ABSTRACT:
A thermal transfer recording apparatus wherein it comprises a power transmitting device for transmitting power from a driving motor of the apparatus to a platen roller of the apparatus, which device can change rotational speed of the platen roller to rotate the platen roller at high speed, thereby shortening a non-printing time such as required for introduction and ejection of a recording paper to reduce the total recording time of the thermal transfer recording apparatus. Further, the power transmitting device has a neutral position where the platen roller can be freely rotated, thereby easily restoring the recording apparatus to its normal conditions even when the recording paper and/or an inked ribbon is jammed.
