Abstract

A drying device is provided and includes: plural light emitting units that are disposed with intervals along a transport direction in which a transported body containing liquid is transported and that cause the liquid to be evaporated by irradiating the transported body with light; and a vent mechanism in which a supply unit and a discharge unit are alternately disposed in spaces on an upstream side and a downstream side of the entirety of the plural light emitting units in the transport direction and spaces between the light emitting units along the transport direction. The supply unit supplies air toward the transported body along the irradiating direction of the light, and the discharge unit discharges air in an opposite direction to the irradiating direction from the transported body side.

First claim

What is claimed is:

1. A drying device comprising:
a plurality of light emitting units that are disposed with intervals along a transport direction in which a transported body containing liquid is transported and that cause the liquid to be evaporated by irradiating the transported body with light in an irradiating direction; and
a vent mechanism including a supply unit and a discharge unit, the supply unit including a plurality of supply ducts for supplying air toward the transported body along the irradiating direction, the discharge unit including a plurality of discharge ducts for discharging air in an opposite direction to the irradiating direction from a side of the transported body, the supply ducts and the discharge ducts being alternately disposed in spaces in the vent mechanism, the spaces including (i) a space formed upstream relative to a light emitting unit disposed on most upstream side of the plurality of light emitting units in the transport direction, (ii) spaces formed between the light emitting units, and (iii) a space formed downstream relative to a light emitting unit disposed on a most downstream side of the plurality of light emitting units in the transport direction.

2. The drying device according to claim 1 ,
wherein the supply unit supplies air having a humidity lower than a humidity in an inside of the drying device.

3. The drying device according to claim 1 ,
wherein the spaces have lengths in a longitudinal direction intersecting the transport direction and the irradiating direction, and
wherein a plurality of supply units are disposed along the longitudinal direction of the spaces.

4. The drying device according to claim 1 ,
wherein the spaces have lengths in a longitudinal direction intersecting the transport direction and the irradiating direction, and
wherein a plurality of discharge units are disposed along the longitudinal direction of the spaces.
