Abstract: The invention provides a weight selecting apparatus capable of automatically performing calibration, and provides a weight selecting apparatus capable of certainly carrying objects to be inspected with a relatively simple mechanism and performing weight measurement of the objects. The objects, after being subjected to weight measurement by a first weighing unit 2, are sampled by a sampler 5, and those of the objects thus sampled are subjected to weight measurement by a second weighing unit 6. A calibration unit compares, for the same object, the measured result with that obtained by the first weighing unit 2 and discriminates whether or not a difference therebetween is within a specific error range, to perform calibration of the first weighing unit 2. Further, as a carrier 3 for carrying the objects to the weighing unit 2 one by one, there is used an intermittently rotatable carrying roller 32 having in its outer peripheral surface portion a plurality of carrying pockets 321.
