Abstract
A thermal transfer printer in which printing is performed by melting ink from an ink ribbon and transferring the molten ink to a printing sheet, and which is capable of erasing printed characters as desired by attaching the transferred ink to the ink ribbon and drawing the ink ribbon to separate the ink from the printing sheet. At least one ribbon feed roller having its surface formed of a material of a large friction coefficient is provided in a ribbon cassette housing the ink ribbon. The ribbon feed roller is rotated by a drive shaft provided on a carriage to assist in separating the ink ribbon from the printing sheet, thereby enabling the ink ribbon to be separated and wound up constantly with stability during each of the printing and correction operations.
