<p>PROBLEM TO BE SOLVED: To efficiently suck and remove a dye discharged by sublimation in a recording apparatus subliming and removing the sublimable dye on the surface of a recording medium by the irradiation with laser beam. SOLUTION: A mouthpiece member 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 so as to surround an object lens 4 and the circular arc surface 13 formed on the front thereof is allowed to approach the rotary drum 2 and the interval between both of them is reduced. By this constitution, the leak of the dye discharged into the front space 14 of the lens to the circumference is prevented and the suction passage 15 formed to the mouthpiece member 12 is connected to a suction blower through a suction hose 20 to efficiently suck and remove the dye from the front space 14 of the lens.</p> |
