## Abstract

A printing device 11 includes a printing section 16 that performs printing by ejecting a liquid onto a transported medium 99, a support section 21 facing the printing section and having a support surface 22 for supporting the medium, a holding section 26 for holding the medium spanning across from the support section, a heating section 31 that is located downstream of the support section in the transport direction of the medium and that heats the printed medium, and a heat shield section 41 facing the heating section, wherein the heat shield section has a facing surface 43 that faces the heating section and that is separated from the medium extending across from the support section to the holding section, and a protruding section 46 that protrudes from the facing surface toward the heating section at an end portion on a downstream side in the transport direction.

## Claims

### Claim 1

A printing device comprising:
a printing section that performs printing by ejecting a liquid onto a transported medium;
a support section facing the printing section and having a support surface for supporting the medium;
a holding section for holding the medium spanning across from the support section;
a heating section that is located downstream of the support section in the transport direction of the medium and that heats the printed medium; and
a heat shield section facing the heating section, wherein
the heat shield section includes
a facing surface that faces the heating section and that is separated from the medium extending across from the support section to the holding section, and
a protruding section that protrudes from the facing surface toward the heating section at an end portion on a downstream side in the transport direction.

### Claim 2 (depends on 1)

The printing device, according to claim 1, wherein
the protruding section is configured to be displaced between a position protruding from the facing surface toward the heating section and a position housed in the heat shield section.

### Claim 3 (depends on 1)

The printing device, according to claim 1, wherein
the protruding section is configured by a plurality of protrusions.

### Claim 4 (depends on 2)

The printing device, according to claim 2, further comprising:
a drive section configured to drive the protruding section; and
a control section configured to control the drive section, wherein
the control section causes the protruding section to protrude from the facing surface when a printing operation is started, and causes the protruding section to be housed when the printing operation is stopped.

### Claim 5 (depends on 2)

The printing device, according to claim 2, further comprising:
a temperature sensor configured to measure the outside air temperature; and
a power section configured to displace the heat shield section, wherein
the power section displaces the heat shield section so as to change the distance between the heating section and the heat shield section based on the temperature of the outside air measured by the temperature sensor.

### Claim 6 (depends on 5)

The printing device, according to claim 5, further comprising:
a drive section configured to change a protruding amount of the protruding section, wherein
the drive section changes the protruding amount of the protruding section based on the distance between the heating section and the heat shield section.

### Claim 7 (depends on 1)

The printing device according to claim 1, wherein
the protruding section is formed of fabric.
