Summary of the Invention

Problem to be Solved by the Invention

[0005] By reducing the number of devices constituting the semi-self checkout system, it is possible to reduce costs of the system and a checkout machine and eliminate unnecessary configurations.

[0006] The present invention aims to reduce the cost required for the payment machine and eliminate unnecessary components in a semi-self-service accounting system consisting of a registration machine and a payment machine. [Means for solving the problem]

[0007] To achieve the above objective, the present invention is a semi-self-service accounting system in which a registration machine and a plurality of change dispensers are connected, wherein the registration machine receives product registration operations performed by a first user, registers the products in accordance with the registration operations, and directly transmits transaction information associated with the product registration to the change dispensers, and the change dispensers receive accounting operations performed by a second user different from the first user, and execute accounting processing based on the accounting operations received and the transaction information obtained from the registration machine, thereby forming a semi-self-service accounting system. Here, the semi-self-service accounting system may further include a non-cash payment terminal capable of performing accounting processing using payment methods other than cash, wherein the change dispenser transmits accounting information, which includes at least monetary information indicating the amount of registered goods, to the non-cash payment terminal, and the non-cash payment terminal performs accounting processing based on the monetary information included in the accounting information transmitted from the change dispenser. Furthermore, in a semi-self-service accounting system, the registration machine may directly transmit the transaction information, which includes payment method information identifying the payment method and the amount information, to the change dispenser. The change dispenser may, if the payment method information included in the transaction information obtained from the registration machine specifies cash payment as the payment method, perform accounting processing based on the amount information included in the transaction information. If the payment method information specifies payment by means other than cash, the change dispenser may transmit the accounting information, which includes the amount information, to the non-cash payment terminal. Furthermore, the change dispenser may be configured to notify the first user when it receives an input request from the second user to change the payment method. Furthermore, the change dispenser may be configured to transmit the received request for a change in the payment method to the registration machine. Furthermore, the change dispenser may be equipped with a display unit that displays information, and the display unit may be configured to display support information that assists in the operation of making a payment using the non-cash payment terminal. Furthermore, the semi-self-service accounting system may also be configured to include a printing device, wherein the change dispenser transmits information to the registration device indicating that the accounting process has been completed, and when the registration device receives information from the change dispenser indicating that the accounting process has been completed, it transmits printable information for the transaction related to the accounting process to the printing device, and the printing device prints out a receipt based on the printable information obtained from the registration device. Furthermore, in a semi-self-service accounting system, when the change dispenser receives input from the second user to select either a receipt format that can be printed by the printing device or a format that cannot be printed, it may transmit selection information indicating the selected receipt format to the registration device. The registration device may then transmit the printing information to the printing device if the selection information obtained from the change dispenser indicates that a format that can be printed by the printing device has been selected. Furthermore, the change dispenser may be configured to notify the first user when it receives input from the second user regarding registration for obtaining benefits granted in connection with a transaction. Furthermore, the change dispenser may be configured to transmit information to the registration machine indicating that an input operation related to the received registration has been performed. Another aspect of the present invention that achieves the above objectives is a registration machine used in a semi-self-service accounting system, which is connected to a plurality of change dispensers that perform accounting processing based on transaction information, and comprises: a receiving means for receiving product registration operations performed by a user; a registration means for registering the products in response to the registration operations; and a transmitting means for directly transmitting transaction information associated with the registration of the products to the change dispensers. In this configuration, the registration machine may be configured such that the receiving means receives an operation to specify the payment method to be used for settling the registered goods along with the registration operation, and the transmitting means transmits the transaction information, which includes payment method information indicating the specified payment method and amount information indicating the amount of the registered goods, to the change dispenser. Furthermore, the registration machine may also be configured to include an acquisition means for acquiring a request to change the payment method identified from the change dispenser, the receiving means for accepting an operation by the user to change the payment method when the acquisition means acquires the request, and the transmitting means for transmitting payment method information indicating the changed payment method to the change dispenser. Furthermore, another aspect of the present invention that achieves the above objectives is a change dispenser comprising: an acquisition means connected to a registration machine for acquiring transaction information from the registration machine, which includes payment means information indicating a payment means to be used for settling registered goods and amount information indicating the amount of registered goods; an acceptance means for receiving operations for accounting processing by a user; and, if cash payment is specified as the payment means in the payment means information included in the transaction information acquired from the registration machine, an execution means for performing accounting processing based on the operations for accounting processing received by the acceptance means and the amount information included in the transaction information. In this case, if the change dispenser is configured to include a transmission means for transmitting the amount information included in the transaction information to a non-cash payment terminal capable of performing accounting processing using non-cash payment methods, when the payment method information included in the transaction information specifies payment by means other than cash. Furthermore, the change dispenser's transmission means may be configured to transmit a message to the registration machine when the receiving means receives an input operation requesting a change in the payment method by the user. [Effects of the Invention]

[0008] According to the present invention, in a semi-self-service accounting system consisting of a registration machine and a payment machine, it is possible to reduce the cost required for the payment machine and eliminate unnecessary components. [Brief explanation of the drawing]

[0009] [Figure 1] This diagram shows the overall configuration of the semi-self-service accounting system according to this embodiment. [Figure 2] This figure shows an example of the appearance of a registered machine. [Figure 3] This figure shows an example of the hardware configuration of a registered machine. [Figure 4] This figure shows an example of the appearance of a payment machine. [Figure 5] This figure shows an example of the hardware configuration of a change dispenser. [Figure 6] This diagram shows the connection relationship between the registration machine and the payment machine. [Figure 7] This diagram shows the connection relationships between devices in a conventional semi-self-service accounting system. [Figure 8] This is a sequence diagram illustrating an example of how a semi-self-service accounting system works. [Figure 9] This figure shows an example of an operation screen displayed on the display device of a change dispenser. [Figure 10] This is a diagram showing a modified version of a semi-self-service accounting system. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described in detail below with reference to the attached drawings. <System Configuration> FIG. 1 is a diagram showing the overall configuration of a semi-self checkout system 10 according to the present embodiment. The semi-self checkout system 10 shown in FIG. 1 is used, for example, for accounting processing in stores of commercial facilities such as convenience stores and supermarkets. In recent years, the introduction of checkout systems in which customers perform accounting processing themselves has been increasing in such stores. As an example of this type of checkout system, there is the semi-self checkout system 10. In the semi-self checkout system 10, a store clerk operates a registration device 100 to register products to be purchased by a customer. Then, the customer operates a settlement device 200 to perform accounting processing. Here, the accounting processing is intended to include processing of paying for products by various payment methods, such as cash settlement, electronic settlement using electronic money, and code settlement using code images such as QR code (registered trademark). Note that a store clerk is an example of a first user. A customer is an example of a second user.

[0011] In the example shown in FIG. 1, the registration device 100 and the settlement device 200 are arranged on a counter C where a store clerk and a customer face each other. The registration device 100 is arranged to be operated from the store clerk side in FIG. 1. The settlement device 200 is arranged to be operated from the customer side in FIG. 1. When purchasing a product, first, the customer places the product on the counter C. Next, the store clerk operates the registration device 100 to register the product placed on the counter C. Then, the customer operates the settlement device 200 to perform accounting processing for the registered product.

[0012] <Configuration of Registration Device 100> FIG. 2 is a diagram showing an example of the external appearance of a registration machine 100. As shown in FIG. 2, the registration machine 100 includes a scanner 110, a first display unit 120, a second display unit 130, and a card reader / writer 140. The scanner 110 is a device that reads a product code attached to a product. The product code is formed of a code image such as a barcode or characters. The scanner 110 is provided with a reading window 111. Inside the reading window 111, a laser light emitting device and a light receiving device (not shown) are provided. A store clerk holds the code image of the product code over the reading window 111, and causes the laser light to irradiate the code image to read the code image. A handheld scanner device (a so-called handy scanner) may also be used as the scanner 110.

[0013] The first display unit 120 is a display device for store clerks. The first display unit 120 has a display surface that displays various types of information. The registration machine 100 is placed on a counter C such that the display surface of the first display unit 120 faces the side where the store clerk is located (the front side in the example shown in FIG. 2). The display surface of the first display unit 120 is configured as a touch panel 121. The first display unit 120 is also provided with operation keys 122. A store clerk can input data and commands to the registration machine 100 by touching the display surface in accordance with an operation screen displayed on the touch panel 121 or pressing the keys 122.

[0014] The second display unit 130 is a display device for customers. The second display unit 130 has a display surface that displays information related to products registered by the registration machine 100. The second display unit 130 is provided on the registration machine 100 so as to face the opposite side from the first display unit 120. Therefore, when the registration machine 100 is placed on the counter C such that the display surface of the first display unit 120 faces the side where the store clerk is located (the front side in the example shown in FIG. 2), the display surface of the second display unit 130 faces the side where the customer is located (the back side in the example shown in FIG. 2).

[0015] The card reader / writer 140 is a device for reading point cards that record point information in point services provided in conjunction with the sale of goods. The card reader / writer 140 reads and writes data to the point card according to the product being sold. The reading and writing of data to the point card is performed by magnetic fields or short-range wireless communication, depending on the method of recording information on the point card.

[0016] In this embodiment of the semi-self-service accounting system 10, processing such as printing receipts and reading card information is performed at the payment machine 200. However, a printer 150 for printing receipts may be provided at the registration machine 100, and receipts may be printed from the printer 150 of the registration machine 100 as needed.

[0017] Figure 3 shows an example of the hardware configuration of the registration device 100. As shown in Figure 3, the registration device 100 includes a processor 101, a storage device 102, a display device 103, and a communication interface 104. Note that each of the devices shown in Figure 3 can be composed of one or more hardware components.

[0018] The processor 101 controls the registration device 100 and performs various processes by executing a program. Specifically, the processor 101 controls the reading of code information by the scanner 110 (as explained with reference to Figure 2) and the display by the first display unit 120 and the second display unit 130. The processor 101 also controls the reading and writing of point cards by the card reader / writer 140 and the printing by the printer 150.

[0019] Furthermore, the processor 101 registers the sold products based on the product codes read by the scanner 110. The processor 101 also accepts data and commands input through the operation of the touch panel 121 and keys 122 of the first display unit 120, and executes processing according to the input data and commands. The processor 101 also communicates data with the payment machine 200 to send and receive various information and commands. In addition, the processor 101 reads and writes data to the storage device 102 as needed when executing these processes.

[0020] For example, a CPU (Central Processing Unit) can be used as the processor 101, but various other processors may also be used. The processor 101 is an example of an acceptance means and an example of a registration means.

[0021] The storage device 102 is a device that stores programs executed by the processor 101, control information for the registration device 100, data used for various processes, processing and control log data, etc. As the storage device 102, for example, semiconductor memory such as RAM (Random Access Memory) or ROM (Read Only Memory), or a magnetic disk device may be used.

[0022] The display device 103 is a device that implements the first display unit 120 and the second display unit 130. For example, a liquid crystal display can be used for the display screen of the display device 103. Although Figure 3 shows a single display device 103, the first display unit 120 and the second display unit 130 may each be configured by separate display devices 103.

[0023] The communication interface 104 is an interface for connecting the registration device 100 and the payment machine 200 in a communicative manner. The connection between the registration device 100 and the payment machine 200 may be a direct connection using a connection cable or a connection via a network. The connection line may be a wired line or a wireless line. The processor 101 and the communication interface 104 are examples of transmission means and examples of acquisition means.

[0024] Furthermore, the registration device 100 is a terminal device (POS terminal) for a so-called POS (Point of Sale) system and is connected to a POS server (not shown) via a communication interface 104. The registration device 100 (processor 101) then registers information about the sold products as management information for the POS server. Communication between the registration device 100 and the external device, the POS server, is carried out via a network, for example, through the communication interface 104 shown in Figure 3.

[0025] <Configuration of Payment Machine 200> Figure 4 shows an example of the appearance of the payment machine 200. As shown in Figure 4, the payment machine 200 is composed of a change dispenser 300, an electronic payment terminal 400, a scanner 500, and a printer 600.

[0026] The change dispenser 300 includes a coin slot 310, a banknote slot 320, a coin dispensing section 330, a banknote dispensing section 340, a display device 350, and an indicator lamp 360. The coin slot 310 is the part into which coins are inserted during customer transactions. The banknote slot 320 is the part into which banknotes are inserted during customer transactions. The coin dispensing section 330 is the part into which coins are dispensed when change is given. The banknote dispensing section 340 is the part into which banknotes are dispensed when change is given.

[0027] The display device 350 is a device that displays information necessary for accounting processing. The information displayed on the display device 350 includes, for example, information such as registered products, amounts, and payment methods. The display screen of the display device 350 is made up of, for example, a liquid crystal display. The display surface of the display device 350 is a touch panel 311. Customers can perform input operations for accounting processing on the change dispenser 300 by touching the display surface according to the operation screen displayed on the touch panel 311. The settlement machine 200 is positioned on the counter C such that the display device 350 of the change dispenser 300 faces the customer's side (the front side in the example shown in Figure 4).

[0028] The notification lamp 360 is a lamp that informs the store clerk of the operating status of the payment machine 200. The notification lamp 360 is located on the top of the change machine 300 and illuminates in a preset color according to the operating status of the payment machine 200. The store clerk can determine the operating status of the payment machine 200 by visually confirming the color of the illumination of the notification lamp 360. The operating status of the payment machine 200 may be, for example, normal operation or an error has occurred.

[0029] The electronic payment terminal 400 is a terminal device for making payments using electronic data instead of cash (electronic payment). The electronic payment terminal 400 is an example of a cashless payment terminal. Payment methods that can be used with the electronic payment terminal 400 include, for example, credit card payments, payments using various electronic money, and code payments using code images such as QR codes. Hereinafter, payment methods that can be used with the electronic payment terminal 400 will be referred to as "cashless payments." Furthermore, the media used in cashless payments, such as credit cards, electronic money cards, and electronic money terminals, will be collectively referred to as "payment media." Electronic money cards include prepaid cards and IC cards. An electronic money terminal is an information terminal capable of data communication for cashless payments, and includes, for example, a smartphone with application software that enables cashless payments installed.

[0030] The scanner 500 is a device for reading various types of code information. For example, the scanner 500 is used to read product codes attached to products. The scanner 500 may also be used to read code information in code payments. The scanner 500, like the scanner 110 of the registration machine 100, is provided with a reading window, and by holding the product's code information over the reading window, a laser beam is shone onto the code image to read the code information. In the configuration shown in Figure 4, a handheld scanner device (a so-called handheld scanner) 510 is also provided. In the following description, this handheld scanner device 510 will also be included as part of the scanner 500.

[0031] The printer 600 is a printing device for printing receipts. After the accounting process is completed at the payment machine 200, the printer 600 prints transaction information such as product names and amounts onto a receipt.

[0032] In this embodiment of the semi-self-service accounting system 10, the reading of point cards and the writing of point data are performed by the registration machine 100. However, the payment machine 200 may also be configured to include a card reader / writer, allowing customers to read and write to their point cards.

[0033] Figure 5 shows an example of the hardware configuration of the change dispenser 300. As shown in Figure 5, the change dispenser 300 includes a processor 301, a storage device 302, a communication interface 303, and a connection interface 304. In addition, as explained with reference to Figure 4, the change dispenser 300 is connected to a display device 350, an alert lamp 360, an electronic payment terminal 400, a scanner 500, and a printer 600. Note that each of the devices of the change dispenser 300 shown in Figure 5 can be composed of one or more hardware components.

[0034] The processor 301 performs various processes, including control and accounting, of each device constituting the change dispenser 300 and the payment machine 200 by executing programs. Specifically, the processor 301 controls the deposit and withdrawal of coins and banknotes in the change dispenser 300. The processor 301 also controls the display on the display device 350 (as explained with reference to Figure 4) and the illumination of the notification lamp 360. Furthermore, the processor 301 controls data reading by the electronic payment terminal 400, code information reading by the scanner 500, and printing by the printer 600.

[0035] Furthermore, the processor 301 performs accounting processing related to the transaction of goods. This accounting processing includes settlement processing for cash and non-cash payments. In conjunction with this accounting processing, the processor 301 sends and receives information with the registration machine 100, sends commands to each device connected to the change dispenser 300, and obtains read information from these devices. In addition, the processor 301 performs data read and write operations to the storage device 302 as needed when executing these operations. Furthermore, in these operations, the processor 301 accepts input of data and commands through the operation of the touch panel 311 of the display device 350.

[0036] For example, a CPU can be used as the processor 301, but various other processors may also be used. The processor 301 is an example of an acceptance means and an example of a processing means.

[0037] The storage device 302 is a device that stores programs executed by the processor 301, control information for each device of the payment machine 200, data used for various processes, processing and control log data, etc. Examples of storage devices 302 include semiconductor memory such as RAM or ROM, and magnetic disk drives.

[0038] The communication interface 303 is an interface for enabling communication between the change dispenser 300 and the registration device 100. The connection between the change dispenser 300 and the registration device 100 may be a direct connection using a connection cable, or it may be a connection via a network. The connection line may be a wired line or a wireless line.

[0039] The connection interface 304 is an interface for connecting the change dispenser 300 with the electronic payment terminal 400 and the scanner 500. The change dispenser 300 and these devices are directly connected, for example, by a connecting cable. The processor 301, the communication interface 303, and the connection interface 304 are examples of transmission means and examples of acquisition means.

[0040] <Connection relationship between registration machine 100 and payment machine 200> Figure 6 shows the connection relationship between the registration machine 100 and the payment machine 200. Figure 7 shows the connection relationship of the equipment in a conventional semi-self-service accounting system. The connection relationship of each piece of equipment in this embodiment will be explained by comparing Figures 6 and 7. Note that in Figures 6 and 7, one payment machine 200 is connected to the registration machine 100, but this is merely for illustrative purposes in the drawings. In an actual semi-self-service accounting system, multiple payment machines 200 may be connected to a single registration machine 100.

[0041] In the semi-self-service accounting system 10 of this embodiment shown in Figure 6, the change dispenser 300 and the printer 600, which are components of the settlement machine 200, are directly connected to the registration machine 100. The other components of the settlement machine 200 (electronic payment terminal 400 and scanner 500) are not directly connected to the registration machine 100, but are connected via the change dispenser 300. The change dispenser 300 communicates directly with the registration machine 100 and exchanges data. In contrast, the electronic payment terminal 400 and scanner 500 exchange data with the registration machine 100 via the change dispenser 300. The printing information for the receipt output by the printer 600 is transmitted directly from the registration machine 100 to the printer 600 without going through the change dispenser 300.

[0042] On the other hand, in the semi-self-service accounting system 20 shown in Figure 7, an information processing device 21 is provided on the payment machine 200, and this information processing device 21 is connected to the registration machine 100. Furthermore, all the devices that make up the payment machine 200 are connected to the information processing device 21. These devices then exchange data with the registration machine 100 via this information processing device 21. The information processing device 21 receives commands and data transmitted from the registration machine 100 and transmits them to one of the following devices depending on their type: the change dispenser 300, the electronic payment terminal 400, the scanner 500, and the printer 600. The information processing device 21 also acquires information from the change dispenser 300, the electronic payment terminal 400, the scanner 500, and the printer 600 and transmits it to the registration machine 100. The information processing device 21 is implemented, for example, by a computer.

[0043] In the payment machine 200, when accounting is performed, communication is made to each device depending on the payment method and the provision of services associated with the sale of goods. For example, if the payment method is cash payment, the change dispenser 300 handles deposits and withdrawals associated with the payment process, and after the payment is completed, the printer 600 prints out a receipt. In this case, in the semi-self-service accounting system 10 shown in Figure 6, commands and information are sent directly from the registration machine 100 to the change dispenser 300 and the printer 600. On the other hand, in the semi-self-service accounting system 20 shown in Figure 7, commands and information are sent from the registration machine 100 to the information processing device 21, and the information processing device 21 sends the commands and information received from the registration machine 100 to the change dispenser 300 and the printer 600.

[0044] Furthermore, if the payment method is cashless, data is read from and written to the payment medium at the electronic payment terminal 400. In this case, in the semi-self-service accounting system 10 shown in Figure 6, commands and information for processing cashless payments are transmitted from the registration machine 100 to the electronic payment terminal 400 via the change dispenser 300. After the payment is completed, commands and information for printing receipts are directly transmitted from the registration machine 100 to the printer 600. On the other hand, in the semi-self-service accounting system 20 shown in Figure 7, commands and information are transmitted from the registration machine 100 to the information processing device 21, which then transmits the commands and information received from the registration machine 100 to the electronic payment terminal 400 and the printer 600.

[0045] Thus, in the semi-self-service accounting system 20 shown in Figure 7, communication between the registration machine 100 and the payment machine 200 is performed via the information processing device 21. In contrast, in the semi-self-service accounting system 10 shown in Figure 6, communication between the registration machine 100 and the payment machine 200 is performed via the change dispenser 300. In other words, in the semi-self-service accounting system 20 shown in Figure 7, the information processing device 21 controls communication to each device of the payment machine 200. In contrast, in the semi-self-service accounting system 10 shown in Figure 6, the change dispenser 300 (more specifically, the processor 301 of the change dispenser 300) controls communication to each device of the payment machine 200.

[0046] In the semi-self-service accounting system 10 shown in Figure 6, the printer 600 is connected to the registration machine 100, not the change dispenser 300. Therefore, the print information recorded on the receipt printed by the printer 600 is transmitted directly from the registration machine 100 to the printer 600 without passing through the change dispenser 300. The receipt printed by the printer 600 records information about the purchased items. This information is the same as the information about the items registered in the registration machine 100. This information about the purchased items can be considered the personal information of the customer who made the purchase. Therefore, in the semi-self-service accounting system 10, from a security (personal information protection) perspective, the print information for the receipt is transmitted directly from the registration machine 100 to the printer 600 without passing through the change dispenser 300.

[0047] Furthermore, if the payment machine 200 is configured to include a card reader / writer, the card reader / writer may be connected directly to the registration machine 100 without going through the change dispenser 300, similar to the printer 600. The information recorded on the point card is points awarded based on the purchase of goods. This information is related to the customer's purchase of goods and can be considered the personal information of the customer who purchased the goods. Therefore, when transmitting information read from the point card to the registration machine 100, or when transmitting information to be written to the point card from the registration machine 100 to the card reader / writer, the system may be configured to transmit directly from the registration machine 100 to the card reader / writer.

[0048] <Operation of Semi-Self-Service Accounting System 10> Figure 8 is a sequence diagram showing an example of the operation of the semi-self-service checkout system 10. During the purchase of goods, the registration machine 100 first accepts input from a store employee (S101). This input involves registering the goods and reading the point card. Specifically, the customer places the items to be purchased on counter C (see Figure 1), and the store employee operates the registration machine 100 to register the items placed on counter C sequentially. Goods are registered by having the scanner 110 of the registration machine 100 read the code image of the product code attached to the goods. Next, the store employee asks the customer to select a payment method and inputs the selected payment method into the registration machine 100. If a non-cash payment method is selected, the type of payment medium used is also specified. Furthermore, if the customer has a point card, the store employee reads the point card data using the card reader / writer 140 and updates the point card data according to the purchase.

[0049] When the store clerk completes the input operation at the registration machine 100, the transaction information associated with the registration of the product is directly transmitted from the registration machine 100 to the change dispenser 300 of the payment machine 200 by the store clerk's operation (S102). The transaction information transmitted from the registration machine 100 to the change dispenser 300 includes, for example, payment method information that identifies the payment method and amount information that indicates the amount of the registered product.

[0050] When the change dispenser 300 receives transaction information from the registration machine 100, it controls the status of each device in the settlement machine 200 and displays the amount of the registered goods on the display device 350 based on the amount information included in the transaction information (S103). The status control of the devices in the settlement machine 200 includes controlling them to a state where accounting processing can be performed using the selected payment method, based on the payment method information included in the transaction information. Specifically, for example, if the selected payment method is cash payment, the change dispenser 300 controls its status to a state where it can accept the insertion of coins and banknotes. If the selected payment method is non-cash payment, the change dispenser 300 controls the status of the electronic payment terminal 400 to a state where it can accept payment using the selected payment medium. The change dispenser 300 also transmits accounting information used for accounting processing to the electronic payment terminal 400. The accounting information includes, for example, the amount information of the registered goods.

[0051] Next, the change dispenser 300 accepts deposits made by the customer (S104). If the selected payment method is cash, the deposit is made to the change dispenser 300 in the form of coins or banknotes. If the selected payment method is non-cash, the deposit operation corresponding to the type of payment medium selected is performed at the electronic payment terminal 400.

[0052] In the case of cash payment, the change dispenser 300 performs accounting processing in response to the deposit operation. Specifically, it calculates whether change is needed and the amount of change based on the registered product price and the deposit amount shown in the amount information. The change dispenser 300 displays the product price, the deposit amount, and the calculated amount of change on the display device 350 (S105). On the other hand, in the case of non-cash payment, the above accounting processing is performed by the electronic payment terminal 400. The electronic payment terminal 400 then transmits the information of the deposit amount and the amount of change obtained through the accounting processing to the change dispenser 300. Based on the information obtained from the electronic payment terminal 400, the change dispenser 300 displays the product price and the deposit amount on the display device 350 (S105).

[0053] The customer confirms the displayed amount and performs an operation to confirm the payment (confirmation operation). The confirmation operation is performed, for example, by touching the confirmation button displayed along with the amount on the display device 350 of the change dispenser 300. The change dispenser 300 receives the confirmation operation from the customer. Upon receiving the confirmation operation, the change dispenser 300 transmits information indicating that the accounting process has been completed to the registration device 100 (S106). The information transmitted to the registration device 100 includes, for example, information on the amounts received and paid related to the accounting process.

[0054] When the registration machine 100 obtains information indicating that the accounting process has been completed, it directly sends a print instruction for a receipt related to this accounting process, along with printable information based on the transaction details in this accounting process, to the printer 600 of the payment machine 200 (S107). The printable information includes, for example, information such as the goods and the price of each item, the payment amount, and the amount of change. When the printer 600 receives the print instruction and printable information, it prints out a receipt based on the printable information (S108).

[0055] <Change of payment method> In the above example, the payment method was entered by a store employee using the registration machine 100. Now, consider a case where a customer wishes to change their payment method when processing their payment at the payment machine 200. For example, they might have selected electronic money payment, but then want to switch to cash payment because they don't have enough money (charged amount) in their electronic money account. In such a case, it would be troublesome to ask a store employee to operate the registration machine 100 to change the payment method. Therefore, it would be better to configure the payment machine 200 to accept changes in the payment method.

[0056] When the payment machine 200 accepts a change of payment method, it accepts the change of payment method operation via an operation screen displayed on the display device 350 of the change dispenser 300. When the change of payment method operation is performed, the change dispenser 300 transmits a request for change of payment method to the registration machine 100. When the registration machine 100 receives the request for change of payment method, it notifies the store clerk of this fact and makes it possible to accept the change of payment method operation. The notification is performed, for example, by displaying a message on the first display unit 120 of the registration machine 100 or by outputting an audio signal. Alternatively, the notification may be performed by displaying a message on the display device 350 of the payment machine 200.

[0057] The store clerk, for example, operates the operation screen displayed on the first display unit 120 to change the payment method according to the customer's request. When the payment method is changed, the registration machine 100 sends transaction information, which includes the changed payment method information, to the settlement machine 200. The change dispenser 300 of the settlement machine 200 controls the state of the change dispenser 300 or the electronic payment terminal 400 according to the changed payment method indicated in the payment method information, and performs the accounting process.

[0058] <Display screen of the display device 350 of the change dispenser 300> Figure 9 shows an example of an operation screen displayed on the display device 350 of the change dispenser 300. Customers refer to this operation screen to perform accounting procedures. Specifically, if a customer has selected cash payment as their payment method, the operation screen shown in Figure 9 is provided with an amount display unit 351, a message display unit 352, a point card button 353, a first change button 354, and a second change button 355.

[0059] The amount display unit 351 displays the amount (account amount) of the product registered in the registration machine 100. The message display unit 352 displays various messages related to the accounting process. In the example shown in Figure 9, the message display unit 352 displays a text message indicating support information (guidance) to assist in the payment operation using the selected payment method.

[0060] The point card button 353 is a button object used to instruct the store to process the point card. When a customer touches the point card button 353, the store becomes able to accept the use of points recorded on the point card when purchasing goods. When using points on a point card, if the payment machine 200 is equipped with a card reader / writer, the customer can have the information recorded on the point card read by this card reader / writer. If the payment machine 200 is not equipped with a card reader / writer, the customer hands the point card to the store clerk. The store clerk receives the point card from the customer and can have the information recorded on the point card read by the card reader / writer 140.

[0061] The first change button 354 is a button object for changing the payment method. The first change button 354 is a button for changing from non-cash payment to cash payment. Changing from non-cash payment to cash payment is done, for example, when a customer has selected to pay with electronic money, but the amount deposited (charged amount) to the electronic money is insufficient, and they want to switch to cash payment. In this case, when the customer touches the first change button 354 on the operation screen, a request to change the payment method is sent from the change machine 300 to the registration machine 100. When the registration machine 100 receives the request to change the payment method, it notifies the store clerk of this fact. The notification is done, for example, by displaying it on the first display unit 120 of the registration machine. The store clerk can change the payment method according to the customer's request by operating the registration machine 100.

[0062] The second change button 355 is a button object for changing the payment method. The second change button 355 is a button for changing from cash payment to cashless payment. Changing from cash payment to cashless payment is done, for example, when a customer has selected to pay with cash, but the change they will receive will be too small, so they want to switch to payment with electronic money such as a credit card. In this case, when the customer touches the second change button 355 on the operation screen, a request to change the payment method is sent from the change machine 300 to the registration machine 100. When the registration machine 100 receives the request to change the payment method, it notifies the store clerk of this fact. The notification is done, for example, by displaying it on the first display unit 120 of the registration machine. The store clerk can change the payment method according to the customer's request by operating the registration machine 100.

[0063] As described above, the operation screen shown in Figure 9 is provided with two button objects for changing the payment method: a first change button 354 and a second change button 355. The second change button 355 is displayed as a smaller button compared to the first change button 354. This is to make it psychologically difficult for customers to select the second change button 355. Depending on the product, payment by a specific method such as credit card may be difficult due to additional conditions such as services. Therefore, the second change button 355, which requests a change from cash payment to non-cash payment, is made less conspicuous than the first change button 354, which requests a change from non-cash payment to cash payment.

[0064] In the example above, when the first change button 354 is selected, the change dispenser 300 communicates with the registration machine 100, and the registration machine 100 changes the payment method. Alternatively, the change dispenser 300 may change the payment method. In this case, for example, when a customer touches the first change button 354 on the operation screen, the change dispenser 300 enters a standby state without sending a request to the registration machine 100 to change the payment method. The display on the change dispenser 300's display device 350 then switches to a screen prompting the customer to insert cash for cash payment. Next, when the cash is inserted by the customer and the cash payment transaction is completed, the change dispenser 300 sends a notification to the registration machine 100 informing it that the cash payment has been completed.

[0065] <Variation> Figure 10 shows a modified example of the semi-self-service accounting system 10. Figure 10 shows the connection relationship between the registration machine 100 and the settlement machine 200 in the modified example of the semi-self-service accounting system 10. In this modified example, the display device 350 in the settlement machine 200 is provided as a separate device from the change dispenser 300. In addition to the configuration in which the change dispenser 300 and the display device 350 are integrated, the settlement machine 200 can also adopt a configuration in which an information processing device having a display screen such as a tablet terminal is used as the display device 350. In such a configuration, the display device 350 is equipped with data processing functions and communication functions and can be used as a communication control means in the settlement machine 200 on its own.

[0066] Although not specifically illustrated, the display device 350, which can perform communication control and data processing independently as described above, comprises a processor, a storage device, a display unit, a communication interface, and a connection interface. The processor performs communication control between the registration machine 100 and the payment machine 200, as well as display control on the display unit, by executing a program. For example, a CPU is used as the processor 101. The storage device stores the program executed by the processor, control information for each device of the payment machine 200, data used for various processes, and processing and control log data. For example, semiconductor memory such as RAM or ROM is used as the storage device. The display unit is composed of, for example, a liquid crystal display. The communication interface is an interface for connecting the display device 350 and the registration machine 100 so that they can communicate with each other. The connection interface is an interface for connecting the display device 350 with the change machine 300, the electronic payment terminal 400, and the scanner 500.

[0067] In the semi-self-service accounting system 10 shown in Figure 10, the display device 350 and printer 600, which are components of the payment machine 200, are connected to the registration machine 100. The other components of the payment machine 200 (change dispenser 300, electronic payment terminal 400, and scanner 500) are not directly connected to the registration machine 100, but are connected via the display device 350. The change dispenser 300, electronic payment terminal 400, and scanner 500 exchange data with the registration machine 100, in principle, via the display device 350. However, the printing information for receipts printed by the printer 600 is sent directly from the registration machine 100 to the printer 600, without going through the change dispenser 300.

[0068] In the accounting process, when cash payments are made, the semi-self-service accounting system 10 shown in Figure 10 transmits commands and information directly from the registration device 100 to the display device 350 and printer 600. When non-cash payments are made, the semi-self-service accounting system 10 shown in Figure 10 transmits commands and information for processing non-cash payments from the registration device 100 to the electronic payment terminal 400 via the display device 350.

[0069] After accounting processing, if a cash payment is made, the semi-self-service accounting system 10 shown in Figure 10 transmits settlement information related to the accounting process from the change dispenser 300 to the registration machine 100. This settlement information includes the amount received and the amount of change dispensed. If a non-cash payment is made, the semi-self-service accounting system 10 shown in Figure 10 transmits settlement information related to the accounting process from the electronic payment terminal 400 to the registration machine 100 via the display device 350. After the settlement is completed, the registration machine 100 directly transmits instructions and information for printing receipts to the printer 600.

[0070] As described above, in the semi-self-service accounting system 10 shown in Figure 10, communication between the registration machine 100 and the payment machine 200 is conducted via the display device 350. In other words, in the semi-self-service accounting system 10 shown in Figure 10, the display device 350 controls the communication between the devices of the payment machine 200.

[0071] Although embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above embodiments. For example, in the embodiments shown in Figures 6 and 10, the printer 600 in the payment machine 200 is directly connected to the registration machine 100 without the need for other devices. In contrast, the operation of the printer 600 may be controlled by the change dispenser 300 (in the case of Figure 6) or the display device 350 (in the case of Figure 10), and only the print information to be printed on the receipt may be transmitted from the registration machine 100 to the printer 600.

[0072] Furthermore, in the embodiments shown in Figures 6 and 10, the electronic payment terminal 400 is connected to the registration device 100 via a change dispenser 300 (in the case of Figure 6) or a display device 350 (in the case of Figure 10). In contrast, some information, including personal information such as authentication information, may be transmitted directly from the electronic payment terminal 400 to the registration device 100.

[0073] Furthermore, in the above embodiment, the printer 600 of the payment machine 200 is configured to print receipts, but the printer 600 may also be configured to print other printed materials such as receipts and coupons. Also, the receipt is not limited to being printed, but may also be transmitted as electronic data to a management server or customer communication terminal. Moreover, the system may be configured to allow selection between issuing receipts in a format that can be printed by the printer 600 and receipts in a format that cannot be printed by the printer 600 (for example, handwritten receipts; hereinafter simply referred to as "receipts").

[0074] If the customer can choose between a receipt and a receipt, for example, before printing a receipt, the change dispenser 300 displays an operation screen on the display device 350 for selecting between a receipt and a receipt. When the change dispenser 300 receives a selection operation on the display device 350, it sends information to the registration device 100 indicating whether a receipt or a receipt was selected. If the transmitted information indicates that a receipt has been selected, the registration device 100 sends the print information directly to the printer 600, as shown in S107 of Figure 8.

[0075] On the other hand, if the transmitted information is information for selecting a receipt, the registration device 100 notifies the store clerk that a receipt has been selected. This notification is made, for example, by displaying a message on the first display unit 120 or by outputting an audio message. In this case, the registration device 100 does not send print instructions or print information to the printer 600, and the store clerk manually creates the receipt and hands it to the customer.

[0076] Furthermore, in the above embodiment, the store clerk operates the registration machine 100 to register products, and the customer operates the payment machine 200 to perform accounting. However, this semi-self-service accounting system 10 may also be configured to handle processes other than accounting. For example, a store may offer a service that provides benefits to registered customers in connection with their transactions. In such a case, customer registration for obtaining benefits may be performed in the semi-self-service accounting system 10. In this case, for example, an operating mode may be provided in the change dispenser 300 for processing customer registration, and in this operating mode, the change dispenser 300 displays an operation screen for customer registration on the display device 350. When the customer inputs the information necessary for registration and the change dispenser 300 receives this input, the change dispenser 300 transmits information to the registration machine 100 indicating that it has received the input operation for registration (hereinafter referred to as "registration request"). The registration machine 100 then notifies the store clerk that it has received the registration request. Notification is provided, for example, by displaying a message on the first display unit 120 or by outputting an audio message. Alternatively, notification may be provided by displaying a message on the display device 350 of the payment machine 200.

[0077] In addition, various modifications and substitutions of configurations that do not depart from the technical concept of the present invention are included in the present invention. [Explanation of symbols]
