Document Type and Number:
Japanese Patent JP2020040005
Kind Code:
A
Abstract:
To suppress unevenness on a powder surface.SOLUTION: In a case where at least one of heights of powder surfaces just above a plurality of chambers is out of a control range, when a maximum value of the height of the powder surface exceeds an upper limit value in the control range, an air supply device is controlled so that pressure of air to be supplied to the chamber, in which the height of powder surface just above the chamber reaches the maximum value of the plurality of chambers, is reduced. In a case where at least one of the heights of powder surfaces just above the plurality of chambers is out of the control range, when a minimum value of the height of the powder surface is less than a lower limit value in the control range, the air supply device is controlled so that pressure of air to be supplied to the chamber, in which the height of powder surface just above the chamber, of the plurality of chambers increases.SELECTED DRAWING: Figure 4
