Abstract:
1. A rotary measuring device adapted to measure a weight of an object, the rotary measuring device comprising: a measuring unit including a load receiving portion configured and arranged to receive a load resulting from the object and a load detecting portion having a fixed end and a free end on which the load receiving portion is disposed; a rotational drive unit configured and arranged to rotate the measuring unit; a centrifugal force error calculating unit configured to calculate, on the basis of a first measured value outputted from the load detecting portion in a state where the measuring unit is rotating, an angular displacement value of the load detecting portion in the vicinity of the free end with respect to a horizontal plane; and a weight value calculating unit configured to calculate a weight value of the object on the basis of the angular displacement value and a second measured value outputted from the load detecting portion in a state where the load receiving portion is receiving the load resulting from the object.
