Liquid ejection apparatuses

A liquid ejection apparatus comprising:

• a feeding mechanism configured to feed a recording medium in a first direction;
• a head comprising a nozzle surface in which nozzles are disposed, wherein the head is configured to eject liquid through the nozzles;
• and
• a humidifying mechanism comprising:
• a humidified air generating device configured to generate humidified air;
• an output portion connected to the humidified air generating device, wherein the output portion comprises a first supplying channel with a first opening and a second opening formed therein, wherein an area of the second opening is greater than an area of the first opening, wherein the first opening is separated from the second opening in a second direction perpendicular to the first direction, and wherein the output portion is configured to output the humidified air generated by the humidified air generating device through the first opening and the second opening;
• and
• a receiving portion configured to receive the humidified air output from the output portion,
• wherein the head is disposed between the output portion and the receiving portion in the first direction,
• wherein the output portion comprises a second supplying channel connecting the humidified air generating device to the output portion and configured to supply humidified air to the first and the second openings of the output portion via the first supplying channel,
• wherein the first supplying channel comprises a plurality of openings through which the humidified air generated by the humidified air generating device is output, the plurality of openings including the first opening and the second opening,
• wherein the output portion permits the humidified air generated by the humidified air generating device to be output only through the plurality of openings corresponding to the output portion,
• wherein, for each respective opening of the plurality of openings except each opening adjacent to the second supply channel, an area of such respective opening is greater than an area of an adjacent opening of the plurality of openings that is disposed closer than such respective opening to the second supplying channel in the second direction, and
• wherein the first supplying channel is substantially parallel to the nozzle surface of the head and an entirety of the first supplying channel is disposed further than the nozzle surface from the feeding mechanism in a third direction perpendicular to the first direction and the second direction, such that the first supplying channel is configured to not interfere with conveyance of the recording medium by the feeding mechanism.
