  An operation example of the POS terminal performed by the operator will be described. First, the case where only one product with the same product code is stored in the shopping cart brought to the counter table by the customer will be described. In this case, for the product, only the operation for causing the barcode scanner to read the product code is performed, and the numeric keypad is not pressed.

  On the other hand, when two or more products with the same product code are stored in the shopping cart, in addition to the operation of causing the barcode scanner to read the product code, the operation of pressing the numeric keypad to input the quantity Necessary. For example, if the same product is stored in the shopping basket, the operator, as one procedure, presses the numeric keypad in the order of “3” and “x”, and then causes the barcode scanner to read the product code. Input to the POS terminal. In this case, a series of inputs “3”, “×”, and “product code” are confirmed upon input of the product code, and information that the product quantity = 3 is displayed on a display device or the like provided in the POS terminal. .

  By the way, for example, when trying to input in the order of “3”, “×”, and “product code”, the user may accidentally forget to press the key for inputting the multiplication operator “×”. In this case, a series of inputs “3”, “×”, and “product code” is not confirmed, and the operator forgets to input “x” for the first time because the information “product quantity = 3” is not displayed on the display device. I notice it. At this time, if an input mistake can be noticed as soon as possible in the middle of input, the transaction can be performed quickly.

  Patent Document 1 is a document found by a patent search conducted from the viewpoint of an input error in a merchandise sales data processing apparatus. However, the technique described in Patent Document 1 displays the quantity (score) of the input merchandise so that it can be confirmed. Therefore, it is not intended to make it possible to quickly find an input error in the input process.

  An object of the present invention is to enable an operator who operates a merchandise sales data processing apparatus such as a POS terminal to quickly find an input error.

  The merchandise sales data processing apparatus of the present invention includes an information processing unit that executes information processing, a display unit that displays information, and an input unit that inputs information, and the information processing unit is input by the input unit. The display unit displays a screen having a main area that displays numbers and operators in the order of input and a sub-area associated with the main area, and the display unit displays the screen. In the state where the number is input next to the operator by the input unit, the number and the operator displayed in the main area are moved from the main area to the sub area and displayed. When no number is input after the operator by the input unit, the number and operator displayed in the main area are transferred from the main area to the sub area. It performs a process not move display.

  A program for a merchandise sales data processing apparatus according to the present invention is a computer program of a merchandise sales data processing apparatus comprising a display unit for displaying information and an input unit for inputting information. A function of displaying a screen having a main area for displaying children in an input order and a sub-area associated with the main area on the display unit, and the screen being displayed on the display unit, When a number is input next to an operator by the input unit, the number and operator displayed in the main area are moved from the main area to the sub-area and displayed, while being calculated by the input unit. If no number is input next to the child, the number and operator displayed in the main area are moved from the main area to the sub area. A function to process not to indicate, to the execution.

  According to the present invention, numbers and operators (such as “x”) are displayed in the order of input. When a number is input after the operator is input, the number and operator displayed in the main area are moved to the sub area and the newly input number is displayed in the main area. Thereby, the operator can confirm the input process. In addition, since the display is not moved when the operator forgets to input, it is particularly easy to notice an operator input mistake. In this way, the operator can quickly find an input error.

  FIG. 2 is a block diagram showing the hardware configuration of the POS terminal 11 and the barcode scanner 101. The POS terminal 11 includes a microcomputer (hereinafter referred to as a microcomputer) 60 as an information processing unit that executes information processing. The microcomputer 60 includes a CPU 61 that executes various arithmetic processes and controls each unit, a ROM 62 that stores and saves fixed data such as programs in a fixed manner, and a RAM 63 that stores variable data in a rewritable manner and is used as a work area. It is configured with a bus connection.

  The drawer 61, the keyboard 22, the display device 23, the touch panel 26, and the customer display device 24 are all connected to the CPU 61 of the POS terminal 11 through various input / output circuits (all not shown). . These are controlled by the CPU 61.

  The keyboard 22 has a numeric key 22a as an input unit on which numbers such as “1”, “2”, “3”... Are displayed on the upper surface, and a multiplication operator “×” (hereinafter referred to as a multiplication operator). ) Includes a multiplication key 22b as an input unit displayed on the upper surface.

The touch panel 105 may be touch-designated.

  An HDD 64 is connected to the CPU 61 of the POS terminal 11. The HDD 64 stores programs and various files. All or a part of the programs and various files stored in the HDD 64 are copied to the RAM 63 and used when the POS terminal 11 is activated. An example of a program stored in the HDD 64 is a product sales data processing program (not shown). An example of a file stored in the HDD 64 is a product master file MMF distributed and stored from the store computer SC.

  FIG. 3 is a schematic diagram showing a data structure of the product master file MMF. The product master file MMF is a file that stores product information of a product specified by the product code in association with the “product code”. The “product code” is a JAN code that is a 13-digit number or an in-store code that is a 26-digit number. The product information includes “attribute”, “product name”, “unit price”, “value discount”, and “tax” for the product specified by the product code. “Attribute” is a product attribute of the product. For example, if the product is a product that is prohibited from being sold to minors, an attribute of “20 prohibited” is stored. “Product name” is the name of the product. For example, product names such as “Sawayaka Kogen Milk” and “Tomato” are stored. “Unit price” is the unit price of the product. For example, numbers such as “180” and “150” are stored. The “value discount” is information on discount discount for the corresponding “unit price”. For example, when “10% discount” is stored as “value discount” corresponding to “unit price” which is “150 (yen)”, the actual unit price is 135 yen. “Tax” is information about whether or not the corresponding “unit price” is a domestic tax. If it is a domestic tax, “inside” is stored. In this case, the “unit price” is an amount including consumption tax.

  Returning to the description based on FIG. A communication interface 25 for performing data communication with the store computer SC is connected to the CPU 61 of the POS terminal 11 via an input / output circuit (not shown). The store computer SC is installed in a store backyard or the like. A product master file MMF distributed to the POS terminal 11 is stored in an HDD (not shown) of the store computer SC.

  The CPU 61 of the POS terminal 11 is connected to a connection interface 65 that enables data transmission / reception with the barcode scanner 101. Therefore, the connection interface 65 is connected to the barcode scanner 101.

  The barcode scanner 101 also includes a microcomputer 160 as an information processing unit that executes information processing. The microcomputer 160 is configured by connecting a ROM 162 and a RAM 163 to the CPU 161 via a bus. The ROM 162 stores a program executed by the CPU 161. The operation unit 104 and the scanner unit 164 are connected to the CPU 161 via various input / output circuits (none of which are shown). These operations are controlled by the CPU 161. The scanner unit 164 includes an LED control unit that controls the operation of the LED, an A / D conversion unit to which a CCD sensor is connected, and a decoding unit (all not shown). The A / D conversion unit converts the electrical signal received from the CCD sensor into a digital signal by an amplifier circuit and a digital conversion circuit. The decoding unit decodes the converted digital signal into a product code and outputs the product code. Furthermore, a connection interface 175 that connects to the connection interface 65 of the POS terminal 11 and enables data transmission / reception with the POS terminal 11 is connected to the CPU 161.

  The product code read (decoded) by the scanner unit 164 of the barcode scanner 101 is output via the connection interface 175 by the CPU 161 and input to the POS terminal 11 via the connection interface 65.

  When the CPU 61 of the POS terminal 11 determines the input of the product code, it executes product sales data processing based on the input determined product code in accordance with the program stored in the ROM 62. That is, the CPU 61 of the POS terminal 11 searches the product master file MMF using the input determined product code as a key, and stores the corresponding product information (product name, unit price,...) Data in the RAM 63. And the process which calculates the total amount based on the unit price memorize | stored in RAM63 is performed. During the execution of the merchandise sales data process, the CPU 61 of the POS terminal 11 controls the display device 23 to display the detail screen AG on the display surface 23a. The detail screen AG displays the product information stored in the RAM 63 during the execution of the product sales data processing.

  FIG. 4 is a schematic diagram showing a detail screen AG. The detail screen AG is composed of a plurality of areas. That is, the detail screen AG has a header area AG1, a detail area AG2, a current area AG3, and a footer area AG4 in order from the top.

  A character string “registration details” is displayed at the center position of the header area AG1. In the header area AG1, a date and time display AG11 indicating the current date and time is displayed on the left end, and a registration number display AG12 for identifying the POS terminal 11 is displayed on the right end. An operator name display area AG13 for displaying the name of the operator who is signed on to the POS terminal 11 is provided below the cash register number display AG12.

  In the detail area AG2, the product information stored in the RAM 63 during the execution of the product sales data processing is displayed for each line. Therefore, the item “attribute”, “product name”, “unit price”, “value discount”, and “tax” are provided in the detail area AG2 so as to correspond to the data items of the product master file MMF. It has been. In addition, in the detail area AG2, “No.”, which is a number assigned with a serial number, “Quantity”, which is the quantity of a product that is input as will be described later, and “Value discount” are reflected. There is also an item. FIG. 4 illustrates a detail area AG2 when “quantity” is “1” and product codes “XXX wine” and “tomato” are input in that order.

  The current area AG3 includes a product name display area AG31, a quantity display area AG32, an amount display area AG33, and a total quantity total amount display area AG34. The current area AG3 will be described later.

  A plurality of keys are displayed in the footer area AG4. When these keys are touch-designated by the touch panel 26, the CPU 61 of the POS terminal 11 executes a function assigned to the keys. In the following description, “the key displayed on the display surface 23a is touch-designated by the touch panel 26” may be simply referred to as “the key is pressed”.

  Next, processing when a number is input while such a detail screen AG is displayed will be described with reference to FIG. The process described based on FIG. 5 is a process executed by the CPU 61 of the POS terminal 11 according to a program stored in the ROM 62.

  FIG. 5 is a flowchart showing the flow of processing executed by the POS terminal 11. When the operator operating the POS terminal 11 presses the numeric keypad (numeric key 22a or multiplication key 22b), the CPU 61 of the POS terminal 11 determines whether the numeric keypad is pressed (Y in step S101). The CPU 61 of the POS terminal 11 controls the display device 23 to display the pop-up screen PU (see FIG. 6) in a pop-up on the display surface 23a in response to the determination of pressing the numeric keypad (step S102).

  FIG. 6 is a schematic diagram showing a state in which the pop-up screen PU is displayed on the detail screen AG. The pop-up screen PU is pop-up displayed at a position straddling the detail area AG2 and the current area AG3 of the detail screen AG. Therefore, part of the detail area AG2 and the current area AG3 is hidden by the pop-up screen PU. The pop-up screen PU has a two-stage configuration. That is, the pop-up screen PU has a main area PU1 that is positioned in the lower part and displays symbols such as numbers and multiplication operators, and a sub-area PU2 that is positioned in the upper part. The main area PU1 is thicker in the vertical direction than the sub area PU2. In the sub area PU2, a character string “numerical value input” is displayed at the center position. However, as will be described later, symbols such as numbers and multiplication operators are also displayed in the sub-area PU2. In this case, the character string “Numerical value input” is deleted (see FIG. 7F).

  Returning to the description based on FIG. By pressing the numeric key 22a, which is the numeric keypad in step S101, the number displayed on the pressed numeric key 22a is input. In addition, the multiplication operator “×” is input by depressing the multiplication key 22b which is the numeric keypad in step S101. When the CPU 61 of the POS terminal 11 determines input of a number or multiplication operator, the CPU 63 stores the number or multiplication operator determined to be input in the RAM 63. Then, the display device 23 is controlled to display the input-determined number or multiplication operator in the main area PU1 of the pop-up screen PU displayed on the display surface 23a (step S103). The pop-up screen PU illustrated in FIG. 6 is a pop-up screen PU that is displayed when the numeric key 22a “3” is pressed in step S101. A number “3” is displayed at a position close to the right end of the main area PU1.

  Then, after displaying the pop-up screen PU in step S102, the CPU 61 of the POS terminal 11 displays not only the numbers and multiplication operators determined to be input in step S101, but also the numbers determined to be input and the multiplication operators in the order of input. It is displayed on the main area PU1 (step S103).

  FIG. 7 is a schematic diagram illustrating a screen transition example of the pop-up screen PU. In FIG. 7, the detail screen AG is omitted and displayed.

  For example, when the numeric key 22a is pressed twice in succession and the CPU 61 of the POS terminal 11 makes a numeric input determination in the order of “3” and “4”, first, the CPU 61 of the POS terminal 11 is placed at the right end of the main area PU1. The pop-up screen PU displaying “3” is displayed (see FIG. 6). Next, the CPU 61 of the POS terminal 11 moves “3” to the left side to display “4” at the position where “3” was initially displayed, as shown in FIG.

  Further, for example, when the CPU 61 of the POS terminal 11 makes an input determination in the order of “3” and “X” by continuously pressing the “3” numeric key 22a and the multiplication key 22b, first, the CPU 61 of the POS terminal 11 Then, the pop-up screen PU on which “3” is displayed near the right end of the main area PU1 is displayed (see FIG. 6). Next, the CPU 61 of the POS terminal 11 moves “3” to the left side to display “x” at the position where “3” was initially displayed, as shown in FIG. 7B.

  Returning to the description based on FIG. FIG. 5 illustrates a case where the CPU 61 of the POS terminal 11 determines input in the order of “3” and “x”. Therefore, “3 ×” is displayed in the main area PU1 of the pop-up screen PU (see FIG. 7B).

  Here, when the CPU 61 of the POS terminal 11 performs input determination in the order of numbers, multiplication operators, and numbers (Y in step S105), based on the number of digits of the input determined after input determination of the multiplication operator (step S106). Step S107, Step S108), the attribute of the number input after the multiplication operator is determined.

  For example, when the number of digits determined after the input determination of the multiplication operator in step S105 is 1 digit or more and less than 8 digits (Y in step S106), the CPU 61 of the POS terminal 11 changes the input number to “product”. It is determined that the number is other than the code. In this case, the numeric input is performed mainly by pressing the numeric key 22a. Then, the CPU 61 of the POS terminal 11 displays the attribute-determined numbers in the main area PU1 of the already displayed pop-up screen PU as shown in FIG. 7C (step S112).

  In addition, when the number of digits determined to be input after the input determination of the multiplication operator in step S105 is 8 digits or more and less than 14 digits (N in step S106, Y in step S107), the CPU 61 of the POS terminal 11 is input. The number is determined to be a “JAN code” as a product code. In this case, numeric input is performed mainly by reading the barcode BC by the barcode scanner 101. Then, the CPU 61 of the POS terminal 11 displays the attribute-determined numbers in the main area PU1 of the already displayed pop-up screen PU as shown in FIG. 7D (step S113).

  Further, when the number of digits determined after the input determination of the multiplication operator in step S105 is 14 digits or more (N in step S106, N in step S107, Y in step S108), the CPU 61 of the POS terminal 11 It is determined that the input number is an “in-store code” as a product code. In this case, numeric input is made mainly by pressing the product key 22c. That is, an in-store code is assigned to the product key 22c, and the assigned in-store code is input when the product key 22c is pressed. Then, the CPU 61 of the POS terminal 11 displays the attribute-determined numbers in the main area PU1 of the already displayed pop-up screen PU as shown in FIG. 7E (step S114).

  Here, as shown in FIGS. 7C, 7D, and 7E, the CPU 61 of the POS terminal 11 first calculates the number “3” displayed in the main area PU1 and the multiplication operator. “X” is moved to the sub-area PU2 and displayed. The numbers and the multiplication operator are displayed near the right end of the sub area PU2 while maintaining the display order in the main area PU1. Then, the CPU 61 of the POS terminal 11 displays the attribute-determined number at a position near the right end of the main area PU1.

  If it is determined that the code is an in-store code, the 26-digit in-store code cannot be displayed in a line in the original main area PU1. Therefore, in step S114, as shown in FIG. 7E, the CPU 61 of the POS terminal 11 increases the thickness of the main area PU1 and displays the numbers that are the input in-store codes in two columns.

  By the way, after determining that the number input after the input determination of the multiplication operator in step S105 is a JAN code and displaying the number in the main area PU1 of the pop-up screen PU (step S113), the POS terminal 11 The CPU 61 controls the display device 23 to delete the pop-up screen PU from the display surface 23a (step S116). Similarly, even after determining that the number input after the input determination of the multiplication operator in step S105 is an in-store code and displaying the number in the main area PU1 of the pop-up screen PU (step S114), the POS terminal 11 CPU 61 controls the display device 23 to delete the pop-up screen PU from the display surface 23a (step S116). In this case, the CPU 61 of the POS terminal 11 is the “quantity” for the product specified by the product code input and determined after the input determination of the multiplication operator is the number determined before the input determination of the multiplication operator. Is determined.

  After deleting the pop-up screen PU (step S116), the CPU 61 of the POS terminal 11 searches the product master file MMF using the input product code (JAN code or in-store code) as a key, and corresponding product information (product Name, unit price) data is stored in the RAM 63. Then, the CPU 61 of the POS terminal 11 controls the display device 23 to display information (quantity, product information, etc.) stored in the RAM 63 in the current area AG3 of the detail screen AG (see also step S117, FIG. 4). .

  For example, a case where three “Sawayaka Kogen Milk” is purchased will be described. In this case, “3”, “×”, and “4988170113012 (product code of refreshing plateau milk)” are input to the POS terminal 11, and the CPU 61 of the POS terminal 11 performs input determination in this order. Then, in the pop-up screen PU deleted in step S116, as shown in FIG. 7 (d), “4988170113012” should be displayed in the main area PU1 and “3 ×” should be displayed in the sub area PU2. In this case, when the pop-up screen PU is deleted (step S116), as shown in FIG. 4, a character string “Sawayaka Kogen Milk” is displayed in the product name display area AG31 of the current area AG3, and the quantity display area AG32 “3” is displayed, and “180” and “540” (= 3 × 180) are displayed in the amount display area AG33. In the total quantity total amount display area AG34, the total quantity and the total unit price stored so far in the RAM 63 are calculated and displayed by the CPU 61 of the POS terminal 11. The information display on the current area AG3 is performed until another information display is provided to the current area AG3.

  As described above, the pop-up screen PU is deleted after the product code is displayed in the main area PU1 (Step S113, Step S114) (Step S116). By the way, there is a case where a discount is given to the unit price specified by the product code. For example, when performing a 10% discount, the operator continuously inputs “×”, “10”, and “discount instruction” to the POS terminal 11. That is, the operator first presses the multiplication key 22 b and inputs the multiplication operator “×” to the POS terminal 11. The CPU 61 of the POS terminal 11 pops up a pop-up screen PU in which “x” is displayed at the right end of the main area PU1 according to the input determination of the multiplication operator (steps S101 to S103). At this time, the CPU 61 of the POS terminal 11 restores and displays the information displayed on the pop-up screen PU deleted immediately before in the sub-area PU2 of the pop-up screen PU displayed as a pop-up. An example of the screen is shown in FIG. For example, the information displayed in the sub-area PU2 of the new pop-up screen PU, which is the information displayed in the pop-up screen PU that was deleted immediately before, is “3” as a quantity, multiplication operator “×”, The JAN code is “4987167013012”. These pieces of information are stored in the RAM 63. The CPU 61 of the POS terminal 11 displays information in the sub-area PU2 of the new pop-up screen PU based on the information stored in the RAM 63.

  Next, the operator presses the numeric key 22a and inputs the number “10”. “× 10” is displayed in the main area PU1 of the pop-up screen PU (step S103). Next, the operator presses the discount key 22g. As a result, a discount instruction is input to the POS terminal 11. In response to the input determination of the discount instruction, the CPU 61 of the POS terminal 11 determines 10 for the unit price specified by the product code input before the multiplication operator “×” and displayed in the subarea PU2. Execute% discount processing. The CPU 61 of the POS terminal 11 determines that the erasure instruction is input based on the discount instruction input determination. Therefore, the CPU 61 of the POS terminal 11 deletes the pop-up screen PU after determining whether to input a discount instruction. Then, the product information is displayed in the current area AG3. At this time, the unit price calculated by the 10% discount process is also displayed in the amount display area AG33.

  When it is determined that the number input after the input determination of the multiplication operator in step S105 is other than the product code and the number is displayed in the main area PU1 of the pop-up screen PU (step S112), the POS terminal 11 The CPU 61 continues to display the pop-up screen PU without deleting it, and executes post-processing (step S115). As an example of such processing, a case where a product A for which barcode barcode BC cannot be read by barcode scanner 101 for some reason is 10% discount will be described. In this case, first, a product code (JAN code) indicated by the barcode BC of the product A is input by pressing the numeric key 22a. Then, the multiplication key 22b is pressed to input a multiplication operator (steps S101 to S103). Next, “10” of 10% discount is input by pressing the numeric key 22a (Y in step S105, Y in step S106). At this time, “13-digit number corresponding to product code” and “×” are displayed in the sub area PU2 of the pop-up screen PU, and “10” is displayed in the main area PU1 (step S112). . This pop-up screen PU is not erased. Then, in the post-processing in the subsequent step S115, the operator next presses the discount key 22g. By pressing the discount key 22g, a discount instruction is input to the POS terminal 11. In response to the input determination of the discount instruction, the CPU 61 of the POS terminal 11 executes a 10% discount process for the unit price specified by the product code input before the multiplication operator “×”. The CPU 61 of the POS terminal 11 determines that the erasure instruction is input based on the discount instruction input determination. Therefore, the CPU 61 of the POS terminal 11 deletes the pop-up screen PU after determining whether to input a discount instruction. Then, the product information is displayed in the current area AG3. At this time, the unit price calculated by the 10% discount process is also displayed in the amount display area AG33.

  When reading of the barcode BC for all the products A stored in the first shopping basket 153a is completed, the operator of the POS terminal 11 presses the temporary closing key 22e. When the temporary closing key 22e is pressed, the microcomputer 60 of the POS terminal 11 pops up a payment screen (not shown) on the detail screen AG. At this time, the CPU 61 of the POS terminal 11 calculates the total amount to be paid by the customer based on the unit price stored in the RAM 63 and stores the calculated total amount in the RAM 63 in response to pressing of the temporary closing key 22e. ing. Therefore, the total amount stored in the RAM 63 is displayed on the payment screen. The total amount displayed on the payment screen is also displayed on the customer display device 24. The customer who sees the total amount displayed on the customer display device 24 deposits cash equivalent to the total amount or more to the operator of the POS terminal 11. The operator inputs a number corresponding to the deposited cash amount to the POS terminal 11 by pressing the number key 22a. At this time, the closing key 22f is pressed to confirm the input amount. The CPU 61 of the POS terminal 11 stores the input number as a deposit amount in the RAM 63 and displays it on the payment screen. Further, the CPU 61 of the POS terminal 11 calculates the difference when the deposit amount is equal to or greater than the total amount, stores the calculated difference in the RAM 63 as a change amount, and displays it on the payment screen.

  By the way, some customers want to make a part or all of the payment with cash vouchers such as gift certificates instead of cash. The operator who has been notified by the customer presses the payment selection key 22d after the temporary closing key 22e is pressed and a payment screen (not shown) is displayed. When the payment selection key 22d is pressed, a display instruction for the payment selection screen PG (see FIG. 8) is input to the POS terminal 11. The CPU 61 of the POS terminal 11 pops up the payment selection screen PG on the detail screen AG in response to the determination of the display instruction.

  FIG. 8 is a schematic diagram showing a state where the payment selection screen PG is displayed on the detail screen AG. The payment selection screen PG is a screen having a rectangular shape smaller than the detail screen AG. As shown in FIG. 8, in the state where the payment selection screen PG is displayed, the detail screen AG is grayed out. At this time, the touch designation by the touch panel 26 of each key included in the footer area AG4 of the detail screen AG is invalid.

  As shown in FIG. 8, the payment selection screen PG has a total amount display area PG <b> 1 for displaying the total amount stored in the RAM 63. A plurality of voucher keys PG2 are arranged in the lower area of the total amount display area PG1. On the upper surface of the cash voucher key PG2, “gift certificate”, “beer ticket”, and the like are displayed. A remaining amount display area PG3, which will be described later, is provided in an area below the voucher key PG2. And the payment selection screen PG has main area PU1 and subarea PU2 in the area | region below the balance display area PG3 similarly to pop-up screen PU.

  In a state where the payment selection screen PG is displayed, the same processing as that described based on the flowchart of FIG. 5 is executed. First, the number of gold vouchers (for example, “3”) is input by the operator pressing the numeric key 22a. When the CPU 61 of the POS terminal 11 determines input of a number corresponding to the number of vouchers, the CPU 61 displays the determined input number in the main area PU1 of the payment selection screen PG (step S103). Note that the pop-up screen PU is not displayed. Then, when the multiplication key 22b is pressed to determine the input of the multiplication operator, the number of numbers displayed in the main area PU1 of the payment selection screen PG is moved to the left, and the position where this number was initially displayed is moved. Instead of “x”, “sheets” are displayed as multiplication operators (step S103). After inputting the multiplication operator, the operator inputs the face value (for example, “500”) of the cash voucher with the numeric keys 22a (step S105). Since the number of digits input is less than 8 digits (Y in step S106), the CPU 61 of the POS terminal 11 determines that the face value of the cash voucher other than the product code is present. Then, the attribute-determined numbers are displayed in the main area PU1 of the payment selection screen PG (step S112). At this time, the CPU 61 of the POS terminal 11 first moves the number “3” displayed in the main area PU1 and the multiplication operator “sheets” to the subarea PU2 and displays them. The numbers and the multiplication operator (“3”) are displayed near the right end of the sub-area PU2 while maintaining the display order in the main area PU1. Then, the CPU 61 of the POS terminal 11 displays the attribute-determined number “500” at a position near the right end of the main area PU1 (see FIG. 8).

  In the subsequent post-processing (step S115), the multiplication key 22b and the cash voucher key PG2 are continuously pressed. By pressing the cash voucher key PG2 displayed as “gift certificate”, a payment instruction using a gift certificate is input to the POS terminal 11. When the CPU 61 of the POS terminal 11 continuously determines the input of the multiplication operator and the input of the payment instruction by the gift certificate, the number that is the number of coins determined to be input before the input determination of the multiplication operator and the input of the multiplication operator are performed. A number obtained by multiplying the number which is the face value of the voucher input and determined after the determination is calculated as the voucher amount. Then, the amount obtained by subtracting the voucher amount from the total amount displayed in the total amount display area PG1 is calculated as the remaining amount, stored in the RAM 63, and displayed in the remaining amount display area PG3 of the payment selection screen PG. When the determination key PG4 displayed as “OK” on the payment selection screen PG is pressed, the payment selection screen PG is erased and the above-described payment screen (not shown) is displayed. The remaining amount is displayed in the payment amount. The customer deposits cash corresponding to the remaining amount with the operator of the POS terminal 11. The operator inputs a number corresponding to the deposited cash amount to the POS terminal 11 by pressing the number key 22a. The CPU 61 of the POS terminal 11 displays the input number as a deposit amount on the payment screen. If the deposit amount is equal to or greater than the total amount, the difference is calculated as a change amount and displayed on the payment screen. The payment selection screen PG is deleted, and when the above-described payment screen (not shown) is displayed, if the remaining amount is negative, the change amount is calculated and displayed on the payment screen. If the balance is zero, the process ends.

  As described above, according to the present embodiment, numbers and multiplication operators are displayed in the input order in the main area PU1 and sub-area PU2, and when numbers are input after the multiplication operators are input, The numbers and operators displayed on PU1 move to sub-area PU2 and the newly input numbers are displayed on main area PU1. Thereby, the operator of the POS terminal 11 can confirm the input process performed by himself / herself. If the input of the multiplication operator is forgotten, the display is not moved, so that an operator input error is particularly noticeable. Thus, the operator of the POS terminal 11 can quickly find an input error.

  In the present embodiment, the pop-up screen PU including the main area PU1 and the sub area PU2 is displayed in response to pressing of the numeric keypad. Therefore, it is easy to visually distinguish other display elements (detail screen AG and the like) in the display surface 23a of the display device 23 from the main area PU1 and the sub area PU2. Thereby, the operator can confirm the input process more clearly.
