Title:
INKJET PRINTER
Document Type and Number:
WIPO Patent Application WO/2012/117611
Kind Code:
A1
Abstract:
In a structure wherein an infrared-ray irradiation device is arranged directly above an inkjet head, the infrared-ray irradiation device will cause the temperature of a carriage to rise, resulting in poor discharge of ink. Further, employing a heat insulation material in the carriage will incur costs and require space for the heat insulation material. Even if a fan is attached to the device to introduce external air, decreasing the temperature around the carriage is difficult because the carriage is located at the center of the device. If external air is actively introduced and directed to the carriage, there are the problems of the temperature of a recording medium dropping and causing poor adherence of the ink landing on the recording medium, and the wind blowing on a nozzle surface of the inkjet head and causing poor discharge of ink. Therefore, a structure wherein the external air introduced into the device is directly drawn inside the carriage is provided, so that the temperature within the carriage can be made similar to the temperature of the external air regardless of the temperature in the device, to thereby enable a stable discharge from the inkjet head. At the same time, the external air introduced to the device is exhausted out of the device through a duct located at a position away from a print surface, so as to prevent the decrease of the temperature of the recording medium, and poor discharge of ink from the inkjet head.
