    摘要: A thermal printing apparatus (1) includes an erasing unit (51) and a printing unit (52) that are positioned along a paper guide (53). Between the erasing unit (51) and the printing unit (52), cooling fans (46) are located. The erasing unit (51) has an erasing roller (37) for applying heat to thermal recording paper fed by a paper feeding tray (2) while transporting the paper. The paper is heated by the roller 37, and then cooled slowly in the course of being transported, so that an image is erased from the paper. The fans (46) create and direct a current of air to cool the paper transported by the roller (37). Then, the printing unit (52) prints a new image on the paper.
