Claim Text:
1. An inkjet printer for recording an image on a recording medium by ejecting ink onto the recording medium from a recording head while intermittently conveying the recording medium, the inkjet printer comprising: a recording head having a plurality of nozzles for ejecting ink onto a recording medium from the plurality of nozzles; a carriage having the recording head mounted therein, the carriage being reciprocable in a direction intersecting with a conveyance direction of the recording medium; a platen for retaining the recording medium, the platen being arranged so as to be opposed to a lower surface side of the carriage; a heater provided in the platen for heating the recording medium; conveyance means for conveying the recording medium; a housing having at least the carriage accommodated therein; a housing suction fan for sucking a gas from an outside into an inside of the housing, the housing suction fan being arranged on a rear surface of the housing so as to be opposed to a rear surface of the carriage; a rear surface exhaust fan for exhausting the gas inside the housing to the outside, the rear surface exhaust fan being arranged on the rear surface of the housing; a side surface exhaust fan for exhausting the gas inside the housing to the outside, the side surface exhaust fan being arranged on a side surface of the housing; a carriage suction fan for sucking the gas, which is sucked by the housing suction fan, into the carriage, the carriage suction fan being arranged on the rear surface of the carriage so as to be opposed to the housing suction fan; a front paper guide for guiding and heating the recording medium, the front paper guide being arranged on a downstream side of the platen in the conveyance direction; and a cover arranged at a distance from the front paper guide and connected to the housing so that a distal end portion thereof is positioned lower in a vertical direction than a surface of the recording head on which the plurality of nozzles are arranged, wherein the housing suction fan has a height along the vertical direction which is larger than a height of the carriage suction fan along the vertical direction, wherein when the housing suction fan and the carriage suction fan are arranged at positions opposed to each other, the gas sucked by the housing suction fan is sucked into the carriage by the carriage suction fan and flows into the housing without being sucked by the carriage suction fan, wherein the gas, which is sucked into the carriage by the carriage suction fan, is discharged to the inside of the housing toward the cover, and wherein the gas sucked by the housing suction fan is at least discharged to the outside of the housing from the rear surface exhaust fan, the side surface exhaust fan, and a clearance between the front paper guide and the cover.
