ABSTRACT:
A thermal printer includes a platen roller on which a recording sheet is wound in such a manner that the recording sheet is laid over a part of the cylindrical wall of the platen roller. A thermal head is pushed against the platen roller to heat heating points selected for transferring ink from an ink sheet onto the recording sheet. A sheet pulling means pulls the recording sheet in a predetermined direction. A pinch roller on the sheet supplying side pushes the recording sheet against the platen roller with a predetermined force of depression so that the recording sheet is wound on the platen roller. A pinch roller rotating means is provided at at least one end of the pinch roller for rotating the pinch roller at a peripheral speed lower than that of the platen roller.
