When the payment apparatus 20 issues a receipt, it prints on the receipt that the receipt has been issued.

  If the customer C does not wish to issue a receipt for the registration process, the checkout device 20 issues a receipt printed with a barcode for issuing a receipt so that the receipt can be issued at a later date. The customer C receives the issued receipt, and causes the settlement apparatus 20 to issue a receipt by reading the code printed on the receipt at a later date.

  FIG. 2 is a block diagram showing a configuration of the POS system 100. The store controller 30 and each product registration device 10a are connected to each other via a LAN (Local Area Network) 40 so that they can communicate with each other. Further, the store controller 30 and each checkout device 20a are communicably connected via the LAN 40.

  Since each product registration device 10a has the same configuration, the product registration device 10a will be referred to as a product registration device 10 below. In addition, since each settlement apparatus 20a has the same configuration, the settlement apparatus 20a is referred to as a settlement apparatus 20 below.

First, the store controller 30 will be described.
The store controller 30 is a computer (server). The store controller 30 stores a product data file. Here, the product data file is a data file including data on products handled by the store, and is, for example, a data file (data table) in which product names (product numbers) and sales prices are associated with each other.

  The store controller 30 also stores a large number of transaction data and transaction numbers associated with the transaction data as log files. Here, the transaction data is data including details of products purchased by customers (purchased products).

  Further, the store controller 30 supplies the product data file updated in accordance with the sales status and purchase status of the product to each product registration device 10 and each checkout device 20 at a frequency of once a day, for example. To do. Moreover, the store controller 30 receives transaction data from the merchandise registration device 10 and stores the received transaction data as a log file. Further, the store controller 30 receives the transaction number from the settlement apparatus 20, acquires transaction data associated with the received transaction number, and returns the acquired transaction data to the settlement apparatus 20 that has transmitted the transaction number.

Next, the product registration device 10 will be described.
The merchandise registration apparatus 10 is operated by an operator S (see FIG. 1) in the registration process, and reads the merchandise data attached to the merchandise purchased by the customer C (see FIG. 1), so that the details of those merchandise are displayed. The transaction data to be included is registered in the store controller 30.

  In addition, in the registration process, the product registration device 10 calculates the total price of the products purchased by the customer based on the transaction data, and prints and discharges information including at least the total price of the purchased products on a paper medium. Issue a checkout slip at In addition, in the registration process, the merchandise registration apparatus 10 issues a checkout slip by printing information on a paper medium and discharging information including whether the receipt is required or not when a customer desires to issue a receipt.

  At this time, the merchandise registration apparatus 10 displays at least information including the total price of the purchased merchandise and information including the necessity of issuing a receipt according to whether the communication status of the store controller 30 is good or not. (Japanese Article Number) code) or two-dimensional code (for example, QR code (registered trademark)).

  Customer C receives the issued checkout slip and causes the checkout device 20 to read the bar code or two-dimensional code printed on the checkout slip, thereby causing the checkout device 20 to execute the payment checkout process and A receipt will be issued accordingly.

  FIG. 3 is a block diagram illustrating a configuration of the commodity registration apparatus 10. The merchandise registration apparatus 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a scanner unit 104, a store clerk display unit 105, and a customer display unit 106. A hard disk 107, a store clerk operation unit 108, a communication unit 109, a buzzer 110, a printing unit 111, and a bus 112. These are connected to each other via a bus 112.

  The ROM 102 stores a product registration program for causing the CPU 101 to execute a product registration process. The ROM 102 stores a device number for identifying the device itself.

  In the merchandise registration process, the scanner unit 104 optically reads the merchandise data attached to the merchandise by the operation of the operator S, and stores the read merchandise data in the RAM 103. Further, the scanner unit 104 optically reads a person-in-charge name (person-in-charge number) for identifying the operator S from a name tag or the like, and stores the read person-in-charge name in the RAM 103.

  A product registration program read from the ROM 102 is expanded in the RAM 103. Further, the RAM 103 temporarily stores various variables and data (for example, product data read by the scanner unit 104, a person in charge name, and transaction identification information) generated by executing the product registration program.

  The RAM 103 temporarily stores transaction data in the processing area. The RAM 103 additionally stores transaction data determined by the product registration process in a log file. The RAM 103 may continue to store the confirmed transaction data, for example, on the transaction day. Further, the RAM 103 may store a product data file supplied from the store controller 30 connected via the communication unit 109.

  The CPU 101 reads the product registration program stored in the ROM 102, expands it in the RAM 103, and executes the steps of the expanded product registration program, thereby controlling the product registration apparatus 10 as a whole.

  When receiving a request from the customer for a receipt during product registration (before registration or before closing), the CPU 101 sets receipt necessity information indicating whether or not a receipt is required. That is, when the receipt issuance is instructed, the receipt necessity flag is set to “1”, and the receipt issuance is set to “0” (setting means).

  Further, the CPU 101 determines a transaction number before causing the printing unit 111 to print a slip. Here, the transaction number is a number composed of the device number of the own device and a unique number (for example, a serial number) determined for each transaction in which the customer C purchases a product. For example, the transaction number is a number “01123” composed of a device number “01” followed by a unique number “123”. The CPU 101 associates transaction data including the details of merchandise purchased by the customer and the necessity of issuing a receipt with the transaction number, and transmits the transaction data to the store controller 30 via the communication unit 109. Thereby, the confirmed transaction data and transaction number are stored in the store controller 30.

  The CPU 101 determines whether or not there is a state in which the settlement apparatus 20 can obtain transaction data by communication. For example, when the communication state between the own device and the store controller 30 is good, the CPU 101 determines that the common operation of the LAN 40 is normal and the payment device 20 can obtain transaction data by communication.

  In addition, when the CPU 101 determines that the transaction apparatus 20 is in a state where transaction data can be obtained by communication, the transaction number is converted into a one-dimensional code such as a barcode, and a settlement in which a barcode representing the transaction number is printed. The slip is issued to the printing unit 111. A one-dimensional code such as a bar code is identification information that can specify transaction data.

  When a one-dimensional code is printed on a checkout slip, a transaction number for identifying transaction data, identification information for identifying a product (for example, JAN code), the number, and receipt necessity information (for example, required: Information such as a receipt is necessary or not: a receipt is not necessary is stored and held in the product registration device 10, the checkout device 20, or the store controller (transaction data management device or server device) 30.

  On the other hand, if the CPU 101 determines that the transaction apparatus 20 cannot obtain transaction data by communication, that is, if the state is not good, the determined transaction data stored in the RAM 103 (requires receipt issuance). Is converted into a two-dimensional code such as a QR code (registered trademark). The CPU 101 controls the printing unit 111 and issues a checkout slip by printing this two-dimensional code on a paper medium.

  The two-dimensional code such as a QR code (registered trademark) may be only identification information that can specify transaction data, but in addition to the identification information, usually, identification information that can specify a product (for example, , JAN code, etc.), number, amount, date and time when registration was performed by the registration device, receipt necessity information (eg, necessary: receipt required, no: receipt not required), and the like.

  Further, the merchandise registration apparatus 10 may designate the settlement apparatus 20. In this case, a number for guiding the settlement apparatus 20 that performs the accounting process or information for identifying the settlement apparatus 20 is printed on the settlement slip. Further, when the checkout slip is not issued, identification information such as a number for guiding the customer is displayed on the screen of the checkout device 20 that specifies the accounting process, and the clerk guides the checkout device 20 verbally. Anyway.

  Further, the CPU 101 specifies the product name, unit price, etc. of the product based on the product data read by the scanner unit 104 and the product data file (data table) stored in the hard disk 107, and displays the salesclerk display unit 105. To display.

  The salesclerk display unit 105 is, for example, a liquid crystal display device, and displays information to the operator S. Here, the information displayed by the store clerk display unit 105 includes, for example, the product name of the purchased product, the number of purchases, the selling price, and the deposit amount (custody amount) in the product registration process.

  The customer display unit 106 is, for example, a liquid crystal display device, and presents information to the customer C. For example, the customer display unit 106 displays the same information as the information displayed by the store clerk display unit 105.

  The hard disk 107 stores the product data file supplied from the store controller 30 connected via the communication unit 109. The hard disk 107 is, for example, a magnetic recording device.

  The store clerk operation unit 108 uses a numeric key for designating and inputting an amount of money, a current accounting key for designating and inputting that registration of all products purchased by the customer C is completed, and a request for issuing a checkout slip ( And a print key for notifying the CPU 101 of (issue request).

  In addition, the customer C requested that a receipt be received during registration of a product purchased by the customer C with the registration device 10 operated by the store clerk S (other than the above, it may be before registration or before closing). In this case, the store employee presses the receipt button on the customer display unit 106 on the registration device 10 side. However, a touch panel may be provided on the store clerk display unit 105 and / or the customer display unit 106, and an instruction may be given by touching the screen.

  In this case, the customer C may press the receipt button on the screen of the customer display unit 106, and the store clerk display unit 105 may display that the receipt button has been pressed. In addition, when a receipt button is provided on both the store clerk display unit 105 and the customer display unit 106, control is performed so that if one of the buttons is pressed, one of the receipt buttons cannot be pressed. Also good.

  Further, the store clerk operation unit 108 may include a product designation key set in advance for inputting product data of a specific product. As a result, for a specific product, instead of the operation of reading the product data attached to the product, the product data of the specific product is added to the transaction data by pressing the product designation key corresponding to the product. Registration process.

  The communication unit 109 is a communication interface for communicating with an external device via the LAN 40 (see FIG. 2). The communication unit 109 transmits a transaction number and transaction data to the store controller 30. The communication unit 109 may transmit transaction data including a transaction number and whether or not a receipt is issued to the store controller 30 (output unit).

  The buzzer 110 is a sound generator for generating a confirmation sound and a warning sound. The buzzer 110 generates a sound, for example, when the scanner unit 104 normally reads a barcode, when each key of the store clerk operation unit 108 is pressed, or when an incorrect operation is performed. .

  The printing unit 111 prints the barcode or two-dimensional code generated by the CPU 101 on a paper medium and discharges it (output unit).

Next, the settlement apparatus 20 will be described.
The settlement apparatus 20 reads the barcode or two-dimensional code printed on the settlement slip, or the barcode printed on the receipt, and executes payment settlement or receipt issuance.

  FIG. 4 is a block diagram showing a configuration of the settlement apparatus 20. The settlement apparatus 20 includes a CPU 201, a ROM 202, a RAM 203, a scanner unit 204, a display unit 205, a customer operation unit 206, a communication unit 207, a buzzer 208, a printing unit 209, a change machine 210, And a bus 211. These are connected to each other via a bus 211.

  The ROM 202 stores an accounting program to be executed by the CPU 101. The ROM 202 stores a device number for identifying the device itself.

  The scanner unit 204 optically reads the barcode printed on the check slip or the receipt by the operation of the customer C, and outputs the transaction number represented by the read barcode to the CPU 201. The scanner unit 204 optically reads the two-dimensional code printed on the check-out slip by the operation of the customer C, outputs the transaction data represented by the read two-dimensional code to the CPU 201, and the CPU 201 temporarily stores it in the RAM 203. (Reading means).

  The RAM 203 stores the product data file supplied from the store controller 30 via the communication unit 207. In addition, the transaction program read from the ROM 202 is expanded in the RAM 203. The RAM 203 temporarily stores various variables and data (for example, change amount) generated by executing the accounting program. The RAM 203 stores transaction data received by the communication unit 207. The RAM 203 stores transaction data represented by the two-dimensional code read by the scanner unit 204.

  The CPU 201 reads the accounting program stored in the ROM 202, expands it in the RAM 203, and executes the expanded accounting program steps to control the entire settlement apparatus 20.

  Based on the code read by the scanner unit 204, the CPU 201 determines whether the read slip is a checkout slip or a receipt for issuing a receipt. Here, whether it is a checkout slip is determined based on, for example, the contents of the code (reading means). Further, the CPU 201 determines whether or not the code read by the scanner unit 204 is a two-dimensional code. Here, whether or not the code is a two-dimensional code is determined based on, for example, whether or not the code recording method (form) is two-dimensional (reading means).

  If the code read by the scanner unit 204 is not a two-dimensional code, that is, if the code read by the scanner unit 204 is a bar code, the CPU 201 executes payment adjustment based on the bar code. Specifically, the CPU 201 inversely converts the barcode into a transaction number, and outputs the transaction number acquired by the inverse conversion to the communication unit 207. Thereby, the transaction number acquired by the reverse conversion is transmitted to the store controller 30 via the communication unit 207. In addition, the CPU 201 acquires transaction data received by the communication unit 207 from the store controller 30.

  On the other hand, when the code read by the scanner unit 204 is a two-dimensional code, the CPU 201 executes payment adjustment based on the two-dimensional code. Specifically, the CPU 201 obtains transaction data directly from the two-dimensional code by inversely converting the two-dimensional code into transaction data, and executes payment settlement based on the directly obtained transaction data.

  The CPU 201 causes the display unit 205 to display information (hereinafter referred to as “accounting menu”) including a character string and the like for prompting the customer C to proceed with the payment. In addition, based on the acquired transaction data, the CPU 201 causes the display unit 205 to display the product name, the number of purchases, the sales price, and the total price of the purchased product in the price settlement. In addition, the CPU 201 acquires the amount of cash inserted into the change machine 210 (hereinafter referred to as “payment amount”) from the change machine 210 and causes the display unit 205 to display the payment amount. Further, the CPU 201 displays a change amount in the payment.

  If the deposit amount is equal to or greater than the total amount in the price settlement, the CPU 201 ends the price settlement. Here, when the deposit amount is larger than the total amount, the CPU 201 determines that the payment has been completed after discharging the cash equivalent to the change amount from the change machine 210, and discharges the receipt from the printing unit 209. By issuing a receipt.

  Further, when the receipt is instructed by the code read by the scanner unit 204 in the payment, the CPU 201 discharges the receipt from the printing unit 209 and then discharges the receipt from the printing unit 209. At this time, the receipt issued printing is performed on the receipt (receipt issue control means).

  If the receipt is not issued, the CPU 201 prints a message indicating that the receipt cannot be used as a receipt and a barcode on the lower part of the receipt. This bar code stores information that allows the receipt device 20 to issue a receipt when it is read by the scanner unit 204 of the checkout device 20 when a receipt is desired at a later date. Further, when reading the receipt on which the barcode is printed, the CPU 201 determines whether or not the receipt has already been used for issuing the receipt from the scanned image, and is not used for issuing the receipt. If it is a receipt, a message indicating that a receipt issuance operation may be displayed.

  The CPU 201 performs image analysis on the image read by the scanner unit 204 and determines whether the receipt has already been used for issuing a receipt. In this determination method, a barcode or two-dimensional code is imaged by a CCD camera or the like, and the barcode or two-dimensional code is decoded by image analysis to obtain a transaction number (may include a receipt necessity number). Then, it is determined whether it has already been used for issuing a receipt and stored, and a receipt is issued.

  The information in the bar code is at least transaction data identification information and transaction date / time, and is stored in the settlement apparatus 20, the commodity registration apparatus 10, or the store controller (transaction data management apparatus or server apparatus) 30 based on this information. The stored transaction data (accounted data) is read out to the settlement apparatus 20 and a receipt is issued.

  The display unit 205 is a liquid crystal display device, for example, and displays information for the customer C. Here, the information displayed by the display unit 205 includes, for example, the product name of the purchased product, the number of purchases, the sales price, the deposit amount, the total amount, the change amount, and the accounting menu in the price settlement.

  The customer operation unit 206 is a touch panel type input device. The customer operation unit 206 outputs an operation signal to the CPU 201 in response to an operation on a GUI (Graphical User Interface) operation button displayed on the display unit 205. Here, as the GUI operation buttons, for example, an accounting key for causing the CPU 201 to start payment adjustment and a settlement key for causing the change machine 210 to start change processing are displayed on the display unit 205.

  The communication unit 207 is a communication interface for communicating with an external device via the LAN 40 (see FIG. 2). The communication unit 207 causes the RAM 203 to store the product data file supplied from the store controller 30 (see FIG. 2).

  In addition, when the CPU 201 determines that the code read by the scanner unit 204 is not a two-dimensional code, that is, the code read by the scanner unit 204 is a barcode, the communication unit 207 stores the transaction number represented by the barcode. It transmits to the controller 30 (refer FIG. 2). Further, the communication unit 207 receives the transaction data transmitted from the store controller 30 as the reply, outputs the received transaction data to the CPU 201, and the CPU 201 temporarily stores it in the RAM 203.

  The buzzer 208 is a sound generator for generating a confirmation sound and a warning sound. The buzzer 208 generates a sound, for example, when the scanner unit 204 normally reads a barcode, when each key of the customer operation unit 206 is pressed, or when an incorrect operation is performed. .

  When notified from the CPU 201 that the payment has been completed, the printing unit 209 prints at least one of a receipt and a receipt on a medium (for example, a paper medium) based on the transaction data stored in the RAM 203. (Printing output means).

Next, an operation procedure of the commodity registration apparatus 10 of the POS system 100 will be described.
FIG. 5 is a flowchart showing an operation procedure of the merchandise registration apparatus 10. First, the customer takes the purchased product to the product registration apparatus 10 operated by the store clerk. If the clerk receives a request from the customer for a receipt during product registration (before registration or before closing), the clerk presses the receipt button on the product registration device 10 side.

  The CPU 101 (see FIG. 3) determines whether or not a receipt issue has been instructed (step S1). If the receipt issuance is not instructed (NO in step S1), the CPU 101 executes product registration by inputting the product code (step S2). That is, the CPU 101 writes the contents in the item of transaction data stored in the processing area of the RAM 103.

  The CPU 101 determines whether or not a receipt is issued even during product registration (step S3). If the receipt issuance is not instructed (NO in step S1), it is determined whether or not the product registration has been completed for all products purchased by the customer C (step S5). For example, when the current key is pressed, the CPU 101 determines that the product registration has been completed for all products purchased by the customer C. If the product registration has not ended (NO in step S5), the CPU 101 returns the process to step S2.

  On the other hand, if receipt is instructed prior to product registration (YES in step S1), or if receipt is instructed during product registration (YES in step S3), a receipt necessity flag is set. “1” is set (step S4). The receipt necessity flag is set to “1” for receipt issuance required and “0” for no (initial value is “0”).

  On the other hand, when the product registration is completed for all products (YES in step S5), the CPU 101 additionally stores the confirmed transaction data and the receipt necessity flag in the log file of the RAM 103, and confirms the confirmed transaction data, and The receipt necessity flag is associated with the transaction number, and transmitted to the store controller 30 via the communication unit 109 (step S6). In the store controller 30, the transaction data and the receipt necessity flag are written and stored in the log file.

  Next, the CPU 101 converts the transaction number into a barcode, and issues a checkout slip on which a one-dimensional code such as a barcode representing the transaction number or a two-dimensional code obtained by converting the corresponding transaction data is printed (step). S7). More specifically, when the communication state with the store controller 30 is good, the CPU 101 converts the transaction number into a barcode and prints the barcode representing the transaction number as shown in FIG. The printed check slip is issued to the printing unit 111. Then, the CPU 101 ends the process. Note that the CPU 101 may return the process to step S1.

  On the other hand, when the communication state is negative, that is, when the communication state is not good, the CPU 101 converts the confirmed transaction data stored in the RAM 103 into a two-dimensional code, as shown in FIG. 6B. Further, a payment slip on which a two-dimensional code representing transaction data is printed is issued from the printing unit 111. Then, the CPU 101 ends the process. Note that the CPU 101 may return the process to step S1.

  FIG. 6 is a schematic diagram illustrating an example of a checkout slip issued at the time of product registration from the product registration apparatus 10. FIG. 6A shows an example of a slip on which a barcode is printed. On this slip, the transaction date and time, the transaction number, the number, the necessity of receipt, and the barcode are printed. The bar code indicates a transaction number associated with the transaction data and information on whether or not the receipt is necessary. FIG. 6B shows an example of a slip on which a two-dimensional code is printed. On this slip, a transaction date and time, a transaction number, the number, necessity of receipt, and a two-dimensional code are printed. The two-dimensional code includes transaction data and information on receipt necessity.

  The customer C (see FIG. 1) receives the issued check slip of FIG. 6 (A) or (B), and causes the checkout device 20 to read the barcode or two-dimensional code printed on the check slip. . Note that a plurality of two-dimensional codes may be printed on one checkout slip shown in FIG. 6B according to the amount of transaction data.

  The same information as the transaction data described in the receipt is displayed on the store clerk display unit 105 and the customer preparation display unit 106 (step S8). Specifically, the merchandise registration apparatus 10 transmits the transaction identification information to the store controller 30 (see FIG. 2) via the communication unit 207, and the transaction data corresponding to the transaction identification information transmitted from the store controller 30 is transmitted. It is received and displayed on the store clerk display unit 105 and the customer preparation display unit 106.

  Further, when the registration device 10 designates a specific settlement device 20, a number for guiding the settlement device 20 that performs the payment settlement or information for identifying the settlement device 20 may be printed on the settlement slip. Good.

  Further, when the checkout slip is not issued, identification information such as a number for guiding the customer is displayed on the screen of the checkout device 20 designated to perform the payment, and the clerk guides the checkout device 20 verbally. You may make it do.

  FIG. 7 is a flowchart showing an operation procedure of the settlement apparatus 20. First, the customer goes to the designated (guided) settlement apparatus 20 and instructs from the customer operation unit 206 whether to perform accounting processing according to the settlement slip or to issue a receipt according to the previously issued receipt. Or, it is instructed by a touch operation from the touch panel type display unit 205. Alternatively, the customer can read the code information of the check slip or the receipt by the scanner unit 204 provided in the checkout device 20, so that the account processing is performed from the code information read by the checkout device 20, or the receipt is issued. You may make it determine.

  In the code information, if it is a one-dimensional code (bird code), information on whether or not a receipt is issued is stored in the transaction data, and if it is a two-dimensional code, information on whether or not a receipt is issued is stored in itself. Since it is included, it is possible to determine whether it is an accounting process or a receipt issuance. In addition, when transaction data is transmitted to the settlement apparatus 20 and the settlement slip is not issued, when the customer approaches, the accounting screen is displayed or when the customer touches a button on the screen, the accounting screen is displayed. Use a display method.

  In the settlement apparatus 20, the CPU 201 determines whether or not it is an accounting process (step S20). If it is an accounting process (YES in step S20), first, whether the read code information is a two-dimensional code. It is determined whether or not (step S21). When the code read by the scanner unit 204 is a two-dimensional code (YES in step S21), the CPU 201 shifts the process to step S24.

  On the other hand, when the code read by the scanner unit 204 is not a two-dimensional code (NO in step S21), the CPU 201 reversely converts the barcode read by the scanner unit 204 into a transaction number, and the transaction number obtained by the reverse conversion. Is transmitted to the store controller 30 via the communication unit 207 (step S22). Thereafter, when receiving transaction data within a predetermined time (step S23), the CPU 201 displays the total amount on the display unit 205 (step S24).

  Next, the CPU 201 displays a screen for selecting an accounting method (for example, cash, credit card, electronic money, etc.) on the display unit 205, and allows the customer to select an accounting method (step S25). Then, according to the selected accounting method, the CPU 201 displays the next operation screen and executes a payment process (step S26). Specifically, the CPU 201 causes the display unit 205 to display the product name, the number of purchases, the sales price, and the total amount of purchased products based on the acquired transaction data. In addition, the CPU 201 acquires the deposit amount from the change machine 210 and causes the display unit 205 to display the deposit amount. Further, when the deposit amount is larger than the total amount, the CPU 201 displays the change amount on the display unit 205 and discharges the cash equivalent to the change amount from the change machine 210.

  Next, when the payment is completed, the CPU 201 determines whether or not a receipt necessity flag is “1”, that is, whether or not a receipt is issued (step S27). When the receipt necessity flag is “1”, that is, when a receipt is issued (YES in Step 27), the date and time, the transaction number, the purchased product, the number, the unit price, the total amount, the deposit amount, etc. 8 is discharged from the printing unit 209, and a receipt as shown in FIG. 8A is issued (step S28). Next, the CPU 201 discharges the paper medium on which the date and time, the transaction number, the purchased product, the number, the unit price, the total amount, and the like are printed from the printing unit 209, so that the receipt as shown in FIG. Is issued (step S29). And CPU201 memorize | stores that the receipt has been issued to transaction data (transaction data is transmitted to the store controller 30 via the communication part 207), and complete | finishes the said process (or even if it returns to step S20) Good).

  FIG. 8A shows an example of a receipt when issuing a receipt. On the receipt, the name of the person in charge, the transaction date and time, the transaction number, the product name, the number of purchases of the product, the amount, the total amount, the deposit amount, and the store name are printed. In this case, since the receipt shown in FIG. 8B is issued, “receipt issued” is printed on the receipt as shown in FIG. 8A.

  On the other hand, when the receipt necessity flag is “0”, that is, when the receipt is not issued (NO in step S27), the date and time, the transaction number, the purchased item, the number, the unit price, the total amount, the deposit amount, etc. Is discharged from the printing unit 209, thereby issuing a receipt as shown in FIG. 9 (step S30).

  FIG. 9 shows an example of a receipt when no receipt is issued. As in FIG. 8A, the receipt includes the name of the person in charge, the transaction date and time, the transaction number, the product name, the number of purchases of the product, the amount, the total amount, the deposit amount, and the store. If the name is printed and a receipt is requested at a later date, information (transaction number) that can be issued by the checkout device 20 is stored when the scanner unit 204 of the checkout device 20 reads the receipt. The barcode is printed.

  On the other hand, if it is not an accounting process (NO in step S20), the CPU 201 determines that the process is a process of issuing a receipt by reading a barcode of a previously issued receipt, and displays a receipt bar on the display unit 205. An instruction to read the code is displayed, and it is determined whether or not the bar code has been read (step S31). When the barcode on the receipt is read (YES in step S31), the CPU 201 analyzes the image on the receipt using the scanner (step S32) to determine whether it is a previously read receipt barcode (step S32). It is determined whether or not the receipt has been issued (step S33).

  Here, the image analysis will be described. Receipts may be used as receipts by themselves, so when issuing a receipt, the receipt will be received when issuing a receipt to prevent the receipt from being used as a receipt. A print is made to indicate that the receipt has been issued, and if the receipt is not issued, it is printed on the receipt that it cannot be used as a receipt. In this embodiment, since the receipt is issued by the checkout device 20 operated by the customer, when the receipt is issued, the receipt is printed indicating that the receipt has been issued, but the receipt is issued at a later date. In order to do so, a barcode is printed on the receipt to issue a receipt at a later date.

  The barcode includes code information (transaction number, etc.) that makes the receipt unique in addition to receipt necessity information. This code information is decoded by image analysis and used (already issued a receipt). It is determined whether the receipt is already completed. As a result, code information (transaction number, etc.) that uniquely identifies a receipt once used is stored in advance, so it can be determined whether or not a receipt has been issued. Since the fact that it cannot be used as a receipt is printed in advance, the receipt itself cannot be used as a receipt.

  If the code information (transaction number, etc.) that makes the receipt unique is stored in advance as a receipt issued (NO in step S33) as a result of decoding the code information by scanning image analysis, An error is displayed to the clerk (step S34). Then, the CPU 201 ends the process. Note that the CPU 101 may return the process to step S20.

  On the other hand, if the code information (transaction number, etc.) that makes the receipt unique is not stored in advance as a receipt issued (YES in step S33), the CPU 201 acquires it from the barcode read by the scanner unit 204. The transaction number is transmitted to the store controller 30 via the communication unit 207 (step S32). Thereafter, when receiving transaction data from the store controller 30 within a predetermined time (step S33), the CPU 201 determines whether or not a receipt has already been issued in the transaction for the receipt (step S37).

  If a receipt has already been issued (YES in step S37), an error display indicating that a receipt has already been issued is displayed (step S34). Then, the CPU 201 ends the process (or may return to step S20). On the other hand, if a receipt has not been issued (NO in step S37), a paper medium on which the date / time, transaction number, purchased product, number, unit price, total amount, etc. are printed is ejected from the printing unit 209. Then, a receipt as shown in FIG. 8B is issued (step S38). Then, the CPU 201 stores in the transaction data that a receipt has been issued (transaction data is transmitted to the store controller 30 via the communication unit 207), and the processing ends. Note that the CPU 101 may return the process to step S20.

  As described above, in the POS system 100 having the registration device 10 for registering the product purchased by the customer and the settlement device 20 for executing the settlement process based on the transaction details of the product registered by the registration device 10, The POS system 100 includes a CPU 101 for setting receipt necessity information indicating whether or not a receipt for a product purchased by the customer is issued, and a printing unit 111 for outputting information including the receipt necessity information. A registration device 10 having: a reading unit that reads out receipt necessity information output by the printing unit 111; and a CPU 201 that controls issuance of a receipt based on the receipt necessity information read out by the reading unit. A settlement apparatus 20.

  With this configuration, the printing unit 111 outputs information including receipt necessary / unnecessary information indicating whether or not a receipt for a product purchased by the customer is issued. The CPU 201 controls the receipt issuance based on the output receipt necessity information. Thereby, the POS system can issue a receipt without going through the store clerk. In addition, the POS system can improve customer satisfaction. The POS system also prevents the store clerk from being called inadvertently and prevents customers from waiting until the store clerk arrives.

  In addition, the POS system includes a printing unit 209 that outputs code information that permits issuance of a receipt for a transaction of a product purchased by a customer to a medium so that the checkout device 20 is read by the reading unit. If the receipt necessity information is essential, issue a receipt indicating that the receipt of the transaction for which the payment has been settled has been issued, and a receipt for the transaction for which the payment has been settled. If the read receipt necessity information is NO, the printing unit 209 prints code information that permits printing and receipt issuance indicating that the receipt cannot be used as a receipt for the transaction for which the payment has been settled. , Output to receipt so that it can be read.

  In the POS system, the reading unit reads code information that permits the issuance of the receipt from the medium output by the printing unit 209, and the printing unit 209 reads the code information read by the reading unit. Based on this, a receipt indicating that the receipt of the transaction for which the price has been settled has been issued and a receipt for the transaction for which the price has been settled are output.
