<p>PURPOSE:To facilitate, in a laser vaporization type printer using vaporizable dyestuff, temperature control for liquefaction and heat retaining of vaporizable dyestuff, to achieve energy conservation, to enhance vaporization speed, and to use a laser beam source for a long time. CONSTITUTION:A heating element 16 for liquefaction and heat retaining of solid vaporizable dyestuff is also used as a photothermic conversion body and a transparent heating element is used as a heating element for liquefaction and heat retaining, whereby the heating element 16 can be disposed even in a vaporizing section 17, and further the section 17 together with a liquid vaporizable dyestuff introducing section 15 can be temperature controlled. And by providing a heat insulating means near the section 17 and by preventing dispersion of laser beam to collect it by means of a lens, a spot formed on the photothermic conversion body is made smaller than a transferred spot. By this method, energy conservation is achieved and thermal efficiency is enhanced.</p> |
