To provide an apparatus for weighing an article at a plurality of specified positions which uses a plurality of weight detectors and eliminates the influence of internal forces in the horizontal direction due to bending, etc., of a positioning jig loaded on each weight detector through a knife edge with the article positioned on the jig, thereby measuring the weight more accurately.
At least one of blade bearings 30, 40 corresponding to weight detectors 1, 2 for receiving and transferring the weights of an article 10 and its positioning jig 5 to the detectors 1, 2 respectively through knife edges 3, 4 is supported with the detector 2 through a mechanism 41 for weakening the horizontal rigidity, compared with those in other directions, so that the bearing 40 moves horizontally to absorb internal forces enough to avoid having the effect on the weight detection result.
