Abstract

A printing apparatus includes: a transport unit that transports a medium in a transport direction; a medium support that supports the medium; a medium pressing unit that has a first regulation section that regulates bending of an end portion of the medium from the medium support in a width direction intersecting with the transport direction and a second regulation section that regulates moving of the end portion of the medium to an outer side in the width direction; and a printing unit that performs printing on the medium supported on the medium support.

First claim

What is claimed is:

1. A printing apparatus comprising:
a print head that is configured to discharge ink on a printing surface of a medium;
a transport unit that is configured to transport the medium in a transport direction;
a medium support that includes a support surface that is configured to support the medium;
a first regulation section that is configured to face to an end portion of the printing surface in a width direction intersecting with the transport direction, the first regulation section that is configured to regulate bending of the end portion from the support surface;
a second regulation section that is configured to contact with the end portion in the width direction, the second regulation section that regulates a movement of the end portion to an outer side in the width direction; and
wherein the second regulation section that is provided on the upstream side from the print head in the transport direction,
wherein the first regulation section includes a base plate that comes into the support surface, and
wherein the base plate includes a latching portion that latches to a latching groove of the medium support.

2. The printing apparatus according to claim 1 ,
wherein the first regulation section is formed in plate shape.

3. The printing apparatus according to claim 1 ,
wherein the second regulation section is formed in plate shape.

4. The printing apparatus according to claim 1 ,
wherein the first regulation section and the second regulation section are formed in plate shape.

5. The printing apparatus according to claim 1 ,
wherein the second regulation section is provided on the upstream side from the first regulation section in the transport direction.

6. The printing apparatus according to claim 1 ,
wherein the first regulation section has a plurality of holes that is arranged in the transport direction.

7. The printing apparatus according to claim 1 ,
wherein the first regulation section is movable in the width direction.

8. The printing apparatus according to claim 1 ,
wherein the second regulation section is movable in the width direction.

9. The printing apparatus according to claim 1 ,
wherein the first regulation section and the second regulation section are movable in the width direction.

10. The printing apparatus according to claim 1 ,
wherein the first regulation section has an inclined portion which is inclined to have a gap that is gradually wider from the medium support toward the upstream side in the transport direction.

11. The printing apparatus according to claim 1 ,
wherein the first regulation section, the second regulation section and the base plate are formed through integral molding.

12. The printing apparatus according to claim 1 , wherein the second regulation section is downstream of a medium source.

13. The printing apparatus according to claim 1 , wherein a portion of the first regulation section is recessed in the width direction relative to the second regulation section.
