The POS terminal 1 includes a CPU 100 functioning as a control center, a ROM 101, a RAM 102, a communication I / F 103, a scanner I / F 104, display controllers 105 and 106, a keyboard controller connected to the CPU 100 via a bus line 110. 107, a card reader controller 108, a printer controller 109, a barcode scanner 111 connected to the scanner I / F 104, a store clerk display 112 (display means) and a touch panel 113 connected to the display controller 105, and the above A customer display 114 connected to the display controller 106, a keyboard 115 connected to the keyboard controller 107, and the card reader controller 108 A card reader 116 that is continued, and a receipt printer 117 connected to the printer controller 109.

  The ROM 101 stores fixed data such as a control program for the POS terminal 1. The RAM 102 functions as a main memory of the POS terminal 1 and temporarily stores various data. The communication I / F 103 is connected to a LAN (Local Area Network) of the store where the POS terminal 1 is installed, and a LAN line 130 for communication connection of the POS terminal 1 is connected. Controls data communication with external devices.

  The barcode scanner 111 is, for example, a hand-held scanner that is operated by an operator, and optically reads a barcode attached to a product and decodes it into a product code. The scanner I / F 104 takes in the product code decoded by the barcode scanner 111 and notifies the CPU 100 of it.

  The store clerk display 112 is, for example, an LCD (Liquid Crystal Display), and displays a product registration screen 200 (see FIGS. 3 and 5), a payment screen 300 (see FIG. 8), and various setting screens. The touch panel 113 is provided on the display surface of the store clerk display 112 and outputs a signal corresponding to a position touched by an operator's finger or a touch pen. The display controller 105 controls the screen display of the store clerk display 112 in accordance with a command from the CPU 100, and monitors the operation of the GUI displayed on the store clerk display 112 based on a signal output from the touch panel 113. If such GUI is operated, the CPU 100 is notified of this fact.

The customer display 114 is, for example, a VFD (Vacuum Fluorescent Display), and selectively displays the name and price of products registered for sale, the total amount of transactions, the amount of change, and the like. The display controller 106 controls the screen display of the customer display 114 in response to a command from the CPU 100. The keyboard 115 includes a PLU (Price Look Up) key, a deposit / cash key, a cancel key, and a numeric key. A mechanical keyboard that outputs a signal corresponding to the depressed operation key. The keyboard controller 107 captures a signal output from the keyboard 115 and notifies the CPU 100 of it.

  The card reader 116 is an IC type or magnetic type card reader that reads card information from a credit card, a David card, a point card of the store, or the like. The card reader controller 108 captures card information read by the card reader 116 and notifies the CPU 100 of it.

  The receipt printer 117 issues a receipt on which transaction details and the like are printed. The printer controller 109 drives the receipt printer 117 in response to a command from the CPU 100 and issues the receipt.

[Memory configuration]
FIG. 2 is a memory configuration diagram of the RAM 102. The RAM 102 stores a product master 120 and a sales promotion information file 121 distributed from the store server, and flags F1 and F2 and a sales registration buffer 122 are formed during product registration processing.

  The product master 120 is composed of records provided for each product sold in the store, and each record describes a product code, a product name, a unit price, and the like of the corresponding product. For example, in the illustrated record of the product code “C001”, the product name “Tamago L Pack”, the unit price “¥ 198”, and the like are described.

  The sales promotion information file 121 is a file showing the reduction condition and the discount amount. In the example shown in the figure, the reference amount “¥ 1000” and the product code “C001” of the promotion target product are described as the reduction condition, and the discount amount is “¥ 98”. Is described. This is a case where the total price of products other than sales promotion registered products exceeds the standard amount “¥ 1000”, and the products registered for sale include the products with the product code “C001”, that is, “Tamago L Pack” This means that the product is discounted by the discount amount “¥ 98”.

  Either “0” or “1” is set in the flags F1 and F2. Specific roles of the flags F1 and F2 will be described later in the description of FIGS.

  The sales registration buffer 122 is an area for storing the product data of the product for which the product code is input by the barcode scanner 111 or the like, and the product code, product name, purchased quantity, unit price, value discount from the unit price, and It consists of a record consisting of the sales amount obtained by multiplying the amount obtained by subtracting the value discount amount from the unit price by the quantity. Each record may be provided blank from the beginning of the product registration process, or may be formed each time product data is registered.

  Next, the operation of the POS terminal 1 will be described.

[Product registration process]
When the POS terminal 1 is set to the accounting operation mode by operating a mode switch (not shown), a product registration screen 200 as shown in FIG. This screen 200 has a current area 201 and a registration details area 202 for displaying each product data in the sales registration buffer 122, a total area 203, and a subtotal button 204 (subtotal instruction means). The current area 201 displays the product name, quantity, and sales price of the most recently registered product, and the registration details area 202 displays the product name and quantity of the product registered before the product displayed in the current area 201. Unit price, value discount amount (“value discount” in the figure), sales amount (“money amount” in the figure), etc. are displayed in the order of sales registration with an ascending number from “1”. The total area 203 displays the total score and total amount of products registered for sale. The subtotal button 204 is used to input a subtotal instruction for the selling price of a product registered for sale, and is a GUI that can be operated by touching the display position. Although the example shown in the figure shows a state in which some products have already been registered for sale, at the beginning of the product registration process, the current area 201, the registration details area 202, and the total area 203 have product data and total points, The total amount is not displayed.

  When the PLU key of the keyboard 115 is operated while the product registration screen 200 is displayed, the CPU 100 executes the control program stored in the ROM 101 and starts the product registration process. A flowchart of this process is shown in FIG.

  At the beginning of the product registration process, the CPU 100 executes an initialization process for the flags F1 and F2 and the sales registration buffer 122 (step S101). Through this initialization process, the flags F1 and F2 are reset to “0” and the data in the sales registration buffer 122 is cleared.

  Next, the CPU 100 reads a barcode by the barcode scanner 111, inputs a product code by operating a preset key displayed on the store clerk display 112, and inputs various instructions by operating the store clerk display 112 or the keyboard 115. Accept (step S102). When there is any input, the CPU 100 determines the type of the input (step S103).

  When the input type is input of a product code (“product code” in step S103), the CPU 100 registers and sells a product corresponding to the input product code (step S104). Specifically, the product name and unit price corresponding to the input product code are read from the product master 120 and described in an empty record in the sales registration buffer 122. At this time, if the quantity is not specified, the quantity of the record is set to “1”, and if the quantity is specified, the quantity of the record is set to the specified number. Also, the value discount amount of the record is “0”, and the sales amount is calculated and described in the record.

  After selling and registering the product in this way, the CPU 100 displays the product name, quantity, and unit price of the record corresponding to the product in the sales registration buffer 122 in the current area 201, and the quantity and each record in the sales registration buffer 122. Based on the sales amount, the total score and the total amount are calculated and displayed in the total area 203 (step S105). If a product name or the like is displayed in the current area 201 at the time of sales registration of the product, the data in the sales registration buffer 122 corresponding to the product name is displayed at the end (lowermost) of the registration details area 202.

  Next, the CPU 100 determines whether or not the product designated as the sales promotion target in the sales promotion information file 121 is registered for sale (step S106). If there is no record having the sales promotion target product code “C001” in the sales registration buffer 122, it is determined that the sales promotion target product is not registered for sales (No in step S106), and the process returns to step S102. Repeat the process.

  On the other hand, when the record having the product code “C001” is in the sales registration buffer 122, it is determined that the sales promotion target product is registered for sale (Yes in step S106), and the CPU 100 determines the record of each record in the sales registration buffer 122. Based on the sales amount, the total amount excluding the sales amount of the sales promotion target product is calculated (step S107: calculation means). Then, the CPU 100 determines whether or not the calculated total amount is equal to or larger than the reference amount “¥ 1000” of the sales promotion information file 121 (step S108). As a result, when the total amount is less than the reference amount (No in step S108), the CPU 100 returns to the process in step S102 and repeats the subsequent processes.

On the other hand, when the total amount is equal to or greater than the reference amount (Yes in step S108), the CPU 100 executes a reduction process for the sales promotion target product (step S109). In this process, the discount amount “¥ 98” of the sales promotion information file 121 is described in the value discount amount of the record corresponding to the sales promotion target product in the sales registration buffer 122, and the sales amount of the record is recalculated. In this way, the selling price of the sales promotion target product is reduced.
In addition, the process of step S106, S108, S109 comprises the reduction means in this embodiment.

  After the reduction process, the CPU 100 changes the display order of the product data so that the product data of the sales promotion target product is located at the end of the registration details area 202 (step S110: display position changing unit). For example, from the state where the product is registered for sale as shown in FIG. 3, “Green tea” is registered for sale as shown in FIG. 5, and the total amount excluding “Tamago L Pack” which is the promotion target product is the reference amount “¥ 1000”. The product data of the “tamago L pack” originally displayed at the position of the number “1” is moved to the position of the number “6” at the end, and the other product data is added up. Further, the value discount amount of “Tamago L Pack” is set to “− ¥ 98”, and the sales amount is set to “¥ 100”. After such processing, the CPU 100 sets the flag F1 to “1” (step S111), returns to the processing of step S102, and repeats the subsequent processing.

[Cancel processing]
When the input accepted in step S102 of the merchandise registration process is an input of a cancel instruction by operating the cancel key of the keyboard 115 (“cancel instruction” in step S103), the CPU 100 executes a cancel process (step S112). A flowchart of this process is shown in FIG.

  At the beginning of the cancellation process, the CPU 100 accepts designation of a product to be canceled (step S201: product designation means). When a product to be canceled is specified by a touch operation on the clerk display 112 or a keyboard 115 operation, the CPU 100 determines whether or not the flag F1 is set to “1” (step S202). When the flag F1 is set to “1” (Yes in step S202), the reduction process in step S109 is performed. In this case, the CPU 100 determines whether or not the reduction condition of the sales promotion information file 121 is satisfied even after canceling the sales registration of the designated cancellation target product (step S203). At this time, if the total amount of the product excluding the promotion target product is less than the standard amount after the cancellation, or if the promotion target product itself is designated as the cancellation target, it is determined that the reduction condition is not satisfied after the cancellation. (No in step S203), the CPU 100 notifies that the reduction will disappear due to the cancellation (step S204). This notification is performed, for example, by displaying a message to the effect that the reduction will disappear on the store clerk display 112 and the customer display 114. Further, the CPU 100 displays an execution button for permitting execution of cancellation and a cancel button for canceling cancellation on the store clerk display 112, and confirms whether or not cancellation execution is permitted (step S205: confirmation means).

  When the operator performs a touch operation on the cancel button, the CPU 100 determines that the cancellation has been cancelled (“Cancel” in step S205), returns to the process in step S102, and repeats the subsequent processes. On the other hand, when the operator touches the execution button, the CPU 100 determines that execution of cancellation is permitted ("execute" in step S205), sets the flag F1 to "0" (step S206), and designates The canceled record of the merchandise to be canceled is deleted from the sales registration buffer 122 to confirm the cancellation (step S207: canceling means). Then, the product data of the product to be canceled is deleted from the registration details area 202, and other product data is added up, and the total score and the total amount are recalculated and displayed in the total area 203 (step S208). Thereafter, the process returns to step S102 and the subsequent processes are repeated.

  When it is determined that the flag F1 is not set to “1” in the process of step S202 (No in step S202), and when it is determined that the reduction condition is satisfied even after cancellation in the process of step S203 (in step S203). Yes) After executing the processes of steps S207 and S208, the CPU 100 returns to the process of step S102 and repeats the subsequent processes.

[Checkout]
When the input accepted in step S102 of the product registration process is an input of a subtotal instruction by operating the subtotal button 204 (“subtotal instruction” in step S103), the CPU 100 executes a settlement process (step S113). . A flowchart of this process is shown in FIG.

  At the beginning of the checkout process, the CPU 100 displays a payment screen 300 as shown in FIG. 8 on the clerk display 112 (step S301). This screen 300 is displayed when the subtotal button 204 is touch-operated from the state of the product registration screen 200 shown in FIG. 5, and is a total area for displaying the total score and subtotal amount of products registered for sale. 301, a message 302 for prompting a payment operation and a subtotal discount operation, a subtotal discount button 303 for instructing execution of a subtotal discount, a subtotal discount button 304 for instructing execution of a subtotal discount, and an instruction for selecting a payment method A payment method selection button 305 and a registration details button 306 for instructing redisplay of the product registration screen 200 are provided. The buttons 303 to 306 are GUIs that can be operated by touching the display position.

  After displaying such a payment screen 300, the CPU 100 determines whether or not the flag F1 is set to “1” (step S302). When the flag F1 is set to “1” (Yes in step S302), the reduction process in step S109 is performed. In this case, the CPU 100 notifies that the sales promotion target product has been reduced (step S303: reduction notification means), and sets the flag F2 to “1” indicating that the reduction notification has been made (step S304). The notification in step S303 is performed by displaying a pop-up 400 as shown in FIG. The pop-up 400 includes a message 401 indicating that the sales promotion target product indicated by the sales promotion information file 121 has been reduced by the discount amount indicated by the file 121, and a close button 402 for closing the pop-up 400. The close button 402 is a GUI that can be operated by touching the display position.

  When the close button 402 is touched, the CPU 100 closes the pop-up 400 and accepts operations for the buttons 303 to 306 on the payment screen 300 (step S305). When any button is touched, the CPU 100 determines the type of the operated button (step S306). When the operated button is the payment method selection button 305 (“payment method selection button” in step S306), the CPU 100 selects, for example, cash payment, credit card payment, or electronic money payment on the store clerk display 112. GUI for displaying is displayed, and selection of a payment method for the price is accepted (step S307). And the payment process by the received payment method is performed (step S308). For example, if cash payment is selected, the input of the deposit amount is accepted, and the change is calculated by subtracting the subtotal amount of the total area 301 from the input amount, and is displayed on the store clerk display 112 or the customer display 114. If credit card payment is selected, the card reader 116 accepts the reading of the credit card, and accesses the card company management server based on the read card information to make a card payment. If electronic money payment is selected, the subtotal of the total area 301 is deducted from an electronic money medium placed on an electronic money interface (not shown). When the payment process is completed by any of the methods, the CPU 100 causes the receipt printer 117 to issue a receipt or a credit slip on which the detailed information of the transaction is printed (step S309), and ends the settlement process.

  On the other hand, when the operation received in the process of step S305 is an operation of the subtotal discount button 303 or the subtotal discount button 304 (“discount button, discount button” in step S306), the CPU 100 performs the value discount process for the subtotal amount. Execute (Step S310). In this process, for example, when the subtotal discount button 303 is operated, the input of the discount amount by the operation of the keyboard 115 is accepted, and the sum of the total area 301 is obtained by subtracting the discount amount from the current subtotal amount. Update the subtotal amount. When the subtotal discount button 304 is operated, the input of the discount rate by operating the keyboard 115 is accepted, and the subtotal amount in the total area 301 is updated with an amount obtained by subtracting the current subtotal amount according to the discount rate. To do. After executing the value discount process for the subtotal in this way, the CPU 100 returns to the process of step S305 and executes the subsequent processes.

  On the other hand, when the operation accepted in the process of step S305 is an operation of the registration details button 306 (“registration details button” in step S306), the CPU 100 deletes the payment screen 300 from the store clerk display 112 and the product registration screen 200. Is displayed (step S311), the process returns to the process of step S102 in the product registration process, and the subsequent processes are executed.

  When the flag F1 is not set to “1” in the process of step S302 (No in step S302), the CPU 100 determines whether or not the flag F2 is set to “1” (step S312). After the reduction of the sales promotion target product is notified by the pop-up 400 (step S303), the registration details button 306 is operated to redisplay the product registration screen 200 (step S311), and the subtotal button 204 is operated again to pay the payment screen 300. Is displayed (step S301), and the flag F1 is set to “0” because the reduction condition is not satisfied by the cancellation process (step S206), the flag F1 is “0” and the flag F2 is “ 1 "(No in step S302, Yes in S312). In this case, the CPU 100 notifies the decrease disappearance (step S313: disappearance notification means) and sets the flag F2 to “0” (step S314). The notification in step S313 is performed, for example, by displaying a pop-up 500 as shown in FIG. This pop-up 500 is displayed when “Tomato” is canceled from the state where the product is registered for sale as shown in FIG. 5 and the reduction disappears, and the reduction shown in the promotional information file 121 has disappeared. And a close button 502 for closing the pop-up 500. The close button 502 is a GUI that can be operated by touching the display position. When the close button 502 is touched, the CPU 100 closes the pop-up 500, accepts operations for the buttons 303 to 306 on the payment screen 300 (step S305), and executes the subsequent processing. This is the end of the series of descriptions regarding the operation of the POS terminal 1.

  As described above, when the POS terminal 1 according to the present embodiment executes the reduction process in response to the total price of the products registered for sale exceeding the reference amount (step S109), the product data of the sales promotion target product is stored. The display order of each product data in the registration details area 202 is changed so as to be positioned at the end (step S110). Therefore, the operator can know that the sales promotion target product has been reduced only by looking at the product registration screen 200 even during product registration.

  Further, when the subtotal instruction is input in a state where the sales promotion target product is reduced, the POS terminal 1 notifies the reduction by the pop-up 400 (step S303). Therefore, even when the operator does not notice that the display order of each product data in the registration details area 202 has been changed, the operator can be sure that the sales promotion target product has been reduced at the time of subtotal instruction.

  Further, the POS terminal 1 notifies the reduction of the sales promotion target product by the pop-up 400 (step S303), and then cancels the sales registration of the product by the cancellation process (step S112). The reduction disappearance is notified (step S313). Therefore, the operator can surely know not only the reduction but also the disappearance of the reduction.

  In addition, when the cancellation target product is designated in the cancellation process after reducing the sales promotion target product (step S201), the POS terminal 1 notifies the fact that the reduction disappears due to the cancellation of the product ( In step S204, the operator confirms whether or not cancellation is permitted (step S205). In such a configuration, the operator can tell the customer that the reduction will be lost by canceling the product, stop the cancellation of the product, or encourage the purchase of a product that replaces the product. can do.
