Abstract

A drying device for drying a medium that has had a liquid ejected thereon includes a guide that the medium that has had the liquid ejected thereon abuts against, a tension control section that is capable of providing tension to the medium that is abutted against the guide, a heating section capable of heating the medium, and a cooling section capable of cooling the medium that has been heated by the heating section, wherein the tension control section is capable of generating a pressing force that presses the medium against the guide, and the heating by the heating section and the cooling by the cooling section are performed on the medium while the tension and the pressing force are being applied to the medium.

First claim

What is claimed is:

1 . A drying device for drying a medium that has had a liquid ejected thereon comprising:
a guide that the medium that has had the liquid ejected thereon abuts against, a tension control section that is capable of providing tension to the medium that is abutted against the guide, a heating section capable of heating the medium, and a cooling section capable of cooling the medium that has been heated by the heating section, wherein the tension control section is capable of generating a pressing force that presses the medium against the guide, and the heating by the heating section and the cooling by the cooling section are performed on the medium while the tension and the pressing force are being applied to the medium.

2 . The drying device according to claim 1 ,
wherein the guide is a transport drum that has a cylindrical form and that transports the medium on a circumferential surface of the transport drum.

3 . The drying device according to claim 1 ,
wherein the guide abuts against the medium and includes a convex curved surface that protrudes toward the medium.

4 . A printing apparatus comprising:
an ejecting section that ejects a liquid onto a medium; and the drying device according to claim 1 .

5 . A printing apparatus comprising:
an ejecting section that ejects a liquid onto a medium; and the drying device according to claim 2 .

6 . A printing apparatus comprising:
an ejecting section that ejects a liquid onto a medium; and the drying device according to claim 3 .

7 . A drying method that dries a medium that has had a liquid ejected thereon, the drying method comprising:
abutting the medium that has had the liquid ejected thereon against a guide, providing tension to the medium that is abutting against the guide, heating the medium, and cooling the medium that has been heated, wherein the providing of the tension to the medium includes generating a pressing force that presses the medium against the guide, and the heating of the medium and the cooling of the medium are performed while the medium is abutted against the guide by the abutting of the medium against the guide and while the tension is provided to the medium and the pressing force is generated on the medium by the providing of the tension to the medium.
