<p>The invention provides a weight detecting device capable of improving detection accuracy by eliminating the influences of vibration disturbances from the device installation side and from the article mounting side. The weight detecting device comprises a weight detecting load cell (31) fixed at its fixed end (31a) to a fixing base (13) erected on a floor and having the weight of an article (X) applied to its free end (31b), a first vibration detecting load cell (32) disposed on the fixed end (31a) side of the weight detecting load cell (31) to detect a vibration component, i.e., a floor vibration component on the fixed end (31a) side, and a second vibration detecting load cell (33) disposed on the free end (31b) side of the weight detecting load cell (31) to detect a vibration component, i.e., a motor vibration component on the free end (31b) side. And the weight detecting device detects the weight of the article (X) with high accuracy on the basis of the detection signals from the load cells (31-33) by removing the vibration component from the detection signal from the weight detecting load cell (31).</p> |
