Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an electronic scale, particularly an electronic scale that can add data regarding products sold by weight and data regarding products sold at a fixed price.

[Prior art and its problems]

Some conventional electronic scales calculate the total weight by adding data related to weighed products, such as the weight, number, and price of the weighed items for each weighing, displaying the data on the display, and printing it out using a printer. However, among the large number of products, there are not only products sold by weight, but also products sold at fixed prices that do not require weighing. ), which was uneconomical and inconvenient.

As a technique for solving such inconveniences, Japanese Patent Application Laid-Open No. 53-37063 discloses an invention in which data related to products sold by weight and data related to products sold at fixed price are selectively switched manually and input into an adding means. ing. In other words, in the case of price data for a product sold at a fixed price, first turn on the non-weighed item key, then input the price using the number keys, and then turn on the addition key to see the input price. will be added. In addition, in the case of price data for a weighed product, turn off the non-weighed item key, then place the product on the weighing pan and enter its unit price using the number keys.The price will be calculated from the weight and unit price. , then turn on the addition key
Then, the calculated price is added.

However, in such a configuration, the non-weighed object key must be turned on and off depending on the sales form of the product, which not only makes the operation extremely troublesome, but also causes data that is difficult to trust due to incorrect operation. will be displayed.

For example, when you want to add the price of a product sold by weight, if you turn on the addition key without switching the non-weighed item key from ON to OFF, the value will be displayed instead of the price calculated from the weight and unit price. If the unit price is added, the same inconvenience will occur.

[Means for solving problems]

This idea was proposed in view of the above-mentioned conventional circumstances, and it is an electronic system that can add both data related to products sold by weight and data related to products sold at fixed price, and is easy to operate and does not cause errors or malfunctions. The purpose is to provide a scale.

This invention is constructed as follows to achieve the above object. That is, a measuring means detects and calculates data related to products sold by weight, a measuring means detects whether a product is being weighed by the weighing means, and a numeral means stores data related to products sold at a fixed price. , the adding means adds the data detected and calculated by the measuring means which detects that the measuring means is in progress, and the measuring means detects that the measuring means is in progress; and switching means for causing the adding means to add the data set by the number setting means when it is detected that the number is not the same.

〔Example〕

This will be explained in more detail below. The figure is a block diagram showing the outline of this invention.

The weighing means 1 includes a weight sensor such as a load cell, a weight calculation unit that calculates the true weight of the product by subtracting the tare weight from the weight detected by the weight sensor, and a weight calculation unit that calculates the true weight of the product by multiplying the true weight by the unit price. It consists of a price calculation unit that calculates the price of the product, and outputs the weight, price, etc. of the product. The measuring means 11 detects whether a product is placed on the weighing pan of the weighing means 1 based on the true weight input from the weighing means 1, and outputs a weighing signal _S1 . The number setting means 2 is designed to allow input of the price of a regular price product, etc. using a numeric keypad. Further, the switching means 3 has a function of switching between the output of the measuring means 1 and the output of the numeral means 2 using the measuring signal _S1 as a control signal. That is, when nothing is placed on the weighing pan of the weighing means 1, the output of the weighing means 1 is zero or negative, and the weighing signal _S1 output from the weighing detecting means 11 is OFF, Since this is a time when weighing and selling is not being carried out, the signal output from the measuring means 1 is blocked, and only the output from the numeral means 2 is passed through and input to the adding means 4. Conversely, when a product is placed on the weighing pan and the weighing signal _S1 is ON, the output from the weighing means 1 is passed through and input to the addition means 4, and the output from the numeral means 2 is blocked. It's becoming like that. The output from the switching means 3 is input to the addition means 4, as well as the output from the multiplication means 6, which will be described later, and data input from at least one of them is added by pressing the addition key 41. It's becoming like that. The result of this addition is output to the printer 5 and printed, and is also input to the display 51.

The multiplication means 6 is used to omit multiple key operations when a plurality of same values are to be input into the number setting means 2, for example, when a plurality of products sold at a fixed price are sold. That is, in such a case, inputting the list price into the number setting means 2 and pressing the addition key 41 are necessary.
The ON operation may be repeated a number of times equal to the number of units sold, but after inputting the list price of the product using the numeric keys of the number setting means 2, and then pressing the multiplication key 61, the number of units of the item can be entered using the numeric keys mentioned above. By inputting the desired value, the multiplication means 6 can obtain the desired value. Then, the flip-flop 62 is set by turning on the multiplication key 61, and in this state is reset by turning on the addition key 41, and using the fall of the output at this time,
The data from the multiplication means 6 is input to the addition means 4. As a result, the data obtained by the multiplication means 6 and the data already input to the addition means 4 are added.

The operation of the electronic scale of the present invention having the above configuration will be explained according to the usage procedure.

First, when weighing a product to be sold by weight using this electronic scale, the weighing signal S ₁ is turned ON, the switching means 3 is turned ON, and the measuring means 1 side is turned ON, and the price data S ₂ regarding the product to be sold by weight is turned ON. is input to the adding means 4. In addition, when not weighing, the weighing signal S ₁ is
OFF, the switching means 3 automatically turns ON the number setting means 2, and data _S3 such as the price of the product sold at the regular price is input to the addition means 4. Then, when the addition key 41 is pressed, the addition means 4 sequentially adds the input data S ₂ or data S ₃ , and the addition result is printed by the printer 5 and displayed on the display 51 .

In addition, when adding data related to multiple regular price sales products, as described above, use the multiplication key 6.
1 and the numeric keypad to calculate the total price of the plurality of regular price sales products using the multiplication means 6, and further,
By turning on the addition key 41, the total price may be input to the addition means 4 and added to the already input value. The procedure in this case is a very natural procedure when selling a product sold at a fixed price, and there is no possibility of erroneous operations such as proceeding with the process without operating any key or any associated malfunctions.

[Effect of idea]

As explained above, this invention automatically switches between data related to products sold by weight and data related to products sold at fixed price using a switching means that uses a measuring signal, and data that is input to the addition means using an addition key. Since the data can be sequentially added, the data regarding the products sold by weight and the data related to the products sold at regular price can be added with one electronic scale without requiring any troublesome operations.
