Description

[Technical Field]

[0001] The present invention relates to a settlement device and a program. [Background technology]

[0002] There is known a POS system that is configured with a registration device where products are registered and a settlement device where the payment for the products registered by the registration device is separated (see, for example, Patent Document 1). In such a POS system, a store clerk registers the products purchased by a customer using the registration device, and the customer can then settle the payment for their purchases at the settlement device. This, for example, saves labor by automating the process of receiving product payments and shortens the time from registering the purchased products to completing the payment. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5803121 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology described in Patent Document 1, if there is no store clerk to operate the registration device, the corresponding settlement device will not be used. As a result, there may be times when the settlement device cannot be used, and the settlement device is not always being used effectively.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a POS system, a settlement device, and a program that can effectively utilize the settlement device in a POS system that has a registration device and a settlement device. [Means for solving the problem]

[0006] One aspect of the present invention that solves the above-mentioned problems is a POS system that includes a registration device in which a store clerk registers items purchased by a customer, and a settlement device, wherein the settlement device has two operating modes: a semi-self-service mode in which the customer pays for the items registered in the registration device, and a full-self-service mode in which the customer registers and pays for the items they have purchased, and is equipped with a mode change means that can switch the operating mode between the semi-self-service mode and the full-self-service mode, the registration device has a key that accepts operations to switch the operating mode of the settlement device, and the mode change means switches from the semi-self-service mode to the full-self-service mode based on operation of the key.

[0007] In addition, in the above-mentioned POS system, the settlement device may further include a reading unit that reads code information, and the mode change means may switch the operating mode to full self-service mode when the reading unit reads the code information attached to the product.

[0008] In the above POS system, the mode change means may switch the operation mode to a full self-service mode when the registration device corresponding to the settlement device is out of operation.

[0009] In the above POS system, the mode change means may be configured to operate in the semi-self-service mode when it reads information used in the semi-self-service mode, even when the POS system is operating in the full-self-service mode.

[0010] Another aspect of the present invention is a settlement device included in a POS system that has a registration device in which a store clerk registers items purchased by customers and a settlement device, and the settlement device has two operating modes: a semi-self-service mode in which customers pay for items registered in the registration device, and a full-self-service mode in which customers register and pay for their purchases, and is equipped with a mode change means that can switch the operating mode between the semi-self-service mode and the full-self-service mode, and the mode change means switches from the semi-self-service mode to the full-self-service mode based on operation of a key provided on the registration device that accepts operation to switch the operating mode of the settlement device.

[0011] Another aspect of the present invention is a program for causing a computer serving as a settlement device included in a POS system equipped with a registration device in which a store clerk registers items purchased by customers and a settlement device to operate in two operating modes: a semi-self-service mode in which customers pay for items registered in the registration device, and a full-self-service mode in which customers register and pay for the items they have purchased; and a step of switching the operating mode between the semi-self-service mode and the full-self-service mode, wherein in the switching step, the program switches from the semi-self-service mode to the full-self-service mode based on operation of a key provided on the registration device that accepts operation to switch the operating mode of the settlement device. [Effects of the Invention]

[0012] According to the present invention, in a POS system equipped with a registration device and a settlement device, the settlement device can be effectively utilized. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows an example of the configuration of a POS (Point Of Sales) system according to this embodiment. The POS system shown in the figure includes a store controller 10, a registration device 20, and three payment devices 30. The store controller 10, the registration device 20, and the three payment devices 30 are connected via a wired or wireless LAN (Local Area Network) 11 so as to be able to communicate with each other.

[0015] The configuration of the POS system shown in the figure is an example. For example, the POS system may include two or more registration devices 20, or two or less or four or more payment devices 30. The POS system may also be configured not to include a store controller 10. If the POS system is configured not to include a store controller 10, another device (for example, a registration device 20, or if there are two or more registration devices 20, a representative registration device 20) may also function as the store controller 10.

[0016] The store controller 10 is a computer that controls the POS system and manages various information such as a product master. The store controller 10 appropriately transmits the latest product master to the registration device 20 and each checkout device 30. The product master is a file that stores product information such as product identification information (e.g., JAN code), product name (product name, item name), sales price, and discount information for each product. The store controller 10 obtains the product master reflecting the latest product information from an external source (e.g., a server at headquarters, a medium such as a CD-ROM), and transmits it appropriately to the registration device 20 and each checkout device 30.

[0017] The registration device 20 executes a registration process to register a product to be purchased. Product registration is performed, for example, by using a scanner to read a barcode attached to the product or by operating a preset button or the like displayed on a product registration screen. The registration device 20 also generates and stores information about the registered product (hereinafter referred to as registration data).

[0018] The registration data includes registration data identification information for identifying the registration data, the registration date and time, product identification information for each registered product, the product name, sales price, discount information, the transaction number (purchase number) indicating the number of products to be purchased, and the total amount (total price) of the products to be purchased. The registration data may further include registration device identification information for identifying the registration device 20 that generated the registration data (i.e., the registration device 20 that registered the products related to the registration data).

[0019] The registered data is used for the settlement process in the settlement device 30. The settlement process is a process in which the price of the registered product is paid and settled selectively using cash, electronic money (including the charge balance of a prepaid card), credit card, etc.

[0020] In this embodiment, there are multiple settlement devices 30, and one of the multiple settlement devices executes the settlement process using the registration data generated in the registration device 20. One way to specify which of the multiple settlement devices 30 should execute the settlement process is for a store clerk to specify the settlement device 30 that should execute the settlement process using the registration device 20. That is, the store clerk specifies which of the multiple settlement devices 30 should execute the settlement process by performing an operation to specify the settlement device 30 on the registration device 20. The registration device 20 may be configured to display operating information indicating the operating status of each settlement device 30, so that the operating status of each settlement device 30 can be checked on the registration device 20 when the store clerk specifies the settlement device 30.

[0021] When a store clerk designates one settlement device 30, the registration data generated in the registration device 20 is transmitted to the designated settlement device 30 via the LAN 11. That is, when a settlement device 30 is designated following the registration process, the registration device 20 transmits the registration data based on the registration process to the designated settlement device 30. Note that in this embodiment, the registration device 20 transmits the registration data directly to the settlement device 30, but the registration data may also be transmitted to the settlement device 30 via the store controller 10.

[0022] The checkout device 30 has two operating modes: a semi-self-service mode in which a store clerk registers the items a customer purchases on a registration device and the customer then pays for the registered items on the checkout device; and a full-self-service mode in which the customer registers the purchased items on the checkout device and then pays for them. In semi-self-service mode, the checkout device 30 executes the checkout process for the items registered on the registration device in response to the customer's operation. That is, the checkout device 30 executes the checkout process based on the registration data received from the registration device 20. Furthermore, when the checkout process is completed in semi-self-service mode, the checkout device 30 notifies the registration device 20 of the completion of the checkout process. On the other hand, in full-self-service mode, the checkout device 30 executes the registration process to register the items to be purchased in response to the customer's operation, and then executes the checkout process for the registered items.

[0023] Next, configuration examples of the registration device 20 and the settlement device 30 will be described with reference to Figs. 2 to 5. Fig. 2 is a block diagram showing a configuration example of the registration device 20. Fig. 3 is a block diagram showing a configuration example of the settlement device 30. Fig. 4 is a perspective view showing an external appearance example of the registration device 20 and the settlement device 30. Fig. 5 is a perspective view showing an external appearance example of the settlement device 30.

[0024] As shown in FIG. 2, the registration device 20 includes a CPU (Central Processing Unit). The device includes a memory (ROM) 201, a read-only memory (ROM) 202, a random access memory (RAM) 203, a scanner unit 204, a display unit (for store clerks) 205, a display unit (for customers) 205a, an operation unit 206, a communication unit 207, a buzzer 208, and a printing unit 209. These can communicate with each other via a bus.

[0025] The CPU 201 is a central processing unit that controls the operation of the registration device 20 by reading and executing a program stored in the ROM 202 . The ROM 202 is a read-only memory that stores various types of information used by the CPU 201, including programs.

[0026] The RAM 203 is a read / write memory that can be read and written at any time, and stores various information. For example, the RAM 203 stores product master data acquired from the store controller 10, registration data generated after the registration process, and information about the settlement device 30 that executes the settlement process. The RAM 203 may also store operation information received from the settlement device 30. The scanner unit 204 optically reads the barcode (product code) attached to the product.

[0027] Display unit (for store clerk) 205 is a touch panel (for example, a liquid crystal touch panel) that displays various information for store clerks. For example, display unit (for store clerk) 205 displays a product registration screen on which preset buttons associated with product information (product code, etc.) are arranged.

[0028] Display unit (for customers) 205a displays various information for customers. For example, display unit (for customers) 205a displays the prices of registered products, etc. Display unit (for customers) 205a may be a touch panel (for example, a liquid crystal touch panel).

[0029] The operation unit 206 has various operation buttons (subtotal key, current total key, number input key, correction key, preset key, etc.) for operating the registration device 20. For example, when an operation button (preset key) is operated, the operation unit 206 accepts an operation input regarding product information (product code, etc.) that is set and registered in advance in that preset key.

[0030] The communication unit 207 communicates with other devices via the LAN 11 . The buzzer 208 generates a buzzer sound when it is necessary for a store clerk to confirm an operation. The printing unit 209 prints and issues media as necessary. For example, the printing unit 209 may print information guiding the cashier 30 designated by the store clerk.

[0031] In FIG. 4, the external configuration of a scanner unit 204, a display unit (for store clerks) 205, an operation unit 206, and a printing unit 209 is shown.

[0032] 3, the settlement device 30 includes a CPU 301, a ROM 302, a RAM 303, a scanner unit 304, a display unit 305, an operation unit 306, a communication unit 307, a buzzer 308, a printing unit 309, a settlement unit 310, a sign pole 311, a human detection sensor 312, and a scale connection unit 313. These can communicate with each other via a bus.

[0033] The CPU 301 is a central processing unit that controls the operation of the settlement device 30 by reading and executing programs stored in the ROM 302 . The ROM 302 is a read-only memory that stores various types of information used by the CPU 301, including programs.

[0034] The RAM 303 is a memory that can be read and written at any time and stores various information, such as a product master acquired from the store controller 10 and registration data acquired from the registration device 20. The scanner unit 304 optically reads, for example, a barcode (product code) attached to a product or a barcode (membership code) attached to a membership card or the like.

[0035] Display unit 305 is a touch panel (for example, a liquid crystal touch panel) and displays various information. For example, display unit 305 displays a settlement screen on which the total amount and the like are displayed.

[0036] The operation unit 306 includes various operation buttons (such as a correction key and a preset key) for operating the settlement device 30. For example, the operation unit 306 accepts corrections to operation inputs when an operation button (correction key) is operated.

[0037] The communication unit 307 communicates with other devices via the LAN 11 . When an error or the like occurs, the buzzer 308 generates a buzzer sound to notify the user of the error. The printing unit 309 prints and issues media. For example, when the payment process (i.e., payment of the purchase price of the merchandise) is completed, the printing unit 309 prints and issues a receipt indicating the payment result to be taken home by the customer.

[0038] The settlement unit 310 is configured to include a change dispenser, a credit card reader, an electronic money reader, etc., and their respective control units, and settlement processing is performed using the settlement unit 310 with cash, credit, electronic money, etc. The settlement unit 310 executes settlement with cash using the change dispenser, and outputs the result of the settlement (for example, information indicating whether the settlement has been completed) to the CPU 301 via the bus. The change dispenser is equipped with a banknote slot for inserting and ejecting banknotes, a coin slot for inserting coins, and a change ejection port for ejecting change. In the following explanation, the banknote slot and coin slot may be collectively referred to as the coin slot. The settlement unit 310 also executes a settlement using credit and outputs the result of the settlement via the port and the bus to the CPU 301. The settlement unit 310 also executes a settlement using electronic money and outputs the result of the settlement to the CPU 301 via the bus.

[0039] The sign pole 311 has indicator lights of multiple colors, and by turning on or flashing these indicator lights, it notifies the user that the settlement device 30 is the device designated by the store clerk or that it can be operated. The human detection sensor 312 is a sensor that detects the presence of a person (customer) within a predetermined range in front of the settlement device 30.

[0040] The scale connection unit 313 connects to and communicates with the scale 50. The scale 50 is a scale for measuring the weight of products, which is used to prevent fraud when registering products purchased by customers in full self-service mode.

[0041] FIG. 5 shows the external configuration of the scanner unit 304, display unit 305, payment unit 310, sign pole 311, and the like.

[0042] 6 and 7 are examples of screens displayed on the settlement device 30. In semi-self-service mode, the settlement device 30 executes a settlement process for products registered in the registration device 20. That is, when the settlement device 30 is in semi-self-service mode, a store clerk registers products in the registration device 20, and the customer operates the settlement device 30 to settle the payment for the products registered in the registration device 20. In addition, in full-self-service mode, the settlement device 30 executes a registration process for products and a settlement process for the registered products. That is, when the settlement device 30 is in full-self-service mode, the customer operates the settlement device 30 to register products and settle the payment for the registered products.

[0043] The settlement device 30 normally operates in semi-self-service mode. The CPU 301 (mode change means) of the settlement device 30 can switch the operation mode between semi-self-service mode and full-self-service mode. For example, the CPU 301 switches the operation mode from semi-self-service mode to full-self-service mode when a predetermined condition is met. The predetermined condition may be, for example, that the scanner unit 304 has read code information attached to a product. In this case, the CPU 301 switches the operation mode to full-self-service mode when the scanner unit 304 has read the code information attached to the product. The CPU 301 then switches the operation mode to semi-self-service mode when the settlement process is completed. Alternatively, the CPU 301 may switch the operation mode to semi-self-service mode when registration data is received from the registration device 20. Alternatively, the CPU 301 may switch the operation mode to semi-self-service mode when a predetermined operation is performed.

[0044] Another example of the predetermined condition is when a predetermined time period has arrived. In this case, the CPU 301 switches the operation mode to full self-service mode when a predetermined time period (time) has arrived, and switches the operation mode to semi-self-service mode when the time period has passed. Another example of the predetermined condition is when the registration device 20 configured to correspond to the settlement device 30 is out of operation. In this case, the CPU 301 switches the operation mode to full self-service mode when the corresponding registration device 20 is out of operation, and switches the operation mode to semi-self-service mode when the corresponding registration device is in operation. A corresponding registration device 20 is pre-configured in the settlement device 30, and the settlement device 30 receives registration data from the corresponding registration device 20. The CPU 301 acquires the operation status of the corresponding registration device 20 from the corresponding registration device 20 or the store controller 10. Alternatively, the CPU 301 may determine that the corresponding registration device 20 is out of operation if it has not received registration data for a predetermined time period or longer, and determine that the corresponding registration device 20 is in operation if it receives registration data.

[0045] In semi-selfie mode, the settlement device 30 first displays a settlement screen 600, as shown in Fig. 6, on the display unit 305. The settlement screen 600 shown in this figure displays the number of items registered in the registration device 20, "2 items" 601, the total amount, "276 yen" 602, a message prompting the customer to select a payment method, "Cash and credit cards are accepted. Please press the button on the right to select your payment method" 603, a cash button 604 to select cash payment, and a credit button 605 to select credit payment. The customer presses the cash button 604 or the credit button 605 to select a payment method and settle the payment for the items.

[0046] Furthermore, in full self-service mode, the payment device 30 first displays a registration start screen 700 as shown in FIG. 7 on the display unit 305. The registration start screen 700 displays a message prompting the customer to register products, "Select a button to start registration" 701, as well as a plastic bag start button 702 for registering using a plastic bag, and a my bag start button 703 for registering using a my bag. The customer presses the plastic bag start button 702 or the my bag start button 703, and then registers the products. Once product registration is complete, the payment device 30 displays the payment screen 600 on the display unit 305 and executes the payment process.

[0047] Furthermore, the settlement device 30 may display whether the current operation mode is the semi-full mode or the full self-service mode on the display unit 305. This allows the user to know in which operation mode the settlement device 30 is operating.

[0048] Furthermore, the settlement device 30 may light up the sign pole 311 in different colors depending on the operation mode. For example, the settlement device 30 lights up the sign pole 311 in green when in semi-self-service mode, and lights up the sign pole 311 in red when in full-self-service mode. This makes it possible to check the operation mode of the settlement device 30 by the color of the sign pole 311. This saves the trouble of checking the display unit 305 of the settlement device 30, and also makes it possible to know the operation mode of the settlement device 30 from a distance.

[0049] Next, an example of the process transition of the settlement device 30 of this embodiment will be described with reference to the flowcharts of Figures 8 and 9. In the initial state, the settlement device 30 is in a standby state. In the standby state, the settlement device 30 is waiting for the customer to start an operation. In the standby state, a standby screen is displayed on the display unit 305 of the settlement device 30. Here, in response to the customer starting an operation, the settlement device 30 executes the process shown in Figure 8.

[0050] (Step S101) CPU 301 determines whether the operating mode is semi-self mode. If CPU 301 determines that the operating mode is semi-self mode, the process proceeds to step S102. If CPU 301 determines that the operating mode is full-self mode, the process proceeds to step S111.

[0051] (Step S102) The CPU 301 reads out the registration data previously received from the registration device 20 and stored in the RAM 303, and displays the settlement screen 600 on the display unit 305 based on the read registration data. Then, the process proceeds to step S103. (Step S103) The CPU 301 executes the settlement process based on the read registration data. Then, the CPU 301 transmits settlement completion information indicating that the settlement process has been completed to the registration device 20 that transmitted the registration data via the communication unit 307. Then, the process ends.

[0052] (Step S111) CPU 301 displays registration start screen 700 on display unit 305 and executes registration processing to register products in response to a registration operation. When the customer has finished registering the purchased products, he or she operates the subtotal key. When the subtotal key accepts input, CPU 301 ends the registration processing. Then, the process proceeds to step S112. (Step S112) The CPU 301 executes the payment process for the product registered in step S111, and then ends the process.

[0053] Furthermore, the settlement device 30 executes the process shown in FIG. 9 when in a standby state in the semi-self mode. (Step S201) CPU 301 determines whether the above-mentioned predetermined conditions are met. If CPU 301 determines that the predetermined conditions are met, it proceeds to the processing of step S202. On the other hand, if CPU 301 determines that the predetermined conditions are not met, it executes the processing of step S201 again.

[0054] (Step S202) The CPU 301 determines whether or not the scale 50 is connected to the scale connection unit 313. If the CPU 301 determines that the scale 50 is connected, the process proceeds to step S204. If the CPU 301 determines that the scale 50 is not connected, the process proceeds to step S203.

[0055] (Step S203) The CPU 301 blinks the sign pole 311 and sends an alert to the registration device 20 via the communication unit 307 notifying that the scale 50 is not connected, and outputs an error indicating that the scale 50 is not connected. Upon receiving the alert, the registration device 20 displays a message indicating that the scale 50 is not connected. Then, the process returns to step S201.

[0056] (Step S204) The CPU 301 determines whether or not all of the registered data received from the registration device 20 has been settled. If the CPU 301 determines that all of the registered data has been settled, the process proceeds to step S205. If the CPU 301 determines that there is registered data that has not been settled, the CPU 301 executes the process of step S204 again.

[0057] (Step S205) CPU 301 switches the operation mode to the full self mode, and then ends the process.

[0058] In addition, when the settlement device 30 is in standby mode in full self-service mode, if the above-mentioned predetermined conditions are no longer satisfied, the settlement device 30 may switch the operation mode from full self-service mode to semi-self-service mode.

[0059] As described above, the POS system of this embodiment is a POS system equipped with a registration device 20 in which a store clerk registers the items purchased by a customer, and a settlement device 30. The settlement device 30 has two operating modes: a semi-self-service mode in which the customer settles for the items registered in the registration device, and a full-self-service mode in which the customer registers and settles for the items they have purchased, and is equipped with a mode change means that can switch the operating mode between the semi-self-service mode and the full-self-service mode.

[0060] According to the above configuration, the payment device can be used as a self-service payment machine where customers can register and pay for products. Therefore, even if there is no store clerk to operate the registration device, the payment device can be used, allowing for effective use of the payment device.

[0061] Furthermore, in the POS system of this embodiment, the settlement device 30 further includes a scanner unit 304 that reads code information, and the mode change means switches the operating mode to full self-service mode when the scanner unit 304 reads the code information attached to the product. According to the above configuration, the settlement device 30 can be placed in full self-service mode by performing a registration operation in which the scanner unit 304 reads the code information attached to the product, so that the settlement device 30 can be easily switched to full self-service mode.

[0062] In the POS system of this embodiment, the mode change means switches the operation mode to full self-service mode when a predetermined time arrives. With the above configuration, the settlement device 30 automatically enters full self-service mode at the predetermined time, so that the settlement device 30 can be easily switched to full self-service mode.

[0063] Furthermore, in the POS system of this embodiment, the mode change means switches the operating mode to full self-service mode when the registration device 20 corresponding to the settlement device 30 is out of operation. According to the above configuration, when the registration device 20 is out of operation, the settlement device 30 goes into full self-service mode, so that the settlement device 30 can be used when there is no store clerk to operate the registration device 20 (when the registration device 20 is unmanned), and the settlement device 30 can be used effectively.

[0064] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and includes designs within the scope of the gist of the present invention.

[0065] For example, in the above-described embodiment, the checkout device 30 switches its operating mode to semi-self-service mode when a predetermined condition is met, but the method of switching the operating mode is not limited to this. For example, the checkout device 30 may switch its operating mode when the scanner unit 304 reads a barcode (clerk code) attached to a clerk card held by a clerk. Alternatively, the checkout device 30 may switch its operating mode in response to an instruction from the registration device 20 or the store controller 10.

[0066] For example, when switching the operation mode in response to an instruction from the registration device 20, an operation mode switching button for accepting an instruction to switch the operation mode of the settlement device 30 may be displayed on the registration screen of the registration device 20.

[0067] Fig. 10 is a diagram showing an example of a registration screen when an operation mode switching button is displayed. The registration device 20 displays a registration screen such as that shown in Fig. 10 on the display unit (for store clerk) 205. In addition to preset buttons (buttons displaying "strawberry," "apple," etc.) associated with product information (product code, etc.), the registration screen shown in Fig. 10 also includes a payment machine designation button 501 (buttons displaying "payment machine 1," "payment machine 2," or "payment machine 3") for designating the payment machine 30 that will execute the payment process (i.e., the payment machine 30 that will send the registration data), a receipt button 503 for printing a receipt, an unsettled list button 502 for displaying an unsettled list screen, and an operation mode switching button 504 for switching the operation mode of the payment machine 30.

[0068] In the above example, since there are three settlement devices 30 in the POS system 1, three settlement device designation buttons 501 are provided, corresponding to each of the three devices: settlement device 1, settlement device 2, and settlement device 3.

[0069] In addition, in the illustrated example, each settlement machine designation button 501 displays the status (condition, operating mode, etc.) of the corresponding settlement machine. Specifically, the status of the corresponding settlement machine is displayed as a badge on each button. For example, in the illustrated example, the button for settlement machine 1 displays a badge with "full self-service," the button for settlement machine 2 displays a badge with "offline," and the button for settlement machine 3 displays a badge with "semi-self-service." "Offline" indicates that the settlement device 30 corresponding to the button is offline or that the power to the settlement device 30 corresponding to the button is not turned on.

[0070] The display position of the badge is not limited to the display position shown in Fig. 10 (where a part of the badge is displayed outside (above) the display area of ​​the button), but may be a display position where the entire badge fits within the display area of ​​the button. Also, the display of the status is not limited to a badge, but a text display area for displaying a statement (text) indicating the status may be provided within the button, and the status may be displayed in that display area. Also, the color of the button may be changed depending on the status.

[0071] Furthermore, by operating the operation mode switching button 504, the operation mode of the settlement device 30 can be switched from the registration device 20. As an operation method, after pressing the operation mode switching button 504 to select it, the operation mode of the settlement device 30 corresponding to the pressed settlement machine designation button 501 can be switched.

[0072] For example, when the operation mode switching button 504 is pressed to select the operation mode, and then the settlement machine designation button 501 of settlement machine 1 is pressed, the registration device 20 sends an operation mode switching instruction message to the settlement device 30 corresponding to settlement machine 1. The same applies when switching the operation mode of the settlement device 30 corresponding to settlement machine 2 or 3. In this way, when the registration device 20 receives an operation to switch the operation mode of each settlement device 30, it sends an operation mode switching instruction message to each settlement device 30 based on the received operation.

[0073] Furthermore, the settlement device 30 that receives the operation mode switching instruction message switches the operation mode. For example, if the settlement device 30 receives the operation mode switching instruction message while operating in the "full self" operation mode, it switches the operation mode to "semi-self" operation. For example, if the settlement device 30 receives the operation mode switching instruction message while operating in the "semi-self" operation mode, it switches the operation mode to "full self" operation. This allows the registration device 20 to accept an operation to switch the operation mode of each settlement device 30, and to switch the operation mode of each settlement device 30 based on the accepted operation.

[0074] In addition, similar to the method of switching the operation mode of the settlement device 30 from the registration device 20, the operation mode of the settlement device 30 may be switched from the store controller 10.

[0075] Furthermore, for example, the settlement device 30 may switch its operating mode depending on the number of people who have paid per unit time. For example, the settlement device 30 operates in semi-self-service mode when the number of people is equal to or greater than a predetermined threshold, and operates in full-self-service mode when the number of people is less than the predetermined threshold. The settlement device 30 may also switch its operating mode depending on the number of people who have paid in each time period on the same day of the previous day or last week. For example, the settlement device 30 operates in semi-self-service mode during time periods when the number of people is equal to or greater than a predetermined threshold, and operates in full-self-service mode during time periods when the number of people is less than the predetermined threshold.

[0076] Furthermore, the payment terminal 30 may switch its operating mode based on employee shift information. For example, the payment terminal 30 operates in semi-self-service mode during a time period when the number of employees on shift is equal to or greater than a predetermined threshold, and operates in full-self-service mode during a time period when the number of employees on shift is less than the predetermined threshold.

[0077] Furthermore, for example, the settlement device 30 may switch its operating mode depending on whether or not the scale 50 is connected. For example, the settlement device 30 operates in semi-self-service mode when the scale 50 is not connected, and operates in full-self-service mode when the scale 50 is connected.

[0078] Furthermore, for example, the settlement device 30 may switch its operating mode by turning on / off the scanner unit 304. For example, the settlement device 30 operates in full self-service mode when the scanner unit 304 is on, and operates in semi-self-service mode when the scanner unit 304 is off.

[0079] Furthermore, for example, the settlement device 30 may switch the operation mode to full self-service mode when a certain time has elapsed since logging out from semi-self-service mode. Similarly, the settlement device 30 may switch the operation mode to semi-self-service mode when a certain time has elapsed since logging out from full self-service mode.

[0080] In addition, the settlement device 30 may operate the scale 50 in a weighing mode in which the product is weighed in the full self-service mode, and may operate the scale 50 in a non-weighing mode (in which the product is not weighed) in the semi-self-service mode.

[0081] Furthermore, in the above-described embodiment, the mode in which the settlement device 30 that should execute the settlement process in semi-self-service mode is specified is described as a mode in which a store clerk specifies the settlement device 30 that should execute the settlement process using the registration device 20. However, this is not limiting, and the mode may also be such that, for example, the store clerk issues a medium for the settlement process (a receipt voucher (registered trademark)) to be handed to the customer using the registration device 20, and the customer has one settlement device 30 read the receipt handed to them by the store clerk. In other words, the customer specifies the settlement device 30 that should execute the settlement process from among multiple settlement devices 30 by having the settlement device 30 read the receipt handed to them by the store clerk.

[0082] The registration data identification information and registration device identification information are printed on the receipt in the form of either a one-dimensional code or a two-dimensional code. When the receipt is read by the settlement device 30, the registration data generated in the registration device 20 (the registration data corresponding to the receipt) is sent via LAN 11 to the settlement device 30 that read the receipt.

[0083] That is, when the payment device 30 reads a payment ticket, it requests (sends request information) the registration data corresponding to that payment ticket (the registration data identified by the registration data identification information obtained from the payment ticket) from the registration device 20 corresponding to that payment ticket (the registration device 20 identified by the registration device identification information obtained from the payment ticket), and the registration device 20 that received the requested registration data sends the requested registration data to the payment device 30 that made the request. The payment device 30 may request the registration data from the registration device 20 via the store controller 10. The registration device 20 may also send the registration data to the payment device 30 via the store controller 10. The registration device 20 may issue a payment ticket on which the registration data is printed as a two-dimensional code, instead of a payment ticket on which the registration data identification information and registration device identification information are printed as a one-dimensional or two-dimensional code. When the payment device 30 reads a payment ticket on which the registration data is printed as a two-dimensional code, it obtains the registration data directly from the payment ticket.

[0084] Furthermore, for example, even if the settlement device 30 is operating in full self-service mode, if a bill is read, the settlement device 30 may be configured to operate in semi-self-service mode.

[0085] Furthermore, for example, when the settlement device 30 performs a recall or hold after switching the operation mode and returns to the settlement process that was performed in the operation mode before the switch, the settlement device 30 may temporarily return to the operation mode before the switch. Furthermore, for example, when the settlement device 30 performs a recall or hold after switching the operation mode and returns to the settlement process that was performed in the operation mode before the switch, the settlement device 30 may temporarily display a pop-up screen asking whether or not to return to the operation mode before the switch.

[0086] Next, we will explain the settlement screen of the settlement device 30 when operating in semi-self mode. Figure 11 is a diagram showing an example of a screen that the settlement device displays when operating in semi-self mode, allowing the user to select a payment method. When the settlement device 30 reads out registered data, it displays a screen that allows the user to select a payment method, as shown in Figure 11. In the example shown, the screen for selecting the payment method displays the purchase amount, operation keys "cash", "credit", and "electronic money A" to "electronic money D", etc.

[0087] When "cash" is selected as the payment method on the screen for selecting the payment method shown in FIG. 11, the settlement device 30 displays a screen displaying the deposit amount, etc. FIG. 12 is a diagram showing a screen displaying the deposit amount, etc., displayed by the settlement device when operating in semi-self-service mode. In the example shown, an image is displayed in which the guidance "coin" indicating the position of the coin slot 312 and the guidance "banknote" indicating the position of the banknote slot 313 flash, and an image is displayed in which an imitation banknote is inserted into the banknote slot 313. The purchase amount and the deposit amount are displayed. This allows the customer to easily grasp the position of the banknote slot 313. The customer can also grasp the purchase amount and the deposit amount.

[0088] When the customer deposits cash while the screen shown in Figure 12 is displayed, the settlement device 30 performs the settlement process, and ends the process when the settlement process is complete. Note that even if a payment method other than "cash" is selected on the screen for selecting the payment method shown in Figure 11, the settlement device 30 performs the settlement process in the same way as when "cash" is selected as the payment method. Note that the screen displayed by the settlement device 30 when operating in semi-self mode is not limited to the examples shown in Figures 11 and 12, and may be any screen.

[0089] The settlement device 30 may also indicate the operation mode by changing the appearance of the sign pole 311 depending on the operation mode. For example, the settlement device 30 may light the sign pole 311 in blue when operating in semi-self-service mode, and light the sign pole 311 in green when operating in full-self-service mode. Also, for example, the settlement device 30 may light the sign pole 311 continuously in blue when operating in semi-self-service mode, and light the sign pole 311 in flashing blue when operating in full-self-service mode. Note that the appearance of the sign pole 311 according to the operation mode is not limited to the above, and any appearance may be used as long as it is possible to determine the operation mode of the settlement device 30.

[0090] Alternatively, the settlement device 30 may be configured as a face-to-face settlement device, with the display units 305 provided on both the front and rear sides and the settlement unit 310, which can accept cash payments, facing the customer. The scanner units 304 may be provided on both the front and rear sides, or a single scanner unit 304 may be used for both sides. For example, the scanner unit 304 may be configured to be rotatable, so that the scanner unit 304 can be moved to the front or rear side as desired by rotating it. Also, for example, the cable connecting the main body of the settlement device 30 and the scanner unit 304 may be lengthened so that it can be used on both the front and rear sides.

[0091] 13 is a diagram showing an example of the appearance of a payment device 30 in this embodiment, in which a display unit 305 and an operation unit 306 are provided on the front and rear sides, respectively. In the example shown, the payment device 30 is used with the front side facing the customer and the rear side facing the store clerk.

[0092] 13(A) shows an example of semi-self-service mode operation. After a store clerk registers the purchased items using the display unit 305, operation unit 306, and scanner unit 304 on the rear side, the customer operates the payment unit 310 to perform the payment process.

[0093] 13(B) shows an example of operation in full self-service mode. In the example shown, a customer registers the purchased items using the display unit 305, operation unit 306, and scanner unit 304 on the front side, and then operates the payment unit 310 to perform the payment process.

[0094] In this way, by providing a display unit 305 and an operation unit 306 on the front and back sides of the checkout device 30, respectively, the checkout device 30 can be operated in a semi-self-service mode in which the store clerk registers the purchased items and the customer processes the checkout, and a full-self-service mode in which the customer registers the purchased items and processes the checkout.

[0095] A switching key may be provided on operation unit 306, and pressing the switching key may allow switching between semi-self-service mode and full-self-service mode operation. When payment device 30 is operating in full-self-service mode, display unit 305 on the rear side (store clerk side) may display a message indicating that it is operating in full-self-service mode.

[0096] The method for switching the operating mode of the settlement device 30 between the semi-self-service mode and the full-self-service mode is not limited to pressing a switching key, and any method may be used. For example, the settlement device 30 may be configured so that the scanner unit 304 can be rotated, and when the scanner unit 304 is rotated to move it to the front side (customer side), the settlement device 30 operates in the full-self-service mode, and when the scanner unit 304 is rotated to move it to the rear side (clerk side), the settlement device 30 operates in the semi-self-service mode. Also, the settlement device 30 may be configured so that a payment terminal (electronic money, credit terminal) is provided and can be rotated, and when the payment terminal is rotated to move it to the front side (customer side), the settlement device 30 operates in the full-self-service mode, and when the payment terminal is rotated to move it to the rear side (clerk side), the settlement device 30 operates in the semi-self-service mode.

[0097] Also, for example, scanner units 304 may be provided on the front and back sides of the settlement device 30, and when the scanner unit 304 on the front side (customer side) is used, the settlement device 30 may operate in full self-service mode, and when the scanner unit 304 on the back side (clerk side) is used, the settlement device 30 may operate in semi-self-service mode.

[0098] Furthermore, for example, when registering purchased items at a convenience store, the purchase is often registered after first reading the clerk barcode with scanner unit 304. Therefore, scanning the clerk barcode with scanner unit 304 may switch from full self-service mode to semi-self-service mode. Furthermore, settlement device 30 may switch from semi-self-service mode to full self-service mode when the settlement process is completed (for example, immediately after the settlement process is completed, or after a predetermined time has elapsed since the settlement process was completed). In this way, automatic switching to full self-service mode allows for efficient settlement.

[0099] In addition, the settlement device 30 may be configured so that it cannot switch between semi-self-service mode and full-self-service mode when it is performing registration processing or settlement processing, and can switch between semi-self-service mode and full-self-service mode only when it is on standby.

[0100] The mode may also be changed automatically when the number of store clerks logged in to the payment terminals 30 falls below (or exceeds) a predetermined number. Specifically, when the number of store clerks is fewer than the number of payment terminals 30 (for example, when there are two payment terminals 30 and one store clerk, or when there are three payment terminals 30 and one or two store clerks), one or more payment terminals 30 will definitely not be staffed by a store clerk, so the unoccupied payment terminals 30 may be switched to full-self-service mode. When the number of payment terminals 30 is the same as the number of store clerks, or when there are more than two store clerks (for example, when there are two payment terminals 30 and two or more store clerks, or when there are three payment terminals 30 and three or more store clerks), the payment terminals 30 may be switched to semi-self-service mode because a store clerk can definitely be assigned to each payment terminal 30.

[0101] Alternatively, the semi-self-service mode and full-self-service mode may be switched by vocally inputting "mode switch." For example, a voice input device may be provided in the payment device 30, or voice input may be made using an external terminal (for example, a host server, a mobile terminal carried by a store clerk, etc.).

[0102] In addition, if a switching key is provided on the display unit 305 or operation unit 306 on the rear side (store clerk side), after switching from semi-self-service mode to full-self-service mode by operating the switching key, when switching back to semi-self-service mode, if the settlement process in full-self-service mode has not been completed, the switching key may be prohibited from being pressed.

[0103] In addition, if display units 305 are provided on both the rear side (clerk side) and the front side (customer side), when switching to full self-service mode, if the payment process is not completed after a predetermined time has passed after the registration of the purchased items has been completed, an error may be displayed on display unit 305 on the rear side (clerk side).

[0104] Furthermore, when the settlement device 30 is operating in semi-self-service mode, the customer may be allowed to register a different product when the clerk processes the utility bill payment. This is not limited to utility bill payments. The customer may also be allowed to register a different product when the clerk processes payments for pre-orders, ticket issuance, stamp sales, cigarettes, and other items that, unlike regular products, may require separate payments due to limited payment methods (cash only). This significantly reduces the time required to register purchased products. At this time, the products registered by the clerk and the products registered by the customer may be displayed separately. This makes it easier to detect incorrect or fraudulent registrations by the customer.

[0105] Even if there are no restrictions on payment methods, such as for utility bills, for items that can only be picked up by store clerks, such as prepared foods, steamed buns, donuts, and coffee, it may be possible for customers to register other items while the store clerk is registering these items. In this case, too, the registration of purchased items can be overlapped, significantly reducing the time required for registering purchased items.

[0106] Furthermore, the scanner unit 304 may be provided on both the store clerk side and the customer side, so that purchased items can be registered on both the store clerk side and the customer side. In this case, the registration of purchased items can be overlapped, and the time required for the registration process of purchased items can be significantly reduced.

[0107] Furthermore, when the payment terminal 30 is operating in full self-service mode, if a customer registers an item that must be picked up by a store clerk, such as cigarettes, steamed buns, donuts, or coffee, by operating the display unit 305, by scanning a barcode on a medium with the scanner unit 304, or by using a wireless tag, information indicating which payment terminal 30 it is (e.g., the number of the payment terminal 30) may also be notified to a payment terminal 30 in semi-self-service mode where a store clerk is present. When notifying the customer of the item that needs to be picked up by the store clerk and the information indicating which payment terminal 30 it is, the registered product name may also be notified. The notification method may be, for example, a pop-up display, a sound, a vibration, or receipt printing. Then, based on the notification, the store clerk may take the notified item and go to the payment terminal 30 operating in full self-service mode after finishing handling the customer in semi-self-service mode. This allows the customer to pick up the item before going to the payment terminal 30 operating in full self-service mode, eliminating the need for double effort.

[0108] Furthermore, when the checkout device 30 is operating in full-self-service mode, if a customer registers an item that must be picked up by a store clerk, such as cigarettes or steamed buns, by operating the display unit 305, by scanning a barcode on a medium with the scanner unit 304, or by using a wireless tag, the checkout device 30 may be configured to notify the store clerk in semi-self-service mode. At this time, the storage location, such as a shelf, where the item is placed may be notified. The notification method may be, for example, by lighting or flashing a lamp or the like indicating the storage location, or by outputting a voice message saying, "XX has been selected." This allows the store clerk to select an item more easily. Even when operating in semi-self-service mode, the storage location, such as a shelf, where the item is placed may be notified.

[0109] Furthermore, settlement units 310 may be provided on the front and back of the settlement device 30, and the settlement device 30 may operate in a normal mode in which a store clerk registers purchased items and processes the settlement, in addition to the semi-self-service mode and full-self-service mode. The settlement device 30 may be configured to be able to perform the above-mentioned processes when operating in the normal mode, just as when operating in the semi-self-service mode.

[0110] Furthermore, in a POS system equipped with a face-to-face settlement device 30 operating in semi-self-service mode, when tallying up the day's cash registers (closing), it is expected that customers will want to perform as many operations as possible on the customer side to avoid inconvenience to the customer, or that customers will want to avoid seeing the screen operated by the store clerk, such as information on the number of coins in each denomination. On the other hand, there are some items that must be displayed when operating the settlement unit 310 (change dispenser) (e.g., the number of coins in each denomination, a confirmation button, and a final button to start closing). Therefore, by displaying a certain part of a series of processes on the rear (clerk-side) display unit 305 and then displaying the rest on the front (customer-side) display unit, it is possible to perform as many necessary processes as possible on the rear (clerk-side) side and the minimum necessary processes on the front (customer-side) side. When a screen is displayed on the front (customer-side) display unit 305, the same screen may be mirrored and displayed on the rear (clerk-side) display unit 305.

[0111] As a similar example, error processing guidance that customers do not want to see in response to an error notification such as error processing of the settlement unit 310 (change dispenser) or running out of receipt paper (for example, information such as "please contact XX", jammed banknotes or coins, or a shortage of a specific denomination) may be displayed on the rear (clerk-side) display unit 305, and until the necessary processing is carried out on the rear (clerk-side) side, a message such as "Error processing is being carried out" may be displayed on the front (customer-side) display unit 305. Furthermore, when replenishing missing banknotes or coin rolls or removing excess banknotes, error processing guidance may be displayed on the rear (clerk-side) display unit 305, and until the necessary processing is carried out on the rear (clerk-side) side, a message such as "Error processing is being carried out" may be displayed on the front (customer-side) display unit 305.

[0112] Furthermore, especially at convenience stores late at night, there are often few store clerks on hand, and they are often busy with tasks other than cashier duties, such as stocking and displaying merchandise, so they may not notice a customer's desire to pay. Therefore, when a customer operates checkout device 30 to begin registering purchased items in full-self-service mode, a notification may be issued that the purchased items are being registered in full-self-service mode (for example, a lamp may come on, a predetermined sound may be emitted, or a mobile device held by the clerk may display which register the customer is using for full-self-service checkout). The clerk who notices the notification may then go to the register, switch from full-self-service mode to semi-self-service mode even if the customer is in the middle of registering the purchased items, and continue registering any unregistered purchased items, allowing the customer to insert cash first. This will improve the efficiency of the checkout process and increase customer satisfaction.

[0113] In addition, a program for implementing the functions of the registration device 20 and settlement device 30 may be recorded on a computer-readable recording medium, and the program may be loaded into a computer system and executed to perform the processing of the registration device 20 and settlement device 30. Here, "loading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The term "computer system" here includes hardware such as an operating system and peripheral devices. The term "computer system" may also include multiple computers connected via a network, including communication lines such as the Internet, a WAN, a LAN, and a dedicated line. The term "computer-readable recording medium" refers to portable media such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, as well as storage devices such as a hard disk built into a computer system. In this way, the recording medium storing the program may also be a non-transitory recording medium such as a CD-ROM.

[0114] The term "recording medium" also includes internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code in a format executable on a terminal device. In other words, the format in which the program is stored on the distribution server is not important as long as it can be downloaded from the distribution server and installed in a format executable on a terminal device. The program may be divided into multiple parts, downloaded at different times, and then combined on a terminal device, or each part may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that serves as a server or client when a program is transmitted over a network. The program may also be a storage medium for implementing part of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that can realize the above-described functions in combination with a program already stored in the computer system.
