Abstract

A drying method includes a heat step of heating the medium, a transport step of transporting the medium in the transport direction, and an air blowing step of blowing air to the medium while heating the transported medium, and the temperature is adjusted in each of the heating step and the air blowing step.

First claim

What is claimed is:

1 . A drying method comprising:
heating a medium with a heater covered in a metallic case; transporting the medium in a transport direction; and blowing air to the medium while heating the transported medium, wherein temperature adjustment is performed during heating and during blowing, and the heating further comprises heating the medium with a first heater which performs temperature adjustment so that a temperature of the first heater is higher than a temperature of a second heater, the first heater being located upstream of the second heater in the transport direction.

2 . A drying device comprising:
a heater covered in a metallic case that heats a medium; a transport section that transports the medium in a transport direction; and a blower configured to blow air to the heated medium, wherein
the heater includes a first heater to which air is not blown by the blower and a second heater to which air is blown by the blower,
the first heater and the second heater each perform temperature adjustment, and
the first heater performs temperature adjustment so that a temperature of the first heater is higher than a temperature of the second heater, the first heater being located upstream of the second heater in the transport direction.

3 . A printing device comprising:
a printing section that performs printing by ejecting ink onto a medium; a heater covered in a metallic case that heats the medium; a transport section that transports the medium in a transport direction; and a blower configured to blow air to the heated medium, wherein
the heater includes a first heater to which air is not blown by the blower and a second heater to which air is blown by the blower,
the first heater and the second heater each perform temperature adjustment, and
the first heater performs temperature adjustment so that a temperature of the first heater is higher than a temperature of the second heater, the first heater being located upstream of the second heater in the transport direction.

4 . The printing device according to claim 3 , wherein
each of the first heater and the second heater includes a medium support that supports the medium and, at least in the first heater, the medium support includes a bent section that changes direction in which the medium is transported.

5 . The printing device according to claim 3 , wherein
the first heater includes a first temperature detection section, the second heater includes a second temperature detection section, and the first temperature detection section and the second temperature detection section are provided at positions overlapping each other in the transport direction.

6 . The printing device according to claim 3 , wherein
the second heater includes an upstream heating section that faces the blower and a downstream heating section that does not face the blower and that is located downstream of the upstream heating section in the transport direction and the upstream heating section and the downstream heating section each perform temperature adjustment.

7 . The method of claim 1 , wherein the heating further comprises heating the medium with each of a first heater and a second heater including a medium support that supports the medium and, at least in the first heater, the medium support including a bent section that changes direction in which the medium is transported.

8 . The method of claim 1 , wherein the heating further comprises heating the medium with a first heater including a first temperature detection section, a second heater including a second temperature detection section, and the first temperature detection section and the second temperature detection section being provided at positions overlapping each other in the transport direction.

9 . The method of claim 1 , wherein the heating further comprises heating the medium with a second heater which includes an upstream heating section that faces a blower and a downstream heating section that does not face the blower and that is located downstream of the upstream heating section in the transport direction and the upstream heating section and the downstream heating section each perform temperature adjustment.

10 . The drying device according to claim 2 , wherein each of the first heater and the second heater includes a medium support that supports the medium and, at least in the first heater, the medium support includes a bent section that changes direction in which the medium is transported.

11 . The drying device according to claim 2 , wherein the first heater includes a first temperature detection section, the second heater includes a second temperature detection section, and the first temperature detection section and the second temperature detection section are provided at positions overlapping each other in the transport direction.

12 . The drying device according to claim 2 , wherein the second heater includes an upstream heating section that faces the blower and a downstream heating section that does not face the blower and that is located downstream of the upstream heating section in the transport direction and the upstream heating section and the downstream heating section each perform temperature adjustment.
