Abstract
A hot melt ink jet printing device 1 includes guides 27 disposed on a printing surface 11 of a platen 12 at both sides of a print area and guides 28 disposed downstream side of the platen 12 in a sheet feed direction F. Heaters 21, 25 are mounted on an under surface of the platen 12 for applying heat to a recording sheet 7 placed on the printing surface 11. The print head 13 is disposed away from the platen 12 such that a nozzle surface 13a of the print head 13 confront the printing surface 11. The guides 27, 28 effectively prevent the recording sheet 7 from rising off the printing surface 11 toward the print head 13 when the recording sheet 7 is supplied with heat from the heater 21, 25. In this way, the recording sheet 7 is prevented from contacting the nozzle surface 13a.
