ABSTRACT:
A thermal transfer printer includes a sheet feed roller and a pinch roller cooperating to reciprocate a sheet, a motor providing the sheet feed roller with drive force, a thermal head6performing thermal transfer, and a controller controlling a series of operations. The sheet feed roller has a helical gear attached thereto to transmit the motor's drive force. In shifting from a sheet feeding operation to an image printing operation a reverse operation is performed to rotate the motor in a direction opposite to that of the sheet feeding operation, with the thermal head detached from the sheet, to previously offset the sheet together with thrust play of shaft.
