Description

[Technical Field]

[0001] FIELD OF THE INVENTION An embodiment of the present invention relates to a payment device. [Background technology]

[0002] BACKGROUND ART In recent years, self-checkout devices (self-registers) that can be operated by customers themselves when purchasing products have come into use in stores such as supermarkets and convenience stores.

[0003] Such self-checkout terminals are equipped with a payment device in which a customer, who is an operator, performs registration operations and payment operations (i.e., the operator is the customer himself). When a customer performs product registration operations at the payment device, a symbol such as a barcode attached to the product is imaged and read by an imaging unit (reading unit) composed of a camera provided in a reading unit provided in the payment device. Alternatively, the symbol is optically read by the reading unit. The customer then bags the read product into a bag. When the product whose symbol was read by the reading unit has been bagged, the light-emitting unit of the payment device emits a light to notify the customer. In addition, when the product whose symbol was read by the reading unit has not been bagged, the light-emitting unit also emits a light to notify the customer.

[0004] However, since the light-emitting unit is often located near a display unit that displays product information or near a reading unit, customers must look at the bag while packing the products, and then turn their eyes in the direction of the light-emitting unit to check whether the light-emitting unit is emitting light, making it difficult to check. Summary of the Invention [Problem to be solved by the invention]

[0005] The problem to be solved by the present invention is to provide a settlement device in which the operator can easily check the light emitted from the light-emitting unit. [Means for solving the problem]

[0006] The settlement device of the embodiment includes a reading unit that reads a symbol attached to a product, a bagging unit that is located near the reading unit and has an upper surface for bagging the product whose symbol is read by the reading unit, a weighing unit that weighs the bagged product, a light-emitting unit provided in the bagging unit, a determination means that determines whether the product read by the reading unit has been bagged using weight data measured by the weighing unit, and a light-emission control means that causes the light-emitting unit to emit light in either a first mode when it is determined that the product read by the reading unit has been bagged or a second mode when it is determined that the product read by the reading unit has not been bagged. ,of Preparation The light emission control means causes the light emitting unit to emit light in a third mode different from the first mode and the second mode when a first predetermined time has elapsed since the reading unit read the symbol but the weighing unit has not yet weighed it, and causes the light emitting unit to emit light in the second mode when a second predetermined time longer than the first predetermined time has elapsed since the reading unit read the symbol but the weighing unit has not yet weighed it. .

[Figure 6] FIG. 6 is a front view showing the appearance of a checkout device according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment will be described with reference to the drawings. In the embodiment, a payment device provided in a self-checkout device where a customer (operator) performs product registration and payment operations by himself / herself will be described as an example. Note that the present invention is not limited to the embodiment described below.

[0009] FIG. 1 is a perspective view showing the appearance of a self-checkout terminal 100 according to an embodiment. As shown in FIG. 1, the self-checkout terminal 100 includes a payment device 1 and a basket stand 2. The basket stand 2 has an upper surface 2a, and is a stand on which a customer places products to be purchased or a basket containing the products. The payment device 1 is a device that allows a customer to register and pay for the products placed on the upper surface 2a of the basket stand 2.

[0010] The payment device 1 comprises a registration device 11 and an accounting device 12. The registration device 11 is a device that performs product registration operations by reading symbols attached to products and weighing the read products. The accounting device 12 is a device that performs payment operations for products for which a registration operation has been performed. The registration device 11 is placed next to the basket stand 2, and the accounting device 12 is placed next to the registration device 11 on the opposite side of the basket stand 2.

[0011] The registration device 11 includes a display unit 41, an operation unit 42, a reading unit 43, and a light-emitting unit 44. The reading unit 43 has a reading window 43a and reads symbols such as barcodes or two-dimensional codes attached to products. The reading unit 43 reads the symbols by capturing an image of the symbols. Alternatively, the reading unit 43 scans a laser beam or the like onto the symbol and optically reads the symbol by incident reflected light. The display unit 41 is, for example, a liquid crystal display, and displays information to the customer who is the operator. The display unit 41 displays, for example, product information (product name, product price, etc.) of the product attached with the symbol read by the reading unit 43. The operation unit 42 is, for example, a transparent touch panel provided on the display surface of the display unit 41. The operation unit 42 functions as various keys operated by the customer.

[0012] The light emitting unit 44 is a light source that emits light and is configured, for example, with one or more LEDs (Light Emitted Diodes). The light emitting unit 44 emits light of multiple colors. For example, the light emitting unit 44 emits blue light. The light emitting unit 44 also emits red light. Emission includes lighting and blinking.

[0013] The registration device 11 also includes a bagging tool 13, a bagging unit 18, and a temporary storage table 19. The bagging tool 13 is a device for hooking a container for storing products, such as a bag or bag on which products are placed. The bagging tool 13 hooks onto the handle of the bag or bag. In the following description and claims, containers such as bags and bags will be collectively referred to as bags. The bagging unit 18 is a table with an upper surface for bagging products into bags hooked onto the bagging tool 13. The bottom of the bag hooked onto the bagging tool 13 comes into contact with the bagging unit 18. Therefore, products placed into the bag are placed on the bagging unit 18 via the bag. In other words, the weight of the products placed into the bag is borne by the bagging unit 18.

[0014] Temporary storage table 19 is a temporary storage table for products. For example, fragile products such as eggs and tofu are stored at the top of the bag, so temporary storage table 19 is a table on which the products are temporarily placed without being immediately put into a bag after the symbol is read by reader 43. Note that bagging tool 13 and temporary storage table 19 are attached to bagging unit 18.

[0015] The registration device 11 also includes a weighing unit 45. The weighing unit 45 is a scale for measuring the weight of the products. The weighing unit 45 is provided below the bagging unit 18, and measures the weight of the products placed on the bagging unit 18 (i.e., the products stored in bags hooked on the bagging tool 13). The weighing unit 45 also measures the weight of the products placed on the temporary storage table 19.

[0016] The light-emitting unit 44 is provided in the bagging unit 18 of the registration device 11, at a corner 48 on the front side where the customer stands, with the display surface facing upward (or diagonally upward toward the customer). The corner 48 is located so that it does not become a blind spot when the bag is hooked on the bagging tool 13 and placed on the bagging unit 18. The customer performs a series of operations to place the product, whose symbol has been read by the reading unit 43, into the bag while looking at at least the vicinity of the opening of the bag hooked on the bagging tool 13 (i.e., while checking the position of the opening), and the corner 48 is located within the field of view of the customer performing the operations. Therefore, the customer can check the form of light from the light-emitting unit 44 within the same field of view as when performing a series of operations to place the product, whose symbol has been read by the reading unit 43, into the bag. That is, the customer can check the form of light emitted by light-emitting unit 44 without having to change his or her line of sight from the field of view in which he or she performs the series of operations of putting the product, whose symbol has been read by reader 43, into the bag. Therefore, the customer who is the operator can easily check the light emitted by light-emitting unit 44.

[0017] In the registration device 11, the display unit 41, the operation unit 42, and the reading unit 43 are attached to a support 49 erected upward at the rear of the registration device 11 (opposite the corner 48 where the light-emitting unit 44 is provided). The display unit 41, the operation unit 42, and the reading unit 43 are not attached to the bagging unit 18 or the weighing unit 45.

[0018] The reading unit 43 is provided above the bagging unit 18. The opening of the bag hooked on the bagging tool 13 is located near the reading unit 43 and substantially below the reading unit 43.

[0019] The accounting device 12 is a device that performs payment operations for products that have been registered by the registration device 11. The accounting device 12 has a change machine (not shown) inside. The change machine stores banknotes and coins inside. The accounting device 12 has a coin slot 14 and a banknote slot 15. The coin slot 14 is an insertion section into which the coin portion of the deposit taken as the price for purchasing products is inserted. Coins inserted through the coin slot 14 are stored in the change machine. The banknote slot 15 is an insertion section into which the banknote portion of the deposit taken as the price for purchasing products is inserted. Banknotes inserted through the banknote slot 15 are stored in the change machine. The accounting device 12 also has a coin change slot 16 and a banknote change slot 17. When there is change to be handed to the customer for the deposited amount, the coin change slot 16 dispenses the change equivalent to the coins ejected from the change machine. When there is change to be handed to the customer for the amount of the deposit, the bill change slot 17 dispenses the change for the amount of the bills ejected from the change dispenser.

[0020] The settlement device 1 displays on the display unit 41 product information (product name, product price, etc.) of the product to which the symbol imaged by the registration operation is attached, and executes a product registration process to store the product information.

[0021] The checkout device 12 also includes a printer 46 and a card reader 47, which will be described later in Figure 2. When a payment operation is performed, the printer 46 executes payment processing by displaying the total amount for the registered products on the display unit 41, dispensing change from the change dispenser if any, and issuing a receipt with product information and payment information printed on it from the printer 46. The payment device 1 also includes a control unit 300, which will be described later in Figure 2.

[0022] In this payment device 1, a customer places the products they wish to purchase from those displayed in the store in a basket and places it on the upper surface 2a of the basket stand 2. Next, the customer removes the products from the basket and moves it to the position of the reading window 43a of the reading unit 43, causing the reading unit 43 to read the symbol attached to the product. Next, the customer continues this series of actions and places the products into a bag through the opening of the bag located near the reading unit 43 (i.e., packs the products into the bag).

[0023] The payment device 1 uses the reading unit 43 to read the symbols attached to the products. The payment device 1 also uses the weighing unit 45 to weigh the weight of the products placed in the bag. The payment device 1 then lights up the light-emitting unit 44 in blue (lights up in the first mode) when the product whose symbol has been read is stored in the bag. The payment device 1 also weighs the weight of the products stored in the bag, and lights up the light-emitting unit 44 in red (lights up in the second mode) when the product whose symbol has been read is not stored in the bag. The control of light emission by the light-emitting unit 44 will be described later with reference to FIG. 5.

[0024] Next, the hardware configuration of the payment device 1 according to the embodiment will be described. FIG. 2 is a block diagram showing the hardware configuration of the payment device 1. As shown in FIG. 2, the payment device 1 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, a memory unit 34, and the like. The CPU 31 is the main controller. The ROM 32 stores various programs. The RAM 33 loads programs and various data. The memory unit 34 stores various programs. The CPU 31, the ROM 32, the RAM 33, and the memory unit 34 are connected to one another via a bus 35. The CPU 31, the ROM 32, and the RAM 33 constitute a control unit 300. That is, the control unit 300 executes the control processing of the payment device 1, which will be described later, by the CPU 31 operating in accordance with the control program stored in the ROM 32 or the memory unit 34 and loaded in the RAM 33.

[0025] The RAM 33 includes a product information section 331. The product information section 331 stores product information of products that have been registered.

[0026] The memory unit 34 is composed of a hard disk drive (HDD), flash memory, etc., and maintains its stored contents even when power is cut off. The memory unit 34 includes a control program unit 341 and a product master 342. The control program unit 341 stores a control program for controlling the payment device 1. The product master 342 stores product information and the weight of each product for each product code that identifies the product. The product master 342 will be described later with reference to FIG. 3.

[0027] The control unit 300 is connected to the display unit 41, operation unit 42, reading unit 43, light-emitting unit 44, weighing unit 45, printer 46, and card reader 47 via the bus 35 and controller 36. The display unit 41 is composed of, for example, a liquid crystal display, and displays product information, etc., to the customer operating the payment device 1. The operation unit 42 is a touch keyboard provided on the display unit 41, including a start button 421 and an end button 422. The start button 421 is operated by the customer to start the registration operation using the payment device 1. The end button 422 is operated by the customer to end the registration operation using the payment device 1 and move on to the payment operation. The printer 46 prints product information and payment information and issues a receipt during the payment process. The card reader 47 is used when making payments other than with cash, such as by credit card or electronic money.

[0028] The control unit 300 is also connected to a communication interface (I / F) 50 via a bus 35. The communication interface 50 is connected to a store server (not shown) installed in the store via a communication line L to send and receive information. The control unit 300 is also connected via the bus 35 to a timer 38 that measures time.

[0029] Next, the product master 342 will be described. The product master 342 has a product code section 3421, a product name section 3422, a price section 3423, and a weight section 3424. The product code section 3421 stores a product code that identifies a product. In the example of FIG. 3, the product code section 3421 stores product codes for all products sold in the store, such as product code "AAAA" that identifies product A, product code "BBBB" that identifies product B, product code "CCCC" that identifies product C, and product code "DDDD" that identifies product D.

[0030] The product name section 3422 stores the product name in association with the product identified by each product code stored in the product code section 3421. The price section 3423 stores the price (unit price) in association with the product identified by each product code stored in the product code section 3421.

[0031] The weight section 3424 stores the weight of a product corresponding to the product identified by each product code stored in the product code section 3421. The weight stored in the weight section 3424 is basically data indicating the weight of the product, but it is desirable to store the weight data stored in the weight section 3424 with a certain tolerance, taking into account slight variations in the weight of each individual product and slight variations in weight due to the weighing environment. If the weight measured by the weighing section 45 is within the tolerance range of the weight stored in the weight section 3424, the control section 300 determines that the weight measured by the weighing section 45 matches the weight stored in the weight section 3424.

[0032] Next, we will explain the functional control of the payment device 1. Figure 4 is a functional block diagram showing the functional configuration of the payment device 1. The control unit 300 functions as a determination unit 301 and a light emission control unit 302 by following a control program stored in the ROM 32 or memory unit 34 and expanded in the RAM 33.

[0033] The determination means 301 uses the weighing data measured by the weighing unit 45 to determine whether the product read by the reading unit 43 has been bagged. Specifically, the determination means 301 compares the weighing data measured by the weighing unit 45 with the weight data of the product read by the reading unit 43 stored in the weight unit 3424, and if the two weights match, it determines that the product read by the reading unit 43 is the product that has been placed in the bag. If the two weights do not match, it determines that the product read by the reading unit 43 is not the product that has been placed in the bag.

[0034] The light emission control means 302 causes the light emitting unit 44 to emit blue light (first form) when it determines that the product read by the reading unit 43 is packaged, and causes the light emitting unit 44 to emit red light (second form different from the first form) when it determines that the product read by the reading unit 43 is not packaged.

[0035] In addition, if the weighing unit 45 does not weigh the item even after a predetermined time has elapsed since the reading unit 43 read the symbol, the light emission control means 302 causes the light emission unit 44 to flash red (third mode) which is different from the first mode and the second mode.

[0036] Next, the control of the payment device 1 will be described. FIG. 5 is a flowchart showing the control process of the payment device 1. As shown in FIG. 5, the control unit 300 of the payment device 1 determines whether the start button 421 has been operated (S11). If it is determined that the start button 421 has been operated (Yes in S11), the control unit 300 performs a zero-point correction to set the weighing data of the weighing unit 45 at this time to 0 grams (S12). Then, the light-emission control means 302 causes the light-emitting unit 44 to emit blue light (first mode) (S13). Then, the control unit 300 executes a product registration process for the product whose symbol was read in S21 (S14). Then, the control unit 300 ends the process and returns to S11.

[0037] Furthermore, if it is determined that the start button 421 has not been operated (No in S11), the control unit 300 determines whether the reading unit 43 has read a symbol (S21). If it is determined that the reading unit 43 has read a symbol (Yes in S21), the light emission control means 302 causes the light emitting unit 44 to emit a blinking blue light (S22). The light emission control means 302 causes the light emitting unit 44 to emit a blinking blue light as a message urging the customer to place the product, whose symbol has been read, into a bag so that the product can be weighed.

[0038] Next, the control unit 300 determines whether the weighing unit 45 has detected a change in weight (S23). If the weighing unit 45 has detected a change in weight, the control unit 300 determines that a product has been placed in a bag. If the control unit 300 determines that the weighing unit 45 has detected a change in weight (Yes in S23), the control unit 300 reads the weight data of the product stored in the weight unit 3424 based on the product code of the product acquired based on the symbol read in S21 (S24). The determination means 301 then compares the read weight data with the changed weight data (i.e., the increased weight data) and determines whether the two weight data match (S25). If the determination is that the two weight data match (Yes in S25), the light emission control means 302 causes the light emitting unit 44 to emit blue light (first mode) (S13) and executes the product registration process (S14).

[0039] On the other hand, if it is determined that the read weight data and the changed weight data do not match (No in S25), it is determined whether the weight measured by the weighing unit 45 is fluctuating periodically (whether chattering is occurring) (S31). For example, if a customer puts an item into a bag with force, the weighing unit 45 may vibrate, causing the weight being measured to fluctuate periodically. Therefore, if it is determined that the weight being measured by the weighing unit 45 is fluctuating periodically (Yes in S31), the control unit 300 waits a predetermined time for the chattering to subside (S32). Thereafter, the determination means 301 compares the read weight data with the changed weight data and determines whether the two weight data match (S33).

[0040] If it is determined that the weight data matches (Yes in S33), the light-emission control means 302 causes the light-emitting unit 44 to emit blue light (first mode) (S13). If it is determined that the read weight data and the changed weight data still do not match (No in S33), the light-emission control means 302 causes the light-emitting unit 44 to emit red light (second mode) (S34). In this case, the product whose symbol was read in S21 may be different from the product placed in the bag. Therefore, the control unit 300 causes the light-emitting unit 44 to emit red light to indicate a warning (S34). The control unit 300 then stops the customer's operation and displays an error message on the display unit 41, instructing the customer to call a store clerk, for example (S35). The payment device 1 stops processing at S35. When a store clerk comes and clears the error, the control unit 300 ends processing and returns to S11.

[0041] Furthermore, if it is determined in S31 that chattering has not occurred (No in S31), there is a possibility that the product whose symbol was read in S21 and the product placed in the bag are different products, so the light emission control means 302 causes the light emitting unit 44 to light up in red to indicate a warning (S34), and then executes the process of S35.

[0042] Furthermore, if it is determined in S23 that the weighing unit 45 has not detected a change in weight (No in S23), it is determined that the product whose symbol was read in S21 has not yet been placed in the bag, and the process waits for a first predetermined time measured by the timer 38. The control unit 300 then determines whether the first predetermined time has elapsed (S41). Until the first predetermined time has elapsed (No in S41), the process returns to S23 to determine whether the weighing unit 45 has detected a change in weight. If it is determined that the first predetermined time has elapsed (Yes in S41), the product has not yet been placed in the bag, and the light-emission control means 302 causes the light-emitting unit 44 to flash red (third mode) (S42). The flashing red light of the light-emitting unit 44 in S42 is a message (not a warning) strongly urging the customer to place the product in the bag. The control unit 300 then displays a message strongly urging the customer to place the product in the bag on the display unit 41 (S43).

[0043] Next, the control unit 300 determines whether a second predetermined time has elapsed (S44). The second predetermined time begins timing at the same time as the first predetermined time, but is longer than the first predetermined time. In other words, the second predetermined time is the time that a predetermined amount of time has elapsed since the first predetermined time elapsed. Until the second predetermined time has elapsed (No in S44), the process returns to S23 to determine whether the weighing unit 45 has detected a change in weight. If it is determined that the second predetermined time has elapsed (Yes in S44), it determines that no product has been placed in the bag since the symbol was read in S21, and the light-emission control means 302 lights the light-emitting unit 44 in red to indicate a warning (S34). Then, the process of S35 is executed.

[0044] Furthermore, if it is determined in S21 that the reading unit 43 has not read the symbol (No in S21), the control unit 300 determines whether the end button 422 has been operated (i.e., whether a payment operation has been performed) (S51). If it is determined that the end button 422 has been operated (Yes in S51), the control unit 300 turns off the light-emitting unit 44 (S52). Then, the control unit 300 executes the payment process based on the product information stored in the product information unit 331 (S53). Then, the control unit 300 ends the process and returns to S11.

[0045] As described above, the payment device 1 of the embodiment comprises a reading unit 43 that reads a symbol attached to a product, a bagging unit 18 that is located near the reading unit 43 and bags the product whose symbol has been read by the reading unit 43, a weighing unit 45 that weighs the bagged product, a light-emitting unit 44 that is provided in the bagging unit 18 within the field of view of the operator who bags the product, a determination means 301 that determines whether the product read by the reading unit 43 has been bagged using weight data measured by the weighing unit 45, and an emission control means 302 that causes the light-emitting unit 44 to emit light in a first form when it is determined that the product read by the reading unit 43 has been bagged, and causes the light-emitting unit 44 to emit light in a second form different from the first form when it is determined that the product read by the reading unit 43 has not been bagged.

[0046] In the payment device 1 of this embodiment, a light-emitting unit 44 is provided in the bagging unit 18 within the field of view of the operator who bags the items, and the light-emitting control means 302 causes the light-emitting unit 44 to emit light in a first mode when it determines that the item read by the reading unit 43 has been bagged, and causes the light-emitting unit 44 to emit light in a second mode different from the first mode when it determines that the item read by the reading unit 43 has not been bagged. This makes it easy for the operator to confirm the light emitted by the light-emitting unit 44.

[0047] Although an embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be embodied in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. This embodiment and its modifications are included within the scope and spirit of the invention, and are also included in the inventions described in the claims and their equivalents.

[0048] For example, in the embodiment, the light-emitting unit 44 is provided at a corner 48 of the bagging unit 18. However, the present invention is not limited to this, and the light-emitting unit 44 may be located in any position on the bagging unit 18 that does not interfere with the bag when the bag is hung on the bagging tool 13 (a position where the light-emitting unit 44 can be visually confirmed). For example, as shown in the modified example of FIG. 6 , the light-emitting unit 44 may be located on the bagging unit 18 in a position where it is not obscured by the bag hung on the bagging tool 13 (for example, in front of the reading unit 43). By providing the light-emitting unit 44 in a position in front of the reading unit 43, it is possible to make it more difficult for an operator to place a product whose symbol has been read by the reading unit 43 in a position in front of the reading unit 43 on the bagging unit 18 (i.e., on top of the light-emitting unit 44). If a product is placed in a position in front of the reading unit 43, there is a risk that the reading unit 43 will read the symbol of the product again (read twice). However, by providing the light-emitting unit 44 in a position in front of the reading unit 43, it is difficult to place a product in a position in front of the reading unit 43, so double reading of the product can be prevented.

[0049] In the embodiment, in the process of S22, the light emission control means 302 causes the light emitting unit 44 to flash in blue. However, this is not limiting, and for example, in the process of S22, the light emission control means 302 may cause the light emitting unit 44 to light up in blue.

[0050] Furthermore, in the embodiment, in the processing of S42, the light-emission control means 302 causes the light-emitting unit 44 to flash in red as the third mode. However, this is not limiting, and for example, in the processing of S42, the light-emission control means 302 may cause the light-emitting unit 44 to flash in blue as the third mode. This is because if the determination in S44 is No, it is not yet necessary to determine that the payment apparatus 1 is in error, and therefore in S42 the light-emitting unit 44 may be displayed in blue rather than red, which indicates a warning.
