Description

  The present invention relates to a product data processing apparatus for automatically calculating and displaying a unit price including tax and a price when a unit price of a domestic tax product whose tax-excluded unit price is set to PLU (Price Look Up) is called. .

  There are two types of merchandise: tax-inclusive and tax-excluded. Domestic tax products were bought and sold at that price, and foreign tax products were bought and sold with the tax added to the price.

  In the case of a domestic tax product, a price including tax is set in the PLU, and in the case of an external tax product, a price excluding tax is set in the PLU.

  For example, when changing the price of a domestic tax product, the price including tax is input as it is.

Note that there is a description about changing the unit price (see Patent Document 1).
JP-A-5-35973

  For example, even if it is a domestic tax product, since the purchase is tax-excluded, there is a demand for setting a unit price without tax in the PLU.

  Consider the case where the tax-excluded unit price is set in the PLU for the domestic tax product. When operating with the tax-excluded unit price set for PLU for domestic tax products, as a product display method in the product registration mode, after calculating the tax rate for the tax-excluded unit price set in the PLU when calling the product There is a method of displaying the unit price (or price) including tax.

  Further, when changing the unit price of the product set in the PLU, it is difficult for the operator to change the unit price in consideration of the tax rate, so the unit price without tax is input. Then, after inputting the unit price without tax, the “confirm” key for calculating the tax is operated.

  In such a case, there is a problem that it is difficult to understand at a glance whether the unit price displayed in the unit price column for displaying the unit price is a unit price without tax or a unit price including tax.

  The present invention has been made in view of the above points, and the object thereof is product data processing that makes it easy to understand at a glance whether the unit price displayed when changing the unit price is including tax or excluding tax. To provide an apparatus.

  The present invention provides a product information file storing at least unit price data of a product, a calling unit for calling unit price data from the product information file, a tax-inclusive unit price obtained by adding a consumption tax to unit price data called by the calling unit. In a product data processing apparatus having a display means for displaying in a normal display state, a numerical value input means for inputting a numerical value, and a numerical value input by the numerical value input means on the display means in a normal display state Display control means for displaying on the display means in a different display state.

  According to the present invention, when the price of the tax-excluded product is set to PLU without tax, the display state for displaying the tax-excluded price is different from the display state for displaying the tax-inclusive price. It is possible to visually check whether the price is a tax-excluded price or a tax-included price.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an electronic fee balance as a product data processing apparatus, FIG. 2 is a diagram showing a key input unit of FIG. 1, and FIG. 3 is a block diagram showing a system configuration of the electronic fee balance.

  In FIG. 1, 1 is an electronic bill scale, 2 is a display unit for displaying various data, 3 is an LED (light emitting element), 4 is a keyboard as a numeric input means, 5 is a label issuing port, and 6 is the weight of the product. A load cell unit 7 that weighs and outputs weight data, and 7 is a scale unit for weighing products.

  Next, the keyboard 4 will be described with reference to FIG. The key input unit 4 includes an “erase” key 4a for clearing the numeric data, an “issue” key 4b for operating when issuing a label, a “wind” key 4c for registering and clearing the tare amount, and correction. “Correction” key 4d, “Fixed amount / weighing” key 4e that is operated when switching the fixed amount product number and weighing product number, “Paper feed” key 4f that feeds paper, and LCD 3 to turn off to prevent screen burn-in. A “standby” key 4g, a “number” key 4h to be operated when setting the number of packs, and a “product number” key 4i to be operated when calling a product number are provided.

  Next, a system configuration diagram of the electronic toll balance will be described with reference to FIG. In the figure, reference numeral 11 denotes a flash ROM (read only memory) 12 in which various programs as shown in the flowcharts of FIGS. 8 and 9 are stored, the PLU file 13a shown in FIG. 5, a RAM (Random Access Memory) 13 in which various work areas 13b are set, a scale interface 14 for fetching weight data from the load cell unit 6 described above, and a communication interface to which an external host computer is connected 15. Key controller 18 that takes in the operation signal from the keyboard 4 and the operation signal from the touch panel of the display unit 2 described above, display control for LCD (Liquid Crystal Display) that displays various setting screens, and display for controlling the lighting of the LED 3 Printing of the controller 19 and the printer 20 that issues the label The printer engine 21 to perform the control, transmission, reflection, I / O port 23 for transferring the data between the various sensors 22 such as temperature, are connected to the system bus 24.

  Next, the configuration of the PLU file 13a will be described with reference to FIG. As shown in the figure, the PLU file 13a stores a product name, a unit price type, a tax table, a JAN code, etc. for each product number. For example, data indicating the product name “potato salad”, the unit price type “weighing”, the unit price “200 yen”, and the tax table “1” is stored in the product number “2”.

  As shown in FIG. 5, the tax table 13b stores a tax type, a rounding error, and a tax rate for each tax table number.

  For example, although the tax classification of the product with the product number “2” in FIG. 4 is “1”, referring to this tax table 13b, the product with the product number “2” has “tax type” as internal tax. , “Rounding error” is rounded down and “Tax rate” is 5%.

  Next, an embodiment of the present invention configured as described above will be described with reference to the flowcharts of FIGS. First, the product registration (label issuance) mode is set, and the PLU call screen (FIG. 6) of “potato salad” of the product number “2” is called. This is performed by operating the product number “2” and “product number” key 4i of the potato salad. Here, since the product name “potato salad” is a domestic tax, the tax-excluded price “200 yen” is set in the PLU file 13a. Therefore, when called as shown in FIG. 6, the unit price is displayed in the unit price display area 51 as 210 yen. That is, 200 × 1.05 = 210. At this time, the price “210 yen” is displayed in black. If the weight of the product is “100 g”, all are displayed in black, which is a normal display state, as shown in FIG.

Hereinafter, as an example, a case where the unit price without tax of the product name “potato salad” is changed from “200 yen” to “180 yen” will be described. In this case, the numbers “1”, “8”, and “0” are entered from the keyboard 4.
Enter.

  Hereinafter, the operation when changing the unit price will be described with reference to the flowcharts of FIGS. 7 and 8. First, it is determined whether there is a unit price change numerical value input (step S1). That is, it is determined whether or not a numerical value is input to the unit price display area 51. In the electronic fee scale, in the product registration (label issuance) mode, all the numbers input from the keyboard 4 are displayed in the unit price display area 51.

  Since the numerical value is input from the keyboard 4 in this way, it is determined as “YES” in the determination in step S1.

  Next, it is determined whether the tax classification of the called PLU product is a domestic tax (step S2). Referring to the PLU file 13a and the tax table 13b in FIG. 4, it is determined that the tax type of the product name “potato salad” is internal tax. Accordingly, “YES” is determined in the step S2.

  Then, as shown in FIG. 11, the input number “180” is displayed in the unit price display area 51 in red different from the normal display state (step S3). That is, it is indicated by displaying in red that the unit price displayed in the unit price display area 51 is a unit price without tax. Moreover, as shown in FIG. 11, the price display area 52 is also a tax-excluded price. Reference numeral 50 denotes a weight display area in which the weight is displayed, and the areas 50 to 52 constitute display means.

  Next, in order to display the unit price including tax in the unit price display area 51, the “total amount” key 53 which is a change confirmation key is operated.

  By this operation, it is determined as “YES” in the determination of whether or not there is a change confirmation key input (step S4). As a result, the tax-inclusive price for the tax-excluded unit price “180” is calculated. That is, 180 × 1.05 = 189 yen is calculated. Accordingly, as shown in FIG. 12, the tax-included unit price “189” is displayed in the unit price display area 51 in black, which is the normal display state. If 100 g is set in the weight display area 50, “189” is displayed in the price display area 52 by multiplying the unit price and the weight (step S5).

  Next, the “issue” key 4b for issuing the label of the keyboard 4 is operated (step S6). Thus, when the “issue” key 4b is operated, it is determined whether or not the numerical value displayed in the unit price display area 51 is black (step S7). Here, the fact that the numerical value displayed in the unit price display area 51 is black display, which is a normal display state, means that the numerical value is a unit price including tax.

  If “YES” is determined in this step S 7, the label on which the product name, unit price, weight, price, etc. are printed by the printer unit 20 is discharged from the label issuing port 5.

  By the way, when the “issue” key 4b is not operated after the numerical value is input, “NO” is determined in the determination in step S4, and it is determined whether each setting key is input (step S9). Here, each setting key is a key such as a wind key or a part number key.

  Here, if “YES” is determined in step S9, each setting process for the wind key and the product number key is performed (step S10). That is, in step S9, when the wind key is pressed, the numerical value “180” displayed in red is moved to the tare area 54. When the product number key is pressed, product information corresponding to the product number “180” is called from the PLU 13a. Then, the display of the price display area 51 is returned to the numerical value “200” displayed before “180” displayed in red (step S11). That is, when a numerical value is input from the keyboard 4, if the product is a domestic tax, a numerical value input in red is displayed in the display unit price area 51. As a result, the operator can visually recognize that the unit price displayed in the unit price display area 51 is tax-excluded.

  On the other hand, when a setting key other than the “Issue” key 4 b is operated after a numerical value is input from the keyboard 4, the input numerical value is not a numerical value for changing the unit price. After performing the processing according to the operated setting key and the numerical value from the numerical value that has been operated, the previous unit displayed in red in the unit price display area 51, that is, the black display in the normal display state. Processing to return to the numerical value “200” is performed.

  By the way, if the operator intends to change the unit price and inputs “180” from the keyboard 4 and then forgets to operate the “total amount” key 53 and operates the “issue” key 4b, the price display area 51 is displayed. Since the display is not black, “NO” is determined in the determination in step S7, and an error display is made as shown in FIG. 13 (step S12). This error display can prompt the operator to press the “total amount” key 53.

  By the way, when it is determined as “NO” in the determination of step S2, when it is determined that the unit price of the product is a foreign tax, the input numerical value is displayed in black in the unit price display area 51 as it is (step). S13).

  In the above-described embodiment, red is displayed. However, any display state may be used as long as the display state is different from the normal display state. For example, blanking display, bold display, or a combination of these may be displayed.
