Abstract
A control method for discharging particles and an apparatus executing the method are disclosed. The control method includes steps of passing particles through a particles-supplying path connected to a supplying section of the particles at one end of it, and having a delivery opening for discharging the particles at the other end of it and controlling to form a cover consisting of at least a part of the particles by changing a density of at least a part of the particles existing in the particles-supplying path so as not to discharge the particles from the delivery opening. The apparatus includes a particles-supplying path connected to a supplying section of particles at one end of it, and having a delivery opening for discharging the particles at the other end of it and a passage controller for forming a cover consisting of at least a part of the particles by changing a density of at least a part of the particles existing in the particles-supplying path so as not to discharge the particles from the delivery opening.
