  • Patent number: 8740376
    Abstract: An ink jet printer includes a liquid recording head that is arranged at a halfway position of a transportation path of a sheet to be transported to a downstream side from an upstream side, and performs surface print processing by adhering ink to a surface of the sheet, a drying device that is arranged so as to be spaced from the liquid recording head on the transportation path, and an exhaust fan that generates airflow for suppressing heat transfer from the drying device to the liquid recording head between the liquid recording head and the drying device.
