７．に’が回転可能に設けられている。The powder supply device of the present invention has a plate-shaped body which is inclined with respect to the net-shaped body 3 inside the container main body whose bottom part is the net-shaped body 3.
7. ' is rotatably provided.
網状体３は、通常の金網で良いが、板状体に多数の細孔

ある。The mesh body 3 may be an ordinary wire mesh, or may have a structure in which a large number of pores are provided in a plate-like body, and is arbitrary depending on the purpose.
網状体３の開孔の大きい（メソシュ）は、粉体の粒度、
必要供給精度等により適宜決定される。The size of the openings in the mesh body 3 is determined by the particle size of the powder,
It is determined as appropriate depending on the required supply accuracy, etc.
容器本体認は通常、円筒状とされ、粉体を必要量収容し

調節すれば良い。Inside the container body, there are plate-like bodies u and Ia near the net-like body 3.
' is provided at an angle with respect to the net-like body 3. The plate-shaped body v' is provided with a rotating shaft 6, and when this rotating shaft 6 rotates in a certain direction (in the direction of the arrow in the figure), the powder in the container is moved near the surface of the net 3. The liquid is made to flow, passed through a mesh, and supplied to a measuring container g provided below. The amount to be supplied can be determined by setting the weight, etc. on the plate 1 using the weighing machine 7, and adjusting the rotation of the plate-shaped body q' by manually or automatically stopping the rotation of the motor 2.
また、供給し初めに板状体＆、ｌＩ’の回転を早くして

The gap between the plate-like bodies G, RI' and the net-like body J (varies depending on the number of rotations, etc.). By adjusting these appropriately, the optimum supply amount is determined. In order to change the powder supply amount during use, Although it is possible to make the gaps between the plate-like bodies g, u' and the net-like body 3 and the angle of the plate-like body 9 mechanically changeable, these are usually fixed and the rotational speed is changed. The supply amount is changed by changing .
