O REPEAT OPERATION
When
the
repeat
button
is pressed
during record
play, the control
base
unit will
be
as
shown
in
Fig.
9-2.
Lever
D will
thus
not to
move
any further
left
than
a
pre-determined
position.
After the
end
of
the "lead-in"
operation,
the
"auto-return" operation
commences
when
the
end
of record play
is reached.
1.
At
the start
of the
auto-return operation,
cam
A
rotates
to
move
plate A towards the right.
2. Cam C
pushes against
cam
D
to
raise
the
arm
elevation.
3.
Cam
C
pushes
pin
C
of the
PU
plate to the right.
4.
When cam
C
reaches across
to
the right
hand
side,
the
lead-in
latch
grasps
pin C
of
the
PU
plate, resulting
in
the
tonearm being
moved
across
to the
disc.
The main
difference here
to
the
auto-lead-in
operation is
that pin
A
of
lever C
pushes
plate
D
when the repeat
button is
pressed,
resulting
in
the
lead-in
latch not being
opened
by
plate
D
(as
occurs
during auto-return). Consequently,
the tonearm
does
not
stay at the arm rest, but
proceeds
to
move back towards
the
record
for
repeated
play.
Subsequent
operations are the
same
as
during normal autolead-in operation.
.
INTERRUPTION OF
RECORD
PLAY
1.
Press
the START/STOP button.
2.Pin
A of
lever
D
pushes
plate C
to
the
right,
resulting
in
the
plate
C
plate spring
forcing
lever
A
upwards. And this in turn
repels the
detector
assembly.
3. Subsequent steps are the
same as
steps
3
to
10
described
under auto-return.
O MANUAL START AND
STOP
1.
When
the tonearm is
lifted
ovei
to
the disc by
hand,
pin E of the
PU plate rotates lever B in
the
clockwise
direction.
Lever
B is
thereby
disengaged
from
lever
C,
switching
the
micro-
switch on
to
start the motor.
2. When
the tonearm
is
lifted off
the record during
play
and returned
to
the arm rest, pin E
of
the
PU plate rotates lever B in the clockwise
direc-
tion
and this lever thus
presses
against
lever
C.
When lever
C
then
makes contact
with
the
microswitch
(pressing
the
microswitch
push-
button), th motor
is
subsequently
turned
off.
