PROBLEM TO BE SOLVED: To efficiently suck and remove a dye sublimed at the time of recording to be discharged and to prevent the clogging of a suction hose. SOLUTION: A mouthpiece cartridge 12 is attached to the leading end of a recording head 3 irradiating the recording medium 1 held to the surface of a rotary drum 2 with laser beam in a freely detachable manner and connected to a suction means through a suction hose 13 to suck and remove a dye discharged by the irradiation with laser beam. A large housing space 19 is provided to the mouthpiece cartridge 12 and the sublimed dye in sucked air is bonded to the inner surface of the housing space 19 to be caught to prevent the clogging of the suction hose 13. When the dye bonded to the inside of the housing space 19 becomes much, the mouthpiece cartridge 12 is replaced. |
