ABSTRACT:
In a multipoint scale for weighing a load applied to a placement section by a plurality of weight sensor units, the weight sensor unit includes a weight sensor having a strain-sensitive part; a first flexible elastic member for receiving the load applied to the placement section; a load transmission part for transmitting the load from the first flexible elastic member to a power point of the weight sensor; a load support part for supporting a fulcrum of the weight sensor; and a second flexible elastic member for receiving the load applied to the load support part and for maintaining a direction of the load applied to the strain-sensitive part of the weight sensor to be vertical in accordance with a deflection of the first flexible elastic member. Torsion of the weight sensor is avoided by reducing the effect of deflection of the placement section on transmission of the load to the weight sensor. Because the effect of the deflection of the placement section is reduced, a larger placement table can be used, and the placement table does not need to be a rigid body, enabling the use of a light-weight and inexpensive member or structure.
