Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a digital display scale suitable for application to so-called face-to-face sales.

``Prior art'' Recently, electronic scales (digital display scales) have been developed that automatically calculate the price by setting the unit price of a product and measuring its weight, and also display this price digitally on the display. being developed.

``Problems to be solved by the invention'' When conducting sales operations using such digital display scales, it is particularly important to store sales at stores with large sales areas, such as large markets, where store staff follow customers while selling. During so-called face-to-face sales, even if multiple products are purchased from the same customer using several digital display scales closest to each purchase location, payment will be made all at once when the last product is purchased. It is desirable that the process be possible.

Furthermore, it is customary to issue a sheet to the customer on which the weight, unit price, price, total price, date, etc. of the purchased product are printed at the end of the sale of the product. Furthermore, when conducting face-to-face sales using multiple digital display scales, it is especially important that the unit price data for the same product be the same no matter which scale is used to weigh the product. If the unit price preset memory is provided in each digital display scale and the unit price is stored in this memory in advance, it is possible to avoid operational errors when setting the unit price in the preset memory or when changing the set unit price. Due to an operational error, there is a possibility that the unit price of the same product may differ depending on the weighing scale.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a digital display weighing device suitable for use in face-to-face sales where customers purchase items while moving around the store.

"Means for Solving the Problems" In order to solve the above problems, the present invention sets the unit price of a product and measures its weight, calculates the price by multiplying the unit price and weight, and stores the price data. In a digital display weighing device configured to digitally display the contents on the display section, there are a plurality of electronic scales installed at various locations in the sales floor, and each electronic scale is provided with product data including price data for each customer. an input means for inputting attribute data for differentiation; an operating means provided on each electronic scale for calling up the unit price of the product; and an operation means connected to the plurality of electronic scales and storing the unit price of the product in advance. At the same time, when the operating means is called, the pre-stored unit price data of the product is transferred to the electronic scale, and when the input means is input, sales data corresponding to the products weighed by each electronic scale are transferred. an aggregation means for aggregating the price data for each customer;
a control means for controlling the display of the cumulative total on the display section of the electronic scale; a printing means for printing the sales data compiled in the totaling means for each customer and issuing a receipt; The present invention is characterized by comprising a print command means for commanding the issuance of another receipt.

"Operation" In the above configuration, the store clerk weighs the product purchased by the customer on the nearest digital display scale, calculates the price of the product, and then, if the customer has the intention to purchase other products, Then, instead of performing payment processing (transferring money and issuing a receipt), attribute data for identifying this customer is input. As a result, the calculated price data and the like are stored in association with the attribute data.

The stored data is then transferred to another display scale via a connecting means as necessary, and the cumulative price of products purchased by the same customer is calculated and displayed on the display section.

Therefore, the customer purchased the last item,
In other words, by displaying the cumulative price of the products the customer has purchased up to that point on the display scale at which the customer has indicated that they have finished purchasing the product, payment processing can be performed all at once, and a receipt can be issued. .

In addition, when calculating the price of the above products, the common unit price data stored in advance in the aggregation means is
It is called and used as appropriate by its name.

"Embodiment" Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The electronic scale of this embodiment has a product weighing function, a price calculation function, a price display function, etc., and by operating the keys on the operation section of each electronic scale, preset values can be set in the totalizer to be described later. The unit price or single item price of a specific product can be called up and used when selling the product, and the products to be sold can be registered in the tabulator by category, item, customer, etc. On the other hand, a tabulator has the function of categorizing and tabulating the data output from each electronic scale when selling a product by category, item, etc., but by operating the keys on the operation panel of the tabulator, the unit price of a specific product can be calculated. , the single item price is preset in the internal memory of the tabulator. The printing device also has a function of printing output data from the electronic scale for each customer.

FIG. 1 is an overall configuration diagram of this embodiment. In this embodiment, four electronic scales (digital display scales) 1 (1 ₁ to 1 ₄ ) of the same type are connected to each other by three cables 3. A fourth electronic scale 1 ₄ is connected to the totalizer 2 via a cable 4 . In addition, four printing devices 5 are connected to the totalizer 2 and the cable 65
(5 ₁ , 5 ₂ , 5 ₃ , 5 ₄ ) are connected. The four printing devices 5 ₁ to 5 ₄ each have a customer key A, which is provided in the four electronic scales 1 ₁ to 1 ₄ , respectively.
B, C, and D (input means for inputting attribute data for distinguishing product data by customer). As a result, as will be described later, data such as the weight and price of the products weighed by each of the electronic scales 1 ₁ to 1 ₄ is sent to the corresponding customer memory of the totalizer 2 via the cables 3 and 4 and stored therein. At the same time, the weight, unit price, etc. of the products purchased by the customer so far are displayed on the printing device 5 corresponding to the customer-specific keys A, B, C, and D of the electronic scale 1 where the customer made the last purchase and calculated the total price. Receipt 66 with price, total price, date etc. printed
is beginning to be published.

Next, the configuration of the electronic scale 1 will be explained with reference to FIGS. 2 to 4. This electronic scale 1 is roughly divided into a display section 6, a weighing plate 7, an operation section 8, an AD converter, an arithmetic circuit, and
It consists of a control circuit, memory, display control circuit, etc. In the figure, 9 is a connector connected to the cable 3 or 4, and 31 is a power switch. The display section 6 includes a 4-digit weight display section 10, a 4-digit unit price display section 11, a 5-digit price display section 12, a net amount display section 13, a tare amount display section 14, an error display section 15, and a 1-digit classification section. Display section 16, total for each customer A(B,
C, D) Display sections 17, 18, 19, and 20 are provided, respectively. The net amount display section 13 is lit when the product is being tared and weighed, and the tare amount display section 14 is lit.
is lit when the weight is negative (less than zero) or when displaying the tare weight, and furthermore, the error display section 15 is lit when an error occurs such as when the price display section 12 overflows.

Further, in the total price display sections 17 to 20 for each customer, the one corresponding to the customer for whom the total price has been calculated is lit so that customers can be distinguished. Each of the above display sections 13~
15, 17 to 20, light emitting diodes are used as display elements. Further, the classification display section 16 includes a classification key 23 and a numeric key 2 for registering the classification of this product in the totalizer 2 when selling the product, as described later.
When you operate 1, a number representing the category will be displayed. In this embodiment, products can be classified into up to seven categories, and for example, in the case of a product corresponding to category 3, the number "3" is displayed on the category display section 16.

It consists of the number "9" and the keys "X", ... "XV" with Roman numerals written on the key tops.
As will be described later, the electronic scale 1 of this embodiment stores specific products (15 types) whose items and classifications are specified by operating keys on the operating section of the tally device 2 in the memory of the tally device 2. The unit price or the price of individual items can be preset for each electronic scale. After setting the preset data call key 31 of the electronic scale 1 to the ON position (ON in the figure), press the number key 21 corresponding to the product currently on sale (for example, key "5" or "XI", etc.). When pressed, the preset unit price of the product is called up from the tally unit 2 to the electronic scale. Therefore, there is no need to operate the numeric keypad to set the unit price or single item price on the electronic scale 1 for such specific products. On the other hand, if the product does not have a preset unit price, the unit price is set using the numeric keypad. The single item key 22 is used for products to be sold without being weighed, and after operating the single item key 22, the price of the product is input into the electronic scale 1 using the numeric keypad. As described above, the classification key 23 and item key 30 are used to classify products and use the tabulator 2 for each item.
This is used to register in the memory by category and item within the system. After setting the classification using the number keys 21, operate the classification key 23, then set the unit price or price, and then set the item using the number keys 21. Operate the next item key 30. The clear key 24 is used to clear unit prices and prices that have been set by mistake.
The tare key 25 is used to set the tare weight on the electronic scale 1. When the tare weight is placed on the weighing plate 7 and the tare key 25 is operated, the display on the weight display section 10 becomes 0 and the net weight is set. The display section 13 lights up and the net amount of the product can be displayed on the weight display section 10 from now on. The tare preset key 26 is provided to preset the tare amount of a tare bag that is always used in the electronic scale 1, and to save the trouble of setting the tare amount using the tare key 26 each time a product is weighed. be.

In this embodiment, the customer key 27 can distinguish between four customers A, B, C, and D.
Customers can shop at any of the four scales that are connected to each other. In other words, for example, when customer A buys several items, even if he or she purchases each item using any electronic scale 1 among the electronic scales 1 ₁ to _{1 4} , the customer key A must be entered each time. When pressed, the total price up to that point is calculated, and the total price of the product is stored in a customer-specific memory (not shown) assigned to customer A of the electronic scale 1. Then, when you shop for the last item on any of the electronic scales 1 (for example, electronic scale 1 ₁ ) and press the customer specific key A and the total key 29, the contents of the memory assigned to customer A of each electronic scale 1 are displayed. (total price up to that point) is electronic scale 1 ₁
The total price is displayed on the price display section 12 of the electronic scale ₁₁ . At the same time, the printing device 5 issues a receipt 66 for this customer. The correction key 28 is used to correct a mistake in pressing the customer key 27.

As mentioned above, the preset data call key 31 is used to set the key 31 to the on position when calling up the unit price of a specific product preset in the totalizer 2 for each scale at the time of sale of that product. It is. By the way, the electronic scale 1 of this example
15 types of unit prices can be preset for each electronic scale 1, but if the scale designation dial 32 is set to a designated position on another electronic scale 1 other than the electronic scale 1, the preset price will be set for this designated electronic scale 1. The displayed unit price or price is transferred to the electronic scale 1. In this embodiment, since four electronic scales 1 ₁ to _{1 4} are used, each electronic scale 1
By presetting different unit prices for each product, one electronic scale 1 can call up up to 60 different preset unit prices for use when selling products.

When the day's settlement is to be made after the store has closed, the key switch 58 is set to the "Select" position, and the date of the day, the contents of the seven classification memories and the total memory are printed out in a journal.

In addition, in the description of the above embodiment, four electronic scales and printing devices can be connected to the totalizer, but the number of these electronic scales and printing devices is of course arbitrary. Furthermore, the types of unit prices or prices that can be preset are not limited to 15 types for each electronic scale, and the types can be increased or decreased as necessary. Further, although the tabulator is equipped with a journal, the printing function of the tabulator may be omitted if it is not necessary. Furthermore, instead of providing a plurality of printing devices for issuing receipts corresponding to customer keys, a plurality of printing devices may be provided corresponding to display scales, or,
Only one printing device may be provided and this printing device may be shared by a plurality of electronic scales. Alternatively, the product may be registered in the tabulator itself by using keys on the operation section of the tabulator.

"Effects of the Invention" As explained above, the present invention includes a plurality of electronic scales installed at various locations in a sales floor, and a system installed in each of the electronic scales for distinguishing product data including price data by customer. an input means for inputting attribute data; an operation means provided on each electronic scale for calling up the unit price of the product; and an operation means connected to the plurality of electronic scales for storing the unit price of the product in advance; When the operating means is called, the pre-stored product unit price data is transferred to the electronic scale, and when the input means is input, sales data corresponding to the products weighed by each electronic scale are aggregated for each customer. a control means for accumulating the price data for each customer and displaying the accumulated content on a display section of the electronic scale; and printing the sales data aggregated by the aggregation means for each customer and issuing a receipt. Since the present invention includes a printing means for issuing a receipt for each customer, and a printing command means provided in each of the electronic scales for instructing the issuance of a receipt for each customer, the following effects can be achieved.

Even if a customer weighs and purchases many types of products while visiting the sales floor, the current cumulative value can be immediately known using a nearby scale. As a result, payments can be made all at once at the final scale, which is extremely advantageous when selling face-to-face or shopping at a large market.

Since payments can be made in real time for each customer, receipts can be issued immediately at the end of the sale.

Since each scale uses common unit price data stored in advance in the aggregation means, it is possible to store a large amount of unit price data with the same storage capacity, compared to the case where the same unit price data is stored redundantly in each individual scale. becomes possible. Furthermore, there is no possibility of a situation where the unit prices used for the same product differ between the scales.

No matter which scale a customer purchases, they will receive a single customer-specific receipt detailing all purchases, including items purchased on other scales, starting from the time of the last item purchased. Can receive.

Each electronic scale is equipped with a printing instruction means that instructs the issuance of a receipt for each customer, so no matter which scale the customer used to purchase the last item, the store staff can print it on the same scale where the customer purchased the last item. The customer can issue a receipt with the details of the products he or she has purchased up to that point printed, eliminating the need for unnecessary travel.
