Description

  The present invention relates to a network auction system that implements an auction using a network system, and relates to a system that combines a scratch auction belonging to a so-called Dutch auction in which the selling price of an item for sale decreases stepwise.

  In the auction, there is a method called Dutch auction (Dutch type auction in Patent Document 1) in which the bid price decreases, contrary to the method in which the bid price increases.

  On the other hand, recently, a penny auction, which requires a fee each time a bid is placed, has become widespread as an online auction. This penny auction is usually characterized in that the starting price is low and the unit of one bid is also low. However, even if the bid is successful, the bid participant may pay a significant fee for multiple bids. Furthermore, even if the final bid cannot be made, a fee must be paid for each bid. Using the characteristics of the penny auction method, some penny auction operators will participate in bidding and raise the winning bid, and this operator will eventually make a successful bid. Has occurred.

  In order to correct such a weakness of the penny auction, a scratch auction in which a Dutch auction is combined with a penny auction has become widespread. Specifically, the starting price is the highest price, and the price decreases with each bid, but the current lowest bid price (latest bid price) is hidden and is not known to bidders. In order to know the minimum bid price, you must pay a fee to view it.

JP 2003-281410 A

  However, in this scratch auction, even if you pay a fee and view the latest bid price (that is, the lowest bid price), the price may not have dropped sufficiently. Motivation to browse is less likely to occur. In particular, if the latest bid price is higher than the auction participant's allowable price near the end of the auction, few auction participants will browse the site repeatedly to confirm that the latest bid price has fallen to the allowable price. Many auction participants give up bidding more than that.

  Therefore, according to the present invention, in a so-called scratch auction, when the end of the auction is about to end, the auction participant can follow the bid price that is decreasing every moment in real time, and can increase the motivation of the auction participant to bid. An object is to provide an auction providing server.

  In order to achieve the above object, an auction providing server according to the present invention is a server that is connected to a plurality of client devices via a network and provides an auction, and includes information related to an auction target product and an initial product price. A storage device that stores information about a certain starting price and the latest bid price and the latest bidder during the auction, and a predetermined time determination that determines whether or not a predetermined time has elapsed from the auction end time First information including information related to the target product and a bid instruction display so as to accept a bid for the target product when the determination unit determines that the time before the predetermined time is not a predetermined time before the auction end time. Are displayed on the client devices participating in the auction via the network. First bid waiting processing means for waiting for a bid, and determining whether or not a bid instruction display on the first bid screen is selected from one client device via the network, When the bid determination means and the first bid determination means determine that the bid instruction display on the first bidding screen is selected, if the bid is the first bid after the start of the auction, a predetermined amount is subtracted from the start price. The stored price is stored in the storage device as the latest bid price, and in a case other than the first bid, the price obtained by subtracting the predetermined amount from the latest bid price stored in the storage device is stored in the storage device as the latest bid price. The purchase screen including the latest bid price and purchase instruction display is displayed on the one client device through the network for a predetermined display period, and the one client device is displayed. Bid processing means for displaying a standby screen including a display indicating that a bid is not accepted on a client device other than the client device for a first predetermined period via the network and executing a bid process And determining whether or not the purchase instruction display is selected from the one client device via the network, and when the purchase determination means determines that the purchase instruction display is selected, The other client device displays an auction end notification screen including that the target product has been purchased and the auction has ended via the network, and the target product has been purchased from the one client device. The first buying and selling processing means for executing the accompanying buying and selling process and the predetermined time-predetermined judging means are configured to execute the first trading from the auction end time If a time before the predetermined time is determined, a second bidding screen including the remaining time until the end of the auction, information on the latest bidder client device, and the latest bid price is sent via the network. Whether or not a bid instruction display on the second bidding screen is selected from the second bid waiting processing means for displaying on the client device participating in the auction and waiting for the bid, and the one client device via the network. When the second bid determination means and the second bid determination means determine that the bid instruction display on the second bid screen is selected, the latest bid stored in the storage device is determined. As a result of subtracting the predetermined amount from the price, when the latest bid price becomes 0 or less, the target product is purchased free of charge from the one client device. When the second buying and selling processing means for executing the buying and selling process associated therewith and the second bidding determining means determine that the bid instruction display on the second bidding screen is selected, the storage device stores As a result of subtracting the predetermined amount from the stored latest bid price, if the latest bid price is larger than 0, the second predetermined period is set after the bid instruction display on the second bidding screen is selected. If the bidding instruction display on the second bidding screen is not selected from another client device within the lapse of time, the buying and selling process associated with the purchase of the target product from the one client device is executed. And buying and selling processing means.

  According to the present invention, when the time before the predetermined time from the auction end time is reached, the remaining time until the end of the auction, the information regarding the latest bidder client device (the last bidder client device), and the latest bid price are obtained. Since the second bidding screen is displayed on the client device participating in the auction via the network and waits for the bidding, all the auction participants can view the bid price near the end of the auction. Therefore, there is no need to pay a fee and view the current bid price as in the conventional scratch auction, so the auction participants can follow the ever-decreasing bid price in real time and motivate bidding. Rise. In addition, since the state in which the current bid price is decreasing is viewed by all auction participants in this way, the auction is compared to the case where the latest bid price is hidden as in the conventional scratch auction. Increases transparency.

  According to a preferred embodiment of the present invention, the storage device includes a memory device provided in the server and a database connected to the server, and the database includes the information related to the target product of the auction and the first product. The starting price, which is a price, is stored, and the memory device stores information on the latest bid price and the latest bidder at any time during an auction to store an auction history, and after the auction ends The auction history is moved to the database server.

  According to this auction server, when a predetermined time before the auction end time, the second bidding screen including the remaining time until the end of the auction, information on the latest bidder client device, and the latest bid price, Since it is displayed on the client device participating in the auction via the network, the auction participant can know the latest bid price without paying a fee. As a result, the number of client devices for bidding becomes enormous and the load on the server may increase. On the other hand, according to this embodiment, in addition to the database connected to the server, a memory device provided in the server, which has a storage capacity smaller than the database but a transfer rate faster than the database, is used. Thus, the history during the auction can be temporarily stored. For this reason, since the processing capacity of the server is increased as compared with the case where only the database is used, even if the load on the server increases, the server can operate without any problem. Further, the memory device stores the auction of the target product as a group of data units. For this reason, movement to and from the database server is performed for each data unit.

  According to a further preferred embodiment of the present invention, the first buy / sell processing means and the third buy / sell processing means are predetermined after the purchase instruction display or the bid instruction display is selected from the one client device. If the settlement process is not performed during the waiting period, the bid is canceled.

  According to the auction providing server of the present invention, the auction participants can follow the ever-decreasing bid price in real time, and the motivation for bidding is increased, leading to an increase in the number of auction participants.

1 is a configuration diagram of a system including a server according to an embodiment of the present invention. It is a flowchart which shows the process of the server of FIG. (A)-(d) is a figure which shows the screen displayed on the client apparatus in the system of FIG.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the configuration of an auction system according to this embodiment. This system 1 includes an auction providing web server 2, a database server 3 connected to the web server 2 directly or via a network, and a memory device 4 directly installed inside or outside the web server 2.

  The web server 2 is connected to the Internet 6 and provides a web page accessed from a large number of client devices 8 (8A, 8B, 8C,...) Connected to the Internet 6. The client device 8 corresponds to a personal computer, a mobile phone, a portable information terminal, and the like, and any terminal device provided with a communication function that can be connected to the Internet 6 is applicable.

  The web page provided by the web server 2 is for providing an auction, and this auction is operated by a person who sells one or more target products.

  The web server 2 includes constituent elements to be described later, that is, a predetermined time previous determination unit 21, a first bid waiting processing unit 23, a first bid determination unit 25, a bidding processing unit 27, a purchase determination unit 29, a first Trading means 91, second bid waiting processing means 93, second bid determination means 95, second buying and selling processing means 97, and third buying and selling processing means 99. Each of these components executes an auction process for one target product A. Since auctions for a plurality of target products proceed in parallel, a plurality of the same components can function simultaneously.

  The storage device of the auction system includes a database server 3 and a memory device 4. The database server 3 stores information related to the target product of the auction and the start price that is the first product price. The memory device 4 includes an auction information storage unit 41 that stores information necessary during an auction for each auction of the target product, and the auction information storage unit 41 has the same number of auctions being held in the web server 2, that is, There are as many items as there are target products. The auction history is stored in the auction information storage unit 41 at any time during the auction by storing information about the latest bid price and the latest bidder, and after the auction is completed, the auction history is stored in the database. Moved to server 3.

  Predetermined time determination means 21 determines whether a time before a predetermined time (for example, 5 minutes) has elapsed from the auction end time.

  When the first bid waiting processing means 23 determines that the predetermined time ago determination means 21 has not yet reached the time before the predetermined time (5 minutes) from the auction end time, the target commodity (in this embodiment, the target commodity A first bid screen including information related to the target product A and a bid instruction display is displayed on the client device 8 participating in the auction via the network 6 so that the bid of A) is accepted, and the bid is awaited. Is.

  The first bid determination means 25 determines whether or not the bid instruction display on the first bid screen is selected from one client device 8 (for example, the client device 8A) via the network 6.

  When the first bidding determining unit 25 determines that the bid instruction display on the first bidding screen is selected, the in-bid processing unit 27 subtracts a predetermined amount from the starting price if it is the first bid after the start of the auction. The stored price is stored in the memory device 4 as the latest bid price, and in a case other than the first bid, the price obtained by subtracting a predetermined amount from the latest bid price stored in the memory device 4 is stored in the memory device 4 as the latest bid price. Then, one client device 8A displays a purchase screen including the latest bid price and purchase instruction display over a predetermined display period via the network 6, and other client devices 8B other than the one client device 8A. , 8C,..., A bid screen is displayed by displaying a standby screen including a display not accepting bids for a first predetermined period via the network 6. Than is.

  The purchase determination means 29 determines whether or not a purchase instruction display is selected from one client apparatus 8A via the network 6.

  If the purchase determination means 29 determines that the purchase instruction display has been selected, the first trading processing means 91 informs the other client devices 8B, 8C,... That the target product A has been purchased and the auction has ended. The auction end notification screen is displayed via the network 6 and the sale processing associated with the purchase of the target product A from one client device 8A is executed.

  When the second bidding standby processing means 93 determines that the predetermined time-before-determining means 21 is the time before the first predetermined time (5 minutes) from the auction end time, the remaining time until the end of the auction, the latest The second bidding screen including the information related to the client device 8 that has made a bid and the latest bid price is displayed on the client device 8 participating in the auction via the network 6 and waits for a bid.

  The second bid determination means 95 determines whether or not the bid instruction display on the second bid screen is selected from one client apparatus 8A via the network 6.

  When the second bid determination unit 95 determines that the bid instruction display on the second bidding screen is selected, the second sale processing unit 97 subtracts a predetermined amount from the latest bid price stored in the memory device 4. As a result, when the latest bid price becomes 0 or less, the sale processing is executed in accordance with the purchase of the target product A from one client device 8A free of charge.

  When the second bid determination unit 95 determines that the bid instruction display on the second bidding screen is selected, the third trade processing unit 99 determines a predetermined value from the latest bid price stored in the memory device 4. If the latest bid price is greater than 0 as a result of subtracting the amount of money, the other client devices 8B, 8C, 8B, 8C,. If the bid instruction display on the second bidding screen is not selected from..., The sale processing associated with the purchase of the target product A from one client device 8A is executed.

  The first buying and selling processing means 91 and the third buying and selling processing means 99 also do not perform a settlement process during a predetermined waiting period after the purchase instruction display or the bid instruction display is selected from the one client device 8A. Cancel the bid.

  Next, the processing flow of this system will be described using the flowchart shown in FIG. 2 and the screens displayed on the client devices shown in FIGS.

[Step S1]
When the server 2 in FIG. 1 starts accepting bids for the target product A, the remaining time until the end of the auction is counted using a timer (not shown) in the server 2. Specifically, if the bid acceptance period (auction period) of the target product A is, for example, 3 days (72 hours), the remaining time at the start of the auction is 72 hours, and the remaining time is reduced as time elapses. Then, the determination means 21 before the predetermined time of the server 2 determines whether or not the time before the predetermined time has come from the end time of the auction. For example, if the predetermined time is 5 minutes, it is determined whether or not the remaining time is 5 minutes or less, that is, whether or not it is 5 minutes before the end of the auction.

[Step S2]
When the determination means 21 before the predetermined time in FIG. 1 determines that the time is not yet 5 minutes before the auction end time, that is, the remaining time being counted is longer than 5 minutes, the server 2 determines the target product A. Accept bids. Specifically, when browsing access is made from the client device 8 regarding the bid for the target product A, the first bid waiting processing means 23 displays the first bidding screen D1 (FIG. 3A) on the network 6. To display on the client device 8A participating in the auction through the auction. Here, the first bidding screen D1 in FIG. 3A includes a product image display unit 51 that displays information about products such as the image of the target product A and the product name of the target product, and an icon for bidding. Includes a bid instruction display unit 52 for displaying. The first bidding screen D1 also includes a bid remaining time, the latest bid price, and a display indicating that no notification is given regarding the latest bidder (the symbol “?” In FIG. 3A). An information non-notification display unit 53 is included. That is, the auction participant cannot know the latest bid price or the like simply by accessing the web server 2.

[Step S3]
When the bid icon of the bid instruction display unit 52 (FIG. 3A) is selected via the network 6 from the client apparatus 8A of FIG. 1 in which the first bid screen D1 is displayed in this way, One bid determination means 25 determines that. If the first bid determination means 25 does not determine that the bid icon has been selected, that is, if no bid icon has been selected, the process returns to step S1.

[Step S4]
When the first bid determination means 25 in FIG. 1 determines that the bid icon in the bid instruction display section 52 (FIG. 3A) has been selected, the in-bid processing means 27 is the first bid after the start of the auction. In this case, a price obtained by subtracting a predetermined amount (for example, 15 yen) from the starting price stored in the database server 3 is stored in the auction information storage unit 41 related to the corresponding auction of the memory device 4 as the latest bid price, and the first bid Otherwise, a price obtained by subtracting a predetermined amount (15 yen) from the latest bid price stored in the auction information storage unit 41 is stored in the auction information storage unit 41 as the latest bid price. For example, when the latest bid price is 20,000 yen, because the bid has been generated, 15 yen is subtracted from the latest bid price, and 19,985 yen is updated as the latest bid price. In other words, every time a bid is made, the latest bid price is deducted by 15 yen.

  Then, the purchase screen D2 (FIG. 3 (b)) is displayed on the client device 8A that bids for a predetermined display period (15 seconds) via the network 6, and the client devices 8B, 8C, ..., the standby screen D3 (FIG. 3C) is displayed via the network 6 for the same period (15 seconds). As described above, the client device 8A can view the latest bid price by indicating the intention of bidding, but for this purpose, payment of a predetermined fee is required. This payment may be issued to each user at a site provided by the web server of FIG. 1, for example, and the user of the client device may pay this fee using the points on hand. The fee for one bid is, for example, the number of points corresponding to 65 yen, which is larger than the amount subtracted for each bid, that is, 15 yen. Therefore, even if the product price decreases for each bid, a commission income is secured for the auction operator who sells the target product.

  Here, the purchase screen D2 in FIG. 3B includes a product image display unit 51 that displays information about the product such as the image of the target product A and the product name of the target product, the remaining bid time, the latest bid price, And a bid related information display unit 54 for displaying the latest bidder, and a purchase instruction display unit 55 for displaying a purchase icon. In the illustrated case, the bid related information display unit 54 indicates that the remaining bid time is “25:17:57 (25 hours 17 minutes 57 seconds)”, the latest bid price is “19,985 yen”, and the latest bidder Is “User 1”.

  On the other hand, the standby screen D3 in FIG. 3C is a product image display unit 51 that displays information about the product such as the image of the target product A and the product name of the target product, and other client devices are considering purchasing. From the standby display unit 56 for displaying that it is, and a display indicating that notification is not made regarding the remaining bid time, the latest bid price, and the latest bidder (symbol “?” In FIG. 3C). The bid information non-notification display unit 53 is included. As described above, since there is no icon to be selected on the standby screen D3, the user of the client device 8B, 8C,... That is displaying the standby screen D3 is displayed while the standby screen D3 is displayed. Must be waiting.

[Step S5]
Here, when the purchase icon of the purchase instruction display unit 55 is selected in the client apparatus 8A of FIG. 1 in which the purchase screen D2 of FIG. 3B is displayed, the purchase determination means 29 of FIG. Determine. When the purchase determination means 29 does not determine that the purchase icon is selected while the purchase screen D2 (FIG. 3B) is displayed on the client device 8A for a predetermined period (for example, 15 seconds), that is, for 15 seconds. If no purchase icon is selected in the meantime, the process returns to step S1.

[Step S6]
When the purchase determination unit 29 determines that the purchase icon on the purchase screen D2 (FIG. 3B) has been selected, the first sale processing unit 91 includes the target product on the other client devices 8B, 8C,. An auction end notification screen (not shown) including the fact that A has been purchased and the auction has ended is displayed via the network 6, and the sale processing associated with the purchase of the target product from one client device 8 </ b> A is executed. To do. Specifically, for example, settlement processing such as prompting the client device 8A to input a credit card number is executed.

  In this settlement process, the client device 8A can cancel the purchase. That is, in the payment process, a cancel icon is displayed on the web page displayed on the client device 8A, and the client device 8A can select it. If cancellation is performed, the process returns to step S1, and the auction for the target product A is resumed.

[Step S7]
In the above-described step S1, when the remaining time being counted is 5 minutes or less, that is, when the determination means 21 before the predetermined time in FIG. The second bid waiting processing means 93 further accepts a bid for the target product A in the server 2, but the accepting method is different from the case where the remaining time in step S2 is longer than 5 minutes. That is, the second bid waiting processing means 93 displays the second bid screen D4 (FIG. 3 (d)) on all the client devices 8A, 8B, 8C,... Participating in the auction via the network 6. And wait for the bid. Here, the second bidding screen D4 in FIG. 3 (d) includes a product image display unit 51 for displaying information related to products such as an image of the target product A and a product name of the target product, and an icon for bidding. A bid instruction display unit 52 for display is included. The second bidding screen D4 also includes a bid related information display section 54 that displays the remaining bid time, the latest bid price, and the latest bidder.

  Thus, after the remaining time of the auction is less than 5 minutes, all the auction participants can view the bid price. That is, the bid price is displayed on all the client devices 8A, 8B, 8C,. Therefore, there is no need to pay a fee and view the current bid price as in the conventional scratch auction, so the auction participants can follow the ever-decreasing bid price in real time and motivate bidding. Rise. Further, the sales price may be further reduced by applying a discount to the current bid price at this time. Specifically, the number of bids made up to this point n is the profit of the seller who is the auction operator so far, that is, the amount obtained by subtracting 15 yen for each bid from 65 yen per commission. An amount obtained by multiplying a certain 50 yen, that is, n × 50 yen, may be discounted from the current bid price as a sales price. This further increases motivation for auction participants to bid.

[Step S8]
A bid instruction display section 52 (via the network 6 from one of the client devices 8A, 8B, 8C,... Of FIG. 1 on which the second bidding screen D4 of FIG. When the icon for bidding shown in FIG. 3 (d) is selected, the second bid determining means 95 determines to that effect. The second bid issue determination unit 95 repeats the process until it is determined that the bid icon is selected until the auction end time.

[Step S9]
When the second bid determination means 95 determines that the icon for bidding has been selected, the second sale processing means 97 subtracts a predetermined amount from the latest bid price stored in the memory device 4 (15 yen). When the bid price is 0 or less (0 yen or minus), the sale processing associated with the purchase of the target product A from the one client device 8A free of charge is executed. In this case, since the merchandise is free of charge in the buying and selling process, only the process related to the procedure for shipping the goods is performed.

[Step S10]
The second bid determination means 95 determines that the bid icon has been selected, and as a result of subtracting a predetermined amount (15 yen) from the latest bid price stored in the memory device 4, the latest bid price is greater than 0 ( In the case of 1 yen or more), the other client devices 8B, 8C, If the bid instruction display on the second bidding screen D4 (FIG. 3 (d)) is not selected from..., The sales process associated with the purchase of the target product A from one client device 8A is executed. Specifically, for example, settlement processing such as prompting the client device 8A to input a credit card number is executed.

  In this settlement process, the client device 8A can cancel the purchase. That is, in the settlement process, a cancel icon is displayed on the web page, and the client device 8A can select it. If cancellation is performed, the process returns to step S1, and the auction for the target product A is resumed.

  When the buying and selling process is executed, the auction is ended, and the latest bid price and the latest bidder information stored in the auction information storage unit 41 related to the target product A of the memory device 4, that is, the successful bid price and the information about the successful bidder. Is moved to the database server 3. Even if the auction of the target product A is terminated without being successful, the information stored in the auction information storage unit 41 of the memory device 4 is moved to the database server 3.

  As described above, when the time before the auction ends, for example, before 5 minutes, all the auction participants can view the remaining time until the end of the auction and the latest bid information. The auction participants can follow the ever-decreasing bid price in real time, and motivate the bid.
