[0008] Embodiment 1 ***Outline of the Rental Support System*** FIG. 1 is an outline diagram of the rental support system according to this embodiment. The rental support system 100 of this embodiment is composed of, for example, a server 40 connected via a network NW which is an Internet environment, and a plurality of terminal devices used by users who use the system. The terminal device is, for example, a smartphone, and is equipped with a rental program which is an application for using the rental support system 100. In FIG. 1, among the plurality of terminal devices, a first terminal device 50a used by a first user and a second terminal device 50b used by a second user are illustrated.

[0009] A product information database 45 including a list of product information is stored in the server 40. For example, the second user selects and orders a product to be rented from the list of product information displayed on the second terminal device 50b. Note that the list of product information is information based on the product information database 45. Then, the ordered product is shipped from the user who used the product first to the second user. In this way, the rental support system 100 is a system that realizes a rental support service for so-called sharing rental, in which the product is shipped from the user who used the product first to the next user. Note that sharing rental is also called re-lending.

[0010] In addition, the rental support system 100 may further include a corporate computer 60. The corporate computer 60 is a computer of a company that provides products used in the rental support service, and updates the list of product information of the server 40 to the latest information. In addition, the corporate computer 60 is also used for managing sales such as rental fees by the rental support service.

[0011] ***Block Configuration of Each Device*** FIG. 2 is a functional block diagram of each device in the rental support system. First, the configuration of the server 40 will be described.

[0012] The server 40 is the host server of the rental support system 100 and is composed of a control unit 41, an arithmetic unit 42, a communication unit 43, a storage unit 44, etc. The control unit 41 is configured to include one or more processors.

The display unit 52a is configured to include a display device such as a liquid crystal display or an organic EL (Electro Luminescence) display, and displays an image based on image data. Note that the display unit 52a includes a touch panel and also functions as an input unit.

[0015] The communication unit 53a preferably uses a wireless communication module compliant with the wireless LAN standard. Note that it is not limited to wireless LAN, and any configuration that can be connected to the network NW is acceptable. For example, it may be connected to the network NW via a telephone line such as a mobile communication system. The storage unit 54a is composed of memories such as RAM and ROM. The storage unit 54a stores the OS, application programs, and various data. The application programs include the rental terminal program 57. Here, the first terminal device 50a has been described as a representative, but the second terminal device 50b has the same configuration. Note that it is not limited to a smartphone, and any terminal device with similar functions is acceptable. For example, it may be a tablet terminal device or a personal computer such as a notebook PC.

[0016] The enterprise computer 60 is, for example, a notebook PC and is composed of a control unit 61, a communication unit 62, a storage unit 63, and the like. The control unit 61 is configured to include one or more processors. The control unit 61 comprehensively controls the operation of the enterprise computer 60 by operating according to the OS and application programs stored in the storage unit 63. The communication unit 62 uses, as a preferred example, a module for wireless communication compliant with the wireless LAN standard. Note that it is not limited to wireless communication, and any configuration that can be connected to the network NW is acceptable. For example, it may be equipped with a wired LAN port and may be wired-connected to the network NW via a LAN cable. The storage unit 63 is composed of memories such as RAM and ROM. The storage unit 63 stores an OS, application programs, various data, etc. The various data includes a product information database 65 and a sales management database 66.

[0017] ***Flow of the share rental process*** Figure 3 is a flowchart showing the flow of the share rental process. Figure 4 is a diagram showing an example of the screen of the product information list. Here, mainly with reference to Figure 3 and appropriately referring to Figure 4, the flow of the share rental process by the rental support system 100 will be described.

[0018] In step S10, the server 40 publishes the list of product information in the product information database 45 of the storage unit 44 via the network NW. Note that in the server 40, the rental core program 48 is running, and the content of the product information database 45 is updated by the enterprise computer 60.

[0019] Next, the operation of the second terminal device 50b will be described. In step S30, on the second terminal device 50b, the list of product information published by the server 40 is displayed on the display unit 52b. This is because the second user who owns the second terminal device 50b starts the rental terminal program 57 and performs an operation to select a product for which rental is desired.

[0020] Figure 4 shows the screen 70 displayed on the display unit 52b of the second terminal device 50b. The screen 70 includes a list of product information 71, a product image 72, a product description 73, etc. On screen 70, the screen name "Rental Product List" is displayed in the upper left corner. Below the screen name, a product image 72, which is a photo of the product selected by the second user, is displayed. To the upper right of the product image 72, the product model number "PG8X2" is displayed. Also, below the product image 72, product images 75 of similar products are displayed. The product images 75 are photos with a size smaller than that of the product image 72, and the product model number "PG8X1" is displayed in the upper right corner of the image. The product images 72 and 75 are, as an example, digital cameras. The difference between the product image 72 and the product images 75 is that the body color tone is different. Note that the product is not limited to a camera, and any product that can be delivered between users is acceptable. For example, it may be electronic devices such as printers and projectors, household electrical appliances such as TVs, refrigerators, and washing machines, musical instruments, hobby products such as leisure supplies, etc.

[0021] In the product information list 71, a product number, manufacturer name, model number, user name, rental availability, and rental order column are provided. The product number is the sequential number of the product. The manufacturer name is the name of the product manufacturer. The model number is the manufacturer model number of the product. The user name is the symbolized name of the user who currently holds the product. The rental availability is an identification column indicating whether the product can be shared and rented. If it is "〇", it can be rented again; if it is "×", it cannot be rented again. For products that can be rented again with "〇", an "Order Button" is displayed in the rental order column. Also, the product information list 71 is displayed sorted by the same model number of products. For example, when the user clicks on a product image 75 with a different color tone, the product information list is sorted and displayed by the model number of the product image 75.

[0022] Return to Figure 3. In step S31, it is determined whether there is an order for the product in the product information list 71 of the second terminal device 50b. If there is an order for the product, the process proceeds to step S32. If there is no order for the product, the process returns to step S30. Here, it is assumed that the second user who owns the second terminal device 50b presses the "Order Button" in the rental order column for product No. "0001" in the product information list 71. When the "Order Button" of the display unit 52b that functions as an input unit is pressed, the screen switches to an order information input screen, and the second user inputs order information including the rental period and the location information of the place where it will be used. In step S32, the second terminal device 50b transmits the order information for product No. "0001" from the communication unit 53b as the second communication unit.

[0023] Return to the operation of the server 40. Next, in step S11, the server 40 determines whether there is order information from the terminal device. If order information is received, the process proceeds to step S12. If order information is not received, the server 40 continues to wait for order information in step S11. In step S12, the server 40 reads the received order information. In step S13, the server 40 collates the content of the read order information with the lending information database 46 and the user information database 47 in the storage unit 44. The current location information of product No. "0001" is stored in the lending information database 46. The contact information of the first user who is the current holder of product No. "0001" is stored in the user information database 47.

[0024] In step S14, the server 40 sends a shipping request notice to the first terminal device 50a of the first user, which has been verified based on the order information, requesting it to ship the first product to the address of the location information of the order form. Specifically, a shipping request notice for shipping product No. "0001" as the first product is sent to the first terminal device 50a. In other words, when the server 40 receives the order information from the second terminal device 50b, it sends a request notice to the first terminal device 50a to ship the first product to the address of the location information of the order information based on the order information. Note that the shipping request notice also includes an invoice requesting the first user to pay the rental fee for the first product. The invoice contains information such as the rental fee and the transfer account. The rental fee is the rental fee until the shipping date of the first product.

[0025] Next, the operation of the first terminal device 50a will be described. In step S20, the first terminal device 50a determines whether it has received a shipping request notice from the server 40. If it has received the shipping request notice, it proceeds to step S21. If it has not received the shipping request notice, it continues to wait for the shipping request notice in step S20. When the shipping request notice is received, the first user ships product No. "0001" to the address of the location information of the order form specified in the shipping request notice. Then, in step S21, the first terminal device 50a sends a product shipping report notice indicating that the product has been shipped.

[0026] Return to the operation of the server 40. In step S15, the server 40 determines whether it has received a product shipping report notice from the terminal device. If it has received the product shipping report notice, it proceeds to step S16. If it has not received the product shipping report notice, it continues to wait for the product shipping report notice in step S15. In step S16, when the server 40 receives the merchandise shipment report notification, it refers to the lending information database 46 to calculate the scheduled arrival date of the first merchandise. Specifically, the scheduled arrival date of the merchandise is calculated from the location of the sender of merchandise No. "0001" and the location information of the destination. Note that the merchandise shipment report notification includes payment information proving that the first user has paid the lending fee for the first merchandise. The server 40 transmits the said payment information to the enterprise computer 60. In step S17, the server 40 transmits an arrival schedule notification including the calculated scheduled arrival date of the merchandise to the second terminal device 50b. In other words, when the server 40 receives a notification indicating that the merchandise has been shipped from the first terminal device 50a, it refers to the lending information database 46 to calculate the scheduled arrival date of the first merchandise, and transmits the calculated scheduled arrival date of the merchandise to the second terminal device 50b.

[0027] Return to the operation of the second terminal device 50b. In step S33, the second terminal device 50b receives the arrival schedule notification. In step S34, the second terminal device 50b displays the received arrival schedule notification on the display unit 52b.

[0028] As described above, according to the rental support system 100 of the present embodiment, the following effects can be obtained. The rental support system 100 is a system in which a first terminal device 50a used by a first user, a second terminal device 50b used by a second user, and a server 40 are connected via a network, and which supports the sharing rental of a first product between the first user who is borrowing the first product and the second user. Specifically, the first terminal device 50a has a communication unit 53a as a first communication unit, and the second terminal device 50b has a display unit 52b that displays a list of product information published by the server 40, and in the list of product information, a display unit 52b as an input unit for selecting a product for which rental is desired and inputting the rental period and location information of the place of use, and a communication unit 53b as a second communication unit that transmits order information including the rental period and location information. The server 40 has a communication unit 43 as a third communication unit, a product information database 45 including a list of product information, a rental information database 46 including the rental period information of the product being rented and the location information of the product being rented, and a user information database 47 including the registration information of users including the first user and the second user. When the server 40 receives order information from the second terminal device 50b, based on the order information, the server 40 transmits a request notification to ship the first product to the address of the location information in the order form to the first terminal device 50a, and when it receives a product shipment report notification indicating that the product has been shipped from the first terminal device 50a, it refers to the rental information database 46 to calculate the expected arrival date of the first product, and transmits an expected arrival notification including the calculated expected arrival date of the product to the second terminal device 50b.

[0029] According to this system, the first product possessed by the first user can be directly shipped from the first user to the second user and lent to the second user. Therefore, unlike the conventional rental service in which lending and returning of products are performed with a rental company as a hub, according to the rental support system 100, the storage warehouse can be simplified. Therefore, it is possible to provide a rental support system 100 with good rental efficiency through re-lending among users.

[0030] In addition, in the conventional rental service, even if the next borrower is determined, the previous borrower still needs to return the item to the rental company. The next borrower cannot rent the item until after the previous borrower's return and after going through procedures such as product inspection and maintenance period, resulting in poor rental efficiency. Specifically, it was necessary to secure a storage warehouse and management man-hours of a scale corresponding to the scale of the items subject to rental. Also, when transporting the item, it is necessary to return it to the rental company serving as a hub and then deliver it from the rental company to the next borrower, incurring round-trip transportation costs. Moreover, since a certain number of days for management are required from the time the item is returned until it can be re-rented, the rental efficiency per unit time is limited. On the other hand, according to the rental support system 100 of the present embodiment, since sub-lending is possible among users, the above problems in the conventional rental service can be solved, and the rental efficiency can be significantly improved. Specifically, in addition to being able to simplify the storage warehouse, the management man-hours can also be compressed. Furthermore, since the item is directly delivered between the lender and the borrower, timely item rental becomes possible, the transportation days are shortened, and the transportation costs can also be suppressed. That is, the rental efficiency can be significantly increased compared to the conventional rental service.

[0031] Also, the product information list 71 is arranged and displayed for each product of the same model number. According to this, since the products are arranged and displayed by model number, it is easy for the user to select the desired product.

[0032] Embodiment 2 ***Method for Determining a User from Multiple Applicants*** FIG. 5 is a flowchart showing the processing flow of the method for determining a user from multiple applicants according to the present embodiment, corresponding to FIG. 3. In Embodiment 1, the process of lending a product to a single potential user was described, but the present invention is not limited thereto. For example, when there are multiple potential users who have ordered the first product, the next user may be determined based on the order of receiving the order information and determination items including the distance between the current location of the first product and the location of the potential user. Hereinafter, the same component parts as those in Embodiment 1 are assigned the same reference numerals, and redundant descriptions are omitted.

[0033] In FIG. 3, when there are multiple potential users of the first product, the user is determined by performing the following process in step S16. Hereinafter, the description will be mainly based on FIG. 5 and with reference to FIG. 3. In step S60, the server 40 determines whether there is a plurality of order information. If there is a plurality of order information, the process proceeds to step S61. If there is not a plurality of order information, the process proceeds to step S65. In step S65, the process returns to the flowchart of FIG. 3, and the process of step S16 is executed.

[0034] In step S61, the server 40 reads a plurality of order information. Specifically, while reading a plurality of order information, determination items including the order of receiving the order information and the distance between the current location of the first product and the location of the potential user, which are used in the following calculation, are collated with each database and tabulated as a data table in the storage unit 44. In step S62, the server 40 determines the next user of the first product based on the calculation of the following formula (1). Then, the scheduled arrival date of the product to the next user is calculated.

[0035] Next user = max{(Kr / Ri + Kd / Di) × (Lj - Pi)} … Formula (1)

[0036] In Formula (1), Kr is a weighting coefficient of the reservation order based on the order of receiving the order information. Ri is the reservation order of user i. Kd is a weighting coefficient of the distance. Di is the number of days for transporting the product according to the distance between user i and the current user. Lj is the number of days until the lending deadline determined by the current user j. Pi is the number of rental days desired by user i.

[0037] In step S63, the calculation of formula (1) is performed for each of the multiple users who wish to use the item, and the user with the maximum result is determined as the next user. Then, from the transportation days Di, the scheduled arrival date of the item to the next user is calculated. In other words, the server 40 determines the user of the first item by performing a calculation based on the order of receiving order information among multiple users who wish to use the item and determination items including the distance between the current location of the first item and the location of the user who wishes to use the item, and then calculates the scheduled arrival date of the item. Note that it is not limited to determining the next user by formula (1), and the next user may be determined based on the order of receiving order information and determination items including the distance between the current location of the first item and the location of the user who wishes to use the item.

[0038] In step S64, the server 40 returns to the process of step S17 in FIG. 3. Specifically, a scheduled arrival notice including the scheduled arrival date of the item is sent to the second terminal device 50b of the determined next user.

[0039] As described above, according to the rental support system 100 of the present embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. When there are multiple users who wish to use the item, that is, users who have ordered the first item, the server 40 receives a notice indicating that the item has been shipped from the first terminal device 50a, and when calculating the scheduled arrival date of the first item by referring to the lending information database 46, the server 40 determines the user of the first item by performing a calculation based on the order of receiving order information among multiple users who wish to use the item and determination items including the distance between the current location of the first item and the location of the user who wishes to use the item, and then calculates the scheduled arrival date of the item.

[0040] According to this, since the user is determined by performing a calculation based on the order of receiving the order and determination items including the transportation distance of the item, it is possible to shorten the transportation days and reduce the transportation cost, and efficient sharing rental can be performed.

[0041] Embodiment 3 ***Evaluation of Lenders and Information Exchange with Lenders*** FIG. 6 is a diagram showing an example of an evaluation list screen of lenders according to the present embodiment, corresponding to FIG. 4. FIG. 7 is a diagram showing an example of a chat screen between a lender and a user who wishes to use the item, corresponding to FIG. 6.

[0042] In Embodiment 1, it was described that the first item in the list of lendable items in the item information list is ordered. However, items may be selected with reference to the evaluations of other users for the lenders. Also, information exchange with the lender by chat about items of interest may be used as a reference for item selection. Hereinafter, the same component parts as those in Embodiment 1 are given the same reference numerals, and duplicate explanations are omitted.

[0043] In the item information list 71 of FIG. 4, for example, when the user name "111u" of item No. "0001" is clicked, the screen 80 of FIG. 6 is transitioned to. In other words, when a predetermined user is selected from the list display of the item information list 71, the screen switches to the screen 80 on which the evaluation result for the predetermined user is displayed. The screen 80 of FIG. 6 is an evaluation list screen of the evaluations received by the user "111u" as a lender from other users in past transactions. At the upper left of the screen, "Evaluation List of Mr. 111u" and the content of the screen are displayed. Below the display of the screen content, an evaluation list table 81 is displayed. The evaluation list table 81 has three evaluation items: good "◎", normal "〇", and bad "△". For each item, the number of people and the percentage (%) are displayed. It can be understood that 78% of the users evaluate the lender Mr. "111u" as good "◎", and when including normal "〇", 94% of the users evaluate the lender as a normal or better lender. Also, below the evaluation list table 81, the individual evaluation comments of the users who evaluated as good "◎" are displayed.

[0044] To the right of the evaluation list 81, there is an operation button 82 displayed as "Chat with Mr. 111u". When the operation button 82 is clicked, it transitions to the screen 90 in FIG. 7. In other words, on the screen 80 where the evaluation results for a predetermined user are displayed, there is an operation button 82 for chatting with the predetermined user. The screen 90 in FIG. 7 is a chat screen for information exchange between the questioner who operated the operation button 82 and the lender "111u". On the left side of the screen 90, the lender Mr. "111u"'s speech is displayed, and on the right side, the questioner Mr. "827a"'s speech is displayed. On the screen 90, in response to the questioner Mr. "827a"'s speech "Hello, please tell me about PG8X2.", the lender Mr. "111u" responds with "Yes, what kind of content would you like?", and an example of information exchange taking place is illustrated.

[0045] As described above, according to the rental support system 100 of the present embodiment, in addition to the effects in the above embodiment, the following effects can be obtained. In the product information list 71, the product numbers indicating the first product and the users including the first user are listed. When a predetermined user is selected from the list display, it switches to the screen where the evaluation results for the predetermined user are displayed.

[0046] According to this, when a user wishes to rent a product, they can refer to the past evaluation results of the lender.

[0047] Also, on the screen 80 where the evaluation results for a predetermined user are displayed, there is an operation button 82 for chatting with the predetermined user.

[0048] According to this, a user wishing to rent can exchange information with the owner of the product about points of interest regarding the product to be rented, etc., using chat.
