Description

An embodiment of the present invention relates to a product sales data processing device and a data processing program.

In a store accounting system (checkout system) used in supermarkets, etc., a product is usually read by a product reader (scanner) to read the product code of the product purchased by the customer, so that the product is sold in the product sales data processing device (POS terminal). The sum of the prices of the above is calculated as the amount billed to the customer. When the product code of the product is read, the POS terminal is based on the tax-included classification and tax-exempt product included in the product information corresponding to the product code recorded in the product file in advance, and if it is a tax-included product, the tax-included price. And for tax-exempt products, only the product prices are totaled to calculate the amount billed to the customer.

In normal payment processing, by reading the product code, it is possible to execute the calculation based on the product information registered in the product file, but due to customer's request etc., the calculation cannot be executed only by reading the product code. May be required. For example, total amount limited to some designated products of multiple products to be purchased, calculation such as tax-excluded calculation, tax-included calculation, calculation at a price different from the data registered in the product file, temporary discount or discount Irregular calculations may be required, such as the amount of money, the total amount based on that amount, the amount of money when using a gift certificate, the amount of change, and the amount of per capita rate (splitting).

Conventionally, in such a case, a simple calculator, a so-called calculator, is prepared separately from the POS terminal, and the amount of goods and the like are sequentially input using the calculator to execute the calculation. For this reason, if a situation that requires irregular calculation occurs, the checkout business may be stagnant, and it is required to be able to respond efficiently.

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

When the processor 11a starts the control process, the processor 11a clears the registered product table recorded in the RAM 11c and displays the registration screen on the touch panel 11h. The registration screen is for displaying information such as products registered in the registered product table, and is a screen for allowing the operator to confirm the implementation status of the registration process.

When it is detected that the product code attached to the product is read from the scanner 11g by the operation of the operator, the processor 11a registers (updates) the product information corresponding to the product code in the registered product table. Further, the processor 11a updates the product information on the registration screen according to the contents of the registered product table after the update. After that, as described above, the processor 11a sequentially adds the product information corresponding to the acquired product code to the registered product table each time the operator is operated to read the product code by the scanner 11g.

In this way, after at least one product is registered, when the processor 11a detects that, for example, the subtotal button has been operated, the processor 11a relates to the product registered in the registered product table based on the content registered in the registered product table. Generate transaction information for payment processing. The processor 11a causes the touch panel 11h to display a subplanning surface including a list of registered products and information such as the total number of registered products and the total amount of money. Further, when it is detected that the accounting button provided on the subplanning surface has been operated, the processor 11a executes a settlement process based on the transaction information after performing a closing process for ending the registration process.

By the way, while the registration process is being executed by the operation of the operator, the customer may request an irregular calculation. For example, irregular calculations include calculations such as total amount limited to some designated products of multiple products to be purchased, tax-excluded calculation, tax-included calculation, and data registered in the product file. Calculation at different prices, calculation of temporary discounts and discounts and the total amount based on that amount, calculation of the amount when using gift certificates, the amount of change and the amount of per capita rate (splitting), etc. There is.

In such a case, the product sales data processing device 10 can execute the calculator processing in response to the input operation for the calculator declaration key. In the calculator processing, using the registration screen that displays the price of the product, etc., the calculation according to the input operation is executed regardless of the calculation for the payment processing for the purchased product, which is executed by reading the product code. can do. The calculator declaration key is provided on, for example, at least one of a registration screen displayed on the touch panel 11h, a specific key on the keyboard 11ja, or a screen on the touch panel 11jb.

Next, the calculator processing in the first embodiment will be described. FIG. 4 is a flowchart showing calculator processing. FIG. 5 is a diagram showing an example of the registration screen SC1 displayed on the touch panel 11h when the calculator processing of the first embodiment is executed, and FIG. 6 is an example of the calculator screen SC2 displayed on the touch panel 11jb of the first embodiment. It is a figure which shows.

The registration screen SC1 shown in FIG. 5 includes areas R1, R2, and R3. The area R1 includes an area for displaying the product name, quantity, and unit price R11 related to the product finally registered in the registered product table, and the total number and total amount R12 of the purchased products after the product is registered.

The area R2 is for displaying a list of product names R21, quantity R22, unit price R23, and total price R24 (quantity x unit price) for products registered before the product shown on the registration screen SC1. Includes area. The registration screen SC1 shows only the basic form for displaying various information related to the registered product, and it is also possible to display various information related to product registration other than those shown in FIG. .. As shown in FIG. 5, on the registration screen, numerical values (numbers) are displayed in the areas of the unit price R11, the total amount R12, the number R22, the unit price R23, and the total amount R24.

The area R3 is an area in which a key (button) for instructing execution of a specific process is displayed through the registration screen SC1. In the example shown in FIG. 5, a discount key for individually discounting products to be registered, a discount key for similarly discounting, and a calculator declaration key R31 for instructing execution of calculator processing. Is provided.

The calculator screen SC2 shown in FIG. 6 includes a calculation formula display area R4, a numerical value / calculation key area R5, and a button area R6. The calculation formula display area R4 is an area in which the calculation formula to be calculated is displayed according to the numerical data or the calculation symbol input according to the input operation. In the example shown in FIG. 6, for example, a state in which numerical data [98], an operation symbol [+], and numerical data [298] are input is shown. In the initial state before the numerical data is input, the area R4 is blank.

In the numerical value / calculation key area R5, for example, a numerical value key ([00] [0] to [9]), an arithmetic symbol key ([+] [-] [×] [÷]), and a calculation execution key ([=]) ), Clear key ([C]), tax calculation key ([tax excluded] [tax included]), decimal point key ([・]), etc. are arranged. Numerical data is input when the numeric key is selected, and arithmetic data is input when the four-rule symbol key is selected. The numerical value / calculation key area R5 shown in FIG. 6 shows an example of the numerical value / calculation key suitable for the four arithmetic operations and the calculation of [tax excluded] and [tax included], but the calculation required by the customer is assumed. It is possible to provide a dedicated calculation key (for example, a split bill key for instructing the calculation execution of the split bill amount).

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

The touch panel 11jb is used for displaying other information when the calculator processing is not executed, and the numerical value / calculation key area R5 and the customer surface display key R61 shown in FIG. 6 are displayed according to the activation of the calculator processing. It shall be. The calculator declaration key R62 may be displayed at all times regardless of the execution of the calculator processing, and is displayed if the specific key of the keyboard 11ja or the calculator declaration key R31 of the registration screen SC1 is provided. It doesn't have to be. Further, the numerical value / calculation key area R5 and the button area R6 may be displayed at all times regardless of the execution of the calculator processing.

First, when the processor 11a detects that the calculator declaration key has been operated during the execution of the registration process (Act11, Yes), the processor 11a displays the calculator screen (numerical value / calculation key area R5 and customer surface display key R61) on the touch panel 11jb. Then, it is in the input operation waiting state. Here, the numerical data to be calculated can be input by an input operation for the numerical key provided in the numerical / calculation key area R5 of the calculator screen SC2 or an input operation for the 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 a 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 in the calculation formula display area R4 of the touch panel 11jb (Act 19). Similarly, when a touch operation is performed on the area where another numerical value (number) is displayed, the processor 11a continues the number corresponding to the numerical data of the touch position to the previously displayed number. Then, it is displayed 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, the area of the unit price "98" of the product E is touched, then 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” continuously selected on the registration screen SC1 are displayed in the calculation formula display area R4.

In the calculator processing in the first embodiment, it is basically assumed that the 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 symbol "+" is automatically displayed (input) in the calculation formula display area R4 following the numerical value "98". Therefore, for example, when calculating the total price of a plurality of products, it is possible to input a calculation formula for adding numerical values simply by continuously touching the area where the price of the registration screen SC1 is displayed. .. In the calculator processing, since it is possible to input multi-digit numerical data by one touch operation on the registration screen SC1, it is not necessary to input the multi-digit numbers one by one, and the input operation is simplified. Can be done.

On the other hand, when the key displayed in the numerical value / calculation key area R5 of the calculator screen SC2 is touched (Act16, Yes), the processor 11a stores the data (numerical data or calculation data) corresponding to the touched key. (Act17). Here, if the touched key is not the calculation execution key ([=]) for instructing the calculation execution and the tax calculation key ([tax excluded] [tax included]) (Act18, No), the processor 11a is touched. The data corresponding to the key is displayed in the calculation formula display area R4 of the touch panel 11jb (Act 19). That is, not only the numerical data can be input by the input operation on the registration screen SC1, but also the arbitrary numerical data or the calculation data can be input by the operation on the numerical value / 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]) instructing the calculation execution of the calculator screen SC2 is touched (Act18, Yes). , The calculation process is executed based on the calculation formula displayed in the calculation formula display area R4 (Act111), 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 sets the tax-included price by the numerical data included in the calculation formula (total calculation formula) displayed in the calculation formula display area R4. If it is expressed, the amount excluding tax is calculated and displayed as the calculation result, not simply the calculation result of the calculation formula.

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

When the operation of touching the customer surface display key R61 on the calculator screen SC2 is detected (Act12, Yes), the processor 11a sets the customer surface display and is input by the operation on the registration screen SC1 or the calculator screen SC2. The calculated calculation contents and the like are displayed on the display 11n.

The processor 11a displays the customer screen on the display 11n when the input data is displayed in the calculation formula display area R4 of the calculator screen SC2 (Act19) and when the customer side display is set (Act110, Yes). (Act113). On the customer screen, for example, the display content displayed in the calculation formula display area R4 of the calculator screen SC2, that is, the input data or the calculation result is displayed in the same manner. Alternatively, the processor 11a can create not only a simple calculation formula but also display data for making the calculation content easier for the customer to understand and display it on the customer screen.

FIG. 7 is a diagram showing an example of the customer surface 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 indicating the product name, subtotal amount, and calculation method (calculation excluding tax) corresponding to the numerical value to be calculated are added. Has been done.

When displaying the customer screen SC3 shown in FIG. 7, 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. deep. In addition, the character string "tax excluded" corresponding to the key touched in the numerical value / calculation key area R5 of the calculator screen SC2 (here, the [tax excluded] key) is displayed in association with the numerical value "367 yen" of the calculation result. Let me.

As a result, the customer can easily confirm the calculation content executed by the operation of the operator by referring to the customer surface 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. For example, the registration screen and the calculator screen are displayed on one touch panel 11h. You may.

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

As shown in FIG. 8, even in the form of displaying the registration screen SC41 and the calculator screen SC42 at the same time on the screen SC4 on the touch panel 11h, it is possible to input an efficient calculation formula using the registration screen SC41 in the same manner as described above. It is possible.

In this way, in the product sales data processing device 10 of the first embodiment, by executing the calculator processing, numerical data is input using the registration screen SC1 displayed by the registration processing, and through the calculator screen SC2. Arbitrary numerical data and arithmetic data can be input, and arbitrary calculation formulas can be easily input. Therefore, for example, in the registration process, even when the customer requests an irregular calculation of the product purchased by the customer, the calculation can be efficiently executed.
