Abstract

A powder supply device includes: a storage unit that stores a mixed agent including a functional material-containing powder and magnetic powder, the storage unit being provided with a discharge port through which a part of the stored mixed agent is discharged; a supply unit that holds the mixed agent and supplies the functional material-containing powder from the storage unit; and a magnetic body that covers at least a part of the discharge port and forms a nap of the mixed agent to prevent the mixed agent that is dispersed in air from flowing out through the discharge port.

Claims (29)

1. A powder supply device comprising:

a storage unit that stores a mixed agent including a functional material-containing powder and magnetic powder, the storage unit being provided with a discharge port through which a part of the stored mixed agent is discharged;

a supply unit that holds the mixed agent and supplies the functional material-containing powder from the storage unit; and

a magnetic body that covers at least a part of the discharge port and forms a nap of the mixed agent to prevent the mixed agent that is dispersed in air from flowing out through the discharge port.

2. The powder supply device according to claim 1 , wherein the discharge port is an opening provided on a bottom surface of a first end portion that is one end portion of the storage unit, the opening being opened downward.

3. The powder supply device according to claim 2 , wherein the discharge port is a circular opening.

4. The powder supply device according to claim 3 , wherein

the magnetic body has an S pole and an N pole that are magnetized so as to be arranged in a direction in which a bottom surface of the storage unit extends.

5. The powder supply device according to claim 4 , wherein the S pole and the N pole of the magnetic body extend along a line connecting both end portions of the storage unit.

6. The powder supply device according to claim 5 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects the line connecting both the end portions of the storage unit.

7. The powder supply device according to claim 4 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects a line connecting both end portions of the storage unit.

8. The powder supply device according to claim 4 , wherein the magnetic body is a magnetic body in which a plurality of the S poles and a plurality of the N poles are arranged in parallel at equal intervals.

9. The powder supply device according to claim 2 , wherein

the magnetic body has an S pole and an N pole that are magnetized so as to be arranged in a direction in which a bottom surface of the storage unit extends.

10. The powder supply device according to claim 9 , wherein the S pole and the N pole of the magnetic body extend along a line connecting both end portions of the storage unit.

11. The powder supply device according to claim 10 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects the line connecting both the end portions of the storage unit.

12. The powder supply device according to claim 9 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects a line connecting both end portions of the storage unit.

13. The powder supply device according to claim 9 , wherein the magnetic body is a magnetic body in which a plurality of the S poles and a plurality of the N poles are arranged in parallel at equal intervals.

14. The powder supply device according to claim 1 , wherein

the magnetic body has an S pole and an N pole that are magnetized so as to be arranged in a direction in which a bottom surface of the storage unit extends.

15. The powder supply device according to claim 14 , wherein the S pole and the N pole of the magnetic body extend along a line connecting both end portions of the storage unit.

16. The powder supply device according to claim 15 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects a line connecting both end portions of the storage unit.

17. The powder supply device according to claim 14 , wherein a distance between the S pole and the N pole at least in a vicinity of the discharge port in the magnetic body is shorter than a dimension of the discharge port in a direction that intersects a line connecting both end portions of the storage unit.

18. The powder supply device according to claim 14 , wherein the magnetic body is a magnetic body in which a plurality of the S poles and a plurality of the N poles are arranged in parallel at equal intervals.

19. The powder supply device according to claim 1 , wherein the magnetic body is a rubber magnet.

20. The powder supply device according to claim 1 , further comprising:

a transport unit including

a first transport unit that transports the mixed agent stored in the storage unit toward one of a first end portion and a second end portion opposite to the first end portion, and

a second transport unit that is closer to the first end portion than the first transport unit, the second transport unit that applies a transporting force to the mixed agent in an opposite direction to a direction in which the first transport unit applies a transporting force to the mixed agent.
