Abstract
During the recording where a liquid dye 22 supplied through a dye passage 27 is supplied to a vaporizing means 17 due to the capillarity of many small columns 21 within a vessel formed by coupling of a glass base 14 and a Teflon protection plate 290, the liquid dye in the vaporizing means is vaporized by irradiation of the laser beam L and the vaporized dye is transmitted to a photographic paper 50 passing a vaporization hole (aperture) 23 for the purpose of recording. The protection plate 290 has a critical surface tension against the liquid dye which is smaller than a surface tension of the liquid dye. Since the critical surface tension of the protection plate 290 is set smaller than a surface tension of the liquid dye, wettability of the liquid dye against the internal wall surface of the vaporizing hole 23 is low and the liquid dye left unvaporized at the vaporizing hole 17 at the time of recording is never deposited on the internal wall surface of the vaporizing hole. Therefore, the vaporizing hole is always kept clear, transfer of the vaporized dye 32 to the photographic paper is never prevented due to deposition of dye to the vapotizing hole and thereby excellent recording quality can always be guaranteed.
