PURPOSE:To enable weighing at a high speed with high accuracy by connecting the top and bottom of a support to the stationary parts corresponding to respective positions by means of elastic members projecting horizontally to the fulcrum side and the opposite side thereof. CONSTITUTION:Lower thin leaf springs 13, 14 are mounted in accordance with the mounting parts of upper thin leaf springs 11, 12 between the horizontal mounting surface 6c in the lower part of a support 6 and the horizontal mounting plates 8c, 8d provided in the leg parts of opposed stands 8 on both sides thereof. When articles to be weighed are placed on a weighin pan 7, the load thereof acts on the weight point and a rod 2 tilts in proportion to the weight of the articles. The output proportional to the weight of the articles, that is, the inclination, is generated in a displacement detector 15 by said inclination, and the electric current proportional to said output is supplied to a force coil 16 which generates the force for pulling a core 16a downward. When the force thereof and the weight of the articles balance, the rod is balanced. The current flowing in the coil 16 in this stage is increased and the weight of the articles is calculated. |
