As shown in FIG. 3, on the weighing screen of the touch screen 3, a person in charge name button 3a is displayed together with display fields for displaying an article name, a call number, a tare, a weight, a unit price and a price (price). , An item name button 3b and a subtotal button 3c are displayed. Although a large number of product name buttons 3b are generally provided, only six are shown in FIG.

As shown in FIG. 4, on the list display screen, a product to be purchased is displayed in a product list area 3d, and a total amount and a person in charge are displayed in a total area 3e. In the product list area 3d, the product name, price, call number, weight, and the like of the product to be purchased are displayed for each product. The list display screen also displays a designation correction button 3f, a scroll button 3g, a ticket selling button 3h, and the like, which will be described later.

Next, the operation of the electronic scale will be described with reference to the display screen of the touch screen 3 shown in FIGS. First, in a state where the weighing screen of FIG. 3 is displayed on the touch screen 3, when a clerk receives an order for a product to be purchased from a customer, the clerk places the product on the weighing dish 20 (FIG. 1) and The product is weighed to a predetermined amount while looking at the weight display column. After the weighing, the clerk touches his / her rep name button (for example, “Tamura”) 3a and then touches the corresponding product name button 3b, and the CPU 11 is associated with the product name button 3b from the product master storage unit 12a. The product name and unit price of the call number are read out and displayed in the product name display column, unit price display column, and the like. On the other hand, C
The PU 11 calculates the price, displays the calculated price in the price display column, and purchases the storage unit 1 of the person in charge.
2b (FIG. 2 (c)) stores the call number, the product name, the price, and the like of the product, and stores "0" in the stop flag. When a plurality of products are specified by the customer, the above operation is repeated for each product.

Thereafter, when the clerk touches the clerk name button 3a and then the subtotal button 3c, the CPU 11
Reads out the storage contents of the purchase schedule storage section 12b and displays a list display screen on the touch screen 3 as shown in FIG. Thus, the product to be purchased is displayed in the product list area 3d, and the name of the person in charge is displayed in the product list area 3d. On the other hand, the CPU 11
Accumulates the prices of the products for which the stop flag of the purchase storage unit 12b is “0” and displays the total price in the total area 3e.

Here, in order to cancel the purchase of some of the products to be purchased, the user first touches the designation correction button 3f, and then touches the name of the product to be canceled. The CPU 11 stores “1” meaning stop in the column of the stop flag of the product to be stopped in the purchase schedule storage unit 12b of FIG.
As shown in the list display screen after the cancellation of (b), the two lines are displayed together with the name of the product to be canceled, the price, the call number, and the like, so that the product to be canceled is displayed separately from other products.
Next, the CPU 11 recalculates the integrated value of the product whose stop flag in the purchase storage unit 12b is “0”, that is, the product whose stop flag is “1” (the product to be stopped).
Then, the integrated value of the product to be purchased, excluding, is calculated again and displayed as the total amount in the total area 3e as shown in FIG. 4B.

Thereafter, when the clerk touches the ticket selling button 3h, a label is issued. After the issuance of the label, the contents stored in the purchase storage unit 12b are transferred to the total storage unit (not shown) and cleared. The product list area 3d can be scrolled by touching the scroll button 3g.

As described above, the products listed in the product list area 3d can be selected and designated (canceled). Therefore, the transaction can be stopped quickly and easily without storing the product number corresponding to the product in advance. Further, since the two lines are overwritten on the product to be canceled and are displayed separately from other products, it is possible to easily grasp the product whose purchase schedule has been canceled.

In the above-described embodiment, the product to be discontinued is displayed with two lines superimposed on each other. However, as the display method, the product to be discontinued is distinguished from other products by, for example, color-coding or reverse display. Any display method can be used.

Incidentally, the touch screen 3 shown in FIG.
In the case of inputting numerical values in the respective display columns of call No., tare, unit price, and price, the following procedure is performed. As shown in FIG. 5, the stroke key unit 4 includes a ten key 4 a and a cancel key 4 b, and function keys of “call”, “tare”, “unit price” and “fixed amount” corresponding to each display field of the touch screen 3. 4c.

When the clerk presses the numeric keypad 4a while the weighing screen is displayed on the touch screen 3, as shown in this figure, instead of the number (unit price) displayed in the unit price column 3i of the touch screen 3, The pressed number is displayed. At the same time, the background color of the unit price column 3i changes. Next, when a function key (for example, a "tare" key) 4c corresponding to the display column for inputting the numerical value is pressed, the numerical value displayed in the unit price column 3i is displayed in the tare column.
As described above, since the background color is changed, it is possible to accurately input a numerical value to each display field of the touch screen 3 even if the person in charge changes while inputting. After that, when the cancel key 4b is pressed, the original unit price is displayed again in the unit price column 3i.

[0022]

As described above, according to the present invention,
Since the list of products to be purchased is displayed on the display, and a change in the transaction for the product to be purchased can be set by selecting the product displayed on the display,
Even if the product number is not stored in advance, the transaction can be changed quickly and easily. Further, since the canceled product is displayed separately from other products, it is possible to easily grasp the product whose purchase schedule has been canceled.
