Abstract

A medium support portion including a support face that supports a medium, a heater configured to heat a surface of the medium remotely from the support face, an airflow supply unit configured to supply airflow, along the surface of the medium, to a region between the medium and the heater, a plurality of heater support portions that support the heater, and at least one first temperature detection unit located remotely from the support face and configured to detect a spatial temperature in the region that is in contact with the surface of the medium are provided, in which the at least one first temperature detection unit is disposed between two mutually adjacent heater support portions among the plurality of heater support portions.

First claim

What is claimed is:

1. A heating device, comprising:
a medium support portion including a support face that supports a medium;
a heater configured to heat a surface of the medium remotely from the support face;
an airflow supply unit configured to supply airflow, along the surface of the medium, to a region between the medium and the heater;
a plurality of heater support portions that support the heater; and
at least one first temperature detection unit away from the support face and configured to detect a spatial temperature in the region, wherein
the at least one first temperature detection unit is disposed between two mutually adjacent heater support portions among the plurality of heater support portions.

2. The heating device according to claim 1 , wherein
two or more of the first temperature detection units are arranged between the two mutually adjacent heater support portions among the plurality of heater support portions.

3. The heating device according to claim 1 , comprising
a transport unit configured to transport the medium wherein
the at least one first temperature detection unit is disposed downstream of the heater in a transport direction in which the medium is transported.

4. The heating device according to claim 1 , wherein
a plurality of the airflow supply units are arranged in a direction intersecting a flow direction of the airflow, and
the at least one first temperature detection unit is disposed upstream of the heater in the flow direction of the airflow.

5. The heating device according to claim 1 , wherein
a space between the heater and the region along the surface of the medium is partitioned by a net body and
the at least one first temperature detection unit is disposed on a side of the heater with respect to the net body.

6. The heating device according to claim 1 , wherein
the medium support portion includes at least one second temperature detection unit in addition to the first temperature detection unit, and
the at least one second temperature detection unit is disposed at a position corresponding to a position between the two mutually adjacent heater support portions among the plurality of heater support portions.

7. A recording apparatus, comprising:
a medium support portion including a support face that supports a medium;
a recording unit configured to perform recording on the medium;
a heater configured to heat a surface of the medium remotely from the support face;
an airflow supply unit configured to supply airflow, along the surface of the medium, to a region between the medium and the heater;
a plurality of heater support portions that support the heater; and
at least one first temperature detection unit located remotely from the support face and configured to detect a spatial temperature in the region, wherein
the at least one first temperature detection unit is disposed between two mutually adjacent heater support portions among the plurality of heater support portions.
