DETAILED DESCRIPTION

Embodiments provide a settlement processing apparatus capable of detecting all merchandise even when there are multiple radio tags in the communication range of a tag reader.


A settlement processing apparatus according to an embodiment includes a work table with a first holding area on which a first merchandise storage body is placed and a second holding area on which a second merchandise storage body is placed. A first radio tag reader is positioned in the first holding area to read information from a radio tag affixed to an item of merchandise held in the first storage body. A second radio tag reader is positioned in the second holding area to read information from a radio tag affixed to an item of merchandise held in the second merchandise storage body. A processor determines whether a radio tag affixed to an item of merchandise read by the second radio tag reader was already read by the first radio tag reader. The processor generates a list of merchandise held in the second merchandise storage body based on the read information obtained by the first and second radio tag readers, and the determination of whether a radio tag affixed to an item of merchandise read by the second radio tag reader was already read by the first radio tag reader. A display unit displays the generated list.


Hereinafter, an example according to an embodiment will be described with reference to the drawings. FIGS. 1 to 12 show a first embodiment. In the present embodiment, a self-checkout apparatus will be described as an example of a settlement processing apparatus. The self-checkout apparatus according to the present embodiment may also be referred to as a self-checkout type merchandise sales data processing apparatus, a point-of-sale (POS) terminal or a self-registration apparatus. Further, in the present embodiment, it is assumed that settlement is performed with respect to merchandise having different RFID tags storing tag data. The tag data includes a unique tag code and a flag which can indicate two states: ON and OFF. The RFID tag receives a radio signal which requests transmission of the tag data, and in response, transmits the stored tag data in a wireless manner. In addition, the RFID tag receives a radio signal which requests setting the flag to ON, and in response, sets the flag included in the stored tag data to ON. In the present embodiment, the flag included in the tag data is used as a settlement flag for identifying whether or not settlement is completed. The flag is in an OFF state when the merchandise having the RFID tag is attached is displayed in a shop or the like.


FIG. 1 is a perspective view illustrating a plurality (here, three) of self-checkout apparatuses 100 according to the present embodiment, arranged side by side. One self-checkout apparatus 100 may be provided for use, or four or more self-checkout apparatuses 100 may be arranged in parallel for use. The three self-checkout apparatuses 100 each have the same configuration. Thus, here, a configuration of one self-checkout apparatus 100 will be described. The same reference numerals are given to the same portions of the other self-checkout apparatuses 100, and description thereof will be omitted.


The self-checkout apparatus 100 includes a housing 1, a touch panel (which is an example of a display unit) 2, a card reader 4, and a receipt output port 5.

The automatic change machine 30 is normally provided outside the housing 1. The automatic change machine is externally attached to the housing 1 via the change-machine interface 31 of the housing 1 as necessary. Further, a human detection sensor 36 which is attached to, for example, the housing 1 and a weight sensor 37 which detects the weight of the merchandise basket 12 (sum of the weight of the merchandise basket 12 itself and the weight of merchandise in the merchandise basket 12) placed on the first holding area 6a are connected to the input port 34.


The CPU 20, the ROM 21, the RAM 22, and the auxiliary memory unit 23 are connected to each other via the bus line 35, and may be provided as a computer.


The CPU 20 corresponds to the main processor of the computer. The CPU 20 controls each unit to realize various operations as the self-checkout apparatus 100 based on an operating system, middleware, and application programs stored in the ROM 21 and the auxiliary memory unit 23.


The ROM 21 corresponds to the non-volatile memory of the computer. The ROM 21 stores the operating system. In some cases, the ROM 21 may store the middleware or the application programs. Further, in some cases, the ROM 21 may store data to be referred to when the CPU 20 performs various processing.


The RAM 22 corresponds to the volatile memory of the computer. The RAM 22 stores data to be referred to when the CPU 20 performs various processing. Further, the RAM 22 is used as a so-called work area for storing data which is temporarily used when the CPU 20 performs various processing. A portion of the memory area of the RAM 22 is used as a tag list area 22a and a write list area 22b. In the tag list area 22a, a read list, which is a list of tag data read from the RFID tag by the first RFID antenna 15 so as to determine merchandise as an object to be settled in the merchandise basket 12, is stored.


FIG. 11 illustrates a registration screen SC1 as an example of a read list displayed on the screen of the touch panel 2. The registration screen SC1 includes an area AR1 for displaying a list of merchandise and a button B1.


The tag data is transmitted from the RFID tag attached to merchandise and is read. The merchandise name, the number, the unit price, the amount of money, the consumption tax category, the check column 41, and the like of the merchandise are displayed in the area AR1 on the registration screen SC1. The button B1 is a graphical user interface (GUI) touched by, for example, a customer who requests starting to move merchandise one by one from the merchandise basket 12 to the shopping bag 13, or a customer who requests starting of settlement.


In the area AR1 of FIG. 11, although information of twelve articles of merchandise is represented, the information is sequentially added and the registration screen is updated each time the corresponding tag data is read. Specifically, the registration screen does not represent any information of merchandise for which the tag data has not been read. The CPU updates the registration screen so as to represent information of the merchandise name “merchandise A” as the first-received tag data. The CPU 20 updates the registration screen so as to represent information of the merchandise name “merchandise B” as the second-received tag data. The CPU 20 repeats the same updating, thereby updating the registration screen SC1 illustrated in FIG. 11 based on the received tag data of the twelve articles of merchandise. Thus, the registration screen is sequentially updated so as to represent progress of reading the tag data. At this time, the check column 41 is created at the same time. In the check column 41, a blank cell 41a is formed at a position corresponding to the merchandise name.


At the initial stage (before starting to move the merchandise one by one from the merchandise basket 12 to the shopping bag 13), the cell 41a in the check column 41 is held in a blank state, for example. After starting to move the merchandise one by one from the merchandise basket 12 to the shopping bag 13, a check such as a mark is displayed in the check column 41 based on the tag data read from the RFID tag by the second RFID antenna 16. The display format of the merchandise displayed on the registration screen may not necessarily include the check column 41. For example, characters of the checked merchandise may be changed from black to red or inversely displayed. That is, the display format of the merchandise is changed from when the tag data is first read by the first RFID antenna to when the tag data is later read by the second RFID antenna.


The write list area 22b, based on the tag data read from the RFID tag by the second RFID antenna 16, includes a write list, which is a list of tag data read from the RFID tag for processing of displaying a check such as a mark in the check column 41 of the merchandise on the registration screen SC1. Although not illustrated, a portion of the memory area of the RAM 22 is used as a merchandise list area.


The auxiliary memory unit 23 corresponds to an auxiliary memory of the computer. The auxiliary memory unit 23 is, for example, a hard disk drive, a solid state drive (SSD), or the like, and holds data which is used in various processing by the CPU 20 and data which is generated in processing by the CPU 20. Further, in some cases, the auxiliary memory unit 23 may store the middleware or the application programs.


The clock unit 24 regularly performs a clocking operation and generates date and time information representing the date and time.


The touch panel controller 25 controls the display on the touch panel 2 under the control of the CPU 20. Further, the touch panel controller 25 transfers information in accordance with a user operation on the touch panel 2, to the CPU 20 via, for example, the RAM 22.


The card reader 26 reads card information recorded on the card by the non-contact type card reader 4. The card may include a settlement card such as a credit card, a debit card, or a prepaid card, a point card, or the like. Further, the card reader 26 may write information of the card.


The card reader controller 27 controls the operation of the card reader 26 under the control of the CPU 20, and transfers the card information output from the card reader 26 to the CPU 20 via the RAM 22.


The printer 28 may be, for example, a thermal printer, a dot impact printer, or the like, and prints a receipt. The printer 28 discharges a receipt from the receipt output port 5.


The printer controller 29 controls the operation of the printer 28 under the control of the CPU 20.


As illustrated in FIG. 13, the automatic change machine 30 includes a coin insertion port 42, a coin discharge port 43, a bill insertion port 44, a bill discharge port 45, and a receipt output port 48. The coin insertion port 42 is an opening for inserting a coin into the inside of the housing 30a of the automatic change machine 30. The coin discharge port 43 is an opening for discharging a coin to the outside of the housing 30a. The bill insertion port 44 is an opening for inserting a bill into the inside of the housing 30a. The bill discharge port 45 is an opening for discharging a bill to the outside of the housing 30a. The automatic change machine 30 receives the coins and the bills inserted from the coin insertion port 42 and the bill insertion port 44, and discharges coins and bills as change from the coin discharge port 43 and the bill discharge port 45 as necessary.


The change-machine interface 31 controls the operation of the automatic change machine 30 under the control of the CPU 20.


The first tag reader 32a may include the first RFID antenna 15, a transmission circuit, and a receiving circuit. The first tag reader 32a has a tag reading space (the first work space 11a on the first holding area 6a) as a reading range, and reads tag data from a RFID tag which exists in the tag reading space.


The second tag reader 32b may include the second RFID antenna 16, a transmission circuit, and a receiving circuit. The second tag reader 32b has a tag reading space (the second work space 11b on the second holding area 6b) as a reading range, and reads tag data from a RFID tag which exists in the tag reading space.


The communication device 33 communicates with other devices such as a merchandise server 201 and a member server 202 via communication network 200 such as a local area network (LAN) or the Internet.


One of the application programs stored in the ROM 21 or the auxiliary memory unit 23 is a control program for causing the CPU 20 to execute control processing to be described later. The control program is typically stored in the ROM 21 or the auxiliary memory unit 23 when installing the self-checkout apparatus 100. However, the self-checkout apparatus 100 may be installed in a state where the control program is not stored in the ROM 21 or the auxiliary memory unit 23, and the control program may be written in a separately-installed auxiliary memory unit 23 of the self-checkout apparatus 100, after being recorded on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, or a semiconductor memory, or being installed via a network.

The button B1 is for specifying that the purchase is a commercial transaction with a shopper who holds a membership card displayed in the display area R2. The button B2 is for specifying that the purchase is a commercial transaction with a shopper who does not hold a membership card displayed in the display area R2.


In the present embodiment, members of a membership service can purchase merchandise, for example, at a reduced unit price. Benefits of the membership service are provided only to a member who holds a membership card. Thus, in a case where a customer is a member but forgets his or her membership card, the membership service is not provided, and the customer has to purchase merchandise at a normal unit price.


The card inquiry screen SC1 inquires whether or not a shopper who requests registration of the purchased merchandise holds a membership card. When the shopper presents a membership card, the button B1 is touched, and data of the membership card is read by the card reader 26. On the other hand, in a case where a shopper does not present a membership card, the button B2 is touched.


After displaying the card inquiry screen SC1, the CPU 20 waits until either of the buttons B1 and B2 is touched (Act 13). In a case where it is detected that the button B1 is touched, the CPU 20 determines that the purchase is a commercial transaction by a member (YES in Act 13). In this case, the CPU 20 sets a membership flag of a membership table to “1” (Act 14). Further, the CPU 20 registers a membership number and accumulated points in the membership table. The membership number is information read from the membership card by the card reader 26. The accumulated points are stored in a membership database in association with the membership number.


FIG. 9 illustrates an example settlement screen displayed on the touch panel 2 of the self-checkout apparatus 100. The settlement screen SC4 includes display areas R21, R22, and R23, and a button B21.


In the display area R21, payment method selection buttons B41, B42, and B43 are displayed. In the display area R22, the total number of articles of merchandise and the total amount of money in a total table 33b are displayed. In the display area R23, the accumulated points in a membership table 31b is displayed. The button B21 is designated for calling a salesperson by a shopper.


In a case where the button B21 is touched, a call signal is transmitted from the settlement processing apparatus to a merchandise registration apparatus as a transmission source of the settlement information via LAN. In the merchandise registration apparatus that received the call signal, for example, a call notification screen is displayed on the touch panel 2. In the call notification screen, information indicating the settlement processing apparatus as a transmission source of the call signal is displayed. Therefore, a salesperson can easily recognize reception of a call from a shopper who operates the corresponding settlement processing apparatus.


The selection button B41 is touched by a shopper who selects cash payment. The selection button B42 is touched by a shopper who selects credit card payment. The selection button B43 is touched by a shopper who selects point payment. That is, the first settlement screen SC4 is a screen for a shopper to select any one payment method from cash payment, credit card payment, and point payment.


The shopper who confirms the first settlement screen SC4 selects any one of available payment methods displayed in the display area R21, and touches the corresponding selection button B41, B42, or B43. In the settlement processing apparatus, a payment operation in accordance with the selected payment method is performed.


The CPU 20 displays the settlement screen SC4, and waits until the selection button B41, B42, or B43 is touched. When the selection button B41, B42, or B43 is touched, the CPU 20 determines that a payment method corresponding to the touched selection button B41, B42, or B43 is selected. The CPU 20 executes settlement processing in accordance with the selected payment method. That is, in a case where the selection button B41 is touched, the CPU 20 executes settlement processing for cash payment. In a case where the selection button B42 is touched, the CPU 20 executes settlement processing for credit card payment. In a case where the selection button B43 is touched, the CPU 20 executes settlement processing for point payment using the accumulated points in the membership table.


In this regard, in the case of a membership transaction in which the membership flag is set to “1”, in the settlement processing, for example, service points are calculated according to the total amount of money. The service points are transmitted to the database server together with the member number of the membership table, and are accumulated for each member by the member database.


FIG. 12 illustrates an example settlement confirmation screen for cash payment displayed on the touch panel 2 of the self-checkout apparatus 100. The settlement confirmation screen SC5 includes a display area R13 and buttons B14 and B15. In addition, the settlement confirmation screen SC5 includes a display area R11 for displaying operation guidance for shoppers. Further, the settlement confirmation screen SC5 displays a salesperson call button B13 at the same position as that of the settlement screen SC4.


In the display area R13, the total amount of money, the amount of money inserted into the automatic change machine 30, and the change amount are displayed. The button B14 is designated for a shopper who does not want to receive a receipt to confirm the contents of settlement. The button B15 is designated for a shopper who wants to receive a receipt to confirm the contents of settlement. In the following description, the button B14 is referred to as a settlement button B14, and the button B15 is referred to as a receipt button B15. In the display area R11, a message prompting a shopper to touch either of the settlement button B14 and the receipt button B15 is displayed.


When the settlement processing is completed, the CPU 20 causes the printer 28 to operate and issue a receipt. After a receipt is issued, the CPU 20 repeats the subsequent processing in the same manner as described above.


The self-checkout apparatus 100 according to the present embodiment includes the first RFID antenna 15 provided on the first holding area 6a of the work table 6, the second RFID antenna 16 provided on the second holding area 6b, and the CPU 20 as a purchased-merchandise detection unit. The merchandise basket 12 in which merchandise before registration is stored is placed on the first holding area 6a, and the shopping bag 13 for storing the purchased merchandise is placed on the second holding area 6b. The first RFID antenna 15 collectively reads information of radio tags which store identification information of merchandise in the merchandise basket 12 on the first holding area 6a. The second RFID antenna 16 reads information of a radio tag of merchandise which is put one by one from the merchandise basket 12 on the first holding area 6a into the shopping bag 13 on the second holding area 6b. Further, the CPU 20 as a purchased-merchandise detection unit detects all of the purchased merchandise stored in the shopping bag 13 based on the read information by the first RFID antenna 15 and the read information by the second RFID antenna 16. Accordingly, for example, even in a case where the purchased merchandise in the merchandise basket 12 is omitted from reading by the first RFID antenna 15, in the operation of putting the purchased merchandise one by one from the merchandise basket 12 on the first holding area 6a into the shopping bag 13 on the second holding area 6b, the purchased merchandise can be read by the second RFID antenna 16 without omission. Therefore, even in a case where multiple radio tags are in a communication range of the tag reader, it is possible to reliably detect all of the merchandise.


In addition, the self-checkout apparatus 100 includes the touch panel 2. A read list of merchandise in the merchandise basket 12 which have been read by the first RFID antenna 15 is displayed on the touch panel 2. Further, on the registration screen of the touch panel 2, the read list, which is a list of tag data collectively read from the RFID tags by the first RFID antenna 15 so as to determine a plurality of merchandise to be settled in the merchandise basket 12 on the first holding area 6a, and the check column 41 are simultaneously displayed. The read list is checked such as displaying a mark in the check column 41, based on the read information which is read by the second RFID antenna 16. Thus, each time a customer moves and puts merchandise one by one from the merchandise basket 12 to the shopping bag 13, it is possible to confirm reading of the merchandise by simply viewing the screen display of the touch panel 2. Therefore, it is possible to reduce a possibility that purchased merchandise to be put into the shopping bag 13 is omitted.


In the present embodiment, although a configuration in which the shopping bag 13 is disposed on the second holding area 6b is adopted, a configuration in which a second merchandise basket is disposed instead of the shopping bag 13 may be adopted. The second merchandise basket with a different structure in color and shape from that of the merchandise basket 12 on the first holding area 6a is used, and thus the second merchandise basket can be distinguished from the merchandise basket 12 that is used before settlement. In addition, even when an electronic tag is used in place of the RFID tag, an embodiment can be implemented in the same manner as in the above-described embodiment.


Further, in the present embodiment, although the merchandise basket 12 and the shopping bag 13 are disposed on the work table 6, an auxiliary table or the like for further expanding the work space may be provided on the work table 6. In this case, it is possible to secure a work space for performing work such as folding merchandise such as clothing.


Furthermore, in the present embodiment, although a configuration in which the presence or absence of a customer is detected by the human detection sensor 36 is adopted, a configuration in which a membership card held by the customer is detected by the first RFID antenna 15 or the second RFID antenna 16 at the same time as detecting the presence or absence of the customer, may be adopted. In this case, when there is a customer in front of the self-checkout apparatus 100, it is possible to identify whether the customer is a member with a membership card or a non-member. Therefore, a guidance screen displayed on the touch panel 2 can be changed depending on whether the customer is a member with a membership card or a non-member. In a case where the customer is a non-member, “Welcome” is displayed on the touch panel 2, and in a case where the customer is a member with a membership card, “Thank you every time” is separately displayed on the touch panel 2. Further, the self-checkout apparatus 100 may further have a function of a scanner, a bar code reader, touch input, and the like.


FIG. 13 is a perspective view illustrating an example self-checkout apparatus 100 according to a second embodiment. The second embodiment is an example in which a detachable automatic change machine 30 is connected to the side of one self-checkout apparatus 100. The detachable automatic change machine 30 is arranged side by side with the self-checkout apparatus 100. In this case, it is possible to independently provide the self-checkout apparatus 100 capable of handling cash.


FIG. 14 is a perspective view illustrating an example self-checkout apparatus 300 according to a third embodiment. The self-checkout apparatus 300 according to the third embodiment does not include the partition wall 8 of the self-checkout apparatus 100. In the self-checkout apparatus 300 according to the third embodiment, it is possible to arrange the first holding area 6a on which the merchandise basket 12 before settlement is placed and the second holding area 6b on which the shopping bag 13 is placed, on one flat plate of the work table 6, side by side. Even in this case, the same effect as that of the self-checkout apparatus 100 according to the first embodiment can be obtained.


According to the embodiments, it is possible to provide a settlement processing apparatus capable of detecting all merchandise even in a case where there are a plurality of radio tags in the communication range of a tag reader.
