Abstract
A printer using a thermal ribbon to print on paper with a thermal head facing a platen with a ribbon supply core and take-up core with the head between the cores wherein a tension member contacts and biases the ribbon in a direction to give tension and is rotated in a retracted direction by a ribbon feed force against a biasing force by the tension member when the ribbon is fed and a plate spring supported on the tension member gives a rotational load to the supply core and a release member separate from the head contacts the ribbon on the platen side of a tangent line of the platen at the printing position whereby a push-up force of the paper in contact with and supported by the release member prevents lowering of print quality as the push-up force is not applied to the thermal head.
