Drive mechanism for thermal transfer type line recorder
 A drive mechanism for a thermal transfer type line recording apparatus is implemented with only two drive motors in driving three essential members of the recorder i.e., platen, ink sheet, and thermal head. While a first drive motor is exclusively assigned to the platen, a second drive motor is shared by the ink sheet, which is fed in one direction only, and the thermal head, which is released from the platen without any intermediary actions concerning the sequence. The second drive motor feeds the ink sheet while in rotation in one direction and drives the thermal head while in rotation in the other direction, each through a one-way clutch.
