READER DRIVE ASSEMBLY
SUBJECT:
CHANGE OF SHAPES OF MEMBER PARTS
Reason :
Measure for noise
Outline :
The gear pulley overlapping the idler gear has a depression on the flange due to
molding. If the shaft leans, and consequently the idler gear is lifted, the idler gear
might come into contact with the depression on the flange, resulting in noise. As
a measure for it, round ribs are added to the top and under surfaces of the 45T
gear (FU3-0076) and to the under surface of the 37T pulley/16T gear
(FU3-0075).

remove it.
