Description

[Technical field]

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

[0002] There is known a POS system in which a registration device for registering products and a settlement device for settling the products registered by the registration device are separate devices (see, for example, Patent Document 1). In such a POS system, a store clerk uses the registration device to register products purchased by customers, and the customers can settle the payments for their purchased products at the settlement device. This, for example, can save labor by automating the process of receiving product prices, and can shorten the time from registering purchased products to completing settlement. [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, in the technology described in Patent Document 1, when there is no store clerk to operate the registration device, the corresponding settlement device is not used. Therefore, there are times when the settlement device cannot be used, and the settlement device is not always 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 equipped with 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 comprising 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 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 the settlement device 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 is equipped with a key that accepts an operation 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 the 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, even if the mode change means is operating in the full-self-service mode, it may be arranged to operate in the semi-self-service mode when it reads information to be used in the semi-self-service mode.

[0010] Moreover, one aspect of the present invention is a settlement device included in a POS system equipped with a registration device in which a store clerk registers items purchased by a customer and a settlement device, the settlement device having two operating modes: a semi-self-service mode in which the customer pays for items registered in the registration device, and a full-self-service mode in which the customer registers the items they have purchased and pays for them, 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 mode change means switching 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 a customer and a settlement device to operate in two operating modes, a semi-self-service mode in which a customer settles for items registered in the registration device, and a full-self-service mode in which a customer registers and settles for the items they have purchased, and a step of switching the operating mode to either the semi-self-service mode or 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. Effect of the Invention

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 settlement devices 30. The store controller 10, the registration device 20, and the three settlement devices 30 are connected to 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 may include two or less or four or more settlement devices 30. The POS system may not include a store controller 10. If the POS system does not include a store controller 10, another device (for example, a registration device 20, or a representative registration device 20 in the case of two or more registration devices 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 transmits the latest product master to the registration device 20 and each settlement device 30 as appropriate. 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, discount information, etc. 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, etc.) and transmits it to the registration device 20 and each settlement device 30 as appropriate.

[0017] The registration device 20 executes a registration process for registering 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, registration date and time, product identification information for each registered product, product name, sales price, discount information, transaction points (purchase points) indicating the number of products to be purchased, and total price (total amount) 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 settlement processing in the settlement device 30. The settlement processing 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 mode for designating the settlement device 30 that should execute the settlement process from among the multiple settlement devices 30 is for a store clerk to designate the settlement device 30 that should execute the settlement process using the registration device 20. That is, the store clerk performs an operation to designate the settlement device 30 on the registration device 20, thereby designating the settlement device 30 that should execute the settlement process from among the multiple settlement devices 30. The registration device 20 may be configured to display operation information showing the operation status of each settlement device 30, so that the operation status of each settlement device 30 can be confirmed on the registration device 20 when the store clerk designates 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 settlement device 30 has two operation modes: a semi-self-service mode in which a store clerk registers the products purchased by a customer on a registration device and the customer pays for the registered products on the settlement device, and a full-self-service mode in which the customer registers the purchased products on the settlement device and pays for them. In the semi-self-service mode, the settlement device 30 executes a settlement process for the products registered on the registration device in response to the customer's operation. That is, the settlement device 30 executes a settlement process based on the registration data received from the registration device 20. Furthermore, when the settlement device 30 ends the settlement process in the semi-self-service mode, it notifies the registration device 20 of the end of the settlement process. On the other hand, in the full-self-service mode, the settlement device 30 executes a registration process for registering the products to be purchased in response to the customer's operation, and then executes a settlement process for the registered products.

[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 The device includes a memory unit (RAM) 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, and controls the operation of the registration device 20 by reading and executing programs stored in the ROM 202 . The ROM 202 is a read-only memory, and stores various types of information used by the CPU 201, including programs.

[0026] The RAM 203 is a 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 related to 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) and 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] The display unit (for customers) 205a displays various information for customers. For example, the display unit (for customers) 205a displays the prices of registered products. The display unit (for customers) 205a may be a touch panel (for example, a liquid crystal touch panel).

[0029] The operation unit 206 includes various operation buttons (such as a subtotal key, a running total key, a number entry key, a correction key, and a preset key) 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 (such as a product code) that is set and registered in advance in the 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 that guides the payment device 30 designated by the store clerk.

[0031] In FIG. 4, the external configuration of a scanner unit 204, a display unit (for store clerk) 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, and 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, and stores various types of information used by the CPU 301, including programs.

[0034] The RAM 303 is a random access memory that 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 is 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 by operating an operation button (correction key).

[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., the payment of the purchase amount of the product) is completed, the printing unit 309 prints and issues a receipt that indicates the payment result and is 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 execution of the settlement (for example, information indicating whether the settlement has been established or not) to the CPU 301 via the bus. The change dispenser includes 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 a money slot. Furthermore, the settlement unit 310 executes settlement using credit and outputs the result of the settlement via the port and the bus to the CPU 301. Furthermore, the settlement unit 310 executes 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 blinking 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 an item, and is used to prevent fraud when a customer registers an item to be purchased in the full self-service mode.

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

[0042] 6 and 7 are examples of screens displayed on the settlement device 30. In the semi-self-service mode, the settlement device 30 executes settlement processing for products registered in the registration device 20. That is, when the settlement device 30 is in the semi-self-service mode, a store clerk registers products in the registration device 20, and a customer operates the settlement device 30 to settle the payment for the products registered in the registration device 20. In addition, in the full-self-service mode, the settlement device 30 executes registration processing for products and settlement processing for the registered products. That is, when the settlement device 30 is in the full-self-service mode, a 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 the semi-self-service mode. The CPU 301 (mode change means) of the settlement device 30 can switch the operation mode between the semi-self-service mode and the full-self-service mode. For example, the CPU 301 switches the operation mode from the semi-self-service mode to the full-self-service mode when a predetermined condition is satisfied. The predetermined condition is, for example, that the scanner unit 304 has read code information attached to the product. In this case, the CPU 301 switches the operation mode to the full-self-service mode when the scanner unit 304 has read code information attached to the product. Then, the CPU 301 switches the operation mode to the semi-self-service mode when the settlement process is completed. Alternatively, the CPU 301 may switch the operation mode to the semi-self-service mode when registration data is received from the registration device 20. Alternatively, the CPU 301 may switch the operation mode to the semi-self-service mode when a predetermined operation is performed.

[0044] Another example of the predetermined condition is that a predetermined time period has arrived. In this case, the CPU 301 switches the operation mode to the full self-service mode when the predetermined time period (time) has arrived, and switches the operation mode to the semi-self-service mode when the time period has passed. Another example of the predetermined condition is that the registration device 20 set corresponding to the settlement device 30 is not in operation. In this case, the CPU 301 switches the operation mode to the full self-service mode when the corresponding registration device 20 is not in operation, and switches the operation mode to the semi-self-service mode when the corresponding registration device is in operation. The corresponding registration device 20 is set in advance 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 not in operation when the CPU 301 has not received registration data for a predetermined time or more, and may determine that the corresponding registration device 20 is in operation when the CPU 301 has received registration data.

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

[0046] Furthermore, in full self-service mode, the settlement 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 "Select a button to start registration" 701 that prompts the customer to register products, 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. When the registration of the products is completed, the settlement device 30 displays the settlement screen 600 on the display unit 305 and executes the settlement 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 in semi-self-service mode, and lights up the sign pole 311 in red in full-self-service mode. This allows the operation mode of the settlement device 30 to be confirmed 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 allows the operation mode of the settlement device 30 to be known even from a distance.

[0049] Next, an example of process transition of the settlement device 30 of this embodiment will be described with reference to the flowcharts of Fig. 8 and Fig. 9. In the initial state, the settlement device 30 is in a standby state. The standby state is a state in which 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 Fig. 8.

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

[0051] (Step S102) The CPU 301 reads out the registration data received in advance 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 out 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 finishes 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 a 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-service mode. (Step S201) CPU 301 determines whether the above-mentioned predetermined condition is satisfied. If CPU 301 determines that the predetermined condition is satisfied, the process proceeds to step S202. If CPU 301 determines that the predetermined condition is not satisfied, the process of step S201 is executed 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, transmits 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. When the registration device 20 receives the alert, it displays 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 the registered data received from the registration device 20 has been settled. If the CPU 301 determines that all 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 a standby state in the full self-service mode, if the above-mentioned predetermined conditions are no longer satisfied, the settlement device 30 may switch the operation mode from the full self-service mode to the 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 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 pays for 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.

[0060] According to the above configuration, the settlement device can be used as a fully self-service settlement machine where the customer registers and settles for products. Therefore, even when there is no store clerk to operate the registration device, the settlement device can be used, and the settlement device can be effectively utilized.

[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 changing means switches the operation mode to the 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 the 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 the full self-service mode.

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

[0063] Furthermore, in the POS system of this embodiment, the mode change means switches the operation mode to the 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 the 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 designs that do not deviate from the gist of the present invention are also included.

[0065] For example, in the above embodiment, the settlement device 30 switches the operation mode to the semi-self mode when a certain condition is satisfied, but the method of switching the operation mode is not limited to this. For example, the settlement device 30 may switch the operation mode when the scanner unit 304 reads a barcode (clerk code) attached to a clerk card owned by a clerk. Alternatively, the settlement device 30 may switch the operation 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] 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 as shown in FIG. The registration screen shown in Figure 10 has preset buttons (buttons labeled "Strawberry", "Apple", etc.) associated with product information (product code, etc.), as well as a settlement machine designation button 501 (buttons labeled "Settlement Machine 1", "Settlement Machine 2", "Settlement Machine 3") for designating the settlement device 30 that will execute the settlement process (i.e. the settlement device 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 switch button 504 for switching the operation mode of the settlement device 30.

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

[0069] In the illustrated example, each settlement machine designation button 501 displays the status (condition, operation 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, as illustrated, 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 the 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 according to the status.

[0071] In addition, 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 transmits 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 transmits 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 an operation mode switching instruction message while operating in the "full self" operation mode, it switches the operation mode to "semi-self". For example, if the settlement device 30 receives an operation mode switching instruction message while operating in the "semi-self" operation mode, it switches the operation mode to "full self". 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, it may be possible to switch the operation mode of the settlement device 30 from the store controller 10.

[0075] Also, for example, the settlement device 30 may switch the operation 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. Also, the settlement device 30 may switch the operation 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 a time period when the number of people is equal to or greater than a predetermined threshold, and operates in full-self-service mode during a time period when the number of people is less than the predetermined threshold.

[0076] Also, for example, the settlement device 30 may switch the operation mode based on the shift information of the store clerk. For example, the settlement device 30 operates in the semi-self-service mode during a time period when the number of store clerks on shift is equal to or greater than a predetermined threshold, and operates in the full-self-service mode during a time period when the number of store clerks on shift is less than the predetermined threshold.

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

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

[0079] Also, for example, the settlement device 30 may switch the operation mode to the full self-service mode when a certain time has elapsed since logging out from the semi-self-service mode. Similarly, the settlement device 30 may switch the operation mode to the semi-self-service mode when a certain time has elapsed since logging out from the 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 set the scale 50 to a non-weighing mode (in which the product is not weighed) in the semi-self-service mode.

[0081] In the above embodiment, the mode of designating the settlement device 30 that should execute the settlement process in the semi-self-service mode has been described as a mode in which the store clerk designates the settlement device 30 that should execute the settlement process using the registration device 20. However, the present invention is not limited to this mode, and may be modified in another way, for example, in which the store clerk issues a medium for the settlement process (a receipt (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 designates 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] On the receipt, the registration data identification information and the registration device identification information are printed 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 transmitted via the LAN 11 to the settlement device 30 that read the receipt.

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

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

[0085] Also, for example, the settlement device 30 may perform a recall or hold after switching the operation mode, and when returning to settlement processing that was processed in the operation mode before the switch, it may temporarily revert to the operation mode before the switch. Also, for example, the settlement device 30 may perform a recall or hold after switching the operation mode, and when returning to settlement processing that was processed in the operation mode before the switch, it may display a pop-up screen asking whether or not to temporarily revert to the operation mode before the switch.

[0086] Next, the settlement screen of the settlement device 30 when operating in semi-self mode will be described. Fig. 11 is a diagram showing an example of a screen displayed by the settlement device when operating in semi-self mode, for selecting a payment method. When the settlement device 30 reads out registered data, it displays a screen for selecting a payment method, as shown in Fig. 11. In the example shown, the screen for selecting the payment method displays the purchase amount, the operation keys "cash" and "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 mode. In the illustrated example, an image in which the guidance "coin" indicating the position of the coin insertion slot 312 and the guidance "banknote" indicating the position of the banknote insertion slot 313 flash, and an image in which a dummy banknote is inserted into the banknote insertion slot 313 are displayed. The purchase amount and the deposit amount are displayed. This allows the customer to easily grasp the position of the banknote insertion 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 Fig. 12 is displayed, the settlement device 30 performs settlement processing, and ends the processing when the settlement processing is completed. Note that even if a payment method other than "cash" is selected on the screen for selecting a payment method shown in Fig. 11, the settlement device 30 performs settlement processing 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 Figs. 11 and 12, and may be any screen.

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

[0090] Also, the settlement device 30 may be a face-to-face settlement device in which the display units 305 are provided on the front and rear sides, and the settlement unit 310 capable of cash settlement is directed toward the customer. The scanner unit 304 may be provided on the front and rear sides, or one scanner unit 304 may be used in common. For example, the scanner unit 304 may be configured to be rotatable, and the scanner unit 304 may be moved to the front side or the rear side 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 side and the rear side.

[0091] 13 is a diagram showing an example of the appearance of a settlement 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 in the figure, the settlement device 30 is used with the front side facing the customer and the rear side facing the store clerk.

[0092] 13A shows an example of the semi-self mode. After the 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 carry out the payment process.

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

[0094] In this way, by providing a display unit 305 and an operation unit 306 on the front and back sides, respectively, the settlement 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 settlement, and a full-self-service mode in which the customer registers the purchased items and processes the settlement.

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

[0096] The method of switching between the semi-self-service mode and the full-self-service mode as the operation mode of the settlement device 30 is not limited to pressing a switching key, and any method may be used. For example, the settlement device 30 may be configured to be rotatable, and when the scanner unit 304 is moved to the front side (customer side) by rotation, the settlement device 30 operates in the full-self-service mode, and when the scanner unit 304 is moved to the rear side (clerk side) by rotation, the settlement device 30 operates in the semi-self-service mode. Also, the settlement device 30 may be configured to be provided with a payment terminal (electronic money, credit terminal) and be rotatable, and when the payment terminal is moved to the front side (customer side) by rotation, the settlement device 30 operates in the full-self-service mode, and when the payment terminal is moved to the rear side (clerk side) by rotation, 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 rear 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 rear 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 store clerk barcode is often read by the scanner unit 304 first, and then the purchased items are registered. Therefore, the store clerk barcode may be read by the scanner unit 304 to switch from the full self-service mode to the semi-self-service mode. The settlement device 30 may also switch from the semi-self-service mode to the full self-service mode when the settlement process is completed (for example, immediately after the settlement process is completed, or a predetermined time has elapsed since the settlement process is completed). In this way, automatic switching to the full self-service mode allows for efficient settlement.

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

[0100] Also, the mode may be changed automatically when the number of store clerks logged in to the settlement devices 30 falls below (or exceeds) a predetermined number. Specifically, when the number of store clerks is less than the number of settlement devices 30 (for example, when there are two settlement devices 30 and one store clerk, or when there are three settlement devices 30 and one or two store clerks), one or more settlement devices 30 will definitely not be staffed by a store clerk, so the settlement devices 30 that become vacant may be switched to full self-service mode. Also, when the number of settlement devices 30 and the number of store clerks are the same or greater (for example, when there are two settlement devices 30 and two or more store clerks, or when there are three settlement devices 30 and three or more store clerks), the settlement devices 30 may be switched to semi-self-service mode, so that a store clerk can definitely be assigned to the settlement devices 30.

[0101] Also, as a method of switching between the semi-self-service mode and the full-self-service mode, the mode may be switched by inputting "mode switch" by voice. For example, a voice input device may be provided in the settlement device 30, or voice input may be made at an external terminal (for example, a higher-level server, a mobile terminal held 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), when switching from semi-self-service mode to full-self-service mode by operating the switching key and then switching back to semi-self-service mode, if the settlement process in full-self-service mode has not been completed, the operation of the switching key may be prohibited.

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

[0104] In addition, when the settlement device 30 is operating in the semi-self mode, the customer may be allowed to register a different product when the clerk processes the payment of utility bills. In addition to the payment of utility bills, the customer may be allowed to register a different product when the clerk processes the payment of items such as advance sales, ticket issuance, postage stamp sales, and cigarettes, which are different from normal products and may require separate accounting because the payment method is limited (only cash is allowed). This can significantly reduce 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 can make it easier for the customer to notice if they have registered incorrectly or fraudulently.

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

[0106] Also, a 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] In addition, when the settlement device 30 is operating in the full self-service mode, for products that can only be taken out by a store clerk, such as cigarettes, steamed buns, donuts, and coffee, if the customer operates the display unit 305 to register the product, or registers the product by reading a barcode on a medium with the scanner unit 304, or registers the product with a wireless tag, information indicating which settlement device 30 it is (for example, the number of the settlement device 30, etc.) may also be notified to the settlement device 30 in the semi-self-service mode where the store clerk is present. When notifying the information indicating whether the product needs to be taken out by the store clerk and the information indicating which settlement device 30 it is, the registered product name may also be notified. The notification method may be, for example, a pop-up display, a voice, a vibration, receipt printing, etc. Then, the store clerk may take the notified product and head to the settlement device 30 operating in the full self-service mode after finishing dealing with the customer in the semi-self-service mode based on the notification. This allows the customer to take the product before heading to the settlement device 30 operating in the full self-service mode, eliminating the need to do the double work.

[0108] In addition, when the settlement device 30 is operating in the full self-service mode, if a customer operates the display unit 305 to register an item such as cigarettes or steamed buns that can only be picked up by a store clerk, or registers the item by reading a barcode on a medium with the scanner unit 304, or registers the item by a wireless tag, the settlement device 30 in the semi-self-service mode where a store clerk is present may be notified of the fact. At this time, the storage location such as a shelf where the item is placed may be notified. The method of notification may be, for example, by turning on or blinking a lamp or the like of 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. Note that even when operating in the 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 even when operating in the normal mode, in the same way as when operating in the semi-self-service mode.

[0110] In addition, in a POS system equipped with a face-to-face settlement device 30 operating in a semi-self-service mode, when tallying up the cash register for the day (closing process), it is assumed that the customer wants to perform as many operations as possible on the customer's side to avoid causing inconvenience to the customer, or that the customer wants to avoid seeing the screen operated by the store clerk, such as the information on the number of denominations. On the other hand, there are some items that must be displayed when operating the settlement unit 310 (change dispenser) side (for example, the display of the number of denominations and a confirmation button for that, and a final closing process start button, etc.). In this case, by performing a process in which a certain part of a series of processes is displayed on the display unit 305 on the back side (clerk side) and the rest is displayed on the front side (customer side), it becomes possible to perform the necessary processes on the back side (clerk side) and the minimum necessary processes on the front side (customer side). Note that when a screen is displayed on the display unit 305 on the front side (customer side), the same screen may be mirrored and displayed on the display unit 305 on the back side (clerk side).

[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 out of receipt paper (for example, information display such as "please contact XX", jammed bills or coins, shortage of a specific denomination, etc.) may be displayed on the display unit 305 on the rear side (clerk side), and the display unit 305 on the front side (customer side) may simply display "error processing in progress" until the necessary processing is performed on the rear side (clerk side). Furthermore, when replenishing missing bills / coin bars or removing excess bills, error processing guidance may be displayed on the display unit 305 on the rear side (clerk side), and the display unit 305 on the front side (customer side) may simply display "error processing in progress" until the necessary processing is performed on the rear side (clerk side).

[0112] Furthermore, especially at convenience stores late at night, there are often few store clerks on duty, and they are often engaged in other tasks besides cashier duties, such as stocking and displaying merchandise, and may not notice that a customer wants to settle their bill. Therefore, when a customer operates the settlement device 30 to start 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 light may come on, a specified sound may be emitted, or a display may be displayed on the store clerk's mobile device indicating which register the customer is currently using for full self-service settlement). The store 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, and continue registering unregistered purchased items, and ask the customer to insert cash or perform other actions first. This will improve the efficiency of payment procedures and increase customer satisfaction.

[0113] In addition, a program for realizing the functions of the above-mentioned registration device 20 and settlement device 30 may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform the processing of the above-mentioned registration device 20 and settlement device 30. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including communication lines such as the Internet, WAN, LAN, and dedicated lines. In addition, the "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. In this way, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.

[0114] The recording medium also includes a recording medium provided inside or outside the distribution server that can be accessed in order to distribute the program. The code of the program stored in the distribution server's recording medium may be different from the code of the program in a format executable by the terminal device. In other words, the format in which the program is stored in the distribution server does not matter as long as it can be downloaded from the distribution server and installed in a format executable by the terminal device. The program may be divided into multiple parts, downloaded at different times, and then combined in the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a storage medium that holds a program for a certain period of time, such as a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network. The program may also be a storage medium for implementing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
