Description

[Detailed Description of the Invention] This invention is a digital display that has an aggregation function that aggregates various data such as weight and price of each product sold, as well as a printing function that prints data for each customer and issues a receipt. Regarding scales.

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 a display.

By the way, in general stores, after closing, it is necessary to know various data such as the total sales for the day, the total sales by customer, and the total number of customers. For this reason, until now, for example, a cash register was installed separately from the electronic scale, and the weight, price, type, etc. of the product, which had been weighed and priced in advance using a digital display scale, were registered at the time of sale. I am trying to register it on the machine. Therefore, it is necessary to separately weigh each product using an electronic scale and to register various data such as the weight, price, type, etc. of these products in the cash register at the time of sale, which is time-consuming and time-consuming. It was on.

Furthermore, it is customary to issue a receipt 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.

This invention was made in view of the above circumstances,
The purpose of this is to connect multiple electronic scales to a tabulator, so that when the product is sold, the electronic scale weighs the product and calculates the price, while at the same time the tabulator can classify and tabulate various data. To provide a digital display weighing device having a printing device capable of performing classification and tabulation processing with easier operations, and issuing a receipt to a customer.

Hereinafter, one 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 the present invention. In this embodiment, four electronic scales (digital display scales) 1 (1 ₁ to 1 ₄ ) of the same type are connected to 3
A fourth electronic scale ₁₄ is connected to the totalizer 2 via a cable 4. In addition, four printing devices 5 (5 ₁ , 5 ₂ , 5 ₃ , 5
₄ ) are connected. 4 printing devices 5 ₁ to 5
₄ are respectively associated with customer keys A, B, C, and D provided in the four electronic scales ₁₁ to _14, respectively. As a result, as will be described later, data such as the weight and price of the products weighed by the electronic scales ₁₁ to ₁₄ are sent to and stored in the corresponding customer memory of the tally unit 2 via the cables 3 and 4. , the weight and unit price 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, D) of the electronic scale 1 where the customer made the last purchase and calculated the total price. , price, total price, date, etc. are printed on and a receipt 66 is issued.

Next, the configuration of the electronic scale 1 will be explained with reference to FIGS. 2 to 4. The electronic scale 1 is roughly divided into a display section 6, a weighing pan 7, an operation section 8, and an AD converter, an arithmetic circuit, a control circuit, a memory, a display control circuit, etc. stored inside the main body of the electronic scale 1. Ru. 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 unit 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 A by customer
(B, C, D) Display sections 17, 18, 19, and 20 are provided, respectively. The net weight display section 13 is lit when the product is being tared, the tare weight display section 14 is lit when the weight is negative (less than zero) or the tare weight is displayed, and the error display section 15 is lit. It 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 to 15, 17
-20, a light emitting diode is used as a display element. Further, in the classification display section 16, when the classification key 23 and number key 21 are operated in order to register the classification of the product in the tally unit 2 at the time of sale of the product, a number representing the classification is displayed on the classification display section 16, as will be described later. In this example, products can be categorized into up to seven categories,
For example, in the case of a product corresponding to category 3, the number "3" is displayed on the category display section 16.

Next, to explain the configuration of the operation section 8, number keys 2
1 is the numeric keypad for unit price setting "0", "1",...
It consists of "9" and the keys "X", ... "XV" with Roman numerals written on the key top. As will be described later, the electronic scale 1 of this embodiment stores the unit price of specific products (15 types) whose items and classifications are specified by operating keys on the operation section of the totalizer 2 in the memory of the totalizer 2. Alternatively, prices for items sold individually can be preset for each electronic scale.
And preset data call key 3 of electronic scale 1
After setting 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.), and the preset value will be displayed from the tabulator 2. Electronic scales are increasingly displaying the unit price of products. 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 mentioned above, the classification key 23 and the item key 30 are used to classify and register products by item in the memory for each classification and item in the tally unit 2. After setting the classification with the numerical keys 21, the classification key 23 is used.

Note that the date is also printed at this time. If you take out the printed journal, you can check the preset data mentioned above. If you wish to change some of the data that has been preset in this way, set the key switches 58 and 59 to the "DATE" or "PRESET IN" position, then press the scale number key 55, item key 54 as described above. , the classification key 53, and the numeric keypad 52 to change the preset data of the specific product that you wish to change. In this case, the key switch 59 is set to the position (PRESET IN), and if the manual print switch 57 is pressed at this time, only the changed data will be printed on the journal at the same time as registration, and the changed data can be confirmed.

After presetting the unit price as described above,
By turning on the power switch 31 of each of the electronic scales ₁₁ to ₁₄ and setting the key switch 58 to the "up" position, data can be registered in the totalizer 2 while selling products at the same time. Here, an example of the operation when customer A shops for three items will be explained. It is assumed that the first product is a product of the third category 3, and the unit price of this product is preset at the address corresponding to the key "3" of the numeric key 21 of the electronic scale ₁₁ . The second product is sold individually at a price of 300 yen, is not preset, and is a product of category 5 of the fifth item. The third product is a product in category 13 of 13 items and its unit price
It is assumed that 150 yen is not preset. First, when customer A buys the first product using the electronic scale ₁₂ , he sets the preset data call key 31 to the ON position in order to call up the preset unit price for the electronic scale ₁₁ from the totalizer 2. Also, the scale designation dial 32 is set to the "1" position. Then, the product is placed on the weighing pan 7 of the electronic scale ₁₂ , and the key "3" of the numeric keys 21 is pressed. At this time, the called unit price and the weighed weight are multiplied by the arithmetic circuit of the electronic scale ₁₂ to calculate the price, and the weight, unit price, and price are displayed on each display section 10, 11, and 12. Then, when you press the key ``A'' of each separate key 27, the number of weighing ``1'', weight, and price are output from the scales 1 _{and 2} .
₂₎ , the number of customers "1", the customer type "A", and the preset classification, unit price, and item data are sent to tabulator 2 for processing. and stored in 7 categories-specific memory, item-specific memory, total total memory, and other corresponding memories. The preset data recall key 31 must be returned to the OFF position after data has been recalled. Next, when customer A buys the second product using the electronic scale ₁₁ , he turns off the key 31, presses the single item key 22, and then presses the keys "3" and "0" on the number keys 21.
Press "0" and enter the price of 300 yen. Next, the user presses the ``5'' key on the numeric keys 21 and the item key 30 to input item 5, and also presses the ``5'' key on the numeric keys 21 and the classification key 23 to input category 5. Then, when key "A" of the customer-specific key 27 is pressed, each output data from the electronic scale ₁₁ is similarly sent and registered in each memory of the tally unit 2, and the total price up to that point is recorded in each memory of the totalizer _2. will be displayed. Next, give the third product to customer A.
Suppose that someone is shopping on the electronic scale ₁₄ and wants to find the total price of the shopping, turn off the key 31, place the item on the weighing plate 7, and press the numeric keys ``1'' and ``5'' to input the unit price of 150 yen. , "0" in sequence, the price will be calculated. In addition, the item key 30, classification key 23, and number key 21 are pressed to similarly input the item and classification. In addition, when the key ``A'' of the customer-specific key 27 and the total key 29 are pressed, the calculation circuit of the electronic scale ₁₄ displays the first item purchased earlier.
and the total price of the second product is summed with the price of the third product. The calculated total price is electronic scale 1 ₄
is displayed on the price display section 12, and at the same time the lamp 17
It is shown that the displayed price is the total price for customer A. Further, the output data from the electronic scale ₁₄ is registered in the totalizer 2 in the same manner as described above. Also, from the time the total key 29 is pressed, the contents of customer A's shopping stored in the electronic scale ₁₄ are transferred to the printing device 54, and the contents are transferred to the printing device ₅₄ , including the date, weight of each product, unit price, price, and total price. etc. are printed and a receipt 66 is issued.

If you want to check the data registered in the tabulator 2 during the sale of a product, set the key switch 58 to the "dot" position, and press the item key 54 and the classification key 5.
3. If you specify data by operating the numeric keypad 52, that data will be called up and displayed in each display section 4 of the display section 35.
Displayed from 0 to 45.

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 the above embodiment, four electronic scales and printing devices can be connected to the totalizer, but the number of 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, 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.

As explained in detail above, this invention includes a plurality of electronic scales that set the unit price of a product, measure its weight, calculate the price by multiplying the unit price and weight, and display this price digitally on the display. , a totalizer that is connected to these multiple electronic scales and totals the data for all sold products, and a printing device that prints the data output from the electronic scales and issues a receipt for each customer. By configuring a digital display weighing device, when selling products using an electronic scale, you can simultaneously classify and aggregate various data related to the day's sales with simple operations, and have the advantage of being able to issue receipts to customers. be.
