ANTI-SKATING
knob
This
device
cancels

time
eliminates
any
excessive
stylus

groove.
Use
the
@
marked

Lead-in
Mechanism
When

and
main

rotates,
the

rod
moves
the
driver
which
rotates
the
elevator
cam
as
shown

As
the
elevator
cam
moves
with
the
rotation
of
the
driver
toward
A,
the
slope
of
the
elevator
cam
causes
the
elevator
to
rise
which,
in
turn,
lifts
the
tonearm.
The

At

contacts
A
of
the

(see
Figure
