Abstract

A weight scale includes weight measurement means, storage means for storing a weight measurement value along with a measurement day and time, determination means for determining whether a fluctuation range of the weight measurement value in the same day is within a predetermined reference range, and display means for displaying a percentage of days determined that the daily weight fluctuation is within the reference range. In this manner, a trend in weight change can be grasped even with the measurement of a relatively short period.

Claims

1. A weight scale comprising:

weight measurement means;

storage means for storing a weight measurement value along with measurement day and time;

determination means for determining whether a fluctuation range of the weight measurement value in the same day is within a predetermined reference range; and

display means for displaying a percentage of the days determined that a daily weight fluctuation is within the reference range in a predetermined period.

2. The weight scale according to claim 1, wherein the display means also displays change in weight in the predetermined period.

3. The weight scale according to claim 1, wherein the display means also displays an average value of the daily weight fluctuation value in the predetermined period.

4. The weight scale according to claim 1, wherein the display means displays in a graph a day-to-day daily weight fluctuation value in the predetermined period.

5. The weight scale according to claim 1, wherein the display means displays in animation the day-to-day daily weight fluctuation value in the predetermined period for every day.

6. The weight scale according to claim 1, being configured to diagnose a health state based on at least one of the average value of the daily weight fluctuation value and a deviation from the reference range of the daily fluctuation value in the predetermined period, and give a health guideline advice based on a diagnosis result.

7. The weight scale according to claim 1, further comprising:

body composition value measurement means for measuring a body composition value;

wherein

the display means performs a display to urge measurement by the body composition value measurement means when change in weight in the predetermined period is greater than a predetermined threshold value.

8. The weight scale according to claim 1, wherein the determination means determines that a fluctuation of a weight measurement value in morning or when waking up and a weight measurement value at night or before going to bed of the same day is within the reference range in a case of increase within the weight amount that decreases during sleep or healthy decrease within a desired range.
