Abstract:
1. A biometric apparatus which carries out zero-point reset as an output of a load signal in an unloaded state when the biometric apparatus is not in use, the biometric apparatus comprising: a weight measuring unit having a predetermined zero-point for measuring a load applied to a body of the biometric apparatus and outputting a load signal which indicates the load; an inclination sensor for measuring an inclination angle of the biometric apparatus with respect to the horizontal plane and outputting a signal indicative of the measured inclination angle; and a control unit connected to the weight measuring unit and the inclination sensor for determining whether or not the measured inclination angle is within a predetermined angle range with respect to the horizontal plane on the basis of the signal at predetermined intervals and whether or not the load signal is stabilized when the biometric apparatus is not in use, wherein the zero-point reset for resetting the output of the load signal from the weight measuring unit to the zero-point instead of the predetermined zero-point is carried out by the control unit when the control unit determines that the measured inclination angle is within a predetermined angle range with respect to the horizontal plane and the load signal from the weight measuring unit is stable, and the zero-point reset is not carried out by the control unit when the control unit determines that the measured inclination angle is not within the predetermined angle range with respect to the horizontal plane.
