Next, specific examples of data structures of the product information DB 131, the store information DB 132, and the purchase candidate list DB 133 stored in the server device 1 will be described.

  FIG. 4A is an example of the data structure of the product information DB 131. In the product information DB 131 shown in FIG. 4A, the title, author, and price of a book that is a product are associated with each product ID. In addition to the items shown in FIG. 4A, the product information DB 131 may be associated with various information such as book genre information, publisher information, and publication date information.

  FIG. 4B is an example of the data structure of the store information DB 132. In the store information DB 132 shown in FIG. 4B, for each store, a store ID indicating a store identification number, a store name, a store position represented by latitude and longitude, and a product ID (“ Also referred to as “stock item ID”) and the number of stocks. In FIG. 4B, the inventory quantity is displayed with parentheses on the right side of the inventory product ID.

  The server device 1 appropriately updates the inventory product ID and the inventory quantity of each store registered in the store information DB 132. For example, the server device 1 is connected to a terminal (also referred to as a “POS terminal”) that manages point-of-sale information (POS: Point of Sale) for each store, and receives information on the inventory of each product from these terminals. Thus, the stock product ID and the stock quantity of each store are updated. In addition, the server apparatus 1 may update the stock product ID and the stock quantity information of each store registered in the store information DB 132 based on a user input to an input unit (not shown).

  FIG. 4C is an example of the data structure of the purchase candidate list DB 133. In the purchase candidate list DB 133 shown in FIG. 4C, for each user, a user ID and a list of product IDs of purchase candidate products designated by the user (that is, purchase candidate list Lc) are associated.

  When the server device 1 receives the list addition request S2 from the user terminal 3, the server device 1 updates the purchase candidate list DB 133. Specifically, the server device 1 adds the product ID included in the list addition request S2 to the product candidate list Lc of the purchase candidate list DB 133 corresponding to the user ID included in the list addition request S2.

  Further, preferably, when the user of the user terminal 3 purchases a purchase candidate product at any store, the server device 1 sets the product ID of the purchase candidate product to the corresponding product candidate list in the purchase candidate list DB 133. It is good to delete from Lc. For example, when the store POS terminal reads the user ID stored in the point card presented to the store clerk at the time of purchase by the user, the POS terminal transmits the read user ID together with the product ID of the purchased product to the server device 1. To do. When the received user ID and product ID are associated in the purchase candidate list DB 133, the server device 1 deletes the product ID.

[Processing flow]
Next, the display method of the product screen based on this embodiment will be described with reference to the flowcharts of FIGS.

  FIG. 5 is an example of a flowchart illustrating a procedure of a store search process based on the purchase candidate list Lc executed by the server device 1 and the user terminal 3.

  First, the user terminal 3 determines whether or not there is an input for instructing a store search based on the purchase candidate list Lc (step S101). And when the user terminal 3 judges that there was an input which instruct | indicates the shop search based on the purchase candidate list Lc (step S101; Yes), the shop search request | requirement S1 containing a user ID is transmitted to the server apparatus 1 (step). S102). Note that the user terminal 3 may not include the user ID in the store search request S1 when the user ID has already been transmitted to the server device 1 at the time of login authentication or the like. On the other hand, when there is no input for instructing a store search based on the purchase candidate list Lc (step S101; No), the user terminal 3 continuously monitors whether or not there is the above input in step S101.

  The server device 1 that has received the store search request S1 transmitted by the user terminal 3 acquires the purchase candidate list Lc corresponding to the user ID included in the store search request S1 from the purchase candidate list DB 133 (step S201). Then, the server device 1 determines whether or not the number of purchase candidate products included in the purchase candidate list Lc (also simply referred to as “list registration number NL”) is greater than “0” (step S202). That is, the server device 1 determines whether or not a product ID indicating at least one purchase candidate product is included in the purchase candidate list Lc extracted from the purchase candidate list DB 133.

  If the number of purchase candidate lists Lc is greater than “0” (step S202; Yes), the server device 1 executes step S203 and step S204 described later. On the other hand, when the number of purchase candidate lists Lc is “0” (step S202; No), that is, when the user of the user terminal 3 does not register the purchase candidate product in the server device 1, the server device 1 performs the flowchart. Terminate the process. In this case, the server device 1 may notify the user terminal 3 that the store search cannot be executed because the purchase candidate product is not registered.

  Next, for each store registered in the store information DB 132, the server device 1 has the number of items in stock (also referred to as “the number Nm in stock”) among the purchase candidate products indicated by each product ID in the purchase candidate list Lc. Is calculated (step S203). And the server apparatus 1 produces | generates the display information of the search result screen which arranged the information of the store in order with the largest stock number Nm, and transmits the said display information to the user terminal 3 (step S204). In this case, preferably, the server device 1 may generate display information of a search result screen in which stores having a stock count Nm of “1” or more are arranged. Further, the server device 1 may generate display information of a search result screen in which only the information of the upper predetermined number of stores having a large number of items in stock Nm is arranged.

  Then, the user terminal 3 displays a search result screen based on the display information received from the server device 1 (step S103). Thereby, the user of the user terminal 3 can see a list of stores that handle a large number of registered purchase candidate commodities, and can appropriately determine a store to be a destination.

  In another example, when the store information DB 132 includes information on the return rate of points (points) to be given as purchase privileges, the server device 1 arranges stores on the search result screen based on the return rate of points. The order may be determined. For example, the server device 1 recognizes the return rate of points with respect to the purchase price by referring to the store information DB 132 for each of the top predetermined number of stores having a large number Nm in stock, and searches in descending order of the return rate. Determine the order of stores on the result screen.

(Modification 2)
The server device 1 may search for a store or a combination of stores that can purchase all the products in the purchase candidate list Lc, and may transmit display information indicating the search result to the user terminal 3.

  FIG. 12 is a display example of a search result screen according to the modification. In the search result screen of FIG. 12, the server device 1 is another purchase that cannot be purchased at a favorite store on the assumption that the user of the user terminal 3 stops at a favorite store (store F in this case) registered in the server device 1 in advance. A store or a combination of stores where candidate products can be purchased are arranged. In this case, the server device 1 stores in advance, in the purchase candidate list DB 133 and the like, the store ID and the like of the favorite store registered by each user in association with the user ID. In FIG. 12, the server device 1 arranges the arrangement order on the search result screen in a higher order as the number of combinations decreases, and when the number of combinations is the same, the distance from the favorite store to each store is displayed. The shorter the total, the higher the order.

  Here, a supplementary description will be given of a method of generating display information on the search result screen of FIG. First, since the number Nm of stocks in the store F, which is a favorite store, is 13 (the list registration number NL is 20), the server device 1 has the remaining 7 purchase candidate products that are not in stock in the store F. The store with the stock is searched with reference to the store information DB 132. As a result, the server device 1 determines that each of the store A and the store B has the inventory of the remaining seven purchase candidate products that are not in stock in the store F. Arrange the information on the store B next to the store A. Next, the server device 1 searches the store information DB 132 for a combination of two stores that have inventory of the remaining seven purchase candidate products that are not in stock in the store F. As a result, the server device 1 determines that there is an inventory of the remaining seven purchase candidate products that are not in stock in the store F in either the store H or the store G, and either the store Q or the store R. In addition, it is determined that there is an inventory of the remaining seven purchase candidate products that are not in stock in the store F. Therefore, in this case, the server device 1 arranges the combination of the store H and the store G and the combination of the store Q and the store R in the third and fourth positions, respectively. Here, the server apparatus 1 arranges the combination of the store H and the store G (total 9 km) having a short total distance from the favorite store to each store higher than the combination of the store Q and the store R (total 11 km). Yes. Note that the server device 1 may further search for a combination of three or more stores that have inventory of the remaining seven purchase candidate products that are not in stock in the store F, and display them side by side on the search result screen.

  According to this example, on the premise that the server device 1 stops at the favorite store “Store F”, the user can suitably grasp the combination of stores where all the products in the registered purchase candidate list Lc can be purchased, Convenience can be improved. In the example of FIG. 12, the server device 1 is premised on a stop at a favorite store registered in advance by the user of the user terminal 3, but it is not premised on a stop at the favorite store, and the entire purchase candidate list Lc is stored. Any store or combination of stores where the product can be purchased may be searched and displayed side by side on the search result screen. Even in this case, for example, the server device 1 arranges the order on the search result screen in a higher order as the number of combinations is smaller, and when the number of combinations is the same, the user terminal 3 and the store The shorter the distance, the higher.

(Modification 3)
The server device 1 may cause the user terminal 3 to display a store-specific inventory confirmation screen for a store where the user terminal 3 has approached within a predetermined distance.

  In this case, the user terminal 3 transmits the position information and user ID measured by the GPS receiver or the like to the server device 1 at predetermined intervals. Then, the server device 1 calculates the distance between the position indicated by the position information received from the user terminal 3 and the position of each store registered in the store information DB 132, and falls within a predetermined distance that is a predetermined threshold. It is determined whether or not. And if the server apparatus 1 detects the shop which exists within the predetermined distance from the user terminal 3, the purchase candidate list Lc corresponding to the user ID received together with the position information is extracted from the purchase candidate list DB 133, and the user Is referred to from the store information DB 132. As a result, the server device 1 generates display information of the store-specific inventory confirmation screen targeting the store that the user has approached, and transmits the display information to the user terminal 3. Then, the user terminal 3 displays a store-specific inventory confirmation screen as shown in FIG. 10 based on the received display information. Thereby, the server apparatus 1 can make a user recognize suitably whether the goods of the purchase candidate list | wrist Lc are in the store where the user passed nearby.

(Modification 4)
After performing the reserve based on the selection of the collective reserve button 66A or the individual reserve buttons 66B to 66E on the store-by-store inventory confirmation screen in FIG. 10, when a predetermined time (for example, 24 hours) has elapsed, the server device 1 automatically You may cancel the reserve procedure. In this case, the server apparatus 1 returns the number of stocks reduced by the reserve in the store information DB 132 and transmits instruction information for canceling the reserve to the POS terminal or the like of the store that has instructed the reserve.

(Modification 5)
The products handled by the store search system 100 are not limited to books. For example, the store search system 100 may deal with music and movie playback media and various other products in addition to or instead of books.

(Modification 6)
The server device 1 may be composed of a plurality of servers. For example, the server device 1 may be composed of a server having the product information DB 131, a server having the store information DB 132, a server having the purchase candidate list DB 133, and a server that executes the process of FIG. In this case, these servers function as a “search device” in the present invention, and exchange information necessary for assigned processing.

(Modification 7)
In the store-by-store inventory confirmation screen of FIG. 10, the server device 1 displays the numerical value of the number of inventory of purchase candidate products in stock on the user terminal 3. However, the display mode of the store-specific inventory confirmation screen to which the present invention is applicable is not limited to this.

  FIG. 13 is a display example of a store-specific inventory confirmation screen according to a modification. In the example of FIG. 13, the server device 1 displays information representing the number of stocks of each purchase candidate product registered by the user of the user terminal 3 for each purchase candidate product. Specifically, the server apparatus 1 represents the inventory status of purchase candidate products whose inventory quantity is equal to or greater than a predetermined threshold (for example, 3) by “◯”, and the inventory quantity is 1 or more and less than the above threshold. The inventory status of the purchase candidate product is represented by “Δ”, and the inventory status of the purchase candidate product whose inventory quantity is 0 is represented by “x”. Also according to this display mode, the server device 1 can allow the user of the user terminal 3 to appropriately grasp the stock status of each purchase candidate product registered by the user of the user terminal 3.
