Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight scale having various measurement modes.

[0002]

2. Description of the Related Art Conventionally, there have been various types of scales for measuring weight, such as a dedicated scale for measuring weight only and a scale for measuring weight and body fat.

[0003]

However, in these devices, the measurement mode to be measured is specified for each device, and the measurement mode cannot be switched depending on the application. For this reason, when measuring body weight in a group health checkup, a dedicated machine for measuring body weight was used, and when measuring body weight and body fat, a scale with body fat meter was used. Also, when the BMI measurement is required in a group health checkup recently, the measured data is input to a computer at a later date to calculate the BMI and output it to a health checkup report.

Provide.

FIG. 3 is a schematic electric circuit diagram of the weighing scale 1. An arithmetic processing unit 10 comprising a microcomputer is provided, and a known digital weighing unit 2, an input unit 8, and a display unit 9 are connected. Storage unit 1 for microcomputer
3 are connected. A power supply unit 14 that supplies power from commercial power is connected to the arithmetic processing unit 10 via a power switch 19. FIG. 4 is a flowchart showing the same procedure on the left side of the scale 1, FIG. 5 is a diagram showing a display state in the body fat percentage measurement mode, FIG. 6 is a diagram showing a display state in the body weight / BMI measurement mode, FIG. 7 is a diagram showing a display state in the weight measurement mode.

Next, the operation of the weight scale 1 will be described with reference to FIGS. First, when the power switch 19 of the weighing scale 1 is pressed (step S1), the microcomputer is initialized (step S2), and the numerical value display unit indicating the numerical values of the weight and the height blinks for several seconds. If the set key 15 is pressed in this state, it is determined as Yes in step S3, and step S1
The process proceeds to step S7, but if the set key 15 is not pressed, the process proceeds to step S
The process proceeds to the body weight / body fat percentage measurement mode after 4. Step S
4 is the ON / OFF of the weight unit switching key 18 for switching the weight unit.
Judgment of off, if not on pounds (lb)
Is turned on, kg is set as a unit of the weight scale 1 (steps S5 and S6). With this setting, the display unit 9
In the portion that displays the unit of weight, either kg or lb is displayed, and the unit of length is also cm (centimeter) or ft.
One of -inch (feet-inch) is displayed. In this description, since kg is set, cm is set as a unit of length corresponding to this kg. In step S7, gender and athlete settings are made.
By pressing the up key 16 and the down key 17, four types of male (MALE), female (FEMALE), male athlete, and female athlete are selected, and the selection is confirmed by pressing the set key 15. At this time, when a male athlete and a female athlete are selected, a mark of either male or female and an athlete's mark are displayed at the same time. FIG. 5A shows a display when a man is selected. Next, when the age is input in step S8, the mark indicating the age (AGE) on the display section 9 is lit, and the initial value 25 is displayed in the portion where the numerical value of the age is displayed. By pressing the key 17 to match the numerical value to the age of the measurer (FIG. 5 (b)), by pressing the set key 15, this age is determined,
Proceed to step S9. In step S9, first, the display unit 9
A mark indicating the height (HEIGHT) is illuminated, cm, which is a unit of length, is displayed, and an initial height of 150 is displayed. The value of 150 is depressed by pressing the up key 16 or the down key 17, as shown in FIG. 5C, to the height of the measurer, for example, 170 cm, and the set key 15 is depressed. When determined, step S1
Then, as shown in FIG. 5D, the weight unit of the display unit 9 is set to kg, and the weight value is set to 0.0. Then, the operator turns on the STEP ON mark on the display unit 9 so as to prompt the user to measure on the upper surface 3 of the weight scale 1. Then, when the measurer gets on the upper surface 3, the weight is measured by the scale unit 2, and the data is sent to the arithmetic processing unit 10 and displayed on the display unit 9. Next, at step S11, the electric impedance of the measurer is measured. At this time, a mark indicating the fat percentage (FAT%) is lit on the display unit 9 as shown in FIG. From 11, a constant current of a predetermined frequency flows between one pair of left and right foot electrodes 6 and 7, and a voltage measurement is measured between the other pair of foot electrodes 6 and 7,
The impedance is calculated by the calculation processing unit 10, and the body fat percentage of the measurer is calculated from a known calculation formula. The result is displayed in step S13 as shown in FIG. 5 (f). In this display, gender, age, weight, and body fat percentage are displayed. This display is, for example, 3 in step S14.
If a timer of 0 second is set and no key other than the power switch 19 is pressed in step S15, the timer continues in step S16 until the timer times out. When another key is pressed in step S15 or 30 seconds elapse and the timer times out, the process returns to step S7, and the weight and body fat percentage of another person can be measured.

Next, when the set key 15 is turned on in step S3, it is determined in step S17 whether or not the set key 15 is turned on again.
26, if it is turned on, a mark indicating the weight (WEIGHT) is turned on and the numerical value of the weight is set to 0.0 as shown in FIG. The process proceeds to S18 and thereafter. Step S18
In step S9, the height (HEIGHT) is displayed and the height of the measurer is input as shown in FIG. In step S19, as shown in FIG. 6C, first, the BMI mark is turned on, the weight unit is displayed, and the numerical value of the weight is set to 0.0. Further, the BMI value display portion is set to 0.0, and the STEP ON mark on the display unit 9 is also lit to urge the measurer to ride on the upper surface 3 of the weighing scale 1. Then, in step S20, the data from the scale unit 2 is processed, and the BMI is calculated. In step S21, the values of the weight and the BMI are displayed as shown in FIG. 6D. In steps S22 to S24, steps S4 to S6
Switch weight units as before. Then step S2
If the set key 15 is not turned on in step S5, step S1
9, the measurement of the body weight and BMI of the same subject is repeated. If the set key 15 is turned on in step S25, the process returns to step S17.

If the set key 15 is not turned on in step S17, the weight (WEIGHT MODE) mark is turned on in step S26 as shown in FIG. The STEP ON mark on the display screen is also turned on to urge the measurer to get on the upper surface 3 of the weighing scale 1 for measurement. When the measurer rides on the upper surface 3, the weight is measured by the scale unit 2, and the data is sent to the arithmetic processing unit 10, and in FIG.
It is displayed as shown in FIG. The step of switching the weight unit from step S28 to step S30 is performed in step S4.
Since this is the same as step S6, the description is omitted. After steps S29 and S30, the process returns to step S17.

After turning on the power switch 19, the weight scale 1 is turned off from the commercial power supply,
The operation continues unless the power switch 19 is turned on again.
When the power is on, the power can be turned off by pressing the power switch 19 at any time. In the present embodiment, the body fat percentage is calculated and displayed for the body fat, but the body fat amount may be calculated and displayed.
