Relation between home position of switching shaft (stopping position) and
stopping position of folding stopper (Reference)
Both folding plates 1 and 2 in electrical design
(theory) are set so that the clearance between the tip
of the folding stopper and folding plate chassis
becomes 3.0 mm (0.12") when the shield blocks the
home sensor.
In mechanical design, this clearance is set to 1.5 mm
(0.06") (–12 pulses).
This is to easily make the inconsistencies of the home
position (stopping position) of the switching shaft
occurring due to the accumulation of parts tolerance
even by electrical correction.
When the folding stopper is stopping at the reference
position, the reference dimensions of the switching
adjusting plate is 7.0 mm (0.28").
When the folding stopper and switching adjusting
plate are stopping at their reference positions, the
reference dimensions of the switching shaft stopping
position is 0.2 mm (0.008").
When the switching shaft stopping position is the
reference dimension, the correction value of the
switching shaft home position is "–12".
