INKJET PRINTER

In a case where suction means for taking in outside air into an inkjet printer is provided, a heated recording medium is abruptly cooled by a flow of air, thereby causing cooling unevenness, which is a factor of degradation of image quality. Further, it is difficult to efficiently cool an inside of a carriage. In view of the above, provided are a structure for allowing the outside air, which is taken into a device of the inkjet printer, to be directly sucked into the carriage, and a structure for preventing the outside air from passing through the carriage. Thus, the temperature inside the carriage can be effectively decreased. Further, mechanisms for exhausting the gas are provided on both sides of a housing, specifically, one mechanism is provided on a side surface of the housing and another mechanism is provided on a rear surface thereof. Thus, unevenness of exhausted gas can be suppressed at the right and left of the housing.
