DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
[First embodiment]
FIG. 1 is a perspective view showing a checkout system according to a first embodiment of the present invention installed on a store floor and in operation. As shown in the figure, the checkout system 100 includes five product registration devices 10 and six payment devices (automatic payment devices) 20. The product registration device 10 is installed at the product registration counter 11, and the two payment devices 20 are installed at the payment counter 21.

Furthermore, a store controller (not shown) is installed in the backyard of the store where the checkout system 100 is installed. The store controller and each of the five product registration devices 10 and six payment devices 20 of the checkout system 100 are communicably connected via a LAN (Local Area Network), not shown. The store controller is a computer device that records product data files that include data tables regarding products handled by the store. The store controller updates the product data file on a daily basis, for example, depending on the product sales status, purchase status, etc., and supplies it to each of the five product registration devices 10 and the six payment devices 20. Details of the product data file will be described later. The store controller may be part of or connected to a POS (Point Of Sales) system.

The product registration device 10 stores the product identification information of the product (purchased product) purchased by the shopper C, and the gift certificate information of the gift certificate when the shopper C requests to pay using the gift certificate. This is a device that registers product identification information and ticket information according to the operations of an operator S, converts the registered product identification information and ticket information into a two-dimensional code, and prints the code on a checkout receipt.
The product identification information is information that identifies the product and is recorded in a barcode attached, affixed, printed, etc. to the product. The product identification information is, for example, a 13-digit JAN (Japanese Article Number) code.

The gift certificate is a ticket that has monetary value and can be used for payment in the checkout system 100. For example, the gift certificate is a gift certificate, gift certificate, coupon, or service certificate. Gift certificates and gift certificates include, for example, general-purpose tickets such as gift cards issued by credit card companies, etc., and common gift certificates, book cards, stationery coupons, beer coupons, etc. that can be used commonly throughout the country or in a specific region. This includes tickets and original tickets issued by manufacturers, stores, companies, etc. A coupon ticket is, for example, a ticket with a discount amount or a discount amount written thereon. A service ticket is, for example, a ticket stating that a specific quantity of a specific product will be provided free of charge.
In this embodiment, information regarding the available amount of money obtained from the gift certificate in a transaction, the amount of the service target product, etc., and information identifying the type of gift certificate are referred to as gift certificate information. This is payment information used for payment. In particular, gift certificates, discount coupons, and the like constitute all or part of the payment amount, and thus become the purchaser C's payment information.
In addition to gift certificates, the product registration device 10 may be provided with a payment function using a credit card, and credit card payment information may be converted into a two-dimensional code together with product identification information.

The product registration device 10 is installed at the product registration counter 11 so that a shopper C and an operator S stand facing each other with the product registration counter 11 in between. Therefore, when shopper C wishes to use the gift certificate, it is easy for shopper C and operator S, who are standing facing each other, to exchange the gift certificate. Similarly, the operator S and the shopper C can easily exchange accounting receipts printed and output by the product registration device 10.

The payment device 20 reads the two-dimensional code printed on the transaction receipt by the operation of the shopper C who has the transaction receipt, and extracts the two-dimensional code recording information recorded in the two-dimensional code. Then, the payment device 20 determines the product of the product purchased by the shopper C based on the product identification information included in the extracted two-dimensional code record information and the data table of the product data file stored in the payment device 20 in advance. The name and selling price are extracted from the data table, and the total purchase price of the extracted selling price is calculated. The total purchase price is the total sales price of all the products purchased by shopper C.

Moreover, when the two-dimensional code recording information includes gift certificate information, the payment device 20 calculates the total price of the gift certificate based on the gift certificate information. The total amount of gift certificates is the total amount of all gift certificates used by shopper C in the transaction. Note that if the two-dimensional code recording information does not include gift certificate information, the payment device 20 sets the total amount of the gift certificate to 0 yen. Further, the settlement device 20 calculates the requested payment amount or refund amount based on the calculated purchase total amount and gift certificate total amount, respectively. The requested payment amount is the difference (total purchase amount - total gift certificate amount) when the total amount of the gift certificate is less than the total purchase amount. The refund amount is the difference (total amount of gift certificates - total amount of purchases) when the total amount of gift certificates is greater than the total amount of purchases.

Then, the payment device 20 calculates the name of the product purchased by the shopper C, the total amount of the purchase, the total amount of the gift certificate, the requested payment amount or the refund amount, and information that prompts the shopper C to perform the payment operation. Include it in the menu and display it. The settlement device 20 also includes a change machine and processes change for money inserted by the shopper C. Further, after processing the change, the payment device 20 prints and outputs a receipt.

It is preferable that the payment counter 21 is placed at a destination where the shopper C moves from the product display floor via the product registration counter 11. On the store floor shown in FIG. 1, a product registration counter 11 and a payment counter 21 are installed so that a shopper C moves from the left front to the right rear in a perspective view. The shopper C, who has received the checkout receipt printed by the product registration device 10 from the operator S, moves to a desired checkout counter 21 out of the three checkout counters 21, for example, an empty checkout counter 21, and makes checkout. It can be carried out. That is, in the checkout system 100, usable payment devices 20 are not limited to the product registration device 10 that prints the checkout receipt.

Note that the number of product registration devices 10 and the number of settlement devices 20 included in the checkout system 100 are not limited to five or six, but may be determined depending on, for example, the scale and cost of the store. In this embodiment, in order to simplify the explanation, a checkout system 100 including one product registration device 10 and one payment device 20 will be described.

FIG. 2 is a block diagram showing the configuration of the product registration device 10. As shown in FIG. As shown in the figure, the product registration device 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and a scanner section (product identification information registration means) 104. , a display section 105 for clerks, a display section 106 for customers, a hard disk (product data storage means) 107, an operation section 108 for clerks, a communication section 109, a buzzer 110, and a printing section (medium recording means) 111. and have a configuration in which they are connected via a bus 112.

The CPU 101 is a control unit that reads a product registration program stored in the ROM 102, expands it to the RAM 103, and controls the entire product registration device 10 by executing the steps of the expanded product registration program. By executing the product registration program, the CPU 101 generates a two-dimensional Generate code. This two-dimensional code is, for example, a QR code (registered trademark).

As described above, the ROM 102 stores a product registration program to be executed by the CPU 101, and also stores product registration device identification information that is identification information of the product registration device 10. The RAM 103 expands the product registration program read from the ROM 102 by the CPU 101, and stores various variables and data, such as product identification information and gift certificate information, generated when the CPU 101 executes the product registration program.

The scanner unit 104 is a barcode reader that reads barcodes and extracts information recorded in the barcodes. When the barcode attached, affixed, printed, etc. to the purchased product of the shopper C is placed in the barcode reading area of the scanner unit 104 so as to be readable by the operator S's own action, the scanner unit 104 reads the barcode. The product identification information recorded in the read barcode is extracted and stored in the RAM 103.

The clerk display section 105 is a display section that presents information to the operator S, and is, for example, a liquid crystal display device. Each time the scanner unit 104 reads the barcode of a product and stores the product identification information recorded in the barcode in the RAM 103, the CPU 101 combines the product identification information with the data table of the product data file stored in the hard disk 107. Based on this, the product name and sales price of the product are extracted from the data table and supplied to the store clerk display section 105, and the store clerk display section 105 displays the product name and sales price.
In addition, the store clerk display section 105 receives and displays product certificate information generated by the CPU 101 based on an operation signal supplied from the store clerk operation section 108 to the CPU 101 in accordance with the operation of the store clerk operation section 108 by the operator S. do.

The customer display unit 106 is a display unit that presents information to the shopper C, and is, for example, a liquid crystal display device. The customer display section 106 receives, for example, the same information as the clerk display section 105 from the CPU 101 and displays it. The hard disk 107 is a magnetic hard disk device that records product data files supplied from a store controller connected via the communication unit 109. Note that the hard disk 107 may record a product registration program instead of the ROM 102.

The clerk operation unit 108 has a plurality of gift certificate keys for specifying and inputting the type of gift certificate, numeric keys for specifying and inputting numbers representing the amount related to the gift certificate, and a button to confirm that the registration of the purchased product and the registration of the gift certificate have been completed. and a current total key for specifying and inputting information. Note that the present invention is not limited to the current total key, but may be any key that indicates that the registration of purchased products and gift certificate information has been completed, and may also be used as a print key that indicates the start of printing, for example. In other words, the clerk operation section 108 includes payment information registration means.
Further, the clerk operation unit 108 may include a product designation key registered in advance so as to input product identification information of a specific product. According to this, for a specific product, the product registration device 10 registers the product identification information by pressing the product designation key corresponding to the specific product instead of by reading the barcode.

The communication unit 109 is a communication interface for communicating with an external device, and is, for example, a network interface unit connected to a store controller via a LAN.

As shown in the figure, the payment device 20 includes a CPU 201, a ROM 202, a RAM 203, a scanner section (medium reading means) 204, a display section 205, a customer operation section 206, a communication section 207, and a buzzer 208. , a printing unit 209 , and a change machine 210 are connected via a bus 211 .

The CPU 201 is a control unit that reads the accounting program stored in the ROM 202, expands it to the RAM 203, and controls the entire settlement device 20 by executing the steps of the expanded accounting program. By executing the accounting program, the CPU 201 performs payment processing based on two-dimensional code recording information obtained from the two-dimensional code printed on the accounting receipt.

Specifically, the CPU 201 identifies shopper C based on the product identification information read from the two-dimensional code by the scanner unit 204 and stored in the RAM 203, and the data table of the product data file stored in the RAM 203 in advance. The product name and sales price of the purchased product are extracted from the data table, and the total purchase price of the extracted sales prices is calculated. That is, the CPU 201 includes a purchase total amount calculation means.
Further, the CPU 201 calculates the total amount of the gift certificate based on the gift certificate information read from the two-dimensional code by the scanner unit 204 and stored in the RAM 203 . Note that if the information read from the two-dimensional code does not include gift certificate information, the CPU 201 sets the total amount of the gift certificate to 0 yen.

Further, the CPU 201 calculates the requested payment amount or refund amount based on the calculated purchase total amount and gift certificate total amount, respectively. Specifically, for example, the CPU 201 calculates the difference between the total purchase amount and the total gift certificate amount (total purchase amount - total gift certificate amount), and if the difference is 0 or a positive integer, requests payment of the difference. If the difference is a negative integer, the difference is the refund amount. That is, the CPU 201 includes a settlement amount calculation means.

As described above, the ROM 202 stores an accounting program to be executed by the CPU 201, and also stores payment device identification information that is identification information of the payment device 20. The RAM 203 stores product data files supplied from a store controller connected via the communication unit 207. The RAM 203 also stores various variables and data generated by expanding the accounting program read out from the ROM 202 by the CPU 201 and processing the settlement record program by the CPU 201, such as the total purchase amount, total gift certificate amount, payment request amount, etc. It also remembers the refund amount.

The scanner unit 204 is a two-dimensional code reader that reads a two-dimensional code and extracts two-dimensional code recording information recorded in the two-dimensional code. When the two-dimensional code printed on the checkout receipt is readably positioned in the two-dimensional code reading area of the scanner unit 204 by the action of the shopper C, the scanner unit 204 reads the two-dimensional code and reads the two-dimensional code. The product identification information recorded in the code or the product identification information and gift certificate information are extracted and stored in the RAM 203.

The display unit 205 is a display unit that presents information to the shopper C, and is, for example, a liquid crystal display device. The display unit 205 receives from the CPU 201 the product name of the product purchased by the shopper C, the total purchase price, the total gift certificate price, the requested payment amount or the refund amount, and a character string prompting the shopper C to perform the checkout operation. The accounting menu containing the information is supplied and the accounting menu is displayed. Furthermore, the display unit 205 displays information on the payment amount supplied from the CPU 201. The amount to be paid is the amount after the change is processed by the change machine 210 and notified to the CPU 201.

The customer operation unit 206 is a touch panel type input device that is provided in addition to the display unit 205 and generates an operation signal by operating a GUI (Graphical User Interface) operation button displayed on the display unit 205 under the control of the CPU 201. The customer operation unit 206 includes a checkout key that causes the CPU 201 to start the payment process, and a checkout key that causes the change machine 210 to start the change process. That is, the display section 205 and the customer operation section 206 constitute a touch panel type liquid crystal display.

The communication unit 207 is a communication interface that communicates with an external device, and is, for example, a network interface unit that is connected to a store controller via a LAN. The buzzer 208 is a sound generator that generates a confirmation sound or a warning sound. A digitally synthesized sound is generated when customer C performs an incorrect operation.

The printing unit 209 prints and outputs a receipt on a paper medium when the CPU 201 finishes the payment process. The change machine 210 is an automatic change machine equipped with an input port and a discharge port for coins and banknotes. The change machine 210 counts the coins and/or banknotes inserted into the slot by the shopper C, and notifies the CPU 201 of the deposited amount. Further, the change machine 210 withdraws money corresponding to the refund amount and discharges it to the outlet based on the refund amount notified from the CPU 201.

Next, the product data file will be explained. FIG. 4 is a diagram showing the data structure of the product data file. As shown in the figure, the product data file is a file of a data table (product data) that includes records with items such as "product identification information," "product name," and "sales price." be. The item "product identification information" includes information recorded in a barcode that is attached, affixed, printed, etc. to a product. In this embodiment, as described above, the product identification information is a 13-digit JAN code. Therefore, the two upper digits of the product identification information are information for identifying the country code, in-store marking, or the like. The item "product name" includes a character string representing the product name of the product. The item "sales price" includes a number representing the sales price of the product. The primary key in this data table is the item "product identification information."

Next, the gift certificate information will be explained. FIG. 5 is a diagram showing the internal data structure of the gift certificate information. As shown in the figure, the ticket information is, for example, a 13-digit number, where the first two digits are the "identifier", the next two digits are the "type", and the next two digits are the "reserve". , the remaining 7 digits are expressed as the "amount".
The "identifier" is a fixed number commonly applied to gift certificate information, and is a number that does not match the two upper digits of the product identification information. For example, when the product identification information is a JAN code, the "identifier" is a number (for example, "90") that is not included in the country code or in-store marking. “Type” is a number indicating the type of gift certificate, and for example, gift certificate and gift certificate = “01”, coupon = “02”, and service ticket = “03”. “Reserve” is a number that is not used (referenced) by the product registration device 10 and the payment device 20, and is “00”. Note that the number of "type" may be expanded by using "spare" to classify the gift certificate in more detail. The "amount" is a number representing the amount written on the gift certificate, or the amount related to the written product name or service content. For example, for a gift certificate that says "XX Common Gift Certificate ¥1,000," the "amount" is "0001000," and for a coupon that says "△△ Store Coupon 500 yen off." , the "amount" is "0000500".

When the CPU 101 of the product registration device 10 executes the product registration program and registers the product purchased by shopper C and the gift certificate information, the product identification information and the gift certificate information are stored in the RAM 103. be done. FIG. 6 is a diagram schematically showing a memory map of product identification information and gift certificate information stored in the RAM 103. Referring to the same figure and FIG. 4 together, the memory map shown in FIG. This shows that a product with a sales price of "850" and a gift certificate with a type of "gift certificate and gift certificate" and an amount of "1000" are registered.

Next, accounting receipts will be explained. FIG. 7 is an example of a checkout receipt printed by the printing unit 111 of the product registration device 10. As shown in the figure, the accounting receipt 7 includes the printing date and time (“Printed date: May 6, 2010, 14:30:50”) and a transaction identification number that identifies the transaction by Shopper C (“Shopping date”). Cart No. 126''), the number of items purchased (2 items purchased), and a QR code (registered trademark), which is a two-dimensional code, are printed.

Note that when the product registration device 10 also registers gift certificate information in the product registration process, the product registration device 10 may print the gift certificate usage information (in particular, the amount of the gift certificate) regarding the gift certificate on the accounting receipt. In other words, the product registration device 10 stores a fixed form of gift certificate usage information in the RAM 103 for each "type" of the gift certificate information, and based on the information of the "type" and "amount" of the gift certificate information. , the fixed form text with amount information added is printed on the accounting receipt 7 by the printing unit 111. Specifically, for gift certificate information where the "type" is "01" and the "amount" is "0005000," the product registration device 10 stores, for example, "The gift certificate you have received is worth ¥5,000." "It will be used for payment." is printed on the accounting receipt 7.

Next, the operation of the checkout system 100 will be explained separately into a product registration process executed by the product registration device 10 and a settlement process executed by the settlement device 20.
First, the product registration process by the product registration device 10 will be explained. FIG. 8 is a flowchart showing the procedure of the product registration process executed by the product registration device 10. When the CPU 101 reads out the product registration program stored in the ROM 102 and develops it in the RAM 103 and starts executing the developed product registration program, the product registration device 10 starts the product registration process according to the flowchart shown in the figure.

In step S1, when the barcode attached, affixed, printed, etc. to the purchased product of the shopper C is positioned so as to be readable in the barcode reading area of the scanner unit 104 by the operator S's own operation, the scanner unit 104 The barcode is read, the product identification information recorded in the barcode is extracted, and the product identification information is stored in the RAM 103. Note that when there are multiple identical purchased items, when the operator S inputs the number of purchased items by operating the numeric keys on the clerk operation section 108, the clerk operation section 108 inputs a key code representing the number of purchases. is supplied to the CPU 101, and the CPU 101 stores the same number of product identification information as the number of purchases in the RAM 103 based on the supplied key code.

Next, in step S2, the CPU 101 determines whether any one of the plurality of gift certificate keys on the clerk operation section 108 has been pressed. In other words, when a gift certificate is presented by a shopper C who wishes to pay using the gift certificate, the operator S receives the gift certificate from the shopper C, determines the type of the gift certificate, and The user presses the gift certificate key corresponding to the determined type from among a plurality of gift certificate keys provided corresponding to the type of gift certificate. For example, the operator S who receives a gift certificate written as "XX common gift certificate ¥1,000" from the shopper C presses a gift certificate key provided corresponding to the gift certificate and the gift certificate. By this operation, the clerk operation unit 108 supplies the key code of the pressed gift certificate key to the CPU 101, and the CPU 101 takes in the supplied key code and selects the gift certificate and the product corresponding to the gift certificate. It is determined that the ticket key has been pressed. If the CPU 101 determines that the gift certificate key has been pressed (S2: YES), the process moves to step S3; if the CPU 101 determines that the gift certificate key has not been pressed (S2: NO), the process proceeds to step S4. Move on to processing.

In the process of step S3, the CPU 101 uses a predetermined identifier of the gift certificate (e.g., "90") and a predetermined type number (e.g., gift certificate and Gift certificate information is generated based on the gift certificate (“01”) and the numerical code of the amount (for example, “1000”) supplied from the clerk operation unit 108, and this gift certificate information is stored in the RAM 103.

Specifically, if the gift certificate is a gift certificate or gift certificate worth 1000 yen, the CPU 101, for example, inputs "90", which is a predetermined identifier of the gift certificate, and the pressed gift certificate or gift certificate. Based on the predetermined type number “01” corresponding to the associated ticket key and the numerical code “1000” for the amount supplied from the clerk operation unit 108, The product ticket information “9001000001000” shown in FIG. 1 is generated and stored in the RAM 103.
In addition, if the gift certificate is a 500 yen discount coupon, the CPU 101, for example, corresponds to "90", which is the predetermined identifier of the gift certificate, and the gift certificate key associated with the pressed coupon. The product ticket information "9002000000500" shown in FIG. 5 is generated based on "02", which is the type number determined in advance by and stores it in the RAM 103.

Next, in step S4, the CPU 101 determines whether or not the cash total key on the clerk operation section 108 has been pressed. In other words, Operator S must confirm that the product registration of the purchased product by Shopper C has been completed, and if there is a gift certificate that Shopper C wishes to use, the registration of that gift certificate has been completed, or that the When it is confirmed that there is no request for use, the cash count key provided on the clerk operation section 108 is pressed. By this operation, the clerk operation unit 108 supplies the key code of the pressed cash total key to the CPU 101, and the CPU 101 takes in the supplied key code and determines that the cash total key has been pressed. If the CPU 101 determines that the current total key has been pressed (S4: YES), the CPU 101 generates a two-dimensional code based on the purchased product information and gift certificate information stored in the RAM 103, and proceeds to step S5. On the other hand, if the CPU 101 determines that the current total key is not pressed (S4: NO), the process moves to step S1.

In step S5, the CPU 101 inputs the date and time information of the equipped clock, the transaction identification number represented by a number that increases by one for each transaction, the number of purchased products that is the number of product identification information, and the two-dimensional code. is supplied to the printing section 111. The printing unit 111 then prints the supplied information and outputs it as an accounting receipt.

Next, the payment processing by the payment device 20 will be explained. FIG. 9 is a flowchart showing the procedure of the payment process executed by the payment device 20. When the CPU 201 reads out the payment program stored in the ROM 203 and expands it into the RAM 203 and starts executing the developed payment program, the payment device 20 starts the payment process according to the flowchart shown in the figure.
Note that the payment device 20 stores in advance the product data file supplied from the store controller in the RAM 203 before executing the payment processing.

In step S11, when the two-dimensional code printed on the checkout receipt is readably positioned in the two-dimensional code reading area of the scanner unit 204 by the action of the shopper C, the scanner unit 204 reads the two-dimensional code. The two-dimensional code recording information read and recorded on the two-dimensional code is extracted and stored in the RAM 203.
Specifically, for example, the scanner unit 204 reads a two-dimensional code printed on a checkout receipt, and reads the product identification information "4912345678966", "4912345678980" recorded in the two-dimensional code, and the product certificate information. "9001000001000" is extracted and stored in the RAM 203. As a result, the memory map shown in FIG. 6 is developed in the RAM 203.

Next, the CPU 201 extracts product identification information from the two-dimensional code record information stored in the RAM 203, uses the extracted product identification information as a search key, and searches the data table of the product data file stored in the RAM 203 in advance for the product name and sales information. Extract the price. As a method for extracting product identification information, for example, the CPU 201 extracts only data whose upper two digits indicate product identification information from the two-dimensional code recording information stored in the RAM 203. Next, the CPU 201 counts items with the same number of extracted product identification information (however, if there is no item with the same number, the counting result is "1"), and counts each item of product identification information. The result (that is, the number of purchases), product name, and sales price are stored in the RAM 203. Then, the CPU 201 calculates the total sales price and stores it in the RAM 203 as the total purchase price.

Next, in step S12, the CPU 201 searches the two-dimensional code record information stored in the RAM 203 for gift certificate information, and if the gift certificate information is detected (S12: YES), extracts the amount from the gift certificate information. do. As a method for extracting the gift certificate information, for example, the CPU 201 extracts only data in which the upper two digits indicate the gift certificate information from the two-dimensional code record information stored in the RAM 203. Next, the CPU 201 calculates the total amount of the one or more pieces of gift certificate information, stores it in the RAM 203 as the total price of the gift certificate, and proceeds to the process of step S13.
On the other hand, if the CPU 201 does not extract the gift certificate information from the two-dimensional code record information stored in the RAM 203 (S12: NO), the CPU 201 stores the total price of the gift certificate as "0" in the RAM 203, and proceeds to the process of step S24.

In step S13, the CPU 201 calculates the difference between the total purchase amount and the total gift certificate amount stored in the RAM 203 (total purchase amount - total gift certificate amount), and if the difference is "0" or a positive integer (S13 : YES), the difference is stored in the RAM 203 as the requested payment amount, and the process moves to step S14. On the other hand, if the calculated difference is a negative integer (S13: NO), the CPU 201 stores the difference as a refund amount in the RAM 203, and proceeds to step S22.

In step S14, the CPU 201 stores the information stored in the RAM 203, including the name of the product purchased by the shopper C, the number of purchases, the total purchase amount, the total gift certificate amount, and the requested payment amount, as well as the accounting key. The accounting menu (a) including images of GUI operation buttons is supplied to the display unit 205. Then, the display unit 205 displays the accounting menu (a). The checkout key, which is a GUI operation button, has the function of the customer operation section 206.
A display example of the accounting menu (a) displayed by the display unit 205 is shown in FIG. As shown in the figure, in the process of step S14, the display unit 205 displays a menu 50a. On the left side of the menu 50a, the name and number of purchased items by shopper C are displayed for each item, and on the right side of the menu 50a, the total purchase amount, the total gift certificate amount, the requested payment amount, Information including the checkout key 51 and information prompting the user to press the checkout key 51 ("Please press checkout key") is displayed.

In step S15, when the checkout key 51 is touched by the shopper C, the customer operation unit 206 supplies an operation signal indicating that the checkout key 51 has been touched to the CPU 201, and the CPU 201 receives the operation signal. Then, the process moves to step S16.
Next, in step S16, the CPU 201 supplies the display unit 205 with a menu including the requested payment amount stored in the RAM 203 and an image of the GUI operation button of the settlement key. The display unit 205 then displays the menu. The payment key, which is a GUI operation button, has the function of the customer operation section 206.
A display example of the menu displayed on the display unit 205 is shown in FIG. As shown in the figure, in the process of step S16, the display unit 205 displays a menu 60a. The menu 60a displays information including the requested payment amount for the shopper C, a settlement key 61, and information prompting the shopper to press the settlement key 61 ("please insert change into the change machine and press the settlement key"). be done.

Next, in step S17, when the shopper C inserts money corresponding to the requested payment amount into the slot of the change machine 210, the change machine 210 deposits the inserted money and sends the deposited amount to the CPU 201. Notice. Then, the CPU 201 stores the deposited amount in the RAM 203.
Next, in step S18, the CPU 201 supplies the deposited amount stored in the RAM 203 to the display unit 205, and the display unit displays the deposited amount. Specifically, for example, when the deposited amount is "1000", the display unit 205 displays a menu 60b shown in FIG. 12.
Next, in step S19, when the checkout key 61 is touched by the shopper C, the customer operation unit 206 supplies an operation signal indicating that the checkout key 61 has been touched to the CPU 201, and the CPU 201 Upon receiving the signal, the process moves to step S20.

In step S20, which is executed after the process in step S19, the CPU 201 calculates the difference between the payment request amount stored in the RAM 203 and the deposited amount (deposit amount - payment request amount), and determines whether the difference is "0" or correct. If it is an integer (that is, if the amount of change is 0 yen or there is an amount of change), the difference is stored in the RAM 203 as the amount of change. Next, the CPU 201 notifies the change machine 210 of the amount of change. The change machine 210 that has received the notification of the amount of change withdraws the amount of money and discharges it to the outlet. Then, the change machine 210 supplies a notification of completion of change processing to the CPU 201. Next, the CPU 201 supplies the amount of change stored in the RAM 203 to the display unit 205, and the display unit displays the amount of change. Specifically, when the change amount is "500", the display unit 205 displays a menu 70a shown in FIG. 13.

Note that in the process of step S20 above, if the difference calculated by the CPU 201 is a negative integer (that is, if there is a shortage), the difference is used as a new payment, although it is not shown in the flowchart of FIG. The amount is stored in the RAM 203 as the requested amount, and the process returns to step S16.

In step S21, upon receiving the change processing completion notification from the change machine 210, the CPU 201 stores the product name, sales price, number of purchases, total purchase amount, and total purchase price of the product purchased by the shopper C, which are stored in the RAM 203. Receipt description information including information on the deposited amount and the amount of change is supplied to the printing unit 209. Then, the printing unit 209 prints the receipt description information on a paper medium, outputs it as a receipt, and notifies the CPU 201 of printing completion information. Then, the CPU 201 that has received the print completion information ends the process of the flowchart shown in FIG.

If the difference calculated by CPU 201 in the process of step S13 is a negative integer (S13: NO), in step S22, CPU 201 stores the name of the product purchased by shopper C, the number of purchases, and the purchase amount stored in RAM 203. A checkout menu (b) that includes information on the total amount, the total amount of the gift certificate, and the refund amount and also includes an image of the GUI operation button of the checkout key is supplied to the display unit 205. The display unit 205 then displays the accounting menu (b).
A display example of the accounting menu (b) displayed by the display unit 205 is shown in FIG. As shown in the figure, in the process of step S22, the display unit 205 displays a menu 50b. On the left side of the menu 50b, the product name and number of purchased items by shopper C are displayed for each item, and on the right side of the menu 50b, the total purchase amount, the total gift certificate amount, the refund amount, and the checkout amount are displayed. Information including the key 51 and information prompting the user to press the checkout key 51 ("Please press the checkout key") is displayed.

In step S23, when the checkout key 51 is touched by the shopper C, the customer operation unit 206 supplies an operation signal indicating that the checkout key 51 has been touched to the CPU 201, and the CPU 201 receives the operation signal. Then, the process moves to step S20.

In step S20, which is executed after the process in step S23, the CPU 201 notifies the change machine 210 of the refund amount stored in the RAM 203. The change machine 210 that has received the notification of the refund amount withdraws the refund amount and discharges it to the outlet. Then, the change machine 210 supplies a notification of completion of change processing to the CPU 201. Next, the CPU 201 supplies the refund amount stored in the RAM 203 as a change amount to the display unit 205, and the display unit displays the change amount.

If the CPU 201 does not extract the gift certificate information from the two-dimensional code record information stored in the RAM 203 in the process of step S12 (S12: NO), in the step S24, the CPU 201 extracts the product of the purchased product of the shopper C stored in the RAM 203. A checkout menu (c) that includes information such as name, number of purchases, and total purchase amount, as well as an image of the GUI operation button of the checkout key, is supplied to the display unit 205. Then, the display unit 205 displays the accounting menu (c). Then, the process moves to step S15.
A display example of the accounting menu (c) displayed on the display unit 205 is shown in FIG. As shown in the figure, in the process of step S24, the display unit 205 displays a menu 50c. On the left side of the menu 50c, the product name and the number of purchased items by shopper C are displayed for each item, and on the right side of the menu 50c, the total purchase amount, the accounting key 51, and the number of items purchased by shopper C are displayed. (“Please press the checkout key”) and other information will be displayed.

As explained above, according to the first embodiment, when registering the purchased product of the shopper C using the product registration device 10, the operator S registers the information recorded on the barcode attached, affixed, printed, etc. to the purchased product. Only the product identification information and gift certificate information used by shopper C are registered. Then, the shopper C makes a payment using the payment device 20 using the payment receipt on which the product identification information and the gift certificate information are two-dimensionally coded and printed. Therefore, since the shopper C who has completed the registration using the product registration device 10 moves to the desired payment device 20 (for example, an empty payment device 20) and makes payment, the time spent in the product registration device 10 is reduced. As a result, the checkout system 100 can reduce the transaction time without the risk of bottlenecks (large waiting times by shoppers) related to transaction processing by the operator S. Furthermore, since the operator S receives the gift certificate from the shopper C and registers the gift certificate information in the product registration device 10, there is no risk of unauthorized use such as reuse of the gift certificate by the shopper C. Furthermore, since the shopper C does not need to call the operator S or be present when paying using the gift certificate, the checkout process is efficient. Further, since a long waiting time by the shopper C does not occur, there is no need to increase the number of lanes for the product registration device 10, and an increase in personnel costs can be suppressed.
In other words, according to the first embodiment, when making payments using gift certificate information, it is possible to reliably prevent fraudulent use of gift certificates and perform quick and efficient checkout without increasing personnel costs. can.

Further, according to the first embodiment, by using a two-dimensional code as the code printed on the accounting receipt output by the product registration device 10, a large amount of information can be included in the two-dimensional code, so the payment device 20 can be read only once, thereby preventing erroneous accounting and making efficient accounting possible.
Further, according to the first embodiment, the gift certificate information registered in the product registration device 10 is displayed on the display unit 205 of the payment device 20 at the time of payment, so that the shopper C can It is possible to visually confirm that the ticket is certainly used at the time of payment, and the payment can be made quickly without having to worry about reconfirming with the clerk.
Further, in the first embodiment, when the product registration device 10 prints the gift certificate usage information (especially the amount of the gift certificate) on the checkout receipt, the shopper C can Since it can be confirmed before the payment process that the desired amount of the ticket, etc. will be used at the time of payment, prompt payment can be made without having to worry about reconfirming with the clerk.

[Second embodiment]
In the checkout system 100 according to the first embodiment described above, the product registration device 10 converts product identification information and gift certificate information into two-dimensional codes and prints and outputs them on a checkout receipt, and the payment device 20 prints and outputs the checkout receipt for checkout. The two-dimensional code printed on the receipt was read, and payment processing was performed based on the two-dimensional code record information recorded in the two-dimensional code and the data table of the product data file supplied from the store controller.
The second embodiment of the present invention is an example in which the two-dimensional code recording information included in the two-dimensional code recorded on the accounting receipt is different from the first embodiment.

FIG. 16 is a block diagram showing the overall configuration of a checkout system according to a second embodiment of the present invention. As shown in the figure, the checkout system 200 has a configuration in which two product registration devices 10a, two payment devices (automatic payment devices) 20a, and a store controller 30 are connected via a LAN 40. have The configurations of the product registration device 10a and the payment device 20a are the same as those of the product registration device 10 and the payment device 20 in the first embodiment, so a description of their specific configurations will be omitted.
Note that the number of product registration devices 10a and the number of settlement devices 20a included in the checkout system 200 are not limited to two each, but are determined depending on, for example, the scale and cost of the store.

The operation of checkout system 200 will be explained. FIG. 17 is a sequence diagram showing the processing procedure between the product registration device 10a, the payment device 20a, and the store controller 30. First, in step S31, the CPU 101 of the product registration device 10a executes a product registration process similar to the product registration process in the first embodiment, and stores product identification information and gift certificate information in the RAM 103.
Next, in step S32, the CPU 101 generates a transaction identification number that identifies the transaction by the shopper C, and creates a registration data file containing the transaction identification information, the product identification information stored in the RAM 103, and the gift certificate information. is generated and the file data is stored in the RAM 103. The transaction identification information is, for example, a positive integer that increases with each transaction.
Next, the CPU 101 converts the transaction identification information into a two-dimensional code and supplies it to the printing unit 111, which prints the two-dimensional code on a paper medium and outputs it as an accounting receipt.

Next, in step S33, the CPU 101 reads the file data of the registered data file stored in the RAM 103 and supplies it to the store controller 30 from the communication unit 109 via the LAN 40.
In step S34, the store controller 30 imports the registration data file supplied from the product registration device 10a, and then in step S35, the store controller 30 stores the imported registration data file in a storage unit such as a magnetic hard disk device. do.
Next, in step S36, the store controller 30 distributes the registration data file to all payment devices 20a included in the checkout system 200 via the LAN 40.

In step S37, all the payment devices 20a included in the checkout system 200 receive the registration data file through the communication unit 207 and store it in the RAM 203.
Next, in step S38, the payment device 20a that caused the scanner unit 204 to read the two-dimensional code using the accounting receipt printed in the process of step S32 uses the two-dimensional code recording information recorded in the two-dimensional code. The transaction identification information is extracted from the transaction identification information and stored in the RAM 203. Then, the CPU 201 of the payment device 20a identifies the registered data file using the transaction identification information as a search key regarding the transaction identification information stored in the RAM 203 and the file data of the registered data file, and extracts product identification information from the registered data file. Extract the gift certificate information. Next, the CPU 201 executes payment processing in the same manner as in the first embodiment based on the extracted product identification information and gift certificate information.

As explained above, according to the second embodiment, when registering the purchased product of the shopper C using the product registration device 10a, the operator S can record the information in the barcode attached to, affixed to, printed on, etc. the purchased product. Only the product identification information and gift certificate information used by shopper C are registered. Then, the shopper C makes a payment using the payment device 20a using the payment receipt on which the transaction identification information is printed as a two-dimensional code. Therefore, since the shopper C who has completed the registration using the product registration device 10a moves to the desired payment device 20a (for example, an empty payment device 20a) and makes payment, the time spent in the product registration device 10a is reduced. can be shortened. Therefore, the checkout system 200 can shorten the transaction time without the risk of bottlenecks (large waiting times by shoppers) associated with transaction processing by the operator S. Furthermore, since the operator S receives the gift certificate from the shopper C and registers the gift certificate information, there is no risk of unauthorized use such as reuse of the gift certificate by the shopper C. In addition, since the shopper C does not need to call the operator S or be present when paying using the gift certificate, the checkout process is efficient. Further, since a long waiting time by the shopper C does not occur, there is no need to increase the number of lanes for the product registration device 10a, and an increase in personnel costs can be suppressed.
In other words, according to the second embodiment, when making payments using gift certificate information, it is possible to reliably prevent fraudulent use of gift certificates and perform quick and efficient checkout without increasing personnel costs. can.

In the first embodiment described above, the accounting receipt is a paper medium on which a two-dimensional code is printed. In addition to this, an IC card with a built-in IC chip that can write and read data is used in place of a checkout receipt, and the product registration device 10 writes product identification information and gift certificate information on the IC card. The product identification information and gift certificate information may be read out from the IC card on the payment device 20 side and used.
Similarly, the transaction identification information may be written on the IC card on the product registration device 10a side, and the transaction identification information may be read out from the IC card on the payment device 20 side and used.
In addition, when using an IC card, a collection box for the IC card used for the payment process is installed next to the payment device 20.

Further, in the first embodiment, the product registration device 10 and the payment device 20 are not connected online, and the two-dimensional code printed on the accounting receipt 7 records product identification information and gift certificate information. An example was given. In addition to this, for example, all product registration devices 10 and all settlement devices 20 in the checkout system 100 are connected via LAN, and the product registration device 10 sends a transaction identification number, product identification information, and gift certificate for each transaction. Table information in which the information is associated with each other may be distributed to all payment devices 20. In this case, for each transaction, the printing unit 111 of the product registration device 10 converts the transaction identification number of the transaction into a two-dimensional code or barcode and prints it on the accounting receipt. Then, the scanner unit 204 of the payment device 20 acquires the transaction identification number by reading the code printed on the accounting receipt, and the payment device 20 uses the acquired transaction identification number as a search key from the product registration device 10. Product identification information and gift certificate information are acquired from the supplied table information and payment processing is performed.

In addition to directly converting product identification information and payment information into two-dimensional codes and recording them as shown in the first embodiment, the scanner unit 104 of the product registration device 10 also records product identification information and payment information, for example. The key information that can indirectly identify the information may be encoded and recorded. In the case of indirect identification in this way, for example, the product registration device 10 associates the registered product identification information and payment information with key information and transmits it to the payment device 20, and the payment device 20 sends the registered product identification information and payment information to the payment device 20. The unit 204 identifies the product identification information and payment information transmitted from the product registration device 10 by reading the key information recorded on the medium.
Further, for example, the product registration device 10 stores the registered product identification information and payment information in association with key information in the RAM 103, and the payment device 20 uses the scanner unit 204 to read the key information recorded on the medium, The product identification information and payment information stored in the RAM 103 of the product registration device 10 may be referenced based on the key information.

Furthermore, in the first and second embodiments, an example was shown in which the gift certificate information is inputted by operating the numerical keys of the clerk operation unit 108 of the product registration device 10, 10a, but there are other ways to input the gift certificate information, for example. Information regarding the amount of money and the product to be serviced may be printed in the form of a bar code, and the scanner unit 104 may read the bar code of the gift certificate and register the gift certificate information.

Further, in the first and second embodiments, an example was shown in which the payment devices 20 and 20a calculate the total purchase amount, but in addition to this, the product registration devices 10 and 10a calculate the total purchase amount and The total purchase amount may be converted into a two-dimensional code along with the identification information and the gift certificate information. In this case, the payment devices 20, 20a can perform the payment process by acquiring product identification information, gift certificate information, and total purchase price from the two-dimensional code printed on the checkout receipt.

Furthermore, in the first and second embodiments, the payment devices 20 and 20a were provided with a change machine 210 to perform cash payment. In addition to this, the payment devices 20 and 20a may be devices (automatic payment devices) that perform payment using electronic money. Furthermore, the payment devices 20 and 20a may allow the shopper C to select either a cash payment method or an electronic money payment method.

In the second embodiment, when the payment device 20a reads identification information from a medium and performs payment, the CPU 101 refers to the store controller 30 the product identification information and payment information specified by the read identification information. You may also do so. Further, when the payment device 20a reads the identification information from the medium, the payment device 20a sends a command to the store controller 30 requesting the payment device 20a to send the product identification information and payment information corresponding to the identification information. It's okay. Then, the payment device a may take in the product identification information and payment information transmitted from the store controller 30 based on the command and perform the payment process.

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