WEIGHING DEVICE

PROBLEM TO BE SOLVED: To absorb impact at a loading time, to stabilize early a weighing signal, and to prevent a damage of a sensor in the non-weighing state. SOLUTION: When a load is loaded, a load cell 2 is displaced corresponding to the load, while vibrating vertically, and generates a load signal showing the displacement. Piezoelectric bimorphs 16, 16 pressurize the load cell 2 in the frictional contact state therewith in the vertical direction with respect to the vertical vibration direction of the load cell 2 in the non-loading state. The frictional contact state of the piezoelectric bimorphs 16, 16 is removed at the point of delayed time from a load loading point of time on the load cell 2. COPYRIGHT: (C)2007,JPO&INPIT
