Principle of operation of parallelism change with the “Cam Tension Base Adjust”:
Though the operation on the front side “Cam Tension Base Adjust” is explained here,
the same principle applies to “Cam Tension Base Adjust” on the rear side.
The horizontal parallelism of the “Ribbon Sensor Frame F” Block (movable part) with
respect to the “SA Ribbon Frame” (fixed part) can be changed by means of the
eccentric mechanism in the “Cam Tension Base Adjust”.
The “Cam Tension Base Adjust” has projections “a” and “b”. The projection “a” is
inserted into the slotted hole “a’ ” in the “SA Ribbon Frame” (fixed part), while the
projection “b” is inserted into the hole “b’ ” in the “Ribbon Sensor Frame F” Block
(movable part).
As you can see from the figure, the projection “a” is eccentric with respect to the
projection “b”. Accordingly, as your turn the “Cam Tension Base Adjust” (after loosening
screws “A” (2 pcs.) and “B”), the eccentric projection “a” pushes the slotted hole “a’ ” so
that the “Ribbon Sensor Frame F” Block (movable part) itself turns around the
supporting point “c”. (The “Ribbon Sensor Frame F” Block (movable part) turns in the
same direction as you turn the “Cam Tension Base Adjust”.)
