Hereinafter, with reference to FIG. 4, this digital weight t1(1)
Explain how it works. Note that the number at the beginning of the sentence corresponds to the processing number in FIG.

■ When the power is turned on, the power on L-ED (5a
) lights up, the Micro Combi Coater (/4) goes into measurement mode, and the display shows something like Figure 5 (A).
The mode selection switch (checks whether force is pressed or not. When the mode selection switch (force) is pressed, the mode shifts to a target weight setting mode of 0 or less, which will be described later.

■ If you step on the measuring platform unit (2) without pressing the mode selection switch, the weight of the person riding on it will be displayed.

■ The microcomputer CIA) uses the name key (9
) is checked to see if it is pressed. Name key (
If 9) is not pressed, the process returns to step (1) above, so processes (2) to (2) are performed in the same way as a normal digital weighing scale.

■ However, if you press any of the name keys (9), an operation is performed to subtract the target weight of the person specified by the name key (9) from the measured weight, and the resulting difference is displayed on the display. indicate. Figure 5 (b) is an example of the display, where 41 A I+ is specified with the name key (9), and the target weight of the person with A'' is '65.0 [kO]
This is an example of display when the measured weight is 70.2 [kg]. The difference is 5.2 [kO], which is heavier than the target weight, so 'o' (over) is displayed to the left of the difference display. On the other hand, Figure 5 (c) shows another example. This is an example of the display when the measured weight of 11 A 11 person is 61.4 [kO].Since it is lighter than the target weight of 65.0 [kG], the display of ++ 'l' (under) is the difference display. 3.6 [It is done to the left of kol.

Note that the initial value of the target weight is set to 0.0 (k(]), so if the target weight is not set, the measured weight will be displayed as is in the difference display.

■ If the 111th place selection switch (8) is pressed, the difference display is the above J: sea urchin kilogram display.

■ However, when the unit selection key (8) is pressed, the difference is converted into a calorie display and displayed. This is done by clamping 7 to the difference value in kG and setting the ψ position to Kcal. Figure 5 (d) shows the case where the calorie display is changed from the state shown in Figure 5 (b), and the display shows 36.4 [KCal], and it is "Sub" which means that the weight should be reduced.
is also displayed. Also, Figure 5 (E) is shown in Figure 5 (E).
If the calorie display (changed from the state of c) is 25.2
[K Cal] is displayed, and "Add" is also displayed to indicate that the amount should be increased.

(2) If the key switch (6) is not pressed, the process returns to (2) above.

■ However, if any of the key switches (6) is pressed. If the difference in calories is to be resolved within a predetermined weight adjustment period, for example 90 days, the calories to be eliminated per day, that is, the daily calories are calculated.

For example, in the case shown in FIG. 5(d), the daily calories are 404.4 [Cal]. In addition, in the case shown in Figure 5 (e), the daily calories are 280.0
[Cal].

■ If the adjusted calorie does not result in weight loss, proceed to the process ◎ described later.

■ If the adjusted calorie is weight loss, the calorie consumption per minute of the exercise subject corresponding to the pressed key switch (6) is set as the calorie consumption. The relationship between exercise subjects and calorie consumption per minute is set in advance inside the microcomputer, and the contents are as shown in the following table, for example.

7- Then, if you press JOG, F'' of the key switches (6), the calorie consumption is set to 9 [Cal].

0 The amount of exercise is calculated by dividing the daily calories obtained in the above (■) by the calories consumed in the above [phase], and the amount of exercise is displayed. For example, in the above ■, 404.4 [Cal]
is obtained, and if 9 [Cal]-〇- is obtained in the above ①, the momentum is obtained as 45 [min]. Therefore, as shown in Figure 5), the corresponding exercise subject “'JO
G, F" and the luck ljJ amount "45" are displayed.

Calories for the 01st day are displayed, and if you have lost meters, they are displayed along with your exercise amount. In other words, for example, '404,4°' is displayed with '45' as shown in Figure 5 (g).On the other hand, when there is no weight loss, '45' is displayed as shown in Figure 5 (g).
SPd” (Save per day) is displayed.

0 If the mode selection switch (force) is pressed during measurement mode, the target weight setting mode will be entered through process ①.

1. First, press the name key (9) of the person who is setting the target weight. During that time, only "H" (1-1ealth) in FIG. 5 (H) is displayed on the display □□□.

When any of the O name keys (9) is pressed, it is read. If you don't press it, it won't do anything. Note that when transitioning from the above O to this O, one of the name keys is always pressed.

The target weight corresponding to the pressed name key is read out from the memory of the microcomputer (example) and displayed. As shown in FIG. 5(H), the display (K) displays A'' indicating the name, H11 indicating the target weight, and the target weight, for example, 65.0 [kol].

9 =t=- When the switch (6) is activated, the target weight is set and stored accordingly. Key switch (
6) When pressing Δ, △ or Δ△, Δ or Δ
You must press one to three digits above the decimal point and one digit below the decimal point, such as ΔΔ, Δ. If the switch (6) is not pressed at all, the target weight is simply displayed and the setting is not changed.

O When the mode selection switch (with force) is pressed during the target weight setting mode, the mode is changed to the measurement mode, and the process moves to the above-mentioned process (2).

If the mode selection switch is not pressed, the process returns to process 0, so you can continue to set the target weight of another person.

Another example is one in which a period setting key switch is further provided so that the weight adjustment period can be set and changed as desired. Another example is an increase or decrease in spin interest.

(F) Effects of the Invention According to the digital weight scale of the present invention, it is possible to set a target weight arbitrarily, and the difference between the target weight and the actual weight is directly displayed digitally. You can accurately know the past. Therefore, it is ideal for health management purposes.
