PURPOSE: To make pulverulent body material feedable to a position of destination continuously and highly accurately, by scooping up the pulverulent body material inside an empty space made up of a bottom surface of a block and a groove on a mounting surface with a scraper of the block, while placing this material on a gas flow.

CONSTITUTION: Pulverulent body material 1 is stacked on a plane surface A provided with a groove (a), and a block 2, having a plane surface B covering a part of the groove (a), is made contact with the stacked material and slides in motion on the plane surface A. And, with a scraper 3 projecting over toward the groove (a) from the plane surface B locked to the block 2, the pulverulent body materials 1 inside an empty space surrounded by the plane surface B and the groove (a) is scooped up, and gas is fed in through passages (p) and (q) installed in the surface or the inside of the block 2. The pulverulent body material is set on a flow of this gas and conveyed to a position of destination from an outlet 6 of the passage (q) via a tube 8.
