These two
cams have one CAM GROOVE on both
sides.
A total
of
four
CAM
GROOVES performs
independent
functions
to meet the multi-function
needs of
these
days
by driving
the elements
of
a wide variety of functions
with the motor precisely
controlled
by a microcomputer.
The two
cams are positive
motion
cams having
a
groove
over
570
degrees. These
cams
cause
the
amount
of lift
to be changed
by a mild gradient
according
to
the
angle
of
rotation
while
synch ronizedly
being
rotated
by
an
outer
circumferential
gear to
alleviate
the
load exerted
on the cams when driving
the rod linked with
the
cams and also to ensure position
stability
in each
mode of operation.
The geometry
of each cam and
