PURPOSE:To cool a thermal head without obstructing the control of lamp temp. CONSTITUTION:A thermal head 15 and fixing ultraviolet lamps 16, 17 are provided to the outer periphery of a platen drum 12. A cooling fan 21 is arranged on the rear surface side of the thermal head 15 to blow cooling air against the thermal head 15. An air guide plate 20 is attached to the rear surface of the thermal head 15. The cooling air from the cooling fan 21 is blown against the rear surface of the thermal head 15 to be deflected by the air guide plate 20 so as not to strike against the ultraviolet lamps 16, 17. |
