ABSTRACT:
A thermal printer for printing on sheets of paper includes a drive motor having a gear train rotatably connected thereto. A ribbon take-up roll is rotated by rotation of the drive motor via the gear train and a thermal transfer ribbon is taken up by the ribbon take-up roll. A platen is provided on which a sheet of paper and the thermal transfer ribbon are held together during printing. A thermal head is supplied with electric printing signals when the thermal transfer ribbon and the sheet are held on the platen and selectively transfers ink from the thermal transfer ribbon to the sheet based on the electric printing signals. An electromagnetic actuator is actuated when no electric printing signals are supplied to the thermal head and a prescribed blank portion which need not be printed exists. While the actuator moves the thermal head away from the platen, the detent plate simultaneously engages with a gear of the gear train by movement of an actuator plate spring to stop rotation of the gear. A clutch mechanism operates when the detent plate is engaged and stops transmission of rotation of the drive motor to the ribbon take-up roll.
