Thermal recorder

Abstract

Abstract PURPOSE:To enhance preheating efficiency and facilitate the control of a preheating temperature, by providing a preheating ray generator different from a recording heat beam generator, and preheating a particulate developer on a recording medium directly by preheating rays emitted by the preheating ray generator prior to the irradiation with recording heat beams. CONSTITUTION:When preheating rays 15 are emitted from a preheating ray generator 11, the rays 15 are reflected by a rotary polygon mirror 12, are then refracted by a focusing optical system 13, and the refracted rays are scanned on a recording medium 16 rectilinearly in a main scanning direction indicated by an arrow (b). A particulate developer 17 on the medium 16 is thus preheated by the preheating rays 15 to a preheating temperature. A recording heat beam 14 emitted from a recording heat beam generator 10 is similarly scanned along a scanning line on the recording medium 16 with some delay behind the preheating rays 15, whereby the developer 17 at the points heated by the recording heat beam 14 is melted, and is fixed onto the recording medium 16. Thus, the scanning line preheated by the preheating rays 15 is followingly scanned by the recording heat beam 14, whereby a one-scanning-line amount of informations is recorded on the recording medium 16.
