Abstract
A shaft assembly for a thermal printer system for applying loads in an adjustable manner along the length of a thermal print head of the thermal printer system. The shaft assembly includes a shaft, and a plurality of cam mechanisms rotatably mounted on the shaft and adapted to apply respective loads to the thermal print head at respective locations along the length of the thermal print head. Each cam mechanism is rotationally coupled with an adjacent cam mechanism, and is adapted to be rotated from a non-load-applying position to load-applying position and from the load-applying position to subsequent load applying positions. Each cam mechanism is adapted to apply a respective load to structure associated with the thermal print head when the cam mechanism is in any of its load-applying positions. Each cam mechanism engages the adjacent cam mechanism as the cam mechanism rotates from its load-applying position to its first subsequent load-applying position to cause the adjacent cam mechanism to rotate from its non-load applying position to its load-applying position and to cause the adjacent cam mechanism to apply a respective load of the adjacent cam mechanism. The cam mechanisms may have any suitable profiles and may be rotationally coupled together in any suitable manner.
