ABSTRACT:
A heat-sensitive transfer type recording device is provided with a thermal head having heat generating elements and a backing roll operatively positioned relative to the heat generating elements to accommodate the passage of an ink donor sheet and a recording sheet therebetween under pressure. A separation roll is spaced from the backing roll to provide for the passage of said ink donor sheet and said recording sheet therebetween at a pressure substantially less than the pressure exerted on the sheets upon passage between the backing roll and the heat generating elements. The ink donor sheet is directed about the separation roll at a relatively sharp angle to separate the recording sheet from the ink donor sheet with a complete transfer of the ink from the ink donor sheet to the recording sheet as a result of the reduced pressure on the sheets at the separation roll.
