Problems solved by technology

[0005] Such conventional weighing scales generally reset the zero point after pressing the measurement start switch (start button), and are in a state where the measurement cannot be started until the zero point update is completed. When the information is displayed, it cannot be loaded to the main body to start measurement immediately, which is inconvenient

Embodiment Construction

[0031] Hereinafter, an embodiment in which the weight measuring device of the present invention is applied to a so-called acceleration type scale with a body fat scale will be described with reference to the drawings. figure 1 It is a perspective view of a weighing scale 1 with a body fat scale in an embodiment, and FIG. 2 is figure 1 A block diagram of a scale with a body fat scale for , image 3 its about figure 1 A flow chart of the processing of the zero point update of the scale with a body fat scale. in addition, image 3 29, a storage unit 25, and a body weight measurement unit 47 arranged inside the main body 3 are shown in FIG. figure 1 Illustrations are omitted.

[0032] Such as figure 1 As shown, a weighing scale 1 with a body fat scale according to the embodiment (hereinafter referred to as weighing scale 1) has a body 3 formed in a nearly box-like shape, and a foot rest provided on the bottom surface (cover) side of the body 3 and supporting the body 3. (fee...

Abstract

The invention provides a weight measuring apparatus for assuredly performing zero-point reset through timing change according to then change of setting state and using environment, meanwhile realizing reduced power consumption. The weight measuring apparatus carries out zero-point reset as an output value of a load signal in an unloaded state when the weight measuring apparatus is not in use, including a weight measuring unit that measures a load applied to a machine body and outputs the load signals; and a control device that receives the load signals from the weight measuring unit at reset time intervals for carrying out the zero-point reset of the weight measuring unit in the unloaded state, in which the control device changes the reset time interval to next zero-point reset according to the difference between the output value of the load signal at the time of previous zero-point reset and the output value of the load signal at zero-point reset of this time.

Description

technical field [0001] The invention relates to a weight measuring device for measuring the weight of an object to be measured, in particular to a weight measuring device for updating the zero point when not in use. Background technique [0002] Conventionally, various weight measuring devices for measuring the weight of an object to be measured have been proposed, and in particular, a scale for measuring the weight of a person to be measured is used. A weighing scale as such a weight measuring device generally has a weight measuring part in the body, and a load cell having a deformable body (lifter) and a strain gauge (sensor) attached to the deformable body is used as the weight measuring part. Deformable bodies are formed by metal parts that deform according to the load when loaded. If the deformable object is deformed by the load when the subject is placed on the main body, the strain gauge expands and contracts accordingly, and the resistance change of the resistance v...
