BOTTOMING DETECTION WEIGHING SCALE AND METHOD OF CONTROLLING WEIGHING SCALE

摘要

A body weighing machine (100) is provided with a distance measuring sensor (30) at the central position (C) of a base plate unit (50). A CPU (10) measures the body weight of a human subject. The CPU (10) then drives the distance measuring sensor (30) to measure a distance (Dm) between the sensor and a floor surface and determines whether a minimum distance (D) between the base plate unit (50) and the floor surface is zero. The CPU (10) displays via a display unit (15) a message indicating that an error has occurred in a case in which the minimum distance (D) is zero, and otherwise displays the measured body weight on the display unit (15).
