| 摘要 | PURPOSE:To provide a high speed and high quality thermal transfer recording apparatus without choice in the surface configuration of a receiving article, by providing a recording head for selectively heating a thermal transfer medium and a transfer/fixing means for transferring heat-meltable ink in a non- supercooling state. CONSTITUTION:A thermal transfer film 3 delivered from a film supply roller 4 and contacted with a recording electrode at the edge part of a current supply recording head 7 is constituted so that the substrate layer thereof has ductility and, therefore, the selected part of an ink layer is melted under heating perfectly independent of the surface state of receiving paper 1. Thereafter, ink is pressurized by a transfer/fixing means 8 to be transferred to the receiving paper 1. When ultrasonic energy generated by the ultrasonic oscillator 84 in the transfer/fixing means 8 reaches the heat-meltable ink layer, the ink transfers from an supercooling state to a non-supercooling state and, therefore, said ink is strongly fixed. Further, because all stored energy is emitted and the ink layer is reheated to be lowered in its viscosity and the receiving paper 1 is heated, transfer efficiency is more enhanced. | ||||||
