Abstract

PURPOSE:To grasp exactly transition of the weight, etc., and to improve the function of a weight meter by providing a means for storing a measured value of the weight, and a means for displaying the measured value of the weight, which is read out of the storage means, in a form of a transition graph. CONSTITUTION:A weight sensor 1 is constituted so as to be interlocked with a measuring base 6, and for instance, in accordance with a load applied to the measuring base 6, an interval of two pieces of electrode plates is varied, and by the variation of its electrostatic capacity, the load is detected. A RAM 2 stores a measured weight data, and outputs a past weight data to a controller 5 in accordance with necessity. The controller 5 controls the whole operation of each part in accordance with the operation of a switch part 3 by a user, receives and displays 4 a weight data signal from the weight sensor 1, writes it in the RAM 2, reads out the past weight data which is stored in the RAM 2 and brings it to a graphic display on the display part 4, selects the maximum value and the minimum value from these data, or calculates the average value and displays 4 it.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electronic weight scale having a function of displaying changes in body weight.

<Conventional technology and problems> There are mechanical and electronic scales that have been used in the past, but both only display the weight at the time of measurement, and do not display changes in weight. .

Therefore, weight changes, which are meaningful as data for determining health conditions, cannot be determined by relying on the user's memory, and are insufficient to be useful for health management.

<Means for solving the problem> The present invention focuses on this point and is designed to display changes in weight. and display means for displaying the measured values in the form of a weight transition graph.

<Function> The electronic weighing scale of the present invention not only displays the weight at the time of measurement, but also displays past weight changes in a graph on the display means, which provides important data for health management. Provided in a visible form.

<Example> The illustrated embodiment will be described below.

Figure 1 is a block diagram, Figure 2 is a perspective view, 1 is a weight sensor, 2 is a RAM, 3 is a switch section, 4 is a display section, 5
is a controller, and 6 is a measurement stand.

The weight sensor 1 is configured to operate in conjunction with the measuring table 6. For example, the distance between two electrode plates changes depending on the load applied to the measuring table 6, and the load is controlled by changing the capacitance. Conventionally used detection means, such as a capacitive detection method, can be appropriately employed.

The RAM 2 stores measured weight data and outputs stored past weight data to the controller 5 as needed.

The switch section 3 is operated by the user to give various commands to the controller 5, such as a power switch,
Switch to change display content, press R to change weight data
A switch and the like for writing to AM2 are provided.

The display section 4 performs display in response to signals from the controller 5, and the display contents include, for example, a graphic display of the current weight and the weight from the past to the present, as well as the weight at a specific time in the past and the current weight. , maximum value, minimum value, average value, etc. from the past to the present.

Note that a small printer can also be provided as the display means.

The controller 5 controls the entire operation of each part described above according to the user's operation of the switch part 3, and receives the weight data signal from the weight sensor 1 and displays it on the display part 4, and also controls the RAM 2. or write to RA
The past weight data stored in M2 is read out and displayed graphically on the display section 4, the maximum value and minimum value are selected from these data, or the average value is calculated and displayed on the display section 4. .

Such various controls can be performed by storing a control program in advance in a ROM or the like built into the controller 5, for example.

FIG. 3 shows an enlarged example of the configuration of the switch section 3 and an example of the display of the display section 4. As shown in FIG. The switch unit 3 is a ten-key keyboard equipped with a function key 3a and numeric keys 3b for instructing various operations as described above.

Further, the display section 4 is provided with a graphic display section 4a that shows changes in weight, as well as a digital display section 4b that displays various data as described above.

The types of these displays depend on the content of the control program of the controller 5, and the circuit that can store past weight data depends on the capacity of the RAM 2.

If there are multiple users, assign a code number to each user and input this code number using the numeric keys 3b so that measurement and display can be performed for each user. good.

rcODE3J in the digital display section 4b in the figure indicates that the display for the user whose code number is 3 is being performed.

<Effects of the Invention> As is clear from the description of the embodiments above, the electronic weighing scale of the present invention displays weight changes in the form of a graph, allowing the user to monitor weight changes and trends of increase and decrease. The scale's functionality as a health management device has been greatly improved by providing accurate information, making it even more useful for health management.
