Shut-off Mechanism

The shut-off and change Functions are de-
termined b the position of the cam Follower
lever (166). After every start or record
drop the cam follower lever (166) is moved
to stop position by main lever (173) (longer
end of the cam follower lever towards the
center of the main cam).

As the record is dropped the cam follower
lever (166) is turned to start position by
cam rocker (A) so that the toneerm can suing
in after record drop and be lowered onto it.
If there are no more records on the spindle
its downwerd movement is locked and the cam
rocker cannot turn the cam Follower lever,
the lever remains in stop position and cau-
ses the tonearm to lower onto its rest.

Uhen main com (161) returns to neutral posi-
tion the lug of shift arm (187) is able to
move into the recess provided in the main
cem, ectuate power switch (140) and disenga-
ge idler wheel (150).
