  Hereinafter, an example of the embodiment will be described with reference to the drawings. In the present embodiment, a POS (point-of-sale) terminal device will be described as an example of the product data processing device.

  FIG. 1 is a block diagram showing a main configuration of a POS terminal device 100 according to the present embodiment.

  The POS terminal device 100 includes a central processing unit (CPU) 1, a read-only memory (ROM) 2, a random-access memory (RAM) 3, an auxiliary storage unit 4, a clock unit 5, a mode switch 6, and a drawer opening unit 7. , Input / output port (I / O) 8, scanner 9, scanner controller 10, keyboard 11, keyboard controller 12, operator display 13, display controller 14, customer display 15, display controller 16, card reader 17, card A reader controller 18, a printer 19, a printer controller 20, and a communication device 21 are included. Each of these units is connected to the system bus 22.

  The CPU 1 controls each unit to implement various operations as the POS terminal device 100 based on the operating system, middleware, and application program stored in the ROM 2 and the RAM 3.

  The ROM 2 stores the above operating system. The ROM 2 may store the above middleware and application programs. The ROM 2 may store data that is referred to when the CPU 1 performs various processes.

  The RAM 3 stores data to be referred to when the CPU 1 performs various processes. Further, the RAM 3 is used as a so-called work area in which data temporarily used when the CPU 1 performs various processes is stored. A part of the storage area of the RAM 3 is used as a product list area. The RAM 3 may store the above middleware and application programs.

  FIG. 2 is a diagram schematically showing an example of the structure of the product list area.

  As shown in FIG. 2, the product list area is provided with a plurality of data fields for storing information relating to price look-up (PLU) codes, departments, product names, prices, and quantities in association with each other. Thus, at least information on department, product name, price and quantity can be stored in the product list area in correspondence with the PLU code.

  The auxiliary storage unit 4 is, for example, a hard disk drive or an SSD (solid state drive), and stores data used when the CPU 1 performs various processes and data generated by the processes in the CPU 1. The data stored in the auxiliary storage unit 4 includes a PLU file and rate information. The PLU file describes information about products (goods or services) sold or provided at a store where the POS terminal device 100 is used. The rate information represents a rate between a first currency described later and a second currency different from the first currency. The auxiliary storage unit 4 may store the above middleware and application programs.

  The application program stored in the ROM 2, RAM 3 or auxiliary storage unit 4 includes a receipt issuance program described with respect to a receipt issuance process described later. When this receipt issuing program is stored in the RAM 3 or the auxiliary storage unit 4, the transfer of the POS terminal device 100 is generally performed in a state where the receipt issuing program is stored in the RAM 3 or the auxiliary storage unit 4. However, the POS terminal device 100 is transferred in a state where the receipt issuance program is not stored in the RAM 3 or the auxiliary storage unit 4, and is recorded on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, or a semiconductor memory. Alternatively, the receipt issuing program may be transferred via a network, and the receipt issuing program may be written in the RAM 3 or the auxiliary storage unit 4 of the separately transferred POS terminal device 100.

  FIG. 3 is a diagram schematically showing an example of the PLU file.

  The PLU file shown in FIG. 3 includes at least department, product name, and price information corresponding to the PLU code. The PLU code is a code assigned to each product so that they can be uniquely identified. The department is the name or code of the department to which the product identified by the associated PLU code belongs. The product name is the name of the product identified by the associated PLU code. The price is the price of the product identified by the associated PLU code. This price is expressed in the currency defined as the first currency. The first currency is generally a currency in a region where the POS terminal device 100 is used. That is, the first currency in the POS terminal device 100 used in Japan is set to Japanese yen, and the price in the PLU file is expressed in Japanese yen. The PLU file may include other arbitrary information.

  The clock unit 5 constantly performs a timekeeping operation, and generates date / time information representing the date and time.

  The mode switch 6 detects the direction of the keyhole that can be rotated by a specific key, and outputs the detection result as a mode signal. A business mode is assigned to each direction of the keyhole, and the mode signal is a signal indicating which of these operation modes is selected. The business mode includes each mode such as registration, inspection, and checkout. Incidentally, in the registration mode, when a PLU code is input by the scanner 9 or the keyboard 11, data processing related to the sale or provision of the product identified by this PLU code is performed. In the inspection mode, sales summary data obtained from the merchandise sales data generated by the processing in the registration mode is output as a report. In the checkout mode, the sales summary data is cleared after outputting the sales summary data in the same manner as in the inspection mode.

  The drawer opening unit 7 automatically opens the drawer.

  The input / output port 8 converts a mode signal output from the mode switch 6 into mode data and writes it into the RAM 3 or a drive signal for driving the drawer opening unit 7 in response to an instruction to open the drawer from the CPU 1. Output to the drawer opening unit 7.

  The scanner 9 reads a barcode printed on a product. The scanner 9 can include either a fixed type or a handy type, or both.

  The scanner controller 10 controls the operation of the scanner 9 under the control of the CPU 1 and writes the scan data generated by the scanner 9 into the RAM 3.

  The keyboard 11 includes a large number of keys such as a numeric input key, a product designation key (PLU key), and a function key, and a switch that detects pressing of the large number of keys. In response to the key being pressed, the keyboard 11 outputs a command corresponding to the key.

  The keyboard controller 12 controls the operation of the keyboard 11 under the control of the CPU 1 and writes a command output from the keyboard 11 into the RAM 3.

  The operator display 13 is an LCD (liquid crystal display), for example, and can display an arbitrary image under the control of the CPU 1. The operator display 13 is used to display an image representing various information to be presented to the operator.

  The display controller 14 controls the operation of the operator display 13 under the control of the CPU 1.

  The customer display 15 is an LCD or a fluorescent display device, for example, and can display an arbitrary image under the control of the CPU 1. The customer display 15 is used to display an image representing various information to be presented to the customer.

  The display controller 16 controls the operation of the customer display 15 under the control of the CPU 1.

  The card reader 17 reads card information recorded on the payment card. The payment card is a card for making payment without using cash, and may include a credit card, a debit card, a prepaid card, a UnionPay card, and the like.

  The card reader controller 18 controls the operation of the card reader 17 under the control of the CPU 1 and writes the card information output from the card reader 17 into the RAM 3.

  The printer 19 is, for example, a thermal printer or a dot impact printer, and prints a receipt.

  The printer controller 20 controls the operation of the printer 19 under the control of the CPU 1.

  The communication device 21 communicates with the server 300 via a communication network 200 such as a LAN (local area network) or the Internet.

  The server 300 has a so-called store server provided in the same store where the POS terminal device 100 is installed, or a headquarters that generalizes a plurality of stores including the same store where the POS terminal device 100 is installed. It is a so-called headquarter server provided. The server 300 aggregates product sales data generated by the POS terminal device 100 and other POS terminal devices (not shown), and manages data used by each POS terminal device. The server 300 holds a PLU file and rate information for distribution to the POS terminal device 100 and other POS terminal devices.

  Next, the operation of the POS terminal device 100 configured as described above will be described.

  The PLU file is updated by the server 300 in principle. The latest PLU file is distributed from the server 300 to the POS terminal device 100 and other POS terminal devices as necessary. Thus, the PLU file distributed from the server 300 is received by the communication device 21 and written to the auxiliary storage unit 4 under the control of the CPU 1. At this time, the old PLU file stored in the auxiliary storage unit 4 is invalidated by being deleted.

  On the other hand, the CPU 1 starts rate information update processing as shown in FIG. 4 at a predetermined timing. The timing for starting the rate information update process may be arbitrary. For example, when the business mode is newly set to the registration mode, the date and time indicated by the date and time information output from the clock unit 5 is a predetermined date and time. It is conceivable that the update of the rate information is notified from the server 300 or the update of the rate information is requested by the operator.

  In step Sa1, the CPU 1 requests the server 300 to transmit rate information. In response to this request, the server 300 transmits the held rate information to the POS terminal device 100 via the communication network 200.

  In step Sa2, the CPU 1 causes the communication device 21 to receive the rate information transmitted from the server 300 as described above.

  In step Sa <b> 3, the CPU 1 writes the rate information received by the communication device 21 in the auxiliary storage unit 4. At this time, the CPU 1 invalidates the old rate information already stored in the auxiliary storage unit 4 by, for example, overwriting it with new rate information.

  In the present embodiment, it is assumed that the first currency is the Japanese yen, and the rate information indicates the rate between the Japanese yen and the Chinese yuan.

  FIG. 5 is a flowchart of the CPU 1 when the registration mode is set. When the mode switch 6 detects that the business mode is set to the registration mode with the key, the CPU 1 starts the process shown in FIG.

  If the barcode of the product is read by the scanner 9 or the PLU code is input by an operation such as pressing the PLU key on the keyboard 11, the input PLU code is stored in the scanner controller 10 or the keyboard. The data is written into the RAM 3 by the controller 12. Therefore, in step Sb1, the CPU 1 determines whether or not the PLU code is input by checking whether or not the PLU code written as described above is written in the RAM 3, for example. If it cannot be confirmed that the PLU code has been input (NO in step Sb1), the CPU 1 repeats step Sb1. If it is confirmed that the PLU code has been input (YES in step Sb1), the CPU 1 proceeds from step Sb1 to step Sb2.

  In step Sb2, the CPU 1 acquires the PLU code written in the RAM 3 and the information associated therewith from the PLU file stored in the auxiliary storage unit 4 as described above. Then, the CPU 1 additionally stores the acquired PLU code, department, product name, and price information in the product list area of the RAM 2. At this time, the CPU 1 stores “1” as the quantity of the same data record.

  In steps Sb3 to Sb5, the CPU 1 waits for a user operation. Specifically, the CPU 1 is provided in the keyboard 11 in step Sb5j, whether or not a new PLU code is input in step Sb3, and whether or not a quantity relating to the previously input PLU code is specified in step Sb4. It is determined whether or not a subtotal key that is one of the function keys is pressed. Then, when any of Steps Sb3 to Sb5 is NO, the CPU 1 repeats Steps Sb3 to Sb5.

  If a new PLU code is input here (YES in step Sb3), the CPU 1 proceeds from step Sb3 to step Sb2, and the newly input PLU code and the department, product name, and price associated therewith are entered. Each information is additionally stored in the product list area of the RAM 2. However, if the same PLU code is already stored in the product list area, the quantity associated with the PLU code is increased by one. After this, the CPU 1 returns to the standby state of steps Sb3 to Sb5.

  By the way, in order to register a plurality of products for which a PLU code has already been input, if the operator designates a quantity by operating the numeric input key or the like on the keyboard 11 (YES in step Sb4), the CPU 1 accordingly performs steps from step Sb4 to step Sb4. The process proceeds to Sb6, and the quantity associated with the PLU code input immediately before is changed according to the designated quantity. Specifically, the quantity associated with the PLU code input immediately before is changed to a value obtained by adding a value obtained by subtracting one from the designated quantity. Thereafter, the CPU 1 returns to the standby state of steps Sb3 to Sb5.

  If the subtotal key is pressed (YES in step Sb5), the CPU 1 proceeds from step Sb5 to step Sb7. In step Sb7, the CPU 1 calculates the purchase amount in the first currency. Specifically, the CPU 1 calculates the amount of money for each product by multiplying each of the PLU codes stored in the product list area by the price and quantity associated with the PLU code, and further determines in this way. The purchase price is calculated as the sum of the price for each product. Since the price of the PLU file is expressed in the first currency, the purchase price obtained by the above calculation is expressed in the first currency. The CPU 1 stores the purchase amount in the RAM 3.

  In step Sb8, the CPU 1 determines whether the purchase amount is to be settled by cash or a settlement card based on designation by the operator. If payment is to be made with cash, the CPU 1 moves from step Sb8 to step Sb9, and executes cash payment processing in a well-known procedure.

  On the other hand, if payment is to be made with a card, the CPU 1 proceeds from step Sb8 to step Sb10. In step Sb10, the CPU 1 instructs the card controller 18 to acquire the card information recorded on the payment card and store the card information in the RAM 3. In step Sb11, the CPU 1 executes a card payment process according to a well-known procedure based on the card information stored in the RAM.

  If the cash settlement process at step Sb9 or the card settlement process at step Sb11 is completed, the CPU 1 proceeds to step Sb12 in any case. In step Sb12, the CPU 1 performs a receipt issuing process. This receipt issuing process is executed based on the above-described receipt issuing program.

  FIG. 6 is a flowchart in the receipt issuing process of the CPU 1.

  In step Sc1, the CPU 1 confirms whether cash settlement processing or card settlement processing has been performed. If the cash settlement process has been performed, the CPU 1 proceeds from step Sc1 to step Sc2. In step Sc2, the CPU 1 instructs the printer controller 20 to print a receipt (hereinafter referred to as a cash receipt) in which the contents of the cash settlement are expressed in various amounts only in the first currency. In response to this instruction, the printer controller 20 controls the printer 19 to print a cash receipt.

  On the other hand, if the card payment process is performed, the CPU 1 proceeds from step Sc1 to step Sc3. In step Sc3, the CPU 1 determines whether or not the payment card used for payment is a UnionPay card based on the card information stored in the RAM 3. If the card is not a UnionPay card (NO in step Sc3), the CPU 1 proceeds from step Sc3 to step Sc4. In step Sc4, the CPU 1 instructs the printer controller 20 to print a receipt (hereinafter referred to as a card receipt) in which various amounts are expressed only in the first currency. In response to this instruction, the printer controller 20 controls the printer 19 to print a card receipt.

  If the payment card used for payment is a UnionPay card (YES in step Sc3), the CPU 1 proceeds from step Sc3 to step Sc5.

  In step Sc5, the CPU 1 reads rate information from the auxiliary storage unit 4. In step Sc6, the CPU 1 calculates the purchase amount in Chinese yuan from the rate indicated in the rate information read in step Sc5 and the purchase amount in the first currency stored in the RAM 3.

In step Sc7, the CPU 1 represents a receipt (hereinafter referred to as a UnionPay receipt) representing the contents of the payment using the payment card including the purchase amount calculated in step Sc6 and the rate indicated in the rate information read in step Sc5. ) To the printer controller 20 to print. In response to this instruction, the printer controller 20 controls the printer 19 so as to print the billet receipt.

  If the receipt has been printed in any of steps Sc2, Sc4, and Sc7, CPU 1 ends the receipt issuing process. When the receipt issuing process ends, the CPU 1 proceeds to step Sb13 shown in FIG.

  In step Sb13, the CPU 1 performs post-processing such as clearing the commodity list area of the RAM 3 and deleting the purchase price stored in the RAM 3. Then, the CPU 1 returns to the standby state in step Sb2 and prepares for processing for the next customer.

  FIG. 7 is a diagram showing an example of a silver hammer receipt. In FIG. 7, area A1 is an area representing the purchase price and rate expressed in Chinese yuan. The card receipt is, for example, a receipt excluding the area A1.

  As is apparent from the above description, the CPU 1 functions as the following first to sixth processing means by performing processing based on the application program.

  The first processing means inputs product information for determining an amount in which the price of the product is expressed in the first currency, that is, a PLU code. The second processing means calculates the first settlement amount, that is, the purchase amount in Japanese yen, as the sum of the amounts determined based on the product information input until execution of settlement is requested. Note that the first and second processing means described above perform processing for obtaining the first settlement amount as a result, and the first and second processing means obtain the first settlement amount. It can be said that the processing means is configured. The third processing means determines whether or not the payment card is a specific card (here, a UnionPay card) based on the card information read from the payment card by the card reader 17. The fourth processing means, when the payment card is a specific card, displays rate information representing a rate between the second currency and the first currency used in the issuing area of the specific card. Read from 4. The fifth processing means calculates the second settlement amount, that is, the purchase amount in Chinese yuan, by converting the first settlement amount at the rate indicated by the read rate information. The sixth processing means controls the printer 19 to print a receipt displaying the second payment amount calculated by the fifth processing means when the payment card is a specific card.

  As described above, according to the POS terminal device 100, when a payment is made using a UnionPay card, a UnionPay receipt representing the purchase amount in Chinese yuan, which is the currency of the decision issuing region, is issued. The UnionPay card is a payment card issued in the People's Republic of China and is likely to be the currency that the Chinese yuan normally uses for its owner. When a customer who is the owner of a UnionPay card uses a store that uses a currency different from the Chinese yuan as the first currency and makes a payment using the UnionPay card, a UnionPay receipt is issued. Accordingly, the customer can confirm the purchase price in Chinese yuan based on the issued UnionPay receipt.

  Then, the POS terminal device 100 automatically issues a UnionPay receipt if it can be issued. For this reason, the operator does not need to perform any operation related to the issuance of the bill for the silver coin, and the burden on the operator does not increase.

  This embodiment can be variously modified as follows.

  It can also be implemented as another device such as a cash register or a card payment device. When implemented as a cash register, the product unit price is input instead of the product code, and the Japanese settlement amount is calculated as the sum of the product unit prices. In the case of implementing as a card payment apparatus, the payment amount is directly input.

  The display of the rate on the receipt for the silver salmon may be omitted.

  The rate information file or rate information may be acquired from the server 300 every time payment is made.

  The present invention is not limited to the UnionPay card, and can be implemented in the same manner as described above for other payment cards for which the issuing area is specified. Of course, as the rate information in this case, information indicating a rate related to the currency in the issuing area of the target payment card is used.

  Also, rate information is prepared in association with each of a plurality of payment cards, the payment card used is identified and related rate information is acquired, and the purchase amount calculated based on the rate indicated by the rate information is displayed. Receipts can also be issued instead of receipts for UnionPay. In this case, if the rate information is associated with a card brand or the like and the rate information is automatically selected based on the brand of the payment card used, an appropriate receipt according to the customer can be issued. In other words, when relying on the operator to select a currency, the operator must estimate the residential area of the customer and select the currency used in that residential area, so an appropriate currency may not be selected. Many problems may occur, but such problems can be avoided.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
