Abstract

A printing apparatus includes a transport unit 30 that transports a medium M in a transport direction F, a printing unit that prints on a printing surface M1 of the medium M, and a removal unit 60 that is provided on an upstream side in the transport direction F with respect to the transport unit 30 and is provided so as to come into contact with the printing surface M1.

Claims

1. A printing apparatus comprising:

a transport unit that transports a medium in a transport direction;

a printing unit that prints on a printing surface of the medium; and

a removal unit that is provided on an upstream side in the transport direction with respect to the transport unit,

wherein the removal unit includes a removal member that is in contact with the printing surface and a holding member that holds the removal member, and

wherein the removal member is an aggregate of fibers.

3. The printing apparatus according to claim 1,

wherein the removal member has a conductive property.

4. The printing apparatus according to claim 1,

wherein the transport unit includes a plurality of rollers, and

wherein the removal member is in contact with the printing surface upstream of a roller in the transport direction, the roller being positioned furthest on the upstream side in the transport direction among the plurality of rollers.

5. The printing apparatus according to claim 1, further comprising:

a setting unit in which a rolled body is mounted and which reels out the medium to the transport unit, the rolled body being in which the medium is wound,

wherein the removal member is in contact with the printing surface between the setting unit and the transport unit in the transport direction.

6. The printing apparatus according to claim 1,

wherein a surface of the holding member to which the removal member is fixed is inclined to the upstream side in the transport direction with respect to a direction that is orthogonal to the printing surface.

7. The printing apparatus according to claim 1,

wherein an angle formed by a surface of the holding member to which the removal member is fixed and the printing surface is equal to or larger than 60°

and is equal to or smaller than 90°

.

8. The printing apparatus according to claim 1,

wherein the removal member extends along a transverse axis direction and curves in the transport direction while the medium is transported in the transport direction, the transverse axis direction being orthogonal to both the transport direction and vertical direction.

9. The printing apparatus according to claim 8,

wherein the removal member is configured by at least one of a non-woven fabric, a felt, and a cloth.

10. The printing apparatus according to claim 1,

wherein the removal member is configured by at least one of a non-woven fabric, a felt, and a cloth.
