PURPOSE:To control the temperature of an ink by winding an ink feeding metal tube with an insulation-film-coated electric resistance wire while a temperature detection sensor is press mounted before and after the wound section. CONSTITUTION:A metal tube 1 for feeding an ink to an ink jet head is wound on the circumference with an insulation-film-coated electric resistance wire 5a while temperature detection sensors 14a and 14b are press mounted detachably before the wound section. The metal tube 1 preferably uses a stainless pipe. It is preferable to reduce thickness thereof to a large extent because of enhancing the thermal response of the pipe. |
