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 an input unit for inputting the unit price of, for example, 100 f. This unit price setting key consists of a numeric keypad that is often used on ordinary electronic desktop calculators.

Reference numeral 3 denotes a calculation unit that calculates the sales amount from the unit price signal input 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 enter the unit price 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, the sales Setting the unit price for degrees is complicated.

In view of these points, a structure has been proposed in which unit prices of frequently sold articles are stored in advance in 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, I
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 memory unit price from the specified address or to read out 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, but the unit price memory key I must have the same numeric keypad as the unit price setting key 2. , which becomes structurally complex and causes an increase in cost.

This invention was made in view of these points,
The gist is the unit price memory key T shown in Figure 2.
is omitted, and the unit price setting key 2 is used for the same purpose.

The configuration of the present invention, as shown in FIG. 3, omits the unit price storage key I, and instead associates the unit price setting key 2 with the unit price storage section 5.

To store a 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 a predetermined unit price to the storage section 5, and store the unit price in the storage section 5.
The user operates the address designation key 6 to designate which address of the system is to be introduced, and the unit price from the unit price setting key 2 is stored in the designated address.

At this time, the unit price from the unit price setting key 2 is also sent to the calculation section 3, but since there is no weight signal from the weight detection section 1, the calculation is not executed, and the article such as a case or a box is sent to the calculation section 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, the 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 section 5, turn the selection switch 8 to the unit price read side, and press the address designation key 6 to enter the address of the storage section 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 storing the unit price of the article is designated by operating the address designation key 6, and the sales amount at that time is calculated and displayed.

As is clear from the above description, the present invention is provided with a unit price setting key, an address specification key for specifying an address in the unit price storage section, and a selection switch for selecting a mode. The unit price is stored in each address of the unit price storage unit in advance, and when the selection switch is set to read mode and an address is specified using the address designation key, the amount is calculated based on the unit price stored at the address and the weight signal from the weight detection unit. It is possible to provide an electronic scale that is easy to operate and has good workability, without the need to set a unit price every time a measurement is made, as was the case in the past.

Claims (1)

[Scope of utility model registration request] In an electronic scale that calculates and displays refunds according to the weight detected by the weight detection section, a 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. an arithmetic unit that calculates the amount based on the calculation unit, an amount display unit that displays the calculation result of the arithmetic unit, a unit price storage unit that stores a plurality of unit prices input from the unit price setting keys, and a an addressing key for specifying an address;
It consists of a selection switch for selecting the mode of storing the unit price in the unit price storage section or reading out the unit price from the unit price storage section, and setting the selection switch to the unit price storage mode and operating the unit price setting key and the address designation key. As a result, the unit price set with the unit price setting key is stored at the address in the unit price storage section specified with the address specification key, and when the selection key is set to read mode and an address is specified with the address specification key, the corresponding unit price in the unit price storage section is stored. An electronic scale is characterized in that an arithmetic processing section calculates the amount (based on the unit price of the address and a weight signal from the weight detection section), and the result is displayed on the amount display section.
