Description

[Detailed explanation of the idea] This invention relates to electronic scales.

Generally, it has a price display section, a weight display section, and a unit price display section, and the price is calculated based on a preset unit price by measuring the weight of the item, and the price, weight, and unit price are displayed on each of the above display sections. In electronic scales, the unit price for the item to be weighed is set in advance, and at the same time, data such as the code number of the item is input.

When weighing an item, the price, weight, and unit price are displayed on the price display section, weight display section, and unit price display section as described above, and if the electronic scale is linked with a label printer, The data displayed on the display and the data set in advance on the electronic scale, such as the code number, are printed on the label.

However, the electronic scales described above can only display three types of data on the display: price, weight, and unit price, so other than these three data, data such as the code number entered into the electronic scale cannot be displayed on the display. There was an inconvenience that I was unable to confirm.

This idea was developed in view of the above-mentioned drawbacks of the conventional methods, and when not weighing,
This invention provides an electronic scale that displays other data set on the electronic scale in addition to price, weight, and unit price on the price display section, which always displays only zero. The following is a description of the embodiment shown in FIG.

In FIG. 1, 1 is a numeric keypad used when setting a unit price, and 2 is a code key used when transferring data in a unit price register 3, which will be described later, to a code register 7, which will also be described later. 3 is a unit price register for storing the unit price set using the numeric keypad 1, and 4 is a weight register for storing the weight of the object to be weighed by a weight detecting section (not shown). 5 is a price register that stores the price calculated by the price calculation unit 6 based on the data stored in the unit price register 3 and weight register 4; 7 is a code register that stores the code number transferred from the unit price register 3; be. 8 is a price display section for displaying data stored in the price register 5 or code register 7; 9 is a unit price display section for displaying data stored in the unit price register 3; 10 is data stored in the weight register 4. This is a weight display section for displaying weight. Reference numerals 11, 12, and 13 are drive circuits for controlling the display sections 8, 9, and 10. A first AND circuit 14 matches the output from the unit price register 3 and the code key 2, and its output is connected to the code register 7. Reference numeral 15 denotes a delay circuit that operates based on the output from the first AND circuit 14, and this delay circuit sends a clear signal to the unit price register 3 after a predetermined time has elapsed after the signal is output from the first AND circuit 14. This outputs the following. 16 is a weight discrimination circuit that discriminates the data stored in the weight register 4;
The weight discrimination circuit 16 is configured to output an H level signal when the data in the weight register 4 is zero or negative, and output an L level signal when the data is positive. 17 is a second register interposed between the price register 5 and the price display section 8;
This second AND circuit 17 is an AND circuit, and one input terminal of the second AND circuit 17 is connected to the price register, and the other input terminal is connected to the weight discrimination circuit 16 via an inverter 18. 19 is code register 7
and the third AND interposed between the price display section 8 and the price display section 8.
One input terminal of this third AND circuit 19 is connected to the code register 7, and the other input terminal is connected to the weight discrimination circuit 16.
When the weight discrimination circuit 16 outputs an H level signal, the third AND circuit 19 becomes active, the data in the code register 7 is displayed on the price display section, and the weight discrimination circuit 16 outputs an L level signal. When the signal is output, the second AND circuit 17 becomes active, and the data in the price register 5 is displayed on the price display section.

In addition, the weight discrimination circuit 16 and the second and third
By the action of the AND circuits 17 and 19, when the data in the price register 5 and the data in the code register 7 are switched and displayed on the price display section 8, for example, as shown in FIG. 2, five digits and a code number are displayed on the price display. If two digits are used for the display, the code NO from the code register 7 should be wired so that it is displayed in the upper two digits of the price display section 8, so that the code NO display and the price display can be easily distinguished. Let's do it like this. Further, when displaying the code NO, an LED provided at a predetermined position of the price display section 8 is lit.

Also, the code No. to be input into the code register 7
is set to a product name stamp that is linked to an electronic scale, as shown by the broken line in Figure 1, the code NO data from the product name stamp is input directly to the code register 7 via the OR circuit 20, and the The price may be displayed on the price display section 8.

Next, the operation of the electronic scale according to this invention is shown in Figure 3a.
The explanation will be given according to the steps from f to f.

First, when the power switch is turned on, the weight display section 10 displays O, and the unit price display section 9 displays the data in the unit price register 3, as shown in FIG. 3a. In addition, since weighing is not being performed in this state, the data in the weight register 4 is zero or negative, and the output of the weight discrimination circuit 16 is at H level, so the price display section 8 displays the data in the code register 7. The LED lights up at the same time as the display.

In this state, to input a predetermined code NO into the electronic scale, first, if the previous data is stored in the unit price register 3, clear that data, and then operate the numeric keypad 1 to enter the code you want to input.
Type NO. Then, the code NO entered using the numeric keypad 1 is first displayed on the unit price display section 9, as shown in FIG. 3b.

Next, if the code number displayed on the unit price display section 9 is correct, the code key 2 is pressed. Then, the first AND circuit 14 matches the output of the unit price register 3 and the output of the code key 2, transfers the data in the unit price register 3 to the code register 7, and the price display section 8 displays the data as shown in FIG. 3c. Like, code register 7
Displays the code number transferred to. At this time, the code NO is displayed in the upper digit of the price display section 8, and the data in the unit price register 3 is
It is automatically cleared by a clear signal output from the delay circuit 15 connected to the AND circuit 14, and O is displayed on the unit price display section.

In this way code register 7 of code NO.
When the input is completed, next operate the numeric keypad 1 to input the unit price corresponding to the code No. just entered into the unit price register 3. Then, the unit price that has just been input is displayed on the unit price display section 9, as shown in FIG. 3d, and the weighing preparation is completed.

After the preparation for weighing is completed as described above, when the object to be weighed is placed on the weighing section of the electronic scale, the weight register 4 stores the weighing data at that time, and the value is as shown in Fig. 3e. The weight is displayed on the weight display section 10. Also, when the data in the weight register 4 becomes positive, the output of the weight discrimination circuit 16 goes to L level, so the price display section 8 uses the price calculation section 6 based on the data in the unit price register 3 and the weight register 4. The calculated price stored in the price register 5 is displayed. At this time, the LED will turn off.

When the weighing operation is completed and the object to be weighed is removed from the weighing section, the data in the weight register 4 becomes zero or negative again, and as shown in FIG. The set code number and unit price are displayed on the unit price display section 9, respectively.

In the above explanation, the code NO is displayed on the price display section 8 when no measurements are taken. However, when no measurements are taken, the price display section 8 displays not only the code NO.
It is also possible to display data such as the effective date or processing date of the product to be weighed.

As explained above, this idea is based on the price display section,
An electronic scale that has a weight display section and a unit price display section, measures the weight of the object to be weighed, calculates the price based on a preset unit price, and displays the price, weight, and unit price on each of the display sections. When inputting data such as code number, processing date, etc. in addition to the above three data of price, weight, and unit price at non-weighing time, display the data on a display other than the price display section, and then display the data. Since the data is transferred to the price display section and displayed by key operation, data such as code number and processing date can be checked each time the weighing is completed. At the same time, when inputting data such as code number and processing date, the data is confirmed in the unit price display section and then transferred to the price display section, so it is possible to prevent input errors when inputting data.

Furthermore, in the electronic scale according to this invention, when data other than price is displayed on the price display section, that data is displayed in the upper digits of the price display section.
Easily distinguishable from price display.
