BACKGROUND OF THE INVENTION
Price and unit price calculation method for a price scale with a printer that has a function to calculate the price of a product based on the unit price and the measured weight value, and to display a price scale that displays each value and a label that prints each value. About.
[0002]
[Prior art]
Conventionally, with this type of charge scale, a unit price corresponding to the product is set in advance, and when the product is placed on a measuring instrument, the price is calculated and each value is represented. When these values are printed by a label printer, the label is mostly attached to a product. As a special one, after setting the unit price, there is a function that adds a function for calculating and displaying a weight value in order to obtain a price desired by the customer. This is a convenient way to know how much weight you should pay when you say that you want △△ yen worth of a product with a unit price of XX yen when selling roses such as meat and boiled beans. It is a function. There are a face-to-face sales method that sells using such a charge scale and a prepack method that is performed at supermarkets. In particular, in the prepack method, a function of calculating and displaying a weight value for making a product a fixed price is effective. Some products, such as fish and fruits, are extremely difficult to adjust to their weight values, and it is also possible to replace them with other items, but this requires a lot of labor. Become.
[0003]
In addition, there are cases where fresh foods such as fish are discounted at supermarkets depending on the time of day. This is often seen when handwritten. An invention for issuing these discounted label issuance by an electronic cash register is disclosed in Japanese Patent Laid-Open No. Hei 8-202956. This invention has a bar code indicating that it is an object of price reduction, and if the time for price reduction comes, it will be processed, or by selecting the timing to apply the bar code for price reduction, it will be sold at any time Here, the weight element is not included for the register. Japanese Patent Laid-Open No. 8-202955 discloses an invention for providing a price reduction service to a fixed customer who frequently visits a store. In the present invention, the customer number and the visit date are stored in association with each other, and the store visit interval and the discount data are stored in association with each other. By entering the visitor number, the previous visit date can be known, and therefore the visit interval can be determined. Therefore, the above stored data is intended to differentiate by increasing the price reduction for customers who visit frequently and reducing the price reduction for customers who visit frequently. Again, the weight element is not included because of the register.
[0004]
[Problems to be solved by the invention]
In the prior art as described above, it has been described that it takes effort to adjust the product to the target weight or target price. However, in order to obtain a constant weight or a constant price, a combination weigher is also used. However, since it is expensive, there is a problem that it is difficult to purchase at a small retail store. In addition, since there is no unit price display for products pre-packed to a constant weight value, there is a problem that it is difficult for consumers to know what quality level, and there is a movement to require unit price display. However, the conventional technology cannot cope. Therefore, the present invention executes a discount process if the unit price after the discount is within the unit price allowable range of the product with respect to the price that the seller wants to sell when the discount is to be performed, Display actual weight and discounted price. Also, the unit price, actual weight and price by the above discount are printed on the label, and the unit price printed by the above processing will be slightly different even for the same product. In order to give customers a sense of cheapness, they provide a method that can realize these functions with a charge scale with a printer, and provide a weight tolerance instead of a unit price tolerance for discounts. It is an object of the present invention to provide a method that can achieve the same purpose.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention reads the information input from the operation key unit and the measured weight value into the calculation control unit in the charge scale with a printer, and sets the target price, the unit price allowable range or the target unit price and the weight allowable value. The range is stored in the calculation control unit, and a stage for determining whether or not the target price is set is provided. If the target price is not set, normal charge calculation is performed. If the target price is set, the target price is set. The unit price is calculated backward by price and weight, and if the unit price is within the allowable unit price range set in advance, the calculated unit price, target price, weight, etc. are displayed, and if necessary, the displayed content is labeled. If the calculated unit price is out of the above unit price tolerance range, the unit price is blanked or displayed as a symbol, or displayed and printed outside the box. It was configured to distinguish. In addition, when the weight allowable range corresponding to the target price and the target unit price are set instead of the unit price allowable range, the assumed weight is calculated back by the target price and the target unit price, and the assumed weight is set. If the value is within the range, the unit price calculated in advance and the target price and weight will be displayed and printed. If the assumed weight is outside the allowable weight range, the calculated unit price will be blank or displayed as a symbol. Or it was configured to be displayed and printed outside the box.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In this invention, the seller discounts the price of a prepacked product as a service to the customer for a limited date or time, and tries to attach a label so that the customer can know the discount well. When the target price and the target unit price tolerance are set, the unit price is calculated backward from the target price and weight, and if the seller wants the unit price, the discounted price, the discounted unit price and other data are immediately The company intends to promote sales by printing on a label and attaching the label to a product so that the customer can clearly understand that the price has been reduced.

【Example】
FIG. 1 is a block diagram showing the internal configuration of a charge scale with a printer according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a price / unit price calculation method. FIG. 3 is a perspective view of the charge scale with a printer. 1 and 3, 1 is a weighing unit having a platform on which products are placed, 2 is an A / D converter that converts an analog output from the weighing unit into a digital weighing signal, and 3 is a reading storing a program. It is an arithmetic control unit composed of a dedicated memory ROM, a readable / writable memory RAM used for arithmetic operations, etc., and an arithmetic device CPU that has input / output I / Os and executes various arithmetic processes according to programs. The weight signal transmitted from the A / D converter 2 is input to the calculation control unit 3, and the unit price, the target price, and the unit price allowable range are set to the calculation control unit via the key controller 6 by operating the operation key unit 7. 3 is input. Now, when the unit price is input from the operation key unit 7, the price of the product is calculated based on the weight of the product. When the unit price, target price, and unit price allowable range are input in the same manner as described above, the unit price is calculated based on the weight of the product placed on the platform and the target price, and if the unit price is within the unit price allowable range, the unit price is displayed. The unit price, the price, the weight value calculated in this way, the set value previously set by the operation key unit 7 and the like are displayed on the display unit 5 through the display controller 4. In this display unit, the unit price is displayed at 11, the weight is displayed at 12, and the price is displayed at 13. At the same time, these values are printed on a label or roll paper by a printer 10 by a printer control unit 9 that drives and controls the printer. Reference numeral 14 denotes an exit from which the printed paper is issued. A power supply unit 8 supplies necessary power to each element.
[0008]
Next, a method for calculating the price / unit price will be described with reference to the flowchart of FIG. In step S1, the information from the operation key unit 7 and the weight signal transmitted from the weighing unit 1 via the A / D converter 2 are read into the arithmetic control unit 3 and processed into weight value data for display. Then, it is determined whether or not various operation keys have been pressed. If YES, the process proceeds to various key processes in step S3. This key process is a process related to weight such as taring, zero reset, etc., and if it is a unit price, it is stored in the unit price memory in the arithmetic control unit 3 by input from the numeric keypad, and if it is a target price, it is also stored in the target price memory. Is done. In step S4, it is determined whether or not the original price calculation processing is performed. If YES, the price is calculated by multiplying the unit price of the product previously stored in step S3 and the weight value read in step S1 in step S5. Is calculated. The selection in step S4 is automatically determined depending on whether or not the target price is set. When the target price is not set, the process proceeds to step S5. When the calculation process in step S5 is completed, unit price, weight, and price are displayed on the display unit 5 by the display controller 4 in step S11. In step S13, whether or not to print is selected. When printing is performed, the answer is YES, and in step S14, various data is printed. The printer control unit 9 performs printing on the printer 10, and the process returns to step S1. If printing is not required in step S13, the process returns to step S1 as it is. Here, as described above, the discounted price and the discounted unit price are displayed at the same time if the price that the seller wants to sell for the purpose of discounting is within the unit price allowable range by back-calculating the unit price. If the weight of the product is within the weight tolerance instead of the unit price tolerance, the display is the same as above. This method is described in detail below because of the main requirements of the present invention. If the target price is set, step S4 is NO, and if the unit price allowable range is set in step S6, the unit price is calculated backward in step S7, and whether the unit price is within the unit price allowable range is determined in step S8. If it is within the range, the determination becomes YES, and the process proceeds to step S11 where the unit price, weight, and price are displayed. In this case, the unit price is the value calculated in step S7, and the weight is displayed as the true weight. If NO in step S8, the process proceeds to step S12, and the unit price display is blanked, displayed symbolically, or displayed outside the box, and only the weight and price are displayed within the specified frame, and distinguished from the products within the unit price allowable range. To do. After this, the process proceeds to step S13. If a weight tolerance is set instead of the unit price tolerance, step S6 is NO, the process proceeds to step S9, an assumed weight is calculated from the target price and the target unit price, and if it is within the weight tolerance in step S10, it is YES. Proceed to step S11. The display in this case is the weight determined by the target unit price and the target price desired by the customer. If step S10 is NO, the process proceeds to step S12 and the display is the same as the display described above.
[0009]
The above operation will be described below with an example. If the product is a prepacked product, the unit price is 500 yen per 100 g, and there are three types of prepacked products A to C, the normal charge calculation is as follows. Price of A = unit price (500 yen / 100 g) × weight 500 g = 2500 yen. Price of B = unit price (500 yen / 100 g) × weight 510 g = 2550 yen. Price of C = unit price (500 yen / 100 g) × weight 480 g = 2400 yen. Therefore, if the seller decides to discount the day or time and sells all of the above products for a flat price of 2200 yen, and wants to make the discounted unit price within the range of 450 yen ± 10 yen per 100g, Each is calculated as follows. Unit price per 100 g of A = target price (2200 yen) / 500 g × 100 = 440 yen. B unit price per 100 g = target price (2200 yen) ÷ 510 g × 100 = 431 yen. Unit price per 100 g of C = target price (2200 yen) ÷ 480 g × 100 = 458 yen. Since A product and C product are within the unit price tolerance range, the unit price, weight and uniform price calculated in reverse are displayed, and when reapplying the label, the label is printed and the label is pasted first and pasted instead of the label Is done. Therefore, the customer can understand the state of discount well. For product B, which has become too cheap because it is out of the unit price tolerance, the unit price label printing is blank, symbolic, or marginal display, so it is distinguished from the discounted product to be sold now. It becomes easy. In addition, if the seller sets the limit of the discount to the weight allowable range instead of the unit price, and the discount unit price per 100 g is 450 yen, the target weight standard is the target price (2200 yen) ÷ unit price (450 yen / 100 g) ≒ 489 g Become. Therefore, if the upper and lower range is ± 15 g, the allowable weight range is 474 g to 504 g. Therefore, since the A product and the C product are within the allowable weight range, they are printed at the specified position on the label. The values are the same as when the unit price allowable range is set, and the unit price, weight, and price of the A product are unit price 440 yen / 100 g, weight 500 g, and price 2200 yen. Since the B product is too heavy to deviate from the allowable weight range, the label printing of the unit price display is blanked, symbolized, or displayed outside the margin and distinguished from the discounted product to be sold now.
[0010]
【The invention's effect】
There are times when it is desired to sell pre-packed goods at a limited date or time for sales promotion and service to customers. At this time, by setting the discount target price, and setting the allowable unit price range or weight allowable range when discounted at the same time, the unit price is calculated back to the label indicating that the seller has reduced the price, and the unit price and weight It is possible to display and print prices and the like, and in particular, it has the effect that the reduced unit price is well known to customers and sales are promoted. In addition, there are times when you want to provide a fixed amount of pre-packed products as well as discounts, but only products that are within the unit price tolerance or weight tolerance that is the limit desired by the seller will be displayed and printed at the specified location, so the yield There is also an effect that is good.
