SOLUTION: In a label print-issued by an electronic change scale with a label printer, a numerical value of the price after a reduction of price is printed, this accords with numerical value data read out of a bar code. Also, the numerical value of a unit price after the price reduction is printed, and a unit price before a reduction of price is printed in a manner having correction lines put thereon. When price reduction registration operation and label issue instruction operation are conducted, a label is print-issued by depicting a unit price before the price reduction near the unit price as well as a unit price after the price reduction, weight, a unit price before the price reduction on a printing buffer 13-2, thereby print-issuing a label capable of recognizing an actual value of the price reduction correctly in comparison with a unit price before the price reduction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label printer which includes product data storage means for storing product data for each product, and prints sales data on a label based on the product data read from the product data storage means. About.

[0002]

2. Description of the Related Art In a conventional electronic fee scale with a label printer, the PLU (price look up) No. A PLU file storing product data (PLU No. data, product name data, unit price data, etc.) is provided for each product, and product data of products registered for sale is called from the PLU file.
Price data is calculated from weighing data obtained by measuring the weight of the product and unit price data, and a label printer is printed and issued with these various data as sales data by a label printer. By the way, when a discount sale is performed, for example, as shown in FIG. X1, the unit price 220 before the discount and the price 510 before the discount are printed as numerical values on the label with the discount, and the discount resulting from discounting the unit price 220 to 194 is displayed. The data of the later price 450 is written in a barcode, and when the product is registered for sale, the barcode is read. Therefore, the product "pork loin" is registered for sale at a discount price of 450 yen. As shown in this example, in a conventional electronic toll scale with a label printer, when discounting is performed, the data before printing is used for the printed numerical value and the data after discount is used for the barcode. Alternatively, a label with a price is printed and issued using the discounted data on the printed numerical value and barcode.

[0003]

In a conventional label printer, for example, an electronic toll scale with a label printer,
Only one data can be set (drawn) at the place where the unit price changed before and after the discount is printed as a numerical value. Only the unit price before the discount is printed, and the comparison between the before and after the discount is made. Because it was not possible, it was unknown whether the unit price was really discounted. Therefore, an object of the present invention is to provide a weighing label printer that can print and issue a label that allows a customer to accurately understand the effective value of a discount.

[0004]

The invention corresponding to claim 1 is:
A product data storage unit that stores product data such as a product name and a unit price is provided for each product, and a price is calculated from the unit price of the product data read from the product data storage unit and the weighed weight. In a label printer with a scale that prints sales data on a label, a unit price is changed by a unit price change unit that changes a unit price, a drawing unit that expands image data of sales data to a print buffer, and a unit price change unit. Then, calculate the price calculated by the changed unit price and draw the changed unit price, the price corresponding to the changed unit price in the print buffer, and place the unit price before the change near the changed unit price. And a printing means for printing the image data drawn in the print buffer on a label. .

As a process, it is determined whether or not a discount registration operation has been performed using any of the POS price key, POS discount key, and POS% discount key of the function keys of the one-touch key section. Here, when it is determined that the discount registration operation has not been performed, it is determined whether a normal registration operation has been performed. Here, if it is determined that the normal registration operation has not been performed, a process based on another operation is performed, and when the other operation process is completed, the registration mode process is terminated and the process returns to the main process again. Has become.

When it is determined that a normal registration operation has been performed, a price calculation is performed based on the weight (weighing data) obtained in the above-described step 1 and the called PLU data. LCD module 9
And the process proceeds to the process of step 4 (ST4) described later. In the processing of step 3 described above,
If it is determined that the discount registration operation has been performed, the discount flag 13-1 formed in the RAM 13 is set to 1 indicating that the discount registration has been made, and the weighing data obtained in the above-described step 1 is called out. The price is calculated based on the PLU data and the discount data obtained by the discount operation, the calculated price is displayed on the LCD module 9, and the process proceeds to the next step 4 (ST4).

In the process of step 4, it is determined whether or not an operation for issuing a label issuance instruction (for example, an operation of the ten key / function key unit 6 for a custody / current total key) has been performed. If it is determined that the label issuance instruction operation is not performed, the registration mode process is terminated and the process returns to the main process. When it is determined that the label issuing instruction operation has been performed, it is determined whether or not 1 has been set to the discount flag 13-1 as the process of step 5 (ST5). If it is determined that 1 is not set in the discount flag 13-1, that is, 0 indicating normal registration instead of discount registration, the unit price, weight (weighing data), and price are formed in the RAM 13. Is drawn (developed) in the printed print buffer 13-2 (drawing means), and the other print items (
The product name, barcode, date of manufacture, expiration date, etc.) are drawn in the print buffer 13-2 (drawing means), and labels are printed and issued. When this label issuance is completed, PLU file 1
The memory processing for performing the total processing (totaling processing) for the total memory and the journal memory of No. 4 is performed, and when this memory processing is completed, the registration mode processing is terminated and the processing returns to the above-described main processing again.

In the processing of step 5 described above, 1 is set to the discount flag 13-1. When it is judged that the price is reduced, the unit price, weight (weighing data), the price (after the discount), the unit price before the discount, and the correction line drawn over the value before the discount are drawn in the print buffer 13-2. (Drawing means, change drawing means), 0 is set to the discount flag 13-1. Next, other print items are drawn in the print buffer 13-2 by deleting a portion overlapping with the unit price before the discount (drawing means).
Print and issue the label (printing means). When the label issuance is completed, a memory process for performing a total process (totaling process) on the total memory and the journal memory of the PLU file 14 is performed. When the memory process is completed, the registration mode process is completed and the above-described main process is performed again. It returns to the processing.

In this embodiment having such a configuration, when the discount registration is performed by one of the POS price key, the POS discount key, and the POS% discount key of the one-touch key 7, the discount after the discount is performed. The unit price, weight, and discounted price are drawn in the print buffer 13-2, and, for example, when the unit price is reduced, the vicinity of the unit price (for example, the lower part) is displayed.
At the position, a unit price before the discount and a correction line are drawn on the unit price before the discount. Based on the data drawn in the print buffer in this manner, the label printed and issued is shown below the unit price “194” (after the discount) as shown in FIG.
Originally, the print data of “per 100 g (yen)” indicating the unit price should be printed. However, the unit price 220 before the discount is printed with the double correction line superimposed and drawn.

FIG. 9 described in the prior art shows this 100
100g unit price of 232g pork loin of 220g unit price
Using the same data discounted to 94 yen, this is printed and issued by a conventional electronic toll scale with a label printer.
