PROBLEM TO BE SOLVED: To stabilize the discharging by reducing unevenness in the head temperature in a line type liquid droplet discharging head for which nozzles are highly densely arranged into a two-dimensional matrix shape. SOLUTION: For this liquid droplet discharging head, a plurality of discharging ports which discharge liquid droplets are arranged into a two-dimensional shape. The liquid droplet discharging head is equipped with a plurality of heat pipes which are arranged in the longitudinal direction of the liquid droplet discharging head in a vicinity of a pressure chamber which communicates with the discharging ports. Then, the flowing directions of a solvent between a plurality of the heat pipes are intermingled for each heat pipe for the liquid droplet discharging head. COPYRIGHT: (C)2007,JPO&INPIT |
