Image Number 4 for United States Patent #6380964.
The present invention is directed to a thermal transfer recording apparatus, and an object is to prevent causes of print failure, such as wrinkling and transport failure of an ink sheet, resulting from the partial shrinking of the ink sheet due to the heating of the thermal head during printing. The thermal transfer recording apparatus of the present invention comprises a thermal head and a platen roller opposed to the thermal head, and prints on a sheet by causing a wax, a sublimation dye, or the like applied on the ink sheet to melt or sublime by the heat of the thermal head. The thermal transfer recording apparatus is constructed so that the take-up tensile force applied to the ink sheet is made greater at both edges of the ink sheet than at the center thereof.
