Abstract:
An electronic balance comprising: a load detecting mechanism which supports a weighing dish via a dish support, and which outputs a signal corresponding to a load on said weighing dish; and calculating means for calculating a value of the load on said weighing dish by using an output of said load detecting mechanism, whereinsaid dish support comprises four cantilever beams which respectively elongate in four directions in a horizontal plane, vicinities of tip ends of said cantilever beams respectively supporting corners of said weighing dish, and said electronic balance further comprises: deflection amount detecting means for individually detecting a deflection amount of each of said cantilever beams; and four-corner error correcting and calculating means for calculating a position of a center of gravity of the load on said weighing dish by using a result of the detection of deflection amounts of said cantilever beams, for, by using previously stored relationships between a position of a center of gravity of a load and a four-corner error, correcting the output of said load detecting mechanism, and for causing the corrected output to be used in the calculation of the value of the load by said calculating means.
