Abstract
This invention provides a method of weighing powder/chip, in which the powder/chip can be fed from the conduit into the weighing vessel accurately and efficiently without being affected by the state of the conduit, that of the weighing vessel and that of ambient air. With the method, the powder/chip is weighed by means of the conduit arranged below a storage section and adapted to be tilted around a pivot according to a command sent from a weighing section to let the powder/chip fall through a discharge port at an end of the conduit into a weighing vessel placed on the weighing section. The conduit is tilted sequentially at least by three different feeding angles from large, small to minute to let the powder/chip fall by a large volume, a small volume and a minute volume respectively.
