Description

[Detailed Description of the Invention] The present invention relates to an electronic scale that electronically calculates and displays amounts according to weight.

With the recent development of digital technology, electronic scales that calculate and display amounts according to weight have appeared.

The configuration of this electronic scale is shown in Figure 1, where 1 is a weight detection unit that detects the weight of the sales item placed on the weighing pan, and 2 is a unit for inputting, for example, the unit price per 100 g. The unit price setting key is different from the numeric keypad that is often used on regular electronic desktop calculators.

Reference numeral 3 denotes a calculation unit that calculates the sales amount from the unit price signal input manually from the unit price setting key 2 and the weight signal from the weight detection unit 1. The calculation result of the calculation unit 3 is digitally displayed on the display unit 4. .

According to an electronic scale with such a configuration, it is necessary to input the unit by operating the unit price setting key 2 each time an article is sold, and if the unit price is a multi-digit and complicated combination of numbers, it is necessary to input the unit each time the item is sold. Setting the unit price is quite complicated.

In view of these points, a structure has been proposed in which the unit prices of frequently sold items are stored in advance in a memory.

Its configuration is shown in FIG. In FIG. 2, numeral 5 denotes a unit price storage unit, which has a plurality of addresses so that unit prices for several types of articles can be set.

6 is an address specification key for specifying the address, 7
8 is a unit price storage key for storing the unit price at the address specified by this designation key 6; This is a selection switch for selecting whether to read out the storage unit price from the specified address or the storage unit price from the specified address.

An electronic scale with such a configuration is advantageous because the unit price of frequently sold items is immediately introduced into the calculation unit 3;
The unit price memory key 7 must have the same numeric keypad as the unit price setting key 2, and the address designation key 6 for address designation is required.
This also makes the structure complex and increases costs.

This invention was made in view of these points,
The gist of this is the unit price memory key 7 shown in Figure 2.
Another advantage is that the address designation key 6 is omitted and the functions of the keys 6 and 7 are combined with the unit price setting key 2.

The configuration of the present invention, as shown in FIG.
is associated with the unit price storage section 5, and the selection switch 8 is provided with an address specification selection function in addition to the selection function of writing and reading from the storage section 5.

To store the unit price in the unit price storage section 5, turn the selection switch 8 to the unit price storage side, operate the unit price setting key 2 to send the desired unit price to the storage section 5, and input the unit price to any address in the storage section 5. The selection key 8 is moved to the address specification side again and the unit price setting key 2 is operated to specify whether to introduce the unit price, and the unit price from the unit price setting key 2 is stored in the specified address.

At this time, the unit price from the unit price setting key 2 is also sent to the calculation unit 3, but since there is no weight signal from the weight detection unit 1, the calculation is not executed, and even if some article is placed in the weight detection unit 1, the unit price is sent to the calculation unit 3. Even if the price is calculated according to the weight and displayed on the display section 4, there will be no problem in memorizing the unit price.

In this way, unit prices of frequently sold articles are stored in each address of the storage unit 5 in sequence.

Next, when reading out the unit price stored in the storage unit 5, turn the selection switch 8 to the unit price read side, and press the unit price setting key 2 again to enter the address of the storage unit 5 where the required unit price is stored.
The contents of the address are read out to the calculation unit, and the amount is calculated based on the weight signal detected by the weight detection unit 1 at that time and displayed on the display unit 4.

Also, when selling another article, the address where the unit price of that article is stored is specified by operating the unit price setting key 2, and the sales amount at that time is calculated and displayed.

As is clear from the above explanation, in the present invention, the unit price setting key is also used to store the unit price in the unit price storage section, and the unit price setting key is also used to specify the address of the storage section. It can be expected to be simpler, smaller, lighter, and more reliable, and will also greatly contribute to cost reduction.

Claims (1)

[Scope of utility model registration request] In an electronic scale that calculates and displays an amount according to the weight detected by the weight detection section, the weight detection section, a unit price setting key, a weight signal from the weight detection section and a unit price signal from the unit price setting key. It consists of a calculation section that calculates the amount based on the calculation section, an amount display section that displays the calculation result of the calculation section, and a unit price storage section that stores the unit price manually entered from the unit price setting key. When storing a predetermined unit price in the unit price storage section by operating the unit price, the address of the storage section is specified using the unit price setting key, and instead of operating the unit price setting key, the contents of this storage section are read out and the weight detection section An electronic scale characterized in that an amount is calculated in a calculating section based on a weight signal from the electronic scale.
