<P>PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus, which suppresses temperature rise of a liquid jetting head to prevent viscosity of ink from being changed, and in which degradation of image quality due to a change in the viscosity of the ink is not caused. <P>SOLUTION: The liquid jetting apparatus includes: a carriage 14 that makes the liquid jetting head relatively scan a recording medium S; a first chamber 30 that accommodates the carriage; a heater that increases temperature of the recording medium to which the liquid has been jetted by the liquid jetting head; a second chamber that accommodates the heater; a first bellows 40 whose one end is attached to one side surface of the carriage and whose another end is attached to the first chamber; a first suction valve 41 that sucks gas from the outside of the first chamber into the first bellows following elongation after contraction of the first bellows; a first exhaust valve 42 that exhausts the gas from the inside of the first bellows into the first chamber; a second bellows 50 whose one end is attached to the another side surface of the carriage and whose another end is attached to the first chamber; a second suction valve 51 that sucks the gas from the outside of the first chamber into the second bellows following elongation after contraction of the second bellows; and a second exhaust valve 52 that exhausts the gas from the inside of the second bellows into the first chamber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
