Abstract
In a thermal transfer recording system, an ink paper cassette containing an ink paper having ink layers and an ink paper feed bobbin with the ink paper wound therearond, and further containing a take-up bobbin for taking up the ink paper fed from the feed bobbin, is used in conjunction with a recording paper, a platen roller, and a thermal head. The recording paper and the ink paper fed from the feed bobbin are disposed in a superimposed manner on the platen roller and are pressed toward the platen roller form the ink paper side and heated by the thermal head, thereby allowing ink to be transferred to the recording paper form the ink paper in accordance with information provided to the thermal head. A discrimination is made as to whether the ink paper cassette is a first ink paper cassette which contains a first ink paper having only ink layers, or a second ink paper cassette which contains a second ink paper having both a receiving layer and ink layers. If the ink paper cassette is judged to be the first ink paper cassette, a first recording paper having a receiving layer is selected, while if the ink paper cassette is judged to be the second ink paper cassette, a second recording paper not having a receiving layer is selected. Consequently, ink is transferred to the selected recording paper from the ink paper contained in the ink paper cassette.
