The merchandise sales system according to Embodiment 1 includes a locker device 10 having a plurality of lockers for storing merchandise such as boxed lunches, and a ticket vending machine 20 from which a customer selects a product to purchase.

[0021] As shown in Figure 1(a), in this product sales system, when replenishing products, the locker number to be replenishing is specified on the display operation unit 11 of the locker device 10 (S1). Then, the QR code (registered trademark) attached to the product is read by the code reader 12 (S2). Product information such as the product name and price is encoded in this QR code (registered trademark).

[0022] As shown in Figure 1(b), when a product is restocked in a designated locker (S3), information including the product information and the locker number (hereinafter referred to as "product storage information") is notified to the ticket vending machine 20 (S4). The ticket vending machine 20 updates the menu screen using the received product storage information (S5). For example, the menu screen displays the product information for the restocked product, "B Lunch Fried Chicken, 550 yen."

[0023] In this way, in the product sales system of this embodiment 1, when replenishing products in the locker device, the product code containing the product information is read, and once the locker device is replenishing with products, the product storage information is notified to the ticket vending machine, and the ticket vending machine updates the menu screen.This effectively prevents inconsistencies between the products stored in the multiple storage sections of the vending machine and the menu screen on which the products are selected.

[0024] <Configuration of Locker Device 10> The configuration of the locker device 10 shown in Fig. 1 will be described. Fig. 2 is a functional block diagram showing the configuration of the locker device 10 shown in Fig. 1. As shown in Fig. 2, the locker device 10 has a display operation unit 11, a code reader 12, a storage unit 13, a communication unit 14, a memory unit 15, and a control unit 16.

[0025] The display operation unit 11 is an input / output device such as a touch panel display. The code reader 12 is an input device that reads QR codes (registered trademark). The storage unit 13 is made up of multiple lockers, and products are stored in each locker. The communication unit 14 is an interface unit for data communication with the ticket vending machine 20.

[0026] The storage unit 15 is a storage device such as a hard disk drive or nonvolatile memory, and stores mode data 15a, replenishment method data 15b, and locker number data 15c.

[0027] The mode data 15a indicates the mode of the locker device 10. The modes of the locker device 10 include a sales mode and a replenishment mode. The replenishment method data 15b indicates the replenishment method of the products. The locker number data 15c indicates the locker number currently being designated.

[0028] The control unit 16 is a control unit that performs overall control of the locker device 10, and includes a mode control unit 16a, a product replenishment control unit 16b, a locker selection unit 16c, a product information acquisition unit 16d, a storage confirmation unit 16e, an unlocking control unit 16f, a door opening / closing processing unit 16g, a locking control unit 16h, and a sales control unit 16i. In practice, by loading and executing these programs into a CPU (Central Processing Unit), the mode control unit 16a, the product replenishment control unit 16b, the locker selection unit 16c, the product information acquisition unit 16d, the storage confirmation unit 16e, the unlocking control unit 16f, the door opening / closing processing unit 16g, the locking control unit 16h, and the sales control unit 16i execute their respective corresponding processes.

[0029] The mode control unit 16a is a processing unit that controls the mode of the locker device 10. When the mode data 15a is in the "sales mode," if the mode control unit 16a receives an employee QR code (registered trademark) from the code reader 12, the mode control unit 16a transitions the mode of the locker device 10 to the replenishment mode and updates the mode data 15a to the "replenishment mode."

[0030] When the mode control unit 16a receives an employee QR code (registered trademark) from the code reader 12 while the mode data 15a is in the "replenishment mode," it transitions the mode of the locker device 10 to the sales mode and updates the mode data 15a to the "sales mode."

[0031] The product replenishment control unit 16b is a processing unit that controls product replenishment. When the mode control unit 16a switches the locker device 10 to replenishment mode, the product replenishment control unit 16b displays a replenishment method selection screen on the display operation unit 11. The replenishment methods displayed are "individual set," "single row set," and "full set." When a replenishment method is selected on the replenishment method selection screen, the selected replenishment method is stored in the replenishment method data 15b.

[0032] When the locker number data 15c is updated by the locker selection unit 16c, the product replenishment control unit 16b displays a product information reading screen on the display operation unit 11.

[0033] When the product replenishment control unit 16b receives a product replenishment completion notification from the locker selection unit 16c or the storage confirmation unit 16e, it clears the replenishment method data 15b and the locker number data 15c to zero and displays a set completion screen on the display operation unit 11. Then, when the "Confirm" button is accepted on the set completion screen, it displays a replenishment method selection screen.

[0034] The locker selection unit 16c is a processing unit that selects a locker to replenish with products. If "individual set" is selected on the replenishment method selection screen, the locker selection unit 16c displays an individual set selection screen. Then, if a locker number is accepted on the individual set selection screen, the locker selection unit 16c stores the locker number in the locker number data 15c.

[0035] If "single row set" is selected on the replenishment method selection screen, the locker selection unit 16c displays the single row set selection screen. Then, if the row number to replenish products is accepted on the single row set selection screen, the locker selection unit 16c specifies the lowest locker number in this row. For example, if row C is accepted, the locker selection unit 16c specifies "C1". The specified locker number is then stored in the locker number data 15c.

[0036] If "Set all" is selected on the replenishment method selection screen, the locker selection unit 16c designates the locker number as "A1" and stores it in the locker number data 15c.

[0037] When the locker selection unit 16c receives a locker designation instruction from the storage confirmation unit 16e, it performs the following process. If the replenishment method data 15b is "set in one row," and the locker number data 15c is the last locker number in the designated row, it passes a product replenishment completion notification to the product replenishment control unit 16b. If it is not the last locker number, it updates the locker number data 15c by changing the current locker number to the next locker number. For example, if the current locker number is "C3," it stores the next locker number, "C4," in the locker number data 15c. If the replenishment method data 15b is "set all," and the locker number data 15c is the last locker number in the locker device 10, it passes a product replenishment completion notification to the product replenishment control unit 16b. If it is not the last locker number, it updates the locker number data 15c by changing the current locker number to the next locker number.

[0038] The product information acquisition unit 16d is a processing unit that acquires information about a product. When the product information acquisition unit 16d reads a QR code (registered trademark) attached to a product using the code reader 12 while the product information reading screen is displayed, the product information acquisition unit 16d displays product storage information including the read data and the locker number specified by the locker number data 15c on the product information confirmation screen.

[0039] The storage confirmation unit 16e is a processing unit that confirms the replenishment of products in the lockers. When the storage confirmation unit 16e receives a "Confirm" button on the product information confirmation screen, it displays a product set confirmation screen to prompt the user to replenish the specified locker with products, and passes an unlock instruction to the unlock control unit 16f.

[0040] When the storage confirmation unit 16e receives a closing completion notification from the door opening / closing processing unit 16g, it displays a "Setting Complete" button in a state where it can accept it on the product setting confirmation screen. Then, when the "Setting Complete" button is accepted, it passes a locking instruction to the locking control unit 16h.

[0041] When the storage confirmation unit 16e receives a locking completion notification from the locking control unit 16h, it notifies the ticket vending machine 20 of the product storage information. If the replenishment method data 15b is "individual set", it passes the product replenishment completion notification to the product replenishment control unit 16b. If the replenishment method data 15b is "single row set" or "all set", it passes a locker designation instruction to the locker selection unit 16c.

[0042] The unlocking control unit 16f is a processing unit that unlocks the door of a specified locker. When the unlocking control unit 16f receives an unlocking instruction from the storage confirmation unit 16e or the sales control unit 16i, the unlocking control unit 16f unlocks the door of the locker stored in the locker number data 15c.

[0043] The door opening / closing processing unit 16g is a processing unit that performs processing to confirm whether the door of the specified locker is open or closed. When the door of a locker unlocked by the unlocking control unit 16f is opened and then closed, the door opening / closing processing unit 16g performs the following processing. If the mode data 15a is the "replenishment mode", it passes a closing completion notification to the storage confirmation unit 16e. If the mode data 15a is the "sales mode", it passes a closing completion notification to the sales control unit 16i.

[0044] The locking control unit 16h is a processing unit that locks the door of a specified locker. When the locking control unit 16h receives a locking instruction from the storage confirmation unit 16e, the locking control unit 16h locks the door of the locker stored in the locker number data 15c and passes a locking completion notification to the storage confirmation unit 16e.

[0045] When the locking control unit 16h receives a locking instruction from the sales control unit 16i, it locks the door of the locker stored in the locker number data 15c and sends a locking completion notification to the sales control unit 16i.

[0046] The sales control unit 16i is a processing unit that controls the sale of products. When the mode data 15a is in the "sale mode", the sales control unit 16i displays on the display operation unit 11 that the product is on sale.

[0047] When the sales control unit 16i receives the locker number from the ticket vending machine 20, it stores the locker number in the locker number data 15c and passes an unlock instruction to the unlock control unit 16f.

[0048] When the sales control unit 16i receives a closing completion notification from the door opening / closing processing unit 16g, it passes a locking instruction to the locking control unit 16h. When the sales control unit 16i receives a locking completion notification from the locking control unit 16h, it notifies the ticket vending machine 20 of sales completion information including the locker number of the locker number data 15c. Then, it clears the locker number data 15c to zero.

[0049] Next, an example of data stored in the storage unit 15 of the locker device 10 shown in Fig. 2 will be described. Fig. 3 is a diagram showing an example of the mode data 15a, the replenishment method data 15b, and the locker number data 15c shown in Fig. 2.
