Abstract
PURPOSE: To maintain nearly a constant tension acted on an ink ribbon regardless of running direction of the ink ribbon by reducing the braking force applied on the ink ribbon when the ink ribbon runs in a reverse direction of the printing carriage.
CONSTITUTION: When an ink ribbon 3 is wound around a spool 4, the more resistance of a resistor 33 develops less braking force applied to the ribbon with a motor 7. When the ribbon 3 is wound around the spool 5, the more resistance of a resistor 34 develops less braking force applied to the ribbon 3 with the motor 6. According, when the motors 6, 7 allow to have the same rating, and the ribbon 3 is wound around the spool 5, that is, running in a opposite direction of a printing belt 1, the braking force acting on the ribbon 3 can be reduced to maintain a constant tension acted on the ribbon 3 regardless of running direction of the ribbon 3 by allowing the resistance of the resistor 34 to set larger value than the resistance of the resistor 33.
