 27 rewrites the URL set in the background attribute of the price tag display table tag included in the received HTML document to the URL of the price tag image for price before revision 131 (step S65).

  After completing the process of step S64 or S65, the system control unit 27 loads the price tag image associated with the URL rewriting. Specifically, the system control unit 27 transmits a request including a URL newly set in the background attribute of the table tag to the net super server 1. Then, the system control unit 27 receives the price tag image from the net super server 1 (step S66). When the price tag image corresponding to the URL set in the background attribute is already stored in the storage unit 22, the system control unit 27 acquires the price tag image from the storage unit 22.

  Next, the system control unit 27 deletes the price tag image displayed in the product detail field 102 and displays the received or acquired price tag image (step S67). Next, the system control unit 27 rewrites the price character set between the price tag display td start tag and the td end tag included in the received HTML document into a character indicating the price i, and the price tag image. The price i is displayed above (step S68).

  Next, the system control unit 27 determines whether or not the display price number i is 0 (step S69). That is, the system control unit 27 determines whether or not the currently displayed price is the initial price before the price revision. At this time, when it is determined that the display price number i is 0 (step S69: YES), the system control unit 27 sets a timer for switching the display of the price tag (step S70). Specifically, the system control unit 27 sets timer information indicating the time required from when the price tag 130 is displayed until the original price tag 120 is displayed, for example, in units of milliseconds. The set timer information is decremented by 1 every 1 millisecond. When the process of step S70 is completed or when it is determined that the display price number i is not 0 (step S69: NO), the system control unit 27 proceeds to step S57.

  In step S71, the system control unit 27 determines whether or not a set time has elapsed since the price tag 130 was displayed. Specifically, the system control unit 27 determines whether or not the set timer information indicates 0. At this time, if the system control unit 27 determines that the set time has elapsed (step S71: YES), it switches the display of the price tag. First, the system control unit 27 sets the number of revisions for the display price number i (step S72). Next, the system control unit 27 rewrites the URL set in the background attribute of the price tag display table tag included in the received HTML document to the URL of the latest revised price price tag image 121 (step S73). Next, the system control unit 27 loads the price tag image associated with the URL rewriting, and changes the price character set between the price tag display td start tag and the td end tag to the character indicating the price i. Rewriting is performed (steps S66 to S68).

  In step S71, when the system control unit 27 determines that the set time has not elapsed (step S71: NO), the system control unit 27 determines whether an operation for requesting a web page has been detected (step S74). ). The operation for requesting a Web page includes, for example, an operation for selecting a hyperlink and an operation for selecting the input button 105. If the system control unit 27 determines that an operation for requesting a web page has not been detected (step S74: NO), the system control unit 27 proceeds to step S58. On the other hand, if the system control unit 27 determines that an operation for requesting a web page has been detected (step S74: YES), it ends the product page display process and transmits a web page request.

[5. Modified example]
When the display space of the product detail column 102 on the product page has room, even if the price is revised, the price before the revision and the price after the revision may be displayed in the product detail column 102 at the same time. In this case, except for the display of the price of the product, information that takes a display space in the product detail column 102 is mainly the product image 103 and the product description 104. Therefore, the display mode of the price is determined based on the display area of the product image and the product description as product information. The product image and the product description are examples of transaction target information in the present invention.

  When the total display area of the product image and the product description is equal to or greater than a preset threshold, the system control unit 14 of the net super server 1 displays a product page (hereinafter, “price”) in a manner as shown in FIG. , Referred to as “single price display product page”). On the other hand, when the total display area of the product image and the product description is less than the threshold, the system control unit 14 displays a product page (hereinafter referred to as a “multiple price display product page”) that simultaneously displays the prices before and after the revision. Generate an HTML document.

  When the prices before and after the revision are displayed at the same time, the price after the revision is the latest revised price. On the other hand, the price before the revision may be, for example, an initial price or a new price next to the latest revised price. The prices before and after the revision are displayed so that the user can distinguish them. For example, the price tag 110 and the price tag 120 may be displayed at the same time. Also, the color, size, etc. may be different between the price before the revision and the price after the revision. In addition, the price before the revision may be displayed in parentheses or in a state where it is canceled by a strikethrough.

  The threshold may be set in advance by the administrator of the net super site. Further, a predetermined ratio of the display area of the product detail field 102 may be set as a threshold value. The ratio in this case may be set in advance by the administrator.

  FIG. 11 is a flowchart showing a processing example in the edited product information reception process of the system control unit 14 of the net super server 1 according to the modification of the present embodiment. In FIG. 11, steps similar to those in FIG. 8 are given the same step numbers.

  The processing in steps S1 to S14 is the same as the processing described in FIG. When the process of step S14 is completed, the system control unit 14 calculates the display area of the product image and the product description as an area information acquisition unit (step S21). Specifically, the system control unit 14 acquires the number of vertical and horizontal pixels of the product image from the header portion of the product image. Next, the system control unit 14 calculates the area of the product image by multiplying the acquired number of vertical and horizontal pixels. In addition, the system control unit 14 acquires the number of characters of the product description. Next, the system control unit 14 calculates a display area corresponding to the acquired number of characters in units of pixels. Then, the system control unit 14 calculates the total value of the display area of the product image and the display area of the product description.

  Next, the system control unit 14 determines, as an area determination unit, whether or not the calculated total value of the display areas is greater than or equal to a threshold (step S22). At this time, if the system control unit 14 determines that the calculated total value is less than the threshold (step S22: NO), the system control unit 14 proceeds to step S23. This determination result indicates that there is room in the display space of the product detail field 102 on the product page. Therefore, the system control unit 14 generates a multi-price display product page that simultaneously displays the prices before and after the revision in the product detail column 102. Therefore, the system control unit 14 acquires a template of the HTML document of the multi-price display product page from the storage unit 12 (step S23). In this template, for example, a price display tag before the revision and a price display tag after the revision are described. Also, this template does not describe a script for switching the display of price tags.

  Next, the system control unit 14 inserts the prices before and after the revision between the start tag and the end tag for price display before and after the revision of the acquired template (step S24). Next, the system control unit 14 inserts each piece of information included in the edited product information at a predetermined position in the template to generate an HTML document of a multi-price display product page (step S25). Thus, the system control unit 14 generates the HTML document of the product page that simultaneously displays the prices before and after the revision as the third generation unit by executing the processes of steps S23 to S25. Next, the system control unit 14 proceeds to step S7.

  In step S22, when the system control unit 14 determines that the calculated total value is greater than or equal to the threshold (step S22: YES), the system control unit 14 proceeds to step S26. This determination result indicates that there is no room in the display space of the product detail field 102 on the product page. Therefore, the system control unit 14 generates a single price display product page for displaying only one of the prices before and after the revision in the product detail column 102. Therefore, the system control unit 14 acquires a template of the HTML document of the single price display product page from the storage unit 12 (step S26). Next, the system control unit 14 performs the processes of steps S16 and S17.

  Next, the system control unit 14 inserts a setting sentence into the script included in the template so that the latest price is set from the initial price to the price 0 to the price N (step S27). Next, the system control unit 14 proceeds to step S25.

  Even if there is no change in price, the product image and the product description may be changed. Therefore, the system control unit 14 may execute the processes of steps S21 to S26, S16, S17, and S27 even when the price has not been changed and the number of revisions is one or more.

  Further, the system control unit 14 may make the determination based only on either the display area of the product image or the display area of the product description. Further, when information other than the product image and the product image is displayed as the product information in the product detail field 102, the system control unit 14 may make a determination based on the display area of the displayed information. good.

  The processing content when the user terminal 2 receives the HTML document of the single price display product page is the same as the processing shown in FIG. On the other hand, the processing content when the HTML document of the multi-price display product page is received is the same as the known processing content for displaying the Web page based on the description of the HTML document.

  As described above, the system control unit 14 of the net super server 1 displays and displays the latest price tag image 121 for the latest revised price with the price character 122 indicating the price after the change of the product whose price has been changed. When an operation for removing the latest price tag image 121 for the latest revised price is detected, an HTML document of a product page that defines that the price tag image 121 for the latest revised price is deleted from the screen and the price before the change is displayed is generated. The generated HTML document of the product page is transmitted to the user terminal 2.

  Therefore, the user can recognize that the changed price is displayed. In addition, since the prices before and after the change are not displayed at the same time, the prices before and after the change can be displayed without taking a space for displaying a plurality of prices.

  In addition, the system control unit 14 acquires the number of requests received per unit time, acquires the number of operations for which the displayed price tag image 121 for the latest revised price is peeled off, and the acquired number of operations is the required number of operations. In such a case, an HTML document of a product page that specifies that the price tag image 121 for the latest revised price is deleted from the screen and the price before the change is displayed is generated, and the number of received requests per unit time increases. Increase the number of required operations.

  Therefore, it is possible to prevent the processing load on the net super server 1 from becoming excessive.

  Further, the system control unit 14 deletes the price before the change from the screen and displays the price tag image 121 for the latest revised price again when a preset time has elapsed since the price before the change was displayed. An HTML document of a product page that prescribes is generated.

  Therefore, it is possible to prevent the user from erroneously recognizing that the displayed price is the current price by displaying the price before the change indefinitely.

  Further, when the system control unit 14 displays the price before the change, the price before the revision that is different in appearance from the price tag image 121 for the latest revised price is displayed as the price letter 132 indicating the price before the change. An HTML document of a product page that defines that the price tag image 131 is displayed is generated.

  Therefore, the user can clearly recognize which price is displayed between the price before the change and the price after the change.

  In addition, when the system control unit 14 determines whether or not the price of the product has been changed, and when it is determined that the price of the product has not been changed, as an image to which information indicating the price of the product is attached, When an HTML document of a product page that specifies that the price tag image 111 for unrevised price, which is different in appearance from the latest price tag image 121 for price, is displayed and it is determined that the price of the product has been changed, the latest An HTML document of a product page for displaying the price tag image for revised price 121 is generated.

  Therefore, it is possible to make the user recognize whether the price of a product whose price has not been changed is displayed, or whether the price tag image 121 for the latest revised price is removed and the price before the change is displayed. .

  Further, the system control unit 14 displays the latest price tag image 121 for the latest revised price with the information indicating the latest price of the product whose price has been changed a plurality of times, and detects the peeling operation of the price tag image 121 for the latest revised price. If the price tag image 121 for the latest revised price is deleted from the screen and the newest price next to the displayed price is not the oldest price, the newest price next to the displayed price is set. An HTML document of a product page that defines that the price tag image for old revised price 141 with the information to be displayed is displayed is generated.

  Therefore, the user can confirm how the price has been changed by performing the operation of peeling the price tags one after another, and can improve the willingness to purchase the product.

  Further, the system control unit 14 calculates the display area of the product image and the product description displayed together with the price based on the HTML document of the product page, and determines whether or not the calculated display area is equal to or larger than the threshold value. When it is determined that the display area is not equal to or greater than the threshold, an HTML document for a multi-price display product page is generated, and when it is determined that the display area is equal to or greater than the threshold, Is generated.

  Therefore, the display space can be saved when the display space is not sufficient.

  Note that information on the price to be displayed on the price tag may be acquired from the net super server 1 each time the user terminal 2 switches the display of the price tag. For example, in step S68 shown in FIG. 10, the user terminal 2 creates a script in the HTML document of the product page so as to send an asynchronous request including the product ID corresponding to the product page and the display price number i to the net super server 1. Is described. The net super server 1 that has received the asynchronous request acquires the price corresponding to the display price number i included in the request from the product information corresponding to the product ID included in the request. Then, the net super server 1 transmits a response including the acquired price to the user terminal 2.

  In the above embodiment, the net super server 1 determines the amount of operation necessary to remove the price tag when transmitting the HTML document of the product page to the user terminal 2. However, the net super server 1 may determine the amount of operation necessary to remove the price tag when the user performs a peeling operation while the product page is displayed on the user terminal 2, for example. For example, an HTML document of a product page is transmitted so that an asynchronous request for inquiring an operation amount necessary for removing a price tag is transmitted from the user terminal 2 to the net super server 1 when the user performs the first peeling operation. Script is described in The net super server 1 that has received the asynchronous request from the user terminal 2 determines an operation amount necessary for removing the price tag based on the current processing load of the net super server 1, and sends a response including the determined operation amount to the user. Transmit to terminal 2. Based on the received operation amount, the user terminal 2 determines whether to switch the display of the price tag according to the detection of the peeling operation.

  In addition, the net super server 1 generates a price tag image in which price characters are drawn in advance, and generates an HTML document of the product page so that the price tag image in which price characters are drawn is displayed on the product page. You may do it. In this case, the user terminal 2 acquires the price tag image corresponding to the product ID corresponding to the product page and the current display price number i from the net super server 1 and displays the price tag image on which the price is described. Is displayed on the product page.

  Further, when the number of operations required for removing the price tag is two or more, for example, a price tag that gradually turns up according to the user's peeling operation may be displayed in the product detail column 102. In this case, the administrator stores various price tag images with the price tags turned up in the storage unit 12 of the net super server 1. For example, when the number of peeling operations is updated in step S60, the user terminal 2 loads a price tag image corresponding to the number of peeling operations. Here, when the user terminal 2 first detects a peeling operation, the user terminal 2 may acquire all price tag images necessary for display from the net super server 1 in advance.

  In addition, when the latest revision price is displayed on the product page when the number of revisions of the price is two times or more, the net super server 1 is in a state in which the lower right part is turned up as the price tag image 121 for the latest revision price. An HTML document of a product page may be generated so that an image with a plurality of price tags overlapped is displayed. Thereby, the user can easily recognize that the price revision has been performed a plurality of times.

  In addition, the net super server 1 displays the latest price tag image 121 for the revised price with the price character indicating the revised price only when the price becomes lower than the previous price due to the price revision. Alternatively, an HTML document of a product page may be generated. On the other hand, when the price becomes higher than the previous price, the net super server 1 displays the price tag image 111 for the unrevised price with the price character indicating the revised price displayed. An HTML document of a product page may be generated so that this unrevised price tag image 111 cannot be removed.

  When the administrator changes the price of the product, the net super server 1 deletes the previous price from the product information and registers the new price as the initial price in the product information DB 12b. May be. That is, the net super server 1 may perform a process for resetting the price display.

  Further, the net super server 1 may generate an HTML document of the product page so that the price tag 110 is displayed when an operation of removing the price tag 120 is performed regardless of the number of price revisions.

  In addition, for example, when a discount period (time zone, date, day of the week, etc.) is determined in advance, such as a time sale, the initial price as a normal price and the revised price as a discount price are used as price related information. And may be set. In this case, for example, the discount price is set in association with information indicating a period during which the discount price is applied. When the time at which the request for the product page is received is not included in the period for which the discount price is applied, the net super server 1 displays the price tag 110 for displaying the normal price so that the price tag 110 for displaying the normal price is displayed. Generate a document. In addition, when the time at which the request for the product page is received is included in the period in which the discount price is applied, the net super server 1 displays the price tag 120 for displaying the discount price. HTML document is generated. Alternatively, the net super server 1 generates an HTML document for the product page so that the user terminal 2 controls whether to display the price tag 110 or the price tag 120 according to the time when the HTML document for the product page is received. May be.

  Further, the regulation information in the present invention may be applied to information other than an HTML document, such as an XML document.
