The baffle 31 is provided with a round hole 311, and the diameter of the round hole 311 is larger than that of the material 8. When the circular hole 311 is concentric with the cross section of the leading-out hole 41, the leading-out hole 41 is opened, the material 8 in the counting groove 11 can flow out from the leading-out hole 41 by manually sliding the baffle 31, and when the circular hole 311 is staggered with the leading-out hole 41, the baffle shields the leading-out hole 41 to close the same. Each outlet hole 41 of the base is provided with a switch device 3 for opening and closing the outlet hole 41 to open or close each outlet hole 41.

The pressed portion of the flap 31 is sealed by a seal cover 33, and the seal cover 33 is elastically stretchable and contractible, so that the use of the flap 31 is not affected. The baffle 31 is isolated from the external space to reduce the entrance of air impurities or contaminants from the baffle 31 into the material counter and contaminate the material 8.
