Electronic balance

A scale comprising:

• a housing having a circumferential portion, and first and second side portions at both ends of the circumferential portion;
• and
• an electronic balance provided in the housing and comprising:
• a first Roberval's chain comprising:
• (1) a first fixed pillar fixed to the housing;
• (2) a plurality of first beams extending substantially in parallel with each other and in a first extending direction;
• and
• (3) a first movable pillar supported by said first fixed pillar via said plurality of first beams and configured to receive a load to be measured;
• a second Roberval's chain connected to the first Roberval's chain and comprising:
• (1) a second pillar fixed to the housing;
• (2) a plurality of second beams extending substantially in parallel with each other and in a second extending direction substantially perpendicular to the first extending direction of said plurality of first beams;
• and
• (3) a second movable pillar supported by said second fixed pillar via said plurality of second beams, said second movable pillar being connected to said first movable pillar;
• and
• a detector configured to detect the load electrically via a movement of said first movable pillar.
