## Abstract

A liquid ejecting device includes an ejecting head configured to eject liquid to a medium, a conveyance belt including an adhesive layer to which the medium is bondable, the conveyance belt being configured to convey the medium with the adhesive layer, a heating unit configured to heat the conveyance belt, a pressing unit configured to press the medium against the conveyance belt heated by the heating unit, a channel member configured to define a channel of the liquid to be supplied to the ejecting head, an airflow generation unit configured to generate airflow to be jetted to the conveyance belt past the pressing unit, and a heat exchange mechanism configured to exchange heat between a heat absorption unit configured to absorb heat and a heat dissipation unit configured to emit heat. The heat dissipation unit makes contact with the channel member, and the heat absorption unit is disposed in a course of an airway path through which the airflow moves.

## Claims

### Claim 1

A liquid ejecting device comprising:
an ejecting head configured to eject liquid to a medium;
a conveyance belt including an adhesive layer to which the medium is bondable, the conveyance belt being configured to convey the medium with the adhesive layer;
a heating unit configured to heat the conveyance belt;
a pressing unit configured to press the medium against the conveyance belt heated by the heating unit;
a channel member configured to define a channel of the liquid to be supplied to the ejecting head;
an airflow generation unit configured to generate airflow to be jetted to the conveyance belt past the pressing unit; and
a heat exchange mechanism configured to exchange heat between a heat absorption unit configured to absorb heat and a heat dissipation unit configured to emit heat, wherein
the heat dissipation unit makes contact with the channel member, and
the heat absorption unit is disposed in a course of an airway path through which the airflow moves.

### Claim 2 (depends on 1)

The liquid ejecting device according to claim 1, further comprising a housing unit including an internal space configured to house the ejecting head and the heat exchange mechanism, wherein
the channel member is in communication with the ejecting head through an inside of the housing unit;
the airway path is configured such that the airflow from the airflow generation unit is sent into the housing unit; and
the housing unit includes an outlet configured to blow, to the conveyance belt, the airflow sent into the housing unit.

### Claim 3 (depends on 2)

The liquid ejecting device according to claim 2, wherein when a portion facing the ejecting head in the conveyance belt is an opposing portion, the outlet is provided downstream of the ejecting head in a movement direction of the opposing portion.

### Claim 4 (depends on 2)

The liquid ejecting device according to claim 2, wherein when a portion facing the ejecting head in the conveyance belt is an opposing portion, the outlet is provided upstream of the ejecting head in a movement direction of the opposing portion.

### Claim 5 (depends on 2)

The liquid ejecting device according to claim 2, further comprising a heat absorption fin including a plurality of protrusions and housed inside the housing unit, wherein
the heat absorption fin is coupled with the heat absorption unit.

### Claim 6 (depends on 5)

The liquid ejecting device according to claim 5, wherein
the airway path includes an airway member configured to define a path through which the airflow moves in the housing unit; and
the airway member causes the airflow to pass through at least one of spaces between the protrusions adjacent to one another.

### Claim 7 (depends on 2)

The liquid ejecting device according to claim 2, wherein the heat absorption unit is located between the heat dissipation unit and the ejecting head.
