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 for ejecting ink onto a recording medium from a plurality of nozzles; a conveyance device for conveying the recording medium; 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 surface of the recording head on which the plurality of nozzles are arranged; a housing having at least the platen and the carriage accommodated therein; a front paper guide arranged on a downstream side of the platen in the conveyance direction, for guiding the recording medium, the front paper guide comprising a heater for heating the recording medium; a housing-suction device arranged on a rear surface side of the housing, for sucking a gas from an outside into an inside of the housing; and a cover connected to the housing in a pivotable manner and having a distal end arranged at a distance from the front paper guide so that the distal end is positioned lower in a vertical direction than the surface of the recording head on which the plurality of nozzles are arranged, wherein the cover is inclined relative to the vertical direction and arranged such that a distance between the cover and the front paper guide is reduced in the conveyance direction, thereby the gas flowing along the conveying direction from the housing-suction device is directed to a portion between the front paper guide and the distal end of the cover, wherein the front paper guide is curved in the vertical direction, wherein a part of the gas sucked by the housing-suction device is discharged through the portion between the front paper guide and the distal end of the cover in at least a length that corresponds to an entire width of the recording medium passing therethrough so that the discharged gas cools the entire width of the recording medium on the front paper guide as the recording medium is conveyed, and wherein a part of the heater, which is arranged on the front paper guide at a position at which the front paper guide is opposed to the distal end of the cover, which is on an upstream side in the conveyance direction of the recording medium, has a higher heating capacity of heating the front paper guide in the width direction of the recording medium than another part of the heater arranged on the downstream side so that the cooling is suppressed.
