Put on START/CUT Button
NAND Gate output 10 shall be OV, and TRO1 and AC motor shall be ON.
As soon as AC motor has been ON, SW 10 shall rotate until TRO1 becomes OFF
after SW 10 on the cam at the final stage has again turned over and the cam
at the final stage has turned over half.

Record End
As inside most diameters of LP and EP Groovesare different each other,
operation is also different (Its change can be done by individual r.p.m.)
33 L.peM.
When the slit of Rester Lever comes into Sensor Assembly and the photo
transistor becomes ON by L.E.D. light, NAND Gate output 11 shall be ON and
ACG motor Shall begin to rotate.
45 Y.pem.
When the slit of Rester Lever comes into Sensor Assembly with a photo
transistor's being ON and the tonearm reaches the inside most with the
slit's shutting off L.E.D. light and eventually the photo transistor's
being OFF, NAND Gate output 10 shall be OV and AC motor begins to rotate.
(On this occassion when the tonearm returns, the slit of Rester Lever again
passes through Sensor Assembly and the above mentioned signal shall be input.
However, it is not directly related since AC motor is in operation by SW 10.)
(4) Repeat
When the tonearm returns to the armrest in REPEAT mode, 12V shall be loaded
to the 6P connector by SW 11 and same operation shall be made as in case of
pressing START/CUT button.
REMARKS: As mentioned above be careful for any light from outside to come
especially into Sensor Assembly when you are repairing since this
fll-auto mechanism is optical one.

EXPLANATION ABOUT TRANSISTOR’S
Q 10 280945
When the rotation started by depressing the "Start/Cut" button after the suction
by V.D.S. button, this transistor works to cancel the set signal to FLIP-FLOP
circuit of " V.D.S. on ".
---This prevents the mis-suction when the suction operates again once already
sucked.
Q 171 280945
When the mode is set at " REPEAT ", the reset signal comes into the V.D.S. off
FLIP-FLOP circuit. While the V.D.S. motor is rotating, this transistor operates
to cancel this very reset signal until the motor stops rotating by the reset
Signal coming from SW-07 at the main cam.
---When the mode is set at " REPEAT " while V.D.S. motor is rotating, no problem
to activate "V.D.S. on ". But when the "V.D.S. off " is depressed, V.D.S.
motor stops rotating on the way, and the platter is locked. This transistor was
adopted to avoid this trouble.
While the reset signal of V.D.S. off FLIP-FLOP circuit is to delete memory of V.D.S.
off.
Q 12 250945
This works to cancel DC 12V fed into V.D.S. switch at the "REPEAT" mode.
---This transistor is used so that the V.D.S. on/off switch should not operate at
" REPEAT " mode.
Q 13-1 28C945
This operates to cancel not the set signal to be fed to V.D.S. off FLIP-FLOP
circuit but the set signal to V.D.S. on FLIP-FLOP circuit except in the case that
the tonearm is put on the arm rest position by the tonearm position detecting
switch 09.
Q 13-2 280945
This operate to cancel the output coming from " V.D.S. on/off " FLIP-FLOP circuit
so that the V.D.S. motor should not rotate except when the tonearm is at the arm
rest by the tonearm detector switch 09.
While when the " V.D.S. off " FLIP-FLOP circuit is set on, the V.D.S. operation
starts after the tonearm get back to arm rest position.
---This transistor is adopted so that the platter should not be mechanically locked
even if "V.D.S. on/off " button is switched on while playing.
Q 14 280945
When the tonearm left from the arm rest, the output of V.D.S. on/off FLIP/FLOP
circuit is cancelled by Q 13-2. While the tonearm is placed at the arm rest, V.D.S.
operation starts, and even if the tonearm left the arm rest before the V.D.S.
operation completes, this transistor works to cancel this blocking signal until the
V.D.S. operation is achived.

FULL-AUTO MECHANISM CIRCUIT ALIGNMENT RROCEDURES
There happen to be eccentric record discs among those which are available in markets
and in case these eccentric ones are used for playing, the wave form will be as per Fig.
1 when the rester lever slit passes through the light axis of the sensor.
f\ of
L GE L
Fig.1
When eccentricity is remarkable, the wave form reads as per Fig. 2 and mis-operation
shall be caused as for EP discs.
H Sensor output
Schmidt Trigger Circuit
Level "H"
Schmidt Trigger Circuit
Level "L"
Sensor output L
Fig.2
As return action is made on EP discs when output of schmidt trigger circuit comes to
be "L" from "H", mis-operation shall be caused at the portion of the enlarged curve in
Fig. 2.
So,
prevent
from
mis-operation,
make
the
hysterisis
as
wide
as
possible
and
adjust
output
level of the sensor to it.
Widening of the hysteresis in schmidt trigger circuit will be efective to prevention of
outcoming noises, etc.
Adjustments of the hysteresis and output level of the sensor are made respectively by
the VRO2 and VRO1 as far as the ‘present circuit is concerned.
In the actual procedures firstly adjust the hysteresis and secondly output level of
the sensor.
The hysteresis is not always same since threshold value of IC's varies depending on IC's
to be used.
So, at first adjust "H" level of schmidt trigger circuit to (x-0.8)V by the VRO2 when
output
of
the
sensor
is
"H"
(saturated
state,
provided
to
be
xV),
and
at
this
point
"L"
level (provided to be yV) of schmidt trigger circuit shall be decided.
Secondly adjust "L" level of output of the sensor to (y-0.6)V by the VRO1.
Above is all for adjustment.
Remarks:
As
to
"H"
level
difference
by
0.8V
is
made
between
threshold
values
of
the
sensor
output
and
schmidt
threshold,
and
as
to
"L"
level
difference
by
0.6V
between
the
threshold
values.
Those
values
are
decided
in
consideration
of
changes
in
temperature,
humidity
and
time
process
and
other
drifts
as
well.

SW-07
ay --~
As the pivot of the main cam actuator is eccentric, you can change the timing of
the SW-07 by turning the pivot with a (-) screw driver.
Adjust the main cam actuator so that the motor can stop when the charge lever is
in the at most open status by pushing the V.D.S. on switch (SWO2).
However, as the pivot of main cam actuator plays the circular movement, there are
two points having the same timing between the main cam and main cam actuator.

Be
sure
of
choosing
the
very
position
which
pushes
the
SW-07
more
than
the
other.
After
adjustment,
do
not
forget
to
put
glue.
