20130328963 | INKJET PRINTER - When an infrared-ray radiation device is arranged immediately above an ink jet head, the infrared-ray radiation device causes the temperature of a carriage to rise, resulting in ejection failure of ink. Further, employing a heat insulation material for the carriage requires cost and space for the heat insulation material. Even when a fan is mounted to an apparatus to introduce outside air, the temperature in the vicinity of the carriage is not easily decreased because the carriage is located at the center of the apparatus. When the outside air is actively introduced in a direction toward the carriage, the following problems arise. That is, the temperature of a recording medium is dropped, and hence the ink landing on the recording medium causes fixing failure. Further, the air is led to a nozzle surface of the ink jet head, and hence ejection failure occurs. Therefore, there is adopted a structure in which the outside air taken into the apparatus is directly taken into the carriage so that the temperature inside the carriage can be set close to the temperature of the outside air regardless of the temperature inside the apparatus, to thereby enable stable ejection by the ink jet head. At the same time, the outside air taken into the apparatus is discharged out of the apparatus through a duct located at a position away from a print surface, to thereby prevent decrease in temperature of the recording medium and ejection failure of the ink from the ink jet head. | 12-12-2013 |
