項記載の電子天びん。[Claims for Utility Model Registration] (1) A dish supported by a movable column of a roberval mechanism in which a fixed column and a movable column are arranged at both ends of two mutually parallel elastic beams. In a balance that transmits an applied load to a load sensor via a lever connected to the movable column part by an elastic connection part, the roberval mechanism is formed integrally with each of the column parts and each beam part. The lever is formed by stacking a plurality of thin plates formed by stacking each other in a direction orthogonal to the axial direction of each of the pillar portions and each beam portion, and the lever is connected to at least the elastic connecting portion and the roberval mechanism. An electronic balance characterized in that it is integrally formed of a thin plate having the same coefficient of linear expansion as the thin plate forming the balance. (2) The electronic device according to claim 1 of the utility model registration claim, characterized in that at least one of the thin plates forming the roberval mechanism is integrally formed with the lever and the elastic connecting portion. Balance. (3) The electronic device according to claim 1 of the utility model registration claim, characterized in that a thin plate forming the lever and an elastic connecting portion is inserted and held between the thin plates forming the roberval mechanism. Balance. (4) Utility model registration claims 1, 2, or 3, characterized in that a spacer having the same linear expansion coefficient as each thin plate is interposed between each of the thin plates.
Electronic balance mentioned in section.
