PROBLEM TO BE SOLVED: To provide a hygienic electronic gravimeter which can surely improve storageability by a simple structure. SOLUTION: In the electronic gravimeter, a first top plate 110 and a second top plate 120 can open in a single-plate-like open state and close in a closed state in which their lower surfaces face each other. When the first top plate 110 and the second top plate 120 are closed, load cell units 141 to 148 can be displaced by cell support mechanisms 125 to 128 to positions which do not interfere with each other. The size of a top plate member 101 in the plate thickness direction in the closed state can be thereby nearly the thickness obtained by adding the plate thickness of the top plate member 101 to the size in the open state. The occupying volume in the closed state can be thereby remarkably reduced, improving storageability surely. COPYRIGHT: (C)2009,JPO&INPIT
