Kind Code:
B2
Abstract:
A powder supply device includes a hopper accommodating powder, a cylindrical roller provided below the hopper and rotatable around a rotational axis, and a wall surface storing the powder in a space between the roller and the wall surface. The powder supply device moves the powder stored between the roller and the wall surface in a rotation direction of the roller and drops the powder by the roller rotating. A plurality of groove portions extending in an axial direction are formed in a peripheral surface of the roller. At least one of the groove portions is formed such that a capacity allowing the powder to be accommodated changes in the axial direction.
