<P>PROBLEM TO BE SOLVED: To provide a weight-measuring device capable of reliably carrying out zero-point reset according to a change in an installation state and environment of use, a change with time, or the like and reducing power consumption. <P>SOLUTION: The weight-measuring device carries out zero-point reset as an output value of a load signal in an unloaded state when the device is not in use. The device includes: a weight measuring part that measures a load applied to a body and outputs the load signals; and a control device that receives the load signals from the weight measuring part at reset time intervals for carrying out the zero-point reset of the weight measuring part in an unloaded state. 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. <P>COPYRIGHT: (C)2009,JPO&INPIT |
