The second display unit displays a calculation screen on the touch panel 11jb, for example, according to a predetermined input operation set in advance. The third display unit causes the calculation screen to display a numerical value representing an amount selected by the operator's input operation on the item list screen (for example, the unit price of the item, the total amount for each item, the subtotal amount, etc.). The calculator performs calculations based on the numerical values displayed on the calculation screen.

The storage unit 11d stores data used when the processor 11a performs various processes or data generated by the processes of the processor 11a. As the storage unit 11d, for example, an EEPROM (registered trademark) (electric erasable programmable read-only memory), HDD (hard disk drive), or SSD (solid state drive) can be used.

The change dispenser 11e receives coins and banknotes that are thrown in, and discharges coins and banknotes as change.
The communication unit 11f communicates with a server or another product sales data processing device via the LAN 14, for example.

The scanner 11g reads product information by optical scanning, for example, and inputs a product code unique to the product. The scanner 11g may be a fixed or handy two-dimensional code scanner, or may be of a type that uses image recognition technology to identify products from photographed images of the products. Also, the scanner 11g may be provided with only one type, or may be provided with a plurality of types.

The touch panel 11h is a device for input operation by an operator (clerk), and includes a display device and a touch sensor. A display device displays arbitrary screens, such as a GUI (Graphical User Interface) screen. For example, the display device is used to input a list of transaction information (product name, price, etc.) and a registration screen (product list screen) including a subtotal amount, etc., various menus, and commands related to products registered as purchase targets. button, etc. A known device such as a color LCD (Liquid Crystal Display) can be used as the display device. The touch sensor is arranged over the display surface of the display device. The touch sensor detects the operator's touch position on the display surface of the display device and sends the position information to the processor 11a. A well-known device can be used as the touch sensor.

The combination keyboard 11j is a device for input operation by an operator (clerk), and has, for example, a keyboard 11ja on which a plurality of keys individually assigned with specific functions are arranged and a touch panel 11jb. The touch panel 11jb is configured similarly to the touch panel 11h, for example. The touch panel 11jb displays supplementary information that does not always need to be displayed, information that should be shared by operators in the store (bargain sale information, messages from the store manager, etc.), and the like. Further, when calculator processing is executed, a calculation screen (calculator screen) is displayed on the touch panel 11jb.

The printer 11k is, for example, a thermal printer or a dot impact printer, and prints various character strings, images, code patterns (barcodes, two-dimensional codes, etc.) on receipt paper to print product names, unit prices, Issue a transaction receipt or the like on which transaction details such as the total amount are printed.

The card reader/writer 11m reads data recorded on the card and writes data to the card.

Next, the operation of the product sales data processing device 10 according to the first embodiment will be described. When the product sales data processing device 10 is activated in a mode for registering products to be purchased, the processor 11a starts control processing based on the control program stored in the ROM 11b or the storage unit 11d.

When the control process is started, the processor 11a clears the registration product table recorded in the RAM 11c and displays the registration screen on the touch panel 11h. The registration screen is for displaying information about the products registered in the registered product table, and for allowing the operator to check the progress of the registration process.

When detecting that the product code attached to the product has been read by the scanner 11g by the operator's operation, the processor 11a registers (updates) the product information corresponding to the product code in the registered product table. In addition, the processor 11a updates the product information on the registration screen according to the contents of the updated registered product table. Thereafter, as described above, the processor 11a sequentially adds product information corresponding to the acquired product code to the registered product table each time the operator performs an operation to read the product code with the scanner 11g.

In this way, after at least one product has been registered, the processor 11a, for example, when detecting that the subtotal button has been operated, based on the contents registered in the registered product table, Generate transaction information for payment processing. The processor 11a causes the touch panel 11h to display a small plan screen including information such as a list of registered products, the total number of registered products and the total amount of money. Further, when detecting that the checkout button provided on the small plan screen has been operated, the processor 11a executes the settlement process based on the transaction information after the closing process for ending the registration process.

By the way, while the registration process is being executed by the operator's operation, the customer may request an irregular calculation. For example, as irregular calculations, for example, calculations such as the total amount limited to some designated products of multiple products to be purchased, tax-excluded calculations, tax-included calculations, etc., and data registered in the product file Calculating different prices, calculating temporary discounts or discounts, calculating the total amount based on that amount, calculating the amount when using a gift certificate, the amount of change, or the amount of per capita (split bill), etc. There is

In such a case, the product sales data processing device 10 can execute calculator processing according to the input operation on the calculator declaration key.

In the initial state before numerical data is input, the area R4 is blank.

Numerical value/calculation key area R5 includes, for example, numeric keys ([00][0]-[9]), four arithmetic symbol keys ([+][-][×][÷]), calculation execution keys ([=] ), clear key ([C]), tax calculation key ([tax not included] [tax included]), decimal point key ([ ]), etc. are arranged. Numerical data is input when the numeric key is selected, and calculation data is input when the four arithmetic key is selected. In the numerical value/calculation key area R5 shown in FIG. 6, an example of numerical value/calculation keys suitable for the four arithmetic calculations and [tax excluded] and [tax included] calculations is shown. It is possible to provide a dedicated calculation key (for example, a split bill key for instructing execution of calculation of the split bill amount).

The button area R6 is an area where keys (buttons) for instructing execution of specific processing through the calculator screen SC2 are displayed. In the example shown in FIG. 6, a return key R60 for returning the display screen to the original state, a customer-side display key R61 for setting the customer-side display to display the processing contents in the calculator process on the customer-side display 11n, and a calculator process. A calculator declaration key R62 is provided for instructing the execution of .

The touch panel 11jb is used to display other information when the calculator process is not being executed, and the numeric/calculation key area R5 and the customer surface display key R61 shown in FIG. 6 are displayed in accordance with the activation of the calculator process. shall be Note that the calculator declaration key R62 may always be displayed regardless of the execution of calculator processing, or may be displayed if a specific key on the keyboard 11ja or the calculator declaration key R31 on the registration screen SC1 is provided. It doesn't have to be. Furthermore, regardless of the execution of calculator processing, the numeric/calculation key area R5 and the button area R6 may always be displayed.

First, when the processor 11a detects that the calculator declaration key has been operated during execution of the registration process (Act 11, Yes), the calculator screen (numerical/calculation key area R5 and customer display key R61) is displayed on the touch panel 11jb. to wait for an input operation. Numerical data to be calculated can be input by inputting numerical keys provided in the numerical/calculation key area R5 of the calculator screen SC2 or by inputting numerical data on the registration screen SC1.

When the processor 11a detects a touch operation on the registration screen SC1 of the touch panel 11h (Act14, Yes), the processor 11a determines the numerical value (number) displayed in the area including the touch position, and stores the numerical data of the touch position (Act15). . Further, the processor 11a displays a number corresponding to the numerical data of the touch position on the calculation formula display area R4 of the touch panel 11jb (Act 19). Similarly, when a touch operation is performed on an area where other numerical values (numbers) are displayed, the processor 11a adds a number corresponding to the numerical data of the touch position to the previously displayed number. to display it in the calculation formula display area R4 of the touch panel 11jb (Acts 14, 15, 19).

In the registration screen SC1 shown in FIG. 5, after the area of the unit price "98" of the product E is touched, the area of the unit price "298" of the product B is touched, and the last touched area is highlighted. represents the state specified by . In the calculator screen SC2 shown in FIG. 6, the numerical values "98" and "298" selected in succession on the registration screen SC1 are displayed in the calculation formula display area R4.

In the calculator processing in the first embodiment, basically, calculation for adding the input numerical values is executed. Therefore, for example, when the numerical value "98" is selected on the registration screen SC1, the addition sign "+" is automatically displayed (inputted) following the numerical value "98" in the calculation formula display area R4. Therefore, for example, when obtaining the total price of a plurality of products, a calculation formula for adding numerical values can be input simply by continuously touching the area where the prices are displayed on the registration screen SC1. . In the calculator processing, multi-digit numerical data can be input by one-time touch operation on the registration screen SC1, so that the operation of inputting multi-digit numbers one by one is unnecessary and the input operation is simplified. can be done.

On the other hand, when the key displayed in the numeric/calculation key area R5 of the calculator screen SC2 is touched (Act16, Yes), the processor 11a stores data (numerical data or calculation data) corresponding to the touched key. (Act 17). Here, if the touched key is neither the calculation execution key ([=]) for instructing execution of calculation nor the tax calculation key ([tax excluded] [tax included]) (Act 18, No), the processor 11a The data corresponding to the selected key is displayed in the calculation formula display area R4 of the touch panel 11jb (Act 19). In other words, it is possible not only to input numerical data by the input operation on the registration screen SC1, but also to input arbitrary numerical data or arithmetic data by operating the numerical/calculation key area R5 of the calculator screen SC2. can be entered.

Further, when the processor 11a detects that the calculation execution key ([=]) or the tax calculation key ([tax excluded] [tax included]) for instructing execution of calculation on the calculator screen SC2 has been touched (Act18, Yes). , a calculation process is executed based on the calculation formula displayed in the calculation formula display area R4 (Act 111), and the calculation result is displayed in the calculation formula display area R4. For example, when the tax calculation key ([tax excluded] key) is touched, the processor 11a determines that the numerical data included in the calculation formula (total calculation formula) displayed in the calculation formula display area R4 is the tax-inclusive price. If so, the amount excluding tax is calculated and displayed as the calculation result instead of simply the calculation result of the calculation formula.

Calculations executed on the calculator screen SC2 can be cleared by, for example, a touch operation on a clear key ([C]), and another calculation can be performed again.

Further, when the operation of touching the customer-side display key R61 of the calculator screen SC2 is detected (Act12, Yes), the processor 11a sets the customer-side display, and inputs by operating the registration screen SC1 or the calculator screen SC2. The calculated contents and the like are displayed on the display 11n.

When the input data is displayed in the calculation formula display area R4 of the calculator screen SC2 (Act 19), the processor 11a displays the customer screen on the display 11n if the customer screen display is set (Act 110, Yes). (Act 113). On the customer screen, for example, the display contents displayed in the calculation formula display area R4 of the calculator screen SC2, that is, the input data or calculation results are similarly displayed. Alternatively, the processor 11a can create not only a simple calculation formula but also display data for making the content of the calculation easier for the customer to understand, and display it on the customer screen.

FIG. 7 is a diagram showing an example of the customer screen SC3 displayed on the display 11n. In the example of the customer screen SC3 shown in FIG. 7, instead of simply displaying the calculation formula, characters representing the product name corresponding to the numerical value to be calculated, the subtotal amount, and the calculation method (calculation without tax) are added. It is

When the customer screen SC3 shown in FIG. 7 is displayed, for example, when a numerical value is selected on the registration screen SC1, the product corresponding to this numerical value is determined, and the product name data is stored together with the numerical data. back. In addition, the character string "tax excluded" corresponding to the touched key (here, the [tax excluded] key) in the numerical value/calculation key area R5 of the calculator screen SC2 is displayed in association with the calculated numerical value "367 yen". Let

As a result, the customer can easily confirm the contents of the calculation executed by the operation of the operator by referring to the customer screen SC3 displayed on the display 11n.

In the above description, the registration screen SC1 is displayed on the touch panel 11h, and the calculator screen SC2 is displayed on the touch panel 11jb. can be

FIG. 8 shows an example of a state in which a registration screen SC41 and a calculator screen SC42 are displayed on the screen SC4 of the touch panel 11h. During the registration process, the processor 11a displays a registration screen SC41 in the same manner as the registration screen SC1 shown in FIG. When the activation of the calculator process is instructed by operating the calculator declaration key during the registration process, the processor 11a causes the calculator screen SC42 to be displayed overlapping the registration screen SC41 as shown in FIG. At this time, the processor 11a displays the calculator screen SC42 at a position where the numerical values of the registration screen SC41 are not hidden. Alternatively, the size or shape of the registration screen SC41 may be changed so as not to overlap with the calculator screen SC42 or to reduce the overlapping range.

As shown in FIG. 8, even when the registration screen SC41 and the calculator screen SC42 are simultaneously displayed on the screen SC4 on the touch panel 11h, it is possible to efficiently input calculation formulas using the registration screen SC41 in the same manner as described above. It is possible.
