Abstract

A recording device includes a recording head housed in a carriage, and for discharging a droplet on an obverse surface of a medium to perform recording on the medium, a support section having a support surface for supporting a reverse surface of the medium, and a heater for heating the droplet adhered to the obverse surface of the medium. The carriage is provided with a collection section capable of collecting steam generated when the droplet is heated by the heater. The recording head includes a nozzle cover provided with a plurality of holes for discharging the droplet. The nozzle cover includes a nozzle surface opposed to the support surface The collection section is formed of a material higher in hydrophilic property than the nozzle surface.

First claim

What is claimed is:

1. A recording device comprising:
a carriage configured to reciprocate in a first direction;
a recording head housed in the carriage, and configured to discharge a droplet on an obverse surface of a medium to perform recording on the medium;
a support section including a support surface configured to support a reverse surface of the medium; and
a heating section configured to heat the droplet adhered to the obverse surface of the medium, wherein
the carriage is provided with at least one collection section configured to collect steam generated when the droplet is heated by the heating section,
the recording head includes a nozzle cover provided with a plurality of holes configured to discharge the droplet,
the nozzle cover includes a nozzle surface opposed to the support surface, and
the collection section is formed of a material higher in hydrophilic property than the nozzle surface, and is disposed at a lower surface of the carriage, and at a position different from the nozzle surface.

2. The recording device according to claim 1 , wherein
a thermal diffusivity per unit volume of the at least one collection section is lower than a thermal diffusivity per unit volume of the nozzle cover.

3. The recording device according to claim 1 , wherein
the at least one collection section is integrally formed with the carriage.

4. The recording device according to claim 1 , wherein
the at least one collection section includes a first collection section and a second collection section, and the first collection section and the second collection section are disposed to sandwich the recording head in a second direction intersecting the first direction.

5. The recording device according to claim 1 , wherein
the at least one collection section includes a collection surface opposed to the support surface, and
a distance from the support surface to the collection surface is equal to a distance from the support surface to the nozzle surface.

6. The recording device according to claim 5 , wherein
a surface roughness of the collection surface is higher than a surface roughness of the nozzle surface.

7. The recording device according to claim 6 , wherein
the surface roughness of the collection surface is no less than 0.012 μm and no more than 6.3 μm.

8. The recording device according to claim 1 , further comprising:
a wiper configured to have contact with the collection section and is disposed on a path through which the collection section passes.
