Abstract
A quantitative discharge apparatus for powder material, comprising: a tubular body for storing powder material; and an elastic membrane having plural penetrating apertures, the membrane constituting a bottom of the tubular body. The elastic membrane is vibrated by applying a positive pulsating vibration air, and thereby discharging powder material stored in the tubular body from the penetrating apertures of the elastic membrane. The plural penetrating apertures of the elastic membrane are formed on the circumference of a circle, of which center is a specific point of the elastic membrane.
