Abstract

PURPOSE:To display the increase/decrease difference of the body weight of a person to be measured in an easy-to-see and easy-to-understand state by displaying the increase /decrease difference as a level indicator by the increase/decrease display and graphic display of the body weight. CONSTITUTION:The person to be measured steps on a measurement board, a weight sensor part measures the person, and display elements 44-47 of a digital display means A display the current body weight measured value. Then, while the person to be measured is on the measurement board, the display of the current measured value is updated and when several measurement data are coincident, the measured value is registered as a determined value. Then, the increase/decrease difference be tween the current body weight measured determined value and last body weight mea sured value (body weight target value) is calculated and the current body weight measured determined value is displayed on the display elements 44-47 of the display means A until the person to be measured gets off the measurement board. Then, when the person to be measured gets off, the display elements 44-47 of an increase/ decrease display means B illuminate to display the state where the increase/decrease difference increases, does not vary, or decreases, and the display elements 48-53 of a graphic display means illuminate to display the value of the difference of increase/ decrease.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention stores the difference between the current weight measurement value and the previous weight measurement value of the subject and the difference between the current weight measurement value and the weight target value. This relates to a weight scale that displays the difference.

<Prior Art> As shown in Fig. 10.11, a conventional general digital display weight scale 11 includes an upper cabinet 12 which also serves as a measurement board for the person to be measured, a lower cabinet 13 having a weight sensor,
Display section 14, start switch 15.16.17.18
(The start switch 15 is the code No. 1 test subject's memory selection/power input switch; the start switch 16 is the code No. 2 test subject memory selection/power input switch; the start switch 17 is the hood number
The memory selection/power input switch and start switch 18 of the test subject in No. 3 are code No.

This is a switch for memory selection and power input for the person to be measured (No. 4). ) etc.

In the plan view of the display unit 14 in FIG. 11, reference numerals 19, 20, 21, and 22 are display elements such as LEDs and LCDs that indicate the code number of each subject. Also, 23.
24, 25, and 26 are LEs that digitally display weight differences, etc.
D, a display element such as an LCD, and these constitute a digital display means A that displays the current weight measurement value.

Also, 2 7, 28. 29 are LEDs that indicate weight increase/decrease,
A display element such as an LCD, which indicates whether the difference between the current weight measurement value and the previous weight measurement value (or the difference between the current weight measurement value and the weight target value), that is, the evaluation is increased, zero, or decreased. An increase/decrease display means B is configured to display the amount. Note that this means B also serves as the display elements 23, 24, 25, and 26 of the digital display means A.

A display example using the display section 14 will be described below.

Figure 11(a) shows that when the subject in hood No. 2 weighs himself (display elements 2 and 0 light up), the change in weight is "
11 (b) shows the code No.
When the weight of the person No. 2 was measured, there was no change in weight (the display element 28 was lit), indicating that the difference was O.Okg. FIG. 11(e) shows the code No.
When the subject No. 2 measured his/her weight, the increase/decrease in weight was "decrease" and the difference was 2.0 kg.

<Problem to be solved by the invention> As described above, conventional weight scales digitally display the difference in weight increase/decrease, but this time, digital display means A that displays the numerical value of the weight measurement value is used.
Since the numerical value of the difference between the current weight measurement value and the previous weight measurement value is displayed on the display elements 33, 34, 35, and 36, the display of "weight" and "difference" may become confusing. there were.

In particular, if the numbers were too small, they could not be seen.

On the other hand, as awareness of health management has increased, trends in body weight have become important, and it has become necessary to more strongly appeal to users about the difference in weight gain and loss.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a weight scale that can display differences in weight of a person to be measured in an easy-to-see and easy-to-understand manner.

The embodiment of the present invention has the above-mentioned configuration.To summarize, there is a digital display means A that digitally displays the current weight measurement value, the previous weight measurement value, and the weight target value, and the digital display means A that digitally displays the current weight measurement value and the previous weight measurement value. Display the difference or the difference between the current weight measurement value and the weight target value graphically (e.g., in the form of a bar graph)
and an increase/decrease display that displays whether the difference between the current weight measurement value and the previous weight measurement value or the difference between the current weight measurement value and the weight target value is an increase, zero, or decrease. The controller 30 includes means B and a microcomputer for controlling each of the means. The controller 30 has a function of storing the previous weight measurement value or weight target value and the current weight measurement final value, and digitally displays the current weight measurement final value while the person being measured stands on the measuring board of the scale. A function to be displayed on means A,
Graphic display means C calculates the difference in increase or decrease between the current weight measurement final value and the previous weight measurement value or weight target value, and displays this alternately with the current weight measurement final value while the person being measured gets off the measuring board of the scale. and a function of displaying on the increase/decrease display means B.

Next, the operation of the weight scale will be explained with reference to the chart 70 of the controller 30 in FIG. 4(,)(b). In this operation example, the current weight measurement value is the previous weight measurement value (a value registered and stored as a final value for each ID No.), but it may also be compared with a target weight value (input in advance). The ID No. here refers to the code No.

The main 70- of this flowchart is, for example, the code N
When the person to be measured (o, 1) inputs the start switch 15, power is input and the display element 4 that displays IDN00 is turned on.
0 lights up and its ID No.

Displays the previous weight measurement value, and automatically performs zero point adjustment during that time. When the zero point adjustment is completed, "mouth 0 mouth" is displayed. Thereafter, the person to be measured gets on the measurement board, and the weight is sensed by the weight sensor part 32, and the measurement is performed.

And display element 44°45.4 of digital display means A
6.47, the current weight measurement value is displayed, and while the subject is on the measuring board, the current weight measurement value is updated at approximately 0.5 second intervals, and the current weight measurement value is updated three times in a row. When the data match, the measured value is registered as a final value, and the difference in increase or decrease between the final weight measurement value of this time and the previous weight measurement value (or weight target value) is calculated, and until the subject gets off the measurement board, Digital display means A for the confirmed weight measurement value this time
is displayed on the display elements 44 to 47. Then, when the person to be measured gets off, the display elements 44 to 4 of the digital display means A
7 is turned off to leave the display blank, and after about 1 second,
The display elements 44 to 47 of the increase/decrease display means B indicate whether the increase, zero, or decrease, and the difference in increase or decrease is indicated by lighting the display elements 48 to 53 of the graphic display means C.

For example, in the case of kg, the difference in increase or decrease is 0.5
, 1, 1.5, etc., in steps of 0.5 width, so when the value of the increase/decrease difference is located in the middle, it will be displayed approximately.

Thereafter, the final weight measurement value is displayed on the digital display means A, and this final value display and increase/decrease difference display are alternately performed three times each. In order to prevent battery consumption, the power is automatically turned off after a certain period of time.

In the above, we explained the case where the increase/decrease difference is the current and previous measured value, but if the increase/decrease difference is the difference between the current measured value and the target value, the set button switch to input the target value, the set button switch to increase the set value, A capotan switch and a decreasing capotan switch for reducing the numerical value are provided.
