<p>In an inkjet printer in which a waveguide is used, a drying speed of ink ejected onto a medium is improved. A propeller member 46 which is rotated and by which microwave is reflection-terminated is attached at a terminal end part of a waveguide 30, and ventilation members 70 and 80 for ventilating the inside of the waveguide 30 are attached at a starting end side and a termination end side of the waveguide 30. The ventilation members 70 and 80 are provided with ventiducts 71 and 81, which are in communication with the insides of ventilation parts 38 and 39, and fans 72 and 82 which are attached to the ventiducts 71 and 81 and provided with built-in heaters. When a medium onto which ink is ejected is inserted into the waveguide 30 from insertion openings 41 and 42 of waveguide main bodies 31 and 32, the ink is dried by microwaves which are supplied by magnetron 43 and reflected by the propeller member 46. Further, since hot air is sent into the waveguide 30 by the fans 72 and 82, drying of the ink is promoted.</p> |
