った。Disadvantages of the prior art The conventional measuring device has the following disadvantages. Since the rotary vane feeder measures and discharges powder and granular material by rotating a rotating body having radial vanes, a rotary motor is used to control the rotation angle of an output shaft with high precision, which is an expensive motor. And the cost is high. Also, since the powder and granules were measured and discharged by the rotation of the rotating body having radial vanes,
The granules always stay (exist) between the vanes from the inlet to the outlet of the casing, and when changing the type of the granules to be measured (when the When weighing another type of granular material), it is necessary to discharge (clean) the granular material remaining in the rotary vane feeder, and there is a disadvantage that the operation is troublesome.

を簡単な構造とすることが出来る。According to the present invention, the following effects can be obtained by the above configuration. According to the first and second aspects of the present invention, unlike the related art, an expensive motor for rotating the rotating body having the radial vanes is not required, so that the cost can be reduced accordingly. Also, if you send out the powder in the weighing container,
Since the inside of the measuring container becomes empty, when replacing the type of the granular material to be measured, unlike the related art, there is no need to perform the trouble of discharging the residual granular material. When the through hole of the slide plate is overlapped with the outlet of the substrate and the outlet of the substrate is set to a negative pressure, air flows into the measuring container from the porous body at the bottom of the measuring container, and the particles in the measuring container are gasified. Can be carried out (transported) from the weighing container by the flow of the liquid, so that it can be suitably incorporated in a powder material transport system widely used at present. According to the third aspect of the invention, the measuring container having a variable internal capacity can have a simple structure.
