Adjusting thermal print head pressure

A thermal print head 60 is urged against a platen roller 78 by a leaf spring 124 via an intermediate force transmitting member 162 which has a sloping surface in contact with a rod 92 associated with the print head. Due to the slope of the rod-contacting surface, movement of the intermediate member...

Zusammenfassung:	A thermal print head 60 is urged against a platen roller 78 by a leaf spring 124 via an intermediate force transmitting member 162 which has a sloping surface in contact with a rod 92 associated with the print head. Due to the slope of the rod-contacting surface, movement of the intermediate member 162 in the direction of arrows 182 alters the separation between the spring and the rod 92, thereby adjusting the force exerted on the print head.
