PURPOSE:To prevent sucked dust and dust diffused in an inside from sticking to a thermal head, an ink sheet, and recording paper by a method wherein a passage of an air flow with a cooling fan is isolated from a recording part, an ink sheet, and recording paper with a partition member. CONSTITUTION:Air sucked outside an apparatus with a cooling fan 8 is carried in the arrow (f) direction along an upper surface of a sheet protective plate 14, does not pass a gap between the sheet protective plate 14 and a thermal head 3 with an elastic sheet 15, or otherwise does not pass a gap between side plates 12, 13 and the thermal head 3 with elastic sheets 16, 17, and passes inside a slit 7a of a heating plate 7 to carry heat of the heating plate 7 out. Dust sucked outside the apparatus and dust diffused inside the apparatus come not to stick to the thermal head 3, an ink sheet 2, and recording paper 1 thereby. |
